Objective To evaluate early changes of femoral artery elasticity in type 2 diabetes mellitus (T2DM) combined with microalbuminuria (MA) patients using ultrasound radio-frequency technology,and to study the clinical significance.Methods 51 T2DM without MA patients were enrolled in Group A,and 53 T2DM with MA patients were enrolled in Group B.In order to observe the early elastic changes in the subjects,two-dimensional ultrasound was used to eliminate patients whose intima-media thickness (IMT) was ＞1 mm.The femoral arteries were imaged by two-dimensional ultrasonography,and then the IMT,femoral artery inner diameter (D),distensibility coefficient (DC),compliance coefficient (CC),elasticity coefficient (α and β),and pulse wave velocity (PWV) were real-time tested using quality intima-media thickness (QIMT) and quality arterial stiffness (QAS) analyzing systems.Besides,the differences and correlation analyses of these parameters between the two groups were conducted.In addition,some other parameters of sujects in both group A and B were also determined and analysed,including total cholesterol (TC),triglyceride (TG),low-density lipoprotein cholesterol (LDL-C),high-density lipoprotein cholesterol (HDL-C),creatinine (CREA),glycosylated hemoglobin (HbA1c),fasting blood glucose (FPG),2h postprandial plasma glucose (2hPG) and body mass index (BMI).Results There were no significant differences in the elastic parameters of femoral arteries between the male and female subjects (P＞0.05),and between left and right sides (P＞0.05) within a same group.Compared with group A,group B had lower CC and DC (P＜0.05) and higher α,β and PWV (P＜0.05).Pearsons correlation analysis indicateal that,CC was negatively correlated with α,β and PWV (P＜0.05),and DC was also negatively correlated with α,β and PWV (P＜0.05).There was no significant difference in the inner diameters of femoral arteries between the two groups (P＞0.05).The levels of TG,HbA1c,FPG and 2hPG in group B were significantly higher than those in group A (P＜0.05).There were no significant differences in TC,HDL-C,LDL-C,CREA and BMI between the two groups (P＞0.05).Conclusions The decrease of arterial elastic function is earlier than morphological changes,that is,it may have occurred before MA in T2DM patients.The application of ultrasound radio-frequency analyzing technology has certain significance in the clinical early diagnosis and treatment.

BACKGROUND: Peri-intraventricular hemorrhage (PIVH) in preterm infants is one of the most important reasons for mortality and disability. Moreover, investigative exponents may bring supported data for incidence rate of PIVH and high-risk factors of preterm infants with PIVH.OBJECTIVE: To explore the incidence rate and analyze the high-risk factors of PIVH in preterm infants.DESIGN: Survey and analysis.SETTING: Tongji Hospital of Tongji Medical College, Huazhong University of Science and Technology; Beijing Obstetrics & Gynecology Hospital, Capital Medical Universit; Qinhuangdao Maternity and Infants' Hospital of Hebei Province.PARTICIPANTS: A total of 1 122 preterm infants of 26.3-36.8 gestational age were selected from Beijing Obstetrics & Gynecology Hospital, Qinhuangdao Maternity and Infants' Hospital from January 2002 to August 2005. All infants received ultrasonic examination on skull within 1 week. There were 594 boys and 528 girls, and the birth weight was 850-4 500 g.METHODS: All infants received ultrasonic examination on skull within 1 week. New Philips 5500 and GE Healthcare Logiq 400 ultrasonic diagnosis devices were provided by Philip Company, Dutch and GE Company, respectively.MAIN OUTCOME MEASURES: The incidence rate and related high-risk factors of PIVH.RESULTS: All 1 122 preterm infants were involved in the final analysis. Among 1 122 preterm infants, 619 cases (55.2%) had PIVH; especially, 110 had severe PIVH with the degree more than Ⅲ, which was accounted for 17.8%.High-risk factors were mainly low gestational age, low birth weight, mechanical ventilation, hypoglycemia, hypercapnia,hyperlactic acidemia, acidosis, hypoxia, abnormal blood coagulation, and so on. Antenatal corticosteroid could reduce the incidence rate of PIVH. However, there was no obvious effect on preterm infants of old gestational age.CONCLUSION: Routine intracranial ultrasonic examination is useful for the diagnosis of PIVH in preterm infants.

Objective To screen gastric infiltrating carcinoma from gastric high grade intraepithelial neoplasia (HGIEN) checked again by regular gastroscopy and confocal laser endomicroscopy(CLE).Methods From January 2005 to December 2010,82 patients with endoscopic biopsy and the tissue pathological diagnosed HGIEN were collected at Department of Gastroenterology,Ruijin Hospital,Jiaotong University.61 male patients and 21 female patients were collected,of which 38 patients underwent common gastroendoscopy and the other 44 patients were underwent CLE besides common gastroendoscopy.The pathological diagnosis of endoscopic biopsy tissues were compared,and patients with indications were referred to surgery and pathological examination again.Results A total of 82 patients were confirmed by repeated examination,and there were 8 cases of inflammation or benign ulcers (24.4％),12 cases of low grade intraepithelial neoplasia (14.6％),10 cases of HGIEN (12.2％),52 cases of infiltrating carcinoma (63.4％).36 cases of differentiated carcinoma and 16 cases of undifferentiated carcinoma.Of the 21 infiltrating carcinoma cases diagnosed by CLE,17 cases (81.0％) were consistent with the pathological diagnosis.The consistent parameter value of κ between CLE diagnosis and pathological diagnosis was 0.7250.Conclusion It is necessary to make differential diagnosis of infiltrating cancer in patients with endoscopic biopsy and the tissue pathological diagnosed HGIEN.

Objective To explore the effects of insulation measures on blood coagulation during laparotomy in the aged patients. Methods Sixty patients were randomly divided into the experimental group and the control group with 30 cases in each group from September 2007 to August 2008. The experimental group received a series of insulation measures based on general perioperative nursing care, which was given to the control group. Patients' temperature, platelet count (PLT), prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TV),fibrinogen (Fbg) were measured and these preand postoperative values together with blood loss during operation were compared between two groups. Results No significant change was seen in perioperative body temperature in the experimental group, the incidence rate of hypothermia was lower, the change in coagulation index was better than that of the control group. Conclusions These results suggested that mild hypothermia could influence aged patients' blood coagulation function and increase blood loss during laparotomy. Active insulation measures can maintain the stability of patients" temperature.
