Objective To investigate the effects and possible mechanism of Fructus lycii on renal calcium oxalate stone formation in rats. Methods Wistar rats were divided into several groups according to different stone inducer (cigarette smoking, ethylene glycol solution drinking or combination of both), either Fructus lycii infusion interference or not and different interfering concentrations (10% and 25%). Besides, a blank control group was set. After treatment for 40 d, 24 h urine was collected, and renal tissue samples were obtained. The concentrations of calcium, oxalate and citric acid in urine were measured. The deposit condition of calcium oxalate crystals in nephric tubules was observed and scored. The levels of malondialdehyde (MDA) and activity of total-superoxide dismutase (T-SOD) in renal tissues were detected. Apoptosis cells in kidney were observed with TUNEL staining, and index of apoptosis was calculated. Results Compared with blank control group, the urine calcium concentration in group of combination of cigarette smoking and ethylene glycol solution drinking were significantly higher (P<0.01), the scores of calcium oxalate crystals in renal tubules, the levels of MDA in renal tissues and the index of apoptosis of renal tubule epithelial cells in groups of ethylene glycol solution drinking and combination with smoking were higher, while the concentrations of citric acid in urine and activity of T-SOD in renal tissues were lower. Ten percent and 25% Fructus lycii infusion significantly decreased the urine concentrations of calcium in group of combination of cigarette smoking and ethylene glycol solution drinking (P<0.01), decreased the scores of calcium oxalate crystals in renal tubules, the levels of MDA in renal tissues and the index of apoptosis of renal tubule epithelial cells in groups of ethylene glycol solution drinking and combination with smoking, and increased the concentrations of citric acid in urine and activity of T-SOD in renal tissues. There was no significant dose-effect relationship between two concentrations of Fructus lycii infusion. Conclusion Fructus lycii infusion can effectively inhibit the formation of renal calcium oxalate stone in rats with smoking and/or ethylene glycol drinking by reducing the free radicals and apoptosis of renal tissue, decreasing the concentration of elements for stone formation and increasing the concentration of elements for inhibition of stone formation in urine.

Objective To detect the expression of E-cadherin and ?-catenin in breast carcinoma and analyze the relationship between E-cadherin and ?-catenin and the clinicopathological features. Methods The expression of E-cadherin and ?-catenin in breast cancer, paracarcinoma breast tissue, simple mastoplasia and atypical mastoplasia were detected by immunohistochemical method and the results were compared. Results The abnormal expression rates of E-cadherin and ?-catenin in breast cancer tissue were 51.9% and 61.1 %,respectively. Abnormal expression of E-cadherin was significantly correlated with histological grade. Abnormal expression of ?-catenin was significantly correlated with TNM staging, axillary lymph nodes metastasis and postoperative distant metastasis. COX multiple factor analysis showed that neither E-cadherin nor ?-catenin expression was an independent indicator for the prognosis of breast cancer. Conclusions Abnormal expressions of E-cadherin and ?-catenin are correlated with occurrence and development of breast carcinoma. Abnormal expressions of E-cadherin and ?-catenin are good indicators to judge invasion and metastasis of breast carcinoma.

Objective To study the technical skill and therapeutic effect of aortic isolation for treating DeBakey Ⅲ dissecting aneurysm.Methods Among 20 cases of DeBakey Ⅲ dissecting aneurysm,7 cases were with DeBakey Ⅲ a and 13 cases were with DeBakey Ⅲb.Imaging examinatin showed that among the 20 cases there were 5 cases with more than two tearings at difreret site.Covered stent was used to close left subclavian artery in 7 cases and distaI aortic isolation of left subclavian artery was conducted in other 13 cases.Restuls All cases were followed up for 3-40 months,finding that 19 cases survived but one case died because of pseudocoele bronchial fistula hemoptysis 18 months later.Conclusions Endovasular covered stent grafts is the simple,safe and effective way to treat dissecting aneurysm.

ObjectiveTo investigate the efficiency of autologous transplantation of peripheral blood stem cells for treatment of patients with diabetic lower limb ischemia.MethodsEighteen patients of type 2 diabetes with diabetic lower limb ischemia (30 legs) were treated by autologous transplantation of peripheral blood stem cells.ResultsThe limb pain, cool feeling and numbness feeling improved significantly after PBSC transplantation,the improvement rate were 96.7％, 100.0％ and 95.8％ respectively.Intermittent claudication was also relieved significantly, total remission rate was 76.9％.The ABI and TcPO2 of patients increased significantly at 3 months after transplantation.After the transplantation ABI raised from 0.60 ± 0.11 to 0.71 ±0.12(t =-6.882, P ＜ 0.01) .93.3％ of patients' TcPO2 raised in different degrees.The foot infections were well controlled.Ulcer or toes gangrene got better or healed.No obvious complications or adverse reaction were observed after the transplantation.ConclusionAutologous transplantation of peripheral blood stem cells shows to be a simple, safe and effective method in treating patients with diabetic lower limb ischemia.

Objective To analyze the clinical characteristics of suspected acute aortic dissection with ST-segment elevation detected by inferior leads in order to avoid the misdiagnosis of acute aortic dissection facilitating an appropriate treatment strategy carried out in time.Methods A total of 14 patients with suspected acute aortic dissection with ST-segment elevation detected by inferior leads were enrolled.Their clinical presentation,ECG features,imaging findings,laboratory testing,coronary angiography results, treatment and outcome were retrospectively analyzed.Results Clinical characteristics of suspected acute aortic dissection with ST-segment elevation detected by inferior leads suggested that hypertension as a single risk factor accounted for 79%.The patients with normal blood pressure or high blood pressure in emergency visits accounted for 86%.The amplitude of ST elevation in lead Ⅲ was greater than that in lead Ⅱ,and lead Ⅲ accompanied with ST elevation in lead V1 or V4R accounted for 86%.Significantly elevated D-dimer >2 000 ng/mL was found in those patients.Coronary angiography showed that the opening of coronary artery not seen,normal coronary arteries or a simple right coronary artery proximal lesion.Transesophageal echocardiography and computed tomography angiography were used to identify the diagnosis with 100%accuracy.The mortality rate of this group was 50%.Conclusions Patients with acute aortic dissection evidenced by ST-segment elevation detected by inferior leads are in critical setting of high mortality. Emergency surgical treatment can significantly improve the survival rate of patients.

Objective To investigate the value of three-dimensional speckle tracking imaging (3D-STI) in quantitative evaluation of left ventricular global strain in patients with atrial septal defect (ASD) before and after transcatheter closure.Methods Totally 35 patients with secondary ASD who received successful transcatheter occlusion were selected.Routine echocardiography and 3D-STI examination were performed before the operation,2 days,1 month,3 months and 6 months after the operation.Routine echocardiography was used to obtain the parameters of left ventricular end diastolic diameter (LVEDD),left ventricular end systolic diameter (LVEDS),left ventricular end diastolic volume (LVEDV),left ventricular end systolic volume (LVESV),stroke volume (SV) and other parameters.The left ventricular global peak longitudinal strain (GPLS),left ventricular global peak circumferential strain (GPCS),left ventricular global peak radial strain (GPRS) and left ventricular global peak area strain (GPAS) were examined with 3D-STI.The preoperative and postoperative parameters at each time point were analyzed statistically.Results Routine echocardiography showed that LVEDD,LVEDS,LVEDV,LVESV and SV increased significantly after operation,but no significant difference was found to compare each other 2 days,1 month,3 months and 6 months after operation (all P＞0.05).3D-STI examination showed that left ventricular GPLS,GPCS,GPRS and GPAS increased after operation,and the most increase was noticed at the second day after transcatheter occlusion.GPLS,GPCS and GPAS 6 months after operation were larger than those 3 months after operation (all P＞0.05).Conclusion 3D-STI technique can evaluate the left ventricular global strain in patients with ASD before and after occlusion.Compared with conventional echocardiography,3D-STI technique can objectively and effectively evaluate the changes of left ventricular systolic function.

Objective:To analyze the effective and safety of endovascular aneurysm repair (EVAR) for ruptured abdominal aortic aneurysm (RAAA) at one tertiary center, and to improve the outcomes of RAAA under fast-track protocol.Methods:Nineteen cases of RAAA in the 940th Hospital of Joint Logistic Support Force of PLA from January 2014 to December 2020 were reviewed retrospectively. EVAR-fist strategy was employed from the emergency room to the operating room by using fast-track protocol. Preoperative management, anatomic characteristics, choice of anesthesia, operative procedures and postoperative complications were collected and analyzed. Abdominal compartment syndrome (ACS) and hospital mortality were paid special attention.Results:Nineteen cases were undergone EVAR procedures. The age was (73.4 ± 7.4) years old, and the AAA size was (67.8 ± 13.6) mm. Two cases underwent cardiopulmonary resuscitation at emergency department. General anesthesia was used in 13 patients and local anaesthesia in 6 patients. Successful stent graft deployment was achieved in all cases. The duration from emergency room to operating room was (84.8 ± 22.4) min. The hospital stay time was (9.7 ± 5.7) d. The hospital mortality was 5/19. The 5 deaths were reviewed: 3 died for multiple organ failure, 1 for irreversible shock, and 1 for ongoing bleeding.Conclusions:Excellent results were confirmed by using EVAR-first strategy for RAAA. The management of hemodynamically unstable state, standardized endovascular procedure, fast-track program and multidiscipline team collaboration were the very important determining factors for the implementation of EVAR. Focused efforts to reduce RAAA mortality are warranted.
