Objective:To establish the alcoholic fatty liver(AFL) animal models,and to explore the protective effect of Zhi Zi Da Huang Tang (ZZDHT) on the rats with AFL and its dosage.Methods:A total of 54 SD rats were divided into normal control group (n=10) and model control group (n=44).The rats in model control group were given alcohol by lavage (50% ethanol solution 6.0 mL·kg-1) combined with high-fat feed to establish the rat models of AFL.After 4 weeks,the rats in model control group were randomly divided into model group(treated with water),simvastatin group (10 mg·kg-1),low and high doses (5.0 and 10.0 g·kg-1) of ZZDHT groups,and there were 10 rats in each group.Every 2 weeks during the process,the body weights and levels of serum total cholesterol (TC),triglyceride (TG),aspertate aminotransferase (AST),and alanine aminotransferase (ALT) were detected.After 4 weeks,the body weights and liver weights of the rats were detected;the levels of TC,TG,AST,ALT,alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) in serum and liver tissue of the rats of were detected;the levels of tumor necrosis factor-alpha (TNF-α),interleukin-6 (IL-6) and interleukin-1β(IL-1β) in serum of the rats were detected;the morphology of liver tissue was observed by HE staining and the pathological examination was performed.Results:Compared with normal control group,the levels of serum TC,AST,ALT,TG,TNF-α,IL-6,and IL-1β of the rats in model group 4 weeks after administration were significantly increased (P<0.05 or P<0.01).Compared with model group,the levels of serum TC,TG,AST,and ALT of the rats in low and high doses of ZZDHT groups 4 weeks after administration were decreased (P<0.05 or P<0.01);the levels of serum TNF-α and IL-6,IL-1β of the rats in high dose of ZZDHT group were decreased (P<0.01);the levels of serum TNF-α and IL-1β of the rats in low dose of ZZDHT group were decreased (P<0.01);the levels of serum ADH and ALDH in liver tissue of the rats in low and high doses of ZZDHT groups and simvastatin group were decreased(P<0.05 or P<0.01).The HE staining result showed that compared with model group,the pathological conditions of the liver tissue of the AFL rats in ZZDHT groups were significantly improved.Conclusion:ZZDHT can significantly improve the liver injury caused by high fat diet combined with alcohol and fat liver lesions.

Objective:To evaluate the hemostatic effects of our self-designed pelvic band with inflatable balloon in a swine model of hemodynamically unstable pelvic fracture.Methods:"Open-book like" fractures were created with the external iliac blood vessels exposed in 24 12-month-old female Bama miniature pigs which were randomly divided into 4 groups ( n=6). Group C (the control group) was subjected to no treatment other than exposure of the external iliac blood vessels, group D to no treatment following destruction of the external iliac blood vessels, group T1 to fixation with simple pelvic band after destruction of the external iliac blood vessels, and group T2 to fixation with our self-designed pelvic band with inflatable balloon after destruction of the external iliac blood vessels. The 4 groups were compared in terms of 40-min survival rate, bladder pressure, peak lactate value, total blood loss, bleeding rate, infusion rate, and angiographic images. Results:There was no significant difference in the baseline indexes among the 4 groups before experiment, showing comparability ( P>0.05). The 40-min survival rate in group T2 was 83.3% (5/6), significantly higher than that in groups D and T1 [0% (0/6) and 0% (0/6)] ( P<0.05). There were no significant differences among groups C, D, T1 and T2 in bladder pressure [(6.67±1.03) mmHg, (5.83±1.94) mmHg, (6.00±1.55) mmHg, and (6.00±1.10) mmHg] or in total blood loss among groups D, T1 and T2[(1,198.0±182.9) mL, (1,252.0±148.4) mL, and (1,150.0±125.7) mL] (all P>0.05). The peak lactate value in group T2 [(2.26±0.24) mmol/L] was significantly lower than that in group D [(5.00±0.60) mmol/L] and group T1 [(3.86±0.57) mmol/L], and the bleeding rate and infusion rate in group T2 [(25.83±5.49) mL/min and (26.00±4.69) mL/min] were also significantly lower than those in group D [(83.50±19.85) mL/min and (71.50±29.11) mL/min] and group T1 [(54.17±15.59) mL/min and (54.17±8.98) mL/min] (all P<0.05). Angiography showed contrast agent extravasation in group T2, especially from the artery, but the extravasation speed in group T2 was significantly slower than that in group D. Conclusion:In a swine model of hemodynamically unstable pelvic fracture, our self-designed pelvic band with inflatable balloon has a definite hemostatic effect on vascular injury which is better than that of a simple pelvic band.

ObjectiveTo evaluate the clinical effectiveness and safety of Bairui Granules （百蕊颗粒） in the treatment of acute pharyngitis with wind-heat syndrome. MethodsA multicenter， double-blind， double-simulation， randomised controlled trial was conducted， in which 162 patients with acute pharyngitis and wind-heat syndrome from 7 centers were recruited， and each center was divided into trial group and control group on the ratio of 2∶1. In the trial group， 108 cases were orally administered with Bairui Granules plus Reyanning Granules （热炎宁颗粒） simulant， and in the control group， 54 cases were orally administered with Reyanning Granules plus Bairui Granules simulant for 5 days， with a follow-up visit on the 6th day. Full analysis set （FAS） analysis and per protocol set （PPS） were used for analysis， respectively. The primary efficacy index was the disappearance rate of sore throat after 5-day treatment； the secondary efficacy indexes were the disappearance rate of sore throat after 3-day treatment， as well as the visual analogue score （VAS） of sore throat before treatment， every day during the treatment， and follow-up on day 6， and the traditional Chinese medicine （TCM） syndrome score was performed before treatment and at the follow-up on day 6. The effectiveness on TCM syndrome was evaluated at the follow-up on day 6， and the changes of vital signs， blood routine， urine routine， liver functions， kidney function， the adverse events before and after the treatment were recorded， and safety analysis set （SS） was analysed. Results162 patients entered the FAS and SS analyses， and 158 cases （105 cases in the trial group and 53 cases in the control group） entered the PPS analysis. FAS analysis showed that the disappearance rate of sore throat after 5-day treatment was 80.56% （87/108） in the trial group and 64.81% （35/54） in the control group， and the difference between groups was statistically significant （χ² = 5.10， P = 0.0239）. PPS analysis showed that the disappearance rate of sore throat after 5-day treatment was 80.00% （84/105） in the trial group and 64.15% （34/53） in the control group， and the difference between groups was statistically significant （χ² =4.85， P = 0.0277）. FAS and SS analyses both showed that the difference in disappearance rate of sore throat between groups on 3-day treatment was not statistically significant （P＞0.05）. Compared with those before treatment， the VAS scores of sore throat were lower in both groups during treatment on day 2， 3， 4， 5， and follow-up on day 6 （P＜0.01）， but the difference between groups at each time point was not statistically significant （P＞0.05）. TCM syndrome scores of both groups at the follow-up were lower than that before treatment， and those of the trial group were lower than those of the control group （P＜0.01）. The cure rate and effective rate of TCM syndrome of the trial group were significantly higher than those of the control group （P＜0.01）. There was no significant difference in blood routine， urine routine， liver function， kidney function between groups before and after treatment （P＞0.05）， and no serious adverse events occured in both groups. ConclusionBairui Granules showed clinical effectiveness in the treatment of acute pharyngitis of wind-heat syndrome， and it could significantly improve the clinical symptoms， accelerate the disappearance time of sore throat with good safety.
