Objective To investigate the protective effects of left ventricular myocardial perfusion after delivery of acidic fibroblast growth factor (aFGF) in rats with diabetic cardiomyopathy (DCM) by using ultrasound‐targeted microbubble destruction ( UTMD ) with real‐time myocardial contrast echocardiography( RT‐MCE) . Methods Among 64 male SD rats ,52 rats were randomly selected and were induced DCM by streptozotocin through intraperitoneal injecting ,the other rats as normal control group . DCM rats were randomly divided into the DCM model group ,aFGF only group ,SonoVue‐aFGF group and the SonoVue‐aFGF+ UTMD group in this study . The aFGF only group rats were injected with aFGF solution through tail vein ,the SonoVue‐aFGF group were injected with SonoVue‐aFGF solution through tail vein and SonoVue‐aFGF+ UTMD group rats were injected with SonoVue‐aFGF solution through tail vein and using UTMD simultaneously . All rats underwent conventional echocardiography and RT‐MCE exams before and 4 weeks after intervention . Left ventricular ejection fraction ( LVEF) and left ventricular fraction shortening( LVFS ) were measured by conventional echocardiography . The plateau intensity ( A ) ,initial slope of the curve (β) and myocardial blood flow ( A ×β) of left ventricular anterior wall at the papillary muscle level were measured in left ventricular short‐axis view by RT‐MCE . Results Before intervention , LVEF and LVFS in the DCM model group ,aFGF only group ,SonoVue‐aFGF group and the SonoVue‐aFGF+UTMD group were significantly lower than in the normal control group ( P <0 .01) .During 4 weeks after intervention ,LVEF and LVFS in the aFGF only group ,SonoVue‐aFGF group and the SonoVue‐aFGF+UTMD group were slightly increased than those in the DCM model group ,but no statistically significant differences were found ( P > 0 .05) ,however A and A × β in the SonoVue‐aFGF+ UTMD group were significantly increased than those in the DCM model group( P < 0 .01) . Compared with the same group before intervention ,A and A ×βin the SonoVue‐aFGF+UTMD group were higher ( P <0 .05) and these in the DCM model group were lower during four weeks after intervention ( P < 0 .05) . Conclusions Acidic fibroblast growth factor delivered by using UTMD can improve the left ventricular myocardial perfusion in diabetic cardiomyopathy rats .

[ ABSTRACT] AIM:To explore the mechanisms of fluctuant high blood glucose-induced apoptosis of hepatocytes. METHODS:SD rats were randomly divided into normal control group ( N) , stable high blood glucose group ( S) , fluctu-ant high blood glucose group ( F) and insulin group ( I) .Diabetic rats were induced by intraperitoneal injection of strepto-zotocin (65 mg/kg) , and the fluctuant high blood glucose animal model was induced by intraperitoneal injection of ordinary insulin and glucose at different time points every day.The blood glucose fluctuation patterns of the animals in F group with-in 12 weeks were similar every day and no significant difference of the HbA1c concentration was observed compared with S group, indicating that the fluctuant hyperglycemia was successfully established in F group.The activity of superoxide dis-mutase ( SOD) and glutathione peroxidase ( GSH-Px) , and the content of malondialdehyde ( MDA) and nitric oxide ( NO) in the homogenate of the liver tissues were detected by colorimetry.The mRNA and protein levels of JNK, p-JNK, Bax and Bcl-2 were examined by RT-PCR and Western blot.RESULTS:After 12 weeks, the increases in the intakes of food and water, the urine output, and the abnormal liver function were observed in S group, I group and F group.Compared with N group, the MDA level was increased, the content of NO and the activity of SOD and GSH-Px were decreased, and up-regu-lation of JNK mRNA and p-JNK and Bax proteins, and down-regulation of Bcl-2 were also found in S group, I group and F group.The above effects were more obviously showed in F group.CONCLUSION:Oxidative stress activates JNK-MAPK signaling pathway, which is involved in fluctuant high glucose-induced apoptosis of hepatocytes.

To investigate the anti-vasculature effects and the anti-glioma effects of attenuated Salmonella typhimurium vaccine strain expressing VEGFR2 (flk-1) gene, plasmid pcDNA3.1-flk1 was constructed and electro-transfected into live attenuated Salmonella typhimurium strain SL7207. Mouse models of intracranial G1261 glioblastoma were treated with an orally administered attenuated Salmonella typhimurium expressing flk-1 gene. The survival period was recorded and vessel density was observed by immunofluorescence. CTLs activity was measured by MTT assay. Our results showed that attenuated Salmonella typhimurium vaccine strain expressing flk-1 gene could significantly inhibit glioblastoma growth, reduce vessel density, prolong the survival period and improve the survival rate in these mice. The flk-1 specific CTLs activity was increased obviously after the vaccination. Our study showed that attenuated Salmonella typhimurium vaccine strain expressing flk-1 gene could break peripheral immune tolerance a in glioma gainst this self-antigen and kill endothelial cells by the orally administered vaccine and can be used for both prophylactic and therapeutic purposes.

Inflammatory bowel disease(IBD)is a non-specific and easily recurrent chronic inflammatory disease of the intestine,mainly including ulcerative colitis(UC)and Crohn's disease(CD).Its etiology and pathogenesis have not been fully elucidated,but it is currently believed to be related to environmental,genetic,immune response abnormalities,and other factors.At present,IBD has become a disease of great concern worldwide.According to the epidemiological data and data of inflammatory bowel disease in China,the incidence rate of IBD is on the rise year by year in China,but so far,there has not been a drug that can completely cure the disease.Recently,glucagon-like peptide(GLP)and its degradation enzyme inhibitor dipeptidyl peptidase-4(DPP-4)inhibitors have attracted widespread research and attention in the treatment of IBD.This article reviewed the roles and mechanisms of GLP and DPP-4 inhibitors in the treatment of IBD diseases.

Objective To investigate the clinical effects of therapeutic hypothermia on the mortality and neurological function recovery in patients with acute large hemispheric infarction (LHI).Methods Seventy-three acute LHI patients (within 24 hours of symptom onset) admitted to our hospital from February 2015 to July 2016 were randomized to the hypothermia group (37 patients)and the control group (36 patients).Patients in the hypothermia group were given standard medical treatment and the surface cooling with a target temperature between 32-35 ℃ lasting for 5-7 days.Patients in the control group were given standard medical treatment and maintained a target temperature of normothermia.All patients were observed the primary end points including mortality and the modified Rankin Scale (mRS) score at 3 months.Results At three months,nine patients of survivors in the hypothermia group had good outcome (mRS score 0-3),whereas only five patients of survivors in the control group,though there was no significant difference (9/17 vs 5/19,x2 =2.676,P＞ 0.05)between the two groups.Twenty patients (54.1％)died in the hypothermia group,while 17 patients(47.2％) in the control group(x2 =0.341,P ＞0.05).Conclusion Therapeutic hypothermia is safe and feasible to patients with acute LHI,but may neither reduce mortality nor improve the neurological outcome in survivors.

Objective:To evaluate the clinical efficacy of multi-disciplinary single center's CCCG-HB-2016 regimen in the treatment of hepatoblastoma (HB) in children.Methods:Clinical data of 36 HB patients treated with CCCG-HB-2016 program from Aug 2016 to March 2020 were analyzed.Results:These 36 patients included 20 boys and 16 girls. The serum AFP was all higher than 2 792 ng/ml,there was a correlation between AFP and tumor risk stratification ( H=14.973, P<0.05). Twenty eight cases (77.78%) were epithelial type and 8 cases (22.22%) were mixed epithelial mesenchymal type.All children were treated by tumor resection combined with chemotherapy, and there was a correlation between tumor risk stratification and surgical resection of liver lobe ( H=8.847, P<0.05). The probability of bone marrow suppression in the low-risk group was 58.33% (35/60),that in the intermediate-risk group was 73.49% (61/83) and in the high-risk group was 80.23% (69/86).All 36 cases were followed up to March 31, 2020,with an average follow-up of 21.9 months and the median survival was 22.5 months.The overall survival rate (OS) and event-free survival rate (EFS) were 97.2% and 83.3% respectively. Conclusions:The multidisciplinary CCCG-HB-2016 regimen was with a high success rate and along with a high incidence of bone marrow suppression.

Objective:To investigate the characteristics of cognitive impairment caused by solitary cerebellar infarction.Methods:From January 2017 to January 2019, 76 inpatients with acute cerebellar infarction treated at our hospital were continuously enrolled as the infarction group and 88 outpatients without cerebral infarction at our hospital during the same period were collected as the control group.The patients in the two groups were evaluated by the Montreal Cognitive Assessment Scales(MoCA)and Mini-Mental State Examination(MMSE)Scale at 14 days, 1 month and 3 months after the onset of solitary cerebellar infarction, respectively.Results:The MoCA and MMSE scores were lower in the infarction group than in the control group at 14 days, 1 month and 3 months after the onset of solitary cerebellar infarction(MoCA: 23.9±6.13 vs.28.1±2.51, 22.6±6.07 vs. 28.2±2.28 and 22.5±6.19 vs. 28.2±2.15, t=5.88, 8.03 and 8.09, P<0.001; MMES: 25.7±4.54 vs.28.3±2.25, 24.9±4.63 vs.28.2±2.14 and 24.6±4.43 vs.28.3±2.16, t=4.74, 5.99 and 6.94, all P<0.001). Cognitive function scores showed that three major recognition domains of visual space and executive function, attention and memory had statistically significant difference between the two groups( P<0.05), and the differences in three recognition domain of naming, calculating force, directional force between the two groups were not statistically significant( P<0.05). Conclusions:There is a clear correlation between cerebellar infarction and cognitive impairment, which is mainly manifested in three aspects of visual space and executive function, attention and memory.The great attention should be paid to screening and intervention on the three aspects in clinical work, which is of great significance for improving the quality of life and prognosis of patients.

The aim of this study was to evaluate the roles of interleukin (IL)-17A in risk stratification and prognosis of patients with sepsis-associated acute kidney injury (SAKI). Methods: We enrolled 146 sepsis patients (84 non-SAKI and 62 SAKI patients) admitted to the emergency department from November 2020 to November 2021. Patients with SAKI were differentiated based on the severity of acute kidney injury. All clinical parameters were evaluated upon admission before administering antibiotic treatment. Inflammatory cytokines were assessed using flow cytometry and the Pylon 3D automated immunoassay system (ET Healthcare). In addition, a receiver operating characteristic (ROC) curve was utilized to determine the prognostic values of IL-17A in SAKI. Results: The levels of creatinine, IL-2, IL-4, IL-6, IL-17A, tumor necrosis factor alpha, C-reactive protein, and procalcitonin (PCT) were significantly higher in the SAKI group than in the non-SAKI group (p < 0.05). The level of IL-17A revealed significant differences among stages 1, 2, and 3 in SAKI patients (p < 0.05). The mean levels of PCT, IL-4, and IL-17A were significantly higher in the non-survival group than in the survival group in SAKI patients (p < 0.05). In addition, the area under the ROC curve of IL-17A was 0.811. Moreover, the IL-17A cutoff for differentiating survivors from non-survivors was 4.7 pg/mL, of which the sensitivity and specificity were 77.4% and 71.0%, respectively. Conclusion: Elevated levels of IL-17A could predict that SAKI patients are significantly prone to worsening kidney injury with higher mortality. The usefulness of IL-17A in treating SAKI requires further research.
