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 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.

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 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.
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.
ObjectivesTo introduce the formulating methods and implementing steps of search strategy of systematic reviews (SRs)/meta-analysis (MAs) of animal experiments, so as to provide a reference for domestic related researchers, and promote the development and implementation of high quality SRs/MAs of animal experiments in China. MethodsPubMed, EMbase and CNKI databases were searched online to retrieve studies on the search strategy of SRs/ MAs of animal experiments from inception to October 2017. A descriptive analysis was then conducted using the evidence-based medicine theory and method.ResultsA total of 5 studies were included. The 5 basic steps on how to design and carry out comprehensive search strategies to identify potentially relevant animal experiments on a specific research question were as follow: 1) Formulate research question; 2) Identify appropriate databases and sources of studies; 3) Transform research question into search strategy; 4) Collect search results and remove duplicates; 5) Identify potentially relevant papers. The report of search strategy needs to state its search method and search results clearly.ConclusionThese 5 steps can provide an effective method, which will assist researchers in performing a comprehensive literature search.
ObjectivesTo survey the current research situation, methodological and reporting quality of the systematic review/meta-analysis (SRs/MAs) of animal studies.MethodsPubMed, EMbase, BIOSIS Previews, CNKI, WanFang Data, CBM and VIP databases were searched to collect SRs/MAs of animal studies from inception to June 2016. Two reviewers independently screened literature, extracted data, a descriptive analysis was then conducted.ResultsA total of 609 SRs/MAs of animal studies were included, which were from 27 countries and published in 526 journals. Merely 36.8% (224/609) studies assessed the risk of bias in the original animal experiments. Less than 50% studies reported the method of literature selection (41.9%, 255/609), data abstraction (32.0%, 195/609) and study characteristics (41.2%, 251/609).ConclusionsThe published SRs/MAs of animal studies is poor in both methodological and reporting quality. Thus, we hope to improve awareness and actual use rates of these guidelines by basic medical researchers and journal editors, thereby improving the quality of animal experimental methods and reporting standards.
