Objective To study the relationship between serum levels of C reactive protein,adiponectin and severity of disease,joint function in patients with rheumatoid arthritis(RA).Methods A total of 85 cases of RA treated in our hospital from September 2014 to August 2016 were selected into the RA group,and 20 healthy persons were recruited into control group.The serum C reactive protein,adiponectin were detected,compared in the two groups,and to investigate the relationship between them with severity of disease,joint function of the patients.Results C reactive protein of RA patients was(23.63±5.36) pg/mL,which was significant higher than that of the control group,the adiponectin,the ratio of C reactive protein and adiponectin were(4.64±1.74)ng/mL,0.37±0.06 respectively,which were significant lower than those of the control group,the differences were statistically significant(P<0.05).RA patients with more serious joint injury and disease status,the adiponectin,the ratio of adiponectin and C reactive protien were more lower,the C reactive protien was more higher,the differences in different joint injury and disease status groups were significant(P<0.05).Logistic analysis showed that adiponectin(P=0.04),the ratio of adiponectin and C reactive protien(P=0.01) were independent risk factors of bone damage in RA patients.Conclusion Serum C reactive protein and adiponectin level were closely related to the severity of RA and joint function.

Objective To compare 2 kinds of commonly used viral vectors, adeno-associated viral (AAV) vector and lentiviral (LV) vector in the gene transfection for bone marrow derived mesenchymal stem cells (MSCs). Methods MSCs were isolated with density gradient (lymphocytes seperation) and identified with HE staining and immunocytochemistory staining for Nestin. The proliferation of BMSCs was detected with BrdU labeling. AAV mediated gene transfection was carried out through recombinant AAV-LacZ viral particles. For LV mediated gene transfection, the LV particles were used directly. The transfection efficiency was estimated with β-gal staining and green fluorescent protein under the fluorescent microscope respectively. Results MSCs was successfully isolated from the bone marrow. HE staining showed that MSCs was with big nucleus, 1-3 nucleoli, and high nucleocytoplasmic ratio. BrdU labeling suggested that MSCs were proliferating. Some MSCs expressed Nestin. The gene transfection efficiency mediated with AAV vector was 49.1%, and it was 91.4% with LV vector (P<0.01). Conclusion The LV vector is more efficient on gene transfection than AAV vector.

Objective To study the effects of the recipe for activating blood circulation and nourishing qi on expression of mitochondrial ribosomal protein L51 (MRPL51) in CVB3 infection model in rat cardiac myocytes, to reveal the pathogenesis of CVB3 myocarditis in the genetic level, to explore the therapeutic mechanism of the recipe for activating blood circulation and nourishing qi on CVB3 myocarditis, and to confirm the validity of the recipe for activating blood circulation and nourishing qi on CVB3 myocarditis. Methods After establishing CVB3 infection model and treatment model with recipe for activating blood circulation and nourishing qi by culturing neonatal rat myocardial cells, a modified suppression subtractive hybridization (SSH) was used to isolate differentially expressed genes between two model groups. These results were further verified by fluorescence RT-PCR. Results The results of SSH showed that gene expression of the treatment group was lower than that of the CVB3 infection group. The results of fluorescent RT-PCR which agreed with that of SSH displayed the threshold cycle number (Ct) in the treatment group was higher than the virus group. Conclusion Up-regulation of MRPL51 might be one of the pathogenesis of CVB3 myocarditis. The recipe for activating blood circulation and nourishing qi could treat viral myocarditis by regulating the expression of MRPL51.

Objective To investigate the cognition and participation on organ donation in ICU medical staff and analyze the influencing factors, thus to provide reference for the development organ donation promotion measures. Methods 265 ICU medical staff were chosen by convenient sampling method from 10 three-level hospitals in Chongqing and were investigated with a self-designed questionnaire about the cognition, willingness and its influencing factors towards organ donation. Results ICU medical staff′s understanding of brain death, significance, basic conditions and concepts of organ donation were 67.2% (178/265), 61.1% (162/265), 60.0% (159/265), 55.8% (148/265) respectively, but understanding of Principles , registration methods, laws and regulations, and procedures of organ donation were 24.5%(65/265), 12.1%(32/265), 7.9%(21/265), 4.5%(12/265) respectively. 47.5%(126/265) ICU medical staff were willing to donate their own organs, 35.8%(95/265) were consented to relative′s organ donation and 4.5% (12/265) were organ donation applications. 89.1% (236/265) were affected by traditional ethical concepts, 70.2%(186/265) were for the publicity not enough, 51.7%(137/265) did not know about the procedures of organ donation, 37.0%(98/265) were for too much troubled procedures, and 43.8%(116/265) were for the ineffective work of relevant organizations. Conclusions Lacking in-depth understanding of organ donation and low willingness to donate organs in ICU medical staff in Chongqing. Mainly associated with the effect of traditional concept and lack of propaganda to the donation.

Objective:To compare efficacy and time course of adrenocortical function recovery of oral prednisone and intrathyroidal injection of dexamethasone in patients with subacute thyroiditis. Methods: Sixty patients with subacute thyroiditis were divided randomly into 2 groups. Patients in group Dex (30 cases) were treated with intrathyroidal injection of dexamethasone (5 mg,twice per week,and then once per week.). Patients in group Pre (30 cases) were treated with prednisone. Prednisone was orally given in decreasing doses: 30 mg for the first 2 weeks, 20 mg for 2 weeks, thereafter the dose was tapered by 5 mg per week. Clinical outcomes of 2 groups were compared after 2 weeks, 4 weeks,6 weeks and 8 weeks of treatment. Rapid corticotropin stimulation test was used to assess adrenocortical function. A positive response, indicative of normal adrenocortical function,has been defined as a 30 min stimulated cortisol level of more than 552 nmol/L.The initial stimulation test was performed as a baseline study immediately following the diagnosis of subacute thyroiditis,before the initiation of glucocorticoid therapies. The tests were repeated 24 h after completion of glucocorticoid course and 2 weeks and every 4 weeks thereafter until a stimulated cortisol level of more than 552 nmol/L was achieved. Results: Curative rate of group Dex and group Pre after 8 weeks were 100% and 90% respectively. Duration of therapy was (5.7?2.0) weeks in group Dex and (8.8?1.8) weeks in group Pre respectively ( P
