ObjectiveTo explore the mental health status of patients with breast cancer and social support on their influence. Methods260 cases of patient with breast cancer were investigated by using the questionnaire of demographic characteristics and symptom check list 90(SCL-90)and social support rating scale(SSRS). ResultsBreast cancer patients ' mental health condition was worse than normal healthy people and their mood changes were obviously observed. Breast cancer patients achieved good social support.However, the urban patients with breast cancer got better social support than the rural patients and the difference were statistically significant(t =7.91, P =0.000). SCL-90 total score and its factors such as forced symptoms, sensitive interpersonal relationship, depression, anxiety, hostile, terror, paranoid,psychoticism,were negatively related with the social support (r =-0.278,-0.259,-0.165,-0.294,-0.215,-0.177,-0.175,-0.167,-0.219,all P ＜ 0.05).ConclusionThe social support influences breast cancer patients'mental health,therefore,the patients with breast cancer should be given a better social support in order to improve the psychological health level and improve recovery.

It is essential that public hospitals,as the main body of China's health care service system,must uphold the overall leadership of the Communist Party of China(CPC)to achieve high-quality development in the new era,which requires the deep integration of Party building and hospital operation.Since the CPC's 18th National Congress,public hospitals have actively strengthenedprimary-level Party building by consolidating the foundation,which has largely contributed to advancing the Healthy China Initiative and optimizing the allocation of medical resources.However,there remain some problems in the integration of Party building and hospital operation,such as insufficient understanding of the integration and simple methods to achieve it,lead-ing to inadequate integration in some hospitals.By analyzing of the causes of above problems,based on Sun Yat-sen Memorial Hospital,Sun Yat-sen University's practices in Party building,the author actively explores the effective path of deep integration of party building and business work in public hospitals from the aspects of promoting party building and theoretical learning,sys-tem design,team building and business characteristics.In order to provide useful references for public hospitals to achieve high-quality development in the new era.

Objective To explore the application effect of volunteer service in the practical teaching of Traditional Chi-nese Pediatrics.Methods In 2023,80 undergraduate interns from the 2021 cohort at Yunnan University of Traditional Chinese Medicine,who were shadowing in the pediatrics department of a traditional Chinese medicine hospital in Yunnan,were randomly selected as research subjects.They were divided into an experimental group and a control group.The experimental group received teaching through a combination of volunteer service and traditional teaching methods,while the control group was taught using tra-ditional classroom methods.Results The experimental group scored significantly higher than the control group in clinical skills assessments,Mini-CEX scores,subject recognition evaluations,and teaching satisfaction,with statistically significant differences(P＜0.05).Conclusion The use of volunteer service in the practical teaching of Traditional Chinese Pediatrics is highly feasi-ble and can significantly enhance students'clinical practice abilities,stimulate their enthusiasm for learning,foster independent thinking,and improve their overall clinical competencies.

Objective:To investigate the effects of Houttuynize Herba decoction on aspirin-induced gastric ulcer (GU) in mice; To discuss its mechanism.Methods:A total of 64 SPF male mice were selected, and 48 mice were randomly selected to establish the model by gavage of 20 mg/ml aspirin solution. The remaining 16 rats were treated as normal group by gavage with the same amount of normalsaline once a day for 7 consecutive days. After successful modeling, the remaining mice in the model group were randomly divided into 5 groups, with 8 mice in each group, namely normal saline group (given normal saline), omeprazole group (given omeprazole 0.5 mg/ml), Houttuynize Herba high-, medium- and low-dosage groups (given 1.08 g/ml, 0.54 g/ml, 0.27 g/ml), and the remaining 8 mice in the normal group were given the same amount of normal saline by gavage. The mice were treated by gavage once a day for 7 days. The number of Escherichia coli and Bifidobacterium in mouse feces was counted by bacterial culture method, and the ratio of Bifidobacterium to Escherichia coli (B/E value) was used to judge the imbalance of bacterial flora. The expression of interleukin-6 (IL-6) in serum was detected by magnetic particle chemiluminescence. Enzyme-linked immunosorbent assay (ELISA) was used to detect the expression of prostaglandin E 2 (PGE 2) in the serum of mice to determine the level of inflammation. Hematoxylin-eosin staining was used to determine the ulcer and healing. ImageJ 1.8.0 was used to calculate the ulcer inhibition rate. The protein expression levels of IκBα, NF-κB-p65 subunit and phosphorylated IκBα (p-IκBα) and p65 (p-NF-κB-p65) subunits in gastric tissue of mice were evaluated by Western blot. Results:Compared with the normal group, the epithelial cells of the gastric mucosa were missing, the glands were irregularly arranged, and the tissue structure was severely damaged in the modeling group; the number of Escherichia coli in the intestine increased ( P<0.01), the number of Bifidobacterium decreased ( P<0.01), and the B/E value was less than 1 ( P<0.01); Serum PGE2 levels were decreased ( P<0.01), IL-6 levels were increased ( P<0.01); The expression of p-IκBα and p-NF-κB-p65 proteins in gastric tissues was elevated ( P<0.05). After 7 days of drug treatment, compared with the saline group, gastric mucosal cells and structures were improved, and weight gained in the Houttuynize Herba groups ( P<0.05); the rate of inhibition of ulcers in mice in the Houttuynize Herba high-dosage group was significantly improved ( P<0.01); the number of Bifidobacteria in the intestinal tract significantly increased ( P<0.01), that of Escherichia coli was diminished ( P<0.05), B/E value was greater than 1 ( P<0.05), IL-6 content in peripheral blood was reduced ( P<0.05), PGE 2 levels significantly increased ( P<0.01); the level of p-IκBα/IκBα and p-NF-κB-p65/NF-κB-p65 in the gastric tissues of mice decreased ( P<0.01). Conclusion:Houttuynize Herba decoction can effectively improve gastric mucosal injury in mice, and its mechanism may be related to regulating intestinal microorganisms, inhibiting the opening of IκBα/NF-κB pathway, and reducing inflammatory response.

Objective To compare the therapeutic effects between three-dimensional conformal radiotherapy (3DCRT) and intensity-modulated radiotherapy (IMRT) in patients with stage Ⅱ/Ⅲ esophageal cancer and investigate the prognostic factors.Methods Medical record of 2 132 patients with stage Ⅱ/Ⅲ esophageal cancer who underwent definitive radiotherapy with/without chemotherapy in 10 hospitals from January 2002 to December 2016 from were retrospectively analyzed.Among these patients,37.9％ of them were aged ≥ 70 years,33.9％ with neck and upper esophageal tumors and 66.1％ with middle and lower esophageal and borderline tumors.The median gross tumor volume (GTV) and lymph node gross tumor volume (GTVnd) was 41.6 cm3.Among them,32％ were stage Ⅱ] and 68％ were stage Ⅲ.A total of 723 patients received 3DCRT and 1 409 cases received IMRT.Patients received an equivalent dose in 2 Gy (EQD2) ≥ 60 Gy accounted for 86.1％,and 41.1％ of them received concurrent chemoradiotherapy.Results The median follow-up time was 60.8 months.The 1-,3-and 5-year overall survival (OS) of all patients was 73.9％,41.7％ and 32.6％,and the 1-,3-and 5-year progression-free survival (PFS) was 62.2％,37.3％ and 32％,respectively.Multivariate analysis demonstrated that age,primary tumor location,clinical stage,tumor target volume,EQD2 and concurrent chemoradiotherapy were the independent prognostic factors for OS.Age,primary tumor location,clinical stage,tumor target volume and EQD2 were the independent prognostic factors for PFS.The OS and PFS did not significantly differ among the low-risk,low-/moderate-risk,moderate-/high-risk and high-risk groups according to age≥70 years,tumor diameter＞5 cm,tumor volume ≥41.6 cm3 and stage Ⅲ (P＜0.001).After the propensity score matching (PSM) method,neither 3DCRT nor IMRT yielded significant advantages in OS or PFS (P=0.971;P=0.658).However,IMRT tended to yield survival benefits in low-risk patients (P=0.125).Conclusions Both 3DCRT and IMRT yield relatively high OS rate in patients with stage Ⅱ/Ⅲ esophageal cancer.The prognosis model established in this investigation can properly predict the survival of patients.Low-risk patients tend to obtain survival benefits from IMRT.
