Retinal Neurovascular Impairment in Patients with Essential Hypertension: An Optical Coherence Tomography Angiography Study.

Purpose: To investigate retinal neurovascular structural changes in patients with essential hypertension.

Methods: This observational cross-sectional study consisted of 199 right eyes from 169 nondiabetic essential hypertensive patients, divided into groups as follows: group A, 113 patients with hypertensive retinopathy (HTNR); group B, 56 patients without HTNR; and a control group of 30 healthy subjects. Peripapillary retinal nerve fiber layer (RNFL), radial peripapillary segmented (RPC), ganglion cell-inner plexiform layer (GC-IPL), and superficial (SVP) and deep (DVP) vascular plexus density at the macula (6 × 6 mm2) were measured by optical coherence tomography angiography (OCTA).

[Study on the content of curcumin by HPLC and the anti-tumor effect in vivo from different processed products of Curuma kwangsiensis].

Objective: To determine curcumin content by HPLC and observe the antitumor effects in vivo from different processed products of Curuma kwangsiensis.

Methods: We determined the content of curcumin by HPLC from different processed products of Curuma kwangsiensis and studied the anti-tumor effects in vivo by establishing S180 transplanted tumors model in mice.

Results: The content of curcumin in different processed products of Curuma kwangsiensis as follows: primitive > vinegar-fried > vinegar-cooked.

[Effects of Calotes versicolor on adenohypophysis androgen receptor level in mature castrated male rats].

Objective: To study the effects of C. versicolor petroleum ether extracts (CVPE) on the adenohypophysis androgen receptor level in mature castrated male rats.

Method: All the rats in experiment were anesthetized for bilateral testicular and epididymis removal under sterile condition.

[Studies of Calotes versicolor on the sexual function amelioration mechanism by hypothalamus inhibition in immature male rats].

Objective: To study the amelioration mechanism of Calotes versicolor petroleum ether extracts (CVPEE) on hypothalamus inhibition sexual function induced by morphine in immature male rats.

Methods: The hypothalamus inhibition induced by morphine in immature male rats was used as model of the testis reproductive functional disturbance. The rats was given CVPEE for 21 days.

[Effects of osthol on androgen level and nitric oxide synthase activity in castrate rats].

Objective: To investigate the effects of osthol on androgen level and nitric oxide synthase (NOS) activity in castrate rats.

Methods: Immature castrate male rats were treated with osthol daily for 20 d. The levels of testosterone(T), luteinizing hormone (LH) and follicle stimulating hormone (FSH) in serum and the activity of NOS, the nitric monoxide (NO) level in penis tissue were determined.
