To investigate fecal continence in patients with irritable bowel syndrome (IBS), studies were performed in 43 patients with IBS and 20 healthy subjects. Anorectal pressure was measured with BioLAB monitor of digestive tract and anorectal catheter with solid state manometric transducers. The results were analyzed by computation programs of American Sandhill Company. The sensation of defecation volume (DSV),sensation of defecation urgent volume (DUSV) and maximal tolerable volume (MTV) in the patients with diarrhea predominant type IBS (Dp-IBS) were significantly lower than healthy subjects (P

In this paper, a systematic architecture of medical data mining based on computer was provided for epidemiological analysis. Complications in diabetes mellitus were used as the cases under discussions on redundancy elimination, normalized storage, knowledge induction and visual expression of medical data. 3022 pieces of census records from Tianjin General Hospital were researched to find the solution of quantitative mining from qualitative data and knowledge discovery. From the qualitative data mining of 43 kinds of complications in diabetes mellitus, we found 18 knowledge rules with significant statistical meaning on concurrency relation, e. g. hyperlipoidemia, coronary disease, hypertension and cerebrovascular disease. And knowledge tree was noted to be an effective visual expression method for showing the rules generated from the above system. Medical analysis system based on data mining and knowledge discovery could generate effective knowledge rules from medical record database, which was found to be especially useful for epidemiological analysis and national health survey. So how to cooperate with community medical care and hospital information system in the near future is practically significant.

Objective:To explore the relationships among perceived social constraints, social participation, as well as anxiety and depression in first stroke patients, and to further analyze the mediating effect of social participation on these variables.Methods:A total of 216 first stroke patients in the Department of Neurology of Affiliated Hospital of Qingdao University from April to December 2020 were recruited by convenience sampling and investigated by general information questionnaire, Social Constraints Scale (SCS), Chinese version of Impact on Participation and Autonomy Questionaire (IPA-C) and Hospital Anxiety and Depression Scale (HADS).Results:The total score of SCS, IPA-C, depression and anxiety were 33.49 ± 6.81, 43.42 ± 9.62, 8.05 ± 4.15 and 8.61 ± 2.59. Social constraints were positively correlated with social participation as well as anxiety ( r=0.644, 0.383, both P<0.05). Social constraints were positively correlated with social participation as well as depression ( r=0.482, 0.371, both P<0.05). The quality of social participation partially mediated the relationship between social constraints and anxiety (intermediary effect was 0.119), and also partially mediated the relationship between social constraints and depression (intermediary effect was 0.270). Conclusions:First stroke patients experience high level of social constraints, low quality of social participation and severe anxiety and depression. Social constraints can affect anxiety and depression through social participation. Medical staff should build a good environment to meet the needs of stroke patients of social participation, help patients to establish a correct psychological coping style, reduce patients' avoidance of social participation due to perceived constraints and exclusion, and thus promote the mental health of patients.

Background::Dilated cardiomyopathy (DCM) has a high mortality rate and is the most common indication for heart transplantation. Our study sought to develop a multiparametric nomogram to assess individualized all-cause mortality or heart transplantation (ACM/HTx) risk in DCM patients.Methods::The present study is a retrospective cohort study. The demographic, clinical, blood test, and cardiac magnetic resonance imaging (CMRI) data of DCM patients in the tertiary center (Fuwai Hospital) were collected. The primary endpoint was ACM/HTx. The least absolute shrinkage and selection operator (LASSO) Cox regression model was applied for variable selection. Multivariable Cox regression was used to develop a nomogram. The concordance index (C-index), area under the receiver operating characteristic curve (AUC), calibration curve, and decision curve analysis (DCA) were used to evaluate the performance of the nomogram.Results::A total of 218 patients were included in the present study. They were randomly divided into a training cohort and a validation cohort. The nomogram was established based on eight variables, including mid-wall late gadolinium enhancement, systolic blood pressure, diastolic blood pressure, left ventricular ejection fraction, left ventricular end-diastolic diameter, left ventricular end-diastolic volume index, free triiodothyronine, and N-terminal pro-B type natriuretic peptide. The AUCs regarding 1-year, 3-year, and 5-year ACM/HTx events were 0.859, 0.831, and 0.840 in the training cohort and 0.770, 0.789, and 0.819 in the validation cohort, respectively. The calibration curve and DCA showed good accuracy and clinical utility of the nomogram.Conclusions::We established and validated a circulating biomarker- and CMRI-based nomogram that could provide a personalized prediction of ACM/HTx for DCM patients, which might help risk stratification and decision-making in clinical practice.

Objective:To develop the Health Promotion Behavior Intention Questionnaire for enterostomy patients and test its reliability and validity.Method:Based on the theory of planned behavior, the first draft of the questionnaire was formed through literature review, group discussion, correspondence with Delphi experts and pre-test. The convenient sampling method was used to select 419 patients with enterostomy who visited Stoma Outpatient Department of the Affiliated Hospital of Qingdao University from December 2020 to June 2021 to conduct a questionnaire survey. Item analysis and reliability and validity tests were carried out on the questionnaires.Results:The Health Promotion Behavior Intention Questionnaire for enterostomy patients included 15 items. Exploratory factor analysis extracted four common factors, namely, attitude, subjective norm, perceived behavioral control and behavioral intention. The cumulative variance contribution rate was 83.166%. The content validity index of item level was 0.875-1.000 and the content validity index of questionnaire level was 0.983. The Cronbach's α coefficient of the total questionnaire was 0.921 and the retest reliability coefficient was 0.848.Conclusions:The Health Promotion Behavior Intention Questionnaire for enterostomy patients has good reliability and validity and it can be used as a tool to evaluate the health promotion behavior intention of patients with enterostomy.

Objective:To explore the construction of evaluation criteria for long-term care ability of the elderly suitable for China's national conditions.Methods:The evaluation criteria were initially established through literature research and field semi-structured interviews. Through the Delphi method, 15 experts were consulted and the evaluation criteria for the long-term care ability of the elderly were finally established.Results:The effective rate of the two rounds of expert consultation questionnaires was 100%, and the expert authority coefficients were 0.91 and 0.92 respectively. The evaluation criteria for long-term care ability of the elderly were established, including two first-level indicators of self-care ability and disease severity, four second-level indicators of abilities of daily living, mental state and social participation, perception and communication, and disease severity, as well as 39 third-level indicators including recumbent status, cognitive function, level of consciousness, illness and so on.Conclusions:The evaluation criteria for long-term care ability of the elderly are scientific and reliable, which can provide a reference for the classification of long-term care services for the disabled elderly in China.

Objective:To observe the expression of noggin mRNA in the hippocampus of rats with chronic cerebral hypoperfusion, and explore the effect of electroacupuncture (EA) at the " baihui" and " dazhui" acupoints on their learning and memory and on hippocampal neurogenesis.Methods:In total, 120 Sprague-Dawley rats had cerebral hypoperfusion induced by permanent bilateral ligation of the common carotid artery. The 104 successfully induced were divided at random into a model group and an EA group, each of 52. The EA group was given EA on the baihui and dazhui acupoints for 20 minutes daily for seven days followed by a two-day break. The output current was 1mA at 15Hz. No special treatment was given to the model group. After one, two, four and six weeks of treatment, 6 rats were given BrdU injections to observe the proliferation and differentiation of neural stem cells. Learning and memory were assessed using the Morris Water Maze. The expression of noggin mRNA and neurogenesis in the dentate gyrus of the hippocampus were measured using reverse-transcription polymerase chain reactions and immunohistochemistry.Results:After one, two and five weeks of intervention, the average learning and memory ability of the EA group were significantly better than those of the control group. The average expression of noggin mRNA was significantly higher in the EA group than in the model group at the same time points. Compared with the model group, there were more BrdU-positive cells in the hippocampal dentate gyrus in the EA group, and the number decreased with the prolongation of ischemia. Pearson correlation analysis showed that the levels of noggin mRNA in the hippocampus of both groups were positively correlated with their number of BrdU-positive cells. The correlation was stronger in the EA group than in the model group.Conclusions:Electroacupuncture can promote hippocampal neurogenesis in rats with chronic cerebral hypoperfusion by regulating the expression of hippocampal noggin mRNA, thereby improving their spatial learning and memory ability.

Objective:To explore the relationship between lipid metabolism molecules in plasma and carotid atherosclerotic plaques,traditional cardiovascular risk factors and possible dietary related factors.Methods:Firstly,among 1 312 community people from those who participated in a 10-year follow-up study of subclinical atherosclerosis cohort in Shijingshan District,Beijing,85 individuals with 2 or more carotid soft plaques or mixed plaques and 89 healthy individuals without plaques were selected according to the inclusive and the exclusive criteria(＜70 years,not having clinical cardiovascular disease and other diseases,etc.).Secondly,10 cases and 10 controls were randomly selected in the above 85 and 89 individuals respectively.Carotid plaques were detected using GE Vivid i Ultrasound Machine with 8L de-tector.Lipid metabolism molecules were detected by high performance liquid chromatography-mass spec-trometry.The detection indexes included 113 lipid metabolism molecules.Traditional cardiovascular risk factors were collected by unified standard questionnaires,and dietary related factors were collected by main dietary frequency and weight scale.The difference of lipid metabolism molecules between the case group and the control group was analyzed by Wilcoxin rank test.In the control group,the Spearman cor-relation method was used to analyze the correlation between statistically significant lipid metabolism molecules and traditional cardiovascular risk factors and dietary factors.Results:Among the 113 lipid metabolism molecules,53 lipid metabolism molecules were detected.C24∶0 sphingomyelin(SM),C22∶0/C24∶0 ceramide molecules,C18∶0 phosphoethanolamine(PE)molecules,and C18∶0/C18∶2(Cis)phosphatidylcholine(PC)were significantly higher in the carotid atherosclerotic plaque group than in the control group.The correlation analysis showed that C24∶0 SM was significantly positively correlated with low density lipoprotein cholesterol(LDL-C,r=0.636,P＜0.05),C18∶2(Cis)PC(DLPC)was sig-nificantly positively correlated with systolic pressure(r=0.733,P＜0.05),C18∶0 PE was significantly positively correlated with high sensitivity C-response protein(r=0.782,P＜0.01),C22∶0,C24∶0 ce-ramide and C18∶0 PE were negatively correlated with vegetable intake(r=-0.679,P＜0.05;r=-0.711,P＜0.05;r=-0.808,P＜0.01),C24∶0 ceramide was also negatively correlated with beans food intake(r=-0.736,P＜0.05)in the control group.Conclusion:The increase of plasma C24∶0 SM,C22∶0,C24∶0 ceramide,C18∶0PE,C18∶2(Cis)PC(DLPC),C18∶0PC(DSPC)may be new risk factors for human atherosclerotic plaques.These molecules may be related to blood lipid,blood pres-sure or inflammatory level and the intake of vegetables and soy products,but the nature of the association needs to be verified in a larger sample population.

ObjectiveTo investigate the effect and mechanism of Shenling Baizhusan on the treatment of oligoasthenospermia with hyperuricemia （HUA）. MethodThirty-two male Kunming （KM） mice were randomly divided into blank group （n=6）， model group （n=6）， high-dose Shenling Baizhusan group （n=7）， low-dose Shenling Baizhusan group （n=7）， and febuxostat group （n=6）. Except for the blank group， all other groups received intraperitoneal injection of potassium oxazinate suspension （600 mg·kg^-1） for 7 days. After modeling， the high-dose Shenling Baizhusan group and the low-dose Shenling Baizhusan group were orally administered with 20.14 g·kg^-1 and 10.07 g·kg^-1 of Shenling Baizhusan， respectively. The Febuxostat group was orally administered with 0.25 g·kg^-1 of Febuxostat， while the blank group and model group were orally administered with the same volume of physiological saline. Oral administration was performed once a day for 14 consecutive days， after which samples were collected. Biochemical methods were used to measure serum uric acid （UA）， superoxide dismutase （SOD） and malondialdehyde （MDA） in testicular tissue. Hematoxylin-eosin （HE） staining was used to observe the histopathological changes in testicular tissue and evaluate the spermatogenesis function. Automated sperm analyzer was used to measure sperm density and motility. Single-cell gel electrophoresis （SCGE） was used to assess sperm DNA integrity. Terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling （TUNEL） was used to detect testicular cell apoptosis rate. Western blot analysis was performed to measure the protein expression levels of Kelch-like ECH-associated protein 1 （Keap1）， nuclear factor E₂-related factor 2 （Nrf2）， heme oxygenase-1 （HO-1）， B-cell lymphoma-2 （Bcl-2）， Bcl-2-associated X protein （Bax）， and Caspase-3 in testicular tissue. Real-time polymerase chain reaction （PCR） was conducted to evaluate the mRNA expression levels of Keap1， Nrf2， and HO-1 in testicular tissue. ResultCompared with the blank group， the model group showed elevated serum UA level （P<0.01）， decreased testicular spermatogenesis function， sperm density， and motility （P<0.01）， and increased sperm trailing rate and testicular cell apoptosis rate （P<0.01）. Compared with the model group， the high-dose Shenling Baizhusan group showed significant improvements in the above-mentioned indicators （P<0.05， P<0.01）. Additionally， the expression levels of Keap1， Bax， and Caspase-3 in testicular tissue were reduced， while the expression levels of Nrf2， HO-1， and Bcl-2 increased （P<0.05， P<0.01）. The mRNA level of Keap1 decreased （P<0.05， P<0.01）， while the mRNA levels of Nrf2 and HO-1 increased （P<0.05， P<0.01）. ConclusionShenling Baizhusan can significantly improve HUA oligoasthenospermia， and its mechanism may be related to the Nrf2/antioxidant response element （ARE） signaling pathway.
