Objective To evaluate the biochemical indicators,nutritional status,and immune levels of pa-tients with pulmonary aspergillosis(PA)and other pulmonary diseases,and to construct a predictive model for PA so as to improve the diagnostic efficacy of clinical PA.Methods A total of 40 PA patients and 39 pa-tients with other pulmonary diseases who were hospitalized in the hospital from January 2020 to August 2022 were retrospectively analyzed.The expression trends and differences of serum 1,3-β-D Glucan(G test),galac-tomannan test(GM test),biochemical indexes,blood routine indexes and immune cell subsets were analyzed and compared.The receiver operating characteristic(ROC)curve and binary Logistic regression analysis were used to construct the predictive model for PA by the combination of clinical indicators.Results Serum GM test,G test,albumin,hemoglobin,hematocrit,lymphocytes,B lymphocytes,CD44 T lymphocytes and CD4/CD8 ratio displayed significant differences between PA patients and patients with other lung disease(P＜0.05).The levels of GM test in alveolar lavage fluid of PA patients were significantly higher than that in the serum,and the differences were statistically significant(P＜0.05).The ROC curve analysis showed that the GM test,as an independent predictor of PA,had good predictive accuracy[0.85＜area under the curve(AUC)＜0.95].Besides,albumin,natural killev cells,CD4+T lymphocytes and CD4/CD8 ratio had general predictive efficacy(0.70＜AUC＜0.85).The prediction efficacy of G test and B lymphocytes was poor(AUC＜0.70).The Logistic regression analysis showed that the combination of GM test and serum albumin could construct the optimal prediction model,and the prediction formula of the combined model was as fol-lows:Logit(P)=17.781× GM-0.131×albumin+1.394.The prediction accuracy of the combined model was 0.924(95％CI:0.865-0.982),the sensitivity was 87.5％,the specificity was 81.2％,and the cut off value was 17.781×GM-0.131×albumin-1.735.Conclusion This study retrospectively analyzed the differences in various clinical indicators between patients with PA and patients with other pulmonary diseases,and then screen the key clinical indicators as candidate predictors which displayed significantly different ex-pression between the two groups.The optimal prediction model for the diagnosis of PA is constructed by the combination of GM test and serum albumin through ROC curve and Logistic regression analysis.This model may significantly improve the diagnostic efficiency of PA in clinical,and provide the reference for the early di-agnosis and effective treatment of PA patients.

Objective:To analyze the hotspots of international acupuncture research; To evaluate the influence of each hotspot; To explore its development trend.Methods:Acupuncture research related literature was retrieved from the Web of Science core database from January 1, 2019 to January 1, 2022. 42 highly cited literature was extracted using BICOMB 2.01 software, and a 42×42 co-occurrence matrix was constructed. A co-citation cluster analysis figure was drawn with SPSS 26.0 software. The CPT values of each hotspot identified in the cluster figure were computed using the formula CPT=(C/P)/T=C/(P·T). Bubble charts were drawn to show each hotspot's annual publication of articles.Results:Totally 23 research hotspots were identified, including consensus on the quality of evidence and recommendation intensity, assessment of the efficacy of acupuncture for chronic pain and analgesic mechanisms of acupuncture. The bubble chart showed that the annual attention of 23 hotspots varied, with 14 hotspots increasing year by year, 5 hotspots remaining stable, and only 4 hotspots decreasing year by year.Conclusions:The study has found that the direction of acupuncture research in the past three years focuses on acupuncture indication research, acupuncture mechanism research and evidence-based methodology research. China is the main contributor to the expansion of acupuncture indication research. The international trend of acupuncture development is obvious. Chinese acupuncture research faces greater competitive pressure, and the influence of core papers is insufficient.

【Objective】 This study aims to summarize the hotspots of acupuncture research in China and abroad in recent 10 years. 【Methods】 The core collection of Web of Science was retrieved, and the literature on experimental and clinical research of acupuncture in China and abroad was collected from January 1, 2012 to December 31, 2021. The included literature was visually analyzed using CiteSpace 6.1.R3. Statistical analysis was carried out in the annual number of papers, authors, countries, and journals. According to the author's country, the literature was divided into Chinese and global categories for keywords clustering analysis and co-citation references analysis independently to obtain hotspots and trends in acupuncture research. 【Results】 There are 1 215 articles in acupuncture experimental medicine, 3 805 articles in acupuncture clinical medicine in China; 551 articles in acupuncture experimental medicine, and 4 538 articles in acupuncture clinical medicine abroad. The number of articles on acupuncture abroad remains stable and flat, whereas the annual number of domestic papers shows a continuously growth trend. LIU Cunzhi from Beijing Hospital of Traditional Chinese Medicine affiliated to Capital Medical University in China is the author who has published the most articles in the field of acupuncture in the recent decade. China is the most productive country in publishing such research articles. Evidence-based Comprehensive and Alternative Medicine is the journal with the most published articles. The mechanisms of acupuncture on nerve regeneration or nerve recovery and research on the mechanisms of acupuncture analgesia are hotspots in experimental acupuncture research, and the treatment of neuropathic pain and dysfunctional diseases with acupuncture are hotspots in clinical acupuncture research in China. Research on the mechanism of protection of the cardiovascular system by acupuncture and research on the mechanism of analgesia by acupuncture are hotspots in experimental research on acupuncture abroad. Studies on the amelioration of inflammatory pain and psychological or psychiatric disorders by acupuncture also serve as hotspots in clinical research on acupuncture abroad. 【Conclusion】 Acupuncture research in China focuses on the treatment of internal diseases and visceral pain, while acupuncture research abroad concentrates on the alleviation and improvement of cancer and psychological and mental diseases. Treatment of internal diseases and mental diseases with acupuncture is the trend of future research.

Early weaned piglets suffer from oxidative stress and enteral infection, which usually results in gut microbial dysbiosis, serve diarrhea, and even death. Rice bran oil (RBO), a polyphenol-enriched by-product of rice processing, has been shown to have antioxidant and anti-inflammatory properties both in vivo and in vitro. Here, we ascertained the proper RBO supplementation level, and subsequently determined its effects on lipopolysaccharide (LPS)-induced intestinal dysfunction in weaned piglets. A total of 168 piglets were randomly allocated into four groups of seven replicates (42 piglets each group, (21±1) d of age, body weight (7.60±0.04) kg, and half males and half females) and were given basal diet (Ctrl) or basal diet supplemented with 0.01% (mass fraction) RBO (RBO1), 0.02% RBO (RBO2), or 0.03% RBO (RBO3) for 21 d. Then, seven piglets from the Ctrl and the RBO were treated with LPS (100 μg/kg body weight (BW)) as LPS group and RBO+LPS group, respectively. Meanwhile, seven piglets from the Ctrl were treated with the saline vehicle (Ctrl group). Four hours later, all treated piglets were sacrificed for taking samples of plasma, jejunum tissues, and feces. The results showed that 0.02% was the optimal dose of dietary RBO supplementation based on diarrhea, average daily gain, and average daily feed intake indices in early weaning piglets. Furthermore, RBO protected piglets against LPS-induced jejunal epithelium damage, which was indicated by the increases in villus height, villus height/crypt depth ratio, and Claudin-1 levels, as well as a decreased level of jejunal epithelium apoptosis. RBO also improved the antioxidant ability of LPS-challenged piglets, which was indicated by the elevated concentrations of catalase and superoxide dismutase, and increased total antioxidant capacity, as well as the decreased concentrations of diamine oxidase and malondialdehyde in plasma. Meanwhile, RBO improved the immune function of LPS-challenged weaned piglets, which was indicated by elevated immunoglobulin A (IgA), IgM, β‍‍-defensin-1, and lysozyme levels in the plasma. In addition, RBO supplementation improved the LPS challenge-induced dysbiosis of gut microbiota. Particularly, the indices of antioxidant capacity, intestinal damage, and immunity were significantly associated with the RBO-regulated gut microbiota. These findings suggested that 0.02% RBO is a suitable dose to protect against LPS-induced intestinal damage, oxidative stress, and jejunal microbiota dysbiosis in early weaned piglets.

Abstract: Ovarian cancer is a gynecological malignant tumor with the highest fatality rate. It is characterized by concealed onset and poor prognosis. Recent studies have found that carbohydrate intake, food glycemic index and food glycemic load are closely related to the incidence of ovarian cancer. In this article, we summarize the current progress of the above-mentioned research and provide references for the prevention and future research of ovarian cancer.

Dysregulation of mTORC1/mTORC2 pathway is observed in many cancers and mTORC1 inhibitors have been used clinically in many tumor types; however, the mechanism of mTORC2 in tumorigenesis is still obscure. Here, we mainly explored the potential role of mTORC2 in esophageal squamous cell carcinoma (ESCC) and its effects on the sensitivity of cells to mTOR inhibitors. We demonstrated that RICTOR, the key factor of mTORC2, and p-AKT (Ser473) were excessively activated in ESCC and their overexpression is related to lymph node metastasis and the tumor-node-metastasis (TNM) phase of ESCC patients. Furthermore, we found that mTORC1/ mTORC2 inhibitor PP242 exhibited more efficacious anti-proliferative effect on ESCC cells than mTORC1 inhibitor RAD001 due to RAD001-triggered feedback activation of AKT signal. Another, we demonstrated that down-regulating expression of RICTOR in ECa109 and EC9706 cells inhibited proliferation and migration as well as induced cell cycle arrest and apoptosis. Noteworthy, knocking-down stably RICTOR significantly suppresses RAD001-induced feedback activation of AKT/PRAS40 signaling, and enhances inhibition efficacy of PP242 on the phosphorylation of AKT and PRAS40, thus potentiates the antitumor effect of RAD001 and PP242 both and . Our findings highlight that selective targeting mTORC2 could be a promising therapeutic strategy for future treatment of ESCC.

In the past decade, the role of the mevalonic acid pathway and its inhibitor statins in preventing tumorigenesis and improving tumor prognosis has attracted wide attention; however, so far, there are still controversies over the role of statins in liver cancer. Previous studies have shown that statins play an important role in cholesterol metabolism, antioxidation, and anti-inflammation, and cholesterol metabolism, oxidative stress, and inflammatory response are important factors to promote the development and progression of liver cancer. However, some recent studies have found that statins have an adverse effect on the treatment of some liver cancer patients. This article elaborates on the role of statins as a “double-edged sword” in the treatment of liver cancer and related molecular mechanisms.

Objective: To describe the dermoscopic features of extramammary Paget′s disease (EMPD) and chronic eczema of the vulva, and to explore the value of dermoscopy in the diagnosis and differential diagnosis of the above diseases. Methods: Dermoscopic images were collected from 20 patients with histopathologically confirmed vulvar EMPD and 16 patients with clinically confirmed chronic eczema of the vulva in Hospital for Skin Diseases, Chinese Academy of Medical Sciences and Pekin Union Medical College from January 2017 to April 2018, and retrospectively analyzed. Fisher′s exact test was used to compare the prevalence of dermoscopic features between the two groups. Results: As dermoscopy showed, the milky red background was observed in 19 EMPD patients and in only 1 patient with chronic eczema, and there was a significant difference in the prevalence of milky red background between the two groups (P < 0.001) . White scales were the most common desquamation, and were observed in 9 EMPD patients and 13 patients with chronic eczema (P = 0.128) . Blood vessels were uniformly distributed in EMPD patients, including dotted-globular vessels in 19 and linear vessels in 14, while blood vessels were distributed in a patchy or clustered pattern in the patients with chronic eczema, including dotted-globular vessels in 16 and linear vessels in 7. There was a significant difference in the prevalence of different distribution patterns of blood vessels between the two groups (P < 0.001) . Bright white streaks, bright white structureless area and reticular structure were observed in 19, 20 and 19 EMPD patients respectively, and in 1, 1 and 1 patient with chronic eczema respectively, and there were significant differences in the prevalence of the above 3 structures between the two diseases (all P < 0.001) . Conclusion Vulvar EMPD and chronic eczema both show characteristic dermoscopic features, and dermoscopy is of great value to the diagnosis and differential diagnosis of EMPD.
