Mannose binding lectin(MBL) is closely related to tumor formation and progression. We and others have confirmed that the MBL gene show differential expression in thyroid cancer. MBL can recognize or bind tumor cells or apoptotic cells, promote clearance of apoptotic cells, and inhibit tumor cells migration and angiogenesis. Thus, MBL can prevent tumor cells invasion and immigration.

BACKGROUND:Glutathione S-transferase can get rid of active oxygen and enhance organism's antioxidative capability.OBJECTIVE:To analyze the association between glutathione S-transferase P1-105 (GSTP1-105)genetic polymorphisms and human exercise capacity in the high altitude environment.DESIGN,TIME AND SETTING:A controlled analysis was performed in the PLA Institute of Physical Education in 2007.PARTICIPANTS:A total of 86 professional mountain climbers who had strong physical performance in the high altitude environment served as experimental subjects.An additional 90 healthy students randomly selected from the PLA Institute of Physical Education served as controls.METHODS:Blood sample was taken from 86 experimental subjects and 90 healthy controls for extraction of genome DNA.GSTP1-105 genetic polymorphisms were detected by polymerase chain reaction-restriction fragment length polymorphism analysis.Distribution of GSTP1-105 alleles and genotypes were compared between experimental and control subjects.MAIN OUTCOME MEASURES:Distribution of GSTP1-105 genotype.RESULTS:Totally 3 GSTP1-105 genotypes were detected:homozygous genotype of the A allele (NA,also called wide type genotype),heterozygous genotype (NG),and homozygous genotype of the G allele (G/G).The frequency of the G allele and variant genotype (A/G+G/G)were significantly lower in the experimental than in the control subjects (P＜0.01).Variant genotype (A/G+G/G)was taken as an exposure factor,then OR=2.19 and 95% CI=1.16-4.13,indicating that in the high altitude environment,the exercise capacity in individuals with GSTP1-105 variant genotype was decreased by 1.19 times than that in individuals with GSTP1-105 wide type genotype.CONCLUSION:GSTP1-105 genetic polymorphisms correlate to human exercise capacity in the high altitude environment.Subjects with wide type genotype have exercise predominance.

Epigenetics, which is called second genetic code precisely and controls the total metabolic processes of eukaryotic cells,has an inseparable correlation with human health and diseases. Among all the gene silencing mechanisms of epigenetic modifications,CpG islands of DNA promoter hypermethylation/histone mod-ifications are two major causes. Promoter methylation of specific genes,such as Ras protein activator analogue 1 may lead to aberrant activation of downstream signaling pathways,following by fibroblasts proliferation and kid-ney fibrosis. In recent years,epigenetic modifications have been proved to play a major role in preventing fibro-blasts to return to their quiescent stage,ultimately contributing to fibrosis in the kidney. This paper provides a glimpse of recent studies on epigenetic mechanisms of chronic kidney diseases,especially renal fibrosis,with an aim to provide new insights into pathogenesis research and clinical diagnosis and treatment.

Toll-like receptor( TLR) ,which belongs to pattern recognition receptor,is type I transmem-brane glycoprotein. TLR activates natural immune and induces several cytokines. Foreign studies have showed that bacterial infection is closely related with TLR. In this paper,the relationship between TLR and bacterial in-fection is reviewd.

BACKGROUND: The ulcer wound is hard to heal in diabetic patients,and it is believed to be caused by the microcirculatory disorder of wound and decreased contents of endogenous growth factors in patients with diabetes mellitus.OBJECTIVE: To observe the biological effects of adeno-associated virus (AAV) mediated transforming growth factor beta1 (AAV-TGFβ1) and vascular endothelial growth factor (AAV-VEGF) in promoting the dermal ulcer healing of diabetic rabbits.DESIGN: A randomized controlled animal experiment.SETTINGS: Medical College, Qingdao University; Affiliated Hospital of Medical College, Qingdao University.MATERIALS: The experiments were carried out in the gynecological laboratory, Affiliated Hospital of Medical College, Qingdao University from July 2004 to January 2006. Twenty-four healthy adult New Zealand rabbits were randomly divided into co-transfection group (n=12) and control group (n=12).METHODS: ① The dermal ulcer models of diabetic rabbits was established by injecting alloxan (130 mg/kg) via ear vein, and the ulcer wound was made by operation. ② In the co-transfection group, the wound was locally infiltrated, and injected with AAV-TGFβ1 virus and AAV-VEGF virus (the concentration was 9×106 virus granules/mL respectively). The rabbits in the control group were treated with injection of saline.MAIN OUTCOME MEASURES: ① The levels of TGFβ1 and VEGF gene transcription in the healing tissue were detected with polymerase chain reaction (PCR) at 1 month postoperatively. ② The capillary density in the wound margin was counted with microcirculation microscope at 3 weeks postoperatively. ③ The collagen Ⅰ and Ⅲ were isolated and detected with Western blotting by protein gel electrophoresis and semi-dry electrophoretic transfer. ④ The content of collagen in the ulcer healing issue was detected at 1 day, 1, 2 and 3 weeks, 1, 2, 3, 4, 5 and 6 months postoperatively. ⑤ The thickness, color and quality of the wound healing were observed postoperatively.RESULTS: All the 24 rabbits were involved in the analysis of results. ① The expressions of TGFβ1 and VEGF gene transcription in the co-transfection group were increased as compared with those in the control group. ② The capillary density at the wound margin in the co-translection group was higher than that in the control group [(19.18±3.56), (6.43±1.52)/mm2,t=3.21, P ＜ 0.05]. ③ The content of collagen Ⅰ in the ulcer healing tissue in the co-transfection group was obviously increased, and the proportion of collagen Ⅰ in the constituent ratio of collagen Ⅱ and Ⅲ was increased.④ The contents of collagen in the ulcer healing tissue at 1 day after transfection were close without significant difference between the two groups (t=1.55, P ＞ 0.05). After that, the contents of collagen in the cotransfection group were all significantly higher than those in the control group (P ＜ 0.05). ⑤ The ulcer healing in the control group was obviously lagged with bad quality.CONCLUSION: The combination of AAV-TGFβ1 and AAV-VEGF can efficiently transfect the dermal ulcer wound in diabetic rabbits, obviously increase the capillary density in ulcer tissue, markedly improve the proportion of collagen I in the constituent ratio of collagen Ⅰ and Ⅲ in healing tissue, and obviously ameliorate the condition of ulcer healing.
