ABSTRACT
Objective:To assess the prevalences of hypertension, rates of medication recommendations and failure rates of blood pressure(BP)control in Chinese elderly patients(≥65 years old).Methods:We used data from the 2011 China Health and Nutrition Survey(CHNS). A total of 2, 391 Chinese adults aged≥65 years with complete information comprising BP measurements repeated three times and antihypertensive medication use were included for analysis.Results:The mean age of subjects was 72.6±6.2 years, and females accounted for 53.1%.The numbers of patients with hypertension were 1784(74.6%)and 1221(51.1%)according to the definitions from 2017 ACC/AHA guideline and the 2010 Chinese guideline, respectively.There was a significant difference in the prevalence of hypertension in the subgroup with a cardiovascular disease(CVD)history according to the definitions from the two guidelines( χ2=23.70, P<0.01). The BP thresholds for drug therapy recommendations were the same as those set in the diagnostic criteria of hypertension based on the two guidelines.Therefore, the rates for medication recommendations were 74.6% and 51.1%, respectively.The numbers of patients with BP above the target levels were 622(88.2%)and 346(49.1%), respectively, according to the definitions from the two guidelines.There was no significant difference in failure rate of BP control due to age( χ2=5.36, P>0.05), gender( χ2=0.12, P>0.05)or a CVD history( χ2=0.07, P>0.05)according to analyses using the definitions from the two guidelines. Conclusions:Compared with the 2010 Chinese hypertension guideline, the prevalence of hypertension and rate of medication recommendations are higher in the Chinese elderly population when the 2017 ACC/AHA hypertension guideline is used.Hypertension management and antihypertensive drug treatment should be reinforced to improve the control rate of hypertension.
ABSTRACT
Objective:To investigate the relationship between BRAF V600E gene mutation and ultrasonography manifestations as well as the lesion invasiveness in thyroid cancer.Methods:A total of 153 patients pathologically diagnosed as thyroid cancer after surgery who underwent thyroidectomy in Shanxi Provincial Cancer Hospital from January 2018 to October 2019 were selected, including 146 cases of papillary thyroid carcinoma. Ultrasonography was performed before operation. Paraffin embedded tissue after operation was used to detect BRAF V600E gene mutation. According to the results of BRAF V600E gene detection, patients were divided into mutation group and non-mutation group. The ultrasonic characteristics of the two groups were compared. The relationship of BRAF V600E gene mutation with ultrasonic characteristics, clinicopathological characteristics as well as cervical lymph node metastasis was analyzed by using logistic regression.Results:There were 130 cases (85.0%) of BRAF V600E gene mutation and 23 cases of BRAF V600E gene non-mutation in 153 patients with thyroid cancer. Among 146 cases with papillary thyroid carcinoma, there were 128 cases (87.7%) of BRAF V600E gene mutation. The percentage of patients with the unclear boundary between thyroid lesions and capsule in BRAF V600E gene mutation group was higher than that of patients in non-mutation group, and the difference was statistically significant [46.9% (60/128) vs. 11.1% (2/18), χ 2 = 8.261, P = 0.004]. There were no significant differences in age, gender, nodule long diameter, aspect ratio, nodal location, internal calcification, internal echo, echo uniformity, cystic solid, nodal shape, boundary clarity, blood flow signal, the number of tumor site, lymph node metastasis and nodular goiter between BRAF gene mutation group and non-mutation group (all P > 0.05). The results of logistic regression analysis showed that only the boundary clarity between thyroid lesions and capsule was an independent influencing factor of BRAF V600E gene mutation ( OR = 14.400, 95% CI 1.847-112.246, P = 0.011), tumor lesion size was an independent influencing factor of cervical lymph node metastasis in papillary thyroid carcinoma ( OR = 2.714, 95% CI 1.335-5.517, P = 0.006). Conclusions:In papillary thyroid carcinoma, BRAF V600E gene mutation is related with lesion and the unclear boundary between the tumor and capsule, but not related with lymph node metastasis. The size of the tumor lesion is associated with lymph node metastasis.

ABSTRACT
Objective To discuss the contrast-enhanced ultrasonography diagnostic value of the liver low-density focus on contrast-enhanced CT. Methods The contrast-enhanced ultrasonography results of 47 cases of the liver low-density focus on contrast-enhanced CT. were retrospectively analyzed. Results The pathological diagnosis in 47 focuses was metastatic carcinoma 20 cases, inflammatory pseudotumour 9 cases,hepatic hemangioma 6 cases, primary liver carcinoma 4 cases, cyst 2 cases, abscess 2 cases, tuberculosis 2 cases, FNH (focal liver nodular hyperplasia) 1 case, local adipose tissue infiltration of liver 1 case. 45 cases of contrast-enhanced ultrasonography diagnosis was consistent with pathological or clinical diagnosis. Cysts and inflammatory pseudotumour had not ultrasound contrast enhancement in the entire phase, but the crossed blood vessels was observed in inflammatory pseudotumour. The local adipose infiltration of liver had synchronous ultrasound contrast enhancement accompanied with liver tissue enhancement. 80% (12/15) of liver metastases of lack of blood supply showed fast contrast enhancement around the tumour edge and homogeneous and light contrast enhancement in the tumour center. 80 % (4/5) of liver metastases of rich of blood supply showed heavy and rapid contrast enhancement in the whole tumour. The enhancement degree in bscess and tuberculosis in the ultrasound contrast enhancement was correlated with necrosis degree, which showed fast and uneven contrast enhancement, hepatic hemangioma showed gradually contrast enhancement from its edge to center, whose enhancement time lasted for longer time than that of metastatic tumour with a statistically difference. FNH showed a typical contrast enhancement pattern, fast enhancement and fast weakening from center to edge. Hepatic cell carcinoma showed fast enhancement and fast weakening in the whole tumour. Conclusion Contrast-enhanced ultrasonography have diagnostic value of CT liver focus of low-density, which is helpful for the differential diagnosis of such focus.
ABSTRACT
Objective To compare the value of intrarectal filling with water and filling in rubber sheath with water in endoluminal uhrasonography for preoperative staging of rectal tumors. Methods 215 cases of rectal tumors were divided into two groups. 120 cases using the method of filling in rubber sheath with water and 95 cases using intrarectal filling with water were diagnosed with uhrasonography. The results were compared with corresponding pathologic results for the judgment of their accuracy. Results The accuracy for the diagnosis of infiltration depth was 60.0 % in the first group and was 73.7 % in the second. The difference was statistically significant (P <0.05). The accuracy for diagnosis of metastases of perirectal lymph nodes was 82.5 % in the first group and was 80.0 % in the second. The difference has no statistical significance (P >0.50). Conclusion Intrarectai filling with water is better than filling in rubber sheath with water in the diagnosis of infiltration depth of rectal tumors, while there is no difference in the diagnosis of metastasis of perirectal lymph nodes.
ABSTRACT
Objective To evaluate the value of ultrasound in diagnosing ductal carcinoma in situ (DCIS). Methods The sonographic characteristics of 12 DCIS which were confirmed by pathology were analyzed retrospectively. Results The ultrasound image of DCIS could be divided into four types;the solid mass nodule, mammary dysplasia, mix mass nodule, the dilated duct type. Micro calcification had high incidence rate. Ultrasonic diagnosis accordance rate was 50.0 %. On molybdenum target mammograms, the tumor appeared as a cluster of calcified spots in 8 cases, and the accuracy rate of diagnosis of was 66.7 %.Conclusion There are no typical characters of DCIS in ultrasound image. However, some characteristics are suggestive and can help to differentiate them from the benign tumors, such as small nodule, irregular shape,obscure boundary, and microcalcification. When sonography combine with molybdenum target mammography,the accuracy rate of diagnosis will be improved.
