Objective To analyze the monitoring results of iodine deficiency disorders (IDD) of Dehong State in 2017,to find out the present situation of prevention and control of IDD,and to provide scientific basis for guiding the comprehensive prevention and control of IDD in our state in the future.Methods According to "Yunnan Iodine Deficiency Disorders Monitoring Program",a sampling survey was conducted in 5 counties (cities) of Dehong State,Yunnan Province.Urine and household salt samples were collected from children aged 8 to 10 years old and pregnant women in Mangshi,Lianghe County and Yingjiang County.Iodine content was detected.In addition,household salt samples of Ruili City and Longchuan County were collected to detect iodine content.Results There were 1 609 salt samples from local inhabitants,the coverage rate of iodized salt was 99.19％ (1 596/1 609),the edible rate of qualified iodized salt was 95.03％ (1 529/1 609) and the median of iodized salt was 23.76 mg/kg.The median of urinary iodine in 623 children aged 8 to 10 years old was 221.34 μg/L and the thyroid enlargement rate was 0.48％ (3/623).The median of urinary iodine in 346 pregnant women was 159.52 μg/L.Conclusion The iodine nutrition of children aged 8 to 10 years old and pregnant women of Dehong State is appropriate in 2017.

OBJECTIVETo analyze the genetic characterization of enterovirus type71 (EV71) associated with hand foot and mouth disease (HFMD) epidemics in Jilin province, during 2009-2010.

METHODSRandomly selected 31 representative EV71 strains from the cases of 8 prefectures to amplify and sequences of VP1 genes of EV71 strains, and analyzed with Bioedit and Mega4.0 program.

RESULTSAll representative 31 EV71 strains belong to C4a subgenotype, the homology of nucleotide in VP1 region among the 31 EV71 strains were 94. 5%-100. 0%, and were clustered into 5 transmission chains respectively. 25 strains out of 31 strains were associated with a predominant transmission chain, and circulating in 8 prefectures, while other 6 strains clustered into 4 lineages.

CONCLUSIONMultiple transmission chains of EV71 C4a subgenotype were co-circulating in Jilin province during 2009-2010, and a predominant transmission chain was circulating in 8 prefectures, associated with HFMD outbreaks of Jilin province.

OBJECTIVE: To assess the efficacy and safety of Guanxin Danshen Dripping Pills (GXDS) in the treatment of depression or anxiety in patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI). METHODS: From September 2017 to June 2019, 200 CHD patients after PCI with depression and anxiety were included and randomly divided into GXDS (100 cases) and placebo control groups (100 cases) by block randomization and a random number table. Patients in the GXDS and control groups were given GXDS and placebo, respectively, 0.4 g each time, 3 times daily for 12 weeks. The primary outcomes were scores of Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Scale (GAD-7) and the Seattle Angina Pectoris Scale (SAQ). The secondary outcomes included 12 Health Survey Summary Form (SF-12) scores and the first onset time and incidence of major adverse cardiovascular events (MACEs). Other indices including blood pressure, blood lipids, microcirculation and inflammatory-related indices, etc. were monitored at baseline, week 4, and week 12. RESULTS: In the full analysis set (200 cases), after treatment, the PHQ-9 and GAD-7 scores in the GXDS group were considerably lower than those in the control group (P<0.05). Compared with the baseline, the total PHQ-9 scores of the experimental and control groups decreased by 3.97 and 1.18, respectively. The corrected mean difference between the two groups was -2.78 (95% CI: -3.47, -2.10; P<0.001). The total GAD-7 score in the GXDS group decreased by 3.48% compared with the baseline level, while that of the placebo group decreased by 1.13%. The corrected mean difference between the two groups was -2.35 (95% CI: -2.95, -1.76; P<0.001). The degree of improvement in SAQ score, SF-12 score, endothelin and high-sensitive C-reactive protein levels in the GXDS group were substantially superior than those in the placebo group, and the differences between the two groups were statistically significant (P<0.05). Similar results were obtained in the per protocol population analysis of 177 patients. Three cases of MACES were reported in this study (1 in the GXDS group and 2 in the placebo group), and no serious adverse events occurred. CONCLUSIONS GXDS can significantly alleviate depression and anxiety, relieve symptoms of angina, and improve quality of life in patients with CHD after PCI. (Registration No. ChiCTR1800014291).
