Objective To study the method and effect of subcutaneous pedicle flap based on the orbicularis oculi muscle in the treatment of xanthelasma.Methods According to the situation of xanthelasma and the soft tissues of upper eyelid,two new double-folds eyelid was designed.The soft tissues (including the skin and muscle) between two lines were intended to form a subcutaneous pedicle flap based on the orbicularis oculi muscle.Then,after the excision of xanthelasma from the surface of orbicularis oculi muscle,the flap was transferred to the defected site.Finally,a new double-folds eyelid was made.Results 13 cases with 25 sides were treated with a follow-up period of 3-6 months.All flaps were survived with good functions and the appearance of upper eyelids were satisfactory.Conclusions Subcutaneous pedicle flap based on the orbicularis oculi muscle is a reliable option for the treatment of xanthelasma.It has the advantages of abundant blood supply,convenience and effective.

The number of people with physical disabilities is increasing year by year, and the trend of population aging is more and more serious. In order to improve the quality of the life, a control system of accessible home environment for the patients with serious disabilities was developed to control the home electrical devices with the voice of the patients. The control system includes a central control platform, a speech recognition module, a terminal operation module, etc. The system combines the speech recognition control technology and wireless information transmission technology with the embedded mobile computing technology, and interconnects the lamp, electronic locks, alarms, TV and other electrical devices in the home environment as a whole system through a wireless network node. The experimental results showed that speech recognition success rate was more than 84% in the home environment.

Objective To study the effects of high salt intake on blood pressure and renin-angiotensin in male rats with different plasm androgen levels.Methods Thirty male Wistar rats were randomized to sham(n=10)or operated(n=10),or castration(n=10),or testosterone replacement after castarion(26.7 mg/kg,n=10)and fed with 8% NaCl for 8 weeks.Tall arterial pressure were recorded before,4 and 8 weeks after experiment.Serum PRA,plasma angiotensin Ⅱ(Ang Ⅱ)and testosterone(T)were determined by radioimmunoassey respectively. Results After 8 weeks high salt dietary,blood pressure was significantly increased in sham and testosterone replace ment rats(Sham operation group:137.3?4.0 vs the basal line:117.5?5.9 mmHg,testosterone replacement group: 134.4?5.2 vs the basal line:116.6?7.7 mmHg,P0.05).Concomitantly,sham operation or testosterone re placement rats had higher PRA and plasm Ang Ⅱ content compared with castrated rats(PRA:Sham operation 5.90 ?0.77 vs testosterone replacement group:5.69?0.47 vs castrated rats:4.90?0.55 mol/(L?h),P

Objective To evaluate the safety of dynamic anterior plate fixation for cervical distractive flexion injuries and compare its rigidity between different types of plate design. Methods Twelve sets of cadaveric calf spine were used in this test. All the specimens were made into distractive flexion injury models (C4-C5) ac- cording to Allen's method. After discectomy and grafting, they were randomized into three groups in which Orion, Codman, and Window instrumentations were used respectively. The stiffness of each construct was tested in flexion, extension, lateral bending and axial torsion conditions sequentially. Results Compared with an intact cervical spine, the range of motion (ROM) of an injured cervical spine increased whatever plate was applied. Orion in- strumentation presented stiffness the closest to that of the normal control, except for less torsional stiffness. Codman instrumentation provided stiffness close to that for normal and Orion groups only in lateral bending. Window's was the weakest mad not enough in all kinds of movement. Conclusions Static anterior fixation is the first choice for cervical injuries. Dynamic plate fixation may sacrifice stiffness to some extent, especially when a shifting kind of design is to be chosen.

0.05), CGI and HAMA. Safety analysis suggested that no significant differences were found in symptoms and frequency of side effects between the two groups.Conclusion Bupropion hydrochloride tablet is an effective and safe antidepressant. It has similar effect and safety compared with fluoxetine in the treatment of depression.

A reasonable and practicable quality standard was developed for mori liquid extract from different sources by TLC, HPLC and fingerprint technology. In TLC method, the compounds were separated on polyamide film using glacial acetic acid-water (1: 3) as mobile phase at a UV wavelength of 365 nm. All qualified samples had the spots of the same color as the control herb and substance. The RP-HPLC method was used to determine the content of mulberroside A with mobile phase of methanol-water (25: 75) at a wave-length of 326 nm. The mulberroside A was in good linear with a regression equation of Y = 46.965X (r = 0.999 6) in the range of 4.6 - 228 mg x L(-1). In 14 batches of samples, the mulberroside A in 4 batches of them was less than 0.5 g x L(-1), and was more than 2.0 g x L(-1) in the other batches. It was suggested that the content limit of mulberroside A should be no less than 1.5 g x L(-1). The HPLC fingerprints were evaluated by the similarities. It has found that the similarities of different mori liquid extracts were very low and the chemical diversity of mori cortex was the major factor of similarity. Moreover, the process impact was minimal. Thus the fingerprint was not included in this quality standard.

Myopia is one of the most popular eye diseases all over the world. The development of the current understanding of its mechanism is still limited. Many studies indicated that the growth factors closely related to eye development and myopia. Some growth factors with biological activity, such as transforming growth factor ( TGF ), fibroblast growth factor ( FGF ) and epidermal growth factor ( EGF ), have an impact on scleral thickness variation, the regulation of the development of myopia and so on, which plays a non-negligible role in the pathogenesis of myopia. In this paper, the function of various growth factors in myopia will be reviewed.
