OBJECTIVE:To improve the electronic prescription prior-review mode and increase the rate of qualified prescrip-tions. METHODS:The electronic prescription prior-review mode of our hospital was established by setting up outpatient and emer-gency electronic prescription review team,review evidence and enforcement measures. Aimed at these problems as low review effi-ciency at initial stage,non-unified standards and untimely feedback,quality control circle and internet tools WeChat were used to improve the mode and evaluate its effects. RESULTS:The electronic prescription prior-review mode of our hospital was improved by optimizing system settings,unifying review standard,one-to-one feedback and communication with WeChat public platform, etc. Average time of prescription prior-review had reduced from 50 s to 30.58 s;the rate of qualified prescriptions had increased from 86.77% to 95.30%;prescription review efficiency and the rate of qualified prescriptions had been improved significantly. CONCLUSIONS:The implementation and continuous improvement of electronic prescription prior-review mode can reduce the rate of unqualified prescriptions and promote rational drug use in outpatient and emergency department.

AIM To investigate the protective effect of polydatin on ischemia-reperfusion (I-R) injury in cardiac muscle and the possible mechanism. METHODS Langendorff technique was used to make I-R injury in rats. Male Sprague-Dawley rats were randomly divided into control, model, polydatin(25, 50 and 75 μmol·L-1), glibenclamide(Gli, 10 μmol·L-1)+polydatin(50 μmol·L-1), 5-hydroxydecanoate(5-HD, 100 μmol·L-1)+polydatin(50 μmol·L-1), and atractyloside (Atr, 20 μmol·L-1)+polydatin(50 μmol·L-1) groups. The hearts in control group were perfused with K-H solution for 110 min. Model group hearts were subjected to 30 min no-flow global ischemia followed by 60 min of reperfusion. The hearts in 3 polydatin groups were perfused with K-H solution containing different concentrations of polydatin for 10 min before I-R. The hearts in Gli+polydatin and 5-HD+polydatin groups were perfused with K-H solution containing Gli or 5-HD for 5 min firstly, then perfused with K-H solution containing both polydatin and Gli or 5-HD for 10 min before I-R. The hearts in Atr+polydatin group were perfused with K-H solution containing polydatin for 10 min before I-R and perfused with K-H solution containing Atr for 15 min after I-R. The cardiac function, including left ventricular end-diastolic pressure (LVEDP), left ventricular developed pressure (LVDP), the maximal rates of rise and decline of left ventricular pressure (±dp/dtmax), and coronary flow (CF), were recorded before, after 30 min no-flow global ischemia and, during 60 min reperfusion. Myocardial infarct size was assessed using 2, 3, 5-triphenyltetrazolium chloride method and myocardial ultrastructure was observed via transmission electron microscope after 60 min reperfusion. RESULTS There were no significant differences in cardiac functional parameters between control and model groups in pre-ischemia condition. Compared with model group, polydatin promoted a better recovery of cardiac function after I-R in a concentration-dependent manner. After 60 min of reperfusion, the values of LVDP, ±dp/dtmax and CF in polydatin groups were much higher, but LVEDP was lower than those in model group. Polydatin (50 μmol·L-1) also significantly reduced myocardial infarct size and relieved the I-R injury of myocardial ultrastructure. The protective effects of polydatin (50 μmol·L-1) on LVDP, LVEDP, ±dp/dtmax and CF, as well as the inhibitory effect on infarct size after I-R were abolished by Gli, 5-HD and Atr. CONCLUSION Polydatin has protective effect against I-R injury in rat hearts, which may be related with the opening of ATP-sensitive potassium channel located in both cell membrane and mitochondrial membrane, as well as inhibition of mitochondrial permeability transition pore opening.

Follicle-stimulating hormone (FSH) is synthesized and secreted by the anterior pituitary, which binds to its receptors expressed on the membrane of Sertoli cells in the testis to bring about spermatogenesis. With the development of DNA sequencing technology, FSH SNPs rs10835638 and FSHR SNPs rs6165, rs6166, and rs1394205 were detected, which might directly affect the expression of FSH and activity of FSHR, resulting in male spermatogenic dysfunction. This review focuses on the relationship of FSH and FSHR gene polymorphisms with male infertility.

Objective To detect the expression of metastasis sappressor 1(MTSS1) gene in cervical cancer tissue and to clarify its association with cervical cancer.Methods Totally 103 cases of cervical tissue were collected between Dec 2011 and Dec 2014 and classified according to biopsy and stage .Q-PCR and Western blotting were used to detect the expression of MTSS1 in normal cervical tissue and in different clinical stages of cervical cancer tissue .Results The expression of MTSS1 inⅡB-Ⅳstages of cervical cancer tissue was significantly higher than that of normal tissue or Ⅰ-ⅡA stages through q-PCR (P=0.000).Western blotting results showed that MTSS1 was positively expressed in normal cervical tissue at a rate of 23.3% or 53.3% in cervical cancer tissue.Moreover, the expression of MTSS1 was poorly correlated with age, tumor differentiation and lymphnode metastasis in cervical cancer tissue (P>0.05).The protein level of MTSS1 expressed in ⅡB-Ⅳ stages was significantly higher than that ofⅠ-ⅡA stages(P=0.005).Conclusion The expression of MTSS1 indicates the clinical stage of cervical cancer , suggesting that MTSS1 may play an important role in the development of cervical cancer .

OBJECTIVE To study the molecular mechanism of cisplatin(DDP)by which HeLa cell growth and proliferation are inhibited. METHODS Cultured HeLa cells were treated with DDP 0.02-75 μmol · L-1 for 24 or 48 h. CCK-8 assay was used to determine the cell proliferation. The wound scratch assay was used to detect the cell migration and invasion. Flow cytometry was used to detect the cell cycle arresting. q-PCR was used to test the expression of metastasis suppressor gene 1 (MTSS1)mRNA. Western blot was used to determine protein levels of MTSS1,phosphorylated-extra?cellular signal-regulated kinase(p-ERK) and phosphorylated-serine-threonine kinase(p-AKT). RESULTS Following the treatment with DDP for 24 or 48 h,the proliferation of HeLa cells was inhibited significantly (P<0.05),the value of the half inhibitory concentration (IC50) of cells was 4.14 and 11.82 μmol · L-1. Migration and invasion activity of HeLa cells were reduced according to the wound scratch assay(P<0.05). Flow cytometry results showed that the cell cycle was arrested at S phase. q-PCR results showed that MTSS1 mRNA expression changed with DDP in a concentration-dependent manner (r24 h=-0.965,P<0.01;r48 h=-0.953,P<0.01). Western blot showed that the protein levels of MTSS1,p-ERK and p-AKT expression declined significantly with the increase in DDP concentrations(p-ERK:r24 h=-0.875,P<0.01;r48 h=-0.966,P<0.01. p-AKT:r24 h=-0.831,P<0.01;r48 h=-0.863,P<0.01. MTSS1:r24 h=-0.969,P<0.01;r48 h=-0.988,P<0.01). CONCLUSION DDP treatment inhibits HeLa growth and proliferation by interfering with the MTSS1 expression and disturbing the activation of ERK and AKT signaling pathways.
