ABSTRACT
ObjectiveTo observe the clinical efficacy of modified Zuojinwan granules in treating reflux esophagitis （RE） and functional dyspepsia （FD） with the same syndrome with disharmony between liver and stomach）. MethodA randomized double-blind placebo-controlled clinical trial was conducted to enroll 144 patients with disharmony between liver and stomach， including 72 patients with RE and 72 patients with FD. These patients were then randomly divided into observation and control groups， with 36 patients in each group. The observation group was given modified Zuojinwan granules orally， and the control group was given placebo granules orally. They both were treated with two packs each time， twice a day， for four weeks. The traditional Chinese medicine （TCM） syndrome scores， cerebrointestinal peptides ［calcitonin gene-associated titanium （CGRP）， vasoactive intestinal peptide （VIP）， 5-hydroxytryptamine （5-HT）， and substance P （SP）］， inflammatory factors ［tumor necrosis factor-α （TNF-α） and interleukin-6 （IL-6）］， common gastrointestinal related hormones ［gastrin （GAS） and motilin （MTL）］， and other indicators in the two groups were compared before and after treatment， and the curative effect of TCM syndromes and the occurrence of adverse reactions were determined. At the same time， the changes in the above indicators and the curative effect of TCM syndromes in the two groups of patients with the same disease were analyzed. ResultAfter treatment， CGRP， VIP， 5-HT， SP， TNF-α， IL-6， GAS， MTL， and TCM syndrome scores in the observation group and control group were significantly improved （P<0.05）. After treatment， the improvement of CGRP， VIP， 5-HT， SP， TNF-α， IL-6， GAS， MTL， and TCM syndrome scores in the observation group was better than that in the control group （P<0.05）. After treatment， CGRP， VIP， 5-HT， SP， TNF-α， IL-6， GAS， MTL， and TCM syndrome scores in both groups of RE patients and FD patients were significantly improved （P<0.05）. After treatment， the improvement of CGRP， VIP， 5-HT， SP， TNF-α， IL-6， GAS， MTL， and TCM syndrome scores in RE patients and FD patients in the observation group were better than that in the control group （P<0.05）. In the observation group and the control group， the incidence of nausea， vomiting， fatigue， dry mouth， and other adverse reactions was lower， and there was no statistical significance. ConclusionModified Zuojinwan granules can effectively improve the TCM syndromes of disharmony between liver and stomach of RE and FD， brain and intestinal peptide， gastrointestinal hormone， and inflammatory factors and provide evidence for the clinical application of TCM theory of "treating different diseases with the same method".
ABSTRACT
Objective:To discuss the regulatory effect of berberine(BBR)on fatty acids in the human glioma T98G cells and its effect on the cell proliferation,migration,and invasion,and to clarify its potential mechanism.Methods:The T98G cells at logarithmic growth phase were divided into control group and different concentrations(25,50,and 100 mg·L-1)of BBR groups.Cell wound healing assay was used to detect the migration rates of the cells in various groups;Transwell chamber assay was used to detect the invasion rates of the cells in various groups.The T98G cells at logarithmic growth phase were divided into control group and 100 mg·L-1 BBR group,and Mass spectrometry was used to detect the fatty acid contents in the cells in two groups.The T98G cells at logarithmic growth phase were divided into control group and different concentrations(50,100,and 150 mg·L-1)of BBR groups;Western blotting method was used to detect the expression levels of phosphatidylinositol 3-kinase(PI3K),phosphorylated PI3K(p-PI3K),protein kinase B(AKT),phosphorylated AKT(p-AKT),sterol regulatory element-binding protein 1(SREBP-1),and fatty acid synthase(FASN)in the cells in various groups.The expression of FASN was suppressed by gene silencing technology,and the T98G cells at logarithmic growth phase were divided into control group,shFASN1 group,and shFASN2 group.Western blotting method was used to detect the expression levels of FASN protein in the cells in various groups;clone formation assay was used to detect the clone formation of the cells in various groups;cell wound healing assay was used to detect the migration rates of the cells in various groups.Results:Compared with control group,the migration rates and invasion rates of the cells in different concentrations of BBR groups were decreased in a concentration-dependent manner(P<0.01),and the fatty acid content in the cells in 100 mg·L-1 BBR group was significantly decreased(P<0.01).Compared with control group,the expression levels of p-PI3K,p-AKT,SREBP-1,and FASN proteins in the cells in 150 mg·L-1 BBR group were significantly decreased(P<0.05 or P<0.01),and the expression level of SREBP-1 protein in the cells in 100 and 150 mg·L-1 BBR groups were significantly decreased(P<0.01).After suppression of FASN expression,compared with control group,the expression levels of FASN protein in the cells in shFASN1 and shFASN2 groups were significantly decreased(P<0.01),and the expression level of FASN protein in the cells in shFASN2 group was lower than that in shFASN1 group(P<0.05);compared with control group,the numbers of clone formation and migration rates of the cells in shFASN1 and shFASN2 groups were significantly decreased(P<0.01),and the migration rate of the cells in shFASN2 group was significantly lower than that in shFASN1 group(P<0.05).Conclusion:BBR interferes with fatty acid synthesis in the glioma T98G cells by reducing the expression of the PI3K/AKT/SREBP-1/FASN pathway related proteins,and decrease their migration and invasion capabilities.

ABSTRACT
Objective To compare the efficacy of TightRope loop plate and Endobutton plate in the treatment of acromioclavicular joint dislocation.Methods A retrospective analysis was conducted on 94 patients with acromioclavicular joint dislocation who were treated at this center from March 2021 to February 2023.They were divided into two groups based on different admission date.The Group E(n =47)received Endobutton plate treatment between March 2021 and February 2022,while the Group T(n =47)received TightRope loop plate treatment between March 2022 and February 2023.At the last follow-up,the perioperative indicators,Visual Analogue Scale(VAS),Constant-Murley shoulder joint function scores,and surgical complications were compared between the two groups.Results The surgical time,intraoperative bleeding,incision length,and VAS scores at 7 days after surgery in the Group T were shorter or lower than those in the Group E(P<0.05).There were no statistical differences in the incidence of perioperative nerve injury,internal fixation displacement,clavicle fracture,vascular injury,and infection between the two groups(P>0.05).The subjective and objective scores of Constant-Murley shoulder joint function in both groups at9 months after surgery showed significant improvement compared to preoperative scores(all P =0.000).There was no significant difference in the subjective and objective scores of Constant-Murley shoulder joint function between the two groups at 9 months after surgery(P>0.05).Conclusions The treatment of acromioclavicular joint dislocation with TightRope loop plate ot or Endobutton plate has a significant effect and can effectively improve shoulder joint function.Compared with Endobutton plate,use of TightRope loop plate has minor surgical trauma,less bleeding,and significantly reduced postoperative pain,being more conducive to early functional exercise for patients.
ABSTRACT
COVID-19 associated Guillain-Barré syndrome (GBS) caused by peripheral nerve damage after SARS-CoV-2 infection is one of the most common COVID-19 related nervous system inflammatory diseases, with high incidence of respiratory failure and mortality. Positive SARS-CoV-2 RNA in cerebrospinal fluid of COVID-19 associated GBS patients has been rarely reported. This paper reports 4 patients with COVID-19 associated GBS in China who developed neurological symptoms 4-15 days after fever and were confirmed SARS-CoV-2 infection. All patients presented with progressive weakness of both lower limbs, 3 patients with autonomic dysfunction such as defecation and urination disorders, and 1 patient with polycranial neuritis and Miller-Fisher syndrome such as bilateral facial palsy, dysphagia, diplopia and ataxia. Nerve conduction velocity and F wave were abnormal in 3 patients, and motor conduction pathway was abnormal in 1 patient. Anti-ganglioside antibodies were tested in 3 patients, and GD1a-IgG was positive in 1 patient. All 4 patients underwent metagenomic next-generation sequencing examination in blood and cerebrospinal fluid. SARS-CoV-2 RNA was positive in blood and cerebrospinal fluid of 3 patients, and SARS-CoV-2 RNA was positive in cerebrospinal fluid of 1 patient.
ABSTRACT
Traumatic fractures and stress fractures are common orthopedic diseases, and there is great potential in researching bone turnover, repair, and promotion of fracture healing. Basic medical experiments often use animal models of long bone fractures in limbs to study the mechanisms of various interventions on fracture healing. Fracture healing is a complex process influenced by multiple factors and involves multiple molecules and pathways. Therefore, to explore the mechanisms more deeply, accelerate the translation of results, and improve the clinical efficacy, it is particularly important to choose the appropriate animal fracture modeling methods in experimental research. Based on this, this paper conducts a literature review of animal species and modeling methods commonly used for long bone fracture models in experimental research. It summarizes five methods: bone defect method, physical impact method, mechanical bending method, open osteotomy method, and drilling method. A side-by-side comparison of their advantages, disadvantages, and scope of application is made, aiming to provide suitable fracture models for studying the mechanisms of fracture healing interventions.
ABSTRACT
In order to build a global community of health for all, it is necessary to deeply understand the influencing factors of cross-cultural communication between medical professionals and patients. Factors such as different health beliefs, cultural values and communication mediators influence cross-cultural communication between medical professionals and patients, and then affect the medical satisfaction and treatment compliance. Medical education should adopt the learning concept of constructivism, advocate maintaining a humble cultural attitude, incorporate more patient perspectives and adopt cross-cultural teaching mode to improve the cross-cultural communication competence of medical students and medical staff, so as to establish a relationship based on communication and understanding.
