Chinese Journal of Pharmacoepidemiology 2006;0(04):-
Objective:To evaluate the effects and safety of adjuvant chemotherapy for adults with malignant glioma. Method:PubMed,EMBASE,Cochrane Library,CNKI,Chinese Biomedical Database and VIP were reviewed and randomized controlled trials of adjuvant chemotherapy for adults with malignant glioma were identified.The quality of the included trials was evaluated by two reviewers.A meta-analysis was conducted in homogeneous studies.Result:13 controlled trials were involved in 3639 patients.The meta-analysis results showed that compared with radiotherapy alone,the adjuvant chemotherapy might increase 1 year survival,2 years survival,2 years progression free survival,and their OR and 95%CI were 0.61(0.43,0.87),0.52(0.33,0.81),and 0.42(0.19,0.90),respectively,but 1 year progression free survival and 5 years survival had no statistical significance.Their OR and 95%CI were 0.52(0.26,1.04) and 0.75(0.54, 1.04) respectively.5 studies(2418 cases) reported that the toxicity rates increased in patients who received radiotherapy plus adjuvant chemotherapy compared with those in patients who received radiotherapy alone.Conclusion:The adjuvant chemotherapy may increase one year survival and two years survival,and have advandage impact on 2 years and 5 years progression free survival.Owing to the high possibility of attrition bias and measurement bias in the included studies,there must be a negative impact on evidence intensity of our results and therefore,some randomized controlled trials with high quality have to be expected to obtain the best evidence.
2.Surgical treatment of thyroid microcarcinoma
Journal of International Oncology 2015;(5):374-376
For thyroid microcarcinoma(TMC),the incidence is not obvious,the lesion is small,the symptoms are not distinctive and the progression is slow. Studies suggest that patients with the age over 45 years or below 15 years old,male,lesion over 5 mm and lymph node metastasis have poor prognosis and active opera-tion treatment is needed. When in operation,the excision extension should take clinical data into consideration, and complete resection of the lesions and preservation of the normal tissue as much as possible should be done. For the patients with lymph node metastasis,lymph node dissection is feasible,and the central lymph node dis-section is applicable for the negative lymph nodes. Reduce the risk of recurrence and metastasis,increase the survival rate of patients with tumor and improve the quality of life,become the prime target of the follow up,in which the standardized treatment of TMC plays a vital role.

Objective To investigate the level and influencing factors of subjective well-being of nurses and establish a model of the relationship of job stress, self-efficacy and subjective well-being. Methods Totally 438 nurses from 5 hospitals in Changchun city were investigated with the self-designed demographic questionnaire, General Well-Being Scale, Nurse Job Stressors Scale and Self-Efficacy Scale. Results The total score of subjective well-being was (71.36 ± 18.83) points. Single factor analysis found that age (F=1.759, P<0.01), department (F=1.712, P<0.01), professional title (F=1.364, P<0.05), years of working (F=1.420, P<0.05) and monthly income (F=1.632, P<0.01) were statistically significant. Multiple linear regression analysis showed that sex (t=-2.447, P<0.05), the first factor of job stress (t=-5.033, P<0.01), the second factor (t=-2.478, P<0.05), the third factor (t=-2.315, P<0.05), the fifth factor (t=-5.862, P<0.01) and self-efficacy (t=10.705, P<0.01) were the predictive effectton of subjective well-being. The result of path analysis shows that self-efficacy has a significant effect of adjustment on job stress and subjective well-being (direct effects=-0.62, indirect effects=-0.24, P<0.01). Conclusions The nurse subjective well-being is in the medium level. Hospitals and all related departments should take effective measures to reduce or eliminate unfavorable factors and increase the protective factors, and then improve the level of nurses′subjective well-being and nursing quality.

Hepatitis C virus (HCV), one of the major pathogens of viral hepatitis, causes significant hazards in humans. Interferon treatment in combination with ribavirin is used as the first line clinical treatment for HCV infection. However, good response to this treatment has only been observed in few patients and repeated recurrence has also been reported frequently. Therefore, new antiviral agents and therapies are in urgent demand. Here, we report a newly constructed Escherichia coli RNase P based M1GS ribozyme that can specifically and efficiently target the core gene of HCV. The guide sequence (GS) of this M1IGS was designed according to the sequence of the core coding region of HCV genome. The GS was then covalently linked to the 3' terminus of M1 RNA, the catalytic subunit of RNase P from Escherichia coli. The specification of this sequence-specific ribozyme, M1GS, was then examined using an in vitro cleavage assay. The cytotoxicity and its activity in inhibition of HCV gene expression and viral proliferation were further studied in vivo. Our results show that the reconstructed M1GS ribozyme displayed obvious catalytic activity in cleaving target mRNAs fragment in vitro. Notable reduction in the expression of HCV core protein and a 1 000-fold reduction in viral growth were also observed in cultured HCV infected Huh7.5.1 cells expressing the functional M1GS ribozyme. This study demonstrated a direct evidence for the antiviral activity of the customized M1GS-HCV/C141 ribozyme, and thus provided a promising new strategy for clinical treatment of HCV infection.

Objective To observe the effect of ulinastatin on the expression of interleukin 15 (IL-15), connective tissue growth factor (CTGF) and malondialdehyde (MDA) in rat peritoneal mesothelial cells (RPMCs) induced by high glucose. Methods RPMCs were isolated, cultured and passaged by trypsin, then identified. The third generation of cultured RPMCs were used in the experiment. RPMCs were divided into normal control group, high glucose (1.5%, 2.5%, 4.25%) for 6 hours and 12 hours, high glucose (2.5%) for 3, 6, 12, 24 hours or ulinastatin (160, 320, 640U/ml) for 12 hours. IL-15 mRNA was detected by real-time PCR. IL-15 and CTGF protein in supernatants was detected by ELISA. MDA protein was detected by TBAS. Results Compared with the control group, the expression of IL-15, CTGF and MDA was significantly increased in the groups stimulated by high glucose (P<0.05) in dose- and time-dependent manner. Ulinastatin could significantly decrease the expression of IL-15, CTGF and MDA induced by high glucose in dosedependent manner both in protein and gene levels (P<0.05). Conclusions High glucose can up-regulate the expression of IL-15, CTGF and MDA in RPMCs. Ulinastatin can reverse these changes.
