ObjectiveTo explore new targets and herbal medicines of total ginsenosides in ameliorating alcoholic hepatitis （AH） by data mining and experimental validation and to provide new directions for the clinical treatment of AH. MethodGSE28619 was selected as the test set from the GEO database and GSE83148 and GSE103580 were selected as the validation sets. The limma package and weighted gene co-expression network analysis （WGCNA） were employed to identify the AH-related differentially expressed genes and modular genes， and Venny was used to extract the common genes. The protein-protein interaction （PPI） network was constructed and the enrichment analysis was carried out. The hub genes were further screened and evaluated for their diagnostic value. After validation with the datasets， new potential targets of AH and traditional Chinese medicine were predicted. Molecular docking between the targets and active ingredients of traditional Chinese medicine was performed， and the results were validated by experiments. Eight out of 48 SD rats were randomly selected into a blank group and received an equal amount of normal saline. The rest rats were subjected to modeling with ethanol by gavage and then randomized into low- （10 mg·kg^-1）， medium- （20 mg·kg^-1）， and high-dose （40 mg·kg^-1） total ginsenosides， model， and positive control （metadoxine， 117 mg·kg^-1） groups. After 3 weeks of gavage， serum samples were collected for the measurement of aspartate aminotransferase （AST） and alanine aminotransferase （ALT） levels， and liver samples were collected for hematoxylin-eosin （HE） staining. Western blot and Real-time PCR were employed to determine the protein and mRNA levels， respectively， of potential targets in the liver tissue. ResultData mining predicted the potential genes： Proto-oncogene FOS and collagen type Ⅰ alpha 2 （COL1A2）. Experimental validation showed that the liver injury was alleviated after drug administration compared with that after modeling. The serum AST and ALT levels were reduced after drug administration. The protein and mRNA levels of FOS were significantly up-regulated， while those of COL1A2 were down-regulated after drug administration. ConclusionTotal ginsenosides ameliorate HA via FOS and COL1A2.

Objective To explore the possible mechanisms of myocardial injury induced by simulated weightlessness in space flight and the recovery of myocardium in rats by aerobic exercise intervention.Methods The body weight of rats was weighed using an electronic balance;the cardiac function indexes of rats in each group were detected using echocardiography and isolated cardiac perfusion;and the expression of proteins related to the AMPK/ULK1/Beclin1 pathway in the myocardial tissues of rats in each group was detected using Western Blot.Results(1)When compared with the C1 group,the T1 group not statistically significant in body weight(P?>?0.05),and the wet weight of the flounder muscle,the wet weight-to-weight ratio of the flounder muscle,and the heart weight were all significantly decreased(P??0.05).After 4 weeks of aerobic exercise,when compared to group C2,group R showed a significant rise in the expression of AMPK and ULK1(P??0.05),and a rise in the expression of Beclin1,but not statistically significant(P?>?0.05);and group A showed a slight increase in the expression of AMPK,ULK1 and Beclin1 expression decreased slightly but not statistically significant(P?>?0.05),p-AMPK expression decreased significantly(P??0.05),and a significant decrease in the expression of ULK1(P??0.05);the expression of p-ULK1 decreased significantly(P?

Objective Exploring the relationship between pain recurrence after percutaneous radiofre-quency thermocoagulation and the degree of trigeminal nerve atrophy and pontine angle in patients with primary trigeminal neuralgia(INT).Methods A retrospective analysis was conducted on 297 patients with INT admitted to Qingdao Haici Hospital Affiliated to Qingdao University(Qingdao Traditional Chinese Medicine Hospital)from January 2020 to December 2021.All patients received percutaneous radiofrequency thermocoagulation surgery in our hospital.They were followed up for 24 months,during which 56 patients experienced pain recurrence after sur-gery(recurrence group),while 241 patients did not experience postoperative pain recurrence(non-recurrence group).Results The length of the trigeminal nerve root,degree of trigeminal nerve atrophy,and the combined application of the two were used to draw ROC curves.The AUC values predicted for pain recurrence in INT patients after percutaneous radiofrequency thermocoagulation were 0.553,0.750,and 0.861,respectively.The results of the logistic regression model showed that shortened trigeminal nerve root length(OR=0.624,P=0.038),increased degree of trigeminal nerve atrophy(OR=2.257,P=0.000),multi vessel compression(OR=1.842,P=0.019),and severe baseline pain(OR=1.714,P=0.000)were independent risk factors for pain recurrence in INT patients after percutaneous radiofrequency thermocoagulation(P<0.05).Conclusions INT patients undergo thin-layer MRI scans before surgery,and the degree of trigeminal nerve atrophy has a higher predictive value for pain recur-rence after radiofrequency thermocoagulation.The length of trigeminal nerve roots and degree of trigeminal nerve atrophy are correlated with postoperative pain recurrence in patients.

Objective To investigate the effects of oral probiotics on gut microbiota diversity,colony structure,and intergroup differences in mice with subcutaneous colon cancer tumors,based on 16S rRNA sequencing technology.Methods Twenty-four 6-week-old male BALB/c mice were divided randomly into normal control group(NC group,n = 8),model group(M group,n = 8),and probiotic + model group(PM group,n = 8)after adaptive feeding for 1 week.Mice in the PM group were given 200 μL probiotic mixed solution(Bifidobacterium longum and Lactobacillus delbrueckii subsp.bulgaricus mixed lyophilized powder,2×108 colony-forming units)by gavage three times/week for 7 weeks,while the M group and PM group received 200 μL normal saline.At 10 weeks old,0.2 mL CT26.WT cell suspension(1×107/mL)was inoculated subcutaneously into the left hind limbs of M group and PM group,while NC group were inoculated with 0.2 mL normal saline.The general state of mice was observed,the growth of subcutaneous tumor was monitored,and the changes of intestinal flora structure were detected by 16S rRNA sequencing.Results The subcutaneous tumors of the M group were prominent,and the subcutaneous tumor volume and weight of the PM group were significantly reduced(P<0.05).Compared with NC group,Alpha diversity index was lower in the M group,and a significant difference of Beta diversity inter groups(P<0.01).And supplementation of probiotics had a certain effect on gut microbiota diversity in the M group.Compared with M group,the relative abundance of Bacteroidetes,Proteobacteria,Muribaculaceae,Bacteroides were higher in the PM group,while the relative abundance of Firmicutes,Desulfobacterota,Lachnospiraceae_NK4A136_group,Alistipes were lower in the PM group.LEfSe analysis showed that Muribaculaceae and Bacteroides in the PM group were different species with high abundance(LDA values>4).Conclusions Oral probiotics may improve the gut microbiota by increasing the relative abundance of beneficial Muribaculaceae and Bacteroides in subcutaneous tumors in mice with colon cancer.

Objective:To summarize the clinical features and prognosis of acute kidney injury in patients with HBV related acute on chronic liver failure (ACLF).Methods:A total of 150 patients who developed acute kidney injury (AKI) in patients with HBV related ACLF from Sep. 2010 to Sep. 2019 were reviewed retrospectively, and the gender, age, laboratory examination, Child-pugh scores, and model for end-stage liver disease (MELD) were collected and the survival of the patients were followed up to analyze the prognosis.Results:Ninety-three percent of the patients were complicated with ascites, 81% with spontaneous peritonitis, 65% with hepatic encephalopathy and 58.7% with pulmonary infection; 60 patients (60.0%) were AKI stage 1, 44 patients (29.3%) were AKI stage 2, 16 patients (10.7%) were AKI stage 3. The patients with hyponatremia had lower albumin ( t=2.571, P=0.011), higher blood urea nitrogen, serum potassium and white blood cell levels than those without hyponatremia ( t=3.184, P=0.002; t=2.069, P=0.040; t=2.251, P=0.026); 74.7% of the patients died within 30 days, and the 90 days survival rate was 16.7%. The 30 days and 90 days mortality of patients with hyponatremia was higher than that of patients without hyponatremia ( χ2=4.11, P=0.044; χ2=3.901, P=0.049 7). Kaplan-Meier analysis revealed that the patients who had abnormal uric acid pre-diagnosis of AKI, hyponatremia when diagnosis of AKI, organ damage other than liver and kidney, metabolic acidosis, upper gastrointestinal tract bleeding, hepatic encephalopathy had a poor survival. Cox regression analysis showed that other organ function damage other than liver and kidney, metabolic acidosis, and the old age, were independent risk factors of death. Conclusions:Most of the AKI patients with HBV related ACLF had ascites and spontaneous bacterial peritonitis when AKI occurred, and AKI stage 1 was common. The mortality of patients with hyponatremia was high, and the risk of death was high in patients with severe organ damage other than liver and kidney, metabolic acidosis and the old age.

ObjectiveTo investigate the prevalence rate of gallstones among university teachers in Tianjin, China, and related risk factors. MethodsPhysical examination data were collected from the teachers from five universities who participated in physical examination in Physical Examination Center, Tianjin Medical University Cancer Institute and Hospital, in 2015, and abdominal ultrasound was used for the diagnosis of gallstones. The chi-square test was used for comparison of categorical data between groups. Univariate and multivariate logistic regression analyses were used to identify the risk factors for gallstones in the teachers from different universities, and a meta-analysis was used for the pooled analysis of prevalence rate and risk factors. ResultsA total of 8006 university teachers were enrolled, among whom 440 were diagnosed with gallstones, and the pooled prevalence rate of gallstones was 5.5%. The meta-analysis showed that hypertension (odds ratio ［OR］=1.67, 95% confidence interval ［CI］: 1.32-2.12, P＜0.001), fatty liver (OR=1.39, 95%CI: 1.12-1.72, P＜0.001), kidney stones (OR=1.90, 95%CI: 1.15-3.14, P=0.01), and high levels of hexokinase (OR=1.42, 95%CI: 1.03-1.94, P=0.03), alanine aminotransferase (OR=1.32, 95%CI: 1.01-1.73, P=0.04), and globulin (OR=1.74, 95%CI: 1.08-2.79, P=0.02) were risk factors for gallstones. ConclusionThere is a relatively low prevalence rate of gallstones among university teachers in Tianjin, and hypertension, fatty liver, kidney stones, and high levels of hexokinase, alanine aminotransferase, and globulin may be the risk factors for gallstones.

Methods: According to the industrial engineering theory and program analysis method, combined with the characteristics of nursing professional, define the name of the activity, build the evaluation index and formula of the nursing process level, the workday practice method was used to investigate and analyze the nurses′ work processes in a total of 48 departments in four hospitals in Tianjin. Results: The overall nursing process level of Tianjin Third Grade A General Hospital was: β = 0.756. Among them, the process utility coefficient was: β₁=0.913, and the coherence coefficient is only: β₂=0.627. There were differences in the level of nursing processes between different hospitals and departments. Among them, the process coherence level was different and the overall level was low. Conclusions The level of nursing procedures in Tianjin Third Grade A General Hospital needs to be improved. It is necessary to improve the continuity of nursing work, appropriately increase the reserve talents, strengthen the standardized training of nursing procedures, and explore more flexible scheduling methods. Conditional hospitals and departments can explore the application of information technology in nursing work or implement an unaccompanied mode to reduce the workload of nurses and improve the continuity of the nursing process, thereby improving the level of nursing processes and improving the quality and efficiency of nursing work.

Objective: To explore and construct the cognitive response model for patients suffering conflicts with nurses, and to provide guidance cues for the prevention and treatment of nurse-patient conflict. Methods: According to the grounded theory approach devoloped by Strauss, a total of 9 patients were observed and interviewed in a semi-structured way, and the collected data was analysed to extract the cognitive response theme. Results: A cognitive response model for patients with nurse-patient conflicts was established, which included three phases, i.e., the demands of expectations, the emotional catharsis, and the introspection of right and wrong. Conclusion The established congnitive response model confirmes the relationships among environmental factors, patients′ cognitive processes, and patients′ reponse, and can be used to prevent and deal with the conflicts between patients and nurses.
