BACKGROUND: Physical therapy is an effective treatment for movement disorder caused by central nerve system injury, while incorrect rehabilitative method will exacerbate the movement disorders in patients.OBJECTIVE: To investigate the effect of physical therapy on movement and daily activity of the patients suffering from brain injury.DESIGN: Randomized controlled study based on patients with a confirmativediagnosis.SETTING: Rehabilitation department in a university hospital.PARTICIPANTS: From September 2001 to August 2002, 78 patients hospitalized in the Rehabilitation Department of the Hospital Affiliated to Luzhou Medical College, with hemiplegia caused by brain injury, were selected into this study. The patients with severe brain injury, severe understanding disability, and severe heart diseases, lung diseases and kidney diseases were excluded.METHODS: The eligible patients were divided into two groups: the physical therapy group(48 patients) and the control group(30 patients) . All the patients in these two groups received medication and the hyperbaric oxygen therapy (HBOT), while the patients in the physical therapy group received an extra physical therapy.MAIN OUTCOMES MEASURES: A Fugl-Meyer assessment(FMA) and a modified barthel index(MBI) were adopted to evaluate the pre-and post-treatment statuses of the patients in these two groups.RESULTS: No significant difference in age, sex and disease course between the physical therapy group and the control group was found. In the physical therapy group, the FMA scale before and after the therapy were 40.43 ± 21.78 and 68.35 ±23.39, and the corresponding MBI scale were 32.82 ± 17.40 and 78.84 ± 25.31 respectively. In the control group,meanwhile, the FMA scales were 41.71 ± 19. 13 and 51.48 ± 22.58, and the MBI scales were 33.02 ± 12.48 and 56.65 ± 26.53. Before the therapy,comparison of FMA and MBI between the two groups showed no significant difference. While after the therapy, significant difference of FMA and MBI between the two groups could be confirmed( t = 2. 14, 2.21, P ＜ 0.05).CONCLUSION: Physical therapy could apparently enhance the rehabilitation of movement ability in patients with brain injury.

Objective To analyse the clinical usage of Shenmai injection, promote the rational use of Shenmai injection. Methods 400 hospital medical records that used Shenmai injection in 2015 were collected and reviewed from hospital information system (HIS) by retrospective analysis method, aggregated and evaluated data by EXCEL. Results In 400 cases, 11 clinical departments used the Shenmai injection, mainly in cardiology of 347 cases(86.75%).The percentage of the non-standard clinical application of Shenmai injection was 84 cases (21.00%). The non-standardized rates of solvent dispensing was 287 cases (71.75%), and the specification incompatibility accounted for 105 cases (26.25%). There was no adverse drug reaction of Shenmai injection. Conclusion The clinical use of Shenmai injection is not yet standardized, which suggests that drugs should be strictly used in accordance with the instruction, in order to avoid risks of off-label use.

Objective Published literatures on the relationship between IL-13 gene polymorphism and the susceptibility of children to bronchial asthma in China were comprehensively analyzed with the use of Meta-analysis to evaluate this relationship.Methods The data were collected from the Medline database,Ovid database,the Cochrane library,and Chinese Biomedical database,and the references of eligible studies were manually screened.Published data related to case-control studies reporting the link between IL-13 polymorphisms and asthma in Chinese children were retrieved through those database.Meta-analysis was conducted to determine whether the IL-13 gene polymorphisms were associated with asthma.Results Eighteen studies were finally accepted for analysis.There were three studies focusing on C-1 112T polymorphism,and six studies focusing on C + 1923T polymorphism,and fourteen studies focusing on G + 2044A polymorphism.There was no evidence to confirm that the genotypes in position IL-13-1112 C/T were associated with asthma in Chinese children [odds ratio(OR) =1.00,95％ CI 0.82-1.22,P =0.98].The OR of asthma for TT/CC genotypes was 1.15 (95 ％ CI 0.57-2.33,P =0.69) and for CT/CC was 1.01 (95 ％ CI 0.82-1.25,P =0.89).There was significant evidence to confirm that the genotypes in position + 1923 C/T were associated with asthma in Chinese children(OR =1.86,95％ CI 1.29-2.67,P =0.000 9).The OR of asthma for TT/CC genotypes was 2.12 (95 ％ CI 1.27-3.56,P =0.004) and for TC/CC was 1.67 (95％ CI 1.18-2.35,P =0.003).There was no correlation between IL-13 + 2044G/A polymorphism and the susceptibility (OR =1.33,95％ CI 0.94-1.88,P =0.11).The OR of asthma for AA/GG genotypes was 1.30 (95 ％ CI 0.76-2.20,P =0.34) and for AG/GG was 1.24(95％ CI 0.90-1.70,P =0.19).Conclusions IL-13 gene + 1923 TT and TC genotypes should be associated with susceptibility of asthma in Chinese children,and the T allele could increase the risk of asthma.No clear relationship was found between the genotype TT/TC at the IL-13-1112 site and the incidence of asthma of children in China,and so was the genotype AA/AG at the IL-13 +2044 site and the incidence.

Objective To compare the effect of intracoronary versus intravenous administration of tiroifban for acute coronary syndrome (ACS) patients during percutaneous coronary intervention (PCI). Methods A search was retrieved from Pubmed, EMbase, Chinese Biomedical Literature Database (CBM), Chinese Journal Full-text Database (CNKI), Chinese Science and Technology Periodical Database (VIP), Cochrane Library to systematically collect the randomized controlled trials of intracoronary versus intravenous administration of tirofiban for the patients with ACS undergoing PCI. The data was extracted from the included studies and analyzed by Cochrane Collaboration's RevMan5.2 software. Results Twenty-five studies involving 2516 patients met the inclusion criteria. The results of meta-analysis showed that thrombolysis in myocardial infarction (TIMI) grade 3 lfow (RR 1.15, 95%CI 1.07-1.23, P=0.0001) were signiifcantly more often achieved in the patients by intracoronary administration of tiroifban (IC group) than those by intravenous strategy (IV group). Left ventricular ejection fraction (LVEF) values in a week after PCI which were evaluated by Cardiac Ultrasound were statistically significant between the two groups (WMD 2.69, 95%CI 0.14-5.25, P=0.04). LVEF values in IC group were increased by an average of 2.69% compared with group IV. Intracoronary administration resulted in a reduced incidence of major adverse cardiovascular events (MACE) at 30-day follow-up (RR 0.51, 95%CI 0.38-0.69, P < 0.0001). However, the incidence of bleeding complications was not statistically signiifcant between the two groups (RR 0.95, 95% CI 0.76-1.19, P=0.64). Conclusions Compared with intravenous strategy, intracoronary administration of tiroifban can be more effective in increasing coronary blood lfow and microvascular perfusion, more signiifcantly in reducing the incidence of MACE at 30-day follow-up and improving the prognosis after PCI without increasing the risk of bleeding.

Objective To assess the in vitro affinity and apoptosis-inducing effect of 131I-K237 peptide (H-His-Thr-Met-Tyr-Tyr-His-His-Tyr-Gln-His-His-Leu-OH) to LNCaP prostate cancer cell line.Methods The K237 peptide was radiolabeled with 131I by the Iodogen method.The radiolabeling efficiency and radiochemical purity after purification were then characterized by TLC in vitro.LNCaP cells were inoculated in 96-well cell plate and divided into following groups (3 duplicate wells for each group):15 kBq 131I-K237was added in the experimental group,different doses of Na131I (5,10,15 kBq) were added in 3 negative control groups,15 kBq 131I-K237 with different doses of unlabeled K237 (1,2,4,8,16 μ g/μl) were added in 3 blocking groups,and PBS was added in blank control group.The cellular binding ratios were calculated after 48 h.LNCaP cells were inoculated in 24-well cell plate and divided into 3 groups:131I-K237group,which including 3 different dose subgroups (5,10,15 kBq) ; unlabeled K237 group,which including 3 different dose subgroups (1,2,4 μg/μl) ; blank control group with 100 μl PBS.All the cells were cultured for 48 h,then optical microscopy (OM) and fluorescence microscopy (FM) were used to observe the cell morphology ; DNA gel electrophoresis was conducted and flow cytometry (FCM) was used to estimate the apoptotic rate of LNCaP cells.One-way analysis of variance and the least significant difference (LSD)-t test were used to analyze the data.Results The labeling efficiency of 131I-K237 was (73.7±3.2) ％ and the radiochemical purity was (96.7±0.6) ％ after purification.The binding ratio of experimental group was (95.8±1.5)％,whereas the ratio of negative groups with 5,10,15 kBq Na131I and PBS group was (8.2±0.4) ％,(8.3±0.6) ％,(8.6±0.5) ％ and 0,respectively.The binding ratio of 131I-K237 and LNCaP significantly declined with the increased dose of unlabeled K237 (t=4.71,P＜0.01).The apoptosis of LNCaP cells cultured with 131I-K237 was observed.Typical DNA ladder was found by DNA gel electrophoresis.The apoptotic rates of 5,10,15 kBq131I-K237 groups were (34.1±2.9)％,(37.3±3.4)％ and (41.7±3.6)％,respectively; whereas those of unlabeled K237 groups and blank control group were (10.8±1.0) ％,(12.5±2.1) ％,(13.1±2.4) ％ and (2.9±0.3) ％,respectively.There were significant differences of apoptotic rate among groups (F=76.31,P＜0.05).The difference among 5,10,15 kBq 131I-K237 groups was statistically significant (t=3.09,3.27,4.52,all P＜0.05).Conclusion 131I-K237 can bind to LNCaP cells with highly affinity and has significant apoptosis-inducing efficacy on the prostate cancer cell line.

Background The pathogenesis of age-related cataract is associated with the apoptosis of lens epithelial cells (LECs) caused by oxidative stress.Previous studies showed that intracellular focal adhesion kinase (FAK) pathway can be activated by H2O2 in vitro,which induced apoptosis of cells.To investigate the effect of oxidative on FAK expression in LECs is one of important studies in the prevention of age-related cataract.Objective This study was to investigate the expression and function of FAK in human LECs treated by H2O2.Methods Human LECs strain (HLECs-B3) were cultured in vitro in the low glucose DMEM with 10％ fetal bovine serum.Different concentrations (0,30,50,70,100,300,500,700,1000 μmol/L) of H2O2 were added into the culture medium for 24 hours.The survival rate of the cells was detected by Cell Counting Kit-8 (CCK-8) assay.Cell morphology as well as the expression and distribution of FAK in the cells were observed by immunofluorescent staining under the laser confocal microscope.Apoptosis was observed by hoechst33258 staining,and Western blot assay was used to quantitatively detect the expression and phosphorylation of FAK.Results The survival rate of the cells was (1.00±0.03) ％,(1.24±0.03)％,(1.36±0.24) ％,(0.93±0.02)％,(1.75±0.19)％,(1.37±0.18) ％,(0.64±0.01)％,(0.59±0.11)％,(0.14±0.05)％ in 0,30,50,70,100,300,500,700,1000 μmol/L H2O2 groups,with a significant difference among them (F =95.30,P =0.00).The survival rates of the cells in the below 300 μmol/L H2O2 groups were significantly higher than those in the 0 μmol/L H2O2 group,and survival rates of the cells in the above 500 μmol/L H2O2 groups were significantly lower than those in the 0 μmol/L H2O2 group(all at P＜0.05).After H2 O2 treatment for 24 hours,HLECs-B3 cells transformed from polygon shape to spindle shape and extended pseudopodiums,meanwhile the green fluorescence for FAK exhibited in the cytoplasm.Cell apoptosis was found in the 1000 μ mol/L H2O2 group.Western blot assay revealed that the expressing levels (grey scale) were significantly different among the various groups (F=28.08,P=0.00),and FAK expressing levels in the below 300 μmol/L H2O2 groups were significantly higher than those of the 0 μmol/L H2O2 group; while the expressing levels in the above 500 μmol/L H2O2 groups were lower than those of the control 0 μmol/L H202 group (all at P＜0.05).After treated by different concentrations of H2O2,the phosphorylation level of intracellular FAK (p-FAK) was significantly higher in 3 hours group than that in 30 minutes group (all at P＜0.05).Conclusions H2 O2 can affect the survival,proliferation and morphology of human LECs by activating the intracellular FAK pathway,indicating that FAK may play roles in the regulation process of cell biological behavior.

AIM To compare the effects of micronised fenofibrate with those of standard fenofibrate on regulating serum lipid. METHODS Wistar rats were fed by the hyperlipids food to induce hypolipidemia, and then orally treated with 20,30,40 mg?kg -1 per day micronised fenofibrate and 20,30,40,60,80 mg?kg -1 per day standard fenofibrate for 10 days. At the tenth day, serum total cholesterol and triglycerides were measured. RESULTS 1 In the same experimental conditions,the minimal efficacious dose of the micronised fenofibrate is 30 mg?kg -1 , but that of the standard fenofibrate is 80 mg?kg -1 ; 2 Using efficacious doses, both kinds of fenofibrate could decrease the content of triglyceride to normal level. They also could decrease the level of total cholesterol by 36 69%～51 56%. CONCLUSION The effects of micronised fenofibrate are better than those of standard fenofibrate, which mainly decreases the level of triglyceride. Micronised fenofibrate also decreases level of serum total cholesterol.
