Objective To analyze and discuss the medication rule of professor Ruan Yan in the treatment of children with allergic rhinitis by using data mining method,and to provide reference for the clinical research and patented drugs development for the treatment of children with allergic rhinitis.Methods The outpatient medical records of professor Ruan Yan for the treatment of children with allergic rhinitis were collected.Microsoft Excel 2010 software was used for frequency statistics.SPSS Clementine 12.0 software was used for association rule analysis,cluster analysis and factor analysis to obtain the data.The frequency of use of various drugs and the association rules between drugs were obtained.Then the medication rules in professor Ruan Yan's prescription were analyzed.Results A total of 308 Chinese medicine compounds were included,involving 80 kinds of Chinese medicines,among which relieving drugs and qi-invigorating herbs were high-frequently used.The distribution of traditional Chinese medicine syndrome types was mainly characterized by lung-qi deficiency-cold syndrome and lung-spleen qi deficiency syndrome.The medicinal properties were mainly spicy,warm and sweet,and most of them belonged to the lung,spleen and stomach meridians.Five core prescriptions were extracted by factor analysis.Four drug combinations were obtained by systematic cluster analysis.Conclusion Ventilating lung and opening the orifices,expelling wind and removing cold,strengthening the spleen and replenishing qi are basic therapeutic principles for professor Ruan Yan in the treatment of children with allergic rhinitis.The treatment mainly focused on dispelling evil,ventilating lung and opening the orifices,expelling wind and removing cold during the acute stage of allergic rhinitis.In the remission period,according to the principle of"treating disease must be based on its origin",the treatment should enhance children's physical fitness,tonify lung and strengthen spleen,thereby reducing recurrence.

ObjectiveTo investigate the therapeutic effect of Xiao Qinglongtang （XQLT） on ovalbumin （OVA）-induced allergic rhinitis （AR） in mice and its effect on the interleukin-33 （IL-33）/suppression of tumorigenicity 2 （ST2） signaling pathway. MethodSeventy-two female BALB/c mice of SPF grade were randomly divided into a control group， a model group， a positive control group （loratadine， 2.05 mg·kg^-1）， and low-， medium-， and high-dose （5.005，10.01，20.02 g·kg^-1） XQLT groups. All mice except for those in the control group were sensitized by intraperitoneal injection of OVA solution， and the AR model was induced by intranasal drops of OVA solution. Thirty minutes before local intranasal drops， drugs were administered once， and mice in the control group and the model group received phosphate buffered saline （PBS） at 20 mL·kg^-1 for 7 days. After the last intranasal drop of OVA solution， the times of sneezing and nasal rubbing of mice within 10 min was recorded. After drug administration for 7 days， blood samples were collected， and nasal bones of mice were decalcified for the preparation of pathological sections. The content of OVA-specific immunoglobulin E （OVA-sIgE）， interleukin-4 （IL-4）， interleukin-5 （IL-5）， and interleukin-13 （IL-13） was detected by enzyme-linked immunosorbent assay （ELISA） kits. Hematoxylin-eosin （HE） staining， periodic acid-Schiff （PAS） staining， and Giemsa staining were used to observe the pathological changes， goblet cell hyperplasia， and eosinophil infiltration of nasal mucosa， respectively. Western blot was used to detect the expression levels of IL-33， ST2， and IL-1 receptor accessory protein （IL-1RAP） in nasal mucosa. ResultCompared with the control group， the model group showed increased times of sneezing and nasal rubbing （P<0.01）， edema and thickening of nasal mucosa， goblet cell hyperplasia and eosinophil infiltration， increased serum levels of OVA-sIgE， IL-4， IL-5 and IL-13 （P<0.01）， and increased protein expression of IL-33， ST2， and IL-1RAP in nasal mucosa （P<0.05，P<0.01）. After drug administration， compared with the model group， the high-dose XQLT group showed reduced times of sneezing and nasal rubbing （P<0.01）， improved pathological conditions of nasal mucosa， reduced serum levels of OVA-sIgE， IL-4， IL-5， and IL-13 （P<0.01）， and declining protein expression of IL-33， ST2， and IL-1RAP in nasal mucosa （P<0.05，P<0.01）. ConclusionXQLT has a therapeutic effect on OVA-sensitized AR mice， and the mechanism may be related to the regulation of the IL-33/ST2 signaling pathway and Th2 inflammatory cytokine to reduce Th2 inflammatory response and alleviate nasal mucosal injury.

Objective To investigate the antagonism of third generation dihydropyridine calcium channel antagonist beni-dipine in contraction induced by potassium chloride(KCl)in human internal mammary artery(IMA),and in order to explore the possibility of using benidipine as an antispastic agent during coronary artery bypass grafting(CABG). Methods The IMAs were taken from 19 patients undergoing CABG. The vasodilator effect(n = 7)on KCl-induced contraction and the inhibition effect(n = 6)after incubation with benidipine were studied in a myograph. The caveolin 1. 2 was detected(n = 3,2 cases re-spectively)by enzyme-linked immunosorbent assay (ELISA). Results The maximum relaxation caused benidipine was (87. 7 ± 4. 9)％ . Incubation with benidipine significantly depressed the contraction by KCl[from( 16. 9 ± 4. 4)mN to (9. 1 ± 3. 4 )mN,P < 0. 01]. The concentration of caveolin 1. 2 was down-regulated after incubation with benidipine(P < 0. 05). Conclusion Benidipine has a potent inhibitory effect on KCl-induced vasoconstriction. The relaxation may be related with the expression of caveolin 1. 2. Using benidipine in patients undergoing CABG may provide antispastic effects in grafts.

Background:Inflammatory bowel disease (IBD)is a group of chronic gastrointestinal inflammatory disease and its diagnosis depends on analysis of clinical,endoscopic and pathological characteristics. Aims:To analyze the clinical, endoscopic and pathological characteristics of IBD. Methods:Clinical,endoscopic and pathological characteristics of 99 patients with IBD [including 61 ulcerative colitis (UC)and 38 Crohn's disease (CD)]from January 2010 to April 2017 at Yijishan Hospital were retrospectively analyzed. Results:Compared with CD patients,age in UC patients was significantly increased,incidences of diarrhea,bloody stool were significantly increased while incidence of abdominal mass was significantly decreased (P < 0. 05). Extensive type UC and ileocolonic type CD were common. Proportion of patients received 5-aminosalicylic acid (5-ASA)was significantly higher in UC than in CD (90. 2% vs. 71. 1%,P = 0. 014). Two UC patients achieved remission shown by endoscopy,and endoscopic remission achieved in 3 CD patients. The main pathological features of UC were cryptic branching (57. 1%),cryptic twisting (76. 2%),cryptic atrophy (54. 8%)and cryptic irregularity (28. 6%). Ulcer was seen in 78. 9% of CD patients with active chronic inflammation (mainly lymphocyte and plasmocyte infiltration),and the detection rate of non-caseating granuloma was 15. 8% . Conclusions:UC patients are characterized with older age,diarrhea,bloody stool and higher administration rate of 5-ASA,and the endoscopic features were mucosal bleeding and ulcers. Pathological characteristics of UC were mainly cryptic architectural change and inflammatory infiltration,while those of CD were mainly segmental lesions and chronic inflammation with lymphocyte and plasmocyte infiltration and some with non-caseating granuloma.

Objective: To retrospectively analyze the clinical efficacy and safety of rivaroxaban in the prevention of deep vein thrombosis ( DVT) after bones of lower extremity surgery. Methods:Totally 94 patients with bones of lower extremity surgery were col-lected in our hospital during June 2010 to June 2013. According to the taken medicine, the patients were divided into groupⅠ(rivarox-aban 10 mg,po,qd) and groupⅡ( low molecular weight heparin injection 4 000 IU, ih,qd) . The bleeding after the surgery, the data of blood routine and coagulation, the occurrence of DVT and the adverse reactions in the two groups were compared. Results:After the medicine treatment, the number of hemoglobin and platelet in the two groups was declined significantly (P<0. 05), while reached the normal value after the medicine withdrawal. No significant difference was found in the blood routine and coagulation routine in the two groups. One case of hemorrhea showed in group I, while three cases showed in groupⅡ. GroupⅠhad no DVT, while groupⅡ had 3 cases of DVT, and the difference was significant (P<0. 05). No severe adverse reactions appeared in the two groups. Conclusion:Rivaroxaban has good effect in the prevention of DVT with better efficacy and safety when compared with low molecular weight heparin.

Objective To investigate the changes of B lymphocyte subsets ( naive B cells, memory B cells and plasmablasts) in peripheral blood of patients with rheumatoid arthritis ( RA) and their correla-tions with the clinical manifestation and laboratory indexes.Methods Sixty-six patients with RA were di-vided into two groups including the group with active RA and the group with inactive RA according to the dis-ease activity score in 28 Joints (DAS28).A control group with healthy subjects was set up accordingly.The distributions of B lymphocyte subsets in peripheral blood samples were detected with flow cytometry analysis and their correlations with clinical manifestations and laboratory indicators were analyzed.Results ( 1 ) Compared with healthy subjevts, the mean fluorescence intensities ( MFIs) of CD19 and the percentages of memory B cells in peripheral blood of the patients with RA were significantly decreased, while the percenta-ges of naive B cells were increased (P<0.05).The percentages of plasmablasts in the patients with active RA were significantly increased as compared with those of healthy subjects and the patients with inactive RA (P<0.05).(2) The percentages of plasmablasts in peripheral blood of the patients with RA were positively correlated with the joint tenderness count, joint swelling count and joint swelling index (P<0.05).(3) A positive correlation was found between the MFIs of CD19 and the erythrocyte sedimentation rates ( ESRs ) among the patients with RA.The percentages of plasmablasts were positively correlated with C reaction pro-tein (CRP) and anti-cyclic citrullinated peptide (anti-CCP) antibody (P<0.05).(4) The percentages of plasmablasts were also positively correlated with the DAS28 among the patients with RA ( R2=0.343, P<0.01).Conclusion The distributions of B lymphocyte subsets varied among the patients in different stages of RA, which were related to the patient′s clinical symptoms and laboratory indexes.The study suggested that different subsets of the B lymphocytes might play an important role in the pathological process of RA.

Objective To explore the effect of air pressure wave on the prevention of lower limb deep venous thrombosis in patients with cerebral stroke and the application value of color Doppler ultrasound (CDUS).Methods 72 stroke patients were randomly divided into experimental group (n =37) and control group (n =35) by random digits table.The control group received routine nursing,conventional and rehabilitation therapy.The experimental group was treated by the air pressure wave for 15 days on the basis of the control group.DVT formation of lower extremities and hemodynamic changes before and after treatment was observed by CDUS,and the results were compared with the X-ray phlebography examination results.Results CDUS displayed the incidence rate of DVT in the experimental group was significantly lower than that in the control group (2.7％ vs 20.0％,x2 =5.449,P ＜0.05).The changes of blood flow velocity and the average reflux time of femoral,popliteal vein in the experimental group had significant differences between before and after treatment (t =8.503,4.254,8.587,2.062,all P ＜ 0.05) ;and in the control group,only popliteal vein blood flow velocity had statistically significant difference (t =6.895,2.116,4.169,all P ＜ 0.05).Compared with the X-ray angiography,8 cases of DVT diagnosed by CDUS were consistent,but 1 case of DVT in the control group was missed diagnosis.Conclusion Air pressure wave can effectively reduce the occurrence of DVT in patients with cerebral stroke.CDUS can accurately diagnose the DVT formation,and can help to understand the hemodynamic change,it has important clinical value for monitoring the preventive effect of DVT.

ObjectiveTo investigate the efficacy of rapamycin combined with CsA/Tacrolimus (Tac) in chronic allograft nephropathy (CAN).MethodsFifty-three cases of CAN accepted the quadruple immunosuppressive drug program,which contained rapamycin combined with CsA/Tac and MMF and prednisone,and CsA/Tac and MMF were reduced to the original amount of 25％ to 50％.After treatment for 12 months,more relevant indicators,including serum creatinine,glomerular filtration rate,serum cholesterol,triglycerides,urinary protein,GPT and bilirubin and other changes were observed.ResultsIn the patients receiving quadruple regimen of rapamycin during 12 months,the blood Ccr was decreased from (161.51 ± 106.48)μmol/L before treatment to (126.51 ± 56.2)μmol/L after treatment for 6 months (P＜0.05) and to (123.43 ± 54.18)μmol/L after for 12 months (P＜0.01).The GFR was increased from (0.754 ± 0.302) ml/s before treatment to (0.952 ± 0.347)ml/s after treatment for 6 months (P＜0.05) and to (1.007 ± 0.394) ml/s after treatment for 12 months (P＜0.01).Cholesterol and triglycerides in patients had no significant change before and after treatment.The positive rate of proteinuria after treatment showed an increasing trend from 9.4％ before treatment to 26.4％ after treatment for 12 months.ConclusionThe quadruple program of rapamycin combined with CsA/FK506 and MMF can significantly improve Ccr and GFR in patients with CAN,but it can increase the incidence of proteinuria in patients:

Objective To explore the significance of peritubular capillary C4d deposition in histopathological changes, renal function and prognosis of the patients with antibody-mediated chronic rejection (AMCR). Methods Deposition of C4d in the kidney was examined by irnmunohistochemistry on routine paraffin-embedded sections using anti-C4d polyclonal antibody. Seventy-seven patients were divided into C4d+ group (n = 35) and C4d- group (n = 42). The relationship of C4d and renal function,histopathological changes and prognoses of allografts were analyzed. Results The number of patients with tubular atrophy and glomerular basement membrane proliferation in C4d+ group was significantly more than that in C4d group (P＜0.05). Mean serum creatinine level was significantly higher in C4d+ group than in C4d- group 12 months after renal transplantation [(379.1 + 260.2)μmol/L vs (260.5 + 175.3) μmol/L, P＜0.05]. According to Kaplan-Meier analysis, the one-year graft survival rate was lower in the C4d+ group (62.9% ) than in the C4d- group (83.3% ) (logrank P＜0.05). Conclusion Patients with C4d deposition are associated with tubular atrophy and glomerular basement membrane proliferation. The serum creatinine level in C4d+ patients was significantly higher than in C4d- group at the 12th month after transplantation. More patients with C4d deposition lost their grafts during the study period.
