Objective To find out the clinical characteristics and prognostic risk factors of malignant hypertension (MHT) with pre existed chronic glomerulonephritis.Method The clinical and renal pathological data of 38 chronic glomerulonephritis patients with MHT hospitalized in our department from 1990 to 2002,and the associated factors for renal prognosis were analyzed. Results All the patients suffered from chronic glomerulonephritis.The ratio of male to female was 3 75∶1.The average age was (29 5?7 74)years old. The rates of recognition, therapy and control of hypertension before MHT onset were 75 7%, 13 5%and 5 4%respectively. IgA nephropathy was the most common pathological type.Of 38 cases,3 maintained normal renal function, 6 presented acute renal failure,13 presented chronic renal failure, and 16 had acute attack based on chronic renal failure. Twenty four patients were followed up for 1～6 months after antihypertensive therapy and renal function of 10(41 7%) was improved. 1 year renal survival rate of 20 patients was 55%. The analysis of risk factors showed that those patients who were possessed of positive hypertension family history(P=0 03), high SBP/DBP levels(P=0 023,0 047), and high scores of chronic index of renal pathology(P=0 032) had worse prognosis. The level of highest serum creatinine and the scores of chronic index of renal pathology were associated with 1 year renal survival(P=0 031,0 037).Conclusions MHT occuring in young patients with chronic glomerulonephritis is not rare, which becomes an important reason inducing rapidly decrease of renal function, especially in patients with IgA nephropathy. Actively antihypertensive therapy is helpful for renal function recovery. The low rates of recognition, therapy and control of pre existed renal hypertension may play key roles in the development of MHT. It is important to recognize and treat the hypertension at early stage of renal disease to improve the renal survival.

A series of [1,3]dioxolo[4,5-f]isoindolone derivatives were designed, synthesized and evaluated as inhibitors of acetylcholinesterases (AChE). Furthermore, their effects on memory impairment of mice induced by scopolamine were investigated with step-through test. The results suggested that most of the target compounds exhibited potential inhibition on AChE with IC50 values at micromolar range. Compounds I1 (IC50 value of 0.086 μmol · L(-1)) and I2 (IC50 value of 0.080 μmol · L(-1)) showed the strongest AChE inhibitory activity, which are equipotent to donepezil (IC50 value of 0.094 μmol · L(-1)). Moreover, compounds I1-I4 could improve the memory impairment induced by scopolamine in mice.

Objective To clarify the relationship between the basivertebral foramen (BF) and the retropulsed bone fragment (RBF) in thoracolumbar burst fracture (TLBF) and further explain the mechanism of RBF formation.Methods From June 2013 to June 2016,Sixty-two patients suffering from TLBF with RBF were collected.The characteristics of RBF as well as the parameters of vertebral body were studied using CT reconstruction imaging.In the transverse images,the lengths of RBF (RL) and vertebral body (VL) were measured.In median sagittal images,the heights and widths of RBF (RH,RW) and vertebral body (VH,VW) were also obtained.The ratios of different parameters of RBF and vertebral body (RL/VL,RW/VW,RH/VH) were calculated,and then defined the location relationship of RBF and BF.Eight frozen cadaveric spine were selected and evaluated by Micro-CT scans.Each vertebral body was divided into three layers (Superior,Middle,Inferior).Each layer was further divided into 9 regions (R1-R9),named as SR1-SR9,MR1-MR9,IR1-IR9.Microarchitecture parameters of each region in each layer,including bone volume fraction (BV/TV),bone mineral density (BMD),trabecular connectivity (Corn.D),and trabecular number (Tb.N) and thickness (Tb.Th) were calculated,and their differences were also analyzed to see if the trabecular bone distribution would be affected by BF.In vitro study,burst fractures were simulated on cadaveric spines by using bursting fracture simulator,aiming to observe the RBF morphology and imaging findings to future investigate the relationship between RBF and BF.Results The length and height of RBF were close to half of vertebral body length and height (RL/VL:0.497±0.059,RH/VH:0.485±0.036).The width of RBF was usually one-third of vertebral body width (RW/VW:0.319±0.025),which indicated that the fracture block was often located in the posterior of vertebral body above the BF.BV/TV,Tb.N in the MR2 and MR5 regions were lowest than other regions and the SMI of MR2 and MR5 was largest than others.SR5 was the lowest region in superior lawyer that was corresponded to regions most affected by burst fracture.In simulated burst fractures,the fracture line of RBF went across the vertex or upper surface of the BF and the lower boundaries of RBF were also the upper bound of the BF.Moreover,the damage sites of posterior longitudinal ligament were mainly located at the edge of the BF.Conclusion At the bone defect region,the BF is the weakest area in the vertebral body which may affect the distribution of trabecular bone surrounding it.When subjected to vertical violence,these regions undergo fracture first which impact the anterior and lower boundaries of RBF.Ultimately,RBF was produced upon the BF,involving all or part of the upper bound of the BF.
