拟应用脂肪间充质干细胞(adipose derived mesenchymal stem cells,ADSCs)干预小型猪自体皮肤移植实验动物模型,观察其对自体皮肤移植愈合过程中的作用效果。对9头小型猪建立自体皮肤移植动物模型,将小型猪随机分为3组:模型组(Model)、磷酸盐缓冲液组(PBS)、脂肪间充质干细胞组(ADSCs)。各组分别于术前,术后7、14、21和28 d,采集血液和皮肤组织样本,并观察、拍照、记录移植皮片和周围组织临床变化情况。通过对移植皮片表观检查、病理组织学检测,血常规以及血清生化检测,移植皮片组织氧化应激、炎症、再生相关指标检测及血流恢复情况,综合评价ADSCs对小型猪自体皮肤移植创口愈合的影响。临床观察发现,术后ADSCs组皮片恢复速度优于其他两组,在术后28 d,ADSCs组基本恢复正常皮肤状态。在氧化应激方面,ADSCs组SOD、GSH含量显著升高(0.01

Background Restylane, a hyaluronic acid gel, has been widely used as a dermal filler in USA and European countries. This study was designed to study the safety and efficacy of Restylane as a non-permanent dermal filler for facial augmentation therapy in China for the correction of nasolabial folds during a follow-up period of 6 months. Methods The study consisted of a screening visit, a baseline visit during which injection with Restylane was given, and follow-up visits after four weeks, three months and six months. The efficacy was subjectively assessed by comparing the treatment results between pre-treatment and post-treatment. Adverse events were analyzed by severity and duration. Results At six months post-baseline, the subjects and the investigators＇ independent assessment score of Wrinkle Severity Rating Scale was decreased. Global Aesthetic Improvement Scale was considered to have improved by over 90% in some cases. Adverse events related to product and injection was reported in 21.5% of the injections. A vast majority of the post-treatment reactions were mild. Conclusions The efficacy of Restylane for nasolabial fold in a Chinese population was excellent. Restylane was well tolerated and no systemic reactions or other safety concerns were raised.

Superhydrophobic surface was prepared on the zinc substrate by chemical solution method via immersing clean pure zinc substrate into a water solution of zinc nitrate hexahydrate[Zn（NO3）2.6H2O] and hexamethylenete- traamine（C6H12N4） at 95 ℃ in water bath for 1.5 h, then modified with 18 alkanethiol. The best resulting surface shows superhydrophobic properties with a water contact angle of about 158° and a low water roll-off angle of around 3°. The prepared samples were characterized by powder X-ray diffraction（XRD）, X-ray photoelectron spectroscopy （XPS）, energy-dispersive X-ray spectroscopy（EDX）, transmission electron microscopy（TEM）, and scanning electron microscopy（SEM）. SEM images of the films show that the resulting surface exhibits flower-shaped micro- and nano-structure. The surfaces of the prepared films were composed of ZnO nanorods which were wurtzite structure. The special flower-like micro- and nano-structure along with the low surface energy leads to the surface superhydro- phobicity.

Background A Chinese family with autosomal dominant central areolar choroidal dystrophy （CACD） was identified. The purpose of this study was to collect the clinical findings from the family and to identify the genetic entity by linkage analysis.Methods Forty-three individuals from 3 generations of the family underwent ophthalmologic examinations, including best-corrected visual acuity, examination of the anterior segments, and inspection of the ocular fundus after pharmacologic mydriasis. Affected family members further underwent color vision test, color fundus photography, fluorescein angiography, automated perimetry, and electroretinography. The family was followed up for 30 months. Peripheral venous blood or buccal swabs were collected from each family member and genomic DNA was extracted. Linkage analysis was performed for candidate genes or loci using microsatellite markers.Results Seven family members in 3 continuous generations were diagnosed as having autosomal dominant CACD. The family showed progressive development of the disease, affecting both male and female. Age of onset of visual disturbances varied between 11 and 50 years. Phenotypic variability among affected individuals was apparent and ranged from relatively normal-appearing fundus with mild parafoveal pigment mottling to geographic atrophy of the macula. Fluorescein angiography showed hyperfluorescent parafoveal changes in early stage or well-demarcated area of chorioretinal atrophy with enhanced visibility of the residual underlying choroidal vessels in the late stage. Peripheral retina and visual fields were normal in affected individuals. Electroretinogram showed normal or mild reduction in the photopic amplitude. Eight candidate genes （STGD4, RCD1, peripherin/RDS, GUCA 1A, RIMS1, UNC119, GUCY2D, and AIPL1） and two genetic loci （4p15.2-16.3, and 17p13） were excluded to be responsible for the disease by linkage analysis.Conclusions The clinical findings Of this Chinese family with CACD sh
