BACKGROUND: Hippocampal formation of brain, a cerebral area related with learning and memory, is closely related to spatial cognitive activity.Peroxidative stress following the onset of cerebral ischemia can induce DNA injury in hippocampal 'area and dentate gyrus, the fall of the ability of DNA plerosis and correspondingly a decline in the function of learning and memory.OBJECTIVE: To investigate the effect of hongjingtian on the expression of nucleic acid of hippocampal area and dentate gyrus, the learning and memory area of rats with complete cerebral ischemia-reperfusion injury.DESIGN: Randomized controlled study.SETTING: Central Laboratory of Armed Police Medical College.PARTICIPANTS: The experiment was completed at the Central Laboratory of Armed Police Medical College from April 2002 to April 2004. Totally 60 Wistar male rats were selected and divided randomly into 5 groups Model group: Rats were perfused daily with distilled water of a volume the perfused daily with distilled water of a volume the same as that in medication group.METHODS: Rats in each group were perfused incessantly for 7 days.Modified Pulsinelli-4 vessel blocking method was used to reproduce the rat model of acute complete cerebral ischemia-reperfusion. Rats in sham-operation group were not treated with the operation of burning vertebral artery and clipping common carotid artery. The changes of DNA and RNA expressions in cerebral hippocampal area and dentate gyrus were observed with acridine orange staining method after model establishment.MAIN OUTCOME MEASURES: Expression of DNA and RNA in cerebral hippocampal area and dentate gyrus of rats in each group.RESULTS: All 60 rats entered the final analysis. DNA and RNA in shamoperation group distributed evenly, border of fluorescent reflex was legible and response intensity was strong. Border of DNA and RNA fluorescent reflex was illegible and response intensity was obviously weak in model ly, border of fluorescent reflex was legible and response intensity was group was not of obvious difference as compared with that in model group.CONCLUSION: The illegibility of DNA and RNA fluorescent response in operation group is related with the breakage of DNA chain induced by oxidative stress during cerebral ischemia-reperfusion injury. Border of DNA and RNA fluorescent reflex in hippocampal area and dentate gyrus is legihibit the breakage of DNA chain induced by oxidative stress and protect learning and memory function in hippocampal area and dentate gyrus of rats with complete cerebral ischemia-reperfusion.

OBJECTIVE： To establish a method for content determination of indapamide （IDP）-β-cyclodextrin （β-CD） inclusion compound， optimize the preparation technology， carry out phase identification and in vivo release study of it. METHODS： UV spectrophotometry was used to determine the content of IDP in IDP-β-CD inclusion compound. IDP-β-CD inclusion compound was prepared by the solution-stirring method and the preparation technology was optimized by the orthogonal experiment using inclusion rate as index. The inclusion rate and drug-loading rate were compared between different drying methods. Phase identification of IDP-β-CD inclusion compound was verified by IR and DSC. The cumulative release rate of inclusion compound was tested by in vitro experiment. RESULTS： The linear range of concentration of IDP was 2.0-14.0 μg/mL （r＝0.999 7）. The quantitative limit and detection limit were 0.204， 0.067 μg/mL， respectively. RSDs of precision， stability and repeatability tests were all less than 2％. The recoveries range was 98.8％-101.8％（RSD＝1.10％，n＝6）. The optimum technology conditions were as follows the molar ratio of β-CD to IDP was 3 ∶ 1， the inclusion time was 3 h， and the stirring speed was 300 r/min. Average inclusion rate of IDP-β-CD inclusion compound was 72.81％. IR and DSC analysis showed that IDP and β-CD formed inclusion compound through physical interaction. After spray drying， the inclusion rate and drug-loading rate of IDP-β-CD inclusion compound were （60.96±0.25）％ and （4.18±0.12）％. After freeze-drying， the inclusion rate and drug-loading rate of IDP-β-CD inclusion compound were （77.31±0.51）％ and （5.31±0.27）％. Accumulative release rates of IDP， IDP-β-CD inclusion compound （by freeze-drying and spray drying） were 37.2％， 42.5％ and 81.9％ within 12 h， respectively. Compared with IDP raw material， accumulative release rate of IDP-β-CD inclusion compound increased significantly after spray drying. CONCLUSIONS： Established method is simple and accurate. The optimal preparation technology of inclusion compound is stable and feasible. IDP-β-CD inclusion compound is prepared successfully. The inclusion compound prepared by spray drying shows higher release rate.

The objective was to investigate the effect of kinsenoside (Kin) treatments on macrophage polarity and evaluate the resulting protection of chondrocytes to attenuate osteoarthritis (OA) progression. RAW264.7 macrophages were polarized to M1/M2 subtypes then administered with different concentrations of Kin. The polarization transitions were evaluated with quantitative real-time polymerase chain reaction (qRT-PCR), confocal observation and flow cytometry analysis. The mechanism of Kin repolarizing M1 macrophages was evaluated by Western blot. Further, macrophage conditioned medium (CM) and IL-1 were administered to chondrocytes. Micro-CT scanning and histological observations were conducted on anterior cruciate ligament transection (ACLT) mice with or without Kin treatment. We found that Kin repolarized M1 macrophages to the M2 phenotype. Mechanistically, Kin inhibited the phosphorylation of IB, which further reduced the downstream phosphorylation of P65 in nuclear factor-B (NF-B) signaling. Moreover, Kin inhibited mitogen-activated protein kinases (MAPK) signaling molecules p-JNK, p-ERK and p-P38. Additionally, Kin attenuated macrophage CM and IL-1-induced chondrocyte damage. , Kin reduced the infiltration of M1 macrophages, promoted M2 macrophages in the synovium, inhibited subchondral bone destruction and reduced articular cartilage damage induced by ACLT. All the results indicated that Kin is an effective therapeutic candidate for OA treatment.
