Objective:To explore the correlation among the expression of p53, p21, and PCNA in the negative surgical margin of early laryngeal cancer and its relationship with local recurrence of the cancer. Methods:Data of 92 patients with early laryngeal cancer admitted to the Tangshan Union Hospital from 2004 January to 2010 December were selected. Immunohistochemical method was used to detect the expression of p53, p21, and PCNA in the negative surgical margin tissues of cancer. All patients were followed up for two years to observe survival status and tumor recurrence. Results:The expression of P53, p21, and PCNA had no differences in the cancer tissues in terms of grade and stage. Two years after the surgery, 16 of the 92 patients with laryngeal cancer presented recurrence with a rate of 17.39%. The recurrence rates of expression of p53, p21 and PCNA protein in the positive cut edge were 50.00%, 34.21%and 33.33%, significantly higher than those of negative ones (8.33%, 5.56%and 9.68%). The positive rates of the three proteins were higher in the recurrence specimen than in the non-recurrence while there was a significant correlation between expression of PCNA and p21 (P<0.01). The expression of both p21 and p53 in laryngeal carcinoma was also significantly correlated with the negative margin. Con-clusion:The expression of p53, p21, and PCNA in the surgical margin of early laryngeal cancer are valuable biological markers for the prognosis of these patients. Thus, combined detection of p53, p21, and PCNA in laryngeal margin tissues can be used as a predictive in-dicator of the recurrence.

Purpose To compare the therapeutic effects of CO2 laser resection and traditional split laryngeal surgery on the early laryn-geal cancer, and to examine relationship between the expression of p27 and PTEN and clinical prognosis in early laryngeal squamous cell carcinoma. Methods 85 patients who underwent CO2 laser resection surgery and 46 patients who underwent split laryngeal surger-y were selected and the occurrence rates after surgery were observed. SP immunohistochemical method was uesd to detect the expression of p27 and PTEN in tumor resection marginal and their surgical margine tissues. Clinical data were collected and all patients were fol-lowed up. Results In the more than two-year follow-up study, 14 of 85 patients in CO2 laser treatment group ( recurrent group) pres-ented with local recurrence and the recurrence rate was 16. 5%, while 6 of 46 patients in split laryngeal surgery group presented with local recurrence and the recurrent rate was 13. 0%. There was no statistical significance in recurrence rate between the two groups ( P> 0. 05). 10 of all the none recurrent patients did not follow the doctor’s advice to quit smoking after the operation, while 12 in the recurrent patients did not, the difference between the two groups was statistically significant (P<0. 01). The positive rate of p27 and PTEN in laryngeal carcinoma tissues and the cancer adjacent tissues ( negative surgical margin tissues ) was 43. 5% ( 57/131 ) , 80. 2% (105/131) and 48. 9% (64/131), 83. 2% (109/131), respectively, with a significant difference (P<0. 01). The positive rate of p27 and PTEN in laryngeal carcinoma tissues of the recurrent group and non recurrent group was 20. 0% (4/20), 47. 7% (53/111) and 10. 0% (2/20), 55. 9% (62/111), respectively, with a significant difference (P<0. 05). While the positive rate of p27 and PTEN in tumor resection marginal tissues of the recurrence group and non recurrence group was 50. 0% ( 10/20 ) , 85. 6% ( 95/111) and 40. 0% (8/20), 91. 0% (101/111), the difference was also statistically significant (P<0. 01). Conclusions There was no statistically significant difference in tumor recurrence rate between CO2 laser surgery and traditional split laryngeal surgery. Postoper-ative recurrence is closely related to resume smoking. The recurrence rate of p27 and/or PTEN negative patients was higher than that of the opposite ones which should be followed up closely after treatment.

AIM: To evaluate the efficacy of phacoemulsification and intraocular lens implantation surgical intervention of complicated cataract in patients with uveitis.
●METHODS:Retrospective study. A total of 57 cases (57 eyes ) with complicated cataract with uveitis were involved in the study from Jan. 2015 to Dec. 2015. All cases underwent phacoemulsification and intraocular lens implantation surgery successfully. The postoperative reaction, effect, complications and so on were retrospectively analyzed after phacoemulsification and intraocular lens implantation surgery. The date of visual outcome was analyzed using Non - parametric Wilcoxon test.
●RESULTS: lris were bleed in 21 eyes ( 37%) , 4 eyes ( 7%) with posterior capsule rapture and posterior chamber intraocular lens was not implanted in 4 eyes ( 7%) . The uncorrected visual acuity ( UCVA ) was significantly increased after surgery. The UCVA of 8 eyes (14%) were 0. 1 or better before surgery, and the UCVA of 42 eyes (74%) were 0. 1 or better 3mo after surgery, the difference was statistically significant ( Z=23. 42, P<0. 001). The corneal edema (17 eyes, 30%), uveitis (2 eyes, 4%) and intraocular hypertension ( 1 eyes, 2%) were appeared in postoperative 1d. The corneal edema (3 eyes, 5%) was appeared in postoperative 1wk. The uveitis ( 1 eyes, 2%) was appeared in postoperative 1mo. The corneal edema (1 eyes, 2%), uveitis (2 eyes, 4%) , intraocular hypertension ( 1 eyes, 2%) and after-cataract ( 3 eyes, 5%) were appeared in postoperative 3mo.
● CONCLUSION: The phacoemulsification combined intraocular lens implantation surgical intervention of complicated cataract in patients with uveitis has good effect and fewer complications.

BACKGROUND:Calcaneus is a kind of irregular bone, with complicated three-dimensional structure. Calcaneus is often measured with X-ray plain film, while spiral CT three-dimensional imaging is a potent technology for anatomic measurement and has good application prospect. However, little is known about it. OBJECTIVE:To measure calcaneal anatomic data in Chinese peoples with spiral CT three-dimensional reconstruction and to explore its clinical significance.
METHODS:Calcaneal spiral CT three-dimensional reconstruction in 100 Chinese adults (including 50 males and 50 females) were performed. The length, width, height of calcaneus, and Bohler’s and Gissane’s angles were measured after reconstruction, and compared with the data of westerners.
RESULTS AND CONCLUSION:The mean length, width and height of the Chinese calcaneus were respectively (74.60±5.06) mm, (29.71±2.93) mm and (45.23±4.46) mm in male group, and (71.48±5.36) mm, (26.65±3.01) mm and (42.23±4.49) mm in female group. There were no significant differences between male group and female group in al the above parameters (P>0.05). There was no significant difference in the Gissane’s angle between the two groups (123.3±8.5° versus 122.7±8.9°;P>0.05). The Bohler’s angle in male group (35.98±4.34)° was significantly lower than that in female group (38.81±4.43)° (P<0.05). The length, width and height of Chinese calcaneus were significantly lower than those of westerners (P<0.05). The Bohler’s angle and Gissane’s angle in Chinese adults showed no statistical significance compared with the westerners (P>0.05). Experimental findings indicate that, the length, width and height of Chinese calcaneus in female were lower than that in male, but Bohler’s angle is significantly higher than that in male, there was no significant difference in Gissane’s angle between males and females. Compared with the data of westerners, the length, width and height of Chinese adult calcaneus are significantly decreased, and no difference is found in Bohler’s angle and Gissane’s angle.
