RESULTS: 9 down-regulated genes and 1 up-regulated gene were identified after multidrug resistant MCF/DOX cells were treated with LY980503. CONCLUSION: LY980503 can effectively reverse the resistance of MCF/DOX to DOX in vitro by adjusting the expression of multi-genes.

ObjectiveTo investigate the clinical effect of the targeted drug sunitinib in the treatment of advanced hepatocellular carcinoma (HCC). MethodsA total of 48 patients with advanced HCC who were admitted to Chang′an Hospital form September 2015 to September 2016 were enrolled and divided into control group and observation group, with 24 patients in each group. The patients in the control group were given oral sorafenib, and those in the observation group were given oral sunitinib. The patients were followed up for 1 year, and the clinical outcome, improvement in clinical symptoms, and adverse events were recorded. The t-test was used for comparison of continuous data between groups, and the Mann-Whitney U test was used for comparison of categorical data between groups. ResultsThe disease control rate (DCR) in the observation group was 68.42% (13/19), and among these 13 patients, 4 achieved effective remission and 9 had stable disease; the DCR in the control group was 76.19%, and there was no significant difference in DCR between the two groups (P＞0.05). There was a significant difference in the incidence rate of hand-foot skin reaction between the observation group and the control group (0% vs 12.5%, U=31.07, P＜0.05). The observation group had a significantly higher incidence rate of neutropenia than the control group (25% vs 16.67%, U=29.87, P＜0.05). Both groups experienced digestive tract reactions (nausea and vomiting) and abnormal liver function; since the digestive tract reactions were tolerable, no special treatment was given, and the patients with abnormal liver function were given liver-protecting drugs, so all adverse events were effectively alleviated. ConclusionSunitinib has a good clinical effect in the treatment of advanced HCC, and further studies with a larger sample size are needed to investigate the long-term clinical effect of sunitinib and combined treatment.

Objective: To investigate the prevalence of work-related musculoskeletal disorders (WMSDs) and influencing factors among vegetable greenhouse workers, so as to provide insights into relevant intervention measurements. Methods: Workers from 4 vegetable greenhouse villages were sampled in the suburbs of Xining City using a cluster sampling method from March to April 2023. Participants' demographic information, characteristics of greenhouse operation and prevalence of WMSDs were collected using questionnaire surveys. Factors affecting the prevalence of WMSDs among vegetable greenhouse workers were identified using a multivariable logistic regression model. Results: A total of 550 questionnaires were distributed, and 518 valid questionnaires were recovered, with an effective response rate of 94.18%. There were 264 males (50.97%) and 254 females (49.03%), and 269 participants (51.93%) aged 50 years and older. The prevalence of WMSDs among vegetable greenhouse workers was 40.93% (212 cases). Waist, neck and back were mainly affected, with 185 (35.71%), 157 (30.31%), and 153 (29.54%) cases, respectively. Multivariable logistic regression analysis showed that workers who smoke (OR=2.406, 95%CI: 1.133-5.110), worked 8 hours and longer per day (OR=6.618, 95%CI: 3.492-12.542) and lift heavy loads of about 20 kg (OR=1.770, 95%CI: 1.013-3.092) had a higher risk of WMSDs. Conclusions WMSDs occurred in 40.93% of vegetable greenhouse workers in Xining City, and waist, neck and back were mainly affected. Smoking, working duration and lifting heavy loads may influence the prevalence of WMSDs among vegetable greenhouse workers in Xining City.

Objective: To investigate the prevalence of anxiety and depression among inpatients with AIDS and its influencing factors, so as to provide the evidence for improving the psychological health among inpatients with AIDS. Methods: The inpatients with AIDS that were hospitalized in an infectious disease hospital in Chengdu City were recruited using the convenient sampling method. The demographic features, depression and anxiety were collected using a self-designed questionnaire, Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale ( SDS ), respectively, and factors affecting the development of depression and anxiety were identified using a multivariable linear regression model among inpatients with AIDS. Results: The 228 AIDS inpatients included 186 men (81.58%) and 42 women ( 18.42% ), and had a mean age of ( 48.04±16.03 ) years. There were 113 inpatients ( 49.56% ) with a CD4+T cell count of ≤200 cells/μL, and the mean SAS and SDS standardized scores were 35.87±8.01 and 42.07±11.08 among AIDS inpatients, which were both significantly greater than in normal populations ( P<0.05 ). The prevalence rates of anxiety, depression, and comorbid anxiety and depression were 5.26%, 16.23% and 4.82% among the participants, respectively. Multivariable linear regression analysis identified unemployment as a risk factor of anxiety ( β'=0.168, P<0.05 ), and CD4+T cell count as a risk factor of anxiety ( β'=-0.151, P<0.05 ) and depression ( β'=-0.238, P<0.05 ) among inpatients with AIDS. Conclusions Anxiety and depression are prevalent among inpatients with AIDS. Unemployment and a low CD4+T cell count may cause a rise in the risk of developing anxiety and depression among inpatients with AIDS.
