Objective To investigate the relationships of nuclear factor кB (NF-кB) activation with protein kinase B (Akt) and glycogen synthase kinase 3β (GSK-3β) during amyloid-β (Aβ) (25-35) -induced apoptosis in pheochromocytoma cells (PC12 cells) of rats. Methods Apoptosis in PC12 cells was induced by A(25-35). The activities of Akt, GSK-3β and NF-кB were analyzed in this process. The Akt and GSK-3β pathways were blocked by their specific inhibitors, respectively, and the relationships of Akt and, GSK-3β with NF-кB during Aβ(25-35)-induced apoptosis in PC12 cells were determined. Results Aβ(25-35) induced apoptosis was in a dose-dependent manner. With 0, 5, 10, 20 μmol/L and 40 μmol/L Aβ(25-35) treaing for 48 h, the apoptosis rates of PC12 cells were (3. 01 ± 0.03)%, (3.08 ±0.03)%, (25.32 ± 0.76)%, ( 42.88 ± 0.60 )% and ( 60.85 ± 2.39 )% , respectively. Compared to control, both Akt and GSK-3β were suppressed during apoptosis, at meantime NF-кB was activated. The inhibited Akt activity by wortmannin leaded to decreased NF-кB activatity and increased GSK-3β activatity. Suppression of GSK-3β with its specific inhibitor LiCl caused the decreased activation of NF-кB too, but it had no significant influence on Akt activity. Conclusions These results suggest that both Akt and GSK-3β are upstream regulators of NF-кB. They co-regulate the activation of NF-кB during Aβ(25-35)-induced apoptosis in PC12 cells. This study contributes to the theoretical base for the pathogenesis of Alzheimer disease (AD) , and provides a new idea to AD prevention and therapy.

Objective:
This study aims to investigate the epidemiological distribution of HFMD and quantify the association of temperature with the incidence of children’s HFMD in Nanjing, China.
Methods:
Daily counts of HFMD in children under 5 years and daily meteorological variables during 2011-2016 were obtained. Descriptive statistics were used to describe the epidemiological characteristics and distributed lag non linear model (DLNM) was used to assess the associations of temperature on HFMD cases.
Results:
A total of 104 977 HFMD cases aged 0-5 years were reported in Nanjing during the study period and the male to female sex ratio was 1.49∶1. The average annual incidence was 213.5 per 100 000. A bimodal seasonal pattern was observed and the south and west were found to be the high incidence areas in the city. Of these laboratory confirmed enteroviruses positive cases, 32.5% cases were positive for EV-A71 infections, 29.1% cases were positive for CV-A16 infections and 38.4% cases were positive of other enteroviruses infections. The temperature HFMD relationships were non linear and showed obvious lag effects. The cumulative relative risk presented as an approximately inverted U shape over 14 days and peaked at 25.7 ℃ with value of 2.71(95%CI=1.93-3.81). Subgroup analyses revealed that males and children aged <1 year were more vulnerable to temperature variations.
Conclusion
Epidemiological characteristics of HFMD among children aged 0-5 years old in Nanjing presented temporal and regional distribution. The temperature has significant impact on children’s HFMD occurrence.

Objective:To evaluate the diagnostic performance of the prostate imaging reporting and data system version 2.1 (PI-RADS v2.1) based on multiparametric MRI (mpMRI) in the detection of clinically significant prostate cancer (csPCa).Methods:A total of 561 patients who underwent prostate mpMRI in the First Affiliated Hospital of Guangxi Medical University from June 2015 to December 2020 due to elevated prostate specific antigen were collected ambispectively. The patients were divided into csPCa group (276 cases) and non-csPCa group (285 cases) according to pathological findings. Prostate were scored according to the PI-RADS v2.1 scoring standard by a junior and a senior radiologist. The prostate volume was measured and the prostate specific antigen density (PSAD) was calculated. The diffusion-weighted imaging and dynamic contrast-enhanced MRI images were processed to measure the quantitative parameters of the index lesion, including apparent diffusion coefficient (ADC), volume transfer constant (K trans) and rate constant (K ep) values. The Mann-Whitney U test was used to compare the difference in parameters between the two groups. The predictors of csPCa were screened by logistic regression analysis. Predictive model of multi-parameter was established. The receiver operator characteristic curves were used to evaluate the efficacy of PI-RADS v2.1 and the model in diagnosing csPCa, and the comparisons of area under the curve (AUC) were conducted by DeLong test. Results:Compared with non-csPCa group, the patients in csPCa group had higher PI-RADS score of senior physician, PSAD, K trans and K ep value, lower ADC value ( Z=-16.69, -12.49, -3.43, -4.67, 13.91, all P<0.001). The PI-RADS scores of senior physician (OR=3.064, 95%CI 2.428-3.866, P<0.001), PSAD (OR=1.554, 95%CI 1.170-2.064, P=0.002) and ADC value (OR=0.095, 95%CI 0.032-0.288, P<0.001) were the predictors of csPCa. The AUC of junior, senior physician PI-RADS and combined prediction model were 0.861 (95%CI 0.830-0.892), 0.895 (95%CI 0.868-0.922) and 0.923 (95%CI 0.898-0.944). The pairwise difference was statistically significant (the PI-RADS score between the junior and senior physicians Z=3.24, P=0.001, the difference between the PI-RADS score of junior physician and prediction model Z=5.54, P<0.001, the difference between the PI-RADS score of senior physician and prediction model Z=4.20, P<0.001). Conclusion:Based on mpMRI, the application of PI-RADS v2.1 by junior and senior radiologists has the high diagnostic efficacy for csPCa, and the multi-parameter model has the best diagnostic efficacy for csPCa.

This paper summarized the clinical experience of professor XUAN Guowei in treating non-specific vulvitis from spleen. He believes that the core pathological mechanism of this condition lies in spleen deficiency and dampness accumulation; in the acute phase, spleen deficiency is taken as the root cause and damp-heat toxins accumulated in the vulva as the key; in the chronic phase, spleen deficiency and dampness accumulation is the main pathogenesis, accompanied by kidney deficiency. In clinical practice, the basic method of fortifying spleen and eliminating dampness is used, and self-made Jianpi Shenshi Formula (健脾渗湿方) is recommended as the basic prescription. During the acute phase, the medicinals of clearing heat and resolving toxins are supplemented, while during the chronic phase, medicinals aims at fortifying the spleen and consolidating the kidneys, boosting qi and nourishing yin are added. Simultaneously, there is an emphasis on integrated treatment combining internal and external treatment, and both Chinese and western medicine, and he highlights the importance of daily prevention and care for patients. Additionally, external used Xiaoyan Zhiyang Cream (消炎止痒霜) is created.

OBJECTIVE: To explore the influence of work pressure and psychological capital on job burnout of college teachers. METHODS: A total of 287 teachers from 7 universities in Nanjing City were selected as the research subjects using the convenient sampling method. The Maslach Burnout Inventory, Job Stress Scale for University Teachers and Psychological Capital Questionnaire were used to investigate their job burnout, job stress and psychological capital. RESULTS: The total scores of job burnout and job stress were(42.9±12.5) and(48.5±12.4) respectively, and the occurrence of job burnout was 64.1%. The total scores of psychological capital was(106.7±14.7), and the scores of the four dimensions including self-efficacy, hope, resilience and optimism were(27.6±4.6),(26.7±4.8),(27.0±4.2) and(25.4±3.8) respectively. The total score of job stress was positively correlated with the total score of job burnout [correlation coefficient(r)=0.41, P<0.01]. The total score of psychological capital, self-efficacy, hope, resilience and optimism were negatively correlated with the total score of job burnout(r values were-0.42,-0.28,-0.36,-0.36 and-0.42, respectively, P<0.01). The results of multiple linear regression analysis showed that after adjusting the influence of confounding factors and excluding other confounding factors, the higher the job stress, the higher the job burnout level(P<0.01), the higher the psychological capital optimism dimension score, the lower the job burnout level(P<0.01). CONCLUSION: The job stress and psychological capital of college teachers can independently affect their job burnout level, with a dose-effect relationship.
