Children with plastic bronchitis,characterized by unknown origin,insidious onset,rapid progress,severe symptom and high mortality,is a relatively rare disease.Also,it is difficult to diagnose and treat with plastic bronchitis characterized by marked airway obstruction,via the formation of large gelatinous or rigid airway cast.It is associated with certain diseases including bronchial asthma,cystic fibrosis,accompanied with acute chest syndrome with sickle cell disease,congenital heart disease and bacterial and viral respiratory infection.Clinicians should be aware of this disease,and early bronchoscopy should be intervened.

Fatigue is one of the most common complaints in cancer patients that profoundly affects all aspects of quality of life.However,cancer-related fatigue remains under recognized and poorly treated.This rcview has been conducted with the causes and potential treatments of fatigue in cancer patients.The methods for evaluating fatigue,and possible therapeutic options are also discussed.

Retinal ischemia-reperfusion injury (RIRI) is a common pathological and physiological clinical oculopathy,which can occur in retinal artery and vein occlusion,diabetic retinopathy and acute angle-closure glaucoma.The resulting ischemia can cause cell metabolic dysfunction,serious retinal damage and descending visual function.RIRI is the result of multiple factors.The currently accepted hypotheses mainly include the injury effect of oxygen-derived free radicals,intracellular calcium overload,the action of leucocyte and apoptosis.However the protection and treatment research in the RIRI is limited.The present paper reviews the progression in the drug intervention of RIRI.

Objective To design a new pre-treatment device and to evaluate its efficiency in order to monitor the tritium levels in biological samples.Methods The detection efficiency of tritium was determined with standard tritiated water.Recovery of tritiated water and organically bound tritium (OBT) were detected with high, medium and low activities of standard tritiated water and 3H-TdR (tritiated thymidine), respectively.Comparison of three kinds of biological samples using different pre-treatment devices was shown.Results The standard curve can be used in environmental tritium measurement and the detection efficiency for tritium was 23.3%.When 40.0 g rice with standard HTO or 3H-TdR was pretreated with this device, the average recovery of HTO and OBT was about 95.4% , which showed good reproducibility.The comparison results were similar.Conclusions The pre-treatment device can be used to survey the OBT in environmental biological samples.

Objective To assess the association of interleukin-6 (IL-6)-174C/G and-572C/G gene polymorphisms with hy-pertension risk.Methods The electronic databases,such as Pubmed,Web of Science,Google scholar,China National Knowl-edge Infrastrure and Wanfang database were searched by the interleukin-6,polymorphism,IL-6,hypertension,high blood pressure as the keywords/abstract.Random effect model was used to calculate the pooled odds ratio.Results The meta-a-nalysis included 6 studies with 1 041 hypertension cases and 1 088 health subjects,which was no significant association be-tween IL-6-174C/G gene polymorphism and hypertension (C vs G:OR=0.50,95%CI=0.22~ 1.14,P =0.10),and in the stratified analysis by ethnicity,no significant was found in Asian subgroup (C vs G:OR=0.75,95%CI=0.41~1.38,P =0.36).There was also no association between IL-6-572C/G gene polymorphism and hypertension in Asian (C vs G:OR =0.76,95%CI=0.51~1.15,P =0.20).Conclusion The IL-6-174C/G and-572C/G gene polymorphisms were suggested to be no related to the increased risk of hypertension in Asian.

Objective:To study the extraction process of AWei capsule.Methods:Taking the contents of gallic acid and the yield of extracts as assessment index to optimize water extraction process of AWei capsule with orthogonal experimental design.Taking the contents of magnolol,honokiol and the yield of extracts as assessment index to optimize ethanol extraction process of AWei capsule with orthogonal experimental design.Results:The optimal water extraction process of AWei capsule was extracting twice,every time lasted 1.5h,every time added 14 times water.The optimal ethanol extraction process of AWei capsule was using 80%ethanol as solvent,extracting twice,every time lasted 1.5h,every time added 6 times solvent.Conclusion:The optimized extraction process is stable and reasonable.

OBJECTIVE:To evaluate the present situation and trend of the antidepressants.METHODS:The antidepres?sants drugs in21hospitals of Hangzhou during2000～2003was statistically analyzed with respect to sales sum,market struc?ture etc.RESULTS:The total amount for antidepressants increased dramatically year by year.The consumption of the im?ported antidepressants has been decreasing while that of the domestic has been increasing and that of the antidepressants from the joint ventures remained stable.CONCLUSION:There is a great potential for the development of antidepressants;the sales amount and the consumption sum take on a trend of increasing rapidly.

Dermatovenereology have developed rapidly in fields including genodermatology, dermatological epidemiology, skin immunology, infectious skin diseases, clinical diagnosis, drug treatment, light therapy, and sexually transmitted diseases in recent years. Meanwhile, many skin diseases and a few venereal diseases still lack effective ways of treatment and control. More efforts should be made in both basic and clinical researches in the related fields.

Ductal carcinoma in situ belongs to the early stage of breast cancer.The treatment of ductal carcinoma in situ is similar with that of the breast cancer.Because of the low mortality rate in patients with ductal carcinoma in situ,there was an excessive treatment in the treatment of ductal carcinoma in situ.So the key to the treatment of ductal carcinoma in situ was to improve the quality of life.The present study shows that the effect of conserving surgery with radiotherapy is same with mastectomy's in the treatment of breast ductal carcinoma in situ.Sentinel lymph node biopsy can also be used to evaluate the patient's axillary status.For patients with ductal carcinoma in situ with breast conserving surgery,radiotherapy and endocrine therapy can reduce the recurrence rate of ipsilateral breast cancer.Radiotherapy and endocrine therapy have also become the standard treatment for ductal carcinoma in situ.
