Objective: To clarify the specific mechanisms of action of raw Phellodendron chinense Schneid. (RPC) and saltwater-processed PC (SPC) in the treatment of rats with a kidney-yin deficiency pattern (KYDP). Methods: Healthy rats were administered hydrocortisone to establish a KYDP model. The rats were divided into seven groups: blank control, model, positive control (Liuwei Dihuang pills), high-dose RPC, low-dose RPC, high-dose SPC, and low-dose SPC. Enzyme-linked immunosorbent assay was used to measure the levels of cAMP, cGMP, TRH, TSH, T3, T4, IFN-γ, TNF-α, and testosterone in the serum and the levels of Na+-K+-ATPase and Ca2+-Mg2+-ATPase in the liver. TRH mRNA expression in the rat hypothalamus was measured using RT-PCR. THRα1+2 protein expression in the hypothalamus of rats was measured using Western blot. Immunohistochemistry was performed to determine the expression levels of FAS, FasL, and TSHR. Flow cytometry was used to determine CD4+ and CD8+ T lymphocyte levels. Illumina MiSeq sequencing technology was used to evaluate the diversity of intestinal flora in KYDP rats. Results: The cAMP/cGMP ratio was significantly higher in the model group than in the blank control group (P = .048). Compared with the model group, after administration, the levels of the above-mentioned serum and liver indexes decreased, except that of testosterone. The CD4+/CD8+ ratio also decreased. Compared with the RPC group, the levels of T3, IFN-γ, FAS, FasL, and TSHR in the SPC group decreased whereas that of testosterone increased. Additionally, immune function and intestinal flora diversity improved in the SPC group. SPC proved to be more effective in improving liver energy metabolism in KYDP rats than RPC. Conclusion SPC had a better therapeutic effect on KYDP than RPC. The underlying mechanism of action may be related to improvements in liver energy metabolism, immune function, and intestinal flora diversity.

Objective To explore the mediating effect of self-efficacy on social support and health-promoting lifestyle of elderly patients with chronic diseases in community. Methods By convenience sampling, 659 elderly patients with chronic diseases in a community in Minhang district of Shanghai were selected and General Information Questionnaire, General Self-efficacy Questionnaire, Social Support Scale and Health-promoting Lifestyle Scale were adopted in the questionnaire survey to investigate them. Results The self-efficacy scores of 659 elderly patients with chronic diseases were (27.598±4.907), social support scores were (38.810±5.938) and health-promoting lifestyle dimensional scores were (119.240±21.824).The total score of Social Support Scale and "objective support" dimension were positively correlated with the total score of Self-efficacy Scale (r=0.461, 0.100;P＜0.01). The total score of Social Support Scale was positively correlated with Health-promoting Lifestyle Scale(r=0.082, P＜ 0.05), and the score of self-efficacy was positively correlated with Health-promoting Lifestyle Scale(r=0.180, P＜ 0.01). Self-efficacy partially mediated between social support and health promotion (P＜ 0.01), and the mediating effect accounted for 28.3% of the total effect. Conclusions The social support, self-efficacy and health-promoting lifestyle of elderly patients with chronic diseases in community are at a medium or general level, and self-efficacy plays a part of mediating role between social support and health promotion. Medical staff should pay attention to improving the social support and self- efficacy of elderly patients with chronic diseases, so as to improve the level of health promotion lifestyle and the health condition of the elderly.

Objective:To evaluate the efficacy and safety of intensity modulated radiotherapy (IMRT) and programmed death-1 (PD-1) immunotherapy combined with single-agent chemotherapy for patients with local failure of esophageal cancer after initial radical chemoradiotherapy.Methods:Clinical data of 80 patients with local failure of esophageal cancer after initial radical chemoradiotherapy treated with IMRT or PD-1 immunotherapy combined with single-agent chemotherapy in People's Hospital of Xinghua between June 2014 and June 2023 were retrospectively analyzed. IMRT was delivered at 1.8-2.0 Gy per fraction, 5 fractions per week, with a total dose of 45.0-60.0 Gy in 40 patients (IMRT group). The other 40 patients received PD-1 immunotherapy combined with single-agent chemotherapy (PD-1 immunotherapy combined with single-agent chemotherapy group). Kaplan-Meier method was used for univariate analysis and the cumulative survival probability. Log-rank test was used for survival significance test. Cox proportional hazards model was used for multivariate analysis of related factors affecting overall survival (OS), progression-free survival (PFS) and local control (LC).Results:By December 2023, the follow-up rate was 100%. The 1- and 2-year OS rates in the IMRT group were 66.1% and 18.9%, with a median OS time of 10.1 months. In the PD-1 immunotherapy combined with single-agent chemotherapy group, the 1- and 2-year OS rates were 72.3% and 36.9%, with a median OS time of 12.4 months. There was a significant difference in OS rates between two groups ( χ2=3.89, P=0.049). The 1- and 2-year PFS rates in the IMRT group were 47.4% and 31.6%, with a median PFS time of 8.5 months. In the PD-1 immunotherapy combined with single-agent chemotherapy group, the 1- and 2-year PFS rates were 70.0% and 64.2%, with a median PFS time of 11.9 months. There was no significant difference in the PFS rates between two groups ( χ2=2.66, P=0.103). The 1- and 2-year LC rates in the IMRT group were 68.6% and 62.3%, with a median LC time of 8.9 months. In the PD-1 immunotherapy combined with single-agent chemotherapy group, the 1- and 2-year LC rates were 72.8% and 66.7%, with a median LC time of 12.0 months. There was no significant difference in LC rates between two groups ( χ2=0.18, P=0.672). Grade 2 radiation esophagitis and radiation pneumonitis developed in 82.5% (33/40) and 32.5% (13/40) in the IMRT group, respectively. The incidence of grade 1-2 peripheral blood leukopenia was 40.0% (16/40), 50.0% (20/40) for grade 1-2 peripheral blood thrombocytopenia, 27.5% (11/40) for moderate to severe anemia, and 20.0% (8/40) for grade 1-2 thyroid dysfunction in the PD-1 immunotherapy combined with single-agent chemotherapy, respectively. Single- and multi-factor analysis showed that the failure site ( χ2=9.01, P=0.011) and short-term efficacy ( χ2=7.78, P=0.005) were the independent prognostic factors affecting OS. The short-term efficacy was the independent prognostic factor for PFS ( χ2=31.63, P<0.001). The short-term efficacy was the independent prognostic factors affecting LCS ( χ2=17.64, P=0.001) too. Conclusion:For the patients with local failure of esophageal cancer after initial radical chemoradiotherapy, the combination of PD-1 immunotherapy with single-agent chemotherapy yields better survival prognosis than re-irradiation alone, but it is still necessary to pay attention to the related drug toxicities.

Objective To evaluate the impact of Montessori-based intervention on eating ability of the elderly with dementia.Methods Sixty-four patients with dementia were randomly divided into intervention group(n=32) and control group(n=32).Patients in intervention group were given Montessori-based intervention,and patients in control group received regular care.The effect of Montessori-based intervention on eating ability,eating difficulty and self-eating time were assessed by the simplified Chinese version of EBS (C-EBS),simplified Chinese version of Edinburgh feeding evaluation in dementia scale (C-EdFED) and stopwatch respectively at pre-intervention,post-intervention,1-month and 3-month follow-up.Results Compared with the control group (EBS:(12.42± 3.59);EdFED:(10.48± 3.83);self-eating time:(15.28±6.04) min)),the average scores of EBS(14.31±2.63) increased and the self-eating time ((21.44±7.17)min) increased after 8 weeks intervention in intervention group,while the average scores of EdFED (7.86±4.16) increased.The C-EBS scores and self-eating time in intervention group were significantly higher than that of control group while the C-EdFED scores were lower than that of control at all time points(P＜0.01).The difference in time effect between the two groups was statistically significant (P ＜ 0.05)Conclusion The Montessori-based intervention can improve the eating ability of elderly people with dementia,reduce eating difficulty and increase self-eating time.
