Objective To study the application effects of from-bottom-to-up objective management model in nursing quality control.Methods Eight surgical departments in our hospitals were selected as research objects.Traditional objective management model was applied in the control group (8 004 cases,9 453 visiting times) from June 2012 to June 2013.From-bottom-to-up objective management model was applied in the experimental group (8169 cases,9 603 visiting times) from July 2013 to July 2014.Nursing work quality and continuous improvement projects were compared between two groups by questionnaire survey,a return visit by telephone and statistical evaluation.Results The satisfaction of patients with nurses' service attitudes and professional technology level and the awareness of patients about major nurses in the experimental group were significantly higher than those in the control group [95.56％ (7 806/8 169),95.19％ (7 776/8 169),97.17％ (7 938/8 169) vs.93.22％ (7 461/8 004),92.62％ (7 413/8 004),84.60％ (6 771/8 004),allP＜0.01].Patient complaints and the incidence of nursing adverse events in the experimental group were significantly lower than those in the control group (46,16 cases vs.85,39 cases,x2=9.783,P＜0.01).Conclusions Applying from-bottom-to-up objective management model could cultivate self-control abilities and innovation awareness of nurses,which can improve nursing work quality.

Purpose:To study the molecular mechanism that d etermines the cell cycle differences between human giant-cell carcinoma cell st rains 95C and 95D. Methods:FACscan was used to analyze the cell cycle of 95C and 9 5D cells, and the proliferation ability of 95C and 95D cells was measured by MTT assay. We further detected the expression levels of cell cycle factors by Weste rn blotting. Results:Our data showed that the proliferation ability of 95D c ells is higher than that of 95C cells, and that the cell number in S phase of 95 D cells is much larger than that of 95C cells. We further found that the express ion level of p27 in 95D cell is lower than that of 95C cells. In addition, the e xpression levels of CDK2 and p-RB of 95D cells are higher than that of 95C cell s. Conclusions:Our results indicated that low expression level of p27 lead to the increased proliferation ability of 95D cells, which might reflec t the progression of human lung cancer cells in cell cycle facets.

Objective To evaluate the expression of G250 mRNA in patients with renal cell carcinoma (RCC) and its clinical significance. Methods A semi-quantitative reverse transcription (RT)-PCR was developed to assay the levels of G250 mRNA obtained from 7 normal renal tissues and 33 cases of RCC.Of the 33 RCC cases,28 had clear cell carcinoma and 5 had non-clear cell carcinoma.By UICC staging, 8 cases were diagnosed with T_1 stage carcinoma,13 with T_2 and 12 with T_3.Pathological grading showed 11 cases of G_1,15 of G_2,and 7 of G_3. Results Among the 33 cases of RCC,G250 mRNA expression was present in 28 cases (84.8%).However, it was absent in all the 7 normal renal tissues.There was a significant difference between the 2 groups (P0.05);while they were 0.48?0.32,0.23?0.16 and 0.11?0.11,respectively,in RCC cases of G_1,G_2 and G_3,which showed that the expression of G250 mRNA was inversely correlated with tumor grades(P

Objective To investigate the change of caspase-3 and F-actin in the apoptosis of prostate cancer androgen-independent cell line DU145 induced by all-trans retinoic acid (ATRA).

Professor JIA Chunsheng believes that "Dongyuan's acupuncture therapy" proposed by GAO Wu could not entirely reflect LI Dongyuan's academic thought of acupuncture and moxibustion. Hence, we collected all of the academic works of LI Dongyuan and extracted the texts relevant with acupuncture-moxibustion therapy, titled as Dongyuan's acupuncture-moxibustion therapy. This process contributed to the deeper study on Dongyuan's acupuncture and moxibustion academic thought. By the influence of Dongyuan's acupuncture-moxibustion academic thought, in association with his clinical experience for dozens of years, Professor JIA Chunsheng proposed that acupuncture and moxibustion should pay attention to the regulation and tonification of spleen and kidney. In clinical practice, Zhongwan (CV 12), bilateral Tianshu (ST 25), Qihai (CV 6) and Guanyuan (CV 4) are commonly selected to consolidate the root, cultivate the primary and treat the spleen and kidney simultaneously. The locations of the above selected points are distributed like a star. This "star-like point selection method" points to the importance of the spleen and kidney (the primary qi). For many diseases, especially the disorders of internal injury, the star-like acupuncture therapy is commonly used and the relevant acupoints are supplemented. The good clinical efficacy has been achieved.
