Objective To study the effect of con tinuous passive motion (CPM) on joint function after arthroscopy in the knee jo int. Methods Arthroscopy examinations and operations were performed in 53 patients. They were divided into study and control groups based on the use or not of CPM immediately in the postoperative period. The cont rol group consisted of 25 patients treated without postoperative CPM and the stu dy group consisted of 28 patients treated with CPM postoperatively. Range of mot ion (ROM) and the comprehensive function score of the knee joint were evaluated preoperatively, at discharge and at three months after operation. Results There were statistically significant differences in the f unction score of the knee joint between the two groups at discharge. The mean f lexion and extension in the study group were 90.64??16.57? and -0.71??3.78 ?, respectively, compared to 69.40??15.17? and -4.32??4.71? in the contro l group. The mean of the comprehensive function score of the knee joint in the c ontrol group were 11.24.compared to 8.89 in the study group. Seventy-five perce nt (21 cases) of the patients in the CPM group and 24% (6 cases)of patients in t he control group had achieved 90? of flexion at the time of hospital discharge. Conclusion CPM had enhanced the therapeutic effects of arthroscopy in the knee joint and shortened the length of stay of the patie nts in the hospital. Further investigation is needed for evaluating the long-te rm effect of CPM.

BACKGROUND:There are many positive effects by activation of peroxisome proliferator activated receptor-gamma (PPARγ) signal pathway in cardiovascular system. Angiotensin II is closely related with myocardial fibrosis, however, there are few articles demonstrating that the activation of PPARγsignal pathway can weaken the expression of angiotensin II to improve the radiation-induced heart injury. OBJECTIVE:To evaluate the effect of angiotensin II type 1 receptor in the rat model of radiation-induced heart injury after PPARγsignal pathway is activated. METHODS:Sixty rats were randomly and equal y divided into five groups:control, pioglitazone, model, radiation+low-dose pioglitazone, radiation+high-dose pioglitazone. In the model, radiation+low-dose pioglitazone, radiation+high-dose pioglitazone groups, rats received 6 MV high energy X-ray irradiation at the range of 1.5 cm × 1.5 cm and the irradiation dose of 300 cGy/min, for 6 hours. Furthermore, rats in the radiation+low-dose pioglitazone and radiation+high-dose pioglitazone groups were given 10 and 20 mg/kg pioglitazone by lavage, for 30 days;rats in the model group were given 2 mL distil ed water. In the pioglitazone group, rats were treated with 10 mg/kg pioglitazone by lavage. RESULTS AND CONCLUSION:After rats were treated with pioglitazone, the heart injury and the heart fibrosis in the irradiated rats were decreased. The expressions of angiotensin II type 1 receptor mRNA and protein in the heart tissue were down-regulated. Experimental findings indicate that, pioglitazone intervention downregulates the expression of angiotensin II type 1 receptor in the rat models of radiation-induced heart injury and activation of PPARγsignal pathway al eviates the radiation-induced heart injury.

Objective To observe the time-course expression of calcium-calmodulin dependent protein ki-naseⅡδ (CaMKⅡδ) in cerebral cortex after traumatic brain injury (TBI). Methods The TBI rat model was established. The expression of CaMKⅡδ in cerebral cortex around injured area was tested by Western blotting and immunohistochemical staining . Results Western blotting revealed expression of CaMKⅡδ in normal rat brain cortex. It gradually increased after TBI, peaked after 3 days, and then returned to normal level. The result of immunohistochemical staining was consistent with that of West-ern blotting. Conclusion The expression of CaMKⅡδ around injured area after TBI increased initially and then decreased. It could be used as a new indicator for wound age determination following TBI.

Background Conjunctivochalasis is an age-related inflammatory ocular surface disease manifesting redundant,loose conjunctiva folds.Studies showed that conjunctivochalasis often accompanies with inflammatory response,indicating that a variety of inflammatory cytokines are involved in pathogenesis of conjunctivochalasis.Objective This study attempted to investigate the expressions of pentraxin-3 (PTX-3) and tumor necrosis factor-α stimulated gene-6 (TSG-6) proteins in fibroblasts of conjunctivochalasis.Methods The protocol was approved by Ethic Committee of Putuo Hospital affiliated Shanghai University of Traditional Chinese Medicine.Thirteen eyes of 13 patients with conjunctivochalasis,16 eyes of 16 patients with age-related cataract and 16 eyes of 15 patients with pterygium were included in Putuo Hospital Affiliated to Shanghai University of Traditional Medicine from January,2011 to June,2012.The samples of conjunctival tissue were collected in the patients during surgery under the informed consent,and fibroblasts were cultured and passaged by explant culture method.Content of PTX-3 and TSG-6 proteins in cell supernatant was detected by ELISA.Results Translucent poor,dark black area was around the cell overflow.Cultured cells of third generation showed long shuttle type,uniform size,radiated out in all directions,and oval nuclei was sited in the cytoplasm,surrounded by varying the length of cross-linking of cell processes.The concentrations of PTX-3 protein in cell supernatant were (2 182.33 ± 738.68) pg/ml in the conjunctivochalasis group,which were higher than (738.32±335.00) pg/ml in the age-related cataract group and (981.37±416.04)pg/ml in the pterygium group,showing a significant difference among the three groups (F =6.474,P=0.032).The contents of TSG-6 proteins in cell supernatant were (59.10±6.52) pg/ml,(53.99± 11.16) pg/ml and (35.01±5.33)pg/ml in the conjunctivochalasis group,pterygium group and age-related cataract group,with a significant difference among the three groups (F =7.421,P =0.024),and contents of TSG-6 proteins in the agerelated cataract group was lowest,however,no significant difference was found in the TSG-6 contents between the conjunctivochalasis group and the pterygium group (P＞0.05).Conclusions Inflammatory reaction participates in the pathogenesis and development of conjunctivochalasis,up-regulation of PTX-3 and TSG-6 expression in fibroblasts might partakes in the pathogenesis of conjunctivochalasis.

AIM: To investigate the pathologic changes in the brain and its underlying mechansims during ischemia-reperfusion of rat hindlimbs.METHODS: SD rats were divided into the normal(N), sham(S), 4 h ischemia without reperfusion(I), and 4 h ischemia-2, 6,12,18 or 24 h reperfusion (I-R) groups at random. Ischemia and ischemia-reperfusion were established with the occlusion or/and re-opening of the terminal of abdominal aorta, respectively. The pathologic changes in the brain tissue were morphologically observed. The expression of inducible nitric oxide synthase ( iNOS ) mRNA, and iNOS protein and the nitrotyrosine, a marker of peroxynitrite (ONOO -),in the brain tissue were detected with RT-PCR and immunohistochemical technique, respectively. The brain superoxide dismutase (SOD) activity and malondialdehyde (MDA) contents were spectraphotometrically measured.RESULTS: Hydropic degeneration and severe injury to neurons were only showed in I-R group. Expressions of iNOS mRNA and protein were demonstrated in I-R, I and S groups, which were maximal in I-R 6 h group. iNOS positive neurons and microglias were more spread in I-R 6 h group than those in S and I groups. NT positive neurons were localized in the cerebral cortex and hippcampus of I-R 6 h group. The contents of MDA markedly increased, while the activity of SOD significantly decreased in I-R 6 h group compared to the N, S and I groups. There were no significant changes in MDA and SOD in N, S and I groups.CONCLUSION: Severe ischemia-reperfusion of rat hindlimbs could induce brain injury, and its mechanisms might be related to enhanced expression of iNOS -NO-ONOO - in the brain.

AIM: To detect the changes of heme oxygenase-1(HO-1) expression in brain following ischemia-reperfusion of hindlimbs in rats and to elucidate their significance. METHODS: Ischemia-reperfusion was established using the occlusion for 4 h and re-opening for 2-24 h of the femoral arteries. The expression of HO-1 mRNA in brain was detected with reverse transcription-polymerase chain reaction (RT-PCR). The expression and location of HO-1 protein were detected with immunohistochemical technique. The observation of pathologic changes of brain was made following the inhibition of HO-1 by zinc protoporphyrin (ZnPP). RESULTS: The relative expression level of HO-1 mRNA significantly increased in I-R group, compared to those in control group. It was maximal in I-R 12 h group, and thereafter expression level of HO-1 mRNA decreased, however significant expression was still detected in I-R 24 h group (P
