Objective To investigate the clinical therapeutic effect of Chaishi fever particles on patients with epidemic encephalitis B and to study the machanism of anti-inflammatory.Methods One hundred and twenty one patients with epidemic encephalitis B admitted to the Second Clinical Medical College of Henan University of Chinese Medicine from January 2014 to May 2017 were enrolled, and they were divided into a routine treatment group (60 cases) and a traditional Chinese medicine (TCM) treatment group (61 cases) by random number table. The patients in routine treatment group were given symptomatic support and comprehensive treatment for 15 days, while those in the TCM treatment group were given as that of routine group with the addition of Chaishi fever particles 8 g, 4 times every day, orally taken for consecutive 15 days. The levels of tumor necrosis factor-α (TNF-α), interleukin (IL-1β, IL-10) in the serum of two groups were determined by enzyme-linked immunosorbent assay (ELISA), and the clinical therapeutic effect, complications and sequelae in two groups after treatment were observed.Results Compared with the routine treatment group, after treatment the time of body temperature recovering normal (days: 5.8±1.2 vs. 7.5±1.7), the coma time (days: 5.5±1.3 vs. 6.8±1.6), the remission time of convulsion (days: 5.2±1.4 vs. 6.5±1.5), and the length of stay in hospital (days: 22.6±1.9 vs. 25.2±1.8 ) were significantly shorter in TCM treatment group (P < 0.05). After treatment, the levels of serum tumor TNF-α and IL-1β were decreased, IL-10 was increased in both groups, moreover, compared with the routine treatment group, the changes were more obvious in TCM treatment group [TNF-α (μg/L): 11.4±3.6 vs. 14.6±3.5, IL-1β (μg/L): 22.3±6.2 vs. 26.2±5.6, IL-10 (μg/L): 225.2±19.2 vs. 186.2±21.5, allP < 0.05]. In addition, compared with the routine treatment group, the total effective rate was higher [98.3% (60/61) vs. 90.0% (54/60),P < 0.05], and the incidence of sequelae was lower [1.64% (1/61) vs. 13.3% (8/60),P < 0.05] in TCM treatment group.Conclusion The Chaishi fever particles can effectively treat the patients with epidemic encephalitis B and the action is related to the inhibition of inflammatory reaction.

OBJECTIVETo evaluate the clinical effectiveness of Yiqi Huoxue Tongyang Xiezhuo Recipe (YHTXR, capable of supplementing qi, activating blood, warming yang, and discharge turbidity) in treating coronary atherosclerotic heart disease (CAHD). and chronic heart failure (CHF) with carotid plaque patients, and to explore new ways of Chinese medicine (CM).
METHODSTotally 69 CAHD-CHF patients of qi deficiency phlegm stasis syndrome (QDPSS) with carotid plaque were recruited in this study using parallel cohort method. They were assigned to the treatment group (35 cases) and the control group (34 cases). Patients in the control group received routine treatment of Western medicine, while those in the treatment group were additionally treated with YHTXR (twice daily). The therapeutic course for all was three months. Cardiac function levels, echocardiography, carotid plaque, blood lipids and safety indicators were observed before and after treatment.
RESULTSAfter treatment the improvement of cardiac function levels was better in the treatment group than in the control group (P < 0.05). Decreased LDL-C levels were higher in the treatment group than in the control group (P < 0.01). There was statistical difference in left ventricular ejection fraction (LVEF), carotid intima-media thickness (IMT), LDL-C, TC, TG in the treatment group between before and after treatment (P < 0.05). LDL-C and TG also decreased in the control group after treatment (P <0.05). There was no significant difference in the left ventricular ejection fraction, carotid IMT, or TC in the control group between before and after treatment (P > 0.05). There was no significant difference in stroke volume, left ventricular end-diastolic diameter, the area of carotid artery plaque, or HDL-C in the two groups between before and after treatment (P > 0.05).
CONCLUSIONSYHTXR could effectively improve cardiac functions of CAHD-CHF patients of QDPSS with carotid plaque, reduce blood lipids and IMT. It had no significant adverse reactions for elderly patients in short term.
