Abstract:
  Objective  To study the difference of fatty acid composition of lacquer oil obtained from different raw materials and extraction methods of lacquer seed in Nujiang Prefecture of Yunnan Province.   Methods  Black and white lacquer seed were used as experimental materials to extract the oil by selecting different parts and extraction methods. The fatty acids in the obtained oil were detected by gas chromatography-mass spectrometry.   Results  The results showed that there were abundant fatty acids in lacquer seed oil extracted from lacquer seed kernel by Soxhlet extraction. The content of unsaturated fatty acids was more than 70%, and the content of linoleic acid was about 60%. It was suitable for edible oil. The commercial edible lacquer seed oil and lacquer seed oil obtained from the whole lacquer seed by traditional pressing process and Soxhlet extraction are mainly saturated fat, with palmitic acid content of 60~70%. Due to improper packaging and storage, the types and content of unsaturated fatty acids in the commercial edible lacquer seed oil are reduced, resulting in lower nutritional value. The content of oleic acid and linoleic acid in white lacquer seed oil was higher than that in black lacquer seed oil, while the content of linolenic acid in black lacquer seed oil was higher (P < 0.05). Black lacquer seed oil also contains about 1% palmitoleic acid. Therefore, the selection of raw materials and pressing technology has a great influence on the fatty acid composition and nutritional value of the obtained oil.   Conclusion  This study provides data reference for the development and utilization of lacquer seed resources.

Abstract:
  Objective  To explore the clinical significance of HPV in oropharyngeal squamous cell carcinoma.   Methods  A total of 129 patients who were diagnosed and treated in Yunnan Tumor Hospital and met the inclusion criteria in oropharyngeal cancer from January 2010 to December 2019 were selected as the research subjects. The collected pathological specimens were detected using HPV16/18 DNA probes and HPV 6/11 DNA probes. SPSS 24.0 statistical software was used for data analysis.   Results  The positive rate of HPV in this study was 39.53%, all of which were high-risk HPV 16/18 infection. The positive rate was highest in tonsil area and tongue root area. The number of cases with the onset age less than 60 years (P = 0.041) and the early stage (P = 0.001) in the HPV positive group was significantly higher than that in the negative group. The number of long-term smoking cases in the negative group was significantly higher than that in the positive group (P = 0.012). The treatment effective rate of patients in the HPV positive group is higher than that in the HPV negative group.   Conclusion  Compared with HPV-negative oropharyngeal squamous cell carcinoma, patients with HPV-positive oropharyngeal squamous cell carcinoma have a younger onset, early stage, fewer long-term smokers, and are more sensitive to radiotherapy and chemotherapy.

Abstract:
  Objective  To retrospectively analyze the characteristics of infection indicators of antituberculosis drug-related liver injury in patients with pulmonary tuberculosis combined with HIV versus those with pulmonary tuberculosis alone, and to assess clinical risk factors and correlations.   Methods  Patients with liver injury induced by antituberculosis drugs were collected, including 55 cases of pulmonary tuberculosis and 39 cases of pulmonary tuberculosis combined with HIV infection. Clinical data were recorded, fasting venous blood was collected, CD3+, CD4+ and CD8+ T cell ratios were detected by flow cytometry, and serum PCT, IL-6, CRP, SAA and ESR were detected by ELISA.   Results  There were no significant differences in age, gender composition, height, weight and body mass index between the two groups, and the immune function of the two groups were compared, the expression of CD4+ T lymphocytes and CD4%, CD CD4/CD8% were statistically different (P < 0.05). The levels of CRP and SAA in inflammatory indexes were higher in patients with single pulmonary tuberculosis (P < 0.05), and the degree of liver injury in patients with TB and HIV was lower than in the group of patients with TB alone, suggesting that the diseased population with normal immune function, which has a strong inflammatory response, is one of the risk factors leading to liver injury in the treatment of anti-tuberculosis drugs. Also this study showed that SAA was strongly correlated with the severity of liver injury in the tuberculosis group with anti-tuberculosis drug liver injury and the results were statistically significant (P < 0.05). In the pulmonary TB with HIV infection group, IL-6 was closely associated with the severity of liver injury and the results were statistically significant (P < 0.05).   Conclusions  Infection indicators are expressed differently in anti-tuberculosis drug liver injury with different types of patients. The increase of SAA and IL-6 is related to the severity of anti-tuberculosis drug liver injury in different types of patients.

Abstract:
  Objective   To explore the risk factors and early clinical characteristics of neonatal necrotizing enterocolitis (NEC), so as to improve the early warning of NEC and early intervention, so as to improve the prognosis of NEC.   Methods   A total of 95 children diagnosed with NEC in our NICU from November 22, 2017 to November 22, 2020 were collected, and 95 non-NEC children in the same period were selected as the control group according to the 1∶1 matching ratio. The univariate variables were screened by χ2 test, and then multivariate Logistic regression analysis was performed. The count data were analyzed by t test and rank sum test, and the rank data were analyzed by Spearman rank correlation test, α= 0.05.   Results   It suggested that premature birth, low birth weight, infection and mechanical ventilation were independent risk factors for NEC, and abdominal distention and gastric retention were the main clinical manifestations in the early stage. There was no significant correlation between leukocytes and neutrophils and the severity of NEC, while C-Reactive Protein and procalcitonin were positively correlated with the severity of NEC. Lymphocytes and platelets were negatively correlated with the severity of the disease, (P < 0.05 ). Abdominal orthostatic X-ray had no obvious specificity for the early diagnosis of NEC.   Conclusion   When the children have the premature birth, low birth weight, infection and mechanical ventilation risk factors, abdominal distension and poor feeding performance, accompanied by the increase of C-reactive protein and procalcitonin, it is necessary to be alert to the occurrence of NEC, and dynamic abdominal orthostatic X-ray and abdominal ultrasound can be performed to improve the early diagnosis rate.

Abstract:
  Objective  To explore the value of color Doppler ultrasonography (CDU) signs, fine needle aspiration cytology (FNA-C) of lymph nodes, and the level of thyroglobulin in lymph node fine needle aspiration eluate (FNA-Tg) in the diagnosis of cervical lymph node metastasis of papillary thyroid carcinoma (PTC).   Methods  Firstly, CDU signs of cervical lymph nodes, FNA-C, FNA-Tg level, preoperative serum Tg level, and postoperative pathological results of patients with PTC were retrospectively analyzed and the specificity and positive prediction rate of them were also analyzed. Then, the receiver operating characteristic (ROC) curve and the optimal diagnostic threshold of FNA-Tg levels were determined. After that, the correlation between preoperative serum Tg, thyroid-stimulating hormone (TSH), serum Tg antibody (TGAB) and lymph node FNA-Tg level were analyzed.   Results   As a result, in patients with typical ultrasound signs of cervical lymph node metastasis, the diagnostic rate of FNA-Tg was 100%, which is better than CDU and FNA-C. the cortical thickness of cervical lymph nodes is uneven and is ≥ 2mm, the diagnostic rate of FNA-Tg was 88.9%. The threshold value of FNA-Tg level in lymph nodes for diagnosing cervical lymph node metastasis of PTC was 2.57 ng/ml. There was no correlation between lymph node FNA-Tg and serum Tg level, serum TGAB (P > 0.05), while there was a correlation between lymph node FNA-Tg and TSH (P < 0.05).   Conclusions  For PTC patients with typical signs of cervical lymph node metastasis showed by CDU, the combination of CDU signs, lymph node FNA-C and FNA-Tg can accurately diagnose cervical lymph node metastasis. Attention should be paid to PTC patients with atypical signs of cervical lymph node metastasis (uneven cortical thickness ≥ 2 mm) showed by CDU, Lymph node lymph node FNA-C and FNA-Tg can significantly improve the diagnostic rate and form an important basis for clinical treatment of cervical lymph node metastasis in PTC patients.

Abstract:
  Objective  Through retrospective analysis of the inconsistency of the two blood type identification results of blood samples before and after the implementation of the “comprehensive blood transfusion quality management” in our hospital, the reasons were investigated and analyzed, and improvement measures were proposed to ensure the safety of clinical blood use.   Methods  We performed a comparative analysis of the 2 blood type identification results of blood samples which were tested in the first three years (January 2015 to December 2017) and the later three years (January 2018 to December 2020) in our hospital after implementation of “Comprehensive Blood Transfusion Quality Management”   Results  From 2015 to 2020, a total of 12,023 cases of blood type identification were performed twice, and a total of 46 blood samples were identified with inconsistent results. The incidence rate was 0.038%, including 34 cases (0.061%) in the first three years and 12 cases (0.019%) in the later three years (P < 0.05). The related factors were investigated and analyzed. In the first three years after the implementation of “Comprehensive Blood Transfusion Quality Management”, the main reason was the wrong identification of patients, and the main responsibility was the nurse. In the later three years after the implementation of “Comprehensive Blood Transfusion Quality Management”, the main reason was that patients borrow other people’ s information, and the main responsibility was the patient.   Conclusion  The risk of blood transfusion can be effectively reduced by carrying out “Comprehensive Blood Transfusion Quality Management”, strictly implementing the operating procedures, and comparing the test results of two blood samples of the same patient’ s blood type and cross matching.

Abstract:
  Objective  To compare the efficacy of four methods on removal of calcium hydroxide in root canals.   Methods  Forty simulated resin root canals with 45° curvature were randomly divided into four groups. After root canal preparation, the apical foramen were sealed with glass-ionomer cement, the root canals were filled with calcium hydroxide, and the root canal orifices were sealed with hard wax. After being placed in a constant temperature water bath at 37 ℃ for 14 days, four methods including needle irrigation, Er: YAG laser irrigation, EDDY working tip irrigation and ultrasonic irrigation were used to remove the calcium hydroxide. The resin root canals before and after calcium hydroxide removal were scanned by cone-beam CT, and the scanning results were imported into Mimics software. Three-dimensional reconstruction of each root canal was performed by Mimics software, and the volume of calcium hydroxide in each root canal was calculated. The volume of calcium hydroxide was V1 before removal and V2 after removal, and the clearance rate was (V1-V2)/V1 * 100%. Rank sum test was used for statistical analysis.   Results  There was no significant difference in the initial volume of calcium hydroxide paste among the groups before removal (P > 0.05). After removal, the residual volume of calcium hydroxide paste in Er: YAG laser group was 0.1296 (0.0920, 0.1743) mm3, which was less than the other three groups, and the difference was statistically significant (P < 0.05). The reduction rate of calcium hydroxide paste was 99.63 % (99.53%, 99.70%) in Er: YAG laser group, which was higher than the other three groups, and the difference was statistically significant (P < 0.05). The reduction rates of EDDY group and ultrasonic group were 99.08% (98.85%, 99.19%) and 99.04% (98.51%, 99.15%), respectively. There was no significant difference between the two groups (P > 0.05), but they were higher than needle group 74.99% (64.43%, 88.07%) (P < 0.05), and the difference was statistically significant.   Conclusions  In this study, Er: YAG laser-activated irrigation, EDDY irrigation and ultrasonic irrigation have better removal effects on calcium hydroxide paste in root canals than traditional needle irrigation. Compared with other four methods, Er: YAG laser-activated irrigation has the highest removal efficiency, EDDY irrigation and ultrasonic irrigation have similar removal efficiency, but none of the four methods could completely remove calcium hydroxide paste from the curved root canals.

Abstract:
  Objective  To investigate the influence of opportunistic infectious pathogens on the distribution of peripheral blood T lymphocyte subsets in newly acquired AIDS patients during efficient antiretroviral therapy.   Methods  A total of 220 AIDS patients who were first diagnosed and not performed with antiviral treatment in Infectious Disease Department I of Kunming Third People's Hospital from January 1, 2019 to June 30, 2020 were collected. According to clinical diagnosis, out of 220 patients, 33 patients had AIDS combined with mycobacterium tuberculosis, 30 patients had AIDS combined with hepatitis C virus, 31 patients had AIDS with Talaromyces marneffei, 45 patients had AIDS combined with 1 pathogens, 30 patients had AIDS with 2 pathogens, and 51 patients had AIDS with 3 or more pathogens. The treatment regimen was Tenofovir disoproxil fumarate tablets + lamivudine + EFV (TDF + 3TC + EFV). Anticoagulant samples were collected before treatment, 3, 6 and 12 months after treatment. The peripheral blood T lymphocyte subsets were detected by flow cytometry. The distribution of peripheral blood T lymphocyte subsets in each group during antiviral treatment was compared and analyzed.   Results  The counts of CD3+, CD8+ and CD4+T lymphocyte in 3 groups of patients including the patients with AIDS combined with mycobacterium tuberculosis (AIDS/TB), the patients with AIDS combined with hepatitis c virus (AIDS/HCV) and the patients with AIDS combined with Talaromyces marneffei (AIDS/TM) were significantly increased after 3 months treatment, and the differences were of statistical significance (P < 0.05). As for AIDS/TM group, the CD4+T lymphocyte count increased significantly after 6 months of treatment; As for the other two groups, there was no obvious change of 3 indexes in the subsequent treatment, and the difference was statistically significant. (P > 0.05). There was no significant difference in the count of CD3+ and CD8 + T lymphocytes in the three groups after 1 year of treatment, and the difference was of no statistical significance (P > 0.05); The CD4 + T lymphocyte count in AIDS/HCV group was higher than that of the other two groups, and the difference was statistically significant (P < 0.05). The CD3+ and CD8+T lymphocyte counts increased significantly after 3 months of antiviral treatment in the group of AIDS with 1 pathogen (AIDS/1), and the difference was statistically significant (P < 0.05). There was no significant change in CD4+T lymphocyte count during the whole treatment period, and the difference was no statistically significant (P > 0.05). The CD8+T lymphocyte counts after treatment for 6 months and the CD3+ lymphocyte counts after treatment for 3 months in the group of AIDS with 2 pathogens increased significantly, and the difference was statistically significant (P < 0.05). The CD3+ and CD8+T lymphocyte counts increased significantly after 6 months of treatment in the group of AIDS with 3 or more pathogens (AIDS/≥3); The CD4+T lymphocyte count of AIDS/2 and AIDS/≥3 groups increased significantly after 3 and 6 months of treatment, and the difference was statistically significant (P < 0.05). After one year of treatment, there was no significant difference in CD3+ and CD8+T lymphocyte counts among the three groups, and the difference was no statistically significant (P > 0.05); The CD4+T lymphocyte count of AIDS/1 group was higher than that of the other two groups, and the difference was statistically significant (P < 0.05). The ratio of CD4+/CD8+ in 6 groups was less than 1.   Conclusions  After the standardized efficient antiretroviral therapy, the counts of CD3+ and CD8+T lymphocytes in the peripheral blood of AIDS patients can be restored to the same level, regardless of the type and quantity of opportunistic pathogens. The distribution level of T lymphocyte subsets in the AIDS patients before and after treatment and the type and quantity of opportunistic pathogens will affect the recovery rate and level of CD4+T lymphocyte count during treatment. Three months before the efficient antiretroviral treatment is the key period to evaluate the therapeutic effect, while CD4/CD8 is not an ideal evaluation index.

Abstract:
The goals of orthodontic treatment are balance, stability and aesthetics, an important physiological foundation for achieving the above goals is a good occlusal relationship, which includes static and dynamic occlusion. The evaluation of occlusal efficacy involves the static occlusal indicators such as overbite, overjet, midline and molar relationship at the intercuspal position (ICP), as well as the dynamic occlusion during the centric and non-centric excursions. The PAR index represents the degree of deviation from the ideal occlusion, and the occlusal alternations can be quantitatively evaluated by comparing the differences in PAR index before and after orthodontic treatment. The T-scan digital occlusal system can be used to evaluate the dynamic occlusion because of its characteristics of “force and time” correlation. In this paper, the advantages of PAR index combined with T-SCAN occlusal system in evaluating the occlusal efficacy of orthodontic treatment were reviewed.

Abstract:
Gastric cancer is the second most common malignant tumor in the world in terms of morbidity and mortality. It is a serious threat to human health.In recent years, with insulin resistance as the core of a group of metabolic disorder syndrome - the metabolic syndrome (metabolic syndrome, MetS) and the relationship between gastric cancer high-profile, a large number of studies had shown that various factors in the MetS and its complications could affect the occurrence and development of gastric cancer, the possible mechanism including hyperglycemia, obesity, insulin factors such as single or multiple factors synergy, this article aims to surrounding related research in recent years, were reviewed from aspects of the epidemiology, the pathogenesis of various metabolic factors associated with MetS and complications associated with stomach cancer.

Abstract:
  Objective  To explore the effect of cluster nursing on the curative effect of negative pressure sealing drainage (VSD) combined with myocutaneous flap transplantation in the repair of stage ⅲ and ⅳ pressure ulcer.   Methods  60 patients with stage III and IV pressure sores who underwent VSD combined with myocutaneous flap transplantation in xinkunhua Hospital of the first people’s Hospital of Yunnan Province from September 2019 to March 2021 were selected by convenient sampling method. The subjects were randomly divided into observation group and control group. The control group was given routine nursing, and the observation group was given cluster nursing on the basis of the control group. The change of wound area, tissue type and exudation were evaluated by push scale, and the healing time and treatment efficiency of the two groups were compared.   Results  After 7 days of intervention, there was no significant difference in push score between the two groups (P > 0.05). At 14 and 21 days of intervention, the push score of the observation group was lower than that of the control group (P < 0.05). There was significant difference in push score at each time point in the observation group (P < 0.05). There was no significant difference between the 14 days of intervention and the 21 days of intervention in the control group (P > 0.05); The healing time in the observation group (29.2 ± 8.6) d was lower than that in the control group (35.7 ± 13.7) d (P < 0.05); After 21 days of intervention, the effective rate of the observation group was higher than that of the control group (P< 0.05).   Conclusion  Cluster nursing for patients with stage III and IV pressure ulcer repaired by VSD combined with myocutaneous flap transplantation can effectively promote the recovery of pressure ulcer and can be popularized in clinical practice.
