Objective To explore the procedure options in the treatment for acute plasma cell mastitis with minimal compromise to breast appearance. Methods The clinical data of 19 cases diagnosed as acute plasma cell mastitis from 2007 to 2010 were analyzed retrospectively. All the patients were adopted the same protocol as the combination of traditional Chinese medicine，abscess drainage at the proper moment，and the excision of focal mass after the acute inflammatory response diminish. Results The duration from taking traditional Chinese medicine to lumpectomy in all the patients were from 63 d to 97d，and the average time was 78d. Seven cases were treated with antibiotic before lumpectomy and 12 cases were treated with abscess drainage，and all the patients were cured satisfactorily. All the patients were followed up for 24-48 months with an average 36 months， there was no recurrence，and the shape of the treated breast remained consistent with the contralateral side，with the natural shape and smooth skin，and an undetectable thready mammary areola incision left. Conclusion The combination of traditional Chinese and Western medicine could treat acute plasma cell mastitis efficiently and with an advantage of minimal compromise to breast appearance.
Influenza A is an acute infectious respiratory disease caused by influenza A virus, with typical signs and symptoms of upper and / or lower respiratory tract involvement, and symptoms of systemic disease such as fever, headache, myalgia and fatigue. Although it is a self-limited disease in the general population, it is associated with increased morbidity and mortality in some high-risk populations and often leads serious complications, such as severe acute lung injury, acute respiratory distress syndrome, as well as other extrapulmonary injuries. The exploration of the mechanisms of lung injury caused by influenza A infection could be helpful to understand the pathogenic mechanisms of other viral pneumonias, such as coronavirus disease 2019.
ObjectiveTo elucidate the latest research progress of Yes-associated protein (YAP) / transcriptional coactivator with PDZ-binding motif (TAZ) in regulating tumor drug resistance. MethodThe relevant literature on YAP/TAZ in regulating tumor cell chemotherapy, immunotherapy, and targeted therapy resistance was reviewed and summarized in the databases such as PubMed, CNKI, and so on. ResultsThe YAP/TAZ was involved in the resistance regulation of chemotherapy, immunotherapy, and targeted therapy in various human tumors. The YAP/TAZ could interact with various proteins to induce the occurrence of tumor resistance. The imbalance of YAP/TAZ signaling might lead to an important mechanism of tumor cell resistance. ConclusionsThere is a close relation between YAP/TAZ and tumor cell resistance. Studying the mechanism of YAP/TAZ regulating tumor resistance can provide new strategies and targets for addressing tumor resistance.

Real-world studies (RWSs) data are based on real medical scenes and reflect clinical facts. Besides, RWSs adapts to the characteristics of therapeutic principles of traditional Chinese medicine and the medical reality of the combination of Western and traditional Chinese medicine, which makes the safety assessment of herb-drug interaction more efficient and economical. During RWSs, more attention should be paid on the validity and reliability of data, especially the standardization of the data collection process and its contents. The safety assessment of herb-drug interaction will combine the methods of active surveillance study, big data analysis, and be based on precision medicine in the future
Objective To investigate the structure characteristics， functions， and research progress of Notch signaling pathway in digestive tumors. Methods The related literatures about the molecular genetic mechanism of Notch signaling pathway were reviewed. Results The Notch signaling pathway plays an important role not only in normal cells’ growth， differentiation， proliferation， and apoptosis but also in a variety of tumors’ occurrence and development. Conclusion The reasonable regulation to Notch signaling pathway may open up new ways to the treatment of the tumor.
【Abstract】 Objective To evaluate the relationship between multiple tumor biomarkers and idiopathic pulmonary fibrosis ( IPF) , and analyze the prognostic value of these biomarkers in IPF. Methods Clinical data of 43 confirmed IPF patients with no evidence of malignant disaeses, admitted in Peking Union Medical College Hospital between January 2000 and June 2010, were retrospectively analyzed. All IPF patients had detected serum alpha fetoprotein ( AFP) , cancer antigen 50 ( CA50) , cancer antigen 24-2( CA24-2) , carcinoembryonic antigen ( CEA) , carbohydrate antigen 19-9 ( CA19-9) , cancer antigen 125( CA125) , cancer antigen 15-3 ( CA15-3) , tissue polypeptide antigen ( TPA) , neuron specific enolase( NSE) , and cytokeratin-19-fragment ( Cyfra211) . Results The serum levels of CEA, CA19-9, CA125,CA15-3, and TPA were obviously higher than normal range, while the serum levels of AFP, CA50, CA24-2,NSE, and Cyfra211 were within normal range. Neither tumor biomarkers had correlation with 6-minute walk distance, FVC% pred, TLC% pred, DLCO/VA, PaO2 , PaO2 /FiO2 , P( A-a) O2 , BALF cell differentiation counting,or CD4 /CD8. The patients with increased CA19-9 level had shorter survival time than those with normal CA19-9 level ( P lt; 0. 05) . There was no significant difference in survival time between the patients with increased CEA/TPA levels and those with normal CEA/TPA levels( P gt;0. 05) , neither between the patients with glucocorticoid treatment and those with non-glucocorticoid treatment ( P gt; 0. 05) . Conclusions Multiple tumor biomarkers, especially CA19-9, increase in IPF patients. The degrees of those increases arenot associated with the severity of disease, but closely relate to prognosis, and may also indicate the progression. The increases of multiple tumor biomarkers may be a sign of poor prognosis of IPF with no evidence of malignant disaeses.
Objective To investigate the role of IFN-γ in suppressing bleomycin-induced pulmonary fibrosis in rats.Methods Seventy-five SD rats were randomly divided into five groups (15 rats in each group)，ie.a normal group，a bleomycin-induced pulmonary fibrosis model group，a dexamethasone-treated group，a high-dose IFN-γ-treated group (150 000 U/kg) and a low-dose IFN-γ-treated group (50 000 U/kg).Five rats in each group were randomly killed in 7th day，14th day and 28th day after relative treatment respectively，and lung tissue samples were harvested for histopathology study.HE and Masson staining were used to determine the extent of alveolus inflammation and pulmonary fibrosis respectively.Histoimmunochemical method were adapted to determine protein levels of TGF-β1，CTGF，type Ⅰcollagen and type Ⅲ collagen in pulmonary tissues.Results Histopathological study showed that treatment with either dexamethasone or IFN-γ (both high dose and low dose) remarkably meliorated the extent of alveolus inflammation and suppressed pulmonary fibrosis (compared with model group，all Plt;0.05).Histoimmunochemical study suggested that both dexamethasone and IFN-γ could inhibit the expression of TGF-β1，CTGF，type Ⅰand type Ⅲ collagen (compared with model group，all Plt;0.05)，and the suppression of TGF-β1，type Ⅰand type Ⅲ collagen expression was more obvious in high-dose IFN-γ-treated group than those in low-dose group (Plt;0.05).Conclusions INF-γ possesses apparent anti-fibrosis effect that is similar to dexamethasone but with less side effect.Such effect may resulted from reduced production of type Ⅰand type Ⅲ collagen through expression inhibition of cytokines such as TGF-β1 and CTGF.
ObjectiveTo explore the application value of multidisciplinary collaborative team (MDT) model in retroperitoneal tumors involving large vessels.MethodsThree cases of retroperitoneal tumors involving great vessels admitted to Xiang’an Hospital of Xiamen University in 2019 were retrospectively analyzed. With the support of 3D visual reconstruction and virtual reality (VR) technology, we performed MDT discussion and three cases received treatment of surgery, intervention, and targeted therapy.ResultsCase 1 was discussed by MDT and concluded that, based on CT examination, 3D reconstruction, and VR virtual image results, the tumor on the right side was determined to be completely resectable. The left tumor was judged to be unresectable, and the proposed treatment plan was right metastatic tumor resection + left metastatic tumor radiofrequency ablation. After surgery case 1 had been followed up for 6 months. The symptoms of diarrhea were significantly improved. CT reexamination showed that liver lesions and left retroperitoneal lesions were the same size and the condition was stable. After discussion by MDT, radiofrequency ablation around the tumor was proposed for case 2. This case was followed up for 3 months after surgery, and CT reexamination showed no new lesion in retroperitoneum. After MDT discussion, we concluded that arteriovenous fistula of case 3 had no indications for surgery, and proposed interventional combined with targeted therapy. After treatment, the tumor was found to be smaller after reexamination in 8 months than before treatment, and the efficacy was evaluated as partial remission. The follow-up was continued.ConclusionThe future development trend of retroperitoneal tumor therapy involving great vessels is to evaluate each patient’s condition under the MDT mode by using 3D visual reconstruction and VR technology, and to formulate the individualized treatment plan of operation combined with other treatments.
