Conclusion COX-2 was involved in occurrance and development process of lung cancer.

It has been demonstrated by our previous research that 4-(2-acetoxybenzoylamino) butyramide derivatives exhibited good antiepileptic activities. In this paper, to explore the SAR and improve the antiepileptic activities of these derivatives, a series of novel 4-(2-acetoxybenzoylamino) butyramide heterocyclic compounds (5a-5n) were synthesized and biologically evaluated. Their structures were confirmed by 1H MNR, ESI-MS and elemental analysis. Pharmacological test in vivo showed that target compounds (5f, 5i-5n) displayed strong antiepileptic activities on 4-AP induced epilepsy in mice with ED50 values ranging from 0.3137 to 0.3604 mmol x kg(-1).

Objective To analyze and study the implication of dynamic changes in plasma CD62P among patients with obstructive jaundice and cholecystolithiasis.Methods A total of 58 patients diagnosed with choledocholithiasis and jaundice were included in the obstructive jaundice group,and 50 patients were in the cholecystolithiasis group.Peripheral venous blood was collected on preoperative day 3,on opera-tive day,and on postoperative days 3,6,9,12,15,18,and 21 in two groups,and the concentrations of plasma CD62P were measured by ELISA.Comparison of continuous data between the two groups was made by t test.Results The concentrations of plasma CD62P from preop-erative day 3 to postoperative day 18 were significantly higher in the obstructive jaundice group than in the cholecystolithiasis group (P<0.01 across all time points).In the cholecystolithiasis group,the concentrations of plasma CD62P significantly increased on operative day, and the increase continued and reached the peak on postoperative day 3,then followed by a decrease down to the preoperative level on post-operative day 9.In the obstructive jaundice group,the concentrations of plasma CD62P reached the peak on postoperative day 9,followed by a gradual decrease down to the preoperative level on postoperative day 18 and to an even lower level (preoperative level of patients with cho-lecystolithiasis)on postoperative day 21.Conclusion Extrahepatic biliary obstruction may lead to endothelial cell injury and platelet acti-vation,the condition of which is improved with the relief of obstruction.The surgery for obstructive jaundice may lead to much more endothe-lial cell injury and higher platelet activation than that for cholecystolithiasis.

BACKGROUND: In recent years, percutaneous kyphoplasty (PKP) has been widely used in the treatment of osteoporotic vertebral compression fractures, but there are still some complications, such as bone cement leakage and re-fractures, and a lack of follow-up treatment.OBJECTIVE: To investigate the effect of PKP with low-dose bone cement in combination with zoledronic acid on bone mineral density (BMD), vertebral height and low back pain after osteoporotic vertebral compression fractures.METHODS: Eighty patients with osteoporotic vertebral compression fractures were equally randomized into test group (treated with PKP with low-dose bone cement in combination with zoledronic acid) and control group (treated with PKP with conventional bone cement). Visual analog scale score, vertebral height, and Cobb angle were detected before, at 3 days after treatment and at the final follow-up visit. BMD and re-fracture incidence were reviewed 1 year after treatment.RESULTS AND CONCLUSION: Visual analog scale scores, vertebral height, and Cobb angle were significantly improved in both groups at 3 days after treatment and at the final follow-up visit (P < 0.05); however, there was no statistical difference between the test and control groups. One year after treatment, the BMD value was significantly increased in the test group (P < 0.05), but showed no change in the control group as compared with the pretreatment.Postoperatively adjacent vertebral fractures were found in one case of the test group, and five cases in five cases of the control group. These findings indicate that PKP with low-dose bone cement in combination of zoledronic acid can effectively relieve pain symptoms, restore the height of the vertebral body, significantly increase BMD value and reduce the incidence of adjacent vertebral fractures in patients with osteoporotic vertebral compression fractures.

Objective To study the effect of apelin-13 on myosin light chain (MLC)phosphorylation in vascular smooth muscle cells under the condition that the permeability of endothelial layer is changed by ADMA.Methods Human umbilical vein endothelial cell (HUVECs) were cultured in bottom of upper well of Transwell system to establish the endothelial monolayer barrier.The cells were cultured normally or incubated with ADMA.Some FITC-apelin-13was added to the upper well.After a period of leakage time,the amount of FITC-apelin-13 in the lower well was measured to evaluate Pa value,which reflected the permeability of endothelial monolayer. Thechangesofcytoskeletonandintercellularjunctionwereobservedby immunofluorescence.Subsequently,Transwell dishes were used to establish a co-culture system with HUVECs in the upper well and human umbilical vein smooth muscle cells(HUVSMCs) in the lower well.There were four groups: blank control group; ADMA group,stimulated by ADMA only;apelin group,apelin-13 used only; ADMA+apelin group,apelin-13 used after HUVECs stimulated by ADMA.Immunofluorescence and Western blotting were used to detect phosphorylation of MLC in HUVSMCs.Results ADMA induced changes of cytoskeleton and intercellular junction and increased endothelial permeability of apelin-13.The percentage of Pa between ADMA-stimulated and control groups varied during the period of apelin-13 pass and peaked at 20 minutes,which was significantly higher than that at 0 minutes [(176.3±9.2)％ vs (100.3±1.5)％,P＜0.05].In the co-culture system,Western blotting showed that p-MLC expression in ADMA +apelin group was significantly higher than that in apelin group(P＜0.05).In ADMA group,a few p-MLC expression was found also.Phosphorylation of MLC in above 3 groups was significantly higher as compared to blank control group(P＜0.05).Conclusions ADMA can increase endothelial permeability of apelin-13 by inducing changes of cytoskeleton and intercellular junction.Apelin-13 passes through the damaged endothelial barrier and directly acts on vascular smooth muscle cells to elevate phosphorylation of MLC,which may play an important role in hypertension of uremic patients.

To explore new agents of gamma-aminobutyric acid (GABA) derivatives with more potent antiepileptic activity, a series of 4-(2-acetoxybenzoylamino) butyramide derivatives were designed and synthesized. All of the novel compounds (5a-51) were synthesized from GABA as starting material, and their structures were confirmed with IR, 1H NMR, EI-MS and elemental analysis. Preliminary pharmacological test in vitro showed that all target compounds displayed strong antiepileptic activities and were worth for further study. The structure-activity relationship of 4-(2-acetoxybenzoylamino) butyramide derivatives was also discussed preliminarily.

Objective To evaluate the effects on the mineral bone disorder using different calcium concentration citrate-based dialysate in maintenance hemodialysis (MHD) patients.To compare the concentrations of intact parathyroid hormone(PTH) with biointact PTH(1-84) in these patients.Methods Citrate dialysate with different calcium concentration (DCa 1.75,DCa 1.5,DCa 1.25 mmol/L)were used in turn in 15 stable MHD patients each week.Serum tCa and iCa were measured by automatic biochemistry analyzer.The concentrations of iPTH and bio-iPTH were compared.Results (1) The patients treated with DCa 1.75 citrate dialysate had increased serum iCa and tCa after dialysis,and PTH did not change significantly as compared to those findings before the dialysis.With the DCa 1.5 citrate dialysate,serum iCa and tCa were kept stable and PTH level was increased.With DCa 1.25 citrate dialysate,serum iCa and tCa decreased significantly and PTH decreased.(2)iPTH and bioPTH had excellent correlations.Variation of bio-iPTH was more correlated with the changes of calcium than iPTH.Conclusions Serum levels of iPTH,tCa and iCa can be kept stable in MHD patients treated with DCa 1.75 ～ 1.5 citrate dialysate.Bio-iPTH is a more sensitive marker for mineral bone disease than iPTH.

The target value of intact parathyroid hormone (iPTH) in main international guidelines is not consistent completely.Furthermore,the evidence levels of clinical studies these guidelines based on are generally low and most of them are based on observational studies.Some studies even showed that there was no association between iPTH level and clinical outcomes.This review focuses on the following three points for reassessing iPTH target value: comparison of iPTH target value in main international guidelines,the difference of iPTH target value in large clinical studies and reasons for the difference.

Objective To study the effect of long-term salmon calcitonin on bone mineral density (BMD), bone metabolism biochemical indicators and subjective score of bone pain in maintenance hemedialysis (MHD) patients with osteopenia. Methods Thirty-four MHD patients diagnosed as osteopenia by dual-energy X-ray absorptiometry (DXEA) were enrolled in this study. All the patients were treated with hypodermic injection of salmon calcitonin (50 U, thrice a week) for 12 months. The detecting parameters were as follows: BMD with DEXA in lumbar spine (L1-L4), femoral neck, troch, inter, and Ward's triangle before and after the study;serum bone metabolism biochemical indicators before and 6 and 12 months after the study;subjective scores of bone pain before and 1, 6, and 12 months after the study. Results Thirty-two patients were followed-up successfully. As compared to BMD parameters before study, the total T-score (-1.98± 2.20 vs 1.26±1.88, P=0.009) and total Z-score (-0.90±2.15 vs 0.08±2.05, P=0.002) of lumbar spine, the total T-score (-1.72±1.53 vs 1.06±1.58, P=0.016) and totle Z-score (-0.66±0.80 vs 0.08±1.08, P=0.029) of hip, the T-score of L3 (-2.02±2.51 vs 1.24±2.02, P=0.033), the Z-score of L2 (-0.44±1.82 vs 0.06±1.63, P=0.016), the Z-score of femoral troch (-0.65±1.11 vs 0.48±1.12, P=0.034) and the Z-score of inter (-0.58±0.94 vs 0.02±1.12, P=0.006) were increased significantly after study. But there were no significant differences in other examined regions and serum biochemical parameters. The subjective scores of bone pain were decreased rapidly for 41.7% after 1 month (P<0.01) and 76.6% after 6 months (P<0.01). The subjective score of bone pain after 12 months was similar to 6 months. The side effects of salmon calcitonin included nausea and vomitting in 5 cases (14.71%, 5/34), dizziness, blushing and flustered in 1 case respectively (3.13%,1/32). Conclusions Long-term hypodermic injection of salmon calcitonin can improve BMD and bone pain for MHD patients with osteopenia but has no significant effect on serum bone metabolism biochemical indicators. Salmon calcitonin is safe for MHD patients with seldom side effects, such as nausea and vomitting.
