Abstract
As the backbone force of China's social and economic construction, the health status of workers is closely related to the nation's productivity and social development. Currently, cancers have become one of the major diseases threatening the health of workers. However, there are still many shortcomings in the cancer screening services for the workers. To standardize cancer screening services for workers, ensure the quality of screening services, and improve the overall screening effectiveness, 19 institutions, including Peking Union Medical College Hospital of the Chinese Academy of Medical Sciences, have jointly formulated the Group Standard "Specification for service of cancer screening for workers (T/CHAA 023-2023)". This standard follows the principles of "legality, scientific rigor, advancement, and feasibility" and combines the frontier scientific advances in cancer screening. It clarifies the relevant requirements for service principles, service design, service delivery, service management, service evaluation, and improving worker cancer screening. Implementing this group standard will help connect the common screening needs of workers, employers, and cancer screening service providers, standardize the screening process, improve screening quality, and ultimately increase the early diagnosis rate and survival rate of cancer patients. Consequently, this group standard will help safeguard workers' health rights and interests, ensure the labor force resources, promote the comprehensive coordinated and sustainable development of society, and contribute to realizing the "Healthy China 2030" strategic policy.

Abstract
C-oligosaccharides are found in natural products and drug molecules. Despite the considerable progress made during the last decades, modular and stereoselective synthesis of C-oligosaccharides continues to be challenging and underdeveloped compared to the synthesis technology of O-oligosaccharides. Herein, we design a distinct strategy for the stereoselective and efficient synthesis of C-oligosaccharides via palladium-catalyzed nondirected C1-H glycosylation/C2-alkenylation, cyanation, and alkynylation of 2-iodoglycals with glycosyl chloride donors while realizing the difunctionalization of 2-iodoglycals. The catalysis approach tolerates various functional groups, including derivatives of marketed drugs and natural products. Notably, the obtained C-oligosaccharides can be further transformed into various C-glycosides while fully conserving the stereochemistry. The results of density functional theory (DFT) calculations support oxidative addition mechanism of alkenyl-norbornyl-palladacycle (ANP) intermediate with α-mannofuranose chloride and the high stereoselectivity of glycosylation is due to steric hindrance.

Abstract
PURPOSE/OBJECTIVE(S) Patients receiving brain Intensity-modulated Proton Therapy (IMPT) are treated with 1-3 fields. Typically, beam angles must be selected manually, requiring substantial planner time and experience. The choice of beam angles has a major impact on the treatment plan quality. An AI model was developed to automate this process aiming to improve efficiency and potentially plan quality. AI performance was tested by comparing predicted beam angles to the human ground truth angles and evaluating plans resulting from each set of beam angles. MATERIALS/METHODS Previously treated IMPT brain patients were divided into a training (n = 40) and validation set (n = 10) for the AI. Beam-angle selection in the AI was cast as a multi-label classification problem, training the convolution neural network with a Circular Earth Mover's Distance based regularization and multi-label circular-smooth label technique. An analytical post-processing algorithm is employed to minimize distance to the target and avoid organs-at-risk. Finalized gantry angle predictions are discretized in steps of 5°. For an independent test set of n = 10 patients beam angles were predicted by the AI and compared to those chosen by human planners. Both sets of angles were used to create treatment plans with an automated knowledge-based planning (KBP) tool for brain IMPT utilizing single-field optimization and robust optimization. Plan differences are therefore solely due to the choice of beam angles as automated KBP removes human optimization variability. Resulting plan quality was compared by standard clinical dosimetric parameters to the CTV, brain, brainstem, cochlea, cord, eye, lens, optic chiasm, optic nerves, pituitary, and temporal lobes. RESULTS All Human and AI selected beam angles are shown in the table. For cases 1-6, AI and Human selected beam angles were within ±15° and resulting plans showed minimal dosimetric differences. In cases 7-9 AI beam angles reduced max dose while keeping organ-at-risk dose within ±2 Gy. In case 10 the AI chosen beam angles reduced cord Dmax by 9.1 Gy but increased left eye Dmax by 4.9 Gy, other organs-at-risk showed minimal differences. CONCLUSION Gantry beam angle selection was automated by a newly developed AI model and tested on 10 brain IMPT patients. The comparison showed that the AI often chooses similar beam angles to the human planners. When there are differences, dosimetric analysis demonstrated that plans created from AI beam angles have at least the same quality as the human ones. Results motivate further research into this approach showing the AI being a promising tool to fill a current gap in the strive for automating proton treatment planning, increasing planning efficiency and potentially quality.

Abstract
We report a redox-neutral, visible-light-mediated difluoroalkylation of unactivated C(sp3)-H bonds in amides via nitrogen-centered radicals triggered intramolecular hydrogen atom transfer. Notably, all types (tertiary, secondary, and primary) of γ-C(sp3)-H bonds displayed excellent reactivity. This methodology presents a facile route for the regioselective introduction of α,α-difluoroketone fragments into organic molecules. Moreover, the resulting gem-difluoroketones can be readily converted to structurally diverse difluoro-containing molecules, offering broad potential applications in medicinal chemistry and chemical biology.

Abstract
This study aimed to identify risk factors for involuntary referral by police to emergency room (ER) psychiatric services for community-based patients with a mental illness via a generalized estimating equation (GEE) analysis. The analysis was based on data from the Management Information System of Psychiatric Care (MISPC) system for patients with a severe mental illness in Taipei, Taiwan and registered referral records of the police. Data on 6378 patients aged ≥20 years were used in this study, including 164 patients who were involuntarily referred to the ER by the police and 6214 patients who were not during the period of January 1, 2018 to December 31, 2020. GEEs were utilized to explore possible risk factors of repeated involuntary referral to ER psychiatric services for patients with a severe mental illness. The logistic regressions indicated that patients defined as "severe" according to the Mental Health Act of Taiwan (crude odds ratio (OR): 3.840, 95 % confidence interval (CI): 2.407-6.126), with a disability (crude OR: 3.567, 95 % CI: 1.339-9.501), with two or more family members with a psychiatric disorder (crude OR: 1.598, 95 % CI: 1.002-2.548), with a history of a suicide attempt (crude OR: 25.582, 95 % CI: 17.608-37.167), and with a history of domestic violence (crude OR: 16.141, 95 % CI: 11.539-22.579) were positively associated with involuntary referral to ER psychiatric services. However, age (crude OR: 0.971, 95 % CI: 0.960-0.983) and the MISPC score (crude OR: 0.834, 95 % CI: 0.800-0.869) were inversely associated with involuntary referral to ER psychiatric services. After adjusting for demographics and potential confounders, we found that patients defined as "severe" (Exp (β): 3.236), with a disability (Exp (β): 3.715), with a history of a suicide attempt (Exp (β): 8.706), and with a history of domestic violence (Exp (β): 8.826), as well as age (Exp (β): 0.986) and the MISPC score (Exp (β): 0.902) remained significantly associated with repeated involuntary referral to ER psychiatric services. In conclusion, community-based mentally ill patients with a history of a suicide attempt, with a history of domestic violence, with a severe illness, and with a profound level of disability were highly associated with involuntary referral to ER psychiatric services. We suggest that community mental health case managers identify significant factors associated with involuntary referral to ER psychiatric services to accordingly arrange case management plans.

Abstract
Objective: To investigate the outcomes including major complications and prognosis of extremely preterm infants with gestational age ≤25+6 weeks. Methods: The cross-sectional study enrolled 233 extremely preterm infants with gestational age ≤25+6 weeks who were admitted to the Department of Neonatology of Shenzhen Maternity and Child Healthcare Hospital from January 2015 to December 2021. The clinical data including perinatal factors, treatments, complications, and prognosis were extracted and analyzed. These extremely preterm infants were also grouped according to gestational age and year of admission to further analyze their survival rate, major complications, causes of death, and long-term outcomes. The comparisons between the groups were performed with Chi-square test and Kruskal-Wallis. Results: Among these 233 extremely preterm infants, 134 (57.5%) were males and 99 (42.5%) females. The gestational age was (24.6±0.9) weeks, the birth weight was 710.0 (605.0,784.5) g, and the overall survival rate was 61.8% (144/233). Among the surviving extremely preterm infants, the earliest gestational age was 22+2 weeks and the lowest birth weight was 390 g. There were 17.6% (41/233) of extremely preterm infants had treatment withdrawn and were discharged in line with the will of guardians. Among the rest 192 extremely preterm infants managed with aggressive treatments, 14 (7.3%) died in hospital and 34 (17.7%) had treatment withdrawn later due to severe complications. Of the 192 extremely preterm infants, 144 (75.0%) survived, and the survival rate increased year by year (χ2=26.28, P<0.001) while the mortality decreased year by year (χ2=14.09, P=0.027). Among the survivors, 20.8%(30/144) had no major complications, and the incidence of complications was also negatively related with the gestational age (χ2=7.24, P=0.044), and the length of invasive ventilation was negatively related to the gestational age (χ2=29.14, P<0.001). In the group of less than 23+6 weeks, all extremely preterm infants had one or more major complications. The follow-up were completed in 122 infants and revealed that delayed motor development, language retardation, and hearing and vision impairment accounted for 17.2% (21/122), 8.2% (10/122) and 17.2% (21/122), respectively. Conclusions: Extremely preterm infants with gestational age ≤25+6 weeks are difficult to treat, but the survival rate of infants undergoing aggressive treatments increases year by year. Although the prevalence of major complications is still high, most extremely preterm infants have acceptable prognosis during follow-up.

Abstract
Objective: To evaluate the effect of ultrasound diagnosis of thyroid micro-malignant nodules and accumulate practical experience for the management of active surveillance for them, so as to avoid overtreatment. Methods: A total of 949 patients who were diagnosed with thyroid malignant nodules using ultrasonography, with the nodules being less than 1 cm in size and without regional lymph node metastasis or distant metastasis, were included. They were treated by the same surgeon of the Department of Head and Neck Surgery, Cancer Hospital, Chinese Academy of Medical Sciences from February 2014 to December 2020. 112 patients chose immediate surgery. The rest patients were asked to accept ultrasound examination every 6 months to 1 year. Follow-up endpoints: tumor size growth of 3 mm, tumor volume increase greater than 50%, lymph node metastasis or distant metastasis. Results: The median follow-up time was 19 months. 713 patients underwent surveillance for more than 6 months. Of the 713 patients, 570 (79.9%) were women, with mean age at 43.5 years old. Tumor progression was observed in 47 (6.6%) patients with a cumulative incidence of 2.7% (1 year), 7.2% (2 years) and 9.5% (3 years). In multivariate analysis, patient age [HR=0.508, 95%CI: 0.275-0.939, P=0.031], lesion number [HR=2.945, 95%CI: 1.593-5.444, P=0.001] and tumor size [HR=2.245, 95%CI: 1.202-4.192, P=0.011] at the beginning of observation were independent risk factors for tumor progression in patients with minimal thyroid malignant nodules during follow-up. During a median (range) active surveillance of 19 (6-80) months, 74 patients chose surgery during the surveillance. Among the 186 patients who underwent surgery, only 3 patients were diagnosed with fibrotic nodules in pathology, while the rest were papillary thyroid carcinoma. The ultrasound accuracy reached 98.4%(183/186). Conclusions: Ultrasonography is an effective method of diagnosing malignant thyroid nodules. Thyroid micro-malignant nodules progress slowly. As a result, it is safe to observe them instead of taking immediate surgery. Patient age, lesion number and tumor size at the beginning of observation are independent risk factors for the tumor progression of malignant nodules.

Abstract
Herein, a practical and highly efficient method for visible-light-induced copper-catalyzed N-aminoquinoline-directed asymmetric C(sp3)-C(sp3)-H glycosylation was reported. At the same time, C(sp3)-C(sp3)-H glycosylation of nondeoxysugars with amino acids to construct C-glycopeptides was achieved. This approach promoted the synthesis of various C-glycopeptides and provided a new model for the synthesis of C-glycoamino acids.

Abstract
We described a novel palladium-catalyzed C-H glycosylation of indole or tryptophan for a one-pot stereoselective synthesis of 2,3-diglycosylindoles and tryptophan-C-glycosides. In this strategy, the use of air and base-free and ligand-free conditions provided a highly efficient route to construct C-glycosides. The method can be applied to a wide range of cost-effective and convenient glycosyl chloride donors. Mechanistic studies indicated that the indole 2,3-diglycosylation sequence was C3 and then C2.

Abstract
Objective: To examine the associations between plasma n-3 polyunsaturated fatty acids (PUFAs) in the second trimester and gestational diabetes mellitus (GDM) among Chinese pregnant women. Methods: Based on data from the Tongji-Shuangliu Birth Cohort enrolled from 2017 to 2019 in the Shuangliu Maternal and Child Health Hospital, it conducted a case-control study among 269 GDM cases who were diagnosed by 75 g oral glucose tolerance test, and 538 non-GDM controls matched at a 1∶2 ratio on maternal age and gestational weeks. The age range of the 807 women was 18-40 years. Fasting plasma n-3 PUFAs were determined by gas chromatography-mass spectrometry in the second trimester (24-28 weeks). Participants were categorized into quartiles (Q1-Q4) of plasma n-3 PUFAs based on distributions in the control group. Conditional logistic regression models were applied to estimate the associations between plasma n-3 PUFAs and GDM. Results: The median (interquartile) relative concentrations of plasma n-3 PUFA C22∶5n-3 was significantly lower in women with GDM 0.87 (0.72, 1.07) compared with women without GDM 0.94 (0.75, 1.19)(P=0.001). Plasma n-3 PUFA C22∶5n-3 was inversely associated with GDM, with an OR (95%CI) of 0.75 (0.62-0.90) for each SD increase of relative concentration. Compared with the Q1 group, the OR values and 95%CIs of Q2, Q3, and Q4 groups were 0.97 (0.62-1.51), 0.72 (0.45-1.15), and 0.54 (0.32-0.90), respectively (Ptrend<0.05). However, there were no significant associations of C18∶3n-3, C20∶5n-3, C22∶6n-3, and total n-3 PUFAs with GDM. Conclusion: Plasma n-3 PUFA C22∶5n-3 was inversely associated with GDM during the second trimester.

Abstract
Abstract
Study question
How machine learning assisted in generating patient-friendly corifollitropin alfa protocol in normal responders?
Summary answer
In retrospective experiments, our machine learning model integrated physiological measurements of patients and clinical experience to generate a patient-friendly corifollitropin alfa protocol.
What is known already
Long-acting corifollitropin alfa can simplify the regimen, minimizing injections during the whole cycle. The previous study has described the patient-friendly protocol using corifollitropin alfa without routine pituitary suppression in normal responder can result in non-compromised clinical outcomes. Some studies showed machine learning can help with making clinical decisions and have the ability to learn from physiological measurements. Those methods effectuate certain points throughout short-acting menotropin protocols, however, there are still no robust AI tools for long-acting corifollitropin alfa protocols.
Study design, size, duration
1,309 cycles were collected at Stork Fertility Center from November 2016 to October 2019, and 1,221 cycles were available after data cleaning and applying exclusion criteria, which Anti-Mullerian Hormone (AMH) is lower than 2. The data from electronic medical records (EMRs) consisted of age, AMH, body weight, luteinizing hormone (LH), and estradiol (E2) concentrations measured on revisit. Evaluation is performed by one physician who has more than 20 years of experience in IVF. Participants/materials, setting, methods: The protocol generator consisted of 5 parts: doses of Elonva, trigger type, doses of recombinant follicle-stimulating hormone (rFSH), doses of recombinant luteinizing hormone (rLH), and day of oocyte retrieval. The protocol was predicted by age, AMH, and weight firstly, then fine-tuned by LH and E2 after the first revisit. We used the gradient boosting decision tree algorithm to learn the protocol. The dataset was randomly split into 80% for training and 20% for testing.
Main results and the role of chance
In classification, the model predicted the dose of Elonva achieved an accuracy of 0.913 and an AUC of 0.946, and trigger type got an accuracy of 0.901 and AUC of 0.852 only using features on stimulation day (SD) 1 and gained 0.012 and 0.056 in accuracy and AUC correspondingly after adding features on the first revisit day. In regression, the mean absolute error (MAE) of rFSH dose, rLH dose, and oocytes retrieved day was 156.30 IU, 232.75 IU, and 0.80 days respectively, and after refining, the MAE dropped to 92.37 IU, 100.07 IU, and 0.46 days. The error of predictions in rFSH and rLH was almost equal to half increments of rFSH (150 IU) and one increment rLH (75 IU). This indicated that our model could provide a better prediction of these clinical decisions with one revisit only.
Limitations, reasons for caution
The present study was a single-center retrospective, and only analyzed the data from normal responders, whose AMH was equal or greater than 2. Though, the recommendations of our system act as references, the physician will make the final decision.
Wider implications of the findings: Our result showed the potential of machine learning in generating protocols is promising. Recommendations generated by our model can provide the junior clinical teams to optimize the clinical plans and learn from the experience of experts. We look forward to applying our machine learning model to different protocols.

Abstract
We described a novel palladium-catalyzed domino procedure for the preparation of (hetero)aryl thio/selenoglycosides. Readily available (hetero)aryl iodides and easily accessible 1-thiosugars/1-selenosugars are utilized as the substrates. Meanwhile, 10 types of sugars are quite compatible with this reaction with good regio- and stereoselectivity, high efficiency, and broad applicability (up to 89%, 53 examples). This method enables the straightforward formation of the C(sp2)-S/Se bond of (hetero)aryl thio/selenoglycosides.

Abstract
Objective: To explore the applied value of super-selective cervical lymph node dissection in papillary thyroid carcinoma (PTC) patients with clinically suspicious lateral lymph node metastasis (LNM). Methods: We retrospectively analyzed the clinical data of 232 cN1b PTC patients who underwent surgery from September 2013 to May 2018 in the Department of Head and Neck Surgical Oncology, National Cancer Center. Among them, 90 cases received super-selective neck dissection (level Ⅲ and IV) and 142 cases underwent selective neck dissection (level Ⅱ-Ⅳ). The LNM of two groups were analyzed. Results: Postoperative pathological results showed that 173 cases had LNM in the central compartment. The LNM cases of level Ⅱ-Ⅳ were 47, 147 and 130, respectively. Eight patients of super-selective neck dissection and 6 of selective neck dissection had postoperative lymphatic fistulas (P=0.146). No patients in super-selective neck dissection group while 9 patients in the selective lymph node dissection group had postoperatively permanent impairment of shoulder mobility, the difference was statistically significant (P=0.015). In the super-selective neck dissection group, 2 patients had long-term postoperative incision discomfort, and 5 cases had obvious cicatrix after surgery. In the patients with selective neck dissection, 27 cases experienced long-term incision discomfort after surgery, and 26 patients had apparent scar tissue, the differences were statistically significant (P<0.005). There was no recurrence during the follow-up. Conclusions: Super-selective neck dissection is a feasible, safe and effective treatment for cN1b PTC patients. It can improve the quality of postoperative life and avoid the over treatment for patients.

Abstract
Objective: To evaluate and compare the quality of life (QOL) in patients with hypopharyngeal squamous cell carcinoma after laryngeal preservation surgery and total laryngectomy. Methods: We selected parts of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 and the Head and Neck Module (EORTC QLQ-C30 and EORTC QLQ-H&N35) and designed the QOL questionnaire. We investigated 42 patients with hypopharyngeal squamous cell carcinoma underwent laryngeal preservation surgery and 38 patients underwent total laryngectomy by QOL questionnaire and followed up their survival. Results: The somatic function dimension, psychological function dimension, and social function dimension of patients underwent laryngeal preservation surgery were (92.46±15.71), (80.56±22.67) and (90.08±19.50), respectively, which were higher than (79.39±32.75), (68.42±25.05) and (61.84±29.55) of the total laryngectomy group (P<0.05), while the economic dimension was not significantly different between the two groups (P>0.05). The social function dimension (including social support and socialization, family relationship) of laryngeal preservation surgery group were (89.04±25.47) for postoperative time < 70 months and (90.94±13.28) for postoperative time ≥70 months, which were higher than (65.48±29.14) and (57.35±30.32) of the total laryngectomy group (P<0.01). Conclusions: The somatic function dimension, psychological function and social function of patients with hypopharyngeal squamous cell carcinoma underwent laryngeal preservation surgery obtain a better QOL than patients underwent total laryngectomy. Therefore, we should improve the laryngeal function and QOL of patients under the premise of ensuring the survival rate.

Abstract
Objective: To analyze the EGFR mutation profile of lung cancer patients in Yunnan, and to provide evidence for clinical personalized treatment. Methods: Demographic and clinical data of 2 967 lung cancer patients undergoing EGFR identification were collected and analyzed from January 2014 to August 2019 in Yunnan Cancer Hospital. Results: The proportion of EGFR mutation in 2 967 patients with lung cancer was 46.2%. Univariate analysis showed that the proportion of EGFR mutation in women was higher than that in men (P<0.001) and displayed a downward trend with age (P=0.03). The mutation rate of ethnic minorities was higher than Han (P=0.012). Mutation rate in patients without smoking history was higher than those with smoking history (P<0.001), and patients without drinking history was higher than patients with drinking history (P<0.001). Mutation rate in patients without family history of lung cancer was higher than those with family history (P=0.008). The mutation rate of adenocarcinoma was higher than other pathological types (P<0.001). The mutation rate was different among stages, and it was higher in early patients than that in advanced patients (P<0.001). The mutation rate of tissue specimens was higher than those of cytology and peripheral blood samples (P<0.001). The mutation rate of Xuanwei area was lower than that in non-Xuanwei area (P<0.001). Multivariate analysis showed that gender (P<0.001), age (P=0.036), smoking history (P<0.001), pathological type (P<0.001), specimen type (P<0.001), and whether or not Xuanwei area (P<0.001) were the independent factors of EGFR mutation.The EGFR mutation was more common in female, non-smokers, adenocarcinoma, non-Xuanwei area, tissue specimen and young lung cancer patients.The mutation types of EGFR in 1 370 cases mainly included 19-Del and L858R. The predominant mutation of EGFR in Xuanwei area was L858R, while in non-Xuanwei area was 19-Del.The mutation rates of G719X, G719X+ L861Q, G719X+ S768I, and S768I in Xuanwei were higher while the mutation rates of 19-Del, L858R, and 20-ins were lower than non-Xuanwei area (P<0.05). The 19-Del mutation rate of ethnic minorities is higher than that of Han (P<0.001). The combined mutation rate of G719X, L861Q in Han was higher than that of ethnic minorities (P=0.005). Conclusions: The EGFR mutation rate in lung cancer patients in Yunnan is similar to Asian and Chinese, and higher in female, non-smokers, adenocarcinomas, young and non-Xuanwei area patients. The most common types of EGFR mutation in Yunnan are 19-Del and L858R. The predominant mutation of EGFR in Xuanwei area is L858R, while in non-Xuanwei area is 19-Del. The mutation rates of G719X, G719X+ L861Q, G719X+ S768I and S768I are higher in Xuanwei patients than those in non-Xuanwei patients. The combined mutation rate of G719X and L861Q in Han nationality is higher than that of ethnic minorities.

Abstract
Background This study examined how intracranial large artery stenosis (ILAS), symptomatic and asymptomatic ILAS, and risk factors affect unfavorable outcome events after medical treatment in routine clinical practice. Methods This was a 24-month prospective observational study of consecutively recruited stroke patients. All participants underwent magnetic resonance angiography, and their clinical characteristics were assessed. Outcome events were vascular outcome, recurrent stroke, and death. Cox regression analyses were performed to identify potential factors associated with an unfavorable outcome, which included demographic and clinical characteristics, the risk factors, and stenosis status. Results The analysis included 686 patients; among them, 371 were assessed as ILAS negative, 231 as symptomatic ILAS, and 84 as asymptomatic ILAS. Body mass index (p < .05), hypertension (p = .01), and old infarction (p = .047) were factors relating to vascular outcomes. Hypertension was the only factor for recurrent stroke (p = .035). Poor glomerular filtration rate (< 30 mL/min/1.73 m2) (p = .011) and baseline National Institutes of Health Stroke Scale scores (p < .001) were significant predictors of death. Conclusions This study extended previous results from clinical trials to a community-based cohort study by concurrently looking at the presence/absence of stenosis and a symptomatic/asymptomatic stenotic artery. Substantiated risk factors rather than the stenosis status were predominant determinants of adverse outcome. Although the degree of stenosis is often an indicator for treatment, we suggest risk factors, such as hypertension and renal dysfunction, should be monitored and intensively treated.

Abstract
Differentiated thyroid cancer (DTC) is the most frequently diagnosed thyroid cancer. With the development of the imaging technology and fine needle aspiration, early diagnosis rate of DTC is increasing. Most patients have favorable prognosis for DTC's low-invasion. TNM staging is more widely used for predicting mortality than predicting recurrence. In 2008, it was suggested that recurrence risks for DTC should be assessed based on the results of dynamic monitoring treatment response. The validity of dynamic risk stratification (DRS) has been supported by different researches in various countries and DRS is recommended in 2015 American Thyroid Association Management Guidelines. Long-term DRS in patients with DTC make individual management possible.

Abstract
Intra-abdominal varices rupture is a rare but catastrophic complication in cirrhosis. We report our near-miss experience in a woman presenting with acute abdominal pain and shock. This 55-year-old cirrhotic woman presented with sudden onset of epigastric pain. On arrival, her blood pressure was 57/49 mmHg and physical examination revealed epigastric tenderness without rebounding tenderness. Emergency ultrasonography (EUS) showed intra-abdominal haemorrhage. Computed tomography revealed haemoperitoneum but no extravasation of contrast medium. She received conservative treatment first but laparotomy later for ongoing bleeding. Surgeon identified and ligated a ruptured splenic varix and she was discharged home after nine days of hospitalisation. This case report illustrates the use of bedside EUS in cirrhotic patients presenting with acute abdominal pain. (Hong Kong j.emerg.med. 2014;21:120-123)

Abstract
Black phosphorus is a layered semiconducting allotrope of phosphorus with high carrier mobility. Its monolayer form, phosphorene, is an extremely fashionable two-dimensional material which has promising potential in transistors, optoelectronics and electronics. However, phosphorene-like analogues, especially phosphorene-based heterostructures and their layer-controlled electronic properties, are rarely systematically investigated. In this paper, the layer-dependent structural and electronic properties of phosphorene-like materials, i.e., mono- and few-layer MXs (M = Sn, Ge; X = S, Se), are first studied via first-principles calculations, and then the band edge position of these MXs as well as mono- and few-layer phosphorene are aligned. It is revealed that van der Waals heterostructures with a Moiré superstructure formed by mutual coupling among MXs and among MXs and few-layer phosphorene are able to show type-I or type-II characteristics and a I-II or II-I transition can be induced by adjusting the number of layers. Our work is expected to yield a new family of phosphorene-based semiconductor heterostructures with tunable electronic properties through altering the number of layers of the composite.

Abstract
Objective: To investigate the effect of steroid hormones on the growth and biofilm formation of S. epidermidis. Methods: In all experiments, two S. epidermidis standard strains (ATCC12228 and ATCC35984) and two S. epidermidis clinical strains (SE101 and SE40) were incubated on the surface of silica gel in estradiol concentrations of 0, 50, 125, 250 and 500 pmol/L at 4, 6, 12, 24, 48 and 72 hours. Growth curve were drawn by means of the OD value. Formed biofilms were assessed by crystal violet staining methods. In order to observe the processes and structures of biofilm, the confocal laser scanning microscopy (CLSM) and scanning electron microscope (SEM) were used. Results: All of the four strains which were incubated with the concentrations of 125 pmol/L of estradiol had entered the logarithmic growth stage ahead of the blank control (3 h and 4 h). Crystal violet staining indicated that there was no biofilm for ATCC12228. Improved primary attachment abilities were found for ATCC35984 and SE101 in the presence of estradiol, and the OD values were 0 pmol/L (0.081±0.015 and 0.082±0.011), 50 pmol /L (0.087±0.013 and 0.088±0.010), 125 pmol/L (0.175±0.052 and 0.091±0.012), 250 pmol/L (0.153±0.036 and 0.090±0.006), 500 pmol/L (0.157±0.050 and 0.082±0.032), respectively. The thickness of biofilm reached the peak in 125 pmol/L estradiol at 24 h. CLSM and SEM found estradiol promoted the biofilm maturity and the biofilm of 125 pmol/L group was denser and thicker than that of the other concentration groups. Conclusions: Our in vitro experiments indicate that estradiol could promote the growth of S. epidermidis which exit on the surface of silica gel, and improve the ability of biofilm formation of S. epidermidis.

Abstract
Objective:To compare the near and long term efficacy and safety of paclitaxel(TAX) plus cisplatin(DDP) (TP regimen) and DDP plus 5-FU(PF regimen) concurrently combined with IMRT in treatment of patients with advanced NPC.Method: A retrospective analysis on 108 advanced NPC cases from January 2010 to December 2012 was conducted. The patients were divided into TP group(57 cases) and PF group(51 cases) according to therapy regimen. TP group received IMRT combined with TP therapy, and PF group received IMRT combined with PF regimen, two groups were both used 4 cycles of chemotherapy, toxicity reactions during concurrent radiochemotherapy were noted. Two months after treatment, near clinical efficacies of the two groups were determined, and then, a three years followingup was conducted, during which recurrence ratio, metastasis ratio, local control ratio and survival rate were analyzed. Result: Two months after treatment, the total effective ratio of TP group(84.2% vs.76.5%) was higher than PF group,however, the difference was not statistically significant(P>0.05). Gastrointestinal reaction(70.2% vs.66.7%), marrow inhibition(75.4% vs.82.4%), liver function damage(12.3% vs.13.7%), radioactive oral and pharyngeal injury(91.2% vs.98.0%), hearing damage(15.8% vs.15.7%) in the two groups during chemoradiotherapy had no significant differences(P>0.05). During followingup, the recurrence and metastasis ratio in TP group(33.3% vs.47.1%) was lower than PF group(χ²=2.116,P=0.146). TP group with The local control rate(73.7% vs.68.5%) and survival rate(84.2% vs.78.4%) after three years treatment in TP group were higher than PF group(χ²=0.336,P=0.562;χ²=0.596,P=0.440). Conclusion: IMRT concurrently combined with TP and PF respectively are both effective methods for treatment of advanced NPC. In this study, IMPT plus TP concurrent chemoradiotherapy has a certain superiority in near and long term clinical treatment efficacy and safety.

Abstract
In this study, we investigated a fluidic system that adheres to new concepts of energy production. To improve efficiency, cost, and ease of manufacture, a millimetrically scaled device that employs a droplet-based co-axial fluidic system was devised to complete alkali-catalyzed transesterification for biodiesel production. The large surface-to-volume ratio of the droplet-based system, and the internal circulation induced inside the moving droplets, significantly enhanced the reaction rate of immiscible liquids used here – soybean oil and methanol. This device also decreased the molar ratio between methanol and oil to near the stoichiometric coefficients of a balanced chemical equation, which enhanced the total biodiesel volume produced, and decreased the costs of purification and recovery of excess methanol. In this work, the droplet-based co-axial fluidic system performed better than other methods of continuous-flow production. We achieved an efficiency that is much greater than that of reported systems. This study demonstrated the high potential of droplet-based fluidic chips for energy production. The small energy consumption and low cost of the highly purified biodiesel transesterification system described conforms to the requirements of distributed energy (inexpensive production on a moderate scale) in the world.

Abstract
Streptococcal infections cause significant mortality and high economic losses in the fish farm industry worldwide, including in the culture of golden pompano Trachinotus ovatus L., a species gaining popularity in China. A total of 9 streptococcal strains were isolated from cage-cultured diseased golden pompano in Beihai, Zhanjing, and Shenzhen, China, between 2012 and 2014. Conventional and rapid identification systems were used to determine that the isolates were Streptococcus agalactiae, S. iniae, and S. dysgalactiae subsp. dysgalactiae. All isolates were gram-positive cocci cells in pairs or short-chain, non-motile, catalase negative, α or β hemolytic cocci. The results of multiplex PCR assays and 16S rRNA BLAST analysis also showed that the β hemolytic strains were S. agalactiae and S. iniae and the α hemolytic strain was S. dysgalactiae subsp. dysgalactiae, respectively. Pathogenicity assays revealed that S. agalactiae (lethal dose [LD50]: 6.38 × 10(4) CFU ml(-1)) was more virulent for golden pompano than S. iniae (LD50: 1.47 × 10(7) CFU ml(-1)) and S. dysgalactiae subsp. dysgalactiae (LD50: 2.57 × 10(6) CFU ml(-1)) when they were challenged by intraperiotoneal (i.p.) injection. The results of antibiotic susceptibility showed that all strains were extremely susceptible to cefradine, erythromycin, and cefotaxime but resistant to gentamicin, penicillin G, novobiocin, neomycin, ciprofloxacin, roxithromycin, furazolidone, enrofloxacin, norfloxacin, kanamycin, ampicillin, tetracycline, and vancomycin This is the first report of a phenomenon of golden pompano coinfection with S. agalactiae and S. iniae, which will contribute to the diagnosis and prevention of streptococcicosis.

Abstract
PURPOSE This study aimed to further investigate the effects of agmatine on brain edema in the rats with middle cerebral artery occlusion (MCAO) injury using magnetic resonance imaging (MRI) monitoring and biochemical and histopathologic evaluation. MATERIALS AND METHODS Following surgical induction of MCAO for 90min, agmatine was injected 5min after beginning of reperfusion and again once daily for the next 3 post-operative days. The events during ischemia and reperfusion were investigated by T2-weighted images (T2WI), serial diffusion-weighted images (DWI), calculated apparent diffusion coefficient (ADC) maps and contrast-enhanced T1-weighted images (CE-T1WI) during 3h-72h in a 1.5T Siemens MAGNETON Avanto Scanner. Lesion volumes were analyzed in a blinded and randomized manner. Triphenyltetrazolium chloride (TTC), Nissl, and Evans Blue stainings were performed at the corresponding sections. RESULTS Increased lesion volumes derived from T2WI, DWI, ADC, CE-T1WI, and TTC all were noted at 3h and peaked at 24h-48h after MCAO injury. TTC-derived infarct volumes were not significantly different from the T2WI, DWI-, and CE-T1WI-derived lesion volumes at the last imaging time (72h) point except for significantly smaller ADC lesions in the MCAO model (P<0.05). Volumetric calculation based on TTC-derived infarct also correlated significantly stronger to volumetric calculation based on last imaging time point derived on T2WI, DWI or CE-T1WI than ADC (P<0.05). At the last imaging time point, a significant increase in Evans Blue extravasation and a significant decrease in Nissl-positive cells numbers were noted in the vehicle-treated MCAO injured animals. The lesion volumes derived from T2WI, DWI, CE-T1WI, and Evans blue extravasation as well as the reduced numbers of Nissl-positive cells were all significantly attenuated in the agmatine-treated rats compared with the control ischemia rats (P<0.05). CONCLUSION Our results suggest that agmatine has neuroprotective effects against brain edema on a reperfusion model after transient cerebral ischemia.

Abstract
Color patterns of bird plumage affect animal behavior and speciation. Diverse patterns are present in different species and within the individual. Here, we study the cellular and molecular basis of feather pigment pattern formation. Melanocyte progenitors are distributed as a horizontal ring in the proximal follicle, sending melanocytes vertically up into the epithelial cylinder, which gradually emerges as feathers grow. Different pigment patterns form by modulating the presence, arrangement, or differentiation of melanocytes. A layer of peripheral pulp further regulates pigmentation via patterned agouti expression. Lifetime feather cyclic regeneration resets pigment patterns for physiological needs. Thus, the evolution of stem cell niche topology allows complex pigment patterning through combinatorial co-option of simple regulatory mechanisms.

Abstract
BACKGROUND Migrating motor complex phase III (MMC phase III) of intestine is an important physiological mechanism traditionally recognized by myoelectric recordings or pressure tracings. Direct imaging is difficult and sonographic visualization in human has not been reported. METHODS We have demonstrated this unique phenomenon in three patients who underwent abdominal sonographic examinations. Characteristic images were recorded by videotape and both spatial and temporal features were analyzed. KEY RESULTS Occurrences of multiple equally spaced, rhythmic intestinal contractions were observed. Parameters including wave frequency, propagation velocity, and duration of the events agreed with those of the well-known phase III. The presence of distinct cyclic patterns observed in two and abolition by meal in the other patient further support our conclusion. CONCLUSIONS & INFERENCES We conclude that the migrating waves observed in our study represent the human MMC phase III. This unique finding in human subjects merits further investigation.

Abstract
Amelogenins are the major constituent of developing extracellular enamel matrix proteins and are understood to have an exclusively epithelial origin. Recent studies have demonstrated that amelogenins can be detected in other tissues, including bone marrow mesenchymal stem cells (MSCs), but the role of amelogenins in MSCs remains unclear. The purpose of this study was to examine the effect of recombinant human full-length amelogenin (rh174) on the osteogenic differentiation of cultured human MSCs. MSCs isolated from human bone marrow were cultured in osteoblastic differentiation medium with 0, 10 or 100 ng/ml rh174. The mRNA levels of bone markers were examined by real-time PCR analysis. Alkaline phosphatase (ALP) activity and calcium concentration were determined. Mineralization was evaluated by alizarin red staining. The mRNA levels of ALP, type I collagen, osteopontin and bone sialoprotein in the MSCs treated with rh174 became significantly higher than those in non-treated controls. Treatment of MSCs with rh174 also enhanced ALP activity and calcium concentration, resulting in enhanced mineralization, as denoted by high intensity of alizarin red staining. In conclusion, the present study showed that rh174 enhances the mineralization accompanied by the upregulation of bone markers in human bone marrow MSCs during osteogenic differentiation, suggesting a certain role of amelogenin in the modulation of osteogenic differentiation of MSCs.

Abstract
BACKGROUND A parasitological survey of Schistosoma haematobium and S. intercalatum infection among primary schoolchildren in capital area of Democratic Republic of São Tomé and Príncipe (DRSTP) was undertaken. METHODS Subjects with positive infection were confirmed by the detection of S. haematobium ova in the urine or S. intercalatum ova in the stool by using centrifugation concentration or merthiolate-iodine-formalin concentration method. Totally, 252 urine and stool samples, respectively, were obtained from apparently healthy schoolchildren, of which 121 from boys (9.8 ± 1.4 yr) and 131 from girls (9.7 ± 1.3 yr). RESULTS None of participating schoolchildren were found having S. haematobium ova in the urinary specimen. While, among 4 primary schools studied, only schoolchildren from Saint Marçal were detected with S. intercalatum ova in the fecal specimen, making the overall prevalence of S. intercalatum infection among schoolchildren was 2.4% (6/252) and girls had insignificantly higher prevalence (3.1%, 4/131) than that (1.7%, 2/121) in boys (χ(2) = 0.5, P = 0.5). CONCLUSION Water control and sanitation as well as snails eliminated by molluscicides are urgently needed to reduce S. intercalatum infection in DRSTP inhabitants.

Abstract
We report on a tunable intracavity optical parametric oscillator (IOPO) achieved using a two-dimensional (2D) periodically poled lithium niobate (PPLN) as simultaneously an electro-optic (EO) Bragg Q-switch and an optical frequency mixer (OFM) in a diode-pumped Nd:YVO(4) laser. The 2D periodic domain inversion structure is designed to provide two orthogonal reciprocal vectors to respectively satisfy the phase-matching conditions required by the two quasi-phase-matching devices (i.e., the PPLN EO Bragg deflector and the PPLN OFM). At a ~140-V Q-switching voltage and a 1-kHz switching rate, we obtained a signal wave at 1550 nm with a pulse energy of 9.7 μJ (corresponding to a peak power of ~2.4 kW) from the IOPO at 9.1-W diode pump power. Simultaneously we also observed multi-wavelength generation from the system originating in the single-pass parametric conversions in the 2D nonlinear photonic crystal structure. Temperature tuning of the IOPO signal wavelength in the eye-safe region was also demonstrated.

Abstract
BACKGROUND AND PURPOSE Caffeine is consumed extensively in Europe and North America. As a risk factor for osteoporosis, epidemiological studies have observed that caffeine can decrease bone mineral density, adversely affect calcium absorption and increase the risk of bone fracture. However, the exact mechanisms have not been fully investigated. Here, we examined the effects of caffeine on the viability and osteogenesis of rat bone marrow-derived mesenchymal stromal cells (rBMSCs). EXPERIMENTAL APPROACH Cell viability, apoptosis and necrosis were quantified using thymidine incorporation and flow cytometry. Sequential gene expressions in osteogenic process were measured by real-time PCR. cAMP, alkaline phosphatase and osteocalcin were assessed by immunoassay, spectrophotometry and radioimmunoassay, respectively. Mineralization was determined by calcium deposition. KEY RESULTS After treating BMSCs with high caffeine concentrations (0.1-1mM), their viability decreased in a concentration-dependent manner. This cell death was primarily due to necrosis and, to a small extent, apoptosis. Genes and protein sequentially expressed in osteogenesis, including Cbfa1/Runx2, collagen I, alkaline phosphatase and its protein, were significantly downregulated except for osteocalcin and its protein. Moreover, caffeine inhibited calcium deposition in a concentration- and time-dependent manner, but increased intracellular cAMP in a concentration-dependent manner. CONCLUSIONS AND IMPLICATIONS By suppressing the commitment of BMSCs to the osteogenic lineage and selectively inhibiting gene expression, caffeine downregulated some important events in osteogenesis and ultimately affected bone mass.

Abstract
Rheumatoid arthritis (RA) is a chronic autoimmune disease and can lead to deformities and severe disabilities, due to irreversible damage of tendons, joints, and bones. A previous study indicated that a DNA repair system was involved in the development of RA. In this study, we investigated the association of four N-methylpurine-DNA glycosylase (MPG) gene polymorphisms (rs3176364, rs710079, rs2858056, and rs2541632) with susceptibility to RA in 384 Taiwanese individuals (192 RA patients and 192 control subjects). Our data show a statistically significant difference in genotype frequency distributions at rs710079 and rs2858056 SNPs between RA patients and control groups (P = 0.040 and 0.029, respectively). Our data also indicated that individuals with the GG genotype at rs2858056 SNP may have a higher risk of developing RA. In addition, compared with the haplotype frequencies between case and control groups, individuals with the GCGC haplotype appeared to be at a greater risk of RA progression (P = 0.003, OR = 1.75; 95% CI = 1.20-1.55). Our results suggest that rs710079 and rs2858056 polymorphisms and the GCGC haplotype in the MPG gene are associated with the risk of RA progression, and thus may be used as molecular markers of RA if they are confirmed by further research.

Abstract
Speckle-based methods have been developed to characterize tissue blood flow and perfusion. One such method, called modified laser speckle imaging (mLSI), enables computation of blood flow maps with relatively high spatial resolution. Although it is known that the sensitivity and noise in LSI measurements depend on image exposure time, a fundamental disadvantage of mLSI is that it does not take into account this parameter. In this work, we integrate the exposure time into the mLSI method and provide experimental support of our approach with measurements from an in vitro flow phantom.

Abstract
There is no generally accepted definition for a "prolonged surgical intensive care unit (SICU) stay". The aims of the current study were to: (1) define prolonged SICU stay; (2) identify risk factors of prolonged SICU stay; and (3) identify risk factors of hospital mortality in patients with a prolonged SICU stay. All SICU patients aged >16 years and with an intensive care unit (ICU) stay longer than three days without ICU readmission between 1 January 2004 and 30 November 2006 at the National Taiwan University Hospital were recruited to the study. A total of 2598 patients were recruited. ICU stay >16 days was defined as a prolonged SICU stay since rates of ICU mortality, hospital mortality and mortality one year after ICU discharge remained stationary after ICU stay was >16 days. A multivariate logistic regression model identified factors associated with a prolonged SICU stay, including age more than 70 years old, (odds ratio 1.587, 95% confidence interval 1.246 to 2.022), increasing pre-ICU hospital days (odds ratio 1.009, 95% confidence interval 1.003 to 1.015), admission from emergency (odds ratio 1.925, 95% confidence interval 1.455 to 2.548), use of mechanical circulation support (odds ratio 2.314, 95% confidence interval 1.458 to 3.674) and renal replacement therapy (odds ratio 5.140, 95% confidence interval 3.781 to 6.987). A multivariate logistic regression model identified factors associated with ICU mortality in patients with ICU stay >16 days, including renal replacement therapy (odds ratio 4.780, 95% confidence interval 2.687 to 8.504). An ICU stay >16 days could be used to define prolonged SICU stay when hospital and one-year mortality rates are considered. Prevention of organ failure requiring renal replacement therapy might prove a useful goal to avoid prolonged ICU stay and even hospital mortality.

Abstract
AIMS The purpose of this study was to develop a loop-mediated isothermal amplification (LAMP) method for the rapid, sensitive and simple detection of Vibrio alginolyticus in mariculture fish. METHODS AND RESULTS LAMP primers were designed by targeting the gyrB gene. With Bst DNA polymerase, the target DNA can be clearly amplified for 60 min at 64 degrees C in a simple water bath. The detection sensitivity of the LAMP assay for the detection of V. alginolyticus is about 3.7 x 10(2) CFU ml(-1) (3.7 CFU per reaction). LAMP products could be judged with agar gel or naked eye after the addition of SYBR Green I. There were no cross-reactions with other bacterial strains indicating a high specificity of the LAMP. The LAMP method was applied to detect V. alginolyticus-infected fish tissues effectively. CONCLUSIONS The LAMP established in this study is a simple, sensitive, specific, inexpensive and rapid protocol for the detection of V. alginolyticus. SIGNIFICANCE AND IMPACT OF THE STUDY This LAMP method provides an important diagnostic tool for the detection of V. alginolyticus infection both in the laboratory and field.

Abstract
We report a CW, watt-level, red, green, and blue (RGB) laser pumped by an economical multimode (1-nm linewidth) Yb-fiber laser at 1.064 mum. A singly resonant optical parametric oscillator at 1.56 mum has two intracavity sum-frequency generators for red and blue laser generation. An extracavity second harmonic generator converts the residual pump power into green laser radiation. At 25-W pump power, the laser generated 3.9, 0.456, and 0.49 W at 633, 532, and 450 nm, respectively. The multimode pump laser offers a large temperature bandwidth for operating the RGB OPO without the need of a precision crystal temperature stabilizer.

Abstract
We report a mid-infrared, CW singly resonant optical parametric oscillator (OPO) with a thermally induced waveguide in its gain crystal. We measured a numerical aperture of 0.0062 for the waveguide at 80-W intracavity power at 3.2 microm. This thermal-guiding effect benefits to the stable operation of an OPO and improves the parametric conversion efficiency by more than a factor of two when compared with that without thermal guiding.
