Abstract
Objective To explore the applied value of mismatch negative (MMN) in evaluation of severity of mental disorders due to traumatic brain injury. Methods Thirty-five patients(case group) that conform to the diagnostic criteria of organic (traumatic brain injury) mental disorder in ICD-10 Classification of Mental and Behavioural Disorders criteria were selected. Twenty-four healthy subjects (normal control group) that matched the case group in terms of gender, age composition ratio and educational level were selected. All subjects were evaluated by Activity of Daily Living Scale (ADL) and Social Disability Screening Schedule (SDSS) and then examined by Event-Related Potential (ERP). A statistical analysis of the data was made by SPSS 22.0 software. Results The 32 patients and 24 normal control subjects completed the study. The scores of ADL and SDSS were significantly higher in the case group than in the normal control group (P<0.05). The latency of Fz, FCz, Cz and Pz in the case group was significantly longer than that in the normal control group (P<0.05). In the case group, the latency of Fz, FCz, Cz and Pz was positively correlated with the scores of ADL and SDSS (P<0.05). The equation can be well fitted with the scores of ADL and SDSS. The latency and amplitude of Fz, FCz, Cz and Pz were used as concomitant variables and whether or not the subjects had mental disorders due to traumatic brain injury as dependent variables. Conclusion The latency of MMN can be used as an indicator in potential evaluation of the severity of mental disorders due to traumatic brain injury, which means that the longer the latency of MMN is, the more severe mental disorders due to traumatic brain injury may be. The combined application of ADL, SDSS and MMN can be an objective indicator in preliminary judgment of mental disorders due to traumatic brain injury.

Abstract
Objective: To investigate application and safety of pediatric interfacility-transport with extracorporeal membrane oxygenation (ECMO) in China. Methods: The data of 48 patients transported inter-hospital from February 2016 to May 2018 were collected from the following 4 centers: pediatric intensive care unit (PICU) of Bayi Children's Hospital Affiliated to the 7th Medical Center of PLA General Hospital, Pediatric Hospital of Fudan University, Henan Provincial People's Hospital and Children's Hospital of Zhejiang University School of Medicine. The data of patients' characteristics, ECMO mode and wean rate, and mortality were reviewed, which was further compared with the data of 57 compatible inner-hospital ECMO cases with t test, Rank sum test or chi-square test. Results: All the 48 interfacility-transports were accomplished by ambulance on land, with an average transfer distance of (435±422) km. The incidence of ECMO complications was 13% (6 case), without death. There were no significant differences in lactic acid, PaO(2) or SaO(2) before and after transport (4.0 (2.0, 7.5) vs. 3.0 (1.5, 6.0) mmol/L, Z=-1.579, P>0.05; 112(47, 405) vs. 166(122, 240) mmHg (1 mmHg=0.133 kPa), Z=-0.104, P>0.05; 0.97±0.02 vs. 0.96±0.03, t=1.570, P>0.05). Instead, PaCO(2) and pH were significantly different ((47±8) vs. (42±5) mmHg, t=2.687, P<0.05; 7.3±0.2 vs. 7.5±0.2, t=3.379, P<0.05). The total ECMO weaned rate was 73% (35/48) and the survival rate was 67% (32/48). No significant differences in demographic characteristics, ECMO mode or duration, transport distance or duration, or complications existed between the survival group and the death group (7/25 vs. 2/14, χ(2)=0.615, P>0.05; 4/28 vs. 2/14, χ(2)=0, P>0.05; (405±404) vs. (493±465) km, t=0.525, P>0.05; (5±4) vs. (5±5) h, t=0.388, P>0.05; 166 (128, 239) vs. 187(52, 405) h, Z=-0.104, P>0.05; 3/32 vs. 3/16, χ(2)=0.734, P>0.05). The lowest lactate value in survival group before ECMO transport was significantly lower than that in the death group ((5±5) vs. (8±6) mmol/L, t=2.151, P<0.05). There were neither significant differences in age, ECMO mode or support pattern (9/39 vs. 15/42, χ(2)=0.845, P>0.05; 6/42 vs. 7/50, χ(2)=0.001, P>0.05; 29/19 vs. 38/19, χ(2)=0.441, P>0.05), nor in ECMO weaned rate, survival rate or complications between interfacility-transport group and inner-hospital group (35/48 vs. 37/57, χ(2)=0.775, P>0.05; 32/48 vs. 35/57, χ(2)=0.313, P>0.05; 20/48 vs. 22/57, χ(2)=0.102, P>0.05). Conclusion: With appropriate transport equipment and mature teams who handle problems timely during the transport, critically ill children could be safely transported to the destination with ECMO.

Abstract
Objective: To investigate the current status of prevention and control of occupational hazards in a city in 2017, to understand the capability to prevent and control occupational hazards and the level of occupational health supervision and management, and to propose measures to urge employers to assume the main responsibility for the prevention and control of occupational diseases. Methods: An analysis of the main factors influencing the prevention and control of occupational hazards in the city was performed to screen out six semi-quantitative assessment indicators (including the training of the main responsible persons and occupational health management personnel in companies) and four qualitative assessment indicators (including the coverage of supervision and inspection of occupational hazards performed by the district safety supervision department) , which could be used to measure the prevention and control effects of regional occupational hazards. Each indicator was scored. The typical investigation method was used to do data review and on-site inspection of 170 companies, 17 district-level occupational health supervision departments, and 16 sub-district (township) occupational health supervision departments in the city from October to December, 2017. The prevention and control of occupational diseases in each district was scored, and the completion rate and completion situation of each indicator in the city were analyzed. Results: The mean score of prevention and control of occupational hazards in the city was 84.9. The scores of two districts were relatively high, being 88.9 and 88.7, respectively; the scores of 9 (52.9%) districts were higher than 85. The pass rate of training for the main responsible persons and occupational health management personnel in companies in the city was 95.9%, the pass rate of occupational health training for workers was 84.7%, the pass rate of occupational health examination for workers was 96.5%, the pass rate for the inspection of occupational hazardous factors in workplaces was 95.3%, the pass rate for notifying occupational hazards in workplaces is 95.9%, and the pass rate for applying the warning signs of occupational hazards in workplaces was 76.5%. Conclusion: The awareness of the importance of prevention and control of occupational hazards in all districts of the city has been increased, but the effectiveness of occupational health training for workers needs to be strengthened. The supply and demand of occupational health technical services are still not matched, and the ways and methods of occupational health supervision and inspection need to be improved.

Transplant Proc 2019; 51:768-773. [PMID: 30979462 DOI: 10.1016/j.transproceed.2019.01.062] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2018] [Revised: 10/25/2018] [Accepted: 01/17/2019] [Indexed: 10/27/2022]
Abstract
BACKGROUND AND AIM The present study aims to determine if homeostasis model assessment of insulin resistance (HOMA-IR) index, fasting plasma glucose (FPG), and plasma insulin (Ins) are able to predict development of new onset diabetes after transplant (NODAT) for kidney recipients. METHODS We performed a single-center retrospective study of 123 nondiabetic patients receiving a first renal transplant. The NODAT was diagnosed between 1 month and 1 year post transplant. Both univariate and multivariable analyses, including logistic regression analysis and Cox proportional hazards model, were applied to dissect potential pretransplant risk factors of NODAT. RESULTS A total of 26.8% (33/123) of recipients developed NODAT in the first year post transplant. The NODAT patients showed higher HOMA-IR index and increased levels of FPG and Ins than non-NODAT. Interestingly, we consistently revealed that both FPG (logistic: odds ratio [OR], 3.17 [1.41-6.45]; P = .01; Cox: OR, 2.75 [1.26-4.56]; P = .02) and HOMA-IR index (logistic: OR, 1.73 [1.21-2.87]; P = .02; Cox: OR, 1.72 [1.21-2.46]; P = .002) robustly predicted the development of NODAT. However, these analyses showed that neither plasma Ins nor hemoglobin A1c was associated with NODAT. CONCLUSION Our findings suggest that pretransplant HOMA-IR and FPG are independent predictors for the development of NODAT in Chinese nondiabetic patients receiving a first renal transplant.

Abstract
Boron (B) is essential for normal plant growth, including pollen tube growth. B deficiency influences various physiological and metabolic processes in plants. However, the underlying mechanism of B deficiency in pollen tube growth is not sufficiently understood. In the present research, the influence of B deficiency on apple (Malus domestica) pollen tube growth was studied and the possible regulatory mechanism evaluated. Apple pollen grains were cultured under different concentrations of B. Scanning ion-selective electrode technique, fluorescence labelling and Fourier-transform infrared (FTIR) analysis were used to detect calcium ion flux, cytosolic Ca2+ concentration ([Ca2+ ]cyt), actin filaments and cell wall components of pollen tubes. B deficiency inhibited apple pollen germination and induced retardation of tube growth. B deficiency increased extracellular Ca2+ influx and thus led to increased [Ca2+ ]cyt in the pollen tube tip. In addition, B deficiency modified actin filament arrangement at the pollen tube apex. B deficiency also altered the deposition of pollen tube wall components. Clear differences were not observed in the distribution patterns of cellulose and callose between control and B deficiency treated pollen tubes. However, B deficiency affected distribution patterns of pectin and arabinogalactan proteins (AGP). Clear ring-like signals of pectins and AGP on control pollen tubes varied according to B deficiency. B deficiency further decreased acid pectins, esterified pectins and AGP content at the tip of the pollen tube, which were supported by changes in chemical composition of the tube walls. B appears to have an active role in pollen tube growth by affecting [Ca2+ ]cyt, actin filament assembly and pectin and AGP deposition in the pollen tube. These findings provide valuable information that enhances our current understanding of the mechanism regulating pollen tube growth.

Abstract
Objective: To analyze the epidemiological characteristics of notifiable infectious diseases among Chinese students from 2011 to 2016 and to provide reference for the effective prevention and control programs on infectious disease among students. Methods: Both morbidity and mortality of notifiable infectious diseases among Chinese students aged 6-22 years from 2011 to 2016 were analyzed, with main characteristics of the disease described. Results: During 2011 to 2016, morbidities of Categories A, B and C infectious diseases among the Chinese students aged 6-22 years showed a decreasing trend, from 248.24/100 000 in 2012 to 158.57/100 000 in 2016. Mortality rates of Category A, B and C infectious diseases had also decreased from 0.12/100 000 in 2011 to 0.07/100 000 in 2016. The average morbidity of the top four diseases from Category A and B infectious diseases appeared as: tuberculosis (16.24/100 000), scarlet fever (9.39/100 000), hepatitis B (7.69/100 000) and bacillary and amebic dysentery (7.15/100 000). The average rates of mortality on the top four diseases appeared as: rabies (0.044 8/100 000), HIV/AIDS (0.027 7/100 000), tuberculosis (0.008 0/100 000) and Japanese encephalitis (0.005 9/100 000). The average rates of morbidity on the top four diseases appeared as: mumps (75.81/100 000), hand-foot-mouth disease (28.55/100 000), other infectious diarrhea (22.41/100 000) and influenza (15.67/100 000) in the Category C. Reported death cases were from hand-foot-mouth disease (11 cases), influenza (9 cases), mumps (1 case) and rubella (1 case). The prevalence rates varied among different student populations, with higher HIV/AIDS, hepatitis B and tuberculosis rates among college and senior high school students, while higher mumps, influenza and hand-foot-mouth disease rates among primary school and junior high school students. Conclusions: Both morbidity and mortality of notifiable infectious diseases among Chinese students aged 6-22 years had decreased significantly in 2011-2016. However, the major infectious diseases had become new challenges among students. HIV/AIDS had become a key infectious disease among college students and the relatively high prevalence of tuberculosis was seen in college and high school students.

Semi-dominant mutation in the cysteine-rich receptor-like kinase gene, ALS1, conducts constitutive defence response in rice. PLANT BIOLOGY (STUTTGART, GERMANY) 2019; 21:25-34.

Abstract
Plants have evolved a sophisticated two-branch defence system to prevent the growth and spread of pathogen infection. The novel Cys-rich repeat (CRR) containing receptor-like kinases, known as CRKs, were reported to mediate defence resistance in plants. For rice, there are only two reports of CRKs. A semi-dominant lesion mimic mutant als1 (apoptosis leaf and sheath 1) in rice was identified to demonstrate spontaneous lesions on the leaf blade and sheath. A map-based cloning strategy was used for fine mapping and cloning of ALS1, which was confirmed to be a typical CRK in rice. Functional studies of ALS1 were conducted, including phylogenetic analysis, expression analysis, subcellular location and blast resistance identification. Most pathogenesis-related (PR) genes and other defence-related genes were activated and up-regulated to a high degree. ALS1 was expressed mainly in the leaf blade and sheath, in which further study revealed that ALS1 was present in the vascular bundles. ALS1 was located in the cell membrane of rice protoplasts, and its mutation did not change its subcellular location. Jasmonic acid (JA) and salicylic acid (SA) accumulation were observed in als1, and enhanced blast resistance was also observed. The mutation of ALS1 caused a constitutively activated defence response in als1. The results of our study imply that ALS1 participates in a defence response resembling the common SA-, JA- and NH1-mediated defence responses in rice.

Abstract
AIMS To compare the efficacy of treatment with lamivudine (LAM) plus adefovir (ADV) or entecavir (ETV) monotherapy in LAM treatment failure patients with HBeAg negative chronic hepatitis B (CHB) patients during 48 weeks of therapy. PATIENTS AND METHODS Thirty patients with HBeAg negative CHB were enrolled in the study. The serum levels of HBV DNA, HBsAg/HBsAb, and ALT were assessed by enzyme-linked immunosorbent assay at 0, 12, 24, 36, and 48 weeks. RESULTS The rate of undetectable HBV DNA in the LAM+ADV group was 100%, which was higher than the ETV group at 48 weeks (73.33%, χ2 = 4.615, P = 0.032). Multivariate analysis using the Cox proportional hazards model showed that therapy with LAM+ADV or baseline levels of HBV DNA <107 copies/ml were independent predictive factors for undetectable HBV DNA rates in all patients (RR: 2.488, P = 0.042; RR: 0.201, P = 0.035). CONCLUSIONS During the 48 weeks of treatment in patients with HBeAg negative CHB, LAM plus ADV suppressed HBV replication more effectively than ETV monotherapy. In addition, no virologic breakthrough was detected in the LAM add-on ADV group. Additionally, therapy with LAM+ADV or baseline levels of HBV DNA <107copies/ml were independent predictive factors for undetectable HBV DNA rates in patients.

Abstract
BACKGROUND Dexmedetomidine attenuates renal ischaemia and reperfusion (I/R) injury, but its mechanism of action is unclear. As sirtuin 3 (SIRT3) activation can alleviate acute kidney injury, we investigated whether dexmedetomidine acts through SIRT3 to reduce renal I/R injury. METHODS The potential involvement of SIRT3 in dexmedetomidine attenuation of renal I/R injury was tested in HK2 cells subjected to hypoxia/reoxygenation and C57BL/6J mice subjected to renal I/R. A short interfering RNA targeting SIRT3 was used in some experiments to examine the potential role of SIRT3. Cell death and mitochondrial membrane potential (Δψm) were analysed in cultured cells. Mitochondrial damage in mice was assessed using electron microscopy and markers for renal function. Expression of cyclophilin D, cytochrome c, and SIRT3, and the level of cyclophilin D acetylation were determined. RESULTS Hypoxia/reoxygenation of HK2 cells increased cell death, cytochrome C expression, and cyclophilin D acetylation, and decreased Δψm and SIRT3 expression (P<0.05). Dexmedetomidine attenuated these changes. The dexmedetomidine effects were enhanced by SIRT3 overexpression and eliminated by SIRT3 knockdown. I/R in mice damaged renal function, and increased histological lesions, mitochondrial damage, cytochrome c expression, and cyclophilin D acetylation, while SIRT3 activity was decreased by 51% (P<0.05). Dexmedetomidine inhibited these changes in mice expressing normal levels of SIRT3, but not in SIRT3-knockdown mice. CONCLUSIONS Dexmedetomidine appears to act, at least in part, by up-regulating SIRT3 to inhibit mitochondrial damage and cell apoptosis and thereby protect against renal I/R injury.

Abstract
BACKGROUND AND AIMS Several studies have reported increased cardiovascular risks in normal weight obesity (NWO) populations. We aimed to investigate the prevalence of NWO and its relationships with cardiometabolic risks in Chinese patients. METHODS AND RESULTS The data were from the 2007-2008 China National Diabetes and Metabolic Disorders Study. The body fat (BF) was measured using the biological impedance method. NWO was defined as a normal BMI (18.5-23.9 kg/m2) but with excess BF% (BF% ≥ 24% for men and ≥33% for women). 23,748 people (9633 males and 14,115 females) were enrolled and the prevalence of NWO was 9.5% for men, 6.06% for women. The prevalence risks of diabetes (odds ratio [OR]1.519, 95% confidence interval [CI] 1.262-1.828), Framingham risk score (FRS) ≥10% (OR 1.973, 95% CI 1.596-2.439), hypertension (OR 1.525, 95% CI 1.333-1.745), and metabolic syndrome Mets (OR 2.175, 95% CI 1.920-2.463) significantly increased in the NWO group compared with the normal group. Subgroup analyses showed that, after ruling out participants with abnormal waist circumference, the male group had similar findings to the overall population; but in the female group, the prevalence risks of FRS ≥10%, hypertension, and Mets increased, although the risk of diabetes did not. CONCLUSION NWO is in a relatively high prevalence in Chinese population, and the prevalence of NWO is higher in Chinese men compared to Chinese women. Cardiometabolic risks significantly increase in an NWO population, and such risks persist after excluding the effect of abdominal obesity.

Abstract
Plant pathology must address a number of challenges, most of which are characterized by complexity. Network analysis offers useful tools for addressing complex systems and an opportunity for synthesis within plant pathology and between it and relevant disciplines such as in the social sciences. We discuss applications of network analysis, which ultimately may be integrated together into more synthetic analyses of how to optimize plant disease management systems. The analysis of microbiome networks and tripartite phytobiome networks of host-vector-pathogen interactions offers promise for identifying biocontrol strategies and anticipating disease emergence. Linking epidemic network analysis with social network analysis will support strategies for sustainable agricultural development and for scaling up solutions for disease management. Statistical tools for evaluating networks, such as Bayesian network analysis and exponential random graph models, have been underused in plant pathology and are promising for informing strategies. We conclude with research priorities for network analysis applications in plant pathology.

Abstract
Objective: To explore the clinical application value of peripheral blood diagnostic report. Methods: 557 peripheral blood diagnostic reports were collected from Peking University First Hospital, YANDA LU DAOPEI Hospital and Beijing United Family Hospital. The results were analyzed and summarized according to different blood cell morphology character for the first time and review cases, respectively. Results: Two hundred and one samples from first time patients were found abnormal complete blood count or leukocyte differential count, they were summarized as anemia, anemia accompanied with leukopenia or thrombopenia, abnormal white blood cell count or leukocyte differential count and abnormal platelet count. Each condition was further distinguished on the basis of different morphology character. Initial diagnosis or further examination could be proposed if abnormal morphology was specific or typical, when blood cell morphology was atypical or normal, the morphology was described objectively. 22 review cases included many benign and malignant disorders such as acute leukemia, chronic leukemia, myelodysplastic syndrome, multiple myeloma, infectious mononucleosis and so on. Suggestion of therapeutic effect, progression of diseases or further examination could be present according to complete blood cell count and morphology character. Conclusion: Peripheral blood diagnostic report can provide more comprehensive and accurate information for clinic, and propose important advisory opinions for primary diagnosis, differential diagnosis, treatment monitoring and progression assessment.

Abstract
Absolute phase retrieval is essential for height measurement in digital fringe projection. However, projections of additional structured patterns that are normally required for phase unwrapping increase the measurement complexity. In this paper, we propose two reference-plane-based pixel-by-pixel absolute phase retrieval techniques with as few projections as possible, suitable for different object depth ranges. The wrapped phase on the object is absolutely unwrapped by referring just to the absolute phase map on the reference plane. Single-frequency absolute phase retrieval with one-reference-plane-based calibration is first proposed for objects within a height limit that equals a calibrated system constant. To extend the measurement depth range, dual-frequency absolute phase retrieval with two parallel reference planes is further proposed. The additional low frequency is used to choose the unwrapping reference from the two reference plane phases for unwrapping the high-frequency phase. Moreover, the proposed techniques are capable of high-frequency absolute phase unwrapping for objects with step-height surface discontinuities. Experiments have been conducted to demonstrate the efficiency of the proposed two techniques.

Abstract
WHAT IS KNOWN AND OBJECTIVE Uninterrupted warfarin during cryoballoon ablation (CB-A) of atrial fibrillation (AF) has been widely accepted. However, to our knowledge, no previous studies exist investigating the optimal intensity of anticoagulation with warfarin for CB-A. This study aimed to evaluate the efficacy and safety of uninterrupted low-intensity warfarin for CB-A of AF in the elderly. METHODS Paroxysmal AF patients (age ≥ 70 years) who underwent CB-A were enrolled prospectively. The participants were stratified into 2 groups based on international normalized ratio (INR) before ablation (INR in group A: 1.5 to 2.0; INR in group B: 2.0-2.5). Primary endpoints included periprocedural thromboembolic complications and major bleeding. Secondary endpoints were new asymptomatic cerebral emboli (ACE) and minor bleeding. RESULTS AND DISCUSSION A total of 144 patients were enrolled (group A: 65; group B: 79). In group A, the use of concomitant antiplatelet drugs was more common. Also, the mean HAS-BLED score was significantly higher (2.4 ± 0.8 vs 2.0 ± 0.6, P < .01) and the mean activated clotting time (ACT) during the procedure was significantly lower (302 ± 14 s vs 311 ± 11 s, P < .01). Other clinical characteristics were balanced between the 2 groups. No thromboembolic complications and major bleeding occurred in either group. The incidence of periprocedural ACE was comparable between the 2 groups (9.2% vs 6.3%, P = .74). The incidence of minor bleeding in group A and group B was 4.6% and 11.4%, respectively (P = .14). WHAT IS NEW AND CONCLUSION Compared with standard-intensity warfarin, uninterrupted low-intensity warfarin might not increase the incidence of thromboembolic complications and might be associated with less bleeding risk during the perioperative period of cryoballoon ablation in the elderly. Large trials are needed to confirm these results.

Abstract
Abstract
Rapamycin, a well-studied mTOR inhibitor, has been demonstrated to inhibit mammary carcinogenesis at multiple stages, including initiation, invasion, and metastasis, in preclinical animal models. Nevertheless, the cancer preventative potential and underlying mechanisms remain unclear, especially in individual breast cancer subtypes like ErbB2/Her2-positive breast cancers. ErbB2 amplification/overexpression is a particular clinical concern because it occurs in approximately one-third of human breast cancers and is associated with poor prognosis. Therefore, we used MMTV-ErbB2 transgenic mice as our model system to test the efficacy of rapamycin in the prevention of ErbB2-mediated mammary tumor development. Our initial data provided proof of concept regarding the anti-cancer effects of rapamycin in vivo. Indeed, rapamycin (1.5 mg/kg/day for 12 days) significantly reduced the volume and weight of syngeneic 78617 cell-derived mammary tumors in MMTV-ErbB2 mice, despite observed decreases in CD4+ and CD8+ immune cells. Since advanced mammary gland development can serve as an indicator of breast cancer risk, we investigated the effects of rapamycin on mammary gland development in MMTV-ErbB2 mice that were treated with low-dose rapamycin (1 mg/kg/day) between weeks 10 and 20 of age. As such, rapamycin significantly attenuated mammary morphogenesis at 20 weeks of age, as indicated by decreased branching density, ductal elongation, and proliferative index of the premalignant mammary glands. Flow cytometric analysis of isolated primary mammary epithelial cells (MECs) was performed using CD24 and CD49f markers to identify MEC populations. We found that rapamycin has a significant impact on MEC stemness based on changes in luminal (CD24highCD49flow), mammary stem cell (MaSC)-enriched (CD24highCD49fhigh), and myoepithelial/basal (CD24low/highCD49fhigh) MEC populations. We also used CD61 and CD49f markers to identify a population enriched with luminal progenitor cells (CD61highCD49fhigh) that was selectively inhibited by rapamycin. Consistent with our flow cytometric analyses, rapamycin inhibited the luminal progenitor cell-enriched population, self-renewal, and anchorage-independent cell growth of primary MECs, as demonstrated by colony-forming cell, mammosphere, and 3D culture assays, respectively. These functional stem cell assays further corroborate that rapamycin suppresses the stemness of primary MECs. Molecular analysis of MECs demonstrated that rapamycin inhibited mTOR signaling, as expected. Importantly, rapamycin also significantly suppressed the receptor tyrosine kinase/ErbB2, estrogen receptor, Wnt/β-catenin, and TGFβ/Smad3 signaling pathways prior to malignant transformation. Collectively, our study provides evidence that rapamycin has potential cancer preventative effects in the mammary glands of MMTV-ErbB2 mice during the premalignant risk window. These rapamycin-induced anti-cancer effects ultimately highlight the promising clinical significance of rapamycin for the prevention and treatment of human ErbB2-overexpressing breast cancers.

Abstract
Objective: To study the epidemiological characteristics of an outbreak caused by norovirus infection in a school in Haidian district, Beijing. Methods: Basic information of the school and data related to patients in the fields survey were collected and analyzed descriptively. Laboratory tests were performed to test the stool and anal swab specimens of both patients and cooks as well as the environmental specimens. Risk factors related to the incidence were analyzed through a case-control study. Results: A total number of 119 patients were identified in the school. Clinical symptoms were mild, mainly involving vomiting (94.1%, 112/119), abdominal pain (46.2%, 55/119), but no need of hospitalization. The average age of the student patients was 6.38, with minimum and maximum between 5 and 11. Patients were found in 22 classes, but mainly in grade 1 and class 7 where 35 patients were found (30.17%). A total of 134 specimens of rectal swabs and stool were collected, with 7 positive for norovirus and 6 for sappovirus. Salmonella, Shigella, lapactic Escherichia coli and Vibrio parahaemolyticus were not found in on dinner sets, residual foods, bottled water or in drinking fountains. Index on water hygiene was unsatisfactory in classrooms or dormitories where more cases were found. Accommodation, north-facing-classrooms, abnormal water hygiene indexes were found related to the occurance of the disease (P<0.05). Conclusions: The outbreak was identified a gastroenteritis infection, caused by norovirus with symptoms as vomiting and abdominal pain. This event reached the reporting standards of public health emergencies-level Ⅳ. Discovery and isolation of the first case was not timely while transmission of the disease might be water-borne. Surveillance programs on symptoms, disinfection of vomit and stool in places like nurseries and schools should be strengthened to prevent the norovirus outbreak.

Abstract
The optical power emitting from the cavity facet of blue InGaN-based laser diodes (LDs) is measured to investigate the efficiency droop. The efficiency droop behavior of blue InGaN-based LDs near the threshold is confirmed in our experiments. From measurements of optical power at different wavelengths, it is analyzed that the droop behavior of LDs can be ascribed to the efficiency reduction of longer wavelengths. The efficiency of longer wavelengths is subject to the carrier occupation process in quantum levels. In addition, it is found that the droop behavior may be largely affected by the relatively large threshold current of InGaN-based LDs and the screening effect of polarization, and it can be suppressed by stimulated emission.

Abstract
Bone desensitization after mechanical loading is essential for bone to adapt to its mechanical environment. However, the desensitization mechanism is unknown. Previous studies suggest that G protein-coupled receptors (GPCRs), including P2Y and parathyroid hormone receptors, play important roles in osteoblast mechanobiology. Thus, for the present research, we examined the role of G protein-coupled receptor kinase 2 (GRK2) in osteoblast desensitization after exposure to mechanical stimulation. We first showed the existence of osteoblast desensitization after mechanical stimulation based on cytosol Ca2+ and phosphorylated ERK1/2 activities, detected using a fluorescent Ca2+-sensitive dye and western blotting, respectively. We then demonstrated that GRK2 overexpression in MC3T3-E1 cells inhibits flow-induced ERK1/2 phosphorylation, while siRNA knockdown of GRK2 enhances ERK1/2 phosphorylation. Additionally, we found that GRK2 overexpression in MC3T3-E1 cells inhibits cyclooxygenase-2 mRNA expression in the short term and alkaline phosphatase activity in the long term. More importantly, we discovered that GRK2 translocated to the cell membrane shortly after flow stimulation - a step necessary for GPCR desensitization. Previously, we have demonstrated that P2Y2 purinergic receptors, one type of GPCRs, are involved in various flow-induced osteoblastic responses. In this research, we also showed that GRK2 overexpression does not affect ATP release. Accordingly, GRK2 is able to inhibit flow-induced osteoblast responses possibly through desensitizing P2Y2 receptors.

Abstract
BACKGROUND AND PURPOSE To determine whether iron deposition in deep brain nuclei assessed using high-pass filtered phase imaging plays a role in motor disease severity in Parkinson's disease (PD). METHODS Seventy patients with mild to moderate PD and 20 age- and gender-matched healthy volunteers (HVs) underwent susceptibility-weighted imaging on a 3 T magnetic resonance imaging scanner. Phase shifts (radians) in deep brain nuclei were derived from high-pass filtered phase images and compared between groups. Analysis of clinical laterality and correlations with motor severity (Unified Parkinson's Disease Rating Scale, Part III, UPDRS-III) were performed. Phase shifts (in radians) were compared between HVs and three PD subgroups divided according to UPDRS-III scores using analysis of covariance, adjusting for age and regional area. RESULTS Parkinson's disease patients had significantly (P < 0.001) higher radians than HVs bilaterally in the putamen, globus pallidus and substantia nigra (SN). The SN contralateral to the most affected side showed higher radians (P < 0.001) compared to the less affected side. SN radians positively correlated with UPDRS-III and bradykinesia-rigidity subscores, but not with tremor subscores. ancova followed by post hoc Bonferroni-adjusted pairwise comparisons revealed that SN radians were significantly greater in the PD subgroup with higher UPDRS-III scores compared to both lowest UPDRS-III PD and HV groups (P < 0.001). CONCLUSIONS Increased nigral iron accumulation in PD appears to be stratified according to disease motor severity and correlates with symptoms related to dopaminergic neurodegeneration. This semi-quantitative in vivo iron assessment could prove useful for objectively monitoring PD progression, especially in clinical trials concerning iron chelation therapies.
