Relationship between catecholamine level and gene polymorphism of β1 adrenergic receptor G1165C in children with EV71 infection in hand foot and mouth disease

Objective:To investigate the relationship between the levels of plasma adrenaline and norepinephrine and gene polymorphism of β1 adrenergic receptor G1165 C in children with enterovirus 71(EV71) infection in hand foot and mouth disease(HFMD). Methods:The polymerase chain reaction(PCR) was used to detect the expression of gene polymorphism of β1 adrenergic receptor G1165 C in vitro. The levels of plasma adrenaline and norepinephrine were measured by enzyme-linked immunosorbent assay(ELISA). Results:The plasma norepinephrine level of severe group was significantly higher than the mild group in children with EV71 infection in HFMD(P<0.05); however,the levels of plasma adrenalinein in two groups had no statistical differences(P>0.05); There was no significant difference in the distribution of β1 adrenergic receptor G1165 C genotype and allele between EV71 infection group and healthy control group(P> 0.05). Further analysis of EV71 infection group by dividing it into mild and severe groups showed that there was no significant difference in the distribution of genotype and allele between these two groups as well(P> 0.05). There was no significant difference in the levels of epinephrine and norepinephrine in different genotypes of EV71 infection group(P> 0.05),and in the levels of plasma epinephrine and norepinephrine in the mild and severe groups(P> 0.05). Conclusions:As the disease gets worse,the plasma norepinephrine level has a rising trend in children with EV71 infection in HFMD,which is an important indicator to evaluate the progress of the disease. However,the gene polymorphism of eptor G1165 C have no significant correlation,not only with the susceptibility and severit β1 adrenergic recy of EV71 infection in hand,foot and mouth disease,but also with the levels of catecholamine.

Consensus on the integrated traditional Chinese and Western medicine criteria of diagnostic classification in polycystic ovary syndrome(draft)

Polycystic ovary syndrome （PCOS） is the most common endocrine and metabolic disorder of women, with complex pathogenesis and heterogeneous manifestations. Professor Jin Yu recently wrote an article entitled ＂Proposal of Diagnosis and Diagnostic Classification of PCOS in Integrated Traditional Chinese and Western Medicine.＂ From this, the Obstetrics and Gynecology branches of the Chinese Association of Integrative Medicine and the China Association of Chinese Medicine collaborated with the Gynecology branch of the Chinese Association for Research and Advancement of Chinese Medicine to draft a report on the consensus of criteria for the diagnosis and classification of PCOS in integrated traditional Chinese and Western medicine. The diagnosis for PCOS includes all three features： （1） oligo-ovulation or anovulation; （2） clinical and/or laboratory evidence of hyperandrogenism; （3） PCOS is classified into four types： types la, Ib, Ila, and lib. Syndrome differentiation types for PCOS in traditional Chinese medicine are as follows： Kidney deficiency with phlegm blockage syndrome, Kidney Yin deficiency with phlegm blockage and blood stasis syndrome, and Kidney deficiency with Liver Qi stagnation syndrome.
