Objective To translate the nursing time management scale(NTMS)into Chinese and test its reliability and validity,hence to provide a tool for evaluating the time management among nurses in China.Methods Authorised by the author on June 30th,2023,the English version of NTMS was translated into a Chinese version through forward translation,reverse translation,cross-cultural debugging and pre-test by using Brislin translation model.Between September 2023 and January 2024,a convenience sampling method was employed to select a total of 409 nurses as the test subjects from five hospitals of Grade IIA and above in Dongguan.Then the reliability and validity of the translated version of NTMS were tested.Results All 409 nurses completed the tests.The Chinese version of NTMS included three dimensions comprising 15 items:6 in nursing work planning and goal setting,3 in organisation of nursing work and 6 in coordination of nursing work.It was found that the mean scale content validity index(S-CVI/Ave)was 0.920,and the item-level CVI(I-CVI)ranged from 0.840 to 1.000.The overall Cronbach's α coefficient of the scale was 0.894,with 0.700 for the split-half reliability coefficient of and 0.942 for the retest reliability.The Cronbach's α coefficient of each of the 3 dimensions ranged from 0.781 to 0.901,with the split-half reliability coefficient from 0.823 to 0.870 and the retest reliability from 0.692 to 0.965.In the exploratory factor analysis,the KMO value was 0.904.The statistic test of Bartlett's sphericity was 3941.503(P<0.05),with the factor load range of each entry from 0.629 to 0.838.The cumulative variance contribution rate was 67.672%.Conclusion The translated Chinese version of the nursing time management scale demonstrates good reliability and validity.It can be applied as an effective evaluation tool in the nursing time management.

Objective To investigate the occurrence status quo and influencing factors of low muscle mass(LMM)among young and middle-aged health examination population.Methods The young and middle-aged people undergoing the body composition analysis in this hospital from January to December 2023 were selected as the study subjects.The general data,body composition indices and biochemical indicators were col-lected.The body composition analysis was performed by the bioelectrical impedance analysis(BIA).LMM was diagnosed based on the skeletal muscle index.The univariate and multivariate logistic regression were used to analyze the influencing factors of LMN occurrence in the young and middle-aged health examination population.The receiver operating characteristic(ROC)curve and the area under the curve(AUC)were em-ployed to evaluate the predictive value of each indicator.Results A total of 2 351 people undergoing the phys-ical examination were included,aged 18-49 years old,366(15.57％)cases of LMM were detected out.The skeletal muscle index,sex,age,age group distribution,body mass index(BMI),body fat percentage(BFP),body fat percentage grade,visceral fat area(VFA),AST/ALT,Hb,serum creatinine,blood uric acid,HbA1c,fasting blood glucose,TC,LDL-C,HDL-C,TG and triglyceride-glucose index(TyG)had statistical differences between the LMM group and normal group(P＜0.05).Multivariate logistic regression revealed that the sex(OR=2.606,95％CI:1.755-3.870),BMI(OR=0.579,95％CI:0.538-0.623),BFP(OR=5.885,95％CI:4.176-8.292)and VFA(OR=0.955,95％CI:0.944-0.967)were the influencing factors for the LMM oc-currence in the young and middle-aged people undergoing the physical examination(P＜0.001).The ROC a-nalysis showed the AUC values of the sex,BMI,BFP and VFA for predicting LMM were 0.580,0.821,0.636 and 0.715 respectively,in which the predictive value of BMI was highest.Conclusion The population of fe-male,low BMI,high BFP and low VFA maybe the high-risk groups for LMM.The health management for the above-mentioned groups needs to be strengthened.

Objective:To summarize and analyze the clinical features of patients with inflammatory bowel disease (IBD) accompanied by axial spondyloarthritis (ax-SpA) .Methods:A descriptive case series study was conducted. Consecutive IBD patients with ax-SpA admitted to Peking Union Medical College Hospital from January 2012 to December 2023 were enrolled, and the clinical data were collected and analyzed descriptively.Results:A total of 21 IBD patients with ax-SpA were enrolled, including 14 males (66.7%) and 7 females (33.3%). The median age at IBD diagnosis was 29 (24, 42) years. Among them, 10 had ulcerative colitis (UC) and 11 had Crohn's disease (CD). In 11 patients (52.4%), ax-SpA was diagnosed before IBD, while in 7 patients (33.3%), IBD was diagnosed before ax-SpA; the remaining 3 patients (14.3%) were diagnosed simultaneously. Thirteen patients (61.9%) had other extraintestinal manifestations, with 12 involving mucocutaneous manifestations. Nineteen patients including 9 UC and 10 CD were followed up for a median duration of 34 (12, 57) months. Among UC patients, 5 (55.6%) were escalated from conventional therapy to biologics or small-molecule drugs, and 6 (66.7%) developed opportunistic infections. Among CD patients, 3 (30.0%) were escalated to biologic therapy, and 2 (20.0%) developed opportunistic infections. Three patients (15.8%) underwent intestinal resection surgery.Conclusions:IBD patients with ax-SpA are predominantly male, with a similar proportion of UC and CD. There is no clear sequential pattern in the diagnosis timing of IBD and ax-SpA. These patients often present with other extraintestinal manifestations of IBD, primarily mucocutaneous manifestations.

Objective To assess the prevalence of mycoplasma genitalium(MG)in patients attending sexually transmitted disease(STD)clinic in Guangzhou,and to provide an epidemiological foundation for clinical treatment and laboratory diagnostics.Methods Utilizing real-time polymerase chain reaction(PCR),we analyzed MG DNA in 2,749 clinical specimens collected from 2,722 outpatients in the Dermatology Hospital of Southern Medical University from July 2019 to December 2021.Concurrent testing for MG,Chlamydia trachomatis(CT),and Neisseria gonorrhoeae(NG)was performed on 2,382 of these specimens.Patient data extracted from medical records were used to investigate the correlation between STD symptoms and MG infection.Results The investigation revealed that the overall prevalence of MG infection was 4.4%among the sampled patients(120 out of 2,722),with a higher prevalence in males(4.9%,or 87 out of 1,790)compared to in females(3.5%,or 33 out of 932).Notably,the prevalence decreased with increasing age.The highest incidence of MG infection was observed in females aged 18～25 years(6.4%,or 18 out of 281),while the lowest was in males aged 46 years and above(1.5%,or 5 out of 342),showing a statistically significant variation across age groups(P<0.05).Among males with urethritis symptoms,MG positive rate was significantly higher at 7.3%(42 out of 574).The rate of single MG infection was prominent,accounting for 89.9%(71 out of 79)in MG-positive male patients and 61.5%(16 out of 26)in MG-positive female patients.Co-infection rate of MG with CT was 1.2%in females and 0.3%in males,indicating a significant dif-ference(P<0.05).Conclusion The findings suggest a relatively high prevalence of MG infection and co-infection with CT among STD clinic attendees in Guangzhou,particularly in the younger demographic.The study underscores the need for early screening and vigilant surveillance of MG to mitigate its transmission among sexually active popula-tions at high risk.

Objective To explore the effect of Lee-Silverman voice treatment (LSVT) on language re-habilitation of dysarthria in Parkinson's disease (PD).Methods A total of 84 patients with PD dysarthria ad-mitted to our hospital from February 2019 to February 2022 were selected as the research objects.According to the random number table method,they were divided into observation group and control group,with 42 cases in each group.The control group received routine speech rehabilitation training,and the observation group re-ceived LSVT for four weeks.The scores of Western Aphasia Battery (WAB) and Aphasia Quotient (AQ) be-fore and after intervention were compared between the two groups,and the differences of electroglottographic parameters such as jitter,F0,shimmer,normalized noise energy (NNE) and harmonic noise ratio (HNR) were compared between the two groups.Results Before intervention,there was no significant difference in WAB scores (listening comprehension,repetition,spontaneous speech,naming) and AQ scores between the two groups (P>0.05).After intervention,the above scores of the two groups were significantly improved,and the observation group was higher than the control group,the difference was statistically significant (P<0.05). Before intervention,the jitter,F0,shimmer,NNE,HNR of vowels "a""i""u" in the two groups were not sta-tistically significant (P>0.05).After intervention,the above-mentioned electroglottic parameters of the two groups were significantly improved.The jitter and NNE of vowels "a""i""u" in the observation group were lower than those in the control group,and the HNR was higher than that in the control group,the differences were statistically significant (P<0.05).Conclusion LSVT can improve the electroglottographic parameters and speech function of patients with PD dysarthria,and the language rehabilitation effect of PD dysarthria is obvious.

Objective To investigate the protective effect of NDUFA13 protein against acute liver injury and liver fibrosis in mice and explore the possible mechanisms.Methods BALB/C mice(7 to 8 weeks old)were divided into normal group,CCl4 group,CCl4+AAV-NC group and CCl4+AAV-NDU13 group(n=18).Mouse models of liver fibrosis were established by intraperitoneal injection of CCl4 twice a week for 3,5 or 7 weeks,and the recombinant virus AAV8-TBG-NC or AAV8-TBG-NDUFA13 was injected via the tail vein 7-10 days prior to CCl4 injection.After the treatments,pathological changes in the liver of the mice were observed using HE and Masson staining.Hepatic expression levels of NDUFA13 and α-SMA were detected with Western blotting,and the coexpression of NDUFA13 and NLRP3,TNF-α and IL-1β,and α-SMA and collagen Ⅲ was analyzed with immunofluorescence assay.Results HE and Masson staining showed deranged liver architecture,necrotic hepatocytes and obvious inflammatory infiltration and collagen fiber deposition in mice with CCl4 injection(P<0.001).NDUFA13 expression markedly decreased in CCl4-treated mice(P<0.001),while a significant reduction in inflammatory aggregation and fibrosis was observed in mice with AAV-mediated NDUFA13 overexpression(P<0.001).In CCl4+AAV-NDU13 group,immunofluorescence assay revealed markedly weakened activation of NLRP3 inflammasomes(P<0.001),significantly decreased TNF-α and IL-1β secretion(P<0.001),and inhibited hepatic stellate cell activation(P<0.05)and collagen formation in the liver(P<0.001).Conclusion Mitochondrial NDUFA13 overexpression in hepatocytes protects against CCl4-induced liver fibrosis in mice by inhibiting activation of NLRP3 signaling.
