Abstract:
  Objective   To investigate the expression and clinical significance of PDE4D in ovarian cancer by excavating gene information in Oncomine and explore the effect of sanguinarine on PDE4D by cells experiment.   Methods   PharmMapper was used to find the targets matched with the pharmacodynamic groups of sanguinarine. The gene information about PDE4D in ovarian cancer research was collected in Oncomine, and the expression level was analyzed. The A2780 and SKOV3 ovarian carcinoma cells were divided into control group and sanguinarine group. CCK8 and RT-qPCR were used to detect the effects of sanguinarine on the proliferation and PDE4D mRNA expression of A2780 and SKOV3 cells.   Results   PDE4D was the target matched with the pharmacodynamic group of sanguinarine. There were 6 studies referred to PDE4D in ovarian cancer and normal sample collected in the Oncomine. The expression of PDE4D in tumor tissues was significantly higher than that in normal (P < 0.05). The cell experiments showed that compared with the control group, the proliferation of A2780 and SKOV3 cells was significantly inhibited and the expression of PDE4D mRNA was decreased in the sanguinarine group, with statistical significance (P < 0.05).   Conclusions   PDE4D gene may play a role in the occurrence and development of ovarian cancer, and sanguinarine can inhibit the growth of ovarian cancer cells, which may be related to the down-regulation of PDE4D expression.

Abstract:
  Objective  To screen the pathogenic mutations in the four generations of a proband with atrial septal defect, so as to analyze the relationship between genotype and phenotype by whole exon sequencing and Sanger sequencing.   Methods  Retrospectic analysis of the clinical data on a child with atrial septal defects treated in the Department of Cardiovascular Surgery, the First People’ s Hospital of Yunnan Province was conducted in tandem with genetic tests for the sick child, his younger brother and mother by means of whole-exome sequencing to find out the genetic causes of the family in combination with bioinformatics analysis. Meanwhile, sporadic ASD patients and healthy people were screened for the Caudal Homebox Gene 4 (CDX4) mutation found in the family.   Results  The cardiac ultrasound results of the sick child and the intraoperative findings conformed with ASD diagnosis. The genetic tests suggested that CDX4 gene c.C233T homozygous mutation occurred to the child, his mother carries heterozygous mutation of the gene and his younger brother homozygous mutation of it. Codon 233 of exon 1 of CDX4 gene mutated from C to T (c.C233T), leading to conversion of amino acid 78 from proline to leucine (p.P78L). Multi-species comparison showed that the locus was highly conserved. The three software programs PROVEAN, Mutation Taster and Mutation Assessor suggested that the mutation was harmful. Of the 198 patients with sporadic atrial septal defects, 5 suffered this gene mutation, but that was not found in the 265 healthy people. According to the Fischer’s Exact Test, CDX4 gene c.C233T homozygous mutation was associated with congenital heart diseases (P = 0.014).  Conclusion  CDX4 gene c.C233T (p.P78L) homozygous mutation is the highly likely the pathogenic mutation of the family.

Abstract:
  Objective  To explore the potential mechanism of thioridazine in the treatment of cervical cancer by bioinformatics analysis.   Methods  The target genes that can interact with thioridazine was predicted by PharmMapper, and then conducted pathway and tissue expression enrichment analysis by STRING online tool. The cervical cancer related genes were screened through GeneCards and DisGeNET databases, and cross the target genes of thioridazine to obtain the interaction genes that thioridazine may act on cervical cancer. The protein-protein interaction(PPI) network was constructed using STRING, and the core targets were speculated and evaluated their importance.The GO and KEGG enrichment analysis were conducted using clusterProfiler package.   Results  A total of 47 target genes were predicted by PharmMapper, which were enriched in tumor-related pathways and cervical cancer cells. Intersection with 669 cervical cancer genes, 21 common genes were obtained, of which 10 key genes were EGFR, PPARG, AR, NOS3, ALB, ESR1, MAPK1, MAPK14, ANXA5 and MAPK8. These key genes were important in the cervical cancer PPI network. The biological processes involved in interactive genes mainly include positive regulation of anion transport, peptidyl-serine phosphorylation, steroid metabolic process, blood coagulation, and cellular response to chemical stress. Enriched KEGG pathways include pathways in cancer, relaxin signaling pathway, endocrine resistance, proteoglycans in cancer, cellular senescence, GnRH signaling pathway, and VEGF signaling pathway.   Conclusion  Thioridazine has potential anti-tumor effects and may play a role in the treatment of cervical cancer through multiple targets and multiple signaling pathways.

Abstract:
  Objective  To explore effect of the Willed movement on behaviours of rats with focal cerebral ischemia and the expression of GluA2 and N-cadherin in the brain tissue around ischemia.   Methods  We selected clean-level healthy male SD rats, and prepared 144 middle cerebral artery occlusion (MCAO) models by thread occlusion method, and randomly divided them into model (MCAO) group, environment modification (EM) group, control rehabilitstion (CR) group and Willed movement (WM) group, each group was divided into four subgroups of 7, 15, and 30 days according to the postoperative time. The behavioral changes of rats in each group were dynamically observed, and the expression changes of GluA2 and N-cadherin protein in the brain tissue around the ischemic area were observed by immunohistochemical staining.   Results  On 7, 15, and 30 days after reperfusion, the climbing frequency of rats which were treated by willed movement was obviously higher than EM and CR group (P < 0.01). After 30 days of reperfusion, the neurological deficits score of the intentional exercise intervention group was lower than MCAO rats (P < 0.05). Compare with MCAO rats, the expression levels of GLUA2 and N-cadherin were higher in ischemic penumbra (P < 0.05).   Conclusions  Willed movement can promote the recovery of damaged nerve function after focal cerebral ischemia, which may be related to up-regulating the expression of GLUA2 and N-cadherin in the brain tissue around the ischemic focus and enhancing synaptic plasticity.

Abstract:
  Objective  To explore the feasibility of short-term indwelling urete in patients aftert PKEP (transurethral plasmamakinetic enucleation surgery).   Methods  We performed a retrospective analysis of the clinical data of 89 patients with benign prostatic hyperplasia (BPH) and treated with PKEP in Yan'an Hospital Affiliated to Kunming Medical University from February 2019 to December 2019. These patients was divided into control group and observation group. The control group was given indwelling with the urine after PKEP, and the observation group left the urete after PKEP short-termly. Compared to the operation time, intraoperative blood volume, resection of gland weight, and other related indicators.   Results  The surgical time of the control group and the observation group was [(58.40 ± 29.80) min vs (67.40 ± 29.80) min], the weight of the gland was [(54.90 ± 16.60) g vs (61.20 ± 21.50) g], the volume of intraoperative bleeding was [(35.50 ± 13.20) mL vs (35.50 ± 19.20) mL], the difference was not statistically significant (P > 0.05). However, the observation group was hospitalized [(10.80 ± 3.90) D], hospitalization cost [(1.06 ± 0.49) D VS. (1.38 ± 0.53) d] was significantly lower than that in the control group (P < 0.05) . There was no significant difference between the two groups (P > 0.05) in the incidence of urinary retention, urinary tract infection, urinary incontinence complications.   Conclusions  After the operator strictly abides by the PKEP operating standard, postoperative short-term indwelling urete can shorten the hospitalization time and reduce the hospitalization cost without increasing the incidence of postoperative complications. It not only achieves a good therapeutic effect, but also reduces the economic burden of patients. These findings verifies the feasibility of this method.

Abstract:
  Objective  To explore the risk factors of lymph node metastasis in patients with gallbladder cancer, and to provide references for comprehensive treatment and prognosis evaluation of gallbladder cancer.   Methods  We retrospectively analyzed the clinical and pathological data of patients with gallbladder cancer confirmed by postoperative pathological examination who underwent radical resection of gallbladder cancer in the Second Affiliated Hospital of Kunming Medical University from January 1, 2013 to September 30, 2020. The patients were divided into Lymph node metastasis group and non-lymph node metastasis group, univariate and multivariate analysis was used to determine the relevant risk factors of gallbladder cancer lymph node metastasis.   Results  A total of 101 patients were finally included, of which 41 patients had lymph node metastasis and 60 patients had no lymph node metastasis. The univariate analysis showed that T stage, histological grade, liver invasion, preoperative CA19-9≥100 U/mL and preoperative CA19-9+CEA+CA125 combination were risk factors for lymph node metastasis of gallbladder adenocarcinoma(P < 0.05). The results of multivariate analysis showed that T stage, histological grade, and preoperative CA19-9+CEA+CA125 combination were independent risk factors for lymph node metastasis of gallbladder adenocarcinoma(P < 0.05).  Conclusions   Patients with gallbladder adenocarcinoma with CA19-9≥100 U/mL or CEA≥20 ng/mL or CA125≥50 U/mL should consider expanding the scope of lymph node dissection. For patients with gallbladder adenocarcinoma with T3-T4 staging, histological grade G3-G4 and preoperative CA19-9≥100 U/mL or CEA≥20 ng/mL or CA125≥50 U/mL, comprehensive postoperative treatment and close follow up should be considered.

Among 221 urine samples from infants as well as their maternal milk samples, the positive rate of maternal milk samples was higher than that of urine or serum. When the maternal milk samples were negative, 0.58% of the children’ s urine samples were positive; When the maternal milk samples were positive, the children’ s urine were negative.   Conclusions  The positive rate of HCMV-DNA in maternal milk samples is significantly higher than that in other types of samples. Therefore, for pregnant women or infants with suspected infected HCMV, it’ s recommended to collect milk samples for the test. However, HCMV-DNA detected in maternal milk can’ t fully reflect the detection of infant body fluid samples. As age goes on, the positive rate of infant urine will increase. It is necessary to collect fluid samples at different periods for the test, and analyze comprehensively the test results.

Abstract:
  Objective  To compare the effects of hydromorphone and sufentanil on early postoperative cognitive function in patients with colorectal cancer.   Methods  Eighty-five patients with selective radical resection of colorectal cancerr (including laparoscopic surgery or open surgery) were randomly divided into hydromorphone group of 44 (H group) and sufentanil group of 41 (S group) by random number table method. Postoperative H group was treated with hydromorphone for intravenous analgesia. Group S was treated with sufentanil for intravenous analgesia. Visual analogue score (VAS) was recorded at 6, 12, 24, 48 h after surgery. The adverse reactions such as nausea, vomiting, skin itching, respiratory inhibition, hypotension and dizziness occurred within 48 hours after the operation were observed. Ramsay sedation score was recorded 24 hours after surgery. Mini-Mental State Examination (MMSE) scores were recorded at 1, 2, 3 d after the operation were recorded.   Results  There was no significant difference in postoperative VAS scores between the two groups (P > 0.05). There was no statistically significant difference in the incidence of adverse reactions between the two groups within 48 hours after surgery (P > 0.05). There was no statistically significant difference in Ramsay sedation score at 24h after surgery between the two groups (P > 0.05). There was a statistical difference in the postoperative MMSE score between the two groups (P < 0.05). The incidence of postoperative cognitive dysfunction (POCD) in group H was 15.9% (7/44), and group S 39% (16/41). There was a statistical difference in the incidence of POCD between the two groups (P < 0.05). The grouping factor was an independent one affecting the occurrence of POCD (OR = 3.307, P < 0.05).   Conclusions  Hydromorphone and sufentanil are both safe and effective for intravenous controlled analgesia in patients after radical resection of colorectal cancer with no difference in analgesia. Compared with sufentanil, hydromorphone can significantly improve the cognitive impairment of patients after radical colon cancer.

Abstract:
  Objective  To evaluate the value of multimodal ultrasound in monitoring renal function and postoperative complications of DBD transplantation.   Methods  67 cases of brain dead organ donor kidney transplantation (DBD) in Ganmei Hospital Affiliated to Kunming Medical University from July 2019 to June 2021 were selected to evaluate the transplanted kidney by multimodal ultrasound. The transplanted kidneys were divided into normal function group and abnormal group according to blood creatinine. The abnormal group was divided into acute rejection group, chronic rejection group, viral nephropathy group, fibrosis group and drug injury group according to puncture pathology. The correlation between arterial peak velocity (PSV), diastolic velocity (EDV), resistance index (RI) and serum creatinine was analyzed. To compare the diagnostic efficacy of contrast-enhanced ultrasound with pathology or DSA in renal transplantation complications, and to analyze the correlation between contrast-enhanced ultrasound parameters and renal transplantation function. Rank sum test was used to compare the young’ s modulus between abnormal group and normal group. The ROC curve was drawn, and the young’ s modulus at the highest yoden index was used as the cut-off value to distinguish normal and abnormal transplanted kidneys, and the corresponding sensitivity and specificity were calculated.   Results  The correlation between blood flow parameters of transplanted kidney and serum creatinine was general, and the correlation coefficients were less than 0.5. The arrival time and peak time of chronic rejection group (8 cases) were significantly longer than those of normal group (10 cases), and the difference was statistically significant. Two cases of pseudoaneurysm, two cases of graft ischemia and one case of graft venous thrombosis were diagnosed by contrast-enhanced ultrasonography, which were confirmed by pathology or DSA. According to the serum creatinine value, 62 cases of transplanted kidney were divided into 22 cases in the normal group and 40 cases in the abnormal group (5 cases in the acute rejection group, 11 cases in the chronic rejection group, 10 cases in the viral nephropathy group, 10 cases in the fibrosis group and 4 cases in the drug injury group). The RI of renal aorta in acute rejection group was higher than that in normal group, the RI of interlobar artery in chronic rejection group was higher than that in normal group, the EDV of main and interlobar artery was lower than that in normal group, the PSV of interlobar artery was lower than that in normal group, and the main PSV of fibrosis group was lower than that in normal group. The above differences were statistically significant (P < 0.05); There was no significant difference in parameters between viral nephropathy, drug injury group and normal group (P > 0.05). The young’ s modulus of ste in abnormal group and normal group were 22.550 (17.1, 28.1) and 13.370 (11.8, 15.9) kPa, respectively (P < 0.01). When the cut-off value = 17.31 kpa, the sensitivity and specificity of shear wave elastography in the diagnosis of renal allograft lesions were 75% and 91%. The young’ s modulus of STQ in abnormal group and normal group were 21.760 (16.4, 33.4) and 13.870 (10.5, 16.8) kPa, respectively, with significant difference (P < 0.01). When the cut-off value = 18.16 kpa, the sensitivity and specificity of shear wave elastography in the diagnosis of renal allograft lesions were 70% and 91%. The young’ s modulus of ste in acute rejection group, chronic rejection group, viral nephropathy group, fibrosis group and drug injury group were 13.370 (11.8, 15.9), 15.550 (13.4, 16.6), 26.870 (21.6, 38.6), 26.660 (19.5, 34.2), 16.310 (13.2, 23.1) and 27.690 (24.6, 29.2) respectively; The young’ s modulus values of STQ were 13.870 (10.5, 16.8), 16.330 (15.5, 17.4), 23.780 (19.2, 40.7), 22.760 (19.9, 36.0), 16.540 (14.5, 26.0) and 33.355 (29.1, 35.4) respectively. There was significant difference among the groups (P < 0.05). The chronic rejection group, viral nephropathy group and drug injury group were significantly higher than those in the normal group (P < 0.05), but there was no significant difference between the acute rejection group, fibrosis group and the normal group (P > 0.05). The elastic value of viral nephropathy was higher than that of acute rejection, ste: 26.660 (19.5, 34.2) vs 15 550 (13.4, 16.6)kPa (P<0.01), STQ: 22.760 (19.9, 36.0)vs16. 330 (15.5, 17.4) kPa (P < 0.01), the difference was statistically significant.   Conclusions  The blood flow parameters of transplanted kidney can early evaluate the function of transplanted kidney, and have guiding significance for the differentiation of normal, acute and chronic rejection and viral nephropathy. Contrast-enhanced ultrasound has guiding significance in the differentiation of renal transplant complications. Elastography can noninvasively evaluate the hardness of transplanted kidney, and has a certain clinical value in the timely detection of transplanted kidney complications and differential diagnosis.

Abstract:
  Objective  To compare the values of AIMS65, GBS, MGBS, EGBS, CRS, CANUKA, Child-Turcotte-Pugh (CTP), MELD, and MELD-Na scoring systems in the evaluation of the prognosis of patients with liver cirrhosis and EGVB, and explore the factors affecting the poor prognosis of patients with liver cirrhosis and EGVB.   Methods  A total of 169 patients diagnosed with liver cirrhosis and EGVB were divided into a good prognosis group and a poor prognosis group according to whether the patients had rebleeding or death in the hospital. The scores of each model at the time of admission of each patient were calculated, and the clinical characteristics of the two groups of patients were compared.   Results  There were 35 cases in the poor prognosis group and 134 cases in the good prognosis group. The scores of the poor prognosis group were higher than those of the good prognosis group. The AIMS65 score was the best in predicting whether the patient had a poor prognosis, and the difference was statistically significant (P < 0.05). The HB and ALB in the good prognosis group were higher than those in the poor prognosis group, and the PT and INR were lower than those in the poor prognosis group. The difference was statistically significant (P < 0.05). Multivariate logistic regression analysis suggested that ALB may be an independent protection factor for poor prognosis in patients with liver cirrhosis and EDVB.   Conclusion  AIMS65 is the best scoring system for prognostic evaluation of patients with liver cirrhosis and esophageal varices bleeding; ALB may be an independent protective factor for the poor prognosis of patients with liver cirrhosis and esophageal and gastric varices bleeding.

Abstract:
  Objective   To explore outcome of online learning during the period of Covid-19 pandemic, and provide the theoretical basis for blended teaching methods of online and offline.   Methods   A total number of 917 undergraduates at a University in Kunming, were randomly selected to the survey. The survey was conducted by “Questionnaire Star”, and utilized multistage stratified cluster sampling method. Moreover, the survey was designed to investigate the factors that may influence the outcome of remote learning, including learning resources, teaching methods, and learning process.   Results   We found that participants preferred to use mobile phones for remote learning than any other electronic devices. Meanwhile, there was a significant difference between network connection status and learning efficiency (P < 0.05). However, learning efficiency was considered as “average” regardless of teaching methods. The degree of teacher’ s supervision was significantly correlated with learning status ( P < 0.05). Therefore, students’ self discipline, teaching methods, subjective interest, and teacher’ s degree of supervision were the four main factors which may influence virtual learning efficiency. Yet, comparing with the average scores of students on spring semester of 2019 and 2020, there was no significant difference ( P > 0.05).   Conclusion   It is necessary to consider multiple factors that may affect remote learning efficiency, which may imply that instructors would integrate various of online resources and strengthen the supervision of online teaching in order to improve learning outcomes. Since there was no significant difference between pre-and post pandemic period, it may suggest that intensive learning could help online learning efficiency.

Abstract:
  Objective  To investigate the mental status of the patients in rheumatic immunology department, and evaluate the risk of depression and suicide, so as to identify the patients with depression and high risk of suicide, ensure the safety of the patients.   Methods  Patients in the Department of Rheumatology of the First Affiliated Hospital of the Wenzhou Medical University from October 2018 to September 2019 were included in the study. All the patients were investigated with the health questionnaire depression symptom cluster scale (PHQ-9) at the time of admission, the depression status and suicide risk were assessed.   Results  Data of 861 patients were collected. The prevalence of mood disorder, moderate depression and suicide risk were 24.62% , 7.43% and 3.72% respectively. The rate of suicide risk was 2.56% in patients with systemic lupus erythematosus (SLE), ankylosing spondylitis (AS), sjogren’ s syndrome (SS), rheumatoid arthritis (RA) and metabolic arthritis (MA), and the rate of moderate to severe depression was 3.13%. The incidence of depression in patients with different diseases was significantly different (χ2 = 27.734, P < 0.0001). Fish analysis showed that there was significant difference in the proportion of patients with moderate depression or above (χ2 = 13.187, P < 0.05) . The prevalence of depression was significantly higher in SLE patients than in the other four groups, and the rates of moderate to severe depression and suicide were also higher than in the other groups.   Conclusions  The prevalence of depression and suicide risk is high in patients with rheumatic diseases, and the incidence of depression is positively correlated with the PHQ-9 score. The application of simple mental state screening by PHQ-9 score bank on admission of nursing staff is helpful to carry out nursing path intervention by grading and classification, might reduce the incidence of patient suicide and medical disputes.

Abstract:
  Objective  To explore the effect of mechanical vibration of electric toothbrush on neonatal sputum excretion.   Methods  120 children with neonatal infectious pneumonia were randomly divided into control group and experimental group. The control group received electric sputum suction nursing according to the conventional method, and the experimental group received electric sputum suction after mechanical vibration with electric toothbrush. The disappearance time of symptoms, the hospital stay and the changes of blood gas analysis indexes and lung ultrasound before and after treatment were compared between the two groups.   Results  The symptom disappearance time and hospitalization time of children in the electric toothbrush mechanical vibration assisted expectoration group were shorter than those in the control group (P < 0.05). After treatment, the results of blood gas analysis index PaO2 in the experimental group were higher than those in the control group, and PaCO2 was lower than those in the control group (P < 0.05). Dynamic observation of the changes of pulmonary ultrasound images of children in the two groups before and after treatment showed that the time of signs such as the gradual reduction of B line, the recovery of pleural line and a line, and the reduction of consolidation range in the experimental group were significantly less than those in the control group.   Conclusion  Mechanical vibration before sputum suction for neonatal infectious pneumonia can make sputum discharge more fully, so as to improve the treatment effect, and the operation is simple and is worthy of clinical application.
