Early aggressive therapy for severe extensive ulcerative colitis

The current ulcerative colitis （UC） treatment algorithm involves a step-up therapeutic strategy, mainly aiming at inducing and maintaining its clinical remission. Although this therapeutic strategy may seem to be cost-efficient and reduce the risk of side effects, recent trials and case reports have shown that top-down therapy using infliximab induces a rapid clinical response, enhances patient quality of life, promotes mucosal healing, reduces surgeries and indirect cost of treatment for patients with severe UC. Moreover, since long-term treatment with infliximab is safe and well tolerated, early aggressive top-down therapeutic strategy may be a more effective approach, at least in a subgroup of severe extensive UC patients.

The clinical effects of DC-CIK cells combined with chemotherapy in the treatment of advanced NSCLC

Objective: The aim of the study was to evaluate the safety and therapeutic effects of autologous dendritic cells co-cultured with cytokine-induced killer cells (DC-CIK) combined with chemotherapy in advanced non-small cell lung cancer (NSCLC) patients. Methods: Fifty patients with advanced NSCLC (stages III to IV), who had received therapies in our Center (Department of Biotherapy, Affiliated to Cancer Hospital of Shanxi Medical University, Taiyuan, China) from August 2008 to January 2010, were treated by DC-CIK + chemotherapy as the combined treatment group; fifty advanced NSCLC patients treated with chemotherapy at the same time served as controls. The immunologic function, short-term therapeutic effects, the 1-year survival rate, the life quality, the chemotherapy side effects were compared between the two groups, the safety and therapeutic effects of DC-CIK cells therapy were observed too. Results: There was no obvious change of subsets of T cells in peripheral blood before and after therapy in DC-CIK + chemotherapy group, and IFN-γ was improved after therapy in this group (P < 0.05); in chemotherapy alone group, the ratios of CD3+CD4+, CD3+CD8+, CD3-CD56+ cells and the secretion of IL-2, TNF-α decreased significantly after therapy (P < 0.05); the ratios of CD3+CD8+, CD3+CD56+ were improved after cell culture (P < 0.05). The disease control rate (DCR) of DC-CIK + chemotherapy group was higher than that in the chemotherapy alone group (78.0% vs 56.0%, P < 0.05); the 1-year survival rates of DC-CIK + chemotherapy group and chemotherapy alone group were 50% and 44% respectively, had no significant difference. Compared with chemotherapy alone group, the occurrence of chemotherapy side effects (including bone marrow suppression, nausea and vomiting, peripheral nerve toxicity) was less in the DC-CIK + chemotherapy group (P < 0.05). The physical and appetite were better in DC-CIK + chemotherapy group after therapy. Conclusion: To compare with simple chemotherapy, DC-CIK + chemotherapy for advanced NSCLC is safe and effective, and it can improve patients' life quality and remission rate, and prolong their survival time.

Implications of Urban Growth on Domestic Water Consumption： A Case Study of Jorhat Town, India

This paper tries to embraces the urban growth in Jorhat town and its implications on water consumption at household＇s level. Urban growth is measured through the increase in the number of population and the aerial extent. It is a pathetic situation for Jorhat residents in case of domestic water consumption that due to rapid increase of population in the town, the existing water supply systems cannot cope with the current demand. So, the people of the town always struggle to collect water from other sources such as River Bhogdoi, ponds, dug well, water vendor etc., moreover, try to satisfy the limited daily household needs. The methodology adopted in this paper is involved on both primary and secondary data. The primary data has been collected through household survey pertains to 600 households from each of 19 municipal wards in Jorhat town in both pre and post monsoon seasons. To highlight the growth of population and population projection, the compound rate of growth method has been used and it is tried to link with the future water demand in Jorhat town,

A study of the relationship between professional values and ethical climate and nurses'professional quality of life in Iran

Objective:To explore the relationship between nursing professional values and ethical climate and nurses'professional quality of life.Methods:The present study is a descriptive,cross-sectional work in which 400 nurses from various wards of hospitals in the south-east of Iran were studied.Data were collected using a questionnaire consisting of four sections:demographics,Nurses'Professional Values Scale-Revised(NPVS-R),the Hospital Ethical Climate Survey(HECS),and the Professional Quality of Life Scale(ProQOL).Results:The total mean scores for professional values were 105.29±15.60.The total mean score for the ethical climate was 100.09±17.11.The mean scores for the indexes of compassion satisfaction,burnout,and secondary traumatic stress were 45.29±8.93,34.38±6.84,and 32.15±7.02 respectively.The relationships between professional values and the indexes of compassion satisfaction(r=0.56),burnout(r=0.26),and secondary traumatic stress(r=0.18)were found to be positive and significant(P<0.001).Also,the relationships between ethical climate and the items of compassion satisfaction(r=0.60,P<0.001),burnout(r=0.15,P=0.002)were found to be positive and significant.Conclusion:An understanding of nurses'perception of professional values and improving the ethical climate at work can help nursing administrators identify more effective strategies toward increasing compassion satisfaction and lessening bumout and work-related stress.

Effects of a symptom management intervention based on group sessions combined with a mobile health application for persons living with HIV in China:A randomized controlled trial

Objective:This study aims to evaluate the effects of a symptom management intervention(SMI)based on symptom management group sessions combined with a mobile health(mHealth)application(app)on the knowledge of symptom management,the certainty of symptom self-management,symptom severity,symptom distress,medication adherence,social support,and quality of life among persons living with HIV(PLWH)in China.Methods:A parallel randomized controlled trial with 61 PLWH was conducted in Shanghai,China.The participants in the control group(n¼30)downloaded the Symptom Management(SM)app according to their needs and preferences,and received routine follow-ups.The participants in the intervention group(n¼31)were guided to download and use the SM app,and received four tailored weekly group sessions at routine follow-ups.Each group session lasted for approximately 2 h and targeted one of the major modules of the SM app.All the outcomes were assessed at baseline and post-intervention.The study was registered with the Chinese Clinical Trial Registry(ChiCTR1900024821).Results:The symptom management knowledge and certainty of symptom self-management were significantly improved after the intervention(all P<0.01).Compared with the control group,the scores of symptoms reasons knowledge score improved 11.47 points(95%CI:3.41,19.53)and scores of symptoms self-management knowledge score improved 12.80 points(95%CI:4.55,21.05)in the intervention group after controlling for covariates.However,other outcomes did not show statistically significant differences between the intervention group and the control group(P>0.05).Conclusion:The SMI could improve PLWH’s symptom management knowledge and certainty of symptom self-management.Multi-center studies with larger sample sizes and longer follow-ups are needed to further understand the effects of SM app on ameliorating symptom severity and symptom distress.More innovative strategies are also needed to promote and maintain the sustainability of the SM app.

Continued application of Endostar combined with chemotherapy in advanced hemangioendothelioma of bone

By one case of hemangioendothelioma of bone accompanying pulmonary metastasis was treated with rh-endostatin injection (Endostar) combined with chemotherapy. The patient got partial response (PR) for 3 years after the application of Endostar maintenance therapy and Endostar combined with taxane-based chemotherapy. During the period of using Endostar as monotherapy, the patient got long-term disease control and good quality of life. There was no drug related adverse event during the therapy of Endostar. Suggested continued using of Endostar combined with chemotherapy could achieve an convinced therapeutic effect. Then using Endostar as maintenance treatment after patient got the optimal efficacy was feasible and profitable. This treatment strategy of long-term administration of Endostar was worthy of further observation, to explore the feasibility for long-term administration of combined with chemotherapy in the treatment of hemangioendothelioma of bone accompanying pulmonary metastasis.

Kinetics of Treated Domestic Sewage Disinfection through Catalytic Oxidation with H2O2

The inactivation of bacterial cells through catalyzed oxidation using hydrogen peroxide as the primary oxidant agent is dependent on a series of factors, such as the concentration of the catalyst, the rate of hydroxyl radical formation in the controlled decomposition of the oxidant agent, and the concentration and toxicity of hydrogen peroxide. The objective of this study was to develop a mathematical model able to predict the kinetics of the inactivation Escherichia coli and total coliforms cells present in treated domestic sewage through catalytic peroxidation. The catalyst used was iron oxide supported on mineral coal （called CP）, and the effects of the operational conditions, including hydrogen peroxide concentration and dosage of catalyst, were evaluated. The results showed that the disinfection kinetics of the treated domestic sewage is dependent on the concentrations of hydrogen peroxide and catalyst dosage. The kinetic model was shown to be able to predict the behavior of the inactivation kinetics of the bacterium Escherichia coli ATCC-25922 when different concentrations of hydrogen peroxide （75 and 100 mg·L^-1） were used, regardless of the catalyst dosage.
