Objective To quantify the incidental irradiation dose (ⅡD) to lymph node stations of esophagus when treating patients with T1-4N0 M0 thoracic esophageal squamous cell carcinoma (ESCC) with a dose of 60 Gy/30f.Methods Twenty-nine patients with medically inoperable T1-4N0M0 thoracic ESCC were treated with three-dimensional radiotherapy on involved-field.The conformal CTV was re-created using a 3 cm margin in the proximal and distal direction (following the course of the esophagus) beyond the barium esophagogram,endoscopic examination and CT defined GTV and a 0.5 cm margin in the lateral and anteroposterior directions of the CT defined GTV.The PTV encompassed 1 cm proximal and distal margins,0.5 cm radiaI margin on the basis of CTV.Cervical,mediastinal and abdominal lymph nodes were delineated respectively.Equivalent uniform dose (EUD) and other dosimetric paraneters were calculated for each nodal station.Nodal region whose metastasis rate is greater than 5％ was considered a high risk lymph node subgroups.Results Under a 60 Gy dose prescription,the median Dmean and EUD,V40 and V50 were ≥40 Gy,≥85％ and ≥75％ in most of the high risk nodal regions.For the subgroups whose EUD were less than 40 Gy,most of the ⅡD of these regions was significantly associated with the length and location of esophageal tumor (r =0.892,P =0.000).Conclusions Lymph node stations nearby of ESCC received considerable ⅡD with involved-field irradiation which could control subclinical lesions.But more clinical studies should be needed.

Objective:To analyze the cause of the blood heat syndrome in psoriasis.Methods: Made the investigation form about information of psoriatic patients through DME method and reference both Chinese and foreign documents,analyzed main component of data by SAS software.Results: The first main component of blood heat syndrome in psoriasis are infection,drinking,dietetic problem,and emotion;the second main component is family history;the third main component is dampness;the forth main component is the allergy to the food;the fifth is outside irritation.Through the corresponding investigation we found that food include hot food,beef,sheep and sea food,emotion problem include over work and stress,dampness include work and living in humid place for long time,outside stimulus meant chemical stimulus.Conclusion: The main cause of the blood heat syndrome in psoriasis are infection,drinking,dietetic problem,and emotion,family history,humidity,allergy to the food and chemical stimulus in order.

Objective To describe the consistency of three diagnostic criteria for metabolic syndrome(MS) proposed by ATP lI[ in 2005,CDS in 2004 and IDF in 2005 in Chinese.Methods With cluster sampling method,5 494 subjects was selected and studied, and the prevalence of MS was calculated according to three definitions with software SPSS 13.0.Results The crude prevalence of MS in Tongzhou area was 15.8% by IDF(2005) definition,8.5% by CDS(2004) definition and 15.8% by NCEP-ATPⅢ definition,women had higher prevalence than men(P

Two-dimensional electrophoresis(2-DE) is an important technique in proteomics research.The 2-DE system for proteome of Monascus ruber was established by comparing and analyzing the infection caused by different kinds of mediums,lysis buffer and the condition of rehydration.By cultivating the Monascus ruber with YES for 6 days,extracting total protein by TCA-acetone,lysis buffer with 8 mol/L urea,2 mol/L thiourea,4 % CHAPS,1 % DTT and 2 % Bio-lyte,an ideal 2-DE map with higher resolution and better legibility was obtained,which laid a foundation for the further studies on proteome of Monascus ruber.

Objective To explore connotative quality of how to improve the electronic medical records. Methods Combining with the ways of improving connotative quality in fact, the advantages and common defects of electronic medical records were reviewed and some suggests were brought forward. Results The connotative quality of electronic medical records could be enhanced by specific quality standards, the implementation of quality control of section links and the emphasis quality control suited to expert's specialty, at the same time, the connotative quality of electronic medical records was raised by monitor methods of informationazition platform. Conclusion Improving the whole medical level of hospitals is the crux of raising the connotative quality of medical records.

Objective To study local people's habits and customs concerning the prevention of dental fluorosis in an indoor coal-combustion-type fluorosis area of Zhaotong city Yunnan province, and to provide reference value for monitoring and control of the disease. Methods In 2008, 600 people of a 12-year-old group (400 people) and a 35 - 44-year-old group(200 people) were examined for dental fluorosis and oral health status in an indoor coal-combustion-type fluorosis area of Zhaotong. A questionnaire survey of 120 students and 60 adults was carried out on their habits and customs, stove changing status, knowledge of prevention of dental fluorosis, social psychology status, oral health behavior and their need for medical treatment. Results The total prevalence of dental fluorosis was 91.0% (546/600), dental fluorosis index was 2.58. The total prevalence of dental fluorosis of 12-year-old group was 86.5%(346/400), and dental fluorosis index was 2.12. The total prevalence of dental fluorosis of rural student was 90.5% (181/200), which was obviously higher in the rural group than the urban group [82.5% (165/200), χ2 = 5.48, P < 0.05]. The total prevalence of dental fluorosis of 35-44-year-old group was 100% (200/200), which was obviously higher than that of the 12-year-old group(χ2 = 29.67, P < 0.01). The rates of using coal, baking of food, changing stoves were 66.7% (60/90), 14.4% (13/90),57.8% (52/90), respectively, and these values of the urban were much lower than those of the rural[95.6%(86/90) ,31.1%(28/90) ,76.7%(69/90),χ2 = 24.51,7.11,7.29, all P < 0.01]. Only 23.3% (42/180) of people surveied had the knowledge of prevention of dental fluorosis, and the rate in the adult group[56.7% (34/60)]was higher than that of the student group [6.7% (8/120), χ2 = 55.9, P < 0.01]. The same rate in the urban student group was 0(0/60), and the rural student group was 13.3%(8/60), there was a significant difference between them(χ2 = 5.66, P < 0.05). Seventy-three point nine per cent( 133/180) of these people thought dental fluorosis had significant effect on their life, 91.1%(164/180) of these 'people wished to be treated. Eighty-four point four per cent( 152/180) of the people had a habit of toothbrushing,and 50.7% (77/152) of these people were still using toothpaste containing fluorine. Conclusions Zhaotong is a serious indoor coal-combustion-type fluorosis area. Enhancing health education to local people especially to students, and changing people's unhealthy habits and customs are keies to control the prevalence of indoor coal-combustion-type dental fluorosis.

Objective To study the effects of Guhong injection on the expression of vascular endothelial growth factor (VEGF) in the cortex 14 days after cerebral ischemia-reperfusion. Methods 30 male Sprague-Dawley rats were divided into sham group (n=6), ischemia group (n=6), aceglutamide injection group (n=6), Honghua injection group (n=6) and Guhong injection group (n=6). The middle cerebral arteries of all the rats were occluded for 2 hours and reperfusion, except the sham group. Drugs were administered once a day 24 hours after reperfusion. The expression of VEGF in cortex was detected with enzyme-linked immunosorbent assay (ELISA) 14 days after reperfusion. Results The expression of VEGF decreased in the ischemia group compared with the sham group (P<0.001), and it increased both in the aceglutamide and Guhong injection groups compared with the ischemia group (P<0.05). Conclusion Guhong injection can significantly increase the expression of VEGF in the cortex 14 days after ischemia-reperfusion, which may be one of the ways for neuro-protection.
