ABSTRACT
Objective:To study the clinical characteristics of congenital esophageal atresia (CEA) and risk factors of mortality associated with esophageal repair (ER) surgery.Methods:From January 2010 to December 2022, patients diagnosed of CEA using chest and abdomen X-ray and esophagography in our hospital were retrospectively reviewed. The patients were assigned into ER group and non-ER group according to the treatments. The ER group was subgrouped into survival group and death group according to the prognosis. Clinical data and outcomes were collected and compared between the groups.Results:A total of 553 cases were enrolled. According to Gross classification, 29 patients (5.2%) were type A, 2 patients (0.4%) were type B, 504 patients (91.1%) were type C, 6 patients (1.1%) were type D and 11 patients (2.0%) were type E. One patient had simple transluminal septal atresia of the esophagus. 406 patients were in ER group and 147 in non-ER group. Compared with ER group, non-ER group had significantly higher incidences of preterm birth, low birth weight and overall malformations (all P<0.05). In ER group, 152 patients (37.4%) received open thoracic surgery (OTS), 243 (59.9%) had video-assisted thoracoscopic surgery (VATS) and 11 (2.7%) were VATS converted to OTS. Postoperative anastomotic leakage (PAL) occurred in 92 patients (22.7%) and 15 patients (3.7%) died after surgery. The median length of hospital stay was 23 (17, 36) d. Compared with the survival group, the death group had higher incidences of preterm birth, low birth weight, VATS converted to OTS, mechanical ventilation after ER, and shorter length of hospital stay (all P<0.05). After adjusted for birth weight, VATS converted to OTS ( OR=9.585, 95% CI 1.899-48.374) and mechanical ventilation after ER ( OR=7.821, 95% CI 1.002-61.057) were risk factors of mortality in ER patients. Conclusions:Non-ER patients have higher incidences of preterm birth, low birth weight and overall malformations than ER patients. VATS is the method of choice for CEA. Preterm birth, low birth weight, VATS converted to OTS and mechanical ventilation after ER are risk factors of mortality in ER patients.

ABSTRACT
Objective To explore the risk factors for myocardial injury in esophagogastric variceal bleeding(EGVB)patients with liver cirrhosis during hospitalization.Methods A case-control trial was conducted on 235 EGVB patients admitted to our hospital between May 2021 and July 2022.Their basic information,laboratory results and relevant data during hospitalization were collected.According to their myocardial enzyme profiles during hospitalization,they were divided into myocardial injury group(n=46)and non-myocardial injury group(n=189).Univariate regression analysis and clinical correlation analysis were used to preliminarily screen the risk factors for myocardial injury secondary to EGVB caused by liver cirrhosis.Then,multivariate logistic regression analysis was used to further screen the risk factors.A nomogram was constructed based on the selected risk factors and the occurrence of myocardial injury.Receiver operating characteristic(ROC)curve was plotted to analyze the independent predictive value of these factors alone or combined together.Calibration curve analysis and internal verification were utilized to evaluate the predictive performance of the nomogram model.Subgroup verification was performed in the myocardial infarction group.Results Univariate analysis revealed that statistical differences were observed in age,sex,hypertension,renal disease,underlying diseases,vomiting,leukocytosis,increased alanine aminotransferase(ALT)or aspartate aminotransferase(AST),albumin,red blood cell hematocrit(HCT),international normalized ratio(INR),endoscopy within 6 h after admission,and Child-Pugh(CP)class between the myocardial injury group and the non-myocardial injury group(P＜0.01).Multivariate logistic regression analysis showed that age(P=0.014,OR=1.153,95％CI:1.030～1.291),underlying diseases(P=0.005,OR=1.122,95％CI:1.032～2.437),and albumin(P=0.012,OR=0.449,95％CI:0.241～0.837)were independent risk factors for inhospital myocardial injury in EGVB patients with liver cirrhosis.The AUC value of the above indicators combined together for predicting myocardial injury was 0.902.Hosmer-Lemeshow test and calibration curve analysis indicated that the nomogram had good prediction consistency(Chi-square=12.88,P=0.615).Internal verification correctly distinguished 86.4％of verification objects.Subgroup analysis of myocardial injury patients showed that albumin was also an independent risk factor for in-hospital myocardial injury in this population(AUC=0.80).Conclusion Age,underlying diseases,and albumin level are independent risk factors for in-hospital myocardial injury in EGVB patients with liver cirrhosis.Albumin level can be used as an independent risk factor for predicting myocardial infarction.Combination of the above 3 indicators has a high diagnostic value in early identification and prevention of myocardial injury in this patient population.
ABSTRACT
Objective To investigate whether Liuwei Dihuang Pills enhances the antigen cross-presenting ability of dendritic cell(DC)by increasing gap junctional intercellular communication(GJIC),and to explore the mechanisms involved.Methods Western Blot and immunofluorescence were used to observe the effects of Liuwei Dihuang Pills-containing serum on the expression and membrane localisation of gap junction protein connexin43(Cx43)in mouse melanoma cells(B16);Calcein-AM/DiI fluorescence tracer assay was used to observe the effects of Liuwei Dihuang Pills-containing serum on the function of GJIC in B16 cells;flow cytometry was used to observe the role of GJIC in the enhancement of DC antigen presenting ability by Liuwei Dihuang Pills-containing serum;and propidium iodide(PI)/Hoechst staining assay was used to observe the immunocidal effect of CD8+ T-lymphocytes.Results Western Blot and immunofluorescence experiments showed that Liuwei Dihuang Pills-containing serum led to the up-regulation of Cx43 expression;fluorescence tracer experiments proved that the GJIC function of B16 cells was significantly enhanced by Liuwei Dihuang Pills-containing serum;flow cytometry analyses showed that the DC antigen-presenting ability was enhanced by Liuwei Dihuang Pills-containing serum;and the results of PI/Hoechst staining showed that the immuno-killing effect of CD8+T-cells was more significant after the intervention of Liuwei Dihuang Pills-containing serum in B16-OVA.Conclusion Liuwei Dihuang Pills improve the GJIC function by up-regulating the Cx43 expression of melanoma cells,and then enhance the cross-presenting ability of DCs thus activating stronger CD8+ T-cell immunocidal responses.
ABSTRACT
Objective To observe the value of B1 corrected T1 mapping for distinguishing pathological types and differentiation degrees of lung cancers.Methods A total of 74 lesions in 65 patients with lung cancers were prospectively enrolled,including 49 poorly differentiated lesions and 25 moderately or well differentiated ones,i.e.42 adenocarcinomas,14 squamous cell carcinomas and 18 small cell lung cancers(all poorly differentiated).B1 corrected T1 mapping was performed,ROI(ROI1 and ROI2)were delineated using 2 methods,and T1 values of different pathological types and differentiation degrees lung cancers were compared.The receiver operating characteristic(ROC)curves were drawn,and the areas under the curve(AUC)were calculated.Results Significant differences of T1 values were found among different pathological types of lung cancer(all P＜0.05),as well as between small cell lung cancer and the rest 2 types of lung cancer(both P＜0.05).There were significant differences of T1 values between poorly differentiated and moderately well differentiated lung cancer(squamous cell carcinoma+adenocarcinoma)(both P＜0.05).Taken ROI1 T1 value=1 524.21 ms as the cut-off value,the AUC of T1 value for distinguishing poorly differentiated and moderately well differentiated lung cancer(squamous cell carcinoma+adenocarcinoma)was 0.698,with sensitivity of 64.50％and specificity of 76.00％.Taken ROI2 T1 value=1 630.68 ms as the cut-off value,the AUC of T1 value was 0.676,with sensitivity of 54.80％and specificity of 80.00％.Conclusion B1 corrected T1 mapping was helpful for distinguishing pathological types and differentiation degrees of lung cancers.
ABSTRACT
Objective:To understand the genome sequence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and spike protein variations during different epidemic periods in Wuxi City.Methods:Nucleic acid was extracted from the nasopharyngeal swab samples of six local cases of coronavirus disease 2019 (COVID-19) (from January to February, 2020) and 13 imported cases of COVID-19 (from March to September, 2021) in Wuxi City, and the whole genome was amplified to construct the sequencing library. The second-generation sequencer was used for sequencing. The CLC Genomics Workbench (21 version) software was used to analyze the offline data with NC_045512.2 as the reference strain, and MEGA 7.0 software was used to construct the phylogenetic tree.Identification of type was conducted by Nextstrain typing method and phylogenetic assignment of named global outbreak lineages (Pangolin) typing method.Results:There were five subtypes in Nextstrain and seven subtypes in Pangolin of the nineteen patients with COVID-19. Compared with NC_045512.2, the median nucleotide mutation sites were 29 (range 0 to 42) and amino acid mutation sites were 20 (range 0 to 34). The six local and 13 imported cases had no common nucleotide mutation sites and were in different evolutionary branches. The sequences of the six local cases were highly homologous with the reference strain sequences (NC_045512.2) at the early stage of the pandemic, and the evolutionary distance was close to that of the reference strain. The 13 imported cases were obviously divided into three evolutionary branches (Alpha, Beta, Delta variant).The four Beta variants shared eight amino acid mutation sites in spike protein, and the two Alpha variants shared eight amino acid mutation sites in spike protein, and the seven Delta variants shared five amino acid mutation sites in spike protein.Conclusions:New mutations of SARS-CoV-2 are constantly emerging during the epidemic. The increase of the nucleotide sites number may result in the change of spike protein amino acid. Therefore, the whole-genome sequencing analysis plays an important role in the accurate tracing of epidemic origin and adjustment of prevention and control measures.
ABSTRACT
Objective:To explore the independent risk factors of portal vein thrombosis (PVT) in liver cirrhosis, and to establish and evaluate a risk prediction model for PVT in patients with cirrhosis.Methods:A total of 295 cases of cirrhosis hospitalized in Renmin Hospital of Wuhan University from December 2019 to October 2021 were divided into a modeling set ( n=207) and an internal validation set ( n=88) by the random number table. In addition, patients with cirrhosis hospitalized in Yichang Central People's Hospital, Wuhan Puren Hospital, No.2 People's Hospital of Fuyang City and People's Hospital of China Three Gorges University during the same period were collected as an external validation set ( n=92). The modeling set was divided into PVT group ( n=56) and non-PVT group ( n=151). Univariate analysis was used to preliminarily screen the related indicators of PVT, and then multivariate logistic regression analysis with forward stepwise regression was used to determine independent risk factors for PVT. A nomogram prediction model was constructed based on the independent risk factors obtained. The internal and external validation set were used to verify the predictive ability of the model. Distinction degree was used to evaluate the ability of the model to distinguish patients with or without PVT. Hosmer-Lemeshow goodness-of-fit test was used to evaluate the consistency between predicted risk and the actual risk of the model. Results:Univariate analysis showed that smoking, history of splenectomy, trans-jugular intrahepatic portosystemic shunt (TIPS), gastrointestinal bleeding and endoscopic variceal treatment, and levels of hemoglobin, alanine aminotransferase, aspartate aminotransferase and D-dimer were significantly different between the PVT group and the non-PVT group ( P<0.05). Multivariate logistic regression analysis found that smoking ( P=0.020, OR=31.21, 95% CI: 1.71-569.40), levels of D-dimer ( P=0.003, OR=1.12, 95% CI: 1.04-1.20) and hemoglobin ( P=0.039, OR=0.99, 95% CI: 0.97-1.00), history of TIPS ( P=0.011, OR=18.04, 95% CI: 1.92-169.90) and endoscopic variceal treatment ( P=0.001, OR=3.21, 95% CI: 1.59-6.50) were independent risk factors for PVT in patients with liver cirrhosis. Receiver operator characteristic (ROC) curve analysis showed that the area under the ROC curve (AUC) for the internal validation set was 0.802 (95% CI: 0.709-0.895) ( P<0.001), and the AUC for the external validation set was 0.811 (95% CI: 0.722-0.900) ( P<0.001). Both AUC were larger than 0.75. The calibration curve of Hosmer-Lemeshow goodness-of-fit test showed that the P values of both internal validation set ( χ2=3.602, P=0.891) and the external validation set ( χ2=11.025, P=0.200) were larger than 0.05. Conclusion:Smoking, history of TIPS or endoscopic variceal treatment, levels of D-dimer and hemoglobin are independent risk factors for PVT in patients with liver cirrhosis. The prediction nomogram model based on the above factors has strong predictive ability.
ABSTRACT
BACKGROUND@#Polycystic ovary syndrome (PCOS) is the primary cause of anovulatory infertility, bringing serious harm to women's physical and mental health. Acupuncture may be an effective treatment for PCOS. However, systematic reviews (SRs) on the efficacy and safety of acupuncture for PCOS have reported inconsistent results, and the quality of these studies has not been adequately assessed.@*OBJECTIVE@#To summarize and evaluate the current evidence on the efficacy and safety of acupuncture for PCOS, as well as to assess the quality and risks of bias of the available SRs.@*SEARCH STRATEGY@#Nine electronic databases (Cochrane Library, MEDLINE, Embase, PsycINFO, CINAHL, Chinese National Knowledge Infrastructure, Wanfang Data, Chongqing VIP Chinese Science and Technology Periodical Database, and China Biology Medicine disc) were searched from their establishment to July 27, 2022. Based on the principle of combining subject words with text words, the search strategy was constructed around search terms for "acupuncture," "polycystic ovary syndrome," and "systematic review."@*INCLUSION CRITERIA@#SRs of randomized controlled trials that explored the efficacy and (or) safety of acupuncture for treating patients with PCOS were included.@*DATA EXTRACTION AND ANALYSIS@#Two authors independently extracted study data according to a predesigned form. Tools for evaluating the methodological quality, risk of bias, reporting quality, and confidence in study outcomes, including A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR 2), Risk of Bias in Systematic Reviews (ROBIS), Preferred Reporting Items for Systematic Reviews and Meta-analyses for Acupuncture (PRISMA-A), and the Grading of Recommendations Assessment, Development and Evaluation (GRADE), were used to score the included SRs.@*RESULTS@#A total of 885 studies were retrieved, and 11 eligible SRs were finally included in this review. The methodological quality of 2 SRs (18.18%) was low, while the other 9 SRs (81.82%) were scored as extremely low. Four SRs (36.36%) were considered to be of low risk of bias. As for reporting quality, the reporting completeness of 9 SRs (81.82%) was more than 70%. Concerning the confidence in study results, 2 study results were considered to have a high quality of evidence (3.13%), 14 (21.88%) a "moderate" quality, 28 (43.75%) a "low" quality, and 20 (31.24%) considered a "very low" quality. Descriptive analyses suggested that combining acupuncture with other medicines can effectively improve the clinical pregnancy rate (CPR) and ovulation rate, and reduce luteinizing hormone/follicle-stimulating hormone ratio, homeostasis model assessment of insulin resistance, and body mass index (BMI). When compared with medicine alone, acupuncture alone also can improve CPR. Further, when compared with no intervention, acupuncture had a better effect in promoting the recovery of menstrual cycle and reducing BMI. Acupuncture was reported to cause no adverse events or some adverse events without serious harm.@*CONCLUSION@#The efficacy and safety of acupuncture for PCOS remains uncertain due to the limitations and inconsistencies of current evidence. More high-quality studies are needed to support the use of acupuncture in PCOS.

OBJECTIVE@#To observe the effects of the Xingnao Kaiqiao (regaining consciousness and opening orifices) acupuncture on hemorrhagic transformation and limb motor function after intravenous thrombolysis with recombinant tissue plasminogen activator (rt-PA) in stroke patients.@*METHODS@#A total of 130 stroke patients after rt-PA thrombolytic were divided into an acupuncture group (58 cases, 1 case dropped off) and a non-acupuncture group (72 cases, 7 cases dropped off) according to whether they received acupuncture treatment. Propensity score matching (PSM) was used to match each group, with 38 patients in each group. The patients in the non-acupuncture group received rt-PA thrombolytic therapy and western medical basic treatment. In addition to the basic treatment, the patients in the acupuncture group received Xingnao Kaiqiao acupuncture at Shuigou (GV 26), bilateral Neiguan (PC 6), and ipsilateral Sanyinjiao (SP 6), Chize (LU 5), once a day for 14 days. The incidence of hemorrhagic transformation within 30 days after onset was compared between the two groups. The Fugl-Meyer assessment (FMA) score and activities of daily living (ADL) score were observed at baseline and 30 days, 6 months, 1 year after onset in the two groups. The disability rate at 6 months and 1 year after onset was recorded, and safety was evaluated in both groups.@*RESULTS@#The incidence of hemorrhagic transformation in the acupuncture group was 5.3% (2/38), which was lower than 21.1% (8/38) in the non-acupuncture group (P<0.05). At 30 days, 6 month, and 1 year after onset, the FMA and ADL scores of both groups were higher than those at baseline (P<0.01), and the scores in the acupuncture group were higher than those in the non-acupuncture group (P<0.01). The disability rate in the acupuncture group at 1 year after onset was 10.5% (4/38), which was lower than 28.9% (11/38) in the non-acupuncture group (P<0.05). There was no significant difference in the incidence of adverse events between the two groups (P>0.05).@*CONCLUSION@#The Xingnao Kaiqiao acupuncture method could reduce the incidence of hemorrhagic transformation in stroke patients after intravenous thrombolysis with rt-PA, improve their motor function and daily living ability, and reduce the long-term disability rate.

Objective:To analyze the changes of gray matter volume and resting-state functional connectivity in children with attention deficit hyperactivity disorder (ADHD) comorbid with oppositional defiant disorder (ODD).Methods:A total of 22 ADHD comorbid with ODD children (ADHD-ODD group, n=22) were selected from a public-assess resting-state fMRI ADHD cohort, namely, ADHD-200.Meanwhile, 22 age- and sex- matched ADHD children without ODD (ADHD group, n=22) and 22 healthy children(control group, n=22) were also included.T1-weighted MRI and resting-state fMRI scans were performed on all of the participants.The voxel-based morphometric (VBM) method was used to compare the volume of gray matter in three groups.The gray matter with aberrant volume was set as the region of interest(ROI) for mapping the functional connectivity of the whole brain.For comparison of gray matter volumes, one-way ANOVA and two-sample t-test analysis were applied, while two-sample t-test analysis was used for comparison of functional connectivity. Results:Compared with the control group, ADHD-ODD group showed decreased gray matter volume in the left cerebellum anterior lobe (MNI coordinate: x, y, z=-19.5, -42, -18) and right cerebellum anterior lobe (MNI coordinate: x, y, z=19.5, -39, -21). The left cerebellum anterior lobe showed increased functional connectivity with left superior frontal gyrus, left middle frontal gyrus (MNI coordinate: x, y, z=-24, 19, 43), right superior frontal gyrus, right middle frontal gyrus (MNI coordinate: x, y, z=30, 9, 45) and bilateral precuneus, posterior cingulate gyrus(MNI coordinate: x, y, z=-6, -35, 24). Compared with the ADHD group, ADHD-ODD group showed decreased gray matter volume in the right cerebellum anterior lobe (MNI coordinate: x, y, z=19.5, -37.5, -22.5). The right cerebellum anterior lobe showed increased functional connectivity with bilateral superior frontal gyrus, bilateral middle frontal gyrus, bilateral medial frontal gyrus, anterior cingulate gyrus and posterior cingulate gyrus(MNI coordinate: x, y, z=18, -12, 42), bilateral cuneus, bilateral lingual gyrus(MNI coordinate: x, y, z=9, -87, 27).Conclusion:ADHD comorbid with ODD children show decreased cerebellum volume and excessive functional connectivity with several brain regions of the cerebral hemispheres, which may be one of the neuropathological bases of cognitive, emotional, and behavioral disorders.
ABSTRACT
Objective:To evaluate the efficacy and safety of endoscopic ultrasound (EUS)-guided coil embolization combined with endoscopic cyanoacrylate injection for gastric fundal varices with large spontaneous shunt.Methods:Data of 24 patients with gastric fundal varices with large spontaneous shunt (the smallest diameter was 5-15 mm) treated by EUS-guided coil embolization combined with endoscopic cyanoacrylate injection in Renmin Hospital of Wuhan University from December 2016 to December 2020 were retrospectively analyzed. The short-term efficacy (the rates of technical success, five-day rebleeding and six-week mortality) and long-term efficacy (the rates of one-year rebleeding, one-year mortality and three-year mortality) and safety (ectopic embolism) were evaluated.Results:The technical success rate was 91.7% (22/24), and the five-day rebleeding rate was 0 (0/22). Computed tomography angiography of portal vein reexamined 2 days after the treatment showed embolism of splenic vein in 1 patient (4.5%). The median follow-up time was 14.9 months (ranging 1.0-48.6 months) and 2 patients were lost during follow-up. The six-week mortality was 0 (0/20), and the one-year rebleeding rate was 35.0% (7/20). Among 12 patients who underwent endoscopy in the follow-up, 5 had aggravation of esophageal varices, and 5 had aggravation of portal hypertension gastropathy. The one-year and three-year mortalities were 5.0% (1/20) and 20.0% (4/20), respectively, neither of which was related to such events as bleeding or ectopic embolism.Conclusion:EUS-guided coil embolization combined with endoscopic cyanoacrylate injection for gastric fundal varices with large spontaneous shunt is effective and safe in short term, with a low rate of ectopic embolism. Long-term efficacy and safety need to be further confirmed.
ABSTRACT
Objective:To investigate the efficacy and safety of different endoscopic treatment strategies for grade Ⅰ-Ⅲ internal hemorrhoids.Methods:Clinical data of 107 internal hemorrhoid patients who received endoscopic sclerotherapy or band ligation in Renmin Hospital of Wuhan University from December 2018 to December 2020 were retrospectively studied. Postoperative adverse events, efficacy, and satisfaction were followed up.Results:Among the 107 patients, there were 45 patients (42.06%) with grade Ⅰ, 55 (52.34%) with grade Ⅱ, and 6 (5.60%) with grade Ⅲ. At the same time, 94.39% (101/107) patients underwent other gastrointestinal endoscopic treatment. The postoperative follow-up time ranged from 3 to 25 months, with a median of 5 months. A total of 84 patients underwent routine endoscopic injection sclerotherapy, and 8 had adverse events after the surgery. The overall effective rate was 97.61% (82/84), and satisfaction rate was 95.24% (80/84). Nine underwent endoscopic foam sclerotherapy, and no postoperative adverse events were observed. The overall effective rate and the satisfaction rate were both 100.00% (9/9). Among the 11 patients undergoing endoscopic band ligation, 2 had adverse events after the surgery. The overall effective rate was 81.82% (9/11), and the satisfaction rate was 72.73% (8/11). Three patients underwent sclerotherapy combined with ligation, and 2 had postoperative adverse events. The overall effective rate was 100.00% (3/3), and the satisfaction rate was 66.67% (2/3). Sclerotherapy was generally superior to ligation in operation cost. Further subgroup analysis for grade Ⅰ-Ⅱ patients showed that for grade Ⅰ patients, sclerotherapy was better than band ligation in the incidence of postoperative pain ( P<0.05), and for grade Ⅱ patients, no statistically significant differences were observed in adverse events, effective rate and satisfaction rate ( P>0.05). Conclusion:Both endoscopic injection sclerotherapy and band ligation for internal hemorrhoids are safe and effective, and may not increase the risk of adverse events when simultaneously completed with other gastrointestinal endoscopic treatment.

ABSTRACT
BACKGROUND@#High-frequency irreversible electroporation (H-FIRE) is a novel, next-generation nanoknife technology with the advantage of relieving irreversible electroporation (IRE)-induced muscle contractions. However, the difference between IRE and H-FIRE with distinct ablation parameters was not clearly defined. This study aimed to compare the efficacy of the two treatments in vivo.@*METHODS@#Ten Bama miniature swine were divided into two group: five in the 1-day group and five in the 7-day group. The efficacy of IRE and H-FIRE ablation was compared by volume transfer constant (Krans), rate constant (Kep) and extravascular extracellular volume fraction (Ve) value of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI), size of the ablation zone, and histologic analysis. Each animal underwent the IRE and H-FIRE. Temperatures of the electrodes were measured during ablation. DCE-MRI images were obtained 1, 4, and 7 days after ablation in the 7-day group. All animals in the two groups were euthanized 1 day or 7 days after ablation, and subsequently, IRE and H-FIRE treated liver tissues were collected for histological examination. Student's t test or Mann-Whitney U test was applied for comparing any two groups. One-way analysis of variance (ANOVA) test and Welch's ANOVA test followed by Holm-Sidak's multiple comparisons test, one-way ANOVA with repeated measures followed by Bonferroni test, or Kruskal-Wallis H test followed by Dunn's multiple comparison test was used for multiple group comparisons and post hoc analyses. Pearson correlation coefficient test was conducted to analyze the relationship between two variables.@*RESULTS@#Higher Ve was seen in IRE zone than in H-FIRE zone (0.14 ± 0.02 vs. 0.08 ± 0.05, t = 2.408, P = 0.043) on day 4, but no significant difference was seen in Ktrans or Kep between IRE and H-FIRE zones at all time points (all P > 0.05). For IRE zone, the greatest Ktrans was seen on day 7, which was significantly higher than that on day 1 (P = 0.033). The ablation zone size of H-FIRE was significantly larger than IRE 1 day (4.74 ± 0.88 cm2vs. 3.20 ± 0.77 cm2, t = 3.241, P = 0.009) and 4 days (2.22 ± 0.83 cm2vs. 1.30 ± 0.50 cm2, t = 2.343, P = 0.041) after treatment. Apoptotic index (0.05 ± 0.02 vs. 0.73 ± 0.06 vs. 0.68 ± 0.07, F = 241.300, P 0.05). Electrode temperature variations were not significantly different between the two zones (18.00 ± 3.77°C vs. 16.20 ± 7.45°C, t = 0.682, P = 0.504). The Ktrans value (r = 0.940, P = 0.017) and the Kep value (r = 0.895, P = 0.040) of the H-FIRE zone were positively correlated with the number of hepatocytes in the ablation zone.@*CONCLUSIONS@#H-FIRE showed a comparable ablation effect to IRE. DCE-MRI has the potential to monitor the changes of H-FIRE ablation zone.

In the present study, the composition and content of pulmonary surfactant (PS) were analyzed to explore the hypoxia adaptation mechanism in plateau zokors (Myospalax baileyi) and plateau pikas (Ochotona curzoniae). 36 plateau zokors and plateau pikas were trapped alive at the Laji Mountain in Guide County, Qinghai Province (at the altitude of about 3 600 m), and 36 Sprague-Dawley (SD) rats were purchased from the experimental animal center of Lanzhou University (at the altitude of about 1 500 m). All animals were lavaged after laboratory anesthesia, the blood in lung tissues was fully washed out and the lung tissues were then taken out to obtain the bronchoalveolar lavage fluid by bronchoalveolar lavage. The composition and content of phospholipids in the PS of three different kinds of animals were analyzed by using high performance liquid chromatography; the protein composition, content and types in the PS were analyzed by G-250 Coomassie brilliant blue method, polyacrylamide gel electrophoresis (PAGE) and mass spectrometry; the dissolved oxygen in the PS solutions were determined by using dissolved oxygen electrode. The results showed that the total contents of phospholipids in the PS were successively increased among plateau zokors, plateau pikas and SD rats (P 0.05). The relative content of PSe had no significant differences between plateau zokors and plateau pikas (P > 0.05), but both were significantly higher than that of SD rats (P < 0.01). The serum albumin (SA) was identified in the PS of three kinds of animals, including homologous tetramer protein containing heme, which is composed of hemoglobin β subunit, in plateau zokors and plateau pikas. Immunoglobulin (Ig) heavy chain was found in PS of plateau zokors and SD rats. The content of Ig heavy chain in plateau zokor was significantly higher than that in SD rats (P < 0.01), and the content of protein containing heme was significantly higher than that in plateau pikas (P < 0.05). The amount of dissolved oxygen was successively decreased in the PS among plateau zokors, plateau pikas and SD rats (P < 0.01), but it was significantly higher than that in saline (P < 0.01). These results suggest that the total content of proteins in the PS of plateau zokors and plateau pikas was significantly higher, while the total content of phospholipids was significantly decreased. There were high content of homologous tetramer protein containing heme in the PS of plateau zokors and plateau pikas. The relative content of DPPC, the main component of phospholipids, was significantly increased in plateau zokors. The changes of PS component and content improve the adaptability of the two plateau animals in hypoxia environment.

Objective:To investigate the optimal emergency endoscopy timing in patients with esophagogastric variceal bleeding (EGVB).Methods:The clinical data of patients with EGVB emergency endoscopy in Renmin Hospital of Wuhan University from December 2018 to November 2020 were collected and analyzed. According to the time interval from admission to the start of emergency endoscopy, they were divided into emergency endoscopy group (<6 h, n=115) and early endoscopy group (6-24 h, n=57). The baseline data, clinical efficacy and postoperative situation of the two groups were compared, and the risk factors of 6-week mortality of EGVB emergency endoscopy were analyzed by univariate and multivariate analysis. Results:In terms of baseline characteristics, there were no significant differences in age, gender, causes, shock index, model for end-stage liver disease (MELD) score, charlson complication index (CCI) score, portal hypertension related complications between the two groups ( P<0.05). However, the albumin (ALB) in emergency endoscopy group was significantly lower than that in early endoscopy group ( P<0.001). There were significant differences in Child Pugh grading and Child Pugh score between the two groups ( P=0.002, P=0.001). In terms of endoscopic efficacy, the detection rate of bleeding site in emergency endoscopy group was significantly higher than that in early endoscopy group (90.4% and 73.7%, P<0.05). There was no significant difference in operation duration, immediate hemostasis success rate, 5-day rebleeding rate, rescue treatment demand and 6-week mortality between the two groups ( P>0.05). There was no significant difference in bleeding related death between the two groups ( P>0.05). In addition, there was no significant difference in blood product consumption, intensive care unit (ICU) stay and total hospital stay between the two groups ( P>0.05). Multivariate analysis showed that Child Pugh grade C ( P=0.018), MELD score ( P=0.005) and CCI score ( P=0.001) were independent risk factors for 6-week death outcome of EGVB patients, while emergency endoscopic intervention time was not related to 6-week death outcome ( P=0.5). Conclusions:The efficacy of early endoscopic intervention is no worse than that of emergency endoscopic intervention, except for the identification of bleeding site. Child-Pugh grade C, MELD score, and CCI score are the independent risk factors for 6-week mortality, while the timing of emergency endoscopy is not associate with 6-week mortality in EGVB patients.
ABSTRACT
Objective:To evaluate the efficacy and safety of lactulose combined with polyethylene glycol for bowel preparation before colonoscopy in patients of different risks.Methods:A total of 208 patients undergoing colonoscopy were enrolled, including 108 high-risk and 100 low-risk patients. The high-risk patients were divided into group A (54 taking lactulose + polyethylene glycol) and group B (54 taking polyethylene glycol), and the low-risk patients were divided into group C (49 taking lactulose + polyethylene glycol) and group D (51 taking polyethylene glycol). The Boston bowel preparation score, cecal intubation time, withdrawal time, the detection rate of colonic polyps and adenoma, and the incidence of adverse reactions were observed.Results:Among the high-risk patients, the Boston bowel preparation score and adenoma detection rate in group A [(6.35±1.15) scores, 46.3%] were significantly higher than those in group B [(5.76±0.89) scores, 22.2%, both P<0.05], and the first defecation interval in group A was significantly shorter than that in group B [(1.20±0.85) h VS (3.29 ± 2.93) h, P<0.05]. There was no significant difference in adequate bowel preparation rate, polyp detection rate, frequency of defecation or incidence of adverse reactions between group A and B. In the low-risk patients, the first defecation interval in group C was significantly shorter than that in group D [(1.65 ± 1.35) h VS (3.42 ± 2.64) h, P<0.05], and the incidence of adverse reactions was significantly lower than that in group D (44.9% VS 64.7%, P<0.05). There was no significant difference in adequate bowel preparation rate, Boston bowel preparation score, adenoma detection rate, polyp detection rate or frequency of defecation between group C and D. Conclusion:For the high-risk patients, the effect of lactulose combined with polyethylene glycol for bowel cleansing is better than that of traditional polyethylene glycol in the improvement of the Boston bowel preparation score, adenoma detection rate, and the first defecation interval. For low-risk patients, lactulose combined with polyethylene glycol regimen has few advantages over traditional polyethylene glycol regimen.
ABSTRACT
Aim To investigated the effect of p-CA on depression-like behaviors of mice of olfactory bulbectomy and its possible mechanism. Methods The olfactory bulbectomy (OBX) model of mice was established by an operation of olfactory bulbectomy. The behaviors of the mice were detected by the forced swimming test and the tail suspension test. Results The depression-like behavior in the forced swimming and tail suspension test and the in the open field test significantly increased in OBX mice; however, p-CA improved the depres- sion-like behavior in the forced swimming and tail sus pension test and the hyper-locomotor activity in open field test in OBX mice. Moreover, treatment with AMPA receptor antagonist NBQX blocked this improving effect of p-CA. While, treatment with AMPA receptor agonist CX546 enhanced this improving effect of p-CA. Conclusions P-CA improves depression-like behaviors of OBX mice, and AMPA receptors may mediate this effect.
