Objective To observe the effect of Rhizome Atractylodis Macrocephalae (RAM) on electrogastric arrhythmia in rats and its mechanisms. Methods A total of 30 Wistar rats were randomly divided into 3 groups: control group, model group and RAM plus model group. The frequency of slow wave(FSW), coefficient of variation(CV) and abnormal rhythm index(ARI) were recorded and analyzed by computer. The substance P(SP), vasoactive intestinal peptide(VIP) and nitric oxide synthase(NOS) nerves in antral myenteric plexus were observed by immunohistochemical staining. Results Compared with those of the control group, the CV and ARI in model group markedly increased( P 0.05). The denites of SP nerves markedly decreased( P 0.05). Conclusion RAM has regulative effect on the electrogastric arrhythmia in rats and the mechanisms may be related with the increased SP nerves and decreased VIP and NOS nerves in antral myenteric plexus.

Objective To investigate the changes in gastrointestinal motility and cholinergic nervous system in the gastric antrum and intestine of rats with cirrhosis. Methods 20 Wistar rats were randomly divided into control group and cirrhosis model group. The changes in gastrointestinal motility of rats were assessed by Dextran blue-2000 as an indicator; the cholinergic nerves in antro-jejunal myoenteric plexus were observed with acetylcholinesterase histochemical staining and analysed with a computer. Results Compare with control group, the gastrointestinal motility of rats was markedly retarded (P

To study the effect of pericarpium arecae on gastric electro arrhythmia in rats and its mechanisms, 30 Wistars were randomly divided into 3 groups: control group, model group and pericarpium arecae plus model group.The frequency of slow wave, coefficient of variation (CV) and abnormal rhythm index (ARI) were recorded and analyzed by computer, meanwhile the cholinergic and nitrigic nerves in antral myoenteric plexus were observed with histochemical staining. The results showed that, compared with control group, the CV and ARI in model group markedly increased ( P 0 05) after treatment with pericarpium arecae; the density of cholinergic nerves markedly decreased( P 0 05) after treatment with pericarpium arecae. It suggested that pericarpium arecae has regulative effect on the gastric electro arrhythmia in rats, and the increased cholinergic nerves and decreased nitrigic nerves in antral myoenteric plexus may be its underlying mechanisms.

Objective　To study the mechanisms of Pericarpium Arecae. Methods　A total of Wistar rats were randomly divided into Pericarpium Arecae group and control group, Pericarpium Arecae decoction or distilled water were given respectively. Changes of gastrointestinal motility rats were assayed by Dextran blue-2000 after 1 and 6 hours. The distributions of SP and VIP in antrum and jejunum were investigated by immunohistochemistry assay. Results　The gastrointestinal motility of rats was markedly enhanced (P<0.01 or P<0.05). The expressions of SP increased significantly (P<0.01 or P<0.05) and the expressions of VIP decreased significantly (P<0.01 or P<0.05) in antrum and jejunum of rats at 1 and 6 h after Pericarpium Arecae decoction was given. The changes were more obvious at 1 h than at 6 h. Conclusion　The kinetogenic effect of Pericarpium Arecae is closely correlated to the increase of SP expression and the decrease of VIP expression in gastrointestinal tract.

Breast cancer is one of the most common cancers in China. With increasing of the incidence and mortality, the harm to women is becoming much serious. Estrogen positive patients need to take 5-10 years′ endocrine drugs to prolong survival and prevent recurrence. Endocrine therapy has become one of the most common and effective methods in the treatment of breast cancer. In order to achieve the desired effect of cancer treatment, reduce cancer metastasis and recurrence rate, good compliance is essential. In conclusion, this review summarizes the evaluation of compliance, various evaluation tools and their use.

Objective To investigate the role of Wnt/β-catenin pathway in regulating allergic airway inflammation in asthmatic mice.Methods We induced dendritic cells (DCs) from bone marrow of BALB/c mice,and then treated the cells with LiCl and PKF118-310,separately.We observed the morphological features of DCs under light microscope.Mixed lymphocyte reaction (MLR) was used to observe the functional changes of DCs.Western blot was used to detect the expressions of GSK-3β and β-catenin at the protein level.We established a mouse asthma model by using ovalbumin (OVA),and then treated these mice with LiCl and PKF118-310.The total number of cells and eosinophil percentage in BALF were determined.The lungs of mice were observed by HE staining to evaluate the degree of allergic inflammation.The cytokines in BALF and spleen cells supernatant were assayed by enzyme-linked immunoassay (ELISA),and the total IgE in the serum was also measured by ELISA.The protein expression levels of GSK-3β and β-catenin in lung tissue were assayed by Western blot.Results ① The DCs treated with LiCl promoted the proliferation of allogeneic T lymphocytes in MLR more weakly than those treated with PKF118-310 (P＜0.01).② The GSK-3β protein expression level of DCs treated with LiCl was significantly lower than DCs treated with PKF118-310.In contrast,the β-catenin protein expression of DCs treated with LiCl was higher than that of DCs treated with PKF118-310 (P ＜ 0.01).③ The total number of cells and eosinophil percentage in BALF were significantly increased in the experimental group compared with those in the control group (P＜0.01).There was also a significant difference between LiCl group and PKF118-310 group (P＜0.01).④ In the three experimental groups,the severity of inflammation in the lungs of LiCl group was weaker than that in PKF118-310 group (P＜0.05).⑤ Compared with that in the normal control group,IL-4 in BALF and spleen cell culture supernatant of the experimental group was significantly higher while IFN-γ was the opposite (P＜0.01).LiCl group had the lowest level of IL-4 and the highest level of IFN-γ;PKF groups was the opposite (P＜0.05).⑥ The total IgE in serum was significantly increased in the experimental group compared with the control group (P＜0.01).There was also a significant difference between LiCl group and PKF118-310 group (P＜0.05).⑦ GSK-3β protein expression was significantly lower in LiCl group than in PKF118-310 group (P＜0.05),while β-catenin protein expression was significantly higher in LiCl group than in PKF118-310 group (P＜0.05).Conclusion LiCl and PKF118-310 can affect the severity of asthma by regulating Wnt/β-catenin signal pathway and the expressions of GSK-3β andβ-catenin protein,which provides a new direction for asthma treatment.

Objective: To explore the characteristics and relationship between physical activity and self-efficacy of college students during the COVID-19 epidemic, so as to provide evidence for the orderly development of physical education and curriculum reform of college students after their return to school. Methods: A total of 6 227 college students were collected from 8 districts of China by using convenient sampling method and snowball sampling method, and the physical activity and self-efficacy of all participants were assessed used by the International Physical Activity Questionnaire Short Form (IPAQ-S) and the General Self-Efficacy Scale(GSES). Results: In the terms of general self-efficacy, the score of male students was significantly higher than that of female students, the score of freshman was significantly higher than that of other grades(t/F=7.32, 5.56, P<0.01). In terms of physical activity, the middle and high level physical activity of girls was significantly higher than that of boys, but the proportion of boys meeting the recommended amount was higher(P<0.01). Low level physical activity was the highest in junior college students(31.75%), medium level physical activity was the highest in freshmen (46.75%) and sophomore student (48.13%), and high level physical activity was the highest senior college students (30.40%). The moderate level of physical activity was the highest in all BMI groups, while the lean group had the lowest level of low level physical activity (15.70%) and the highest level of high level physical activity(37.31%), and the lowest proportion meeting the recommended amount(P<0.05). Self-efficacy had a positive predictive effect on physical activity(OR=1.04, 95%CI=1.03-1.05). Conclusion During the COVID-19 epidemic, there are significant differences in general self-efficacy and physical activity among college students by gender, grade and BMI. The general self-efficacy has a positive impact on physical activity, suggesting that college physical education should pay attention to students- self-efficacy, while considering individual and group differences, and promote physical activity level through self-efficacy improvement.

Objective To clarify the relationship between endocrine treatment compliance and medication beliefs of estrogen receptor-positive (ER +) breast cancer patients. Methods Totally 219 patients who were diagnosed as breast cancer and received endocrine therapy in a tertiary hospital were investigated using general condition questionnaire, Morisky Medication Adherence Scale, Beliefs about Medicine Questionnaire(BMQ)by means of face to face,telephone,WeChat.Data analysis was conducted by SPSS 19.0. Results The score of universal beliefs for ER+breast cancer patients was(13.38±5.35) points.The score of the necessary perception was(9.98±4.69)points.The score of the adverse effects of medication was (5.35 ± 2.67) points. The drug compliance score was (5.82 ± 2.15) points.The correlation coefficient of the medication beliefs and the endocrine treatment compliance was 0.578.The Pearson correlation coefficient of each dimension and the total questionnaire was 0.411 to 0.456. Conclusions For ER+breast cancer patients, the higher the medication beliefs is, the better the endocrine treatment compliance is.So it is provided an insight that nurses should enhance the ER +breast cancer patients′medication beliefs in order to get a better and longer survival life.

Objective To systematically evaluate the risk of primary lung cancer in breast cancer patients. Methods A computer-based search was conducted for the English literatures about the risk of primary lung cancer in breast cancer patients in Medline, Scopus and Embase databases. Two researchers independently screened the literatures, extracted the data and assessed the risk of bias. The statistical analysis was performed using the Stata 15.5 software. Results A total of 7 references were included, and the overall risk of primary lung cancer in female breast cancer patients was slightly higher than that in the general population (SIR: 1.18, 95%CI: 1.09-1.27). Subgroup analysis showed that the risk of lung cancer was significantly increased in women aged < 50 years after diagnosis of breast cancer (SIR: 1.99, 95%CI: 1.48-2.69). Conclusion Compared with the general population, the risk of primary lung cancer is increased in female breast cancer patients, especially in young women with breast cancer.

Objective To explore the prognostic factors of the pathological complete response of internal mammary lymph node (ipCR) after neoadjuvant chemotherapy and its effect on breast cancer prognosis. Methods We retrospectively analyzed the clinical data of 70 patients with primary breast cancer with internal mammary lymph node metastasis who received neoadjuvant chemotherapy. Patients were divided into the ipCR group and non-ipCR group based on their postoperative pathology. χ² test, Fisher, and Logistic regression were used for univariate and multivariate analysis. Meanwhile, the Kaplan-Meier curve and Cox regression were used for prognostic analysis. Results Of 70 patients, 31 obtained ipCR (44.3%). Univariate analysis showed that the expression levels of apCR, HR, and HER2 status were related to ipCR (P < 0.05). Multivariate analysis showed that age, apCR, and HER2 status were independent predictors of ipCR (P < 0.05). The average DFS of ipCR group was better than non-ipCR group (96.0 vs. 67.1 months, P < 0.05). The risk of recurrence and metastasis was 87% lower in the ipCR group than in the non-ipCR group (HR=0.13, 95%CI: 0.04-0.44, P < 0.01). ipCR, Ki67 expression level, and breast pCR (bpCR) were independent factors affecting patients' prognosis. Conclusion There is a correlation between clinico pathological factors and ipCR after neoadjuvant chemotherapy. ipCR can be used to predict the prognosis of patients with internal mammary lymph node metastasis.
