Objective To develop a PCR-SSP method for detection of HLA-DRB1 alleles in the patients who were hypersensitive to Platanus Acerifolia pollen allergen,and to probe into the association between the atopic subjects to Platanus Acerifolia pollen allergen and HLA-DRB1 alleles.Methods DNA in whole blood was extracted by phenol-chloroform method.Eight pairs of specific primers for alleles were synthesized,and HLA-DRB1*0401,*0402,*0403,*0404,*0405,*0406,*0407,*0408 alleles in 20 atopic patients and 36 healthy individuals of Jiangsu Province with Han nationality were detected by PCR-SSP(polymerase chain reaction-sequence specific primer).Results By optimizing the experimental conditions PCR-SSP methods for detection of the 8 alleles were established and the distributing data of above-mentioned HLA DRB1 were obtained.The frequency of HLA DRB1*0405 and *0406 in the patients group was higher than that of in healthy controls group,while the frequency of HLA DRB1*0402 in the patients group was lower than that in controls.No significant deference for the other 5 alleles was found between the 2 groups.Conclusion HLA-DRB1*0406和*0405 seems to be the likely suspected candidate alleles responsible for susceptibility to Platanus Acerifolia pollen allergen in the atopic patients,while DRB1*0402 might be contribute to the related resistance to the allergen.

Objective To develop a reliable scale for evaluating medication compliance among patients with chronic diseases in China.Methods An initial item pool was generated by literature review,based on the definition of compliance generally accepted in China.The items were then subjected to item selections by using item answer distribution and other four methods,which resulted in a primary scale with 16 items.The reliability and validity of this scale was examined.Results Common factors extracted by factor analysis were well explained,there being a close correspondence between the scale construction and the theoretical construction. Convergent validity with the patients' self-ratings on medication compliance ranged from 0.55 to 0.59,and the correlation coefficient with the score of Morisky questionnaire was 0.58.The Cronbach ?,0 and ? coefficients were 0.717,0.751,0.893 respectively,and test-retest reliability was 0.95.Conclusion The newly developed scale appears reliable and may be a useful tool for measuring drug compliance among patients with chronic diseases,but there are still areas where further improvements may be needed.

Objective To investigate the effects of ulinastatin on pulmonary and hepatorenal function of elderly patients undergoing resection of esophageal cancer. Methods The clinical data of 40 elderly patients with esophageal cancer who had been admitted to Southwest Hospital from January 2005 to January 2008 were retrospectively analyzed. All the patients were randomly divided into control group (n = 20) and ulinastatin group (n = 20) according to random number table. Patients were administered with total parenteral nutrition, and patients in ulinaslatin group were additionally instilled with 4×10~5 U/d of ulinastatin. The levels of PaO_2, PaCO_2, PaO_2/FiO_2, alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (Tbil), blood urea nitrogen, creatinine and uric acid were detected preoperatively and at postoperative day 2 and day 6. All the data were analyzed by t-test and chi-square test. Results The levels of PaO_2 and PaO_2/FiO_2 were (87.3±4.2) mm Hg (1 mm Hg =0.133 kPa) and (416±20)mm Hg in ulinastatin group, which were significantly higher than (79.0±4.3)mm Hg and (376±20)mm Hg in control group (t =6.2, 6.2, P <0.05). The levels of ALT, AST and Tbil were (23±7)U/L, (38±8)U/L and (13.4±3.0) μmol/L in ulinastatin group, and (39±8) U/L, (50±9) U/L and (24.5±6.0) μmol/L in control group, with significant difference between the 2 groups (t = 7.0, 4.4, 7.6, P < 0.05). The levels of uric acid, blood urea nitrogen and creatinine were (279±84) μmol/L, (4.1±1.7) mmol/L and (66±12) μmol/L in ulinastatin group, and (386±67)μmol/L, ( 8.9±2.7) mmol/L and (95±38) μmol/L in control group, with significant difference between the 2 groups (t = 4.4, 6.4, 3.3, P < 0.05). The recurrence of complications in ulinastatin group was significantly lower than that in control group (χ~2 = 4.8, P <0.05). Conclusion Postoperative supplementation of ulinastatin and total parenteral nutrition is helpful in improving the pulmonary and hepatorenal function of elderly patients undergoing resection of esophageal cancer.

Patient-reported outcomes (PROs) provide clinical researchers with a good means to assess patient-based outcomes. Yet there are still some problems to pay attention to while using PROs as an effectiveness assessment index, including the selection of an appropriate scale of PRO, quality control in PRO data collection, and the interpretations and application ranges of the PRO results.

0.05); serum HBsAb levels of pregnant mice and neonatal mice in group with CpG-1826 (20 ?g)+hepatitis B vaccine significantly higher than those in group with CpG-1826 (10 ?g, 40 ?g)+ hepatitis B vaccine,hepatitis B vaccine and control respectively(P0.05).Conclusions Combination injection of CpG-1826 20 ?g and hepatitis B vaccine can markedly increase serum antibody levels of pregnant mice and neonatal mice, but don′t affect the survival quantity, the growth and development of neonatal mice.CpG-1826 is an ideal immune adjuvant for neonates with immature immune system during pregnancy.

Objective To explore the feasibility of using irreversible electroporation (IRE)mediating HPV16 E6 shRNA into cervical cancer cell line SiHa,and to clarify the influence of their co-effect on the proliferation of SiHa cells and its mechanism.Methods A HPV16 E6 gene specific interference sequence was inserted in pGenesil-1 to build a interference vector.10 pulses of IRE with 800 V,100 μs,and 1 Hz were applied to the suspension of SiHa cells and vectors.According to the treatment factors,control group,IRE group,pGenesil-N group,pGenesil-N+IRE group,pGenesil-E6 group and pGenesil-E6 + IRE group were set up.The expression of green fluorescent protein (GFP)and transfection efficiency were confirmed by inverted fluorescence microscope 24 h after the vector was transfected by IRE,and the expression efficancy of GFP was calculated.The expression levels of E6 mRNA and protein were detected by RT-PCR and Western blotting method which was also applied to detect the expressions of P53 and PCNA.The proliferative activity of SiHa cells was determined by CCK-8 assay.Results Enzyme digestion and DNA sequencing verified that the vectors were correctly constructed.GFP was seen under inverted fluorescence microscope 24 h after IRE transfection.Compared with IRE group,the expression levels of E6 mRNA and protein were decreased detected by RT-PCR and Western blotting method after the vectors were treated with IRE,the P53 protein expression level was increased (P < 0.05),and the PCNA expression level was decreased (P <0.05).The CCK-8 assay results showed the proliferative activity of SiHa cells in pGenesil-E6+IRE group was decreased more obviously than that in pGenesil E6 group (P <0.05).Conclusion IRE can play the role of gene transfection of mediating HPV16 E6 shRNA into SiHa cells, and their co-effect can significantly inhibit the proliferation of SiHa cells.

Objective This study aimed to evaluate the association between the paraoxonase (PON) genes variants and Alzheimer's disease (AD) using systematic review with meta-analysis.Methods Relevant studies were identified by searching English and Chinese databases extensively.Newcastle-Ottawa Scale (NOS) was employed to evaluate the quality of included studies.The odds ratio (OR) was calculated using a random-effects or fixed-effects model.A Q statistic was used to evaluate homogeneity,and fail-safe number,Egger's test and funnel plot were used to assess publication bias.Results A total of 15 studies were included and identified for the current meta-analysis.The NOS scores ranged from 7 to 8,meaning good quality of studies.It was found that the SS genotype of PON2 S311C polymorphism had an significant association with AD in the studied population (OR=0.82,P=0.04).However,there was no significant relationship between other three genetic variants of PON genes and AD.Conclusions Existing evidence indicated that the PON2 S311C polymorphism (SS genotype) was associated with risk of AD in studied population.Future studies with larger sample sizes will be necessary to confirm the present results.
