Association of cardiometabolic index and lipid accumulation product with hypertension prevalence in adults in Pingshan District, Shenzhen / 公共卫生与预防医学

Objective To explore the association of (cardiometabolic index , CMI ) and ( lipid accumulation product , LAP ) with the prevalence of hypertension in adults in Pingshan District, Shenzhen, and to evaluate the predictive value of CMI and LAP for the prevalence of hypertension. Methods A cross-sectional survey was conducted, in which 1000 permanent residents aged 18-69 years in Pingshan District, Shenzhen were randomly selected as survey subjects. The data were collected using questionnaires, physical measurements and blood tests, and the relationship between CMI, LAP and hypertension prevalence was analyzed using logistic regression models. Results A total of 987 subjects were included in the analysis, including 471 (47.72%) males and 516 (52.28%) females, with an average age of 40.9 ± 11.1 years. Subjects of different genders were divided into groups Q1 to Q4 according to quartiles of CMI and LAP, and the prevalence of hypertension increased with increasing levels of CMI and LAP in both men and women (P for trend < 0.001). Logistic regression analysis revealed that after adjusting for variables such as age and occupation, the OR for hypertension was 1.251 (1.025-1.526) and 1.685 (1.001-2.836) for men and women, respectively, for each standard deviation increase in CMI; the OR for hypertension was 3.519 (1.343-9.222) for men in the Q4 group, compared to the CMI subgroup Q1. For each standard deviation increase in LAP, the ORs for hypertension were 1.355 (1.089-1.686) and 1.825 (1.023-3.254) for men and women, respectively; compared to LAP subgroup Q1, the ORs for hypertension in the male Q3 and Q4 groups were 2.554 (1.103-5.909) and 5.322 (2.393-11.834), while the OR for hypertension in the female Q4 group was 2.906 (1.096-7.703). ROC analysis revealed that the area under the curve (AUC) for CMI, LAP, and BMI was 0.671, 0.704, and 0.702 for males, and 0.660, 0.722, and 0.697 for females, respectively. The AUC for LAP was greater than that for CMI for different genders (P < 0.01). Conclusion The greater the CMI and LAP values in adults in Pingshan District, Shenzhen , the higher the prevalence of hypertension. CMI and LAP have certain values in predicting the prevalence of hypertension.

LncRNA-TDRG1 facilitates the malignant biological behavior of cervical cancer cells / 西安交通大学学报(医学版)

【Objective】 To investigate the molecular mechanism of long non-coding RNA (lncRNA) TDRG1 in facilitating the malignant progression and poor prognosis of patients with cervical cancer. 【Methods】 Cervical cancer cell lines and normal cervical cell Ect1/E6E7 were collected. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression of TDRG1. Cervical cancer cell lines were transfected with TDRG1-siRNA, and the proliferation of cancer cells was detected by CCK-8 method and cell plate cloning experiment. The invasion and migration of cancer cells were measured by Transwell experiment. The apoptosis of cancer cells was examined by flow cytometry, and the expressions of relevant proteins were tested by Western blot. 【Results】 Compared with Ect1/E6E7, cervical cancer cell lines showed relatively increased expression of TDRG1. Downregulation of TDRG1 expression inhibited the proliferation and colony formation (162±21 vs. 411±33, P<0.05), as well as the invasion and migration (invasion: 86±13 vs. 315±38, P<0.01; migration: 177±22 vs. 406±41, P<0.01) of Hela cells. Meanwhile, the apoptosis of Hela cells increased [(28±1.5)% vs. (16±1.2)%, P<0.05] and the expression of Bcl-2 protein reduced. In addition, TDRG1 knockdown also decreased the activity of autophagy in Hela cells. 【Conclusion】 TDRG1 facilitates the malignant biological progression of cervical cancer by inhibiting the apoptosis and providing a protective autophagy in cervical cells.

Inhibitory action of docetaxel on the proliferation of HeLa and SiHa cells / 药物分析学报

Objective To study the inhibitory action of docetaxel (DOC) on the proliferation of HeLa and SiHa cells. Methods Cell morphological changes were observed with inverted phase contrast microscope. MTT was adopted to test and calculate the cell inhibition ratio. Flow cytometry was used to detect cell cycle. Results DOC had an obvious concentration-dependent inhibitory effect on the proliferation of both HeLa and SiHa cells. The inhibition ratio of DOC on SiHa was significantly higher than that on HeLa (P<0.05). DOC blocked HeLa at G2/M phase. Under the effect of DOC, the cell cycle of SiHa was not changed much. Conclusion DOC has an obvious inhibitory action on both HeLa and SiHa cells, which shows a promising prospect of DOC in clinical treatment of cervical cancer.

Comparative study on ghrelin level change and its related factors in hypertensive elders with psychological distress / 药物分析学报

Objective To investigate the change of plasma ghrelin level and explore the related factors of ghrelin alteration in elderly hypertensive patients with psychological distress. Methods A total of 300 elders, who were screened with Hamilton Anxiety Scale (HAMA), Hamilton Rating Scale for Depression (HAMD), and the Symptom Checklist-90 (SCL-90) for psychological stress and somato-psychological manifestations respectively, were divided into hypertension group (n=148) and non-hypertension group (n=152). Their blood samples were collected to measure the plasma level of ghrelin and total cortisol on the same day. Results The incidences of anxiety and depression were 27.7% and 11.7%, respectively, in all the enrolled elders. However, the rates of psychological distress, particularly anxiety, were significantly higher in the hypertensive elders than in the non-hypertensive ones (43.2% vs. 12.5%). Anxiety was positively related to the cortisol level but negatively related to the plasma ghrelin level, and the latter two were negatively correlated with each other. Conclusion Chronic increase of plasma cortisol induced by long-term anxiety can lead to the reduction of ghrelin level, which then adversely affects blood pressure in elders with psychological distress. Therefore, ghrelin might be a selective antihypertensive medicine for hypertensive elders with anxiety.
