Objective To discuss the influence of psychological education on the resourcefulness of perioperative breast cancer patients. Methods Two hundred breast cancer patients from a first-class hospital in Fujian province were randomly assigned to the control group, in which routine care was done, and an intervention group, in which psychological education curriculum was employed at three stages on the basis of routine care. The resourcefulness scale was used in both two groups before and after the intervention to evaluate the score of individual and social resourcefulness and the total score of resourcefulness in these two groups. Results As to the control group, the score on individual resourcefulness and the total score on resourcefulness before and after the intervention had no significant differences (P>0.05), but the difference in the social resourcefulness scores before and after the intervention was statistically significant (P<0.05). The differences in the scores on the individual resourcefulness, social resourcefulness and the total score on resourcefulness in the intervention group before and after the intervention were all statistically different (P<0.001). What′s more, the scores of individual resourcefulness, social resourcefulness and the total score of resourcefulness between these two groups after the intervention were statistically different (P<0.001) as well. The scores of the intervention group were significantly higher than those of the control one. Conclusion The psychological education can significantly improve the resourcefulness level of perioperative breast cancer patients, which can help individuals to manage stress effectively.

Objective To investigate the clinical features and the prognosis after surgical treatment for hilar cholangiocarcinoma (HCC).Methods The surgical therapy and follow-up result were retrospectively analyzed on 98 cases of hilar cholangiocarcinoma admitted into our hospital from January 1995 to January 2005.Differences between groups were evaluated using Chi-square analysis or Student t-test according to the data type.Survival rate was calculated with Kaplan-Meier method,and using the log-rank test.Results Among 98 patients,83 patients underwent surgical treatment (radical resection in 33,palliative resection in 16,and nonresectional internal or external bile duct drainage in 34),15 patients underwent conservative therapy.The 1-,3-,5-year survival rates were 79％,42％,and 17％ in the resection group and 88％,54％,and 24％ in the radical resection group,respectively.The 1-,3-year survival rates were 55％,and 9％ in palliative resection group,respectively,and none of the patient survived for over 5 years.There were significant differences in the survival rate among the radical resection group and the palliative resection group (log-rank test,P ＜ 0.001).Conclusions Radical resection improves the prognosis of hilar cholangiocarcinoma.

The present study identified chemical constituents of Honghua Xiaoyao Tablet (HXT) and explored its biological connotation and characteristics on the premenstrual syndrome (PMS) treatment from the "disease-syndrome-symptom" association network. UHPLC-Q Exactive Orbitrap HRMS technology was applied to analyze the chemical constituents in HXT. According to the composition principles, the compatible herbs of HXT were divided into the Shugan Jieyu group, Huoxue Tiaojing group and Yiqi Jianpi group. The candidate targets of the corresponding prescriptions of HXT efficacy groups were collected from the Pharmmapper database and Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine (TCMIP) v2.0. The gene set related to the clinical symptoms included in Traditional Chinese and Western Medicine diagnosis and treatment standards were obtained from SoFDA, GeneCards, DisGeNET, MalaCards and literature published. The "HXT candidate targets-PMS (liver depression, Qi stagnation, and blood stasis syndrome) genes" network was constructed based on the gene interaction information, and further, the core network targets were screened out by topological characteristics of calculating network, and the functional exploration was carried out based on Kyoto Encyclopedia of Genes and Genomes (KEGG) for exploring the therapeutic advantages in PMS treatment of HXT efficacy groups, which were further verified experimentally in vitro. A total of 109 components from HXT were identified, including 20 components from Shugan Jieyu group enriched in the neurological system, estrogen regulation, and "immune-inflammation" related pathways, 77 components from Huoxue Tiaojing group enriched in the blood-circulation system, "immune-inflammation" and estrogen regulation related pathways and 30 components from Yiqi Jianpi group regulating immune inflammation, digestive system, and hormone levels. The biochemical indicator detection demonstrated that both the levels of 5-HT and DA in the hypothalamus tissues and the levels of E₂, NO, VEGF and RLN in the uterine tissues of PMS model rats were lower than those in controls, which the levels of OT, PROG, IL-6, IL-1β and TNF-α in the uterine tissues were increased in PMS group, which were all reversed by the administration of HXT, indicating that this prescription may regulate the synthesis and secretion of estrogen, intervene in neurotransmitter synthesis and signal transduction, reverse the imbalance of "immune-inflammation", and regulate digestive system function through various biological pathways, exerting the liver-smoothing, Qi-regulating, blood-activating and spleen-tonifying comprehensive effects, leading to alleviating the "neuroendocrine-endocrine-immune" system and blood-circulation disorders. The relevant results may provide a reference for clarifying the advantages and efficacy of HXT in treating PMS with liver stagnation, Qi stagnation, and blood stasis syndrome, and exploring its therapeutic advantages. The animal experiment of this study was approved by the Ethics Committee of the Institute of Chinese Materia Medica, China Academy of Chinese Medical Sciences (approval number: 2023B248).

Objective To explore the status quo of job stress and happiness in nurses of three grade A hospitals and mediation effects of hope between above two elements. Methods A cross-sectional survey was conducted. The Hope Status Scale, The Nurse's Job Stressor Scale, General Well-Being Schedule and self-designed demographic questionnaire were delivered to 1200 nurses from nine hospitals. Results The path analysis results showed that the direct effect of job stress on the subjective well-being was-0.193, the indirect effect was (-0.486) × 0.456=-0.222, the total effect of working pressure on the subjective well-being was-0.415, the indirect effect of total effect was 53.49％. want direct effect on subjective well-being of 0.456, job stress on the direct effect of hope for-0.486. Conclusion Hope to play an intermediary role between nurses' job stress and subjective happiness. In the process of trying to reduce nurses' job stress, we should make full use of the intermediary significance of hope to help nurses with low level of hope to build hope and improve their happiness level.

This study is to explore characteristic indexes in evaluation criteria for rat skin anaphylactoid test comparing skin blue spot OD values at the treated position and the control position in the same animal. Common contrast agents, traditional Chinese medicine injections and injections' active pharmaceutical ingredients or excipients in the existing clinical anaphylactoid reaction reports were taken as test drugs in the rat skin anaphylactoid test to define the K value: K > 2 represents positive anaphylactoid reaction, 1.2 ≤ K ≤ 2 represent doubtable anaphylactoid; K < 1.2 represents negative anaphylactoid reaction, which were taken as the criteria for evaluating anaphylactoid of tested drugs. The evaluation result and that for classic criteria were compared to study the applicability of K value. According to the comparison, K value, as the evaluation criteria in the rat skin anaphylactoid test, can more truly reflect the actual situation of skin aizen and minimize the error caused by animal individual factors. Compared with positive and negative two-level criteria for blue spot diameter, K value's positive, doubtable and negative three-level criteria are more objective and accurate. Therefore, K value can be used as the evaluation criteria in the rat skin anaphylactoid test.

BACKGROUND:Transfusion of bone marrow mesenchymal stem cells may become a novel and effective biological therapy for inflammatory bowel disease in clinical practice. Nevertheless, the oncological safety of the treatment is worrisome, and is a key to determine whether mesenchymal stem cells can be widely used in treatment of inflammatory bowel disease, and deserves further investigation. OBJECTIVE:To evaluate the therapeutic effect of bone marrow mesenchymal stem celltransfusion against inflammatory bowel disease in mouse models, and to clarify the effects of mesenchymal stem cells on tumorigenesis of inflammatory bowel disease. METHODS:Mouse model of colitis was established using Balb/c (H-2d) mice exposed to dextran sulfate sodium. Syngeneic bone marrow mesenchymal stem cells were transfused into mouse model through caudal vein. The therapeutic effect of mesenchymal stem cells was compared and observed, and pathological remission of colitis was evaluated. Mouse model of colitis-driven colon carcinogenesis was established using Balb/c (H-2d) mice exposed to dextran sulfate sodium and azoxymethane. Tumor formation within the murine colon was compared and observed after transfusion of mesenchymal stem cells. RESULTS AND CONCLUSION:In models of dextran sulfate sodium-induced colitis, weight loss and fecal occult blood were lessened in the bone marrow mesenchymal stem cellgroup compared with the phosphate buffered saline group. Histological damage score of colitis was less in the bone marrow mesenchymal stem cellgroup:mucosal structure of distal colon was almost intact under microscope, and there was smal area of epithelial defects and cryptal defects. Inflammatory cellinfiltration, proliferation of capil ary and smal vessels could be observed in mucosa and submucosa. Homing and colonization of mesenchymal stem cells in submucosa of inflamed colon could also be observed by in vivo tracing. In the dextran sulfate sodium/azoxymethane model of colitis-driven colon carcinogenesis, the number of intestinal tumors and tumor load were obviously less in the bone marrow mesenchymal stem cellgroup than in the control group. Results indicated that transfusion of bone marrow mesenchymal stem cells can apparently improve colitis lesions of mice with inflammatory bowel disease and inhibit carcinogenesis of colitis, which may provide theoretical support for the biological safety of mesenchymal stem cells transplantation for inflammatory bowel disease.
