Objective To investigate the efficacy of progressive resistance exercise for improving the lower limb motor function of hemiplegic stroke patients. Methods Eighty-nine hemiplegic patients were randomly divided into a treatment group (n =46) and a control group ( n = 43 ) . Both groups received routine rehabilitation training, while the treatment group also undertook progressive resistance training. The control group received extra quadriceps femoris training. Before and after the treatment, motor function was evaluated with the Fugl-Meyer lower limb assessment, functional ambulation category (FAC) classification and the modified Barthel index (MBI). Results Before intervention, there were no significant differences between the two groups in any of the assessments. Four weeks later, all the assessment scores obtained with the Fugl-Meyer lower limb assessment, FCA classification and MBI in the treatment group were significantly better than those in the control group. Conclusion Progressive resistance training combined with routine rehabilitation treatment can improve motor function in the lower limbs, ambulation and ability in the activities of daily living of hemiplegic patients after stroke.

Objective To investigate the role of bone marrow mesenchymal stem cells (MSCs) transplantation in repairing injured intestinal mucosa of acute pancreatitis.Methods MSCs were harvested and cultured from femurs of male SD rats.Twenty female SD rats were divided into three groups,and serve acute pancratitis (SAP) model was induced by intraperitoneal injection of L-arginine (2 g/kg) twice.Twelve hours after SAP model established,MSC transplantation group (n=8) were injected MSCs (5 × 106 cell/rat) through tail vein for three days,and SAP group (n=6) were injected the same volume of saline through tail vein as control.Control group (n=6) were only injected the same volume of saline without any treatment.All the rats were sacrificed at 72 hours after model established.The small intestinal tissues were taken for HE staining and pathological score,the TNF-α mRNA and IL-1β mRNA expression level in small intestine and pancreas were tested by RT-PCR.Y chromo-some (Sry) gene in pancreatic and intestinal tissue was examined by polymerase chain reaction (PCR).Results The relative expression quantity of TNF-a mRNA and IL-1β mRNA in pancreas was significant higher in SAP group and MSC transplantation group than in control group (7.22 ± 1.99,3.46± 1.75 vs 1.32 ± 1.04 ; 2.71 ± 0.56,1.92 ± 0.28 vs 0.61 ± 0.45 ),the difference was statistically significant (F=18.375,F=22.701; P＜0.05).Compared with SAP group,the expression quantity of TNF-α mRNA and IL-1β mRNA in pancreas was significantly decreased in MSC transplantation group,the difference was statistically significant (P＜0.05).The relative expression quantity of TNF-α mRNA and IL-1β mRNA in small intestine was significantly higher in SAP group and MSC transplantation group than in control group (3.93 ± 1.08,2.13 ± 0.53 vs 0.68 ± 0.42 ; 2.44 ± 1.54,1.02±0.44 vs 0.60±0.14),the difference was statistically significant (F=21.772,F=6.132; P＜0.05).The expression of TNF-αmRNA and IL-1β mRNA in MSC transplantation group was lower than that in SAP group,the difference was statistically significant (P＜0.05).Compared with SAP group,pathological score indicated that small intestine injure was slighter in MSC transplantation group (3.83±0.28 vs 2.83±0.56),the difference was statistically significant (F=12.013,P＜0.05).Sry gene could be detected in the pancreatic and intestinal tissue of MSC transplantation group.Conclusion Allogeneic MSC transplantation group can inhibit Pro-inflammatory cytokines expression in acute pancreatitis,relieve the intestinal mucosa injury and may involve in the intestinal tissue repair.

AIM: To explore the influence of CD47 molecules on the maturation and function of cultured dendritic cells (DCs). METHODS: Monocyte cell-derived DCs were propagated in granulocyte-macrophage colony-stimulating factor (GM-CSF) and lipopolysaccharide (LPS) plus interleukin (IL)-4, in the presence or absence of anti CD47 monoclonal antibodies (anti-CD47 mAbs). Flow cytometry was used to detect the cell surface phenotype. The concentration of IL-12P70 in supernatant was measured by ELISA technique. The antigen-presenting functions of DCs were determined in one-way mixed leukocyte reaction by Brdu-ELISA. Electrophoretic mobility shift assays (EMSA) was used to examine NF-?B activity. RESULTS: The anti-CD47 mAbs markedly suppressed the expression of CD80,CD86,CD83,CD1a,HLA-DR on the surface of DCs (P

Objective To observe the therapeutic effect of electroacupuncture combined with rehabilitation exercises on swallowing function and cerebral perfusion in dysphagic stroke patients.Methods Sixty-two stroke pa- tients with dysphagia were randomly divided into a treatment group(n=32)and a control group(n=30).The treat- ment group received electroacupunture,rehabilitation exercise and conventional medical treatment,while the control group received only rehabilitation exercise and conventional medical treatment.They were treated once a day,6 times a week for 4 weeks.Water drinking test,stethocatharsis scores and swallowing fluorography were used to assess the swallowing function before and after treatment.Single photon emission computed tomography(SPECT)was also em- ployed to observe the status of cerebral perfusion before and after treatment.Results It was shown that the swallo- wing function and cerebral perfusion in the treatment group were significantly better than the control group after treat- ment.The effective rate in the treatment group was 96.88% while that of the control group was 66.67%.Conclu- sion Electroacupuncture combined with rehabilitation exercises is effective in treating the dysphagic stroke patients, and can significantly improve the brain perfusion of these patients.

The DNA fragment RM07 was isolated from halophilic archaea Halobacterium halobium, which can function as promoter not only in halophilic archaea, but also in Escherichia coli as eubacterial promoter. Sequencing analysis indicated that it possessed the typical consensus sequences (-35 and -10) of bacterial gene promoter, which was confirmed by further deletion analysis: With its -35 sequence deleted and -10 sequence left,DNA fragment RM07a nearly cannot initiate transcription;With its both -35 and -10 sequences,RM07b DNA fragment could be active as promoter at a level even higher than RM07. Our research also showed that the promoter function of RM07 fragment in Escherichia coli was under the control of environmental factors,especially its positive correlation with the increasing concentration of sodium chloride. Therefore, RM07 DNA fragment may be potential1 novel promoter source for constructing double-function vectors. It also has special significance in elucidating the issues of the fusing characteristics of archaea and lateral gene transfer between archaea and bacteria.

Objective To histomorphometricly assess changes occurred in the alveolar ridge following different methods of socket preservation and to compare them against natural healing without interventions. Methods The second、 third and fourth mandibular premolars were extracted from six beagles. Six extraction sites in each dog were randomly assigned to three treatments as follows:natural healing (T1), Bio-Oss Collagen (T2) and immediate implant with Bio-Oss (T3). Six month after surgery, the dogs were euthanized and tissue samples were sectioned, fixed and mounted, then were stained with toluidine blue. The histologic studies and morphological measurements were performed by using an optical microscope and a digital image software. Results Reabsorption in the buccal aspect of the alveolar crest of ridge was showed in all groups. With respect to the mean vertical bone loss of the buccal bone plate, T3 is lower than T1 and T2(P<0.001 ), while no significant differences were observed between T1 and T2. With regard to horizontal dimension of the alveolar process , a statistical significance could be found at 3mm and 4mm below the crest of ridge in group T1 and T3(P=0.017, P=0.042), while no statistical differences were found between other groups. Conclusions Both techniques of alveolar ridge preservation were not able to completely preserve the original bone volume after tooth extraction. Immediate implant placement in combination with Bio-Oss seems to have the potential to limit the reabsorption of the alveolar process efficiently , but the bone preserving effect of Bio-Oss Collagen is undesirable.

Objective To improve the method of orthotopic liver transplantation model in mice.Methods On the basis of "Qian SG" mothod,the techniques of perfusion,harvesting,and trimming of donor's liver,as well as the anastomosis of superior and inferior caval veins were improved.Operations were performed in 70 mice with improved technique(experiment group) and in 70 mice with conventional technique(control group),respectively.The operation time in both donors and recipients,and the survival rates of 48h,1 week and 1 month after operation were compared between the two groups.Results The operation time for both donors and recipients and the time of anhepatic phase were 37?2min,45?2min and 16?2min,respectively in experiment group,while they were 45?2min,54?2min and 23?2min,respectively,in control group,so that the average time for each procedure was significantly shorter(P0.05).Conclusions The improved technique may shorten the operation time and raise the survival rate,and is an ideal method for the establishment of orthotopic liver transplantation model in mice.
