Objective To explore different intervention methods on the risk factors of cardiovascular disease for women with severe pre-eclampsia history.Methods 78 patients with a history of severe preeclampsia in the hospital from November 2006 to November 2008 were chosen as the research subject.They were divided into the observation group and the control group according to the adopted different methods of intervention with 39 patients in each group.The control group was taken with conventional interventions for obesity intervention,and the observation group was treated with standard behavior therapy (SBT).The improving situations of the related risk factors for cardiovascular disease after three months for the two groups were compared.The effect of different intervention methods on the risk factors of cardiovascular disease was evaluated for women with severe pre-eclampsia history.Results After the intervention,the cardiovascular risk factors (systolic blood pressure,body mass,waist circumference,fasting glucose,total cholesterol/high density lipoprotein) of the two groups improved significantly than before the intervention.But the improvement effect of the observation group was better than the control group,the differences between the two groups were significant.Conclusions The intervention effect on risk factors of cardiovascular disease by standard behavior therapy for women with severe pre-eclampsia history is better than conventional way,which is worthy of clinical application.

In order to find out appropriate model to best disseminate laparoscopy for colorectal cancer clinical advanced technologies,it is necessary to establish a whole set of training system,which included selecting training site,intensive training,operation observation,advanced study at home and abroad,technical support,etc..Evaluation was based on operation time,hemorrhage in surgery,other injuries in surgery,conversion to open surgery and the ratio of in situ relapse in one year post surgery.These five indexes were compared between the training group and the control group with the gradually stable trend of learning curve as standard.Without previous laparoscopic surgery experience,the training group required 13.8±0.75,14±0.89,10.2±0.74,16.4±0.49 and 20.4±0.49 cases,respectively,to achieve expected proficiency,and the control group required 28.6± 1.69,29.2±1.16,27.8 ± 0.74,22.8 ± 0.40 and 25.4± 1.03 cases,respectively.The learning time required 13.4± 1.02 months on average for the training group and 27.8±2.13 months for the control group.In conclusion,the training system achieved obvious superiority to the controls to achieve expected skills and proficiency in laparoscopy for colorectal cancer.

Objective To evaluate the clinic application effects of laparoscopy in the diagnosis and treatment of abdominal difficult and complicated diseases.Methods The clinical data of 64 cases of agnogenic abdominal diseases underwent laparoscopic exploration and biopsies were retrospectively analyzed.All the patients were difficult cases to diagnose,who have one or more clinical situations,such as abdominal pain,ascites of unknown origin,abdominal mass and intestinal obstruction,and obscure hemorrhage of small intestine.Results Definite diagnosis was made in 62 patients after laparoscopy (96.9％).In patients with ascites,abdominal mass,intestinal obstruction and hemorrhage of small intestine,the definite diagnostic rate were 93.3％,100.0％,100.0％ and 6/6,respectively.The complication rate of laparoscopic exploration was 1.6％ (1/64).Underwent laparoscopic exploration,14 of 64 cases (22％) were treated by operation.Among them,8 cases (8/14) were treated by therapeutic laparoscopy,and other 6 cases (6/14) were treated by abdominal surgery without any comliactions.Conclusion Laparoscopic exploration is safe and effective in diagnosis and treatment of abdominal difficult and complicated diseases.

Objective To express human cytotoxic T lymphocyte associated antigen-4 (CTLA4) extracelluar domain in Bacmid-baculovirus expression system. Methods The cDNA of human CTLA4 extracelluar domain was isolated from plasmid pUC19-CTLA4Ig by PCR.The specific cDNA was subcloned into plasmid pFastBacl. The insertion was confirmed by DNA sequencing, and then transposed into Hz8 Bacmid in DH10B. The recombinant Bacmid was used to transform Hz insect cells. The supernatant and cellular lysate were analyzed by using SDS-PAGE. Results A specific protein in the cellular lysate of Hz insect cells containing human CTLA4 extracelluar domain with MW38 x 103 was found. Conclusion Human CTLA4 extracellular domain is expressed in the Bacmid-baculovirus expression system.

Objective The aim of this study is to evaluate the accuracy of EUS in rectal cancer restaging after neoadjuvant therapy. Methods EUS staging was performed after neoadjuvant therapy in 61 patients who were diagnosed as having local advanced rectal cancer. All patients underwent subsequent surgi-cal resection and complete pathologic staging. Results Compared with pathological staging, the total accura-cy of post-therapy EUS T-staging was 59.0% (36/61). The T-overstaging rate was 36.1% (22/61) and un-derstaging rate was 4.9% (3/61). Accuracy of EUS N-staging was 68.9% (42/61), N-overstaging and un-derstaging rates were 14.7% (9/61) and 16.4% (10/61), respectively. Conclusion The accuracy of EUS restaging for rectal cancer after neoadjuvant therapy is relatively low.

Objective To explore the effect of timeliness motivation theory-based continuing care on the self-care ability and healthy behavior in elderly patients with type 2 diabetes. Methods A total of 202 elderly patients with type 2 diabetes in our hospital were selected,and were randomly divided into observation group and control group according to the random number table, with 101 cases in each group. The control group were given healthy related education during hospitalization , and post-discharge telephone follow-up every month, lasting 10~15min each time.The observation group were additionally given timeliness motivation theory-based continuing care by telephone follow-up each month , including emotional arousal , need motivation , examples stimulating and benefit motivation, lasting 6 months. Their self-care ability and healthy behavior in the two groups were compared. Result The self-care ability in the observation group was significantly significantly better than that of the control group (P<0.001), and had significantly much more healthy behaviors than the latter (P < 0.001). Conclusion Timeliness motivation theory-based continuing care can improve the self-care ability and healthy behavior in elderly patients with type 2 diabetes.

Objective To find the different plasma-associated proteins of rheumatoid arthritis (RA) by using two-dimensional gel electrophoresis for understanding the pathogenesis of RA. Methods The total protein from either RA patients or normal ones was prepared by means of immobilized pH gradient based on two-dimensional gel electrophoresis. After silver staining, gel-image analysis was performed by using PDQuest. The differentially expressed proteins were identified by matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF-MS). Results 2-DE patterns of plasma from controls and RA patients were presented. The results showed that average number of protein spots was 592 and 563 respectively, and the corresponding average matching rate was 89% and 87% respectively. Gel-image analysis revealed that there were 24 differential protein spots. A total of 15 differential protein spots were successfully identified by MALDI-TOF-MS, of which 6 proteins were up-regulated as compared with control. Conclusion The differentially expressed proteins can be observed in plasma from RA and controls, which can be used to elucidate the pathogenesis of RA for further study.

A new type of gastric electrical stimulator (GES) was introduced. After the stimulator was implanted in beagle dogs, its stimulating effects and the pathological changes at the implant site were observed to study the safety and efficacy of stimulator as well as the tissue compatibility of the materials used. The results showed that, this type of stimulator was safe and capable of inhibiting food intake of the dogs, and that the materials used had good tissue compatibility.
