We retrospectively analyzed 218 allergen skin prick tests ( SPT ) of the patients with chronic sinusitis with or without nasal polyps( CRSwNP/CRSsNP) before the operation. The proportions of positive SPT in CRSwNP and CRSsNP were compared respectively. The distributions of allergens were the same in all groups. The positive rate of SPT in CRSwNP was higher than that in CRSsNP, with statistical significance(P<0. 05). The positive rate of SPT in CRSsNP was higher than that of the control group, without statistical significance. The recurrence rate in CRSwNP was higher than that in CRSsNP, with statistical significance. The recurrence rate in the allergen-positive patients was higher than the allergen-negative patients, with statistical significance.

Objective To investigate the curative effect and adverse reaction of caffeic acid (CFA) for leukopenia and thrombocytopenia caused by imatinib in chronic myeloid leukemia (CML) patients.Methods The effect and adverse reactions of CFA for leukopenia or thrombocytopenia induced by imatinib in 42 CML patients were observed.The CFA was admitted by 0.2 g/time,3 times/d,oral.Results 21 cases of 42 CML patients with thrombocytopenia achieved remarkable curative effect after CFA treatment,13 achieved good effect and 8 had no effect.The total effective rate was 81.0 ％ (34/42).While 15 of 28 leukopenia CML patients achieved remarkable curative effect,8 achieved good effect and 5 had no effect.The total effective rate was 82.1％ (23/28).After CFA therapy for 2 weeks,both platelet and white blood cells count were elevated compared with before treatment,the differences were statistically significant (t =2.015,P =0.023,t =1.913,P =0.035).The average onset time of CFA for leukopenia and thrombocytopenia was 2 weeks and no treatment-related adverse reaction was found.Conclusion CFA is an effective and safe auxiliary drug for treatment of imatinib-induce leukopenia and thrombocytopenia in patients with CML.

Objective To assessment the effect of autologous mastoid cortical bone to cover the mastoidetomy defect via transmastoid and posterior tympanotomy approach surgical technique during cochlear implantation in a ‐dults .Methods A total of 58 adults patients with profound sensorineural hearing loss accepted cochlear implantation from January 2010 and June 2014 ,which were using autologous mastoid cortical bone to cover the mastoidetomy de‐fect via transmastoid and posterior tympanotomy approach surgical technique .By observing postoperation complica‐tion the effect of surgery was evaluated .ABR were obtained for each patients at first ,third and sixth month after op‐eration .The patients which were not using autologous mastoid cortical bone to cover the mastoidetomy defect via transmastoid and posterior tympanotomy proach surgical technique acted as control group .Results No depression was found in the postauricuhtr site .None of the patients had experienced any immediate or delayed postoperative in ‐fection complication such as wound infection ,post - auricular abscess ,acute otitis media ,chronic otitis media ,in‐tracranial complication and necrotic of cortical bone .Autologous cortical bone cap had grew together with remnant cortical bone in all cochlear implantation patients .All implanted processor were in a good position ,all patients had good results after turning on the implant .The ABR thresholds were elevated about 70 dB compare to pre - operation values(P< 0 .05) .There was no significant difference compare to control group (P> 0 .05) .Conclusion The tech‐nique of autologous mastoid cortical bone to cover the mastoidetomy defect in cochlear implantation surgery can pre ‐vent depression of the postauricuhtr site ,remain stability of the implanted processor ,and have a good aided hearing thresholds after operation .

Objective To investigate the effect of AP-2α on the chemoresistance to oxaliplatin of colorectal carcinoma cell and its related mechanism.Methods Plasmid of GV102-AP-2α-RNAi (experimental group) and control plasmid GV102-NC (negative control group) were transfected into HCT-116 using Lipofectamine 2000 respectively.The AP-2α expression levels of mRNA and protein of experimental group,control group and HCT-116 blank group were detected by qRT-PCR and Western blot.Cell proliferation assay was performed using the CCK-8 and the apoptosis assays were preformed with Annexin V-PE Apoptosis Kit.Results The AP-2α expression levels of mRNA and protein both decreased after transfection of AP-2α-RNAi plasmid,moreover,the effect produced by subsequence 1 was the most significant.After treatment by oxaliplatin,AP-2α protein levels increased with time while mRNA did not change significantly.Western blot results suggested that the level of AP-2α protein in experimental group which was maintained in oxaliplatin was lower than the negative control group.CCK-8 results suggested that cell proliferation ability was significantly higher for the experimental group maintained in oxaliplatin [(88±3) ％] than the negative control group maintained in oxaliplatin [(57±3) ％] and the blank group maintained in oxaliplatin [(73t4) ％].Flow cytometry showed that the apoptosis rate of the experimental group maintained in oxaliplatin [(15.07±1.20) ％] was lower than the control group maintained in oxaliplatin [(24.93±0.90) ％] and the blank group maintained in oxaliplatin [(23.71±1.32) ％].Conclusion AP-2α may be related to the sensitivity of colon cancer cells to oxaliplatin.

ObjectiveTo investigate the association of HLA-Cw and -DRB1 alleles with psoriasis vulgaris,and to provide a clue to the study into the etiology of psoriasis.MethodsVenous blood samples were obtained from 81 patients with psoriasis vulgaris collected during 2006-2011 at the Department of Dermatology,First Affiliated Hospital of Inner Mongolia Medical College,as well as 100 age- and gender-matched healthy controls.Both the patients and controls are unrelated Mongolia in Inner Mongolia.PCR with sequence-specific primers(PCR-SSP) technique was used to genotype the HLA-Cw and DRB1 loci.ResultsThe patients with psoriasis vulgaris showed a significantly higher frequency of HLA-Cw*06(0.438 vs.0.175,Pc ＜ 0.01) and DRB1*07(0.241 vs.0.110,Pc ＜ 0.012),but a lower frequency of HLA-Cw*04(0.031 vs.0.150,Pc ＜ 0.01 ) and DRB1*04 (0.093 vs.0.235,Pc ＜ 0.01 ) than the healthy controls did.Increased frequencies of HLA-Cw*06 and DRB1*07 alleles were observed in patients with an onset before 40 years of age and those without a family history,together with a decreased frequency of HLA-Cw*04 and DRB1*04 alleles,compared with the healthy controls(Pc ＜ 0.05).The frequency of HLA-Cw*06 allele was significantly higher in patients with a positive family history and patients with an onset of no younger than 40 years of age than in the healthy controls (both Pc ＜ 0.05).ConclusionsHLA-Cw*06 and -DRB1*07 alleles may be susceptibility determinants to psoriasis vulgaris,while HLA-Cw*04 and -DRB1*04 alleles may be protective factors against psoriasis vulgaris,in Mongolia from Inner Mongolia.HLA-DRB1*07 allele may be a susceptibility gene for psoriasis,while HLA-Cw*04 and -DRB1*04 alleles may be protective factors against psoriasis,in patients with an onset before 40 years of age.

Objective: To investigate all trans retinoid Acid (ATRA) inhibition of cell growth in human retinoblastoma Y79 cells, and its mechanism. Methods: Antiproliferation effects of ATRA on Y79 cells were determined by 3 H thymidine incorporation. Cell cycle analysis was performed by flow cytometry. JNK phosphorylation was analyzed by Western blot analysis. Results: After 36 h treatment with 10 -6 mol?L -1 ATRA, 3 H thymidine incorporation decreased to 40%, under the same condition, Y79 cells were arrested in G 0 /G 1 and Sub G 1 peak appeared. Curcumin, JNK blocker, blocked the growth inhibition by ATRA. JNK was phosphorylated in 10 to 20 min. Conclusion: JNK phosphorylating mediated ATRA inhibition of apoptosis in Y79 cells. These results suggested that ATRA might have clinical application for treatment of retinoblastoma.

Objective To follow up the rehabilitation, education, and assistive devices utilization of school age children with cerebral palsy. Methods From 2012 to 2015, 80 children with cerebral palsy were called their parents with telephone and filled in the questionnaires. Results 69 children (85.25%) continued to receive rehabilitation, 11 children (13.75%) stopped rehabilitation. 42 children (56.25%) received education in ordinary schools, 15 children (18.75%) received education in special schools, 4 children (5.00%) were nursed in nursing institu-tion, 16 children (20.00%) stayed at home and did not receive any education. The main problem and needing at present were receiving reha-bilitation, receiving school education, relief the rehabilitation cost of more than one institution, etc. 61 children (76.25%) ever applied for as-sistive devices, 19 children (23.75%) did not. The feedback of application process in order were smoothly;applied, but didn't get;the assis-tive devices that received was inappropriate. 29 children (73.75%) needed assistive devices currently, 21 children (26.25%) did not. When asked the category of needed assistive devices at present, 19 parents (20%) answered that they did not know the category of assistive devices well or they did not know which kind of assistive devices they needed. Conclusion It is important to provide quality and quantity rehabilita-tion and education service, popularize the knowledge of assistive devices and their clinical application for cerebral palsy children. Assistive devices providing departments should do more communication with cerebral palsy children and their parents, in order to reduce the waste of resources, and increase the rational use of resources, and provide more benefits for children with disabilities.

Objective To investigate the association between Bsml polymorphism in vitamin D receptor (VDR) gene and diabetic nephropathy in Chinese Han population. Methods PCR-restriction fragment length polymorphism (PCR-RFLP) was used to test the genotype and allele frequency of Bsml in 304 patients with type 2 diabetes mellitus (DM group) and 100 healthy individuals (NC group).The DM group was further divided into non-diabetic nephropathy group (DN0 group,122 cases),minimal albuminuria group (DN1 group,87 cases),and mass albuminuria group (DN2 group,95 cases).Eighty-three DM patients without nephropathy for over 5 years were L-NDN subgroup,and 64 DM patients with nephropathy occurring within the first year were EDN subgroup. Results Genotype and allele frequency of BsmI polymorphism were significantly different between DM and NC group (x2=7.088,P=0.008;x2=5.865,P=0.015).BB+Bb genotype and B allele frequency were significantly higher in DN2 group than those in NC group (x2=14.287,P=0.000;x2=12.621,P=0.000) and DN0 group (x2=8.063,P=0.005;x2=8.173,P=0.004).BB+Bb genotype and B allele frequency were significantly higher in EDN group than those in L-NDN group (x2=7.228,P=0.007; x2=5.853,P=0.016).DN patients with allele B (BB and Bb genotypes)presented higher urinary albumin excretion rates compared with patients without allele B (bb genotype,P＜0.01).The genotype of BsmI was correlated with DN,and allele B was risk factor of DN occurrence and early onset (OR=2.004; OR=2.394). Conclusion VDR gene BsmI polymorphism is associated with DN,and the patients carrying allele B are more involved in mass albuminuria and eady onset of nephropathy.

Objective To evaluate the effectiveness and safety of percutaneous transhepatic balloon dilation for the removal of common bile duct stones.Methods 60 patients of common bile duct stone were divided into two groups:PTBD group (30 cases) and endoscopic sphicterotomy (EST) group (30 cases).Postoperatively biliary tract was drained for three days.Results All stones were removed in 28 patients (93％) in PTBD group and 29 cases (97％) in EST group.Early complications occurred in 13％ in PTBD patients and in 17％ in EST patients(x2 =0.35,x2 =0.13,P ＞0.05).There was no mortality in neither group.Long-term complications such as gallstone recurrence and cholangitis in PTBD group was significantly less than that in EST group (x2 =6.41,P ＜ 0.05).Conclusions The success rate of PTBD was similar to that of EST and while in PTBD the function of Oddi's sphincter was well reserved.PTBD procedure is a valuable alternative to EST in patients with bile duct stones,especially in patients who are not suitable for EST.
