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.

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.

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.

Objective To investigate the correlation between the formation of pigmented biliary calculus and biliary H.pylori infection.Methods Bile from 35 patients with pigmented biliary calculus and 10 healthy controls was cultured for aerobic,anaerobic and H.pylori.The expression of H.pylori- DNA in bile,bile duct mucosa and pigmented calculus were determined by PCR.The expression of H. pylori associated protein in bile duct mucosa was determined by Western-blot and Warthin-Starry staining.Results H.pylori culture was negative in all bile samples.In 35 patients with biliary pigmen- ted calculus,H.pylori was detected by PCR in the center of calculus,bile and bile duct mucosa of 14.29%,31.43% and 56.67% patients,respectively.Among H.pylori-DNA positive bile samples,7 contained anti-CagA antibodies,and 6 contained Vac A.in addition to Vacuolating cytotoxin(35000), glycoprotein(30000),Urase Band Urase A.Bacteria resembling H.pylori by Warthin-Starry stainning were found in 7 of 30(23.33%)bile duct mueosal samples from patients with biliary pigmented calculus. H.pylori-DNA and its associated protein were not detected in all bile and bile duct mucosae samples from the healthy controls.Conclusions The evidence of H.pylori-DNA and its associated protein in biliary system might indicate the role of H.pylori in the formation of biliary pigmented calculus.

0.05).However,neither CpG-ODN nor hTNF-? failed in improving the expression rates of CD1a.Conclusions CpG-ODN,like hTNF-?,has remarkable im- munostimulatory effect on the differentiation and maturation of monocyte-derived DC from patients with chronic hepatitis B.

Objective To compare laparoscopic appendectomy to conventional operation for the treatment of appendicitis.Methods In this study 1558 patients diagnosed as appendicitis were divided into group A(laparoscopic appendectomy)and group B(conventional operation)according to the random numbers.In group A,779 patients were treated with laparoscopic appendectomy.In group B,779 patients were treated with conventional open appendectomy.The inhospital data and that of followed-up were compared.Statistical analysis was carried out using SPSS11.5 for Windows.Comparisons between categorical variables and continuous variables were analyzed using the X~2 test and t test.Results The operation was successfully performed in all 1558 patients.The operating time in group A and B were(30±2.2)min versus(30±1.6)min(t=0.00,P>0.05),the blood loss were(15±2.9)ml versus(29±5.2)ml(t=65.62,P<0.05),the bed off activity time were(26±3.1)h versus(51±2.1)h(t=69.95,P<0.05),the bowels'move time were(29±1.6)h versus(52±4.6)h(t=10.92,P<0.05),the hospital stay were(3±0.9)d versus(7±1.2)d(t=74.42,P<0.05),the inhospital cost was (6591±41)yuan versus(4860±32)yuan(t=-12.19,P<0.05),the incision infection rate was 0 and 2.8%(X~2=25.40,P<0.05).Postoperative analgesics were needed in 3.8% and 31.4% (X~2=30.63,P<0.05).All the patients were followed-up from 4.5 years to 9.8 years(average 6.8 years).The development of incision hernia in group A and B was 0 versus 0.64% (X~2=5.01,P<0.05).Conclusions Laparoscopic appendectomy is a therapy of choice for patients with acute appendicitis with advantages of minimal invasion,early recovery,few complications and short hospital stay.

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.
