ABSTRACT
Radiation-induced intestinal injury is a radiation injury of the colon and rectum after radiotherapy for pelvic malignant tumors. This condition affects multiple organs in the pelvis, making treatment challenging. In clinical practice, the most effective protocol is often determined through discussion by a multi-disciplinary team (MDT). However, due to the severity and complexity of radiation enteritis, many patients still experience poor diagnosis and treatment outcomes. Holistic integrative management (HIM) is a rapidly developing concept that has greatly enhanced clinical medicine in recent years. It improves the level of diagnosis, treatment, prevention, and rehabilitation from multiple dimensions of prevention, screening, diagnosis, treatment, and rehabilitation. In the context of radiation-induced intestinal injury, HIM also calls for the implementation of an individualized management system that focuses on the patient as a whole within the healthcare team. From the perspective of HIM, this article introduces some of the latest progress of radiation-induced intestinal injury in recent years.

The three anti-complementary neutral polysaccharides, IA-1, IB-1 and IC-1, were purified from the leaves of Artemisia princeps by anion-exchange chromatography, gel filtration and affinity chromatography. The order of the anti-complementary activity was IA-1 > IB-1 > IC-1. The polysaccharides appeared to be homogeneous from the results of gel filtration, HPLC and electrophoresis. The M(r)s of IA-1 IB-1 and IC-1 were estimated to be 56,000, 16,000, and 7000, respectively, by HPLC. IA-1 consisted mainly of arabinose (Ara), galactose (Gal) and glucose (Glc) in molar ratios of 1.8:1.0:0.9, whereas IB-1 and IC-1 were composed mainly of Ara, mannose (Man), Gal and Glc in molar ratios of 3.5:0.8:1.0:0.8 and 2.3:3.5:1.0:3.2, respectively. Methylation analysis, 13C NMR and enzymic digestion suggested that IA-1 mainly contained alpha-L-(1-->3,5)-arabinan, beta-D-(1-->6)-linked Gal and beta-D-(1-->3)-linked Glc. IB-1 also consisted mainly of alpha-L-(1-->3,5)-arabinan and beta-D-(1-->6)-linked Gal, whereas IC-1 was composed mainly of beta-D-(1-->4)- linked Glc and alpha- or beta-D-(1-->4)-linked Man.

Rhodiola sachalinensis polysaccharides (RSP) isolated from the root of Rhodiola sachalinensis was demonstrated to decrease the levels of blood sugar, liver glycogen and total blood lipid when injected peritoneally to mice at 50, 100 and 200 mg/kg once or for 7 successive days. In addition, RSP was found to decrease blood sugar and total blood lipid in various experimental hyperglycemias induced by injection of adrenaline, glucose and alloxan in mice. RSP exhibit inhibiting effect on the glycogen enhancement induced by glucose as well as strenghtening effect on the glycogen decomposition induced by adrenaline and alloxan.
