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.

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.

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.

Early detection of HCC is critical for a good prognosis. Therefore, the development of tumor markers that can detect HCC at even earlier stages is urgent. Recent researches show that the human cervical cancer oncogene, gamma-glutamyl transferase mRNA, human telomerase reverse transcriptase mRNA, the proteins such as glypican-3, golgi protein 73, vascular endothelial growth factor and transforming growth factor-β1 could serve as markers for early detection of HCC.

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.

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.

Genome sequencing and bioinformatics is driving the discovery of drug targets and development of novel classes of broad spectrum antimicrobial compounds. The analysis of the complete genome sequences of microorganism available in the public databases offers the first insights into the drug targets discovery. This review discusses the use of genomic information in the finding of target genes for antimicrobial drug discovery.

Objective To investigate the rule of the aquaporin 4 (AQP 4) expression in the acute ischemic cerebral tissues, and to study the molecular biologic mechanism of diffusion weighted imaging (DWI). Methods Thirty six Wistar rats were divided into 2 groups randomly, including control group ( n = 12) and operation group ( n =24). The operation group was studied after the right middle cerebral artery was unilaterally occluded (MCAO) at an interval of 15 min, 30 min, 1 h, 3 h, 6 h, and 24 h, respectively ( n =4 for each sub group). The operation process of the control group was the same as the operation group except MCAO. All rats in both groups were examined with DWI. The relative ADC (rADC), relative density (rd), and relative area (rs) of the biggest hyperintensity signal layer on DWI were measured. After that, the animals were sacrificed and perfused with the mixture solution consisting of TTC at different time intervals. The biggest layer of the ischemic cerebral tissues stained with TTC and corresponding to that of DWI was examined with immunochemistry and in situ hybridization. The AQP 4 expression AQP 4 (△S and ?) was measured with the Image Analyzer. Meanwhile, histologic examination was performed at each group. Results There was no significant change of the DWI and the pathology, as well as the AQP 4 expression in the control group. In the operation group, abnormal high intensity was found in DWI of ipsilateral MCA territory at 15 min after MCAO, and rADC value decreased quickly within 1 h after MCAO, while the AQP 4 expression, the rd DWI, and the rs DWI increased rapidly in the stage. With the progress of the time, the rADC value further decreased at 3 h, and then began increasing slowly till 24 h . But the AQP 4 expression (△S and ?) and the rd as well as the rs continuously increased slowly between 1 h and 6 h after MCAO, then they had an increasing peak except the rd. The AQP 4 expression, rd DWI, and rs DWI all showed positive linear relationship with time, presenting as 2 peaks and a plateau. The corresponding sequential pathologic changes were gradual increase of intracellular edema (

Abstact: Biqiu is equivalent to allergic rhinitis in modern medicine. Ancient and modern literature has shown that acupuncture has a good clinical efficacy on this disease. However, there is no uniform specification in the choice of acupuncture methods (such as acupuncture, moxibustion, warm acupuncture and so on) and the selection of acupoints. According to the etiology and pathogenesis of allergic rhinitis and its clinical manifestations, Biqiu can be classified as“fluid retention disease”in TCM. This article tried to provide a new idea for acupuncture treatment of Biqiu from the perspective of the treatment of“fluid retention disease”in TCM.

With the aggravation of population aging and the change of social convention,especially after the introduction of two-children policy,some families wish to have two children can not be achieved due to various reasons.Therefore,they use assisted reproductive technology to achieve fertility aspirations.Surrogate is a controversial topic in the assisted reproductive technology,the contradictions between the normal reproductive rights of the infertile woman and the women who have lost their children but passed the age of childbearing and the bad ethical consequences and rights disputes of surrogacy.How to avoid the bad ethical consequences and meet the demand of reasonable surrogate is the major issue worthy to be discussed.
