Objective To investigate the factors influencing the development of extra-pulmonary tuberculosis(EPTB)in patients with viral hepatitis complicated by pulmonary tuberculosis(PTB).Methods A retrospective analysis was conducted on 427 patients with Hepatitis B Virus(HBV)and Hepatitis C Virus(HCV)infections complicated by PTB admitted to the tuberculosis department of Kunming Third People's Hospital from January 2015 to December 2020.Patients were divided into the EPTB complication group(n=72)and the non-EPTB complication group(n=355)based on the presence of EPTB.Clinical treatment data of patients were collected.Univariate and multivariate Logistic regression analyse were used to screen independent risk factors for EPTB as predictive factors.A nomogram prediction model was established for Extrapulmonary Tuberculosis(EPTB)complications in patients with viral hepatitis and Pulmonary Tuberculosis(PTB),evaluated using the Hosmer-Lemeshow test and ROC curve analysis.Results Among the 427 patients,292(68.3%)were male and 135(31.7%)were female,with 72 cases of EPTB,resulting in an incidence rate of 16.86%.In the EPTB group,there were 34 males(47.2%)and 38 females(52.8%).The types of EPTB included tuberculous pleuritis(21 cases,29%),tuberculous peritonitis(16 cases,22%),lymph node tuberculosis(13 cases,18%),tuberculous encephalitis(5 cases,6%),intestinal tuberculosis(6 cases,8%),bone tuberculosis(5 cases,6%),pelvic tuberculosis(3 cases,4%),and genitourinary tuberculosis(3 cases,4%).Multivariate logistic regression analysis showed that gender(OR=0.425,95%CI:0.250-0.722,P=0.02),low triglyceride(TG)levels(OR=0.837,95%CI:0.717-0.978,P=0.025),the tuberculosis-specific antigen A(ESAT-6)(OR=1.007,95%CI:1.003～1.011 were independent influencing factors for EPTB in patients with PTB complicated by HBV and HCV infections.The optimal cutoff value for the nomogram model is 0.192,with a sensitivity of 0.611,specificity of 0.710,Youden index of 0.741,positive likelihood ratio of 2.103,and negative likelihood ratio of 0.548.The Hosmer-Lemeshow test yielded χ2=2.631,P=0.955.ROC curve analysis showed an AUC of 0.693,95%CI:0.629 1～0.7574.Conclusion The prediction model based on gender,low TG levels and ESAT-6 can well predict the occurrence of EPTB to some extent,providing a reference for clinical treatment.

Objective To evaluate the relationship between nutritional parameters and the risk of venous thromboembolicism(VTE)in patients with tuberculosis so as to identify the risk factors and predictors of thrombosis and assist in the early identification of high-risk factors for VTE in patients with the pulmonary tuberculosis.Methods A total of 323 patients diagnosed with the pulmonary tuberculosis and hospitalized in Kunming Third People's Hospital from August 2021 to August 2023 were collected.According to the VTE risk assessment of non-operative patients,they were divided into the high-risk group and the low-risk group respectively with 116 and 207 in each group.The nutritional indicators with statistically significant differences between the two groups were screened by Lasso regression.Multivariate Logistic regression was used to screen the independent risk factors for high VTE risk in pulmonary tuberculosis patients,and a nomogram prediction model was constructed.The prediction model was evaluated by receiver operating characteristic curve(ROC),calibration curve,decision curve,and influence curve.Results Patients in the high-risk group were significantly older than those in the low-risk group(59 vs.41,P<0.001),hypertension,gender,and Type 2 diabetes did not differ significantly(P values were 0.084,0.724 and 0.488,respectively).9 variables were selected from the inter-group comparison and Lasso regression,including ALB,HCT,NRS2002 scores,HBDH,RDW-SD,RDW-CV,TG,CONUT scores,and NEFA.Multivariate Logistic regression analysis showed that ALB,NRS2002 scores,RDW-SD,and CONUT scores were independent influencing factors for the high risk of VTE scores in patients with tuberculosis(P<0.005).Area under the ROC curve showed that the AUC(0.892)for high-risk VTE scores in patients with the pulmonary tuberculosis was greater than that of ALB(0.803),NRS2002 score(0.735),RDW-SD(0.685),and CONUT score(0.774).Fitting prediction model:Logit(P):Y=0.433×NRS-0.136×ALB+0.411×CONUT score+0.072×RDW-SD-1.770,P=1/(1+e-Y)(Y:prediction index,P:prediction probability).Calibration curve showed that the model prediction tended to be consistent with the actual results(U:>0.05),and the decision curve and influence curve showed that the model can bring clinical benefits.Conclusion ALB,NRS2002 scores,RDW-SD,and CONUT scores are independent influencing factors for the high risk of VTE scores in patients with tuberculosis.They can guide the clinical practice,improve these indicators as soon as possible,reduce VTE scores,and reduce the thrombosis risk.At the same time,the prediction model performs well in the verification cohort,with its discrimination ability,calibration accuracy and clinical utility(decision curve analysis)all reaching a satisfactory level.

Objective:Based on the Janus kinase 2(JAK2)/signal transducer and activator of transcription 3(STAT3)signaling pathway,to explore the influences of Liyan syrup on pharyngeal tissue injury and pharyngeal mucosal repair in rats with chronic phar-yngitis.Methods:SD rats were randomly separated into control group,model group,Liyan syrup group,RO8191(JAK2/STAT3 acti-vator)group,Liyan syrup+RO8191 group,the model group and drug intervention group were treated with ammonia water to stimulate the pharynx to build a chronic pharyngitis model,while rats in control group were injected with an equal dose of normal saline into the pharynx.After the intervention of Liyan Syrup and RO8191,the general condition of rats and the apparent state of pharynx were detected,and the apparent state of pharynx was scored;the pathological changes of pharynx of rats were measured by HE staining;the proportions of CD4+T and CD8+T and the ratio of CD4+T/CD8+T in peripheral blood T lymphocyte subsets of rats were measured by flow cytometry;the levels of serum tumor necrosis factor alpha(TNF-α),IL-6,IL-10,malondialdehyde(MDA),reactive oxygen species(ROS)and total antioxidant capacity(T-AOC)were measured by kits;the expressions of JAK2/STAT3 pathway-related proteins in rat pharyngeal tissues were measured by immunoblotting.Results:Compared with control group,the pharyngeal tissue of model group showed obvious pathological morphological damage,the peripheral blood CD4+T proportion and CD4+T/CD8+T,IL-10 and serum T-AOC level decreased(P<0.05),the pharyngeal appearance state score,CD8+T ratio,serum TNF-α,IL-6,MDA and ROS levels,and pharyngeal tissue p-JAK2/JAK2 and p-STAT3/STAT3 levels increased(P<0.05);compared with model group and Liyan syrup+ RO8191 group,the pathological and morphological damage of the pharynx of rats in Liyan syrup group was alleviated,the peripheral blood CD4+T and CD4+T/CD8+T,IL-10,and serum T-AOC level all increased(P<0.05),and the pharyngeal appearance state score,CD8+T,serum TNF-α,IL-6,MDA and ROS levels,and pharyngeal tissue p-JAK2/JAK2 and p-STAT3/STAT3 levels all decreased(P<0.05);the change trend of each index in RO8191 group was opposite to that in Liyan syrup group.Conclusion:Liyan syrup can reduce inflammation and oxidative stress by inhibiting the activation of JAK2/STAT3 signal,enhance anti-inflammatory and antioxidant capacity,relieve throat tissue damage and repair pharyngeal mucosa in rats with chronic pharyngitis.

Objective:To compare demographic characteristics,clinical characteristics,therapeutic characteris-tics and physiological indicators of patients with bipolar Ⅰ disorder and bipolar Ⅱ disorder.Methods:A total of 381 patients with bipolar disorder(BD)diagnosed by the Diagnostic and Statistical Manual of Mental Disorders 5 th Edi-tion(DSM-5)were selected,including 302 patients with BD-Ⅰ(79.27％),74 patients with BD-Ⅱ(19.42％)and 5 patients with other specific and related disorders(1.31％).Demographic and clinical characteristics were collected with self-designed clinical information questionnaire.Multivariate logistic regression and multivariate linear regres-sion analysis were used for analysis.Results:Compared with patients with BD-Ⅱ,patients with BD-Ⅰ had more risk to have psychotic features(OR=5.75,95％CI:2.82-11.76),longer disease duration,and more repeated transcra-nial magnetic therapy(OR=3.09,95％CI:1.02-9.35),higher uric acid,total cholesterol and high-density lipo-protein.BD-Ⅰ in Han nationality was more common(OR=11.50,95％CI:1.76-75.30),and had lower education level(OR=10.22,95％CI:1.16-89.77),and less family history of psychosis(OR=2.34,95％CI:1.01-5.42).Conclusion:There are significant differences between BD-Ⅰ and BD-Ⅱ in demographic and clinical charac-teristics,treatment status,and physiological indicators,which could provide clues for exploring the pathogenesis of bipolar disorder.

Objective:To compare clinical characteristics,treatment patterns and physiological indicators in bipolar disorder(BD)patients with different age of onset.Methods:Totally 380 patients with DSM-5 BD were se-lected in this study.Psychiatrists diagnosed the patients using the Mini International Neuropsychiatric Interview.The clinical information questionnaire and the Global Assessment of Functioning scale were utilized to collected clinical characteristics,treatment status,and physiological indicators.The onset age of BD was divided into 21 and 35 years as cut-off points.Multivariate logistic regression and linear regression were used to analyze related factors.Results:Among the 380 patients with BD,199 cases were early-onset group(52.4％),121 cases were middle-onset group(31.8％),and 60 cases were late-onset group(15.8％).There were 26.6％of patients in the early-onset group in-itially diagnosed as depression,23.1％in the middle-onset group,and 11.7％in the late-onset group.Multivariate analysis revealed that compared to the early-onset group of BD,the middle-onset(OR=2.22)and late-onset(OR=4.99)groups had more risk to experience depressive episodes,and the late-onset group(OR=6.74)had 6.74 times of risk to suffer from bipolar Ⅱ disorder.Additionally,patients in the middle-onset(β=-1.52)and late-on-set(β=-4.29)groups had shorter durations of delayed treatment,and those in the middle-onset(β=-1.62)and late-onset(β=-3.14)groups had fewer hospitalizations.Uric acid levels were lower in both the middle-onset(β=-28.39)and late-onset(β=-31.47)groups,and total cholesterol level was lower in the middle-onset group(β=-0.23).Conclusion:Patients with BD in different age of onset show significant differences in clinical charac-teristics,treatment conditions and physiological indicators.

Infectious bone defect is bone defect with infection or as a result of treatment of bone infection. It requires surgical intervention, and the treatment processes are complex and long, which include bone infection control,bone defect repair and even complex soft tissue reconstructions in some cases. Failure to achieve the goals in any step may lead to the failure of the overall treatment. Therefore, infectious bone defect has been a worldwide challenge in the field of orthopedics. Conventionally, sequestrectomy, bone grafting, bone transport, and systemic/local antibiotic treatment are standard therapies. Radical debridement remains one of the cornerstones for the management of bone infection. However, the scale of debridement and the timing and method of bone defect reconstruction remain controversial. With the clinical application of induced membrane technique, effective infection control and rapid bone reconstruction have been achieved in the management of infectious bone defect. The induced membrane technique has attracted more interests and attention, but the lack of understanding the basic principles of infection control and technical details may hamper the clinical outcomes of induced membrane technique and complications can possibly occur. Therefore, the Chinese Orthopedic Association organized domestic orthopedic experts to formulate An evidence-based clinical guideline for the treatment of infectious bone defect with induced membrane technique ( version 2023) according to the evidence-based method and put forward recommendations on infectious bone defect from the aspects of precise diagnosis, preoperative evaluation, operation procedure, postoperative management and rehabilitation, so as to provide useful references for the treatment of infectious bone defect with induced membrane technique.

OBJECTIVE To establish the fingerprint of Huangqin decoction （HQD）， to separate the phase states and screen the active phase states of antidermatophytic activity so as to study the spectrum-effect relationship. METHODS HPLC method was adopted using baicalin as reference， the fingerprints of 10 batches of HQD were drawn and the similarity evaluation was carried out using the Similarity Evaluation System of Chromatographic Fingerprint of TCM （2012 edition） to determine the common peak； the phase states of HQD were separated and characterized by high-speed centrifugation and membrane dialysis. The minimum inhibitory concentrations （MIC） of HQD and its different phase states against Trichophyton mentagrophytes were determined simultaneously. Using the peak area of 37 common peaks as independent variable， MIC as dependent variable， Pearson correlation analysis was performed by using SPSS 21.0 software. RESULTS A total of 37 common peaks were obtained in HPLC fingerprints of 10 batches of HQD， with the similarity higher than 0.99. Ten components were identified， such as albiflorin， paeoniflorin， liquiritin apioside， baicalin， melaleuca glycoside A， wogonoside， baicalein， glycyrrhizic acid， wogonin and oroxylin A. HQD was split into 3 phase states， such as precipitation phase （HQD-P）， solution phase （HQD-S） and nano phase （HQD-N）. The morphology of HQD-P was irregular granular， and the average particle size was 4.670-91.522 μm. The morphology of HQD-S was uniform flakes， and no particle size was detected. HQD-N was spherical in shape and the particle size was （129.0±12.9） nm. MIC values of each phase state of HQD against T. mentagrophytes in different phase states were HQD-N （4.64 mg/mL） ＜HQD （5.85 mg/mL） ＜HQD-P （7.37 mg/mL） ＜HQD-S （12.89 mg/mL） at the same dosage. Pearson correlation analysis showed that the peak area of 25 of the 37 common peaks （including identified components） was significantly negatively correlated with MIC （absolute values of correlation coefficient＞0.95 and P＜0.05）. CONCLUSIONS The chemical composition of 10 batches of HQD is consistent； HQD-N is the active phase state of HQD. Ten components such as paeoniflorin， liquiritin apioside and baicalin may be the main active components of HQD. The antidermatophytic effect of HQD is closely related to its component content and physical phase state.

Objective: To investigate the epidemiological characteristics of sexually transmitted diseases (STDs) in Zhejiang Province from 2018 to 2022, so as to provide insights into improving STDs prevention and control strategies. Methods: Data of syphilis, gonorrhea, condyloma acuminatum, genital herpes and genital Chlamydia trachomatis infections reported in Zhejiang Province from 2018 to 2022 were collected from the Infectious Disease Surveillance System of Chinese Disease Prevention and Control Information System. The temporal, spatial and population distribution of STDs were analyzed, and the trends in incidence of STDs were evaluated using annual percent change (APC). Results: A total of 386 770 STDs cases were reported in Zhejiang Province from 2018 to 2022, with mean annual reported incidence of 127.80/105. The mean annual reported incidence from high to low was syphilis (44.11/105), genital Chlamydia trachomatis infections (40.20/105), gonorrhea (24.92/105), condyloma acuminatum (13.32/105), and genital herpes (5.34/105). The incidence of STDs appeared a tendency towards a decline from 2018 to 2022 (APC=-9.332%, P<0.05), with an average annual growth rate of -9.41%. Syphilis (APC=-11.536%, P<0.05), condyloma acuminatum (APC=-7.509%, P<0.05), and genital Chlamydia trachomatis infections (APC=-9.009%, P<0.05) showed a appeared a tendency towards a decline. The top three highest reported incidence were reported in Hangzhou City (185.98/105), Taizhou City (133.85/105) and Lishui City (122.73/105), respectively. The mean annual reported incidence of females was higher than that of males (140.60/105 vs. 117.83/105; P<0.05). Most STDs cases were at ages of 20 to 49 years (265 314 cases, 68.60%). Farmers (118 096 cases, 30.53%), household and unemployed personnel (85 924 cases, 22.22%) were the predominant occupation. Conclusions The incidence of STDs appeared a tendency towards a decline in Zhejiang Province from 2018 to 2022, with regional differences in incidence. People at ages of 20 to 49 years, farmers, household and unemployed personnel are high-risk populations for STDs.

Objective:To analyze spatiotemporal distribution characteristics of syphilis in Zhejiang province from 2016 to 2020, to explore cluster areas of syphilis cases, and to provide a theoretical basis for accurate prevention and control of syphilis.Methods:Data on reported syphilis cases in Zhejiang province from 2016 to 2020 were collected from the notifiable infectious disease surveillance system in China Disease Control and Prevention Information System. The ArcGIS10.2 software was used as a data management and presentation platform to establish a database for spatial analysis of syphilis in Zhejiang province from 2016 to 2020, and spatial autocorrelation analysis of reported syphilis incidence was conducted. The SaTScan 9.6 software was used for spatiotemporal scanning analysis.Results:A total of 158 420 cases of syphilis were reported in Zhejiang province from 2016 to 2020, and the average annual reported incidence rate was 49.07 per 100 000 in all counties and districts (range: 20.52 per 100 000-124.29 per 100 000) . The overall spatial distribution pattern of syphilis cases in Zhejiang province was characterized by higher reported syphilis incidence in the West area and lower incidence in the middle area. Global autocorrelation analysis showed that all the global Moran′s I indices from 2016 to 2020 were over 0, Z values were over 1.96, and P values were below 0.001, suggesting the spatial clustering of reported syphilis cases. Local autocorrelation analysis showed that there were 2 high-high clustering areas (Tonglu and Chun′an counties in Hangzhou city, Jingning county in Lishui city) , and 1 low-low clustering area (Jindong district, Dongyang and Yongkang county-level cities in Jinhua city) . Local hot-spot analysis with G statistic showed that there were 6 positive hot-spot areas and 8 negative hot-spot areas of syphilis cases in Zhejiang province. SaTScan spatiotemporal scanning analysis revealed 3 clustering areas, mainly distributed in Taizhou and Zhoushan cities along the eastern coast, and some counties and districts in the southwestern mountainous areas. Conclusions:The reported incidence rate of syphilis in Zhejiang province is characterized by spatial clustering. In the future, prevention and control of syphilis should be strengthened in southwestern mountainous areas, eastern islands, and other remote areas as well as areas with poor transportation.
