Objective To find the effective therapeutic arrangement through investigating the clinical characteristics of chronic cardiac insufficiency with anaemia. Methods A total of 46 cases of anemia from 315patients who had been admitted to department of cardiology, the First Affiliated Hospital, Harbin Medical University for chronic cardiac insufficiency with anaemia were selected. They were divided into two groups. There were 22 patients in the first group who only accepted treatment to improve cardiac function (normal cardiac, diuretic,vasodilator therapy, etc.), and 24 patients in the second group who accepted treatment to improve cardiac function while receiving anti-anemia therapy treatment, oral ferrous sulfate tablets(0.3 g/tablet), 1 tablet each time, 3 times a day and(or) 2 times per week subcutaneous erythropoietin 3000 U. The hemoglobin(Hb), red blood cell(RBC) ,hematocrit (HCT), left ventricular ejection fraction (LVEF), fractional shortening (FS), stroke volume (SV) , cardiac output(CO) and E peak and A peak ratio(E/A) were observed before and after treatment. By logistic regression, grade grade Ⅱ , Ⅲ , Ⅳ, the incidence of anaemia were 7.9% (10/126), 19.2% (23/120) and 24.6% (17/69),respectively. Grade Ⅱ compared with grades Ⅲ, Ⅳ, the difference was statistically significant (x2 = 4.08, 3.12, all (3.49 ± 0.17) × 1012/L, (0.36 ± 0.08)%, (48.9 ± 3.11)%, (15.6 ± 1.8)%, (38.9 ± 3.7)%, (4.4 ± 1.6)% and (130.7 ±5.75)g/L, (4.12 ± 0.25) × 1012/L, (0.43 ± 0.02)%, (58.5 ± 2.65)%, (18.0 ± 2.5)%, (49.1 ± 7.7)%, (5.1 ± 1.2)%in the first and second groups, respectively. The difference between the two groups was statistically significant(t =value of Hb, RBC, HCT, LVEF, FS,SV, CO were (102.7 ± 6.93)g/L, (3.41 ± 0.12) × 1012/L, (0.35 ± 0.07)%,(47.5 ± 2.86)%, (16.0 ± 2.4)%, (38.2 ± 7.9)%, (3.7 ± 1.4)%, respectively. Compared with those after treatment,the difference was statistically significant (t = 15.632, 13.325, 5.569, 17.182, 3.186, 2.999, 3.074, all P ＜ 0.05);Ⅳ-level relative risk were 1.62, 3.14(P ＜ 0.05 or ＜ 0.01) .

This paper is to report the exploration of the activation of Rho/ROCK signal pathway in 5-HT-induced proliferation of rat pulmonary artery smooth muscle cells (PASMCs) and the inhibitory effect of m-Nis on this pathway. PASMCs were cultured with the explant technique. MTT assay was used to explore the proliferation of PASMCs after 5-HT treated for different time and the intervening effect of m-Nis. RT-PCR and Western blot were used respectively to explore the mRNA expression of RhoA, ROCK1 and the protein expression of p-MYPT1 in 5-HT-treated PASMCs and intervening effect of m-Nis. The results of MTT assay suggested that 5-HT (1 µmol · L(-1)) treatment for 12-72 h significantly induced the proliferation of rat PASMCs (P<0.05 or P < 0.01), which were inhibited by m-Nis (1 x 10(-5), 1 x 10(-6), l x 10(-7), 1 x10(-8) mol · L(-1)) in dose-dependent manners (P < 0.05 or P < 0.01). Similarly, the mRNA expression of RhoA, ROCK1 and the protein expression of p-MYPT1 were also inhibited by m-Nis in different degrees (P < 0.05 or P < 0.01). Thus, the results of this study suggested that Rho/ROCK pathway played an important role in 5-HT-induced proliferation of rat PASMCs, m-Nis inhibited 5-HT-induced proliferation obviously, which may be related to the blockage of Rho/ROCK signal pathway.
