Reduction of portosystemic gradient during transjugular intrahepatic portosystemic shunt achieves good outcome and reduces complications.

BACKGROUND: Transjugular intrahepatic portosystemic shunt (TIPS) is placed important role in the therapy of complications of portal hypertension, there is still no suitable criterion for a reduction in portosystemic gradient (PSG), which can both reduce PSG and maximize clinical results and minimize hepatic encephalopathy (HE). AIM: To compare the clinical outcomes and incidence of HE after one-third PSG reduction during TIPS in patients with variceal bleeding and refractory ascites. METHODS: A total of 1280 patients with portal-hypertension-related complications of refractory ascites or variceal bleeding who underwent TIPS from January 2016 to January 2019 were analyzed retrospectively. Patients were divided into group A (variceal hemorrhage and PSG reduced by one third, n = 479); group B (variceal hemorrhage and PSG reduced to < 12 mmHg, n = 412); group C (refractory ascites and PSG reduced by one third, n = 217); and group D (refractory ascites and PSG reduced to < 12 mmHg of PSG, plus medication, n = 172). The clinical outcomes were analyzed. RESULTS: By the endpoint of follow-up, recurrent bleeding was no different between groups A and B (χ 2 = 7.062, P = 0.374), but recurrent ascites did differ significantly between groups C and D (χ 2 = 14.493, P = 0.006). The probability of total hepatic impairment within 3 years was significantly different between groups A and B (χ 2 = 11.352, P = 0.005) and groups C and D (χ 2 = 13.758, P = 0.002). The total incidence of HE differed significantly between groups A and B (χ 2 = 7.932, P = 0.016), groups C and D (χ 2 = 13.637, P = 0.007). There were no differences of survival rate between groups A and B (χ 2 = 3.376, P = 0.369, log-rank test), but did differ significantly between groups C and D (χ 2 = 13.582, P = 0.014, log-rank test). CONCLUSION: The PSG reduction by one third may reduce the risk of HE, hepatic function damage and achieve good clinical results.

Prognostic value of hysterosalpingography after salpingostomy in patients with hydrosalpinx.

To assess whether post-hysterosalpingography evaluation was associated with pregnancy rate and to identify independent risk factors for pregnancy success after salpingostomy in patients with hydrosalpinx. A retrospective analysis was conducted on the clinical data of 47 patients diagnosed with hydrosalpingography (HSG) in our hospital from 2015 to 2018. These patients received laparoscopic surgery and another salpingography within 2 months after surgery. According to the fallopian tube conditions evaluated by HSG before and after surgery, the patients could be divided into two groups. According to the pregnancy rate and postoperative HSG of patients with hydrosalpinx after laparoscopy, the total pregnancy rate of the tubal improved group was 65.62%, while that of the non-improved group was 20%, with statistical significance (p < 0.05). We found that hysterosalpingography after salpingostomy in patients with hydrosalpinx can provide reference for clinical treatment and improve the prognosis of patients.

Postoperative HSG improvement was an independent risk factor for pregnancy rate in patients with hydrosalpinx after laparoscopic surgery. Impact statementWhat is already known on this subject? Fallopian tube obstruction is an important cause of female infertility. Current studies have shown that most spontaneous pregnancies in patients with hydrosalpinx after salpingostomy occur within 18 months, however, pregnancy rates and outcomes vary from report to report.What do the results of this study add? Many studies have shown that hydrosalpinx reduces the success rate of natural pregnancy and embryo transfer, but the mechanism of hydrosalpinx affecting pregnancy remains unclear. This study explored the mechanism of successful pregnancy through hysterosalpingography after salpingostomy in patients with hydrosalpinx.What are the implications of these findings for clinical practice and/or further research? To evaluate the prognosis of patients with hydrosalpinx after laparoscopic salpingostomy by hysterosalpingography (HSG), and to reflect the improvement according to the postoperative pregnancy rate of the patients. To provide clinical personalized treatment plan.

Salivary cytokine profile in patients with oral lichen planus.

BACKGROUND/PURPOSE: Oral lichen planus (OLP) is a chronic inflammatory lesion of oral mucosal, and its pathogenesis involves immune cell-mediated aberrances. However, the findings conflict with each other. This research aimed to comprehensively detect the salivary cytokine profile of patients with OLP. MATERIALS AND METHODS: The cohort included 60 OLP patients (30 reticular and 30 erosive), and 30 healthy controls, matched in age and sex. Human Cytokine/Chemokine Magnetic Bead Panel Kit (HCYTMAG-60K-PX41) was used to detect salivary inflammation-related cytokines. Rank sum test, group t-test, and ANOVA were used for data analysis in different groups. Moreover, Spearman's rank correlation analysis was used to analyze the correlation between salivary cytokine levels and OLP lesion severity. RESULTS: The levels of TNF-α, G-GSF, IL-1α, IL-1ß and IL-8 were statistically significant higher in both erosive and reticular OLP patients than in the healthy group, while the IL-13 level was significantly lower. Particularly, the salivary TNF-α, GM-CSF, MIP-1α, MIP-1ß, IL-1ß, IL-6 and IL-8 levels were higher in erosive OLP group than other groups. Spearman's rank correlation analysis revealed that the salivary TNF-α, GM-CSF, MIP-1α, MIP-1ß, IL-1ß and IL-6 levels were positively correlated with OLP lesion severity. CONCLUSION: Imbalance of the Th1/Th2-mediated immune response contributes to OLP. Certain salivary cytokines, such as MIP-1α, MIP-1ß, GM-CSF, and IL-6, are positively correlated with OLP severity, and they have a high potential as biomarkers to diagnose and predict OLP prognosis.

Characteristics of Peripheral Lymphocyte Subsets in Patients With Acute-On-Chronic Liver Failure Associated With Hepatitis B.

Background and Aims: Acute-on-chronic liver failure (ACLF) is a rare, but dramatic clinical syndrome. There is substantial evidence suggesting that immunity-mediated inflammation plays an important role in HBV-ACLF. Our aim was to characterize the proportion and cell counts of peripheral blood lymphocyte subsets in acute-on-chronic liver failure patients caused by HBV infection. Methods: One hundred and seventeen patients were enrolled in this study, including those with HBV-related ACLF (HBV-ACLF; n = 70), and HBV related non-ACLF patients (HBV non-ACLF; n = 47). Demographics, clinical and laboratory data at hospital admission were retrospectively analyzed. The percentage and cell count of peripheral lymphocyte subsets were evaluated by flow cytometry. Comparison analysis was performed by t-test or non-parametric Mann-Whitney U-test. Actuarial probabilities of death were calculated by the Kaplan-Meier method. Results: Both circulating lymphocyte count and lymphocyte percentage were significantly reduced in patients with HBV-ACLF (P < 0.001). The CD8+ T cell, CD4+ T cell, and CD16+CD56+ NK cell counts were significantly decreased in HBV-ACLF. Consistently, flow cytometric analysis showed that CD8+ T cell counts were significantly decreased in non-survivors, while no significant differences were found in CD4+ T cell, CD19+ B cell, or CD56+CD16+ NK cell counts. Furthermore, the group with the lower CD8+ T cell count displayed a significantly higher mortality rate compared with the group with the higher CD8+ T cell count. Conclusions: The abnormal prevalence of lymphocyte subsets may be important in the pathogenesis of HBV-ACLF. The decrease in CD8+ T cell counts may be related to poor survival in HBV-ACLF patients.

Overview of bile acid signaling in the cardiovascular system.

Bile acids (BAs) are classically known to play a vital role in the metabolism of lipids and in absorption. It is now well established that BAs act as signaling molecules, activating different receptors (such as farnesoid X receptor, vitamin D receptor, Takeda G-protein-coupled receptor 5, sphingosine-1-phosphate, muscarinic receptors, and big potassium channels) and participating in the regulation of energy homeostasis and lipid and glucose metabolism. In addition, increased BAs can impair cardiovascular function in liver cirrhosis. Approximately 50% of patients with cirrhosis develop cirrhotic cardiomyopathy. Exposure to high concentrations of hydrophobic BAs has been shown to be related to adverse effects with respect to vascular tension, endothelial function, arrhythmias, coronary atherosclerotic heart disease, and heart failure. The BAs in the serum BA pool have relevant through their hydrophobicity, and the lipophilic BAs are more harmful to the heart. Interestingly, ursodeoxycholic acid is a hydrophilic BA, and it is used as a therapeutic drug to reverse and protect the harmful cardiac effects caused by hydrophobic elevated BAs. In order to elucidate the mechanism of BAs and cardiovascular function, abundant experiments have been conducted in vitro and in vivo. The aim of this review was to explore the mechanism of BAs in the cardiovascular system.
