Abstract
Carbon nanotubes and their composite thermoelectric (TE) materials have significant advantages in supplying power to flexible electronics due to their high electrical conductivity, excellent flexibility, and facile preparation technology. In this work, stable n-type silver ammonia-polyethyleneimine/single-walled carbon nanotube ([Ag(NH3)2]+-PEI/SWCNT) composite films were facilely prepared by solution blending and vacuum-filtration methods. The results demonstrate that light silver ammonia doping optimizes the carrier concentration and carrier mobility of the composite film, and a maximum power factor (PF) of [Ag(NH3)2]+-PEI/SWCNT of 91.9 μW m-1 K-2 was obtained, which is higher than that of PEI/SWCNT (70.0 μW m-1 K-2). Furthermore, when the composite films were reduced by the NaBH4 solution, the Seebeck coefficient and the PF value were further increased to -45.5 μV K-1 and 115.8 μW m-1 K-2, respectively. For demonstration, a maximum output voltage of 13.8 mV and output power of 492 nW were achieved using a three p-n junction-based TE device constructed by [Ag(NH3)2]+-PEI/SWCNT at a temperature difference of 50 K. Thus, this study provides a metal complex ion doping strategy to improve thermoelectrical properties and air stability of the PEI/SWCNT composite films, which have potential applications in flexible electronics.

Abstract
Single-walled carbon nanotube (SWCNT)-based thermoelectric materials have been extensively studied in the field of flexible wearable devices due to their high flexibility and excellent electrical conductivity (σ). However, poor Seebeck coefficient (S) and high thermal conductivity limit their thermoelectric application. In this work, free-standing MoS2/SWCNT composite films with improved thermoelectric performance were fabricated by doping SWCNTs with MoS2 nanosheets. The results demonstrated that the energy filtering effect at the MoS2/SWCNT interface increased the S of composites. In addition, the σ of composites was also improved due to the reason that S-π interaction between MoS2 and SWCNTs made good contact between MoS2 and SWCNTs and improved carrier transport. Finally, the obtained MoS2/SWCNT showed a maximum power factor of 131.9 ± 4.5 μW m-1 K-2 at room temperature with a σ of 680 ± 6.7 S cm-1 and an S of 44.0 ± 1.7 μV K-1 at a MoS2/SWCNT mass ratio of 15:100. As a demonstration, a thermoelectric device composed of three pairs of p-n junctions was prepared, which exhibited a maximum output power of 0.43 μW at a temperature gradient of 50 K. Therefore, this work offers a simple method of enhancing the thermoelectric properties of SWCNT-based materials.

Abstract
OBJECTIVE Heated and humidified high-flow nasal cannula (HFNC) therapy has been used to manage different respiratory conditions in pediatric patients. However, no review has summarized its efficacy for the management of pediatric obstructive sleep apnea (OSA). MATERIALS AND METHODS PubMed, Embase, CENTRAL, and Google Scholar were searched for all types of studies assessing the efficacy of HFNC for pediatric OSA. We compared pre-treatment and post-treatment obstructive apnea-hypopnea index (OAHI), obstructive hypopnea index (OHI), obstructive apnea index (OAI), SPO2 nadir and SPO2 mean values in a random-effect meta-analysis model. RESULTS Six studies reporting data of 67 pediatric patients treated with HFNC were included. Most of the data were from one-time titration. Meta-analysis revealed a statistically significant reduction in OAHI with HFNC therapy (MD: 15.58 95% CI: 8.30, 22.86 I2=77% p=0.001). Similarly, pooled analysis revealed that both OHI (MD: 12.35 95% CI: 0.78, 23.92 I2=98% p=0.04) and OAI (MD: 7.54 95% CI: 2.10, 12.98 I2=79% p=0.007) were significantly reduced with HFNC treatment. Also, HFNC led to statistically significant improvement in SPO2 nadir values (MD: -8.17 95% CI: -10.40, -5.94 I2=21% p<0.00001) but it did not change the mean SPO2 values before and after treatment (MD: -0.85 95% CI: -1.94, 0.25 I2=52% p=0.13). CONCLUSIONS Evidence from a limited number of heterogeneous and uncontrolled titration studies indicates that HFNC improves OAHI and minimum oxygen saturation in pediatric patients with OSA. However, further research is required on the long-term efficacy and compliance of HFNC therapy with a focus on different pediatric age groups.

Abstract
This study was designed to investigate the potential key genes of ADP-ribosylation factor-like 15 (ARL15) regulating glycolysis and lipogenesis in colon cancer. Hematoxylin-eosin (HE) staining and immunohistochemistry were used to observe the expression of ARL15 in 10 normal colon tissues and 10 colon cancer tissues. Immunofluorescence staining was used to observe the expression position of ARL15 in normal human colorectal mucosa cells (FHC) and colon cancer cells (HCT116 and SW620) with a confocal microscope. The ARL15 plasmid and small interfering RNA (siRNA) were constructed. After transfection, the expression levels of glycolysis and lipogenesis regulatory enzymes and messenger RNA (mRNA) transcription of ARL15 in over-expressed and silenced colon cancer cells were detected by Western blotting and real-time quantitative PCR (qRT-PCR). High expression of ARL15 in colon cancer tissue and low expression in normal colon tissue, and all expression are in the cytosol. The expression position of ARL15 in the FHC, HCT116, and SW620 cells was consistent and mainly distributed in the cytosol. After the pCMV-3Tag-2-ARL15 plasmid was transfected in HCT116, the protein expressions of FASN, AKT, P-AKT, P-GSK, SREBP-1 (p125) (p<0.01), and AMPK (p<0.001) were higher than those in the control group. The mRNA transcription level of FASN, GSK, AMPKa1, and SREBP-1 gene was higher than control group after the over-expression of ARL15. After the ARL15-siRNA was transfected in HCT116, the protein expression levels of PKM2, PFK, FASN, AKT, P-AKT, P-GSK, and AMPK decreased compared with the control group, (p<0.05). The mRNA transcription level of FASN, GSK, AMPKα1 gene was lower than control group after the low-expression of ARL15 (p<0.05). After adding 2 μM JIB-04, ARL15 in HCT116 showed statistical differences compared with the control group at 12 h, 24 h and 36 h (p<0.05). After adding 2 μM JIB-04, the protein expression levels of AKT, p-GSK, FASN, AMPK and SREBP-1 in HCT116 cells decreased significantly after 24 h. It was also found that the expression levels of AKT, P-GSK, FASN, AMPK and SREBP-1 genes in the dose-adding group were significantly lower than those in the control group. In summary, ARL15 may promote the occurrence of colon cancer by increasing the expression of protein kinase B/AMP-activated protein kinase (AKT/AMPK) downstream regulatory enzymes for glycogenesis and lipogenesis. JIB-04 can target ARL15 and affect its expression as well as the expressions of glucose and lipid metabolity-related proteins in AKT and AMPK signaling pathways.

Abstract
Abstract
Study question
what is the source, prevalence, and influence of microbial contamination on in vitro fertilization (IVF) and embryo transfer (ET) cycles?
Summary answer
Microbial contamination mainly occurs on Day 2, most caused by Escherichia coli carried with semen. ICSI could prevent contamination effectively and get good clinical outcomes.
What is known already
Microbial contamination occurs in IVF-ET system occasionally, which is hard to stop happening. The IVF culture system and laboratory environment, the patients’ follicular fluid and semen are not absolutely sterile, while the antibiotics in culture medium isn’t effective for all microbe types, and the artificial operations may bring in microbes. Generally, microbial contamination leads to degradation of embryos, reduction the number of embryos available, and infection of female reproductive tract, which would increase the cost of patients’ time, money, and bring psychological damages. A better understanding of embryo contamination in IVF culture system is of added value.
Study design, size, duration
A total of 29583 IVF-ET cycles were enrolled in this prospective observational study, from January 2010 to December 2020, included 70 microbial contamination cycles discovered in Day1-Day3 (D1-D3) of in vitro culture. Follicular fluid and semen saved on oocyte retrieval day, and culture medium contaminated were examined and identified for microorganisms at each contamination cycle.
Participants/materials, setting, methods
Compared the contamination rate of different insemination methods (IVF/ICSI/IVF+ICSI), different in vitro culture days (D1-D3), and different samples examination (follicular fluid, semen, culture medium) respectively, identified the source of microorganism types, compared the IVF culture outcomes and clinical outcomes between total contamination group (TC group, 42 cases) and partial contamination group (PC group, 28 cases).
Main results and the role of chance
A total of 70 microbial contamination cases occurred in 29583 oocyte retrieving cycles (0.24%), and it was observed only in IVF embryos but never in ICSI (Intracytoplasmic sperm injection) embryos. 38 contamination cases occurred on D2 with a highest ratio (54.3%) compared to D1 (32.9%) and D3(12.9%); Compared with follicular fluid, semen was the main cause inducing contamination from D1 to D3, and Escherichia coli in semen and culture medium, Enterococcus faecalis in follicular fluid proved to be the most common sources. Compared with TC group, the PC group showed a lower rate of No-available embryos (21.4% vs 81.0%) and a higher rate of blastocyst formation (41.2% vs 28.6%), In addition, the clinical pregnancy rate of PC group was higher than that of TC group in both fresh and frozen-thawed embryo transfer cycles (31.3% vs 16.7%, 38.5% vs 0.0%).
Limitations, reasons for caution
Further study is still necessary to better understand the sources that induce microbial contamination embryos, and more efficient methods are required to remove the microbes on these contaminated embryos so as better develop and manage a sterile micro-environment for successful embryo growth.
Wider implications of the findings: The differential embryonic microbe types associated to different IVF culture and clinical outcomes in patients undergoing IVF-ET might have profound implications for understanding the microbial sources and making a better management of IVF culture system.

Abstract
Background:Iguratimod (IGU) has demonstrated efficacy and safety for active rheumatoid arthritis (RA) patients in double-blind clinical trials in China and Japan as a new disease-modifying anti-rheumatic drug (DMARD). There are no studies evaluating the radiographic progression of structural joint damage of IGU for the treatment of RA using the mTSS as the primary endpoint.Objectives:Our study was to evaluate the efficacy and safety of IGU monotherapy and IGU combined methotrexate (MTX) compared with MTX monotherapy, including the inhibitory effects of joint destruction.Methods:This randomized, double-blind, parallel-controlled, multicenter study in patients with active RA who have not previously used MTX and biological DMARDs (bDMARDs) (ClinicalTrials.gov Identifier NCT01548001) was carried out in China. Patients were randomized 1:1:1 to receive IGU 25 mg twice a day (bid), MTX 10mg once a week(qw) for the first 4 weeks and 15 mg once a week(qw) for week 5 to 52, or IGU combined MTX (IGU+MTX) for 52 weeks. The primary endpoints were to assess and compare American College of Rheumatology 20% (ACR20) response and the change of modified total Sharp scoring (mTSS) score over 52 weeks (Intention-to-treat, ITT analysis). The non-inferiority test was used to analyze the difference of ACR20 response at 52 weeks between the IGU monotherapy and the MTX monotherapy arms, and the non-inferiority limit value was 10%. The difference test was used for the comparison between the IGU+MTX and MTX monotherapy arms. Two-way ANOVA was used to analyze the difference of the changes of mTSS score of each arm compared with baseline value (0 week).Results:A total of 895 patients were randomized to IGU 25mg bid (n =297), MTX 10-15mg qw(n=293), and IGU+MTX (n=305).

As shown in fig 1, the structural remission (ΔmTSS≤0.5) was statistically significant for IGU monotherapy (57.4%, P=0.0308) but not for IGU+MTX arm (55%) versus MTX monotherapy (47.8%).Overall incidence of the adverse events (AEs) leading to study discontinuation were reported in 13.8% (41/297) in IGU monotherapy arm, 11.26% (33/293) in MTX monotherapy arm and 11.51% (35/305) patients in IGU+MTX arm. The incidence of adverse drug reactions (ADR) leading to study discontinuation were 11.45% (34/297), 8.53% (25/293) and 9.21% (28/305), respectively. There was no one death and no significant difference in all the safety indicators among the three arms.Conclusion:Iguratimod alone or in combination with MTX demonstrated superior efficacy with acceptable safety compared to MTX for patients with active RA who have not previously used MTX bDMARDs.Disclosure of Interests:None declared

Abstract
Here, we put forward an effective strategy to regulate the interface structure of carbon nanotubes/polyaniline (CNTs/PANI) composite films and improve their thermoelectric (TE) properties by sequential dedoping-redoping treatment. Dedoping induces conductive resistance-undoped PANI to enhance the energy barrier between CNTs and PANI, leading to a greatly increased Seebeck coefficient and deteriorated conductivity. Subsequently, upon the redoping process, the electrical conductivity is dramatically improved owing to the generated conductive PANI chains, while Seebeck coefficient is maintained at 90% of the dedoped composites. This yields a significantly improved power factor of 407 μW m-1 K-2 from the as-prepared composites (234 μW m-1 K-2), which is the highest value among those of all the reported CNTs/PANI composites. The outstanding TE performanceis probably ascribed to the multiple interface structure of the PANI composite generated from incomplete dedoping and redoping processes, contributing to the enhanced carrier-filtering effect to retain a relatively high Seebeck coefficient and efficient charge transport to improve conductivity. Furthermore, the flexible TE device generates a high power of 1.5 μW at ΔT = 50 K, demonstrating the applicability of this composite for energy-harvesting electronic devices.

Abstract
FibroTouch (FT) has been used widely in clinic. Studies of the FT diagnostic efficiency and influencing factors of liver stiffness measurement (LSM) of liver fibrosis in autoimmune liver diseases (AILD) have shown that FT has a good diagnostic efficiency and accuracy, especially in AIH. However, for patients with primary biliary cholangitis and overlap syndrome of autoimmune hepatitis, FT results should be vigilant. In addition, the diagnostic efficiency of FT. Notably, when using FT to diagnose AILD, the value of elastic stiffness depends on five influencing factors, such as, age, total bile acid, international standardized ratio, FIB-4 index, and prothrombin time.

Abstract
Objective: To investigate the protective effect of carbon monoxide releasing molecule 2 (CORM-2) on post-resuscitation myocardial dysfunction in rats. Methods: Forty male SD rats which were healthy were randomly divided into 5 groups: sham operated group(sham group), cardiopulmonary resuscitation(PCR) group, DMSO group, inactivated CORM-2(iCORM-2) group and CORM-2 group (n=8 each). Established the model of post-cardiac arrest myocardial dysfunction by intravenous potassium chloride (4 ℃) injection combined with asphyxiation for 4 minutes and then followed by artificial chest compression for 3 minutes. Sham group: rats were instrumented with catheter without inducing cardiac arrest and resuscitation, and intraperitoneal injection of 0.9% normal saline (4 ml/kg) was performed 12 hours before catheterization. CPR group: rats were instrumented with catheters and underwent CPR, and intraperitoneal injection of 0.9% normal saline (4 ml/kg) was performed 12 hours before surgery.CORM-2 group: rats were instrumented with catheters and underwent CPR, intraperitoneally injected the prepared CORM-2 solution (4 mg/kg) at 12 hours before surgery. DMSO group: rats were instrumented with catheters and underwent CPR, intraperitoneally injected the prepared DMSO solution (4 ml/kg) at 12 hours before surgery. iCORM-2 group: rats were instrumented with catheters and underwent CPR, iCORM-2 solution (4 mg/kg) was intraperitoneally injected at 12 hours before surgery. Hemodynamic data (MAP, +dp/dtmax, -dp/dt) were continuously monitored and recorded for 4 hours after resuscitation (or catheterization) in each group. Myocardial tissue specimen and blood samples were taken after resuscitation (or catheterization). The myocardial ultrastructure was observed by transmission electron microscope. Lactate dehydrogenase (LDH) activity was measured by lactate-pyruvate method. Serum creatine kinase isoenzyme (CK-MB) concentration was measured by ELISA. Western blot was used to detect the levels of Caspase-3, Caspase-9 and Cyt-C protein in myocardial tissue. Results: MAP, +dp/dtmax and -dp/dt at 0.5, 1, 2, 3 and 4 hours post resuscitation were significantly lower than those immediately after catheterization in CRP, DMSO, iCORM-2 groups (all P<0.05). MAP at 0.5, 1, 2, 3, and 4 hours post resuscitation were significantly lower in CRP, DMSO and iCORM-2 groups than those at respective time points in sham group (all P<0.05), while MAP was similar between CORM-2 group and Sham group at these time points (all P>0.05). +dp/dtmax and -dp/dt values at 0.5, 1, 2, 3, and 4 hours post resuscitation were lower than those at respective time points in sham group and significance was found at 0.5, 1 and 2 hours post resuscitation (both P<0.05), while +dp/dtmax and -dp/dt values were similar between CORM-2 group and sham group at various time points (all P>0.05). Myocardial ultrastructure, especially mitochondrial structural integrity was better preserved in the CORM-2 group than those in the other resuscitation groups at 4 hours after resuscitation. Serum LDH activity and CK-MB concentration were significantly elevated at 4 hours after resuscitation in the CPR group, DMSO group and iCORM-2 group than those in sham group (all P<0.01); CK-MB concentration was also higher in CORM-2 group than that in sham group,and LDH level was similar between CORM-2 group and sham group (P>0.05). Serum LDH activity and CK-MB concentrations were significantly lower in the CORM-2 group than those in the other resuscitation groups (all P<0.01). The myocardial expressions of Caspase-3, Caspase-9 and Cyt-C at 4 hours after resuscitation were significantly higher in the CPR group, DMSO group and iCORM-2 group than those in sham group; the myocardial expressions of Caspase-3 and Caspase-9 were significantly higher in CORM-2 group than those in sham group (both P<0.05), while Cyt-C expression was similar between CORM-2 group and sham group. The expressions of the above 3 proteins were significantly lower in the CORM-2 group than those in the other resuscitation groups (all P<0.05). Conclusions: CORM-2 can effectively alleviate post-resuscitation myocardial injury in rats with cardiopulmonary resuscitation and improve cardiac function. Protecting myocardial mitochondria and inhibiting mitochondrial apoptosis pathway may serve as the protective mechanisms in this model.

Abstract
Abstract
To analyze the correlation of the level of serum heat shock protein 90α (HSP-90α) in healthy and breast cancer patients, studying the evaluation of neoadjuvant efficacy and Clinical value of relapse monitoring.
A total of 102 healthy women were selected, 51 cases of breast benign tumor ,423 cases of female breast cancer all diagnosed by pathology,other system malignancies 62 cases. ALL the serum samples HSP-90αwas detected by double-antibody ELISA. The CEA, CA125,CA15-3 were detected by Roche Cobas ECL analyzer. The ROC curve was used to analyze the effectiveness of serum HSP-90α in the early diagnosis of breast cancer. The dynamic changes of HSP-90αlevel before and after treatment were analyzed by Wilcoxon's rank test. Moreover, we also combine the HSP-90αwith CEA,CA125,CA15-3 to evaluate the clinical value of monitoring the recurrence of breast cancer.
The levels of serum HSP-90α (123.49 ± 105.1ng / ml) in breast cancer patients wes significantly higher than that in healthy controls (40.33 ± 14.18ng / ml), benign breast disease (80.15 ± 103.09ng / ml) and carcinoma in situ (34.7 ± (114.31 ± 146.91ng / ml),the difference was statistically significant (P <0.001). .According to the ROC curve analysis of patients and healthy subjects, the cut-offvalue was set as HSP-90=59.7ng / ml, AUC=0.834, the sensitivity and specificity to diagnosis of breast cancer was 90.3% and 78.6% respectively ,the negative predictive value was 93.88%.The levels of serum HSP-90α was significantly decreased (P <0.05) after tumor resection and the patients who obtain PR from the neoadjuvant chemotherapy. When HSP-90=43.22ng / ml was set as the cut-off value for diagnosing the recurrence of breast cancer, AUC=0.877,the sensitivity and specificity were 95.7% and 74.5% respectively, and the negative predictive value was 96.2%. At the same time, we find that combined HSP-90α with CEA, CA125, CA15-3 can improve the accuracy of recurrence prediction.
Serum HSP-90α has a good clinical diagnostic value in breast cancer and can be used as a recurrence monitoring tool for post-adjuvant treatment patients.

Abstract
BACKGROUND In the West, the safety and efficacy of the Lotus valve have been demonstrated; however, data in the Chinese population are still lacking. Few studies have compared the clinical outcomes of transcatheter aortic valve replacement (TAVR) with the Lotus valve in patients with bicuspid or tricuspid aortic valve stenosis. Our aim was to assess TAVR outcomes with the Lotus aortic valve in a Chinese patient cohort. METHODS In total, 23 symptomatic, high-surgical risk patients with severe aortic valve stenosis were enrolled. Among them, nine patients (39%) had bicuspid aortic valves, and three patients had a large annulus dimension. The Lotus valve was successfully implanted in all patients. To facilitate accurate positioning, partial re-sheathing was attempted in ten patients (43.5%), while one patient had a full retrieval. One-year clinical follow-up was completed in all patients. RESULTS There were no deaths, strokes, or major adverse cardiac and cerebrovascular events in 22 of the 23 patients at 30 days; the all-cause mortality rate at 1 year was 4.4% (1 of 23 patients). The mean aortic valve gradient decreased from 51.5 ± 8.8 mm Hg at baseline to 13.4 ± 4.9 mm Hg (p < 0.001) and the valve area increased from 0.6 ± 0.2 cm2 to 1.5 ± 0.4 cm2 (p < 0.001) at 30 days. Paravalvular leakage was absent or mild (22%), and no patient had severe paravalvular leakage. Six patients (26.1%) required a postprocedural pacemaker. There was no difference regarding the procedural and the 1‑year outcomes between patients with bicuspid and tricuspid aortic valve stenosis. CONCLUSION Our single-center experience demonstrated that the Lotus valve is feasible and effective for Chinese patients with aortic valve stenosis, including atypical cases with bicuspid aortic valves or large aortic annulus size.

Abstract
Magnetic particle imaging is an emerging tomographic technique with the potential for simultaneous high-resolution, high-sensitivity, and real-time imaging. Magnetic particle imaging is based on the unique behavior of superparamagnetic iron oxide nanoparticles modeled by the Langevin theory, with the ability to track and quantify nanoparticle concentrations without tissue background noise. It is a promising new imaging technique for multiple applications, including vascular and perfusion imaging, oncology imaging, cell tracking, inflammation imaging, and trauma imaging. In particular, many neuroimaging applications may be enabled and enhanced with magnetic particle imaging. In this review, we will provide an overview of magnetic particle imaging principles and implementation, current applications, promising neuroimaging applications, and practical considerations.

Abstract
Objectives The aim of this study is to investigate the sex-specific aortic root anatomy in patients with bicuspid aortic valve (BAV). Patients and methods This retrospective study includes 73 consecutive patients with BAV who underwent CT evaluation before transcatheter aortic valve replacement (TAVR) between July 2013 and April 2017 in the Second Affiliated Hospital of Zhejiang University. Result The size of the annulus, diameter and height of the sinotubular junction (STJ), height of the coronary artery ostia, and dimension of the aorta were measured. Women had significantly smaller annulus parameters (mean diameter: 23.4 ± 1.8 vs. 26.1 ± 2.1 mm; area: 425.3 ± 59.4 vs. 527.4 ± 84.6 mm2; perimeter: 74.3 ± 5.2 vs. 83.2 ± 6.4 mm), and STJ diameter (29.7 ± 3.1 vs. 32.6 ± 4.5 mm) than men (p < 0.01 for all), even after adjustment for their smaller body surface area (BSA). Dimension of aorta and height of right coronary artery were also significantly smaller in women, although not when indexing for the BSA. The left ventricular ejection fraction of women is significantly higher than that of men before discharge (60.2 ± 9.7% vs. 53.7 ± 13.6%, p = 0.01). There were no differences between women and men in the all-cause 30-day and 1‑year mortality. Conclusion Women with BAV had smaller annulus and STJ diameter after indexing for BSA, reflecting a sex-specific difference. There were no differences in 30-day and 1‑year mortality between the two groups.

Abstract
Objective: To investigate the influential factors of efficacy of the first (131)I ablation therapy for thyroid remnant in papillary thyroid microcarcinoma (PTMC) patients after thyroidectomy. Methods: Eighty-nine PTMC patients who underwent twice (131)I ablation therapy and (131)I whole body follow-up scan ((131)I-WBS) within 5 to 8 months in our department from September 2007 to October 2016 were identified and enrolled in present study. Patients were divided into complete-ablation group and uncomplete-ablation group according to whether or not radioactivity was detected at the thyroid bed in (131)I-WBS. The χ(2) test and multi-variance Binary logistic regression were performed for the factors which might affect the therapeutic efficacy. Results: The first (131)I ablation therapy was successful in 41 of 89 patients (46.07%). Residual thyroid weight was found to be associated with therapeutic efficacy (P<0.05), while gender, age, surgical method, lesions'maximum diameter, with or without LN metastasis, with or without distant metastasis, time of operation from first (131)I treatment, lesions'number, thyroid stimulating hormone (TSH), thyroglobulin (Tg), the consistency of (131)I-WBS and (99)Tc(m)-pertechnatate, TNM stage, ATA risk, Tg/TSH ratio were not significant associated with therapeutic efficacy. Binary logistic regression analysis was performed in these respects and it indicated that residual thyroid weight and ATA risk were not statistically significant independent variable (P>0.05). Conclusions: Residual thyroid weight might affect efficacy of the first (131)I ablation therapy on thyroid remnant in PTMC patients after thyroidectomy, but it is not an independent factor. Multiple interrelated factors should be considered when predicting the efficacy of the first (131)I ablation therapy.

Abstract
We have investigated the relationship between plasma Na-K ATPase inhibitor activity (EDLS) and intracellular ions in 37 uremic hemodialysed hypertensive patients, and in 20 normotensive non uremic controls (NC). As compared with the NC population, significantly enhanced values for erythrocyte (RBC) Na, Ca, platelet cytosolic Ca and EDLS were observed in all the uremic patients tested just before a dialysis session, as well as a decrease in RBC Ca ATPase and in the platelet pH. In uremia, significant correlations have been noted between RBC Na and platelet Ca (r = 0.6) or systolic BP (r = 0.45); between platelet Ca and systolic blood pressure (r = 0.8) or diastolic BP (r = 0.5) and between EDLS and RBC Na, Ca or platelet Ca (r = 0.5). Anti-hypertensive treatment has no influence on these parameters. During dialysis, a significant decrease has been noted in RBC Na, Ca, platelet Ca, SBP (only in untreated patients) and EDLS and an increase in RBC Ca ATPase and platelet pH. These modifications are significantly correlated with the weight change.

Abstract
Objective: To evaluate the feasibility, safety, and preliminary efficacy of percutaneous transcystic papilla balloon dilation for the common bile duct stones. Methods: A total of 11 patients with the common bile duct stones without dilatation of the intrahepatic bile ducts treated with percutaneous transcystic papilla balloon dilation in multiple center from April 2013 to May 2015 were analyzed retrospectively.In these 11 patients, there were 3 males and 8 females.And the average age was 68(52-91) years old.All patients had no obviously dilated intrahepatic bile duct, 6 patients were not suitable for endoscopic treatment or surgery, 4 patients refused endoscopic or surgical treatment and 1 patient had a history of failed endoscopic treatment.The white blood cell count, CA19-9, total bilirubin, direct bilirubin, AST, ALT and serum amylase level were recorded before the procedure, 1 week, and 1 month later.Early complications, such as cholangitis, pancreatitis, hemorrhage, and perforation were evaluated. Results: Technical success was achieved in all the 11 cases.The level of CA19-9, total bilirubin and direct bilirubin decreased significantly 1 week and 1 month after the procedure.One patient suffered from biliary tract infection.No severe complications, such as perforation of biliary or gastrointestinal tract, occurred during the follow up.Common bile duct stone recurred in 1 patient 2 years after the procedure. Conclusions: For cases who are not suitable for endoscopic treatment, surgery, or percutaneous transhepatic approach to treat the common bile duct stones, percutaneous transcystic papilla dilation is technically feasible and safe, and seems to be an appropriate alternative strategy.

Abstract
OBJECTIVE To determine the prevalence of latent tuberculosis infection (LTBI) in college students. PATIENTS AND METHODS Four hundred and twenty newly admitted college students were enrolled. The Enzyme-Linked ImmunoSpot assay (ELISPOT) was used. Overall, 171 students with ELISPOT assay+/TST+ were monitored for three years to detect active TB disease. RESULTS The overall positive rate of ELISPOT assay was 40.7% among TST+ students. The ELISPOT positive rates were 36.9%, 45.4%, and 64.3% in groups of TST induration of 10-14mm, 15-20mm, and ≥20mm, respectively, with a significant difference (χ(2)=10.136, P<0.01) but no significant difference between BCG scar and no scar (41.2% vs. 38.8%; P>0.05). None of the 171 untreated students contracted active TB within the three-year monitoring period. CONCLUSION The LTBI rate might be overestimated by TST compared with interferon-γ release assays. On the basis of a close monitoring, few students developed active TB despite a positive result to the TST and ELISPOT assay.

Abstract
Abstract
Background: SPARC (secreted protein acidic and rich in cystein) is a secreted glycoprotein that interacts with extracellular matrix protein and acts as a regulator of critical cellular functions such as proliferation and cell migration. An increasing number of studies have shown altered expression of SPARC in several malignancies. However, the role of this potential biomarker in breast cancer development and progression is controversial. Triple-negative breast cancer (TNBC) is known for its poor prognosis and high recurrence probability. There is a need for prognostic biomarkers to guide treatment decisions for this subtype.
Objective: To explore the association between SPARC and the prognosis of triple-negative breast cancer.
Methods: In this study, a total of 211 samples of triple-negative breast lesions from 2004 to 2008 were collected in Cancer Hospital, Chinese Academy of Medical Sciences. SPARC expression was evaluated by immunohistochemistry using an immunoreactive score (IRS) from patients with up to 10 years clinical follow-up data. The current study set out to examine both the expression of SPARC in primary tumor tissue and to demonstrate if a link existed between the levels of SPARC and the clinical outcome. Cox proportional hazards model was used to estimate HRs and 95%CI, stratified on tumor grade, TNM stage, lymph node status and vascular invasion.
Results: High SPARC expression (IRS≥3) was observed in 52.1% of all primary tumors. Patients expressing low levels of SPARC had better disease-free survival (DFS) (HR=0.632, 95%CI:0.405-0.987, P = 0.044) as well as overall survival(OS)(HR=0.576, 95%CI:0.351-0.946, P = 0.029) compared to those with high SPARC expression levels.Furthermore, the presence of high SPARC expression was an independent prognostic factor for both DFS (HR=1.67, 95%CI:1.04-2.69, P=0.034) and OS(HR=1.77, 95%CI:1.04-3.01, P=0.037) of triple-negative breast cancer patients, stratified on tumor grade, TNM stage, lymph node metastasis and vascular invasion, with adjustment for age, hormonal status, tumor size, adjuvant radiotherapy and adjuvant chemotherapy.
Conclusion: Our results suggest that the presence of higher SPARC expression could be an indicator of high aggressiveness and may be a strong prognostic factor for triple-negative breast cancer.

Abstract
Currently drug resistance has remained a major challenge in successful breast cancer therapy. Wogonin, one of the active components of scutellaria baicalensis, has shown anticarcinogenic, chemopreventive, and immunoregulatory functions. The present study aimed to explore whether wogonin exerted synergistic cytotoxicity with doxorubicin in breast cancer. Our data indicated that wogonin inhibited the proliferation of breast cancer cells in a dose- and time-dependent manner. Combined treatment with wogonin increased the doxorubicin sensitivity in breast cancer cells. Moreover, administration with wogonin alone or in combination with doxorubicin suppressed the expression of insulin like growth factor 1 receptor (IGF-1R) in Bcap-37 and MCF-7 cells. Incubation with insulin like growth factor (IGF) I or IGF-II promoted cell growth, which was reversed by wogonin co-administration. Mechanically, we found that down-regulation of IGF-1R diminished the chemosensitization role of wogonin in breast cancer. In addition, wogonin suppressed the phosphorylation levels of AKT and addition of AKT inhibitor abolished the synergistic cytotoxicity of wogonin and doxorubicin. Taken together, combined treatment with wogonin increased the doxorubicin sensitivity in breast cancer cells through regulation of IGF-1R/AKT signaling pathway. Therefore, these findings demonstrated that combination therapy with wogonin led to better therapeutic effects via regulating IGF-1R/AKT signaling pathway in doxorubicin-based chemotherapy for breast cancer.

Abstract
Human age-related retinal diseases, such as age-related macular degeneration (AMD), are intimately associated with decreased tissue oxygenation and hypoxia. Different antioxidants have been investigated to reverse AMD. In the present study, we describe the antioxidant 17β-estradiol (βE2) and investigate its protective effects on retinal neurons. Fourteen days after ovariectomy, adult Sprague-Dawley rats were exposed to 8000-lux light for 12h to induce retinal degeneration. Reactive oxygen species (ROS) levels were assessed by confocal fluorescence microscopy using 2,7-dichlorofluorescein diacetate. Nuclear factor erythroid 2-related factor 2 (Nrf2) and antioxidant enzyme mRNA expression were detected by real-time PCR. Western blotting was used to evaluate NRF2 activation. NRF2 translocation was determined by immunohistochemistry, with morphological changes monitored by hematoxylin and eosin staining. Following light exposure, βE2 significantly reduced ROS production. βE2 also up-regulated NRF2 mRNA and protein levels, with maximal expression at 4 and 12h post-exposure, respectively. Interestingly, following βE2 administration, NRF2 was translocated from the cytoplasm to the nucleus, primarily in the outer nuclear layer. βE2 also up-regulated NRF2, which triggered phase-2 antioxidant enzyme expression (superoxide dismutases 1 and 2, catalase, glutaredoxins 1 and 2, and thioredoxins 1 and 2), reduced ROS production, and ameliorated retinal damage. However, the beneficial effects of βE2 were markedly suppressed by pretreatment with LY294002 or ICI182780, specific inhibitors of the phosphatidylinositol 3-kinase-Akt (PI3K/AKT), and estrogen receptor (ER) signaling pathways, respectively. Taken together, these observations suggest that βE2 exerts antioxidative effects following light-induced retinal degeneration potentially via NRF2 activation. This protective mechanism may depend on two pathways: a rapid, non-genomic-type PI3K/AKT response, and a genomic-type ER-dependent response. Our data provide evidence that βE2 is a potentially effective in the treatment of retinal degeneration diseases.

Abstract
Four cycles of chemotherapy are required to assess responses of multiple myeloma (MM)
patients. We investigated whether circulating endothelial progenitor cells (cEPCs)
could be a biomarker for predicting patient response in the first cycle of
chemotherapy with bortezomib and dexamethasone, so patients might avoid ineffective
and costly treatments and reduce exposure to unwanted side effects. We measured cEPCs
and stromal cell-derived factor-1α (SDF-1α) in 46 MM patients in the first cycle of
treatment with bortezomib and dexamethasone, and investigated clinical relevance
based on patient response after four 21-day cycles. The mononuclear cell fraction was
analyzed for cEPC by FACS analysis, and SDF-1α was analyzed by ELISA. The study
population was divided into 3 groups according to the response to chemotherapy: good
responders (n=16), common responders (n=12), and non-responders (n=18). There were no
significant differences among these groups at baseline day 1 (P>0.05). cEPC levels
decreased slightly at day 21 (8.2±3.3 cEPCs/μL) vs day 1 (8.4±2.9
cEPCs/μL) in good responders (P>0.05). In contrast, cEPC levels increased
significantly in the other two groups (P<0.05). SDF-1α changes were closely
related to changes in cEPCs. These findings indicate that change in cEPCs at day 21
in the first cycle might be considered a noninvasive biomarker for predicting a later
response, and extent of change could help decide whether to continue this costly
chemotherapy. cEPCs and the SDF-1α/CXCR4 axis are potential therapeutic targets for
improved response and outcomes in MM patients.

Abstract
We report the case of a father and son diagnosed with atypical chronic myeloid leukemia (aCML). Both patients harbored SETBP1 mutations, which are present in 24.3% of aCML patients. Moreover, both shared the variant encoding p.Pro737His, but the aCML severity was greater in the son because of the presence of two other missense mutations causing p.Asp868Asn and p.Ser885Arg alterations. SETBP1 mutations may be associated with an adverse prognosis, so their detection would help in the diagnosis of aCML and the determination of a patient's prognosis.

Abstract
PTEN serves as an intrinsic brake on neurite outgrowth, but the regulatory mechanism that governs its action is not clear. In the present study, miR-29a was found to increase neurite outgrowth by decreasing PTEN expression. Results showed that miR-92a-1, miR-29a, miR-92b, and miR-29c expression levels increased during nerve growth factor (NGF)-induced differentiation of PC12 cells. Based on in silico analysis of possible miR-29a targets, PTEN mRNA may be a binding site for miR-29a. A protein expression assay and luciferase reporter assay showed that miR-29a could directly target the 3'-UTRs (untranslated regions) of PTEN mRNA and down-regulate the expression of PTEN. PC12 cells infected with lentiviral pLKO-miR-29a showed far higher levels of miR-29a and Akt phosphorylation level than those infected with control. This promoted neurite outgrowth of PC12 cells. Collectively, these results indicate that miR-29a is an important regulator of neurite outgrowth via targeting PTEN and that it may be a promising therapeutic target for neural disease.

Abstract
The Japanese Black cattle (Wagyu) plays a significant part in the Japanese beef industry because it is numerically the largest breed group and comprises ~93% of the national purebred beef cow herd. Japanese Black cattle are genetically predisposed to intense marbling and to a high percentage of unsaturated fat resulting in a meat characterised by both high quality and price on the market. Like other breeds, genetic improvement and production traits in Wagyu can be fostered by the implementation of traditional reproductive strategies such as multiple-ovulation embryo transfer. A multiple-ovulation embryo transfer case study was performed in a leading production centre in Hainan island, South China. Donors (n = 40) were split into 2 groups receiving either a total dose of 400 mg of FSH Folltropin (FSH USA; Folltropin Bioniche Inc., USA; n = 24), or 10 mg of an FSH formulation produced from the Institute of Zoology of the Chinese Academy of Sciences (FSH CHN; n = 16). In both cases, dosages were equally distributed over a 4-day administration schedule. Both donors and recipients (198 heifers) were synchronized for fixed-time embryo transfer (ET) and AI, respectively, by adopting the Ovsynch protocol. Such protocol consists of GnRH administration at Day 0, followed by prostaglandin administration at Day 7 and a second administration of GnRH at Day 9. Artificial insemination was performed on donor animals at 12 and 24 h from the last GnRH administration, whereas for recipient synchronization receiving fresh embryos, the second GnRH administration was given at the time of second AI on donors, and ET was performed 7 days following the first AI. Final synchronization at the time of ET, judged by the ultrasonic presence of a functional corpus luteum, was 53% (105/198). The following parameters for FSH USA and FSH CHN were found to be not significantly different (Student's t; mean ± s.e.): i) ovulations (10.5 ± 1.2 v. 8.5 ± 1.2; P = 0.2); ii) embryos (6.3 ± 1.2 v. 5.1 ± 1.1; P = 0.5), and iii) embryos from ovulated donors (6.8 ± 1.3 v. 5.8 ± 1.1; P = 0.6). Recovered embryos from the 2 groups were also not different: i) degenerated embryos (1.0 ± 0.4 v. 0.8 ± 0.2; P = 0.6); ii) morula (4.0 ± 0.8 v. 2.6 ± 0.5; P = 0.1), and iii) early blastocysts (4.0 ± 1.2 v. 3.3 ± 0.5; P = 0.6). Blastocysts were recovered only from donors treated with FSH USA. Out of 233 recovered embryos, 34 were transferred as fresh and 71 as frozen/thawed. Pregnancy rate at 60 days following ET for fresh and frozen/thawed embryos was 47.1 and 35.2%, respectively (P = 0.2). Within frozen embryos, pregnancy rates derived from transferred morulas and blastocysts were 25 and 45.5% (P = 0.07). When considering the two sources of hormones, overall pregnancy rates were similar between the two groups (28/71, 39.4% v. 13/34, 38.2%; P = 0.9). Finally, pregnancy rates from the transfer of fresh embryos (9/21, 42.8% v. 7/13, 53.8%; P = 0.6) and frozen/thawed embryos (19/50, 38% v. 6/21, 23.8%; P = 0.6) were also not different. In conclusion, all parameters in this study did not differ between the 2 sources of FSH; however, a lower incidence of degenerated embryos and a higher pregnancy rate following transfer of frozen/thawed embryos occurred when FSH USA was used in donor animals.

Abstract
The influence of lattice-melt-induced resistivity gradients on the transport of mega-ampere currents of fast electrons in solids is investigated numerically and experimentally using laser-accelerated protons to induce isochoric heating. Tailoring the heating profile enables the resistive magnetic fields which strongly influence the current propagation to be manipulated. This tunable laser-driven process enables important fast electron beam properties, including the beam divergence, profile, and symmetry to be actively tailored, and without recourse to complex target manufacture.

Abstract
To evaluate the diagnostic values of using autoantibodies in sera to a panel of eight tumor-associated antigens (TAAs) of P53, Koc, P62, C-myc, IMP1, Survivn, P16 and Cyclin B1 full-length recombinant proteins for early detection of patients with gastric cardia adenocarcinoma (GCA) and high-risk subjects screening. Enzyme-linked immunosorbent assay was used to detect autoantibodies against the eight selected TAAs in 383 sera samples from four groups, including 140 subjects with normal gastric cardia epithelia (NOR), 76 patients with chronic atrophic gastritis (CAG), 79 patients with gastric cardia dysplasia (DYS) and 88 patients with GCA. In addition, the expression of the eight antigens was analyzed in gastric cardia tissues by immunohistochemical method. The individual autoantibodies to six TAAs (P53, P62, IMP1, Survivn P16 and Cyclin B1) were significantly higher in sera from patients with GCA than that in normal subjects (P < 0.05). When autoantibody assay successively accumulated to seven TAAs (P53, Koc, P62, C-myc, IMP1, Survivn and P16), a stepwise increased detection frequency of autoantibodies was found in the four sera groups (13% in NOR, 39% in CAG, 46% in DYS, and 64% in GCA, respectively), the risks to CAG, DYS and GCA steadily increased about 4.4-, 5.7- and 12.0-fold. The sensitivity and the specificity for autoantibodies against the seven TAAs in diagnosing GCA reached up to 64% and 87%, respectively. The area under the receiver operating characteristic curve for the seven anti-TAA autoantibodies was 0.73 (95%CI: 0.68-0.78) No more increase in sensitivity was found with the addition of new anti-TAA autoantibodies. A combination detection of autoantibodies to TAAs might be helpful to distinguish GCA patients from normal subjects and the patients with gastric cardia precancerous lesions. In addition, further studies in patients with GCA and precancerous lesions using enlarged TAA panels might improve the sensitivity and specificity of cancer detection and high-risk subjects screening.
