Objective:To explore the risk factors of thyroid nodules in diabetic patients and its correlation with Traditional Chinese Medicine (TCM) constitution.Methods:A Total of 213 cases of diabetic patients in Guang’anmen Hospital and Tangshan Hospital from January 2019 to August 2020 were choosen to do the questionnaire, with containly symptom and constitution. The patients were divided into diabetes with thyroid nodules group and diabetes without thyroid nodules group according to whether thyroid nodules were combined. We compared the clinical data characteristics of 2 groups, and used multi-factor logistic regression model to analyze the risk factors of diabetic patients with thyroid nodules and their correlation with TCM constitutions. Results:Diabetes patients aged from 50-80 years old [ OR=2.949, 95% CI (1.266-6.714)], females [ OR=3.736, 95% CI (1.823-1.541)], diabetes duration≥15 years [ OR=1.558, 95% CI (1.623-1.585)], elevated HbA1c [ OR=5.862, 95% CI (1.418-23.629)], elevated VLDL [ OR=2.851, 95% CI (1.597-6.824)], frequent insomnia [ OR=1.970, 95% CI (1.315-3.395)], Qi stagnation [ OR=4.357, 95% CI (2.634-8.377)], blood stasis [ OR=4.420, 95% CI (1.874-15.258)] are more likely to suffer from thyroid nodules ( P<0.05). Conclusion:Diabetic patients aged from 50-80 years old, females, diabetes duration≥15 years, elevated HbA1c, family history of thyroid nodules, frequent insomnia, and mood swings are more likely to develop thyroid nodules; qi stagnation and blood stasis are dangerous constitutions for diabetic patients with thyroid nodules.

Data based on the antiviral-resistant phenotyping characteristics of 884 influenza B viruses circulating in mainland China from October 2013 to March 2014 were analyzed to assess the susceptibility of influenza B viruses to neuraminidase inhibitors. All 884 viruses were sensitive to oseltamivir; two viruses (0.23%) had reduced sensitivity to zanamivir and all other viruses were sensitive to zanamivir. Among the 38 viruses with a B/Victoria lineage, B/Shandong-Kuiwen/1195/2014 exhibited a half-maximal inhibitory concentration (IC50) for zanamivir that was elevated by 5. 12-fold (1.78 nM) compared with neuraminidase inhibitors sensitive to the reference virus (0.34 nM), suggesting that it exhibited reduced inhibition by zanamivir. D35G, N59D and S402T (39, 64 and 399 with N2 number) amino-acid substitutions in the NA gene were detected with no previously reported antiviral-resistant substitutions. Among viruses with the 846 B/Yamagata lineage, B/Hunan-Lingling/350/2013 exhibited a 7.99-fold elevated IC50 for zanamivir (2.72 nM) compared with neuraminidase inhibitors sensitive to the reference virus (0.34 nM), suggesting that it exhibited reduced inhibition by zanamivir. D197N (N2 number), a previously reported antiviral resistant-related amino-acid substitution in the NA gene, was detected in B/Hunan-Lingling/350/2013. These data suggest that recently circulating influenza B viruses in mainland China have retained susceptibility to neuraminidase inhibitors.

To analyze the antigenic and genetic characteristics of the influenza A (H3N2) virus in mainland China during the surveillance year of 2013-2014, the antigenic characteristics of H3N2 virus were analyzed using reference ferret anti-sera. The nucleotide sequences of the viruses were determined by Sanger dideoxy sequencing, phylogenetic trees were constructed with the neighbor-joining method, and the genetic characteristics of the viruses were determined in comparison to current vaccine strains. The results showed that most of the H3N2 viruses were antigenically closely related to the A/Victoria/361/2011 vaccine strain cell-propagated prototype virus (99.6%). Using the A/Texas/50/2012 egg isolate as the reference antigen, 15.1% of the viruses were found to be closely antigenically related to it, while 11.9% of strains were closely antigenically related to the egg-propagated epidemic strain, A/Shanghai-Changning/1507/2012. Phylogenetic analysis of HA genes indicated that the A(H3N2) viruses in this surveillance year were in the same clade, but no drug resistant mutation was identified in the NA genes. During the 2013-2014 influenza surveillance year, no significant genetic change was detected in either the HA or NA genes of the A(H3N2) viruses, while significant mutations were found in egg isolates resulting from their adaptation during propagation in eggs. The antigenic and genetic changes should be investigated in a timely manner to enable the selection of an appropriate vaccine strain in China.
