RESUMEN
Objective To understand the prevalence,treatment and influence factors of hypertension in maintenance hemodialysis (MHD) patients in Anhui Province.Methods A total of 2724 adult patients on MHD from January 1st 2014 to March 31st 2014 in 26 hospitals of southern,northern and central Anhui Province were investigated.Their demographic characteristics,primary disease,complications,medications,dialysis and laboratory examination were explored.The prevalence treatment rate and control rate of hypertension were analyzed.Associated factors for controlling hypertension [systolic blood pressure (SBP) ＜ 140 mmHg and diastolic blood pressure (DBP) ＜ 90 mmHg] were assessed by logistic regression analysis.Results (1) The prevalence of hypertension in the hemodialysis patients was 87.0％.Their treatment rate and control rate were 93.2％ and 23.9％ respectively.The average of SBP was (145.90±21.18) mmHg,and the DBP on average was (83.60± 12.21) mmHg.The most commonly used anti-hypertensive drug is calcium channel blocker (88.2％).Over one third (45.7％) of patients were treated with two kinds of anti-hypertensive drug,26.2％ with 1 kind,21.7％ with 3 kinds,and 6.4％ with 4 kinds or more.(2) Compared with non-hypertension patients,patients with hypertension have older age,higher body mass index (BMI),phosphorus,SBP and DBP,as well as lower hemoglobin and Kt/V (all P ＜ 0.05).(3) The multivariate logistic regression analysis showed that Ca ＞ 2.50 mmol/L (OR=2.084,95％CI 1.008-4.307,P=0.047) positively correlated with controlling hypertension,while smoke (OR=0.594,95％CI 0.356-0.911,P=0.046) and BMI 18.5 ～ 23.9 kg/m2 (OR=0.516,95％CI 0.293-0.907,P=0.022) negatively correlated with it.Conclusions High prevalence yet low control rate of hypertension in MHD patients in Anhui Province were observed.Hypocalcemia may be a protective factor for hypertension control,while smoke and BMI may be risk factors for it.
RESUMEN
<p><b>OBJECTIVE</b>To investigate the tissue distribution of berberine in rats after oral administration of Rhizoma Coptidis with Cortex Cinnamomi powder.</p><p><b>METHOD</b>After oral administration of Rhizoma Coptidis powder and Rhizoma Coptidis with Cortex Cinnamomi powder (6:1) at the dosage of 6 g x kg(-1) and 6.6 g x kg(-1) respectively per day for 1 week, the drug concentrations in various tissues were determined by HPLC method. The variations of berberine concentrations in tissues of two treated group of rats were compared by t test using software of SAS.</p><p><b>RESULT</b>With repeated administration of Rhizoma Coptidis powder, berberine distributed widely in tissues of rats and the concentrations of berberine in tissues increased, yet berberine existed mainly in liver. Berberine concentrations in all organs investigated in the group of rats treated with Rhizoma Coptidis and Cortex Cinnamomi powder showed obvious difference with those of the group of rats treated with Rhizoma Coptidis powder (P < 0.01). The berberine concentrations increased in heart, liver and kidney, while decreased in spleen and lung.</p><p><b>CONCLUSION</b>Rhizoma Coptidis coadministration with Cortex Cinnamomi can obviously change the distribution of berberine in rat organs.</p>
