Objective To evaluate method of CT simulation (CT sim) in the treatment planning setup of esophageal carcinoma. Methods From Dec.1999 to Jun.2002, 49 patients with pathologically proved esophageal carcinoma were analyzed. All patients underwent CT sim and treatment planning was configured with three symmetrical fields in the isocenter mode. A few comparisons have been made between CT sim and conventional simulation (Con sim) in the treatment planning setup. Results The difference in isocenter position were observed between CT sim and Con sim with 3～18 mm.When the esophageal lumen was taken as portal center, the 90% isodose curve in 42.8%(21/49) of patients were able to cover the whole lesion. When taking the tumor as the portal center, the whole lesion of all patients was totally covered by the 90% isodose curve. Conclusion The CT sim has an advantage in the delineation of lateral extension of esophageal tumor than the Con sim .Selection of irradiation portal should be done according to the size the silhouette of the tumor.

ObjectiveTo summarize the clinical features of adult patients with abdominal type Henoch Scholein Purpura(HSP) to improve the early diagnosis and therapeutic outcome of HSP.Methods The clinical features of 31 adult patients with abdominal type HSP from the Hematology department of Handan First Hospital between March 2007 to June 2010 were retrospectively reviewed and compared with that of 30 adult patients with non-abdominal type HSP.Results All the 31 patients had abdominal pain.Of those patients,48.4％ had periumbilical colicky pain, 38.7％ had whole abdominal pain and 12.9％ had lower abdominal pain.The other clinical manifestations included nausea/vomiting(19.4％),positive feces occult blood test(45.1％) .EGD and Colonoscopy of 13 patients showed mucosal congestion, red macda, erosion and ulceration mainly in the descending duodenum, distal ileum and rectosigmoid.There was no difference in age, gender, allergic history and predisposing infection between those with abdominal pain and without.The patients with abdominal pain had more cases of mixed-type HSP than those without and the difference was significant (P ＜ 0.01) .Conclusion Patients with abdominal-type of HSP are mainly young adults.So we must be more alert to abdominal-type of HSP when facing young patients with abdominal emergency.Abdominal-pain-manifesting HSP patients are mostly mixed-type cases.Gastrointestinal endoscopy is specific and might provide valuable clues for early diagnosis.

Objective To investigate the distribution and antibiotic resistance patterns of uropathogens in children with complicated urinary tract infection to guide the empirical antimicrobial treatment.Methods Retrospective analysis of isolated bacteria from 141 children hospitalized with complicated urinary tract infection was performed from January 2011 to January 2013.Results Gram-negative bacillus were the main pathogens [56.6％(81/143)],and Escherichia coli was the leading cause (41.3％,59/143).Gram-positive bacillus accounted for 38.5％ (55/143),including Enterococcus faecium (17.5％,25/143) and Enterococcus faecalis (14.7％,21/143).Fungi caused 4.9％ (7/143) of the infections.The resistance of Escherichia coli to amoxicillin was the highest [92.0％ (23/25)] and resistance to imipenem (4.3％,2/47),amikacin (6.8％,4/59) and nitrofurantoin (6.8％,4/59) was lower.It was observed resistance of Enterococcus faecium to linezolid,quinupristin,vancomycin and nitrofurantoin was significantly lower than other common antibiotics.The resistance of Enterococcus faecalis to quinupristin,tetracycline,erythromycin,rifampicin was significantly higher than other common antibiotics.Concluusions Escherichia coli,Enterococcus faecium and Enterococcus faecalis are the common uropathogens.These pathogens have a high antibiotic resistance to many common antibiotics.The selection of empirical treatment of children with complicated urinary tract infection should be adjusted by antimicrobial susceptibility test.

Objective To explore the contents and modes of community nursing training and improve community care quality.Methods The training course and assessment standard were worked out according to practical work in community health service centers,including basic nursing skills,community first aid skills,hospital infection control skills,preventive health care skills and community document management skills.Toally 58 nurses from 11 community health service centers were trained for 36 hours from January to June,2016 and tested before and after training to assess the effect of training.Result After training,the scores on all skills were significantly higher than those before training (all P＜0.01).Conclusion Regular and practical training and management are the guarantee for the improvement of the community care quality.

This article gives insights into a series of research on the purpose, significance, system, execution and as-sessment of Medical Humanities Curriculums, based on the problems of the existing medical education. The MedicalHumanities Curriculums are divided into three major groups: the fundamental, the comprehensive and the practical,detailedly reasoned by their contents and functions.[

Objective:To provide the solution based on electronic authentication service and electronic signature for doctor and nurse in order to guarantee the integrity and authenticity of electronic medical records system(EMRS) in building, writing and storage.Methods: To establish integrated electronic signature platform based on the installation and debugging for the digital signature sever device; and to improve some parts of the database, such as the digital certificate, certificate logging and the integration process of digital signature etc.Results: The integrated electronic signature of EMRS can guarantee the authenticity and reliability of identity when doctor logged system or finished the normal medical work; and it can reduce manual signature process and contribute to finish the automatic signature after doctor or nurse finished EMRS and nursing recorder sheet.Conclusion: The implementation of the electronic signature can ensure the reliability of electronic medical records, achieve the complete electronic file storage for patient medical records, and greatly save manpower and material resources.

AIM: To establish quality standard for Compound Shengui Capsules. METHODS: Glycyrrhiza uralensis Fisch.、Panax notoginseng(Burk.) F.H.Chen、Salvia miltiorrhiza Bge.and Ligusticum chuanxiong Hort.were identified by TLC.Ammonium glycyrrhizinate and tanshinoneⅡ_A were determined by HPLC.(RESULTS): (TLC) spots developed were fairly clear and the blank test showed no interference.The linear rangers were 0.5-4?g(r=0.999 8)for ammonium glycyrrhizinate;0.04-0.32?g(r=0.999 6) for tanshinoneⅡ_A.The average recoveries of them were 98.9%,97.8%,respectively.

Objective To study the expression of DNA methyltransferase 1 (DNMT1) in human cervical carcinoma tissue and cells, analyze the relationship between the expression level of DNMT1 and the clinicopathologic features of cervical carcinoma, and explore the role DNMT1 plays in tumorigenesis of cervical carcinoma. Methods The expression levels of DNMT1 protein in 3 cervical cancer cell lines, 89 samples of cervial cancer tissue, 20 samples of cervical intraepithelial neoplasia (CIN) and 20 samples of normal cervix were determined by immunohistochemistry method. The expression levels of DNMT1 mRNA in all the cell lines and 79 paraffin sections of cervix tissue were determined by RT-PCR. Results The DNMT1 protein was expressed in all the three cervix cancer cell lines. Positive expression was detected in 71.9% of cervix cancer samples, 35.0% of CIN samples and 10.0% of normal cervix samples, with significant differences among the three groups (P
