OBJECTIVE:To study the characteristics and regularity of adverse drug reactions(ADR)occurred in our hospital.METHDOS:A total of 105 ADR cases collected from 2007 to 2008 in our hospital were analyzed statistically in respect of the reporters,sex and age of patients,drug categories,routes of administration,organs and systems involved and clinical manifestations.RESULTS:Of the 105 ADR cases,50.5% occurred in patients aged above 60,48.6% were induced by anti-infective drugs,72.4% were induced via intravenous route,and 34.3% manifested as lesions of skin and its appendants.CONCLUSION:Anti-infective drugs should be used rationally and ADR monitoring work should be emphasized to reduce or avoid the occurrence of ADR.

BACKGROUND: Contingent negative variation (CNV) is a kind of cerebral evoked potential, which is closely related with mental medicine and psychology.OBJECTIVE: To investigate the different manifestations between patients with affective disorder and normal adults in CNV detection.DESIGN: Case-control trial.SETTING: Department of Function, Psychiatric Hospital of Zibo, Shandong Province.PARTICIPANTS: Totally 29 inpatients and outpatients including 14 males and 15 females with affective disorder in the Fifth People's Hospital of Zibo between February 2005 and January 2006 were selected. The guardians were all informed and agreed the content; the diagnosed criteria of the patients were accorded wit h the criteria of DSM-Ⅳ. According to their mental status when hospitalized, the patients were divided into manic episode group and depressive episode group. There were 11 cases in the manic episode group, whose scores of Bech-Rataelson Mania Scale (BRMS)＞16; there were 18 cases in the depressive episode group, including unipolar depression (without history of mania episode) and bipolar depression (with history of mania episode) whose Hamilton Depression Scale (HAMD)scores ＞ 24. A total of 27 healthy hospital staff were selectedas control group including 14 males and 13 females aged 21-53 years and the mean age was (32.5±5.9) years. There was no significant difference in the age and sex among the three groups.METHODS: The CNV test was carried out in a soundproof room. Seating on a soft chair, the subject kept vigilant and focused on a fixed point in the front. The platinum electrode of 8 mm was attached to the subject's vertex Cz according to the International 10/20 System, referred to the right mastoid. The middle point of 2 eyebrows was grounded. The CNV waveforms were described by a L2-3 XY Functional Plotter. Standard CNV was composed of light signal and click signal. The flashlight and loudspeaker were located at the right back of the examinee. The subject was asked to press the button with his right finger to cut off the short sound as soon as his ears received the imperative click. It would take 2 500 ms for one CNV trial, and 20 trials as one experiment. Every subject was given the experiment for twice, and the standard amplitude was set by inputting a standard voltage of 20 μV to the same recording system.MAIN OUTCOME MEASURES: The CNV latency, amplitude B, area of negative expectancy wave before command signal, and area of negative change post-imperative negative variation (PINV) latency of the subjects in the two groups.RESULTS: All the 56 patients were involved in the result analysis.Compared with the control group, the mania group showed higher CNV amplitude [(22.8±4.8) μV; (16.0±5.7) μV; P ＜ 0.01], and the depression group presented smaller A-S2 area [(292.8±161.6)μV2; (412.8±159.9) μV2;P ＜ 0.01], and prolonged PINV latency [(261.9±79.3), (211.9±36.3) ms; P＜ 0.05]. The prolonged PINV latency was found in the unipolar depression group compared with the bipolar depression group [(344.5 ±66.9),(230.4±83.8) ms; P ＜ 0.01].CONCLUSION: CNV and PINV suggest that prolonged latency is the trait maker of the patients with unipolar depression, and CNV amplitude changes belong to the state makers of affective disorder.

The Streptococcus suis serotype 2 (S. suis 2) isolates 05ZYH33 and 98HAH33 have caused severe human infections in China. Using a strand-specific RNA-seq analysis, we compared the in vitro transcriptomes of these two Chinese isolates with that of a reference strain (P1/7). In the 89K genomic island that is specific to these Chinese isolates, a toxin–antitoxin system showed relatively high levels of transcription among the S. suis. The known virulence factors with high transcriptional activity in these two highly-pathogenic strains are mainly involved in adhesion, biofilm formation, hemolysis and the synthesis and transport of the outer membrane protein. Furthermore, our analysis of novel transcripts identified over 50 protein-coding genes with one of them encoding a toxin protein. We also predicted over 30 small RNAs (sRNAs) in each strain, and most of them are involved in riboswitches. We found that six sRNA candidates that are related to bacterial virulence, including cspA and rli38, are specific to Chinese isolates. These results provide insight into the factors responsible for the difference in virulence among the different S. suis 2 isolates.

The accurate diagnosis and precise prediction of tumor radiation sensitivity and normal tissue radiation-induced injury are the preconditions of precise radiotherapy for lung cancer.Radiomics is defined as a set of milestone,assistive tools in the develop-ment of precise treatment for lung cancer,which can extract many quantitative features from medical images by applying automatic or semi-automatic methods and determine the deep relationship between clinical diagnosis and treatment data.Thus,the occurrence, development,and clinical outcome of lung cancer may be revealed.Radiomics holds immense potential in the classification of benign and malignant lung nodules,prediction of lung cancer genetic phenotypes,and treatment response to radiation therapy,because it can obtain information regarding the global heterogeneity of tumors via a noninvasive approach.In the present review,we summarize the latest process of CT-based radiomics in precise radiotherapy for lung cancer.
