Polymorphism of MTHFR C677T gene and the associations with the severity of essential hypertension in Shanxi population of China / 中国医师杂志

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.

Pharmaceutical Practice in One AASV Patient with Pulmonary Fibrosis Treated with Cyclophosphamide / 中国药师

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.

Effect and Clinical Significance of Radiotherapy on the Expression of Multidrug Resistance-associated Protein in Cervical Cancer / 中国药房

OBJECTIVE:To investigate the effect and clinical significance of radiotherapy on the expression of multidrug resistance-associated protein(MRP) in advanced cervical cancer.METHODS:The immunohistochemistry method was applied to detect the expression of lung resistance protein(LRRP),glutathione-S-transferases-?(GST-?),thymidylate synthetase(TS) and type Ⅱ topoisomerase(TopoⅡ) in 23 patients with advanced cervical cancer before radiotherapy and after receiving 30 Gy dose radiation.RESULTS:The positive expression rates of LRRP,GST-?,TS and TopoⅡ before radiotherapy were 47.8%,56.5%,30.4% and 60.9%,respectively.The positive expression rates of LRRP,GST-? and TS in patients after 30 Gy dose radiation were 69.6%,73.9% and 73.9%,respectively,which were signficantly higher as compared before radiotherapy(P
