ABSTRACT
OBJECTIVES@#To classify bladder cancer based on immune cell infiltration score and to construct a risk assessment model for prognosis of patients.@*METHODS@#The transcriptome data and data of breast cancer patients were obtained from the TCGA database. The single sample gene set enrichment analysis was used to calculate the infiltration scores of 16 immune cells. The classification of breast cancer patients was realized by unsupervised clustering, and the sensitivity of patients with different types to immunotherapy and chemotherapy was analyzed. The key modules significantly related to the infiltration of key immune cells were identified by weighted correlation network analysis (WGCNA), and the key genes in the modules were extracted. A risk scoring model and a nomogram for risk assessment of prognosis for bladder cancer patients were constructed and verified.@*RESULTS@#The immune cell infiltration scores of normal tissues and tumor tissues were calculated, and B cells, mast cells, neutrophils, T helper cells and tumor infiltrating lymphocytes were determined to be the key immune cells of bladder cancer. Breast cancer patients were clustered into two groups (Cluster 1 and Custer 2) based on immune cell infiltration scores. Compared with patients with Cluster 1, patients with Cluster 2 were more likely to benefit from immunotherapy (P<0.05), and patients with Cluster 2 were more sensitive to Enbeaten, Docetaxel, Cyclopamine, and Akadixin (P<0.05). WGCNA screened out 35 genes related to key immune cells, and 4 genes (GPR171, HOXB3, HOXB5 and HOXB6) related to the prognosis of bladder cancer were further screened by LASSO Cox regression. The areas under the ROC curve (AUC) of the bladder cancer prognosis risk scoring model based on these 4 genes to predict the 1-, 3- and 5-year survival of patients were 0.735, 0.765 and 0.799, respectively. The nomogram constructed by combining risk score and clinical parameters has high accuracy in predicting the 1-, 3-, and 5-year overall survival of bladder cancer patients.@*CONCLUSIONS@#According to the immune cell infiltration score, bladder cancer patients can be classified. And the bladder cancer prognosis risk scoring model and nomogram based on key immune cell-related genes have high accuracy in predicting the prognosis of bladder cancer patients.
ABSTRACT
OBJECTIVES@#To construct a prediction model for the prognosis of bladder cancer patients based on the expression of ion channel-related genes (ICRGs).@*METHODS@#ICRGs were obtained from the existing researches. The clinical information and the expression of ICRGs mRNA in breast cancer patients were obtained from the Cancer Genome Atlas database. Cox regression analysis, minimum absolute shrinkage and selection operator regression analysis were used to screen breast cancer prognosis related genes, which were verified by immunohistochemistry and qRT-PCR. The risk scoring equation for predicting the prognosis of patients with bladder cancer was constructed, and the patients were divided into high-risk group and low-risk group according to the median risk score. Immune cell infiltration was compared between the two groups. Kaplan-Meier survival curve and receiver operating characteristic (ROC) curve were used to evaluate the accuracy and clinical application value of the risk scoring equation. The factors related to the prognosis of bladder cancer patients were analyzed by univariate and multivariate Cox regression, and a nomogram for predicting the prognosis of bladder cancer patients was constructed.@*RESULTS@#By comparing the expression levels of ICRGs in bladder cancer tissues and normal bladder tissues, 73 differentially expressed ICRGs were dentified, of which 11 were related to the prognosis of bladder cancer patients. Kaplan-Meier survival curve suggested that the risk score based on these 11 genes was negatively correlated with the prognosis of patients. The area under the ROC curve of the risk score for predicting the prognosis of patients at 1, 3 and 5 year was 0.634, 0.665 and 0.712, respectively. Stratified analysis showed that the ICRGs-based risk score performed well in predicting the prognosis of patients with American Joint Committee on Cancer (AJCC) stage Ⅲ-Ⅳ bladder cancer (P<0.05), while it had a poor value in predicting the prognosis of patients with AJCC stage Ⅰ-Ⅱ (P>0.05). There were significant differences in the infiltration of plasma cells, activated natural killer cells, resting mast cells and M2 macrophages between the high-risk group and the low-risk group. Cox regression analysis showed that risk score, smoking, age and AJCC stage were independently associated with the prognosis of patients with bladder cancer (P<0.05). The nomogram constructed by combining risk score and clinical parameters has high accuracy in predicting the 1, 3 and 5 year overall survival rate of bladder cancer patients.@*CONCLUSIONS@#The study shows the potential value of ICRGs in the prognostic risk assessment of bladder cancer patients. The constructed prognostic nomogram based on ICRGs risk score has high accuracy in predicting the prognosis of bladder cancer patients.

In recent years, researchers have found that patients with nonalcoholic fatty liver disease (NAFLD) often have urolithiasis, and the incidence of urolithiasis increases gradually with the severity of NAFLD. Meanwhile, the detection rate of NAFLD was higher in patients with urolithiasis than in normal controls. In this paper, we reviewed the domestic and international studies on the correlation between urolithiasis and NAFLD and described the related pathogenesis, such as insulin resistance, oxidative stress, abnormal lipid metabolism and impaired glyoxalate detoxification. Meanwhile, this paper proposed preventive measures to reduce the risk of development and recurrence of NAFLD-associated urolithiasis by addressing the common risk factors of both diseases, including metabolism-related diseases, lifestyle and diet.
ABSTRACT
Objective:To explore the potential mechanisms of anterior cingulate cortex (ACC) in modulating pain behavior and anxiety-like behavior of rats with chronic non-specific low back pain induced by nerve growth factor (NGF).Methods:Ninety-six male SPF grade SD rats aged 8 weeks were randomly divided into four groups according the random number table method: control group, model group, control+ D-2-amino-5-phosphonopentanoate (D-AP5) group (control+ D-AP5 group) and model+ D-AP5 group, with 24 rats in each group.Low back pain model of rat was established by injection of NGF into multifidus muscle (left side) of the low backs of rats(two times with a five-day interval). Five days after modeling, rats in model+ D-AP5 group and control+ D-AP5 group were injected with the N-methyl-D-aspartate (NMDA) receptor antagonist D-AP5(2 μg, 0.3 μL) at the right side of the ACC once a day for consecutive 3 days, and rats in control group and model group were injected with the same amount of 0.9% sodium chloride solution. Seven days after modeling, the pain threshold of rats was evaluated by mechanical stimulation test and hot and cold plate test.The anxiety-like behavior was tested by open field test.The density of glial fibrillary acidic protein (GFAP) positive cells and c-Fos(a kind of immediate early gene) positive cells of the spinal cord were observed by immunofluorescence. The expression of GFAP, c-Fos, phosphorylated-c-Jun N-terminal kinases (p-JNK), monocyte chemoattractant protein-1 (MCP-1), and chemokine (C-X-C motif) ligand 1 (CXCL-1) proteins in the L2 segment of the spinal cord were detected by Western blot. SPSS 23.0 software was used for statistical analysis. One-way ANOVA was used to analyze normal distribution measurement data for comparison among multiple groups, and Tukey test was used for further pairwise comparisons. The Kruakal-Wallis H test was used for non-normal distribution measurement data, and Mann-Whitney U test was used for further pairwise comparisons with Bonferroni-corrected P-values. Results:In the experiments measuring pressure pain threshold (PPT) and paw withdrawal threshold (PWT), there were statistically significant differences in the PPT and PWT of rats among the four groups ( F=53.498, 41.939, both P<0.001). Seven days after modeling, PPT ((418.5±46.9) g) and PWT ( (55.6±7.1) g) in the ipsilateral side of the rats in model+ D-AP5 group were higher than those in model group ((290.0±32.0) g, (30.5±7.5) g) (both P<0.001). In the open field test, there were statistically significant differences in percentage of the inner zone distance ( H=11.922, P<0.01) and the percentage of inner zone time ( H=21.614, P<0.001) of rats among the four groups. The percentage of inner zone time in model+ D-AP5 group was higher than that in model group (5.6(4.3, 7.9) %, 3.1(2.1, 3.8) %) ( P<0.01). The results of immunofluorescence showed that there were statistically significant differences in the density of GFAP positive cells and c-Fos positive cells at the ipsilateral side of the superficial laminae of rats among the four groups ( H=49.085, F=18.120, both P<0.001). The density of GFAP positive cells (34.3(21.1, 47.5) cells/mm 2) and c-Fos positive cells ((52.7±39.4) cells/mm 2) at the ipsilateral side of the superficial laminae in model+ D-AP5 group were less than those in model group (76.5(68.6, 94.9) cells/mm 2, (112.4±63.7) cells/mm 2) (both P<0.001). The Western blot results showed that there were statistically significant differences in the protein expression of GFAP, c-Fos, p-JNK, MCP-1 and CXCL-1 in the L2 segment of rats among the four groups ( F=49.413, 38.437, 41.867, 36.735, 130.951, all P<0.001). The protein expression of GFAP (1.7±0.5), c-Fos (1.1±0.1), p-JNK (1.7±0.3), MCP-1 (1.0±0.4) and CXCL-1 (0.8±0.1) in the L2 segment in model+ D-AP5 group were lower than those in model group ((4.3±0.7), (2.6±0.5), (2.8±0.4), (2.9±0.4), (3.5±0.4)) (all P<0.01). Conclusion:ACC modulates mechanical hyperalgesia and anxiety-like behavior in chronic non-specific low back pain rats, which might be associated with the involvement of spinal astrocytes, p-JNK signal pathway and chemokines such as MCP-1 and CXCL-1.
ABSTRACT
Sepsis is currently the leading cause of death in the intensive care unit, and its survivors also experience long-term immunosuppression and high rates of recurrent infections. At present, the clinical treatment of sepsis is still based on antibiotics, intravenous rehydration, and vasopressors, and there is no targeted drug treatment. However, as the rate of antibiotic resistance continues to increase, immunotherapy is highly anticipated as a new treatment. Patients with sepsis are often accompanied by acute leukocyte immune dysfunction and immunosuppression, which may be an important risk factor for the increasing morbidity and mortality of patients. Targeted inhibition of specific cell surface inhibitory immune checkpoint receptors and ligands, such as programmed death receptor-1 (PD-1), programmed death-ligand 1 (PD-L1), and other targets, can improve the host’s resistance to infection. In this paper, the research progress of PD-1 and PD-L1 in the immune response to sepsis was summarized to provide a theoretical basis for their further application in the treatment of sepsis in the future.
ABSTRACT
As central players in cellular structure and function, proteins have long been central themes in life science research. Analyzing the impact of protein sequence variation on its structure and function is one of the important means to study proteins. In recent years, a technology called deep mutational scanning (DMS) has been widely used in the field of protein research. It introduces thousands of mutations in parallel in specific regions of proteins through high-abundance DNA libraries. After screening, high-throughput sequencing is employed to score each mutation, revealing sequence-function correlations. Due to its high-throughput, fast and easy, and labor-saving features, DMS has become an important method for protein function research and protein engineering. This review briefly summarizes the principle of DMS technology, highlighting its applications in mammalian cells. Moreover, this review analyzes the current technical bottlenecks, aiming to facilitate relevant research.

Objective@#This study aimed to evaluate the zygomaticotemporal suture (ZTS) maturation, analyze the age distribution patterns of ZTS maturation stages, and investigate the relationship between ZTS and cervical vertebral maturation (CVM). @*Methods@#A total of 261 patients who underwent cone-beam computed tomography (112 males, mean age, 13.1 ± 3.3 years; 149 females, mean age, 13.7 ± 3.1 years) were examined to evaluate the ZTS stages. The ZTS stages were defined based on a modified method from previous studies on zygomaticomaxillary sutures. Differences between groups and correlations between indicators were analyzed using the Spearman correlation test, intraclass coefficient of correlation (ICC), one-way analysis of variance and rank sum test.Statistical significance was set at p 10 were found for several cervical stages (CSs), including CS1 and CS2 for the diagnosis of stage B, CS1 to CS3 for the diagnosis of stages B and C, and CS6 for the diagnosis of stages D and E. @*Conclusions@#The ZTS maturation stage may be more relevant to the CVM stage than to the chronological age. The CVM stages can be good indicators for clinical decisions regarding maxillary protraction, except for CS4 and CS5.
ABSTRACT
Hepatic ischemia/reperfusion injury (HIRI) is a serious complication that occurs following shock and/or liver surgery. Gut microbiota and their metabolites are key upstream modulators of development of liver injury. Herein, we investigated the potential contribution of gut microbes to HIRI. Ischemia/reperfusion surgery was performed to establish a murine model of HIRI. 16S rRNA gene sequencing and metabolomics were used for microbial analysis. Transcriptomics and proteomics analysis were employed to study the host cell responses. Our results establish HIRI was significantly increased when surgery occurred in the evening (ZT12, 20:00) when compared with the morning (ZT0, 08:00); however, antibiotic pretreatment reduced this diurnal variation. The abundance of a microbial metabolite 3,4-dihydroxyphenylpropionic acid was significantly higher in ZT0 when compared with ZT12 in the gut and this compound significantly protected mice against HIRI. Furthermore, 3,4-dihydroxyphenylpropionic acid suppressed the macrophage pro-inflammatory response in vivo and in vitro. This metabolite inhibits histone deacetylase activity by reducing its phosphorylation. Histone deacetylase inhibition suppressed macrophage pro-inflammatory activation and diminished the diurnal variation of HIRI. Our findings revealed a novel protective microbial metabolite against HIRI in mice. The potential underlying mechanism was at least in part, via 3,4-dihydroxyphenylpropionic acid-dependent immune regulation and histone deacetylase (HDAC) inhibition in macrophages.
ABSTRACT
Extracorporeal membrane oxygenation (ECMO), as an effecitive life support technique, is widely used in patients with respiratory and/or cardiac failure. Infection, with a prevalence of approximately 21% in adult patients with ECMO, is one of the most common complications and has a significant impact on mortality. Early identification of infections, and accurate prevention and anti-infective therapies for ECMO patients can improve their survival, but there is a lack of standardized protocols for recognition, diagnosis, management, prevention and treatment of the infections. By analyzing a series of literatures on healthcare-associated infections in patients with ECMO, the epidemiology, pathogens, risk factors, diagnosis, prevention and treatment were summarized to provide a theoretical background for the early identification, diagnosis and patient management of nosocomial infections.

ABSTRACT
Objective:To analyze the effects of the combined applications of Omalizumab and subcutaneous immunotherapy (SCIT) in improving clinical symptoms and immunotherapy tolerance in children with allergic asthma.Methods:A total of 9 children with asthma who received Omalizumab combined with SCIT in the Pediatrics Asthma Clinic of the Second Hospital of Tianjin Medical University from July 2018 to August 2020 were retrospectively analyzed.The symptoms of asthma, lung function, exhaled nitric oxide(FeNO), life quality scores, inhaled corticosteroids (ICS) dosage, comorbidities improvement, and adverse reactions during SCIT were analyzed and compared before and after the combined treatment.Results:After treatment, both the scores of children asthma control test/asthma control test (C-ACT/ACT) and pediatric asthma quality of life questionnaire (PAQLQ) improved in 9 patients with reduced or maintained doses of ICS.After treatment, comorbidities, including rhinitis and eczema, the scores of visual analogue scale (VAS) for rhinitis, pediatric rhinoconjunctivitis quality of life questionnaire(PRQLQ) and scoring atopic dermatitis (SCORAD) were all improved.During SCIT, all children didn′t have systemic adverse reactions, and 4 children had 1 (2 cases), 3 (1 case), and 8 (1 case) local adverse reactions, respectively.The number of rapid local adverse reactions accounts for only 2.6% (3/116 times), and the number of delayed local adverse reactions occupies 8.6% (10/116 times). Among them, the number of local adverse reactions accounts for only 2.6 % (3/116 times), and the dia-meters of swelling or induration were more than 4 cm.Conclusions:The combined applications of anti-IgE therapy and SCIT can effectively improve the symptoms and quality of life, and reduce asthma exacerbations and dosage of ICS in children with asthma.It also has certain effects on the improvement of comorbidities.At the same time, the addition of anti-IgE therapy can enhance the tolerance and compliance of SCIT.
ABSTRACT
Objective:To gain insight into the constitution of juvenile rheumatic diseases, treatment outcome and trends of rheumatic inpatients in past 12 years, and to improve awareness of juvenile rheumatic diseases.Methods:The clinical data of 5 950 patients in rheumatology department of the affiliated pediatric hospital of Fudan University (from 2005 to 2016) were analyzed retrospectively, and the chi-square test was used to compare and analyze the incidence.Results:Disease changes: ① The top three rheumatic diseases were Kawasaki disease (KD) (44.3%), Henoch-schoniein purpura (HSP) (35.4%), juvenile idiopathic arthritis (JIA)(9.6%). ② The number of all constitution of juvenile rheumatic diseases in hospital increased other than HSP. ③ The rheumatic diseases were increased from 17 to 37 kinds in the past 6 years. ④ The number of systemic lupus erythematosus (SLE) increased year by year (112/2 348 vs 197/3 602, χ2=1.41, P=0.235), as well as the severe SLE (35/112 vs 55/197, χ2=0.38, P=0.536). ⑤ The rate of rheumatic diseases complicated with macrophage activation (MAS) was 7.2‰(43/5 950). 12.9%(26/201) of systemic juvenile idiopathic arthritis(sJIA) were complicated with MAS, which was accounted for 60.5%(26/43) of total number of MAS in rheumatic diseases. In the last 6 years, there was a significant increase in the number of patients with MAS in patients with rheumatic diseases ( χ2=14.1, P<0.01) and sJIA( χ2=11.2, P<0.01). ⑥ 1.1%(64/5 950) of rheumatic diseases patients had lung lesions, juvenile dermatomyositis (JDM) accounted for 24.4%(20/82). In the last 6 years, the number of patients with lung lesions associated with rheumatic diseases increased significantly ( χ2=5.66, P=0.017). ⑦ The mortality rate of juvenile rheumatic diseases was only 3.7‰(22/5 950), and 45.5% occurred in SLE (10/22). The mortality rate of SLE decreased in last 6 years (5/112 vs 5/197, χ2=0.34, P=0.558). Conclusion:The constitution of juvenile rheumatic diseases in our center is decreasing for systemic vasculitis (KD, HSP), JIA, SLE, JDM in last 6 years. The annual total number of patients is relatively stable. But rare, difficult and critically illed cases increase year by year. Although SLE is still the primary cause of death in juvenile rheumatic diseases in recent 6 years, the mortality rate has decreased year by year.

ABSTRACT
Objective@#To compare the value of MRI total burden and diffusion tensor tract-based spatial statistics (TBSS) for identifying cognitive impairment in patients with cerebral small vascular disease (CSVD).@*Methods@#Consecutive patients with CSVD diagnosed in Suzhou Hospital Affiliated to Nanjing Medical University from January 2018 to June 2019 were enrolled. They were divided into cognitive impairment group and cognitive normal group. The MRI overall burden was evaluated, and TBSS analysis was performed to obtain regions with differences in diffusion parameters between the two groups. Multivariate logistic regression analysis was used to determine the independent risk factors for cognitive impairment. The receiver operating characteristic (ROC) curve was used to identify the recognition ability of the MRI overall burden and TBSS analysis for cognitive impairment in patients with CSVD.@*Results@#A total of 71 patients with CSVD were enrolled, including 41 (57.75%) in the cognitive impairment group and 30 (42.25%) in the cognitive normal group. There was a statistically significant difference in the proportion of patients with white matter hyperintensities between the two groups, but the MRI overall burden was not statistically significant difference. After adjusting for the confounding factors such as age and gender, multivariate logistic regression analysis showed that white matter hyperintensities was an independent risk factor for cognitive impairment in patients with CSVD (odds ratio 3.459, 95% confidence interval 1.196-10.007; P=0.022). Diffuse parameters of the white matter area, such as the genu of corpus callosum, anterior thalamic radiation, fasciculus longitudinalis superior, and frontal-occipital fasciculus in the cognitive impairment group were significantly different from those in the cognitive normal group (all P<0.05). The fractional anisotropy of left anterior thalamic radiation (r=0.252, P=0.036) and the radial diffusivity of the genu of corpus callosum (r=-0.246, P=0.042) were significantly correlated with cognitive scores. ROC analysis showed that the areas under the curve of the MRI total burden, the fractional anisotropy of left anterior thalamic radiation, and the radial diffusivity of the genu of corpus callosum for identifying cognitive impairment were 0.61, 0.56 and 0.57, respectively.@*Conclusion@#White matter hyperintensities is an independent risk factor for cognitive impairment in patients with CSVD. TBSS analysis may be superior to MRI overall burden assessment in the specific recognition of cognitive impairment in patients with CSVD. Some diffuse parameters have a certain correlation with the overall cognitive status, and may be used as early imaging markers for cognitive impairment in patients with CSVD.
