Objective To translate the Urinary Incontinence Awareness and Attitude Scale(URINAS)and test its reliability and validity.Methods The Chinese version of the URINAS was developed by Brislin's translation model for translation,back translation,cultural adaptation,and pilot investigation.A convenience sampling method was used to select 384 urinary incontinence patients who visited a tertiary hospital in Nanchang,Jiangxi Province from June 2024 to October 2024 for investigation,in order to evaluate the reliability and validity of the scale.Results The Chinese version of the URINAS consisted of 5 dimensions with 26 entries.The Cronbach's alpha coefficient of this scale was 0.843;the folded half reliability was 0.917;the retest reliability was 0.852.The content validity of the scale at the level of the entries ranged from 0.846 to 1.000,and that at the level of the scale was 0.979.A total of 5 metrics were extracted by exploratory factor analysis,and the cumulative variance contribution rate of 74.286％.The results of the validation factor analysis showed a chi-square/degree of freedom of 2.268,a root mean square error of approximation of 0.064,a standardized fit index of 0.916,a Tucker-Lewis index of 0.923,a comparative fit index of 0.906,and a goodness-of-fit index of 0.922.Conclusion The URINAS has good reliability and validity,and can better reflect the level of patients' cognition and attitude towards urinary incontinence,thus providing theoretical basis for the development of corresponding intervention programs for such patients.

OBJECTIVES: To explore the relationship between the Observer's Assessment of Alertness/Sedation (OAAS) score and the bispectral index (BIS) during propofol titration for general anesthesia induction and analyze the impact of BIS monitoring delay on anesthetic depth assessment. METHODS: This study was conducted among 90 patients (ASA class I-II) undergoing elective surgery under general anesthesia. For anesthesia induction, the patients received propofol titration at the rate of 0.5 mg·kg^-1·min^-1 till OAAS scores of 4, 3, 2, and 1 were reached. After achieving an OAAS score of 1, remifentanil (2 μg·kg⁻¹) and rocuronium (0.6 mg·kg⁻¹) were administered, and tracheal intubation was performed 2 min later. BIS values, mean arterial pressure (MAP), heart rate (HR), and propofol dosage at each OAAS score were recorded, and the correlation between OAAS scores and BIS values was analyzed. The diagnostic performance of BIS values for determining when the OAAS score reaches 1 was analyzed using ROC curve. RESULTS: All the patients successfully completed tracheal intubation. BIS values of the patients at each of the OAAS scores differed significantly (P<0.01), and the mean BIS value decreased by 4.08, 8.32, 5.43 and 5.24 as the OAAS score decreased from 5 to 4, from 4 to 3, from 3 to 2, and from 2 to 1, respectively. There was a significant correlation between the OAAS score and BIS values (ρ=0.775, P<0.001). The median BIS value for an OAAS score of 1 was 76, at which point 83.33% of the patients had BIS values exceeding 60. ROC curve analysis showed that for determining an OAAS score of 1, BIS value, at the optimal cutoff value of 84, had a sensitivity of 88.9%, a specificity of 73.3%, and an area under the curve of 0.842 (0.803-0.881). CONCLUSIONS OAAS score during induction of general anesthesia is strongly correlated with BIS value and is a highly sensitive and timely indicator to compensate for the delay in BIS monitoring.

Objective To establish a model to predict the severity of patients with COVID-19 associated diarrhea by analyzing the differences of laboratory detection indicators in different grades of patients with COVID-19 associated diarrhea.Methods A total of 649 COVID-19 patients combined with diarrhea hospitalized in Wuhan Huoshenshan Hospital from February 2020 to April 2020 were retrospectively selected,and the patients with obvious causes of diarrhea had been excluded.They were further divided into the common group(n=282),severe group(n=314),and critical group(n=53),and the differences in clinical and laboratory indicators among the three groups were compared.The XGBoost model was established,and its diagnostic efficacy in predicting the severity of patients with COVID-19 associated diarrhea was evaluated by the ROC curve.Results There were statistically significant differences in blood routine test,liver function,electrolytes,fecal occult blood and other laboratory indicators among the three groups of COVID-19 associ-ated diarrhea(P＜0.05).The white blood cell count,absolute value and percentage of neutrophils,and levels of serum lactate dehydro-genase(LDH),α-hydroxybutyrate dehydrogenase(α-HBDH),γ-glutamyl transpeptidase(GGT),B-type natriuretic peptide,and blord glucose(Glu)in the critical group were significantly higher than those in the common group and severe group(P＜0.05),while the percentages of lymphocytes,monocytes,eosinophils,and basophils,and chloride concentration were significantly lower than those in the common group and severe group(P＜0.05).The results of the ROC curve showed that the prediction model constructed by eight indicators,including C-reactive protein(CRP),LDH,interleukin-6(IL-6),Glu,PT％activity,chloride(Cl-),D-dimer(DD),and procalcitonin(PCT),had significant predictive value for critical patients(AUCROC=0.939),but no obvious predictive value for the patients in the common group(AUCROC=0.630)and severe group(AUCROC=0.553).Conclusion The COVID-19 patients com-bined with diarrhea have a higher probability of developing severe or critical conditions compared with those without diarrhea.The indi-cators such as CRP,LDH,IL-6,Glu,PT％activity,Cl-,DD,and PCT have significant predictive value on whether the COVID-19 patients combined with diarrhea turn to critical illness.

The lip plays a crucial role in facial aesthetics,making them a focal point of interest for orthodontists and patients through-out orthodontic treatment due to their three-dimensional changes in morphology and position.The degree of improvement in lip morphol-ogy significantly impacts post-treatment satisfaction among orthodontic patients.Therefore,understanding the influencing factors of lip morphology and its correlation with orthodontic interventions enables orthodontists to predict post-treatment changes in lip morphology more accurately,facilitating the customization of orthodontic treatment plans.In this paper,we reviewed the progress of methods for evaluating lip morphology and its influencing factors in order to provide reference for clinical practice.

Objective : To explore differential expression of insulin like growth factor 1( IGF1) in oral squamous cell carcinoma (OSCC) tissues and cells , and to analyze its clinical significance of IGF1 . Methods : The protein expression of IGF1 was detected in 115 OSCC tissues (OSCC group) and 74 normal tissues (normal group) using immunohistochemical technique , and the relationship with the clinicopathological factors and prognosis of OSCC was analyzed. The IGF1 protein and mRNA levels in HOK and OSCC cell lines ( CAL⁃27 , TCA⁃8113 , SCC⁃15 and SCC⁃25) were detected by Western blot and qRT⁃PCR. Results : The high expression rate of IGF1 in OSCC group was 72. 17% , which was significantly higher than that in normal group (2. 70% ) ( P < 0. 001) . The proportion under ROC curve (AUC) of OSCC diagnosed by IGF1 was 0. 81 , the sensitivity was 0. 73 , and the specificity was 0. 82. The expression of IGF1 was related to the degree of differentiation , T stage and depth of invasion (P = 0. 03 , P = 0. 02 , P = 0. 02) , but not to gender, age , N stage , TNM stage , smoking , alcohol consumption , or HPV infection (P > 0. 05) . Kaplan⁃Meier and COX regression analysis showed that the high expression of IGF1 , the degree of differentiation , the T stage and the depth of infiltration were the related factors affecting the prognosis of patients (P < 0. 01 , P = 0. 04 , P = 0. 03 , P = 0. 04) . COX multivariate indicated that high expression of IGF1 was an independent factor affecting the prognosis of patients ( P = 0. 01) . Western blot and qRT⁃PCR results indicated that the expression of IGF1 in OSCC cell lines was higher than that in HOK (P < 0. 05) . Conclusion IGF1 can be a potential diagnostic and poor prognostic marker in oral squamous cell carcinoma.
