ObjectiveTo explore the effects of Renshentang on atherosclerosis （AS） in mice based on the role of transient receptor potential vanilloid1 （TRPV1） in regulating cholesterol metabolism in foam cells. MethodsNine SPF-grade 8-week-old C57BL/6J mice were set as a normal group， and 60 ApoE^-/- mice were randomized into model， positive drug （simvastatin， 0.02 g·kg^-1·d^-1）， and low-， medium-， and high-dose （1.77， 3.54， 7.08 g·kg^-1·d^-1， respectively） Renshentang groups （n=12） according to body weight. The normal group was fed with a normal diet， and the other groups were fed with a high-fat diet and given corresponding drugs by oral gavage for the modeling of AS. The mice were administrated with corresponding drugs once a day for 12 weeks. After the last administration and fasting for 12 h， the aorta was collected. Plaque conditions， pathological changes， levels of total cholesterol （TC）， triglcerides （TG）， low-density lipoprotein-cholesterol （LDL-C）， and high-density lipoprotein-cholesterol （HDL-C）， and the expression of TRPV1， liver X receptor （LXR）， inducible degrader of the low-density lipoprotein receptor （IDOL）， and low-density lipoprotein receptor （LDLR） in the aortic tissue were observed and detected by gross oil red O staining， HE staining， Western blot， immunohistochemistry， and real-time PCR. ResultsCompared with the normal group， the model group presented obvious plaque deposition in the aorta， raised levels of TC， TG， and LDL-C in the serum （P<0.01）， up-regulated expression level of LDLR in the aorta （P<0.01）， lowered level of HDL-C in the serum， and down-regulated expression levels of TRPV1， LXR， and IDOL in the aorta （P<0.05， P<0.01）. Compared with the model group， the positive drug and Renshentang at different doses alleviated AS， elevated the levels of HDL-C， TRPV1， LXR， and IDOL （P<0.05， P<0.01）， while lowering the levels of TC， TG， LDL-C， and LDLR （P<0.05， P<0.01）. ConclusionRenshentang has a lipid-lowering effect on AS mice. It can effectively reduce lipid deposition， lipid levels， and plaque area of AS mice by activating TRPV1 expression and regulating the LXR/IDOL/LDLR pathway.

OBJECTIVE: To observe the clinical efficacy of acupoint thread-embedding therapy of regulating governor vessel, dispersing lung, and suppressing reflux for gastroesophageal reflux cough (GERC). METHODS: A total of 120 GERC patients were randomly assigned to an observation group (60 cases, 1 case dropped out) and a control group (60 cases, 1 case was eliminated). The observation group received acupoint thread-embedding treatment at positive response points of governor vessel. If no such points were detected, the following acupoints were used: Dazhui (GV14), Fenghu (Extra), Shendao (GV11), Lingtai (GV10), and Zhiyang (GV9). Treatment was administered once every two weeks. The control group received oral rabeprazole enteric capsules at 20 mg twice daily. All the treatment was given for 6 weeks. Clinical outcomes were assessed using cough symptom score, reflux disease questionnaire (RDQ) score, and Leicester cough questionnaire (LCQ) score before and after treatment in the two groups. Clinical efficacy was also compared between the two groups. RESULTS: After treatment, both groups showed decreased cough symptom scores and the each item scores and total scores of RDQ (P<0.001), and increased LCQ scores (P<0.001) compare with those before treatment. The observation group exhibited lower cough symptom score and chest pain, reflux and total score of RDQ, and higher LCQ score compared to those in the control group (P<0.05). The total effective rate in the observation group was 94.9% (56/59), which was higher than 84.7% (50/59) in the control group (P<0.05). CONCLUSION Acupoint thread-embedding therapy of regulating governor vessel, dispersing lung, and suppressing reflux could effectively alleviate cough and reflux symptoms in patients with GERC and improve their quality of life.

China is a high-incidence region for gastric cancer globally. The disease is characterized by a high morbidity rate, low early diagnostic rate, and poor long-term outcomes, imposing a significant burden on both patients and society. Therefore, exploring the pathogenesis of gastric cancer, developing novel therapeutic strategies, and identifying new drug targets is of great importance. Telomerase expression is broadly associated with cancer cell targeting, and its up-regulation is one of the key factors driving the initiation and progression of gastric cancer. Additionally, telomerase is intricately involved in the regulation of autophagy and autophagy-associated cell death. While autophagy can induce chemoresistance, excessive autophagy may lead to cell death, which also constitutes one of the mechanisms of chemotherapy. Telomerase not only directly contributes to gastric cancer pathogenesis but also indirectly influences its development and treatment by modulating autophagy and autophagic cell death. Therefore, telomerase holds promise as a novel therapeutic target in gastric cancer.

Objective To investigate the expression and clinical value of γδT cells and related inflammatory factors in endometrial polyps(EP).Methods Subjects were patients with infertility due to EP(EP group,n=57)and infertility due to non-uterine factors(Control group,n=44).EP tissues and normal endometrial tissues were taken,respectively.The general characteristics of the two groups were evaluated by independent samples T-test or Wilcoxon rank sum test.The expressions of CD3 and TCRγδ in proliferative endometrium and endometrial polyps were observed by immunofluorescence,and the expressions of IL-17 and IFN-γ in tissue homogenate were detected by ELISA.Uni-variable linear regression was used to analyze the correlation between the number of γδT cells and the expression level of IL-17 and IFN-γ.Results Both the number of γδT cells and he levels of IL-17 and IFN-γsignificantly increased in endometrial polyp tissues,and the relationship between is linear(all P＜0.05).Conclu-sion γδT cells are associated with EP among infertile women,which may lead to embryo implantation failure by affecting the expression of inflammatory factors and regulating the imbalance of cell subsets.

Influenza imposes a significant disease burden on society and individuals annually, and influenza vaccination is considered a significant public health measure to prevent influenza and reduce influenza-related severe disease and death. The low influenza vaccination rate in China is partly due to certain factors affecting the willingness and behavior of individuals to receive them. Scientific research and targeted interventions on these factors can effectively improve the vaccination situation. Commonly used individual-level theoretical models for influenza vaccination behavior include the health belief model, protection motivation theory, and theory of planned behavior. This study reviews theoretical models commonly employed in researching influenza vaccination willingness and behavior. An overview of these practical applications and challenges models is presented to provide references for relevant research and intervention programs in China.

OBJECTIVE To explore the mechanism of Baihe Dihuang decoction in the treatment of Alzheimer's disease(AD) based on network pharmacology, molecular docking and animal experiment. METHODS TCMSP were used to predict the active components and targets of Baihe Dihuang decoction and disease-related targets were collected from GeneCards, OMIM and DRUGBANK databases, respectively. Target protein interactions were analyzed with STRING database and biological function and pathway were analyzed with Metascape database. Lastly relevant results were analyzed with Cytoscape 3.8.0. AutoDock vina software was used for molecular docking to analyze the binding energy of the active components and key targets of Baihe Dihuang decoction. PyMOL software were used to visualize the optimal docking results. ICR male mice were randomly divided into control group, model group, Rolipram group, low, medium and high dose group of Baihe Dihuang decoction. After 14 days of administration, the neurobehavioral scores of mice in each group were collected, and the expression of related proteins in brain tissue was detected, ELISA and Western blotting were used to detect the expression of the key protein cAMP, PKA, p-CREB and BDNF. At last, the adverse reaction of Baihe Dihuang decoction was observed by vomiting experiment. RESULTS A total of 13 active components and 39 key targets were collected from network pharmacology. The docking results showed that the first 10 core targets all performed well and their effects were closely related to PRKACA. Compared with the control group, the model group mice's recognition rate of new objects and the spontaneous alternation reaction rate were significantly reduced, the escape latency was significantly prolonged, and the target quadrant stay time, the number of crossing platforms were significantly reduced; cAMP, PKA, p-CREB and BDNF in the hippocampus of mice was significantly decreased. Baihe Dihuang decoction could reverse the behavior of AD mice and the expression of cAMP, PKA, p-CREB and BDNF. In the vomiting experiment, the anesthesia recovery time of the Rolipram group was significantly prolonged, while that of the Baihe Dihuang decoction group was not significantly affected. CONCLUSION The mechanism of Baihe Dihuang decoction in the treatment of AD may be related to its influence on cAMP-PKA and regulation of cAMP-PKA-CREB-BDNF signal pathway, and the adverse reactions are milder than those of clopramide.

Objective:To introduce the experience of reconstructing the pelvic floor with a pedicled large omental flap combined with a basement membrane biological mesh in combined pelvic organ resection for locally advanced or locally recurrent rectal cancer combined with sacrococcygeal resection, and to discuss the feasibility, safety, and near-term therapeutic efficacy of this technique.Methods:For patients with sacrococcygeal resection of combined pelvic organs, a basement membrane mesh was used to rebuild the pelvic floor with a pedicled greater omentum flap to isolate the abdominopelvic cavity. The main operation was to pull the greater omentum, which preserved the double vascular arches, to the pelvic floor to cover the pelvic floor, and then the mesh was used to cover the posterior peritoneal defect and pelvic inlet with absorbable sutures of 2-0 or thicker.Results:In this study, a retrospective cohort study was used to collect clinical data through the China Rectal Cancer Combined Pelvic Organs Resections Case Database. Twenty patients with locally advanced or locally recurrent rectal cancer without extra-pelvic metastasis or only oligometastases underwent combined pelvic organ and sacrococcygeal resection in the Department of Anal and Intestinal Surgery of the Second Affiliated Hospital of the Naval Military Medical University during the period of July 1, 2022, to June 30, 2023, and 10 patients underwent simple basement membrane resection with a simple basement membrane. Among them, the pelvic floor were reconstructed by basement membrane mesh alone in 10 cases (mesh only group), and 10 cases were reconstructed the pelvic floor by pedicled large omental flap combined with basement membrane mesh (omental flap-combined mesh group). The recent outcomes of the two groups of patients were studied comparatively. Comparison of baseline data and intraoperative conditions between the two groups showed no statistically significant differences (all P>0.05); the drain removal time in the omental flap-combined mesh group was 26.7 (19-42) days, which was shorter than that in the mesh only group, which was 40.4 (24-56) days ( U=4.125, P=0.001); The empty pelvis healing time in the omental flap-combined mesh group was 29.4 (23~43) days, which was shorter than that of 42.2 (27~58) days in the mesh-only group ( U=4.043, P=0.001); the differences were all statistically significant. The postoperative complication rate of grade ≥III in the omental flap-combined mesh group was 1/10, which was lower than that of 6/10 in the mesh-only group; the difference was not statistically significant when comparing the two groups ( P = 0.057). Follow-up ended on 09/30/2023, with a median follow-up of 9.5 (3-15) months in 20 patients, and all 20 cases survived during the follow-up period, with no tumor recurrence at the surgical site. Conclusion:In locally advanced or locally recurrent rectal cancer undergoing combined pelvic organ resection with sacrococcygeal, compared with reconstruction of the pelvic floor by basement membrane mesh alone, reconstruction of the pelvic floor and isolation of the abdominopelvic cavity by a pedicled greater omentum flap combined with a basement membrane mesh is safe and feasible.

Objective To investigate the expression of PCI Domain Containing 2(PCID2)in gastric cancer,its effect on gastric cancer cell cycle and proliferation and the possible molecular mechanisms.Methods We examined PCID2 expression levels in gastric cancer and adjacent tissues from 100 patients undergoing radical gastrectomy in our hospital between January,2012 and December,2016,and analyzed the correlation of PCID2 expression level with cancer progression and postoperative 5-year survival rate of the patients.GO enrichment analysis was performed to identify the possible pathways that mediated the effect of PCID2 in gastric cancer progression.The effects of lentivirus-mediated PCID2 knockdown and overexpression on cell proliferation and cell cycle were analyzed in gastric cancer MGC-803 cells and in nude mice.Results PCID2 was highly expressed in gastric cancer tissues and positively correlated with peripheral blood levels of CA19-9 and CEA(P<0.01).In gastric cancer patients,a high PCID2 expression was associated with a significantly lowered postoperative 5-year survival rate(P<0.001)as an independent risk factor for postoperative survival(HR:2.987,95%CI:1.616-5.519).The sensitivity,specificity,and area under the curve of PCID2 for predicting postoperative 5-year survival were 76.74%,75.44%,and 0.755(P<0.001),respectively.GO enrichment analysis suggested that PCID2 was associated with gastric cancer cell cycle progression.PCID2 overexpression in MGC-803 cells significantly promoted cell proliferation,G1/S phase transition,expressions of cyclin D1 and CDK6,and the growth of transplanted xenograft in nude mice(P<0.05).The expressions of p27 and p16 were significantly lowered in gastric cancer tissues,and their expression levels were negatively regulated by PCID2 expression in MGC-803 cells(P<0.05).Conclusion PCID2 is highly expressed in gastric cancer tissues in close correlation with poor prognosis of the patients.High PCID2 expression promotes gastric cancer proliferation and cell cycle progression by inhibiting the expression of p27 and p16.

Objective To investigate the expression level of Kruppel-like transcription factor family member KLF11 in intestinal mucosal tissues of Crohn's disease (CD) and its regulatory effect on intestinal inflammation in CD-like colitis. Methods We examined KLF11 expression levels in diseased and normal colon mucosal tissues from 12 CD patients and 12 patients with colorectal cancer using immunofluorescence staining. KLF11 expression was also detected in the colon mucosal tissues of a mouse model of 2,4,6-trinitrobenesulfonic acid (TNBS)-induced colitis. A recombinant adenoviral vector was used to upregulate KLF11 expression in the mouse models and the changes in intestinal inflammation was observed. A Caco-2 cell model with stable KLF11 overexpression was constructed by lentiviral infection. The effect of KLF11 overexpression on expressions of JAK2/STAT3 signaling pathway proteins was investigated using immunoblotting in both the mouse and cell models. The mouse models were treated with coumermycin A1, a JAK2/STAT3 signaling pathway agonist, and the changes in intestinal inflammatory responses were observed. Results The expression level of KLF11 was significantly lowered in both the clinical specimens of diseased colon mucosal tissues and the colon tissues of mice with TNBS-induced colitis (P<0.05). Adenovirus-mediated upregulation of KLF11 significantly improved intestinal inflammation and reduced the expression levels of inflammatory factors in the intestinal mucosa of the colitis mouse models (P<0.05). Overexpression of KLF11 significantly inhibited the expression levels of p-JAK2 and p-STAT3 in intestinal mucosal tissues of the mouse models and in Caco-2 cells (P<0.05). Treatment with coumermycin A1 obviously inhibited the effect of KLF11 upregulation for improving colitis and significantly increased the expression levels of inflammatory factors in the intestinal mucosa of the mouse models (P<0.05). Conclusion KLF11 is downregulated in the intestinal mucosa in CD, and upregulation of KLF11 can improve intestinal inflammation and reduce the production of inflammatory factors probably by inhibiting the JAK2/STAT3 signaling pathway.
