Chinese Pharmaceutical Journal 2012;47(24):2017-2022
OBJECTIVE: To study the genotype distribution of cytochrome CYP3A4, CYP2C9, CYP2C19, CYP2D6 in Han and Mongolian Chinese population and the allele and genotype frequency are compared between the Han and Mongolian. METHODS: CYP3A4, CYP2C9, CYP2C19, CYP2D6 of Han and Mongolian Chinese population were genotyped by PCR-RFLP. RESULTS: The allele frequencies of CYP3A4 * 5 in Han and Mongolian are 0, the allele frequencies of CYP3A4 * 18 in Han and Mongolian are 0.1838, 0.2025. The allele frequencies of CYP2C9 * 2 in Han and Mongolian are 0.0110, 0.0253; the allele frequencies of CYP2C9 * 13 in Han and Mongolian are 0, 0.003 2.The allele frequencies of CYP2C19 * 2 in Han and Mongolian are 0.386 0, 0.4146, the allele frequencies of CYP2C19 * 3 are 0.0515, 0.0443. The allele frequencies of CYP2D6 * 10 in Han and Mongolian are 0.5735, 0.4652. CONCLUSION: The study shows that there are no significant ethnic differences in the distribution of CYP3A4 * 18, CYP2C19 * 2, CYP2C19 * 3, CYP2D6 * 10 genotypes in Han and Mongolian. The CYP3A4 * 5 genotype is not found in this study and only one CYP2C9 * 1/* 13 genotype is found in Mongolian. For CYP2C9 * 2, the Mongolian is significantly lower than the Han, (P=0.023).

Objective To determine whether specific angiotensin-conventing enzyme inhibitor with ramipril would affect ventricular arrhythmia generation in rabbits after myocardial infarction and discuss the mechanism of its antiarrhymic efficacy.MethodsTwenty-four New Zealand rabbits (Wuhan Laboratory Animal Research Center) were separated into 3 groups:sham-operated (SHAM) group (n =8 ),myocardial infraction (MI) group ( n =8) and myocardial infraction with ramipril (RAM) group ( n =8).SHAM group received a median sternotomy without left ventricular coronary artery ligation.MI and RAM groups' rabbits received a median sternotomy followed by left coronary artery ligation. The successful anterior MI was confirmed by elevation of the ST segment with more than 0.2 mV in lead Ⅱ and Ⅲ.After MI,RAM group rabbits were fed with ramipril [ 1mg/ ( kg · d) ]by intragastric administration for 12 weeks.Before and after MI 12 weeks in three groups.Ventricular tachycardia or fibrillation episodes and the monophasic actionpotential duration in epicardium,mid-myocardium and endocardium cadiocytes were recorded.The statistical technique was t-test and ANOVA.Results Ventricular tachycardia or fibrillation episodes were markedly decreased in RAM group than that in MI group after 12 weeks [ (2.6 ± 0.8) vs.(12.4 ± 2.9),P <0.05 ].After MI 12 weeks,the action potential duration of repolarization 90% (APD90) of three-tier ventricular myocytes in MI group was prolonged than that before MI [ (258.2 ±21.1 ) vs.(230.1 ±23.2),( 278.0±23.8 ) vs.(245.8±25.4),(242.6±22.7) vs.(227.0±21.7),P<0.05]; however,it was not significant difference between before and after MI 12w in RAM group (P > 0.05 ).Moreover,the transmural dispersion of repolarization(TDR) was markedly increased after MI 12w in MI group than in SHAM and RAM group [ (36.2 ± 10.2 ) vs.( 18.7 ± 6.2 ),(24.9 ± 8.7 ),P < 0.05 ]; but the TDR was not significant difference between RAM and SHAM group ( 18.7 ± 6.2 ) vs.( 24.9 ± 8.7 ),P > 0.05].ConclusionsRamipril significantly reduced the malignant arrhythmia incidence in rabbits after MI.Mended the abnormal TDR was the mechanism for ramipril to therapy.

Objective:To investigate the correlation between preoperative blood platelet-to-lymphocyte ratio (PLR) and clinico-pathological features, as well as the effect of PLR on the prognosis of non-small cell lung cancer (NSCLC) patients after surgical resec-tion. Methods:Retrospective analysis was performed for 255 cases with histologically confirmed NSCLC that underwent curative re-section from January 2004 to December 2007. All patients were classified into two groups based on the median value of PLR. The rela-tionship between PLR and clinicopathological features was studied. Univariate and multivariate analyses were performed to assess the prognostic effect of preoperative PLR. Results:The median value of preoperative PLR was 130 (range:45.45 to 272.66). Based on the cut-off value of 130, all patients were divided into two groups:low PLR (≤130, n=127) and high PLR (>130, n=128). PLR was corre-lated with tumor site, T stage, and clinical stage. Five-year survival rates of low and high PLR patients were 49.6%and 33.6%, respec-tively, which indicated a statistically significant difference (χ2=12.577, P<0.001) between the two groups. Univariate analysis showed that smoking status, histological differentiation, clinical stage, T stage, N stage, postoperative adjuvant therapy and PLR were associat-ed with survival (P<0.05 for all). Multivariate analysis identified N stage, postoperative adjuvant therapy, and PLR as independent prog-nostic factors of all the patients. In addition, stratified analysis showed that the five-year survival rate of the low PLR group was higher than that of the high PLR group with or without lymph node metastasis, and the differences were statistically significant (P=0.020 and 0.037). Conclusion:An elevated blood preoperative PLR indicates poor prognosis in NSCLC patients. Preoperative PLR is an indepen-dent prognostic factor of NSCLC after curative resection.

OBJECTIVETo evaluate clinical outcomes of anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) reconstruction under arthroscopy and repair of the injured posteromedial complex structure of the knee joint in the treatment of posterolateral knee dislocation with multiple ligament injuries.
METHODSFrom March 2008 to August 2012,22 patients (16 males and 6 females, ranging in age from 20 to 53 years old, with an average of 30.5 years old) with posterolateral dislocation of the knee were treated with primary reconstruction of ACL and PCL, combined with the repair of injuries in the posteromedial complex and soft-tissue. Eight patients had injuries caused by sports,5 patients road accidents and 9 patients falling down. The ACL was reconstructed using the gracilis and semitendinosus tendons. The PCL was reconstructed using LARS artificial ligaments (14 cases), or gracilis and semitendinosus tendons (8 cases). Suture repair was performed in 17 patients with posteromedial ligament injuries,and self-semitendinosus strengthening operations were performed in 5 patients. Continuouspassive montion (CPM) and active exercises were executed after operation at early stage. The IKDC and Lysholm system were used to evaluate therapeutic effects.
RESULTSAll the patients were regularly followed up, and the duration ranged from 11 to 56 months (averaged, 39 months). According to the IKDC scale,9 patients got a grade A result, 10 got a grade B result, and 3 got a grade C result. The IKDC subject score was 89.6±3.1 and the Lysholm scores was 90.7±1.8 at the latest follow-up, which were both better than those before operation.
CONCLUSIONReconstructing the ACL and PCL and repairing injured posteromedial complex of the knee followed by an active rehabilitation is an effective method to treat posterolateral knee dislocation.
