RESUMO
Objective:To explore the application value of dual contrast-enhanced ultrasound in the differential diagnosis of renal cystic lesions.Methods:Eighty-four cases with renal cysts who were diagnosed by routine ultrasound in Zhejiang Cancer Hospital and Zhejiang Xiaoshan Hospital from January 2019 to October 2020 were included in the study. Intravenous contrast-enhanced ultrasound and enhanced MRI were performed to differentiate benign and malignant cysts. Patients with benign cysts underuent intravenous pyelography and intracapsular contrast-enhanced ultrasound. Before sclerotheraphy to exclude renal pelvic cysts. The diagnostic results of dual radiography were compared with MRI and intravenous pyelography.Results:Among 84 patients with suspected renal cysts, the diagnostic accuracy of enhanced MRI for cystic renal cancer was 97.62%, and the sensitivity was 97.62%. The diagnostic accuracy of intravenous contrast-enhanced ultrasound was 98.81, the sensitivity was 100%, and the specificity was 98.73%. There was no statistically significant difference between the two groups (all P>0.05). 77 cases were diagnosed as benign renal cysts, the detection rate of intravenous pyelography was 9.1% (7/77), the detection rate of renal pelvic cysts by intracystic ultrasonography was 6.5% (5/77). With intravenous pyelography as the gold standard, the diagnostic accuracy of intracapsular contrast-enhanced ultrasound was 97.4% (75/77), the sensitivity was 71.4% (5/7), and the specificity was 100% (70/70). Conclusions:Compared with enhanced magnetic resonance and intravenous pyelography before renal cyst sclerosing therapy, there is no difference in diagnostic efficiency of double contrast ultrasound for benign and malignant cysts. The diagnostic efficiency of renal pelvic cysts is high, and the operation is convenient. It can identify cystic renal cancer and cysts from the renal pelvis and improve the safety of sclerotherapy.

RESUMO
Objective@#To investigate the effect of triptolide, a specific inhibitor of heat shock protein 70 (HSP70), on apatinib resistance in gastric cancer cells line MKN45.@*Methods@#The apatinib-resistant cells (MKN45/AR) and MKN45 parental cells were treated with apatinib, triptolide and apatinib combined with triptolide, respectively. CCK-8 assay was performed to determine the half maximal inhibitory concentration (IC50) of MKN45/AR and MKN45 cells in the presence of different treatment. The mRNA expression of heat shock protein gene (HSPA1A and HSPA1B) was detected by RT-PCR, while the protein expression of heat shock protein 70 was analyzed using Western blot in MKN45/AR and MKN45 cells.@*Results@#The IC50 values of apatinib-sensitive and apatinib-resistant MKN45 cells were 10.411 μmol/L and 70.527 μmol/L, respectively, showing a significant difference (P<0.05). The mRNA expression of HSPA1A and HSPA1B in MKN45/AR cells was significantly higher than that in MKN45 cells (P<0.001). The protein expression of heat shock protein 70 was significantly decreased after 0.25 μmol/L triptolide treatment in MKN45/AR cells (P<0.01). When heat shock protein 70 was inhibited by triptolide, the IC50 value of apatinib in MKN45/AR cells was reduced to 11.679 μmol/L, which was significantly lower than cells treated with apatinib alone (P<0.05).@*Conclusions@#The apatinib-resistant MKN45 cells have high levels of heat shock protein 70. Low doses of triptolide can significantly inhibit heat shock protein 70, leading to reverse the resistance phenotype of MKN45/AR cells. Therefore, inhibition of heat shock protein 70 provides a new therapy strategy for patients with apatinib resistance.

Organ coefficient of spleen was significantly increased in Slit2-Tg mice, but the tissue structure appeared normal. There were significant changes in the counts of erythrocytes, platelets, eosinophils, and biochemistry of glucose, globulin, urea nitrogen, triglycerides, HDL, and atherosclerosis index. Echocardiography showed no significant differences in the morphology and function of the Slit2-Tg hearts except in the left ventricular anterior wall thickness at the end-diastolic state. Compared with the C57BL/6 J mice, 535 genes out of 17513 genes in the Slit2-Tg hearts were increased or decreased, mainly involving 15 biological process or signal transduction pathways. Conclusions This study has collected the biological parameters of Slit2-Tg mice and suggests that this model animal is suitable for the studies of cardiovascular diseases.
RESUMO
<p><b>OBJECTIVES</b>To study the correlation between MRI apparent diffusion coefficient (ADC) and expression of Ki-67 in gastric cancers, and to investigate the application of ADC value in diagnosing the malignance of gastric cancer.</p><p><b>METHODS</b>A retrospective cohort analysis was performed on 87 gastric cancer patients who received MRI examination and radical resection at Zhejiang Provincial Hospital of Traditional Chinese Medicine from November 2014 to August 2015. All the postoperative resected samples were confirmed as gastric cancer. Preoperative MRI examination was performed by using Siemens 3.0-T Verio MRI with following parameters: section thickness 3 mm, gap 1 mm, matrix 182×320, field of view 40 cm. Plain scan was followed by T1-weighted fat suppression technique VIBE 3D(TR3.92/TE1.39,90degree) scans at arterial phase (the 30th second), portal venous phase (the 60th second), lag period (the 90th second), axial planes and coronal planes (the 180th second), and sagittal planes (the 210th second), respectively. ADC value of tumor was measured at b-factor of 800 s/mmand ADC map was generated from DWI data on the work station. The expression of Ki-67 in cancer tissue was detected by routine immunohistochemical (SP) staining after surgery. Correlation between ADC value and the expression of Ki-67 in gastric cancer was analyzed.</p><p><b>RESULTS</b>Irregular thickening of the gastric wall and inhomogeneous enhancement of the tumor after injection of the contrast material appeared in gastric cancer. Gastric cancer tissue presented hyperintensity and normal gastric wall presented isointensity in DWI image (b=800 s/mm). Compared with normal gastric tissue, mean ADC value of gastric cancer tissue was significant lower [(1.114±0.265)×10mm/s vs. (2.032±0.202)×10mm/s, t=26.209, P=0.000]. The ADC values of high-middle differentiation group, middle-low differentiation group, low differentiation group and signet ring cell carcinoma/mucinous adenocarcinoma group were (1.347±0.234)×10mm/s, (1.179±0.257)×10mm/s, (0.996±0.185)×10mm/s and (1.082±0.230)×10mm/s, respectively. The difference of mean ADC value among different tumor stages was significant(F=8.498, P=0.000). Along with the Ki-67 expression up-regulated, the ADC value decreased in cancer tissue. The Ki-67 expressions in cancer tissue was negatively correlated with cancer ADC values (r=-0.570, P=0.000). Furthermore, negative correlations of Ki-67 expressions with ADC values of high-middle differentiation group (r=-0.627, P=0.016), low differentiation group (r=-0.787, P=0.000) and signet ring cell carcinoma/mucinous adenocarcinoma group (r=-0.792, P=0.000) were observed respectively, while Ki-67 expression was not correlated with ADC value of middle-low differentiation group.</p><p><b>CONCLUSION</b>The ADC value of gastric cancer can reflect the level of tumor differentiation, and is negatively correlated with Ki-67 expression in cancer tissues.</p>
RESUMO
Objective To provide a basis for clinical diagnosis,a serum metabonomic dynamic study was carried out on the Tg2576 mouse model at different stages of Alzheimer's disease(AD) whose pathological progress is similar to that of human AD patients.Methods Serum samples of Tg2576 mice were collected at the early(6 months) and late(12 months) stages of Alzheimer's disease.The 1H NMR spectra of the serum samples were collected and the metabolic characteristics were analyzed by multivariate analysis.Results Significant differences in serum metabonomics were found in the transgenic Tg2576 mice and C57 mice at 6 and 12 months of age,and there were significant metabolic changes in Tg2576 mice at different stages of Alzheimer's disease.Compared with C57 mice,the Tg2576 mice at early stage of Alzheimer's disease showed higher levels of serum lactate,myo-inositol and amino acids(such as leucine,isoleucine,alanine),and lower levels of lipids,choline,phosphorylcholine,glycerol phosphorglcholine,betaine,glycine and glucose.At the late stage of Alzheimer's disease,the transgenic Tg2576 mice had higher levels of lactate,myo-inositol and alanine,while the serum levels of lipids,choline,phosphorylcholine,glycerophosphorylcholine,betaine,and glycine continued to drop.Meanwhile glutamine and creatine levels started to decline.By comparing the early and late serum metabolites of Alzheimer's disease,serum metabonomic profiles of the late stage of Alzheimer's disease indicated an up-regulation of lactate,myo-inositol and alanine,and a down-regulation of lipids,choline,phosphorylcholine and glycerophosphorylcholinelevels.Moreover,the levels of lactate,lipids,choline,phosphorylcholine and glycerophosphorylcholine showed statistical significance at the early stage of AD,and they were closely correlated with the severity of Alzheimer's disease.Conclusions The above results show that the changes of lactate,myo-inositol and alanine are positively-correlated with the development of AD,while the serum levels of lipids,choline,phosphorylcholine and glycerophosphorylcholine are inversely-proportional to the severity of AD.These metabolites are dynamically and progressively changed along with the disease progression,which hopefully may serve as early metabolic markers for the diagnosis of AD in clinical practice.

Objective To study the effect of heterozygous deficiency of SGT gene on the hematological and biochemical parameters of mice in young and elderly ages.Methods Blood samples were analyzed for complete hematological and biochemical parameters from heterozygous SGT-deficient and wild-type mice of 10-weeks and 6-months old mice, respectively.Results Age-related changes in most indexes were found statistically significantly different between young and elderly mice with the same genotype.Compared with the wild type at the same age, the platelet large cell ratio (P-LCR) was lower in young heterozygous SGT-deficient mice.However, platelet count, plateletcrit (PCT) and neutrophil count were more significantly lower in elderly heterozygous SGT-deficient mice (P<0.05).There was no significant difference for biochemical parameters ALT, AST, LDH, urea nitrogen, creatinine and blood glucose.Total and unconjugated bilirubin as well as ALP were significantly higher in elderly heterozygous SGT-deficient mice but not for conjugated bilirubin (P<0.05).In addition, significant differences existed for the lipids between two elderly groups (P<0.05).Conclusions Heterozygous deficiency of SGT gene induced changes of some hematological and biochemical parameters in elderly mice.It provides helpful information for further investigation on SGT involvement in some biological and pathological processes.
RESUMO
Objective To establish a mouse model of diethylnitrosamine(DEN)-induced hepatocellular carcinoma (HCC),and to explore the effects of two different diet formulas on the establishment of DEN-induced HCC model.Methods SPF C57BL/6 mice (8 males and 8 females) were injected intraperitoneally with 25 mg/kg DEN at day 14 to establish a HCC model.The mice were divided into two groups after weaning.One group was fed with the SPF class rodents cereal-based diet,another group was fed with AIN-93G formula diet.The mice were sacrificed at the age of 9 months.The livers were weighed and the growth of liver cancer was observed and recorded.Results All the mice in the cereal-based diet group developed HCC as expected.The body weight and liver mass of the mice in the AIN-93G diet group were significantly lower than that of the cereal-based diet group.The incidence of HCC,and the number and size of tumor nodules were also significantly lower in the AIN-93G diet group than that in the cereal-based diet group.Conclusions DEN-induced HCC model has been successfully established in mice fed with cereal-based diet,while mice fed with AIN93-G diet prevented the development of DEN-induced HCC,and their body weight was decreased significantly,suggesting that dietary factors play a key role in establishment of animal disease models.
RESUMO
Objective To investigate the role of macrophage?derived Act1 (nuclear factor kappa B activator 1) in the inflammatory bowel disease. Methods Genetically engineered mice carrying targeted suppression of Act1 in the mac?rophages (Anti?Act1) were used for the dextran sodium sulfate (DSS)?induced ulcerative colitis. The severity of colitis was assessed by weight loss, stool consistency, fecal blood index, colorectal length and H&E histology. The infiltration of CD45 + leukocytes and CD68 + macrophages in the inflammatory intestine was observed by immunohistochemical staining and expression levels of mRNA for inflammatory cytokines in colon tissues were analyzed by RT?qPCR. Results As com?pared with C57 mice, the anti?Act1 mice exhibited less severe acute colitis following DSS treatment, with reduced CD45 +leukocyte and CD68 + macrophage infiltrates in the colon tissue. Inflamed colons of the anti?Act1 mice expressed lower mR?NA levels of TNF?α, IL?1βand IL?6. Conclusions Targeted suppression of Act1 in the macrophages ameliorates dextran sodium sulfate?induced intestinal inflammation.
RESUMO
OBJECTIVE@#To determine clinical features and diagnostic methods for primary tracheobronchial amyloidosis (TBA). @*METHODS@#The clinical manifestations and diagnosis of a male patient who had been misdiagnosed for many years were described and analyzed. @*RESULTS@#The patient was a 68-year-old male who complained of recurrent cough, expectoration, and progressive dyspnea for more than 30 years. He had been diagnosed with chronic bronchitis, bronchiectasis, and endobronchial tuberculosis in other hospitals and treated with antibiotics frequently and anti-tubercular agents for 3 months. Despite the treatments, the patient's symptoms were progressively worse. Finally, he came to Xiangya Hospital, Central South University, and was clearly diagnosed with primary TBA based on histopathological evidence after bronchoscopy. @*CONCLUSION@#TBA, a rare disease resulting from abnormal submucosal amyloid deposition in the trachea and bronchi, may display with many different symptoms. TBA is often misdiagnosed with other pulmonary diseases. The use of bronchoscopic techniques is essential for the diagnosis of TBA. Histopathology remains the gold standard for diagnosis of primary TBA. So, for patients with chronic cough of unknown etiology, bronchoscopy should be performed to obtain biopsy samples for the definitive diagnosis.
