Purpose:To evaluate the clinical efficacy ,clinical-benefit-response (CBR) and toxicity of gemcitabine single-agent in the treatment of elderly advanced cancer. Methods:54 elderly patients with grade Ⅲ/Ⅳ were treaded with gemcitabine 1 000 mg/m~(2) on day 1,8 and 15 in each 28-day cycle. The clinical efficacy and toxicity were estimated according to the standard of WHO and the CBR was evaluated simultaneously. Results:Of 32 advanced NSCLC patients , obtained the partial response (PR) of 21.88% .The CBR rate of 90.7% was reached in 54 patients. The toxicity was mild and well tolerated for elderly patients. Conclusions:Gemcitabine single-agent in the treatment of elderly advanced cancer is highly effective, low toxic and safe. Therefore, it could be considered as first line therapy for elderly advanced cancer.

Objective:This work aims to explore the application value of cervical exfoliated cell DNA (Cysteine dioxygenase type 1, CDO1 and CUGBP Elav-like family member 4, CELF4) methylation in the detection of endometrial cancer in women of childbearing age. Methods:From November 2021 to October 2022, a prospective study was conducted on a total number of 517 reproductive-age women with abnormal uterine bleeding who had surgical indications for hysteroscopy at the Xiangya Third Hospital of Central South University. The cervical exfoliated cells were collected for cytology, HPV (human papillomavirus) and gene methylation detection before operation. Clinical information of patients, level of tumor-related biomarkers, and endometrial thickness of transvaginal ultrasound (TVS) were also collected. Single factor regression method was used to analyze the high-risk factors of endometrial cancer. Receiver operating characteristic curve analysis was used to obtain the area under the curve(AUC), focusing on the screening efficacy of gene methylation test for endometrial cancer in women of childbearing age.Results:The age, body mass index (BMI)≥25 kg/m 2, endometrial thickness≥11 mm, CDO1 m ΔCt≤8.4, CELF4 m ΔCt≤8.8, and double gene methylation were associated with endometrial cancer in women of childbearing age, 1.16(1.08-1.25), 4.33(1.89-10.31), 9.49(3.88-26.69), 69.62(25.70-224.36), 23.64(9.66-63.99), 87.39(24.83-555.05), all P<0.05. The AUC was 0.90 (95% CI 0.83-0.97) of CDO1 m/ CELF4 m in diagnosing endometrial carcinoma was higher than others factors, with sensitivity and specificity of 91.7% (95% CI 80.6%-100%) and 88.8% (95% CI 86.0%-91.6%). TVS combined with DNA methylation detection further improved the sensitivity to 95.8% (95% CI 87.8%-100%), but could not improve the specificity 68.0% (95% CI 63.8%-72.1%). Conclusions:For women of childbearing age with abnormal uterine bleeding or abnormal vaginal discharge, the accuracy of cervical cytology DNA methyl detection of endometrial cancer is better than other non-invasive clinical programs. DNA methylation combined with TVS can improve the sensitivity of detection.

OBJECTIVES:
To develop a Chinese version of the Long-Term Conditions Questionnaire (LTCQ) and to test its reliability and validity in Chinese patients with chronic diseases.
METHODS:
With the consent of the original authors, a Chinese version of LTCQ was developed according to the cultural adjustment guidelines. A questionnaire survey was conducted on 319 patients with chronic diseases in Sir Run Run Shaw Hospital, Wuyi County First People's Hospital and Hangzhou Gongchen Bridge Street Health Service Center. The questionnaire was evaluated by item analysis (including frequency analysis, total question correlation method and critical ratio method), reliability analysis (Cronbach's alpha coefficient) and validity analysis [including content validity (expert scoring method) and structural validity (exploratory factor analysis)].
RESULTS
The Chinese version of the LTCQ included 20 entries, with a Cronbach's alpha coefficient of 0.926, a retest reliability of 0.829, a split-half reliability of 0.878, an entry content validity index of 1, and a content validity index at the questionnaire level of 1. Four common factors were extracted by exploratory factor analysis, namely physical state and daily life, psychological state, support and coping, and safe environment, with a cumulative variance contribution rate of 67.244%. Discussion: The Chinese version of the LTCQ developed in this study has good reliability and validity and it may be used to assess the long-term conditions of patients with chronic diseases in China.

OBJECTIVES:
To develop a Chinese version of the Stress Adaption Scale (SAS) and to assess its reliability and validity among Chinese patients with multimorbidity.
METHODS:
The Brislin model was used to translate, synthesize, back-translate, and cross culturally adapt the SAS. A total of 323 multimorbidity patients selected by convenience sampling method from four hospitals in Zhejiang province. The critical ratio method, total question correlation method, and graded response model (item characteristic curve and item discrimination) were used for item analysis. Cronbach's alpha coefficient and split-half reliability were used for the reliability analysis. Content validity analysis, structural validity analysis, and criterion association validity analysis were performed by expert scoring method, confirmatory factor analysis, and Pearson correlation coefficient method, respectively.
RESULTS:
The Chinese version of the SAS contained 2 dimensions of resilience and thriving, with a total of 10 items. In the item analysis, the critical ratio method showed that the critical ratio of all items was greater than 3.0 (P<0.001); the correlation coefficient method showed that the Pearson correlation coefficients for all items exceeded 0.4 (P<0.01). The graded response model showed that items of the revised scale exhibited distinct item characteristic curves and all items had discrimination parameters exceeding 1.0. In the reliability analysis, Cronbach's alpha coefficient of the revised Chinese version of the SAS scale was 0.849, and the split-half reliability was 0.873. In the validity analysis, the item-level content validity index and scale-level content validity index both exceeded 0.80. In the confirmatory factor analysis, the revised two-factor model showed satisfactory fit indices (χ2/df=3.115, RMSEA=0.081, RMR=0.046, GFI=0.937, AGFI=0.898, CFI=0.936, TLI=0.915). In the criterion-related validity analysis, the Chinese version of the SAS score was negatively correlated with the Perceived Stress Scale and the Treatment Burden Questionnaire, with correlation coefficients of -0.592 and -0.482, respectively (both P<0.01).
CONCLUSIONS
The Chinese version of the SAS has good reliability and validity, which can be used to evaluate the stress adaption capacity among multimorbidity patients in China, and provides a reference for developing individualized health management measures.
