Abstract
Traffic light detection is crucial for environment perception and decision-making in autonomous driving. State-of-the-art detectors are built upon deep Convolutional Neural Networks (CNNs) and have exhibited promising performance. However, one looming concern with CNN based detectors is how to thoroughly evaluate the performance of accuracy and robustness before they can be deployed to autonomous vehicles. In this work, we propose a visual analytics system, VATLD, equipped with a disentangled representation learning and semantic adversarial learning, to assess, understand, and improve the accuracy and robustness of traffic light detectors in autonomous driving applications. The disentangled representation learning extracts data semantics to augment human cognition with human-friendly visual summarization, and the semantic adversarial learning efficiently exposes interpretable robustness risks and enables minimal human interaction for actionable insights. We also demonstrate the effectiveness of various performance improvement strategies derived from actionable insights with our visual analytics system, VATLD, and illustrate some practical implications for safety-critical applications in autonomous driving.

Abstract
Objective: To evaluate the diagnostic performance of quantitative fecal immunochemical testing (FIT) and to provide reference for designing effective colorectal cancer (CRC) screening strategy in China. Methods: Based on an ongoing randomized controlled trial comparing the colorectal cancer screening strategies, this current study involved 3 407 participants aged 50-74 years who had undergone colonoscopies. All the feces samples were collected from the participants prior to receiving the colonoscopy. Fecal hemoglobin (Hb) was tested by FIT following a standardized operation process. Diagnosis-related indicators of FIT were calculated using the colonoscopy results as the gold standard. Results: Among the 3 407 participants, the mean age (SD) as 60.5 (6.3) years and 1 753 (51.5%) were males. The participants involved 28 (0.8%) CRCs, 255 (7.5%) advanced adenomas, 677 (19.9%) nonadvanced adenomas, and 2 447 (71.8%) benign or negative findings. With an overall positivity rate of 2.8% (96/3 407) at the recommended cutoff value of 20 μg Hb/g, the sensitivities of FIT for both CRC and advanced adenoma were 57.1% (95%CI: 37.2%-75.5%) and 11.0% (95%CI: 7.4%-15.5%), respectively, with the corresponding specificity as 98.4% (95%CI: 97.8%-98.8%). At a decreased cut-off value of 5 μg Hb/g, the sensitivities for detecting CRC and advanced adenoma increased to 64.3% (95%CI: 44.1%-81.4%) and 16.5% (95%CI: 12.1%-21.6%), respectively, but the specificity reduced to 95.2% (95%CI: 94.4%-95.9%). The areas under the ROC curve for CRC and advanced adenoma were 0.908 (95%CI: 0.842-0.973) and 0.657 (95%CI: 0.621-0.692), respectively. Of the diagnostic performance, there were no significant differences noticed by different sex and age groups. Conclusions: In our study, the quantitative FIT showed modest sensitivity in detecting CRC but limited sensitivity in detecting advanced adenoma. In population-based CRC screening programs, the quantitative FIT had the advantage of adjusting the positive threshold based on the targeted detection rate and available resource load of colonoscopy.

Abstract
Objective: To compare the rates of acceptance of colonoscopy, fecal immunochemical test (FIT), or a novel risk-adapted screening approach in the colorectal cancer (CRC) screening program. Related risk factors were also studied. Methods: The study has been based on an ongoing randomized controlled trial on colorectal cancer screening programs in six centers of research since May 2018. The involved participants were those who presented at the baseline screening phase. All the participants were randomly allocated into one of the following three intervention arms in a 1∶2∶2 ratio: colonoscopy group, FIT group, and a novel risk-adapted screening group. All the participants underwent risk assessment on CRC by an established risk score system. The subjects with high-risk were recommended to undertake the colonoscopy while the low-risk ones were receiving the FIT. Detailed epidemiological data was collected through questionnaires and clinical examinations. Rates of participation and compliance in all three groups were calculated. Multivariate logistic regression models were used to explore the potential associated factors related to the acceptance of screening. Results: There were 19 546 eligible participants involved in the study, including 3 916 in the colonoscopy group, 7 854 in the FIT group, and 7 776 in the novel risk-adapted screening group, respectively. Among the 19 546 participants, the mean age was 60.5 years (SD=6.5), and 8 154 (41.7%) were males. The rates of participation in the colonoscopy, FIT and the novel risk-adapted screening groups were 42.5%, 94.0% and 85.2%, respectively. In the novel risk-adapted screening group, the participation rate was 49.2% for the high-risk participants who need to undertake colonoscopy and was 94.0% for the low-risk ones who need to undertake FIT. Results from the multivariate logistic regression models demonstrated that there were several factors associated with the rates of participation in CRC screening, including age, background of education, history of smoking cigarettes, previous history of bowel examination, chronic inflammatory bowel disease and family history of CRC among the 1(st)-degree relatives. Conclusions: FIT and the novel risk-adapted screening approach showed superior participation rates to the colonoscopy. Further efforts including health promotion campaign for specific target population are needed to improve the engagement which ensures the effectiveness of CRC screening programs.

Abstract
Jiangsu Province was once one of the provinces that are hyperendemic for schistosomiasis in China. Following the concerted efforts for nearly 70 years, the transmission of schistosomiasis was interrupted in the province in 2019, which is the first province to achieve the national criteria of interruption of schistosomiasis transmission among the 5 provinces locating in the marshland and lake regions. In addition to political, economic and scientific and technical factors that greatly contribute to the huge achievements from schistosomiasis control in Jiangsu Province, the spiritual implication of Jiangsu schistosomiasis control culture that is mainly characterized by dedication, rigorousness, truth-seeking and innovation play a vital role in the schistosomiasis control program of Jiangsu Province, which encourages generations of schistosomiasis control professionals working in Jiangsu Province to fight against the "God of plague".

Abstract
Adherence to antiretroviral therapy (ART) is critical to achieving viral suppression. However, social determinants of health (SDoH) can undermine patient adherence to ART, resulting in drug resistance that compromises future treatment options. We assessed ART adherence and HIV-1 drug resistance at the national and state levels in the US and investigated their associations with SDoH and other HIV-related outcomes. Data were obtained from Symphony Health's Integrated Dataverse (IDV), Monogram/LabCorp Database, as well as national and publicly available databases, including Centers for Disease Control and Prevention (CDC), American Community Survey (ACS), and J. Kaiser Family Foundation (KFF). Inferential analyses were performed to investigate associations using patient-level data, and the results were reported by state and overall within the nation. Correlations between continuous variables were estimated by the Spearman's test, and that between continuous variable and categorical variable were estimated using one-way analysis of variance (ANOVA). State-level rates of poor adherence and resistance ranged from 26 to 55% and 20 to 54%, respectively. Female gender, non-white race, low education, poverty, and unemployment were associated with poor adherence; female gender was associated with drug resistance. Both adherence and resistance were correlated to HIV prevalence rates. Our findings suggest that US patients living with HIV face great challenges associated with poor ART adherence and HIV-1 drug resistance.

Abstract
OBJECTIVE This study aimed to explore the association of microRNA(miR)-146a and miR-146b expressions with risk, severity, in-hospital death of acute pancreatitis (AP). PATIENTS AND METHODS 50 severe AP (SAP) patients, 50 moderate-severe AP (MSAP) patients, 50 mild AP (MAP) patients and 50 healthy controls (HCs) were enrolled. Plasma samples were collected after the enrollment, then miR-146a and miR-146b expressions were detected by reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Ranson's score, Acute Physiology and Chronic Health Evaluation (APACHE) II score, sequential organ failure assessment (SOFA) score, C-reactive protein (CRP) as well as in-hospital mortality were assessed in AP patients. RESULTS Both miR-146a and miR-146b expressions were the highest in SAP patients, followed by MSAP patients, MAP patients and HCs. Meanwhile, they distinguished SAP, MSAP, MAP patients from HCs, and also distinguished SAP, MSAP and MAP patients from each other. In SAP, MSAP and MAP patients, MiR-146a positively correlated with Ranson's score, APACHE II score, SOFA score and CRP. Besides, miR-146b positively correlated with Ranson's score, APACHE II score, SOFA score and CRP in SAP patients; correlated with Ranson's score, APACHE II score and CRP in MSAP patients; and correlated with Ranson's score and SOFA score in MAP patients. Notably, miR-146a predicted increased in-hospital death risk of both SAP and MSAP patients, while miR-146b predicted raised in-hospital death risk of SAP patients but not MSAP patients. CONCLUSIONS Circulating miR-146a and miR-146b exhibit potential as markers for AP management and prognosis.

Abstract
Objective: To compare the clinical outcomes of one and two blastocysts in the freeze-thaw transplantation cycle. Methods: Totally 3 675 cycles of frozen thawed blastocyst transplantation in Reproductive Medical Center of the Second Nanning People's Hospital from January 2012 to December 2016 were analyzed retrospectively. According to the quantity and quality of transferred blastocysts, all the patient were divided into two groups: (1) one embryo group, including the single excellent group (one high quality blastocyst) and the single non excellent group (one non high quality blastocyst); (2) two embryo groups, including the double excellent group (two high quality blastocysts), the one excellent and one non excellent group (one high quality blastocyst+one non high quality blastocyst), and the two non excellent group (two non high quality blastocysts were transplanted). Then the patients were divided into subgroups according to their ages: less than 35 years old, 35-40 years old and over 40 years old. On this basis, the implantation rate, clinical pregnancy rate, multiple birth rate and live birth rate were compared. Results: (1) The implantation rate, clinical pregnancy rate, multiple birth rate, preterm birth rate and live birth rate were all significantly increased, while the abortion rate was significantly reduced in the double blastocyst group (all P<0.05). (2) In the group of<35 years old, the rates of multiple birth and preterm birth in the double blastocyst group were significantly higher than those in the single optimal group (P<0.01). (3) In the 35-40 years old group, the clinical pregnancy rate, multiple birth rate and live birth rate of the double excellent group were significantly higher than those of the single excellent group (P<0.01); while the clinical pregnancy rate and live birth rate of the one excellent and one non excellent group and the double non excellent group were not significantly different from those of the single excellent group (P>0.05), but the multiple birth rate and preterm birth rate were significantly increased (P<0.01). The clinical pregnancy rate, live birth rate and multiple birth rate of double non optimal group were significantly higher than those of single non optimal group (P<0.01). (4) In the group>40 years old, there were no significant differences in clinical pregnancy rate and live birth rate between the two groups (P>0.05). There were no significant differences in implantation rate, clinical pregnancy rate and live birth rate between double non optimal group and single non optimal group (P>0.05). Conclusion: No matter the age of the patients, if the couple have high quality blastocysts, we should give priority to single high quality blastocyst transplantation; even if they have no high quality blastocysts, we should also consider single blastocyst transplantation, in order to reduce the risk of multiple pregnancy and improve the cumulative live birth rate, so as to improve the pregnancy outcome.

Abstract
OBJECTIVE To examine early and late pregnancy loss in women with and without polycystic ovary syndrome (PCOS) undergoing IVF/ICSI transfers. DESIGN Retrospective cohort study. SETTING Reproductive medicine centre at a tertiary hospital. POPULATION We studied women with a positive β-human chorionic gonadotropin (β-hCG) after in vitro fertilisation/intra-cytoplasmic sperm injection (IVF/ICSI) treatment from May 2014 to April 2019. METHODS Odds ratios (OR) for early (≤13 weeks) and late (>13 weeks) pregnancy loss were calculated among women with and without PCOS for plurality of the pregnancy with adjustment for confounding factors. MAIN OUTCOME MEASURES Early pregnancy loss (EPL) and late pregnancy loss (LPL). RESULTS From 21 820 women identified with a positive β-hCG, 2357 (10.8%) women had PCOS, and 19 463 (89.2%) women did not. EPL occurred in 16.6% (391) of women with PCOS versus 18.3% (3565) in women with non-PCOS (OR 0.89, 95% CI 0.79-0.99, P = 0.04). After adjustment for age and other confounders, the rate of EPL was not statistically significantly associated with PCOS status (adjusted OR [aOR] 0.91, 95% CI 0.80-1.05). Women with PCOS demonstrated a higher rate of LPL (6.4% in PCOS versus 3.6% in non-PCOS, OR 1.81, 95% CI 1.48-2.21, P < 0.001). In multivariable analysis, the potential impact of PCOS was less strong (aOR 1.38, 95% CI 0.96-1.98), with BMI and maternal comorbidities also associated with LPL (aOR 1.08, 95% CI 1.04-1.1 and aOR 2.07, 95% CI 1.43-3.00, respectively). CONCLUSIONS Polycystic ovary syndrome was not independently associated with EPL. There was an increased risk of LPL but this difference was not statistically significant. TWEETABLE ABSTRACT Polycystic ovary syndrome women are at increased risk of late pregnancy loss, partly driven by elevated BMI and maternal comorbidities.

Abstract
OBJECTIVE MicroRNA-16 (miR-16) expression has been proved to take part in the initiation and development of several cancers, including hepatocellular carcinoma (HCC). However, its role and its molecular mechanism in HCC cells remain unclear. Our study aimed to elucidate miR-16 probable role and potential mechanism in HCC cells. PATIENTS AND METHODS MiR-16 expression in HCC was measured by Real Time-Polymerase Chain Reaction (RT-PCR). MiR-16 mimic or inhibitor was applied to increase or decrease miR-16 expression in Huh7 cells separately. The cell viability was measured by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide). The invaded cells and migrated cells were detected by the transwell assay. The epithelial-mesenchymal transition (EMT) and the nuclear factor-κB (NF-κB) were performed using Western blot. The tumor growth was measured via xenograft tumor formation assay. Moreover, bioinformatical methods and luciferase reporter assay were carried out to confirm the miR-16 target gene. RESULTS MiR-16 expression was downregulated in HCC tissues and cells. Furthermore, the increasing miR-16 expression was suppressed, whereas the decreasing miR-16 expression promoted cell proliferation, invasion, and migration in Huh7 cells. Moreover, miR-16 targeted FEAT in regulating HCC progression. FEAT was associated with a poor prognosis of HCC patients. Especially, miR-16 suppressed EMT and NF-κB pathway in HCC and inhibited the tumor growth in vivo. CONCLUSIONS We stated that miR-16 suppressed HCC cell progression by targeting FEAT and inhibiting EMT and NF-κB pathway. MiR-16 may be clinically utilized as a factor for the clinical diagnosis and prognosis of HCC.

Abstract
Abstract Objective To study the expression of the three autophagy-associated proteins, BECN1, LC3 and p62, after the injury of the skeletal muscle of rats and to explore its application in differentiation between antemortem and postmortem injury. Methods The 72 healthy Sprague-Dawley rats were randomly divided into the undamaged control group, the antemortem injury group (0.5 h, 1 h, 2 h, 4 h, 8 h, 16 h and 24 h) and postmortem injury group (0.5 h, 1 h, 2 h and 4 h). A model of the injured right hind limb of rats was constructed. The expressions of the autophagy-associated proteins, BECN1, LC3-2/LC3-1 and p62, in the control group, the antemortem injury group and postmortem injury group were detected by Western blotting method. The data were respectively centralized and standardized and the orthogonal partial least square-discrimination analysis (OPLS-DA) identification model of antemortem and postmortem injury groups was constructed. Results The expression of BECN1, p62 protein and LC3-2/LC3-1 after the injury of the skeletal muscle of the rats showed different degrees of changes, but the differences among the 3 groups had no statistical significance. Antemortem and postmortem injury groups can be distinguished by centralizing and standardizing the expression levels of autophagy protein BECN1 and the ratio of LC3-2/LC3-1. The principal components extracted from OPLS-DA model of antemortem injury and postmortem injury had a relatively good interpretation of the model (Rx2=0.563, Ry2=0.439), but it were less predictive (Q2=0.366). Conclusion The expression of BECN1 and the ratio of LC3-2/LC3-1 in injured local tissue of the rat skeletal muscle can be used for the differentiation of antemortem injury group and postmortem injury group.

Abstract
OBJECTIVE To investigate the expression and potential mechanism of GALNT10 in gastric cancer (GC). PATIENTS AND METHODS A total of 60 cases of GC tissues, as well as normal tissues were collected. The total RNA of GC specimens and cells were extracted by TRIzol method and the level of GALNT10 was examined by quantitative real-time polymerase chain reaction (qRT-PCR). In addition, the relationship between GALNT10 and clinical parameters and prognosis of GC patients was analyzed. Subsequently, Lentivirus was used to construct GALNT10 knockdown GC cell lines, and cell counting kit-8 (CCK-8) and transwell assays were applied to analyze the influence of GALNT10 on GC cell function. Bioinformatics and Luciferase assay was used to evaluate the relationship between GALNT10 and HOXD13. Furthermore, 5-fluorouracil (5-Fu)-resistant cells were used to detect the relationship between GALNT10 and 5-Fu sensitivity of GC cells. RESULTS qRT-PCR results revealed that GALNT10 level was markedly increased in tissues, as well as cell lines of GC. Statistical analysis suggested that GALNT10 expression was in close relation with the incidence of lymph node and distant metastasis along with poor prognosis in GC patients, but not with other indicators. CCK-8 and transwell migration experiment results indicated that GALNT10 silencing can inhibit the proliferative and migration ability of GC cells. Western blot results displayed that the HOXD13 level was remarkably decreased after GALNT10 knocking down. In addition, Luciferase gene assay indicated that GALNT10 could bind to HOXD13. Further rescue experiments showed that HOXD13overexpression can synergistically reverse the inhibitory effect of GALNT10 knockdown on GC cell proliferative and migration ability, which further demonstrated that GALNT10 could promote GC cell metastasis ability and reduce the sensitivity to 5-Fu by regulating HOXD13. CONCLUSIONS GALNT10 could regulate the proliferative and migration ability of GC cells and reduce the sensitivity to 5-Fu by enhancing the expression of HOXD13. Therefore, GALNT10 was expected to be a new therapeutic target for diagnosis of 5-fluorouracil resistance in GC.

Abstract
Objective: To explore the skin damage, oxidative damage and DNA damage of welding workers caused by ultra violet. Methods: From 1 May to 30 June 2017, 125 welding workers were selected as the contact group, which was divided into 2, 4, 6, 8 and 10-year-working age groups with 25 workers in each group and 25 healthy volunteers as the control group. The workers in the contact group were investigated with questionnaires on the distribution and wearing of protective equipment; the subjects in the two groups were examined in dermatology, and the peripheral blood was collected to detect the total antioxidant capacity (T-AOC) and DNA damage of mononuclear cells, and the influence of ultraviolet on the above indexes was analyzed. Results: The distribution rates of welding mask, dust mask and goggles were 100.0% (125/125) , 96.0% (120/125) , 98.4% (123/125) , respectively, and the distribution rates of welding gloves were 64.8% (81/125) ; the wearing rates of welding mask and goggles were 100.0% (125/125) , 90.4% (113/125) , and the wearing rates of dust mask and welding gloves were 89.6% (112/125) and 64.0% (80/125) , respectively. The acute skin injuries such as hand and face peeling and skin pruritus were serious in the 2-year-working age group, and the chronic skin injuries such as insensitive and numbness and verrucous vegetations were the main manifestations in the 10-year-working age group. Compared with the control group, T-AOC in peripheral blood of workers exposed to 6, 8 and 10 years decreased significantly, and DNA content in comet tail of workers exposed to various working years increased significantly (P<0.05) , while DNA content in comet tail increased with working years (F=1501.130, P<0.05) . Conclusion: UV welding can cause skin damage, reduce the antioxidant capacity of the body, and increase DNA damage with the increase of working age.

Abstract
The submental artery perforator flap (SAPF) has been a new option for the intraoral reconstruction of oral squamous cell carcinoma (OSCC) patients in recent years, but its surgical outcomes have not been well assessed. We compared the surgical outcomes and oncological safety of SAPF reconstruction for medium-sized soft-tissue defects after the ablation of primary oral cancer with traditional submental island flaps (SIF) and anterolateral thigh perforator flaps (ALTPF). Fifty-one SAPFs, 30 SIF, and 74 ALTPF were reviewed for the intraoral medium-sized reconstructions after the ablation of oral cancer from our institutional clinical oncological databases. We performed comparative assessments on the variables of surgical outcome and oncological safety among the 3 cohorts. A Kaplan-Meier estimate of survival for each flap was calculated. Operating time was significantly reduced in the SIF and SAPF groups than ALTPF (p = 0.021 and 0.014, respectively). Flap thickness of SAPF was the significantly thinnest (mean 0.5 cm) among three groups. The common complications of donor site for both SAPF and SIF group were incision dehiscence and orocutaneous fistula. There was no significant difference in disease-free survival (DFS) among the 3 groups. However, several OSCC patients with the SIF reconstruction were found to have recurrences with a metastatic lymph node under the flap after the first operation. SAPF could be a versatile choice of the intraoral reconstruction for the medium-sized soft-tissue defects after the ablation of oral cancer.

Abstract
Objective: To update the disease burden of colorectal cancer (CRC) in Chinese population by integrating the latest multi-source evidences. Methods: Groups of data from GLOBOCAN, series of Chinese Cancer Registry Annual Report (annual report), Cancer Incidence in Five Continents (CI5), Global Burden of Disease Project 2017 (GBD), China Death Cause Surveillance Datasets and China Health Statistical Yearbooks (yearbook) were used to extract the information. Data on incidence, mortality, disability-adjusted life year (DALY) and percentage distribution of sub-location of CRC were used to analyze the latest disease burden in China, and age-standardized rates by world standard population were mainly used. Joinpoint Trend Analysis Software 4.7.0.0 was applied for time trend analysis. Data related to the economic burden of CRC in China were gathered by literature review. Results: (1) Current status: according to the latest annual report, the incidence and mortality rates of CRC were 17.1 per 100 000 and 7.9 per 100 000, respectively among the covered registration sites in 2015. The incidence ratios of male to female and that of urban to rural were 1.5 and 1.4, with the mortality ratios were 1.6 and 1.4, respectively. Similar to data from the annual report, the mortality rate was reported as 6.9 per 100 000 in 2017 by the surveillance data sets. Data from the GBD project showed that, the DALYs caused by CRC in China in 2017 was 4.254 million person years (doubled compared with that of 1990), accounting for 22.4% of the global burden of CRC. (2) Time trends: according to the annual reports, from 2009 to 2015, the incidence rate and mortality rate of CRC in China decreased by 10.2% and 9.5%, respectively. The same trend was also observed in urban sites, but was opposite in rural areas (increased 20.0% in incidence and 15.2% in mortality). Results from the Joinpoint analysis showed that the averaged annual percentage change (AAPC) was estimated as -1.6% (P<0.05) in the national mortality rate. Similarly, in the incidence and mortality rates of urban sites appeared as AAPC=-1.5% and -1.4% (all P<0.05), but inversely in the incidence rate from the rural sites as AAPC=3.3% (P<0.05). The yearbook data showed a 9.8% increase in urban and 20.6% increase in rural on the mortality in 2017 when compared with 2004, but the Joinpoint analysis showed no statistical significance (P<0.05). (3) Distribution of sub-location of CRC: the annual report showed that among all the new CRC cases in China in 2015, colon, rectal and anal cancer accounted for 49.6%, 49.2% and 1.2%, respectively, while the proportions were 51.3%, 47.6% and 1.1%, respectively in 2009. The proportion of colon cancer was continuously higher in the urban (>52%) than that in the rural areas (<44%). The CI5 Ⅺ data showed that ascending and sigmoid colons were more commonly seen among all the colon cancers. (4) Economic burden: the average annual growth rate of the medical expenditure per CRC patient in China ranged from 6.9% to 9.2%, and the 1-year out-of-pocket expenditure of a newly diagnosed patient accounted for about 60% of their previous-year household income. Conclusions: In China, the overall disease burden of CRC might have been decreased slightly but generally remained stable in the last several years, however, the rising burden appeared in the rural areas should not be ignored. In consistent with findings from a previous review, men and people from the urban areas are considered the target populations for CRC. The finding of higher proportion of colon cancer in urban areas suggests the impact of development of socioeconomic and medical technologies on CRC development and detection. The economic burden of CRC continued to grow.

Abstract
Background In vitro studies of the changes about osteoblastogenesis and adipogenesis potential of BMSCs were not clear. As it is the critical pathway for osteogenic differentiation and bone formation, whether or not Wnt/β-catenin signalling is involved in the changes of osteogenic and adipogenic potential of BMSCs and participates in bone content decrease of ovariectomized (OVX)osteoporosis rats has been rarely reported. Material/Methods BMSCs from femurs of ovariectomzed rats were isolated and cultured in vitro. The proliferation potential of BMSCs was analysed by CCK-8 assays . Osteoblastic and adipogenic differentiation potential of the BMSCs was assessed by ALP activity assay, Alizarin red S staining, Oil red O staining and RT-PCR analysis. Results The results demonstrated that BMSCs from bilateral ovariectomization rats were endowed with lower proliferation and osteoblastic differentiation potential but higher adipogenic potential than the control group in vitro. In addition, β-catenin was found to have been decreased in OVX BMSCs, indicating that Wnt/β-catenin signalling pathways were suppressed in OVX BMSCs . Conclusions Results suggested that changes in the Wnt canonical signalling pathway may be related to imbalances of osteogenic and adipogenic potential of BMSCs, and this may be an important factor related to bone content decrease in ovariectomized osteoporosis rats.

Abstract
OBJECTIVE The aim of this study was to investigate the regulatory effect of long non-coding RNA (lncRNA) NKILA on autophagy in sepsis-induced kidney injury. MATERIALS AND METHODS Sepsis model was successfully established in rats by cecal ligation and puncture (CLP). Hematoxylin and eosin (HE) staining was performed to evaluate the pathological lesions in rat kidney tissues. Subsequently, serum samples of sepsis rats were collected. The levels of blood urea nitrogen (BUN) and serum creatinine (SCr) were determined. Western blot and quantitative real time-polymerase chain reaction (qRT-PCR) were conducted to detect the protein and mRNA expression levels of LC3, Beclin-1, activated caspase-3, p-Akt (308), p-Akt (472), Akt and NKILA in kidney tissues of sepsis rats at different time points, respectively. Subsequently, HK-2 cells were induced with different doses of lipopolysaccharide (LPS) for different time points. The expression levels of the above genes in cells were detected as well. Finally, changes in autophagy and apoptosis in LPS-induced HK-2 cells with the treatment of PI3K pathway inhibitor or Akt inhibitor were observed. RESULTS Typical pathological lesions were observed in kidney tissues of sepsis rats, with increased serum levels of BUN and SCr. This indicated the successful construction of the sepsis model in rats. The expression levels of LC3, Beclin-1, and NKILA/Akt significantly increased in kidney tissues of sepsis rats. In vitro experiments revealed that NKILA expression in HK-2 cells gradually up-regulated with the increase of LPS dose and prolongation of LPS induction. The expressions of LC3 and NKILA/Akt were higher at 10 mg/L LPS treatment, and 8 h of LPS induction. Furthermore, the treatment of PI3K pathway inhibitor or Akt inhibitor remarkably down-regulated LPS-induced LC3 expression, while it accelerated cell apoptosis and up-regulated NKILA expression. CONCLUSIONS Autophagy occurs at sepsis-induced kidney injury, which can be regulated by NKILA/Akt pathway.

Abstract
OBJECTIVE Acute respiratory distress syndrome (ARDS) threatens humans' health worldwide, causing huge labor and economic cost investment. This study aims to explore whether mesenchymal stem cells (MSCs) affect RDS in newborn swines via the Janus kinase-signal transducers and activators of transcription (JAK-STAT) signaling pathway by the establishment of the model of the disease. MATERIALS AND METHODS The phosphorylation of the JAK-STAT signal transduction proteins was first detected via Western blotting to verify the regulatory effect of MSCs on RDS in newborn swines through the JAK-STAT signaling pathway. Then, the Reverse Transcription-Polymerase Chain Reaction (RT-PCR) was utilized to analyze the influences of the injection of MSCs into the blood of newborn model RDS swines on inflammatory factors in vivo. To further demonstrate the signal transduction function put forwarded, the RT-PCR and enzyme-linked immunosorbent assay (ELISA) were adopted to analyze the influences of the JAK-STAT signaling pathway inhibitor on the expression of the signature proteins of RDS in newborn swines and the changes in the inflammatory factors. RESULTS MSCs induced the phosphorylation of JAK and STAT, and they activated the JAK-STAT signal transduction of RDS in newborn swines. Compared with those in normal saline group, the interleukin (IL)-2, IL-6, IL-8, and tumor necrosis factor-α (TNF-α) expression levels in MSC group were increased, namely, MSCs substantially promoted their expression levels (p<0.05), but those of IL-10 and IL-13 were significantly decreased (p<0.05). CONCLUSIONS The inhibitor of the JAK-STAT signaling pathway can suppress the therapeutic effect of MSCs on RDS in newborn swines.

Abstract
OBJECTIVE Diabetic ketoacidosis is one of the most serious acute complications of the gestational diabetes and is marked by the triad of the uncontrolled hyperglycemia, acidosis, and ketosis. Diabetic ketoacidosis can be a life-threatening emergency for mother and fetus, whose genetic factors resulting in diabetic ketoacidosis remain unclear. This study aimed to explore the correlation between SLC26A6 gene polymorphism rs184187143 and the risk of diabetic ketoacidosis of gestational diabetic mellitus (GDM). PATIENTS AND METHODS A total of 98 patients with GDM and 98 patients with diabetic ketoacidosis of GDM were enrolled. The direct sequencing of the products by Polymerase Chain Reactions of the extracted genomic DNA from the involved patients was performed to analyze the SLC26A6 gene polymorphism rs184187143, and the further genotype frequencies were compared to the statistical analysis of the clinical and biochemical data. RESULTS A significantly increased prevalence of the G allele (p = 0.032, OR = 2.326, 95% CI = 1.539-3.516), C/G genotype (p = 0.021, OR = 3.582, 95% CI = 1.216-10.558), and a previously uncharacterized rs184187143, was discovered in the diabetic ketoacidosis of the GDM group. The genotype of SLC26A6 rs184187143 was shown to be markedly associated with increased prevalence of the diabetic ketoacidosis of GDM. CONCLUSIONS Our study firstly established that the G allele and C/G genotype of rs184187143 single nucleotide polymorphism (SNP) in SLC26A6 gene was closely linked with the increased risk for the development of the diabetic ketoacidosis of GDM.

Abstract
Objective To develop mathematical models for skeletal age determination with multiple statistic method based on the correlation between age and the growth of the epiphysis of extremitas sternalis of clavicle in Shanxi adolescents. Methods The 562 Shanxi sternoclavicular joint samples (454 cases of modelling, 108 cases of external verification) were scanned by the thin-section computed tomography. After volume rendering was obtained, indicators such as area of epiphysis, area of metaphysis, longest diameter of epiphysis and longest diameter of metaphysis of both extremitas sternalis of clavicle were collected. Indicators such as the ratio of area of epiphysis to area of metaphysis, and the ratio of longest diameter of epiphysis to longest diameter of metaphysis of both sides were calculated. Then multiple linear regression and random forest discriminant models were used to build mathematical models for age determination of adolescents. Results The obtained indicators exhibited a strong correlation with age (r>0.85). The multiple linear regression model for males and females (all 4 indicators entering the model) based on the ratio of longest diameter of epiphysis to longest diameter of metaphysis and the ratio of area of epiphysis to area of metaphysis had an internal validation accuracy rate (±1.0 year) of over 92% and 108 cases had an external validation accuracy rate of over 70% (±1.0 year). The out of bag error rates of random forest discriminant models were less than 2% for people over 18.0 years old (≥18.0 years old) and under 18.0 years old. The external validation accuracy rates of the 108 cases were over 80%. Conclusion The regression and discriminant models established in this study have certain reliability and accuracy and can be used in age determination of Shanxi adolescents.

Abstract
OBJECTIVE Merlin is encoded by Neurofibromatosis type 2 gene (NF-2), a tumor suppressor gene, which causes some multiple tumors forming disease of the nervous system in case of function loss. Bioinformatics analysis suggested that patients with NF-2 mutation had a worse prognosis, while it was associated with PI3K/mTOR activation, implying abnormal apoptosis in NF-2 mutation related tumors. Hence, we supposed that the inhibitors of PI3K/mTOR pathway might play a role in suppressing the tumor proliferation. MATERIALS AND METHODS Two representative NF-2 mutation tumor model of NCI-H2452 and HEI193 cell lines were adopted, while two PI3K/mTOR pathway inhibitors Trametinib and Vistusertib were chosen to study the proliferation and apoptosis of the tumor cells. RESULTS CCK8 cell counting experiment showed that both Trametinib and Vistusertib could inhibit the proliferation of NCI-H2452 cell in vitro, while the combination of Trametinib and Vistusertib was more significant. Flow cytometry results showed that both Trametinib and Vistusertib could enhance apoptosis of NCI-H2452 cell in vitro, while the combination of Trametinib and Vistusertib was more significant. Similar results were also achieved for HEI193 cell lines. In vivo tumorigenicity experiments demonstrated that the tumor volume and weight were significantly decreased by both Trametinib and Vistusertib, while their combination had the most significant effect. Western blot results demonstrated that both Trametinib and Vistusertib could inhibit PI3K/mTOR /MEK pathway and enhance the expression of merlin. CONCLUSIONS We found that PI3K/mTOR inhibitor could decrease the proliferation of NF-2 mutation tumor cell lines by enhancing apoptosis, while the combination of two drugs might have a better effect.

Abstract
OBJECTIVE Mounting evidence indicates that long noncoding RNAs (lncRNAs) play a critical role in the tumorigenesis. Up-regulation of lncRNA LINC00662 (LINC00662) has previously confirmed in several tumors. However, the study of LINC00662 in prostate cancer (PCa) is limited. Hence, to determine the expression pattern and function of LINC00662 in PCa. PATIENTS AND METHODS LINC00662 expression was first detected in PCa cell lines and tissue samples by qRT-PCR. Based on follow-up data, correlations of LINC00662 expression and clinicopathological features, including overall survival, in PCa patients were evaluated. Cell proliferation, migration, invasion, and apoptosis were detected by CCK-8 assay, colony-forming assay, Wound-healing assay, transwell assay, and flow cytometry, respectively. Additionally, LINC00662-specific miRNA was further confirmed using the dual-luciferase reporter assay and RT-PCR. RESULTS LINC00662 was significantly upregulated in PCa tissues and cell lines compared with adjacent normal tissue and a normal prostate epithelial cell line. Higher expression of LINC00662 was positively associated with distant metastasis and shorter overall survival. In addition, multivariate analysis revealed that tissue LINC00662 expression was confirmed to be an independent prognostic factor for PCa. Furthermore, LINC00662 silencing inhibited the proliferation, migration, and invasion of PC-3 and LNCaP cells, and promoted apoptosis in vitro. Bioinformatics methods and luciferase reporter assay revealed the close link within miR-34a and 3'-untranslated region (UTR) of LINC00662 and further confirmed that LINC00662 could function as a sponge of miR-34a in PCa cells. Also, the results of RT-PCR showed that knockdown of LINC00662 suppressed the expression levels of miR-34a. CONCLUSIONS The current results further enhanced our understanding of the effects of LINC00662 in PCa and may help to provide a new potential target for PCa treatment.

Abstract
Objective: To identify the risk factors of non-sentinel lymph node (nSLN) metastasis in breast cancer patients with 1~2 positive axillary sentinel lymph node (SLN) and construct an accurate prediction model. Methods: Retrospective chart review was performed in 917 breast cancer patients who underwent surgery treatment between 2002 and 2017 and pathologically confirmed 1-2 positive SLNs. According to the date of surgery, patients were divided into training group (497 cases) and validation group (420 cases). A nomogram was built to predict nSLN metastasis and the accuracy of the model was validated. Results: Among the 917 patients, 251 (27.4%) had nSLN metastasis. Univariate analysis showed tumor grade, lymphovascular invasion (LVI), extra-capsular extension (ECE), the number of positive and negative SLN and macro-metastasis of SLN were associated with nSLN metastasis (all P<0.05). Multivariate Logistic regression analysis showed the numbers of positive SLN, negative SLN and macro-metastasis of SLN were independent predictors of nSLN metastasis (all P<0.05). A nomogram was constructed based on the 6 factors. The area under the receiver operating characteristic curve was 0.718 for the training group and 0.742 for the validation group. Conclusion: We have developed a nomogram that uses 6 risk factors commonly available to accurately estimate the likelihood of nSLN metastasis for individual patient, which might be helpful for radiation oncologists to make a decision on regional nodal irradiation.

Abstract
OBJECTIVE Hepatocellular carcinoma (HCC) is a common malignant tumor that poses a serious threat to human health and life. Metastasis is one of the reasons for high rate of relapse. Due to the lack of effective treatment, the prognosis of HCC patients is far from satisfactory. The aim of this study was to investigate the role of long non-coding RNA (lncRNA)-TPTE2P1 in HCC development. Moreover, we aimed to search for new biomarkers which could predict the metastasis and provide novel therapeutic strategies for HCC. PATIENTS AND METHODS Quantitative real-time polymerase chain reaction (qRT-PCR) was used to evaluate the expression level of lncRNA-TPTE2P1 in both HCC tissues and cell lines. Wound-healing assay and transwell assay were applied to determine the ability of cell migration. Meanwhile, transwell matrigel assay was applied to detect the invasion of HCC cells. The protein expressions of E-cadherin, Vimentin and N-cadherin in chosen cell lines were detected by Western blotting. RESULTS Results found that lncRNA-TPTE2P1 was overexpressed in both HCC tissues and cell lines. Further analysis revealed that overexpression of lncRNA-TPTE2P1 was correlated with tumor size, distant metastasis, differentiation degree, as well as tumor node metastasis (TNM) stage of HCC patients. Subsequent wound-healing assay, transwell assay and Matrigel assay confirmed that down-regulated lncRNA-TPTE2P1 could significantly suppress the invasion and migration of cells. However, up-regulation of lncRNA-TPTE2P1 showed the opposite results. Moreover, lowly expressed lncRNA-TPTE2P1 significantly decreased the protein levels of E-cadherin, Vimentin and N-cadherin. These results indicated that lncRNA-TPTE2P1 might stimulate the migration and invasion of HCC cells by promoting epithelial-mesenchymal transition (EMT). CONCLUSIONS In summary, our results suggested that lncRNA-TPTE2P1 functioned as an oncogene in HCC. Meanwhile, lncRNA-TPTE2P1 stimulated HCC cell migration and invasion by promoting EMT. LncRNA-TPTE2P1 might play a vital role in the development and progression of HCC. Our findings demonstrated that lncRNA-TPTE2P1 could serve as an early biomarker of metastasis and therapeutic target for HCC.

Abstract
Objective: To assess the treatment and prognosis of vulvar melanoma. Methods: A total of 59 cases of primary vulvar melanoma admitted to Cancer Hospital of Peking Union Medical College, Chinese Academy of Medical Sciences from January 1st, 1981 to November 30th, 2019 were collected. The clinical characteristics, treatment, survival and prognostic factors of vulvar melanoma were analyzed retrospectively. The end date of follow-up was January 15th, 2020.The median follow-up time was 26.0 months (range:2-198 months). Results: (1) Clinical characteristics: the median age of 59 patients with vulvar melanoma was 56 years old (range:18-83 years old). According to the American Joint Committee on Cancer stage manual, there were 18, 7, 26 and 8 cases of stage Ⅰ, Ⅱ, Ⅲ and Ⅳ respectively. The lesion of 38 cases was single and the other 21 cases were multiple. The largest diameter of the tumor ranged from 0.3 to 17.0 cm.The surface of the lesion was ulcerated in 17 cases. (2) Treatment: a total of 59 cases with vulvar melanoma, 56 patients received surgery, 36 cases of them received radical resection of vulva and 20 received local extended resection of vulvar tumor due to unilateral vulva lesion. Three patients did not receive surgery,one received chemotherapy combined with interferon, one received interferon, and one received radiotherapy. Lymph node management: among the 56 patients treated by surgery, 37 patients received inguinal lymphadenectomy, 24 (65%, 24/37) of whom were confirmed with inguinal lymph node metastasis by postoperative pathological examination. Inguinal lymph nodes enlargement were not found in 19 cases by preoperative imaging and clinical examination. In these 19 patients, three patients received inguinal lymph node biopsy, among them, one (1/3) patient was confirmed with inguinal lymph node metastasis by postoperative pathological examination, and the remaining 16 patients did not receive inguinal lymph node surgery. Postoperative adjuvant treatment: among the 56 patients who received surgery, 31 received adjuvant chemotherapy,one received adjuvant radiotherapy, four received interferon therapy, 17 received combination therapy including chemotherapy, and three did not receive postoperative adjuvant therapy. (3) Survival:during the follow-up period, the median survival time of 59 patients with vulvar melanoma was 30.0 months (range:2.0-198.0 months). The 3-year survival rate was 42.5%, and the 5-year survival rate was 23.8%. The median survival time of stage Ⅰ, Ⅱ, Ⅲ and Ⅳ were 72.0, 45.0, 24.0 and 23.0 months, respectively. The difference among stage Ⅰ, Ⅱ and stage Ⅲ, Ⅳ were statistically significant (P<0.01). The median survival time of patients undergoing radical resection of the vulva (35.0 months) and local enlarged tumor resection (29.0 months) were significantly longer than that of patients without surgery (9.0 months, P<0.01). The median survival time of the patients who underwent inguinal lymphadenectomy, lymph node biopsy and those who did not undergo surgery were 35.0, 32.0 and 30.0 months, respectively. There were no significant differences among the 3 groups (P>0.05). The median survival time of postoperative adjuvant chemotherapy patients (49.0 months) were significantly longer than that of postoperative adjuvant radiotherapy, interferon,and combination therapy including chemotherapy (9.0, 14.0 and 26.0 months, respectively, all P<0.01). (4) Prognostic factors: the univariate analysis showed that stage, vulvar operation and postoperative adjuvant treatment were the risk factors affecting the prognosis of patients with vulvar melanoma (P<0.01). Multivariate analysis revealed that stage alone was an independent risk factor affecting the prognosis of patients with vulvar melanoma (P<0.01). Conclusions: The prognosis of patients with vulvar melanoma is poor, and stage is an independent prognostic factor.Surgery combined with postoperative adjuvant chemotherapy may achieve relatively good results.

Abstract
The most fascinating feature of certain two-dimensional (2D) gapless quantum spin liquid (QSL) is that their spinon excitations behave like the fermionic carriers of a paramagnetic metal. The spinon Fermi surface is then expected to produce a linear increase of the thermal conductivity with temperature that should manifest via a residual value (κ0/T) in the zero-temperature limit. However, this linear in T behavior has been reported for very few QSL candidates. Here, we studied the ultralow-temperature thermal conductivity of an effective spin-1/2 triangular QSL candidate Na2BaCo(PO4)2, which has an antiferromagnetic order at very low temperature (TN ~ 148 mK), and observed a finite κ0/T extrapolated from the data above TN. Moreover, while approaching zero temperature, it exhibits series of quantum spin state transitions with applied field along the c axis. These observations indicate that Na2BaCo(PO4)2 possibly behaves as a gapless QSL with itinerant spin excitations above TN and its strong quantum spin fluctuations persist below TN.

Abstract
OBJECTIVE To evaluate the association between blood test parameters and intensity of Plasmodium falciparum infections among imported falciparum malaria cases in Tianjin City from 2015 to 2019, so as to provide insights into the early diagnosis of imported P. falciparum malaria. METHODS The epidemiological data of 37 imported cases with confirmed diagnosis of P. falciparum malaria in Tianjin City from 2015 to 2019 were collected, and the epidemiological features and clinical manifestations were retrospectively analyzed. In addition, the association between blood test parameters and intensity of P. falciparum infections was evaluated among the imported P. falciparum malaria cases. RESULTS Among the 31 imported P. falciparum malaria cases, there were 31 cases (83.8%) with a reduction in platelet (PLT) counts, 16 cases (43.2%) with a reduction in red blood cell (RBC) counts, 16 cases (43.2%) with a reduction in hemoglobin (Hb) concentrations, 23 cases (62.2%) with a rise in neutrophil percentage (NEUT%), 32 cases (86.5%) with a rise in total bilirubin (TBIL) concentrations, 29 cases (78.4%) with a rise in alanine aminotransferase (ALT) concentrations, 28 cases (75.7%) with a rise in aspartate transaminase (AST) concentrations, and 23 cases (62.2%) with a rise in gamma-glutamyl transpetidase (GGT) concentrations. The PLT count and Hb concentration correlated negatively with the intensity of P. falciparum infections (Goodman-Kruskal γ = -0.568 and -0.521, both P values < 0.05) and the TBIL concentration and NEUT% correlated positively with the intensity of P. falciparum infections (Goodman-Kruskal γ = 0.496 and 0.610, both P values < 0.05) among imported falciparum malaria cases; however, there were no associations of ALT, AST, GGT levels or RBC count with the intensity of P. falciparum infections among the imported falciparum malaria cases (Goodman-Kruskal γ = 0.370, 0.497, 0.314 and -0.434, all P values > 0.05). CONCLUSIONS PLT, Hb, TBIL and NEUT% may serve as markers for early auxiliary diagnosis of imported P. falciparum malaria, and PLT and TBIL may provide valuable information for the diagnosis of severe imported P. falciparum malaria.

Abstract
Objective: The cellular immunity of 5 Mycobacterium tuberculosis recombinant proteins and their compositions was evaluated. Method: A total of 88 fresh venous blood from peripheral heparin anticoagulant population, 42 of which were from tuberculosis patients treated by The Tuberculosis Prevention and Treatment Center of Changping District, Beijing, and 46 of healthy volunteers were provided by the Infection Diseases of Chinese Center for Disease Control and Prevention. Healthy volunteers without a history of tuberculosis exposure and any clinical signs and symptoms. Using the Mycobacterium tuberculosis standard strain H37Rv DNA as a template, complete genes of the selected 5 recombinant proteins Rv3874, Rv3875, Rv2031c, Rv1411c and Rv3418c by PCR amplified; 5 recombinant proteins were cloned, expressed and purified as stimulants by genetic recombination and protein purification techniques, and the effector T cell enzyme-linked immunospot assay (ELISPOT) was used to detect cellular immunity in the population. Results: The recombinant proteins Rv3874, Rv3875, Rv2031c, Rv1411c and Rv3418c were successfully cloned, expressed and purified; And the sensitivities were 50.00%, 71.43%, 69.04%, 73.81% and 76.19%, and the specificities were 86.96%, 76.09%, 71.74%, 39.13% and 36.96%. In addition, the positive predictive value, negative predictive value, area under the curve and Youden index were 52.46% to 77.78%, 62.96% to 74.47%, 0.511 to 0.754 and 0.129 to 0.475, respectively. Except for Rv1411c and Rv3418c, the number of spot-forming cell (SFC) detected by Rv3874, Rv3875 and Rv2031c in tuberculosis patients was higher than healthy volunteers, and the differences were statistically significant (P<0.001). Among the 26 compositions composed of 5 recombinant proteins, the sensitivity was 80.95% to 95.24%, and the specificity was 68.89% to 24.44%. As the number of recombinant proteins in the composition increases, the sensitivity gradually increased, but the specificity decreased. Conclusion: The recombinant proteins of Mycobacterium tuberculosis Rv3874, Rv3875 and Rv2031c have strong ability to stimulate T cells to produce immune response, and have certain antigenicity. The efficacy of Rv1411c and Rv3418c alone as diagnostic antigens is not ideal, and the composition composed of multi-component antigens has certain application value. This article provides experimental evidence for the immune diagnosis of tuberculosis and the preparation of new anti-tuberculosis vaccines.

Abstract
OBJECTIVE This study evaluates the efficacy of statin-ezetimibe co-therapy compared to statin monotherapy in reducing cardiovascular and/or cerebrovascular disease (CVD) prevalence in diabetes and non-diabetes patients. PATIENTS AND METHODS Literature search was conducted in electronic databases and study selection was based on pre-determined eligibility criteria. Random-effects metanalyses were performed to examine the risk of CVD incidence between statin-ezetimibe co-therapy and statin monotherapy and subgroups were performed to examine the significance of differences between diabetic and non-diabetic individuals. A pooled analysis of hazard ratios of statin-ezetimibe combination versus statin monotherapy in the prevalence of CVD reported by the individual studies was also performed. RESULTS 8 studies (136893 individuals; 80790 diabetics, 85555 non-diabetics; age 63.5 years [95% confidence interval (CI) 61.2, 65.8]; 61.5% [95% CI 55.2, 67.8] males) were included. Follow-up duration was 45 months [95% CI 27.5, 62.5]. Risk of CVD prevalence was significantly less with ezetimibe-statin than with statin alone in both diabetes (RR 0.69 [95% CI 0.67, 0.73]; p<0.00001) and in non-diabetes (RR 0.68 [95% CI 0.52, 0.90]; p=0.006) subjects (subgroup difference: chi2=0.00; p=0.97). Risk of prevalence of stroke was significantly less with ezetimibe-statin than with statin monotherapy in diabetes (RR 0.74 [95% CI 0.56, 0.98]; p=0.03) but non-significantly less in non-diabetes patients (RR 0.74 [95% CI 0.39, 1.41]; p=0.39) and this sub-group difference was also not statistically significant (chi2=0.00; p=0.99). CONCLUSIONS Statin-ezetimibe co-therapy is found more efficacious than statin monotherapy in reducing the incidence of CVD with no significant difference between diabetic and non-diabetic individuals.

Abstract
Objective: To investigate the effect of intestinal preparation on the efficacy and complications of fecal microbiota transplantation (FMT). Methods: A retrospective cohort study was performed. Clinical and follow-up data of 1501 patients who received FMT in the department of Colorectal Disease Specialty, Intestinal Microecology Diagnosis and Treatment Center, the Tenth People's Hospital, Tongji University from February 2018 to June 2019 were collected retrospectively. According to the intestinal preparation before FMT treatment, patients were divided into non-intestinal preparation group (n=216), antibiotic pretreatment group (n=383), intestinal cleansing group (n=267), and antibiotic combined with intestinal cleansing group (n=635). The adverse reactions after FMT treatment and the effective rates at 4-week and 8-week after treatment among the groups were compared. Patients, who repeated FMT treatment in the 3rd month and the 6th month due to reduced efficacy or ineffectiveness were divided into two subgroups: without intestinal preparation group and with intestinal preparation group. The effective rates of the two subgroups were compared. Results: Of the 1501 cases, 588 were male and 913 were female with mean age of (43.3±13.7) years and body mass index of (20.2±2.1) kg/m(2). Transplantation course was (3.3±1.7) weeks. The underlying diseases mainly included constipation (n=564), Crohn's disease (n=157), ulcerative colitis (n=142), irritable bowel syndrome (n=158), recurrent C. difficile infection (CDI) (n=106), autism (n=84), radiation intestinal injury (n=133), radiation enteritis (n=133), and non-CDI chronic diarrhea (n=60); the remaining cases (n=155). Baseline data among the 4 groups were not significantly different (all P>0.05). The overall morbidity of complication was 31.1% (467/1501), including 41 cases of vomiting (2.7%), 91 of nausea (6.1%), 49 of diarrhea (3.3%), 41 of abdominal pain (2.7%), 79 of bloating (5.3%), 72 of throat pain (4.8%), 38 of dizziness (2.5%), 51 of fever (3.4%), 3 of pulmonary infection (0.2%) and 2 of intestinal infection (0.1%). The above symptoms disappeared after symptomatic treatment. There was no statistically significant difference in the incidence of adverse reactions among the 4 groups (P>0.05). After 4-week of FMT treatment, the overall effective rate was 63.5% (902/1420); the effective rate of non-intestinal preparation group, antibiotic pretreatment group, intestinal cleaning group, and antibiotic combined with intestinal cleansing groupwas 57.6% (114/198), 64.2% (231/360), 60.2% (154/265) and 66.5% (403/606), respectively, with no statistically significant difference (χ(2)=6.659, P=0.084). After 8-week of FMT treatment, the overall effective rate was 61.3% (729/1293); the effective rate of non-intestinal preparation group, antibiotic pretreatment group, intestinal cleaning group, and antibiotic combined with intestinal cleansing group was 54.0% (88/163), 62.2% (202/325), 57.4% (132/230) and 64.4% (370/575), respectively, with no statistically significant difference (χ(2)=13.620, P=0.003). The effective rates of antibiotic combined with intestinal cleansing group and antibiotic pretreatment group were obviously higher than that of non-intestinal preparation group (χ(2)=5.789, P=0.016; χ(2)=10.117, P=0.001). Subgroup analysis showed that in the third month, the effective rate at 4-week after treatment was 60.1% (184/306) in the without intestinal preparation group and 61.5% (115/187) in the with intestinal preparation group, whose difference was not significant (χ(2)=0.091, P=0.763); however, in the sixth month, the effective rate at 4-week after treatment was 51.4% (89/173) in the without intestinal preparation group and 61.2% (161/263) in the with intestinal preparationgroup, whose difference was significant (χ(2)=4.229, P=0.040). Conclusions: FMT treatment is safe and effective. The combination of antibiotics and intestinal cleaning can improve overall efficacy of FMT. For patients who need repeated FMT treatment, the combination of antibiotics and intestinal cleaning program within 3 months has no significant effect on the effective rate, but in the sixth month, combinedpreparation is necessary.

Abstract
Objective: To examine the association between the clinical efficacy of fecal microbiota transplantation (FMT) in recipients and the choice of donor, and to observe the characteristics of intestinal flora and metabolites among different donors. Methods: A retrospective case-control study was conducted. Donor whose feces was administrated for more than 30 recipients was enrolled. Data of 20 FMT donors and corresponding recipients at Intestinal Microecology Diagnosis and Treatment Center of the Tenth People's Hospital from October 2018 to December 2019 were collected retrospectively. During follow-up, the efficacy of each recipient 8-week after FMT treatment was recorded and analyzed. Based on the efficacy of each donor, the donors were divided into three groups: high efficacy group (effective rate >60%, 10 donors), moderate efficacy group (effective rate 30%-60%, 6 donors) and low efficacy group (effective rate <30%, 4 donors). The structure of the bacterial flora and the content of fecal short-chain fatty acids in each group of donors were detected and compared among groups. Association of the efficacy of each donor group with the morbidity of complications, and association of efficacy of recipients with donors were analyzed. The evaluation indicators of FMT efficacy included objective clinical effectiveness and/or subjective effectiveness. Objective effectiveness indicated clinical cure plus clinical improvement, and subjective effectiveness indicated marked effectiveness plus medium effectiveness through questionnaire during follow-up. Results: A total of 1387 recipients were treated by 20 donors, including 749 cases of chronic constipation, 141 cases of chronic diarrhea, 107 cases of inflammatory bowel disease (IBD), 121 cases of irritable bowel syndrome (IBS), 83 cases of autism, and 186 cases of other diseases, such as radiation bowel injury, intestinal pseudo-obstruction, paralytic intestinal obstruction, functional bloating and allergic diseases. There were 829 cases, 403 cases, and 155 cases in high efficacy group, moderate efficacy group and low efficacy group respectively. Baseline data among 3 groups were not significantly different (all P> 0.05). In comparison of bacterial abundance (operational taxonomic unit, OTU) among different effective donor groups, the high efficacy group was the highest (330.68±57.28), the moderate efficacy group was the second (237.79±41.89), and the low efficacy group was the lowest (160.60±49.61), whose difference was statistically significant (F=16.910, P<0.001). In comparison of bacterial diversity (Shannon index), the high efficacy group and the moderate efficacy group were higher (2.96±0.36 and 2.67±0.54, respectively), and the low efficacy group was lower (2.09±0.55), whose difference was statistically significant (F=5.255, P=0.017). In comparison of butyric acid content among three groups, the high efficacy group had the highest [(59.20±9.00) μmol/g], followed by middle efficacy group [(46.92±9.48) μmol/g], and the low efficacy group had the lowest [(37.23±5.03) μmol/g], whose difference was statistically significant (F=10.383, P=0.001). The differences of acetic acid and propionic acid among three groups were not statistically significant (all P>0.05). A total of 418 cases developed complications (30.1%). Morbidity of complication in low efficacy group, moderate efficacy group and high efficacy group was 40.6% (63/155), 30.0% (121/403) and 28.2% (243/829) respectively, and the difference was statistically significant (χ(2)=9.568, P=0.008). The incidence of diarrhea in low efficacy group, moderate efficacy group and high efficacy group was 7.1% (11/155), 4.0% (16/403) and 2.8% (23/829) respectively, and the difference was statistically significant (χ(2)=7.239, P=0.027). Comparing the incidences of other types of complications, no statistically significant differences were found (all P>0.05). Follow up began 8 weeks after the FMT treatment. The total follow-up rate was 83.6% (1160/1387). The overall effective rate 58.3% (676/1160). Effective rates of various diseases were as follows: chronic constipation 54.3% (328/604), chronic diarrhea 88.5% (115/130), IBD 56.1% (55/98), IBS 55.1% (59/107), autism 61.6% (45/73), and other diseases 50.0% (74/148). Comparing the effective rate of three groups of donors for different diseases, there was no statistically significant difference in chronic diarrhea (P>0.05); there was a positive correlation trend in IBD, IBS and autism, but the differences were not statistically significant (all P>0.05). For chronic constipation and other diseases, high efficacy group had the highest effective rate [65.0% (243/374) and 63.2% (55/87)], followed by moderate efficacy group [49.4% (86/174) and 38.1% (16/42)], and low efficacy group had the lowest [16.1% (9/56) and 15.8% (3/19)], whose differences were significant (all P<0.05). Conclusions: Different donors have different efficacy in different diseases. Chronic constipation, radiation bowel injury, etc. need to choose donors with high efficacy. IBD, IBS and autism may also be related to the effectiveness of donors, while chronic diarrhea is not associated to the donor. The efficiency of the donor is negatively correlated to the morbidity of complications. The abundance and diversity of intestinal flora and the content of butyric acid may affect the efficacy of the donor.

Abstract
Objective: To evaluate the efficacy and safety of the fecal microbiota transplantation (FMT) in the different route administration for slow transit constipation (STC). Methods: A retrospective cohort study was conducted. The clinical data of 270 STC patients who voluntarily received FMT treatment in the Tenth People's Hospital of Tongji University from May 2018 to May 2019 were collected. Non-relative healthy adult standard donors were applied. The treatment routes of bacterial flora transplantation included nasojejunal tube (nasal enteral tube group, 120 cases), oral enterobacterial capsule treatment (oral capsule group, 120 cases), and colonoscopy infusion (colonoscopy group, 30 cases). The efficacy and safety of treatment among the three groups were compared. Results: Transplanted bacteria of three groups were extracted from 100 g of fresh feces. All the patients successfully completed the transplantation. The waiting time for the nasal enteral tube group, oral capsule group and colonoscopy group was (1.5±0.5) d, (0.4±0.3) d and (3.6±0.8) d respectively; the cost of establishing the transplantation path was (495±20) yuan, (25±10) yuan and (1420±45) yuan respectively, whose differences were statistically significant (F=9.210, P=0.03; F=10.600,P=0.01). The clinical improvement rates at 1 month after FMT treatment in the nasojejunal tube group, oral capsule group and colonoscopy group were 74.2% (89/120), 60.0% (72/120) and 53.3% (16/30) respectively, whose difference was statistically significant (χ(2)=5.990, P<0.05). The clinical improvement rates at 3 months after treatment were 71.1% (69/97), 53.6% (45/84), and 44.0% (11/25) respectively, whose difference was statistically significant (χ(2)=7.620, P<0.05). The incidence of adverse reactions in the colonoscopy group was 76.7% (23/30), which was higher than that in the nasal nasojejunal group (39.2%, 47/120) and oral capsule group (21.7%, 26/120). The most common adverse reactions in the nasojejunal tube group, oral capsule group and colonoscopy group were respiratory discomfort (17.5%, 21/120), nausea and vomiting (10.0%, 12/120), and diarrhea (36.7%, 11/30). During the 3-month follow-up after treatment, no FMT-related adverse reactions were reported. Conclusions: The nasojejunal tube route has stable clinical efficacy and operability, while the oral capsule route has shorter waiting time and less cost. However, the adverse reactions caused by different transplantation methods are different, thus personalized transplantation method should be recommended.

Abstract
The precise measurement of cosmic-ray antinuclei serves as an important means for identifying the nature of dark matter and other new astrophysical phenomena, and could be used with other cosmic-ray species to understand cosmic-ray production and propagation in the Galaxy. For instance, low-energy antideuterons would provide a "smoking gun" signature of dark matter annihilation or decay, essentially free of astrophysical background. Studies in recent years have emphasized that models for cosmic-ray antideuterons must be considered together with the abundant cosmic antiprotons and any potential observation of antihelium. Therefore, a second dedicated Antideuteron Workshop was organized at UCLA in March 2019, bringing together a community of theorists and experimentalists to review the status of current observations of cosmic-ray antinuclei, the theoretical work towards understanding these signatures, and the potential of upcoming measurements to illuminate ongoing controversies. This review aims to synthesize this recent work and present implications for the upcoming decade of antinuclei observations and searches. This includes discussion of a possible dark matter signature in the AMS-02 antiproton spectrum, the most recent limits from BESS Polar-II on the cosmic antideuteron flux, and reports of candidate antihelium events by AMS-02; recent collider and cosmic-ray measurements relevant for antinuclei production models; the state of cosmic-ray transport models in light of AMS-02 and Voyager data; and the prospects for upcoming experiments, such as GAPS. This provides a roadmap for progress on cosmic antinuclei signatures of dark matter in the coming years.

Abstract
OBJECTIVE: To quantify the relationship between strength and endurance of knee extensor and flexor and exercise capacity in patients with chronic obstructive pulmonary disease (COPD).METHODS: A total of 108 patients with stable COPD (age: 65 years, IQR25-75: 59-72) were enrolled in this cross-sectional study. Knee extensor and flexor function was evaluated using the isokinetic test, and the parameters attained were considered as independent variables. Exercise capacity was evaluated using 6-minute walking test (6MWT) and 30-second sit-to-stand test (30s SST), and the results were considered as dependent variables. The association between lower-limb muscle function and exercise capacity was assessed using multiple regression analysis.RESULTS: The patients mostly had moderate-to-severe airflow obstruction with a post-bronchodilator forced expiratory volume in 1 second (FEV1) of 57.87 ± 17.71% predicted. In multiple regression analysis, flexor total work (TW), extensor endurance ratio (ER), age and FEV1%pred were significantly associated with 6MWT (adjusted R² = 0.455, P < 0.001). Flexor TW and age were significantly associated with 30s SST (adjusted R² = 0.355, P < 0.001).CONCLUSION: Knee endurance has a significant relationship with exercise capacity, and knee flexor endurance seems to be an important factor contributing to exercise capacity in COPD patients.

Abstract
Objective: To evaluate the incidence of early cardiac injury in patients with left-sided breast cancer receiving hypofractionated radiotherapy after breast conserving surgery, and to investigate the correlation between cardiac injury and hypofractionated radiotherapy dose. Methods: We prospectively enrolled 103 breast cancer patients who received whole breast with or without regional nodal irradiation after breast conserving surgery using either deep inspiration breath-hold (DIBH) or free breathing (FB) radiotherapy technique. Cardiac examinations that included N-terminal pro-B-type natriuretic peptide (NT-proBNP), electrocardiogram, and myocardial perfusion imaging were performed routinely before and after radiotherapy. The effects of heart dose, systemic therapy and individual factors (Framingham score) on the incidence of cardiac events were analyzed. Results: The median age was 48 years. The mean dose (Dmean) of the heart, left anterior descending coronary artery (LAD), left ventricular (LV), and right ventricular (RV) were 4.0, 16.9, 6.3, and 4.4 Gy, respectively. With a median follow-up of 13.4 months, no patient had clinical cardiac abnormalities. The incidence rates of subclinical cardiac events at 1- 6- and 12-month were 23.5%, 31.6%, and 41.3%, respectively. The DIBH group had a lower mean dose, maximum dose, and V5-V40 in the heart, LAD, LV, and RV than the FB group (P<0.001). Univariate analysis showed an increased incidence of subclinical cardiac events with heart Dmean >4 Gy, LAD V40 > 20%, LV Dmean >6 Gy, RV Dmean >7 Gy, or cumulative doses of anthracycline or taxane > 300 mg/m(2) (All P<0.05). Anti-HER2 targeted therapy, endocrine therapy and Framingham score were not associated with the incidence of subclinical cardiac events (all P>0.05). Multivariate analysis demonstrated that Dmean of LV and RV were independently associated with the increased incidence of subclinical cardiac events. Conclusions: Early subclinical heart injury are found in patients with left-sided breast cancer after hypofractionated radiotherapy. The increased incidence of subclinical cardiac events after radiotherapy is positively associated with the cardiac radiation doses.

Abstract
As an innovative therapy, FMT has made a breakthrough in the treatment of recurrent Clostridium difficile infection (CDI). With the rapid development of biotechnology, the relationship between intestinal microflora and diseases has been gradually eluciated. Great hope has also been given to FMT in other intestinal and extraintestinal diseases with ineffective traditional treatment. However, as a new therapy method, FMT still has many unknown fields, such as the selection of clinical donors, the preparation of standardized bacterial solution and capsule, the selection of indications, the matching of donor and receptor, and the prevention and treatment of complications. Since 2012, our center has carried out treatment research and practice of FMT, so far with more than 60 000 FMTs for more than 3500 cases. Based on large sample data and experience, this special issue reports and discusses the above topics, and focuses on the establishment and clinical application of standardized methodology of FMT, which will undoubtedly play a positive role in promoting the healthy development of FMT treatment in China.

Abstract
Inflammatory bowel disease (IBD) is a group of chronic, recurrent, and inflammatory intestinal diseases. At present, it is believed that the destruction of intestinal homeostasis may be the cause of the onset and progression of IBD. Under normal circumstances, the maintenance of intestinal homeostasis depends on the balance among the intestinal microbes, the intestinal mucosal barrier, and the immune system. Accordingly, the treatment strategy for IBD must take into account micro-ecological reconstruction, immune regulation and intestinal barrier function recovery. Because different patients have different responses to incentives, different treatments, or those at different stages of the disease course show different disease behaviors, multidisciplinary collaboration seems quite necessary. This article aims to introduce a five-in-one integrated treatment strategy, including microecological treatment, immunotherapy, enteral nutrition, interventional therapy, and surgical treatment.

Abstract
In 2018, the myopia detection rate of children and adolescents aged 5-18 years old in Shaanxi Province was 54.9% (11 060/20 144). The myopia detection rate of girls [58.6%(5 830/9 949)] was higher than that of boys [58.6% (3 416/5 830)] (P<0.001). In children and adolescents, the myopia detection rate increased with the age before their 16 years old, and saw a stable or downward trend after the age of 16. After adjusting the confounding factors, the myopia detection rate of children and adolescents from regions with per capita GDP>100 000 yuan was higherthan that of children and adolescents from regions with per capita GDP<50 000 yuan[OR (95%CI):1.58(1.34-1.87)].

Abstract
Objective: To investigate the association between total cholesterol (TC) and primary liver cancer in Chinese males. Methods: Since May 2006, all the male workers, including the employees and the retirees in Kailuan Group were recruited in the Kailuan male dynamic cohort study. Information about demographics, medical history and TC levels was collected at the baseline interview, as well as information on newly-diagnosed primary liver cancer cases during the follow-up period. A total of 110 612 males were recruited in the cohort by 31 December 2015. TC levels were divided into four categories by quartile (<4.27, 4.27-4.90, 4.90-5.56 and ≥5.56 mmol/L), with the first quartile group serving as the referent category. Cox proportional hazards regression model was used to evaluate the association between TC levels and primary liver cancer risk. Results: By December 31, 2015, a follow-up of 861 711.45 person-years was made with a median follow-up period of 8.83 years. During the follow-up, 355 primary liver cancer cases were identified. Compared with the first quartile, the HR of incident primary liver cancer among participants with the second, third and highest quartile TC levels were 0.76 (95%CI: 0.58-1.01), 0.59 (95%CI: 0.43-0.79), and 0.36 (95%CI: 0.25-0.52), respectively after adjusting for age, educational level, income level, smoking status, drinking status, body mass index, and HBsAg status (Pfor trend<0.001). Subgroup analyses found that the association between TC levels and primary liver cancer was robust (all Pfor trend<0.05). The results didn't change significantly after exclusion of newly-diagnosed cases within the first 2 years, males with history of cirrhosis or subjects who took antihyperlipidemic drugs, participants with higher TC levels had a lower risk of primary liver cancer (all Pfor trend<0.05) and HR(95%CI) of incident primary liver cancer among participants with the highest quartile TC levels were 0.41 (0.28-0.61), 0.36 (0.25-0.53) and 0.38 (0.26-0.54), respectively. Conslusion: In this large prospective study, we found that baseline TC levels were inversely associated with primary liver cancer risk, and low TC level might increase the risk of primary liver cancer.

Abstract
Objective: To investigate the acceptance and attitude toward a novel fecal immunochemical test (FIT) in colorectal cancer screening among populations in China. Methods: From May 2018 to May 2019, 2 474 people aged 50-74 years were recruited from five provinces of China (Zhejiang, Anhui, Jiangsu, Hunan and Yunnan). The general demographic characteristics, acceptance of the new FIT technology and operational difficulties through the whole screening process were obtained through questionnaire survey. Multivariate logistic regression model was used to analyze the factors related to difficulties encountered in sampling stool, reading and uploading results. Results: The subjects were (60.0±6.4) years old, and female, high school of above educated, unemployed/retired/other, married and with medical insurance status of "new rural cooperative medical care (NRCMC)" accounted for 61.7% (1 526), 29.0%(718), 34.3% (849), 92.7% (2 293) and 31.3%(775), respectively. The population's acceptance of the FIT technology was 94.8%. In the process of FIT screening, the percentage of occurred difficulties in sampling stool, reading and uploading results were 33.1% (819), 46.4% (1 147) and 62.9% (1 557), respectively. The main difficulties were the uncertainty about whether the sampling operation was standard (28.0%), the inability to accurately judge the result displayed (32.5%) and the need for help without using a smartphone (44.2%). The results of multivariate logistic regression model analysis showed that people aged 65-74 years old and with medical insurance status of "NRCMC" were more likely to encounter difficulties in sampling, and those who were unemployed/retired/other and living with 3 or more family members were less likely to encounter difficulties in sampling. Those aged 65-74 years old, farmers or migrant workers, and those with "NRCMC" were more likely to encounter difficulties in readingresults, and those with 3 or more family members were less likely to encounter difficulties in reading result. Those with "NRCMC" were more likely to encounter difficulties in uploading results, and those with education level of high school or above, living with more than 3 family members were less likely to encounter difficulties in uploading results. Conclusion: The acceptance of the new FIT technology is relatively high among the subjects. Age, education level, occupation, number of family members living together and medical insurance status might be related to difficulties encountered in sampling stool, reading and uploading results, and it can be further strengthened in terms of the technology and characteristics of sub-populations.
