OBJECTIVETo observe the effect of Rg1-induced NSCs in treatment of neonatal rat model with hypoxiaischemia.

METHODThe neonatal rat model of HIE was established and assessed by using TTC staining and behavioral observation, then Rg1-induced NSCs was transplanted into the neonatal rat of HIE by lateral ventricle injection. Water maze test and somatosensory evoked potential were detected to observe brain function and the immunohistochemistry was done to assess growth and differentiation about transplanted NSCs a month after transplanted.

RESULTThe transplantation of Rg1-induced NSCs could significantly shorten incubation period, swimming distance, exploration time of target quadrants of water maze test and incubation period and amplitude of somatosensory evoked potentials. Additionally, the concentrated expression appeared in the hippocampus and grew around the ischemic injury area in transplantation group.

CONCLUSIONTransplantation of Rg1-induced NSCs play a better role in the treatment of neonatal HIE rats.

In order to investigate the chemical constituents of glycosides in Piper sintenense Hatusima, column chromatographic techniques such as silica gel, ODS, MCI GEL CHP20P, Sephadex LH-20, and semi-preparative high performance liquid chromatography were used to afford nine glycosides from the n-butanol part of the 95% ethanol extract of Piper sintenense Hatusima. Based on the physicochemical properties and NMR data, the above compounds were identified as (2S)-2-hydroxy-1-(4-hydroxy-3-methoxyphenyl)-1-propanone-2-O-β-D-glucopyranoside (1), 2-phenylethyl β-D-glucopyranoside (2), benzyl α-L-arabinopyranosyl-(1''→6')-β-D-glucopyranoside (3), benzyl β-D-xylopyanosyl-(1''→6')-β-D-glucopyranoside (4), phenethyl β-D-apiofuranosyl-(1''→ 2')-β-D-glucopyranoside(5), salidroside (6), phenethanol β-D-xylopyanosyl-(1''→6')-β-D-glucopyranoside (7), (Z)-hexenyl-O-α-L-arabinopyranosyl-(1''→6')-O-β-D-glucopyranoside (8), (Z)-hexenyl-O-β-D-xylopyanosyl-(1''→6')-O-β-D-glucopyranoside (9). Compound 1 was identified as a new compound, and compounds 3-9 were isolated from the genus Piper for the first time.

Objective To explore the efficacy and safety of"ditching and ridge removal"with 450 nm semiconductor blue laser in the treatment of large volume benign prostatic hyperplasia(BPH),in order to promote the clinical application of this method.Methods A retrospective study was conducted on 30 patients with large volume BPH treated with"ditching and ridge removal"with 450 nm semiconductor blue laser in Yingsheng Branch of Tai'an Central Hospital during Sep.and Dec.2023.The laser operation time,level of hemoglobin before and after operation,bladder irrigation time after operation,urinary catheter indwelling time,postoperative hospital stay,and intraoperative and postoperative complications were recorded.The changes of international prostate symptom score(IPSS),quality of life scale(QoL)score,maximum urinary flow rate(Qmax)and post-void residual volume(PVR)were compared before and 1 month after operation.Results The volume of prostate was(104.5±14.52)mL,the laser operation time was(20.13±2.98)min,and the bladder irrigation time was(20.27±2.56)h.The catheter was removed in all patients 2 days after operation,and all patients were discharged 3 days after operation.One month after operation,the IPSS,QoL,Qmax and PVR were significantly improved as compared with those before operation(P＜0.05).No complications occurred during the follow-up.Conclusion"Ditching and ridge removal"with 450 nm semiconductor blue laser is a new,safe and effective method in the treatment of large volume BPH.
