Normalizing GFR with variables is important for non-cancer patients,especially for kidney donors.The most frequently evaluated variables are body surface area (BSA),extracellular fluid volume (ECV) and lean body mass (LBM).It is difficult to accurately quantify BSA and the power of BSA normalization decreases in children and obesity population.The ECV normalization is suitable for healthy children,but its clinical value decreases in patients with damaged renal function.The LBM can be accurately measured and has a larger serviceable range in the normalization.Although the influence factors of LBM should be extensively evaluated,the available data indicate that LBM is more suitable in the normalization of GFR than BSA and ECV.

Chinese Traditional and Herbal Drugs 2017;48(2):299-304
Objective: To develop the quality standard for Shenmai Dihuang Pills (SDP). Methods: The TLC methods applied to identify MoutanCortex, CorniFructus, Alismatis Rhizoma, and GlehniaeRadix in the formulation were carried out according to the methods recorded in general rules of Chinese Pharmacopeia (2015 edition, volume 4). The contents of psoralen, iso psoralen, and paeonol were analyzed by high performance liquid chromatography on a Diamonsil C18 column (250 mm ×4.6 mm, 5μm) with the mobile phase of acetonitrile (A)-0.1% formic acid (B) by gradient elution at a flow rate of 1.0 mL/min. The detection wavelength was set at 254 nm and the column temperature was controlled at 30℃. Results: There were good specificities of TLC for MoutanCortex, CorniFructu, Alismatis Rhizoma, and Glehniae Radix. The methodology validation for the assay of psoralen, iso psoralen, and paeonol presented that they were in good linear correlation in the ranges of 6.531-58.78, 6.115-55.04 and 20.40-183.6 μg/mL, with the regression equations of Y =1.523×104X-1.209×104 (r = 0.999 9), Y =1.809×104 X-1.523×104 (r = 0.999 9), and Y =2.760 ×104 X-1.683 ×104 (r = 0.999 9), respectively. The average recoveries were 100.4% (RSD 1.1%), 101.5% (1.3%), and 101.5% (0.79%).The content ranges of psoralen, isopsoralen, and paeonol from five different batches of SDP were 322.1-331.0, 298.0-350.1, and 929.5-982.7 μg/g, respectively. Conclusion: The established quality of TLC and HPLC methods are specific, reliable, accurate, and suitable, which can be successfully applied to the quality control for the preparation.

BACKGROUND:Foreign studies have found that the magnesium alloy stent is safe and effective, but there are few studies on the degradation performance of magnesium alloy stents in China.OBJECTIVE:To investigate the degradation of degradable AZ31 magnesium alloy stent in the rabbit abdominal aorta and the effect of degradation process on vascularization.METHODS:Twenty-eight rabbits were enrolled, and the degradable AZ31 magnesium alloy stent was implanted into the rabbit abdominal aorta. Postoperative abdominal aortic X-ray examination and histological observation were done at 30, 60, 90, 120 days after implantation.RESULTS AND CONCLUSION:(1) X-ray examination: 30 days after implantation, the stent expanded completely with structural integrity; 60 days after implantation, the stent deformation, partial stent fracture, and lose of support were found; 90 days after implantation, only a small amount of support rod residues were found, and the majority of the stent was degraded; and 120 days after implantation, there was no support rod residual, and the stent was degraded completely. (2) Histological observation: 60 days after implantation, the number of residual support rods was less than that 30 days after implantation (P< 0.05), the number value at 90 days after implantation was lower than that at 30 and 60 days after implantation (P< 0.05), and the number value at 120 days after implantation was lower than that at 30, 60, 90 days after implantation (P < 0.05), indicating that the number of residual support rods was negatively correlated with post-implantation days. The time for complete stent degradation was 124.8 days. The intimal area at 90 days after implantation was higher than that at 30, 60, 120 days after implantation (P < 0.05), while the lumen area was smaler than that at 30, 60, 120 days after implantation (P < 0.05). There was no significant difference in the intimal area and lumen area at latter three time points after implantation. To conclude, the degradation of the degradable AZ31 magnesium alloy stent in the rabbit abdominal aorta can be completed within 124.8 days, and at 90 days after the stent is implanted, vascular intimal hyperplasia and lumen stenosis are most serious, and then gradualy reduced.

Objective: To observe the effectiveness and safety of electroacupuncture (EA) plus Luohua Anshen oral liquid for patients with perimenopausal insomnia. Methods: A total of 66 participants who met the inclusion criteria were enrolled in the randomized controlled trial and allocated to a treatment group and a control group at a ratio of 1:1, with 33 cases in each group. Both groups were given Luohua Anshen oral liquid as a basic treatment. The treatment group was additionally given EA every other day, three times a week. Both groups were treated for four weeks and a four-week follow-up was conducted. The scores of Pittsburgh sleep quality index (PSQI), Kupperman index (KI) and traditional Chinese medicine sleep syndrome scale (TCMSSS) were recorded at pre- and post-treatment, and at the follow-up. Meanwhile, adverse effects were monitored and recorded. Results: After four-week treatment, the global scores of PSQI, KI and TCMSSS in both groups declined significantly (all P<0.05), and the decreases in the treatment group were more significant than those in the control group (allP<0.05). The global scores of PSQI, KI and TCMSSS in both groups at the follow-up visit were significantly different from the corresponding baseline (allP<0.05), while insignificantly different from those assessed at post-treatment (allP>0.05). The total effective rate was 93.9% in the treatment group, significantly higher than 72.2% in the control group (P<0.05). No significant adverse event was reported in this trial excepted one patient experienced slight dizziness in the first acupuncture treatment. Conclusion: EA plus Luohua Anshen oral liquid is safe for perimenopausal insomnia with satisfactory short- and long-term effectiveness, and it shows certain advantage compared with using Luohua Anshen oral liquid alone.

Heart transplantation is considered the best treatment modality for advanced heart disease.While old age has conventionally been considered a contraindication for heart transplantation due to the reported adverse effect of advanced age,however donor hearts' shortage continues to stimulate the discussion about the recipient's upper age limit.Our study was based on a retrospective analysis for the results of 52 (18%) patients aged 60 years and older undergoing heart transplantation between May 2008 and December 2015,and these patients were compared with 236 (82%) adult recipients who were younger than 60 years at the time of transplantation and during the same period.In older group,71% were males with the mean age of 63.38+3.55 years,and in younger group,83.4% were males with a mean age of43.72±11.41 years (P=0.27).Dilated cardiomyopathy was the most common indication for transplantation among patients in both groups (P=0.147).In older group,the 3-month survival rate was higher than that in younger group (P=0.587),however the 6-month survival rate showed no significant difference (P=0.225).Although the 1-year survival rate was higher in older group (P=0.56),yet the 3-year survival rate between the two groups showed no statistically significant difference (P=0.48).According to our experience among older heart transplant candidates who were 60 years and older,we believe that advanced age should not be an excluding criterion to cardiac transplantation.
