2.Different concentration of iodized salt for preventing iodine deficiency disorder: a systematic review
Chinese Journal of Endemiology 2009;28(5):579-582
Objective To assess the effectiveness of different concentration of iodized salt for preventing iodine deficiency disorders. Methods Using the principle and method of systematic review, we searched Cochrane Library(from 1994 to Mar. 2007), Medline(from 1966 to Mar. 2007), BA(from 1969 to Mar. 2007), PubMed(from 1950 to Mar. 2007), OC1D(from 1950 to Mar. 2007), ISI Web of Knowledge(from 1966 to Mar. 2007), Vip (from 1989 to Mar. 2007), Wanfang(from 1997 to Mar. 2007), CBMDisc(from 1978 to Mar. 2007) and CNKI(1994 to Mar. 2007) and hand searched 6 relevant Chinese journals, including Chinese Journal of Preventive Medicine, Chinese Journal of Endemiology, Chinese Journal of Epidemiology, Chinese Journal of Control of Endemic Disease, Endemic Diseases Bulletin and Modern Preventive Medicine. We screened the for eligible studies according to the inclusion and exclusion criteria to be rigorously evealuatecl descriptly and qualitatively. Results Thirteen studies were included, of which, the first six were intervention trials with comparison, including two community intervention trials, which classified all objects into different groups, using iodized salt at different concentration as intervention, four were RCTs with different intervention methods, compare the iodized salt with other intervention measures. Seven were cross-sectional studies, which analyzed the iodine nutrition of people after the concentration of iodized salt was lowered down. Because of different interventions in control groups and different outcome measures, it was difficult to perform recta-analysis, a descriptive analysis of the results was presented. Most studies showed that urinary iodine level decreased as the concentration of iodized salt went down gradually. When the concentration of iodized salt went down to the best level recommended, goiter rate decreased obviously. Conclusions Iodized salt was considered as the hest method of iodine supply to prevent iodine deficiency disorders. But effectiveness of preventing iodine deficiency disorders with various concentration of iodized salt is different. To lower the concentration of iodized salt properly can not only prevent iodine deficiency disorders but also reduce the side effect of excess iodine intake to the minimum. And it can also save a lot of iodine resource. Well-designed community-based intervention trials with large sample size are needed to confirm the effect of different concentration of iodized salt on preventing iodine deficiency disorder.

Chinese Traditional and Herbal Drugs 2020;51(13):3465-3472
Objective: The relevant indicators of energy metabolism in rats with heat syndrome were tested to verify the medicinal properties of Descurainia sophia and its nature and flavor splitting components, in order to explain the cold and heat properties of D. sophia and its splitting components. Methods: Healthy male Sprague-Dawley rats were randomly divided into normal control group (NC), model group (M), water extract of gardenia (DS), flavonoid glycosides composition of D. sophia (FG), flavonoid aglycone composition of D. sophia (FA), oligosaccharide resolution component group (Oli), gardenia polysaccharide decomposition component group (Pol), and D. sophia fatty oil component separation group (FO). The model of heat syndrome was established by intragastric administration of Euthyrox (120 mg/kg). After 15 days of continuous administration, blood was taken from the abdominal aorta and the liver and heart were taken to detect the indicators related to the energy metabolism of the substance. The enzyme expression of glucokinase (GCK) and fructose phosphokinase (PFK-1), phosphoglycerate kinase (PGK), pyruvate kinase (PK), pyruvate dehydrogenase (PDH), acetyl-CoA, citrate synthase (CS), isocitrate dehydrogenase (ICD), alpha-ketoglutarate dehydrogenase (alpha-KGDHC), fumarate (FUM), glycogen phosphorylase (PYGL), glycogen synthase kinase-3 (GSK-3), adipose triglyceride lipase (ATGL), cytochrome C reductase (CCR), cytochrome C oxidase (COX), ATP synthase (ATPs), adenylate kinase (ADK), Na+ K,+-ATPase and the content of adenosine triphosphate (ATP), adenosine diphosphate (ADP), nicotinamide adenine dinucleotide (NAD+), reduced nicotinamide adenine dinucleotide (NADH) were determined. Results: Compared with NC group, the weight of M group rats was decreased significantly (P < 0.01). Compared with M group, the body weights of rats in DS, FG, FA, Pol and tFO groups were significantly or highly significantly increased (P < 0.05, 0.01). Compared with NC group, the number of spontaneous activities in M group was increased significantly (P < 0.01) within 5 min, and the number of locomotor activities of each group within 5 min after administration was significantly decreased (P < 0.01). Compared with NC group, the levels of GCK, PFK-1, PK, PGK, PDH, acetyl-CoA, CS, ICD, α-KGDHC, FUM, PYGL, GSK-3, ATGL, ATP, CCR, COX, ATPs, ADK, Na+ K,+-ATP, NADH expression or content in M group of rats were significantly increased (P < 0.05, 0.01), the content of ADP, NAD+ and NAD+/NADH was decreased (P < 0.05, 0.01). After administration, the expression level of material energy metabolism of the rats in each group was significantly or extremely significantly reduced compared with the M group (P < 0.05, 0.01). Conclusion: D. sophia can improve the state of the energy-metabolism related indicators of the rats in the heat syndrome model group. It is verified that D. sophia nature and flavor splitting components show the cold (cool) properties. From the side, it reflects the mechanism of "treating heat with cold drug" is related with the substance energy metabolism.

Previous studies showed that three methods for regulating and invigorating lung and kidney (lung invigorating and spleen strengthening, lung invigorating and kidney tonifying, and Qi supplementing and kidney nourishing) could regulate inflammatory signaling pathways of chronic obstructive pulmonary disease (COPD) in rats, so as to alleviate inflammation. In the present study, R-value comprehensive evaluation method was used to evaluate the comprehensive effect of three methods for regulating and invigorating lung and kidney on inflammatory signaling pathways. Rats were randomly divided into control, model, lung invigorating and spleen strengthening, lung invigorating and kidney tonifying, Qi supplementing and kidney nourishing and aminophylline groups. The COPD rat models were established by cigarette smoking combined with bacterial infection, and orally administered with drugs between the 9th and 20th week. Afterwards, efforts were made to observe the long-term effects between the drug withdrawal and the 32rd week and detect indicators in two batches in the 20th week and 32th week. Specifically, (1) Linking JAK/STAT signaling pathway: JAK2 mRNA, and protein expressions of STAT-1, STAT-3, STAT-5, JAK-2; (2) NF-kappaB signaling pathway: Smad2 mRNA and protein expressions of I-kappaB, NF-kappaB, TGF-beta1; (3) PPARgamma and antioxidant signaling pathway: SOD, PGE mRNA, PPARgamma protein. According to the results, 5 indicators in JAK/STAT pathway, 4 indicators in NF-kappaB pathway, and 3 indicators in PPARgamma pathway were significantly rectified by three methods for regulating and invigorating lung and kidney in between the 20th week and 32nd week. Between the 20th and 32nd week, the recipes for rectifying JAK/STAT pathway with intensity from high to low were recipes for lung invigorating and spleen strengthening, Qi supplementing and kidney nourishing, lung invigorating and kidney tonifying, aminophylline, particularly those for lung invigorating and spleen strengthening; The recipes for rectifying NF-kappaB pathway with intensity from high to low were recipes for lung invigorating and spleen strengthening, lung invigorating and kidney tonifying, Qi supplementing and kidney nourishing and aminophylline, particularly the first three types of drugs. The recipes for rectifying PPARgamma and antioxidant signaling pathway with intensity from high to low were recipes for lung invigorating and kidney tonifying, Qi supplementing and kidney nourishing, lung invigorating and spleen strengthening and aminophylline. Therefore, three methods for regulating and invigorating lung and kidney showed better long-term effects in regulating COPD lung inflammation signaling pathways. Specifically, recipe for lung invigorating and spleen strengthening showed a better effect in JAK/STAT and NF-kappaB pathways, while recipe for lung invigorating and kidney tonifying and Qi supplementing and kidney nourishing showed better effects in PPARgamma and antioxidant signaling pathways. In conclusion, R-value comprehensive evaluation method can evaluate the comprehensive effect of medicines and define the ranking of multiple drugs and their main targets.

OBJECTIVESTo explore whether the angiotensin I -converting enzyme (ACE) I/D (insertion/ deletion) polymorphism is associated with the susceptibility to high altitude pulmonary edema (HAPE) in the Han Chinese.
METHODSOne hundred and forty-seven HAPE-p (HAPE patients) and 193 HAPE-r (HAPE resistants) were enrolled from the Yushu earthquake reconstruction workers in Qinghai province where the altitude is over 3 500 m above sea level. Blood samples were collected from each of the HAPE-p and HAPE-r groups. Information about physiological phenotypes was obtained via fieldwork investigation. The ACE-I/D polymorphism in HAPE-p and HAPE-r was detected by polymerase chain reaction (PCR).
RESULTSThe SaO2 was significantly lower while HR was significantly higher in HAPE-p group than those in HAPE-r group. The genotype frequencies of ACE-I/D for II, ID, DD in HAPE-r and HAPE-p groups were 0.430, 0.446, 0.124 and 0.435, 0.469, 0.095, respectively, the allelic frequencies of I and D were 0.650, 0.350 and 0.670, 0.330, respectively. The OR of ID, DD and D alleles relative to II for HAPE was 0.961 (0.610-1.514), 1.322 (0.634-2.758) and 1.080 (0.783-1.489). There was no significant difference of the genotypic and the allelic frequencies in ACE-I/D polymorphism between HAPE-p and HAPE-r groups.
CONCLUSIONSThere is no relation between ACE-I/D polymorphism and HAPE in the Han Chinese.
