原发性高血压合并脑梗塞患者血管紧张素Ⅱ-1型受体基因多态性的研究

目的 探讨血管紧张素Ⅱ－1型受体（angiotensin Ⅱ type 1 receptor,AT1R)基因A1166／C多态性与原发性高血压及合并脑梗塞的关系。方法 应用聚合酶链反应－限制性片段长度多态性方法检测70名健康人、72例原发性高血压无合并症患者及70例原发性高血压合并脑梗塞患者的AT1R基因型；生化技术测定血脂水平。结果 原发性高血压无合并症组及合并脑梗塞组的C等位基因频率分别为11．1％和10．7％，均显著高于正常对照组的3．6％（P＜0．05）；而两者之间的C等位基因频率差异无显著性（P＞0．05）；牟发性高血压患者血浆脂蛋白a水平与AT1R基因正相关。结论 提示AT1R基因可能是原发性高血压的重要遗传因素，但与高血压病患者是否易患脑梗塞无关。

Renal replacement therapies in pediatric intensive care patients: Experiences of one center in Turkey

BACKGROUND: Despite constant improvements in caring for critically ill neonates and infants with congenital cardiac disease, sepsis, bone marrow and solid organ transplantation, acute renal failure (ARF) is an important problem in these children. ARF, severe fluid overload and inborn errors of metabolism are some of the indications for acute dialysis in infants and children. METHODS: The authors had retrospectively evaluated the medical records of Pediatric Intensive Care Unit, Ankara University School of Medicine, Ankara, Turkey patients who had required acute renal replacement therapy between the dates of January 2002 to February 2005. RESULTS: Medical records of 332 patients were reviewed. Acute renal replacement therapy was performed in 21 patients (6.3%; mean age, 9.6 +/- 7.4 years). Dialysis modalities were peritoneal dialysis in 15 patients (71.4%; mean age, 3.9 +/- 5.6 years) and hemodialysis in six patients (28.6%; mean age, 12.1 +/- 3.2 years). A total of 90% of patients had severe systemic disease leading to ARF. A total of 95% of patients had multiple organ dysfunction syndrome. The most common cause of ARF was refractory shock. At the beginning of renal replacement therapy, 10 patients were anuric, nine patients had volume overload, seven patients had decompensated metabolic acidosis and nine patients had hypotension. The average dialysis period was 4.7 +/- 6.4 days. Mortality rate was 66.7%. Eight patients recovered from ARF and chronic renal failure had developed in one patient. CONCLUSION: In the Pediatric Intensive Care Unit, ARF is frequently seen together with multiple organ dysfunction syndrome and the mortality rate is high. Both peritoneal dialysis and hemodialysis are important renal replacement treatment modalities in patients with ARF. The age and hemodynamic status of the patients are important when choosing treatment modality; generally peritoneal dialysis is preferred in infants and toddler, while hemodialysis is preferred in older children.

使用Pipeline栓塞器械治疗颅内动脉瘤成功率预测的Meta分析（英文）

OBJECTIVE To conduct meta-regression for the identification of clinically meaningful characteristics that can predict successful treatment of intracranial aneurysms(IAs)with the Pipeline Embolization Device(PED).METHODS Using the keyword"Pipeline Embolization Device"and pre-specified eligibility criteria,we searched PubM ed and EMBASE and identified 105 original research articles(10,813 patients)published or in press(April 6,2011-December 31,2016)focused on safety and/or effectiveness of PED.We constructed meta-regression models to identify predictors of three measures of PED treatment success,specifically rates of aneurysm occlusion,modified Rankin score(mRS)and death.Rates were loge-transformed and the adjusted R2 statistic was reported for each model.RESULTS Aneurysm morphology and type accounted for substantial variation in 1-year aneurysm occlusion rate(14 studies with 689 patients;Radj2=88.91%).By contrast,predictors of 6-months aneurysm occlusion rate(aneurysm location,aneurysm type)(24 studies with 1,321 patients;Radj2=31.67%)and aneurysm occlusion rate at unspecified follow-up time(year of publication,mean duration of angiographic follow-up)(34 studies with 1,663 patients,Radj2=42.82%)accounted for less variability.Few predictors were identified for death rate(number of patients,aneurysm morphology;34 studies with 6,463 patients,Radj2=50.69%)or mRS≤2(year of publication,mean age,aneurysm morphology;14 studies with 556 patients,Radj2=100%).CONCLUSIONS:Few clinically meaningful characteristics appear to be relevant as predictors of the selected measures of PED treatment success.Future studies should attempt to identify additional predictors while focusing on aneurysm morphology as a key predictor of PED outcomes.     

Identification of T lymphocytes in human mixed hemopoietic colonies

The addition of a T-cell growth-promoting medium (PHA-TCM) to culture conditions that support growth of multi-lineage hemopoietic colonies enhances the proliferation of cells with lymphoid morphology within these colonies. These cells were identified as T lymphocytes by their ability to form rosettes with SRBC and their reaction with monoclonal antibodies (OKT3, OKT4) directed against T-cell-specific surface components. They continue to proliferate extensively under the influence of PHA-TCM after transfer of mixed colonies into liquid suspension culture. Supportive evidence for a common progenitor of myeloid and lymphoid cells within single mixed colonies is provided by Y-chromatin body analysis of E-rosette positive and negative cells in colonies grown in cocultures of male and female bone marrow cells.     

Knowledge and attitudes towards emergency contraception of health-care providers in a region with a high birth rate

Objective?To assess the knowledge of, attitude towards and practices of emergency contraception among health-care providers at a university hospital located in a region with a high birth rate.

Methods?The survey was conducted among 214 health-care providers working at a university hospital located in eastern Turkey.

Results?Two hundred participants completed the questionnaire. Of the respondents, 26.0% said that they did not know anything about emergency contraception, while the remaining 74.0% said that they knew about at least one of the methods of emergency contraception. But among these, the knowledge of 38.5% of the participants about emergency contraception was accurate and that of 61.5% was inaccurate. Thirty-four percent of the respondents stated that they had previously required personally to use emergency contraceptive methods. The most commonly used emergency contraceptive methods were oral contraceptives (69.1%) and intrauterine device (14.7%). None of the respondents knew anything about mifepristone and levonorgestrel.

Conclusion?There is a knowledge deficit among health-care providers who play a significant role in the dissemination of the information about emergency contraception.
