ABSTRACT
The paper comprehensively understands the current construction situation of 30 provincial disease control websites through scientific evaluation methods and professional evaluation indexes,and finds and analyzes the major problems.The result shows that the website construction of disease control system is in the development phase generally,information publication and online service is provided with certain foundation,but the mutual communication and website design are relatively weak links which can be greatly improved.
ABSTRACT
Background:The incidence of ischemic colitis(IC)is increasing in recent years with the aging of population,and the rate of delayed diagnosis or misdiagnosis is high because of the lacking of specific clinical characteristics. Aims:To study the clinical characteristics of IC so as to improve its early diagnosis and treatment. Methods:The clinical and endoscopic characteristics of 75 IC patients from Jan. 2009 to Dec. 2014 at Urumqi General Hospital were retrospectively analyzed. Results:IC usually occurred in elderly patients with age ≥60 years,females were more common. Most patients had underlying diseases,including hypertension,coronary heart disease,diabetes,hyperlipidemia and arrhythmia,etc. Colonoscopy and medications could also induce IC. The main clinical presentations were abdominal pain,hematochezia and diarrhea. The lesions were mostly located in left colon and of the transient type. Conclusions:IC should be suspected when elderly patients with underlying diseases,complaining abdominal pain,hematochezia and diarrhea,colonoscopy and pathologic study should be undertaken as early as possible. Prognosis is good when treated timely.
ABSTRACT
Ebola virus-related papers covered in PubMed and CNKI were analyzed by co-occurrence and cluster analysis, respectively. The current situation in research of Ebola virus in China and foreign countries was com-pared. Some suggestions were proposed for research of Ebola virus in China, such as attaching importance to re-search of Ebola virus, enforcing research of its vaccine,and strengthening cooperation between domestic and foreign scholars.
ABSTRACT
Objective: To observe the targeting therapy of the hdsFv-RC-RNase recombinant single chain immunotoxin on the xenograft of the human hepatocellular carcinoma in nude mice and to explore its clinical potentiality. Methods: The prokaryotic expression vector TIG-hdsFv-RC-RNase was transformed into E.coli BL21(DE3)plys to largely express recombinant single chain immunotoxin hdsFv-RC-RNase against hepatocellular carcinoma induced by IPTG. The expressed product was purified via Ni-NTA affinity chromatography under native conditions and mildly refolded. The ELISA was used to analyze its immunological activity of antigen-binding capability. The xenogrft model of the human hepatocellular carcinoma in nude mice was established and the targeting therapy of hdsFv-RC-RNase was evaluated. Results:After induced by IPTG, a new protein band with M_r 41 000 was found in the supernatant of the bacteria and expressed in a soluble form. The expressed product was purified to homogeneity via Ni-NTA affinity chromatography under native conditions. The results of ELISA showed the refolded hdsFv-RC-RNase had the specific antigen-binding capability to the human hepatocellular carcinoma cell, but not to the normal hepatocyte (P
ABSTRACT
OBJECTIVE:To discuss the general pattern and characteristics of adverse drug reactions (ADR) induced by rabies vaccine. METHODS: A total of 156 ADR cases induced by rabies vaccine were retrieved from China Hospital Digital Library and China Pharmaceutical Abstract between Jan. 1995 and Nov. 2008 and analyzed statistically. RESULTS: The ADR induced by rabies vaccine were more often seen in females aged from 1 year to 40 years. 43.59% occurred within 30 minutes after medication;94.87% manifested as allergies,and allergic shock was even noted in serious cases. CONCLUSION: Great importance should be attached to the ADR induced by rabies vaccine to ensure medication safety.
ABSTRACT
AIM To investigate the effect of oral roxithromycin on serum concentrations at steady state and its pharmacokinetics of aminophylline in New Zealand rabbits. METHODS The experiment was divided into 2 stages: (Ⅰ) The subjects only received a four-day course of oral aminophylline until steady-state; (Ⅱ) aminophylline and roxithromycin were coadministrated from the d 5～10. After the last dose of aminophylline at the end of each study stage, serum theophylline concentrations were determined with HPLC. RESULTS Compared to stage Ⅰ, AUC、CL/Fs、 K a、 K e、 T 1/2(ka) 、 T max had significantly changed or very significantly changed at stage Ⅱ ( P
