(+)-Strebloside, a significant bioactive compound isolated from the roots of Streblus asper Lour., demonstrates inhibitory effects against multiple malignancies. However, its specific function and underlying mechanistic pathways in Non-Hodgkin lymphoma (NHL) remain unexplored. This investigation sought to elucidate the role and potential mechanisms of (+)-strebloside-induced NHL cell death. The results demonstrated that (+)-strebloside significantly induced apoptosis and ferroptosis in NHL cells, including those from Raji cell-derived xenograft models. Mechanistic analyses revealed that (+)-strebloside enhanced six-transmembrane epithelial antigen of prostate 3 (STEAP3)-induced ferroptosis in NHL, and STEAP3 inhibition reduced the proliferation-inhibitory effects of (+)-strebloside. Furthermore, (+)-strebloside suppressed NHL proliferation through the mitogen-activated protein kinase (MAPK) pathway, and extracellular signal-regulated kinase (ERK) inhibition diminished the proliferation-inhibitory activity induced by (+)-strebloside. These findings indicate that (+)-strebloside presents promising therapeutic potential for NHL treatment.

Objective:To construct a nursing quality evaluation index system for midline catheters, so as to provide a reference for the objective and scientific evaluation of the nursing quality of midline catheters.Methods:Taking Donabedian's structure-process-outcome as the theoretical framework, the nursing quality evaluation index system for midline catheters was preliminarily formulated through literature review and semi-structured interview. From July to September 2021, two rounds of expert consultation were conducted through Delphi method and analytic hierarchy process to establish the quality evaluation index system and the weight of each index.Results:The constructed nursing quality evaluation index system for midline catheters included three first-level indicators, 14 second-level indicators, and 73 third-level indicators. Among two rounds of consultation, the positive coefficients of experts were all 100%, the authority coefficients were 0.819 and 0.831, and the coordination coefficients were 0.218 and 0.220, respectively.Conclusions:The constructed nursing quality evaluation index system for midline catheters was extremely scientific, practical and feasible, which can provide a reference for clinical nurses to continuously improve the nursing quality of midline catheters.

Objective:To investigate the main postoperative complications, causes of death and the risk factors for survival in patient with benign end-stage lung diseases within 1 year after lung transplantation.Methods:A retrospective analysis was conducted to collect the clinical data of 200 patients with benign end-stage lung disease who underwent lung transplantation admitted to Wuxi People's Hospital Affiliated to Nanjing Medical University from May 2017 to October 2018. The main postoperative complications, survival and causes of death within 1 year after operation were analyzed. The Kaplan-Meier method was used to plot survival curves, and the Log-Rank test was used to compare the influence of factors, including recipient's gender, use of marginal donor lung, primary disease, preoperative combination of moderate to severe pulmonary hypertension (PAH), intraoperative extracorporeal membrane oxygenation (ECMO) support, surgical methods, intraoperative massive blood loss, postoperative complications [infection, primary graft dysfunction (PGD), acute rejection], on 1-year survival in patients who underwent lung transplantation. The multivariate Cox proportional hazards regression model was used to evaluate the risk factors of death within 1 year after lung transplantation.Results:Two hundred patients underwent successful lung transplantation. The major postoperative complications within 1 year after transplantation included infection in 131 patients, PGD in 20 patients, acute rejection in 57 patients, anastomotic complication in 26 patients and others (new onset diabetes, osteoporosis, etc.) in 53 patients. The 3-month, 6-month, and 1-year postoperative cumulative survival rates were 81.5%, 80.0% and 77.5%, respectively. Forty-five patients died during 1 year after operation, among whom 14 died of infection, 7 died of PGD, 8 died of acute rejection, 4 died of anastomotic complication, 3 died of cardio-cerebrovascular accident, 3 died of multiple organ failure, 2 died of respiratory failure and 4 died of other causes (traffic accident, etc.). The Kaplan-Meier survival analysis showed that recipient's gender, idiopathic pulmonary fibrosis (IPF) as the primary disease, preoperative combination of moderate and severe PAH, intraoperative ECMO support, intraoperative massive blood loss, postoperative complications (infection, PGD, acute rejection) were influencing factors for postoperative 1-year survival rate. The multivariate Cox regression model showed that male was the protective factor [hazard ratio ( HR) = 0.481, 95% confidence interval (95% CI) was 0.244-0.947, P = 0.034], IPF as the primary disease ( HR = 2.667, 95% CI was 1.222-5.848, P = 0.014), intraoperative use of ECMO support ( HR = 1.538, 95% CI was 0.787-3.012, P = 0.028), massive blood loss during surgery ( HR = 2.026, 95% CI was 0.976-4.205, P = 0.045) and postoperative infection ( HR = 3.138, 95% CI was 1.294-7.608, P = 0.011), PGD ( HR = 1.604, 95% CI was 0.464-5.539, P = 0.004), and acute rejection ( HR = 1.897, 95% CI was 0.791-4.552, P = 0.015) were the independent risk factors for death within 1 year after transplantation. Conclusions:One-year survival rates after lung transplantation are affected by recipient's gender, primary disease, preoperative combination of moderate and severe PAH, intraoperative ECMO support, intraoperative massive blood loss, and postoperative complications (infection, PGD, acute rejection). The male is the protective factor, while IPF as the primary disease, intraoperative ECMO support, massive blood loss during surgery and postoperative complications (infection, PGD, acute rejection) are independent risk factors for death within 1 year after lung transplantation.

OBJECTIVES: To observe the efficacy and adverse reactions of the combination of endostar with chemotherapy in the treatment of advanced (IVb) and recurrent metastatic cervical cancer. METHODS: Forty-four patients with recurrent and metastatic cervical cancer, who were admitted to the Second Xiangya Hospital, Central South University from December 2016 to December 2018 were randomly divided into an experimental group and a control group (22 cases in each group). The control group was given gemcitabine plus cisplatin (GP) or docetaxel plus cisplatin (DP) treatment, the experimental group was treated with endostar on the basis of the control group. RESULTS: The objective response rate (ORR) was 42.9% in the experimental group and 22.7% in the control group. There was no significant difference between the 2 groups ( CONCLUSIONS Compared with chemotherapy alone, endostar combined with chemotherapy can prolong the median progression-free survival, with higher ORR and similar adverse reactions.

Objective To study the effect of age-related white matter changes (ARWMC) on first symptomatic ischemic stroke events in the oldsters. Methods For the prospective study, a total of 368 eligible oldsters were enrolled in the study from January 2010 to August 2012. The degrees of ARWMC were assessed by ARWMC scale;according to the scores, they were divided into non ARWMC group, mild-moderate ARWMC group and severe ARWMC group. The patients were followed up once every 3 months. The clinical endpoint events and time (first symptomatic ischemic stroke, myocardial infarction and all-cause death) were recorded. Analyses of variance and Chi-square test were used to compare the differences of clinical data among the 3 groups. COX regression was used to assess the risk differences of first symptomatic ischemic stroke in the oldsters of three groups. Results After an average of follow-up for 48.7 months, 50 participants (13.6％) had first symptomatic ischemic stroke;25 (25.8％) were categorized as the severe ARWMC group, 22 (10.9％) were as the mild-medium group, and 3 (4.4％) were as the non ARWMC group. Among the three groups, the differences in age, history of hypertension, systolic blood pressure, incidence of clinical endpoint events and first symptomatic ischemic stroke, and follow-up time of endpoint events were statistically significant (P<0.05); patients from the severe ARWMC group were the oldest, and had the longest history of hypertension, the highest systolic blood pressure, the highest incidence of clinical end events and first symptomatic ischemic stroke, and the shortest follow-up period for clinical end events. COX regression analysis showed that the risk of first symptomatic ischemic stroke in the severe ARWMC group was about 8 times higher than that in the non ARWMC group (hazard ratio=9.012, 95％CI: 2.310-35.154, P=0.002). Conclusion In oldsters, severe ARWMC often accompany hypertension history and poor blood pressure controll, and it is an independent and serious risk factor for long-term first symptomatic ischemic stroke.

Objective To indentify the cognitive status of Chinese patients to acne and the influencing factors to theirs' cognitive status,so as to provide solid evidences for the prevention and treatment of acne.Methods A self-designed questionnaire was made to conduct this survey of 16,156 acne patients,who seeked to the treatment in the dermatological departments from 112 hospitals in China.The survey consisted of several parts,including the general status of patients,the patients' cognition of occurrence,development and risk factors of acne,whether the first choice was seeking treatment at the hospital when the patients had acne and the condition of selection of skin care products.The factors were analyzed,which could impact the cognition of the patients' behavior of treatment,how did the patients' cognition to influence their medical behavior and skin care as well as the consistency of assessment of the severity of acne by doctors and patients themselves.Results The acne patients studied had the best knowledge of "acne is a skin disease","it not only occurs in the period of adolescence" and "the disease can be prevented and cured",which accordingly accounted for 80.65％,69.16％ and 65.49％ of the total patients respectively.However,the awareness of acne patients to heredity,high sugar and dairy products as risk factors for acne was insufficient,which accounted for 48.72％,42.40％ and 18.25％ of the total patients,respectively.Gender,age,educational level,occupation and health knowledge were the main factors affecting the cognitive level of patients;the survey also found that men,patient with educational level of junior high or even lower educational condition,occupation of labor workers or farmers and patients were lack of health education with poor knowledge of the genetics and dietary were risk factors for acne;patients with age over 36 years or with mild illness had poor knowledge of dietary risk factors for acne;the difference was statistically significant (P＜0.05).The analysis of the influence of cognitive status on medical treatment behavior and skin care showed that the better the cognition,the higher the probability of patients would choose medical treatment as the first choice as well as choosing functional skin care products;the difference was statistically significant (P＜0.05).The consistency of assessment of the severity of acne by doctors and patients was poor (Kappa value ＜0.4),and the assessment of severity of acne by patients was more serious than doctors' assessment.Conclusions Patient's cognitive status will affect their medical behavior and skin care,and there is also a phenomenon that patients have a more serious assessment of their acne condition.It is suggested that health education for acne patients should be strengthened in clinical medicine so as to improve their knowledge of acne as well as preventing from acne effectively.

OBJECTIVETo determine measles antibody levels and influencing factors among children aged 6 to 15 years in Zhejiang province.

METHODSBlood samples were collected from 2069 children aged 6 to 15 years in Changxing county (Huzhou) and Liandu district (Lishui) of Zhejiang province. Serum level of measles IgG antibody was measured using ELISA, and 800 mIU/mL was applied as the cut-off point of high antibody level. Chi-square or trend Chi-square test was used to analyze difference in positive rates of high antibody level among children with different characters, and the factors related to high antibody level in the vaccinated children were analyzed using multivariate logistic regression.

RESULTSAmong 2069 subjects, positive rate of high measles antibody level was 36.06% (746/2069). Multivariate logistic regression showed that the high measles antibody level was significantly associated with age of children and the age of first measles vaccine inoculation. The positive rate of high measles antibody level decreased with age(=0.866, 95%:0.830-0.904, <0.01), and the positive rate in children whose first vaccination at ≥ 12 months of age was higher than those whose first vaccination at 8 months of age(=0.633, 95%:0.498-0.805, <0.01).

CONCLUSIONSIn order to obtain high measles antibody level and to maintain high levels of population immune barrier, it is suggested that first dose of vaccination can be appropriately delayed in low epidemic areas, and elder children should have timely catch-up vaccination.
