Objective: The aim of this study is to evaluate the impact of glucose-6- phosphate dehydrogenase deficiency in Chinese on the intracellular glucose-6-phosphate dehydrogenase activity and reactive oxygen intermediates production of peripheral neutrophil. Methods: Glucose-6-phosphate dehydrogenase, its mRNA expression and reactive oxygen intermediates production(NBT test) in silent or stimulated neutrophil from health controls and patients with glucose-6-phosphate dehydrogenase deficiency were analysized. Results: Compared with health controls, the activities of glucose-6-phosphate dehydrogenase of peripheral neutrophil from patients with glucose-6 -phosphate dehydrogenase deficiency was decreased, and its mRNA expression increased. Reactive oxygen intermediate production increased(no statistical signification) in silence but decreased following stimulation by LPS in neutrophil from normal individuals than that from patients. Conclusion: Decreased activity of G-6-PD and production of reactive oxygen intermediates following stimulation in neutrophil could be caused by G-6-PD deficiency in Chinese.

We evaluated the differential expression and function of chitinase 3‐like‐1 in macrophage stimulated by Sporothrix schenckii and Candida albicans fungicidal ability of macrophage after stimulation with Sporothrix schenckii and Candida albi‐cans separately was detected .The expression of CHI3L1 gene in macrophage stimulated by Sporothrix Schenckii and Candida albicans was evaluated with real‐time PCR .The function of CHI3L1 protein in macrophages against the reproduction of Sporo‐thrix schenckii and Candida albicans was detected in vitro .Results showed that macrophages could engulf and kill Sporothrix Schenckii and Candida albicans in vitro .The expression of CHI3L1 gene in macrophage stimulated by Candida albicans was increased obviously .At the same time ,CHI3L1 protein can damper the reproduction of Candida albicans .However ,the ex‐pression of CHI3L1 gene was not elevated when macrophage was stimulated by Sporothrix schenckii and CHI3L1 protein played little role in reproduction of Sporothrix schenckii .The expression of CHI3L1 gene in macrophage was elevated after stimulation with Candida albicans ,but was not elevated with Sporothrix Schenckii .In correspondence with differential ex‐pression ,CHI3L1 in macrophages could impair the reproduction of Candida albicans but had a weak function on Sporothrix schenckii which might contribute to the pathogenesis of spo‐rotricosis .

Objective:To explore the clinical characteristics and prognostic risk factors of accidental injuries in pediatric intensive care unit(PICU).Methods:The children with accidental injuries admitted to the PICU at Shanghai Children′s Hospital from January 2017 to December 2019 were analyzed retrospectively.The patients were divided into survival group and death group according to outcome.We collected the patients′ clinical data and laboratory indexes, and analyzed the differences between two groups.Multivariate Logistic regression was used to screen the risk factors of death and receiver-operating characteristic(ROC)curve was used to determine the threshold.Results:(1)A total of 253 children were included, accounting for 5.2% of PICU hospitalization during the same period.There were 137 males(54.2%)and 116 females(45.8%), with an average age of 45(19, 96)months.The top three causes of accidental injuries were fall injury in 82 cases(32.4%), traffic accident in 70 cases(27.7%)and foreign body in 39 cases(15.4%). There were 22 cases of deaths, with a fatality rate of 8.7%.(2)The mean arterial pressure at admission in the death group was lower than that in the survival group( P<0.05), and the total length of stay was longer( P<0.001). There were significant differences in Glasgow coma scale, Pediatric Risk of Mortality Scoring Ⅲ(PRISM Ⅲ)between the two groups( P<0.001). In the death group, and the blood lactic acid(LA) significantly increased( P<0.001), hemoglobin and fibrinogen were lower than those in the survival group, the activated partial thromboplastin time and prothrombin time(PT)were significantly prolonged( P<0.001). (3)Multivariate Logistic regression analysis showed that PRISM Ⅲ score, LA and PT were independent risk factors for the death of accidental injuries.The area under curve(AUC)of PRISM Ⅲ score was 0.987(95% CI 0.976-0.999, P<0.001)and the cut-off value was 11 with a sensitivity of 100% and a specificity of 95.7%.The AUC of LA was 0.886(95% CI 0.810-0.961, P<0.001)and the cut-off value was 3.1 mmol/L with a sensitivity of 85.7% and a specificity of 77.3%.The AUC of PT was 0.835(95% CI 0.730-0.941, P<0.001)and the cut-off value was 13.9 s with a sensitivity of 86.6% and a specificity of 72.7%. Conclusion:The main accidental injuries in PICU of our hospital in the past three years are falling injuries, traffic accidents and foreign body injuries.PRISM Ⅲ score, LA and PT at admission are independent risk factors for predicting death.

AMP-activated protein kinase(AMPK)is a conserved cellular energy receptor that plays an important role in regulating cell growth,proliferation,differentiation,autophagy,phosphorylation,crosstalk,and glucose and lipid metabolism.AMPK is activated during low-energy or other extreme conditions,and it is suppressed by an excess of nutrients to maintain the energy balance.Additionally,the regulatory mechanism of the AMPK signaling pathway mediating ferroptosis reflects its unique role.AMPK plays a specialized regulatory function in various organelles,which provides a new direction for disease therapy.It is also a therapeutic target to prevent diseases such as reproductive system diseases,aging,cancer,inflammation and cardiac dysfunction.This article reviews cellular energy imbalance.AMPK stimulates its potential therapeutic potential in diseases and drugs through diverse signal regulatory mechanisms.It provides a new treatment for different system diseases.This review summarizes the diverse regulatory mechanisms of the AMPK signaling pathway and provides a theoretical reference for cancer therapy and other disease therapies targeting AMPK.

Objective To explore the relationship between m6A RNA methylation regulators and prognosis of prostate cancer.Methods Clinicopathological and mRNA-related data of 496 cases of prostate cancer were downloaded from the Cancer Genome Atlas(TCGA)database,and 12 m6A regulators were identified:METTL3,METTL14,WTAP,RBM15,ZC3H13,YTHDC1,YTHDC2,YTHDF1,YTHDF2,HNRNPC,FTO,and ALKBH5.The m6A regulators differentially expressed in prostate cancer samples were screened.Unsupervised clustering of prostate cancer tissues was used to compare differences in overall survival.Multivariate Cox regres-sion analysis was used to divide patients into high-and low-risk groups according to the risk scores,and survival rates were compared.The risk score of clinicopathological factors was determined,and a multivariate Cox regression analysis model was constructed to evaluate the prognostic prediction value.Immunohistochemical staining was performed to detect METTL14 and FTO expression in prostate cancer tis-sues.Results Eight differentially expressed regulators were screened from 12 m6A regulators.Unsupervised cluster analysis divided the samples into Clusters 1,2,and 3 and found significant differences in survival time in all three groups.Multivariate Cox regression analyses revealed that METTL14and FTOwere strongly associated with the prognosis of patients with prostate cancer.A Cox regression model con-structed to score the risk of prostate cancer revealed that the high-and low-risk groups had survival differences,and the risk score could be used as an independent prognostic factor.The positive expression rates of METTL14 and FTO protein in prostate cancer tissues were significantly higher than those in adjacent tissues(P<0.05).Conclusion In this study,a prognostic prediction model based on m6A regulators of prostate cancer was constructed,in which the risk score could be used as an independent prognostic factor.METTL14and FTOcould be used as molecular markers for the diagnosis of prostate cancer and as potential targets for treatment.

Objective To explore the safety and efficacy of fusion imaging technique and traditional ultrasound guidance in percutaneous nephrolithotomy,and to compare the difference of two methods for PCNL.Methods Patients with renal calculus,who underwent percutaneous nephrolithotomy from January 2016 to August 2016,were enrolled in the study.The patients were randomly divided into two groups by SAS software.The control group was treated with traditional ultrasound guided puncture technique (Ultrasound group).Experimental group was treated with fusion imaging method (CT-US group).Preoperative patient CT image data was uploaded to the image fusion ultrasound machine for data synchronization.Both groups used the same way to establish a standard channel (F24).Lithoclast system from EMS was used to remove stones.Intraoperative parameters (time to define the target calyx,access establishment time,operative duration) and postoperative perioperative data (estimated blood loss,stone-free rate,severe complications) were compared between the two groups.Results 65 cases of patients were enrolled into the study.There was no significant difference in age (P =0.72),body mass index (P =0.78),stone size (P =0.53) and so on.Compared with the control group,the time duration to define the target calyx in CT-US group is significantly decreased in experiment group(50.4 ± 18.1) s vs.(82.1 ± 37.7) s,(P =0.02).The time to establish the access and fulfill the procedure shows no significant difference between the two groups,respectvely(P =0.45,0.61).Also,significant differences can be found in the hemoglobin loss during and after the surgery(1.1 ± 0.5) g/L vs.(1.4 ± 0.4) g/L (P =0.04).The difference in severe complications (Clavien Ⅲ and above),stone-free rate (P =0.60) and transfusion rate (P =1.00) was not significant.Conclusions Our primary study shows CT-altrasound image fusion guide PCNL is a safe and reliable technology.The time duration to define the target calyx was decreased compared with traditional US guidance method.The target calyx chosen was more accurate,with lower blood loss during the perioperative period.

Cerebrovascular disease is one of the main diseases that threaten human health and life,and the age of onset become younger and younger. Research shows that Toll-like receptors (TLRs) express in brain, have effects on neurons, play an important role in the occurrence and development of cerebral ischemia and secondary cerebral injury.It is clear that TLR2, TLR3, TLR4, TLR7 and TLR9 have influence on occurrence and development of cerebral ischemia. This is crucial for understanding the relationship between immune inflammation and nerve regeneration, and improving clinical treatment.

ObjectiveTo explore the influencing factors of anticipatory grief among family caregivers of terminal-stage cancer patients，and provide a reference for formulating intervention programs for anticipatory grief. MethodsAn interview outline was designed，and the descriptive qualitative research method was used.The aim was to select 11 family narrative caregivers of patients in the Department of Medical Oncology，Nanfang Hospital，Southern Medical University for semi-structured in-depth interviews.Based on the social ecology model，using the narrative theory of life and health as the framework，the content analysis method was adopted to analyze the data. ResultsA total of 3 themes and 12 sub-themes were extracted，including the influencing factors at the individual level （narrative literacy，cognitive level towards death，and sense of self-worth），the influencing factors at the interpersonal level （patient’s disease situation，education level，economic status，family narrative connection，peer narrative connection，and narrative connection between doctors and family members），and the influencing factors at the cultural policy level （social culture，physical environment of the ward，and policy level）. ConclusionAnticipatory grief was affected by multiple factors，and multi-dimensional narrative connection should be constructed from individual，interpersonal，family，social，and other levels to prevent caregivers from falling into a narrative lock of single caregiver identity，alleviate the impact of anticipatory grief on caregivers，and improve their quality of life.
