Objective To observe the change of renal function and cell apoptosis after injecting SB203580 before and after reperfusion, and investigate the protective role of p38 MAPK inhibitor SB203580 for ischemic/reperfused kidney in rats. Methods p38 MAPK inhibitor SB203580 was injected by tail vein into rats with ischemic kidney before and after reperfusion. The plasma levels of creatine and BUN were measured at various time points. The apoptotic rate in the renal tissue at various time points was determined using TUNEL. Results Administering SB203580 before reperfusion could decrease renal cell apoptotic rate, and renal function damage. Administering SB203580 after reperfusion had not obvious effect on the renal function and cell apoptosis. Conclusion Administering p38 MAPK inhibitor before reperfusion can attenuate post-ischemic renal fuction damage and cell apoptosis.

Objective:To investigate the chronic effect of topiramate on spatial learning and memory to young rats. Methods:P28 KA-induced rats were used. After 8-week treatment of topiramate, spontaneous recurrent seizures were recorded; Spatial learning and memory ability was evaluated by Morris water maze. Results: TPM-treated rats had significantly fewer(3.50?3.84) spontaneous recurrent seizures than rats without TPM treatment(7.36?3.75). On the first day of Morris water maze, they also had statistically longer latency to the platform(590.6?230.9 s) than those from the group without TPM treatment (422.6?122.3 s), but no latency differences were found in the following three days. TPM had no effect on water maze performance to rats without KA induction. After three days of interval, no differences were found in all groups under the same experimental situation.Conclusion:For developing rat brain, TPM has no impairment on the ability of long-term memory and information retrieval meanwhile its negative effect on spatial learning is temporary.

Objective To study the dynamic changes and potential impacts on the voice in postoperative pa-tients with different types of thyroid operation.Methods A total of 48 cases thyroidectomy,34 with thyroid isth-mus and lobectomy and 4 with total thyroidectomy,and 19 cases neck operation were included in this study for the examinations of electric laryngoscope,and acoustic voice analysis preoperative and postoperative,respectively.The characteristics of the acoustic parameters were analyzed.Results Vocal cord paralysis and cricothyroid joint disloca-tion in all the patients before and after operation were not observed.For male patients in the experimental group, postoperative parameter values of F0TD were higher than the day before surgery and 30 days after thyroidectomy. The difference was statistically significant (P <0.05 ).In female patients,postoperative parameter values of F0 were lower than the day before surgery and 2nd,7th,and30th day after thyroidectomy.Postoperative parameter values of Jitter for 30th day were lower than 1st day after the operation.The postoperative parameter values of F0TD for 1st,2nd,3rd,and 7th day were higher than the day before thyroidectomy.The parameter value of F0TD was lower than 1st day after surgery,and the postoperative parameter value of HNR for 30th day was lower than 3rd day after the thyroidectomy.The difference was statistically significant (P <0.05 ).Compared to the control group,there were no significantly differences in male patients of experimental group before and after the surgery(P >0.05).The parameter values of F0 in famale patients before the thyroidectomy,the 1st,2nd,3rd,7th day after the surgery and the parameter value of Jitter,Shimmer,HNR for 1st day after the operation were significantly dif-ferent(P <0.05).There were no significant differences in all parameter value of 30 days after thyoidectomy(P >0. 05).Conclusion Voice parameter values alter in a way after thyroid surgery without apparent recurrent laryngeal nerve injury,especially in the female patients.The improvement of voice acoustic parameters can be observed on the 30th day after operation.

Objective To investigate the influence of three kinds of different Ca~(2+) concentration of dialysate on serum calcium,calcium-phosphorus product,serum PTH and CRP in maintenance hemodialysis patients.Methods 45 patients of maintenance hemodialysis with ages ≥18 years were selected.They were divided randomly three groups,and be given three different kinds of Ca~(2+) concentration of dialysate to carry out hemodialysis with 3 months.Then the patients' variation of blood pressure and whether there were low calcium spasm or ostealgia were abserved during hemodialysis whole range.In addition,changes of their serum calcium、phosphorus、iPTH and CRP at pretherapy and three months after reatment were also detected.Results After three months of hemodialysis,serum iPTH in patients with low Ca~(2+) concentration dialysate increased obviously,and the serum CRP decreased significantly(P0.05),and serum CRP increase notably(P

Objective To study the growth rhythm of height, diameter at ground and the distribution of biomass of annual seedlings of Glycyrrhiza uralensis. Methods Dynamic measurings were carried out after sowing to determine the indexes including the growth quantity and biomass of overground and underground part of annual seedlings of G. uralensis. Results The growing period can be divided into four stages: the emergence phase, initiation phase, prosperous phase, and late phase. The growth quantity during the prosperity period accounted to 63.3% and 50.2% of biomass of the whole year. The growth rate of root was much higher than that of the stem and leaf. The accumulating rate of biomass is the highest during the period of the July 20th to September 20th. The biomass distribution ratio of root, stem, and leaf was 49.02∶17.75∶33.23, and the biomass ratio of underground part to overground part was 0.96. According to regression analysis, the height and diameter at ground were liner correlation with underground biomass and total biomass was individually larger than that of two biomasses of diameter at ground. Conclusion The growth pattern of the height and diameter at ground is accordance with S curve and can be simulated with Logistic equation. The height and diameter at ground is linearly correlation with the underground biomass and total biomass.

Objective Effect of provenance on seed biological characteristics and seedling growth in Glycyrrhiza uralensis was studied to indicate the important role of provenance in standardization production of traditional Chinese medicinal materials.Methods Indexes such as 1 000-seed weight,water content,seed capsule penetration,germination percentage,and germination potency of the seeds from various resources were determined by general ways.Growth indexes of young seedling and one-year seedling were determined.Results Between Shanghaimiao provenance and Bayinwusu provenance,1 000-seed weight of G.uralensis in Shanghaimiao was bigger,which was 12.3 mg for the former and 11.7 mg for the latter;water penetration of seed capsule was stronger in Bayinwusu and conductance rate was twice as much as it in Shanghaimiao.Shanghaimiao seed bearing storage and seed vigor were stronger and hard seed rate was higher.Germination percentage and germination potency of untreated seed in Bayinwusu was higher than that of Shanghaimiao,but lower after treatment.Germination percentage and germination potency of smaller seeds was the highest between the two different provenances in both the untreated and treated seeds.In growth indexes of two provenances,young seedling got a significant and the most significant difference.Growth index in Shanghaimiao was higher a little,which didn't get to an obvious level.Conclusion The provenances have an effect on physical characteristics,seed capsule penetration,and germination properties;provenance and seed size have an obvious effect on young seedling growth but have not any effect on one-year seedling growth and biomass.

Objective To valuate the left ventricular function and myocardial fibrosis using Dopple tissue imaging(DTI) and integrated backscatter(IBS) in diabetic cardiomyopathy(DCM) rats. Methods Diabetes mellitus(DM) in healthy male SD rats was induced by single injection of streptozotocin (STZ,Sigma) into intraperitoneal at a dose of 65mg/kg body weight. Left ventricular fractional shortening (LVFS),ratio of peak early to late diastolic mitral inflow velocity(E/A) by color Doppler flow imaging-pulsed wave (CDFI-PW), ratio of peak early to late diastolic mitral annulus velocity (Ea/Aa) by DTI,myocardial calibrated IBS (IB%), cyclic variation of IBS(CVIB) by IBS, were determined in rats of 4,12 and 24 weeks after DM was induced. Heart weight index(HWI), Masson's trichrome staining, expression of connective tissue growth factor(CTGF) and activity of sarcoplasmic reticulum Ca2+ -ATPase(SERCA2a) in heart were measured, while the age-matched health rats served as control group. Results ① Diastolic dysfunction of left ventricular was found in diabetic rats detected by CDFI-PW(E/A<1) at the 4th week,and developed gradually. Pseudonormal filling(E/A>1) was found in major diabetic rats at the 24th week,which could be identified by DTI(Ea/Aa<1). The IB% of left ventricular posterior wall was significantly higher in diabetic rats than those in the control group( P<0.05), but the CVIB of the 24th week diabetic rats was lower(P<0.05). The LVFS had no great alteration in six groups(P>0.05).②Compared with the control group, the activity of SERCA2a was reduced, while HWI, collagen volume fraction(CVF),perivascular collagen area(PVCA) and the expression of connective tissue growth factor(CTGF) protein in heart were increased in diabetic rats (P<0.05), and correlation between IB% and HWI, CVF, PVCA,CTGF was significant (P<0.05). Conclusions DTI and IBS can assess early left ventrieular diastolic function and fibrosis of diabetic cardiomypathy in STZ-induced diabetic rats. DTI echoeardiography can identify "pseudonormal" mitral inflow patterns. DCM may be relatived with overexpression of CTGF and decreasion of SERCA2a activity.
