Study on Network Pharmacology of the Mechanism of Lysimachia christinae in the Treatment of Cholecyst Related Disease / 中国药房

OBJECTIVE： To explore the mechanism of Lysimachia christinae in the treatment of cholecyst related diseases by network pharmacology. METHODS： The active ingredients of L. christinae were screened through TCMSP database with “Lipinski rule” and “Oral bioavailability ＞30％” rules， and their related targets were predicated correspondingly， then compound-target network were constructed by Cytoscape 3.2.1 software. Disease related targets were predicted by searching TTD database， OMIM database， PharmGKB database， DrugBank database and GAD database with “cholelithiasis” “gallstones” “cholecystitis” and “cholangitis” as keywords. Then， the network of disease-target was constructed and merged with active ingredient target to obtain therapeutic target. After pathway enrichment analysis of therapeutic target were performed by utilizing the DAVID database， molecular docking between target and active ingredient was also conducted in order to screen the main active ingredients of L. christinae. RESULTS： Twenty-seven active ingredients with good oral absorption and drug-like properties were screened from L. christinae. Thirty-three targets were attained after constructing and merging the network. Seven pathways， mainly related to cancer pathway and ABC transporter pathway were achieved. Top 4 active ingredients of L. christinae in the list of docking score were kaempferin， acacia， hesperetin and isorhamnetin， which acted on ABCC3， ABCB1， ABCC2， ABCB4 target. CONCLUSIONS： L. christinae treat cholecyst related diseases through ABC transporter pathway.

Photoselective vaporization of prostate for the treatment of very elderly patients with benign prostatic hyperplasia / 中华全科医师杂志

A total of 156 elderly patients (aged ≥ 70 years) with symptomatic bladder outlet obstruction as a result of benign prostatic hyperplasia (BPH) underwent trmsurethral photoselective vaporization (PVP). Pre- or post-operative urine flow rate, residual urine volume level, International Prostate Symptom Score (IPSS), and quality of life (QOL) score were recorded. Our data showed that maximum urine flow rate and residual urine volume were improved at 1, 12, 24, and 36 months following the treatment. There was statistically significant difference in IPSS and QOL when the intervention was considered (P < 0. 05). PVP might be a treatment of choice for high-risk elderly patients with obstructive BPH.
