The situation of investment in health is a measure of socio-economic and cultural development of a country or region.The health outcome from a certain amount of health costs is the economic benefits of investment in health.The World Health Organization has made "put investment in the field of health to promote economic development," a new development strategy for the purpose of investment in health,expanding domestic demand and the development of health which could be the cause of national macro-economic development.This paper briefly describes the impact of health investment on China's economic development from several aspects.

ObjectiveTo investigate the effect of early induced finger function training on motor function and activities of daily living (ADL) of stroke patients.Methods60 stroke patients with hemiplegia were randomly divided into the early induced finger function training group (treatment group) and control group with 30 cases in each group. The patients of the control group were treated with routine rehabilitation; while those of the treatment group were added with training of early induced flexion and extension of fingers. All patients of two groups were assessed with Brunnstorm Scale, Fugl-Meyer Assessment, scores of Neurological Functional Deficit, and Modified Barthel Index before and 8～12 weeks after treatment.ResultsAfter treatment, upper limb motor function, hand function and fingers' fine function in the sick side of the patients in the treatment group improved significantly better than that in the control group ( P<0.05～0.01).ConclusionThe early induced finger function training can obviously improve the upper limb motor function and ADL of stroke patients.

Objective To compare the tumor sizes of primary lesions in pancreatic cancer based on CT scan and postoperative pathological analysis and measure the extent of filtration under a microscope,and to determine the CTV in radiotherapy target delineation.Methods A total of 19 patients with pancreatic cancer who were admitted to PLA General Hospital and Air Force General Hospital,PLA from 2013 to 2014 were analyzed.In 15 patients,the maximum diameters of tumor cross-section were measured based on the images of preoperative multi-slice spiral CT and postoperative gross samples,respectively.In 19 patients,the extent of tumor infiltration was measured on pathological sections under a microscope and the actual extent of infiltration was calculated.The paired t-test was applied to analyze the differences in the results of different measurement methods.Results In the 15 patients,the maximum tumor diameters measured with gross samples and CT scan were 33.6 mm and 30.1 mm,respectively (P=0.000),and the median and mean of the differences were 3.1 mm (1.2-8.0 mm) and 3.6±2.0 mm,respectively (95％ CI 1.2-6.0).In the 19 patients,the maximum actual infiltration distance and the maximum distance measured were 3.50 mm and 3.19 mm,respectively (P=0.000),and the median and mean of the differences were 0.31 mm (0.15-0.50 mm) and 0.30±0.09 mm,respectively.The maximum distance between the margin of primary lesions and the infiltrating lesions was 5.21 mm,with a median of 3.34 mm (2.19-5.21 mm) and a mean of 3.50± 0.88 mm (95％ CI 2.19-5.06).Conclusions Contrast-enhanced CT scan underestimates the actual size of primary lesions in pancreatic cancer,and an extension of 5 mm outside gross tumor volume (GTV) as CTV may not be sufficient.It is recommended to extend another 1-3 mm outside GTV as CTV.

OBJECTIVETo explore the effect of emodin on endoplasmic reticulum (ER) stress of pancreatic acinar AR42J cells.

METHODRat pancreatic acinar AR42J cells were cultured in 6-well plates, and divided into the normal control group, the model group (with the final concentration at 1 x 10(-7) mol · L(-1) for cerulean and lipopolysaccharide at 10 mg · L(-1)) and the emodin group (10, 20, 40 μmol · L(-1)). Cells in each group were cultured in three multiple pores for 24 h, and their supernate was removed after cell attachment. The normal control group was added with haploids, the model group was added with the modeling liquid for haploids, and the treatment groups were added with different concentrations of emodin at 15-20 min before the modeling liquid. The cells were continuously cultured for 3 h under 37 °C and 5% CO2. Their intracellular protease and lipase expressions were detected with kits. The cellular morphology was observed under optical microscope. The level of calcium in endoplasmic reticulum was measured under laser confocal microscopy. Western blot assay were used to determine the protein expression of ER-related signaling molecules.

RESULTEmodin could significantly inhibit levels of amylase, lipase and intracellular calcium and ER.

CONCLUSIONEmodin could reduce pancreatic acinar cell injury induced by the combination of cerulean and lipopolysaccharide. Its action mechanism is correlated with the inhibition of intracellular calcium overload and ER stress.

Objective:To explore the application of OTSU-based self-attenuation correction PET (sacPET) reconstruction technology in 18F-florbetapir (AV45) imaging. Methods:From November 2018 to December 2019, 7 confirmed Alzheimer′s disease (AD) patients (4 males, 3 females, age (69.6±4.5)years) and 3 healthy controls (HC; 1 male, 2 females, age (68.0±4.6) years) were recruited prospectively for 18F-AV45 PET imaging in the First Affiliated Hospital of Sun Yat-Sen University. Original data collected by PET acquisition was processed with sacPET reconstruction and then compared with standard PET images by visual analysis and semi-quantitative analysis. Fisher exact test, Kappa test and Pearson correlation analysis were used to analyze data. Results:In HC group and AD group, the radioactive distribution showed by sacPET images and that by standard PET images were similar, and the contrast of gray-white matter in sacPET images was weaker than that in standard PET images. Moreover, the positive uptake area of the cortex in the AD group was smaller than that in standard PET images. Visual analysis showed 19 positive regions in sacPET images and 22 in standard PET images, with no statistical difference of positive rates of the sub-regions in the cortex between the two PET images (all P>0.05), and the overall consistency of 88.00% (44/50; Kappa=0.75 (95% CI: 0.57-0.94), P<0.05). Semi-quantitative analysis showed that the standardized uptake value ratio (SUVR) of frontal lobe and cingulate gyrus measured by sacPET was lower than that measured by standard PET (0.93±0.06 vs 0.96±0.06 and 0.99±0.04 vs 1.01±0.04; t values: 5.30 and 5.10, both P<0.01), while SUVR of parietal lobe, temporal lobe and occipital lobe measured by sacPET was higher than that measured by standard PET (0.78±0.08 vs 0.68±0.07, 0.97±0.07 vs 0.91±0.08 and 0.94±0.11 vs 0.71±0.12; t values: 6.27, 7.36 and 16.90, all P<0.01). The overall SUVR of sacPET images was significantly correlated with the standard PET images ( r=0.75, P<0.001). Conclusion:For 18F-AV45 imaging, sacPET reconstruction technology can obtain reliable and effective PET images without CT data, but its accuracy and precision still need to be improved.
