Objective:To investigate the effect of modified percutaneous closure in the treatment of ventricular septal rupture.Methods:This study is a retrospective cohort study. Forty-four patients with ventricular septal rupture who underwent percutaneous closure at the Fuwai Central China Cardiovascular Hospital from December 2017 to October 2023 were included. According to the closure method, patients were divided into the modified group (11 cases) and the traditional group (33 cases). Surgical success was defined as successful placement of the occluder. The operation time, X-ray intake, sheath bending rate, incidence of ventricular fibrillation and pericardial tamponade, and postoperative residual shunt were compared between the two groups.Results:The age of the patients was (75.0±5.7) years, with 20 (45%) males. There were 3 cases of operation failure in the traditional group, while all patients in the modified group were successfully occluded. The procedure time in the modified group was shorter than that in the traditional group (40 (35, 45) min vs. 60 (50, 65)min, P<0.001); X-ray dose intake was lower ((442.43±73.26)mGy vs. (784.45±247.78)mGy, P<0.001). There was no occurrence of sheath bending in the modified group, while the incidence of sheath bending in the traditional surgery group was 46% (15/33), and the difference was statistically significant ( P=0.017). Intraoperative ventricular fibrillation and pericardial tamponade occurred in 7 cases (21%) and 2 cases (6%) in the traditional group respectively, while none occurred in the modified group, but the differences between the groups were not statistically significant (both P>0.05). There was no significant difference in residual shunt between the two groups (3.6 (2.5, 4.3) mm vs. 4.0 (3.5, 4.5) mm, P=0.506). Conclusion:The procedure of modified ventricular septal rupture closure is more simplified, with a lower incidence ofventricular fibrillation and pericardial tamponade.

Severe acute pancreatitis (SAP) is a serious disease commonly encountered in the emergency department and can precipitate systemic inflammatory response syndrome and multiple organ dysfunction syndrome with high morbidity and mortality. However, its etiology and pathogenesis are complex and have not been fully elucidated. Clinical studies can provide some data on the etiology, pathophysiology, and outcome associated with the disease. However, research on SAP cannot be carried out in humans directly for ethical considerations. It is very important to establish an appropriate animal model of SAP to elucidate its pathogenesis and seek innovative therapeutic methods. In this paper, we reviewed the latest research progress at home and abroad in animal models of SAP over the past several years.

Objective To analyze the diversity and composition changes of gut fungal communities between mouse model of total parental nutrition(TPN)and normal control mice.Methods After mouse model of TPN was constructed,fresh feces were collected from TPN mice(n=5)and normal control mice(n=5).Internal transcribed spacer(ITS)DNA sequencing was applied to determine intestinal fungi,and then bioinformatics analysis was conducted to identify the differences in fungal diversity,structure,and functional properties between the 2 groups of mice.Results There were significant differences in Alpha diversity(P＜0.05)and Beta diversity(P＜0.01)of intestinal fungi between the 2 groups.In the TPN model group,the relative abundances of Candida,Penicillium,Aspergillus and Talaromyces were obviously reduced(all P＜0.01).LEfSe analysis indicated that the above 4 strains were notably enriched in the normal control mice.Conclusion TPN mice exhibit characteristic changes in the composition of gut fungal flora compared to normal control mice.Dysfunction of gut fungal community may promote the occurrence of TPN related complications,and regulating the balance of gut fungal community may become a new strategy for preventing TPN related complications.

Objective:To investigate the causal correlation between depression and stress urinary incontinence(SUI)using Mendelian randomization(MR)analysis.Methods:We searched the FinnGen Consortium database for genome-wide association studies(GWAS)on depression and obtained 23 424 case samples and 192 220 control samples,with the GWAS data on SUI provided by the UK Biobank,including 4 340 case samples and 458 670 control samples.We investigated the correlation between depression and SUI based on the depression data collected from the Psychiatric Genomics Consortium(PGC).We employed inverse-variance weighting as the main method for the MR study,and performed sensitivity analysis to verify the accuracy and stability of the findings.Results:Analysis of the data from the UK Biobank and FinnGen Consortium showed that depression was significantly correlated with an increased risk of SUI(P=0.005),but not SUI with the risk of depression(P=0.927).And analysis of the PGC data verified the correlation of depression with the increased risk of SUI(P=0.043).Conclusion:Depression is associated with an increased risk of SUI,while SUI does not increase the risk of depression.

ObjectiveTo reveal the differences of the related pathogenicity gene mutations between sebaceous adenocarcinoma （SC） of scalp and sebaceous adenoma （SA） of scalp on whole exome level. MethodsWhole exome sequencing was performed on a SC sample and a SA sample by Illumina Hiseq 2500 platform. Suspicious single nucleotide variation sites were selected for mutation conservation and functional analysis. SciClone was used to track subclone evolution and clonal map information was obtained for each tumor sample. The high-frequency significant gene mutations in the tumor sample were screened by MutSigCV software， and compared with the known driver genes. ResultsTwo driver genes TFDP1 and ACVR1B harboring mutations in scalp SC compared to SA were found. ConclusionsThe finding of mutation in driver genes TFDP1 and ACVR1B should be confirmed in a large cohort， which might reveal the mechanism of scalp SC development and find a therapeutic target for SC.

Objective: To evaluate the efficacy of neoadjuvant chemotherapy (NACT) in the treatment of locally advanced olfactory neuroblastoma (ONB), and to explore the factors related to the efficacy of NACT. Methods: A total of 25 patients with ONB who underwent NACT in Beijing TongRen Hospital from April 2017 to July 2022 were retrospectively analyzed. There were 16 males and 9 females, with an average age of 44.9 years (ranged 26-72 years). There were 22 cases of Kadish stage C and 3 cases of stage D. After multiple disciplinary team(MDT) discussion, all patients were treated sequentially with NACT-surgery-radiotherapy. Among them, 17 cases were treated with taxol, cis-platinum and etoposide (TEP), 4 cases with taxol, nedaplatin and ifosfamide (TPI), 3 cases with TP, while 1 case with EP. SPSS 25.0 software was used for statistical analysis, and survival analyses were calculated based on the Kaplan-Meier method. Results: The overall response rate of NACT was 32% (8/25). Subsequently, 21 patients underwent extended endoscopic surgery and 4 patients underwent combined cranial-nasal approach. Three patients with stage D disease underwent cervical lymph node dissection. All patients received postoperative radiotherapy. The mean follow-up time was 44.2 months (ranged 6-67 months). The 5-year overall survival rate was 100.0%, and the 5-year disease-free survival rates was 94.4%. Before NACT, Ki-67 index was 60% (50%, 90%), while Ki-67 index was 20% (3%, 30%) after chemotherapy [M (Q₁, Q₃)]. The change of Ki-67 before and after NACT was statistically significant (Z=-24.24, P<0.05). The effects of age, gender, history of surgery, Hyams grade, Ki-67 index and chemotherapy regimen to NACT were analyzed. Ki-67 index≥25% and high Hyams grade were related to the efficacy of NACT (all P<0.05). Conclusions: NACT could reduce Ki-67 index in ONBs. High Ki-67 index and Hyams grade are clinical indicators sensitive to the efficacy of NACT. NACT-surgery-radiotherapy is effective for patients with locally advanced ONB.

ObjectiveTo understand the physical development level of 3-7 years old children in Zhag′yab， and to provide reference for local health decision-making. MethodsA cross-sectional study was conducted between June 2021 and July 2021， with a sample of 1 247 Tibetan children aged 3-7 years from kindergartens in 13 districts of Zhag′yab. Their height and weight were measured and the hemoglobin was detected by a unified method. Standard statistical method was adopted （Z-score method）. Z-scores of length /height-for-age （HAZ）， Z-scores of weight-for-age （WAZ）， Z-scores of body mass index （BMI）-for-age （BAZ） and Z-scores of weight-for-height （WHZ） were calculated by WHO Anthro v3.2.2 and WHO Anthro Plus. The nutritional status of children was evaluated according to WHO diagnostic criteria for malnutrition and anemia. ResultsThe average WAZ and HAZ of children aged 3 to 7 in Zhag′yab were lower than the WHO standards，except for the WAZ of 4-year old， the differences were statistically significant （P<0.05）. The overall detection rate of malnutrition was 25.7%， stunting， underweight， wasting， overweight， obesity and anemia were 11.6%， 11.8%， 10.8%， 3.3%， 1.8% and 29.3%， respectively. The detection rates of all indicators in boys were higher than those in girls， and the differences were not statistically significant （P>0.05）. The overweight rate and obesity rate of rural children were lower than those of urban children， and the other detection rates were higher than those of urban children. The differences of underweight rate， obesity rate and anemia rate were statistically significant between urban and rural children （P<0.05）. Among the detection rates of all indicators in different age groups， there were statistically significant differences in the overweight rate and the anemia rate （P<0.05）. The overweight rate of children aged 4 and the anemia rate of children aged 5 were the highest. ConclusionsThe physical development of children aged 3 to 7 in Zhag′yab is poor， and the prevalence of malnutrition and anemia is high. Underweight and anemia are more serious in rural children， and the overweight and obesity problem of urban children is emerging. More attention should be paid to promote their nutritional status. The prevention and intervention of children’s malnutrition should be strengthened in Zhag′yab.

The trauma to primary tooth may lead to developmental disturbances of permanent tooth. Because the traumatic events are often forgotten as accurred earlier, the timely diagnosis and intervention treatment are not conducted, resulting in aesthetic and functional disorders. This paper systematically elaborates the types of developmental disturbances in permanent tooth after traumatic injuries to the primary predecessor, and the etiology, mechanism, related factors as well as the treatment options, in order to provide references for the prevention of serious complications in inherited permanent tooth caused by primary tooth trauma.

ObjectiveTo study the possible correlation between serum osteoprotegerin （OPG）/soluble receptor activator of the nuclear factor κB ligand （sRANKL） levels and the left ventricular diastolic dysfunction （LADD） in patients with type 2 diabetes mellitus （T2DM）. MethodsTotally 68 T2DM patients and 37 healthy controls were selected. Serum OPG and sRANKL were determined by solid-phase enzyme-linked immunosorbent assay （ELISA）. The left ventricular diastolic function of T2DM patients was measured by transthoracic echocardiography， where E/A < 1 were regarded as LVDD. T2DM patients were further divided into two subgroups according to E/A ratio （E/A≥1.0 and E/A<1）. Spearman correlation analysis， logistic regression and ROC curves were used to assess the possible correlation between serum OPG/sRANKL and LADD in T2DM patients. ResultsCompared with the healthy controls， serum OPG level in T2DM patients was higher with statistically significant difference （P <0.01）， while serum sRANKL level was lower without statistically significant difference （P =0.32）. T2DM patients with E/A<1 had significantly higher OPG level and lower sRANKL level than those with E/A≥1（P <0.01） in subgroup analysis. Spearman correlation analysis showed serum OPG level was negatively correlated with E/A ratio， while sRANKL was positively related with E/A ratio. In single factor logistic regression analyses， serum OPG ［OR （95% CI）=1.068 （1.031， 1.106）， P<0.001］ and sRANKL ［OR （95% CI）=0.976 （0.959， 0.992）， P=0.003］ were significant correlation with LVDD in T2DM patients. ROC curve analysis showed that the sensitivity and specificity of combined OPG and sRANKL in diagnosing T2DM patients LADD were 78.13% and 88.3%， respectively （area under the curve： 0.857； 95% CI=（0.768， 0.946）； P<0.001）. ConclusionsThe elevated OPG and decreased sRANKL levels may be associated with LADD in T2DM patients.

Objective: To investigate the application value of computed tomography (CT) examination of lymph node short diameter in evaluating cardia-left gastric lymph node metastasis in thoracic esophageal squamous cell carcinoma (ESCC). Methods: A total of 477 patients with primary thoracic ESCC who underwent surgical treatment in the Affiliated Cancer Hospital of Zhengzhou University from January 2013 to December 2017 were collected. All of them underwent McKeown esophagectomy plus complete two-field or three-field lymph node dissection. Picture archiving and communication system were used to measure the largest cardia-left gastric lymph node short diameter in preoperative CT images. The postoperative pathological diagnosis results of cardia-left gastric lymph node were used as the gold standard. Receiver operating characteristic (ROC) curve was used to evaluate the efficacy of CT lymph node short diameter in detecting the metastasis of cardia-left gastric lymph node in thoracic ESCC, and determine the optimal cut-off value. Results: The median short diameter of the largest cardia-left gastric lymph node was 4.1 mm in 477 patients, and the largest cardia-left gastric lymph node short diameter was less than 3 mm in 155 cases (32.5%). Sixty-eight patients had cardia-left gastric lymph node metastases, of which 38 had paracardial node metastases and 41 had left gastric node metastases. The lymph node ratios of paracardial node and left gastric node were 4.0% (60/1 511) and 3.3% (62/1 887), respectively. ROC curve analysis showed that the area under the curve of CT lymph node short diameter for evaluating cardia-left gastric lymph node metastasis was 0.941 (95% CI: 0.904-0.977; P<0.05). The optimal cut-off value of CT examination of the cardia-left gastric lymph node short diameter was 6 mm, and the corresponding sensitivity, specificity and accuracy were 85.3%, 91.7%, and 90.8%, respectively. Conclusion: CT examination of lymph node short diameter can be a good evaluation of cardia-left gastric lymph node metastasis in thoracic ESCC, and the optimal cut-off value is 6 mm.
