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 effects of growth-discordant twin pregnancies on neonatal thyroid stimulating hormone (TSH) level and congenital hypothyroidism (CH).Methods A total of 3 444 live-birth twin neonates born between January 1,2012 and December 30,2014 in Ningbo City were enrolled.Blood samples via heel puncture were collected and tested.Incidence of CH in singleton and twin neonates was compared.Deviation of birth weight larger than 25％ in twin neonates was set as the criteria for discordant growth.TSH and 17 α-hydroxylase levels in CH twins and normal twins,with or without discordant growth,were compared.Chi-square and non-parametric statistics were performed for data analysis.Results The incidence of CH in twin neonates was 0.56％ (19/3 444),higher than that in singleton neonates [0.09％ (203/225 712),x2=76.225,P＜0.01].Among nineteen CH twins,CH occurred in both twins in eight cases (four twins) and in one of the twins in eleven cases.The gestational age at birth in the eight CH twins were less than 37 weeks,with four males and four females;five were low birth weight infants;one twin were dichorionic,and three twins were monochorionic.In the eleven cases of CH occurring in one of the twins,the gestational age was less than 37 weeks in nine cases,eight were low birth weight infants,six were male and five female;seven were monochorionic and four were dichoronic twins.Five cases of temporary hypothyroidism were all low birth weight infants among the growth-discordant twins.CH cases in growth-discordant group had lower birth weight than their normal twins [M(P25-P75),2 100 (1 800-2 600) vs 2 770 (2 530-2 960) g,Z=4.369],and a higher TSH level [15.4 (11.8-18.5) vs 6.4 (4.8-7.9) mU/L,Z=6.339] (both P＜0.05).In normal twins with or without discordant growth,the neonates with a lower birth weight had a higher TSH level [3.6(2.5-4.7) vs 2.4(1.8-2.9) mU/L,Z=0.962] in weight consistent group,compared with 6.0(4.4-7.8) vs 3.4(1.9-4.1) mU/L in weight inconsistent group (Z=4.369),both P＜0.05.Conclusions In the growth-discordant twins,neonates with a lower birth weight have a higher TSH level and a higher risk of temporary hypothyroidism.

Objective To analysis and summary the chromosome abnormal existing in old pregnant women from 2002 to 2013,and to provide basis for clinicians intervene the fetus with chromosome disorders.Methods The 4 539 pregnant women in Ningbo city from 2002 August to 2013 October accepted the fetal karyo type detection,were retrospective analyzed,the frequency of abnormal chromosomal karyotypes was calculated according to different age groups,and the pregnancy outcomes of the old pregnant women were followed up.Thechi-square testswere performed on the frequency dateof the abnormal chromosome karyotype,polymorphism,and serum screening of high risk for fetal chromosome detection of less than 35-years-old pregnant women.Results The total of advanced maternal age pregnancyduring the past 11 years in Ningbo City is 32 080,and the follow-up rate was 99.90％,there are 10 infants borned with chromosomal abnormalities,the 1 290 caseswere detected withadverse pregnancy.A total of 4 539 advanced maternal age pregnancyaccepted amniocentesis,in those we found 107 cases of chromosome abnormality fetus,116 cases of polymorphism.A total of 5 232 high-risk pregnant women accepted the serum screening in the same period (less than 35 years old),finding 135 cases of fetal chromosome abnormal and 69 cases of polymorphism.Conclusion To strengthen the prenatal diagnosis,especially for puerperae above the age of 39,will lower the birth rate of infants with chromosome disease and will be conducive to the high quality of population in Ningbo.

Objective To investigate rational management for pregnant women with intermediate risk of Down syndrome (DS) through a retrospective analysis of second trimester maternal screening results for DS.Methods Second-trimester triple maternal serum screening for DS was performed.High risk ( ≥ 1/270) pregnant women received prenatal diagnosis.Intermediate (1/1000 to 1/270) and low (＜1/1000) risk pregnant women received routine obstetric examination.Data of ultrasound diagnosis,karyotype analysis of amniotic fluid and postpartum follow-up were collected.Outcomes of pregnant women were retrospectively analyzed.The incidences of DS among three groups were compared.Data of different groups were compared with Fisher exact or Chi-square test.Results Eighty-six thousand eight hundred and seventy-four pregnant women accepted maternal serum screening and outcomes of 86 126 cases were followed up,among which 4342 cases were DS high risk,8196 intermediate and 73 588 low risk.The incidence of DS was 6.22‰(27/4342) for high risk,0.73 ‰ (6/8196) for intermediate risk and 0.04 ‰ (3/73 588) for low risk group.The incidence of DS was higher in high risk group than in intermediate risk group (Fisher exact probability,P=0.000),and was higher in intermediate risk group than in low risk group (Fisher exact probability,P=0.000).Comparison among the three subgroups within intermediate risk group showed no significant differences (x2 =0.047,P =0.977).Conclusions Pregnant women with intermediate risk of DS should be paid more attention.Reasonable management such as ultrasound diagnosis and prenatal consultation should be provided.

SD rats were injected with streptozotocin and fed with high fat diet,used as type 2 diabetic model. Transcription factor Fox01 [in nucleus (15.00±1. 15 vs 6.45±0. 62) %, P<0.05], Caspase-3 [(23.73 ±1.48 vs 6.30±2.20)% ,P<0.01] expressions in pancreatic istet β cells and the positive rate of islet β cells apoptosis[(22.29±1.84 vs 6.25±2.42) %, P<0.01] in diabetic rats were higher than those of control rats. The islet cells which highly expresed Fox01 (in nucleus)and caspase-3 were just the apoptotic islet cells. Therefore,Fox01 may be involved in regulating apoptosis of islet β cells in type 2 diabetes.

Objective To examine the role of p38MAPK in high glucose-induced apoptosis of osteoblast MC3T3-E1 cell line, and to investigate its effect on the expressions of apoptosis-related molecules including caspase3, bax, and bcl-2. Methods The lentiviral vector containing short hairpin RNA targeting p38MAPK was constructed. The cultured osteoblast MC3T3-E1 cell were divided into 5 groups:normal control group(A group), high glucose group(B group), p38MAPK-shRNA transfection group(C group), signal transduction inhibitor group(D group), and transfection with negative control siRNA group(E group). RT-PCR was used to determine the p38MAPK mRNA expression levels in MC3T3-E1 cells. Flow cytometry(FCM)was employed to detect the cell apoptotic percentage. The protein levels of apoptosis-related molecules p38MAPK, p-p38MAPK, caspase-3, bax, and bcl-2 were assayed by Western blot. Ultrastructural alternation of MC3T3-E1 cell was observed under transmission electron microscopy(TEM). Results The lentiviral vector containing short hairp in RNA targeting p38MAPK was successfully constructed and transfected into MC3T3-E1 cells. RT-PCR result suggested that the siRNA targeting p38MAPK could effectively reduce the p38MAPK mRNA expression level induced by high glucose in MC3T3-E1 cell line. FCM showed siRNA significantly decreased high glucose-induced apoptosis percentage of MC3T3-E1 cells(P＜0.01). Meanwhile, we also found the siRNA significantly attenuated the proteins levels of p38MAPK, p-p38MAPK, caspase-3, and gene bax induced by high glucose in MC3T3-E1 cells, whereas the protein level of gene bcl-2 was enhanced remarkably when compared with high glucose group and negative control siRNA group(P＜0.01, P＜0.05).Conclusion The iRNA targeting p38MAPK suppressed high glucose-induced MC3T3-E1 cell apoptosis via inhibiting the activation of p38MAPK signaling pathway, thereby reducing the expressions levels of p-p38MAPK, caspase-3 and gene bax, and up-regulating the level of gene bcl-2.
