Objective To establish the HPLC fingerprints of petroleum ether parts from five traditional medicine (Alpinia officinarum Hance, Alpinia galangal ( L.) Wild, Alpinia galanga Will., Alpinia katsumadai Hayata, and Alpinia oxyphylla Miq), and to explore the similarities and differences of chemical composition,as well as the correlation between the genetic relationship and the chemical composition. Methods HPLC method was used to analysis the five traditional medicines. The data were evaluated by using the"similarity evaluation system for chromatographic fingerprint of TCM" software. Results The similarity chemical composition from Alpinia officinarum Hance,Alpinia galangal(L.) Wild,Alpinia galanga Will.,Alpinia katsumadai Hayata,and Alpinia oxyphylla Miq in ethyl acetate were 0.741,0.855,0.610,0.510, 0.680,respectively. Conclusion Though there were differences of fingerprint peak of petroleum ether parts between five the traditional Chinese medicines, similarities were also observed among them.

OBJECTIVETo conduct a systematic review of the safety and efficacy of enhanced recovery after surgery(ERAS) program in perioperative management of pancreaticoduodenectomy.
METHODSA computerized search was performed in databases including PubMed, Embase, Medline, Web of Science, Cochrane Library, CNKI, Wanfang and VIP for randomized controlled trials (RCTs) or clinical controlled trials (CCTs) describing an ERAS program in patients undergoing pancreaticoduodenectomy published between January 1966 and May 2014. After assessment of methodological quality and data extraction, meta-analysis was performed using RevMan 5.2.0 software.
RESULTSSix RCTs and 8 CCTs including 2565 patients were selected for this study, including the study group(n=1366) and the control group (n=1199). Compared with the control group, the study group had a shorter length of hospital stay(WMD=-3.67, 95% CI:-5.66--1.68, P<0.05), lower postoperative complication rate(OR=0.73, 95% CI:0.56-0.95, P<0.05) and lower mortality(OR=0.63, 95% CI:0.44-0.91, P<0.05). However, no significant differences existed in mortality, readmission rate and re-operation rate between the two groups.
CONCLUSIONSEnhanced recovery after surgery programme in perioperative management of pancreaticoduodenectomy is safe and effective. But due to the medium quality of the literature. This still need more rigorously designed RCTs to prove the safety and efficiency of ERAS programme for the patients undergoing pancreaticoduodenectomy.

OBJECTIVE: To observe the improvement effects of water extract of Glycyrrhiza uralensis on acute hepatic injury caused by triptolide and its effects on the levels of IL-10 and TNF-α in rats. METHODS: A total of 60 healthy male SD rats were randomized into blank control group, model group, positive control group (magnesium isoglycyrrhizinate) and G. uralensis water extract low-dose, middle-dose and high-dose groups. Blank control group and model group were given isochoric normal saline intragastrically; positive control group was given Magnesium isoglycyrrhizinate liquid intragastrically (13.5 mg/kg); G. uralensis water extract low-dose, middle-dose and high-dose groups were given G. uralensis water extract intragastrically 1 mL (120, 240, 480 mg/kg, by the amount of extract), qd, for consecutive 7 d. At 8th day of administration, model group, positive control group and G. uralensis water extract groups were given Triptolide liquid intragastrically (0.6 mg/kg) to establish acute liver injury model. HE staining was used to detect the pathological changes of liver tissue in rats. The activities of ALT and AST in serum were determined by enzyme coupling reaction. The protein expression of IL-10 and TNF-α in liver tissue were analyzed by Western blotting. RESULTS: Compared with blank control group, obvious pathological changes of liver tissue in rats were observed in model group; serum activities of ALT and AST, the protein expression level of TNF-α in liver tissue were increased significantly, while the protein expression level of IL-10 was decreased significantly (P<0.01). Compared with model group, pathological changes of liver tissue were relieved significantly. Except for the activity of AST in serum of rats in G. uralensis water extract low-dose group, the activities of ALT and AST in serum, the protein expression level of TNF-α in liver tissue were decreased significantly in G. uralensis groups, while the protein expression level of IL-10 in liver tissue was increased significantly (P<0.05 or P<0.01). CONCLUSIONS: G. uralensis water extract can relieve triptolide-induced acute liver injury in rats, the mechanism of which may be associated with expression down-regulation of pro-inflammatory factor TNF-α and expression up-regulation of anti-inflammatory factor IL-10.

Objective:
To investigate the association between the whole blood riboflavin level and the occurrence, development and prognosis of esophageal squamous cell carcinoma (ESCC) in China.
Methods:
From March 2014 to September 2018, ESCC patients from three hospitals (the Affiliated Hospital of Medical College of Shantou University, Shantou Central Hospital in Southern Chaoshan area and First Affiliated Hospital of Zhengzhou University in Northern Taihang Mountain) were selected as a case group; non-esophageal patients who had a physical examination were selected as a control group. The case and control group were paired by age (±5 years) and a 1:1 ration. A total of 1 528 subjects were enrolled including 764 patients in the case group and 764 patients in the control group. About 3-5 ml venous blood samples were collected, and the erythrocyte glutathione reductase activity coefficient (GRAC) was measured to assess the whole blood riboflavin level. A multivariate conditional logistic regression model was used to analyze the association between the GRAC and the risk of ESCC. The association between the GRAC and the prognosis of ESCC was analyzed by using Cox proportional risk regression model based on 288 patients with complete survival data. They were divided into two groups, the high GRAC group (GRAC≥7.87) group and the low GRAC group (GRAC<7.87) according to the strongest correlation between the total survival time, survival outcome and GRAC (GRAC=7.87).
Results:
Among the 1 528 patients, 958 patients were from Southern Chaoshan area, including 479 patients in the case group with an average age about (59.90±9.34) years and 479 patients in the control group with an average age about (59.55±8.77) years. Other 570 patients were from Northern Taihang Mountain area, including 285 patients in the case group with an average age (58.39±5.19) years and 285 patients in the control group with an average age about (58.74±4.57) years. The multivariate conditional logistic regression showed that the
