Visualization of Risk Factors and Predictive Models for Early Death of Neonatal Gastric Perforation.

A retrospective analysis was performed from May 2003 to October 2021 at our hospital. One hundred and eleven neonates diagnosed with gastric perforation were categorized into non-survivor and survivor groups based on prognosis. The mortality rate was 23.42%. Logistic regression was used to analyze the factors influencing the early neonatal death. The non-survivor groups showed more abdominal distension, vomiting, hypoxia, acidosis, hyperkalemia, and coagulation abnormalities. Serum potassium concentration (odds ratio [OR] 2.148, P = .043) was an independent risk factor; however, arterial partial pressure of oxygen (OR 0.977, P = .024), bicarbonate (OR 0.779, P = .023), and platelet count (OR 0.986, P = .014) had protective effects on neonatal death. Based on this, a visualized nomogram prediction model was constructed, patients who had a nomogram score of more than 163.787 was considered to have high risks of mortality, the area under the curve of this was up to 0.828 (95% confidence interval [0.733, 0.923]), the sensitivity was 80.0%, and the specificity was 76.9%.

Objective:To evaluate the curative effect, safety and feasibility of percutaneous transhepatic cholangio drainage(PTCD) combined with balloon dilatation in treating benign biliary-enteric anastomosis stricture(BBES).Methods:The clinical data of 33 patients with benign biliary-enteric anastomosis stricture, who were admitted to the First Affiliated Hospital of Zhengzhou University during the period from January 2013 to May 2019, were retrospectively analyzed. There were 23 cases of benign etiology and 10 cases of malignant etiology, benign strictures of which 15 cases were located in the hepatic hilum and of which 18 cases outside of it. All patients were considered as benign stenosis by at least two imaging examinations of magnetic resonance imaging of pancreatic or enhanced MRI or enhanced CT, laboratory examinations of tumor markers and other clinical data before operation. 10 cases of malignant etiology were confirmed by intraoperative biopsy and pathology. All patients were treated with balloon dilatation at an interval of 1 to 4 weeks after PTCD. The changes of clinical symptoms, bilirubin and liver function before and after operation were compared and analyzed, and the postoperative complications and anastomotic patency rate were followed up.Results:PTCD combined with balloon dilatation was performed successfully in all patients, and the success rate was 100%. After operation, the benign biliary-enteric anastomosis stricture was significantly improved in all patients, and the clinical symptoms were improved obviously. The liver function and bilirubin decreased significantly in all patients after operation, and there was significant statistical significance ( P<0.05). There is no serious complications such as biliary bleeding and biliary fistula were found after operation. At 3 months, 6 months, 12 months, 24 months and 36 months after operation, the anastomotic patency rates of all patients were 90.9%(30/33), 72.7%(24/33), 63.6%(21/33), 63.6%(21/33), 60.6%(20/33), respectively. During the whole follow-up period, anastomotic restenosis happened in 13 patients, of which 9 cases with restenosis, the benign stenosis site of the anastomosis was the hepatic hilum and of which 4 cases located on the outside of the hepatic hilum.

Expression and significance of the ABAT gene in hepatocellular carcinoma: An analysis based on data mining / 临床肝胆病杂志

ObjectiveTo investigate the expression and significance of the ABAT gene in hepatocellular carcinoma (HCC) using related databases. MethodsThe Oncomine database and GEPIA were used to analyze the expression of ABAT in HCC tissue. GEPIA was used to investigate the correlation of ABAT mRNA with the survival time and pathological stage of HCC patients. The MethHC database was used to analyze the methylation level of ABAT promoter region. The String database was used to analyze the network of proteins interacting with ABAT protein. The Human Protein Atlas was used to analyze the expression of ABAT protein in HCC tissue and the influence of the protein expression of ABAT on prognosis. ResultsThe mRNA expression of ABAT in HCC tissue was significantly lower than that in normal liver tissue; patients with lower mRNA expression tended to have a poorer prognosis (log-rank, P=0.002 1) and a higher degree of malignancy (P=0.002 34). The protein expression of ABAT in HCC tissue was significantly lower than that in normal liver tissue, and patients with lower protein expression tended to have a poorer prognosis (log-rank, P=2.14×10-3). The methylation level of ABAT promoter region in HCC tissue was significantly higher than that in normal liver tissue (P＜0.005). The proteins interacting with ABAT included ALDH1A3, ALDH9A1, ALDH3A2, GAD1, and GAD2, which might be involved in cell functions such as cell apoptosis, redox, and neurotransmitter secretion. ConclusionData mining of tumor gene databases shows that there are low levels of mRNA and protein expression of ABAT in HCC tissue, which is associated with patient’s survival time. At present, database mining can provide a reference for the diagnosis and prognosis evaluation of HCC and a theoretical basis for tumor research in the future.

Objective To study pharmacokinetics and tissue distribution of CalliSpheres Beads (CB) loaded Arsenic trioxide (ATO) on rabbit VX2 liver tumor by transcatheter arterial chemoembolization (TACE). Method Sixty four rabbits with VX2 liver tumors were randomly divided into 4 groups: control group, CB group, CBATO group and cTACE group. Blood samples were taken at specific time points after TACE.The blood concentration of ATO,liver and kidney functions were examined respectively. In each group, every 4 rabbits were sacrificed on 1 days,3 days,7 days and 14 days after operation. The tumor,liver,kidney, lung,heart and muscle were taken to detect the drug concentration. Bilateral t?test was used to compare the drug concentration in blood and tissue between CBATO group and cTACE group. Results Statistically,The levels of ALT and AST in group CBATO and cTACE on 1st,3rd and 7th days after TACE were significantly higher than those in CB group(ALT: F=25.872, 17.69, 7.016, AST: F=46.365, 32.385, 12.548, P<0.05) respectively. The ALT and AST levels in CBATO group were statistically lower than those in cTACE group (ALT: t=0.369, 0.432, 0.169, 0.353, AST: t=0.488, 0.593, P>0.05). There were no statistically significant differences in the levels of BUN and Scr between the four experimental groups at each observation time point. Statistically, 10 minutes and 20 minutes after TACE, the blood drug concentration inCBATO was significantly lower than that in cTACE (t=7.675, 6.461, P<0.001). while 12 hours after operation,blood drug concentration in CBATO group was higher than that in cTACE group. In tumor tissue,the concentration of ATO in CBATO was higher than that in cTACE,and there was no statistical differences on the 1st day after TACE(t=2.155, P=0.068), but there was a statistical differences between 3rd, 7th and 14th days (t=11.462, 7.624, 2.649, P<0.05). Conclusion CBATO could prolong the time of drug metabolism,increase the drug concentration in tumor tissue,and didn′t aggravate the damage of liver and kidney function.

In all 13 patients, no severe complications such as hepatic failure, renal insufficiency, bone marrow suppression, liver abscess, bile leakage complicated by infection and gastrointestinal bleeding occurred. Conclusion For the treatment of BCLC stage B HCC, TACE by using CBATO is safe and effective with reliable short-term effect.

Endovascular interventional therapy for Cockett syndrome associated with deep vein thrombosis of left lower extremity / 介入放射学杂志

Objective To evaluate the clinical effect of endovascular interventional therapy in treating Cockett syndrome associated with deep vein thrombosis (DVT) of left lower extremity.Methods The clinical data of a total of 256 patients with Cockett syndrome complicated by DVT of left lower extremity,who were admitted to authors' hospital during the period from January 2011 to January 2015,were retrospectively analyzed.The patients were treated with catheter-directed thrombolysis,balloon dilatation of the occluded or narrowed venous segment,and/or stent implantation.The circumference differences of the affected limbs before and after treatment and the long-term patency rates were compared.Results Of the 256 patients with Cockett syndrome complicated by DVT of left lower extremity,complete dissolution of thrombus was achieved in 232 (90.6％) and partial dissolution of thrombus in 24 (9.4％).The circumference difference of thigh and calf was (7.12±2.15) and (4.57±2.81) cm respectively before and after treatment.Iliac vein reconstruction was carried out in 206 patients,among them simple balloon dilatation was employed in 46 and balloon dilatation together with stent implantation was adopted in 160.The patients were followed up for 9-24 months with a mean of 15 months.In simple balloon dilatation group,3 patients lost touch with the authors during the following-up period,26 patients (60.5％) developed iliac vein occlusion and post-embolization syndrome occurred in 21 patients (48.8％).In balloon dilatation plus stent implantation group,11 patients lost touch with the authors during the following-up period,stenosis or occlusion of the stent was seen in 13 patients (8.7％),post-embolization syndrome was observed in 15 patients (10.1％).The differences in vascular stenosis or occlusion and in the occurrence of post-embolization syndrome between the two groups were statistically significant (P＜0.001).Conclusion For the treatment of Cockett syndrome complicated by DVT of left lower extremity,catheter-directed thrombolysis and balloon dilatation combined with stent implantation carry definite clinical curative effect.

Association between SERPINH1 gene expression level in gastric cancer tissue with pathology and prognosis / 国际检验医学杂志

Objective To investigate the association between SERPINH1 gene expression in gastric cancer tissue with the pathology and prognosis and its action mechanism in gastric cancer.Methods The gastric cancer data in the TCGA and GEO public databases were collected,and the retrospective analysis and survival analysis were conducted on the SERPINH1 expression data of the tumor tissue samples and related clinical information;the gene set enrichment analysis(GSEA) was used to analyze the SERPINH1 expression related functional gene sets and to investigate the SERPINH1 action mechanism.Results In 421 cases of gastric cancer sample,the SERPINH1 expression level had no significant differences with the tumor grade,N stage and metastasis.However,its high expression was significantly correlated with the tumor invasion depth(T stage)(P=0.049).The higher the expression level,the preater the invasion depth.In the survival analysis,the patients with high SERPINH1 expression showed a poorer prognosis than those with low SERPINH1 expression[P<0.001,HR(95%CI):1.97 (1.61-2.41)].The gene set enrichment analaysis found that the related gene sets such as tumor signal pathway and tumor microenvironment were enriched in the SERPINH1 high expression samples.The gene expression chip data in 69 cases of gastric cancer and paracancerous tissue also suggested that SERPINH1 was highly expressed in gastric cancer (P<0.000 1) with a greater diagnostic value (AUC=0.988 1).Conclusion High expression of SERPINH1 is correlated with the occurrence and development of gastric cancer,and has a greater clinical significance.

Clinical efficacy of the combination of transjugular intrahepatic portosystemic shunt and catheter-directed thrombolysis in the treatment of acute portal vein thrombosis accompanied by Budd-Chiari syndrome with extensive occlusion of hepatic veins / 中华消化杂志

Objective To evaluate the clinical efficacy of combination of transjugular intrahepatic portosystemic shunt (TIPS) and catheter-directed thrombolysis (CDT) in the treatment of acute portal vein thrombosis (PVT) accompanied by Budd-Chiari syndrome (BCS) with extensive occlusion of the hepatic veins.Methods From March 2013 to December 2015,nine patients of acute PVT accompanied by BCS with extensive occlusion of the hepatic veins were collected,and the patients were treated by the combination of TIPS and CDT.The clinical symptoms,liver function and portal vein hemodynamics of patients were observed.After operation,portal vein and shunt patency was followed up by Doppler ultrasound.The patients were followed up seven days,one,three,six months,and every six months after the operation.Paired sample t test was performed for statistically analysis.Results The study enrolled nine patients,six male and three female,with an average age of (41.6 ± 10.9) years old.Operation was successfully performed in eight patients,and of whom three were completed under the assist of perctaneous transhepatic approach.After operation,the blood flow of portal vein was unobstructed and clinical symptoms of portal vein hypertension were obviously improved.There was no significant difference in portal vein diameter between pre-operation ((13.6 ± 2.1) cm) and seven days ((12.5±1.7) cm),one month ((12.1±2.9) cm),three months ((12.9±3.2) cm),six months ((11.6± 1.8) cm) after operation (all P＞0.05).And the portal vein velocity after operation were (79.3± 14.6),(84.4±17.3),(87.3±21.4) and (80.1±12.6) cm/s,respectively,which were higher than that before operation ((9.8 ± 3.1) cm/s),and the differences were statistically significant (t=28.169,34.713,36.519,30.314,all P＜0.01).The maximum cross sectional area ratios of the thrombus to the lumen after operation were (17.1±6.9)％,(19.1±6.2)％,(16.2±±5.5)％ and (16.7±5.1)％,respectively,which were lower than that before operation ((78.2 ±14.5)％),and the differences were statistically significant (t=26.182,23.931,29.371,27.471,all P＜0.01).At the seventh day after operation,the pressure of portal vein decreased from (42.2±8.9) cmH2O (1 cmH2O=0.098 kPa) to (19.6±4.2) cmH2O (t=17.410,P＜0.01).At seven days,one month,three months and six months after operation,albumin levels ((30.7±3.9),(30.9±4.2),(29.9±3.1) and (33.1±4.7) g/L) were all higher than that before operation ((26.5 ± 4.8) g/L),and the differences were statistically significant (t =4.785,4.874,2.874,5.402,all P＜0.05).The levels of transaminase after operation (32.9±21.6),(39.5±22.4),(24.8± 19.8),(37.1±26.9) U/L) were all lower than that before operation ((99.6±31.7) U/L),and the differences were statistically significant (t=27.624,24.913,33.671 and 25.019,all P＜0.01).During eight to 17 months follow-up,TIPS stent shunt stenosis was found in one case at three months after operation and the blood flow recovered after treatment of balloon dilation.The shunt and blood flow of portal vein of the other seven cases were clear.None of the eight patients had the symptoms of hepatic encephalopathy and pulmonary embolism.Operation was not successfully performed in one case,and 29 days later the patient died of hepatic and renal failure.Conclusion The combination of TIPS and CDT is safe and effective in the treatment of acute PVT accompanied by BCS with extensive occlusion of the hepatic veins,which maintain the blood flow of portal vein clear during short-and medium-term follow-up.

Correlation of arterial total compliance and carotid-femoral pulse wave velocity: an echocardiographic study / 中华医学超声杂志（电子版）

Objective To explore the correlation between arterial total compliance indices, stroke volume/pulse pressure (SV/PP), SV adjusted by body surface area/PP (SV′/PP) and carotid-femoral pulse wave velocity (PWV), and investigate the value of SV/PP, SV′/PP in the evaluation of clinical arterial stiffness (AS). Methods Forty-five hospitalized patients with coronary heart disease (CHD) in Tangdu Hospital of Fourth Military Medical University from March to December 2016 were included in this study (CHD group). Forty-five healthy volunteers who took a health checkup in Tangdu Hospital at the same period were also included as healthy controls. SV was measured by echocardiography, and the PP was calculated through traditional blood pressure measurement. Body surface area was calculated by Du Bois formula. Carotid-femoral PWV was measured by Doppler ultrasonography. Unpaired t test was used to compare the AS indices between CHD group and healthy controls. Spearman correlation analysis was used to evaluate the correlation between SV/PP, SV′/PP and carotid-femoral PWV.Results SV/PP, SV′/PP were decreased [(1.23±0.26) ml/mmHg vs(1.37±0.27) ml/mmHg, (0.66±0.13) ml/m2?mmHg vs(0.74±0.15) ml/m2?mmHg, 1 mmHg=0.133 kPa], carotid-femoral PWV was increased [(9.49±2.05) m/s vs(8.16±1.07) m/s] in CHD patients when compared with control group with statistical significance (t=2.0971,P<0.05;t=2.1643,P<0.05;t=2.8321,P<0.01, respectively). Both SV/PP and SV′/PP in healthy controls and CHD group inversely correlated with the corresponding Carotid-femoral PWV (healthy controls:r=-0.64,-0.56, bothP<0.001; CHD group:r=-0.53, P=0.0002,r=0.61,P<0.001). While SV′/PP showed a stronger correlation with carotid-femoral PWV. Conclusions Arterial total compliance decreases and AS increases in CHD patients compared with healthy controls. SV/PP, derived from echocardiography and blood pressure measurement, correlates with carotid-femoral PWV, the″golden standard″ index of AS. After adjusted by body surface area, SV′/PP correlates more strongly with carotid-femoral PWV. SV/PP and SV′/PP are expected to provide a simple and convenient way for clinical noninvasive AS evaluation.

Performance of a new suspended filler biofilter for removal of nitrogen oxides under thermophilic conditions and microbial community analysis.

A suspended biofilter, as a new bioreactor, was constructed for the removal of nitrogen oxides (NOX) from simulated flue gas under thermophilic conditions. The suspended biofilter could be quickly started up by inoculating the thermophilic denitrifying bacterium Chelatococcus daeguensis TAD1. The NO concentration in the inlet stream ranged from 200mg/m(3) to 2000mg/m(3) during the operation, and inlet loading ranged from 8.2-164g/(m(3)·h). The whole operation period was divided into four phases according to the EBRT. The EBRT of phases I, II, III and IV were 88s (9-43d), 44s (44-61d), 66s (62-79d) and 132s (80-97d), respectively. An average NO removal efficiency of 90% was achieved during the whole operation period, and the elimination capacity increased linearly with the increase in NO inlet loading and the maximum elimination capacity reached 146.9g/(m(3)·h). No clogging was observed, although there was a high biomass concentration in the biofilter bed. The remarkable performance in terms of NO removal could be attributed to the rich bacterial communities. The microbial community structure in the biofilm was investigated by high throughput sequencing analysis (16S rRNA MiSeq sequencing). The experimental results showed that the microbial community structure of the biofilm was very rich in diversity, with the most abundant bacterial class of the Alphaproteobacteria, which accounted for 36.5% of the total bacteria, followed by Gammaproteobacteria (30.7%) and Clostridia (27.5%). It was worthwhile to mention that the dominant species in the suspended biofilter biofilm were all common denitrifying bacteria including Rhizobiales (inoculated microbe), Rhodospirillales, Enterobacteriales and Pseudomonadales, which accounted for 19.4%, 17%, 21.6% and 7%, respectively. The inoculated strain TAD1 belonged to Alphaproteobacteria class. Because high-throughput 16S rRNA gene paired-end sequencing has improved resolution of bacterial community analysis, 16S rRNA gene sequencing of these bacteria could provide more functional and phylogenetic information about the bacterial communities.
