Objective:To compare the effect and biotoxicity of tert-butyl acetate (TBA) and ethyl butyrate (EB) on stone dissolution in vitro.Methods:Ten gallstone samples from patients with multiple gallbladder stones were selected and the cholesterol content was analyzed by HPLC. Stone dissolution tests of TBA and EB were performed on cholesterol gallstone in vitro, and the weight of stone at each time point was recorded, meanwhile, methyl tert-butyl ether (MTBE) was used as the control. The inhibitory effects of MTBE, TBA and EB on proliferation of human normal liver cell line LO2 were analyzed by cell proliferation inhibition assay. Flow cytometry was used to analyze the effects of MTBE, TBA and EB on the early and late apoptosis of LO2 cells, and the changes of reactive oxygen species level in LO2 cells were also analyzed.Results:Of the 10 gallbladder gallstones, 6 were cholesterol gallstones and 4 were non-cholesterol gallstones. Stone dissolution experiment showed that the remaining stones of MTBE, TBA and EB groups were (47.83±3.84)%, (58.12±4.53)% and (75.75±4.61)% 30 minutes later. The remaining stones were (18.38±6.47)%, (33.82±6.22)% and (56.38±3.91)% 90 minutes later. MTBE had the best stone dissolution effect in vitro, the stone dissolution effect of TBA was slightly weaker than MTBE, and the stone dissolution effect of EB was relatively weak in all ( P<0.05). The cell proliferation inhibition experiment showed that the cell viability of the control group, MTBE group and TBA group were (100.00±4.46)%, (96.79±4.32)% and (93.72±3.51)%, respectively, and there were no significant differences among the three groups ( P>0.05). However, the cell viability of EB group (87.57±5.29)% was lower than the above three groups, and the differences were statistically significant ( P<0.001). The early apoptosis and late apoptosis of the control group were (1.67±0.15)% and (1.27±0.06)%, respectively. EB induced early apoptosis (15.90±0.53)% ( P<0.001) and late apoptosis (5.13±0.76)% ( P<0.05). However, MTBE and TBA had no significant effect on cell apoptosis ( P>0.05). Compared with control group, MTBE, TBA and EB all significantly inhibited the level of reactive oxygen species ( P<0.05), and the inhibitory effect of EB was the most obvious. Conclusions:TBA has good stone dissolution effect and biosafety for gallbladder cholesterol stones in vitro, while EB has relatively poor performance. TBA is a potential drug for gallstone dissolution.

Objective:To investigate the effect of flexible visiting policies in ICUs by comparing with restrictive visiting policies.Methods:English database (Pubmed, embase, Cochrane library, scopus, OvidSP, Wiley Online library, Google scholar and web of science) and Chinese database (CNKI, VIP, CBM and Wanfang) are retrieved, the search time is up to February 2020. The included literatures were evaluated quantitatively and qualitatively.Results:The flexible visiting policies can reduce the risk of delirium in ICU patients [RR=0.59, 95%CI=(0.36,0.96)], shorten the length of stay [MD=-0.21, 95%CI=(-0.35,-0.06)], improve patients' anxiety symptoms [MD=-2.2, 95%CI=(-3.8,-0.61)], reduce the incidence of anxiety and depression and improve the nursing satisfaction of patients and their families, without increasing the risk of ICU acquired infection [RR= 0.77, 95% CI= (0.51, 1.16)] and patient mortality (RR= 0.82, 95% CI= (0.53, 1.26)]. Sensitivity analysis suggested that the results were stable.Conclusions:Compared with the current restrictive visitation policies, the flexible visitation system can reduce the risk of delirium, improve anxiety symptoms and depression, and obtain more satisfaction from family members and patients, and It can be tried further.

Objective:To explore the regulation effects of baicalin on the behavior as well as extracellular regulated protein kinase(ERK)and cAMP-response element binding protein(CREB) in chronic unpredictable mild stimulus(CUMS) model mice.Methods:Thirty ICR mice were randomly assigned to control(CON) group, model(CUMS) group, fluoxetine(FLU) group, baicalin high-dose(BA-H) group and baicalin low-dose(BA-L) group with 6 mice in each group.In addition to the CON group, the mice in the other four groups were modeled by CUMS method.The modeling was carried out for 42 days, and intragastric administration was carried out according to groups from the 21st day to the completion of modeling.After administration, the depression like behavior of mice was measured by sugar water preference test and water maze test.Western blot (WB) and reverse transcription polymerase chain reaction (RT-PCR) were used to detect the protein level and mRNA level of ERK and CREB in mouse hippocampus respectively.SPSS 21.0 was used for statistical analysis.After normal test and variance homogeneity test, one-way ANOVA was used for multi group comparison, and Tukey test was used for pairwise comparison.Results:Results from the sugar preference experiment showed that compared with CON group, the sugar preference rate of CUMS group was decreased ((82.88±2.00)%, (64.49±1.24)%, t=19.11, P<0.05). Compared with CUMS group, sugar preference rate in FLU group ((81.90±1.19) %), BA-H group (77.86±2.51)%) and BA-L group ((67.98±2.56)%) increased ( t=24.83, 11.68, 3.00, all P<0.05). The results of water maze test showed that compared with CON group, the number of crossing platform ((6.33±0.82), (1.83±0.75), t=9.93, P<0.05) and the target quadrant residence time ((46.83±4.78)s, (24.25±6.12)s, t=7.13, P<0.05) of mice in CUMS group were decreased, but the the escape latency was prolonged ((14.88±3.00) s, (70.70±4.77) s, t=24.26, P<0.05). Compared with CUMS group, the number of crossing platform ((5.00±0.89)times, (5.17±0.75)times and (3.33±0.82) times, t=6.64, 7.67, 3.31, all P<0.05), and the residence time in the target quadrant ((36.80±2.66) s, (36.82±5.62) s, (33.28±3.56) s, t=4.61, 3.71, 3.13, all P<0.05) in FLU group, BA-H group and BA-L group increased, but the escape latencies were shortened ((23.37±4.86) s, (34.83±4.72) s, (62.15±5.30) s, t=17.02, 13.10, 2.94, all P<0.05). WB results showed that compared with CON group, the expression of ERK protein ((1.00±0.15), (0.36±0.10), t= 6.26, P<0.05) and CREB protein((1.00±0.12), (0.29±0.03), t=10.32, P<0.05) in hippocampus of mice in CUMS group decreased.Compared with CUMS group, ERK protein in hippocampus of mice in FLU, BA-H and BA-L groups increased ((0.87±0.05), (0.77±0.08), (0.67±0.03), t=8.25, 5.7, 5.39, all P<0.05), and CREB protein in FLU, BA-H and BA-L groups were also increased ((0.90±0.12), (0.84±0.14), (0.62±0.04), t=8.94, 6.59, 12.25, all P<0.05). qPCR results showed that compared with CON group, ERK mRNA ((1.00±0.03), (0.41±0.10), t=9.78, P<0.05) and CREB mRNA ((1.00±0.08), (0.61±0.12), t=4.62, P<0.05) were decreased in CUMS group.Compared with CUMS group, ERK mRNA in hippocampus of mice in FLU, BA-H and BA-L groups were increased ((0.71±0.08), (0.69±0.03), (0.59±0.04), t=4.15, 4.65, 2.84, all P<0.05), CREB mRNA in FLU group and BA-H group were increased ((0.87±0.08), (0.86±0.07), t=3.14, 3.19, all P<0.05). Conclusion:BA can improve the depression-like behavior of CUMS model mice.The mechanism of action may be related to the regulation of ERK and CREB proteins.

Objective:To investigate the risk factors of non-obstructive gastric retention before endoscopic retrograde cholangiopancreatography (ERCP) in patients with biliopancreatic disease.Methods:The matched case-control study included 109 patients with non-obstructive gastric retention before ERCP as the case group, and 218 patients without gastric retention as the control group. The patients′ medical records including comorbidities, preoperative medication and laboratory indicators were compared between the two groups. Multivariate conditional logistic regression models were subsequently used to determine the risk factors for non-obstructive gastric retention before ERCP.Results:Logistic regression revealed that the jaundice ( OR=12.359, P<0.001), opiates use ( OR=3.009, P=0.001), somatostatin use ( OR=2.445, P=0.033), fasting hyperglycemia ( OR=1.513, P=0.045), hypokalemia ( OR=4.634, P=0.001) and hyponatremia ( OR=1.805, P=0.023) were independent risk factors for non-obstructive gastric retention before ERCP in patients with biliopancreatic disease. Conclusion:Except for gastrointestinal obstruction, jaundice, opiates use, somatostatin use, fasting hyperglycemia, hypokalemia and hyponatremia are all risk factors for gastric retention in patients with biliopancreatic disease. Comprehensive evaluation and early intervention for patients showing these risk factors are needed.

Background: The mouse model of high-fat diet-induced cholesterol gallstone is widely used in researches of pathogenesis, prevention and treatment of gallstones. Aims: To investigate the characteristics and hepatic transcriptomics of the mouse model of high-fat diet-induced cholesterol gallstone. Methods: Twenty male C57BL/6J mice were randomly allocated into chow diet (control) group and lithogenic diet (LD) group. After 8 weeks, the occurrence of gallstone was observed; the serum lipids and gallbladder bile lipids were detected; and the differentially expressed hepatic genes between the two groups were identified with Illumina NovaSeq sequencing systems. The enrichment analysis was mapped in GO and KEGG pathway databases. Real-time PCR was used to detect the expressions of genes related to bile acid synthesis in the liver. Results: The cholesterol gallstone formation rate was 100% in LD group, whereas no gallstone was observed in control group. Hepatomegaly and steatosis were obvious in mice of LD group. The serum levels of total cholesterol and triacylglycerol, as well as the cholesterol content and cholesterol saturation index of the gallbladder bile in LD group were significantly higher than those in control group (P<0.05). A total of 1 330 differentially expressed genes were identified by high-throughput sequencing and bioinformatics analysis. KEGG analysis showed that the differentially expressed genes were mainly enriched in lipid metabolism, bile secretion, and insulin secretion pathways. GO analysis showed that fatty acid metabolic process-related pathways were significantly enriched. Both hepatic transcriptomics analysis and real-time PCR showed that the expression levels of genes related to bile acid synthesis, including CYP7A1, CYP8B1 and CYP7B1 decreased significantly in the liver of LD group as compared with those of control group (P<0.05). Conclusions: The metabolism of cholesterol, bile acids and fatty acids is significantly disordered in mice with cholesterol gallstone. Transcriptomics analysis can screen out the differentially expressed genes that play roles in the formation of cholesterol gallstone, so as to provide references for studies focusing on these topics.

This paper summarized nursing points for caring 12 cases undergoing endoscopic ultrasonography guided biliary drainage(EUS-BD) in the treatment of malignant obstructive jaundice.All patients received EUS-BD after unsuccessful endoscopic retrograde cholangiopancreatography,including 5 patients undergoing EUS guided hepaticogastrostomy(EUS-HGS) and 7 patients undergoing EUS guided choledochoduodenostomy(EUS-CDS).Nursing points included:preoperative assessment,psychological care,preoperative gastrointestinal preparation,intraoperative cardiopulmonary function monitoring,collaboration in operation,postoperative monitoring,observation and nursing care for complications such as bleeding,bile leakage and the others.The average hospital stay was 10～16 d.Two patients developed complications(16.67％).A patient undergoing EUS-HGS developed bile leakage,biliary peritonitis,and pneumoperitoneum after the procedure,but was successfully recovered by placement of a second fully covered self-expendable metal stent in the primary metal stent,percutaneous abdominal drainage and antibiotic treatment.A patient undergoing EUS-CDS developed gastrointestinal bleeding,and was successfully treated with radiological intervention.

Objective To analyze the efficacy of endoscopic ultrasonography-guided biliary drainage ( EUS-BD) for malignant obstructive jaundice and the management of adverse events. Methods Clinical data of 12 patients with malignant obstructive jaundice, who underwent EUS-BD between April 2016 and January 2017, were retrospectively analyzed. All patients received EUS-BD after unsuccessful ERCP, including EUS-guided hepaticogastrostomy ( EUS-HGS ) , EUS-guided antegrade stenting ( EUS-AS ) , and EUS-guided choledochoduodenostomy(EUS-CDS). Procedure outcomes, serum bilirubin and liver enzyme levels before the procedure and 1 week after, complications, treatment results, hospitalization time and follow-up were recorded. Results Two patients underwent EUS-HGS, 3 underwent EUS-AS, and 7 underwent EUS-CDS. Total bilirubin ( t=3. 462, P=0. 005 ) , direct bilirubin ( t=3. 351, P=0. 006 ) , alanine transaminase (t=2. 399, P=0. 037), γ-glutamate transpeptidase (t=3. 256, P=0. 031) reduced significantly after the procedure. Two patients ( 16. 67％) developed complications. A patient undergoing EUS-HGS developed bile leakage, biliary peritonitis, and pneumoperitoneum. A patient undergoing EUS-CDS developed upper gastrointestinal bleeding. Both patients were successfully treated. There were no other adverse events, such as acute pancreatitis, subcutaneous emphysema, pneumothorax and emphysema. No procedure-related death occurred. The mean hospital stay was 13. 75 ± 6. 92 days ( range 5-26 days ) . Conclusion EUS-BD is a safe substitute after unsuccessful ERCP when performed by experienced biliary endoscopists. However, intensive care is necessary after the procedure for early detection and management of complications.
