Research purpose:This study implemented somatosensory music therapy on patients with depressive disorders,and explored the effects of somatosensory music therapy on the degree of depression,positive and negative emotions,intuitive stress and autonomic nervous function of patients.Research method:We collected 66 patients diagnosed with depression from the Department of Psychological Medicine of Henan Provincial People’s Hospital,and divided them into a control group and an intervention group according to the random number table,with 33 people in each group.The control group received routine psychiatric treatment and nursing.On the basis of the control group,the intervention group received somatosensory music therapy 3 times a week,30 min each time,for 4 consecutive weeks.The Hamilton Depression Scale,Positive and Negative Emotion Scale,Perceived Stress Scale,and Heart Rate Variability Index were collected and analyzed at baseline(T0),2 weeks after treatment(T1)and 4 weeks after treatment(T2).Research results:After 4 weeks of treatment,the HAMD scores of the two groups decreased to varying degrees,and the difference between the groups was statistically significant(p<0.05).After 4 weeks of treatment,the scores of positive emotions in both groups increased to varying degrees,and the scores of negative emotions increased to varying degrees.The scores decreased to varying degrees,and there were statistically significant differences between the positive and negative emotion groups(p<0.05).After 4 weeks of treatment,the CPSS scores of the two groups decreased to varying degrees,and the difference between the two groups was statistically significant(p<0.05).Analyzing the main effect of intervention factors alone,after 4 weeks of treatment,SDNN and RMSSD indexes all increased to varying degrees,and the degree of increase in the intervention group was greater than that in the control group,and the difference between the groups was statistically significant(p<0.05).Research conclusion:assisting somatosensory music therapy for patients with depressive disorders can improve depressive symptoms,increase positive emotions,reduce negative emotions,and reduce perceived stress.These are beneficial to restore the balance of autonomic nervous system,and are effective for the treatment of depression.

Risk factors for secondary infection after liver failure and effect of comprehensive nursing intervention

BACKGROUND In patients with liver failure(LF),the high rate of secondary infections,which are associated with poor prognosis,highlights the clinical significance of understanding the underlying risk factors and implementing targeted intervention programs.AIM To investigate risk factors for secondary infections in patients with LF and evaluate the effectiveness of comprehensive nursing interventions.METHODS This retrospective study included 64 patients with LF,including 32 with and 32 without secondary infections.A questionnaire was used to collect data on age;laboratory parameters,including total and direct bilirubin,prothrombin time,blood ammonia,and other biochemical parameters;invasive procedures;and complications.Patients with secondary infections received comprehensive nursing intervention in addition to routine nursing care,whereas those without secondary infections received only routine nursing care to compare the effect of nursing intervention on outcomes.RESULTS The infection rate,which was not associated with age or complications,was significantly associated with biochemical parameters and invasive procedures(P<0.05).The infection rate was 61.6%in patients who had undergone invasive procedures and 32.1%in those who had not undergone invasive procedures during the hospital stay.The infection rate was also significantly associated with the type of LF(P<0.05),with the lowest rate observed in patients with acute LF and the highest rate observed in those with subacute LF.The nursing satisfaction rate was 58.3%in the uninfected group and 91.7%in the infected group,indicating significantly higher satisfaction in the infected group(P<0.05).CONCLUSION In patients with LF,the rate of secondary infections was high and associated with biochemical parameters and type of LF.Comprehensive nursing intervention can improve patient satisfaction.

The Impact and Intervention of Handheld Tai Chi Water-Resistance Fitness Ball on Middle-Aged and Elderly Patients with Parkinson’s Disease

Through the use of a survey and statistical methods, this study explores the effects and interventions of handheld Tai Chi water resistance fitness balls on the elderly with Parkinson’s disease. Firstly, a questionnaire on exercise compliance for patients with Parkinson’s disease was developed, and its reliability and validity were tested. Then, a survey was conducted to investigate the current status of exercise compliance among Parkinson’s disease patients, including general information, scoring status, and single and multiple factor analyses of influencing factors [1]. The results of the study show that through qualitative research, the dimensions and item pools of the questionnaire were initially constructed, and the reliability analysis of the questionnaire was conducted through Delphi expert consultation, with favorable results in terms of its reliability and validity [2]. Regarding the current status of exercise compliance among Parkinson’s disease patients, the study found that the level of exercise compliance needs improvement, and there are significant differences in exercise compliance levels among patients under different circumstances. Finally, the research results were discussed and conclusions were drawn. The innovation of this study lies in the development of a questionnaire on exercise compliance for patients with Parkinson’s disease and the preliminary qualitative research and Delphi expert consultation conducted on it, providing new ideas and methods for the study of exercise compliance. However, the study also has limitations as it did not examine the effects of other interventions on Parkinson’s disease, so further research should be conducted [3].

BACKGROUND： Phycocyanin can relieve decrease of mitochondrial membrane potential through reducing production of active oxygen so as to protect neurons after hypoxia/reoxygenation. OBJECTIVE： To observe the effect of phycocyanin on activity of PC12 cells and mitochondrial membrane potential after hypoxia/reoxygenation. DESIGN： Randomized controlled study SETTING ： Cerebrovascular Disease Institute of Affiliated Hospital, Medical College of Qingdao University MATERIALS： The experiment was carried out at the Key Laboratory of Prevention and Cure for cerebropathia in Shandong Province from October to December 2005. PC12 cells, rat chromaffin tumor cells, were provided by Storage Center of Wuhan University; phycocyanin was provided by Ocean Institute of Academia Sinica; Thiazoyl blue tetrazolium bromide （MTT） and rhodamine 123 were purchased from Sigma Company, USA; RPMI-1640 medium, fetal bovine serum and equine serum were purchased from Gibco Company, USA. METHODS： ① Culture of PC12 cells： PC12 cells were put into RPMI-1640 medium which contained 100 g/L heat inactivation equine serum and 0.05 volume fraction of fetal bovine serum and incubated in CO2 incubator at 37℃. Number of cells was regulated to 4 × 10^5 L 1, and cells were inoculated at 96-well culture plate. The final volume was 100μL. ② Model establishing and grouping： Cultured PC12 cells were randomly divided into three groups： phycocyanin group, model control group and non-hypoxia group. At 24 hours before hypoxia, culture solution in phycocyanin group was added with phycocyanin so as to make sure the final concentration of 3 g/L , but cells in model control group did not add with phycocyanin. Cells in non-hypoxia group were also randomly divided into adding phycocyanin group （the final concentration of 3 g/L） and non-adding phycocyanin group. Cells in model control group and phycocyanin group were cultured with hypoxia for 1 hour and reoxygenation for 1, 2 and 3 hours; meanwhile, cells in non-hypoxia group were cultured with oxygen and were measured at 1 hour after hypoxia/reoxygenation. ③ Detecting items： At 1, 2 and 3 hours after reoxygenation, absorbance （A value） of PC12 cells was measured with MTT technique so as to observe activity and quantity of cells. Fluorescence intensity of PC12 cells marked by rhodamine 123 was measured with confocal microscope in order to observe changes of mitochondrial membrane potential. MAEN OUTCOME MEASURES： Comparisons between quantity and activity of PC12 cells and mitochondria membrane potential at 1, 2 and 3 hours after reoxygenation. RESULTS： ① Effect of phycocyanin on quantity and activity of PC12 cells： A value was 0.924±0.027 in adding phycocyanin group and 0.924±0.033 in non-adding phycocyanin group. A value was lower in model control group and phycocyanin group than that in non-hypoxia group at 1, 2 and 3 hours after reoxygenation （0.817±0.053, 0.838±0.037, 0.875±0.029; 0.842±0.029, 0.872±0.025, 0.906±0.023, P 〈 0.05）. A value was higher in phycocyanin group than that in model control group at 1, 2 and 3 after culture （P 〈 0.05）. With culture time being longer, A value was increased gradually in phycocyanin group and model control group after reoxygenation （P 〈 0.05）. ~ Effect of phycocyanin on mitochondrial membrane potential of PC12 cells： Fluorescence intensity was 2.967±0.253 in adding phycocyanin group and 2.962±0.294 in non-adding phycocyanin group. Fluorescence intensity was lower in model control group and phycocyanin group than that in non-hypoxia group at 1, 2 and 3 hours after hypoxia/reoxygenation （1.899±0.397, 2.119±0.414, 2.287±0.402; 2.191±0.377, 2.264±0.359, 2.436±0.471, P 〈 0.05）; but it was higher in phycocyanin group than that in model control group at 1, 2 and 3 after reoxygenation （P 〈 0.05）. With culture time being longer, fluorescence intensity was increased gradually in phycocyanin group and model control group after reoxygenation （P 〈 0.05）. CONCLUSION： Phycocyanin and reoxygenation can protect PC12 cells after hypoxia injury through increasing mitochondrial membrane potential and cellular activity, and the effect is improved gradually with prolonging time of reoxygenation.

Interventional effect of hirudin on the expression of microtubule-associated protein 2 in peripheral tissue of hematom of model rats with acute intracerebral hemorrhage

BACKGROUND： It is suspected that dissociation, destruction or synthetic disorder of microtubule-associated protein 2 （MAP-2） may participate in secondary injury of intracerebral hemorrhage （ICH）, and the reason may be related to thrombin in high concentration after ICH; therefore, the mechanism should be studied further. OBJECTIVE： To explore the effect of hirudin on expression of MAP-2 in peripheral tissue of hematom after ICH and changes of water content in brain tissue and analyze pathogenesis of thrombin in secondary injury after ICH. DESIGN ： Completely randomized grouping design and controlled animal study SEn-ING ： Department of Neurology, the First Affiliated Hospital of Jilin University MATERIALS ： The experiment was carried out in the Neurological Laboratory of the First Affiliated Hospital of Jilin University from April 2003 to April 2004. A number of 80 healthy Wistar rats, of both genders, aged 3-4 months, weighing 250-350 g, were randomly divided into 8 groups： normal control group, 6-hour ICH group, 1-day ICH group, 2-day ICH group, 3-day ICH group, 7-day ICH group, 3-day hirudin group and 7-day hirudin group with 10 in each group. Five rats from each group were selected to measure their water content, and the others were undertaken immunohistochemical stain. Hirudin was produced by Sigma Company, USA, and MAP-2 rabbit-rat polyclonal antibody was provided by Fuzhou Maixin Biotechnology Company Limited. METHODS： ① Model establishing and grouping intervention： Rats in simple ICH group were collected their blood from tails and then inserted with 50 μL non-anticoagulant auto-arterial blood into the cauda of the putamen in right brain within 5 minutes. Rats in hirudin groups were inserted with 10 U hirudin （which was diluted with saline to 20 μL） into local hematom regions within 5 minutes, and the needle was pulled out after 10 minutes. Rats in normal control group were untouched. ② Water content in peripheral tissue of hematom： Based on the ratio between dry weight and wet weight, brain tissue at bleeding side and in right frontal lobe was selected to measure dry and wet weights so as to calculate the water content [（wet weight - dry weight） /wet weight] × 100%.③ Positive expression of MAP-2： Based on immunohistochemical stain, positive MAP-2 cells were regarded as neurons and they were buffy morphological. Positive rate of MAP-2 was calculated, i.e., percentage of positive cells in each sight to total cells in all sights. ④ Statistical analysis： Data among groups were compared with one-way analysis of variance, averages were compared with SNK-q test by each other, and relation between water content and MAP-2 was analyzed with linear regression technique. MAIN OUTCOME MEASURES： Changes of water content and MAP-2 expression in peripheral tissue of hematorn at various time points after ICH and intervention of hirudin. RESULTS： All 80 rats were involved in the final analysis. ①Water content： Water content was increased at day 1, reached peak at day 3 and decreased at day 7. It was （72.31±0.32）%, （77.42±0.53）%, （78.44±0.28）%, （74.10±0.13）%, （74.85±0.51）% and （70.07±0.36）%, respectively in 1-day, 2-day, 3-day and 7-day ICH groups and 3-day and 7-day hirudin groups, which was higher than that in normal control group （63.85±0.41, q=-4.684 3 to -7.262 0, P〈 0.05）; that in 2-day and 3-day ICH groups was higher than that in 7-day ICH group （q=-3.053 4, -3.727 0, P 〈 0.05）; and that in 3-day and 7-day ICH groups was higher than that in hirudin groups at the same time points （q=-2.965 6, -2.726 4, P 〈 0.05）. ②Positive expression of MAP-2： Positive expression of MAP-2 was decreased at 6 hours after ICH, reached the lowest value at day 3 and increased at day 7. Positive rate was （78.60±0.42）%, （60.56±0.74）%, （44.60±0.26）%, （25.45±0.85）%, （32.55±0.64）%, （37.69＋0.76）%, （41.75±0.68）%, respectively in 6-hour, 1-day, 2-day, 3-day and 7-day ICH groups and 3-day and 7-day hirudin groups, which was lower than that in normal control group [（96.50±0.33）%, q= -3.074 5 to -8.128 5, P 〈 0.05]. In addition, positive cells of MAP-2 disappeared plentifully at 3-7 days after ICH, stain of positive cells were light, and only stain of plasma was positive. That in 3-day and 7-day hirudin groups was higher than that in ICH groups at the same time points （q= -3.391 8, -2.967 9, P 〈 0.05）. Moreover, positive cells of MAP-2 was formed slightly but deeply stained. ③ Results of linear regression： Water content was negatively related to MAP-2 changes at 7 days after ICH （r= -0.894 9, P〈 0.01）, i.e., water content was increased with decrease of MAP-2 expression. CONCLUSION ： The deterioration of MAP-2 may be involved in the pathogenesis of thrombin within the first week after ICH, and the local administration of hirudin can protect neurons.

Effect of intervention treatment from different stages on prognosis in children with central coordination disturbance

BACKGROUND： Central coordination disturbance is regarded as the early-stage symptom of brain injury-induced cerebral palsy. This disease manifests itself as motor disorder, abnormal attitudinal reflex and muscular tension. Early intervention may improve its prognosis. OBJECTIVE： To observe the effects of intervention treatment from different stages on the prognosis of central coordination disturbance following brain injury in children patients. DESIGN： A contrast observation experiment SETTING： Department of Neurology and Rehabilitation, Urumqi Children＇s Hospital PARTICIPANTS ： Totally 151 children who were diagnosed as central coordination disturbance from January 2002 to December 2003 in the Department of Neurology and Rehabilitation of Urumqi Children＇s Hospital were recruited. All the children patients, including 101 male and 50 female, aged from 3 months to 1 year old, met the diagnosis criteria of central coordination disturbance from Vojta. They were divided into slight, moderate and severe abnormity according to Vojta attitudinal reflex. All 151 patients were divided into 2 groups according to their age at diagnosis： 3-6 months old group （n=74）, 62 severe, 10 moderate and 2 slight; 7-12 months old group （n=77）, 66 severe, 7 moderate and 4 slight. All the relatives of children patients were informed of the experiment. METHODS： ① Both groups received physical training （PT） as the main treatment; Hand training was given if necessary. All of the patients received additional hyperbaric oxygen therapy, bioelectric therapy, scalp acupuncture, drug treatment and family training. The importance of integration of hospital and family based rehabilitation was stressed. Those who did not catch up with the normal development or had abnormal reflexes continued to receive treatment. ② Around the age of 2 years old, all children did a final evaluation using Bayley Scales of Infant Development （BSID）. Mental development index （MDI） and physical development index （PDI） were taken as evaluative criteria. Children with scores 80 and above on MDI and PDI were considered to have normal motor and mental development; 79 and below were considered delayers. The Diagnostic Criteria of Cerebral Palsy and Infantecondary School Social Adaptation Scale were used in the final evaluation[scores ≤5 was extremely severe （extremely severe cerebral palsy）, 6 was severe（severe cerebral palsy）, 7 was moderate（moderate cerebral palsy）, 8 was slight（slight cerebral palsy）, 9 was borderline（slight cerebral palsy）, 10 was normal, 11 was above average, 12 was excellent and ≥13 was extremely excellent]. ③ Final evaluative results of 2 groups were compared. And u test was used for the comparison of Bayley development index and Chi-square test for the comparison of normalization rate. MAIN OUTCOME MEASURES： BSID MDI and PDI as well as the normalization rate of motor function and mental behavior of children patients at 2 years old. RESULTS： Totally 151 children patients entered the stage of result analysis. ①Two groups of children patients were given integrated rehabilitation therapy , and evaluated at 2 years old . The 3-6 months old group had higher MDI and PDI than the 7-12 months old group （91.81＋19.99 vs 71.93＋18.98;91.55＋23.61 vs 68.95＋23.51, u=6.265,5.894,P 〈 0.01 ）.②After being given integrated rehabilitation therapy, children patients of 3-6 months old group had significantly higher normalization rate of motor function and mental behavior than 7-12 months old group （73% ,27%,X2=29.723 9,P 〈 0.01 ）. ③Six slight and 17 moderate central coordination disturbance children of 2 groups all completely recovered; After intervention treatment, among 128 severe central coordination disturbance children, 52 recovered and 76 were still abnormal, in which, 43 slight cerebral palsy, 18 moderate cerebral palsy, 5 severe cerebral palsy and 10 extremely severe cerebral palsy. CONCLUSION： To perform integrated intervention treatment before 6 months old can better improve and promote mental and physical development levels of children patients with central coordination disturbance after brain injury than 6 months later.

Exposure to Hyaluronan and Radon-Containing Water during the Treatment of Periodontal Pockets

Hyaluronic acid (HA) preparations have emerged as pivotal components in contemporary dentistry, gaining widespread recognition for their multifaceted roles in various biological functions. Extensive literature underscores the significance of HA in maintaining tissue water balance, fostering cell proliferation, promoting rapid cell migration, influencing cell differentiation during organism development, and facilitating tissue regeneration. Notably, HA’s interactions with cell surface receptors contribute to the viscosity of synovial fluid, activate the immune system, and enhance cartilage elasticity. Beyond these established functions, HA has also been investigated for its potential involvement in determining and studying the hormetic effects of radon water, adding a novel dimension to its applications in dental research. A thorough exploration of existing studies reveals a nuanced understanding of how HA interventions impact the outcomes of dental procedures. The comprehensive scope of these investigations allows for a more accurate assessment of the potential effectiveness of specific interventions and provides valuable insights into post-procedural prognoses for individual patients. This synthesis of literature serves as the foundation for elucidating the intricate interplay between HA, radon exposure, and their relevance in modern dental practices.
