Objective To investigate the clinical, radiological features and therapy of spinal actinomycotic infection complicated with spinal cord compression.Methods The data of three patients confirmed by histopathology were analyzed retrospectively.Results All three patients presented with infection of cervical thoracal vertebral bodies and soft tissue, and with syndrome of spinal cord compression. MRI examination revealed destruction of vertebral bodies, extradural soft tissue mass and spinal cord compression. Histopathological examination confirmed the infection of actinomycete in all three patients. Granulomatous inflammation could be seen in two cases, while extradural abscess was found in the other one case. Three patients all received the operation of abscess draining and vertebral canal decompression. Large-dose of Penicillin G following operation was administrated intravenously for 4~8 weeks, and then changed to oral application for another 4~6 months. Follow-up showed significant clinical effect in these three patients.Conclusions Radiologic and clinical findings of spinal actinomycotic infection complicated with spinal cord compression are nonspecific, and the diagnosis of this disease depends on pathological and microbiologic exams. Treatments with abscess draining, vertebral canal decompression and large-dose of antibiotic may achieve good clinical outcome.

Objective To investigate endovascular treatment of traumatic direct carotid-cavernous fistulas (CCF) and their complications such as pseudoaneurysms. Methods: Over a five-year period, 22 patients with traumatic direct CCFs were treated endovascularly in our institution. Thirteen patients were treated once with the result of CCF occluded, 8 twice and 1 three times. Treatment modalities included balloon occlusion of the CCF, sacrifice of the ipsilateral internal carotid artery with detachable balloon, coil embolization of the cavernous sinus and secondary pseudoaneurysms, and covered-stent management of the pseudoaneurysms. Results All the direct CCFs were successfully managed endovascularly. Four patients developed a pseudoaneurysm after the occlusion of the CCF with an incidence of pseudoaneurysm formation of 18.2% (4/22). A total number of 8 patients experienced permanent occlusion of the ICA with a rate of ICA occlusion reaching 36.4% (8/22). Followed up through telephone consultation from 6 months to 5 years, all did well with no recurrence of CCF symptoms and signs. Conclusion Traumatic direct CCFs can be successfully managed with endovascular means. The pseudoaneurysms secondary to the occlusion of the CCFs can be occluded with stent-assisted coiling and implantation of covered stents.

Objective To establish the proposals of clinic and rehabilitation pathway for spine and spinal cord injury. Methods The experiences in clinic and rehabilitation treatment fields, the flow path of admission and the costs of hospitalization for spine and spinal cord injury patients in Chinese Rehabilitation Research Center were retrospectively summarized and analyzed. Related data in International Classification of Functioning, Disability and Health (ICF) core sets were also referred. Results The present proposals were applied to patients suffered from thoracic, lumbar or sacral spine injury with spinal cord injury. The proposals consisted of two parts: the surgical interventions in acute stage (within 2 weeks after injury) and clinic and rehabilitation treatments of spinal cord injury in sub acute and later stages (2 weeks to 6 months after injury). The criteria of surgical interventions in acute stage materialized the core therapies such as reconstruction of spine stability and neural decompression, etc. The criteria of treating spinal cord injury in subacute and later stages demonstrated the characteristic of combined therapy in which rehabilitation was the central element. Conclusion The establishment and implement of the present pathways were based on the time course of disease development and the staging feature of neural recovery and treatment after spinal cord injury. The purpose of this work is to improve the quality of medical service and reduce medical consumption.

The consensus has been reached on the benefits of surgical drainage. However, catheter-related blockage and retrograde infection remain bottleneck problems in the treatment process. To this end, with Huashan Hospital, Fudan University, as the main inventors, a drainage tube dredging umbrella and anti-retrograde infection kit have been designed and applied for the national utility model patent (patent number: ZL 2023 2 1300036.2). The main body of the kit consists of a catheter dredging umbrella, drainage tube, and drainage bag. Several isolation layers are installed in the drainage bag to form a maze structure and a reflux valve is added, thereby increasing the distance and resistance of liquid reflux, greatly reducing the possibility of liquid reflux entering the drainage tube, so as to reduce the risk of retrograde infection through physical means. When the drainage tube is blocked, the drainage tube and joint tube of the drainage bag can be separated, the unblocking umbrella can be inserted into the blockage through the guide wire, the cannula can be inserted along the guide wire, the guide wire is pulled to release the dredging umbrella in the contraction state, and the dredging umbrella can be pulled back in the expansion state until the blockage is removed from the drainage tube. The operating procedure is standardized and simple. While preventing retrograde infection (anti-retrograde infection kit), the catheter dredging umbrella could effectively address the issue of catheter blockage. It has certain clinical promotion and application value.

Objective:To observe the ratio of helper T cells 17 (Th17)/regulatory T cells (Treg) in peripheral blood of patients with Hashimoto's thyroiditis (HT) and the expression changes of related cytokines in serum, and to explore their role in the occurrence and development of HT.Methods:Using the case-control study method, 35 HT patients examined in the General Hospital of Heilongjiang Beidahuang Group from February to November 2019 were selected as HT group, and 39 healthy people in the same period were selected as control group. Early morning fasting venous blood samples of the two groups were collected to test the levels of thyroid stimulating hormone (TSH), free thyroxine (FT 4), thyroid peroxidase antibody (TPOAb) and thyroglobulin antibody (TgAb). The expressions of serum interleukin (IL)-6, IL-17 and transforming growth factor β (TGF-β) were tested by enzyme-linked immunosorbent assay (ELISA); the number of Th17, Treg in peripheral blood were determined by flow cytometry. Results:The levels of TPOAb, TgAb and TSH in HT group [130.60 (43.37, 714.40), 368.10 (136.90, 1 103.00) U/ml, 9.05 (6.62, 15.23) μU/ml] were significantly higher than those in control group [2.66 (1.52, 4.69), 12.63 (11.43, 14.60) U/ml, 1.87 (1.36, 2.23) μU/ml, U = 6.87, 6.62, 4.85, P < 0.001], and the FT 4 level [0.76 (0.63, 1.04) ng/dl] was lower than that in control group [1.14 (1.02, 1.26) ng/dl, U = 7.39, P < 0.001]. The expressions of IL-6, IL-17 and TGF-β in HT group were higher than those in control group ( t = 2.41, 9.04, 2.44, P < 0.05). The number of Th17 and the ratio of Th17/Treg in HT group were higher than those in control group ( t = 4.20, 3.50, P < 0.05), and the number of Treg was lower than that in control group ( t = 4.45, P = 0.001). Conclusion:In HT patients, Th17 are increased, Treg decreased, Th17/Treg ratio increased, and the expressions of IL-6, IL-17 and TGF-β are increased.
