Objective To evaluate the long-term efficacy of transjugular intrahepatic portosystemic shunt(TIPS)with bare stents and Fluency covered stents in the treatment of portal hypertension,and to discuss its clinical value.Methods The clinical data of 29 patients with intractable ascites or esophagogastric fundus varices rupture and hemorrhage caused by cirrhotic portal hypertension,who received TIPS with bare stents and covered stents at the First Affiliated Hospital of Xinjiang Medical University of China(25 patients)and the Lishui Municipal Central Hospital of China(4 patients)between August 2012 and December 2017,were retrospectively analyzed.The patients were regularly followed up to check the survival status.The postoperative cumulative shunt patency rate and cumulative survival rate of the patients were analyzed by Kaplan-Meier method.Results The technical success rate of TIPS was 100％.The mean portal vein pressure was decreased from preoperative(40.21±3.24)cmH2O to postoperative(24.55±3.55)cmH2O(P＜0.05).The patients were followed up for 5.1-10.5 years.The postoperative 1-,3-,5-,7-year primary cumulative patency rates of the shunt were 89.7％,75.9％,75.9％ and 52.5％,respectively.The postoperative 5-,7-,9-and 10-year cumulative survival rates were 100％,66.9％,66.9％ and 33.4％,respectively.The incidence of hepatic encephalopathy was 13.8％(4/29).Conclusion Using bare stents combined with Fluency covered stents for TIPS is clinically safe and effective in the treatment of portal hypertension.This technique carries higher long-term shunt patency rate and low incidence of hepatic encephalopathy.Therefore,it can be used as a substitute for Viatorr stent when necessary.(J Intervent Radiol,2024,33:295-299)

Objective To evaluate the clinical application value of medical tissue glue in the treatment of acute hemoptysis by bronchial arterial embolization(BAE).Methods The clinical data of 78 patients who underwent emergency BAE for hemoptysis were retrospectively collected.Among them,18 patients who underwent embolization with medical tissue glue were selected as a study group,and other 18 patients who underwent embolization with absorbent gelatin sponge particles and spring coil were selected as a control group.The technical success rates,average surgical operation time,average surgical cost,postoperative hemoptysis recur-rence rate,and incidence of adverse reactions of the two groups were compared and analyzed.Results The technical success rates of the two groups were both 100％.There were no statistically significant differences in recurrence rate of postoperative hemoptysis and incidence of adverse reactions between the two groups(P＞0.05).The average surgical operation time of study group and control group were 53.4 min[(53.4±2.2)min]and 65.4 min[(65.4±2.8)min],and the average surgical cost were 3 651 yuan[(3 651±102.7)yuan]and 5 094 yuan[(5 094±136.3)yuan],respectively.Compared with the control group,the average surgical operation time and aver-age surgical cost of the study group were shorter,and the differences were statistically significant(P＜0.05).Conclusion Compared with absorbent gelatin sponge particles combined with spring coil embolization,the use of medical tissue glue for embolization is also safe and effective in the treatment of acute hemoptysis patients by BAE.The average surgical operation time is shorter,and the surgical cost for patients is lower.It is worth promoting in clinical practice.

Purpose: Mixed-lineage leukemia protein 4 (MLL4/KMT2D) is a histone methyltransferase, and its mutation has been reported to be associated with a poor prognosis in many cancers, including lung cancer. We investigated the function of MLL4 in lung carcinogenesis. Materials and Methods: RNA sequencing (RNA-seq) in A549 cells transfected with control siRNA or MLL4 siRNA was performed. Also, we used EdU incorporation assay, colony formation assays, growth curve analysis, transwell invasion assays, immunohistochemical staining, and in vivo bioluminescence assay to investigate the function of MLL4 in lung carcinogenesis. Results: We found that MLL4 expression was downregulated in non–small cell lung cancer (NSCLC) tissues compared to adjacent normal tissues and tended to decrease with disease stage progression. We analyzed the transcriptomes in control and MLL4- deficient cells using high-throughput RNA deep sequencing (RNA-seq) and identified a cohort of target genes, such as SOX2, ATF1, FOXP4, PIK3IP1, SIRT4, TENT5B, and LFNG, some of which are related to proliferation and metastasis. Our results showed that low expression of MLL4 promotes NSCLC cell proliferation and metastasis and is required for the maintenance of NSCLC stem cell properties. Conclusion Our findings identify an important role of MLL4 in lung carcinogenesis through transcriptional regulation of PIK3IP1, affecting the PI3K/AKT/SOX2 axis, and suggest that MLL4 could be a potential prognostic indicator and target for NSCLC therapy.

Objective:To investigate the clinical diagnostic value of MRI retention enema cannula enhanced scanning in the high complex anal fistula.Methods:The clinical data of 60 anal fistula patients underwent surgery treatment from May 2020 to May 2022 in Affiliated Hospital of Shanxi University of Traditional Chinese Medicine were retrospectively analyzed. All patients underwent MRI plain scanning and enhanced scanning before operation. Compared with the surgical results, the difference between MRI plain scanning and enhanced scanning in the diagnosis of high complex anal fistula was compared.Results:All of the 60 patients successfully completed surgical treatment, and 58 cases internal orifices, 55 cases complex anal fistulas and 53 cases high anal fistulas were found intraoperatively. MRI plain scanning results showed 32 cases internal orifices, 46 cases complex anal fistulas and 42 cases high anal fistulas were found. MRI enhanced scanning results showed 54 cases internal orifices, 53 cases complex anal fistulas and 50 cases high anal fistulas were found. Based on surgical results, the coincidence rates of internal orifice, complex anal fistula and high anal fistula in MRI enhanced scanning were significantly higher than those in MRI plain scanning: 93.10% (54/58) vs. 55.17% (32/58), 96.36% (53/55) vs. 83.64% (46/55) and 94.34% (50/53) vs. 79.25% (42/53), and there were statistical differences ( χ2 = 21.76, 4.95 and 5.27; P<0.01 or <0.05). Conclusions:The MRI retention enema cannula enhanced scanning has obvious advantages in the diagnosis of high complex anal fistula, which provides scientific reference value for the diagnosis and operation of high complex anal fistula in clinic.

Objective:To investigate the pathogen spectrum of acquired immunodeficiency syndrome (AIDS) patients with pulmonary opportunistic infections in the local area, and to evaluate the clinical application of metagenomic next-generation sequencing (mNGS) in these patients.Methods:From January to December 2021, AIDS patients with pulmonary infections admitted to Zhongnan Hospital of Wuhan University were enrolled. Their bronchoalveolar lavage fluid (BALF) was subjected to mNGS and coventional pathogen detection.Routine pathogen detection methods included smear, culture, polymerase chain reaction (PCR), and immunochromatographic colloidal gold. Fisher′s exact probability method was used for statistical analysis.Results:A total of 69 patients were included, and all of them were tested positive for mNGS. Among them, 53 cases (76.8%) were positive for fungi and viruses, 40 cases (58.0%) were positive for bacteria (excluding Mycobacterium tuberculosis (MTB) and nontuberculous mycobacteria (NTM)), six cases were positive for MTB, 11 cases were positive for NTM, and seven cases were positive for other pathogens. Mixed infections with two or more pathogens were found in 89.9%(62/69) of the patients. Among the conventional pathogen detections of BALF, 79.7%(55/69) of the patients were positive for pathogens, including 42 cases positive for Pneumocystis jirovecii PCR, 16 cases positive for BALF culture, nine cases positive for MTB PCR, and five cases positive for Cryptococcus antigen. The total detection rate of mNGS was 100.0%(69/69), which was higher than that of the conventional pathogen detection rate of 79.7%(55/69), and the difference was statistically significant (Fisher′s exact probability method, P<0.001). The specificity of mNGS detection was 88.4%. Combining clinical and two detection methods, the top five pathogens were Pneumocystis jirovecii (62.3%(43/69)), Candida (29.0%(20/69)), MTB (20.3%(14/69)), NTM and Talaromyces marneffei (15.9%(11/69), each). Fifty-three patients (76.8%) had co-infection with virus. Conclusions:The main cause of pulmonary infection in AIDS patients in this area is mixed infection, and Pneumocystis jirovecii is the most common pathogen. mNGS could significantly improve the pathogen detection rate in AIDS patients with pulmonary infections.

Objective:To determine S100A10 protein expression in psoriatic lesions, and to investigate its effect on psoriasis-like skin inflammation in imiquimod (IMQ) -induced mouse models.Methods:From January 2020 to June 2022, skin lesions were surgically collected from 28 patients with psoriasis in the Department of Dermatology, the First Affiliated Hospital of Xinxiang Medical University; normal skin tissues were collected from 18 healthy subjects in the Department of General Surgery and Department of Ophthalmology during the same period, and served as a control group. Immunohistochemical staining was performed to determine the S100A10 protein expression in skin lesions from psoriasis patients and normal skin tissues from healthy controls. Ten wild-type (WT) C57BL/6J female mice and 10 S100A10 -/- C57BL/6J female mice were selected to establish the IMQ-induced mouse models of psoriasis-like skin inflammation. Then, the mice were randomly divided into gene knock-out (KO) /IMQ group, WT/IMQ group, KO/vaseline (VAS) group, and WT/VAS group by using a random number table, and there were 5 mice in each group. The mice in the KO/IMQ group and WT/IMQ group were topically treated with IMQ cream (62.5 mg) on the shaved back daily to establish the mouse models of psoriasis-like skin inflammation, while the mice in the KO/VAS group and WT/VAS group were topically treated with vaseline cream (62.5 mg) daily, and both treatments lasted 7 consecutive days. Skin lesions on the back were observed daily. On day 7, the mice were sacrificed by cervical dislocation, and their dorsal skin tissues were excised. The IMQ-induced psoriasis-like skin inflammation was evaluated by the psoriasis area and severity index (PASI), pathological manifestations of skin lesions were observed by hematoxylin and eosin staining, the expression of S100A10 and Ki-67 in skin lesions was determined by immunohistochemical staining, the expression of STAT3, IL-17A and other cytokines was determined by Western blot analysis, and IL-17 mRNA expression was determined by real-time fluorescence-based quantitative PCR (qPCR). Statistical analysis was carried out by using the independent sample t-test, nonparametric U test, and chi-square test. Results:Immunohistochemical staining showed that the S100A10 protein expression was significantly lower in the psoriasis vulgaris lesions than in the normal control skin tissues ( Z = -3.47, P < 0.001). In the mouse models, the S100A10 protein expression was significantly lower in the skin lesions of mice in the WT/IMQ group than in the skin tissues of mice in the WT/VAS group ( t = 3.64, P = 0.007), and the Ki-67 expression was significantly higher in the KO/IMQ group than in the WT/IMQ group ( t = 2.97, P = 0.041). Additionally, the mice in the KO/IMQ group presented with more severe clinical manifestations such as scales and infiltration compared with those in the WT/IMQ group. Western blot analysis showed that the phosphorylated STAT3/STAT3 expression and IL-17A protein expression was significantly higher in the KO/IMQ group than in the WT/IMQ group ( t = 3.27, 3.48, P = 0.031, 0.025, respectively), and qPCR revealed that the IL-17A mRNA expression was also significantly higher in the KO/IMQ group than in the WT/IMQ group ( t = 2.73, P = 0.029) . Conclusion:S100A10 protein was underexpressed in the skin lesions of psoriasis patients, and the deletion of S100A10 protein aggravated IMQ-induced psoriasis-like skin inflammation in mice, possibly by upregulating STAT3 phosphorylation in the epidermis.

【Objective】 To compare the clinical efficacy of minimally invasive percutaneous approach with Wiltse approach in the treatment of thoracolumbar fracture without neurological deficit in young and middle-aged patients. 【Methods】 A prospective study was conducted in 108 patients with thoracolumbar fracture without neurological symptoms treated in Department of Orthopedics， The First Affiliated Hospital of Xi’an Jiaotong University from March 2015 to March 2018. We randomly assigned 54 patients to minimally invasive percutaneous approach group （Group A） and 54 ones to Wiltse approach group （Group B）. We compared the operation time， intraoperative blood loss， incision length， the number of intraoperative fluoroscopy times， and postoperative hospital stay of Group A and Group B. We also compared the VAS scores of the two groups before and 3 days after surgery and at each review， the vertebral frontal height compression ratio and Cobb Angle before and immediately after surgery， 3 months 1 year and 3 years after surgery， and ODI index before surgery and 3 months， 1 year and 3 years after surgery. 【Results】 All the 108 patients were followed up. There were no significant differences in operation time， intraoperative blood loss or postoperative hospital stay between the two groups （P>0.05）. The number of intraoperative fluoroscopy times was significantly smaller in Group B than in Group A （P<0.05）， and the incision length was shorter than that in Group A （P<0.05）. The two groups did not significantly differ in VAS score or ODI index before operation （P>0.05）， after operation， or at follow-up， while the anterior vertebral body height ratio and Cobb angle were significantly lower in Group B than in Group A （P<0.0125）. 【Conclusion】 Minimally invasive percutaneous approach and Wiltse approach are both safe and effective in the treatment of thoracolumbar fracture without neurological deficit. However， the number of intraoperative fluoroscopy times of Wiltse approach was significantly reduced， the incision length was smaller than that of the percutaneous pedicle group， and the postoperative anterior vertebral compression rate and Cobb Angle were lower than those of the percutaneous group， indicating better clinical efficacy.

Objective:To investigate the predictive value of dynamic platelet and hemagglutination-related parameters in patients with acute pancreatitis (AP).Methods:The patients admitted to the Department of Emergency Surgery in the First Affiliated Hospital of Zhengzhou University from January 2020 to December 2020 were analyzed. According to the inclusion criteria and exclusion criteria, patients with AP were retrospectively enrolled. According to the Chinese Guidelines for the Diagnosis and Treatment of Acute Pancreatitis (Shenyang, 2019), the patients were divided into two groups: severe acute pancreatitis (SAP group) and non-severe acute pancreatitis (non-SAP group) [including mild acute pancreatitis (MAP) and moderate severe acute pancreatitis (MSAP)]. A normal distribution of the maximum and mean aggregation rates of dynamic platelets (arachiidonic acid), plateletcrit (PCT) and bedside index for severity in acute pancreatitis (BISAP) scores and other measurement data were tested by t test, while measurement data of prothrombin time (PT), fibrinogen (FIB) and D-dimer that did not conform to normal distribution were tested by Mann-Whitney U test. χ 2 test was used for the counting data such as sex, age and etiology of patients in the two groups. The prognostic value of statistically significant indicators for non-SAP group and SAP group was further analyzed by receiver operating characteristic (ROC) curve. Results:A total of 146 patients with AP were enrolled, including 50 patients in SAP group and 96 in non-SAP group. The maximum and average aggregation rates of dynamic platelet (aracidonic acid) in the SAP group were (71.76±17.62) % and (67.91±18.10) %, PT (12.02±1.33) s, FIB (4.76±2.08) g/L, D-dimer (3.75±6.04) μg/L, PCT (0.23±0.08) %, and BISAP scores (1.42±1.18), which were all significantly higher than those in the non-SAP group [the maximum and average aggregation rates of dynamic platelet (arachiidonic acid) (46.65±20.11) % and (42.50±20.71) %, PT (11.50±1.51) s and FIB (3.91±1.48) g/L, D-dimer (1.00±1.37) μg/L, PCT (0.19±0.06) %, BISAP scores (0.45±0.66)] (all P<0.05). According to area under the ROC curve, the maximum and average aggregation rates of dynamic platelets (arachiidonic acid) in serum of patients with SAP were 0.83 and 0.82, respectively, and the sensitivities were 0.56 and 0.68, respectively. The specificity was 0.99 and 0.81, respectively, which was better than PT, FIB, D-dimer, PCT and BISAP scores in predicting the severity of AP. Conclusions:The maximum and average aggregation rates of dynamic platelets (arachidonic acid), PT, FIB, D-dimer, PCT and BISAP scores can be used as predictors of the severity of acute pancreatitis. The maximum and average aggregation rates of dynamic platelets (arachiidonic acid) were the best in predicting the severity of AP.

Objective:To investigate the efficacy and safety of programmed death-1 (PD1) inhibitor combined with transcatheter arterial chemoembolization (TACE) in the treatment of huge primary liver cancer.Methods:From June 2016 to December 2019, the clinical data of 31 patients with huge primary liver cancer enrolled in the Central Hospital of Lishui were retrospectively collected and analyzed. The tumor size ranged from 10.1 to 18.8 cm, with an average of (14.2±2.3) cm. The patients were divided into TACE group (TACE treatment, 18 cases) and combined group (one week after TACE, patients receiving a dose of 200 mg PD1 inhibitor administration every 21 days, 13 cases), according to whether patients receiving PD1 inhibitors. The patients were followed up. The disease control rate (DCR) were compared between the two groups using Mann-Whitney U test. The median overall survival (OS) and progression free survival (PFS) were calculated by Kaplan-Meier method. Results:The DCR in combined group (53.8%, 7/13) was higher than that in TACE group (22.2%, 4/18), and the difference was statistically significant ( Z=-2.13, P=0.04). The median PFS (5.0 months) in combined group was longer than that in TACE group (3.0 months), the difference was statistically significant (χ2=4.39, P=0.04). The median OS (15 months) in combined group was longer than that in control group (9 months), and the difference was statistically significant (χ2=5.51, P=0.02). Conclusion:The combine PD1 inhibitors with TACE is an effective and safe therapy for huge primary liver cancer.
