Objective To investigate the relationship of glycaemia level and the artery stiffness by means of ultrasonography. Methods Among the individuals selected for screening for impaired glucose tolerance, the systolic and diastolic diameters of both common carotid arteries in a single cardiac cycle, and the intima-media thickness were measured. Based on these measured parameters the artery compliance (AC), stiffness index and Yang's elastic Model (YEM) were calculated. Both fasting blood sugar level and that of 2 hours after 75g glucose challenge were quintiled so as to compare the arteriosclerosis surrogates. Linear correlation and partial linear regression were used to analyze the relationship of both fasting and post-challenge blood sugar levels with the three surrogates. Finally, those surrogates were also compared among different glucose tolerance categories. Normal glucose tolerance (NGT, n=97), impaired glucose tolerance (IGT, n=51) and type 2 diabetes mellitus (T2DM, n=73) were classified by the previous results of 75g oral glucose tolerance test. Results The AC decreased, and SI and YEM elevated significantly after the third quintile of fasting glycaemia, while the similar changes were found after the fourth quintile of 2 hour glycaemia. Both fasting and post-challenge glycaemia correlated inversely with AC and positively with SI and YEM. Partial correlation analysis showed that the significance of the correlation of fasting glucose with the arteriosclerosis surrogates disappeared but that of post-challenge glucose with those surrogates remained. In different categories of glucose tolerance, AC decreased but YEM rose significantly in IGT and T2DM when compared with NGT. The SI of T2DM was higher than of NGT. However the three surrogates remained similar between IGT and T2DM. Conclusions Artery stiffness was enhanced with the increase in fasting or post-challenge glycaemic levels. Post-challenge glycaemia was a better determinant than fasting glycaemia. The degree of arteriosclerosis in IGT was higher than that in NGT, but was similar to that of T2DM.

221 subjects at risk for MS were enrolled and evaluated.The discovered mean number of MS components was little greater by IDF definition than by CDS one(2.33 vs 2.09,P>0.05).The concordance rate of both definitions was 80% in diagnosing MS.The female MS prevalence was higher by IDF (18/83) than by CDS (2/83)(P<0.05).But male MS prevalence was higher by CDS (18/138) than by IDF (7/138) (P<0.05).In those with normal glycaemia, more individuals were diagnosed to have MS by IDF definition (21/94,22.3%) than by CDS one (10/97,10.3%)(P<0.05).Of people with MS diagnosed on CDS definition, 11 (12%) were non-obese.Finally, 6% MS people was missed by IDF definition due to neglecting postprandial-challenge glycemia.In conclusions, the two definitions are comparable in identifying MS and its components, while from CDS to IDF definition some MS people drift in the way as follows: from men to women, from dysglycemia to abnormal fat metabolism, and from non-obesity to obesity.

The study of subjcts with T2DM (n=120) and NGT (n=106) in using the screening of PGC-1? gene for SNPs by PCR-SSCP and DNA sequencing showed that four SNPs(Thr394Thr、Gly482Ser、Thr528Thr、Thr612Met) in the PGC-1? gene were found in 50 Han Chinese type 2 diabetic patients.A Gly482Ser polymorphism of PGC-1? gene was associated with type 2 diabetes.[

Abstract Hypertensive disorders of pregnancy (HDP) are a common severe complication during pregnancy, which is characterized by complex etiology, unclear pathogenesis and lack of effective tools for early diagnosis and prediction. Recently, the development of omics technology provides new insights into the research into HDP. Based on national and international publications from 2011 to 2022, this review summarizes the application of genomics, proteomics, metabolomics, and microbiomics in the pathogenesis and prediction of HDP, so as to provide insights into the prediction, prevention and precise treatment of HDP.

Objective To observe the relationship between early lactate clearance and APACHEⅡ in critically ill patients. Methods In 121 critically ill patients,APACHE Ⅱ and lactate clearance rate were recorded. According to APACHE Ⅱ score,all patients were divided into≤10 score group, (11 ～20) score group,(21 ～30) score group and ＞ 30 score group, then compared the level of the early lactate clearance rate. The early lactate clearance rate were also compared between survival group and death group. Then the relationship between early lactate clearance and APACHE Ⅱ were analyzed. Results In( 11 ～20) score group,the early lactate clearance rate was lower than those in ≤ 10 score group, but the difference was not significant ( P ＞ 0. 05 ). The early lactate clearance rate in (21 ～ 30) score group ( 18. 35 ± 10. 01 ) % was lower than those in ( 11 ～ 20) score group (27.35 ± 10. 22) % ( t = 3.481, P ＜ 0. 01 ),in ＞ 30 score group( 11.98 ± 9. 93 )% those was lower compared with (21 ～30) score group( t = 2. 968, P ＜ 0. 01 ). In death group, APACHE Ⅱ score(28. 1 ± 6. 7 ) was higher than that in survival group ( 18. 8 ± 8. 4) ( t = 3. 030, P ＜0. 01 ), the early lactate clearance rate was lower ( t = 3. 619, P ＜ 0. 01 ). APACHE Ⅱ score correlated well with the mean level of the early lactate clearance rate ( r = - 0. 641, P ＜ 0. 01 ). Conclusion The lactate clearance rate was the good fator on evaluation of condition and prognosis in the critically ill patients.

Objective To observe the efficacy and adverse effects of conventionally fractionated (CF) versus hypofractionated (HF) three-dimensional conformal radiotherapy (3DCRT) for hepatocellular carcinoma (HCC) with portal vein tumor thrombosis.Methods A retrospective analysis was performed on the clinical data of 65 patients with HCC suitable for 3DCRT from 2008 to 2012.These patients were randomly divided into HF group (n =32) and CF group (n =32).The HF group received 3DCRT at a total dose of 45-55 Gy (3-4 Gy/fraction,3-5 fractions/week),while the CF group at a total dose of 40-56 Gy (2 Gy/fraction,5 fractions/week).Results The follow-up rate was 100％.For the HF group and CF group,the short-term response rates were 72％ vs.55％ (P =0.034),the 1-year local control rates were 72％ vs.55％ (P=0.034),the 1-year overall survival rates were 59％ vs.45％ (P=0.042),and the numbers of individuals with grade 1-2 acute gastrointestinal reactions,deterioration of liver function,and radiation hepatitis were 14 vs.11,8 vs.8,and 1 vs.0,respectively (P =0.237).Conclusions HF 3DCRT is superior to CF 3DCRT in the treatment of HCC.

Objective To study the clinical features of the ectopic ACTH syndrome in order to increase the early diagnostic rate. Methods Clinical features and imaging diagnosis of 8 consecutive patients with ectopic ACTH syndrome were described and laboratory data were compared with those of 16 consecutive patients with ACTH-dependent Cushing′s syndrome accompanied with hypokalemia. Results The ectopic ACTH syndrome occurred in 11.3% of all patients with Cushing′s syndrome and the common causes were lung cancer and bronchial carcinoid. The clinical features of the ectopic ACTH syndrome differ from those of ACTH-dependent Cushing′s syndrome. Ectopic ACTH syndrome occured predominently in men and showed the duration of symptoms less than 5 months and a more rapid clinical course. There were apparent muscle weakness, edema of lower extremities, higher plasma ACTH and free cortisol (F), severe metabolic alkalosis and more negative responses to the high dose of dexamethasone suppression test. Chest X-rays and CT were helpful for tumor localization. The prognosis depended on whether the tumor was malignant or benign, and complete surgical resection of tumor was the key treatment. Conclusion Ectopic ACTH syndrome could be distinguished from the ACTH-dependent Cushing′s syndrome with hypokalemia according to the clinical features, laboratory data, plasm ACTH and F levels, as well as chest X-rays and CT.

Objective:To analyze the dental and mandibular asymmetry of adults with Class Ⅱ subdivision malocclusion.Methods:The jaw bones of 30 adults with Class Ⅱ subdivision malocclusion(case group)and 30 with normal-occlusion(control group)were scanned by CBCT.Linear and angular comparison was conducted between the two groups.Results:Dental midline deviation was ob-served in case group,mostly in mandibular arch (60%).The development of Class Ⅱ molar relationship correlated mainly to distally positioned mandibular molar on Class Ⅱ side.Conclusion:In the adults with Class Ⅱ subdvision malocclusion odontogenic asymme-try is the major factor,bony asymmetry is the miner.
