1.Effects of ACEI on the expression of ACE and ERK and the changes of atrial fibrosis in patients with atrial fibrillation
Journal of Chongqing Medical University 1986;0(02):-
Objective:To study the expression of angiotensin-converting enzyme(ACE),extracellular signal-regulated kinase(ERK),and the changes of atrial fibrosis in patients with rheumatic heart disease(RHD) and atrial fibrillation(AF) treated with angiotensin-converting enzyme inhibitor(ACEI).Methods:Atrial tissues were obtained from the right appendage during open surgery in 35 patients with RHD.The mRNA of ACE and ERK2 were semi-qualified by reverse transcription-ploymerase chain reaction(RT-PCR) and normalized to the glyceraldehyde 3-phosphate dehydrogenase(GAPDH).Western blotting analysis was employed to examine the expressions of ACE and phosphorylated ERK(pERK).Atrial collagen volume fraction(CVF) was detected by Masson's stain.Results:The mRNA of ACE and ERK2 or the protein of ACE and pERK were significantly increased,and CVF was significantly increased in patients with chronic atrial fibrillation(CAF) compared with sinus rhythm group(SR)( P 0.05).Conclusion:The expressions of ACE,ERK2 and pERK increase,and fibrosis is more severe in RHD patients with CAF as compared with those with SR.Compared with CAF patients treated without ACEI,the expressions of ERK2 and pERK significantly decrease( P 0.05)in CAF patients treated with ACEI.This suggests that the increasing expression of ERK2 and pERK resulting from local renal angiotensin-converting enzyme system activation mediates the development of atrial fibrosis,and ACEI may contribute to lesser atrial fibrosis in RHD patients with AF.

According to the sera aquaporin-4 antibody (AQP4), neuromyelitis optica (NMO) can be classified into two types as AQP4 antibody positive (AQP4+) and negative (AQP4-). However, the NMO patients with AQP4- are prone to delayed treatment, and may have a different pathogenesis compared to that in patients with AQP4+. Scientific researches and the clinical trials on NMO with AQP4- will deepen the understanding of NMO pathogenesis and help to make an early accurate diagnosis and rational therapy for NMO with AQP4-. This review aims to summarize the progress in clinic diagnosis for NMO patients with AQP4-.

Pulmonary hypertension (PH) is a progressive disorder characterized by abnormally elevated blood pressure of the pulmonary circulation. PH progresses rapidly to right ventricular (RV) failure and even death without treatment. Cardiac magnetic resonance (CMR) is an accurate and reproducible tool for the assessment of RV morphology and function, which plays an important role in the prognosis of patients with PH. The aim of this study is to review the clinical application and research progress of CMR in evaluation of PH.
4.Advances in methylenetetrahydrofolate reductase gene polymorphisms studies
Chinese Journal of Laboratory Medicine 2016;39(7):544-547
Methylenetetrahydrofolate reductase (MTHFR) is an enzyme that plays a critical role in the folate and homocysteine metabolism.MTHFR mutation leads to decreased 5-methylenetetrahydrofolate synthesis.Consequently, it influences the conversion of homocysteine to methionine causing homocysteine accumulation.Homocysteine has been considered as an independent risk factor for a variety of diseases such as cardiovascular diseases , neurological and psychiatric disorders as well as cancers .The study on the correlation between methylenetetrahydrofolate reductase gene polymorphisms and diseases and the discovery of its clinical value is getting more and more attention.

Tianjin Medical Journal 2016;44(5):629-631
Objective To study the clinical effects of recombinant human epidermal growth factor (rhEGF) gel combined with tacrolimus treatment on facial hormone-dependent dermatitis, and to investigate its influence in skin function and recurrence of dermatitis. Methods Forty-eight outpatients with facial hormone-dependent dermatitis were randomly divided into treatment group (n=24, treatment with tacrolimus combined rhEGF gel) and control group (n=24, treatment with tacrolimus). The moisture of skin, sebum content and transepidermal water loss (TEWL) were examined before treatment and 4 weeks after treatment in two groups. Eczema area and severity index (EASI) were calculated at 1 week, 2 weeks and 4 weeks after treatment. The adverse reactions and recurrence of dermatitis were observed during the treatment as well. Results Compared with pre-treatment, the moisture of skin and sebum content were increased (P<0.05) and the TEWL was decreased (P<0.05) after 4-week treatment. The differences were not statistically significant between two groups. The obvious effective rate of the treatment group (45.8%) was not significantly different from that of the control group (20.8%) after 1 week of treatment (P>0.05), but it is much higher in treatment group after two-week treatment (79.2%vs. 50.0%, P<0.05) and after four-week treatment (91.2% vs. 62.5%, P<0.05). Furthermore, there was no adverse reaction in the treatment group, and the recurrence rate was much lower in treatment group (12.5%) than that of the control group (37.5%,χ2=4.03,P<0.05). Conclusion Recombinant human epidermal growth factor gel has an auxiliary curative effect on facial hormone-dependent dermatitis and can significantly improve skin function, and the recurrence rate of dermatitis is low.
