Abstract
1. The goals of this study were to analyse the changes in microbiota composition of chilled chicken during storage and identify microbial biomarkers related to meat freshness.2. The study used 16S rDNA sequencing to track the microbiota shift in chilled chicken during storage. Associations between microbiota composition and storage time were analysed and microbial biomarkers were identified.3. The results showed that microbial diversity of chilled chicken decreased with the storage time. A total of 27 and 24 microbial biomarkers were identified by using orthogonal partial least squares (OPLS) and the random forest regression approach, respectively. The receiver operating characteristic (ROC) curve analysis indicated that the OPLS regression approach had better performance in identifying freshness-related biomarkers. The multiple stepwise regression analysis identified four key microbial biomarkers, including Streptococcus, Carnobacterium, Serratia and Photobacterium genera and constructed a predictive model.4. The study provided microbial biomarkers and a model related to the freshness of chilled chicken. These findings provide a basis for developing detection methods of the freshness of chilled chicken.

Abstract
Objective: To investigate the clinicopathological characteristics, diagnosis, differential diagnosis and prognostic factors of SMARCB1 (INI1)-deficient sinonasal carcinoma (SDSC). Methods: Sixteen cases of SDSC diagnosed in the Department of Pathology, Beijing Tongren Hospital from January 2016 to September 2020 were enrolled. Ninety-nine cases of small round cell malignant tumors of the head and neck were selected as the control, including poorly-differentiated squamous cell carcinoma (n=10), poorly-differentiated adenocarcinoma (n=5), undifferentiated carcinoma (SNUC, n=4), NUT carcinoma (n=5), neuroendocrine carcinoma (n=10), and other non-epithelial tumors [olfactory neuroblastoma (n=10), rhabdomyosarcoma (n=10), NK/T-cell lymphoma (n=10), malignant melanoma (n=10), Ewing's sarcoma/primitive neuroectodermal tumor (EWS/PNET, n=5)] and non-keratinizing undifferentiated nasopharyngeal carcinoma (n=20). The clinical and pathologic characteristics of SDSC, and immunohistochemical (IHC) expression of broad-spectrum CKpan, CK7, CK8/18, CK5/6, p63, p40, p16, INI1, NUT and neuroendocrine markers (Syn, CgA, CD56) were evaluated. In situ hybridization (ISH) was used to detect EBER and fluorescence in situ hybridization (FISH) to detect INI1 gene deletion. Results: The 16 cases of SDSC accounted for 1.3% (16/1 218) of all malignant sinonasal tumors in the author's unit during this time period, and 2.4% (16/657) of all malignant epithelial tumors. Microscopically, there was no clear squamous and adenomatous differentiation, but "rhabdoid-like" cells, are often seen. All SDSC cases were positive for CKpan and CK8/18, negative for INI1; Epstein-Barr virus was not detected by ISH; and INI1 gene deletion was observed in all 11 SDSC patients with FISH. Twelve cases were followed up for 3-47 months. One died of tumor-related diseases half a year after diagnosis, and the remaining patients were alive with tumor, the longest survival time was 47 months. Conclusion: SDSC should be differentiated from a variety of poorly-differentiated tumors in the sinonasal area. Histologically, SDSC has no clear differentiation, but the tumor cells are characteristically basal-like or rhabdoid-like, with non-specific vacuoles, translucent or vacuolar nuclei, prominent nucleoli and necrotic foci. They are negative for INI1 IHC staining, and FISH demonstrates INI1 gene deletion. The clinical prognosis is still unclear, further studies on its biologic behavior and treatment methods are warranted.

Abstract
The necrotrophic pathogen Sclerotinia sclerotiorum is one of the most damaging and economically important plant pathogens. Pydiflumetofen, which was developed by Syngenta Crop Protection, has already been registered in China for the management of Sclerotinia stem rot, which was caused by S. sclerotiorum in oilseed rape. In an attempt to preempt and forestall the development of resistance to this useful fungicide, the current study was initiated to investigate the potential mechanism of resistance in laboratory mutants. Five pydiflumetofen-resistant S. sclerotiorum mutants were successfully generated by repeated exposure to the fungicide under laboratory conditions. Although the mutants had greatly reduced sensitivity to pydiflumetofen, they were also found to have significantly (P < 0.05) reduced fitness, exhibiting reduced mycelial growth and sclerotia formation on potato dextrose agar medium. However, three of the four mutants had significantly (P < 0.05) increased pathogenicity on detached soybean leaves compared with their respective parental isolates, indicating a moderate to high level of fungicide resistance risk according to the criteria of the Fungicide Resistance Action Committee. Sequence analysis of four succinate dehydrogenase (Sdh) target genes identified several nucleotide changes in the sequences of the pydiflumetofen-resistant mutants, most of which were synonymous and caused no changes to the predicted amino acid sequences. However, all of the pydiflumetofen-resistant mutants had two amino acid point mutations (A11V and V162A) in their predicted SsSdhB sequence. No similar changes were found in the SsSdhA, SsSdhC, and SsSdhD genes of any of the mutants tested. In addition, there was a positive cross-resistance between pydiflumetofen and boscalid, and no cross-resistance between pydiflumetofen and other commonly used fungicides, including tebuconazole, fludioxonil, cyprodinil, dimethachlone, prochloraz, pyraclostrobin, fluazinam, procymidone, and carbendazim. These results indicate that pydiflumetofen has great potential as an alternative fungicide for the control of S. sclerotiorum, especially where resistance to other fungicides has already emerged. Mixing or alternate application with fludioxonil, prochloraz, and fluazinam could be used to limit the risk of resistance to pydiflumetofen.

Abstract
Objective: The 6th edition American Joint Committee on Cancer (AJCC) staging system for breast cancer classifies ipsilateral supraclavicular lymph node metastasis (ISLM) downing stage from M1 to N3, suggesting more patients might receive radical treatment. The aim of this study was to analyze the effect of ISLM on the prognosis of N3 breast cancer and verify the rationality of modified staging. Methods: A total of 321 breast cancer patients with N3 according to the 6th edition AJCC staging system were retrospectively analyzed. Propensity Score Matching (PSM) was used to pair the different subgroups of N3. The primary end point was disease-free survival (DFS), the secondary end point was overall survival (OS). Kaplan-Meier method was used to calculate the DFS and OS. The differences between two groups were analyzed by the Log-rank test. Results: After PSM pairing twice, 78 patients with none-ISLM and 78 patients with ISLM were enrolled in the first group; 51 patients with none-ISLM was compared patients with isolated ISLM in the second group. The results of the two groups showed that patients with none-ISLM have a prolonged DFS (the first group: 58.9 months vs 32.1 months, P=0.101; the second group: 59.0 months vs 44.0 months, P=0.533), while the OS was opposite (the first group: 87.4 months vs 140.4 months, P=0.289; the second group: 87.4 months vs 137.1 months, P=0.289). Conclusions: The prognosis of breast cancer patients with ISLM is similar to that of patients with none-ISLM in stage N3. It is reasonable to include ISLM in N3 in the 6th edition AJCC staging system. Yet, prospective studies with larger sample size are needed to further confirmation.

Abstract
Objective: To study the relationship between emotional apathy and motor symptoms, sleep, and cognitive function in patients with early Parkinson's disease (PD). Methods: One hundred and twenty-nine early PD patients who were treated in the Second Affiliated Hospital of Soochow University from June to October 2020 were included, including 82 male and 47 female patients. The emotional apathy was assessed by modified apathy rating scale (MAES). The above 129 patients were divided into 67 patients in the PD with emotional apathy group (MAES>14 points) and 62 patients in the PD without emotional apathy group (MAES≤ 14 points). Age, gender, course of disease and levodopa equivalent dose were also collected. Hoehn-Yahr stage and unified Parkinson's disease rating scale PartⅢ(UPDRS-Ⅲ), Pittsburgh Sleep Quality Index (PSQI), polysomnography, and Montreal Cognitive Assessment Scale (MoCA) were used to evaluate the motor symptoms, sleep and cognitive functions of patients with early PD, and the clinical characteristics of patients with early PD with apathywere determined. Results: Compared with PD patients without apathy, those with apathy had longer disease duration [M(Q1,Q3)][5.0 (3.0, 7.0) years vs 3.0 (2.0, 5.0) years, P=0.006] and severer motor symptoms [20.0 (10.0, 28.0) vs 14.0 (8.5, 23.0), P=0.047]. There was no significant difference in PSQI score between the two groups. Among the 33 patients who completed polysomnography, compared with PD patients without apathy (n=16), those with apathy (n=17) had a longer rapid eye movement (REM) sleep latency [150 (124, 184) min vs 87 (57, 133) min, P=0.035)] and more frequent periodic limb movements in the REM phase(P=0.042).The REM sleep ratio (r=0.373, P=0.042), apnea-hypopena index (AHI)(r=0.374, P=0.046) and oxygen deficit index (r=0.409, P=0.025) were positively correlated with the degree of apathy in PD patients. PD patients with apathy had relatively poorer performance in cognition assessment than those without apathy and total MoCA score was inversely correlated with the degree of apathy (r=-0.231, P=0.017). Conclusion: Early PD patients with apathy have objective sleep disorders dominated by REM sleep disorders, which can have a negative impact on cognitive function.

Abstract
Regression discontinuity design (RDD) is a rigorous quasi-experimental method. Based on the randomness of the distribution of samples around the critical value, the data on both sides are used for regression respectively, so as to avoid the interference of potential confounding factors and provide strong evidence for the inference of causal correlation. This study introduces the RDD and its research progress, and expounds its application in detail combined with cases, in order to provide reference for the application of RDD in epidemiological research.

Abstract
Objective: To explore the effects of scenario simulation teaching of junior nurses in a burns department on the fluid resuscitation care of massive burn patients during shock stage. Methods: From March 2018 to July 2019, 25 junior nurses fixed in the Department of Burn of Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine met the inclusion criteria and were recruited in this prospective before-after self-control study, including 21 females and 4 males, aged 23 to 26 years. They had a work experience of 1.0 (1.0, 2.0) years in the Department of Burn. Three teaching scenarios were made according to the three major problems in the fluid resuscitation nursing of extensive burn patients during shock stage. The teaching plans were written based on the theoretical framework of Jeffrie's nursing simulation teaching. The high feasibility and practicability of the teaching plans was verified through expert consultation and evaluation by junior nurses. According to the three scenarios in the teaching plan, the junior nurses were performed with scenario simulation teaching, with 2 hours for each scenario, 6 hours in total. In one month before and after the teaching (hereinafter referred to as before and after teaching), the comprehensive ability of junior nurses was evaluated by the teachers using the self-designed junior nurse comprehensive ability evaluation scale, and their behaviors were evaluated by themselves with Performance Self-rating Scale for Nursing Students on High Simulation Training. Data were statistically analyzed with paired sample t test. Results: After teaching, the scores on communication skills, patient admissions, condition assessments, fluid resuscitation, emergency treatment, drug management, nursing skills, instrument use, teamwork, and humanitarian care and total score in the comprehensive ability evaluation of junior nurses as evaluated by teachers were significantly higher than those before teaching (t=-8.060, -11.421, -17.232, -24.800, -4.670, -11.916, -12.131, -11.606, -14.632, -13.325, -25.068, P<0.01), with 4 items including fluid resuscitation, condition assessment, nursing skills, and equipment operation having higher scores. After teaching, the nurses' self-rating scores on communication, division of labor and cooperation, clinical decision-making, professional knowledge and skills, and professional development and critical thinking and total score were (4.6±0.4), (4.8±0.3), (4.6±0.3), (4.6±0.4), (4.6±0.4), and (23.2±1.5) points respectively, which were significantly higher than the corresponding scores of (4.1±0.7), (4.2±0.7), (3.9±0.5), (3.7±0.6), (3.9±0.5), and (18.8±2.6) points before teaching (t=-3.361, -5.721, -6.987, -7.923, -7.922, -7.367, P<0.01). Conclusions: With solving the practical problems in nursing works of fluid resuscitation care of massive burn patients during shock stage as entry point, scenario simulation teaching aims to train the clinical practice ability and adaptability of junior nurses, thereby improving junior nurses' comprehensive ability of clinical practice in the fluid resuscitation care of massive burn patients during shock stage, enhancing their self-confidence and critical thinking ability.

Abstract
Nonfullerene acceptors (MQ3, MQ5, MQ6) are synthesized using asymmetric and symmetric ladder-type heteroheptacene cores with selenophene heterocycles. Although MQ3 and MQ5 are constructed with the same number of selenophene heterocycles, the heteroheptacene core of MQ5 is end-capped with selenophene rings while that of MQ3 is flanked with thiophene rings. With the enhanced noncovalent interaction of O⋅⋅⋅Se compared to that of O⋅⋅⋅S, MQ5 shows a bathochromically shifted absorption band and greatly improved carrier transport, leading to a higher power conversion efficiency (PCE) of 15.64 % compared to MQ3, which shows a PCE of 13.51 %. Based on the asymmetric heteroheptacene core, MQ6 shows an improved carrier transport induced by the reduced π-π stacking distance, related with the increased dipole moment in comparison with the nonfullerene acceptors based on symmetric cores. MQ6 exhibits a PCE of 16.39 % with a VOC of 0.88 V, a FF of 75.66 %, and a JSC of 24.62 mA cm-2 .

Abstract
Objective: To preliminary explore the changes in blood system in pyrrolizidine alkaloids (PAs)-related liver damage. Methods: General situation, liver function, biochemical blood test, routine blood test, coagulation function markers, etc., of 77 cases with drug-induced liver damage admitted to the Zhongshan Hospital Affiliated to Fudan University from 2012 to 2019 were retrospectively analyzed. Patients' were divided into PA group, other traditional Chinese medicine group and Western medicine group according to their medication history. Simultaneously, the changes in liver function were observed in the established mice model of monocrotaline-induced liver damage. Liver tissues HE staining and blood routine indexes were observed. Results: 24 cases received PA, 24 cases received other traditional Chinese medicine, and 29 cases received western medicine. Alanine aminotransferase was lower in PA group than the other two groups (P < 0.05), and the total bilirubin and direct bilirubin were significantly lower than the other traditional Chinese medicine group (P < 0.05). The peripheral platelet count of the PA group was (84.11 ± 26.91) ×10(9)/L, which was significantly lower than the lower limit of normal, and had statistically significant difference with other traditional Chinese medicine and western medicine group (P < 0.01). Thrombocytocrit, mean platelet volume and platelet indices of PA group were statistically different from the other two groups (P < 0.05). The D-dimer level in patients with PA group was (2.62 ± 1.93) mg/L, which was higher than the upper limit of normal, and significantly higher than the D-dimer level of the other two groups of patients (P < 0.01). Meanwhile, prothrombin time was longer in PA group than that of the other two groups (P < 0.01), and platelets count were decreased significantly in the mouse model of monocrotaline-induced liver damage after alanine aminotransferase and aspartate aminotransferase elevation (P < 0.01). Conclusion: PA-related liver damage has lower peripheral platelet counts, and the peripheral platelet counts of these patients are lower than other types of drug-induced liver damage. In addition, increased D-dimer in patients with PA-related liver damage indicate a potential risk of thrombosis.

Abstract
Objective: To explore the prevalence and influencing factors of allergic conjunctivitis in Baotou area at different times. Methods: A cross-sectional study was conducted in January 2021, 111 patients with allergic conjunctivitis who were admitted to the Department of Ophthalmology, the Second Affiliated Hospital of Baotou Medical College, Inner Mongolia University of Science and Technology in 2020 were selected as the research subjects. The basic information, allergic conditions, living habits and other information of the patients were obtained by self-made questionnaire. The pollen concentration and allergy related indicators(allergic duration and frequency, eye itching score, eye burn score, eye foreign body sensation score, tears score and the total scores) of 2019 and 2020 were analyzed by paired sample t-test. The pollen concentration of 2019 and 2020 were analyzed by Wilcoxon signed rank test. The allergy related indicators of different genders were analyzed by independent sample t-test. The allergy related indicators of different ages were analyzed by one-way analysis of variance. The relationship between the length of wearing masks and the allergy related indicators were analyzed by Spearman correlation analysis. Results: Among the 111 patients with allergic conjunctivitis, 54 were males and 57 were females, ranging in age from 8 to 69 years old, with a median age of 35 years old and an average age of (36.77±13.18) years old. The average pollen concentration in Baotou in 2019 was (125.35±222.64) grains/1 000 square millimeter, and the average pollen concentration in Baotou in 2020 was (107.38±137.29) grains/1 000 square millimeter. There was no significant difference in pollen concentration between the two years(Z=-0.178, P=0.859). The severity of allergic indicators in all patients in 2020 is significantly lower than in 2019(t values were 4.701,3.587,2.582,3.661,4.444,2.784,2.555,3.886,respectively, with P<0.05). The severity of allergic indicators in male patients is lower than that of female patients (t values were -1.558, -1.257, -3.41, -3.085, -2.335, -2.897, -2.652, -4.124, respectively). The prevalence of allergic conjunctivitis dose not vary significant with age (P values were 0.504, 0.095, 0.499, 0.265, 0.284, 0.655, 0.421, 0.976, respectively). In 2020, the average time that patients wear masks is (6.55±3.28) h/d, and there is a correlation with the difference in allergy duration (r=0.191, P=0.045). Conclusion: The severity of allergic conjunctivitis in Baotou in 2020 was significantly improved compared with that in 2019, which may be related to masks wearing.

Abstract
Objective: To discuss the effect of low-dose ionizing radiation on the health of radiation workers, and provide a basis for occupational health risk assessment of radiation workers. Methods: In January 2020, 3165 radiation workers who performed radiation occupational health examinations in Guangzhou Prevention and Treatment Hospital for Occupational Disease from January 2017 to December 2019 were selected as the research objects, and compared and analyzed the health status of radiation workers with different examination types (pre-job, in-job and off-job) , types of work, gender, and length of service. Results: The off-job occupational radiological health examination was rare at 2.3% (74/3165) . The abnormal detection rate of chest radiographs, renal function, thyroid function, and blood routine of the radiation workers in-job group was higher than that of the pre-job group (P<0.05) . No statistical difference was found in the abnormal detection rate of the examination items during the in-job group and the off-job group (P>0.05) . The blood routine abnormality detection rate of medical application group and industrial application group were higher than those of nuclear fuel group (P<0.05) . The abnormal detection rate of blood pressure and renal function of male radiation workers was higher than that of females, while the abnormal detection rate of blood routine of females was higher than that of males (P<0.05) . The abnormal detection rate of electrocardiogram, chest radiograph, blood pressure, renal function, thyroid function, and blood routine of radiation workers increased with increasing working age (P<0.05) . Conclusion: Occupational health status of radiation workers is not optimistic. Radiation occupational health monitoring should be strengthened, special attention should be paid to off-job radiation occupational health examination, focusing on the sensitive indicators of sensitive personnel, improving radiation protection conditions, and effectively protecting the occupational health of radiation workers.

Abstract
BACKGROUND The impact of molecular alterations on programmed death-ligand 1 (PD-L1) combined positive score (CPS) is not well studied in gastroesophageal adenocarcinomas (GEAs). We aimed to characterize genomic features of tumors with different CPSs in GEAs. PATIENTS AND METHODS Genomic alterations of 2518 GEAs were compared in three groups (PD-L1 CPS ≥ 10, high; CPS = 1-9, intermediate; CPS < 1, low) using next-generation sequencing. We assessed the impact of gene mutations on the efficacy of immune checkpoint inhibitors (ICIs) and tumor immune environment based on the Memorial Sloan Kettering Cancer Center and The Cancer Genome Atlas databases. RESULTS High, intermediate, and low CPSs were seen in 18%, 54% and 28% of GEAs, respectively. PD-L1 positivity was less prevalent in women and in tissues derived from metastatic sites. PD-L1 CPS was positively associated with mismatch repair deficiency/microsatellite instability-high, but independent of tumor mutation burden distribution. Tumors with mutations in KRAS, TP53, and RAS-mitogen-activated protein kinase (MAPK) pathway were associated with higher PD-L1 CPSs in the mismatch repair proficiency and microsatellite stability (pMMR&MSS) subgroup. Patients with RAS-MAPK pathway alterations had longer overall survival (OS) from ICIs compared to wildtype (WT) patients [27 versus 13 months, hazard ratio (HR) = 0.36, 95% confidence interval (CI): 0.19-0.7, P = 0.016] and a similar trend was observed in the MSS subgroup (P = 0.11). In contrast, patients with TP53 mutations had worse OS from ICIs compared to TP53-WT patients in the MSS subgroup (5 versus 21 months, HR = 2.39, 95% CI: 1.24-4.61, P = 0.016). CONCLUSIONS This is the largest study to investigate the distinct genomic landscapes of GEAs with different PD-L1 CPSs. Our data may provide novel insights for patient selection using mutations in TP53 and RAS-MAPK pathway and for the development of rational combination immunotherapies in GEAs.

Abstract
Highly soluble d8-d10 heteronuclear phosphors afford an alternative approach to achieve high-efficiency organic light-emitting diodes (OLEDs) through a solution process. In this work, four highly phosphorescent d8-d10 heteronuclear complexes with significant Pt-Au interactions were prepared. By judicious selection of sterically hindered and π-conjugated substituents in triphosphine ligands, the phosphorescence is dramatically promoted through effectively prohibiting nonradiative thermal relaxation with an efficiency of 0.94-0.99 in doping films. Exploiting highly emissive Pt-Au complexes as phosphorescent dopants, ultrahigh-efficiency solution-processed OLEDs were attained. The peak current efficiency, power efficiency, and external quantum efficiency are 96.2 cd A-1, 65.0 lm W-1, and 26.4% for the green-emitting PtAu2 phosphor and 68.6 cd A-1, 42.5 lm W-1, and 25.1% for the orange-emitting Pt2Au phosphor, which represent the state-of-art for solution-processed OLEDs based on non-iridium phosphors.

Abstract
Objective: To evaluate the current status of the registered pediatric drug or vaccine clinical trials in China for the purpose of providing a reference for the development of pediatric clinical trials in China. Methods: We collected the data about registered pediatric clinical trials that were conducted from September 6, 2013(Mandatory registration start date) to September 6, 2019 (Cut-off date) at Chinadrugtrials.org.cn platform. The survey items included trial name and number, drug classification, sponsor's information, current trial status, completion status, etc. The clinical trials were categorized by drug group (includes chemical medicine, traditional Chinese medicine and natural medicine, biological products) and by vaccine group. Results: During the six years 349 pediatric clinical trials were registered on the platform, including 162 pediatric drug trials and 187 vaccine trials. The numbers of chemical drugs and biological products registered in 2018 were 23 and 11, respectively, the highest in the history. The number of pediatric clinical trials of traditional Chinese medicine and natural medicine was 11 in 2014, but from 2015 to 2018 only 2 to 4 trials were registered each year. The overall completion rates of the registered drug and vaccine clinical trials were 22.8% (37/162) and 41.7%(78/187), respectively. Only 42 international multicenter pediatric clinical trial projects were registered on the platform. The numbers of drug and vaccine phase Ⅰ clinical trials were 4 and 46, respectively. Thirty-six pediatric endocrine system agent clinical trials were carried out, with the largest number of all the drug categories registered on the platform. Conclusions: In recent years the number of registered pediatric drug and vaccine clinical trials increased in China. However, the number is still very limited. It is urgent to further promote the development of pediatric clinical trials.

Abstract
In this work, rational design of highly soluble and phosphorescent Ag-Au cluster complexes with exceptional [2]catenane structures is conducted using 1,8-diethynyl-9H-carbazole (H3decz) as a rigid U-shaped ligand with a distinguished hole-transport character. The self-assembly reaction of H3decz, Au+, and Ag+ generated phosphorescent Ag4Au6 cluster 1 (Φem = 0.22 in CH2Cl2) with H2decz- having a free ethynyl (-C≡CH) group. When the four free C≡CH groups in the Ag4Au6 complex 1 are further bound to four (PPh3)Au+ and four (PPh3)Ag+ moieties through M-acetylide linkages, the formation of Ag8Au10 cluster 2 not only eliminates nonradiative ethynyl C-H vibrational deactivation process but also improves dramatically the molecular rigidity so that the phosphorescent efficiency of the Ag8Au10 cluster 2 (Φem = 0.63) is nearly 3 times that of the Ag4Au6 cluster 1. The Ag8Au10 cluster structure is further rigidified using diphsophine Ph2P(CH2)4PPh2 (dppb) in place of PPh3 so that the phosphorescence of the Ag8Au10 cluster 3 (Φem = 0.77) is more efficient than that of 2. Making use of the Ag8Au10 clusters as phosphorescent dopants, high-efficiency solution-processed organic light-emitting diodes (OLEDs) were achieved with current efficiency (CE) and external quantum efficiency (EQE) of 47.2 cd A-1 and 15.7% for complex 2 and 50.5 cd A-1 and 14.9% for complex 3.

Abstract
Objective: To explore the relationship between occupational stress and metabolic syndrome (MS) in operating room nurses. Methods: In July 2019, 179 nurses in the operating room of a third-class A hospital in Shandong Province were selected as the research objects. The self-designed questionnaire was used to investigate the general situation, and "Nurse Job Stressor Scale" was used to investigate the occupational stress level of nursing staff. The height, weight, waist circumference, blood pressure, fasting blood glucose, total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, ischemia-modified albumin, lipoprotein associated phospholipase A2 were measured. The nursing staff were divided into MS group and non-MS group, and the occupational stress levels of the two groups were compared. Chi square test or Fisher test were used to compare the counting data between groups; the measurement data were expressed by Mean±SD, and the comparison between groups was performed with t test. Multiple logistic regression analysis was used to analyze the influencing factors of MS. Results: The overall occupational stress level of nurses in operating room was (450.58±141.77) points, which was significantly lower than the norm score (P<0.05) ; Compared with non-MS group, the overall occupational stress level, work nature, workload and patient related factors in MS group were significantly higher, and the differences were statistically significant (P<0.05) ; The prevalence of abdominal obesity, hypertriglyceridemia, hyperglycemia and hypertension were significantly different among the groups with different occupational stress levels (P<0.05) . After adjusting waist circumference, triglyceride, systolic blood pressure, high density lipoprotein, ischemia modified albumin and lipoprotein associated phospholipase A2, the total score of occupational stress was the risk factor of MS in operating room nurses (P<0.05) . Conclusion: The occupational stress level of nurses in operating room is related to the prevalence of MS.

Abstract
The reaction of 3,6-ditert-butyl-1,8-bis(diphenylphosphino)-9-methyl-9H-carbazole (L) with CuBr resulted in the isolation of tetranuclear copper(I) complex Cu4Br4L2 as two colorless crystal morphs, i.e., green-emitting 1G and yellow-emitting 1Y. As demonstrated by X-ray crystallography, the Cu4Br4 moiety in both 1G and 1Y adopts the same chair conformations. When L is bonded perpendicularly to the Cu4 plane, 1G with green emission is obtained, while it gives a yellow emission of 1Y once the L is parallelly bonded to Cu4 plane. Theoretical computational studies suggest that the variation in ligand orientation results in a different degree of structural distortion in triplet state and thus different luminescent energy. Particularly, 1Y undergoes dramatic structural distortion from the ground (S0) to triplet excied state (T1). Interestingly, 1G can be converted into 1Y upon exposed to saturated hexane vapor, which would return to 1G upon exposure to acetonitrile vapor. As demonstrated experimentally and theoretically, the reversible luminescence transformation between 1G and 1Y is ascribed to the variation of ligand L orientations.

Abstract
Mechanochromic luminescence materials have attracted rapidly growing interest. Nevertheless, the designed synthesis of such materials remains a challenge, and there have been few examples based on weak intramolecular interactions. Herein, we report a new approach for preparing mechanochromic luminescence materials of Cu(I) complexes, i.e., constructing a photoluminescence system that bears a large coplanar multinuclear Cu(I) unit showing weak intramolecular π···π interactions with the planar rings of the coordinated ligands in the molecule. Using it, a series of novel mechanochromic luminescent tetranuclear Cu(I) complexes have been successfully designed and synthesized. As revealed by single-crystal X-ray crystallography, these Cu(I) complexes share an identical {Cu4[μ3-η2(N,N),η1(N),η1(N)-pyridyltetrazole]2}2+ planar fragment whose coplanar pyridyl rings exhibit weak intramolecular π···π interactions with the phenyl rings of the coordinated phosphine ligands in the molecule. All of these Cu(I) complexes exhibit reversible mechanochromic luminescence, which can be attributed to the change in the rigidity of the molecular structure resulting from the disruption and restoration of intramolecular π···π interactions between the pyridyl and phenyl rings triggered by grinding and CH2Cl2 vapor, as supported by powder X-ray diffraction and Fourier transform infrared spectrometry. In addition, the results might provide a new route for developing mechanochromic luminescence materials of Cu(I) complexes for intelligent responsive luminescent devices.

Abstract
Recipients who detect hepatitis C virus (HCV) ribonucleic acid during the liver transplantation will promptly infect the transplanted liver, so it is called recurrent HCV after liver transplantation. HCV recurrence can lead to the progression of fibrosis and cirrhosis to the transplanted liver, and thereby significantly reduce the transplanted liver survival rate. Therefore, the effective elimination of HCV is the key to improve the patients' prognosis. Patients should receive antiviral therapy as long as HCV RNA can be detected after liver transplantation, and treatment should be stopped as soon as the disease condition stabilizes. Currently, highly safe pan-genotypic direct-acting antiviral drugs (DAA) have been recommended to patients after liver transplantation, as their interaction with immunosuppressive drugs (DDI) is minimal. Clinically, different treatment scheme should be selected according to the hepatorenal function, and DDIs of the patient. This article reviews the current situation and progress of antiviral treatment for HCV infection after liver transplantation.

Abstract
Objective: To investigate the effects of long-term ionizing radiation on peripheral blood cells of nuclear power workers. Methods: In March 2019, a total of 530 radiation exposed workers in the nuclear power industry who underwent in-service radiation occupational health examination in Guangzhou occupational disease prevention and control hospital in 2018 and with service age ≥1 year were selected as the radiation group. At the same time, 545 workers in nuclear power industry were selected as control group. According to the methods and requirements of GBZ 235-2011 "technical specification for occupational health monitoring of radiation workers" and GBZ 98-2017 "health requirements for radiation workers", the occupational health monitoring data were collected, and the change rules of peripheral blood cells in the two groups were analyzed. Results: Compared with the control group, the total number of WBC, NEUT, LYMP, Hb, MCV and MCHC in radiation group were lower than those in control group (P<0.05) , and the difference was statistically significant (P<0.05) . The MPV increased significantly (P<0.05) . Compared with the control group, the abnormal rate of WBC and Hb in the radiation group was higher than that in the control group (P<0.01) , but there was no significant difference in the abnormal rate of RBC and PLT (P>0.05) . Conclusion: Low dose ionizing radiation has a certain cumulative damage effect on peripheral blood cells of radiation workers in nuclear power industry. The change rules of different cell subtypes are different, and the changes of WBC and PLT appear earlier.

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: To compare the clinical efficacy of transjugular intrahepatic portosystemic shunt (TIPS) with expanded polytetrafluoroethylene (ePTFE)-covered stent and drug combined with gastroscopy as the secondary prevention of esophageal-gastric variceal bleeding in portal hypertension. Methods: Patients with esophageal-gastric variceal bleeding who received TIPS treatment (ePTFE covered stent) or gastroscopy for the first time as the secondary prevention for portal hypertension at Nanfang Hospital of Southern Medical University through March to July 2017 were selected. One year after the operation, liver function changes, ascites remission rates, incidence of hepatic encephalopathy, re-bleeding rate, average hospitalization frequency and expenses, survival time, as well as the TIPS patency conditions were analyzed in the two groups of patients. 2 test, Kaplan-Meier method and Mann-Whitney U test were used to analyze the data. Results: There were 74 and 66 cases in the TIPS and the drug combined gastroscopy group and the follow-up duration (14.57 ± 0.79) was 12-16 months. One year after surgery, the remission rate of ascites in the TIPS group was higher 57.1% (32/56) than that of the drug combined gastroscopy group (0), and the difference was statistically significant (χ(2) = 2 = 36.73, P < 0.01). The cumulative incidence of hepatic encephalopathy at 1, 3, 6, and 12 months after surgery in the TIPS group was 32.4% (24/74), 37.8% (28/74), 40.5% (30/74), and 40.5% (30/74), respectively. The cumulative incidence of hepatic encephalopathy in the drug combined gastroscopy group was 3.0% (2/66), 3.0% (2/66), 3.0% (2/66), and 6.1% (4/66), respectively. Kaplan-Meier analysis showed that the cumulative incidence of hepatic encephalopathy in the TIPS group was higher than that of the drug combined gastroscopy group (χ(2) = 11.29, P < 0.01). The incidence of severe hepatic encephalopathy ( grade III to IV) at 1, 3, 6, and 12 months after surgery in the TIPS group was 2.7% (2/74), 0, 0, and 0, respectively. The incidence of severe hepatic encephalopathy in drug combined gastroscopy group was 0, and there was no statistically significant difference in development of hepatic encephalopathy between the two groups (P > 0.05). The re-bleeding rates of TIPS group and drug combined gastroscopy group were 0 and 27.3% (18/66), respectively, and the difference was statistically significant (χ(2) = 22.42, P < 0.01). There was no death reported during the follow-up period between both groups. The hospitalization frequency times (1.45 ± 0.80) in TIPS group was lower than that of the drug combined gastroscopy group times (3.24 ± 1.80), and the difference was statistically significant (U = -4.52, P < 0.01). Conclusion: In the prevention of esophageal-gastric variceal bleeding, TIPS (ePTFE-covered stent) treatment has the advantages of reducing re-bleeding rate, high ascites remission rate and hospitalizations frequency. In addition, patients treated with TIPS have a higher incidence of hepatic encephalopathy than that of drugs combined with gastroscopy. However, TIPS did not exacerbate the incidence of hepatic encephalopathy, and there was no significant difference in the 1-year survival rate after TIPS and drugs combined with gastroscopy treatment.

Abstract
Objective: To investigate the fertility needs and outcome of pregnancy in patients with young breast cancer in China. Methods: A retrospective cross-sectional investigation was conducted on 374 young breast cancer women from Cancer Hospital, Chinese Academy of Medical Sciences. Young patients with breast cancer were defined as patients who got initial diagnosis of breast cancer at age no more than 40 years old. We conducted a questionnaire survey and collected clinical data from medical chart. Logistic regression model was used to analyze the possible factors influencing patients' fertility intention. Results: 308 young women with breast cancer completed questionnaires, and the response rate was 82.4%. 81 patients (26.3%) had fertility needs after diagnosis. Of them, 6 cases took active measures to preserve fertility. 72 patients (23.4%) received fertility counseling during treatment. 7 patients were successfully pregnant, including four cases who delivered normally. Multivariate logistic regression analysis showed that patients under 35 years old (OR=4.81), bachelor degree or above (OR=3.26), receiving breast-conserving surgery (OR=2.15) and childless patients (OR=3.03) were more likely to have fertility needs after diagnosis of breast cancer (all P<0.05). Conclusions: The fertility needs of young breast cancer women in China are gradually increasing. Healthcare providers associated with tumor patients should actively offer corresponding fertility consultation and individualized diagnosis and therapy plans for patients with fertility needs.

Abstract
Objective: To explore the necessity, feasibility, technical points, operative complications and prognosis of mechanical thrombectomy for distal branch occlusion of middle cerebral artery. Methods: Mechanical thrombectomy was performed on 42patients (28 males,14 females; age ranged from 43 to 88 years, mean 65.48years)with distal branch occlusion of middle cerebral artery (M2, M3), between May 2017 to July 2019. Theclinical feature was retrospectively analyzed. The NIHSS score before operation, 24 hours after operation and 1 week after operation, the recanalization of occluded vessels during operation, the complications and the recovery after 3 months (3 months mRS score) were analyzed. Results: Of the 42 patients, 38 patients were successfully recanalized, and the recanalization rate was 90.48%. Postoperative hemorrhage in 6 cases and vasospasm in 17 cases. At 90 days after operation, the mRS score was 0 in 13 cases, 1 in 11 cases, 2 in 6 cases, and 0 cases died. Conclusions: Mechanical thrombotomy is safe and feasible for patients with distal branch occlusion of middle cerebral artery (M2, M3). However, the risks and benefits of patients should be fully considered.

Abstract
The epidemiological history and clinical characteristics of 7 cases of COVID-19 and 1 case of close contact in the first family aggregation epidemic of COVID-19 in Gansu Province were analyzed. The first patient A developed on January 22, 2020, with a history of residence in Wuhan, and confirmed severe cases of NCP on January 24, 2020; patient B, on January 23, 2020, diagnosed on January 31, severe cases; patient C, asymptomatic, diagnosed on January 27; patient D, asymptomatic, diagnosed on January 27; patient E, on January 24, diagnosed on January 28; patient F, asymptomatic, diagnosed on January 31; Patient G was asymptomatic and was diagnosed on January 31. In close contact, H was asymptomatic, PCR test was negative and asymptomatic, and he was discharged early. Among the 7 patients, 1 case died of (B) aggravation, and the other patients' condition was effectively controlled after active treatment. Except for the discharged cases, 5 cases were positive for COVID-19 specific IgM antibody and 1 case was negative. In this clustering outbreak, 4 patients remained asymptomatic, but PCR and IgM antibodies were positive, indicating that asymptomatic patients may be the key point to control the epidemic. Specific IgM antibody screening for patients whose pharyngeal swab nucleic acid test is negative but with ground glass-like lung lesions is very important for early detection and early isolation.

Abstract
BACKGROUND Gastrointestinal (GI) dysfunction is a common and important complication of acute pancreatitis (AP), especially in patients with severe AP. Despite this, there is no consensus means of obtaining a precise assessment of GI function.
AIM To determine the association between acute gastrointestinal injury (AGI) grade and clinical outcomes in critically ill patients with AP.
METHODS Patients with AP admitted to our pancreatic intensive care unit from May 2017 to May 2019 were enrolled. GI function was assessed according to the AGI grade proposed by the European Society of Intensive Care Medicine in 2012, which is mainly based on GI symptoms, intra-abdominal pressure, and feeding intolerance in the first week of admission to the intensive care unit. Multivariate logistic regression analysis was performed to assess the association between AGI grade and clinical outcomes in critically ill patients with AP.
RESULTS Among the 286 patients included, the distribution of patients with various AGI grades was 34.62% with grade I, 22.03% with grade II, 32.52% with grade III, and 10.84% with grade IV. The distribution of mortality was 0% among those with grade I, 6.35% among those with grade II, 30.11% among those with grade III, and 61.29% among those with grade IV, and AGI grade was positively correlated with mortality (χ2 = 31.511, P < 0.0001). Multivariate logistic regression analysis showed that age, serum calcium level, AGI grade, persistent renal failure, and persistent circulatory failure were independently associated with mortality. Compared with the Acute Physiology and Chronic Health Evaluation II score (area under the curve: 0.739 vs 0.854; P < 0.05) and Ranson score (area under the curve: 0.72 vs 0.854; P < 0.01), the AGI grade was more useful for predicting mortality.
CONCLUSION AGI grade is useful for identifying the severity of GI dysfunction and can be used as a predictor of mortality in critically ill patients with AP.

Abstract
Objective: Introduce the surgical techniques of bridge-shaped flap penetrating keratoplasty and whole lamellar keratoplasty with corneoscleral limbal and the comparison of therapeutic effects on keratoglobus. Methods: Five patients (eight eyes) with keratoglobus from January 2010 to December 2015 were included. Three eyes received bridge-shaped flap penetrating keratoplasty (two eyes with corneal penetrating injury due to trauma, one eye with descemet's membrane detachment) and five eyes received whole lamellar keratoplasty with corneoscleral limbal. Results: The patients (four male, one female) aged 3 to 67 years old. Three younger patients were complicated with blue sclera. The visual acuity of all the patients pre-operation were lower than 0.05. The average visual acuity after whole lamellar keratoplasty (LKP) surgery was 0.2, while the average visual acuity after bridge-shaped flap penetrating keratoplasty (PKP) was 0.5. The corneal epithelium of the three eyes received bridge-shaped flap PKP surgery was completely healed within a week with no recurrence of corneal epithelial defect. Whereas one eye after whole LKP surgery arised persistent corneal epithelial defect and healed after blepharorrhaphy. The corneal epithelial of another eye after whole LKP surgery healed slowly and was completely healed after wearing a bandage lens on corneal for 2 months. The corneal epithelial of the remaining three eyes after whole LKP surgery was completely healed within a week. Two eyes received bridge-shaped flap PKP surgery arised corneal graft rejection 2 months after operation and recovered after anti-rejection treatment. No corneal graft rejection arised in the patients receiving whole LKP surgery. Conclusions: The whole lamellar keratoplasty with corneoscleral limbal could effectively reinforce corneal, avoid corneal penetrating injury caused by minor trauma, and improve visual acuity in keratoglobus whose corneas were gradually thinning and corrected vision cannot be improved. The patients with corneal perforating injury or descemet's membrane detachment could obtain good visual prognosis receiving bridge-shaped flap penetrating keratoplasty.

Abstract
Bis(diphenylphosphinomethyl)phenylphosphine (dpmp)-supported Pt2Au heterotrinuclear complexes [Pt2Au(dpmp)2(C≡CPh)4](ClO4) (1), [Pt2Au(dpmp)2(DEBf)(C≡CPh)2](ClO4) (2), and [Pt2Au(dpmp)2(DECz)(C≡CPh)2](ClO4) (3) were prepared and used in organic light-emitting diodes (OLEDs) as a new class of light emitters, where DEBf = dibenzofuran-4,6-diacetylide and DECz = 3,6-di-tert-butylcarbazole-1,8-diacetylide. Although the flexible structure of Pt2Au complex 1 (λem = 503 nm, Φem < 0.1%) results in weak photoluminescence in fluid CH2Cl2, complexes 2 (λem = 585 nm, Φem = 4.9%) and 3 (λem = 589 nm, Φem = 3.2%) with a rigid conformation give a much stronger phosphorescence. The displacement of two σ-bonded phenylacetylide ligands with a diacetylide ligand such as DEBf and DECz to fasten Pt2Au structures facilitates greatly luminescent emission so that the emissive quantum yield in doping film is as high as 89% for 2 and 93% for 3. As revealed by a theoretical study, the severe structural distortion of diacetylide-linked Pt2Au complexes 2 (λem = 585 nm) and 3 (λem = 589 nm) in a triplet excited state gives rise to significant red shifts of phosphorescent emission spectra relative to that of complex 1 (λem = 503 nm). By means of Pt2Au complexes as phosphorescent emitters, solution-processed OLEDs achieved a relatively low external quantum efficiency (EQE < 9.5%) when commercial poly(ethylenedioxythiophene):poly(styrenesulfonic acid) (PEDOT:PSS) was used as the hole-injection layer (HIL). In contrast, the peak EQE was increased to 18.3% with a dramatic increase of efficiency by the use of modified HILs composed of PEDOT:PSS and PSS-Na, which provide a higher work function and a better film morphology.

Abstract
OBJECTIVE To explore the effects of Mg2+ on the expression of osteoarthritic markers in human cartilage and synovium tissue explants. To investigate the therapeutic effect of intra-articular injection of Mg2+ in an established rat OA (Osteoarthritis) model of anterior cruciate ligament transection with partial medial meniscectomy (ACLT + PMM). DESIGN Human cartilage and synovium explants were collected from total knee replacement surgeries and incubated with MgCl2 (20 mmol/L) in vitro. A rat OA model was established by ACLT + PMM surgery in 450-500 g male Sprague Dawley (SD) rats. To select the optimal dose, intra-articular injections of MgCl2 (0.05, 0.5, 5 mol/L) were performed at 4 weeks after the surgery every 3 days for 2 weeks. The effect of optimized MgCl2 was further determined by histology, immunohistochemistry, and quantitative real-time polymerase chain reaction. RESULTS The expressions of osteoarthritic markers in human cartilage and synovium explants were inhibited by Mg2+in vitro. Immunohistochemical analysis further suggested the inhibitory effects of Mg2+ on the expression of MMP-13 and IL-6 in the human tissue explants. Cartilage degeneration and synovitis in ACLT + PMM rats were significantly improved by intra-articular injections of Mg2+ (0.5 mol/L). Immunohistochemical analysis also showed the regulatory effects of Mg2+ on osteoarthritic markers in both cartilage and synovium in rats, consistent with in vitro results. CONCLUSION Intra-articular injections of Mg2+ at 0.5 mol/L attenuate the progression of OA in the ACLT + PMM rat model. Such effect was at least in part explained by the promotion of cartilage matrix synthesis and the suppression of synovial inflammation.

Abstract
Objective: To validate whether the prognostic stage groups by the 8th edition of the American Joint Committee on Cancer (AJCC) staging system provides improved prognostic accuracy in T1-2N1M0 postmastectomy breast cancer patients compared to 7th edition. Methods: a total of 1 823 female patients with T1-2N1M0 breast cancer who underwent mastectomy and axillary lymph node dissection without neoadjuvant chemotherapy were analyzed and restaged according to 8th edition. Univariate analysis of prognostic factors was evaluated by using log-rank test. Multivariate analysis was estimated by using the Cox proportional hazards model. The prognostic accuracy of the two staging systems was compared using receiver operating characteristic (ROC) analyses and the concordance index (C-index). Results: 5-year locoregional recurrence rate (LRR) for the whole group was 6.0%, 5-year distant metastasis (DM) rate was 11.5%, 5-year disease-free survival (DFS) was 85.0%, and 5-year overall survival (OS) was 93.1%. Cox analysis showed that 7th edition of the AJCC staging system and progesterone receptor status were independent risk factors for LRR, DM, DFS and OS (P<0.05). Compared with stage by 7th edition, 1 278(70.1%) were assigned to a different prognostic stage group: 1 088 (85.1%) to a lower stage and 190 (14.9%) to a higher stage. LRR, DM, DFS and OS were significantly different between prognostic stage ⅠA, ⅠB, ⅡA, ⅡB and ⅢA according to 8th edition of the AJCC staging system(P<0.001). Prognostic stage had significantly higher C-indexes and provided better estimation of prognosis compared to stage by 7th edition of the AJCC staging system (P<0.001). Conclusion: The prognostic stage groups of 8th edition AJCC staging system has superior prognostic accuracy compared to 7th edition in T1-2N1M0 breast cancer, and has better clinical therapeutic guidance value.

Abstract
Objective: To assess the effectiveness and safety of sacral neuromodulation (SNM) therapy for men with idiopathic dysuria. Methods: From January 2012 to December 2016, a total of 26 patients treated with SNM therapy from multi-center across the country were retrospectively studied. The age ranged from 19 to 86 years with an average age of 45.2 years. Patients suffered from one or multiple urinary symptoms such as frequency of urination, urgency, urinary retention, etc. All patients had received more than two types of conservative therapy including oral and behavioral therapy, but had poor or no improvement. The voiding diary, urgency score and the quality of life score before implantation, in stageⅠ after implantation and stage Ⅱ after permanent implantation were recorded and compared. Results: A total of 22 patients chose to receive IPG at the end of stageⅠ therapy while 4 patients refused further stage Ⅱ therapy because of dissatisfactory effect. The conversion rate of stage Ⅰ to stage Ⅱ was 84.6% (22/26). The average follow-up time was 19.2 months, ranging from 3 to 63 months. The baseline of residual urine, voiding frequency and average voiding amount and those after stage Ⅰ therapy were [5 (0, 137.5) ] ml vs [0 (0, 40) ] ml, 14.6±6.1 vs 9.1±2.8, [100 (80, 135) ] ml vs [190 (150, 210) ] ml, respectively. The differences were statistically significant(all P<0.05).However, no significant differences were found in urination volume and quality of life (QoL) before and after implantation(P>0.05). During an average follow-up time of 19.2 months after the permanent implantation, over 80% patients had an improvement of residual urine volume by more than 50% after permanent implantation while the improvement was 55.6% after stage Ⅰ therapy, suggesting that the improvement of residual urine volume might be positively correlated with the duration of regulation. No significant differences were found in other parameters between stage Ⅰ and Ⅱ therapy. No adverse events like wound infection and electrode dislocation happened during our study. Conclusions: SNM is an effective and safety procedure for male patients with idiopathic dysuria, with a relatively high transfer rate. The medium-term curative effect is stable. The duration of regulation may be positively correlated with the improvement of residual urine.

Abstract
Objective: To analyze clinical effects of modified Yokoyama's surgery combined with medial rectus muscle recession for treatment of high myopic strabismus fixus. Methods: Retrospective analysis of records of 9 patients (14 eyes) with high myopic strabismus fixus treated from February 2013 to December 2016 in the Department of Ophthalmology, Xiangya Hospital, Central South University. All patients underwent modified Yokoyama's surgery. The temporal 1/2 of the superior rectus (SR) and the superior 1/2 of the lateral rectus (LR) were united 12 to 14 mm, combined with medial rectus muscle recession. The angle of deviation of primary position, the mobility of the affected eye, and the change of CT imaging were observed and analyzed before and 6 months after surgery. Statistical analysis was performed by Mann-Whitney U test. Results: The patients were 5 females and 4 males with an average age of (60±10) years. The duration of high myopia was (33.33±6.61) years. The refractive power was (-23.32±5.95) D, and the axial length was (33.04±2.63) mm. The recession mount of medial rectus was (7.2±2.1) mm (4.0-10.0 mm) intraoperatively. At 6 months, the median esotropia improved from 130 (80-140) prism diopter (PD) to 0 (0-10) PD, and the hypotropia from 20 (15-25) PD to 0 (0-5) PD. The median abduction limitation decreased from -3 (-4--1) to -1 (-2-0), and the median limitation of elevation decreased from -2 (-4--1) to 0 (-1-0). The angle of esotropia and hypotropia significantly improved (Z=-2.67, -2.70; P=0.008, 0.007), and the restriction of abduction and elevation decreased (Z=-3.35, -3.24; both P=0.001). Only 3 patients' CT images were enrolled in a comparative study. Preoperative orbital CT scans showed inferior LR displacement and medial SR displacement with the posterior portion of the eyeball to the superotemporal quadrant of the orbit. After surgery, the mean reduction ratio of dislocation degree of the 3 patients was 28.97%, the dislocation of LR and SR was reduced, and the posterior global part was correctly positioned within the orbit. Conclusions: The modified Yokoyama's surgery combined with medial rectus muscle recession can effectively correct high myopic strabismus fixus, recover the eyeball anatomical position, and evidently improve eye mobility. The clinical effects are satisfactory. (Chin J Ophthalmol, 2019, 55: 670-676).

Abstract
OBJECTIVE To develop a simple, sensitive and robust method for rapid detection of human apurinic/apyrimidinic endonuclease 1 (APE1) in various biological samples. METHODS An abasic site-containing DNA probe with a sequence of 5'-T*T*C*C*T*C*T(ROX)AGAGXCGTT (BHQ2)C*A*C*T*G*T*AGTTTATA*C*A*G*T*GAATCTCTCTAG*T*C*T-3' ["X" represents AP site; The phosphorothioated nucleotides (at 3' side) are indicated with an asterisk after the nucleotides; ROX is 6-carboxy-X-rhodamine and BHQ2 is Black Hole quencher 2] was synthesized and used for the detection. In the presence of APE1, the DNA probe could be specifically hydrolyzed by the enzyme and release the fluorophore, resulting in strong fluorescence emission. The activity of APE1 was determined according to the rate of increase in fluorescence intensity. In this work, we modified the reaction buffer and significantly improved the performance of the method. Moreover, the method was further extended to measure the contents of APE1 in the protein extraction from peripheral blood mononuclear cells (PBMCs) extracted from human whole blood samples by density gradient centrifugation. The assay was also applied to measure the activity of APE1 in human serum samples. RESULTS With a new reaction buffer composed of 0.04% (V/V) Triton X-100, 50 mmol/L KAc, 20 mmol/L Tris-Ac, 10 mmol/L Mg(Ac)2 and 1 mmol/L dithiothreitol (DTT), the method achieved a detection limit of 0.005 U/mL (3 pg/mL) and a linear response ranging from 6 pg/mL to 1.2 ng/mL. The contents of APE1 in the protein extraction from PBMCs of eight blood samples were measured to be in the range from 0.061 to 0.40 ng/μg protein, with an average of 0.16 ng/μg protein. The recovery was 98%±5% (n=3). The levels of APE1 in the sera from 102 normal individuals (51 male and 51 female, age range: 59-75 years) were observed to be from 0.13 to 0.34 ng/mL, with a recovery of 96%±15% (n=3). CONCLUSION The new fluorescence assay was simple, rapid and sensitive, providing a practical tool to measure the activity of APE1 in serum samples and cell extracts. It also holds great potential in measurement of APE1 in many other biological samples for clinical test and laboratory research.

Abstract
Objective: To investigate the role of microRNA-29b-3p (miRNA-29b-3p) and miRNA-34c-3p in the process of pulmonary fibrosis, we detected the expression levels of miRNA-29b-3p and miRNA-34c-3p in the lung tissue of rats exposed to silica and A549 cells. Methods: SPF male Wistar rats were randomly divided into 1, 7, 14, 21, 28 d control group and silica (SiO(2)) dusting group, with 6 rats in each group. One-time non-exposure method was used to infuse 1ml SiO(2) suspension. The rat SiO(2) dusting group was established in the liquid, and the control rats were intratracheally injected with 1 ml of sterile physiological saline in the same manner. The lung tissues of each group were collected at the corresponding time points after dusting. Three of the rats were taken out for pathological observation, and the other three were used to screen differentially expressed miRNAs in lung tissue by miRNA microarray technology. A549 cells were cultured at the in vitro cell level and divided into control group, SiO(2) stimulation group and TGF-β(1) stimulation group, and cells were collected at 12, 24 and 48 h after treatment. The expression levels of miRNA-29b-3p and miRNA-34c-3p in rat lung tissue and A549 cells were verified by real-time PCR (qRT-PCR), target gene prediction of miRNA-29b-3p and miRNA-34c-3p and perform GO enrichment analysis and KEGG pathway analysis. Results: The weight growth rate of the control group was significantly higher than that of the SiO(2) dusting group. Compared with the control group, the lung mass and lung coefficient of the SiO(2) dusting group were significantly increased (P<0.05). The inflammatory response of the lungs in the control group was significantly reduced at 21 and 28 days, and the inflammatory cells infiltrated in the lung tissue of the SiO2 group. The rats in the control group had a small amount of collagen at 21 and 28 days. A large amount of collagen fiber deposition began to appear in the lung tissue of rats exposed to SiO(2) for 21 days. Compared with the control group, the expression levels of miRNA-29b-3p and miRNA-34c-3p in the SiO(2) dusting group were significantly down-regulated, and there was significant difference compared with the control group (P<0.05). The expression levels of miRNA-29b-3p and miRNA-34c-3p in A549 cells treated with SiO(2) and human recombinant TGF-β1 were significantly lower than those in the control group at 24 h and 48 h, and the difference was statistically significant (P<0.05). Conclusion: Down-regulation of miRNA-29b-3p and miR-34c-3p in rat lung tissue A549 cells may be associated with the development of early silicosis and is expected to be an indicator of early silicosis diagnosis and prognosis.

Abstract
Objective: To screen the changes of microRNA (miRNA) expression profiles in lung tissues of early silicosis rats, and provide a basis for functional analysis of differential microRNA. Methods: SPF Wistar male rats were randomly divided into a negative control group and SiO(2)-exposed groups, with 30 rats in each group. The model of silicosis in rats was established by intratracheal instillation of 1 ml SiO(2) suspension, and the control rats were treated with 1mL in the same way to sterilize normal saline. The lung tissues of two group were collected at the 1, 7, 14, 21, 28 d after SiO(2)-exposed. Three of the rat lung tissues were used for pathological observation, and the other three were used to screen differentially expressed miRNAs in lung tissue by miRNA microarray technology. miRNA chip screening and RT-qPCR were used to verify the expression levels of miRNA-423-5p and miRNA-26a-5p in the two groups. miRNA-423-5p and miRNA-26a-5p are predicted by target genes and analyzed by GO (gene ontology) enrichment analysis and KEGG (kyoto encyclopedia of genes and genomes) pathway analysis. Results: In the control group, the inflammatory response of lung tissue 21 and 28 days was significantly reduced compared with 1, 7 and 14 days, and the inflammatory cells infiltrated in the lung tissue of the SiO(2)-exposed rats. The rats in the control group had a small amount of collagen at 21 and 28 days, but a large amount of collagen fiber deposition began to appear in the lung tissue of rats exposed to SiO(2) after 21 days. Compared with the control group, the expression levels of micro RNA-423-5p was significantly up-regulated and the expression of microRNA-26a-5p was significantly down-regulated in the SiO(2)-exposed rats lung tissues dust at different time points (P<0.05) . Conclusion: The up-regulation of miRNA-423-5p and the down-regulation of miRNA-26a-5p in lung tissues of early silicotic rats may be related to the occurrence and development of early silicosis.

Abstract
Objective: Investigate the causes of poor prognosis of mechanical thrombectomy in the time window of acute ischemic stroke (AIS) with anterior circulation. Methods: A retrospective analysis was made on the data of 78 patients with anterior circulation AIS who underwent mechanical thrombectomy in the time window from January 2017 to December 2017 in the Department of Vascular Neurosurgery of Liaocheng Brain Hospital. The modified Rankin scale (mRS) was used to evaluate the prognosis of the patients 3 months after operation. According to the prognosis,the patients were divided into the group with good prognosis (42 cases, mRS<2 points) and the group with poor prognosis (36 cases, mRS<3 points). Univariate and multivariate Logistic regression analysis was used to analyze the related factors of poor prognosis. Results: (1) Univariate analysis showed that the prognosis of patients with good combination and primary stenosis of diabetes mellitus and atherosclerosis was lower than that of patients with poor prognosis (P<0.05). The collateral circulation compensation rate and vascular recanalization rate of patients with good prognosis were higher than those of patients with poor prognosis (P<0.05). Learning significance (P<0.05). (2) Multivariate analysis showed that diabetes mellitus (P=0.035), collateral circulation compensation (P=0.011) and primary atherosclerotic stenosis (P=0.042) were independent risk factors for poor prognosis. Conclusion: Perfect preoperative evaluation and strict screening of patients, good collateral circulation compensation,individualized treatment for patients with primary atherosclerotic stenosis,and strict control of postoperative hyperglycemia can improve the clinical prognosis of endovascular therapy.

Abstract
Objective: To evaluate the clinical features of retrocorneal fungal infection and the therapeutic effects. Methods: This was a retrospective, noncomparative study of nine patients with retrocorneal fungal infection and an intact corneal epithelium treated at Qingdao Eye Hospital. The history, clinical features, diagnostic methods, pathogens and therapeutic effects were analyzed. Results: Five patients had a history of trauma by plant, two had a non-plant injury, and two had unidentified reasons. The duration between the initial onset and the first visit to our hospital was 7.9 months (range, 3 months to 2 years). There was endothelial plaque and sometimes with white infiltration in the deep stroma, but the corneal epithelium remained integrated, and the anterior stroma was uninfected. The patients were misdiagnosed as uveitis, herpes simplex keratitis or bacterial keratitis in the other hospitals. Visual acuity was 20/200 in four eyes, 20/60 in one eye, 20/40 in two eyes, and 20/30 in two eyes. Fungal hyphae were detected by confocal microscopy in six eyes. All the eyes had poor response to the antifungal medication before penetrating keratoplasty was performed. The smear examinations of the corneal endothelial plaque showed fungal hyphae in six eyes. Alternaria Nees, Apospory, Phialophora verrucosa, and Fusarium were identified. Conclusions: Plant injury is the most common risk factor of retrocorneal fungal infection. Slow onset and no initially obvious symptoms may lead to delayed diagnosis and misdiagnosis. The diagnosis can be confirmed by confocal microscopy before surgery. The effect of antifungal medication is usually poor. (Chin J Ophthalmol, 2017, 53:758-765).

Abstract
Objective: We aimed to examine the feasibility and toxicity of EC-T dose-dense regimen and to demonstrate the suitable dose of epirubicin in a Chinese early-stage breast cancer population with high recurrence risk. Methods: 370 patients with early-stage breast cancer at high risk of recurrence were treated with EC-T dose-dense adjuvant chemotherapy and prophylactic administration of recombinant human granulocyte stimulating factor (G-CSF). The incidence of delayed chemotherapy, drug reduction and adverse reactions were retrospectively analyzed. Results: 370 patients completed the planned eight cycles of chemotherapy, 50 patients experienced chemotherapy delay, and 90 had chemotherapy dose reductions. Overall, 61.1% of the patients experienced grade 3 or 4 hematology toxicities, 4.1% of the patients experienced grade 3 gastrointestinal toxicity, 16.3% experienced grade 3 or 4 liver malfunction, and 1.9% experienced grade 3 alopecia. In the multivariate analysis, pretreatment epirubicin levels were associated with comprehensive and hematology toxicity risk (OR=1.268, P=0.046; OR=1.244, P=0.036). With G-CSF support, the probability of grade 3-4 dose limiting toxicity, i. e. neutropenia, abnormal liver function, and gastrointestinal adverse effects did not increase as the epirubicin dose level increased(P>0.05). However, there were no statistically significant associations between epirubicin grade and treatment delay (P=0.814) or dose reduction (P=0.282). Conclusions: EC-T dose-dense chemotherapy shows tolerable toxicity. High dose level is not a limiting factor for this regimen. With G-CSF support, epirubicin 85-90 mg/m(2) is appropriate tolerance dose for Chinese early breast cancer patients with high recurrence risk.

Abstract
Most osteoporotic fractures occur at metaphyseal regions of long bones. The present study proposed a clinically relevant animal model that satisfied: i) induction of osteoporosis, ii) unilateral complete osteotomy at metaphysis, iii) internal fixation. 6 months old female Sprague-Dawley rats (n = 64) were randomly divided into the ovariectomised-metaphyseal osteotomy (OVX, n = 32) and metaphyseal osteotomy (SHAM, n = 32) groups. The metaphyseal-osteotomy model was created with a plate-fixation of the osteotomy and assessed by X-ray, micro-computed tomography, histomorphometry and mechanical testing at weeks 1, 3 and 6. X-ray results showed complete healing of metaphyseal osteotomy at week 6. Histology showed 3 stages of metaphyseal healing. Stage 1 was characterised by fibrous tissue, consisting of disorganised orientation of collagen fibres, and infiltration of immune cells. At stage 2, a transitional zone consisting of maturing fibrous tissue and differentiating mesenchymal cells with early trabecular bone formation and disorganised woven bone were observed. During stage 3, cortical bone ends unified and woven bone underwent transformation to lamellar bone. OVX group healing was significantly delayed when compared to SHAM samples. The study demonstrated that healing of osteoporotic osteotomy at the metaphyseal region was delayed in terms of radiography, histomorphometry and mechanical strength. These quantitative evaluations, along with histological features, may provide key references for future studies. The animal model may provide additional clinical relevance as most osteoporotic fracture in humans occurs at metaphyseal regions.
