Objective To observe the curative effects of pterygium excision combined with autologous limbal stem cell transplantation in the treatment of primary pterygium.Methods 50 cases (72 eyes) of primary pterygium were selected in our hospital.According to the method of random number table,50 canses were divided into the control group (37 eyes) underwent pterygium excision and the study group (35 eyes) received autologous limbal stem cell transplantation on the basis of the control group,with 25 cases in each,and the efficacy were compare between the two groups.Results The healing time of study group[(3.02±0.37)d] was significantly shorter than in the control group[(6.85±0.48)d](t=2.95,P=0.01) and the recurrence rate (20%) was significantly lower than in the control group (52%) (x2=10.35,P=0.03),and the postoperative complications rate (8%) was significantly lower than in the control group (36%) (x2=13.94,P=0.03).Conclusion Compared with pure pterygium excision,pterygium excision combined with autologous limbal stem cell transplantation in the treatment of primary pterygium has higher clinical efficacy,which can effectively shorten the repair time and reduce recurrence rate,with high safety,so it is worthy of further promotion and application in clinic.

Objective To define the nuclear agrresome formation is determinated by which part of the UL76 of
HCMV. Full-length, conserved N terminal and unconserved C terminal of pUL76 were constructed to eukaryotic ex-pression plasmid pEGFP-N1 . Methods Primers were designed to amplify full-length and different part of pUL76 according to standard sequence of HCMV AD169 which had been submitted to GenBank(FJ527563. 1). These frag-ments were constructed to eukaryotic expression plasmid pEGFP-N1 . The recombinant plasmids were designated pEGFP-UL76,pEGFP-UL76N, pEGFP-UL76C respectively. Double digestion and sequencing were performed to verify the accuracy of recombinant plasmids construction. Empty vector and three recombinant plasmids were transi-ent transfected to HELF and HepG-2 cells respectively. Reverse transcriptation PCR and Western blot were per-formed to detect the RNA and protein expression level respectively. Different nuclear aggresome formations were visualized with an Olympus fluorescence microscopy. Results pEGFP-N1 and pEGFP-UL76N were unable to in-duce nuclear aggresome formation, whereas pEGFP-UL76 and pEGFP-UL76C were able to elicit nuclear aggresome formation. Conclusion The unconserved C terminal of pUL76 is sufficient to induce nuclear aggresome formation.

Objective To propose a grasp torque control based on experimental learning and haptic feedback to facilitate the manipulator in dexterous manipulation.Methods An experience database was built firstly,and then the object was recognized by tactile feedback in the grasp task.If the object had been experitentially grasped,the torque was output based on the database.In case a new object was grasped,the optimal output torque was calculated by iterative learning.Results The experiment showed that the robot hand could find the experiential output torque quickly when encountering the object in database and calculate the torque by iterative learning to achieve grasp task.Conclusion The experiential database grows up when the robot hand learns more and more experience.It can fast output torque like human in the grasp task.

Objective: To analyze the validity of the lie scale in University Personality Inventory (UPI). Methods: Relationship between choice of lie scale and UPI score , mental health was analyzed by UPI questionnaire of 2958 freshers.Results: Average every student chosed 2.37 lie items. Relationship between UPI score and numbers of the choosed lie items showed negative correlation. Numbers of lie items that was chosen by First class students was fewer than that was chosen by second class students, and numbers of lie items that was chosen by second class students was fewer than that was chosen by third class students.Conclusion:UPI lie scale had lost validity to evaluate attitude of respondent, so UPI lie scale should be revised.

Objective:To identify the influence of occupational stress on occurrence of hypertension.Methods:A prevalent cohort of 964 male workers employed for at least 3 years with different occupational stress were investigated with Occupational Stress Index, hypertension was diagnosed by WHO criteria of 1996. Results:The occupational stress was a risk factor for hypertension with RR=1.70 and in a dose-effect pattern after adjusted for other factors. In high exposure group, the adjusted incidence density was 12.47/per 1000 person-years with RR=2.99, in the medium exposure group, that was 8.81/per 1000 person-years with RR=2.11, that of low exposure group was 4.17/per 1000 person-years, the differences between different groups had statistic significance. When the length of exposure was more than 10 years, the adjusted incidence of hypertension increased significantly in high and medium exposure groups.Conclusions:Causality between occupational stress and hypertension exist, but it needs long exposure of at least 10 years for occurrence of hypertension.
