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.

Objective:To investigate the combining therapy which not only have cured effect but also can uphold and improve the NPC patient′s immunity function after radiotherrapy and chemotherapy.Method:90 cases randomly divided into 3 groups ①Local group (local injected with IL-2 +radiotherapy+chemotherapy);②General group(ivdrip with IL-2+radiotherapy+chemotherapy);③convention group(radiotherapy+chemotherapy).Checked and observed the immunity function around the immunotherapy and after the radiotherapy and chemotherapy.Result:Cellular immunity of 3 groups are lower and humoral immunity are hypetuntion than normal person.After treated with IL-2 the cellular immunity improves but there′s no great change of the humoral immunity. The immune status of the immune groups have not obvious change than before radiotherapy,at the same time,the cellular immunity of the convention group cut down and the humoral immunity doesn′t change obviously.Conclusion:①It has some effect to uphold and improve the NPC patient′s immunity function to treat with small dosage of IL-2 before radiotherapy and chemotherapy,general treatment is better than local injection;②The three therapies have not great influence on the patient′s humoral immunity.

ObjectiveTo study the effect of music exposure in juvenile stage on anxiety-like behavior and fear extinction in adult rats.Methods4 broods of two-week-old healthy Sprague-Dawleyda rats were separated into two groups randomly.The music groups were exposed to music from 20:00 to 22:00 for 21 consecutive days.When the rats were 5 weeks old,they were caged by sex,with 8 male rats and 6 female rats in each group.When the rats were 8 weeks old,the two groups were assessed in the elevated-plus maze test,the open-field test,trained and assessed by the conditional fear training and fear extinction training.ResultsIn the elevated-plus maze test:Prior to the foot shock,the percent of time spent in the open arms in the music group (female(7.07 ± 1.14)％,male (5.12 ± 1.95 ) ％ ) exhibited no significant difference (P＞ 0.05 ) comparing with the rats in the control group (female (4.65 ± 0.86 ) ％,male ( 4.86 ± 1.95 ) ％ ).After the foot shock,the percent of time spent in the open arms in the music group ( female ( 8.63 ± 3.35 ) ％,male ( 7.79 ± 2.49 ) ％ ) increased comparing to the control group (female(1.48 ±0.11)％,male(4.29 ± 1.68)％) (P＜0.01). In the open-field test:prior to the foot shock,the percent of time spent in the center zone of the music group ( female (6.16 ± 2.17 ) ％,male (6.25 ±3.47) ％ ) exhibited no significant difference (P＞ 0.05) comparing with the rats in control group (female(5.27 ±1.95 )％,male (6.22 ± 3.13 )％ ).After the foot shock,the percent of time spent in the center zone in the music group (female(8.52 ± 1.93) ％,male (6.95 ± 2.46 ) ％ ) was larger than the control group ( female ( 3.47 ±0.93 ) ％,male (4.36 ± 2.22 ) ％ ) (P ＜ 0.05 ).The fear extinction training showed that the percent of freezing time exhibited no significant difference between the male and female rats of the music group and control group in the first block of the first extinction training day and the percentage of freezing time of female rats in music group was significantly lower than that of female rats in control group on the third extinction training day.The percentage of freezing time of male rats in the music group was significantly lower than that of male rats in control group on the second and third training day.ConclusionMusic exposure in juvenile stage decreases the anxiety level after foot shock,and promotes the long-term fear extinction,while has no effect on the level of fear memory.
