RESUMEN
OBJECTIVE: To evaluate the expression and clinical significance of H2AX in cervical squamous carcinoma. MATERIALS AND METHODS: The expression of H2AX in the cervical squamous carcinoma of 37 patients and in the normal cervical tissue of 15 patients was detected by immuneohistochemical method. Chi-square, correlation analysis, and Kaplan-Meier were utilized to analyze the data. RESULTS: The positive expression rate of H2AX in cervical squamous carcinoma was higher than that in normal cervical tissues (p = 0.016) . The expression of H2AX was negatively correlated with FIGO staging, vaginal invasion, and parametrial infiltration (p < 0.05). Survival analysis showed the expression intensity of H2AX had no significant effect on the prognosis. CONCLUSION: H2AX was an anticancer protein for cervical squamous carcinoma.

The laparoscopic subtotal hysterectomy (LSH) was given to a patient whose uterus was about seven-month pregnanacy because of fibroids. The biggest problem was the operation space and visual field was too narrow. Different from the usual procedure we do, we morcellated the uterus at the beginning to expand the space. Loop ligature of the uterine isthmus was adopted to block uterine ateries before morcellating the uterus. After the adnexa exposed totally, we started to cut off the round ligaments, proper ligaments and fallopian tubes like usual. It was the first time we did LSH for so giant uterus in our hospital, although which was usually suitable for the uterus smaller than four-month pregnancy. But if the uterine ateries can be blocked effectively at the beginning, the uterus can be morcellated and the space will be enlarged. The laparoscopic subtotal hysterectomy will also be completed successfully.
