Food protein-induced enterocolitis syndrome(FPIES) is a series symptoms of recurrent vomiring and diarrhea caused by non-IgE-mediated food allergy to cow milk and soy in infants.The most common causative foods of FPIES are cow milk,soy and rice.Symptoms start within first days to 12 months of life.The sensitivity is usually outgrown by 3 years of age.The most common clinical symptoms observed include recurrent vomiting,diarrhea,fecal bloody,lethargy,pallor,etc.The diagnosis relies on history,clinical features,food eliminate,and oral food challenges.The food elimination is the mains treatment of FPIES management.

Objective To identify the reason and preventive methods from misdiagnosed cases of multiple myeloma(MM) initially manifested as lumbago.Methods Medical history and clinical data of 25 MM patients in department of hematology in our hospital were retrospectively analyzed to explore the clinical characteristics,misdiagnosis and prognosis of them.Results The 25 patients with initial presentation of lumbago were most misdiagnosed as bone and joint diseases,including 6 cases of lumbar disc,7 cases of lumbar compression fractures,6 cases of osteoporosis.And 1 cases of bone tuberculosis,3 patients of rheumatoid arthritis.And there were 2 cases of bone metastases,who were later diagnosed when anemia,neutropenia,thrombocytopenic and renal dysfunction appeared.The average misdiagnosed time was 7 months with a range of 3 months to 13 months.The median survival time was (29.2 ± 5.2) months in this group of patients.Conclusion MM,with the first manifestation of lumbago,has a single clinical manifestation and is often misdiagnosed as bone and joint diseases.Specialists who are not from hematology department should raise awareness and vigilance of the disease.Laboratory examinations results should be referred to in the diagnosis.Sum up experience in order to improve the early diagnosis of this disease and to effectively improve patient's prognosis and quality of life.

Early diagnosis,early treatment and the correct therapeutic approch are the keys for metastatic nasopharyngeal carcinoma(NPC) treatment.Currently,PET-CT is the best modality for distant metastasis staging of NPC.Cispalatin-based chemotherapy is the standard treatment method of metastatic NPC.Molecular targeted therapy is possible to further increase curative effect.When the lesions are limited,local palliative treatment may improve prognosis if patient's illness is controled by chemotherapy.

OBJECTIVE:To evaluate economic effectiveness of 3 kinds of antimicrobial drugs for acute lithiasic cholecystitis,and to provide reference for rational use of antimicrobial drugs in biliary disease surgery.METHODS:A multicenter prospective randomized controlled study was conducted in 493 clinical cases of acute lithiasic cholecystitis.Cost-effectiveness analysis of cefoperazone/sulbactam sodium(therapy A n=180),cefuroxime(therapy B n=148) and levofloxacin(therapy C n=165) for acute lithiasic cholecystitis were carried out.RESULTS:Effective rates of three kinds of therapeutic regimens 95.56%,73.65%,84.24%,respectively.CONCLUSION:Incremental cost-effectiveness analysis of three kinds of therapeutic regimens shows therapy A is economical and the best choice for acute lithiasic cholecystitis compared with group B and C.

Progress in Cocaine toxicology research,especially in i ts toxicological mechanisms on the central nervous and cardiac-cerebral vascular systems, was reviewed in the last 5 years.The main problems with the current resear ch work and the future research direction were pointed out.

The purpose of the medical moral education is to make medical undergraduates form stable feature of the medical moral education psychology.While the traditional medical moral education has not been achieving the aim.Many studies of psychology has presented that it is important for study,training and medical moral of medical undergraduates by using implicit learning.In order to achieve the aim and ensure the result of medical moral education.we should take advantage of implicit learning to develop the medical moral education.

A Review] The neuroendocrine-immunoregulatory network is fundamental to the maintenance of homeostasis. In this article, the authors present an overview of the role of neuroimmunoregulatory mechanism in the occurance and development of some diseases, which may have important therapeutic implication for the clinics.

Unregistered drug use,also called off-label drug use,has become a universal phenomenon in clinical practice worldwide.At present,there is still no definite laws and regulations in the field of off-label medication in China.The article gives an overview about the current criterion for prescription in China,the definition of off-label use,analysis of this situation and causes,how to regulate this practice to protect the patient's rights and safety,and also doctor's rights of prescription.

The p53 gene is one of the most common targets for genetic abnormalities in human tumors. Restoring wild - type p53 gene (wt-p53) into cancer cells which have p53 deletion is a strategy in cancer gene therapy. In order to explore the feasibility of this hypothesis, we selected a gastric cancer cell line BGC823 which was confirmed having deletion of chromosome 17pl3 and decreased expression level of p53 mRNA . We transfected construct pC53SN3 containing wt - p53 into BGC823 cell line with lipofectin mediated gene transferration, and G418 resistant colonies were characterized by using analysis of PCR, Southern blot hybridization, Northern blot hybridization and Western blot hybridization. These data showed that exogenous wt-p53 had successfully transferred into BGC823 cells and obtained high expression. The cell growth rates in regular medium and soft agar were inhibited from 30 to 40 percent in the BGC823 cells transfected with wt - p53. The tumorigenicity in nude mice showed that one of four mice failed to form tumor and three of them delayed to form tumor from 7 to 14 days comparing with monk and parent BGC823 cells. These results suggested that exogenous wt -p53 could suppress the growth ability and tumorigenicity of human gastric cancer cells. The method of using lipofectin mediated wt-p53 gene transfection may have a potentially therapeutic effect on human gastric cancer.

The effects of compound oral fish oil preparation on the increase of intelligence were studied. Step-down test, normobaric hypoxia test and loaded swimming test in mice were used. The results indicated that during the administration period (15 d and 30 d), the oral preparation containing fish oil 3. 6 g/kg and 7. 2 g/kg increased both learning and memory abilities, promoted the tolerance of normal mice to hypoxia as well as swimming fatigue.
