Phosphorylated (p-) NF-κB p65 and NF-κB inhibitor α (IκB-α) protein expression levels were also determined using western blotting. Puerarin treatment reduced the levels of inflammatory cytokines in the BALF. Furthermore, puerarin treatment significantly decreased the levels of Ang II, AT1-R and ACE, which were increased following smoke inhalation. Conversely, puerarin treatment upregulated the expression of ACE2, which was downregulated following smoke inhalation. Additionally, puerarin decreased the expression of p-NF-κB p65 and increased that of IkB-α. Thus, the antiinflammatory effects of puerarin were partly mediated via the RAS and via regulation of the NFĸB signaling pathway in rats with gunpowder smog-induced ALI.Because damage to hyaline cartilage is irreversible, relieving progressive cartilage destruction is an important therapeutic approach for inflammatory arthritis. In the present study, human hyaline chondrocytes were isolated from total knee replacements of 15 patients with osteoarthritis (OA) and three with rheumatoid arthritis (RA). Synovial fluid of OA (n=25) and RA (n=34) were collected to measure tumor necrosis factor α (TNFα) using ELISA. Consistent with previous studies, the synovial fluid exhibited high TNFα levels and hyaline cartilage was severely destroyed in patients with RA. TNFα-treated chondrocytes were used as model for inflammatory arthritis. TNFα did not influence proliferation or extracellular matrix expression in chondrocytes, but induced matrix metalloproteinase (MMP)1, 3 and 13 expression levels in chondrocytes, which was accompanied by activation of nuclear factor-κB signaling. During chondrogenic differentiation, TNFα attenuated mRNA expression levels of anabolic factors (collagen type 2 and aggrecan) and enhanced mRNA expression of catabolic factors (MMP1, MMP3 and MMP13) in chondrocytes. Moreover, anti-TNFα agents (Golimumab) inhibited the TNFα-induced metabolic shift in chondrocytes and chondrogenic differentiation. The present study revealed a mechanism by which TNFα may induce metabolic shift in chondrocytes, leading to progressive chondrocyte destruction.Melastoma dodecandrum Lour. ACBI1 mouse (MDL) is component used in traditional Chinese medicine that is widely distributed throughout southern China. MDL has been long utilized in clinical treatment for various conditions, such as inflammation. However, the toxicity and underlying anti-inflammatory mechanism of MDL remain to be elucidated. In the present study, Sprague-Dawley rats received intragastric administration of MDL for 2 months, and the toxicity of MDL was investigated. The rats were treated with lipopolysaccharide (LPS) for 8 h to determine the potential anti-inflammatory mechanism of MDL. The results demonstrated that MDL alone did not affect the expression levels of factors associated with inflammation (IL-1β, IL-6 and TNF-α) and oxidative stress [malondialdehyde (MDA), superoxide dismutase (SOD) and nitric oxide (NO)] in the rat serum and exerted no effects on rat liver and kidneys. By contrast, MDL attenuated LPS-induced inflammation and oxidative stress by regulating specific cytokines, such as IL-1β, IL-6, TNF-α, MDA, SOD and NO in the rat serum and alleviated LPS-induced liver and kidney damage. Additionally, compared with the LPS group, MDL inhibited CD4+ T cell differentiation into Th1 and Th17 cells and enhanced CD4+ T cell differentiation into Th2 and Treg cells. MDL also suppressed reactive oxygen species (ROS) production and mitochondrial apoptosis by modulating mitochondrial apoptosis-related proteins in spleen CD4+ T cells. In conclusion, the results of the present study demonstrated the non-toxic nature of MDL and revealed that it alleviated LPS-induced inflammation and oxidative stress by regulating differentiation and ROS production in CD4+ T cells.The present study aimed to explore the effectiveness of endoscopic submucosal dissection (ESD) in the treatment of early gastric cancer (EGC) and its effect on serum tumor-associated trypsin-2 (TAT-2) and Golgi protein 73 (GP73) expression levels to provide a reference for the treatment of EGC. TAT-2 is a proteolytic target enzyme for tumor-associated trypsin inhibitor that has been previously reported to enhance invasion by promoting extracellular matrix degradation. GP73 is a novel type II Golgi membrane protein of unknown function that is expressed in the hepatocytes of patients with adult giant-cell hepatitis. A total of 161 patients with EGC treated at our hospital from April 2013 to February 2014 were selected as the study subjects. Among these, 86 patients underwent ESD (group A) and the remaining 75 underwent endoscopic mucosal resection (group B). Treatment effectiveness, incidence of complications and adverse reactions, operation time, intraoperative blood loss and length of hospital stay, as well as serum TAT-2 and GP73 expression levels, were compared between the two groups. The treatment effectiveness was significantly higher in group A than in group B (P0.05). In conclusion, ESD had a good therapeutic effect on EGC and is able to decrease serum TAT-2 expression levels and increase serum GP73 expression levels. The present study was registered into the Chinese Trials Registry (registration no. NCT02157534).The present study aimed to validate the hypothesis that negative symptoms of schizophrenia encompass two domains, namely avolition-apathy (AA) and diminished expression (DE), and to investigate the relationship of these domains with behavioral outputs which imply hedonic activities Cigarette use and weight gain. A total of 106 consecutive schizophrenia outpatients with primary negative symptoms were evaluated using the Positive and Negative Syndrome Scale (PANSS), the Negative Symptoms Assessment Scale (NSA-16), the Calgary Depression Scale for Schizophrenia (CDSS), and the Simpson-Angus Scale (SAS). A semi-structured interview was used to assess demographic features, the number of cigarettes smoked per day, and body mass index. Data were analyzed using descriptive statistics, principal component analysis, analysis of variance, and covariance. A two-factor solution was revealed for the negative symptoms of schizophrenia represented by AA and DE. Analyses of variance and covariance suggested that higher AA scores were associated with normal weight and non-smoking status. No significant differences were revealed regarding DE scores in relationship with the same behavioral hedonic outputs. The present results indicated the AA and DE domains exhibit meaningful differences concerning the outcome, which may imply the need for different approaches regarding rating and treatment.Anorexia nervosa is an eating disorder characterized by restrictive eating and an intense fear of gaining weight. It is a disease with an increasing incidence during the last few decades, and represents a complex psychiatric condition which includes secondary amenorrhea, nutritional and metabolic damage, and impaired endocrine panel up to bone loss as well as cardiac, gastrointestinal and hematological complications. This is a narrative review which includes an update on this eating disorder from the perspective of an endocrine panel of anomalies, especially of the skeleton, considering the pressure of the recent global COVID-19 pandemic changes. Practically affecting every organ, anorexia nervosa needs to be taken into consideration during the pandemic period because of the higher risk of relapse due to new living conditions, social distancing, self-isolation, changes in food access, more intense use of social media platforms, disruption of daily habits, and more difficult access to healthcare practitioners. The lack of physical activity in addition to vitamin D deficiency related to low sun exposure or to the use of facial masks may also be connected to further bone damage related to this disease.Syphilis is the most common sexually transmitted disease that mainly affects socially active people, with a fluctuating worldwide incidence over the years. A retrospective study was conducted over a period of 10 years (2009-2018) that included 396 patients with syphilis diagnosed and monitored by Sibiu County Emergency Clinical Hospital, Romania. During this period (2009-2018), we observed a decrease in the new cases of syphilis by 35.90%, and the average syphilis incidence was 9.90 new cases per 100,000 inhabitants. Syphilis was diagnosed more frequently in men with an average age of 35.39 years, from urban areas, with and educational level of grades 9-12, unmarried, workers, or without occupation. Out of the 396 patients with syphilis, about 6% were HIV coinfected. Over half of the HIV coinfected cases were declared MSM (men who have sex with men), and 40% of these cases were registered in 2018. The most common clinical stage of syphilis was the latent form (67.93%). Regarding the syphilis treatment regimen, we noted the transition from the classic regimen with benzathine-penicillin G (100% in 2009) to alternative therapies (mainly with cephalosporins) in 2018 (56.86%). Our findings showed that in the last 10 years in our county, the incidence of syphilis had a downward trend, but with an increase in syphilis-HIV co-infection and neurosyphilis cases.Sleep disturbances in systemic lupus erythematosus (SLE) are not well understood. The restless legs syndrome (RLS) is one of the frequent occurring sleep disturbances in SLE. The aim of this study was to evaluate the prevalence of RLS and its characteristics in SLE. We evaluated, in a prospective case-control study, 26 patients with SLE and 26 patients without SLE in an age- and sex-matched control group. An RLS-positive diagnosis met International RLS Study Group (IRLSSG) criteria. We used standardized questionnaires, which included demographic data, medical history and sleep assessment. We used validated questionnaires and scales to assess sleep. There were 23/26 females (88.46%) in each group; the mean patient age in the SLE subgroup was 51.65 years, while in the control subgroup, 52.07 years (range 30-74). Nine (34.2%) patients had RLS-positive criteria in the SLE group and 2 (7.69%) of 26 in the control group. Eight out of 9 patients described RLS onset after SLE was diagnosed. In the SLE group, 8 cases were of moderate severity and 1 was considered mild. The control group had one mild and one moderate case of RLS. RLS prevalence in SLE is higher and the quality of sleep is poorer compared with the control group.The present study was designed to analyze the expression of pregnancy-associated plasma protein-A (PAPP-A) in the serum of patients with ectopic pregnancy (EP) and related factors inducing this condition. Seventy-five patients with EP admitted to the Affiliated Hospital of Jining Medical University from January 2018 to February 2019 were selected as the research group, and another 59 healthy pregnant women of the corresponding age, gravidity and gestational week were enrolled in the control group. ELISA was employed to detect the serum expression levels of PAPP-A and inflammatory factors such as interleukin-8 (IL-8) and tumor necrosis factor-α (TNF-α). ROC was adopted to evaluate the diagnostic value of serum PAPP-A in patients with EP, and Pearson correlation coefficient was applied to analyze the correlation of PAPP-A with inflammatory factors IL-8 and TNF-α. Serum PAPP-A expression was significantly lower in EP patients than those in the control group. The area under the curve (AUC) of serum PAPP-A in diagnosing EP patients was 0.
