Background Experimental study showed that heparanase (HPA)is overexpressed in choroidal neovascularization,suggesting that it may play a role in the pathogenesis of angiogenesis.To certify HPA inhibitor suppress the formation and development of new blood vessel has an important significance for the treatment of choroidal neovascularization.Objective The aim of this study was to investigate the effect of HPA inhibitor on the proliferation of human umbilical vein vascular endothelial cell (UVEC) and the expression of HPA.Methods Hunan UVEC was primarily cultured and passaged and the third generation cells were used in the experiment.Phosphomannopentaose sulfate (PI-88) solution,a HPA inhibitor,was prepared with endothelial cell medium and the end concentrations were 400.00,200.00,100.00,50.00,25.00,12.50,6.25 mg/L respectively.The cells were treated with PI-88 solutions for 24,48 and 72 hours.The growth and proliferation of human UVEC were analyzed using MTT colorimetric assay at absorbance 570 nm.The expression of HPA in the cells was detected by immunochemistry in 48 hours after addition of PI-88.Results Cultured human UVEC showed the fusiform and polygon in shape.The A570 values of human CVEC were significantly different among various concentrations of PI-88 groups (F=2.721,P=0.053 ) and different action time (F=9.656,P =0.002).When PI-88 was administered for 24 hours,the A570 values of human UVEC were insignificantly altered in comparison with the one without PI-88 culture group (P>0.05 ).However,in 72 hours after experiment,the A570 values were significantly declined as the PI-88 concentration was >50.00 mg/L ( P<0.05 ).When PI-88 was administered for 48 and 72 hours,the A570 values of human UVEC were significantly higher than those of 24 hours in <50.00 mg/L groups (P<0.01 ),but no statistical differences were seen in >100.00 mg/L groups among various time points (P>0.05 ).HPA was intently expressed in the cytoplasm of human UVEC.However,at 48 hours after addition of >25.00 mg/L PI-88,the HPA expression was obviously weaker.Conclusions PI-88 can suppress the growth and proliferation of human UVEC at the dose-and time-dependent manner by downregulating the expression of HPA in the cells.

ObjectiveTo study the effect of head acupuncture combined with rehabilitation techniques on movement function of upper limbs after stroke.Methods80 patients with stroke were divided randomly into four groups, group 1 for head acupuncture and rehabilitation techniques, group 2 for rehabilitation techniques, group 3 for head acupuncture and group 4 for control. Fugl Meyer Assessment(FMA) and Facility Assessment For Function of Upper Limbs were applied to assess movement function before and after treatment.ResultsThe scores of FMA and Facility Assessment For Function of Upper Limbs rised more significantly in group 1,2, and 3 than group 4 (P<0.01) and group 1 outgo group 2,3 yet(P<0.05).Conclusions Head acupuncture combined with rehabilitation techniques can improve the movement function of upper limbs of the stroke patients.

Objective To explore the relationship between age and refractive predictability of excimer laser in situ keratomileusis (LASIK)for the correction of myopia.Design Retrospective case series.Participants 362 patients(703 eyes)who had performed LASIK.Methods According to the age,patients were divided into four groups(≤30y,31~34y,35~39y and≥40y).Their preoperative and postoperative refractive powers examined with automatic refactor as well as manifest optometry were analysed and followed up from 6 months to 2 years.According to pre-operative refractive power,patietns were divided into low and moderate myopia group(≤-6.00D), high myopia group(-6.25~-12.00D)and super-high myopia group(≥-12.25D).The eyes with refractive power at post-operative 2 years≥-1.00D were regressive eyes.Main Outcome Measures Refractive error before surgery,intended residual refractive power and 3,6, 12, 24 months post-operative refractive powers.Results There were no significant differences between intended residual refractive powers and refractive powers at post-operative 6 month in 3 groups(

OBJECTIVETo study the clinical characteristics and the prognosis of solitary bone plasmacytoma (SBP).
METHODSFrom June 1997 to June 2002, ten SBP patients were treated in our department. Two lesions were in sacrum, two in pelvis, the other six lesions were in proximal femur, femoral diaphyseal, scapula, thoracic vertebra, proximal humus, and rib respectively. The preoperative laboratory tests were normal. Operation was performed on all patients. The pathologic diagnose was plasmacytoma and then they underwent further laboratory examination, urine Bence-Jone protein is positive in 3 patients, serous IgG value was higher than normal in 2 patients, abnormal M protein was found in electrophoresis in 2 patients. All patients received radiotherapy postoperatively.
RESULTSFour patients were excluded, whose follow-up were lessen than ten months, the other six patients's average follow-up is 28.2 months (from 18 to 48 months), one patient who developed multiple myeloma (MM) six months postoperatively received chemotherapy using M2 protocol and died 21 months after operation. The other five patients had disease-free survive and remain solitary bone lesion after the treatment of surgery and radiology.
CONCLUSIONCompared with MM, SBP patients are younger, the therapeutic results and prognosis are better. The main prognostic factors include age, the size of lesion, the axial bone lesion, persistence of myeloma protein after radiotherapy, early diagnosis and treatment, and so on.

BACKGROUND: Total hip replacement in middle-aged patients is challenging regarding restoration and survival,because these patients are more active than old patients.OBJECTIVE: To retrospectively investigate whether a cementless prosthesis could restore hip function,decrease osteolysis,wear,and enhance prosthesis survival in middle-aged patients.METHODS: Clinical and radiological evaluations of patients undergoing single-side total hip replacement with cement and cementless prosthesis were analyzed preoperatively as well as at 6 months,1,4 and 7 years postoperatively.The outcomes of total hip replacement were assessed using Harris hip scores and survival rate.End point was loosening or revision of the femoral component for any reason.RESULTS AND CONCLUSION: Cementless prosthesis had gained better Harris hip scores than that of cement prosthesis group at 6 months,1,4 and 7 years postoperatively(P < 0.05).The survival rate was greater in cementless prosthesis compared with cement prosthesis during 7-year follow-up(P < 0.05).Results have suggested that cementless prosthesis achieves high rate of functional restoration and a low rate of complications in middle-aged patients following total hip replacement.

Objective To evaluate physiologic ability and surgical stress (E-PASS) for predicting postoperative complications in patients undergoing elective colonic surgery. Methods The clinical data of 158 patients with colonic cancer who were admitted to the West China Hospital from August to October, 2009 were retrospectively analyzed. E-PASS was applied to evaluate the surgical risk. Three indexes of the E-PASS system,including preoperative risk score (PRS), surgical stress score (SSS) and comprehensive risk score (CRS) were compared with actual postoperative outcomes. Correlation between PRS, SSS, CRS and postoperative risks was analyzed using multiple linear regression analysis. Results Of the 158 patients, 27( 17.1% ) had postoperative complications, and the predictive value was 19.4% ± 2.0% according to the E-PASS. Dukes stages, physical performance indexes, severe heart disease, severe pneumonia disease, length of operation time were correlated with the incidence of complications (r = 0. 193, 0. 410, 0. 183, 0. 174, 0. 198, P < 0.05). PRS, CRS and SSS had good predictive effect on postoperative risks (r = 0. 299, 0. 349, 0. 183, P < 0. 05 ). Conclusions E-PASS system is a relatively simple, fast and user friendly tool for predicting the risk of short-term postoperative complications.
