Objective To investigate the incidence trend of infectious diseases among kindergarten children in Yangpu District, Shanghai, and to provide scientific reference for prevention and control strategies of infectious diseases among key populations. Methods Descriptive epidemiology method and Joinpoint regression analysis model were used to analyze the surveillance data of infectious diseases among kindergarten children. Results The average annual reported incidence of infectious diseases among kindergarten children in Yangpu District was 3,344.08/100,000, showing a downward trend (AAPC=-5.51, 95%CI: -13.02~2.63). Intestinal (65.49%) and respiratory (34.48%) infectious diseases were the main cases. There were 7,378 cases of hand, foot and mouth disease (62.95%), 1,885 cases of influenza (16.08%), 1,378 cases of varicella (11.76%), and 392 cases of mumps (3.34%), accounting for 94.14% of all reported cases. Hand, foot and mouth disease (AAPC=-17.68%, 95%CI: -27.52~-6.51), mumps (AAPC=-9.33, 95%CI: -14.86~-3.45) and varicella (AAPC=-7.32, 95%CI: -17.35~3.93) showed an overall decreasing trend, while influenza (AAPC=32.19, 95%CI: 12.49-55.34) was on the rise. The incidence of the disease showed double peak distribution, and the high incidence months were from May to July and from September to December. The male to female ratio was 1.39:1. Conclusion The incidence of infectious diseases among kindergarten children in Yangpu District shows a downward trend. It is necessary to continue to increase the coverage rate of Enterovirus 71(EV71), influenza, chickenpox and MMR combined live attenuated vaccine, strengthen monitoring and early warning, actively carry out health guidance, and effectively control the occurrence of common infectious diseases in kindergarten children.

ObjectiveTo investigate the molecular mechanism of kaempferol-induced apoptosis in hepatic stellate cells (HSC) via the mitochondrial pathway. MethodsHSC were divided into five groups: blank control, transforming growth factor-β1(TGF-β1) (10 ng/mL) group, and groups treated with different concentrations of kaempferol (8, 16, 32 µmol/L). Cell counting kit-8(CCK-8) assay was used to evaluate chrysin's effect on HSC proliferation. Transwell assay was used to assess chrysin's impact on HSC migration. Flow cytometry was used to detect apoptosis, reactive oxygen species (ROS) expression, and mitochondrial permeability transition pore (mPTP) opening across groups. 5,5′,6,6′-Tetrachloro-1,1′,3,3′-tetraethylimidacarbocyanine iodide (JC-1) assay was used to test mitochondrial membrane potential. Western blot analysis was performed to determine the expression levels of mitochondrial apoptosis-associated proteins, namely B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax), Cleaved-Caspase3, Cleaved-Caspase9, and sirtuin 3 (SIRT3). Transmission electron microscopy was used to examine mitochondrial structural alterations. Molecular docking and kinetic simulations were used to analyze the targeted interaction between kaempferol and NAD-dependent deacetylase sirtuin-3 (SIRT3). ResultsCompared with the blank control group: in the TGF-β1 group, HSC proliferation and migration rates increased (P<0.01), ROS levels and mPTP opening both increased (P<0.05), the JC-1 red/green fluorescence ratio increased (P<0.01), and the expression of Cleaved-Caspase-3, Cleaved-Caspase-9 and Bcl-2 increased (P<0.05), whilst SIRT3 expression decreased (P<0.01); the number of mitochondria increased (P<0.05), and mitochondrial length decreased (P<0.01). Compared with the TGF-β1 group: treatment with all groups of kaempferol reduced HSC proliferation and migration rates (P<0.01), whilst simultaneously increasing the HSC apoptosis rate (P<0.01); HSC ROS levels and mPTP opening both increased (P<0.05); the JC-1 red/green fluorescence ratio decreased (P<0.01), and the expression levels of Bax, Cleaved-Caspase-3 and Cleaved-Caspase-9 were upregulated (P<0.01), whilst the expression levels of Bcl-2 and SIRT3 were downregulated (P<0.01), and the number of mitochondria increased (P<0.05); mitochondrial length was reduced (P<0.01). Molecular docking and dynamics simulations revealed that the docking energy for kaempferol with SIRT3 was 108.89 kcal/mol; the RMSD curve stabilized after 20 ns; and RMSF analysis indicated that most residues exhibited minimal fluctuations. ConclusionKaempferol induces HSC apoptosis through the mitochondrial pathway, potentially via targeting SIRT3 and disrupting mitochondrial function.

OBJECTIVE To analyze the incidence of cyclosporine (CsA)-associated acute kidney injury (AKI) in hospitalized patients, identify influencing factors, and construct a risk prediction model. METHODS A single-center retrospective study was conducted, enrolling clinical data from hospitalized patients treated with CsA at the First Affiliated Hospital of Shandong First Medical University & Shandong Provincial Qianfoshan Hospital from January 2018 to July 2024. The patients were classified into AKI group and non-AKI group based on the occurrence of CsA-related AKI. Univariate analysis and multivariate Logistic regression analysis were used to identify independent risk factors for CsA-related AKI, and a risk prediction model was constructed and its performance was evaluated. RESULTS A total of 439 patients were included, of whom 54 developed CsA-related AKI, with an incidence rate of 12.30%. The occurrence of CsA-associated AKI was positively correlated with concurrent bacterial pulmonary infection, cytomegalovirus viremia, respiratory failure, renal insufficiency, gastrointestinal bleeding, and peripheral central venous catheterization (odds ratios of 763.750, 16.944, 41.933, 236.806, 17.537 and 212.789, respectively; P <0.05); while uric acid, prealbumin, and calcium levels were negatively associated with it (odds ratios of 0.983, 0.967 and 0.058, respectively; P <0.05). The prediction model constructed based on the above factors yielded a χ 2 value of 10.254 ( P >0.05) in the Hosmer-Lemeshow test. The average area under the curve (AUC) from 10-fold cross-validation was 0.885. The AUC of the receiver operating characteristic curve was 0.883, with a sensitivity of 84.3% and a specificity of 80.4%, respectively, at the optimal cutoff value of 0.1. CONCLUSIONS Six factors, including concurrent bacterial pulmonary infection and cytomegalovirus viremia, are positively associated with the occurrence of CsA-related AKI; while uric acid, prealbumin, and calcium levels are negatively associated. The Logistic regression model constructed based on these factors demonstrates good predictive performance and can assist clinic in conducting early risk assessment and personalized interventions.

Objective:To investigate the assoication of amino acid metabolism levels with severity of diabetic peripheral neuropathy(DPN) in patients with type 2 diabetes mellitus.Methods:A retrospective analysis was conducted on 118 patients with type 2 diabetes mellitus who were admitted to Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from January to April 2021. Patients were divided into groups according to the Toronto Clinical Scoring System(TCSS), and amino acid profiling was performed. General demographics and biochemical indicators of each group were collected to analyze the relationship between DPN severity and amino acid metabolism.Results:As TCSS scores increased, patients were older and had a longer duration of diabetes. Statistically significant differences in leucine, isoleucine, tryptophan, and phenylalanine levels were observed among the four groups. After adjusting for confounding variables using covariance analysis, when the TCSS score was≥13, the serum phenylalanine level was significantly elevated, and the difference was statistically significant( P<0.05). Multivariate linear regression analysis indicated that TCSS score was an influencing factor for phenylalanine levels( P=0.010). Multivariate logistic regression analysis demonstrated that higher serum phenylalanine levels correlated with higher TCSS scores( OR=1.047, 95% CI 1.011-1.083, P=0.010). Receiver operating characteristic(ROC) curve analysis revealed that serum phenylalanine and the difference between phenylalanine and tryptophan had diagnostic value for severe DPN patients, with areas under the ROC curve of 0.673(95% CI 0.553-0.793, P=0.006) and 0.746(95% CI 0.641-0.852, P<0.001) respectively. Conclusions:The levels of phenylalanine and tryptophan in the serum of patients with type 2 diabetes mellitus are correlated with the severity of DPN. These findings suggest that serum phenylalanine, tryptophan, or their metabolic products may be involved in the pathogenesis and progression of DPN.

The clinical antiprotozoal drug nitazoxanide has been demonstrated to improve the experimental diabetes mellitus, lipid metabolism disorders, atherosclerosis and inhibit inflammation. Since the pathogenesis of heart failure with preserved ejection (HFpEF) is multifactorial and closely associated with the aforementioned diseases, we aim to study the effect of nitazoxanide on high-fat diet (HFD) plus L-NAME (N ω-nitro-l-arginine methyl ester)-induced HFpEF and metabolic syndrome in mice. We found that oral nitazoxanide improved cardiac hypertrophy, cardiac fibrosis, cardiac diastolic dysfunction, increased blood pressure, impaired exercise tolerance, impaired glucose handling, serum lipid disorders, hepatic steatosis, increased weight of white adipose tissues and kidney fibrosis in HFD + L-NAME-treated mice. In the established HFD + L-NAME-induced HFpEF and metabolic syndrome mouse model, therapeutic treatment with nitazoxanide rescued HFD + L-NAME-induced pathological phenotypes as mentioned above. The in vitro experiments revealed that tizoxanide, the active metabolite of nitazoxanide, increased the basal mitochondria metabolism of cardiomyocytes, inhibited cardiomyocyte hypertrophy and collagen secretion from cardiac fibroblasts, and relaxed phenylephrine- and U46619-induced constriction of rat mesenteric arteries, indicating that the direct effect of tizoxanide might partly contribute to the protective effect of nitazoxanide against HFpEF in vivo. The present study suggests that nitazoxanide might be a potential drug for HFpEF and metabolic syndrome therapy.

ObjectiveTo evaluate the clinical efficacy of Fuzheng Huaji Formula (扶正化积方) for chronic hepatitis B to reduce the incidence of liver cirrhosis and hepatocellular carcinoma. MethodsA retrospective cohort study was conducted, collecting medical records of 118 patients with chronic hepatitis B and 234 patients with hepatitis B-related cirrhosis who visited the hospital between January 1, 2014, and December 31, 2018. The use of Fuzheng Huaji Formula was designated as the exposure factor. Patients receiving antiviral treatment for hepatitis B without concurrent Fuzheng Huaji Formula therapy were included in the western medicine group, while those receiving antiviral treatment combined with Fuzheng Huaji Formula for a cumulative treatment lasting longer than 3 months were included in the combined treatment group. The follow-up observation period was five years. Kaplan-Meier survival analysis was used to assess the cumulative incidence of cirrhosis in patients with chronic hepatitis B and the cumulative incidence of hepatocellular carcinoma in patients with hepatitis B-related cirrhosis. Univariate and multivariate Cox regression analyses were employed to examine the factors influencing the occurrence of cirrhosis and hepatocellular carcinoma. ResultsAmong patients with chronic hepatitis B, there were 55 cases in the combined treatment group and 63 cases in the western medicine group; among patients with hepatitis B-related cirrhosis, there were 110 cases in the combined treatment group and 124 cases in the western medicine group. Five-year follow-up outcomes for chronic hepatitis B patients showed that the cumulative incidence of cirrhosis was 5.45% (3/55) in the combined treatment group and 17.46% (11/63) in the western medicine group, with a statistically significant difference between groups (Z = 2.003, P = 0.045). Five-year follow-up outcomes for hepatitis B-related cirrhosis patients showed that the cumulative incidence of hepatocellular carcinoma was 8.18% (9/110) in the combined treatment group and 22.58% (28/124) in the western medicine group, also showing a statistically significant difference (Z = 3.007, P = 0.003). Univariate and multivariate Cox regression analyses indicated that treatment with Fuzheng Huaji Formula is an independent protective factor in preventing the progression of chronic hepatitis B to cirrhosis and the progression of hepatitis B-related cirrhosis to hepatocellular carcinoma (P<0.05). ConclusionCombining Fuzheng Huaji Formula with antiviral therapy for hepatitis B can effectively intervene in the disease progression of chronic hepatitis B, reducing the incidence of cirrhosis and hepatocellular carcinoma.

With the continuous advancement of neuroimaging technologies, clinical research has discovered the phenomenon of cognitive-motor dissociation in patients with disorders of consciousness (DoC). This groundbreaking finding has provided new impetus for the development and application of brain-computer interface (BCI) in clinic. Currently, BCI has been widely applied in DoC patients as an important tool for assessing and assisting behaviorally unresponsive individuals. This paper reviews the current applications of BCI in DoC patients, focusing four main aspects including consciousness detection, auxiliary diagnosis, prognosis assessment, and rehabilitation treatment. It also provides an in-depth analysis of representative key techniques and experimental outcomes in each aspect, which include BCI paradigm designs, brain signal decoding method, and feedback mechanisms. Furthermore, the paper offers recommendations for BCI design tailored to DoC patients and discusses future directions for research and clinical practice in this field.

Objective:
To investigate the correlations among clinicopathological features, histopathological growth patterns and prognosis of extrapulmonary multiple metastatic(stage ⅣB) pulmonary adenocarcinoma with epidermal growth factor receptor(EGFR) mutations.
Methods :
A total of 488 eligible patients with adenocarcinoma of stage ⅣB. Clinicopathological data,EGFRgene mutation subtypes, metastatic sites, histopathological growth patterns and survival information were collected. The chi-square test(χ2test) and Fisher's exact probability method were used to detect the correlation between the metastasis status and various clinical characteristics; the Kaplan-Meier method was used to conduct survival analysis on the median Progression-Free Survival(PFS) under different clinical characteristics. Cox univariate and multivariate regression analyses were conducted to evaluate the impact of various clinical characteristics on prognosis.
Results :
The metastatic patterns of stage ⅣB pulmonary adenocarcinoma withEGFRmutations was correlated with histopathological growth patterns(P<0.05). In the group with multiple metastases in a single organ, the proportion of micropapillary type in the group with multiple metastases in a single organ was higher than that in the group with multiple-organ metastases(51.1%vs41.1%), while the proportion of solid type in the group with multiple-organ metastases was higher than that in the group with multiple metastases in a single organ(23.8%vs14.2%). Multiple brain or multiple bone metastases were correlated with histopathological growth patterns and tumor differentiation degree. Compared with the multiple bone metastases group, the proportion of acinar type decreases in the multiple brain metastasis group, while the proportion of micropapillary type increased. Moreover, the proportion of poorly differentiated tumors increased significantly(P<0.05). Compared with multiple bone metastases, the proportion of poorly differentiated tumors significantly increases in the group with multiple brain metastases. The median progression-free survival(PFS) of patients with a predominant solid growth pattern was shorter than that of patients with other growth patterns(12.7 monthsvs17.8 months,P<0.05). The PFS of patients in the poorly differentiated group was worse than that in the moderately differentiated group(15.6 monthsvs17.8 months,P<0.05). There were significant differences in PFS among patients with common sensitive mutations and rare mutationsEGFR(17.3 monthsvs10.2 months,P<0.01). Cox proportional hazards regression model suggested that solid growth pattern, poor differentiation and rare single gene mutation were adverse prognostic factors.
Conclusion
In stage ⅣB pulmonary adenocarcinoma patients withEGFRmutations, both the metastatic patterns and metastatic sites are significantly correlated with the histopathological growth patterns of tumors. Moreover, theEGFRmutation subtypes as well as the histopathological growth patterns and differentiation degree of tumors significantly affect the prognosis of patients.
