Because of the rapidly rhythm of modern society, fast food and take-out become the main dining methods for most of young people,while the outside foods always have few types of foods and nutrition is not complete. Nutrient imbalances may cause many diseases such as gastrointestinal diseases,cardiovascular diseases,diabetes,obesity,and cancer.In this environment,health products have emerged.At present,there are a wide variety of health care products at home and abroad,which are broadly divided into three categories:traditional vitamins,emerging nutrient products,and extracts of natural plant active ingredients.In the early 1970s,the sales of health products in the United States had reached 170 million dollars.At present,it has nearly 100 billion dollars,which is almost 1/3 of the total food sales, people's demand for health products is increasing rapidly. In recent years, Chinese medicine health products become more popular in western,in fact, Chinese medicine health products have a long history of application in China and have a good reputation in the folk. Obviously, Chinese medicine health products have great potential for development.So this article mainly compared the de-velopment and state of health products between China and west countries.Based on the development of health products in western countries, this article analyzes the development trend and prospects for the development of Chinese medicine health products. It is roughly divided into three parts. The first part introduces the development reasons and history of western health products development.The sec-ond part introduces the history of Chinese health products and the current situation of Chinese medi-cine health products. The third part guesses the development trend of Chinese medicine health prod-ucts and provides some development ideas. The purpose of this airticle is to provide reference and ideas for the future research and development of traditional Chinese medicine health products.

Objective To explore the clinical significance of detecting serum levels of IL-6 and TNF-α in patients with intracranial hemorrhage.Methods The serum levels of IL-6 and TNF-α in different period were detected in patients with intracranial hemorrhage, by enzyme-linked immunosorbent assays (ELISA), and compared with those of healthy subjects (the control group).ResultsThe serum levels of IL-6, TNF-α in the severe and slight patients of study group on 1st, 3rd, 5th and 7th were signiifcantly higher than those in the control group (all withP<0.05). The serum levels of IL-6, TNF-α in the severe patients of study group were signiifcantly higher than those in slight patients of study group (all withP<0.05) on 5th and 7th. The serum levels of IL-6 and TNF-α in dead cases on 5th, 7th days admission were significantly higher than those in survival cases (P<0.05). The serum levels of IL-6 was positively correlated with TNF-α (r=0.721,P<0.05).Conclusion The detection of dynamically serum levels of IL-6 and TNF-α is of great clinical value for assessing the disease development therapeutic efifcacy and prognosis of brain injury patient with intracranial hemorrhage.

OBJECTIVETo investigate the role of p38 MAPK on ischemic postconditioning (IPO) attenuating pneumocyte apoptosis after lung ischemia/reperfusion injury (LIRI).

METHODSForty adult male SD rats were randomly divided into 5 groups based upon the intervention (n = 8): control group (C), LIR group (I/R), LIR + IPO group (IPO), IPO + solution control group (D), IPO + SB203580 group (SB). Left lung tissue was isolated after the 2 hours of reperfusion, the ratio of wet lung weight to dry lung weight (W/D), and total lung water content (TLW) were measured. The histological structure of the left lung was observed under light and electron transmission microscopes, and scored by alveolar damage index of quantitative assessment (IQA). Apoptosis index (AI) of lung tissue was determined by terminal deoxynuleotidyl transferase mediated dUTP nick end and labeling (TUNEL) method. The mRNA expression and protein levels of and Bax were measured by RT-PCR and quantitative immunohistochemistry (IHC).

RESULTSCompared with C group, W/D, TLW, IQA, AI and the expression of Bax of I/R were significantly increased, the expression of Bcl-2 and Bcl-2/Bax were significantly decreased (P < 0.05, P < 0.01), and was obviously morphological abnormality in lung tissue. Compared with I/R group, all the indexes of IPO except for the expression of Bcl-2 and Bcl-2/ Bax were obviously reduced, the expression of Bcl-2 and Bcl-2/Bax were increased (P < 0.05, P < 0.01). All the indexes between D and IPO were little or not significant( P > 0.05). The expression of Bcl-2 and Bcl-2/Bax of SB were significantly increased and other indexes were reduced than those of IPO (P < 0.05, P < 0.01).

CONCLUSIONIPO may attenuate pneumocyte apoptosis in LIRI by inactivation of p38 MAPK, up-regulating expression of Bcl-2/Bax ratio.

OBJECTIVETo investigate the effect of siRNA silencing the role of C-Jun N-terminal Kinase (JNK) gene in excessive endoplasmic reticulum stress on lung ischemia/reperfusion injury.

METHODSMouse model of pulmonary ischemia reperfusion injury (PIRI) in situ was established with unilateral lung in vivo. Seventy experimental mice were randomly allocated into seven groups (n = 10): Sham group (Sham group), ischemia reperfusion group (I/R), PBS+ Lipofectamine2000TM transfection reagent group (I/R + PBS+ Lipo group), negative control group (I/R+ SCR group), JNK-siRNA group (I/R + siRNA(JNK1), siRNA(JNK2), siRNA(JNK3)). Mice were euthanized after experimental time out, and left lung tissue was extracted. Wet/dry lung weight ratio (W/D) and total lung water content (TLW) were tested. Light microscope, alveolar damage quantitative evaluation index (IQA) and electron microscope were observed. The expression levels of JNK and glucose regulatex protein(GRP78) were detected by RT-PCR and Western blot. Apoptosis of lung tissue was determined by TUNEL.

RESULTSCompared with Sham group, all indicators above of I/R + PBS + Lipo group and I/R + SCR group were significantly increased (P < 0.01), and compared with I/R group, those indicators of the three groups all had no notable difference; those indicators were not statistically different between I/R + PBS + Lipo group and I/R + SCR group, and compared to the three groups, the above indicators in JNK-siRNA group were lower (P < 0.05, P < 0.01) except that the expression levels of GRP78 was not statistically different.

CONCLUSIONI/R induces excessive ERS in lung tissue, in which JNK pathway participates in apoptosis, leading to lung tissue injury.

Objective To retrospectively determine the features of stones and calcifications in hepatobiliary system on virtual nonenhanced (VNE) dual-energy computed tomography (CT), and to evaluate the possibility of VNE images in diagnosis for those lesions.Methods A total of 128 gall stones and calcifications of the liver found in 110 patients were examined with triple phase abdominal CT scan from July 2007 to December 2011, in which true nonenhanced (TNE) phase and arterial phase were performed with single-energy CT (120 kVp) and portal venous phase was performed with dual-energy CT (100 kVp and 140 kVp). VNE images were generated from the portal venous phase dual-energy CT data sets by using commercially VNC software. The mean CT values for the stone, liver, bile and paraspinal muscle, mean lesion density and size in area dimension, contrast-to-noise ratio (CNR) of lesion to the liver or bile, and image noise were assessed and compared between VNE and TNE images. The effective dose and size-specific dose estimate (SSDE) were also calculated.Results The mean CT values of the lesions measured on VNE images declined significantly compared with those measured on TNE images (164.51±102.13 vs. 290.72±197.80 HU, P<0.001), so did the lesion-to-liver CNR (10.80±11.82 vs.18.81±17.06, P<0.001) and the lesion-to-bile CNR (17.24±14.41 vs. 21.32±17.31, P<0.001). There was no significant difference in size of lesions area between VNE and TNE images (0.69±0.88 vs. 0.72±0.85 cm, P=0.062). Compared to the 128 lesions found in TNE images, VNE images showed the same density in 30 (23.4%) lesions, lighter density in 88 (68.8%) lesions, while failed to show 10 (7.8%) lesions, and showed the same size in 61 (47.7%) lesions and smaller size in 57 (44.5%) lesions. The CT cutoff values of lesion and size were 229.21 HU and 0.15 cm, respectively. The total effective dose for triple phase scan protocol with TNE images was 19.51±7.03 mSv, and the SSDE was 39.84±11.10 mGy. The effective dose for dual phase scan protocol with VNE images instead of TNE images was 13.29±4.89 mSv, and the SSDE was 27.83±9.99 mGy. Compared with TNE images, the effective dose and SSDE of VNE images were down by 32.05%±3.69 % and 30.63%±2.34 %, respectively.Conclusions Although the CT values and CNR of the lesions decreased in VNE images, the lesions of which attenuation greater than 229.21 HU and size larger than 0.15 cmcould be detected with good reliability and obvious dose reduction. There was good consistency in the size of stones and calcifications in hepatobiliary system between VNE images and TNE images, which ensured the possibility of the clinical application of VNE images.

Objective To know the quality of iodized salt and the current situation of the salt coverage in Tibet,and to provide scientific basis for proposing proper prevention and control measures to Iodine dificiency disorders(IDD). Methods In 2008, according to the "Sampling Methods of the Main Products in the Salt Industry",one batch fifteen salt samples were collected in iodized salt processing factory in Tibet. Five townships were chosen in each county based on 5 different directions of east, south, west, north and center. If the monitoring county has less than five townships, then all of the townships were sampled. In each township, four villages were selected withrandom sampling and importance sampling. In each township, 15 households were selected for salt collection. Results A batch of 15 salt samples in a salt processing plant were tested, and all of them were qualified with salt iodine(34.6±1.58) mg/kg. A total of 21 107 edible salt samples were tested, and 11 203 of them were qualified iodized salt. These results meant that the provincial iodized salt coverage rate was 53.08%. Shannan iodized salt coverage rate was 94.31% (3395/3600) which was the highest in Tibet. Those of Nagqu, Changdu, Ngari were lower, they were 29.84% (897/3006), 24.94% (823/3300) and 17.08% (205/1200), respectively. Conclusions The quality of iodized salt in Tibet is up to the national standard, but the coverage rate of iodized salt is very low.We suggest that the strategy should be carried out according to the national overall program strategy and supplement iodized oil capsule for special groups.

Objective: To understand health literacy and associated factors of freshmen from Jiangsu Province, and to provide reference for youth health education. Methods: From 2017 October to 2018 October, a total of 15 602 college freshman were randomly selected from 20 universities in Jiangsu Province via stratified cluster sampling method. Structural questionnaires were used to investigate the status of health literacy. The χ 2 test and multivariate Logistic regression model were used to analyze the influencing factors of health literacy. Results: The health literacy level of college freshmen from Jiangsu Province was 20.2%, among which the literacy levels of knowledge, behavior and skills were 23.0%, 30.7% and 31.5% respectively. The literacy levels of the six public health issues, including safety and first aid, scientific health attitude, knowledge of prevention and treatment of infectious diseases, health information, basic health care, and prevention and treatment of chronic diseases, from high to low, were 72.8%, 58.7%, 28.5%, 28.2%, 20.3% and 15.9%, respectively. Multivariate Logistic regression analysis has showed that students from undergraduate colleges(OR=2.77, 95%CI=2.47-3.11), urban areas(OR=1.20, 95%CI=1.07-1.34), or southern Jiangsu regions(OR=1.10, 95%CI=1.00-1.22), being the only child(OR=1.13, 95%CI=1.03-1.25), higher maternal education level (OR=1.53, 95%CI=1.30-1.79), having both parents(OR=1.16, 95%CI=1.00-1.34), reported higher level of health literacy. Conclusion The three aspects and six dimensions of health literacy of college freshmen were unbalanced. Health literacy is a shared function of multiple factors including society, family, and individuals. It is essential to promote health education through more efforts on key issues, in order to effectively elevate the health literacy level of adolescent students.
