Objective: To investigate the association between the left ventricular hypertrophy (LVH) and blood pressure load (BPL) and circadian rhythm in hypertensive patients. Methods:Sixty patients with hypertension were studied by 24-hour ambulatory blood pressure monitoring ( ABPM) and colour Doppler echocardiography. Results: Daytime、 nighttime and 24-hour systolic blood pressure load (d-SBPL、n-SBPL、24h-SBPL) in hypertensive patients with LVH were significantly higher than those without LVH[(88.4?11.6) vs (79. 8?13. 4) ,P

Objective To determine the prevalence of renal artery stenosis (RAS) and the efficacy of percutaneous transluminal renal angioplasty (PTRA) and stenting in patients with documented coronary artery disease.Methods Selective renal artery angiography or abdominal digital subtraction angiography was performed immediately after coronary angiography to detect and quantify RAS in 200 consecutive patients with known or suspected coronary artery disease. Eight severe stenotic renal arteries in 7 patients were treated with PTRA and stenting. All the lesions are considered to be atherosclerotic. Results RAS (defined as ≥50% diameter stenosis) was detected in 21 of 200 patients (10.5%) and 19 of 99 patients with coronary artery disease (19.2%) who had at least one coronary artery of ≥50% diameter stenosis. Procedure success rate was 100% in the 7 patients received PTRA and stenting. Blood pressure control improved in 74.1% patients with hypertension. Angiographic follow up was done in 3 patients in 3 to 9 months and no restenosis was found in the vessels.Conclusions It is necessary to routinely perform RAS for the patients with coronary artery discase undergoing coronary angiography to identify RAS, especially in those associated with hypertension, so as to diagnose and treat RAS in early stage. PTRA and stenting carries high success rate and appears to be an effective and safe treatment for RAS.

Objective To explore the effects of different period of insulin-like growth factor-1(IGF-1)on B cell lymphoma/leukeamia-2 gene(BCL-2)and BCL-2 associated X protein(BAX)of myocard in mice with viral myocarditis.Methods Male Balb/c mice were randomly divided into control group,coxsackie viral B3(CVB3)infection group(infection group),IGF-1-treated group in earlier stage(0-6 d)and acute stage(7-13 d),injected IGF-1 of exogenous in abdominal cavity [30 ?g/(kg?d)].Animals were killed at the 14 day.The immunohistochemical studies and medical imagine analysis system were performed to evaluate the expression of BCL-2 and BAX in myocardial tissue.Results In infection group,the expression of BCL-2 reduced and BAX increased than those of control and treatment group(Pa

Objective To investigate the relationship of 24 h urinary potassium (K) measurement and the symptoms change in ketamine-associated cystitis.Methods Forty-three ketamine-associated cystitis patients (29 male cases,14 female cases) were analyzed.The average age was 22 (17-29) years.Thirty-two patients without indwelling urinary catheter were categorized as group A,while the other 11 patients with indwelling urinary catheter were in group B.The therapy regimes consisted of anti-inflammatory,antioxidant,relieving spasm and pain,improving the microcirculation and repairing the bladder epithelium barrier.Thirty healthy adults were selected as the controls.Urinary K,sodium (Na) and creatinine (Cr)were determined in 24 h urine samples from all patients and controls before and after treatments.24 h urinary Cr was used as the internal standard.24 h urinary K and Na concentrations of the patients were calculated as relative to the Cr concentrations.The pelvic pain and urgency/frequency symptom (PUF) was used for evaluation before and after the treatments.The differences of urinary K were compared within each group and between groups before and after treatments.In addition,relationship of urinary K and PUF were assessed.Results Urinary Cr concentrations in all groups were not significantly different (P ＞ 0.05).Patients in group A had lower average K-to-Cr ratios than those patients in group B and controls (A 1.80 ± 0.67 vs.B 6.22±0.92 mmolK/mmol Cr,P=0.0001; A 1.80±0.67 vs.controls 6.47 ±0.97 mmol K/mmol Cr,P =0.0001) before treatments.But the ratios of K-to-Cr in group A were not significantly different with group B and controls after treatments (A 6.23 ± 1.42 vs.B 6.02 ± 0.98 mmol K/mmol Cr,A 6.23 ± 1.42vs.controls 6.47 ±0.97 mmol K/mmol Cr,F =0.698,P =0.472).PUF in both groups was not significantly different before treatments.For group A,PUF was negatively correlated with urinary K before and after treatments (before: r=-0.637,P=0.0001; after: r=-0.427,P=0.015).For group B,PUF had no correlation with urinary K before treatment (r=0.581,P =0.188),while there was a negative correlation between them after treatments (r =-0.779,P =0.005).PUF scores in all patients (group A + B)were significantly decreased after treatments when compared to those before treatments (18.12 ± 2.83 vs.22.77 ± 3.63,P =0.0001).Conclusion Urinary potassium measurement may have a role in evaluating the disease status and efficacy of treatments of patients suffered from ketamine-associated cystitis.

Objective: To investigate the effects of pravastatin o n atherosclerotic plaque and cardiovascular events. Methods: Fifty- seven patients with coronary artery disease (44 male and 13 female, 58.4±11.3 y ears) were randommized into pravastatin and control groups. The patients in prav astatin group were administered 10 mg of pravastatin from the night of coronary angiography day. After 7.3 months (mean) of follow-up, plasma lipid parameters and coronary angiograph were repeated. Results: (1) A favorable effect on plasma lipid parameters was found. After administration, total choles terol(TC), low density lipoprotein cholesterol (LDL-C) and triglyceride(TG) red uced by 15.0% (P<0.01), 18.0% (P<0.01) and 6.0%, respectively. High den s ity lipoprotein cholesterol(HDL-C) increased by 10.6%. However, in control grou p, TC and LDL-C showed a tendency to reduce, but no significant difference was found between those of pre- and post-administration. (2)There was no significa nt difference in luminal diameter between pre- and post-administration in both groups. (3) Cardiovascular events in pravastatin group was significantly lower than those in control (P<0.05). (4) Pravastatin had no significant effect on HR, BP and left ventricular ejection fraction in both groups. Conclusio n: Pravastatin can stabilize coronary atherosclerostic plaque and reduce the incidence of cardiovascular events by improving plasma lipid parameters.

Objective To investingate the iodine-nutritional status of the rural children form 8 to 10 years old after salt iodzation had been implemented in Qiannan State.Methods The size of thyroid gland waft measured by palpation in 421 rural children aged 8～10 years old in Qiannan State.Calorimetric eerie-arsenic assay and vitriolic ammonium assimilmion were used for testing urinary iodine,while Rsvens test was used to test the intelligent quotient (IQ).Results The rate of goiter was 5.0%(21/421).The median of urinary iodine Was 331.2μg/L The average IQ was 93.32±18.68 of the children aged 8～10.The IQ of children with different iodine-nutritional level was significantly different(P＜0.05).Conclusions The children's iodine nutrition in Qiannan State has been improved after the salt adds the iodine.Their intelligence level is quite normally.Iodine dificiency disease has been eliminated according to the national standard in terms of 8～10 year old child ufinaty iodine level and goiter rate.

Objective: To investigate the relationship between serum HGF levels and clinical severity of essential hypertension (EH). Methods: The serum HGF concentrations of 44 patients with EH were measur ed by ELISA. Results: The serum HGF levels in patients with EH w ere higher than that in control. Furthermore, the serum HGF levels of EH patient s with coronary atherosclerosis (CAS) were significantly higher than those of EH patients without CAS ［(920.8±250.0） pg/ml vs （747.9±132.1） pg/ml, P <0.01］ or control ［（643.8±98.2） pg/ml, P<0.01)］.The changes of HGF l evel were correlated with the clinical courses (r=0.63, P<0.01) and stag es (r=0.69, P<0.01) of hypertension. Conclusion: HGF may be considered as a new index for the severity of hypertension and an useful bio chemical parameter for estimating the development of atherosclerosis.
