Abstract
Objective: To investigate the clinical application of EWSR1 gene rearrangement by fluorescence in situ hybridization (FISH) in bone and soft tissue tumors and to analyze the cases with atypical signal pattern. Methods: The cases detected for EWSR1 gene rearrangement by FISH in Beijing Jishuitan Hospital, Capital Medical University from 2014 to 2021 were collected, and the value of detecting EWSR1 gene rearrangement for diagnosing bone and soft tissue tumors was analyzed. The cases with atypical positive signals were further analyzed by next generation sequencing (NGS). Results: FISH using EWSR1 break-apart probe kit was successfully performed in 97% (205/211) of cases, 6 cases failed. Four of the 6 failures were due to improper decalcification, 1 case due to signal overlap caused by thick slices, and 1 case due to signal amplification and disorder. EWSR1 gene rearrangements were positive in 122 cases (122/205, 59%), atypical positive signal in 8 cases (8/205, 4%), and negative in 75 cases (75/205, 37%). In cases testing positive, the percentage of positive cells ranged from 34% to 98%, with 120 cases (120/122, 98%) showing a positive cell percentage greater than 50%. Among the 205 successfully tested cases, 156 cases were histologically diagnosed as Ewing's sarcoma, of which 110 were positive (110/156, 71%), 7 were atypical positive (7/156, 4%), and 39 were negative (39/156, 25%). Nine cases were histologically diagnosed as clear cell sarcoma of soft tissue, of which 6 were positive (6/9), 1 was atypical positive (1/9), and 2 were negative (2/9). Five cases were histologically diagnosed as extraskeletal myxoid chondrosarcoma, of which 2 were positive (2/5) and 3 were negative (3/5). Three cases were histologically diagnosed as angiomatoid fibrous histiocytoma, of which 2 were positive (2/3) and 1 was negative (1/3). Two cases were histologically diagnosed as myoepithelioma of soft tissue, of which 1 was positive (1/2) and 1 was negative (1/2). One case was histologically diagnosed as olfactory neuroblastoma with a positive result. The 29 other tumor cases including osteosarcoma, synovial sarcoma, and malignant melanoma and others were all negative. Basing on histology as the standard for diagnosis and considering atypical positive cases as negative, comparing with the 29 cases of other tumors as control group, the sensitivity for diagnosing Ewing's sarcoma through the detection of EWSR1 gene rearrangement was 71%, and the specificity was 100%; the sensitivity for diagnosing clear cell sarcoma of soft tissue was 67%, and the specificity was 100%; the sensitivity for diagnosing extraskeletal myxoid chondrosarcoma was 40%, and the specificity was 100%; the sensitivity for diagnosing angiomatoid fibrous histiocytoma was 67%, and the specificity was 100%; the sensitivity for diagnosing myoepithelioma of soft tissue was 50%, and the specificity was 100%; the sensitivity for diagnosing olfactory neuroblastoma was 100%, and the specificity was 100%. Four of 8 cases with atypical positive signals analyzed by NGS showed EWSR1 rearrangement, including EWSR1::FLI1 in one case of Ewing sarcoma, EWSR1::NFATC2 in one case of EWSR1::NFATC2-rearranged sarcoma, EWSR1::ATF1 in one case of clear cell sarcoma of soft tissue and EWSR1::NR4A3 in one case of extraskeletal myxoid chondrosarcoma. Conclusions: Detection of EWSR1 rearrangement by FISH is of utmost significance in the diagnosis of bone and soft tissue tumors. Cases with atypical positive signals should be further scrutinized, correlating with their histomorphology and verifying by NGS if necessary.

Abstract
Objective: To establish prediction models for human leukocyte antigen (HLA) haplotypes and HLA genotypes, and verify the prediction accuracy. Methods: The prediction models were established based on the characteristic of HLA haplotype inheritance and linkage disequilibrium (LD), as well as the invention patents and software copyrights obtained. The models include algorithm and reference databases such as HLA A-C-B-DRB1-DQB1 high-resolution haplotypes database, B-C and DRB1-DQB1 LD database, G group alleles table, and NMDP Code alleles table. The prediction algorithm involves data processing, comparison with reference data, filtering results, probability calculation and ranking, confidence degree estimation, and output of prediction results. The accuracy of the predictions was verified by comparing them with the correct results, and the relationship between prediction accuracy and the probability distribution and confidence degree of the predicted results was analyzed. Results: The HLA haplotypes and genotypes prediction models were established. The prediction algorithm included the prediction of A-C-B-DRB1-DQB1 haplotypes according to HLA-A, B, DRB1, C, DQB1 genotypes, the prediction of C and DQB1 high-resolution results according to A, B and DRB1 high-resolution results, and the prediction of A, B, DRB1, C and DQB1 high resolution results according to the A, B and DRB1 intermediate or low resolution results. Validation results of "Predicting A-C-B-DRB1-DQB1 haplotypes basing on HLA-A, B, DRB1, C, DQB1 genotypes" model: for 787 data, the accuracy was 94.0% (740/787) with 740 correct predictions, 34 incorrect predictions, and 13 instances with no predicted results. For 847 data, the accuracy was 100% (847/847). The 2 411 and 2 594 haplotype combinations predicted from 787 and 847 data were grouped according to confidence degree, the accuracy was 100% (48/48, 114/114) for a confidence degree of 1, 96.2% (303/315) and 97.8% (409/418) for a confidence degree of 2 respectively. Validation results of "Predicting A, B, DRB1 and C, DQB1 high-resolution genotypes basing on HLA-A, B, DRB1 high, intermediate, or low resolution genotypes" model: when predicting C and DQB1 high resolution genotypes basing on A, B, and DRB1 high resolution genotypes, 89.3% (1 459/1 634) of the predictions were correct. The accuracy for the top 2 predicted probability (GPP) ranking was 79.2% (1 156/1 459), and for the top 10, it was 95.0% (1 386/1 459). Furthermore, when GPP≥90% and GPP 50%-90%, the prediction accuracy was 81.3% (209/257) and 72.8% (447/614) respectively. The accuracy of predicting C and DQB1 high resolution genotypes basing on the results of A, B, and DRB1 high resolution genotypes from the China Marrow Donor Program was 87.0% (20/23). The accuracy of predicting A, B, DRB1, C, and DQB1 high resolution genotypes basing on the results of A, B, and DRB1 intermediate or low-resolution genotypes was 70.0% (7/10) and 52.5% (21/40) respectively. When predicting whether the patient is likely to have a HLA 10/10 matched donor, the accuracy of the top 2 GPP combinations with a proportion of ≥50% was 85.7% (6/7). Conclusions: When using A, B, DRB1, C, DQB1 genotypes to predict A-C-B-DRB1-DQB1 haplotype combinations, the results with a confidence degree of 1 and 2 are reliable. When predicting C and DQB1 genotypes according to A, B and DRB1 genotypes, the top 10 results ranked by GPP are reliable, and the top 2 results with GPP≥50% are more reliable.

Abstract
Objective: To explore the possible anti-atherosclerotic mechanisms of glucose co-transporter-2 inhibitor canagliflozin. Methods: ApoE-/-mice fed on Western diet were randomly assigned into the model group (n=10) and the canagliflozin group (n=10). C57BL/6J mice fed on normal diet were chosen as the control group (n=10). Mice in the canagliflozin group were gavaged with canagliflozin for 14 weeks. The presence and severity of atherosclerosis were evaluated with HE and oil red O stainings in aortic root section slices. PCR assay was performed to determine the mRNA expression levels of nitric oxide synthase. Hepatic transcriptome analysis and hepatic amino acid detection were conducted using RNA-seq and targeted LC-MS, respectively. Results: HE staining and oil red O staining of the aortic root showed that AS models were successfully established in ApoE-/-mice fed on Western diet for 14 weeks. Canagliflozin alleviated the severity of atherosclerosis in pathology. Hepatic transcriptome analysis indicated that canagliflozin impacted on amino acid metabolism, especially arginine synthesis in ApoE-/-mice. Targeted metabolomics analysis of amino acids showed that canagliflozin reduced hepatic levels of L-serine, L-aspartic acid, tyrosine, L-hydroxyproline, and L-citrulline, but raised the hepatic level of L-arginine. Compared to the model group, the canagliflozin group exhibited higher serum arginine and nitric oxide levels as well as elevated nitric oxide mRNA expression in aortic tissues (P<0.05). Conclusion: Canagliflozin regulated the amino acid metabolism, reduced the levels of glucogenic amino acids,and promoted the synthesis of arginine in atherosclerotic mice.

Abstract
The intertwining between spin, charge, and lattice degrees of freedom can give rise to unusual macroscopic quantum states, including high-temperature superconductivity and quantum anomalous Hall effects. Recently, a charge density wave (CDW) has been observed in the kagome antiferromagnet FeGe, indicative of possible intertwining physics. An outstanding question is that whether magnetic correlation is fundamental for the spontaneous spatial symmetry breaking orders. Here, utilizing elastic and high-resolution inelastic x-ray scattering, we observe a c-axis superlattice vector that coexists with the 2[Formula: see text]2[Formula: see text]1 CDW vectors in the kagome plane. Most interestingly, between the magnetic and CDW transition temperatures, the phonon dynamical structure factor shows a giant phonon-energy hardening and a substantial phonon linewidth broadening near the c-axis wavevectors, both signaling the spin-phonon coupling. By first principles and model calculations, we show that both the static spin polarization and dynamic spin excitations intertwine with the phonon to drive the spatial symmetry breaking in FeGe.

Abstract
The biological samples of oral genetic diseases and rare diseases are extremely precious. Collecting and preserving these biological samples are helpful to elucidate the mechanisms and improve the level of diagnose and treatment of oral genetic diseases and rare diseases. The standardized construction of biobanks for oral genetic diseases and rare diseases is important for achieving these goals. At present, there is very little information on the construction of these biobanks, and the standards or suggestions for the classification and coding of biological samples from oral and maxillofacial sources, and this is not conducive to the standardization and information construction of biobanks for special oral diseases. This consensus summarizes the background, necessity, principles, and key points of constructing the biobank for oral genetic diseases and rare diseases. On the base of the group standard "Classification and Coding for Human Biomaterial" (GB/T 39768-2021) issued by the National Technical Committee for Standardization of Biological Samples, we suggest 76 new coding numbers for different of biological samples from oral and maxillofacial sources. We hope the consensus may promote the standardization, and smartization on the biobank construction as well as the overall research level of oral genetic diseases and rare diseases in China.

Abstract
Objective: To investigate the effects of calorie-restricted diet (CRD), high protein diet (HPD), high protein, and high dietary fiber diet (HPD+HDF) on metabolic parameters and androgen level in overweight/obese patients with polycystic ovary syndrome(PCOS). Methods: Ninety overweight/obese patients with PCOS from Peking University First Hospital from October 2018 to February 2020 were given medical nutrition weight loss therapy for 8 weeks and were randomly divided into CRD group, HPD group, and HPD+HDF group, with 30 patients in each group. Body composition, insulin resistance, and androgen level were detected before and after weight loss, and the efficacy of three weight loss therapies was compared through variance analysis and Kruskal-Wallis H test. Results: Eight patients in CRD group quit because they could not strictly complete the follow-up, therefore at the end of weight loss, 22, 30, and 30 patients in CRD group, HPD group and HPD+HDF group, respectively, were included in the final analysis. The baseline ages of the three groups were (31±2) years, (32±5) years and (31±5) years, respectively (P=0.952). After weight loss, the relevant indicators in HPD group and HPD+HDF group decreased more than those in CRD group. The body weight of CRD group, HPD group and HPD+HDF group decreased by 4.20 (11.92, 1.80), 5.00 (5.10, 3.32) and 6.10 (8.10, 3.07) kg, respectively (P=0.038); BMI of the three groups decreased by 0.80 (1.70, 0.40), 0.90 (1.23, 0.50) and 2.20 (3.30, 1.12) kg/m2, respectively (P=0.002); homeostatic model assessment-insulin resistance(HOMA-IR) index decreased by 0.48(1.93, 0.05), 1.21(2.91, 0.18) and 1.22(1.75, 0.89), respectively (P=0.196); and free androgen index(FAI) decreased by 0.23(0.67, -0.04), 0.41(0.64, 0.30) and 0.44(0.63, 0.24), respectively (P=0.357). Conclusions: The three medical nutrition therapies can effectively reduce the weight of overweight/obese patients with PCOS, and improve insulin resistance and hyperandrogenism. Compared with CRD group, HPD group, and HPD+HDF group have better fat-reducing effect, and can better preserve muscle and basal metabolic rate while losing weight.

Abstract
Androgen excess is a common endocrine and metabolic problem in clinical practice, which affects the health of women throughout their life cycle. Usually, its diagnosis and treatment need multidisciplinary cooperation. The etiological diagnosis of female hyperandrogenism should be based on the etiological characteristics at different ages and should be comprehensively evaluated from medical history, physical examination, determination of androgen and other endocrine hormones, functional tests, imaging, and genetic testing, etc. The general principle of androgen excess cause diagnosis is first to determine whether the patient has clinical and/or biochemical androgen excess, then determine whether she conforms to the diagnostic criteria of polycystic ovary syndrome (PCOS), and then determine whether it is a specific disease or not. Finally, mass spectrometry should be adopted for verifying the androgen levels in those without clear causes found to exclude pseudo-elevation, thus it can be diagnosed as idiopathic androgen excess. Exploring the clinical pathway for the etiological diagnosis of female hyperandrogenism has important reference significance for guiding the standardized and accurate diagnosis and treatment of female hyperandrogenism.

Abstract
Yin Chan Quan Shu (Obstetrics and gynecology monograph) is a monograph on obstetrics and gynecology compiled by Wang Kentang in the Ming Dynasty. It had four volumes and was published in the thirtieth year of Wanli (1602) in the Ming Dynasty after it was edited by Zhang Shoukong and others. It was found that Yin Chan Quan Shu has four versions remaining. They were the version printed by Shu Lin Qiao Shan Tang in the Ming Dynasty, held in the National Library of China and the Cabinet Library of Japanese Official Documents Library; the version revised according to the version of Shu Lin Qiao Shan Tang, held in the Library of Capital Medical University, Tianjin Medical College, Shanghai Branch of the Chinese Medical Association, the Library of Guangzhou University of Chinese Medicine and the Cabinet Library of the National Archives of Japan; the version based on the version of Shu Lin Qiao Shan Tang in the Ming Dynasty, transcribed in the fourth year of Wen Hua (1807), collected in the Cabinet Library of the National Archives of Japan; the version transcribed according to the revised version in the Ming Dynasty, collected in the Shanghai Branch of the Chinese Medical Association. It was found that there was no evidence to support the existence of the so-called "version of Kangxi in the Qing Dynasty". This means almost all versions remaining came from the versions published in the Ming Dynasty. The references of Yin Chan Quan Shu came from Pulse Classic (Mai Jing), Chan Bao, Fu Ren Da Quan Liang Fang and other works with the supplement and development by Wang Kentang.Yin Chan Quan Shu was the main sources and foundation of the Criteria of Syndrome Identification and Treatment in Gynecology (Nv Ke Zheng Zhi Zhun Sheng) by Wang Kentang.

Abstract
Leaf stoichiometry can characterize plant ecological strategies and correlate with plant responses to climate change. The role of vascular epiphytes in the ecosystem processes of tropical and subtropical forest ecosystems cannot be ignored. Vascular epiphytes are very vulnerable to climate change, however, the relationship between the response of epiphytes to climate change and leaf stoichiometry is not well understood. We present data for 19 vascular epiphyte species that were collected during four consecutive censuses (in 2005, 2010, 2015, and 2020) over 15 years in a subtropical montane cloud forest. We assessed the relationships between the population dynamics and leaf stoichiometry of these vascular epiphytes. Experiencing an extreme drought, 14 of the 19 epiphyte species showed an obvious decrease in the number of individuals, and all species showed negative growth in the number of populations. Subsequently, the total number of individuals gradually recovered, increasing from 7,195 in 2010 to 10,121 in 2015, then to 13,667 in 2020. The increase in the number of vascular epiphyte individuals from 2010 to 2015 was significantly negatively correlated with leaf nitrogen and phosphorus concentration, and was significantly positively correlated with the leaf carbon-nitrogen ratio. Vascular epiphyte populations with higher leaf nutrient concentrations exhibited weaker resilience to the extreme drought, which demonstrated that a resource-conservative strategy was advantageous for the recovery of epiphyte populations. Our findings suggest that ecological stoichiometry can be a useful framework for forecasting the dynamics of vascular epiphyte populations in response to climate change.

Abstract
Objective: To investigate the diagnostic value of expression of CCNB3 and BCOR in BCOR-CCNB3 sarcoma (BCS). Methods: Fifteen cases of BCS confirmed by fluorescence in situ hybridization (FISH) and/or reverse transcription-polymerase chain reaction (RT-PCR) from January 2014 to October 2021 at Beijing Jishuitan Hospital were collected. Immunohistochemical EnVision method was used to detect the expression of CCNB3 and BCOR in 15 cases of BCS and in 65 non-BCS tumors (54 cases of Ewing's sarcoma, 5 cases of CIC rearranged sarcoma, 4 cases of synovial sarcoma, 1 case of mesenchymal chondrosarcoma and 1 case of soft tissue clear cell sarcoma). Results: Immunohistochemical staining for CCNB3 revealed strongly diffuse nuclear staining in 14 of 15 (14/15) BCS cases, whereas none of the 65 non-BCS tumors showed any staining. Immunohistochemical staining for BCOR showed strongly diffuse nuclear staining in 11 (11/14) BCS cases; seven of the 65 (7/65, 10.8%) non-BCS tumors showed variable staining (five cases of Ewing sarcoma, one cases of synovial sarcoma, and one case of mesenchymal chondrosarcoma). The sensitivity and specificity of CCNB3 in diagnosing BCS were 93.3% and 100% and these of BCOR were 78.6% and 89.2%, respectively. Conclusions: CCNB3 is a highly sensitive and specific marker for BCS.The antibody may help screening BCS.

Abstract
Objective: To construct a diagnostic and predictive model for chronic obstructive pulmonary disease complicated with pulmonary hypertension (COPD-PH) and evaluate its effect. Methods: A total of 1 514 COPD patients treated in 5 hospitals from January 1, 2014 to December 31, 2019 were retrospectively collected and divided into training cohort (1 072 cases) and validation cohort (442 cases) according to the ratio of 7∶3 according to the inclusion time. Data including demographic data, smoking status, history of disease, and clinical examination were collected through patient medical records and electronic medical record systems. Multivariate logistic regression models were used to explore the related factors of COPD-PH, and the nomogram model was constructed using the "rms" program package. The calibration curve was used to evaluate the consistency between the prediction probability of the model and the actual results. The C index and the area under the receiver operating characteristic curve (ROC) were used to evaluate the discrimination of the model. The decision curve analysis (DCA) was used to evaluate the clinical practicability of the model. Results: In the training cohort, 3.7%, 15.2% and 81.1% were aged 50-59, 60-69 and ≥70 years, respectively, which were significantly different from the age composition of the validation cohort (7.9%, 27.8% and 64.3%, respectively) (P=0.041). There was no significant difference between the training cohort (79.4%) and the validation cohort (84.6%) (P=0.243). Multivariate logistic regression analysis of the training cohort showed that age ≥70 years [OR (95%CI): 3.32 (1.49-7.36)] and smoking status [former (current) smoking, OR (95%CI)] were 3.67 (2.51-5.37) and 2.04 (1.44-2.90), respectively], NT-probNP≥1 400 ng/L[OR (95%CI): 9.88 (6.23-15.66)], right atrial diameter [OR (95%CI): 1.11 (1.07-1.15)] was COPD-related factors of PH, based on the above factors-PH nomogram COPD model was set up and develop for online tools (https://ph-666.shinyapps.io/zhonghua-PH/). The calibrated C index (95%CI) of the training cohort and the validation cohort were 0.82 (0.77-0.87) and 0.77 (0.68-0.86), respectively. The calibration curve was close to the diagonal in both the training cohort and the validation cohort. The AUC (95%CI) of the nomogram model was 0.82 (0.80-0.85) in the training cohort and 0.77 (0.73-0.82) in the validation cohort. ROC curve showed that the optimal threshold in the training cohort was 0.60, and the sensitivity and specificity under this value were 0.74 and 0.78, respectively; the optimal threshold for the validation cohort was 0.70, and the sensitivity and specificity under this value were 0.76 and 0.65, respectively. DCA analysis showed that the nomogram model provided better net benefits than the all-variable selection and no-variable selection strategies with threshold probabilities greater than 15.0% and 13.0% in the training and validation cohorts, respectively. Conclusions: The nomogram model for the diagnosis and prediction of COPD-PH is simple and accurate, which has a good clinical application prospect.

Abstract
Objective: To understand the spatial characteristics of echinococcosis and associated factors in the pastoral area of Qinghai province, and provide evidence for the effective prevention and control of echinococcosis. Methods: The number of echinococcosis cases in the pastoral areas of Qinghai in 2019 was collected to perform spatial epidemiological analysis. The thematic map of the distribution of echinococcosis cases was generated with software ArcGIS 10.8 for visual analysis and spatial autocorrelation analysis. The spatial autocorrelation and spatial scanning analysis were performed to estimate the clustering of echinococcosis with software SaTScan 9.5. Software GeoDa 1.14 and ArcGIS 10.8 were used to establish spatial lag model and geographical weighted regression model to analyze the related factors of echinococcosis epidemic. Results: In 2019, the echinococcosis surveillance covered 64 741 people in the pastoral area of Qinghai, and 829 echinococcosis cases were found, with a prevalence rate of 1.28%. The distribution of the cases had spatial correlation (Moran's I=0.41, P<0.001). The most possible clustering areas indicated by spatial scanning analysis included Banma, Jiuzhi, Dari and Gande counties of Guoluo Tibetan Autonomous Prefecture (LLR=460.77, RR=9.20, P<0.001). The prevalence of echinococcosis in the pastoral areas was positively associated with the total annual precipitation (β=0.13, P=0.036), and negatively associated with population density (β=-1.36, P=0.019) and doctors/nurse ratio (β=-25.60, P=0.026). Conclusions: The distribution of echinococcosis cases in the pastoral areas of Qinghai in 2019 had spatial correlation, and the prevalence was affected by total annual precipitation, population density, and doctors/nurse ratio.

Abstract
Chronic thrombotic pulmonary hypertension (CTEPH) is a rare progressive pulmonary vascular disease, which is classified as World Health Organization (WHO) functional class Ⅳ pulmonary arterial hypertension (PAH). The diagnosis was based on mean pulmonary arterial pressure ≥25 mmHg(1 mmHg=0.133 kPa) and pulmonary arterial wedge pressure ≤15 mmHg measured by right heart catheterization, with the under-utilization of radionuclide ventilation/perfusion scan and regular anticoagulation therapy for at least three months. The incidence of CTEPH is low, at 4 cases per million population per year. Despite the in-depth research on CTEPH in recent years, the strengthening of clinical diagnostic awareness, and the emergence of treatment methods such as pulmonary endarterectomy (PEA) and balloon pulmonary angioplasty (BPA), the prognosis of CTEPH patients has been dramatically improved. However, the pathogenesis of CTEPH is unclear, and the lack of effective early diagnostic methods has become a bottleneck limiting the improvement of clinical diagnosis and treatment. In this paper, we reviewed the current research progress on the pathogenesis of CTEPH to increase the understanding of CTPTH disease.

Abstract
Objective: To investigate the clinical features and the value of different diagnostic indices for etiology in reproductive age women with hyperandrogenism. Methods: The medical records of 96 reproductive age women with hyperandrogenism in the multi-disciplinary team of Peking University First Hospital from January 2020 to April 2021 were collected. The patients were divided into four groups based on final diagnosis: congenital adrenal hyperplasia (CAH) (n=8), polycystic ovary syndrome (PCOS) (n=67), idiopathic hyperandrogenism (n=13) and other specific diseases (n=8), respectively. The indices related to androgens in different groups were compared, and then their efficiency for diagnosis of CAH and PCOS were analyzed with receiver operator characteristic curve (ROC curve). Results: A total of 96 patients with hyperandrogenism were recruited, with the age of 19-45 (29±6) years old. Overall, 4.2% (4/96) of the patients were with single clinical hyperandrogenism, 56.3% (54/96) were with single laboratory hyperandrogenaemia and 39.6% (38/96) were with both. The breakdown into laboratory hyperandrogenaemia subtypes was as follows: only T elevation 22.8% (21/92), only A2 elevation 7.6% (7/92), none DHEAS elevation, only FAI elevation 5.4% (5/92) and elevation of more than one of the androgen indices mentioned above accounted for 64.1% (59/92). In the reasons of consultation, simple irregular menstruation (36.0%, 32/89) or accompanied by clinical hyperandrogenism with or without infertility (36.0%, 32/89) were the most common. As for primary visiting departments, Obstetrics and Gynecology accounted for 53.2% (51/96), and then Endocrinology as 39.5% (38/96). The 17-OHP level of CAH, PCOS and idiopathic hyperandrogenism group was 20.0 (8.2, 33.1), 1.1 (0.8, 1.4), 0.9 (0.8, 1.3) ng/ml, respectively. The androstenedione level in these groups was 6.3 (4.6, 8.7), 3.8 (2.9, 4.8) and 3.2 (2.7, 3.7) ng/ml, respectively. The 17-OHP and androstenedione levels of CAH group were significantly higher than that in PCOS or idiopathic hyperandrogenism group (all P<0.05). The ratio of LH and FSH in these three groups was 0.8(0.5, 1.0), 1.3(0.6, 1.9) and 0.6(0.3, 0.7), respectively. The ratio of LH and FSH was significantly higher in PCOS than that in idiopathic hyperandrogenism group (P=0.024), but yet there was no significant difference compared with CAH group (P>0.05). The AUC of ROC curve of 17-OHP for CAH diagnosis was 0.94, followed by androstenedione 0.83, whereas LH/FSH for PCOS diagnosis was only 0.63. Conclusions: Among the reasons of consultation in reproductive age women who visited our multi-disciplinary team for female hyperandrogenism, simple irregular menstruation or accompanied by clinical hyperandrogenism with or without infertility are the most common. PCOS accounts for the majority of different androgen excess disorders. 17-OHP is the most valuable parameter for the diagnosis of CAH and secondly androstenedione.

Abstract
Objective: To analyze the pathogenic bacteria and epidemiological characteristics in children with respiratory tract infection in Tianjin area. Methods: Retrospective case analysis was performed on 2 392 hospitalized children in the wards of respiratory diseases, intensive care unit and special care ward of Tianjin Children's Hospital from June 2018 to May 2019. Thirteen pathogenic bacteria in deep sputum and bronchoalveolar lavage fluid samples were detected by loop-mediated isothermal amplification. The laboratory data and clinical characteristics of the infected children were analyzed, and the comparison between groups was performed by t test or χ2 test. Results: Among 2 392 cases, 1 407 were males and 985 females. There was no significant difference in the detection rate between males and females (72.5% (1 020/1 407) vs.74.2% (731/985), χ2=0.87, P=0.35). A total of 1 751 strains and 12 kinds of positive respiratory pathogens were detected, with a detection rate of 73.2%. Among them, 913 (38.2%) strains were Mycoplasma pneumoniae (MP), 514 (21.5%) were Streptococcus pneumoniae (Sp), 381 (15.9%) were Methicillin-resistant Staphylococcus aureus (MRSA) and 279 (11.7%) were Hemophilus influenzae (Hi). There was significant difference in the detection rate of pathogens among different age groups (χ²=83.67, P<0.01). The positive rate of alveolar lavage fluid group was higher than that of deep sputum fluid group [81.6% (614/752) vs. 69.3% (1 137/1 640), χ2=39.89, P<0.01]. The length of hospital stay of children infected with different pathogens was significantly different (all P<0.01). There was significant difference in duration of fever among children infected with different pathogens (χ²=228.69,103.56, 3.96, 27.38,24.50,41.66, all P<0.05). There were 63 (7.7%) cases of atelectasis, 260 (31.9%) cases of pleurisy and 120 (14.7%) cases of pleural effusion in MP children. Children with Sma were most likely to involve the heart system (2/9), and children with Eco infection had a higher incidence of complications such as those of blood (3/19), urinary (2/19), digestive systems(4/19), systemic inflammatory response syndrome and sepsis (1/19). Conclusions: The main bacterial pathogens of respiratory tract infection in children in Tianjin were MP, Sp, MRSA and Hi. It is suggested that clinicians should not only pay attention to the respiratory symptoms of children, but also pay attention to the complications caused by bacterial pathogen infection, so as to prevent the deterioration of the disease and improve the prognosis.

Abstract
The Kitaev quantum spin liquid epitomizes an entangled topological state, for which two flavors of fractionalized low-energy excitations are predicted: the itinerant Majorana fermion and the Z2 gauge flux. It was proposed recently that fingerprints of fractional excitations are encoded in the phonon spectra of Kitaev quantum spin liquids through a novel fractional-excitation-phonon coupling. Here, we detect anomalous phonon effects in α-RuCl3 using inelastic X-ray scattering with meV resolution. At high temperature, we discover interlaced optical phonons intercepting a transverse acoustic phonon between 3 and 7 meV. Upon decreasing temperature, the optical phonons display a large intensity enhancement near the Kitaev energy, JK~8 meV, that coincides with a giant acoustic phonon softening near the Z2 gauge flux energy scale. These phonon anomalies signify the coupling of phonon and Kitaev magnetic excitations in α-RuCl3 and demonstrates a proof-of-principle method to detect anomalous excitations in topological quantum materials.

Abstract
Objective: To compare the efficacy and safety of Changsulin® with Lantus® in treating patients with type 2 diabetes mellitus (T2DM). Methods: This was a phase Ⅲ, multicenter, randomized, open-label, parallel-group, active-controlled clinical trial. A total of 578 participants with T2DM inadequately controlled on oral hypoglycemic agents were randomized 3∶1 to Changsulin® or Lantus® treatment for 24 weeks. The efficacy measures included changes in glycosylated hemoglobin (HbA1c), fasting plasma glucose (FPG), 2h postprandial plasma glucose (2hPG), 8-point self-monitoring of blood glucose (SMBG) profiles from baseline, and proportions of subjects achieving targets of HbA1c and FPG. The safety outcomes included rates of hypoglycemia, adverse events (AEs) and anti-insulin glargine antibody. Results: After 24 weeks of treatment, mean HbAlc decreased 1.16% and 1.25%, FPG decreased 3.05 mmol/L and 2.90 mmol/L, 2hPG decreased 2.49 mmol/L and 2.38 mmol/L in Changsulin® and in Lantus®, respectively. No significant differences could be viewed in above parameters between the two groups (all P>0.05). There were also no significant differences between Changsulin® and Lantus® in 8-point SMBG profiles from baseline and proportions of subjects achieving the targets of HbA1c and FPG (all P>0.05). The rates of total hypoglycemia (38.00% and 39.01% for Changsulin® and Lantus®, respectively) and nocturnal hypoglycemia (17.25% and 16.31% for Changsulin® and Lantus®, respectively) were similar between the two groups (all P>0.05). Most of the hypoglycemia events were asymptomatic, and no severe hypoglycemia were found in both groups. No differences were observed in rates of AEs (61.77% vs.52.48%) and anti-insulin glargine antibody (after 24 weeks of treatment, 6.91% vs.3.65%) between the two groups (all P>0.05). Conclusions: Changsulin® shows similar efficacy and safety profiles compared with Lantus® and Changsulin® treatment was well tolerated in patients with T2DM.

Abstract
Objective: To explore the progress of small shadow and the change of lung function in pneumoconiosis with positive autoantibody, so as to provide basis for clinical treatment of pneumoconiosis. Methods: A total of 756 patients were admitted to the pneumoconiosis department of the Guangzhou Occupational Disease Prevention Hospital from January 1, 2013 to June 1, 2019. The patients with combined infection were excluded. According to whether the autoantibody was positive, they were divided into positive group and negative group, 25 cases in each group. Follow-up observation of X-ray chest radiographs, chest CT, forced expiratory volume in one second (FEV(1)) and forced expired flow at 50% of FVC (MEF(50)) of pneumoconiosis patients for 5 years, to analyze the influence of positive autoantibody on the morphology of X-ray chest film, the pneumoconiosis promotion in 5 years and lung function. Results: There were 22 males and 3 females in the autoantibody positive group, aged 53.14±10.51 years. In the autoantibody negative group, there were 23 males and 2 females, aged 53.88±8.10 years. During the 5-year observation period, there was no significant difference of small shadow shape, pneumoconiosis stage, and the pneumoconiosis promotion in 5 years between the autoantibody positive group and the autoantibody negative group (P>0.05). However, the increment of small shadow area in the autoantibody positive group was higher than that in the autoantibody negative group (P<0.05). FEV(1) and MEF(50) of the autoantibody positive group were significantly lower than those of the autoantibody negative group in the fourth and third years, respectively (P<0.05). Positive autoantibody was negatively correlated with FEV(1) and MEF(50) (P<0.05). Conclusion: The positive autoantibody can't promote the progress of X-ray, but show more small shadows on chest CT; the positive autoantibody may aggravate the decline of lung function.

Abstract
Objective: To quantitatively evaluate the relationship between sleep duration and metabolic syndrome in adults in order to set up programs on prevention and treatment of metabolic syndrome in this population. Methods: Relevant studies were identified by systematically searching databases before October 2019. All statistical analyses were under the use of Stata 11.0. Results: A total of 656 319 participants including 150 638 cases with metabolic syndrome were involved in thes 38 articles. A U-shaped relationship between sleep duration and metabolic syndrome was noticed. For short and long sleep duration, the OR=1.11 (95%CI: 1.07-1.16) and 1.10 (95%CI: 1.03-1.18), respectively. Subgroup analyses on cross-sectional studies revealed that factors as men, aged under 60 years, being Asians or Caucasians would increase the risk of metabolic syndrome by 6%, 14%, 9%, and 24%, respectively for those with short sleep duration. Factors as aged 60 years and above, being black and with long sleep duration, would increase the risks of metabolic syndrome by 13% and 19%, respectively in women. In subgroup analyses on cohort studies, positive correlation between short sleep duration and metabolic syndrome was observed in both Asian (RR=1.10, 95%CI: 1.07-1.13) and in Caucasians (RR=1.56, 95%CI: 1.08-2.26) populations. Conclusions: Results of this study revealed an association between metabolic syndrome and the duration of sleep. We understand that sleep is a behavior that can be changed step by step, through adequate intervention programs, to reduce the risk of metabolic syndrome which has become an important public health issue.

Abstract
Objective: To explore differentially expressed genes (DEG) and pathways between human papilloma virus (HPV) positive and negative head and neck squamous cell carcinoma (HNSCC) and to search gene targets for diagnosis and treatment of HPV-related HNSCC. Methods: HPV-related HNSCC expression profile chips of GSE3292 (including 8 HPV-positive and 28 HPV-negative HNSCC tissues, of which 15 collected from oral cavity cancer, 9 from oropharyngeal cancer, 9 from laryngeal cancer and 3 from hypopharyngeal cancer) were selected from Gene Expression Omnibus (GEO) database of National Center for Biotechnology Information and DEG were screened out using Gene-Cloud of Biotechnology Informs (GCBI). Gene ontology and pathway enrichment analysis were performed using DAVID and protein-to-protein interaction (PPI) network was constructed by STRING. Hub genes were identified by Cytoscape and then performed pathway enrichment analysis. Finally, expression differences of hub genes in the cancer genome atlas (TCGA) database were checked using UALCAN. Results: Five hundred and seventy-three DEG were screened out from more than 25 000 genes detected in the chips including 539 up-regulated genes and 34 down regulated ones. Twenty-seven hub genes including cyclin-dependent kinases 1(CDK1), proliferating cell nuclear antigen (PCNA), minichromosome maintenance proteins (MCM) family (MCM2, MCM3, MCM6 and MCM7), replication factor C subunit 4 (RFC4) and kinesin family member 11 (KIF11) were identified after two rounds of Cytoscape screening. Gene ontology and pathway analysis showed that DEG were mainly distributed in chromosome, nucleoplasm, nuclear lumen and membrane-enclosed lumen and participated in biological processes such as DNA replication, DNA metabolism, cell cycle and cell division, and also 6 major signaling pathways centered on p53 signaling pathway (P<0.01). All hub genes were expressed differently between HPV-positive and negative HNSCC in TCGA database(P<0.01). Conclusions: Hub genes including CDK1, PCNA, MCM family (MCM2, MCM3, MCM6 and MCM7) act as an important part on HPV-induced HNSCC and the p53 pathway is the key of this process and plays different regulatory roles between two subtypes of HNSCC. CDK1, MCM7 and RFC4 are expected to be potential treatment targets for HPV-positive HNSCC while MCM2, MCM3, PCNA and KIF11 may be employed as biomarkers for diagnosis and prognosis.

Abstract
Objective: To analyze family-based haplotype frequencies of HLA-A, -B, -C, -DRB1 and -DQB1 genes and their clinical significance. Methods: The data of HLA genotyping in 3568 families undergoing related haploidentical transplantation between 2012 and 2017 at the First Affiliated Hospital of Soochow University were retrospectively evaluated. The HLA genotyping was performed by PCR amplification with sequence-based typing (PCR-SBT) and sequence-specific oligonucleotide probe (PCR-SSOP) methods. The family genetic analysis and haplotype frequencies were also investigated. Results: All the families were divided into 3 groups, including group1 of 1 422 entire families; group2 of 1 310 patients and either of their parents or one of their children; group3 of 836 patients and their HLA≥5/10 matched sibling donors. In the haplotypes with frequencies greater than 0.1% in group1+ group2, the frequency of A*11∶01-B*40∶01-C*03∶04-DRB1*11∶01-DQB1*03∶01, A*02∶07-B*51∶01-C*14∶02-DRB1*09:01-DQB1*03∶03 were significantly different between group1 and group2 (P=0.029, 0.033) . The frequency of A*11∶01-B*46∶01-C*01∶02∶01G-DRB1*09∶01-DQB1*03∶03 was significantly different between group1 and group3 (P=0.035) . The frequency of A*02∶01-B*40∶01-C*07∶02-DRB1*09∶01-DQB1*03∶03 was significantly different between group1 and group2 (P=0.034) , or group1 and group3 (P=0.034) . The frequency of A*24∶02-B*13∶01-C*03∶04-DRB1*12∶02-DQB1*03:01 was significantly different between group2 and group3 (P=0.046) . Conclusion: In this study, we summarize the prevalence of haplotype frequencies in terms of HLA-A, -B, -C, -DRB1 and-DQB1. Based on the database of family haplotype analysis, patients and donor candidates are sorted with matched HLA genotype while unmatched HLA haplotype. Even in patients without entire family information, HLA haplotype analysis assists in choosing the optimal related or unrelated donors.

Abstract
While condensed matter systems host both fermionic and bosonic quasiparticles, reliably predicting and empirically verifying topological states is only mature for Fermionic electronic structures, leaving topological Bosonic excitations sporadically explored. This is unfortunate, as Bosonic systems such as phonons offer the opportunity to assess spinless band structures where nodal lines can be realized without invoking special additional symetries to protect against spin-orbit coupling. Here we combine first-principles calculations and meV-resolution inelastic x-ray scattering to demonstrate the first realization of parity-time reversal symmetry protected helical nodal lines in the phonon spectrum of MoB_{2}. This structure is unique to phononic systems as the spin-orbit coupling present in electronic systems tends to lift the degeneracy away from high-symmetry locations. Our study establishes a protocol to accurately identify topological Bosonic excitations, opening a new route to explore exotic topological states in crystalline materials.

Abstract
Objective: To analyze 8 cases of paraquat lung transplantation in the world, and to explore the timing of lung transplantation and the factors affecting prognosis. Methods: An analysis of the clinical data of a paraquat poisoning lung transplant patient completed by The 12th People's Hospital of Guangzhou Medical University and The First People's Hospital affiliated to Guangzhou Medical University in August 2017 and literature review. Results: A 26 years old female patient was admitted to the hospital ingested 20% paraquat solution 20ml. On the 58th day of poisoning, she underwent double lung transplantation under general anesthesia. The operation was successful. Excised lungs show extensive lung fibrosis in both lungs, which was consistent with paraquat poisoning. Used tacrolimus and corticosteroids and mycophenolate antirejection, the patient discharged 46 days after surgery. 7 articles were retrieved through the search tool, and a total of 8 articles included this case were reported. Five patients who underwent lung transplantation within 1 month after poisoning all died, And 3 patients conducted lung transplantation for more than 1 month after poisoning survived; Pathogenic bacteria were isolated from the sputum in 3 of the 8 cases, all containing Pseudomonas, 2 of which died, and our case survived. Conclusion: Appropriate transplantation time window is very important for the prognosis of paraquat poisoning after lung transplantation. Active treatment of the sputum pathogens, improving the donor receptor matching, and exhausting the various means to remove the paraquat from the storage pool which may improve success rate of lung transplantation.

Abstract
Topological semimetals are characterized by symmetry-protected band crossings, which can be preserved in different dimensions in momentum space, forming zero-dimensional nodal points, one-dimensional nodal lines, or even two-dimensional nodal surfaces. Materials harboring nodal points and nodal lines have been experimentally verified, whereas experimental evidence of nodal surfaces is still lacking. Here, using angle-resolved photoemission spectroscopy (ARPES), we reveal the coexistence of Dirac nodal surfaces and nodal lines in the bulk electronic structures of ZrSiS. As compared with previous ARPES studies on ZrSiS, we obtained pure bulk states, which enable us to extract unambiguously intrinsic information of the bulk nodal surfaces and nodal lines. Our results show that the nodal lines are the only feature near the Fermi level and constitute the whole Fermi surfaces. We not only prove that the low-energy quasiparticles in ZrSiS are contributed entirely by Dirac fermions but also experimentally realize the nodal surface in topological semimetals.

Abstract
Objective: To investigate the tear film stability after trabeculectomy and its relationship with bleb morphology using Optical Quality Analysis System Ⅱ (OQAS Ⅱ). Methods: A cross-sectional study. Glaucoma patients undergoing trabeculectomy in the Eye Hospital of Wenzhou Medical University from November 2011 to November 2016 were invited by telephone to perform optical quality, bleb photography, and break-up time examinations, and history of surgeries and medications was collected. Bleb morphology was graded according to the Indiana bleb appearance grading scale. The tear film stability was the average objective scatter index value measured using OQAS Ⅱ for 10 seconds after blinking minus the baseline objective scatter index. The higher the tear film stability value, the worse the stability. The difference in the tear film stability between the surgical eyes and non-surgical eyes was compared by the Mann-Whitney U test, and the relationships between the optical quality, bleb height, extent and vascularity were compared by the Kruskal-Wallis H test. Results: Sixty-three patients (76 eyes) were enrolled in the study, including 55 surgical eyes and 21 non-surgical eyes. The mean follow-up time was (39.6±26.2) months.In the surgical and non-surgical eyes, the M(Q(R)) of tear film stability was 0.46 (0.86) and 0.23 (0.41), respectively. The tear film stability in the surgical eyes was reduced compared to the non-surgical eyes (P=0.044). The trabeculectomy group was divided into three subgroups according to the height of the filtering bleb: H0 (17 eyes), H1 (24 eyes) and H2-3 (14 eyes). The M(Q(R)) of tear film stability in the three subgroups was 0.40(0.68), 0.70(1.02) and 0.40(1.24), respectively, with no statistically significant difference detected (P=0.481). According to the bleb extent, the surgical group was divided into two subgroups: E0-1 (36 eyes) and E2-3 (19 eyes). The M(Q(R)) of optical quality in the two subgroups was 0.63 (0.78) and 0.26(1.17), respectively, with no significant difference detected (P=0.261). According to the degree of bleb vascularity, the surgical group was divided into three subgroups: V0 (25 eyes), V1 (14 eyes), and V2-3 (16 eyes). The M(Q(R)) of optical quality in the three subgroups was 0.39 (0.69), 0.55 (1.18) and 0.63 (1.24), respectively, with no significant difference (P=0.401). Conclusion: Although tear film stability decrease after trabeculectomy, the decrease is not associated with the bleb morphology. (Chin J Ophthalmol, 2019, 55:214-219).

Abstract
Objective: To analyze the characteristics and treatment of diabetic patients with superficial partial-thickness burn on feet. Methods: Eighty-three patients with superficial partial-thickness burn on 119 feet were hospitalized in our unit from January 2011 to December 2017. The medical records of the patients with 46 men and 37 women, aged 60±11 were retrospectively analyzed. The patients were divided into diabetes group and non-diabetes group according to whether they had diabetes or not, with 41 patients (60 burn feet) in diabetes group and 42 patients (59 burn feet) in non-diabetes group. Patients in diabetes group and non-diabetes group were given systemic treatment and wound dressing change. Thirty-seven diabetic patients whose wounds deepened to deep partial-thickness were divided into eschar shaving group and non-eschar shaving group according to patients' willingness and the treatment, with 14 patients in eschar shaving group and 23 patients in non-eschar shaving group. Patients in eschar shaving group were given eschar shaving operation at early stage, and patients in non-eschar shaving group were given wound dressing change. The length of hospital stay, hospitalization treatment expenses, pulse of arteria dorsal pedis and posterior tibial artery immediately after admission, deepening of wounds on feet during hospital stay, and rates of wound healing on feet of patients in diabetes group and non-diabetes group were observed and calculated. Pulses of arteria dorsal pedis and posterior tibial artery immediately after admission, deepening of wounds on feet during hospital stay, positive rates of bacteria and fungus in wounds on feet, and rates of wound healing on feet of patients in eschar shaving group and non-eschar shaving group were observed and calculated. Data were processed with chi-square test, t test, Fisher's exact propability method, and Mann-Whitney U test. Results: The length of hospital stay of patients in diabetes group was (29±20) d, which was significantly longer than that of patients in non-diabetes group [(19±13) d, t=2.730, P<0.01]. The hospitalization treatment expense of patients in diabetes group was (46 988±41 322) yuan, which was significantly more than that of patients in non-diabetes group [(29 106±24 813) yuan, t=2.396, P<0.05]. The pulses of arteria dorsal pedis and posterior tibial artery of patients in diabetes group were significantly weaker than those of patients in non-diabetes group (Z=3.278, 2.194, P<0.05 or P<0.01). The percentages of wounds on feet of patients in diabetes group deepening to deep partial-thickness burn, full-thickness skin defect with bone and tendon exposure were respectively 88.3% (53/60) and 23.3% (14/60), which were significantly higher than those of patients in non-diabetes group [47.5% (28/59) and 1.7% (1/59), χ(2)=22.867, 12.644, P<0.01]. Rate of wound healing on feet of patients in diabetes group was 78.3% (47/60), which was significantly lower than 100.0% (59/59) of patients in non-diabetes group ( χ(2)=14.351, P<0.01). There were respectively 21 and 32 feet in patients of eschar shaving group and non-eschar shaving group. There were no significantly statistical differences in pulses of arteria dorsal pedis and posterior tibial artery of patients between eschar shaving group and non-eschar shaving group (Z=0, 0.453, P>0.05). The percentage of wounds on feet of patients in non-eschar shaving group deepening to full-thickness skin defect with bone and tendon exposure was 43.8% (14/32), which was significantly higher than 0 of patients in eschar shaving group ( χ(2)=12.486, P<0.01). Positive rates of bacteria and fungus in wounds on feet of patients in eschar shaving group was significantly lower than that of patients in non-eschar shaving group (χ(2)=4.386, P<0.05 ). Rate of wound healing on feet of patients in non-eschar shaving group was 59.4% (19/32), which was significantly lower than that of patients in eschar shaving group [100.0% (21/21), P<0.01]. Conclusions: Diabetes patients with superficial partial-thickness burn wounds on feet has long length of hospital stay, high hospitalization treatment expenses. Wounds of the patients are easy to deepen, with low wound healing rate. Eschar shaving at early stage when the wounds deepened to deep partial-thickness burn is a good way to increase wound healing rate and prevent further deepening of wounds.

Abstract
Objective: To compare the ability and visibility of cone-beam CT and MSCT in showing vestibular aqueduct. Methods: An experimental anatomical study which from June 2017 to August 2017 was performed on 76 temporal bones from 38 human cadavers with unknown clinical history. They all underwent CBCT and MSCT and all images were unified and standardized. The standard position was oblique sagital reconstruction.The length of the vestibular aqueduct, the midpoint and the external aperture width were measured on the standard position. The internal aperture, isthmus and proximal portion of the vestibular aqueduct on the images of the two kinds of equipment were evaluated. The measurement results of the two devices and image quality of the vestibular aqueduct were compared. Results: There was no significant statistical difference between the results of the measurement of CBCT and MSCT(P>0.05). In CBCT images, the total display rate of internal aperture was 77.6%(59/76), and the clearly display rate was 81.4%(48/59). The total display rate of the proximal portion of vestibular aqueduct was 57.0%(45/79), and the clearly display rate was 60.0%(27/45). The total display rate of isthmus of vestibular aqueduct was 59.2%(45/76), and the clearly display rate was 60.0%(27/45). In MSCT images, the total display rate of was 46.1%(35/76), and the clearly display rate was 60.0%(21/35). The total display rate of 5 of the proximal portion of vestibular aqueduct was 56.6%(43/76), the clearly display rate was 46.5%(20/43). The total display rate of isthmus of vestibular aqueduct was 68.4%(52/76), and the clear display rate 36.5%(19/52). There was significant statistical difference between the CBCT and the MSCT (P<0.05) in displaying of internal aperture of vestibular aqueduct. Conclusion: Compared with MSCT, the image of vestibular aqueduct obtained by CBCT can meet the diagnostic requirements and CBCT have better visibility in showing some subtle structures of vestibular aqueduct than MSCT.

Abstract
Condensed matter systems have now become a fertile ground to discover emerging topological quasiparticles with symmetry protected modes. While many studies have focused on fermionic excitations, the same conceptual framework can also be applied to bosons yielding new types of topological states. Motivated by Zhang et al.'s recent theoretical prediction of double Weyl phonons in transition metal monosilicides [Phys. Rev. Lett. 120, 016401 (2018)PRLTAO0031-900710.1103/PhysRevLett.120.016401], we directly measure the phonon dispersion in parity-breaking FeSi using inelastic x-ray scattering. By comparing the experimental data with theoretical calculations, we make the first observation of double Weyl points in FeSi, which will be an ideal material to explore emerging bosonic excitations and its topologically nontrivial properties.

Abstract
A completely randomized 3 × 3 + 1 factorial experiment was conducted to evaluate the effects of sources and concentrations of Zn on growth performance, nutrient digestibility, serum biochemical endpoints, and fur quality in growing-furring female black mink. One hundred fifty healthy 15-wk-old female mink were randomly allocated to 10 dietary treatments ( = 15/group) for a 60-d trial. Animals in the control group were fed a basal diet, which consisted of mainly corn, soybean oil, meat and bone meal, and fish meal, with no Zn supplementation. Mink in the other 9 treatments were fed the basal diet supplemented with Zn from either zinc sulfate (ZnSO), zinc glycinate (ZnGly), or Zn pectin oligosaccharides (ZnPOS) at concentrations of either 100, 300, or 900 mg Zn/kg DM. The results showed that mink in the ZnPOS groups had higher ADG than those in the ZnSO groups (main effect, < 0.05). The addition of Zn reduced the G:F ( < 0.05). In addition, CP and crude fat digestibility were linearly increased with Zn supplementation ( < 0.05) and N retention tended to increase with Zn addition ( = 0.08). Dietary Zn supplementation increased the concentration of serum albumin and activity of alkaline phosphatase ( < 0.05). There was a linear effect of dietary Zn on the concentration of tibia Zn and pancreatic Zn ( < 0.05). For fur quality characteristics, the fur density and hair color of mink were improved by dietary Zn concentration ( < 0.05). Compared with ZnSO (100%), relative bioavailability values of ZnGly were 115 and 118%, based on tibia and pancreatic Zn, respectively, and relative bioavailability values of ZnPOS were 152 and 142%, respectively. In conclusion, this study demonstrates that Zn supplementation can promote growth and increase nutrient digestibility and fur quality and that ZnPOS is more bioavailable than ZnSO and ZnGly in growing-furring female mink.

Abstract
In traditional society, medical charity had strong moral and educational purposes. But this pursuit of morality faded away in modern times. As to the charity purpose, unlike the medical charity organizations that were eager to rebuild the morality and public ethics, instead, more and more interests were paid to utilitarian consideration and secular benefits. As to the social function of charity, "diseases" were no longer regarded as the extension of "poverty" , but the most direct index of rehabilitation. Medical activities became increasingly simple and developed towards professionalization, leading to the advent, to certain extent, of modern medical system. Medical charity, as a strategic approach for saving the nation and social reform, went beyond moral education, embodying national responsibility and political intention.

Abstract
Objective: To analyze the risk factors for metastasis of lymph nodes between sternocleidomastoid and sternohyoid muscle (LNSS) in papillary thyroid cancer (PTC). Methods: Papillary thyroid cancer patients with clinically positive lateral lymph node metastasis (cN1) who underwent surgery including LNSS dissection between May 1, 2013 and May 31, 2016 at the Department of Head and Neck Surgery, Fudan University Shanghai Cancer Center were retrospectively studied. Logistic regression analysis was performed to evaluate possible clinicopathological factors related to LNSS metastasis. Results: In 85 patients, 54 patients (63.5%) showed LNSS in their surgical specimen, and 20 patients (23.5%) had pathologically positive LNSS metastasis. Patients with LNSS showed preoperatively higher levels of serum thyroid stimulating hormone (TSH) and thyroid peroxidase antibody (TPO-Ab) compared to patients only with fibrofatty tissues between sternocleidomastoid and sternohyoid muscle (P<0.05), and they also displayed a higher proportion of multifocality in ipsilateral thyroid lobe (P<0.05). Multi-factor analysis indicated that LNSS metastasis was correlated with original tumor size (OR=1.819, 95%CI 1.050-3.850, P=0.002) and Level Ⅳ lymph node metastasis (OR=2.190, 95%CI 1.132-2.334, P=0.005). Furthermore, the number of positive LNSS was tightly correlated to that of level Ⅳ lymph node metastasis(P<0.05). Conclusion: LNSS metastasis is occult but not quite rare in PTC. Patients with extensive lymph node metastasis in Level Ⅳhave a higher risk for metastasis of LNSS.

Abstract
Insulin-like peptides (ILPs) act through a conserved insulin signaling pathway and play crucial roles in insect metabolism, growth, reproduction, and aging. Application of bovine insulin is able to increase vitellogenin (Vg) mRNA and protein levels in female insects. Here, we first show that injection of bovine insulin into previtellogenic Chrysopa septempunctata female adults promoted ovarian growth, increased Vg protein abundance, elevated reproductive performance, and enhanced protease activity. These data suggested that ILPs play crucial roles in reproductive regulation of the green lacewing, C. septempunctata.

Abstract
Objective: To investigate the clinical and laboratorial characteristics of patients with myelodysplastic syndrome (MDS) and erythroid hyperplasia. Methods: MDS patients whose bone marrow was hypercellular with erythroid lineage more than 50% and blasts account for less than 20% of non-erythroid cells were enrolled in this study. The ratio of mature erythrocytes to nucleated erythrocytes was no more than 20, namely MDS patients with erythroid hyperplasia(MDS-E). The retrospective analysis comprised 102 patients with MDS-E from the First Affiliated Hospital of Suzhou University. Clinical characteristics, karyotype, and the prognostic significance of erythroid hyperplasia were evaluated. Results: A total of 48 MDS-E patients (47.1%) presented a variety of cytogenetic abnormalities. The most frequently involved chromosomes were chromosome 8 (39.5% of all abnormal karyotypes), chromosome 7 (22.9%), followed by chromosome 5 (18.8%), chromosome 1 (16.7%) and chromosome 20 (16.7%). Hemoglobin (Hb) level affected the prognosis by survival analysis. The overall survival (OS) of MDS-E patients with Hb equal or more than 70 g/L was longer than that of patients less than 70 g/L (P<0.001). Allogeneic hematopoietic stem cell transplantation (HSCT) significantly improved the OS compared with best supportive care (P<0.001) and chemotherapy (P<0.001). The extent of erythroid hyperplasia in bone marrow did not impact on prognosis (P=0.187). Conclusions: Compared with previous reports of MDS patients, MDS-E patients have higher level of erythroid hyperplasia, more common erythroid dyshematopoiesis, more frequent 8 and 1 chromosome abnormalities. The degree of erythroid hyperplasia is not correlated with prognosis. Allogeneic hematopoietic stem cell transplantation improves the prognosis.

Abstract
A 3 × 3 + 1 factorial experiment was conducted based on a completely randomized design to evaluate the effects of different sources of copper on plasma metabolites, nutrient digestibility, relative copper bioavailability, and retention of some minerals in male mink. Animals in the control group were fed a basal diet, which mainly consisted of corn, fish meal, meat and bone meal, and soybean oil, with no copper supplementation. Mink in the other 9 treatments were fed the basal diet supplemented with Cu from reagent-grade copper sulfate (CuSO4), tribasic copper chloride (TBCC), or copper methionine (CuMet). Copper concentrations of the experimental diets were 50, 100, and 150 mg Cu/kg DM. Blood samples were collected via the toe clip at the end of study (d 42) to determine blood hematology and blood metabolites. A metabolism trial of 4 d was conducted during the last week of experimental feeding. There was a linear (P < 0.01) effect of dose of Cu on plasma Cu concentrations, ceruloplasmin concentration, and Cu-Zn superoxide dismutase activity. A linear response to Cu dose was noted for fat (P < 0.05) digestibility. Supplemental dose of Cu linearly increased (P < 0.05) liver Cu and decreased (P < 0.05) liver Zn level but did not alter liver Fe. The concentration of liver Cu of the mink fed with TBCC and CuMet diets was greater (P < 0.05) than that fed CuSO4. Compared with CuSO4 (100%), relative bioavailability values of TBCC were 104 and 104%, based on serum ceruloplasmin and liver copper, respectively, and relative bioavailability values of CuMet were 130 and 111%. CuMet and TBCC are more bioavailable than CuSO4. In conclusion, the relative bioavailability of CuMet obtained in this study was greater than that of CuSO4 and TBCC. Dose of Cu had an important effect on the regulating ceruloplasmin concentration, Cu-Zn superoxide dismutase activity, and the digestion of dietary fat in mink.

Abstract
OBJECTIVE Indications for resection of hepatocellular carcinoma (HCC) remain controversial. This study aimed to identify prognostic factors that affect overall survival (OS) and disease-free survival (DFS) in patients with HCC after hepatectomy. METHODS From 2004 to 2010, 601 patients with HCC who underwent resection were enrolled. Factors stratified into the host, biochemical, surgical treatment and tumor-related features in terms of recurrence and overall survival were analyzed. Prognostic factors were evaluated by univariate and multivariate analyses, with Kaplan-Meier survival analyses and Cox proportional hazard model. RESULTS The overall survival rates of 1-, 3- and 5- year were 79, 62, and 54 %, and the corresponding DFS rates were 51, 38 and 31 %, respectively. In a multivariate analysis, Child-Pugh, serum AFP level, ALT level, time for hepatic resection, tumor differentiation, maximum size of tumors, local necrosis, portal vein tumor thrombus, and TNM Stage were correlated significantly with patients' OS. Gender (P = 0.046), cigarette smoking (P = 0.007), serum AFP level (P = 0.001), GGT level (P = 0.002), maximum size of tumors (P = 0.009), liver cirrhosis (P = 0.025), portal vein tumor thrombus (P = 0.022), microvascular tumor thrombus (P = 0.007) and TNM Stage (P = 0.001) were significantly affected DFS. CONCLUSION Preoperative AFP level, maximum size of tumors, portal vein tumor thrombus and TNM Stage were revealed as important prognostic factors for OS and DFS through follow-up of a relatively large cohort of Chinese HCC patients.

Abstract
The objectives of the trial were to investigate the effects of supplementing rare earth element (REE) cerium (Ce) on rumen fermentation, nutrient digestibility, methane (CH4 ) production, nitrogen (N) balance and plasma biochemical parameters in beef cattle. Four Simmental male cattle, aged at 14 months, with initial liveweight of 355 ± 8 kg and fitted with permanent rumen cannulas, were used as experimental animals. The cattle were fed with a total mixed ration (TMR) composed of concentrate mixture and corn silage. Four levels of cerium chloride (CeCl3 ·7H2 O, purity 99.9%), that is 0, 80, 160 and 240 mg CeCl3 /kg DM, were added to basal ration in a 4 × 4 Latin square design. Each experimental period lasted 15 days, of which the first 12 days were for pre-treatment and the last 3 days were for sampling. The results showed that supplementing CeCl3 at 160 or 240 mg/kg DM increased neutral detergent fibre (NDF) digestibility (p < 0.05) and tended to increased acid detergent fibre (ADF) digestibility (p = 0.083). Supplementing CeCl3 at 80, 160 or 240 mg/kg DM decreased the molar ratio of rumen acetate to propionate linearly (p < 0.05). Supplementing CeCl3 at 160 or 240 mg/kg DM decreased total N excretion, urinary N excretion and increased N retention (p < 0.05), increased excretion of total urinary purine derivatives (PD) (p < 0.05) and decreased CH4 /kg DMI (p < 0.05). In conclusion, supplementing CeCl3 at 160 or 240 mg/kg DM in the ration of beef cattle increased the digestibility of NDF, decreased the molar ratio of rumen acetate to propionate, increased N retention and microbial N flow and decreased CH4 /kg DMI.

Abstract
OBJECTIVE To study the appropriate surgical procedure for Stage I endometrial carcinoma (EC), the clinical and pathological features and prognosis factors, as well as types were analyzed retrospectively. MATERIALS AND METHODS This is a retrospective study of 277 patients with early-stage EC in clinical Stages I that received surgery between January 2000 and March 2008. The appropriate surgical procedures were divided into three types (procedure I-III: hysterectomy with or without ovary preservation, subradical hysterectomy plus pelvic lymph node biopsy, and radical hysterectomy pelvic plus lymphadenectomy) according to the clinical stage. RESULTS Tumor invasion of the cervix and deep muscularis as well as the parametrium, EC Stage Ib, grade 3 and ascites had carcinoma cells, were high-risk factors of EC metastasis to the retroperitoneum (p < 0.05). The ovarian preservation of EC Stage Ia had no effect on overall survival. The three types of procedure for the EC Stage Ia were not correlated significantly to the three-year and five-year survival rates. The three-year and five-year survival rates of three surgical procedures for the EC Stage Ib were significantly correlated. The survival rates of surgical procedures II and III were significantly higher than that of procedure I (P < 0.05). CONCLUSION Subradical hysterectomy plus pelvic lymph node biopsy was recommended for EC Stage 1b with high-risk factors. There was no evidence of benefit in terms of overall or recurrence-free survival for radical hysterectomy plus pelvic lymphadenectomy in women with Stage I EC.

Abstract
The objectives of the trial were to study the effects of rare earth element (REE) lanthanum (La) on the in vitro rumen methane (CH4 ) and volatile fatty acid (VFA) production and the microbial flora of feeds. Four feed mixtures with different levels of neutral detergent fibre (NDF), that is 20.0% (I), 31.0% (II), 41.9% (III) and 52.7% (IV), were formulated as substrates. Five levels of LaCl3 , that is 0, 0.4, 0.6, 0.8 and 1.0 mmol/kg dry matter (DM), were added to the feed mixtures, respectively, as experimental treatments in a two-factor 5 × 4 randomized design. The in vitro incubation lasted for 24 h. The results showed that supplementing LaCl3 increased the total gas (p < 0.001) production and tended to increase the total VFA production (p = 0.072) and decreased the CH4 production (p = 0.001) and the ratios of acetate/propionate (p = 0.019) and CH4 /total VFA (p < 0.001). Interactions between LaCl3 and NDF were significant in total gas production (p = 0.030) and tended to be significant in CH4 production (p = 0.071). Supplementing LaCl3 at the level of 0.8 mmol/g DM decreased the relative abundance of methanogens and protozoa in the total bacterial 16S rDNA analysed using the real-time PCR (p < 0.0001), increased F. succinogenes (p = 0.0003) and decreased R. flavefaciens (p < 0.0001) whereas did not affect R. albus and anaerobic fungi (p > 0.05). It was concluded that LaCl3 decreased the CH4 production without negatively affecting feed digestion through manipulating rumen microbial flora when feed mixtures with different levels of NDF were used as substrates.

Abstract
The study was conducted to investigate the effect of dietary manganese (Mn) on reproductive performance of female Ussuri raccoon dogs (Nyctereutes procyonoides) during the breeding season. Healthy female Ussuri raccoon dogs (n=72) were randomly divided into six groups of twelve each. The six experimental diets were formulated to contain graded amounts of Mn (0, 40, 80, 120, 200 and 400mg/kg of diet; Groups A through F, respectively). Litter size of Group D was greater than that of Groups A, B, C and E (P<0.05), with Group E having the smallest litter size. Values of number born alive were affected by different amounts of organic Mn. Number of pups born alive in Group D was greater than that of Groups B, C, E and F (P<0.05). Number of pups weaned alive for Group D was greater than that of Groups A, B, C and E (P<0.05). Mn supplementation of the control diet (containing 24.32 mg/kg from raw materials) with 120 mg/kg of Mn was adequate for female Ussuri raccoon dogs during the breeding season, based on positive effects of reproduction performance.

Abstract
Two experiments were conducted to study the effects of dietary manganese levels on growth performance, nutrients digestibility, and N balance of minks during growing period. In experiment 1, 75 healthy male minks (60 days old) were selected and randomly divided into five groups with different types of diet. The diet was supplemented with 0 (control), 50, 100, 300, and 600 ppm of manganese as MnSO4 of dry matter (DM) in basic diet, respectively. From early July to middle September, the results showed that the final body weights of minks were significantly affected by diets (P < 0.05). Average daily gains (ADG) were significantly higher in the 300-ppm manganese group than those in other groups. The ratio of feed to body weight gain (F/G) was significantly affected by manganese level (P < 0.05). In experiment 2, 45 male minks (75 days old) with the same body weight were selected from each group of experiment 1 to carry out the nutrient digestion and N-balance tests which lasted for 4 days for the collection of the feces and urine, and the diets and treatment codes were same as in experiment 1. The results showed that no significant differences were found in DM, crude protein (CP), and crude carbohydrate (CC) digestibility among all groups (P > 0.05), but ether extract (EE) and gross energy (GE) digestibility were all the highest in the 300-ppm group. N intake and fecal N were similar among all groups (P > 0.05). Urinary N was lower in the 300-ppm group; in contrast, N retention was higher in this group (P < 0.05). In conclusion of experiment 1 and experiment 2, the diet supplemented with 300 ppm of manganese (as manganese sulfate) could improve the growth performance and increase the EE and GE digestibility of mink during the growing period and moreover reduce the nitrogen emissions to the environment, and the optimal total manganese level in mink's diet was 409.16 in DM during the growing period.
