Cytomegalovirus (CMV),a DNA herpusvirusesw,is the most common virus leading to intrauterine infetcion.It is transmitted from mother to fetus through placenta,and the neonates who suffering from congenital symptomatic infections may have sensorineural hearing loss,hepatosplenomegaly,microcephaly,chorioretinitis etc.Studies have suggested that the characters of infections on pregnant women,such as the time of infection,the serological results and virus load in amniotic fluid are associated with the outcome of offsprings.This paper is to review the risk of CMV infections on women at childbearing age,screening of CMV infections on pregnant women and the prenatal diagonosis of fetal CMV infection.

BACKGROUND:Diabetes mel itus after kidney transplantation is an important metabolic complication of the transplanted organ, and seriously affects the quality of life and long-term survival rate of patients, which is a risk factor for renal al ograft dysfunction and cardiovascular disease. OBJECTIVE:To investigate the changes in fasting blood glucose and prognosis of patients who had survived more than 1 year after renal transplantation. METHODS:Total y 42 patients undergoing renal transplantation admitted at Xiantao First People’s Hospital from January 2003 to January 2013, including 7 cases of preoperative diabetes, 11 cases of impaired fasting glucose and 24 cases of normal fasting blood glucose. Fasting blood glucose levels were detected at 1, 7, 14 days and 1, 3, 6, 12 months after renal transplantation, and the survival conditions were also compared among different groups. Cox proportional hazard model was used to analyze influential factors of survival in patients undergoing renal transplantation. RESULTS AND CONCLUSION:The fasting blood glucose levels in the diabetes mel itus group were significantly higher than those in the impaired fasting glucose group and normal fasting blood glucose group before and after renal transplantation (P<0.05). The fasting blood glucose levels were increased in al the groups at 1 day after transplantation (P<0.05), and stabilized at 3 months after transplantation. The survival rate was significantly higher in the normal fasting blood glucose group than in the diabetes mel itus and impaired fasting glucose groups after renal transplantation (P<0.05). Cox proportional hazard model analysis showed that preoperative fasting blood glucose, age, postoperative tumor and infection were the independent risk factors for death in patients undergoing renal transplantation, among which, postoperative tumor led to the highest death risk ratio that was 2.376. Taken together, preoperative diabetes mel itus has some impacts on renal recipients who survive more than 1 year fol owing transplantation, but postoperative diabetes mel itus had no influence on the survival rate of the patients.

AKI is one of the frequent complications of critically ill patients,which is associated with high mortality.RRT is the main treatment,especially CRRT nowadays.But the optimal dosage of CRRT is unclear.In this article,we will review the evidence of CRRT in critically ill patients with AKI.Compared with traditional dosage of CRRT,high dose CRRT did not improve the clinical outcome.There was no difference in mortality rate,time for renal recovery,ICU hospitalization time,or organ failure in both groups,while there were more complications including hypokalemia and hypophosphatemia in the high dose CRRT group.Treatment with high dose CRRT could alter drug metabolism,cause malnutrition,unbalance the electrolyzes and cause hypothermia.So we conclude that traditional dosage of CRRT[20～35 mL/(kg?h)]is applicable for critically ill patients with AKI,but the determination of optimal dose depends on many clinical situations other than clearance of small solutes.

[Objective] To observe the effect of electroacupuncture (EA) on learning and cerebral heme oxygenase (HO) activity in rats with vascular dementia (VD). [Methods] Sixty rats were randomly allocated to mimic group (Group A), EA group (Group B), nimotone group (Group C) and model group (Group D) . Rat models of VD were established by 4 - vessel occulusion (4 - VO) method. Ten days after modeling, Group B was trested with EA on Baihui (GV20) and Dazhui (GV14), one time per day; Group C with nimotone, 20ml/kg body weight, ig, qd. The treatment course lasted 15 days. And then the learning was estimated with Morris water maze and HO activity in cortex and hippocampus (HC) of rats was also measured. [Results] Mean escape latency within 6 days in EA group was shorter than that in model group ( P 0.05). In EA group, the swimming times in the original platform quadrant were more than that in the right, left or opposite quadrant and also more than that in the original platform quadrant in the model group (P

Objective:To research the effect of total saponins Panax ginseng (TSPG) on the drug resistance of human erythroleukemia drug resistant cell line K562/A02 and its mechanism.Methods:The sensitivity of TSPG-treated K562/A02 cells to anticancer drugs was determined by MTT assay.Immunohistochemistry method was used to measure mdr-1 gene product P-gp and apoptosis regulation gene product bcl-2 expression. RT-PCR technique was used to examine mdr-1 mRNA expression.Results:In non-toxic dosages, TSPG strengthened the toxicity effect of doxorubicin on K562/A02 cells, while the reversing effect of TSPG was related to its concentration. Decrease in P-gp expression in K562/A02 cells was marked ( P O. 05)after 3 days of TSPG(150?g/ml)treatment.Decrease in mdr-1 mRNA expression was significant ( P

Objective To analyze the effect of Smad7 on the expression of TGF-?R,R Smads and STRAP in the process of malignant transformation of immortalized human bronchial epithelial cells BEP2D.Methods Cells were cultured and protein were extracted from BEP2D,BERP35T2,BS7 and RS7 cells,then Western blotting was performed to examine the expression level of TGF-?RⅠ,TGF-?RⅡ,Smad2/3,Smad4 and STRAP.(Results) Stable transfection of Smad7 gene led to decreased expression of TGF-?RⅡ and increased expression of Smad2 and STRAP in both BEP2D and BERP35T2 cells.There were no changes in the expression of Smad3 and Smad4.Conclusion Overexpression of Smad7 leads to decreased expression of TGF-?R Ⅱ and increased expression of STRAP in BEP2D and BERP35T2 cells,which could be one of the mechanisms of the malignant transformation of BEP2D cells.

Objective:To investigate the neuroprotective role of hemin and its effect on the expression of neuroglobin in the hippocampal organotypic tissue cultures(HOTC)after combined oxygen/glucose deprivation(OGD).Methods:SD rats,8~10-days old,were sacri-ficed for brain.HOTC were made and randomly divided into three groups:HOTC,HOTC undergoing OGD(OGD),HOTC under- going OGD following pretreatment with hemin(Hemin+OGD). The expression of neuroglobin was detected by immunohisto-chemical technique and computer-assisted image analysis.Results:In OGD group,hippocampal organotypic tissue lost normal structure and neurons were damaged severely.Pretreatment with hemin could effectively reverse the damage of the neurons.The expression of neu- roglobin in the Hemin+OGD group were significantly stronger than that in the OGD group.Conclusion:Hemin has protective effect on injury induced by OGD in rat hippaocampal slices,which is associated with enhanced expression of neuroglobin.
