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.

Objective To analyze the epidemiological characteristics and disease burden of liver cancer in Guangdong Province in 2020, and to provide a scientific foundation for the development of regionalized prevention and control strategies for liver cancer. Methods According to the cancer registry data of Guangdong Province, the incidence, mortality and age-standardized rate by Chinese standard population in 2020 were calculated to analyze the epidemiological characteristics of liver cancer. The disability adjusted life years (DALYs), year of life loss (YLL), year of lived with disability (YLD), and cause-eliminated life expectancy were used to assess the disease burden of liver cancer. Results In 2020, the crude incidence rate and the age-standardized incidence rate of liver cancer in Guangdong Province were 27.79/100 000 and 20.84/100 000,respectively, and the crude mortality rate and the age-standardized mortality rate of liver cancer were 25.49/100,000 and 17.64/100 000, respectively. The total DALY and DALY rate of liver cancer in Guangdong Province were 515 311 person-years and 513.83/100 000, respectively. After eliminating the causes of death from liver cancer, the life expectancy in Guangdong Province increased from 84.60 years to 84.99 years. All indicators consistently demonstrated that the burden of liver cancer was higher in males than that in females, and the burden of liver cancer was higher in rural areas than that in urban areas. Conclusion Liver cancer in Guangdong Province exhibits a high incidence, mortality and disease burden level in 2020. There are obvious differences of gender, age and region in cancer burden. It is necessary to strengthen liver cancer screening and diagnosis and treatment in men, the elderly and those in rural areas to reduce the burden of liver cancer gradually in Guangdong Province.

Objective:
To explore the latent profile characteristics of regulatory emotional self-efficacy and its relationship with non-suicidal self-injurious (NSSI) behavior among junior and senior high school students, so as to provide a basis for effectively reducing NSSI behaviors.
Methods:
From April to October 2023, a total of 1 217 junior and senior high school students were selected from Tongren City, Zunyi City and Qiannan Prefecture of Guizhou Province by stratified cluster random sampling method. The Scale of Regulatory Emotional Self-efficacy and the Adolescent Self-injury Scale were administered. Latent profile analysis (LPA) was employed to explore distinct profiles of regulatory emotional self-efficacy, and the Lanza, Tan, and Bray s method (LTB) was used to analyze the relationship between these profiles and NSSI behavior.
Results:
The prevalence rate of NSSI behavior among junior and senior high school students was 28.6%. Among males, regulatory emotional self-efficacy was categorized into two types: moderate positive expression-low negative management group (59.1%, n =353) and high efficacy group (40.9%, n =244); among females, regulatory emotional self-efficacy was classified into three categories: low efficacy group (18.4%, n =114), high positive expression-low negative management group (56.3%, n =349), and high efficacy group (25.3%, n =157). There were statistically significant differences in total NSSI scores across different potential categories of regulatory emotional self-efficacy within both males and females ( Z/H = -5.75 , 57.58, both P <0.01). The differences in NSSI prevalence rates across the potential categories of regulatory emotional self-efficacy were statistically significant for both males and females ( χ 2=38.00, 69.14, both P <0.01), and among females, the differences in NSSI prevalence rates between the high efficacy group and the low efficacy group ( χ 2=60.01) and between the high efficacy group and the high positive expression-low negative management group ( χ 2=31.34) were also statistically significant (both P < 0.016 7 ). Binary Logistic regression analysis revealed that, compared with the high efficacy group within each gender, the moderate positive expression-low negative management group among males ( OR =2.36), and both the low efficacy group and the high positive expression-low negative management group among females ( OR =6.19, 2.97), were at an increased risk of engaging in NSSI (all P <0.01).
Conclusion
Different latent profiles of regulatory emotional self efficacy among junior and senior high school students are associated with NSSI behavior.

Objective To explore the correlation between kinesiophobia and disease uncertainty, personal mastery, cardiac discomfort symptoms in patients with acute myocardial infarction (AMI) during recovery period. Methods A total of 320 patients with AMI admitted to the hospital were enrolled between January 2020 and January 2024. According to the results of Tampa Scale for Kinesiophobia Heart (TSK-H), they were divided into AMI kinesiophobia group (n=166) and simple AMI group (n=154). The disease uncertainty was evaluated by Mishel Uncertainty in Illness Scale for Adults (MUIS-A), personal mastery was evaluated by Personal Mastery Scale (PMS), and cardiac discomfort symptoms were evaluated by cardiac discomfort symptom scale. The correlation between kinesiophobia and disease uncertainty, personal mastery, cardiac discomfort symptoms in AMI patients was analyzed by Pearson correlation analysis. Results The scores of MUIS-A and cardiac discomfort symptoms in AMI kinesiophobia group were higher than those in simple AMI group (P<0.05), and PMS scores were lower than those in simple AMI group (P<0.05). The score of kinesiophobia was significantly positively correlated with scores of disease uncertainty and cardiac discomfort symptoms (r=0.628, 0.689, P<0.05), while significantly negatively correlated with the score of personal mastery (r=-0.526, P<0.05). Conclusion Kinesiophobia is related to disease uncertainty, personal mastery and cardiac discomfort symptoms in AMI patients during recovery period. Clinical medical staffs should focus on patients with the above characteristics. The targeted intervention measures can improve kinesiophobia and promote recovery of patients.

ObjectiveTo investigate the current professional competency among full-time and part-time personnel of the nosocomial infection control administration in Shanghai, so as to provide a scientific basis for future training programmes. MethodsIn December 2024, a questionnaire survey was conducted by the Shanghai Nosocomial Infection Quality Control Center among full-time and part-time personnel of the nosocomial infection control administration across medical institutions at various levels and types in Shanghai using convenience sampling method. The questionnaire consisted of two parts: demographic information and professional competency assessment. The professional competency scale comprised four dimensions: fundamental cognition, basic skills, professional expertise, and personal qualities, totaling 35 items. ResultsA total of 1 179 questionnaires were distributed, with 1 144 valid responses collected, yielding an effective response rate of 97.03%. Statistically significant differences were observed among full-time and part-time personnel of the nosocomial infection control administration in terms of age (t=5.32, P=0.021), professional background (χ2=9.90, P=0.019), educational qualifications (χ2=19.10, P<0.001), professional titles (χ2=12.60, P=0.002), and the levels of medical institutions (χ2=111.08, P<0.001). The scores of full-time personnel of the nosocomial infection control administration in fundamental cognition [92 (82, 99) points] and basic skills [88 (78, 96) points] were significantly higher than those of part-time personnel(Z=-2.21, P=0.027;Z=-2.74, P=0.006). Statistically significant differences were found in fundamental cognition scores between full-time and part-time personnel of the nosocomial infection control administration regarding occupational safety protection, definition of healthcare-associated infection outbreaks, types of drug-resistant bacteria and their prevention and control strategies, and transmission routes of different infectious diseases (all P<0.05). Statistically significant differences were also observed in basic skills scores including proficient use of monitoring platforms, formulation and revision of standard operating procedures (SOPs), independent completion of targeted surveillance, guidance on basic infection control skills, guidance for key departments, and follow-up of personnel with occupational exposure (all P<0.05). However, no statistically significant differences were found in scores of professional knowledge and personal qualities (P>0.05). ConclusionThere are certain differences in professional competency between full-time and part-time personnel of the nosocomial infection control administration in Shanghai in terms of fundamental cognition and basic skills. Part-time personnel can effectively improve their professional competency through systematic training on basic infection control knowledge and practical skills, thereby comprehensively enhancing the overall quality of the nosocomial infection administration team.

The blood-brain barrier (BBB) is a physical and biochemical barrier that precisely regulates brain homeostasis and plays a central role in controlling the transport of endogenous and exogenous drugs and related metabolites across the blood-brain interface. These functions of the BBB are mediated by its major components, including brain microvascular endothelial cells (BMECs), tight junction protein complexes, and influx and efflux transporter proteins. One of the pathological features of ischemic stroke (IS) is BBB disruption, which plays an important role in the development of post-stroke brain injury and subsequent neurological dysfunction. Therefore, given the increasing incidence of IS, there is an urgent need to develop new therapeutic strategies to prevent BBB dysfunction and thereby protect injured brain tissue after IS. This study describes the pathological mechanisms by which BMEC injury after IS leads to BBB dysfunction and elucidates the association between BMECs and IS, including the regulation of apoptosis, autophagy, inflammatory responses, oxidative stress, neurotoxic effects, and cerebral edema. In addition, this article summarizes Chinese herbal medicines that may prevent and treat IS by targeting BMECs. These include monomeric compounds and single herbs such as flavonoids, glycosides, phenols, phthalides, terpenoids, and Styrax. Traditional Chinese medicine (TCM) compound formulas and preparations include oral formulations such as Buyang Huanwu decoction, Sailuotong, Naoxintong capsules, Dandeng Tongnao capsules, and Shexiang Tongxin dropping pills, as well as injectable preparations such as Tongluo Jiunao injection, Xingnaojing injection, Danshen polyphenolic acid for injection, Yiqi Fumai injection, and Shuxuetong injection. This study aims to explore the protective effects of TCM against IS through targeted regulation of BMEC function, providing new insights into the mechanisms of IS and endovascular therapeutic strategies.

Object To study the efficacy and potential mechanism of Tongbianling capsule in constipation. Methods The effects of Tongbianling capsule on intestinal motility in normal mice and carbon powder propulsion rate in small intestine of constipation model mice after were observed administration. The potential targets and key pathways of Tongbianling capsule in treating constipation were identified through network pharmacology. To verify the mechanism, the expression of p-PI3K/PI3K, p-AKT/AKT and CASP3 proteins in mouse colon tissue was detected by the western blot. Results The time for mice to excrete the first black stool was shortened and the number of fecal particles was increased in Tongbianling capsule administration group, and the carbon powder propulsion rate of mice in each Tongbianling capsule administration group was increased. The results of network pharmacology showed that treatment of constipation by Tongbianling capsule may be related to signaling pathways such as PI3K-Akt signaling pathway and 5-HT. The protein expression of p-PI3K/PI3K, p-AKT/AKT, and CASP3 in mouse colon tissue could be significantly downregulated in administration group. Conclusion Tongbianling capsule could effectively promote intestinal peristalsis in mice, increase the frequency of defecation, and effectively treat constipation. The mechanism of its action may be related to the direct or indirect regulation of intestinal motility by the PI3K-Akt signaling pathway.
