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.

Objective To identify the immunogenicity and the potential of using Schistosoma japonicum mitochondria related protein(rSj338) as a candidate vaccine antigen for Schistosomiasis japonica . Methods The expressed recombinant fusion protein(rSj338/26GST) was purified and recognized by S.japonicum heavily infected rabbit sera and rSj338/26GST immunized rabbit sera by Western blotting. The inclusion bodies,the revivified protein and the purified protein from S 12 gel filtration were injected twice into rabbits to produce anti rSj338/26GST antibody which titer was then measured by dot ELISA. Balb/c mice were immunized with the inclusion bodies and the purified protein from S 12 gel filtration and challenged with S. japonicum cercariae to identify the protective immunity produced by rSj338/26GST. Results The inclusion bodies, the revivified protein and the purified protein from S 12 gel filtration could stimulate the rabbits to produce high level of anti rSj338/26GST antibodies and could be recognized by S. japonicum heavily infected rabbit sera and rSj338/26GST immunized rabbit sera. In Balb/c mice, the inclusion bodies could induce 27.8%( P

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.

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

Rheumatoid arthritis (RA) is a systemic autoimmune disease with unknown etiology.The main feature of RA is chronic,symmetrical and invasive arthritis.RA may present with severe joint deformity and functional loss,which has higher disability and fatality rates.At present,no effective measures can reverse bone damage associated with RA clinically.Therefore,early diagnosis of RA is critical to improve prognosis.In recent years,imaging increasingly plays an important role in the early diagnosis of RA.This article reviews recent advances in imaging methods for early diagnosis of RA.

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.

OBJECTIVE: To investigate the mRNA and protein expression of MICA in laryngeal squamous cell carcinoma tissue and the Hep-2 cells. METHOD: Reverse transcriptase-polymerase chain reaction (RT-PCR) and Western-blot were used to detect the expression of MICA mRNA and protein levels in the Hep-2 cells and laryngeal cancer tissues. RESULT: The MICA mRNA showed higher expression in Hep-2 cells by RT-PCR. Compared with the control, the mRNA expression of MICA was significantly enhanced in laryngeal cancer tissues (t = 11.878, P < 0.01). The intensity of MICA expression is not related to the clinical stage of cancer. MICA protein demonstrated higher level expression by Western blot. The intensity of MICA protein expression was decreased with increased clinical stage in laryngeal cancer tissues. CONCLUSION The MICA mRNA showed stronger expression in Hep-2 cells and laryngeal cancer tissues. The intensity of its expression is not related to clinical stage of cancer. The MICA protein expression was strong in Hep-2 cells. The intensity of MICA protein expression was decreased with increased clinical stage in laryngeal cancer tissues. MICA may play an important role in laryngeal carcinoma process.

OBJECTIVE: To investigate the effects of tetrandrine (Tet) on nuclear factor kappaB (NF-kappaB) expression in leukemia cell line K562 and multidrug-resistant K562/A02 cell line. METHODS: The activations of NF-kappaB in K562 and K562/A02 cells and the effects of 1 micromol/L Tet on NF-kappaB expression were determined by immunocytochemistry and Western blot assay. RESULTS: Tet had no effect on NF-kappaB expression in K562 cells after 6- and 12-hour treatment (P>0.05), and K562/A02 cells displayed higher level of NF-kappaB protein expression than their parental K562 cells (P<0.01). Tet could significantly down-regulate NF-kappaB protein expression and nuclear translocation in K562/A02 cells shown by immunocytochemistry and Western blot, and this decrease became more significant after 12-hour treatment than after at 6-hour treatment (P<0.05). CONCLUSION: Activation of NF-kappaB may be related to multidrug resistance of K562/A02 cell line. And the inhibition of NF-kappaB activation by Tet leads to multidrug resistance reversal in K562/A02 cell line.

A novel method for accurate,fast and sensitive detection of pesticides such as imidacloprid,isocarbophos,phoxim,dursban,imidacloprid,pyridaben and avermectin in environmental water samples has been developed by using ultrasound-assisted dispersive liquid-liquid microextraction (UA-DLLME) coupled with high performance liquid chromatography with ultraviolet detection (HPLC-UV).The UA-DLLME parameters such as types/volumes of extraction/dispersion solvents,ultrasonic time,ionic strength and extraction time were investigated.Under the optimized extraction conditions,the linearity for the detection of six pesticides in the concentration range of 10-600 μg/L was obtained with limits of detections (LODs) of 0.8-3.1 μg/L and relative standard deviations (RSDs) of 4.7％-11.3％.UA-DLLME method exhibited strong enrichment ability for the six pesticides,and the enrichment factor (EFs) were ranged from 58 to 187.This method had perfect linearity,precision and recovery results,and showed obvious advantages and practicality comparing the previously reported methods.
