Objective To observe the effect of traditional acupuncture therapy on exercise syndrome.Methods 120 cases were randomly divided into the treating group and control group with 60 cases in each group. The cases in the treating group were treated with acupuncture after exercise, but those in the control group did not receive any treatment. The physical and chemical testing data of two groups before and after exercise were compared.Results After acupuncture treatment, the heart rate, myodynamia, blood glucose, lactic dehydrogenase and creatine phosphate kinase of the cases in the treating group were significantly different from that in the control group ( P<0.01).Conclusion The traditional acupuncture can recover body's balance quickly, and has the effect of resisting exercise fatigue.

The adoption of the system of multi-technical appraisals of malpractice means that the appraisals made each time, which constitute the key basis and evidence for the health administrative departments and the judicial organs to deal with medical disputes, are of legal validity as proof. By analyzing the causes of the differences in the appraisals of certain cases, the authors argue that a correct understanding of the definition of malpractice is the key to a correct determination of it; an appropriate application of the principle of allocating the burden of proof is the key link in the technical appraisal of malpractice; perfection of Regulations on Handling Malpractice, Standards for the Classification of Malpractices, and Temporary Provisions on the Technical Appraisal of Malpractice is the basis of correct and impartial appraisals; and a good grasp of the gist of rules and regulations and appraisal according to law is the guarantee for a correct determination of the nature of malpractices.

Objective To evaluate the neonatal outcomes and the prevalence of congenital malformations in children born after in-vitro fertilization(IVF). Methods IVF children (211 cases) born of 156 mothers from July 1994 to October 2003 and 218 controls were studied. Those controls were randomly chosen from the same hospital matched for the time and season of birth and maternal age. Results The incidence of multi-gestation (37.2% vs 2.3%, OR =24.62, 95% CI : 9.1~72), preterm birth (37.2% vs 8.5%, OR =6.41, 95% CI : 3.5~12.0), cesarean section (97.0% vs 71.8%, OR =14.9,95% CI :5.0~49.5), pregnancy-induced hypetension (22.4% vs 10.8%, OR = 2.39, 95% CI :1.3~4.9), threatened abortion (4.5% vs 0%, OR =3.11,95% CI :2.0~4.8) were significantly higher in the IVF group, but the prevalcnce of fetal distress (14.6% vs 4.5%) was lower comparing with control group( P

Objective_To study the significance of fascin protein expression in ductal intraepithelial neoplasia ( DIN) and invasive ductal carcinoma ( IDC) .Methods_Thirty cases of usual ductal hyperplasia ( UDH) , 30 ca-ses of flat epithelial atypia (FEA,DIN1a), 15 cases of atypical ductal hyperplasia (ADH,DIN1b), 2 cases of DCIS grade1(DIN1c),10 cases of DCIS grade2(DIN2)and 18 cases of DCIS grade3(DIN3)were immunohisto-chemically investigated using monoclonal antifascin antibody and compared with 120 cases of invasive ductal carci-noma (IDC).Results_Fascin protein expression was not found in normal breast tissue, UDH, FEA (DIN1a), ADH(DIN1b),DCIS grade1(DIN1c)and DCIS grade2(DIN2),but only seen in 2 of 18 cases of DCIS grade3 (DIN3)(11.1%), and 18 out of 120 cases of IDC (15%).Fascin protein expression was correlated with ER neg-ative( P<0.05) , PR negative( P<0.05) , tumor grade( P<0.05) and axillary lymph node status( P<0.05) , but not correlated with age,location,tumor sizeand HER2 expression.Conclusions_Fascin protein expression seems to be a late event, usually present in carcinoma.Targetting the fascin pathway may be a noval therapeutic strategy of mammary carcinoma.

Objective To explore extracellular signal-regulated kinase ( ERK1/2 ) expression in the role of curcumin inhibited staurosporine (STS)-mediated neurons toxic injury through added PD098059, and to clarify ERK1/2 mediated inhibitory role of curcumin on STS-induced neurons toxic injury.Methods The neurons toxic injury model of primary cultured hippocampal neurons was established by STS.The experiment was divided into six groups:normal control group, STS model group, PD098059 +STS model group, curcumin +STS pretreatment group, curcumin+PD098059+STS treatment group and curcumin treatment group.The cell viability were determined by MTT method, lactate dehydrogenase (LDH) release rate, cell toxicity were detected, nuclear shape were observed by DAPI staining, and ERK1/2 expression were detected by Western blot method.Results The cell viability of curcumin +STS pretreatment group was significantly higher than STS model group ( P <0.001 ); the cell viability had no significant difference between PD098059 +STS model group and curcumin +PD098059 +STS treatment group;compared with curcumin +STS model group , the cell viability of curcumin +PD098059 +STS treatment group was significantly decreased ( P<0.001 ).LDH results showed that the nerve cell toxicity of curcumin +STS pretreatment group was obviously less than STS model group (P<0.001).The cell nuclear shape showed typical apoptosis morphological characteristics in STS model group, and curcumin inhibited the effect of STS mediated-neuronal apoptosis.ERK1/2 protein expression in curcumin +STS pretreatment group significantly increased compared with STS model group ( P <0.001 ) .Conclusion Curcumin inhibited STS-mediated neurons toxicity injury by up-regulating ERK1/2 expression.After PD098059 blocking the nerve cells ERK1/2 synthesis, the inhibitory action of curcumin failed to implemented, which illustrated that ERK1/2 mediated curcumin to inhibit STS-induced neuronal toxic injury.

Objective The enhanced patterns of atherosclerotic plaque on dynamic contrastenhanced MRI have not been well studied. The aim of this study was to explore the patterns of plaque enhancement and their underlying mechanism by using dynamic contrast-enhanced MRI (DCE-MRI).Methods Atherosclerotic plaques were induced in the aorta of 12 New Zealand White rabbits by a combination of endothelial denudation and high-cholesterol diet. Ten to sixteen weeks after surgery, DCEMRI was performed with a fast spin echo T1 weighted sequence. Thirty-five phases of images were obtained at 71-second intervals. Gd-DTPA was injected coincident with the third scan via marginal ear vein. Specimens were harvested within 12 hours after imaging for HE staining and CD31 immunohistochemical staining which was used to highlight nco-vessels. Plaque enhancement patterns were studied and compared with histological findings. Signal intensity of each plaque section was normalized to pre-contrast signal intensity of psoas muscle, after which signal intensity versus time curve was drawn. Pearson correlation coefficient was used to reveal association between histological neo-vessel count and descriptive parameters derived from signal intensity versus time curve. Results Plaques were significantly enhanced by Gd-DTPA. Enhancement patterns could be described as fast-in and slow-out. Differences in patterns of enhancement were observed between tissues, with fibrous tissue enhanced more than lipid aggregation and leukocyte foci. Peak enhancement( 1. 05 ±0. 30) , initial slope(0. 82 ± 0. 28 ) and area under the curve at early phase(4.97 ± 1.67) derived from signal intensity-time curve had significant correlations with neo-vessel count( 117.7 ± 93. 3) ( r= 0. 553,0. 468, 0. 554 respectively, P ＜ 0. 05 ) . Conclusions The enhanced patterns of atherosclerotic plaque by Gd-DTPA were fast- in and slow-out. Neovascularization, increased endothelial permeability and extracellular matrix may be the reasons for plaque enhancement by Gd-DTPA. DCE-MRI has the potential to quantify the extent of neo-vasculature formation within plaques.

Objective To investigate the clinical features of osteonecrosis of the knee (ONK) in patients with systemic lupus erythematosus (SLE).Methods A retrospective chart review was conducted to identify patients of SLE with ONK.The clinical characteristics of these patients were analyzed.Results Between 2008 and 2013,eighty-one patients with SLE were analyzed in the 210th Hospital of People's Liberation Army.Eleven of these patients were diagnosed as ONK.All of these ONK patients were female.The age of onset ranged from 19-57 (36±13) years.The disease duration ranged from 4.5-31.0 (13±6) years.The local clinical symptom included knee swelling with pain in 5 cases,only pain with no swelling in 1 patient,no symptoms in 5 patients.All patients were with aseptic necrosis of the femoral head.For laboratory examination,7 patients had elevated triglyceride lipids in blood.Three of 7 patients accompanied with cholesterol level increased.Total cumulative dosage of oral corticosteroids was (66 824±27 328) mg.Conclusion ONK in patients of SLE is common and the majority of them have impaired renal function and elevated blood lipids,as well as long-term glucocortico-steroid therapy.
