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.

BACKGROUND: Paraquat (PQ) is an effective herbicide and is widely used in agricultural production, but PQ poisoning is frequently seen in humans with the lung as the target organ. Clinically pulmonary pathological changes are often used to predict the severity and prognosis of the patients. In this study, we observed the expression of heat shock protein 70 (HSP70) in rat lung after PQ poisoning and to investigate the therapeutic effects of ulinastatin. METHODS: Seventy-two adult healthy SD rats were randomly divided into a control group (group A, n=24), a poisoning group (group B, n=24), and an ulinastatin group (group C, n=24). The rat models of acute PQ poisoning were established by intra-gastric administration of 80 mg/kg PQ to rats of groups B and C, and the rats of group C were intra-peritoneally injected with 100000 IU/kg ulinastatin 30 minutes after poisoning. The expression of HSP70 in lung tissue was observed, and W/D and histopathological changes in the lung tissue were compared 12, 24, 48 and 72 hours after poisoning. The expression of HSP70 in the lung tissue was assayed by using RT-PCR. All quantitative data were processed with one-way analysis of variance to compare multiple sample means. RESULTS: Compared to group A, the expression of HSP70 in the lung of rats in groups B and C increased significantly at all intervals (P<0.05). The pathological changes in lung tissue of rats with PQ poisoning included congestion, leukocytes infiltration and local hemorrhage, whereas those of group C were significantly lessened. CONCLUSION: Ulinastatin may ameliorate acute lung injury to some extent after PQ poisoning in rats by enhancing the expression of HSP70.

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.

?ig-h_3 was first identified as a transforming growth factor-beta1-inducible gene in human lung adenocarcinoma cell line. It encodes for a secreted extracellular matrix (ECM) protein, which is thought to act on cell attachment and ECM composition. Previous study showed that ?ig-h_3 were highly expressed in human hepatoma cell lines and lowly expressed in human normal hepatic cells. The present study aimed to transfect ?ig-h_3 into 7721 cells to investigate its effect on secretion of MMPs in the transfected human hepatoma cells. Full-length ?ig-h_3 gene,cloned by reverse transcription polymerase chain reaction (RT-PCR) was inserted into the eukaryotic expression vector pEGFP-C_2. The recombinant plasmid was transfected into 7721 cells with Lipofectamine2000 and Gelatin-Zymography were adopted to detect the production of MMPs in the transfected cells. Results showed that ?ig-h_3/pEGFP-C_2 recombinant expression plasmid was successfully constructed and achieved high transfection efficiency. MMPs expression of the transfected cells was promoted significantly. These results suggest that overexpression of ?ig-h_3 promoted the production of MMPs, indicating that ?ig-h_3 may play roles in the invasive and metastatic processes of hepatoma.
