Objective:To investigate the efficacy of modified Zhigancao decoction on Qi/ Yin-deficiency acute viral myocarditis and its effect on serum level of high mobility group box chromosomal protein 1 (HMGB-1). Methods:Eighty-eight patients with Qi/ Yin-deficiency acute viral myocarditis who received treatment in Chun'an Hospital of Traditional Chinese Medicine from July 2017 to December 2018 were included in this study. They were randomly assigned to undergo either standard conventional intervention (control group, n = 43) or treatment with modified Zhigancao decoction based on standard conventional intervention (observation group, n = 45) for 4 weeks. After treatment, serum levels of cardiac troponin I (cTnI) and HMGB1, traditional Chinese medicine symptom score, and clinical efficacy were compared between the two groups. Results:After 2 and 4 weeks of treatment, serum level of cTnI in the observation group was (590.22 ± 78.42) ng/L and (461.36 ± 52.44) ng/L, respectively, which was concurrently significantly lower than that in the control group, respectively [(621.41 ± 86.12) ng/L, (587.62 ± 67.94) ng/L, ( t2 weeks = 1.574, t4 weeks = 9.785, both P < 0.05). After treatment, traditional Chinese medicine symptom score in the observation group was significantly lower than that in the control group ( tfever = 27.650, tsore throat = 27.210, tpalpitation = 14.560, tvexation and chest tightness = 15.370, all P < 0.01). Total effective rate in the observation group was significantly higher than that in the control group [93.33% (42/45) vs. 72.09% (32/43), χ2 = 8.41, P < 0.05). After 2 and 4 weeks of treatment, serum level of HMGB1 in the observation group was concurrently significantly lower than that in the control group ( t2 weeks = 9.144, t4 weeks = 11.534, both P < 0.01). Conclusion:Modified Zhigancao decoction combined with conventional western medicine intervention for the treatment of Qi/ Yin-deficiency acute viral myocarditis exhibits great therapeutic effects possibly through downregulating serum level of HMGB1.

Objective To analyze the status of Huangshui River water pllution by chromium(Cr6+)and define the pollution source. Methods Water samples were collected from 5 monitoring points closely located at the bank of Huangshui River from the upper reaches to the lower reaches including A spring,Huanghai canal,Duoba water source well,Zhamalong,Xigangqiao,and also from the location of the upper reaches of Halejian River in the area of source of Huangshui River established as the control monitoring point during 1996-2003. The contents of Cr6+ in the water samples from above sampling points were determined. Results During 1999-2003,the average content of Cr6+ in the water samples from A spring was 45.192 mg/L,and those from Huanghai canal in the upper reaches of Huangshui River Zhamalong and Xigangqiao increased year by year gradually.By the end of 2003,Cr6+ hadn't been found in the water samples from the upper reaches of Halejian River,but Cr6+ had been found first in the water samples from Duoba water source well with a concentration of 0.007 mg/L. Conclusion Haibei Chemical Industrial Works near A spring was the main source for the Cr6+-pollution of water body of the upper reaches of Huangshui River.

Objective To investigate the diagnostic value of antibody to group A streptococcal polysaccharide (ASP) in diagnosing atypical rheumatic fever (RF). Methods Fifty-seven cases including 33 atypical RF and 24 recurrent attack of RF with chronic rheumatic heart disease were included, and 57 patients suffered from other diseases were used as control. Nitrous acid extraction and molecular sieve chromatography was adopted to extract and purify the polysaccharide. The isolated portion of polysaccharide which possessed strongest antigenity was used to detect the level of serum ASP by enzyme-linked immunosorbent assay (ELISA). Erythrocyte sedimentation rate (ESR), antistreptolysin-O (ASO) and anti-deoxyribonuclease B (anti-DNase B) were tested with the same samples. Results The sensitivity and specificity of ASP in the diagnosis of atypical RF was 73.7% and 76.6%; while 47.4% and 46.4% for ESR respectively. As for the evaluation of streptococcal infection, the sensitivity and specificity of ASP, ASO and anti-Dnase B were 73.7%, 15.6%, 65.4% and 76.6%, 94.6%, 44.6%, respectively. ROC curve analysis and discriminant analysis were adopted to compare these laboratory measurements. The results demonstrated that ASP was superior to other methods. Conclusion ASP has a higher sensitivity together with a higher specificity than the other three methods for diagnosing the activity of RF and the infection of streptoccus. It should be a promising diagnostic test for atypical RF.

Objective To investigate the effect of isovolumic hemodilution with 6% hydroxyethyl starch (HES) (200/0.5) on expression of intercellular adhesion molecule-1 (ICAM-1) after global cerebral ischemia-reperfusion in rats. Methods Eighty-four male Wistar rats weighing 230-280g were randomly divided into 3 groups: group Ⅱ sham operation (S , n = 20); group ischemia-reperfusion (Ⅱ , n = 32) and groupⅢ hemodilution with 6% HES (200/0.05) (H, n =32) . Group Ⅱ and group Ⅲ were further divided into 4 equal subgroups with 8 animals in each subgroup: 2h, 4h, 8h and 12h after beginning of reperfusion. Global cerebral ischemia was produced by permanent occlusion of bilateral vertebral arteries and cross-clamping of bilateral common carotid arteries for 10min and then clamping was released for reperfusion. In group Ⅲ acute normal volumic hemodilution was performed at 10 min after reperfusion was begun. 1ml/100g of blood was removed from artery and equal volume of 6% HES(200/0.5) was infused into the vein simultaneously. Hct was checked before and after hemodilution. The animals were decapitated at designed time and brain tissue was removed from ischemic area and frozen in liquid nitrogen. ICAM-1 expression was determined by using immunohistochemical technique. Results ICAM-1 expression significantly increased after 2h, 4h, 8h and 12h reperfusion in group Ⅱ and Ⅲ as compared with in group Ⅰ (P

Objective To investigate the effects of angiotensinⅡ (AngⅡ) on the Apelin mRNA and APJ mRNA expression in pulmonary microvascular endothelial ceils (PMVECs) in rats. Methods Pulmonary microvascular endothelial ceils obtained from 24 h old neonatal SD rats were cultured in DMEM liquid culture medium. The 2nd-4th generation PMVECs were inoculated on 6-well plates (5×105). The experiment was performed in two parts. In part Ⅰ different concentration of AngⅡ 0, 10-9, 10-8, 10-7, 10-6mol/L (group Ⅰ- Ⅴ) were added into the PMVECs. The expression of Apelin mRNA and APJ mRNA was determined at 24 h after addition of Ang Ⅱ by RT-PCR. In part Ⅱ the cells were exposed to 10-7 mol/L Ang Ⅱ. The expression of Apelin mRNA and APJ mRNA was determined immediately and at 1, 6, 12, 24, 48 h(group Ⅰ-Ⅵ) after addition of Ang Ⅱ by RT-PCR. Results In part Ⅰ Apelin mRNA expression was significantly higher in group Ⅱ (Ang Ⅱ 10-9 mol/L) but lower in group Ⅲ-Ⅴ (AngⅡ 10-8, 10-7, 10-6 mol/L) than in group Ⅰ (control, Ang Ⅱ 0 mol/L). The APJ mRNA expression was significantly lowered in group Ⅱ-Ⅴ in a dose-dependent manner as compared with control group (group Ⅰ). In partⅡ beth Apelin mRNA and APJ mRNA expression exhibited a bi-phasic response to AngⅡ 10-7 mol/L, increased at first and was then decreasing with time. The Apelin mRNA and APJ mRNA expression reached the peak at 1 h of incubation with Ang Ⅱ respectively. Conclusion Ang Ⅱ decreases both Apelin mRNA and APJ mRNA expression in PMVECs in a dose and time dependent manner. The down-regulation of Apelin mRNA and APJ mRNA expression may be involved in the mechanism of injury to PMVECs.
