BACKGROUND:Anti-rotation intramedulary nail fixation for proximal femoral fractures replaces the femoral bearing axis, moves towards body axis relative to hip screw and dynamic ankle screw, enhances the anti-fatigue strength at the fracture site, supports the anti-varus and prevents the rotation of the proximal fracture site, and is suitable for the treatment of unstable fracture. OBJECTIVE:To comparatively observe the effects of dynamic hip screw knife system and minimaly invasive spiral blade anti-rotation intramedulary nail in the repair of unstable intertrochanteric fractures. METHODS: A total of 82 cases of unstable intertrochanteric fractures, who were treated in the Department of Orthopedics, First People’s Hospital of Shunde from January 2012 to January 2014, were selected in this study. The patients were equaly and randomly divided into two groups: dynamic hip screw knife system group and minimaly invasive spiral blade anti-rotation intramedulary nail group. Repair index, fracture healing time and the incidence of complications were compared between the two groups. RESULTS AND CONCLUSION:Healing time and repair index were significantly better in the minimaly invasive spiral blade anti-rotation intramedulary nail group than in the dynamic hip screw knife system group (P < 0.05). Complications appeared in five patients from the minimaly invasive spiral blade anti-rotation intramedulary nail group, with the incidence rate of 12%, and in ten patients from the dynamic hip screw knife system group, with the incidence rate of 24%. The incidence of complications was significantly lower in the minimaly invasive spiral blade anti-rotation intramedulary nail group than in the dynamic hip screw knife system group (P < 0.05). These data suggest that for patients with unstable intertrochanteric fracture, minimaly invasive spiral blade anti-rotation intramedulary nail can decrease the incidence of complications, elevate the safety of the repair method, and promote the functional recovery.

Medical translation is not onlya kind of transmission of medical information but also mutual communication in culture. It is absolutely necessary to train medical students for the translation skills of medical English. This paper has exemplified training on how to deal with medical terms,phrases,texts as well as culture when translating,which is of some importance for the education of medical students.

In real life,vague expression is ubiquitous in any nation and any language.Medical English,as a branch of English for Science and Technology ( EST ),is typical in accuracy of word use.However,like other kind of language,it adopts vague expression,too.Vague expression plays an important role in medical practice.In communication of medical practitioners and patients,appropriate vague expression will improve language expression and communication efficiency.In medical English,the vague words that express approximate,presuming,or uncertain meaning are usually used to replace the exact meaning words.The correspondent translation methods such as literal translation,meaning translation,specialization etc can be used according to the different context.

OBJECTIVE: To learn the prevalence of abnormal components of metabolic syndrome in postmenopausal women, and to explore the optimal body composition indices to predict the abnormal components of metabolic syndrome in postmenopausal women. METHODS: A total of 181 participants were recruited from postmenopausal women who came to Beijing Obstetrics and Gynecology Hospital for health examination between July 2006 and August 2007. They were 41-60 years of age, and there were 1-9 years since menopause. Their clinical and biochemical parameters were measured, including body height, body weight, waist circumference, hip circumference, sagittal abdominal diameter, blood pressure, follicle stimulating hormone, luteinizing hormone, estradiol, triglyceride, high density lipoprotein-cholesterol, fasting,plasma glucose, fasting insulin and body fat. The prevalence of the abnormal components of metabolic syndrome in postmenopausal women was investigated. The correlations between body composition indices and the components of metabolic syndrome were analyzed by partial correlation analysis independent of age, years since postmenopause and the level of estradiol. The body composition indices to predict the abnormal components of metabolic syndrome in postmenopausal women were explored. RESULTS: ①The prevalence of central obesity (waist circumference ≥ 80 cm), hypertriglyceridemia (triglyceride ≥1.7 mmol/L), low high density lipoprotein-cholesterol (high density lipopretein-cholesterol < 1.29 mmol/L), hypertension (systolic pressure ≥ 130 mm Hg or diastolic pressure ≥ 85 mm Hg, 1 mm Hg=0.133 kPa) and high fasting glucose (fasting plasma glucose ≥ 5.6 mmol/L)was 48.1%, 31.5%, 16.6%, 38.7% and 50.3%, respectively. ②Through partial correlation analysis, body composition indices (body mass index, waist circumference, waist-hip ratio, sagittal abdominal diameter, and body fat) had a positive correlation with triglyceride, systolic pressure, diastolic pressure and fasting plasma glucose, while a negative correlation with high density lipoprotein-cholesterol, independent of age, years since postmenopause and the level of estradiol.③Body composition indices and critical value of them used to predict the abnormal components of metabolic syndrome in postmenopausal women were as follows: hypertriglyceridemia: body mass index ≥ 24.845 kg/m~2; low high density lipoprotein-cholesterol: sagittal abdominal diameter ≥ 18.85 cm; hypertension: body mass index ≥ 23.33 kg/m~2; high fasting glucose: sagittal abdominal diameter ≥ 18.10 cm or body fat ≥ 36.515%. CONCLUSION: Central obesity and high fasting glucose are the most common metabolic disorders in postmenopausal women. Obesity is an independent risk factor of metabolic syndrome for postmenopausal women. Body composition indices and their critical values to predict the abnormal components of metabolic syndrome in postmenopausal women are found.
