Equisetin (EQST) belongs to polyketide (PKS)-nonribosomal peptide synthetase (NRPS) type compound with an inhibitory effect of 11β-hydroxysteroid dehydrogenase 1 (11β-HSD1) enzyme activity. This study investigated anti-obesity effect and insulin resistance improvement effect of EQST on high-fat diet (HFD)-induced ob/ob mice model. EQST treatment effectively reduced the body weight gain, fat weight gain and blood lipid content of model mice. All animal experiments were approved by the Medical Ethics Committee of Capital Institute of Pediatrics. EQST alleviated adipose tissue expansion and hepatic ballooning degeneration of model mice, and also effectively controlled the blood glucose content after glucose load and insulin load, showed a significant improvement in obesity and insulin resistance. EQST inhibited adipogenic proteins fatty acid-binding protein 4 (FABP4) and peroxisome proliferators-activated receptor γ (PPARγ), and upregulated thermogenic protein (uncoupling protein 1, UCP1) through suppressing 11β-HSD1 protein expression. In addition, EQST widely upregulates mitochondrial respiratory metabolism related proteins in adipose tissue and may improve insulin resistance through phosphatidylinositol-3-kinase (PI3K) pathway. Therefore, EQST plays an anti-obesity role by promoting adipose tissue thermogenesis and improving insulin resistance, which may provide reliable clues for improving obesity and diabetes.

Objective To detect the expression of YB-1 and to research the relationship in the occurrence and development in the cervical squamous carcinoma(SCC) tissues.Methods Immunohistochemistry(IHC) envision was used to detect the expression of chronic cervicitis,CIN Ⅰ,CIN Ⅱ-Ⅲ and SCC.The relationship of YB-1 in the clinical pathological parameters of SCC were analyzed.Results YB-1 was mainly located in the nucleus in squamous cell,sometimes in the cytoplasm.The YB-1 protein did not expression in chronic cervicitis.In CIN Ⅰ,CIN Ⅱ-lⅢ and SCC,the positive expression had a gradual increasing trend.The expression of YB-1 was satistically significant in four groups (P＜0.05).The chronic cervicitis group,CIN Ⅰ groupCIN Ⅱ-Ⅲ group compared with the SCC group restivelly,the difference was statistically significant (P＜0.05).From spearman rank correlation analysis:the expression of YB-1 was positively correlated with the degree of cervical lesions (P＜ 0.05).In the cervical squamous carcinoma group,the expression of YB-1 was not associated with clinical pathological index of SCC patients(P＞0.05).Conclusion The change of the quantity of YB-1 protein is closely related to cervical squamous cell carcinoma.

Adenoid hypertrophy is a disease that mostly occurs among children of 3-5 years old. It is caused by repeated inflammation and infection of nasopharynx and its adjoin parts, or the adenoid itself, which will finally leads to pathological hyperplasia of adenoid. With so much information we have acquired about this disease, its specific mechanism remains unknown. In recent years, some researches have indicated that adenoid hypertrophy may have something to do with extra-gastroesophageal reflux, in which pepsin plays a very important role, and pepsin will do a series of pathological damages to the upper airway as it reaches the upper respiratory tract. Based on relative domestic and foreign literature, this paper attempts to make a review about the relationship between gastroesophageal reflux and adenoid hypertrophy.

Because the biology characteristic of HIV is extremely different from that of other microorganisms, HIV vaccine research has being faced with unprecedented difficulties and challenges. In the last 20 years, HIV vaccine research has been carried out mainly with two strategies, i.e., neutralizing antibody based and cellular immunization based; however, substantive breakthroughs haven't been achieved until now. Inducing effective neutralizing antibody is always an important strategy in traditional vaccine research, but this strategy is much less efficient in HIV vaccine research because of high variation and much subtypes of HIV. In recent years, the discovery of broadly neutralizing monoclonal antibodies and elucidation of their corresponding antigen epitopes have brought new hopes for the development of neutralizing antibody based HIV vaccine. Reviewing these advancements will be helpful for reconsidering HIV vaccine development with a better strategy.

OBJECTIVE: To establish an LC-MS method for identification of the primary degradation impurities in domestic calcitonin salmon injections. METHODS: For the RPLC analysis., the separation was performed on Waters XTerra RP C18 column (3.0 mm × 50 mm, 3.5 μm) with linear gradient elution using 0.05% aqueous trifluoroacetic acid (A) and acetonitrile (B); the flow rate was 0.5 mL · min-1; the column temperature was 40℃; the detection wavelength was set at 220 nm. For the SEC analysis, the separation was performed on TSK GEL 2000SWxl column (7.8 mm × 300 mm, 5 μm) with mobile phase consisting of TFA-water-acetonitrile(0.05:80:20); the flow rate was 0.7 mL · min-1; the column temperature was room temperature; the detection wavelength was set at 220 nm; the main impurities were collected and identified by positive mode. RESULTS: The structures of three impurities were elucidated by RPLC-MS and SEC-MS. CONCLUSION: The results of this study can be applied in impurity profile analysis, specification research, and quality control of calcitonin salmon injections.

Objective To summarize the tending physique of hysteromyoma patients and thus to provide the clinical prevention and treatment methods for the disease.Methods Clinical epidemiology investigation and study methods were adopted to design the unified investigation and study table.Questionnaire survey were performed stochastically to 150 hysteromyoma patients and 150 normal females.Various physique characteristics were recorded.Results Ecchymosis physique were commonly seen in hysteromyoma patients,accounting for 36.7％ in all patients.Conclusion The occurrence of hysteromyoma was closely related to ecchymosis physique.

Drug-induced nephrotoxicity is very common in both new drug development and clinic practice. Various drugs can induce kidney injuries, including tubulointerstitial, glomerular and renal vascular disease. To investigate the mechanism of drug induced nephrotoxicity is important for risk reduction of new drug development, reasonable drug usage, early discovery and effective prevention/treatment of adverse effects in clinics.

The effect of OQP, a pormula of traditional Chinese medieine belonging to the category "Precription of the Reinforeing Qi and Enriching Blood for keep the Original Qi", on cell strain of human hepatic carcinoma SMMC-7721 was observed. The results showed that OQP depressed the incorporation of both ~3H-TdR and ~(14)C-UR in cells of hepatic carcinoma. This indicated that OQP inhibited the synthesis of DNA and RNA, and the growth of the cancer cell. Such effect may result from the low ratio Cu/Zn and the high content of Se in OQP. In conclusion, in this study it has been demonstrated that OQP can not only improve the general condition of patients in advanced liver cancer and lcukopenia of patients in chemotherapy and radiotherapy, but also can inhibite the growth of the cell of hepatic carcinoma directly.
