The value balance of Zhuangzi inclines to the other shore of life.Meanwhile,it needs to grasp firmly the reality.Therefore,it is important to adjust to the real life.In this thesis,life,which is based on the sense of semantics,is taken as the starting point,and life and fate are analyzed in the sense of life ethics from the four levels of(parents) command,fate,mandate of heaven and life.On the static aspect,it can evolve the problem on the beginning and end in Zhuangzi's life ethics.In Zhuangzi's viewpoint,living complies with time and death is conforming.Life and death are the same and identical.On the dynamic aspect,it is eternal.In Zhuangzi's concept coordinate of the identity of life and death,the idea of helping settle down the feeling of life is put forward and it forms the life model of self-changing and self-living.Following the logic clue,a reflection on Zhuangzi's life philosophy is developed and shows his life philosophy model that "I think,therefore,I not exist".

BACKGROUND:Currently thoracolumbar fixation techniques have its advantages and disadvantages, it is necessary to explore a new internal fixation to fix the spine effectively and conveniently.
OBJECTIVE:To establish thoracolumbar (T12-L2) three-dimensional finite element model and observe the effect of anteroposterior integration fixation by posterolateral nail-stick system on thoracolumbar stability.
METHODBased on the CT scan data of normal human T12-L2 segments, we used Geomagic 11.0, Ug 7.0, Hypermesh 10.0, Abaqus 6.9.1 software to establish a three-dimensional finite element model of T12-L2 segments. Subsequently we established nail-stick system posterior fixation, anterior fixation, posterolateral anteroposterior integration fixation model. T12 segment was given 500 N preload and 7.5 N·m torque, to simulate thoracolumbar flexion, extension, lateral bending and rotation. The average rigidity of fixed segments under different conditions were observed.
RESULTS AND CONCLUSION:Three fixation models showed a higher average rigidity than normal model under different conditions. The average rigidity in anteroposterior integration fixation by posterolateral nail-stick system was increased by 13%, 28%, 11%, 17%and 9%, compared with simple posterior fixation under the conditions such as anterior flexion, lateral bending and lateral rotation, respectively. Under the posterior extension, the average rigidity was reduced by 6%than the posterior fixation. Compared with the anterior fixation, the average rigidity in anteroposterior integration fixation by posterolateral nail-stick system was reduced by 15%, 10%, and 14%under the conditions of anterior flexion and lateral bending. While the average rigidity was higher than anterior flexion under the posterior extension and lateral rotation, increasing 5%, 12%and 2%. The anteroposterior integration fixation by posterolateral nail-stick system can improve the stability of fixed segments, and the stability is higher than anterior fixation at posterior extension and lateral rotation, while higher than posterior fixation in anterior flexion, lateral bending and lateral rotation. So it is a potential fixation method.

Objective To evaluate the diagnostic value of the combination of serum DKK1 (Dickkopf-1 )and P53 autoantibodies in patients with esophageal squamous cell carcinoma (ESCC).Methods Serum levels of DKK1 and P53 autoantibodies were measured by enzyme-linked immunosorbent assay (ELISA) for the 1 26 patients with ESCC and 60 normal controls.Receiver operating characteristics (ROC)was used to calculate the diagnostic efficiency.Results The serum levels of DKK1 and P53 autoantibodies were signifi-cantly higher in ESCC than those in normal controls [(673.09 ±343.82)pg/ml vs (362.05 ±1 48.07)pg/ml, Z =6.1 58,P <0.000 1 ;(0.398 ±0.546)vs (0.069 ±0.050),Z =3.832,P <0.000 1 ].ROC curves showed the optimum diagnostic cutoff for serum DKK1 was 588.77 pg/ml,with an area under curve (AUC)of 0.780 (95%CI:0.71 5 ~0.844,61 .9% sensitivity,95.0% specificity).Measurement of P53 autoantibodies demonstrated an AUC of 0.674 (95%CI:0.598 ~0.750,45.3% sensitivity,95.0% specificity).The com-bination of DKK1 and P53 autoantibodies yielded an AUC of 0.843 (95%CI:0.788 ~0.897,73.8% sensitiv-ity,95.0% specificity).In early-stage ESCC,combined detection of DKK1 and P53 autoantibodies improved the diagnostic power,with an AUC of 0.903 (95%CI:0.845 ~0.961 ,81 .0% sensitivity,95.0% specifici-ty).Conclusion Serum DKK1 and P53 autoantibodies can be used as potential diagnostic biomarkers for the ESCC.Combined detection of them might aid the early diagnosis of ESCC.

BACKGROUND:In elderly patients with unstable intertrochanteric fracture, because of poor general condition and poor bone condition, on one hand, the internal fixation of fracture may lead to nonunion. On the other hand, patients stil need longer time in bed and hip joint fixation, and may result in complications of long-term bed rest. Artificial femoral head replacement is a safe operation mode, can solve the problem of early ambulation of patients. OBJECTIVE:To observe the repair effect of bipolar artificial femoral head replacement on unstable femoral intertrochanteric fracture in elderly patients. METHODS: A total of 39 elderly patients with unstable femoral intertrochanteric fractures, who were treated in the Department of Orthopedics, 101 Hospital of Chinese PLA from 2005 to 2014, were enroled in this study. There were 21 males and 18 females, at the age of 80-96 years old, averagely 85 years old. They al received bipolar artificial femoral head replacement. Harris score was measured to assess hip joint function at 1 year after replacement. The incidence of complications was recorded. RESULTS AND CONCLUSION:A total of 39 cases were folowed up for 1-5 years. The wound of al patients was healed in the primary stage. No cardiovascular or cerebrovascular accident appeared. Al patients passed safely through the perioperative period. No severe complications occurred. Hip joint function was assessed according to Harris score at 1 year after replacement: excelent in 13 cases, good in 20 cases, average in 4 cases, poor in 2 cases, with an excelent and good rate of 85%. No dislocation appeared. The results suggest that bipolar artificial femoral head replacement can be used to treat femoral intertrochanteric fracture in elderly patients. The postoperative recovery time was short; bleeding was less; complications were few. Hip joint function recovered wel. For elderly patients with femoral intertrochanteric fracture, bipolar artificial femoral head replacement is an ideal safe effective repair method.

BACKGROUND:Posterior hip dislocation combined with femoral head fractures easily induced femoral head necrosis, ectopic ossification, osteoarthritis and deep vein thrombosis. Different therapeutic methods should be utilized according to the type of fracture.
OBJECTIVE:To investigate the factors affecting the therapeutic effects and complications fol owing surgery of posterior hip dislocation combined with femoral head fractures.
METHODS:Twenty-eight patients, who had been diagnosed as posterior hip dislocation combined with femoral head fractures in the 101 Hospital of Chinese PLA from September 2004 to May 2010, were enrol ed in this study. According to Pipkin typing, operative approach and the time from injury to surgery, therapeutic effects were evaluated using radiographs and the recovery conditions of hip function (Epstein method), and the occurrence of complications was recorded.
RESULTS AND CONCLUSION:A total of 28 patients were fol owed up from 1 to 5 years, averagely 2.8 years. Using the Epstein method, there were excellent in 6 cases, good in 12 cases, average in 7 cases, and poor in 3 cases, with an excellent and good rate of 64%. The therapeutic effects in patients with Pipkin I and II were good, with excellent and good rates of 100%and 78%, respectively. Moreover, the complications were less, with a rate of 17%and 22%, respectively. The therapeutic effects of patients with Pipkin III and IV were poor, especial y, Pipkin IV patients, whose excellent and good rate was only 20%and the incidence of complications was 80%. No significant difference in the incidence of complications was detected in patients undergoing Smith-Peterson anterior approach and K-L posterior approach (P>0.05). No significant difference in the incidence of complications was detectable among patients from three groups (the time from fracture to operation<12 hours, 12-48 hours, and>48 hours) (P>0.05). Results indicated that the choice of treatment method should be determined by the type of fracture. The prognosis depends on the patient’s age, time of treatment, types of fracture and dislocation, methods of treatment and related measures of prevention of complications.

Objective: To explore the effect of CO 2 pneumoperitoneum in laparoscopic surgery on the cardiovascular function of the geriatric cholelithiasis.Methods:Sixty aged patients undergone laparoscopic surgery were selected.During various stage of CO 2 insufflation,the heart rate(HR),blood pressure,oxygen saturation ,electrocardiogram(ECG),and myocardial enzymes were dected,and the clinical values of these changes were analyzed.Results: when CO 2 pneumoperitoneum established ,the HR and blood pressure were increased obviously .The incidence of arrhythmia was 36% and the incidence of changes of ST segment was 30%,10 minutes after pneumoperitoneum eliminated,these changes were restored. The myocardial enzymes and the oxygon saturation of blood had no distinct changes. Conclusion: The procedure of CO 2 pneumoperitoneum caused temporany changes of the HR ,SBP/DSP and ECG.The laparoscopic surgery is effective and safe for geriatric cholelithiasis.It suggests that the dynamic monitoring of electrocardiogram is necessary,especially for those with abnormal heart function.

To determine the effect of pre-operative chemotherapy on apoptosis in breast cancer and to evaluate its signif icance as a prcgnostic marker. MethodsPatients with breast cancer were divided into preoperative chemotherapy group (40 cases)and control group (42 cases). Two groups were analyzed for the appearance of apoptosis by using TUNEL method and electron mi croscope in tissue sections. ResultsApoptosis occurred in 92.5 % of preoperative chemotherapy group and in 78.5 % of control group. The apoptotic indexes were 19.37 + 6.49 and 9.26 + 5.04 ( P ＜ 0.01 ) respectively. Low apoptotic index was related to disease-free survival of patients with breast cancer (P ＜ 0.01 ). ConclusionThe preoperative chemotherapy can induce apoptcsis of breast cancer and improve disease-free survival.
