AIM: To investigate the effects and safe of low molecular weight heparins (LMWH) in the treatment of patients with chronic pulmonary heart diseases (CPHD) at hypercoagulability state. METHODS: 65 patients were randomly assigned to treatment group (n=33) and control group (n=32). All patients were given routine treatments. The patients of treatment group were hypodermically injected with 4 100～6 150 U of LMWH per day for 7 days as a course. RESULTS: After 7 days of the treatments, the patients of treatment group showed better curative effect and significantly increase in PaO_2 and AT-III and decrease in PaCO_2 and FIB in comparison with the patients in control group (P

AIM: To evaluate the effect of hyaluronate based gel (HAbg) in prevention of pleural thickening and adhesion in patients with tuberculous pleural effusions. METHODS: 52 patients with middle amount of tuberculous thoracic fluid accumulated, fluid bound, and pleura thickened more than 2 mm were divided into two groups at random. The patients of two groups were all given standard treatments with anti tuberculous drugs. HAbg was injected into intra thoracic cavity in treatment group (27 patients), while saline (NS) was introduced into intra thoracic cavity in control group (25 patients). Before and after HAbg injection, thoracic fluid routine and protein quantification were tested respectively. Pulmonary functions were measured after 2 weeks and 3 months of thoracic fluid absorption. RESULTS: Patients treated with HAbg showed significantly thinner pleura, lower proteins and white blood cell count in thoracic fluid, and higher FEV1% and FVC% for their pulmonary function in comparison with the control group. CONCLUSION: Intrathoracic injection of HAbg can prevent pleural thickening and improve the lung function in patients with excess fluid of tuberculous thoracic cavity.

AIM:To investigate whether the protective effect of adiponectin on glucose and lipid metabolism is achieved through down-regulating major histocompatibility complex classⅡ( MHCⅡ) in the adipose tissue.METHODS:Adiponectin knockout ( KO) mice and C57BL/6 ( WT) mice were fed with high-fat diet and standard diet for 24 weeks, re-spectively.The body weight, fasting blood glucose (FBG), fasting insulin (FINS), homeostasis model assessment of insu-lin resistance (HOMA-IR), triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol ( HDL-C) , hepatic histology, and classⅡtrans-activator ( CIITA) , histocompatibility 2 class II antigen E beta (H2-Eb1) and cluster of differentiation 74 (CD74) mRNA and MHC II protein levels in adipose tissue were measured at sacrifice.siRNA targeting MHC II and overexpression vector was used in 3T3-L1 cells to explore the effect of adiponectin on the protein level of MHCⅡ.RESULTS:The levels of body weight, FBG, FINS, HOMA-IR, TC, TG, LDL-C, hepatic steatosis, CIITA, H2-Eb1 and CD74 mRNA expression, and MHCⅡ protein expression in the KO mice were higher than those in the WT mice that fed with high-fat diet or standard diet.In 3T3-L1 cells, inhibition of adiponectin reversed MHC II protein level induced by specific siRNA.The expression of MHC II in adipocytes decreased after adiponectin was overexpressed.CONCLUSION: Adiponectin improves glucose and lipid metabolism through sup-pressing the expression of MHCⅡin the adipose tissue.

Objective To apply Canadian Occupational Performance Measure (COPM) on the patients injured in Sichuan Earthquake. Methods COPM was applied to evaluate 51 patients in hospital before and 1 months after treatment. The first evaluation confirmed the problems on occupational activities for them. Then the plan was made to solve the problems. The second evaluation was to assess the effect of the treatment.Results The problem of self-care activity is more than that of productive activities and leisure activities(P<0.01). Total scores of performance of occupational activity and satisfaction improved(P<0.01, P<0.01)Conclusion COPM is helpful to confirm the problems of occupational activities and contribute to develope the primary goals for rehabilitation and treatment programs.

To investigate the differences of proliferation capacity and phenotype properties of mesenchymal stem cells (MSCs) derived from bone marrow (BM) of aplastic anemia patients, fetuses and children, MSCs were isolated from BM of patients with aplastic anemia and expanded in vitro; MSCs derived from BM of fetuses and children were used as normal control groups, three sources of MSCs were compared by morphology, in vitro proliferation capacity, phenotype and immunocytochemistry. The results showed that MSCs could be isolated and expanded from aplastic anemia patient BM. MSCs derived from BM of aplastic anemia patients shared a similar morphology and phenotype with derived MSCs from BM of fetuses and children. However, in vitro proliferation capacity of MSCs derived from BM of aplastic anemia patients after 20 population doublings (PD) was significantly lower, compared with MSCs from BM of fetuses and children. BM MSCs derived from children and fetuses proliferated for more than 30 PD. It is concluded that BM MSCs from aplastic anemia patients appears to be normal in phenotype but their proliferation capacity is lower in comparison with control groups.
