Objective: To explore the relationship between lower extremity atherosclerosis disease (LEAD) and cardiovascular risk factors in elder people.
Methods: A total of 700 consecutive patients receive lower extremity Color Doppler ultrasound in our hospital from 2013-05 to 2014-11 were investigated. The patients were divided into 3 age groups: Young and middle group, n=83, Elder group, n=377 and Senile group, n=240. Based on ultrasound scoring system, the patients were divided into 4 groups: Normal group, n=112, Mild atherosclerosis (Mild) group, n=81, Moderate group, n=466 and Severe group, n=41. The cardiovascular risk factors among different groups were compared.
Results: Multivariate unconditional logistic regression analysis showed that age, smoking, history of diabetes, uric acid (UA), ankle-brachial index (ABI) were the independent risk factors for LEAD (B=0.144, 1.496, 0.963, 0.004, -2.510; 95% CI: 1.120-1.190, 2.257-8.824, 1.456-4.716, 1.001-1.007, 0.012-0.534;P=0.000, 0.000, 0.001, 0.006, 0.009 respectively. Ordinal logistic regression analysis indicated that age, male gender, smoking, ABI, UA, history of hypertension were related to the severity of atherosclerosis (B=0.130, 0.737, 0.592, -3.365, 0.003, 0.735; 95% CI: 0.097-0.162, 0.222-1.252, 0.052-1.132, -4.674 to -2.055, 0.001-0.005, 0.313-1.157;P=0.000, 0.005, 0.032, 0.000, 0.005, 0.001 respectively. Compared with Young and Middle groups, Elder and Senile groups had increased rates of moderate and severe arteriosclerotic lesions; compared with Elder group, Senile group presented the higher incidence of moderate and severe lesions, allP<0.01. With elevated age, the severity score of LEAD increased accordingly,P<0.01.
Conclusion: Lower extremity atherosclerosis lesions were more severe in elder patient, and it was particularly severe in senile patients.

Objective To assess the clinical value of serum uric acid levels in patients with acute ST-elevation myocardial infarction(STEMI).Methods A total of 502 consecutive patients with STEMI were enrolled from January 2005 to December 2010 for retrospective study.The level of serum lipid,echocardiographic data and in-hospital major adverse cardiovascular events(MACE)in patients with hyperuricemia(n =119)were compared with those in patients without hyperuricemia(n =383).The relationship between the level of serum uric acid and the degree of diseased coronary artery was analyzed.All data were analyzed with SPSS version 17.0 software to make t test and x2 test and Pearson correlation analysis.Results Serum uric acid level was positively correlated with serum triglyceride level.Compared with non-hyperuricemia patients,hyperlipidemia was more commonly found among hyperuricemia patients (43.7％ vs.33.7％,P =0.047),and serum triglyceride level was significantly higher in hyperuricemia patients[(2.11 ± 1.24)mmol/L vs.(1.78 ± 1.38)mmol/L,P =0.014].But a significant association between serum uric acid level and one or more diseased vessels was not observed(P ≥ 0.05).Leftventricular end-diastolic diameter(LVEDd)was found to be larger in hyperuricemia patients than non-hyperuricemia patients[(53.52 ±6.19)mm vs.(52.18 ±4.89)mm,P =0.041].Higher incidence in left systolic dysfunction and diastolic dysfunction was discovered in hyperuricemia patients(36.4％ vs.15.1％,P ＜0.01; 68.2％ vs.55.8％,P =0.023).Also,hyp-eruricemia patients had more in-hospital MACE(P ＜ 0.05).Conclusions Serum uric acid level is positively correlated with serum triglyceride level,but not with the severity of coronary artery disease.Hyperuricemia patients after STEMI tended to have higher incidence in left systolic dysfunction and diastolic dysfunction,and have more in-hospital MACE.

Objective To investigate the change of serum ghrelin and sex hormones levels in girls with precocious puberty . Methods 87 girls with precocious puberty were divided into the simple premature thelarche (SPT ) and central precocious puberty (CPP) groups according to the results of gonadotropin releasing hormone(GnRH) stimulation test ,size of ovary and uterus ,and de-velopmental status of the secondary sex characteristics ,with 34 age-matched healthy girls as control group .The serum ghrelin level was quantitatively measured by enzyme-linked immunosorbent assay (ELISA) ,luteinizing hormone(LH) ,follicle stimulating hor-mone(FSH) ,estradiol(E2) ,progesterone(PRGE) ,prolactin (PRL) ,testosterone (TSTO) and LH and FSH stimulated by GnRH after 30 ,60 ,90 min were measured by chemoluminescence technique .Results The ghrelin level in the CPP group was significantly higher than that in the control group(P<0 .05);there was no statistically significant difference between the SPT group and the control group and between the CPP group and the SPT group (P>0 .05) .The 5 indexes of sex hormone (LH ,FSH ,E2 ,PRL , PRGE) in the CPP group were significantly higher than those in the SPT group and the control group (P<0 .05) ,but no statisti-cally significant difference existed between the SPT group and the control group (P>0 .05);the TSTO level had no statistically sig-nificant difference among 3 groups(P>0 .05) .Conclusion The serum levels of ghrelin and 5 indexes of sex hormone (LH ,FSH , E2 ,PRL ,PRGE) in girls with CPP are significantly increased .

Objective To explore the effect of reconstructing unilateral cleft lip by changing the arc-shaped incision, combined with the 3D reconstruction of upper lip muscles.Methods Twenty unilateral cleft lip patients were treated by using a new surgical operation, the 3D reconstruction of upper lip muscle, to restore normal anatomy and stress of the mucous membrane, muscle and skin.Operation scar was designed for straight line, located on the philtral ridges of the contour line;phitrum and philtral ridges were rebuilt, and postoperative scar reduced.Results A lot of 20 patients had no local infection, hemorrhage, complex crack, and were stage I incision healing.Followed up for 1-8 months postoperatively, the patient's lip bow line continuity was good, with symmetrical shape and good phitrum and philtral ridges;scar was hidden on the philtral ridges of the contour line, and no obvious upper lip scar contracture found through the follow-up period.Conclusions This improved method is simple in the incision design, and less scar hidden on the philtral ridges of the contour line after operation, which can maximize the recovery of the appearance of nose and upper lip with satisfactory effect.It is a feasible improvement method of repairing unilateral cleft lip.

The noninvasive measurement of liver stiffness (LS) was evaluated by transient elastography (FibroScan) and the possible influencing factors from the patients' clinical situations including age, gender, liver inflammation represented by alanine transaminase (ALT) and total billirubin (TBIL) level, HBV replication (HBV DNA loads), portal vein pressure (portal vessel diameter, PVD), splenic thickness (SPT) and body mass index (BMI) were analyzed in patients with chronic hepatitis B (CHB). A total of 466 patients including 31 patients with acute-on-chronic liver failure (ACLF), and 435 patients with chronic hepatitis B (CHB) among which 82 patients were diagnosed with liver cirrhosis (LC) by clinical manifestations and liver B-type ultrasonic inspection were enrolled at Tongji Hospital from April to December 2009. LS was measured by a FibroScan device (EchoSens, France). Simultaneously, ALT and TBIL levels, HBV DNA loads, PVD, SPT and BMI in all patients were also tested. Forty-one healthy volunteers served as controls. The values of LS were correlated positively with ages of CHB patients and significantly higher in males than in females. In patients with BMI>28 kg/m(2) (obesity) and abnormal levels of ALT and TBIL, LS values were significantly increased as compared with those having normal levels of ALT and TBIL. The patients with ACLF had the highest LS value. Furthermore, LS values in the patients with LC were significantly higher than those in patients without LC. It is concluded that noninvasive measurement of liver fibrosis by FibroScan provides an alternative method to evaluate liver fibrosis of patients with CHB. In order to properly illustrate the stiffness value taken by transient elastography, patients' gender should be taken into consideration and it is also suggested to avoid possible influencing factors including liver inflammation (high levels of ALT and TBIL) and obesity (high BMI).
