Objectives To investigate the regularity of fluctuation and clinical senses of serum c reactive protein (CRP) level in patients with acute cerebral infarction (ACI) Methods 100 subjects (56 males and 44 females) were divided into five groups including 24 large artery arteriosclerosis (LAA), 27 small artery occlusion (SAO), 2 cardiac embolism(CE), 34 other Certain(OC) and 13 undetermined etiology according to Trial of ORG 10172 in Acute Stroke Treatment (TOAST) Through enzyme linked immunoabsorbent assay (ELISA), we detected and analyzed CRP levels of 100 inpatients Results The risk factors of stroke included coronary heart disease , hypertension, diabetes and intoxication of CO and so on Among the above mentioned, the level of CRP and rate of positive CRP of patients who poisoned by CO was the highest That of coronary heart disease group was lower However, there was no notable difference between hypertension and diabetes groups Conclusions CRP may play a certain role in the occurrence and development of ACI It represents different levels in different types of stroke

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 observe the changes of peripheral blood T lymphocytes,IFN-?,TNF-? and IL-4 in rats infected by T.gondii.Methods 48 Sprague-Dawley(SD)rats were intra-abdominally injected with 2?105/L of cellulose purified living tachyzoites in 2 ml and randomly divided into 8 groups.Six rat was intra-abdominally injected 2 ml of saline as control and 4 rats were remained as normal control.Peripheral blood was collected and the level of IFN-?,TNF-?,IL-4 was analyzed by ELISA on day 1,3,7,14,28,35,42,60.Results Level of IFN-?(6.73 pg/ml)and IL-4(6.91 pg/ml)increased in experimental rats on day 7(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.

Methods SD rats were infected orally with the third?stage larvae of A. cantonensis collected from infected Pomacea canaliculata. Six weeks after the infection the first?stage larvae were isolated and counted from fresh feces of the rats and then were used to infect P. canaliculata. Three weeks lat?er the snails were dissected for counting the third?staged larvae of A. cantonensis. Results The first?stage larvae were detect?ed in the feces of the rats 6 weeks after the infection and the third?staged larvae were successfully isolated after the infection of P. canaliculata. Conclusion The animal model of the entire life cycle of A. cantonensis is successfully established in the labo?ratory with the infection of 50 larvae per rat.

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 investigate the aged-related changes of biochemical mark and bone histomorphology in rats and to explore the effects ofαD3 on aged rats. Methods Sixty male Wistar rats with different age were divided into four groups, including group A (6-week-old male wistar rat), group B (6-month-old male wistar rat), group C (24-month-old male wistar rat) and group D (24-month-old male wistar rat +αD3). Group D was treated with αD3 three times per week for 10 weeks at a does of 0.05μg/(kgrameters. The left femur and mandible were collected for histomorphology. Results Compared with group A, ALP (alkaline phosphatase) and BGP in group B, C and D were decreased with age increased [(87.30 ±12.22)mmol/L VS (257.20 ±92.26) mmol/L, (55.23 ± 18. 18 ) mmol/L VS (257.20 ±92. 26) mmol/L,(46.17 ± 16. 6) mmol/L VS (257. 20 ±92. 26 mmol/L); (4. 37 ± 1.46) ng/L VS (9. 03 ±2. 04) ng/L,(3.80±1.00) ng/L VS (9.03 ±2.04) ng/L, (3.59 ±0.64) ng/L VS( 9.03±2.04) ng/L, P <0. 05]. TRACP5b in group C and D increased more than that in group B [( 15.69 ± 1.62 ) pg/L VS ( 7. 26 ±2.13) pg/L, ( 14.16 ± 1.88 ) pg/L VS ( 7. 26 ± 2. 13 ) pg/L, P < 0. 05]. Testosterone decreased significantly with age increased, but no significant difference was found among four groups. Testosterone was positive related with trabecular area of mandible. Bone gla protein was positive related with alkaline phosphatase and negative related with tartrate - resistant acid phosphatase 5b. Trabecular areas of femur increased in group C and D were greater than that in group B[(220310. 6 ±76360. 50) μm2 VS ( 105093.5 ±73242. 2) μm2, (293085.9 ±68230. 78) μm2 VS ( 105093.5 ±73242. 2) μm2, P <0. 05]. Compared with group B,the trabecular thickness of group C was increased by 53%, while trabecular separation was increased 123%. Trabecular area of group D was increased by 33% compared with group C. Conclusions Theresults showed that bone formation was decreased and absorption was increased with age increased. Testosterone was positive related with trabecular area of mandible. Alfacalcidol had the effects to promote the bone mass of mandible.

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.

Objective To study the effects of lipopolysaccharide(LPS) on the expression of toll like receptor 4 (TLR4), reactive oxygen species(ROS) and on the proliferation of cells as well as secretion of six proinflammmatory cytokines including TNF-α, IL-1, IL-6, IL-8, IL-10, IL-12 levels in SKOV3 cells. And to explore the mechanism of SKOV3 cells in regulation. Methods Cultured primary SKOV3 cells were stimulated with different concentrations of LPS (0.01 μg/ml, 0.1 μg/ml, 1 μg/ml, 10 μg/ml and 20 μg/ml) for 4 h, the TLR4 expression in SKOV3 cells were examined by flow cytometry;1 μg/ml LPS stimulated SKOV3 for 4 h, 8 h, 12 h, 24 h respectively, the TLR4 expression and cell cycle in SKOV3, cell proliferation, ROS level as well as cells and TNF-α and IL-1, IL-6, IL-8, IL-10, IL-12 levels in the culture medium were assayed by flow cytometry, MTT, CBA assay respectively. Results LPS with different concentrations of LPS stimulation in-duced an increased TLR4 expression, however, the expression was reduced when LPS concentration up to 10 μg/ml. LPS stimulation for 4 h, 8 h induced an increased TLR4 expression and cell proliferation. Stimulated for 24 h, however, the TLR4 expression and cell growth were inhibited in S period. Meanwhile, LPS stimulation for 4 h, 8 h, 12 h, 24 h induced a higher ROS secretion in comparison with control group. LPS stimulation induced a stronger cytokine response in comparison with control group, as demonstrated by the production of TNF-α, IL-1, IL-6, IL-8 secretion in cultured SKOV3 cells, while IL-10 and IL-12 with low expression have no obvious difference in the all medium samples. Conclusion TLR4 expression, cell proliferation, ROS and proin-flammmatory cytokine secretion could be induced in SKOV3 through LPS stimulation. The study provide new ex-periment evidences for human ovarian cells SKOV3 immunity regulation and inflammation reaction to promote cells inhibition after LPS stimulation.
