Preliminary evidence suggests that these programs may be helpful in reducing posttraumatic stress disorder(PTSD), anxiety, and depressive symptoms. The current study examines the acceptability of integrating an EAAT program as part of a two-week, intensive clinical program for veterans with PTSD and/or traumatic brain injury(TBI).Methods: A family member or support person could accompany veterans and participate in the program.One hundred and six participants(veteran n = 62, family n = 44) left the urban environment in an intensive outpatient program(IOP) to attend a two-day, weekend EAAT in rural New Hampshire. Satisfaction surveys were conducted on the last day of the program and examined using thematic analysis.Results: The following themes were reported in the surveys: ability of horses to catalyze emotional rehabilitation, effectiveness of immersion in equine-assisted activities, program’s ability to foster interpersonal relationships and necessity of education about PTSD for staff. Participants also reported enjoying the program as highlighted by qualitative feedback, a mean score of 9.76(standard deviation[SD] = 0.61) as reported by veterans and a mean score of 9.91(SD = 0.29) as reported by family members on a 10-point visual analog scale with higher scores indicating a greater overall experience.Conclusion: These data offer preliminary evidence that an adjunct EAAT program is acceptable for veterans with PTSD and/or TBI participating in an IOP.展开更多

Although complementary and alternative therapies are gaining acceptance in the treatment of PTSD, the efficacy of animal-based therapies in this disorder is unknown. The goal of equine-assisted psychotherapy(EAP) is to improve the social, emotional, and/or cognitive functions of individuals with PTSD.Objective: This study aims to explore the effects of EAP on PTSD symptoms. We hypothesized that veterans with PTSD who participate in a standardized EAP program for 1 h per week for 6 weeks would experience decreased PTSD symptoms and would demonstrate increased resilience as compared with individuals who do not receive EAP intervention.Design, setting, participants and interventions: We conducted a sequentially assigned, two-arm parallel group trial comparing 6 weeks of EAP with standard, previously established, ongoing PTSD therapy.Therapy was conducted at a community EAP facility in conjunction with an academic University Hospital. Twenty adult veterans with symptomatic PTSD completed the study. Ten adult veterans with previously diagnosed PTSD were assigned to EAP and received directed interaction with trained horses for one hour a week in groups of 3 or 4 individuals, while also continuing their previously established therapies. A certified therapist supervised the sessions, and a professional horse handler was also present.Results were compared with those from 10 adult veterans who only received their standard previously established PTSD care as prescribed by their provider.Main outcome measures: Changes in salivary cortisol, scores for the PTSD Check List-Military Version(PCL-M) and the Connor-Davidson Resilience Scale(CD-RISC) after 6 weeks of study were measured.Results: Of the 20 enrolled patients, 10 served in Afghanistan, 5 served in Iraq, and 3 served in Vietnam. Subjects were(47 ± 14) years old, were predominantly male, and had a body mass index of(29 ± 7) kg/m2. They had(9.2 ± 6.1) years of military service and carried 66% ± 37% service-connected disability. PCL-M scores declined significantly in both groups and CD-RISC scores increased significantly in the EAP group. There was no difference between the groups with respect to the magnitude of change.Conclusion: As compared to the control group, a 6-week EAP program did not produce a statistically significant difference with respect to PCL-M and CD-RISC scores, or salivary cortisol. However, our results suggest that EAP may work as well as standard therapy with respect to these parameters. This study supports further inquiry into EAP as a potentially efficacious alternative for veterans suffering from PTSD.Trial registration: ClinicalTrials.gov NCT #03039361.展开更多

Methods： The 91 PTSD patients in Wenchuan hit by a strong earthquake were randomly divided into a control group of 24 cases treated by the cognitive-behavior therapy, and a treatment group of 67 cases treated by both cognitive-behavior therapy and acupoint stimulation. The scores were evaluated according to Chinese version of the incident effect scale revised （IES-R） and the self-compiled questionnaire for the major post-traumatic psychological condition, and the curative effect was compared between the two groups. Results： The total scores of IES-R, the scores of all factors and the total scores of the questionnaire in the two groups after treatment were much lower than those before treatment （P〈0.01）. The comparison of reduction in the factor scores between the two groups showed that the curative effect inthe treatment group was better that of in the control group. Conclusion： The acupoint stimulation is effective for the PTSD patients, with better results than that of cognitive-behavior therapy used alone展开更多

Methods: We examine the effects of religious cognitive behavioral therapy (RCBT) vs. conventional CBT (CCBT) on pro-/anti-inflammatory indicators and stress hormones in 132 individuals with major depressive disorder (MDD) and chronic medical illness who were recruited into a multi-site randomized clinical trial. Biomarkers (C-reactive protein and pro-inflammatory cytokines TNF-α, IL-1β, IFN-γ, IL-6, IL-12-p70), anti-inflammatory cytokines (IL1ra, IL-4, IL-10), and stress hormones (urinary cortisol, epinephrine, norepinephrine) were assessed at baseline, 12 weeks, and 24 weeks. Differential effects of baseline religiosity on treatment response were also examined, along with effects of religiosity on changes in biomarkers over time independent of treatment group. Biomarker levels were log transformed where possible to normalize distributions. Mixed models were used to examine trajectories of change. Results: CRP increased and IL-4, IL-10, and epinephrine decreased over time, mostly in the opposite direction expected (except epinephrine). No significant difference between RCBT and CCBT was found on average trajectory of change in any biomarkers. Religiosity interacted with treatment group in effects on IL-6, such that CCBT was more effective than RCBT in lowering lL-6 in those with low religiosity whereas RCBT appeared to be more effective than CCBT in those with high religiosity. Higher baseline religiosity also tended to predict an increase in pro-inflammatory cytokines INF-γ and IL-12 (p70) and urinary cortisol over time. Conclusions: RCBT and CCBT had similar effects on stress biomarkers. CCBT was more effective in reducing IL-6 levels in those with low religiosity, whereas RCBT tended to be more effective in those with high religiosity. Unexpectedly, higher baseline religiosity was associated with an increase in several stress biomarkers.展开更多

Administration of a combination of isoniazid (INH ), rifampicin (RIF) and pyrazinamid e (PZA) increased plasma ATN in both groups of patients. ATN concentrations (M± SE) at six hours were higher (P <0.05 ) in elderly than in young patients on day one,8.22 ± 1.50 vs 1.89 ± 0.98 μg/mL); day 30, (5.85 ± 0.82 vs 0.87 ± 0.57 μg/mL; and day 90, (4.84 ± 1.24 vs 0.52 ± 0.50μg/mL). Because total amount of ATN excreted was similar in both groups on the three occasions, more ATN was formed in elderly than young patients. In conclusion, there was more oxidative stress in elderly than young patients. It is thereby suggested that Anti-TB drugs induce formation of ROS and elderly patients are at a greater risk of toxicity probably because of poor antioxidant mechanisms展开更多

The...Physical therapy students can experience elevated levels of stress due to the pressure to be successful, changes in the environment, personal concerns, the lack of spare time, increased work, or financial burdens. The purpose of this study was to examine the perceived stress and coping strategies of Doctor of Physical Therapy (DPT) students enrolled in a hybrid-learning curriculum during the COVID-19 pademic. A total of 73 students enrolled in the DPT hybrid-learning curriculum responded to a survey which consisted of socio-demographics, the 10-item Perceived Stress Scale (PSS), and the 28-item Brief COPE. A general question regarding stress relating to COVID-19 was presented as a sliding percentage. Data analysis included a Spearman correlation, a Kruskal-Wallis test, and a linear regression to evaluate coping mechanisms against PSS scores. The mean (± SD) score on the PSS was 22.65 (± 10.21) and the Brief COPE was 59.18 (± 10.61). A non-significant negative correlation was found between the PSS and Brief COPE (r = -0.024). A third of the variation in the perceived stress score could be accounted for by students utilizing coping mechanisms regardless of other factors (R<sup>2</sup> = 0.35). No significant differences were found when comparing PSS and Brief Cope to age, hours worked per week and term. Perceived stress was higher in females compared to males, but the results were not significant. Stress related to COVID-19 mean percentage reported by DPT students was 49.03%. During a global pandemic, DPT students enrolled in a hybrid-learning curriculum reported elevated levels of stress but reported higher adaptive versus maladaptive coping strategies. It can be beneficial that universities evaluate the stress and coping methods of students to potentially avoid the negative impacts of stress.展开更多

However, the therapeutic efficacy of CDT is restricted by insufficient H_(2)O_(2) levels in tumor cells. Herein, employing endogenous GSH as a template and cationic polymeric chitosan (CS) as crosslinker and stabilizer exhibiting easy cell uptake, red luminescent gold nanoclusters (denoted CS-GSH@AuNCs) were successfully synthesized in HeLa cells. The in situ synthesized CS-GSH@AuNCs exhibited both superoxidase dismutase (SOD) and peroxidase (POD)-like activity, which could promote the production of H_(2)O_(2) from superoxide anion radicals (O_(2)^(·-)) and then ^(·)OH. The combination of GSH elimination and H_(2)O_(2) elevation boosted the generation of ^(·)OH, which could trigger cancer cell apoptosis and death. The enzyme-like activity of CS-GSH@AuNCs could be effectively activated under acidic conditions, and showed a high killing effect on tumor cells but minimal toxicity to normal cells. The developed GSH consumption and ^(·)OH promotion theranostic platform is an innovative route for enhanced CDT by the amplification of oxidative stress.展开更多

Methods:A total of 138 patients with acute cerebral infarction between July 2016 and July 2017 were divided into control group (n=69) and triple group (n=69) by random number table method. Control group accepted conventional symptomatic treatment combined with aspirin and atorvastatin therapy, triple group accepted conventional symptomatic treatment combined with ganglioside, aspirin and atorvastatin triple therapy, and both groups were treated for 1 month. The differences in oxidative stress and inflammatory response were compared between the two groups before and after treatment. Results: Immediately after admission, There was no statistically significant difference in serum levels of oxidative stress indexes and inflammatory mediators between the two groups. After 1 week of treatment and after 4 weeks of treatment, serum oxidative stress indexes ROS and AOPPs levels of triple group were lower than those of control group whereas SOD and CAT contents were higher than those of control group;serum inflammatory mediators IL-6, TNF-α and TGF-β levels were lower than those of control group whereas IL-4, IL-10 and IL-13 levels were higher than those of control group. Conclusion: ganglioside + aspirin + atorvastatin triple therapy can effectively inhibit the systemic oxidative stress and inflammatory response in patients with cerebral infarction.展开更多

Methods: A total of 140 patients with coronary artery disease who underwent percutaneous coronary intervention in our hospital from October 2016 to March 2018 were selected as the study subjects and were divided into control group (70 cases) and observation group (70 cases) by drawing lots. Both groups were treated with symptomatic routine therapy before operation. On this basis, the control group was treated with clopidogrel before operation, and the observation group was treated with Ticagrelor before operation on the basis of routine treatment. The changes of oxidative stress, coagulation index, platelet function and related factors were compared between the two groups before and after treatment. Results: Before treatment, there were no significant differences in oxidative stress factors, coagulation parameters, platelet parameters and related factors factors between the two groups. After treatment, the levels of MDA, MPAR, VEGF and MMP-9 in the two groups were lower than those before treatment, while the levels of SOD, APTT, TT and PT were higher than those before treatment;and the levels of MDA, MPAR, VEGF, MMP-9, APTT and PT in the observation group were significantly lower than those in the control group after treatment, while the levels fo SOD, TT and IPA in the observation group were significantly higher than those in the control group. Conclusions: Ticagrelor can better reduce oxidative stress injury, improve coagulation function and coronary stenosis, and inhibit platelet aggregation in patients with coronary heart disease undergoing PCI than clopidogrel. It has clinical popularization significance.展开更多

文摘Effective treatment methods for stroke,a common cerebrovascular disease with a high mortality rate,are still being sought.Exosome therapy,a form of acellular therapy,has demonstrated promising efficacy in various diseases in animal models;however,there is currently insufficient evidence to guide the clinical application of exosome in patients with stroke.This article reviews the progress of exosome applications in stroke treatment.It aims to elucidate the significant potential value of exosomes in stroke therapy and provide a reference for their clinical translation.At present,many studies on exosome-based therapies for stroke are actively underway.Regarding preclinical research,exosomes,as bioactive substances with diverse sources,currently favor stem cells as their origin.Due to their high plasticity,exosomes can be effectively modified through various physical,chemical,and genetic engineering methods to enhance their efficacy.In animal models of stroke,exosome therapy can reduce neuroinflammatory responses,alleviate oxidative stress damage,and inhibit programmed cell death.Additionally,exosomes can promote angiogenesis,repair and regenerate damaged white matter fiber bundles,and facilitate the migration and differentiation of neural stem cells,aiding the repair process.We also summarize new directions for the application of exosomes,specifically the exosome intervention through the ventricular-meningeal lymphatic system.The review findings suggest that the treatment paradigm for stroke is poised for transformation.

文摘Objective: Equine-assisted activities and therapies(EAATs) have been a growing adjunctive integrative health modality, as they allow participants to practice mindfulness, emotional regulation, and self-mastery or self-esteem building skills. Preliminary evidence suggests that these programs may be helpful in reducing posttraumatic stress disorder(PTSD), anxiety, and depressive symptoms. The current study examines the acceptability of integrating an EAAT program as part of a two-week, intensive clinical program for veterans with PTSD and/or traumatic brain injury(TBI).Methods: A family member or support person could accompany veterans and participate in the program.One hundred and six participants(veteran n = 62, family n = 44) left the urban environment in an intensive outpatient program(IOP) to attend a two-day, weekend EAAT in rural New Hampshire. Satisfaction surveys were conducted on the last day of the program and examined using thematic analysis.Results: The following themes were reported in the surveys: ability of horses to catalyze emotional rehabilitation, effectiveness of immersion in equine-assisted activities, program’s ability to foster interpersonal relationships and necessity of education about PTSD for staff. Participants also reported enjoying the program as highlighted by qualitative feedback, a mean score of 9.76(standard deviation[SD] = 0.61) as reported by veterans and a mean score of 9.91(SD = 0.29) as reported by family members on a 10-point visual analog scale with higher scores indicating a greater overall experience.Conclusion: These data offer preliminary evidence that an adjunct EAAT program is acceptable for veterans with PTSD and/or TBI participating in an IOP.
文摘Background: Posttraumatic stress disorder(PTSD) is a common and debilitating disorder among war veterans. Although complementary and alternative therapies are gaining acceptance in the treatment of PTSD, the efficacy of animal-based therapies in this disorder is unknown. The goal of equine-assisted psychotherapy(EAP) is to improve the social, emotional, and/or cognitive functions of individuals with PTSD.Objective: This study aims to explore the effects of EAP on PTSD symptoms. We hypothesized that veterans with PTSD who participate in a standardized EAP program for 1 h per week for 6 weeks would experience decreased PTSD symptoms and would demonstrate increased resilience as compared with individuals who do not receive EAP intervention.Design, setting, participants and interventions: We conducted a sequentially assigned, two-arm parallel group trial comparing 6 weeks of EAP with standard, previously established, ongoing PTSD therapy.Therapy was conducted at a community EAP facility in conjunction with an academic University Hospital. Twenty adult veterans with symptomatic PTSD completed the study. Ten adult veterans with previously diagnosed PTSD were assigned to EAP and received directed interaction with trained horses for one hour a week in groups of 3 or 4 individuals, while also continuing their previously established therapies. A certified therapist supervised the sessions, and a professional horse handler was also present.Results were compared with those from 10 adult veterans who only received their standard previously established PTSD care as prescribed by their provider.Main outcome measures: Changes in salivary cortisol, scores for the PTSD Check List-Military Version(PCL-M) and the Connor-Davidson Resilience Scale(CD-RISC) after 6 weeks of study were measured.Results: Of the 20 enrolled patients, 10 served in Afghanistan, 5 served in Iraq, and 3 served in Vietnam. Subjects were(47 ± 14) years old, were predominantly male, and had a body mass index of(29 ± 7) kg/m2. They had(9.2 ± 6.1) years of military service and carried 66% ± 37% service-connected disability. PCL-M scores declined significantly in both groups and CD-RISC scores increased significantly in the EAP group. There was no difference between the groups with respect to the magnitude of change.Conclusion: As compared to the control group, a 6-week EAP program did not produce a statistically significant difference with respect to PCL-M and CD-RISC scores, or salivary cortisol. However, our results suggest that EAP may work as well as standard therapy with respect to these parameters. This study supports further inquiry into EAP as a potentially efficacious alternative for veterans suffering from PTSD.Trial registration: ClinicalTrials.gov NCT #03039361.

文摘The endoplasmic reticulum(ER),an organelle present in various eukaryotic cells,is responsible for intracellular protein synthesis,post-translational modification,and folding and transport,as well as the regulation of lipid and steroid metabolism and Ca2+homeostasis.Hypoxia,nutrient deficiency,and a low pH tumor microenvironment lead to the accumulation of misfolded or unfolded proteins in the ER,thus activating ER stress(ERS)and the unfolded protein response,and resulting in either restoration of cellular homeostasis or cell death.ERS plays a crucial role in cancer oncogenesis,progression,and response to therapies.This article reviews current studies relating ERS to ovarian cancer,the most lethal gynecologic malignancy among women globally,and discusses pharmacological agents and possible targets for therapeutic intervention.
文摘BACKGROUND Femoral neck stress fractures are rarely encountered among young adults and are often associated with either repetitive excessive loading or underlying bone pathology.Preliminary research has indicated human immunodeficiency virus(HIV)/antiretroviral therapy(ART)as predisposing agents to osteopenia and osteoporosis related complications.We report a case of HIV/ART induced insufficiency fracture in a resource limited setting in Central India.Our aim is to increase awareness and promote screening of HIV/ART related osteopenia and osteoporosis in order to prevent catastrophic orthopaedic complications.CASE SUMMARY A 35-year-old HIV positive male presented with a stress fracture of left femoral neck.The patient was on ART and reported no comorbidities.He went on to be successfully managed surgically.However,during work-up osteopenia of the contralateral proximal femur was recognised using Singh’s Index.Six months post-op the patient presented with right-sided femoral-neck stress fracture.At this stage the patient was nonconcordant with ART and denied surgical fixation.CONCLUSION In the absence of co-morbidities,several mechanisms of HIV/antiretroviral therapy may have played a role in predisposing our patient towards such a presentation.We recommend routine screening all HIV-infected patients for osteopenia,especially in younger individuals.In low resource settings and district hospitals,pelvis radiograph&Singh’s index can be used for screening.
文摘Objective： To study the curative effect of acupoint stimulation on the earthquake-caused post-traumatic stress disorder （PTSD）. Methods： The 91 PTSD patients in Wenchuan hit by a strong earthquake were randomly divided into a control group of 24 cases treated by the cognitive-behavior therapy, and a treatment group of 67 cases treated by both cognitive-behavior therapy and acupoint stimulation. The scores were evaluated according to Chinese version of the incident effect scale revised （IES-R） and the self-compiled questionnaire for the major post-traumatic psychological condition, and the curative effect was compared between the two groups. Results： The total scores of IES-R, the scores of all factors and the total scores of the questionnaire in the two groups after treatment were much lower than those before treatment （P〈0.01）. The comparison of reduction in the factor scores between the two groups showed that the curative effect inthe treatment group was better that of in the control group. Conclusion： The acupoint stimulation is effective for the PTSD patients, with better results than that of cognitive-behavior therapy used alone
文摘BACKGROUND The degree of psychological stress and the difficulty and efficacy of laparoscopic surgery differ in patients with pelvic abscesses after different durations of antiinfection treatment.AIM To compare and analyse the effects of different durations of anti-infective therapy on patients’preoperative psychological stress level and the clinical efficacy of laparoscopic surgery in patients with pelvic abscesses to offer a reference for the selection of therapy plans.METHODS A total of 100 patients with pelvic abscesses who were admitted to the Department of Gynecology of Suzhou Ninth Hospital affiliated to Soochow University(Suzhou Ninth People's Hospital)from January 2018 to December 2022 were retrospectively enrolled.According to the different durations of antiinfective therapy,they were divided into Group S(50 patients,received antiinfective therapy for 24-48 h)and Group L(50 patients,received anti-infective therapy for 48-96 h).Baseline data,state-trait anxiety score at admission and before surgery,self-rating anxiety scale(SAS)+self-rating depression scale(SDS)score,surgery time,adhesion grading score,intraoperative blood loss,presence or absence of intraoperative intestinal injury,ureteral injury or bladder injury,postoperative body temperature,length of hospital stay,and presence or absence of recurrence within 3 mo after surgery,chronic pelvic pain,incision infection,dysmenorrhea,menstrual disorder or intestinal obstruction were compared between the S group and the L group.RESULTS There was no significant difference in the background data between the S group and the L group(P<0.05).There was no significant difference in the state-trait anxiety score or SAS+SDS score between the S group and the L group on admission(P<0.05).The state-trait anxiety score and SAS+SDS score of the S group were lower than those of Group L after receiving different durations of anti-infective therapy(P<0.05).There was no significant difference in the incidence of intestinal,ureteral or bladder injury between the S group and the L group(P<0.05).The surgery time of Group S was shorter than that of Group L,and the adhesion score and intraoperative blood loss volume were lower than those of Group L(P<0.05).There was no significant difference in the incidence of incision infection,dysmenorrhea,menstrual disorder or intestinal obstruction between the S group and the L group(P<0.05).The postoperative body temperature of Group S was lower than that of Group L(P<0.05),and the hospital stay was shorter than that of Group L(P<0.05).The incidences of recurrence and chronic pelvic pain within 3 mo after surgery were lower than that of Group L(P<0.05).CONCLUSION Twenty-four to forty-eight hours of anti-infective therapy is better than 48-96 h of anti-infective therapy for patients with pelvic abscesses because the degree of psychological stress is lower,which is more conducive to achieving better outcomes after laparoscopic surgery.
文摘Background: Depressive disorder is often accompanied by physiological changes that may adversely affect the course of medical illness, including an increase in pro-inflammatory cytokines. Methods: We examine the effects of religious cognitive behavioral therapy (RCBT) vs. conventional CBT (CCBT) on pro-/anti-inflammatory indicators and stress hormones in 132 individuals with major depressive disorder (MDD) and chronic medical illness who were recruited into a multi-site randomized clinical trial. Biomarkers (C-reactive protein and pro-inflammatory cytokines TNF-α, IL-1β, IFN-γ, IL-6, IL-12-p70), anti-inflammatory cytokines (IL1ra, IL-4, IL-10), and stress hormones (urinary cortisol, epinephrine, norepinephrine) were assessed at baseline, 12 weeks, and 24 weeks. Differential effects of baseline religiosity on treatment response were also examined, along with effects of religiosity on changes in biomarkers over time independent of treatment group. Biomarker levels were log transformed where possible to normalize distributions. Mixed models were used to examine trajectories of change. Results: CRP increased and IL-4, IL-10, and epinephrine decreased over time, mostly in the opposite direction expected (except epinephrine). No significant difference between RCBT and CCBT was found on average trajectory of change in any biomarkers. Religiosity interacted with treatment group in effects on IL-6, such that CCBT was more effective than RCBT in lowering lL-6 in those with low religiosity whereas RCBT appeared to be more effective than CCBT in those with high religiosity. Higher baseline religiosity also tended to predict an increase in pro-inflammatory cytokines INF-γ and IL-12 (p70) and urinary cortisol over time. Conclusions: RCBT and CCBT had similar effects on stress biomarkers. CCBT was more effective in reducing IL-6 levels in those with low religiosity, whereas RCBT tended to be more effective in those with high religiosity. Unexpectedly, higher baseline religiosity was associated with an increase in several stress biomarkers.
文摘It has been observed that managing job burnout and dysfunctional distress constitute part of the major challenges among special educators,and that empirical data on the management of burnout and dysfunctional distress associated with the job of special education teachers are lacking in the literature.The current article discusses the clinical benefits of a rational-emotive stressmanagement therapy program in reducing the level of job burnout symptoms and dysfunctional distress in special education teachers,using evidence from a 2018 clinical trial study that reported the efficacy of this intervention.Results show the clinical benefits and implications of conducting a rational-emotive stress management intervention,and recommendations are made for future research.
文摘Using allantoin (ATN ) as a marker for reactive oxygen species (ROS), oxidative stress during antituberculous (anti-TB) therapy was compared in 10 young and 9 elderly patients.Before treatment, ATN plasma concentrations in patients were similar to that of volunteers. Administration of a combination of isoniazid (INH ), rifampicin (RIF) and pyrazinamid e (PZA) increased plasma ATN in both groups of patients. ATN concentrations (M± SE) at six hours were higher (P <0.05 ) in elderly than in young patients on day one,8.22 ± 1.50 vs 1.89 ± 0.98 μg/mL); day 30, (5.85 ± 0.82 vs 0.87 ± 0.57 μg/mL; and day 90, (4.84 ± 1.24 vs 0.52 ± 0.50μg/mL). Because total amount of ATN excreted was similar in both groups on the three occasions, more ATN was formed in elderly than young patients. In conclusion, there was more oxidative stress in elderly than young patients. It is thereby suggested that Anti-TB drugs induce formation of ROS and elderly patients are at a greater risk of toxicity probably because of poor antioxidant mechanisms

文摘The objective of this systematic review is to examine the effectiveness of psychotherapy in treating Post-Traumatic Stress Disorder(PTSD)in military personnel.PubMed,Web of Science,The Cochrane Library,EBSCO and CNKI databases were searched from 1 January,2000 to November 2022 for Randomized Controlled Trials(RCTs)on psychotherapeutic interventions for military PTSD.The physical Therapy Evidence Database(PEDro)scale was used to evaluate the quality of the literature.Two researchers conducted literature screening,data extraction,and risk bias assessment in accordance with inclusion and exclusion criteria.Ultimately,49 RCTs were included,involving a total of 5073 veterans,retired and active military from four countries.The average score on the PEDro scale was 7.60.The primary psychotherapeutic modalities for military PTSD intervention include Cognitive-Behavioral Therapy,Exposure Therapy,Mindfulness interventions,psychotherapy based on new technological tools,and other emerging psychotherapeutic tools.The review highlights that Cognitive Processing Therapy(CPT)and Prolonged Exposure Therapy(PET)stand out as the primary psychotherapeutic modalities for treating PTSD in military personnel.In cases where CPT and PET yield limited benefits,Mindfulness interventions emerge as effective alternatives.Moreover,considering the diverse needs and high dropout rates in the military,population,the review suggests using web-based,computer,and virtual reality technology tools as supplements to first-line treatments(CPT/PET)to enhance overall intervention effectiveness.For the advancement of future psychotherapeutic initiatives,there is a pronounced emphasis on prioritizing proven first-line interventions,CPT and PET while also recognizing the potential of mindfulness-based interventions as credible alternatives.In tandem with this,the active integration of technological tools is advocated to amplify the therapeutic impact of conventional psychological treatment modalities.
文摘Physical therapy students can experience elevated levels of stress due to the pressure to be successful, changes in the environment, personal concerns, the lack of spare time, increased work, or financial burdens. The purpose of this study was to examine the perceived stress and coping strategies of Doctor of Physical Therapy (DPT) students enrolled in a hybrid-learning curriculum during the COVID-19 pademic. A total of 73 students enrolled in the DPT hybrid-learning curriculum responded to a survey which consisted of socio-demographics, the 10-item Perceived Stress Scale (PSS), and the 28-item Brief COPE. A general question regarding stress relating to COVID-19 was presented as a sliding percentage. Data analysis included a Spearman correlation, a Kruskal-Wallis test, and a linear regression to evaluate coping mechanisms against PSS scores. The mean (± SD) score on the PSS was 22.65 (± 10.21) and the Brief COPE was 59.18 (± 10.61). A non-significant negative correlation was found between the PSS and Brief COPE (r = -0.024). A third of the variation in the perceived stress score could be accounted for by students utilizing coping mechanisms regardless of other factors (R<sup>2</sup> = 0.35). No significant differences were found when comparing PSS and Brief Cope to age, hours worked per week and term. Perceived stress was higher in females compared to males, but the results were not significant. Stress related to COVID-19 mean percentage reported by DPT students was 49.03%. During a global pandemic, DPT students enrolled in a hybrid-learning curriculum reported elevated levels of stress but reported higher adaptive versus maladaptive coping strategies. It can be beneficial that universities evaluate the stress and coping methods of students to potentially avoid the negative impacts of stress.

文摘Chemodynamic therapy (CDT) has attracted tremendous interest in cancer therapy because it is independent of oxygen and photoirradiation. However, the therapeutic efficacy of CDT is restricted by insufficient H_(2)O_(2) levels in tumor cells. Herein, employing endogenous GSH as a template and cationic polymeric chitosan (CS) as crosslinker and stabilizer exhibiting easy cell uptake, red luminescent gold nanoclusters (denoted CS-GSH@AuNCs) were successfully synthesized in HeLa cells. The in situ synthesized CS-GSH@AuNCs exhibited both superoxidase dismutase (SOD) and peroxidase (POD)-like activity, which could promote the production of H_(2)O_(2) from superoxide anion radicals (O_(2)^(·-)) and then ^(·)OH. The combination of GSH elimination and H_(2)O_(2) elevation boosted the generation of ^(·)OH, which could trigger cancer cell apoptosis and death. The enzyme-like activity of CS-GSH@AuNCs could be effectively activated under acidic conditions, and showed a high killing effect on tumor cells but minimal toxicity to normal cells. The developed GSH consumption and ^(·)OH promotion theranostic platform is an innovative route for enhanced CDT by the amplification of oxidative stress.
文摘Objective: To investigate the effects of ganglioside + aspirin + atorvastatin triple therapy on oxidative stress and inflammatory response in patients with cerebral infarction. Methods:A total of 138 patients with acute cerebral infarction between July 2016 and July 2017 were divided into control group (n=69) and triple group (n=69) by random number table method. Control group accepted conventional symptomatic treatment combined with aspirin and atorvastatin therapy, triple group accepted conventional symptomatic treatment combined with ganglioside, aspirin and atorvastatin triple therapy, and both groups were treated for 1 month. The differences in oxidative stress and inflammatory response were compared between the two groups before and after treatment. Results: Immediately after admission, There was no statistically significant difference in serum levels of oxidative stress indexes and inflammatory mediators between the two groups. After 1 week of treatment and after 4 weeks of treatment, serum oxidative stress indexes ROS and AOPPs levels of triple group were lower than those of control group whereas SOD and CAT contents were higher than those of control group;serum inflammatory mediators IL-6, TNF-α and TGF-β levels were lower than those of control group whereas IL-4, IL-10 and IL-13 levels were higher than those of control group. Conclusion: ganglioside + aspirin + atorvastatin triple therapy can effectively inhibit the systemic oxidative stress and inflammatory response in patients with cerebral infarction.
文摘Objective: To explore the effects of Ticagrelor on oxidative stress, coagulation function, platelet function and related factors in patients with coronary artery disease undergoing interventional therapy. Methods: A total of 140 patients with coronary artery disease who underwent percutaneous coronary intervention in our hospital from October 2016 to March 2018 were selected as the study subjects and were divided into control group (70 cases) and observation group (70 cases) by drawing lots. Both groups were treated with symptomatic routine therapy before operation. On this basis, the control group was treated with clopidogrel before operation, and the observation group was treated with Ticagrelor before operation on the basis of routine treatment. The changes of oxidative stress, coagulation index, platelet function and related factors were compared between the two groups before and after treatment. Results: Before treatment, there were no significant differences in oxidative stress factors, coagulation parameters, platelet parameters and related factors factors between the two groups. After treatment, the levels of MDA, MPAR, VEGF and MMP-9 in the two groups were lower than those before treatment, while the levels of SOD, APTT, TT and PT were higher than those before treatment;and the levels of MDA, MPAR, VEGF, MMP-9, APTT and PT in the observation group were significantly lower than those in the control group after treatment, while the levels fo SOD, TT and IPA in the observation group were significantly higher than those in the control group. Conclusions: Ticagrelor can better reduce oxidative stress injury, improve coagulation function and coronary stenosis, and inhibit platelet aggregation in patients with coronary heart disease undergoing PCI than clopidogrel. It has clinical popularization significance.
