[Epidemiological and clinicopathological characteristics of prostate cancer in Hunan].

Objective: To investigate the epidemiological and clinicopathological characteristics of PCa and provide some strategies for the clinical prevention and treatment of the malignancy.

Methods: This study included 1 594 cases of pathologically diagnosed PCa after radical prostatectomy in Xiangya Hospital of Central South University from January 1, 2010 to December 31, 2020. We collected the basic information about the patients, their main complaints and clinicopathological results, and analyzed the epidemiological and clinicopathological data.

[Xiongcan Yishen Prescription up-regulates the expressions of cholesterol transport proteins, steroidogenic enzymes and SF-1 in the Leydig cells of rats with late-onset hypogonadism].

Objective: To investigate the effects of Xiongcan Yishen Prescription (XYP) on the expressions of cholesterol transport proteins, steroidogenic enzymes and steroidogenic factor-1 (SF-1) in the Leydig cells of the rats with late-onset hypogonadism (LOH).

Methods: Twenty-five 18-month-old male SD rats were randomly divided into five groups of equal number, LOH model control, testosterone propionate (TP) and low-, medium- and high-dose XYP, and another 5 two-month-old male SD rats included as normal controls. After modeling, the animals in the TP group were treated by intramuscular injection of TP at 5.

CTHRC1 and PD‑1/PD‑L1 expression predicts tumor recurrence in prostate cancer.

Collagen triple helix repeat containing 1 (CTHRC1) is a gene that has been associated with tumor progression in human prostate cancer (PC). The tumor immune microenvironment has been linked with disease outcome in PC. In the present study, the correlation between CTHRC1 with PC recurrence and the tumor immunological microenvironment was investigated.

[Combination of musk and olibanum promotes proliferation of prostate stem cells in mice: An experimental study].

Objective: To study the effects of muskolibanum combination on the proliferation and differentiation of prostate stem cells.

Methods: We cultured prostate epithelial cells and urogenital sinus mesenchymal (UGSM) cells from 7－10 d old C57BL/6 mice and 16－18 d old pregnant C57BL/6 mice, transplanted the mixed suspension of the two types of cells under the kidney envelope of SCIDCB.17 male mice, and harvested the transplants 30 days later.

[Effects of the combination of musk and olibanum on the expressions of tight junction proteins in the prostate epithelial cells of rats].

Objective: To investigate the effects of the combination of musk and olibanum on the tight junction protein expressions in prostatic epithelial cells of normal and chronic prostatitis (CP) rats.

Methods: Eighty male SD rats were randomly divided into 8 groups of equal number: normal control, normal musk, normal olibanum, normal musk + olibanum, CP model control, CP model musk, CP model olibanum, and CP model musk + olibanum. At 60 days after modeling, the rats in the control, musk, olibanum, and musk + olibanum groups were treated intragastrically with normal saline, musk (0.

[Mechanisms of musk and olibanum regulating inflammatory cascade reaction triggered by chemotactic and activated monocytes].

Objective: To study the effects of drug plasma of musk and olibanum (DP-M&O) on the release of inflammatory cytokines from monocytes and the expressions of the proteins associated with inflammation of prostatic or endothelial cells induced by prostate antigen (PAg) stimulation.

Methods: We prepared DP-M&O using SD rats and monocytes and PAgs using BALB/c mice. We pre-treated the monocytes with DP-M&O at the gradient concentrations of 0, 2.
