Present and Future Prospects of the Anti-cancer Activities of Saikosaponins.

Since their discovery, saikosaponins (SSs) have been found to play an important role in treating a variety of cancers via diverse mechanisms of action. This review summarizes the current research status and prospects of the anti-cancer activities of SSs, providing novel insights into the limitations of current studies. In addition, it discusses whether SSs can be applied in immunotherapy and the possible mechanisms by which SSs may facilitate immunotherapy. The research is significant to understanding the anti-cancer potents of SSs in the development of SSs-based therapeutic strategies and clinical practice.

[Small intestinal cavernous hemangioma causing chronic hemorrhage: a case report].

Small intestinal hemangioma is a rare condition that can be divided histologically into capillary, cavernous or mixed types, among which the cavernous type is the most common. Here we report a case of small intestinal cavernous hemangioma with chronic hemorrhage in 44-year-old man. The patient complained of weakness and dizziness for 2 years that aggravated 1 month before admission accompanied by intermittent melena. Laboratory tests suggest severe anemia, and computed tomography, gastroscopy and colonoscopy all revealed signs of anemia. Capsule endoscopy detected small intestinal erosions, bleeding lesions and prominent neoplasms. An exploratory laparotomy was performed, in which the segment of the jejunum with lesions was resected. Pathological examination of the resected jejunum identified the neoplasm as cavernous hemangioma of the small intestine, which was the cause of severe anemia.

Duodenal Bulb Adenocarcinoma Benefitted from Neoadjuvant Chemotherapy: A Case Report.

Duodenal bulb adenocarcinoma is an extremely rare malignancy in the alimentary tract which has a low incidence rate and nonspecific symptoms. It is difficult to diagnose early, and the misdiagnosis rate is high. CT, MRI, upper gastrointestinal endoscopy, and other advanced imaging modalities should be combined to make a comprehensive evaluation. The diagnostic confirmation of this tumor type mainly depends on the pathological examination. The combination of surgery with other treatment modalities is effective. A review of reports on duodenal bulb adenocarcinoma with chemotherapy revealed 6 cases since 1990. However, there are few reports on neoadjuvant chemotherapy for the disease. In this report, preoperative S-1 in combination with oxaliplatin neoadjuvant chemotherapy achieved a complete pathological response in the treatment of duodenal bulb adenocarcinoma. Neoadjuvant chemotherapy shows a better clinical efficacy in the treatment of duodenal bulb adenocarcinoma, but its value needs to be further verified.
