Comparison of 2 µm continuous-wave laser enucleation of the prostate and transurethral resection of the prostate for benign prostatic hyperplasia / 中华外科杂志

<p><b>OBJECTIVE</b>To compare the safety and efficacy of RevoLix 120 W 2 µm continuous-wave (cw) laser enucleation of the prostate with transurethral resection of prostate (TURP) in patients with symptomatic benign prostatic hyperplasia (BPH). And to evaluate clinical value of 120 W 2 µm cw laser enucleation.</p><p><b>METHODS</b>All 168 patients with BPH underwent 2 µm cw laser enucleation (n = 88) or TURP (n = 80) between January 2010 and January 2011. The operative time, drop in hemoglobin, drop in serum sodium, indwelling catheterization time and operative complications were recorded. International prostate symptom score (IPSS), quality of life (QOL), urinary peak flow rate (Qmax) and post-voiding residual urine (PVR) were also compared.</p><p><b>RESULTS</b>The mean operative time was slightly longer in the 2 µm laser group ((63.2 ± 21.6) min) than the TURP group ((59.4 ± 18.6) min) (P > 0.05). Transfusions were not necessary in 2 µm laser group. Catheter indwelling time were (1.8 ± 0.6) days vs. (3.5 ± 2.6) days in 2 µm laser group than in TURP group (t = 3.912, P < 0.05). All cases were followed up for 3 - 12 months, the IPSS, QOL, Qmax and PVR were 6.1 ± 2.0, 4.4 ± 1.6, (18.8 ± 4.8) ml/s and (21.6 ± 16.5) ml in the 2 µm laser group, and were 6.3 ± 2.4, 1.9 ± 1.1, (18.4 ± 4.2) ml/s, (23.2 ± 14.6) ml in TURP group respectively. All the markers were improved significantly compared with that of preoperative in both groups (t = 12.453 - 26.213, P < 0.01), but no statistical differences could be found between the two groups. Perioperative complications were less in the 2 µm laser group.</p><p><b>CONCLUSIONS</b>The 120 W 2 µm cw laser enucleation is an novel excellent treatment for BPH as well as TURP, and has the advantage of significantly less blood loss, shorter hospitalization, shorter catheter indwelling time and rapid recovery after surgery.</p>

Jinleng method is effective and safe for the treatment of oligospermia and asthenospermia / 中华男科学杂志

<p><b>OBJECTIVE</b>The Jinleng method is based on the principle of lowered temperature and diathermic action on the testis. The aim of this study is to investigate the effect and safety of the Jinleng method on oligospermia and asthenospermia.</p><p><b>METHODS</b>We treated 39 infertile males with oligospermia or asthenospermia with Jinleng underpants (Jinleng method) bid for 3 months, observed the changes in the sperm parameters of the patients after the treatment and recorded the pregnancy outcomes of their wives.</p><p><b>RESULTS</b>Of the 36 patients who accomplished the treatment, 31 showed significantly improvement in semen volume, sperm concentration, forward sperm motility, total sperm motility, total sperm count and total motile sperm count (P < 0.05), with an effectiveness rate of 86.1%. Five of the patients wives achieved pregnancy in the 2-month follow-up. Adverse effects were found in none of the patients.</p><p><b>CONCLUSION</b>Jinleng method is effective and safe for the treatment of infertile males with oligospermia and asthenospermia.</p>

The protection of seed oil of Hippophae rharmnoides on ischemic cerebral infarction in rats / 中国中药杂志

<p><b>OBJECTIVE</b>To study the protection of seed oil of Hippophae rhamnoides on ischemic cerebral infarction in rats and the mechanism of the action.</p><p><b>METHOD</b>Focal cerebral ischemia model was made by middle cerebral artery occlusion(MCAO) in rats. Behavior obstacles of rats were observed. Cerebral infarction volume was determined by Megnetic Resonance Imaging(MRI).</p><p><b>RESULT</b>Seed oil of Hippophae rhamnides 0.7 and 0.35 g.kg-1 could markedly reduce infarction volume after occlusion of middle cerebral artery in rats and also could ameliorate the behavior obstacles of rats.</p><p><b>CONCLUSION</b>These results suggested that seed oil of Hippophae rhamnoides had distinct protection to ischemic cerebral infarction in rats.</p>
