[Summary] A total of 215 pregnant women at mid-gestation were enrolled, and their serum 25-hydroxyvitamin D levels were measured. Of them, 38 (17. 7%) were classified as cases with vitamin D sufficiency, 70 (32. 5%) as insufficiency, and 107 (49. 8%) as deficiency. Compared with the sufficient group, parathyroid hormone level increased and osteocalcin level decreased significantly in the deficient group. Therefore, vitamin D deficiency is highly prevalent among pregnant women and is associated with their potential disorder of bone turnover.

The diagnosis and treatment characteristics of head-wind sha in She medicine were analyzed and summarized. By visiting She-nationality villages and towns in Zhejiang province and Fujian province and interviewing hundreds of doctors of She medicine, the sha diagnosis, sha differentiation, experience and theory of treatment were arranged, and a comprehensive summary on theory and application of head-wind sha in She medicine such as pathogeny, name of disease, mechanism, diagnosis, differential diagnosis and treatment was made. It is believed that the methods of diagnosis and treatment in She medicine for head-wind sha could effectively enhance curative effect, safety and patients' quality of life, and the further research should be carried out.

Objective To investigate the relationship between iodine nutritional status and thyroid hormone levels,and to provide a guideline for monitoring iodine nutrition and thyroid function.Methods A crosssectional survey was performed by randomly selecting 341 samples (health pregnant women with a first child) from the Second People's Hospital of Guiyang,Bihai Community Medical Center and Jinhuayuan Community Center from October 2015 to September 2016.Levels of serum hormones and antibodies relative to throid of pregnant women in Guanshan Lake District of Guiyang at different pregnant times,which included throid stimulating hormone (TSH),free three triiodothyronine (FT3),free thyroxine (FT4),thyroid peroxidase antibody (TPOAb),and thyroglobulin antibody (TgAb),were measured by the electrochemical luminescence method,and urinary iodine levels were measured by heat digestion.Results The median urinary iodine of pregnant women at early,middle and late stages (T1,T2 and T3 stages) were 191.8,198.9 and 214.5 μg/L,respectively.FT3 increased first and then decreased during pregnancy.Levels of FT3 in the T2 stage were significandy higher than those in T1 and T3 stages (FT3 medians at the three stages were 4.49,4.83 and 4.57 pmol/L),and the differences were statistically significant (P < 0.05).FT4 levels decreased during pregnancy (FT4 medians at the three stages were 16.32,14.65 and 13.22 pmol/L),and the differences among the three groups were statistically significant (H =67.517,P < 0.01).Statistically significant differences were not found in the TSH levels among the three groups ~SH medians at the three stages were 2.05,2.01 and 2.39 mU/L,H =1.297,P > 0.05).The medians of TPOAb and TgAb during T2 stage (9.60 and 19.02 U/ml) were significantly lower than those of other groups (18.92 and 24.75 U/ml at stage T1,and 13.46 and 22.06 U/ml at stage T3),and the differences were statistically significant (P < 0.05).TSH levels were consistent with urinary iodine levels.TSH levels in the excessive iodine group (urine iodine:250 ~ 499 μg/L,2.54 mU/L) were significantly higher than those in the adequate iodine group (urine iodine:150 ~ 249 μg/L,1.97 mU/L) and deficient iodine group (urine iodine:< 150 μg/L,1.91 mU/L),and the differences were statistically significant (P < 0.05).No correlations were found between levels of FT3,FT4,TPOAb,TgAb and levels of the urinary iodine.There was a significant positive correlation between urinary iodine levels and TSH levels (rs =0.180,P < 0.01).The incidence of abnormal thyroid function in pregnant women was 29.33% (100/341),which was composed of clinical hypothyroidism (accounting for 0.88%,3/341),subclinical hypothyroidism (accounting for 25.51%,87/341),low T4 level (accounting for 1.76%,6/341),clinical hyperthyroidism (accounting for 0.59%,2/341),subclinical hyperthyroidism (accounting for 0.59%,2/341),and TPOAb positive and TgAb positive (accounting for 12.61%,43/341).These abnormalities occurred mainly in the T1 and T3 stages.The prevalence of subclinical hypothyroidism increased with increasing of urinary iodine level,and the difference was statistically significant (x2 =11.269,P < 0.05).Conclusion There is a positive correlation between pregnancy iodine nutritional status and its TSH level,so it is important to monitor the level of urinary iodine during pregnancy and to screen the thyroid function and antibodies in the early and middle time of pregnancy.

Objective To investigate the changes of serum thyroid peroxidase(TPOAb)and thyroglobulin antibody(TGAb)and their relationship with thyroid function in pregnant women during different gestation period Methods Totally 341 cases of primiparae were selected from October 2015 to September 2016 and levels of se-rum thyrotropin(TSH),free triiodothyronine(FT3),free thyroxine(FT4),thyroid peroxidase antibody(TPOAb) and thyroglobulin antibody(TgAb)were measured by electrochemiluminescence. Results The prevalence of thy-roid dysfunction and positive serum thyroid autoantibodies were 13.2%and 12.61%respectively,which mainly oc-curred in early and middle pregnancy. Thyroid dysfunction in subjects included hypothyroidism(0.59%),subclini-cal hypothyroidism(7.92%),low T4 hyperlipidemia(3.23%),hyperthyroidism(0.88%)and subclinical hyper-thyroidism(0.59%). The positive rate of TPOAb was significantly higher than that of TgAb(10.85% vs. 4.99%, P<0.01). The positive rate of TPOAb in women with thyroid disfunction was significantly higher than that in those with normal thyroid function(44.44%vs. 5.74%,P<0.01). TSH level of TPOAb positive subjects was higher than that of TPOAb negative ones(P<0.05,P<0.01);TSH level of TPOAb positive subjects with thyroid dysfunction were significantly higher than those of TPOAb negative subjects and TPOAb positive pregnant women but with nor-mal thyroid function(P < 0.01). The hypothyroidism prevalence rate of TPOAb positive subjects was significantly higher than that of TPOAb negative subjects in early and middle stage of pregnancy (P < 0.01). The prevalence rates of subclinical hypothyroidism ,low T4 hyperlipidemia and clinical hypothyroidism were significantly higher in TPOAb positive pregnant women(29.17%,20.83% and 8.33%)than those in TPOAb negative pregnant women (P < 0.01). Conclusions Thyroid dysfunction is closely related to positive status of TPOAb and TgAb in pregnancy,which could influence the outcome of pregnancy and the development of offspring. Since levels of TSH, FT3 and FT4 could not fully reveal thyroid function ,it is necessary to monitor the status of TPOAb and TgAb as early as possible for the early diagnosis and treatment of thyroid disease in pregnancy.

Heart failure with preserved ejection fraction (HFpEF) displays normal or near-normal left ventricular ejection fraction, diastolic dysfunction, cardiac hypertrophy, and poor exercise capacity. Berberine, an isoquinoline alkaloid, possesses cardiovascular benefits. Adult male mice were assigned to chow or high-fat diet with L-NAME ("two-hit" model) for 15 weeks. Diastolic function was assessed using echocardiography and noninvasive Doppler technique. Myocardial morphology, mitochondrial ultrastructure, and cardiomyocyte mechanical properties were evaluated. Proteomics analysis, autophagic flux, and intracellular Ca2+ were also assessed in chow and HFpEF mice. The results show exercise intolerance and cardiac diastolic dysfunction in "two-hit"-induced HFpEF model, in which unfavorable geometric changes such as increased cell size, interstitial fibrosis, and mitochondrial swelling occurred in the myocardium. Diastolic dysfunction was indicated by the elevated E value, mitral E/A ratio, and E/e' ratio, decreased e' value and maximal velocity of re-lengthening (-dL/dt), and prolonged re-lengthening in HFpEF mice. The effects of these processes were alleviated by berberine. Moreover, berberine ameliorated autophagic flux, alleviated Drp1 mitochondrial localization, mitochondrial Ca2+ overload and fragmentation, and promoted intracellular Ca2+ reuptake into sarcoplasmic reticulum by regulating phospholamban and SERCA2a. Finally, berberine alleviated diastolic dysfunction in "two-hit" diet-induced HFpEF model possibly because of the promotion of autophagic flux, inhibition of mitochondrial fragmentation, and cytosolic Ca2+ overload.
