Objective To evaluate gastric bypass on relieving type 2 diabetes mellitus. Methods From September 2009 to September 2010,Thirty two cases of type 2 diabetes mellitus patients underwent gastric bypass operation in Xijing Hospital.Preoperative FBG,2hPG,HbAlc,weight,blood pressure and fatty liver were compared with that on 1 month,6 months,12 months after operation. Result There was no significant postoperative complications.FBG on 1 month,6 months,12 months postop and preoperative level was respectively 7.8 ± 2.2,7.7 ± 2.2,7.2 ± 1.8 and 11.1 ± 2.7 ( mmol/L),P ＜ 0.05.2hPG was 10.2 ± 2.6,10.5±2.8,10.5 ±3.1 and 14.0 ±3.5 (mmoL/L),P＜0.05.HbAlc was 7.6％ ±1.4％,7.5％ ± 1.7％,7.1％ ±1.9％ and9.0％±2.3％,P＜0.05.FBG[(6.9±1.5) mmol/L],2hPG[(10.0±3.2) mmol/L] and HbAlc[ (6.9％ ± 1.9％ ) ] on 12 months after operation were lower than preoperative[ FBG ( 10.7 ± 2.9 ) mmol/L,2hPG ( 14.3 ± 4.1 ) mmol/L,HbAlc ( 8.8％ ± 2.0％ ) ] in patients with BMI ＜25 kg/m2 (P ＜ 0.05 ).In patients with preoperative BMI ≥ 25 kg/m2,FBG ( 7.5 ± 2.3 ) mmol/L,2hPG ( 11.3 ±2.9) mmol/L HbAlc (7.3％ ± 1.9％ ),12 mos pest were lower than that of preoperative levels of [FBG(11.7 ±2.3) mmol/L,2hPG(13.5 ±2.4) mmol/L,HbAlc(9.2％ ±2.7％)] (P ＜0.05).Postoperative blood pressure became normal in 5 out of 6 patients complicating preoperative high blood pressure as evaluated on 12 months after operation. Fatty liver ameliorated in 8 out of 17 patients.Conclusions Gastric bypass significantly improves glycometabolism and comorbidity in type 2 diabetes patients.

Objective To observe the safety and efficacy of enteral nutrition (EN) in patients with hepatic dysfunction in early postoperative period. Methods A total of 52 patients with hepatic dysfunction were divided randomly into EN ( n =26) and PN ( n =26) groups. Patients in the two groups received EN and PN at 6 h after operation, respectively. The changes of hepatic function and conditions of nutrition were measured. The complications and the changes of gastrointestinal function were observed. The time of hospitalization after operation and cost of nutrition were also recorded. Results The level of bilirubin descended faster in EN than that in PN. Both EN and PN could improve the nitrogen balance. The recovery of gastrointestinal function in EN was much earlier than that in PN ( P

Objective To investigate the biological functions of HBeAg-binding protein 1(HBEBP1), suppression subtractive hybridization(SSH) technique was used to screen genes regulated by HBEBP1. Methods HBEBP1(GenBank number:AF529372) was screened and identified by yeast two-hybrid system 3 and co-immunoprecipitation technique. The HBEBP1 coding DNA fragment was amplified by reverse transcription polymerase chain reaction (RT-PCR) technique from HepG2 cell genome. The expressive vector of pcDNA3.1(-)-HBEBP1 was constructed by routine molecular biological methods. The HepG2 cells were transfected with pcDNA3.1(-) and pcDNA3.1(-)-HBEBP1, respectively by using FuGENE6 transfection reagent, then the mRNA was isolated. SSH method was employed to analyze the differentially expressed DNA sequences between the two groups. After restriction enzyme Rsa I digestion, small sized cDNAs were obtained. Then tester cDNAs were divided into two groups and ligated to the specific adaptor 1 and adaptor 2, respectively. After tester cDNAs were hybridized with driver cDNAs twice and underwent polymerase chain reaction (PCR) twice, they were then subcloned into pGEM-Teasy plasmid vectors to set up the subtractive library. Amplification of the library was carried out with E. coli strain DH5?. The cDNAs were sequenced and analyzed in GenBank with Blast search after PCR. Results The subtractive library of genes up-regulated by HBEBP1 was constructed successfully. The amplified library contained 85 positive clones. Colony PCR showed that these clones contained 200-1 000bp inserts. Sequence analysis was performed in 26 clones at random, and the full length sequences were obtained with bioinformatics method. Altogether 15 coding sequences were obtained. Conclusions The obtained sequences may be target genes up-regulated by HBEBP1, among which some genes coding proteins were involved in cell cycle regulation, metabolism, immunity and cell apoptosis. This finding brought some new clues for the study of the biological functions of HBEBP1 and HBeAg.

AIM: To compare the clinical results of suture method and partial eyelash resection treating for pediatric eyelid trichiasis, and screen an effective method for the treatment of pediatric lower eyelid trichiasis.
METHODS: Fifty-six cases of pediatric patients with lower eyelid trichiasis were randomly divided into a control group and an observation group in accordance with the method of drawing lots, and each group was 28 cases. The control group was treated with suture method, and the observation group was treated with partial eyelash resection. The clinical efficacy, patient satisfaction before and after treatment, and the incidence of complications were compared.
RESULTS:(1) The clinically total effective rate was 74%of the control group, which was 89% of the observation group, and there were statistical differences of the clinical efficacy between the two groups ( P<0. 05 ); ( 2 ) the satisfaction scores were (3. 89±1. 22) points and (6. 27±1-86) points of the the control group before and after treatment, which were ( 4. 00±1. 34 ) points and ( 8-95±2-34) points of the observation group, and there were statistical differences of the two groups before and after treatment (P<0. 05), and the scores of the observation group were higher than that of the control group ( P<0-05);(3) complications such as swelling and stitches off appeared in both groups, and the rate was 21% in the control group, which was 11% in the observation group, and there were statistical differences between the two groups (P<0. 05).
CONCLUSION: The treatment of children with lower eyelid trichiasis, suture method is simple and can be performed under local anesthesia in collaboration with children, but with a higher relapse rate, some patients required reoperation;partial resection of eyelashes can be more thoroughly solve the problem of pediatric eyelid trichiasis with low recurrence rate, but children need to be under general anesthesia with some of big risk. So partial resection of eyelashes is unsuitable for using in clinical practice widely and can be used in special cases.

AIM and METHODS: To investigate the effect of electrical stimulation of ventlal septal area (VSA) on discharge of pyrogen - treated thermosensitive neurons in preoptic anterior hypothalamus (POAH) region, the discharging rate of thermosensitive neurons in the POAH region of 32 New Zealand white rabbits were recorded by using extracellular microelectrode techinque. RESULTS: (1) Intraceretroventricularly (i c v) injection of interleukin - 1?(IL - 1?) caused decrease of discharging rate of warm - sensitive neurons and increased in discharging rate of cold - sensitive neurons in POAH regions. (2) These effects could be reversed by electrical stimulation of VSA. CONCLUSION: VSA may play a central role of negative regulation in thermoregulation of pyrogen - treated animal.

Aim To investigate effects of chlorzoxazone on survival and apoptosis of HepG2 cells.Methods The necrosis of HepG2 cells was evaluated by measurement of LDH release.The effects of chlorzoxazone on survival of HepG2 cells were assayed by MTT dyereduction.The effects of chlorzoxazone on cell apoptosis was analyzed by TUNEL method.The ultrastructure of HepG2 cells was observed by transmission electron microscope.Results Chlorzoxazone at concentrations of 100～500 ?mol?L-1 inhibited survival ratios of HepG2 cells in a dose-dependent manner significantly.Typical apoptotic changes were observed in HepG2 cells under the fluorescence microscope and transmission electron microscope.Apoptosis of HepG2 cells was induced after treatment of chlorzoxazone at concentrations from 100 ?mol?L-1 to 500 ?mol?L-1 for 48h,which showed obvious concentration-effect relationship.The apoptotic ratios of HepG2 cells were also increased when chlorzoxazone(100,200,300 and 500 ?mol?L-1) was treated for 24,48 and 72 h,which showed obvious time-effect relationship.Conclusion Chlorzoxazone inhibited HepG2 cells survival and induced cell apoptosis.
