[Objective] To analyze the clinical risk factors for the deep vein thrombosis(DVT)after the total hip arthoplasty(THA).[Methods]Fifty-one THA in 48 patients from February 2007 to July 2007 were evaluated.Color Doppler ultrasonography was used to detect DVT of bilateral lower extremities in all patients before operatioon and at 7 days after operation.Fifteen clinical factors were examined perioperatively in order to analyze their influences on DVT formation after surgery.[Results]Seventeen patients with DVT after operation were discovered through Color Doppler ultrasonic detection,and all of the DVT occurred at the calf intermuscular vein.The incidence of the DVT in all patients was 33.3%,and 41.7% of these DVT patients were asymptomatic.Logistic regression analysis indicated that patients older than 65(OR=116.597),large volume of blood transfusion(OR=1.01)and high level of triglycerides(OR=37.249)were the risk factors for the occurrence of DVT after the THA.[Conclusion]Female,old age,obesity,increase of the level of triglycerides and cholesteral,O blood type,large volume of blood transfusion and patients with diabetes or hypertension raised possibility the occurrence of DVT.Based on this research,it concludes that patients older than 65,large volume of blood transfusion and high level of triglycerides are the risk factors for the occurrence of DVT after the THA,doctors should control the total dose of blood transfusion,to reduce the dose per time and increase the times of massive blood transfusion.Besides these,both clinicians and doctors performing Color Doppler ultrasonography should pay attention to the calf intermuscular DVT.

This article was aimed to study the inhibition of cell proliferation and induction of apoptosis by β-el-emene extract from traditional Chinese medicine (TCM) Rhizoma Zedoariae on human hepatocellular carcinoma (HepG2) cells, as well as the effect on expression of apoptosis-related proteins in liver cancer-burdened H22 mice. Human HepG2 cells were cultured in vitro. MTT method was used in the determination of β-elemene on cell prolif-eration. Apoptosis of cells were detected by the Annexin V-FITC/PI double staining method. Through the establish-ment of liver cancer-burdened H22 mice model, the inhibition of cell proliferation and induction of apoptosis-related protein expression by β-elemene on tumor-burdened mice were observed. The results showed that β-elemene inhib-ited HepG2 cell proliferation, which was dose- and time-dependent. Annexin V-FITC/PI method detected early apoptotic cells. Inhibitions of tumor growth on tumor-burdened mice from different groups were different. Inhibition of tumor growth in the high-dose β-elemene group was relatively low, and that of the middle-dose was more obvi-ous. It was concluded that β-elemene can effectively inhibit human HepG2 cells proliferation. The inhibition on pro-liferation of cancer cells was through the inducing of cell apoptosis. It was also related to the upregulation of apopto-sis-related protein Caspase-3 and downregulation of NF-κB P65.

Objective To investigate the schistosomiasis japonica infection and preventive knowledge of immigration popula-tion in Jinshan District,Shanghai so as to provide the evidence for improving the control work. Methods The immigration popula-tion from schistosomiasis endemic provinces and local people were screened by serum IHA screening for schistosome infection, and the positives were further examined by Kato-Katz technique and the miracidium hatching method. The schistosomiasis preven-tive knowledge and behaviors were investigated by questionnaires. Results A total of 579 were investigated with 348 immigration people and 231 local people,and among them,the male accounted for 72.0%and female accounted for 28.0%. In the immigration population,the main age group was 20-29(56.0%),and 56.6%of the immigration had an education level at senior middle school or higher. The most proportion of immigration was from Anhui Province(36.2%). There were 4 IHA positive persons(1.15%)in the immigration,and 1 was positive in the stool test,and the schistosome infection rate was 0.29%. There were no positives in the local people. The schistosomiasis preventive knowledge of the immigration was generally poor,and some people’s behaviors of see doctor and medication were incorrect. Conclusion There are schistosome infected persons among the immigration population from schistosomiasis endemic provinces,and their schistosomiasis prevention knowledge was poor,thus there is a schistosomiasistransmission risk.

Objective To investigate the role of Wnt/β-Catenin signaling pathway in the endotoxin induced acute lung injury (ALI) during the treatment by mesenchymal stem cells (MSCs).Methods Six SPF male SD rats were isolated and bone marrow mesenchymal stem cells were cultured.A total of 72 SPF male SD rats with 6-week-old were randomly (random number) divided into 4 groups:control group (n =18) in which phosphate buffered solution (PBS) used instead of lipopolysaccharide (LPS);LPS group (n =18) in which LPS used to induce acute lung injury;LPS + MSCs group (n =18) in which MSCs directly transplanted after injection of LPS;Control + MSCs group (n =18) in which MSCs transplanted after injection of PBS.And then 6 rats of each group were sacrificed at 6 h,24 h,and 48 h separately after injection of LPS.At 24 h after the modeling,lung tissue was taken and the levels of Wrnt signaling pathway components were detected by using immunohistochemistry and Western blot.In addition,quantitative realtime PCR was used to detect the expression of Wnt signaling pathway target genes.Results Compare with the PBS control group,significant decrease in lung dry-to-wet ratio and increase in arterial oxygen partial pressure (PaO2) were found in MSCS transplantation groups.According the immunohistological results,Wnt 5a was significantly increased in the LPS-induced ALI rats and decreased after MSCs transplantation.Moreover,decrease in levels of GSK-3β phosphorylation and β-catenin was found in the lung tissue after MSCs transplantation.In addition,the expressions of Wnt signaling target genes Vegf,Axin2 and Klf4 were decreased significantly after MSCs transplantation.Conclusions In the setting of ALI,the therapeutic effect of MSCs was exerted by decreasing the expressions of Wnt 5a,GSK-3β phosphorylation,β-catenin,and Wnt signaling target genes Vegf,Axin2 and Klf4.Wnt signaling implicated in the therapeutic effect of MSC in the setting of ALI.

Objective To evaluate the effects of propofol on apoptosis and invasiveness of human lung cancer cell line A549 cells.Methods Human lung cancer cell line A549 were seeded onto 96-well plates (100 μl/well) and 6-well plates (2 000 μl/well) at a density of 2× 105 cells/ml,and cultured for24 h at 37 ℃ in 5％ CO2.The cells were randomly divided into 2 groups (n =60 each) using a random number table:dimethyl sulfoxide (DMSO) group and propofol group (group P).In group P,propofol with the final concentration of 100 μmoYL was added.In group DMSO,0.5％ DMSO with the final concentration of 0.5％ was added.At 24 h of incubation with drugs,caspase-3 expression was detected by high content screening (HCS); the expression of matrix metalloproteinase (MMP-2) was detected by Western blot analysis.At 0.5,1 and 5 h of incubation,ERK1/2 expression was also measured using Western blot analysis.Results Compared with group DMSO,the expression of caspase-3 was up-regulated,the expression of MMP-2 was down-regulated,ERK1/2 expression was up-regulated at 0.5 of incubation and down-regulated at 1 h of incubation,and no significant change was found in ERK1/2 expression at 5 h of incubation in group P.Conclusion Propofol can promote apoptosis in A549 cells and inhibit invasiveness of human lung cancer cell line A549 cells.

Objective To explore the perioperative efficiency and safety of different regimen of tranexamic acid (TXA) in total knee arthroplasty (TKA).Methods From February 2013 to May 2013,150 female patients with knee osteoarthritis underwent unilateral TKA were randomly divided into three groups,50 cases in each group.Patients received 10 mg/kg TXA by fast intravenous infusion before closing the wound in first group (single dose group),patients in second group received two doses of 10 mg/kg TXA before closing the wound and 3 hours postoperation (repeated dose group),patients in the third group didn't receive TXA (control group).The postoperative blood loss via drainage,the total blood loss,the hidden blood loss,the postoperative hemoglobin concentration at different times and the numher of patients need blood transfusion were recorded.All patients were observed for detecting deep vein thrombosis (DVT) by the color doppler ultrasonography within 5 days postoperation,and the symptomatic DVT and pulmonary embolism (PE) were observed within 90 days postoperation.Results The blood loss via drainage was significantly less in the single dose group (273.6±99.6 ml) and repeated dose group (168.5±80.8 ml) compared with the control group (447.2±101.9 ml),and it was significantly less in the repeated dose group than the single dose group; the total blood loss was significantly less in the single dose group (959.1±291.7 ml) and repeated dose group (818.7±206.9 ml) compared with the control group (1 100.8±288.3 ml),and it was significantly less in the repeated dose group than in the single dose group; there was no differ ences about the hidden blood loss among the three groups.The hemoglobin concentration was significantly higher in the single dose group and repeated dose group than in the control group in day 1,3 and 5 postoperation; and it was significantly higher in the repeated dose group compared with the single dose group.The ratio of transfusion was significantly less in the single and repeated dose groups than in the control group,but no differences exists between the single dose group and repeated dose group.There was no DVT in all of the three groups within 5 days postoperation,and there was no symptomatic DVT and PE in all of the three groups within 90 days.Conclusion 10 mg/kg of TXA infused intravenous before closing the wound is effective and safe in TKA,another dose 3 hours postoperation is much more effective and will not increase the danger of DVT and PE.
