Objective To analyze the current status and clinical characteristics of urinary incontinence in 138 elderly female inpatients so as to provide thoughts and directions for management and intervention implemented by medical institutions for urinary incontinence people. Methods Cross-sectional investigation was used in this study. From August 2018 to November 2018, this study selected elderly female inpatients at a Class Ⅲ Grade A hospital in Beijing by cluster sampling. The primary screening was carried out with the International Consultation on Incontinence Questionnaire Urinary Incontinence Short Form (ICI-Q-SF) and urinary incontinence knowledge scale. This study analyzed the clinical characteristics and urinary incontinence knowledge in elderly female inpatients with urinary incontinence. Results Among 1105 elderly female inpatients ≥ 60 years old, there were 138 of them with urinary incontinence accounting for 12.5％. Among 138 elderly female inpatients with urinary incontinence, the ages were (74.37±8.49) ranged from 60 to 99; the score of urinary incontinence assessment was (7.09±4.59) from 1 to 21; patients with the mild or moderate level of urinary incontinence occupied 90.6％ (125/138);87.0％ (120/138) of patients were with basic diseases interacted with urinary incontinence. There was a statistical difference in the self-perception influence of the urinary incontinence on life among patients with different conditions (P < 0.05). There were statistical differences in the urinary incontinence knowledge among patients with different education levels (P< 0.01). Conclusions In China, it still faces severe problem of urinary incontinence in elderly female inpatients. Basis diseases of some patients interact with urinary incontinence. Urinary incontinence medical problems should be explored with the scientific, standardized and effective methods because of the bottleneck that public lack knowledge.

Method Seventy-one patients with lung adenocarcinoma, 93 patients with lung adenocarcinoma ,76 cases of chronic obstructive pulmonary disease (COPD),63 cases of healthy volunteers were enrolled. Frequencies of blood CD4+ CD29+ T cells and their intracellular necrosis factor alpha(TNF-α)and interleukin 1(IL-1)were compared. Compare TNF-α,IL-1,integrin beta 1 and vascular endothelial growth factor(VEGF)levels in the patients with transferred pulmonary adenocarcinoma or with non-transferred pulmonary adenocarcinoma and their changes with the treatment of radiotherapy. Results the patients with lung adenocarcinoma and non lung adenocarcinoma were significantly higher than that of COPD and health group,and patients with lung adenocarcinoma is significantly higher than patients with non lung adenocarcinoma (P<0.05);Integrin beta 1,VEGF and CD4+CD29+T cells,TNF-αand IL-1 level in patients with lung adeno-carcinoma metastasis were significantly higher than non-transferred group(P < 0.05);After radiotherapy,CD4+CD29+T cells,TNF-αand IL-1 in patients with lung adenocarcinoma were significantly lower than before(P<0.05);CD4+ CD29+ T cells,TNF alpha and IL-1 with integrin beta 1 and VEGF had significantly positive correlations. Conclusion CD4+CD29+T cells and cytokines increase significantly in the blood of patients with lung adenocarci-noma,and are related to the prognosis of metastasis and radiation therapy,which has important clinical significance.

Objective To know the current situation of core competency of midwives in Guangzhou, and analyze the influencing factors.Methods A cross sectional survey was conducted among 256 midwives from 13 hospitals in Guangzhou to investigate their core competency.Results The total average score of core competency of midwives was (4.09±0.49). The scores of intrapartum care and antenatal care were higher,while the scores of progestational care and public health care were lower. Multivariate regression analysis showed that the core competency of midwives was influenced by several aspects,and they were work experience,work experience in midwifery,age,title,job and marital status (β′=0.771, 0.549,0.409,0.390,0.250,0.137;P<0.05).Conclusions The overall level of midwifery competency of midwives in Guangzhou is good,but their professional scope and role function need to be deepen and expanded,so as to satisfy the growing health care demand from pregnant women and their families. Managers should develop individualized and specific training and management strategies to improve midwives′ competency based on the condition of hospitals.

Results A total of 2 123 pairs of patients with and without HAI were included in the survey.The average cost of hospitalization in HAI and non-HAI groups were ￥25 845.30 and ￥12 006.14 respectively,￥13 839.16 on average was increased due to HAI.The average economic loss in provincial and ministerial levels of hospitals were￥21 409.83.The average economic loss in different regional hospitals were ￥9 725.42-￥18 909.59,and north China ranked the first.Economic loss caused by bloodstream infection and lower respiratory tract infection were more than other sites,which were ￥23 190.09 and ￥18 194.50 respectively.Conclusion HAI resulted in considerable direct economic loss.Prevention and control of HAI,especially bloodstream infection and lower respiratory tract infection should be paid more attention.

Objective To evaluate the efficacy and toxicity of induction chemotherapy with nedaplatin and docetaxel plus concurrent intensity?modulated radiotherapy ( IMRT) with nedaplatin or cisplatin in the treatment of locally advanced nasopharyngeal carcinoma (NPC). Methods A total of 223 patients with pathologically diagnosed locally advanced NPC in five treatment centers from 2011 to 2012 were randomly divided into two groups. In the test group, one hundred and thirteen patients received two cycles of induction chemotherapy with docetaxel (65 mg/ m2 on day 1) and nedaplatin (80 mg/ m2 on day 1) plus concurrent IMRT with nedaplatin (40 mg/ m2 on day 1). In the control group, 110 patients received two cycles of induction chemotherapy with the same regimens plus concurrent IMRT with cisplatin (40 mg/ m2 on day 1). The survival rates were calculated with the Kaplan?Meier method and the differences in the survival rates between the two groups were analyzed using the log?rank test. Comparison of the incidence rates of adverse reactions between the two groups was made by the chi?square test. Results The follow?up rate was 99?? 1%.The response rates at 3 months after treatment in the two groups were both 100%. The 2?year local recurrence?free, regional recurrence?free, distant metastasis?free, and overall survival rates were 94?? 0%, 94?? 2%, 88?? 2%, and 90?? 3%, respectively, in the test group, versus 93?? 4%, 94?? 1%, 86?? 7%, and 87?? 3% in the control group ( P= 0?? 757、 0?? 478、 0?? 509、 0?? 413). The incidence rates and severity of leucopenia, neutropenia, and thrombocytopenia were significantly higher in the test group than in the control group ( P= 0?? 027 , 0?? 028 , 0?? 035 ) . The incidence rates and severity of hemoglobin reduction and nausea /vomiting were significantly lower in the test group than in the control group (P= 0?? 000,0?? 023). There were no significant differences in the incidence rates of mucositis and xerostomia between the two groups ( P=0?? 483,0?? 781). Conclusions The short?term efficacy of induction chemotherapy with nedaplatin and docetaxel plus concurrent IMRT with nedaplatin is similar to that with cisplatin in the treatment of locally advanced NPC. The mild gastrointestinal reactions can be tolerated by patients. However, the severe myelosuppression should be closely monitored during the treatment.

Background and objectiveLung cancer is the leading cause of cancer-related deaths worldwide, and metastasis is the major cause of death in lung cancer patients. MiR-373 is closely associated with invasion and metastasis in other tumor cells. hTis study explored the expression of miR-373-3p in non-small cell lung cancer (NSCLC) and its effect on the invasive and metastatic capabilities of lung adenocarcinoma cells, as well as their mechanisms of action.MethodshTe expression of miR-373-3p in NSCLC tissues and lung adenocarcinoma cell lines was detected by quantitative reverse transcrip-tion polymerase chain reaction. hTe roles of miR-373-3p in regulating lung adenocarcinoma cell invasion and metastatic prop-erties were analyzed with miR-373-3p mimic/inhibitor-transfected cells via Transwell chamber assay. Matrix metalloproteinase MMP-9 and MMP-14 protein levels were detected by Western blot in lung cancer cells atfer transfection.Results MiR-373-3p was upregulated in 51 NSCLC tissues and 5 NSCLC cell lines. Gain-of-function and loss-of-function studies showed that overexpression of miR-373-3p promoted H1299 cell migration and invasion, which resulted in upregulation of MMP-9 and MMP-14. By contrast, miR-373-3p knockdown inhibited these processes in A549 cells and downregulated the expression of MMP-9 and MMP-14.ConclusionOur results demonstrated that miR-373-3p participated in the invasion and metastasis of lung adenocarcinoma cells, partly by upregulation of MMP-9 and MMP-14.

Objective To study the effects of Lentinan on bleomycin A5’s inhibition effects in hemangioma-derived endothelial cell. Methods Hemangioma-derived endothelial cell line EOMA were divided into LTN group (only lentinan treatment), BLE group (only bleomycin A 5 treatment), L+B group (Lentinan and bleomycin A5 treatment) and CON group (no lentinan and bleomycin A5 treatment). Cell proliferation, cell cycle, PI and apoptosis were detected and compared among four groups. Results The differences of absorbance in LBE group was significantly higher than that in L+B group after treatment for d 1-d 7 (P<0.05), but both of them were significantly lower than in CON group and LTN group (P<0.05). The G 0/G 1 stage and apoptosis rate in L+B group was significantly higher than in BLE group(P<0.05), while it was significantly lower in S stage, G 2/M stage and PI(P<0.05). Conclusion Lentinan could significantly promote bleomycin A5’s inhibition effects on hemangioma-derived endothelial cell.

Objective To study the effects of 5-azacytidine’s demethylation for P16 gene on hemangioma cell’s proliferation and apoptosis.Methods Bisulfite sequencing PCR was applied to detect P16 gene′s promoter methylation status in 5-azacytidine treated and untreated EOMA cell line.RT-PCR and western blot were used to detect the P16 gene mRNA and protein expressions.Flow cytometry was used to detect cell proliferation, cell cycle and cell apoptosis.The differences of P16 gene′s promoter methylation status,mRNA and protein expressions,cell proliferation,cell cycle and apoptosis in two groups were compared. Results The methylation rates in 1st and 13th CGs were 0%after 5-azacytidine treatment in EOMA hemangioma cell line,which were lower than in untreated cells.The mRNA and protein expressions increased after 5-azacytidine treatment,which were significantly higher than in untreated cells.The absorbance,S phase and G2/M phase and PI after 5-azacytidine treatment were lower than untreated cells,while the G0/G1 phase and apoptosis rates were higher.Conclusion The P16 gene promoter is hypermethylated in hemangioma cells with silent gene expressions.5-azacytidine could reverse P16 gene′s promoter methylation and silent gene expressions,which inhibit hemangioma cell’s proliferation and promote apoptosis.

Objective To investigate the relationship between RKIP expression and the efficiency of radiotherapy in NPC patients and evaluate the possibility of using RKIP as a predictor of radiosensitivity.Methods A total of 180 patients with NPC in Sun Yat-sen University Cancer Center without evidence of distant metastasis at initial diagnosis were enrolled in this study,who had received intensity-modulated radiotherapy alone.Patients were classified into 2 groups according to criteria below:patients with biopsy proven recurrent diseases occurring at nasopharynx and/or neck within 5 years after radiotherapy were classified as the radioresistant group.The pathological type at relapse was the same as the previous one before treatment.Patients with a minimum follow-up of 5 years after radiotherapy without evidence of recurrence at the original site of the tumor were classified as the radiosensitive group.Patients in the 2 groups were matched according to the factors related with radiosensitivity.RKIP was examined by immunohistochemical staining before radiotherapy.The relationship between RKIP expression and the effect of radiotherapy were analyzed.Results The positive rate of the RKIP expression in the radiosensitive group versus the radioresistant group was 80.0％ versus 26.7％.The positive rate (x2 =12.498,P ＜0.01) and the intensity of the RKIP expression (x2 =51.429,P ＜ 0.01) were significantly different between 2 groups with a negative correlation with radio-resistance to NPC (r =-0.344,-0.535,respectively,P ＜ 0.01).Based on the RKIP expression,the radiosensitivity,specificity,accuracy,positive predictive value,negative predictive value,false positive and false negative were predicted as follows:80.0％,73.3％,77.2％,75.0％,78.6％,26.7％,and 20.0％,respectively.Conclusions RKIP protein shows negative correlation with radioresistance to NPC and could serve as a biomarker in preliminarily screening the intrinsic radiosensitivity of NPC.

Objective To evaluate the treatment efficacy,toxicities and prognostic factors of nasopharyngeal carcinoma ( NPC ) treated with intensity modulated radiation oncology ( IMRT ).Methods Between January 2006 and August 2008,300 patients with pathologically diagnosed NPC from 6 center received IMRT.The number of patients with stage Ⅰ,Ⅱ,Ⅲ and Ⅳa+b disease (UICC/AJCC 2002 staging system) were 6,45,141 and 108,respectively.The prescription doses were as follows:70-74 Gy/30f toplanning target volume of primary nasopharynx tumor ( PTVRλ),68-70 Gy/30f to planning target volume of positive lymphnode (ptvnd),60-64 Gy/30f to higher risk region (PTV1),50-54 Gy/30f to lower risk region (PTV2).Patients with stage Ⅲ and Ⅳa+b disease also received cisplatin-based chemotherapy.Cox method was used for Multivariate analysis.ResultsThe follow-up rate was 99.7％.The 4-year rate of local control,regional control,metastasis-free survival (DMFS),disease-free survival (DFS) and overall survival (OS) was 94.0％,95.5％,87.4％,80.8％,86.1％,respectively.Mucositis was the most severe acute toxicity,with 18.0％grade 1,48.7％grade 2,33.3％grade 3.No patient suffered from grade 4mucositis.Xerostomia was the most common late toxicity,with 12.0％ grade 0,75.7％ grade 1,12.3％grade 2.No grade 3-4 xerostomia was observed.There were 18,15 and 42 patients failed in local,regional and distant metastasis,respectively.Multivariate analysis showed that N stage was the only prognostic factor for OS (x2 =5.17,P=0.023),DMFS (x2 =6.91,P=0.009) and DFS (x2 =8.15,P=0.004) in these patients.ConclusionsIMRT can improve the treatment efficacy of NPC.The acute and late toxicities were tolerated.Distant metastasis becomes the main treatment failure.N stage is a significant prognostic factors.
