Objective To analysis newborn stage and long-term physiological and neuropsychological development in children born after assisted reproductive technology(ART),and to evaluate the safety of ART.Methods Eighty-four 6-month-old to 6-year-old children born after ART performed from January 1st,2006 to June 30th,2011 in Reproduction Center of Fuzhou General Hospital were taken as ART group; and 84 matched children born after spontaneous conception were as control group.The physiological and neuropsychological states of these children in their newborn stage and 6-month-old to 6-year-old duration were compared with Chi-square or t test.Results There was no statistical difference in childbearing age of mothers,the prevalence of gestational diabetes mellitus and hypcrtensive disorder complicating pregnancy,delivery mode,living environment,parents' education level,newborn birth length,birth weight,the rate of premature birth,low birth weight,asphyxia and hospitalized to neonatal intensive care unit between two groups (P＞0.05).In ART group,the incidence of growth retardation and abnormal social life skills was 6.0 ％ (5/84) and 1.2 ％ (1/84),and no statistical difference were found comparing with control guoup [4.8％(4/84) and 1.2％(1/84),x2 =0.12 and 0.00,P＞0.05],neither the developmental quotient (95.9±6.1 vs 94.8±5.1,t=1.25,P=0.21).Twins had higher rates of preterm birth [41.8％ (33/79) vs 10.1％(9/89),x2 =22.37,OR=6.38,95％CI:2.81-14.50,P=0.00],low birth weight [51.9％(41/79) vs 6.7％(6/89),x2=42.35,OR=14.93,95％ CI:5.84-38.16,P=0.00],asphyxia [10.1 ％ (8/79) vs 1.1 ％(1/89),x2 =6.69,OR=9.92,95％ CI:1.21～81.15,P=0.01],hospitalized to neonatal intensive care unit [36.7 ％ (29/79) vs 14.6 ％ (13/89),x2 =10.90,OR =3.39,95％CI:1.61-7.14,P=0.00] and growth retardation [11.4％(9/79) vs 0.0％(0/89),x2=10.71,RR=0.11,P=0.00] than singleton.Conclusions ART has no negative effects on children's physical and neuropsychological development.It could increase the incidence of twins,so that it might increase the incidences of preterm labor and low birth weight,which might affect the long-term physical and neuropsychological development of the offspring.

AIM: To investigate the effect of GSTP1 over-expression on the sensitivity of human hepatoma HepG2 cells to oxaliplatin (OXA).METHODS: Adenovirus carrying GSTP1 (Ad-GSTP1) was used to infect HepG2 cells for establishing the cell line over-expressing GSTP1.The cells were randomly divided into 6 groups: control, vehicle, Ad-GSTP1, OXA, OXA +vehicle and OXA +Ad-GSTP1.The cell survival rates were examined by CCK-8 assay, and the apoptotic rates were analyzed by flow cytometry.The protein levels of GSTP1, Akt, mTOR, p-Akt and p-mTOR were deter-mined by Western blot.RESULTS: OXA decreased the cell survival rate in a dose-dependent manner (P <0.05).The protein expression of GSTP1 increased after transfection with adenovirus.At basal level, up-regulation of GSTP1 signifi-cantly decreased the cell survival rate, increased the cell apoptosis, and inhibited the phosphorylation levels of Akt and mTOR (P <0.05).Moreover, GSTP1 over-expression enhanced the effect of OXA on the cell viability, cell apoptosis, and further inhibited the phosphorylation levels of Akt and mTOR ( P <0.05).CONCLUSION: Over-expression of GSTP1 augments the enhanced effect of OXA on HepG2 cell apoptosis, which may be related to the inactivation of Akt/mTOR signaling pathway.

Objective To investigate the anterior trans-injured vertebral short segment limited fixation and fusion in treating thoracic and lumbar spinal tuberculosis.Methods One hundred and three patients with spinal tuberculosis from 2010 to 2012 were operated by trans-anterior approach(trans-thoracic above thoracic spine 12,trans-retroperitoneal below waist spine 1)tuberculosis focus clearance and spinal canal decompression,intervertebral bone graft of vertebral structure,and short segment internal fixation for residual disease spine.Results The nerve function of the patients was effectively improved after surgery,and the imaging re-sults showed that the average lesion kyphosis angle was significantly decreased(P <0.05).The postoperative follow-up found that the bone graft was fused after half a year,and the average local kyphosis angle was still 13°,which had no obvious change compared with that after operation.In addition,the internal fixation position had no looseness and fracture,the grafted bone had no displace-ment and detachment,the four limbs movement was normal without local percussion pain or tenderness.Conclusion The anterior trans-injured vertebral short segment limited fixation and fusion has the satisfactory short term clinical efficacy in the treatment of thoracic and lumbar spinal tuberculosis.

To study the function and mechanism of the NgR-Rhoa- Rock signal pathways which exists in the retinal ganglion cells apoptosis in diabetes mellitus (DM) rats.
● METHODS: Some healthy SD rats were operated by means of single intraperitoneal injection of 1%streptozotocin based on the standard of 50mg/ kg wight, after that the blood sugar value was greater than 16. 7mmol/ L as DM model, then randomly divided into 3 groups, each group was 10 rats. ln addition to take 10 healthy SD rats as control group. Four groups of rats were bilaterally eyeball intravitreal injection in turn with NgR-siRNA virus 10μ L (siRNA group), NgR-siRNA virus diluted 10μ L ( DM group), NgR - siRNA virus - negative -control solution 10μ L (siRNA blank group), NgR- siRNA virus diluted 10μ L ( normal control group ), and fed normally. During that time, some life indexes like blood glucose, body mass, etc. were measured and recorded. After 12wk, the expression of NgR and Rhoa, HE staining, and TUNNEL staining were detected by Western blot analysis.
● RESULTS: Western blot analysis: compared with normal control group, the expression of NgR and Rhoa in DM group and siRNA blank group increased significantly (P<0. 01), while siRNA group was no significant change (P > 0. 05); compared with DM group and siRNA blank group, the expression of those proteins significantly lowered in siRNA group. HE staining: compared with normal control group, some extent ganglion cells arranged disorder, irregular shape, spacing not consistent were all found in three groups of model rats;compared with DM group and siRNA blank group, there was some improvement in siRNA group of ganglion cells about the order and shape size. TUNEL staining:compared with normal control group, there were retinal ganglion cells apoptosis in all of three groups of model rats. Compared with DM group and siRNA blank group, the number of retinal ganglion cells apoptotic cells was less, and the shape of cells had improved significantly in siRNA group.
●CONCLUSlON: ln the DM phase, the expression of NgR and Rhoa were up - regulation, the condition of diabetic retinal ganglion cell apoptosis was improved after that the NgR-Rhoa-Rock signal pathways had been inhibited.

Objective To discuss the psychological behavior intervention methods on reducing the violence behavior of schizophrenia patients. Methods 120 schizophrenia patients were admitted from January to December, 2007 and randomly assigned into the behavior intervention group (group A), the psy-chological support group (group B), the health education group (group C) and the control group (group D) with 30 cases in each group. Group A received routine nursing plus behavior intervention, group B was giv-en routine nursing plus psychological support, group C adopted routine nursing plus health education, group D only received routine nursing. The intervention effect was evaluated with MOAS and the relapse rate of violence behavior went through statistics. Results After intervention, the scores of MOAS decreased sig-nificantly in group A, B, C and D compared with those before intervention. The reduction of MOAS scores in group A, B and C was significantly higher than that of group D, with the highest reduction score in group A and group B and C followed subsequently. The relapse rates of the violence behavior in group A, B and C were significantly lower than those of group D. Conclusions Routine nursing, health education, psycho-logical support and behavior intervention can all reduce and decrease the violence behavior and the inci-dence of the violence behavior, among which behavior intervention proves to be the most effective, and psy-chological support and health education go subsequently.

Farnesoid X receptor (FXR) belongs to the nuclear receptor superfamily. It is highly related to the formation of metabolic syndrome and the glucose homeostasis, and therefore represents an important drug target against metabolic diseases and diabetes. In recent years, great progress has been made in the agonists, antagonists, and crystal structures of FXR. The diverse FXR ligands and their structure-activity relationship are reviewed in this article. The advances in the crystal structures of FXR in complex with different ligands are also introduced.

Objective Increased renal mast cells have been found in significant correlation with clinicopathological features of diabetic nephropathy ( DN) .However, the exact pathological significance of mast cells still remained to be elucidated.As one of the most abundant serine proteases, tryptase is specifically expressed by mast cells.The study was to observe the expression of tryptase in the urine of patients with diabetic nephropathy and realize the pathological significance of urinary tryptase and renal mast cells in the development of diabetic nephropathy. Methods Urine samples from 103 patients with diabetic nephropathy who were hospitalized at the clinical unit of the nephrology centre of Jingling Hospital from January 2012 to June 2013 were collected.According to concentra-tion of urinary albumin excretion rate, the patients were conducted to early-stage DN group (microalbuminuria,n=10), middle-stage DN group (proteinuria stage, n=31) and end-stage DN group (renal insufficiency stage,n=62).Meanwhile, urine samples from 20 normal persons were taken as the normal control group.Tryptase level in each urine sample was measured by using an ELISA kit.The average tryptase levels were compared among different groups and the correlation between urinary tryptase level and clinical indices was analyzed. Results ①In most cases, tryptase was not detected in the urine samples from normal persons(0.7 ±1.4 ng/mg creati-nine).However, the urinary trypatse level increased significantly with the development of diabetic nephropathy (11.6 ±10.5 ng/mg creatinine for early stage, 29.7 ±19.2 ng/mg creatinine for middle stage, and 44.6 ±43.4 ng/mg creatinine for late stage group).②The urinary tryptase level was found in significant correlation with ser-um creatinine (r=0.325, P<0.01), serum cystatin C (r=0.391, P<0.01), serum urea nitrogen (r=0.27, P<0.01), 24 hour uri-nary protein (r=0.389, P<0.01), urine C3 (r=0.276, P<0.05), urine retinol-binding protein (r=0.365, P<0.01), urine lysozyme (r=0.461, P<0.01), urine N-acetyl-β-glucosaminidase level (r=0.568, P<0.01), urinary kidney injury molecule-1 (r=0.434, P<0.05) and interleukin-18 level (r=0.375, P<0.05).No significant correlation was found between urinary tryptase level and age, gender, fasting blood sugar, postprandial blood sugar, HbA1c, triglyceride, high density lipoprotein or low density lipo-protein. Conclusion Mast cells play an important role in the development of diabetic nephropathy and might be a novel and effective target for the treatment of DN.
