Acute paralysis is one of commonest childhood neurological diseases with multiple etiologies.The hand foot mouth disease,intracranial infection,stroke and so forth become the main causes of acute paralysis.Timely treatment of the primary disease and early implementation of the motor function rehabilitation can prevent and decrease motor disability.

Objective To investigate the role of Xiao Ban Xu, a compound Chinese traditional medicinal prescription, on the proliferation of keloid fibroblasts, so as to provide experimental evidence for treating keloid by Chinese traditional medicine. Methods By using hydrocortisone as the experimental control agent, different doses of Xiao Ban Xu were added into cell culture solutions in vitro from 6 samples of keloid fibroblasts (KFB) and 6 samples of normal fibroblasts (NFB). The proliferous activities of KFB and NFB were detected by 3H-TdR method at 12, 24 and 48 hours, respectively. Results The proliferation of NFB and KFB was inhibited by Xiao Ban Xu at 10 ?g/ml, 100 ?g/ml and 1 000 ?g/ml as well as hydrocortisone at 1?10 -7 mol/L at 12, 24 and 48 hours, respectively ( P

Objective To investigate the state of the art technique of ectropion correction. Methods Orbicularis oculi myocutaneous flap on both upper and lower eyelids was used to correct ectropion. Results From Feb.1994～June 2001, the authors performed correction of ectropion for 24 patients. Among them 19 patients were followed up, and the period of follow-up ranged from 3 weeks to 2 years. All of the followed patients received good results except one who had partial necrosis of the orbicularis oculi myocutaneous flap. Conclusion Orbicularis oculi myocutaneous flap has a rich blood circulation. The ratio of its length and width can be made to be 6∶1, and its contour can be trimmed as one's will. In addition, the flap can be transferred flexibly, and the incision in donor site is hidden in nature wrinkle. With this flap, the ectropion can be repaired as an aesthetic unit in one stage.

Objective　To research the procedure of male face-lift. Methods　According to the distribution features of skin and hair in the male face, the flap assigment at the incision point was improved. Results　From 1995 to 2000,25 cases of male facelift were performed, aged from 37 to 68. Postoperative follow-up of 1 to 24 months showed the results were satisfactory. Conclusion　 Male face-lift has satisfactory rejuvenation results by improving the incision design and skin-lifting technique.

Objective To evaluate the application of three-dimensional (3D) scanning in the measurements and analyses of breast morphology changes that occur after breast augmentation. Methods Pre- and postoperative breast 3D images were obtained in 18 patients (36 breasts) undergoing augmentation mammaplasty by 3D scanning. All implants were round sillicone and planted under pectoral muscle. Average implant volume was 232.2 mL, and average projection was 3.46 cm. The number of implants in low profile implant group was 12( h ＜ 3.0 cm), and 16 in moderate group ( 3.0 ≤ h ＜ 4.0 cm), 8 in high group ( h ≥ 4.0 cm). The following parameters were measured by Geomagic 10.0: volume, projection, angle and distance of key landmarks, and symmetry degree. Results The increased volume of breast was corresponding with the implant volume (P ＞0.05). Postoperative breast projection was 12.9 %, less than expected projection (preoperative + implant projection). The values in low, moderate, and high profile group were 5.2 %, 15.1%, and 20.2 %,respectively. Conclusion 3D scanning is a quick, convenient, accurate and non-contact method for measurement of breast morphology, and it is promising in breast plastic surgery in the future.

Objective To evaluate the effect of injecting transplantation of autologous fat granules in the treatment of soft tissue depression in face. Methods Autologous subcutaneous fat granules were obtained by liposuction and implanted into the facial sites of soft tissue depression by injection. Results From 1996 to 2002, 56 affected sites were treated, in which 45 sites were given fat granule injection once and 11 sites twice. The volume of fat granules ranged from 1.5ml to 24ml with an average of 8.9ml. Among the 43 sites in 28 cases followed up for more than 6 months, including 8 sites (18.6%) treated twice, 38 ones showed excellent or good augmentation results for 6 months, the percentage being 88.4%. No serious complications occurred. Conclusions Local injecting transplantation of autologous fat granules is effective for correcting the simple soft tissue depression in face. Repeated injections may be needed in some cases. The procedure is simple, safe and minimally invasive.

Objective To investgate the efficiency of autologous fat grafting for breast augmentation by improving low negative pressure mechanical liposuction.Methods A total of 37 cases of breast augmentation by autologous fat grafting were reviewed;group A included 19 cases of improved low pressure mechanical liposuction,and group B had 18 cases of traditional syringe liposuction.Respectively,the operating time of harvesting 800 ml fat granules (standing 30 mins) were recorded,and operative blood loss by testing the red blood cell count of lower mixed liquid was calculated,and then growth increment of nipple chest circumference of 6 months after operation were measured.The valid follow-up satisfaction scores were counted.Results The operating time of harvesting 800 ml fat granules were (53.32±4.73) mins for group A and (80.78±7.86) mins for group B,respectively;operative blood loss was (81.58±10.80) ml for group A and (72.94±13.45) ml for group B;All P＜0.05.The valid follow-up satisfaction scores were 78.9％ (15/19) for group A and 77.7％ (14/19) for group B.Growth increment of nipple chest circumference of 6 months after operation between groups were no statistical significance (P＞0.05);but the remarkable difference within both groups in internal comparison existed between 6 months and 1 month after operation (P＜0.05),also between 3 months and 1 month after operation (P＜0.05).Conclusions Improved low pressure mechanical liposuction in breast augmentation by autologous fat grafting is able to enhance the surgical efficiency evidently and shorten the operating time significantly.

Objective To investigate the significance of administration of ionic contrast media with dexamethasone in preventing side effect during enhanced CT scanning. Methods We prospectively studied 520 patients who had enhanced CT scans and divided them into two groups: 259 patients received ionic contrast medium with dexamethasone (dexamethasone group); 261 patients received ionic contrast medium without dexamethasone (contrpl group). The side effects of the patients in two groups with different ages were compared. Results There were 19 patients with side effects in dexamethasone group (7 3%), 20 patients with side effect in control group(7 7%). The side effect rate in those patients over the aged 20 years and under the aged 60 years was higher than other age groups. The side effect rate was similar between dexamethasone group and control grouop.Conclusion Administration of Ionic contrast media with dexamethasone during CT scanning can not obviously decrease the incidence of side effect.

Objective To assess the age-specific sleep time among children 2 to 12 years of age in Yuexiu district,Guangzhou,China,and to identify the related factors.Methods 1734 children,aged 2 to 12 years were randomly selected from two elemental schools and two kindergartens in Yuexiu district of Guangzhou under strict quality control system,their parents were interviewed with questionnaire to look into their familial and social environment,as well as sleep related factors.Results The total sleep time among children less than 6 years of age in Yuexiu district,Guangzhou was less than that among children the same age in other provinces in China.The factors were related to children's inadequacy of total time included age,sleep problems,the history of sleep snoring in father and mother,feeding manners,difficulty at sleep onset.Conclusion The total sleep time among children at lower age in Yuexiu district,Guangzhou is on the low side.The main influencing factor of insufficiency of sleep time among children is the family environmental factors,the sleep time should be recognized by family and society.
