?AIM: To evaluate the effects on recovering of corneal wound and postoperative discomfort of different methods for primary pterygium.?METHODS: Forty-seven cases ( 60 eyes ) of primary pterygium were excised under microscope with limbal epithelial transplantation, with sharp dissection ( 24 cases, 30 eyes, Group A) and blunt dissection (23 cases, 30 eyes, Group B).All cases were followed up for 1d to 1mo.?RESULTS: The recovering of corneal wound was better in Group B on 1st day and 3rd day after surgery.Pain, photophobia and tears, foreign body sensation were more serious in group A on 1st day after surgery with a statistically significant difference (P=0.005,0.015,0.012). Pain, photophobia and tears, foreign body sensation were more serious in Group A on 3rd day after surgery with a statistically significant difference ( P=0.019,0.018, 0.015).There was no statistically significant difference on 1wk and 1mo after surgery (P>0.05).? CONCLUSION: Compared with sharp dissection, primary pterygium excised with blunt dissection can significantly improve recovering of corneal wound and postoperative discomfort.

Objective To investigate the prognostic value of heart rate turbulence (HRT) in patients with chronic heart failure (CHF). Methods From October 2006 to May 2009, a total of 96 elderly CHF inpatients were selected, and the clinic data were recorded. Based on the echocardiogram and dynamic electrocardiogram, the differences of sinus HRT index of patients with different cardiac function classification were analyzed. During 9-28 months medical follow-up, the treatment endpoint was death from heart disease. Based on Logisitc regression, the prognostic values of HRT, age, hypertension, diabetes, myocardial infarction (MI), left ventricular ejection fraction, ACEI and β- adrenergic blocker for death of CHF patients were analyzed.Results There was no significant difference in HRT between grade Ⅱ and grade Ⅲ cardiac function (χ~2 = 1.60, P>0. 05), and between grade Ⅲ and grade Ⅳ cardiac function (χ~2 = 1.43, P>0. 05). But there was significant difference in HRT between grade Ⅱ and grade Ⅳ cardiac function patients χ~2 =9.84, P<0. 05), and HRT was weaken in grade Ⅳ group. The average follow-up time was (18. 0±9.6) months. Of all 96 patients, there were 34 dead of heart disease. There were correlations of death of CHF with HRT, low LVEF (≤ 45%), age (≥65 years), diabetes, MI and classification of heart function. Conclusions The sinus HRT in CHF patients has a favorable prognostic value.

Objective:To observe the spleen-strengthening and mind-regulating acupuncture method on the quality of life of children with cerebral palsy (CP) and their parents.
Methods:A total of 76 CP children were randomly allocated into a treatment group (n=38) and a control group (n=38) according to their visit sequence. The CP children and their parents in both groups received the same psychological counselling. The CP children in the treatment group were intervened with spleen-strengthening and mind-regulating acupuncture method, versus routine acupuncture method in the control group. The parents of CP children in the treatment group were intervened with three mind-regulating points, versus placebo in the control group. The developmental quotients were evaluated using the Gesell scale before and after treatment. The anxieties of parents were assessed using the self-rating anxiety scale (SAS) before and after treatment. The efficacies were evaluated using the comprehensive functional assessment of CP children.
Results:After 6 months of treatment, the Gesell scores of CP children and SAS scores of the parents were significantly improved in both groups, and there were intra-group and inter-group statistical differences (bothP<0.05). In addition, the scores of comprehensive functional assessment of CP children in the treatment group were significantly higher than those in the control group (P<0.05).
Conclusion:The spleen-strengthening and mind-regulating acupuncture method can effectively improve the comprehensive ability of CP children, alleviate the anxiety in parents of CP children, improve the quality of life of CP children and their parents, and play an active role in rehabilitative care of CP children.

To explore the feasibility of stable expression of Hantavirus H8205 strain G1 segment and human IL-2 fusion gene in Vero cells, and to examine the immune protection effects on mice vaccinated with this recombinant eukaryotic expression vector containing Hantavirus G1 gene and IL-2 gene. With the help of lipofectamine, the Vero cells were transfected with pcDNA3.1/HisB-IL-2-G1 and the positive cells were selected by G418. IFAT and SDS-PAGE electrophoresis were used to determine the stable transfection and expression of recombinant protein. Each mouse was inoculated with plasmids intramuscularly (i.m.) three times, 2 boosts were given at 2-week intervals, serum anti-hantavirus antibodies were detected by ELISA and neutralizing antibodies (NAb) were detected by Plaque Reduction Neutralization Test. The fusion protein expressed in Vero cells was 78 kD, corresponding to the estimated molecular size. The neutralizing antibody titers of mice with pcDNA3.1/HisB-IL-2-G1 were 1:20-1:80. IL-2/G1 fusion gene could be transferred in Vero cells and stably express the fusion protein. Specific humeral immune responses in mice can be induced with the recombinant eukaryotic expression vector containing the fusion gene, which lays the foundation for further development of therapeutic HTNV vaccine.
