Purpose To investigate the relationship between HPV infection and p53,p16,EGFR expression and prognosis in patients with salivary adenoid cystic carcinoma (ACC).Methods Totally 76 cases of adenoid cystic carcinoma specimens were selected,PCR-reverse dot blot hybridization was used to detect infection of HPV and SP immunohistochemical method was adopted to detect the expression of p53,p16,EGFR,Cdc2 in tumor tissues.Clinical data were collected and all the patients were followed up.The Kaplan-Meier method was used to estimate median overall survival and the Log-rank test to compare survival curves.Cox regression model was used for multivariate analyses.Results Infection rate of HPV in adenoid cystic carcinoma tissues was 0(0/76).The expression rate of p53,p16,EGFR,Cdc2 protein in adenoid cystic carcinoma tissues were 76.3% (58/76),57.9% (44/76),60.5% (46/76) and 64.5% (49/76)respectively.There was no correlation of the expression of p53,p16,EGFR and Cdc2 with gender,age,tumor location,TNM stage and histological type of patient.Kaplan-Meier survival analysis showed that EGFR-positive patients had shorter median overall survival rate (OS) than the negative ones (x2 =19.111,P < 0.001).EGFR-positive patients had shorter median progression-free survival rate (PFS)than the negative ones (x2 =6.621,P < O.01).Cdc2 positive patients had shorter median OS than the negative ones (x2 =3.870,P < 0.05).Cdc2 positive patients had shorter median PFS than the negative ones (x2 =6.755,P <0.01).Cox regression analysis showed that expression of EGFR and Cdc2 was independent risk factors for the prognosis of patients with salivary gland ACC (relativerisk=13.417,13.075,P<0.001).Conclusion There is no HPV infection detected in adenoid cystic carcinoma tissues.p53,p16,EGFR and Cdc2 are positively expressed in most salivary adenoid cystic carcinoma,p16 is unsuitable as a surrogate for HPV infection status of patient with ACC.Expression of EGFR and Cdc2 is independent risk factors in the prognosis of patients with salivary gland ACC.For the EGFR or Cdc2 positive patients should be followed up closely.

Objective To observe the clinical efficacy of the combination of modification ofChaihu Jia Longgu MuliDecoction with psychological intervention in the treatment of post tumor depression.MethodsTotally 122 cases of post tumor depression were divided into treatment group and control group by simple numeration table random method, with 61 cases in each group. The treatment group was given modification ofChaihu Jia Longgu Muli Decoction orally, at the same time psychological intervention was given. The control group was given escitalopram oxalate tablets for 6 weeks. HAMD scale scores of the two groups were observed before and after treatment to evaluate the clinical efficacy. Changes in life quality of two groups were scored with SF-36 scale. The adverse reactions were also observed.ResultsAfter treatment, the HAMD score of treatment group was lower than control group (P<0.05). The total effective rate was 88.52% (54/61) in the treatment group and 72.13% (44/61) in the control group, with statistical significance (P<0.05). The scores of life quality of treatment group were higher than control group (P<0.05), and the incidence of adverse reactions was lower than control group (P<0.05).Conclusion Combination of modification ofChaihu Jia Longgu MuliDecoction with psychological intervention in the treatment of post tumor depression can significantly improve the depressive state and life quality of the patients with post tumor depression, which is better than the control group, without significant adverse reactions.

BACKGROUND:Electrospun porous nanofiber exhibits excellent properties and designability.It is an effective way to control the release of traditional Chinese medicine and improve the bioavailability to design an advanced drug delivery system,which has a broad application prospect. OBJECTIVE:To review the construction methods of the electrospinning drug delivery system of traditional Chinese medicine and its related research progress in the medical field. METHODS:The literature search was performed in CNKI,PubMed,and Web of Science databases with the search terms"electrospinning,traditional Chinese medicine,drug carrier,drug delivery system,tissue engineering,dressing"in both English and Chinese for articles published from 2013 to 2023.Finally,62 articles were included in this review. RESULTS AND CONCLUSION:(1)The key elements of the electrospinning drug delivery system of Chinese medicine preparation are substrate material,traditional Chinese medicine composition,and drug loading method.(2)The preparation of the electrospinning drug delivery system of Chinese medicine can be carried out according to the application scenario and therapeutic purpose.Firstly,the types of Chinese medicine are selected,then the polymer matrix and solution suitable for them are selected,and finally,the fiber structure is designed according to the drug release requirements and the appropriate drug loading method is adopted.(3)At present,the medicinal agents used are mainly plant Chinese medicine,and there is a lack of systematic research on animal and mineral Chinese medicine.(4)Blended drug loading is the most studied and applied drug loading method,and its drug release characteristics and adaptation scenarios are constantly expanded by optimizing the physicochemical properties of the solution and selecting the diversity of loaded substances.Multilayer fibers with different compositions and properties can be prepared by coaxial,multi-axis,and sequential electrospinning methods,which have broad development prospects.(5)The early application of the electrospinning drug delivery system of Chinese medicine focused on medical dressings according to the antibacterial and hemostatic functions.In recent years,it has been studied in the field of tissue engineering because some components of traditional Chinese medicine can promote cell adhesion,proliferation,and differentiation.(6)At present,the research mainly focuses on the characterization and optimization of loading materials,processes,physicochemical properties,and biological properties,but the research on the mechanism is less.Its clinical application has not been widespread;the adverse reactions in vivo and the interaction between its degradation behavior and drug release behavior are still unknown.(7)Future studies need to consider:We should expand the application of Chinese medicine by improving the physicochemical properties and increasing the purification of Chinese medicine extracts.We need to comprehensively study the therapeutic effects and application mechanisms of Chinese medicine,and clarify the interaction of degradation behavior and drug release behavior,to achieve a more perfect combination and application of Chinese medicine and electrospinning nanofibers under a more accurate mechanism.
