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.

Objective To investigate the volume of hippocampal formation in normal adult using coronal magnetic resonance imaging. Methods 3D-fSPGR sequence was used to depict the brain in 68 healthy adult. The volume of hippocampus was calculated by drawing the outline of 10 coronal hippocampal formation images acquired equally form posterior border of rostrum corpus callosum to anterior border of the splenium. Data were analysed using the SPSS 17.0 software. Results In the coronal plane images of normal adult brain, the absolute volume of left and right hippocampal formation were 2 319.63-2 610.73 mm3 and 2 447.52-2 749.50 mm3 respectively . The relative volume of left and right hippocampal formation were 2 319 . 87-2 602 . 47 mm 3 and 2 443.96-2 755.89 mm3. There were no correlation between hippocampal volume and age (r = 0.084, P = 0.549. Significant gender differences (t=2.500, P=0.029) were observed between absolute volume of right hippocampal formation in the youth group. There were significant differences in the absolute volume (t = -2.571, P = 0.022), relative volume (t = 2.600, P = 0.021) among the right and left hippocampal formation. Significant absolute volume differences (P = 0.038) were observed between the middle-aged group and the youth group among the hippocampal formation of women. Conclusion No significant differences were observed in age, gender among the hippocampal volume of normal adult, and there was a significant difference between the left and right hippocampal formation volume.

BACKGROUND: Appropriate direction and angle of traction for the vertebral artery type cervical spondylosis(CSA)make significant effect.Selective angiography is recognized as"gold standard"to diagnose the vascular disease.Although magnetic resonance angiography as a non-invasive examination,there exist shortcomings such as a longer time checking,vulnerable to man-made factors,a certain aggressive feature.OBJECTIVE: Through the use of color Doppler flow imaging(CDFI)and transcranial Doppler sonography(TCD)adding the test of turning neck,to analyze the change of blood current parameter before and after the tractions from different directions and angles.METHODS: 240 cases suffering CSA were selected and divided into groups according to anatomy angle of lesion parts(upper cervical segments,lower cervical segments,mixed type)and traction mode,angel(anteversion sitting position 1°-10°,11°-20°,21°-30° groups,posterior extension sitting position 1°-10°,11°-20°,21°-30° groups,neutral position sitting position group).Local massage served as control group.The indexes of vertebral artery of neck part including inner diameter(D)of narrowest location,peak systolic velocity and average velocity of blood were measured by CDFI adding the test of turning neck.The indexes of left vertebral artery,right vertebral artery and basiiar artery including peak velocity(Vp)of period of contraction and mean velocity(Vm)of blood were measured by TCD adding the test of turning neck.RESULTS AND CONCLUSION: ①We determined vertebral artery type of cervical spondylosis on the base of anatomic site. On the basis of diseased region,we divided cervical syndrome into 3 types.They were superior part(C1-C3),inferior part (C4-C6) and commixture.it offers clinical guidance for traction therapy from spondylous morphous and mechanics.② We determined the gbest angle of traction.The therapeutic efficacy in posterior extension sitting position occupying 11-20~was better in upper hind neck;the therapeutic efficacy in anteversion sitting position occupying 11-20° was better in inferior neck; the therapeutic efficacy in anteversion sitting position occupying 1-10° was better in neutral position sitting position.③ We knew that CDFI and TCD are the convenient,non-invasive,safe and reduplicative methods to guide traction therapy in vertebral artery type of cervical spondylosis.

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.
