Objective： Dynamic hip screw （DHS） is recommended for the fixation of stable intertrochanteric fractures. Its postoperative cut-out rate ranges from I% to 6%. In osteoporotic bone, normal screws in DHS blade provide less anchorage compared to locking screws. This study aims to compare DHS with locking side plate and conventional side plate. Methods： Fifty consecutive patients with intertrochanteric fractures were randomly allocated for fixation with a standard DHS （group A） and locking DHS （Combi plate, group B）. We compared the clinical and radiological outcomes for the conventional DHS and locking DHS in intertrochanteric fractures. Functional outcome was evaluated using the Parker mobility score. Results： Coxa valga was found more frequently in group A than in group B （12% vs. 0%, P=0.42）. Coxa vara showed the same trend （12% vs. 8%, P=0.81）. Rate of restoration of postoperative neck-shaft angle within 20° of sound side was higher in group B （8% cases） than in group A （4% cases, P=0.98）. The rate of anteversion angle restoration within 10° of sound side was also higher in group B （100% vs. 88%, P=0.85）. The average lag screw slippage in group A and group B was 3.2 mm and 4.2 mm, the average fracture union duration was 17.1 weeks and 16.4 weeks, and the mean Parker score was 5.6 and 5.8 respectively. Screw cut-out was seen in one patient in group A. No cut-out was seen in any of the patient in group B. No patient developed deep infection, avascular necrosis, deep vein thrombosis or any other significant complications. Conclusion： The present study demonstrated that treating intertrochanteric fracture with a locking DHS allows sound bone healing and is not associated with any major complications. Although this report is promising, it should be interpreted with caution because only a prospective study with a large sample size would allow definitive conclusion.

Venous ulceration is the most severe and debilitating outcome of chronic venous insufficiency in the lower limbs and accounts for 80 percent of lower extremity ulcerations. The morbidity caused by them has a serious impact on the quality of life. Sustained venous hypertension, caused by venous insufficiency leads to venous ulceration. The diagnosis is mainly clinical but needs to be differentiated from other causes of lower limb ulcers. Doppler ultrasound is the diagnostic investigation. Treatment options for venous ulcers include conservative management, mechanical treatment, medications, and surgical options. The goals of treatment are to reduce edema, improve ulcer healing, and prevent recurrence. The achievement of good long term results depends on continuous care, ulcer care clinics, home health nursing and regular evaluation by the doctor. They have a crucial role to play for the amelioration of this common and morbid condition.

Introduction: There are a multitude of factors that impact the transmission of HIV from parent to child and the subsequent survival of infected children. Changing dynamics in HIV transmission have led to an increase in the number of children living with HIV in India. This review synthesizes the evidence related to transmission of HIV to children, survival and treatment provision among children living with HIV. Methods: A systematic search was conducted in MEDLINE, IndMed, Web of Science, Google Scholar and major journals related to HIV/AIDS to identify relevant studies published between 1992 and 2015. Inclusion criteria included studies related to parent to child transmission of HIV, treatment of children living with HIV and survival of children living with HIV. One of the authors reviewed the studies and extracted the data in a pre-coded extraction sheet. Results: Thirty-three studies were included in the review. HIV transmission rate from parent to Child who received nevirapine prophylaxis ranged from 2.1% to 27.3%. Extended dose regimen of nevirapine prophylaxis was found to be more effective than the single dose regimen. Adherence to ART ranged from 65% to 95%. Adherence varied depending upon the level of health care facility. Both social and medical factors were associated with non-adherence. CD 4 count at the time of diagnosis and delayed age at HIV diagnosis were important predictors of survival. Conclusion: Shift in policy to provide option B regimen is yielding better results. If the age at diagnosis could be reduced further, it would increase the survival of children living with HIV. The program needs to increase access to the health care facilities.

研苯硼酸衍生物有3种不同构象(syn,syn-;syn,anti-和anti,anti-构象),这3种构象能量非常不同.苯硼酸衍生物通常是采用能量最低的syn,anti-构象存在.然而在配合物中,苯硼酸衍生物展现了硼酸功能团的构象多样性.在本文中,我们采用syn,syn-构象的硼酸衍生物作为结构单元,与含氮给体化合物反应,合成了一系列共晶配合物.采用的含氮给体化合物包括含1,2-重氮片段的化合物(阿普唑仑,1H-四唑,乙酰唑胺和苯并三唑)、邻菲罗啉和2,2′-联吡啶.结果表明,只有1,2-重氮片段不一定能与syn,syn-构象的硼酸及衍生物生成共晶.

Cerebral arteriovenous malformations (AVMs) are a type of vascular anomaly consisting of large intertwined vascular growth (Nidus) that is prone to serious hemorrhaging and can result in patient death if left untreated. Intervention through surgical clipping of feeding and draining vessels to the Nidus is a common treatment. However, identification of which vessels to clip is challenging even to experienced surgeons aided by conventional image guidance systems. The lumped modeling for the Cerebral Arteriovenous Malformation (CAVM) hemodynamic analysis is of high importance in clinical world. As part of the treatment planning for CAVM, it is difficult for doctors to assess the NIDUS part, which may get rupture while inserting catheter. In this paper, we have proposed a non-invasive method for assessing the hemodynamic condition of AVM. The measurement of flow and pressure without intervention along the vessel is a big challenge due to occlusion, bending and thinning of the vessel in Arteriovenous Malformation patients. In this paper, we analyzed a lumped model for the vascular malformation using various imaging multi-modalities that help to analyze CAVM Structures.

密集波分复用(DWDM)的出现扩大了长途传输网的容量,但是DWDM技术的复杂性和使用了昂贵的器件,限制了DWDM在城域网的应用。最新研制的光纤,其在整个宽工作带,包括在(1380±3)nm上都具有低水峰。低水峰光纤与粗波分复用(CWDM)系统比用标准单模光纤(SMF)的同一系统所用的信道间隔宽33%。经过恶劣的环境试验证明,低水峰光纤具有稳定的抗氢气引起的衰减性能,可确保现场安装的低水峰光纤光缆长期可靠地工作。由于低水峰光纤具有优异的弯曲敏感性,使其与最近研制的宽带接入技术,即所谓的光纤到驻地(FTTP)完全相适应。
