Objective To explore the establishment methods of animal models of adult growth hormone deficiency, and to provide a good model for experimental research and treatment for abnormal bone metabolism caused by growth hor-mone deficiency.Methods The methods of establishment of animal models of adult growth hormone deficiency were re-viewed and evaluated refering to literature.Results There were three methods including spontaneous lack-of, pituitecto-mized and gene knockout can establish animal models of adult growth hormone deficiency.Conclusions Hypophysecto-mized animal models are inexpensive and easy to create, but not suitable for studying the relationship between growth hor-mone and bone metabolism.Spontaneous lack-of and gene knockout models are specific growth hormone deficiency and of great research significance in exploring the relationship between growth hormone and bone metabolism.

Aim To investigate the protective effect of ginsenoside Rb1 against apoptosis induced by H_2O_2. Methods H_2O_2 was used to build an oxidative stress-induced injury model in neonatal rat cardiomyocytes. After treated with gensenoside Rb1(20, 40, 80 mg?L -1),the apoptosis rate, the content of malondialdehyde (MDA), and the activity of superoxide dimutase (SOD) of the cardiomyocytes were examined. The intracellular calcium indicated by the fluorescence in cells were measured by the laser confocal microscope. Results Compared with the model group, the apoptosis rate and the content of MDA of the cardiomyocytes decreased greatly (P

Objective To study whether the effects of bone mineral density by a kidney-tonifying herbal fufang treatment in senile osteoporosis mice (P6) is by the mechanism of improving the expression level of GH mRNA and IGF-1 mRNA. Methods The experimental points four groups as following:SAMR1 mice which feed saline lavage,SAMP6 divid as saline lavage group,subcutaneous injection of rhGH group and a kidney-tonifying herbal fufang treatment group. All intervention is one time everyday. After 3 months and 6 months intervention,we measure the BMD and the expression level of the GH mRNA and of IGF-1 mRNA. Results After 3 months intervention,the BMD of R1 group and the Kidney group were higher than the P6 blank group;but there is no difference in BMD between RhGH group and the P6 blank group. The effect of GH mRNA and IGF-1 mRNA expression levels:the R1 group,rhGH and kidney group were higher than the P6 blank group. After six months intervention,the BMD of the rhGH group and kidney group are higher than the P6 blank group. GH mRNA and IGF-1 mRNA expression levels:GH group and kidney group are higher than the P6 blank group. The expression level of GH mRNA and IGF-1 mRNA in four groups has positive correlation. After six months intervention ,we found the positive correlation between the expression level of GH mRNA and IGF-1 mRNA and each part of the whole body BMD. Conclusion A kidney-tonifying herbal fufang can improve the bone mineral density of P6,and its mechanism may be related to improve expression level of GH mRNA and IGF-1 mRNA.

Objective To analyze the efficacy and hemodynamic changes in patients with complex symptomatic middle cerebral artery stenosis after Solitaire AB stent implantation.Methods From June 2013 to June 2016,7 consecutive patients with complex symptomatic middle cerebral artery stenosis treated with Solitaire stents at the Department of Neurology,the Third People's Hospital of Hubei Province were enrolled retrospectively.The stenosis rate ≥70% was confirmed by digital subtraction angiography (DSA).Of the 7 patients,5 were male and 2 were female,with an average age of 70±8 years.The general data of the patients were documented,including clinical symptoms,modified Rankin scale(mRS)score,stenosis degree,vascular pathways LMA classification and Mori typing for stenosis,and postoperative residual stenosis or restenosis.The hemodynamic parameters at day 1,7,and 3 months before and after procedure were compared.Results All patients were successfully implanted with the Solitaire AB stents.(1) Of the 7 patients,the Mori type A of stenosis lesions was in 4 cases,B in 2 cases,and C in 1 case.The LMA typing of vascular approaches were Type Ⅲ in 3 cases,type Ⅱ in 4 cases.The preoperative stenosis rate was 80±7%,the residual stenosis rate was 24±13%,and there were no operation-related complications.No ischemic events occurred during the follow-up period.(2) Before stent implantation and at 1 d,7 d,and 3 months after procedure,the peak systolic velocity (PSV) were 297±41,144±34,145±27,and 143±40 cm/s,respectively,the end diastolic velocity (EDV) were 159±22,68±16,68±14,and 66±17 cm/s,respectively,and the pulse index (PI) were 0.67±0.06,0.80±0.08,0.80±0.07,and 0.82±0.06,respectively.PSV,EDV,and PI at 1 d,7 d,and 3 months were improved compared with before procedure (all P<0.05),There were no significant differences at all time points in the pairwise comparison PSV and EDV and PI at all time points after the procedure (all P>0.05).Conclusions Initial analysis showed that no procedure-related complications were observed in the treatment of vascular tortuosity and complex middle cerebral artery stenosis with the Solitaire stents.The short-term curative effect is exact;However,it still needs to be validated further.

ObjectiveTo investigate the effect of finasteride on hemorrhage in peri-operation of transurethral plasmakinetic enucleation of prostate (TUPKEP).Methods150 patients with benign prostatic hyperplasia (BPH) were randomly divided into 3 groups:control group without finasteride (n= 50),treatment groupl 1 with finasteride 5 mg daily for 7 days(n= 50) and treatment group 2 with finasteride 10 mg daily for 7 days(n= 50) before and after operation.All patients received TUPKEP and the data were recorded,including total blood loss,operation time,amount of washing fluid during operation,blood loss of per gram tissue,blood loss per minute,washing time after operation,amount of washing fluid after operation,and rebleeding rate within 3 months after operation.ResultsThe 150 patients successfully received TUPKEP.The total blood loss,amount of washing fluid during operation,operation time,blood loss per gram tissue,amount of washing fluid after operation,washing time after operation and rebleeding rate within 3 months after operation in treatment group 1 and 2 significantly reduced as compared with control group (P＜0.05).The blood loss per minute were (1.77±0.89) ml/min,(1.71±0.82) ml/min and (1.70±0.81) ml/min in 3 groups,respectively,and there were no significant differences among groups (P＞ 0.05).There were no significant differences between treatment group 1 and 2 in the total blood loss,operation time,amount of washing fluid during operation,blood loss of per gram tissue,blood loss per minute,washing time and amount of washing fluid after operation (P＞0.05).The rebleeding rate within 3 months after operation in treatment group 1 (8/35) and treatment group 2 (3/26) decreased as compared with control group (17/39) (x2= 3.544 and 7.523,P=0.016 and 0.025)and it was lower in treatment group 2 than in treatment group 1 (x2 = 1.293,P = 0.044).Conclusions The application of finasteride in peri-operation of TUPKEP can reduce hemorrhage.
