[A new 9,19-cycloartane glycoside from Asplenium ruprechtii].

Chemical constituents of water extracts of Asplenium ruprechtii were investigated. Five compounds were isolated by silica gel, Sephadex LH-20 gel column chromatographies and preparative HPLC, and their structures were identified by various spectral analyses as aspleniumside G(1), trans-p-coumaric acid(2), trans-p-coumaric acid 4-O-β-D-glucoside(3), cis-p-coumaric acid 4-O-β-D-glucoside(4), and(E)-ferulic acid-4-O-β-D-glucoside(5). Among them, compound 1 is a new 9,19-cycloartane glycoside.

[Comparison of transurethral detaching resection and plasmakinetic transurethral resection of the prostate for benign prostatic hyperplasia].

Objective: To compare the clinical effects of transurethral detaching resection (TUDRP) and plasmakinetic transurethral resection of the prostate (PKRP) for benign prostatic hyperplasia (BPH).

Methods: We collected by the single blind method the clinical data of 81 cases of BPH treated by PKRP (n=41) and TUDRP (n=40), and compared the two groups of patients in their age, preoperative prostate volume, weight of the resected gland, operation time, intraoperative bleeding, time of postoperative Foley's catheter retention, and pre- and post-operative IPSS.

Results: The post-operative IPSS was significantly higher in the PKRP than in the TUDRP group (9.

[Discussion on pharmacological mechanism of laosun kangfu tablets].

Objective: to study pharmacological mechanism of Laosun Kangfu tablet.

Method: Blood-activating and stasis-removing was tested by establishing cute cold pathogens induced blood stasis rat model and microcirculation disturbance state rat model by means of dripping adrenine on the mensentery. The resisting oxidation was tested by establishing the freely falling body damages models.
