Objective To investigate the clinical effect of intra-articular injection of sodium hyaluronate combined with psychological intervention in the treatment of knee osteoarthritis.MethodsA total of 90 patients with knee osteoarthritis treated in our hospital from June 2015 to June 2016 were selected as the research object, according to the different treatment methods, the patients were divided into two groups,with 45 cases in each group.The patients in the control group were treated with conventional treatment, while the observation group was treated with conventional therapy and intra-articular injection of sodium hyaluronate.The experimental data of the two groups were compared.ResultsAfter treatment, the changes of knee joint pain score, joint effusion and joint mobility in the observation group is better than those in the control group.The change of knee function score in the observation group was better than that in the control group.The clinical therapeutic effect of the observation group (95.6%) is better than that of the control group (75.6%);There was significant difference between the two groups (P<0.05);There were no serious adverse reactions in the two groups of patients receiving treatment,and there was no significant difference between the two groups.ConclusionThe clinical effect of intra-articular injection of sodium hyaluronate combined with psychological intervention in the treatment of knee osteoarthritis is good, which is worthy of clinical application.

Objective To observe the changes of nitric oxide(NO), nitric oxide synthase(NOS),and endothelin(ET) contents in plasma after acute cerebral infarction(ACI), And to evaluate the therapeutic effect of nimodipine on their changes.Methods 110 cases with ACI were randomly divided into Nimodipine therapeutic group(Nimodipine is used with general therapy,Nimodipine group) and general therapeutic group(general group). NO, NOS and ET contents in plasma at different time after ACI were observed, while control group was set up.Results ET content in plasma after ACI increased significantly until recovery. NO and NOS contents in plasma rise at the beginning, then they declined. ET contents had significant difference between Nimodipine group and general group( P 0.05).Conclusion NO, NOS and ET interfered with the complex process of pathologic after acute cerebral infarction. Nimodipine had therapeutic action on ACI partly depended on affecting content of ET in plasma.

Objective To summarize imaging features of Kallmann syndrome (KS) in children and to improve diagnostic level of the disease.Methods The imaging manifestations of 13 patients with clinically proved KS were retrospectively studied.MRI of rhinencephalon and left wrist X-ray examinations were performed in all the 13 children.Ultrasound of abdomen and pelvis was implemented in the 8 of 13 patients.Results All the patients had abnormalities of olfactory system.Bilateral olfactory bulbs and tracts were absent in 9 patients.Unilateral olfactory bulbs and tracts were absent in 4 patients,in which contralateral olfactory bulbs and tracts were hypoplastic.These patients presented 2 aplastic,17 hypoplastic and 7 normal olfactory sulci.Anterior pituitary was hypoplastic in 3 patients.Bone age showed retardation in 6 of 13 patients.Bilateral testicles were small in all the 8 cases by ultrasound.Conclusions Aplastic or hypoplastic olfactory bulbs and tracts and sulci are seen in children with KS.Anterior pituitary dysplasia is present in part of patients and bone age backward happens in approximate half of the children.

Objective To investigate the correlation between the-1562 C/T polymorphism of matrix metalloproteinase-9 (MMP-9) and the risk of ischemic stroke.Methods All the relevant literatures published were searched from PubMed,Embase,MEDLINE,Web of Science as well as CBMdisc and CNKI before May 2013.After extracting data,a meta-analysis of the studies meeting the requirements was conducted by using Review Manager Version 5.0 and Stata 11.0 software.The effect size was pooled and odds ratio (OR) and 95％ confidence interval (CI) were calculated.Results Six studies were enrolled,including 1115 patients and 979 controls.The ORs after pooled analysis (95％ CIs) were C/T vs.C/C:1.10 (0.71-1.71) and T/T vs.C/C:1.78 (0.89-3.57) of the codominant genetic model,respectively; C/T + T/T vs.C/C:1.13 (0.76-1.67) of the dominant genetic model; T/T vs.C/T + C/C:1.79 (0.90-3.57) of the recessive genetic model,which suggested that there was no significant correlation between the-1562 C/T polymorphism of MMP-9 gene and the risk of ischemic stroke.The analysis of 5 studies in Chinese populations showed that the ORs (95％ CIs) of the above 4 genetic models were 1.24 (0.76-2.04),1.43 (0.52-3.92),1.25 (0.80-1.97),and 1.33 (0.49-3.62),respectively.There were also no significant differences.Conclusions According to the analysis of the available literatures,there was no significant correlation between the-1562 C/T polymorphism of MMP-9 gene and the risk of ischemic stroke.

Objective To observe the effect of electromyographic biofeedback combined with swallowing training on dysphagia after stroke.Methods Ninety-five patients with difficulty in swallowing after stroke were randomly divided into a treatment group (48 eases) and a control group (47 cases).The patients in the treatment group were provided electromyographic biofeedback and swallowing training; the patients in the control group received swallowing training only.The therapeutic effect was assessed with Kubota's drinking water test before treatment and 30d after treatment.Results Swallowing in both groups improved after treatment.The total recovery rate in the treatment group was 87.5％,and in the control group it was 68.0％,a significant difference.Conclusion Electromyographic biofeedback can improve the effectiveness of swallowing training after stroke.

Objective To investigate the presence of type 2 diabetes dyslipidemia,and the association with HDL levels and vascular complications in diabetes.Methods Of 524 cases of type 2 diabetes,fasting blood lipids,blood glucose,glycated hemoglobin results,blood basic data,the level of lipid controlling and based data of the patients were observed.The relevance between abnormal blood lipids and vascular atherosclerosis was analyzed.Results Type 2 diabetic patients have lipid metabolism,in 524 type 2 diabetes patients,58.4％ had lipid disorder;The serum level of HDL in atherosclerosis group[(0.8 ±0.26)mmol/L]was significantly lower than that in non-atherosclerotic group[(0.95 ± 0.43)mmol/L](t =1.648,P ＜ 0.05).Conclusion The decreasing of HDL had relationship to vascular atherosclerosis in patients with type 2 diabetes.

[Abstract ] Objective Evidence from previous studies indicated that over-activation of C3a/C3aR axis existed in the renal tubular epithelial cells of patients with renal diseases including diabetic nephropathy .However , the pathological significance of over-ac-tivating C3a/C3aR axis still remains to be elucidated .In this study, we constructed a renal tubular epithelial cell line over-expressing C3a in a secretory manner in order to provide a cell model to investigate the pathological significance of over -activating C3a/C3aR axis under various pathological scenes . Methods We designed a synthesized C3a secretory expression unit and cloned it into the multi-clonal site of lentivirus expression vector pLenti 6.3-MCS-IRES2-EGFP.After identification by sequencing , recombinant lentivirus was packaged by using pLenti 6.3-C3a-IRES2-EGFP and packaging plas-mid in 293T cells.Then, the recombinant lentivirus was used to in-fect HK2, a cell line of human renal tubular epithelial cells .After screening in medium with blasticidin , blasticidin resistant cell clones were obtained .Real-time PCR and ELISA method were applied to analyze the expression and secretion of stable transfected cells cloned C3a and identify renal tubular epithelial cell lines with stable over-activating C3a. Results ①C3a secretory expression unit was suc-cessfully synthesized and correctly cloned into the multi-clonal site of pLenti6.3-IRES2-EGFP; ②C3a secrectory expression recombi-nant lentivirus LV-C3a was successfully packaged with a high titer of 5 ×108/mL;③HK2 Cell clones resistant for blasticidin were ob-tained;according to the analysis of Real-time PCR and ELISA, the C3a mRNA level in HK2-C3a cell lines was significantly higher than that of HK2 cells(1.0 ±0.5 vs 1321.0 ±18.0, P<0.01) and the secreted C3a level increased significantly ([0.3 ±0.2]ng/mL vs [249.0 ±37.0] ng/mL, P<0.01). Conclusion The present study successfully constructed C 3a secretory expression vector pLenti6.3-C3a-IRES2-EGFP and C3a over-expression renal tubular epithelial cell line HK 2-C3a, which is very useful in further study of the function and significance of C 3a/C3aR axis not only in renal tubular epithelial cells but also in other cell types .
