ObjectiveTo determine the serum vitamin D levels of patients with primary hypertension to provide a basis for prevention and control of the hypertension in Kashgar prefecture.Methods The clinical data of 200 patients with hypertension in Kashgar prefecture admitted to the Second People's Hospital from January 2014 to December 2015 were retrospectively analyzed. According to risk factors, the 200 patients with primary hypertension were divided into three groups: 60 patients were selected as low risk group (hypertension 1 grade and no risk factors), 64 patients were arranged into an intermediate risk group (hypertension 2 grade or hypertension 1 grade accompanied by 1-2 risk factors) and 76 patients were assigned in a high risk group (hypertension 3 grade or hypertension 1-2 grade accompanied by ≥3 risk factors or hypertension of any grade accompanied by 1 target organ damage or 1 kind of clinical disease). In the same period, 66 healthy subjects having taken physical systemic medical examination with normal blood pressure in this hospital were grouped into a healthy control group. The levels of blood pressure and vitamin D in serum were measured, and the correlations between vitamin D and systolic blood pressure (SBP), diastolic blood pressure (DBP) were analyzed by pearson correlation analysis in the four groups.Results The SBP and DBP were significantly higher in low, intermediate and high risk group than those in healthy control group [SBP (mmHg, 1 mmHg = 0.133 kPa): 142±6, 161±5, 173±12 vs. 112±12, DBP (mmHg): 89±7, 101±4, 103±11 vs. 74±8], and their levels of vitamin D were lower in low, intermediate, high risk group than the level in healthy control group (μg/L: 24±6, 26±5, 20±4 vs. 30±7, allP < 0.05). Correlation analysis showed that the level of vitamin D was negatively correlated with SBP, DBP (r value was -0.373, -0.324, allP < 0.01).Conclusions The serum level of vitamin D is decreased in Uighur patients with blood hypertension in Kashgar prefecture, especially in the patients with high risk factors, the descent of the serum level is more significant. It is suggested to appropriately use vitamin D supplement to prevent blood hypertension.

OBJECTIVE: To explore the diagnostic value of the proposed thyroid imaging reporting and data system (TI-RADS) classification in thyroid nodules, and to investigate interobserver variability among different observers using TI-RADS classification for ultrasound. METHOD: We reviewed 667 thyroid nodules conventional ultrasound image data from 532 patients who were confirmed by Pathological diagnosis. Those ultrasound images were reviewed by 4 experienced sonographers who can independently assessed the sonographic characteristics and analyzed according to the TI-RADS classification. It is to assess the diagnostic sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of the TI-RADS classification. The multirater kappa statistics were used to assess the interobserver agreement among different observers. RESULT: The overall sensitivity, specificity, negative predictive value (NPV) and Accuracy were 94%, 79%, 97% and 81%, respectively. Positive predictive values (PPVs) for categories 4 and 5 were 55% and 92%. There was substantial interobserver agreement for categories 3, 4B and 5 (Kappa = 0.62, 95% CI, 0.58-0.65), and was moderate agreement for category 4A (Kappa = 0.57) and 4B(Kappa = 0.60). CONCLUSION The diagnostic criteria of TI-RADS for differentiating between benign and malignant thyroid nodules have a high diagnostic value. There was substantial interobserver agreement in different experienced sonographers. The TI-RADS diagnostic criteria have a high diagnostic value and has great practical value in making a proper and further treatment plan.

More than 50％ microRNAs (miRNAs) are located in tumor-associated genome of amplification region or fragile site,which may also act as oncogenes or tumor suppressor gene (TSG).Recently,researches show that the expression of miR-449 is lower in human gastric,lung and ovarian cancer,and may act as TSG.The abnormal expression of miR-449 plays a pivotal role in carcinogenesis and progression,and elucidating its function and regulatory,mechanism can provide valuable diagnostic,prognostic biomarker for cancer management.

Bone remains the predominant site of metastasis in advanced breast cancer. Bone metastases dramatically decrease the quality of life. Moreover, pathologic fractures and other skeletal-related events (SREs) caused by bone metastases could result in higher mortality risk in patients with breast cancer. Palliative radiotherapy is a crucial element in bone metastases treatment. The present review discusses the emerging evidence in bone metastases of breast cancer, focusing on optimized radiotherapy strategies and multidisciplinary management.
