Treatment of teenage varicocele by transumbilical mini pure single-port laparoscopic Palomo's surgery: a report of 78 cases / 国际外科学杂志

Objective To evaluate the clinical superiority of transumbilical mini pure single-port laparoscopic Palomo's surgery on the treatment of primary teenage varicocele.Methods All operations were successfully completed using mini pure single-port laparoscopic Palomo's surgery.Its clinical effects were evaluated by the operative time,blood loss volume,intra-or post-operative complications,and hospital stay.Six to eighteen months after surgery,follow-up was made in 78 patients.Results All the operations were successful.The operation time was 5-15 (mean 8) minutes,the intra-operative loss blood was 1-5 (mean 1.5) mL,and the post-operative hospital stay was 2-4 (mean 3) days.No intra-operative or post-operative complications happened.Sperm analysis of 95％ patients came back to normal in 6-18 months.Conclusions The transumbilical mini pure single-port laparoscopic Palomo's technique has more obvious superiority and it is worthy of clinical application and generalized widely.

Determination of palmatine hydrochloride and berberine hydrochloride in Chinese Mahonia Stem from different habitats by HPLC / 中草药

Object To develop a method for the determination of palmatine hydrochloride and berberine hydrochloride in Chinese Mahonia Stem from different habitats Methods HPLC method was set up, using Intersil ODS 3 C 18 column, the mobile phase was acetontrile water sodium laurylsulfonate (470∶ 530∶1 g), the UV detection wavelength was 265 nm, with a flow rate of 1 0 mL/min at 40 ℃ Results A good linearity was obtained in the range of 4 368 52 416 ?g/mL(r=0 999 9) for palmatine hydrochloride and 4 532 54 384 ?g/mL (r=0 999 9) for berberine hydrochloride The average recovery of palmatine hydrochloride and berberine hydrochloride was 98 97% and 98 98%, respectively Conclusion The method is simple, rapid and with better reproducibility for the determination of palmatine hydrochloride and berberine hydrochloride in Chinese Mahonia Stem
