Chinese expert consensus and practice guideline of totally implantable access port for digestive tract carcinomas

Totally implantable access port is a fully implantable drug delivery system that is implanted subcutaneously and can be retained for a long time. Advantages of ports include a simple nursing process, low risk of infection and embolism, and high patient comfort. In order to promote the standardized application of ports in the treatment of digestive tract tumors and reduce port-related complications, the Chinese Research Hospital Association Digestive Tumor Committee, the Chinese Association of Upper Gastrointestinal Surgeons, the Chinese Gastric Cancer Association, and the Gastrointestinal Surgical Group of Chinese Surgical Society Affiliated to Chinese Medical Association have organized multidisciplinary expert discussions at the General Hospital of the People’s Liberation Army and nation-wide expert letter reviews and on-site seminars, and formulated an expert consensus of the operation guidelines.

Clinical effects of graded psychological nursing care in elderly patients with digestive tract tumors undergoing elective surgery

AIM: To evaluate the clinical effects of graded psychological nursing care in elderly patients with gastrointestinal tumors undergoing elective surgery.

METHODS: One hundred and forty-five elderly patients undergoing selective surgery for gastrointestinal tumors were divided into two groups: an experimental group and a control group. The experimental group was given graded psychological nursing care, and the control group was given routine nursing care. Clinical effects were compared for the two groups

RESULTS: In the experimental group, scores of postoperative anxiety, depression, and sleep quality were significantly lower than those before operation (P < 0.05); in the control group, postoperative anxiety score was significantly lower than preoperative anxiety score (P < 0.05). In the experimental group, postoperative anxiety, depression and sleep quality scores were significantly lower than those in the control group (P < 0.05), and operation compliance and inpatient satisfaction scores were significantly higher than those in the control group (P < 0.05). The rate of poor compliance incidents in the experiment group was significantly lower than that in the control group (P < 0.05). Poor compliance incidents in the two group included unplanned extubation, failure to cough, not following diet directions, inappropriate self care for artificial anus, treatment, nursing or exercise rejection as early as possible and failure to control mood.

CONCLUSION: Graded psychological nursing care in elderly patients with digestive tract tumors undergoing elective surgery can enhance the patients' compliance and improve their satisfaction.

CProgress of research on the relationship between Wnt signal transduction and digestive tract tumors

The Wnt signal transduction pathway plays an important role in controlling embryo development; its abnormal elevation is involved in many types of human tumorigenesis, and it has a close relationship with digestive tract tumors. Wnt antagonists can block Wnt signal transduction and inhibit its abnormal elevation, and therefore may provide a potential new anti-cancer therapy.
