Objective To analyze the effect of overweight on appendicitis and laparoscopic surgery.Methods Clinical data of 200 patients with laparoscopic appendectomy were analyzed retrospectively.Overweight and non-overweight patients were compared.The risk factors of appendicitis were analyzed.Results The operation time [(56.19 ± 30.42) min vs.(48.40 ± 21.03) min] and length of stay [(5.35 ± 2.04) d vs.(4.52 ± 1.49) d] between the overweight and non-overweight groups had statistically significant differences (t =2.040,P =0.043,t =3.219,P =0.002).Overweight was correlated with appendix inflammation (OR =0.149,P =0.000).Conclusion Over weight patients are prone to develope into complicated appendicitis.It should take surgeon's attention for more difficult operation and more complication.

Objective To study the effect of surgery combined with 125I radioactive particles and chemotherapy in advanced gastric antrum cancer. Methods The data of 45 patients with advanced gastric antrum cancer were collected. The nutritional status, quality of life and survival time of patients in surgery combined with 125I radioactive particles and chemotherapy group (group A, 23 cases) and chemotherapy group (group B, 22 cases) were compared. Results The average period that patients canˊt eat through the mouth in group A was 10.22 months, it was 6.32 months in group B, and the difference between group A and group B was statistically significant (t= 3.765, P= 0.001). There were statistically differences in quality of life scores between the two groups at 3rd month and 9th month [3rd months: (73.48 ±19.21) scores vs (59.09 ± 24.86) scores, t= 2.178, P= 0.035; 9th month: (42.17±14.55) scores vs (32.05±21.10) scores, t= 3.43, P=0.001]. There were statistically differences in nutritional status between the two groups at 3rd month and 9th month (χ2 = 9.846, P= 0.020; χ2 = 7.713, P= 0.049). At 9th months, 7 patients died in group A and 13 patients died in group B, and there was a difference between the two groups (χ2= 3.964, P= 0.046). The overall survival rates of 12 months in two groups had not difference (P= 0.119). Conclusion The treatment of surgery combined with 125I radioactive particles and chemotherapy can improve the nutritional status and quality of life in patients with advanced gastric antrum cancer, and extend life appropriately in one year.
