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.

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 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 explore the influence of stereoscopic vision on the development of posterior capsule opacification (PCO) after intraocular lens implantation. The efficacy of Nd: YAG laser was studied. Design Case-controlled study. Participants 57 consecutive patients with POC(59 eyes with phacoemulsification and IOL implantation). Methods A prospective observational study was conducted comprising 57 patients (59 eyes) who had postoperative PCO. Neodymium: YAG (Nd: YAG) laser posterior capsulatomy was performed on all patients following a standardizes procedure. Preoperative and postoperative evaluation included LogMAR visual acuity, best-corrected visual acuity (BCVA), contrast sensitivity and stereoscopic vision. Main Outcome Measures LogMAR visual acuity, BCVA, contrast sensitivity and stereoscopic vision. Results The average LogMAR eyesight median of sick eye before laser treatment was (0.22?0.31) and the contrast sensitive degree of each frequency area was relatively lower than the opposite eye; After the treatment, there was evident improvement of the sick eye, and the LogMAR eyesight median of that was 0.00; The ratio of reaching the central spatial eyesight and the average sharpness degree both improve much than ahead of treatment. Those whose spatial eyesight sharpness don't get normal after the low best remedy eyesight. Irregular dipodic and previous eye disease. Conclusions LogMAR visual acuity, BCVA, contrast sensitivity and stereoscopic vision were damaged markedly with PCO. Our results indicate that Nd: YAG capsulotomy may affect the reconstruction of stereoscopic vision. Nd:YAG laser posterior capsulotomy is a valuable and clinically relevant method for clinical treatment of PCO.

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 summarize our experiences of management for hypogastric artery in endovascular repair(EVR) of infrarenal abdominal aortic aneurysm(IAAA).Methods From July,1997 to March,2007,62 cases of IAAAs required special management of the internal iliac artery(IIA) during the EVR.Among them,57 cases were type C AAA who included 35 cases of unilateral common iliac artery(CIA) bifurcations and 22 cases of bilateral iliac bifurcations.The remaining 5 cases involved superior iliac bifurcations.Various techniques including simple coverage by stent-graft,embolization of the IIA trunk combined with stent-graft covering,reconstruction of the IIA and combination of the above techniques were applied according to the different conditions of the IIA involved.Results None of the 62 patients required conversion to surgical repair.Immediate post operational angiography demonstrated type Ⅰ endoleak in 6 cases(9.7%).Claudication due to gluteus ischemia occurred in 5 cases(8.1%),leg numbness in 1 case(1.6%),and severe constipation in 1 case(1.6%),but no buttock and colorectal necrosis was recorded.Conclusion It is important to preserve one of the hypogastric arteries and avoid occlusion of both hypogastric arteries in EVR of IAAA.

Objective To evaluate the efficacy of endovascular aortouniiliac repair (EVAR) combined with cross-femoral bypass grafting (CFBG) for the treatment of abdominal aortic aneurysm (AAA). Methods From May 1997 to February 2007, 8 patients with AAA, in whom bifurcated stent-graft could not be used because of complex iliac anatomy, were treated with EVAR using AUI stent-graft combined with CFBG. The endoleak, ischemic syndromes,patency of the bypasses, and blood supply of the lower limbs were observed after the operation. Results There were no perioperative mortalities in this series. One patient died of myocardial infarction 15 months after the operation. Three patients developed primary endoleak, and was cure spontaneously 1, 3, and 6 months postoperation. The 8 patients were followed up for a mean of 24 months (3-72 months), during which the patency rate of cross-femoral bypass was 100%. One year after the operation, 1 patient developed mild anastomotic stoma stenosis without ischemia of the lower limbs, but no limb ischemia. Conclusion In patients with complex iliac anatomy unfavorable for bifurcated endografting, EVAR using AUI combined with CFBG is safe and effective.
