Objective]To research the regulation of L-type calcium channels by Xuanfu Daizhe soup in the lower esophageal sphincter(LES) smooth muscle of rabbit reflux esophagitis model induced by mixed perfusion of hydrochloric acid and bile. [Methods]Established the rabbit model of mixed reflux esophagitis, nifedipine was used to block L-type calcium channel.The muscle tension of L-type calcium channel were compared among groups in the experiments. [Results]The calcium releasing and flowing phase of LES in the model group was higher than that in the normal group, the whole recipe group, sweet-scending group, the getting rid of bitter-reducing group and the getting rid of lifting and declining group( P<0.01). There was no significant difference between the model group and bitter-reducing group, the lifting and declining group and the getting rid of sweet-ascending group( P>0.05). There was no significant difference between the normal group and the whole recipe group in calcium releasing and flowing phase of LES( P>0.05). [Conclusion]The decreasing of reflux esophagitis model LES tension was relevant with the L-type calcium channel dysfunction;Xuanfu Daizhe soup could improve the LES tension by regulating L-type calcium channels. The sweet-ascending group had a remarkable effect among those dismantle prescription groups.

Tumor suppressor CYLD is a deubiquitination enzyme that could regulate NF-?B and JNK signal pathways by deubiquitinating TRAFs,NEMO,Bcl-3 and p53,and in turn regulating the cell cycle and apoptosis.Loss or deficiency of CYLD would lead to the development of skin tumor,including multiple familial trichoepithelioma(MFT),familial cylindromatosis(FC),Brooke-Spiegler syndrome(BSS).Cancers like uterine cervix,kidney,and colon and hepatocellular carcinoma are related to the down-regulation of CYLD.

Objective To study the effect of the serum levels of 25-hydroxyvitamin D3 [25-(OH)D3] and total IgE (TIgE) in pathogenesis of the children bronchial asthma.Methods Twenty-two children with bronchial asthma (bronchial asthma group) and 20 healthy children (control group) were selected.The serum levels of 25-(OH)D3 and TIgE in the children of 2 groups were detected.Results The level of serum 25-(OH)D3 in bronchial asthma group was significantly lower than that in control group [(23.64 ± 3.89)μ g/L vs.(35.82 ± 4.37) μ g/L],there was statistical difference (P ＜ 0.05).The level of serum TIgE in bronchial asthma group was significantly higher than that in control group [(208.62 ± 32.59) kU/L vs.(73.84 ± 18.86) kU/L],there was statistical difference (P ＜ 0.05).There was negative correlation between the level of serum 25-(OH)D3 and TIgE in bronchial asthma group (r =-0.832,P ＜ 0.01),but there was no correlation between the level of serum 25-(OH)D3 and TIgE in control group (r =-0.038,P ＞0.05).Conclusions The lack of 25-(OH)D3 may be associated with allergy and childhood bronchial asthma.By monitor the levels of 25-(OH)D3 and TIgE may assess condition of childhood bronchial asthma.

BACKGROUND: It is confirmed that panel reactive antibody (PRA) and its immune level is closely related to rejection activation, renal survival rate and the realization of the renal function. Study addressing the relation PRA level and acute rejection has great clinical significance for forecasting acute rejection and improving the renal survival rate.OBJECTIVE: To analyze the relation of PRA and acute rejection prior to and after transplantation by detecting PRA level combined with patient rejection.DESIGN, TIME AND SETTING: Retrospectively case analysis was performed at the Affiliated Beijing Friendship Hospital of Capital University of Medical Sciences from September 1998 to May 2005.PARTICIPANTS: A total of 633 patients receiving renal transplantation were collected, including 348 males and 285 females, aged 16-67 years.METHODS: Company Lymphocyte Tray produced by One Lambda and Biotest were used for this study, serum PRA level was detected prior to and within 2 months after transplantation.MAIN OUTCOME MEASURES: Pre- and post-transplant PRA level and clinical rejection.RESULTS: Totally 591 patients were PRA negative in pre-transplant assay, and 164 patients were positive, 10.32% (61/591) patients occurred acute rejection; 42 patients were PRA positive in pre-transplant assay, and 71.42% (30/42) patients occurred acute rejection. The difference between PRA negative or positive and acute rejection had significance (P < 0.001). 427 patients were PRA negative in both pre- and post- transplant assay, 5.6% (24/427) patients occurred acute rejection. 164 patients were PRA negative in pre-transplant assay, but positive in post-transplant, 42.7% (70/164) patients occurred acute rejection. The comparison of PRA negative pre-transplant and PRA positive post-transplant combined with acute rejection had difference (P < 0.001). The correlation coefficient of pre-transplant PRA and acute rejection was 0.612, which was 0.658 between post-transplant PRA and acute rejection, there was obvious association when P=0.01.CONCLUSION: PRA plays an important role in forecasting renal rejection. The acute rejection probability is higher in patients with positive PRA; in other hand, the probability is lower in patients with negative PRA.

Objective To study the correlation between transplanted kidney dysfunction and oc-currence of the panel reactive antibody ( PRA, also referred as anti-HLA antibody ) and anti-Major-Histo-compatibility-Complex class Ⅰrelated chain A (MICA) antibody.Methods The tests for detecting PRA and anti-MICA antibody were performed on 679 renal transplant patients from December , 2009 to June, 2010 who received transplantation before 2008 in Beijing Friendship Hospital .Enzyme-Linked Immunosor-bent Assay ( ELISA) was used to detect anti-HLA antibody using LAT-1240 ( OneLambda Inc .) .MICA Ab-Scan Kit was adopted to detect anti-MICA antibody .Continuous observation of graft function was conducted . Results 108 out of 679 patients showed anti-HLA antibody and/or anti-MICA antibody positive results . Among them, 81 patients were positive only for anti-HLA antibody, 18 patients were positive only for anti-MICA antibody and other 9 patients showed anti-HLA and anti-MICA antibodies double positive .Among all of the kidney transplant patients with a failed or decreased renal function , 71 patients were positive for anti-HLA antibody;16 patients were positive for anti-MICA antibody;and other 9 patients were positive for both anti-HLA and anti-MICA antibodies .The results demonstrated that anti-HLA and anti-MICA antibodies af-fected the renal functions in patient with renal transplantation (χ2 =353.92, P <0.001).Conclusion Anti-HLA and MICA antibodies showed significant positive correlations with chronic allograft failure in the patients with renal transplantation .

Objective:To explore the application effect of small private online course (SPOC) teaching mode in clinical practice teaching of thoracic surgery.Methods:A total of 56 undergraduate students who were internships from May to July 2018 were selected as subjects. They were randomly divided into experimental group and control group. SPOC teaching mode and traditional teaching mode were respectively adopted in the practice teaching, and the teaching effect was evaluated by questionnaires and written examinations. SPSS 22.0 was used for statistical analysis, ttest for independent-sample test, and chi-square test for counting data. There were significant differences when P<0.05. Results:The questionnaire showed that the six teaching effect evaluation indicators of the experimental group were higher than those of the control group ( P<0.01). In terms of written test assessment, the average score of the experimental group was significantly higher than that of the control group, with significant differences ( P<0.05). Conclusion:The SPOC teaching mode can improve the teaching effect of clinical practice in thoracic surgery and improve students' self-learning ability.

OBJECTIVETo compare the difference in clinical efficacy on bronchial asthma at chronic persistent stage between acupuncture for warming yang and benefiting qi and seretide.

METHODSOne hundred and eighty patients of bronchial asthma at chronic persistent stage were randomized into an acupuncture group and a western medication group, 90 cases in each one. In the acupuncture group, acupuncture for warming yang and benefiting qi was applied at Dazhui (GV 14), Feishu (BL 13), Danzhong (CV 17), Dingchuan (EX-B 1), Jianshi (PC 5), Zhigou (TE 6), Taixi (KI 3) and Zusanli (ST 36), once every two days. In the western medication group, inhalation therapy with seretide was applied, 1 to 2 inhalations each time, twice a day. The treatment for 20 days was as one session in the two groups, at the intervals of 2 days after each session. Four sessions of treatment were required. The immune function indices were observed before and after treatment in the patients of two groups, named immunoglobulin IgG, IgM and IgE; peripheral T lymphocytes (CD3+), helper T lymphocytes (CD4+), inhibitory T lymphocytes (CD8+) and the ratio of CD4+ and CD8+; as well as the pulmonary ventilation function indices, named maximum pulmonary expiratory flow (PEF), forced expiratory volume in one second (FEV1) and forced vital capacity (FVC). The clinical efficacy was compared between the two groups.

RESULTSThe total effective rate was 93.3% (84/90) in the acupuncture group, better than 88.9% (80/90) in the western medication group (P < 0.05). After treatment, the immune function indices and pulmonary ventilation function indices were apparently improved as compared with those before treatment in the two groups (all P < 0.05). The improvements in the acupuncture group were much more significant (all P < 0.05).

CONCLUSIONAcupuncture for warming yang and benefiting qi effectively controls the symptoms of bronchial asthma at chronic persistent stage and improves immune and pulmonary functions. The efficacy is better than that of seretide.

Objective To analyze the sensitized factors in urinemia patients who waiting for renal transplantation.Methods 2429 patients with urinemia from April 2002 to December 2008 were subjected to the detection of panel reactive antibody, and classified into 5 groups according to their clinical data:(A) no history disease group (n = 1097) who never experienced transfusion, pregnancy and transplantation; (B) Transfusion group (n = 361) who received transfusion more than 200 ml; (C) Pregnancy group (n = 481) who experienced pregnancy; (D) Transfusion+ pregnancy group (n= 294) who experienced both pregnancy and transfusion; (E) Re-transplantation group (n = 196) who experienced failed transplantation before, and waited for the second renal transplantation.Results All the males in group A were negative for PRA, and females were weakly positive for HLA Ⅱ antibody.The incidence of PRA production in group B was 15.24 % (55/361).Thirty-nine patients were positive for PRA in group C with the incidence being 8.11 % (39/481).The PRA positive rate in groups D and E was 30.61 % (90/294) and 70.92 % (139/196) respectively.PRA intensity was more than 60 % in 72 patients in group E.Conclusion Transfusion and pregnancy caused lower incidence of PRA positive rate.The incidence was much higher in transfusion + pregnancy patients than that in patients with transfusion or pregnancy alone.Graft caused the higher incidence of PRA than by transfusion and pregnancy.

Objective To investigate the HLA antibody incidence and type renal recipients with different age, and to study the echaracteristics in different age patients, for clinical reference to forecast renal rejection in different age patients. Methods With serum dated from January 2006 to June 2008, patients were classified into three groups: young group, with age below 35 years; middle age group, with age from 36 to 50 years; and old group, with age above 50 years. Penel reactive antibody (PRA) were detected using ELISA. Results Pretransplant HLA antibody incidences in the young, middle age, old group were 18.18%, 23.00% and 6.19%, respectively. In young group, HLA antibody incidences were 5.59% and 8.51% in male and female respectively. In middle age group, they were 21.30% and 25.38% in male and female respectively. In old group, they were 11.36% and 25.00% respectively. HLA Ⅰ and HLA Ⅰ + Ⅱ antibodies were mainly found in all the three groups in pretansplant. Conclusion HLA Ⅰ and HLA Ⅰ + Ⅱ antibodies were mainly found in pretransplant. Antibody incidence was higher in patients who had more than once renal transplant than that in transfusion and pregnancy female. Antibody incidence is higher in female than that in male.

Aim To figure out whether Lonicera mac-ranthoides could induce hemolysis. Methods In vitro, macroscopic observation and spectrophotometry were used to observe whether the solutions of extracts from Lonicera macranthoides, MacranthoidinB and Dipsa-cosideB could induce hemolysis in 2% red cell suspen-sion of New Zealand white rabbits. And the three test-ed materials were prepared in concentration gradient of 5, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 mg· L - 1; and in vivo, mice were respectively treated with MacranthoidinB (0. 110 g·kg - 1 , 0. 055 g·kg - 1 ), DipsacosideB(0. 020 g·kg - 1 , 0. 010 g·kg - 1 ), ex-tracts (2. 275 g·kg - 1 , 1. 137 g·kg - 1 , crude drugs) once per day for 7 days, and all of the tested doses de-pended on the clinical doses. Then, RBC, RET and MCHC before and after administration were tested. Re-sults The hemolytic ratio in each treated group was below 5% in vitro. And in vivo, the three materials did not induce hemolysis and had no significant influence on RBC,RET and MCHC(P > 0. 05). Conclusions Extracts from flower bud of Lonicera macranthoides, MacranthoidinB and DipsacosideB, have not caused hemolysis in vivo and in vitro in this research.
