Systemic lupus erythematosus associated macrophage activation syndrome with neuropsychiatric symptoms: A report of 2 cases / 北京大学学报(医学版)

Systemic lupus erythematosus (SLE) associated macrophage activation syndrome (MAS) is clinically severe, with a high mortality rate and rare neuropsychiatric symptoms. In the course of diagnosis and treatment, it is necessary to actively determine whether the neuropsychiatric symptoms in patients are caused by neuropsychiatric systemic lupus erythematosus (NPSLE) or macrophage activation syndrome. This paper retrospectively analyzed the clinical data of 2 cases of SLE associated MAS with neuropsychiatric lesions, Case 1: A 30-year-old female had obvious alopecia in 2019, accompanied by emaciation, fatigue and dry mouth. In March 2021, she felt weak legs and fell down, followed by fever and chills without obvious causes. After completing relevant examinations, she was diagnosed with SLE and given symptomatic treatments such as hormones and anti-infection, but the patient still had fever. The relevant examinations showed moderate anemia, elevated ferritin, elevated triglycerides, decreased NK cell activity, and a perforin positivity rate of 4.27%, which led to the diagnosis of "pre-hemophagocytic syndrome (HPS)". In May 2021, the patient showed mental trance and babble, and was diagnosed with "SLE-associated MAS"after completing relevant examinations. After treatment with methylprednisolone, anti-infection and psychotropic drugs, the patient's temperature was normal and mental symptoms improved. Case 2: A 30-year-old female patient developed butterfly erythema on both sides of the nose on her face and several erythema on her neck in June 2019, accompanied by alopecia, oral ulcers, and fever. She was diagnosed with "SLE" after completing relevant examinations, and her condition was relieved after treatment with methylprednisolone and human immunoglobulin. In October 2019, the patient showed apathy, no lethargy, and fever again, accompanied by dizziness and vomiting. The relevant examination indicated moderate anemia, decreased NK cell activity, elevated triglycerides, and elevated ferritin. The patient was considered to be diagnosed with "SLE, NPSLE, and SLE-associated MAS". After treatment with hormones, human immunoglobulin, anti-infection, rituximab (Mabthera), the patient's condition improved and was discharged from the hospital. After discharge, the patient regularly took methylprednisolone tablets (Medrol), and her psychiatric symptoms were still intermittent. In November 2019, she developed symptoms of fever, mania, and delirium, and later turned to an apathetic state, and was given methylprednisolone intravenous drip and olanzapine tablets (Zyprexa) orally. After the mental symptoms improved, she was treated with rituximab (Mabthera). Later, due to repeated infections, she was replaced with Belizumab (Benlysta), and she was recovered from her psychiatric anomalies in March 2021. Through the analysis of clinical symptoms, imaging examination, laboratory examination, treatment course and effect, it is speculated that the neuropsychiatric symptoms of case 1 are more likely to be caused by MAS, and that of case 2 is more likely to be caused by SLE. At present, there is no direct laboratory basis for the identification of the two neuropsychiatric symptoms. The etiology of neuropsychiatric symptoms can be determined by clinical manifestations, imaging manifestations, cerebrospinal fluid detection, and the patient's response to treatment. Early diagnosis is of great significance for guiding clinical treatment, monitoring the condition and judging the prognosis. The good prognosis of the two cases in this paper is closely related to the early diagnosis, treatment and intervention of the disease.

SET8 Inhibition Potentiates Radiotherapy by Suppressing DNA Damage Repair in Carcinomas / 生物医学与环境科学（英文）

Objective@#SET8 is a member of the SET domain-containing family and the only known lysine methyltransferase (KMT) that monomethylates lysine 20 of histone H4 (H4K20me1). SET8 has been implicated in many essential cellular processes, including cell cycle regulation, DNA replication, DNA damage response, and carcinogenesis. There is no conclusive evidence, however, regarding the effect of SET8 on radiotherapy. In the current study we determined the efficacy of SET8 inhibition on radiotherapy of tumors and the underlying mechanism.@*Methods@#First, we explored the radiotherapy benefit of the SET8 expression signature by analyzing clinical data. Then, we measured a series of biological endpoints, including the xenograft tumor growth in mice and apoptosis, frequency of micronuclei, and foci of 53BP1 and γ-H2AX in cells to detect the SET8 effects on radiosensitivity. RNA sequencing and subsequent experiments were exploited to verify the mechanism underlying the SET8 effects on radiotherapy.@*Results@#Low expression of SET8 predicted a better benefit to radiotherapy in lung adenocarcinoma (LUAD) and invasive breast carcinoma (BRCA) patients. Furthermore, genetic deletion of SET8 significantly enhanced radiation treatment efficacy in a murine tumor model, and A549 and MCF7 cells; SET8 overexpression decreased the radiosensitivity. SET8 inhibition induced more apoptosis, the frequency of micronuclei, and blocked the kinetics process of DNA damage repair as 53BP1 and γ-H2AX foci remained in cells. Moreover, RNF8 was positively correlated with the SET8 impact on DNA damage repair.@*Conclusion@#Our results demonstrated that SET8 inhibition enhanced radiosensitivity by suppressing DNA damage repair, thus suggesting that SET8 potentiated radiotherapy of carcinomas. As new inhibitors of SET8 are synthesized and tested in preclinical and clinical settings, combining SET8 inhibitors with radiation warrants consideration for precise radiotherapy.

Recommendations for the diagnosis and management of lupus nephritis in China / 中华内科杂志

Lupus nephritis (LN) refers to renal involvement in systemic lupus erythematosus and is characterized by hematuria, proteinuria, edema, hypertension and renal insufficiency. The complete remission rate of proliferative LN remains low using the current induction protocols and LN tends to flare. Scientific and standardized diagnosis and therapy are crucial for the treatment of LN. Therefore, based on the current international and domestic experiences and guidelines, the Chinese Rheumatology Association developed the recommendations of diagnosis and therapy for LN, with the purpose of enhancing efficacy, reducing flare, halting renal progression and improving outcome of LN.

Meso-scale Discovery Assay Detects the Changes of Plasma Cytokine Levels in Mice after Low or High LET Ionizing Irradiation / 生物医学与环境科学（英文）

Objective@#To obtain precise data on the changes in the levels of 29 cytokines in mice after high or low linear energy transfer (LET) irradiation and to develop an accurate model of radiation exposure based on the cytokine levels after irradiation.@*Methods@#Plasma samples harvested from mice at different time points after carbon-ion or X-ray irradiation were analyzed using meso-scale discovery (MSD), a high-throughput and sensitive electrochemiluminescence measurement technique. Dose estimation equations were set up using multiple linear regression analysis.@*Results@#The relative levels of IL-6 at 1 h, IL-5 and IL-6 at 24 h, and IL-5, IL-6 and IL-15 at 7 d after irradiation with two intensities increased dose-dependently. The minimum measured levels of IL-5, IL-6 and IL-15 were up to 4.0076 pg/mL, 16.4538 pg/mL and 0.4150 pg/mL, respectively. In addition, dose estimation models were established and verified.@*Conclusions@#The MSD assay can provide more accurate data regarding the changes in the levels of the cytokines IL-5, IL-6 and IL-15. These cytokines could meet the essential criteria for radiosensitive biomarkers and can be used as radiation indicators. Our prediction models can conveniently and accurately estimate the exposure dose in irradiated organism.

Research advances in the function of T cells at the maternal-fetal interface / 生理学报

Immune tolerance at maternal-fetal interface is the basis for establishment and maintenance of successful pregnancy. T cells are pivotal compositions of uterine decidual immune cells, which are required to mediate anti-infection immunity and protect embryos from external antigens attack. T cells also participate in the complex immune regulation process of maternal acceptance of semi-allogeneic embryos, and play an important role in regulating embryo implantation and maintaining pregnancy. Its dysfunction may lead to early pregnancy failures or mid-late pregnancy complications. This review summarizes the compositions, phenotypic characteristics and functions of decidual T cells at the maternal-fetal interface in recent years, and further describes the regulation of decidual CD4 and CD8 T cells in maternal-fetal immune tolerance as well as the molecular mechanisms of abnormal regulation leading to early pregnancy failures. Through the in-depth understanding the mechanism of maternal-fetal immune regulation, it supplies a novel concept on maternal-fetal immune tolerance and new clues for the immunotherapy of pregnancy-related diseases.

Research advances on adrenergic receptor signaling involved in disease microenvironment through regulation of macrophages / 生理学报

Adrenergic receptor (AR), one of the key receptors for nervous system, plays an important role in the immune microenvironment and the progression of many diseases. In recent years, the regulation of ARs and its signal on macrophages has become a research hotspot. Researchers found that ARs could exert different regulatory functions on macrophages in different microenvironments, which in turn affects occurrence and development of diseases such as tumor, heart failure, obesity, acute injury, infection and pregnancy-related diseases. This review summarizes the expression and functional regulation of ARs on macrophages, and the role of ARs in microenvironment of related diseases, which might provide new ideas for the treatments.

Regulatory mechanisms and therapeutic potential of microglial inhibitors in neuropathic pain and morphine tolerance / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Microglia are important cells involved in the regulation of neuropathic pain (NPP) and morphine tolerance. Information on their plasticity and polarity has been elucidated after determining their physiological structure, but there is still much to learn about the role of this type of cell in NPP and morphine tolerance. Microglia mediate multiple functions in health and disease by controlling damage in the central nervous system (CNS) and endogenous immune responses to disease. Microglial activation can result in altered opioid system activity, and NPP is characterized by resistance to morphine. Here we investigate the regulatory mechanisms of microglia and review the potential of microglial inhibitors for modulating NPP and morphine tolerance. Targeted inhibition of glial activation is a clinically promising approach to the treatment of NPP and the prevention of morphine tolerance. Finally, we suggest directions for future research on microglial inhibitors.

Anti-oxidative protective effect and mechanism of klotho on ischemic brain injury / 药学学报

Present study was designed to investigate the effects and underlying antioxidant mechanism of klotho overexpression through an intracerebroventricular injection of a lentiviral vector that encoded murine klotho (LV-KL) on cerebral ischemia injury. Four weeks after the injection of lentivirus into the lateral ventricle of C57Balc/6J mice, a mouse model of global cerebral ischemia-reperfusion was established by bilateral common carotid artery occlusion (2VO). Klotho overexpression significantly improved neurobehavioral deficits and increased the number of survival neurons in the hippocampal CA1 and caudate putamen subregions. The overexpression also decreased malondialdehyde (MDA) content in brain, while mitochondrial manganese- superoxide dismutase (Mn-SOD) and catalase (CAT) expression in brain were increased. Moreover, klotho overexpression decreased Akt and forkhead box class O1 phosphorylation. These findings suggest that klotho may compensate for its aging-related decline to provide a promising therapeutic approach for the acute ischemic stroke during aging.

Three-dimensional Culture of Human Airway Epithelium in Matrigel for Evaluation of Human Rhinovirus C and Bocavirus Infections / 生物医学与环境科学（英文）

OBJECTIVE@#Newly identified human rhinovirus C (HRV-C) and human bocavirus (HBoV) cannot propagate in vitro in traditional cell culture models; thus obtaining knowledge about these viruses and developing related vaccines are difficult. Therefore, it is necessary to develop a novel platform for the propagation of these types of viruses.@*METHODS@#A platform for culturing human airway epithelia in a three-dimensional (3D) pattern using Matrigel as scaffold was developed. The features of 3D culture were identified by immunochemical staining and transmission electron microscopy. Nucleic acid levels of HRV-C and HBoV in 3D cells at designated time points were quantitated by real-time polymerase chain reaction (PCR). Levels of cytokines, whose secretion was induced by the viruses, were measured by ELISA.@*RESULTS@#Properties of bronchial-like tissues, such as the expression of biomarkers CK5, ZO-1, and PCK, and the development of cilium-like protuberances indicative of the human respiration tract, were observed in 3D-cultured human airway epithelial (HAE) cultures, but not in monolayer-cultured cells. Nucleic acid levels of HRV-C and HBoV and levels of virus-induced cytokines were also measured using the 3D culture system.@*CONCLUSION@#Our data provide a preliminary indication that the 3D culture model of primary epithelia using a Matrigel scaffold in vitro can be used to propagate HRV-C and HBoV.

The Predictive Value of Carbohydrate Antigen-125 for New-onset of Atrial Fibrillation in Patients With Chronic Heart Failure / 中国循环杂志

Objective: To investigate whether serum level of carbohydrate antigen-125 (CA-125) could predict the new-onset of atrial fibrillation (AF) in patients with chronic heart failure (CHF). Methods: A total of 200 CHF patients without previous and current AF admitted in our hospital from 2012-01 to 2016-01 were enrolled. Serum level of CA-125 was examined in all patients at their stable condition. Follow-up study was conducted to observe AF occurrence in order to evaluate the relationship between CA-125 level and new-onset of AF. Results: There were 8 patients died within 6 months, 14 lost contact and 178 finished at least 1 time follow-up at the mean of (20.1±9.9) months (from 6 to 54 months). 40/178 (22％) patients developed new-onset of AF. Compared with sinus rhythm, AF patients had the higher CA-125 level as 108 (44-228) U/ml vs 49 (21-118) U/ml, P=0.001. ROC indicated that CA-125>72.58 U/ml was the optimal cut-off value for predicting new-onset of AF. Single factor analysis indicated that serum CA-125>72.58 U/ml, increased left atrial diameter, right ventricular dilatation, pulmonary hypertension, lower LVEF and moderate to severe mitral regurgitation (MR) had the predictive value for new-onset of AF. With adjusted meaningful single factors, multivariate Cox regression analysis presented that serum CA-125>72.58 U/ml (HR=2.709, 95％ CI 1.308-6.876, P=0.008) and moderate to severe MR were the independent predictors for new-onset of AF. Conclusion: Serum CA-125 level was related to new-onset of AF in CHF patients; the patients with elevated CA-125 had the higher chance to develop new-onset of AF.
