Objective To observe the effects of CEJS combined with chemotherapy on the expression of VEGF in lewis lung carcinoma.Methods Tumor xenografts models were set up and randomly divided into five groups including control group,CTX CEJS,high-dose CEJS joint CTX(combination group 1),and middle-dose CEJS joint CTX(combination group 2).Paraffin imbedding and HE staining were performed,and the tissue Shape was observed by microscope after section.The expressions of VEGF in five groups were determined by immuno-histochemistry.Results The expression level of VEGF could be significantly down-regulated in CTX or combination group 1 and 2,compared with the control group(P＜0.05):CEJS group had no significant difference to the control group(P＞0.05);The average optical density in the combination group 1 and 2 showed no significantly difference to the CTX group(P＞0.05).Conclusion The inhibition of CEJS could not down regulate of the expression of VEGF,but CEJS could keep the affection of chemotherapy drugs on VEGF.

Objective To investigate the effects of Compound E-Jiao Slurry (CEJS) and Cyclophosphamide (CTX) on the inhibition of Lewis pulmonary carcinoma xenografts. Methods Tumor xenografts models were prepared and randomly divided into six groups by weight, including the control group,CTX, CEJS with the dosages of high, middle and low, with a total of ten mice in each group. The control mice were given normal saline 0.4ml by intragastric administration once daily, with a total of twelve times; The mice of CTX group were given CTX 0.2 ml by intraperitoneal injection every other day, with a total of six times; The mice of CEJS group were given CEJS 0.2 ml and saline 0.2 ml by intragastric administration; The mice of combination therapy group 1 were given CEJS 0.4 ml by intragastric administration once daily, and CTX 0.2 ml by intraperitoneal injection every other day; The mice of combination therapy group 2 were given CEJS 0.2 ml by intragastric administration once daily, and CTX 0.2 ml by intraperitoneal injection every other day; The mice of combination therapy group 3 were given CEJS 0.1 ml by intragastric administration once daily, and CTX 0.2 ml by intraperitoneal injection every other day. The weight of tumor xenografts were measured in the experiment,the inhibition rate of tumor xenografts were calculated according to the data after the dissection. Results The combination groups and CTX alone have an inhibition rate of over 50%, and the CEJS group 25.88%. In every experimental group, the weight of tumor showed statistical significance compared with the control (P<0.05). The value was(4.457±0.796)g, (2.105±0.651) g, (3.304±0.922) g, (1.668±0.267)g, (1.752±0.546)g and (2.075±1.061) g respectively according to the group sequence. There was no statistical significance of tumor weight in the groups of different dosages of CEJS plus CTX compared with the CTX group (P>0.05). Conclusion CEJS can't obviously enhance the sensitivity of tumor xenografts to CTX, but there is a trend for tumor inhibition.

Objective To study the impact of compound zhe-bei granule and adriamycin on p53 gene expression in the P388 xenograft tumor.Methods The tumor xenografts model was established by injecting the mouse lymphocytic leukemia cells(P388) in the subcutis of anterior axillary of Kunming mice,and then was treated with CZBG by intragastric administration and different doses of adriamycin by intraperitoneal injection(i.p.).After the end of the experiment,tumor was striped completely,and the expression of p53 gene in xenograft tumor of each group was detected by fluorescence quantitative polymerase chain reaction,and the relative quantification of p53 gene of each group was computed using 2-??Ct method.Results Comparing the 2-??Ct values of p53 gene relative expression of each group,no statistical significance was found(F=0.56,P=0.7557).And the relative expression value of p53 gene of CZBG joint high-dose ADM group was higher,while the relative expression value of CZBG joint low-dose ADM group was lower.Conclusion Combined use of CZBG and ADM is able to raise the expression of p53 tumor suppressor gene in the P388 xenograft tumor.

Objectives To explore the clinical symptoms, therapy and prognosis of tachycardia-induced cardiomyopathy (TIC) in children. Methods Clinical data of 22 children with TIC from July 2007 to July 2012 were retrospectively analyzed. Results TIC was mostly seen in male infants and 81.82%of TIC was caused by atrial arrhythmias. The clinical symptom relieved after arrhythmia and ventricular rates were under control with average effective treatment time of (14.00 ± 8.20) days. Ten patients had tachycardia recurrence, 7 of them had atrial arrhythmia and their clinical symptoms were improved after treatment;while 3 of them showed longer time of therapy with average treatment time of (19.50±8.40) days (P<0.05). Five children underwent radiofrequency ablation before school age and got good therapeutic effect. The post-treatment echocardiographic parameters showed cardiac function of TIC children was significantly improved after treatment, including left ventricular end-diastolic diameter index, left ventricular end-systolic diameter index, left ventricular ejection fraction and shortening score (all P<0.05). Conclusions Childhood TIC is a reversible myocardial dysfunction and its prognosis is good. TIC can be induced by various types of tachyarrhythmias and normally by atrial arrhythmia. The preferred treatment of TIC is administration of antiarrhythmic drugs but radiofrequency ablation is needed to ventricular arrhythmias induced TIC.

Background The pathogenesis of diabetic retinopathy (DR) might be related with oxidative stress and its mechanism has not been fully elucidated.Grape seed proanthocyanidin extracts (GSPE),a powerful antioxidant,plays roles in some systemic diseases.However,the effect and mechanism of GSPE in DR has not been illuminated clearly.Objective This study was to investigate whether GSPE has a protective effect on the retinas of diabetic subjects and explore its mechanism.Methods Thirty SPF adult Wistar rats were divided into the control group,diabetic group and diabetes + GSPE group according to the randomized number table.Diabetic models were induced by intraperitoneal injection of 100 mg/kg strebtozotocin (STZ) prepared with citrate buffer,and only the equal amount of citrate buffer was used in the same way in the control group.GSPE solution was intragastrally used 250 mg/kg daily in the rats of the diabetes+GSPE group from injective day through 8 weeks,and distilled water was used in the same way in the rats of the control and diabetic groups.The rats were sacrificed in the eighth week after injection and the retinas were isolated.The morphology of the retina were examined by hematoxylin and eosin stain.Retinal homogenatewas prepared for the assay of superoxide dismutase (SOD),glutathione peroxidase (GSH-Px) activity and malonaldehyde (MDA) content.The expressions and location of nuclear erythroid related factor 2 (Nrf2) was determined by immunochemistry,and the expressions of Nrf2 and heme oxygenase-1 (HO-1) were quantitatively analyzed by Western blot.The apoptosis of retinal cells was detected by TUNEL.Results In the eighth week after modeling,the blood glucose levels were significantly higher and the body weight was lower in the rats of the diabetic group and diabetes+GSPE group compared with the control group (all at P＜0.01).Retinal structure was normal in the rats of the control group.However,loose tissue,irregular arrangement of cells and thickness decrease of retinal fiber layer,retinal ganglion cell layer and inner plexiform layer were exhibited in the rats of the diabetic group,while the morphology abnormality was slight in the rats of the diabetes+GSPE group.The SOD and GSH-Px activities and MDA content were significantly different among the 3 groups (F =11.010,P =0.001 ; F =12.072,P =0.000 ; F =25.224,P=0.000),and activities of SOD and GSH-Px in the retinas were significantly lower,and the MDA level was higher in the rats of diabetic group than those of the diabetes+GSPE group and the control group (all at P＜0.01).The relative expressing levels of Nrf2 were (165.5±29.4) ％ and (134.8 ±7.8) ％ in the diabetes+ GSPE group and diabetic group,with a significant difference between them (t=2.450,P=0.044).Compared with the diabetic group,the expressing level of the HO-1 was sigficantly increased ([170.2±22.0)％ versus [125.3±9.2] ％,t =2.360,P =0.002).TUNEL showed that the retinal apoptotic cells of diabetic rats were mainly located in the retinal fiber layer,RGCs layer,inner and outer nuclear layer,and the number of apoptotic cells was less in the diabetes+GSPE group compared with the diabetic group under the fluorescence microscope.Conclusions GSPE can play a protective role on diabetic rats by activating Nrf2 pathway and therefore improving retinal oxidative stress and decreasing apoptosis.

Objective To evaluate the effect of exogeneous adiponectin on hippocampal advanced glycation end products (AGEs)-reactive oxygen species (ROS)-endoplasmic reticulum stress (ERS) pathway in aged mice with postoperative cognitive dysfunction (POCD).Methods Thirty-two healthy male C57BL/6 mice, aged 18 months, weighing 20-25 g, were randomly divided into 4 groups (n=8 each) using a random number table: control group (group C), POCD group, exogeneous adiponectin group (group APN), and vehicle group (group Veh).Splenectomy was performed to establish the POCD model in aged mice anesthetized with intraperitoneal pentobarbital sodium.In group APN, adiponectin 0.1 μg/g (in 2 μl of phosphate buffer solution) was injected into the lateral cerebral ventricle at 30 min before establishing the model.Phosphate buffer solution 2 μl was given at 30 min before establishing the model in group Veh.Cognitive function was assessed on day 7 after surgery.The mice were then sacrificed, and the hippocampus was harvested for determination of the area of AGE deposition (by immunohistochemistry), levels of ROS (by flow cytometry), and levels of glucose-regulated protein 78 (GRP78), C/EBP-homologous protein (CHOP), caspase-12 and ROS (using Western blot).Results Compared with group S, the freezing time in the contextual fear conditioning test was significantly shortened, the area of AGE deposition and levels of ROS, CHOP and caspase-12 were increased, and the level of GRP78 was decreased in POCD, APN and Veh groups.Compared with POCD and Veh groups, the freezing time in the contextual fear conditioning test was significantly prolonged, the area of AGE deposition and levels of ROS, CHOP and caspase-12 were decreased, and the level of GRP78 was increased in group APN.Conclusion Exogeneous adiponectin decreases the occurrence of POCD probably by blocking hippocampal AGEs-ROS-ERS pathway in aged mice.
