Clinical characteristics of in-hospital cardiac arrest in emergency patients in Kashgar area and analysis of influencing factors on success rate of cardiopulmonary resuscitation / 中华危重病急救医学

OBJECTIVE@#To analyze the clinical characteristics of patients with emergency in-hospital cardiac arrest (IHCA) in Kashgar, Xinjiang Uygur Autonomous Region and the factors affecting the success rate of cardiopulmonary resuscitation.@*METHODS@#Retrospectively selected patients who had cardiac arrest and cardiopulmonary resuscitation in the emergency department of the People's Hospital of 6 counties and cities in Kashgar area from January 2019 to January 2022. The clinical data of all patients were collected, including gender, age, major underlying diseases, the beginning and duration of resuscitation, the number of electric defibrillation acute physiology and chronic health evaluation II (APACHE II). According to whether the resuscitation was successful, all patients were divided into successful resuscitation group and failed resuscitation group. The clinical characteristics of the two groups were compared. Then, the influencing factors of the success rate of cardiopulmonary resuscitation in IHCA patients were analyzed by binary Logistic regression.@*RESULTS@#A total of 1 376 patients were enrolled, including 1 117 cases of failed resuscitation and 259 cases of successful resuscitation. The success rate of resuscitation was 18.82%. Compared with the resuscitation failure group, the patients in the successful resuscitation group were younger (age: 49.10±20.99 vs. 58.44±18.32), the resuscitation start time was earlier [resuscitation start time ≤ 5 minutes: 76.45% (198/259) vs. 66.61% (744/1 117)], the proportion of cardiovascular and cerebrovascular diseases was lower [cardiovascular disease: 49.42% (128/259) vs. 58.19% (650/1 117), cerebrovascular disease: 17.37% (45/259) vs. 21.58% (241/1 117)], the number of electric defibrillation was lower [times: 0 (0, 2) vs. 1 (0, 1)], the proportion of endotracheal intubation was more [80.31% (208/259) vs. 55.60% (621/1 117)], APACHE II score was lower (13.75±8.03 vs. 17.90±4.63), and the difference was statistically significant (all P < 0.01). Binary Logistic regression analysis showed that age, start time of resuscitation, ventilation mode and APACHE II score were protective factors affecting the success rate of cardiopulmonary resuscitation in patients with emergency IHCA [age: odds ratio (OR) = 0.982, 95% confidence interval (95%CI) was 0.973-0.991, P < 0.001; resuscitation start time ≤ 5 minutes: OR = 0.629, 95%CI was 0.409-0.966, P = 0.034; tracheal intubation assisted ventilation: OR = 0.243, 95%CI was 0.149-0.397, P < 0.001; low APACHE II score: OR = 0.871, 95%CI was 0.836-0.907, P < 0.001], while underlying diseases (cardiovascular diseases) are a risk factor affecting the success rate of cardiopulmonary resuscitation (OR = 1.190, 95%CI was 1.015-1.395, P = 0.036).@*CONCLUSIONS@#Age, resuscitation start time, ventilation mode, APACHE II score and major underlying diseases (cardiovascular diseases) have a greater impact on the success rate of resuscitation in IHCA patients. The above factors are conducive to improving or formulating more effective rescue strategies for IHCA patients, so as to achieve the purpose of improving the success rate of clinical treatment.

Levels of base excision repair proteins in CD4+ T cells in patients with systemic lupus erythematosus / 中南大学学报(医学版)

OBJECTIVES@#Systemic lupus erythematosus (SLE) is a multi-systemic disease with the unknown pathogenic mechanism. DNA demethylation is involved in SLE pathogenesis. Growth arrest and DNA damage inducible 45 alpha (Gadd45a) takes part in the process of DNA demethylation. Gadd45a is a DNA repair-related protein. This study aims to investigate the expressions of some proteins [including activation-induced cytidine deaminase (AID), thymine DNA glycosylase (TDG), and methyl-CpG-binding domain protein 4 (MBD4)] involving in base excision repair (BER) process in CD4+ T cells in patients with SLE, and to analyze the correlations between the above BER proteins and lupus disease.@*METHODS@#From January 2019 to September 2020, 12 SLE patients and 12 healthy controls were recruited from Second Xiangya Hospital of Central South University. Peripheral blood mononuclear cells (PBMCs) were separated by Ficoll-Hypaque density gradient centrifugation and then CD4+ T cells were isolated via positive selection using Miltenyi beads. We measured the messenger RNA (mRNA) and protein expressions of AID, TDG, and MBD4 by real-time reverse transcription polymerase chain reaction (RT-PCR) and Western blotting, respectively.@*RESULTS@#In contrast to controls, in SLE CD4+ T cells, the mRNA and protein expressions of AID were elevated (P=0.003, P=0.022, respectively); TDG protein expression was increased (P=0.017); and MBD4 protein level was reduced (P<0.001). No visible distinctions was found in the mRNA expressions of either TDG or MBD4 between the 2 groups (both P>0.05). The mRNA and protein expressions of AID and the protein levels of TDG were positively correlated with SLE disease activity index (SLEDAI). And the mRNA and protein expressions of MBD4 were negatively correlated with SLEDAI.@*CONCLUSIONS@#In SLE CD4+ T cells, the increased expressions of AID and TDG and the decreased MBD4 expression may participate in SLE pathogenic mechanism.

Induced pluripotent stem cell-derived motor neurons from amyotrophic lateral sclerosis (ALS) patients carrying different superoxide dismutase 1 mutations recapitulate pathological features of ALS / 中华医学杂志(英文版)

BACKGROUND@#Investigations of the pathogenic mechanisms in motor neurons (MNs) derived from amyotrophic lateral sclerosis (ALS) disease-specific induced pluripotent stem (iPS) cell lines could improve understanding of the issues affecting MNs. Therefore, in this study we explored mutant superoxide dismutase 1 (SOD1) protein expression in MNs derived from the iPS cell lines of ALS patients carrying different SOD1 mutations.@*METHODS@#We generated induced pluripotent stem cell (iPSC) lines from two familial ALS (FALS) patients with SOD1-V14M and SOD1-C111Y mutations, and then differentiated them into MNs. We investigated levels of the SOD1 protein in iPSCs and MNs, the intracellular Ca2+ levels in MNs, and the lactate dehydrogenase (LDH) activity in the process of differentiation into the MNs derived from the controls and ALS patients' iPSCs.@*RESULTS@#The iPSCs from the two FALS patients were capable of differentiation into MNs carrying different SOD1 mutations and differentially expressed MN markers. We detected high SOD1 protein expression and high intracellular calcium levels in both the MN and iPSCs that were derived from the two SOD1 mutant patients. However, at no time did we observe stronger LDH activity in the patient lines compared with the control lines.@*CONCLUSIONS@#MNs derived from patient-specific iPSC lines can recapitulate key aspects of ALS pathogenesis, providing a cell-based disease model to further elucidate disease pathogenesis and explore gene repair coupled with cell-replacement therapy. Incremental mutant expressions of SOD1 in MNs may have disrupted MN function, either causing or contributing to the intracellular calcium disturbances, which could lead to the occurrence and development of the disease.

BACKGROUND@#Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder associated with loss of motor neurons. Our objective was to explore the epidemiology, clinical features, and survival factors of 1809 patients with ALS.@*METHODS@#We analyzed 1809 ALS patients, who were recruited from the Peking University Third Hospital from January 2005 to December 2015. Demographic data and disease-related parameters were collected. Kaplan-Meier curves were used to compare survival time. Cox proportional hazards function and the hazard ratio were used to identify adjusted prognostic predictors.@*RESULTS@#The results showed that the average annual incidence in Beijing alone was 0.38 cases/100,000 person-years and the mean age of onset was 48.88 ± 11.35 (95% confidence interval [CI]: 48.17-49.85) years. The median survival time from onset to death/tracheostomy was 58.89 ± 33.03 (95% CI: 51.46-63.84) months. In the adjusted Cox proportional hazard model, age of onset, diagnosis delay, rate of disease progression (Amyotrophic Lateral Sclerosis Functional Rating Scale Revised decline [points/month]), and body mass index all had an independent effect on survival in ALS.@*CONCLUSIONS@#Our study provides information on epidemiology, clinical features, and survival factors of patients with ALS in China. These results can be helpful in clinical practice, clinical trial design, and validation of new tools to predict disease progression.

Epidemiological features and mechanism of coronavirus disease 2019 in children / 中国当代儿科杂志

Compared with adults, children tend to have lower incidence rate, hospitalization rate, and mortality rate of coronavirus disease 2019 (COVID-19), while the cause of such age-based differences in disease severity remains unclear. An investigation of pathogenesis in children may help to analyze the therapies for the high-risk population. Human angiotensin-converting enzyme Ⅱ is the main receptor of severe acute respiratory syndrome coronavirus 2 and can limit pulmonary capillary leakage and inflammation mediated by angiotensin 2 and exert a protective effect against acute lung injury. Its expression decreases with age. Regular vaccination and frequent upper respiratory virus infection in children can lead to regular immune activation, and its combination with strong innate immunity can help to achieve virus clearance in the early stage of infection in children with COVID-19. Meanwhile, there are strong regeneration and repair abilities of alveolar epithelial cells in children, which may help with the early recovery of infection. In addition, risk factors, such as underlying cardiopulmonary diseases, obesity, and smoking, are relatively uncommon in children. Social factors, including home quarantine and timely closure of schools, may help to reduce the infection rate in children. However, children with immunodeficiency are a high-risk population and should be closely monitored. Further studies are needed to investigate the immune and protection mechanisms against COVID-19 in children.

APOBEC3B mediated the resistance to cisplatin in non-small cell lung carcinoma / 中国医师杂志

Objective:APOBEC3B (A3B) is an important member of the apolipoprotein B mRNA editing enzyme catalytic polypeptide (APOBEC) family. The study aims to investigate the relationship between A3B expression and prognosis as well as resistance to cisplatin in non-small cell lung cancer (NSCLC).Methods:Real-time quantitative polymerase chain reaction (qRT-PCR) was used to analysis the A3B mRNA expression in 40 NSCLC tissues; Kaplan Meier plotter was used to analyse the correlation between A3B expression and clinical prognosis; in addition, the knock-down A3B expression cell line in human lung adenocarcinoma cell A549 was constructed; MTS and plate cloning experiment were performed to observe the changes in cell cisplatin sensitivity, and γ-H2AX immunofluorescence was used to quantitate the DNA damage.Results:Compared with adjacent tissues, A3B was highly expressed in NSCLC tissues (27/40). Kaplan Meier plotter analysis showed that A3B expression was positively correlated with NSCLC overall survival (OS) [adenocarcinoma: HR=0.64(0.47-0.86), P=0.002 6; squamous cell carcinoma: HR=0.77(0.59-1.01), P=0.006]. Cell-based studies showed that the knock-down A3B expression contributed to sensitivity to cisplatin in A549 cells. Conclusions:A3B mediates the sensitivity of lung cancer to cisplatin. This effect may partly explain why NSCLC patients with high A3B expression have a better prognosis.

Roles of cyclins in the progression of spermatogenesis / 中华男科学杂志

Spermatogenesis is a complex and precise process of differentiation of germ cells, which involves three stages: mitosis of spermatogonia, meiosis of spermatocytes and formation of spermatozoa. The process is controlled by many factors, including regulation of cyclins in spermatogenic cells, which plays a pivotal role. Cyclins form heterologous dimer compounds with protein kinase activity by binding to cyclin-dependent kinases, then phosphorylate multiple proteins and promote the orderly conduct of each phase of the cell cycle. In recent years, cyclins A, B, D and E have been found to play important roles in the regulation of spermatogenesis. This article presents an overview on the roles of these four cyclins in regulating the progression of spermatogenesis.

To assess the value of immunohistochemical analysis for expressions of C3d, C4d, IgG, IgG4, and CD123 in the diagnosis of autoimmune skin diseases.
 Methods: We investigated the expressions of C3d, C4d, IgG, IgG4, and CD123 in paraffin-embedded, formalin-fixed tissues from 27 lupus erythematosus cases, including 8 discoid lupus erythematosus (DLE) cases, 4 subacute cutaneous lupus erythematosus (SCLE) cases, and 15 systemic lupus erythematosus (SLE) cases. Tissues from 15 dermatomyositis (DM) cases, 15 bullous pemphigoid (BP) cases, and 15 pemphigus cases were examined by immunohistochemical analysis. The differences in expression rates of C3d, C4d, IgG, IgG4, and CD123 between immunohistochemical staining and direct immunofluorescence were compared in the diagnosis of these diseases.
 Results: In the lupus erythematosus group, the positive rates of C3d and C4d deposited along the dermoepidermal junction were 85.2% and 51.9%, respectively. In the dermatomyositis group, the positive rates of C3d and C4d deposited along the dermoepidermal junction were 40% and 0, respectively. The expressions of C3d and C4d in lupus erythematosus tissues were significantly higher than those in DM tissues (P<0.05). The expression of CD123 protein in skin lesions of the lupus group was significantly higher than that in the DM group (P<0.05). In the BP group, the positive rates of C3d and C4d deposited along the dermoepidermal junction were 100% and 86.7%, respectively. In the pemphigus group, the positive rates of C3d and C4d deposited in the intercellular space of keratinocytes were 100% and 60%, respectively. The expressions of IgG and IgG4 in pemphigus tissues were higher than those in BP tissues (P<0.05). And the ratios of IgG4 to IgG in the pemphigus group was significantly higher than that in the BP group (P<0.05).
 Conclusion: The assays of C3d and C4d define an important diagnostic adjunct in evaluation of lupus erythematosus, BP and pemphigus. In some cases, it may even replace the direct immunofluorescence as a diagnostic adjunct. The expression of CD123 possesses certain clinical significance for the differential diagnosis of lupus erythematosus, and IgG4 and IgG expressions have adjunctive diagnostic significance for pemphigus.
