ObjectiveTo analyze the clinical manifestations and laboratory test results of 357 cases of first-diagnosed systemic lupus erythematosus (SLE), and provide a reference for SLE diagnosis. MethodsA total of 357 SLE patients on their first diagnosis were collected from 2008 to 2012 in our hospital, and the clinical manifestations and laboratory findings of these patients were recorded and analyzed. ResultsAll the patients had different clinical manifestations and serious multi-system damages. In these patients, there were 59.1% (211 cases) involved with arthritis, followed by rash and kidney damage. The complement declined in 75.9% of the patients according to the results of immunological tests. In the ENA spectrum inspection, anti-SSA antibody had the highest positive rate (51.3%), followed by anti-u1RNP antibody (44.0%), anti-dsDNA antibody and anti-nucleosome antibody. The first onset of most clinical manifestations was rash (43.4%), followed by arthritis and lower extremity edema; a few patients had headache or numbness as the first symptom. ConclusionSLE patients have diverse clinical manifestations, serious multi-system damages and outstanding heterogeneity, which is inconsistent with foreign reports.
Abstract: Objective To analyze the characteristics of pathogens isolated from patients with lung cancer after surgery, and provide instructions for the prevention and treatment of postoperative infection. Methods A retrospective investigation of the pathogenic microbiology data of 159 patients（142 males and 17 females with average age at 61.8±9.6 years) with lung cancer after surgery in West China Hospital from January 2009 to December 2011 was performed.We got the specimen from the patients by routine methods, identified the pathogens, and conducted drug susceptibility tests in vitro. Results The pathogens were mainly isolated from sputum of the patients （90.6%, 155/171）. Canidia albicans（25.7%, 44/171）, Klebsiella pneumonia（15.2%, 26/171）, Acinetobacter calcoaceticus-A. baumannii（13.4%, 23/171）and Pseudomonas aeruginosa（8.2%, 14/171） were the predominant species. Among A. calcoaceticus-A. baumannii isolates, 39.1%（9/23） of them were multidrug resistant strains. And 23.1%（6/26）of K. pneumonia isolates produced extended spectrum beta-lactamases. P. aeruginosa isolates showed high in vitro susceptibility to the antibacterial agents. Conclusion Pathogens are mainly isolated from sputum of patients after surgery for lung cancer. Canidia albicans and gram-negative bacilli are predominant isolates and should be the major targets for the prevention and treatment of postoperative infection.
ObjectiveTo understand the current state of medical graduate student labor education in the new era and its effectiveness, to explore the mechanism by which labor education affects labor practices, and to identify intervention points for improving labor education. MethodsA questionnaire survey was conducted from July 3 to 13, 2022, on the labor education of 216 medical graduate students from 10 double-first-class universities. The relationship between labor education, labor awareness, labor ability, and labor practices was analyzed. ResultsDescriptive analysis results showed that medical graduate students received little labor education. The structural equation model results showed that labor education positively impacted labor awareness (γ=0.712) and labor ability (γ=0.755), and labor awareness and labor ability positively impacted labor practices (γ=0.400, γ=0.635), indicating that labor education has a positive impact on labor practices. ConclusionTo improve the weak state of medical graduate student labor education, it is necessary to increase related training and courses, enrich the types and content of labor education, strengthen the assessment mechanism of labor education, and strengthen the responsibilities of instructors.
ObjectiveSystemic lupus erythematosus (SLE) patients from a SLE family with homogeneity can provide experimental basis for individualized diagnosis and treatment by studying the characteristics of laboratory tests and symptoms. MethodsLaboratory tests were analyzed for three SLE patients in the family, and set up the screen model by three laboratory tests (anitnuclear antibody positive, rheumatoid factor positive and IgE positive, ANA+RF+IgE+). All SLE cases were screened from latest four years as SLE subtype patients (named "similar family SLE patients"), then the family laboratory tests and clinical characteristics were analyzed. ResultsA total of 55 patients (6.27%) were screened as similar family SLE patients from individual SLE patients according to model from 877 cases. The laboratory tests of similar family SLE patients including creatinine, WBC, CRP were significant lower than other SLE patients (P < 0.05), but significant higher for the IgG, positive rate of anti-SSA and anti-SSB (P < 0.05), and the alopecia and skin rashes were more common in similar family SLE patients than other SLE patients. ConclusionsThe ANA+RF+IgE+ SLE patients are of lower inflammatory state and kidney involvement; Clinical symptom is priority to alopecia and skin rashes.
ObjectiveTo summarize the significance of laboratory examinations in diagnosis of ulcerative colitis (UC). MethodsLiteratures at home and abroad were searched to review the clinical significance of laboratory examinations indexes in diagnosis of UC. ResultsAnti-neutrophilcytoplasmicantibodies (ANCA) had some value in diagnosis of UC, but it was limited in evaluation of UC in active patients. The positive rate of anti-intestinal goblet cell antibody (GAB) in patients with UC was higher than that of patients with Crohn's disease (CD), so it could be used as identification indexes of the two diseases, but it could not reflect the severity of the disease. Anti-saccharomyces cerevisiae antibodies (ASCA) and anti-pancreatic antibody (PAB) were mainly used in the differential diagnosis of UC and CD, but they had no significant advantages in diagnosis of UC. Fecal calprotectin (FCP) played a positive role in evaluation of recurrence and activity in UC. Although lactoferrin, M2-pyruvate kinase (M2-PK), and S100A12 were not as effective as FCP, but if combined with related indicators, they were also important. ConclusionsOf the relevant indexes of laboratory examination in the diagnosis of UC, FCP plays an importent role in the evaluation of recurrence and activity of UC.
ObjectiveTo systematically review the clinical efficacy and safety of glucocorticoids, acetaminophen and antimicrobial drugs in the treatment of intrapartum fever in labor analgesia. MethodsThe PubMed, Embase, Cochrane Library, Web of Science, CBM, VIP, and CNKI databases were electronically searched to collect randomized controlled trials (RCTs) of glucocorticoids, acetaminophen, and antimicrobial drugs for intrapartum fever in labor analgesia from inception to June 30, 2023. Two reviewers independently screened the literature, extracted data, and evaluated the risk of bias of the included literature. Meta-analysis was then performed by using RevMan 5.4 software. ResultsA total of 10 RCTs involving 1 337 women were included. Meta-analysis showed that the use of glucocorticoids reduced the incidence of intrapartum fever in women with labor analgesia compared with the control group (OR=0.52, 95%CI 0.33 to 0.82, P<0.01). But there was no statistically significant difference between acetaminophen or antimicrobial drugs and the control group. ConclusionCurrent evidence shows that the use of glucocorticoids can reduce the incidence of intrapartum fever in labor analgesia, but the use of acetaminophen and antimicrobial drugs cannot reduce the incidence of intrapartum fever. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
Objective To evaluate the diagnostic value of creatinine, as an indicator of glomerular filtration function injury. Methods MEDLINE, EMBASE and CBM-disc were searched from 1993 to 2003. Thirty four articles that described biomedical markers to indicate glomerular filtration function injury were selected according to specified inclusion criteria. These articles were evaluated systematically using SPSS, EXCEL, and RevMan software. Results The odds ratios of creatinine was 24.23. Areas under summarized receiver operator characteristic curve were 0.871. Selected articles were divided to groups for analysis according to diagnostic standards, such as inulin, iohexol, 125I-iothalamate, 51Cr-EDTA, 99mTc-DTPA and sodium thiosulfate. Inter-group analysis of creatinine was not statistically different (P=0.32). Intra-group analysis of inulin, 51Cr-EDTA, 99mTc-DTPA, and iohexol was not statistically different, P value were 0.61, 0.50, 0.36, 0.32, respectively. Intra-group analysis of 125I-iothalamate was statistically different (P=0.02). Selected articles were sub-grouped according to different analytic techniques of creatinine. Intra-group analysis by the Jaffe method was statistically different (P=0.03), intra-group analysis of enzymatic method was not statistically different (P=0.22). Conclusion The diagnostic value of creatinine was not qualified enough to indicate glomerular filtration function injury. Enzymatic methods are recommended to measure creatinine. Inulin or 51Cr-EDTA is suggusted to measure glomerular filtration rate in investigation of creatinine，and feedforward cohort is recommended to apply.
