Objective To study the effects of salt restriction on blood pressure in hypertensive patients with chronic kidney disease(CKD).Methods From July to December,2006,26 hypertensive CKD patients with 24 h urinary sodium excretion(UNa)over 100 mmol/d were enrolled and received dietary education and sodium spoon.Their BP level,blood/urine electrolytes,serum creatinine and amount of urinary protein were measured before-and after-8 weeks.Anti-hypertension therapy kept unchanged during the observation period and those with UNa decreased less than 10% at the end of observation were considered as salt restriction failure.Results Eighteen patients succeeded with a reduction of UNa from(243.8?71.2)mmol/d to(135.0?49.1)mmol/d(P

Glucose-6-phosphatedehydrogenase( G6PD) is the main regulatory enzyme of pentose-phos-phate pathway,which plays an important role in maintaining the balance of cell energy and redox reactions in the cell. G6PD deficiency is the most common hereditary erythrocyte enzyme deficiency disease. There are no effective treatments for the disease. Currently,the key of control and treatment is to make a definitive diagnosis in time and keep away from related risk factors of the disease. At present,the main clinical diagnostic method is the detection of G6PD enzyme activity,but it is limited in accuracy of detecting the heterozygote females. It has already been confirmed at home and abroad that G6PD heterozygote is a risk factor of neonatal hyperbilirubi-nemia. Thus,the detection method of different genotypes of G6PD deficiency at the same time is urgently needed in clinical diagnosis. This paper reviews on recent research progress of the G6PD deficiency disease.

Aim To establish and evaluate Sprague-Dawley (SD) rats model with yang-deficiency and constipation at the direction of traditional Chinese medicine theories. Methods Rats model with yang-deficiency and constipation were induced by orally administration of white vinegar and active carbon-ice water. Changes of model rats in common biological characteristic, the number and time of excretion stool, colonic electromyography, gastrointestinal hormones and intestinal neurotransmitters were observed. Results Compared to the control group: changes of the model group in common biological characteristic including abdominal distension, puffed and withered hair, sluggish response, falling body weight, black and dry stool; Excretion time of the first granule stool became longer; Number of excretion stool within six hours became shorter; Intestine pushing rate decreased, and secretion of gastrointestinal hormones and intestinal neurotransmitters disordered, etc. After being treated with Tongbianling, the syndrome and indexes of model rats markedly improved. After 6 days′ resume, the model group in the experiment of excreting stool had markedly signification in comparison with the control group. Conclusion SD rats model with yang-deficiency and constipation could be stably established by administering white vinegar and active carbon-ice water.

Objective To retrospectively analyze the result of hemoglobin(Hb)test by using full-automatic Hb electrophoresis and evaluate the its significance in hemoglobinopathy.Methods The data of patients who underwent Hb electrophoresis test and regular blood tests in the hospital from January 2011 to December 2013 were included in the study.The test results were recorded including mean corpuscular volume(MCV),mean corpuscular hemoglobin(MCH)and results of Hb electrophoresis test.Final diag-nosis were made for suspected patients by using genetic testing,then disease detection rates and gene coincidence rates and constitu-ent ratios were calculated.Results 12 898 cases were included in the study,after statistical analysis the MCV was(85.32±13.61) fL,MCH was(29.87±6.44)pg.By using automatic hemoglobin electrophoresis,1 315 cases were found to be positive,in which 568 were male,747 were female,the detection rate was 10.19%.In the 1 315 patients,there were 761 cases suspectedα-thalassemia,ac-counted for 5.90%.There were 495 cases of suspectedβ-thalassemia,accounted for 3.84%,11 patients with HbJ(0.08%),15 pa-tients with HbK(0.12%),9 patients with HbG(0.07%),3 patients with HbD(0.02%),21 patients with HbE(0.16%).The sus-pected case′s final diagnosis were made by using genetic testing,α-thalassemia gene′s coincidence rate was 80.55%,β-thalassemia gene′s coincidence rate was 96.77%.Conclusion Automatic hemoglobin electrophoresis detection is of great significance for the di-agnosis of hemoglobinopathy.

Objective To investigate the effect of cardiotrophin-1 (CT-1) mediated by recombinant adenovirus (Adv) on the neural differentiation of bone marrow mesenchymal stem cells (rBMSCs) of rats.Methods The rBMSCs were isolated and cultured by attachment method.The surface marker protein was identified by flow cytometry.The rBMSCs were divided into 4 groups:control group,AdV enhanced green fluorescence protein (Adv-EGFP) + induction group(empty virus group),CT-1 group and induction group.The cells were transfected by Adv in the corresponding multiplicity of infections.Each group was induced by neural induction medium except for control group.The cells morphological changes were observed by microscope and the expressions of Nestin,neuronal nuclei (NeuN) and glial fibrillary acidic protein(GFAP) were detected respectively by cellular immunofluorescence at 5 h,3 d and 7 d after induction.Results After induction treatment,neuron-like cells morphological changes were observed in all the groups except for control group,among which the most obvious change was found in CT-1 group.The positive rate of Nestin was the highest at 5 h after induction.Positive rate of CT-1 group[(86.31 ± 4.27)％] was higher than any other groups,the differences were statistically significant (all P ＜ 0.001);after which its positive rate gradually declined,the positive rate of CT-1 group changed more obviously than other groups,and the differences were statistically significant (all P ＜ 0.001).The difference in Nestin positive rate between the empty virus group and induction group was not statistically significant (all P ＞ 0.05) at various time points.The NeuN and GFAP could be observed in CT-1 group at 5 h after induction.Then the positive rate of NeuN and GFAP increased gradually,and climbed to the highest point [(64.41 ± 3.65)％,(47.14 ± 4.29)％] on 7 d after induction.Positive rate of NeuN and GFAP in CT-1 group at various time points were higher than that of other groups,and the differences were statistically significant (all P ＜0.001).The difference of NeuN and GFAP positive rate between the empty virus group and induction group was not statistically significant (all P ＞ 0.05).Conclusion CT-1 could promote the neural differentiation of rBMSCs.

Objective To compare left ventricular (LV)synchronization of direct His-bundle pacing (DHBP)and right ventricular apical pacing (RVAP)with two-dimensional speckle tracking imaging (2D-STI)and tissue Doppler imaging (TDI),and discuss the diagnostic value of 2D-STI and TDI in evaluation of left ventricular systolic synchronicity.Methods Twenty-four patients implanted with DHBP and RVAP were observed.Conventional echocardiography examination were undergone both at the mode of DHBP or RVAP respectively.The time to peak radial strain of LV 1 8 segments were derived from the parasternal short-axis views by 2D-STI,then calculated the standard deviations (SD ) and the maximal temporal difference of LV 1 8 segments (Trs-SD and Trs-Dif),and the interval of time to peak radial strain between the anteroseptal wall and the posterior wall (Tas-post).The time to peak systolic velocity of LV 12 segments were derived from the apical axis views by TDI.The SD and the maximal temporal difference of 1 2 segments (Ts-SD and Ts-Dif)were calculated as the LV dyssynchrony index.Results All the systolic synchrony parameters derived from 2D-STI and TDI were more significantly shortened in DHBP than in RVAP (all P <0.01).For DHBP,the detection rate of LV synchronization was higher by 2D-STI than by TDI.For RVAP the detection rate of LV dyssynchronization was also higher by 2D-STI than by TDI with RVAP lead (all P <0.05).Conclusions DHBP is more beneficial than RVAP in LV syschronization and LV function,RVAP may induce left ventricular systolic asynchrony.Both 2D-STI and TDI can assess the LV synchronization quantitatively,but 2D-STI may be more superior on the detection rate than TDI.
