Objective To know the primary effect of nutrition intervention in farmers. Methods The questionnaires were used to do baseline and evaluation survey. The intervention ways were used in trial group, including holding lectures, posting posters, sending out healthy material, quizzes with prizes, recommending salts low in sodium to each family, training to make healthy food by the chef; but there were no measures in control group. Results There were statistical significance in healthy awareness of nutrition, exercises and chronic diseases between two groups after intervention; However, the average intake amounts of vegetables did not reach the recommendation of diet guidelines; After intervention, the intake frequency of vegetables and fruits had statistical significance between before and after intervention in trial group, and also had statistical significance in two groups. Conclusion The awareness of healthy knowledge and attitudes has been obvious improvement, but the diets and life styles of farmers have no obvious change. The diet structure and behavior of farmers have been increasingly rational but not enough. The farmers have started to increase the intake times of vegetables and fruits and built up the conception of eating more vegetables and fruits.

Objective To observe the short term therapeutic effects of continuous subcutaneous insulin infusion (CSII) in treatment of type 1 diabetic and type 2 diabetic patients,and compared with intensive therapy of insulin multiple subcutaneous injection by conventional scheme.Methods 48 diabetic patients including 14 cases of type 1 and 34 cases of type 2,were randomly divided into CSII group and control group. In CSII group,the short acting Novolin was subcutaneously infused using insulin pump continuously. In control group,the short acting Novolin was subcutaneously injected before three meals a day and medium acting Novolin was subcutaneously injected before sleep at night.Results Hyperglycemia of the CSII group was depressed,and decreasing degree was similar to that of the control group.However,therapeutic time,insulin dosage and insulin induced hypoglycemia reaction incidence in the CSII group were obviously lower than thoses in control group(P

The M/M/n model of queuing theory can improve efficiency, and then waiting-time that from triage site to specifically sickbed can be shorten consumedly. Conclusion The application and assistance decision on queuing theory in the triage can optimize organization plan and enhance work efficiency.

Objective To investigate the effect of 12-lipoxygenase (12-LO) on the angiotensinⅡtype 1 receptor(ATlR) expression in mesangial cells (MC).Methods p38 MAPK activation and ECM protein expression were determined using AngⅡ-stimulated MC derived from normal and 12-LO knockout mice.AT1R expression was determined using 12-LO product 12(S)- HETE-stimulated MC,MC transfected with 12-LO gene and microdissected glomeruli derived from 12-LO knockout mice.RT-PCR and Western blot were used for evaluating mRNA and protein expression respectively.Results AngⅡstimulation increased p38 MAPK activation and ECM protein expression in normal MC,but not in MC derived from 12-LO knockout mice.Time-dependent and dose-dependent experiment showed that 12 (S)- HETE increased AT1R protein' expression in MC. Similarly,12 (S)-HETE increased AT1R mRNA expression in MC compared with control MC (P＜0.01). Furthermore,AT1R expression was lower in glomeruli derived from 12-LO knockout mice relative to genetic controls (P＜0.01) and MC stably overexpressing 12-LO had greater AT1R protein and mRNA expression relative to control MC (P＜0.01).Conclusion 12-LO activation can upregulate ATIR expression in MC.

Targeting induced local lesions in genomes (TILLING) is a reverse genetics method for functional genomics research.It is possible to screen for point mutations in the populations of EMS mutagenesis with highthroughput and lowcost. EcoTILLING a method based on TILLING ,was developed for detecting multiple types of polymorphisms in germplasm collections,such as single nucleotide polymorphism,small deletion and insertion etc.Rice is a very important food crop and a model plant for genome research also. There are complete genome sequence and a lot of other bioinformatics resources about it.So the markerassisted breeding is becoming more and more important in rice breeding. Some issues based on TILLING about identifying germplasm based on gene sequence,EMS mutagenesis breeding,developing functional marker in rice breeding in future were discussed.

Objective To investigate the imaging findings of the lacerating injury of the lung. Methods Ten patients of lung lacerating injury were examined by X-ray and CT within 1—5 h after injury. X-ray(2—5 times)and CT(3—5 times)examinations were repeated for 7 patients.Results The lung lacerating injury involved 10 sides and 14 lung lobes(21 lesions in total)in the 10 cases,among which 1 case involved the right upper lobe with 1 lesion,2 cases in the right lower lobe with 2 lesions,1 case in the right upper and lower lobes with 2 lesions for each lobe,3 cases in the left lower lobe with 9 lesions,and 3 cases in both the left upper and the lower lobes with 7 lesions.The X-ray findings were cavity-like shadows with smooth margin in 9 lesions(9/21),and patchy shadows of fogging margin in 12 lesions(12/21).The CT imaging findings included 6 pulmonary hematomas(6/21),and 15 cavitary lesions with air-fluid levels (15/21).In the 15 cavitary lesions,CT revealed 14 single cavities and 2 small cavities within a big cavity. On dynamic follow-up observation,the cavity was the biggest in 1—5 h after injury,but the hematoma was the biggest in 2—3 days after injury.Hematomas tended to absorb slower than the cavities.After 16— 32 days,all lesions revolved into small patchy or stripe-like shadows with slightly increased density. Conclusion Cavitary lesion with air-fluid level is the characteristic imaging finding of lung lacerating injury.CT surpasses X-ray plain film in revealing the details of lung lacerating injury.

Objective Studying the status quo and constraints for rural healthcare service in grassroot rural healthcare units,for policy recommendations.Methods Using data from the fourth healthcare service investigation,by means of quantitative interview and qualitative interview,for an investigative interview of 348 township hospitals and 251 village clinics in 31 provinces in China.Results Deployment percentage of primary heahhcare services at township hospitals level is 49.1% (28.0/57),and that for village clinics is 60.6%(5.4/9).Conclusions The key to upgrading rural healthcare service system at grassroots level is to deploy better diagnostic equipments,upgrade the diagnostic competence of grassroots healthcare personnel and build a continuous service system for primary healthcare service.

Objective To document the MRI features of renal angiomyolipoma (RAML) containing minimal fat and to explore whether the MR features vary depending on the tumor size. Methods The MR findings of 15 cases of pathologically-proved RAML containing minimal fat were reviewed retrospectively from January 2008 to March 2010. All patients underwent MR in a 1.5 T or 3.0 T scanners. The MR features of the lesions were analyzed, with emphasis on the signal intensity and homogeneity on T2WI, in regards to pseudocapsule, lipid component, hemorrhage, cystic degeneration or necrosis, blood vessels, interface with renal parenchyma and enhancement pattern. All lesions were categorized into 2 groups; those with diameter ＞4 cm and those with diameter ≤4 cm. The difference of imaging characteristics between these two groups was analyzed using Fisher exact test. Results All 15 lesions demonstrated hypointensity on T2WI compared to the renal parenchyma. Homogeneous signal intensity on T2WI was seen in 6 lesions (6/15); peritumoral pseudocapsule in 3 lesions (3/15); cystic degeneration or necrosis, hemorrhage in 5 lesions (5/15); flow void of blood vessels in 2 lesions (2/15); lipid component in 4 lesions (4/15); angular interface with renal parenchyma in 10 lesions (10/15); homogeneous enhancement in 8 lesions (8/15). Fifteen lesions were divided into two groups; 9 categorized into group 1 (the maximum diameter ≤ 4 cm) and 6 into group 2 ( the maximum diameter ＞ 4 cm). Cystic degeneration or necrosis was seen in 0 of 9 in group one and 5 of 6 in group two respectively, hemorrhage(0 of 9 and 5 of 6 respectively) and pseudocapsule(0 of 9 and 3 of 6 respectively. The difference between these findings in the two groups demonstrated statistical significance (P ＜ 0. 05). Conclusion The MR features of RAML containing miminal fat were hypointensity on T2 WI,angular interface with renal parenchyma and homogeneous contrast enhancement, however, these findings can vary depending on the tumor size.
