Objective To evaluate the effectiveness of intern doctor training by 360 degree evaluation scale and to provide references for formulating targeted training plan. Methods A 360-degree evaluation scale with 6 subscales(Attendings, Peers, Nurse, Patients, Directors and Students) was employed to measure the status quo of medical education , represented by professional ethics and communication skills, among 129 intern doctors in medical clinical college. Cronbach's alpha was used to evaluate the reliability of the scale,one-way ANOVA was used to compare the difference of score among different scorers,and t test and Mann-Whitney test were employed to compare scores be-tween male group and female group, 5-year class and 8-year class (The significance level was set at P<0.05). Results Cronbach' α coefficients were 0.878, 0.948, 0.914, 0.908, and 0.934 for six sub-scales and 0.964 for the general scale. There were significant differences in evaluation scale scores a-mong differ-ent evaluators(P<0.01). After being adjusted by weight index, the average scores of pro-fessional ethics and communication ability & interpersonal relationship were ( 92 . 52 ± 8 . 09 ) and (93.32±8.67) respectively. No differences was observed between male and female, 5-year class and 8-year class(P>0.05). Conclusions 360 degree evaluation scale has reasonable reliability and it can provide valuable references for future similar survey in China. Meanwhile, intern doctors exhibit rela-tively good performances in professional ethics and communication ability & interpersonal relationship in the present study.

Objective To optimize the extraction process and improve the quality of Toufu irrigation.Methods Matrine assay was selected to be the indicator for the extraction efficacy.Orthogonal test was used to determine the optimal water a-mount,extraction time and extraction frequency.Results The best extraction process was to extract 90 minutes twice with the water amount 8 times of the dry herbal material by weight.Conclusion This process is feasible and repeatable.It can be used for the quality control of the preparation.

Desmoplastic tumors have an abundance of stromal cells and the extracellular matrix which usually result in therapeutic resistance. Current treatment prescriptions for desmoplastic tumors are usually not sufficient to eliminate the malignancy. Recently, through modulating cancer-associated fibroblasts (CAFs) which are the most abundant cell type among all stromal cells, natural products have improved chemotherapies and the delivery of nanomedicines to the tumor cells, showing promising ability to improve treatment effects on desmoplastic tumors. In this review, we discussed the latest advances in inhibiting desmoplastic tumors by modeling CAFs using natural products, highlighting the potential therapeutic abilities of natural products in targeting CAFs for cancer treatment.

Brain tumor incidence shows an upward trend in recent years; brain tumors account for 5% of adult tumors, while in children, this figure has increased to 70%. Moreover, 20%-30% of malignant tumors will eventually metastasize into the brain. Both benign and malignant tumors can cause an increase in intracranial pressure and brain tissue compression, leading to central nervous system (CNS) damage which endangers the patients' lives. Despite the many approaches to treating brain tumors and the progress that has been made, only modest gains in survival time of brain tumor patients have been achieved. At present, chemotherapy is the treatment of choice for many cancers, but the special structure of the blood-brain barrier (BBB) limits most chemotherapeutic agents from passing through the BBB and penetrating into tumors in the brain. The BBB microenvironment contains numerous cell types, including endothelial cells, astrocytes, peripheral cells and microglia, and extracellular matrix (ECM). Many chemical components of natural products are reported to regulate the BBB microenvironment near brain tumors and assist in their treatment. This review focuses on the composition and function of the BBB microenvironment under both physiological and pathological conditions, and the current research progress in regulating the BBB microenvironment by natural products to promote the treatment of brain tumors.
