OBJECTIVES: To report the development, validation, and findings of the Multi-dimensional Attention Rating Scale (MARS), a self-report tool crafted to evaluate six-dimension attention levels. METHODS: The MARS was developed based on Classical Test Theory (CTT). Totally 202 highly educated healthy adult participants were recruited for reliability and validity tests. Reliability was measured using Cronbach's alpha and test-retest reliability. Structural validity was explored using principal component analysis. Criterion validity was analyzed by correlating MARS scores with the Toronto Hospital Alertness Test (THAT), the Attentional Control Scale (ACS), and the Attention Network Test (ANT). RESULTS: The MARS comprises 12 items spanning six distinct dimensions of attention: focused attention, sustained attention, shifting attention, selective attention, divided attention, and response inhibition.As assessed by six experts, the content validation index (CVI) was 0.95, the Cronbach's alpha for the MARS was 0.78, and the test-retest reliability was 0.81. Four factors were identified (cumulative variance contribution rate 68.79%). The total score of MARS was correlated positively with THAT (r = 0.60, P < 0.01) and ACS (r = 0.78, P < 0.01) and negatively with ANT's reaction time for alerting (r = -0.31, P = 0.049). CONCLUSIONS The MARS can reliably and validly assess six-dimension attention levels in real-world settings and is expected to be a new tool for assessing multi-dimensional attention impairments in different mental disorders.

OBJECTIVE: To compare the effects of piriformis muscle release versus preservation in total hip arthroplasty (THA) via supercapsular percutaneously-assisted total hip (SuperPATH) approach on muscle injury. METHODS: Forty-nine patients undergoing initial THA via SuperPATH approach between June 2022 and June 2023 were randomly divided into two groups, with 24 patients in trial group and 25 patients in control group. The trial group received piriformis muscle release intraoperatively, whereas the control group underwent muscle preservation. There was no significant difference in baseline data such as gender, age, body mass index, disease type, American Society of Anesthesiologists (ASA) grading, and preoperative muscle infiltration, muscle atrophy, muscle injury serological indicators, Harris score, etc. ( P>0.05). The incision length, operation time, intraoperative blood loss, total blood loss, hospital stay, preoperative and postoperative 1-day muscle injury serological indicators [including creatine kinase (CK) and lactic dehydrogenase (LDH)], and incidence of complications between two groups were recorded. Harris score was used to evaluate the recovery of hip joint function. MRI was used to evaluate the extent of hip muscle injuries (gluteus minimus, gluteus medius, piriformis, obturator internus, quadratus femoris), including tendon integrity, degree of muscle fat infiltration, and degree of muscle atrophy preoperative and 1 year postoperatively. RESULTS: The operation time, intraoperative blood loss, and total blood loss in the trial group were significantly shorter than those in the control group ( P<0.05). There was no significant difference in the incision length and length of hospital stay between the two groups ( P>0.05). Both groups showed a significant increase in serum CK and LDH levels on postoperative day 1 compared to preoperative levels ( P<0.05), but there was no significant difference between the two groups ( P>0.05). All patients were followed up, the follow-up time for the trial group and the control group was (14.8±2.8) and (15.1±3.0) months, respectively, with no significant difference ( t=-0.400, P=0.691). Incisions healed by first intention in both groups, with 1 case in the trial group and 2 cases in the control group experiencing venous thrombosis in the calf muscle space. There was no complication such as deep vein thrombosis, pulmonary embolism, hip dislocation, prosthesis loosening, or periprosthetic infection in the lower limbs. There was no significant difference in the incidence of complications between the two groups ( P>0.05). At 1 year after operation, both groups of patients showed a significant increase in Harris scores compared to preoperative levels ( P<0.05), but there was no significant difference between the two groups ( P>0.05). Compared with preoperative results, both groups showed significant fat infiltration in the piriformis and obturator muscles at 1 year after operation ( P<0.05), while there was no significant fat infiltration in the gluteus minimus, gluteus medius, and quadratus femoris muscles ( P>0.05). At 1 year after operation, except for the higher incidence of piriformis muscle fat infiltration in the control group compared to the trial group ( P<0.05), there was no significant difference in the incidence of other muscle infiltrations between the two groups ( P>0.05). At 1 year after operation, both groups of piriformis and obturator muscles showed significant muscle atrophy compared to preoperative levels ( P<0.05). The gluteus minimus and gluteus medius showed mild atrophy compared to preoperative levels, while the maximum transverse diameter of the quadriceps muscle slightly increased, but the differences were not significant ( P>0.05). There was no significant difference in the maximum cross-sectional diameter or cross-sectional area changes of each muscle between the two groups ( P>0.05). At 1 year after operation, the continuity of the gluteus medius and quadratus femoris muscles in both groups was intact. Both groups had some patients with incomplete continuity of the piriformis muscle, obturator internus, and gluteus minimus, but the difference was not significant ( P>0.05). CONCLUSION The SuperPATH approach THA may cause injury to the piriformis, gluteus minimus, and obturator internus. The piriformis muscle release does not increase muscle injury, but it can shorten the operation time and reduce bleeding.

Objective To investigate the clinical features of thyroid dysfunction in lung cancer patients treated with programmed cell death receptor-1(PD-1)or programmed cell death receptor-ligand 1(PD-L1)and their value for predicting therapeutic efficacy.Methods Lung cancer patients treated with PD-1/PD-L1 inhibitors at West China Hospital,Sichuan University between March 2018 and September 2022 were retrospectively enrolled.Data concerning the medical records,therapeutic efficacy,and thyroid function indicators of the patients were retrieved from the hospital electronic medical record information system.The data were then analyzed to identify risk factors and predictive factors for immune-related adverse events(irAEs)of the thyroid.The predictive value of thyroid irAEs for treatment efficacy and prognosis was assessed.Objective response rate(ORR)was defined as the indicator for therapeutic efficacy and progression-free survival(PFS)was defined as the prognostic indicator.Results A total of 368 lung cancer patients were enrolled.Among them,31.5％(116/368)developed thyroid irAEs.According to the results of logistic regression analysis,baseline thyroid stimulating hormone(TSH)concentration and baseline positive results for thyroglobulin antibody(TGAb)and thyroid peroxidase antibody(TPOAb)were risk factors for thyroid dysfunction caused by PD-1/PD-L1 inhibitors.Among the three measures,baseline TPOAb concentration demonstrated good predictive value for thyroid irAEs,with an area under the receiver-operating characteristic(ROC)curve(AUC)of 0.745.Patients with thyroid irAEs had a longer median PFS(16.0 months vs.9.7 months,P＜0.001)and a higher ORR(55.2％vs.34.9％,P＜0.001)compared to those without thyroid irAEs.Patients with thyroid irAEs had a better ORR than those without thyroid irAEs did.It was more likely for patients with thyroid irAEs to achieve an objective response compared to those without thyroid irAEs(odds ratio[OR]=2.29;95％CI,1.46-3.60).Conclusion In lung cancer patients treated with the PD-1/PD-L1 inhibitors,the TPOAb antibody demonstrates good predictive value for thyroid irAEs.Patients who develop thyroid irAEs have better treatment outcomes and prognosis.

Objective To investigate the density,species composition,and seasonal prevalence of domestic rodents in different habitats within Lanzhou garrisons,providing basic information for rodent prevention and control.Methods A total of 12 monitoring sites were sampled across urban,suburban,and rural residential areas from 2014 to 2022.Rodent density was monitored using the night-trapping method in the middle of odd-numbered months.Results From 2014 to 2022,346 domestic rodents were captured using 122 035 effective traps,with an average domestic rodent density of 0.28％.The highest domestic rodent density was 0.63％in 2016,and the lowest was 0.07％in 2020,showing significant differences across years,with an overall trend of initially decreasing and then increasing(χ2=136.555,P<0.001).The dominant species was Rattus norvegicus,accounting for 83.24％of the total rodents captured.Rattus norvegicus accounted for a relatively high proportion across different years,with a statistically significant difference in species composition(χ2=20.931,P<0.05).Rodent densities and species composition also varied significantly among the monitored habitats(P<0.001),with the highest densities observed in rural residential areas and the lowest in urban areas.Seasonal variation in rodent densities showed a bimodal pattern,with smaller peaks in January or March and a larger peak in July.Conclusions Domestic rodent density in Lanzhou garrisons has shown an upward trend in the past few years.Rodent control measures should focus on barracks in rural residential areas,with targeted interventions to reduce the risk of rodent-borne diseases.

Although significant progress has been made in the development of novel targeted drugs for the treatment of acute myeloid leukemia(AML)in recent years,chemotherapy still remains the mainstay of treatment and the overall survival is poor in most patients.Here,we demonstrated the antileukemia activity of a novel small molecular compound NL101,which is formed through the modification on bendamustine with a suberanilohydroxamic acid(SAHA)radical.NL101 suppresses the proliferation of myeloid malignancy cells and primary AML cells.It induces DNA damage and caspase 3-mediated apoptosis.A genome-wide clustered regularly interspaced short palindromic repeats(CRISPR)library screen revealed that phosphatase and tensin homologous(PTEN)gene is critical for the regulation of cell survival upon NL101 treatment.The knockout or inhibition of PTEN significantly reduced NL101-induced apoptosis in AML and myelodysplastic syndrome(MDS)cells,accompanied by the activation of protein kinase B(AKT)signaling pathway.The inhibition of mammalian target of rapamycin(mTOR)by rapamycin enhanced the sensitivity of AML cells to NL101-induced cell death.These findings uncover PTEN protein expression as a major determinant of chemosensitivity to NL101 and provide a novel strategy to treat AML with the combination of NL101 and rapamycin.

The aim of this study was to explore the impact of chronic apical periodontitis(CAP)on atherosclerosis in apoE-/-mice fed high-fat diet(HFD).This investigation focused on the gut microbiota,metabolites,and intestinal barrier function to uncover potential links between oral health and cardiovascular disease(CVD).In this study,CAP was shown to exacerbate atherosclerosis in HFD-fed apoE-/-mice,as evidenced by the increase in plaque size and volume in the aortic walls observed via Oil Red O staining.16S rRNA sequencing revealed significant alterations in the gut microbiota,with harmful bacterial species thriving while beneficial species declining.Metabolomic profiling indicated disruptions in lipid metabolism and primary bile acid synthesis,leading to elevated levels of taurochenodeoxycholic acid(TCDCA),taurocholic acid(TCA),and tauroursodeoxycholic acid(TDCA).These metabolic shifts may contribute to atherosclerosis development.Furthermore,impaired intestinal barrier function,characterized by reduced mucin expression and disrupted tight junction proteins,was observed.The increased intestinal permeability observed was positively correlated with the severity of atherosclerotic lesions,highlighting the importance of the intestinal barrier in cardiovascular health.In conclusion,this research underscores the intricate interplay among oral health,gut microbiota composition,metabolite profiles,and CVD incidence.These findings emphasize the importance of maintaining good oral hygiene as a potential preventive measure against cardiovascular issues,as well as the need for further investigations into the intricate mechanisms linking oral health,gut microbiota,and metabolic pathways in CVD development.

OBJECTIVE To optimize the water extraction process of Flos Lonicerae-Fructus Forsythuae and determine the range of water extraction process parameters.METHODS The active components were screened by network pharmacology,and the indica-tor ingredients were determined in combination with the quality markers under the relevant terms of Chinese Pharmacopoeia 2020 edition and the literature.Take extraction yield and the extraction rate of the indicative component as the critical quality attributes of the water extraction process to screen critical process parameters.The mathematical model was established by Box-Behnken experimental design to investigate the interaction between CQAs and CPPs and build the design space of the water extraction process of Flos Lonicerae-Fruc-tus Forsythuae.RESULTS The extraction percentages of phenolic acids,forsythoside A and forsythin were screened as the index components;specifications of medicinal slices,extraction time and water addition were the key process parameters.Based on the estab-lishment and optimization of the design space,the optimum water extraction process was obtained as follows:the medicinal slice of Lian-Qiao was broken into 0.8-1.2 cm,adding 12 times the amount of water in the first and extract for 30-50 min,10 times the a-mount of water in the second and extract for 25-30 min.CONCLUSION The verification results show that the measured value ob-tained by using the design space method to optimize the water extraction process is close to the predicted value,indicating that the method is stable and reliable,which can provide ideas for its further process development and quality control for the couple medicines of Flos Lonicerae-Fructus Forsythuae.

Objective:To evaluate the potential causal relationship between inflammatory factors and PCa using the two-sample Mendelian randomization(MR)method.Methods:We selected summary statistics of genome-wide association studies(GWAS)(n=14 824)on 91 inflammatory factors,with PCa as the outcome in the latest 9th edition of FinnGen database for MR analysis.We evaluated the causal relationship between inflammatory factors and PCa using the odds ratio(OR)and 95%confidence interval(CI)of such regression models as inverse variance weighting(IVW),MR-Egger regression,simple mode(SM),weighted mode(WM)and weighted median estimator(WME),with IVW as the main statistical method for this study.We further verified the results of MR by Bayesian analysis,and evaluated the heterogeneity of genetic instrumental variables,pleiotropic effects and sensitivity of single nu-cleotide polymorphisms(SNP)as instrumental variables to the exposure-outcome relationship by Cochran's Q test,MR-Egger intercept test and leave-one-out cross validation.Results:IVW showed that among the 91 inflammatory factors,interleukin-22 receptor A1(IL-22RA1)and sulfotransferase 1A1(ST1A1)were correlated positively with the risk of PCa;IL-22RA1:IVW(OR[95%CI]:1.12[1.00-1.25],P=0.04);ST1A1:IVW(OR[95%CI]:1.08(1.00-1.16),P=0.03),while Chemokine ligand 11(CXCL11)and interleukin 17 A(IL-17 A)negatively with the risk of PCa;CXCL11:IVW(OR[95%CI]:0.88[0.81-0.95],P=0.00);IL-17A:IVW(OR[95%CI]:0.91[0.84-0.98],P=0.02).No potential horizontal pleiotropy was detected by MR-Egger intercept analysis(P>0.05,IL-22RA1=0.885,ST1A1=0.949,CXCL11=0.391,IL-17A=0.884),nor biased SNPs in the MR pleiotropy residual sum and outlier(MR-PRESSO)test(P>0.05,IL-22RA1=0.479,ST1A1=0.629,CXCL11=0.326,IL-17A=0.444),or heterogeneity P>0.05,IL-22RA1=0.543,ST1A1=0.677,CXCL11=0.336,IL-17A=0.494).Leave-one-out sensitivity analysis indicated no significant impact of individual SNP sites on the overall causal rela-tionship prediction,suggesting the reliable results of analysis.Conclusion:Among the 91 inflammatory factors,IL-22RA1 and ST1A1 have a positive causal relationship,while CXCL11 and IL-17A have a negative causal relationship with PCa.
