Objective To study the expression of MCP-1 in the diabetes mellitus skin defect healing, then discuss its effect. Methods The diabetes mellitus models were established, and the expression of MCP-1 was detected by immunohistochemical staining and Elisa. Results The immunohistochemistry stain showed that the expression of MCP-1 in DM group was higher than that in control group at all time. And the serum value of MCP-1 in DM group had statistical significance ( <0.05) at 3 days or 1 week, but that in 2 weeks and 4 weeks was no statistical significance ( <0.05) . Conclusion The MCP-1 might play a role in the healing of diabetes mellitus skin defect through mediate abnormal inflammatory response.

Objective To analyze the mutations in nucleotide sequences of transfusion transmitted virus(TTV) in neonatal infection.Methods Neonatal serum TTV-DNA was detected by a nested PCR technique.Fifteen Chinese neonates with positive TTV-DNA were diagnosed as TTV infection.ORF1 sequences of TTV-DNA from these neonates were determined.Results Homology of Chinese TTV(C01-C15) and Japanese TTV(N22)isolated ranged from 87.1%-97.7% at nucleotide level,but there were point mutations in Chinese TTV,such as GG→TT in locus 112 and 113,TTATC→CCTAT in locus 236-240.Conclusions Chinese and Japanese TTV isolated had the same genotype.Some gene mutations may increase the TTV pathogen,and result in neonatal hepatitis syndrome or hyperbilirubinemia.

The major goal of microbial ecology is to study the structure and function of complex micro-bial communities. New molecular biological techniques have been successfully applied to analyze mi-crobial community structure. However they do not provide information on the physiologic properties of the detected microorganisms. A new tool for structure-function analyses in microbial ecology, micro-autoradiography combined with fluorescence in situ hybridization (MAR-FISH) can be used to simul-taneously examine the phylogenetic identity and the specific activity of microorganisms within a com-plex microbial community at a single-cell level. This article reviews the principle, experimental steps of MAR-FISH technique. The application of this technique in study of the environmental microbial com-munity and function is also summarized.

Conclusions Endoscopic subtotal thyroideetomy for hyperthyroidism patients is safe,effective and presents a significant cosmetic advantage.

Objective To study the efficiency of iaparoscopic inguinal hernia repair without the use of a mesh. Methods We used laparoscopic hernia repair without the use of a mesh in 92 cases of inguinal hernia. Results were compared with that of total extraperitoneal laparoscopic inguinal hernioplasty(TEP) in 91 cases from January 2001 to March 2004. Results The laparoscopic procedures were successfully performed in all the patients. In mesh-free and TEP group respectively the operating time was (21±4) min vs. (70±16) min (t=28. 01, P<0.05), hospital stay was (3.5±1.0) d vs. (4.8±1.2) d (t=7.96, P<0.05), average time off-bed was (1.0±0.5) d vs. (1.8±0.7) d (t=8.90, P<0.05), duration of pain was (1.0±0.5) d vs. (2.5±0.7) d (t=16.69, P<0.05), the expense was (4500±500) RMB yuan vs. (8000±820) RM B yuan(t=34.89, P<0.05), subcutaneous hematoma rate was 0% vs. 8.7% (χ~2=6.48, P<0.05). The 48 hour C-reaction protein level after the operation was (3.9±0.3) mg/dl and (8.8±0.5) mg/dl (t=80.48, P<0.05). All the difference was statistically significant between the two groups. All patients were followed up for 56.9±6.2 months. The recurrence rate was 0 and 2.1% (χ~2=0.51,P>0.05) respectively. Conclusions Mesh-free laparoseopie inguinal hernia repair is safe, cost-effective, as well as of much lower hernia recurrence.

Objective To study the efficacy of laparoscopic hepatectomy combined with Iodine-125 and radiofrequency ablation(RFA)in the treatment of metastatic hepatic carcinoma.Methods There were 124 patients diagnosed as hepatic metastasis detected by CT or MR scan, and were divided into two treatment groups. Group A(combined group of 41 cases)with laparoscopic excision,RFA and iodine-125 treatment and group B(control group of 83 cases)with transhepatic artery chemoembolization(TACE)and systematic chemotherapy.Results Nine new hepatic metastatic foci were found by laparoscopic ulstrasound during the operation in group A,and in this group,18 hepatic metastatic lesions located on the surface in 13 patients were removed,then RAF applied to the hepatic metastases,and iodine-125 planted in place,altogether 59 foci near to the porta hepatis or large vessels were treated by laparoscopic RFA and iodine-125 implantation.All patients were followed-up from 26 to 45 months(average 35.4 months).The total relief rate was 90.2% and 30.1 % in group A and B respectively(x~2=39.68,P＜0.05＝.The median survival time was 19 and 11 months in group A and B respectively(t=-9.74,P＜0.05＝.The survival rate at 1-,2-and 3-years was 80.5%,48.8%,24.4% and 54.2%,28.9%,9.6% in group A and B respectively (x~2=8.11,4.73,4.81,P＜0.05＝.Conclusions Laparoscopic excision,Iodine-125 implantation and radiofrequency ablation in the treatment of metastatic liver carcinoma is safe、effective,and this approach prolongs the patient's survival time.

Objective To investigate the therapeutic effectiveness of residue liver embedding of iodine-125 on recurrence after hepatectomy in hepatocellular carcinoma patients. Methods In this study, 85 cases with resectable hepatocellular carcinoma were collected and divided into two groups randomly: intrahepatic embedding of iodine-125 group and control group. The serum values of T lymphocyte phenotypes (CD3 + CD4 + ,CD8 +), NK cells,TB IL, ALT, AST, AFP and MMP-9 were measured in all patients 1 day before and 7, 30 days after the operation respectively; B ultrasonic and CT were used to detect for intrahepatic dissemination and recurrence of HCC after hepateetomy. All patients were followed-up from 16 to 55 months (average 35.4 months). Results Surgery were successful in all cases. There were no difference in T lymphocyte phenotypes, NK cells, TBIL, ALT and AST between the two groups (P＞0.05). The serum values of AFP and MMP-9 were much lower in the intrahepatic embedding of iodine-125 group than the control group(P<0.05). In iodine-125 embedding group, the 0.5-, 1-year recurrent rates were 2.3%、6.9%, respectively, compared with 14.2% and 26.1%, respectively, in control group (all P<0.05). Conclusions Intrahepatic embedding of iodine-125 in HCC patients after hepatectomy decreases values of AFP, MMP-9 and local cancer recurrence rate in HCC patients after hepatectomy.
