Objective To study the effects of oral rehydration with the solution of pyruvate-glucoseelectrolyte (PGES) by comparison with the bicarbonate-glucose-electrolyte solution (BGES) on resuscitation in rats with lethal hemorrhagic shock.Methods Sixty adult male SD rats with intra-gastric tube,and cannulation of femoral artery and vein were subjected to 45％ total blood volume loss from the femoral artery,and then randomly divided into three groups (n =20 in each group):no fluid resuscitation group (NR),oral fluid resuscitation with the PGES group (PGES) and oral fluid resuscitation with the BGES group (BGES).In NR group,the animals received no fluid replacement or any other treatment.Rats in PGES and BGES groups were infused intra-gastrically with pre-warmed PGES or BGES in volume of 2 times shed blood given at 30 min after hemorrhage and completed within 6 hours.Blood samples in each group were collected from the abdominal aorta before or at 0,1,2,4 h post hemorrhage to detect serum alanine aminotransferase (ALT),creatinine (Cr),creatine phosphate kinase isoenzyme (CK-MB) and intestinal fatty acid binding protein (iFABP).Another 84 rats randomly divided into four groups:NR group (n =24),PGES group (n =24),BGES group (n =24),and no hemorrhage group (NH group,n =12).Rats in the three hemorrhage groups were treated the same as described above,and the rats in NH group underwent the same surgical procedure without hemorrhage were served as the sham group.All these rats were observed for their 24-hour survival rates.Results The 24-hour survival rates of PGES and BGES groups were both significantly higher than the rate of NR group (11/24 vs.1/24,x2 =18.087,P ＜0.01 ; 5/24 vs.1/24,x2 =6.445,P ＜ 0.05) ; the survival rate of PGES group was also significantly higher than that of BGES group (11/24 vs.5/24,x2 =4.02,P ＜ 0.05).All levels of ALT,CK-MB,Cr and iFABP in both the NR group and two oral resuscitation groups at 1 h,2 h and 4 h post hemorrhage were significantly higher than those before the blood loss,respectively (P ＜ 0.01).These biomarkers at 2 h,4 h post hemorrhage were significantly lower in the PGES and BGES groups than those in NR group (P ＜ 0.01) ; the serum levels of ALT,CK-MB,Cr and iFABP were significantly lower in the PGES group than those in the BGES group at 2 h and 4 h post hemorrhage,respectively (P ＜ 0.05).Conclusions Present results demonstrated that the pyruvate-enriched oral re-hydration solution (ORS =PGES) was more effective in preserving the organ function and prolonging the animal survival after resuscitation of lethal hemorrhagic shock in comparison with the bicarbonate-containing ORS (BGES).The oral re-hydration solution (PGES) recommended by the World Hygiene Organization (WHO ORS) may require further improvement in oral resuscitation of shock and the PGES may be recommended as a choice of oral re-hydration salts in the treatment of lethal hemorrhagic shock when intravenous administration is not available.

Objective To evaluate whether Vitamin B supplementation could prevent ischemic stroke recurrence.Methods Randomized controlled trials (RCTs) observing Vitamin B supplementation in patients with stroke was performed in databases including ScienceDirect, PubMed/Medline, China National Knowledge Infrastructure, Chinese Biomedical Data-Base, Wanfang Database, and VIP Chinese Science and Technology Journal Database to find related studies in English or Chinese published before August 2016. The patients in control group received a placebo or basic therapy without Vitamin B, and those in experimental group was treated with Vitamin B alone or Vitamin B on the basis of conventional treatment. The data were collected by two researchers independently and the quality of studies was assessed by the modified Jadad Scale. The Meta-analysis was performed using Stata 12.0, funnel plot was drawn, and Egger and Begg regressions were used to evaluate the publication bias, and sensitivity was also analyzed. Results Seven RCTs studies were enrolled to analyze with a total number of 9846 stroke patients, 4755 patients in control group, and 5091 in experimental group, respectively. ① Vitamin B supplementation for prevention of recurrent stroke: heterogeneity test results showed a heterogeneity in literatures enrolled (I2 = 62.9%,P = 0.009), and a random effect model was used for Meta-analysis. It was shown that the incidence of recurrent stroke in the experimental group was significantly lower than that in the control group [pooled relative risk(RR) = 0.64, 95% confidence interval (95%CI) = 0.47-0.87], which indicated that the supplementation of Vitamin B could prevent the recurrence of stroke. Cumulative Meta-analysis showed that Vitamin B supplementation exhibited positive effects in the prevention stroke recurrence from 2012. The 95%CI tended to be stable while demonstrating good change trend as sample growing. The publication bias evaluation results showed that the funnel plot was not symmetrical by visual inspection, further quantitative analysis showed thatP value from Egger regression was 0.008, while that from Begg regression was 0.035, bothP < 0.05, suggesting there were some publication bias. The sensitivity analysis showed that the overall results were stable and reliable. ② The effect of Vitamin B supplementation on plasma homocysteine (Hcy) levels in stroke patients: heterogeneity test results showed a heterogeneity in literatures enrolled (I2 = 96.2%,P = 0.000), and a random effect model was used for Meta-analysis. It was shown that compared with control group, the plasma Hcy levels of patients after Vitamin B supplementation in experimental group were significantly decreased [pooled weighted mean difference (WMD) = -6.92, 95%CI = -9.11 to -4.73), indicating that Vitamin B could significantly reduce plasma Hcy levels in stroke patients. Cumulative meta analysis showed that, as time went on, the relevant research samples were increased, 95%CI tended to be stable and the variation tendency was better. The publication bias evaluation results showed that the funnel plot was symmetry by visual inspection, and further quantitative analysis showed that theP value from Egger regression was 0.345, and that from Begg regression was 0.764, bothP > 0.05, which indicating that there was no evidence of publication bias in the study included.Conclusions Vitamin B supplementation was associated with a lower risk of recurrent stroke in stroke patients and could significantly improve the quality of secondary prevention of stroke. Furthermore, supplementation of Vitamin B could reduce plasma Hcy levels in stroke patients which might contribute to its effect in preventing stroke recurrence.

Objective To investigate the clinical value of percutaneous gallbladder drainage in the treatment of severe acute pancreatitis(SAP). Methods A total of 65 patients treated for SAP in our hospital between January 2014 and April 2017 were analyzed retrospectively. The patients were divided into a gallbladder puncture group and a control group. Follow-up was performed for at least 6 months to monitor mortality and the incidence of complications, including pancreatic abscess, pseudocyst, renal failure, respiratory failure, heart failure, gastrointestinal bleeding, sepsis, and disseminated intravascular coagulation (DIC), The differences in mortality and complication rates between the two groups were statistically analyzed. Results Mortality in the gallbladder puncture group was significantly lower than in the control group (P ＜ 0. 05); the incidence of renal failure, respiratory failure, heart failure, gastrointestinal bleeding, and sepsis in the gallbladder puncture group was lower than in the control group (P ＜ 0. 05); the incidence of pancreatic abscess and pseudocyst in the gallbladder puncture group was similar to that in the control group, showing no significant difference (P ＞ 0. 05); the incidence of DIC in the gallbladder puncture group was lower than in the control group, but the difference was not statistically significant (P ＞ 0. 05). Conclusion Percutaneous gallbladder drainage can effectively reduce the incidence of renal failure, respiratory failure, heart failure, gastrointestinal bleeding, and sepsis in SAP, thereby reducing mortality. However, the incidence of DIC, pancreatic abscess, and pseudocyst is not reduced.

Objective:To investigate the expression of adenosine 5'-monophosphate-activated protein kinase (AMPK) phosphorylation in corneal epithelial cells and the effects of fungus on AMPK phosphorylation and interleukin-6 (IL-6) production in corneal epithelial cells.Methods:The human immortalized corneal epithelial cell line was selected.The safe concentration range of AMPK agonist 5-aminoimidazole-4-carboxamide 1-β-D-ribofuranoside (AICAR) (100, 300, 500, 1 000 μmol/L) and inhibitor Compound C (10.0, 12.5, 15.0, 17.5, 20.0 μmol/L) on corneal epithelial cells was screened by multi-function real-time unlabeled cell analyzer.Corneal epithelial cells without any treatment were used as the normal control group, and those co-cultured with spores were used as the spore control group.Corneal epithelial cells co-cultured with spores were treated with AICAR and Compound C for 4 hours in the AICAR group and Compound C group, respectively.The expression of phosphorylated AMPK (p-AMPK) and AMPK in corneal epithelial cells was detected by Western blot, and the concentration of IL-6 in the culture supernatant was determined by enzyme-linked immunosorbent assay (ELISA).Results:After treatment with different concentrations of AICAR for different periods, there was no statistical significance in the cell index of corneal epithelial cells (all at P>0.05). The cell index of corneal epithelial cells was increased with 10.0 μmol/L and 12.5 μmol/L Compound C treatment compared with that of the normal control group.The expression levels of p-AMPK were 0.67±0.15, 2.57±0.12, 3.67±0.58 and 1.50±0.50, respectively, in the normal control group, spore control group, AICAR group and Compound C group, showing a statistically significant difference among them ( F=32.820, P<0.001). The expression level of p-AMPK was significantly higher in the spore control group compared with the normal control group ( P<0.001). The expression level of p-AMPK in the AICAR group was higher than that in the spore control group, and the expression level of p-AMPK in the Compound C group was lower than that in the spore control group, and the differences were statistically significant (both at P=0.010). There was no significant difference in the relative expression level of AMPK among the four groups ( F=0.120, P=0.950). The expression levels of IL-6 concentration in the normal control group, spore control group, AICAR group and Compound C group were (107.81±17.15), (156.32±9.94), (167.96±14.16) and (127.42±19.75)pg/ml, respectively, showing a statistically significant difference among them ( F=15.210, P<0.001). The IL-6 concentration of the spore control group was higher than that of the normal control group, and the difference was statistically significant ( P<0.001). The IL-6 concentration of the AICAR group was higher than that of the spore control group, but the difference was not statistically significant ( P=0.260). The IL-6 concentration of the Compound C group was lower than that of the spore control group, and the difference was statistically significant ( P=0.010). Conclusions:In corneal epithelial cells, AMPK phosphorylation is found, which is enhanced after fungal spores stimulation, and the secretion of IL-6 increases.

ObjectiveBy exploring the volatile components， polysaccharide composition and changes in the contents of five carbohydrate components of Polygonatum cyrtonema rhizoma before and after processing， and then the effect of yellow rice wine on the odour formation of P. cyrtonema rhizoma was investigated. MethodThe volatile components of P. cyrtonema rhizoma before and after processing were detected by headspace gas chromatography-mass spectrometry（HS-GC-MS）， and sample data were subjected to principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA） using SIMCA 14.1， then the differences between these components of P. cyrtonema rhizoma before and after processing were screened according to the principle of variable importance in the projection（VIP） value>1. Crude carbohydrate components in raw and wine-processed P. cyrtonema rhizoma were subjected to oxime and silylation， the carbohydrate components were analyzed by gas chromatography-mass spectrometry（GC-MS/MS）， and the relative contents of various components were calculated by peak area normalization， then quantitative analysis of four carbohydrate components was also carried out. ResultA total of 23 volatile components were identified from the raw products and the wine-processed products， including 15 components in raw products and 20 components in wine-processed products. Among them， 2-methylbutyraldehyde and isovaleraldehyde had a sweet odor and their contents increased after processing， but the contents of hexanal and caproic acid decreased， new components such as 2-acetylfuran and 5-methylfuranal were produced after processing. PCA and OPLS-DA results showed that there were significant differences between raw products and the wine-processed products， a total of 13 differential compounds were screened out， of which 7 showed an upward trend in relative content and 6 showed a downward trend. A total of 7 carbohydrate components， including 5 monosaccharides and 2 disaccharides， were identified in raw products and the wine-processed products. The results of determination showed that the contents of fructose， glucose， mannose and sucrose in P. cyrtonema rhizoma increased after wine-processing， and their increases were 4.54， 1.51， 2.93， 3.66 times， respectively. ConclusionAfter processing， the increase of aromatic flavor of P. cyrtonema rhizoma may be related to the increase of the contents of aldehydes such as 2-methylbutyraldehyde and isovaleraldehyde， while the decrease of raw flavor may be related to the decrease of the contents of volatile components such as hexanal and hexanoic acid， the increase of sweet flavor may be related to the increase of the contents of monosaccharides and oligosaccharides such as fructose and sucrose.
