Objective To investigate the effect of asperuloside(ASP)on the malignant progression and chemotherapy resistance of hepatocellular carcinoma(HCC)cells by regulating the supersonic hedgehog(SHH)/glioma-associated oncogene homolog 1(GLI1)signaling pathway.Methods The expression of SHH and GLI1 protein in human hepatocellular carcinoma cell line(SMMC-7721)/adriamycin(ADM)and SMMC-7721 cell line were detected by Western blot(WB).The HCC drug-resistant cell line SMMC-7721/ADM were divided into Control group,ADM group,L-ASP group(1 mmol/L ASP),M-ASP group(2 mmol/L ASP),H-ASP group(3 mmol/L ASP),ASP+PM group(1 μmol/L SHH/GLI1 signaling pathway activator PM).Ex-cept for Control group,5 μg/mL ADM was added to each group.The effect of ASP on the proliferation of SMMC-7721/ADM cells was detected by cell counting kit-8(CCK8)assay and plate cloning assay.The effect of ASP on the invasion and migration of SMMC-7721/ADM cells were detected by Transwell assay.The effect of ASP on the apoptosis of SMMC-7721/ADM cells was detected by flow cytometry.The expression of SHH,GLI1,proliferating cell nuclear antigen(PCNA),matrix metalloproteinase-9(MMP-9)and B cell lymphoma-2 associated X protein(Bax)in SMMC-7721/ADM cells were detected by WB.Animal experiments verified the effect of ASP on the growth of HCC xenografts and the expression of SHH/GLI1 signaling pathway proteins.Results The expression of SHH and GLI1 in SMMC-7721/ADM cells were higher than those in SMMC-7721 cells(P＜0.05).L-ASP group,M-ASP group and H-ASP group decreased the proliferation,migration and in-vasion of SMMC-7721/ADM cells in a dose-dependent manner,decreased the expression of SHH,GLI1,PCNA and MMP-9,and promoted cell apoptosis and Bax expression(P＜0.05).SHH/GLI1 signaling pathway acti-vator PM could reverse the inhibitory effect of H-ASP treatment on malignant progression and chemotherapy resistance of SMMC-7721/ADM cells(P＜0.05).ASP could inhibit the growth of HCC transplanted tumor and the expression of SHH and GLI1(P＜0.05).Conclusion ASP can inhibit the malignant progression of HCC cells and enhance the sensitivity of chemotherapy,which may be achieved by inhibiting the SHH/GLI1 signaling pathway.

Objective: To investigate the relationship between the erythrocyte membrane protein gene mutations and the clinical severity of hereditary spherocytosis (HS). Methods: Targeted sequencings were performed on 25 HS patients, correlation between HS mutations and patients’ clinical characteristics were evaluated. Results: A total of 25 HS patients were enrolled, including 13 males and 12 females with median age of 20 (4-55) years, including 9 compensatory hemolysis patients, 9 patients with mild anemia, 3 patients with moderate anemia and 4 patients with severe anemia. Of them, 18 patients (72%) harbored HS-related mutations, including ANK1 mutation in 6 cases, SLC4A1 mutation in 6 cases, SPTB mutation in 5 cases and 1 case with EPB41 mutation. Seven patients (28%) didn’t carry common HS mutations. SPTB and SLC4A1 mutations mainly affected male patients. There was no significant difference between the age of diagnosis (P=0.130) and HGB level (P=0.585) in patients with HS mutation and those without mutation, however, the EMA binding fluorescence intensity (P=0.015), AGLT50 (P=0.032) and EOF minimal hemolytic concentration (P=0.027) were significantly different in these two groups of HS patients. Conclusion To screen erythrocyte membrane protein coding gene mutations could favor the diagnosis of HS, and patients without mutations have mild clinical phenotype.

Objective:To assess the clinical use of dezocine injection. Methods:The application of dezocine injection in the in-patients during December 2015 and November 2016 in a hospital was statistically analyzed and evaluated from indications, dosage, treatment course and combined drug use, etc. Results:A total of 12847 patients with the age range of 0-97 and the average age of (49 ± 15. 6) years old were treated with dezocine injection. The top three departments using dezocine injection were orthopaedics (12. 70％), hand surgery (10. 30％) and liver surgery (9. 39％). Totally 132 patients were with overdose(1. 03％), and mainly in cardiac surgery. The medication course of 1042 patients was more than one week(8. 11％), which was too long, while most of the pa-tients were with tumor. Conclusion:The clinical use of dezocine injection in the hospital is basically reasonable. However, clinicians still need more training to minimize the risks involved in the process of clinical medicine application.

AIM: To investigate the role of phosphoinositide pathway in the formation of pressure-overload cardiac hypertrophy. METHODS: Cardiac hypertrophy was induced in male Sprague-Dawley rats with coarctation of abdominal aorta, whole heart weight/body weight ratio was tested after 10 or 30 days of operation. Content of G?q/11 protein in left ventricle was detected by immunoblot analysis and concentration of IP 3 was measured by radioimmunoassay. RESULTS: At 10 and 30 days, whole heart weight/body weight ratio of coarctation aorta (CA) group was higher than that of sham-operated (SO) rats ( P 0.05). At 10 days, the level of IP 3 significantly increased in left ventricle of CA rats compared with the control animals ( P
