Objective To investigate the value of serum and sputum Galectin-7 expression in evaluating the therapeutic effect of omalizumab in children with moderate asthma.Methods A total of 210 children with moderate asthma admitted to the hospital from January 2021 to August 2023 were selected as the study ob-jects.All the children were treated with omazumab,and the efficacy was evaluated according to the clinical control criteria of asthma,and they were divided into effective group and ineffective group.The expression of Galectin-7 in serum and sputum before treatment was detected in the two groups.Multivariate Logistic regres-sion was used to analyze the relationship between serum and sputum Galectin-7 and the efficacy of omalizumab in the treatment of moderate asthma children.Receiver operating characteristic(ROC)curve was used to ana-lyze the value of serum and sputum Galectin-7 in evaluating the efficacy of omalizumab in the treatment of children with moderate asthma.Results There was statistical significance in the proportion of passive smok-ing between the two groups(P＜0.05).The expression of Galectin-7 in serum and sputum before treatment in the effective group was lower than that in the ineffective group,and the difference was statistically signifi-cant(P＜0.05).Multivariate Logistic regression analysis showed that passive smoking history,serum Galec-tin-7 expression and sputum Galectin-7 expression were independent risk factors affecting the efficacy of oma-lizumab in the treatment of moderate asthma children(P＜0.05).ROC curve analysis results showed that,The area under the curve of serum Galectin-7,sputum Galectin-7 and their combination to evaluate the efficacy of omalizumab in the treatment of children with moderate asthma were 0.791(95％CI:0.673-0.849),0.845(95％CI:0.766-0.925),0.910(95％CI:0.844-0.976),respectively.Conclusion The combined detection of serum Galectin-7 and sputum Galectin-7 has a higher value in evaluating the therapeutic effect of omazumab in children with moderate asthma.

Objective To explore the influencing factors of immune-associated thyroid dysfunction caused by sintilimab treatment in solid tumors and construct a prediction model.Methods Medical records of patients diagnosed with solid tumors and treated with sintilimab at Peking University People's Hospital(Xizhimen Campus,Tongzhou Campus,Shijiazhuang Campus)from January 2023 to September 2024 were collected to explore the influencing factors that caused immune-related thyroid dysfunction using univariate and multifactorial binary logistic regression analyses and to establish a prediction model.The predictive effect of the model was assessed using the receiver operating characteristic(ROC)curve.Results A total of 120 patients were included,and 33 presented with immune-related thyroid dysfunction.Multifactorial logistic regression analysis revealed that thyroid-stimulating hormone(TSH)[OR=2.470,95%CI=(1.279,4.771)]and treatment cycles[OR=1.298,95%CI=(1.117,1.509)]were independent risk factors for the occurrence of immune-associated thyroid dysfunction,and the difference was statistically significant(P＜0.05).The area under the ROC curve was(0.897±0.043)[95%CI=(0.813,0.981)],the Yoden index was 0.703,and the model prediction accuracy was 86.5%.Conclusion The risk of immune-related thyroid dysfunction caused by sintilimab is high,and TSH and treatment cycle are the influencing factors,and the constructed model has certain predictive value and is of reference significance.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

Hepatic encephalopathy (HE) is a kind of neuropsychiatric syndrome caused by acute or chronic liver failure or portosystemic venous shunt (hereinafter referred to as portosystemic shunt), which can lead to the occurrence of functional impairment, personality and behavioral abnormalities, coma, and even death. Most patients with cirrhosis combined with HE have spontaneous portosystemic shunt (SPSS), especially those with recurrent or persistent HE. Internal medicine's current standard of treatment for HE associated with SPSS in cirrhotic patients is unsatisfactory, and even after treatment, recurrent HE episodes may still occur. Although interventional therapy has shown significant results and has been applied in clinical practice for many years for SPSS-associated HE, the number of treatment-related cases is relatively small, and there is a lack of large samples and well-designed research. Currently, interventional therapy for SPSS-associated HE in patients with cirrhosis is still under continuous exploration.

China now has the largest number of people living with diabetes worldwide. To address such a burden, the Healthy China 2030 initiative and subsequent Healthy China Initiative-Diabetes Prevention and Treatment Action Plan(2024-2030)were launched. A shift from " disease-centred" approach to " health-centred" approach and from treatment to prevention is the core of diabetes management in China. Various regions have formed some characteristic prevention and control models with local features in their long-term diabetes prevention and control work, such as the " Community Three-in-One" management model, hospital-community integrated prevention and control model, " Three Doctors Shared Management" model, and family doctor model. Based on the description of the current situation of diabetes prevention and control in China, this article elaborates on the diabetes prevention and control model, key measures, and practical effects in Bao′an District, Shenzhen. It aims to introduce the practices and reflections on diabetes prevention and control in Bao′an, Shenzhen, and provide experiential reference for diabetes prevention and control in other areas.

Objective To explore the possible influencing factors of secondary diarrhea in pediatric inpatients with pneumonia. Methods A total of 122 pediatric inpatients with pneumonia who developed secondary diarrhea, admitted to the Department of Pediatrics at the First Hospital of Qinhuangdao, Hebei Province, from January 2019 to March 2024, were selected as the case group. Another 266 pediatric inpatients with pneumonia admitted during the same period who did not develop secondary diarrhea were selected as the control group. Basic information such as gender, age, length of hospital stay, and fever reduction time of the pediatric inpatients with pneumonia was collected. Additionally, binT lymphocyte subpopulations and intestinal flora-related indicators were tested. Univariate analysis and unconditional logistic regression multivariate analysis were used to analyze the possible influencing factors of secondary diarrhea in pediatric inpatients with pneumonia. Results The multivariate results showed that after adjusting for gender, the risk of secondary diarrhea in pediatric inpatients with pneumonia decreased to 90.8% of the original risk with each additional year of age (OR=0.908, 95% CI=0.869-0.948, P<0.001). For every 1 CFU/g increase in the number of Bifidobacterium colonies, the risk of secondary diarrhea decreased to 91.6% of the original risk (OR=0.916, 95% CI=0.865-0.969, P<0.001). For every 1 CFU/g increase in the number of Lactobacillus colonies, the risk decreased to 91.1% of the original risk (OR=0.911, 95% CI=0.881-0.942, P<0.001). For every 1 CFU/g increase in the number of Enterococcus colonies, the risk decreased to 91.5% of the original risk (OR=0.864, 95% CI=0.864-0.968, P<0.001). Conclusions Age, the number of Bifidobacterium colonies, the number of Lactobacillus colonies, and the number of Enterococcus colonies are independent influencing factors of secondary diarrhea in pediatric inpatients with pneumonia.

Objective To develop novel metformin carbon dots(MCDs)with superior performance to enhance the osteogenic differentiation potential of human periodontal ligament stem cells(hPDLSCs)under inflammatory conditions.Methods Three types of MCDs-MCDsCA,MCDsAA,and MCDsCS were synthesized via a one-step hydrothermal method using metformin(Met)in combination with citric acid(CA),ascorbic acid(AA),and carboxymethyl chitosan(CS),respectively.Their physicochemical properties were characterized by transmission electron microscopy(TEM),Fourier-transform infrared spectroscopy(FTIR),and UV-visible spectrophotometry.The biocompatibility and cellular uptake of the MCDs were assessed using CCK-8 assay and confocal laser scanning microscopy.Alkaline phosphatase(ALP)staining and ALP activity assay were conducted to identify the most effective MCDs type in promoting osteogenic differentiation of hPDLSCs under inflammatory conditions.Subsequently,ALP and Alizarin Red S(ARS)staining,qRT-PCR,and Western blotting were performed to assess the effects of the optimal concentration of MCDsCS and its raw material(Met+CS)on osteogenic differentiation under inflammatory conditions.Results All 3 types of nanoscale MCDs exhibited favorable physicochemical characteristics and biocompatibility,and could be effectively internalized by hPDLSCs.Both MCDsCA and MCDsAA significantly promoted hPDLSCs proliferation at lower concentrations(0～0.50 mg/mL),while MCDsCS exhibited excellent cytocompatibility over a broader range(0～2.00 mg/mL).Under inflammatory conditions,MCDsCA and MCDsAA showed no significant effect on ALP expression in hPDLSCs,whereas MCDsCS significantly enhanced ALP expression in a dose-dependent manner,with the optimal effect observed at 0.10 mg/mL(P<0.05).Compared to Met+CS,0.10 mg/mL MCDsCS significantly enhanced ALP expression and calcium nodule formation under inflammatory conditions.It also upregulated the expression of osteogenesis-related genes(ALP,RUNX2,COL-1,OCN)and proteins(ALP,RUNX2,OCN)(P<0.01),while reducing the levels of inflammatory cytokines IL-1β and IL-6(P<0.01).Conclusion A novel MCDsCS with sound biocompatibility is successfully developed,and can effectively promote osteogenic differentiation of hPDLSCs and exerts anti-inflammatory effects under inflammatory conditions,indicating its potential as a nanotherapeutic agent for periodontitis-associated bone regeneration.

Ischemic stroke (IS) is a globally life-threatening disease. Presently, few therapeutic medicines are available for treating IS, and rt-PA is the only drug approved by the US Food and Drug Administration (FDA) in the US. In fact, many agents showing excellent neuroprotection but no blood flow-improving activity in animals have not achieved ideal clinical efficacy, while thrombolytic drugs only improving blood flow without neuroprotection have limited their wider application. To address these challenges and meet the huge unmet clinical need, we have designed and identified a novel compound AAPB with dual effects of neuroprotection and cerebral blood flow improvement. AAPB significantly reduced cerebral infarction and neural function deficit in tMCAO rats, pMCAO rats, and IS rhesus monkeys, as well as displayed exceptional safety profiles and excellent pharmacokinetic properties in rats and dogs. AAPB has now entered phase I of clinical trials fighting IS in China.
