Objective · To establish a replicative senescence model of human gingival fibroblasts (hGFs), investigate changes in aging related biological characteristics, and provide an efficient cell model for further study on the aging in periodontal diseases. Methods · hGFs were isolated from healthy gingival tissues and cultured with tissue block method in vitro. The tissue source was verified with immunofluorescence. hGFs were continuously cultured and cumulative population doublings (CPD) were calculated and used to draw the curves. Changes in the proliferative capacity of hGFs with CPDs of 10.82, 20.65, 29.52, 42.22, 60.79, and 70.03 were examined with CCK-8. Real-time PCR was used to evaluate changes in the mRNA expression of senescence-related genes p16INK4a and p21Cip1. Results · CPD curves showed that after continuous culture, the CPD value increased gradually and became stable after achieving 70.03. hGFs became flatter and more cell rocessesappeared with the increase of CPD value. The cell proliferative capacity declined and mRNA levels of p16INK4a and p21Cip1 significantly increased (P=0.000). Conclusion · A replicative senescence model of hGFs is established throughcontinuous culture. CPD curves can reflect the aging of hGFs.

OBJECTIVE:To investigate the effects of perioperative application of Eucalyptol,limonene and pinene(ELP)en-teric soft capsules on therapeutic efficacy and prognosis in children after grommet insertion of chronic secretory otitis media. METH-ODS:92 cases(145 ears)of chronic secretory otitis media were divided into 2 groups by random number table method,including 46 cases in observation group(68 ears)and 46 cases in control group(77 ears). Both groups received grommet insertion under gen-eral anesthesia by otomicroscope. Control group was not given any drugs;observation group was given ELP enteric soft capsules 1.2 g,bid,from 3 d before operation to 5 d after operation. Subjective therapeutic efficacy and pure tone audiometry of 2 groups were observed 3 days,5 days,2 weeks,1 month and 3 months after surgery as well as acoustic impedance monitoring in children with tube withdrawal from ear 1 month and 3 months after surgery. RESULTS:The total effective rates of observation group 3 days,5 days,2 weeks,1 month and 3 months after surgery were 72.06%,82.35%,85.29%,89.70%and 95.59%;those of con-trol group were 59.74%,66.23%,80.52%,87.01% and 92.21%,with statistical significance(P<0.05). The pure tone audiome-try score of observation group 3 days,5 days,2 weeks,1 month and 3 months after surgery were significantly lower than those of control group,with statistical significance(P<0.05). Therapeutic effective rates of acoustic impedance monitoring in children with tube withdrawal from ear 1 month and 3 months after surgery were 77.78% and 90.48% in observation group,which were signifi-cantly higher than 61.54% and 81.48% in control group,with statistical significance(P<0.05). CONCLUSIONS:The periopera-tive application of ELP enteric soft capsules can significantly improve function recovery and hearing level in children after grommet insertion of chronic secretory otitis media.

Objective To analyze the prognostic factors of patients with leukemia treated with single fraction total body irradiation (SFTBI) followed by hernatopoietic stem cell transplantation (HSCT).Methods From January 2001 to September 2008, 102 patients received HSCT. The differences of the survival rate, relapse rate and incidence of interstitial pneumonia (IP) between groups regarding different genders, ages, pathological types, transplantation methods and TBI parameters were compared and the factors related with the survival rate, relapse rate and incidence of IP were analyzed. Results The followup time ranged from 15 to 1482 days (median, 406 days). The follow-up rate was 95.1%. 86 and 55patients were followed up more than one year and three years. The 1-and 3-year survival rates were 59.0%and 44.0%. In univariate analysis, the 3-year survival rate was signifcantly different between the groups with and without relapse before transplantation (20% vs. 55%, χ2 = 6.33, P = 0. 012), allogeneictranplantation versus autologous tranplantation (39% vs. 68%, χ2 = 8.06, P = 0.005), grade 3 or more acute graft versus host disease (aGVHD) and grade 0 -2 aGVHD (0% vs. 54%, χ2 = 7.52, P = 0.006),with and without relapse after transplantation (19% vs. 58%, χ2 = 10.13, P =0.001), with and without IP (23% vs. 58%, χ2 =8.35, P=0.004). Multivariate analysis showed that grade 3 or more aGVHD was the only statistically significant prognostic factors (χ2 = 12. 74 ,P =0. 000). The l-and 3-year relapse rateswere 30. 0% and 50. 0%. The incidence of relapse was obviously higher in the group with relapse before transplantation than that without (47% vs. 16%, χ2 =7. 32, P=0. 007). Multivariate analysis showed thatrelapse before transplantation was a significant factor predicting relapse after transplantation (χ2 = 9. 39,P =0. 020). The cumulative incidence of IP was 35.0%. The incidence of IP was different between groups with dose homogeneity > 3% and ≤ 3% (27% vs. 4%, χ2 = 5. 21, P = 0. 023), with and without acute parotitis (34% vs. 3%, χ2 = 14. 15, P= 0.000), allogeneic transplantation group and autologous transplantation group (31% vs. 8%, χ2= 7.70, P= 0.006). Multivariate analysis showed that transplantation methods, acute parotitis and dose homogeneity were statistically significant factors in predictingIP (χ2 = 10. 08 , 10. 08 and 7.69 , P = 0. 002 , 0. 002 and 0. 010 , respectively) . Conclusions Patients who develop grade 3 or higher aGVHD have poor prognosis. Dose homogeneity influences the incidence of IP. Patients undergoing allogeneic transplantation are apt to have IP. Acute parotitis is related with IP and might be a predictor.
