Objective To study the chemical constituents in ethanol extract from the carpophore of Xanthoceras sorbifolia and explore a new potential part.Methods The constituents were isolated by macroporous resin and silica gel column chromatography and their structures were elucidated by the phisi-cochemical properties and spectral evidence.Results Compounds Ⅰ-Ⅵ wre obtained and their structures were identified as 21-angeloyl-24-hydroxy-R1-barrigenol(Ⅰ),23-hydroxybetulinic acid(Ⅱ),3?,23-dihydroxy-lup-20(29) en-28-oic acid-3-caffeate(Ⅲ),22,23-dehydroxy-?-chondrillasterone(Ⅳ),3-oxotirucalla-7,24-dien-21-oic(Ⅴ),and ?-spinasterol-3-O-?-D-glucopyranoside(Ⅵ),respectively.Conclusion Compound Ⅰ is a new natural product and compounds Ⅱ-Ⅳ are isolated from the plants of Xanthoceras Bunge for the first time.

Objectives:To study the effect of triptolide(Tri) on fibroblast cells in vitro culture, morphologically and kinetically. Methods:Light microscope(LM)and electron microscope(EM)were employed to detect the morphological changes in Tri group. Cell DNA content and apoptosis were assayed by flow cytometry (FCM). Results:In Tri group, fibroblast cells showed less density, slimmer body, abnormally and typical apoptosis under LM, while rarefaction and content of rough endoplasmic reticulum(RER) decrease, and apoptosis in different stages could be seen under EM. In FCM,AI elevated remarkably in Tri groups, and the effect is dose dependent, with cell cycle uninfluenced at all. Conclusions:The mechanism of triptolide on hypertrophic scars is related to its promotion on fibroblast apoptosis and inhibition of collagen excretion.

Posterior pedicle fixation-based dynamic stabilization is now densely studied in the non-fusion spine surgery. The method is characterized by the motion preservation of segmental lumbar, avoidance of the stress change after fusion surgery, and adjacent disc degeneration. Posterior pedicle fixation-based dynamic stabilization systems have undergone fast development and are now used for the treatment of degenerative lumbar spine disease. As an innovation of traditional fusion surgery, the clinical evaluation of its efficacy has become a focus of study among spine surgeons. In this paper, we review the recent progress in the clinical efficacy of posterior pedicle fixation-based dynamic stabilization.

Objective To investigate the association of AcrAB-tolC efflux pump and marA-soxS-rob regulon with ciprofloxacin-resistance in Shigella flexneri isolates.Methods Forty five strains of Shigella flexneri were isolated in stool samples collected from outpatient diarrhea clinics in Tianjin from 2009 to 2013.The antimicrobial susceptibility of bacteria was analyzed by Kirby-Bauer disk diffusion method.Ten ciprofloxacin-resistant Shigella flexneri isolates and 10 ciprofloxacin-sensitive isolates were randomly selected.The gyrA and parC genes,plasmid mediated quinolone resistant (PMQR) determinants,efflux pump genes (acrA,acrB) and regulation genes (marA,soxS,rob) were screened and sequenced.Minimum inhibition concentrations (MICs) of the strains were determined before and after efflux pump inhibitor carbonyl cyanide m-chlorophenylhydrazone (CCCP) was added.The expression of acrA,acrB,marA,soxS and rob genes in ciprofloxacin-resistant and ciprofloxacin-sensitive strains was detected by realtime fluorescence quantitative RCR (RT-PCR),and the differences of expression were evaluated using t test.Results Both gyrA and parC mutations were detected in all ciprofloxacin-resistant strains; qnrS1 was positive in ciprofloxacin-resistant strain CR2 and aac(6')-Ib-cr was positive in ciprofloxacin-resistant strain CR5.Efflux pump genes and regulation genes were not detected in ciprofloxacin-sensitive strains,while soxRS mutation was detected in all ciprofloxacin-resistant strains except CR10.MICs of quinolones in ciprofloxacin-resistant strains decreased to one-fourth or one-eighth when CCCP added,while not changed or only decreased to one-half in ciprofloxacin-sensitive strains.Expressions of acrA,acrB,marA and soxS were significantly higher in ciprofloxacin-resistant strains than those in ciprofloxacin-sensitive strains (P ＜ 0.05 or P ＜ 0.01).Conclusion Efflux pump may involve in the high-level ciprofloxacin resistance in Shigella flexneri through activating transcription of efflux pump genes by marA-soxS-rob regulon,in which soxRS mutation may play an important role.

Objective To summarize first aid and nursing key points of 3 patients with cranial orbital injury. Methods Three patients with cranial orbital injury were nursed from January 2014 to March 2014, including routine nursing, nursing of eye and cerebrospinal fluid leak and prevention of infection. Results The hospital stay of the 3 patients was from 8 to 23 d, during which 1 contracted cerebrospinal fluid leakage and another rupture of left eye ball. All patients were well recovered after discharge and could be self cared in life for their own, with one patient blind on the left eye and the other 2 with facial disfigurement. Conclusions The patients with cranial orbital injury is critical. Therefore, well done first aid and nursing are key for a better prognosis.
