Objective To establish the Sprague-Dawley rats psychological stress model and investigate the effect of the psychological stress on behavior and condylar cartilage of Sprague-Dawley rats. Methods Sprague-Dawley rats were randomly divided equally into psychological stress group, foot shock group and control group, and the foot shock group was only as sources of stimuli. The Sprague-Dawley rats psychological stress model was built, and the rats were killed at 1, 3 and 5 weeks respectively after stimulation. The behavior changes were observed by open field test,etc. The histology of condylar cartilage was observed by HE stain. Results Psychological stress model was effective in evaluating behavior changes. The pathological examination revealed structural changes of the condylar cartilage in the psychological stress group. The psychological stress groupⅡwas the most serious group with collagenous fibers disintegrated and gaps formed. Conclusion This rats model of the psychological stress shows great practicability and reproducibility. The long-term psychological stress can lead to SD rats behavior changes and temporomandibular joint condylar cartilage change.

Objective To observe rehabilitation and functional prognosis of patients suffered from brain infarction of acute phase complicated by depression. Method We selected 38 cases of acute brain infarct complicated with depression disorder as depression group, 40 cases of non－ depression patient admitted at the same period were selected as non depression group.Antidepressants drugs administration and rehabilitation therapy were performed.We evaluated patients according to functional independence measure(FIM)of Chinese edition. HAMD grading comparison was carried out in depression group. Result Before treatment,two groups score nearly the same,compared with pretreatment. After treatment,patients in depression group and non depression group showed significant improvement esp non－ depression group (P<0.01).11 cases with severe depression in the depression showed no changes in FIM score before and after treatment. Conclusion Compared with non－ depression patients,functional recovery of patients with depression following brain infarction of acute stage is much slower,especially for patients with severe depression.

Objective To explore the lean management model for the application of National Natural Science Foundation of China (NSFC).Methods Under the framework of lean management,Peking University Third Hospital (PUTH) tapped potential through the earlier stage survey and policy guidance,focused on improving efficiency based on discipline and talent,curriculum service were also provided to bolster application quality.This paper reviewed the NSFC application situation of PUTH in 2014 2016 and compared with 2011-2013,summarized the management experience.Results All the indexes increased significantly during 2014-2016,also achieved a breakthrough in talent projects.Compared with 2011 2013,the application number of 2014-2016 increased by 34.8％,meanwhile,both the support number and amount of NSFC increased 44.2％ and 111.6 ％ respectively.We also achieved 71.8％ growth and added 5 experts in high end talent projects.Conclusions The lean management significantly improves the management efficiency,and we hope to make reference to other clinical hospitals in promoting basic research management.

OBJECTIVE:To explore the effects of Kangfuxin liquid combined with Oral ulcer powder on inflammatory cyto-kines and therapeutic efficacy of recurrent aphthous ulcer. METHODS:134 patients with recurrent aphthous ulcer were randomly divided into observation group and control group,with 67 cases in each group. Both groups received routine treatment;control group was additionally given Oral ulcer powder,q2 h;observation group was additionally given Kangfuxin liquid,10 ml/time,gar-gling for 5-10 min and then swallowing slowly,tid. Treatment course of 2 groups lasted for 7 d. Clinical symptoms,serum inflam-matory cytokines,clinical symptom improvement and recurrence were observed in 2 groups. RESULTS:Total effective rate of ob-servation group was 95.52%,which was significantly higher than that of control group(82.09%),with statistical significance(P<0.05). The levels of TNF-α,IL-1 and IL-6 in observation group were significantly lower than those of control group,with statisti-cal significance(P<0.05);ulcer duration and VAS score of observation group were significantly shorter or lower than those of con-trol group,with statistical significance(P<0.05);after followed up for 6 months,recurrence rate of observation group(11.94%) was significantly lower than that of control group(31.34%),with statistical significance(P<0.05). CONCLUSIONS:Kangfuxin liquid combined with Oral ulcer powder helps to lower levels of inflammatory cytokines of patients with recurrent aphthous ulcer, relieve the clinical symptoms,then improve therapeutic efficacy and reduce recurrence rate.

Objective To evaluate the safety of mesohepatectomy for centrally located large hepatic tumors.Methods The clinical data of 37 patients who underwent hepatectomy for centrally located large liver tumors in our hospital from October 2010 to August 2015 were retrospectively analyzed.During the operation,the left and right hemilivers were mobilized.Slings for the improved liver hanging maneuver and for selective hepatic vascular occlusion were placed.These slings were used when necessary in order to minimize occlusion and ischemia time to the residual liver,and to maximize the volume of functional liver remnant.Mesohepatectomy was carried out using a microwave hemostatic separator.The feasibility,its effects on preventing hemorrhage,the degree of liver damage and the postoperative complications were evaluated.Results The mean diameter of the neoplasms was (12.6 ± 7.2) cm.The vascular inflow occlusion time of the left and right hemilivers were (12.2 ±3.5) min and (18.5 ±7.1) min,respectively.The blood loss was (487 ± 352) ml.The amount of red blood cell transfusion was (2.7 ± 1.9) U.The operation time was (215 ± 72) min.TBIL,ALT and AST reached their peak levels on the 1 st day after operation and they were higher than before surgery (P ＜ 0.01).The levels were then significantly decreased on the 3rd day after operation.However,the TBIL (P ＜ 0.05),ALT (P ＜ 0.01) and AST (P ＜ 0.05) were higher than the preoperative level,and only returned to normal or were close to the preoperative value on the 7th day after operation (P ＞ 0.05).The initial increase in ALT was quick and then it slowed down,while the initial increase in AST was slow but it decreased quickly.Conclusions Mesohepatectomy for centrally located large hepatic tumors could safely be carried out using the liver hanging maneuver combined with selective hepatic vascular occlusion and a microwave hemostatic separator.This method has the advantages of causing less bleeding,liver damage and rapid recovery.

Objective:To explore the diagnostic value of color Doppler echocardiography for cardiac tumors .Meth-ods:Clinical data of 87 patients with cardiac tumors were retrospectively analyzed ,including their diseased loca-tion ,clinical manif′estations and echocardiography feature .Results:All cardiac tumors obtain pathologic confirma-tion .There were 73 patients (83.9% ) with benign cardiac tumors ,including 66 patients (90.4% ) with myxoma and seven patients with other types ;there were 14 patients (16.1% ) with malignant cardiac tumors .Echocardiography indicated that myxoma was often located in left atrium (n=58) ,most cases possessed pedicell,its activity was large ;Other type benign cardiac tumors feature :The 6 case (86% ) were generated inside cardiac muscle without pedicell, its echo was more strong ;malignant tumors:its attachment surface was wide without pedicell,and it may show with globular or cauliflower ,and accompanied hydropericardium mostly .Conclusion:Echocardiography can dynamically observe the form ,size ,echo and hemodynamic changes of tumors ,its diagnostic accuracy is high .Myxoma is most frequent cardiac tumor .
