Abstract
Background: To evaluate the relationship between hemorrhoids and Hashimoto's thyroiditis (HT). Methods: Using Taiwan's Longitudinal Health Insurance Database, we compared the incident risk of HT between the study cohort (comprising patients with hemorrhoids) and the comparison cohort (comprising patients without hemorrhoids). Both cohorts were followed from index date until the date of HT diagnosis, withdrawal from the National Health Insurance program, or the end of 2015. Results: The study cohort and comparison cohort comprised 6,486 patients with hemorrhoids and 25,944 patients without, respectively. The mean follow-up time was ~3 years. The incidence rate of HT in the study cohort was 5.37 per 1,000 person-years, which was higher than that of the control cohort (2.46 per 1,000 person-years). The risk of developing HT in the study cohort was 2.06 times (95% confidence interval [CI] = 1.02, 4.19) higher than that in the comparison cohort. Conclusion: In our study, patients with hemorrhoids could be at increased risk of HT compared with patients with other comorbidities of HT, such as cardiovascular disease.

Abstract
Merons which are topologically equivalent to one-half of skyrmions can exist only in pairs or groups in two-dimensional (2D) ferromagnetic (FM) systems. The recent discovery of meron lattice in chiral magnet Co8Zn9Mn3 raises the immediate challenging question that whether a single meron pair, which is the most fundamental topological structure in any 2D meron systems, can be created and stabilized in a continuous FM film? Utilizing winding number conservation, we develop a new method to create and stabilize a single pair of merons in a continuous Py film by local vortex imprinting from a Co disk. By observing the created meron pair directly within a magnetic field, we determine its topological structure unambiguously and explore the topological effect in its creation and annihilation processes. Our work opens a pathway towards developing and controlling topological structures in general magnetic systems without the restriction of perpendicular anisotropy and Dzyaloshinskii–Moriya interaction. A meron is one half of a skyrmion but whether a single meron pair can be created and stabilized remains a challenging question. Here, Gao et al. develop a method to create and stabilize individual pairs of merons in a continuous Py film by local vortex imprinting from Co disks.

Abstract
BACKGROUND/AIM C-Reactive protein (CRP) is a common marker of inflammation. Elevated CRP levels have been associated with increased risk of development of type 2 diabetes mellitus (T2DM). This study aimed to evaluate the association of CRP gene polymorphisms with early-onset T2DM and the effect of genetic variants on CRP level. MATERIALS AND METHODS In total, 948 individuals with early-onset (n=271) or late-onset (n=677) T2DM were enrolled in the study. Five single-nucleotide polymorphisms (SNPs) in the CRP gene, namely rs3093077, rs2808630, rs1800947, rs11265263, and rs11265265, were selected for genotyping, and CRP levels were measured. RESULTS Genotypic, allelic, and haplotype frequencies of these five SNPs were not significantly different between patients with early- and those with late-onset. T2DM Higher serum CRP levels were independently associated with the C-allele of rs3093077 and T-allele of rs11265265 (p<0.001). Furthermore, the C-allele of rs3093077 was associated with higher CRP level in both early- (p=0.016) and late-onset (p<0.001) T2DM. CONCLUSION CRP gene variants may contribute to the risk of early-onset T2DM by affecting the serum CRP level.

Abstract
目的 探讨成人急性淋巴细胞白血病(ALL)患者首疗程诱导治疗结束时微小残留病(MRD1)检测对自体造血干细胞移植(auto-HSCT)预后的意义。 方法 回顾性分析2006年2月1日至2017年4月30日行auto-HSCT的87例有流式细胞术MRD1检测结果的ALL患者临床资料,分析MRD1与ALL患者auto-HSCT后复发、生存的关系。 结果 26例(29.9%)ALL患者MRD1阳性。高危免疫表型比例在MRD1阳性组显著高于MRD1阴性组(34.6%对14.5%,P=0.038),初诊时年龄、性别、谱系(T/B)、免疫表型(标危/高危)、高白细胞计数(B-ALL>30×109/L或T-ALL>100×109/L)比例、伴高危染色体/基因比例、第1次完全缓解到移植的时间、预处理方案在MRD1阴性组和阳性组中差异均无统计学意义(P值均>0.05)。MRD1阴性患者、MRD1阳性患者的5年无白血病生存(LFS)率分别为75.7%、29.6%(P<0.001),总生存(OS)率分别为72.7%、47.3%(P=0.004)。多因素分析结果显示MRD1阳性是影响患者OS的独立危险因素(HR=3.007,95% CI 1.256~7.200,P=0.013),MRD1阳性和高危免疫表型是影响患者LFS的危险因素(HR=3.986,95% CI 1.813~8.764,P=0.001;HR=2.981,95% CI 1.373~6.473,P=0.006)。 结论 auto-HSCT不能逆转MRD1阳性患者的不良预后。MRD1阴性且在强化治疗中持续保持阴性患者可选择auto-HSCT治疗。

Abstract
Objective: To investigate the clinical status of lymphoid tissue neoplasms patients with bacteria bloodstream infections, bacteriology and drug susceptibility results, and provide the basis for rational clinical anti-infection option. Methods: A retrospectively analysis of clinical data and bacterial susceptibility test results of patients with bacteria bloodstream infections from September 2010 to December 2014 was conducted. Results: A total of 134 cases including 107 patients with bloodstream infections were enrolled. 84 cases were male, 50 cases were female, the median age was 31 (12-71) years old. 112 cases were agranulocytosis, and 106 cases were severe agranulocytosis (ANC<0.1×10(9)/L) . 27 cases underwent hematopoietic stem cell transplantation, 100 cases received chemotherapy[33 cases with VD (I) CP±L (vincristine+daunorubicin/idarubicin + cyclophosphamide + prednison±asparaginasum) induction chemotherapy, 41 cases with intensive chemotherapy of Hyper-CVAD/MA or MA (mitoxantrone+cytarabine) , 26 cases with other chemotherapy regimens], and 7 cases were infected without chemotherapy. 10 patients discharged from hospital owing to treatment abandoning, 120 cases were cured through anti-infective therapy, 2 patients died of bacteria bloodstream infections, 1 patient died of sudden cardiac, and 1 patient died of GVHD after allogenic hematopoietic stem cell transplantation. A total of 144 strains were isolated, including 108 strains (75.0%) of Gram-negative bacteria and 36 strains (25.0%) of Gram-positive cocci. The susceptibility of Gram-negative bacteria to the carbapenems was 98.00%, and the adjustment treatment rate of carbapenems was 3.0%. The susceptibility of Gram-negative bacteria to the other antibiotics was 60.30%, and the adjustment treatment rate was 90.5%. The susceptibility of Grampositive cocci to the carbapenems was 49.3%, and to glycopeptides and linezolid was 100.0%. Comparing all patients'empirical use of antimicrobial agents with the drugs susceptibility results of blood cultures, 80.1% of the patients'initial drug selection was sensitive. Conclusion: The lymphoid neoplasms patients experienced bacteria bloodstream infections most often after receiving the chemotherapy regimens of treating acute lymphoblastic leukemia. The majority type of bacteria was Gram-negative bacteria. Drug susceptibility test showed that susceptibility of Gram-negative bacteria to the carbapenems was the highest, and the treatment adjustment rate was obviously lower. The susceptibility of Gram-positive cocci to glycopeptides and linezolid was high, and which could be applied to the patients with Gram-positive cocci sepsis on basis of susceptibility results in general.

Abstract
Objective: To analyze the influence of simulation mouse use motion under different wrist forcing postures on median nerve, tendons and ligaments in the carpal tunnel. Methods: From June to November in 2017, a total of 49 healthy volunteers [aged from 18 to 27 years, 24 males (48 cases of hands) and 25 females (50 cases of hands)] were selected in the Institute of Digitized Medicine and First Affiliated Hospital of Wenzhou Medical University.Three hand postures of the volunteers were simultaneously and continuously measured by using LOGIQ E9 ultrasonic diagnostic apparatus and Zebris foot pressure distribution measurement system.Seventeen parameters of nerves, tendons and ligaments in carpal tunnel were observed under natural (0 N), and two forced (25 and 50 N) states.Double factor variance analysis was performed with generalized estimating equation (GEE). Results: With increasing pressure (0, 25 and 50 N) of hand postures, the distance between median nerve and transverse carpal ligament were all less than 0.2 cm.The differences in both the distance between median nerve and flexor pollicis longus under the hand pressure changes or under the hand posture changes and the top angle of a triangle composed of median nerve, flexor pollicis longus and flexor digitorum superficialis group under the hand pressure changes or under the hand posture changes were all significant under the GEE analysis (all P<0.01). There were no significant changes in all other structural parameters in the carpal tunnel with the increasing of hand pressure (all P>0.05). Conclusions: The influence of the transverse carpal ligament to the median nerve belongs to the mechanism of pressure-induced irritation damage.The influence of flexor pollicis longus to median nerve belongs to the mechanism of tension-induced irritation damage.The influence of flexor digitorum superficialis to median nerve belongs to the mechanism of mixed shear irritation damage.

Abstract
Objective: To investigate the long-term efficacy and prognostic factors of pediatric relapsed Wilms tumor (WT) after retreatment. Method: Sixteen children in Shanghai Children's Medical Center with relapsed Wilms tumor were enrolled consecutively in this study between April 2006 and June 2016. All patients were diagnosed according to pathology, imaging and medical and surgical oncologist's assistance. Relapse treatment included surgical excision, chemotherapy and selective radiation therapy. The clinical features, long-term outcomes and prognostic factors of patients were analyzed retrospectively.Survival data were analyzed by Kaplan-Meier.Log-Rank analysis was used for univariate analysis. Result: One case was excluded because of giving up the therapy even though no disease progress was identified. A total of 15 cases (5 males and 10 females) were included in this study. The median age at diagnosis was 3.8 years (range 0.5-9.1 years). The tumor staging at diagnosis included one case of stageⅠ, 7 cases of stageⅡand 7 cases of stage Ⅲ. Among cases of stage Ⅲ, 6 cases had radiation therapy history. The pathology of all patients' recurrent tumor was favorable histology (FH). The median follow-up time was 34.6 months (range 12.5-132.7 months) until March 21, 2017. The time from initial diagnosis to relapse was 7.9 months (range 3.1-17.9 months). Four cases experienced local recurrence, 9 cases relapsed with metastases (6 cases in lungs, 2 in livers, 1 in mediastinum) and 2 cases relapsed in both local site and with metastases. Except to 2 cases received irregular retreatment, 13 cases received regimen I (doxorubicin, vincristine, epoposide and cyclophosphamide for 25 weeks) as relapsed chemotherapy. Five cases received autologous bone marrow transplantation (ABMT). Until the last follow-up, 8 cases achieved continuous complete remission (range 6.7-104.3 months), 3 cases had relapse again or progressing and 4 cases died. The estimated 5-year overall survival (OS) rate and event free survival (EFS) rate were (70±15)% and (52±15)%. According to whether received ABMT or not, the 5-year EFS rate were 51% and 53%. According to whether relapsed within 6 months after diagnosis or not, the 5-year EFS rate were 38% and 56% respectively. Conclusion: The 5-year EFS rate of pediatric relapsed FH WT have reached above 50% by multi-disciplinary treatment in our experience and we encourage patients and doctors to receive retreatment.

Abstract
Objective: To evaluate the consistency in detection of T790M mutation of epidermal growth factor receptor gene (EGFR) in plasma and tumor samples of patients with lung adenocarcinoma. Methods: The tumor tissues or cytological specimens of 12 patients with operable lung adenocarcinoma(stage Ⅰ-ⅢA) and 100 patients with advanced stage ⅢB-Ⅳ lung adenocarcinoma were collected, among which 11 patients showed acquired resistance for gefitinib (11/100). In the same period, peripheral blood samples were collected from all patients and 50 healthy volunteers. Amplification refractory mutation system (ARMS) was used to detect EGFR mutations in tumor specimens. Next Generation Sequencing(NGS) based circulating single-molecule amplification and resequencing technology (cSMART)was performed to quantitatively detect the EGFR mutations in circulating tumor DNA (ctDNA) from plasma specimens. Results: The sensitivity, specificity and concordance rate of EGFR T790M mutation between plasma and tissue specimens from 100 advanced stage patients were 50.0%, 72.9% and 72.0%, respectively. For L858R mutation and exon 19 deletion mutations, the above mentioned sensitivity, specificity and concordance rate were 91.7%, 100.0%, and 98.0%, as well as 79.2%, 100.0% and 95.0%, respectively. The L858R mutation and exon 19 deletion mutations were not detected in plasma of 50 healthy volunteers, whereasT790M mutation(1.0±0.0 copies) was found in 7 individuals(7/50, 14.0%). Similarly, in 12 resectable patients, 4 (4/12, 33.3%) T790M mutations were found in plasma (1.2±0.2 copies), but no L858R mutation and 19 exon deletion mutations. In comparison, 28.0% of patients with advanced lung adenocarcinoma (28/100)had detectable T790M mutation in plasma with copy numbers (34.0±22.7 copies). Furthermore, the copy numbers of T790M were 268.2±119.9 in plasma of 5 cases with acquired gefitinib-resistance. Conclusions: In patients with advanced stages of lung adenocarcinoma, the detection of T790M mutation in plasma and tumor specimens is low. The T790M mutation also exists in the plasma of some healthy controls, suggesting that T790M mutation participates in EGFR signaling pathway and it might function in healthy population.

Abstract
A series of core/shell nanoparticle organic/inorganic hybrid materials (NOHMs) with different weight ratios of two components, consisting of multi-walled carbon nanotubes (MWCNTs) and silicon dioxide (SiO2) as the core were synthesized. The NOHMs display a liquid-like state in the absence of solvent at room temperature. Five NOHMs were categorized into three kinds of structure states based on different weight ratio of two components in the core, named the power strip model, the critical model and the collapse model. The capture capacities of these NOHMs for CO2 were investigated at 298 K and CO2 pressures ranging from 0 to 5 MPa. Compared with NOHMs having a neat MWCNT core, it was revealed that NOHMs with the power strip model show better adsorption capacity toward CO2 due to its lower viscosity and more reactive groups that can react with CO2. In addition, the capture capacities of NOHMs with the critical model were relatively worse than the neat MWCNT-based NOHM. The result is attributed to the aggregation of SiO2 in these samples, which may cause the consumption and hindrance of reactive groups. However, the capture capacity of NOHMs with the collapse model was the worst of all the NOHMs, owing to its lowest content of reactive groups and hollow structure in MWCNTs. In addition, they presented non-interference of MWCNTs and SiO2 without aggregation state.

Abstract
Objective: To investigate the characteristics of lower airway abnormalities in allergic rhinitis(AR) patients without asthma. Methods: Between June 2008 and December 2012, 377 consecutive AR patients and 264 healthy subjects were recruited. All subjects underwent meticulous history taking, nasal examination, allergen skin prick test, blood routine test, serum total immunoglobin E assay, induced sputum cell count and differentials, measurement of fractional exhaled nitric oxide (FeNO) and bronchial challenge test. Results: The positive rates in AR patients was 12.2%(46/377) for bronchial provocation test, 49.2%(185/377) for FeNO, 39.0%(147/377) for sputum eosinophilia, 15.6%(40/377) for peripheral blood eosinophilia and 55.4%(209/377) for increased serum total IgE levels, which were consistently and statistically higher than those of healthy controls(P<0.01). The levels of FeNO [35.0 (21.8, 65.9)ppb], induced sputum eosinophil percentage [2.0 (0.0, 7.5)%], peripheral blood eosinophil percentage [2.9 (1.8, 4.5)%] and serum total IgE [178.4 (63.1, 384.0)kU/L] in AR patients were also higher(P<0.01). Compared with healthy controls, patients with AR demonstrated lower levels of FEV1/FVC%, MMEFpred%, MEF75 pred%, MEF25pred% (all P<0.05). Statistical analysis showed that FeNO, ratio of induced sputum eosinophil percentage and peripheral blood eosinophil percentage had significant correlations with each other(P<0.01), the r value being 0.247, 0.235, 0.355 respectively. Conclusion: AR without asthma is characterized by lower airway inflammation, small airway impairment and bronchial hyperreactivity, features similar to those of asthma.

Abstract
Objective: To investigate the efficacy and the prognostic factors in pediatric hepatoblastoma according to the standard diagnostic and therapeutic regimen. Method: Eighty-four consecutive patients were enrolled in this study between June 2000 and June 2015. Diagnosis and staging was decided by the multi-disciplinary team including oncologists, surgeons, pathologists and sub-specialized radiologists refering to protocol of Children's Oncology Group(COG) and International Society of Pediatric Oncology Liver Tumor Study Group (SIOPEL) in a case observational study. Univariate analysis was tested by the log-rank and multivariate analysis by COX regression. All consecutive cases were divided into low risk group and high risk group according to grouping criteria. Complete remission was defined as both imaging negative and α fetoprotein (AFP) normalization. Retrospective analysis was performed in clinical features, long-term outcomes and prognostic factors. Result: Ten patients were excluded because of giving up after less than or equal to three cycles of treatment. A total of 74 cases were included in this study; 45 males and 29 females. The median age at diagnosis was 1.7 years(range 0.2-14.8 years). Untill August 30, 2016, the median follow-up time was 24.2 months (range 4.1-135.3 months); 59 cases achieved complete remission.The estimated five years overall survival (OS) and event free survival(EFS) were 90%(68/74)and 72%(58/74). AFP could be normalized after 5 circles of treatment or 2 circles of postoperation.In univariate analysis , the five years OS and EFS in low risk group were both 100%(18/18), and those in high risk group were 88%(50/56)and 68%(40/56), respectively. The five years OS rates were 75%(15/19) and 95%(53/55) in patients with or without distant metastasis (P=0.016). After 3 cycles of chemotherapy post tumor resection, we divided these patients into 2 groups according to AFP recover or not, the five years OS were 100%(43/43)and 81%(22/26), respectively (P=0.011). Conclusion: The result of this protocol is reasonable when comparing with other worldwide research. Except for staging, metastasis, pathological subtypes, postoperative AFP recover or not is a prognostic factor after 3 cycles of chemotherapy.

Abstract
The frequency (A), a novel in silico parameter, was developed by calculating the ratio of the number of truncated peptides with Xaa-proline and Xaa-alanine to all peptide fragments from a protein hydrolyzed with a specific protease. The highest in vitro DPP-IV inhibitory activity (72.7%) was observed in the hydrolysate of sodium caseinate by bromelain (Cas/BRO), and the constituent proteins of bovine casein also had relatively high A values (0.10-0.17) with BRO hydrolysis. 1CBR (the <1 kDa fraction of Cas/BRO) showed the greatest in vitro DPP-IV inhibitory activity of 77.5% and was used for in vivo test by high-fat diet-fed and low-dose streptozotocin-induced diabetic rats. The daily administration of 1CBR for 6 weeks was effective to improve glycaemic control in diabetic rats. The results indicate that the novel in silico method has the potential as a screening tool to predict dietary proteins to generate DPP-IV inhibitory and antidiabetic peptides.

Abstract
Prolyl endopeptidase (PEP) has been associated with neurodegenerative disorders, and the PEP inhibitors can restore the memory loss caused by amnesic compounds. In this study, we investigated the PEP inhibitory activity of the enzymatic hydrolysates from various food protein sources, and isolated and identified the PEP inhibitory peptides. The hydrolysate obtained from sodium caseinate using bromelain (SC/BML) displayed the highest inhibitory activity of 86.8% at 5 mg mL(-1) in the present study, and its IC50 value against PEP was 0.77 mg mL(-1). The F-5 fraction by RP-HPLC (reversed-phase high performance liquid chromatography) from SC/BML showed the highest PEP inhibition rate of 88.4%, and 9 peptide sequences were identified. The synthetic peptides (1245.63-1787.94 Da) showed dose-dependent inhibition effects on PEP as competitive inhibitors with IC50 values between 29.8 and 650.5 μM. The results suggest that the peptides derived from sodium caseinate have the potential to be PEP inhibitors.

Abstract
OBJECTIVE To investigate the clinical characteristics, treatment and prognosis of primary penoscrotal extra-mammary Paget's disease (PSPD). METHODS The clinical and pathological data of 22 cases of primary PSPD were retrospectively reviewed. Survival rate of the overall patients, the invasive patients, and the patients with positive surgical margin or negative surgical margin were analyzed with Kaplan-Meier survival curve method. RESULTS Among all the patients with primary PSPD, the median age of onset was 64.5 (39-84) years, the median time of disease duration was 40 (2-300) months, and the median long diameter of lesion was 4.75 (1-10) cm. In the study, 12 patients (54.5%) were in pathological stage A1, 6 patients (27.3%) were in pathological stage A2, and 4 patients (18.2%) were in pathological stage B. Scrotum and penile of most patients (n=12, 54.5%) were involved, 5 patients (22.7%) were scrotum only, and 5 patients (22.7%) were penile only. Erythema (n=18, 81.8%), itchiness (n=16, 72.7%), ulcerate (n=12, 54.5%), exudation (n=11, 50.0%), and pain (n=4, 18.2%) were the major manifestations. All the patients with primary PSPD were treated with wide surgical excision. The rate of invasive patients was 77.3% (n=17). Of them, 6 patients had positive surgical margin. The surgical margins of non-invasive patients were all negative. Twelve patients exhibited local recurrence or/and metastases, and the status of surgical margins (P=0.015) and the depth of invasion (P=0.010) were important risk factors. Inguinal lymph nodes were generally involved. The difference of the delay of diagnosis between metastasis and non-metastasis was significant (P=0.040). The 5-year survival rates of the overall and invasive patients were 33.7% and 27.9%, respectively. The patients with positive surgical margin had poor prognosis. CONCLUSION Primary PSPD, with the characteristics of long duration, high invasive tendency and high incidence of local recurrence or metastases, generally occurs in the elderly. Surgery should be performed at first. The delay of diagnosis, positive surgical margins and the involvement of inguinal lymph node are important risk factors. Biopsy, frozen section and inguinal lymph node biopsy (ILNB) can standardize diagnosis and treatment.

Abstract
In our previous study, Atlantic salmon skin gelatin hydrolysed with flavourzyme possessed 42.5% dipeptidyl-peptidase (DPP)-IV inhibitory activity at a concentration of 5 mg mL(-1). The oral administration of the hydrolysate (FSGH) at a single dose of 300 mg per day in streptozotocin (STZ)-induced diabetic rats for 5 weeks was evaluated for its antidiabetic effect. During the 5-week experiment, body weight increased, and the food and water intake was reduced by FSGH in diabetic rats. The daily administration of FSGH for 5 weeks was effective for lowering the blood glucose levels of diabetic rats during an oral glucose tolerance test (OGTT). After the 5-week treatment, plasma DPP-IV activity was inhibited; the plasma activity of glucagon-like peptide-1 (GLP-1), insulin, and the insulin-to-glucagon ratio were increased by FSGH in diabetic rats. The results indicate that FSGH has the function of inhibiting GLP-1 degradation by DPP-IV, resulting in the enhancement of insulin secretion and improvement of glycemic control in STZ-induced diabetic rats.
