Objective To promote rational drug use by investigating quality of the outpatient and emergency prescriptions in the hospital .Methods We statistically summarized the evaluations of prescriptions and analyzed the drug use from January to Novem-ber ,2012 .Results The outpatient and emergency prescriptions were compliant to relevant writing standards ,without missing i-tems .The inaptitude of prescriptions were mainly in forms of inappropriate indication ,usage ,and dosage of drug and menstruum . The irrational prescriptions accounted for 5 .5% of those evaluated .Conclusion Rational drug use has been basically ensured through implementation of prescription evaluations and interventions .Irrational prescriptions exist in relatively small scale and are to be eliminated .

Isocitrate dehydrogenases(IDHs)are considered as key enzymes in the tricarboxylic acid cycle. Recurrent mutations in the IDH1 and IDH2 genes are recently found in several human cancers. Those point mutations specifically affect IDH1 and IDH2 active site arginine residues and confer a neomorphic enzyme function of directly catalyzing α-ketoglutarate(α-KG)to R-2-hydroxyglutarate(R-2-HG). R-2-HG can com-petitively inhibits α-KG-dependent enzymes and may therefore contribute to the occurrence and development of tumor. In addition,Mutation status of IDH1 and IDH2 are closely relative to the progress and prognosis of cer-tain tumor. Thus IDH1 and IDH2 are considered to be promising biomarkers for early diagnosis and prognosis and targeted therapy.

Objective To determine the effectivity of 5-azacytidine(5-Aza) inducing the cardiomyogenic SCs were isolated and purified from Sprague-Dawley (SD) rats. Some BMSCs were induced with 5-Aza,group Ⅰ was not induced with 5-Aza and the third generation of cells were used for the next experiment; group Ⅱ were cultured and induced with 5-Aza( 10 μmol/L) at the third day of the culture for 24 h; group Ⅲ were induced with 5-Aza( 10 μmol/L) for 24 h when the third generation of cell were fused; group Ⅳ were induced with 5-Aza( 10 μmol/L) for 24h at the third day of primary cuhure,which were induced with 5-Aza( 10 μmol/L) for 24 h before the third gener-phosis was found in the BMSCs among groups. CD34 was negatively expressed and CD29 and CD44 were positively gle 5-Aza inducing group(group Ⅲ ) was much higher than that in no 5-Aza inducing group( group Ⅰ ) [ MHC : (6. 82±2.05 ) % vs (3.61±1.14) % ], cTnI: (5.63±1.86) % vs (2.76±0.82) %, P < 0.05 ], but was significantly lower than the percentage in the double 5-Aza inducing group ( group Ⅳ ) [ MHC : ( 12.18±3.16) % vs ( 6.82±2. 05)% ] ,cTni:(9.93±2.79)% vs(5.63±1.86)% ,P<0.05]. Conclusions 5-Aza could promote the cardio-myogenic differentiation of BMSCs in a "Cardiac-like" Milieu. 5-Aza double induing is better than the single indu-cing.

OBJECTIVE To study the molecular mechanism of the drug-resistance of Gram-negative bacilli to the third generation of cephalosporins.METHODS MICs of 13 ?-lactams to the eleven Gram-negative bacilli clinical isolates were detected with the standard agar dilution technique.K-B disc confirmatory method was conducted to determine the ESBLs phenotype of the eleven isolates.The ESBLs encoding genes were analyzed by using PCR.RESULTS The eleven isolates were all resistant to the third generation of cephalosporins(MIC≥64 ?g/ml).Disk confirmatory test showed that 10 isolates produced ESBLs.The hydrolytic activity of the ESBLs from the 10 isolates to cefoperazone and cefamandole was very high.However,the hydrolytic activity of the ESBLs from the 10 isolates to ceftazidime was very low.CONCLUSIONS The enzyme activities and the genes of extended-spectrum ?-lactamases from 10 Gram-negative bacilli clinical isolates are preliminarily analyzed.These results provide the basis for further study on the molecular mechanism of the drug-resistence of Gram-negative bacilli.

AIM: To explored the treatment effects of retinal laser photocoagulation and the applications of color Doppler flow imaging(CDFI) in the diabetic retinopathy.METHODS: We collected 60 patients(120 eyes) with diabetic retinopathy(Ⅲ~Ⅳstage) from February 2013 to February 2014 in Anyang Eye Hospital admitted in fundus disease department.The health control (HC) group of 55 normal people was established simultaneously.Ocular blood flow velocity of the 55 normal people (110 eyes) and the 60 patients (120 eyes) was examined by CDFI of central retinal artery (CRA) and posterior ciliary artery (PCAs) using the PHILIPS HD6.Peak systolic velocity(PSV) was recorded.The examinations of CDFI, electroretinogram(ERG) and the vision were performed in pre-operation, 1,7d, 1, 3 and 6mo postoperatively.RESULTS: Compared the PSV of CRA of the DR group before and after photocoagulation to the data of the HC group, there was a significant difference(P<0.05);compared the PSV of CRA of the DR group after photocoagulation with the data before, there was a significant difference(P<0.05).Compared the PSV of PCAs of the DR group before and after photocoagulation to the data of the HC group, there was a significant difference(P<0.05);compared the PSV of PCAs of the DR group after photocoagulation with the data before, there was a significant difference at 1d postoperatively(P<0.05), there was no significant difference at 7d, 1, 3 and 6mo(P>0.05).Compared the aA and bA of ERG of the DR group before and after photocoagulation to the data of the HC group, there was a significant difference(P<0.05).Compared the aA and bA of ERG of the DR group after photocoagulation with the data before, there was a significant difference(P<0.05).Compared the aT and bT of ERG of the DR group before and after photocoagulation to the data of the HC group, there was a significant difference(P<0.05);compared the aT and bT of ERG of the group DR after photocoagulation with the data before, there was no significant difference(P>0.05).The vision of 49 cases(98 eyes) was improved 1 to 3 rows, the effective rate was 82%.The vision of 11 cases(22 eyes) remained constant.CONCLUSION: Retinal laser photocoagulation is an effective treatment to diabetic retinopathy patients, which can significantly reduce the peak systolic velocity of the central retinal artery, improve and stabilize the condition, protect visual function in long-term clinical effect.Color doppler flow imaging can observe the changes of ocular vessel flow velocity in diabetic` eyes noninvasively, repeatedly and in real time, providing a basis for clinical treatments.

The most common forms of treatment for amblyopia are occlusion therapy and pharmacologic penalization. But these methods can not recover all the visual deficits of amblyopes and there are some disadvantages of the treatment which need to be considered, including adverse effects, compliance and social stigma. Recently, some novel approaches are investigated for improving the effectiveness and compliance of treatment for amblyopia.

microRNAs (miRNAs) are short non-protein-coding RNAs,which play important roles in the cell proliferation,differentiation,apoptosis,as well as activation of oncogenic and antioncogenic signals.Researches show that the abnormal expressions of miRNAs are closely related to the tumorigenesis,histological type,diagnosis,treatment and prognosis of lung cancer.So miRNAs may be the most potential and promising therapeutic targets for lung cancer.

Objective To analysis the long-term retention rate of Levetiraceram (LEV) monotherapy or combination therapy of infant epilepsy. Methods The clinical data of patients with infant epilepsy treated by LEV had been retrospectively analyzed from July 2006 to June 2007. Results Sixty patients with infant epilepsy treated by LEV had been recruited, 20 cases with partial seizures, 19 cases with generalized seizures, 21 cases with epilepsy syndrome. Among them 21 cases was intractable epilepsy. The retention rates of LEV in 6-month, 1-year, 2-year, 3-year and 4-year were 95.5%, 75.0%, 60.0%, 51.7%, and 38.3%. The most common reason for withdrawal was lack of effect (43.2%). COX regression model suggested that duration>1 month (RR=2.91, 95%CI:1.16~7.30) and refractory epilepsy (RR=2.30, 95%CI:1.22~4.32) were risk factors of withdrawal (all P<0.05). After treatment, the seizure frequency signiifcantly reduced compared with baseline (P<0.01). To the end of the follow-up, the efifciency was 100%and the complete remission rate was 69.57%in 23 cases continued treatment. The main side effect were fatigue (56.0%), and sleep increased, irritability, and so on. Conclusions LEV monotherapy or combination therapy has well long-term retention rate, maintains well efifcacy and tolerability in infant epilepsy.
