ABSTRACT
Objective To explore specific magnetic resonance imaging(MRI)features of somatic symptoms in depression by comparing the differences of brain gray matter volume in depression patients with and without somatic symptoms using voxel-based morphometry(VBM).Methods A total of 52 depression patients were recruited and divided into somatic and no somatic symptoms group according to the patient health questionnaire-15 score(＞9 and≤9,respectively).Forty gender-age-matched healthy volunteers were recruited as the control group.All subjects underwent MRI scanning.Imaging data were analyzed to explore the differences in brain gray matter between groups using VBM.Results Compared with control group,gray matter volume increased in the right superior temporal gyrus,and decreased in the right inferior orbitofrontal gyrus,right inferior temporal gyrus,left inferior orbitofrontal gyrus,and left superior temporal gyrus for depressive patients with somatic symptoms(P＜0.001);gray matter volume increased in the right middle temporal gyrus,and decreased in the right superior temporal gyrus and right inferior temporal gyrus for depressive patients without somatic symptoms(P＜0.001).Only the volume in the right tongue and left cingulate gyrus increased in depressive patients with somatic symptoms compared with that in patients without somatic symptoms(P＜0.01).Conclusion VBM-MRI has demonstrated increased volume in the tongue and cingulate gyrus in the somatic symptoms of depression.
ABSTRACT
Objective:To evaluate the long-term risk of rebleeding in patients with acute esophageal and gastric variceal bleeding and portal vein thrombosis after endoscopic treatment in liver cirrhosis.Methods:From January to December 2022, 57 patients with acute esophageal and gastric variceal bleeding who were treated by endoscopy in the emergency department of the Zhongshan Hospital affiliated to the Fudan University were included in the study. According to the results of portal vein CT angiography (CTA), the patients were divided into thrombosis group and non thrombosis group. We compared the basic information and endoscopic treatment status of two groups of patients. All patients were followed up until 1 year after endoscopic treatment or April 15, 2023, and re bleeding and survival were recorded during the follow-up period. The influencing factors of rebleeding after 1 year of treatment were analyzed.Results:The patient′s age was (55.9±11.4)years old, mainly male [78.95%(45/57)]. The average time from initial bleeding to endoscopic treatment for all patients was (6.6±2.8)days. There was no statistically significant difference between the two groups in terms of age, sex, combined liver malignancy, Child-pugh score, first bleeding form, ascites, and first laboratory examination results (including hemoglobin, platelet, Prothrombin time, creatinine) (all P>0.05). There was no statistically significant difference in the history of endoscopic treatment, bleeding distance from endoscopic treatment, the proportion of patients with esophageal varices and gastric varices, the proportion of patients with esophageal varices treated with ligation, and the proportion of patients with gastric varices treated with tissue glue between the two groups (all P>0.05). A total of 2 patients died after surgery, and 12 patients experienced rebleeding, including 10 in the thrombotic group and 2 in the non thrombotic group. Kaplan Meier analysis showed that the 1-year rebleeding rate in the thrombotic group was significantly higher than that in the non thrombotic group (59.02% vs 24.71%, RR=6.002, 95% CI: 1.06-34.00, P=0.020 8). Cox multivariate regression analysis suggests that the presence of portal vein thrombosis ( HR=7.669, 95% CI: 1.453-40.472, P=0.016) was an independent risk factor for recurrent bleeding after endoscopic treatment of acute esophageal and gastric variceal bleeding for one year. Conclusions:Portal vein thrombosis in liver cirrhosis increases the risk of recurrent bleeding after endoscopic treatment for acute esophageal and gastric variceal bleeding for one year. For patients with acute Upper gastrointestinal bleeding complicated with portal vein thrombosis, regular endoscopic and ultrasonic follow-up, individualized endoscopic sequential and selective anticoagulation therapy should be carried out.
ABSTRACT
Adrenal epithelioid sarcoma is very rare in clinic. A case of epithelioid sarcoma of the right adrenal gland was reported in this paper. After physical examination, the patient was found to have a mass in the right adrenal area and underwent right adrenalectomy. The postoperative pathological diagnosis was right adrenal epithelioid sarcoma. Two months after adrenalectomy, positron emission tomography computed tomography(PET/CT) noted recurrence at the tumor bed and multiple metastases.The patient underwent chemotherapy combined with immunotherapy. After 16 months of follow-up, the disease was stable.
ABSTRACT
Pulmonary endothelial barrier dysfunction is a hallmark of clinical pulmonary edema and contributes to the development of acute lung injury (ALI). Here we reported that ruscogenin (RUS), an effective steroidal sapogenin of Radix Ophiopogon japonicus, attenuated lipopolysaccharides (LPS)-induced pulmonary endothelial barrier disruption through mediating non-muscle myosin heavy chain IIA (NMMHC IIA)‒Toll-like receptor 4 (TLR4) interactions. By in vivo and in vitro experiments, we observed that RUS administration significantly ameliorated LPS-triggered pulmonary endothelial barrier dysfunction and ALI. Moreover, we identified that RUS directly targeted NMMHC IIA on its N-terminal and head domain by serial affinity chromatography, molecular docking, biolayer interferometry, and microscale thermophoresis analyses. Downregulation of endothelial NMMHC IIA expression in vivo and in vitro abolished the protective effect of RUS. It was also observed that NMMHC IIA was dissociated from TLR4 and then activating TLR4 downstream Src/vascular endothelial cadherin (VE-cadherin) signaling in pulmonary vascular endothelial cells after LPS treatment, which could be restored by RUS. Collectively, these findings provide pharmacological evidence showing that RUS attenuates LPS-induced pulmonary endothelial barrier dysfunction by inhibiting TLR4/Src/VE-cadherin pathway through targeting NMMHC IIA and mediating NMMHC IIA‒TLR4 interactions.
ABSTRACT
Objective:To investigate the correlation between thromboelastography (TEG) and portal vein thrombosis in patients with cirrhotic esophagogastric varices.Methods:210 hospitalized patients with cirrhotic esophagogastric varices treated in Zhongshan Hospital Affiliated to Fudan University from December 2016 to December 2017 were retrospectively included. They were divided into portal vein thrombosis group (PVT group) and non portal vein thrombosis group (NPVT group) according to whether they were complicated with portal vein thrombosis. The correlation between the results of TEG coagulation reaction time (R value), coagulation time (K value), αAngle, maximum amplitude (MA) and coagulation composite index (CI) and portal vein thrombosis was analyzed. The characteristics of coagulation status in patients with portal vein thrombosis in cirrhosis were compared.Results:A total of 91 patients (43.3%) were complicated with portal vein thrombosis. The R value in the PVT group was significantly lower than that of NPVT group [5.49(5.22-5.77) vs 5.98(5.76-6.20), P=0.006]. Logistic regression analysis showed that Child Pugh grade ( OR=2.883, 95% CI: 1.630-5.098, P<0.001) and R value ( OR=0.739, 95% CI: 0.575-0.950, P=0.018) were independently associated risk factors of PVT. The R value of patients was significantly correlated with Child Pugh grade ( r=0.147, P=0.034), platelet ( r=-0.358, P<0.001), prothrombin time (PT) ( r=0.334, P<0.001) and international standardized ratio (INR) ( r=0.328, P<0.001). Conclusions:The decrease of TEG-R value is closely related to PVT in liver cirrhosis.
ABSTRACT
Objective:This study aimed to evaluate the rebleeding risk and prognosis of patients being treated after acute esophageal varices bleeding by two different treatment strategies: sclerosing agent combined with tissue glue injection, esophageal varices ligation (EVL), through comparing the therapeutic effects and securities.Methods:A total of 76 patients who underwent endoscopy and received treatment in Zhongshan Hospital Affiliated to Fudan University due to acute esophageal variceal bleeding were included retrospectively. 6 patients with active bleeding and 70 patients with thrombus in esophagus varices under gastroscopy. Among them, 21 cases were treated with sclerosing agent combined with tissue glue injection (sclerosing tissue glue group), and 55 cases were treated with EVL (EVL group). The emergency endoscopic diagnosis and treatment of the two groups were compared, and the risk factors of rebleeding 6 months after endoscopic treatment were analyzed by univariate and multivariate analysis.Results:All patients received endoscopic treatment successfully. During the follow-up period of 6 months after endoscopic treatment, rebleeding occurred in 13 cases. Kaplan Meier analysis showed that the 6-month rebleeding rate in the sclerosing tissue glue group was significantly higher than that in the EVL group (41.6% vs 12.3%, P=0.011). There were 8 deaths in total. Kaplan Meier analysis showed that there was no significant difference in 6-month mortality between the two groups (17.5% vs 10.1%, P=0.616). Multivariate analysis further showed that malignant tumor ( HR=3.700, 95% CI: 1.187-11.536, P=0.024) and treatment mode of esophageal variceal bleeding ( HR=4.834, 95% CI: 1.443-16.193, P=0.011) were independent risk factors for rebleeding 6 months after endoscopic treatment of acute esophageal variceal bleeding. Conclusions:This study found that EVL and the combining injection of lauromacrogol and cyanoacrylate could be used in emergent hemostatic treatment for acute esophageal varices bleeding. Moreover, EVL is the prioritized approach in endoscopic emergency treatment with a lower rebleeding rate and fewer complications. Sclerotherapy combined with tissue glue can be used as one of the measures of emergency treatment, which is not better than ligation.
ABSTRACT
Objective:In this study, the liver, spleen, and hepatic portal vein in the portal venous phase images of abdominal enhanced computed tomography (CT) are artificially segmented and annotated, and the radiomics features are extracted from them. A model for predicting portal pressure in patients with hepatitis B virus (HBV) related cirrhosis is constructed by combining radiomics features with clinical indicators.Methods:A total of 171 patients who had abdominal enhancement CT examination and trans-jugular hepatic venous pressure gradient (HVPG) measurement at the same time were enrolled from January 2016 to May 2020 in the Zhongshan Hospital Affiliated to Fudan University. The liver, spleen, and hepatic portal vein in the portal venous phase images of the CT were manually labeled by using ITK-SNAP 3.8 software. The radiomics features of these three sites were extracted using Python programming, and an HVPG prediction model was established.Results:A total of 171 patients was included in the study. The average age was (51.1±10.3)years, of which 134(78.4%) were males, and the average HVPG was 16.87±5.695. A total of 2 553 radiomics features were extracted from three sites of the portal venous phase images of abdominal enhanced CT in each patient. The 2 553 features extracted were screened using LASSO, and by combing with clinical features and radiomics features, the predictive model of HVPG was obtained: m_HVPG=31.622+ 0.028 8T×total bile acids-6.31(portal venous wavelet-LHH_glcm_ClusterShade)=0.253(portal venous wavelet-LHL_glszm_LargeAreaLowGrayLevelEmphasis)-20.9(spleen wavelet-LLH_glcm_Correlation)-0.000 127(liver original_shape_SurfaceArea)+ 2.79(liver wavelet-LLH_glcm_ClusterShade). The coefficient of determination R2 was 0.345. Conclusions:The study suggests that radiomics features of the liver, spleen, and portal venous combined with clinical features may be used as a non-invasive method to assess the portal pressure in patients with HBV-related cirrhosis.

ABSTRACT
Objective:The aim of this study was to investigate the prognostic value of vitamin B12 as the non-invasive biomarker to predict long-term rebleeding rate in cirrhotic patients with esophagogastric varices.Methods:From Dec 1, 2016 to Dec 31, 2017, cirrhotic patients with esophagogastric varices who had been admitted to Zhongshan Hospital affiliated to Fudan University were enrolled. All these patients received endoscopic treatment to prevent variceal rebleeding. The serum vitamin B12 and folic acid levels were measured in all of them. The receiver operating characteristic (ROC) analysis, Kaplan-Meier analysis, univariate and multivariate cox regression analysis were conducted to explore the value of vitamin B12 in predicting 3-year variceal rebleeding in cirrhotic patients with esophagogastric varices after endoscopic treatment.Results:115 patients were included. The ROC curve analysis indicated that the optimal cutoff value of vitamin B12 for 3-year variceal rebleeding was 567.25 pg/ml. According to the cut-off value, the patients were divided into high-level vitamin B12 group ( n=49) and low-level vitamin B12 group ( n=66). Compared with the low vitamin B12 group, the high vitamin B12 group had lower albumin level, less male (63.3% vs 80.3%), and higher 3-year rebleeding rate ( P<0.05). Cox analysis showed that vitamin B12 and platelet were independent prognostic factors for 3-year rebleeding in patients with variceal bleeding. Conclusions:Elevated peripheral blood vitamin B12 predicts a higher risk of long-term rebleeding in patients with liver cirrhosis and esophagogastric varices.
ABSTRACT
Objective To compare and analyze the main manifestations of HIV/ AIDS impact on marriage and family structure.Methods The relevant data of 931 HIV households and 995 non-HIV households were collected in five provinces with high HIV prevalence in China,using the method of questionnaire survey.The differences between people living with HIV/ AIDS(PLWHA)and non-HIV individuals in marriage and family structure were analyzed and compared.Results The percentage of PLWHA who were unmarried,divorced,widowed and remarried was higher than that of individuals in non-HIV households;the average size of the non-HIV households was 4.4 persons,while the size of HIV households was 4.0 persons;of the surveyed HIV households 41.1 % were stem families,while in the case of non-HIV households this percentage was lower,only 33.4 %.The rate of school enrollment among children in HIV households was lower than that in non-HIV households,while the rate of labor participation among the elderly in HIV households was higher than that in non-HIV households.Conclusion The results indicate that HIV/AIDS destroys the normal marriage among PLWHA,leading to an increased number of stem families and changes in family structure;the impact on the elderly and children in the HIV households is severe.All this means that HIV/AIDS weakens or even destroys the family function.
