OBJECTIVE:To understand the public cognitive status about the adverse drug reaction(ADR),and provide refer-ence for improving the ADR reporting system. METHODS:Field to fill out and recycling questionnaire on the spot were conducted to investigate the cognition of ADR about 1 379 people from the Pearl River Delta,Eastern,Western and Northern region of Guangdong Province,and analyze related influential factors. RESULTS:Totally 1 500 questionnaires were sent out and 1 379 were effective with effective rate of 91.9%. Among the respondents,931(67.5%)could correctly answer the question of ADR concept, the correct rate showed lowest in the people lived in Northern region and with no less than 40 years old and low education;only 36.1% could correctly know the cause of ADR;only 388 (28.1%) knew the individuals can report ADR;723 (52.4%) thought hospital should be held responsible for ADR;once the ADR appeared,62.2% of respondents would choose to report to the hospi-tal. The main causes of discourage individual report of ADR were due to less know about where,how and which relevant depart-ments could report,and the report way was not convenient and the procedures were cumbersome. CONCLUSIONS:The public awareness of the ADR concept is not high and the enthusiasm of report is relatively low. Therefore,the propaganda of public aware-ness of ADR should be strengthened to encourage the public to participate in the ADR report actively,and broaden the channels of ADR personal report.

Background Dacryocystitis is one of the most common infectious eye diseases.The gold standard for the identification of bacteria causing dacryocystitis is bacterial culture.The combination of regular culture method with molecular biology techeniques will generate more reliable results.However,very few research data are available in ophthalmological studies in this area.Objective This study was to identify the genera and species of the dacryocystitis-causing bacteria by PCR amplification of the 16S rRNA sequences.Methods Ten cases of qualified standardized bacteria samples were taken,and the nucleic acids were released in the heating process of the PCR procedure.The 16S rRNA genes were amplified and sequenced,and the genera and species were identified using BLAST from GenBank,and the results were used to compare with the results from biochemical identification to test the reliability of this method.The cultured bacterial species from the lacrimal sac secretions from 30 cases of dacryocystitis patients were identified with the above method.Results The outcome of the PCR identification for the 10 cases of quality control standard bacterial specimens was consistent with the results from the biochemical identification.The identification of the 30 cases of dacryocystitis through sequencing the 16S rRNA revealed there were 13 cases of Staphylococcus epidermidis infection,2 cases of Staphylococcus warneri infection,1 case of Staphylococcus hominis infection,5 cases of Corynebacterium macginleyi infection,3 cases of Streptococcus pneumonia infection,2 cases of Bacillus cereus infection,1 case of Micrococcus luteus infection,1 case of Moraxella catarrhalis infection,1 case of Moraxella osloensis infection and 1 case of Pseudomonas aeruginosa infection.Conclusions Sequencing the 16S rRNA is an accurate and specific way for the identification of the genera and species of bacteria that cause dacryocystitis in patients.This sequencing method is feasible in monitoring a variety of dacryocystitis-causing pathogens.More information and epidemiological statistics about dacryocystitis can be obtained from 16S rRNA sequencing.

?DJ-1 has been reported to act as aredox-activated chaperone and sensor of oxidative stress participated in a variety of activities in cellular, playing an important role in resisting oxidative stress, regulating signaling pathways and gene transcription, and maintaining mitochondria dynamic balance. DJ -1 is closely related to the occurrence and development of various diseases. Recently, the effect of DJ-1 in eye diseases has drawn more attention, and researchers have found its significant role of resistance to oxidative stress in the pathogenesis of Fuchs endothelial corneal dystrophy ( FECD) and age-related macular degeneration ( AMD ) .This review will state the mechanism of DJ-1 against oxidative stress and its role in the development of eye diseases.

Objective To explore a safe and high efficiency way of gene transfection of autocrine motility factor(AMF) in order to provide experimental basis for transplantation of myoblasts carrying AMF gone. Methods Sprague Dawley rat myoblasts were cultured, purified, proliferated and immunohisto-chemically verified. Then, the myoblasts were transfected with AMF and eGFP (enhanced green fluores-cent protein) gene by FIV (feline immunodeficiency virus). Fluorescence microscope and laser scanning confocal microscope were employed to detect eGFP so as to verify positive transfection rate. Expression of AMF was detected by immunohistochemical method. Results Myoblasts with 98% purity could he ob-tained after two weeks of primary culture and purification. Positive transfection rate reached 90.4% when MOI (multiplicity of infection) was 100 (P <0.01). The transfected AMF gene could express normally. Conclusions Explant culture is a proper way in rat myoblast culture. Meanwhile, AMF gene can he effectively transfected into rat myoblast and well expressed via FIV.

Objective To investigate the HPV infection influence on the disease evolution of cervical intraepithelial neoplasia (CIN) .Methods 120 CIN grade Ⅰ patients diagnosed by under colposcopic biopsy pathology in 324th Hospital of PLA obstetrics and gynecology clinic from January to December 2010 were selected as the research objects ,concentrations of cervical secretions'HPV DNA were detected by hybrid capture two generations(HC-Ⅱ) of quantitative method .According to HPV infection ,patients were divided into CIN Ⅰ + HPV(-) and CIN Ⅰ + HPV(+ ) group and followed up for 3 years to obseve the disease evolution of CIN by means of TCT test and HR-HPV test .Results 13 .33% patients appeared disease progression in the CIN Ⅰ + HPV (-) group ,while 21 .67% in the CIN Ⅰ + HPV(+ ) group ,the difference between the two groups had significantly statistical difference (P<0 .05) .Conclusion HPV infection has an important role in the disease progression of CIN ,suggesting that the prevention and treatment of the HPV infection could slow down the progression of CIN .
10. Research status and progress of laboratory indexes related to neuromyelitis optica spectrum disorders
Medical Journal of Chinese People's Liberation Army 2020;45(5):573-578
Neuromyelitis optica spectrum disorders (NMOSD) is a group of inflammatory demyelinating diseases of the central nervous system characterized by recurrent optic neuritis or long-segmental myelitis, with high recurrence and disability. The discovery of aquaporin 4-immunoglobulin G (AQP4-IgG) distinguished the disease from multiple sclerosis (MS) and became an independent disease. T cells, B cells and complement system were involved in NMOSD pathogenesis. The levels changed of many cytokines and complements components in NMOSD patients' serum and cerebrospinal fluid, and the levels of other related laboratory indexes such as serum uric acid (UA) and thyroid hormone has also changed dynamically. The research status and progress of some laboratory-related indexes other than AQP4-IgG for NMOSD patients were reviewed in present paper, in order to provide new ideas for clinical diagnosis and prognosis evaluation of NMOSD, and reduce the rates of missed diagnosis and misdiagnosis.
