Objective:To assess iodine nutritional status and the prevalence of thyroid dysfunction in Kunming, Yunnan Province, along with correlation and risk factors between thyroid dysfunction and urinary iodine levels.Methods:This cross-sectional study was conducted from January 2014 to July 2016 using a multi-stage, stratified cluster sampling method. A total of 2 650 residents of Kunming, Yunnan Province, who met the inclusion criteria were selected. Data on participants′ demographics, physical measurements, and laboratory tests were collected through questionnaire and clinical assessments which led to 1 463 subjects in the final analysis considering missing data. Statistical analysis were performed using SPSS 26.0, while R Studio was used to model the nonlinear relationship between urinary iodine levels and the risk of thyroid dysfunction.Results:(1) Among 2 650 subjects, 755(28.5%) were diagnosed with thyroid dysfunction, with incidence rates of clinical hyperthyroidism(0.83%), subclinical hyperthyroidism(0.38%), clinical hypothyroidism(1.36%), subclinical hypothyroidism(17.66%), and isolated thyroid antibody positive(13.85%). The median urinary iodine concentration was 177.49(123.59, 251.85) μg/L, indicating adequate iodine nutritional. (2)Among the 1 463 subjects analyzed, significant differences in urinary iodine were found between healthy individual group and abnormal TSH group or abnormal TSH group and thyroid antibody positive group( H=-83.437, P=0.003; H=107.489, P=0.003). Logistic regression revealed that rural residents had a lower risk of thyroid dysfunction than urban residents( OR=0.429, 95% CI 0.256-0.717, P=0.001). Risk of thyroid disease increased with age, and TSH, thyroid peroxidase antibody(TPOAb), thyroglobulin antibody(TgAb), and urinary iodine levels were identified as significant risk factors, with a U-shaped relationship between urinary iodine levels and thyroid dysfunction. Conclusions:The prevalence of thyroid dysfunction in Kunming is comparable to the national average. The relationship between urinary iodine concentration and thyroid dysfunction follows a U-shaped curve. Factors including region, age, TSH, TPOAb, TgAb, and urinary iodine concentration are associated with thyroid dysfunction.

OBJECTIVE To construct a double helix model for evaluating the job competency of licensed pharmacists in retail pharmacies， and to provide a reference for building a talented team of licensed pharmacists and promoting the high-quality development of pharmaceutical care. METHODS Based on the competency iceberg model and double helix structure theory， literature analysis and the Delphi method were adopted to explore the model indicators； questionnaires were designed to survey licensed pharmacists in retail pharmacies from Shandong Province. The exploratory factor analysis was used to correct the model indicators and establish a double helix model for evaluating the job competency of licensed pharmacists in retail pharmacies， which was examined by validation factor analysis. RESULTS The recovery rate of the questionnaires in the two rounds of expert consultation was greater than 90%， the expert authority coefficients were both more than 0.86， and the overall Kendall’s W values were 0.288 and 0.510， respectively； after the correction of the exploratory factor analysis， the double helix model for evaluating the job competency of licensed pharmacists in retail pharmacies was established， which contained 4 first-level indexes such as occupational literacy， occupational knowledge， occupational competency and internal motivation， and 23 second-level indexes. The model contained occupational knowledge and occupational competency in the explicit competency chain， occupational literacy and internal motivation in the implicit competency chain， and policy support， incentive mechanism， education and training as the hydrogen bonds connecting the two main chains. The validation factor analysis showed that the model’s goodness of fit index， comparative fit index， and normed fit index all exceeded 0.9； the reliability of the combination of the four first-level indexes ranged from 0.89 to 0.95； the average variance extracted ranged from 0.58 to 0.75， and Cronbach’s α coefficients for both the overall model and the first-level indicators were all greater than 0.84. CONCLUSIONS The constructed double helix model for evaluating the job competency of licensed pharmacists in retail pharmacies is scientific， reasonable and practical.

Background: Subclinical hypothyroidism (SCH) is the most common thyroid dysfunction, and its relationship with blood pressure (BP) has been controversial. The aim of the study was to analyze the association between SCH and newly-diagnosed hypertension. Methods: Based on data from the Thyroid disease, Iodine nutrition and Diabetes Epidemiology (TIDE) study, 49,433 euthyroid individuals and 7,719 SCH patients aged ≥18 years were enrolled. Patients with a history of hypertension or thyroid disease were excluded. SCH was determined by manufacturer reference range. Overall hypertension and stage 1 and 2 hypertension were diagnosed according to the guidelines issued by the American College of Cardiology/American Heart Association in 2017. Results: The prevalence of overall hypertension (48.7%), including stage 1 (28.9%) and 2 (19.8%) hypertension, increased significantly in SCH patients compared with euthyroid subjects. With elevated serum thyroid stimulating hormone (TSH) level, the hypertension prevalence also increased significantly from the euthyroid to different SCH subgroups, which was more profound in females or subjects aged <65 years. The age- and sex-specific regression analysis further demonstrated the same trends in the general population and in the 1:1 propensity matched population. Similarly, several BP components (i.e., systolic, diastolic, and mean arterial BP) were positively associated with TSH elevation, and regression analysis also confirmed that all BP components were closely related with SCH in female subjects aged <65 years. Conclusion The prevalence of hypertension increases for patients with SCH. SCH tends to be associated with hypertension and BP components in females younger than 65 years.

Objective: The aim of this study was to compare the efficacy and safety of metformin/thiazolidinediones (TZDs) / glucagon-like peptide 1 (GLP-1) analogs (triple therapy) with conventional glucose-lowering therapy(conventional therapy) for patients with type 2 diabetes and metabolic syndrome. Methods: A prospective randomized-controlled 26-week study was carried out. A total of 82 patients with type 2 diabetes and metabolic syndrome were randomized to receive either triple therapy protocal or just conventional therapy, altogether with 41 cases in each group. Results: HbA_1C value was significantly reduced in triple therapy group versus the conventional therapy group [(2.23±1.75)% vs (1.48±1.59)%, P<0.05]. Values of body mass index, waist circumference, and visceral fat area were significantly reduced in triple therapy group as compared to those of conventional therapy group [(2.50±1.81 vs 0.92±1.82)kg/m², (6.75±4.92 vs 1.66±3.25)cm, (24.10±19.10 vs 10.02±20.10)cm², all P<0.01, respectively]. Control rates of HbA_1C and fasting plasma glucose for triple therapy were higher than those for conventional therapy (both P<0.05). No hypoglycemia occurred in triple therapy group. Subjects receiving triple therapy experienced more frequent gastrointestinal side effects than those in conventional therapy group (18.87% vs 3.92%, P<0.05). The most common side event was mild nausea (90%). Conclusion Combination therapy with metformin/TZDs/GLP-1 analogs had statistically significant advantages in the control of body weight, waist circumference, and visceral fat area in addition to the control of blood glucose over conventional glucose-lowering therapy in our patient cohort, it seems to be an optimized therapeutic regimen for patients with type 2 diabete and metabolic syndrome.

Objective To explore the clinical significance of colonoscopy follow-up in Chinese Lynch syndrome mismatch repair (MMR) gene mutation carriers.Methods The results of colonoscopy follow-up was analyzed in 194 MMR gene mutation carriers of 50 Lynch syndrome families.The follow-up period was from April 2001 to November 2016.The detection rates of advanced adenomas and colorectal cancers,five-year survival rate and ten year survival rate were compared between 123 patients of regular follow-up group (colonoscopy interval less than two years) and 71 patients of irregular follow-up group (time colonoscopy interval more than two years).T test,chi-square test and Kaplan-Meier method were performed for statistically analysis.Results The incidence of colorectal cancer of irregular follow up group was significantly higher than that of regular follow-up group (57.7％,41/71 vs 22.8％,28/123);and the difference was statistically significant (x2 =24.00,P＜0.01).The average age at diagnosis for colorectal cancer in irregular follow up group was younger than that of regular follow up group ((45.3 ± 1.9) years vs (48.7±1.8) years);and the difference was statistically significant (t=4.10,P＜0.01).In regular follow-up group,28.6％ (8/28) advanced-stage colorectal cancer (TNM Ⅲ or Ⅳ) was found,while in irregular follow up group,73.2 ％ (30/41) advanced-stage colorectal cancer was found,and there was statistically significant difference in pathological stage between two groups (x2 =4.90,P =0.032).The five year and ten-year survival rates of regular follow-up group were 96.2 ％ and 85.1 ％,respectively,which were both higher than those of irregular follow-up group (46.3 ％ and 28.7 ％);and the differences were statistically significant (x2 =13.20 and 14.80,both P＜0.05).The incidence of advanced adenomas of irregular follow up group was significantly higher than that of regular follow-up group (49.3％,35/71 vs 18.7％,23/123);and the difference was statistically significant (x2 =20.10,P＜0.05).The detection rate of advanced adenomas of MMR gene mutation carriers was higher than those without MMR mutation gene (85.4％,35/41 vs 14.6％,6/41);and the difference was statistically significant (x2 =5.20,P＜ 0.05).Conclusion Regular colonoscopy surveillance may decrease the incidence and mortality of colorectal cancer in MMR mutation carriers of Lynch syndrome families,and increase five-year and tenyear survival rates.

Objective To investigate the effects of glutathione protected gold nanoclusters (GSH-Au NCs) on HeLa cytotoxity.Methods Fluorescence intensity were measured on GSH-Au NCs containing medium treated cells using fluorescence spectrophotometer at different time points.GSH-Au NCs uptake by HeLa cells at 1,2,6,12 and 24 h were investigated through fluorescent spectrophotometer.In vivo tumor uptake was also investigated on BALB/c tumor-bearing mice through inductively coupled plasma mass spectrometry (ICP-MS) at 24 h after intraperitoneal injection of 0.2 ml GSH-Au NCs (3 mmol/L) and distilled water (control group) respectively.The cytotoxicity of GSH-Au NCs at different doses (0.003-0.3 mmol/L) was tested at 24 and 48 h using MTT assay after interaction with HeLa cells.Results The uptake efficiency of GSH-Au NCs by HeLa cells kept increasing and reached maximum of 73.13％ at 24 h.The results of tumor-bearing mice indicated that the tumor tissue had higher uptake efficiency after 24 h (320±15) ng/g than that of control group (intraperitoneal injection of distilled water),and the difference was stastically significant (P＜0.05).HeLa cells were treated with different concentrations of GSH-Au NCs for 24 h,and GSHAu NCs had a slight effect on cell viability.With the increase of GSH-Au NCs dose,the inhibition effects on growth of HeLa cells enhanced.The cell activity of HeLa cells treated with 0.3 mmol/L GSH-Au NCs for 24 h reduced to 86％compared with that of control group (the concentration of GSH-Au NCs was 0) (P＜0.05),while there was no significant difference between the survival rate of different concentrations of GSH-Au NCs group and the control group for 48 h.Conclusions GSH-Au NCs have neglectable cytotoxity on HeLa cells even though both in vitro and in vivo uptake are high.GSH-Au NCs are suitable for biomedical application such as imaging,drug loading and targeted drug delivery.

Objective To investigate the relationship between thyroid hormone and uric acid (UA) and body mass index (BMI) in patients with type Ⅱ diabetes and normal thyroid function.Methods Total of 313 patients with type Ⅱ diabetes and normal thyroid function were selected.BMI,fasting blood glucose (FBG),the metabolism of blood lipid,thyroid hormones and UA indicators were examined and the correlations of thyroid hormone,BMI and UA were analyzed.Results (1) The patients were divided into two groups according to gender,and FT3,FT4,and UA of male were found to be significantly higher than those in female (P＜0.01).TSH,SBP,HDL-C in female were significantly higher than those in male (P＜0.01);(2) The patients were divided into three groups according to BMI Level.Thyroid-stimulating hormone (TSH),three iodine armour gland original glycine (TT3),free three iodine thyroid glycine (FT3),UA,and FBG in overweight and obesity groups were found to be higher than those in normal weight group (P ＜ 0.05);(3) The patients were divided into two groups according to the TSH level.Serum uric acid,TT3,FT3,fasting insulin in the group with TSH above 2.5 uIU/L were found to be higher than those in the group with TSH under 2.5 uIU/L (P ＜ 0.05);(4) Patients were divided into two groups according to the UA level.TSH,FT3 in male with high uric acid were found to be higher than those in male with normal uric acid (P ＜ 0.05);TSH was in female with high uric acid was found to be higher than that in female with normal uric acid (P ＜ 0.05).Conclusion Thyroid hormone in patients with type Ⅱ diabetes can be used to assess the body weight and uric acid,which is of great clinical importance.

Cancer has become the second largest life-threatening disease nowadays.Radiotherapy and chemotherapy are still important treatments for cancer.However, they tend to produce a lot of serious adverse effects including bone damage and bone marrow fat, etc.Based on recent research, the research progress on canonical Wnt pathway and its impact on stromal stem cells differentiation into osteoblasts and adipocytes are reviewed.Radiochemotherapy-induced bone damage and bone marrow fat is closely related to canonical Wnt pathway.In experimental assay and clinical application, Wnt pathway antagonists, such as Dickkopf-1 (DKK-1), sclerostin, and secreted frizzled-related protein 1 (sFRP-1) are used to relieve bone damage.Wnt pathway is expected to become a potential target for the therapy of bone damage and bone marrow fat induced by raidochemotherapy.
