Objective:To investigate the clinical application and adverse events of vinpocetine injection. Methods:The application of vinpocetine injection in the patients in neurology department during December 2013 and December 2014 in a hospital was statistically analyzed. The adverse reactions of the injection reported in the professional literatures and relevant documents were also retrieved and statistically analyzed. Results:The infusion concentration of vinpocetine injection for 363 patients was more than 0. 06 mg·ml -1 ,and 3 cases of adverse reactions appeared with the main symptoms of rash and drug fever. Among 28 published literatures,19 articles were with the infusion concentration of vinpocetine injection above 0. 06 mg·ml-1 and 8 articles reported adverse reactions in varying degrees. Conclusion:Clinicians should pay attention to the instructions in the clinical course of medication in order to improve the safe and rational use of drugs.

OBJECTIVE:To investigate the genetic polymorphisms of cytochrome P4503A4(CYP3A4) in epilepsy patients treated with carbamazepine,and to provide reference for individual drug regimen.METHOD:Blood samples were collected from epilepsy patients treated with carbamazepines.Mutations in CYP3A4 gene were detected by polymerase chain reaction and restriction fragment length polymorphism(PCR-RFLP).RESULTS:After screening the 141 subjects,the individual mutation rates of the allele CYP3A4*4 and CYP3A4*6 were 0.71%.No allele CYP3A4*5 was found in 141 subjects.CONCLUSION:CYP3A4 genetic polymorphisms may change the activity of CYP3A4 gene.

Objective:To investigate the polymorphism of the (MTHFR) C677T and its correlation with the severity of hypertension in Shanxi Province.Methods:A total of 306 patients with essential hypertension from the Second Hospital of Shanxi Medical University from January 2017 to January 2018 were selected as subjects. The clinical data of these patients were extracted from the hospital information system. The biochemistry index, including homocysteine (Hcy) were collected from the hospital laboratory test system and the polymorphism of MTHFR C677T gene was analyzed by polymerase chain reaction (PCR). Logistic regression analysis was used to estimate the severity of hypertension.Results:The frequencies of CC, CT and TT genotypes in patients with essential hypertension in Shanxi were 22.22%, 47.06% and 30.72. The C677T genotype and allele frequency revealed no signifcant departures from Hardy-Weinberg equilibrium in the population from the Shanxi region. Compared with MTHFR 677CC, MTHFR 677CT and MTHFR 677TT genotypes could increase the severity of hypertension by 2.29-fold and 2.24-fold. Smoking, family history of hypertension , Hcy and TG were independent risk factors for increasing the severity of essential hypertension ( OR=2.04, 1.81, 1.04, 1.26). Conclusions:MTHFR C677T genotype, smoking, family history of hypertension, Hcy and triglycerides could be important genetic and high-risk factors for development of severe hypertension , which will help to identify populations at high-risk of hypertension and may facilitate the development of hypertension control strategies.

It is recommended that cyclophosphamide combined with corticosteroids should be used as the first-line treatment of ANCA ( antineutrophil cytoplasmic antibody) associated with systemic vasculitis ( AASV) , however, cyclophosphamide has notable ad-verse reaction of causing pulmonary fibrosis ( PF) . In this paper, whether cyclophosphamide should be used in an AASF patient with PF was analyzed in order to decide whether AASV with PF is one of contraindications of cyclophosphamide in clinical practice.

Objective To characterize 16S rRNA methylase encoding genes associated with aminoglycoaides resistance, gene cassettes of class Ⅰ integrons of the multidrug-resistant Acinetobctcter spp. The sixty one Acinetobacter isolates were collected at the Second Hospital of Shanxi Medical Uni versity from July, 2007 to May, 2008. Methods Species identification was confirmed by sequence analysis of the blaOXA-51-like gene and 16S-23S rRNA gene space-region. Antimierobial susceptibility tests were performed by agar dilution method. 16S rRNA methylaae encoding genes and gene cassettes associated with integrons were amplified by PCR method. Results Among the sixty one strains, there were fifty five of Acinetobacter baumannii, three genospecies 3TU, one 13TU, one Aeinetobaeter ealcoacetieus, and one Aeinetobaeter haemolytieus. Forty eight isolates showed high-level resistance to three aminoglyeosides, including amikaein, tobramyein and gentamicin. The armA gene was found in 47 isolates and all isolates were negative for rmtA, rmtB, rmtC and rmtD genes. The Intl gene was found in 27 isolates. The gene cassettes contained arr-3, accA4,ctacCI ,catB8, aadA1 or dfrA12 genes. According to the PFGE DNA patterns, 5 distinct clones of armA-pasitive strains were identified. Clone A and Clone B were the dominant clones, widely distributed among different divisions. Condnsions 16S rRNA methylase encoding gene (armA) distributed widely in muhidrug-resistant Acinetobacter spp. The armA gene is not located in class Ⅰintegron. The class Ⅰ integron carries multiple resistant genes associated with aminoglycosides and chloramphenieol resistance.PFGE analysis suggests that armA-pesitive strains are widely spread in our hospitaL Effective infection control measure should be conducted in order to control the outbreak of resistant bacteria.
