Objective:To investigate the effects of overexpression of Nkx2.5 gene on the anti apoptotic ability of bone marrow mesenchymal stem cells (BMSCs) and cardiac function after myocardial infarction.Methods:A cell ischemia model was established by culturing cells under oxygen glucose deprivation/reoxygenat (OGD/R) conditions. The experiment was divided into four groups: bone marrow mesenchymal stem cells cultured under normal conditions (BMSC group), BMSC group cultured under glucose and oxygen deprivation (BMSC+OGD/R group), overexpressed empty vector BMSC group cultured under glucose and oxygen deprivation(BMSC NC+OGD/R group), and overexpressed Nkx2.5 BMSC group cultured under glucose and oxygen deprivation (BMSC Nkx2.5+OGD/R group). The apoptosis rate of BMSCs in each group was detected via flow cytometry, and BMSC protein was extracted. The expression of caspase-3 and pro-caspase-3, caspase-8 and pro-caspase-8, caspase-9, and cytochrome C protein and expression of Nkx2.5 in the BMSCs of each group were detected by Western blot to determine the anti-apoptotic pathway in vitro. The model of myocardial infarction in mice was established by ligating the left anterior descending branch of coronary artery. The experiment was divided into five groups: sham surgery group, myocardial infarction untreated group, myocardial infarction tail vein injection of BMSC group, myocardial infarction tail vein injection of BMSC empty body group, myocardial infarction tail vein injection of BMSC overexpression Nkx2.5 group. The changes of cardiac function in mice were evaluated by echocardiography. Normal distribution econometric data were compared between groups using convenient analysis, and pairwise comparisons were conducted using LSD-t test. Results:The apoptosis rate of the BMSC+OGD/R group (12.98±1.24)% was higher than that of the BMSC group (7.82±0.42)%, and the difference was statistically significant ( P<0.001). The apoptosis rate of the BMSC NKx2.5+OGD/R group (11.26±0.22)% was lower than that of the BMSC+OGD/R group (12.98±1.24)% and the BMSC NC+OGD/R group (13.14±0.70)%, with statistically significant differences ( P<0.05). Compared to BMSC group ((0.36±0.08), (1.13±0.04), (0.36±0.06), (1.12±0.13), (1.23±0.08), (0.60±0.05), (0.67±0.14)), BMSC+OGD/R group ((1.05±0.10), (0.62±0.04), (1.07±0.09), (0.57±0.07), (0.55±0.08), (1.25±0.09), (0.71±0.04)) and BMSC NC+OGD/R group ((1.16±0.16), (0.64±0.06), (1.19±0.16), (0.56±0.06), (0.50±0.06), (1.28±0.06), (0.73±0.04)), the expression of Caspase-3 (0.72±0.08) and pro-caspase-3(0.89±0.09), Caspase-8 (0.63±0.08) and pro-caspase-8(0.85±0.12), Caspase-9 (0.87±0.09), cytochrome C (0.91±0.10), and Nkx2.5 (1.54±0.16) in BMSC Nkx2.5+OGD/R group was statistically significant (all P<0.05). In vivo experiments showed that the heart ejection fraction (29.05±7.07)% of mice treated with BMSC Nkx2.5 after myocardial infarction was significantly improved compared to the BMSC group (16.57±2.09)% and BMSC NC group (18.08±3.27)% (all P<0.05). Conclusion:BMSC Nkx2.5 may enhance the anti-apoptosis ability of BMSCs and improve cardiac function after myocardial infarction by inhibiting the death receptor pathway and the mitochondrial signal pathway .

Objective:To explore the role of ductular reaction in assessing the efficacy of liver transplantation.Method:From January 2015 to December 2020, he relevant clinical data were retrospectively reviewed for 100 recipients and their corresponding donors at Shulan (Hangzhou) Hospital. They were assigned into two groups of hepatic steatosis (HS group, 65 cases) and non-hepatic steatosis (non-HS group, 35 cases) according to whether or not receiving steatosis donated liver. Furthermore, based upon the occurrence of early allograft dysfunction (EAD), the participants were categorized into two groups of EAD (33 cases) and non-EAD (67 cases). The degree of bile duct reaction ductular reaction was defined by the percentage of staining area occupied by cytokeratin 19 (CK19) -positive bile duct cells in immunohistochemical-stained specimens. Donor of ductular reaction were compared between HS/non-HS and EAD/non-EAD groups. The risk factors for EAD were identified by univariate and multivariate Logistic regression analysis. Subgroup analysis was conducted based upon the level of ductular reaction (DR number) in donors (DR=0.4 as a threshold) and whether or not donors exhibited steatosis. The impact of DR was examined on the incidence of EAD and survival post-liver transplantation in steatosis donors.Result:The level of DR was higher in steatosis donor than that in non-steatosis donor [ (0.59%±0.385%) vs. (0.32%±0.194%), P<0.01]. And it was higher in EAD group than that in non-EAD group [ (0.72%±0.449%) vs. (0.38%±0.226%), P<0.01]. Multivariate logistic regression analysis showed that a high level of ductular reaction was an independent risk factor for EAD post-liver transplantation in donor. Subgroup analysis revealed that receiving a steatosis donor with low ductular reaction (DR<0.4%) had comparable levels of EAD occurrence and overall survival rate to receiving a non-steatosis donor. Conclusion:Steatosis with low ductular reaction donor may be safely applied for liver transplantation. And assessing donor injury based upon ductular reaction can effectively expand the clinical application of steatosis donors.

Sepsis is life-threatening with complex pathogenesis. It is a big problem in the medical field. Clinically, antibiotics, hormones and mechanical ventilation are the main treatments. There is a lack of specific therapeutic drugs. The treatment effect is not good. In recent years, more and more progress has been made in the treatment of sepsis with traditional Chinese medicine. This article reviews the etiology, pathogenesis and treatment strategies of sepsis. It focuses on four therapies, including clearing away heat and detoxification, clearing the interior, activating blood circulation and removing blood stasis, and strengthening the foundation. We further discuss the advantages and disadvantages of traditional Chinese medicine in the treatment of sepsis, in order to provide reference for the clinical treatment of sepsis.

Immunoparalysis is the main cause of death in patients with intermediate and terminal sepsis. The correction of immunoparalysis is an important direction of sepsis treatment. In the pathological process of sepsis, a variety of factors contribute to the imbalanced secretion of cytokines, weakened function of antigen-presenting cells, apoptosis and depletion of lymphocytes, and ultimately lead to immunoparalysis, secondary infection, and even patient deaths. Cytokines such as GM-CSF, IFN-γ, IL-7, and IL-15, immune checkpoint-related therapies such as PD-1/PD-L1 antibodies, CTLA-4 antibodies, TIM-3 antibodies, and LAG-3 antibodies, and immunoreactive substances such as thymosin α1 and immunoglobulin might be beneficial to correct the immune paralysis of patients. the progress of immunotherapy to correct immune paralysis in sepsis were reviewed in this article.

Objective:To investigate the efficacy of flexion-lateral curvature-supination reduction combined with primary anterior surgery for the treatment of lower cervical dislocation with unilateral facet inter-locking.Methods:A retrospective analysis was performed in the 32 patients who had been admitted to Department of Spine Surgery, Honghui Hospital for lower cervical dislocation with unilateral facet interlocking from November 2015 to October 2018. According to their treatments, they were divided into 2 groups. In the emergency group treated by flexion-lateral curvature-supination reduction combined with primary anterior surgery, there were 13 males and 3 females, aged from 24 to 63 years. In the traction group treated by cranial traction reduction combined with secondary anterior surgery, there were 12 males and 4 females, aged from 20 to 64 years. The operation time, intraoperative blood loss, hospital stay, bone graft fusion, American Spinal Injury Association (ASIA) grade and Japanese Orthopaedic Association (JOA) score were compared between the 2 groups.Results:There was no significant difference in the preoperative general data between the 2 groups, showing they were comparable ( P<0.05). All patients were followed up from 26 to 40 months. The hospital stay for the emergency group [(7.2±1.2) d] was significantly shorter than that for the traction group[(10.9±1.2) d] ( P<0.05). There was no significant difference in the operation time, blood loss, ASIA grade or JOA score between the 2 groups ( P>0.05). All patients achieved osseous fusion of intervertebral space. Conclusion:Compared with traditional methods, flexion-lateral curvature-supination reduction combined with primay anterior surgery shows no significant difference in the recovery of neurological function but leads to a shorter hospital stay.

OBJECTIVETo explore the clinical and genetic characteristics of patients with dentatorubro-pallidoluysian atrophy (DRPLA).

METHODSDNA analysis for DRPLA gene was performed in two patients. Clinical features and genetic testing of Chinese DRPLA patients reported in the literature were reviewed in terms of initial symptoms, CAG repeat and age of onset.

RESULTSBoth families were confirmed by genetic analysis. In family 1, the number of CAG repeat in the proband, his brother and his mother was determined respectively as 8/65, 8/53 and 8/18. In family 2, the number of CAG repeat was respectively 13/63, 13/18, 18/52 and 13/13 in the proband, his brother, his father and his mother. The size of the expanded CAG repeats has inversely correlated with the age at onset (P<0.05, r=- 0.555). The age at onset of epilepsy was 10 and that for the onset of ataxia is forty years in initial symptom.

CONCLUSIONThe clinical characteristics of DRPLA include epilepsy, ataxia and cognitive impairment. The initial symptoms are epilepsy in adolescence and ataxia in adults. The size of expanded CAG repeats inversely correlates with the age at onset. The initial symptoms are different with different age of onset. It is difficult to diagnose DRPLA at an early stage.
