Objective To study the effects of rehabilitation(RT)on cardiac function in cerebral infarct (CIF)patients with cardiac insufficiency(CIS).Methods Fifty-nine CIF patients with CIS were randomly divid- ed into a treatment group(T group,n=29)and a control group(n=30),and all patients were treated with routine pharmacotherapy for 2 months.In addition,RT was administrated in the T group at the same time.The grading of the New York Heart Association(NYHA)and the changes in cardiac function associated index were observed in both groups before and after treatment.Results Compared with the control group,NYHA grades,left ventricle ejection fraction(LVEF),the levels of brain natriuretic peptide(BNP)in the blood plasma,and the 6min walking range of the T group patients were all significantly improved after treatment(P＜0.05).Conclusion RT can improve car- diac function in CIF patients with CIS.

Using 16S rDNA clone library method, the bacteria composition of the Organic Matter-decomposing Inoculants A and B were investigated. The results indicated that: Sample A was clustered into 14 taxonomic operational units (OTUs),the dominant communities are Weissella confuse, Bacillus subtilis and Bacillus pumilus, which accounted for 28.6%,30.4% and 23.2%;Sample B was clustered into 43 OTUs,the dominant communities are Lactobacillus buchneri, Lactobacillus farciminis and Lactobacillus acetotolerans, which accounted for 18.03%,18.86% and 13.12%, respectively. The results had much difference from the samples' labels:there were not bacteria in the lable of sample A and only Bacillus pumilus was the same with the lable of sample B.This study showed that 16S rDNA clone library method has nicer application perspectives in analying the bacteria of microbial inoculant and its quality control.

OBJECTIVETo explore clinical effects of internal fixation in treating displaced clavicle fracture combined with coracoid process.

METHODSFrom January 2005 to July 2012, 9 patients with displaced clavicle fracture combined with coracoid process were treated by internal fixation. Among them, there were 6 males and 3 females with an average age of 40.1 (ranged from 20 to 57) years old. According to Eyres classification: 3 cases were type II B, 1 case was type II A, 3 cases were type III B, and 2 cases were type V A. All patients had history of injury, and diagnosed as coracoid fracture X-ray and CT before operation. Herscovici criteria was used to evaluate function of shoulders joint after operation.

RESULTSSeven of 9 patients were followed up from 6 to 18 (averaged 11) months. The incisions were healed at stage I, coracoid process obtained bony healing, and reduction of acromioclavicular joint well. According to Herscovici criteria, 6 patients got excellent results and 1 in good.

CONCLUSIONInternal fixation for the treatment of displaced clavicle fracture combined with coracoid process could restore physiological anatomical position of coracoid process, and benefit for recovery of limb function.

The M and NP genes of H5N1 avian influenza virus (A/chicken/Hubei/489/2004) were amplified by RT-PCR from viral RNA,and cloned into pMD 18-T vector respectively.The expression plasmid containing the M gene (pHM6-m) or the NP gene (pHM6-np) was then constructed by inserting the M or NP gene into the pHM6 eukaryote expression vector; the constructed plasmid was then sequenced.32 BALB/c mice (6-week-old) were divided into four groups at random.Three groups of BALB/c mice were inoculated one time the intramuscular route with either 30 μg of plasmid pHM6-m,30 μg of plasmid pHM6-np or the mixture of plasmid pHM6-m (15 μg ) and pHM6-np(15 μg) respectively.A additional group of mice were injected with 100 μ1 PBS as controls.Two weeks later,all mice were challenged with homologous H5N1 avian influenza virus,and observed in the following 12 days.The survival rates of mice in the pHM6-m group,the pHM6-np group and mixed plasmids group were 62.5% ,25.0% and 50.0%,respectively.Results showed that effective protection could be provided by either pHM6-m or pHM6-np,but pHM6-m provided a better protective effect than pHM6-np.

Objective To investigate the expressions and significances of GATA-3 and Th2 cytokines in asthmatic mice.Methods Sixteen BALB/c mice were randomly divided into control group and asthmatic group.The pathological changes in trachial and pulmonary tissue were observed with HE staining method.The GATA-3 mRNA expression in pulmonary tissue was messured with reverse transcription polymerase chain reaction(RT-PCR).And the IL-5,IL-13 proteins in pulmonary tissue were detected with enzyme linked immunosorbent assay(ELISA).Results HE staining showed infiltration of a great deal of inflammatory cells around the bronchial wall in asthmatic group,while there was no obvious infiltration in control group;Compared with control group,the expressions of GATA-3 mRNA and IL-5,IL-13 protein in pulmonary tissue increased significantly(Pa

Objective To evaluate the clinical effect of posterior decompression, internal fixation and interlaminar fusion for the treatment of severe osteoporotic vertebral fracture and collapse complicated with spinal canal encroachment. Methods A retrospective study was carried out in 27 cases of severe osteoporotic vertebral fractures complicated with spinal canal encroachment. The patients were treated with posterior decompression, internal fixation and interlaminar fusion during the period from January 1, 2009 to December 31, 2014. All patients were given vertebral pedicle screw fixation after pedicle augmentation with bone cement. The pain scores of visual analogue scale(VAS), Oswestry Disability Index(ODI), Cobb angle , thoracolumbar Cobb angle and the recovery of neurological function(estimated by Frankel grading system) of the patients were compared beforeoperation, one week after operation and at the end of follow-up. The incidences of internal fixation failure, adjacent vertebral fracture and bone cement leakage also were recorded. Results The patients were followed up for an average of 27 months. The spinal canal occupation rate caused by fracture fragment of posterior vertebral wall was 27.41%~63.85%, with an average of(43.24 ± 10.61)%. Postoperative VAS pain scores, ODI, Cobb angle and thoracolumbar Cobb angle were statistically different from those before operation (P < 0.05). The correction rate for Cobb angle and thoracolumbar Cobb angle was (63.31 ± 23.47)%, (61.91 ± 17.54)%respectively. At the end of the follow-up, the correction loss rate for Cobb angle and the thoracolumbar Cobb angle was (15.38 ± 39.92)%, (21.79 ± 32.20)% respectively, the difference being insignificant compared with those one week after operation(P>0.05). In respect of Frankel grading of neurological function at the end of the follow-up, 6 cases were in grade D and 19 cases were in grade E, but the differences were insignificant compared with those before operation (P > 0.05). None of the patients had surgical site infection, screw looseness or breakage, or rod breakage during the follow-up period. There were 8 patients with asymptomatic bone cement leakage after operation. Vertebral compression fractures recurred in 5 patients, of which 2 had adjacent vertebral fractures and 3 had non -adjacent segment. Conclusion The therapy of posterior decompression, internal fixation and interlaminar fusion is effective for the treatment of severe osteoporotic vertebral fracture and collapse complicated with spinal canal encroachment by obviously relieving pain, improving the physiological function of the spine and stabilizing the spine.

Objective To investigate the features and significance of pathologic changes in apoptosis of small bowel allograft during acute rejection in rats. Methods All 24 recipients were equally divided into four groups ; group A: nonoperative control; group B: allograft ; group C: isograft, group D: treatment control. The graft samples were harvested on day 3, 5, 7, 10 after transplantation, and subjected to histologic examination . Mucosal thickness, villous height and crypt depth were measured, and apoptotic cells of intestinal mucosa of grafts on day 3,5 and 7 after transplantation were examined. Results The mucosal structure was normal in group A; The degree of the inflammatory infiltrated cells ,intestinal mucosa cell apoptosis and structural injury of mucosa in group B were significantly severe compared with groups C and D. As the post-transplanted time increased, the number of musocal apoptotic cells and the degree of mucosal structural injury were significantly increased. The degree of mucosal structural injury in group C was milder than in group B. A few infiltrated cells and mild edema of mucosa occurred in group D , but no mucosal structural injury was found. Conclusions Inflammatory cell infiltration, mucosal epithelial cell apoptosis and mucosal structural damage are the main pathologic features of small bowel allograft during acute rejection. Dynamic observation of the pathologic changes and cell apoptosis of small bowel graft is of certain value in the diagnosis of acute rejection of small bowel graft and in assessment of the degree of small bowel injury.

Objective To study the effect of different concentration of 1,25-dihydroxyvitamin D3[1,25(OH)2D3] on cell proliferation,differentiation and the expression of vitamin D receptor (VDR) in mouse MC3T3E1 osteoblast.Methods Osteoblast were cultured in medium with different concentrations of 1,25(OH)2D3.Incubated for 48 h,cell proliferation of osteoblast were examined by MTT reduction assay (mono-nuclear cell direc cytotoxicity assay),the osteocalcin (OC) levels in cell medium were detected by ELISA,and the expression of VDR mRNA and protein were examined by using SYBR Green real-time PCR and Western blot,respectively.Results 1.After incubation with 1,25(OH)2D3 for 48 h,the number of MC3T3E1 osteoblast was significantly less than that in control group(P0.05).3.SYBR Green real-time PCR and Western blot results showed that the expression of VDR mRNA as well as VDR protein of osteoblast in 10-8,10-9 mol/L experimental groups were significantly higher than those in control group (Pa0.05).Conclusions Cell proliferation of mouse osteoblast can be inhibited,while the cell differentiation was promoted by 1,25(OH)2D3.1,25(OH)2D3 up-regulated the expression of VDR in mouse osteoblast,which suggested that the VDR signal pathway may play some role in proliferation and differentiation of osteoblast.
