Dingzhi Xiaowan is a widely used traditional Chinese medicine in treating depression, which is a similar formula of Kaixinsan. In this research, a rapid ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS(E)) method was established to analyze the metabolites of Dingzhi Xiaowan in depressive model rat plasma, bile, urine and feces. After we established Chronic unpredictable mild stress (CUMS) model rats and orally administrated Dingzhi Xiaowan, rat plasma, bile, urine and feces samples were collected and prepared. Using Waters Cortects UPLC C18 column (2.1 mm x 50 mm, 1.6 μm), acetonitrile-0.1% formic acid mobile phase gradient, these samples were analyzed and 33 metabolites of nine bioactive compounds were detected and tentatively identified by Metabolynx. Among the 33 metabolites, three metabolites were identified from plasma sample, three came from bile sample, and 27 metabolites were identified from urine and feces samples. This approach provided a rapid method for characterizing the metabolites of Dingzhi Xiaowan and gave the truly active structures and the action mechanism of their antidepressant effects.

OBJECTIVETo develop quality of life questionnaire of Chinese medicine for postoperative patients with colorectal cancer (QLQ-CMPPCC), thus comprehensively and objectively evaluating the clinical efficacy of Chinese medicine and pharmacy in treating postoperative patients with colorectal cancer (CC).

METHODSThe theoretical structure model of the questionnaire was addressed in combined with basic theories of Chinese medicine according to the principle of WHO quality of life (QOL). The primary questionnaire was developed using methods of structuralization policy making after we extensively retrieve various universal and specific questionnaires for CC cancer patients at home and abroad. The 205 CC patients were tested by questionnaire. The items were screened using experts grading method, item selection analysis, dispersion trends of standard deviation, t-test, correlation coefficient method, factor analysis,and Cronbach's alpha.

RESULTSThe QLQ-CMPPCC was developed containing four domains of physical, psychological, independence, and social functions, involving 20 aspects and 54 items. Of them, non-fistula patients answered 43 items and fistula patients answered 46 items. One item covered the general QOL evaluation.

CONCLUSIONSQLQ-CMPPCC showed Chinese medical features. It comprehensively reflected the connotation of QOL for postoperative CC patients. It could be taken as a tool for evaluating Chinese medical efficacy for postoperative CC patients.

BACKGROUND: Primary pulmonary malignancies (PPMs) and non-pulmonary malignancies (PNPMs) may result in airway stenosis requiring stenting. This study aimed to compare and evaluate the clinical features and stent placement outcomes of airway stenosis caused by PPMs and PNPMs. METHODS: A total of 141 patients with malignant airway stenosis who underwent Micro-Tech stent placements between January 2004 and October 2017 at Department of Respiratory Medicine, Beijing Tian Tan Hospital, Capital Medical University were divided into PPM (n = 100) and PNPM groups (n = 41). Patients' clinical features and stent placement outcomes were collected and analyzed. Chi-square test was used to compare the categorical variables, while independent- or paired-sample t test was used to compare the continuous variables. RESULTS: There were no significant differences in age, sex, treatment history, respiratory symptoms, and incidence of obstructive pneumonia between groups. Multiple airway involvement (63.0% vs. 31.7%; χ = 11.459, P = 0.001) and atelectasis (17.0% vs. 2.4%; χ = 5.536, P = 0.019) were more common in the PPM group, while extraluminal obstruction (24.4% vs. 6.0%; χ = 8.033, P = 0.005) was more common in the PNPM group. Before stenting, the American Thoracic Society Dyspnea Index (ADI) and Karnofsky Performance Scale (KPS) scores showed no significant differences between groups (all P > 0.05). After stenting, a satisfactory rate of symptom improvement was achieved in both groups (98.0% and 100.0% in the PPM and PNPM groups, respectively; χ = 0.016, P = 0.898); ADI and KPS scores, which showed no significant differences between groups (all P > 0.05), were significantly improved in each group (all P < 0.001). Complications after stenting could be effectively managed using bronchoscopic procedures. CONCLUSIONS Among cases of malignant airway stenosis requiring stenting, those caused by PPM are more likely to involve multiple airways and are associated with atelectasis, while those caused by PNPM are more likely to cause extraluminal obstruction. Micro-Tech stent placement has the same immediate effect in terms of improvement in respiratory symptoms and performance status for both malignant airway stenosis caused by PPM and that caused by PNPM.

To study the anti-radiation effect and mechanism of ethanol extracts from Spatholobus suberectus and its active component catechin, ICR mice were exposed to 6Gy irradiation and randomly divided into normal group, model group, positive control group (amifostine, 43.6 mg•kg⁻¹, iv 30 min before irradiation), SSD group (10, 20, 40 g•kg⁻¹) and catechin group (50, 100, 200 mg•kg⁻¹). The mice were administered the appropriate drugs once a day after irradiation for 28 consecutive days. Blood samples were collected from the tail end and the number of peripheral blood cells was counted before irradiation and on day 1, 3, 7, 14, 21 and 28 using a microcell counter. Changes of thymus and spleen index of mice on day 7 were observed. The serum SOD, GSH-Px activity and MDA level were detected by the colorimetric method. The colony forming ability of bone marrow hematopoietic progenitor cells on day 7 was detected by semi solid culture method. The HE staining was adopted to observe the pathological changes. The apoptosis of bone marrow cells was detected by flow cytometry. The expression of cleaved caspase-3 and Bax of bone marrow cells were measured separately by western-blotting and immunohistochemistry method. SSD and catechin can both significantly revert the irradiated-induced decline in hematological parameters (RBC, WBC, PLT, Hb), improve thymus and spleen index, significantly enhance serum SOD and GSH-Px activity and decrease the MDA level. The proliferation and differentiation of hematopoietic progenitor cells in bone marrow were promoted, the apoptosis of bone marrow cells was significantly up-regulated and the expression of cleaved caspase-3 and Bax was significantly reduced in SSD and catechin group. SSD and catechin have significant anti-radiation effect and its mechanism may be related to hematopoietic promoting, antioxidant and anti-apoptotic effects.

Objective The role of planned neoadjuvant radiotherapy or chemoradiotherapy in the non?radical resection of esophageal squamous cell carcinoma was unclear. The study aimed to evaluate their therapeutic effect and analyze the prognostic factors. Methods We retrospectively analyzed the clinical data of locally advanced esophageal squamous cell carcinoma who received neoadjuvant radio therapy ( 33 patients) and concurrent chemoradiotherapy (119 patients) from January 2004 to December 2016 in our single?institution database.The survival rates were calculated by Kaplan?Meier method. The prognostic factors were analyzed by using Log rank test and Cox proportional hazards model. Results The median follow?up was 29.8 months. One hundred and one patients survived more than 3 years. The rates of overall survival (OS) and disease?free survival ( DFS) at 3 years were 63.9% and 55.6%, respectively.The rates of complete, partial and minimal pathological response of the primary tumor were 50.3%, 38.4%, 11.3%, the corresponding 3?year OS were 75.5%, 57.4%, 27.3%( P＜0.001) and 3?year DFS were 72.0%, 44.7%, 17.6%(P＜0.001), respectively.The postoperative lymph node metastasis rate was 27.0%. The 3?year OS and DFS of the lymph node positive group was 45.6% and 32.8%, significantly lower than 70.8% and 63.7%of the negative group (both P＜0.001).The 3?year OS and DFS of pathologic stage Ⅰ,Ⅱ,ⅢA,ⅢB andⅥ A were 76.2%, 57.4%, 64.7%, 35.0%, 33.3%( P＜0.001) and 70.1%, 49.3%, 41.2%, 22.1%, 33.3%(P＜0.001), respectively.The operation?related mortality was 3.3%. Multivariate analysis showed that chest pain, postoperative respiratory failure, pathological differentiation, more than 15 lymph node dissection and ypTNM stage were the independent prognostic factors of OS ( P＜0.05 for all). Conclusions The planned neoadjuvant radiotherapy or chemoradiotherapy for the non?radical resection of advanced esophageal squamous cell carcinoma could result in favorable survival. The chest pain, postoperative respiratory failure, pathological differentiation, the number of lymph node resection and ypTNM stage are the independent prognostic factors of the prognosis of these patients.
