Owing to the advanced age,limb hemiplegia,dehydration,and vessel wall injury,stroke may be easy to cause venous thromboembolism (VTE).VTE mainly include deep vein thrombosis (DVT) and pulmonary embolism (PE).DVT refers to abnormal blood clotting in the veins and impedes venous return.The dislodgement of emboli from the vessel wall can form a thrombotic embolism,and cause PE,myocardial infarction,and stroke; it can not only prolong hospitalization,but also increase the mortality.This article reviews the incidence,risk factors,treatment,and prevention of DVT after a stroke.

Objective To explore the distribution and characterization of class 1 integrons in E.coli from healthy feces,and to elucidate the status of gene-cassettes.Methods Routine method was used to isolate E.coli,antibiotics susceptibility was tested by the disk diffusion method;class 1 integron was detected by PCR assay;PCR products were sequenced and analyzed.Results Of 97 samples,76 isolates were identified,and 25 isolates were multiple-drug resistant.The antibiogram was sulfamethoxazole-trimethoprim,ampicillin,streptomycin,tetracycline,erythromycin.14 of 25 isolates carried class 1 integrons,and the size of integrons differed from 1 800 bp(10 strains) to 750 bp(4 strains).The sequenced PCR product demonstrated that the 1 800 bp integron laboured aadA1-dfrA14-orf gene cassette conferred the resistance to sulfamethoxazole-timethoprim,streptomycin and aminoglycoside;the 750 bp integron laboured dfrA14 gene cassette conferred the resistance to sulfamethoxazole-trimethoprim.Conclusion The different kinds of class 1 integrons exist in E.coli from the healthy students,and determine the multiple-resistant antibiotics.

Total 2625 cases of pulmonary sequestration were collected from literatures of Chinese National Knowledge Infrastructure from 1998 to 2008. The age, gender, clinical symptoms, chest CT scan,chest X-ray findings, lesion location, supplying artery, venous reflux, and preoperative misdiagnosis of 2625 cases were retrospectively reviewed. The male: female ratio of all cases was 1.58: 1. The main clinical symptoms of pulmonary sequestration were cough, sputum, fever, hemoptysis and chest pain, but 13.36% patients were asymptomatic. Chest CT scan showed pulmonary massive lesions (49.00%), pulmonary cystic lesions (28.57%), pulmonary cystic-solid lesions ( 11.57% ), and flaky shadows (7.96%). Pulmonary sequestration mainly located in the lower lobe; 66. 43% located in the left posterior basal segments, and 20. 16% located in the right posterior basal segments. Pulmonary sequestrations were divided into three types, intralobar sequestration (83. 84% ), extralobar sequestration ( 16.03% ), and mixed sequestration (0.13% ). The arterial supply was mainly from branches of thoracic aorta (76. 55% ) and abdominal aorta (18.47%). The clinical manifestations of pulmonary sequestration were various, so the preoperative misdiagnosis rate was as high as (59 ± 20) %. We should take full advantage of clinical symptoms, imaging findings and location characteristics to improve the preoperative diagnosis rate.

Helicobacter pylori is able to colonize the human stomach and dwell in the human stomach for decades or for whole lifetime. A number of potential virulence factors contribute to Helicobacter pylori to colonize this unusual niche. Motility is an essential colonization factor based on the fact that nonmotile variants of Helicobacter pylori can't infect gnotobiotic piglets. Motility is not a colonization factor based on rapid loss of motility of Helicobacter pylori in the gastric lumen in vivo. The exact roles of Helicobacter pylori motility are not yet known. The aim of this article is to discuss correlation between colonization and motility of Helicobacter pylori.

Objective To compare the influence of two different managements of relief incision (exposed relaxation therapy or absorbable hemostatic gauze) in infants' palatoplasty. Methods A total of 118 infants with cleft palate between 5- to 8-month-old for the study were randomly divided into two groups: group A was exposed therapy group, and in group B both sides of relief incision were placed absorbable hemostatic gauze. The wound bleeding, body temperature, diet and incidence of fistula were observed and analyzed after operation. Results There was no significant difference between the two groups in postoperative temperature, diet and wound healing (P>0. 05). The postoperative wound bleeding was statistically significant differences between the two groups (P<0. 05). Conclusions Either exposed therapy or placed absorbable hemostatic gauze in relief incision, has minimal systemic and local reactions in the postoperative infant. The advantages of exposed treatment are economic and simple, and less irritant to the wound.

BACKGROUND:Tetramethylpyrazine (TMP) can inhibit the expression of vascular endothelial growth factor (VEGF), but it is uncertain that TMP inhibit the growth and proliferation of HL-60 leukemic cells induced by VEGF.OBJECTIVE:To observe the effect of TMP on the proliferation of HL-60 leukemic cells induced by VEGF.DESIGN:Repetitive measurement and observation.SETTING:School of Medicine, Wuhan University of Science and Technology.MATERIALS:The experiment was carried out in the Molecular Biology Laboratory Center, School of Medicine, Wuhan University of Science and Technology from March to June in 2007. Human leukemic cell line HL-60 cells were purchased from Shanghai Institute of Cell Biology. TMP hydrochloride injection was produced by Wuxi Seventh Pharmaceutical Products Limited (Lot number:011014), protamine sulfate injection was produced by Shanghai First Biochemical Pharmaceuticals (Batch number:010302), and immunohistochemistry kit was purchased from Boster company.METHODS:①Human leukemic cell line HL-60 cells at log phase were used for the experiments. Cells were treated with 100 μg/L VEGF, and then TMP at final concentrations of 1.5, 15, 150 mg/L was added into culture medium. While the cells in medium without TMP were taken as blank control group, and the cells in medium with 20 mg/L protamine as positive control group. Meanwhile cells without treatment of VEGF were served as VEGF control group. After cells were incubated for 48 hours, the growth inhibiting rate of HL-60 cells was detected by MTT assay.②After HL-60 cells were treated with TMP at the final concentrations of 1.5, 15, 150 mg/L for 24 hours, the protein expression of VEGF in HL-60 cells was examined by SP immunohistochemistry.MAIN OUTCOME MEASURES:①Growth inhibiting rate of HL-60 cells.②Protein expression of VEGF.RESULTS:①Growth inhibiting rate of HL-60 cells:After HL-60 cells induced by VEGF were treated with 15 and 150 mg/L TMP, the absorbance value was significantly lower than that in VEGF control group (P < 0.05).②Protein expression of VEGF:After HL-60 cells were treated with TMP for 24 hours, the protein expression of VEGF was down-regulated with increasing TMP concentration in a dependent manner. Significant differences were observed in the protein expression of VEGF between cells treated by TMP and the controls (P < 0.01).CONCLUSION:TMP can inhibit the proliferation of HL-60 cells stimulated by VEGF and down-regulate the expression of VEGF.
