Objective To evaluate diagnosis of cord entanglem ent and fetus safety by B ultra-sonic and nemodromometer. Methods 86 pregnant women were diagnosed as cord entanglement in late pregnancy by B ultrasonic examination and Doppler blood flow analysis of the S/D ratio from ma r to May, 1999. The pregnancy outcomes were followed up. Cord entanglement,es -pecially the high blood circulating resistance, suggested that there was h igh risk of fetal distress. The obstetrician would manage the delivery stage pro perly according to the results of Doppler examination.Results 7 2 women were proved cord entanglement after delivery wity coincident rate of 83. 7%. Five women were delivered by cesarean section and forceps among 11 cases of abno rmal S/D ratio, and the rate of operative delivery in group with abnormalS/D rat io was significantly higher than that of the group with normal S/D ratio (P ＜0.05). Conclusions The combined examination can improve the rate of diagnosis of cord entanglement and abnormal S/D ratio, forecast the feta l distress, reduce birth rate of infant with lower Apgar score and reduce the ces arean section rate due to social factor.

Objective To understand the expressions of transforming growth factor ?1(TGF-?1) and its receptors(T?R) in villi and decidua during early pregnancy and their effects on early embryo development, and explore the mechanism of spontaneous abortion. Methods By immunohistochemical technique, expressions of TGF-?1 and its receptors were determined in villi and decidua from 10 cases of spontaneous abortion women after in vitro fertilization and embryo transfer (IVF-ET group), 20 cases of spontaneous abortion women (spontaneous abortion group), and 20 cases of normal early pregnancy women (control group). Results TGF-?1 and its receptors had high expressions in decidua cells, villus glands and interstitial cytoplasm in all three groups. The average light density of the expressions of TGF-?1 in the villi and decidua of IVF-ET, spontaneous abortion and control groups were 0.167 and 0.199, 0.198 and 0.201, 0.277 and 0.274, respectively. The intensity of T?R-Ⅰ in the villi and decidua of IVF-ET, spontaneous abortion and control groups were 0.144 and 0.150, 0.202 and 0.201, 0.238 and 0.281, respectively. And the expressions of T?R-Ⅱ in the villi and decidua of IVF-ET, spontaneous abortion and control groups were 0.199 and 0.145, 0.153 and 0.156, 0.300 and 0.301, respectively. The differences between the control group and both abortion groups were all significant (P

Objective To investigate pregnancy complications,cesarean delivery and abnormal fetal presentation in women with uterine anomalies.Methods Fifty women diagnosed with uterine malformation and sixty women with normal uterus were retrospectively analyzed .Results The group comprised women with uterine malformation had significantly higher stillbirth or fetal death (P <0.05) and lower rates of the full-term delivery(P <0.05) than that of the control group.The subgroup comprised women with uterine anomalies had significantly higher rates of cesare -an section(P <0.05) and abnormal fetal position(P <0.05) than the control group.The birth weight and length of infant in observation group were significantly lower than those in control group (P <0.05).The rate of placenta abnormalities in uterine anomalies was significantly higher than that in control group (P <0.05).The incidences of premature rupture of membrane,cord entanglement,oligohydramnios,postpartum hemorrhage and neonatal asphyxia in observation group were no significant difference than those in control group .The rate of premature rupture of membrane(PROM) in uterus unicornis was significantly higher than that in other types (P <0.05).Conclusion Compared with women with normal uterus ,the incidences of abnormal fetal position ,the placenta abnormalities,pre-mature delivery,and stillbirth or fetal death in women with congenital uterine anomalies are high .Uterine anomalies are associated with a decrease in the birth weight and length .We should pay more attention to finding the uterine malformation and treatment before pregnancy .Antenatal care should be reinforced in pregnancy women with uterine anomalies.

Objective: To study the antihyperglycemic effect of flavonoids from seed (FSH) and fruit(FFH) of Hippophae rhamnoides L.on diabetic rats induced by streptozotocin (STZ). Methods: The STZ-induced diabetic rats were randomly divided into four groups and were given intragastrically (ig) water, metformin, FSH and FFH respectively once a day. After four weeks, the levels of serum glucose, fructosamine, lipid, protein, GSH and lactic acid (LD) were assayed. Results: FSH could reduce the levels of serum glucose, fructosamine and triglyceride significantly, increase the contents of serum total protein and albumin obviously, enhance the ability of antioxidation in STZ-induced diabetic rats. FSH also could decrease food and water intake of diabetic rats evidently. But FSH had little effect on LD, LDH, glycogen and body weight in diabetic rats. FFH was not as good as FSH. Conclusion: FSH is antihyperglycemic , and can improve the metabolic derangements of STZ- induced diabetic rats.

AIM:To investigate the effects of high plasma triglyceride (TG) caused by apolipoprotein C Ⅲ( ApoC Ⅲ) transgene on the occurrence and development of abdominal aortic aneurysm ( AAA) .METHODS:The animal models of hypercholesterolemia and hypercholesterolemia combined with hypertriglyceridemia were established by feeding high-fat diet to LDLR-/-and ApoC Ⅲ+LDLR-/-mice, respectively.AAA was induced in these mice by pancreatic elastase. By evaluating the incidence of AAA, relative maximal abdominal aortic diameter, disruption of the elastic lamellar structure and expression of matrix metalloproteinases ( MMPs) in the aorta walls of the AAA, the occurrence and development of AAA were compared in LDLR-/-and ApoC Ⅲ+LDLR-/-mice fed with either chow diet or high-fat diet.In addition, an in vitro TNF-α-induced aneurysmal microenvironment model on vascular smooth muscle cells ( VSMC) was used to study the impact of triglyceride-rich lipoproteins ( TRLs) from mice with normal or high contents of ApoCⅢon elastin protein expres-sion.RESULTS:Feeding the high-fat diet aggravated the severity of AAA in the LDLR-/-mice.ApoC Ⅲ+LDLR-/-mice fed with high-fat diet had less severe AAA than LDLR-/-mice fed with high-fat diet.TRLs inhibited degradation of VSMC elas-tin protein induced by TNF-α, and in vitro TRLs from the mice with high content of ApoC Ⅲ, compared to those with nor-mal content of ApoC Ⅲ, had better inhibitory effect on the degradation of elastin.CONCLUSION:High plasma TG caused by ApoC Ⅲtransgene alleviates AAA of the LDLR-/-mice induced by elastase and high-fat diet.The effect is probably attrib-uted to the hypertriglyceridemia caused by ApoC Ⅲtransgene.

0bjectlve To examine the metaphase II spindle and chromosome configurations of human oocytes cultured for different times after thawing.MethodsUsing slow.cooling and raid—thawing protocol combined with 0.3 mol/L sucrose and 1.5 mol/L 1,2-propanedio 1(1,2-PROH)to cryoprotect human mature oocytes(n=102),the 64 survival oocytes without abnormal zona pellucida and cytoskeletal were randomly assigned to three groups after thawing:group A:culture 1 hour(n=20),group B:culture 3 hour(n=22),group C:culture 5 hours(n=22),the flesh oocytes served as control group(n=18).Immunocytochefifical staining and fluorescence microscopy were used to assess the morphology of the metaphase II spindle and chromosome.Results(1)The normal spindle rates of groups A,B and C were 10％(2/20),46％(10/22)and 41％(9/22)respectively,significantly decreased compared with control group(83％,15/18;P<0.05).The rates of absent spindle in group A(45％,9/20)was significantly higher than control group(6％,1/18;P<0.01).Also,the rates of absent spindle in group A was higher than groups B(14％,3/20)and C(14％,3/20;P<0.05).However,no significant differences were observed in groups B and C(P>0.05).(2)A significant increase in abnormal chromosome rate was observed in group A(30％,6/20)compared to groups B(68％,15/22),C(64％,14/22)and control group(78％,14/18;尸<0.05).No differences in chromosome morphology were observed in groups B,C and control group(P>0.05).Conclusions The cryoproteetant protocol leads to a deleterious effect on the organization of the meiotic spindle and chromosome at MI stage.The 3—5 hours post—thawing incubation could permit restoration of the meiotic spindles and chromosome.

Objective To evaluate the association between recurrent miscarriages and insulin resistance.Methods The case-control studies on the association between recurrent spontaneous abortion and insulin resistance from June 1996 to April 2012 were collected from Medline,Elsevier,Chinese Journal Fulltext Database,Chinese Biological Medicine Database,data base of Wanfang,Springer link and EMBASE.RevMan 5.1 software was used for Meta analysis.Results According to the included criteria,7 clinical trials were finally selected.Total 467 cases with recurrent pregnancy loss were enrolled in study group,while 413 women with no history of abnormal pregnancies were enrolled in control group.No significant difference was found in average age and body mass index between the two groups (P ＞ 0.05).Meta analysis results showed that the level of fasting glucose was no statistical difference between study group and control group (WMD =2.27,95％ CI:-1.11 to 5.65,P ＞0.05); fasting insulin level was higher 2.05 mU/L in study group than that of in control group,the difference was statistically significant (WMD =2.05,95％ CI:1.03 to 3.08,P ＜ 0.01).Case number of study group on Homa-insulin resistance ＞ 4.5 was more than that of control group (OR =3.36,95％ CI:1.72 to 6.57,P ＜ 0.01).Case number of study group on glucose/insulin ratio ＜ 4.5 was more than that of the control group,statistical difference was found (OR =3.37,95％ CI:1.90 to 5.99,P ＜ 0.01).Conclusion Insulin resistance is associated with the susceptibility to recurrent miscarriages,and it may contribute to the occurrence of recurrent miscarriages.
