Objective To explore the clinical value of Doppler tissue imaging (DTI) in evaluating abdominal aortic wall motion to predict pregnancy-induced hypertension (PIH).Methods The velocities of anterior abdominal aortic wall motion in 112 pregnant women with normal 20-40 weeks' pregnancy were detected by DTI and combined with simultaneous electrocardiography.Electromechanical time (EMT), left ventricular pre-ejection period (PEP), patients' height and weight were measured and recorded respectively.Pulsed wave time (PWT, PWT = EMT-PEP) and relative pulse wave velocity (RPWV) were calculated and analyzed.Medium and late stage PIH eases and time were recorded in clinical follow-up.Results PIH group were 11 cases, non-PIH group were 101 cases.E, S_1, S_2, D peak value in PIH group were significantly lower than those in non-PIH group [(2.02 ± 0.39 ) cm/s vs (2.32 ± 0.45 ) cm/s, (6.08 ± 0.87 ) cm/s vs(7.12 ±1.11 ) cm/s, (2.22 ± 0.65 ) cm/s vs( 2.83 ± 0.81 ) cm/s, (3.26 ± 0.54) cm/s vs( 3.86 ± 0.72 ) cm/s, P < 0.01]; EMT shortening[(120.87 ± 11.34) ms vs (134.32 ± 10.62) ms,P<0.05];PEP longer[(92.36±9.04) ms vs(83.11±8.95) ms,P< 0.05];PWT shortening[(31 ± 11) ms vs(45 ± 13) ms,P<0.01]; RPWV faster [( 1 02.28 ± 20.69) m/s vs (75.37 ± 18.74) m/s, P < 0.01].Conclusions Abdominal aortic wall motion has already changed in early stage of PIH.DTI is a valuable method to evaluate the abdominal aorta wall motion for early detection of PIH with high sensitivity, high accuracy and access to promote.

OBJECTIVETo study the effect of blood activating water relieving method (BAWRM) on heart functions and serum levels of NT-proBNP in patients with heart failure with normal ejection fraction (HFNEF).

METHODSSixty-four HFNEF patients were admitted to our hospital during January 2011 to June 2012. They were randomly assigned to the treatment group (32 cases) and the control group (32 cases). Patients in the control group received routine Western medical treatment, while those in the treatment group additionally took Chinese medical recipes for activating blood circulation and relieving water retention. Changes of Chinese medical syndromes, E/E', serum NT-proBNP contents were observed between the two groups.

RESULTSCompared with before treatment, their Chinese medical syndromes and E/E' were significantly improved, and serum NT-proBNP contents decreased in the two groups (P < 0.05). Compared with the control group, Chinese medical syndromes, E/E', serum NT-proBNP contents obviously decreased in the treatment group, showing statistical difference (P < 0.05).

CONCLUSIONBAWRM was an effective way to improve the diastolic function of HFNEF patients and lower the serum level of NT-proBNP with confirmative efficacy.

Objective To analyze the CT findings of tuberculous lymphadenitis in parotid gland, so as to improve the diagnostic accuracy of tuberculosis of parotid gland. Methods Nine cases with tuberculous lymphadenitis in parotid gland confirmed by surgical pathology and acid-fast bacilli after preoperative spiral CT plain scan and two phases dynamic enhancement scan were retrospectively analyzed.Imaging findings of CT were reviewed and compared with surgical pathology. Results Seven of the 9 cases of tuberculosis of the parotid gland occurred in the left side, and 2 in the right side, and superficial lobe involvement occurred in 8 cases and deep lobe in 1 ease. The lesion was classified as tumour type (8 cases)and infiltration type (1 case). In tumour type, the number of lesion was from 1 to 4, and the size was from 2.7 to 5.3 cm in diameter. One case of infiltration type measured 3.4 cm in diameter. On CT plain scan,the lesions showed homogeneous slight high-density with regular edge in 5 cases and irregular low-density in 4 cases, and 2 of them with partly blurred edge. On CT enhanced scan, uniform moderate enhancement was seen in 3 cases, circular enhancement in 4 cases, inhomogeneous enhancement in 1 case, and lace-like enhancement in 1 case. Local infiltration occurred in 6 cases. Lymphadenovarix in the same side of lesion occurred in 2 cases. Conclusion CT findings of tuberculous lymphadenitis in parotid gland present diversification, which correlate well with pathological changes. Understanding of characteristic CT findings of tuberculous lymphadenitis in parotid gland is helpful for differential diagnosis, but final diagnosis still depends on pathology and acid-fast baeilli.

Objective To investigate the correlation between intima-media thickness(IMT)and elasticity of carotid in patients with type 2 diabetes accompanied hyperlipidemia by quantitative intima-media thickness(QIMT)and quantitative arterial stiffness(QAS)technique.Methods Fifty-six patients with type 2 diabetes accompanied hyperlipidemia were involved into the study as case group.Forty-eight healthy volunteers were supplied as normal control group in the same period.IMT,compliance coefficient(CC),distensibility coefficient(DC)and stiffness index(β)of carotid were acquired through QIMT and QAS.Case group was divided into case group 1(IMT＜0.9mm)and case group 2(IMT≥0.9 mm),and analysis was performed furtherly.Results β,triglyceride(TG),lowdensity lipoprotein(LDL),cholesterol(Ch),glycosylated hemoglobin(GHb)and IMT had significant differences in case group 1,case group 2 and control group(P＜0.05),control group＜case group 1＜case group 2.DC and CC had significant differences in case group 1,case group 2 and control group(P＜0.05),control group＞case group 1＞case group 2.There was significant positive correlation between β and age,GHb,LDL and IMT of carotid respectively(r=0.811,r:0.764,r=0.732,r:0.729,respectively,P=0.000).Conchmions IMT of carotid could be measured accurately by QIMT.Structure imaging and functional imaging of carotid might be combined organically through QIMT and QAS.Depth study about early change of carotid in structure and function could be performed with these two techniques.

Objective To investigate the clinical value and the feasibility of strain-blood pressure index(SBPI) in assessing the elasticity of brachial artery and anterior tibial artery in patients with type 2 diabetes mellitus. Methods Forty-six type 2 diabetic patients and 50 healthy volunteers were involved. Maxmum of circumferential strain (CSmax) of brachial artery and anterior tibial artery were acquired through strain and strain rate imaging(Xstrain). Local systolic blood pressure(LSBP) and local diastolic blood pressure(LDBP) of brachial artery and anterior tibial artery were measured at the same time. SBPI,tibial-brachial index (TBI), and ankle-brachial index(ABI) were calculated, SBPI = CSmax/[(LSBP-LDBP) /LDBP]×100%,TBI = SBPI of anterior tibial artery/SBPI of brachial artery, ABI = LSBP of anterior tibial artery/LSBP of brachial artery. Parameters were compared between the case group and the control group. Results SBPI of anterior tibial artery and TBI had significant difference between the case group and the control group( P < 0.05), while SBPI of brachial and ABI had no significant difference( P >0. 05).Conclusions SBPI might be a new index for evaluating the elasticity of medium-sized arteries in patients with type 2 diabetes, and different changes caused by type 2 diabetes between brachial artery and anterior tibial artery could be reflected by TBI.

The aim of this Post-Marketing Surveillance study was to assess efficacy, safety and acceptance of acarbose treatment in Chinese type 2 diabetic patients under day-to-day practice conditions. A total of 2 480 patients were enrolled by 231 physicians throughout China into an open, prospective, uncontrolled, nonrandomised, multi-centre study. Main efficacy parameters were the changes in fasting and postprandial blood glucose concentrations as well as in HbA1c levels after acarbose treatment. The majority of patients had been previously treated with other oral anti-diabetic medication or insulin and received concomitant anti-diabetics during the mean observation period of 13.5 weeks. Most patients started on a daily acarbose dose of 50 mgt. i. d. Acarbose treatment reduced fasting blood glucose concentrations by 56. 1 mg/dl ( 18 mg/dl glucose = 1 mmol/Lglucose) and 2h-postprandial values by 111.3 mg/dl over the studyperiod. HbA1c decreased by 1.9％ and body weight by 0.9 kg. 76 acarbose-related adverse events occurred; two patients experienced serious adverse events.The attending physicians assessed treatment efficacy as "very good" or "good" for 90.1％ of the patients, tolerability for 89.1％ and acarbose acceptance for 87.1％ of the patients. Acarbose is efficacious, safe and well accepted by Chinese type 2 diabetic patients under day-to-day routine conditions, both as anti-diabetic mono therapy and in combination with other anti-diabetic drugs.

Objective To understand the situations of home establishments and the related domestic behaviors that causing injuries. Methods A total of 9760 families with regular residents in a community in Shanghai were investigated. Questionnaire was designed bascd on the Guidelines for Conducting Community Surveys on Injuries and Violence and International Classification of External Causes of Injuries. Results Inside the home settings, relative factors were found on issues as fire protection and using of electricity. In terms of household settings, 14.85% of the families had smoke alarm systems in the kitchen; 40.75% had no windows set for emergence. 50% to 70% of the residents had the idea of safe behaviors, including 35.93% of the families stored cleaning products,other chemicals or medical substances in alternative containers, such as used drinking bottle. Only 1.81% of the people being investigated thought that home was also a high risk place where injury might occur and it was placed number 9 in a multiple choice questionnaire. Data from the multiple level model analysis showed that factors as number of family members, space, education, profession etc. were closely related to the situation of home settings and their resident's behaviors. Conclusion Many injury related factors were found related to home establishments and people' s daily behaviors at home which called for interventions to be taken.
