Objective To discuss the effect of correct limb emplacement on the prevention of shoulder pain of patients with cerebral apoplexy. Methods Forty-one patients after cerebral apoplexy with motor dysfunction of upper limbs but with no sensory disability and shoulder pain were randomly divided into the control group (20 cases)and the observation group (21 cases).Both two groups received routine passive activity and massage of limbs.The observation group was given correct limb emplacement based on routine nursing. Then we evaluate the pain of ariticulus humeri when in the full range of anterior flexion movement after two months. Results The incidence of shoulder pain in the control group was 65.0%,which was statistically lower than that of the observation group (19.0%), χ2=8.91,P ＜ 0.01. Conclusion Correct limb emplacement had preventive effect on patients with cerebral apoplexy.

Immunocytochemistry, flowcytometry and nucleic acid in situ hybridization were used to observe the effect of sodium tanshinon Ⅱ-A silate (DS201) on proliferation of pulmonary artery smooth muscle cell (PASMC) induced by hypoxic endothelial cell condition medium (HECCM). The results showed that DS201 could obviously hinder PASMC to enter S phase from G0/G1 phase (P<0.05), and decrease the expression of PCNA and platelet-derived growth factor (PDGF)-A and B chain mRNA in PASMC respectively, (P<0.01). It was suggested that DS201 could probably inhibit the prolifertion of PASMC mediated by HECCM, through down-regulating the expression of PDGF-A and B chain gene.

Objective To observe the effects of chronic levodopa administration on cerebral dopamine transporter in healthy aged SD rats.Methods Twelve healthy aged SD rats was divided into three groups,which was respectively gavaged with high-dose of levodopa (150 mg/kg), low-dose of levodopa (50mg/kg) and NS everyday for four months. After levodopa was stopped for twenty-four hours, 0.2 ml of 99mTc-TRODAT-1 (800 ?Gi) was injected into the rats through vena caudalis. Three hours later, the rats were sacrificed and the wet weight of striatum, cerebral cortex, cerebella and brain stem was weighed. We measured the counts of radiation and calculated the numerical value of ID.Results The activity of ID in striatum was ( 0.764? 0.129) in high-dose group and ( 0.928? 0.145) in low-dose group. Compared with the control group ( 1.562? 0.289), the differences were significant ( P

Antimicrobial usage rate in surgery patients was 97.18% ,combined an-timicrobial usage rate was 59.90% ,the percentage of one drug,two-drug combination and three-drug combination was 40.10% ,47.82% ,and 12.08% respectively. The percentage of antimicrobial use in patients of type Ⅰ,Ⅱ, and Ⅲincision was 97.56% (40/41),96.93% (158/163)and 100.00% (9/9)respectively,combined antimicrobial us-age rate was 30.00% ,67.72% ,and 44.44% respectively.Conclusion The overuse of antimicrobial agents exists in 33 township central hospitals,antimicrobial usage rate,combined usage rate,antimicrobial use density and antimi-crobial prophylaxis in typeⅠincision operations are all high.

Objective To observe the dyskinesias and motor fluctuation in patients with Parkin-son’s disease, and investigate their influential factors. Methods The detail information of dyskinesias and motor fluctuation of 63 patients with Parkinson’s disease were recorded and followed up when the of L-Dopa therapy was carried out, and all patients were assessed by using UPDRS at “on” and “off” stage, Hoehn and Yahr scale, Schwab and England living scale.The data were calculated with SPSS 10.0 statistic software. Results All patients received alone or combined L-Dopa therapy.Among the 63 patients, 11 (17.5%) were experienced dyskinesias, in which 10 show dystonia; and 36 were (57.1%) experienced motor fluctuation, in which 28 developed wearing-off.The mean daily dose of L-dopa and score of UPDRS in “off” stage were positively correlated with dyskinesias.The duration of therapy with L-dopa was positively correlated with motor fluctuation.The controlled release cabidopa/levodopa was in negative correlation. Conclusions The rate of motor fluctuation was approximately equal to the results reported in other countries.The dyskinesias was lower in occurrence and the mean daily dose of L-dopa and the disease severity should be the main influencing factors to the dyskinesias.The duration of therapy with L-dopa should be influencing factor to motor fluctuation.The main subtype of motor complications should be dystonia and wearing-off.

OBJECTIVE: To observe the effects of Astragalus polysaccharides (APS) on the proliferation and differentiation of 3T3-L1 preadipocytes and to elucidate its possible mechanism. METHODS: The proliferation of 3T3-L1 preadipocytes was detected by XTT method. Lipid droplets accumulated in cytoplasm of the differentiated preadipocytes were observed by using red O staining and quantified by colorimetry. The expressions of peroxisome proliferation activated receptor gamma (PPAR gamma) and CAAT/enhancer binding protein (C/EBP alpha) mRNAs and proteins were detected by real-time polymerase chain reaction (RT-PCR) and Western blotting respectively. RESULTS: APS at different concentrations (0.025-0.8 g/L) affected 3T3-L1 preadipocyte proliferation and differentiation dose-dependently. 3T3-L1 preadipocytes treated with 0.4 g/L APS had lots of lipid droplets in the cytoplasma, which were similar to cells treated with rosiglitazone (ROS). APS significantly increased the mRNA and protein expressions of PPAR gamma and C/EBP alpha (P<0.05, P<0.01, compared with the normal control group) in the course of 3T3-LI preadipocyte differentiation. CONCLUSION: APS can promote the proliferation of 3T3-L1 preadipocytes, enhance the accumulation of lipid drops, and increase the terminal differentiation of preadipocytes, which may be associated with its effects in increasing the expressions of PPAR gamma and C/EBP alpha mRNAs and proteins. The study suggests that APS has potential in the treatment of metabolic syndrome.

Bacterial cellulose (BC) is a high-purity nanometer cellulose secreted by some bacteria. Compared with plant cellulose, it possesses an array of unique properties, including high crystallinity, high water content, good bio-compatibility, high mechanical strength and an ultra-fine fiber network. BC is prosperous as a new type of biomedical material, which has medical applications such as wound dressing, artificial skin, artificial blood vessels and tissue engineering scaffolds. There are, however, some problems to be solved on the large-scale application of BC, such as the high cost, low yield, and poor mechanical stability and so on.

Purpose To detect high mobility group protein A2 (HMGA2) expression in breast cancer, and to analyze its relationship with clinicopathological features and the levels of HMGA2 in different molecular subtypes of breast carcinomas. Methods An immu-nohistochemical study was undertaken for measuring the levels of HMGA2 in 58 breast carcinomas. Results ( 1 ) The expression of HMGA2 was 0, 62. 5%, 60. 0%, 100. 0% and 80. 0% in Lum A, Lum B, HER-2-OE, basal-like breast carcinoma (BLBC) and un-classification phenotype respectively ( triple negative breast cancer, 92. 3%) . High expression of HMGA2 was associated with the tri-ple-negative breast cancer (TNBC) subtypes (P<0. 01). (2) An association was identified between high expression of HMGA2, and high tumor grade, lymph node metastasis (P<0. 05), positive Ki-67, CK5/6 and EGFR (P<0. 05), negative ER and PR (P<0. 01), but no association was observed for tumor size and patients’age. Conclusion An association is identified between high ex-pression, and high tumor grade, lymph node metastasis, positive Ki-67, EGFR and CK5/6, negative ER and PR, that means a high expression of HMGA2 is associated with an adverse outcome in breast cancer. High expression of HMGA2 are associated with the TNBC subtypes. Thus recognizing HMGA2 as a rational target in TNBC. The results of the study have implications for therapeutic target iden-tification and the design of future clinical trials for TNBC.

Objective To investigate the clinicopathological features of human immunodeficiency virus (HIV) negative plasmablastic lymphoma (PBL) with no-immunosuppression,so as to accelerate the understanding for this group of disease.Methods The histological features of 6 HIV-PBL patients with no-immunodeficiency were retrospectively analyzed.Epstein-Barr virus (EBV) status was detected by in situ hybridization.Then,immunohistochemistry and fluorescence in situ hybridization (FISH) method were used to determine the immunophenotype,latent status of EBV and MYC translocation in PBL,respectively.Results HIV-PBL showed monotonous proliferation of plasmablastoid or immunoblast-like cells.Giant cells and necrosis could be observed,with less reactive cells in the background and higher mitoses.All the cases had EBV infection and type Ⅰ latency status of EBV (LMP1-/EBNA2-),and expressed terminal B-cell differentiation immunophenotype (CD20-/CD3-/CD138+/Kappa or Lambda+).Six HIV-PBL patients were elderly (median age was 69.5 years old),had equal incidence of PBL between male and female and showed high frequency of involvement of extranodal and extraoral lesion sites (6 cases and 5 cases,respectively).Median sutvival was 25.5 months.In addition,3 HIV-PBL patients had IGH/MYC translocations.Conclusions HIV-PBL is a new entity with unique clinical features including no-HIV infection,elderly,EBV positivity,and more involvement in extranodal and extraoral sites.HIV-PBL should be distinguished from HIV+ PBL.
