Abstract
Objective: To understand the species, distribution, and extent of drug resistance of pathogenic bacteria in patients with liver cirrhosis combined with bacterial infection in a tertiary hospital in Xinjiang. Methods: 1 271 cases with liver cirrhosis combined with infection were analyzed retrospectively for pathogenic bacterial species and drug resistance condition in different bacterial strain. Results: Among the 1 271 cases with liver cirrhosis, 480 were combined with infection, and the infection rate was 37.8%. The majority of infected patients had decompensated cirrhosis (438 cases). Peritoneum (327 cases, 60.8%) was the common infection site, followed by lungs (16.9%). 343 strains of pathogens were isolated from 480 infected cases, of which 289 strains were among the top 10 common distinct bacteria, accounting for 76.5% and 23.5% of Gram-negative and positive bacteria. The first top three strains were Escherichia coli. (33.2%), Klebsiella pneumoniae (11.4%), and Enterococcus faecium (11.1%), and there were differences in the drug resistance rates of each strain. Conclusion: In a tertiary hospital in Xinjiang, patients with decompensated cirrhosis have a high rate of bacterial infection. The pathogenic bacteria are diverse, mainly Gram-negative bacteria; however, the infection rate of Gram-positive bacteria such as Enterococcus is gradually increasing. Additionally, according to the bacterial properties, they are divided into four categories: Enterobacter, Enterococcus, glucose non-fermenting bacteria and Staphylococcus, and it is found that even the same species of bacteria have different drug resistance rates.

Abstract
Objective: To analyse the clinical characteristics and to explore the prognostic factors of acute pulmonary thromboembolism in the elderly. Methods: The medical records of inpatients with acute pulmonary thromboembolism discharged from Peking Union Medical College Hospital from January 1, 2012, to February 1, 2019 were retrospectively reviewed. The eligible patients were divided into elderly group (≥ 60 years old) and non-elderly group (<60 years old). The clinical symptoms, complications, laboratory results, pulmonary embolism severity index (PESI) and mortality were compared between the two groups. Mortality was further compared among elderly patients of different age groups. Cox regression analysis was used to analyze the risk factors of 7-day and 30-day death in elderly patients with pulmonary embolism. Results: A total of 503 patients with acute pulmonary embolism were included, including 279 cases in the elderly group and 224 cases in the non-elderly group. The incidence of cardiac arrest was higher in the elderly group compared with non-elderly group, while the incidence of chest pain and hemoptysis was less common in the elderly group. The proportions of comorbidities, including diabetes, hypertension, and coronary heart disease were higher in the elderly group while the proportion of autoimmune diseases was higher in the non-elderly group. In terms of prognosis, the PESI score and 7-day and 30-day mortality in the elderly group were higher than those in the non-elderly group. The mortality of elderly patients increased with age. Cox univariate regression analysis showed that infection, hypoalbuminemia, hypocalcemia, elevated cardiac troponin(cTnI), elevated N-terminal prohormone of brain natriuretic pepride(NT-proBNP) and PESI grade were associated with 30-day death. Multivariate Cox regression analysis showed that PESI grade and decreased serum calcium concentration were independent risk factors for 7-day death of pulmonary embolism in elderly patients. PESI grade, decreased serum calcium concentration and infection were independent risk factors for 30-day death. Conclusions: The mortality of elderly patients with pulmonary embolism was higher than that of non-elderly patients, and the mortality increased gradually with age. PESI grade, decreased serum calcium concentration and infection were independent risk factors for 30-day death of pulmonary embolism in elderly patients.

Abstract
Objective: To summarize the clinicopathological factors related to perinatal fetal death and to evaluate importance of fetal autopsy and placental pathology. Methods: The clinicopathological data of 105 perinatal fetal deaths in Beijing Haidian Maternal and Child Health Hospital from November 2012 to December 2020 were retrospectively analyzed. Relevant literature was also reviewed. Results: The maternal age of the deceased fetuses ranged from 22 to 43 years with the average (31.35±4.04 years), and the gestational weeks were 28-40+6 weeks. Among them, 101 were singleton cases and 4 twin cases. 103 fetuses died in uterus and 2 died during delivery. Relevant factors analysis of the 105 perinatal fetal deaths showed that 86 cases (81.9%, 86/105) were related to umbilical cord/placental abnormality, 10 cases (9.5%, 10/105) uterine infection, 6 cases (5.7%, 6/105) fetal factors, 1 case was fetal maternal blood transfusion syndrome, 1 case twin blood transfusion syndrome, and 1 case died of complete uterine rupture. Among the 86 cases related to umbilical cord/placental abnormality, the diagnosis was most often based on the gross examination of placenta. The most common cause of death was umbilical cord torsion with thin root, followed by placental abruption, tight umbilical cord winding, vascular rupture and umbilical cord true knot. The morphology of placenta revealed mainly functional changes. Among the 10 cases related to intrauterine infections, the placenta generally showed lobular placental edema. The morphological characteristics of ascending infection were mainly acute chorioamnionitis, and the morphological characteristics of blood-borne infection were mainly acute or chronic villitis, as well as villous interstitial inflammation. Identification of viral inclusions suggested viral etiology, while the final diagnosis was relied on laboratory testing. Among the 6 cases related to fetal abnormality, the diagnostic value of placenta was limited and the diagnosis could be made with fetal autopsy. Conclusion: The causes of perinatal fetal death are complex, diverse, and often the synergistic result of multiple factors. Fetal autopsy and placental pathology are the key technical means to identify the cause of death and deserve more attention and utilization.

Abstract
Objective: To detect the incidence and analyze the clinical significance of regions of homozygosity (ROH) through the single nucleotide polymorphism array (SNP array). Methods: The SNP array detection results of 5 116 pregnant women in the Third Affiliated Hospital of Guangzhou Medical University from January 2016 to December 2020 were retrospectively analyzed. The pregnant women with ROH (5 Mb as the threshold) were followed up to analyze the relationship between ROH and abnormal fetal phenotype. Whole exon sequencing was performed in 4 cases of consanguineous marriage to detect potential recessive causative genes in the ROH region. Results: (1) A total of 39 cases of ROH were detected, with a positive rate of 0.76% (39/5 116). Among them, 25 cases (64%, 25/39) were detected only on single chromosome, and chromosome 11 had the highest detection rate, suggesting the risk of uniparental disomy; fourteen cases (36%,14/39) were detected on multiple chromosomes, most commonly on chromosomes 11, 1, 3, 4 and 8. (2) The number of cases and detection rate of ROH detected by different prenatal diagnosis indicators were as follows: 12 cases (1.78%, 12/676) in pregnant women with abnormal non-invasive prenatal testing result, 12 cases (0.37%, 12/3 284) in pregnant women with ultrasound abnormality, 4 cases (4/4) in pregnant women with consanguineous marriage, 3 cases (0.92%, 3/326) in pregnant women with previous adverse pregnancy, 2 cases (1.15%, 2/174) in pregnant women with high risk of serology in screening, 2 cases (4.00%, 2/50) in pregnant women with abnormal fetal chromosomal karyotype, 2 cases (0.79%, 2/253) in pregnant women with advanced maternal age, 1 case (0.56%, 1/178) in pregnant women with related parental genetic factors and 1 case (0.58%, 1/171) in pregnant women with the other factors. (3) The follow-up results of 39 cases of prenatal ROH showed that there were 16 cases of term birth, 15 cases of termination of pregnancy, 2 cases of preterm births, 1 case of fetal death and 5 cases lost to follow-up. Conclusions: Chromosomal ROH phenomenon is not rare. By analyzing the detection rate of ROH in prenatal diagnosis, combined with the results of fetal phenotype and postpartum follow-up, the clinical characteristics of ROH are discussed, so as to better understand the relationship between ROH and its phenotype.

Abstract
Objective: To investigate the pathological characteristics of singleton placenta with abnormal shape and its influence on the outcome of maternal-fetal pregnancy. Methods: The clinicopathological data of singleton placentas with abnormal shape from January 2014 to December 2020 in the Department of Pathology, Haidian Maternal and Children Health Hospital were analyzed retrospectively. Results: There were 130 singleton placentas with abnormal shape in this cohort, including 48 succenturiate placentas, 12 bilobed placentas, 50 marginate placentas, 13 circumvallate placentas, 3 annular placentas, 2 membranous placentas and 2 fenestrated placentas. Gestational age ranged from 29+5 to 40+4 weeks. There were 51 cases of premature rupture of membranes, 11 cases of placenta previa, 5 cases of placental abruption, 15 cases of placental adhesion/implantation and 27 cases of postpartum hemorrhage. There were 46 preterm fetuses,28 fetuses with fetal growth restriction, 22 fetuses with intrauterine distress, and 1 fetus with intrauterine death. Grossly, the placental lobules of succenturiate placentas had apparent size difference, while two lobules of bilobate placenta were more consistent. The chorionic plate size was smaller than the bottom plate of circumvallate placenta, the folded fetal membrane in the rim of placenta was thickened (termed marginate placenta if there was no thickening). The membranous placenta was characterized by a thin, large membrane-like shape. Annular placenta showed characteristic hollow cylinder, ring or horseshoe-shape. Fenestrated placenta was characterized by tissue defects near central area. Microscopically, functional/morphologic changes were the main manifestations of inadequate maternal-fetal perfusion, including villous infarction, distal villous dysplasia and excessive villous maturation. Conclusions: The abnormal shaped singleton placentas showed variable extent of inadequate maternal-fetal perfusion, which may lead to adverse pregnancy outcomes such as premature delivery, fetal growth restriction, intrauterine distress or fetal death.

Abstract
Liposome-based immunoassay (LIA) is an attractive protocol for amplifying the detection signals because of the excellent ability of liposomes to encapsulate signal marker compounds. The antigen-binding activity of the conjugated antibodies on the liposomal surface is crucial for the specificity and sensitivity of LIA. We present here a general platform to ensure that antibodies can conjugate onto the surface of liposomes in a site-specific and oriented manner. A His-handle-modified antibody with Fc region-specific and covalent conjugation was first fabricated using a photoactivatable ZBpa-His tag that was engineered using the aminoacyl-tRNA synthetase/suppressor tRNA technique. Based on the high affinity between the His tag and divalent metal ions, the novel His-modified antibody was oriented onto the surface of nickel ion-modified liposomes encapsulating horseradish peroxidase. With the prostate-specific antigen as a model, the detection efficiency of the new immunoliposomes was evaluated by chemiluminescence immunoassay. The immunoliposomes exhibited a limit of detection of 0.2 pg mL-1, which was a six time improvement compared with that of the chemical-coupled antibody-liposome conjugates. Thus, the proposed immunoliposomes are expected to hold potential applications for the sensitive detection of various biomarkers in complicated serum samples.

Abstract
Objective: To analyze the current adherence to imatinib in patients with gastrointestinal stromal tumors (GIST) in China and its influencing factors. Methods: A cross-sectional survey was conducted. Study period: from October 1, 2020 to November 31, 2020. Study subjects: GIST patients taking imatinib who were diagnosed and treated in public tertiary level A general hospitals or oncology hospitals; those who had not been pathologically diagnosed, those who never received imatinib, or those who had taken imatinib in the past but stopped afterwards were excluded. The Questionnaire Star online surgery platform was used to design a questionnaire about the adherence to adjuvant imatinib therapy of Chinese GIST patients. The link of questionnaire was sent through WeChat. The questionnaire contained basic information of patients, medication status and Morisky Medication Adherence Scale. Results: A total of 2162 questionnaires from 31 provinces, autonomous regions, and municipalities were collected, of which 2005 were valid questionnaires, with an effective rate of 92.7%. The survey subjects included 1104 males and 901 females, with a median age of 56 (22-91) years old. Working status: 609 cases (30.4%) in the work unit, 729 cases (36.4%) of retirement, 667 cases of flexible employment or unemployment (33.3%). Education level: 477 cases (23.8%) with bachelor degree or above, 658 cases (32.8%) of high school, 782 cases (39.0%) of elementary or junior high school, 88 cases (4.4%) without education. Marital status: 1789 cases (89.2%) were married, 179 cases (8.9%) divorced or widowed, 37 cases (1.8%) unmarried. Two hundred and ninety-four patients (14.7%) had metastasis when they were first diagnosed, including 203 liver metastases, 52 peritoneal metastases, and 39 other metastases. One thousand eight hundred and sixty-nine patients underwent surgical treatment, of whom 1642 (81.9%) achieved complete resection. The median time of taking imatinib was 25 (1-200) months. Common adverse reactions of imatinib included 1701 cases (84.8%) of periorbital edema, 1031 cases (51.4%) of leukopenia, 948 cases (47.3%) of fatigue, 781 cases (39.0%) of nausea and vomiting, 709 cases (35.4%) of rash, and 670 cases (33.4%) of lower extremity edema. The score of the Morisky Medication Adherence Scale showed that 392 cases (19.6%) had poor adherence, 1023 cases (51.0%) had moderate adherence, and 590 cases (29.4%) had good adherence. Univariate analysis showed that gender, age, work status, economic income, residence, education level, marriage, the duration of taking medication and adverse reactions were associated with adherence to adjuvant imatinib therapy (all P<0.05). Multivariate analysis showed that female (OR=1.264, P=0.009), non-retirement (OR=1.454, P=0.001), monthly income ≤4000 yuan (OR=1.280, P=0.036), township residents (OR=1.332, P=0.005), unmarried or divorced or widowed (OR=1.362, P=0.026), the duration of imatinib medication >36 months (OR=1.478, P<0.001) and adverse reactions (OR=1.719, P=0.048) were independent risk factors for poor adherence to adjuvant imatinib. Among patients undergoing complete resection, 324 (19.7%) had poor adherence, 836 (50.9%) had moderate adherence, and 482 (29.4%) had good adherence. Meanwhile, 55 patients with good adherence (11.4%) developed recurrence after surgery, 121 patients with moderate adherence (14.5%) developed recurrence, 61 patients with poor adherence (18.8%) developed recurrence, and the difference was statistically significant (P=0.017). Conclusions: The adherence to adjuvant therapy with imatinib in Chinese GIST patients is relatively poor. Females, non-retirement, monthly income ≤4000 yuan, township residents, unmarried or divorced or widowed, the duration of imatinib medication >36 months, and adverse reactions are independently associated with poor adherence of GIST patients. Those with poor adherence have a higher risk of recurrence after surgery. Positive interventions based on the above risk factors are advocated to improve the prognosis of patients with GIST.

Abstract
A recent focus of quantum spin liquid (QSL) studies is how disorder/randomness in a QSL candidate affects its true magnetic ground state. The ultimate question is whether the QSL survives disorder or the disorder leads to a “spin-liquid-like” state, such as the proposed random-singlet (RS) state. Since disorder is a standard feature of most QSL candidates, this question represents a major challenge for QSL candidates. YbMgGaO4, a triangular lattice antiferromagnet with effective spin-1/2 Yb3+ions, is an ideal system to address this question, since it shows no long-range magnetic ordering with Mg/Ga site disorder. Despite the intensive study, it remains unresolved as to whether YbMgGaO4 is a QSL or in the RS state. Here, through ultralow-temperature thermal conductivity and magnetic torque measurements, plus specific heat and DC magnetization data, we observed a residual κ0/T term and series of quantum spin state transitions in the zero temperature limit for YbMgGaO4. These observations strongly suggest that a QSL state with itinerant excitations and quantum spin fluctuations survives disorder in YbMgGaO4. It remains an open question as to whether the quantum spin liquid state survives material disorder, or is replaced by some spin-liquid like state. Here, Rao et al succeed in resolving a resolving a κ0/T residual in the thermal conductivity of YbMgGaO4 strongly suggesting the survival of the quantum spin liquid state.

Abstract
Objective: To explore the method of predicting high lymph node load in patients with early breast cancer to avoid unnecessary sentinel lymph node biopsy. Methods: The clinicopathological and thoracic multi-slice spiral CT (MSCT) data of 2620 patients with early (cT1~2N0M0) breast cancer treated in the Affiliated Cancer Hospital of Zhengzhou University from January 1, 2014 to August 1, 2018 were collected. According to the postoperative pathological results, the patients were divided into the group with axillaryhigh lymph node burden (HNB) and the non-HNB group. The influencing factors of axillary lymph node burden in patients with early breast cancer were determined by univariate and multivariate analysis, and the diagnostic model of MSCT to HNB was established. The best cutoff value for the diagnosis of HNB was determined through analyzing the receiver operative characteristic (ROC) curve, and the consistency between MSCT diagnosis and pathological diagnosis was evaluated by Kappa test. Results: Among the 2 620 patients, 168 were diagnosed of HNB. Univariate analysis showed that the tumor size, the status of human epidermal growth factor receptor 2 (HER-2), the number of abnormal lymph nodes showed in MSCT, the ratio of the length to the diameter of the maximum abnormal lymph node as shown in MSCT, the condition of the maximum abnormal lymph node door, and the parenchyma of the maximum abnormal lymph node were related to axillary lymph node burden in patients with early breast cancer (P<0.05). Multivariate analysis showed that the number of abnormal lymph nodes showed in MSCT was an independent influencing factor of axillary HNB in patients with early breast cancer. Compared with patients without abnormal lymph nodes, the OR values of patients with 1, 2, 3 or more abnormal lymph nodes displayed by MSCT and in axillary HNB status were 3.305, 9.379, 126.163 and 780.953, respectively. Using 3 or more abnormal lymph nodes detected by MSCT to predict the area under the ROC curve of axillary HNB in patients with early breast cancer, the area was 0.928, the sensitivity was 82.1%, the specificity was 95.4%, and the accuracy was 94.5%. Kappa test showed that the consistency between MSCT diagnosis and pathological diagnosis was relatively high (Kappa=0.629, P<0.001). Conclusions: The number of abnormal lymph nodes showed in MSCT is an independent influencing factor of axillary HNB in patients with early breast cancer. Taking 3 or more abnormal lymph nodes showed in MSCT as the threshold can help to predict the axillary HNB status of early breast cancer patients and exempt some of them from unnecessary sentinel lymph node biopsy.

Abstract
Objective: To provide the risk stratification method of hepatoblastoma (HB) suitable for implementation in China and explore the new treatment method for high-risk HB patients. Methods: A total of 100 cases of children and adolescents under 18 years old with newly diagnosed HB in Sun Yat-sen University Cancer Center and Sun Yat-sen University First Affiliated Hospital from September 2014 to September 2018 were included. According to the clinical stage, AFP level, pathological subtype and other factors, patients were stratified into four groups: extremely low-, low-, intermediate- and high-risk. The patients at very low risk were treated with surgery only and followed-up. The patients at very low risk were treated with C5V(Cisplatin+ 5-Fluroracil+ Vincristine) regimen for 4 courses. The patients at intermediate risk were treated with C5VD(Cisplatin+ 5-Fluroracil+ Vincristine+ Doxorubicin)regimen before and after surgery for 6-8 courses. The patients at high risk were treated with C5VD and IIV (ifoshamide+ irinotecan+ vincristine) alternately before and after surgery for 8 courses. Results: One hundred patients were stratified into extremely low-risk, low-risk, medium-risk and high-risk groups for 2, 10, 51 and 37 cases, respectively. Eighty three cases had evaluable lesions before chemotherapy. Among them, 65 patients achieved partial remission, stable disease and progressive disease were observed in 10, and 8 cases, respectively, with a response rate of 78.3%. During a median follow-up of 20 months, 30 patients experienced tumor relapse or progression, and 27 of them died. The 2-years progression-free survival (PFS) and overall survival (OS) rates were 69.2% and 72.0%, respectively. The 2-years PFS rates of patients with extremely low risk, low risk, medium risk and high risk were 100%, 88.9%, 75.3% and 43.2%, respectively. The 2-years OS rates were 100%, 100%, 81.0% and 44.8%, respectively. Conclusions: The novel HB risk classification is simple and feasible. With active comprehensive treatment, patients at extremely low-, low- and medium-risk have excellent outcomes. The survival rate of high-risk HB patients remains to be improved, and new treatment strategies need to be explored.

Abstract
Objective: To analyze the clinical characteristics of infantile Takayasu arteritis and the efficacy of infliximab (IFX). Methods: Clinical manifestations, laboratory investigations and infliximab intervention of a case with infantile Takayasu arteritis, who was admitted to Department of Rheumatism and Immunology, Children's Hospital, Capital Institute of Pediatrics in January 2018, were reviewed and analyzed. The related literature published from the beginning to March 2020 were retrieved from CNKI, Wanfang, SinoMed and PubMed with the keywords of"Takayasu arteritis","Infant" in both Chinese and English. Results: This case was a 70-day-old boy admitted due to recurrent fever for 20 days. On admission, his blood pressure were 104/90, 95/59, 125/80, and 152/125 mmHg (1 mmHg=0.133 kPa) in the right arm, left arm, right leg, and left leg, respectively. The complete blood cell count showed leukocytosis (22.6×109/L), thrombocytosis (858×109/L) and mild anemia (80 g/L). He also had elevated erythrocyte sedimentation rate (119 mm/1h), serum ferritin (598 μg/L) and C-reactive protein (112 mg/L). Computed tomographic angiography (CTA) showed narrowing of the thoracic and abdominal aorta, with thickening and heterogenous enhancement of the vessel wall. Coronary artery ultrasound detected dilatation and wall thickening of the bilateral coronary arteries, and uneven dilatation of the middle segment of the right coronary artery, showing bead-like change. Vessel wall thickening was also found in the other main arteries, including both femoral arteries, axillary arteries, carotid arteries, and subclavian arteries, and both superficial femoral arteries were slightly narrowed in the distal segments. The diagnosis of TA was confirmed, and the boy was treated with infliximab monotherapy (5 mg/(kg·every time), a total of 13 times). Then his body temperature and all inflammatory markers were normalized, and the vascular pathology was resolved according to the radiography. No side effects such as allergy or infection were noted during the treatment. During the 2 years and 6 months of follow-up, the boy maintained normal growth and development. Literature review found 8 related articles, and one of them was in Chinese but had limited information. In the other 7 papers, a total of 7 infants with TA were reported. The most common symptom was fever (5 cases), and inflammatory markers usually elevated, and the most common affected artery was abdominal aorta (6 cases). Most cases were treated with glucocorticoid. Conclusions: TA is a rare disease in infants, usually presents with fever and increased inflammatory markers. At the early stage, infliximab monotherapy could effectively control the symptoms and ensure normal growth and development.

Abstract
Protein phosphatase 4 (PPP4) is a protein phosphatase that, although highly expressed in the testis, currently has an unclear physiological role in this tissue. Here, we show that deletion of PPP4 catalytic subunit gene Ppp4c in the mouse causes male-specific infertility. Loss of PPP4C, when assessed by light microscopy, did not obviously affect many aspects of the morphology of spermatogenesis, including acrosome formation, nuclear condensation and elongation, mitochondrial sheaths arrangement and '9 + 2' flagellar structure assembly. However, the PPP4C mutant had sperm tail bending defects (head-bent-back), low sperm count, poor sperm motility and had cytoplasmic remnants attached to the middle piece of the tail. The cytoplasmic remnants were further investigated by transmission electron microscopy to reveal that a defect in cytoplasm removal appeared to play a significant role in the observed spermiogenesis failure and resulting male infertility. A lack of PPP4 during spermatogenesis causes defects that are reminiscent of oligoasthenoteratospermia (OAT), which is a common cause of male infertility in humans. Like the lack of functional PPP4 in the mouse model, OAT is characterized by abnormal sperm morphology, low sperm count and poor sperm motility. Although the causes of OAT are probably heterogeneous, including mutation of various genes and environmentally induced defects, the detailed molecular mechanism(s) has remained unclear. Our discovery that the PPP4C-deficient mouse model shares features with human OAT might offer a useful model for further studies of this currently poorly understood disorder.

Abstract
Objective: To investigate the clinical characteristics and related factors of acute tubular necrosis (ATN) in patients with minimal change disease (MCD). Methods: Patients from Chinese PLA General Hospital who were pathologically diagnosed with MCD and had clinical manifestations of nephrotic syndrome from January 1, 2013 to December 31, 2019 were included. The clinical and pathological data of patients were retrospectively analyzed. Meanwhile, the incidence and clinical characteristics of ATN in different age groups were compared. The risk factors for ATN were assessed using binary logistic regression. Results: A total of 525 patients were included, with a gender ratio of 1.56∶1 (male: female), aged 33 (21, 48) years old. ATN occurred in 49 (9.3%) of 525 patients, of which 34 were male and 15 were female. The incidence of ATN increased with age in MCD patients of different age groups (χ(2)=31.442, P<0.001). The incidence of ATN in groups of age≤20 years, 21-40 years, 41-60 years, and >60 years was 2.4% (3/123), 5.2% (10/192), 13.2% (20/152) and 27.6% (16/58), respectively. Elevations of alanine aminotransferase (ALT), aspartate aminotransferase (AST), γ-glutamyl transpeptidase (GGT) and serum IgE occurred in 92 patients (17.5%), 53 patients (10.1%), 99 patients (18.9%), and 303 patients (57.7%), respectively. There were significant differences in age, ALT, serum creatinine, serum urea nitrogen, history of diabetes and history of hypertension between non-ATN group and ATN group (all P<0.05). The results of logistic regression analysis showed that>40 years old (OR=6.283, 95% CI: 2.695-14.649, P<0.001) and serum albumin (OR=0.924, 95% CI: 0.857-0.997, P=0.040) was independently associated with ATN in MCD patients. Conclusion: Age>40 years is an independent risk factor and serum albumin is a protective factor for ATN in MCD patients.

Abstract
Objective: Platelet-derived growth factor α (PDGFRA)-mutant gastrointestinal stromal tumor (GIST) is a relatively rare disease, whose clinicopathological characteristics and prognosis have been poorly studied. In this paper, the clinicopathological features and prognostic factors of PDGFRA-mutant GIST are investigated to provide more data for its understanding and treatment. Methods: A retrospective case-control study was used to collect the medical records of patients with GIST who underwent surgical resection in Zhongshan Hospital of Fudan University from January 2015 to August 2019. Patients with PDGFRA-mutant GIST were enrolled, and those with synonymous PDGFRA mutations, non-tumor-related deaths, and lack of clinicopathological data were excluded. The clinicopathological data were collected and the risk factors associated with prognosis were analyzed. Results: Among the enrolled 59 patients, there were 41 males (69.5%) and 18 females (30.5%) with the median age of 60 (25-79) years. All tumors originated from the stomach. The tumor size was 5 (3-7) cm, and the mitotic count was 2 (1-4)/50 high-power fields (HPF). According to the modified NIH risk stratification, 8 cases were classified as very low risk (13.6%), 25 cases as low risk (42.4%), 14 cases as moderate risk (23.7%), and 12 cases as high risk (20.3%). There were 7 cases of exon 12 mutation and 52 cases of exon 18 mutation (including 36 cases of D842V mutation). A comparison of clinicopathological features between the D842V mutation group and the non-D842V mutation group showed no statistically significant difference (all P>0.05). During a median follow-up of 21 (0-59) months, the 1- and 3-year relapse-free survival (RFS) rates of all the patients were 96.6% and 91.5%, respectively. There were 8 cases of recurrence and 3 cases of death. Six GIST patients with D842V mutation had tumor recurrence after operation, of whom 4 cases achieved varying degrees of tumor remission after being treated with dasatinib or avapritinib. Log-rank analysis showed that the overall survival (OS) of male was better than that of female (100% vs. 83.3%, P=0.046), but there was no significant difference in OS among patients with different risk grades (P=0.057). The RFS and OS of patients with D842V mutation and non-D842V mutation, exon 12 and exon 18 mutation were similar (all P>0.05). Univariate Cox analysis showed that RFS was associated with gender (P=0.010), tumor size (P=0.042), mitotic count (P=0.003), and the modified NIH risk stratification (P=0.042), while multivariate analysis revealed that higher risk grade was an independent risk factor for recurrence of PDGFRA-mutant GIST (HR=12.796, 95%CI: 1.326-123.501, P=0.028). Gender was an independent factor for recurrence, and the risk of recurrence in males was lower than that in females (HR=0.154, 95%CI: 0.028-0.841, P=0.031). Conclusions: Gender and the modified NIH risk stratification are independent risk factors for recurrence of PDGFRA-mutant GIST, while patients with D842V and non-D842V mutation, and exon 12 and exon 18 mutation have a similar risk of recurrence and death.

Abstract
Objective: To summarize the efficiency and long-term outcomes of limited-stage Hodgkin lymphoma in children and adolescents with ABVD therapy and determined whether omitting radiotherapy for a low-risk patient enabled the achievement of complete response (CR) after chemotherapy. Methods: We retrospectively analyzed data from 13 y (2004-2016) from patients aged ≤18 y with limited-stage HL admitted to the Sun Yat-sen University Cancer Center. Patients received treatment with ABVD chemotherapy alone or ABVD chemotherapy followed by low-dose involved field radiotherapy. Results: Total 85 subjects were eligible for study inclusion; the median age was 12 (3-18) y; 66 (77.6%) were men, 80 (94.1%) had stage-II disease, 56 (65.9%) were at low-risk, and the median follow-up duration was 72 (8-196) months; 12 relapsed, 2 had secondary neoplasm, and 2 died. The 5-year event free survival (EFS) was (85.6±3.8) %, and the overall survival (OS) was 100%. The 5-year EFS and OS was (89.1±4.2) % and 100%, respectively, for the low-risk cohort and (79.3±7.5) % and 100%, respectively for the intermediate-risk cohort. Among the 39 low-risk patients who achieved CR after chemotherapy, 15 received treatment with chemotherapy followed by LD-IFRT. In the exploratory subset analysis, the low-risk cohort who achieved CR after chemotherapy, the 5-year EFS for comparing ABVD alone with chemotherapy followed by LD-IFRT was (87.0±7.0) % versus 100% (P=0.506) , and the OS was 100% for both the groups. Conclusions: Our retrospective analysis showed excellent survival of limited-stage HL patients with ABVD therapy. For patients who achieving CR after chemotherapy with low-risk HL, received chemotherapy followed by LD-IFRT does not improve 5-year OS and EFS. The use of risk- and response-based stratification may facilitate the development of effective and less toxic protocols.

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 investigate the clinical features and prognosis of interstitial lung disease patients with positive anti-neutrophil cytoplasmic antibody. Methods: The patients with interstitial lung disease who visited Peking Union Medical College Hospital from March 2006 to March 2016 were divided into three groups: interstitial lung disease with ANCA-positive(ANCA-ILD), connective tissue disease associated interstitial lung disease and interstitial pneumonia with autoimmune features (CTD-ILD/IPAF) and idiopathic interstitial pneumonia (IIP). The three groups were analyzed in terms of clinical manifestations, serology, lung function, imaging, survival and recurrence. Results: Two hundred and seventy four patients were enrolled and 38 (14%) were ANCA-positive of whom 16 were male and 22 were female. The age of 38 ANCA-positive patients was (59±10) years and the follow-up time was (52±31) months. Seven among the 38 ANCA-positive patients died and the death rate is 18.42%. The ANCA-positive patients with interstitial lung disease have higher onset age (ANCA-ILD:59±10,CTD-ILD/IPAF:52±10,IIP:53±11,H=19.29, P<0.001), lower hemoglobin (ANCA-ILD: 129±21, CTD-ILD/IPAF: 138±15, IIP: 140±19, H=8.17, P=0.017), higher erythrocyte sedimentation rate (ANCA-ILD:45±35, CTD-ILD/IPAF:26±24,IIP:19±22,H=19.73, P<0.001), lower lung function improvement rate after treatment (ANCA-ILD:31%,CTD-ILD/IPAF:59%,IIP: 39%,χ(2)=11.74,P=0.003), lower absorption rate of CT lesion (ANCA-ILD:61%,CTD-ILD/IPAF:82%,IIP:67%, χ(2)=9.23,P=0.010) and higher death rate(ANCA-ILD:18%,CTD-ILD/IPAF:6%,IIP:12%, χ(2)=7.16,P=0.028). Conclusions: There are significant differences in clinical characteristics between ANCA-positive patients and other types of pulmonary interstitial disease. And both the treatment effect and the prognosis is poor for the ANCA-positive patients.

Abstract
OBJECTIVE The optimal treatment for gastrointestinal stromal tumor (GIST) of the rectum is controversial due to the extremely low incidence of the disease. The aim of the present study was to compare the clinical outcomes of different treatment modalities for rectal GIST by reviewing the 14-year experience in our center. METHOD Medical records of rectal GIST patients who received surgical treatment in our center between January 2004 to December 2017 were reviewed retrospectively. Overall survival (OS) and recurrence-free survival (RFS) were used as the observation endpoints. RESULTS Included in this study were 71 GIST patients, including 42 patients who underwent local excision (LE) and 29 patients who underwent segmental resection (SR). There were differences in tumor size (P = 0.001) and malignant risk grade (P = 0.007). The LE approach achieved a lower rate of R0 resection than SR (29/42 vs.27/29, P = 0.015) and shorter hospital stay (P = 0.004). Preoperative imatinib mesylate (IM) therapy improved the rate of sphincter-sparing surgery for patients with tumors in the very low segment of the rectum (P = 0.012) and offered better R0 resection margins (P = 0.027). Multivariate analysis showed that the resection margin status (P = 0.014), risk stratification (P = 0.001) and IM therapy (P = 0.042) were independent factors affecting RFS of rectal GIST patients but not the surgical modalities (LE vs. SR, P = 0.802). Multivariate analysis showed no significant impact of these variables on OS. CONCLUSION Selection of surgical modalities has no significant impact on the prognosis. Local excision is the preferred surgical modality for resectable rectal GIST by virtue of less injury and shorter hospital stay. IM therapy has proved to be associated with improved RFS for rectal GIST patients.

METHODS All echinococcosis cases reported in Yixing City since 2007 that were captured from the China National Notifiable Infectious Disease Reporting Information System of Chinese Center for Disease Control and Prevention received a case study, and serological test and transabdominal B-mode ultrasound screening were performed among permanent residents and mutton market workers in Fangdong and Fangzhuang villages of Yixing City from 2011 to 2018. The cyst, mass and tubercle were detected in the liver and lung of the sheep from the mutton markets, and the Echinococcus coproantigen was detected in the canine stool samples from Fangdong and Fangzhuang villages. In addition, the awareness of echinococcosis prevention and control knowledge was investigated in the two villages using a questionnaire survey from 2011 to 2018. RESULTS A total of 7 cases with echinococcosis had been reported in Yixing City since 2007, with prevalence of 0.56/100 000, and all cases were E. granulosus-infected patients, including 2 cases with a history to travel to echinococcosis-endemic areas and 5 cases with a history of working in local mutton markets or dog contacts. From 2011 to 2018, a total of 1 861 residents received serological tests, with 0.54% seropositivity, and no seropositives were detected since 2016. Among the 1 807 individuals receiving transabdominal B-mode ultrasound screening, suspected cysts were found in 143 individuals (7.91%), and 1.40% (2/143) seropositivity was detected in these individuals. The mean positive rate of the Echinococcus coproantigen was 0.67% (3 /446) in the canine stool samples. Among the 4 010 sheep liver and lung specimens sampled from the mutton markets, 7 specimens (0.17%) were detected with cysts or tubercles. In addition, the mean awareness rate of echinococcosis prevention and control knowledge was 76.95% among the 538 subjects receiving questionnaire surveys from 2011 to 2018, and the overall awareness appeared a tendency towards a rise year after year. CONCLUSIONS Although the prevalence of echinococcosis and the seropositivity of anti-Echinococcus antibodies are low, there is still a risk of transmission of echinococcosis in Yixing City. The surveillance of echinococcosis should continue to be intensified and related control interventions are required.

Abstract
Personalized medicine requires the integration and processing of vast amounts of data. Here, we propose a solution to this challenge that is based on constructing Digital Twins. These are high-resolution models of individual patients that are computationally treated with thousands of drugs to find the drug that is optimal for the patient.

Abstract
The pathogenicity of the shrew-borne Imjin virus (MJNV) is unknown. The objective of our study was to find serological evidence of MJNV infection in humans. Partial MJNV nucleocapsid protein (NP) was cloned and expressed as an antigen for double-antigen sandwich ELISA, IgM capture ELISA, and dot blot to detect MJNV specific antibodies in hemorrhagic fever with renal syndrome (HFRS) patients’ and healthy persons’ sera from endemic areas in China. The purified recombinant NP reacted with neither the 90 healthy individuals’ sera from non-endemic areas of MJNV nor the 100 antisera to HFRS-causing virus, indicating that the MJNV NP had no cross-reaction with normal human sera and HFRS-causing viral antibodies. As determined by screening ELISA and dot blot analysis, IgG antibodies against MJNV NP were detected in sera from two of 385 healthy individuals from MJNV-endemic areas, suggesting infection with MJNV or MJNV-like thottimvirus. Based on the suggestive evidence, healthcare workers should be alert to febrile diseases occurring among individuals with exposure to shrew-infested habitats.

Abstract
Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumors in the gastrointestinal tract. Though surgical resection is the only radical treatment, postoperative recurrence and metastasis often occur. The first-line therapy for the treatment of recurrent, metastatic and unresectable GIST is imatinib. More than 80% of patients can benefit from imatinib treatment, but half of patients will still have recurrence or metastasis within 2 years after treatment initiation, and secondary drug resistance is a major cause of disease progression. Therefore, adeep understanding of the mechanisms of secondary drug resistance will guide us to develop personalized therapeutic schedule in the future. This article describes the mechanism of IM secondary resistance from the aspects of gene alteration, abnormal activation of signal transduction pathway, autophagy, apoptosis and drug concentration. It is found that single drug therapy has certain limitations in patients with secondary resistance to IM. Using IM combined with downstream signaling molecule inhibitors, autophagy inhibitors, insulin-like growth factor 1 receptor (IGF-1R) inhibitors, heat shock protein 90 (HSP90) inhibitors, cytotoxic T lymphocyte - associated antigen - 4 (CTLA - 4) antibodies and mitochondrial inhibitors provide us new therapeutic ideas. However, these combination treatments are still in the research phase, and further trials are needed to confirm the safety and efficacy. With the gradual deepening of research on drug resistance mechanisms, it will provide more solutions to the current serious drug resistance problem.

Abstract
Peroxisome proliferator activated receptor delta (PPARD) is a nuclear receptor transcription factor whose single nucleotide polymorphism (SNP), especially PPARD-87 T>C (rs2016520), may play an important role in expression regulation of PPARD. But its expression patterns as well as contribution in colorectal cancer (CRC) are still controversial. In this study, whether the intratumoral heterogeneity of polymorphism of PPARD-87 T>C (rs2016520) existed and its influence in CRC were investigated. Tumor masses from primary CRC patients were collected during the operation of tumorectomy, specimens at the different sites of the same tumor mass were sampled and stored individually. The SNP of PPARD-87 T>C was detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), and the expression of PPARD in vivo was observed by immunohistochemistry. The correlation of PPARD -87 T>C intratumoral polymorphism and the clinicopathological parameters of patients was analyzed statistically. Tumor samples were collected from 106 CRC patients (70 males and 36 females) with an average age of 61.04±13.67 years. A total number of 808 samples (7.60±1.60 per patient) were mainly harvested at peripheral superficial (n=376), central superficial (n=163), invasive front (n=112) and mesenteric cancer foci (n=42) of tumor tissues as well as cancerous adjacent mucosa (n=104). PCR-RFLP analysis showed that T/T (n=460, 56.9%) and T/C (n=334, 41.3%) were the main genotypes of -87 T>C among these samples. Furthermore, intratumoral genotype of -87 T>C was homogeneous in 90 patients and heterogeneous in other 16 patients. The intratumoral heterogeneity was related to patients' age (P=0.016), tumor location (P=0.011) and the grade of differentiation (P=0.022). For patients with intratumoral heterogeneity, immunochemistry showed the expressions of PPARD were not influenced by T/T or T/C genotypes. Intratumoral heterogeneity of PPARD-87 T>C wildly existed in CRC, and associated with patients' age, tumor location and differentiation. However, the immunochemistry assay revealed that there's no significant link between heterogeneity and expression of PPARD.

Abstract
Chronic rhinosinusitis with nasal polyps (CRSwNP) is one of the common diseases. Involving the nasal passages and nasal passages, it may affect 10% of the global population. Surgical intervention is usually required. Its pathogenesis is a multielement and multistep complex process. Current multi-factor hypothesisplays a dominant role in the etiology of nasal polyps (NP). Infectious factors always play an important role in the pathogenesis of CRSwNP. The lesions of nasal polyp have different inflammatory cell infiltration and can be divided into two types in immunophenotpe: the first is characterized by Th2 cell reaction and marked eosinophil infiltration,and the second is Th1/Th17 cell response and non-eosinophil infiltration are characteristic.NP, which is mainly infiltrated by neutrophils, is more and more common in China. B cell activation factor (BAFF) is a major inflammatory factor related to the regulation of B cell activation.Recent experiments have shown that BAFF is also high in nasal polyps.In this paper, the effects and interactions of BAFF and eosinophils and neutrophils in CRSwNP were reviewed.

Abstract
Magnetism of Cu2(OH)3Br single crystals based on a triangular lattice is studied by means of magnetic susceptibility, pulsed-field magnetization, and specific heat measurements. There are two inequivalent Cu2+ sites in an asymmetric unit. Both Cu2+ sublattices undergo a long-range antiferromagnetic (AFM) order at [Formula: see text] K. Upon cooling, an anisotropy crossover from Heisenberg to XY behavior is observed below 7.5 K from the anisotropic magnetic susceptibility. The magnetic field applied within the XY plane induces a spin-flop transition of Cu2+ ions between 4.9 T and 5.3 T. With further increasing fields, the magnetic moment is gradually increased but is only about half of the saturation of a Cu2+ ion even in 30 T. The individual reorientation of the inequivalent Cu2+ spins under field is proposed to account for the magnetization behavior. The observed spin-flop transition is likely related to one Cu site, and the AFM coupling among the rest Cu spins is so strong that the 30 T field cannot overcome the anisotropy. The temperature dependence of the magnetic specific heat, which is well described by a sum of two gapped AFM contributions, is a further support for the proposed scenario.

Abstract
Objective: To determine the association of serum fibroblast growth factor-23 concentrations with age-related cardiac diastolic function subclinical state and whether this association differs by sex. Methods: Seven hundred sixteen healthy subjects (aged 35-89 years, 68.4% female) were selected from National Basic Research Program of China (973 Program-China Medical University subsection) between January 2014 and February 2015 and assigned into 4 groups according to sex and age:< 60 years old male and female group, ≥ 60 years old male and female group. Blood biochemical indicators and general clinical data of the subjects were measured. The glomerular filtration rate (eGFR) were estimated using the Modified Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI-ASIA) equation. The fibroblast factor 23 (FGF-23), C-reactive protein (CRP) and interleukin-6 (IL-6) were measured by enzyme-linked immunosorbent assay (ELISA). Cardiac structure and function parameters including left atrial diameter (LAD), inter-ventricular septum thickness (IVST), left ventricle posterior wall thickness (LVPWT), left ventricle mass index (LVMI),left atrial mass index (LAVI) and the ratio of peak velocity of early filling to the septal early peak diastolic mitral annulus velocity(E/e') were measured by echocardiography. Association between serum FGF-23 and aging-related diastolic function subclinical status was analyzed by binary Logistic regression analysis. Results: (1) Serum log-transformed FGF-23 levels were significantly higher in males than in females [(2.0±0.3) ng/L vs (1.9±0.4) ng/L, P<0.05]. (2) Cardiac diastolic function gradually decreased with age, and age related cardiac diastolic function decline of female was significantly higher than males[E/e':<60 years old male group (7.6±2.6), ≥ 60 years old male group (8.6±2.7), P<0.01;<60 years old female group (8.3±2.3), ≥ 60 years old female group (9.5±3.1), P<0.01; LAVI:<60 years old female group (14±5) ml/m(2), ≥ 60 years old female group (16±5) ml/m(2), P<0.01]. (3) Serum FGF-23 was significantly positively correlated with age (r=0.089, P<0.05) and LAVI (r=0.084, P<0.05) in total study population while with E/e' (r=0.149, P<0.05) only in males. There was no significant correlation between serum FGF-23 and cardiac diastolic function parameters in females. (4) Binary Logistic regression analysis showed that median and high FGF-23 were independently associated with age-related cardiac diastolic function decline (OR=2.831, 95% CI: 1.144-7.009, P=0.024; OR=2.548, 95% CI: 1.053-6.163, P=0.038) in males. Conclusions: Serum FGF-23 concentrations are associated with age-related cardiac diastolic function subclinical state in a healthy Chinese population. High levels of FGF-23 are independently associated with age-related cardiac diastolic function decline in males.

Abstract
Objective: To summarize the clinical manifestations and determine the molecular etiology for two collagen type Ⅵ-related myopathy pedigrees. Methods: Two spontaneous collagen type Ⅵ-related myopathy patients were admitted to Department of Neurology, Children's Hospital, Capital Institute of Pediatrics in October 2017. Clinical data of probands and their family members were collected and their genomic DNA was obtained for genetic testing. Next generation sequencing was performed and the variants were verified by the Sanger sequencing in the family members. Results: Target region sequencing indicated that the proband of family 1 has carried a heterozygous variant of COL6A3 gene, c.6229G>C(p.Gly2077Arg), and it was de novo variant confirmed by Sanger-sequencing in the family.The patient 1, a 2-year-three-month old boy, was admitted due to motor retardation at birth. He was defined as early severe Ullrich congenital muscular dystrophy. He never achieved independent ambulation, he had onset of symptoms was found at birth, including diffuse muscle weakness, striking distal joint hyperlaxity, proximal contractures, calcaneal protrusion, kyphosis, and hip dislocation. Serum CK level was elevated slightly and EMG showed neurogenic changes. The patient 2, a 7-year-old girl with a limp for 4 years, carried one de novo variant of COL6A3 gene,c.5169_5177del (p.Glu1724_Leu1726del). This variant results in the deletion of amino acids (1724 to 1726) in α3 chain of collagen Ⅵ, which may disturb the function of this protein.She was diagnosed as Bethlem myopathy with a mild phenotype. She had delayed motor milestones and presented with walking on tiptoe, hypotonia, and ithylordosis. The contracture of proximal joints was not very obvious. Serum CK level was normal and EMG showed myogenic changes.Muscle biopsy revealed muscular dystrophy and muscle magnetic resonance imaging of patient 2 showed vastus lateral is a "sandwich" sign. Immunofluorescence staining for COL6A3 chain in the cultured skin fibroblasts from patients 2 showed decreased deposition compared with control. Conclusions: These two patients were diagnosed as spontaneous collagen type Ⅵ-related myopathy and carried different variants of COL6A3 gene. Different in pathogenetic variants could cause different genetic features and different phenotypes. Collagen type Ⅵ- related myopathy patients have various clinical manifestations. Typical phenotypes include muscular dystrophies, proximal contractures, and distal hyperlaxity. Muscle MRI shows diffuse fatty infiltration of gluteus maximus and thigh muscle. The histological staining showed the low level expression of COL6A3 chain. The seventy of phenotype was related to the genotype.

Abstract
Objective: To investigate the relationship between expression of programmed cell death ligand-1(PD-L1) in the tissue of neuroblastoma (NB) and patient's clinical characteristics and prognosis. Methods: Clinical data and surgical tissue paraffin blocks of 100 newly diagnosed NB children at Sun Yat-sen University Cancer Center between January 2000 and December 2015 were collected and the expression level of PD-L1 and its' relationship with pathological parameters and survival rate were analyzed retrospectively. The ratio between groups was compared by chi-square test. Kaplan-Meier method was used for survival analysis and COX regression model was used for multivariate analysis. Results: Among 100 cases, 71 were males and 29 females; there were 5 cases of stageⅠ, 4 cases of stageⅡ, 19 cases of stage Ⅲ, 65 cases of stage Ⅳ and 7 cases of stage Ⅳs. Ten out of 62 cases (16%) were N-MYC amplified; 15 cases were in low-risk group, 18 were in medium-risk group and 67 were in high-risk group. The positive rate of PD-L1 in NB tumor tissue was 57% (57/100), of which 55 were weakly positive, 1 was moderately positive and 1 was strongly positive. The positive rates of PD-L1 expression in tumor tissues without bone metastasis were higher than those with bone metastasis(66%(39/59)vs.44%(18/41), χ(2)=4.864, P=0.027), the positive rates of PD-L1 expression in tumor tissues pathologically diagnosed as neuroblastoma were higher than those pathologically diagnosed as ganglioneuroblastoma (61%(53/87) vs.31%(4/13), χ(2)=4.195, P=0.041), the positive rates of PD-L1 expression in tumor tissues originated from abdominal cavity were higher than those originated from other places (61% (51/83)vs.35%(6/17), χ(2)=3.937,P=0.047).The 4-year event-free survival (EFS) rates of patients with PD-L1 negative and positive were 40% and 33% (χ(2)=0.009, P=0.923), respectively. The 4-year overall survival (OS) rates of patients with PD-L1 negative and positive were 62% and 58% (χ(2)=0.294, P=0.587). Among 33 non-high-risk patients, the 4-year EFS rates of patients with PD-L1 negative and positive were 89% and 78% (χ(2)=0.001, P=0.965), the 4-year OS rates of patients with PD-L1 negative and positive were 100% and 96% (χ(2)=0.500, P=0.480). Among 67 high-risk patients, the 4-year EFS rates of patients with PD-L1 negative and positive were 24% and 11% (χ(2)=1.154, P=0.282), the 4-year OS rates of patients with PD-L1 negative and positive were 48% and 41% (χ(2)=0.692, P=0.405). Multivariate analysis showed that N-MYC gene amplification was an independent adverse prognostic factor for OS and EFS rates of NB patients (RR: 1.726,95%CI:1.209-2.466; RR:1.326,95%CI:1.014-1.736) and advanced clinical stage was an independent adverse prognostic factor for EFS rates of NB patients (RR: 26.498, 95%CI:3.518-199.614). Conclusions: The expression of PD-L1 in NB tumor tissues was correlated with the clinical characteristics of children. However, there were no significant differences in the prognosis of patients with or without PD-L1 expression.

Abstract
BACKGROUND This study was designed to evaluate the efficiency and tolerability of empagliflozin (EMPA) as monotherapy or add-on to existing therapy in patients with type 2 diabetes mellitus (T2DM). METHODS Randomized controlled trials (RCTs) comparing efficacy and safety of EMPA vs placebo or EMPA plus other antidiabetes drugs vs placebo plus other oral antidiabetes drugs (OADs) in T2DM were recruited from electronic database Pubmed, Web of Knowledge, and Cochrane Central Register of Controlled Trials (CENTRAL), supplemented by a hand search of the reference lists of selected articles. Main effect sizes were change from baseline on glycemia control, body weight, blood pressure, and complications (i.e., incidence of urinary and genital tract infections, and morbidity of hypoglycemia and hyperglycemia). Random-effects model was used to account for clinical or methodologic heterogeneity across studies. RESULTS Fifteen RCTs with a total number of 7891 individuals (5374 in EMPA group and 2517 in control group) were suitable for this meta-analysis. The results demonstrated that significant improvements in glycemia control, body weight, and blood pressure were associated with EMPA application (i.e., monotherapy and add-on therapy) in patient with T2DM when compared with placebo. Meanwhile, EMPA 10 and 20 mg improved glycemia, body weight, and blood pressure control for patients with T2DM. There was no significant difference in incidence of hypoglycemia and urinary tract infections across EMPA and placebo group. Significant reduced risk of hyperglycemia was revealed in EMPA group vs placebo (risk ratio: 0.34, 95%confidence interval: 0.23-0.49, P < .00001), except in patients on background insulin therapy. However, increased risk of genital infection was noted across EMPA vs placebo (risk ratio: 2.59, 95% confidence interval: 1.80-3.71, P < .00001). CONCLUSION Our evidence supports the application of EMPA in treatment of patients with T2DM who are obesity or at risk of weight gain.

Abstract
We present measurements on a series of materials, Li_{2}In_{1-x}Sc_{x}Mo_{3}O_{8}, that can be described as a 1/6th-filled breathing kagome lattice. Substituting Sc for In generates chemical pressure which alters the breathing parameter nonmonotonically. Muon spin rotation experiments show that this chemical pressure tunes the system from antiferromagnetic long range order to a quantum spin liquid phase. A strong correlation with the breathing parameter implies that it is the dominant parameter controlling the level of magnetic frustration, with increased kagome symmetry generating the quantum spin liquid phase. Magnetic susceptibility measurements suggest that this is related to distinct types of charge order induced by changes in lattice symmetry, in line with the theory of Chen et al. [Phys. Rev. B 93, 245134 (2016)PRBMDO2469-995010.1103/PhysRevB.93.245134]. The specific heat for samples at intermediate Sc concentration, which have the minimum breathing parameter, show consistency with the predicted U(1) quantum spin liquid.

Abstract
Objective: To evaluate the association between single nucleotide polymorphisms (SNPs) of RS1826690 located in UGT2B4 gene and pathological complete response (pCR) to neoadjuvant chemotherapy in breast cancer patients. Methods: A total of 146 breast cancer patients were enrolled to detect the SNPs of RS1826690 by sequenom. The relationship between SNPs of RS1826690 and pCR, predictors of pCR were analyzed by univariate or multivariate analysis. Results: The frequency of CC, CT and TT genetype of RS1826690 was 20.6%, 39.7% and 39.7%, respectively. Of the 171 patients, pCR was achieved in 39 cases (26.7%), with CC allele in 14 cases, CT allele in 7 cases and TT allele in 18 cases, and statistically significant difference was observed (χ(2)=16.684, P=0.003). Multivariate logistic regression analysis showed that SNPs of RS1826690 was an independent predictor of pCR (95% CI: 2.311-28.810, P=0.001) . SNPs of RS1826690 was statistically associated with estrogen receptor (ER) status (χ(2)=7.872, P=0.020). Conclusion: SNPs of RS1826690 was associated with pCR, and breast cancer patients with CC allele were more likely to achieve pCR.

Abstract
We report detailed dc and ac magnetic susceptibilities, specific heat, and thermal conductivity measurements on the frustrated magnet ZnCr_{2}Se_{4}. At low temperatures, with an increasing magnetic field, this spinel material goes through a series of spin state transitions from the helix spin state to the spiral spin state and then to the fully polarized state. Our results indicate a direct quantum phase transition from the spiral spin state to the fully polarized state. As the system approaches the quantum criticality, we find strong quantum fluctuations of the spins with behaviors such as an unconventional T^{2}-dependent specific heat and temperature-independent mean free path for the thermal transport. We complete the full phase diagram of ZnCr_{2}Se_{4} under the external magnetic field and propose the possibility of frustrated quantum criticality with extended densities of critical modes to account for the unusual low-energy excitations in the vicinity of the criticality. Our results reveal that ZnCr_{2}Se_{4} is a rare example of a 3D magnet exhibiting a field-driven quantum criticality with unconventional properties.

Abstract
Anaplasma are tick-borne obligatory intracellular bacteria, which infect humans and other animals. The Anaplasma species carried by ticks in China are not well studied. We collected 3145 questing Haemaphysalis longicornis ticks including 120 larvae, 2460 nymphs and 565 adults from vegetation in Jiaonan County, Shandong Province, China from 2013 to 2015. All ticks were examined for the presence of Anaplasma species by nested PCR amplification of the 16S rRNA gene. For further differentiation of A. capra from A. centrale, gltA and msp2 genes were sequenced for A. capra. Three Anaplasma species were detected in the nymph and/or adult ticks with the minimum infection rate of ticks as follows: 1.55% for A. bovis, 0.10% for A. phagocytophilum, and 0.03% for A. capra. These results indicated that the H. longicornis tick in Jiaonan County carried multiple Anaplasma species, which may be a challenge for public health in the studying area.

Abstract
Objective:To improve recognization of clinical, imaging and pathological characteristics of lymphoepithelial carcinoma (LEC) of the salivary glands.Method:The clinical manifestations, imaging features, histological and immunohistochemical characteristics of LEC of the salivary glands (n = 12) between 2003 and 2013 were retrospectively reviewed.Result: Four cases of male and 8 cases of female were enrolled, and the average age of 53.25 years. Ten lesions were located in the parotid gland, and 2 cases were in the submandibular gland. Two cases were unilateral multiple tumors, 10 cases were unilateral solitary tumor, 4 cases were with cervical lymph node metastasis and 1 case was with peripheral facial paralysis. Ten patients had positive EB VCA IgA test. Homogeneous density and obvious enhancement were achieved in all lesions on CT scan. 8 cases were with irregular shapes, partially or ill-defined margin, and heterogeneous enhancement. Incomplete capsule was found in 4 cases, while no obvious capsule was found in 6 cases. HE staining showed that the infiltrative tumors were formed by the presence of sheets or nests of epithelial cells and interstitial lymphoid tissue. Immunohistochemistry staining revealed that the epithelial cells were reactive for pan CK, the lymphoid cells showed reactivity for both CD20 and CD3 markers. All cases underwent primary tumor and involved gland resection with ipsilateral neck dissection, and postoperative radiotherapy, and 2 cases combined with postoperative chemotherapy. The 3 year survival rate of patients was 75.0%(9/12), and 3 cases died of local recurrence or (and) distant metastasis within 1-2 years of definite diagnosis.Conclusion: LEC of salivary gland is associated with EB virus infection. Most cases present with unilateral solitary mass, and incidence of regional lymph node involvement is high. The imaging characteristics of tumor seem to be malignant on CT scan in most cases. Treatment includes multimodality therapy including surgical resection, neck dissection, and radiotherapy. Local recurrence and distant metastasis are the main causes of death.

Abstract
INTRODUCTION Recently, hantaviruses have been discovered in insectivores in Europe, Asia, Africa, and North America. Imjin virus (MJNV) was first isolated from the lung tissues of Ussuri white-toothed shrew (Crocidura lasiura) from South Korea in 2009. We aim to detect the species and prevalence of insectivore- and rodent-borne hantaviruses in shrews and rodents. MATERIALS AND METHODS Shrews and rodents were captured in Jiaonan County of Shandong Province, China, in 2014. RT-PCR was used to amplify viral RNA of Hantavirus species, including insectivore-borne Imjin virus (MJNV), rodent-borne Hantaan virus (HTNV), and Seoul virus (SEOV) from shrews and rodents. RESULTS AND DISCUSSION We found that MJNV infected 10.7% (19/178) of Crocidura shrews, but it infected none of rodents (0/475); we also found that 2 of 178 (1.1%) Crocidura shrews were PCR positive to SEOV. This study indicated that the major animal hosts of Imjin virus are shrews, and rodent-borne SEOV can infect shrews.

Abstract
OBJECTIVE Community acquired pneumonia (CAP) is a common pulmonary infectious disease. Glucocorticoids (GCS) as one of the most powerful anti-inflammation drugs, are still the most controversial adjuvant therapy in treating CAP. Which sub-groups of CAP patients would benefit from GCS is a debating topic. Our aim of this study is to find the indications for GCS in treating adult CAP patients by using meta-analysis. METHOD "Steroids, glucocorticoids, corticosteroids, hydrocortisone, prednisone, cortisol, methylprednisolone, dexamethasone"and"community-acquired pneumonia"were used as key words both in Chinese and English to search all published literature in Pubmed, EMBASE MEDLINE, Cochrane, CNKI and Wanfang Database until March 2015. RESULTS All 840 articles were reviewed, and 11 high quality randomized clinical trials involving 1942 adult CAP patients were included in this meta-analysis. Using GCS did not significantly reduce mortality in all CAP patients (OR=0.68, 95%CI 0.46-0.99, P=0.04). But in the subgroup analysis, patients with severe CAP benefited from GCS treatment (OR=0.35, 95%CI 0.17-0.75, P=0.007). GCS also increased the risk of hyperglycemia (OR=1.99, 95%CI 1.50-2.65, P<0.000 01). CONCLUSION RESULTS from this meta-analysis suggested that GCS should only be rigorously used in severe CAP patients.

Abstract
OBJECTIVE To evaluate the role of glutamine-supplemented total parenteral nutrition (TPN) in severe acute pancreatitis. PATIENTS AND METHODS Forty-seven patients with severe acute pancreatitis were admitted to Huaihe Hospital, China, over a period of one year (July 2013 to June 2014) were randomly divided into two therapeutic groups. Patients in group 1 (24 patients in total) and group 2 (23 patient in total) were treated with glutamine-supplemented TPN and standard TPN respectively. Patients were assessed for nutritional parameters, the prevalence of complications, mortality, length of hospital stay (LOS) and length of TPN. RESULTS The majority of patients were male in both groups (62.5% in group 1 and 60.9% in group 2) and the average age was similar (39.13±4.46 years in group 1 and 40±3.96 years in group 2). The major causative factor was also similar in both groups, i.e. gall stones. The prevalence of complications in the group 2 was much higher (47.85%) than those in the group 1 (25%). The mortality rate for group 1 and 2 were 4.2% (1/24) and 17.4% (4/23), respectively. The length of hospital stay in the group 2 (23.08 ± 2.02 days) was longer than those of the group 1 (20.33 ± 2.40 days). The length of TPN was also longer in the group 2 (16.47 ± 2.72 days) than those of the group 1 (10.56 ± 2.21 days). Glutamine was also associated with significant increase in serum albumin level. CONCLUSIONS Glutamine-supplemented TPN can reduce the mortality and the occurrence of complications, shorten the length of stay and improve the nutritional status of the patients with severe acute pancreatitis.

Abstract
OBJECTIVE To compare the characteristics of naming impairment in Parkinson's disease (PD) without dementia, Parkinson's disease dementia (PDD) and Alzheimer's disease (AD). METHODS All participants came from outpatient clinic or inpatients of our hospital during 2011-2013. Object and action naming tests were evaluated among patients with PD without dementia (n=60), PDD (n=60), AD (n=60) and healthy control group (n=60). RESULTS The object naming score of PD without dementia group was 40.2±2.8, PDD group was 36.0±3.1, AD group was 31.6±4.0 and healthy control group was 44.1±2.2, while the action naming score of PD without dementia group was 27.3±2.6, PDD group was 20.5±4.0, AD group was 22.5±2.7 and healthy control group was 31.6±1.4. The object and action naming were both impaired in PD without dementia, PDD and AD patients compared with healthy control group (P<0.01). CONCLUSIONS PD patients without dementia have slight object and action naming impairments with more impairments in action naming. Action naming is more impaired in PDD patients, while object naming is more impaired in AD patients.

Abstract
Thermal conductivity (κ) of a distorted spin diamond-chain system, Cu3(CO3)2(OH)2, is studied at low temperatures down to 0.3 K and in magnetic fields up to 14 T. In zero field, the κ(T) curve with heat current along the chain direction has very small magnitudes and shows a pronounced three-peak structure. The magnetic fields along and perpendicular to the chains change the κ strongly in a way having good correspondence to the changes of magnetic specific heat in fields. The data analysis based on the Debye model for phononic thermal conductivity indicates that the heat transport is due to phonons and the three-peak structure is caused by two resonant scattering processes by the magnetic excitations. In particular, the spin excitations of the chain subsystem are strongly scattering phonons rather than transporting heat.
