The spirit of contract, with freedom, equality and reciprocity of power and responsibility as basic connotation and containing credit consciousness, is the core content of the concept of rule of law. People′s desire for justice, recognition of fairness, reliance on integrity contained in the concept of rule of law all originate from the spirit of contract, such as contract party's expectation of fairness, performance of obligation, abiding by the valid contract. Not only does the concept of rule of law reflect the essence requirement of the spirit of contract, but also is the external form of realization. Therefore, in order to enhance the concept of rule of law of the college students, it is a certain choice to cultivate the spirit of contract. However, the current paths to cultivate the spirit of contract are mainly theoretical research, environmental influence and system perfection.

Objective:To evaluate the value of color Doppler ultrasound combined with ultrasonic elastography for curative effect of neoadjuvant chemotherapy (NAC) for breast cancer.Methods: 100 patients with breast cancer who has received NAC were divided intoobservation group (50 cases, underwent examination of color Doppler ultrasound scanner combined with ultrasonic elastography) and control group (50 cases, only underwent examination of color Doppler ultrasound scanner) according to the different examination methods. The accuracy, sensitivity and specificity of differential diagnosis methods for curative effect of NAC between the two groups were compared as above data.Results: The accuracy, sensitivity and specificity of differential diagnosis for curative effect of NAC in observation group were 88.00％, 90.00％ and 86.00％, respectively. While them of control group were 78.00％, 80.00％ and 76.00％, respectively. And the differences of these indicators between the two groups were statistically significant (x2=2.01,x2=3.24,x2=3.45, P<0.05).Conclusions: Color Doppler ultrasound combined with ultrasound elastography can diagnose the curative effect of NAC for patients with breast cancer from two aspects which includes tissue hardness and blood supply, and it can achieve more diagnostic accuracy compared with only using simple color Doppler ultrasound.

Objective To study the clinical and image features of the aortic dissecting aneurysm(AD) combined with aberrant right subclavian arteries(ARSA),and to discuss the feasibility of endovascular repair for such disorder.Methods The clinical and image data of 4 patients,who suffered from AD combined with ARSA and admitted in the authors' service during 2004 to 2007,were retrospectively reviewed.All the 4 cases complained severe aches in their back,and one of them was companied with aches in upper abdomen.CT-exam showed that the first tear(gap) of AD located near or inside ARSA,the truncus aortae narrowed obviously.Four operational prescriptions were performed respectively for the 4 patients depending on the location of gaps and on the distance between the gap and ARSA.Results All the 4 cases received satisfy operation.A slight early leakage occurred in the first case without steal syndrome,and the lower blood pressure was 80 mmHg on right arm;for the second case,no leakage occurred with normal blood presser on both arms;for the third one a slight early leakage was companied with normal blood presser on both arms and for the fourth one a slight early leakage occurred without steal syndrome,and the lower blood presser was 60mmHg on right arm.Conclusion AD combined with ARSA is a rare case in clinic.The modus operandi of endovascular repair should be designed based on the situation of individual case considering the location of the first tear.Once the target area exposed is not wide enough for operation,subclavian artery bypass would be a right way in reduction of leakage complications and in increasing the opportunity for a successful operation.

Objective To observe the pharmacological effect of Jiaweisinisan (JWSNS) on alcohol liver diseases. Methods Feeding Wistar rats with alcohol induced the alcohol liver diseases model. Then JWSNS was used on the alcohol liver diseases model to observe the histological variation of liver and detect the effect on the liver’s expression of SOD, GSH-PX, CAT and MDA. At the same time, Xiaochaihu granule group was used as control. Results On the alcohol liver diseases model group processed with JWSNS, obvious decrease of pathological injury with expression of MDA in liver was observed, while a markedly increased expression of SOD, GSH-PX and CAT was detected. Conclusions JWSNS can prevent liver cells from peroxided injury by alcohol.

Objective To observe the clinical effect of Jiawei Sinisan (JWSNS) on patients with alcohol liver diseases. Methods 80 patients of alcohol liver diseases were divided into two groups, JWSNS and Xiaochaihu (as control) were used respectively to observe the variation of lipoprotein and the expression of hepatic fibrosis markers. Results The symptoms and indicators of patients were improved by JWSNS. The high variation of lipoprotein and the expression of hepatic fibrosis markers were obviously detected on alcohol liver diseases patients who were treated with JWSNS (with an effectivity of 97.5%). However, patients treated with Xiaochaihu had less therapeutic effect. Conclusions JWSNS can obviously regulate the fat metabolism, resist hepatic fibrosis, and improve the symptom of patients suffering from alcohol liver diseases.

The biochemical and other lab indices of blood in 35 cases of nephrosis syndrome (NS) treated with Huangqi Xianlingpi Decoction plus Hirudo (HQXL) were observed. The results that HQXL was capable of decreasing urine protein, increasing plasma protein, lowering blood lipids (P

Objective To evaluate the role of oxidative stress in the spinal neurotoxicity induced by ropivacaine in rats.Methods Ninety pathogen-free male Sprague-Dawley rats,weighing 250-320 g,aged 3 months,in which intrathecal catheter was successfully implanted into L5,6 interspace without complications,were randomly divided into 3 groups (n =30 each) using a random number table:control group (group C),ropivacaine group (group R),and antioxidant Tempol group (group T).The rats received 1％ ropivacaine 1.2 μg/g for 8 times at 1.5 h intervals through the catheter in R and T groups,while the rats received the equal volume of normal saline instead in group C.In T group,Tempol 20 μg/g was injected intrathecally at 4,8,12,24,48 and 72 h after the last injection of ropivacaine.The rats were sacrificed at 1,3,5,7 and 14 days after the end of ropivacaine injection,and their lumbar enlargements were removed for TUNEL staining to detect the cell apoptosis.SOD activity was determined by colorimetry and MDA content was measured using TBA photoelectric colorimetry.Apoptosis index was calculated.Results Compared with group C,apoptosis index and MDA content were significantly increased,and SOD activity was decreased in R and T groups.Compared with group R,apoptosis index and MDA content were significantly decreased,and SOD activity was increased in group T.Conclusion Oxidative stress is involved in the development of spinal neurotoxicity induced by ropivacaine in rats.

Objective To explore the application effect of cognitive behavioral intervention on chronic obstructive pulmonary disease nursing care.Methods 80 patients with chronic obstructive pulmonary disease were randomly divided into an experimental group and a control group(n=40).Both groups were given medical treatment and conventional nursing care,and the control group was given the cognitive behavioral intervention nursing care additionally.The average days of stay,the ratio of readmission,the treatment adherence,and smoking cessation rate in one year were recorded.Moreover,the life quality of the two groups was analyzed with a CAT assessment test.Results Compared with the control group,the experimental group achieved shorter average days of stay,higher medication adherence and smoking cessation rate,lower readmission rate and admission rate.The experimental group achieved better life quality with lower CAT value than the control group.Conclusion Cognitive behavioral intervention can obviously improve the treatment effectiveness of patients with chronic obstructive pulmonarv disease.

Objective To analyze the reasons and mechanisms of stereoscopic function abnormality in elder patients after the cataract extraction with intraocular lens implantation. Methods 150 cases with artificial lens implantation were randomly selected.Routine eye examinations were carried out and the associated refractive error and presbyopia were corrected.Bilateral simultaneous visual perception and fusion function were examined.The stereoscopic function was tested using "the stereoscopic function examination diagram"created by Yan Shao-ming.Ninety-seven patients who were found to have unrecover-ed or abnormal stereoscopic function were enrolled for analysis. Results In these 97 cases,53(54.6%)were found to have preexisting eye disorders that could affect visual acuity and binocular single vision before the operation.Macular problem was the most prevalent problem in this group.Twenty-seven(27.8%)patients had complicated with corneal astigmatism,after cataract,paralysing strabismus and diplopia as well as macular edema after the operation.In addition,the contralateral unoperated cataract in 17(17.5%)patients and post-operative anisometropia in 9(9.3%)patients were also the causes of stereoscopic function abnormality.There was no reason could be identified in 8 cases. Conclusions The pre-existing eye disorders before lenses implantation,complications of the operation,contralateral unoperated cataract and anisometropia are all the major factors that affect visual acuity recovery and bilateral stereoscopic function rehabilitation.
