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.

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.

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.

BACKGROUND: The repairing effect of distraction osteogenesis surgery in patients with craniofacial deformity secondary to cleft lip and palate remains unclear.OBJECTIVE: To evaluating the repairing effect of distraction osteogenesis surgery in patients with craniofacial deformity secondary to cleft lip and palate.METHODS: Databases of CNKI, Wanfang, VIP, CBM, Medline(ovid), science direct, ISI, as well as hand working were retrieved for the literatures about the curative effect of distraction osteogenesis on clef lip and palate patents with secondary craniofacial deformity which have been published. Clinical research about distraction osteogenesis used in clef lip and palate patents with secondary craniofacial deformity must have the same assignment style of investigation method and measurement indicators that include objective, design and detailed statistical method of the research. All of the findings can provide elementary data for weighted mean difference and 95% confidence interval (95%C/) or odd ratio and 95% C/. There are at least three patients included in the research and controlled by changes after operation. Meta-analysis was used to make a comprehensive quantitative analYSiS of ANB, the labial teeth overjet, SNA and nasolabial angle which are the soft or hard tissue measured by X-ray cephalometry for the forward-backward and perpendicular direction of the maxillafacial region. According to homogeneity tests, researches about ANB and overjet of the labial teeth adopted random effect model while SNA and nasolabial angle adopted fixed effect model. So total pooling weighted mean difference and its corresponding 95%CI for the models were calculated. RESULTS AND CONCLUSION: Totally 9 references and 123 patients were involved. Homogeneity test showed that, researches about ANB and overjet of the labial teeth are heterogeneous while SNA and nasolabial angle are homoeonomous. Conusarteriosus maps showed no publication bias was observed in all the literature that used in this article. Meta-analysis results showed that, the total pooled weighted mean difference of ANB, overjet of the labial teeth, SNA and nasolabial angle were below zero, all showed significant statistical difference. Meta-analysis can prove the .curative effect of extraoral support-type distraction on the craniofacial deformity secondary to cleft lip and palate. To some extent, this reseamh will provide guidance for choosing therapeutic regimen by the clinicians. After rigid external distraction by Le Fort Ⅰ ostetomy, most of the patients show great changes such as the increased SNA and ANB angle, the flatter of the upper lip curvature followed by the increased nosolabial angle, cured reverse overjet and returned normal occlusion relations.

The article presented the drugs supply management mode reform in place since 2009 in the one district of Shanghai.Authors analyzed and commented the implementation and outcomes,and studied the potentials of successful promotion nationwide.They hold that such a mode works to some extent in terms of reducing management costs of medical institutions,lowering drug purchase price,encouraging rational drug use of such institutions,and reforming the compensation manner for medical institutions.This mode,however,calls for an operating environment in need of not only funding support,but also new concepts and economic development strength of the society as a whole.This means that such a mode is only recommended in developed areas in China.
