Objective:To study the glypican 3 (GPC3) fluorescent probe imagings in hepatocellular carcinoma (HCC) tissues and to determine its prognostic value in HCC patients.Methods:The data of 87 patients who were treated at the Affiliated Hospital of Southwest Medical University from January 2019 to August 2020 were retrospectively analyzed. There were 75 males and 12 females, with the age of (56.1±11.9) years. The expressions of GPC3 were measured by immunohistochemistry and by the fluorescent probe. The results obtained by these two tests were compared. Patients were followed up for recurrence after hepatectomy. Univariate and multivariate Cox regression analyses were used to analyze factors influencing recurrence-free survival.Results:Detection of the GPC3 expression by GPC3 fluorescence probe was consistent with the results obtained by immunohistochemical studies ( Kappa=0.84, P<0.001). The positive rates of GPC3 fluorescent probe was 79.3%(69/87), compared with 80.4%(70/87) by immunohistochemistry studies, with no significant difference between the two groups ( P>0.05). The patients were then divided into the low differentiation group ( n=30) and the middle high differentiation group ( n=57) by the degrees of tumor differentiation. The fluorescence intensity in the low differentiation group was 134.4(128.0, 144.7) a. u. which was significantly different from the middle high differentiation group of 84.8(0, 108.5)a.u. ( Z=-7.52, P<0.001). The median fluorescence intensity of 87 patients with HCC was 108.6 a. u.. Multivariate Cox regression analysis showed that patients with a GPC3 fluorescence intensity ≥108.6 a. u. ( HR=2.07, 95% CI: 1.21-3.53, P=0.008) had a significant increased risk of recurrence after hepatectomy. Conclusion:The expressions of GPC3 in HCC were consistent between the studies by using either a GPC3 specific fluorescent probe or immunohistochemistry studies. A GPC3 fluorescence intensity ≥108.6 a. u. was a risk factor of recurrence after hepatectomy in patients with HCC.

OBJECTIVE: To delineate the nature and origin of a chromosomal aberration detected in a boy with mental retardation. METHODS: The proband and his parents were subjected to routine G-banded chromosomal karyotyping and single nucleotide polymorphism array (SNP-array) analysis. RESULTS: The karyotype of the proband was determined as 46, XX, add(8)(p23). No karyotypic abnormality was detected in either of his parents. SNP-array has identified a 34.9 Mb duplication at 8p23.1q11.1 and a 6.78 Mb microdeletion at 8p23.1pter in the proband. No copy number variation was detected in either parent. CONCLUSION The child was diagnosed with 8p inverted duplication deletion syndrome, which might be induced by non-allelic homologous recombination between olfactory genes in the 8p23.1 region.

To investigate the protective effect of the seed oil of Abelmoschus esculentus on gastric ulcer,two acute gastric ulcer mice models were established by intragastric administration of aspirin or absolute ethanol,respectively.Clinical index of ulcer area,ulcer index,gastric volume,gastric pH value,free acidity,total acidity,and histopathological assessment were measured to evaluate the injuries of gastric ulcer and the protective effect of okra seed oil In order to comprehensively uncover the possible underlying mechanism,a series of biochemical assays were also performed,including serum TNF-α,IL-6,IL-10 and Tbil,NO,MPO and SOD in the stomach included.Moreover,the ALT,AST and ALP in the liver of mice were also tested to evaluate the possible hepatic toxicity of the seed oil.The results indicated that the seed oil of A.esculentus exerted protective effect in ethanol-induced gastric ulcer mice by reducing the ulcer area and ulcer index,declining the free and total acidity,and increasing the pH value of gastric content.Histopathological observation showed the gastric mucosa of the acute gastric ulcer mice induced by alcohol was incomplete and severely damaged,with submucosal edema and nuclear pyknosis,as well as glandular structure disappearing,compared with that of normal mice.What's more,a number of inflammatory cell infiltration occured in the gastric mucosa of alcohol-model mice,with messes of neutrophils,lymphocytes,eosinophils and plasma cells.Okra seed oil could improve the damaged structure of the gastric mucosa and gland caused by ethanol,but could not ameliorate the condensation of nucleus and infiltration of inflammatory cells.Biochemical analysis revealed that the seed oil of A.esculentus could counteract the damage induced by ethanol via decreasing Tbil and TNF-α in serum,decreasing NO and myeloperoxidase,and increasing SOD in stomach.Meanwhile,okra seed oil exhibited protective effect in aspirin-induced gastric ulcer mice by increasing the gastric content pH,and reducing free and total acidity.Compared with the control group,the gastric mucosa of aspirin-model group showed multifocal coagulation necrosis,sheet edema and infiltration of inflammatory cells by histopathological assessment.Compared with the aspirin-model group,the soybean oil group and okra seed oil group could ameliorate the inflammatory cell infiltration.Biochemical analysis revealed that okra seed oil could counteract the injury induced by aspirin via decreasing TNF-α and IL-6,and increasing IL-1O in serum,decreasing NO and MPO and increasing SOD in stomach.In a word,the okra seed oil exerted protective effect on acute gastric ulcer by anti-inflammation,anti-oxidation and hepatocyte protection.The okra seed oil deserves further development and utilization.

Objective To assess the value of apparent diffusion coefficient (ADC)map with low b-value to monitor the ablated tissue after high-intensity focused ultrasonic (HIFU)treatment for uterine fibroids.Methods 25 patients with 34 uterine fibroids were treated with HIFU.All patients underwent the routine MRI scans (including pre-and post-contrast scanning)and monoexponential model DWI with b values of 150,600 and 1 000 s/mm2 before the surgery and within 24 hours after the surgery.The mean ADC values with different b-values of the ablated and non-ablated tissues between pre-and post-treatment were analyzed by one-way ANOVA test.The consistency of the ablation area between ADC maps with different b-values and contrast enhancement MRI were evaluated. Results With the b-value of 150 s/mm2 ,the mean ADC value of the ablated tissue was (1.48±0.27)×10-3 mm2/s,which was less significantly than that of pre-treatment (2.06±0.21)×10-3 mm2/s and non-ablated tissue (1.98±0.23)×10-3 mm2/s (P<0.05). However,there were no significant differences in ADC values with the b values of 600 s/mm2 and 1 000 s/mm2 among those areas (P>0.05).A fine consistency of the ADC map with the low b-value (150 s/mm2 )was found with non-perfusion volume on contrast-enhanced T1 WI,which was superior to that with high b-values (600 s/mm2 and 1 000 s/mm2 )(P<0.05).Conclusion ADC map with low b-value (150 s/mm2 )can be used to evaluate the blood-supply changes and ablated volume of uterine fibroids indirectly,which helps to assess the treatment effect of HIFU.

Objective To study the prevalence and characteristics of gastroesophageal reflux disease (GERD) in patients with idiopathic pulmonary fibrosis(IPF).Methods A total of 48 patients with diffuse parenchymal lung disease(DPLD) including 25 IPF and 23 other DPLD were enrolled from Department of Respiratory Disease in the First Affiliated Hospital of China Medical University.All patients were subjected to 24-hour esophageal pH monitoring.Pulmonary function test and HRCT of lung were performed at the same time.Results The prevalence of GERD in IPF patients was 64.0％,which was significantly higher than that in other DPLD patients.DeMeester scores were significantly higher in IPF patients than those in non-IPF group[(22.8 ± 21.5) score vs (15.7 ± 14.0) score respectively P ＜ 0.05].Numbers of reflux longer than 5 minutes [(3.8 ± 4.1) time vs (2.1 ± 2.1) time respectively) and reflux index (1.8 ± 1.7 vs 1.3 ± 1.2) in IPF group were higher than those in non-IPF group,yet without statistical significance.Patients with IPF had significantly higher values of following parameters than those in non-IPF patients including percentage of total reflux time(pH ＜ 4.0) (9.2 ± 5.1) ％,percentage of upright reflux time (8.5 ± 5.2) ％,percentage of supine reflux time (10.8 ± 10.7) ％,numbers of reflux (54.2 ± 22.7) time,numbers of regurgitation longer than 5 minutes (6.3 ± 4.2) time,thelongest reflux time (14.5 ± 15.3) min,reflux index 2.5 ± 1.7 and DeMeester scores (34.9 ± 20.3) time (P ＜ 0.05).DeMeester score was positively correlated with gastroesophageal reflux diseases questionnaire (GerdQ) score (r =0.667,P ＜ 0.01).The prevalence of typical GERD sympotoms in the IPF-GERD patients was higher (heartburn 7/16,regurgitation 6/16) than that in IPF patients without GERD (heartburn 2/9,regurgitation 1/9).Conclusion Patients with IPF have a high prevalence of GERD,but usually without typical GERD symptoms.In the hospitals 24-hour esophageal pH monitoring not available,GerdQ can be used to identify GERD in IPF patients.

In order to evaluate the effect and mechanism of the mulberry leaf alkaloid, flavones, and polysaccharide intervention on diabetes, the overall metabolite profiling characteristics for the plasma of diabetic mouse was performed by using an ultra-performance liquid chromatography/electrospray-tandem mass spectrometry (UPLC-ESI-MS). The 8 potential biomarkers were found in diabetic mice plasma based on the data of MS/MS characteristics obtained from the UPLC-OrbitrapMS analysis, which mainly involved in sphingolipids, amino acid metabolic pathway. The principal component analysis showed that the normal group and model group were obviously distinguished and implied that metabolic disturbance was happened in diabetic mice plasma. The extracts of mulberry leaf flavonoids, polysaccharide, alkaloid had exhibited the effects of callback function for diabetic mice through regulating the amino acid metabolism and sphingolipid metabolism.

The study aims to screen the ability of the bacteria to metabolize ononin and assess the effect of ononin on the intestinal bacteria. Fresh human fecal sample was obtained from a healthy volunteer, diluted serially in sterile water and sixty-nine different bacterial colonies were picked out ultimately. UPLC-Q-TOF/MS with automated data analysis software (MetaboLynx) was applied to fast analysis of ononin metabolites. Furthermore, an E(max) precision microplate reader was employed to determine the growth situation of Enterococcous sp., Enterobacter sp., Lactobacilli sp., and Bifidobacteria sp. Results indicated that hydrogenation, demethylation, hydroxylation and deglycosylation were the major metabolic pathways of ononin by human intestinal bacteria in vitro. Ononin can inhibit the growth of pathogen such as Enterococcus sp., Enterobacter sp. and can promote the growth of probiotics such as Bifidobacteria sp. and Lactobacilli sp. This study suggested that intestinal bacteria have the metabolic effects of ononin and the biotransformation was completed by different bacteria. And ononin can affect the balance of intestinal flora and the degree of influence varies depending on the bacterial species and the concentration of ononin.

Five patients' follow-up scan showed decreased or disappeared abnormal signals. Conclusion MRI examination scan identify the location, quality and degree, meanwhile, analyze the pathological foundation of postpartum PRES, which conduces to guiding treatment and preventing complication.

Objective To investigate the expression of Tie-2 in rectal carcinoma and its relationship with invasion and metastasis in rectal carcinoma. Materials S-P immunohistochemical assay was used to detect the expression of Tie-2 in 40 cases of rectal carcinoma and 10 cases of normal rectal tissues. Results Tie-2 was mainly localized in the cytoplasm and nucleus of vascular endothelial cells in cancerous tissues and partly in the cytoplasm of some cancerous cells. The expression of Tie-2 in rectal carcinoma was significantly higher than that in normal rectal tissues (P<0.05); however, Tie-2 expression was not associated with differentiation, invasion depth and Dukes stage (P>0.05), but with lymphatic metastasis (P<0.05). Conclusion Tie-2 plays a key role in carcinogenesis and lymph node metastasis of rectal carcinoma.
