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 study the protein expression and gene amplification of human epidermal growth factor receptor-2(Her-2)in adenocarcinoma of the gastroesophageal junction and its association with the clinicopathological features .Methods Immunohistochemical method and fluorescence in situ hybridization ( FISH) were used to detect Her -2 expression and gene amplification in 80 surgically resected gastroesophageal junction cancer tissue .We further analyzed the relationship between the gastroesophageal junction cancer histolog -ical differentiation ,as well as depth of invasion ,clinical stage and lymph node metastasis .Results Her-2 am-plification of gastroesophageal junction carcinoma by FISH was 22.5%,while the overexpression by IHC was 15%.Her-2 gene amplification and protein overexpression were correlated with the differentiation ,clinical TNM stage,invasive depth and lymph node metastasis of the carcinoma (all P<0.05).Her-2 expression was not asso-ciated with the patients age,gender,invasive depth and lymph node metastasis(P<0.05).Conclusion Her -2 protein expression and gene amplification may be a prognostic indicator for the patients with gastroesophageal junction cancer .The joint detection of Her -2 protein expression level and the gene amplification can guide the prognosis and therapy for adenocarcinoma of the gastroesophageal junction .

BACKGROUND: Posttraumatic stress disorder(PTSD) arises as a delayed and /or protracted response to a stressful event or situation of an exceptionally threatening or catastrophic nature. There have been reports about natural disasters causing PTSD, but there have been few reports about PTSDcaused by technological disasters. Our study investigated the mental status of those survivors after a serious explosion.OBJECTIVE: To investigate the characteristics and the factors of impact of PTSD caused by technological disasters.DESIGN: A case controlled study of the survivors of a momentous explosion.SETTING: A provincial mental health center.PARTICIPANTS: A serious explosion happened in Urumqi on September 8, 2000. Twenty-eight survivors(as the study group) who were still hospitalized for treatment 3 -5 months after the accident were involved in this study. And in the control group were 30 normal persons whose general demographic data were the same as those patients.METHODS: A psychiatrist told the subjects the following: The objective and meaning of the test, and explained the self-making questionnaire about their general condition, symptom checklist (SCL-90), self-rating anxiety scale (SAS), self-rating depression scale(SDS), cornell medical index(CMI), the questionnaire on dealing styles, the questionnaire on social support, and others-evaluating scale, incident effect scale(IES); a list of stress reaction symptoms.MAIN OUTCOME MEASURES:Main resulta:①Clinical feature of PTSD caused by the technological disaster.②the related factors to PTSD in the technologal disaster.Secondary results: Comparison of the results between the two groups in IES, CMI, SDS and SAS.RESULTS: A total of 22(79% ) survivors met the criteria as PTSD. There were significant differences in all the assessments(IES, CMI, SDS, SAS,SCL-90) between the study group and the control group (t =3.62-8.17, P ＜ 0.01 ) . The diagnosis of PTSD was positively correlated with the level of traumatic exposure( r = 0. 420, P ＜ 0. 05), and negatively correlated with the degree of satisfaction with the post-event solutions( r = 0. 420, P＜ 0.05), positively correlated with IES scoring and the level of heart pain ( r = 0. 389 - 0. 665, P ＜ 0. 01 ) . The total scores of IES were positively correlated with the level of exposure ( r = 0. 478, P ＜ 0.05 ).CONCLUSION: The incidence of PTSD after explosion was high, and its occurrence was related with the degree of exposure in the event and that of the satisfaction with the post-event solutions.

This article was aimed to study the relevance between traditional Chinese medicine ( TCM ) syndromes and the treatment of chemotherapy and targeted therapy , in order to provide theoretical support for TCM syndromes of lung cancer in the clinical application . Uniform TCM syndromes questionnaire was used in the TCM syndrome differentiation among lung cancer patients from the Oncology Department of Longhua Hospital, Shanghai University of Traditional Chinese Medicine and TCM Department of Shanghai Pulmonary Hospital. The analysis was made on correlation between distribution rules of TCM syndromes and chemotherapy and targeted therapy . The results showed that among primary lung cancer patients , the most TCM syndromes were syndrome of lung-yin deficiency , lung-q i deficiency , blood stasis in lung collaterals , spleen-q i deficiency , lung-yin deficiency with fire excess . There were certain correlation in TCM syndromes and different TCM therapeutic methods , in which targeted therapy had great significant effect on syndrome of lung-yin deficiency ( P < 0 . 05 ) , after targeted therapy syndrome of lung-yin deficiency increased obviously . It was concluded that there were some regulations in TCM syndromes of lung cancer which take syndrome of lung-yin deficiency, lung-qi deficiency, blood stasis in lung collaterals, spleen-qi deficiency, lung-yin deficiency with fire excess. There were certain correlation in TCM syndromes and different TCM therapeutic methods , after targeted therapy syndrome of lung-yin deficiency increased obviously .

ObjectiveTo avoid the complications such as scar,alopecie,scalp numbness,hematoma etc,resulted from the conventional coronal incision rhytidectomy,and to explore and solve the issues about endoscopic frontal and temporal rhytidectomy.MethodsThrough 3-5 short incisions in hairline,we dissected under frontal periosteum or gales aponeurotica and in superficial layer of deep temporal fascia.The frontal and temporal cavitites were feedthrough at temporal crest.The corrugator supercilii muscle,superciliary depressor muscle,frontal muscle and orbicularis oculi were treated.Sufficient dissection was done under the periosteum of os orbitale.ResultsThis method had been applied in 186 patients with forehead lift.After operation,transient paralysis of facial nerve frontal branch were found in 3 patients.The depression of glabellum and lateral canthus were found in 5 patients.The depressions were corrected by autologous fat injection. Other 178 patients' results were satisfactory.ConclusionsEndoscopic frontal and temporal rhytidectomy has some advantages,such as minute invasion,less hemorrhage,few complications,and stable operation result,etc.Compared to the conventional coronal incision rhytidectomy,this method will be used more widely.
