An investigation of sphygmogram was carried out on 52 patients with middle type hypertensive syndrome and some normal women in late pregnancy were as the control. Their pregnancies were measured by a sphygmogram and the influence of pregnant hypertensive syndrome on the cardio-vas-cular system analyzed. It was found that left ventricular systolic force, cardial power and left ventricular effective work constant were stronger than those of the control. Meanwhile, myocardial energy invert constant decreased. This reflected the patients has compensative function in spite of increased myocardic load. In addition, pressure of peripheral arteries, blood volume of the patients, resistance and elasticmodulus of the artery were higher than those of the control, but capillary blood flow velocity decreased. Consequently, we have realized more about hemodynamic changes of hypertensive syndrome in pregnancy. And the authors consider that the sphygmogram may be used to detect changes of the cardio-vascular system of the patients with prcgancy toxemia and that the mean arterial pressure by a sphygmogram may reflect changes of hemodynamics better and earlier than a traditional sphygmomanometer. The sphygmogram may be used to make an early diagnosis of hypertensive syndrome.

Objective To compare the efficacy of acrossing the injured vertebra percutaneous pedicle screw fixation and traditional open surgery for Magerl A thoracolumbar fractures.Methods Retrospective analysis 56 patients with single segmental Magerl A thoracolumbar fractures without neurological symptoms were stabilized,including percutaneous fixation in 26 cases and open fixation in 30 cases.The operation time,intraoperative,blood loss,incision length,sagittal Cobb angle,height of injured vertebral,VAS,ODI,were compared between 2 groups.Results The precutaneous group less surgical blood loss,incision length and postoperative go to the fields time than the open group (P ＜ 0.05).There were improvements in Cobb angle and anterior height in two groups (P ＜ 0.05).The precutaneous group had lower VAS and ODI scores postoperation (P ＜ 0.05).The fracture vertebral front height and Cobb angle had significantly loss at final follow up than on the third day postoperation (P ＜ 0.05).Conclusions The percutaneous pedicle screw fixation can achieve similar effect in the treatment of Magerl A thoracolumbar fractures without neurological symptoms than open surgery,with less iatrogenic injury,less intraoperative blood loss and quick recovery for patients.

Objective To investigate the effects of Liraglutide on plasma FGF-21 level in patients with type 2 diabetes mellitus (T2DM). Methods Enzyme linked immunosorbent assay (ELISA) was used to measure plasma FGF-21 level in patients with T2DM and normal controls (NGT). Relationship between plasma FGF-21level and BMI, WHR, HOMA-IR, HOMA-IS, FFA was analyzed. After Liraglutide treatment, plasma FGF-21level was observed in patients with T2DM. Results Fasting plasma FGF-21 level was higher in T2DM patients than that in normal control group ( 1.81 ±0.32 vs. 1.32 ±0.09 μg/L, P ＜0.01 ). After Liraglutide treatment, WHR, BMI, FPG, 2hPBG, HbA1c and FFA in T2DM patients significantly decreased ( P ＜0.05 or P ＜0. 01 ),HOMA-IS remarkably increased (P ＜ 0. 01 ), and FGF-21 had no change. Conclusion Liraglutide and FGF-21may have different roles in insulin resistance.

Objective To analysis the incidence and management of monozygotic twin (MZT) conceived by assisted reproductive techniques (ART). Methods A retrospective analysis of clinical pregnancies and MZT that resulted from ART was performed in Reproductive Medical Center,the First Affiliated Hospital,Wenzhou Medical University between January 2011 and January 2014. Results A total of 5 908 pregnancies were diagnosed: 2 012 twins, 157 high-order multiple pregnancy (HOMP), including 4 quadruplets. Overall, 51 MZT pregnancies were identified of them including 32 cases HOMP and 19 cases MZT. The incidence of MZT resulting from cleavage-stage embryo transfer was similar to blastocyst transfer (P=0.960). The percent of MZT resulting from in vitro fertilization [0.93% (28/3 022)], frozen-thawed embryo transfer [0.87% (13/1 502)] and intracytoplamic sperm injection [0.72% (10/1 384)] did not show statistical significance (P=0.794). The expectantly managed MZT was associated with a significantly greater likelihood of miscarriage [6/19 vs 5.11% (101/1 976)], and low birth weight infant [73.91% (17/23) vs 42.89% (1 453/3 388), P<0.01], when compared with dizygotic twin (DZT) did not undergo selective embryo reduction(SER). In monozygotic (MZ)-triplets with SER to 2 fetuses or to 1 fetus, there was no cases of preterm birth or low birth weight infant observed in MZ-triplets with SER to 1 fetus;when compared with MZ-triplets with SER to 2 fetuses, the low birth weight infant [56.00% (14/25), P=0.021] has statistical significance. The likelihood of the survival of two babies was lower in MZ-triplets with SER to 2 fetuses when compared with non-MZ triplets with SER to 2 fetuses [42.86%(9/21)vs 75.21%(91/121), P=0.003]. Conclusions The incidence of MZT pregnancies following ART is high. It plays a significant role in the occurrence of HOMP. MZT pregnancies are at an increased risk of adverse outcomes , it should transform to a single embryo thansfer (SET) program to reduce them incideuce. Reduction of MZT contained in multiple pregnancies appears to be a safe option.

Objective To investigate the relationship between bed rest time and development of prethrombotic state in the elderly patients with hip fracture.Methods One hundred and sixty-six patients who stayed in bed after hip fracture,aged ≥65 yr,were divided into 5 groups according to the bed rest time on admission to hospital:bed rest time ＜ 24 h (Ⅰ group,n =61),bed rest time 24-48 h (Ⅱ group,n =29),bed rest time 3-6days (Ⅲ group,n =29),bed rest time 7-14 days (Ⅳ group,n =34),and bed rest time ＞ 14 days (Ⅴ group,n =13).Venous blood samples were collected to measure the platelet count,coagulation function,and concentrations of plasma D-Dimer and serum α-granule membrane protein 140 (GMP-140).The development of abnormality in each index was recorded.The development of deep vein thrombosis in both lower extremities was diagnosed using color Doppler ultrasound in D-Dimer-positive patients.Results Compared with group Ⅰ,the abnormal rate of fibrinogen (Fib) and D-Dimer and serum GMP-140 concentrations were significantly increased in Ⅱ and Ⅲ groups,the abnormal rate of platelet count,Fib and D-Dimer and serum GMP-140 concentrations were increased in lⅣ group,and the abnormal rate of platelet count was increased,and no significant change was found in the serum GMP-140 concentrations and abnormal rate of Fib and D-Dimer in Ⅴ group.Compared with group Ⅱ,the serum GMP-140 concentrations were significantly increased in Ⅲ and Ⅳ groups,the abnormal rate of Fib and D-Dimer was increased in Ⅳ group,and no significant change was found in the abnormal rate of Fib and DDimer in Ⅲ group.The abnormal rate of platelet count was significantly lower in Ⅳ group than in Ⅲ group.Color Doppler Ultrasonography showed no sign of deep vein thrombosis.Conclusion For the elderly patients with hip fracture,the possibility of pre-thrombotic state developed is increased when the bed rest time is more than 24 h,and the patients were classified as high-risk patients when the bed rest time is more than 3 days.

Objective To investigate the inhibitory effect of four and a half LIM protein 2(FHL2) on inhibitor of differentiation 1(Id1)-mediated suppression of transcriptional regulation activity and Id1-promoted invasive growth of human breast cancer cells MCF-7.Methods The effect of FHL2 on Id1-mediated transcriptional repression in MCF-7 cells was determined by cotransfection and relative biluciferase assay.The cell proliferation was determined by MTT assay,and the invasive capacity of MCF-7 cells was determined by Transwell assay.Results The transcriptional repression effect of Id1 on basic helix-loop-helix(bHLH) factor E47-mediated transcription activity in MCF-7 cells,and Id1-promoted proliferation and invasive growth of MCF-7 cells were significantly suppressed by FHL2.Conclusion FHL2 can inhibit the proliferation and invasive growth of human breast cancer cells via repressing Id1-mediated functional activity.The results provide a basis for further investigating the functional roles of FHL2-Id1 signal pathway in the carcinogenesis and development of human breast cancer.

Objective To investigate clinical effect of in vitro maturation(IVM)of immature oocytes transferred from conventional in vitro fertilization embryo transfer(IVF-ET) cycles.Methods From January 2008 to June 2009.medical documents of 155 infertile patients underwent IVF-ET in the Reproductive Medical Center of Fimt Affiliated Hospital of Wenzhou Medical College were analyzed retrospectively.If more than 20 oocytes were monitored after 5-7 days of ovulation induction or follicular developmental retardation were confirmed after 8-13 days of ovulation induction.according to patients' wish,IVM were transferred in 60 cycles(group A).In the mean time.IVF was continued in 95 cycles (group B).The mean dosage of gonadotropin,the cancel lation rate of cycles,the mean numbers of oocytes retrieved and maturation,the rate of fertilization and excellent quality embryos.pregnancy outcome and the incidence rate of ovarian hyperstimulation syndrome(OHSS)were compared and analyzed.Results The rates of embryo transfer were 92%(55/60)in group A and 63%(60/95)in group B,which showed significant differences (P<0.05).In group A,the mean dosage of the gonadotropin,the mean number of oocytes retrieved,the cleavage rate and OHSS rate were(1030±468)U,10±6,82.2%(231/281)and O,and were(1544±338)U,14±4,94.0%(502/534)and 35%(21/60)in group B,respectively,all data abeve exhibited statistieal difference between two groups(P<0.05).However,the rates of fertilization and excellent quality embryos had no significant differences between two groups(P>0.05).In group A,the rate of clinical pregnancy per transfer was 53%(29/55)and multiple pregnancy was 14%(4/29),and were 47%(28/60) and 32%(9/28)in group B,they all had no significant differences (P>0.05).Conclusion IVM of immature oocytes used in conventional IVF cycles not only obtained a high clinical pregnancy rate,but also reduced gonadotropin using dosage and avoided OHSS completely.

Objective To analyze risk factors for metabolic syndrome in Mongolia versus Han nationalities in Xilinhaote city. Methods Using the epidemiology investigation data of health examination,we calculated the prevalence of metabolic syndrome of Mongolia and Han nationalities, then used logistic regression model to explore risk factors of two nationalities. Results The crude prevalence of MS in Mongolia and Han nationality was 34.3%and 24.6% respectively. The multivariate logistic regression showed that male, the meat-rich diets and aging(OR:2.18, 1.92, 1.04 respectively)were the risk factors for Mongolia nationality, and smoking, family history of hypertension, drinking, the meat-rich diets, aging(OR:1.89, 1.84, 1.72, 1.61 and 1.04 respectively)were the risk factors for Han nationality. Conclusions Xinlinhaote population has higher MS prevalence, and different nationalities have different risk factors. We should take preventive actions to control it.

Objective To compare the laboratory and clinical results between unstimulated in vitro maturation (IVM) and IVM converted from in vitro fertilization (IVF) in polycystic ovarian syndrome (PCOS) and non-PCOS patients.Methods We divided 591 IVM cycles in the First Affiliated Hospital of Wenzhou Medical Univesity from Jan.2008 to Dec.2013 into 4 groups:group A1B1,PCOS patients underwent unstimulated IVM protocol,240 cycles; group A1B2,PCOS patients underwent IVM converted from conventional stimulated IVF protocol,153 cycles; group A2B1,non-PCOS patients underwent unstimutlated IVM protocol,103 cycles; group A2B2,non-PCOS patient underwent IVM converted from conventional stimulated IVF protocol,95 cycles.Multiple linear regression method and binary logistic regression method were used to assess the influence of PCOS and protocols for IVM on laboratory and clinical outcomes.Results The mean number of oocytes retrieved was positively related with PCOS [partial regression coefficient (B)=3.37,P＜0.01].The maturation rate of oocytes was positively related with hCG-prime prior to oocyte aspiration (B=0.05,P=0.010).High-quality embryo rate was positively related with PCOS and IVM converted from IVF (B=0.08,P=0.010; B=0.09,P=0.001),as well as implantation rate related with them (B=0.07,P=0.010; B=0.10,P＜0.01).PCOS and IVM converted from IVF improved hCG positive (hCG＞10 U/L) rate (OR=1.636,95％CI:1.113-2.204,P＜0.05; OR=1.861,95％CI:1.307-2.649,P＜0.05) and the clinical pregnancy rate (OR=1.507,95％CI:1.041-2.240,P＜0.05; OR=1.881,95％CI:1.312-2.696,P＜0.05).IVM converted from IVF protocol decreased the spontaneous abortion rate (OR=0.490,95％CI:0.245-0.978,P＜0.05).Multiple gestation rate and ectopic pregnancy rate were not affected by PCOS condition and protocol used (P＞0.05).Conclusions PCOS and IVM converted from IVF protocol improved the high-quality embryo rate,implantation rate,hCG positive rate and clinical pregnancy rate.IVM converted from IVF protocol reduced the spontaneous abortion rate.PCOS patients may be more suitable for the IVM treatment.No matter PCOS or non-PCOS patients,IVM converted from IVF protocol had better pregnancy outcome than that of unstimulated cycle.

AIM: To evaluate the effect of GYY4137, a novel hydrogen sulfide (H2S) donor, on cytosolic lipid decomposition in mouse primary steatosis hepatocytes.METHODS: Oleic acid (OA) was used to induce hepatic steatosis model in vitro.The C57BL/6 mouse primary hepatocytes isolated and cultured by 2-step in situ perfusion were divided into 4 groups: the cells in control group were incubated with normal medium for 54 h;the cells in model group were incubated with OA at 1.2 mmol/L for 48 h followed by serum-free phenol red-free RPMI-1640 for 6 h;the cells in H2S group or DL-propar-gylglycine (PAG;an inhibitor of cystathione γ-lysase, inhibiting H2S synthesis) group were incubated with OA at 1.2 mmol/L for 48 h followed by serum-free phenol red-free RPMI-1640 which contained 1 mmol/L GYY4137 or 200 μmol/L PAG for 6 h.The glycerin release and the protein expression of hormone-sensitive lipase (HSL) in the cells were mea-sured.RESULTS: Compared with model group, the glycerin release and the protein expression of phosphorylated HSL (p-HSL) in H2S group decreased significantly, while those increased significantly in PAG group.CONCLUSION: In steatosis hepatocytes, exogenous H2S possibly decreases cytosolic lipid decomposition by decreasing the protein level of p-HSL.
