Objective To establish the topotecan(TPT)-resistant cell line of human oophoroma (SKOV3/TPT), and to investigate its biological features. Methods To simulate the condition in clinical chemotherapy, drug resistant SKOV3/TPT cell line of human oophoroma was established by challenging SKOV3 with a large dose of TPT (2160ng/ml). Drug sensitivity was assessed by MTT assay. Light microscopy, electronic microscopy, trypan blue staining rejection, and cell counting were employed to determine the biological features of the cell line. Flow cytometry (FCM) was used to study the cell cycle distribution, the accumulation of intracellular drug, and the expression of P glucoprotein (Pgp). Results SKOV3/TPT cells were established successfully, and the resistance index (RI) was 10.67. They showed an obvious cross-resistance to CPT-11, MX and VCR, but still sensitive to taxol, cis-platin, VP16, MTX and 5-Fluorouracil. Comparing with the parent cells, their morphology was unchanged, but multiplication time was prolonged. The apoptosis rate and the proportion of G2+M phase cells of resistant cells were significantly higher than that of their parent cells (P

Objective To explore the effects of ultraviolet on DNA damage in keratinocytes and to observe the protective role of resveratrol for the cells. Methods Comet assay was employed to evaluate the damage after radiation with different doses of UV rays (UVA, UVB and UVC) of 0, 10, 30, 50, 70 and 90 mJ/cm2, and the effects after pretreatment with various concentrations of resveratrol under irradiation with 30 mJ/cm2. Results UVA irradiation (0 ~ 90 mJ/cm2) had no significant effects on HaCaT cells. However, TailDNA%, TailLength, CometLength, TailMoment and OliveTailMoment showed both UVB and UVC induced DNA damage in a dose-de-pentent manner. UVC was more harmful than UVB at the same dose. Conclusions The DNA breakage induced by UVB and UVC is dose-dependent. As compared with UVB, UVC is more harmful to HaCaT cells. Resveratrol exerts a protective effect in HaCaT cells irradiated by UVB or UVC.

Autoimmune hepatitis (AIH) is the first liver disease which has proved responsive to gluc()orticoids,and the standard therapeutic method is hormone combined with azathioprine.Given that some patients fail to reach the standard of immunosuppressive therapy,and the long-term use of immunosuppressive therapy has many adverse effects,it is necessary to reasonably use anti-inflammatory and liver-protecting drugs to minimize the dose of immunosuppressants,control liver inflammation,reduce the damage of liver cells,and delay the progression of the disease.This paper reviews the advances in the application of anti-inflammatory and liver-protecting drugs in the treatment of AIH,in order to help clinicians make rational decisions.

Objective To investigate the trough and peak vancomycin plasma concentrations in steady-state following regular dosage and to improve dosing regimen based on pharmacokinetic modeling, providing reference for clinical practice in children.Methods we retrospectively analyzed pharmacokinetics of vancomycin in 50 cases admitted in our PICU who had been confirmed or suspected with gram-positive bacterial infections following regular dosage[40 mg /(kg?d)].Then we tried to optimize dosing regimens with Monte Carlo simulation to evaluate different dosing regimens of vancomycin in children.Results with regular dosage of vancomycin,mean trough concentrations of vancomycin were (1 1.02 ±4.44 )mg /L, trough concentrations higher than 15 mg /L accounted for only 12%.In the actual program,the extension of a single intravenous infusion to 3 hours after administration would result in 26% of trough concentrations dis-tributing in the range above 15 mg /L.If we increased daily dose to 50 mg /kg and 60 mg /kg with simulation, the trough concentration distribution frequency above 15 mg /L would increase from 12% to 32% and 40%. If minimum inhibitory concentration of vancomycin to pathogenic bacteria (Staphylococcus aureus )was 1 mg/L,the probabilities of target attainment for pharmacokinetic/pharmacodynamic evaluation were 51.73%, 76.54% and 87.5% for three dosages [40 mg/(kg?d),50 mg/(kg?d)and 60 mg/(kg?d)]of vancomycin, respectively.we suspected that dosage of 60 mg/(kg?d)was a good choice.with this dosage regimen,we could achieve a substantial increase in the probability of target attainment.Conclusion Following regular dosages, trough concentration distribution frequency from 15 to 20 mg /kg is low.The extension of a single intravenous infusion time can not achieve a good result.According to the result of pathogenic bacteria and anti-microbial susceptibility tests,increasing daily dosage of vancomycin to 60 mg /(kg?d)will help to improve the trough concentration and get more clinic achievements.

Objective To investigate whether serum level of low-density lipoprotein cholesterol can predict the expan?sion of hemorrhage growth in elderly male patients with acute hypertensive intracerebral hemorrhage. Methods Patients (n=108) who visited our hospital with from June 2012 until May 2014 spontaneous hypertensive intracerebral hemorrhage with?in 6 hours of onset which is confirmed by initial computed tomography (CT) were sent to repeated CT within 24 hours of on?set. All selected patients were divided into the LDL-C≥2.49 mmol/L group and LDL-C<2.49 mmol/L group. Clinical data of these 2 groups were compared and the relationships of hematoma growth and its risk factors were analyzed. Results Baseline blood pressure, the level of blood glucose, PT, APTT, FIB, PLT and hemorrhage volume did not differ significantly between the LDL-C≥2.49 mmol/L group and LDL-C<2.49 mmol/L group. The ratio of hemorrhage growth in LDL-C<2.49 mmol/L group was significantly higher than that in LDL-C≥2.49 mmol/L group (34.21%vs 11.43%). Multiple logistic regres?sion analysis showed that LDL-C<2.49 mmol/L was the only risk factor contribute to hemorrhage growth. Conclusion Pa?tients with LDL-C<2.49 mmol/L in acute intracerebral hemorrhage are of high risk of hemorrhage growth so early attention and appropriate procedure are needed to prevent or slow its growth.

Objective:To explore the structure of maternal verbal scaffolding features and develop a questionnaire on Mother's language scaffolding characteristics, so as to provide a quantitative, convenient and economical self-assessment tool for describing maternal verbal scaffolding features.Methods:On the basis of qualitative research and literature research, a questionnaire survey was conducted among 704 mothers of preschool children. After item analysis and exploratory factor analysis, a formal questionnaire was formed. Two weeks later, 106 mothers were retested to collect test-retest reliability data. Preschool children's expressive vocabulary checklist was used as external criterion.Data were analyzed by SPSS 18.0 and Amos 21.0.Results:(1)The formal questionnaire includes 28 items with two factors-detailed support factor and control rejection factor, the internal consistency coefficients of the two factors were 0.849 and 0.811, the project load was from 0 .482 to 0 .701, and the variance contribution rate was 40.36%.(2) AMOS 21.0 was used for confirmatory factor analysis, indicating that the two-factor structure met the requirements of psychometrics.( χ 2/ df=1.96, RMSEA=0.05, NFI=0.86, CFI=0.90, IFI=0.89). (3)The results of two-factor text-retest reliability were 0.840 and 0.871 as well as the results of split-half reliability was 0.801.The internal consistency reliability was 0.740.The external validity analysis showed that the mother's education level was positively correlated with factor Ⅰ( r=0.288, P=0.000), but not with factor Ⅱ( r=-0.091, P=0.052). There was significant difference in factorⅠbetween mothers with expressive vocabulary development delay children (52.22±10.56) and non delayed children (57.71±7.51) ( t=-5.07, P=0.000). There also was a significant difference in factor Ⅱ between mothers with expressive vocabulary development delay children (37.12±10.09) and non delayed children (31.53±8.59) ( t=4.61, P=0.000). (4)There was no significant difference in the characteristics of language scaffolding between boys(factorⅠ(58.08±8.14), factorⅡ(32.86±9.51)) and girls' mothers(factorⅠ(56.93±8.20), factorⅡ(31.42±8.48)). Analysis of the sample groups showed that age did not affect the verbal scaffolding features of preschool children's mothers( F1=1.633, P1=0.181; F2=0.758, P2=0.518). Conclusion:There are two factors in the questionnaire of the verbal scaffolding features questionnaire, which meet the criteria of psychometrics.The questionnaire of the verbal scaffolding features questionnaire is suitable for evaluating the characteristics of language scaffolding of mothers of preschool children aged 3-6.
