Objective To evaluate the factors affecting the treatment of old persons diagnosed hypertension. Method A sample of 55566 persons from the community of Yanji area of Shanghai was recruited. Results Among the 19295 persons over sixty there are 5842 patients with hypertension, the morbidity was 30.3%. Among the 36271 persons aged fifteen to fifty-nine there are 3536 patients with hypertension, the morbidity is 9.7%. The ratio of non-treatment in the old age group is 3.1% and in younger group is 8.8%. However,the compliance to the treatment was better in the younger than in old group(73.7% vs 56.2%). The age,hypertension grade and sex were all accounted for the differences in the regularity of the hypertension treatment. Conclusion Further effort on the education of non-old hypertensive patients is essential to decrease the damage from hypertension.

Objective To investigate the effect of di-( 2-ethylhexyl ) phthalate (DEHP) on pregnant rat and the protection of zinc.Methods Fifty rats were randomized equally into 5 groups consisting of blank (given 1 ml 0.9％ sodium chloride),corn oil (given 1 ml corn oil),zinc (given 1 ml zinc gluconate including 1.2 mg zinc),DEHP (given 50 mg · kg-1 · d-1 DEHP)and DEHP + zinc (given 50 mg· kg-1 · d-1 DEHP + zinc gluconate ).At the beginning of the experiment (about 7 d before pregnancy),the female rats were administered with corresponding drugs everyday.The pregnant rats were killed and the fetal rats were removed on 19th day.The following results in each group were recorded:the body weight and the organic weight of the female rats,the number and the weight of fetus rats and the placental weight.Results The weight and the coefficient of female rats' kidney/body,spleen/body,brain/ body,and heart/body in DEHP group compared with other groups were not statistical significance (all P ＞0.05).The coefficient of female rats' liver/body,uterus/body,and ovary/body of blank group were (4.4 ± 0.7 ) ％,( 1.26 ± 0.09 ) ％,( 0.083 ± 0.009 ) ％ respectively,corn oil group were (4.5 ± 0.6 ) ％,( 1.29 ±0.10)％,(0.084 ±0.008)％,zinc group were (4.4 ±0.4)％,( 1.26 ±0.08)％,(0.084 ± 0.009 ) ％,DEHP group were ( 5.4 ± 1.0 ) ％,( 1.11 ± 0.08 ) ％,( 0.074 ± 0.012 ) ％,and DEHP + zinc group were (4.4 ± 1.0)％,( 1.28 ± 0.10)％,(0.082 ± 0.007)％ ; in DEHP group the coefficient of female rats' liver/body,uterus/body,and ovary/body compared with other groups was statistical significance ( P ＜ 0.05 ).The fetal quantity,fetal weight and placental weight of female rats of blank group were 12.8 ± 2.7,(6.03 ±0.16) g,( 1.00 ±0.03) g respectively,corn oil group were 13.6 ±3.1,(6.07 ±0.20) g,(1.00±0.04) g,zinc group were 13.3 ±3.1,(6.16 ±0.18) g,( 1.00 ±0.05) g,DEHP group were 9.2±4.1,(4.03 ±0.09) g,(0.95 ±0.03) g,and zinc +DEHP group were 12.1 ±2.9,(6.09 ± 0.17 ) g,(0.99 ±0.03 ) g.In DEHP group the fetal quantity,fetal weight and placental weight of female rats compared with other groups were statistical significance ( P ＜ 0.05 ).Conclusion DEHP can damage female rats and fetal rats in gestation period.Zinc supplied before pregnancy can relieve the influence by DEHP.

Objective Based on active monitoring MRSA carriage for hospitalized patients, the relationship between colonization pressure and MRSA cross transmission in wards without rigorous contactisolation measures was analyzed, and the role of colonization pressure in predicting MRSA cross transmission was further evaluated. Methods From March to December 2009, active MRSA colonization screening was performed for 240 hospitalized patients in emergency ward and 94 cases in RICU in our hospital. rep-PCR method was employed to do homology analysis on MRSA strains obtained in this study. MRSA weekly colonization pressure, threshold colonization pressure ,cross transmission rate were calculated respectively. RR of MRSA cross transmission under higher level of colonization pressure and lower level of colonization pressure was analyzed. Results MRSA carriage rates on admission for patients in emergency wards and RICU were 6. 25% (15/2A0) and 13. 83 % (13/94) ,and MRSA cross transmission occurred in 13 weeks and 14 weeks in above two units, respectively. Threshold colonization pressures for above two units were 6. 49%and 17. 66%, respectively. For emergency ward, the MRSA cross transmission rate under higher level of colonization pressure was significantly higher than that under lower level of colonization pressure (x2 = 7. 10,P＜0. 01), the RR of MRSA transmission was 9. 61 (95% CI:1. 25-74.00). For RICU, the MRSA cross transmission rate under higher level of colonization pressure was significantly higher than that under lower level of colonization pressure(x2 = 12. 60, P＜0. 01 ), the RR of MRSA transmission was 15.87 (95% CI:2. 06-122. 10). Conclusions Higher level of colonization pressure is an important risk factor for MRSA transmission, and average colonization pressure can be used as a prediction index for MRSA transmission and strengthening prevention and control measures.

The metabolic effect of Fo-Shou-San on blood deficiency mice was studied by using metabolomic method. UPLC-QTOF/MS was used to analyze the plasma metabolome in blood deficiency mice. MS data were processed by MarkerLynx software. With multivariate statistical analysis of plasma metabolite profiles, a clear separation among control, blood deficiency model, and Fo-Shou-San groups was achieved. Potential biomarkers were selected according to the parameters of variable importance in the projection (VIP) and identified according to MS information and database retrieval. The metabolic network of blood deficiency was predicted via MetPA database. Twenty-two potential biomarkers were identified and used to explain the thiamine metabolism, arachidonic acid metabolism, sphingolipid metabolism, glyoxylate and dicarboxylate metabolism, histidine metabolism, nicotinate and nicotinamide metabolism, cysteine and methionine metabolism, tryptophan metabolism, starch and sucrose metabolism, tyrosine metabolism and citrate cycle (TCA cycle). Those metabolic pathways were disturbed in blood deficiency mice, but which could be regulated nearly to normal state after Fo-Shou-San administration. In this study, the metabolomics of blood deficiency mice and the action mechanism of nourishing blood effect of Fo-Shou-San were evaluated. The physiological and metabolic state of the organism could be represented comprehensively by using metabolomics. And metabolomics can be used to evaluate the pharmacodynamics and related mechanisms of Chinese medicine and formulae.

Objective To compare the position,volume and matching index (MI) of patientspecific internal gross tumor volume (IGTV)delineated by 4 different approaches based on three- dimensional and four - dimensional CT ( 3 DCT and 4 DCT ) image for primary esophageal cancers.Methods Thirteen patients with primary esophageal cancer underwent 3DCT and 4DCT simulation scans during free breathing,and the patient were divided into group A (tumor located in the proximal thoracic esophagus) and B (tumor located in the mid-and distal thoracic esophagus).IGTV were delineated using four approaches: The gross tumor volume (GTV) contours from 10 respiratory phases were combined into IGTV10 ;IGTV2 was acquired by combining the GTV from 0％ and 50％ phases; IGTVMIP was the GTV contour delineated from the maximum intensity projection (MIP) ;IGTV3D was acquired from the enlargement of 3 DCT-based GTV by each spatial direction on the motion amplitude measured in the 4DCT.ResultsTarget movement in lateral (LR),anterio-posterior (AP),superio-inferior (SI) directions showed no statistically significant difference (0.11 cm,0.09 cm,0.18 cm,respectively; χ2 =1.06,P=0.589),and there was no statistically significant difference in centroid positions between IGTV10 and IGTV2 or IGTV3D in group A (t =-2.24,-0.00,P =0.089,- 1.000 ),MI between IGTV10 and IGTV2,IGTV10 and IGTV3D were 0.88,0.54,respectively. For group B, target movement amplitude in SI direction was bigger than in LR, AP ( 0.47 cm,0. 15cm,0. 12 cm,X2= 12.00,P = 0.002).Therewasno significantdifference betweenIGTV10 andIGTV3D inLR, AP, SI ( t =- 0.80.- 0.82,- 1.16,P = 0.450.0.438.0.285 ), MI was 0.59 ; but the target center coordinates was demonstrated significant difference in SI between IGTV10 and ICTV2 for group B ( t = 2.97.P = 0.021 ), Mlwas 0.86.Thevolume of IGTVMIPwassmaller thanIGTV10 ( t =- 2.84,P = 0.025 ), but the position of IGTv10 and ICTVMIp were with no statistically significant difference in the LR,AP,SI ( t =- 0.25,0. 84. - 1.22,P = 0. 809,0.429.0.263 ) ,MIbetweenIGTV10andIGTVMIp was 0.78.Conclusions Patient-specific IGTV can be acquired from 4DCT with correct target coverage while avoiding a geographic miss for the thoracic esophageal cancer,but IGTV2 and IGTVMIP can not contain all the information about primary tumor position,shape.and size at different phases of the respiratory cycle.

OBJECTIVETo explore the diagnosis and treatment and prognosis of sinonasal neuroendocrine carcinoma.

METHODSThe clinical data of 11 cases with sinonasal neuroendocrine carcinoma treated in Zhejiang Cancer Hospital from 1998 to 2010 were analyzed retrospectively. Ten cases were small cell type and one case was atypical carcinoid. One case by only operation, one case by only radiotherapy, one case by only chemotherapy, two cases by radiotherapy and chemotherapy, 6 cases by combined treatment based on surgery (surgery combined with radiotherapy and chemotherapy).

RESULTSAll cases have been followed up for 2 months to 12 years. Six cases by combined treatment one case died in 3 years and one case died in 4 years after treatment, one case has survived without tumor for 12 years and two cases have survived without tumor for 8 years, one case was still in treatment. Five cases of other treatment programs, four cases died in 12 months, one case died in 18 months.

CONCLUSIONSThere's no standard treatment plan. Combined treatment based on surgery should be adopted to nasal neuroendocrine carcinoma. Reccurrence is frequent and the prognosis is poor. The key to improving the survival rate of the disease is early accurate diagnosis and combined treatment.
