Because of its importance in tumor invasion and metastasis, the epithelial-mesenchymal transition (EMT) has become a research focus in the field of cancer. Recently, evidence has been presented that FoxO4 might be involved in EMT. Our study aimed to detect the expression of FoxO4, E-cadherin and vimentin in non-small cell lung cancers (NSCLCs). We also investigated clinical features and their correlations with the markers. In our study, FoxO4, E-cadherin and vimentin were assessed by immunohistochemistry in a tissue microarray (TMA) containing 150 cases of NSCLC. In addition, the expression level of FoxO4 protein was determined by Western blotting. The percentages of FoxO4, E-cadherin and vimentin positive expression in NSCLCs were 42.7%, 38.7% and 55.3%, respectively. Immunoreactivity of FoxO4 was low in NSCLC when compared with paired normal lung tissues. There were significant correlations between FoxO4 and TNM stage (P<0.001), histological differentiation (P=0.004) and lymph node metastasis (P<0.001), but no significant links with age (P=0.323), gender (P=0.410), tumor size (P=0.084), smoking status (P=0.721) and histological type (P=0.281). Our study showed that low expression of FoxO4 correlated with decreased expression of E-cadherin and elevated expression of vimentin. Cox regression analysis indicated FoxO4 to be an independent prognostic factor in NSCLC (P=0.046). These data suggested that FoxO4 might inhibit the process of EMT in NSCLC, and might therefore be a target for therapy.

Background There are several effective complementary and integrative therapies for patients with severe COVID-19. The trial aims to evaluate the efficacy and advantages of the qigong exercise and acupressure rehabilitation program (QARP) for treating patients with severe COVID-19. Methods A total of 128 patients with COVID-19 aged 20 to 80 years were recruited and randomly allocated in a 1:1 ratio to receive QARP plus standard therapies or standard therapies alone. QARP consisted of acupressure therapy and qigong exercise (Liu Zi Jue). The primary outcome was measured with the modified Medical Research Council (mMRC) dyspnea scale, and the secondary outcomes included the modified Borg dyspnea scale (MBS), fatigue Scale-14 (FS-14), patient health questionnaire-9 scale (PHQ-9), duration of respiratory symptoms, and vital signs. Results In total, 128 patients completed the clinical trial. The QARP group and standard therapies group showed significant improvements in vital signs (except blood pressure) and clinical scales compared with baseline (p<0.05). The QARP group also showed more significant improvement in the mMRC dyspnea scale (-1.8 [-2.1, -1.6], p=0.018) and modified Borg dyspnea scale (-3.7 [95% confidence intervals (CI) -4.3, -3.1], p=0.045). The duration of cough was 14.3 days (95% CI 12.6, 16.1, p=0.046), and the length of hospital stay was 18.5 days (95% CI 17.0, 20.0, p=0.042) in the QARP group, both of which were significantly reduced compared with the standard therapies group (p<0.05). Conclusion QARP plus standard therapies improved lung function and symptoms such as dyspnea and cough in patients with severe COVID-19 and shortened the length of hospital stay. Therefore, QARP may be considered an effective treatment option for patients with severe COVID-19.

Aims: The current study aims to elucidate the treatment efficacy (defined as undetectable HCV RNA throughout 12 weeks of post-treatment follow-up, SVR12) and safety DCV/ASV plus ribavirin for 12 weeks in HCV-1b patients without NS5A RAS. Methods: This is a single-arm, open-label phase 2 study. Seventy directly acting antivirals (DAA)-naïve HCV-1b patients without L31/Y93 RAS are planned to receive daclatasvir (60 mg/ day) and asunaprevir (100 mg twice daily) plus weight-based ribavirin (1000-1200 mg/day) for 12 weeks. After treatment they were followed up for 12 weeks. Results: As of 31 Oct 2017, 58 eligible patients are allocated to treatment, with a mean age of 59.3 years and female predominance (67.2%, 39/58). The mean HCV RNA was 5.87+0.77 log10 IU/mL; 23 patients (39.7 %) had significant hepatic fibrosis (>F2). In the modified intention-to-treat analysis, the rate of undetectable HCV at week 1, week 2, week 4, week 8 and endof- treatment was 25 % (14/56), 84.8 % (39/46), 100 % (46/46), 100 % (38/38) and 100 % (27/27), respectively. Undetectable HCV RNA were observed in all of the patients with HCV RNA assessable 4 weeks (SVR4, 18/18) and 12 weeks (SVR12, 12/12) post treatment. None of the 18 patients who completed the 12-week treatment experienced relapse during post-treatment follow-up. The most common adverse event was fatigue (78.3 %), followed by pruritus (65.2 %) and dizziness (52.2 %), of which were considered as ribavirin related. None of the participating subjects withdrew treatment or follow-up throughout the trial peroid. Three serious adverse events were reported which included urosepsis, appendicitis and left ureteral stone. All were unrelated to the investigating drugs. Conclusions: 12 weeks of DCV/ASV plus ribavirin was highly effective and safe in HCV-1b patients without NS5A RAS in the interim analysis. The satisfactory results would be anticipated in the full patient set.

Side effects are an unavoidable consequence of chemotherapy drugs, during which liver injury often takes place. The current study was designed to investigate the protective effect of Astragalus polysaccharides (APS) against the hepatotoxicity induced by frequently-used chemical therapy agents, cyclophosphamide (CTX), docetaxel (DTX) and epirubicin (EPI)) in mice. Mice were divided into five groups, controls, low or high dose groups ($DTX_L$, $CTX_L$, $EPI_L$ or $DTX_H$, $CTX_H$, $EPI_H$), and low or high dose chemotherapeutics+APS groups ($DTX_L$+APS, $CTX_L$+APS, $EPI_L$+APS or $DTX_H$+APS, $CTX_H$+APS, $EPI_H$+APS). Controls were treated with equivalent normal saline for 28 days every other day; low or high dose group were intraperitoneal (i.p) injected with low or high doses of CTX, DTX and EPI for 28 days every other day; low or high dose chemotherapeutics+APS group were separately intraperitoneal (i.p) injected with chemotherapeutics for 28 days every other day and i.p with APS (100 mg/kg) for 7 days continually from the 22th to the 28th days. The body weight, serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), histopathological features, and ultrastructure morphological change of liver tissues, protein expression level of caspase-3 were estimated at different time points. With high dose treatment of DTX, CTX and EPI, weight gain was inhibited and serum levels of ALT and AST were significantly increased. Sections of liver tissue showed massive hepatotoxicity in $CTX_H$ group compared to the control group, including hepatic lobule disorder, granular and vacuolar degeneration and necrosis in hepatic cells. These changes were confirmed at ultrastructural level, including obvious pyknosis, heterochromatin aggregation, nuclear membrane resolution, and chondrosome crystal decrease. Western blotting revealed that the protein levels of caspase-3 increased in $CTX_H$ group. The low dose groups exhibited trivial hepatotoxicity. More interestingly, after 100 mg/kg APS, liver injury was redecued not only regarding serum transaminase activities (low or high dose chemotherapeutics+APS group), but also from pathological and ultrastructural changes and the protein levels of caspase-3 ($CTX_H$+APS group). In conclusion, DTX, CTX and EPI induce liver damage in a dose dependent manner, whereas APS exerted protective effects.

The proliferation and migration of hepatic stellate cells (HSCs) profoundly impact the pathogenesis of liver inflammation and fibrogenesis. As a perennial herb native to China, Bupleurum falcatum is administered for its anti-inflammatory,antipyretic, and antihepatotoxic effects. Saikosaponin a (SSa) and Saikosaponin d (SSd) are the major active components of triterpene saponins in Bupleurum falcatum. This study analyzes how SSa and SSd affect rat HSC-T6 cell line proliferation and migration. Experimental results indicate that, in addition to suppressing HSC-T6 proliferation, wound healing activity and cell migration in a time- and dose-dependent manner, SSa and SSd significantly induce apoptosis. Additionally, SSa and SSd decreased the expressions of extracellular matrix-regulated kinase 1/2 (ERK1/2), platelet-derived growth factor receptor 1 (PDGFR1), and subsequently transforming growth factor-b1 receptor (TGF-b1R), a-smooth muscle actin, TGF-b1 and connective tissue growth factor. They also decreased phosphorylation of p38 (p-p38) and ERK1/2 (p-ERK1/2) of HSC-T6. Furthermore, both SSa and SSd can block PDGF-BB and TGF-b1-induced cell proliferation and migration of HSC-T6. These results suggest that SSa and SSd may inhibit proliferation and activation of HSC-T6, and the modulated mechanisms warrant further study.

Effects of light on phenolic compounds and antioxidant activities during germination of soybean seeds were studied. Soybean seeds were germinated in the presence and absence of light. Chlorophylls and morphological characteristics of sprouts were evaluated daily. Antioxidant activities were determined using 2,2-diphenyl-1-picryl-hydrazyl (DPPH) and ferric reducing activity power methods. Morphological characteristics of light-grown sprouts were superior to dark-grown sprouts and the metabolism of phenolic compounds was regulated by light. Light treatment improved accumulation of phenolic compounds in soybean sprouts and increased antioxidant activities. The optimum harvest time of light-grown sprouts was on the seventh day when sprouts achieved the best nutraceutical value. Green sprouts can serve as a good vegetable source for the human diet.

Free fatty acids (FFAs) are known to have bacteriocidal activity and are important components of the innateimmune system. Many FFAs are naturally present in human and animal skin, breast milk, and in the bloodstream. Here, the therapeutic potential of FFAs against methicillin-resistant Staphylococcus aureus (MRSA) is demonstrated in cultures and in mice. Among a series of FFAs, only oleic acid (OA) (C18:1, cis-9) can effectively eliminate Staphylococcus aureus (S. aureus) through cell wall disruption. Lauric acid (LA, C12:0) and palmitic acid (PA, C16:0) do not have this ability. OA can inhibit growth of a number of Gram-positive bacteria, including hospital and community-associated MRSA at a dose that did not show any toxicity to human sebocytes. The bacteriocidal activities of FFAs were also demonstrated in vivo through injection of OA into mouse skin lesions previously infected with a strain of MRSA. In conclusion, our results suggest a promising therapeutic approach against MRSA through boosting the bacteriocidal activities of native FFAs, which may have been co-evolved during the interactions between microbes and their hosts.

N-doped porous carbon-based materials (NPCMs) with hierarchical pore structures have beenconsidered to be a suitable alternative to meet the ever-increasing demands for supercapacitors;however, the universally low yield of the NPCMs has restricted their practical applications. Herein, aseries of NPCMs with hierarchical pore structures are synthesized with significantly increased yieldsthrough the carbonization of the copolymer made from 2,4,6-tris(chloromethyl)mesitylene and pphenylenediamine. The development of the hierarchical pore structures and the N content of the NPCMsshow opposite dependences on the increasing carbonization temperature. The NPCM exhibits the bestcapacitive ability only if the sufficiently developed hierarchical structures and moderate N content areachieved simultaneously. Therefore, NPCM-600 that is carbonized at 600 C with an excellent yield of53.6% (wt.), large specific surface area of 1778 m2 g 1, and N content of 4.13% (wt.) yields an ideal specificcapacitance of 298 F g 1 at the current density of 1 A g 1 and a perfect cycling stability of the capacitanceafter 10,000 cycles at 10 A g 1. The yield of the NPCM-600 is considerably higher than those for manyother recently reported NPCMs. NPCM-600 also shows better capacitance than those of the otherreported NPCMs, such as NOPC-bis-CN-3 (167 F g 1) and CHCPB-K-600 (260 F g 1).
