Objective To establish the diagnostic criteria of deficiency of Qi and Yin in IgA nephropathy by combining Delphi method with analytic hierarchy process.Methods After literature research,an item pool of Qi and yin deficiency syndrome was formed.Based on this item pool and expert discussion,an expert questionnaire was formed.Two rounds of Delphi method were used to conduct expert questionnaire survey,and then the weight value of the items was calculated by AHP.Finally,a diagnostic questionnaire of Qi and yin deficiency syndrome in IgA nephropathy was formed,which laid a foundation for the final formation of diagnostic criteria.Results Through Delphi and analytic hierarchy process,the following 12 items and their weights were finally obtained:①mental fatigue:13.1205%;②Weak waist and knees:7.8514%;③Dry mouth or throat:10.6984%;④Hand foot heart heat:8.985%;⑤Tinnitus:4.0495%;⑥Susceptible to cold:8.8027%;⑦Spontaneous or night sweat:9.4594%;⑧Yellow or red urine:4.7458%;⑨Pale red tongue:6.906%;⑩Fat tongue:7.159%;?Less moss or thin white moss:8.947%;?Weak or thin pulse:9.275%.Conclusion Through the combination of Delphi method and analytic hierarchy process,the qualitative analysis and quantitative evaluation of each item of Qi and yin deficiency syndrome in IgA nephropathy were carried out,and the best item and specific weight of Qi and yin deficiency syndrome in IgA nephropathy were obtained,providing a reference for the formation of future standards.

Objective To investigate the effect of tonifying kidney and promoting pharynx prescription on IgA nephropathy model rats and the mechanism of regulating the TLR4 signaling pathway.Methods After SD rats were randomly divided into groups,the rat model of IgA nephropathy was replicated.After the medication,urinary RBC,UTP,blood creatinine,urea nitrogen,renal tissue TLR4,MyD88,NF-κB,MCP-1 expression,C1GALT1 and cosmoc mRNA expression in peripheral blood,TLR4,NF-κB and IL-6 in serum were observed.Results ①Compared with the blank group,urinary RBC,UTP,and renal tissue TLR4,MyD88 and NF-κB,MCP-1 expression,C1GALT1 and cosmoc mRNA expression in peripheral blood,TLR4,NF-κB and IL-6 in serum increased in the model group(P<0.05).②Compared with the model group,UTP,urinary RBC,renal tissue TLR4,MyD88 and NF-κB,MCP-1 expression,C1GALT1 and cosmoc mRNA expression in peripheral blood,the content of TLR4 and NF-κB,IL-6 were decreased(P<0.05)in tonifying kidney and promoting pharynx prescription group;There was no significant change in renal function.Conclusions ①The tonifying kidney and promoting pharynx prescription can effectively reduce hematuria and proteinuria in rats with IgA nephropathy.②The tonifying kidney and promoting pharynx prescription can reduce renal injury by improving the immune response mediated by TLR4 Signal transduction system induced by mucosal infection and reducing abnormal glycosylation IgA1 by adjusting key enzyme C1GalT1 and molecular companion Cosmc in IgA1 glycosylation process.
RÉSUMÉ
Objective@#To explore the relationship between nutritional status and puberty onset in boys, and to provide a reference for promoting the development of physical and mental health of boys.@*Methods@#A total of 2 724 boys aged 7 to 12 years from grade 2 to 6 were recruited from Xiamen city by cluster sampling method in 2017. The nutritional status was assessed by physical examination, pubertal developmental status was evaluated by rating scales of Tanner and Prader orchidometer, and puberty timing was determined by the P25 age of puberty onset. The association between nutritional status and puberty onset was estimated by logistic regression model.@*Results@#Pubertal onset was found in 29.0% of the boys and the incidence of early pubertal timing was 2.9%. The prevalence of puberty onset in wasting, normal weight, overweight and obesity boys was 19.6%, 28.7%, 34.4% and 31.5%, respectively. The age of puberty onset was significantly earlier in obese boys (F=3.23, P<0.05). The results of Logistic regression analysis showed that with the increase of BMI, the possibility of puberty onset and risk of early pubertal timing increased. After adjusting for confounding factors, the odds of puberty onset in boys with wasting decreased by 64.0% (OR=0.36, 95%CI=0.22-0.60), the possibility of puberty onset and risk of early pubertal timing in boys with obesity increased by 78.3% (OR=1.78, 95%CI=1.14-2.79) and 192.9% (OR=2.93, 95%CI=1.46-5.86), respectively. These relationships were more pronounced in boys of households with lower economic level (P<0.05).@*Conclusion@#BMI was positively correlated with puberty onset in boys, the odds of puberty onset and risk of early pubertal timing were significantly increased in obese boys, especially in those with low household economic level.
