Objective To investigate the clinical effect of low molecular weight heparin (LMWH) and pressure pump on perioperative deep vein thrombosis (DVT) in patients with hip fracture and analyze the effect of LMWH on coagulation function. Methods Retrospective analysis of 95 cases hip fractures patients with clinical data, according to the preventive medication of DVT were divided into LMWH group of 42 cases and LMWH joint pressure pump group of 53 cases. The incidence rate of DVT and the degree of limb swelling after operation in two groups were observed. The differences of blood coagulation function indexes, blood rheology and hip function recovery were compared between the two groups. Results The the incidence rate of DVT in combination group was 1.89% (1 cases ), lower than LMWH group of 14.29% (6 cases )(χ2=5.278,P=0.022). After two weeks' treatment, the difference of anterior thigh circumference and calf circumference in combination group was less than LMWH group (P<0.05). The prothrombin time (PT) and activated partial thromboplastin time (APTT) in two groups post-treatment were lower than those pre-treatment, the D-dimer (D-D) was higher than that pre-treatment(P<0.05), but there was no significant difference between two groups. After 3 months' treatment, the Harris functional independence measure (FIM) in combination group was higher than that in LMWH group (P<0.05). Conclusion LMWH combined with pressure pump could significantly reduce the incidence of perioperative DVT in patients with hip fracture, improve the blood coagulation function and hip function.

Objective To explore the HEART risk score in predicting 30-day major adverse cardiovascu-lar events (MACE)for the patients presenting to Emergency Department (ED) with acute chest pain. Methods Patients presented in our ED with acute chest pain were enrolled from January,2016 to April,2016. All cause MACE of each patient were followed up at 30 days by Health insurance information management System and call . Results Total 209 patients were enrolled(mean age 65.28 ± 16.85 years;52.63%male). The age,hypertension, ratio of ACS,SpO2,in-patient number HEART score in MACE subject were significantly higher than that in non MACE patients(P<0.05). The blood pressure at admission of MACE patients was significantly decrease than that in non MACE patients(P<0.05). The MACE within 30 days was 5.74%. The respective areas under the curve (AUC)for 30-day MACE(95% CI)was 0.908(0.846 ~ 0.974). The percent of patients with 30-day MACE with HEART scores between 0% and 3,4 ~ 6,and 7 ~ 10 was 0%,2.5%,and 27%,respectively. Conclusion HEART score can be simple,rapid and accurate prediction of emergency department of patients with acute chest pain within 30 days of MACE,effective elimination of low-risk patients with MACE,it plays a very important role for disease assessment and diagnosis and treatment process in emergency department.

ObjectiveTo investigate the clinical characteristics of the inpatients suffering from dengue fever in order to provide references for better diagnosis and treatment.Methods The clinical data of 158 dengue fever patients admitted to the First Affiliated Hospital of Sun Yat-Sen University from July 23rd to October 31st, 2014 during the 2014 epidemic in Guangzhou area were retrospectively analyzed, including general clinical manifestations, conventional examinations, pathogenesis, and prognosis.Results The mean age of the 158 patients was (56±20) years, with half of them over 60 years old (79 cases). Among them, 94 (59.49%) were male.① The common manifestations included fever (100%), headache (70.89%), myalgia/bone soreness (62.03%), and skin rash (54.43%). Bleeding and plasma leakage were found in 25.95% and 14.56% of the patients respectively.② Laboratory examination:leucopenia (75.32%) and thrombocytopenia (77.85%) were found, and alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were elevated in 57.59% and 77.85% of the patients respectively. However, elevation of blood hematocrit was rare (1.27%).③ It was found that in the acute phase (0 - 5 days of the onset), serum dengue virus antibody IgM (DF-IgM) was positive in 63.54% of the patients (61/96), and 92.62% (113/122) of patients were dengue virus RNA (DENA-RNA) positive.④ The rate of comorbidity in this study was 55.06% (87/158), including hypertension (27.22%) and type 2 diabetes (15.82%), which were the two most common co-morbidities.⑤ All the patients were given supportive therapy to prevent complications. They were also isolated for more than 5 days after onset, and at least for 24 hours after subsidence of fever in addition.⑥ The criteria for the diagnosis of severe dengue were fulfilled in 18 patients (11.39%). One patient died of massive hemorrhage from gastro-intestinal tract, and 1 patient voluntarily left hospital with untreated multiple organ dysfunction syndrome (MODS). Another 2 patients of dengue fever died from primary cardio-cerebrovascular disease, and the remaining 154 patients (97.47%) fully recovered with supportive therapy and complication prevention measures.Conclusions The clinical manifestations of inpatients with dengue fever in this study were typical, and they manifested a higher incidence of severe illness. DENA-RNA could be a sensitive indicator for early pathogenic diagnosis. With symptomatic and supportive therapy, most patients had a good outcome. However, early diagnosis and clinical interventions of severe dengue still need further studies.

Objective To explore the effects of different dose rates of X-ray under the same dose on cell clonogenic formation in non-small-cell lung cancer cell line A549 in order to provide experimental basis for clinical radiotherapy plan. Methods The A549 cells were cultured at low density and irradiated with X-rays at dose of 4 Gy and selected dose rates of 1, 2, 4 and 6 Gy/min, respectively, from a linear accelerator. The 8th day after irradiation, the cells were fixed and stained with Giemsa solution, and colonies containing at least 50 cells were counted. The plating efficiency and surviving fraction were calculated. Results The clonogenic number in non-irradiated cells was 88.6±4.6. The numbers were significantly reduced in irradiated cells at dose rate 1, 2, 4 and 6 Gy/min (12.3±3.4, 9.0±0.8, 5.6±1.0, 11.5±1.7, respectively) than that in non-irradiated control cells (F=678.799, P<0.05). The plating efficiencies were decreased in irradiated cells, especially in 4 Gy/min irradiated cells, which was lower than that in any of the other three dose rate groups (P< 0.05). Conclusions Though at same radiation dose, cancer cells have different clonogenic formation efficiency when irradiation with X-ray at different dose rates. Thus, treatment with optimal dose rate may improve the radiotherapy efficacy.
