RESUMO
OBJECTIVE： To study the relationships of polymorphism of MTRR gene rs1801394 locus and SLCO1B1 gene rs11045879 locus with drug concentration of methotrexate （MTX） and high-dose MTX （HD-MTX）-induced ADR in acute lymphoblastic leukemia （ALL） children. METHODS： From Oct. 2015 to Sept. 2018， 70 ALL hospitalized children of Han nationality in Sichuan area who received HD-MTX treatment and were in consolidation chemotherapy were selected retrospectively from Sichuan People’s Hospital. The blood concentration of MTX at 48 and 72 hours after administration was measured by EMIT. The genetic typing of MTRR gene rs1801394 locus and SLCO1B1 gene rs11045879 locus were detected with real-time PCR. The relationships of the polymorphism of MTRR gene and SLCO1B1 gene with MTX blood concentration [dose-corrected concentration （c48 h/D，48 h）， the proportion of children with different concentration of MTX （≤0.1， ＞0.1 μmol/L）] and ADR （such as myelosuppression， liver function damage， gastrointestinal response， mucosal damage， rash， etc.） were analyzed. Binary Logistic regression analysis for the correlation of ADR with different influencing factors （gene polymor- phism， blood concentration of MTX， immunophenotyping， body mass index， etc.） was carried out by Wald method. RESULTS： Totally 31， 32， 7 children with MTRR gene AA， AG and GG genotype， while 23， 37， 10 children with SLCO1B1 gene TT， TC and CC genotype were detected. The distribution of each genotype in 70 children conformed to Hardy-Weinberg equilibrium （P＞0.05）. There was no significant difference in c48 h/D（48 h） of children and the proportion of children with different concentration of MTX （72 h） among difterent genotypes of MTRR and SLCO1B1 gene （P＞0.05）. There was statistical significance in the incidence of liver function injury in children with different genotypes of MTRR gene （P＜0.05）， and the AA genotype was significantly higher than the AG+GG genotype （P＜0.05）. There was no correlation of MTRR gene polymorphism with the incidence of other ADR， neither SLCO1B1 gene polymorphism with the incidence of ADR （P＞0.05）. The results of Binary Logistic regression analysis showed that liver function damage in ALL children was related to the gene polymorphism of MTRR； gastrointestinal reaction was related to whether the plasma concentration was more than 0.1 μmol/L at 72 h； mucosal damage was related to the immune type and BMI of children； the occurrence of skin allergy was correlated with body weight of children（P＜0.05）. CONCLUSIONS： Gene polymorphism of MTRR rs1801394 locus may associated with the occurrence of HD-HTX-induced liver function injury in ALL children， but its polymorphism and gene polymorphism of SLCO1B1 rs11045879 locus are not related to MTX blood concentration in ALL children.
RESUMO
Objective: To explore the characteristics of adverse drug reactions (ADRs) in a grade three class A hospital to provide reference for rational drug use and reduction of ADRs. Methods: The new and serious ADRs reported during 2014 and 2016 were sta-tistically analyzed in terms of the report type, age, gender, administration route, drug variety and involving system. Results: The new and serious ADR reports reached to 400 cases, which accounted for 64. 52% of the total reports. Of the 400 ADR reports,there were 34. 25% distributed in the 60-74-year old. The proportion of male and female in the ADRs was basically equal, while that of male (50. 25% ) was slightly higher than that of female (49. 75% ). There were 57. 00% of ADRs caused by intravenous administration, and 31. 25% caused by anti-infective drugs, in which cephalosporins accounted for the most (32. 00% ). The most common manifesta-tion of ADR was damage to skin and its appendages, which accounted for 33. 00% , followed by the damage to gastrointestinal system (15. 50% ) and hepatorenal function (14. 00% ). Conclusion: Great attention should be paid to monitoring and reporting ADRs in our hospital, and drugs should be rationally used so as to reduce the occurrence of ADRs.
RESUMO
OBJECTIVE:To systematically evaluate the efficacy and safety of metronidazole combined with hydrogen peroxide for uterine cavity lavage in the treatment of puerperal infection. METHODS:Retrieved from PubMed,Cochrane library,Wanfang database,VIP,CBM and CNKI,Meta-analysis was performed by using Cochrane collaboration Rev Man 5.3 software after data extraction and quality evaluation with modified Jadad scale. RESULTS:A total of 16 RCTs were included,involving 1 280 patients. Meta-analysis showed that total response rate of observation group was significantly higher than that of control group [OR＝5.76,95%CI(3.21,10.35),P＜0.001],but febrile duration [MD＝－2.08,95%CI(－2.32,－1.84),P＜0.001],duration of clinical symptom [MD＝－2.71,95%CI(－2.89,－2.53),P＜0.001] and average hospital stay [MD＝－3.05,95%CI(－3.32,－2.79),P＜0.001] are significantly shorter than control group; the incidence of ADR [OR＝0.27,95%CI(0.08,0.89),P＝0.03] was significantly lower than control group,with statistical significance. CONCLUSIONS:Metronidazole combined with hydrogen peroxide for uterine cavity lavage show good therapeutic efficacy and safety in the treatment of puerperal infection.
RESUMO
Objective:To investigate the relationship of CYP2C19 gene polymorphisms and clopidogrel resistance in the patients with coronary atherosclerotic heart disease ( CAHD) accepted percutaneous coronary intervention ( PCI) in Chinese Han population from north Sichuan. Methods:The patients with CAHD undergoing PCI were recruited. The fluorescence in situ hybridization ( FISH) technology was used to detect the CYP2C19 gene polymorphisms in all the patients. According to the different genotypes, the patients were divided into different groups. The platelet maximum aggregation rate ( MAP) induced by ADP was detected before and after the administration of clopidogrel. Results:The 110 patients were divided into three groups:52(47. 3%) patients were divided into the fast metabolism group, 42(38. 1%) patients were in the moderate metabolism group and 16(14. 6%) patients were in the slow metab-olism group. Before the administration, there was no significant difference in the basic values of the platelet aggregation rate among the groups with various metabolism type (P=0. 873). In 24 hours after the administration of 300mg clopidogrel, there was notable differ-ence in the platelet aggregation rate (17. 74% ± 5. 87% vs 21. 44% ± 8. 71% vs 27. 05% ± 8. 83%, P=0. 044) and the decrease de-gree (20. 08% ± 5. 94% vs 18. 87% ± 4. 72% vs 11. 54% ± 2. 94%, P=0. 01) among the three groups. The moderate metabolism group and slow metabolism group had higher MAP with lower decrease degree than the fast metabolism group. Totally 21 patients (19. 1%)were with CR, and among them, 2 patients (3. 8%) were in the fast metabolism group,12 patients (28. 6%) in the moder-ate metabolism group and 7 ones (43. 8%) in the slow metabolism group, and the difference of CR distribution among the three groups was significant (P<0. 001). The moderate metabolism group and slow metabolism group were more likely to have clopidogrel resist-ance, especially the slow metabolism group. Conclusion: There is a certain relationship of CYP2C19 gene polymorphisms and clopi-dogrel resistance in the patients with CAHD accepted PCI in Chinese Han population from north Sichuan, and those with slow metabo-lism genotype are more likely to have clopidogrel resistance with reduced efficacy.
