Objective:To develop the Care Needs Scale for Young and Middle-aged Terminally Ill Patients and test its reliability and validity, so as to provide an effective tool for evaluating the care needs of young and middle-aged terminally ill patients for medical and nursing staff.Methods:This study is a cross-sectional study. Guided by the theory of supportive care needs, an initial scale was formed through literature review, qualitative interviews, Delphi expert consultation, and pre-survey. From July to September 2022, convenience sampling was used to select 570 young and middle-aged terminally ill patients hospitalized in the Oncology Department and Hospice Care Ward of six Class Ⅲ hospitals in Tianjin as the research subject, and a questionnaire survey was conducted on the patients. The items in the scale were selected using item analysis method. The structural validity of the scale was evaluated using exploratory factor analysis and confirmatory factor analysis. The content validity of the scale was evaluated using the scale-level content validity index and the item-level content validity index. The reliability of the scale was evaluated using internal consistency coefficient and half reliability coefficient. A total of 570 questionnaires were distributed, and 565 valid questionnaires were collected, with an effective response rate of 99.12% (565/570) .Results:A total of 18 experts completed two rounds of consultation, with an expert authority coefficient of 0.890, the Kendall's W values of 0.309 and 0.417, respectively ( P<0.05). The Care Needs Scale for Young and Middle-aged Terminally Ill Patients included 6 dimensions and a total of 39 items. Exploratory factor analysis extracted 6 common factors, with a cumulative variance contribution rate of 71.515%. Confirmatory factor analysis showed that the overall model fitted well. The content validity index at the scale level was 0.942, and the content validity index at the item level was 0.833 to 1.000. The total Cronbach's α coefficient of the scale was 0.975, and the half reliability coefficient was 0.911. Conclusions:The reliability and validity of the Care Needs Scale for Young and Middle-aged Terminally Ill Patients are good, and it can be used as an evaluation tool for the care needs of young and middle-aged terminally ill patients.

BACKGROUND: The previous study has indicated that lung cancer has a high incidence and mortality in China, and has caused a large economic burden. The purpose of this study was to analyze the incidence and economic burden of lung cancer by analyzing the information on the home page of discharge history of lung cancer patients in Hebei Tumor Hospital, and to provide scientific basis for the prevention and treatment of lung cancer. METHODS: The information of all of the discharges, new cases, surgical patients, age, gender, length of stay and hospitalization cost of lung cancer patients in Hebei Tumor Hospital from January 2012 to December 2019 were retrieved based on the medical record management system, and the incidence trend, gender and age distribution as well as the economic burden of the disease were statistically described. RESULTS: The number of new cases of lung cancer increased year by year, from 2,235 cases in 2012 to 5,012 cases in 2019. The number of males always outnumbered females, but the gender ratio decreased year by year, from 2.25 in 2012 to 1.56 in 2019. Among new cases of lung cancer, the proportion of surgical treatment increased year by year, from 28.14% in 2012 to 44.83% in 2019. Except for 2012, the proportion of surgical operations in female patients was higher than that in male patients from 2013 to 2019. The proportion of surgical operations in male and female patients was 23.52% and 28.07% in 2013, and 36.14% and 58.37% in 2019, respectively. The median age at the onset of lung cancer has increased year by year, from 61 years old in 2012 to 63 years old in 2019. The median age of onset in all lung cancer patients was higher in males than in females. The number of new lung cancer patients and surgical patients both showed an increasing trend with the increase of age, and both reached the maximum value in the age group of 60-69 years old. With the increase of age, the number of patients gradually decreased. The median length of hospital stay for all discharged lung cancer patients or surgical patients decreased year by year, from 10 d and 19 d in 2012 to 8 d and 17 d in 2019, respectively, while the median hospitalization cost increased year by year. It increased from 10,611.46 yuan and 38,750.13 yuan in 2012 to 17,187.15 yuan and 84,030.16 yuan in 2019, respectively. CONCLUSIONS Lung cancer is still one of the main cancers endangering the health of Chinese residents. The incidence of lung cancer is increasing year by year, and the distribution of gender and age has certain characteristics. In order to reduce the number of cases and the economic burden, effective prevention and control measures should be formulated and medical reform should be strengthened.

OBJECTIVE To study the improvement effect and mechanism of Gubenanshen decoction on menopausal syndrome model rats . METHODS Totally 70 rats were anesthetized and placed on the operating table for bilateral ovariectomy to induce menopausal syndrome model . Other 10 rats without modeling were taken as sham operation group . Sixty model rats were divided into model group ，Gengniananpian group （TCM positive control group ，0.56 g/kg），Estradiol valerate tablet group （chemical drug positive control group ，0.1 mg/kg），Gubenanshen decoction high -dose，medium-dose and low -dose groups （18.0，9.0，4.5 g/kg）， with 10 rats in each group . Model group and sham operation group were given normal saline intragastrically ；administration groups were given relevant medicine intragastrically ，once a day ，for consecutive 4 weeks. After last administration ，the plasma contents of luteinizing hormone （LH），follicle stimulating growth hormone （FSH）and estradiol （E2）were determined .The indexes of uterus，adrenal gland ，spleen and thymus were measured ；pathological changes of rat uterus were observed ；mRNA expressions of kisspenptin 1（Kiss-1），inositol triphosphate receptor 1（IP3R1）and gonadotropin -releasing hormone （GnRH）in hypothalamic tissues were detected ，and the protein expressions of Kiss -1，ERK1/2 and p -ERK1/2 were also detected . RESULTS Compared with sham operation group ，the contents of LH and FSH in the plasma of rats were significantly increased in model group （P＜0.05 or P＜0.01）. The contents of E 2，organ index ，mRNA expressions of Kiss -1，IP3R1 and GnRH and protein expressions of Kiss -1 and p-ERK1/2 were decreased significantly in hypothalamic tissues （P＜0.05 or P＜0.01）. The glands of the uterus were reduced and the cells in the lamina propria were dense . Compared with model group ，above indexes of Gubenanshen decoction groups （except for the content of E 2 in the low -dose group ）were reversed significantly （P＜0.05 or P＜0.01）. The number of uterine glands increased，and single columnar epithelial cells were arranged orderly （except for the low -dose group ）. CONCLUSIONS Gubenanshen decoction can increase mRNA expressions of Kiss -1，IP3R and GnRH and protein expressions of Kiss -1 and p -ERK1/2 in hypothalamic tissues of rats ，and activate GnRH secretion signaling pathways so as to improve the menopausal syndrome .

Purpose: Drug resistance is one of the main causes of chemotherapy failure in patients with small cell lung cancer (SCLC), and extensive biological studies into chemotherapy drug resistance are required. Materials and Methods: In this study, we performed lncRNA microarray, in vitro functional assays, in vivo models and cDNA microarray to evaluate the impact of lncRNA in SCLC chemoresistance. Results: The results showed that KCNQ1OT1 expression was upregulated in SCLC tissues and was a poor prognostic factor for patients with SCLC. Knockdown of KCNQ1OT1 inhibited cell proliferation, migration, chemoresistance and promoted apoptosis of SCLC cells. Mechanistic investigation showed that KCNQ1OT1 can activate transforming growth factor-β1 mediated epithelial-to-mesenchymal transition in SCLC cells. Conclusion Taken together, our study revealed the role of KCNQ1OT1 in the progression and chemoresistance of SCLC, and suggested KCNQ1OT1 as a potential diagnostic and prognostic biomarker in SCLC clinical management.
