China Pharmacist 2017;20(2):374-376
Objective:To investigate the change of insoluble particles in 4 traditional Chinese medicine injections at different con-centrations in 0. 9% NaCl injection. Methods:Fufang Kushen injection, Shuxuetong injection, Lugua Duotai injection and Honghua Huangsesu injection were diluted by 0. 9% sodium chloride injection to obtain low concentration and high concentration solutions. The insoluble particles number of initial injections and dilutions at different time points(0,2,4,and 5 h) was detected according to the in-soluble particles test described in the fourth principle 0903 of China Pharmacopoeia (2015 edition). Results:The number of insoluble particles in 4 traditional Chinese medicine injections and 0. 9% sodium chloride injection met the requirements. The insoluble particles (≥25 μm) in 4 traditional Chinese medicine injections at different concentrations were few and almost stable with time, the insoluble particles(≥10 μm) showed an increasing trend in a concentration-dependent manner and varied with time. Conclusion:The insoluble particles(≥10 μm) in traditional Chinese medicine injections at high concentration are more than those at low concentration, which suggests that the concentration of traditional Chinese medicine injections should be restricted strictly according to the prescriptions and used up as soon as possible.

4.Role of three different extracellular matrixes in the activation of rat microglia
Chinese Journal of Tissue Engineering Research 2007;0(16):-
AIM: Integrins act as receptors for molecules of the extracellular matrix (ECM) and play a major role in mediating cell morphology change,metabolism,function,migration,proliferation and differentiation. It is still unclear that whether ECM is associated with regulation of microglial activation and integrin expression. The study investigated the effects of three different ECM (fibronectin, vitronectin and laminin) on the expression of rat microglia integrin. METHODS:Experiments were performed in Research Center for Clinical Neurology, Tongji Medical College of Huazhong University of Science and Technology from May 2006 to August 2007. ①Neonatal Wistar rats were bought from Experimental Animal Center of Tongji Medical College. Animal intervention met the animal ethical standard. ②Rat microglia was cultured and purified. Culture plate was coated with fibronectin, vitronectin and laminin, and non-ECM served as control. ③The influence of individual ECM on microglia integrin expression and microglia surface expression of MHC Ⅰ by flow cytometry. RESULTS:①MHC classⅠexpression on rat microglia was significantly increased by fibronectin and vitronectin(P

6."Research Progress in Prevention and Treatment of Pediatric Diseases Based on TCM Theory of""Correspondence between Man and Nature""in Chronomedicine"
Chinese Journal of Information on Traditional Chinese Medicine 2017;24(8):121-124
Correspondence between man and nature theory is the core of TCM chronomedicine, and also plays an important role in ancient Chinese philosophy. The theory believes that distinguishing the rhythm is the foundation of treatment; complying with nature is the core of treatment; taking advantage of wane and wax is the method of treatment. This article combined the physiological and pathological characteristics of children to review the prevention and treatment of pediatric diseases based on chronomedicine, with a purpose to provide inspirations for clinical treatment.
7.Effects of melatonin on retinal oxidative stress in short-term diabetic retina
Chinese Journal of Experimental Ophthalmology 2011;29(3):215-219
Background Oxidative stress is one of the pathogenesis mechanisms of diabetic complications.Melatonin is the most powerful antioxidant in living organism.Seldom study on the effects of melatonin on diabetic complications is found in China now.Objective This study aimed to detect the expression and alteration of malonadehyde(MDA),glutathione(GSH)and glial fibrillary acidic protein(GFAP)in retina with experimental diabetes and explore the effects of melatonin on retinal oxidative stress in diabetic rats. Methods The animal models of diabetes were established by injection of 2% streptozocin via caudal vein(STZ,45 mS/kg)in 48 6-week-old clean SD rats.Isometric citric acid buffer solution wag injected in 24 normal.rats as control group.Seven days after injection of STZ,melatonin(10 mg/kg)was injected into the abdominal cavity of 24 diabetic rats in melatonin group dailv,and the equal volume of normal saline was injected in other 24 diabetic rats(model rats)and 24 rats in normal control group.The animals were sacrificed and retinas were obtained in three groups in 4,6 and 8 weeks respectively.Immunohistochemistry and Western blot were used to detect the expression of GFAP in rat retina.The levels of MDA and GSH in retina homogenate were assayed by spectrophotometer.This experiment complied the Regulations for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission.Results The expression of GSH in model group was lower than that in melatonin group or control group at 4,6 and 8 weeks (all P<0.05).However,no statistically significant difference was seen in the expression level of GSH between melatonin group and normal control group at 4 and 6 weeks(P>0.05),and in the eighth week,expression of GSH in melatonin group was lower than that in control group(P<0.05).The expressions of MDA and GFAP were more prominent in the model group than in melatonin group and control group in 4,6 and 8 weeks(P<0.05),but no significant difference was found between melatonin group and control group at 4 and 6 weeks(P>0.05).The expressions of MDA and GFAP in melatonin group were higher than those in control group at 8 weeks(P<0.05).Conclusion Melatonin plays a powerful effect in protecting the retina from oxidative stress in diabetes retina by downregulating the MDA level,upregulating GSH level and inhibiting GFAP expression.

The most effective treatment for acute ischemic stroke is intravenous thrombolysis and endovascular treatment. The proportion of patients with acute ischemic stroke receiving intravenous thrombolysis and endovascular treatment in China is low, and pre-hospital delay is an important reason. This article reviews the influencing factors and intervention measures of pre-hospital delay.
10.The role of NgR - Rhoa - Rock signal pathway in retinal ganglion cell apoptosis of early diabetic rats
International Eye Science 2014;(9):1570-1573
To study the function and mechanism of the NgR-Rhoa- Rock signal pathways which exists in the retinal ganglion cells apoptosis in diabetes mellitus (DM) rats.
● METHODS: Some healthy SD rats were operated by means of single intraperitoneal injection of 1%streptozotocin based on the standard of 50mg/ kg wight, after that the blood sugar value was greater than 16. 7mmol/ L as DM model, then randomly divided into 3 groups, each group was 10 rats. ln addition to take 10 healthy SD rats as control group. Four groups of rats were bilaterally eyeball intravitreal injection in turn with NgR-siRNA virus 10μ L (siRNA group), NgR-siRNA virus diluted 10μ L ( DM group), NgR - siRNA virus - negative -control solution 10μ L (siRNA blank group), NgR- siRNA virus diluted 10μ L ( normal control group ), and fed normally. During that time, some life indexes like blood glucose, body mass, etc. were measured and recorded. After 12wk, the expression of NgR and Rhoa, HE staining, and TUNNEL staining were detected by Western blot analysis.
● RESULTS: Western blot analysis: compared with normal control group, the expression of NgR and Rhoa in DM group and siRNA blank group increased significantly (P<0. 01), while siRNA group was no significant change (P > 0. 05); compared with DM group and siRNA blank group, the expression of those proteins significantly lowered in siRNA group. HE staining: compared with normal control group, some extent ganglion cells arranged disorder, irregular shape, spacing not consistent were all found in three groups of model rats;compared with DM group and siRNA blank group, there was some improvement in siRNA group of ganglion cells about the order and shape size. TUNEL staining:compared with normal control group, there were retinal ganglion cells apoptosis in all of three groups of model rats. Compared with DM group and siRNA blank group, the number of retinal ganglion cells apoptotic cells was less, and the shape of cells had improved significantly in siRNA group.
●CONCLUSlON: ln the DM phase, the expression of NgR and Rhoa were up - regulation, the condition of diabetic retinal ganglion cell apoptosis was improved after that the NgR-Rhoa-Rock signal pathways had been inhibited.
