Traumatic deep vein thrombosis is a venous thrombotic disease which are secondary to trauma or surgery.This thrombotic disease is the most common clinical complication in surgery,especially in orthopedic surgery.The article overviews recent prediction indicators of academic value on traumatic deep vein thrombosis from six facts contain gene,inflammation,coagulation factor,supplementary examination,lipid molecules and selectin.These new indicators will play a more active role in prediction and treatment for traumatic deep vein thrombosis.

Objective: To explore the effect of enteral nutrition on tumor cell proliferation activity in rectal cancer patients with nutritional risk treated with preoperative neoadjuvant therapy. Methods: Sixty-six rectal cancer patients with nutritional risk treated with preoperative neoadjuvant therapy from January 2016 to January 2018 in the Yongchuan Hospital Affiliated to Chongqing Medical University were selected. The patients were divided into experimental group (enteral nutrition combined with neoadjuvant therapy) and control group (simple adjuvant therapy) according to the random digits table method, with 33 cases in each group. The expressions of proliferating cell nuclear antigen (PCNA) and Ki-67 antigen before and after treatment were detected by immunohistochemical method; the albumin and prealbumin before and after treatment were observed, and the nutrition risk screening 2002 (NRS2002) was evaluated. Results: There were no statistical differences in the expressions of PCNA and Ki-67 antigen before treatment between 2 groups (P>0.05); the expressions of PCNA and Ki-67 antigen after treatment in experimental group were significantly lower than those in control group, and there were statistical differences (P<0.05). There were no statistical differences in the NRS2002 score, albumin and prealbumin before treatment between 2 groups (P>0.05); the NRS2002 score after treatment in experimental group was significantly lower than that in control group: (1.58 ± 0.50) scores vs. (3.65 ± 0.72) scores, the albumin and prealbumin after treatment were significantly higher than those in control group: (35.92 ± 2.77) g/L vs. (31.12 ± 1.76) g/L and (204.58 ± 23.86) mg/L vs. (157.46 ± 18.99) mg/L, and there were statistical differences (P<0.01). Conclusions Enteral nutrition can reduce the proliferation activity of tumor cell in rectal cancer patients with nutritional risk treated with preoperative neoadjuvant therapy, and it can improve the nutritional status of patients.
