Objective To study the effect of hesperidin on the locomotor activity of mice with infective brain injury induced by li-popolysaccharide (LPS)in the dark field environment.Methods 45 ICR mice were randomly divided into 3 groups:Saline group, LPS group and LPS+Hesperidin group,15 mice in each group.The moving distance and the number of crossing line in the dark field were recorded using the ZH-ZFT locomotor activity video analysis system.ResultsThe LPS group had significantly shorter moving distance as well as lower frequency of the number of crossing line than those of the Saline group(P<0.05);compared with the LPS group,the Hesp group moved longer and crossed line more frequently,the differences between the two groups had statisti-cal significance (P<0.05).Conclusion Hesperidin could significantly improve the capacity for action in the dark field of mice with infective brain inj ury induced by LPS.

AIM: To observe the therapeutic effect of modified Bushen Huoxue granules (MBHG) on ovariec-tomized osteoporosis rats.METHODS: Female SD rats were randomly given sham operation (n =10) and ovariectomy, and then the model rats were further randomly divided into model group, MBHG treatment groups at doses of 200 mg/kg, 100 mg/kg and 50 mg/kg respectively, and positive control (estradiol valerate) group, with 10 rats in each group by intra-gastric administration for 12 weeks.The morphology, area, thickness, spacing and area percentage of trabecular bone in the rats were observed.The serum levels of calcium (Ca), phosphorus (P) and alkaline phosphatase (ALP) were mea-sured by automatic analyzer.Bone mineral density (BMD) was analyzed.Serum estradiol (E2 ), osteocalcin (BGP), os-teoprotegerin (OPG), receptor activator of nuclear factor-κB (RANK) and receptor activator of nuclear factor κB ligand (RANKL) levels were detected by ELISA.RESULTS: Compared with model group, trabecular bone significantly widened in all treatment groups with large number, and net-like structure restored partially.The thickness, area and area percenta-ges of trabecular bone in treatments groups were higher than those in model group,and trabecular spacing was less than that in model group (P <0.05).The serum Ca, P, E2 and OPG, and femoral BMD were significantly higher in treatment groups than those in model group, and the levels of ALP, BGP, RANK and RANKL were significantly lower than those in model group (P <0.01).CONCLUSION: MBHG has a significant therapeutic effect on ovariectomized osteoporosis rats. The mechanism may be related to the regulation of OPG and inhibition of RANKL secretion.

AIM: To investigate biological effect of endothelin-1 (ET-1) on differentiation of cardiomyogenic cells (CGCs) induced from rabbit bone mesenchymal stem cell (BMSCs) in vitro. METHODS: The BMSCs from shaft of femur of Japan rabbits were isolated and propagated for cell culture. Cultured BMSCs were randomly divided into six groups: Group Ⅰ: the control group (uninduced group); Group Ⅱ: the ET-1 group, added ET-1 (30 nmol/L) into culture medium; Group Ⅲ: 5-aza group, added 5-aza (10 ?mol/L) into culture medium; Group Ⅳ: 5-aza+ET-1 group, after inducing with 5-aza for 3 weeks, ET-1 was added into culture medium. This group was divided into three parts-Ⅳ 1、Ⅳ 2、Ⅳ 3, and separated to add 10、 30、 50 nmol/L ET-1. During the cell culture, growing and differentiation of BMSCs were observed. After inducing for 4 weeks, the differentiation rate and the diameter of cardiomyogenic cells were calculated; Western-blot was employed to analyze the expressions of GATA-4 protein and phosphorylation level. The expression of ?-MHC mRNA was assessed by RT-PCR. Immunohistochemistry staining of Troponin-I and ultrastructure observation of induced cardiomyogenic cells were also completed simultaneously. RESULTS: The cell diameters of CGCs in group Ⅳ 2 were enlarged significantly (P0.05). In group Ⅲ and Ⅳ 2 , the positive cells of cTroponin I staining were more, the expression of ?-MHC mRNA was significantly increased (P

Objective To study the dynamic changes of regional cerebral blood flow(rCBF) in hematoma, perihematoma and their enantiomorph in the contralateral hemisphere in the patients with acute intracerebral hemorrhage(ICH). Methods 15 patients of acute basal ganglia hemorrhage were divided into different groups according to the Chinese Stroke Scales, 10 patients were minor, the other 5 patients were moderate. 99mtechnetium-ethyl -cysteinate-dimer single-photon emission CT ( 99mTc-ECD SPECT) were performed within 3 days after onset of the disease and re-examined at 16 days. The method of region of interesting (ROI) was used to measure the uptake counts in the core of hematoma, frontal or parietal region around the lesion, the center of cerebellum and their enantiomorphs in the contralateral hemisphere, respectively,and to calculate the ratio of uptake counts.Results The uptake counts showed difference in the second time exam between perilesion and its enantiomorph in minor patients ( P0.05). The uptake counts of contralateral cerebellum were less than those of hemorrhage lateral cerebellum ( P

Methods:Fifty C57BL/Ksj-db/+m mice were randomly divided into 2 groups, db/db diabetic group and control group. The morphological changes of submandibular gland and the expression of PCNA were observed by using light microscope (LM) and immunohistochemistry. Results:Submandibular gland atrophy and the significant morphological changes in acini and ducts were observed in db/db diabetic mice. PCNA was expressed in submandibular gland in both diabetic mice and control mice.The percentage of PCNA positive cells was significantly decreased in diabetic mice than that in control(P

Objective To explore the relationship between osteopontin (OPN),its downstream product thrombin-cleaved osteopontin (NTOPN) and radiographic changes in osteoarthritis (OA).Methods The levels of OPN and NTOPN in serum and synovial fluid were tested by enzyme-linked immuno sorbent assay (ELISA) kit in 22 OA patients and 21 health controls.The correlation between the above parameters and clinical data such as radiology changes of OA patients was analyzed.Results The serum level of OPN in the OA group was positively correlated with C reactive protein (CRP) (r =0.574,P =0.005).The serum level of OPN in the OA group was slightly lower than that in the healthy control group [(1.8 ± 0.5) μg/L vs (1.7 ± 1.1) μg/L,P ＞ 0.05].Similarly,the serum level of NTOPN in the OA group was significantly higher than that in control group [(21.1 ± 11.7) μg/L vs (14.7 ± 3.6) μg/L,P ＜ 0.05].Meanwhile,serum NTOPN level in female patients was significantly higher than that in male patients [(23.2 ± 11.80) μg/L vs (11.1 ± 4.9) μg/L,P ＜ 0.05].In synovial fluid of OA group,the level of OPN was (7.75 ± 2.33) μg/L,NTOPN was (0.91 ± 0.49) μg/L and the ratio of NTOPN/OPN was 0.12 ± 0.08.The level of OPN of synovial fluid in the OA group was positively correlated with CRP (r =0.574,P =0.005).NTOPN-to-OPN ratio of synovial fluid in the OA group was positively correlated with Kellgren-Lawrence grade (r =0.535,P =0.022).Conclusions The serum level of OPN is correlated with severity of inflammation in the OA patients.Meanwhile,NTOPN-to-OPN ratio of synovial fluid is correlated with OA severity.As a downstream bioactive product of OPN,NTOPN may play an important role in OA pathogenesis.Whether these parameters can be used as predictors of joint lesion severity and inflammatory status is worth further study.
