Abstract
Objective: To establish the key question list for the development of evidence- based guideline in China according to the content and limitation of current evidence-based guidelines around the world. Methods: First, we introduced the evidence-based guidelines in detail which met the criteria based on World Health Organization guideline development handbook and then formulated the draft list of key questions for the development of evidence-based guidelines. At last, the Delphi method was used to determine the list of key questions in developing evidence-based guidelines of colorectal cancer screening. Results: Totally, 34 questionnaires were collected, with experts from clinical and epidemiological fields. The average experts' authority coefficient was 0.81, indicating a high degree of authority. The concentration of opinions on all items in the questionnaire was relatively high, with the full score ratio greater than 75% and the coefficient of variation less than 0.3. The list of key questions on evidence-based guidelines for colorectal cancer screening has been divided into six parts: epidemiological problems, risk classification, screening age, screening tools, implementation and selection of steering group members, which covers the issues that need to be considered in the development of evidence-based colorectal cancer screening guidelines in China. Conclusion: The key question list for evidence-based guideline development in our study can be applied to the development of evidence-based guidelines for colorectal cancer screening in the future, as well as the development of evidence-based guidelines for other cancer screening in China.

Abstract
This study aimed to create prognostic signatures to predict AML patients' survival using alternative splicing (AS) events. The AS data, RNA sequencing data, and the survival statistics of 136 AML patients were obtained from The Cancer Genome Atlas (TCGA) and TCGA SpliceSeq databases. Total 34,984 AS events generated from 8,656 genes, 2,583 of which were survival-associated AS events, were identified using univariate Cox regression. The prognostic models constructed using independent survival-associated AS events revealed that low-risk splicing better predicted patients' survival. ROC analysis indicated that the predictive efficacy of the alternate terminator model was best in the area under the curve at 0.781. Enrichment analysis revealed several important genes (TP53, BCL2, AURKB, PPP2R1B, FOS, and BIRC5) and pathways, such as the protein processing pathway in the endoplasmic reticulum, RNA transport pathway, and HTLV-I infection pathway. The splicing network of splicing events and factors revealed interesting interactions, such as the positive correlation between HNRNPH3 and CALHM2-13010-AT, which may indicate the potential splicing regulatory mechanism. Taken together, survival-associated splicing events and the prognostic signatures for predicting survival can help provide an overview of splicing in AML patients and facilitate clinical practice. The splicing regulatory network may improve the understanding of spliceosomes in AML.

Abstract
Objective: To investigate the clinical features and improve the diagnosis and treatment of anomalous origin of the left coronary artery from the right coronary sinus with an interarterial course (ALCA-R-IAC) between the ascending aorta and main pulmonary artery in children. Methods: A retrospective analysis of the clinical manifestation, laboratory test, radiological feature, treatment and prognosis were conducted in four female children presented with ALCA-R-IAC in Beijing Children's Hospital from November 2015 to June 2018. Results: The four girls with onset age of 7.5-14.7 years were diagnosed with ALCA-R-IAC by CT coronary angiography (CTCA). Four children presented with exercise-induced syncope and clinical manifestations of acute myocardial infarction including 3 patients with acute left heart failure, 1 cardiogenic shock and 1 cardiac arrest. Nervous system involvement was found in one patient. Troponin I increased significantly to 20.65-50.00 μg/L in the four patients. Electrocardiogram (ECG) developed signs of left main coronary artery involvement. Echocardiography revealed reduced left ventricular ejection fraction (LVEF) of 25%-45% in three children and suspected anomalous origin of the left coronary artery in one child. CTCA showed an anomalous left coronary artery originating from the right coronary sinus, which had an interarterial course between the aorta and pulmonary artery leading to a slim left main coronary trunk. Two children underwent unroofing procedure and the other two children in whom physical activities were restricted received conservative managements. During a regular follow-up period of 12-43 months, all the children survived without recurrent symptoms and had good prognosis. Conclusions: ALCA-R-IAC can present as exercise-related syncope and acute myocardial infarction, even sudden death in children and adolescents. CTCA is helpful to clarify the early diagnosis of ALCA-R-IAC. Surgical intervention is the main treatment for ALCA-R-IAC and strenuous physical activities should be avoided.

Abstract
Objective:To investigate the clinical features, diagnosis, treatment and prognosis of myoepithelial carcinoma of the head and neck. Method:The clinical data of 59 patients with head and neck myoepithelial carcinoma admitted from January 2012 to October 2018 were analyzed retrospectively. The data was analyzed with SPSS 21.0 statistical software. Result:The follow-up period was 6 to 131 months. The mean follow-up time was 36 months. One patient(1.7%) was lost to follow-up, 17 patients(28.8%) had postoperative local recurrence, 8 patients(13.6%) had distant metastasis, and 5 patients(8.5%) had cervical lymph node metastasis; 14 patients(23.7%) died. The 1-, 3-, and 5-year cumulative survival rates were 92%, 73%, and 62%, respectively. Survival rate curves of different treatment methods were significantly different by Gehan method(P<0.05). Compared between the two groups, there was significant difference between surgery alone and surgery plus radiotherapy than radiotherapy alone and chemotherapy alone(P<0.05). There was no significant difference between the other two treatment methods. Multivariate logistic regression analysis showed that tumor location, clinical stage and survival status and local recurrence rate were significantly correlated(P<0.05), but gender, age and survival status and local recurrence rate were not significantly correlated(P>0.05). Conclusion:The incidence of myoepithelial carcinoma is low, and the clinical manifestations and imaging studies lack specificity. The tumor is prone to local recurrence, invasive, and has a high incidence of distant metastasis. It is a highly malignant tumor. Surgical treatment is preferred and the requirements for first surgery are high, and major salivary glands and advanced tumors(stage Ⅲ-Ⅳ) are risk factors for survival and local recurrence. Early diagnosis and early treatment can significantly improve the survival rate of patients, reduce the local recurrence rate of tumors, and improve the prognosis of patients.

Abstract
Objective:To summarize the treatment and effect of children with parotid hemangioma. Method:Thirty-three children with parotid hemangioma were treated with drug in 22 cases, 9 of which received propranolol orally, accounting for 27%; 13 cases underwent B-ultrasound guided bleomycin injection, accounting for 40%; another 11 cases were used. The treatment of surgical removal of hemangioma, accounting for 33%. Result:In 22 children with drug therapy, the evaluation criteria were evaluated by Achauer et al. 12 cases of grade Ⅳ, accounting for 54.5%; 7 cases of grade Ⅲ, accounting for 31.8%; 2 cases of grade Ⅱ, accounting for 9%. For example, accounted for 4.5%; 2 of them(1 in gradeⅠand Ⅱ) were treated with drug therapy for 6 months after surgical resection of hemangioma. Eleven children underwent surgical resection of hemangioma, and 8 patients underwent complete resection of the tumor, accounting for 73%. Among them, 3 patients had residual hemangiomas during operation, and the residual tumor was treated with bleomycin. This group of medications showed that children aged<12 months, after oral propranolol, the tumors were reduced to varying degrees, the most significant change within 1 week after administration, and then the tumor was further reduced until the end of treatment. Conclusion:B-ultrasoun lower bleomycin injection in children with parotid hemangioma is effective, and the incidence of adverse reactions is low, but multiple courses of treatment are required. For patients with poor drug treatment, recurrence or limited range, surgical resection of blood vessels can be selected. Tumor surgery should pay attention to the choice of indications and surgical operation skills, reduce the risk of facial nerve injury and postoperative facial scars. There are many different treatments for infantile hemangioma, but there is still no treatment for all children. The drug treatment of this group showed that after oral propranolol, the tumors were all reduced to varying degrees, the color became lighter, the texture became softer, and the change was most significant within 1 week after administration, and then the tumor was further reduced until the end of treatment. B-ultrasound guided bleomycin injection in children with parotid hemangioma is effective. After 1-2 courses of treatment, the tumor shrinks significantly and the incidence of adverse reactions is low. Drug treatment of parotid hemangioma in children is simple. A safe and effective method. For children with poor drug treatment, recurrence or limited range, surgical treatment of hemangioma can be selected. Surgery should pay attention to the choice of indications and surgical operation skills, reduce the risk of facial nerve injury and postoperative facial scars.

Abstract
The plant flavonoid dogma proposes that labile plant flavonoid carbocations (PFCs) play vital roles in the biosynthesis of proanthocyanidins (PAs). However, whether PFCs exist in plants and how PFCs function remain unclear. Here, we report the use of an integrative strategy including enzymatic assays, mutant analysis, metabolic engineering, isotope labeling and metabolic profiling to capture PFCs and demonstrate their functions. In anthocyanidin reductase (ANR) assays, an (-)-epicatechin conjugate was captured in protic polar nucleophilic methanol alone or methanol-HCl extracts. Tandem mass spectrum (MS/MS) analysis characterized this compound as an (-)-epicatechin-4-O-methyl (EOM) ether, which resulted from (-)-epicatechin carbocation and the methyl group of methanol. Acid-based catalysis of procyanidin B2 and B3 produced four compounds, which were annotated as two EOM and two (+)-catechin-4-O-methyl (COM) ethers. Metabolic profiling of seven PA pathway mutants showed an absence or reduction of two EOM ether isomers in seeds. Camellia sinensis ANRa (CsANRa), leucoanthocyanidin reductase c (CsLARc), and CsMYB5b (a transcription factor) were independently overexpressed for successful PA engineering in tobacco. The EOM ether was remarkably increased in CsANRa and CsMYB5b transgenic flowers. Further metabolic profiling for eight green tea tissues revealed two EOM and two COM ethers associated with PA biosynthesis. Moreover, an incubation of (-)-epicatechin or (+)-catechin with epicatechin carbocation in CsANRa transgenic flower extracts formed dimeric procyanidin B1 or B2, demonstrating the role of flavan-3-ol carbocation in the formation of PAs. Taken together, these findings indicated that flavan-3-ol carbocations exist in extracts and are involved in the biosynthesis of PAs of plants.

Abstract
Objective: To investigate chromosome abnormality rate and related factors of spontaneous abortion in early pregnancy. Methods: A total of 831 tissue samples of spontaneous abortion in early pregnancy were collected from June 2015 to August 2018 in the First Affiliated Hospital of Nanjing Medical University. Chromosomal copy number was analyzed by next generation sequencing (NGS). The relationships between chromosome abnormality and maternal age, in vitro fertilization-embryo transfer (IVF-ET) pregnancy, number of previous spontaneous abortions, history of live birth were analyzed by statistical methods. Results: Among 831 tissue samples of spontaneous abortion in early pregnancy, 461 (55.5%, 461/831) were found to have chromosome abnormalities. Maternal age (OR=1.107, 95%CI: 1.070- 1.145) and history of live birth (OR=1.909, 95%CI: 1.182-3.083) were the positive correlative factors of chromosome abnormality. Times of previous spontaneous abortion (OR=0.807, 95%CI: 0.702-0.928) and IVF-ET pregnancy (OR=0.554, 95%CI: 0.404-0.760) were the negative correlative factors of chromosome abnormality. Conclusions: Chromosome abnormality is an important cause of spontaneous abortion in early pregnancy. The rate of chromosome abnormality increases with the increase of maternal age and the history of live birth, and decreases with the increase of number of previous spontaneous abortion and IVF-ET pregnancy.

Abstract
To stipulate the rationale of spraying doses and to determine the safe interval period of boscalid suspension concentrate (SC), the degradation dynamics and residual levels were investigated in cucumber and soil using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Field trials were conducted according to Chinese Guideline on pesticide residue trials. Following application, the degradation kinetics was best ascribed to first-order kinetic models with half-life of 2.67-9.90 d in cucumber. Spraying boscalid SC at 1.5-fold the recommended dosage yield terminal residues, which are clearly lower than the maximum residue limit (MRL) established by China (MRL =5 mg.kg-1) in cucumber. At variance, the dissipation dynamics in soil did not fit to first-order kinetics and the half-life was more than 17 days, the finding which denotes that the degradation behavior of boscalid in soil proceeds slowly. It has therefore been shown that boscalid is safe for use on cucumbers under the recommended dosage.

Abstract
Objective: To investigate the relationship between donor chimerism and relapse after allogeneic hematopoietic stem cell transplantation (allo-HSCT) . Methods: The clinical data of 105 patients with acute myeloid leukemia (AML) who underwent allo-HSCT and recurrence-free survival>90 days from January 2010 to January 2019 were retrospectively analyzed. The bone marrow samples were collected at 15, 30, 60, 90, 180, 270, 360 days after transplantation. Donor chimerism was detected by single nucleotide polymorphism (SNP) -PCR. Results: Of the 105 patients, 43 cases were male and 62 cases were female, with a median age of 38 (16-60) years. Till April 2019, the median follow-up was 843 (94-3 261) days. Ninety days after transplantation, 18 cases relapsed, 33 cases died, and 72 cases survived. The 3-year overall survival (OS) rate was (66.8±5.1) %, and the recurrence-free survival (RFS) rate was (65.1±5.0) %. Pre-transplant disease status, pre-transplant minimal residual disease (MRD) , and 90 day post-transplantation chimerism were independent risk factors related to RFS. The risk of recurrence was significantly increased in patients with a donor chimerism rate ≤97.24% at 90 days after transplantation[HR=6.921 (95%CI 2.669-17.950) , P<0.001], which was considered as a sign of early relapse. Conclusion: SNP-PCR is an applicable method for detecting donor chimerism in patients after allo-HSCT. Chimerism rate equal or less than 97.24% at 90 days after transplantation predicts a higher risk of relapse.

Abstract
OBJECTIVE In this study, we retrospectively evaluated the therapeutic efficacy of China Children Leukemia Group-ALL2008 (CCLG-ALL 2008) protocol in pediatric patients with mixed-lineage leukaemia (MLL) gene rearrangement of acute lymphoblastic leukemia (ALL) to identify the prognostic factors. PATIENTS AND METHODS Six hundred and thirty-four patients with ALL were enrolled in this study between June 2008 and Dec 2014. High-risk group (HR) consisted of 217 cases, of which 28 cases were MLL related positive (first group), 22 cases were BCR/ABL positive (second group), and 167 cases were negative with MLL related or BCR/ABL (third group). The therapeutic efficacy was evaluated at the time points of day 8 (TP1), day 15 (TP2), day 33 (TP3) and 12th week (TP4) with the protocol, respectively. Overall-survival (OS) and relapse-free-survival (RFS) and treatment-related mortality (TRD) were analyzed as well. RESULTS The first group accounted for 4.4% of all patients. Compared with the second and third group, the first group had more cases younger than 2 years, with initial leukocytes ≥50×109/L, and poor response on TP2. Moreover, patients older than 2 years old had a good 5 years OS (84% ± 9% vs. 37% ± 20%, p<0.05) and RFS (84% ± 9% vs. 29% ± 17%, p<0.05). There were no significant differences in the recurrence rate, TRD, 5 years OS and RFS among three groups. For the first group, compared with good response to prednisone, patients with poor response to prednisone had a poor 5 years RFS (41% ± 17% vs. 81% ± 10%, p<0.05). Multivariate Cox regression analysis identified that RFS and OS were influenced by such factors as age, MLL fusion partners, and prednisone response (p<0.05). CONCLUSIONS Such factors as younger age than 2 years old, MLL/AF4 fusion gene, poor response to prednisone, or no complete remission (CR) on TP3 were poor prognostic parameters in predicting the outcome in childhood ALL with MLL gene rearrangement treated with CCLG-ALL 2008 protocol.

Abstract
OBJECTIVE Bladder cancer is the most prevalent genitourinary malignant disorder worldwide. We aimed to observe effects of high-glucose on bladder cancer proliferation and explore the associated mechanisms. MATERIALS AND METHODS Human bladder cancer cell line, T24, was divided into Blank, Control (Ctrl), 10 mmol/l, 20 mmol/l and 30 mmol/l group. T24 cell proliferation was evaluated by using multiple table tournament (MTT) assay and colony formation analysis, respectively. Quantitative Real-time PCR (qRT-PCR) assay was employed to examine mRNA expression of Wnt-5a and β-catenin. Meanwhile, Western blot assay was used to evaluate expression of Wnt-5a and β-catenin protein. The linear regression analysis was utilized to analyze correlation between Wnt-5a/β-catenin expression and T24 cell proliferation. RESULTS High-glucose significantly enhanced proliferation of T24 cells compared to that of Blank and Ctrl group (p < 0.05). High-glucose significantly promoted colony formation of T24 cells compared to that of Blank and Ctrl group (p < 0.05). High-glucose significantly up-regulated Wnt-5a mRNA and protein expression compared to that of Blank and Ctrl group (p < 0.01). High-glucose significantly increased β-catenin mRNA and protein expression compared to that of Blank and Ctrl group (p < 0.01). Effects of high-glucose on T24 cell proliferation were increased following with the enhanced glucose concentration. Wnt/β-catenin signaling pathway molecules were correlated with colony formation of T24 cells (p < 0.05). CONCLUSIONS High-glucose promoted the proliferation of T24 cells by activating the Wnt/β-catenin signaling pathway. This study would provide the novel targets for bladder cancer therapy.

Abstract
With the rapid developments in compact devices, the multi-function and reconfigurability of nanostructures are highly appreciated, while still very challenging. A majority of devices are usually mono-functional or hard to switch between different functions in one design. In this paper, we proposed graphene-wrapped core-shell nanowires to realize real-time reconfigurable sensors and nanoantenna by tuning the Fermi energies of graphene layers at the surfaces of core and shell, respectively. Owing to the electromagnetic coupling between the two graphene layer, two corresponding Fano resonances of scattering can arise in the Terahertz spectrum, which arises from the interference of bright modes and dark modes. Around the Fano resonances, the scattering can be considerably resonant (as an antenna) or suppressed (as a sensor). Interestingly, the field distributions are distinct at the suppressed scattering states for the two Fano resonances. The presented reconfigurable nanostructures may offer promising potentials for integrated and multi-functional electromagnetic control such as dynamic sensing and emission.

Abstract
Objective: To explore the clinical and prognostic values of TP53 gene mutation in patients with acute myeloid leukemia (AML) . Methods: A retrospective analysis of 265 newly diagnosed AML patients with next-generation sequencing (NGS) data in the Hematology Department of Changhai Hospital from January 2010 to January 2019 was performed. Mutation analysis was carried out by targeted sequencing technology including 200 hematological malignancy related genes. The association of TP53 mutation with clinical features was analyzed. Results: Alterations in TP53 were found in 20 (7.5%) patients, including 17 case (6.4%) of missense mutations, 2 cases (0.7%) of frame-shift deletion mutations and 1 case (0.4%) of splicing sites mutation. A total of 23 kinds of TP53 mutations were detected, most of them (16, 69.6%) were located in the DNA binding domain of exon 5-8, 4 in the DNA binding domain of exon 3-4, 2 in exon 10 and 1 in splice site, respectively. The median age of patients with TP53 alterations was higher than those without [52 (26-72) years old vs 45 (14-75) years old, P= 0.008]. The frequency of complex karyotypes was higher in patients with TP53 alterations than those without [45.0% (9/20) vs 6.1% (15/245) , P<0.001]. Median overall survival (OS) of patients with TP53 alterations was shorter than those without[14.1 (95%CI 6.78-21.42) months vs 31.4 (95%CI 13.20-49.59) months, P=0.029]. The OS of patients treated with "Decitabine + CAG" was superior than that of patients treated with "3 + 7" regimen [30.0 (95%CI 27.35-38.84) months vs 12.5 (95%CI 5.80-19.19) months, P=0.018]. Multivariate analysis indicated that TP53, DNMT3A and USH2A alterations, WBC ≥ 12.45×10(9)/L had negative impacts on OS. Conclusion: The frequency of TP53 mutation was 7.5% in our cohort. Most mutations were located in the DNA binding domain. TP53 alterations were strongly associated with older age, complex karyotype and shorter OS. Decitabine-based induction chemotherapy and hematopoietic stem cell transplantation may improve OS, more cases and/or multicenter randomized studies are needed for further confirmation.

Abstract
OBJECTIVE Chemokine (C-C motif) ligand 2 (CCL2) is a member of the CC subfamily, which displays chemotactic activity for monocytes and basophils. This molecule plays a very important role in many solid tumors and shows changes in the bone marrow microenvironment. However, its role in acute myeloid leukaemia (AML) is still unclear. MATERIALS AND METHODS In this study, we established a HL-60 cell line with CCL2 knockdown to explore its effect on leukemogenesis. Lentivirus with CCL2-knockdown was successfully constructed after screening effective CCL2 short hairpin RNA (shRNA) sequences and was transfected into HL-60 cells, which was further validated at the mRNA and protein levels by real-time polymerase chain reaction (PCR) and Western blotting, respectively. RESULTS Low expression of CCL2 significantly decreased HL-60 cell growth by increasing the cell arrest at G1 phase by 12% more than controls. We applied RNA sequencing technology to discriminate the gene expression profiles between the cells with CCL2 knockdown and the controls, and Cyclin D1 was selected for further experiments as its expression level was significantly downregulated, which was validated at the mRNA and protein levels. Cyclin D1 knockdown experiments showed that the cell proliferation rate was evidently decelerated, and cell cycle analysis also indicated a similar pattern for CCL2. CONCLUSIONS Our study revealed that Cyclin D1 is an effector that mediates CCL2's function in cell proliferation by blocking cells at G1 phase.

Abstract
Non-small cell lung cancer (NSCLC) is the most prevalent subtype of lung cancer histologically, and an increasing number of evidences have shown during the past years that long non-coding RNAs (lncRNAs) are involved in tumorigenesis. Here we found a long non-coding RNA, GATA2-AS1, repressing NSCLC cells proliferation via regulating GATA2. GATA2-AS1 gene is located at antisense strand of GATA2 on chromosome while GATA2-AS1 RNA interacts with GATA1 protein at promoter region of GATA2 and then inhibits its transcription. Moreover, GATA2-AS1 is transcriptionally repressed by MYC in NSCLC cells. To conclude, our study discovered the role of lncRNA GATA2-AS1 in human non-small cell lung cancer growth thus providing a potential target for lung cancer drugs.

Abstract
Vacuolar protein sorting 4 (Vps4) not only functions with its positive regulator vacuolar protein sorting 20-associated 1 (Vta1) in the multivesicular body (MVB) pathway but also participates alone in MVB-unrelated cellular processes. However, its physiological roles at the organism level remain rarely explored. We previously identified their respective homologues Bombyx mori Vps4 (BmVps4) and BmVta1 from the silkworm, a model organism for insect research. In this study, we performed fluorescence quantitative real-time PCR and Western blot to globally characterize the transcription and protein expression profiles of BmVps4 and BmVta1 during silkworm development and in different silkworm tissues and organs. The results showed that they were significantly up-regulated in metamorphosis, adulthood and embryogenesis relative to larval stages, and displayed a roughly similar tissue-and-organ specificity for transcriptions in silkworm larvae. Importantly, BmVps4 was down-regulated during the early period of the fifth instar, reaching the lowest level of transcription on Day 6, then up-regulated from Day 7 to the wandering, spinning and pupal stages, and down-regulated again in adulthood. Moreover, knocking down BmVps4 by RNA interference significantly inhibited silk gland growth, shortened spinning time, prolonged pupation, reduced pupal size and weight, and increased moth wing defects. Together, our data demonstrate the critical and broad requirements for BmVps4 in silkworm metamorphosis.

Abstract
BACKGROUND Neuroimaging studies have identified obesity-related differences in the brain's resting state activity. An imbalance between homeostatic and reward aspects of ingestive behaviour may contribute to obesity and food addiction. The interactions between early life adversity (ELA), the reward network and food addiction were investigated to identify obesity and sex-related differences, which may drive obesity and food addiction. METHODS Functional resting state magnetic resonance imaging was acquired in 186 participants (high body mass index [BMI]: ≥25: 53 women and 54 men; normal BMI: 18.50-24.99: 49 women and 30 men). Participants completed questionnaires to assess ELA (Early Traumatic Inventory) and food addiction (Yale Food Addiction Scale). A tripartite network analysis based on graph theory was used to investigate the interaction between ELA, brain connectivity and food addiction. Interactions were determined by computing Spearman rank correlations, thresholded at q < 0.05 corrected for multiple comparisons. RESULTS Participants with high BMI demonstrate an association between ELA and food addiction, with reward regions playing a role in this interaction. Among women with high BMI, increased ELA was associated with increased centrality of reward and emotion regulation regions. Men with high BMI showed associations between ELA and food addiction with somatosensory regions playing a role in this interaction. CONCLUSIONS The findings suggest that ELA may alter brain networks, leading to increased vulnerability for food addiction and obesity later in life. These alterations are sex specific and involve brain regions influenced by dopaminergic or serotonergic signalling.

Abstract
Biochemical, transgenic, and genetic complementation data demonstrate that three glutathione S-transferases are involved in the storage of anthocyanins, flavonols, and proanthocyanins in plant cells. Flavonoids are compounds in tea (Camellia sinensis) that confer the characteristic astringent taste of tea beverages; these compounds have numerous benefits for human health. In plant cells, flavonoids are synthesized in different locations within the cytoplasm and are then transported and finally stored in vacuoles. To date, the mechanism involved in the intracellular transport of flavonoids in tea has not been well elucidated. In this study, we report the functional characterization of three cDNAs encoding glutathione S-transferases (CsGSTs) of C. sinensis, namely, CsGSTa, CsGSTb, and CsGSTc. The expression profiles of CsGSTa and CsGSTb were positively correlated with the accumulation of flavonols, anthocyanins and proanthocyanins in tea tissues and cultivars. These three recombinant CsGSTs showed a high affinity for flavonols (kaempferol-3-O-glucoside and quercetin-3-O-glucoside) and anthocyanin (cyanidin-3-O-glucoside) in vitro but had no or weak affinity for epicatechin. In vivo, CsGSTa, CsGSTb and CsGSTc fully or partially restored the storage of anthocyanins and proanthocyanidins in transgenic tt19 mutants. Metabolic profiling revealed that the contents of anthocyanins, flavonols, and proanthocyanidins were increased in the transgenic petals of Nicotiana tabacum. Taken together, all data showed that CsGSTa, CsGSTb, and CsGSTc are associated with the storage of anthocyanins, flavonols, and proanthocyanins in C. sinensis cells.

Abstract
AIM Cholangiocarcinoma (CCA) is a highly malignant tumor found in the bile duct epithelial cells, and the second most common primary tumor of the liver. However, the pivotal roles of molecular biomarkers in oncogenesis of CCA are unclear. Therefore, we aim to explore the underlying mechanisms of progression and screen for novel prognostic biomarkers and treatment targets. METHOD The data of mRNA sequencing and clinical information of CCA patients in The Cancer Genome Atlas was analyzed by weighted gene coexpression network analysis (WGCNA). Modules and clinical traits were constructed according to Pearson's correlation analysis, and Gene Ontology and pathway enrichment analysis were applied. Hub genes of these modules were screened by intramodule analysis; Cytoscape with Search Tool for the Retrieval of Interacting Genes was utilized to visualize protein-protein interaction of these modules; hub genes of these modules were validated afterwards. Furthermore, the significance of these genes was confirmed by survival analysis. RESULTS Genes MRPS18A, CST1, and SCP2 were identified as candidate genes in the module, which was associated with clinical traits including pathological stage, histological grade, and liver function and which also affected overall survival of CCA patients. Nineteen hub genes were analyzed together and were associated with progression and prognosis of CCA. Survival analyses found that several of the multiple genes could serve as biomarkers to stratify CCA patients into low- and high-risk groups. CONCLUSION These candidate genes could be involved in progression of CCA, which could serve as novel prognostic markers and treatment targets. Moreover, most of them were first reported in CCA and deserve further research.

Abstract
Objective: To compare the difference of efficacy between traditional Hyper-CVAD/MA regimen and the adolescents inspired chemotherapy regimen, CH ALL-01, in treatment of adult Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph(+) ALL) . Methods: In this study we retrospectively analyzed 158 Ph(+) ALL patients receiving Hyper-CVAD/MA regimen (n=63) or CHALL-01 regimen (n=95) in our center and Changzheng hospital from January 2007 to December 2017, excluding patients with chronic myeloid leukemia in blast crisis. Tyrosine kinase inhibitor (TKI) was administered during induction and consolidation chemotherapy. Patients who underwent hematopoietic stem cell transplantation received TKI as maintenance therapy. Results: Of them, 91.1% (144/158) patients achieved complete remission (CR) after 1-2 courses of induction. CR rate was 90.5% (57/63) for patients in Hyper-CVAD/MA group and 91.6% (87/95) for patients in CHALL-01 group. There was no difference in CR rates between the two groups (χ(2)=0.057, P=0.811) . The last follow-up was June 2018. A cohort of 134 CR patients could be used for further analysis, among them, 53 patients received Hyper-CVAD/MA regimen and other 81 patients received CHALL-01 regimen. The molecular remission rates were significantly higher in CHALL-01 group (complete molecular response: 44.4%vs 22.6%; major molecular response: 9.9% vs 18.9%) (χ(2)=7.216, P=0.027) . For the patients in Hyper-CVAD/MA group, the 4-year overall survival (OS) was 44.81% (95%CI: 30.80%-57.86%) and the 4-year disease free survival (DFS) was 37.95% (95%CI: 24.87%-50.93%) . For patients received CHALL-01 regimen, the 4-year OS was 55.63% (95%CI: 39.07%-69.36%) (P=0.037) and 4 year DFS was 49.06% (95%CI: 34.24%-62.29%) (P=0.015) , while there was no significant difference in 4 year cumulative incidence of relapse (CIR) (P=0.328) or cumulative incidence of nonrelapse mortality (CI-NRM) (P=0.138) . The rate of pulmonary infection was lower in patients received CHALL-01 regimen compared with patients received Hyper-CVAD regimen (43.4% vs 67.9%, χ(2)=7.908, P=0.005) . Conclusions: Outcome with CHALL-01 regimen appeared better than that with the Hyper-CVAD/MA regimen in Ph(+) ALL, which has lower incidence of pulmonary infection, higher molecular remission rate and better OS and DFS.

Abstract
Objective: To explore the relationship between plasma amyloid-β (Aβ) and cognitive decline during 2 year follow-up in a population-based cohort in Xi'an rural areas. Methods: The study was conducted in Qubao village in Xi'an suburbs cognitively normal residents over 40 years old were recruited from October 2014 to March 2015 and given a face-to-face standardized interview. Mini-mental state examination (MMSE) was employed to evaluate the global cognitive function, and quantification of plasma Aβ was measured by sandwich enzyme-linked immunosorbent assay (ELISA) at baseline. Two years later, MMSE was tested at the end of study. Then logistic regression was performed to analyze the relationship between baseline Aβ and cognitive change during 2 year follow-up. Results: A total of 1 020 participants completed the study, among whom 223 subjects (21.9%) presented MMSE scores decline (defined as MMSE scores decreased ≥2 points). Compared with those without decline, participants in the MMSE decline group were older (P<0.001) and had lower education level (P<0.001), while gender, hypertension, hyperlipemia, diabetes mellitus and APOE genotype were not significantly different between two groups. One-way analysis of variance (ANOVA) showed that the MMSE score decline was slighter in the lower tertile of baseline Aβ(1)-40 compared with middle tertile (P=0.012), while MMSE decline were similar between different Aβ(1)-42 level groups and Aβ(1-42)/Aβ(1-40) ratio groups (P=0.758, P=0.671, respectively). Multivariable logistic regression analysis showed that MMSE scores in the lower baseline plasma Aβ(1-40) level declined more slowly (OR=0.565, 95%CI 0.379-0.845, P=0.005). However, the MMSE decline were also similar among different baseline plasma Aβ(1-42) levels groups and Aβ(1-42)/Aβ(1-40) ratio groups. Conclusion: Population with lower level of baseline plasma Aβ(1-40) manifests lower cognitive decline during 2 years, however further investigation on dynamics of plasma Aβ and long term follow up are needed.

Abstract
Objective: To evaluate the clinical effects of functional neck dissection (FND) and supraomohyoid neck dissection (SOND) in patients with cN0/N1 oral squamous cell carcinoma (OSCC). Methods: A total of 210 patients with stage cN0/N1 OSCC underwent FND and SOND between January 2012 and May 2015 were retrospectively reviewed, among which, 147 patients were male and 63 were female, with an age range of 23-82 years and mean age of (62.2±10.2) years. There were 112 and 98 patients in FND and SOND groups, respectively. The follow-up data included cervical lymph node metastasis, movement of shoulder joint, great auricular nerve function, recurrence rate of cervical lymph nodes. Results: There was no significant difference in gender, age, tumor location, T stage, N stage, histological grades between the two groups (all P>0.05). Compared to patients in FND group, the activities of shoulder joint and earlobe numbness improved significantly in SOND group. Of the 210 patients, 17 patients (8.1%) had cervical recurrence, with 9 patients (8.0%) in FND group and 8 patients (8.2%) in SOND group. No significant difference was observed for neck recurrence between the two groups (P=0.973). Conclusion: SOND can be safely performed in cN0 or cN1 OSCC patients, which avoids major complications of FND, and improves postoperative quality of life in those patients.

Abstract
Flavonoids are major polyphenol compounds in plant secondary metabolism. The hydroxylation pattern of the B-ring of flavonoids is determined by the flavonoid 3'-hydroxylase (F3'H) and flavonoid 3',5'-hydroxylase (F3'5'H). In this paper, one CsF3'H and two CsF3'5'Hs (CsF3'5'Ha and CsF3'5'Hb) were isolated. The phylogenetic tree results showed that F3'H and F3'5'Hs belong to the CYP75B and CYP75A, respectively. The Expression pattern analysis showed that the expression of CsF3'5'Ha and CsF3'5'Hb in the bud and 1st leaf were higher than other tissues. However, the CsF3'H had the highest expression in the 4th and mature leaf. The correlation analysis showed that the expression of CsF3'5'Hs is positively associated with the concentration of B-trihydroxylated catechins, and the expression of CsF3'H is positively associated with the Q contentration. Heterologous expression of these genes in yeast showed that CsF3'H and CsF3'5'Ha can catalyze flavanones, flavonols and flavanonols to the corresponding 3', 4' or 3', 4', 5'-hydroxylated compounds, for which the optimum substrate is naringenin. The enzyme of CsF3'5'Hb can only catalyze flavonols (including K and Q) and flavanonols (DHK and DHQ), of which the highest activities in catalyzing are DHK. Interestingly, The experiment of site-directed mutagenesis suggested that two novel sites near the C-terminal were discovered impacting on the activity of the CsF3'5'H. These results provide a significantly molecular basis on the accumulation B-ring hydroxylation of flavonoids in tea plant.

Abstract
Background Liquid biopsies based on blood samples have been widely accepted as a diagnostic and monitoring tool for cancers, but extremely high sensitivity is frequently needed due to the very low levels of the specially selected DNA, RNA, or protein biomarkers that are released into blood. However, routine blood indices tests are frequently ordered by physicians, as they are easy to perform and are cost effective. In addition, machine learning is broadly accepted for its ability to decipher complicated connections between multiple sets of test data and diseases. Objective The aim of this study is to discover the potential association between lung cancer and routine blood indices and thereby help clinicians and patients to identify lung cancer based on these routine tests. Methods The machine learning method known as Random Forest was adopted to build an identification model between routine blood indices and lung cancer that would determine if they were potentially linked. Ten-fold cross-validation and further tests were utilized to evaluate the reliability of the identification model. Results In total, 277 patients with 49 types of routine blood indices were included in this study, including 183 patients with lung cancer and 94 patients without lung cancer. Throughout the course of the study, there was correlation found between the combination of 19 types of routine blood indices and lung cancer. Lung cancer patients could be identified from other patients, especially those with tuberculosis (which usually has similar clinical symptoms to lung cancer), with a sensitivity, specificity and total accuracy of 96.3%, 94.97% and 95.7% for the cross-validation results, respectively. This identification method is called the routine blood indices model for lung cancer, and it promises to be of help as a tool for both clinicians and patients for the identification of lung cancer based on routine blood indices. Conclusions Lung cancer can be identified based on the combination of 19 types of routine blood indices, which implies that artificial intelligence can find the connections between a disease and the fundamental indices of blood, which could reduce the necessity of costly, elaborate blood test techniques for this purpose. It may also be possible that the combination of multiple indices obtained from routine blood tests may be connected to other diseases as well.

Abstract
OBJECTIVE β-arrestin (ARRB2) is a member of arrestin family and a negative regulatory protein of G-coupling receptor, which is closely associated with the pathogenesis of several autoimmune diseases. This study aimed to investigate the mechanism of the effect of ARRB2 on the damage of human umbilical vein endothelial cells (HUVECs), which is induced by angiotensin II (Ang II). MATERIALS AND METHODS ARRB2 at different concentration was used to interfere with the damage of HUVECs induced by Ang II or RNA interference technology to interfere with the expression of HUVECs followed by addition of Ang II to culture for 24 hours. Nitrate reduction method was used to measure the content of nitric oxide (NO) and radioimmunoassay was used to measure endothelin-1; Western blot assay was used to detect the expression of B-cell lymphoma-2 (Bcl-2), and flow cytometry was used to detect the intracellular level of reactive oxygen (ROS) and apoptosis of HUVECs. RESULTS Our study found that ARRB2 could significantly reduce the generation and release of ROS, endothelin-1 (ET-1), lactic dehydrogenase (LDH) of HUVECs induced by Ang II and promote the generation of NO, superoxide dismutase (SOD) and scavenging in a dose-dependent manner. On the contrary, when expression of ARRB2 was disturbed by siRNA, increased generation and release of ROS, ET-1, and LDH were observed with reduced generation of NO, SOD and scavenging. In addition, ARRB2 could reverse the apoptosis of HUVECs induced by Ang II and was related to upregulate the expression of Bax. CONCLUSIONS ARRB2 could protect the damage of HUVECs induced by Ang II and the mechanism was associated with upregulation of the expression of apoptosis and anti-apoptosis protein of Bcl-2.

Abstract
Objective: To investigate the role of piperine on the transformation of endothelial cells into fibroblasts. Methods: Cultured human umbilical vein endothelial cells (HUVECs, 4-6 passage) were used for the main experiments. The transformation models of endothelial cells into fibroblasts were induced by transforming growth factor β (TGF-β) stimulation. HUVECs were divided into 6 groups: control group, TGF-β group and 4 groups treated with various concentrations of piperine (1, 5, 10, 20 μmol/L). CKK-8 was used to detect cell proliferation. The CD31/α-smooth muscle actin (α-SMA) expression level was detected by fluorescent staining. The vascular endothelial cadherin (VE-cadherin)/vimentin expression was detected by immunofluorescence staining. RT-PCR was used detect the mRNA expressions of transformation markers. Western blot was used to detect the protein expression of snail and twist. Results: TGF-β increased HUVECs proliferation (P<0.05), which could be significantly inhibited by 10 and 20 μmol/L of piperine, but not by 1 and 5 μmol/L of piperine. Immunofluorescence results demonstrated that TGF-β increased HUVECs transformation to fibroblasts as shown by downregulated expression of endothelial markers CD31, VE-cadherin, and upregulated expression of α-SMA and vimentin, again, these effects could be attenuated by 10 and 20 μmol/L piperine. The expression levels of collagen type Ⅰ and type Ⅲ were significantly higher in TGF-β group than in control group (P<0.05), significantly lower in TGF-β+10 μmol/L piperine group and TGF-β+20 μmol/L piperine group than in TGF-β group (P<0.05).In addition, RT-PCR results showed that TGF-β increased mRNA expression of transformation markers (snail1, snail2, twist1, twist2), while 10 and 20 μmol/L of piperine could significantly downregulated the mRNA expressions of these markers. The protein expression levels of snail and twist were significantly higher in TGF-β group than in control group (both P<0.05), which was significantly lower in TGF-β+20 μmol/L piperine group than in TGF-β group (both P<0.05). Conclusions: Piperine can inhibit the transformation of endothelial cells into fibroblasts. This effect might be viewed as one of the potential mechanisms of reduced myocardial fibrosis post piperine treatment.

Abstract
Tea is a globally consumed non-alcohol beverage with great economic importance. However, lack of the reference genome has largely hampered the utilization of precious tea plant genetic resources towards breeding. To address this issue, we previously generated a high-quality reference genome of tea plant using Illumina and PacBio sequencing technology, which produced a total of 2,124 Gb short and 125 Gb long read data, respectively. A hybrid strategy was employed to assemble the tea genome that has been publicly released. We here described the data framework used to generate, annotate and validate the genome assembly. Besides, we re-predicted the protein-coding genes and annotated their putative functions using more comprehensive omics datasets with improved training models. We reassessed the assembly and annotation quality using the latest version of BUSCO. These data can be utilized to develop new methodologies/tools for better assembly of complex genomes, aid in finding of novel genes, variations and evolutionary clues associated with tea quality, thus help to breed new varieties with high yield and better quality in the future.

Abstract
Objective: To investigate the effect of cinnamaldehyde (CIN) on the inflammation and apoptosis on human umbilical vein endothelial cells (HUVECs) induced by lipopolysaccharide (LPS), and to explore the potential mechanisms. Methods: HUVECs were divided in to 8 groups: blank control group, LPS group, LPS+(low, medium, high) dose CIN groups and (low, medium, high) CIN groups. Cell cytotoxicity was determined by trypan blue staining, mRNA expression of the inflammatory factors was determined by RT-PCR,apoptosis was determined by TUNEL staining,the signal pathway was determined by Western blot. Results: (1) Cell viability:compared with the control group,cell survival rate was significantly lower in the LPS group (P<0.01), while the survival rates were all significantly higher in the 3 LPS+CIN groups than in the LPS group (all P<0.01) in a concentration-dependent manner. (2) The mRNA expression of the inflammation factors: compared with the control group, mRNA expression of the inflammation factors were all increased in the LPS group (all P<0.01),while the effect of LPS could be significantly reversed by cotreatment with CIN in a concentration-dependent manner (all P<0.01). Compared with control group, the mRNA expression of the inflammation factors in the LPS group were all enhanced in a time-dependent manner (0,6,12,24 h),which could be significantly downregulated by cotreatment with LPS+CIN (high dose) in a time-dependent manner. (3) Cell apoptosis: compared with the control group, the apoptosis rate was significantly higher in the LPS group (P<0.01), while this effect could be significantly reversed by the cotreatment with CIN (high dose) (P<0.01). (4) Signaling pathway: compared with the control group, the phosphorylation of iκBα, p65 in HUVECs treated with LPS were rapidly up-regulated compared with their corresponding total proteins and the expression of TLR4 (all P<0.01), while the degree of p-iκBα/iκBα, p-p65/p65 and TLR4 could be significantly suppressed by cotreatment with CIN (high dose) (all P<0.01). Conclusion: CIN can attenuate LPS induced inflammation and apoptosis in HUVECs, possibly by inhibiting the activation of NF-κB signaling pathway.

Abstract
OBJECTIVE To systematically review and assess the quality of guidelines on colorectal cancer screening worldwide to provide guidance for the development of high-quality colorectal cancer screening guidelines in mainland China. METHODS CNKI, WanFang Data, VIP, SinoMed, PubMed, Embase, and Web of Science were systematically searched to identify guidelines on colorectal cancer screening from inception to Jun. 20th, 2018, and so were some websites and major search engines about the development of the guidelines from the existing literature (search date: Aug. 3rd, 2018). Two experienced reviewers independently examined these abstracts and then extracted information, and the Appraisal of Guidelines for Research and Evaluation II (AGREE II) were used to evaluate the methodological quality of these guidelines by four well trained reviewers. RESULTS In this study, 46 guidelines published from 1994 to 2018 were finally included in our analysis from 10 countries and 5 regions, among which 5 were from mainland China. The quality of these guidelines was relatively high in domain 1 (scope and purpose) and domain 4 (clarity of presentation), and medium in domain 2 (stakeholder involvement). While in the other three domains (domain 3: rigour of development; domain 5: applicability; domain 6: editorial independence), the results were quite different among these guidelines. The quality of evidence-based guidelines (defined by the criteria based on World Health Organization guideline development handbook) was generally higher than that of the common guidelines. Existing guidelines from mainland China were not evidence-based guidelines, which were of low quality. CONCLUSION The colorectal cancer screening guidelines all over the world are generally large in number, low in quality, different in statements, and so are the guidelines in China. There are no evidence-based guidelines in mainland China, which cannot provide effective guidance for colorectal cancer screening, so we need to pay more attention to the establishment of guidelines with high quality and high credibility for colorectal cancer screening as well as for cancer screening based on the national condition, in order to provide reasonable guidance for practice in public health and improve the health conditions in our society.

Abstract
Pinoresinol/lariciresinol reductase (PLR), an NADPH-dependent reductase that catalyzes the sequential reduction of pinoresinol into secoisolariciresinol via Lariciresinol, can lead to the structural and stereochemical diversity of lignans. The relationship between substrate-selective reaction of PLR and sequence homology still remains unclear. In this study, we focused on the contribution of the variable region between PLRs in determining substrate selectivity. Here, two CsPLRs (CsPLR1 and CsPLR2) were identified in the tea plant (Camellia sinensis var. sinensis cv. Shuchazao). In vitro enzymatic assays showed that CsPLR1 could convert (+)- and (-)-pinoresinol into lariciresinol or secoisolariciresinol, whereas CsPLR2 catalyzed (+)-pinoresinol enantioselectively into (-)-secoisolariciresinol. Homology modeling and site-directed mutagenesis were used to examine the role of a variable loop in catalysis and substrate selectivity. The L174I mutant in CsPLR1 lost the capacity to reduce either (+)- or (-)-pinoresinol but retained the ability to catalyze the reduction of (-)-lariciresinol. These findings provide a basis for better understanding of the substrate-selective reaction of PLR.

Abstract
Vascular patches are commonly applied in tissue repair and reconstruction in congenital cardiac surgery. However, the currently available patch materials are inappropriate to be used in the pediatric population due to their lack of supporting tissue growth potential. In our study an active patch material was developed by seeding pediatric patient's bone marrow stem cells on a decellularized aortic extracellular matrix (ECM) scaffold. The patch was then implanted to repair abdominal aorta defects of nude rats. Two months after implantation, tissue remodeling, vascular cell regeneration, and cellular integration were investigated using histology and fluorescent staining. Histology demonstrated infiltration of host cells and formation of organized cell layers as well as intact collagen and elastic fibers inside the patch material. Immunofluorescence indicated regeneration of endothelial and smooth muscle cells. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) identified multiple vascularization-promoting components and growth factors in decellularized aortic ECM scaffold. These results demonstrated growth potential and suitability of human derived tissue-engineered patch for vascular reconstruction, and thus, it might be considered in the future as treatment option in pediatric patients.

Abstract
Background: The use of improvizational theater ("improv") in health professional education ("medical improv") is an emerging field. However, optimal curricular design features and learning outcomes have not yet been systematically described. Objective: To synthesize evidence on learning outcomes and curricular design elements of improvizational theater training in health professions education. Methods: A literature search with keywords "Improv" and "Improvisational Theatre" was undertaken in January 2016 in Ovid MEDLINE, CINHAL, EMBASE, SCOPUS, Web of Science, and ERIC, with an accompanying gray literature search. Four authors coded and achieved consensus on themes relating to curricular design elements and learning outcomes, which were mapped onto the CanMEDS framework. Results: Seven articles met inclusion criteria. Key curricular design features included (i) facilitators with dual clinical and theater expertise; (ii) creating a low-stakes environment; and (iii) engaging in debrief to highlight clinical relevance. Improv curricula were found to impact most CanMEDS roles, including: Medical Expert (comfort with uncertainty); Leader (team management); Scholar (feedback, self-reflection); Communicator (empathy, active listening, non-verbal communication); Collaborator (culture of trust); and Professional (resiliency and confidence). Mechanisms by which improv may promote acquisition of these professional competencies, and the utility of improv in areas such as interprofessional team development, leadership, and wellness and resiliency are discussed.

Abstract
Objective: To investigate the effect of dietary control combined with different exercise modes on plasma vaspin, irisin, and metabolic parameters in patients with non-alcoholic fatty liver disease (NAFLD) through a randomized open parallel-controlled study. Methods: The patients aged 30-65 years who visited Tianjin Third Central Hospital from January 2013 to December 2014 and were diagnosed with NAFLD by liver ultrasound and fat content determination were screening, and 474 patients were enrolled in this randomized controlled trial and divided into aerobic exercise group, resistance exercise group, and control group. All patients received dietary intervention. The three groups were compared in terms of biochemical parameters, fat content, NFS score, energy metabolic parameters, body composition index, and levels of vaspin and irisin at baseline and after 6 months of intervention. SPSS 19.0 was used for statistical analysis. The t-test, the Mann-Whitney U test, the chi-square test, and an analysis of variance were used for comparison between groups. The multiple imputation method was used for missing data, and the results were included in the intention-to-treat analysis. Results: There were no significant differences in age, sex, anthropometrical parameters, and biochemical parameters between the three groups at baseline. Compared with dietary control alone, aerobic exercise and resistance exercise helped to achieve significant reductions in waist circumference, diastolic pressure, percentage of body fat, volatile fatty acid, fasting blood glucose, homeostasis model assessment of insulin resistance, triglyceride, low-density lipoprotein cholesterol, free fatty acid, uric acid, alanine aminotransferase, and liver fat content after 6 months of intervention (P < 0.05). The aerobic exercise group had a significant increase in non-protein respiratory quotient and significant reductions in body mass index and aspartate aminotransferase after intervention, as well as a significant increase in resting energy expenditure and significant reductions in abdominal fat ratio and total cholesterol after 6 months of resistance exercise (P < 0.05). The aerobic exercise group and the resistance exercise group had a significant reduction in vaspin and a significant increase in irisin after intervention (P < 0.05), and the resistance exercise group had significantly greater changes in these two adipokines than the aerobic exercise group (P < 0.05). Conclusion: Exercise therapy is an effective method for the treatment of metabolism-associated diseases, and a combination of resistance and aerobic exercises is more reasonable and effective in clinical practice. As a relatively safe exercise mode, resistance exercise can also effectively improve the metabolic state of NAFLD patients.

Abstract
Objective: To investigate MRI features of lower limbs in patients with facioscapulohumeral dystrophy(FSHD). Methods: The clinical manifestations, myopathological findings and MRI images of 5 FSHD patients were studied retrospectively from June 2016 to December 2017 at Department of Neurology, Henan Provincial People's Hospital, 3 of which had a family history. Analysis of T(1)WI images enabled us to describe muscle fatty infiltration and STIR images to describe muscle edema. Each muscle was scored according to its fatty degeneration (fat replacement score range from 0-4). Results: The 5 patients were all asymmetrically involved. At the thigh level, the hamstrings were more affected than anterior muscles in 4 patients, and anterior muscles were more affected than hamstrings in only 1 patient. The most affected thigh muscles were usually the adductor magnus, semimembranosus, semitendinosus, femoral biceps long head and vastus medialis muscles (average fat replacement score of each muscle was more than 3). The calves were less affected than thighs.The average fat replacement score of the calf muscles was 1.0 for soleus, 0.9 for medial gastrocnemius, 0.8 for tibialis anterior, and 0.4 for lateral gastrocnemius. There was no fatty infiltration in peroneus and tibialis posterior. 4 out of 5 patients had edema in the lower limb muscles. Conclusion: Asymmetric involvement is a definitely helpful clue suggesting FSHD, and edema is a common phenomenon. At the thigh level, no unique imaging pattern can be highlighted in all the FSHD patients, overall, the hamstring, adductor magnus and vastus medialis are usually the most severely affected muscles. The calf muscles are less affected than the thigh muscles or spared. Soleus, medial gastrocnemius, and tibialis anterior are preferentially involved at the calf level.

Abstract
Implantable neural probes that are mechanically compliant with brain tissue offer important opportunities for stable neural interfaces in both basic neuroscience and clinical applications. Here, we developed a Neurotassel consisting of an array of flexible and high-aspect ratio microelectrode filaments. A Neurotassel can spontaneously assemble into a thin and implantable fiber through elastocapillary interactions when withdrawn from a molten, tissue-dissolvable polymer. Chronically implanted Neurotassels elicited minimal neuronal cell loss in the brain and enabled stable activity recordings of the same population of neurons in mice learning to perform a task. Moreover, Neurotassels can be readily scaled up to 1024 microelectrode filaments, each with a neurite-scale cross-sectional footprint of 3 × 1.5 μm2, to form implantable fibers with a total diameter of ~100 μm. With their ultrasmall sizes, high flexibility, and scalability, Neurotassels offer a new approach for stable neural activity recording and neuroprosthetics.
