Objective:To revise the 5C Psychological Antecedents of Vaccination Scale(5C Scale),and to examine its validity and reliability.Methods:The Chinese version of the adapted scale was formed using the Chi-nese-English back-translation method,along with expert evaluation and interview results.A questionnaire survey was administered to 1 035 residents.The effective recovery results were randomly divided into 2 groups and tested for exploratory and confirmatory factor analysis.After 2 weeks,230 residents were re-tested.The neuroticism sub-scale of the Chinese Big Five Personality Inventory Brief Version(CBF-PI-B)was used to test the criterion-related validity.Results:The 5C Scale was revised to add a new dimension of confusion,forming the 6C Psychological An-tecedents of Vaccination Scale(6C Scale)with 18 items,6 factors including confidence,complacency,constraint,calculation,collective responsibility and confusion,which accumulatively explained 67.92％of the total vari-ance.And the six-factor structural model fits well(x2/df=1.72,RMSEA=0.04,CFI=0.97,TLI=0.96,NFI=0.92,IFI=0.97).The total scores of the confusion dimension exhibited a positive association with the total scores of CBF-PI-B neuroticism subscale(ICC=0.54,P＜0.001).The Cronbach α coefficients of the 6 factors ranged from 0.68 to 0.77,and the retest reliabilities(ICC)ranged from 0.51 to 0.82.Conclusion:The 6C Psychological Antecedents of Vaccination Scale(6C Scale)revised in this study exhibits good validity and reliability in assessing residents'psychological antecedents related to vaccination.

Objective To identify and analyze the digital supervision issues of cross-province medical treatment in China,and propose countermeasures and suggestions.Methods Using literature research,expert interviews,and questionnaire surveys,from January 29,to February 132023,managers,staff from remote departments of medi-cal insurance bureau and scholar in the field of medical insurance in H province were selected.Principa l component analysis was used to extract questions,and based on the extraction results,a multiple logistic regression model to explore that have a significant impact on the digital supervision of cross-province direct settlement of medical treat-ment.Results The problems of digital supervision of direct settlement for medical treatment across provinces and re-gions in China can be divided into 7 categories,with a cumulative variance contribution rate of 63.17%.The connec-tion of digital regulatory systems,audit rules and early warning issues,as well as the lack of legal systems and defi-nitions have a significant impact on regulatory effectiveness(P＜0.05).Conclusion Incomplete construction of the digital supervision system between the place of insurance participation,and inadequate legal and institutional sateguards for the digital supervision of the direct settlement of cross-provincial cross-district medical consultations.Therefore,strengthening the basic construction of the digital supervision system for cross provincial and cross regional medical direct settlement,and improving the legal system for cross provincial and cross regional medical direct settle-ment digital supervision,have important guiding significance for the digital supervision of cross provincial and cross regional medical direct settlement in China.

Objective To explore the predictive value of gait and balance on the frailty in community-dwelling older adults aged 65 years and older in Shanghai. Methods A total of 414 community-dwelling older adults aged 65 years or older were recruited from Shanghai,from De-cember,2022 to April,2023.They were investigated with Fried's Frailty Phenotype Scale,Timed Up and Go Test(TUGT),one leg standing test(OLST)and self-designed questionnaire.The factors related to frailty were ana-lyzed using multivariate Logistic regression. Results The prevalence of pre-frailty and frailty were 62.8%and 10.9%,respectively.Living in rural residence,older age,low income,smoking,sedentary lifestyle and no regular exercise were the risk factors for frailty among com-munity-dwelling older adults.Time of TUGT increased,and time of closed eyes OLST descreased respectively in the frail older adults(P<0.05).The area under curve was 0.846(95%CI 0.808 to 0.884,P<0.001)as prediction for frailty using the combination of TUGT and closed eye OLST,with a sensitivity of 0.726 and a specificity of 0.817 at the optimal threshold. Conclusion Gait and balance may be a valuable predictor of frailty in community-dwelling older adults in Shanghai.

The acute myeloid leukemia and myelodysplastic syndromes are common myeloid neoplasms for which allogeneic hematopoietic stem cell transplantation is one of the main curative therapies. In high-risk patients, the relapse rate can be more than 40%, and patients with post-transplantation relapses have a very poor prognosis, so preventing relapse after transplantation is crucial. The maintenance therapy is a group of interventions to prevent relapse when morphological, molecular biological and cytogenetic results are constantly negative after transplantation. Currently, the commonly used maintenance therapy is the application of demethylating drugs, targeted drugs, etc., but their necessity, medicine plan, adverse effects, multi-drug combinations, and other aspects need to be studied urgently. This article will systematically describe the progress of post-transplantation maintenance therapy for high-risk myeloid neoplasms based on drug classification.

Objective     To compare the clinical efficacy of subxiphoid video-assisted thoracoscopic surgery (XVATS) and conventional intercostal VATS (CVATS) extended thymectomy for myasthenia gravis (MG). Methods    The clinical data of MG patients who underwent extended thymectomy in the Department of Thoracic Surgery of Xuzhou Central Hospital from October 2016 to October 2021 and finished the follow-up were retrospectively reviewed. They were divided into an XVATS group and a CVATS group according to the procedure. The perioperative variables and clinical efficacy of the two groups were compared. Results    A total of 84 patients were collected, including 43 males and 41 females, with a mean age of 52.3 years. There were 41 patients in the XVATS group and 43 patients in the CVATS group. There was no mortality, cardiopulmonary thrombosis, prolonged air leak, or mediastinal infection. Additionally, the CVATS group recorded 5 (11.6%) patients of conversion to open thoracotomy, 1 (2.3%) patient of postoperative MG crisis, 1 (2.3%) patient of bleeding in thorax, and 1 (2.3%) patient of chylothorax. The operation time (127.4±50.4 min vs. 122.9±38.6 min), intraoperative bleeding [46.9 (25.7, 79.2) mL vs. 45.7 (21.9, 92.1) mL], incidence of complications [0 vs. 7.0% (3/43)], chest tube duration (4.3±1.9 d vs. 4.8±2.8 d), follow-up time (19.1±8.5 months vs. 22.5±13.7 months), the proportion of residual mediastinal fat tissue [12.2% (5/41) vs. 4.7% (2/43)], and total MG remission rate [29.3% (12/41) vs. 51.2% (22/43)] were not statistically different between the two groups (P>0.05). However, the two groups showed  significantly different incidence of conversion to open thoracotomy [0 vs. 11.6% (5/43), P=0.024], postoperative hospital stay time (8.2±3.3 d vs. 11.4±5.8 d, P=0.003) and total drainage volume [396.7 (173.8, 542.5) mL vs. 218.8 (102.1, 430.0) mL, P=0.038]. Conclusion    XVATS extended thymectomy is technically safe and feasible; however, more evidence is warranted before the recommendation of this approach for the treatment of MG.

Objective:To explore the clinical characteristics, diagnosis and treatment of acute leukemia patients during pregnancy.Methods:The clinical data of 16 cases with acute leukemia during pregnancy from January 2009 to December 2018 in the First Affiliated Hospital of USTC were retrospectively analyzed. The diagnosis and treatment regimens, pregnancy outcome, the early fetus and survival status of patients were also analyzed.Results:All 16 leukemia cases were confirmedly diagnosed and classified by bone marrow puncture, including 13 cases of acute myeloid leukemia (5 cases of non-acute promyelocytic leukemia and 8 cases of acute promyelocytic leukemia) and 3 cases of acute lymphoblastic leukemia. At the time of confirmed diagnosis, 6 patients were in first trimester, 6 cases in second trimester and 4 cases in late trimester. As for pregnancy outcome, 1 patient had natural birthing, 5 patients underwent cesarean operation, 9 patients underwent artificial abortion and 1 patient had spontaneous abortion. Chemotherapy was performed in 15 patients during pregnancy, 11 patients received chemotherapy for treatment of primary disease after pregnancy, 3 patients died during the treatment. During the follow-up of 13 cases, 8 patients survived and 5 patients lost follow-up.Conclusions:Early diagnosis of acute leukemia during pregnancy is very important. Bone marrow puncture should be performed timely to make clear diagnosis when blood routine result is abnormal during antenatal care. Multidisciplinary consultation should be initiated in time, and the best treatment plan should be worked out to guard against serious complications during pregnancy.

Objective:The aim of this study was to study the characteristics of neoplasm invasion type in ovary of two orthotopic models established with human epithelial ovarian cancer solid tumor tissue slices and human ovarian carcinoma cell line OVCAR-3 in nude mice and human epithelial ovarian cancer.Methods:Tumor tissues and cell line OVCAR-3 of human epithelial ovarian cancer were grown in subcutaneous tissue and the subcutaneous tumor source was fetched and inoculated in ovarian capsule of nude mice to establish the orthotopic implantation model. The neoplasm invasion type in the two kinds of models were observed. The neoplasm invasion types were also analyzed by pathological examination in 54 cases of International Federation of Gynecology and Obstetrics (FIGO) stageⅠ-Ⅱepithelial ovarian cancer.Results:Three neoplasm invasion types were found as follows: type of pseudocapsule, type of pseudocapsule invasion, type of pseudocapsule penetration. Pseudocapsule rate in the solid tumor slices group (18.2%) were lower than those in the cell line group (42.3%) ( P<0.05), while the pseudocapsule penetration rate in the solid tumor slices (50.0%) were higher than those in the cell line group (23.1%) ( P<0.05). No difference was found of pseudocapsule invasion rate between two groups ( P>0.05). Neoplasm invasion type in ovary changed with tumor planting time. High proportion of pseudocapsule type was found at the beginning of tumor planting, and the pseudocapsule penetration rate raised with tumor planting time increased. High proportion of pseudocapsule type was also found in patients with FIGO stageⅠepithelial ovarian cancer, and pseudocapsule penetration rate increased in those with FIGO stageⅡ. No difference in neoplasm invasion type was found between two kinds of pathological types ( P>0.05). Conclusions:There are differences between the two kinds of orthotopic models established with human epithelial ovarian cancer solid tumor tissue slices and human ovarian carcinoma cell line OVCAR-3. Compared to the solid tumor slices model, the cell line model is more stable for the follow-up study. The proportion of three neoplasm invasion types in ovary were more balanced in 8 weeks after tumor planting, and 8 weeks after tumor planting is the best start time for the follow-up experiment.

Zinc levels are high in pancreatic β-cells, and zinc is involved in the synthesis, processing and secretion of insulin in these cells. However, precisely how cellular zinc homeostasis is regulated in pancreatic β-cells is poorly understood. By screening the expression of 14 Slc39a metal importer family member genes, we found that the zinc transporter Slc39a5 is significantly down-regulated in pancreatic β-cells in diabetic db/db mice, obese ob/ob mice and high-fat diet-fed mice. Moreover, β-cell-specific Slc39a5 knockout mice have impaired insulin secretion. In addition, Slc39a5-deficient pancreatic islets have reduced glucose tolerance accompanied by reduced expression of Pgc-1α and its downstream target gene Glut2. The down-regulation of Glut2 in Slc39a5-deficient islets was rescued using agonists of Sirt1, Pgc-1α and Ppar-γ. At the mechanistic level, we found that Slc39a5-mediated zinc influx induces Glut2 expression via Sirt1-mediated Pgc-1α activation. These findings suggest that Slc39a5 may serve as a possible therapeutic target for diabetes-related conditions.

Objective To explore the clinical effect of suprapubic small cut method combined with transurethral resection prostate(TURP) on the treatment of benign prostatic hyperplasia(BPH) complicated with bladder stones.Methods Sixty patients with BPH complicated with bladder stones ≥ 3 cm in the People's Hospital of Futian Affiliated to Guangdong Medical College from January 2013 to September 2014 were selected as the study group,and another 60 patients with BPH complicated with bladder stones＜3 cm during the same period were selected as the control group.The cases in the study group were treated with suprapubic small cut method combined with TURP,and the cases in control group were treated with transurethral method combined with TURP.The intraoperative indicators (including the time used for crushed stone,total operation time,blood loss,conversion to laparotomy,blood transfusion and bladder perforation),residual bladder stones and complications of postoperative were compared.Results The operations of the two groups of patients were successfully,and there was no conversion to laparotomy and either bladder perforation.The stone removal time and total operative time of patients of the study group were shorter than of the control group,the difference was statistically significant((12.20±3.55) min vs.(24.05±7.68) min,(62.31± 10.49) min vs.(82.46± 16.75)min;t =10.849,7.897;P＜0.001).The intraoperative blood loss and the cases of blood transfusion of patients of the study group were less than the control group,but the prevalence of urinary tract infection were higher(6vs.4),but the difference was not statistically significant(P＞0.05).Residual stones were more commonly in the control group than in the study group (study group:0,control group:6 cases),the difference was statistically significant(x2 =6.316,P=0.012).Conclusion BPH complicated with bladder stones can be treated by the suprapubic small cut method combined with TURP or transurethral method combined with TURP,but suprapubic small cut method combined with TURP is safer and more effective,which is worthy of popularization and application in clinic.

OBJECTIVETo investigate the levels and functions of CD4(+)CD25(+) regulatory T cells and specific transcription factor Foxp3 and Th17 cells related cytokine in peripheral blood mononuclear cells (PBMC) and renal tissues, and explore their roles in pathogenesis of Henoch-Schonlein purpura nephropathy (HSPN) in children.

METHODFrom March, 2011 to March, 2013, 30 cases of HSPN children underwent renal biopsy and were treated in Guiyang Children's Hospital were enrolled into this study. Ten healthy children who underwent health check up were enrolled as blood sample control group. The normal kidney tissue specimens were taken from 5 children who underwent surgery for urologic disorders were used as renal sample control group. The circulating proportions of CD4(+)CD25(+) regulatory T cells in PBMC of 30 cases of HSPN children and 10 cases of control group were determined by flow cytometry, respectively.Reverse transcription-polymerase chain reaction (RT-PCR) were used to analyze the mRNA expressions of IL-17, IL-1β and Foxp3 in PBMC. The expression of IL-17 and IL-1β in renal tissue of HSPN and control group were measured by immunohistochemistry. CD4(+)CD25(+) regulatory T cells, Foxp3, IL-17, IL-1β expression were analyzed and compared in HSPN group and control groups respectively.

RESULTThirty cases of HSPN pathological classification were as follows: type I was found in 0 case; type II in 9 cases; type III in 16 cases; type IV in 5 cases; type V in 0 case. The circulating proportions of CD4(+)CD25(+)/CD4(+)T cells and the CD4(+)CD25(+)Foxp3(+)Treg/CD4(+)T cells level were (5.84 ± 0.78)%, (1.01 ± 0.46) % in HSPN groups were substantially lower than those in control group. All these two differences had statistical significance (t = 27.200, 33.260, P < 0.05). The mRNA levels of IL-17, IL-1β in HSPN groups (0.86 ± 0.01,0.71 ± 0.01) were higher than those in control group (t = 25.000, 31.840, all P < 0.05). Foxp3 mRNA expression in HSPN groups (0.24 ± 0.02) were significantly lower than those in control group (t = 21.690, P < 0.05). Protein expression of IL-17 and IL-1β in renal tissues of HSPN children (13.31 ± 0.54, 11.56 ± 0.28) were significantly stronger than those in the control group (t = 27.6, 14.0, all P < 0.01). The highest level of protein expression of IL-17 and IL-1β in renal biopsy of HSPN was in type IV (IV>III>II, F = 545.800, 262.500, all P < 0.01).

CONCLUSIONThe disorder of quantity and function of CD4(+)CD25(+) regulatory T cells, and increase in levels of IL-17, IL-1β (cytokine related to Th17 cells) may play important roles in pathogenesis of HSPN in children; increased protein expression of IL-17, IL-1β in renal tissue may contribute to the development of renal pathological damage in HSPN children.
