ObjectiveTo understand the research advance of photodynamic therapy (PDT) on cholangiocarcinoma. MethodDomestic and international publications online which involving the research of PDT on cholangiocarcinoma in recent years were reviewed. Results①PDT was a new therapy on tumor from the tissue and cell level, which could destroy the target tissue and cell under the photochemical reaction and kill the tumor cell according to the characteristics of the selective intake of tumor tissue on particular photosensitizer. It could mainly induce tumor cell apoptosis and necrosis, destroy the tumor microvascular, stimulate the immune and inflammatory response.②PDT on the research level of the treatment of cholangiocarcinoma had achieved fairly good curative effects, which could make the tumor shrinkage, reduce the harm to normal bile duct cell, and prolong the survival, improve the survival rate and the quality of life.③Proliferating cell nuclear antigen (PCNA), vascular endothelial growth factor-C (VEGF-C), and cyclooxygenase-2 (COX-2) played important roles in the development of cholangiocarcinoma. PDT could inhibit the expressions of PCNA, VEGF-C, and COX-2, and then could promote cell apoptosis, and then inhibit cell proliferation. ConclusionsPDT is a new technology in treatment of malignant tumor, which whether used alone or combined with other methods has less adverse reaction and could obviously improve the local symptoms in treatment of cholangiocarcinoma. But many problems about PDT need to be solved at present, in the base areas, such as research and development of new photosensitizer and precise mechanism of killing tumor, in the clinical applications, such as selection and application of photosensitizer, ways and parameters of the laser, formulation of treatment plans and the reduction of the complications.
Choroidal metastasis of lung cancer is rare in clinical, which is easy to missed diagnosis or misdiagnosis, special research and discussion are not much. This article mainly introduces the current situation of choroidal metastasis of lung cancer in China, the characteristics of clinical and ophthalmoscopic examination, angiography and imaging, the methods of early detection, early diagnosis and the progress of individualized comprehensive treatment. It is expected to attract the attention of thoracic surgeons, conducive to improve the quality of life and prognosis of patients.
目的了解腹腔镜肝切除术（laparoscopic hepatectomy，LH）与开腹肝切除术（open hepatectomy，OH）治疗原发性肝癌的围手术期状况的变化。 方法回顾性分析2012年1月至2013年6月期间青岛大学医学院附属医院肝胆外科收治的40例原发性肝癌患者的临床资料，其中20例行LH，20例行OH，比较2组患者的术前一般情况、术中情况和术后恢复情况。 结果2组患者术前一般情况的差异均无统计学意义（P＞0.05）；在切口长度、术中出血量、术后肝功能指标、胃肠功能恢复情况和术后住院时间方面LH具有明显的优势（P＜0.05），而在手术时间、术后并发症和住院总费用方面2组间差异无统计学意义（P＞0.05）。 结论LH较传统的OH可明显改善肝癌患者的围手术期状况，值得在有条件的情况下开展推广。
