Abstract
Objectives: To find the prognostic factors related to early triple-negative breast cancer to optimize the therapeutic strategies, and explore the influence of programmed cell death ligand-1(PD-L1)expression in early triple-negative breast cancer on its prognosis, so as to provide support for clinical treatment decisions. Methods: Early triple-negative breast cancer patients treated at the National Cancer Center, National Clinical Research Center for Cancer, Cancer Hospital, Chinese Academy of Medical Sciences during 1st June, 2009 and 31st Oct, 2015 were enrolled in this study. All the clinicopathological data of patients were collected, and the paraffin sections of the surgical specimens were stained with estrogen receptor, progesterone receptor, human epidermal growth factor receptor-2, secreted protein acidic and rich in cysteine (SPARC), androgen receptor, PD-L1 and other antibodies by the immunohistochemical method. Kaplan-Meier survival and Cox regression curves were used for survival analysis of relevant clinical and pathological results and nomogram survival prediction models were established to explore the influence of relevant factors on the prognosis. Results: A total of 205 patients with triple-negative breast cancer were enrolled. Ninety patients (43.9%) were PD-L1 positive. The median follow-up time was 63 months. Thirty-seven patients were relapsed or recurrent and 16 patients were dead. The 5-year disease-free survival (DFS) rate and overall survival (OS) rate were 86.1% (95% CI: 81.4%-90.8%) and 93.6% (95% CI: 91.0%-97.6%), respectively, in the general population. Univariate Cox regression analysis showed that PD-L1 expression and lymph node metastasis were correlated with DFS and OS (P<0.05). In multivariate analysis, PD-L1 expression was an independent influencing factor of DFS, with PD-L1 positive patients possessing a significant survival benefit in DFS (HR=0.31, 95% CI: 0.13-0.73). Lymph node metastasis was an independent influencing factor of OS, and OS was significantly shortened in patients with positive lymph node metastasis (HR=3.24, 95% CI: 1.15-9.17). PD-L1, lymph node metastasis, menopausal status, Ki-67 index and adjuvant chemotherapy regimen were included to establish the 1- and 3-year DFS and OS nomogram prediction models, resulting in C indices of 0.698 and 0.748, respectively. Conclusions: PD-L1 expression is a predictive biomarker of good prognostic factor in triple-negative breast cancer patients. DFS is significantly prolonged in PD-L1 positive patients and OS also shows a prolongation trend. The nomogram prognosis prediction models have reference values for adjuvant chemotherapy in this patient group.

Abstract
Swertia bimaculata (SB) is a medicinal herb in China having an array of therapeutic and biological properties. This study aimed to explore the attenuating effect of SB on carbon tetrachloride (CCl4) induced hepato-toxicity by regulation of gut microbiome in ICR mice. For this purpose, CCl4 was injected intraperitoneally in different mice groups (B, C, D and E) every 4th day for a period of 47 days. Additionally, C, D, and E groups received a daily dose (50 mg/kg, 100 mg/kg, and 200 mg/kg respectively) of Ether extract of SB via gavage for the whole study period. The results of serum biochemistry analysis, ELISA, H&E staining, and sequencing of the gut microbiome, indicated that SB significantly alleviates the CCl4-induced liver damage and hepatocyte degeneration. The serum levels of alanine transaminase, aspartate aminotransferase, malondialdehyde, interleukin 1 beta and tumor necrosis factor-alpha were significantly lower in SB treated groups compared to control while levels of glutathione peroxidase were raised. Also, the sequencing data indicate that supplementation with SB could restore the microbiome and its function in CCl4-induced variations in intestinal microbiome of mice by significantly downregulating the abundances of pathogenic intestinal bacteria species including Bacteroides, Enterococcus, Eubacterium, Bifidobacterium while upregulating the levels of beneficial bacteria like Christensenella in the gut. In conclusion, we revealed that SB depicts a beneficial effect against hepatotoxicity induced by CCl4 in mice through the remission of hepatic inflammation and injury, through regulation of oxidative stress, and by restoring gut microbiota dysbiosis.

Abstract
Chlorogenic acid (CA) and sodium alginate (SA) each have good therapeutic effects on ulcerative colitis (UC) owing to their antioxidant and anti-inflammatory activity. This study aimed to investigate the effects of CA alone and in combination with SA on inflammatory cells and UC mice. In the Lipopolysaccharide (LPS)-induced RAW 264.7 inflammatory cell model, Nitric oxide (NO) and interleukin-6 (IL-6) levels were significantly lower after treatment with CA plus SA than with CA alone. In the DSS-induced UC mouse model, compared with CA alone, CA plus SA showed a better ability to alleviate weight loss, reduce the disease activity index (DAI), improve the colonic mucosa, reduce the expression of inflammatory factors in the serum and myeloperoxidase (MPO) in colonic tissue, increase superoxide dismutase (SOD) levels, protect the intestinal mucosa and regulate the abundance of Actinobacteriota, Lactobacillus, Bifidobacterium, Bacteroides, Subdoligranulum and Streptococcus. Thus, CA plus SA can improve the therapeutic efficacy of CA in UC by regulating inflammatory factors, oxidative stress, and the intestinal flora and by protecting ulcerative wounds. These findings broaden our understanding of the role of the combination of SA and CA in enhancing the effects of CA on UC and provide strategies for prevention and treatment.

Abstract
This study investigated the therapeutic effects and mechanisms of chitosans (CSs) with different molecular weights on ulcerative colitis (UC). Three size classes of CSs (Mw ≤ 3, 50, and 200 kDa) were used in this study. The effect of large CSs (Mw ≤ 200 kDa) on UC was the best, followed by that of medium CSs (Mw ≤ 50 kDa), and that of small CSs (Mw ≤ 3 kDa) was the least in the LPS-induced Raw 264.7 cell model and DSS-induced UC mice model. The therapeutic mechanisms of three CSs are related to anti-oxidation, anti-inflammation, and regulation of immunoglobulin and intestinal flora by attenuating body weight loss, decreasing the disease activity index (DAI) and MPO activity, suppressing proinflammatory cytokines and IgG levels, down-regulating the level of oxidative stress, increasing anti-inflammatory cytokines, SOD activity and Prevotellaceae_UCG-001 levels, and reducing the abundance of Proteobacteria, Actinobacteria, and Escherichia-Shigella. In general, the molecular weight of CSs influences their efficacy against UC. CSs with an optimal molecular weight demonstrate good development prospects for ameliorating UC.

Abstract
A new isoflavonoid, xanthocerin J, along with previously described xanthocerin A, were isolated from a methanol extract of aerial parts of a traditional American Indian herb, Amorpha canescens Pursh (Asteraceae). The structures of these compounds were characterized using mass spectrometry and NMR based on an isolation protocol using magnetic microbead affinity selection screening (MagMASS) for ligands to the estrogen receptor alpha (ERα). These compounds bound to ERα from an active fraction that exhibited dose-dependent antiestrogenic activity in the in vitro Ishikawa assay. However, these compounds did not exhibit antiestrogenic activity in the cell-based Ishikawa assay. Xanthocerin A and J may exhibit synergistic or additive activity with other compounds found in A. canescens which needs further exploration. This work highlights the potential of A. canescens as a prospect for the future discovery of compounds for women's health related to estrogen pathways.

Abstract
Objective: To assess the therapeutic efficacy and safety of the gemcitabine combined with nedaplatin (GN) chemotherapy for metastatic human epidermal growth factor receptor-2 (HER-2) negative breast cancer patients. Methods: Forty-five patients with HER-2 negative recurrent metastatic breast cancer who had received prior adjuvant or neoadjuvant therapy with anthracycline and/or taxanes were enrolled. All the patients received GN regime from January 2014 to February 2019. The therapeutic efficacy was evaluated according to response evaluation criteria in solid tumors (RECIST) 1.1. The adverse response was evaluated and monitored according to common terminology criteria for adverse events (CTCAE). The progression-free survival (PFS) and overall survival (OS) and prognostic factors were also analyzed. Results: All of the 45 patients received 4 course GN, 1 of them achieved complete response, 21 achieved partial response. The objective response rate was 48.9 (95% CI: 33.7%-64.1%). Grade 3-4 hematological toxicities include leukopenia occurred in 10 (22.2%) of patients, neutropenia in 13 (28.9%) patients, and thrombocytopenia in 8 (17.6%) patients. The grade 3-4 hematological toxicities mainly manifested as nausea and vomiting, and the incidence was 4.4% (2/45). Among the 45 patients, 34 died, the median PFS was 5.1 (95% CI: 3.9-6.1) months and the median OS was 17.6 (95% CI: 13.1-20.9) months. Conclusion: The combination of gemcitabine and nedaplatin is an effective and tolerable treatment for metastatic breast cancer patients previously treated with anthracyclines and/or taxanes.

Abstract
The incidence of ulcerative colitis (UC) is high. Despite the availability of various therapeutic agents for the treatment of UC, the routine treatment has limitations and serious side effects. Therefore, a new drug that safely and effectively treats UC is urgently needed. Polysaccharides from natural resources have recently become a hot topic of study for their therapeutic effects on UC. These effects are associated with the regulation of inflammatory cytokines, intestinal flora, and immune system and protection of the intestinal mucosa. This review focuses on the recent advances of polysaccharides from natural resources in the treatment of UC. The mechanisms and practicability of polysaccharides, including pectin, guar gum, rhamnogalacturonan, chitosan, fructan, psyllium, glycosaminoglycan, algal polysaccharides, polysaccharides from fungi and traditional Chinese medicine, and polysaccharide derivatives, are discussed in detail. The good efficacy and safety of polysaccharides make them promising drugs for treating UC.

Abstract
Non-alcoholic fatty liver disease is chronic steatosis of the liver in children and adolescents under 18 years of age, which is related to insulin resistance, obesity and dyslipidemia. Non-alcoholic fatty liver is the most common cause of liver disease in children, and lifestyle interventions such as diet or exercise are usually recommended as a treatment. Compared with dietary restriction that may affect growth and development, physical training has become the main form of treatment for children with non-alcoholic fatty liver disease. This article summarizes the aspects of physical training intervention for non-alcoholic fatty liver disease in children.

Abstract
Objective: To investigate the fertility needs and outcome of pregnancy in patients with young breast cancer in China. Methods: A retrospective cross-sectional investigation was conducted on 374 young breast cancer women from Cancer Hospital, Chinese Academy of Medical Sciences. Young patients with breast cancer were defined as patients who got initial diagnosis of breast cancer at age no more than 40 years old. We conducted a questionnaire survey and collected clinical data from medical chart. Logistic regression model was used to analyze the possible factors influencing patients' fertility intention. Results: 308 young women with breast cancer completed questionnaires, and the response rate was 82.4%. 81 patients (26.3%) had fertility needs after diagnosis. Of them, 6 cases took active measures to preserve fertility. 72 patients (23.4%) received fertility counseling during treatment. 7 patients were successfully pregnant, including four cases who delivered normally. Multivariate logistic regression analysis showed that patients under 35 years old (OR=4.81), bachelor degree or above (OR=3.26), receiving breast-conserving surgery (OR=2.15) and childless patients (OR=3.03) were more likely to have fertility needs after diagnosis of breast cancer (all P<0.05). Conclusions: The fertility needs of young breast cancer women in China are gradually increasing. Healthcare providers associated with tumor patients should actively offer corresponding fertility consultation and individualized diagnosis and therapy plans for patients with fertility needs.

Abstract
Background Targeted prodrug has various applications as drug formulation for tumor therapy. Therefore, amphoteric small-molecule prodrug combined with nanoscale characteristics for the self-assembly of the nano-drug delivery system (DDS) is a highly interesting research topic. Methods and Results In this study, we developed a prodrug self-assembled nanoplatform, 2-glucosamine-fluorescein-5(6)-isothiocyanate-glutamic acid-paclitaxel (2DA-FITC-PTX NPs) by integration of targeted small molecule and nano-DDS with regular structure and perfect targeting ability. 2-glucosamine (DA) and paclitaxel were conjugated as the targeted ligand and anti-tumor chemotherapy drug by amino acid group. 2-DA molecular structure can enhance the targeting ability of prodrug-based 2DA-FITC-PTX NPs and prolong retention time, thereby reducing the toxicity of normal cell/tissue. The fluorescent dye FITC or near-infrared fluorescent dye ICG in prodrug-based DDS was attractive for in vivo optical imaging to study the behavior of 2DA-FITC-PTX NPs. In vitro and in vivo results proved that 2DA-FITC-PTX NPs exhibited excellent targeting ability, anticancer activity, and weak side effects. Conclusion This work demonstrates a new combination of nanomaterials for chemotherapy and may promote prodrug-based DDS clinical applications in the future.

Abstract
Streptococcus iniae is a pathogenic and zoonotic bacterium responsible for human diseases and mortality of many fish species. Recently, this bacterium has demonstrated an increasing trend for antibiotics resistance, which has warranted a search for new approaches to tackle its infection. Glutamate racemase (MurI) is a ubiquitous enzyme of the peptidoglycan synthesis pathway that plays an important role in the cell wall integrity maintenance; however, the significance of this enzyme differs in different species. In this study, we knocked out the MurI gene in S. iniae in order to elucidate the role of glutamate racemase in maintaining cell wall integrity in this bacterial species. We also cloned, expressed, and purified MurI and determined its biochemical characteristics. Biochemical analysis revealed that the MurI gene in S. iniae encodes a functional enzyme with a molecular weight of 30 kDa, temperature optimum at 35°C, and pH optimum at 8.5. Metal ions, such as Cu2+, Mn2+, Co2+ and Zn2+, inhibited the enzyme activity. MurI was found to be essential for the viability and cell wall integrity of S. iniae. The optimal growth of the MurI-deficient S. iniae mutant can be achieved only by adding a high concentration of D-glutamate to the medium. Membrane permeability assay of the mutant showed an increasing extent of the cell wall damage with time upon D-glutamate starvation. Moreover, the mutant lost its virulence when incubated in fish blood. Our results demonstrated that the MurI knockout leads to the generation of S. iniae auxotroph with damaged cell walls.

Abstract
Purpose: We aimed to prepare two oral drug delivery systems consisting of polyoxyl 15 hydroxystearate (HS15) with pluronicF127 (F127) and HS15 with pluronicL61 (L61) to overcome the challenges of genistein’s poor oral bioavailability. This provides a good strategy for enhancing the potential value of genistein. Methods: We designed two binary mixed micelle systems employing the organic solvent evaporation method using surfactants (HS15, L61, and F127). Formulations (GEN-F and GEN-L) were characterized by transmission electron microscopy. Drug content analysis, including entrapment efficiency (EE%), drug loading (DL%), and the cumulative amount of genistein released from the micelles, was performed using HPLC. The permeability of optimum formulation was measured in Caco-2 cell monolayers, and the oral bioavailability was evaluated in SD rats. Results: The solutions of GEN-F and GEN-L were observed to be transparent and colorless. GEN-F had a lower EE% of 80.79±0.55% and a DL% of 1.69±0.24% compared to GEN-L, which had an EE% 83.40±1.36% and a DL% 2.26±0.18%. TEM results showed that the morphology of GEN-F and GEN-L was homogeneous and resembled a spherical shape. The dilution and storage conditions had no significant effect on particle size and EE%. Genistein demonstrated a sustained release behavior when encapsulated in micelles. Pharmacokinetics study showed that the relative oral bioavailability of GEN-F and GEN-L increased by 2.23 and 3.46 fold while also enhancing the permeability of genistein across a Caco-2 cell monolayer compared to that of raw genistein. Conclusion: GEN-F and GEN-L as a drug delivery system provide an effective strategy for enhancing and further realizing the potential value of GEN.

Abstract
Chronic glomerulonephritis frequently develops into renal failure that cannot be completely cured. Based on the success of anti-inflammatory Chinese herbs in treating chronic nephritis, our goal was to investigate the therapeutic effects and mechanism of action of loquat leaf polysaccharides (LLPS) on chronic anti-Thy-1 nephritis. A rat model of glomerulonephritis was used to study the effects of 8 weeks of enalapril or LLPS treatment. Twenty-four-hour rat urinary protein excretions were measured every week for 8 weeks. Then, all animals were sacrificed, renal-related biochemical parameters were analyzed, and histology and electron microscopy examinations of renal tissue samples were conducted. Renal cortex tissue was used to detect markers of renal fibrosis. RNA sequencing (RNA-seq) and in vitro experiments explored the signaling pathway involved in LLPS treatment effects. Compared with the disease control group, LLPS treatment significantly decreased the levels of serum creatinine and blood urea nitrogen, reduced urinary protein excretion, glomerular mesangial cell proliferation, and extracellular matrix hyperplasia, and attenuated the expression of proteins associated with podocyte injury and renal fibrosis. RNA-seq results showed that peroxisome proliferator-activated receptor (PPAR) is a potential signaling pathway involved in LLPS treatment of chronic glomerulonephritis. Increases in PPARα and plasminogen activator inhibitor-1 (PAI-1) caused by glomerulonephritis were inhibited by LLPS in vitro. Furthermore, when an agonist of PPARα (BMS-687453) was used to stimulate PPARα activity, LLPS treatment suppressed the expression of fibrosis factor PAI-1 partially via PPARα inhibition. These findings demonstrate that LLPS improved glomerular injury in rats with anti-Thy 1 nephritis via the PPARα pathway.

Abstract
OBJECTIVES To increase the solubility of baicalein (BAI) by preparing BAI-micelles (BAI-M) with Solutol HS15 (HS15) and Poloxamer 188 (F68), thereby improving its oral bioavailability. METHODS Baicalein micelles were prepared with HS15 and F68 by thin-film dispersion method and optimized by central composite design (CCD) approach. Physicochemical, in vitro release, Caco-2 cell transport and pharmacokinetic studies of BAI-M were performed. KEY FINDINGS The optimal formulation showed spherical shape by characterization of the transmission electron microscope with average small size (23.14 ± 1.46 nm) and high entrapment efficiency (92.78±0.98%) and drug loading (6.45±1.54%). The in vitro release study of BAI-M showed a significantly sustained release pattern compared with free BAI. Caco-2 cell transport study demonstrated that high permeability of BAI was achieved after loading it into micelles. Meanwhile, pharmacokinetics study of BAI-M showed a 3.02-fold increase in relative oral bioavailability compared with free BAI. CONCLUSIONS Based on our findings, we concluded that HS15 can be used as a carrier in this drug delivery system that includes F68, and BAI-M has great potential in improving solubility and oral bioavailability.

Abstract
The aim of this study was to prepare two novel magnolol (MO)-loaded binary mixed micelles (MO-M) using biocompatible copolymers of Soluplus (SOL) and Solutol® HS15 (HS15), SOL and d-alpha-tocopheryl polyethylene glycol 1000 succinate (TPGS), to improve magnolol's poor solubility and its oral bioavailability. The organic solvent evaporation method was used to obtain two MO-M by optimization; one was prepared by using SOL and HS15 (MO-H), and the other was prepared by using SOL and TPGS (MO-T). The entrapment efficiency (EE%) and drug loading (DL%) of MO-T were 94.61 ± 0.91% and 4.03 ± 0.19%, respectively, and the MO-H has higher EE% and DL% (98.37 ± 1.23%, 4.12 ± 0.16%). TEM results showed that the morphology of MO-M was homogeneous and was spherical in shape. The dilution stability of MO-M did not undergo significant changes. Permeability of MO-M across a Caco-2 cell monolayer was enhanced in Caco-2 cell transport models. The pharmacokinetics study showed that the relative oral bioavailability of MO-T and MO-H increased by 2.39- and 2.98-fold, respectively, compared to that of raw MO. This indicated that MO-H and MO-T could promote absorption of MO in the gastrointestinal tract. Collectively, the mixed micelles demonstrated greater efficacy as a drug delivery system. The development of these novel mixed micelles is valuable for resolving the poor solubility and bioavailability of drugs.

Abstract
Reciprocity is a fundamental property of the wave equation in a linear medium that originates from time-reversal symmetry, or T symmetry. For electromagnetic waves, reciprocity can be violated by an external magnetic field. It is much harder to realize nonreciprocity for acoustic waves. Here we report the first experimental observation of linear nonreciprocal transmission of ultrasound through a water-submerged phononic crystal consisting of asymmetric rods. Viscosity of water is the factor that breaks the T symmetry. Asymmetry, or broken P symmetry along the direction of sound propagation, is the second necessary factor for nonreciprocity. Experimental results are in agreement with numerical simulations based on the Navier-Stokes equation. Our study demonstrates that a medium with broken PT symmetry is acoustically nonreciprocal. The proposed passive nonreciprocal device is cheap, robust, and does not require an energy source.

Abstract
OBJECTIVES We aimed to prepare novel magnolol-loaded mixed micelles (MAG-M) by pluronic F127 and L61 to overcome the challenges of magnolol's poor solubility and then further improve its oral bioavailability. METHODS Magnolol-loaded mixed micelles containing pluronic F127 and L61 were prepared by an organic solvent evaporation method. Physicochemical, transport experiment across Caco-2 cell monolayers and pharmacokinetic studies were performed to characterize MAG-M and to determine the final improvement of the oral bioavailability. KEY FINDINGS The MAG-M solution was transparent and colourless with average size, polydispersity index and zeta potential of 228.0 ± 2.1 nm, 0.298 ± 0.012 and -0.89 ± 0.02 mV. The micelle solution has a higher EE% and DL% of 81.57 ± 1.49% and 27.58 ± 0.53%, respectively. TEM result showed that the morphology of MAG-M was homogeneous and spherical shape. The dilution stability of MAG-M was no significant change in particle size and entrapment efficiency. MAG was demonstrated a sustained-release behaviour after encapsulated in micelles. MAG permeability across a Caco-2 cell monolayer was enhanced, and the pharmacokinetics study of MAG-M showed a 2.83-fold increase in relative oral bioavailability compared with raw MAG. CONCLUSIONS The mixed micelles containing pluronic F127 and L61 as drug delivery system provided a well strategy for resolving the poor solubility and bioavailability problems of MAG.

Abstract
Objective:To provide evidence and strategy for treatment of very old patients with benign paroxysmal positional vertigo (v-BPPV) by retrospective analysis of v-BPPV patients. Method:According to the criteria, 19 v-BPPV patients were collected, aging from 80 to 91 years old, including 10 horizontal semicircular canal BPPV (HC-BPPV), 4 posterior semicircular canal (PC-BPPV) and 5 mutiple semicircular canal BPPV patients. PC-BPPV patients were treated by Epley or Li maneuver, and HC-BPPV patients were treated by Barbecue or Li maneuver. Each patient was treated twice, with an interval of 5 to 10 minutes. Result:Rates of 3-day cure and efficacy were 63.16% and 94.74%, respectively. Rates of 1-week cure and efficacy were 89.47% and 100.00%, respectively. Conclusion:v-BPPV can have good outcomes via proper treatment. Age should not influence BPPV outcomes, while we should pay more attention to v-BPPV patients' physiclal status and systematic diseases which may increase risk to diagnosis and treatment.

Abstract
Abstract
Objectives
With the purpose of developing a curcumin phospholipid complex (CPC) formulation with high performance, the CPC was prepared and solidified with Soluplus® in this study.
Methods
Soluplus® was used as a carrier to solidify CPC. The structures of the CPC and curcumin phospholipid complex – Soluplus® solidified powder (CSP) – were also characterized by differential scanning electron microscope, differential scanning calorimetry, Fourier transform infrared spectroscopy and X-ray diffractometer, and flowability, in-vitro dissolution and oral bioavailability were also investigated.
Key findings
All analysis indicated that curcumin was completely converted from crystalline to amorphous state in solidified powder. The angle of repose calculated in flowability study indicated a marked improvement from ‘cannot be measured’ to ‘37°’. Meanwhile, the dissolution study showed that in phosphate buffer condition, the dissolution rate of CSP had released 76.34% in pH 6.8 and the 78.19% in pH 1.2. Furthermore, in pharmacokinetic study, significant (P < 0.01) improvement of AUC0–∞ value was observed between CPC and CSP groups, and the results showed that AUC0–∞ value was increased from 205.84 ± 50.46 μg h/ml to 330.47 μg h/ml.
Conclusions
A simple and convenient solidifying process was used in this study, and the data suggested that this process not only could improve the flowability and dissolution of phospholipid complex, but also increased the oral bioavailability of curcumin.

Abstract
Oxidative stress plays an important role in the development of diabetic cardiomyopathy. In the present study, we determined whether the effect of astragalus polysaccharides (APS) on diabetic cardiomyopathy was associated with its impact on oxidative stress. Streptozotocin (STZ)-induced diabetic mice and heterozygous superoxide dismutase (SOD2+/-) knockout mice were administered APS. The hemodynamics, cardiac ultrastructure, and the apoptosis, necrosis and proliferation of cardiomyocytes were assessed to evaluate the effect of APS on diabetic and oxidative cardiomyopathy. Furthermore, H2O2 formation, oxidative stress/damage, and SOD activity in cardiomyocytes were evaluated to determine the effects of APS on cardiac oxidative stress. APS therapy improved hemodynamics and myocardial ultrastructure with reduced apoptosis/necrosis, and enhanced proliferation in cardiomyocytes from both STZ-induced diabetic mice and heterozygous SOD2+/- knockout mice. In addition, APS therapy reduced H2O2 formation and oxidative stress/damage, and enhanced SOD activity in both groups of mice. Our findings suggest that APS had benefits in diabetic cardiomyopathy, which may be partly associated with its impact on cardiac oxidative stress.

Abstract
BACKGROUND/OBJECTIVES This systematic review and meta-analysis was performed to assess the effects of inulin-type fructans (ITF) on human blood lipids and glucose homeostasis associated with metabolic abnormalities, including dyslipidemia, overweight or obesity, and type-2 diabetes mellitus (T2DM). SUBJECTS/METHODS The MEDLINE, EMBASE and Cochrane Library databases were systematically searched for randomized controlled trials (RCTs) before January 2016. Human trials that investigated the effects of ITF supplementation on the lipid profile, fasting glucose and insulin were included using Review Manager 5.3. RESULTS Twenty RCTs with 607 adult participants were included in this systematic review and meta-analysis. In the overall analysis, the supplementation of ITF reduced only the low density lipoprotein-cholesterol (LDL-c) (mean difference (MD): -0.15; 95% confidence interval (CI): -0.29, -0.02; P=0.03) without affecting the other endpoints. Within the T2DM subgroup analysis, ITF supplementation was positively associated with a decreased fasting insulin concentration (MD: -4.01; 95% CI: -5.92, -2.09; P<0.0001) and increased high density lipoprotein-cholesterol (HDL-c) (MD: 0.07; 95% CI: 0, 0.14; P=0.05). Moreover, a reduced fasting glucose tendency was identified only in the T2DM subgroup (MD: -0.42; 95% CI: -0.90, 0.06; P=0.09). There was a potential publication bias, and few trials were available for the T2DM subgroup analysis. CONCLUSIONS In summary, the use of ITF may have benefits for LDL-c reduction across all study populations, whereas HDL-c improvement and glucose control were demonstrated only in the T2DM subgroup. Thus, additional, well-powered, long-term, randomized clinical trials are required for a definitive conclusion. Overall, ITF supplementation may provide a novel direction for improving the lipid profile and glucose metabolism.

Abstract
UNLABELLED The purpose of this report was to retrospectively review the results of reconstruction of the thumb by use of combined two foot flaps with an iliac bone graft. From 2009 to 2014, nine patients with traumatic amputation of the thumb had their thumbs reconstructed. The two flaps were based on one pedicle. All flaps survived completely. Patients were followed for a mean of 15.6 months (range, 6-35 months). The appearance of the reconstructed thumb was comparable to a normal one, except for one thumb which required debulking. The appearance of the nail was satisfactory without deformity. The range of joint motion was satisfactory. The two point discrimination of the pulp ranged from 6 mm to >15 mm. The Michigan Hand Questionnaire outcome score was a mean of 76.2 ± 11.3 points and the Maryland foot rating score a mean of 94.8 ± 3.4 points. The combined two foot flaps with iliac bone graft might provide an option for the reconstruction of the thumb. LEVEL OF EVIDENCE III.

Abstract
Polymorphism (variable number of tandem repeats) in the second intron of the interleukin-1 receptor antagonist ( IL-1Ra) gene and two single nucleotide polymorphisms at positions −511 and +3954 of the IL-1β gene may be associated with an increased risk of rheumatoid arthritis (RA). This study used sex stratification to investigate a correlation of the three genetic polymorphisms with the risk of RA, on patients with RA and healthy controls. Polymerase chain reaction (PCR) and polymerase chain reaction–restriction fragment length polymorphism (PCR–RFLP) were performed. The frequencies of the IL-1β+ 3954 allele and genotype in female patients were significantly different compared with the controls; but in males, only the frequency of the IL-1β+ 3954 allele was different. The frequency of the IL-1RN genotype in patients was not statistically different compared with the controls; however, the frequency of IL-1RN allele in female patients was different. The association of the three polymorphisms with the susceptibility to RA appears to be significantly affected by gender.

Abstract
This paper provides a method for microscale fiber spinning and the in situ construction of a 3D fibrous scaffold on a single microfluidic platform. This platform was also used to fabricate a variety of fibrous scaffolds with diverse compositions without the use of complicated devices. We explored the potential utility of the fibrous scaffolds for tissue engineering applications by constructing a fibrous scaffold encapsulating primary hepatocytes. The cells in scaffold were cultured over seven days and maintained higher viability comparing with 3D alginate non-fibrous block. The main advantage of this platform is that the fibrous structure used to form a scaffold can be generated without damaging the mechanically weak alginate fibers or encapsulated cells because all procedures are performed in a single platform without the intervention of the operator. In addition, the proposed fibrous scaffold permitted high diffusion capability of molecules, which enabled better viability of encapsulated cells than non-fibrous scaffold even in massive cell culture.

Abstract
Weikang Keli (constitutes of Root of Codonopsis pilosula, Rhizoma Atractylodis Macrocephalae, Rhizoma Curcumae Aeruginosae, Rhizoma Pinelliae, Actinidia chinensis Planch, and Rhodiola rosea) is a well known Chinese herbal formula for gastric cancer therapy in clinical treatment. However, the detailed molecular mechanisms involved are still not fully understood. In this study, we found that Weikang Keli could induce patterns of autophagy in SGC-7901 cells, including intracellular vacuole formation, microtubule-associated protein 1 light chain 3 (LC3) conversion. Hoechst 33258 staining and Western blot analysis of apoptosis-related proteins showed that WK induced SGC-7901 cell death was not through apoptosis. In vivo study also revealed that i.g. administration of Weikang Keli once a day for 25 days could significantly reduce tumor volumes by about 50%. Collectively, the current data indicated that Weikang Keli induced gastric cancer cell death by autophagy effects.

Abstract
Toosendanin (TSN), a triterpenoid isolated from Melia toosendan Sieb. et Zucc., has been found to suppress proliferation and induce apoptosis in a variety of human cancer cells. However, the mechanism how TSN induces apoptosis remains poorly understood. In this study, we examined the effects of TSN on the growth, cell cycle arrest, induction of apoptosis and the involved signaling pathway in human promyelocytic leukemia HL-60 cells. Proliferation of HL-60 cells was inhibited in a dose-dependent manner with the IC(50 (48 h)) of 28 ng/mL. The growth inhibition was due primarily to the S phase arrest and cell apoptosis. Cell apoptosis induced by TSN was confirmed by Annexin V-FITC/propidium iodide staining. The increase of the pro-apoptotic protein Bax, cleaved PARP and caspase-3, and the decrease of anti-apoptotic protein Bcl-2 were observed. Western blot analysis indicated that TSN inhibits the CDC42/MEKK1/JNK pathway. Taken together, our study suggested, for the first time, that the pro-apoptotic effects of TSN on HL-60 cells were mediated through JNK signaling pathway.

Abstract
The tumor suppressor gene p53 has been implicated in the regulation of epithelial–mesenchymal transition (EMT) and tumor metastasis by regulating microRNA (miRNA) expression. Here, we report that mutant p53 exerts oncogenic functions and promotes EMT in endometrial cancer (EC) by directly binding to the promoter of miR-130b (a negative regulator of ZEB1) and inhibiting its transcription. We transduced p53 mutants into p53-null EC cells, profiled the miRNA expression by miRNA microarray and identified miR-130b as a potential target of mutant p53. Ectopic expression of p53 mutants repressed the expression of miR-130b and triggered ZEB1-dependent EMT and cancer cell invasion. Loss of an endogenous p53 mutation increased the expression of miR-130b, which resulted in reduced ZEB1 expression and attenuation of the EMT phenotype. Furthermore, re-expression of miR-130b suppressed mutant p53-induced EMT and ZEB1 expression. Importantly, the expression of miR-130 was significantly reduced in EC tissues, and patients with higher expression levels of miR-130b survived longer. These data provide a novel understanding of the roles of p53 gain-of-function mutations in accelerating tumor progression and metastasis through modulation of the miR-130b–ZEB1 axis.

Abstract
Immune-mediated mechanisms have been implicated in liver pathogenesis and subsequent progression in hepatitis B virus (HBV) infection. Costimulatory molecules, the important regulators of immune responses, participate in the regulation of liver pathology in HBV infection. However, the role of B7-H3 (CD276, a new member of B7 family) in this process has not been investigated. In this study, we detected abundant soluble B7-H3 (sB7-H3) in the plasma of patients with chronic HBV infections. The increase of the plasma B7-H3 was associated with the progression of liver cirrhosis and accompanied by decreased expression of B7-H3 on hepatocytes. The identification analysis suggests that the plasma B7-H3 might be derived from the membrane-bound B7-H3 on hepatocytes. A functional study showed that immobilized (4Ig) B7-H3Ig fusion protein could inhibit TCR-induced proliferation and IFN-γ secretion of T cells, which could be partially blocked by soluble B7-H3flag fusion protein. These results suggest that the reduced expression of B7-H3 in the livers might temper the inhibition of T-cell responses mediated by B7-H3 expressed on hepatocytes and thus promote the hepatic inflammation and hepatitis progression in the chronic HBV-infected patients.

Abstract
BACKGROUND We recently showed that poly(ADP-ribose)polymerase-1 (PARP-1) may play a role in allergen (ovalbumin)-induced airway eosinophilia, potentially through a specific effect on IL-5 production. We also reported that while IL-5 replenishment promotes reversal of eosinophilia in lungs of PARP-1(-/-) mice, IL-4 or Immunoglobulin E replenishment do not, suggesting a potentially significant regulatory relationship between PARP-1 and IL-5. OBJECTIVE To explore the mechanism by which PARP-1 regulates IL-5 production and to determine how PARP-1 inhibition blocks allergen-induced eosinophilia. METHODS This study was conducted using a murine model of allergic airway inflammation and primary splenocytes. RESULTS PARP-1 knockout-associated reduction in IL-5 upon allergen exposure occurs at the mRNA level. Such an effect appears to take place after IL-4 receptor activation as PARP-1 inhibition exerted no effect on JAK1/JAK3 activation. Signal transducer and activator of transcription-6 (STAT-6) protein was severely downregulated in spleens of PARP-1(-/-) mice without any effect on mRNA levels, suggesting an effect on protein integrity rather than gene transcription. Interestingly, the degradation of STAT-6 in PARP-1(-/-) mice required allergen stimulation. Additionally, PARP-1 enzymatic activity appears to be required for STAT-6 integrity. The downregulation of STAT-6 coincided with mRNA and protein reduction of GATA-binding protein-3 and occupancy of its binding site on the IL-5 gene promoter. IL-4 was sufficient to induce STAT-6 downregulation in both PARP-1(-/-) mice and isolated splenocytes. Such degradation may be mediated by calpain, but not by proteasomes. CONCLUSION These results demonstrate a novel function of PARP-1 in regulating IL-5 expression during allergen-induced inflammation and explain the underlying mechanism by which PARP-1 inhibition results in IL-5 reduction.

Abstract
Abstract
Background and Objective: The intrinsic high false negative rate associated with intraoperative analysis of SLN may result in a second surgical procedure for the patient. We attempt to improve the intraoperative and the pathologic and molecular evaluation of SLN by utilizing novel immunobead methods for detection and assessment of tumor cell expression of Her2, CD44 and Muc1.
Methods: During the operation of breast cancer patients, gived sentinel lymph node biopsy firstly, and the SLN will each be divided in four quadrants, and two quadrants (B,C) will be brought to the pathologist for routine intraoperative analysis and further immunhistochemical (H&E and CK) examination often 2 mm thick sections of each quadrant.
The other (A,D) quadrants will be immediately mechanically disaggregated and filtered in order to remove stromal elements and cellular debris. The resulting cell suspension will be incubated with 4.5 µm magnetic beads coated with MOC31 antibody, and simultaneously with different nonmagnetic, fluorescent microparticles coated with either anti-Her2, anti-CD44, or anti-Muc1 by flow-cytometry.
Results: 62 cases from 2009.1 to 2009.9 in our hospital has been studied, and results as follows: 1. Immunomagnetic evaluation of alive tumor cells in SLNs is rapidly and easily performed using the MOC-31 antibody that binds to the vast majority of breast cancer cells. The novel technologies will demonstrate higher detection sensitivity (96%) and lower false negative rate (4.0%). 2. For the intraoperative frozen HE staining, the sensitivity was 68%, false negative rate was 32%; and for CK-IHC, the sensitivity was 76.0%, and the false negative rate was 24%. 3.To compare to standard intraoperative procedures and histopathologic techniques of analyzing the SLN to that of the novel approach, it could get higher sensitivity (96%vs 68%,P=0.023;96%vs76%,P=0.049), lower false negative rate (4%vs32% ,P=0.023;4%vs24%,P=0.049) and higher micrometastasis detection rate. 4.Expession of Her2,CD44 and Muc1 in SLN is 32.5%±2.2%,83.4± 4.1% and 86.6%±3.4%, and each has positively correlated with the expression of that in primary tumor (P<0.5).
Conclusion: Our novel approach that utilizing immunobead detection of metastatic breast cancer cells, and simultaneously characterize the isolated cells for membrane markers coated with antibodies targeting Her2, Muc1 or CD44 by flow-cytometry, has rapid speed and high accuracy. Compared to traditional HE and CK-IHC, it has higher sensitivity and lower false negative rate, and could be used more widely and easily. Expression of CD44, Her2 and Muc1 in sentinel lymph nodes were positively correlated with the expression of those in primary tumor. It is suggested that the three biomarkers above could predict metastasis of sentinel lymph nodes, and maybe direct treatment after operation.

Abstract
We investigate the phase sensitivity of the fundamental mode of hollow-core photonic bandgap fibers to strain and acoustic pressure. A theoretical model is constructed to analyze the effect of axial strain and acoustic pressure on the effective refractive index of the fundamental mode. Simulation shows that, for the commercial HC-1550-02 fiber, the contribution of mode-index variation to the overall phase sensitivities to axial strain and acoustic pressure are respectively approximately -2% and approximately -17%. The calculated normalized phase-sensitivities of the HC-1550-02 fiber to strain and acoustic pressure are respectively 1 epsilon(-1) and -331.6 dB re microPa(-1) without considering mode-index variation, and 0.9797 epsilon(-1) and -333.1 dB re microPa(-1) when mode-index variation is included in the calculation. The latter matches better with the experimentally measured results.

Abstract
2542 Background: Translational control plays a key role in resistance to anti-cancer drug treatment. MicroRNAs regulate gene expression at the post-transcriptional level, mainly by interacting with 3'-UTR of their mRNA targets. Methods: miR-215 was ectopically expressed by transient transfection in both human colon cancer cell lines and osteosarcoma cell lines. The impact of miR-215 on cell proliferation, cell cycle control, chemosensitivity and down stream targets were characterized. The expression of miR-215 in colorectal cancer specimens and normal adjacent tissues was quantified by real time-qRT-PCR analysis. Results: In this study, we discovered that miR-215 down-regulates the expression of both dihydrofolate reductase (DHFR) and thymidylate synthase (TS), two of the most important chemotherapeutic targets, in human osteosarcoma U-2 OS and colon cancer HCT-116 (wt-p53) cell lines. Cells with elevated miR-215 expression are more resistant to DHFR inhibitor methotrexate (MTX) or TS inhibitor Tomudex (TDX) treatment. Ectopically over-expressing miR-215 triggers reduced cell proliferation and increased G2 arrest, at least in part, through the induction of p53 and p21. miR-215 transfected cells with reduced proliferating phenotype were resist to MTX or TDX treatment due to deceased cell cycle in S phase. The expression of endogeneous miR-215 was highly elevated in CD133+/HI CD44+/HI colon cancer stem cells compared to CD133- CD44- colon cancer cells, suggesting that tumor stem cells may be avoiding cellular and DNA damage caused by chemotherapy with a reduced proliferating phenotype mediated by certain miRNAs such as miR-215. The elevated expression of miR-215 in colon cancer stem cells with slow proliferation rate and resistance to chemotherapy further supports the role of miR-215 in cell proliferation and chemotherapy resistance. Conclusions: miR-215 may have a unique potential as a novel therapeutic target and biomarker candidate in cancer. No significant financial relationships to disclose.

Abstract
OBJECTIVE To study dynamic change of total ginkgolic acids in Ginkgo biloba leaves of the different aged trees and different collecting seasons. METHOD The content of total ginkgolic acids in G. biloba leaves was determined by HPLC. A Alltima C18 (4.6 mm x 250 mm, 5 microm) and the mobile phase of methanol and 1% acetic acid (90:10) were used, the flow rate was 1.0 mL x min(-1), and the wavelength was 310 nm. The content were calculated with external standard method. RESULT The content of total ginkgolic acids in G. biloba leaves was in the range of 0.48% to 2.51% in different collecting seasons. The content reached maximum at the end of May and the beginning of June, and then declined gradually. In different aged trees, the content in the older ages was lower than that in the younger ages. CONCLUSION The results provide scientific basis for the collecting season of G. biloba leaves.

Abstract
In the basic dideoxy sequencing reaction, an oligonucleotide primer is annealed to a single-stranded DNA template and extended by DNA polymerase in the presence of four deoxyribonucleoside triphosphates (dNTPs), one of which is 35S-labeled. The reaction also contains one of four dideoxyribonucleoside triphosphates (ddNTPs), which terminate elongation when incorporated into the growing DNA chain. After completion of the sequencing reactions, the products are subjected to electrophoresis on a high-resolution denaturing polyacrylamide gel and then autoradiographed to visualize the DNA sequence. Three variations of the dideoxy sequencing procedure are currently in use and are presented in this unit. In the "labeling/termination" procedure, primer chains are initially extended and labeled in the absence of terminating ddNTPs, whereas in the traditional "Sanger" procedure, labeling and termination of primer chains occur in a single step. A recent variation of the dideoxy sequencing method is thermal cycle sequencing in which the reaction mixture, containing template DNA, primer, thermostable DNA polymerase, dNTPs, and ddNTPs, is subjected to repeated rounds of denaturation, annealing, and elongation steps. The resulting linear amplification of the sequencing products allows much less template DNA to be used and eliminates independent primer annealing and template denaturation steps, which are required for the labeling/termination or Sanger procedures. The use of automated fluorescent sequencers for four-color dideoxy DNA sequencing is also described in detail.

Abstract
13505 Background: Immunotoxins (ITs) has shown limited clinical success related to liver toxicity and development of anti-IT antibodies. To delay the immune response we tested combinations of ITs and the Cyclosporin A (CsA). we have shown that one IT, currently in a phase I/II clinical trial, acts by inducing apoptosis and protein synthesis inhibition, but gene expression analysis of IT treated cells has never been reported. Hence, we also studied changes in gene expression induced by ITs alone and the effects of adding (CsA) on both treatment efficacy and gene expression signature. Methods: Human MA-11 breast cancer cells were treated in vitro with antiEGFR- and antiEPCAM-based ITs alone and in combinations with CsA. Therapeutic efficay was assessed by MTS cell viability assay. Total RNA from untreated and treated cells was isolated and CodeLink Uniset Human 20 k Oligo Bioarray (GE Healthcare, Amersham Biosciences, NJ), containing approximately 20,289 gene probes, was used to generate gene expression profiles. Gene expression analysis was carried out using GeneSpring software version 7.2 using One-way ANOVA with p<0.05. Comparisons of gene list across different groups were performed using Venn Diagrams. Results: Combination therapy produced remarkable synergistic effects in MA-11 cells in vitro and in metastasis models in vivo. Moreover, in conventional rats receiving repeated injections of ITs and CsA the formation of anti-IT antibodies was virtually abrogated. Changes in gene expression profiles induced by the ITs alone and in combination with CsA were evaluated to elucidate the underlying molecular mechanisms for the synergistic effects. The ITs each induced specific changes in expression of some apoptosis-related genes but also fogenes in pathways unrelated to apoptosis and protein synthesis. The addition of CsA induced up- or down-regulation of a number of interesting non-immune-associated genes Conclusions: Important shortcomings for successful clinical use of ITs may be overcome by combination therapy with CsA. The possibility for further improvement is provided by results of gene profiling studies identifying therapy-induced genes belonging to different cell signaling pathways.

Abstract
13513 Background: MicroRNAs (miRNAs) are small non-cording RNAs (∼ 22 nucleotide) that regulate gene expression by suppressing their target mRNAs at post-transcriptional level. Previous studies from our group have identified a number of dis-regulated miRNAs due to the loss of p53 tumor suppressor in cancer cell lines. As part of the efforts to further investigate the in vivo biological significance of these miRNAs, the expression of both hsa-let-7g and hsa-miR-200c were investigated using formalin-fixed paraffin embedded (FFPE) colon cancer specimens to evaluate the potential correlation with chemosensitivity and tumorigenesis. Methods: Forty-six patients with recurrent or residual colon cancer lesion assessable were treated with 5-FU based antimetabolite S-1. This includes twenty-one pair of tumor and normal samples. Total RNAs were isolated from these samples FFPE specimens (contains either > 90% normal or > 90% tumor tissue). cDNAs were synthesized using primers specific for hsa-let-7g, hsa-miR-200c and internal control 5S. The expression levels of each particular miRNAs were quantified using real time qRT-PCR analysis. The expression level of each miRNAs was quantified by measuring the difference of threshold cycle (CT) of candidate miRNAs and internal control 5S (Δ-CT). Results: The expression level of hsa-let-7g was significantly higher in tumor tissues compare to normal tissues (p=0.0026; Wilcoxon test). In the forty-six tumor tissues, the expression level of hsa-let-7g in disease response group (patients group of complete response, partial response and no change after chemotherapy) was significantly lower than the disease progression group (p=0.03; Mann-Whitney test). The expression of hsa-miR-200c was significantly over-expressed in tumor tissues compare to normal tissues (p=0.0001; Wilcoxon test). Although hsa-let-7g is strongly associated with patient’s response to S-1 treatment, it is not a prognostic factor for predicting survival. Conclusion: hsa-let-7g and hsa-miR-200c may be associated with tumorigenesis in colon cancer. In addition, hsa-let-7g may be a significant indicator for chemoresponse to S-1 based chemotherapy. No significant financial relationships to disclose.
