Objective To explore the regularity of dynamic morphologic changes of the sinoatrial node (SAN) cells of rabbits after the constitution was damaged by formaldehyde wet dressing. Methods Sixty rabbits were randomly divided into 6 groups (n=10 in each group): the control group and 5 experimental groups observed at 2 h, 1, 2, 3, and 4 weeks respectively after the operation. The SAN constitution of rabbits was damaged by 20% formaldehyde wet dressing. The constitutions of SAN were cut quickly at 2 h after wet dressing in the control group and at the corresponding time points in other experimental groups respectively. The specimens were made for light microscopical and electron microscopical observations. The apoptosis of SAN cells was detected by TUNEL method. Results Compared with those in the control group, SAN cells in all experimental groups were damaged at various degrees observed by light microscopy and electron microscopy. Distinct cell tumefaction, soak of grain cells, cytoclasis, hyperplasia of collagen fibers, and other pathological changes were detected. Electron microscopical observation showed distinct pathological changes of the super-micro construction of cells. Apoptosis was not detected in the control group, but various degrees of apoptosis in all experiment groups. The apoptotic rates in all experimental groups were significant as compared with that in the control group (P

Objective To evaluate the value of bypass graft in the treatment of critical lower limb ischemia with distal single outflow artery.Methods Forty-nine lower limbs in 42 patients with single outflow artery were collected and underwent arterial bypass graft.The operation methods included femoropopliteal artificial graft to single outflow artery with autograftand popliteal artery to calf vessel and so on.The results were analyzed finally.Results All of 42 patients,postoperative grafts occlusion occured in 1 case,the occlusion rate was 2.4%(1/42) and the success rate was 97.6%(41/42),1 case died of respiratory failure 4 d postoperatively,the mortality was 2.4%(1/42).The patency rate of graft was 100.0%(41/41) on discharge.Healing rate of foot ulcer was 33.3% (11/33).Conclusions It's difficult to reconstruct blood flow for critical ischemic limb with single outflow artery,but good result is still expected by distal lower limb bypass graft.Distal bypass can provide a better nutritional support for the healing of foot ulcer and result in a lower limb salvage or lowering of amputation level.

Objective To observe the variation of helper T cell (Th)9/regular T cell (Treg cell) balance in the inflammatory process of hepatitis B virus (HBV) infection.Methods Two hundred patients with chronic HBV infection in Zhejiang Hospital of Integrated Traditional and Western Medicine during August 2011 to June 2012 were divided into four groups according to alanine aminotransferase (ALT) levels.:chronic HBV carriers,chronic hepatitis B (CHB) with mildly [upper limit of normal (ULN)<ALT<3 × ULN],moderately (3 × ULN<ALT<5 × ULN),or significantly (ALT>5 × ULN) elevated ALT,with 50 subjects in each group.In addition,30 healthy volunteers were enrolled as healthy controls (HC).ALT levels,HBV DNA,and Th9/Treg levels were measured by automatic biochemical analyzing equipment,real-time fluorescent quantitative polymerase chain reaction and flow cytometry,respectively.Th9/Treg levels of each group were observed.Means between groups were compared by t test,means of multiple groups were compared by one-way analysis of variance.Spearman rank correlation was used for correlation analysis.Results Age,sex distribution and HBV DNA levels of the four groups were comparable (P>0.05).ALT levels of HC were significantly different from those of mildly,moderately,or significantly elevated ALT (t=8.48,18.41,28.93; all P<0.05).Th9 cell levels,Treg cell levels and Th9/Treg ratio of HBV infected individuals were significantly different from those of HC (P<0.05).With the increasing degree of inflammation,proportion of Th9 cells increased and Treg cells decreased gradually.The differences among the four groups were of statistical significance (P< 0.05).Th9 cell level was positively correlated with ALT (r=0.804,P=0.01),while Treg cell level was negatively correlated with ALT (r=-0.828,P=0.01).Conclusions Th9/Treg is imbalanced in patients with HBV infection,and closely correlated with ALT levels.

Objective To explore the effect of reducing sub-clinical infections of Toxoplasma gondii in newborn babies with preventive treatment. Methods Forty-four infected pregnant women were treated in different period and their umbilical blood and/or placenta of their newborn babies were tested for IgG, IgM, cAg and DNA of Toxoplasma gondii. Results The positive rate of Toxoplasma DNA in umbilical blood was 37.8%(14/37). The lowest rate was found in the preventive treatment group with a significant difference compared with the group of general treatment. Conclusion Preventive treatment can reduce sub-clinical infection rate of newborn babies effectively.

B7-H1, a recently described member of the B7 family of costimulatory molecules, is thought to be involved in tumor immune escape by inducing T-cell apoptosis. In order to investigate the relationship between B7-H1 and immune escape of bladder cancer, B7-H1 expression in 50 cases of bladder cancer was detected by using immunohistochemical method. Survival curves were constructed using the Kaplan-Meier method and independent prognostic factors were evaluated using the Cox regression model. Our results showed that the positive rate of B7-H1 immunostaining in normal bladder tissue and bladder cancer was 0 and 72% respectively. The expression of B7-H1 was strongly associated with the pathological grade, clinical stage and recurrence (P<0.05). The survival rate was significantly lower in patients with B7-H1 positive group than in those with B7-H1 negative group and multi-variable analysis revealed that B7-H1 could be regarded as an independent factor in evaluating the prognosis of bladder cancer. It is concluded that the expression of B7-H1 is strongly associated with neoplastic progression and prognosis of bladder cancer. The manipulation of B7-H1 may become a beneficial target for immunotherapy in human bladder cancer.

Objective To establish the mice model of AHL, to investigate the relationship between AHL and the cytoactive factors of the cochlear hair cells in C57BL/6J mice, and to classify the presbycusis models of the C57BL/6J mice. Methods C57BL/6J mice were divided into 6 experimental groups by age (A: 3 months old(m), B: 8 m, C: 9 m, D: 10 m, F: 17 m, G: 18 m) . The auditory functions mice were measured by auditory brainstem response (ABR) with the stimulus click and toneburst at 6 kHz and 8 kHz. 3 months later, Groups C , G, E and H were tested again for ABR. After ABR testing, the cytoactive of the hair cells was detected by succinate dehydrogenase staining and surface preparation technique(two mice from each group except groups C and G). Results The ABR thresholds elevated with age, and the marked change of the cochlea was the degeneration of the cytoactive of the cochlear hair cells, especially those of the outer hair cells. In the beginning, the basement of the basal membrane suffered from the mitochondrion degeneration in the outer hair cells, then it spread to the top region. Subsequently, the inner hair cells were involved. Conclusion C57BL/6J mouse was a typical animal model for the AHL,and the main change of the cochlea was the degeneration of the hair cells, especially the outer hair cells. Thus, C57BL/6J mice can be used as a suitable animal model for the study of presbycusis.
