Objective To investigate the effects of H. pylori infection on cyclooxygenase 2 (COX 2) expression in gastric antral mucosa. Methods Antral biopsies were taken from 46 patients with chronic gastritis and H. pylori infection before and after anti H. pylori treatment. COX 2 protein was stained by immunohistochemical method. Gastritis and H. pylori infection status were graded according to the updated. Sydney system. Results Cytoplasmic staining of COX 2 protein could be detected in epithelial cell both before and after eradication of H. pylori . The mean percentage of the cells staining with COX 2 was significantly higher in H. pylori infected mucosa, compared with the mucosa after successful H. pylori eradication [(20.1?13.1)% vs (13.8?5.9)%, P

Objective To explore the prevalence of hypertension in children with obstructive sleep apnea syndrome(OSAS).Methods Ninety snoring children were enrolled and stayed in sleeping monitor unit for a night.24 h ambulatory blood pressure(ABP)monitoring and polysomnography were simultaneously carried out. The children were classified depending of [Apnea Hypopnea Index(AHI≥5)] as OSAS group and(AHI

Objective To have insight into the epidemiological situation and to predict the possibilities for achieving the national goal of basic eradication or the WHO target of elimination of leprosy as a public health in the leprosy high－ endemic areas in China. Methods Based upon the data during 1983－ 1996 from the National Leprosy Recording and Reporting Surveillance System and using the appropriate mathematical models, the expected calendar year of reaching the national goal in terms of detection and prevalence rates and the WHO target of elimination under different conditions was predicted. Results Of 337 counties where the national goal of basic eradication of leprosy had not reached and 40 counties where the WHO goal of leprosy elimination had not achieved in 1996, the detection rates in calendar years followed the negatively exponential models with a significant goodness－ of－ fit in 67 and 11 counties, respectively. In the former, the national goal can be met in 6％ of counties before the year 2000 or 34.4％ before 2010 in terms of detection rate, or 31.3％ before the year 2010 in terms of prevalence rate. In the latter, the WHO target can be met in 8－ 10 counties within this century when the duration of disease was determined with the WHO definition. While the MB proportion among new cases increased by 10％ , the target would be met one year later. However, at the same MB proportion, the change of the duration of completing the fixed treatment from PB 0.5 year and MB 2 years to PB 0.75 year and MB 3 years will result in the achievement of the goal 2－ 10 years later. Conclusion The results imply that WHO goal of leprosy elimination can be reached in more than 95％ of counties by the end of this century, but the national goal of achieving basic eradication of leprosy in more than 95％ of counties by this century will not be met, indicating that leprosy control will go beyond the century in China.

Objective To analyze the detection modes of leprosy and their influencing factors and outcomes. Methods Based upon the nationwide registration of leprosy patients detected during 1981～ 1998, the profiles of these patients at detection were studied. Results The proportions of cases significantly correlated with calendar years in the detection by dermatologic clinic, contact check, clue survey and mass survey, showing a significant increases in percentage of cases detected through dermatologic clinic and contact check and decreases through clue survey and mass survey. Detection of leprosy cases through dermatologic clinic and voluntary reporting became the main modes of case－ finding during 1997－ 1998, accounting for 37.3％ and 28.6％ respectively, whereas contact check only accounted for 9.1％ . More MB patients were detected by voluntary reporting than PB, whereas detection by dermatologic clinic resulted in a significantly higher proportion (38.0％ ) in PB patients than in MB (33.5％ ). The voluntary reporting and clue survey resulted in higher proportions of detection in prefecture and county rural areas. In areas with good facilities of dermatologic services, significantly higher extent (75.9％ ) of cases were detected through dermatologic clinic, whereas the voluntary reporting and clue survey were main modes of case detection in endemic areas. A great majority of cases were confirmed by leprosy units even though they were detected by various modes. Only 6.5％ of leprosy cases were detected and consequently confirmed by doctors in dermatologic clinics. Conclusion This study emphasizes the importance of providing training on leprosy to the doctors in dermatologic clinics while continuously encouraging their involvement in leprosy control.

Objective To study clinical characteristics and the trends of leprosy relapse cases after dapsone(DDS) monotherapy or multidrug therapy(MDT) from 1949 to 1998. Methods The data of leprosy relapse cases in China from 1949 to 1998 were analyzed. Results There were a total of 12 403 leprosy relapse cases during 1949～ 1998 in China with a cumulative relapse rate of 3.28％ . Among them, 11 803 were relapsed after DDS monotherapy with a relapse rate of 3.83％ and 236 were after MDT with a relapse rate of 0.57％ . The relapse rate (0.84％ ) in PB cases which were previously treated with DDS monotherapy a half year was significantly higher than that (0.36％ ) in PB cases treated with MDT a half year. The relapse rate (0.37％ ) in MB cases which were previously treated with DDS monotherapy plus MDT also significantly higher than that (0.23％ ) in MB cases which were just treated with MDT two years. The proportions of cases with gradeⅡ disabilities and positive skin smears in relapse cases were 49.9％ and 69.3％ , respectively. Conclusion The peak of leprosy relapses after DDS monotherapy occurred during 1959～ 1988. The relapses after MDT started at the end of 1980s and may reach its peak in the next decades.

Objective To investigate the mechanism of inhibitor of calpain on hyperglycemia-induced apoptosis in cultured rat cardiomyocyte.Methods Cardiomyocytes were randomly divided into three groups (control,high glucose,and ALLN).MTT assay was used to detect the viability of cultured cardiomyocytes.Laser confocal microscopy was used to observe the mitochondrial permeable transition and membrane potential.The change of Caspase-3 activity in cardiomyocytes was detected by western blot.Results MTT assay showed that,after 72 h of hyperglycemia,the viability of cardiomyocytes was significantly declined (55％ ± 11％),and the viability in the ALLN pretreatment group was (70％ ± 15％) (P ＜0.05).After hyperglycemia,the mitochondrial permeable transition of cardiomyocyte was increased (30％ ± 15％ vs 60％ ± 11％,P ＜0.05),and membrane potential was declined.Hyperglycemia could increase the expression of cleaved capsase-3,while with pretreatment of ALLN the expression of cleaved caspase-3 was downregulation(0.42 ± 0.11 vs 0.21 ±0.12,P ＜0.05).Conclusions The calpain inhibitor can protect cardiomyocytes from apoptosis under the high glucose condition.

Objective To introduce a new method for correction of epicanthal folds, which could avoid obvious scar in medial canthus. Methods First, through upper and lower palpebral margin incisions, the connective and orbicularis oculi muscle dense fibers underlying epicanthal folds as well as the superficial head of medial canthal ligament were thoroughly released and excised. After repositioning the medial canthus, the redundant skin tissue was removed and then the incisions closed. Results 122 epicanthoplasties had been performed. Postsurgical scars were invisible in all cases. All patients were satisfied with operation results. No recurrence of epicanthal fold was observed. Conclusions The introduced method has advantages in avoiding scar formation and is an especially suitable approach for epicanthoplasty in Asian patients.

BACKGROUND:The thickness of ceramic materials plays a crucial role in the reappearance of veneer restorations. Due to the limited space for the construction of porcelain veneer, it is difficult to cover the abutment tooth color, and the final color after restorations is achieved through the overlapping of prosthetic restorations color and abutment tooth color. In recent years, there is little evidence on the effect of veneer materials on the color. OBJECTIVE:To evaluate the color matching of porcelain veneer restorations with different ceramic materials to shade tab. METHODS:Fifteen veneer restorations were fabricated by three ceramic materials (VITA Mark II, Ivoclar E.max LTCAD and Ivoclar E.max CAD Multi, A2 shade). Veneer restorations were controled at the thickness of 0.6 mm. The color parameters of veneer restorations were measured by Olympus Crystaleye against the natural color shade resin material substrate. The color differences were calculated between veneer restoration and shade tab (A2 shade) at the cervical, central and incisal sections, respectively. The color differences (?E values) were statisticaly analyzed using a one-way analysis of variance. RESULTS AND CONCLUSION:The color value of E.max CAD LT block was the closest one among the three blocks to the standard shade guide. The results of one-way analysis of variance for the ?E values showed that, there were significant differences between the cervical sections of the veneer restorations and the shade guide (P< 0.05). At the cervical sections, the ?E values between three kinds of blocks with the standard shade guide showed significant differences (P < 0.05); the differences were also significant in L values at the central and incisal sections, a values at the incisal sections and b value at the shoulder sections (P < 0.05). Our findings indicate that, there are significant differences in the color of porcelain veneer restorations with different ceramic materials to shade tab. The difference is also found among the three sections of the veneer restorations. In the clinical application, the final prosthesis color effects should be noted, which can change by surface staining and bonding technology.

Objective To investigate the way off-farm workers show bias on their own group ,rural residents and urban citizens .Method The participants were 78 off-farm workers from 18 to 25 years of age ;The scales and the modified affective priming paradigm were adopted to measure their explicit and implicit attitudes respectively on these groups through recording the participants' reaction on computer .Results (1)The order of three groups sorted by implicit scores in condition of group-relevant words as primes from high to low was urban citizens ,off-farm workers ,rural residents(0.169±0.217,-0.016±0.116,-1.209±1.686 respectively),but the order of explicit scores were reverse(0.7920±1.461,0.4469±1.514,07920±1.461 respectively),and both the difference between the implicit scores and the difference between explicit scores were very significant(between the implicit scores of group bias on off-farm workers and urban citizens:t=7.165,P＜0.01,and on rural residents:t=6.038,P＜0.01;between the explicit scores of group bias on off-farm workers and rural residents:t=9.666,P＜0.01,and on off-farm workers and urban citizens:t=7.828,P＜0.01).(2)The scale scores of group identify ,collective self-esteem and self-esteem were significantly related to the scale scores of group .bias on the off-farm workers and rural residents but not other scores(P＜0.01,P＜0.01,P＜0.05 respectively).Conclusion Although off-farm workers evaluated their own group and rural residents more positively than urban citizens in the obviously way ,they accepted the superiority of urban citizens .implicitly ,and the explicit group-bias was relative to self-esteem ,collective self-esteem and group identify.
