Objective To evaluate the respective or synergistic value of cytoplasmic tryptophan-tRNA ligase(WARS1/SYWC)and adenosine deaminase(ADA)in diagnosing tuberculous pleural effusion(TPE).Methods A retrospective analysis was conducted on 120 patients with pleural effusion(64 cases of TPE,56 cases of non-TPE)admitted to the First Affiliated Hospital of Jinan University and its affiliated Shunde Hospital from January 2020 to December 2024.Pleural fluid SYWC levels were identified using enzyme-linked immunosorbent assay(ELISA).Univariate and multivariate logistic regression analyses were performed to identify diagnostic predictors,while receiver operating characteristic(ROC)curves were plotted to assess the diagnostic perfor-mance of individual and combined biomarkers.Results Compared to the non-TPE group,TPE group exhibited significantly younger age,lower pleural CEA,less serum CEA,and lower neutrophil-to-lymphocyte ratio(NLR),but significantly higher levels of pleural ADA,total protein,SYWC,and serum CRP(all P<0.05).Univariate analysis identified age,pleural CEA,carbohydrate antigen 199,ADA,SYWC,serum CEA,and NLR as potential predictors.Multivariate analysis confirmed pleural ADA(OR=1.064,95%CI:1.017～1.228)and SYWC(OR=6.695,95%CI:2.794～16.04)as independent diagnostic factors.At optimal cutoffs,SYWC(16.94 μg/L)demonstrated a sensitivity of 71.80%and specificity of 98.21%,while ADA(36.5 U/L)showed a sensitivity of 93.75%and a specificity of 89.29%.Combined detection increased the sensitivity to 95.56%,the specificity to 98.0%,and the accuracy to 97.87%.ROC analysis revealed an AUC of 0.973(95%CI:0.943～1.000)for the combination,outperforming ADA(0.897)and SYWC(0.938)alone.Conclusion The combi-nation of SYWC and ADA notably enhances diagnostic efficacy for TPE,providing high sensitivity and specificity as a reliable tool for clinical differentiation.

Objective To explore the anxiety status and influencing factors in school-age children with recurrent Henoch-Sch?nlein purpura(HSP).Methods A total of 158 school-age children with recurrent HSP were selected as the study subjects.The Screen for Child Anxiety Related Emotional Disorders(SCARED)was used to assess the anxiety status of the children.Based on the assessment results,the 158 children were divided into anxiety group and non-anxiety group.Univariate and multi-variate logistic regression analyses were employed to screen for the influencing factors of anxiety occur-rence.A logistic regression model was constructed,and the Hosmer-Lemeshow test was used to evalu-ate the model's goodness-of-fit.Results Among the 158 children,43 presented anxiety,with an anx-iety incidence rate of 27.22％(43/158).There were significant differences between the anxiety and non-anxiety groups in terms of age,neurotic personality traits,purpura location,the number of purpura recurrences,family care level,educational level of the primary caregiver,monthly per capita household income,and whether the primary caregiver had anxiety or depression(P＜0.05).Multivariate logistic regression analysis revealed that age ≥10 years(OR=7.192,95％CI,2.450 to 21.114,P＜0.001),neurotic personality traits(OR=5.202,95％CI,1.486 to 18.208,P=0.010),purpura located on the face(OR=5.648,95％CI,1.606 to 19.861,P=0.007),the number of purpura recurrences ≥2 times(OR=5.017,95％CI,1.753 to 14.361,P=0.003),a general family care level(OR=3.809,95％CI,1.153 to 12.579,P=0.028),the primary caregiver having an educational level below junior high school(OR=3.005,95％CI,1.051 to 8.592,P=0.040),the primary care-giver having anxiety(OR=6.484,95％CI,2.140 to 19.647,P=0.001),and the primary care-giver having depression(OR=9.327,95％CI,2.473 to 35.172,P=0.001)were independent risk factors for anxiety occurrence in school-age children with recurrent HSP.A logistic regression prediction model was constructed based on the above risk factors and their regression coefficients.The Hosmer-Lemeshow test results indicated a good model fit(x2=10.363,P=0.169).Conclu-sion Age,neurotic personality traits,purpura location,the number of purpura recurrences,family care level,educational level of the primary caregiver,and whether the primary caregiver has anxiety or depression are influencing factors for anxiety occurrence in school-age children with recurrent HSP.Medical personnel should pay attention to children with high-risk factors for anxiety and formu-late corresponding preventive measures based on the above factors to reduce the anxiety incidence rate in school-age children with recurrent HSP.

Objective To explore the safety of minimally invasive esophagectomy (MIE) with three-field lymphadenectomy (3-FL) for esophageal squamous cell carcinoma (ESCC) by comparing the short-term outcomes between the 3-FL and the two-field lymphadenectomy (2-FL) in MIE. Methods The clinical data of patients with ESCC who underwent minimally invasive McKeown esophagectomy in our hospital from July 2015 to March 2022 were collected retrospectively. Patients were divided into a 3-FL group and a 2-FL group according to lymph node dissection method. And the clinical outcomes and postoperative complications were compared between the two groups. Results A total of 257 patients with ESCC were included in this study. There were 211 males and 46 females with an average age of 62.2±8.1 years. There were 109 patients in the 3-FL group and 148 patients in the 2-FL group. The operation time of the 3-FL group was about 20 minutes longer than that of the 2-FL group (P<0.001). There was no statistical difference between the two groups in the intraoperatve blood loss (P=0.376). More lymph nodes (P<0.001) and also more positive lymph nodes (P=0.003) were obtained in the 3-FL group than in the 2-FL group, and there was a statistical difference in the pathological N stage between the two groups (P<0.001). But there was no statistical difference in the incidence of anastomotic leak (P=0.667), chyle leak (P=0.421), recurrent laryngeal nerve injury (P=0.081), pulmonary complications (P=0.601), pneumonia (P=0.061), cardiac complications (P=0.383), overall complications (P=0.147) or Clavien-Dindo grading (P=0.152) between the two groups. Conclusion MIE 3-FL can improve the efficiency of lymph node dissection and the accuracy of tumor lymph node staging, but it does not increase the postoperative complications, which is worthy of clinical application.

Objective:To carry out evidence-based nursing for standardized management of stress hyperglycemia in perioperative period of gastrointestinal tumor patients, and to formulate indicators, analyze obstacles and promoting factors, formulate action strategies.Methods:Guided by the Johns Hopkins evidence-based nursing model, evidence were searched, evaluated and summarized. Clinical indicators and review methods were formulated to carry out quality review. From November 2021 to April 2022, the medical staff and patients in the gastrointestinal surgery department of the First Affiliated Hospital of Anhui Medical University who met the inclusion criteria were conducted, and the incidence of compliance rate was calculated. Based on the results of the baseline review, the obstacles and contributing factors were analyzed.Results:A total of 26 pieces of best evidence were included and 14 indicators were formulated for 48 medical staff and 45 patients to clinical review, among which the compliance rate of 7 indicators was less than 60%. The main obstacle factors were lack of procedures and instruments for management of perioperative stress hyperglycemia in gastrointestinal tumor patients, lack of knowledge of medical staff, etc. The main promoting factors were organizational support, good atmosphere of medical team cooperation, strong willingness to change, etc.Conclusions:There is a big gap between the clinical practice and the best evidence of perioperative stress hyperglycemia management in patients with gastrointestinal tumor. Action strategies should be put forward for obstacles and promoting factors to promote evidence transformation.

OBJECTIVE: To investigate the feasibility of a dual-crosslinked injectable hydrogel derived from acellular musclar matrix (AMM) for promoting myoblasts proliferation and myogenic differentiation. METHODS: Firstly, hyaluronic acid was oxidized with NaIO ₄ and methylated to prepare methacrylamidated oxidized hyaluronic acid (MOHA). Then, AMM obtained by washing enzymatically treated muscle tissue was aminolyzed to prepare aminated AMM (AAMM). MOHA hydrogel and AAMM were crosslinked using Schiff based reaction and UV radiation to prepare a dual-crosslinked MOHA/AAMM injectable hydrogel. Fourier transform infrared spectroscopy (FTIR) was used to characterize MOHA, AAMM, and MOHA/AAMM hydrogels. The injectability of MOHA/AAMM hydrogel were evaluated by manual injection, and the gelation performance was assessed by UV crosslinking. The rheological properties and Young's modulus of the hydrogel were examined through mechanical tests. The degradation rate of the hydrogel was assessed by immersing it in PBS. The active components of the hydrogel were verified using immunofluorescence staining and ELISA assay kits. The promotion of cell proliferation by the hydrogel was tested using live/dead staining and cell counting kit 8 (CCK-8) assays after co-culturing with C2C12 myoblasts for 9 days. The effect of the hydrogel on myogenic differentiation was evaluated by immunofluorescence staining and real time quantitative polymerase chain reaction (RT-qPCR). RESULTS: FTIR spectra confirmed the successful preparation of MOHA/AAMM hydrogel. The hydrogel exhibited good injectability and gelation ability. Compared to MOHA hydrogel, MOHA/AAMM hydrogel exhibited higher viscosity and Young's modulus, a reduced degradation rate, and contained a higher amount of collagen (including collagen type Ⅰ and collagen type Ⅲ) as well as bioactive factors (including epidermal growth factor, fibroblast growth factor 2, vascular endothelial growth factor, and insulin-like growth factor 1). The live/dead cell staining and CCK-8 assay indicated that with prolonged incubation time, there was a significant increase in viable cells and a decrease in dead cells in the C2C12 myoblasts within the MOHA/AAMM hydrogel. Compared with MOHA hydrogel, the difference was significant at each time point ( P<0.05). Immunofluorescence staining and RT-qPCR analysis demonstrated that the deposition of IGF-1 and expression levels of myogenic-related genes (including Myogenin, Troponin T, and myosin heavy chain) in the MOHA/AAMM group were significantly higher than those in the MOHA group ( P<0.05). CONCLUSION The MOHA/AAMM hydrogel prepared based on AMM can promote myoblasts proliferation and myogenic differentiation, providing a novel dual-crosslinked injectable hydrogel for muscle tissue engineering.

Objective:To analyze the epidemiological characteristics and related indicators of plague in Yulin City, Shaanxi Province, and to evaluate the risk of plague epidemic in the future and formulate scientific and reasonable prevention and control measures.Methods:The plague surveillance data of national (Dingbian County) and provincial (Yuyang District, Jingbian County, Hengshan District, Shenmu City, Fugu County) plague monitoring sites in Yulin City from 2011 to 2021 were collected through the China Disease Prevention and Control Information System Pestis Prevention and Control Management Information System, and the plague epidemic situation among humans and animals, the main host animals and their flea infection were analyzed by descriptive epidemiological methods. The expert consultation method and plague risk assessment tool V1.0 were used to assess the epidemic risk of the plague in Yulin City.Results:There was no human and animal plague epidemic in Yulin City from 2011 to 2021. In national monitoring site, the density of main host animal was 5.79/hm 2, ranging from 3.02/hm 2 to 9.08/hm 2,the dominant species was Mongolian gerbil, accounting for 98.21% (3 402/3 464); the capture rate of wild nocturnal rodents was 1.27% (350/27 600), ranging from 0.21% to 3.83%, the dominant species was Cricetulus barabensis, accounting for 44.86% (157/350); the flea infection rate of the rodent body was 16.91% (768/4 541), with a flea index of 0.40, the dominant flea species was the Nosopsyllus laeviceps kuzenkov, accounting for 66.54% (1 203/1 808). In provincial monitoring site, the density of main host animals was 0.49/hm 2, ranging from 0.31/hm 2 to 0.67/hm 2, the dominant species was Alashan ground squirrel, accounting for 63.61% (194/305); the capture rate of nocturnal rodents in the wild was 1.76% (560/31 795), ranging from 0.89% to 3.93%, the dominant species was Roborovski dwarf hamster, accounting for 26.61% (149/560); the capture rate of domestic rats was 2.37% (397/16 750), ranging from 1.48% to 3.10%, the rodents included Rattus norvegicus (47.36%, 188/397) and house mouse (52.64%, 209/397); the flea infection rate of the rat body was 13.26% (182/1 373), with a flea index of 0.40; the dominant flea species was Ophthalmopsylla jettmari, accounting for 45.23% (251/555). The 5 281 pathogenic culture samples and 2 110 serological test samples were all negative. The Pearson correlation analysis results showed that there was no correlation between rodent density and flea infection rate or flea index at national and provincial monitoring sites ( r = - 0.26, - 0.48, 0.09, 0.12, P > 0.05), while flea infection rate and flea index were positively correlated ( r = 0.67, 0.81, P < 0.05). In 2022, Yulin City, Shaanxi Province was not ruled out the possibility of human plague epidemic, and the risk of plague epidemic among animals was high. Conclusions:From 2011 to 2021, the density of the main host animals at the national and provincial monitoring sites in Yulin City has remained at a low level, and the flea index has increased. There is a risk of plague epidemic in Yulin City, so the monitoring work should be further strengthened, and emergency supplies and capacity reserves should be well prepared.

Transcranial direct current stimulation (tDCS) is a well-tolerated, safe and noninvasive physical brain stimulation method, which has been widely used in the treatment of some common mental disorders and neurological diseases and has achieved certain clinical effects. It is necessary to develop expert consensus on clinical treatment to improve the use norms in related fields. According to the clinical research published before August 2021 and the method of evidence-based medicine, we published an expert consensus on tDCS in the treatment of depressive disorders, schizophrenia, substance use-related disorders, obsessive-compulsive disorder, attention deficit hyperactivity disorder, autism, anxiety disorders, post-traumatic stress disorder, sleep disorders, pain, Parkinson′s disease, stroke, and epilepsy. The consensus also introduced the safety and efficacy of the clinical use of tDCS, and standardized the treatment process and operation technology, aiming to provide guidance for the clinical application of tDCS and promote the standardized development of this treatment technology in the future.

Objective:To investigate patients' compliance of endoscopic surveillance after endoscopic submucosal dissection (ESD) and the influencing factors.Methods:This study was a cross-sectional survey. The data of patients who underwent ESD in Xijing Digestive Hospital of Air Force Military Medical University from January 2014 to December 2015 were collected through questionnaire and telephone call. The questionnaire survey was conducted from May 1, 2019 to July 31, 2020. Patients' compliance for endoscopic surveillance and influencing factors were evaluated. Logistic regression model was used for multivariate analysis to determine independent risk factors affecting compliance of endoscopic surveillance.Results:A total of 413 questionnaires were collected, of which 331 (80.1%) patients were well complied with endoscopic surveillance, and 82 (19.9%) were not. Univariate analysis showed that gender ( χ2=4.68, P=0.034), lesion type ( χ2=10.10, P=0.002), educational background ( χ2=4.00, P=0.049), disposable income ( χ2=7.00, P=0.009), employment ( χ2=11.29, P=0.004) and medical insurance ( χ2=13.59, P=0.001) affected patients' endoscopic surveillance compliance. Logistic regression analysis indicated that patients with submucosal lesions were less likely to be compliant than patients with mucosal lesions with the same type of medical insurance ( P<0.001, OR=0.383, 95% CI: 0.227-0.644); and with the same lesion type, patients with urban medical insurance were more likely to be compliant than those with rural cooperative medical insurance ( P<0.001, OR=2.938, 95% CI: 1.696-5.090). Conclusion:The endoscopic surveillance compliance for post-ESD patients is related to the lesion type, the type of medical insurance, and the awareness of the disease. More attention should be paid to those with submucosal lesions and rural cooperative medical insurance due to their poor compliance. And it is necessary to improve health education on the disease for better surveillance compliance.
