Objective To investigate the effects of different extracorporeal membrane oxygenation(ECMO)bypass modes on the prognosis of patients with combined pulmonary fibrosis and emphysema(CPFE)during lung transplantation.Methods A retrospective analysis was conducted on 44 CPFE patients who underwent lung transplantation,and they were divided into the venous-venous ECMO(VV-ECMO)group(30 cases)and the venous-arterial ECMO(VA-ECMO)group(14 cases).The preoperative,intraoperative,postoperative and follow-up related indicators of two groups were compared.Results Compared with the VV-ECMO group,the patients in the VA-ECMO group were younger,had higher pulmonary artery pressure before surgery,fewer posterolateral incision types,longer operation times,and higher incidence of postoperative bronchopleural fistula(all P<0.05).The pulmonary artery pressure decreased after surgery in both groups,with a greater decrease in the VA-ECMO group(P<0.05).There was no statistically significant difference in postoperative survival rates between the two groups(P>0.05).Conclusions Both VA-ECMO and VV-ECMO are safe and effective in lung transplant patients with CPFE.The bypass mode has no significant impact on the short and medium-term prognosis of the patients.VA-ECMO is more suitable for patients with higher preoperative pulmonary artery pressure.

Diabetes mellitus(DM)stands as a chronic metabolic ailment predominantly characterized by elevated blood glucose lev-els,stemming from either a resistance to insulin or aberrations in insulin secretion.The ensuing persistent hyperglycemia,a direct con-sequence of pancreatic β-cell devastation,acts as a catalyst for a myriad of complications,inclusive of extensive neuropathies.The dis-ease has substantial prevalence and mortality rates,underscoring the gravity of its impact on public health.Dental pulp stem cells(DPSCs)are readily obtainable,and they exhibit a profound capacity for self-renewal,multi-lineage differentiation,and vigorous pro-liferation.Remarkably,DPSCs can differentiate into pancreatic β-cells,subsequently participate in insulin secretion and play a pivotal role in immune modulation.This has achieved notable advancements in the therapeutic domain,particularly in the treatment of chronic diseases.Furthermore,DPSCs harbor the potential to mitigate symptoms in patients afflicted with type 1 diabetes.They navigate this therapeutic pathway through mechanisms that involve suppressing autoimmunity,modulating inflammatory responses,and counteracting oxidative stress.This article meticulously reviews the biological characteristics inherent to DPSCs and explores their multifaceted thera-peutic potential in addressing DM and its associated complications.Through this endeavor,the article aims to contribute to the refine-ment and enhancement of DM management strategies.

Objective:To analyze the clinical characteristics of patients with spontaneous splenorenal shunt (SSRS) in liver cirrhosis, and to compare the effects and prognosis of different treatments.Methods:The data of cirrhotic patients with SSRS at the First Affiliated Hospital of Zhengzhou University between 2016-2022 were retrospectively analyzed.Patients were divided into Group A receiving conservative treatment, Group B by simple embolization, Group C undergoing TIPS combined with embolization, and Group D given liver transplantation. Life status, liver function changes, incidences of adverse events, and survival between groups were compared.Results:SSRS diameter was positively correlated with blood ammonia ( R=0.478) and negatively correlated with portal vein diameter ( R=-0.301). SSRS diameter is a protective factor for gastrointestinal hemorrhage and ascites and a risk factor for hepatic encephalopathy; Blood ammonia decreased and prothrombin time prolonged after treatment in group A ( P<0.05), blood ammonia decreased and albumin increased in group B ( P<0.05). Hemoglobin and bilirubin increased in group C ( P<0.05), blood ammonia and bilirubin decreased and platelets and albumin increased in group D ( P<0.05); Survival analysis showed that the prognosis of groups A and C was related to liver function, and the survival rate of group D was the highest of all ( P<0.05). Conclusions:SSRS embolization is safe and effective, and liver transplantation improves patient survival. Individualized treatment should be selected based on patient symptoms, liver function, and shunt diameter.

Objective:We sought to investigate the clinical characteristics and risk factors of antiphospholipid syndrome (APS) complicated by autoimmune hemolytic anemia (AIHA).Methods:Retrospective anaysis.Three hundred fifteen consecutive patients with APS were enrolled at the Department of Rheumatology of Peking Union Medical College Hospital between May 2017 to May 2021, and their clinical manifestations[including initial symptoms, time interval between APS onset and diagnosis, systemic lupus erythematosus(SLE), thrombotic events, obstetric morbidity, and extra-criteria manifestations] and laboratory test results[including blood routine, antiphospholipid antibodies(aPLs), blood lipid profile, homocysteine, anti-nuclear antibody profile, immunoglobulin levels, and complement levels] were collected. Then, univariate and multivariate logistic regression analyses were performed. Clinical features and risk factors were analyzed using univariable and multivariable logistic regression analysis.Results:Among 315 APS patients, 37 cases (11.7%) were complicated by AIHA, and AIHA was the first manifestation or co-occurrence. The median time interval between APS onset and diagnosis was 12 months. The proportion of SLE in APS patients combined with AIHA was higher than that in APS patients without AIHA[62.2%(23/37) vs. 19.4%(54/278), P<0.001]. There was no significant difference in the proportions of thrombosis and pregnancy morbidity between the two groups. In terms of extra-criteria manifestations, APS patients with AIHA had a significantly ( P<0.05) greater risk of thrombocytopenia ( OR=6.19, 95% CI 2.81-13.65) and higher proportions of hypocomplementemia, a positive lupus anticoagulant (LA) result, double aPLs positivity[i.e., any two of the following antibodies were positive: LA, anticardilolipin antibody(aCL), and anti-β2 glycoprotein Ⅰ(β2GPⅠ)], and triple aPLs positivity (i.e., LA, aCL, and anti-β2GPⅠ antibodies were all positive). Multivariate logistic regression analysis showed that SLE ( OR=3.46,95% CI 1.60-7.48), thrombocytopenia ( OR=2.56,95% CI 1.15-5.67), and hypocomplementemia ( OR=4.29,95% CI 2.03-9.04) were independent risk factors for the complication of APS. In the primary APS subgroup, multivariate logistic regression analysis showed that livedo reticularis ( OR=10.51,95%CI 1.06-103.78), thrombocytopenia ( OR=3.77, 95% CI 1.23-11.57), and hypocomplementemia ( OR=5.92,95% CI 1.95-17.95) were independent risk factors for the complication of APS. Conclusions:AIHA is not rare in APS patients; moreover, it occurs more frequently in APS secondary to SLE and is more likely to present with a variety of extra-criteria manifestations. Patients with AIHA should be promptly tested for antiphospholipid antibody profiles and alerted to the possibility of thrombotic events.

Objective: To analyze and evaluate the clinical application effect of bioceramic material mineral trioxide aggregate and iRoot BP plus on the formation of apical barrier in adult teeth with incomplete apical foramen. Methods: A total of 200 permanent teeth with apical periodontitis whose apical foramen were not closed were randomly divided into two groups, and the apical barrier was prepared with MTA and iRoot BP plus, respectively. The operation time of MTA and iRoot BP plus and effects of different types of apical foramen destruction, lesion range of apical area, the filling of apical area and patients' age on the treatment success rate was analyzed and compared. Results: The operation time of preparing apical barrier in iRoot BP plus group was shorter than that in MTA group, and the difference was statistically significant (P<0.05). However, different types of apical foramen destruction, lesion scope of apical area, filling of apical area and patients' age had no effect on the treatment success rate of the two groups (P>0.05). Conclusion The clinical effects of MTA and iRoot BP plus in the treatment of apical periodontitis of permanent teeth with unclosed apical foramen are similar, but the operation performance of iRoot BP plus is better.

Glucose monitoring is an important part of medical care in diabetes mellitus, which not only helps assess glycemic control and treatment safety, but also assists with treatment adjustment. With the development of continuous glucose monitoring (CGM), the use of CGM has increased rapidly. With the wealth of glucose data produced by CGM, new metrics are greatly needed to optimally evaluate glucose status and guide the treatment. One of the parameters that CGM provides, time in range (TIR), has been recognized as a key metric by the international consensus. Before the adoption of TIR in clinical practice, several issues including the minimum length of CGM use, the setting of the target range, and individualized TIR goals are summarized. Additionally, we discussed the mounting evidence supporting the association between TIR and diabetes-related outcomes. As a novel glucose metric, it is of interest to compare TIR with other conventional glucose markers such as glycated hemoglobin A1c. It is anticipated that the use of TIR may provide further information on the quality of glucose control and lead to improved diabetes management.

Objective To study the influencing factors of blood stasis constitution and provide a basis for treating blood stasis-related diseases by traditional Chinese medicine (TCM) constitution identification. Methods Data were collected using the self-developed TCM constitution identification platform based on B/S model by the project team. The obtained data were divided into blood stasis constitution and normal constitution groups. The differences of the categorical type influencing factors (gender, birth mode, feeding mode within four months of birth, family history, marital status, eating habits, sleeping habits, exercise habits, emotional state, stress situation, and living environment) and the quantitative type influencing factors (sleep time, age, and mother's age at birth) on the constitution of the two groups were analyzed. In the single-factor analysis, the Pearson's chi-square test was selected for the categorical variable, and the independent sample t test and Mann-Whitney U nonparametric test were selected for the quantitative variables according to whether they conformed to the positive-terrestrial distribution; the binary logistic stepwise regression method was selected for the multi-factor analysis. Results The data of 318 cases were collected from the TCM composition identification platform, and 159 cases of blood stasis constitution were used as the experimental group and 159 cases of normal constitution were used as the control group. The Pearson's chi-square test yielded significant differences (P < 0.05) in the effects of gender, pressure situation, family history, living environment, emotional state, exercise habits, and dietary habits on blood stasis constitution. The independent samples t test yielded differences in sleep duration between the blood stasis constitution and normal constitution populations (P < 0.05), which meant sleep duration of the blood stasis constitution population was less than that of the normal constitution population. The Mann-Whitney U nonparametric test results accepted the original hypothesis that there was no difference in the distribution of age and mother’s age at birth across constitution types (P > 0.05). Binary logistic regression analysis showed that gender, family history, marital status, living environment, exercise habits, and emotional state were risk factors for blood stasis constitution (P < 0.05). Conclusion Gender, family history, living environment, emotional state, and exercise habits were significant influencing factors of blood stasis constitution. Blood stasis constitution populations can pay more attention to these influencing factors in their daily life for the prevention and reconciliation of blood stasis constitution.

Objective: To understand the current situation and associated factors of cellphone usage and addiction among Chinese children and adolescents, to provide reference for effective prevention and intervention of cellphone addiction. Methods: Using a stratified random sampling approach, 11 213 children and adolescents and their parents from 31 provinces, municipalities and autonomous regions in China were recruited and surveyed. Results: The median of daily mobile phone use time among Chinese children and adolescents were 120.00 minutes, as reported by either children or parents. Child s age( β =0.12), hedonic( β =0.11) and social( β =0.09) cellphone use motivations positively related to time spent on cellphone( P <0.01). Cellphone related parental communication( β =-0.06) and knowledge( β =-0.03), as well as cellphone usage on instrumental( β =-0.04) or self representation( β =-0.16) motivation negatively related to time spent on cellphone( P <0.05). Child s age( β =-0.04), cellphone related parental communication( β =-0.09) and awareness( β =-0.14), cellphone use on instrumental motivation( β =-0.22) were negatively associated with cellphone addiction among children and adolescents( P <0.05). Cellphone related parental monitoring( β =0.07), as well as cellphone usage on self representation motivation( β =0.03) or hedonic motivation( β =0.29) positively related to cellphone addiction in children and adolescents( P <0.05). Conclusion Time spent on mobile phone and mobile phone addiction of Chinese children and adolescents are influenced by various internal and external factors, such as the mobile phone use motivation and parenting style.Future school education should help children develop scientific motivation for mobile phone use. Family education should help parents develop positive parenting behaviors such as communication and awareness, so as to reduce the possibility of improper mobile phone use.
