[Objective]To evaluate the effect of integrated management of blood loss in total knee arthroplasty (TKA ) between gypsum fixed up, ice compress,elastic bandage and only with elastic bandage. [Methods]From January 2006 to August 2008,107 patients undergoing TKA were randomized divided into integrated management group( 54 cases) and control group( 53 cases).Sex,age and deseases in two groups were comparative.The patients in integrated management were treated with elastic bandage,gypsum fixed up,leg elevated by 35 degrees at the hip with knee extended, continuous cold therapy.The patient in control group were only treated with single elastic bandage.The loss of blood during 2 h, 12 h, 24 h postoperative were analyzed.[Results]The blood loss was 170 ml(85~505 ml),210 ml(105~560 ml), 260 ml(110~580 ml)at 2 h、12 h、 24 h postoperative in integrated management group,and 180 ml(110~900 ml), 320 ml(115~930 ml),390 ml(170~970 ml) in control group.The blood loss in integrated group was obviously and a statistically significant difference was found between the two groups (P

Objective:To analyze the therapeutic effect and safety of finasteride on aged patients with isolated systolic hypertension (ISH)complicated benign prostatic hyperplasia (BPH).Methods:A total of 84 aged ISH + BPH pa-tients admitted from Jun 2011 to May 2013 were selected.According to medication plan,they were divided into fin-asteride group (n=44)and routine treatment group (n=40,only received routine treatment because they cannot use finasteride).Course of treatment was all six months.International prostate symptom score (IPSS),quality of life (QOL) questionnaire score,prostate-specific antigen (PSA),incidence rate of acute urinary retention,maximum u-rinary flow rate (Qmax),postvoid residual urine (PRV),prostate volume (PV)and incidence rate of adverse reac-tions were compared between two groups.Results:Compared with routine treatment group,there were significant reductions in IPSS [(13.2±2.4)scores vs.(9.4±1.1)scores],PRV [(21.4±4.6)ml vs.(9.0±2.3)ml],PV [(36.8±3.8)ml vs.(29.5±3.0)ml],PSA [(2.45±0.74)μg/L vs.(1.26±0.48)μg/L]and incidence rate of acute urinary retention (17.50% vs.9.09%),P<0.05 or <0.01,and significant increase in Qmax [(10.2±2.4) ml vs.(13.7±3.8)ml]and QOL score [(3.1±1.0)scores vs.(4.7±1.5)scores]in finasteride group (P<0.05). There were no significant difference in incidence rates of adverse reactions between two groups,P>0.05 all.Con-clusion:Therapeutic effect of finasteride is significant and adverse reactions don’ t increase significantly in aged pa-tients with isolated systolic hypertension complicated benign prostatic hyperplasia.

Background and purpose:miR-124 is considered to be a tumor suppressor in multiple tumors, including lung cancer, prostate cancer, bladder cancer, and breast cancer. However, its function is unclear in gastric cancer. This study aimed to explore the expression of miR-124 in human gastric mucosal epithelium cells and different gastric cancer cells, as well as gastric cancer tissues and matched para-cancerous tissues. The correlations of miR-124 expression with gender, age, histological grade, T stage, TNM stage, lymph node metastasis and prognosis of gastric cancer patients were analyzed.Methods:A real-time lfuorescent quantitative polymerase chain reaction (RTFQ-PCR) was employed for detecting the expression of miR-124 in human gastric mucosal epithelium cells and gastric cancer cells. The expression of miR-124 in gastric cancer tissues and matched para-cancerous tissues was detected by in situ hybridization.Results:The RTFQ-PCR results indicated that the expression of miR-124 was down-regulated in MKN-74, MKN-28, MKN-45, MGC-803, SGC-7901 and AGS cells compared to GES-1 cells.In situ hybridization showed that miR-124 was strongly expressed in normal gastric mucosa. However, low expression, focal positive expression or lack of miR-124 expression were observed in gastric cancer tissues. Statistical analysis showed that miR-124 was close-ly correlated to histological stage, TNM stage and node metastasis of gastric cancer patients, but not the age, gender and tumor size. The OS and DFS of the patients with low expression of miR-124 were shorter than that of the patients with high expression of miR-124. Multivariate analysis suggested that miR-124 down-regulation was an independent prog-nostic factor for survival in patients with gastric cancer.Conclusion:miR-124 is down-regulated in gastric cancer cells and tissues. The expression of miR-124 is correlated to histological stage, TNM stage, node metastasis and prognosis.

Objective To observe the effects of ginsenoside Rg1 group on the structure and function of rat skeletal muscle with exercise-induced fatigue.Methods SD rats were randomized into blank control group,model group and ginsenoside Rg1 group.The rats in the model group and ginsenoside Rg1 group received medium-intensity treadmill running to induce exercise-induced fatigue.Ginsenoside Rg1 group was given ginsenoside Rg1 50 mg?kg-1?d-1 for 2 continuous weeks during the modeling.After treatment,malondialdehyde(MDA)content,superoxide dismustase(SOD) activity,mitochondrial membrane potential and free calcium content in the rat skeletal muscle were measured.Meanwhile,ultrastructure of the skeletal muscle was observed under the electron microscope.Results In the model group,SOD activity,mitochondrial membrane potential,and free calcium content were decreased,MDA content was increased,and the difference was significant as compared with the blank control group(P

Objective Study the relationship between HLA antibodies production and the number of Gravidity.Methods A total of 856 pregnant women of first pretanal in Xiasha Hospital of Sir Run Run Shaw Hospital of Zhejiang University from Nov 2016 to Mar 2017 were recruited.The blood samples were collected during 24-28 weeks of pregnancy,and the expression of platelet-specific alloantibody was detected by solid-phase red cell adherence assay.Results There were 67 positive HLA antibody in pregnant women,and the antibody positive rate was 7.8％.There were 15 positive HLA antibody in 334 first pregnant women,14 in 214 two or more pregnancy pregnant women without abortion,10 in 107 pregnant women with once abortion,28 in 223 pregnant women with two or more abortion.The antibody positive rate respectively is 4.5％,6.5％,9.3％ and 12.6％.The production of HLA antibody was significantly associated with the numberof gravidity.Conclusion The antibody positive rate of two or more pregnancy is significantly higher than the fisrt pregnancy.

Objective To explore the effect of neural cell adhesion molecule (NCAM) on adhesion,migration and morphology of mouse bone marrow-derived mesenchymal stem cells (BMSCs).Methods We isolated and cultured BMSCs from wild-type and NCAM gene knockout mice.The expression of NCAM was detected by Western blot and immunofluorescence.Wound healing and adhesion assays were used to detect cell migration and adhesion ability respectively.The morphological changes were observed and the expressings of protein β1 integrin,E-cadherin,β-catenin and N-cadherin were analysed by Western blot.Results The migration and adhesion of BMSCs were significantly reduced after NCAM gene knockout.Meanwhile,the expression of β1 integrin was lower than those in wild-type BMSCs (P<0.01).The morphology of NCAM gene knockout BMSCs changed from irregular to flattened,and expressed epithelial identification marker E-cadherin and β-catenin (P<0.05).However,the expression level of mesenchymal identification marker N-cadherin was decreased (P<0.01).Conclusions NCAM is involved in adhesion and migration of BMSCs via regulating the expression of β1 integrin.Furthermore,NCAMmay negatively regulate the mesenchymal-epithelial transitions of BMSCs.

Objective:To determine the law of dose variation in nasopharyngeal carcinoma patients treated with helical tomotherapy by observing the difference between the actual and planned doses of targets and at-risk organs in these patients. Methods:Ten naso-pharyngeal carcinoma patients were treated with helical tomotherapy. Each single dose distribution and the corresponding computed tomography (CT) images were transmitted to the commercial software MIMvista 6.50, which was used to perform deformable image registration on the CT images. The sum of the actual dose was then obtained by accumulating the single doses. The image-guided actu-al dose was denoted as Plan 2, and the initial plan was called Plan 1. The dose-volume histogram of the dose distribution of targets and at-risk organs in Plans 1 and 2 were compared. Results:The D98 and D95 doses of the planning gross target volume (PGTV) in Plan 2 were significantly lower than those in Plan 1. Compared with Plan 1, the Dmean and D50 doses of double parotids in Plan 2 were higher by 42.23%and 63.82%(P<0.001, P=0.001) on average, respectively, for the left parotid, as well as by 38.64%and 66.76%(P=0.002, 0.004), respectively, for the right parotid. The D2 dose of spinal cord in Plan 2 was significantly higher than that in Plan 1. The doses were higher by 16.49%on average (P=0.026). Conclusion:To achieve precise and individually adaptive radiotherapy, correcting the error between anatomy and placement during tomotherapy for nasopharyngeal carcinoma patients is necessary.

Objective To explore the causes of upper gastrointestinal rebleeding after devascularization operation for portal hypertension and the therapeutic effect of shunt operation.Methods The clinical data of 56 cases of upper gastrointestinal rebleeding after devascularization operation for portal hypertension in our hospital from 1996 to 2006 were retrospectively analyzed.Shunt operation was done in 54 ceses including emergency operation shunt in 5 cases,and elective operation in 49 cases.C-type Mesocaval shunt was done in 45 cases,inferior mesenteric vein-cava shunt in 4 cases,H-type and portacaval in 5 cases.Results Chylorrhea occurred in 13 cases after operation and all recovered;hepatic encephalopathy occurred in 5 cases,and 4 cases recovered,1 died;and 1 case died of liver function failure on the third day after operation.Fifty-two cases were followed-up from 6 months to 9 years,and none had recurrence of upper gastrointestinal bleeding,but 7 died(2 cases died of primary hepatic carcinoma,3 cases died of liver function failure and hepatic encephalopathy,and 2 cases died of non-correlated disease).Conclusions Patients with upper gastrointestinal rebleeding after devascularization operation for portal hypertension should undergo non-operative treatment at first,and elective surgery is done later.If aggressive non-operative treatment for 48h is not successful,then emergency operation should be performed.In elective cases,the operation of first choice is mesocaval interposition synthetic graft shunt,which is particularly applicable in patients with portal vein thrombosis or portal hypertensive gastropathy.

Objective To verify the clinical effect of Qinghuang powder in chronic myelogenous leukemia(CML). Methods 86 CML patients treated with Qinghuang powder, in which 28 cases also partially received herbal medicine (activating blood circulation to dissipate blood stasis). Results 62 cases had complete remission (72.1%), 14 cases partial remission (16.3 %), advance 8 cases(9.3 %), inefficiency 2 cases (2.3 %), and the total efficiency was 97.7 %. The symptom were improved after a week when patients had taken medicines. 44 cases have hepatomegalia, among them 39 cases have diminished or became normal compared to untreated. 70 cases have splenoparectasis, among them 60 cases became normal, 9 cases diminished, and 1 case had no change after treatment. It took 15.5 days in average when spleen began to diminish, and took 62.9 days to become smallest. The WBC began to decrease at 10.4 day and took 54.8 days in average became normal. The major side effect was digestive tract symptom, followed by skin pigmentation and skin excessive cornification. It could be avoided by low dosage. Conclusion Qinghuang powder could not only induce CML to CR, but also improve the clinical symptom of CML and eliminate the infiltration of leukemia cells. It has little influence to Hb and Plt.

Objective: To investigate the clinical efficacy of acupuncture combined with tuina in treating patients with cervical vertigo. ＜br> Methods: According to the principle of randomization, 258 cases with cervical vertigo who met the inclusion criteria for the study were randomly divided into an observation group and a control group, with 129 cases in each. The patients in the observation group received acupuncture combined with tuina therapy, while those in the control group were just treated by the same acupuncture therapy as in the observation group. After 10-day continuous treatments, the clinical efficacies of the two groups were analyzed and compared. ＜br> Results: The total effective rate of the observation group was 100%, versus 86.0% of the control group, and the difference was significant (P＜0.05). After treatment, cervical range of motion (ROM) scores in both groups were statistically significantly different from those before treatment (allP＜0.05); in addition, there was a statistically significant difference in inter-group comparison of ROM score (P＜0.05). ＜br> Conclusion: Compared with simple acupuncture treatment, acupuncture combined with tuina therapy has a better effect in improving the ROM of cervical vertigo patients, with higher clinical efficacy.
