To observe the levels of platelet-activating factor (PAF), interleukin-6 (IL-6) and IL-17 in peripheral blood of rats with adjuvant arthritis (AA), and the effects of Xinfeng Capsule (XFC), a compound traditional Chinese herbal medicine.

OBJECTIVE: To observe the effects of Xinfeng Capsule (XFC), a compound Chinese herbal medicine, on behaviors and myocardial ultrastructure in adjuvant arthritis (AA) rats. METHODS: Fifty-five rats were randomly divided into normal control group, untreated group, methotrexate (MTX) group, Tripterygium wilfordii glycosides tablet (TGT) group and XFC group. There were 11 rats in each group. Except for those in the normal control group, the rats in the other groups were all intracutaneously given 0.1 ml Freund's complete adjuvant in the right hind limb. Changes of behaviors and myocardial ultrastructure of the rats in different groups were observed. RESULTS: Voix pedis' swelling and arthritis index in XFC, MTX and TPT groups were all obviously improved as compared with the untreated group. After XFC treatment, the autonomic activities were obviously increased, number of errors in exercise period and test period were obviously decreased, step-down latency (SDL) was lengthened and escape latency (EL) was shortened. Overall structure of myocardial myofibril and the majority of cristae was intact in XFC group. The effects of XFC in improving the behaviors and myocardial ultrastructure were better than those of MTX and TPT. CONCLUSION: Changes of behaviour and myocardial ultrastructure of AA rats can be observed. XFC can improve the myocardial ultrastructure of AA rats as well as their behaviors.

Objective To observe effects of Xinfeng capsule (XFC) on platelet parameters,ultrastructure,p-selectin and therapeutic effect on rheumatoid arthritis (RA) patients in active phase.Methods Platelet parameters,p-selectin and reactive indexes of 60 RA patients in active phase were detected.RA patients were divided into XFC treated group (35 examples) and Zhengqing Fengtongning (ZQF) control group (25 examples) randomly.After a course of treatment,the therapeutic effect and changes of platelet parameters,p-selectin,reactive indexes of two groups were observed.Setting up a normal control (20 examples) and detecting above-mentioned indexes.Observing platelet ultrastructure of two examples with transmission electron microscope of per groups.Results Compared with normal control group,PLT,PCT,MPV,CD62P of RA patients in active phase was obviously increased.Platelet ultrastructure was obviously damaged.The excellence rate of XFC exceeded ZQF control group.After being treated,platelet ultrastructure of the two groups were obviously improved,and XFC group was better than ZQF group.Compared with ZQF group,PLT,PCT,CD62P were obviously decreased in XFC group.PLT,PCT were positively correlated with CD62P,IgG,ESR,CRP,RF,arthrpain,arthrocele.And PLT was positively correlated with arthrtenderness,morning stiffness time.Conclusion PLT and PCT of RA patients in active phase were increased,and have correlation with reactive indexes.It suggests that PLT,PCT can reflect reactiveness of RA as objective indexes.XFC can not only treat inflammation and delay the aggravation of RA patient by improving platelet ultrastructure.

We used 4 methods,such as ultrasonic crush(UC),ultrasonic rinse(UR),whorl surge(WS)and rubbing(RU),to isolate epiphytic bacteria from red alga Gracilaria lemaneiformis.Then,we counted bacteria numbers,detected bacterial species,observed bacterial configuration and characteristic of cell wall.Compared with these methods and with different treatments in one method,the results were drawn:the UR and RU were inferior in all methods to isolate bacterial numbers and species,the UC and WS were better,especially,the treatment 30W 30s of UC was the best in experiment,which isolated 12 of 16 bacterial species,and got 1.75 10~6 cells per gram wet weight G.lemaneiformis.

Objective To investigate the effect of vaccum-assisted closure(VAC)on the expression of C-ski and Smad3 in the human wound margin tissue and to explore their significance in triggering the wound healing.MethodsFourteen patients,9 males and 5 females with chronic wound admitted in our department from April 2007 to April 2009 were enrolled into the study after signed an informed consent,and the full-thickness skin defects were collected before treatment,and 1,4 or 7 d after treatment.Immunohistochemistry(IHC)was carried out to detect the expressions of C-ski and Smad3,and RT-PCR was used to determine their mRNA expressions of C-ski and Smad3.ResultsIHC results showed that there existed little C-ski in the wound margin tissue before treatment,and after treatment,it were gradually increased.Compared with before treatment group,the differences in 4 and 7 d after treatment were markedly significant(P0.05).Compared with above groups,the differences in 4 and 7 d after treatment groups were markedly significant(P

Aim Toinvestigatetheroleofbrain-de-rived neurotrophic factor(BDNF)-tyrosine receptor ki-nase B (trkB ) signaling pathway in the therapeutic effects of ketamine on diabetic neuropathic pain.Meth-ods Forty-eightWistarrats,aged3months,weighing 200~250 g,were equally randomized into 4 groups(n=12 ):control group (C group ), saline group (S group),ketamine group (K group)and ketamine +ANA-12 group (KA group ).Rats in S,K and KA groups were intraperitoneally injected with a single of streptozotocin(STZ)65 mg·kg-1 to construct diabetic neuropathic pain model.After twenty-eight days,rats in S,K and KA groups were intraperitoneally injected with saline, ketamine 10 mg·kg-1 and ketamine 10 mg·kg-1 +ANA-12 0. 5 mg·kg-1 for consecutive 7 days, respectively. On the 8th day, mechanical withdrawal threshold(MWT)of rats was measured.Af-ter that,the rats were immediately sacrificed,and dor-sal ganglion of lumbar spine and prefrontal cortex (PFC)were harvested for measuring BDNF,p-trkB/trkB,synaptophysin and spine density by Western blot andglogistaining.Results ComparedwithCgroup, rats in S group significantly decreased MWT,BDNF, p-trkB/trkB,synaptophysin and spine density in dorsal ganglion and PFC (P <0. 05 ).Compared with S group,rats in K group showed a significant increase of MWT,BDNF,p-trkB/trkB,synaptophysin and spine density in the all observed regions(P<0. 05 ).On the contrary,rats in KA group showed a significant de-crease of MWT and BDNF,p-trkB/trkB,synaptophys-in and spine density as compared with K group in all regions(P<0. 05 ).Furthermore,BDNF was positive-ly correlated with spine density in all regions (P <0.05).Conclusion BDNF-trkBsignalingpathway mediates ketamine-induced therapeutic effects in dia-betic neuropathic pain.

Background In the past few decades,the balance of Th1/Th2 is often used to explain the immune mechanisms of fungal infection and fungal disease.More recently,a novel subset of CD4+ effector Th cells has been found to participate in anti-fungal infection response.However,whether Th17 is involved in the immune response in fungal keratitis is unclear up to now.Objective Present study was to investigate the expression change of Th17 type cytokine and its specific transcription factor,retinoid-related orphan nuclear receptor gamma t (RORγt),in the cornea of Fusarium solani keratitis.Methods Ninety-six clean BALB/c mice were divided into Fusarium solani keratitis model group and control group by randomized digital table.Fusarium solani keratitis models were established by epikeratophakia-assisted corneal epithelial erasion and interlayerly injection of 5 μl (1 × 106 CFU/ml) Fusarium solani solution in the right eyes,and the equal volume of PBS was injected in the same way in the control group.10％ KOH wet film was used to examine the fungal hyphea and funga strain was identified by inoculation.The corneas were examined under the slit lamp microscope 1 day,3,5,7 days after modeling and the inflammatory response was scored based on the criteria of Wu and Hu.The histopathological examination of corneas was performed in the time points above.Real time fluorescence quantitative PCR was used to detect the expression levels of interleukin-17 (IL-17) mRNA and RORγt mRNA in the corneas.The expression of IL-17 protein in the corneas was detected by ELISA.The use and raise of the mice followed the Statement of Association for Research in Vision and Ophthalmology.Results The inflammatory scores were 3.2±0.8,6.6± 1.1,9.4± 1.1 and 6.8±0.8 in 1 day,3,5,7 days after modeling,showing a significant difference among them (F =89.786,P =0.010).The inflammatory scores were higher in the third and seventh day than that in the first day (P＜0.05),but they were significantly lower than that in the fifth day (P＜0.05).The infiltration of inflammatory cells showed a coincident tendency with the score.The expressing levels of IL-17 mRNA (2-ΔΔCt) in the corneas were 4.12±0.73,20.72±1.81 and 14.16±1.88 in 3,5,7 days after modeling,with statistically significant differences in comparison with those in the control group (P＜0.01),and the expression level was significantly higher in the fifth day than those in the first,third and seventh day in the model group(P＜0.01).The expression levels of IL-17 protein (ng/g) were significantly increased 1 day,3,5,7 days in the model group compared with the control group (P＜0.01).A similar change was found in the expression of RORγt mRNA to that of IL-17 mRNA.Conclusions Expressions of IL-17 and its transcription factor RORγt upregulate in the fungal keratitis and has an association with inflammatory degree,which suggests that Th17 subset may play an important role in the immune responses of fungal keratitis.

Objective To discuss the femoral neck anteversion(FNA) of developmental dislocation of the hip(DDH) and guide operation with visual and digitalized picture in the dimensional(3D) CT.Methods Ninety children with unilateral DDH were selected,and they were analyzed using 3D CT.Children whose FNA exceed 45 degree received the subtrochanter osteotomy with images from different direction,FNA of hip was measured respectively before and after operation and was measured in normal and abnormal hips respectively,FNA of hip received respectively statistical treatment.Ninety patients (90 hips) were followed up ranging from 3 months to 2 years with the mean of 13 months.Results In the group younger than 18 months,the FNA whose in normal hips was(19.40?3.512)degree,the FNA while(68.45?12.272)degree in dysplasia hips respectively,the FNA measured after operation was (20.45?2.940) degree;in the group elder than 6 years,there were significantly statistical differences,the FNA in normal hips was(19.44?3.561)degree,in dysplasia hips respectively was(73.49?12.678)degree,while the FNA measured after operation was(18.28?1.931)degree.Clinical assessment was performed according to Mckay′s classification.The results showed that the overall excellent or good rate was 95.6%.Conclusions 3D CT method is a new accurate and convenient and reduplicative method for measuring FNA.It will be more helpful for related operations when 3D images are considered.

APOBEC3 is a class of cytidine deaminase, which is considered as a new member of the innate immune system, and APOBEC3G belongs to this family. The research about APOBEC3G is a new direction of innate immune defense mechanism against virus. APOBEC3G has the restrictive activity on many viral replications, which deaminates dC to dU in the viral genome and then induces extensive hypermutation. APOBEC3G can also interrupt viral replication at several phases such as reverse transcription, replication, nucleocapsid and so on by non-deamination mechanisms. However, virus can encode viral proteins to counteract the restriction activity of APOBEC3G. Elucidation of the antagonistic interaction between APOBEC3G and the virus will be contributed to development of new antiviral drugs in the future.
