Methods： From June 2015 to March 2016, 60 cancer patients were included into the study. The patients were randomly assigned to a control group and a treatment group by envelope randomization, receiving PMRT and PMRT plus CM five elements music therapy, respectively, for 8 weeks. Hospital Anxiety and Depression Scale （HADS）, Benefit Finding Scales （BFS）, Functional Assessment of Chronic Illness Therapy-Spiritual （FACIT-Sp）, and Intervention Expectations Questionnaire （IEQU） were adopted to assess the depression of the two groups before and after the treatment. Results： Four cases dropped out during the study, and 29 cases in the treatment group and 27 in the control group were included in the final analysis. Prior to the treatments, the baselines of the 4 questionnaires in the two groups showed no difference. After the 8-week treatment, the treatment group presented better levels of HADS, BFS and FACIT-Sp scores compared with the control group （P〈0.05）. Among the single items of HADS, 4 items involving vexation, feeling fidgeted, pleasure and prospecting the future in the treatment group were improved compared with the control group （P〈0.05）. Conclusions： As a simple and reliable and effective intervention, PMRT combined with five elements music therapy mitigated anxiety and depression of cancer patients. Cancer patients have been found to respond well to psychological intervention in areas regarding stabilisation of emotions, disease awareness, and therapeutic compliance. This brings about a great difference in improving their quality of life and psychological state, offers an effective approach to better self-management in cancer treatment.展开更多

All groups were given basic therapies for cerebral infarction. In addition,the control group was administerd 50 mg of oral sertraline hydrochloride daily, while treatment groups A and B received needling at Baihui(GV 20)plus acupoint injection at Yanglingquan(GB 34) daily; treatment group B also received music therapy derived from the five phases in Traditional ChineseMedicine theory twice daily. All treatments were administered for 5 d per treatment cycle for three cycles, with a 1 d interval between cycles. In all three groups, Hamilton's depression scale(HAMD-17)score and the activities of daily life(ADL) score were measured before and after treatment, and side effects were assessed with the treatment emergent symptom scale.RESULTS: The HAMD-17 score significantly decreased after treatment in all three groups, and the post-treatment reduction in HAMD-17 score was markedly greater in treatment group B than in treatment group A(P < 0.01). The ADL score significantly increased after treatment in all three groups,and the post-treatment increase in ADL score was significantly greater in treatment group B than in treatment group A(P < 0.01). The treatment emergent symptom scale score was highest in the control group, and lowest in group B, and significantly differed between the three groups(P < 0.01).CONCLUSION: Five phase music therapy plus acupoint needling and acupoint injection can improve the symptoms in patients with post-stroke depression.展开更多

We then calculated the detectable rate of PU(DRPU) during each season every five days (FD) and made a correlated analysis with the seasonal MF during the same period in Nanning. Finally, we made a multiple regressive correlated analysis of DRPU and the 5MF for the same period of the year. A forecast model based on the MF of the previous FD was established. The real value and the forecast value was being tested and verified. Results From 1992 to 1997, the DRPU is: winter and spring>summer and autumn (P<0.005). There is a close relationship between the DRPU and the average temperature (AT), the average highest temperature (AHT), the average lowest temperature (ALT), average air pressure (AAP) and the average dew point temperature (ADT) of the five days of the same period of the year (the correlated coefficients are -0.5348,-05167, -0.5384, 0.4579 and -0.4936, respectively), with P<0.01. The AT, AHT, ALT, AAP and ADT of the previous FD are of great value in forecasting the onset of PU, with its real value and forecast value corresponding to 66.6%.Conclusions There exists a close relationship between DRPU and the AT, AHT, ALT, AAP and ADT of the FD for the same period. A mid-term medical meteorological forecast of the onset of PU can be made more accurately and reliably according to the close relation betweenthe DRPU and some MF of the previous FD.展开更多

Methods： Data regarding the incidence of tuberculosis between 1990 and 2004 were obtained from the Beijing Center for Disease Control and Prevention, and the data regarding the meteorological factors （including daily average temperatures, wind speeds, precipitations, relative humidities, vapor pressures and low cloud covers） between 1987 and 2004 were collected from the Beijing Meteorological Observatory and analyzed. Descriptive statistics and a back-propagation artificial neural network were adopted to analyze the data. Results： There were significant correlations between the incidence of tuberculosis and the meteorological factors in the corresponding year and previous years. Among these correlations, wind speed was the factor with the strongest influence on tuberculosis （the standardized significance was 100%）. Additionally, all prediction models would successfully established, suggesting the use of a collection of meteorological factors spanning from three years ago to the present is superior to the use of single data. Conclusions： The incidence of tuberculosis in Beijing area is correlated to meteorological factors in the current year and previous years, which verifies the practicality of the theory of five circuits and six qi.展开更多

In treatment group,the back-shu points of five zang organs were adopted for acupuncture. Shènshū(肾俞 BL23) was perpendicularly needled 15-30 mm in depth. The rest of the selected points were inserted obliquely 15-30 mm in the direction of the spine with even method of lifting-thrusting and twisting-twirling, 10 s for each acupoint. In control group, the acupoints were approximately 1.5-2 cm away outward from the back-shu points of five zang organs(about on the middle of the two sidelines of the bladder meridian of foottaiyang) and the points from the bladder meridian of foot-taiyang were excluded. Acupoints were needled6-9 mm in depth, and deqi was not required, without any manipulation. The treatments were carried out twice a week for twenty minutes each time, a total of eight treatments were given. The clinical efficacy of acupuncture treatment for CFS was evaluated through the Fatigue Scale-14(FS-14) and the Symptom Check-List 90(SCL-90) after treatment.Results: The total effective rate was 86.67% in the treatment group and 53.33% in the control group(P<0.01). In treatment group, FS-14 total scores, somatic fatigue scores, and mental fatigue scores were significantly reduced than before treatment(all P<0.01). In control group, FS-14 total scores and somatic fatigue scores were significantly reduced(both P<0.01). The improvement of FS-14 total scores, somatic fatigue scores, and mental fatigue scores in the treatment group were better than those in the control group(P<0.01, P<0.05). After treatment, SCL-90 total scores and somatization, compulsion, interpersonal sensitivity, depression, anxiety, hostility, psychoticism, and other factors scores were significantly reduced in the treatment group compared with before treatment(P<0.01).

The impact of “Big Five” on physical health is here explored for older Europeans with a focus on examining age groups differences. The study sample included 378,500 respondents derived from the seventh data wave of Survey of Health, Aging and Retirement in Europe (SHARE). The physical health status of older Europeans was estimated by constructing an index considering the combined effect of well-established health indicators such as the number of chronic diseases, mobility limitations, limitations with basic and instrumental activities of daily living, and self-perceived health. This index was used for an overall physical health assessment, for which the higher the score for an individual, the worst health level. Then, through a dichotomization process applied to the retrieved Principal Component Analysis scores, a two-group discrimination (good or bad health status) of SHARE participants was obtained as regards their physical health condition, allowing for further con-structing logistic regression models to assess the predictive significance of “Big Five” and their protective role for physical health. Results showed that neuroti-cism was the most significant predictor of physical health for all age groups un-der consideration, while extraversion, agreeableness and openness were not found to significantly affect the self-reported physical health levels of midlife adults aged 50 up to 64. Older adults aged 65 up to 79 were more prone to open-ness, whereas the oldest old individuals aged 80 up to 105 were mainly affected by openness and conscientiousness. .展开更多

文摘Objective：To investigate the relationship between respiratory diseases onset and the meteorological factors in the same period and in a specific environment.Methods：By using the data of daily incidence of respiratory diseases obtained from Dongzhimen Hospital Affiliated to Beijing University of Chinese Medicine from January 1, 1998 to December 31,2007,and the data of 16 items of meteorological factors（such as the average,maximum, and minimum temperatures,etc.,including meteorological factors derived） obtained from the Beijing Municipal Meteorological Observatory,mathematical statistical methods were applied to achieve the non-linear correlation analysis,or the correlation test,between the incidence of respiratory diseases and the time-related meteorological factors.Results：The simple correlation coefficients of the relationship between the incidence of respiratory diseases and 9 meteorological elements,including the average values of temperature,maximum temperature,minimum temperature,degree of comfort,precipitation,vapor pressure,low cloud cover,change of vapor pressure,and change of wind speed,were all greater than 0.8286,in which one of the relationship between the incidence of respiratory diseases and the maximum temperature is as high as 0.9670.Statistical tests showed RRα=0.05 and FFα=0.05.Conclusions：The incidence of respiratory diseases was closely correlated to meteorological factors,such as air temperature,vapor pressure,precipitation,wind speed,etc.To a certain extent,this conclusion confirmed the scientificity and objectivity of the theory of five evolutive phases and six climatic factors（Wu Yun Liu Qi,五运六气） in Huang Di Nei Jing（黄帝内经,The Yellow Emperor＇s Canon of Internal Medicine）.

文摘Objective To identify the representative attributes of the five elements of a person with a qualitative methodology and provide the basis for the clinical diagnosis and treatment of“people with the five elements in traditional Chinese medicine(TCM).”Methods Data collected from the literature review,two sessions of brainstorming of experts with related experience in“people with the five elements in TCM”from October 2020 to December 2020,and six rounds of in-depth interviews with 30 participants who had various attributes of the five elements from March 2021 to October 2021 were analyzed.Triangulation was used in this study,and theming and synthesizing were used to analyze the data.Results A total of 31 experts and 30 interviewees participated in this study.The median age of the experts and interviewees were 48.0 and 38.5 years,respectively;51.66%and 54.8%of experts and interviewees,respectively,were men.The descriptors of facial diagrams of“people with the five elements in TCM”were complexion,shape,distribution state of facial bones,convergence trend of facial muscles,and facial expression.A theoretical model of“people with the five elements in TCM”was shaped based on these findings.Conclusion The study suggests a possibility for bridging the gap between personality and bodily state,identifying an avenue for personality research from the perspective of TCM.
文摘Investigating the role of Big Five personality traits in relation to various health outcomes has been extensively studied. The impact of “Big Five” on physical health is here explored for older Europeans with a focus on examining age groups differences. The study sample included 378,500 respondents derived from the seventh data wave of Survey of Health, Aging and Retirement in Europe (SHARE). The physical health status of older Europeans was estimated by constructing an index considering the combined effect of well-established health indicators such as the number of chronic diseases, mobility limitations, limitations with basic and instrumental activities of daily living, and self-perceived health. This index was used for an overall physical health assessment, for which the higher the score for an individual, the worst health level. Then, through a dichotomization process applied to the retrieved Principal Component Analysis scores, a two-group discrimination (good or bad health status) of SHARE participants was obtained as regards their physical health condition, allowing for further con-structing logistic regression models to assess the predictive significance of “Big Five” and their protective role for physical health. Results showed that neuroti-cism was the most significant predictor of physical health for all age groups un-der consideration, while extraversion, agreeableness and openness were not found to significantly affect the self-reported physical health levels of midlife adults aged 50 up to 64. Older adults aged 65 up to 79 were more prone to open-ness, whereas the oldest old individuals aged 80 up to 105 were mainly affected by openness and conscientiousness. .

文摘OBJECTIVE: To observe the clinical effects of the Lixujieyu recipe combined with Five Elements music therapy on chronic fatigue syndrome(CFS) identified as the symptom patterns of liver stagnation and spleen deficiency in terms of Traditional Chinese Medicine.METHODS: Patients with CFS were randomly divided into treatment group 1(Lixujieyu recipe combined with Gong-Tune, n = 15); treatment group 2(Lixujieyu recipe combined with Jiao-Tune, n = 15);treatment group 3(Lixujieyu recipe combined with Yu-Tune, n = 15); treatment group 4(Lixujieyu recipe combined with Shang-Tune, n = 15); treatment group 5(Lixujieyu recipe combined with Zhi-Tune,n = 15); and the control group(Lixujieyu recipe alone, n = 15). Chinese medicine was given twice daily, and music was listened to for 45 minutes daily, 5 days a week. All patients were treated for4 weeks. Patients were assessed via the Fatigue Scale, the Hamilton Depression Rating Scale, and the Hamilton Anxiety Rating Scale before and after treatment.RESULTS: Treatment groups 1 and 2 had better effects on relieving the symptoms of physical fatigue related to anxiety and depression than the control group(P < 0.05).CONCLUSION: Lixujieyu recipe combined with Gong-Tune or Jiao-Tune significantly relieved the symptoms of CFS.
