Objective:To observe the protective effect of Jinbuhuan Jianwei Jiedu Decoction on gastric mucosa of rats with chronic atrophic gastritis (CAG); To explore its mechanism through the farnesyl ester X receptor (FXR)/G protein bile acid coupled receptor 5 (TGR5) pathway.Methods:Wistar rats were randomly divided into normal control group, model group, folic acid group, low-, medium-, and high-dosage groups, with 10 rats in each group. Except for the normal control group, the other rats were used to establish a CAG model by alternate gavage of 2% sodium salicylate+20 mmol/L sodium deoxycholate+methylnitrosoguanidine (MNNG) for free consumption. The folic acid group was treated with 1.43 mg/kg by gavage, while the low-, medium-, and high-dosage groups were treated with 9.68, 19.35 and 38.7 g/kg of Jinbuhuan Jianwei Jiedu Decoction by gavage, once a day, for 12 weeks. The gastric mucosal blood flow and histopathological changes in each group of rats were observed. Rat gastric juice was collected, and gastric juice pH and pepsin activity were detected. ELISA method was used to detect the levels of serum tumor necrosis factor alpha (TNF-α), interleukin-6 (IL-6) and total bile acid (TBA). Western-blot and RT-PCR were used to detect the protein and mRNA levels of FXR, TGR5, CDX2 and SOX2 in gastric mucosal tissue.Results:Compared with the normal control group, the gastric mucosal blood flow and pepsin activity in the low-, medium-, and high-dosage groups increased significantly, and the pH value of gastric juice of medium-, and high-dosage groups decreased ( P<0.05). The levels of TNF-α, IL-6, TBA in serum of low-, medium-, and high-dosage groups decreased ( P<0.05); and FXR, TGR5, CDX2 in gastric mucosal tissue decreased, while the protein expression of SOX2 increased ( P<0.05). Conclusion:Jinbuhuan Jianwei Jiedu Decoction has a repairing effect on gastric function and mucosal lesions in CAG rats. Its mechanism may be related to the inhibition of abnormal activation of FXR/TGR5 pathway, regulation of bile acid and inflammatory mediator secretion.

Objective To provide a comprehensive and multi-dimensional objective assessment of the online medi-cal service quality supplied by public hospitals in China,and providing feasible suggestions for further improving.Methods It adopted a standardized patient method and relied on the IOM model to conduct a descriptive analy-sis of the online medical service quality from the perspectives of safety and effectiveness,efficiency,patient-cen-tered care,and accessibility.Results The process quality(adherence to checklist)in public hospital was 17.65％,the diagnostic accuracy was 66.04％,and the treatment correctness was 88.68％.The average consultation fee was 50 yuan.The patients'disease experience was 4.00 points,the social situation was 0,and the agreement between the physician and the patient was 12.00 points.The average time waiting for first response was about 1.60 hours,the average time waiting for each response was about 5.14 hours,and the patient's total time was about 20.32 hours.The time for response was 3,and the total words of providers was 149.50.Conclusion Internet medical ser-vices quality in public hospital are still insufficient in three aspects:the process quality(adherence to checklist),pa-tient-centered care,and accessibility.Improving online medical service quality can be achieved by strengthening"in-process supervision"and improving physicians'comprehensive clinical ability.

Extracorporeal membrane oxygenation(ECMO)is an important cardiopulmonary support technique.It is the ultimate treatment for heart failure and lung failure after conventional treatment.ECMO enables the body to temporarily replace the pulmonary function and part of the heart function by extracorpore-al gas exchange,and creates a time window for the recovery of respiratory or cardiac function. In 1974, ECMO was first used in neonates.There are many complications in the application of ECMO in neonates, including mechanical complications,bleeding and thrombosis,hemolysis,neurological complications,renal dysfunction,gastrointestinal complications,infection,etc.Long term follow-up found that growth and develop-ment are affected by varying degrees. Timely monitoring,identification of complications and appropriate treatment will improve outcomes.
