Abstract
1. This study focused on the relationship between MITF mRNA expression and plumage colour in quail and the effect of promoter methylation on the expression of MITF mRNA.2. The CDS region of MITF mRNA was cloned by RT-PCR, followed by DNA sequencing. The RT-qPCR method was used to analyse the expression levels of MITF mRNA in dorsal skin tissue in Korean quail and Beijing white quail. The promoter region of the MITF gene was cloned, and the CpG island was predicted by the CpGplot program. The methylation levels of the CpG island were analysed using BS-PCR technology.3. Quail MITF mRNA contains a 1,476 bp complete ORF, which encodes a 492 amino acid residue protein. The MITF protein has no signal peptide or transmembrane region. The expression of MITF mRNA in dorsal tissue of Korean quail was significantly higher than that in Beijing white quail (p < 0.01). Abundant cis-elements and a 346 bp CpG island were found in the promoter region of the MITF gene. The average methylation level of the CpG island was 22 (22%) in Korean quail, and 46 (30%) in Beijing white quail (p < 0.05).4. The hypermethylation of the MITF gene promoter region in Beijing white quail resulted in a decrease in expression level, which was related to white feather colour.

Abstract
Modern Bai Jiu(liquor) was called Shao Jiu in ancient times.By consulting ancient books, it was found that there was a distillation and preparation process of Shao Jiu before the Ming Dynasty, but due to its high toxicity, the scope of application was limited, and there were few records of its medicinal use.However many records of its medicinal use was found in the Compendium of Materia Medica(«»).By comparing the medical books that recorded Shao Jiu in previous dynasties, it is found that the Compendium of Materia Medica comprehensively records the relevant cognition and application of the medicinal use of Shao Jiu for the first time. The book lists in detail the causes of the toxicity of Shao Jiu and the methods to avoid it, comprehensively expounds its characteristics, efficacy and indications, lists a variety of ways to use it, skillfully uses Shao Jiu to treat syphilis sores, and proposes that high-concentration Shao Jiu can be used as a solvent for medical liquor.The record of Shao Jiu in the Compendium of Materia Medica had a profound impact on the medical liquor of later generations.The use of Shao Jiu in the Qing Dynasty continued to expand, and the types of medicinal liquor were also constantly enriched. The record of Shao Jiu in the Compendium of Materia Medica can also provide a reference for the medicinal use of modern liquor.

Abstract
OBJECTIVES There emerges increasing doubt regarding whether the policy composite indicators are applicable to the COVID-19 pandemic. A few early studies demonstrate that the association between some composite indicators of policy preparedness and the risk of COVID-19 is statistically insignificant, and the relation between any composite indicators and recovery process (e.g., vaccination coverage) remains unexplored. To examine the relation between composite indicators and pandemic risk (as well as the vaccination coverage) with robustness, this study applies different policy preparedness indicators by using data from multi-sources. STUDY DESIGN A cross-sectional analysis was performed. METHOD Regression analysis is adopted to examine the relation between four policy preparedness indicators (i.e., [1] International Health Regulations core capacity index, [2] Global Health Security Index, [3] epidemic preparedness index, and [4] World Governance Index) and COVID-19-confirmed cases/death/vaccination coverage at different time points. The linear regression is performed, and the spatial distribution of indicators are illustrated. RESULTS Countries with higher ranking in policy preparedness indexes can experience less severity of pandemic risk (e.g., confirmed cases and mortality) and faster recovery process (e.g., higher vaccination coverage). However, slight disparity in effectiveness exists across different indicators. CONCLUSION Results show that the policy preparedness indicators have predictive value of the confirmed cases, mortality, and vaccination coverage of COVID-19 pandemic, given sufficiently long-time span is observed.

Abstract
AIM To evaluate the utility of contrast-enhanced magnetic resonance angiography (CE-MRA) for identifying prostatic artery (PA) anatomy in patients with benign prostatic hyperplasia (BPH) before PA embolisation (PAE), using digital subtraction angiography (DSA) as the reference standard. MATERIALS AND METHODS A total of 176 patients underwent pelvic CE-MRA at 3 T. DSA was performed within the following 7 days. Two interventional radiologists compared the CE-MRA findings with DSA findings to assess the anatomy of the PAs. The rates of correct identification of the origins and collaterals of the PAs by CE-MRA were calculated. The utility for predicting the optimal X-ray tube angle obliquity for visualising the origins of the PAs by CE-MRA was evaluated. An exact McNemar's test was used to compare the detection rates of the PAs and the collaterals with DSA versus CE-MRA. A two-sided p-value of <0.05 was considered statistically significant. RESULTS Of the 376 PAs identified by DSA, CE-MRA correctly identified the origins of 369 vessels (98.1%), with a 1.9% false-negative rate and no false-positive results. Of the 57 total collaterals identified by DSA, CE-MRA identified 50 vessels correctly (87.7%), with a 12.3% false-negative rate and no false-positive results. No significant differences were observed between CE-MRA and DSA in the identification of the PA origins (p=0.824) and the collaterals (p=0.327). The optimal degree for an oblique projection to visualise the origins of the PAs could be predicted accurately (100%) by pre-procedural CE-MRA. CONCLUSION CE-MRA before PAE can reliably predict the PA anatomy and facilitate procedural planning.

Abstract
The aim of this work was to evaluate the relationships among respiratory syncytial virus infection, T cell immune response and intestinal flora. Peer-reviewed papers published in English were collected through extensive searches performed in PubMed, Web of Science, Google Scholar, and China National Knowledge Infrastructure databases. The articles were reviewed to extract relevant information on the immune responses of Th1/Th2 and Treg/Th17 to respiratory syncytial virus infection in the body. RSV (Respiratory syncytial virus, RSV) infection leads to imbalance between Th1/Th2 and Treg/Th17 immune cells, resulting in Th2 or Th17 dominant immune responses, which can generate immune disorder and aggravate clinical symptoms. Intestinal micro-organisms play very important roles in maintaining stable immune environment, stimulating immune system maturation and balancing Th1/Th2 and Treg/Th17 immune systems in children. In our review of various papers from around the world, we speculated that the steady state of intestinal bacteria was disturbed after children got infected with RSV, resulting in intestinal flora disorder. Then, the imbalance between Th1/Th2 and Treg/Th17 immune cells was increased. Both intestinal flora disorder and RSV infection could cause cellular immunity imbalance of Th1/Th2 or Treg/Th17, eventually leading to disease deterioration and even a vicious cycle. Normal intestinal flora can maintain immune system stability, regulate the dynamic balance of Th1/Th2 and Treg/Th17 and prevent or mitigate adverse consequences of RSV infection. Because probiotics can improve intestinal barrier function and regulate immune response, they can effectively be used to treat children with recurrent respiratory tract infections. Using conventional antiviral therapy strategy supplemented with probiotics in the treatment of clinical RSV infection may be better for the body.

Abstract
The North China Medical College typically represented medical colleges for traditional Chinese medicine in the 1930s when many of them were set up. It was based on the principles of centring on traditional Chinese medicine, following western medicine and integrated medicine in teaching. This led to the emergence of a great number of people with a high level of traditional Chinese medicine and strong belief in it. In terms of the textbooks and handouts for western medicine, compared to similar textbooks in other medical colleges, such as the Medical College of Xie He, at that time, the textbooks in the North China Medical College covered a variety of perspectives and categories. It was found that 20 textbooks for western medicine in the North China Medical College were designed reasonably in content and were simple and applicable in teaching. More importantly, it contained some traditional Chinese medicine in different degrees, with its typical characteristics. The course design and textbook compilation provided references for the teaching in contemporary medical universities.

Abstract
Glass fiber and liquid-modified polyvinyl alcohol polymer (SH Polymer) are used to reinforce granite residual soil. In this paper, scanning electron microscopy (SEM) tests and drop-weight tests were used to study the microscopic interaction mechanism and impact resistance of granite residual soil specimens reinforced by glass fiber and SH Polymer. Combined with the equivalent confining pressure theory, Mohr-Coulomb intensity lines were used to quantitatively analyze the reinforcement effect of glass fiber. The SEM results showed that the granite residual soil solidified by a 3.5 % SH polymer had a tighter bond between the flake clay particles. In addition, with the incorporation of glass fiber, these flake clay particles were cemented on the glass fiber along the long axis, forming a cementing system of flake clay particles and glass fiber. When the glass fiber content was 3.0 %, the impact resistance of the specimen reached its maximum, 32.16 kN. Using the equivalent confining pressure theory, the reinforcement effect of glass fiber on soil could be quantified by Δσ3.

Abstract
AIM To investigate the safety and efficacy of transarterial chemoembolisation (TACE) with bleomycin for hepatocellular carcinoma (HCC) unresponsive to doxorubicin. MATERIALS AND METHODS A randomised controlled trial was undertaken of HCC patients resistant to TACE with doxorubicin to assess the survival benefits of the experimental group (TACE with bleomycin) compared with the control group (TACE with doxorubicin). One hundred and seventy patients were allocated randomly between December 2015 and December 2017, and 80 patients of each group were analysed. The modified response evaluation criteria in solid tumours (mRECIST) was used to evaluated the tumour response every 4-6 weeks. The primary endpoint was median progression-free survival (mPFS) and median overall survival (mOS). Safety was assessed by post-procedure complications. RESULTS The study was completed in October 2018. Objective response rate (ORR) of the experimental group was 27.5% (22/80), mPFS and mOS was 5.8 and 8.1 months. ORR of the control group was 7.5% (6/80), mPFS and mOS was 2.9 and 4 months. The ORR were significantly different between two groups (χ2 = 0.348, p<0.05). The differences of mPFS and mOS between the two groups were statistically significant (χ2 = 2.865, p<0.05 and χ2 = 0.926, p<0.05, respectively). There were no significant difference in post-procedure complications (p>0.05) and no major complications occurred. CONCLUSION It is suggested that TACE with bleomycin is a safe and effective method for HCC and bleomycin can be a second-line chemotherapeutic agent for the HCC patients unresponsive to TACE with doxorubicin.

Abstract
Objective: To explore the application effect of sustainable skin-stretching device in scalp and soft tissue defect. Methods: From June 2017 to January 2020, 5 patients (3 males and 2 females, aged 31-57 (38.0±2.1) years) with large area of scalp and soft tissue defect and skull exposure were admitted to Department of Reparative and Reconstructive Surgery of the Second Hospital of Dalian Medical University. The wound area ranged from 16.0 cm×8.0 cm to 18.0 cm×12.0 cm. The sustainable skin-stretching device was installed after debridement operation for scalp wound. The wound was stretched from the 3rd day after installation of the device, at a basic speed of 1 mm/d and finished for 3 times on average. During stretching, close attention was paid to the changes in blood flow of the wound margin and the subjective feeling of the patients. When the result was negative in the squeezing and pinching test for wound margin after stretching, the further stretching was stopped, the final stretching state was maintained for 3 days, and the wounds were sutured directly. The wound healing during stretching of sustainable skin-stretching device and the occurrence of complications were observed. The rest wound areas after stretching for 5, 10, 15, and 20 days were measured. The wound healing and hair growth were observed during follow-up. Results: All the wounds of 5 patients was sutured directly after stretching for 19-23 d. There was no tension blister on the margin of wounds during stretching, and the margin of wounds healed well after being sutured without skin necrosis. After stretching treatment for 5-20 d, the wound areas were gradually decreased. During follow-up of 2-11 (4.5±1.5) months, the elasticity, color, feeling, and regenerated hair growth of the stretched scalp tissue were close to those of the surrounding normal skin tissue. The linear scar formed on the margin of wounds, but no scar formed on the wounds. Conclusions: The application of sustainable skin-stretching device can reduce the difficulty in repairing scalp and soft tissue defect, with the regenerated hair growing well after treatment, which is worthy of clinical promotion.

Abstract
Objective: To investigate the feasibility of coronary computed tomography angiography (CCTA) with the individualized contrast medium injection scheme based on body mass and iodine flow rate by using wide detector CT at 100 kV. Methods: From May 2018 to July 2018,270 patients with clinically suspected coronary artery disease underwent CCTA in TEDA International Cardiovascular Hospital. They were randomly divided into three groups, 90 cases in each group: group A was 0.5 ml/kg, group B was 0.6 ml/kg, the flow rate of contrast medium injection in group A and group B was (body mass×25 mg)/the concentration of contrast medium,group C was 0.8 ml/kg and the flow rate of contrast medium was 5 ml/s. Iohexol (iodine concentration 350 mgI/ml) was used in all three groups. The CT values of the aorta root in the three groups, the CT value of the middle segment of LAD and RCA, SNR、CNR、SD of the aortic root, subjective score of coronary artery and effective dose (ED) were compared. Results: There was no significant difference in CT value of aortic root, CT value of middle LAD and RCA, SNR、CNR、SD of the aortic root, subjective score of coronary artery among group A, group B and group C (all P>0.05). The flow rates of the three groups of contrast agents were statistically different (4.5±0.5 vs 4.5±0.5 vs 5, P=0.015), and there was no statistical difference between group A and group B (P>0.05) but lower than group C (P=0.015); the amount of contrast agent in the three groups was statistically different (32±3 vs 38±4 vs 53±7, P<0.001), group A<B Group<C group; there was no significant difference in ED between the three groups (1.5±0.5 vs 1.5±0.6 vs 1.3±0.6, P=0.613). Conclusions: CCTA imaging with a wide body detector based on a 0.5 ml/kg contrast agent dosage and a flow rate of ((body mass × 25)/350) ml/s individualized injection scheme can ensure the image quality while reducing the total amount of contrast agent and realizing individualized iodine flow rate.

Abstract
The viscoelastic behavior of supercooled glass-forming liquids along the binary join As4S3-GeS2 with As4S3 contents varying from 81.25 to 9 mol. % and correspondingly with structures varying from predominantly molecular to a three-dimensional tetrahedral network is studied by small-amplitude oscillatory shear parallel plate rheometry. The storage shear modulus G' shows a scaling behavior of G'(ω) ∼ ωn in the terminal (low-frequency) regime, where n varies between 1 and 2 and shows an increasingly anomalous departure from the expected value of 2 (Maxwell scaling) with increasing molecule content. A concomitant departure from the Maxwell scaling is also observed for the loss modulus G″ at frequencies above the G'-G″ crossover. On the other hand, the variation in the phase angle δ with the complex modulus indicates that the molecular liquid does not display a purely viscous response even at the lowest frequencies. These results, combined with an analysis of the relaxation spectra of these liquids, suggest that the anomalous behavior of molecular liquids may be linked to their rather broad relaxation spectrum and the presence of slow relaxation processes associated with molecular clusters. Additionally, these liquids are also characterized by a wide high-frequency plateau in the relaxation spectral density that can be linked to the rotational dynamics of the constituent molecules. Such fundamental differences between the rheological behavior of molecular and network liquids may explain the significantly higher fragility of the former.

Abstract
A new Doppler coherence imaging spectroscopy interferometer has been developed on the HL-2A tokamak for the scrape-off-layer impurity flow measurement. Its spatial resolution is estimated to be up to ∼0.8 mm in the horizontal direction and ∼9 mm in the vertical direction, with a field of view of ∼34°. Its typical temporal resolution is about 1 ms. This salient feature allows for time-resolved 2D measurements in short-time phenomena on HL-2A, such as edge localized modes. Group delay and interference fringe pattern were calibrated with a dedicated calibration system. The robustness of group delay calibration and the feasibility of the extrapolation model for fringe pattern calibration are demonstrated. In this paper, we report the details of the optical instruments, calibration, and the initial experimental results of this Doppler coherence imaging spectroscopy interferometer.

Abstract
OBJECTIVE Dysregulation of microRNAs (miRNAs) expression often resulted in abnormal cell behaviors. It has been demonstrated that miRs may serve as oncogenic or tumor suppressive functions in tumor. We investigated whether or not miR-144-3p has a role in the progression of human neuroblastoma (NB). PATIENTS AND METHODS 46 NB patients were enrolled in this study. miR-144-3p expression in NB tissues and cell lines was detected by reverse transcription-quantitative polymerase chain reaction. The biological functions of miR-144-3p in NB were detected by cell counting kit-8 assay, flow cytometry assay, and wound-healing assay. Luciferase activity assay and Western blot assay were performed to validate the direct targets of miR-144-3p. RESULTS We found miR-144-3p expression was reduced in NB tissues and cell lines and resulted in the stimulation of cell proliferation, cell cycle progression, and cell migration in vitro. Furthermore, we validated homeobox protein A7 (HOXA7) as a direct target of miR-144-3p. CONCLUSIONS Taken together, these results demonstrated the tumor suppressive role of miR-144-3p in NB and may advance the understanding of the underlying mechanisms of miR-144-3p and HOXA7 in NB.

Abstract
Macrophages play an important role in the immune system as a key host defense against pathogens. Non-polarized macrophages can differentiate into pro-inflammatory classical pathway-activated macrophages or anti-inflammatory alternative pathway-activated macrophages, both of which play central roles in breast cancer growth and progression in a process called polarization of macrophages. Classical pathway-activated and alternative pathway-activated macrophages can transform into each other and their transformational properties and orientation are determined by cytokines in the tumor microenvironment. Tumor-associated macrophages display many functions, such as tissue reforming, participating in inflammation and tumor growth in breast cancer progression. Some cytokines, such as interleukins and transcriptional activators, reside in the tumor microenvironment and influence tumor-associated macrophages. Chemotherapy is a common treatment for breast cancer and macrophages play an important role in mammary tumor cell migration, cancer invasion, and angiogenesis. This review summarizes the activities of tumor-associated macrophages in the mammary tumor, chemotherapeutic processes and some potential strategies for breast cancer therapy.

Abstract
Objective: To observe the safety and efficacy of lenvatinib for the treatment of medium-advanced hepatocellular carcinoma. Methods: A total of 36 patients with medium-advanced hepatocellular carcinoma from the First Medical Center of the Chinese PLA General Hospital were retrospectively analyzed from January 2018 to May 2019. All patients had shown tumor progression after at least 2 sessions of TACE. The patients were consisted of 30 males and 6 females with age range of 35 to 76 (54±10) years. Patients received orally administered lenvatinib at a dose of 12 mg once daily for patients ≥ 60 kg and 8 mg once daily for patients<60 kg. According to modified RECIST criteria the tumor response, disease control rate, overall survival and progression free survival were evaluated once every 6-8 weeks. The adverse events were recorded. Results: No patient was in complete response, 2 cases (5.7%) in partial response, and 5 cases (14.3%) in stable disease, respectively. Disease control rate was 20.0% (7/35), the overall survival was 11.5 months, and the progression free survival was 5.3 months. The overall incidence of adverse events was 66.7% (24/36). The most frequent adverse events were hypertension, proteinuria, hand-foot skin reaction and abdominal distension. Conclusion: Lenvatinib can extend the overall survival in a percentage of medium-advanced hepatocellular carcinoma patients who were unresectable and refractory to TACE. Although the incidence of adverse events is high, most of them are mild and reversible.

Abstract
AIMS To evaluate the therapeutic effect and safety of transarterial embolisation using a bleomycin-Lipiodol mixture and N-butyl-2-cyanoacrylate (NBCA)-Lipiodol mixture (BNL) for the treatment of polycystic liver disease (PLD). MATERIALS AND METHODS From June 2012 to July 2018, a total of consecutive 14 symptomatic patients (13 women and 1 man; mean age, 49.3±9.9 years) with PLD were referred and underwent transcatheter arterial embolisation (TAE) with BNL. RESULTS Technical success was achieved in all cases. PLD-related severe symptoms were improved remarkably in 13 of the treated patients. The mean maximum abdominal circumference decreased significantly from 100.6±9.4 to 94.9±9.1 cm (p<0.01). The total liver volume decreased significantly compared with pre-TAE in 13 patients at 6-12 months after TAE. It decreased from 9,776±2,219 to 8,303±2,009 cm3 (p<0.01). There were no major complications associated with the procedure. CONCLUSION TAE with the bleomycin-Lipiodol mixture and NBCA-Lipiodol mixture may be an effective method for treating symptomatic PLD patients, with improvement of symptoms and shrinkage of cyst volume.

Abstract
Objective: To compare the efficacy of prostatic artery embolization (PAE) in the treatment of patients with benign prostatic hyperplasia (BPH) with different prostatic volume (PV). Methods: In this single-center, retrospective study, 137 patients, mean age (70±11) years, range 50-89 years, undergoing PAE for BPH between January 2015 and May 2017 in Chinese PLA General Hospital were involved and divided into three groups according to the PV (group A, >80 ml; group B, 40-80 ml; group C, <40 ml). The changes of international prostate symptoms (IPSS) score, quality of life (QoL) score, and maximum urinary flow rate (Q(max)) were compared among the three groups at 1, 6, and 12 months post-PAE. Correlation between the proportion of prostate ischemia at 1 month post-PAE and the proportion of PV reduction at 12 month post-PAE were analyzed, also the correlation between both of them with IPSS and QoL score were analyzed, respectively. Results: Mean baseline prostate volumes were 110 ml in group A (n=62), 67 ml in group B (n=47) and 33 ml in group C (n=28). At 12 months post-PAE, the outcomes of IPSS score and Q(max) in group A were better than those in group B and C (all P<0.05).The proportion of prostate ischemia at 1 month post-PAE and proportion of PV reduction at 12 month post-PAE in group A, B, and C were 61.4%, 49.3%, 38.0%, and 47.3%, 29.3%, 24.6%, respectively. The proportion of prostate ischemia in group A was larger than that in group B and C (P=0.049, 0.004), also the proportion of PV reduction in group A was greater than that in group B and C (P<0.01). The proportion of prostate ischemia at 1 month post-PAE in all three groups were positively correlated with the proportion of PV reduction at 12 month post-PAE (r=0.699, P=0.024; r=0.719, P=0.019; r=0.821, P=0.004), and there were positive correlations between both of them and the improvement of IPSS score at 12 month post-PAE (0.5<r<1.0, all P<0.05), while no correlation with the improvement of QoL score. Conclusions: Patients with BPH with PV larger than 80 ml are more suitable for PAE. The proportion of prostate ischemia and prostate volume reduction after PAE can predict the efficacy of PAE.

Abstract
OBJECTIVE To investigate the effects of ganglioside [monostalotetra-hexosylganglioside (GM1)] on the expressions of caspase-3 and nerve growth factor (NGF) in rats with acute spinal cord injury (SCI). MATERIALS AND METHODS Male Sprague- Dawley (SD) rats were selected and randomly divided into Sham group, SCI group and GM1 administration group. The rats in Sham group, SCI group and GM1 group were subjected to behavioral examinations of Basso Beattie Bresnahan (BBB) and oblique-plate test at 1, 7 and 14 d after operation. The content of methylene dioxyamphetamine (MDA) and the activity of superoxide dismutase (SOD) of every rat in each group were measured by enzyme-linked immunosorbent assay (ELISA). Immunofluorescence staining assay was used to detect the expression levels of caspase-3 and NGF of rats in each group. The messenger ribonucleic acid (mRNA) and protein expressions of caspase-3 and NGF of rats in Sham group, SCI group and GM1 group were detected using reverse transcriptase-polymerase chain reaction (RT-PCR) and Western blotting assay. RESULTS The BBB scores and the results of oblique-plate test in Sham group, SCI group and GM1 group at 1, 7 and 14 d showed that the BBB scores and the results of oblique-plate test of rats in each group were significantly decreased at 1 d after SCI, and had different degrees of recovery at 7 and 14 d after injury. The results of ELISA detection revealed that SCI group had increased content of MDA and clearly decreased activity of SOD in comparison with Sham group; at the same time, MDA content in GM1 group was overtly lower than that in SCI group, while SOD activity was enhanced evidently in GM1 group compared with that in SCI group. According to immunofluorescence assay, significantly increased expression of caspase-3 and distinctly decreased expression of NGF were found in SCI group. However, this phenomenon was significantly reversed by GM1. RT-PCR and Western blotting assay severally proved that the mRNA and protein expressions of caspase-3 were raised in SCI group and decreased clearly after the administration of GM1; while the mRNA and protein expressions of NGF was significantly reduced in SCI group and overtly elevated after the administration of GM1. ANOVA showed that there were statistically significant differences in expressions of caspase-3 and NGF among Sham group, SCI group and GM1 group (p<0.05). CONCLUSIONS GM1 has an evident effect on the expressions of caspase-3 and NGF in rats with acute SCI, and is able to down-regulate the expression of caspase-3 and up-regulate the expression of NGF, so as to achieve its therapeutic effect on SCI.

Abstract
Abstract
Programmed death-ligand 1 (PD-L1) and its receptor programmed cell death protein 1 (PD-1) play important roles in modulating antitumor immune response and are targeted by checkpoint blockade immunotherapy. While PD-L1 expression in both tumor and host cells is associated with antitumor therapeutic efficacy, the exact contribution of PD-L1 in various tissue and cell compartments to antitumor immune response remains to be elucidated. Here we show that PD-L1 expression is markedly elevated in human and mouse mature adipocytes compared to their preadipocyte counterparts. When co-cultured with mouse splenocytes in vitro, adipocytes prevent anti-PD-L1 antibody from activating CD8+T cells. Genetic ablation of adipose PD-L1 obliterates the inhibitory effect of adipocytes on anti-PD-L1 antibody. Conversely, enforced PD-L1 expression in preadipocytes confers the antibody-inhibitory activity. GW9662, a pharmacologic inhibitor of peroxisome proliferator-activated receptor γ (PPARγ) in adipogenesis, selectively reduces PD-L1 expression in mouse adipose tissue. The same PPARγ antagonist also enhances the antitumor efficacy of checkpoint blockade antibodies for treating multiple mammary tumors. Our findings provide a previously unappreciated approach to bolster anticancer immunotherapy efficacy and suggest a mechanism for the role of adipose tissue in breast cancer progression.

Abstract
Transmembrane penetration of nanoparticles (NPs) promises an effective pathway for cargo delivery into cells, and offers the possibility of organelle-specific targeting for biomedical applications. However, a full understanding of the underlying NP-membrane interaction mechanism is still lacking. In this work, the membrane penetration behavior of NPs is statistically analyzed based on the simulations of over 2.2 ms, which are performed with dissipative particle dynamics (DPD). Influences from multiple factors including the NP concentration, shape and surface chemistry are taken into account. It is interesting to find that, the introduction of a partner NP would greatly facilitate the transmembrane penetration of a host spherical NP. This is probably due to the membrane-mediated cooperation between the NPs. Moreover, the proper selection of a partner NP with specific surface chemistry is of great significance. For example, the best partner for a hydrophilic NP to achieve transmembrane penetration is a Janus-like one, in comparison with the hydrophilic, hydrophobic or randomly surface-decorated NPs. Furthermore, such a partner-facilitating effect in NP translocation also works for a shaped NP although less pronounced. Our results are helpful for a better understanding of the complicated nano-bio interactions, and offer a practical guide to the NP-based drug delivery strategy with high efficiency.

Abstract
We remodeled and tested our semisoft 20cc ventricle and made a new bileaflet flap inflow valve. Housings, bases, outflow valve, and a newly designed diaphragm were all made by vacuum forming and put together by radiofrequency welding or glue. In vitro, the ventricle produced a cardiac output of 2.5 to 3.0 L/min and showed reliable durability results. Hematological testing showed no important thrombogenecity of the new valve. Cardiac output was higher than expected for the volume of the ventricle, perhaps because of stretching or flow through. Animal experiments with the left ventricular assist device (LVAD) version was done at Ohio State University. Earlier in Utah, we did 20 cc total artificial heart (TAH) implantations and LVAD experiments in lambs and recently in calves with the 60cc TAH version. A soft ventricle is easy to implant and low in production costs.

Abstract
Objective: To investigate the effects of denatured collagen type Ⅰ on differentiation of human fibroblasts into myofibroblasts. Methods: A small amount of normal skin donated by burn patients undergoing scar surgery was collected. Human fibroblasts were obtained by method of explant culture and then sub-cultured. The fourth passage of cells were used in the following experiments. (1) Fibroblasts were divided into normal collagen group and denatured collagen group according to the random number table, with 10 wells in each group. Fibroblasts in normal collagen group were cultured on normal collagen type Ⅰ coated coverslips. Fibroblasts in denatured collagen group were cultured on denatured type Ⅰ collagen coated coverslips. Expression of proliferating cell nuclear antigen (PCNA) was detected by immunohistochemical method, and the percentage of PCNA positive cells was calculated. (2) Another batch of fibroblasts were grouped and treated as in (1), with 12 wells in each group. Proliferation activity of cells was determined with methyl-thiazolyl-tetrazolium colorimetry method. (3) Another batch of fibroblasts were grouped and treated as in (1), and the microfilament morphology of cells was observed by rhodamine-phalloidin staining. (4) Another batch of fibroblasts were grouped and treated as in (1). Expression of α smooth muscle actin (α-SMA) of cells was detected by immunohistochemical method, and expression of OB-cadherin of cells was detected by immunofluorescence method. (5) Another batch of fibroblasts were divided into normal collagen, denatured collagen, and common coverslips groups according to the random number table, with 6 wells in each group. Fibroblasts in normal collagen and denatured collagen groups were treated as in (1), while fibroblasts in common coverslips group were cultured on coverslips without collagen coating. Expressions of α-SMA and OB-cadherin of cells were determined with Western blotting. (6) Another batch of fibroblasts were grouped and treated as in (5), and then the mRNA expressions of collagen type Ⅰ, collagen type Ⅲ, and α-SMA of cells were determined with real-time fluorescent quantitative reverse transcription polymerase chain reaction. Data were processed with t test, one way analysis of variance, and least-significant difference test. Results: (1) The percentage of PCNA positive cells in denatured collagen group was (83±9)%, significantly higher than (29±9)% in normal collagen group (t=13.53, P<0.01). (2) The proliferation activity of fibroblasts in denatured collagen group was 0.32±0.06, significantly higher than 0.25±0.05 in normal collagen group (t=3.06, P<0.01). (3) The microfilament of fibroblasts in normal collagen group was arranged vertically and in parallel way, paralleling the long axis of cells. The microfilament of fibroblasts in denatured collagen group was denser and thicker. (4) Most fibroblasts in normal collagen group showed long shuttle-like shape typically. Morphology of fibroblasts in denatured collagen group changed, and cells were obviously spreading. Expressions of α-SMA and OB-cadherin of fibroblasts in denatured collagen group were stronger than those in normal collagen group. (5) Expressions of α-SMA of fibroblasts in denatured collagen, normal collagen, and common coverslips groups were respectively 1.69±0.41, 0.89±0.27, and 1.46±0.42. Expression of α-SMA of fibroblasts in denatured collagen group was significantly higher than that in normal collagen group (P<0.01). Expressions of OB-cadherin of fibroblasts in denatured collagen, normal collagen, and common coverslips groups were respectively 5.17±0.28, 2.21±0.10, and 4.01±0.56. Expression of OB-cadherin of fibroblasts in denatured group was significantly higher than that in normal collagen group (P<0.01). (6) There was no significant difference in mRNA expression of collagen type Ⅰ of fibroblasts in denatured collagen, normal collagen, and common coverslips groups (F=2.71, P>0.05). The mRNA expressions of collagen type Ⅲ and α-SMA of fibroblasts in normal collagen group were significantly lower than those in denatured collagen group (P<0.01). Conclusions: Denatured collagen type Ⅰ may influence the activity of fibroblasts, thus inducing fibroblasts differentiating into myofibroblasts.

Abstract
The development of medicine experienced a long history, and the origin of medicine is not appeared overnight. Due to the lack of historical data, the question of the origin of medicine has not been agreed upon. As an ancient primitive religion, Shamanism retains the use of hallucinogenic drugs in its early religious activities rather well, providing a guidance for exploring the cognition on drugs in early human. Through the review of the hallucinogenic plants used by shaman religious activities in different countries and areas, it was found that hallucinogenic drugs can be classified into two categories: single and mixed, which came mainly from plants and fungi, and the origin of hallucinogenic drugs has a high fitting degree with Shaman location. The study result suggests that, based on the worldwide research literature on the application of such hallucinogens with local characteristics in the shamanistic religious activities, it is very likely that important clues can be found to understand the facts of discovery and application of natural drugs, thus providing a new approach for the studies on the origin of drugs.

Abstract
Objective: To observe the effects of transient exposure to high glucose on biological behaviors of human dermal microvascular endothelial cells cultured in vitro. Methods: The dividing method and treatment of cells for the detection of all indexes in this study were as follows. Human dermal microvascular endothelial cells of the 4th passage were divided into 3 groups according to the random number table, with 12 wells in each group. Cells in control group (C) were cultured with complete culture solution containing 5 mmol/L D-glucose for 7 d. Cells in transient high glucose group (THG) were cultured with complete culture solution containing 30 mmol/L D-glucose for 2 d and complete culture solution containing 5 mmol/L D-glucose for 5 d. Cells in prolonged high glucose group (PHG) were cultured with complete culture solution containing 30 mmol/L D-glucose for 7 d. (1) The cell morphology in groups C and PHG on culture day 7 and that in group THG on culture day 2 and 7 was observed by inverted optical microscope. (2) On culture day 0, 2, 4, and 7, cell proliferation rate was determined by cell viability analyzing counter. (3) After culture day 2, the scratch experiment was performed, and the cells were further cultured. At post scratch hour (PSH) 0, 24, 48, 72, 96, and 120, the scratch area was measured, and the cell migration rates of the latter 5 time points were calculated. (4) On culture day 0, 2, 4, and 7, the cell apoptosis rate was determined by cell analyzer. (5) Cells were seeded into Matrigel to culture for 24 h after culture day 7. The formation of vessel-like structure was observed by inverted optical microscope. The length and number of branch point of vessel-like structure were calculated. (6) On culture day 2, 4, and 7, mRNA expression of vascularization-related gene tissue inhibitor of matrix metalloproteinase-3 (TIMP-3) was determined with real-time fluorescent quantitative reverse transcription polymerase chain reaction. Data were processed with analysis of variance of factorial design, analysis of variance for repeated measurement, one-way analysis of variance, and LSD test. Results: (1) Cells in group C exhibited ovary shape in cobble stone order on culture day 7. Cells in group THG exhibited long ovary shape and lost cobble stone order on culture day 2 and kept the same changes on culture day 7. Cells in group PHG exhibited long ovary shape and lost cobble stone order on culture day 7. (2) On culture day 0, there was no significant difference in cell proliferation rate among the 3 groups (F=0.23, P>0.05). On culture day 2, cell proliferation rates in groups THG and PHG were similar (P>0.05), which were significantly lower than the cell proliferation rate in group C (with P values below 0.01). On culture day 4 and 7, the cell proliferation rates in groups THG and C were similar (with P values above 0.05), which were significantly higher than those in group PHG (with P values below 0.01). (3) At PSH 24-120, the cell migration rates in groups THG and PHG were similar (with P values above 0.05), which were significantly lower than those in group C (with P values below 0.01). (4) On culture day 0, there was no statistically significant difference in cell apoptosis rate among the 3 groups (F=0.78, P>0.05). On culture day 2, cell apoptosis rates in groups THG and PHG were similar (P>0.05), which were significantly higher than the cell apoptosis rate in group C (with P values below 0.01). On culture day 4 and 7, the cell apoptosis rates in groups THG and C were similar (with P values above 0.05), which were significantly lower than those in group PHG (with P values below 0.01). (5) The length of vessel-like structure of cells in group THG was (1.84±0.10)×10(5) μm, close to (1.82±0.11)×10(5) μm in group PHG (P>0.05), both significantly shorter than (2.75±0.23)×10(5) μm in group C (with P values below 0.01). The numbers of branch point of vessel-like structure of cells in groups THG and PHG were 43±5 and 46±8 respectively, which were close to each other (P>0.05) and both significantly less than 103±21 in group C (with P values below 0.01). (6) On culture day 2, 4, and 7, mRNA expressions of TIMP-3 of cells in groups THG and PHG were similar (with P values above 0.05), which were significantly lower than those in group C (with P values below 0.05). Conclusions: Transient exposure to high glucose can cause metabolic memory of morphology, migration, and angiogenesis in human dermal microvascular endothelial cells cultured in vitro, resulting in sustained changes in biological behaviors. The mechanism may be related to the changes of vascularization-related genes.

Abstract
Objective: To investigate the influence of depression levels on regulatory T cells (Tregs) in patients with non-M3 acute myeloid leukemia (AML). Methods: A total of 63 patients with primarily diagnostic non-M3 AML and 25 healthy controls were enrolled, and the levels of depression by using HADM score and the percentages of Tregs by flow cytometry were evaluated in pre-treatment and post-treatment, respectively. Results: After every course of chemotherapy, the percentages of Tregs of PBMNC in AML showed the higher level of (6.48±1.81)% than those of (4.99±1.29)% in control (P= 0.001). There was no difference among different levels of depression groups after the first cycle. However, the percentages of Tregs increased with the worse of depression after the second and third cycles. Partial correlation analysis after adjusting age indicated that the percentages of Tregs showed no correlation with the levels of depression after the first cycle (correlation coefficient, 0.120, P=0.345), and showed the positive correlation with depression levels after the second and third cycles (correlation coefficient, 0.619 and 0.614, all P values <0.05). Conclusion: The depression levels showed an association with the percentages of Tregs in patients with non-M3 AML, which could be observed only after the second cycles of chemotherapy.

Abstract
A straightforward method for synthesizing the pyrazole N-oxides from N-propargylamines and AgNO2 through oxidation/cyclization reaction had been developed. AgNO2 was used as the NO source for the first time to synthesize pyrazole N-oxides. Various substituted groups on N-propargylamines proceeded smoothly, and the desired products were obtained in good yields.

Abstract
Here, we applied a two-stage clonal expansion model of morphological (cell-size) evolution to a long-term evolution experiment with Escherichia coli. Using this model, we derived the incidence function of the appearance of cell-size stability, the waiting time until this morphological stability, and the conditional and unconditional probabilities of morphological stability. After assessing the parameter values, we verified that the calculated waiting time was consistent with the experimental results, demonstrating the effectiveness of the two-stage model. According to the relative contributions of parameters to the incidence function and the waiting time, cell-size evolution is largely determined by the promotion rate, i.e., the clonal expansion rate of selectively advantageous organisms. This rate plays a prominent role in the evolution of cell size in experimental populations, whereas all other evolutionary forces were found to be less influential.

Abstract
OBJECTIVE Epithelial-mesenchymal transition (EMT) plays an important role in the malignant transformation of cancer. MicroRNAs are a group of small non-coding RNA molecules that down-regulate the expression of genes involved in tumorigenesis. Although microRNA-185 (miR-185) participates in the pathogenesis of several types of cancer, its relationship with EMT in human hepatocellular carcinoma (HCC) has not been investigated. The present study aims to elucidate the regulatory effects of miR-185 on EMT in HCC cells. MATERIALS AND METHODS MTT and an in vitro wound-healing assay were performed to determine cell growth and metastasis potential, respectively. Real-time PCR was used to measure the mRNA expression of miR-185 and Six2. In addition, protein expression levels of Six2 and EMT-related markers were determined by western blot. RESULTS Our study showed that miR-185 was significantly down-regulated in HCC cells. Also, a luciferase reporter gene assay confirmed Six2 as a direct target of miR-185. Functional analyses indicated that miR-185 up-regulation remarkably suppressed cell growth and the metastatic potential of HCC cells. We also found that ectopic expression of miR-185 reversed EMT via the up-regulation of E-cadherin and down-regulation of vimentin in epithelial and mesenchymal HCC cells. CONCLUSIONS miR-185 suppresses cell growth and EMT progression by targeting Six2, providing a novel target for the molecular treatment of liver malignancies.

Abstract
Manipulating molecular assembly is significant for achieving materials with desirable performances. In this paper, two nonionic surfactants, Span 20 and Triton X-100, are used to tune the nucleation and fiber growth of a molecular gelator 2,3-di-n-decyloxyanthracene (DDOA). Confocal microscopic images show that Span 20 induces elongation of DDOA spherulites, and promotes fiber side branching. In contrast, Triton X-100 enhances the primary nucleation of DDOA leading to the formation of smaller DDOA spherulites, and promotes fiber tip branching. (1)H NMR investigation demonstrates strong interactions between the hydrophobic tails of the surfactants and the alkyl chains of DDOA molecules.The interactions significantly reduce the diffusion of DDOA molecules. The different effects of the two surfactants could be attributable to their different alkyl hydrophobic tails. The hydrophobic tail of Span 20 is similar to the alkyl chain of DDOA, which could promote the adsorption of Span 20 on the fiber side surface rich in alkyl chains of DDOA.While the benzene ring in the hydrophobic tail of Triton X-100 could facilitate the primary nucleation of DDOA and the adsorpion of Triton X-100 on the fiber tip surface rich in aromatic structure of DDOA. The observations of this work will help the development of a convenient approach to tune the fiber network structure of molecular gels.

Abstract
Cell reprogramming mediated by histone methylation and demethylation is crucial for the activation of the embryonic genome in early embryonic development. In this study, we employed quantitative real-time polymerase chain reaction (qRT-PCR) to detect mRNA levels and expression patterns of all known histone demethylases in early germinal vesicle stage and in vitro-matured metaphase II (MII) oocytes (which are commonly used as donor cells for nuclear transfer). On screening, the Jumonji domain containing 1C (JMJD1C) gene had the highest level of expression and hence was used for subsequent experiments. We also found that JMJD1C was primarily expressed in the nucleus and showed relatively high levels of expression at the 2-cell, 4-cell, 8-cell, 16-cell, morula, and blastocyst stages of embryos developed from MII oocytes fertilized in vitro. Further, we knocked down the JMJD1C gene in MII oocytes using siRNA and monitored the cleavage of zygotes and development of early embryos after in vitro fertilization. The results showed that the zygote cleavage and blastocyst rates of the transfection group were reduced by 57.1 ± 0.07 and 50 ± 0.01% respectively, which were significantly lower than those of the negative control group (P < 0.05). These data suggest that JMJD1C plays a key role in the normal development of early bovine embryos. Our results also provide a theoretical basis for the investigation of the role and molecular mechanism of histone demethylation in the early development of bovine embryos.

Abstract
In this study, the performance of 300 Changbaishan Black cattle treated for superovulation from June to September was evaluated to determine the optimal conditions and herds for bovine embryo production. Data analysis revealed that cattle treated in July and August had higher numbers of available embryos (NAE), M1 embryos (NM1), and total embryos (NTE), as well as a higher percentage of M1 embryos (PM1). The temperature and precipitation observed during July and August were greater than those seen in the other two months; strong correlations were observed between these traits and the choice of month of treatment. In addition, multiparous cattle showed a better performance, higher NTE, NAE, NM1, and PM1 values, higher percentages of available embryos, and a lower percentage of degenerated embryos. The co-efficient correlation analysis showed that the month chosen for the treatment did not affect the superovulation traits of nulliparous cattle; however, the choice of the month affected multiparous cattle. Multiparous and nulliparous cattle exhibited many significant differences when treated in July and in August. In addition, the superovulatory traits of multiparous cattle, and not the nulliparous cattle, were strongly correlated to the choice of month of treatment. The results suggested that superovulation is more effective during a period with appropriate environmental temperature and humidity, and that multiparous cattle are more suitable for morula production.

Abstract
In this study, expression levels of miRNAs (miRNAs), miR-375 and miR-7, were detected in different tissues of cattle to determine whether adenohypophysis-prefer or exclusively expressed miRNAs, and target genes could be predicted by TargetScan, RNA22, and other software. Target genes related to pituitary function or reproductive traits were identified using a dual-luciferase assay. miR-375 and miR-7 were expressed differently in various tissues. miR-375 and miR-7 showed higher expression in the adenohypophysis, and there was a significant difference compared with expression in other tissues (P < 0.01). The binding sites for miR-7 were the mRNAs of bone morphogenetic protein receptor type II (BMPR2), prostaglandin F2 receptor negative regulator, gonadotropin-releasing hormone receptor, follicle-stimulating hormoneβ, somatostatin receptor 1, and interleukin-1β by bioinformatic analysis; similarly, the mRNAs of BMPR2 and leptin contained binding sites for miR-375, suggesting that these genes are affected by miR-7 or miR-375. Dual-luciferase reporter assays showed that miR-7 regulated prostaglandin F2 receptor negative regulator expression, while miR-375 regulated BMPR2 expression. The mutated plasmid and miRNA mimics were used to co-transfect NIH3T3 cells; luciferase reporter assays showed that the inhibition of luciferase activity in the wild-type cells dramatically decreased from 75 to 26% with a 3-5-nucleotide mismatch mutation into the seed region of miR-7. miR-375 had nearly lost the ability to inhibit luciferase activity, suggesting that GTCTTCC is the site of interaction between miR-7 and the prostaglandin F2 receptor negative regulator sequence and that GAACAAA is the site of interaction between miR-375 and the BMPR2 sequence.

Abstract
Early rehabilitative therapy is important for patients with hypertensive cerebral hemorrhage to improve long-term function of the extremities. Vascular endothelial growth factor (VEGF) is closely associated with the pathogenesis of hypertension. To identify the markers contributing to the genetic susceptibility to hypertensive cerebellar hemorrhage (HCH) and rehabilitative treatment, we examined the potential association between HCH and 12 single nucleotide polymorphisms of the VEGF gene. Participants included 244 patients with HCH and 251 healthy controls from our rehabilitation department. The T allelic frequencies of the rs3025020 (intron 6) and rs3025039 (3'-UTR) polymorphisms were significantly higher in the patients with HCH than in the healthy controls (rs3025020 T allele: P = 0.0002, OR = 1.619, 95%CI = 1.256-2.088; rs3025039 T allele: P = 0.001, OR = 1.682, 95%CI = 1.246-2.270). Strong linkage disequilibrium was observed in three blocks (D' > 0.9), and significantly more C-G-C (rs3025020, rs3025030, and rs3025039) haplotypes (P = 0.001) were found in the controls in block 3. Significantly more T-G-C haplotypes were found in the patients with HCH (P = 0.046). Further genotype and clinical phenotype correlation study of the rs3025039 carriers showed that Fugl-Meyer and Barthel index scores were lower in the patients with the TT genotype relative to CT + CC genotypes (P < 0.01). These findings point to a role for VEGF polymorphism in HCH, and may be informative for future investigations on the pathogenesis of rehabilitative treatment.

Abstract
BACKGROUND Gray matter (GM) atrophy and disrupted intrinsic functional connectivity (IFC) are often present in patients with amnestic mild cognitive impairment (aMCI), which shows high risk of developing into Alzheimer's disease. Little is known, however, about the relationship between GM atrophy and altered IFC, and whether they are related to cognitive decline. METHOD A total of 30 aMCI and 26 cognitively normal (CN) subjects were recruited for this study. Optimized voxel-based morphometric and resting-state functional connectivity magnetic resonance imaging approaches were performed to measure the GM volumes (GMVs) and atrophy-related IFC, respectively. Multivariate linear regression analysis was used to examine the effects of GM atrophy and IFC on cognitive performance across subjects, after controlling for the effects of age, education, gender and group. RESULTS Compared with CN subjects, aMCI subjects showed significantly reduced GMVs and decreased IFC in the frontal-parietal and medial temporal lobe systems. Multivariate regression analysis further demonstrated that the GMVs and decreased IFC simultaneously affected the cognitive function. Specifically, GMVs were positively correlated with cognitive performances, including global cognition and episodic memory, and showed a strong trend in correlation between GMVs and non-episodic memory, whilst IFC was positively correlated with the above three cognitive measures, across all subjects. In addition, significant correlation was found between GMVs and altered IFC strength across all subjects. CONCLUSIONS Our findings demonstrated that GMVs and IFC jointly contribute to cognitive performance, and combining quantitative information about GMVs and the strength of functional connectivity may serve as an indicator of cognitive deficits in non-demented elderly.

Abstract
Calpain-3 (CAPN3) is a member of the calpain family of Ca(2+)-regulated cysteine proteases, which play an important role in sarcomere remodeling and mitochondrial protein turnover, and thus, regulating beef tenderness in cattle. Currently, multiple CAPN3 transcripts have been detected in human, monkey, rat, and rabbit. However, whether this transcript is present in cattle remains unknown. In this study, we identified 2 CAPN3 transcripts in the skeletal muscle individuals of local black cattle from Jilin, China. One transcript corresponded to the known full-length protein and was referred to as CAPN3a, while the second transcript did not contain exons 2-19 and contained a single-nucleotide insert in the penultimate base of exon 1 compared to CAPN3a; this protein was referred to as CAPN3b. The expression level of CAPN3b was approximately 50-fold lower than that of CAPN3a. Moreover, CAPN3b mRNA was not translated into a functional protein because it had lost essential domains according to bioinformatic analysis. Our results not provide a foundation for understanding the function of CAPN3, but also are useful for further elucidating the effect of CAPN3 on meat quality in cattle.
