To systematically review effectiveness and safety of Yinzhihuang Oral Liquid in the treatment of neonatal jaundice. A systematic retrieval was performed throughout China National Knowledge Infrastructure( CNKI),Wan Fang,VIP,Sino Med and PubMed,Medline,Cochrane Library databases from the establishment to April 2019. Randomized controlled trials of Yinzhihuang Oral Liquid in treatment of neonatal hyperbilirubinemia were retrieved. Clinical studies in line with the inclusion criteria were involved for data extraction,and the quality of the included literatures was evaluated by the risk bias assessment tool in the Cochrane review manual. Finally,Meta-analysis was performed by Rev Man 5.3 software. A total of 30 studies were involved,involving 3 923 child patients,including1 940 in observation group and 1 983 in control group. According to the results of Meta-analysis,the total effective rate( RR = 1. 22,95%CI[1. 18,1. 26],P<0. 000 01),level of TBi L after treatment( MD =-38. 78,95%CI[-48. 38,-29. 18],P<0. 000 01),time to jaundice resolution( MD =-1. 76,95% CI[-2. 10,-1. 41],P < 0. 000 01) and daily average decrease value of bilirubin( MD =11. 67,95%CI[8. 89,14. 45],P<0. 000 01) of observation group were significantly better than those of control group,with statistically significant differences. Adverse reactions were reported in nine studies,mainly including diarrhea,vomiting,fever,rash and other symptoms,which did not affect the treatment effect. The effectiveness of Yinzhihuang Oral Liquid combined with conventional therapy in treating neonatal jaundice was better than conventional therapy alone,with little adverse reactions. However,most of literatures included had a low research quality,which impacted the reliability of the conclusion. Therefore,it is suggested to conduct more largesample-size,multicenter,scientifically designed,strictly implemented high-quality randomized controlled trials in the future,in order to study the efficacy and safety of Yinzhihuang Oral Liquid in the treatment of neonatal jaundice.

OBJECTIVE: To analyze the changes of blood biochemical index and the pathological changes of myocardium and kidney in type 2 diabetic mouse at different time points, which can provide the basis for the selection of type 2 diabetic modeling time for later research. METHODS: After 6 weeks of feeding with high-fat diet, 24 healthy male ICR mice were injected with streptozocin (STZ, 30 mg/kg) intraperitoneally for 5 days to establish diabetic models. After 9 days, a random blood glucose ≥ 11.1 mmol / L was measured as diabetic mice. 4, 6 and 8 weeks after successfully preparing the diabetic mouse, 8 diabetic mice (a group)would be sacrificed each time. Then the biochemical and pathological conditions were analyzed: ① the indexes of heart and kidney were calculated. ②the serum levels of creatine kinase (CK), lactate dehydrogenase (LDH), creatinine (Cr) and blood urine nitrogen (BUN) were determined. ③ Histopathological changes of myocardium and renal tissues were observed by hematoxylin and eosin (HE) staining. Masson staining was used to observe the fibrosis of myocardium. PAS staining was adopted to observe the pathological changes of renal tissue. In addition, 8 ICR male mice were taken as the control group. RESULTS: At the 4, 6 and 8 week, cardiac organ coefficient, the values of LDH and CK were all increased compared with the control group. Cardiomyocyte hypertrophy and myocardial fibrosis could be observed. Renal organ coefficient, the values of Cr and BUN were increased. Glomerular hypertrophy, basement membrane thickening and atrophy could be perceived. CONCLUSION At the 6 week, related biochemical and pathological changes in diabetic mice were comparatively obvious and breeding time was relatively short. Thus, 6 weeks after the preparation of the diabetic mice would be the optimal time for type 2 diabetes mellitus modeling, proper for inventions of drugs and other research purposes including pathology, physiology, biochemistry, etc.

Aim To use microdialysis technology combined with ultra-high performance liquid chromatography tandem quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS) technology to study the effect of Achyranthes bidentata saponins (ABS) on rheumatoid arthritis (RA) and its mechanisms. Methods SD rats were randomly divided into adjuvant arthritis (AA) model group, blank control group and ABS administration group. AA rat model was induced by Freund's complete adjuvant. UPLC-Q-TOF/MS was used to collect joint cavity microdialysis fluid sample information of each group of rats. Results On 6th day after administration of ABS, an inhibitory effect on the paw swelling, improved the arthritis score (P < 0. 05), and better the pathological morphology of the synovial tissues were found in AA rats. Nineteen potential biomarkers were discovered and identified. Pathway enrichment analysis revealed that they mainly involved purine metabolism, pyrimidine metabolism, fatty acid biosynthesis and steroid hormone biosynthesis pathway. Conclusions Microdialysis combined with metabolomics can reveal the metabolic mechanism of ABS intervention on RA, laying a foundation for further study of the mechanism of ABS.
