Objective To investigate the incidence and influencing factors of aldosterone escape in patients with non-diabetic nephropathy by RASI-therapy. Methods A total of 104 patients with non-diabetic nephropathy were treated with ARB or combination therapy of ACEI and ARB in a mean follow-up period of 12 months. Aldosterone escape was determined according to the change of plasma aldosterone concentration before and after treatment during 6-month and 12-month ACEI/ARB treatment, while the influencing factors of aldosterone escape in patients with non-diabetic nephropathy was also analyzed after therapy with RASI . Results In 12 months, the incidence of aldosterone escape was significantly higher than that in 6 months (26.92% vs. 14.42%, P = 0.007). After 12-month treatment, the difference was statistically significant in incidence of aldosterone escape among different stages of CKD (P = 0.027). Compared with 6-month incidence of aldosterone escape in the losartan group, 12-month incidence increased evidently (P = 0.020). The Ald level was positively correlated with urinary protein excretion and the Scr level (r = 0.431, P = 0.003 and r = 0.336, P = 0.009, respectively), and negetively correlated with levels of the eGFR (r = -0.275, P = 0.006). Univariate Logistic regression demonstrated that risk factors of aldosterone escape included pre-treatment values of the urinary protein excretion (OR = 3.671, P = 0.028) and the eGFR (OR = 0.972, P = 0.019). Multivariate Logistic model revealed pre-treatment values of the eGFR was positively associated with aldosterone escape (OR = 0.970, P = 0.012). Conclusion The incidence of the aldosterone escape increases along with the time of treatment. Renal function has correlated with aldosterone escape and pre-treatment value of the eGFR is an independent risk factor of aldosterone escape.

BACKGROUND: In China, although microscope-assisted anterior cervical decompression has been performed by many spine surgeons in recent years, the application of microscope still needs to be further promoted in China. Therefore, it is necessary to systematically evaluate and analyze the clinical efficacy of cervical spondylopathy by comparing patients under microscope-assisted anterior cervical approach to traditional anterior cervical approach. As a result, it can provide the evidence for clinical decision in these cervical spondylopathy patients. OBJECTIVE: To systematically evaluate the effect between microscope-assisted anterior cervical approach and traditional anterior cervical approach in cervical spondylopathy patients. METHODS: Databases such as Medline, Embase, PubMed, Web of science, CBM, Wangfang databases, VIP, and CNKI were searched from inception to July 2019 to find literature related to microscope-assisted anterior cervical approach and traditional anterior cervical approach in treatment of cervical spondylopathy. Two investigators evaluated the researches independently and compared the operative time, intraoperative blood loss, the preoperative and postoperative Japanese Orthopedic Association score, neurological success rate, the preoperative and the postoperative visual analogue scale score, and the complication rates between two groups. The quality of the included literature was evaluated by the modified Jadad scale, the modified Newcastle Ottawa score and the methodological index for non-randomized-studies. The correlative clinical outcome in inclusive research was analyzed systematically by using Stata 12.0 Software. RESULTS AND CONCLUSION: (1) Twelve studies were accorded with the inclusion criteria, containing 892 cases (438 cases in the microscope-assisted group, while 454 cases in the traditional group). (2) There were no significant differences in the preoperative Japanese Orthopedic Association score (WMD=-0.100, 95%C/(-0.459, 0.259), P=0.585), operative time (WMD=6.852, 95%C/(-0.446, 14.149), P=0.066), the preoperative and postoperative visual analogue scale score (WMD=0.293, 95%C/(-0.023, 0.608), P=0.069; WMD=-0.T\8, 95%C/(-1.495, 0.059), P=0.070) between two groups. (3) Postoperative Japanese Orthopedic Association score (WMD= 1.310, 95%C/(0.621, P < 0.001), the rate of neurological success (WMD-4.639, 95%C/(0.294, 8.984), P=0.036) in the microscope-assisted group were higher than those in the traditional group. The intraoperative blood loss (l/MMD=-18.068, 95%C/(-24.504, -11.632), P< 0.001) and the rate of complication (RR=1.068, 95%C/(1.012,1.126), P=0.002) in the microscope-assisted group were significantly lower than those in the traditional group. (4) Performing anterior cervical approach under microscope has a better clinical effect than using traditional anterior cervical approach in the treatment of cervical spondylopathy, but more high-quality clinical studies are needed to verify it.

Using a bioassay-guided fractionation technique, two compounds were isolated from the roots of Incarvillea younghusbandii Sprague through silica gel, reverse-phase C18 column chromatography and reverse-phase HPLC. Their structures were identified as acteoside (1) and isoacteoside (2) by ESI-MS, GC-MS, 1D- and 2D-NMR. 1 and 2 showed *OH scavenging capacity similar with benzoic acid, higher O2*- (or *OH) scavenging capacity than ascorbic acid, far higher hepatic LPO inhibitory activities than 2, 6-di-tert-butyl-4-methylphenol (BHT) or ascorbic acid, and more powerful effect on protecting erythrocytes from oxidative damage than ascorbic acid. The *OH scavenging capacity was positively proportional to the concentrations of 1 and 2 ranging from 0.015 6 to 0.500 0 mg x mL(-1). The hepatic LPO inhibitory activities increased with the increasing concentrations of 1 and 2 from 0.001 9 to 0.250 0 mg x mL(-1), but decreased slightly with the increasing concentration from 0.250 0 to 1.0000 mg x L(-1).

Objective To investigate the biomechanical properties of principal tensile trabecular bone in proximal femur and provide experimental evidences explaining the osteonecrosis of femoral head resulting from femoral neck fracture.Methods Eight human cadaveric femurs,with no deformities,fractures,and other lesions,were selected.The principal tensile trabecular bone system was devided into three parts from the exterior to the interior.Specimens were taken in each part along or perpendicular to the direction of principal tensile trabecular,respectively.Mechanics tests were performed by BOSE Enduratec ELF 3200.The ultimate tensile and compressive strength,yield tensile and compressive strength and elastic modulus of principal tensile trabecular bone in proximal femur were obtained.Results The tensile properties were higher than compressive properties in exterior parts,especially the tensile biomechanical properties along the direction of principal tensile were significantly higher than the compressive biomechanical properties in that direction.In the meddle part,the compressive properties were higher than the tensile properties both along the directions of principal compression and principal tension.In the interior part,the compressive properties were higher than the tensile properties along the direction of principal compressive trabecular bones,the tensile properties were higher than the compressive properties along the direction of principal tensile trabecular bone.Conclusion The major function of exterior part of principal tensile trabecular bone is loading tensile stress,that of the middle part is loading compressive stress,and that of the interior part is loading compressive stress along the direction of principal compression,while the major function along the direction of principal tensile trabecular bone is loading tensile stress,which indicate that the structure of trabecular bone is anisotropic and adapted to its function.

ObjectiveTo evaluate the efficacy and safety of spironolactone in treatment NYHA (New York Heart Association) class Ⅰ - Ⅱ heart failure patients. MethodsEighty eight patients with NYHA classⅠ- Ⅱheart failure were randomized to sprionolactone or placebo groups.Patients were assessed by echocardiography and 6-minute walking test (6MWT) ,plasma aldosterone and NT-proBNP were measured before and 6 months after treatment; serum potassium and creatinine were monitored through the study. ResultsThe E/A and E/E' in spironolactone group were significantly lower than those of control group (1.2±0.7 vs. 1.7±0.6, P=0.007;15.2±2.3vs. 17.7±3.0, P=0.000). No differences were observed in left ventricular end-diastolic diameter (LVEDD) and left ventricular ejection fraction (LVEF)between two groups after treatment. Left ventricular mass index (LVMI) in spironolactone group decreased after theatment [(117 ±27) g/m2 vs.(112 ± 19) g/m2,P = 0.044]. Plasma aldosterone level in spironolactone group after treatment was significantly lower than that of control group [ ( 157 ± 16) ng/L vs.( 165 ± 16) ng/L, P =0. 021 ]. Although there were no differences in plasma NT-proBNP level between two groups after treatment, it decreased significantly comparing with that of before treatment ( P = 0. 000). No differences were observed in serum potassium and creatinine between two groups after treatment. However serum potassium and creatinine in spironolactone group increased significantly after treatment [ ( 83 ± 18 )pmol/Lvs. (87 ± 22) μmol/L, P =0.047; (4.4 ±0.4) mmoL/L vs. (4.5 ±0.6) mmol/L, P =0. 012]. ConclusionSpironolactone can alleviate cardiac remolding and diastolic function in NYHA classⅠ - Ⅱ heart failure patients.
