Efficacy of desloratadine citrate disodium in the treatment of chronic urticaria and its effect on serum interleukin-23, interleukin-33 and PARC/CCL-18 / 中华皮肤科杂志

Objective To compare the efficacy of desloratadine citrate disodium versus loratadine in the treatment of chronic urticaria (CU),and to evaluate their effect on serum interleukin (IL)-23,IL-33 and pulmonary and activation-regulated chemokine/CC chemokine ligand 18 (PARC/CCL-18).Methods From January 2013 to December 2016,120 CU patients treated in Department of Dermatology,Wuwei Oncology Hospital were enrolled into this study,and divided into study group and control group by using a random number table.Patients in the study group took oral desloratadine citrate disodium tablets 8.8 mg once a day,and patients in the control group took loratadine tablets 10 mg once a day.The treatment lasted 28 days.The therapeutic effect was compared between the two groups,and changes in serum levels of IL-23,IL-33 and PARC/CCL-18 were compared before and after treatment.Statistical analysis was carried out by using two-sample t test and chi-square test for comparing indices between the two groups.Results The response rate was significantly higher in the study group (88.33％,53/60) than in the control group (61.67％ [37/60],x2 =15.352,P ＜ 0.01).After the treatment,the serum levels of IL-23,IL-33 and PARC/CCL-18 in the study group significantly decreased to 87.72 ± 22.16 ng/L,95.94 ± 18.27 ng/L,85.93 ±27.34 μg/L respectively,which were all lower than those in the control group (104.21 ± 32.05 ng/L,106.27 ±20.93 ng/L,95.72 ± 30.28 μg/L,respectively;t =3.264,4.034,3.934,respectively,P =0.020,0.006,0.015,respectively).No significant difference was observed in the incidence of adverse reactions between the study group and control group (P =0.298).Conclusion Desloratadine citrate disodium can markedly improve the clinical symptoms of CU with favorable safety,likely by inhibiting the immune response of the body and reducing the effect of chemokines on the chemotaxis of inflammatory cells.

Effects of uncoupling protein 3 gene -55 C-->T variant on lipid metabolism, body fat, its distribution and non-insulin-dependent diabetes mellitus in Chinese / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To investigate the relationship of UCP3 gene -55 C-->T variant with lipid metabolism, body fat, its distribution and non-insulin-dependent diabetes mellitus(NIDDM) in Chinese.</p><p><b>METHODS</b>Polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP) was used to detect the genotype of UCP3 gene -55 C-->T in a total of 316 Chinese including 165 individuals with normal glucose tolerance(NGT) and 151 patients with type 2 diabetes). MRI was used to detect local body fat; the enzyme method and sulfate-sephadex-manganese precipitation method were used to detect TC and HDL-C, and then LDL-C was calculated with corresponding formula.</p><p><b>RESULTS</b>(1)No difference was seen on comparing allele and genotype frequencies of Chinese with those of Caucasian (P=0.1120 and P=0.0646, respectively), whereas significant difference in these frequencies was seen between Chinese and Pima Indians(P=0.0 105 and P=0.0314, respectively). (2)Stepwise regression analysis revealed that the independent variables to UCP3 gene -55 C-->T were: HDL-C(P= 0.013)and LDL-C(P=0.012) in male NGT subgroup FA(P=0.023) in female NGT subgroup TG(P=0.004)in male DM subgroup, and waist to hip ratio (WHR)(P=0)in female DM subg roup. (3)The allele frequency of DM group was significantly different from that of NGT(P =0.0358). The odd ratio for the T allele carrier with NIDDM was 1.434 (95%CI 1.031-1.995).</p><p><b>CONCLUSION</b>Although UCP3 gene 55 C-->T variant is associated with lipid metabolism, body fat and its distribution in Chinese, the association is dependent on sex and disease status. The variant is also associated with NIDDM in Chinese.</p>

Application of the immunofluorescent technique for diagnosing muscular dystrophy / 中华神经科杂志

Objective To establish a specific detection technique in patients with Duchenne muscular dystrophy (DMD),Becker muscular dystrophy (BMD) and limb-girdle muscular dystrophy (LGMD). Methods Immunofluorescent technique was applied,and 4 monoclonal antibodies against dystrophin,?-sarcoglycan (?-SG) and ?-sarcoglycan (?-SG) were respectively used.Results Dystrophin was negative in 9 DMD patients,and partially absent in 4 BMD patients. In two LGMD patients,50DAG was diminished in one patient and 35DAG was diminished in the other. Therefore,the two patients were diagnosed as having LGMD2D and LGMD2C respectively. Conclusion Analysing gene product expressed on surface membrane of muscle fiber is helpful to diagnose and classify the DMD/BMD,and LGMD diseases by using immunofluorescent technique.

Relationship between ApoE gene polymorphism and type 2 diabetes mellitus with its nephropathy in Chinese / 中国糖尿病杂志

0.05).Conclusion In Chinese,ApoE allele ?2 may be a risk factor for developing diabetic nephropathy complication.No correlation between ApoE gene polymorphism and type 2 diabetes mellitus was found in Chinese.
