OBJECTIVE:To compare the clinical efficacy and safety of rivaroxaban and low molecular weight heparin calcium (LMWHA)in the prevention of deep venous thrombosis(DVT)after total hip arthroplasty(THA). METHODS:A total of 100 THA patients selected from orthopedics department of our hospital as research objects were divided into control group and observa-tion group according to random number table,with 50 cases in each group. Control group was treated with LMWHA injection 0.4 mL subcutaneously,qd;observation group was given Rivaroxaban tablet 10 mg orally,qd. Both groups received treatment on the first day after surgery,for consecutive 14 d. Coagulation indexes(PT,APTT,Fib,TT,D-D),VAS score,the incidence of DVT and PE were observed in 2 groups. The postoperative bleeding volume and ADR as hematoma and gastrointestinal bleeding were compared between 2 groups. RESULTS:Before treatment,there was no statistical significance in coagulation indexes or VAS scores between 2 groups(P>0.05). After treatment,PT,APTT,TT and D-D levels,VAS scores of 2 groups were decreased sig-nificantly,while Fib levels were increased significantly;VAS score of observation group was significantly lower than that of con-trol group,with statistical significance(P<0.05). There was no statistical significance in coagulation indexes between 2 groups (P>0.05). The incidence of DVT and PE in observation group were 8.00% and 7.50% ,which were significantly lower than 12.00% and 4.00% of control group,with no statistical significance(P>0.05). The postoperative bleeding volume of observation group was(298.31±52.18)mL,which was significantly lower than(327.40±54.20)mL of control group,with statistical signifi-cance(P<0.05). There was no statistical significance in the incidence of hematoma or gastrointestinal bleeding between 2 groups (P>0.05). CONCLUSIONS:Rivaroxaban and LMWHA can significantly improve coagulation state,prevent the generation of DVT after THA. While rivaroxaban is better in shortening pain time without increasing the risk of ADR.

Objective To prospectively evaluate the safety and therapeutic efficacy ofdalteparin in patients with high risk non-ST-elevation acute coronary syndromes (ACS) during percutaneous coronary intervention (PCI). Methods Atotal of 175 patients with high risk non-ST-elevation ACS were randomly assigned to 2 groups [dalteparin group and unfractionated heparin (UFH) group]. The patients in dalteparin group were given dalteparin at a dose of 5,000U subcutaneously soon after diagnosis and then an additional 60U/ kg intravenous bolus ofdalteparin before emergent PCI. Vascular access sheaths were removed immediately after PCI or coronary artery angiography; the patients in UFH group were given UFH intravenously at a dose of 25mgjust before PCI and an additional 65mg bolus was administered if angiographic findings showed that the patients were suitable for percutaneous transluminai coronary angioplasty (PTCA). Sheaths were removed at 4-6 hours after PCI; Results Eighty-three patients in dalteparin group underwent PCI while 82 patients in UFH group underwent PCI; anti-Xa activities of 52 patients in dalteparin group were measured. The average anti-Xa activity was (0.83±0.26) U/ml at 15 minutes after intravenous injection of dalteparin and anti-Xa>0.5U/ml was obtained in 96.1% of the patients; hematomas at puncture sites were significantly fewer in dalteparin group as compared with UFH group (2.3% vs 9. 2%, P < 0.05); none of the patients in 2 groups suffered major bleeding events. No death, acute arterial reocclusion or emergent revascularization events occurred at 30 days after PCI. Conclusions Our study demonstrated that early subcutaneous injection of dalteparin at a dose 5,000U after diagnosis and an additional 60U/kg intravenous bolus ofdalteparin before PCI is safe and efficacious for patients with high risk non-ST-elevation ACS undergoing emergent PCI

Objective:To study the expression and clinical significance of GPRC5A and SOCS3 in colorectal carcinoma.Methods:SP immunochemical method was performed to detect the expression of GPRCSA and SOCS3 in 45 cases of colorectal carcinoma,25 cases of colorectal adenomas and 22 cases of normal colorectal tissues.Results:1)Expression of GPRC5A in colorectal cancinoma tissue (22.2％) was significantly lower than that in adenomas tissue (52.0％,P＞0.05).The Latter was significantly lower than that in normal colorectal tissue (81.8％,P＜0.05).GPRC5Awas closely related to lymph node metastasis,Duke's stages and the deepness of invasion (P＜0.05).2) Expression of SOCS3 in colorectal cancinoma tissue (24.4％) was significantly lower than that in adenomas tissue (56.0％,P＜0.01).The Latter was significantly lower than that in normal colorectal tissue (86.4％,P＜0.05).SOCS3 was closely related to pathological differentiation,the deepness of invasion,Duke's stages and lymph node metastasis (P＜0.05).3)The expression of GPRC5A was positive correlated with SOCS3 (P＜0.05).Conclusions:The reduced expressions of GPRC5A and SOCS3 may participate in the occurence and development of colorectal carcinorma,suggesting that GPRC5A and SOCS3 may act as biological markers for evaluating the malign degree,prognosis and therapeutic targets of colorectal carcinorma.

Objective To explore the effects of finasteride therapy on the expressions of heat shock protein 70(HSP70)mRNA,heat shock protein 22 (HSP22)mRNA,tumor necrosis factor-alpha (TNF-a),interleukins-1β (IL-1β) in elderly patients with benign prostatic hyperplasia (BPH).Methods Totally 68 elderly men patients with BPH were divided into two groups:regular treatment group (n=34) and finasteride treatment group(n=34),30 elderly men patients without BPH were as control group.The blood samples of patients after treatment were collected for the detections of HSP70mRNA and HSP22mRNA with RT-PCR,meanwhile,the levels of TNF-α,IL-1β were measured by radioimmunoassay (RIA).Effect of treatment was evaluated in accordance with International Prostate Symptom Score (IPSS).Results The expressions of HSP70 mRNA and HSP22 mRNA,TNF-α,IL-1β in BPH patients were higher in finasteride group than in control group (P＜0.01).After 12 weeks therapy,the levels of HSP70mRNA,HSP22mRNA,TNF-α and IL-1β were decreased in finasteride group (P＜0.01 or P＜0.05) but no significantly difference in regular treatment group.Compared with regular treatment group,the expressions of HSP70 mRNA,HSP22mRNA and TNF-α were reduced in the finasteride group after treatment (P＜0.01 or P＜0.05),IPSS was more improved (P＜0.05),but IL-1β was not distingished between two groups (P＞0.05).IPSS was positively related to the levels of HSP70 mRNA,HSP22 mRNA,TNF-α and IL1β (r=0.4251,0.4976,0.4562,0.3627,P＜0.01 or P＜0.05).Conclusions The occurrence and development of BPH are closely related with immunoinflammatory factors.Finasteride not only affects the levels of dihydrotestosterone but also can inhibit the expression of immunoinflammatory factors to improve symptom by reducing the volume of benign prostatic hyperplasia.

In order to investigate the comprehensive quality differences of the seeds harvested in different growing time, and offer theoretical guide for the optimization of seeds' production technology, we analyzed the apparent size, 1 000-grain weight, water absorbency, germination indexes, postharvest embryo rate change, relatively contents of coumarins and the yield of single plant of its seeds of different harvesting time, and compared their comprehensive quality by Topsis analysis. The results showed that there existed obvious differences in yield and quality between seeds of 3 harvesting times. While the harvesting time postponed, the yield of single plant raised, and the shrunken seeds rate decreased, the quality of seedlings increased, while the contents of coumarins showed a steady increase, and the germination rate decreased. The comprehensive quality of the seeds harvested in the black ripe time rank the first place, followed by the brown ripe time and the yellow ripe time. As the harvesting time delays, the seeds' comprehensive quality increases, therefore, we could put off the seeds' harvesting time properly for the high efficient seed production.
