ABSTRACT
Objective@#To explore the relationship between handgrip strength (HGS) and pulmonary function (PF) in college students with sedentary lifestyle, so as to provide a reference for taking HGS as an essential factor of PF.@*Methods@#In March 1-5, 2023, a total of 44 college students were recruited and were divided into the sedentary group (22) and exercise group (22) according to the International Physical Activity Questionaire (IPAQ), with 22 students in each group. Independent sample t-test was used to compare the indexes between groups, pearson correlation coefficient was used to determine the correlation between HGS and PF. Multiple linear regression analysis was used to determine the predictive model of PF.@*Results@#There were statistical significance of the correlations between HGS and FVC, MEP, PEF, FEV1, FIVC, MIP, and PIF ( r=0.79, 0.47, 0.44, 0.60, 0.72, 0.53 , 0.49, P <0.01). When gender, physical activity, age, height, weight, and HGS were included as predictors in the regression model, height and HGS had significant effects on FVC ( R 2=0.75, F= 60.55 , P <0.01), weight and HGS had a good predictive effect on FIVC ( R 2=0.67, F=41.77, P <0.01).@*Conclusion@#HGS is significantly associated with PF in college students with sedentary lifestyle. Therefore, HGS can be used as an important indicator to predict the PF status of habitual sedentary college students.
ABSTRACT
Objective To examine the brain metabolic changes in WD patients receiving copper chelation by us?ing 1H-MRS. Method Thirty-nine patients with WD was randomly divided into four groups: non-brain type group (18 cases), brain type prior-treatment group and short-term treatment group (21 cases), long-term treatment group (20 cases) from short-term treatment group, and 20 healthy volunteers served as a control group. 1H-MRS and MRI were performed on patients on 1.5/MR/MRS system to detect these above-mentioned items before and after treatment. Result The mean of NAA/Cr was significantly lower in the left putamen and head of the caudate nucleus than in the left basal ganglion in the 39 patients with WD. The mean of NAA/Cr and Cho/Cr in the left putamen and basal ganglion was significantly lower in non-brain type group than in control group(P0.05). The mean of NAA/Cr and NAA/Cho in the left putamen and basal ganglion was much higher in long-term treatment group than in brain type group(P<0.01 or P<0.05). The mean of Cho/Cr in the left head of caudate nucleus were much higher after treatment compared with prior-treatment group(P<0.05). The mean of NAA/Cr in the left putamen, head of the left caudate nucleus and basal ganglion in all groups was negatively correlated with course of the disease. Conclusion There are significant differences in brain metabolism among different type of WD. The long-term but not short-term copper chelation significantly improves brain metabolism. NAA/Cr may be used as a non-invasive indicator to examine the efficacy of treatment.
ABSTRACT
Objective To explore the genetic mechanism of Yang-deficiency constitution by detecting genomic copy number variations (CNVs). Methods Thirty cases of Yang-deficiency constitution and 30 cases of balanced constitution were included according to the standards of Classification and Determination of Constitution in Traditional Chinese Medicine. DNA was extracted from white blood cells in peripheral blood. A genome-wide association study was conducted by using Affymetrix SNP 6.0 platform. CNVs of each sample were analyzed using PennyCNV software. The Yang-deficiency constitution-specific copy number variation regions (CNVRs) of each autosome were identified. CNVR-related genes and their annotations were searched at online Human Genome Browser. Results The mean number of CNVs in balanced constitution group was 12.63±3.39, ranging from 8 to 20. After stepwise elimination of two Yang-deficiency constitution subjects, the mean number of CNVs in Yang-deficiency constitution group was 15.04±8.95, ranging from 2 to 38. A total of 26 CNVRs were identified from 28 Yang-deficiency constitution subjects, including 19 duplicated CNVRs, 6 deleted CNVRs, and 1 mixed type CNVR. Most CNVRs were shared by a few Yang-deficiency constitution subjects, and only 7 CNVRs were shared by more than 5 Yang-deficiency constitution subjects. The functions of representative genes in Yang-deficiency constitution-specific CNVRs were related with extracellular and intracellular signal transduction, metabolic regulation, and immune response, etc. Conclusion Yang-deficiency constitution subjects have some specific genomic CNVs, which might result in Yang-deficiency constitution phenotypes by influencing the expression of genes associated with extracellular and intracellular signal transduction, material metabolism (energy metabolism), and immune response, etc.
ABSTRACT
[Abstrict] Objective To explore the effect of systemic family dynamics,egma minnen bardndom on the psychological traits,treatment efficacy of the first onset schizophrenia.Methods 53 schizophrenia patients with first onset were assessed by Self-rating Scale of Systemic Family Dynamics (SSFD),Egma Minnen Bardndom Uppforstran (EMBU),Neurotism Scale (Nf),Psychoticism (PSY),Paranoia Scale (Pa),Psychopathic Deviate Scale (Pd),Tolerance Scale(To) of MMPI-2,and lie Scale (L) was used to control assessment effectiveness.40 normal control cases were assessed by SSFD and EMBU.The scale scores between study group and control groupwere compared,and correlation and regression of study group were analyzed.Results Scores of family atmosphere,individuation,system logic of SSFD were higher in study group than those in control group (t=4.04,3.295,2.44,all P＜0.05),scores of emotional warmth and understand of EMBU in father and mother were lower in study group than those in control group (t=2.925,3.45,all P＜0.01),scores of refused and deny and punishment and stern of EMBU in father and mother were higher in study group than those in control group((t=4.715,4.971,4.331,4.067,all P＜0.01)).And correlation analysis showed that refused and deny of EMBU of father and mother,punishment and stern of EMBU of mother and PSY had significantly positive correlation(r=0.3378,0.4677,0.2895,all P＜0.05),refused and deny and punishment and stern of EMBU of father and mother and Pa had significantly negative correlation (r=-0.2913,-0.3254,-0.5003,-0.3242,all P＜0.05),punishment and stern and excessive interference of EMBU of father and Pd had significant positive correlation (r=0.3417,0.2958,all P＜0.05),PSY of MMPI-2 and treatment effect had significant negative correlation (r=-0.3194,P＜0.05).Regression analysis showed that psychoticism to forecast the poor treatment effect the rate was 10.2％,father and mother the refused and deny to forecast psychoticism high mark the rate respectively were 11.41％ and 21.87％,mother the severe punishment to forecast the psychoticism high mark the rate was 8.13％,Conclusion Father and mother the refused and deny,mother severe punishment have effects on psychological traits of the first onset schizophrenia,psychoticism of psychological traits has an affect on treatment efficacy,the psychoticism high mark presages the poor treatment efficacy.

Escherichia coli was the most common pathogen(isolated),the others were Enterococcus faecalis,Candida albicans,Enterobacter cloacae,et al.CONCLUSIONS The operation of indwelling catheter,continued times of indwelling catheter,improper application of antibiotics are the important risk factors of urinary tract infection.The infection rate could be decreased after taking(prevention) measures according to various related factors.
ABSTRACT
OBJECTIVE To investigate approaches to the prevention of sharps injuries. METHODS A retrospective questionnaire was performed for 193 nurses of a general hospital from the time of Jan 2004 to Jun 2005. RESULTS The questionnaires indicated that 46.1% nurses had suffered sharps injuries,with averaged of 1.6 times per person,of which 36.7% and 32.4% were caused respectively by syringe needles and glass wares.Opening ampules,disposal of used sharps,installing the syringe needles and transmitting sharp devices were the four major events in which sharps injuries might happen,accounted for 29.5%,22.3%,15.8% and 10.1%,respectively.It is also noted that 79.1% nurses suffering from the injury wore no gloves. CONCLUSIONS Occupational hazards of sharps injuries are threatening nurses.Certain prophylactic measures should be taken to control and prevent sharps injuries.
ABSTRACT
OBJECTIVE To discuss the management methods of sputum sample retained clinically based on the praxiology,and aim at improving the quality of the sputum retained. METHODS Through investigating the quality of sputum sample retained routinely from the department of internal medicine in a general hospital at the duration from Sep 2004 to Feb 2005,the intervention effect was evaluated by carrying out the measure of praxiology intervention. RESULTS The qualification rate was 23.7% for the sputum sample retained routinely from the hospital at the duration from Sep 2004 to Feb 2005,after carrying out the measure of praxiology intervention,the qualification rate was 30.1% at the duration from Apr 2005 to Aug 2005.Statistic data showed that there was no significant difference. CONCLUSIONS The quality of the sputum sample retained routinely is poor,and the measure of praxiology intervention failed to improve the quality of the sputum sample.Microscopy is the most important measure to ensure the quality of the sputum sample for the cytology test before cultivating the sample,and should be a routine test in hospital.The study on praxiology intervention will be further carried out in the future.
