Objective To study the genetics pattern of bronchial hyperresponsiveness and serum total IgE in asthma pedigree. Methods Twenty-eight asthma families were collected, including 124 individuals, 72 with asthma and 52 without. Forty-five normal subjects of three generations without consanguinity among one another, 22 male and 23 female, were chosen as controls, excluding those with family history of asthma and hypersensitivity. Serum total IgE by ELISA and bronchial hyperresponsiveness (BHR) were detected in asthma pedigree members. Genetics pattern of BHR and serum total IgE was analysed. Results The frequency distribution of BHR was bimodal. Individuals with higher level of total IgE occupied 40 of BHR-affected. Conclusion BHR may be controlled by a single major gene. BHR and total IgE may be under separate genetic control.

BACKGROUND:For patients with degenerative mitral annulus dilatation complicated by atrial fibrilation, atrial fibrilation is needed to be treated concomitant with artificial valve ring implantation. Although Cox maze III procedure is the gold standard for treatment of atrial fibrilation, its safety has been questioned. OBJECTIVE:To evaluate the safety of artificial valve rings implantation and Cox Maze III procedure for treatment of degenerative mitral annulus dilatation complicated by atrial fibrilation. METHODS: A total of 43 patients with degenerative mitral annulus dilatation and atrial fibrilation were enroled and were randomly divided into test group (n=21) and control group (n=22). Patients in the test group were treated with mitral valvuloplasty and Cox Maze III procedure. Patients in the control group were only treated with mitral valvuloplasty. RESULTS AND CONCLUSION: (1) Intraoperative safety indexes: the durations of cardiopulmonary bypass and aortic clamping. and the incidence of hemoglobinuria in the test group were higher than those in the control group (P < 0.001). There was no significant difference in the urine output between these two groups. (2) Postoperative safety indexes: the incidence of atrial dysrhythmia (i.e., any atrial dysrhythmia other than atrial fibrilation), proportion of patients requiring a temporary pacemaker and hospital stays in the test group were higher than those in the control group (P < 0.05). There were no significant differences in the secondary-thoracotomy bleeding rate and incidence of stroke between these two groups. (3) Postoperative outcomes: the rates of cardioversion to achieve sinus rhythm at the day of surgery and at discharge in the test group were significantly higher than those in the control group (P < 0.001). At discharge, patients in both groups were al at NYHA functional class Ior II. Echocardiography showed trace to mild mitral regurgitation and complete closure of the tricuspid valve. There were no significant differences in the left atrial diameter, left ventricular diameter, left ventricular volume, and ejection fraction between these two groups. However, the proportions of mitral and tricuspid valve peak A-waves were significantly higher than those in the control group (P < 0.001). These results show that artificial valve ring implantation and Cox Maze III procedure is a safe and effective method for treating degenerative mitral annulus dilatation complicated by atrial fibrilation during operation.

Objective Through experiments in vitro,we explored the role of Chinese medicine monomer-Astragaloside Ⅳ with DC vaccine in the body immunologic function.Methods Peripheral blood mononuclear cells (PBMCs)from healthy volunteers were isolated,cultured and generated in vitro,pulsed with tumor antigen from SGC7901 gastric carcinoma cell lysates,produced DC vaccine.Observe T-cell proliferation responses stimulated by DC vaccine with AⅣ group,DC vaccine group and AⅣ group respectively,and the anti-tumor effects on SGC7901 cells in vitro.Results ①The T-cell proliferation rate of DC vaccine with AⅣ group and DC vaccine group were significantly higher than AⅣ group and T-cell group(negative control group)(P=0.000).The stimulating efficacy on T-cell proliferation of DC vaccine with AⅣ group was higher than that of DC vaccine group(S/R 1∶5,1∶10,1∶50,1∶100,P=0.013,0.014,0.017,0.019).Compared with T-cell group,the T-cell proliferation rate of AⅣ group had no statistically significance(P=0.185).②The killing rate of effector cells actived by DC vaccine with AⅣ group and DC vaccine group against SGC7901 gastric carcinoma cells were higher than that of AⅣ group and T-cell group(P=0.000).The Killing power of DC vaccine with AⅣ group was stronger than that of DC vaccine(E/T 5∶1,10∶1,20∶1,50∶1,P=0.023,0.012,0.016,0.011);while the group of AⅣ group and T-cell group cannot killing tumor cells.Both had no statistically significance(P=0.267).Conclusion AⅣ can stimulate T-cell proliferation and enhance the activity of killing tumor cells by DC,which induced specific antitumor response against stomach carcinoma cells effectively.

OBJECTIVE To investigate the basic situation of developing pharmacy outpatient departments in Chinese tertiary medical institutions and analyze the influencing factors. METHODS The research targeted the pharmacy outpatient department managers of hospitals and conducted a survey through Sojump in March 2023. Various independent variables were selected from the hospital’s own characteristics， the management of the pharmacy outpatient departments， and the construction of the pharmacist team for Logistic and linear regression analysis， with the aim of separately analyzing the factors influencing the establishment of pharmacy outpatient departments and the factors affecting the total number of patients served by these departments throughout the year 2022. RESULTS & CONCLUSIONS A total of 1 304 medical institutions of different levels nationwide participated in this survey， with 714 tertiary hospitals. Among the tertiary hospitals， 377 （52.80%） had established pharmacy outpatient departments， including 321 grade-A tertiary hospitals， 48 grade-B tertiary hospitals and 8 other tertiary hospitals. The 377 tertiary hospitals collectively operated 1 739 pharmacy outpatient departments， covering 19 specialized fields， with the highest proportion found in the cardiovascular field （including anticoagulation） at 16.45%. Tertiary hospitals in North China， Central China， East China and South China regions had more pharmacy outpatient departments. The establishment of pharmacy outpatient departments was found to be influenced by tertiary grade-B status （P＝0.010） and the annual outpatient volume of the hospital （P＝0.008）， although the impact was relatively small. The factors influencing the number of patients served by pharmacy outpatient departments were the annual outpatient volume of the hospital （P＝0.042） and the number of pharmacists engaged in clinical pharmacy work （P＝0.004）. The proportion of tertiary hospitals in China that have established pharmacy outpatient departments is insufficient. It is necessary to further accelerate the construction of pharmacy outpatient departments and appropriately expand the talent pool of hospital pharmacy teams based on the needs of pharmacy outpatient departments and patients， in order to meet the requirements of medical practice and patient care.
