Objective To translate the English version of Revised Dental Beliefs Survey (R- DBS) into Chinese and to test the reliability and validity of the Chinese version of R- DBS. Methods The R- DBS was translated and adapted according to Chinese culture. The reliability and validity of Chinese version of R- DBS was tested in 348 adult patients in department of stomatology. Results The Chinese version of R- DBS consisted of 23 items. Three factors were extracted by factor analysis which could explain 54.236% of the total variance. The internal consistency coefficient of the Chinese version of R- DBS was 0.891 and the test- retest reliability was 0.856. Using DAS as an external criterion, the correlation coefficients of the DBS and DAS scores were 0.781 (P<0.01). Conclusions The Chinese version of R- DBS is reliable and valid, and can be used to assess the patient′s subjective perceptions of the behavior of dentists and the delivery of dental care.

Objective To investigate effects of laparoscopic repair of abdominal wall incisional hernia using polypropylene and expanded polytetrafluoroethylene(e-PTFE) composite mesh. Methods Forty-one patients with abdominal wall incisional hernia(4~25 cm in length and 3~18 cm in width) were treated in this hospital from October 2004 to August 2005. The patients received laparoscopic mesh herniorrhaphy after complete dissection of adhesion using an ultrasonic scalpel.A polypropylene and(e-PTFE) composite mesh(Bard Composite Mesh) was used and fixed using the Ethicon Endopath Multifeed Stapler(EMS).Results The laparoscopic mesh herniorrhaphy was successfully completed in all the 41 patients without conversions to open surgery.The operative time was 60~182 min(mean,85 min).Postoperatively,the patients felt slight pain and began to take food on the second day.The time to first passing flatus was 25~41 hours(mean,32 hours).The postoperative hospital stay was 5~7 days(mean,6 days).No recurrence occurred during a follow-up period of 6~16 months(mean,9 months) in the 41 patients. Conclusions The laparoscopic incisional hernia repair using the Bard Composite Mesh is a safe and effective method.

Objective To investigate the effects of the polymorphisms in the promoter of ATP binding cassette transporter (ABCG1) on the transcription activity,and the relationship of the polymorphisms with the susceptibility to coronary artery disease (CAD).Methods A case-control study was conducted,217 CADpatients and 142 controls were enrolled in this study.Thesingle nucleotide polymorphisms (SNPs) in the promoter of ABCG1 were identified by sequencing.The promoter haplotypes of ABCG1 were determined with allele specific primer sequencing or Gene cloning sequencing.The transcription activity of the promoter haplotypes were evaluated with dual luciferase reporter system.The frequency of SNPs and haplotypes were analyzed between CAD group and the control group,premature CAD and non-premature CAD group,as well as multivessel lesion and single vessel lesion group.The frequency distribution was compared between two groups with x2 test or Fisher exact test.The difference of the luciferase activity was compared between groups by t-test or one-way analysis of variance.Results Only 3 SNPs were found in ABCG1 promoter sequence of about 1 000 bp upstream of the transcription start site,which are-384 (A/G),-204 (A/C) and-134 (T/G),respectively.The 3 SNPs are in strong linkage disequilibrium,Tajima's D =2.655 (P < 0.01),which constituted 3 haplotypes.There was no significant difference in SNPs and haplotype frequency between the CAD group and the normal control group,and the severity of vascular disease and the early onset of coronary heart disease were not associated with the polymorphisms in ABCG1 promoter.There was no significant difference in the transcriptional activity of the three constitutive promoter haplotypes,but the transcriptional activity was notably elevated as the GAT haplotype was mutated into GAG (P < 0.05).Conclusions The 3 SNPs identified in ABCG1 promoter region A did not alter the promoter activity.There was no significant correlation between the frequency distribution of SNPs and promoter haplotypes and the susceptibility to CAD.

Objective To carry out the clinical validation of a domestic HBsAg kit to evaluate its application value. Methods 543 serum samples with HBsAg ELISA values of S/CO ≥ 0. 7 were tested by HBsAg confirmatory test. Specific anti-HBs reagent and control reagent were added separately into duplicate wells of HBsAg ELISA plate, in which test sample was also added. After incubation at 37℃, HBsAg was detected by routine ELISA, and the inhibition rate was calculated using absorbanee (A) result of anti-HBs reagent well and control reagent well according to the provided formula. The sample was confirmed as HBsAg positive when the inhibition rate was≥50%. For HBsAg weakly positive samples, "prolonged confirmatory test" (conjugate reaction time was prolonged to 120 rain) was applied to increase the sensitivity. 39 samples were randomized selected for testing and comparison with Abbott Murex confirmatory test. Results 543 serum samples in total were tested by the confirmatory test. Among the 504 cases which showed positive reaction in screening HBsAg ELISA, 89 ( 17. 7% ) were confirmed as negative. According to their S/CO value of the screening HBsAg test, the ratio of negative cases / tested eases in the group were:S/CO≤<5.0, 87/143 (60. 8% ) ;5.0 < S/CO ≤ 10. 0,0/25 (0) ;10. 0 < S/CO ≤ 15.0, 1/21 (4. 8% ) ;15.0 < S/CO ≤ 20. 0, 1/23 (4. 4% ) ;S/CO 20. 0, 0/292(0). Among 39 cases with negative HBsAg (0. ≤

AIM: To investigate the role of hydrogen sulfide (H_2S) in the cholecystokinin octapeptide (CCK-8) attenuating lipopolysaccharide (LPS)-induced lung injury. METHODS: A rat model of lung injury induced by intravenous injection of LPS was developed. Male Wistar rats were divided into normal control group, LPS group, LPS+CCK-8 group and CCK-8 group. Six hours after LPS injection, partial pressure of oxygen in the arterial blood (PaO_2), H_2S content and cystathionine-γ-lyase (CSE) activity in lung tissue were detected. The mRNA expression of CSE in lung tissue was determined by RT-PCR;the structure of lung tissues was observed under optical microscope. RESULTS: Compared to normal control rats, the LPS-treated rats had significantly decreased PaO_2 level, increased index of quantitative assessment (IQA) score, while H_2S content, CSE activity and the mRNA expression of CSE in lung tissue were significantly increased (all P<0.05). Administration of CCK-8 into LPS-treated rats increased the PaO_2 level and alleviated the degree of lung injury (measured by IQA score). In addition, CCK-8 decreased H_2S content, CSE activity, and the mRNA expression of CSE (all P<0.05). No significant difference of the above-mentioned parameters between CCK-8 group and normal control group was observed. CONCLUSION: CCK-8 reduces LPS-induced lung injury through inhibiting the generation of endogenous H_2S.

Objective To investigate the variation of interleukin-6 ( IL-6 ) , vascular endothelial growth factor(VEGF),E-selectin and intercellular adhesion molecule-1(ICAM-1)in children with sepsis and the clinical significance. Methods This was a prospective and control study. Thirty-two children diagnosed as sepsis in PICU from December 2008 to December 2009 served as the sepsis group. According to whether there was a shock, sepsis group were divided into shock subgroup and no shock subgroup. Fifteen healthy children served as control group. The serum levels of IL-6,VEGF,E-selectin and ICAM-1 were detected with enzyme linked immunosorbent assay. Results The serum level of IL-6 was 65. 00(30. 49~237. 14) ng/L in shock subgroup and 48. 68(30. 25~75. 00) ng/L in no shock subgroup,which were significantly higher than that in control group[0. 80(0. 60 ~1. 00) ng/L](P<0. 05). There was no significant difference between shock subgroup and no shock subgroup. The serum levels of VEGF and E-selectin showed no significant differences among the three groups. The serum level of ICAM-1 was 998. 72(666. 93~1 526. 44) ng/ml in shock subgroup,and 925. 71(683. 53~1 225. 12) ng/ml in no shok subgroup,which were significantly high-er than that in control group[660. 59(525. 48~685. 47) ng/ml]. Compared with those who survived in sep-sis group,the serum levels of VEGF and E-selectin in the died children with sepsis showed no significant difference,but IL-6 and ICAM-1 significantly increased(P<0. 05). Conclusion IL-6 and ICAM-1 increase greatly and accentuate inflammation in septic patients,the changes of which may help to determine the prog-nosis of sepsis.
