Objective To observe changes of the structure and function of microvessels during the formation and development of the rat cerebral glioma with steady-state susceptibility contrast-enhanced MR imaging. Methods A total of 30 bearing-tumor rats were divided into 3 groups (1-week group, 2-week group and 3-week group) and underwent MR examination. Blood volime (BV) and vessel size index (VSI_(MRI)) of peripheral tumor areas, central tumor areas and normal cerebral tissue in the opposite side were measured, and compared with histologic findings. Results With time of bearing-tumor increasing, BV of central tumor area present an up-and-down curve-like change, which related to the host blood vessel regression in tumor central area, the decreasing of blood vessel density and histopathologically obvious necrosis. BV of peripheral tumor areas increased because of active blood angiogenesis in this area, while VSI_(MRI) increased gradually, especially in the central tumor area. There was obviously correlation between the VSI_(MRI) and VSI _(histo) (P<0.01). Conclusion BV and VSI_(MRI) can exactly reflect the morphology and functional information of microcirculation of tumor during the growth and development of gliomas.

Objective To explore the of value steady-state susceptibility contrast-enhanced MRI (SSCE-MRI) in assessment of anti-angiogenesis therapy in rat C6 glioma. Methods Seventeen rats with the bearing-tumor were randomly divided into the therapy group (n=8) and the contrast group (n=9). Human-recombination endostatin (10 mg/kg) was injected to animals in therapy group, and saline of the same dose was injected to the contrast group for 7 days. Blood volume (BV) and vessel size index (VSI) were measured of tumors in peripheral, central and normal areas with MR pre- and post-therapy. Results After therapy of endostatin, the tumor volume was obviously different between therapy group and contrast group (t=5.26, P<0.05). BV and VSI_(MRI) of tumor decreased in both peripheral and central areas, particularly in the peripheral area (t=4.14, 3.66, all P<0.01). Conclusion Assessment of therapeutic effect of anti-angiogenesis in C6 glioma is feasible with SSCE-MRI, and it can reflect the changes of BV and VSI_(MRI) pre- and post-therapy.

Abstract
Fangjiomics is a promising paradigm that enhances research on multi-omics-based pharmacological mechanisms of Fangji from holistic and systematic perspective. We reviewed recent advances in Fangjiomics, focusing on database and analysis platform development, methodological innovations, and translational applications. Through the integration of Fangji and multi-omics data, multi-level system analysis approaches were developed, encompassing single-target analysis, signaling pathways, multi-targeted network and modules. Fangjiomics has emerged as a key strategy in various areas of Fangji research. To support the high quality development of Fangjiomics, we propose principles and perspectives from the integrated, macro-level, and practical viewpoints.

BACKGROUND:Hidden blood loss is an important risk for the intertrochanteric fracture patients, especial y the elderly patients, which can cause anemia in patients after internal fixation and can affect wound healing and patient recovery. OBJECTIVE:To compare the perioperative hidden blood loss and the risk factors of proximal femoral anti-rotation intramedul ary nail internal fixation and dynamic hip screw fixation for the treatment of femoral intertrochanteric fracture. METHODS:We selected 70 cases of femoral intertrochanteric fracture patients who treated with proximal femoral anti-rotation intramedul ary nail and dynamic hip screw fixation, including 21 patients with the age ≥ 80 years and 49 patients with the age<80 years;28 patients with the body mass index>30 kg/m2 and 42 patients with the body mass index ≤ 30 kg/m2;30 patients received anti-rotation intramedul ary nail internal fixation and 40 patients received dynamic hip screw fixation. The perioperative blood loss was calculated with Gross formula according to the changes of height, body mass index and the hematocrit before and after fixation. RESULTS AND CONCLUSION:The mean total blood loss was 936 mL, the mean dominant blood loss was 237 mL and the mean hidden blood loss was 699 mL. The hidden blood loss was accounted for 74.7%in total blood loss. The dominant blood loss in the dynamic hip screw fixation group was higher than that in the anti-rotation intramedul ary nail internal fixation group, and the hidden blood loss was lower than the anti-rotation intramedul ary nail internal fixation group. The total blood loss and the hidden blood loss of the elderly patients were higher than those of the non-elderly patients;there was no significant difference between male and female patients, obesity and normal patients. The results indicate that hidden blood loss is the major reason for total blood loss of femoral intertrochanteric fracture after internal fixation. The hidden blood loss of anti-rotation intramedul ary nail internal fixation is larger than that of dynamic hip screw fixation, and elder is the risk factor for hidden blood loss.
