Abstract:
  Objective  To investigate the role of HK2 and VDAC1 in diacetylmorphine-induced cardiomyocyte apoptosis.   Methods  A dose-escalation method was used to establish a rat model of diacetylmorphine addiction. Forty SD rats were randomly divided into three groups, the normal group (n=10) was injected with an equal amount of saline subcutaneously, the model group (n=15) was injected with 5 mg/kg of diacetylmorphine for the first time, and then the dose was increased by 2.5 mg/ (kg·d) day by day for 20 days, and the group of model + 10 D (n=15) continued to increase the dose based on the model group up to the 10th day. Lactate dehydrogenase (LDH) and glutamic oxaloacetic transaminase (GOT) were detected by ELISA; HE staining was used to observe the pathological changes of myocardial tissues in each group; TUNEL staining was used to detect apoptosis in myocardial tissues in each group; and immunohistochemistry, RT-q-analysis, and immunochemistry were used to detect apoptosis in myocardial tissues in each group. Immunohistochemistry, RT-qPCR and Western blot were used to detect the mRNA and protein expression of HK2, VDAC1 and apoptosis-related factors.   Results  HE staining revealed that myocardial tissues exhibited different degrees of damage with the prolongation of diacetylmorphine intervention. Compared with the normal group, serum LDH, GOT content and myocardial apoptosis rate increased in the model group, mRNA and protein levels of HK2 and anti-apoptotic factor Bcl-2 decreased, mRNA and protein levels of VDAC1 and pro-apoptotic factors Bax and Caspase-3 increased, and the protein level of Clevead Caspase-3 increased; in the model + 10 D group the above indexes, there was a statistically significant difference (P < 0.05).   Conclusion  Diacetylmorphine can cause cardiomyocyte apoptosis, and VDAC1 may be involved in the process of cardiomyocyte apoptosis caused by diacetylmorphine.

Abstract:
  Objective  To explore the possible effects and the underlying molecular mechanisms of xueshuantong [The main active component is panax notoginseng (PNS)] on the cognitive function and neural excitability of mice with Alzheimer’ s disease (AD).   Methods  The APP/PS1 mice were used as an animal model for AD research, at the stage when amyloid protein was not detected in mice (2 months of age). Mice in the xueshuantong group (APP/PS1+PNS) were administered by gavage once a day at a dose of 60 mg/kg for six months (for 8 months of age). The mice of the control group were given 0.9% sodium chloride (APP/PS1+Vehicle) intragastric treatment of the same volume, while the wild-type mice of the same age were given 0.9% sodium chloride intragastric treatment as the normal control group (WT+Vehicle) (15 mice in each group, n=15). After six months, the cognitive function of the mice was evaluated by the Novel Object Recognition (NOR) task and Morris Water Maze (MWM) test. The activity of BACE1, the distribution and expression of Nav1.1α, as well as the expression and enzymatic hydrolysis of Navβ2 (Navβ2 full-length and Navβ2-CTF fragments) in cortex and hippocampus were detected by EEG, Western blot and cell surface biotinylation assay, respectively.   Results  The NOR task showed that compared with the mice in the APP/PS1+Vehicle group, the Discrimination index (DI) of mice in the APP/PS1 group was significantly increased after xueshuantong administration (P < 0.05). The MWM test found that, the escape latency of the mice in the xueshuantong group was shortened followed six months in gastric administration (P < 0.05), while the stay time in the target quadrant and the number of platforms significantly increased (P < 0.05) after the removal of the platform. The results of EEG recording showed that xueshuantong reduced the frequency of spike-wave discharges in APP/PS1 mice (P < 0.05). Furthermore, xueshuantong significantly reduced the expression of BACE1 (P < 0.05). In the APP+PNS group, the expression of Navβ2 full-length was increased (P < 0.05), as well as corrected the abnormal distribution of Nav1.1α inside and outside of neurons (P<0.05).   Conclusion  Treatment with xueshuantong can significantly improve the learning and memory ability and correct the abnormal excitability of the brain in AD model mice. The mechanism may be related to the inhibition of BACE1 activity, the reduction of APP/PS1-induced excessive enzyme digestion of Navβ2, the correction of the abnormal expression and distribution of Nav1.1α in cortical and hippocampal neurons, as well as the subsequent regulation of neuronal excitability.

Abstract:
  Objective  To observe the effect of a new cell delivery tool (MSC exo) on the proliferation of pancreatic cancer by transferring targeted genes.  Methods  Transmission Electron Microscope (TEM) and Nanoparticle Tracking Analysis(NTA) were used to identify human mesenchymal stem cell exosomes(MSC-exo) and transport miR-450a-5p into CFPAC-1, to explore the effect of miR-450a-5p targeting BZW2 on inhibiting the proliferation of pancreatic cancer cells.  Results  The expression of miR-450a-5p was low in pancreatic cancer tissue (P<0.05), and the expression of CD63 and TSG101 of MSC-exo-miR-450a-5p in CFPAC-1 cells was higher than that of MSC-exo by Western blot(P<0.05). CCK-8 and EdU results showed that MSC-exo-miR-450a-5p significantly inhibited the proliferation of CFPAC-1 cells (P<0.05). Cell scratch and Transwell experiments showed that MSC-exo-miR-450a-5p can inhibit the migration and invasion of CFPAC-1 cells (P<0.05). Through dual luciferase assay, it was confirmed that miR-450a-5p targets BZW2, and RT-qPCR and Western blotting showed a negative correlation (P<0.05) between miR-450a-5p and BZW2 expression. Overexpression of BZW2, CCK-8, EdU, cell scratch, and Transwell experiments confirmed that pc-BZW2 reversed the anti-cancer function of MSC-exo-miR-450a-5p on CFPAC-1. Western blot detected PCNA,Ki-67,MMP2,MMP9, and the results were consistent with the above experiments (P<0.05).  Conclusion  hMSC exo is a new delivery system, targeting BZW2 to transport miR-450a-5p to inhibit the biological malignancy of pancreatic cancer cells, which provides an important clue for the research of targeted treatment of pancreatic cancer.

Abstract(880) HTML PDF(8)
Abstract:
  Objective   Meta-analysis was conducted to assess the risk of secondary infection caused by tocilizumab (TCZ) in the treatment of Corona Virus Disease 2019 (COVID-19), in order to provide an evidence-based basis for the safety of tocilizumab in patients with COVID-19.   Methods   Cochrane Library, PubMed, Web of Science, CNKI, SinoMed and Wanfang databases were searched in computer to collect randomized controlled trial and cohort study of treating COVID-19 with tocilizumab from December 19, 2019 to December 30, 2022. A meta-analysis of the results of each study was performed using RevMan 5.4.1 software.   Results   A total of 1691 references were screened and eighteen studies involving 3933 patients were included. The incidence of secondary infection in the tocilizumab with the standard treatment group and standard treatment group was 19.14% (331/ 1729) and 12.11% (267/ 2204), respectively. Meta-analysis showed that the tocilizumab + standard treatment group had a higher incidence of secondary infection than the standard treatment group [RR = 1.35, 95%CI (1.05, 1.74), P = 0.02]. The results of the subgroup analysis showed that the risk of secondary infection with different doses of tocilizumab was different. The incidence of secondary infection was significantly higher in the subgroup with doses of 400~800 mg/d tocilizumab than in the standard care group [RR = 1.48, 95%CI (1.19, 1.84), P = 0.0004]. The incidence of secondary infection in subgroups with doses of ≤400 mg/d tocilizumab was also significantly higher than that in the standard treatment group [RR = 1.87, 95%CI (1.28, 2.72), P = 0.001]. However, there was no statistical significance between the subgroup 6~8 mg/kg tocilizumab and the standard treatment group.   Conclusions   Tocilizumab may increase the risk of secondary infection in patients with COVID-19 compared with standard treatment, and the benefits and risks of tocilizumab should be carefully evaluated before clinical administration. Moreover, large and high-quality studies are needed for further evaluation.

Abstract(1436) HTML PDF(18)
Abstract:
  Objective   To explore the role of TMAO from gut microbiota in non-alcoholic fatty liver disease (NAFLD), we detected the serum level of TMAO and its precursor metabolites in NAFLD, as well as the expression level of Eubacterium rectum, Bacteroidetes multiforme, Lactobacillus and bifidobacterium in the intestinal flora.   Methods   We collected 118 subjects and divided into NAFLD group (86 cases) and healthy control group (32 cases) randomly. We also detected the serum level of TMAO and its precursor metabolites in subjects by high performance liquid chromatography tandem mass spectrometry detection (LC-MS), and the expression of target bacterial DNA was detected by qRT-PCR.   Results  Serum TMAO, TMA and choline levels were significantly increased in NAFLD (P<0.05), and liver fat content was positively correlated with TMAO (P<0.05). The expression level of Lactobacillus and Eubacterium rectum in NAFLD group were increased (P<0.05); the expression level of Bifidobacterium and Bacteroides multiform were decreased (P<0.05).The serum TMAO level was positively correlated with Eubacterium rectum (r=0.280, P<0.05), and negatively correlated with Bifidobacterium (r=-0.332, P<0.05).   Conclusion   The level of TMAO in serum shows a positive correlation with NAFLD. The structure of intestinal flora in individuals with NAFLD is altered and linked to TMAO. This suggests that the intestinal flora may have a significant impact on the development of NAFLD through TMAO.

Abstract(860) HTML PDF(11)
Abstract:
  Objective  To compare the clinical efficacy of abdominal ultrasound-guided endoscopic retrograde appendicitis therapy (ERAT) with laparoscopic appendectomy (LA) for acute uncomplicated appendicitis using propensity score matching.   Methods  The clinical data of 441 patients with acute uncomplicated appendicitis admitted to the Third People's Hospital of Yunnan Province from March 2020 to April 2023 were collected. The cases were classified based on the differences in surgical method and divided into the ERAT group (n = 30) and LA group (n = 411). The clinical efficacy of patients was compared between the two groups after reducing confounding bias by propensity score matching (PSM).   Results  After PSM, a total of 30 pairs of patients in the two groups were successfully matched, and the baseline data of the two groups met the requirements for comparability. At 24 hours after the operation, the ERAT group exhibited lower white blood cells, neutrophil counts, and C-reactive protein levels compared to the LA group, and these differences were statistically significant (P < 0.05). There was no significant difference in the operation time and total effective rate between the ERAT group and the LA group (P > 0.05). However, the ERAT group had lower intraoperative blood loss and shorter pain relief time compared to the LA group, and these differences were statistically significant (P < 0.05).   Conclusion  Abdominal ultrasound-guided endoscopic retrograde appendicitis treatment is an effective, safe, and feasible technique with good prospects for the treatment of acute uncomplicated appendicitis.

Abstract:
  Objective  To assess the nutritional status of vitamin D and associated factors among adults of six ethnic minority groups native to Yunnan Province, and provide evidence for policy making.   Methods  Between May 2019 and August 2020, a total of 690 adults were selected from Jinuo, Bulang, Jingpo, Deang, Achang and Pumi ethnic groups according to the sex and age composition in the 6th national census. A questionnaire survey and an anthropometric examination were conducted by trained health workers, and serum 25(OH)D levels were determined with high-performance liquid chromatography-tandem mass spectrometry.   Results  The median of serum 25(OH)D was 28.7(P25~P75∶24.3~33.8) ng/mL, and the prevalence of vitamin D sufficiency, insufficiency and deficiency were 44.2%、47.5% and 8.3%, respectively. There were significant differences in serum 25(OH)D levels among the six ethnic groups(χ2=139.29, P < 0.01). Multivariate logistic regression showed that ethnic groups living in higher latitude areas(Pumi, Jingpo, Deang, and Achang), women, and those whose BMI≥24.0 were more likely to be vitamin D insufficient or deficient.   Conclusion  More than half of the ethnic adults suffer from vitamin D malnutrition which also varies across ethnicities. Further surveillance and interventions among key areas and populations are needed.

Abstract:
  Objective  To apply ultrasound to monitor cardiac function changes after anthracycline exposure in children with acute leukemia, in order to obtain the indicators of early changes in their cardiac function.   Methods  Children with acute leukemia from 2018 March to December 2020 in the Children’ s Hospital of Kunming Medical University were enrolled according to the inclusion and exclusion criteria, their routine cardiac ultrasound and tissue Doppler condition were recorded, and the changes in systolic function were evaluated by Tei index including TeiS, TeiRL, TeiM and TeiT.   Results  The mean values of LVEF in the normal and the experimental group were both above 60%. FS, SV, and EDV were all in the normal range. While common indicant, the index of TDI or Tei was not statistically significant(P>0.05). The levels of TeiM, TeiRL and TieT in the groups that received a total dose of 200 mg/m2 anthracyclines and 250 mg/m2 were significantly different from that before treatment(P<0.05).   Conclusion  Tei index can be utilized as a sensitive indicator for early changes in left and right heart function after children with acute leukemia are exposed to anthracyclines.

Abstract:
  Objective   To explore the clinical characteristics and risk factors of death during hospitalization in patients with community-acquired pneumonia(CAP) complicated with diabetes mellitus(DM).   Methods   A retrospective analysis was performed on 566 patients with CAP hospitalized in the Second Affiliated Hospital of Kunming Medical University from January 2018 to January 2022. The patients were divided into simple CAP group(n=478) and CAP combined with diabetes(CAP+DM) group(n=88) according to whether they had diabetes, and then CAP+DM group(n=88) was divided into survival group(n=69) and death group(n =19) according to whether the patients died during hospitalization. The clinical data and laboratory test indicators of patients in different groups were compared. Cox regression analysis was used to screen the risk factors of death during hospitalization in the CAP+DM group. Receiver operating characteristic(ROC) curve was plotted to evaluate the predictive value of independent risk factors on hospitalization death.   Results   Compared with the simple CAP group, the CAP+DM group had significant differences in age, concomitant hypertension, coronary heart disease, CURB-65 score, neutrophil to lymphocyte ratio(NLR), C-reactive protein(CRP), procalcitonin(PCT), albumin(ALB), prealbumin(PA), glucose(GLU), serum potassium(K), calcium(Ca), phosphorus(P), magnesium(Mg), lactic acid(Lac), non-invasive ventilation time, ICU occupancy rate and mortality rate(P < 0.05); Compared with the survival group, there were statistically significant differences in CURB-65 score, NLR, CRP, PCT, GIU, ALB, PA, serum iron(Fe), Ca, non-invasive ventilation time, and ICU admission rate among the death group patients(P < 0.05). Cox regression analysis showed that the increase of NLR level and the decrease in PA level were the risk factors for in-hospital death in patients with CAP complicated with diabetes(P < 0.05). When the PA cutoff value was 91 mg/L, the AUC, sensitivity, and specificity for predicting in-hospital death of CAP patients with diabetes were 0.849, 84.2% and 81.2%, respectively.   Conclusion   Patients with CAP combined with diabetes are more serious and have worse prognosis than those with CAP alone. PA has a good predictive value for the prognosis of these patients. Early detection and active intervention should be carried out to reduce the in-hospital mortality of patients.

Abstract:
Inflammatory Bowel Diseases (IBD) is a class of genetically related diseases caused by multiple genes and environmental factors that accelerate the disturbance of the immune-gut-microbiome axis. Lesions often involve multiple organs and systems. Biological agents are an important means of treating IBD and its extraintestinal manifestations. Current studies suggest that biologics can bring benefits to patients, but paradoxical skin lesions, joint lesions, and ocular lesions appear during the treatment. Diseases, pulmonary lesions and other manifestations or lesions are easily ignored in clinical practice, thereby delaying the patient's condition and affecting the patient's quality of life. Therefore, by summarizing the clinical characteristics and diagnosis and treatment experience of contradictory extraintestinal manifestations in the current application of biological agents, this review aims to improve the understanding of clinicians, identify this clinical manifestation early, and avoid delaying the patient's condition.
