Objective To investigate the efficacy and toxicities of gemcitabine and cisplatin as a chemother-apy regimen for patients with advanced non-small cell lung cancer (NSCLC). Methods Thirty-five patients with NSCLC were enrolled in this study. C, emeitabine was given on day 1 and 8 at a dose of 1000 mg/m~2 and cisplatin at a dose of 25 mg/m~2 on day 1 to 3. The chemotherapy was repeated every 28 days, after 2 cycles for evaluating response. Results Complete response (CR), partial response (PR) ,stable disease (SD) and progressive disease (PD) were observed in 0,14,16 and 5 cases, respectively, with a response rate (RR) of 40. 0%. The RR in initial treatment group was found more than that in the retreatment group (52. 2% vs 16.7% ,P<0. 05).The main toxicities were tol-erable, which included myelosuppression, nausea, vomiting, and liver damage. Conclusion Gemcitabine combined with cisplatin is effective and safe in the treatment of NSCLC, especially in the initial treatment patients.

Objective:To explores the clinical efficacy and safety of carotid endarterectomy in patients with high bifurcation carotid artery stenosis.Methods:A total of 169 patients with carotid artery stenosis (147 patients with non-high bifurcation carotid artery stenosis and 22 patients with high bifurcation carotid artery stenosis), underwent carotid endarterectomy under surgical microscope in our hospital from January 2017 to January 2020, were included in the study. Patients with high bifurcation carotid artery stenosis were operated by cutting off the posterior abdomen of the digastric muscle to assist in exposing the distal end of the internal carotid artery plaque. Cervical CTA/DSA examination was performed within one week of surgery to confirm whether carotid artery stenosis was relieved; ultrasound examination of cervical vessels was performed 6 months and 1 year after surgery to determine whether restenosis was appeared in the carotid artery. The surgical efficacy, perioperative complications and re-examination results were compared between the two groups.Results:Postoperative carotid artery stenosis was relieved in both groups. The proportions of new cerebral infarction and temporary neurological impairment between the two groups (4.5% vs. 2.0%; 9.1% vs. 3.4%) showed no significant differences ( P>0.05). Carotid artery restenosis was not found in both groups. There was no obvious functional abnormality in the digastric muscles of patients with high bifurcation carotid stenosis. Conclusion:Cutting off the posterior abdomen of the digastric muscle during carotid endarterectomy can better expose the distal end of the internal carotid plaque in patients with high bifurcation carotid stenosis, and provide convenience for effective relief of carotid artery stenosis with high safety.
