OBJECTIVE: A case of half sibling was determined with multiple genetic markers, which could be potentially applied for determination of half sibling relationship from same father. METHODS: Half sibling relationship was detected by 39 autosomal STR genetic markers, 23 Y-chromosomal STR genetic markers and 12 X -chromosomal STR genetic markers among ZHAO -1, ZHAO -2, ZHAO -3, ZHAO -4, and ZHAO-5. RESULTS: According to autosomal STR, Y-STR and X-STR genotyping results, it was determined that ZHAO-4 (alleged half sibling) was unrelated with ZHAO-1 and ZHAO-2; however, ZHAO-3 (alleged half sibling), ZHAO-5 (alleged half sibling) shared same genetic profile with ZHAO-1, and ZHAO-2 from same father. CONCLUSION It is reliable to use multiple genetic markers and family gene reconstruction to determine half sibling relationship from same father, but it is difficult to determination by calculating half sibling index with ITO and discriminant functions.

Objective To study the effect of nicotine on the expression of αvβ3 integrin in cultured neonatal bovine cerebral microvascular endothelial cells (BCMEC). Methods Flow cytometry was utilized to determine the cell ratio of in vitro cultured neonatal BCMECs adhesive to rat monocytes (MN), after the former were treated with nicotine prior to the incubation with MNs. The effect of niocotine on αvβ3 expression in BCMEC was observed with ELISA. Results In response to 10-5 mol/L ni cotine pretreatment, the adhesive cell ratio of BCMECs to MNs was increased (P<0.05) and enhanced αvβ3 expression was observed, in comparison with those when nicotine of lower concentrations were administered. In contrast, more obvious increase in the adhesive cell ratio and αvβ3 expression was observed when the pretreatment protocol with nicotine (10-7~10-5 mol/L) and IL-1β was adopted, and the effect of nicotine was concentration-dependent. The endothelial adhesion to MNs induced by nicotine and IL-β was obviously blocked by anti-αvβ3 integrin Ab. Conclusion Nicotine may increase the expression of αvβ3 integrin in BCMEC.

· Vascular endothelial growth factor is indispensable inducing factor in retinalangiogenesis. After the retinal neovascularization of proliferative diabetic retinopathy ( PDR ) patients, it can cause fibrovascular membrane formation, epiretinal membrane fibrosis increased, resulting in traction retinal detachment with further aggravate the condition. The recent research suggests that cytokines promote fibroblast proliferation, movement, adhesion, and secretion of extracellular matrix functions in the diabetic state of the environment changes to profibrogenic state, resulting in the accumulation and fibrosis of extracellular matrix. This paper reviewed the status quo of the correlation between vascular endothelial growth factor and fibrosis-related cytokine.

Paeoniflorin is the main active ingredient of Chinese herbaceous peony. This study is to investigate the protective effect of paeoniflorin (Pae) on acute brain damage induced by lipopolysaccharide (LPS) in mice. The mice were randomly assigned to the normal control, model control (LPS), as well as groups of paeoniflorin and lipopolysaccharide (Pae + LPS). Then the mice were administered intraperitioneally with normal saline or Pae (10, 30 mg · kg(-1)) once daily for 6 d. One hour after intrapertioneally treatment on the seventh day, each group were injected LPS (5 mg · kg(-1)) to establish the endotoxin lipopolysaccharide inflammation model except the normal group. The mice were sacrificed after 6 h and the brain homogenates were prepared and measured. The malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), total antioxidant capacity (T-AOC), hydrogen peroxide (H2O2), succinatedehydrogenase (SDH), Na(+)-K(+)-ATPase and Ca(2+)-Mg(2+)-ATPase were dectected by the colorimetric method. The levels of HO-1 and Nrf2 protein in subcellular fractions of brain tissue were detected by Western blot. The results demonstrated that the administration with paeoniflorin reduced the levels of the MDA production; significantly increase the activities of antioxidant enzyme (SOD and GSH-PX). In addition, paeoniflorin could enhance the total antioxidant capacity, decrease the level of H2O2, and increase the activities of SDH, Na(+)-K(+)-ATPase and Ca(2+)-Mg(2+)-ATPase. Furthermore, paeoniflorin can increase the expression of HO-1 and activate the nuclear transfer of Nrf2. Taking together, these findings suggest that paeoniflorin alleviate the acute inflammation in mice brain damage induced by LPS, which is related with its antioxidant effect and improvement of energy metabolism.

Objective To investigate the relation between the cellular immune function and unexplained recurrent spontaneous abortion(URSA) and the mechanism of active immunotherapy on URSA patients.Methods The flow cytometry(FCM) was used to detect CD3+ ,CD4+ ,CD8+ T lymphocyte and CD16+CD56+ natural killer(NK) cell subsets and the ratio of CD4+/CD8+ of peripheral blood(PBL).112 cases with URSA(76 cases treated with active immunotherapy) and 30 cases of normal fertiled(NF) women were studied.The percentages of T lymphocyte and NK cell subsets before and after therapy were compared among 76 cases wtih URSA treated by active immunotherapy.The rate of next successful pregnancy of URSA patients treated with and without active immunotherapy was compared.Results The percentages of CD3+ and CD16+CD56+ cell subsets as well as the ratio of CD4+/CD8+ of the URSA patients were significantly higher than those of NF cases(P <0.05).After active immunotherapy,the percentages of CD3+ and CD56+CD16+ cell subsets as well as the ratio of CD4+/CD8+ of URSA cases were significantly decreased(P <0.05 ).The rate of next successful pregnancy of URSA cases with and without active immunotherapy were 88.2% and 31.2% respectively,the difference was significant(P< 0.05).Conclusion The changes in the percentages of T lympyocyte and NK cell subsets have something to do with URSA.Active immunotherapy can effectively regulate the cellular immune function and increase the rate of next successful pregnancy of URSA patients.

Objective To investigate the loss of heterozygosity at 17 microsatellites of 10 chromosome arms in 68 resected specimens of esophageal cancer, and the relationship to the clinicopathological phenotypes of patients. Methods 68 tumor specimens (20 well-differentiated squamous carcinomas, 30 moderately differentiated carcinomas and 18 poorly differentiated carcinomas) and their matched blood samples were analyzed for LOH at 17 microsatellites by using PCR and fluorescence-based DNA sequencing technology, and the association of LOH with the clinicopathological phenotypes of patients was compared statistically. Results The lowest detection frequency of LOH in our subjects was observed at D8S261 with 33. 3%, and the highest frequency was at D9S125 with 85. 2%. There were 12 markers with the frequency of LOH higher than 50.0%, and 3 markers (D3S1597, D3S1285 and D9S125) with the frequency higher than 75. 0%. There was a significant difference in the frequency of LOH at D9S111 and D13S153 between tumors with different histological grades. LOH at D9S111 was observed in 2 of 12 tumors with well differentiation in 14 of 20 tumors with moderate differentiation, and in 14 of 16 tumors with poor differentiation. LOH at DI3S153 was observed in 2 of 8 tumors with well differentiation, in 12 of 28 tumors with moderate differentiation, and in 11 of 12 tumors with poor differentiation. There was a significant difference in the frequency of LOH at D8S261 between tumors with lymph node metastasis and without lymph node metastasis. LOH at D8S261 was found in 1 of 14 tumors with lymph node metastasis, and in 12 of 22 tumors without lymph node metastasis. Conclusions The widespread and frequent loss of heterozygosity may exist in esophageal cancer, and the candidate genes located in the site of frequent LOH may be involved in the development of this cancer; LOH at D9S11 and D13S153 are more commonly observed in the patients with higher histological grades, the tumors with LOH at D8S261 may have a low tendency to lymph node involvement.
