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.

Objective:To investigate the effects of repeated high acceleration(+Gz)on implant osseointegration in SD rats.Methods:18 SD rats were divided into+Gz and control groups randomly(n=9),and 1 implant was placed in each femur of the rat's lower limb.24 hours postoperatively,the experimental rats were exposed to+Gz of 4 to 9 G with 1 G/s environment 3 times a week,while the con-trol rats were fed normally.3 rats from each of the 2 groups were sacrificed at 2,4 and 8 weeks after implantation.Micro-CT,sequential fluorescence double labeling,and histological examination were perfomed for the analysis of implant osseointegration.Results:The bone volume fraction(BV/TV),trabecular number(Tb.N),mineral apposition rate(MAR),implant-bone contact rate(BIC)and bone area in implant thread(BA)of the+Gz group were significantly lower than those of the control group at 2 weeks(P＜0.05),and so as to MAR,BA at 4 weeks(P＜0.05),while there was no significant difference of the parameters at 8 weeks after implantation.Conclusion:In SD rats early exposure to+Gz environment postoperatively may have a negative effect on initial osseointegration by slowing bone forma-tion.However,it will not lead to poorer bone mass when sustained over a long period.

As a potential vectored vaccine,Newcastle disease virus(NDV)has been subject to various studies for vaccine development,while relatively little research has outlined the immunomodulatory effect of the virus in antigen presentation.To elucidate the key inhibitory factor in regulating the interaction of infected dendritic cells(DCs)and T cells,DCs were pretreated with the NDV vaccine strain LaSota as an inhibitor and stimulated with lipopolysaccharide(LPS)for further detection by enzyme-linked immunosorbent assay(ELISA),flow cytometry,immunoblotting,and quantitative real-time polymerase chain reaction(qRT-PCR).The results revealed that NDV infection resulted in the inhibition of interleukin(IL)-12p40 in DCs through a p38 mitogen-activated protein kinase(MAPK)-dependent manner,thus inhibiting the synthesis of IL-12p70,leading to the reduction in T cell proliferation and the secretion of interferon-γ(IFN-γ),tumor necrosis factor-α(TNF-α),and IL-6 induced by DCs.Consequently,downregulated cytokines accelerated the infection and viral transmission from DCs to T cells.Furthermore,several other strains of NDV also exhibited inhibitory activity.The current study reveals that NDV can modulate the intensity of the innate?adaptive immune cell crosstalk critically toward viral invasion improvement,highlighting a novel mechanism of virus-induced immunosuppression and providing new perspectives on the improvement of NDV-vectored vaccine.

Background: SM-like (LSM) genes a family of RNA-binding proteins, are involved in mRNA regulation and can function as oncogenes by altering mRNA stability. However, their roles in B-cell progression and tumorigenesis remain poorly understood. Methods: We analyzed gene expression profiles and overall survival data of 123 patients with mantle cell lymphoma (MCL). The LSM index was developed to assess its potential as a prognostic marker of MCL survival. Results: Five of the eight LSM genes were identified as potential prognostic markers for survival in MCL, with particular emphasis on the LSM.index. The expression levels of these LSM genes demonstrated their potential utility as classifiers of MCL. The LSM.index-high group exhibited both poorer survival rates and lower RNA levels than did the overall transcript profile. Notably, LSM1 and LSM8 were overexpressed in the LSM.index-high group, with LSM1 showing 2.5-fold increase (p < 0.001) and LSM8 depicting 1.8-fold increase (p < 0.01) than those in the LSM.index-low group.Furthermore, elevated LSM gene expression was associated with increased cell division and RNA splicing pathway activity. Conclusions The LSM.index demonstrates potential as a prognostic marker for survival in patients with MCL. Elevated expression of LSM genes, particularly LSM1 and LSM8, may be linked to poor survival outcomes through their involvement in cell division and RNA splicing pathways. These findings suggest that LSM genes may contribute to the aggressive behavior of MCL and represent potential targets for therapeutic interventions.

Objective:To explore the effect of endometriosis (EM) on reproductive outcomes of young patient with EM after laparoscopic treatment in the first in vitro fertilization-embryo transfer (IVF-ET) cycle.Methods:The clinical data and reproductive outcomes of 394 infertile patients with EM after laparoscopic treatment (EM group) and 3 242 infertile patients caused by gamete transport disorder (control group) in the first IVF-ET cycle were collected in Chongqing Health Center for Women and Children from January 2016 to June 2021. The information included baseline characteristics, oocyte retrieval, embryo development, clinical pregnancy, miscarriage, and live birth. Propensity score matching (PSM) method was used to perform 1∶2 matching between EM group and control group. The impact of EM on reproductive outcomes was analyzed in the retrospective observational study.Results:In the initial data, compared with control group, the number of two pronucleus (2PN) zygotes (9.7±4.8 vs 9.0±4.4), the number of transferable embryos (6.2±3.6 vs 5.5±3.4) and the rate of transferable embryos (64.0% vs 60.8%) on the third day were significantly lower in EM group, and the differences were statistically significant (all P<0.05). After PSM was performed, there were 394 and 787 cases in EM group and control group, respectively. Compared with control group, the number of 2PN zygotes (9.7±4.9 vs 9.0±4.4), the 2PN fertility rate (77.1% vs 75.3%), the number of transferable embryos on the third day (6.2±3.6 vs 5.5±3.4), the transferable embryos rate on the third day (63.8% vs 60.8%) were significantly lower in EM group, and the differences were statically significant (all P<0.05). The study did not find the effect of EM on embryo implantation rate, pregnancy rate, early miscarriage rate, live birth rate and preterm birth rate (all P>0.05). Conclusions:EM might interfere with the development of oocytes and embryos. Obtaining top-quality embryos may be an effective way to improve the prognosis of patients with EM after laparoscopic treatment.

Objective:To determine the relationship between health self-empowerment level and health self-management skill in older adults.Methods:A household survey was conducted from June 2020 to April 2021, among older adults in two communities each in Zhuzhou and Changsha selected by stratified cluster sampling. Data were collected through a general questionnaire, simplified. Elders Health Empowerment Scale, and Rating Scale of Health Self-Management Skill for Adults. A total of 444 questionnaires were distributed, of which 425 were valid. Pearson correlation and hierarchical regression analyses were used to analyze the relationship between health self-empowerment level and health self-management skill.Results:Final sample included 425 elderly people. Health self-empowerment was at medium to high level (30.9±5.6), whereas health self-management was at medium level (146.2±21.7); and the two factors were significantly correlated (Pearson coefficient was 0.724). After controlling for confounding factors (demographic characteristics), health self-empowerment independently accounted for 34.3% of the variation in health self-management ability.Conclusion:Health self-empowerment positively affects health self-management ability among older adults, which suggests the importance of stimulating health self-empowerment awareness in the process of health self-management.
