Objective We sought to summarize the experience in nursing the patients of Robertsonian translocation receiving pre-implantation genetic diagnosis (PGD).Methods Thirty-eight patients with Robertsonian translocation received PGD.These patients received health education and psychological nursing except for routine therapy and nursing.Results All these patients had no obvious negative emotion and complied with the therapy.Nine patients were successfully pregnant and pregnancy rate was 23.7％,7 of them delivered healthy neonates.Conclusions Health education,psychology nursing together with controlled ovarian stimulation,egg retrieval and embryonic transplantation can reduce negative emotion,improve compliance of therapy,and benefit the process of PGD and clinical outcomes.

Objective To explore the relationship between serum placental growth factor (PLGF) and carotid atherosclerosis (CAS) in patients with type 2 diabetes mellitus (T2DM ). Methods Serum PLGF were determined by ELISA in 53 patients with T2DM ,who were divided into T2DM without carotid plague (T2DM group ,n= 27) and T2DM with carotid plague (T2DM + CAS group ,n= 26). Fasting plasma glucose (FPG) ,glycosylated hemoglobin A1c (HbA1c) and some other metabolic variables were also measured. The results were compared to those of 27 healthy controls (NC group). Results Serum PLGF levels were significantly higher in T2DM group and T2DM + CAS group than in NC group (P<0.01). T2DM+CAS group showed significantly higher serum levels of PLGF compared to that of T 2DM group(P<0.01).Correlation analysis showed that serum PLGF was positively correlated with TC ,LDL‐C , hsC‐RP and IL‐6 in T2DM patients (P<0.01). Similarly ,multiple regression analysis showed that LDL‐C and IL‐6 were the independent factors of serum PLGF level (P<0.05). Furthermore ,Serum PLGF was positively associated with carotid plague. Conclusion PLGF is positively related with chronic inflammation factors in T2DM patients. Serum PLGF may play an important role in the occurrence and development of carotid atherosclerosis and other macroangiopathy in T 2DM.

Objective To study the therapeutic effect of Danshen injection combined with conventional therapy on children with recurrent asthmatic bronchitis. Methods A prospective study was conducted. Fifty-five children with asthmatic bronchitis admitted in People's Hospital of Henan Province from January 2012 to July 2014 were enrolled and randomly divided into a integrative Chinese and western medicine group(30 cases)and a conventional therapy group(25 cases);in the same period,18 healthy children having passed physical examinations were chosen as the healthy control group. In the conventional therapy group,rest,oxygen inspiration,anti-infection, fluid supplement and aerosol inhalation,etc. were given,while in the integrative Chinese and western medicine group,based on the similar conventional therapies,additionally Danshen injection 0.4 mL · kg-1 · d-1 was given,once per day for a total of 14 days. The wheezing remission time and the pulmonary rale extinction time were observed in the two patient groups,and the fractional exhaled nitric oxide(FeNO)content was investigated in the three groups. Results The wheezing remission time and the pulmonary rale extinction time of the integrative Chinese and western medicine group were obviously shortened compared with those in the conventional therapy group〔the wheezing remission time(days):2.3±0.8 vs. 5.2±1.1,the pulmonary rale extinction time(days):6.8±1.5 vs. 8.4±1.1,both P<0.01〕. The contents of FeNO in the integrative Chinese and western medicine group and the conventional therapy group before treatment were significantly higher than those in the healthy control group(×10-9:30.3±9.5,30.4±8.2 vs. 13.6±3.4,both P<0.01),but after treatment the FeNO levels of both patient groups were markedly lowered,and the degree of change in integrative Chinese and western medicine group was more significant(×10-9:18.6±4.7 vs. 24.0±6.8,P<0.01). Conclusion Danshen injection combined with conventional therapy can obviously down-regulate the FeNO content,alleviate the airway inflammation,effectively relieve the children recurrence of asthmatic bronchitis.

Objective To investigate the effects of controlled hypotension induced with sodium nitroprusside (SNP) or nicardipine on hemodynamics during hip operation and postoperative hepatic and renal function.Methods Twenty ASA Ⅰ or Ⅱ patients aged 20-70 yrs weighing 50-80 kg scheduled for total hip replacement or open reduction and internal fixation of fracture of acetabulum were randomized to receive either SNP (group Ⅰ ) or nicardipine (group Ⅱ ) for induced hypotension during operation. Each group included 10 patients. Radial artery and right internal jugular vein were cannulated for BP and CVP monitoring. The probe of Hemo-Sonic ?100 esophageal supersonic hemodynamic monitor (Arrow U.S.A) was placed in the esophagus and fixed when best signal was obtained. ECG, hemodynamics including MAP, HR, CVP, CO and other parameters, SpO2 and PetCO2 were continuously monitored. Anesthesia was induced with propofol 2 mg?kg-1 , fentanyl 2-3 ?g? kg-1 and vecuronium 0.1 mg?kg-1 and maintained with 1.5% isoflurane and continuous infusion of propofol ( at 4-6 mg?kg-1 ?h-1 ) and intermittent i.v. boluses of vecuronium after tracheal intubation. MAP was reduced to 55-65 mm Hg with SNP (at a rate of 0.5-8.0 ?g?kg-1?min-1 ) or nicardipine (at 1.0-8.0 ?g?kg-1 ?min-1 ) . Intraoperative blood loss and blood transfusion and postoperative drainage from the wound were measured and recorded.Hemodynamic parameters were recorded before hypotension and 15, 30 and 60 min after start of induced hypotension and 15 and 30 min after recovery from hypotension. Hepatic and renal functions were measured before and after operation using total bilirubin, AST, ALT, BUN and creatinine. Results The two groups were comparable with respect to sex ratio (M/F) , age, height, body weight, duration of induced hypotension and operation. MAP and systemic vascular resistance (SVR) were significantly reduced and tachycardia developed during hypotension in both groups. The left ventricular ejection time was significantly prolonged and aortic blood flow (ABF) and cardiac output (CO) were significantly increased and CVP was lowered during hypotension as compared to the baseline values in SNP group. BUN was significantly reduced after operation ( P

BACKGROUND:Osteoporosis and its complications severely threaten the elder’s health. Simvastatin, widely accepted as a lipid-lowering drug, is reported to potentialy promote bone formation, but it is in debate when oraly administered, and there is no evidence to support whether this is due to the region difference.
OBJECTIVE:To investigate the effect of oraly administered simvastatin on bone mass and biomechanical properties of the femur and vertebrae in osteopenia rats induced by ovariectomy (OVX).
METHODS: Twenty-four 6-month-old female Sprague-Dawley rats were subjected to OVX+oraly administered saline vehicle (OVX group,n=8), OVX+oraly administered simvastatin (5 mg/kg/d; intervention group,n=8) or sham surgery (sham group,n=8). After 8 weeks of treatment, al rats were sacrificed and the level of procolagen type I N-terminal propeptide in blood serum was assessed by ELISA. Bone mineral density was determined in the L5 vertebra and left femur using dual-energy X-rays. Furthermore, the biomechanical properties of the L4 vertebra and right femur, including maximum load and elastic modulus, were detected by compression testing and three-point bending test, respectively.
RESULTS AND CONCLUSION: The serum level of procolagen type I N-terminal propeptide in the sham group was significantly lower than that in the other two groups. OVX rats showed significantly lower bone mineral density in both the L5 vertebra and left femur than sham rats (P < 0.05). Rats in the intervention group showed higher bone mineral density than those in the OVX group, with statisticaly significant difference in the L5 vertebra (P < 0.05), but insignificant difference in the femur. Maximum load and elastic modulus of the L4 vertebra in the OVX group were significantly lower than those in the sham and intervention group. Markedly lower elastic modulus of the femur was found in the OVX group than the sham and intervention groups. These findings demonstrate that simvastatin treatment can partialy prevent bone loss in OVX rats with more notable effect on the vertebrae than the femur, and for this model, the vertebra is superior to the femur used in biomechanical test.

Objective:To explore the hepatocyte insulin sensitivity of intrauterine growth retardation ( IUGR) rats and establish an insulin resistance cell model in vitro.Methods: An IUGR animal model was established by protein malnutrition during the mother pregnancy .On 60 d and 90 d after birth , the offspring rats were fasted for 12 hours and then their angular vein blood was collected to measure the fasting plasma glucose and fasting serum insulin level , then the insulin resistance index ( HOMA-IR) and insulin sensitivity index ( ISI) were calculated .The insulin sensitivity was evaluated by HOMA-IR and ISI.Primary hepatocytes from each group were respectively isolated by two-step perfusion with collage-nase and were defined as normal hepatocytes group and IUGR hepatocytes group .The normal hepatocyte group was divided into two groups: control group and insulin induction group .Insulin induction group was established by primary cultures of normal hepatocyte incubated with varying dilutions of insulin . CCK-8 was used to detect the viability of the cultured hepatocytes .Glucose oxidase-peroxidase method kit was used to measure glucose consumption of the hepatocytes .Results:HOMA-IR was significantly higher in IUGR rats than in the normal rats at the age of 60 days ( t=-17 .02 , P<0 .05 ) and 90 days ( t=-12.52, P<0.05).ISI was significantly lower than in the normal rats aged 60 days (t=5.61, P<0.05) and 90 days (t=12.42, P<0.05).There were no significant differences in hepatocyte viability among the control group , IUGR group and insulin induction group after incubation of 48 h on day 60 (F=1.34, P=0.29) and day 90 (F=0.22, P=0.81).The glucose consumption of the IUGR group and insulin induction group were significantly decreased compared with the control group on day 60 ( F=9.28, P=0.002) and day 90 (F=56.60, P<0.001), while there was no significant difference be-tween the IUGR group and insulin induction group (P=0.08, P=0.10).Conclusion:The insulin sen-sitivity of hepatocytes of IUGR rats decreased from adolescence to adulthood .High-dilution insulin may induce insulin resistance cell model in vitro.

Objective To investigate the roles of phosphatidylinositol 3-kinase/protein kinase B (PI3K/AKT) signaling pathway and its regulatory protein peroxisome proliferator-activated receptor γ (PPAR γ) and phosphatase and tension homologue deleted on chromosome 10 (PTEN) in regulating insulin sensitivity in rats with fetal growth restriction (FGR).Methods Sixteen pregnant rats were randomly divided into two groups including FGR and control groups on the 12th day of pregnancy (eight in each group).The FGR group was given low protein diet (8％ of casein) and restriction diet to establish the neonatal rat model of FGR.All maternal rats after delivery and newborn rats after weaning on 21 days after born were fed with normal diet.Each time blood samples were collected from eight newborn rats of each group to measure levels of fasting plasma glucose (FPG) and fasting insulin(FINS) at the time points of 21 days,two and four months after birth.Then insulin resistance index (IRI) and insulin sensitivity index (ISI) were calculated to evaluate insulin sensitivity.Expression of PI3K,AKT,PPAR γγ,PTEN and glucose transporters 4 (GLUT4) in skeletal muscle at mRNA and protein levels were measured at 21 days,two and four months after birth with real time fluorescence polymerase chain reaction and Western blot,respectively.Relationships between the expression of key molecules of PI3K/AKT signaling pathway and insulin sensitivity were analyzed.T-test,and Pearson's correlation analysis were used for statistical analysis.Results (1) The average birth weight of newborn rats in the FGR group was lower than that of the control group [(4.37± 0.69) vs (7.03±0.55) g,t=-20.75,P＜0.05].The incidence of FGR in the FGR group was 93.33％ (70/75).(2) Compared with normal offspring,those in the FGR group showed significantly increased FPG [two months after birth:(5.53± 0.58) vs (7.49 ± 0.38) mmol/L,t=8.08;four months afterbirth:(6.35±0.66) vs (8.94±0.90) mmol/L,t=6.58],FINS [two months afterbirth:(9.18±0.66) vs (14.67± 1.90) mU/L,t=7.71;four months after birth:(33.08±2.76) vs (56.33±2.81) mU/L,t=16.71] and IR1 (two months after birth:2.25±0.31 vs 4.90±0.81,t=8.63;four months after birth:9.30±0.90 vs 22.44±3.10,t=1 1.51),but decreased ISI (two months after birth:0.020 ± 0.002 vs 0.009± 0.001,t=-10.1 4;four months after birth:0.005±0.000 vs 0.002 ±0.000,t=-14.91) at two and four months after birth (all P＜0.05).(3) Compared with normal offspring,those in the FGR group showed decreased expression of PI3K (21 days after birth:0.082±0.028 vs 0.019±0.004,t=-6.29;two months after birth:0.020±0.003 vs 0.010±0.005,t=-4.78;four months after birth:0.014±0.004 vs 0.003±0.001,t=-7.87) and GLUT4 (21 days after birth:0.132±0.057 vs 0.041 ±0.019,t=-4.32;two months after birth:0.183±0.084 vs 0.069±0.017,t=-3.74;four months after birth:0.248±0.069 vs 0.113±0.040,t=-4.74) at mRNA level at 21 days,two and four months after birth (all P＜0.05).Compared with normal offspring,decreased expression of PPAR γ (two months after birth:0.028±0.002 vs 0.012±0.005,t=-3.70;four months after birth:0.030±0.008 vs 0.012±0.005,t=-3.80) and increased expression of PTEN (two months after birth:0.020±0.004 vs 0.045±0.014,t=5.09;four months after birth:0.023±0.007 vs 0.034±0.009,t=2.57) at mRNA level were observed in offspring of the FGR group at two and four months after birth (all P＜0.05).(4) Compared with normal offspring,expression of PI3K protein (21 days after birth:0.22±0.01 vs 0.17±0.02,t=-6.62;two months after birth:0.27±0.03 vs 0.16±0.02,t=-7.25;four months after birth:0.18±0.01 vs 0.09±0.02,t=-9.79) and GLUT4 protein (21 days after birth:0.21 ±0.01 vs 0.03±0.01,t=-27.29;two months after birth:0.10±0.01 vs 0.06t±0.01,t=-3.90;four months after birth:0.13 ±0.01 vs 0.08± 0.02,t=-8.10) decreased in offspring in the FGR group at 21 days,two and four months after birth (all P＜0.05).Compared with normal offspring,those in the FGR group showed decreased expression of PPAR γ protein (two months after birth:0.10 ± 0.01 vs 0.07± 0.01,t =-7.29;four months after birth:0.09±0.01 vs 0.08±0.01,t=-2.83),but increased expression of PTEN at protein level (two months after birth:0.10±0.01 vs 0.15±0.02,t=6.01;four months after birth:0.09±±0.01 vs 0.13±0.02,t=5.51) at two and four months after birth (all P＜0.05).(5) The IRI levels in offsprings in the FGR group were negatively correlated with the expression of PI3K,GLUT4 and PPAR γ at protein level (two months after birth:r=-0.90,-0.92 and-0.79;four months after birth:r=-0.92,-0.75 and-0.73,all P＜0.05),but positively correlated with the expression of PTEN at protein level (r=0.87 and 0.86,both P＜0.05) at two and four months after birth.Conclusions The abnormal expression of the key molecules of PI3K/AKT signaling pathway precedes the decrease of insulin sensitivity in newborn rats with FGR and the expression regulatory protein PPAR γ and PTEN are also changed,suggesting that these molecules may induce the impairment of insulin sensitivity in rats with FGR and be involved in the development of insulin resistance.
