Objective:To study the the mechanism of action of Huanglong Mixture in the treatment of cough variant asthma (CVA) in children based on the IL-4/signal transduction and activator of transcription 6 (STAT6) signaling pathway using network pharmacology methods, molecular docking techniques, and in vitro cell experiments.Methods:The components and targets of various TCM components in Huanglong Mixture were searched in TCMSP database, HERB database and literature, and the disease targets of CVA were found in Gene Cards database, OMIM database, DrugBank database and PharmGkb database. The STRING database was used to construct the protein-protein interaction network, and Cytoscape 3.9.1 was used for topology analysis to screen out the core targets. The disease-drug-component-target network was constructed to screen out the core components. The KEGG enrichment analysis and GO enrichment analysis of the intersection targets were performed using Metascape software. PDB protein database, PubChem, Autodock and R language were used for molecular docking verification of core targets and core drug components. Finally, rat primary airway smooth muscle cells were cultured, modeled with interleukin-4 (IL-4), and p-STAT6 expression in the cytoplasm and nucleus was detected by Western blot.Results:A total of 122 effective components were obtained, including quercetin, kaempferol, luteolin and so on. The core targets included JUN, ESR1, TP53, MYC, HIF1, etc. GO enrichment analysis involved biological processes such as response to external stimuli, response to oxygen levels, positive regulation of protein phosphorylation, and regulation of cellular stress response. KEGG enrichment analysis showed that the main pathways of Huanglong Mixture in treating CVA included advanced glycation end product-glycation end product receptor (AGE-RAGE) signaling pathway, phosphatidylinositol-3-kinase-protein kinase B (PI3K-Akt) signaling pathway, tumor necrosis factor (TNF) signaling pathway, Janus kinase/signal transduction activation factor (JAK-STAT) signaling pathway. Molecular docking found that the core targets and core drug components had good combination. Cell experiments also confirmed that Huanglong Mixture could inhibit p-STAT6 entering the nucleus.Conclusions:The effective components and targets of Huanglong Mixture in the treatment of CVA are successfully predicted. The mechanism of Huanglong Mixture in the treatment of children with CVA may be related to the inhibition of IL-4/STAT6 signaling pathway.

OBJECTIVE To provide the suggestions for improving t he enthusiasm of the public to report adverse drug reactions （ADRs），promoting pharmaceutical manufacturers to improve the smoothness of ADR reporting channels by the public and the enthusiasm of assuming the main responsibility for drug safety ，and to provide reference for the performance of drug safety supervision by regulatory departments in China. METHODS Taking 180 pharmaceutical manufacturers that had entered the top 1 000 in the world as the objects ，the questionnaire was prepared to investigate the smoothness of ADR reporting channels through 4 channels：contact number ，e-mail，official website and new media （including Wechat and microblog ） of enterprise . The questionnaire involved the establishment of public reporting channels ，the records and the feedback of enterprises. The existing problems were analyzed and suggestions were put forward. RESULTS & CONCLUSIONS More than 70％ of pharmaceutical manufacturers in China had established the channels for reporting ADR by the public ，which were mainly regular channels such as contact numbers and e-mail ，and each channel had the phenomenon that ADR information couldn ’t be reported. More than 60％ of the public channels established by manufactures lacked inquiry and supplement for the miss ing part of th e reported information ； only 24 pharmaceutical manufacturers provided feedback on ADR information ，and the feedback contents were monotonous. gywf2021-11It is suggested that pharmaceutical manufacturers should pay more attention to ADR monitoring among the public ，consider increasing multiple reporting channels while ensuring the smoothness of channels ，strengthen the training of employee ’s information collection ability to improve the quality of information ，timely feed back the ADR information reported by the public ， and increase the feedback content concerned by the public.

OBJECTIVE To provide re ference for accurate measurem ent of population health status ，pharmacoeconomic evaluation and guidance of health resource allocation. METHODS Using quota and convenient sampling ，five administrative villages were selected from the rural areas under the jurisdiction of Liuzhi special zone ，Qianxi city and Jianhe county of Guizhou province from July to September 2020. Based on the gender and age ratio quota of rural population in the results of the national census，330 respondents were selected for questionnaire survey. The contents of the questionnaire included the self-made scale containing sociodemographic characteristics and general health information ，five-level EuroQoL five-dimension questionnaire （EQ-5D-5L，hereinafter referred to as the “new dimension scale ”）with cognitive dimensions （including attention ，memory， computing ability and learning ability ）and mini-mental state examination （MMSE）. The effects of reliability ，validity and new dimensions of new dimension scale on respond ents’quality of life were investigate ，and its measurement characteristics were verified；the application value of it in pharmacoeconomic hy_cheer@126.com evaluation and guiding the allocation of health resources were explored. RESULTS A total of 330 questionnaires weredistributed，320 were recovered and 320 were effective. The recovery rate and effective rate were 96.97％ and 100％ respectively. The ceiling effect of new dimension scale was 13.44％，the split-half reliability was 0.821，and the overall Cronbach ’s α was 0.852. Exploratory factor analysis showed that the new dimension scale was loaded with physiological ，cognitive and psychological factors ，and the cumulative contribution rate was 69.35％. The correlation coefficient between the new dimension and the dimension of MMSE scale were 0.19-0.61，showing a moderate or medium to strong correlation （P＜0.01）. Compared with EQ- 5D-5L，after adding each dimension ，the interpretation ability of the regression model was improved by 5.00％-17.50％. CONCLUSIONS The new dimension scale has high feasibility ，good reliability and validity ，significantly reduces the ceiling effect of EQ- 5D-5L，has higher sensitivity to the evaluation of people ’s quality of life，and can better evaluate the quality of life of rural population. It is suggested that it can be applied for quality of life evaluation，intervention effect analysis and related economic evaluation.

Objective:To investigate whether the real-world marital status is a factor affecting the survival of patients with early stage breast cancer.Methods:According to the data of 62 845 patients with early stage (T 1-2N 0M 0) breast cancer who received treatment from January 2012 to December 2015 in the Surveillance, Epidemiology and End Results (SEER) database, univariate survival analysis for 7 factors including age, race, surgery, T stage, tumor differentiation, molecular type and marital status was performed by Kaplan-Meier method. The 5-year cancer specific survival (5-CSS) rate was calculated. Multivariate Cox proportional hazards model was used to analyze the death risk of patients with different marital status (married, unmarried and bad marriage). Results:Univariate analysis showed that 7 factors were correlated with the survival of patients with early stage breast cancer (all P < 0.001). Multivariate analysis showed that marital status was an independent factor affecting the survival of patients, and the death risk of unmarried patients and patients with bad marriage was 2.014 times (95% CI 1.714-2.367, P < 0.001) and 2.559 times (95% CI 2.254-2.905, P < 0.001) higher than that of married patients, respectively. In tumor differentiation, molecular type, T stage and race subgroups, univariate analysis showed that the rates of 5-CSS in married patients were higher than those in unmarried patients and patients with bad marriage (all P < 0.001); multivariate analysis showed that the risk of death in patients with bad marriage (except undifferentiated type) was higher than that in married patients (all P < 0.001), and the risk of death in unmarried patients (except undifferentiation, Luminal B type, black and other races) was also higher than that in married patients (all P < 0.01). Conclusions:Marital status is one of the factors influencing the survival of patients with early stage breast cancer.

Objective:To compare the dosimetric difference between intensity-modulated photon radiaotherapy (IMRT) planning and intensity-modulated proton radiotherapy (IMPT) planning for glioma.Methods:The clinical data of 15 glioma patients who underwent IMRT in ion medical center of the First Affiliated Hospital of USTC from November 2020 to April 2022 were retrospectively analyzed. IMRT planning and IMPT planning were designed for the image of each patient in the therapy planning system. Main dosimetric parameters were compared including plan target volume (PTV), coverage index (CI), dose homogeneity index (HI), and maximal dose (D max) and mean dose (D mean) of organs at risk between both plans. Results:There were no significant differences between IMRT planning and IMPT planning in terms of D max and D mean of PTV1 and PTV2, CI and HI (all P > 0.05). Compared with IMRT planning, brainstem D mean [6.92 GyE (0.09 GyE, 12.58 GyE) vs. 24.41 GyE (2.59 GyE, 34.18 GyE)], left optic nerve D max [0.78 GyE (0.04 GyE, 25.18 GyE) vs. 20.42 GyE (6.38 GyE, 37.17 GyE)], left optic nerve D mean [0.10 GyE (0.01 GyE, 11.63 GyE) vs. 9.74 GyE (2.99 GyE, 20.87 GyE)], right optic nerve D mean [1.57 GyE (0.13 GyE, 14.90 GyE) vs. 14.08 GyE (2.66 GyE, 23.67 GyE)], left len D max [0 GyE (0 GyE, 2.91 GyE) vs. 4.84 GyE (1.42 GyE, 5.48 GyE)], left len D mean [0 GyE (0 GyE, 1.73 GyE) vs. 3.84 GyE (1.25 GyE, 4.30 GyE)], right len D max [0.25 GyE (0.04 GyE, 4.55 GyE) vs. 4.28 GyE (1.58 GyE, 5.84 GyE)], right len D mean [0.16 GyE (0.01 GyE, 1.95 GyE) vs. 3.73 GyE (1.04 GyE, 4.86 GyE)], pituitary D max [6.97 GyE (0.18 GyE, 39.70 GyE) vs. 36.60 GyE (2.74 GyE, 45.19 GyE)], pituitary D mean [1.36 GyE (0.06 GyE, 13.85 GyE) vs. 24.74 GyE (2.42 GyE, 32.80 GyE)], hippocampus D max [5.10 GyE (0.24 GyE, 26.52 GyE) vs. 35.83 GyE (5.03 GyE, 46.11 GyE)], hippocampus D mean [0.36 GyE (0.04 GyE, 25.65 GyE) vs. 18.79 GyE (2.37 GyE, 28.10 GyE)] in IMPT planning were lower, and the differences were statistically significant (all P < 0.05). There were no statistical differences in brainstem D max [51.98 GyE (0.66 GyE, 53.43 GyE) vs. 53.29 GyE (3.87 GyE, 53.48 GyE)], right optic nerve D max [9.60 GyE (0.01 GyE, 43.32 GyE) vs. 25.37 GyE (3.45 GyE, 41.25 GyE)] of both plans (all P > 0.05). Conclusion:In the radiotherapy for glioma, IMRT and IMPT can meet the dose demand in clinic. Furthermore, IMPT planning can protect organs at risk and reduce radiation dose in hippocampus, brainstem, optic nerve, lens and pituitary.

Objective:To compare and analyze the complications of end-to-side ileocolon anastomosis and trans-side-to-side anastomosis in laparoscopic assisted radical resection of right colon cancer.Methods:A total of 104 patients with right colon cancer who were treated in the same medical group from March 2018 to October 2019 in Department of General Surgery, the Affiliated Cancer Hospital of Zhengzhou University were selected as the research subjects. All patients were randomly divided into observation group and control group, each with 52 cases. The end-to-side ileocolon anastomosis was used in the observation group and trans-side ileocolon anastomosis in the control group. The operation time, anastomotic fistula, intestinal obstruction and anastomotic stenosis cases, the first time of postoperative exhaustion, and the time of defecation, etc. were counted in two groups of patients, and the occurrence of postoperative complications related to two different anastomosis methods were compared and analyzed. The software of SPSS22.0 was used to conduct statistical analysis, the counting data was expressed by n(%) and the measurement data was expressed as mean ± standard deviation. The comparison of the two groups was by independent sample t test, the comparison of count data was by χ2 test. Results:After the operation of the two groups of patients, there was no significant difference in operation time, first exhaust time, first defecation time and intraoperative blood loss between the observation group and the control group ( P>0.05). The total incidence of complications such as anastomotic fistula, anastomotic stenosis, anastomotic bleeding, and intestinal obstruction in the observation group after surgery was 3.84% (2/52), and the total incidence of complications in the control group was 15.38% (8/52). The two groups had statistical significance in total postoperative complications ( χ2=3.983, P=0.046). Conclusion:In laparoscopic-assisted radical colonectomy for right colon cancer, the choice of anastomosis based on ileocolonic anastomosis can reduce the incidence of postoperative complications and enable patients to obtain better treatment results, thus it can be given priority consideration.

OBJECTIVE:To improve the education quality of medical school,so as to provide the excellent human resources for the field of health.METHODS:2011-2014 grades of students majoring in pharmaceutical administration,pharmacy (marketing direction) and other non-medical interdisciplinary subjects were selected from our school to complete the questionnaire which conrained the questions about satisfaction and confidence for the major.The results of investigation were analyzed statistically.RESULTS:Totally 2 668 questionnaires were sent out,and 2 435 were recycled with effective recovery of 91.27％.Half of the students majoring in pharmaceutical administration or pharmacy (marketing) etc.were switched from other majors,and 38.40％(935 number) of the students wanted to change the major.The major of clinical,nursing and anesthesiology were most preferred by the students.Only 15.52％ (378 number),26.32％ (641 number) of the students thought that the school paid enough attention to them or had a positive attitude to their major,respectively.Students majoring in pharmacy (marketing) and health services administration had the lowest satisfaction about their major and the attention paid by the school (P＜0.001).With the growth of grade,the satisfaction of students in various aspects had declined (P＜0.001).Only 44.72％ (1 089 number),34.25％ (834 number) of the students had positive attitude towards the study or were optimistic about the future,respectively.With the growth of the grade,students' satisfaction in all aspects had declined (P＜0.001).Compared to other students,freshman had more positive attitude towards the study or were more optimistic about the future (P＜0.001).Besides,33.65％ (491 number)of the students planning to work immediately after graduation lacked confidence to find a good job.CONCLUSIONS:The lower degree of satisfaction and confidence are found in the students majoring in non-medical interdisciplinary subject in the medical school,and this should be treated seriously by the school.

and indexes of the ROI which had significant difference between the groups. Results In the white matter regions, MD, D∥and D⊥in many regions of AD group were increased significantly than the control group, and the differences were statistically significant. MD and D ⊥ showed more abnormalities, including the SCC, PCB, and FWM. Meanwhile, MK, K∥and K⊥in many regions of AD were decreased, and the differences were statistically significant. K ⊥ showed more abnormalities, including the SCC, FWM and TWM. In the gray matter regions, MD, D∥and D⊥of hippocampal of the AD group were all increased than the control group. However, it showed that MK and K⊥of the thalamus in AD group were 0.99 ± 0.10, 1.00 ± 0.11, respectively, and both increased than the control group (the value of MK and K⊥were 0.90±0.06, 0.90±0.07, respectively), and the differences were statistically significant (t values was 3.31, 3.57 respectively, and both P values were<0.01). The indexes of different ROI had correlations with the MMSE scores. There were more regions in kurtosis indexes correlated with the MMSE scores than the diffusion indexes. The strongest correlation among the analyses was MK of the SCC (r=0.73, P<0.05). Conclusions This study based on DKI found the complex alterations aroused by microstructural changes were not only in the white matter but also the gray matter of the AD patients, especially the increased kurtosis of the thalamus, and this suggested that the microstructural complexity of it was increased. Moreover, it also suggested that indexes of DKI had varied sensitivity in detecting different diffusion alterations.
