Objective To probe into methods for postoperatively nursing the patients undergoing pancreaticoduodenectomy combined with vascular allotransplantation. Method The clinical data of postoperative care to 2 patients with pancreatic head carcinoma treated with pancreaticoduodenectomy combined with vascular allotransplantation at the First Affiliated Hospital of Sun Yat-sen University between August 2014 and October 2014 were retrospectively analyzed. Results The two patients lived through the operation, with the operation time of 480 mins, volume of intraoperative blood loss volume of 3000 mL and 600 mL, no complications, hospital stay of 42 days and 27 days. Conclusions The patients undergoing pancreaticoduodenectomy combined with vascular allotransplantation are susceptible to postoperative complications. The nursing care including close observation of disease conditions , drainage tubes care, nutritional care and prevention of complications are critical for the success of operation.

OBJECTIVE:To systematically review the efficacy and safety of Bushen huoxue herb and celecoxib in the treat-ment of knee osteoarthritis, and provide evidence-based reference for clinical treatment. METHODS:Retrieved from CNKI, CBM,VIP and Wanfang Database,Medline,PubMed and Cochrane Library,randomized controlled trials (RCT) about Bushen huoxue herb(test group)and celecoxib(control group)in the treatment of knee osteoarthritis were collected. Meta-analysis was per-formed by using Rev Man 5.3 software after data extraction and quality evaluation. RESULTS:Totally 15 RCTs were included,in-volving 1 129 patients. Results of Meta-analysis showed,the total effective rate [RR=1.09,95%CI(1.04,1.14),P<0.01] and visu-al ache(VAS)score [MD=-0.49,95%CI(-0.94,-0.03),P<0.05] in test group were significantly higher than control group, the differences were statistically significant;there was no significant difference in knee function score [Lequesne:MD=0.24,95%CI (-1.20,1.68),P>0.05;Lysholm:MD=2.32,95%CI(-1.95,6.58),P>0.05;WOMAC:MD=-2.87,95%CI(-6.38,0.64), P>0.05] and the incidence of adverse reactions in 2 groups[RR=0.49,95%CI(0.22,1.09),P=0.08]. CONCLUSIONS:Bushen huoxue herb shows better efficacy and analgesic effect than celecoxib in the treatment of knee osteoarthritis,and is similar to cele-coxib in terms of improving knee function score and safety.

Objective: To investigate the prevalence of metabolic disorder among the high school students in Guangzhou. Methods: A cross-sectional study among 4 620 high school students selected with stratified cluster sampling was conducted in Guangzhou. Height, weight, blood pressure, fasting plasma glucose (FPG) and serum lipid of TC, TG were measured. Household socioeconomic status, medical history, physical activities as well as personal diet and study habits were acquired with structured questionnaire. Results: The prevalence of central obesity was 11.5%. The overall prevalence of IFG and DM was 6.9%. The overall prevalence of both hypercholesteremia and hypertriglyceridemia was 13.4%. The prevalence of hypertension was 11.6%. With multivariable logistic regression, the results showed that: fast eating was associated with increased risk of central obesity (OR=1.79, 95%CI=1.47-2.18) and hypercholesteremia/hypertriglyceridemia (OR=1.27，95%CI=1.04-1.54). While students who ate slow had low risk of central obesity (OR=0.47, 95%CI=0.33-0.68), hypercholesteremia/hypertriglyceridemia(OR=0.71, 95%CI=0.54-0.94) and hypertension (OR=0.65, 95%CI=0.49-0.88). Students with sugar-sweetened beverages once a day or more had higher risk of central obesity (OR=1.60, 95%CI=1.08-2.38) while students without sugar-sweetened beverages consumption had low risk of IFG/DM (OR=0.57, 95%CI= 0.43-0.77) than those who consumed 1-2 times/week. Students without eating out habit had lower risk of hypercholesteremia /hypertriglyceridemia than those with eating out for 1-2 times/week (OR=0.78, 95%CI=0.62-0.98), and students who had lunch out of home or canteen had higher risk of hypercholesteremia /hypertriglyceridemia than those who ate at canteen (OR=1.38，95%CI=1.06-1.81). Conclusion The prevalence of metabolic disorder among high school students in Guangzhou is at a relatively high level. High eating speed, heavy sugared beverages intake and frequently eating out habits are associated with risk of metabolic disorder.

Objective To research the molecular biology characteristics and transient expression in BHK-21 cells of E geue segment from Japanese encephalitis virus(JEV) and construct an eukaryotic expression vector pEGFP-C1-JEV.Methods E gene segment of JEV was amplified by RT-PCR,construct the recombinant vector pEGFP-C1-JEV,which could express EGFP label proteins.Transfect pEGFP-C1-JEV vector into BHK-21 via LipofectAMINETM 2000,to observe expressing of EGFP label protein and transcription of aim gene,and to check up localization and antigenicity of expressed E protein by Immunohistochemistry and Western blot.Results It showed that the recombinant plasmid pEGFP-C1-JEV was successfully constructed and transfected to BHK-21 cells,the normal expression of green fluorescent protein expression rate was higher.RT-PCR showed that gene transcription in BHK-21 and normal expression,expression protein was mainly distributed in the cytoplasm of BHK-21 cells and the envelope in,and can with guinea pig anti-JEV antibody binding.Conclusion pEGFP-C1-JEV vector in BHK-21 cells was normal expression and there were no effect on cell growth and morphology.Meanwhile,on eukaryotic antigens was good antigenicity.This research as a base foundation for E protein gene of JEV eukaryotic expression and function in vitro and applied research.

Objective To compare the differences in the long-term survival rate and the tumor shrinkage rate of inoperable hepatocellular carcinoma (HCC) between transcatheter arterial chemoembolization (TACE) combined with percutaneous ablation therapy and simple TACE therapy in order to provide the basis for the clinical treatment of HCC.Methods Randomized controlled trials (RCT) for comparing the difference in survival rates between TACE plus PA and simple TACE for inoperable HCC were searched from medical literature database,from which the relevant data were extracted.According to Cochrane manual standard,the quality of inclusion literature was evaluated.Results A total of 15 RCT papers were included in this study,including 859 HCC patients.The results of meta-analysis showed that all the 1-year,2-year and 3-year survival rates in TACE plus PA group were better than those in simple TACE group (RR=1.454,95％CI=1.333and 1.586,Z=8.56,P＜0.001;RR=1.781,95％CI=1.511 and 2.099,Z=6.88,P＜0.001;RR=2.351,95％CI=1.808 and 3.059,Z=6.37,P＜0.001,respectively).The tumor shrinkage rate in TACE plus PA group was also better than that in simple TACE group (RR=1.314,95％CI=1.190 and 1.452,Z=5.38,P＜0.001).The sensitivity analysis indicated that the results of the differences in survival rate and tumor shrinkage rate between the two groups were reliable.Conclusion The 1-year,2-year and 3-year survival rates as well as the tumor shrinkage rate of TACE plus PA group are higher than those of simple TACE group.

Obesity is increasingly prevalent globally, searching for therapeutic agents acting on adipose tissue is of great importance. Equisetin (EQST), a meroterpenoid isolated from a marine sponge-derived fungus, has been reported to display antibacterial and antiviral activities. Here, we revealed that EQST displayed anti-obesity effects acting on adipose tissue through inhibiting adipogenesis in vitro and attenuating HFD-induced obesity in mice, doing so without affecting food intake, blood pressure or heart rate. We demonstrated that EQST inhibited the enzyme activity of 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1), a therapeutic target of obesity in adipose tissue. Anti-obesity properties of EQST were all offset by applying excessive 11β-HSD1's substrates and 11β-HSD1 inhibition through knockdown in vitro or 11β-HSD1 knockout in vivo. In the 11β-HSD1 bypass model constructed by adding excess 11β-HSD1 products, EQST's anti-obesity effects disappeared. Furthermore, EQST directly bond to 11β-HSD1 protein and presented remarkable better intensity on 11β-HSD1 inhibition and better efficacy on anti-obesity than known 11β-HSD1 inhibitor. Therefore, EQST can be developed into anti-obesity candidate compound, and this study may provide more clues for developing higher effective 11β-HSD1 inhibitors.
