Objective To study how polyclonal antibodies against ciliary neurotrophic factor (CNTF) reduce botulinum toxin-in- duced axonal sprouting and affect paralytic muscle.Design Experimental study.Participants 20 New Zealand rabbits.Methods In 10 rabbits randomly selected,left superior rectus were as control (Group 1),right superior rectus were injected with botulinum toxin A (BTXA) 2.5U (Group 3).At 14th day,bilateral superior recti were taken out under general anaesthesia.In the other 10 rabbits,left su- perior recti were injected equivalent physical saline (NS) as control (Group 2);right superior recti were injected with BTXA 2.5U,after 4 days,injected with 50?l polyclonal antibodies against CNTF at same site (Group 4).And at 14th day,bilateral superior recti were taken out for electron microscopy,dyed with acetylcholinesterase,argentums (Ag) to show nerve axonal sprout,and accounted and mea- sured with Leica microsystems.Main Outcome Measures The mean number of sprouts and the mean total length of sprouts,and the uhrastructure change of muscle by electron microscopy.Results In Group 1,the mean number of sprouts and the mean total length of sprouts were 5.75% and 10.53?m respectively;Group 2 were 6.11% and 11.16?m;Group 3 were 84.04% and 170.71?m;and Group 4 were 54.77% and 68.12?m.The differences were statistically significant (all P=0.000).Electron microscopy showed that after admin- istration BTXA alone (Group 3),muscle atrophied obviously,nerve myelin sheath increased,while the structure of nerve and muscle re- main invariable.The Group 4 showed that local myofilament disrupted and dissolved,degenerative myocytes necrotized and disintegrat- ed into fragments,which led to partial unreversible destroy.Conclusion Polyclonal anti-CNTF can reduce BTXA-induced axonal sprout- ing,lead to partial unreversible destroy of muscle,which may prolong the time of paralytic muscle resuming.It suggests that polyclonal anti-CNTF could prolong the duration of muscle paralyses induced by botulinum toxin.

ObjectiveTo investigate the role of the anti-podocyte antibody in the pathogenesis of membranous nephropathy(MN).Methods Thirty-six frozen section slice from biopsies of normal kidney were randomly divided into 3 groups:A,B and C groups(n=12,respectively),then,serum of MN and IgA nephropothy patients,and normal saline were added by drops to frozen section respectively,then the changes were observed by fluorescence microscope.Twenty-one male New Zealand white rabbits were feed with standard diet for 1 week,then were randomly divided into 3 groups:D,E,F groups (n=7,respectively),and injected with the serum of MN and IgA nephropathy,and normal saline respectively through ear-border vein.24-h urinary protein, serumalbumin, serumcreatinineweredetected. Atweek8afterinjection, the histopathological changes in kidney tissue of rabbits were observed by light microscope,electron microscope and immunofluorescence staining. Results Immunofluorescenee staining displayed IgG deposition in glomerular podocytes in group A,and there was no positive expression in other two groups.The quantitative measurement of 24-h urinary protein increased significantly after injection of MN serum (P＜0.01),meanwhile the serum albumin markedly decreased (P＜0.01).The inmnunofluorescence staining showed that IgG deposited in the glomerulus capillaries wall,which presented spherical particles.Light microscope revealed the thickening of GBM without nailing process formation.Electron microscope showed the podocyte foot processes,subepithelial dense deposits.Such pathological changes were not found in E group and F group.Conclusion There is anti-podocyte antibody in blood of MN patients,which may play a role in the pathogenesis of MN.

Objective To explore the impact of elective caesarean section and vaginal delivery on maternal pelvic floor dysfunction. Methods A total of 131 pregnant women from January 2014 to March 2015 in our hospital were divided into observation group which re-ceived elective caesarean section and control group which received vaginal delivery.All the maternal and neonatal clinical data were counted. The occurrence of pelvic floor dysfunction disease in postpartum women after 6 to 8 weeks was observed.The occurrence of vaginal wall pro-lapse,uterine prolapse,stress urinary incontinence (SUI)and maternal pelvic floor muscle damage between two groups were compared and analyzed.Results There were varying degrees anterior vaginal wall prolapse phenomenon occured on 31 cases in obervation group,the pro-lapse rate was 67.39%,compared with 92.94% of the control group,the difference was statistically significant (P <0.05).Observation group with 13 cases of descent vaginae posterior,the prolapse rate was only 28.26%,compared with 75.29% of the control group,the differ-ence was statistically significant (P <0.05 ).The maternal uterine prolapse rate of observation group was about 13.04%,compared with 35.29%(30 cases)of the control group,the difference was statistically significant (P <0.05).Observation group with 6 cases of maternal SUI, the probability is about 13.04%,compared with 29.41% of control group,the difference was statistically significant (P <0.05).There was no significant difference in deep and shallow maternal pelvic floor muscle between two groups(P >0.05).Conclusion To adopt elective cesar-ean section has a lower probabilities of postpartum pelvic floor dysfunction disease than that by vaginal delivery for maternal women,which is propitious to the recovery of pregnant women,while it has nothing to do with pelvic floor muscle damage.

AIM: To evaluate the correlation between in vitro release and in vivo absorption of aniracetam in conventional tablets and self-emulsifying drug delivery system (SEDDS), to investigate pharmacokinetics of aniracetam self-emulsifying drug delivery system and conventional tablets of aniracetam after oral administration to rats. METHODS: Dissolution behavior of these formulations was evaluated in vitro to assess the properties of dosage forms. And a new RP-HPLC method was developed for the in vivo quantitative determination of 4-p-anisamidobutyric acid (PABA), the active metabolite of aniracetam. To approach the in vitro-in vivo correlation, fraction absorbed in vivo (f) was calculated by Wagner-Nelson method, and then compared with in vitro released drug percentages (Q%). RESULTS: Aniracetam was released rapidly from SEDDS with 80%±4% of accumulation dissolution rate compared to that from conventional tablets at 15 min. The recovery of active metabolite of aniracetam was about 90%, and the intra-days and inter-day precision were within 4% and 6%, respectively. The AUC0-∞ value of aniracetam SEDDS was (11 168±2 395) ng·mL-1·h, which was about 3 folds greater than conventional tablets. The parameter MRT0-∞ of aniracetam SEDDS and conventional tablets were (2.7±0.6) h and (1.7±0.6) h, respectively, and the difference was statistically significant(P<0.05). The linear equation of in vitro-in vivo correlation for conventional tablets was obtained by regression as well. Whereas nonlinear correlation was obtained for aniracetam SEDDS, which fitted the quadric model very well and the correlation coefficient was 0.972. CONCLUSION: Aniracetam can be released faster from SEDDS than that from conventional tablets, and SEDDS improved the bioavailability of aniracetam significantly. The SEDDS composed by oil and compound surfactants which could enhance the absorption showed the expressing rate of dissolution, and those formed the o/w microemulsion with gastrointestinal liquid could absorb through lymphatic transport route.
