Background: Postoperative gastroparesis syndrome (PGS) is a common complication after abdominal surgery in patients with primary liver cancer. However, surgeons usually do not have effective treatment for them. Objective: To explore the effects of acupuncture applied to Zusanli and other acupoints on PGS in patients after abdominal surgery. Design, setting, participants and interventions: Sixty-three PGS patients of abdominal surgery, from Eastern Hepatobiliary Surgical Hospital, were randomized into acupuncture group (32 cases) and metoclopramide group (31 cases). The patients in acupuncture group were treated with acupuncture applied to Zusanli and other acupoints once a day, while the patients in metoclopramide group were intramuscularly injected 20 mg metoclopramide three times a day. Main outcome measures: Volume of gastric drainage, number of treatment and cure rate in the two groups were measured and evaluated. Results: Acupuncture and metoclopramide could significantly reduce gastric drainage volume. In acupuncture group, the cure rate was 90.6% and the number of treatment was 6.58+/-4.26, while in metoclopramide group, the cure rate and the number of treatment were 32.3% and 10.13+/-3.60 respectively. There were significant differences in gastric drainage volume, cure rate and number of treatment between the two groups (P<0.05, P<0.01). Conclusion: Acupuncture is a good treatment for PGS, with fewer treatments, high cure rate and rapid effect.

ObjectiveTo investigate the in vivo effects of down-regulating the FGF-21 gene expression by shRNA on glucose and lipids metabolism in high fat diet (HFD) fed ApoE-/- mice.MethoedsMale ApoE-/- mice were randomly divided into chow diet (CF)fed group ( NF,n =10),CF fed + pAd-shFGF-21 group ( NFG,n =9),and HFD fed group ( HF,n =10),HFD fed + Adv-null vector ( pAd-GFP ) group ( GFP,n =6) and HFD fed + pAd-shFGF-21 group ( HFG,n =10).Mice were fed for 16 weeks.C57BL/6J mice were set as control group ( NC group,n=10).NFG,HFG,and GFP groups were injected with pAd-shFGF-21or pAd-GFP by tail vein at the end of 15 weeks.The insulin sensitivity and glucoselipid metabolism were assessed by the hyperinsulinemic- euglycemic clamp technique using 3-[ 3 H] glucose as a tracer at the end of 16 week.ResultsThe plasma FGF-21 levels in NFG and HFG groups were significantly degraded than those in NF and HF groups(20％-27％,P＜0.05),respectively.In the basal state,the fasting blood glucose,fasting plasma insulin,free fatty-acids,triglycerides,total cholesterol,and LDL-C were significantly higher,while the HDL-C was lower in NFG and HFG groups compared with those in NF and HF groups,respectively (P＜0.05 or P＜0.01 ).During the steady-state of clamp,FFA was suppressed in all groups,but it was still higher in NFG and HFG groups than NF and HF groups ( P＜0.05or P＜0.01 ).The glucose infusion rate (GIR)and glucose disappearance rate (GRd)in NFG and HFG groups were significantly decreased compared with NF and HF groups (all P＜0.01 ).In addition,insulin's ability to suppress hepatic glucose production (HGP) during clamps was significantly decreased in HFG and NFG group compared with HF and NF groups (49％ and 20％,respectively; all P＜0.01 ).ConclusionFGF-21 knockdown and low FGF-21 level facilitate the development of metabolic disorder and insulin resistance.
