To systematically evaluate the efficacy and safety of tripterygium glycosides (TG) combined with ACEI/ARB preparation in treating diabetic nephropathy stage IV. The computer retrievals were made in Cochrane Libarary, PubMed, Embase, SCI, Sinnomed, CNKI, Chinainfo and VIP, and hand retrievals were conducted for meeting and academic papers (updated to December 30, 2014), in order to collect randomized controlled trials and quasi-randomized control trials for TG combined with ACEI/ARB preparation in treating diabetic nephropathy stage IV and set the literature inclusion and elimination standards. Eligible literatures were included and evaluated according to standards in Cochrane Handbook. RevMan 5.3 and Stata 12.0 were used for a Meta-analysis. A total of 13 randomized controlled trials and quasi-randomized control trials involving 1119 patients with diabetic nephropathy were included. The Meta analysis result showed that compared with the control group, the combination group showed better effects in reducing the 24-hour urinary protein [MD = -0.84, 95% CI (-1.02, -0.66)], raising albumin [SMD = 0.98, 95% CI (0.81, 1.16)], the total efficiency [OR = 4.23, 95% CI (2.77, 6.46)] and the significant efficiency [OR = 5.35, 95% CI (2.70, 10.60)], with no statistical difference in Serum Creatinine between Both groups [MD = -0.82, 95% CI (-4.30, 2.66), P = 0.64]. However, the risk of adverse reactions increased by 7% [RD = 0.07, 95% CI (0.03, 0.12)]. The Egger's test showed no publication bias. Tripterygium Glycosides combined with ACEI/ARB in treating diabetic nephropathy stage IV is supper than the single administration of ACEI/ARB, with a good prospect in clinical application. Nevertheless, due to the small-size and low-quality samples in this study, more high-quality and large sample-size randomized controlled trials shall be conducted to verify the findings.

2.What is the optimal initiation timing of angiotensin converting enzyme inhibitor treatment for maximum benefits in acute myocardial infarction patients?
Hong-Bing YAN ; Shao-Ping WANG
Chinese Medical Journal 2011;124(3):464-466
Randomized clinical trials led to the clinical recommendation that angiotensin-converting enzyme inhibitors (ACEI) should be used as standard therapy in most patients experiencing an acute myocardial infarction (AMI). However, the optimal initiation timing of treatment, as well as the exact mechanisms, have not been completely resolved, especially with the development of reperfusion strategy after AMI. Earlier initiation of ACEI might be associated with more prompt recovery of left ventricular ejection fraction due to more rapid attenuation of negative remodeling.

OBJECTIVE:
To determine the relation between plasma tissue factor (TF) and serum angiotensin II(AngII) and the effect of different dosages of fosinopril on chronic heart failure(CHF).
METHODS:
Thirty healthy controls and 35 CHF patients were recruited to observe AngII,TF, left ventricular ejection fractions(LVEF) and left ventricular end-systolic volume index (LVESVI) at baseline and 10 weeks after the treatment. The 35 patients were randomly assigned into 2 groups: A routine dosage fosinopril group received 10 mg once daily and a middle dosage group received 10 mg twice a day for 10 weeks.
RESULTS:
Compared with the healthy controls, AngII,TF,and LVESVI significantly increased (P<0.01) and LVEF significantly decreased (P<0.01) in CHF patients. The TF was positively correlated with AngII(r=0.2491, P<0.01) in the patients. After the 10-week treatment with different dosages of fosinopril, AngII,TF,and LVESVI obviously decreased(P<0.05 or P<0.01) and LVEF significantly increased in the 2 groups (P<0.05 or P<0.01). The middle dosage group changed more than the routine dosage group (P<0.01).
CONCLUSION
TF is positively correlated with AngII in CHF patients. Fosinopril can greatly improve cardiac function and antagonize prethrobotic state,and the therapeutic effect improves with the dosage increase.

4 liters of polyethylene glycol (PEG) solution is commonly used to evacuate the colon before colonoscopy. This substance, however, is known to cause electrolyte abnormalities such as hyponatremia. Seizures caused by hyponatremia associated with bowel preparation have only rarely been reported. We report the case that a 75-year-old woman with no prior history of seizures was developed severe hyponatremia (112 mEq/L) with generalized tonic-clonic seizure and mental change after ingestion of 4L of PEG solution. Past medical history was notable for thiazide diuretics. Her symptoms are improved during intravenous administration of hypertonic saline for the correction of hyponatremia. Patients with impaired ability to excrete free water those with renal insufficiency, hypothyroidism, mineralocorticoid deficiency, liver cirrhosis, or heart failure as well as those taking drugs which including thiazide diuretics, NASIDs, and ACE inhibitors have risk of hyponatremia following bowel preparation for colonoscopy. We conclude that physicians should check patient's condition and electrolyte abnormalities before colonoscopy procedures.

OBJECTIVETo compare the effects of high, middle and low doses of enalapril in preventing left ventricular remodeling (LVRM) after acute myocardial infarction (AMI) in rats, especially evaluating the efficacy of low dose enalapril.
METHODSAMI was induced by ligating the left coronary artery in 149 female SD rats. 48 hours after the procedure, the 97 surviving rats were randomized to one of the following four groups: (1) AMI controls (n = 24), (2) high-dose (10 mg x kg(-1) x d(-1), n = 25), (3) middle-dose (1 mg x kg(-1) x d(-1), n = 23), and (4) low-dose (0.1 mg x kg(-1) x d(-1), n = 25) enalapril groups. In addition, sham-operated (n = 13) and normal rats (n = 10) were randomly selected to serve as non-infarction controls. Enalapril was delivered by direct gastric gavage. After 4 weeks of therapy, hemodynamic studies were performed, then the rat hearts were fixed with 10% formalin and pathology analysis was performed. Exclusive of the dead rats and those with MI size < 35% or > 55%, complete experimental data were obtained from 67 rats, which were comprised of (1) AMI controls (n = 13), (2) high-dose enalapril (n = 13), (3) middle-dose enalapril (n = 12), (4) low-dose enalapril (n = 12), (5) sham-operated (n = 8) and (6) normal (n = 9) groups.
RESULTSThere were no significant differences among the four AMI groups in infarction size (all P > 0.05). Compared with the sham-operated group, the left ventricular (LV) end diastolic pressure (LVEDP), volume (LVV), absolute and relative weight (LVAW, LVRW) in AMI group were all significantly increased (all P < 0.001), while maximum LV pressure rising and dropping rates (+/- dp/dt) and their corrected values by LV systolic pressure (+/- dp/dt/LVSP) were all significantly reduced in the AMI control group (P < 0.01 - 0.001), indicating LVRM occurred and LV systolic and diastolic functions were impaired. Compared with the AMI group, LVEDP, LVV, LVAW and LVRW were all significantly decreased in the three enalapril groups (control P < 0.001), with the reduction of LVEDP, LVV and LVAW being more significant in high-dose than in low-dose enalapril groups (all P < 0.05), and the +/- dp/dt/LVSP were significantly increased only in the high and middle-dose enalapril groups (P < 0.01).
CONCLUSIONSHigh, middle and low doses of enalapril were all effective in preventing LVRM after AMI in the rat, with low dose enalapril being effective and high dose superior. As for LV functional improvement, only high and middle-dose enalapril were effective.

One hundred and sixteen senile patients (older than 65 years) with chronic heart failure (CHF) were analyzed retrospectively in order to verify if old patients with CHF would benefit from long-term (one year) angiotension-converting enzyme inhibitor (ACEI) treatment. The frequency of drugs (including ACEI, digitalis and diuretic) used was stratified into four degrees accordingly. Development of the CHF was scored with regard to relapse rate and severity of this disease. Stepwise regression analysis was applied to explore the relationship between the scored outcome of CHF and the frequency of individual drug administration. A significant relationship of the scored outcome of CHF to the frequency of ACEI usage but not to digitalis nor to diuretics was found (partial coefficient of the correlation r = 0.42, P = 0.002). It was concluded that the long-term administration of ACEI improves the outcome of CHF in senile patients.

Singapore medical journal 2014;55(3):146-149
INTRODUCTIONThe incidence of cough induced by angiotensin-converting enzyme (ACE) inhibitors has been reported to be 5%-20%, with less than half of affected patients requiring discontinuation due to persistent cough. However, the incidence in the local Asian population has not been studied. This study aimed to objectively evaluate the incidence of discontinuation of ACE inhibitors due to cough, in a primary healthcare centre in Singapore.
METHODSWe retrospectively reviewed the medical records, both electronic and written, of patients who attended Tampines Polyclinic to identify those who were newly prescribed ACE inhibitors. The written medical records were analysed to identify patients who discontinued the use of ACE inhibitors and to find out the reasons for discontinuation.
RESULTSA total of 424 patients were identified during the study period. Out of the 424 patients, 129 (30.4%) discontinued the use of ACE inhibitors due to cough. Overall, 90 (21.2%) patients who were initially started on ACE inhibitors were eventually switched to angiotensin receptor blockers (ARBs).
CONCLUSIONIn our cohort, the incidence of discontinuation of ACE inhibitors due to cough is higher than most other studies. The relationship between ethnicity and tolerance of medications should not be underestimated. As there is a high incidence of discontinuation of ACE inhibitors due to cough in the local population, ARBs may be a reasonable substitute as a first-line medication, if clinically indicated.

To evaluate the effects of cyclosporin A (CyA) on clinical outcome and pathologic changes in children with IgA nephropathy (IgAN), we retrospectively evaluated 14 children (mean age 8.9+/-2.9 yr; eight males, six females) who were treated with CyA and steroids. The starting dose of CyA was 5 mg/kg per day, and the drug level was maintained at 100-200 ng/mL. The mean CyA level was 183.8+/-48.3 ng/mL (range 120.7-276.0 ng/mL) and the mean duration of CyA therapy was 10.9+/-1.9 months (range 8-12 months). After CyA therapy the mean 24 hr urinary protein excretion declined from 107.1+/-35.1 mg/m2/hr to 7.4+/-2.4 mg/m2/hr (P<0.001) and serum albumin increased from 3.3+/-0.6 g/dL to 4.3+/-0.3 g/dL (P<0.001). At a follow-up biopsy the histological grade of IgAN was improved in seven (50%) of the 14 patients, remained the same in three (21%), and was aggravated in four (29%). Serum creatinine, creatinine clearance, and blood pressure did not differ before and after CyA therapy. Two patients (14%) showed CyA-induced nephrotoxicity at the second biopsy. Our findings indicate that CyA therapy may be effective in reducing proteinuria and regressing renal pathology in a subset of children with IgAN.
