Objective: To understand the trends in malnutrition among primary and middle school students of Han nationality in Hainan Province from 2005 to 2019, so as to provide a basis for improving nutrition intervention measures for children and adolescents. Methods: A sample of 32 949 Han nationality primary and middle school students aged 7-18 years old in Hainan Province were investigated in 2005, 2010, 2014 and 2019 based on national survey on student physical fitness and health. The Malnutrition Screening Standard of Schoolage Children and Adolescents was used to screen malnutrition. Statistical analysis was performed using the χ2 test and the χ2trend test. Results: In the four surveys conducted during 2005 to 2019, the prevalence of malnutrition among primary and middle school students were 22.12%, 18.80%, 15.89% and 9.56%, respectively, with an increase of -12.56% and an average annual increase of -5.82%. The decreasing trend of malnutrition by year was statistically significant (χ2trend=600.72, P<0.01), and the proportion of emaciation type was the highest (8.87%-20.15%). The detection rates of malnutrition among all students aged 7 to 18 showed a decreasing trend from 2005 to 2019 (χ2trend=56.44, 60.04, 61.48, 42.49, 51.81, 50.81, 72.86, 101.34, 86.38, 24.81, 17.72, 10.38, P<0.01). From 2005 to 2019, the detection rates of malnutrition in boys were higher than that of girls (in 4 surveys), and that in rural students from 2005 to 2014 of 3 surveys were higher than that in towns (χ2=92.07, 35.16, 25.29, 29.98; 64.35, 4.26, 6.32, P<0.05). Conclusions The malnutrition of Han nationality primary and middle school students aged 7-18 years in Hainan Province show a trend of improvement year by year from 2005 to 2019, despite the overall high detection rate. Wasting is the most common type of malnutrition. The epidemic of malnutrition varies by age, sex and areas. Further targeted measures should be taken to strengthen intervention in the diet of primary and middle school students, to improve the nutritional status of children and adolescents.

ObjectiveTo explore the therapeutic effect and mechanism of the Danhe granules on hypercholesterolemia rats by observing the changes in the efficacy indicators and the levels of proteins related to the cholesterol metabolism pathway in the rats under the intervention of Danhe granules. MethodSD rats were randomly assigned to either the blank group or the model group based on their body weight. The blank group had normal chow diets， while the model group was fed high-fat diets for seven weeks. One week after the establishment of the model， the content of the serum total cholesterol （TC） in the model rats was detected. According to the TC value， the model group was further randomly divided into a control group， pravastatin sodium tablet group（4.02 mg·kg^-1）， Xuezhikang capsule group（0.12 g·kg^-1）， high-dose， middle-dose， and low-dose groups of Danhe granules（4.536， 2.268， 1.134 g·kg^-1）. After grouping the model groups， each treatment group received continuous oral gavage for six weeks， with weekly measurements of body weight and food intake （the difference between feed intake and feed surplus）. Six weeks later， the levels of serum TC， triglyceride （TG）， low-density lipoprotein cholesterol （LDL-C）， and high-density lipoprotein cholesterol （HDL-C） were measured. The liver pathology and lipid droplet distribution were evaluated by hematoxylin-eosin （HE） staining and oil red O staining， with scoring and calculation conducted. Rat liver tissue was collected， and western blot and immunohistochemistry （IHC） were used to detect the expression levels of cholesterol metabolism-related proteins namely phosphorylated adenosine 5'-monophosphate （AMP）-activated protein kinase （p-AMPK）， AMPK， 3-hydroxy-3-methyl glutaryl coenzyme A reductase （HMGCR）， low-density lipoprotein receptor （LDLR）， cholesterol 7α-hydroxylase （CYP7A1）， Acyl-coenzyme A： cholesterol acyltransferase 2 （ACAT2）， and apolipoprotein B （ApoB） in hypercholesterolemia rats. ResultCompared with the blank group， the model group showed a significantly higher level of serum TC （P<0.01）. The TG level had no significant change， and the HDL-C level was significantly decreased （P<0.05）. The liver index， steatosis score， total score of pathological state， and the positive area ratio of oil red O staining were significantly increased （P<0.01）， and the protein expression levels of p-AMPK， p-AMPK/AMPK， LDLR， and CYP7A1 were significantly decreased （P<0.05， P<0.01）， while the protein expression levels of AMPK， HMGCR， and ACAT2 were significantly increased （P<0.05， P<0.01）. Compared with the model group， the TC level in each dose group of Danhe granules was significantly decreased （P<0.05）， and the positive area ratio of oil red O staining in the pravastatin sodium tablet group and medium-dose group of Danhe granules was significantly decreased （P<0.05）. In each administration group， the protein expression levels of p-AMPK and p-AMPK/AMPK were significantly increased （P<0.05， P<0.01）， and the levels of HMGCR and ACAT2 were significantly decreased （P<0.01）. The ApoB level showed a downward trend. The CYP7A1 level in the pravastatin sodium tablet group and each dose group of Danhe granules was significantly increased （P<0.05， P<0.01）， and the LDLR level in the pravastatin sodium tablet group， Xuezhikang capsule group， and high-dose and medium-dose groups of Danhe granules was significantly increased （P<0.05， P<0.01）. ConclusionDanhe granules can reduce serum TC levels and improve hepatic steatosis. It may activate AMPK， down-regulate the expression of HMGCR， and inhibit cholesterol synthesis. It can also up-regulate the expression of LDLR and CYP7A1， promote cholesterol uptake and excretion， down-regulate the expression of ACAT2 and ApoB， reduce cholesterol absorption and assembly of LDL and other lipoproteins， and thus play a role in the treatment of hypercholesterolemia.

Talents are the main force for the development of traditional Chinese medicine（TCM）， and the construction of TCM talents and the reformation of talent evaluation system are essential to promote the inheritance and innovation of TCM. At present， we are still exploring and developing in the fields of the formulation， implementation and evaluation indicators of TCM talent evaluation system. However， there are shortcomings and difficulties. For instance， insufficient stratification in the evaluation， excessive emphasis on the quantity of achievements， neglecting the quality of the achievements and the actual contribution， imperfect assessment indicators， and the weak characteristics of TCM. Therefore， national ministries and commissions have jointly issued a document requesting to break the four only and set a new standard， in order to promote the construction of a scientific and technological talent evaluation system oriented by innovation value， ability and contribution. For the evaluation of TCM clinical talents， China Association for Science and Technology commissioned China Association of Chinese Medicine to build the China Clinical Cases Library of TCM（CCCL-TCM）， which aims at collecting the most authoritative and representative TCM clinical cases and exploring the advantages of applying clinical cases as masterpiece of achievement in TCM clinical talents evaluation. CCCL-TCM can promote the construction of a talent evaluation system that is more in line with the development characteristics of TCM industry， and to carry out relevant pilot in TCM colleges and institutions across the country in order to promote the reformation of TCM talent evaluation system.
