Chinese Journal of Primary Medicine and Pharmacy 2012;19(9):1343-1344
Objective To explore the effect of different treatments for breast cancer patients.Methods The clinical date of 24 patients with breast cancer were retrospectively analyzed.According to treatment method,24 patients were divided into 2 groups,control group of 12 patients received,and vinorelbine plus cisplatin.Experimental group of 12 patients received gemcitabine plus cisplatin.Both groups were treated for 6 weeks,follow-up in JanuaryFebruary,after treatment the short-term efficacy and toxicity were observed.Results During follow-up compared betwween two groups,after 6 weeks of treatment in patients with overall response rate ( complete response + partial response) are better than 1 week after treatment,the difference was statistically significant( P <0.05 ) ;between the two groups compared after treatment,experimental group patients overall efficiency as better than the control group,but had no statistically significant difference( P > 0.05 ).In the control group,Ⅲ + Ⅳ leukopenia,nausea,vomiting and phlebitis rate were relatively high than experimental group,experimental group Ⅲ +Ⅳ thrombocytopenia was higher than control group,the differences were statistically significant( P <0.05 ).Conclusion Early application of gemcitabine plus cisplatin in patients with breast cancer could significantly improve,the survival and prognosis,improve patients quality of life,and safe,it's worthy of promoting in clinic.
2.Study on the clinical effect and the influence to coagulation factor of carboprost tromethamine on the treatment of the patients with postpartum hemorrhage
Chinese Journal of Biochemical Pharmaceutics 2017;37(8):267-269
Objective To investigate the clinical effect and the influence to coagulation factor of carboprost tromethamine on the treatment of the patients with postpartum hemorrhage. Methods 60 pregnant women with placenta previa complicated with postpartum hemorrhage from May 2016 to March 2017 were randomly divided into the control group (n=30) and the observation group (n=30). The control group were given oxytocin, the observation group were received carboprost tromethamine. Fibrinogen (FIB), prothrombin time (APTT), prothrombin time (PT) and platelet count before and after surgery in the two groups were analyzed by CA7000 automatic blood analyzer. The effect and coagulation indexes in the two groups were compared. Results The clinical curative rate in the observation group was 96.67% and 93.33% in the control group, the differences had no statistically significant. The amount of hemorrhage in postpartum 2h and 24h and the hemoglobin in postpartum 24h in the observation group were less than those in the control group (P<0.05); There was no significant difference about coagulation indexes between the 2 groups before treatment;The platelet count, PT and APTT levels in the observation group were lower than those in the control group, and the level of FIB was higher than that in the control group (P<0.05); The incidence of adverse reaction was 6.67% in the observation group and 10% in the control group, the difference was not statistically significant. Conclusion Choosing carboprost tromethamine to treat placenta prevail complicated with postpartum hemorrhage has a good curative effect, which is helpful to reduce the amount of postpartum hemorrhage and improve the coagulation indexes, so it is worth popularizing

Chinese Journal of Ultrasonography 2012;21(6):466-469
ObjectiveTo analyze the systolic function of subendocardial myocardium of the left ventricle in patients with diabetes mellitus (DM) and DM associated hypertension by speckle tracking imaging (STI).Methods The left ventricular ejection fraction(LVEF) and left ventricular mass index (LVMI) of all subjects including 30 patients with diabetes mellitus(DM group),25 patients with DM associated hypertension (DH group) and 30 healthy volunteers (control group) were normal and near.The common parameters of echocardiogram were measured and the peak systolic longitudinal strain of subendocardial myocardium were analyzed from the long-axis view at the levels of mitral annulus,papillary muscle and apex by STI.All above parameters were compared among three groups.ResultsNo significant difference in all parameters was found between the control group and two patient groups,but the ratio of E/A was significantly lower in the two patient groups than that of control group ( P <0.01).The peak systolic longitudinal strain of some segments were significantly lower in the two patient groups than that of control group ( P <0.01).The peak systolic longitudinal strain of the subendocardial myocardium of all segments in the two patient groups were different decrease compared with the control group( P <0.01 or P < 0.001).The peak systolic longitudinal strain of the subendocardial myocardium of the DH group except some segments were decrease compared with the DM group ( P <0.01).ConclusionsSTI may be early used to identify the left ventricular systolic function in patients with diabetes mellitus.

8.THE CHANGE IN FLOW DISTRIBUTION AND THE EFFECT OF POLYGONUM CUSPID ATUM ON RAT MICROVASCULATURE DURING HEMORRHAGIC SHOCK
Medical Journal of Chinese People's Liberation Army 1981;0(06):-
The flow distribution of leukocytes in the microvasculature of rat skeletal muscle during hemorrhagic shock was measured by Microcirculation Image Multiple Parameters Computer Analysis System (MIMPCAS). It was found that the change of leukocyte flow distribution had taken place in V3 during hemorrhagic shock as follows: central axial-flowing leukocytes moved slowly, marginated to the vessel wall then started to roll along the wall, and stuck to the endothelium at last. During transfusion blood flow became faster, sticking leukocytes were rushed out to be rolling along the vessel wall and accelerated to enter the central stream. Total leukocyte -endothelium contact time (TLECT), which is a quantitative index for leukocyte endothelium interaction, is calculated, and it was found that TLECT was prolonged in shock state. The results show that it is not enough to increase blood pressure and shear stress to liberate sticking leukocytes, and it is necessary to search for a new approach to decrease the adhesive force between leukocyte and endothelium. Polygonum cuspidatum may not only increase wall shear rate but also decrease the adhesive force.
10.Progresses in Mitogen-activated Protein Kinase-activated Protein Kinases
Progress in Biochemistry and Biophysics 2006;0(07):-
Mitogen-activated protein kinase (MAPK) signaling pathways are involved in multiple important cellular responses. To activate their downstream protein kinases by phosphorylation is a crucial manner for MAPK family members to fulfill their physiological functions. Downstream of MAPKs, there exist three structurally related MAPK-activated protein kinases (MAPKAPKs or MKs), i.e., MK2, MK3 and MK5. Once upon activated by MAPKs, MKs signal to different cellular targets, to regulate gene expression at the levels of transcription and translation, control cytoskeleton remodelling and cell cycle, and mediate cell migration and embryonic development. Recently, based on the gene knockout studies, the function divisions among different MK subfamily members are gradually clear, leading to tremendous advancements of our knowledge on MKs.
