Objective To investigate the effect efficacy of integrated traditional Chinese and western medicine on intestinal mucosal permeability in the patients with diarrhea after chemotherapy for lung cancer. Methods From January 2016 to June 2017, 78 patients with diarrhea after chemotherapy for lung cancer who were treated in the outpatient clinic or during hospitalization were selected, and were randomly divided into integrated Chinese and western medicine group and western medicine group. The patients in the western medicine group were given montmorillonite powder, rehydration (intravenous or oral) to correct water and electrolyte acid-base balance disorders and other western conventional treatments. The integrated Chinese and western medicine group was further given modified Shaoyao Decoction on the basis of the western group. Both groups were given the dosage for 72h. The changes of serum ET, D-lactate and TNF-a before and after treatment were determined and compared between the two groups, and the clinical effect was compared. Results After 72 hours of treatment, the levels of serum ET, D-lactate and TNF-a indices in the two groups were significantly decreased (P＜0. 05 or P＜0. 01). And in the degree of decrease, the integrated Chinese and western medicine group was more significant than the western medicine group (P＜0. 05); at the same time, the total effective rate in the integrated Chinese and western medicine group was higher than that in the western medicine group (χ2=4. 52, P＜ 0. 05). Conclusion Integrated Chinese and western medicine in the treatment of diarrhea after chemotherapy for lung cancer has more positive effects, which can significantly reduce the serum ET, D-lactic acid and TNF-a, and protect the intestinal mucosal barrier to reduce its permeability.

IIn recent years, an increasing trend of the birth prevalence of anotia/microtia is observed in China, contributed by changes of social environment and lifestyle. There seems to be no major breakthroughs in exact pathogenesis of microtia, though the research results related to molecular genetics unceasingly appear. Animal studies have important implications for exploring the pathophysiologic mechanism of microtia. In this review, we focused on the types and modeling approaches of animal models, as well as the advantages and disadvantages respectively. We believe that this review will provide references for researchers to select and establish appropriate animal models.

Objective:To observe the feasibility of evaluating right ventricular (RV) function by the method based on left ventricle (LV) pressure-strain ring (PSL) technique in patients with systemic lupus erythematosus (SLE), and to evaluate the efficacy of non-invasive PSL in the diagnosis of dysfunction of both LV and RV.Methods:Thirty-nine patients were enrolled with SLE who were admitted to the Affiliated Hospital of Inner Mongolia Medical University from March 2020 to September 2021 and 57 sex- and age-matched healthy controls underwent assessment by conventional echocardiography, two-dimensional speckle tracking imaging (2D-STI) and myocardial work (MW). The echocardiographic parameters were compared between the groups. The correlations between RVMW parameters and conventional echocardiographic parameters, and between MW parameters and SLEDAI-2K score were analyzed by Spearman correlation analysis.Results:①The two groups did not show any difference at the conventional echocardiographic parameters of the LV systolic function ( P>0.05). In the SLE group, tricuspid regurgitation maximal velocity (TR V max) and right ventricular index of myocardial performance (RIMP) increased, tricuspid annular plane systolic excursion (TAPSE) and tricuspid annular S′ (S′ tv) decreased (all P<0.05), and others did not show statistical difference (all P>0.05). ②The 2D-STI parameters: There were no significant differences in left ventricular global longitudinal strain (LV GLS) ( P>0.05), however RVGLS decreased ( P<0.05). ③The MW parameters of LV and RV: including global constructive work (GCW), global work index (GWI), global wasted work (GWW), and global work efficiency (GWE). In SLE group, LV GWE, RV GWE decreased and LV GWW, RV GWW increased ( P<0.05), others were no significant differences ( P>0.05). ④The correlation analysis: RV GWI positively correlated with TR V max ( rs=0.481). RV GCW positively correlated with TR V max ( rs=0.587). RV GWW positively correlated with right atrial area (RAA) and TR V max ( rs=0.429, 0.610), negatively correlated with S′ tv ( rs=-0.342). RV GWE positively correlated with S′ tv ( rs=0.326) and negatively correlated with RAA ( rs=-0.462) (all P<0.05). SLEDAI-2K score was negatively correlated with LV GLS ( rs=-0.333) and LV GWI ( rs=-0.326) ( P<0.05). Conclusions:The study has shown the impaired systolic function of both LV and RV in patients with SLE. PSL technique, especially RVMV based on LV PSL technique might emerged as a novel measure to evaluate systolic dysfunction in SLE patients.

Autoantibody-related congenital heart block (ACHB) is a passively acquired autoimmune disease developing in fetuses after exposuring to maternal anti-Ro/Sj?gren's syndrome type A (SSA) antibody and/or anti-La/SSB antibody transported across the placenta, which contributes to fetal heart conduction system damage and signal conduction block at the atrioventricular node. However, fetal atrioventricular block does not necessarily occur with the presence of maternal autoantibodies, indicating its complex pathogenesis. This review focuses on the theories of calcium channels and apoptosis, the influence of other maternal factors and environmental changes on ACHB and the roles of natural killer cells and human leukocyte antigen in ACHB, aiming to provide reference for further study on the pathogenesis.

Objective    To analyze the differences in proteins between aneurysm/dissection patients and healthy subjects, and subsequently figure out differential proteins related to medial degeneration of aortic aneurysm/dissection. Methods    Aortic wall samples were collected from 6 male aortic aneurysm patients (an aortic aneurysm group, mean age 56.50±8.19 years), 6 male aortic dissection patients (an aortic dissection group, mean age 54.17±6.68 years) and 6 male healthy subjects (a normal group, mean age 40.50±9.31 years) between December 2019 and May 2020 in West China Hospital of Sichuan University. Quantitative proteomics was performed using tandem mass tag (TMT) techniques, followed by gene ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis. Results    A total of 63 differential proteins were obtained both in the aortic aneurysm group and the aortic dissection group compared with the normal group, with 30 up-regulating and 33 down-regulating. The differential proteins were involved in multiple biological processes and clusted on peroxisome proliferators-activated receptor (PPAR) signaling pathway, extracellular matrix-receptor interaction signaling pathway and complement and coagulation cascades signaling pathway. Conclusion    The identified proteins may help to demonstrate new molecular mechanisms related to medial degeneration of aortic aneurysm/dissection.

The conventional total arch replacement (cTAR) with frozen elephant trunk implantation is commonly regarded as the gold standard for aortic pathologies involving ascending aorta and proximal aortic arch. By combining open supra-aortic vessels debranching and emerging endovascular technologies, hybrid arch repair (HAR) has been increasingly performed as a promising alternative in risky patients with comorbidities and frailties. Nevertheless, the advantages or disadvantages of hybrid arch procedures and cTAR in terms of survival and related outcomes remain controversial. This study is aimed to briefly review the role and results of HAR in the management of aortic arch pathology in comparison of contemporary cTAR.
