Objective To explore methods to develop a hospital quality of care index system of county level hospitals based on the homepage of inpatient medical records and examine the validity of this system. Methods By means of literature review, homepage data and panel discussion, along with theories and statistical methods, indexes were identified. The dimensions and indices of the index system were pinpointed. Confirmatory factor analysis and normalization methods were combined to calculate the weights and scores of such indices. Scores were adjusted by Charlson comorbidity index ( CCI) with multi-regression method. The hospitals were ranked by adjusted scores in each dimension. The validity was evaluated by comparing the application results to universally acknowledged standards, such as hospital level and economic level of the geographic areas. Results An index system with 6 dimensions and 25 indices was developed, and the application results proved valid to some extent. The adjustment of CCI also proved effective. The 6 dimensions were correlated yet their directions were not consistent. Conclusions The methods and data used to develop the system have demonstrated strong operability and availability. The application results can reflect medical care quality in different aspects making it applicable among homogeneous hospitals. It is meaningful to assess dimensions respectively.

Objective To explore the influence of the scores and weights of the regular grade on the evaluation of students' learning effect.Method To compare the impact of the regular grade before and after adjustment on the total mark,analyze the problems exposed during scoring and search for the solutions according to Medical Microbiology results of four grades including Grade 2010 to 2013.SPSS 13.0 software was used for statistical analysis and Pearson method was used for correlation analysis and theory achievement scores.Results The regular grade of four grades scored highly,with the average (95.00 ± 3.80),(96.00 ± 4.55),(95.00 ± 2.84) and (95.00 ±-2.82) respectively.What was more,it had randomness.The correlation coefficient between regular grade and total mark were 0.069,0.149,0.984 and 0.285 respectively.The regular grade of Grade 2010 was the same as Grade 2013 and the theoretical score of Grade 2013 was 4 points lower than Grade 2010(71 vs.75),however the total mark of Grade 2013 was 1 point higher than Grade 2010 (80 vs.79),which showed the more the regular grade weights,the greater it impacted on the total mark.Conclusion The appropriate score and weight of the regular grade is important to evaluate the students' learning effect objectively.

Objective:
To construct a mouse derived pcDNA3. 1 ⁃3 × Flag⁃c⁃NUP85 expression plasmid and observe its effect on expression of inflammation factors in LPS⁃induced RAW264. 7 cells , as well as on the proliferation and apoptosis of RAW264. 7 cells.
Methods:
The NUP85 gene was amplified by PCR to construct pcDNA3. 1 ⁃3 × Flag-c⁃NUP85 eukaryotic expression plasmid. The pcDNA3. 1 ⁃3 × Flag⁃c vector was divided with enzymes. The purified PCR product was ligated with the vector, and the ligated product was transformed into bacterial competent cells. After identification by enzyme digestion , sequencing and analysis were performed. Then , it was transfected into RAW264. 7 cells , and the blank plasmid without NUP85 gene was set as the control group. The effect on cell proliferation and apoptosis were detected by CCK⁃8 assay and flow cytometry , and the expression of inflammatory cytokines such as tumor necrosis factor⁃α (TNF⁃α ) and interleukin⁃6 (IL⁃6) in LPS⁃induced RAW264. 7 cells was detected by Western blot and ELISA.
Results:
Enzyme digestion identification and Western blot results showed that pcDNA3. 1 ⁃3 × Flag⁃c⁃NUP85 eukaryotic expression plasmid was successfully constructed and expressed. The results of CCK⁃8 assay showed that the cell survival rate of NUP85 overexpression group was significantly lower than that of control group after 24 h[(0. 55 ± 0. 03) vs (0. 67 ± 0. 05) , F = 30. 98 , P < 0. 05 ] . The results of flow cytometry showed that the cell apoptosis rate of NUP85 overexpression group was higher than that of control group[( 15. 78 ±1. 05)% vs ( 13. 40 ± 0. 47)% , F = 75. 38 , P < 0. 05] . The results of Western blot and ELISA showed that after transfection of pcDNA3. 1 ⁃3 × Flag⁃c⁃NUP85 , the expression of TNF⁃α and IL⁃6 in RAW264. 7 cells were higher than those in the control group ,with statistical significance (P < 0. 05) .
Conclusion
NUP85 can inhibit the proliferation and promote apoptosis in LPS⁃stimulated RAW264. 7 cells , and NUP85 can promote the expression of inflammatory cytokines IL⁃6 and TNF⁃α in LPS⁃stimulated RAW264. 7 cells.

Objective:
To study the effect of Musashi-2 ( MSI2 ) overexpression on the imbalance of proliferation and apoptosis of human ovarian granulosa cell line (KGN) induced by dihydrotestosterone (DHT) .
Methods:
The gene expression profiles of human ovarian granulosa cells ( GCs) in primary culture were statistically analyzed to screen the differentially expressed genes.pcDNA3. 1-MSI2 eukaryotic expression plasmid was constructed and transiently transfected into the KGN cells,and the overexpression effect of MSI2 was detected by Quantitative Real-time PCR (RT-qPCR) and Western blot.After overexpressing MSI2 in DHT induced KGN cells,MTT colorimetry and Edu staining were used to detect the proliferation of cells in each group,and flow cytometry ( FCM) was further used to detect the apoptosis of cells in each group.
Results:
The mRNA expression level of MSI2 gradually decreased during the primary culture of human ovarian GCs.And pcDNA3. 1-MSI2 was successfully constructed and transfected into KGN cells to improve the mRNA and protein expression levels of MSI2.Then MTT,EdU and FCM results showed that compared with the blank group,DHT induction could significantly reduce the proliferation rate and increase the apoptosis rate of KGN cells (P <0. 05) .However,after MSI2 overexpression,the proliferation rate of KGN cells increased and the apoptosis rate decreased (P <0. 05) ,which were close to the blank group.
Conclusion
Overexpression of MSI2 can effectively alleviate the imbalance of proliferation and apoptosis of KGN cells induced by DHT,indicating that MSI2 plays an important role in GCs growth and follicle development.
