ObjectiveTo investigate the complication and nursing of intestines nutrition in critical patients after operation. MethodsThe clinical states of 40 patients after operation and being brought to ICU were analyzed.ResultsPatients accepting intestines nutrition presented high incidence of gastrointestinal complications. ConclusionIt is important to pay attention to prevent gastrointestinal complications in patients accepting intestines nutrition early postoperation.

Objective To investigate the clinical value of laparoscopic treatment of myoma in the broad uterine ligament.Methods A retrospective comparison was made on clinical data between 26 patients who had received laparoscopic enucleation of myoma in the broad uterine ligament and 12 patients who had received traditional open resection in the same period.Results Both laparoscopic and traditional operations were successfully completed.As compared with open surgery,the laparoscopic surgery had longer operative time(92.5?15.8 min vs 63.0?15.8 min;t=5.350,P=0.000),similar blood loss during operation(99.2?32.9 m1 vs 91.7?30.7 m1; t=0.667,P=0.509),and shorter time of postoperative hospital stay(4.5?0.7 d vs 7.7?0.9 d;t=-11.960,P=0.000),respectively.Conclusions Laparoscopic enucleation of myoma in the broad uterine ligament is safe and effective and offers a rapid postoperative recovery.

Objective To evaluate the feasibility of laparoscopic hepatectomy.Methods A total of 27 patients received laparoscopic hepatectomy by using laparoscopic Peng's multifunctional operative dissector(LPMOD).Among the patients,13 underwent anatomic hepatectomy(resection of the Ⅱ and Ⅲ segments in 3,Ⅴ segment in 1,Ⅵ in 7,Ⅴ and Ⅵ in 1,and Ⅴ,Ⅵ,Ⅶ,and Ⅷ segments in 1),and 14 received partial hepatectomy.Results The laparoscopic hepatectomy was accomplished successfully in all the patients without converting to open surgery.The mean operation time was 35-360 min [mean,(178.0?78.4) min];intraoperative blood loss was 35-1200 ml [mean,(451.7?332.6) ml];and the postoperative hospital stay was 2-14 d [mean,(8.4?3.0) d].No severe complication occurred after the operation.The postoperative pathological examinations showed hepatic hemangioma in 15,focal hyperplasia of the liver in 2,hepatocelluar carcinoma complicated with liver cirrhosis in 6,intrahepatic bile duct stone complicated with hyperplasia of the bile duct in 2,liver(hematoma) fibrosis in 1,and hepatic angiomyolipoma in 1.The patients were followed up for 1-26 months [mean,(7.9?7.4) months] by using B-ultrasonography or CT.No recurrence of hemangioma or carcinoma,tumor implantation at the puncture site,or residual stones in the intrahepatic bile duct was found in this series.Conclusion By using LPMOD,laparoscopic hepatectomy is safe and feasible for selected patients.

This article analyzed current negative influence on medical students caused by network and the authors put forward 6 pieces of measures to enhance network moral education of medical students,such as establishing and consummating network moral and ethic norm system,strengthening character teaching to medical students by network,promoting construction of resources of network moral education,heightening managing quality of moral educators in high education,cultivating healthy campus network culture atmosphere,and building good online surroundings for medical students by joint of blocking up and dredging.

【Objective】In order to establish the foundation for transgenic mouse model,the human thalassemic gene(β654) was cloned and sequenced.【Methods】The human β654 gene was amplified by PCR,and cloned into the plasmid BGT51 in which the human β gene was cut out aforehand.The recombinant plasmid was certified by enzyme-digestion,reverse dot hybridization and sequencing.【Results】A recombinant plasmid was obtained,which contained the human β654 gene in the correct recombinant direction.Sequencing showed that the cloned insert was correct.【Conclusions】The recombinant plasmid constructed is useful for establishing a transgenic mouse.

The nafion/carbon nanoparticles (CNPs) composite film modified glassy carbon electrode was pre pared by dropwise method, and the electrocatalyst of H_2O_2 at Nafion/CNPs modified electrode was investiga ted.The results show that electrocataytic activitie for detection of H_2O_2 at the modified electrode is very good.The biosensing application of CNPs was demonstrated through fabrication of an electrochemical biosensor.The biosensor was constructed by encapsulating glucose oxidase in the Nafion/CNPs composite film.The biosensor had good electrocatalytic activity toward oxidation of glucose.The glucose biosensor shows a linear range from 2.0 × 10 ~(-6) to 6.0×10~(-3) mol/L with a detection limit of 1.6×10 ~(-6) mol/L.The biosensor shows high stabili ty, good reproducibility and can avoid the commonly coexisted interference.In addition, real rat serum samples were analyzed by this biosensor with satisfactory results.

Objective To observe the effeet of cotransduction of wt-p53,B7-1 and GM-CSF genes mediated by recombinant adenovirus on cell growth, apoptosis and immunogenicity of neuroblastoma cell line SH-SY5Y, Methods We transfected SH-SYSY cells separately with recombinant adenovirus, recombinant adenovirus mediating human wild type p53(wt-p53) gene and BB-102.We separately named them with SH/Ad,SH/p53 and SH/BB-102 group.The protein expression of p53, B7-1 and GM-CSF were measured by Western blot, FCM and enzyme linked immunosorbent assay. Cell number was counted and growth curves were drawed. Cell apoptosis was tested by FCM. Lymphocyte proliferation and cytokine secretory was evaluated by mixed lymphocyte culturing. Results After transection with BB- 102, p53, B7-1, and GM-CSF, high-efficiency expression of target genes were found. Growth of the cells was inhibited, apoptosis was induced in the SH/p53 and SH/BB-102 groups. Proliferation of lymphocytes was stimulated and cytokine increased visorously in the SH/BB-102 group. Condusions After transfection with BB-102, growth of the SH-SY5Y cells was inhibited,apoptosis was induced,and immunogenicity was greatly enhanced.
