Objective Tetanus is a serious infectious diseases with high mortality,which is an important global public health issue.This study aims to analyze the epidemiological burden and changing trends of tetanus in China from 1990 to 2021,providing a basis for disease prevention and control.Methods Epidemiological indicators and global socio-demographic index(SDI)related to tetanus in China were retrieved and collected from the 2021 Global Burden of Disease database(GBD 2021).The trend analysis of the incidence rate,mortality rate and disability-ad-justed life years(DALYs)rate of tetanus in China from 1990 to 2021 was conducted by Joinpoint 5.3 software.Results From 1990 to 2021,the age-standardized incidence rate(ASIR),age-standardized mortality rate(ASMR),and age-standardized disability-adjusted life years(DALYs)rate of tetanus in China decreased significantly(average annual percent change[AAPC]＜0,P＜0.001),with males being significantly higher than females.The crude incidence rate,crude mortality rate,and crude DALYs rate for all age groups showed overall declining trends,with the lar-gest decline in the 0-14 years age group.In 2021,the crude incidence rate,crude mortality rate,and crude DALYs rate of tetanus in the population aged 70-years were higher than those in the population aged 0-14,15-49,and 50-69 years groups.The ASIR,ASMR,and age-standardized DALYs rate of tetanus in China in 2021 were lower than the global level,only higher than those in the high SDI regions.Conclusion From 1990 to 2021,the disease burden of tetanus in China varied with gender and age,with an overall declining trend over time.It is necessary to strengthen tetanus health education for males and the ≥70 years population,and to improve the overall level of pri-mary prevention measures for tetanus.

Objective:To compare the anticoagulant efficacy and safety between argatroban and heparin in patients with liver failure complicated with hepatic encephalopathy undergoing artificial liver treatment.Methods:A total of 207 patients with liver failure complicated with hepatic encephalopathy who received artificial liver treatment in the intensive care unit (ICU) of Wuxi No.5 People′s Hospital from January 2021 to October 2024 were enrolled, including 105 cases in the argatroban group and 102 cases in the heparin group. Changes in coagulation function, hemoglobin (Hb), platelet (PLT) count, and model for end-stage liver disease (MELD) score before and after artificial liver treatment were compared between the two groups. The formation of deep vein thrombosis in the lower extremities, coagulation in the extracorporeal circulation circuit and plasma separator, bleeding at the deep venous catheter site were compared between the two groups. The 28-day survival outcome of the patient were recorded. Two independent sample t-test, rank sum test, and chi-square test were used for statistical comparisons, and the Kaplan-Meier method and log-rank test were used to analyze the survival rate of patients. Results:There were no statistically significant differences in activated partial thromboplastin (APTT), international normalized ratio (INR), Hb and PLT count before and after artificial liver treatment in the argatroban group ( Z=-1.74, -1.80, -1.26 and -0.52, respectively, all P>0.05), while the MELD score after treatment was lower than that before treatment and the difference was statistically significant ( t=6.49, P<0.001). After artificial liver treatment, the APTT in the argatroban group was 47.10(42.65, 51.90) s, which was shorter than that in the heparin group (56.05(50.02, 63.00) s). The INR, Hb, and PLT count in the argatroban group were 2.00(1.65, 2.54), 98.00(88.00, 112.00) g/L, and 92.00(75.50, 106.00)×10 9/L, respectively, which were all higher than those in the heparin group, which were 1.56(1.22, 1.93) g/L, 90.50(80.00, 104.75) g/L, and 74.00(64.75, 99.50)×10 9/L, respectively. The differences were all statistically significant ( Z=-7.16, -5.28, -3.05 and -3.32, respectively, all P<0.05). There was no statistically significant difference in MELD scores between the two groups ( P=0.250). The incidence of coagulation in the extracorporeal circulation circuit and plasma separator and bleeding at the deep venous catheter site in the argatroban group was 5.71%(6/105) and 1.90%(2/105), respectively, which were both lower than those in the heparin group (14.71%(15/102) and 9.80%(10/102), respectively). The differences were both statistically significant ( χ2=4.59 and 5.91, respectively, both P<0.05). At the end of the 28-day follow-up, the mortality rates in the argatroban group and the heparin group were 22.9%(24/105) and 34.3%(35/102), respectively, and the difference was not statistically significant ( χ2=3.33, P=0.068). There was no statistically significant difference in the 28-day survival rate between the argatroban group and the heparin group ( χ2=2.09, P>0.05). Conclusions:Argatroban has a relatively minor impact on PLT count and Hb when it is used in artificial liver treatment for patients with liver failure complicated with hepatic encephalopathy. The incidence of coagulation in extracorporeal circulation circuits and plasma separators is low, and the risk of bleeding at the deep venous catheters is low. Argatroban is highly safe, which provides a new anticoagulation option for patients with a high risk of bleeding.

Objective:To explore the correlation and predictive value of the blood urea nitrogen to serum albumin ratio (BAR) in the development of sepsis among patients with acute-on-chronic liver failure (ACLF).Methods:A total of 410 patients diagnosed with ACLF who were admitted to Wuxi Fifth People′s Hospital between January 1st, 2020 and December 31st, 2024 were enrolled in this study. Demographic information, laboratory test indicators, and other clinical data were retrospectively analyzed. Participants were stratified into two groups using a 6∶4 allocation ratio, comprising a training set of 246 patients and a validation set of 164 patients, the clinical data of two groups were compared. Logistic regression was employed to evalute the influencing factors of sepsis during hospitalization in ACLF patients. Additionally, the predictive value of different factors for sepsis occurrence was evaluated using receiver-operating characteristic curve analysis. DeLong test was used to compare the area under the curve.Results:The comparison of baseline data between the training set and the validation set revealed no statistically significant differences (all P>0.05). A total of 197 sepsis cases were observed during the study period. Multivariate logistic regression analysis revealed that both BAR and the sequential organ failure assessment (SOFA) score were independent influencing factors for sepsis development in ACLF patients (odds ratio ( OR)=1.274, 95% confidence interval (95% CI) 1.075 to 1.510, P=0.005; OR=1.142, 95% CI 1.038 to 1.256, P=0.006). In the training set, the area under the curve (AUC) of BAR for predicting sepsis in ACLF patients was 0.802, which was superior to that of the SOFA score (AUC=0.706) ( Z=2.16, P=0.031). The validation set showed the predictive ability of BAR with an AUC of 0.726, which was superior to the SOFA score′s performance (AUC=0.606) ( Z=2.28, P=0.023). Conclusions:BAR could independently predict sepsis development in ACLF patients with significant prognostic value. BAR could be used as a clinically useful biomarker for sepsis risk stratification.

Objective:Exploratory study on the relationship between TCM syndrome types, TCM constitution and clinical symptoms of idiopathic central precocious puberty children and rapidly progressive early development children in Shanghai, so as to provide a basis for early intervention and syndrome differentiation and treatment.Methods:A cross-sectional study and retrospectively enrolled. Through questionnaire survey, the basic information, clinical symptoms and TCM constitution of children diagnosed with idiopathic central precocious puberty and rapidly progressive early development were collected from the Pediatric Endocrinology Clinic of Affiliated Shuguang Hospital of Shanghai University of Traditional Chinese Medicine from July to August 2022, and the correlation between the distribution, differentiation and clinical symptoms of TCM constitution in children with idiopathic central precocious puberty and children with rapidly progressive precocious puberty in Shanghai were explored through data analysis.Results:① Fast progressive early development children with higher BMI and age than idiopathic central precocious puberty were statistically significant ( P<0.05), and no significant difference in the sex composition ratio between the two groups. ② Among children with idiopathic central precocious puberty and children with rapid progressive early development, the proportion of liver depression fire syndrome was the highest, 59.15% (42/71) and 46.51% (60/129) respectively, and the proportion of Qi depression was the highest, 35.21% (25/71) and 36.43% (47/129) respectively. However, there was no significant difference in the TCM syndrome types and physical distribution of the two groups. ③ The TCM syndrome types of 200 precocious children weres correlated with physical distribution, among which Yin deficiency fire flourishing syndrome was significantly associated with Yin deficiency, liver stagnation fire syndrome was significantly correlated with qi depression, and phlegm dampness obstruction syndrome was significantly correlated with phlegm dampness and Yang deficiency ( P<0.01). ④ A total of 200 children with precocious puberty were more female than male, male BMI was higher than female, and the BMI of children with precocious puberty was higher than other syndrome types, and the differences were statistically significant ( P<0.01). Liver stasis fire syndrome was the highest proportion between boys and girls, but there was no obvious difference in TCM syndrome types between different genders. The highest proportion of breast pain in clinical symptoms was 22.19% (69/311). Conclusion:Children with idiopathic central precocious puberty and rapidly progressive early development children have differences in age and BMI, with no obvious difference in gender composition, TCM syndrome type and physical distribution, but there is a correlation between TCM syndrome type and physical constitution of precocious puberty children.

[Objective] To investigate the correlation between human leukocyte antigen (HLA) gene polymorphism and hepatitis B virus (HBV) infection. [Methods] Venous blood samples were collected from 501 healthy individuals undergoing physical examinations at Yan’an Hospital in Kunming, Yunnan Province. Enzyme linked immunosorbent assay (ELISA) was used to detect HBV halves. Based on the results of HBV half detection, the patients were divided into three groups: HBV carrier group, previous infection group, and healthy control group. The HLA-A antigen genotype was detected using polymerase chain reaction with sequence specific primers (PCR-SSP) genotyping technology, and the distribution frequency of HLA-A gene polymorphism was compared between HBV carrier group and healthy control group, as well as between previous infection group and healthy control group. SPSS17.0 software was used for data statistical analysis. [Results] In the healthy control group, the HLA-A2 positivity rate was 47.49%, and the allele frequency was 31.29%.The overall frequency of gene distribution in the healthy control group was consistent with the HLA-A allele table commonly and confirmed in China published by the Chinese Bone Marrow Bank. The HLA-A2 positivity rate and allele frequency in the HBV carrier group were 63.04% and 42.23%, respectively; The difference in HLA-A2 positivity rate and allele frequency among carriers was statistically significant (P<0.05). the HLA-A2 positivity rate and allele frequency in the HBV previous infection group were 56.14% and 35.97%, respectively, which did not significantly differ from those in the healthy control group (P>0.05). [Conclusion] HLA-A2 gene may be a susceptibility gene for chronic hepatitis B HBV carriers.

Objective:To investigate the effects of gelatin methacrylate anhydride (GelMA) hydrogel loaded with small extracellular vesicles derived from human umbilical cord mesenchymal stem cells (hUCMSCs-sEVs) in the treatment of full-thickness skin defect wounds in mice.Methods:This study was an experimental study. hUCMSCs-sEVs were extracted by ultracentrifugation, their morphology was observed through transmission electron microscope, and the expression of CD9, CD63, tumor susceptibility gene 101 (TSG101), and calnexin was detected by Western blotting. The human umbilical vein endothelial cells (HUVECs), the 3 rd and 4 th passages of human epidermal keratinocytes (HEKs) and human dermal fibroblasts (HDFs) were all divided into blank control group (routinely cultured) and hUCMSC-sEV group (cultured with the cell supernatant containing hUCMSCs-sEVs). The cell scratch test was performed and the cell migration rates at 6, 12, and 24 h after scratching were calculated, the cell Transwell assay was performed and the number of migration cells at 12 h after culture was calculated, and the proportion of proliferating cells was detected by 5-acetylidene-2'-deoxyuridine and Hoechst staining at 24 h after culture, with sample numbers being all 3. The simple GelMA hydrogel and the GelMA hydrogel loaded with hUCMSCs-sEVs (hereinafter referred to as hUCMSC-sEV/GelMA hydrogel) were prepared. Then the micromorphology of 2 kinds of hydrogels was observed under scanning electron microscope, the distribution of hUCMSCs-sEVs was observed by laser scanning confocal microscope, and the cumulative release rates of hUCMSCs-sEVs at 0 (immediately), 2, 4, 6, 8, 10, and 12 d after soaking hUCMSC-sEV/GelMA hydrogel in phosphate buffer solution (PBS) were measured and calculated by protein colorimetric quantification ( n=3). Twenty-four 6-week-old male C57BL/6J mice were divided into PBS group, hUCMSC-sEV alone group, GelMA hydrogel alone group, and hUCMSC-sEV/GelMA hydrogel group according to the random number table, with 6 mice in each group, and after the full-thickness skin defect wounds on the back of mice in each group were produced, the wounds were performed with PBS injection, hUCMSC-sEV suspenson injection, simple GelMA coverage, and hUCMSC-sEV/GelMA hydrogel coverage, respectively. Wound healing was observed on post injury day (PID) 0 (immediately), 4, 8, and 12, and the wound healing rates on PID 4, 8, and 12 were calculated, and the wound tissue was collected on PID 12 for hematoxylin-eosin staining to observe the structure of new tissue, with sample numbers being both 6. Results:The extracted hUCMSCs-sEVs showed a cup-shaped structure and expressed CD9, CD63, and TSG101, but barely expressed calnexin. At 6, 12, and 24 h after scratching, the migration rates of HEKs (with t values of 25.94, 20.98, and 20.04, respectively), HDFs (with t values of 3.18, 5.68, and 4.28, respectively), and HUVECs (with t values of 4.32, 19.33, and 4.00, respectively) in hUCMSC-sEV group were significantly higher than those in blank control group ( P<0.05). At 12 h after culture, the numbers of migrated HEKs, HDFs, and HUVECs in hUCMSC-sEV group were 550 ±23, 235 ±9, and 856 ±35, respectively, which were significantly higher than 188 ±14, 97 ±6, and 370 ±32 in blank control group (with t values of 22.95, 23.13, and 17.84, respectively , P<0.05). At 24 h after culture, the proportions of proliferating cells of HEKs, HDFs, and HUVECs in hUCMSC-sEV group were significantly higher than those in blank control group (with t values of 22.00, 13.82, and 32.32, respectively, P<0.05). The inside of simple GelMA hydrogel showed a loose and porous sponge-like structure, and hUCMSCs-sEVs was not observed in it. The hUCMSC-sEV/GelMA hydrogel had the same sponge-like structure, and hUCMSCs-sEVs were uniformly distributed in clumps. The cumulative release rate curve of hUCMSCs-sEVs from hUCMSC-sEV/GelMA hydrogel tended to plateau at 2 d after soaking, and the cumulative release rate of hUCMSCs-sEVs was (59.2±1.8)% at 12 d after soaking. From PID 0 to 12, the wound areas of mice in the 4 groups gradually decreased. On PID 4, 8, and 12, the wound healing rates of mice in hUCMSC-sEV/GelMA hydrogel group were significantly higher than those in the other 3 groups ( P<0.05); the wound healing rates of mice in GelMA hydrogel alone group and hUCMSC-sEV alone group were significantly higher than those in PBS group ( P<0.05). On PID 8 and 12, the wound healing rates of mice in hUCMSC-sEV alone group were significantly higher than those in GelMA hydrogel alone group ( P<0.05). On PID 12, the wounds of mice in hUCMSC-sEV/GelMA hydrogel group showed the best wound epithelization, loose and orderly arrangement of dermal collagen, and the least number of inflammatory cells, while the dense arrangement of dermal collagen and varying degrees of inflammatory cell infiltration were observed in the wounds of mice in the other 3 groups. Conclusions:hUCMSCs-sEVs can promote the migration and proliferation of HEKs, HDFs, and HUVECs which are related to skin wound healing, and slowly release in GelMA hydrogel. The hUCMSC-sEV/GelMA hydrogel as a wound dressing can significantly improve the healing speed of full-thickness skin defect wounds in mice.
