ABSTRACT
Viscum coloratum(Komn.)Nakai is a well-known medicinal hemiparasite widely distributed in Asia.The synthesis and accumulation of its metabolites are affected by both environmental factors and the host plants,while the latter of which is usually overlooked.The purpose of this study was to comprehensively evaluate the effects of host and habitat on the metabolites in V.coloratum through multiple chemical and biological approaches.The metabolite profile of V.coloratum harvested from three different host plants in two habitats were determined by multiple chemical methods including high-performance liquid chromatography-ultraviolet(HPLC-UV),gas chromatography-flame ionization detector(GC-FID)and ultra-performance liquid chromatography quadrupole time of flight mass spectrometry(UPLC-QTOF/MS).The differences in antioxidant efficacy of V.coloratum were determined based on multiple in vitro models.The multivariate statistical analysis and data fusion strategy were applied to analyze the dif-ferences in metabolite profile and antioxidant activity of V.coloratum.Results indicated that the metabolite profile obtained by various chemical approaches was simultaneously affected by host and environment factors,and the environment plays a key role.Meanwhile,three main differential metab-olites between two environment groups were identified.The results of antioxidant assay indicated that the environment has greater effects on the biological activity of V.coloratum than the host.Therefore,we conclude that the integration of various chemical and biological approaches combined with multivariate statistical and data fusion analysis,which can determine the influences of host plant and habitat on the metabolites,is a powerful strategy to control the quality of semi-parasitic herbal medicine.
ABSTRACT
OBJECTIVE@#The association between neutrophil-to-lymphocyte ratio (NLR) with subclinical macrovascular and microvascular diseases has been less investigated. We sought to examine the association between NLR and new-onset subclinical macrovascular and microvascular abnormalities in the Chinese population.@*METHODS@#From a community cohort, we included 6,430 adults aged ≥ 40 years without subclinical macrovascular and microvascular diseases at baseline. We measured subclinical macrovascular and microvascular abnormalities separately using the ankle-brachial index (ABI), brachial-ankle pulse wave velocity (baPWV), and albuminuria.@*RESULTS@#During a mean follow-up of 4.3 years, 110 participants developed incident abnormal ABI, 746 participants developed incident elevated baPWV, and 503 participants developed incident albuminuria. Poisson regression analysis indicated that NLR was significantly associated with an increased risk of new-onset abnormal ABI, elevated baPWV, and albuminuria. Compared to overweight/obese participants, we found a much stronger association between NLR and subclinical vascular abnormalities in participants with normal weight. Furthermore, we found an interaction between the NLR and body mass index (BMI) on the risk of new-onset abnormal ABI ( P for interaction: 0.01).@*CONCLUSION@#NLR was associated with subclinical macrovascular and microvascular diseases in the Chinese population. Furthermore, in participants with normal weight, the association between NLR and subclinical vascular abnormalities was much stronger.

Objective@#The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population.@*Methods@#The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models.@*Results@#A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices).@*Conclusion@#An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

Objective: To investigate the histopathological and hematological changes in reoperation of recurrent chronic rhinosinusitis with nasal polyps (CRSwNP). Methods: A total of 41 patients with CRSwNP who underwent two consecutive endoscopic sinus surgeries in Peking Union Medical College Hospital from February 1999 to April 2019 were included retrospectively, including 25 males and 16 females, aged (40.7±13.6) years at the former surgery and (47.0±13.2) years at the recurrent surgery. The peripheral blood cell count results were collected. Differential inflammatory cells in nasal polyp tissue sections were counted and characteristics of tissue remodeling were scored. Paired t test was used to compare the hematological and histological data of the two surgeries in the same cohort. Spearman's rank correlation coefficient was used to determine the correlation between tissue and peripheral blood eosinophil contents. Results: In histopathological tissue sections of nasal polyps, the mean tissue eosinophil, lymphocyte and total inflammatory cell counts per high power field significantly decreased (54.04±34.67 vs 76.97±65.59, 35.27±16.61 vs 50.01±26.94, 128.88±41.32 vs 176.38±80.59, t value was 2.413, 2.923, 3.445, respectively, all P<0.05), whereas the percentages of different inflammatory cell types remained unchanged when comparing the recurrent surgery with the former surgery. There was a significant reduction of basement membrane thickness and goblet cell hyperplasia score in the recurrent surgery (1.29±0.84 vs 2.00±0.84, 1.81±1.31 vs 2.44±1.10, t value was 5.367, 2.714, respectively, all P<0.05). Subgroup analysis suggested that changes in asthmatic cases, younger cases and cases without previous surgery were more remarkable than non-asthmatics, older cases and cases with previous surgery, respectively. There was no significant change in peripheral white blood cell counts and differential cell percentages, except a small increase of blood monocyte percentage. Correlation analysis showed that tissue eosinophil content correlated positively with blood eosinophil content at each surgery. Conclusions: In the recurrent surgery of CRSwNP, tissue eosinophil, lymphocyte and total inflammatory cell counts decrease significantly compare with that of the former surgery. The histological inflammatory load decreases with improvement of tissue remodeling, which could be attributed to the integrated treatment with surgery and medications.

Objective: To investigate the difference of concentrations of specialized pro-resolving mediators (SPMs) derived from fatty acids in eosinophilic chronic rhinosinusitis with nasal polyps (ECRSwNP) and non-eosinophilic chronic rhinosinusitis with nasal polyps (nECRSwNP). Methods: A total of 36 patients with bilateral chronic rhinosinusitis with nasal polyps (CRSwNP) who underwent endoscopic nasal surgeries in Peking Union Medical College Hospital from May 2019 to September 2020 were enrolled, including 27 males and 9 females, with the age from 13 to 67 years. There were 23 cases of ECRSwNP and 13 cases of nECRSwNP. At the same time, 12 control subjects were enrolled. The concentrations of multiple SPMs, including lipoxins (LXA4 and LXB4), resolvins (RvD1, RvD2, RvD3, RvD5 and RvE1), protectins (PDX) and maresins (Mar-1) in nasal polyps with different histological subtypes and normal nasal mucosa were analyzed using liquid chromatography-tandem mass spectrometry. The concentrations of SPMs between groups were compared using Mann-Whitney U test. Spearman's rank correlation coefficient was used to measure the correlation between the concentrations of SPMs in nasal polyps and tissue eosinophil counts. Results: The concentrations of RvD2, RvD3, RvD5, LXA4, LXB4, Mar-1 and PDX in ECRSwNP group were significantly higher than that in controls (Z value was -2.276, -2.313, -3.371, -2.094, -2.051, -3.104 and -2.294, respectively, all P<0.05). The concentrations of RvD2, RvD5, Mar-1 and PDX in ECRSwNP group were significantly higher than those in nECRSwNP group (Z value was -2.175, -2.289, -2.243 and -2.124, respectively, all P<0.05). There was no significant difference in all these SPMs between nECRSwNP and controls (all P>0.05). The concentrations of RvD2, RvD3, RvD5, LXB4, Mar-1 and PDX in nasal polyps correlated positively with tissue eosinophil counts (r value was 0.443, 0.436, 0.371, 0.502, 0.340 and 0.386, respectively, all P<0.05). Conclusions: A varienty of SPMs are elevated in ECRSwNP. Dysregulation of fatty acid metabolism might play an important role in the chronic inflammation of ECRSwNP.

Objective@#Liver fibrosis is an important predictor of mortality in nonalcoholic fatty liver disease (NAFLD). Peripheral artery disease (PAD) and liver fibrosis share many common metabolic dysfunctions. We aimed to explore the association between PAD and risk of fibrosis deterioration in NAFLD patients.@*Methods@#The study recruited 1,610 NAFLD patients aged ≥ 40 years from a well-defined community at baseline in 2010 and followed up between August 2014 and May 2015. Fibrosis deterioration was defined as the NAFLD fibrosis score (NFS) status increased to a higher category at the follow-up visit. PAD was defined as an ankle-brachial index of 1.40.@*Results@#During an average of 4.3 years' follow-up, 618 patients progressed to a higher NFS category. PAD was associated with 92% increased risk of fibrosis deterioration [multivariable-adjusted odds ratio ( ): 1.92, 95% confidence interval ( ): 1.24, 2.98]. When stratified by baseline NFS status, the for progression from low to intermediate or high NFS was 1.74 (95% : 1.02, 3.00), and progression from intermediate to high NFS was 2.24 (95% : 1.05, 4.80). There was a significant interaction between PAD and insulin resistance (IR) on fibrosis deterioration ( for interaction = 0.03). As compared with non-PAD and non-IR, the coexistence of PAD and IR was associated with a 3.85-fold (95% : 2.06, 7.18) increased risk of fibrosis deterioration.@*Conclusion@#PAD is associated with an increased risk of fibrosis deterioration in NAFLD patients, especially in those with IR. The coexistence of PAD and IR may impose an interactive effect on the risk of fibrosis deterioration.

OBJECTIVE@#The association between lipoprotein (a) [Lp(a)] levels and metabolic syndrome (MetS) remains uncertain, especially in the Asian population. The purpose of this study was to demonstrate the association between Lp(a) levels and MetS in a middle-aged and elderly Chinese cohort.@*METHODS@#A cross-sectional study of 10,336 Chinese adults aged 40 years or older was conducted in Jiading District, Shanghai, China. Logistic regression analysis was used to evaluate the association between serum Lp(a) levels and MetS.@*RESULTS@#In the overall population, 37.5% of participants had MetS. Compared with individuals in the lowest quartile of serum Lp(a) levels, those in the highest quartile had a lower prevalence of MetS (30.9% vs. 46.9%, P for trend < 0.0001). Multivariate logistic regression analyses showed that compared with participants in the bottom quartile of serum Lp(a) levels, those in the top quartile had decreased odds ratio (OR) for prevalent MetS [multivariate-adjusted OR 0.45 (95% confidence interval 0.39-0.51); P < 0.0001]. Additionally, Lp(a) level was conversely associated with the risk of central obesity, high fasting glucose, high triglycerides, and low HDL cholesterol, but not with hypertension. Stratified analyses suggested that increasing levels of Lp(a) was associated with decreased risk of MetS in all the subgroups.@*CONCLUSION@#Serum Lp(a) level was inversely associated with the risk of prevalent MetS in a middle-aged and elderly Chinese cohort.

OBJECTIVE@#Ideal cardiovascular health (CVH) could predict a lower risk of developing cardiovascular diseases. This study was conducted to investigate the association between ideal CVH and subclinical atherosclerosis in a population cohort of Chinese adults aged ⪖ 40 years.@*METHODS@#This study was designed as a cross-sectional analysis of 8,395 participants who had complete data at baseline and a prospective analysis of 4,879 participants who had complete data at 4.3 years of follow-up. Ideal CVH metrics were defined according to the American Heart Association. Subclinical atherosclerosis was evaluated by plaques in carotid arteries, carotid intima-media thickness (CIMT), brachial-ankle pulse wave velocity (baPWV), and urinary albumin-to-creatinine ratio (UACR).@*RESULTS@#Both the prevalence and incidence of atherosclerosis measures were found to be decreased with increasing numbers of ideal CVH metrics at baseline (all P values for trend < 0.01). The levels of CIMT and UACR at follow-up showed an inverse and significant association with the numbers of ideal CVH metrics at baseline (both P values for trend < 0.05) but a borderline significant association with baPWV (P for trend = 0.0505). Taking participants with 0-1 ideal metric as reference, we found that participants with 5-6 ideal metrics had significantly lower risks of developing carotid plaques (odds ratio, OR = 0.46; 95% confidence interval, CI 0.27-0.79), increased CIMT (OR = 0.60; 95% CI 0.42-0.84), and increased baPWV (OR = 0.57; 95% CI 0.34-0.97) after full adjustments. A significant interactive effect of age and CVH was detected on CIMT and baPWV progression (both P values for interaction < 0.05).@*CONCLUSION@#The numbers of ideal CVH metrics showed a significant and inverse association with the risk of developing subclinical atherosclerosis in middle-aged and elderly Chinese adults, whereas its dose-response effect was attenuated in individuals aged ≥ 60 years and partially weakened in male participants.

OBJECTIVE@#The objective of this study is to determine whether coronary atherosclerotic plaque composition is associated with cardiovascular disease (CVD) risk in Chinese adults.@*METHODS@#We performed a cross-sectional analysis in 549 subjects without previous diagnosis or clinical symptoms of CVD in a community cohort of middle-aged Chinese adults. The participants underwent coronary computed tomography (CT) angiography for the evaluation of the presence and composition of coronary plaques. CVD risk was evaluated by the Framingham risk score (FRS) and the 10-year atherosclerotic cardiovascular disease (ASCVD) risk score.@*RESULTS@#Among the 549 participants, 267 (48.6%) had no coronary plaques, 201 (36.6%) had noncalcified coronary plaques, and 81 (14.8%) had calcified or mixed coronary plaques. The measures of CVD risk including FRS and ASCVD risk score and the likelihood of having elevated FRS significantly increased across the groups of participants without coronary plaques, with noncalcified coronary plaques, and with calcified or mixed coronary plaques. However, only calcified or mixed coronary plaques were significantly associated with an elevated ASCVD risk score [odds ratio (OR) 2.41; 95% confidence interval (CI) 1.09-5.32] compared with no coronary plaques, whereas no significant association was found for noncalcified coronary plaques and elevated ASCVD risk score (OR 1.25; 95% CI 0.71-2.21) after multivariable adjustment.@*CONCLUSION@#Calcified or mixed coronary plaques might be more associated with an elevated likelihood of having CVD than noncalcified coronary plaques.

OBJECTIVE@#To examine the association between serum uric acid levels and cardiovascular disease risk among individuals without diabetes.@*METHODS@#We investigated the association between serum uric acid levels and the risk of prevalent cardiometabolic diseases, 10-year Framingham risk for coronary heart disease, and 10-year risk for atherosclerotic cardiovascular diseases (ASCVD) among 8,252 participants aged ⪖ 40 years without diabetes from Jiading district, Shanghai, China.@*RESULTS@#Body mass index, waist circumference, blood glucose, glycated hemoglobin, blood pressure, and serum lipids increased progressively across the sex-specific quartiles of uric acid (all P trend < 0.05). Compared with individuals in the lowest quartile, those in the higher quartiles had a significantly higher prevalence of obesity, hypertension, and dyslipidemia (all P trend < 0.05). A fully adjusted logistic regression analysis revealed that individuals in the highest quartile had an increased risk of predicted cardiovascular disease compared with those in the lowest quartile of uric acid. The multivariate adjusted odds ratios (ORs) [95% confidence intervals (CIs)] for the highest quartiles for high Framingham risk were 3.00 (2.00-4.50) in men and 2.95 (1.08-8.43) in women. The multivariate adjusted ORs (95% CIs) for the highest quartile for high ASCVD risk were 1.93 (1.17-3.17) in men and 4.53 (2.57-7.98) in women.@*CONCLUSION@#Serum uric acid level is associated with an increased risk of prevalent obesity, hypertension, dyslipidemia, 10-year Framingham risk for coronary heart disease, and 10-year risk for ASCVD among Chinese adults without diabetes.

This current cross-sectional study investigates the relationship between thyroid hormones and peripheral artery disease (PAD) among euthyroid Chinese population aged 40 years and above. Serum free triiodothyronine (FT3), free thyroxin (FT4), thyroid-stimulating hormone (TSH), and thyroid antibodies were measured. PAD was defined as ankle-brachial index (ABI) < 0.9. There were 91 (2.9%) PAD cases among the 3,148 euthyroid study participants. Participants in the highest quartile of FT3 and free-triiodothyronine-to-free-thyroxin (FT3/FT4 ratio) had a decreased risk of prevalent PAD (multivariate-adjusted odds ratio, 95% confidence interval: 0.32, 0.15-0.62, P for trend = 0.01 and 0.31, 0.13-0.66, P for trend = 0.004, respectively) compared to those in the lowest quartile. To conclude, FT3 levels and the FT3/FT4 ratio was inversely associated with prevalent PAD in euthyroid Chinese population aged 40 years and above.

Objective To investigate and analyze the situation of urban and rural neglected children aged 3-6,in China,so as to provide basis for the analysis and comparison on relevant risk factors.Methods 1163 urban children aged 3-6 (with 49.6% males and 4.5% with minority ethnicity) were investigated from 25 cities of 14 provinces,autonomous regions and municipalities in the whole country.Multi-stage stratified cluster sampling method was used.Again,using the same sampling method,4096 rural children (of whom 50.6% were males with 6.2% as minorities) were chosen from 26 cities of 10 provinces or municipalities.Identification of children being neglected was based on “Child Neglect Evaluation Norms of Children Aged 3-6 Years in Urban/Rural China”.SPSS-Windows 13.0 was employed for data analysis.Scores,frequency/degrees,age,sex and types (physical,emotional,educational,safety,medical and social) of children under negligence on every group of the regions,were calculated.x2 test (Chi-Square) and Analysis of variance (ANOVA) were processed to determine the significance of their differences.Results The overall frequencies of negligence were 28.0% and 53.7% respectively among the urban and rural children aged 3-6,while the total degrees of negligence were 42.2 and 44.4 respectively.Significant difference was found between children from the urban and the rural areas (P<0.05).Significant difference was also found between urban and rural children on every age group (P<0.05).The frequencies of negligence among males were 32.6% and 55.9% respectively in urban and rural areas while among females,the figures appeared to be 23.7% and 51.6% respectively.The degrees of negligence were 42.7 and 44.6 among male while 41.8 and 44.3 among female children,in the urban or rural areas.Significant differences were found on male or female between urban and rural groups (P<0.05).Frequencies of negligence in urban children aged 3-6 for the six types were from 5.1% to 12.9%,with the frequency in rural areas as 13.1%-26.6%.Significant difference was found between urban and rural group for any other type (P<0.05),in addition to the safety type.The degrees of negligence in urban children aged 3-6 for the different type were between 39.4 and 43.4,while in the rural areas as from 36.5 to 48.2,with significant difference for every type (P<0.05).The degrees of negligence related to education,emotion,or physical strength were more serious on children from the urban than from the rural areas.The highest frequency of child negligence was seen in the single-parent families on both urban and rural groups (42.9% and 60.0% respectively),with no significant difference found (P>0.05).The urban and rural children aged 3-6 were mainly involved in single item of negligence,with incidence rates as 16.5% and 22.7% and proportions as 58.9% and 45.1% respectively,despite the factors as age or sex.Conclusion There were large differences on the situation of negligence between the urban and rural children aged 3-6.The frequencies and degrees of negligence in every age group and different sex for children living in the rural areas were higher than those urban children.The frequency of negligence among boys was higher than girls for both urban and rural areas.The rural children had suffered more serious negligence than the urban children at any other type,in addition to the ‘ safety'.Both urban and rural children had the highest frequency of negligence in single-parent family,and were mainly suffered from single item of negligence.
ABSTRACT
Objective To develop the National Norms of Negligence (NNN) for rural children aged 0 to 35 months.Methods According to multi-stage stratified cluster sampling principle,10 provinces or municipalities (Jilin,Shaanxi,Shanxi,Beijing,Anhui,Jiangsu,Hunan,Hubei,Yunnan,Chongqing) in China were selected.A national research group was formed collaboratively.A questionnaire was designed by ourselves.According to several statistical analysis methods,such as item,factor and reliability analysis etc.we determined the norm.The evaluation criteria of the scale were determined by percentile method.Finally,the reliability and validity of the norm were evaluated.Results In total,2310 children were surveyed,in which the effective sample were 2227,with an effective rate as 96.4%.The scale consisted of 6 neglected dimensions and 65 items in total.The total Cronbach's α coefficient of the scale was 0.903,with the split-half reliability coefficient as 0.829,the parallel reliability as 0.720 and the re-test reliability as 0.678,respectively.The total neglect cut-off score of this scale was 139.Conclusion The scale seemed to have perfect stability and reliability and all the statistical indicators met the psychometric demands.
ABSTRACT
<p><b>OBJECTIVE</b>To compare the clinical outcomes between China made sirolimus-eluting stents (SES) and bare metal stents (BMS) implantation in patients with acute myocardial infarction (AMI).</p><p><b>METHODS</b>Consecutive patients with AMI underwent primary percutaneous coronary intervention (PCI) were randomly divided into SES group (n = 87) and BMS group (n = 86). The incidence of major adverse cardiac events (MACE including death, reinfarction, in-stent thrombosis, restenosis rate, target vessel revascularization) up to 6 months post PCI were assessed.</p><p><b>RESULTS</b>Postprocedure vessel patency, enzymatic release, cardiac function, and the incidence of short-term MACE were similar between the two groups (all P > 0.05). Two in-stent thrombosis was diagnosed in the SES group and bare stents group respectively (2.4% vs. 2.3%, P > 0.05). At 6 months, In-stent restenosis rate (4.5% vs. 40.0%, P < 0.01) and the in-segment restenosis rate (6.8% vs. 44.9%, P < 0.01) as well as MACE (8.0% vs. 24.4%, P < 0.01), which is mainly due to a marked reduction in the risk of target vessel revascularization (3.4% vs. 11.6%, P < 0.05) were significantly lower in SES group compared to BMS group.</p><p><b>CONCLUSION</b>The China made SES were not associated with an increased risk of in-stent thrombosis but significantly reduced restenosis rate and MACE at 6 months post primary angioplasty in patients with AMI.</p>

<p><b>BACKGROUND</b>Subcutaneous absorption is accelerated by the monomeric conformation of insulin Aspart, which provides good glycemic control with a lower risk of hypoglycemia and less body weight increase. In the present study we investigated the efficacy and safety of a rapid-acting human insulin analogue (insulin Aspart) delivered with continuous subcutaneous insulin infusion (CSII) into Chinese diabetic patients.</p><p><b>METHODS</b>A total of 21 patients with type 1 or type 2 diabetes were recruited for the 2-way cross-over, open-labeled trial, and then randomized to Group A (n = 10, treated with insulin Aspart) or Group B (n = 11, treated with Novolin R). Insulin Aspart and Novolin R were administered by CSII. Capillary glucose concentrations were measured at 8 time points, pre-prandial and postprandial, bedtime (10 pm), midnight (2 am) every day during the treatment.</p><p><b>RESULTS</b>The average capillary glucose profiles for the day were much better controlled in Group A than in Group B (P < 0.01). The blood glucose levels were particularly better controlled in Group A than in Group B at pre-breakfast ((6.72 +/- 1.24) mmol/L vs (7.84 +/- 1.58) mmol/L, P = 0.014), post-breakfast ((8.96 +/- 2.41) mmol/L vs (11.70 +/- 3.11) mmol/L, P = 0.0028), post-supper ((8.15 +/- 2.10) mmol/L vs (10.07 +/- 2.36) mmol/L, P = 0.008), bed time ((7.73 +/- 1.72) mmol/L vs (9.39 +/- 2.05) mmol/L, P = 0.007) and midnight ((6.32 +/- 1.16) mmol/L vs (7.48 +/- 1.36) mmol/L, P = 0.0049). There was no significant difference in the frequency of hypoglycemic episodes between the two groups.</p><p><b>CONCLUSION</b>Insulin Aspart results in better control of blood glucose levels than regular human insulin (Novolin R) in diabetic patients during delivery by CSII.</p>

OBJECTIVE: To compare the characteristics of over weight and obesity subjects defined by three criteria: World Health Organization (WHO) in 1999, the National Cholesterol Education Program Adult Treatment Panel Nll (NCEP-ATP II ) in 2001, and the International Diabetes Federation (IDF) in 2005. METHODS: Medical history collection, physical examination, oral glucose tolerance test ( OGTT) , and frequently sampled intravenous glucose tolerance test (FSIGTT) were performed in 371 subjects with body mass index (BMI)> or =23 kg/m(2). Fasting blood samples were taken to test lipid profiles, urea acid level and so on. Data was analyzed including comparison and relationship statistics. RESULTS: Data from FSIGTT showed that insulin resistance existed in all over weight and obesity subjects. The relationship between waist and sensitivity index (SI) was superior than that between BMI and SI ( r = - 0. 198 and r = - 0. 194, P < 0. 001). Totally 107 subjects (28. 8%) did not meet any definitions, 187 (50. 4%) met ATP definition, 98 (26. 4%) met WHO definition, and 234 (63. 1% ) met IDF definition. ATP and IDF definitions had the highest coincidence rate (70. 3% ) , and subjects in these two groups almost had basically the same manifestations. The age of onset in WHO group was higher than those in other two groups. Meanwhile, subjects in the WHO group was characterized by lower BMI, higher hyperlipidemia, and significantly increased fasting and postprandial blood glucose level. The MS component scores were positively correlated with age, BMI, waist, and waist-to-hip ratio (WHR) , and were negatively correlated with SI. However, no correlation was found between MS component scores and gender, fat% , or acute insulin response to glucose index. CONCLUSIONS: Some of over weight and obesity subjects only have insulin resistance and have no metabolism syndrome. The group defined by IDF criteria of the metabolic syndrome (MS) has the highest incidence rate. Limited by the requirements of insulin resistance evaluation, the definition proposed by WHO is somewhat unfeasible for practices. ATP definition may be replaced by IDF definition, because the populations defined by ATP definition is covered by the latter. Meanwhile, the abnormalities of fat mass distribution in the body ( i. e. , central obesity) , rather than its contents, may exacerbate the occurrence of MS, as well as the development of insulin resistance.
