Chinese Journal of Rehabilitation Theory and Practice 2003;9(8):494-495
目的观察促进截瘫患者不良情绪转化的相关因素。方法对86例住院截瘫患者进行日常生活能力评定和焦虑、抑郁量表评定,根据评定结果制定康复训练计划,同时开展心理护理;3个月后进行第2次评定。结果约80%的入院患者有不同程度的焦虑和抑郁情绪,经康复训练和心理护理后,患者的焦虑和抑郁情绪均有不同程度减轻。此外,焦虑及抑郁情绪的轻重与病程长短无关(P>0.05),可促进截瘫患者不良情绪转化的相关因素为适宜的环境、日常生活能力提高、良好的心理护理和及时有效的健康教育。结论了解促进截瘫患者不良情绪转化的相关因素有助于有针对性地对患者实施心理护理,有利于患者回归家庭、回归社会。
5.Effects ot VEGF-165 gene therapy on apoptosis in brain traumatic injury
Chinese Journal of Emergency Medicine 2009;18(4):367-371
Objective To study the changes of apoptosis in brain after traumatic injury(TBI)treated with exogenous vascular endothelial growth factor(VEGF)gene therapy in oder to find out the role of exogenous VEGF gene in protectiog brain tissue.Method The injurea cerebral cortex from the rat models of brain with traumatic injury was injected with adenovirus(adenovirus,Ad)as the carrier of VEGF-165 gene(Ad-VEGF-165 Gene).RT-PCR and Western blot were used to detect the expression of VEGF mRNA and VEGF protein in the brain 6 h,24 h,3 d,7 d and 14 d after injury,and apoptosis in the injured location of brain was also detected by TUNEL successively after Ad-VECF-165 gene therapy.Results With exogenous Ad-VEGF-165 applied to the locally injured brain tissue after injury,VEGF mRNA and VEGF protein showed consistent expression and their expressions were significantly higher than those in trauma group and vehicle control group.Compared with the trauma group.the apoptosis in the gene therapy group 24 h,3 d and 7 d after injury presented a.significant reduction,and had close relationship with VEGF.(Control group:4.17±0.73;TBI group,24 h:47.18±6.01,3 d:79.44±11.23;TBI+VEGF group.24 h:28.72±5.31,3 d:54.18±7.66;P<0.05).Conclusions The exogenous VEGF gene therapy administered to have protective effects on the local brain tissue in rats with traumatic injury in a certain time.
6.In vivo animal models of cerebral vasospasm following subarachnoid hemorrhage
International Journal of Cerebrovascular Diseases 2010;18(6):477-480
Delayed cerebral vasospasm is the leading cause of death in patients with subarachnoid hemorrhage. A good in vivo animal model of cerebral vasospasm after subarachnoid hemorrhage helps to understand the occurrence, development of this cerebral vasospasm, and the complicated and various pathophysiological mechanisms. It will provide important information for clinical interventions
7.Analysis in effect of intermittent pneumatic compression pump to prevent deep venous thrombosis for patients after hip surgery
Chinese Journal of Practical Nursing 2010;26(15):6-7
Objective To observe the therapeutic effect of intermittent pneumatic compression pump to prevent deep venous thrombosis for patients after hip surgery. Methods A total of 104 bedridden patients 72 hours after hip surgery were divided into the treatment group and the control group. Patients in the control group were administrated routine antithrombotic drugs and active functional exercise. While patients in the treatment group were provided with intermittent pneumatic compression pump as assistant based on the routine treatment and active functional exercise. The condition of deep venous thrombosis in the two groups were observed. Results Intermittent pneumatic compression pump had remarkable therapeutic effect on preventing deep venous thrombosis of lower extremity for patients lying in bed over 72 hours after hip surgery. Conclusions Intermittent pneumatic compression pump as an assistant treat -ment based on the routine antithrombotic therapy contributes to prevent deep venous thrombosis of lower extremity for patients lying in bed over 72 hours after hip surgery.

9.Value of contrast -enhanced ultrasound in evaluating peripancreatic vascular invasion and resectability of pancreatic cancer
Journal of Clinical Hepatology 2017;33(1):126-129
Objective To investigate the value of preoperative contrast -enhanced ultrasound (CEUS)in evaluating peripancreatic vascular invasion and resectability of pancreatic cancer.Methods A retrospective analysis was performed for the clinical data of 25 patients with pancreatic cancer confirmed by surgical exploration or postoperative pathological examination,who visited Shengjing Hospital of China Medi-cal University from December 2012 to October 2014,and all the patients underwent CEUS before surgery.The relationship between the le-sion and the peripancreatic vessels was observed,the degree of invasion was evaluated,and related scores were measured.These results were compared with the results of intraoperative exploration and postoperative pathological results.The rate of peripancreatic vascular invasion, sensitivity and specificity of preoperative CEUS in evaluating the degree of peripancreatic vascular invasion,and sensitivity,specificity,pos-itive predictive value,negative predictive value,overall coincidence rate,and Youden index of CEUS in evaluating the resectability of pan-creatic cancer were calculated.Results Preoperative CEUS showed that 42 vessels were invaded,while intraoperative exploration showed 41 vessels were invaded.A total of 17 patients were considered resectable by CEUS,while 15 patients were considered resectable by intraop-erative exploration.In evaluating the resectability of pancreatic cancer,CEUS had a sensitivity of 93.3%,a specificity of 70.0%,an over-all coincidence rate of 84.0%,a false positive rate of 30.0%,a false negative rate of 6.7%,a positive predictive value of 82.4%,a nega-tive predictive value of 87.5%,and a Youden index of 0.633.Conclusion Compared with intraoperative exploration,CEUS has higher sensitivity and specificity in evaluating the degree of peripancreatic vascular invasion and higher sensitivity,specificity,and coincidence rate in evaluating the resectability of pancreatic cancer.CEUS can accurately evaluate the degree of peripancreatic vascular invasion and provides a new method for preoperative evaluation of the resectability of pancreatic cancer.
10.The immune status of pancreatic cancer patients
Journal of International Oncology 2016;43(3):223-225
During the development of pancreatic cancer,the local and whole immune state of the patients is constantly changing,and through which the cancer cells escape from the immune attack.The main immunologic mechanism includes the induction of tumor immune suppression cells and producing the related cytokines.The changes of the whole immune status include the increase of immunosuppressive cells,the change of the immune function of T cell subsets and the inhibition of natural killers and lymphokine activated killer cells.In the local tumor,the infiltrating lymphocytes loss the function,and the ratio of Thl/Th2 cytokines is imbalance.
