Objective: To establish an experimental unilateral internal carotid artery stenosis model in New Zealand albino rabbits that can be detected in vivo. Methods: A 2 F Foley's tube was inserted into unilateral carot id artery for performing intimal injury in 5 rabbits, and causing intimal hyperplasia and angiostenosis. The hemodynamic changes of unilateral carotid artery were detected by transcranial Doppler (TCD); the reduction of cerebral blood flow (CBF) after stenosis was calculated by mathematical formulas. The degree of stenosis was confirmed by digital subtraction angiography (DSA), and the arterial intimal hyperplasia and stenosis were confirmed by pathological examination. Results: Two rabbits survived after the procedure. TCD, DSA and pathological examination showed that the model of experimental unilateral internal carotid artery stenosis in rabbits was established successfully. The reduction of CBF after unilateral internal carotid artery stenosis was calculated in the 2 rabbits, they were 17% and 45%, respectively. Conclusion: The rabbit model of unilateral internal carot id artery stenosis has been established successfully, and the severity of stenosis can be detected and evaluated in vivo.

Acute pancreatitis (AP) is activated trypsin-induced pancreatic and its peripheral tissue inflammation caused by their own digestion.The activation in advance of trypsinogen and the inflammation cascade in pancreatic acinar cells are thought to be a key mechanism of the onset and development of AP.Autophagy pathway acting as Ⅱ type of programmed cell death occurs in the early pathological course of AP,blockade of which contributes to aggravating necrosis of acinar cells in AP.This article mainly discussed the recent advances in the understanding of autophagy researches and its function in the mechanism of AP.

Objective To discuss the value of enlargement of geniculate fossa of facial nerve canal in the diagnosis of facial nerve canal fracture.Methods Thirty patients with facial nerve canal fracture underwent axial and coronal CT scan.The correlation between the fracture and the enlargement of geniculate fossa of facial nerve canal was analyzed.The ability of showing the fracture and enlargement of geniculate fossa of facial nerve canal in axial and coronal imaging were compared.Results Fracture of geniculate fossa of facial nerve canal was found in the operation in 30 patients,while the fracture was detected in CT in 18 patients.Enlargement of geniculate ganglion of facial nerve was detected in 30 patients in the operation,while the enlargement of fossa was found in CT in 28 cases.Enlargement and fracture of geniculate fossa of facial nerve canal were both detected in CT images in 18 patients.Only the enlargement of geniculate fossa of facial nerve canal was shown in 12 patients in CT.Conclusion Enlargement of geniculate fossa of facial nerve canal was a useful finding in the diagnosis of fracture of geniculate fossa in patients with facial paralysis,even no fracture line was shown on CT images.

BACKGROUND: Posterior internal fixation and fusion system is a main method for chronic back pain caused by intervertebral disc degeneration, but more postoperative adverse reactions occur. Dynamic stabilization system can reduce adjacent-segment degeneration, and theoretically, repair intervertebral disc degeneration.OBJECTIVE: To investigate the efficacy and safety of K-rod dynamic stabilization system in the repair of lumbar degenerative diseases.METHODS/DESIGN: We conducted a prospective, single-center, self-controlled, clinical trial at the Orthopedic Hospital of Shenyang, China. Sixty-seven patients with lumbar degenerative diseases were enrolled, and treated with K-rod dynamic stabilization system. All patients were followed for 2 years. The primary outcome was the changes in the Oswestry dysfunction index scores at baseline, 3, 6, 12 and 24 months postoperatively. The secondary outcomes were the ratio of height vertebral space to body and lumbar lordotic angle at baseline, 3, 12 and 24 hours postoperatively; the visual analogue scale scores for back pain and morphological changes in the lumbar vertebrae on x-ray preoperatively and 3, 6, 12 and 24 months after surgery; the incidence of adverse reactions at 3, 6, 12 and 24 months postoperatively.This trial has been registered at ClinicalTrials.gov (identifier: NCT03214042). The study protocol has been approved by the Ethics Committee of Orthopedic Hospital of Shenyang. All protocols will be performed in accordance with the Ethical Principles for Medical Research Involving Human Subjects in the Declaration of Helsinki. Written informed consent was provided by each patient after they indicated that they fully understood the treatment plan.DISCUSSION: This trial was designed to investigate the efficacy and safety of K-rod dynamic stabilization system for lumbar degenerative diseases, thus providing reference for its clinical application. Partial results demonstrated that the Oswestry Dysfunction Index and Visual Analogue Scale scores at 24 months postoperatively were significantly improved (P < 0.01), but the ratio of height vertebral space to body and lumbar lordotic angle did not differ significantly at different time points (P > 0.01). These results suggest that K-rod dynamic stabilization system can alleviate pain and improve lumbar function in the patients with lumbar degenerative diseases.

Objective To analyze the clinicopathologic characteristics and evaluate the influence factors for the prognosis of rectum carcinoma patients who had undergone surgical resection. Methods A retrospective analysis of data of 272 patients with rectum carcinoma in TNM stage Ⅰ, Ⅱ, Ⅲ was made, all these patients underwent R0 surgical resection from 1998 to 2002 in the General Hospital of PLA. The survival rate was analyzed by Kaplan-Meier method. The clinical characteristics and pathologic features were compared with the aid of monofactorial and multifactorial Cox regression analyses. Results The median survival time was 58.5 months, and the 1-, 3- and 5-year survival rates of rectum carcinoma after surgical resection were 79%, 70% and 62%, respectively. With monofactorial analysis, preoperative CEA level, diameter of tumors, differentiation degree of tumor, depth of tumor invasion, the number of metastatic lymph nodes and TNM staging were found to be significant factors influencing the prognosis. Adjuvant chemotherapy after surgery had influence over the survival rates of stage Ⅱ and Ⅲ rectal carcinoma. Age, gender, histological type and infiltration of canalis haemalis were uncorrelated with prognosis. Preoperative CEA level, depth of tumor infiltration and the number of metastatic lymph nodes were proved independently to be the risk factors influencing prognosis by multifactorial analysis. Conclusions The tumor site was not the prognostic factor of rectal carcinoma after R0 surgical resection. Preoperative CEA level, infiltration and the number of metastatic lymph nodes were independent prognostic factors in predicting the postoperative outcome. Careful preoperative assessment, early radical surgery and adjuvant chemotherapy after operation can improve the survival rate in rectum carcinoma patients.
