Objective To investigate the effect of Chlorogenic acid on oxidative and antioxidative system of kidney in diabetic rats.Methods 36 rats were randomly divided into three groups:normal group(N group),diabetes mellitus group(DM group)and diabetes group treated with chlorogenic acid(CA group).Ten weeks later,blood glu-cose,weight of body and kidney ,the activity of superoxide dismutase(SOD)and glutathione peroxidase(GSH-PX)lipidperoxidation(MDA),urinary albumin excretory rate(UARE)in renal tissue were measured.Results The levels of blood glucose were not significantly different between DM group and CA group,but the weight of rats and kid-ney and the activity of SOD and GSH-PX in CA group were higher than DM group,and MDA and UAER of CA group were lower(P<0.05 for each).Conclusion Chlorogenic acid effective in improving the antioxidativity,inhibiting oxidative stress and decreasing urinary albumin.

Objective:To evaluate the potential value of indocyanine green combined with methylene blue and methylene blue alone in the detection of sentinel lymph nodes (SLN) in breast cancer.Methods:The clinical data of 118 patients with early breast cancer from November 2016 to October 2018 in Dalian Central Hospital Affiliated to Dalian Medical University were retrospectively analyzed. Among them, 62 patients underwent SLN biopsy under methylene blue (methylene blue group, 160 SLN), and 56 patients underwent SLN biopsy under indocyanine green combined with methylene blue (combined group, 190 SLN). After SLN biopsy, patients underwent grade Ⅰ and Ⅱ axillary lymph node dissection.Results:There was no significant difference in the positive lymph node rate and accuracy rate between 2 groups ( P>0.05); the SLN dyeing rate and SLN biopsy positive rate in combined group were significantly higher than those in methylene blue group: 97.9% (186/190) vs. 93.1% (149/160) and 28.4% (54/190) vs. 18.1% (29/160), and there were statistical differences ( P<0.05); the false negative rate in combined group was lower than that in methylene blue group: 5.3% (3/57) vs. 14.7% (5/34), but there was no statistical difference ( P>0.05). Conclusions:In breast cancer patients, the dual -tracing method of indocyanine green combined with methylene blue is better than using methylene blue alone in identifying SLN and predicting the status of axillary lymph nodes, and it has a tendency to reduce the false negative rate.

Objectives To analyze the deployment of medical equipment and its impacts on medical services of hospitals.Methods Existing data collection,a survey of public hospitals and a chart review of acute myocardial infarction(AMI)inpatients were used to collect related data.Gini coefficients,Chi-square and multivariate model were used to analyze deployment of medical equipment and its impacts on medical services.Results The number of CTs and that of CTs per million population in Pudong new area were higher than those of MRIs and DSAs,and the distribution of CTs among districts in Shanghai was relatively equal(Gini coefficient was 0.20).But lack of DSAs in some public general hospitals had affected the AMI inpatient care.Conclusions Public hospitals and governments in China should keep at a balance the demand of medical services,deployment level of medical equipment,and financial affordability for the society,governments and hospitals.

Objective To observe the clinical curative effect of Depmas double blood purification system for acute severe organophosphorus pesticide poisoning.Methods Retrospectively study was carried out on 147 patients of acute severe organophosphorus pesticide poisoning.Patients were divided into four groups,the conventional treatment group treated with drug therapy,hemoperfusion group given HA230 hemoperfusion in addition to conventional treatment,plasma exchange combined with hemoperfusion group given HA230 hemoperfusion and plasma exchange therapy in addition to conventional treatment,and Depmas group treated with plasma separation by Baxter blood fiber and then given series HA230 and BS330 hemoperfusion treatment on the separated plasma in addition to conventional treatment.Survival rate,mean survival time of death patients,the concentration changes of cholinesterase and bilirubin in peripheral blood were observed.Results Compared to the conventional treatment group,survival rates of hemoperfusion group,hemoperfusion combined with plasma exchange group and Depmas group were higher,the mean survival time was longer,the cholinesterase concentration in peripheral blood was higher and the elevated bilirubin concentration was decreased with the differences statistically significant (P＜0.01).Compared to hemoperfusion group,the survival rates of hemoperfusion combined with plasma exchange group and Depmas group were higher,the mean survival time was longer,the cholinesterase concentration in peripheral blood were higher and the elevated bilirubin concentration was decreased with the differences statistically significant (P＜0.05).Besides,there were no significant differences between the survival rate,mean survival time,peripheral blood cholinesterase and bilirubin concentration of hemoperfusion combined with plasma exchange group and that of Depmas group (P＞0.05).Conclusions Depmas dual blood purification system has remarkable curative effect for the treatment of acute severe organophosphorus poisoning.

Objective To assess the effect of altitude hypoxia on the elderly patients with coronary artery disease (CAD). Methods Three subject groups were surveyed during their train trip on the highest railroad--the Qinghai-Tibet Railway: 22 elderly individuals with documented CAD, 20 healthy elderly controls, and 20 healthy young controls, all of whom from Beijing near the sea level (76 m). Survey questions addressed clinical features of their healthy conditions and aspects of their coronary disease. The baseline study was performed at Xining at an altitude of 2261 m, and then during acute exposure to altitudes of 2808 m, 4768m, 5072 m and 4257 m by train for 24 hours. Resting pulse rate, blood pressure, oxygen saturation, electrocardiograph (ECG), and cardiac work estimated by the heart rate-blood pressure double product were obtained five times in each subject at different altitudes. Results On arrival to altitudes between 4768 m and 5072 m, the older passengers, especially those with preexisting coronary disease, had higher HR, higher BP, and lower SaO2, as well as more frequent abnormalities on ECG, as compared to the younger healthy subjects. As compared with the healthy elderly controls, incomplete right bundle branch block, left ventricular hypertrophy, and ST segment depression were more frequently seen in the elderly coronary patients (P<0.01). Cardiac work in group 1 was increased by 13% 12 hours after arrival to altitudes between 2808 m and 5072 m. Oxygen saturation decreased significantly with the altitude increasing by train ascent but improved after inhalation of oxygen. Most of the older subjects tolerated their sojourn at high altitude well except one who developed angina repeatedly with a significant ST segment depression. Conclusions Coronary events and ECG signs of myocardial ischemia are rare in elderly individuals with CAD who travel from sea level to moderate altitudes of 1500m to 2800 m. Patients with CAD who are well compensated at sea level generally tolerate this moderate altitude well. However, it would be prudent for patients with CAD going to altitude above 3000 m. The patients should consult their physician before undertaking a trip to such altitude.

Objective To explore ultrastructure and cytoskeleton characteristics of bone marrow-deftved mesenchymal stem cells (MSCs) in patients with systemic lupus erythematosus (SLE).Methods MSCs were isolated from bone marrow of 2 SLE patients and 2 healthy controls.Their ultrastrnctures were examined by transmission electron microscope (TEM).The expression pattern of actin and vinculin was assessed by laser confocal microscopy (LCM).Results MSCs in patients with SLE presented with signs of ageing and lots of autophagosome could be found in most of the cells.F-actin was aggregated and condensed at the:border of cytoplasm.Vinculin was arranged disorderly and condensed in the cytoplasm.Conclusion The change of uhrastructure and cytoskeleton patterns of bone marrow derived mesenchymal cells of SLE patients may play an important role in the abnormal proliferation of these cells in vitro.
