Objective To analyze the trend of global cellulitis disease burden from 1990 to 2019, and to provide a theoretical basis for the prevention and control of cellulitis disease. Methods The Global Burden of Disease 2021 (GBD2021) data were collected, and data on the incidence, mortality, and disability-adjusted life year (DALY) of cellulitis were analyzed for each country worldwide. The estimated annual percentage change (EAPC) and age-standardized rate (ASR) were used to estimate the trend change of cellulitis from 1990 to 2021. Results The global burden of cellulitis increased significantly in 2021, with 55.96 million cases, 28.9 million deaths and 876.1 million DALYs, respectively. Incidence and mortality rates were generally higher in males than in females. The incidence and DALYs were higher in high SDI regions, with the highest burden observed in South Asia. In contrast, East Asia exhibited the lowest burden and demonstrated a declining trend. There were significant differences between countries, with India having the highest prevalence, the United States having the highest incidence, and Bahrain having the fastest growing rate.In 2021, China had the lowest age-standardised incidence of cellulitis in the world and the fastest declining age-standardised incidence and age-standardised DALYs. Conclusion The global disease burden of cellulitis is increasing from 1990-2021, and cellulitis remains an an important global public health problem. Targeted preventive meausres should be taken in areas with different economical levels. Men, middle-aged and elderly people, and newborns are the key groups in need of attention and health education.

OBJECTIVES: To investigate the effect of in vitro cultured calculus bovis (ICCB) on cerebral ischemia/reperfusion injury (CIRI) and its mechanism. METHODS: A CIRI rat model and a cell model were induced by middle cerebral artery occlusion (MCAO) in Sprague Dawley rats and oxygen glucose deprivation/reperfusion (OGD/R) in BV2 cells, respectively. The CIRI rat model was evaluated using the modified neurological severity score (mNSS), brain water content, and cerebral infarction volume after 1.5 h of ischemia followed by 72 h of reperfusion. Histopathological changes in the cortex and hippocampal CA1 region were observed with hematoxylin and eosin staining. Microglial polarization and NOD-like receptor thermal protein domain associated protein (NLRP) 3 inflammasome expression in the cortex were examined by immunofluorescence. BV2 cell viability was measured via MTT assay after treatment with ICCB and Nigericin. The expressions of NLRP3, ASC, caspase-1 proteins and inflammatory cytokines were detected with Western blotting in OGD/R treated BV2 cells (0.5 h OGD+24 h reperfusion) and in cells pretreated with Nigericin for 24 h. RESULTS: ICCB treatment significantly improved neurological function, reduced cerebral infarct volume and brain water content, and mitigated pathological damage in the cortical and hippocampal CA1 regions of rats subjected to CIRI (all P<0.05). ICCB promoted the transition of cortical microglia from M1 to M2 phenotypes and suppressed NLRP3 activation in microglial cells (all P<0.01). ICCB significantly down-regulated the expression of NLRP3, ASC, and caspase-1 proteins, and reduced the secretion of IL-18 and IL-1β in BV2 cells of OGD/R model (all P<0.01). In addition, Nigericin significantly reversed the salvage effect of ICCB on model cells (both P<0.01) and the modulation of inflammatory cytokines (P<0.05). CONCLUSIONS ICCB exerts a protective effect against CIRI by mitigating neuroinflammation, through the reduction of M1 microglial polarization, promotion of M2 conversion, and suppression of the NLRP3/ASC/caspase-1 signaling pathway.

Objective To investigate the expression of microRNA(miR)-143-3p and signal transduction and transcriptional activator protein(STAT)3 in serum of patients with hepatocellular carcinoma(HCC)and its clinical significance.Methods A total of 110 HCC patients admitted to Rugao People's Hospital from Jan-uary 2022 to February 2023 were selected as HCC group,and 40 healthy people who underwent physical ex-amination during the same period were selected as healthy control group.The expression of miR-143-3p and STAT3 mRNA was compared in the serum of two groups.In addition,they were divided into good prognosis group(n=82)and poor prognosis group(n=28),according to the prognosis of HCC patients followed up for 1 year.Multivariate Logistic regression analysis was used to analyze the the influencing factors of poor prog-nosis in HCC patients.The predictive efficacy of serum miR-143-3p and STAT3 mRNA expression on poor prognosis of HCC patients was analyzed by receiver operating characteristic(ROC)curve.Results Compared with healthy control group,the expression level of miR-143-3p in serum of HCC group was lower(P＜0.05),while the expression level of STAT3 mRNA was higher(P＜0.05).Multivariate Logistic regression analysis showed that microvascular invasion,maximum diameter of tumor＞5 cm,down-regulated serum miR-143-3p expression and up-regulated STAT3 mRNA expression were independent risk factors for poor prognosis of HCC patients(P＜0.05).ROC curve showed that the area under the curve of serum miR-143-3p,STAT3 mR-NA and their combined detection for predicting the poor prognosis of HCC patients were 0.888,0.810 and 0.922,respectively,and the combined detection had the best predictive value(P＜0.05).Conclusion The ex-pression of miR-143-3p is abnormally down-regulated in the serum of HCC patients,while the mRNA of STAT3 is abnormally up-regulated.The combined detection of miR-143-3p and STAT3 has good predictive value for the poor prognosis of HCC patients.

Objective To conduct a reliability and validity analysis of the quantitative diagnostic criteria for hysterosalpingography(HSG)in clinical trials.Methods Questionnaire survey method was used for this study.A test questionnaire scale was constructed based on the imaging data of 10 patients who had received HSG.Fifteen medical workers engaged in HSG-related clinical and scientific research work were invited to score the test questionnaire according to quantitative diagnostic criteria.Internal consistency testing,correlation analysis,and exploratory factor analysis were used to evaluate the reliability and validity of the quantified diagnostic criteria.Results The overall Cronbach's α coefficient for this quantitative diagnostic criteria was 0.834.The Cronbach's α coefficients for the three evaluation functions,including tubal patency,tubal adhesion and pelvic adhesion,were 0.722,0.627 and 0.724 respectively.The Spearman-Brown split-half reliability coefficient was 0.859,and the Guttman split-half coefficient was 0.830.The inter-rater reliability measured by the Kendall W coefficient was 0.806(P＜0.05).The analysis indicated that the evaluation function for pelvic adhesion was suitable for factor analysis(KMO value=0.573,Bartlett Spherical test P=0.003).Two common factors were extracted(characteristic root being set at 1),and the cumulative variance interpretation rate was up to 74.74％.These factors were named as"items with low ambiguity"and"items with potential ambiguity"respectively.Conclusion The overall reliability and validity of this quantitative diagnostic criteria are satisfactory,it can meet the requirements of HSG-related clinical trials and has the potential for clinical promotion.

Objective:To analyze the epidemiological and clinical characteristics of respiratory pathogens in China.Methods:This study was a cross-sectional study, which encompassed 19 core units of the clinical pathogen network and established a three-tiered clinical pathogen surveillance system. Thirty respiratory samples were collected every two weeks from various units from January to December 2024, and the clinical and pathogen diagnostic information were gathered. A total of 11 864 samples were tested using this system. The tier-1 clinical pathogen surveillance system covered influenza A virus (Flu-A), influenza B virus (Flu-B), respiratory syncytial virus (RSV), and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The tier-2 clinical pathogen surveillance system focused on 18 key respiratory pathogens. The tier-3 clinical pathogen surveillance system further clarified whether any emerging infectious diseases had occurred.Results:The tier-1 clinical pathogen surveillance system showed Flu-A predominated in December, Flu-B predominated in January, SARS-CoV-2 peaked in March and August, whereas RSV circulated sporadically throughout the year. Geographic trends were broadly consistent across the seven major regions, although Flu-A detection in December was notably higher in Northeast China (48.1%(111/231)) and East China (36.2%(148/409)), and RSV detection was concentrated in the Northwest and South China from January to March. Data from the tier-2 clinical pathogen surveillance system indicated that Streptococcus pneumoniae, Mycoplasma pneumoniae, rhinovirus, and adenovirus were detected year-round, of these, Streptococcus pneumoniae and rhinovirus showed elevated positive detection rates from August to September, while adenovirus peaked in January. Legionella pneumophila was not detected throughout the year, and other pathogens fluctuated throughout the year without a consistent pattern. The predominant etiologic agents of pediatric pneumonia were Mycoplasma pneumoniae (35.0%(105/300)), rhinovirus (25.7%(77/300)), and adenovirus (17.3%(52/300)), whereas adult pneumonia was mainly caused by Streptococcus pneumoniae (10.5%(29/277)), Staphylococcus aureus (6.9%(19/277)), Mycoplasma pneumoniae (6.9%(19/277)), and Flu-A (6.1%(17/277)). The tier-3 clinical pathogen surveillance system did not identify any emerging respiratory pathogens. Conclusion:Respiratory pathogens in China in 2024 exhibit distinct temporal and spatial distribution patterns and vary among different populations.

Objective : To explore the effect of esketamine on anxiety-depressive-like behavior in mice and its rela- tionship with inflammation． Methods : SPF grade healthy adult male C57BL/6J mice，weighing 20 －24 g，were used in the exprement．The random number table method was used to divide into 5 groups (n = 8) : control group ( Con group) ，esketamine group (ESK group) ，model group ( LPS group) ，model + esketamine prevention group (LPS + ESK1 group) and model + esketamine treatment group ( LPS + ESK2 group) ．An inflammation-induced anxiety-depression model was prepared by intraperitoneal injection of LPS 0. 83 mg / kg．The ESK group was injec- ted with esketamine 10 mg / kg ; LPS group was injected with LPS 0. 83 mg / kg ; LPS + ESK1 group was injected with LPS 0. 83 mg / kg before 24 hours intraperitoneal injection of esketamine 10 mg / kg ; and the LPS + ESK2 group was injected with LPS 0. 83 mg / kg and 30 minutes later with esketamine 10 mg / kg．24 h after intraperitoneal injec- tion of LPS，the anxiety-depression-like behaviors of mice were measured using behavioral experiments．At the end of behavioral experiments，the spleen was taken immediately ; hippocampal tissues were taken and enzyme-linked immunosorbent assay (ELISA) was used to detect the contents of interleukin-1 β (IL-1 β) ，tumor necrosis factor al- pha (TNF-α) and interleukin 6 (IL-6) and neuronal pathological changes in hippocampal tissues were observed by HE staining. Results : Compared with the Con group，mice in the LPS group showed increased anxiety and depres- sion-like behavior (P＜0. 05) ，increased spleen weight / body weight (P ＜0. 05 ) ，increased hippocampal tissue concentrations of IL-1 β , TNF-α and IL-6 (P＜0. 05) ，and increased neuronal degeneration necrosis，there was no statistically significant difference in these indicators in the ESK group compared with the Con group．Compared with the LPS group，mice in the LPS + ESK1 and LPS + ESK2 groups showed reduced anxiety-depression-like behavior (P＜0. 05) ，decreased splenic weight / body weight (P ＜0. 05) ，hippocampal tissue IL-1 β , TNF-α , IL- 6 con- centrations were reduced (P＜0. 05) ，and neuronal degeneration necrosis was reduced．Compared with the LPS + ESK1 group，the LPS + ESK2 group showed an increase in the distance travelled in the central area of the open field experiment and the distance into the open arm of the elevated cross maze experiment (P＜0. 05) ，a decrease in IL-6 and TNF-α concentrations (P＜0. 05) ，and a reduction in the degree of neuronal damage． Conclusion Esketamine ameliorates LPS-induced anxiety-depression-like behavior and neuronal damage in mice by a mechanism that may be related to reduced inflammation.

Objective To analyze risk factors for pulmonary vein obstruction (PVO) after intracardiac total anomalous pulmonary venous connection (TAPVC) repair. Methods A retrospective analysis of clinical data of the patients with intracardiac TAPVC who underwent surgery at our center from April 2009 to April 2019 was conducted. Kaplan-Meier curves were used to assess the risk of postoperative PVO. Logistic regression analysis was used to identify relevant risk factor for postoperative PVO. Results We finally included 169 patients. The median age at surgery was 89.0 (41.5, 195.0) days, and the median weight at surgery was 4.8 (3.8, 6.0) kg. The preoperative PVO rate was 18.3% (31/169). Post-repair PVO occurred in 8.9% (15/169) of the patients. The atresia of common pulmonary and subtype of coronary sinus/right atrium did not significantly affect the risk of PVO (P=0.053, P=0.330). Relevant risk factors included preoperative PVO (P<0.001) and the ratio of left ventricular end-systolic diameter to right ventricular diameter (P=0.025). Conclusion Surgical repair of intracardiac TAPVC has achieved satisfactory results in our center, but the long-term risk of obstruction should not be underestimated. An increased ratio of left ventricular end-systolic diameter to right ventricular diameter and preoperative PVO are associated with post-repair PVO.

Objective: To explore the effectiveness of healthy school canteen intervention on nutritional literacy, food consumption, as well as attitude towards school canteen. Methods: A primary school in Taizhou City was selected as the intervention school, and another comparable primary school was selected as the control one. A total of 320 students (163 in the intervention group and 157 in the control group) received a comprehensive intervention based on the construction of a healthy school canteen in the school,incluling healthy dining environment,food impravement,chef training,nutrition and health education, while the control group did not receive any intervention. Questionnaires survey was administered to both groups before and after the intervention. Results: Before the intervention, no significant differences were found in the total scores of skills and nutrition literacy, frequency of food intake, behaviors and attitudes related to canteen construction between the two groups( P >0.05). Daily intake of vegetables, dairy products, fish/poultry/eggs/lean meat increased by 19.63, 15.95 and 19.63 percentage point respectively ( χ 2=15.25，9.14，13.93， P <0.01). The proportion of students reporting have read related intervention materials in the intervention group(95.71%) was higher than the control group(84.71%) ( χ 2= 11.04, P < 0.01 ). The students in favor of low salt, low oil and low sugar dishes in the intervention group (74.85%) was higher than in the control group(48.41%) ( χ 2=23.73, P <0.01). Conclusion Based on the comprehensive intervention of nutrition and health canteens can improve students nutrition literacy and dietary structure. It is recommended to adopt the form of "home school linkage" to carry out the construction of large sample, multi regional and long term nutrition and health canteens.

The kidney is the body's most important organ and the protein components in urine could be detected for diagnosing certain diseases. The amount of IgG protein in urine could be used to determine the degree of kidney function damage. IgG protein in human urine was detected by vertical flow paper-based microfluidic chip, double-antibody sandwich immunoreaction, and cell phone image processing. The results showed that using an IgG antibody concentration of 500 μg/mL and a gold standard antibody concentration of 100 μg/mL, the image signal showed a good linear relationship in the range of IgG concentration of 0.2-3.2 μg/mL, with R²=0.973 3 achieved. A complete set of detection devices were designed and the detection method showed good non-specificity.
