ObjectiveTo discuss the role of transient receptor potential vanilloid 1 (TRPV 1) in the regulation effect of electroacupuncture on gastric motility.MethodTRPV1 gene knock-out mice (KO mice) and wild-type C57BL/6 mice (WT mice) were selected to receive acupuncture at Zusanli (ST36),Quchi (LI11), Zhongwan (CV12), and Weishu (BL21), and the intragastric pressure was observed before and after acupuncture.ResultElectroacupuncture at Zusanli caused both excitation and inhibition in WT mice, predominated by mild excitation, while electroacupuncture at Weishu, Quchi and Zhongwan all caused inhibition effect; in the KO mice, electroacupuncture at Zusanli, Quchi, Zhongwan, and Weishu all inhibited gastric motility.Conclusion TRPV1 bears certain regulating effect on gastric motility, andacupuncture can inhibit the gastric motility in TRPV gene KO mice.

Objective To evaluate the anti-tumour effect of 60℃ LipiodoI in the embolization of VX_2 hepatocarcinoma in rabbits.Methods VX_2 carcinoma cells were surgically implanted into the left liver lobe in 30 male New Zealand white rabbits,which were randomly divided into 3 groups by figure and table method with 10 rabbits in each group.Physiological saline,Lipiodol(37℃),and Lipiodol(60℃)were injected in each group via hepatic artery and liver cancer was embolized.The volume of tumour and serum level of aspartate aminotransferase(AST)were observed after one week,and the survival period of VX_2 rabbits was also observed.Results In the group of Lipiodol(60℃),the growth rate of tumour(0.92? 0.21)was significantly lower than that of control group(3.48?1.17)and Lipiodol(37℃)groups (1.69?0.26),respectively(F=34.95,P0.05),but was significantly higher than the control group(68.6?6.6)U/L(t=19.24,P

OBJECTIVETo evaluate the impact of closed high-pressure suction drainage on the healing of the perineal wound after abdominoperineal resection.

METHODSPatients undergoing rectal abdominoperineal resection in the Wuhan Tongji Hospital from January 2009 to January 2011 were randomized into two groups including the study group(n=61, closed high-pressure suction drainage) and the control group(n=59, presacral drainage). The drainage volume, primary healing rate, and the healing time of perineal wounds were compared.

RESULTSThe total volume of the drainage in the first 3 days was (448.1±142.9) ml in the study group and (548.3±190.6) ml in the control group, the volume of the drainage on the third day was (28.1±12.7) ml and (125.9±84.3) ml respectively. The primary healing rate was 93.4%(57/61) in the study group and 74.6% (44/59) in the control group, the healing time was (13.5±3.5) days and (20.1±5.1) days respectively.

CONCLUSIONClosed high-pressure suction drainage may promote perineal wound healing following rectal abdominoperineal resection.

Objective: To investigate the circadian ryhthm v ariation of 2-125I-iodomelatonin (125I-Mel) binding sites in the human peripheral leukocytes in patients with acute cerebral infarction. Methods: Melatonin binding sites in the human peripheral leukocytes were studied using 125　I-Mel as a radioligand (radioligand binding assays).A ll patients ［age: (70.18±11.70) years］ were diagnosed by CT according to the standard ［Chin J Nerv， 1996,29(6):379］. We also studied 15 age-match ed healthy old people as the control ［age: (68.33±7.76) years］. Resul ts: The circadian ryhthm variation of 125　I-Mel specific binding in control remained significant (P<0.01) with a higher value at midlight ［ (0.16±0.049) fmol/106］ than at middark ［(0.078±0.035) fmol/106］ with one point analysis. There was no significant variation in the patient grou p (P>0.05). The specific binding in the peripheral leukocytes at midlight in the patients with acute cerebral infarction were lower than that of the control . Conclusion: The expression of Mel receptor decreases in the pa tients wit h acute cerebral infarction and the circadian ryhthm variation of 2-125I -Mel appears abnormal.

Bacillus subtilis B6-1 was used as an original strain for mutagenic treatment and a defined medium was used as the selective medium. A mutant named B. subtilis W003 was isolated after three serial ultraviolet (UV) irradiations and one diethyl sulfate (DES) treatment. The ?-PGA yield on a rotary shaker was enhanced from 10.9 g/L in parental strain to 20.5 g/L in the mutant. It was illustrated by single factor experiments that the optimal carbon and nitrogen sources were glucose and (NH4)2SO4 respectively. The optimal fermentation medium was achieved by orthogonal test. In the optimal medium, a ?-PGA yield of 45.3 g/L was obtained after 36 h cultivation.

Objective: To observe the clinical efficacy of combining auricular point sticking and a healthy diet to treat simple obesity in children aged 6-9 years old.Methods: A total of 190 eligible obese kids were divided into an observation group and a control group using the random number table method, with 95 cases in each group. The observation group was intervened by auricular point sticking plus guide on a healthy diet, while the control group was only provided with the guide on a healthy diet. The therapeutic efficacy was observed after intervention for three consecutive months, as well as the changes in body mass (BM), body mass index (BMI), waist circumference (WC), hip circumference (HC), and subcutaneous fat thickness. Results: After the 3-month intervention, the total effective rate was 91.6％ in the observation group, versus 74.7％ in the control group, and the between-group difference was statistically significant (P<0.01); in both groups, the BM, BMI, WC, HC, and subcutaneous fat thickness all decreased significantly (P<0.05), and were lower in the observation group than in the control group, showing statistical significance (P<0.05). Conclusion: Auricular point sticking plus a healthy diet is safe and effective in treating simple obesity in children, producing more significant efficacy than healthy diet intervention alone.
