Objective To discuss the therapeutic effects and safety of external ultrasound liposuction to adipose tissue of lower extremities and to summarize the operative techniques. Methods According to the requests of 81 patients, external ultrasound liposuction were performed for them on thighs (n=60), and legs (n=21). It was that the volumes of anesthetic drugs and pure fat as well as the variations of body contour between preoperation and one to three months after operation in every area were recorded. Results Fat aspiration volume in thighs was 3673ml per person with the highest 6100ml. The scale of the circumference of thighs decrease (4.65?1.10)cm with the highest 12.5 cm. In legs, fat volume was 650ml per person with the highest 1200ml, scale decrease (3?1.02) cm with the highest 9cm. Patients had less blood loss, less pain and discomfort with even skin appearance and without severe complications. In the course of operation, knowing well the anatomical character of lower extremities, injecting the anesthetic drugs completely, using appropriate ultrasound time, and sucking in uniform layer were all crucial factors to guarantee the success of the operation. Conclusion External ultrasound liposuction is a safe, effective body contour remodeling operation in lower extremities. Skillful operator is a very important element to successful operation.

ObjectiveTo explore the risk factors of obstructive hydrocephalus secondary to intracranial hemorrhage in premature infants.MethodsA total of 304 premature infants were selected who were diagnosed as sever intracranial hemor-rhage (grade III and IV) by cranial bedside ultrasound admitted to our hospital from Jun. 2013 to Sep. 2014. According to wheth-er the obstructive hydrocephalus was followed, all infants were divided into hydrocephalus group (n=59) and non-hydrocephalus group (n=185). The risk factors of obstructive hydrocephalus secondary to intracranial hemorrhage were analyzed and the lateral ventricle size was measured dynamically.ResultsThe univariate analysis showed the factors related with obstructive hydro-cephalus were as follows: gestational age≤32 weeks, birth weight< 1500g, severe asphyxia, cesarean section, RDS, neonatal infection, heart failure, PDA, acidosis, thrombocytopenia, coagulation abnormalities, and intracranial hemorrhage (gradeⅢ orⅣ) (allP<0.05). Multivariate logistic regression analysis showed that acidosis, thrombocytopenia, coagulation abnormalities, gesta-tional age≤ 32 weeks, severe asphyxia, intracranial hemorrhage (gradeⅢ orⅣ) were independent risk factors for obstructive hydrocephalus (OR: 1.76~20.46, allP<0.05). At each time point after birth, the ratio of posterior horn of lateral ventricle was signiifcantly higher in hydrocephalus group than that in non-hydrocephalus group (P<0.05). There were signiifcant differences in the changes of the posterior horn ratio of left or right lateral ventricle with time in hydrocephalus group (P=0.000), increasing at 14 days and reaching the peak at 28 days after birth.ConclusionsThe risk factors for obstructive hydrocephalus secondary to intracranial hemorrhage in neonates are important. Regular and dynamical monitoring of ventricle size by cranial ultrasound is needed in infants with sever intracranial hemorrhage.

Objective:To investigate YKL-40-mediated inflammation in human bronchial epithelial cells and analyzed the soluble factors secreted by bronchial epithelial cells exposed to YKL-40 that were responsible for increasing proliferation and migration of primary normal human bronchial smooth muscle cells (BSMCs).Methods:YKL-40-induced inflammation was assayed in two human bronchial epithelial cells (BEAS-2B cell line and primary human bronchial epithelial cells ,namely HBECs).In addition,we treated BEAS-2B cells and HBECs with YKL-40,and added the conditioned culture media ( YKL-40-BEAS-2B-CM) and ( YKL-40-HBECs-CM) to BSMCs.The proliferation and migration of BSMCs were determined by premixed WST-1 cell proliferation reagent and QCM chemotaxis migration assay ,respectively.Results: Bronchial epithelial cells treated with YKL-40 resulted in a significant increase of IL-8 production,but have no effect about RANTES ,Eotaxin and TNF-α.YKL-40-BEAS-2B-CM and YKL-40-HBECs-CM induced IL-8 was found to further stimulate proliferation and migration of BSMCs ,and the effects were inhibited after neutralizing IL-8.Conclusion:Through investigating the interaction of airway epithelium and smooth muscle ,our findings implicate that YKL-40 may be involved in the inflammation of asthma by induction of IL-8 from epithelium,subsequently contributing to BSMCs proliferation and migration.Moreover, inhibition of IL-8 signaling is a potential therapeutic target for YKL-40-induced inflammation and remodeling of asthma.

BACKGROUND: Injectable artificial bone composite has been reported to consider as a moulding filler of vertebrae at the histology level; however, the therapeutic effect needs to be further studied at the level of axial pressure capacity. OBJECTIVE: To explore the axial pressure capacity of dogs with thoracolumbar fractures treated by injectable artificial bone composite. DESIGN, TIME AND SETTING: A randomized controlled animal experiment was performed at the Animal Laboratory of Shenzhen Longgang Central Hospital from September 2008 to January 2009. MATERIALS: Type I and type II vertebral pedicle screw systems were provided by Tianjin Zhengtian Medical Device Company Limited; injectable artificial bone composite, which was made of coral-hydroxylapatite compound, recombinant human bone morphogenetic protein-2 (Academy of Military Medical Sciences), and 2% chitosan solution (the Second Military Medical University of Chinese PLA and Shanghai Qisheng Biomaterials Institute), was manufactured according to the methods provided by Yin et al. METHODS: A total of 20 1-year-old healthy dogs were randomly divided into treatment and control groups with 10 dogs in each group. The model of those dogs with thoracolumbar fractures was made by imitating falling accidents; thereafter, the dogs in the treatment group were treated with vertebral pedicle screw system internal fixation and vertebroplasty by filling the injured vertebrae with injectable artificial bones. The control group was treated with vertebral pedicle screw system internal fixation alone. MAIN OUTCOME MEASURES: The maximum pressure intensity of injured vertebra, upper and lower vertebra at vertebral body center was detected using micro-computer pressure testing system after three months. RESULTS: The maximum pressure intensity at vertebral body center was not significant differences in the treatment group (100% cases) between injured vertebral body and its neighboring vertebral body, and axial loading was recovered. While that of 60% cases in the control group was significantly different (P
