Results: The study included 41 patients from 8 medical centers.

A burns and COVID-19 shared stress responding gene network deciphers CD1C-CD141- DCs as the key cellular components in septic prognosis.

Differential body responses to various stresses, infectious or noninfectious, govern clinical outcomes ranging from asymptoma to death. However, the common molecular and cellular nature of the stress responsome across different stimuli is not described. In this study, we compared the expression behaviors between burns and COVID-19 infection by choosing the transcriptome of peripheral blood from related patients as the analytic target since the blood cells reflect the systemic landscape of immune status.

Impact of initial chemotherapy cycles and clinical characteristics on outcomes for HIV-associated diffuse large B cell lymphoma patients: The Central and Western China AIDS Lymphoma League 001 study (CALL-001 study).

Introduction: Little is known about the first line induction chemotherapy cycles for HIV-associated diffuse large B-cell lymphoma (DLBCL) as these are less common than HIV-negative lymphoma. Currently, the optimal treatment cycles option remains undefined. Therefore, we performed a multi-center study to analyze the clinical characteristics and outcomes of HIV-associated DLBCL patients in different treatment modes in China.

Identification of pathological-related and diagnostic potential circular RNAs in Stanford type A aortic dissection.

Introduction: Stanford type A aortic dissection (TAAD) is one of the lethal macrovascular diseases caused by the invasion of blood into the media layer of ascending aortic wall. Inflammation, smooth muscle dysfunction, and extracellular matrix (ECM) degradation were regarded as the major pathology in affected tissue. However, the expression pattern and its regulation especially through circular RNAs (circRNAs) as an overall characteristic of TAAD molecular pathology remain unclear.

Background: Periodontitis is considered a risk factor for atherosclerosis, but the mechanism is not clear. It was reported that oral administration of altered the gut microbiota in mice. Gut dysbiosis and the intestinal metabolite trimethylamine N-oxide (TMAO) were verified to be associated with atherosclerosis.

Statin Treatment Induced a Lipogenic Expression Hierarchical Network Centered by SREBF2 in the Liver.

Statin treatment is a major prevention treatment for hypercholesterolemia and the management of patients with increased risk of cardiovascular disease (CVD) due to its protective effects. However, its long-term safety was questioned regarding its potential role in new-onset type 2 diabetes mellitus, and its effect on gene regulation in the liver is not yet fully understood. By reanalyzing the transcriptome of the livers of patients with obesity and hypercholesterolemia, this study shows a multiple module organization that is related to various clinical metabolic parameters and identified an expression hierarchical network involving cholesterol and fatty acid syntheses in the liver of statin-treated patients.

Clinical characteristics and outcomes in HIV-associated diffuse large B-cell lymphoma in China: A retrospective single-center study.

Human immunodeficiency virus (HIV) infection is associated with an increased risk of aggressive lymphoma, especially diffuse large B cell lymphoma (DLBCL). There are few data regarding HIV-associated DLBCL in China. Therefore, we analyzed the characteristics and outcomes of patients with HIV-associated DLBCL from our center.

The Value of Nutritional Status in the Prognostic Analysis of Patients with AIDS-Related Lymphoma.

Objective: Many studies have suggested that indexes of nutritional status, such as body mass index (BMI), serum albumin (ALB), serum pre-albumin (PA), and hemoglobin, may be used as risk factors for the prognosis of HIV or lymphoma. Therefore, this study aimed to retrospectively analyze and explore the value of nutritional status in the prognostic assessment of patients with AIDS-related lymphoma (ARL).

Methods: In this retrospective study, the clinical data of 69 patients with ARL were collected.

The knockdown of LncRNA AFAP1-AS1 suppressed cell proliferation, migration, and invasion, and promoted apoptosis by regulating miR-545-3p/hepatoma-derived growth factor axis in lung cancer.

Lung cancer is one of the most common human cancers. Long noncoding RNA AFAP1-AS1 (LncRNA AFAP1-AS1) and microRNA-545-3p (miR-545-3p) were reported to play important roles in lung cancer development. This study aimed to elucidate the functional mechanisms of AFAP1-AS1 and miR-545-3p in lung cancer.

Puerarin Increases Survival and Protects Against Organ Injury by Suppressing NF-κB/JNK Signaling in Experimental Sepsis.

Puerarin, an isoflavonoid rich in Radix , has been reported to be a broadly effective regulator in various biological processes and clinic conditions. However, the role of puerarin in sepsis-induced mortality with multiple-organ injury remains unknown. Herein, we showed that puerarin potently attenuated organ injury and increased survival rate in both lipopolysaccharides (LPS) and cecal ligation and puncture (CLP) induced mouse sepsis models.

FLCN-regulated miRNAs suppressed reparative response in cells and pulmonary lesions of Birt-Hogg-Dubé syndrome.

Background: Birt-Hogg-Dubé Syndrome (BHDS) characterised by skin fibrofolliculomas, kidney tumour and pulmonary cysts/pneumothorax is caused by folliculin (FLCN) germline mutations. The pathology of both neoplasia and focused tissue loss of BHDS strongly features tissue-specific behaviour of the gene. Isolated cysts/pneumothorax is the most frequent atypical presentation of BHDS and often misdiagnosed as primary spontaneous pneumothorax (PSP).

Borneol alleviates brain injury in sepsis mice by blocking neuronal effect of endotoxin.

Aim: Brain injury after sepsis leads to high mortality and long-term brain dysfunction in patients. Previous studies revealed that borneol has a protective effect on the brain, but its function on sepsis associated encephalopathy (SAE) remains unknown. Herein, we investigated the protective effect of borneol against sepsis-related brain injury.

Puerarin prevents high-fat diet-induced obesity by enriching Akkermansia muciniphila in the gut microbiota of mice.

Growing evidence indicates that the gut microbiota plays a significant role in the pathophysiological processes of obesity and its related metabolic symptoms in the host. Puerarin, an active ingredient in the root of Pueraria lobate has been suggested to have a potent anti-obesity effect. Herein, we tested whether this effect of puerarin is associated with changes in the gut microbiota.

Remission of HIV-related naïve and high-risk Burkitt's lymphoma treated by autologous stem cell transplantation plus cART.

A 27-year-old male with HIV-associated naïve and high-risk Burkitt's lymphoma sequentially received short-term, high-dose non-myeloablative chemotherapy and autologous CD34-positive stem cell transfusion in the setting of combined antiretroviral therapy (cART). Prompt hematopoietic recovery was observed after 2 weeks and clinical remission from Burkitt's lymphoma within approximately 30 months after transplantation. The HIV RNA load was inhibited persistently, and drug resistance was not observed.

Methods: In this multicenter, retrospective study, data were collected from adults hospitalized with A(H7N9) infection during 2013-2017 in China. We compared clinical features and A(H7N9) shedding among patients with different NAI doses and combination therapies and evaluated factors associated with A(H7N9) shedding, using Cox proportional hazards regression.

Effect of puerarin in promoting fatty acid oxidation by increasing mitochondrial oxidative capacity and biogenesis in skeletal muscle in diabetic rats.

Background: Type 2 diabetes is characterized by dyslipidemia and the accumulation of lipids in non-adipose tissue, including skeletal muscle. Puerarin, which is a natural isoflavonoid isolated from the root of the plant Pueraria lobata, has been shown to have antidiabetic activity. However, the lipid-reducing effect of puerarin, in particular in skeletal muscle, has not yet been addressed.

Puerarin acts on the skeletal muscle to improve insulin sensitivity in diabetic rats involving μ-opioid receptor.

Puerarin, a major active isoflavone extracted from the root of Pueraria lobate, significantly increases plasma β-endorphin and insulin levels and improves impaired insulin signaling in diabetic animals. However, the target tissues and underlying mechanisms in and through which puerarin functions to ameliorating insulin resistance remains largely unclear. In this study, we showed that puerarin enhanced μ-opioid receptor expression and phosphorylation, and increased insulin-stimulated glucose transporter 4 translocation to the plasma membrane in the skeletal muscle of diabetic rats, which were recaptured by a direct application of puerarin in the palmitate-induced insulin-resistant L6 myotubes.

Luteolin selectively kills STAT3 highly activated gastric cancer cells through enhancing the binding of STAT3 to SHP-1.

The antitumor effect of luteolin, a plant flavonoid, in gastric cancer (GC) cells has not been fully understood. Here we show that luteolin selectively kills STAT3 overactivated GC cells that are often drug resistant. The treatment of luteolin in these GC cells significantly inhibited STAT3 phosphorylation and reduced the expression of STAT3 targeting gene Mcl-1, Survivin and Bcl-xl.
