Background: To explore the prevalence of lymphocyte subgroups $CD3^+$ $CD4^+$ and $CD3^+$ $CD8^+$ and their surface receptors NKG2D and NKG2A in patients with non-small cell lung cancer (NSCLC). Materials and Methods: A total of 40 patients with NSCLC were divided into different groups according to different clinical factors (TNM staging, pathological patterns and genders) for assessment of relations with $CD3^+$ $CD4^+$ and $CD3^+$ $CD8^+$ and the surface receptors NKG2D and NKG2A of T lymphocytes in peripheral blood by flow cytometry. Results: Patients in the advanced group had evidently lower levels of $CD3^+$ $CD4^+$ but markedly higher levels of $CD3^+$ $CD8^+$ in peripheral blood than those with early lesions (p<0.05). In addition, NSCLC patients in the advanced group had obviously higher $CD3^+$ $CD4^+$ NKG2D and $CD3^+$ $CD8^+$ NKG2A expression rates but lower $CD3^+$ $CD4^+$ NKG2A and $CD3^+$ $CD8^+$ NKG2D expression rates (p<0.05). However, there were no significant differences between NSCLC patients with different genders and pathological patterns in expression levels of lymphocyte subgroups $CD3^+$ $CD4^+$ and $CD3^+$ $CD8^+$ and their surface receptors NKG2D and NKG2A. Conclusions: Unbalanced expression of surface receptors NKG2D and NKG2A in $CD3^+$ $CD4^+$ and $CD3^+$ $CD8^+$ lymphocytes may be associated with a poor prognosis, greater malignancy and immunological evasion by advanced cancers, related to progression of lung cancer.

Objective: To explore the feasibility of pulmonary lobectomy combined with pulmonary arterioplasty by complete video-assisted thoracic surgery (VATS) in patients with lung cancer, and summarize its surgical methods. Materials and Methods: Twenty-one patients with lung cancer in Beijing Chest Hospital Affiliated to Capital Medical University from Feb., 2010 to Jun., 2013 were selected, males and females accounting for 15 and 6 cases, respectively. Ten underwent right upper lobectomy, 5 right lower lobectomy, 4 left upper lobectomy (in which left upper sleeve lobectomy was conducted for 2) and 2 left lower lobectomy. At the same time, local resection of pulmonary arterioplasty was performed for 12 patients, and sleeve resection of pulmonary arterioplasty for 9. Results: Twenty-one patients recovered well after surgery. Thoracic drainage tube was maintained for 3-8 days, with an average of 4.9 days, and hospital stays were 8-15 days, with an average of 11 days. There were no deaths in the perioperative period, and the complications like pulmonary embolism, bronchopleural fistula, chest infection and pulmonary atelectasis did not occur after surgery. Conclusions: Performance of pulmonary lobectomy and pulmonary arterioplasty together by complete VATS is a safe and effective surgical method, which can expand the indications of patients with lung cancer undergoing thoracoscopic pulmonary lobectomy, and make more patients profit from such minimally invasive treatment.

Microbial metabolites have emerged as critical components that mediate the metabolic effects of the gut microbiota. Here, we show that indole-3-propionic acid (IPA), a tryptophan metabolite produced by gut bacteria, is a potent anti-non-alcoholic steatohepatitis (NASH) microbial metabolite. Here, we demonstrate that administration of IPA modulates the microbiota composition in the gut and inhibits microbial dysbiosis in rats fed a high-fat diet. IPA induces the expression of tight junction proteins, such as ZO-1 and Occludin, and maintains intestinal epithelium homeostasis, leading to a reduction in plasma endotoxin levels. Interestingly, IPA inhibits NF-κB signaling and reduces the levels of proinflammatory cytokines, such as TNFα, IL-1β, and IL-6, in response to endotoxin in macrophages to repress hepatic inflammation and liver injury. Moreover, IPA is sufficient to inhibit the expression of fibrogenic and collagen genes and attenuate diet-induced NASH phenotypes. The beneficial effects of IPA on the liver are likely mediated through inhibiting the production of endotoxin in the gut. These findings suggest a protective role of IPA in the control of metabolism and uncover the gut microbiome and liver cross-talk in regulating the intestinal microenvironment and liver pathology via a novel dietary nutrient metabolite. IPA may provide a new therapeutic strategy for treating NASH.

Hepatitis B protein x (HBx) has been reported to promote tumorigenesis in hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC), but the mechanism awaits further investigation. In this study, we found that cFAM210A (a circular RNA derived from the third exon of transcript NM_001098801 of the FAM210A gene; CircBase ID: hsa_circ_0003979) can be silenced by HBx. cFAM210A expression was downregulated and negatively correlated with tumorigenesis in patients with HBV-related HCC. Furthermore, cFAM210A reduced the proliferation, stemness, and tumorigenicity of HCC cells. Mechanistically, HBx increased the N6-methyladenosine (m6A) level of cFAM210A by promoting the expression of RBM15 (an m6A methyltransferase), thus inducing the degradation of cFAM210A via the YTHDF2-HRSP12-RNase P/MRP pathway. cFAM210A bound to YBX1 and inhibited its phosphorylation, suppressing its transactivation function toward MET. These findings suggest the important role of circular RNAs in HBx-induced hepatocarcinogenesis and identify cFAM210A a potential target in the prevention and treatment of HBV-related HCC.
