Objective To retrospectively review the experience and early clinical result of carotid endarterectomy (CEA) for the treatment of symptomatic carotid artery stenosis. Method CEA was performed on 82 consecutive patients (66 males, 16 females), age ranged from 48 to 84 years (mean 68.6 years). Diagnosis was established by carotid artery Doppler ultrasonography and DSA in all patients. General anesthesia was used in 39 cases, regional anesthesia was used in 43 cases. Temporary intraluminal shunts were used in 56 patients. Results There was no surgical mortality. Postoperatively 76 patients were followed up from 4 months to 18 months. Symptoms significantly improved in 57 cases, mild improvement was achieved in 14 cases, severe postoperative complication occurred in 3 patients, including cerebral ischemia in 2 cases, intracarotid thrombosis in one. Conclusion CEA is an effective therapy for the treatment of symptomatic carotid artery stenosis.

Based on the framework and approaches of International Classification of Functioning, Disability and Health (ICF) and psychometry,the theory and methods of the development and standardization of functioning and disability measurement for stroke were reviewed.

Objective To investigate the changes in endothelial progenitor cells (EPCs) number in peripheral blood of patients with acute cerebral infarction and after Naoxintong treatment.Methods Sixty patients were selected as subject and randomly divided into aspirin group and aspirin (30 patients) + Naoxintong group (30 patients).Meanwhile 30 patients without cerebral infarction were served as control group The number of peripheral blood EPCs were detected by flow cytometry at different time point.NIH-NINDS stroke score was used to elevate the neurological function.Results Compared with the control group,number of peripheral blood EPCs significantly decreased in the early stage of acute cerebral infarction (P ＜ 0.05),and then gradually increased until 7th day,which was back to the normal level.There was a positive correlation between improvement of NIHSS and number of peripheral blood EPCs in acute cerebral infarction.Compared with aspirin group,the number of peripheral blood EPCs in Naoxintong group increased sigrificanfly [41.40 ±0.18/million cells vs 41.40 ±0.18/million cells] at 14th day in patients treated with aspirin and Naoxintong.Conclusion The number of peripheral blood EPCs showed a U shape dynamic change in acute cerebral infarctior.Increase the number of peripheral blood EPCs might improve prognosis in patients with acute cerebral infarction.On the basis of routine treatment of aspirin,Naoxintong plus aspirin treatment might improve the number of peripheral blood EPCs in acute cerebral infarction.

Objective To explore the unmet needs and service of rehabilitation for Chinese people with disabilities. Methods The unmet needs and services of rehabilitation data from the Second National Sample Survey of Disability and 2006-2016 Statistical Bulletin on the De-velopment of People with disabilities in China issued by China Disabled Persons Federation had been analyzed. Results The unmet needs of rehabilitation for people with disabilities in China were mainly included health care and support, assistive devices, rehabilitation therapy and services, poverty alleviation, accessible facilities, accessible information, and other rehabilitation needs. The highest rate of unmet needs of rehabilitation was in the fields of health care (34.84%) and poverty alleviation (33.25%). There were significant differences in unmet needs of rehabilitation among people with different types of disabilities (χ2=40322.1, P<0.01). For all the types of disabilities, 41.46%had not re-ceived any service and support, 30.45%received health care and support, and 0.55%received accessible information. The main approaches recommended by professionals for people with disabilities were institutional rehabilitation, and community and family based services. The main services recommended by professionals to people with psychiatric (68.18%) or visual disabilities (60.28%) were health care, to people with hearing disability (51.67%) were assistive device, and to people with intellectual (57.36%) and speech disability (47.06%) were rehabil-itation therapy and training. There were significant differences both in rehabilitation approaches and contents among people with different types of disabilities preferred by professionals (χ2=12489.9,χ2=52528.93, P<0.01). Conclusion The unmet needs of rehabilitation for people with different types of disabilities were mainly included health care and assistance, assistive devices, rehabilitation training and services, and poverty alleviation. There were significant differences among people with different types of disabilities. For service delivery, the highest rate was in health care and assistance. The gap between the service and unmet needs of poverty alleviation for people with disabilities in China was the highest. There were significant differences in rehabilitation approaches and contents recommended by professionals among people with different types of disabilities. It was recommended to construct the national and local system of policy support system and rehabilita-tion service governance, to provide precision rehabilitation services based on the unmet needs of rehabilitation, to develop the comprehen-sive rehabilitation service delivery to achieve the goal of rehabilitation for all, and to conduct scientific research on rehabilitation by using International Classification of Functioning, Disability and Health to provide evidence and support for the development of rehabilitation.

Objective To investigate the strategies of reducing the incidence of missed diagnosis of severe traumatic brain injuries combined with multiple trauma. Methods Data of 432 patients with severe traumatic brain injuries and multiple trauma (ISS≥20) from January 2000 to August 2007 were analyzed retrospectively. All patients were divided into missed diagnosis group (MD group, n =54) and non-missed diagnosis group (NMD group, n =378) for correlation analysis on ISS, GCS, anatomical locations of the missed diagnosis, the time of delayed diagnosis and the prognosis. Results ISS was (42.97±10.94) points in MD group, with statistical difference compared with NMD group (P < 0.05). The patients with GCS≤8 in MD group was more than those in NMD group (P < 0.05). Conclusions It is effective to prevent missed diagnosis and improve the survival of patients with severe traumatic brain injuries combined with multiple trauma by judging injury severity quickly and precisely based on the principle of "life first" and repeated and systemic physical examination.

BACKGROUND:A large number of articles have reported the effect and mechanism of platelet-rich plasma and hydrogel in the treatment of spinal cord injury,but few articles have summarized their treatment strategies for spinal cord injury. OBJECTIVE:To summarize the pathological process of spinal cord injury and the strategies of repairing spinal cord injury with platelet-rich plasma and hydrogel alone and in combination. METHODS:PubMed and CNKI databases were searched for articles published from inception to March 2024 by computer.The Chinese search terms were"spinal cord injury,platelet-rich plasma,hydrogel."The English search terms were"spinal cord injury,spinal cord,platelet-rich plasma,hydrogel,angiogenesis,neuralgia,combination therapy."Articles were screened according to inclusion and exclusion criteria,and 128 articles were finally included for review and analysis. RESULTS AND CONCLUSION:(1)The classification of platelet-rich plasma is complex and diverse,and the effects of platelet-rich plasma in the repair treatment of spinal cord injury are various,but they all show certain positive effects,that is,they can promote axon regeneration,stimulate angiogenesis,and treat neuropathic pain and so on.(2)The effect of platelet-rich plasma is mainly due to the growth factors contained in platelet-rich plasma.(3)There are many types of hydrogels,which mainly play the role of filling,simulating extracellular matrix,carrying drugs and biological products,and carrying cells as scaffolds in the repair treatment of spinal cord injury.(4)Compared with single therapy,combination therapy of platelet-rich plasma and hydrogel can promote nerve regeneration and spinal cord function recovery more effectively.

Objective:To analyze the impact of cecal ligation and puncture (CLP)-induced sepsis on the proliferation and differentiation of intestinal epithelial cells.Methods:① Animal experiment: sixteen male C57BL/6 mice were divided into sham operation group (Sham group) and CLP-induced sepsis model group (CLP group) by random number table method, with 8 mice in each group. After 5 days of operation, the jejunal tissues were taken for determination of leucine-rich-repeat-containing G-protein-coupled receptor 5 (LGR5) and intestinal alkaline phosphatase (IAP) by polymerase chain reaction (PCR). The translation of LGR5 was detected by Western blotting. The expression of proliferating cell nuclear antigen (Ki67) was analyzed by immunohistochemistry. IAP level was detected by modified calcium cobalt staining and colorimetry. Immunofluorescence staining was used to detect the expression of Paneth cell marker molecule lysozyme 1 (LYZ1) and goblet cell marker molecule mucin 2 (MUC2). ② Cell experiment: IEC6 cells in logarithmic growth stage were divided into blank control group and lipopolysaccharide (LPS) group (LPS 5 μg/mL). Twenty-four hours after treatment, PCR and Western blotting were used to analyze the transcription and translation of LGR5. The proliferation of IEC6 cells were detected by 5-ethynyl-2'-deoxyuridine (EdU) staining. The transcription and translation of IAP were detected by PCR and colorimetric method respectively.Results:① Animal experiment: the immunohistochemical results showed that the positive rate of Ki67 staining in the jejunal tissue of CLP group was lower than that of Sham group [(41.7±2.5)% vs. (48.7±1.4)%, P = 0.01]. PCR and Western blotting results showed that there were no statistical differences in the mRNA and protein expressions of LGR5 in the jejunal tissue between the CLP group and Sham group (Lgr5 mRNA: 0.7±0.1 vs. 1.0±0.2, P = 0.11; LGR5/β-actin: 0.83±0.17 vs. 0.68±0.19, P = 0.24). The mRNA (0.4±0.1 vs. 1.0±0.1, P < 0.01) and protein (U/g: 47.3±6.0 vs. 73.1±15.3, P < 0.01) levels of IAP in the jejunal tissue were lower in CLP group. Immunofluorescence saining analysis showed that the expressions of LYZ1 and MUC2 in the CLP group were lower than those in the Sham group. ②Cell experiment: PCR and Western blotting results showed that there was no significant difference in the expression of LGR5 between the LPS group and the blank control group (Lgr5 mRNA: 0.9±0.1 vs. 1.0±0.2, P = 0.33; LGR5/β-actin: 0.71±0.18 vs. 0.69±0.04, P = 0.81). The proliferation rate of IEC6 cells in the LPS group was lower than that in the blank control group, but there was no significant difference [positivity rate of EdU: (40.5±3.8)% vs. (46.5±3.6)%, P = 0.11]. The mRNA (0.5±0.1 vs. 1.0±0.2, P < 0.01) and protein (U/g: 15.0±4.0 vs. 41.2±10.4, P < 0.01) of IAP in the LPS group were lower than those in the blank control group. Conclusion:CLP-induced sepsis inhibits the proliferation and differentiation of intestinal epithelial cells, impairing the self-renewal ability of intestinal epithelium.

【Objective】 To summarize a rapid and effective method to eliminate autoantibodies interference with blood group identification and evaluate its treatment effect. 【Methods】 Blood samples with suspicious results in initial blood group identification were collected, and those caused by autoantibodies were chosen, and their red blood cells were washed, dispersed or treated with sulfhydryl reagent. After allogeneic or autologous absorption of plasma, blood groups of those patients were re-detected to evaluate the effectiveness of the above method. 【Results】 Among 39 patients presenting suspicious ABO blood group, 9 were interfered by autoantibodies. After appropriate treatment, the ABO/RhD blood group of those patients could be identified. 【Conclusion】 Autoantibodies could interfere the identification of ABO/RhD blood group, and the efficiency and accuracy of blood group identification could be improved by analyzing the test results and selecting appropriate treatment methods.
