Central venous lesion represents one of the common complications affecting vascular access in hemodialysis patients, potentially compromising hemodialysis efficacy. The management of symptomatic central venous lesion remains a critical challenge in clinical practice. Current primary treatment strategies include percutaneous transluminal angioplasty and percutaneous transluminal stenting. Advances in techniques such as sharp recanalization and the mother-child platform approach, along with the development of high-pressure balloons, paclitaxel- coated balloons, and covered stents, have significantly improved procedural success rates. However, unresolved issues persist, including standardized treatment protocols, technical considerations for lesion traversal, and optimal stent selection criteria. This article comprehensively reviews the treatment principles, lesion passage techniques, treatment techniques, and recent advancements of central venous lesion.

Objective:To observe the clinical efficacy of acupuncture plus point application in managing pain after thoracoscopic radical lung cancer surgery(TRLCS). Methods:A total of 120 patients undergoing TRLCS were randomized into a treatment group and a control group,with 60 cases in each group.Both groups received patient-controlled intravenous analgesia(PCIA)to relieve postoperative wound pain.The control group did not receive any other interventions.The treatment group started acupuncture treatments 4 h after the surgery with point application between two acupuncture sessions;the acupuncture treatment was conducted 4,24,48,and 72 h after the surgery.At the above 4 time points,the visual analog scale(VAS)score and additional PCIA drug consumption were recorded.The 5-hydroxytryptamine(5-HT)content in the peripheral blood was determined 4 h and 72 h after the surgery. Results:The treatment group was superior to the control group in comparing the total effective rate(P<0.05).After the intervention,the VAS score decreased in both groups(P<0.05);the VAS score presented different decreasing patterns at each time point in the two groups,and the score dropped more significantly in the treatment group than in the control group(P<0.05).The total PICA drug consumption varied in the two groups after the surgery;the additional analgesic consumption was notably smaller in the treatment group than in the control group(P<0.05).The decrease in the 5-HT content in the peripheral blood also varied in the two groups;the peripheral blood 5-HT content was significantly lower in the treatment group than in the control group(P<0.05). Conclusion:Acupuncture plus point application can significantly relieve wound pain after TRLCS.

Objective To study the expression of CD44v6 in non-small-celt lung cancer and significance in judgement of prognosis.Methods CD44v6 expression in non-small-cell lung cancer tissues was detected in 62 patients with lung cancer operation in 1995-2002 year by immunohistohemistry method.Results The positive rate of CD44v6 in NSCLC was 61.3%,which was related to lymph node metastasis and 3-year survival rate in patients,but not to cell differentiation,pathological sort and TNM stage.Conclusion The positive expression of CD44v6 may be involved in lymph node metastasis and survival rate in NSCLC patients.It might be useful to evaluate the possibility of cancer metastasis and prognosis.
