Objective To study the therapeutic effects of Yigan Fupi decoction(YGFP)on irritable bowel syndrome(IBS)and its mechanism of action in repairing the intestinal barrier and reducing IBS sensitivity through the PKA/PKC-CREB pathway.Methods Baby rats separated from their mother were randomly divided into a model control(M)and a YGFP group,while baby rats without maternal separation were used as a normal control(N)group.The YGFP group was given YGFP for 4 weeks.Abdominal withdrawal reflux was used to evaluate intestinal sensitivity.Liquid chromatography tandem mass spectrometry and ELISA were used to detect bile acid metabolite concentrations and serum levels of interleukin(IL)-6 and CXCL1,respectively.HE staining was used to observe pathological changes in the colon,and Western Blot and immunohistochemistry were used to analyze the relative protein expression levels of PKA,PKC,CREB,5HT2AR,5-HT7R,ZO-1,and Claudin 1.Results Compared with the normal control group,the M group showed a significantly decreased visceral pain threshold,significantly increased levels of total bile acid metabolites,IL-6,and CXCL1,significantly increased relative expression of PKA,PKC,CREB,5HT2AR,and 5-HT7R,and significantly decreased relative expression of ZO-1 and Claudin 1.Compared with the M group,the YGFP group showed a significantly increased visceral pain threshold,significantly reduced levels of total bile acid metabolites,IL-6,and CXCL1,significantly reduced relative expression of PKA,PKC,CREB,5HT2AR,and 5-HT7R,and increased relative expression of ZO-1 and Claudin 1.Conclusions YGFP effectively improved IBS through a mechanism that may involve repair of the intestinal barrier and reduced sensitivity through the PKA/PKC-CREB pathway.

Objective:To explore the feasibility, safety, and effectiveness of a novel suture instrument for closure of full thickness defects of the gastric wall under gastroscopy.Methods:Ten pigs were used as experimental animals. Perforation model (30 mm in long diameter) was created in the stomach of each pig. The perforations were then closed by the novel suture instrument under gastroscopy. The completion time and efficacy of each perforation repair were recorded. The pigs were euthanized 14 days after the procedure. The healing condition was observed under gastroscopy. A postmortem examination was performed to observe the abdominal infection and healing condition of perforation. Ascites sample was taken for bacterial culture.The stomach biopsy were taken for histopathologic examination.Results:All gastric perforation models in the 10 pigs were established successfully. Endoscopic closure for the stomach perforation was technically successful in all 10 pigs. The procedure time was 34.10±10.32 minutes. All animals survived. Gastroscopy and necropsy showed that the perforation healed well with local adhesion. One pig developed abdominal infection. Ascites culture were negative in 9 cases, 1 bacterial infection was caused by Arcanobacterium pyogenes and Escherichiacoli. The pathology results showed that the muscular layer of the gastric wall defect in the entire group was well repaired. Conclusion:The novel suture instrument is safe and effective in repairing full-thickness gastric wall defects under ordinary single clamp gastroscopy, providing an experimental basis for further clinical research.

Objective To investigate the effect of type 2 dengue virus(DENV-2)infection on autophagy in human umbilical vein endothelial cells(HUVECs)and the mechanism mediating the inhibitory effect of baicalin against DENV-2 infection.Methods Cultured HUVECs with DENV-2 infection were treated with different concentrations of baicalin,and the changes in autophagy of the cells were detected using transmission electron microscopy.Lyso Tracker Red staining was used to examine pH changes in the lysosomes of the cells,and the expressions of ATG5,beclin-1,LC3,P62,STX17,SNAP29,VAMP8,and PI3K/AKT signaling pathway-related proteins were detected by Western blotting.DENV-2 replication in the cells were evaluated using RT-qPCR.The differentially expressed proteins in DENV-2-infected HUVECs were identified by proteomics screening.Results Treatment with baicalin did not significantly affect the viability of cultured HUVECs.Proteomic studies suggested that the PI3K-AKT pathway played an important role in mediating cell injury induced by DENV-2 infection.The results of RT-qPCR demonstrated that baicalin dose-dependently inhibited DENV-2 replication in HUVECs and produced the strongest inhibitory effect at the concentration of 50 μg/mL.Transmission electron microscopy,Lyso Tracker Red staining,RT-qPCR,and Western blotting all showed significant inhibitory effect of baicalin on DENV-2-induced autophagy in HUVECs.DENV-2 infection of HUVECs caused increased cellular expressions of LC3 and P62 proteins,which were significantly lowered by treatment with LY294002(a PI3K inhibitor).Conclusion Baicalin inhibits DENV-2 replication in HUVECs and suppresses DENV-2-induced cell autophagy by inhibiting the PI3K/AKT signaling pathway.

Objective To investigate the current situation and existing problems regarding the diagnosis and treatment integrating traditional Chinese and western medicine in the emergency departments of various general hospitals in China to provide a reference for the development of integrated traditional Chinese and western medicine emergency medicine. Methods From November 18,2022 to February 28,2023,an online questionnaire survey was conducted among 291 hospitals in 21 provinces/municipalities directly under the Central Government across the country,which was based on the members of the Emergency Medicine Professional Committee of the Chinese Association of the Integration of Traditional Chinese and Western Medicine. The questionnaire covered 5 aspects:basic information of hospitals and emergency departments,personnel allocation,medical quality management,equipment allocation,and traditional Chinese medicine techniques and skills (including the application of traditional Chinese medicine and non-drug treatment of traditional Chinese medicine). A comparative study was carried out between the "hospitals of traditional Chinese medicine and integrated traditional Chinese and western medicine" and "western medicine hospitals" on the current situation of integrated traditional Chinese and western medicine diagnosis and treatment in the emergency department. Results A total of 291 valid questionnaires were collected,covering 291 hospitals in 21 provinces and municipalities directly under the Central Government across the country. Among them,142 were hospitals of traditional Chinese medicine and integrated traditional Chinese and western medicine,and 149 were western medicine hospitals. The number of doctors in the emergency departments of hospitals of traditional Chinese medicine and integrated traditional Chinese and western medicine were significantly less than that of western medicine hospitals[individuals:11.00 (7.00,18.75) vs. 20.00 (13.00,31.00),P<0.01]. Specifically,the numbers of traditional Chinese medicine doctors,integrated traditional Chinese and western medicine doctors,and "western medicine doctors learning traditional Chinese medicine" in these hospitals were significantly higher than those in western medicine hospitals[individuals:4.00 (2.00,9.00) vs. 0.00 (0.00,0.00),1.00 (0.00,4.00) vs. 0.00 (0.00,0.00),2.00 (0.00,5.00) vs. 0.00 (0.00,0.00),all P<0.01],while the number of western medicine doctors was significantly less than that in western medicine hospitals[individuals:4.00 (1.00,7.50) vs. 25.50 (16.00,37.00),P<0.01]. The number of nurses in the emergency departments of hospitals of traditional Chinese medicine and integrated traditional Chinese was significantly less than that of western medicine hospitals[individuals:23.00 (16.00,38.75) vs. 42.00 (30.00,80.00),P<0.01]. The numbers of traditional Chinese medicine nurses,"western medicine nurses learning traditional Chinese medicine" in these hospitals were also significantly higher than those in western medicine hospitals[individuals:1.50 (0.00,5.75) vs. 0.00 (0.00,0.00),1.00 (0.00,7.75) vs. 0.00 (0.00,0.00),all P<0.01],while the number of western medicine nurses was significantly less than that in western medicine hospitals[individuals:15.00 (9.00,25.00) vs. 42.00 (27.00,79.00),P<0.01]. In the situation of medical quality management,the setting rates of emergency clinics,resuscitation rooms and observation rooms in western medicine hospitals were close to those in hospitals of traditional Chinese medicine and integrated traditional Chinese and western medicine,but the setting rates of emergency department wards and emergency intensive care units (EICU) and the number of beds were significantly higher than those in hospitals of traditional Chinese medicine and integrated traditional Chinese and western medicine[setting rate of emergency department wards:70.47％ vs. 53.52％,setting rate of EICU:67.11％ vs. 47.89％,number of beds (individuals):18.00 (0.00,30.00) vs. 2.00 (0.00,12.00) and 8.00 (0.00,12.00) vs. 0.50 (0.00,7.00),all P<0.01]. In terms of the number of visits in 2022,the annual total number of emergency visits (10000 person-times) in western medicine hospitals:6.60 (3.38,12.00) vs. 4.00 (1.25,7.00),the number of visits to the resuscitation room (10000 person-times):0.40 (0.12,1.00) vs. 0.17 (0.05,0.50) and the annual discharge volume of EICU (number of case):216.00 (0.00,550.00) vs. 0.00 (0.00,187.50) were all higher than those in hospitals of traditional Chinese medicine and integrated traditional Chinese and western medicine (all P<0.01). In addition,the success rate of rescue in hospitals of traditional Chinese medicine and integrated traditional Chinese and western medicine was similar to that in western medicine hospitals,and the participation rate of traditional Chinese medicine in the treatment of the resuscitation room was significantly higher than that in western medicine hospitals (P<0.01). In the situation of equipment allocation,hospitals of traditional Chinese medicine and integrated traditional Chinese and western medicine had fewer numbers of equipment than western medicine hospitals (all P<0.01). The proportion of hospitals of traditional Chinese medicine and integrated traditional Chinese and western medicine equipped with non-drug treatment equipment of traditional Chinese medicine was significantly higher than that of western medicine hospitals (all P<0.01). In the application of traditional Chinese medicine techniques and skills,the proportions of hospitals of traditional Chinese medicine and integrated traditional Chinese and western medicine in using Chinese patent medicines,agreed prescriptions,syndrome differentiation and treatment prescriptions,etc. were all higher than those of western medicine hospitals (application rate of Chinese patent medicines:81.69％ vs. 61.74％,application rate of agreed prescriptions:61.97％ vs. 16.78％,application rate of syndrome differentiation and treatment prescriptions:61.27％ vs. 19.46％,all P<0.01). The application rates of decoction pieces,non-decoction agreed with prescriptions,injections,hospital preparations and other dosage forms in hospitals of traditional Chinese medicine and integrated traditional Chinese and western medicine were all significantly higher than those in western medicine hospitals (application rate of decoction pieces:29.58％ vs. 4.70％,the application rate of non-decoction agreed prescriptions:40.85％ vs. 7.38％,application rate of injections:80.28％ vs. 53.02％,application rate of hospital preparations:33.80％ vs. 12.75％,all P<0.01). The application proportions of oral administration,nasal feeding,enema,gastric lavage,external use,intravenous injection,etc. in hospitals of traditional Chinese medicine and integrated traditional Chinese and western medicine were all higher than those in western medicine hospitals (oral application rate:71.13％ vs. 42.28％,nasal feeding application rate:47.18％ vs. 26.17％,enema application rate:48.59％ vs. 19.46％,gastric lavage application rate:21.13％ vs. 6.04％,external use application rate:53.52％ vs. 16.78％,intravenous injection application rate:71.83％ vs. 54.36％,all P<0.01). The application proportions of some drugs such as Shenmai/Shengmai injection,Tianma injection in hospitals of traditional Chinese medicine and integrated traditional Chinese and western medicine were higher than those in western medicine hospitals (application rate of Shenmai/Shengmai injection:59.15％ vs. 35.57％,application rate of Tianma injection:40.85％ vs. 10.07％,application rate of Danshen Honghua injection:30.99％ vs. 14.77％,application rate of Angong Niuhuang pill:26.76％ vs. 12.08％,P<0.01). The proportions of hospitals of traditional Chinese medicine and integrated traditional Chinese and western medicine in carrying out traditional Chinese medicine non-drug treatment operations such as acupuncture,acupoint application,cupping,scraping,bone-setting,moxibustion,press needles,collateral pricking method,etc. were higher than those in western medicine hospitals (application rate of acupuncture:65.49％ vs. 11.41％,application rate of acupoint application:60.56％ vs. 10.07％,application rate of cupping:32.39％ vs. 4.70％,application rate of scraping:28.17％ vs. 2.01％,application rate of bone-setting:26.76％ vs. 10.74％,application rate of moxibustion:24.65％ vs. 5.37％,application rate of press needles:17.61％ vs. 1.34％,application rate of collateral pricking method:16.90％ vs. 0.67％,all P<0.01). Conclusion The proportion of integrated traditional Chinese and western medicine personnel in the emergency departments of hospitals in China is relatively low,and the utilization rate and equipment rate of non-drug treatment of traditional Chinese medicine and traditional Chinese medicine emergency drugs are not high. It is necessary to strengthen the cultivation of integrated traditional Chinese and western medicine skills of emergency department doctors and the application of non-drug treatment of traditional Chinese medicine and traditional Chinese medicine emergency drugs to improve the ability of integrated traditional Chinese and western medicine emergency treatment.

[Objective]To analyse and summarize Professor CHEN Mingxian's clinical experience in the treatment of gastric cancer by"tonifying the spleen and stomach,removing stasis poison,clearing cancer poison".[Methods]Through clinical learning and medical case analysis,this paper elucidates Professor CHEN's understanding of the etiology and pathogenesis of gastric cancer,gives examples of the treatment of gastric cancer,and attaches two cases.[Results]Professor CHEN thinks weakness of the spleen and stomach is a prerequisite for the occurrence of gastric cancer,which runs through the occurrence and development of gastric cancer.Stasis coagulation is the key link for the transformation of precancerous lesions into gastric cancer,and the residual cancer poison is the main pathogenesis of the recurrence and metastasis of gastric cancer.In the treatment,the three methods of"tonifying the spleen and stomach,removing stasis poison and clearing cancer poison"are established,and the flexible fusion application with the syndrome reflects the concept of"always strengthening the body resistance,not forgetting to attack evil and combining prevention and treatment".Two cases of gastric cancer with emaciation after surgery were treated by tonifying the spleen to produce muscle and eliminate distention,removing blood stasis and detoxifying cancer,but each had its own emphasis on strengthening the body resistance and eliminating evil.After treatment,all the cases were stable,and no recurrence and metastasis were observed during follow-up period.[Conclusion]Professor CHEN treats gastric cancer by"tonifying the spleen and stomach,removing stasis poison and clearing cancer poison",which has good curative effect and certain clinical practical value.
