Percutaneous transforaminal endoscopic discectomy via lateral position assisted with local anesthesia for lumbar disc herniation in elder with systemic diseases / 中国骨伤

OBJECTIVE@#To explore the clinical effect of percutaneous transforaminal endoscopic discectomy via lateral position assisted with local anesthesia for lumbar disc herniation in elder with systemic diseases.@*METHODS@#The clinical data of 44 elder patients with lumbar disc herniation and systemic diseases treated from June 2013 to June 2017 were retrospectively analyzed. Including 26 males and 18 females, aged 70 to 86 years old with an average of(77.5±3.5) years, course of disease was 3 weeks to 6 months. Percutaneous transforaminal endoscopic discectomy via lateral position assisted with local anesthesia was performed in the patients. Postoperative straight leg-raising degree change and Nakai criteria were used to evaluate the operative effect. Visual analogue scale(VAS) and JOA scoring system were used to compare the symptom improvement between preoperative and postoperative.@*RESULTS@#No serious complications occurred during and after the operation, and the coexisting medical diseases were not aggravated. All patients safely survived the perioperative period. All the 44 cases were followed up from 6 to 30 months with an average of 20 months. Postoperative straight leg raising angle was obviously improved. At final follow-up, according to Nakai standard, 41 cases got excellent results, 3 good. VAS scores were significantly decreased and JOA scores were significantly increased in final follow-up(<0.01).@*CONCLUSIONS@#Percutaneous transforaminal endoscopic discectomy via lateral position assisted with local anesthesia is a safe, effective, less invasive technique for the treatment of lumbar disc herniation in elder with systemic diseases. Multidisciplinary collaboration and perioperative well controlled disease are essential for early rehabilitation of such patients.

Screening of Anti-tumor Activity from Ten Polypores Fungi in vitro / 微生物学通报

The anti-tumor activity of fermentation and the ethanol extraction of ten Polyprous fungi against human lung cancer cell NCI-H460 were determined by MTr method,the effect of medium and time for cultivation on the anti-tumor activity were studied.The results showed that the fermentation liquid of Onnia tomentosa and Ceizene unicolon and the mycelium ethanol extract of Formitopsis pinicola had obvious an- ti-tumor activity,the tumor inhibiting ratio of mycelium ethanol extract of Formitopsis pinicola cultivated in Potato-woodehipping medium was 88.87% at the concentration for 500?g/mL,and the inhibiting ratio had little change when Formitopsis pinicola cultivated in different medi- um and for different days.
