BACKGROUND: Renin-angiotensin-aldosterone system existed in bone tissue. Recent studies on antihypertensive drugs found that angiotensin converting enzyme inhibitor type antihypertensive drug was possibly effective for osteoporosis. Perindopril is one of the commonly used antihypertensive drugs. Whether perindopril affected bone metabolism or could be used in anti-osteoporosis has not been reported.
OBJECTIVE: To observe effects of perindopril on bone metabolism in a rat model of osteoporosis induced by retinoic acid.
METHODS: Fifty Sprague-Dawley rats were randomly divided into five groups, with ten in each group. In the model group and each perindopril groups, rats were intragastricaly administered retinoic acid solution 80 mg/kg per day. After successful model establishment, rats in different perindopril groups were intragastrical y administered perindopril 2, 4 and 8 mg/kg per day, once a day, for 42 consecutive days. In the normal control and model groups, rats were given an equal volume of distil ed water. Serum calcium, phosphorus, alkaline phosphatase, bone mass and bone mineral density were detected in each group. Expression of bone specific alkaline phosphatase and tartrate-resistant acid phosphatase mRNA in bone tissue was determined.
RESULTS AND CONCLUSION: Compared with the model group, after treatment with perindopril, serum calcium and phosphorus levels were increased, alkaline phosphatase activities were significantly decreased, bone mass and bone mineral density were obviously increased in rats with retinoic acid-induced osteoporosis. Expression of bone specific alkaline phosphatase mRNA was higher in the perindopril 8 mg/kg group than in the perindopril 2 and 4 mg/kg groups and model group. Tartrate-resistant acid phosphatase mRNA expression was higher in the perindopril 8 mg/kg group than in the model group. These results indicated that perindopril could improve partial bone metabolic biochemical markers in osteoporosis rats, promoted bone formation by up-regulating bone specific alkaline phosphatase mRNA expression, and had a certain preventive effect on retinoic acid-induced osteoporosis.

Objective To compare the therapeutic effect between three cannulated screws and proximal femoral locking plate in treatment of femoral neck fracture.Methods A total of 75 patients were included,the three cannulated screws group contained 31 patients,and the proximal femoral locking plate group contained 44 patients.The clinical healing time,hip function score at last follow-up and postoperative complication were compared.Results All patients were followed up for 13-18 (15.3 ± 3.2) months.The excellent and good rate of proximal femoral locking plate group was 95.5％ (42/44),and three cannulated screws group was 83.9％(26/31),there was no statistical difference between the two groups (P ＞ 0.05).The clinical healing time of fracture and hip function score at last follow-up in proximal femoral locking plate group were significantly better than those in three cannulated screws group [(14.6 ± 1.7) weeks vs.(18.1 ± 4.9) weeks,(90.9 ± 3.5) scores vs.(82.3 ± 8.3) scores],there were statistical differences between the two groups (P ＜ 0.05).Conclusions Proximal femoral locking plate provides short clinical healing time of fracture,stable fixation,good biomechanical properties and a low rate of postoperative complication in treatment of femoral neck fracture.It is one of the ideal methods in treatment of femoral neck fracture.

Objective To explore the impact of morphological changes of mitral valve coaptation on ischemic mitral regurgitation (IMR),and observe coaptation image of mitral valve in systole in patients with IMR by using real-time three-dimensional transesophageal echocardiography (RT3D-TEE).Methods RT3D-TEE was performed on 112 patients with IMR and 38 patients without MR as the control.Patients with IMR were divided into group of mild IMR (n =46),group of moderate IMR (n =45) and group of severe IMR (n =21),according to the severity of mitral regurgitation.Mitral valve quantification (MVQ)software of Qlab 8.1 was used for image post-processing of RT3D-TEE.The coaptation parameters was measured,included length of anterior combination(LCA3dlf),length of posterior combination(LCP3dlf),area of anterior combination(A3DTANT) and area of posterior combination (A3DTPOST) at end-systole.Then,these coaptation parameters of mitral valve were compared statistically.Logistic regression assessing was applied for analyzing the results.Results Coaptation line of anterior and posterior leaflets was almost same in normal subjects.With increasing of mitral regurgitation,a tendency to prolong in LCA3dlf and LCP3dlf were observed in IMR (P ＜0.05).Compared to that in mild and moderate IMR groups,besides A3DTANT and A3DTPOST,LCA3dlf and LCP3dlf were also increased significantly in severe IMR group (P ＜0.05).LCP3dlf was an independent correlation factor of IMR by Logistic regression analysis.The sensitivity was 73.3％ and the specificity was 94.7％ when LCP3dlf≥32 mm was regarded as cut-off point,and the area under the ROC curve was 0.949 (0.900～0.999).Conclusions Abnormal coaptation of anterior and posterior leaflets of mitral valve might be one of main cause of IMR.Involution structure of mitral valve before surgery is helpful for surgeon to select an optical surgical procedure and evaluate effects of treatment in patients with IMR.

Objective To investigate the voiding patterns of term and preterm newborns and whether voiding in term and preterm neonates was accompanied by any cortical arousal. Methods Between May 2013 and September 2013,64 hospitalized newborns at Neonatal Intensive Cave Unit in the Frist Affiliated Hospital of Zhengzhou University were recruited in this study. In these patients,31 cases were term newborns(20 male,11 female)and 33 cases were preterm newborns(19 male,14 female). The term and preterm newborns gestational ages at birth were(38. 2 ± 1. 2) weeks and(32. 1 ± 1. 6)weeks,weighted(3. 3 ± 0. 4)kg and(1. 7 ± 0. 3)kg,respectively and postnatal ages at study were[4 - 16(10. 5 ± 3. 6)]days and[4 - 16(11. 2 ± 3. 1)]days. The voiding volume(VV),post - void residual volumes(PRV),body movement rate and voiding frequency(VF)in 4 hours as well as the volume of milk and liquid fed at the same time frame were recorded and analyzed,retrospectively. At the same time electrocardiogram(ECG)and electroencephalogram(EEG)were recorded. The changes of heart rate(HR),EEG frequency,respiratory frequency (RF)during the 5 s period and 30 s before and after voiding onset were compared respectively. For cortical arousal definition the recommendations of the International Pediatric Work Group on Arousals(2005)were used. Results A total of 184 times of voiding were recorded. In preterm newborns,the VV and body movements rate were significantly lower compared with the term newborns[(21. 8 ± 7. 9)mL and(41 ± 21)% vs(26. 4 ± 8. 7)mL and(62 ± 19)% , t = 3. 75,4. 20,all P ﹤ 0. 05]. However,the VF and PRV were significantly higher in preterm newborns[(1. 7 ± 0. 9) mL and(3. 2 ± 1. 1)times vs(1. 2 ± 0. 7)mL and(2. 6 ± 0. 9)times,t = 2. 47,2. 38,all P ﹤ 0. 05]. Bladder voiding in these infants happened only during QS. In term newborns,HR frequency was higher during the 5 s interval before and after voiding onset when compared with the 30 s period before voiding onset[(152 ± 6)times/ min and(152 ± 5) times/ min vs(147 ± 6)times/ min,t = 5. 30,5. 76,all P ﹤ 0. 05]and the EEG frequency[(2. 6 ± 0. 1)Hz and (2. 6 ± 0. 1)Hz vs(1. 5 ± 0. 1)Hz,t = 70. 0,70. 0,all P ﹤ 0. 05]. While the HR and EEG frequency of preterm neo-nate was not changed before and after bladder voiding onset. The RF of both term and preterm neonates were not changed before and after bladder voiding onset. Conclusions The voiding patterns between term and preterm were sig-nificantly different and cortical arousal was found only in term neonates,which indicate the term newborns have better mature bladder function and development of nervous system.

Objective To evaluate the value of high-frequency ultrasound in diagnosing the early reduced function of mice and to make sure the impact of aldosterone in cardiac remodeling after myocardial infarction.Methods Twenty aldosterone silence mice were selected as the experimental group and 20 healthy wild-type mice as the control.Animal models of acute myocardial infarction (AMI) were established by the method of the left anterior descending artery ligation.Cardiac function was measured by highfrequency echocardiography before and 2 weeks,4 weeks,6 weeks after AMI.Produce biopsy and Masson staining in both the experimental and the control groups were made post 6 weeks after AMI.Results ①Left ventricular long axis view and various short-axis views of mice could be clearly displayed by high-frequency echocardiography,and accurate measurements of the cardiac function could be obtained.② Compared with that in the control,left ventricular ejection fraction progressed more gradually in the experimental group than the control group (35.81 ± 2.88 vs 29.10 ± 4.50 at 6 weeks after AMI,P ＜0.05).Conclusions Blocked aldosterone may play a positive effect in reducing the myocardial injury.
