AIM:To investigate the effect of plasmin on epithelial sodium channel γ-subunit(γ-ENaC)acti-vation in mouse M-1 cells and the role of nuclear factor-κB(NF-κB).METHODS:Mouse M-1 cells were divided into three experimental parts.In the first part,the cells were divided into a control group,a plasmin group,and a plasmin+BAY 11-7082(NF-κB inhibitor)group to explore the effects of plasmin on inflammatory factors and γ-ENaC.In the sec-ond part,the cells were divided into a control group,a BAY 11-7082 group and a BAY 11-7082+plasmin group.M-1 cells were pretreated with BAY 11-7082 to explore the role of NF-κB in the regulation of γ-ENaC expression by plasmin.In the third part,the cells were divided into a control group,a plasmin group and an interleukin-6(IL-6)group.M-1 cells were treated with plasmin or IL-6 to explore the regulatory effect of IL-6 downstream of NF-κB on γ-ENaC.After drug interven-tion,the levels of IL-6,tumor necrosis factor-α(TNF-α),monocyte chemoattractant protein-1(MCP-1)and IL-1β in cell culture supernatants were detected by ELISA.The protein levels of phosphorylated inhibitor of nuclear factor-κB α(p-IκBα)/IκBα,p-NF-κB p65/NF-κB p65,and γ-ENaC was detected by Western blot.The distribution of γ-ENaC on the membrane was detected by immunofluorescence staining.RESULTS:Compared with control group,the levels of IL-6,TNF-α,MCP-1 and IL-1β in the supernatants of cells treated with 10 mg/L plasmin for 24 h were increased(n=3,P<0.01),the protein levels of p-IκBα/IκBα,p-NF-κB p65/NF-κB p65 and γ-ENaC were increased(n=5,P<0.01),and the distribution of γ-ENaC on the membrane was increased.Compared with plasmin group,the levels of IL-6,TNF-α,MCP-1,IL-1β,p-IκBα/IκBα,p-NF-κB p65/NF-κB p65 and γ-ENaC,and the γ-ENaC distribution on the membrane were lowered in plasmin and BAY 11-7082 coculture group(n=3,P<0.05 or P<0.01).Compared with control group,the ratio of p-NF-κB p65/NF-κB p65 decreased in BAY 11-7082 group(n=5,P<0.05),whereas there was no significant change in γ-ENaC.After stimulation with plasmin,the levels of p-IκBα/IκBα,p-NF-κB p65/NF-κB p65 and γ-ENaC in-creased(n=5,P<0.05 or P<0.01),and the γ-ENaC distribution on the membrane increased.Treatment with IL-6,downstream of NF-κB,increased the protein expression of γ-ENaC(n=5,P<0.05)and the distribution of γ-ENaC on the membrane after 24 h of intervention.CONCLUSION:The regulation of γ-ENaC expression by plasmin in mouse M-1 cells is related to the abnormal increase in inflammatory factors after NF-κB activation.

Objective:To examine the effectiveness of thin struct bare stents for the treatment of spontaneous isolated dissection of the superior mesenteric artery (SIDSMA).Methods:The data of 32 patients admitted to First Hospital of Jiaxing (20 cases) and Jinling Hospital (12 cases) with SIDSMA from January 2016 to January 2021 were retrospectively analyzed. There were 27 males and 5 females, aging (54.8±9.4) years (range: 36 to 75 years). All patients were treated with thin struct bare stents. Controllable spring coils were used to fulfill the false lumen in 2 cases. Symptoms, vascular remodeling pattern at the SIDSMA lesion, and patency of the stents were observed during follow-up.Results:The surgical success rate was 100%. According to the length of the lesions and stents, the number of stents implanted was 1 in 17 cases, 2 in 11 cases and 3 in 4 cases. The angiography showed that blood flow in the stent was smooth. The numerical rating scale for abdominal pain decreased from 6.1±1.5 (range: 4 to 10) preoperatively to 1.0 (1.0) (range: 0 to 3) 1 hour postoperatively ( W=528, P<0.01). The compression rate of the true lumen of the superior mesenteric artery decreased from (92.3±6.7)% (range: 25% to 94%) preoperatively to 0.8 (1.2)% (range: 0 to 3.2%) 1 month postoperatively ( W=528, P<0.01). The primary patency rate of CT angiography at 1 month postoperatively was 100%. The vascular remodeling rate was (92.3±6.7)% (range: 80% to 100%). All patients were followed for (46.3±17.0) months (range: 24 to 76 months). The cumulative patency rates in 1, 2 and 5 years were all 100%. Conclusion:The use of thin struct bare stents for SIDSMA could obtained the expected safety and efficacy.

Objective: Based on observational, longitudinal and intervention study of common diseases among students in Jiangsu Province, this paper presents the current progress of two year follow up of myopia cohort regarding the association between growth parameters with progression of myopia among children and adolescents in areas with rapid economic growth. Methods: This survey adopted the stratified cluster sampling method for school selection. The full automatic computer optometry (TOPCON RM800) was used to track myopia related parameters for all participants from 2019 to 2020 under the condition of mydriasis (compound topicamide eye drops). Relationship between growth parameters of children and adolescents and the incidence and progression of myopia was analyzed by using Cox regression multiple statistical model. Results: The myopia rates of students from grade 1 to grade 3 in 2019 were 5.4%, 21.5% and 37.3% respectively. After one year, the myopia rates of all school stages increased to 25.3%, 43.3% and 58.1% respectively( χ 2=53.59, 49.63, 32.52, P <0.01). The mean diopter of right eye and left eye after mydriasis were ( 0.30± 1.24/0.39±1.26)D in 2019 and (-0.33±1.54/-0.19±1.55)D in 2020, respectively based on Cox multiple regression results, age ( HR =1.21, 95% CI =1.09-1.34), naked eye vision ( HR =0.08, 95% CI =0.07-0.11), height ( HR =0.98, 95% CI =0.97-0.99) showed a strong correlation with the incidence and progression of myopia( P <0.05). Conclusion Myopia is growing rapidly in the central region of Jiangsu Province. It is suggested that diopter, axial length, naked eye vision, age, height and other indicators should be included in the refractive archives of children and adolescents in the region.

This study evaluates the immediate effects of the endocardial electrical defibrillation delivered by two transvenous defibrillation systems on left ventricular (LV) function in the animal model. Automatic cardiac defibrillation systems with bipolar leads (group I) and tripolar leads (group II) were placed in the hearts of 10 dogs (group I) and 10 pigs (group II),respectively. Transesophageal echocardiography with two dimensional image, M-mode and pulse Doppler were performed at baseline and after several episodes of defibrillation (DF). Each animal in group 1 underwent 4 DF with 64 Joules; the animals in group2 underwent an average of 8 DF with a total of 210 Joules. LV fractional area contraction, isovolumic relaxation time, and both ratios of velocities and time-velocity integrals in transmitral Doppler flow E and A waves exhibited no significant change after the shocks. This study suggests that the repeated low-energy electrical countershocks delivered by two transvenous defibrillation systems do ndt cause LV global systolic and/or diastolic dysfunction.

OBJECTIVETo retrospectively compare combined endovascular intervension with traditional bypass operation for the treatment of Budd-Chiari syndrome (BCS).

METHODSFrom July 1989 to June 2001, 49 patients undergoing surgery for BCS were studied. 32 operations were performed by traditional bypass (from superior mesenteric vein or inferior vena cava to right auricle), and 17 by combined endovascular operation.

RESULTSThe data demonstrated a high incidence of perioperative complications, longer hospital stay, and expensive cost in the former group than in the latter group (P < 0.01). The mid-term effects were significantly better in the latter than in the former (P < 0.05). Severe complications occurred in the bypass group included hepatoencephalopathy, obtinacy ascites, cardiac dysfunction, and embolization of vascular grafts.

CONCLUSIONSCombined endovascular intervention and shunting are the treatment of choice for BCS, with different combination according to its clinical type. This approach is simple, safe, effective, and economic.
