Objective To study the inhibitory effects of dendritic cells modified by sCD41)gene on T lymphocytes phenotypes and cytokines production and the mechanism of inducing donor-specific immune tolerance in vitro.Methods T lymphocytes prepared with Nylon Fiber Column from Balb/c mice(as reaction cells)and DCs of different groups(as stimulation cells)were subjected to primary mixed lymphocyte culture(MLC).After incubation for 7 days,the responsiveness of the cells was de- tected by MTS method at the indicated time points,and supernatants were assayed for IFN-?,IL-2, IL-4,IL-10 by ELISA kits.On the day 5,the cultured cells were assessed for the expression of CD4, CDS,CD25 and CD69 by using flow cytometry(FCM).After secondary MLC for 5 days,the same indexes were assayed hy using the same methods.Results Dendritic cells modified by sCD40 could in- duce the hyporesponsiveness to alloantigen in primary and secondary MLC.In primary MLC,the ex- pression of CD4~+ and CD8~+ T cells and CD4~+ CD25~+,CD8~+ CD25~+,CD4~+ CD69~+,CD8~+ CD69~+ T cells in IX;modified by sCD40 group were less than those in control group(P

OBJECTIVETo compare the effect of transumbilical single-site single-port with that of transumbilical single-site double-port laparoscopic varicocelectomy in the treatment of varicocele in adolescents.
METHODSWe randomly assigned 80 varicocele patients aged 10 - 16 years to two groups of equal number to receive transumbilical single-site single-port and single-site double-port laparoscopic varicocelectomy, respectively. We compared the operation time, postoperative hospital stay, incisional pain, complications and satisfaction with the abdominal cosmetic outcomes between the two groups.
RESULTSAll the operations were successfully performed. The double-port group showed a significantly higher score on the Visual Analogue Scale than the single-port group (4.8 +/- 1.4 vs 3.6 +/- 1.1, t = -4.986, P < 0.01), but there were no significant differences between the two groups in the operation time ([29.8 +/- 4.2] vs [31.2 +/- 4.6] min, t = 1.383, P = 0.171), postoperative hospital stay ([1.95 +/- 0.7] vs [1.82 +/- 0.8] d, t = -0.784, P = 0.436), complications (0 vs 0) and scores on the satisfaction with abdominal cosmetic outcomes (4.6 +/- 0.6 vs 4.8 +/- 0.5, t = 1.253, P = 0.214). No recurrence, umbilical hernia, hydrocele and orchiatrophy were found in the two groups of patients at 6 months after operation, and no visible scar was observed on the abdominal surface.
CONCLUSIONWith strict surgical indications, single-site single-port and single-site double-port laparoscopic varicocelectomies have similar clinical effects in the treatment of varicocele, which leave no scar on the abdominal surface. Single-site double-port laparoscopy needs no special instruments and therefore is worthier of wide clinical application.

So far there exists no corresponding quality test procedures and grading standards for the seed of Prunus humilis, which is one of the important source of base of semen pruni. Therefor we set up test procedures that are adapt to characteristics of the P. humilis seed through the study of the test of sampling, seed purity, thousand-grain weight, seed moisture, seed viability and germination percentage. 50 cases of seed specimens of P. humilis tested. The related data were analyzed by cluster analysis. Through this research, the seed quality test procedure was developed, and the seed quality grading standard was formulated. The seed quality of each grade should meet the following requirements: for first grade seeds, germination percentage ≥ 68%, thousand-grain weight 383 g, purity ≥ 93%, seed moisture ≤ 5%; for second grade seeds, germination percentage ≥ 26%, thousand-grain weight ≥ 266 g, purity ≥ 73%, seed moisture ≤9%; for third grade seeds, germination percentage ≥ 10%, purity ≥ 50%, thousand-grain weight ≥ 08 g, seed moisture ≤ 13%.

Objective To compare the effect of cimetidine associated with bletilla striata,rhubarb on peptic ulcer,cushingulcer,acute erosive gastritis,bleeding of esophagus and gastric funds varicosis of cirrhotic portal hyper- tension and gastri cancer.Methods 136 patients with upper gastrointestinal hemorrhage were randomly divided into 2 groups.The treated group(n=69)was given cimitidine associated with bletilla striata,rhubarb and the control group(n=67)was given cimitidine only.The effects of hemostasis in 2 groups were observed.Results The effect of hemostasis in the treated group was better than that in the control group on peptic ulcer,cushingulcer,acute ero- sive gastritis and gastric cancer(P<0.05).There were no difference between 2 groups about bleeding of esophagus and gastric funds varicosis of cirrhotic portal hypertension(P>0.05).Conclusion The effect of hemostasis on up- per gastrointestinal hemorrhage treated by integrated traditional Chinese medicine and western medicine might achieve better on cushingulcer,acute erosive gastritis,peptic ulcer and gastri cancer.It has less adverse effect and more safety.
