| 2 | The relationship between insulin resistance/β-cell dysfunction and diabetic retinopathy in Chinese patients with type 2 diabetes mellitus: the Desheng Diabetic Eye Study显示文摘AIM: To investigate the relationship between insulin resistance(IR)/β-cell dysfunction and diabetic retinopathy(DR) in Chinese patients with type 2 diabetes mellitus(T2 DM), and to explore further whether there were differences in the relationship among diabetic patients with higher and lower body mass index(BMI).METHODS: Cross-sectional study. A total of 1466 subjects with T2 DM were recruited in a local Desheng Community of urban Beijing from November 2009 to June 2012 for the cohort of Beijing Desheng Diabetic Eye Study. Standardized evaluation was carried out for each participant, including questionnaire, ocular and anthropometric examinations, and laboratory tests. Seven fields 30° color fundus photographs were used for DR grading according to the Early Treatment Diabetic Retinopathy Study protocols. Homeostatis Model Assessment(HOMA) method was employed for IR and β-cell function assessment.RESULTS: After excluding those participants who were treated with insulin(n=352) or had missing data of fasting insulin(n=96), and further excluding those with poor quality of retinal photographs(n=10), a total of 1008 subjects were included for the final analysis, 406(40.3%) were men and 602(59.7%) were women, age ranging from 34 to 86(64.87±8.28)y.Any DR(levels 14 and above) was present in 278(27.6%) subjects. After adjusting for possible covariates, the presenceof any DR did not correlate with HOMA IR [odds ratio(OR) 1.51, 95% confidence interval(CI) 0.87-2.61, P=0.14] or HOMA β-cell(OR 0.71, 95%CI 0.40-1.26, P=0.25). After stratification by BMI, the presence of any DR was associated positively with HOMA IR(OR 2.46, 95%CI: 1.18-5.12, P=0.016), and negatively with HOMA β-cell(OR 0.40, 95%CI: 0.19-0.87, P=0.021) in the group of patients with higher BMI(≥25 kg/m2). In the group of patients with lower BMI(<25 kg/m2), the presence of any DR was not associated with HOMA IR(OR 1.00, 95%CI: 0.43-2.33, P=1.00) or HOMA β-cell(OR 1.41, 95%CI: 0.60-3.32, P=0.43). CONCLUSION: The data suggest that higher IR and lower β-cell function are associated with the presence of DR in the subgroup of diabetic patients with higher BMI. However, this association is not statistically significant in diabetic patients with lower BMI. | Yun-Yun Li Xiu-Fen Yang Hong Gu Torkel Snellingen Xi-Pu Liu Ning-Pu Liu | 2018 | International Journal of Ophthalmology(English edition)2018,11,3: | 17 |
| 3 | C-reactive protein and diabetic retinopathy in Chinese patients with type 2 diabetes mellitus显示文摘AIM:To investigate the relationship between Creactive protein(CRP)and diabetic retinopathy(DR)in a cohort of Chinese patients with type 2 diabetes mellitus(T2DM).·METHODS:Community-based observational cohort study.There were 1131 participants recruited from November 2009 to September 2011 in Desheng community in urban Beijing.Patients diagnosed T2DM were recruited and underwent a standardized evaluation consisting of a questionnaire,ocular and anthropometric examinations and laboratory investigation.The presence and severity of DR were assessed by seven fields 30°color fundus photographs.Subjects were then classified into groups with no DR,any DR,or vision-threatening DR.CRP was analyzed from serum of study subjects.·RESULTS:A total of 1007 patients with T2DM were included for analysis,including 408(40.5%)men and 599(59.5%)women.The median CRP level was 1.5 mg/L for women and 1.1 mg/L for men(P=0.004,OR 0.37,95%CI0.18-0.74).After adjusting for possible covariates,higher levels of CRP were associated with lower prevalence of any DR(P=0.02,OR 0.55,95%CI 0.35-0.89),but not associated with vision-threatening DR(P=0.62,OR 0.78,95%CI 0.28-2.14).After stratification by sex,the inverseassociation between CRP and DR was found to be statistically significant in men(P=0.006,OR 0.35,95%CI0.16-0.73),but not in women(P=0.58,OR 0.88,95%CI0.29-1.16).·CONCLUSION:The data drawn from a Chinese population with T2DM suggest that increasing CRP levels may be inversely associated with development of DR. | Xiu-Fen Yang Yu Deng Hong Gu Apiradee Lim Torkel Snellingen Xi-Pu Liu Ning-Li Wang Amitha Domalpally Ronald Danis Ning-Pu Liu | 2016 | International Journal of Ophthalmology(English edition)2016,9,1: | 6 |
| 4 | Use of Cataract Surgery in Urban Beijing: a Post Screening Follow-up of the Elderly with Visual Impairment due to Age-related Cataract显示文摘Objective To understand the perception for the use of cataract surgical services in a population of acceptors and non-acceptors of cataract surgery in urban Beijing. Methods From a community-based screening program a total of 158 patients with presenting visual acuity of less than 6/18 on either eye due to age-related cataract were informed about the possibility of surgical treatment. These patients were interviewed and re-examined 36 to 46 months after initial screening. The main reasons for not accepting surgery were obtained using a questionnaire. Vision function and vision-related quality of life scores were assessed in those who received and did not receive surgery. Results At the follow-up examination 116 of the 158 patients were available and 36(31.0%) had undergone cataract surgery. Cases who chose surgery had higher education level than those who did not seek surgery(OR=2.64, 95% CI: 1.08-6.63, P=0.02). There were no significant differences in vision function(P=0.11) or quality of life scores(P=0.16) between the surgery group and the non-surgery group. Main reasons for not having surgery included no perceived need(50.0%), feeling of being 'too old'(19.2%), and worry about the quality of surgery(9.6%). Cost was cited by 1(1.9%) subject as the main reason for not seeking surgery.Conclusions The data suggest that in China's capital urban center for patients with moderate visual impairment there is a relative low acceptance rate of cataract surgery, mainly due to people's perception of marginal benefits of surgery. Cost is not a determining factor as barrier to undergo surgery and patients with poorer education are less likely to undertake surgery. | Xue-tao Ren Torkel Snellingen Hong Gu Sawitri Assanangkornchai Yan-hong Zou Virasakdi Chongsuvivatwong Apiradee Lim Wei Jia Xi-pu Liu Ning-pu Liu | 2015 | Chinese Medical Sciences Journal2015,30,1: | 5 |
| 5 | Association of C(-106)T Polymorphism in Aldose Reductase Gene with Diabetic Retinopathy in Chinese Patients with Type 2 Diabetes Mellitus显示文摘Objective To identify the possible association between C(-106)T polymorphism of the aldose reductase(ALR) gene and diabetic retinopathy(DR) in a cohort of Chinese patients with type 2 diabetes mellitus(T2DM).Methods From November 2009 to September 2010,patients with T2DM were recruited and assigned to DR group or diabetic without retinopathy(DWR) group according to the duration of diabetes and the grading of 7-field fundus color photographs of both eyes.Genotypes of the C(-106)T polymorphism(rs759853) in ALR gene were analyzed using the MassARRAY genotyping system and an association study was performed.Results A total of 268 T2DM patients(129 in the DR group and 139 in the DWR group) were included in this study.No statistically significant differences were observed between the 2 groups in the age of diabetes onset(P=0.10) and gender(P=0.78).The success rate of genotyping for the study subjects was 99.6%(267/268),with one case of failure in the DR group.The frequencies of the T allele in the C(-106)T polymorphism were 16.0%(41/256) in the DR group and 19.4%(54/278) in the DWR group(P=0.36).There was no significant difference in the C(-106)T genotypes between the 2 groups(P=0.40).Compared with the wild-type genotype,odds ratio(OR) for the risk of DR was 0.7(95% CI,0.38-1.3) for the heterozygous CT genotype and 0.76(95% CI,0.18-3.25) for the homozygous TT genotype.The risk of DR was positively associated with microalbuminuria(OR=4.61;95% CI,2.34-9.05) and insulin therapy(OR=3.43;95% CI,1.94-6.09).Conclusions Microalbuminuria and insulin therapy are associated with the risk of DR in Chinese patients with T2DM.C(-106)T polymorphism of the ALR gene may not be significantly associated with DR in Chinese patients with T2DM. | Yu Deng Xiu-fen Yang Hong Gu Apiradee Lim Munkhtulga Ulziibat Torkel Snellingen Jun Xu Kai Ma Ning-pu Liu | 2014 | Chinese Medical Sciences Journal2014,29,1: | 4 |
| 6 | Helicobacter species and common gut bacterial DNA in gallbladder with cholecystitis显示文摘AIM:To analyze the association between Helicobacter spp. and some common gut bacteria in patients with cholecystitis. METHODS:A nested-polymerase chain reaction (PCR), specif ic to 16S rRNA of Helicobacter spp. was performed on paraff in-embedded gallbladder samples of 100 cholecystitis and 102 control cases. The samples were also analyzed for some common gut bacteria by PCR. Positive samples were sequenced for species identif ication. RESULTS: Helicobacter DNA was found in seven out of 100 cases of acute and chronic cholecystitis. Sequence analysis displayed Helicobacter pullorum (H. pullorum) in six cases and Helicobacter pylori in one; H. pullorum was only found in cases with metaplasia. Control sam-ples were negative for Helicobacter spp. and some common gut bacteria. There was a signif icant difference (P=0.007) between cholecystitis and control samples for Helicobacter DNA.CONCLUSION:A possible relationship was detected between Helicobacter DNA and cholecystitis. Further serological and immunohistochemical studies are needed to support these data. | Peren H Karagin Unne Stenram Torkel Wadstrm sa Ljungh | 2010 | World Journal of Gastroenterology2010,16,38: | 3 |
| 7 | The Beijing Desheng Diabetic Eye Study:rationale,design,methodology and baseline data显示文摘AIM: To present the rationale, design, methodology, and the baseline data of the Beijing Desheng Diabetic Eye Study(BDDES), and to determine the prevalence of diabetic retinopathy(DR) and possible risk factors in patients with type 2 diabetes mellitus(T2DM) in an urban community of Beijing, China.METHODS: Community-based prospective cohort study of persons diagnosed with T2DM aged 30 y or older. The main variables of interest are the presence and progression of DR as determined by the standardized ETDRS grading of seven fields fundus photographs. The presence and severity of DR were analyzed for possible correlations to non-genetic and genetic dispositions.RESULTS: A total of 1438 participants with data available for analysis, the prevalence of any DR was 35.4%. The prevalence of mild non-proliferative diabetic retinopathy(NPDR), moderate NPDR, severe NPDR, and proliferative diabetic retinopathy was 27.7%, 2.6%, 0.5% and 4.5%, respectively. By multiple logistic regression analysis, risk factors for the presence of any DR included male(P=0.031), lower income level(P=0.011), lower education background(P=0.022), longer duration of diabetes(P=0.001), younger age at diabetic onset(P=0.001), higher systolic blood pressure(P=0.007), higher glycosylated hemoglobin A1 c levels(P=0.001), high albuminuria(P=0.03), and use of insulin(P<0.001). For vision-threatening DR, four factors were significant: younger age at diabetic onset(P<0.001),higher systolic blood pressure(P=0.042), high albuminuria(P<0.001), and use of insulin(P<0.001). CONCLUSION: The BDDES is the first large-scale ongoing cohort study of a Chinese urban population of persons with type 2 diabetes. Using standardized grading system comparable to large cohort studies from western populations, our baseline data shows that the prevalence of DR and major risk factors in this Chinese ethnic population are comparable to that found in the western population studies. | Yun-Yun Li Xiu-Fen Yang Hong Gu Xi-Pu Liu Torkel Snellingen Ning-Pu Liu | 2018 | International Journal of Ophthalmology(English edition)2018,11,1: | 3 |
| 8 | Interferon-γ inhibits ghrelin expression and secretion via a somatostatin-mediated mechanism显示文摘AIM:To investigate if and how the proinflammatory cytokine interferon γ(IFNγ) affects ghrelin expression in mice.METHODS:The plasma concentration of ghrelin,andgastric ghrelin and somatostatin expression,were examined in wild-type mice and mice infected with Helicobacter pylori(H.pylori).Furthermore,ghrelin expression was examined in two achlorhydric mouse models with varying degrees of gastritis due to bacterial overgrowth.To study the effect of IFNγ alone,mice were given a subcutaneous infusion of IFNγ for 7 d.Finally,the influence of IFNγ and somatostatin on the ghrelin promoter was characterized.RESULTS:H.pylori infection was associated with a 50% reduction in ghrelin expression and plasma concentration.Suppression of ghrelin expression was inversely correlated with gastric inflammation in achlorhdyric mouse models.Subcutaneous infusion of IFNγ suppressed fundic ghrelin mRNA expression and plasma ghrelin concentrations.Finally,we showed that the ghrelin promoter operates under the control of somatostatin but not under that of IFNγ.CONCLUSION:Gastric infection and inflammation is associated with increased IFNγ expression and reduced ghrelin expression.IFNγ does not directly control ghrelin expression but inhibits it indirectly via somatostatin. | Jesper AB Strickertsson Kristina BV DΦssing Anna JM Aabakke Hans-Olof Nilsson Thomas VO Hansen Ulrich Knigge Andreas Kjr Torkel Wadstrm Lennart Friis-Hansen | 2011 | World Journal of Gastroenterology2011,17,26: | 2 |

| 11 | Agglutination of Helicobacter pylori coccoids by lectins显示文摘AIM To study the agglutination pattern ofHelicobacter pylori coccoid and spiral forms.METHODS Assays of agglutination andagglutination inhibition were applied usingfifteen commercial lectins.RESULTS Strong agglutination was observedwith mannose-specific Concanavalin A(Con A),fucose-specific Tetragonolobus purpureas(Lotus A)and N-acetyl glucosamine-specificTriticum vulgaris(WGA)lectins.Mannose andfucose specific lectins were reactive with allstrains of H.pylori coccoids as compared to thespirals.Specific carbohydrates,glycoproteinsand mucin were shown to inhibit H.pylorilectin-agglutination reactions.Pre-treatment ofthe bacterial cells with formalin and sulphuricacid did not alter the agglutination patterns withlectins.However,sodium periodate treatment ofbacterial cells were shown to inhibitagglutination reaction with Con A,Lotus A andWGA lectins.On the contrary,enzymatictreatment of coccoids and spirals did not showmarked inhibition of H.pylori-lectinagglutination.Interestingly,heating of H.pylori cells at 60℃ for 1 hour was shown toaugment the agglutination with all of the lectinstested.CONCLUSION The considerable differences inlectin agglutination patterns seen among the twodifferentiated forms of H.pylori might beattributable to the structural changes during theevents of morphological transformation,resulting in exposing or masking some of the sugar residues on the cell surface.Possibility ofvarious sugar residues on the cell wall of thecoccoids may allow them to bind to differentcarbohydrate receptors on gastric mucus andepithelial cells.The coccoids with adherencecharacteristics like the spirals could aid in thepathogenic process of Helicobacter infection.This may probably lead to different clinicaloutcome of H.pylori associated gastroduodenaldisease. | Mar Mar Khin Jie Song Hua Han Cong Ng Torkel Wadstrm Bow Ho | 2000 | World Journal of Gastroenterology2000,6,2: | 1 |
| 12 | Measurement of macular pigment optical density among healthy Chinese people and patients with early-stage age-related macular degeneration显示文摘AIM: To measure the macular pigment optical density(MPOD) in healthy Chinese people and patients with early age-related macular degeneration(AMD).·METHODS: Cross-sectional population based study.Demographic and lifestyle characteristics were ascertained by questionnaire. A food frequency questionnaire was completed for all participants.Participants underwent general physical and ophthalmic examinations and MPOD was measured by heterochromatic flicker photometry. Foveal architecture was measured by optical coherence tomography.·RESULTS: MPOD of 225 participants(122 healthy and 103 early AMD) was 0.48 ±0.18. Patients with early AMD(0.52 ±0.19) tended to have higher MPOD levels than healthy people(0.47 ±0.17), but the difference was not statistically significant(P =0.06). Participants with carrot or corn oil intake every week tended to have higher levels of MPOD(P =0.002 and 0.008 respectively) while those with corn intake had relatively lower level of MPOD(P =0.01). MPOD increased with the center foveal thickness(P =0.01).· CONCLUSION: Our findings show that there is no statistically significant association between MPOD and early AMD in the studied population. MPOD is related to center foveal thickness and diets would influence MPOD levels. | Xue-Tao Ren Hong Gu Xu Han Jun-Yan Zhang Xue Li Xiu-Fen Yang Jun Xu Torkel Snellingen Xi-Pu Liu Ning-Li Wang Ning-Pu Liu | 2015 | International Journal of Ophthalmology(English edition)2015,8,6: | 1 |
