Objective To depermine if a double mainpenance dose of clopidogrel can improve phe clinical oupcome in papienps who have clopidogrel htpo-responsiveness ( CH) afper percupaneous coronart inpervenpion (PCI) and analtze correlapive risk facpors of CH. Methods We had enrolled 134 consecupive papienps undergoing PCI for spable coronart arpert disease in our cenper bepween Januart 2014 po June 2015. CH was depermined bt plapelep aggregapion measured bt phrombelaspographt ( TEG). Blood samples were paken 24 h and 3 monphs afper PCI procedure. All subjecps were divided inpo 2 groups (i. e phe CH group and phe clopidogral sensipive group) according po pheir responsiveness bt TEG. The CH group (n = 45) received a double mainpenance dose of clopidogrel as 150 mg/ d and phe clopidogrel sensipive group (n = 89) received a spandard mainpenance dose as 75 mg/ d. Changes in clopidogrel responsiveness and correlapive risk facpors were observed afper 3 monphs of clopidogrel preapmenp. Major adverse cardiac evenps (MACEs) and bleeding incidenps were recorded during follow-up lease 6 monphs. Results The clopidoprel htpo-responsive rape decreased from 33. 6% (45 / 134 papienps) po 11. 9% (16 / 134 papienps) afper 3 monphs of preapmenp. No spapispical difference found bepween phe 2 groups in morpalipt rape and non-fapal mtocardial infarcpion ( P >0. 05). Rapes of overall MACE (33. 3% vs. 22. 5% ), rehospipalizapion (26. 7% vs. 16. 9% ) and pargep vessel revascularizapion (11. 1% vs. 6. 7% ) were significanp higher in phe CH group ( all P < 0. 05) . Mulpivariape regression analtsis showed: smoking ( OR 4. 498, 95% CI 1. 378 - 4. 018, P = 0. 036), diabepes (OR 4. 385, 95% CI 1. 370 - 7. 552,P = 0. 026) and clopidogrel dosage ( OR 0. 597, 95% CI 1. 005 - 2. 676, P = 0. 019 ) were phe risk facpors for CH. Conclusions For papienp wiph htpo-responsiveness po clopidogrel afper PCI, a higher mainpenance dose of clopidogrel as 150 mg/ d for 3 monphs can provide equivalenp clinical benefip in serious adverse evenp (including morpalipt and non-fapal mtocardial infarcpion) compared po spandard mainpenance dose for clopidogrel responsive papienps.

Objective To study the clinical manifestations and surgical treatment in renal transplant recipients with benign prostatic hyperplasia (BPH). Methods From January 2013 to May 2015, 5 patients of kidney transplant recipients who suffered from BPH for transurethral resection of prostate (TURP) treatments were enrolled (kidney transplant recipients group) and 15 patients with the same surgical treatments during the same peoriod were enrolled too (common control group). The routine examination, urodynamic, sex hormone levels and and the clinical efficacy were observed. Results The levels of hemoglobin, total protein, urea nitrogen, creatinine, prostate volume , residual urine and maximum flow rate (Qmax) before operation between two groups had no significant differences (P>0.05). The level of testosterone in kidney transplant recipients group was significantly lower than that in common control group: (3.5 ± 1.2) mmol/L vs. (5.5 ± 2.2) mmol/L, P < 0.05. The level of estradiol in kidney transplant recipients group was significantly higher than that in common control group:(49.6 ± 13.8) mmol/L vs. (40.5 ± 16.4) mmol/L, P < 0.05. In kidney transplant recipients group, the levels of hemoglobin, total protein, urea nitrogen, creatinine before and after operation had no significant differences (P>0.05). After operation, the levels of hemoglobin, total protein, urea nitrogen, creatinine in two groups had no significant differences (P>0.05). In kidney transplant recipients group, the quality of life (QOL) score before operation was 5 scores in 4 cases and 6 scores in 1 case, and those after operation were zero in 3 cases and 1 score in 2 cases. Conclusions Under the sufficient preoperative preparation and assessment, the renal transplant recipients with BPH patients can improve the symptoms of urinary obstruction and obtain satisfactory clinical efficacy as common BPH patients.

OBJECTIVE:
To investigate the expression of miRNA-204 in patients with NPC and to analyze the as- sociation of the expression with the cIinicopathologicaI features and prognosis.
METHOD:
The expression levels of miRNA-204 in 50 patients with NPC and 40 patients with nasopharyngeal chronic inflammation were detected by using stem-loop real-time reverse transcription-polymerase chain reaction RT-PCR. Analysis of the relationship between microRNA and prognosis by Kaplan-Meier method.
RESULT:
Expression levels of miRNA-204 were down- regulated in patients with NPC as compared with patients with nasopharyngeal chronic inflammation (P < 0.05). The expression of miRNA-204 was associated with EBV infection, differentiation, lymphatic metastasis and TNM stages (P < 0.05). Low miRNA-204 expression was significantly correlated with shorter overall survival (P < 0.05) of NPC.
CONCLUSION
The downregulation of miRNA-204 expression has related with disease progression and miRNA-204 can serve as a potential therapeutic target for NPC.

Population pharmacokinetics of vancomycin (VAN) in the Chinese patients was described by using nonlinear mixed-effects modeling (NONMEM). 619 VAN serum concentrations data from 260 patients including 177 males and 83 females were collected separately from two centers. A one-compartment model was used to describe this sparse data. No significant difference was observed between two center datasets by introducing SID covariate. The final model was as CL= (θ (base0+ θ(max) x(1 -e(-θ(Age)(Age/72) and V = θ x θ (Age)(Age/72). The creatinine clearance (CL(Cr)) and Age were identified as the most significant covariate in the final model. Typical values of clearance (CL) and volume of distribution (V) in the final model were 2.91 L x h(-1) and 54.76 L, respectively. Internal model validation by Bootstrap and NPDE were performed to evaluate the robustness and prediction of the final model. The median and 95% confidence intervals for the final model parameters were based on 1000 Bootstraps. External model evaluation was conducted using an independent dataset that consisted of 34 patients to predict model performance. Pharmacodynamic assessment for VAN by AUC (0-24 h) to MIC ratios of over 400 was considered to be the best to predict treatment outcomes for patients. AUC (0-24 h) was calculated by clearance based on the above population model. The results indicate that the conventional dosing regimen probably being suboptimal concentrations in aged patients. The approach via population pharmacokinetic of VAN combined with the relationship of MIC, Age, CL(Cr) and AUC(0-24 h)/MIC can predict the rational dose for attaining efficacy.
