MiR-200 family is a cluster of miRNAs closely linked to EMT. The miR-200 family contains miR-200a, miR-200b, miR-200c, miR-141 and miR-429. Many studies have shown that miR-200 family are key regulators of EMT and determine the epithelial phenotype. They are important to both EMT development and tumor progression. This paper reviews the advancement in the research of miR-200 family and its mechanism.

Objective To detect the protein expression of SHH and its downstream transcriptional factor GLI1 in Peutz-Jeghers syndrome (PJS) and to investigate the roles of SHH and GLI1 in the development and carcinogenesis of PJS polyps. Methods Immunohistochemical (IHC) staining was employed to detect the expression and localization of SHH and GLI1 protein in 20 PJS polyp samples, 25 adenomatous polyp tissues, 25 colon adenocarcinoma samples, and 20 normal intestinal mucosal tissues. Results IHC revealed that SHH protein and GLI1 protein were mainly localized on cell membrane and in the cytoplasm, and the nuclear staining of GLI1 protein in the colon adenocarcinoma was increased. The expression of the two proteins gradually increased in order in the normal intestinal mucosa, PJS polyp, adenomatous polyp, and colon adenocarcinoma (P<0. 001). Spearman rank correlation showed that SHH expression was significantly correlated with GLI1 expression in PJS polyp(rp =0. 503, P = 0. 024). Conclusion SHH-GLI1 is present in the tissues of normal intestinal mucosa, PJS polyp, adenomatous polyp, and colon adenocarcinoma, and the expression has an increasing tendency in the above tissues, indicating SHH-GLI1 signal pathway may be associated with the development and carcinogenesis of PJS polyp.

The metabolic syndrome leading to cerebrovascular disease attracts more and more attention by the medical circle,and its exact nosogenesis is not clear.There is no effective therapeutic method for this disease either.The author believes phlegm and blood stasis being the key factors for metaboric syndrome.Clinically,the author got good effects by treating the disease according to the different nosogenesis and stages of disease.

Long non-coding RNA ( LncRNA) is a class of transcript (>200 nucleotides) that do not encode proteins. It plays an important role in epigenetic regulation and gene expression at transcriptional or post transcriptional level. The abnormal expression of LncRNA may lead to various pathological processes. Diabetic retinopathy ( DR ) is a multifactorial disease. Recent studies have shown that many specific expressions of LncRNAs are closely related to the genesis of DR. In this review, we summarized the recent advances in the function of LncRNA, the regulatory mechanisms of LncRNA involved in the development of DR, and the related therapies.

Objective To explore the clinical effect of treatment for progressive multiple sclerosis(PMS)by autologous peripheral blood stem cell transplantation(APBSCT).Methods Between September 2001 and July 2004,thirteen patients with PMS were treated with APBSCT in Xuanwu Hospital.Peripheral blood stem cells (PBSCs)were mobilized with G-CSF alone.The stem cell transplants were pured of lymphocytes in 7 patients.The high dose regimen was BEAM conditioning regimen (Carmustine,Etoposide,Cytosine Arabinoside,and Melphalan).The median follow-up time was 22 (3～36)months.Results The result showed that the mean EDSS rating score of patients in 18 months after APBSCT was significantly decreased[(4.05?0.66) vs(6.00?0.30),P

AIM: To establish the quality standard for Compound Yiqi Granules (Radix Astragali, Radix Achyranthis Bidentatae, etc.). METHODS: Radix Achyranthis Bidentatae; Herba Epimedii were identified by TLC. The content of astragaloside IV in Compound Yiqi Granules was determined by TLCS. RESULTS: The methodological study showed a good linear correlation at the range of 1.12-5.60 ?g of astragaloside IV. The average recovery of astragaloside IV was 97.69% and RSD was 2.10%, respectively. CONCLUSION: The method is simple, accurate and with good repeatability. The method can be used for quality control of Compound Yiqi Granules.

Gonorrhea is a sexually transmitted disease caused by Neisseria gonorrhoeae,and substantially harms human health and socioeconomic development.Due to inappropriate treatment and the presence of drug resistance genes in patients,antibiotic resistance has emerged in Neisseria gonorrhoeae,such as resistance to penicillin,tetracycline,ciprofloxacin,or other antibiotics.Currently,extended-spectrum cephalosporins (ESCs) are the first-line treatment of gonococcal infection.With the wide use of ESCs,the sensitivity of Neisseria gonorrhoeae to ESCs has been decreasing gradually,and there have been reports on cases of treatment failure in clinical practice.In order to control gonorrhea and deal with drug resistance in Neisseria gonorrhoeae,combined therapy,alternative therapy and new drugs have been developed in clinic.

The present paper is to evaluate the scientific research level and development trends of biomedical engineering in China using metrology analysis on Chinese biomedical engineering scientific literatures. Pubmed is used to search the biomedical engineering publications in recent 5 years which are indexed by Science Citation Index, and the number and cited times of these publications and the impact factor of the journals are analyzed. The results show that comparing with the world, although the number of the publication in China has increased in recent 5 years, there is still much room for improvement. Among Chinese mainland, Hongkong and Taiwan, Chinese mainland maintains the obvious advantage in this subject, but Hongkong has the highest average cited number. Shanghai and Beijing have better research ability than other areas in Chinese mainland.
