ABSTRACT
Viruses are powerful tools for the study of modern neurosciences. Most of the research on the connection and function of neurons were done by using recombinant viruses, among which neurotropic herpesvirus is one of the most important tools. With the continuous development of genetic engineering and molecular biology techniques, several recombinant neurophilic herpesviruses have been engineered into different viral tools for neuroscience research. This review describes and discusses several common and widely used neurophilic herpesviruses as nerve conduction tracers, viral vectors for neurological diseases, and lytic viruses for neuro-oncology applications, which provides a reference for further exploring the function of neurophilic herpesviruses.

ABSTRACT
Objective:To investigate the incidence of social isolationin community elderly patients with knee osteoarthritis and analyze its influencing factors.Methods:From January to April 2021, 240 community elderly with knee osteoarthritis in three community health service centers in Taiyuan (Yingbin community, Dawang community and Pingyang second community) were selected as research objects by convenient sampling method. They were investigated by general data questionnaire, Lubben Social Network Scale-6(Lubben-6), Geriatric Depression Scale-15, Perceived Social Support Scale, Numerical Rating Scale. Single factor analysis and binary Logistic regression analysis were used to explore the influencing factors of social isolation in elderly patients with knee osteoarthritis.Results:The prevalence of social isolation among community elderly patients with knee osteoarthritis was 43.33% (104/240) . The results of binary logistic regression analysis showed that age ( OR = 2.228, 95% CI 1.436-3.457), complicated diseases ( OR = 1.733, 95% CI 1.028-2.919), exercise ( OR = 0.560, 95% CI 0.360-0.869), depression ( OR = 3.603, 95% CI 1.768-7.339), comprehension of social support ( OR = 0.424, 95% CI 0.253-0.710) and pain ( OR = 1.792, 95% CI 1.147-2.799) were the influencing factors of social isolation in elderly patients with knee osteoarthritis ( P<0.05). Conclusions:The degree of social isolation in community elderly patients with knee osteoarthritis is relatively high, and is affected by many factors. Community medical staff should formulate targeted nursing intervention plans based on their influencing factors to reduce the occurrence of social isolation.
ABSTRACT
Objective:To investigate the sedentary behavior of the elderly in Taiyuan nursing homes and analyze its influencing factors, so as to provide theoretical basis for the construction of targeted intervention programs for sedentary behavior.Methods:A total of 215 elderly people in 6 nursing homes in Taiyuan from October 2019 to January 2020 were investigated by general data questionnaire and sedentary behavior questionnaire. Descriptive analysis, single factor analysis and multiple linear stepwise regression analysis were used to explore the influencing factors of sedentary behavior.Results:The sedentary time of the elderly in Taiyuan nursing homes was (8.85±2.81) h/d, and 83% (174/209) of the elderly had a sedentary time≥6 h/d. Gender, age, type of disease, type of residence, sedentary hobby and environmental safety in homes were the important factors influencing sedentary behavior of the elderly in nursing homes( P<0.05). Conclusions:The sedentary behavior of the elderly in nursing homes is not optimistic. Targeted intervention measures should be taken to improve the sedentary behavior of the elderly and promote the healthy aging of the elderly in nursing homes.
ABSTRACT
After a long-term co-evolution, alphaherpesviruses have established mutual adaptability with their hosts. Some alphaherpesviruses have typical neurotropic characteristics, which have received extensive attention and in-depth research. Neurotropic alphaherpesviruses can break through the host barrier to infect neurons and multiply in large numbers in the neuron cell body to complete further proliferation or establish latent infection in the cell body. Either in the process of infecting neurons or further spreading, alphaherpesviruses will undergo transmission along axons or dendrites, so this process is an integral part of the life cycle of the viruses, and is also a key factor for the viruses to spread in nervous system. Therefore, studies on transportation of alphaherpesviruses in neurons will provide new insights of the viruses and promote the development of corresponding vaccines or targeted therapeutic pharmaceuticals. In addition, the neurotropism of alphaherpesviruses is conducive to the analysis of nerve circuits. Herein, the mechanisms of alphaherpesvirus transport in axons were reviewed, and the research direction and application of the transport of alphaherpesviruses in axons were put forward, which can provide reference for the prevention and control of alphaherpesviral infections.

Objective To study the expressions of transmembrane protease serine 2-E26 transformation specific (TMPRSS2-ETS) fusion gene and ETS related gene (ERG), ETS variant 1 (ETV1), phosphatase and tensin homolog deleted on chromosome 10 (PTEN), androgen receptor (AR) in prostate cancer. Methods A total of 50 cases of prostate cancer paraffin specimens and 30 cases of benign prostatic hyperplasia as the controls in the same period from the Third People's Hospital of Datong between December 2016 and October 2017 were collected. TMPRSS2-ERG, TMPRSS2-ETV1 and TMPRSS2-ETV4 gene fusion status were detected by using fluorescence in situ hybridization. Immunohistochemistry was used to detect the expressions of ERG, ETV1, PTEN and AR protein. Results In prostate cancer tissues, TMPRSS2-ETS fusion gene positive rate was 70％ (35/50), and TMPRSS2-ETS fusion gene was not detected in benign prostatic hyperplasia. The expression of TMPRSS2-ETS fusion gene in prostate cancer patients with different age, serum prostate specific antigen level and whether distant metastasis had no statistically significant differences (all P>0.05). The expression of TMPRSS2-ETS fusion gene in Gleason score>7 patients was higher than that in Gleason score≤7 patients (P< 0.05). The expressions of ERG and ETV1 in prostate cancer tissues werehigher than those in benign prostatic hyperplasia, and the differences were statistically significant (both P<0.05). The expression of PTEN in prostate cancer tissues was lower than that in benign prostatic hyperplasia (P< 0.05). There was no significant difference in the expression of AR between prostate cancer and benign prostatic hyperplasia tissues (P> 0.05). The expressions of TMPRSS2-ETS fusion gene and ERG in prostate cancer were positively correlated (r= 0.302, P< 0.05), and there was no correlation between the expression of TMPRSS2-ETS fusion gene and the expressions of ETV1, PTEN and AR (all P> 0.05). Conclusions The expressions of TMPRSS2-ETS fusion gene and ERG, ETV1 protein are upregulated in prostate cancer, which may involve in the occurrence and development of prostate cancer. The detection of TMPRSS2-ETS fusion genes and ERG protein can provide a reference for the diagnosis of prostate cancer.
