Objective To explore the feasibility of mechanical chest compression to establish a rat model of car?diopulmonary resuscitation ( CPR) . Methods 4?month old healthy male Sprague Dawley rats were randomly divided into control group ( n=6 ) and model group ( n=10 ) . After induction of anaesthesia with 10% chloraldurate ( 3 ml/kg, i. p. ) , tracheal intubation and left femoral artery cannulation were performed. Under electrocardiographic and artery blood pressure monitoring, tracheal obstruction ( TO) was performed to rats in model group. At 2 min after the cardiac arrest ( CA) occurred, CPRs were administered to the rats using a self?made animal chest compressor, which provided chest?com?pression at a rate of 200 bpm. Results Shortly after TO, rats in the model group had respiratory arrest, cyanosis and ar?rhythmia. Electrocardiography indicated that CA occurred within 4-5 min, with a decreased artery systolic blood pressure ( <40 mmHg) and a zero pulse pressure. Return of spontaneous circulation ( ROSC) after the CPR was successfully a?chieved in 8 rats (80%), with a transient reperfusion arrhythmia. Finally, 60% of the rats (n=6) recovered to con?sciousness and survived for 24 hrs. The serum biochemical analysis indicated that there were electrolyte disturbances, aci?dosis, impaired renal functions and increased myocardial enzyme spectrum. Pathological examination revealed cardiac rhab? domyolysis, no?reflow phenomenon in renal glomeruli, decrease of neurons and pulmonary congestion in the model group rats. Conclusions Mechanical chest compression can provide minimal cardiac output for the requirement of CPR incardiac arrestin rats. It is feasible to establish rat CPR model with the mechanical chest compression.

Objective To investigate the epidemiology characteristics of crawfish related rhabdomyolysis (RM) in Nanjing, 2016.Methods Outpatient and inpatient electronic medical system of 21 hospitals in Nanjing during 2016 were retrospectively searched, and all the patients diagnosed with RM were selected. The patients with none crayfish-related RM was excluded. The epidemiology characteristics were depicted. The geographic information system (GIS) was used to collect, manage and analyze the spatial data, to visualize it, to analyze the spatial distribution features of the disease, and to explore the cause of disease prediction. GeoDa 1.8 software was used to analyze the global and local spatial auto-correlation.Results A total of 1183 patients with crawfish related RM were initially screened, excluding 59 patients with RM caused by trauma, severe exercise, heat stroke, myositis, poisoning, drugs, and genetic diseases, and 1124 patients were enrolled. The proportion of men was 36.48% (410/1124) with an incidence of 12.54/100 thousands; while of women was 63.52% (714/1124) with an incidence of 21.86/100 thousands. The median age at onset was 34 (28, 43) years. From July to August, the incidence of crawfish related RM was the highest, accounting for 96.53% of the total number of cases. The top four incidence areas were Pukou (41.54/100 thousands), Jianye (25.94/100 thousands), Qixia (25.73/100 thousands), Gulou (25.04/100 thousands), all of which were adjacent to the Yangtze River. Global spatial autocorrelation analysis showed: MoranI = 0.427,Z = 2.646,P = 0.003, suggesting that the crawfish related RM had positive spatial autocorrelation. The results showed that the spatial structure of crawfish related RM existed in Nanjing in 2016. Local spatial autocorrelation analysis showed that the high-high concentration areas were Pukou, Jianye and Liuhe. The incidences of above three areas which were the Nanjing section of the lower reaches of the Yangtze River flowed through the region and surrounding areas were higher than the overall incidence of Nanjing.Conclusion The prevalence of crawfish related RM in Nanjing during 2016 had an obvious region-concentrated character and global spatial autocorrelation with the high prevalent regions mainly concentrated in the urban areas adjacent to the Yangtze River.

Objective:To explore the effects of estrogen receptor α (ERα) encoded by protein encoding gene ESR1 on the radiation resistance of breast cancer cells and their molecular mechanisms.Methods:The ESR1 overexpression plasmid was transfected into estrogen receptor (ER)-negative breast cancer cells. Then, the shRNA-ESR1 vector was introduced into ER-positive cell to establish models with different phenotype. The ATG5 mRNA level and protein expression levels of LC3B-I, LC3B-II, P62, FIP200, ATG5, ATG7, ATG12, Beclin1, ULK1 were detected using qPCR and Western blot techniques. Cell death was measured using flow cytometry. The radiation sensitivity was determined through the colony formation assay. The mortality of breast cancer cells under the autophagy gene knockdown and overexpression or treated with estrogen receptor inhibitor (TAM) combined with ionizing radiation were detected by trypan blue staining.Results:Under the condition of 8 Gy X-ray irradiation, the knockdown of ESR1 in ER-positive ZR75 breast cancer cells promoted cell death ( t = 3.49, 3.13, P < 0.05), while the overexpression of ESR1 in ER-negative MDA-MB-231 breast cancer cells inhibited cell death ( t = 4.16, 7.48, P < 0.05). Compared to the control group, the treatment with chloroquine increased the number of formed colonies of ESR1 knockdown ZR75 cells ( t = 8.49, P < 0.05), and inhibiting autophagy could reduce the death of ZR75 cells caused by ESR1 silencing. Under the treatment with ionizing radiation, the overexpression of ESR1 in MDA-MB-231 cells promoted protective autophagy, which, however, was reduced after ESR1 knockdown in ZR75 cells. Furthermore, it was observed that the knockdown of ATG5 in ZR75 cells was associated with reduced autophagy and an increase in cell death ( t = 4.19, 6.39, P < 0.05). In contrast, the overexpression of ATG5 in ZR75 cells reversed the increase in cell death caused by ESR1 knockdown ( t = 1.70, 4.65, P < 0.05). After the treatment of ER-positive ZR75 breast cancer cells with TAM, the expressions of ATG5 and ATG12 decreased, suggesting inhibited autophagy and an increase in cell death ( t = 18.70, P < 0.05). Furthermore, these processes were promoted by ionizing radiation ( t = 16.82, P < 0.05). Conclusions:The estrogen receptor encoded by ESR1 promotes protective autophagy of ER-positive breast cancer cells by increasing ATG5, further leading to radiation resistance in ER-positive breast cancer cells. Treatment with tamoxifen combined with ionizing radiation can increase the radiation sensitivity of ER-positive breast cancer cells.

Objective To explore abnormal microstmctural changes of white matter in patients with white matter lesions using diffusion tensor imaging(DTI),and to determine the association of such abnormalities of DTI parameters with cognitive function.Methods The objects who have already confirmed with WML were collected from March 2012 to February 2018 through magnetic resonance imaging (MRI) scan from the neurology department of Beijing Tiantan Hospital.Use The hamilton depression scale(HAMD) and the hamilton anxiety scale (HAMA) to eliminate anxiety and depression,and divided into WML-CN group,WML-VCIND group and WML-VAD group with Mini-mental state examination (MMSE),Montreal Cognitive Assessment (MOCA)and clinical dementia rating(CDR).In addition,select the healthy elderly people without WML by MRI scan as the normal control group.All of the subjects were detected with the superconduct magnetic resonance imaging system (German SIEMENS 3.0T) for the DTI scanning.Original images were processed with VBA.Then explore the changes of FA and MD of DTI in whole brain and regions of interest in NC group,WML-CN group,WML-VCIND group and WWML-VAD group,and its correlation with the severity of cognitive impairment in patients with WML.Results The damage degree of the fiber microstructure of brain white matter was significantly correlated with the total grade point of MoCA (P＜0.01).In figure FA,the variance analysis of F test results showed that the significant brain areas were the splenium of the corpus callosum,the genu of corpus callosum,bilateral posterior internal capsule,retrolenticular part of internal capsule,anterior thalamic radiation,partial inferior longitudinal fasciculus and inferior fronto-occipital fasciculus,cingulate,external capsule,upper and posterior part of the radiation crowns,partial superior longitudinal fasciculus,etc.(P＜0.05 after FWE correction based on TFCE method).In Figure MD,the variance analysis of F test results showed that the statistically significant brain areas mainly included the left external capsule and hook,partial genu and splenium of corpus callosum,Bilateral,bilateral inferior fronto-occipital fasciculus,inferior longitudinal fasciculus,anterior thalamic radiation,retrolenticular part of internal capsule,cingulate,etc (P＜ 0.05 after FWE conection based on TFCE).Conclusion No matter whether cognitive impairment exists in patient with WML or not,all DTI parameters are different from those of normal people.The integrity of white matter fiber has been damaged with different degrees.The more severe the cognitive impairment in the external manifestations of patients with WML,the greater the damage to the intrinsic white matter microstructure.

Objective:To explore abnormal microstructural changes of white matter in patients with white matter lesions(WML) using diffusion tensor imaging(DTI), and to determine the association of such abnormalities of DTI parameters with executive function.Methods:Totally 34 patients with WML were recruited from the department of Neurology, Beijing Tiantan Hospital, Capital Medical University from March 2012 to May 2019.All patients with WML were scored with Hamilton depression scale (HAMD) and Hamilton anxiety scale (HAMA), and assessed with Montreal cognitive assessment (MoCA) and clinical dementia rating(CDR). They were divided into WML-cognitive normal group, WML-vascular cognitive impairment-non dementia group and WML-Dementia group.The Stroop color and word test (SCWT), trail making test-A (TMTA), digit symbol test and verbal fluency test were carried out to evaluate executive function.In addition, the healthy elderly without WML lesions were selected as the control group after they were examined by MRI, and all brains of the subjects went through DTI with Siemens 3.0 T MR.The data were collected and analyzed by voxel based analysis (VBA). The anisotropy and mean diffusion coefficient of DTI in the region of interest (ROI) and other regions in the brain were studied in the four groups, and their correlation with scores of executive function in WML patients was analyzed.Results:(1)In these executive function test, there were significant differences between the patients with cognitive impairment (WML-VAD group, WML-VCIND group) and normal cognition group(WML-CN group, NC group), such as SCWT(B)(65.54±6.24 vs 43.67±0.95, 76.75±2.13 vs 43.67±0. 95, 65.54±6.24 vs 43.66±1.81, 76.75±2.13 vs 43.66±1.81), SCWT(C)(88.58±6.76 vs 61.63±1.31, 96.37±1.47 vs 61 63±1.31, 88.58±6.76 vs 66.31±8.19, 96.37±1.47 vs 66.31±8.19), TMTA(40.47±2.76 vs 30.92±0.47, 44.24±1.43 vs 30.92±0.47, 44.24±1.43 vs 31.99±2.07, 40.47±2.76 vs 31.99±2.07), TMTB(88.66±6.55 vs 80.34±0.61, 96.70±1.72 vs 80.34±0.61, 88.66±6.55 vs 83.10±5.91, 96.70±1.72 vs 83. 10±5.91), Digit Symbol Test(39.25±5.63 vs 47.00±2.55, 31.27±3.93 vs 47.00±2.5, 39.25±5.63 vs 48.86±4.34, 31.27±3.93 vs 48.86±4.34) and Verbal Fluency Test(8.94±1.00 vs 11.71±0.47, 6.64±0.81 vs 11.71±0.47, 8.94±1.00 vs 10.86±0.69, 6.64±0.81 vs 10.86±0.69) scores ( P<0.05); In the patients with cognitive impairment, there were significant differences between WML-VAD group and WML-VCIND group, such as SCWT(B), SCWT(C), TMTA, TMTB, digit symbol test and verbal fluency test scores ( P<0.05); There were significant differences between WML-CN patients and NC group in the scores of SCWT (C), verbal fluency test( P<0.05). (2)FA values in the genu of corpus callosum and the inferior longitudinal fasciculus were negatively correlated with the time of SCWT (B), SCWT (C) and the TMTA( r=-0.436--0.471), but positively correlated with the scores of digit symbol test and verbal fluency test( r=0.428-0.573). MD values in the genu of corpus callosum, the superior/inferior longitudinal fasciculus and the inferior fronto-occipital fasciculus were positively correlated with the time of SCWT (B), SCWT (C) and TMTA( r=0.432~0.609), but negatively correlated with the scores of digit symbol test and verbal fluency test( r=-0.424--0.630, all P<0.003125 after emendation). Conclusion:The executive function of patients with WML-Dementia decreases significantly.The more serious the damage of white matter microstructure, the more serious the damage of executive of function.

Acute lung injury (ALI) is a prevalent and severe clinical condition characterized by inflammatory damage to the lung endothelial and epithelial barriers, resulting in high incidence and mortality rates. Currently, there is a lack of safe and effective drugs for the treatment of ALI. In a previous clinical study, we observed that Jinyinqingre oral liquid (JYQR), a Traditional Chinese Medicine formulation prepared by the Taihe Hospital, Affiliated Hospital of Hubei University of Medicine, exhibited notable efficacy in treating inflammation-related hepatitis and cholecystitis in clinical settings. However, the potential role of JYQR in ALI/acute respiratory distress syndrome (ARDS) and its anti-inflammatory mechanism remains unexplored. Thus, the present study aimed to investigate the therapeutic effects and underlying molecular mechanisms of JYQR in ALI using a mouse model of lipopolysaccharide (LPS)-induced ALI and an in vitro RAW264.7 cell model. JYQR yielded substantial improvements in LPS-induced histological alterations in lung tissues. Additionally, JYQR administration led to a noteworthy reduction in total protein levels within the BALF, a decrease in MPAP, and attenuation of pleural thickness. These findings collectively highlight the remarkable efficacy of JYQR in mitigating the deleterious effects of LPS-induced ALI. Mechanistic investigations revealed that JYQR pretreatment significantly inhibited NF-κB activation and downregulated the expressions of the downstream proteins, namely NLRP3 and GSDMD, as well as proinflammatory cytokine levels in mice and RAW2647 cells. Consequently, JYQR alleviated LPS-induced ALI by inhibiting the NF-κB/NLRP3/GSDMD pathway. JYQR exerts a protective effect against LPS-induced ALI in mice, and its mechanism of action involves the downregulation of the NF-κB/NLRP3/GSDMD inflammatory pathway.
