Objective Taking nurses relative number prediction for example,this paper discussed the application of Information Renewal GM (1,1)—Linear Regression Coupling Model in the prediction of health personnel resources,so as to provide methodology reference for forecasting health personnel.Methods The information renewal GM(1,1) and linear regression coupling model was built and explored to predict and fit analyzing.Results The error between the predictive value that calculated by information renewal GM(1,1) and the actual value was small,and the prediction accuracy of coupling model was high.Conclusion The coupling model not only remedied the defect that grey system model did not including linear factors,but also improved the fact that linear forecasting model could not express exponential growth.Therefore the coupling model was reasonable and feasible.

Objective To evaluate the research input-output efficiency of 15 medical universities,and provide references for improving synthetic research efficiency.Methods Selected research input-output key indicators,and used CCR model and SE-DEA model to statistic and analyze.Results The average value of comprehensive efficiency of 15 medical universities was 0.811,pure technical efficiency value was 0.978,scale efficiency value was 0.827.There were 5 DEA efficient universities,7 pure technical efficient universities among 10 Non-DEA efficient universities.Conclusion The total research efficiency of medical universities in our country remained to improve,and should emphasize adjusting scientific research scale.

Scientificly forecasting the health resources is the premise and foundation for making health resource planning.This paper summarized the application scope and characteristics of commonly used statistical models for health resources forecasting,introduced many S type curve prediction models commonly used in natural and social economic fields,hackled and concluded the weight calculation methods of combination forecasting models,and on this basis put forward that multivariable time series model or combination forecasting model based on single time series model and multi-linear regression equation of the predictive value should be set up for forecasting health resources,so as to provide methodological references for related forecasting research.

Objective To assess the equity of health resources configuration in Zhejiang,and provide references for regional health planning.Methods The Lorenz curve,Gini coefficient and Theil index were used to calculate and analyze.Results The Gini coefficient in 2009-2011 calculated by population density was between 0.330～0.343,which meant comparatively rational.The main reason of inequity configuration for hospital beds and nurses was inter-regional difference.Conclusion The Theil index could remedy the disadvantage that Gini coefficient could not reflex the total inequity was brought up by inter-regional or intra-regional difference.The health resource configuration should based on population health need and health service demand.

Objective To study the value of clinical application of leukocyte classification alarm system (Q‐Flag ) for Sysmex XT‐1800i blood cell analyzer .Methods 394 blood samples with alarm system (Q‐Flag) and 190 ones without abnormal alarm infor‐mation detected by the Sysmex XT‐1800i blood cell analyzer were performed to observe the quantity and morphology of blood cells by manual differentiation ,and the results were compared between them .Results The alarm system of Sysmex XT‐1800i blood cell analyzer in detecting cell morphologic abnormalities was 100 .0% for sensitivity ,62 .3% for specificity ,70 .8% for positive predic‐tive value and 100 .0% for negative predictive value .Based on thegold standardof manual differentiation ,no abnormal cells were observed in those blood samples without Q‐Flag alarm information and the coincidence rate was 100% .The coincidence rate of leu‐kocyte classification was from 0 .0% to 75 .0% for blood cell analyzer when the alarm system (Q‐Flag) was between 100U and 200U ,and that was from 66 .7% to 95 .6% when the alarm system (Q‐Flag) was between 200U and 300U .Conclusion The alarm system sensitivity of leukocyte classification alarm system (Q‐Flag) is high for Sysmex XT‐1800i blood cell analyzer ,and it is nec‐essary to manually differentiate the samples with abnormal Q‐Flag in order to provide accurate and reliable clinical diagnostic infor‐mation .

Background:Colorectal polyps are common gastrointestinal diseases,which are closely related to the development of colorectal cancer. Aims:To investigate the clinical features of high-risk people with intestinal polyps in colorectal cancer screening. Methods:People in Hongkou District,Shanghai,who were positive in fecal occult blood test or of the high risk category in colorectal cancer questionnaire from April 2013 to December 2014 were enrolled,and colonoscopy was performed at Branch of Shanghai First People’s Hospital. The overall detection rate,gender,age,location of lesion, morphology,and pathology were analyzed. Results:A total of 985 patients with colorectal polyps were recruited in this study. The overall detection rate of polyps was 48. 7% . The prevalence of colorectal polyps was significantly higher in males than in females(58. 7% vs. 38. 9% ;χ2 = 79. 788,P < 0. 01). The detection rates of colorectal polyps in different age groups were statistically significant(χ2 = 23. 820,P < 0. 01). Detection rate of polyps was significantly higher in left colon than in right colon(62. 4% vs. 37. 6% ;χ2 =190. 643,P <0. 01). The overall detection rate of protruding lesion 0-Ⅰwas 94. 5% ,and slightly elevated lesion 0-Ⅱa was 48. 3% . Detection rate of adenomatous pylops was significantly higher than non-adenomatous pylops(59. 3% vs. 47. 1% ;χ2 = 27. 326,P < 0. 01). The histological results were differed between two examination in 119 patients. Only 17. 8% of the patients operated were followed up by colonoscopy,and polyps recurred in 62. 3% of them. Conclusions:A higher incidence of colorectal polyps is found in people with high risk of colorectal cancer screening. High quality colonoscopy examination and effective operation in time can reduce the incidence of colorectal cancer.

Objective To investigate the prevalence of colorectal cancer in community people in Shanghai,and clarify the necessity of colorectal cancer screening in community residents.Methods From April 2013 to September 2014,colonoscopy examination was carried out in people who participated in colorectal cancer screening in Shanghai with positive result of fecal occult blood test or with high-risk in colorectal cancer evaluated with the risk factors questionnaire.A total of 1 990 individuals were recruited.The colonoscopic results of them were retrospectively analyzed.Chi-square test was performed for statistical analysis.Results The 1 990 individuals received colonoscopy examination aged from 50 to 92.Among the 1 990 individuals with colonoscopy examination,colorectal polyps,colorectal cancer and carcinoid were found in 1 027 cases,and the total detection rate was 51.6％.The detection rate of colorectal polyps was 48.7％ (969/1 990),and the maximum diameter of polyps was 3.5 cm.The detection rate of colorectal polyps of the male was 59.3％ (532/897),which was higher than that of the female (40.0％,437/1 093),and the difference was statistically significant (x2 =73.7,P＜0.01).The detection rate of colorectal polyps in group 50 to 60 (not include 60) years old,60 to 70 (not include 70) years old,70 to 80 (not include 80) years old and ≥80 years old was 37.5％ (139/371),48.7％ (524/1 075),55.9％ (248/444) and 58.0％ (58/100),respectively.The difference was statistically significant (x2 =31.3,P＜0.01).The detection rate of colorectal cancer was 2.7 ％ (54/1 990).The detection rate of male rectal cancer was 3.8％ (34/897),which was significantly higher than that of female (1.8％,20/1 093),and the difference was statistically significant (x2 =7.2,P＜0.05).The detection rate of colorectal cancer in group 50 to 60 (not include 60) years old,60 to 70 (not include 70) years old,70 to 80 (not include 80) years old and ≥80 years old was 1.6％ (6/371),1.9％ (20/1 075),4.3％ (19/444) and 9.0％ (9/100),respectively.The difference was statistically significant (x2 =23.7,P＜0.01).The detection rate of rectal carcinoid was 0.2 ％ (4/1 990).Conclusions The prevalence of colorectal polyps and cancer is high in screening community people with high-risk of colorectal cancer.Colorectal cancer screening in community people ≥ 50 years old with sequential screening method is important.
