Objective To assess the quality of diagnostic studies on detecting the tuberculosis antibody to diagnose tuberculosis.Methods CBM (1978 to 2006) and VIP (1994 to 2006) were searched; any author-claimed diagnostic studies which used the dot immunogold filtration assay (DIGFA) to detect the tuberculosis antibody and to diagnose tuberculosis were included. The Quality Assessment of Diagnostic Accuracy Studies (QUADAS) was used to assess the quality of included diagnostic studies by two reviewers independently.Results Thirty-eight papers were included and assessed. We found that most of the quality items were not met with QUADAS. Most papers adopted the retrospective diagnostic case-control design. Thirty-one papers did not describe the selection criteria clearly, 18 did not describe whether all the included patients were verified by using a reference standard of diagnosis, 36 did not describe whether the index test results were interpreted without knowledge of the results of the reference standard, 37 did not report the uninterpretable/intermediate test results, and 34 did not report the withdrawals from the study.Conclusion There are few high quality studies on using DIGFA to detect tuberculosis antibody to diagnose tuberculosis.
Objective
To investigate the influence of self-care and self-efficacy intervention on the quality of life of patients undergoing chemotherapy after surgery for gastric cancer.
Methods
Sixty-four patients undergoing chemotherapy after gastric cancer surgery between July 2014 and February 2015 were selected as the study subjects. According the sequence of admission, they were divided into intervention group (n=34) and control group (n=30). Patients in the control group accepted conventional care, while those in the intervention group received self-efficacy and self-care interventions. The scores of General Self-efficacy Scale (GCES), Exercise of Self-care Agency (ESCA), and Quality of Life Instruments for Cancer Patients-Stomach Cancer (QLICP-ST) were compared between the two groups before and after intervention.
Results
After intervention, GCES scores of the intervention group and the control group were respectively (30.08±4.21) and (20.78±4.58) points; the total scores of ESCA were respectively (132.30±14.81) and (92.45±13.23) points; and the total scores of QLICP-ST were respectively (75.96±9.41) and (56.77±10.32) points. All the above differences between the two groups were significant (P<0.05).
Conclusion
Self-care and self-efficacy intervention can improve self-care ability and self-efficacy, and improve the quality of life of patients undergoing chemotherapy after gastric cancer surgery.

Objective To review the research progress of the current methods of inducing bone marrow mesenchymal stem cells (BMSCs) to chondrogenic differentiation in vitro so as to provide references for researches in cartilage tissue engineering. Methods Various methods of inducing BMSCs differentiation into the chondrogenic l ineage in vitro inrecent years were extensively reviewed and analyzed. Results Adding exogenous growth factors is still the mainly methodof inducing BMSCs differentiation into the chondrogenic l ineage; among the members, transforming growth factor β (TGF-β) family is recognized as the most important chondrogenic induction factor. Other important inducing factors include various chemical factors, physical factors, transgenic methods, and the microenvironmental induction. But the problems of low inducing efficiency and unstable inducing effects still exist. Conclusion The progress of chondrogenic induction of BMSCs promotes its util ization in cartilage tissue engineering. Further researches are needed for establ ishing more efficient, simpler, and safer inducing methods.
ObjectiveConduct a scoping review of medical student competency assessment research to provide a reference for constructing a scientific, practical, and feasible assessment system. MethodsThe search was conducted in CNKI, SinoMed, WanFang Data, PubMed, Web of Science and Embase databases. The time limit was set from the inception to June 2025. A scope review was conducted based on Arksey and O’Malley’s framework of scope definition review methods. ResultsA total of 31 studies were included, involving 13 theoretical, 6 empirical, and 12 mixed-methods. These studies reported on mainstream competency assessment methods in medical education, such as the objective structured clinical examination, 360-degree evaluation, mini-clinical assessment (MCA), multiple-choice questions (MCQs), and direct observation of procedural skills. Studies on competency model construction primarily used the Miller pyramid, Bloom’s taxonomy of educational objectives, and the current physician competency consensus as core theoretical frameworks. Mixed research methods, such as literature analysis, behavioral event interviews, the Delphi method, and questionnaire surveys, were frequently employed. Domestic competency models primarily focused on "knowledge, skills, and professionalism" as core indicator elements, with the five-point Likert scale being the predominant format for questionnaire items (8 items, 57.1%). Although research reliability validation was relatively well-established, More than half of the studies (7 items, 53.8%) did not report validity metrics. Conclusion While theoretical foundations in competency research are well-established and modeling methodologies are diverse, current assessment methods face limitations, and a lack of uniformity persists in the core elements of competency models. Competency models developed domestically and internationally exhibit significant differences in dimension categorization and item quantity.
Objective To discuss the diagnosis, treatment, and follow-up visit mode of thyroid carcinoma showing thymus-like elements (CASTLE). Mothods For a systematic review of a case with CASTLE, the domestic and overseas literature was searched to analyze final diagnosis, treatment and follow-up visit indexes of that case. Results For CASTLE, the pathology combined with immunohistochemistry was the only method for final diagnosis, the operation was the main treatment, and the ultrasound as well as the computed tomography (CT) could be the follow-up visiting indexes. Conclusion CASTLE is a special kind of thyroid carcinoma, which is different from differentiated thyroid carcinoma in diagnosis, treatment and follow-up visit.
ObjectiveTo investigate the status of roxadustat in patients undergoing maintenance peritoneal dialysis and analyze the factors affecting drug compliance. MethodsPatients with renal anemia undergoing maintenance peritoneal dialysis in West China Hospital of Sichuan University from July 2020 to March 2021 were selected. All patients took roxadustat orally. According to the medication compliance, the patients were divided into good compliance group and poor compliance group. The general information questionnaire and Morisky Medication Adherence Scale-8 (MMAS-8) were used to investigate and analyze the included patients, and their clinical examination indexes were collected. ResultsA total of 100 patients were included, Including 39 cases (39%) in the good compliance group and 61 cases (61%) in the poor compliance group. The average score of medication compliance of roxadustat was 5.19±1.72. Logistic regression analysis showed that drug cognition [odds ratio (OR)=0.099, 95% confidence interval (CI) (0.027, 0.365), P=0.001], medication troubles/complex protocol [OR=5.330, 95%CI (1.567, 18.132), P=0.007], and adverse drug reactions [OR=5.453, 95%CI (1.619, 18.368), P=0.006] were factors affecting patient compliance. Hemoglobin in the good compliance group was lower than that in the poor compliance group (Z=?2.259, P=0.024); there was no significant difference in other clinical examination indexes (P>0.05). ConclusionsThe overall compliance of oral roxadustat in maintenance peritoneal dialysis patients is poor, and the corresponding follow-up management system should be improved. Nurses should provide comprehensive and systematic medication guidance to patients, encourage them to fully understand the clinical manifestations, treatment schemes and prognosis of renal anemia, clarify the time, dose, possible adverse reactions and mitigation methods of roxadustat, etc., and help them to treat the disease with correct cognition and attitude, so as to improve their drug compliance.
At present, the potential hazards of infrasound on heart health have been identified in previous studies, but a comprehensive review of its mechanisms is still lacking. Therefore, this paper reviews the direct and indirect effects of infrasound on cardiac function and explores the mechanisms by which it may induce cardiac abnormalities. Additionally, in order to further study infrasound waves and take effective preventive measures, this paper reviews the mechanisms of cardiac cell damage caused by infrasound exposure, including alterations in cell membrane structure, modulation of electrophysiological properties, and the biological effects triggered by neuroendocrine pathways, and assesses the impact of infrasound exposure on public health.
ObjectiveTo evaluate the relationship between the expression of alpha fetoprotein (AFP) and chemoresistance in hepatocellular carcinoma.MethodsHepatocellular carcinoma was screened from liver tumor tissue samples, which was obtained by puncture before transcatheter arterial chemoembolization (TACE). Immuno-histochemical staining was used to detect the expression of AFP in HCC tissues and the effect of AFP expression in HCC on the effect of chemotherapy was analyzed.ResultsA total of 62 patients met the inclusion criteria, of which 36 were in the chemotherapy resistant group and 26 in the chemotherapy sensitive group. There were 42 patients with positive expression of AFP in tumor tissues (including 29 patients with chemoresistance) and 20 patients with negative expression of AFP in tumor tissues (including 7 patients with chemoresistance). There were no significant difference between the two groups in sex, age, tumor differentiation, Child-Pugh classification of liver function, tumor size, tumor site and hepatitis (P>0.05). In elevated serum AFP level, tumor single, and with portal vein tumor thrombus (PVTT), the proportion of patients in the chemosensitivity group were significantly lower than that in the chemosensitivity group (P<0.05). The results of logistic multivariate regression analysis showed that positive expression of AFP ［OR=0.280, 95%CI (0.092, 0.950), P=0.045］ and PVTT ［OR=0.026, 95%CI (0.004, 0.322), P=0.005］ were independent risk factors for chemotherapeutic resistance in hepatocellular carcinoma.ConclusionAFP positive expression in liver tumor tissues and PVTT are useful indicators of resistance to chemotherapy.
