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
Purpose Whether the association between diabetic kidney disease (DKD) and diabetic retinopathy (DR) in patients with type 2 diabetes mellitus (T2DM) is leveraged by anemia remains unclear. This study is to evaluate the joint effect of DKD and anemia on DR. Methods Data were collected from electronic medical records of 1389 patients with T2DM in the Yiwu Central Hospital of Zhejiang Province from 2018 to 2019. Based on retinal examination findings, patients were classified as without diabetic retinopathy (non-DR), non-proliferative diabetic retinopathy (NPDR), and proliferative diabetic retinopathy (PDR). Odds ratio (OR) from multinomial logistic regression models adjusting for potential risk factors of DR were used to evaluate associations of DKD, renal function measures, and anemia with risk of NPDR and PDR. Path analysis was performed to help understand the association of DKD and hemoglobin (Hb) with DR. Results The study included 901 patients with non-DR, 367 patients with NPDR and 121 patients with PDR. Both high DKD risk and abnormal renal function measures were significantly associated with PDR. Anemia was associated with increased risk of NPDR (OR = 1.75, 95% confidence interval [CI] = 1.18–2.58) and PDR (OR = 3.71, 95% CI = 2.23–6.18). DKD severity and anemia had joint effect on NPDR (OR = 2.29, 95% CI = 1.32–3.96) and PDR (OR = 11.31, 95% CI = 5.95–21.51). These associations were supported by path analysis. Conclusions DKD severity, abnormal estimated glomerular filtration rate (eGFR), and urinary albumin/creatinine ratio (UACR) were associated with increased risk of DR in patients with T2DM, and anemia had joint effect on these associations. Improving Hb level may decrease the risk of DR in patients with T2DM.

Abstract
Transition-metal sulfides are key cathode materials for thermal batteries used in military applications. However, it is still a big challenge to prepare sulfides with good electronic conductivity and thermal stability. Herein, we rapidly synthesized a Co-doped NiS2 micro/nanostructure using a hydrothermal method. We found that the specific capacity of the Ni1-xCoxS2 micro/nanostructure increases with the amount of Co doping. Under a current density of 100 mA cm-2, the specific capacity of Ni0.5Co0.5S2 was about 1565.2 As g-1 (434.8 mAh g-1) with a cutoff voltage of 1.5 V. Owing to the small polarization impedance (5 mΩ), the pulse voltage reaches about 1.74 V under a pulse current of 2.5 A cm-2, 30 ms. Additionally, the discharge mechanism was proposed by analyzing the discharge product according to the anionic redox chemistry. Furthermore, a 3.9 kg full thermal battery is assembled based on the synthesized Ni0.5Co0.5S2 cathode materials. Notably, the full thermal battery discharges at a current density of 100 mA cm-2, with an operating time of about 4000 s, enabling a high specific energy density of around 142.5 Wh kg-1. In summary, this work presents an effective cathode material for thermal battery with high specific energy and long operating life.

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

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

Abstract
Objective: To identify the risk factors of non-sentinel lymph node (nSLN) metastasis in breast cancer patients with 1~2 positive axillary sentinel lymph node (SLN) and construct an accurate prediction model. Methods: Retrospective chart review was performed in 917 breast cancer patients who underwent surgery treatment between 2002 and 2017 and pathologically confirmed 1-2 positive SLNs. According to the date of surgery, patients were divided into training group (497 cases) and validation group (420 cases). A nomogram was built to predict nSLN metastasis and the accuracy of the model was validated. Results: Among the 917 patients, 251 (27.4%) had nSLN metastasis. Univariate analysis showed tumor grade, lymphovascular invasion (LVI), extra-capsular extension (ECE), the number of positive and negative SLN and macro-metastasis of SLN were associated with nSLN metastasis (all P<0.05). Multivariate Logistic regression analysis showed the numbers of positive SLN, negative SLN and macro-metastasis of SLN were independent predictors of nSLN metastasis (all P<0.05). A nomogram was constructed based on the 6 factors. The area under the receiver operating characteristic curve was 0.718 for the training group and 0.742 for the validation group. Conclusion: We have developed a nomogram that uses 6 risk factors commonly available to accurately estimate the likelihood of nSLN metastasis for individual patient, which might be helpful for radiation oncologists to make a decision on regional nodal irradiation.

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

Abstract
INTRODUCTION There is no effective treatment for geographic atrophy (GA). To help design future GA treatment trials, we conducted a meta-analysis for GA growth rate and its variability in natural history studies. METHODS Literatures were searched up to April 30, 2020. Data were extracted independently by 2 authors and analyzed using random-effects models. RESULTS The pooled mean GA growth rate was 1.66 mm2/year (SD = 1.27 mm2/year, I2 = 97.0%, p < 0.001) from 23 studies (3,078 patients) reported with growth rate in mm2/year and 0.33 mm/year (SD = 0.17 mm/year, I2 = 83.0%, p < 0.001) from 12 studies (1,808 patients) reported with growth rate in mm/year. Larger mean baseline GA area in mm2 was associated with larger mean growth rate in both mm2/year and mm/year (p < 0.001). The sample size at 85% power for detecting 15% reduction in growth rate in a 2-arm GA trial is 464 and 209 patients per arm, respectively, for using mm2/year and mm/year as the primary outcome. DISCUSSION/CONCLUSION GA natural history studies had a pooled mean (SD) GA growth rate of 1.66 (1.27) mm2/year or 0.33 (0.17) mm/year. Because GA growth rate using mm/year requires smaller sample size than using mm2/year, GA growth rate in mm/year is recommended as the primary outcome measure for future GA trials.

Abstract
Transpiration occurs through stomata. The alteration of stomatal apertures in response to drought stress is an important process associated with water use efficiency (WUE). Trehalose-6-phosphate phosphatase (TPP) family genes have been reported to participate in adjustment of stomatal aperture. However, there have been no reports of the trehalose metabolism pathway genes improving WUE, and the upstream signalling pathway modulating these genes is not clear. Here, we demonstrate that a member of the TPP gene family, AtTPPI, confers drought resistance and improves WUE by decreasing stomatal apertures and improving root architecture. The reduced expression of AtTPPI caused a drought-sensitive phenotype, while its overexpression significantly increased drought tolerance. Abscisic acid (ABA)-induced stomatal closure experiments confirmed that AtTPPI mutation increased the stomatal aperture compared with that of wild-type plants; in contrast, overexpression plants had smaller stomatal apertures than those of wild-type plants. Moreover, AtTPPI mutation also caused stunted primary root length and compromised auxin transport, while overexpression plants had longer primary root lengths. Yeast one-hybrid assays showed that ABA-responsive element-binding factor1 (ABF1), ABF2, and ABF4 directly regulated AtTPPI expression. In summary, the way in which AtTPPI responds to drought stress suggests that AtTPPI-mediated stomatal regulation is an important mechanism to cope with drought stress and improve WUE.

Abstract
Density functional theory was employed to investigate the (111), (200), (210), (211) and (220) surfaces of CoS2. The surface energies were calculated with a sulfur environment using first-principle-based thermodynamics. It is founded that surfaces with metal atoms at their outermost layer have higher energy. The stoichiometric (220) surface terminated by two layer of sulfur atoms is most stable under the sulfur-rich condition, while the non-stoichiometric (211) surface terminated by a layer of Co atoms has the lower energy under the sulfur-poor environment. The electric structure results show that the front valence electrons of (200) surface are active, indicating that there may be some active sites on this face. There is an energy gap between the stoichiometric (220) and (211), which has low Fermi energy, indicating that their electronic structures are dynamically stable. Spin-polarized bands are calculated on the stoichiometric surfaces, and these two (200) and (210) surfaces are predicted to be noticeably spin-polarized. The Bravais-Friedel-Donnay-Harker (BFDH) method is adopted to predict crystal growth habit. The results show that the most important crystal planes for the CoS2 crystal growth are (111) and (200) planes, and the macroscopic morphology of CoS2 crystal may be spherical, cubic, octahedral, prismatic or plate-shaped, which have been verified by experiments.

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

The NIHSS score before operation, 24 hours after operation and 1 week after operation, the recanalization of occluded vessels during operation, the complications and the recovery after 3 months (3 months mRS score) were analyzed. Results: Of the 42 patients, 38 patients were successfully recanalized, and the recanalization rate was 90.48%. Postoperative hemorrhage in 6 cases and vasospasm in 17 cases. At 90 days after operation, the mRS score was 0 in 13 cases, 1 in 11 cases, 2 in 6 cases, and 0 cases died. Conclusions: Mechanical thrombotomy is safe and feasible for patients with distal branch occlusion of middle cerebral artery (M2, M3). However, the risks and benefits of patients should be fully considered.

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

Abstract
BACKGROUND China has been undergoing dramatic economic development, accompanied by increased education load on the young children. This study is to investigate the prevalence, type, severity, and associated risk factors of astigmatism in school students in eastern China. METHOD In this cross-sectional school-based study, students underwent refraction using NIDEK non-cycloplegic autorefractor. Astigmatism was defined as cylinder 1.5 diopter (D) or greater, and high astigmatism was defined as cylinder 3.0 D or greaterMultivariate regression models were used to determine factors associated with astigmatism. RESULTS Among 4801 children (55% male) with mean age (±standard deviation) 12.3 (±3.8) years, 680 (14.2, 95% confidence interval (95% CI): 13.2-15.2%) had astigmatism (85% were with-the-rule) and 103 (2.2, 95% CI: 1.8-2.6%) had high astigmatism. The prevalence rate of astigmatism was 7-8% in grades 4 or below, 15-16% in grades 6-8, 20% in grade 9, and 20-25% in grade 10 or above. In multivariate analyses, higher grade and male gender were associated with higher prevalence of astigmatism (all p < 0.0001) and high astigmatism (p = 0.04 for grade, p = 0.001 for gender). When multivariate models were further adjusted by spherical equivalent, only gender remained statistically associated with astigmatism (odds ratio (OR) = 1.65, p < 0.0001) and high astigmatism (OR = 2.21, p = 0.0004), myopic and hyperopic refractive error were significantly associated with higher risk of astigmatism and high astigmatism (all p < 0.0001). CONCLUSION Astigmatism is common in Chinese school-age children and increases with grade. Majority of astigmatism is with-the-rule. Male gender and myopic or hyperopic refractive error are significantly associated with higher prevalence and severity of astigmatism.

Abstract
Despite the wide application of super-resolution (SR) microscopy in biological studies of cells, the technology is rarely used to monitor functional changes in live cells. By combining fast spinning disc-confocal structured illumination microscopy (SD-SIM) with loading of cytosolic fluorescent Ca2+ indicators, we have developed an SR method for visualization of regional Ca2+ dynamics and related cellular organelle morphology and dynamics, termed SR calcium lantern imaging. In COS-7 cells stimulated with ATP, we have identified various calcium macrodomains characterized by different types of Ca2+ release from endoplasmic reticulum (ER) stores. Finally, we demonstrated various roles of mitochondria in mediating calcium signals from different sources; while mitochondria can globally potentiate the Ca2+ entry associated with store release, mitochondria also locally control Ca2+ release from the neighboring ER stores and assist in their refilling processes.
