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

Abstract
In recent years, osteoporosis (OP) has become one of the main diseases affecting the health of middle-aged and elderly people in China, and the prevalence of OP has increased significantly. The clinical diagnosis and treatment guidelines for this disease are also constantly updated. The overall principles speciallyemphasise that doctors and patients need to work together to negotiate the details of the diagnosis and treatment guidelines, in order to improve the OP clinical diagnosis and treatment rate. Therefore, patients' knowledge of the disease, understanding of clinical guidelines, and cooperation with doctors to implement diagnosis and treatment plans are very important. In this study, from the most concerned issues of the patients, we established the OP patient practice guideline working group. 14 recommendations, as the OP patient practice guidelines, are proposed in accordance with the relevant principles of the "World Health Organization guidelines development manual" and the international normative process.

Abstract
Objective: To analyze the characteristics of vessel density in the optic disc and macular area of patients with different phases of thyroid-associated ophthalmopathy (TAO) and their correlation with visual function. Methods: This case-control study was conducted at the Department of Ophthalmology of Peking Union Medical College Hospital between June 2019 and September 2019. TAO patients and healthy volunteers were included in the study. Patients with a clinical activity score greater than or equal to 3 points were categorized as active TAO. Dysthyroid optic neuropathy (DON) patients with a course less than 6 months were categorized as acute phase of DON, and those more than 6 months were in the chronic group. Healthy volunteers were in the control group. Each group included 12 subjects, with right eyes for analysis. There were 6 males and 6 females in each group. All participants underwent comprehensive ophthalmic examination including best corrected visual acuity and visual field examination for the mean defect (MD). Best corrected visual acuity was subsequently converted to logarithm of minimum angle of resolution (logMAR). Optical coherence tomography was used to measure the thickness of the retinal nerve fiber layer (RNFL) and retinal ganglion cell complex (GCC). Optical coherence tomography angiography was used to the peripapillary and macular vessel density. The differences in the vessel densities in the optic disc and macular area between groups and their correlation with different factors were analyzed. Analysis of variance, non-parametric Mann-Whitney U test and Spearman coefficient were conducted for statistical analysis. Results: There was no significant difference in age among the four groups (P>0.05). The logMAR of the acute DON group was 0.1 (0.0, 0.2), worse than the control group, which was 0.0 (0.0, 0.0) (U=114.000, P<0.05). The overall vessel densities of the optic disc in acute DON and chronic DON were significantly lower than the control group (54.70%±2.31% and 54.31%±3.65% vs. 57.54%±2.17%; t=3.104, 2.636; both P<0.05). The overall superficial vessel densities of the macular area in active TAO, acute DON and chronic DON were significantly lower than the control group (46.07%±3.06% and 42.26%±5.05% and 45.63%±3.87% vs. 49.34%±3.08%), and the differences were statistically significant (t=2.614, 4.147, 2.603; all P<0.05). There was no statistically significant difference in the size of the foveal avascular zone or the density of deep blood vessels in the macular area among the four groups (all P>0.05). In the active TAO period, there was no correlation between the MD value, RNFL thickness, GCC thickness and the vessel densities of the optic disc and macular area (all P>0.05). The vascular density of the whole layer of the optic disc in acute DON was negatively correlated with the MD value (r=-0.591, P<0.05) and positively correlated with the RNFL thickness and GCC thickness (r=0.595, 0.693; both P<0.05). In chronic DON, the overall capillary density of the optic disc was negatively correlated with the MD value (r=-0.673, P<0.05); the superficial overall blood vessel density of the macular area was positively correlated with the thickness of RNFL and GCC (r=0.732, 0.712;both P<0.01). Conclusions: In active TAO, only the blood supply to the superficial layer of the macular area is decreased. In the acute and chronic phases of DON, the blood supply to the superficial layer of the macular area and the optic disc is both reduced; the smaller the blood vessel density, the more severe the visual field defect, and the thinner the RNFL and GCC.

Abstract
Objective: To explore the relationship between the quality of professional life and depression tendency of nurses. Methods: From November 2018 to January 2019, 242 nurses from some third-class A hospitals were randomly selected as the subjects. The Quality of Professional Life Scale of Nurses were used to evaluate the status of nurses' professional life quality, and the depression state of nurses was measured by Self Rating Depression Scale, and the relationship between them was analyzed. Results: The total score of professional life of nurses was (156.86±26.60) , including family work balance (24.60±4.73) , working environment (77.30±14.78) , workload (36.34±6.11) and social environment (18.62±4.21) . The total score of depression tendency of nurses was (43.76±9.50) , the overall depression tendency rate was 64.46% (156/242) , and the incidence rates of moderate and severe depression tendency were 23.55% (57/242) and 10.74% (26/242) , respectively. There was negative correlation between the total score of professional quality of life and each dimension score with depression tendency (P<0.05) ; Multiple linear regression analysis showed that high quality of professional life was the protective factor of depression tendency of nurses (P<0.001) . Conclusion: The quality of professional life of nurses is related to depression tendency, and the high quality of professional life is not prone to depression.

[PMID: 32867991 PMCID: PMC7598098 DOI: 10.1016/j.psj.2020.05.047] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2019] [Revised: 04/27/2020] [Accepted: 05/22/2020] [Indexed: 01/22/2023] Open
Abstract
This study was conducted to explore the regulatory role of methionine (Met) in feather follicle and feather development during the embryonic period of chicks. A total of 280 fertile eggs (40 eggs/group) were injected with 0, 5, 10, 20 mg of L-Met or DL-Met/per egg on embryonic day 9 (E9), and whole-body feather and skin tissues were collected on E15 and the day of hatching (DOH). The whole-body feather weight was determined to describe the feather growth, and the skin samples were subjected to hematoxylin and eosin staining and Western blotting for the evaluation of feather follicle development and the expressions of Wingless/Int (Wnt)/β-catenin signaling pathway proteins, respectively. The results showed that L- or DL-Met did not affect the embryo weight (P > 0.05), but increased the absolute and relative whole-body feather weights. Specifically, 5 and 10 mg of L-Met and 5, 10, and 20 mg of DL-Met significantly increased the absolute feather weight at E15 (P < 0.05), and 10 mg of L-Met and 5 and 10 mg of DL-Met significantly increased the absolute and relative feather weight on the DOH (P < 0.05). Moreover, a main effect analysis suggested that changes in the embryo and feather weights were related to the Met levels (P < 0.05) but not the Met source (P > 0.05). The levels of L- and DL-Met were quadratically correlated with the absolute and relative feather weights of chicks on the DOH (P < 0.05). Correspondingly, all doses of L- and DL-Met significantly increased the diameter and density of feather follicles on the DOH (P < 0.05), as well as the activity of Wnt/β-catenin on E15 and the DOH (P < 0.05). In conclusion, injection of either L- or DL-Met can improve feather follicle development by activating Wnt/β-catenin signaling, and thereby promoting feather growth; furthermore, no difference in feather growth was found between L- and DL-Met treatments. Our findings might provide a nutritional intervention for regulating feather growth in poultry production.

Abstract
Objective: To investigate secondary factors, laboratory features, treatment options, and prognosis of pure red cell aplastic anemia (PRCA) . Methods: This was a multicenter retrospective clinical study. Patients aged above 18 years newly diagnosed with PRCA between June 1, 2010, and June 1, 2019, were recruited as the main study object. A comparative analysis of remission rate and overall survival rate was made according to different treatment schemes adopted by patients and different drug reduction rates. Results: A total of 67 patients with PRCA were included in this study and the secondary PRCA group accounted for 44.8% (30/67) . The most common secondary factors were thymoma (n=10) and T-cell large lymphocytic leukemia (T-LGLL) (n=6) . The overall response rate of PRCA was 85.7% and the 3-year overall survival rate of PRCA was (74.3±7.5) %. The remission rate of cyclosporine A alone was slightly higher than that of oral glucocorticoid alone or combined with glucocorticoid[90.0% (36/40) vs 75.0% (12/16) , P=0.147]. After patients applied with cyclosporine A treatment reached CR/PR and remained stable for 3-6 months, the dose of cyclosporine A was reduced by 25 mg each time. The cyclosporine A reduction interval of a 25 mg/d reduction in more than 1 month significantly prolonged the median disease-free survival compared with a 25 mg/d reduction in less than 1 month [not reached vs 15 (95% CI 7-23) months, P<0.001]. There were 62.5% (10/16) of patients who responded to the initial or incremental treatment regimen after relapse. Conclusion: PRCA has features of various secondary factors, high overall survival rate, and high remission rate. Treatment with cyclosporine A alone is preferred, and cyclosporine A should be slowly tapered to reduce the risk of later relapse after it takes effect and patients reach a steady state.

Abstract
OBJECTIVE To investigate the diagnosis and surgical treatment of co-infection with hepatic cystic and alveolar echinococcosis, so as to provide insights into the diagnosis and treatment of these patients. METHODS The clinical data of patients with co-infections of hepatic cystic and alveolar echinococcosis in Qinghai Provincial People's Hospital between 2017 and 2018 were retrospectively analyzed. RESULTS Three patients were diagnosed with co-infection of hepatic cystic and alveolar echinococcosis. One patient was diagnosed by preoperative CT scan, and confirmed intraoperatively. The other two cases were diagnosed as cystic echinococcosis by preoperative color ultrasonography and imaging examinations, and were definitively diagnosed as co-infection of hepatic cystic and alveolar echinococcosis by intraoperative examination of the lesion morphology and postoperative pathology. Two patients were given radical surgery, and another case was given removal of the internal capsule and subtotal excision of the outer capsule of Echinococcus granulous in the liver following exploration. CONCLUSIONS Co-infection with hepatic cystic and alveolar echinococcosis is easy for missed diagnosis and misdiagnosis prior to operation, and the definitive diagnosis may be made by means of imaging examinations combined with postoperative pathology. The surgery is relatively complicated and difficult for patients with co-infection of hepatic cystic and alveolar echinococcosis, and individualized surgical treatment regimen should be employed for patients with various types of infections.

Abstract
Objective: To analyze the clinical characteristics of 34 COVID-19 cases and to provide the basis for the prevention and control of the epidemic disease. Methods: Thirty-four COVID-19 patients diagnosed with RT-PCR in the isolation ward of the Fourth People's Hospital of Ningxia Hui autonomous region (infectious diseases hospital) from the January 22 to February 4, 2020 were selected as the research subjects. The clinical data were collected. Excel was used to describe the relationship between clinical classification and age distribution, contact history and date of onset. SPSS 25.0 statistical software was used for analysis. The general information, clinical symptoms, blood test, virus nucleic acid test results, epidemiology, CT imaging, treatment and prognosis were analyzed. Results: There were 5 mild cases (5/34), 24 ordinary cases (24/34), 5 severe cases (5/34). The elderly was more common in severe patients. The main clinical symptoms were fever (27/34)and dry cough(26/34). The peripheral blood showed normal or decreased leukocyte count (33/34), decreased lymphocyte count (12/34). The increase of C-reactive protein (CRP) and D-dimer was related to the severity of the disease. Some patients had mild liver and kidney damage. Six patients were diagnosed through 3 or more times of nucleic acid tests. Sixteen cases had Wuhan related history,13 cases were close contacts, 5 cases had no confirmed route. The clustered infections were found in 6 families. In typical cases, CT showed single or multiple patchy ground glass shadow with thickening of interlobular septum. In severe cases, diffuse lesions of both lungs were found, with ground glass shadow, consolidation shadow and strip shadow coexisting. Thirty-four patients were treated with interferon-α and Lopinavir/Ritonavir with good prognosis. Conclusions: The clinical characteristics of COVID-19 were similar to that of general viral pneumonia but with strong infectivity. Close contact and family aggregation caused disease outbreaks. COVID-19 could not be excluded if two nucleic acid tests were negative and high-resolution CT was helpful for differential diagnosis. Early detection, early isolation, early diagnosis and early treatment are important for good prognosis. The effectiveness of antiviral drugs needs to be further verified.

Abstract
1. This study investigated the pattern of feather follicle morphogenesis and the expression of the Wnt/β-catenin signalling pathway in the skin of yellow-feathered broiler chick embryos during feather development, using haematoxylin and eosin (H&E) staining and Western blot assays, respectively. 2. The results showed that the skin displayed protrusions during embryonic days E7-E9, feather buds elongated during E10-E11 with anterior-posterior and proximal-distal asymmetries, and the epidermis invaginated to form the primary feather follicles (Pfs) at E12. At E13, the formation of the feather follicle and the epidermis at the base of the feather bud further invaginated into the dermis. By E15, Pf formation was essentially complete, and secondary feather follicles (Sfs) appeared. It was speculated that Pfs and Sfs developed independently and that Pfs occurred earlier than Sfs. 3. Quantitative measurements of Pf density reached a maximum at E15 and then decreased gradually. Sf density started to increase from E15. 4. Protein expression levels of β-catenin, TCF4, cyclin D1, and c-Myc were significantly increased during E8-E12 (P < 0.05) and then decreased from E13 to the day of hatching (DOH) (P < 0.05). The result of the β-catenin immunolocalisation signal intensity assay was consistent with the result of the Western blot assay. 5. Collectively, the results indicated that the Wnt/β-catenin signalling pathway is essential for promoting the development of feather follicles, especially during E7-E15.

Abstract
Objective: To observe the safety and efficacy of lenvatinib for the treatment of medium-advanced hepatocellular carcinoma. Methods: A total of 36 patients with medium-advanced hepatocellular carcinoma from the First Medical Center of the Chinese PLA General Hospital were retrospectively analyzed from January 2018 to May 2019. All patients had shown tumor progression after at least 2 sessions of TACE. The patients were consisted of 30 males and 6 females with age range of 35 to 76 (54±10) years. Patients received orally administered lenvatinib at a dose of 12 mg once daily for patients ≥ 60 kg and 8 mg once daily for patients<60 kg. According to modified RECIST criteria the tumor response, disease control rate, overall survival and progression free survival were evaluated once every 6-8 weeks. The adverse events were recorded. Results: No patient was in complete response, 2 cases (5.7%) in partial response, and 5 cases (14.3%) in stable disease, respectively. Disease control rate was 20.0% (7/35), the overall survival was 11.5 months, and the progression free survival was 5.3 months. The overall incidence of adverse events was 66.7% (24/36). The most frequent adverse events were hypertension, proteinuria, hand-foot skin reaction and abdominal distension. Conclusion: Lenvatinib can extend the overall survival in a percentage of medium-advanced hepatocellular carcinoma patients who were unresectable and refractory to TACE. Although the incidence of adverse events is high, most of them are mild and reversible.

Abstract
This study aimed to explore the effects of Shenyuan granules on the Klotho/FGFR23/Egr1 signaling pathway and calcium-phosphorus metabolism in diabetic mice models with impairment of renal function. Streptozotocin-induced diabetic nephropathy (DN) mice models were randomly divided into three groups: Shenyuan granules group (n=10), model control group (n=10), and blank control group (n=10). Corresponding drugs were given by gavage for 8 weeks. Blood glucose and serum creatinine (SCr), urea nitrogen (BUN), calcium (Ca), phosphorus (P) and mLAB were detected before and after administration. Moreover, RT-qPCR was performed to detect the expression of CYP24 and CYP27 mRNA in kidney tissue. Blood FGF23 was detected by ELISA. Western-blot and immunohistochemistry were performed to detect the expressions of Klotho, FGFR1, Egr1, CYP24, CYP27, ERK1/2 and p-ERK1/2. Compared with the blank control group, in the model control group serum FGF23,P, SCr and 24-hour proteinuria levels increased (P<0.05), serum Ca significantly decreased (P<0.05), expressionss of Egr1, CYP24, CYP27 and p-ERK1/2 were up-regulated (P<0.05), and the expressions of Klotho and FGFR1 were down-regulated (P<0.05). After treatment, compared with the model control group, in the Shenyuan granule group serum FGF23, P, SCr levels decreased (P<0.05), serum Ca increased (P<0.05), expressions of Egr-1, CYP24, CYP27 and p-ERK1/2 were down-regulated (P<0.05), and the expressions of Klotho and FGFR1 were up-regulated (P<0.05). Shenyuan granules may partly intervene in the expressions of CYP24 and CYP27 through the Klotho/FGF23/Egr1 signaling pathway, thereby improving calcium and phosphorus metabolism and alleviating renal injury in diabetic nephropathy.

Abstract
Leucine (Leu) plays a critical regulatory role in protein synthesis, however, the effects and molecular mechanisms of Leu on crop milk protein in the domestic pigeons (Columba livia) are still unknown. Therefore, the study aimed to investigate the effects of dietary Leu supplementation on crop milk protein synthesis and the growth performance of squabs and the possible underlying mechanism. A total of 240 pairs of breeding pigeons (1102.3 ± 9.5 g/pair) were randomly assigned to 1 of 5 treatments, including a positive control (PC) diet that had adequate crude protein (crude protein, CP = 18%; Leu = 1.30%), a negative control (NC) diet that was low in CP (CP = 16%, Leu = 1.30%), and NC diets supplemented with Leu at 0.15%, 0.45%, or 1.05%. Compared with the NC diet, 0.15 to 0.45% Leu supplementation decreased BW loss and increased relative crop weight, crop thickness, and protein levels in the crop tissue and milk of breeding pigeons. However, dietary supplementation with 1.05% Leu inhibited ADFI in breeding pigeons. Dietary supplementation with 0.15 to 0.45% Leu decreased the mortality rate and increased the BW, eviscerated yield, and breast muscle yield of young squabs. The protein expression levels of the target of rapamycin (TOR), ribosomal protein S6 kinase 1 (S6K1), ribosomal protein S6 kinase (S6), eukaryotic initiation factor 4E binding protein 1 (4EBP1), and eukaryotic translation initiation factor 4E (eIF4E) were upregulated in the crop tissue of breeding pigeons in PC, 0.15% and 0.45% Leu-supplemented groups. Collectively, these results indicated that 0.15 to 0.45% Leu supplementation could decrease BW loss, increase milk protein synthesis in the crop of breeding pigeons, and enhance the survival rate and growth performance of young squabs through the TOR signaling pathway.

Abstract
This study was conducted to explore the regulatory role of the target of rapamycin complex 1 (TORC1) signaling pathway in crop milk synthesis in breeding pigeons (Columba livia). Three groups of breeding pigeons in the lactation period (n = 30 pairs/group) were respectively injected with rapamycin (RAPA, a specific inhibitor of the target of rapamycin complex) at doses of 0 (vehicle, control), 0.6, or 1.2 mg/kg body weight (BW)/day via the wing vein for 7 days. The average daily feed intake (ADFI) and BW of the breeding pigeons and the BW of young squabs were respectively recorded throughout the experimental period. The breeding pigeons were sacrificed to collect their crop tissues, crop milk, and serum on the eighth day of the experiment. The results showed that neither 0.6 nor 1.2 mg/kg BW RAPA injection affected BW loss or ADFI in breeding pigeons (P > 0.05), while crop thickness and crop relative weight were significantly decreased (P < 0.05) in the 1.2 mg/kg BW rapamycin-injected group. Simultaneously, RAPA (especially at 1.2 mg/kg BW) decreased the crude protein, αs1-casein, αs2-casein, β-casein, and amino acid contents (Asp, Thr, Ser, Glu, Gly, Ala, Cys, Val, Met, Ile, Leu, Tyr, Lys, His, Arg, and Pro) of crop milk (P < 0.05) and the concentrations of albumin, total protein, and uric acid in the serum of breeding pigeons (P < 0.05). Additionally, the expression of TORC1 pathway-related proteins (TORC1, S6K1, S6, 4EBP1, and eIF4E) was downregulated in the crop tissues of breeding pigeons by 0.6 or 1.2 mg/kg BW/day RAPA injection (P < 0.05). Accordingly, the average daily gain (ADG) of young squabs declined, and the mortality rate increased significantly (P < 0.05). Together, the results showed that RAPA reduced protein and amino acid levels in the crop milk of breeding pigeons and retarded young squab growth, suggesting a crucial role of TORC1 in crop milk synthesis in breeding pigeons.

Abstract
Objective: To compare the blood flow around the optic disc and related factors in patients with acute and chronic non-arteritic anterior ischemic optic neuropathy (NAION) and healthy volunteers with small disc cups under the same anatomical structure. Methods: This was a prospective case-control study. NAION patients with unilateral onset and healthy volunteers of the same phase were included in the study conducted at the Department of Ophthalmology of Peking Union Medical College Hospital between February 2017 and September 2018. Patients with a course of ≤ 3 months were categorized in the acute phase of NAION, and those with a course of >3 months were in the chronic phase of NAION. Healthy volunteers were in the control group. All subjects underwent the examination of best corrected visual acuity converted to logarithm of the minimum angle of resolution (LogMAR), measurement of non-contact intraocular pressure, slit lamp examination, small pupil fundus examination, and axial measurement. Optical coherence tomography was used to measure the thickness of retinal nerve fiber layers (RNFL) and retinal ganglion cell complex (GCC). Optical coherence tomography angiography was used to measure the vessel density around the optic disc. NAION patients underwent the visual field examination. Analysis of variance, non-parametric Mann-Whitney U test and Spearman coefficient was used for statistical analysis. Results: This study included 16 patients with acute phase of NAION, aged (57±9) years, 6 males and 10 females. There were 17 patients with chronic disease, aged (56±10) years, 7 males and 10 females. There were 15 healthy controls, aged (57±10) years old, 6 males and 9 females. There were no significant differences in age and gender between the groups (both P>0.05). The RNFL and the GCC in the NAION chronic phase group were significantly thinner than those in the acute phase group [(78±38) μm vs. (191±99) μm, (75±19) μm vs. (98±28) μm; t=4.389, 2.758; both P<0.05]. The cup/disc area ratio, cup/disc vertical diameter ratio and cup/disc horizontal diameter ratio in the chronic phase group were larger than those in the acute phase group [0.18 (0.11, 0.31) vs. 0.05 (0.01, 0.18), 0.45 (0.39, 0.56) vs. 0.22 (0.11, 0.41), 0.39 (0.28, 0.54) vs. 0.20 (0.07, 0.42)], and the difference was statistically significant (U=212.000, 208.000, 205.000; all P<0.05). Compared with the optic disc vessel density in the control group (53%±6%), there was a significant decrease in the acute phase group and the chronic phase group (45%±7%, 41%±8%; t=3.705, 4.940; both P<0.01). The blood vessel density in the nasal inferior of the chronic phase group was significantly lower than that in the acute phase group (36%±8% vs. 42%±7%, P=0.039), other sections didn't have significant difference (all P>0.05). There were tortuous capillaries in 8/16 of the acute phase cases, with a low blood flow density and visual field defect in relative positions. Correlation analysis showed that the whole density and peripapillary density in the NAION patients were negatively correlated with LogMAR, mean visual field defect, cup/disc area ratio, focal loss of volume of GCC and general loss of volume of GCC (r=-0.510, -0.733, -0.372, -0.532, -0.648; all P<0.01), but positively correlated with GCC and RNFL thickness (r=0.604, 0.508; both P<0.01). Conclusions: The optic disc vessel density in the acute phase and chronic phase of NAION is significantly reduced. The vessel density in the nasal area of the chronic phase is significantly reduced compared with the acute phase. The vessel density is correlated with visual acuity, visual field defect, disc indexes, thickness of RNFL and GCC. (Chin J Ophthalmol, 2019, 55: 677-686).

Abstract
Precision measurements by the Alpha Magnetic Spectrometer (AMS) on the International Space Station of ^{3}He and ^{4}He fluxes are presented. The measurements are based on 100 million ^{4}He nuclei in the rigidity range from 2.1 to 21 GV and 18 million ^{3}He from 1.9 to 15 GV collected from May 2011 to November 2017. We observed that the ^{3}He and ^{4}He fluxes exhibit nearly identical variations with time. The relative magnitude of the variations decreases with increasing rigidity. The rigidity dependence of the ^{3}He/^{4}He flux ratio is measured for the first time. Below 4 GV, the ^{3}He/^{4}He flux ratio was found to have a significant long-term time dependence. Above 4 GV, the ^{3}He/^{4}He flux ratio was found to be time independent, and its rigidity dependence is well described by a single power law ∝R^{Δ} with Δ=-0.294±0.004. Unexpectedly, this value is in agreement with the B/O and B/C spectral indices at high energies.

Abstract
Carrier transport in AlGaN-based deep ultraviolet (DUV) light emitting diodes (LEDs) with the wavelength of 273 nm has been investigated by introducing polarization modulated electron blocking layer (EBL) that adopts an Al composition and thickness graded multiple quantum barriers (MQB) structure. The experimental result shows that the maximum light output power and external quantum efficiency for the proposed structure at the current of 250 mA are 9.6 mW and 1.03% respectively, severally increasing by 405% and 249% compared to traditional one, meanwhile, the efficiency droop at 250 mA is also dramatically reduced from 42.2% to 16.6%. Further simulation analysis indicates that this graded MQB-EBL enhances the potential barrier height for electrons and meanwhile reduces that for holes, hence effectively suppresses the electron leakage, and at the same time significantly improves the hole injection efficiency. As a result, the whole performance of the LED with the proposed MQB-EBL is dramatically improved.

Abstract
Objective: To investigate the incidence and risk factors of extraintestinal manifestations (EIMs) in children with inflammatory bowel disease (IBD). Methods: The clinical data of 161 children with IBD was collected from the electronic medical records in the Department of Pediatrics, Ruijin Hospital, Shanghai Jiao Tong University, School of Medicine from January 2012 to December 2017. These patients were divided into Crohn's disease (CD) group and ulcerative colitis (UC) group, accounting for 82.0% (132 cases) and 18.0%(29 cases), respectively. The incidence of EIMs in each group was analyzed. The potential risk factors of EIMs including the IBD phenotype, gender, age, location of the CD lesion, disease activity of CD, and the presence of perianal lesion were analyzed with logistic regression model. Results: Eighty-eight patients (54.7%) had EIMs. The main EIMs were immune-mediated EIMs and growth retardation, accounting for 41.0% (66/161) and 24.2% (39/161), respectively. Aphthous ulcer (39/161, 23.0%) was the most common symptom among immune-mediated EIMs, followed by arthropathy (20/161, 12.4%) and skin lesions (19/161, 11.8%). Forty-three patients (26.7%) had EIMs before being diagnosed as IBD. Fifty-eight (65.9%) patients had only one EIM during the whole course of IBD. By logistic regression analysis, CD (OR=5.536, 95%CI:1.825-16.788) and perianal disease (OR=1.969, 95%CI:1.035-3.746) were the risk factors of immune-mediated EIMs. Meanwhile, CD (OR=11.319, 95%CI: 1.487-86.179), younger than six-year-old at diagnosis (OR=8.556, 95%CI: 3.109-23.545), moderate to severe activity of CD (OR=3.447, 95%CI: 1.196-9.934) and perianal disease (OR=3.361, 95%CI: 1.720-7.793) increased the risk of growth retardation. Conclusions: The children with IBD have a high incidence of EIMs, which were more common in CD than in UC. The risk factors of developing EIMs include CD, perianal diseases, younger than six-year-old at diagnosis and moderate to severe activity of CD.

Abstract
Objective: To investigate the association between plasma selenium exposure and the risk of impaired glucose regulation (IGR). Methods: A case-control study was conducted to select IGR patients who were admitted to the outpatient clinic of the Department of Endocrinology to perform oral glucose tolerance test(OGTT) at the Tongji Hospital affiliated to the Tongji Medical College from September 2004 to 2016 as a case group. Participants with normal glucose tolerance recruited from an unselected group of population undergoing routine health examinations in the same hospital were selected as a control group. The control group was matched according to the age (±5 years old) and sex of the case group. The inclusion criteria for subjects recruited were as follows: age ≥30 years, body mass index (BMI) <40 kg/m(2), no history of a diagnosis of IGR or type 2 diabetes, and no history of receiving pharmacological treatment for hyperlipidemia or hypertension. Patients with any clinically systemic disease such as neurological or endocrine disease, acute illness, chronic inflammatory disease or infectious disease were excluded from the study. A total of 1 957 subjects, 897 in the case group and 1 060 in the control group, were included. Questionnaires were used to collect information of all subjects, and peripheral venous blood was collected after fasting and OGTT, respectively. Plasma selenium, fasting blood glucose, blood lipid (total cholesterol, triglycerides, high density lipoprotein cholesterol, and low density lipoprotein cholesterol) and 2 h OGTT plasma glucose concentration were detected, respectively. The subjects were divided into low, medium and high concentration groups according to the tertiles of plasma selenium concentration in the control group. The multivariate unconditional logistic regression analysis was performed to analyze the association between plasma selenium exposure and IGR. Results: The age (mean±SD) of the case and control group was (53.71±11.38) and (53.95±12.17) years old. The plasma selenium concentration [M (P(25), P(75))] in the case group was 92.81(77.07, 107.05) μg/L, which was significantly higher than the control group [88.73 (77.13, 100.88) μg/L] (P<0.05). The results of multivariate unconditional logistic regression analysis showed that after adjusting for age, sex, BMI, family history of diabetes and hypertension, the risk of IGR was higher in the high-concentration group and the low-concentration group compared with the middle-concentration group, the values of OR (95%CI) were 1.22 (95%CI: 0.94-1.59) and 1.81 (95%CI: 1.42-2.30), respectively. Conclusion: The study suggested a U-shaped association between plasma selenium and IGR.

Abstract
With the extensive use of sentinel lymph node biopsy (SLNB), some breast cancer patients could avoid axillary lymph node dissection (ALND) and its complications. Neoadjuvant chemotherapy plays an important role in the multimodality therapies of breast cancer. After neoadjuvant chemotherapy, some patients with breast cancer were down-staged from positive axillary lymph node (cN+ ) to clinically negative (cN0). For these patients, the feasibility and safety of sentinel lymph node biopsy remains controversial. However, with the application of new technologies, SLNB is expected to become the main treatment for breast cancer patients with stage cN0 after neoadjuvant chemotherapy.

Abstract
Objective: To investigate the prevalence, demographic characteristics and social life function of mental disorders in the rural left behind elderly aged 60 years and older in Gansu. Methods: Between November 2017 and June 2018, a multi-stage stratified cluster sampling method was used to randomly select the rural left behind elderly aged 60 years and older in Gansu, and totally 6 000 elderly were enrolled. By using the extended general health questionnaire (GHQ-12) and the American Handbook for Diagnosis and Statistics of Mental Disorders (DSM-Ⅳ) Axis Ⅰ Disorders Formal Clinical Examination Patient Edition, all the included subjects were screened and diagnosed. Functional status was assessed by the Global Assessment Function scale (GAF). Statistical analysis of the prevalence of various mental illnesses, as well as the differences in the prevalence of different gender, marital status and age groups was performed. Results: Totally, 6 000 subjects completed the survey. The adjusted current prevalence of any mental disorder was 20.11% (95%CI 17.70%-22.85%). The six most prevalent specific disorders were major depressive disorder (9.20%), pain disorder (2.71%), mood disorder due to the body condition (2.08%), generalized anxiety disorder (1.99%), anxiety disorder not otherwise specified (1.15%) and dysthymic disorder (0.84%). The lifetime prevalence of mental disorders was 20.54% (95%CI 18.40%-23.39%). The overall current prevalence of mental disorders was higher in women (242.89‰) than in men (119.55‰), and the unmarried (248.37‰) was higher than those married (187.53‰). There was no significant difference in the prevalence of mental disorders among different age groups (P>0.05). The GAF score of mental disorders was 56±11, and 71.82% was moderate to severe functional impairment. Conclusions: The prevalence of mental disorders is high in rural left-behind population aged 60 years and over in Gansu Province. Major depression is a condition that deserves special attention.

Abstract
Objective: To investigate the consequences of the thickness of ganglion cell layer (GCL) and visual field defect of non-functional pituitary adenoma with chiasm compression. Methods: A case control study. The study included 40 (80 eyes) non-functional pituitary adenoma patients in Peking Union Medical College Hospital from March 2015 to February 2017. Twenty patients (no visual field defect group, 40 eyes) of them were detected to be chiasm compressed or touched by the adenoma with no visual field defect detected, and the other 20 patients (visual field defect group, 40 eyes) were the sex-and-age matched pituitary adenoma patients with bitemporal heminopsia. This study also included 20 (control group, 40 eyes) sex-and-age matched healthy controls. The para-papillary retinal nerve fiber layer (RNFL) thickness in 6 quadrants including nasal, temporal, nasal superior, temporal superior, nasal inferior and temporal inferior as well as the macular GCL thickness and ganglion cell-inner plexiform layer (GCIPL) thickness in 4 quadrants including nasal superior, nasal inferior, temporal superior and temporal inferior were measured. The non-parametric test was used to compare the RNFL, GCL and GCIPL thickness among the three groups. Results: The mean age among the three groups was (46±10) years and the difference among the three groups was not significant (P=0.88). The sex ratio of the three groups was 9∶11 (male∶female) and the difference among the three groups was not significant. The mean axial length among the three groups was (23.22±0.90) mm and the difference among the three groups was not significant (P=0.51). The thickness of para-papillary RNFL of temporal superior, temporal, nasal superior, nasal, nasal inferior quadrants and whole circumference was significantly thinner in the visual field defect group than the control group [(129.88±28.64) μm, (63.63±26.84) μm, (88.08±32.16) μm, (50.68±19.99) μm, (92.48±25.06) μm, and (85.00±20.65) μm vs. (141.10±18.95) μm, (79.12±16.78) μm, (113.68±21.28) μm, (69.67±14.23) μm, (117.80±31.32) μm, and (102.80±9.68) μm, t=2.26, 3.06, 4.14, 4.84, 4.25, 4.88, all P<0.05]. In the nasal quadrant, the para-papillary RNFL of the no visual field defect group was significantly thinner compared with the control group [(61.45±9.83) μm vs. (69.67±14.23) μm, t=2.97, P<0.05]. The total GCL thickness was (30.48±5.42) μm in the visual field defect group, (31.35±2.77) μm in the no visual field defect group, thinner than that in the control group [(33.32±2.92) μm, t=2.92, 3.62; both P<0.05]. The total GCIPL thickness showed no significant difference among the three groups (P=0.07). In the superior and inferior temporal quadrants, the GCL and GCIPL thickness showed no significant difference among the three groups (all P>0.05). In the superior and inferior nasal quadrants, the GCL thickness was (29.41±5.97) μm, and (28.47±5.13) μm in the visual field defect group, (31.15±3.27) μm and (30.61±2.96) μm in the no visual field defect group, and (34.23±3.16) μm and (32.97±2.78) μm in the control group. The GCL thickness in the nasal quadrant was thinner in the visual field defect group (t=4.45, 4.82)and the no visual field defect group(t=4.23, 3.63) than in the control group (all P<0.01). However, no significant difference in GCL thickness was detected between the visual field defect group and the no visual field defect group (both P>0.05). In the superior and inferior nasal quadrants, the GCIPL thickness was (54.06±10.50) μm and (51.77±9.18) μm in the visual field defect group, (58.03±4.00) μm and (56.23±5.37) μm in the no visual field defect group, and (62.26±7.11) μm and (59.39±6.64) μm in the control group. The GCIPL thickness was thinner in the nasal quadrant in the visual field defect group than in the control group (t=3.95, 4.20, both P<0.01). Only in the Superior nasal quadrant, the GCIPL was significantly thinner in the no visual field defect group than the control group (t=3.25, P<0.01). Conclusion: The optic GCL may get thinner in pituitary nonfunctional adenoma with chiasm compression patients without the RNFL layer thinning and visual field defect.

Abstract
Objective: To investigate the correlation between cervical lymph node skip metastasis with ultrasonographic characteristics of papillary thyroid micro- carcinoma (PTMC). Methods: We reviewed ultrasonographic features of 385 primary PTMC and cervical lymph node metastasis, confirmed by pathology in Tianjin Medical University Cancer Institute and Hospital, to evaluate the efficacy of ultrasonography in the diagnosis of cervical lymph node metastasis of PTMC patients. The relationship between ultrasonographic features of primary lesions and skip metastasis of cervical lymph nodes was analyzed by χ(2) test and multiple factor Cox regression. Results: Among the 385 cases of PTMC patients with cervical lymph node metastasis, 231 cases were central lymph node metastasis alone, 31 cases were lateral cervical lymph node metastasis alone, 123 cases were both central and lateral cervical lymph node metastasis. Among the 354 cases without skip metastasis of cervical lymph nodes, 48 cases were level Ⅱ, 92 cases were level Ⅲ, 83 cases were level Ⅳ, 9 cases were level Ⅴ, 354 cases were level Ⅵ. Among the 31 cases with skipping metastasis of cervical lymph nodes, 12 cases were level Ⅱ, 14 cases were level Ⅲ, 14 cases were level Ⅳ, 1 case was level Ⅴ. The sensitivity and specificity of preoperative ultrasonography in the diagnosis of central cervical lymph node metastasis were 46.3% and 66.7%, respectively, and those of lateral cervical lymph node were 91.0% and 87.8%, respectively. Univariate analysis showed that the abutment/perimeter, diameter and location of PTMC were significantly associated with skip metastasis (P<0.05), multivariate analysis showed that abutment/perimeter and location of PTMC were significantly associated with skip metastasis (P<0.05). Conclusions: The sensitivity and specificity of preoperative ultrasound diagnosis for lateral cervical lymph node metastasis of PTMC is higher than that of central metastasis. PTMC with abutment/perimeter ≥1/4 and upper portion location are prone to skip metastasis.

Abstract
Objective: To investigate the incidence of occult cervical lymph node metastasis and the common neck level of metastases in cN0 laryngocarcinoma, and the relationship between the clinicopathologic features of laryngocarcinoma and cervical lymph node metastasis. Methods: A total of 506 cases with cN0 laryngocarcinoma treated at the First Affiliated Hospital of Chongqing Medical University between March 2011 and March 2018 were enrolled, and their medical records and follow-up data were retrospectively analyzed. Of them, 211 cases of were glottic carcinoma in stage T1 without neck dissection and they were observed by clinical follow-up; other 295 cases, including glottic carcinoma, supraglottic carcinoma and hypopharyngeal carcinoma in stage T2-T4 were treated with surgical resection of the primary lesions and selective neck dissection. SPSS 22.0 software was used to analyze the data. Results: The total incidence of cervical lymph node metastasis was 10.87%(55/506), with a lower incidence in T1 stage glottic carcinoma(6/211,2.84%) than that in other cases(49/295,16.61%). The incidence of cervical lymph node metastasis in glottic carcinoma (29/426, 6.81%) was lower than those in supraglottic carcinoma (22/71,30.99%) and subglottic carcinoma (4/9) (χ(2)=35.810,P<0.01).The pN+ rates of glottic carcinoma at T1, T2, T3 were 2.84%(6/211), 5.31%(6/113), 16.05%(13/81), and 19.05%(4/21), respectively (χ(2)=18.572, P<0.01). The pN+ rates of supraglottic carcinoma at T2, T3 and T4 were 3/13, 32.50%(13/40) and 6/13, respectively (χ(2)=3.649,P>0.05). The incidence of cervical lymph node metastasis in poorly differentiated carcinoma (17/42, 40.48%) was higher than those in moderately differentiated carcinoma (26/205, 12.68%) and high differentiated carcinoma(12/246, 4.88%)(χ(2)=36.356, P<0.01). Moreover, 85 pN+ lymph nodes were obtained by selective neck dissection, respectively 43(50.59%) in level Ⅱa, 30(35.29%) in level Ⅲ, 1(1.18%) in level Ⅳ and 11(12.94%) in level Ⅵ. Conclusions: The occult cervical lymph node metastasis was frequently found in cN0 laryngocarcinoma. Selective neck dissection should be performed with surgery for the primary lesions in T3-T4 glottic laryngeal cancer, T2-T4 supraglottic laryngeal cancer and subglottic carcinoma, and the neck dissection for level Ⅱa and Ⅲ is appropriate. It is required to detect pre-laryngeal and pre-tracheal lymph nodes in patients with subglottic laryngeal carcinoma.

Abstract
Precision results on cosmic-ray electrons are presented in the energy range from 0.5 GeV to 1.4 TeV based on 28.1×10^{6} electrons collected by the Alpha Magnetic Spectrometer on the International Space Station. In the entire energy range the electron and positron spectra have distinctly different magnitudes and energy dependences. The electron flux exhibits a significant excess starting from 42.1_{-5.2}^{+5.4} GeV compared to the lower energy trends, but the nature of this excess is different from the positron flux excess above 25.2±1.8 GeV. Contrary to the positron flux, which has an exponential energy cutoff of 810_{-180}^{+310} GeV, at the 5σ level the electron flux does not have an energy cutoff below 1.9 TeV. In the entire energy range the electron flux is well described by the sum of two power law components. The different behavior of the cosmic-ray electrons and positrons measured by the Alpha Magnetic Spectrometer is clear evidence that most high energy electrons originate from different sources than high energy positrons.
