Establishment and Evaluation of Rat Model for Chronic Obstructive Pulmonary Disease with Lung-spleen Qi Deficiency / 中国实验方剂学杂志

ObjectiveTo establish and evaluate a chronic obstructive pulmonary disease （COPD） model with lung-spleen qi deficiency. MethodA rat model mimicking COPD with lung-spleen qi deficiency was established by the combination of cigarette smoking and intratracheal instillation of lipopolysaccharide （LPS） along with gavage of Sennae Folium infusion. Forty male SPF-grade SD rats were randomly assigned to blank， model， and low- （L-FXY）， medium- （M-FXY）， and high-dose （H-FXY） Sennae Folium infusion groups. Other groups except the blank group were exposed to daily cigarette smoke， with LPS administrated via intratracheal instillation on the 1st and 14th days. On the 28th day of modeling， the L-FXY， M-FXY， and H-FXY groups were administrated with Sennae Folium infusion at 5， 10， and 20 g·kg-1， respectively， and at 4 ℃ for three weeks. The modeling lasted for 49 days. The general conditions （body mass， food intake， fecal water content， and anal temperature） and behaviors （grip strength test and tail suspension test） of rats in different groups were examined. The lung function， lung histopathology， D-xylose， amylase， and gastrin levels in the serum， interleukin（IL）-1β and IL-6 levels in the alveolar lavage fluid， levels of T-lymphocyte subsets （CD4+， CD8+， and CD4+/CD8+） in the peripheral blood， and thymus and spleen indices were measured. ResultTwo rats died in the H-FXY group. Compared with the blank group， both the M-FXY and H-FXY groups exhibited reduced body mass and food intake （P<0.01） and increased fecal water content （P<0.01）. The anal temperature in the H-FXY group was lower than that in the blank group （P<0.01）. The grip strength decreased in the modeling groups compared with the blank group （P<0.01）， and the duration of immobility in the tail suspension test increased in the M-FXY and H-FXY groups （P<0.05， P<0.01）. Compared with the blank group， the modeling groups showed reduced 0.3 second forced expiratory volume （FEV0.3）， FEV0.3/forced vital capacity （FVC）（P<0.01）， thickening of bronchial walls， proliferation of goblet cells， and the presence of emphysematous changes. In terms of gastrointestinal function， the M-FXY and H-FXY groups had lower levels of D-xylose， gastrin， and α-amylase than the blank group （P<0.01）. Regarding the immune and inflammatory indices， the M-FXY and H-FXY groups showed lower thymus and spleen indices than the blank group （P<0.01）. Compared with the blank group， the modeling groups presented lowered CD4+ level （P<0.01） and CD4+/CD8+ ratio （P<0.05， P<0.01） in the peripheral blood and elevated levels of IL-1β and IL-6 in the alveolar lavage fluid （P<0.01） than the blank group. ConclusionA model of COPD with lung-spleen Qi deficiency was established through the combination of daily cigarette smoke， intratracheal instillation with LPS， and gavage of Sennae Folium infusion. The comprehensive evaluation results suggested medium-dose （10 g·kg-1） Sennae Folium infusion for gavage during the modeling of COPD with lung-spleen Qi deficiency.

Pathogenic mechanism and research progress of adipocytokines in endometrial cancer / 中国临床药理学与治疗学

Endometrial carcinoma (EC) is one of the most common gynecologic tumors, and its incidence and mortality are increasing.The prognosis is usually favorable when the disease is diagnosed at an early stage. However, the prognosis for patients with recurrence and metastasis is relatively poor. As one of the risk factors for EC, the complex and widespread oncogenic role of obesity in EC has been validated, then the oncogenic and pro-carcinogenic mechanisms of adipocytokines secreted by adipose tissue in EC have attracted continuous attention. This review highly summarizes and concludes the previous relevant literature on the role of adipocytokines in endometrial cancer and the progress of research，and elucidates the correlation between adipocytokines and the occurrence risk, stage grading, and long-term prognosis of EC, as well as their signaling pathways and mechanisms of action in the development of EC. All this information will likely contribute to the development of novel molecular markers in EC, the discovery of new therapeutic targets, and the study of related targeted drugs, which may in turn break the current dilemma of early screening, early diagnosis, and treatment of recurrent and metastatic patients in EC in the future, resulting in an improvement of the long-term prognosis of patients with EC.

Mobile-health information searching behaviors and its influencing factors for patients with cancer / 中华行为医学与脑科学杂志

Objective:To explore the behavior and influencing factors of mobile health (m-Health) information searching among patients with cancer, aiming to provide evidence for the provision of medical health information.Methods:A cross-sectional survey was conducted.A total of 535 patients with cancer were recruited from a cancer hospital in Zhejiang Province from September to December 2017.Measurement tools included the demographic information questionnaire, mobile health information search behavior questionnaire, mobile health information search environment questionnaire, cancer needs questionnaires-short form and ehealth literacy scale.SPSS 26.0 was used for descriptive statistical analysis, one-way analysis of variance, Pearson correlation analysis and multiple linear regression analysis.Results:The total score of mobile health information search behavior of cancer patients was (60.84±9.60), and 66.5% of participants reported that they "never" or "occasionally" searched health information via mobile.The total score of information needs was (80.99±27.86), electronic health literacy was (26.54±7.85), mobile health information search environment was (8.00±2.86). m-Health information search behavior was positively correlated with information needs ( r=0.251, P<0.01), ehealth literacy ( r=0.538, P<0.01), and m-Health information search environment ( r=0.267, P<0.01). The stepwise regression analysis revealed that the place of residence, working status, income level, ehealth literacy, mobile health information search environment and information needs were statistically significant associated with the m-Health information searching behavior among cancer patients, which accounted for 39.3% of the total variance ( F=12.151, P<0.01). Compared with patients living in the central cities, those living in the small and medium-sized cities( β=0.092, P=0.031) had higher score in m-Health information behavior.Compared with patients working on normal schedule, those took sick days ( β=0.156, P=0.017) and working fewer hours ( β=0.138, P=0.002) had higher score m-Health information behavior.Compared with patients with monthly income of 1 000-3 000 yuan ( β=-0.194, P=0.002), those with monthly income less than 1 000 yuan had higher score in m-Health information behavior.The ehealth literacy ( β=0.425, P=0.000), mobile health information search environment ( β=0.179, P=0.000) and information needs ( β=0.091, P=0.027) were positive influencing factors of m-Health information search behavior. Conclusion:Patients with cancer did not report high m-Health information search behavior.Place of residence, working status, income level, ehealth literacy, m-Health information search environment and information demand were the influencing factors of m-Health information search behavior among patients with cancer.

CT measured abdominal fat correlated parameters for diagnosis of coronary artery disease / 中国介入影像与治疗学

Objective: To observe the value of CT measured abdominal fat correlated parameters for diagnosis of coronary artery disease (CAD). Methods: Totally 211 patients with suspected CAD who underwent coronary angiography and abdominal CT plain scan within 30 days were retrospectively analyzed. The risk factors of CAD were analyzed. ROC curve was used to observe the diagnostic efficacy of each risk factor alone and their combination for CAD. Results: Among 211 cases, CAD was definitely diagnosed with coronary angiography in 112 cases, while 99 cases were found non-CAD. The single factor analysis showed that age, gender, smoking, diabetes mellitus, hypertension, high density lipoprotein-cholesterol (HDL-C), visceral adipose tissue (VAT) area, subcutaneous adipose tissue (SAT) area and VAT area/SAT area (VAT/SAT) were significantly different between CAD and non-CAD patients (all P0.05). Multivariable Logistic regression analysis demonstrated that age, smoking, diabetes mellitus and VAT/SAT were independent risks of CAD (all P<0.01). ROC curves showed the AUC of diagnosing CAD in age, smoking, diabetes mellitus and VAT/SAT was 0.67, 0.61, 0.62 and 0.73, respectively. The AUC of the combination of the above four risk factors was 0.80, higher than that of any single risk factor (all P<0.05). Conclusion: CT measured abdominal fat correlated parameters could be used for diagnosing CAD.

The role of traditional Chinese medicine characteristic lung rehabilitation for treatment of patients with chronic obstructive pulmonary disease and syndrome of lung and kidney qi deficiency at steady state / 中国中西医结合急救杂志

Objective To observe the clinical effect of traditional Chinese medicine (TCM) characteristic lung rehabilitation in treatment of patients with chronic obstructive pulmonary disease (COPD) and TCM syndrome of lung and kidney qi deficiency at stable period. Methods Sixty patients with stable COPD and lung and kidney qi deficiency syndrome admitted to the First Affiliated Hospital of Anhui University of Chinese Medicine from June to August 2017 were enrolled, and they were divided into routine treatment group and lung rehabilitation treatment group according to the random number table method, each group 30 cases. The routine treatment group was given Seretide (serevent/futicasone) dry powderi nhalation therapy; on the basis of therapy in the routine treatment group, the lung rehabilitation treatment group was treated with TCM characteristic lung rehabilitation technology (acupoint application + Chinese medicine ionic induction + oral administration of Chinese medicine Liuweibuqi granules, delivery at appropriate intervals); both groups were treated for 2 months. The changes of TCM syndrome score, western medicine symptom score, the times of acute exacerbation of COPD, COPD assessment test (CAT) score, lung function indexes: forced expiratory volume in one second (FEV1), FEV1/forced vital capacity (FVC) were observed before and after treatment in two groups. Results After treatment, TCM syndrome score, western medicine symptom score, CAT score, and after treatment the times of acute exacerbation of COPD in both groups were significantly lower than those before treatment, and the above indexes in the lung rehabilitation treatment group were markedly lower than those in routine treatment group [TCM syndrome score:11.93±1.80 vs. 14.27±2.88, western medicine symptom score: 14.20±2.75 vs. 11.93±4.23, CAT score: 14.87±2.60 vs. 16.23±4.39, the times of acute exacerbation of COPD (times): 0.63±0.49 vs. 0.95±0.83, all P < 0.05]. The improvement of FEV1 in the two groups was not significant; but FEV1/FVC in lung rehabilitation treatment group was obviously higher than that before treatment, FEV1/FVC in lung rehabilitation treatment group was significantly higher than that in the routine treatment group [(57.93±7.27)% vs. (52.49±6.61)%, P < 0.05]. Conclusion The application of TCM characteristic lung rehabilitation in the treatment of COPD patients with stable lung and kidney qi deficiency syndrome based on bronchodilators and glucocorticoids can reduce the number of acute exacerbation, improve the patients' clinical symptoms and living quality, but the improvement of lung function is not significant.
