Objective We observed the effect of topical application of mucopolyccharide polysulfate cream (hirudoid) on phlebitis prevention initiated by continuous infusion of 5-Fu with Baxter infusor. Methods 60 untreated patients with nasopharyngeal carcinoma were selected and randomly divided into the control group (28 patients) and the experimental group (32 patients). The patients of the experimental group were gently massaged with hirudoid along the infusion vein since the beginning of 5-Fu infusion, while the control group received no intervention. The incidence of phlebitis was observed in the two groups. Results The incidence of phlebitis in the experimental group was lower and the degree was lighter compared with the control group. Conclusions Hirudoid can decrease the incidence and released the symptoms of phlebitis initiated by continuous infusion of 5-Fu with Baxter infusor, and is effective to prevent and treat phlebitis.

Objective To explore the nursing method for the prevention and treatment of vaginal adhesions in patients treated with full-dose radiotherapy for cervical cancer. Methods From 2015 to 2016, 80 cervical cancer patients who received radiotherapy were treated with domestic vaginal washing, vaginal local use of"Fufangbao", infection control, diet and sexual rehabilitation guidance, and so on, and the nursing outcome was evaluated. Results Of the 80 patients, 6 were lost during follow-up, resulting in a follow-up rate of 925%. Ten, five, and three patients were found to have grade 1, 2, and 3 vaginal toxicity, respectively. The patients with grade 1 vaginal toxicity were not treated with special treatment and were asked to do more vaginal washing. The patients with grade 2 and 3 vaginal toxicity were treated with daily vaginal washing and"Fufangbao" for repairing the vagina;vaginal adhesions disappeared or improved 3 months later. The patients with no vaginal adhesions had regular sexual intercourse and thus had improved quality of life. Conclusions Effective clinical nursing can reduce the incidence of vaginal adhesions and stenosis, improve patients' quality of life, and promote the harmony of family.

Objective To develop a MOSAIQ Integration PlatformCHN (MIP) based on the workflow of radiotherapy (RT) and to meet the actual requirements in China and the special needs for the radiotherapy department.Methods MIP used C/S (client-server) structure mode running on the local network in the hospital and its database was based on the Treatment Planning System (TPS) and MOSAIQ database.Five network servers,as the core hardware,supplied data storage and network service based on cloud services.The core software was developed based on Microsoft Visual Studio Platform using C# network programming language.The MIP server could simultaneously offer network service for about 200 workstations,including entry,query,statistics,and print of data.Results MIP had 15 core function modules,such as Notice,Appointment,Billing,Document Management (application/execution),and System Management,which almost covered the whole workflow of radiotherapy.Up to June 2016,the recorded data in the MIP were as follows:13546 patients,13533 plan application forms,15475 RT records,14656 RT summaries,567048 billing records,and 506612 workload records.Conclusions The MIP based on the RT workflow has been successfully developed and used in clinical practice.It is an important part of radiotherapy information system construction with the advantages of intuitive operation,real-time performance,data security,and stable operation.It is digital,paperless,user-friendly,and convenient for the retrieval and statistics of data as well as information sharing and department management,and can significantly improve the efficiency of the department.More functions can be added or modified to enhance its potentials in research and clinical practice.
