AIM: To examine the effect of insulin on the proliferation of human hepatocellular carcinoma cell and its possible mechanisms. METHODS: The human hepatocellular carcinoma cell line(HepG-2) was used to study the changes in calcium ion across plasma membrane (Ca 2+ APM)under the action of insulin by the assay of atomic absorption spectrum, and in the proliferation under the action of insulin and calcium ion antagonist (isoptin). RESULTS: The influx of Ca 2+ APM and the proliferation was increased after insulin administration, but the proliferation was inhibited by isoptin. CONCLUSION: Changes in the homeostasis of calcium ion across plasma membrane was involved in the effect of insulin on the proliferation of human hepatocellular carcinoma.

Objective To investigate the clinical application of ultrasound-guided percutaneous puncture aspiration and sclerotherapy of liver hydatid cysts.Methods Thirty-eight patients of hepatic hydatid cysts underwent ultrasound-guided percutaneous puncture aspiration and sclerotherapy;then 20%-25%septic hypertonic saline or 95%absolute alcohol were injected into the cysts (the volume was about 25%-50%of the aspirated fluid) ;and the fluid was reaspirated after 5-15 min.At last,5-10 ml sclerosing agent was injected again.Oral albendazole 30-50 mg/kg was administrated to all patients before and after the above procedures.Ultrasonic follow-up was performed at 3-month interval in the first year and once a year afterwards.Results The successful rate of once puncture was 100%.Aher 6 months,cysts volume reduced 50% in 16 patients,reduced 30% in 22 patients.One year later,34 patients were cured,3 were effectively treated and 1 was improved.All hydatid cysts volume gradually decreased and calcification occurred.The total cure rate was 100%. Conclusion Ultrasound-guided percutaneous puncture aspiration and sclerotherapy is a safe,effective and reliable treatment of liver hydatid cysts.

BackgroundIn an ideal eye there would be no light scattering at all,but the eye media is not optically ideal.Intraocular straylight causes a veil of light and reduction in the contrast of the retinal image and thus decrease the quality of vision.ObjectiveThe present study was to investigate the repeatability and reproducibility of C-Quant straylight meter( Oculus,Germany)in measuring retinal straylight of myopia and post-laser in situ keratomileusis(LASIK) corneas.MethodsThis is a prospective research.The consecutive 35 eyes of 21 myopic patients and 34 eyes of 22 patients who received LASIK were included in this trail.Retinal straylight was measured for 7 times at a period of time and analyzed quantificational to evaluate the repeatability of measurement.Thirty-eight eyes of 19 patients were measured again at 3-7 days for 3 times at a period of time to assess the reproducibility of C-Quant straylight meter.The mean standard difference (SD) and coefficient of variation (CV) were used as the credibility evaluation.This clinical study complied with Helsinki Declaration and the informed consent was obtained prior to the medical procedure.ResultsThe straylight Log(s) of 7 times measurement were all less than 0.95.The mean Log(s) were 0.92±0.12 and 0.93±0.17 respectively in myopia group and post-LASIK group,without statistically significant differences among 7 times measurement( F=0.335,P=0.812;F=1.000,P=0.409).The mean SD for the 7 times measurement was 0.07 Log units.SD and CV increased with the number of measurements.The differences of mean SD and CV between 3 times result and 6 times result were significant different (t =-2.080,P =0.045;t =-2.190,P =0.035 ).No difference was found between different time periods( t =-0.531,P=0.598 ).The difference of the results between two measurements from the same patient was 0.013.ConclusionsC-Quant is a noncontact,noninvade,rapid and convenient method for the measurement of straylight in myopia and post-LASIK eyes due to the high repeatability and reproducibility.

ObjectiveTo study the present human resources of TCM hospitals in China, for decision making of TCM hospitals HR strategy in the future. Methods Collection of statistics released by the Ministry of Health and the State Administration of Traditional Chinese Medicine from 2005 to 2009, for analysis of the general structure and trends of hospital staff at large, headcount and makeup of medical personnel, and the structure and trends of TCM professionals in TCM hospitals. Results In 2009, there were 2,728 TCM hospitals, employing 518, 5000 staff, including 427, 900 medical personnel, accounting for 82.52％ of the total; TCM practitioners account for 45. 61％ of clinicians in TCM hospitals;a shortage of nursesisfoundin TCM hospitals as comparedto general hospitals. ConclusionIt is imperative to revise the staff quota standard of TCM hospitals, and to increase the number of TCM practitioners and nursing staff in TCM hospitals.

Andrographolide total ester sulfonate (ATES) injection is one of the products of traditional Chinese medicine (TCM) currently used against viral infection in China.ATES injection was approved for manufacturing and marketing in January 2002.It is indicated for acute respiratory infections,tonsillitis,chronic obstructive pulmonary disease,influenza,foot and mouth disease,bronchiolitis,herpangina,mumps,infectious mononucleosis and psychosis.However,its usage also carries risk.We investigated the use of ATES at the Wuhan Union Hospital from January 2014 to December 2014 and evaluated its real-word clinical application using the hospital centralized monitoring method.A total of 848 cases were enrolled in this study.In these cases,it was mainly used for postoperative anti-inflammation and treating upper respiratory infection,pneumonia and bronchitis.Among them,39.86％ were contraindicated.Irregular medication of adults and children accounted for 1.91％ and 23.38％,respectively.Improper choice of solvent accounted for 3.18％.The choice of intravenous drip versus aerosol inhalation was reasonable.A case of adverse events (AEs) was observed in the monitoring period,and the incidence of adverse drug reaction (ADR) of ATES injection was 0.12％.ATES injection in our hospital is relatively safe with a low incidence of adverse reactions.The study assesses the clinical usage and adverse reactions of ATES injection,and provides suggestions for rational use in clinical practice.

The interaction between Gliotoxin and bovine serum albumin (BSA) was studied by the fluo-rescence, Circular Dichroism (CD) and ultraviolet visible (UV-Vis) techniques. The fluorescent experiment showed that the intrinsic fluorescence of BSA was quenched by the binding of gliotoxin in a static quenching procedure, with an association constant of 7.2?103 L/mol and in hydropobic forces. And the CD spectrum revealed that gliotoxin effected the conformation of BSA by increased the mass of ?-helix.

Objective To investigate the expression of osteopontin and matrix metalloproteinase-9 (MMP9),and the relationship of osteopontin and MMP9 in malignant melanoma.Methods Expression of osteopontin and MMP9 was measured by immunohistochemical SP method in 23 patients with primary cuta- neous malignant melanoma,17 patients with metastatic melanoma and 20 patients with pigmented nevus. Results Osteopontin and MMP9 were expressed respectively in 87.5% and 75.0% of 40 malignant melanoma specimens,15.0% and 10.0% of 20 pigmented nevus specimens.The expression of both osteo- pontin and MMP9 was significantly higher (both P＜0.05) in malignant melanoma than in pigmented ne- vus.There was no correlation between the expression of osteopontin and MMP9,with age,sex,lymph node metastasis or location of lesions (P＞0.05).Twenty-nine cases were positive for both osteopontin and MMP9,4 negative for either osteopontin or MMP9.Conclusion Both osteopontin and MMP9 were over- expressed in malignant melanoma,but neither was related to lymph node metastasis.

Chronic liver diseases can further develop to liver fibrosis and cirrhosis. Currently, there is no effective treatment except liver orthotopic transplantation at this point. The extreme shortage of liver organ source forced people to find alternative treatment strategies. Mesenchymal stem cells ( MSCs) have the abilities of immunomodulatory, hepatocyte differentiation, promotion of liver cells regeneration in situ and inhibiting the activation of hepatic stellate cells. Therefore, MSCs transplantation provides a very broad prospect for cell therapy. It is important to provide preclinical evaluation of the efficacy and safety before the application of cell therapy in clinical trials. The progress of various animal models of human liver diseasees and significance of using MSCs to treat liver diseases in preclincal studies based on these animal models were reviewed in this paper.
