OBJECTIVE:To investigate the characteristics and regulations of antibacterials-induced adverse drug reactions (ADR) in our hospital,and to provide reference for promoting rational drug use. METHODS:233 patients with antibacterials-in-duced ADR in our hospital from Oct. 2013 to Jun. 2015 were selected and analyzed statistically according to patient's age and gen-der,route of administration,the type of antibacterials,occurrence time,organs/systems involved in ADR,etc. RESULTS:There were a large number of ADR in patients age ≤18 and ≥70 years,accounting for 19.3% and 18.5%;the male was more than the female;the incidence of ADR induced by intravenous route was the highest,accounting for 94.0%. Most of ADR was caused by cephalosporins,accounting for 33.9%;ADR often occurred within 1 d after medication,accounting for 63.9%;lesion of skin and its appendants injury was main ADR,accounting for 39.3%. CONCLUSIONS:Adhere to theclear indications,a detailed inqui-ry about allergy history before drug use,right dose,suitable route of administration and course,and timely ADR disposal can re-duce the damage caused by ADR.

Objective To investigate the cause of excessive collagen accumulation in keloid tissue. Methods The ultrastructure of keloid was observed by transmission electron microscope. New formed collagen in keloid was localized with ABC immunohistochemical staining. Type I procollagen mRNA level in keloid tissue was determined by dot blot hybridization using human pro-al (I)collagenspecific cDNA probe. Results Numerous fibroblasts with abundant, well developed rough endoplasmic reticulum were exhibited in the ultrastructure of keloid. The type I procollagen mRNA levels were significantly increased in kreloid tissue. Immunohistochemical staining showed increased expression of new formed, type I procollagen in keloid tissue. Conclusion the fibroblasts are activated in collagen synthesis in active keloid. The enhanced collagen synthesis by fibroblasts is a critical factor leading to the overabundant collagen accumulation in keloid.

In this paper, an analysis was made on the varieties and standards of labiatae medicinal plants used in Tibetan medicine. The results showed 71 species of labiatae plants in 21 genera (including varieties) recorded in relevant literatures, involving 44 varieties of medicinal materials. Specifically, seven species (9.9%) were intersected with traditional Chinese medicines (TCM), 19 varieties (43%) were recorded in Chinese medicinal material standards at all levels, and 27 species (38%) were source plants. In Tibetan medicine standards and literatures, there are great differences between Tibetan names and translated Chinese names and among varieties of source plants. Apart from a few of varieties intersected with traditional Chinese medicines had complete standards and regulations in Chinese Pharmacopoeia, most of species only had characters, microscopic, physical and chemical identifications in Standards Issued by Ministry of Health-Tibetan Medicine, Tibetan Medicine Standard and local standards. Therefore, the Tibetan medicinal material variety-source specification and quality standard system shall be promoted on the basis of literatures research, investigations for resources and current applications and modern pharmaceutical studies.

Objective To observe changes of cognitive function and the expression of tumor necrosis factor alpha(TNF-α),interleukin 10(IL-10) in hippocampus of diabetic rats,and assess the role of inflammation in the possible pathogenesis of diabetic encephalopathy (DE).Methods 30 male SD rats were randomly divided into control group and diabetes mellitus group.After 4 weeks of feeding high fat diet,diabetes mellitus group according to 30mg/kg injected with streptozotocin to establish type 2 diabetic rat model.At the end of the experiment,cognition were evaluated using water maze test.The concentration of beta-amyloid(Aβ) in hippocampus of diabetic rats were detected through enzyme linked immunosorbent assay,and the expression of TNF-α,IL-10 were detected by Western blotting.The expression of Aβ,TNF-α,IL-10 were observed through immunohistochemistry.Results Time spent in the target quadrant in diabetes mellitus group was shorter than that in control group ((38.21± 3.68)s vs (42.10±2.62)s,t=3.105,P＜0.01).The frequency of crossing original platform site was less than that in control group((2.62±0.77) vs(3.69±0.95),t=3.184,P＜0.01).Compared with control group the expression of Aβ,TNF-α were higher(BothP＜0.01),and IL-10 were lower(P＜0.01)in diabetes mellitus group.The positive expression of Aβ,TNF-α were obviously and IL-10 were less obviously observed in diabetes mellitus group according to immunohistochemistry.Conclusion The cognitive decline in diabetic rats is possibly related to inflammatory cytokines expressing out of balance.

Objective To carry out the current status of internal quality control by statistical analysis of the Internal Quality Control (IQC)data of homocysteine in 2014 March.Methods Web-based External Quality Assessment (EQA)system was used to collect IQC data of homocysteine from 292 EQA participant laboratories nationwide.The data include thecoefficient of variation (CV)of IQC data under control in March 2014 and long-term cumulative data.Acceptable rates of CVs of two-lot internal quality controls in homocysteine were calculated according to 5 criteria,that were 1/3TEa,1/4TEa and the speci-fications based on biological variation including the minimal,appropriate and optimal allowable imprecision.The instrument the participant laboratories used were sorted into 6 groups and the passing rate of each group were calculated by the 5 crite-ria.Results 292 laboratories reported the data of level 1 IQC for homocysteine,106 of which reported the data of level 2 IQC.The passing rate was different according to different criteria.The passing rate had few difference by the criteria of 1/3TEa and the minimal allowable imprecision based on biological variation,which were from 63.36% to 76.42%.It was also true for 1/4TEa and the appropriate allowable imprecision based on biological variation,which were from 34.25% to 57.55. The passing rate was only 10.62%~16.98% by the criteria of appropriate allowable imprecision based on biological varia-tion.Statistical results showed that instruments the participant mainly used were HITACHI (77/292),Olympus (61/292), Roche (19/292),Beckman (14/292),Abbott (10/292)and Simens (10/292).The passing rates of all the instrument group had few difference except Simens group.Conclusion Most of the laboratories could meet the criteria of 1/3TEa and the min-imal allowable imprecision based on biological variation.But less than half of the laboratories could meet the criteria of 1/4TEa and the appropriate and optimal allowable imprecision based on biological variation.The precision performance of ho-mocysteine among laboratories needs further improvement.
