ObjectiveTo investigate the effects of Yueju Wan on the 5-hydroxytryptamine （5-HT） signaling pathway in rats with functional dyspepsia （FD） and to explore its therapeutic mechanism in the treatment of FD. MethodsSixty Sprague-Dawley （SD） rats were randomly divided into a normal group， model group， mosapride group （1.575 mg·kg^-1）， and Yueju Wan low-， medium-， and high-dose groups （0.735， 1.47， and 2.94 g·kg^-1， respectively）. The FD rat model was established using GUO's tail-clamping stimulation combined with irregular feeding. After 14 days of modeling， rats were administered the corresponding drugs by gavage for 28 days. After treatment， gastric emptying rate and small intestinal propulsion rate were measured. Serum levels of 5-HT， tryptophan hydroxylase （TPH）， and substance P （SP） were detected by enzyme-linked immunosorbent assay （ELISA）， and acetylcholine （ACh） levels were determined by chemical methods. Histopathological changes in the gastric antrum were observed using hematoxylin-eosin （HE） staining. Real-time quantitative polymerase chain reaction （Real-time PCR） and Western blot were used to assess the mRNA and protein expression levels of 5-hydroxytryptamine 4 receptor （5-HT4R）， SP， and acetylcholinesterase （AChE） in colon tissue， as well as 5-hydroxytryptamine 3 receptor （5-HT3R）， SP， and AChE in hypothalamic tissue. Immunohistochemistry （IHC） was used to examine the expression of 5-HT and 5-HT4R in the colon and 5-HT and 5-HT3R in the hypothalamus. ResultsCompared with the normal group， the gastric emptying rate and small intestinal propulsion rate in the model group were significantly decreased （P<0.01）. Serum levels of 5-HT， SP， ACh， and TPH were significantly reduced （P<0.01）. Histopathological examination revealed irregular arrangement of glands in the gastric antrum， slight mucosal atrophy， and mild inflammatory cell infiltration. The mRNA and protein expression levels of 5-HT4R， SP， and AChE in colon tissue， as well as 5-HT3R， SP， and AChE in hypothalamic tissue， were significantly decreased （P<0.01）， and 5-HT protein expression in both the colon and hypothalamus was also significantly reduced （P<0.01）. Compared with the model group， all Yueju Wan groups showed significantly increased gastric emptying rate and small intestinal propulsion rate （P<0.01）. The glands in the gastric antrum were more regularly arranged， with no inflammatory cell infiltration observed. Serum levels of 5-HT， SP， ACh， and TPH were significantly increased （P<0.01）. The mRNA and protein expression levels of 5-HT4R， SP， and AChE in colon tissue and 5-HT3R， SP， and AChE in hypothalamic tissue were significantly upregulated （P<0.05， P<0.01）， and 5-HT protein expression in both the colon and hypothalamus was significantly increased （P<0.01）. ConclusionYueju Wan has preventive and therapeutic effects on FD， and its mechanism may be related to regulation of the 5-HT signaling pathway， promotion of brain-gut peptide secretion， and enhancement of gastric motility.

Chaihu Guizhi Ganjiangtang was first recorded in the Treatise on Cold Damage （Shang Han Lun）. This prescription is composed of Bupleuri Radix， Scutellariae Radix， Cinnamomi Ramulus， Zingiberis Rhizoma， Trichosanthis Radix， Ostreae Concha， and Glycyrrhizae Radix et Rhizoma. It has the effects of soothing Lesser Yang， warming the spleen， and stimulating the generation of body fluid. It is mainly used to treat digestive tract diseases such as chronic cholecystitis （CC）， irritable bowel syndrome， and non-alcoholic fatty liver disease. Dyspepsia caused by CC presents a variety of gastrointestinal symptoms such as abdominal pain， poor appetite， postprandial fullness， aversion to greasy food， soft stool， and bitter mouth， being a type of biliary dyspepsia. In modern medicine， dyspepsia caused by CC is mainly managed by medical treatment and surgical treatment. Internal medicine mainly focuses on reducing inflammation， promoting the function of gallbladder， resolving stones， alleviating spasms， and relieving the pain for CC， demonstrating definite short-term efficacy but suffering from single effects， high recurrence rate， and poor compliance. Although surgical treatment can cure cholecystitis， it is accompanied by the increased incidence of adverse events such as abdominal pain， diarrhea， and dyspepsia. Modern clinical studies have confirmed that Chaihu Guizhi Ganjiangtang can significantly alleviate the symptoms such as abdominal pain and dyspepsia of CC patients. Pharmacological studies have found that Chaihu Guizhi Ganjiangtang mainly contains active ingredients such as Bupleuri Radix saponins， baicalin， cinnamaldehyde， gingerol， Trichosanthis Radix polysaccharide， Ostreae Concha polysaccharide， and Glycyrrhizae Radix et Rhizoma total flavonoids. Chaihu Guizhi Ganjiangtang can ameliorate the symptoms of dyspepsia caused by CC by inhibiting inflammatory responses， improving gallbladder contraction and gastrointestinal motility， regulating the bile acid-intestinal flora axis and the brain-gut axis， and modulating blood lipids through multiple targets. By reviewing the previous literature， this article summarizes the research progress in the treatment of dyspepsia caused by CC with Chaihu Guizhi Ganjiangtang and its main active ingredients as well as the pathogenesis of this disease and puts forward the shortcomings and improvement strategies for the current research. The review aims to provide a reference for the further research on Chaihu Guizhi Ganjiangtang in the treatment of dyspepsia caused by CC.

ObjectiveTo investigate the role and underlying mechanism of the Wnt/β-catenin signaling pathway in the process of Xiaojinwan （XJW）-containing serum interfering with endothelial-mesenchymal transition （EMT） in human breast cancer MDA-MB-231 cells. MethodsXJW-containing serum was prepared by intragastric administration of XJW （4 g·kg^-1） to SD rats. MDA-MB-231 cells were cultured in vitro. β-Catenin overexpression and knockdown plasmids were constructed and transfected into MDA-MB-231 cells. The optimal XJW-containing serum （4 g·kg^-1） according to previous studies was used for β-catenin intervention and overexpression experiments. The groups for intervention/overexpression experiments included intervention/overexpression blank group， β-catenin intervention/overexpression group， intervention/overexpression blank + XJW group， and β-catenin intervention/overexpression + XJW group. Cell morphology was observed under a microscope. Flow cytometry was used to detect and record apoptosis rates. Western blot was performed to measure apoptosis-related proteins ［B-cell lymphoma 2 （Bcl-2）， Bcl-2-associated X protein （Bax）， and active-Caspase-3］ and EMT-related proteins （E-cadherin， N-cadherin， and vimentin）. Real-time polymerase chain reaction （Real-time PCR） was used to detect β-catenin mRNA expression levels in different groups. ResultsIntervention experiment results showed that compared with the intervention blank group， the β-catenin intervention group and the intervention blank + XJW group showed increased apoptosis rates （P<0.05， P<0.01）， elevated protein levels of Bax， active Caspase-3， and E-cadherin （P<0.05， P<0.01）， and decreased protein levels of Bcl-2 and Vimentin （P<0.05， P<0.01）. β-catenin mRNA expression was reduced in the β-catenin intervention group （P<0.05， 0.63 ± 0.15） and the intervention blank + XJW group （P<0.05， 0.79 ± 0.33）. Compared with the β-catenin intervention group， the β-catenin intervention + XJW group exhibited an increased apoptosis rate （P<0.01）， elevated Bax and active Caspase-3 protein levels （P<0.05， P<0.01）， and decreased Bcl-2， N-cadherin， and Vimentin protein levels （P<0.05）. β-catenin mRNA expression was further reduced in the β-catenin intervention + XJW group （P<0.01， 0.22 ± 0.08）. Compared with the intervention blank + XJW group， the β-catenin intervention + XJW group showed an increased apoptosis rate （P<0.01）， elevated Bax， active Caspase-3， and E-cadherin protein levels （P<0.05， P<0.01）， and decreased Bcl-2， N-cadherin， and vimentin protein levels （P<0.05， P<0.01）. β-catenin mRNA expression was also reduced （P<0.05）. Overexpression experiment results showed that compared with the overexpression blank group， the β-catenin overexpression group exhibited a reduced apoptosis rate （P<0.01）， while the overexpression blank + XJW group showed an increased apoptosis rate （P<0.05）. In the β-catenin overexpression and β-catenin overexpression + XJW groups， Bax and E-cadherin protein levels decreased （P<0.05， P<0.01）， while Bcl-2， N-cadherin， and vimentin levels increased （P<0.05）. In the overexpression blank + XJW group， Bax and E-cadherin levels increased （P<0.05， P<0.01）， while Bcl-2， N-cadherin， and vimentin levels decreased （P<0.05， P<0.01）. β-catenin mRNA expression increased in the β-catenin overexpression group （P<0.01， 7.26 ± 1.03） but decreased in the overexpression blank + XJW group （P<0.05， 0.73 ± 0.14）. Compared with the β-catenin overexpression group， the β-catenin overexpression + XJW group showed an increased apoptosis rate （P<0.01）， elevated Bax and E-cadherin levels （P<0.05）， and decreased N-cadherin and vimentin levels （P<0.05）. β-catenin mRNA expression was reduced （P<0.05， 4.65 ± 1.02）. Compared with the overexpression blank + XJW group， the β-catenin overexpression + XJW group exhibited a reduced apoptosis rate （P<0.01）， decreased Bax and E-cadherin levels （P<0.01）， and increased Bcl-2， N-cadherin， and Vimentin levels （P<0.05）. β-catenin mRNA expression increased （P<0.01）. ConclusionXJW-containing serum inhibits breast cancer cell proliferation by suppressing EMT， which is associated with the regulation of the Wnt/β-catenin pathway.

Background Attention-deficit/hyperactivity disorder (ADHD) is one of the most common neurodevelopmental disorders in children and adolescents. Current research suggests that environmental factors, such as per- and polyfluoroalkyl substances (PFAS), may be associated with an increased risk of ADHD in offspring. However, most epidemiological evidence originates from non-Chinese populations, with limited research investigating the association between prenatal PFAS and ADHD-like symptoms in Chinese school-aged children. Objective To examine the association between prenatal PFAS exposure and ADHD-like symptoms in 7-year-old children. Methods Based on the Shanghai Birth Cohort, this study included 488 mother-child pairs. PFAS were measured in maternal serum during the second trimester using ultra-performance liquid chromatography-tandem mass spectrometry. The analysis focused on eight specific compounds from three PFAS categories [perfluorooctanoic acid (PFOA), perfluorooctanesulfonic acid (PFOS), and perfluorohexanesulfonic acid (PFHxS)]. The hyperactivity subscale of the Strengths and Difficulties Questionnaire (SDQ) was used to assess ADHD-like symptoms in children at age 7. Basic demographic information was collected via questionnaires and medical records. Negative binomial regression models were used to evaluate the relationship between individual exposures to the three typical PFAS categories (PFOA, PFOS, and PFHxS) and children's ADHD-like symptoms, while the bayesian kernel machine regression (BKMR) mixture model was employed to assess the overall effect of PFAS mixture exposure on ADHD-like symptoms. Results The detection rates of the eight target PFAS in maternal second-trimester serum were all above 85%, with PFOA exhibiting the highest median concentration (10.21 ng·mL⁻¹). Overall, 14.75% of the children exhibited ADHD-like symptoms. Results from the negative binomial regression models showed that second-trimester exposures to PFOA (IRR=1.15, 95%CI: 1.05, 1.26), n-PFOS (IRR=1.08, 95%CI: 1.01, 1.15), 6m-PFOS (IRR=1.13, 95%CI: 1.05, 1.21), and 1m-PFOS (IRR=1.11, 95%CI: 1.03, 1.18) were associated with an increased risk of ADHD-like symptoms in 7-year-old children. Stratified analyses suggested potentially statistically significant associations in girls [e.g., for PFOA, boys vs. girls: 1.09 (0.96, 1.23) vs. 1.25 (1.09, 1.44), P-int=0.31]. The BKMR mixture model indicated that the risk of ADHD-like symptoms trended upward with increasing PFAS mixture concentrations, although this association was statistically significant only among girls (P < 0.05). Conclusion Prenatal PFAS exposure may be associated with an increased risk of ADHD-like symptoms in 7-year-old children, and this adverse association appears to be more prominent in girls.

Objective:To investigate the effect of different programmed death receptor 1 (PD-1)/programmed death receptor ligand 1 (PD-L1) inhibitors combined with chemotherapy in the first-line treatment of extensive-stage small cell lung cancer (ES-SCLC).Methods:All randomized controlled trials (RCT) of PD-1/PD-L1 inhibitors for the first-line treatment of ES-SCLC from the establishment of the database to March 2025 were searched in CNKI database, Wanfang database, VIP Chinese Science and Technology Journal database, China Biomedical Literature Service System, PubMed database, Cochrane Library database and Embase database. Literatures were screened according to inclusion and exclusion criteria, and data were extracted. A network meta-analysis was performed using R 4.3.1 software to analyze the survival and safety of patients with ES-SCLC treated with PD-1/PD-L1 inhibitors combined with chemotherapy and chemotherapy±placebo first-line treatment.Results:A total of 8 RCT involving 3 832 patients with ES-SCLC were included in this analysis. PD-1/PD-L1 inhibitors included pembrolizumab, serplulimab, toripalimab, tislelizumab, adebrelimab, durvalumab, atezolizumab and benmelstobart, and benmelstobart combined with anti-vascular targeted drug anlotinib; the chemotherapy regimen was etoposide combined with platinum-based drugs. Except for durvalumab combined with chemotherapy compared with chemotherapy alone, the control group of the rest was chemotherapy combined with placebo. The included study data were complete and the risk of bias was small, and there was no closed loop in the outcome measures, so the consistency model was uniformly used for analysis. The results of network meta-analysis showed that compared with the control group, PD-1/PD-L1 inhibitors combined with chemotherapy benefited the progression-free survival (PFS) of patients (all P < 0.05), among which benmelstobart and anlotinib combined with chemotherapy had the best improvement in PFS ( HR = 0.32, 95% CI: 0.25-0.40, P < 0.05), and this regimen could benefit the PFS of patients more than other PD-1/PD-L1 inhibitors combined with chemotherapy and serplulimab combined with chemotherapy could benefit the PFS of patients more than pembrolizumab, toripalimab, adebrelimab, durvalumab, and atezolizumab combined with chemotherapy (all P < 0.05). The results of network meta-analysis showed that compared with the control group, all PD-1/PD-L1 inhibitors combined with chemotherapy benefited the overall survival (OS) of patients (all P < 0.05), among which benmelstobart and anlotinib combined with chemotherapy had the best improvement in OS ( HR = 0.61, 95% CI: 0.47-0.79, P < 0.05), but there was no statistically significant difference in OS benefit between each PD-1/PD-L1 inhibitor combined with chemotherapy (all P > 0.05). Ranking of the efficacy of all interventions, the P-scores for PFS and OS were the highest for benmelstobart and anlotinib combined with chemotherapy, which were 0.99 and 0.89, respectively. The results of the network meta-analysis showed that, except for the higher risk of ≥ grade 3 adverse reactions in benmelstobart and anlotinib combined with chemotherapy group compared to the control group ( OR = 2.01, 95% CI: 1.09-3.73, P < 0.05), there was no statistically significant difference in the risk of ≥ grade 3 adverse reactions between the other PD-1/PD-L1 inhibitors combined with chemotherapy group and the control group, or between all PD-1/PD-L1 inhibitors combined with chemotherapy groups (all P > 0.05). Among all PD-1/PD-L1 inhibitors combined with chemotherapy regimens, the tislelizumab combined with chemotherapy regimen had the lowest incidence of ≥grade 3 adverse reactions, with a P-score of 0.70. Conclusions:For the first-line treatment of ES-SCLC patients, the combination of PD-1/PD-L1 inhibitors and chemotherapy regimen has better survival benefits than chemotherapy regimen. Among them, compared with other PD-1/PD-L1 inhibitors, benmelstobart and anlotinib may benefit patients' survival more, but its related adverse reactions should be noted.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To analyze the multimorbidity trends and influencing factors of internet addiction and depressive symptoms among middle school students in Zhejiang Province.Methods:From 2018 to 2023, a multistage stratified random cluster sampling method was used to select middle school students aged 12 to 18 in Zhejiang Province. Internet addiction and depression status were measured by the Internet Addiction Scale and the Center for Epidemiologic Studies Depression Scale. When both symptoms were present, it was defined as multimorbidity.The multivariate logistic regression model was used to analyze the influencing factors of multimorbidity among middle school students, and a trend Chi-square test was used to analyze the changing trends of internet addiction, depression and multimorbidity prevalence. Results:A total of 193 505 students were included in the study. From 2018 to 2023, the prevalence of multimorbidity of internet addiction and depressive symptoms among middle school students ranged from 2.7% to 3.5%. The prevalence of internet addiction ranged from 4.7% to 6.0%, while the prevalence of depressive symptoms ranged from 18.7% to 25.1%. Multivariate logistic regression showed that boarding students ( OR=1.34 , 95% CI: 1.26-1.42), low-frequency ( OR=1.59, 95% CI: 1.46-1.73), and high-frequency sugary drink consumption ( OR=3.91, 95% CI: 3.55-4.31) increased the risk of multimorbidity among middle school students. In contrast, higher frequencies of moderate-to-high-intensity exercise (medium: OR=0.54, 95% CI: 0.50-0.58; high: OR=0.49, 95% CI: 0.44-0.55) and sufficient sleep ( OR=0.52, 95% CI: 0.49-0.56) were protective factors. From 2018 to 2023, there was no significant change in the trend of multimorbidity prevalence among middle school students ( χ2trend=3.82, P=0.051). The prevalence of internet addiction showed an upward trend ( χ2trend=20.54, P<0.001), while depressive symptoms showed a downward trend ( χ2trend=181.41, P<0.001). Conclusion:The prevalence of internet addiction and depression symptoms among middle school students in Zhejiang Province remains stable from 2018 to 2023. The prevalence of internet addiction shows an upward trend, while the prevalence of depression symptoms shows a downward trend. The risk of multimorbidity is related to students′ boarding, consumption of sugary drinks, lack of exercise, and insufficient sleep.
