Objective To evaluate the clinical application of immediate breast reconstruction with the pedicle transverse rectus abdominus myocutaneons(TRAM)flap.Methods Ten breast cancer patients underwent immediate breast reconstruction with the pedicle TRAM flap after mastectomy,among which 4 cases used single pediele TRAM and 6 cases used bipedical TRAM.Polypropypene mesh were applied on all cases of patients to repair the abdominal defect. Results All the breast reconstructions were successful.Complications included grafting flap infection in one case and skin necrosis on partial abdominal skin flap in one case.The reconstructed breasts had a very good shape in 8 cases,and good in 2 cases.No local recurrence and distant metastasis occurred in the patients during the follow-up time ranging from 3 to 15 months. Conclutions Immediate breast reconstruction with the pedicle TRAM flap is an ideal breast reconstruction method for those patients undergoing mastectomy not only because it reconstructs the defective breast but for its cosmetic effect on the abdominal wall.

Objective To evaluate the microRNA role in the pathogenesis of alcohol dependence.Methods By computer retrieval Medline,mirbase,PubMed,Chinese journal full-text database (CNKI),ten thousand database and VIP database,manual retrieval relevant references.Literature retrieval time limit are built from the library until July 2014.English database to Alcoholism,Alcohol Dependence,Alcohol Abstinence,Alcohol Amnestic Disorder Fetal Alcohol Spectrum Disorders,mirna as keywords retrieval;Chinese database to Alcoholism,Alcohol Dependence,Alcohol Abstinence,Alcohol Amnestic Disorder Fetal Alcohol Spectrum Disorders,microRNA,etc.Retrieved from the database to the related literature in July 2014.Results A total of 26 studies were recruited including 8 Chinese literatures and 18 English literatures.Conclusion Abnormal expression of miRNAs will become the next research direction.MicroRNAs may become new biomarker of alcohol dependence on diagnosis,may also makes the molecular drug targets,or the molecular simulation for new drug research and development,this could be for the treatment of alcohol dependence provides a new means.

Objective To compare the surgical effects of laparoscopy and open mini-incision surgery in cholelithotomy with the gallbladder being preserved.MethodsFrom April 2006 to May 2008,63 cases of cholelithiasis received cholelithotomy with the gallbladder being preserved in our hospital by laparoscopy(n=33) or mini-incision open surgery(n=30).The operation time,recovery time of gastrointestinal function,rates of postoperative analgesics use and complications,inpatient charge,and drug expense after the operation were analyzed.ResultsThe mean operation time in laparoscopy group was significantly longer than that in open group [(66.4?10.6) min vs(60.6?9.8) min,t=2.248,P=0.020)].And the inpatient charge in laparoscopy group was significantly higher than that in the open group [(7865?992) yuan vs(6995?825) yuan,t=3.765,P=0.000)].Whereas,the recovery time of the gastrointestinal tract and postoperative hospital stay in the laparoscopy group was significantly shorter than those in the other [(22.7?6.9) h vs(36.9?17.2) h,t=-4.374,P=0.000);(4.8?1.5)d vs(10.0?7.4) d,t=-3.951,P=0.000)].In the laparoscopy group,only one patient showed complication(periumbilical infection) after the treatment,while in the open group,2 patients developed incisional hematoma,2 showed incisional infection,3 had pelvic effusion,and 1 suffered from adhesive intestinal obstruction(?2=5.369,P=0.020).ConclusionsLaparoscopy is a good choice for cholelithotomy with the gallbladder being preserved,for it is minimally invasive,and thus leads to less surgical trauma,quicker recovery,fewer complications,and shorter hospital stay after the procedure.

Objective To determine the content of Ginsenoside Rb1 by RP-HPLC. Methods HPLC was employed with a column of Diamonsil ODS-C18 and a mobile phase of Acetonitrile-H2O (29∶71), the detection wavelength at 203 nm and the column temperature at 25 ℃. Results The linear correlation is available between 0.776 and 7.760 ?g/mL of Ginsenoside Rb1, and the correlation coefficient was 0.999 99, the average recovery was 99.69% and RSD was 2.04% (n=6). Conclusion The method is simple and accurate, and applicable to control the quality of Chanshu Granule.

In order to compare the characteristics of ethano l production, a serie s respiratory deficient mutants (rho -) of Saccharomyces cerevisiae and the ir wil d parent strain (rho +) were assayed for ethanol yield, ethanol fermentation ki netics, ethanol tolerance, and activities of ethanol-dehydrogenase. The data i nd icated that: Though the average amount of ethanol produced by mutants rho - a nd by wild rho + strains were similar, some mutants produced a little more amount of ethanol than wild type. The kinetics curve of ethanol fermentation suggested t h at rho - mutants had a little higher ethanol fermenting speeds than wild type . Th e activity of ethanol-dehydrogenase per unit weight of protein of rho - mutan ts c ells were higher than that of wild strain rho +; the activity of ethanol-dehyd rogenase per unit volume of fermentation medium of rho + were higher than that rho - mutants,mainly due to the higher biomass of rho + were higher than that of rho - mutan ts. Some rho - mutants could tolerate higher ethanol concentration than wild rh o + stra in, but some not. If higher ethanol tolerance and higher ethanol yield rho - mu tants were used in fermenting process,higher ethanol yield would be expected,but some problems such as that rho - mutants grew slowly should be considered.

Objective To compare the graft function of 2 methods of kidney harvesting,the modified method of combined liver and kidney procurement and rapid en bloc kidney procurement. Methods The clinical data of 220 cadaveric renal transplantation recipients were collected(12 months follow-up),174 cases from en bloc kidney procurement and 46 from combined liver and kidney procurement.The average harvesting time,the incidence of renal vein injury,1 year kidney survival and incidence of acute rejection were compared between the two methods.Results In average harvesting time and incidence of renal vein injury,the en bloc kidney procurement were better than the method of combined liver and kidney procurement.However,the method of combined liver and kidney procurement was better than the en bloc kidney procurement in 1 year kidney survival,1 year incidence of acute rejection and average warm ischemia time.There was no difference in 1 year survival of patients and 24 h,1 week and 1 year graft function after transplantation. Conclusion Although the method of combined liver and kidney procurement is better than the en bloc kidney procurement in 1 year kidney survival and 1 year incidence of acute rejection,there is no difference between the 2 methods in 1 year survival of patients and graft function after transplantation.
