BACKGROUND: Multiple applications of opium medicines can induce the accommodative changes of morphology and function in some intracerebral nerve positions. These accommodative changes are important neurobiological bases inducing drug-desire and re-addiction after detoxification. However, the actual molecular mechanism is unclear at present.OBJECTIVE: To investigate the impacts of the generation of heroin-dependence and detoxification on brain-derived neurotrophic factor (BDNF) in rat to provide a laboratorial gist for the participation of BDNS in heroin-dependence and detoxification.DESIGN: A randomized controlled study by employing experimental animals as subjectsSETTING: Mental health center of a medical university affiliated hospital MATERIALS: The study was conducted in the Laboratory of Pharmacology,Faculty of Pharmacology, Chongqing Medical University between March 2004and July 2004. Totally 30 inbreeding clean male SD rats with a bodymass between 200 g and 250 g were obtained from the Experimental Animal Center of the Third Military Medical University of Chinese PLA. Rats were randomly divided into blank control group(control group), heroin-dependent group (heroin group), and naloxone detoxification group(naloxone group) with 10rats each.METHODS: Morphine was subcutaneously injected into the rat with dose-increasing method to establish heroin-dependence rat model. Rats of naloxone group received subcutaneously injection of 2 mg/kg of naloxone to excite abstinent symptoms. The same dose of normal saline (NS) was injected in rats of control group. Model rats of each group were observed biologically and behaviorally. BDNF expression at different brain zone of rats in three different groups was tested with immunohistochemistry and digoxin-labeled oligonucleoide probe in situ hybridization technique.Comparison of the evaluation of abstinent symptoms in rats of each group.RESULTS: In the heroin group, the relative content of BDNF protein was higher in frontal lobe cortex, locus caeruleus and hippocampus than that of the control group( P ＜ 0.05); BDNFmRNA relative content was higher in frontal lobe cortex than that of the control group( P ＜ 0. 05) . In naloxone group, BDNF and its mRNA relative contents in frontal lobe cortex, locus caeruleus and hippocampus were higher than that of heroin group and control group ( P ＜ 0.05 ).CONCLUSION: Chronic administration of heroin could affect BDNF protein and its mRNA expressions in the corresponding brain areas of the rats, which suggests that the change of BDNF expression participates in heroin-dependence and detoxification.

Objective To investigate the causes of a suspected outbreak of lower respiratory tract infection (LR-TI)caused by carbapenem-resistant Acinetobacter baumannii (CRAB)in the general intensive care unit(ICU)of a hospital,and provide scientific evidence for effective control of healthcare-associated infection(HAI).Methods Epi-demiological investigation on patients infected with CRAB and on-site monitoring on ICU environmental hygiene from March 4 to 23,2014 were performed,active prevention and control measures were taken.Results A total of 7 patients developed CRAB infection,the total length of stay during epidemic period were 160 days,the infection density of LRTI was 43.75‰(7/160),4 of 5 patients at No.02 bed had CRAB LRTI.Univariate analysis revealed that adopting conventional sputum suction procedure was a risk factor;the qualified rate of bacterial count on the object surfaces was 31 .75% (20/63).CRAB was also isolated from outer frame of suction device of No.02 bed, which had the same antimicrobial pattern as CRAB from 7 patients’sputum.After taking a series of controlling measures,there was no CRAB infection case after March 24,2014,this outbreak was effectively controlled. Conclusion This suspected HAI outbreak may be caused by inadequate disinfection of outer frame of suction device contaminated by CRAB,and horizontally transmitted through manipulation of sputum suction by health care workers.Clean and disinfection of ICU environmental object surfaces is of great importance for preventing HAI.

Objective:To determine the expression of matrix metalloproteinase 13 (MMP13) in patients with psoriasis, and to evaluate the effect of tazarotene and narrow-band ultraviolet B (NB-UVB) on the expression of MMP13 in mice with psoriasis-like dermatitis.Methods:Lesional skin tissues and normal skin tissues were collected from 18 patients with psoriasis vulgaris and 10 healthy controls respectively, who were enrolled from General Hospital of Tianjin Medical University between May 2019 and August 2019, and serum samples were collected from all the subjects. A total of 25 specific pathogen-free (SPF) male BALB/c mice were randomly divided into control group, imiquimod group, imiquimod+NB-UVB group, imiquimod+tazarotene group and imiquimod+tazarotene+NB-UVB group. The control group received topical vaseline cream on the back once every morning; imiquimod group and imiquimod+NB-UVB group received imiquimod cream on the back once every morning; imiquimod+tazarotene group and imiquimod+tazarotene+NB-UVB group received imiquimod cream on the back once every morning, and tazarotene cream on the back once at night; imiquimod+NB-UVB group and imiquimod+tazarotene+NB-UVB group received NB-UVB irradiation on the back every other day at noon, with the dose being 300 mJ/cm 2 in the first session and increasing by 50 mJ/cm 2 in every session. The modeling lasted 7 days. After successful modeling, blood samples were obtained from the eyeballs of the mice, and skin tissues were resected from the back of the mice after being sacrificed by cervical dislocation on day 8. Changes in the epidermal thickness and pathological manifestations were observed by hematoxylin and eosin (HE) staining, protein expression of MMP13 in skin tissues was determined by immunohistochemical study, and the serum level of MMP13 was detected by enzyme-linked immunosorbent assay. Comparisons between 2 groups were performed by using two-independent-sample t test, comparisons among several groups by using one-way analysis of variance, multiple comparisons by using least significant difference- t test, and comparisons of enumeration data by using chi-square test. Results:The skin lesions of the patients with psoriasis were strongly positive for MMP13, and the MMP13 expression levels in the epidermis and serum (84.11±17.16, 13.29±3.95 μg/L, respectively) were significantly higher in the patients with psoriasis than in the healthy controls (11.98±4.08, 7.46±1.58 μg/L, respectively, both P< 0.01) . Compared with the control group (1.26±0.04 μm, 25.40±2.34, 185.76±7.22 μg/L, respectively) , a significant increase was observed in the epidermis thickness (7.93±0.59 μm, P< 0.01) , as well as MMP13 levels in the epidermis and serum in the imiquimod group (147.14±5.53, 215.98±15.17 μg/L, respectively, both P< 0.01) . Compared with the imiquimod group, the imiquimod+tazarotene group, imiquimod+NB-UVB group, and imiquimod+tazarotene+NB-UVB group all showed significantly decreased epidermal thickness (3.56±0.37 μm, 3.83±0.39 μm, 2.14±0.34 μm, respectively, all P< 0.05) , MMP13 levels in the epidermis (120.42±3.23, 91.08±0.46, 71.12±7.11, respectively, all P< 0.05) and serum (197.39±3.92 μg/L, 196.13±11.76 μg/L, 183.21±14.99 μg/L, respectively, all P< 0.05) . Conclusions:MMP13 protein expression markedly increased in the skin lesions and sera of patients with psoriasis, and decreased in skin lesions and sera of mice with psoriasis-like dermatitis after the treatment with tazarotene and NB-UVB. MMP13 may be involved in the development of psoriasis, and tazarotene and NB-UVB may inhibit the development of psoriasis by reducing the expression of MMP13.
