OBJECTIVETo evaluate the efficacy of Breviscapine on essential hypertension (EH) patients complicated with micro-albuminuria of renal impairment.

METHODSSeventy-six EH patients were randomly assigned to the control group and the treated group, the former was given amlodipine, captopril/uropidil and the latter was given in addition Breviscapine intravenously dripped for 2 treatment courses. The indexes of serum creatinine (Cr), blood urea nitrogen (BUN), blood and urinary beta(2)-microglobulin (beta(2)-MG), and quantitative determination of 24 hrs urinary protein were evaluated before and after treatment.

RESULTSIn the control group, compared with before treatment, the quantitative determination of 24 hrs urinary protein got reduced significantly (P < 0.05), while in the treated group, both urinary beta(2)-MG and quantitative determination of 24 hrs urinary protein got lowered significantly (P < 0.05 and P < 0.01). But after treatment, compared with the control group, urinary beta(2)-MG and quantitative determination of 24 hrs urinary protein in the treated group were obviously reduced (P < 0.05).

CONCLUSIONBesides lowering blood pressure effectively, Breviscapine could improve the renal function significantly and reduce the urinary micro-albuminuria, hence showing promising effect on renal protection.

INTRODUCTIONFirst trimester screening (FTS) is a validated screening tool that has been shown to achieve detection rates of 84%-90% for trisomies 21, 18 and 13. However, its effectiveness for different maternal ages has not been assessed. The present study aimed to assess the performance of FTS in an Asian population, and to compare its effectiveness in older (≥ 35 years) and younger (< 35 years) women. The potential use of noninvasive prenatal test (NIPT) as a contingent screening test is also examined.

METHODSData on cases of FTS performed on singleton pregnancies over a six-year period was collated from two Singapore maternal centres, National University Hospital and Singapore General Hospital. Cases that had a 1:250 risk of trisomy were considered to be screen-positive. Pregnancy outcomes were obtained from birth records or karyotype test results.

RESULTSFrom 10,289 FTS cases, we obtained a sensitivity of 87.8%, a specificity of 97.6%, a false positive rate of 2.4% and a false negative rate of 0.06% for the detection of aneuploidy. The overall detection rate for trisomy 21 was 86.5%-85.7% for older women and 87.5% for younger women. The mean number of invasive tests required per case of trisomy 21 was 9.3 in younger women, 8.6 in older women and 13.5 in women with intermediate risk (1:250-1,000).

CONCLUSIONWhile the performance of FTS was similar in younger and older women, more invasive procedures were required to diagnose trisomy 21 in women with intermediate risk. It may be advantageous to offer contingent NIPT to this group of women to reduce the risk of iatrogenic fetal loss.

BACKGROUND: Over the last 10-20 years, international guidelines and consensus statements for the management of common allergic diseases (e.g. allergic rhinitis and asthma) have been developed and disseminated worldwide. However, their impact on knowledge and standard of clinical practice among primary care physicians and specialists is unknown. OBJECTIVE: To investigate need for an improvement in the dissemination of international guidelines for the diagnosis and management of allergic rhinitis. METHODS: Seven medical students who attended 3-day 1st International Basic Allergy Course (2010) took down all questions raised during the entire course. A systemic analysis of these questions was performed to identify areas for improvement in diagnosis and management of allergic diseases mainly in the Association of Southeast Asian Nations (ASEAN) region. RESULTS: 268 participants, 143 males and 125 females, comprising Ear, Nose and Throat (ENT) specialists (n = 106) and trainees (n = 34), general practitioners (n = 87), and other healthcare professionals (n = 41) attended the course. Of the 103 questions recorded, 59 were regarding treatment modalities in allergy practice such as immunotherapy (n = 38), pharmacologics (n = 15), nasal surgery (n = 2), and others (n = 4). 41 questions (39.8%) have answers based in the Allergic Rhinitis and its Impact on Asthma guidelines (2001 and 2008). Certain questions were selected for further analysis because they appeared to be (a) more commonly asked (e.g. immunotherapy) or (b) were deemed to be challenging or, even controversial (e.g. food allergy and differential diagnosis between vasovagal and anaphylaxis reaction), as the recommendations in current international guidelines were less well-defined. CONCLUSION: Our study identified several problems that, if tackled, could help minimize confusion and provide better care for patients suffering from allergic diseases especially in the ASEAN region.

Objective To study the protective effect of trimetazidine pretreatment on myocardial I/R in a rat I/R model and its mechanism.Methods One hundred and twenty SD rats were divided into control group,I/R group,HSP70 inhibitor group,trimetazidine treatment group and combined treatment group (24 in each group).The rats in each group were further divided into 30 min reperfusion group,4 h reperfusion group and 8 h reperfusion group (8 in each group).Their HSP70-positive myocardial cells were calculated,their serum CK,CK-MB,MDA,SOD levels and their myocardial infarction size were measured.Results The serum CK and CK-MB levels were significantly higher in I/R group,HSP70 inhibitor group,trimetazidine treatment group and combined treatment group than in control group and were significantly lower in trimetazidine treatment group than in combined treatment group and I/R group after reperfusion for 4 and 8 h (P＜0.01).The serum levels of HSP70 and SOD were significantly higher,the MDA levels were significantly lower in trimetazidine treatment group than in combined treatment group and I/R group after reperfusion for 30 min,4 and 8 h (P＜0.01).The infraction size was significantly smaller in trimetazidine treatment group than in combined treatment group and I/R group after reperfusion for 4 and 8 h (P＜0.05).Conclusion Trimetazidine can increase the serum HSP70 level in myocardial cells,reduce the infarction size,and protect the myocardium against I/R in rats.
