OBJECTIVETo study the relationship between pathogenesis for Yin-deficiency of acute myocardial infarction (AMI) and immediate prognosis as well as its neuro-endocrine mechanism.
METHODSAccording to the TCM standard of Syndrome Differentiation of Deficiency Syndrome, 194 patients with AMI were classified into the typical Yin-deficiency group (n = 26), the non-typical Yin-deficiency group (n = 61) and the non-Yin-deficiency group (n = 107). Their venous blood samples were collected in the morning while lying on their backs to detect plasma levels of adrenaline, noradrenaline, aldosterone, atrial natriuretic peptide (ANP), corticoid and myocardial enzymes, as well as their hospitalization days and mortality in hospitalized period were calculated and compared in the three groups, with the 30 healthy persons as control.
RESULTSLevels of serum creatine phosphokinase, creatine phosphokinase isozyme, plasma adrenaline, noradrenaline, aldosterone, hospitalization days and mortality were higher in the Yin-deficiency groups than in the non-Yin-deficiency group (P < 0.05, P < 0.01). As compared the indexes between the typical and the non-typical Yin-deficiency groups, significant difference only showed in plasma aldosterone and ANP, which was significantly higher in the former (P < 0.05, P < 0.01). Plasma corticoid level was insignificantly different between the Yin-deficieny groups.
CONCLUSIONPatients with AMI of Yin-deficiency type was severer in myocardial damage, with longer hospitalization period and higher mortality, it is probably due to the hyper-activated sympathetic-adrenaline system and strengthened activity of aldosterone in them.

Objective:
To investigate the epidemiology of iron-deficiency anemia among children aged 0-6 years in plateau area,and to provide a basis for the formulation of prevention and treatment measures for anemia.
Methods:
A total of 1 512 children aged 0-6 years were randomly selected from 4 counties in plateau area by stratified and cluster sampling. Blood hemoglobin level was tested. Child dietary behaviors were collected from their parents.
Results:
There were significant differences in the prevalence of children with different age, family location, education level of main dependants, occupation of main dependants and per capita income of family(χ2=12.83,39.48,27.05,44.26,32.45, P<0.05).No significant difference for anemia prevalence in gender and nationality was found. The prevalence of anemia among children aged 0-6 years was 67.0%, and the prevalence was highest among children aged 1 years while decreased with age.Univariate analysis of variance showed that the prevalence anemia was 74.0% in rural children, which was significantly higher than children in urban area 58.6%(χ2=39.48,P<0.05). Low education and income level of caregiver, husbandry in the family, no exclusive breastfeeding under 6 months, and picky eaters positively associated with high prevalence of anemia. The prevalence rate of anemia in 0-6 months old infants fed with mixed feeding and artificial feeding (73.1%, 75.0%) was higher than that of breast feeding (48.9%) (χ2=6.78, P<0.05). Picky eating can lead to a high incidence of anemia in children.
Conclusion
Promoting healthy diets and correcting unhealthy dietary pattern through nutrition education to parents might be effective ways to lower the prevalence of anemia among children in plateau areas.

Objective: To explore whether acupuncture can improve sleep disturbance, cognitive impairment and emotional disorders caused by sleep deprivation, and its association with the attenuation of oxidative stress injury in prefrontal cortex. Methods: Fifty-two male Sprague-Dawley rats were randomly divided into a control group (n=10), a model group (n=14), a manual acupuncture (MA) group (n=14), and a sham-MA group (n=14). All the groups were established as sleep deprivation models via the modified multiple platform method, except for the control group. Rats in both the MA group and the sham-MA group received corresponding intervention, respectively. After modeling and intervention, the four groups received three behavioral tests, namely sleep monitoring, by comprehensive lab animal monitoring system (CLAMS), Morris water maze (MWM) test and open-field test (OFT), followed by oxygen free radical level test and Western blot (WB) detection for the expression levels of Bax and Bcl-2. Results: The MA group derived more sleep time within 24 h than either the model group or the sham-MA group (both P<0.05). On MWM orientation navigation test day 1, there were no significant differences in escape latency among the control, MA and sham-MA groups (P>0.05), and the escape latency was significantly shorter in these three groups than that in the model group (all P<0.05). On test day 4, the escape latency was markedly shorter in the MA group than that in either the model group or the sham-MA group (both P<0.05); meanwhile, the MA group showed significantly better performance compared with these two groups in space probe test (both P<0.05). In OFT, compared with the control group, there was a significant decline in the horizontal movement score in the other three groups (all P<0.05), and the decrease was more significant in the model group and the sham-MA group than that in the MA group (both P<0.05). The superoxide dismutase (SOD) content was markedly higher and the malondialdehyde (MDA) content was markedly lower in the MA group than those in the model group and the sham-MA group (all P<0.05). Compared with the model group and the sham-MA group, the expression of Bax was significantly lower and the expression of Bcl-2 was significantly higher in the MA group (all P<0.05). Conclusion: MA therapy can lengthen the sleep time in sleep-deprived rats and improve learning and memory impairments induced by sleep deprivation, and the underlying mechanism may be associated with the enhancement of antioxidant capacity in the prefrontal cortex and the inhibition of hippocampal neuronal apoptosis.

Objective To investigate the prevalence of overweight and obesity in Chinese ninth grade students and to analyze the influential factors that contribute to this situation. Methods A total of 5 967 students were selected from the 2016 China Education Panel Survey. Chi-square test was used to examine the differences in the prevalence of overweight and obesity among different groups and Logistic regression models were used to analyze the factors affecting obesity in boys and girls. Results The prevalence of overweight and obesity was 15.23%, 18.55% and 11.84% in total, male and female ninth grade students respectively. The multiple Logistic regression analysis indicated that the risk factors between boys and girls were significantly different. The main factors affecting boys obesity rate were one-child, boarding, both parents obesity, taking health education courses, having indoor stadium and screen time. Meanwhile, for girls the factors were boarding, both parents obesity and sports time. Conclusions Schools should arrange the schedule of boarding students and offer health education courses based on the characteristics of boys and girls. Meanwhile schools should unite parents to control adolescents’ screen time and nutrition balance, which is benefit for preventing adolescents overweight and obesity.

OBJECTIVE The purpose of the present study was to investigate the impact of fluvas-tatin formulation on the pharmacokinetics-genetic polymorphis relationship. METHODS We compared the difference between the pharmacokinetics of fluvastatin as an extended-release (ER) 80 mg tablet and an immediate-release(IR)40 mg capsule in terms of drug metabolism enzyme and transporter ge-netic polymorphisms. In this open-label, randomized, two-period, two-treatment, crossover study, ef-fects of BCRP, SLCO1B1, MDR1, CYP2C9, and CYP3A5 polymorphisms on the pharmacokinetics of fluvastatin were analyzed in 24 healthy individuals.Each treatment duration was 7 days with a washout period of 7 days between the crossover.Serum concentration of fluvastatin was evaluated using high-performance liquid chromatography-tandem mass spectrometry. RESULTS The SLCO1B1 T521C genotype had no statistically significant effect on IR 40 mg capsule of fluvastatinafter single or repeated doses.However,for the ER 80 mg tablet,the SLCO1B1 T521C genotype correlated with the AUC0-24of repeat doses (P=0.01). The CYP2C9*3 genotype correlated with the AUC0- 24after the first dose IR 40 mg capsule (P<0.05); however, the difference between CYP2C9*1/*1 and CYP2C9*1/*3 was not statistically significant after repeated doses. CONCLUSION The effect of SLCO1B1 T521C on fluvas-tatin exposure was observed and was more profound in ER and repeated dose administration than in IR and single dose administration.We recommend that formulation should be incorporated into future pharmacogenomics studies and clinical implication guidelines.
