Objective: To investigate the current status and influencing factors for cognitive frailty among the elderly in community, so as to provide the evidence for early identification and prevention of cognitive frailty among the elderly. Methods: Residents aged 60 years and above with local household registration from 11 counties (cities, districts) in Zhejiang Province from 2021 to 2023 were selected as study participants using a multistage random sampling method. Demographic information, lifestyle, and health status were collected through questionnaire surveys. Depressive symptoms were assessed using the Patient Health Questionnaire. Cognitive frailty was evaluated using the FRAIL Scale and the Mini-Mental State Examination. Factors affecting cognitive frailty among the elderly in community were identified using a multivariable logistic regression model. Results: A total of 16 613 individuals were surveyed, including 7 465 males (44.93%) and 9 148 females (55.07%). The average age was (70.97±7.29) years. A total of 784 individuals were detected with depressive symptoms, with a detection rate of 4.72%. A total of 724 individuals were detected with cognitive frailty, with a detection rate of 4.36%. Multivariable logistic regression analysis showed that females (OR=1.419, 95%CI: 1.179-1.708), aged ≥70 years (70-<80 years old, OR=1.869, 95%CI: 1.490-2.345; ≥80 years old, OR=5.017, 95%CI: 3.935-6.398), without a spouse (OR=1.495, 95%CI: 1.234-1.810), sedentary (OR=2.420, 95%CI: 1.829-3.202), chronic diseases (1 type, OR=1.456, 95%CI: 1.175-1.804; ≥2 types, OR=1.639, 95%CI: 1.314-2.045), and depressive symptoms (OR=4.191, 95%CI: 3.361-5.225) were associated with a higher risk of cognitive frailty among the elderly in community. Conversely, a lower risk of cognitive frailty was seen among the elderly in community who had primary school or above (primary school, OR=0.512, 95%CI: 0.389-0.676; junior high school or above, OR=0.464, 95%CI: 0.354-0.608), engaged in physical exercise (OR=0.396, 95%CI: 0.291-0.539), and were reported average or good self-rated health status (average, OR=0.641, 95%CI: 0.475-0.866; good, OR=0.150, 95%CI: 0.109-0.208). Conclusions The detection rate of cognitive frailty among the elderly in community is relatively low and is influenced by demographic factors such as gender, age, education level, as well as lifestyle like sedentary and physical exercise, and health status. It is recommended to reduce the risk of cognitive frailty among the elderly through multidimensional interventions, including health education, promotion of healthy lifestyles, and enhanced mental health support.

Objective:Analyzing the influence of morphological evaluation parameters of blastocysts, including days of blastocyst development [day 5 (D5) and day 6 (D6)], degree of blastocyst expansion (4, 5, 6), inner cell mass and trophectoderm grade, on the occurrence of chromosomal karyotype abnormalities of chorionic villi in missed abortion after in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) treatment and fresh/frozen-thawed single blastocyst transfer. Methods:The clinical data of patients with missed abortion after IVF/ICSI treatment and fresh/frozen-thawed single blastocyst transfer from February 2015 to February 2023 in the Reproductive Center of the Third Affiliated Hospital of Zhengzhou University were included. Using a case-control study, the data were divided into two groups according to the detection results of chromosomal copy number variations (CNVs) in chorionic villi of missed abortion abnormal karyotype group ( n=139) and normal karyotype group ( n=82). The baseline data between the two groups were compared. Univariate logistic regression was used to investigate the effect of blastocyst morphological rating parameters on the occurrence of chromosomal karyotype abnormalities of chorionic villi in aborted tissues, and multivariate logistic regression was also used to adjust confounding factors. Results:Male age [(34.12±6.49) years], sperm morphology rate [5.00 (4.00,6.00)%] and female age [33.00 (30.00, 37.00) years] in abnormal karyotype group were higher than those in the normal karyotype group [(32.38±4.69) years, 4.00 (2.00,5.00)% and 31.50 (29.00,34.00) years], and the differences were statistically significant ( P=0.022, P=0.020, P=0.009). Univariate and multivariate logistic regression analyses showed that days of blastocyst development, degree of blastocyst expansion, inner cell mass and trophectoderm grade did not increase the risk of chromosomal karyotype abnormalities of chorionic villi (all P>0.05). Conclusion:There is no significant correlation between blastocyst morphological evaluation parameters and chromosomal karyotype abnormalities in chorionic villi of missed abortion after fresh/frozen-thawed single blastocyst transfer with IVF/ICSI treatment.

Objective:To investigate the perinatal outcome of selective fetal reduction of dizygotic twins pregnancies after double embryo transferred assisted by in vitro fertilization/ intracytoplasmic sperm injection (IVF/ICSI). Methods:The clinical data of patients with single birth who underwent IVF/ICSI after double embryo transferred from September 1, 2005 to July 31, 2020 in Reproductive Center of the Third Affiliated Hospital of Zhengzhou University were retrospectively analyzed. The patients were divided into three groups according to the occurrence of fetal reduction: 80 cases of dizygotic twins to singleton by selective fetal reduction (group A), 832 cases of dizygotic twins to singleton by spontaneous fetal reduction (group B), and 6 178 cases of singleton (group C). Using group A as the reference, after approximately propensity score matching (PSM) with 1∶4 ratio, 289 cases in group B and 271 cases in group C were obtained. The differences in baseline data and perinatal outcomes between group A and group B or group C were analyzed.Results:1) Before PSM, there were statistically significant differences in patients' age, previous fertility history, type of infertility, and stage of embryo transferred between group A and group B or group C (all P<0.05); after PSM, there were no statistically significant differences in baseline data between group A and group B or group C (all P>0.05). 2) After PSM, the premature birth rate was higher in group A than in group B [17.5% (14/80) vs. 8.7% (25/289), P=0.023] and the gestational weeks [(38.18±1.98) weeks vs. (38.64±1.83) weeks, P=0.034] were lower; group A had higher incidence rates of premature birth [17.5% (14/80) vs. 7.7% (21/271), P=0.011] and premature rupture of membranes [5.0% (4/80) vs. 0.4% (1/271), P=0.002] than those in group C, but gestational weeks [(38.18±1.98) weeks vs. (38.85±1.47) weeks, P=0.002] and birth weight [(3 253.07±475.73) g vs. (3 384.89±479.54) g, P=0.029] were lower. Conclusion:Perinatal outcomes of selective fetal reduction of dizygotic twins pregnancies after assisted by IVF/ICSI were poor. Selective fetal reduction in multiple pregnancies is not the best remedy. The strategy of selective single embryo transfer should be adopted to effectively reduce the rate of multiple pregnancies and improve maternal and infant outcomes.

OBJECT IVE To develop a rapid health technology assessment （rHTA）methodology of drugs based on evidence integration and value judgment ，which is suitable for China ’s national conditions. METHODS The literature review was adopted to study health technology assessment （HTA）and multi-criteria decision analysis （MCDA），and then rHTA method based on China ’s condition was formulated preliminarily with anti-tumor drugs ；the method of rHTA was demonstrated by expert consultation ； finally，the feasibility of rHTA was preliminarily verified taking the drugs for the treatment of non-small cell lung cancer as an example. RESULTS Established rHTA method combined the theory and principles of HTA and MCDA ：HTA method was used to guide the collection and synthesis of literature and real-world evidence ，while MCDA made the value measurements of achievable evidences by various stakeholders from different views ；it established the working process ，evaluation dimensions ，evaluation indicators and scoring system of rHTA. The feasibility of this method was verified by the drug example of treating non-small cell lung cancer. CONCLUSIONS A set of drug-driven rHTA methodology guidance based on HTA and MCDA is established. It can quickly collect and integrate evidence ，and provide evidence support for decision makers in a short time.

Objective:To analyze the expression of tuftelin protein (TUFT1) and its clinical value in hepatocellular carcinoma (HCC)-related liver cancer tissues.Methods:The biological information data of TUFT1 mRNA expression in liver cancer and non-cancer tissues were analyzed from the TCGA and Oncomine database. After the approval of the ethics committee, the self-pairing method was used to collect the postoperative cancer and para-carcinoma tissues of 132 HCC cases hospitalized between January 2009 and December 2014. Tissue microarray and immunohistochemistry (IHC) were used to analyze the expression of TUFT1 in liver tissues. According to IHC staining, liver cancer was divided into high TUFT1 and low/no expression group. Combined with clinical data, the clinicopathological characteristics were statistically analyzed between and within the groups. The 5-year overall survival (OS) and disease-free survival (DFS) was analyzed by correlation analysis.Results:IHC staining showed that TUFT1 in cancer tissue was localized in the cytoplasm and cell membrane, and its positive expression rate was significantly higher in the liver cancer group (87.1%) than the para-carcinoma group (64.4%) ( χ2 = 18.563, P < 0.001). TUFT1 expression intensity in patients with liver cancer was significantly correlated with HBeAg positive ( χ2 = 4.080, P = 0.043), tumor size ( χ2 = 9.388, P = 0.002), vascular invasion ( χ2 = 14.885, P < 0.001), TNM stage ( χ2 = 13.516, P < 0.001) and ascites ( χ2 = 5.940, P = 0.015). TUFT1 high expression was negatively correlated with OS and DFS ( P < 0.001). Conclusion:The overexpression of TUFT1 is closely related to HBV replication, vascular invasion and poor prognosis, and it is expected to become a useful marker for liver cancer diagnosis and prognosis.
