Moderate to severe unilateral ptosis has previously been treated with levator resection or frontalis sling and cosmetic double fold in the opposite eyelid. This method often resulted in undesirable asymmetrical lid lag phenomenon in down gaze. From December 1991 to December 1994, we treated 65 cases of unilateral ptosis with frontalis sling or levator resection, and simultaneously cosmetic frontalis sling have been performed in the unaffected normal eyes of 41 patients and cosmetic double fold have been performed in the unaffected normal eyes of 11 patients. After 6 months of operation, authors survey the patients content. The number of cases of content were 4(36.36%) in 11 cosmetic double fold group and 31(75.6%) in 41 cosmetic frontalis sling group. The content after cosmetic frontalis sling was higher than cosmetic double fold. Asymmetrical lid lag phenomenon on downward gaze which is inevitable complication postoperatively was reduced by means of cosmetic frontalis sling of unafeected normal eye in unilatral ptosis. The authors expect that the patient will be more satisfied with the result of symmetrical lid lag in down gaze after cosmetic frontalis sling of unaffected normal eye in aesthetic aspect.

Aim To screen peptides binding specifically to anti-human PTA1mAbs from a random twelve-peptide phage-disp-layed library. Methods Series of PTA1mAbs(LeoA1、 1B11、 C9、 2D1、 2E9、 2G8、 2H2 and E8)were purified using protein-A affinity column. PTA1mAbs which could bind PTA1-Fc fusion protein binding to its ligand were confirmed by flow cytometry, and then used as target to screen phage library. After three rounds of affinity screening, the peptide sequences of positive phage clones were determined and analyzed. Results LeoA1 could block PTA1-Fc fusion protein binding to its ligand. 13 phages which could bind specifically to LeoA1 were isolated from phage library and further confirmed by ELISA. Conserved motifs were found among the sequences of the peptides. Conclusion It was shown that the conserved motifs were candidafe regions binding to PTA1 ligand,which is important to identify functional epitopes for seeking ligand of PTA1 and further investigation of biological function of PTA1.

BACKGROUND: The occurrence and severity of acute high-altitude disease(AHAD) are determined by the speed entering the highland, the altitude of highland and seasons. The association between obesity and AHAD has not been fully investigated.OBJECTIVE: To investigate the association between obesity and acute high-altitude in people exposed rapidly to the highland.DESIGN: Comparative observation.SETTING: Department of Cardiology, General Hospital of Chinese PLA and Department of Cardiology, Tibetan General Hospital of Chinese PLA.PARTICIPANTS: The experiment was conducted at the Department of Cardiology, General Hospital of Tibetan Military Area Command of Chinese PLA in August 2006. Totally 82 Henan subjects aged 28-45 years were selected from the male workers constructing the Qinghai-Tibet Railway and their managers with acute high-altitude exposure. They had never been to the highland before, and all agreed to the detection.METHODS: ①Every subject completed the AHAD self-report questionnaire at sea level and 12 hours and 24 hours after ascending high-altitude. The items in the questionnaire included symptoms of headache, gastrointestinal symptoms,fatigue or weakness, dizziness, and insomnia. Each symptom was graded from 0-3 with 0 as no symptoms, 1 as mild symptoms, 2 as moderate symptoms, and 3 as severe symptoms and a total score of 15. A score of 4 or more could by identified as AHAD. ②The height and body mass were measured to calculate the body mass (BMI). Those with BMI≥28 kg/m2 served as the obesity group [n =39, mean age (35±8) years], and those with BMI of 18.5-23.9 kg/m2 as the normal body mass group [n =43, mean age (35±8) years]. ③Arterial blood was taken to evaluate arterial oxygen saturation (SO2), arterial oxygen pressure (PaO2) and arterial carbon dioxide pressure (PaCO2) at baseline and 24 hours after ascending high-altitude. ④The measurement data was compared by t test.MAIN OUTCOME MEASURES: BMI, vital capacity of lungs, SO2, PaO2 and PaCO2 levels of obese and normal people.RESULTS: Totally 39 obese people and 43 normal people were involved in the result analysis. ①AHAD score: No symptom was reported at sea level in all participants (scored 0), but the AHAD scores in the obesity group were significantly higher than those in normal group 12-hour and 24-hour after ascending high-altitude. ②Blood gas analysis:At sea level, there were no statistical differences in the levels of SO2, PaO2, and PaCO2 between two groups (P > 0.05).But 24 hours after ascending high-altitude, SO2 and PaO2 of the obesity group were much lower than in the normal group (P< 0.01), and PaCO2 was significantly higher than in the normal group (P< 0.01).CONCLUSION: Obese men are more vulnerable to high-altitude hypoxia than people with normal body mass. Obesity is an important risk factor for the development of acute high-altitude disease.
