Objective:This study aimed to investigate the role of mitochondrial fusion protein 2 (Mfn2) in chronic renal injury caused by cyclosporine A (CSA) and the possible mechanism.Methods:The model of chronic CSA nephropathy was established in rats. The rats were divided into solvent control group, CSA model group and normal control group. Serum creatinine and urinary protein levels were detected. The tubulointerstitial injury was observed by light microscopy. The changes of mitochondrial structure were observed by electron microscope, and the expression of Mfn2 was detected by Western blot.Results:The levels of serum creatinine and urinary protein in CSA model group at 2 and 4 weeks were significantly higher than those in control group and solvent group ( P<0.05). In CSA model group, tubulointerstitial injury was obvious, mitochondria swelling and deformation were found in tubular epithelial cells, and ridge disappeared. Compared with normal control group and solvent control group, the expression of Mfn2 in CSA model group was significantly decreased at 2 and 4 weeks ( P<0.05), and the expression of Mfn2 in CSA model group at 4 weeks was further decreased compared with 2 weeks ( P<0.05). Conclusions:Mfn2 may play an important role in the injury of tubular epithelial cells caused by cyclosporine.

Objective To investigate the effects of different head positions during operation on wake-up time and quality among ankylosing spondylitis (AS) patients with thoracolumbar kyphosis following pedicle subtraction osteotomy (PSO).Methods Sixty patients were included in this study.All of them,treated with intravenous anesthesia,took the bow-prone position.The patients were randomly divided into two groups:the experiment group where the head was elevated by 10° and the control group where the head was not elevated.The two groups were compared in respect of wake-up time and quality of wake-up test.Results The wake-up time in the experiment group was significantly shorter as compared to that of the control group (1 3.7±2.0 min vs.24.2±2.7min,P＜0.05).The wake-up quality was better as well.Conclusion Elevation of the head by 10° can shorten wake-up time and improve the quality of wake-up test during the procedure of PSO for AS patients with thoracolumbar kyphosis.

This article was aimed to evaluate clinical efficacy of the pulmonary rehabilitation health education guidance mode. The CAT assessment tool was used for evaluation of stable chronic obstructive pulmonary disease (COPD) inpatients and outpatients in the Respiratory Department, Affiliated Hospital of Traditional Chinese Medicine of Xinjiang Medical University. A total of 80 stable COPD patients were randomized divided into the treatment group and control group. In the treatment group, stable COPD patients received pulmonary rehabilitation health education guidance. And then the quality of life was evaluated. The results showed that compared with the control group, after 48-week health education intervention, the CAT score and dyspnea index scale score of 40 patients in the treatment group were decreased with significant difference (P < 0.05). It was concluded that the guidance mode of pulmonary rehabilitation health education was conducive to improving the quality of life of pa-tients with COPD, decreasing the dyspnea index score, and improving exercise tolerance in patients to a certain extent. This pattern can be implemented in the optimization of future clinical practice and nursing.

Objective To evaluate clinical effects of integrated traditional Chinese and western medicine therapy for epilepsy after stroke. Methods Literatures about the treatment of epilepsy after stroke with the combination of traditional Chinese medicine and western medicine which come from the database such as CNKI, VIP, WanFang and Pubmed, were studied and all the randomized controlled trials on comparing therapeutic effects of treating epilepsy between combined treatment of TCM and western medicine and western medicine were enrolled. The Cochrane Collaboration's software RevMan 5 was used for meta-analysis. Results 7 articles were included in the study, there is homogeneity among these articles(P>0.05), The fixed effect model was used for the meta analysis. the combined results were OR=5.17, 95%CI(3.02, 8.82), the overall effect of test Z=6.01, P<0.01, the difference between the treatment group and the control groups was significant, that means the overall effect of the combination of traditional Chinese medicine and Western medicine treatment was better than western medicine treatment; Funnel plot graphic displayed asymmetrically, which indicated the literatures publication bias. Conclusion The current data indicate that the curative effect of TCM and west medicine combined treatment is better than pure western medicine therapy for epilepsy after stroke, but as the literature publication bias, clinical studies need more high quality large samples to prove this conclusion.

Objective To evaluate the effects of peptide-based enteral nutrition (PBEN) on inflammatory response and immune function in rats with intestinal mucositis.Methods 48 Sprague-Dawley male rats were randomly divided into 6 groups (all n =8):basal feed group (BFG),PBEN group (PBENG),intact protein enteral nutrition group (IPENG),methotrexate (MTX) + BFG,MTX + PBENG,and MTX + IPENG.The rats in MTX + BFG,MTX + PENG,and MTX + IPENG were intraperitoneal injected with MTX 10 mg/kg on day 0 and day 6 to induce sustained intestinal injury.From day 1,BFG and MTX + BFG were fed with basal feed,PBENG and MTX + PBENG with PBEN,IPENG and MTX + IPENG with IPEN.The daily energy intake of each rat was 1.80 kJ/g body weight.All the rats were sacrificed on day 11.The pathological changes of intestinal tissue were observed with HE staining,the levels of tissue myeloperoxidase (MPO),nitric oxide (NO),inducible nitric oxide synthase (iNOS),the thymus index and spleen gland index of intestinal tissue were measured using colorimetry,and the serum levels of immunoglobulins IgG,IgA,and IgM were determined with enzyme-linked immunosorbent assay.Results There were no significant differences among BFG,PBENG,and IPENG in each index.Serious injury of intestinal mucosa was observed in MTX groups.Significant differences were noted in all indexes between MTX + BFG and BFG (all P ＜0.05).The mucosal damage score (Chiu score) and the level of MPO and iNOS in MTX + PBENG were significantly lower than those in MTX + BFG [2.3 ± 0.69vs.2.96 ± 0.75,P =0.003 ; (2.30 ± 0.42) U/g tissue vs.(2.98 ± 0.23) U/g tissue,P =0.040 ; (0.37 ±0.06) U/mg prot vs.(0.44 ±0.10) U/rag prot,P =0.030] ; the serum levels of IgG and IgA were significantly higher than those in MTX + BFG (P =0.015,P =0.021) ; however,the levels of NO and IgM were not significantly different between the 2 groups (P =0.597,P =0.160).There were no statistically significant differences between MTX + IPENG and MTX + BFG in terms of the indexes (all P ＞ 0.05).Conclusion PBEN can reduce the inflammation response and improve the immune function in intestinal mucositis rat.
