Objective To retrospectively compare analysis of two kinds of surgery which were nerve-sparing radical hysterectomy (NSRH) and the traditional radical hysterectomy (RH) for cervical cancer was done to find out the effect on urinary function in postoperative patients. Methods Among 57cervical cancer with clinical stage Ⅰ B1- Ⅱ A 31 cases treated with NSRH,26 cases treated with RH. The postoperative bladder function of the two methods were evaluated, and postoperative recovery of urinary function and postoperative recurrence of tumor were compared. Results The period of indwelling catheter for the postoperative patients with NSRH was (8.5 ± 3.2) days, obviously less than that for traditional RH patients which was ( 12.8 ± 3.8) days. The difference was statistically significant(P < 0.01 ). And two methods of postoperative patients were alive without tumor recurrence and metastasis after 1-4 years follow-up.Conclusions NSRH is better than traditional RH in remaining pelvic autonomic nervous system and improving the early urinary function of postoperative patients of cervical cancer. Otherwise, it doesn't effect the radical cure of tumor.

OBJECTIVETo investigate the hematological and molecular characteristics of hemoglobin Q-Thailand in Guangxi, so as to provide reference data for hemoglobinopathy screening.

METHODSA total of 51088 samples were screened by capillary electrophoresis. Samples suspected with Hb Q-Thailand were processed with blood cell count and DNA sequencing. Gap-PCR and PCR-reverse dot blotting were used for the detection of common mutations of alpha and beta thalassemia.

RESULTSThe carrier rate of Hb Q-Thailand in Guangxi was 0.06%. The hematological phenotype index(HGB, MCV, MCH, Hb Q-Thailand, Hb A2, Hb QA2) of 28 Hb Q-Thailand heterozygous samples were (125.60±22.30) g/L, (78.22±4.81) fl, (25.79±2.14) pg, (27.37±2.72)%, (1.89±0.22)%, (0.69±0.16)%, respectively, and of 2 Hb Q-Thailand heterozygous combined with beta-thalassemia samples were (125.00±18.39) g/L, (69.65±5.02) fl, (22.00±0.0) pg, (14.80±0.71)%, (4.45±0.07)%, (0.95±0.71)%, respectively. A statistical difference was found in hematological phenotype index between the two groups except HGB (P<0.05).

CONCLUSIONIn Guangxi, the detected Hb Q-Thailands were mainly heterozygous. Part of Hb Q-Thailand heterozygotes had normal red blood cell parameters, but can still be detected by hemoglobin electrophoresis. When combined with other types of thalassemia, these heterozygotes may still exhibit reduced MCV and MCH or various degrees of anemia.
