Objective To analyze the clinical and pathological characteristics of thyroid carcinoma in patients from Qilu Hospital of Shandong University in last 7 years,and to explore the changes in disease spectrum.Methods Records of 772 patients with thyroid carcinoma,who underwent thyroidectomy and pathological examination,were reviewed from January 2005 to December 2011.Results (1) Individuals suffering from thyroid carcinoma have increased rapidly during these 7 years.(2) The high incidence of the disease resided in the age group of 30-59 for both men and women,with a male-to-female ratio of 1 ∶ 2.73.(3) The proportion of papillary microcarcinoma showed a growing trend,the rising trends were also apparent in papillary thyroid cancer (PTC) coexisting with nodular goiter or Hashimoto's thyroiditis (HT).Papillary microcarcinoma accounted for27.27％ of all PTC in 2005 and reached 54.22％ in 2011.Coexistence of PTC and HT accounted for 12.38％ of the cases with a male-to-female ratio of 1 ∶ 6.Conclusion The occurrence of thyroid carcinoma,especially papillary microcarcinoma has been increasing in recent years.The coexistence of PTC with nodular goiter or HT showed a trend to increase.

Objective To explore the intervention effect of low-dose vitamin D on glucose metabolism of patients with impaired glucose regulation. Methods A total of196 subjects receiving oral glucose tolerance test were enrolled in this study, including individuals with normal glucose tolerance ( NGT group, n=67) and indi-viduals with impaired glucose regulation (IGR group, n=129). The IGR group was divided into intervention group ( n=64) and non-intervention group ( n=65) according to vitamin D intervention ( for 1 year) performed or not. Clinical data and biochemical parameters were collected. Results The level of serum 25(OH)D3 was significantly lower in the IGR group than that of normal control group ( P<0. 05) . After 1 year of low-dose vita-min D intervention, insulin sensitivity increased and insulin resistance decreased in the intervention group as compared with non-intervention group. Diabetes developed less frequently in the intervention group ( 25 of 64 [ 39. 1％] ) compared with non-intervention group ( 30 of 65 [ 46. 2％] ) . But there was no significant differ-ent in diabetes prevalence between the two groups. Conclusions Vitamin D intervention can improve insulin sensitivity and reduce insulin resistance in patients with impaired glucose regulation. Low dose vitamin D can improve the abnormal glucose metabolism outcome in patients with impaired glucose regulation.

Objective To investigate the effects of yoga exercise on exercise capacity, anxiety and depression in patients with acute myocardial infarction. Methods 75 patients with emergency PCI in Cardiology Department of a Class Ⅲ Grade A hospital in Zhengzhou from January to December in 2017 were seclected as subjects and randomly divided into control group (n=37) and intervention group (n=38) by convenient sampling. The control group received routine care, including health education, psychological care, risk factor control, medication and routine exercise education;the intervention group implemented a yoga-based exercise based on the control group. The incidence of adverse cardiac events after intervention was compared between the two groups. Before and after the intervention, the 6-min walk test (6MWT), the Self-rating Anxiety Scale (SAS), and the Self-rating Depression Scale (SDS) were used to evaluate the two groups of patients. Results Within 6 months of interventional therapy, 11 patients in the control group developed angina pectoris, and 3 patients in the intervention group developed angina pectoris. The difference between the two groups was statistically significant (P<0.05). The differences of 6MWT distances between the two groups at 1st, 3rd, and 6th months after discharge were statistically significant (P< 0.05). The differences of SAS scores between the two groups at 1st, 3rd, and 6th months after discharge were statistically significant (P < 0.05). There were significant differences in SDS scores between the two groups at discharge, and 1, 3, and 6 months after discharge (P < 0.05). Conclusions Yoga-based exercise program can improve the exercise capacity of patients with acute myocardial infarction and relieve anxiety and depression.

Objective To investigate the correlation between serum vitamin D level and central precocious puberty(CPP)in girls.Methods A total of 103 girls(case group)with central precocious puberty from Ningbo Woman and Children's Hospital and 53 healthy girls(control group)from health check-ups in Ningbo Women and Children's Hospital were collected as subjects.The serum levels of 25-hydroxyvitamin D3[25(OH)D3]in the two groups were detected by chemiluminescence method.The weight and height of girls in the case group were measured.The serum levels of follicle-stimulating hormone(FSH)and its peak value,luteinizing hormone(LH)and its peak value,estradiol(E2),prolactin(PRL),human chorionic gonadotropin(HCG)and thyroid function were measured by radioimmunoassay.The peak value of LH/FSH was calculated.B ultrasound examination of uterine adnexa was completed to calculate uterine volume and bilateral ovarian volume.According to the results of serum 25-(OH)D3,girls in the case group were divided into normal vitamin D group and vitamin D deficiency group,and the differences of hormone levels,uterine and ovarian development between the two groups were compared.Results The serum level of 25-(OH)D3 in case group was lower than that in control group,and the vitamin D deficiency rate in case group was higher than that in control group,with statistical significance(P<0.05).The age of breast nodules in vitamin D deficiency group was lower than that in vitamin D normal group(P<0.05).There were no significant differences in body weight,height,body mass index(BMI),uterine volume and left ovarian volume between vitamin D normal group and vitamin D deficiency group(P>0.05),and the right ovarian volume in vitamin D deficiency group was significantly higher than that in vitamin D normal group(P<0.05).There were no significant differences in serum levels of FSH,LH,PRL,HCG,peak value of FSH and thyroid function between normal and deficient groups(P>0.05).The levels of E2,LH and LH/FSH in vitamin D deficiency group were significantly higher than those in vitamin D normal group(P<0.05);25-(OH)D3 was negatively correlated with LH/FSH peak(r=-0.197,P<0.05),but was not significantly correlated with thyroid function,FSH,LH,PRL,E2,HCG,FSH and LH peak(P>0.05).Conclusion Vitamin D deficiency is associated with central precocious puberty in girls.Vitamin D deficiency may lead to early onset of precocious puberty.Vitamin D deficiency may affect the hypothalamic-pituitary-gonadal axis function,resulting in changes in reproductive hormone indexes and consequent increase in ovarian volume in girls.
