OBJECTIVE:To provide a reference for further strengthening the supervision and administration of the management and use of Papaver somniferum. METHODS:The general information,clinical application and toxic reactions of P. somniferum were briefly described by reference to relevant literatures and on the basis of the actual work. According to current laws and regula-tions,the existing problems about the clinical application and management of P. somniferum were revealed,and relevant counter-measures and suggestions were put forward. RESULTS&CONCLUSIONS:Both toxic and addictive,P. somniferum is the only tra-ditional Chinese herbal medicine covered by narcotic drug management. It is mainly used in clinical practice to relieve cough,diar-rhea and pain,etc. Although relevant laws and regulations have provided the specific requirements for the production,purchase, use and research & development of P. somniferum,slack enforcement of the laws and regulations,irrational use and abuse still ex-ist. It is suggested that State Food and Drug Administration and health administrative departments should constantly improve rele-vant law and regulation system and detailed regulations,strengthen supervision and administration,and strictly enforce relevant laws and regulations at the units engaged in the production,management and use of P. somniferum. Meanwhile,competent authori-ties should strengthen publicity and training.

Before and after artificial immunotherapy (desensitization) for midge dermatitis, the authors determined immunologic status of some patients.It was found that their functions of cell-mediated immunity were lowered, manifesting as decreased number of Ts lymphocytes, raised circulating IgG level, decreased total hemolytic complement, and significantly increased immune complex positive rate.At the end of therapy, the number of Ts lymphocytes and total hemolytic complement rose. The authors consider that the lowered function of cell mediated immunity plays an important role in the pathogenesis of midge dermatitis.In addition to type Ⅰ and Ⅳ hypersensitivity, type Ⅲ hypersensitivity may also be present because of the increased immune complex positive rate.

A biosensor is made from a biological sensing element attached to a signal transducer.Biosensors have many outstanding virtues such as portable,simplicity of operator and lowconsumption.Also,biosensors could provide fast,real-time and accurate results.Therefore,biosensors have been implemented for a number of applications in molecular diagnostics.We have summarized the recent progress in the research and application of biosensors in the field of molecular diagnostics for pathogenic micro-organism,drug testing and genetics.

MicroRNAs (miRNAs) are a class of small single-stranded noncoding RNAs which are involved in regulating many physiological and pathological processes.The rapid detection of miRNA is of great importance for the function of miRNAs.In comparison with traditional methods,the biosensor has the advantages of simple operation,rapidness,high sensitivity,and real-time detection.Thus,biosensors have been implemented for a number of applications in miRNA detection.

Tuberculosis a disease with the highest death rate by single pathogenic infection can cause serious harm to human health .MicroRNA ( miRNA ) is a classical single-stranded, short RNA molecules ( about 21 to 25 nucleotides ) that plays an important role in cell proliferation , differentiation , senescence and apoptosis by inhibiting the post-transcriptional gene expression or promoting degradation of target gene mRNA . Recent studies have shown that miRNA involved in the regulation of apoptosis , expression of pro-inflammatory cytokines , inflammation-related signaling pathways in tuberculosis infection . Meanwhile, miRNA may be a new biomarker for tuberculosis diagnosis.

Molecular transport controls the efficiency of complex biological network systems such as cellular signaling system and cascade biomedical reaction. However, device fabrication for molecular sensing is often restricted by a low transport effciency and complicated processing. Here, we report a molecular threading dependent transport system using three-dimensional (3D) paper origami enabling the directional transport of biomolecules. We demonstrate that framework nucleic acid based interface engineering allows orthogonal molecular recognition and enzymatic reaction with programmed order on site. We thus develop a single-step electrochemical DNA sensor for quantitative analysis with 1 picomolar sensitivity within 60 min. Our sensor can discriminate a mismatched target at the level of a single base mismatch. Our study shows a great potential toward the development of a biomimetic molecular transport system for point-of-care and precision diagnosis.

Objective To analyze the lipid levels in liver damage.Methods 82 patients with liver damage were divided into the study group(41 patients)and control group(41 patients),the control group patients were given treatment of atorvastatin,while the study group patients were given treatment of Zhibitai,the lipid metabolism of the two groups were compared.Results In the study group,levels of TC (5.16 ±0.8)mmol/L,TG(1.90 ±0.08)mmol/L,LDL(2.03 ±0.11)mmol/L were significantly lower than before treatment TC(5.82 ±1.26)mmol/L (t =4.38, P <0.05),TG(2.16 ±0.85)mmol/L (t =6.37,P <0.05),LDL(3.67 ±0.09)mmol/L (t =6.42).The HDL level (1.39 ±0.26)mmol/L was significantly increased (0.86 ±0.21)mmol/L (t =7.52,P <0.05)after 4 weeks treat-ment(P <0.05).The incidence of adverse events in the study group (7.3%)was significantly lower than the control group (17.1%)(P <0.05).Conclusion Zhibitai is safe and effective with use value in the treatment of liver dys-function.

Pulmonary fibrosis is a group of chronic lung diseases induced by various causes. Because of its complex etiology and pathogenesis,most of the pulmonary fibrosis diseases have no effective treatment currently and the quality of life and prognosis of patients are poor. Recent studies on biomarkers of susceptibility and effect associated with pulmonary fibrosis have made great progress, which is of great significance for screening and early diagnosis of the disease,and even for the evaluation of therapeutic efficacy and prognosis. This paper reviews some potential biomarkers of pulmonary fibrosis diseases,including the mucin 5B promoter variant and matrix metalloprotease-7 associated with idiopathic pulmonary fibrosis,heme oxygenase-1 and serum Se related to silicosis,Krebs von den Lungen-6,surfactant proteins-D and sphingolipids signaling associated with various pulmonary fibrosis, in order to provide new ideas for further research on the prevention and treatment of pulmonary fibrosis diseases.

Objective: To observe the clinical efficacy of Nie-pinching the spine, puncturing Sifeng (EX-UE 10) plus Chinese herbs in treating pediatric anorexia due to dysfunction of spleen in transportation. Methods: A total of 64 kids were randomized into an observation group and a control group by the random number table method, with 32 cases in each group. Patients in both groups received Jian Pi Kai Wei (strengthening spleen and stomach) powder according to pattern differentiation of traditional Chinese medicine (TCM). In addition, patients in the observation group received Nie-pinching the spine and puncturing Sifeng (EX-UE 10). Nie-pinching the spine was applied twice a week, and puncturing Sifeng (EX-UE 10) was performed once a week, with 2 weeks counted as 1 course of treatment. After 2 courses of treatment, the body mass index (BMI), peripheral blood leptin level and the microelements Zn, Fe and Se were compared at different time points (before treatment, after the first and second courses of treatment), as well as the therapeutic efficacy and onset time. Results: After 2 courses of treatment, 31 cases in each group were evaluated. After the 1st course and the 2nd course, the BMI and serum Zn, Fe and Se levels in the observation group increased significantly (all P<0.05), the leptin level decreased substantially (both P<0.05); the BMI in the control group showed a substantial rise (P<0.05), while the Zn, Fe and Se levels slightly increased showing no statistical significance (all P>0.05), and the leptin level decreased but the difference showed no statistical significance (P>0.05). After the 1st and the 2nd courses of treatment, the BMI, serum Zn, Fe and Se levels increased more significantly (all P<0.05), and the serum leptin level decreased more significantly (both P<0.05) in the observation group than in the control group. After the 2nd course, the total effective rate and recovery rate in the observation group were both higher than those in the control group (both P<0.05), together with a quicker onset time (P<0.05). Conclusion: Nie-pinching the spine, puncturing Sifeng (EX-UE 10) plus Chinese herbs is effective for pediatric anorexia due to dysfunction of spleen in transportation. It can decrease leptin, increase Zn, Fe and Se levels, alleviate apositic symptoms and increase BMI in the kids.
