Objective To understand how Vibrio vulnificus hemolysin (VvhA) affects the viability of murine liver CD4+ T cells as well as its effects on the numbers of mitochondria and the expression of CD62L. Methods The primary murine liver monocytes (MNs) were isolated from C57BL/ 6 mice and then treated with recombinant VvhA (rVvhA) for 6 hours in vitro. The viability of murine liver CD4+T cells and the expression of CD62L were measured by staining with anti-mouse CD4, CD8, CD44, CD62L and cell via-bility fluorescent dye or fluorescent antibody. Moreover, the cells were simply incubated with MitoTracker or JC-1 probes to label mitochondria and mitochondrial membrane potential, which were further analyzed by using flow cytometry analysis. Results With the increase in the doses of rVvhA, the viability of murine liv-er CD4+T cells was decreased from 81. 5% to 15. 8% . The expression of CD62L on the surface of murine liver CD4+T cells was dramatically decreased. Both the murine liver na?ve and effector CD4+ T cells were sensitive to the cytotoxicity of rVvhA. Moreover, treating murine liver CD4+ T cells with rVvhA resulted in significantly decreased numbers of mitochondria and lower mitochondrial membrane potential. Conclusion The cytotoxicity of rVvhA to murine liver CD4+T cells might be achieved through inhibiting the expression of CD62L, decreasing the numbers of mitochondria and lowering mitochondrial membrane potential.

BACKGROUND:At present, scholars general y believe that the physical and chemical properties of titanium mesh are fine as easy plastic, easy cutting, good corrosion resistance and wear resistance, non-magnetic, less effect on CT or MRI results, good histocompatibility and resistance to stress. The titanium mesh is regarded as an ideal material for cranioplasty. <br> OBJECTIVE:To explore the clinical feasibility of primary reconstruction of comminuted and open skul fracture with titanium mesh. <br> METHODS:Sixty-two cases of comminuted and open skul fracture were analyzed retrospectively, including 49 males and 13 females, aged 7-69 years. Among these 62 patients, 30 patients underwent debridement and then after 6-12 months, they received titanium mesh reconstruction, serving as control group. Another 32 cases underwent debridement and titanium mesh reconstruction in the same time as observation group. Al the cases were fol owed-up for 1-2 years to observe wound healing, complications and hospitalization cost. <br> RESULTS AND CONCLUSION:During the fol ow-up, no wound infection and intracranial infection occurred in the two groups. The incidence of intracranial hematoma, epilepsy, and other complications was higher in the control group than the observation group (P<0.05), and the hospitalization cost was also higher in the control group than the observation group (P<0.05). These findings indicate that primary reconstruction with titanium mesh is feasible in the treatment of comminuted and open skul fracture and can significantly reduce the incidence of complications and hospitalization costs.

Aim To investigate the effect of icariin ( ICA) on renal interstitial fibrosis in SHR and explore its mechanism. Methods Fourteen male SHR of 13-week-old were randomly divided into model group( n=7 ) and ICA group ( n=7 ) , and WKY as control group (n=7). One week after adaptive breeding,the rats in the ICA group were given ICA 40 mg·kg-1,ig,bid to 26-week-old. The other rats in the model group and control group were given the same amount of normal sa-line. Then, the morphological changes of the kidney were observed by HE and Masson staining,respective-ly. The contents of plasma aldosterone andⅢcollagen were measured by double antibody sandwich method. The mRNA expressions of TGF-β1 , Smad2 , CTGF and FN were examined by real time RT-PCR. Results Compared with the normal control group, the kidney structures of model group were disordered,the mesang-ial matrix and the tubular interstitial fibrosis were in-creased. The contents of plasma aldosterone and Ⅲcollagen were increased in model group ( P <0. 01 ) . And the mRNA expressions of TGF-β1 , Smad2 , CTGF and FN in kidney tissues were up-regulated in model group( P <0. 01 or P <0. 05 ) . Compared with the model group,the kidney structures were improved and the contents of plasma aldosterone and Ⅲ collagen were reduced, as well as the mRNA expressions of TGF-β1,Smad2,CTGF and FN in kidney tissues were down-regulated(P<0. 01 or P<0. 05)in ICA group. Conclusion ICA may have anti-renal interstitial fi-brosis effect on SHR,and the mechanism might be re-lated to the reduced plasma aldosterone levels and the down-regulated expression of TGF-β1 and Smad2 .
