Post-traumatic stress disorder(PTSD),as a mental disorder disease,can seriously damage the physical and mental health and social functioning of patients.Physical therapy is increasingly being used in research on the treatment of PTSD due to its ability to directly target specific brain regions and improve the core symptoms of PTSD.This review categorizes on physical therapy for PTSD into two categories:non-invasive physical therapy and invasive physical therapy.Non-invasive physical therapy methods included electroconvulsive therapy,transcranial direct current stimulation,transcranial magnetic stimulation,and the Flexyx neurotherapy system.Non-invasive physical therapy had the advantages of safety,convenience,and simple operation.However,their stimulation accuracy was limited.Invasive physical therapy methods included deep brain stimulation and stellate ganglion block.Invasive physical therapy had the advantages of precise stimulation,fewer adverse reactions.However,there were surgical risks,high operational difficulty,and high treatment costs.In addition,potential physical therapy methods included transcranial alternating current stimulation,magnetic seizure therapy,and vagus nerve stimulation,which were currently in the theoretical research stage.This study discussed the mechanism of action,therapeutic parameters,clinical efficacy,adverse effects and the latest forms of technology of the above physical therapy methods,so as to provide reference for the treatment of PTSD.

Objective:This study explored the impacts of repetitive transcranial magnetic stimulation (rTMS) on spontaneous brain activity in patients with major depressive disorder (MDD).Methods:This study was a randomized controlled study. First-episode, drug-na?ve patients with MDD ( n=27) and healthy controls ( n=30) were enrolled. The left dorsolateral prefrontal region was the stimulation target, and all participants received rTMS treatment for fifteen successive days. Hamilton Depression Rating Scale (HAMD 17) and resting-state functional magnetic resonance imaging (rs-fMRI) data were collected at baseline and the 15th day of the treatment. Changes in the spontaneous brain activity before and after the treatment were compared using the paired samples t-test or the independent sample t-test. The two indices of the amplitude of the low-frequency fluctuation (ALFF) and regional homogeneity(ReHo) were applied to reflect the spontaneous brain activity. Results:After treatment, the score of HAMD 17 (9.4±4.3) in MDD patients was significantly lower than that before the treatment (21.1±6.0), the average score decreased by (11.7±3.6), the remission rate was 40.74%, and the response rate was 74.07%. fMRI results: Before treatment, patients with MDD had significantly lower ALFF in the left superior frontal gyrus ( t=-8.14, P<0.001), higher ALFF in the left middle frontal gyrus and left precuneus ( t=5.79, 6.24, P<0.001), and lower ReHo in the left middle frontal and left middle occipital gyri ( t=-5.17, -6.11, P<0.001) than the corresponding values observed in healthy controls; After the rTMS treatment, the ALFF significantly increased in the left superior frontal gyrus ( t=7.32, P<0.001) and decreased in the left middle frontal gyrus and left precuneus ( t=-4.96,-5.14, P<0.001). Furthermore, ReHo significantly increased in the left middle frontal and left middle occipital gyri ( t=4.25,4.19, P<0.001) in patients with MDD. The score of HAMD 17 after treatment was significantly and negatively correlated with ALFF value of left superior frontal gyrus after treatment ( r=-0.390, P=0.044). Conclusion:Successive 15-day rTMS treatment could efficiently and effectively alleviate individual′s depressive symptoms. The left middle frontal gyrus may play an important role in abnormal spontaneous brain activity in MDD patients; and left superior frontal gyrus function may be essential in improving depressive symptoms.

Objective:To investigate whether irradiated U251 glioma cells can induce bystander effects in unexposed neural stem cells (NSCs) thus affecting its proliferation, stemness and differentiation.Methods:The cells were divided into NSCs group, NSCs+ U251 group (co-cultured with U251) and NSCs+ IR U251 group (co-cultured with 10 Gy irradiated U251). Glioma cells and NSCs were co-cultured in a transwell insert set. Cell counting and neurosphere diameter measuring were carried out to evaluate the proliferation and neurosphere formation ability of NSCs. Immunofluorescence assay was performed to detect the expression of Nestin protein to evaluate the stemness maintenance of NSCs, and to measure the expression levels of Tuj1 and GFAP proteins, the number of neuronal dendrites, synaptic length, the number of glial protrusions, as well as the length of glial protrusions.Results:The number of NSCs cultured with irradiated U251 cells was obviously smaller than that of NSCs cultured with sham-irradiated U251 cells ( t=2.52, P<0.05). The neurosphere formation ability of NSCs and the percentage of Nestin positive NSCs after co-culture with irradiated U251 cells significantly reduced in comparison with those after co-culture with sham-irradiated U251 cells ( t=-3.50, P<0.05). The percentages and the extent of NSCs differentiating into neuronal cells and glial cells( t=6.09, P<0.05)decreased obviously after co-culture with irradiated U251 cells in comparison with those after co-culture with sham-irradiated U251 cells. Conclusions:Irradiated glioma cells can significantly inhibit the proliferation, stemness and differentiation of unexposed NSCs due to bystander effect.

Objective To investigate the pathogenesis characteristics and epidemic tendency of notifiable infectious diseases (NID) in Zhujing County of Shanghai from 2013 to 2017, and to provide scientific basis for effective prevention and control measures. Methods Descriptive epidemiological method was used to statistically analyze the epidemic data of NID in Zhujing County of Shanghai during 2013-2017 reported by the China Information System for Disease Control and Prevention. Results A total of 3 259 cases of 17 different NID were reported in Zhujing County of shanghai during 2013-2017.The average annual incidence rate was 509.89/10⁵, A total of 7 cases of death were reported and average annual rate of mortality was 1.10/10⁵.No type A NID was reported and a total of 1 089 cases of 13 type B NID were reported, with the average annual incidence rate of type A and B NID being 170.38/10⁵; a total of 2 170 cases of 4 type C NID were reported, with the average annual incidence rate of type C NID being 339.51/10⁵. The top 5 diseases were HFMD, influenza, syphilis, gonorrhea and tuberculosis, accounting for 32.46%, 25.65%, 17.40%, 7.24% and 5.43% of the total.The onset was mainly to occur from May to August and from December to January, mostly in 0-6 years and 18-40 years groups.Most of the cases were students, scattered children, nursery children, farmers, workers.The incidence rate was higher in men than in women, and the incidence rate of household-registered residents in this city was higher than that of floating population.Intestinal infectious diseases were the main components. Conclusion As HFMD, influenza, syphilis, gonorrhea, tuberculosis prove to be the key NID in Zhujing County of Shanghai, we should act according to the epidemic features of the infectious diseases to formulate perfect control strategy to prevent the outbreak and prevalence of infectious diseases.
