Objective To investigate the medication rules for the treatment of hepatopathy by national medical masters. Methods The prescriptions for hepatopathy were collected to build a database based on Traditional Chinese Medicine (TCM) inheritance assist system. After analyzed by the data mining, such as apriori algorithm and complex system entropy cluster, the frequency of single medicine and drug combinations that used in prescriptions, and the association rules among drugs were obtained. Results The most frequently used drugs were Herba Artemisiae Capillaris, Tuckahoe, Radix Salviae Miltiorrhizae, Rhizoma Atractylodis Macrocephalae, and Radix Bupleuri, et al. The most frequently used drug combinations were “Radix Salviae Miltiorrhizae, Tuckahoe”, “Rhizoma Atractylodis Macrocephalae, Tuckahoe”, and “Radix Salviae Miltiorrhizae, Herba Artemisiae Capillaris”, et al. And when the confidence of drug association rules was 1, the drug combinations were“Radix et Rhizoma Rhei, Giant Knotweed→Herba Artemisiae Capillaris”,“Radix et Rhizoma Rhei, Radix curcumae→Herba Artemisiae Capillaris”, “Giant Knotweed, Gardenia→Herba Artemisiae Capillaris” and so on. Conclusion The medicines were often with the actions of clearing heat, removing dampness, regulating qi and activating blood circulation, which were used for the treatment of hepatopathy by national medical masters.

Objective To explore the clinical phenotype of airways disease in elderly patients using hierarchical cluster analysis.Methods A total of 67 elderly patients with respiratory symptoms were enrolled in a prospective study.Demographic and clinical data,such as respiratory symptoms,cumulative tobacco cigarette consumption,acute exacerbation,atopic symptoms and peak flow diary were collected.Pulmonary function tests,blood tests (total serum IgE level and blood eosinophil level) were performed in each patient during the stable stage.Then patients with different clinical phenotype were identified by hierarchical cluster analysis.Results Four clusters were identified with the following characteristics by hierarchical cluster analysis:cluster 1,atopic patients with no smoking,normal lung function,but increased total serum IgE levels and asthma symptom;cluster 2,patients with no smoking and normal pulmonary function with wheezing but without chronic cough;cluster 3,patients with chronic obstructive pulmonary disease and smoking,severe airflow limitation and poor quality of life;cluster 4,patients with asthma-chronic obstructive pulmonary disease overlap syndrome and smoking,airflow limitation and increased total serum IgE levels.The forced expiratory volume in 1 second (FEV1) / forced vital capacity (FVC) ratio,FEV1/predicted value,rate of FEV1 change,maximal mid-expiratory flow (MMEF)/ predicted value,the diffusion lung capacity for carbon monoxide (DLCO)/alveolar volume (VA)/predicted value,residual volume (RV)/ predicted value,total serum Ig E levels,cumulative tobacco cigarette consumption,the St.George's Respiratory Questionnaire (SGRQ) score had significant differences in patients before versus after treatment (all P＜0.05 or P＜0.01).Conclusions Based on hierarchical cluster analysis,distinct clinical phenotypes of airways disease in elderly patients can be identified.Conclusions With patients having asthma or COPD alone,patients with Asthma-COPD overlap syndrome (ACOS) always experience a more rapid decline in lung function and frequent exacerbations,having poor health-related quality-of-life (HRQOL) outcomes,which deserve our high attention.

Objective To study the effects of Weibimei and its Chinese medicine portions(cortex frangulae, fennel powder, acorus tatarinowii, glycyrrhizae and asparagus) on cell cycle regulation in gastric cancer cells and growth inhibition in gastric cancer Xenografts.Methods Gastric cancer SGC-7901 cells were normally cultured and treated with Weibimei, extractum glycyrrhizae, cortex frangulae, fennel powder, acorus tatarinowii and asparagus.Then, the proliferation of SGC-7901 cells were detected by MTT assay, their effect on SGC-7901 cell cycle were measured by flow cytometry, and the expression of cell cycle related proteins were examined by Western blot.Animal models of SGC-7901 cells xenografts in nude mice were constructed to evaluate the growth inhibition effects of Weibimei and its Chinese medicine portions, and the expression of STAT3,p-STAT3, Cyclin D1, Bcl-2 and Survivin in gastric tumors were detected by immunohistochemical assays.Results Weibimei and its three kinds of Chinese medicine portions, cortex frangulae, fennel and acorus tatarinowii could obviously inhibit the proliferation of SGC-7901 cells, compared to control group, with a statistical significant difference (P<0.05).The cell cycle of SGC-7901 was arrested at G1 phase with cortex frangulae, fennel and acorus tatarinowii treatment, the expression of Cyclin A, B, D, E were decreased significantly (P<0.05).However, no significant effects was found in glycyrrhizae or asparagus group.Xenografts tumor sizes in Weibimei, cortex frangulae, fennel or acorus tatarinowi groups were much smaller than that in saline group or Triple Therapy group (three-kinds-drugs-combination for the treatment of gastric ulcer) (P<0.05).Xenografts experiments showed that the tumor growth in nude mice in Weibimei, cortex frangulae, fennel or acorus tatarinowi groups were significantly smaller than that in control group or in Triple Therapy Group (P<0.05), and phosphorylated STAT3, and STAT3 signaling targeted genes, including Bcl-2, Cyclin D1 and Survivin were all significantly down-regulated by immunostaining.Conclusion Weibimei and its Chinese medicine portions including cortex frangulae, fennel and acorus tatarinowii can could significantly inhibit the growth of SGC-7901 cells proliferation and arrested the cell cycle of G1 phase in vitro, and inhibit gastric cancer xenografts in nude mice in vivo.

Objective:To investigate the efficacy and adverse reactions of simultaneous integrated boost intensity-modulated radiotherapy (SIB-IMRT) combined with chemotherapy in the treatment of superior mediastinal lymph node metastasis after esophageal cancer surgery.Methods:The clinical data of 72 patients with concurrent chemoradiotherapy for superior mediastinal lymph node metastasis after esophageal cancer surgery in Tai'an Cancer Prevention and Treatment Hospital from January 2019 to May 2021 were retrospectively analyzed, and they were divided into intensity-modulated radiotherapy (IMRT) group (36 cases) and SIB-IMRT group (36 cases) according to different radiotherapy methods. The short-term efficacy, long-term survival rate and adverse reactions of the two groups were compared.Results:The response rate in the IMRT group was 66.7% (24/36), the response rate in the SIB-IMRT group was 86.1% (31/36), and the difference between the two groups was statistically significant ( χ2 = 3.77, P = 0.047). The 1-, 2- and 3-year overall survival rates in the IMRT group were 75.0%, 44.4% and 27.8%, and the 1-, 2- and 3-year overall survival rates in the SIB-IMRT group were 83.3%, 52.8% and 33.3%; the difference in the overall survival between the two groups was not statistically significant ( χ2 = 0.70, P = 0.401). There were statistical differences in the incidence of leukopenia, radiation esophagitis and radiation pleural gastritis between the two groups (all P < 0.05). There were no statistical differences in the incidence of radiation pneumonia and gastrointestinal reactions between the two groups (both P > 0.05). Conclusions:SIB-IMRT combined with chemotherapy in patients with superior mediastinal lymph node metastasis after esophageal cancer surgery has good local control rate and mild adverse reactions.
