ObjectiveTo investigate the influencing factors for rebleeding and 5-year survival rate after treatment in patients with liver cirrhosis and spontaneous splenorenal shunt （SSRS）， and to provide a basis for clinical prognostic assessment. MethodsA total of 95 patients with liver cirrhosis and SSRS who were admitted to Zhongshan Hospital and Xiamen Branch of Fudan University from June 2014 to June 2018 were enrolled， and all patients were followed up for at least 5 years. According to the presence or absence of gastrointestinal bleeding during follow-up， the patients were divided into rebleeding group with 27 patients and non-rebleeding group with 68 patients. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous between two groups， and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups. Univariate and multivariate Cox regression analyses were used to investigate the influencing factors for the prognosis of patients with SSRS， and the Kaplan-Meier method was used to describe survival outcomes. A Pearson or Spearman correlation analysis was performed. ResultsCompared with the non-rebleeding group， the rebleeding group had significantly higher splenorenal shunt diameter ［4.60（3.20 ‍—‍ 5.90） mm vs 3.45（2.10 ‍—‍ 5.45） mm， Z=1.973， P=0.048］ and hepatic venous pressure gradient（18.57±6.60 mmHg vs 15.06±5.82 mmHg， t=2.280， P=0.026） and a significantly lower portal vein diameter（14.04±2.90 mm vs 15.45±2.90 mm， t=2.138， P=0.035）. The correlation analysis showed that splenorenal shunt diameter was negatively correlated with portal vein diameter（rs=-0.211， P=0.040）. Adverse events within 5 years after treatment included rebleeding（27.4%）， portal vein thrombosis（11.6%）， infection（4.2%）， cerebral hemorrhage（1.1%）， and cerebral infarction（1.1%）. Splenorenal shunt diameter（risk ratio ［RR］=1.173， 95% confidence interval ［CI］： 1.001‍ ‍—‍ ‍1.374， P=0.048） and superior mesenteric vein diameter（RR=0.844， 95%CI： 0.746 ‍—‍ 0.956， P=0.007） were independent influencing factors for gastrointestinal rebleeding within 5 years after treatment. Bilirubin（RR=1.028， 95%CI： 1.010 ‍—‍ 1.046， P=0.002） and blood urea nitrogen（RR=1.347， 95%CI： 1.116 ‍—‍ 1.625， P=0.002） were independent risk factors for 5-year survival rate after treatment. ConclusionSplenorenal shunt diameter is closely associated with the prognosis of cirrhotic patients， and it is recommended to enhance imaging follow-up of splenorenal shunt diameter for cirrhotic patients with SSRS.

lncRNA AC005224.4/miR-140-3p/SNAI2 regulating axis facilitates the invasion and metastasis of ovarian cancer through epithelial-mesenchymal transition / 中华医学杂志(英文版)

BACKGROUND@#Ovarian cancer is one of the most widespread malignant diseases of the female reproductive system worldwide. The plurality of ovarian cancer is diagnosed with metastasis in the abdominal cavity. Epithelial-mesenchymal transition (EMT) exerts a vital role in tumor cell metastasis. However, it remains unclear whether long non-coding RNA (lncRNA) are implicated in EMT and influence ovarian cancer cell invasion and metastasis. This study was designed to investigate the impacts of lncRNA AC005224.4 on ovarian cancer.@*METHODS@#LncRNA AC005224.4, miR-140-3p, and snail family transcriptional repressor 2 ( SNAI2 ) expression levels in ovarian cancer and normal ovarian tissues were determined using real-time quantitative polymerase chain reaction (qRT-PCR). Cell Counting Kit-8 (CCK-8) and Transwell (migration and invasion) assays were conducted to measure SKOV3 and CAOV-3 cell proliferation and metastasis. E-cadherin, N-cadherin, Snail, and Vimentin contents were detected using Western blot. Nude mouse xenograft assay was utilized to validate AC005224.4 effects in vivo . Dual-luciferase reporter gene assay confirmed the targeted relationship between miR-140-3p and AC005224.4 or SNAI2 .@*RESULTS@#AC005224.4 and SNAI2 upregulation and miR-140-3p downregulation were observed in ovarian cancer tissues and cells. Silencing of AC005224.4 observably moderated SKOV3 and CAOV-3 cell proliferation, migration, invasion, and EMT process in vitro and impaired the tumorigenesis in vivo . miR-140-3p was a target of AC005224.4 and its reduced expression level was mediated by AC005224.4. miR-140-3p mimics decreased the proliferation, migration, and invasion of ovarian cancer cells. SNAI2 was identified as a novel target of miR-140-3p and its expression level was promoted by either AC005224.4 overexpression or miR-140-3p knockdown. Overexpression of SNAI2 also facilitated ovarian cancer cell viability and metastasis.@*CONCLUSION@#AC005224.4 was confirmed as an oncogene via sponging miR-140-3p and promoted SNAI2 expression, contributing to better understanding of ovarian cancer pathogenesis and shedding light on exploiting the novel lncRNA-directed therapy against ovarian cancer.

Hepatitis B virus X protein promotes podocyte pyroptosis in hepatitis B virus-associated glomerulonephritis by down-regulating microRNA -223 targeting NLRP3 inflammasome / 中华肝脏病杂志

Objective: To investigate the potential function and related mechanism of microRNA-223 (miRNA-223) in the podocyte pyroptosis of hepatitis B virus (HBV)-associated glomerulonephritis induced by HBV X protein (HBx). Methods: HBx-overexpressing lentivirus was transfected into human renal podocytes to mimic the pathogenesis of HBV-GN. Real-time fluorescence quantitative PCR and Western blotting experiments were used to detect the mRNA and protein expression of pyroptosis-related proteins [nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3), apoptosis-associated speck-like protein containing a CARD (ASC) and caspase-1], and inflammatory factors (interleukin-1β and interleukin-18), respectively.TUNEL staining and flow cytometry were used to detect the number of pyroptosis cells. Immunofluorescence staining was used to detect the expression of podocytes biomarkers desmin and nephrin; Hoechst 33342 staining was used to observe the morphological and quantitative changes of podocyte nuclei. Enzyme-linked immunosorbent assay was used to measure caspase-1 activity. The dual luciferase reporter gene assay was used to verify the downstream target of miRNA-223. Podocytes were divided into the following nine groups: control group (no special treatment), empty plasmid group (transfected with empty plasmid), HBx overexpression group (transfected with HBx overexpression lentivirus), HBx overexpression+miRNA-223 mimic group (transfected with HBx overexpression lentivirus and miRNA-223 mimic), HBx overexpression+miRNA-223 inhibitor group (transfected with HBx overexpression lentivirus and miRNA-223 inhibitor), HBx overexpression+miRNA-223 mimic+NLRP3 group (transfected with HBx overexpression lentivirus, miRNA-223 mimic and NLRP3 overexpression plasmid), HBx overexpression+miRNA-223 mimic+ NLRP3 siRNA group (transfected with HBx overexpression lentivirus, miRNA-223 mimic and NLRP3 siRNA), HBx overexpression+miRNA-223 inhibitor+NLRP3 group (transfected with HBx overexpression lentivirus, miRNA-223 inhibitor and NLRP3 overexpression plasmid), HBx overexpression+miRNA-223 inhibitor+NLRP3 siRNA group (transfected with HBx overexpression lentivirus, miRNA-223 inhibitor and NLRP3 siRNA). Results: miRNA-223 was down-regulated in HBx overexpression group compared with the control group (P < 0.05). TUNEL and immunofluorescence staining showed that NLRP3 knockdown attenuated podocyte injury and pyroptosis induced by HBx overexpression (P < 0.05). Dual luciferase reporter gene assay demonstrated that NLRP3 was one of the downstream targets of miRNA-223. Rescue experiments revealed that NLRP3 overexpression weakened the protective effect of miRNA-223 in podocyte injury (P < 0.05). The addition of miRNA-223 mimic and NLRP3 siRNA decreased the expression of NLRP3 inflammasome and cytokines, and reduced the number of pyroptosis cells induced by HBx overexpression (all P < 0.05); The addition of miRNA-223 inhibitor and NLRP3 overexpression plasmid significantly increased the expression of NLRP3 inflammasome and cytokines, caspase-1 activity, and the number of pyroptosis cells (all P < 0.05). Conclusion: HBx may promote podocyte pyroptosis of HBV-GN via downregulating miRNA-223 targeting NLRP3 inflammasome, suggesting that miRNA-223 is expected to be a potential target for the treatment of HBV-GN.

The spread of herpes skin area: 2 cases involved too large area, 21 cases of 10 cm×10 cm, 14 cases of 5 cm×5 cm, 9 cases of 1 cm×1 cm. Herpes number: 26 cases had 10-49 herpes, followed by <10 herpes (n=9), uncountable herpes (n=7) and 50-99 herpes (n=4). The clinical course[M(Q1,Q3)] lasted 20.5 (13.5,24.8) d averagely, 5 cases had postherpetic neuralgia (PHN) and 1 case had respiratory complications. Shingles decrustation time was significantly shorter in vaccination group (Z=-2.01, P<0.05), and there was no significant difference in other characteristics by vaccination. In conclusion, the number and spread of shingles in most children and adolescents are less, and the complications such as PHN are less. Varicella vaccination can reduce the decrustation time and relieve shingles cases with some clinical symptoms.

Surveillance of adverse events following immunization with human papillomavirus vaccines in Hangzhou City from 2017 to 2021 / 预防医学

Objective@#To investigate the incidence of adverse events following immunization (AEFI) of human papillomavirus (HPV) vaccines in Hangzhou City from 2017 to 2021, so as to provide insights into safety monitoring and evaluation for HPV vaccines.@*Methods@#The AEFI caused by immunization of bivalent (HPV2), quadrivalent (HPV4) and nonavalent HPV vaccines (HPV9) reported in Hangzhou City from 2017 to 2021 were captured from the AEFI Surveillance Module of Chinese Disease Control and Prevention Information System, and HPV vaccination data were captured from the Zhejiang Municipal Immunization Information Management System. The incidence, temporal distributions and clinical symptoms of AEFI were analyzed.@*Results@#Totally 922 310 doses of HPV vaccines were immunized in Hangzhou City from 2017 to 2021, and 232 cases with AEFI were reported, with an overall incidence rate of 25.15/105 doses. The reported incidence rates of AEFI caused by HPV2, HPV4 and HPV9 vaccination were 31.13/105 doses, 25.93/105 doses and 22.01/105 doses, respectively. General reactions and abnormal reactions were predominant AEFI, and the reported incidence rates of general reactions and abnormal reactions were 21.58/105 doses and 2.60/105 dose, respectively. AEFI predominantly occurred 0 to 1 day post-immunization (165 cases, 71.12%), and the main clinical symptoms included local swelling of injection sites, hard tubercle and fever, with reported incidence rates of 10.30/105 doses, 5.96/105 doses and 6.18/105 doses, respectively. @*Conclusions@#Low incidence of AEFI was reported following HPV vaccination in Hangzhou City from 2017 to 2021, and all AEFI were mild. The safety of HPV2, HPV4 and HPV9 remains high.
