Objective To find out the relationship between ambulatory pulse pressure (24 h PP) and left ventricular hypertrophy (LVH) and the enlarged diameter of aortic root (AOD) in aged pati ents with essential hypertension.Methods 118 aged patients with essential hypertension we r e examined by ambulatory blood pressure (ABP) and echocardiography,the different index of ABP and left ventricular mass index (LVMI) and AOD were measured.The p atients were divided into group A (24 h PP≥60 mmHg) and group B (24 h PP

Background: Androgenetic alopecia (AGA) leads to thinning of scalp hair and affects 60%~70% of the adult population worldwide. Developing more effective treatments and studying its mechanism are of great significance. Previous clinical studies have revealed that hair growth is stimulated by 650-nm red light. Objective: This study aimed to explore the effect and mechanism of 650-nm red light on the treatment of AGA by using ex vivo hair follicle culture. Methods: Human hair follicles were obtained from hair transplant patients with AGA. Hair follicles were cultured in Williams E medium and treated with or without 650-nm red light.Real-time RT-PCR and immunofluorescence staining were used to detect the expression level of genes and proteins in hair follicles, respectively. RNA-sequencing analysis was carried out to reveal the distinct gene signatures upon 650 nm treatment. Results: Low-level 650 nm red light promoted the proliferation of human hair follicles in the experimental cultured-tissue model. Consistently, 650 nm red light significantly delayed the transition of hair cycle from anagen to catagen in vitro. RNA-seq analysis and gene clustering for the differentially expressed genes suggests that leukocyte transendothelial migration, metabolism, adherens junction and other biological process maybe involved in stimulation of hair follicles by 650-nm red light treatment. Conclusion The effect of 650-nm red light on ex vivo hair follicles and the transcriptome set which implicates the role of red light in promoting hair growth and reversing of miniaturization process of AGA were identified.

Objective To investigate the correlation between tumor-associated macrophages (TAMs) and the development of high risk human papilloma virus (hr-HPV)-related cervical cancer. Methods A total of 112 cases of cervical tissue were collected, including 16 normal cervical tissues, 55 cervical intraepithelial neoplasia (CIN) tissues and 41 squamous cervical cancer (SCC) tissues. The expression of CD163+ macrophages in the cervical tissues was detected by immunohistochemical method, and the results were analyzed in relation with the clinical data of the patients. Results Immunohistochemical analysis showed that the cell density of CD163+macrophages increased progressively with the increase in the tissue malignancy, in the order of normal cervical tissue, CIN I, CIN II-III, and SCC. Correlation analysis revealed a positive relationship between CD163 + macrophage density and tissue malignancy (P=0.000). The density of CD163 + macrophages was significantly upregulated in HR-HPV-positive SCC tissue (P<0.05). CD163+ macrophages were positively correlated with cervical lymph node metastasis (P=0.005) and FIGO stage (P=0.004) of SCC. Conclusion The expression of CD163+macrophages is positively correlated with malignant transformation of cervical tissues, and hr-HPV infection is significantly correlated with CD163 expression level in the macrophages. CD163+ macrophages can be used as predictors of the occurrence and progression of cervical cancer caused by hr-HPV infection.
