Objective Onto observe the curative effect of carboprost tromethamine injection combined with mifepristone on the treatment of the patients with risky placenta previa. Methods 66 cases with placenta previa during mid pregnancy from January 2016 to December 2016 in Dingbian county people's hospital were randomly divided into two groups, 33 cases in the control group and 33 cases in the observation group. All patients were received cesarean section and traditional treatments such as oxytocin and gauze filling. Hemostatic effect, prognosis and incidence of adverse reactions in the two groups were compared. Results The intraoperative bleeding volume, the amount of vaginal bleeding 2 hours after operation and the amount of vaginal bleeding 2 to 24 hours after operation in the observation group were less than those in the control group (P<0.05). The rate of postpartum hemorrhage, the rate of disseminated intravascular coagulation and the incidence of puerperal disease in the observation group were significantly less than those in the control group (P<0.05). The sanguinous lochia time and menstrual recovery time in the observation group were better than those in the control group (P<0.05). There was no significant difference in the rate of hysterectomy and adverse reactions between the two groups. Conclusion Carboprost Tromethamine Injection combined with mifepristone in the treatment of pernicious placenta previa can effectively reduce the bleeding rate and promote the rehabilitation of pregnant women. It is safe and has no obvious adverse reactions. It is worthy of clinical application.

Neuroblastoma(NB) is the most common extracranial solid malignant tumor in childhood,which has various clinical manifestations.Tumor metastasis or relapse is one of the major causes of death in patients with NB.At present,the treatments of NB are mainly concentrated on the surgery,chemotherapy,radiation therapy,myeloablative therapy and transplantation,tumor targeted therapy,etc.But the treatment of children with high-risk NB is still not optimistic.Studies have shown that multidmg resistance is a major impediment to the successful treatment of NB.Hence,it is of great significance to have a comprehensive understanding of the chemoresistance mechanisms to improve the survival rate of NB patients.This review discusses the chemoresistance mechanisms of NB in several respects.

Objective To investigate the effect of borneol on levels of monoamine neurotransmitters in the prefrontal cortex of rat after long-term continuous operations.Methods A rat model of long-term continuous operations were established by using a treadmill protocol.Then Borneol(0.4 g/kg,p.o.) was given to the rats after the operation,and their activity-rest behavior and active avoidance response were assessed.Two h later,the rats were sacrificed and the level of monoamine neurotransmitter in the prefrontal cortex was determined by high performance liquid chromatography combined with electrochemical detection(HPLC-ECD).Results After the administration of borneol,the activities of operational animals were increased markedly as compared with that of vehicle operational group.The operational rats after borneol application had less response time than the ones treated with vehicle(6.85?1.24) s in active avoidance response.The levels of monoamine neurotransmitters including noradrenaline,dopamine,and 5-serotonin in the prefrontal cortex were decreased after treadmill operation.While application of borneol made the levels of noradrenaline and 5-serotonin increased significantly as compared to operational group.Conclusion Borneol have a reversal effect on rat awake activity impairment after long-term continuous operations.And the arousal effects of borneol are associated with the increase of noradrenaline and 5-serotonin levels in the prefrontal cortex.

OATP1B3, a member of SLC superfamily, is specifically expressed on the sinusoidal membrane of hepatocytes and is considered to be important in hepatic drug elimination. The overexpression of OATP1B3 was found recently in tumor tissues such as prostate, colon, and pancreatic tumors. Sequence variations in SLCO1B3 gene, such as SNPs, have been described and a common haplotype consisting of 334T>G and 699G>A SNPs is related to altered transport characteristics of OATP1B3. OATP1B3 is of relevance to drug metabolism through affecting alteration of hepatic concentration of endo- and xenobiotic compounds that interact with nuclear receptors such as PXR and CAR, and thereby directly alter the extent of target gene transcription, including major CYP isoenzymes such as CYP3A4. This review will provide an overview of substrates and inhibitors of OATP1B3 and subsequently to assess the effect of genetic mutation on transport activity. The studies linking OATP1B3 with cancer clinical outcomes are also discussed in this review.

Objection To investigate the effects of etomidate on aorta isolated from IR rats, and explore its underlying endothelium-related mechanism(s). Methods The IR animal model was made by feeding rats with high fructose diet for 8 weeks. Aortic rings were isolated and suspended in a tissue bath, and tensions were recorded isometrically. The effects of etomidate on provoked contractions of the rings were assessed in absence or presence of potassium channel blockers or NO-synthase inhibitors. Results Etomidate-induced relaxation in IR rings was greater than NC rings. NG-nitro-L-arginine methyl ester (L-NAME) or glibenclamide (Gli) inhibit significantly etomidate-induced relaxation in IR rings, and the inhibition of Gli was disappeared in endothelial-denuded aortic rings. Conclusion Etomidate cause vasodilation in IR rat aortas by an endothelial-dependent and independent manner. Impaired NO- and KATP channel-mediated relaxation and etomidate-induced increased availability of may involve in endothelial-dependent relaxation of etomidate in IR rat aortas.

In recent years,with the further study of bone marrow mesenchymal stem cell (BMSC),using BMSC transplantation for the treatment of ischemic cerebrovascular disease has become a research hotspot.However,there are still considerable controversies in the mechanism of action,transplanting time,transplantation path,and specific marker.

In recent years,a lot of researches have shown microRNA (miRNA) involved in every link of epithelial-mesenchymal transition(EMT) regulation process through a variety of signaling pathways in tumor; even the same kind of miRNA plays significantly different roles in different tumors,inducing great significance to guide clinic.

Objective To assess the diagnostic value of cytokeratin 18 fragment M30 (CK18-M30) and Fas in patients with nonalcoholic fatty liver disease (NAFLD),especially nonalcoholic steatohepatitis (NASH).Methods Among 58 patients with NAFLD,36 patients with NAFLD received liver biopsy.According to NAFLD activity score (NAS) and liver fibrosis score,patients were divided into NASH group (24 cases) and non-NASH group (12 cases).And at the same period,15 healthy individuals were set as healthy control group.The serum level of CK18 M30 and Fas were measured with enzyme-linked immunosorbant assay (ELISA).Rank sum test was performed to analyze the differences in the level of CK18-M30 and Fas between groups.The diagnostic value of CK18 M30 and Fas were assessed by the receiver operating characteristic (ROC) curves.Results The level of serum CK18-M30 of NAFLD group was significantly higher than that of healthy control group (97.24 U/L (86.06 to 113.12 U/L) vs 78.41 U/L (74.29 to 80.76 U/L),Z=-4.206,P＜0.01)).The level of serum CK18-M30 of NASH group was higher than that of non-NASH group (111.06 U/L (94.30 to 142.68 U/L) vs 89.00 U/L (83.56 to 106.50 U/L),Z=-2.233,P＜0.05)).The area under the ROC curve (AUC) of CK18-M30 in the diagnosis of NASH was 0.73 (0.56,0.90),and the sensitivity and specificity of CK18-M30 in diagnosis of NASH was 79.2％ and 58.3％,respectively.The AUC of Fas in diagnosis of NASH was 0.58 (0.38,0.77),while the sensitivity and specificity of Fas in diagnosis of NASH was 54.2％ and 66.7 ％.The serum level of Fas increased in FAFLD group compared with healthy control group,and in NASH group compared with non-NASH group,however the differences were not signifincant (both P＞ 0.05).Conclusions The level of CK18-M30 has certain value in the diagnosis of NASH.The diagnostic value of Fas in NASH needs more samples in further study.
