Objective:To construct a novel cuproptosis-related gene signature (CRGS) for prediction of prognosis, immunotherapy response and drug sensitivity in patients with hepatocellular carcinoma (HCC).Methods:Data materials for this study were obtained from the international cancer genome consortium (ICGC), the cancer genome atlas (TCGA) database and Migort210 database, and protein expression profiles were obtained from the human protein atlas image classification database. Based on the TCGA cohort, the least absolute shrinkage and selection operator algorithm was applied to construct the CRGS and calculate the risk score for each HCC patient. HCC patients were grouped according to the median risk score: HCC patients in the TCGA cohort were divided into a high-risk group TCGA and a low-risk group TCGA with 184 cases in each group; HCC patients in the ICGC cohort were divided into a high-risk group ICGC and a low-risk group ICGC with 116 cases in each group. Patients in the Migort210 cohort were divided into a responder group ( n=68) and a non-responder group ( n=230) based on their response to immunotherapy. We assessed the value of CRGS in predicting the prognosis of HCC patients in the TCGA cohort and validated whether CRGS could be used to predict the prognosis of HCC patients in the ICGC dataset. To explore the role of CRGS in predicting immunotherapy response and drug sensitivity in HCC patients based on data from the TCGA cohort, and to apply the Migort210 immunotherapy cohort to validate the clinical value of CRGS in predicting immunotherapy in malignant tumors. Results:CRGS consists of four copper death-related genes: GLS, CDKN2A, LIPT1, and DLAT. Patients in the high-risk group TCGA had lower overall survival (OS), disease-specifical survival, and progression-free interval than those in the low-risk group TCGA (all P<0.01). OS of patients in the high-risk group ICGC was lower than that in the low-risk group ICGC ( P=0.022). Multivariate Cox regression analysis showed that CRGS was an independent risk factor for poor prognosis in HCC patients (TCGA: HR=2.991, 95% CI: 1.781-5.049, P<0.001; ICGC: HR=4.621, 95% CI: 1.685-12.674, P=0.033). Risk scores were positively correlated with the expression levels of CTLA4, PDCD1, CD80 and HLLA2 (all P<0.001). Patients in the high-risk group TCGA had lower tumor immune dysfunction and rejection scores than those in the low-risk group TCGA [-0.04(-0.07, -0.02) vs. -0.02(-0.04, 0) points], and the difference was statistically significant ( P<0.001). Patients in the responder group had a higher risk score than the non-responder group [1.70 (1.56, 1.90) vs. 1.63 (1.52, 1.80)], with a statistically significant difference ( P<0.05). The half-inhibitory concentrations (IC 50) for sunitinib, rapamycin and etanercept were higher in the high-risk group TCGA than that in the low-risk group TCGA, while the IC 50 for erlotinib was lower than that in the low-risk group TCGA, and the differences were all statistically significant (all P<0.001). Conclusion:The CRGS might be served as a potential biomarker to predict the prognoses, immunotherapy response, and drug sensitivity of patients with HCC.

ObjectiveTo explore the guidance value of “treatment of disease in accordance with three conditions” theory in the prevention and treatment of corona virus disease 2019(COVID-19) based on the differences of syndromes and traditional Chinese medicine(TCM) treatments in COVID-19 patients from Xingtai Hospital of Chinese Medicine of Hebei province and Ruili Hospital of Chinese Medicine and Dai Medicine of Yunnan province and discuss its significance in the prevention and treatment of the unexpected acute infectious diseases. MethodDemographics data and clinical characteristics of COVID-19 patients from the two hospitals were collected retrospectively and analyzed by SPSS 18.0. The information on formulas was obtained from the hospital information system (HIS) of the two hospitals and analyzed by the big data intelligent processing and knowledge service system of Guangdong Hospital of Chinese Medicine for frequency statistics and association rules analysis. Heat map-hierarchical clustering analysis was used to explore the correlation between clinical characteristics and formulas. ResultA total of 175 patients with COVID-19 were included in this study. The 70 patients in Xingtai,dominated by young and middle-aged males,had clinical symptoms of fever, abnormal sweating,and fatigue. The main pathogenesis is stagnant cold-dampness in the exterior and impaired yin by depressed heat, with manifest cold, dampness, and deficiency syndromes. The therapeutic methods highlight relieving exterior syndrome and resolving dampness, accompanied by draining depressed heat. The core Chinese medicines used are Poria,Armeniacae Semen Amarum,Gypsum Fibrosum,Citri Reticulatae Pericarpium,and Pogostemonis Herba. By contrast,the 105 patients in Ruili, dominated by young females, had atypical clinical symptoms, and most of them were asymptomatic patients or mild cases. The main pathogenesis is dampness obstructing the lung and the stomach, with obvious dampness and heat syndromes. The therapeutic methods are mainly invigorating the spleen, resolving dampness, and dispersing Qi with light drugs. The core Chinese medicines used are Poria,Atractylodis Macrocephalae Rhizoma,Glycyrrhizae Radix et Rhizoma,Coicis Semen,Platycodonis Radix,Lonicerae Japonicae Flos, and Pogostemonis Herba. ConclusionThe differences in clinical characteristics, TCM syndromes, and medication of COVID-19 patients from the two places may result from different regions,population characteristics, and the time point of the COVID-19 outbreak. The “treatment of disease in accordance with three conditions” theory can help to understand the internal correlation and guide the treatments.

Objective:
To study the prevalence and correlates of diabetes among HIV/AIDS who were on antiretroviral therapy (ART) in Dehong Dai and Jingpo autonomous prefectures (Dehong), Yunnan province.
Methods:
The database of HIV/AIDS receiving ART in Dehong was downloaded by using the basic information system of AIDS prevention and control in China. In this cross-sectional study, HIV/AIDS patients who were currently on ART and aged 18 years or above, were consecutively recruited, between July 2017 and June 2018, in Dehong. All the subjects underwent hemoglobin A1c (HbA1c) testing. Patient with diabetes was defined as meeting any of these indicators (HbA1c ≥6.5%, baseline FPG ≥7.0 mmol/L, FPG ≥7.0 mmol/L in the most recent visit). Both univariate and multivariate logistic regression analysis were carried on to evaluate the correlates of diabetes among the HIV/AIDS patients.
Results:
In total of 4 376 HIV/AIDS patients were included for analysis, with the average age as (43.7±10.1) years, proportion of males as 53.8% (2 356/4 376) and the HCV positive rate as 24.1% (1 055/4 376). The mean years was (8.9±3.8) years after the HIV diagnosis was made, and the mean duration on treatment was (6.8±2.9) years. The prevalence of diabetes was 11.4% (500/4 376). Through multivariate logistic regression analysis, data showed that the risk factors of diabetes of HIV/AIDS on ART were: aged 40 years or above, being male, HCV positive, baseline body mass index ≥24.0 kg/m2, elevated TG ≥1.70 mmol/L in the most recent visit and baseline antiretroviral regimens under Efavirenz (EFV).
Conclusions
Prevalence rate of diabetes appeared higher in HIV/AIDS patients who were on ART in Dehong. Prevention and control measures should be targeted on HIV/AIDS patients who were with risk factors of diabetes as being elderly, male, HCV positive, overweight and higher TG. Further esearch is needed to evaluate the association between the use of EFV and diabetes.

ObjectiveTo evaluate the efficacy and safety of An'erning granules in the treatment of community-acquired pneumonia in children. MethodA randomized, double-blind, single-simulation, placebo-controlled trial was designed in this study. The children were randomly assigned into an observation group (An'erning granules combined with ceftriaxone sodium) and a control group (An'erning granules placebo combined with ceftriaxone sodium) according to the ratio of 2∶1. The disease cure rate was taken as the main indicator of efficacy, and the safety of An'erning granules was observed. ResultA total of 206 children (137 in the observation group and 69 in the control group) were included in this study. Before treatment, the age, sex, body height, body weight, diagnosis time of pneumonia, and symptom and sign scores had no significant differences between the two groups. After 8 days of continuous medication, the observation group[70.80%(97/137)] had higher cure rate than the control group[56.52%(39/69)](χ2=4.17,P<0.05) and total effective rate of chest X-ray [97.98%(97/99)] than the control group[86.27%(44/51)] (χ2=12.98,P<0.01). The observation group was superior to the control group in the alleviation of TCM syndrome under the condition of 0-3 g dose stratification on day 3 of medication (P<0.01). The recovery time, time to complete fever abatement, time to fever abatement and expectoration alleviation, rate of conversion to severe case, and reduction in the frequency of antibiotic use showed no significant differences between the two groups. In terms of safety, 13 and 7 adverse events occurred in the observation group and control group, respectively, which were relieved or disappeared after drug withdrawal or symptomatic treatment and showed no significant difference between the two groups. ConclusionIntravenous drip of ceftriaxone sodium combined with An'erning granules is effective in the treatment of community-acquired pneumonia in children. It can accelerate the absorption of pulmonary inflammation, alleviate the clinical symptoms in a short time for young children or the children with mild symptoms, and is safe in clinical application.

Macroautophagy (referred to as autophagy hereafter) is a major intracellular lysosomal degradation pathway that is responsible for the degradation of misfolded/damaged proteins and organelles. Previous studies showed that autophagy protects against acetaminophen (APAP)-induced injury (AILI) via selective removal of damaged mitochondria and APAP protein adducts. The lysosome is a critical organelle sitting at the end stage of autophagy for autophagic degradation via fusion with autophagosomes. In the present study, we showed that transcription factor EB (TFEB), a master transcription factor for lysosomal biogenesis, was impaired by APAP resulting in decreased lysosomal biogenesis in mouse livers. Genetic loss-of and gain-of function of hepatic TFEB exacerbated or protected against AILI, respectively. Mechanistically, overexpression of TFEB increased clearance of APAP protein adducts and mitochondria biogenesis as well as SQSTM1/p62-dependent non-canonical nuclear factor erythroid 2-related factor 2 (NRF2) activation to protect against AILI. We also performed an unbiased cell-based imaging high-throughput chemical screening on TFEB and identified a group of TFEB agonists. Among these agonists, salinomycin, an anticoccidial and antibacterial agent, activated TFEB and protected against AILI in mice. In conclusion, genetic and pharmacological activating TFEB may be a promising approach for protecting against AILI.
