Objective To evaluate the effect of laparoscopy in treatment of renal cysts.Methods Twenty- eight and thirty-five patients with renal cysts were performed with transperituneal and retroperitonel laparoscopy,re- spectively.Results A total of 62 patients were treated successfully,the average operation time was 60 minutes,no complications presented,and there was no recurrence in follow-up.Conclusion Laparoseopy survey had the advan- tages of less trauma and fewer complications and rapid recovery in treatment of renal cysts,which was suggested for clinical applications.

BACKGROUND: Recent data suggested that Notch signal pathway plays important regulatory effects in peripheral transplantation immunological response, promotes differentiation of regulatory T cells, induces antigen specific immune tolerance. We proposed that Notch/Notch ligand may play important roles in MHC/TCR interface.OBJECTIVE: To construct the eukaryotic expression vector of rat Deltai gene (Notch ligand), and to examine its expression in dendritic cells.METHODS: The complete encoding cDNA of rat-Delta1 was isolated from bone marrow cells by reverse transcription-polymerase chain reaction (RT-PCR) and this gene was recombined into pcDNA3.1(+) plasmid vector.pcDNA3.1/Delta1 plasmid was transfected into rat dendritic cells with lipofectamine gene transfection method.RESULTS AND CONCLUSION: Double enzyme digestion detection demonstrated that Delta 1 had been successfully constructed in Hindilll and xbal of pcDNA3.1. A positive clone pcDNA3.1/Delta1 was delivered to Shanghai Sangon Biological Engineering Technology & Services Co., Ltd. for sequencing. Sequencing results were identical to Delta1 gene sequence in Genebank, with correct reading frame. The Delta 1 gene-transfected dendritic cells showed similar morphology as their parent cells. Western blotting assay detected that Delta 1 expression was significantly increased in cells. The eukaryotic expression vector pcDNA3.1/Delta1 was constructed, and significant increase of Delta 1 expression was detected after transfection.

Objective To evaluate laparoscopy for insertion of peritoneal catheters in continuous ambulatory peritoneal dialysis (CAPD) patients. Methods Twenty patients of end-stage renal disease.During laparoscopic surgery,the peritoneal catheter was advanced into the abdomen by inducing thread.Results All procedures were completed by laparoscopy successfully. There was no intraoperative complication or surgical mortality. Conclusion Laparoscopy is feasible, safe, and effective for peritoneal catheters placement.

Objective To study the association of single nucleotide polymorphisms (SNPs) of solute carrier family 22 member 4 (SLC22A4) and SLC22A5 genes with Crhon's disease (CD) in Chinese Han nationality. Methods SNPs in the entire coding region of SLC22A4 and SLC22A5 genes were screened by direct DNA sequencing in 80 CD patients and 80 healthy subjects, and statistical in Han population. Five SNPs were found in entire coding region (2 in SLC22A4 gene and 3 in distribution of the alleles and genotypes of SLC22A4 and SLC22A5 polymorphisms between CD patients and healthy controls. Conclusion There is no correlation of SLC22A4 and SLC22A5 with CD in Chinese Han nationality.

Case teaching method has been widely used in clinical medicine teaching.Because of the complicated diseases in elderly patients and the individual differences,it is difficult to achieve the goal of teaching only through several cases.Typical cases of different level are selected according to students' different learning stages and difficulty degree in longitudinal stepped case teaching.The students can gradually understand and master the theoretical knowledge through this method.In addition,their clinical thinking and the ability of solving practical problems can also be trained continuously.Preliminary practice shows that this teaching method is more suitable for the development of modern medical education and the needs of teaching.

Objective To evaluate surgical treatment of infected femoral artery pseudoaneurysm.Methods The data on surgical treatment of 45 patients with infected femoral artery pseudoaneurysm admitted from January 2003 to June 2008 were analyzed retrospectively.Fourty-three patients underwent operative treatment including excision of infected femoral artery pseudoaneurysm,exhaustive debridement and bypass graft with vascular prosthesis.Two patients were unavoidable to undergo removing of infected femoral artery pseudoaneurysm and ligating the proximal and distal artery of pseudoaneurysm because of severe infection and large volume.Results The patients were followed up from 3 to 12 months(mean 7.82 months).The limbs of all the patients underwent bypass graft with vascular prosthesis were salvaged successfully,patients of which had secondary wound healing and had not intermittent lameness.One of two patients performed ligation of artery was salvaged successfully but had severe intermittent lameness,another patient underwent high amputation above knee because of ischemic gangrene.ConclusionFor infected femoral artery pseudoaneurysm,the operative treatment including excision of infected femoral artery pseudoaneurysm,exhaustive debridement and bypass graft with vascular prosthesis is effective and safe.

The clinical teaching of geriatrics is difficult to arouse the students' interest. The flipped classroom teaching method can improve it through the interaction. We used WeChat as a platform for flipped classes and designed a variety of micro lessons. The participation and study interests of students were obvi-ously increased through exchanging teaching, answering questions and discussing. The teaching efficiency was also improved after strengthening practice. The preliminary practice shows that this teaching method can provide students a virtual teaching platform. It not only can enhance the teaching effect, but also can share teaching resources in network even for the long-term cross hospital and cross school exchange promotion.

In this paper, point to point video communication system based on internet is deeply studied. Meanwhile the application system designed practically is introduced. It is emphasized that video compression coding based on low bit rate stream with ITU-T H. 263 agreement and related international standards is realized.

Objective To study the effect of early enteral nutrition (EEN) with ω-3 polyunsaturated fatty acid on nutritional status and body immunity of postoperative patients with colorectal cancer.Methods Forty patients with colorectal cancer were randomly divided into EEN group and parenteral nutrition (PN) group by systematic sampling method with 20 cases of each.The patients in EEN group were given complete enteral nutrition with ω-3 polyunsaturated fatty acid 1-7 d after operation,while the patients in PN group only were given nutrient by regular PN.Nutritional status,body immunity before operation and 1-7 d after operation,and intestinal function recovery time,untoward reaction were determined.Results The postoperative anus first exhaust time and defecate time of patients in EEN group were significantly shorter than those in PN group [(48.0±5.6) hvs.(51.0±6.7) h,(53.0±4.8) h vs.(72.0±3.6) h,P＜0.05].Serum albumin and prealbumin 1 d after operation in 2 groups were significantly lower than before operation (P ＜0.05),but 7 d after operation were significantly higher than 1 d after operation (P ＜0.05).Serum albumin and prealbumin 7 d after operation in EEN group were significantly higher than PN group(P ＜ 0.05).IgG,IgA,IgM,CD3,CD4,CD8,CD4/CD8 1 d after operation in 2 groups were significantly lower than before operation (P ＜ 0.05).IgG,IgA,CD4,CD4/CD8 7 d after operation in EEN group were significantly higher than PN group (P＜ 0.05).Conclusions Compared with the PN,EEN with ω-3 polyunsaturated fatty acid can remarkably improve nutritional status and body immunity in postoperative patients with colorectal cancer.It can accelerate the recovery of intestine function and worthy of recommending.
