Chinese Journal of Postgraduates of Medicine 2010;33(15):9-11
Objective To discuss the clinical efficacy and complication of using polypropylene net in pelvic floor reconstruction to treat pelvic floor organ prolapsus. Method From October 2007 to May 2008,15 cases of organ prolapsus of many region defect in pelvic cavity were operated pelvic floor reconstruction, 14 cases had three regional defects,and 1 case had two regional defects. Results All the cases were punctured smoothly without hematoma and injury of blood vessel and organs. The time of operation for 15 cases ranged from 60 to 150 minutes,averaged (85.0±4.3) minutes. The amount of bleeding in operations ranged from 150 to 400 ml,averaged (200.0±0.1) ml. Fifteen cases recovered well after operation without infection.The days in hospital were 5-9 days,averaged (6.0±0.7) days. Following up 1-12 months,pelvic floor structure of all patients were normal,and interrelated symptom disappeared or improved. One case was discovered the net was eroded after 5 weeks. Conclusions Pelvic floor suspension by vagina is a micro operation to treat complicated pelvic floor organ prolapsus. It can accomplish pelvic floor reconstruction and reserve uterus simultaneously, healing efficacy is stable in short-term,but need further observation.

China Pharmacist 2017;20(5):809-812
Objective: To investigate the effects of sulforaphane (SFN) on oxidative stress and Nrf2(Nuclear factor E2-related factor 2)/HO-1(heme oxygenase-1) signaling pathway in renal tubular epithelial cells (HK-2).Methods: HK-2 cells were cultured in vitro and divided into five groups, including the control group, H2O2 group, H2O2+10 μmol·L-1 SFN group, H2O2+20μmol·L-1 SFN group and H2O2+40 μmol·L-1 SFN group.The levels of MDA, NO, GSH and the activity of SOD were measured.The expression levels of Nrf2, HO-1 mRNAR and proteins were analyzed using RT-PCR and Western Blot methods.Results: The levels of MDA and NO in H2O2 group significantly increased when compared with those in the control group, while the levels of GSH and the activity of SOD significantly decreased(P<0.05).The levels of MDA and NO in the cells after the treatment of sulforaphane at different concentrations significantly reduced when compared with those in H2O2 group, while the levels of GSH and the activity of SOD significantly increased(P<0.05).The results of RT-PCR and Western Blot analysis showed that the expression levels of Nrf2, HO-1 mRNAR and proteins in the cells after the treatment of sulforaphane at different concentrations were significantly up-regulated when compared with those in H2O2 group (P<0.05).Conclusion: Sulforaphane can strengthen the antagonism effects on oxidative stress injury in HK-2 cells and the underlying mechanism might be associated with activating Nrf2/HO-1 signal transduction pathway.

Chinese Journal of Tissue Engineering Research 2007;0(44):-
BACKGROUND:Many clinical cases show that micro-implant teeth in the orthodontic treatment are effective with strong resistance.OBJECTIVE:To compare the effectiveness of micro-implant headgear and mouth external devices as a strong orthodontic treatment for front teeth with Angle class Ⅱ and Ⅰmalocclusion.DESIGN,TIME AND SETTING:Case comparative analysis by X-ray was performed at Department of Orthodontics,Hospital of Guilin Medical College from June 2003 to October 2007.PARTICIPANTS:Thirty bimaxillary protrusion patients were divided into two groups:16 cases were treated with micro-implant and the others with extraoral J hook.METHODS:In the anti-implant support group,between the alveolar attack of the upper bilateral first permanent molars and premolars second intervals,micro-titanium alloy implant was implanted as anchorage off space.The implants were early used to do canine backward ligation,after the entire arch-lateral incisor teeth in the upper far in the hook traction devices,space between the implants and hook was closed using a flexible traction.In extraoral J-hook group,J-hook-class Ⅱ traction and headgear extraoral J hook slide were used to strengthen posterior teeth anchorage and close space.The traditional method was used to strengthen support on the lower first and second permanent molars on the upper band combined with support on face-bow lips and lower-profile.Preoperative and postoperative cranial lateral films were taken.MAIN OUTCOME MEASURES:To compare the line of cephalometric X-ray in two groups before and after treatment to observe the change in the location of the first molar.The relation changes of anterior teeth review of coverage and class Ⅱ molar,and improvement of facial convex were observed after treatment.RESULTS:Tissues around the implant were normal,and two cases of micro-implant loosed,which were fixed following re-implantation.Orthodontic treatment of the two groups established the normal relation between over bite and overjet of the front teeth,and corrected class Ⅱmolar relations,with stable location of the first molar,endoduction of upper front teeth and decrease in facial convex.Cephalometric X-ray results showed that in the implant group,the upper first molar advanced,whose crown was forward 0.86 mm,margin of incisors to 6.17 mm;while in the extraoral J hook group,the molars advanced 2.36 mm,and margin of incisors to 4.51 mm.The differences between two groups were significant(P

Academic Journal of Second Military Medical University 2011;32(11):1235-1238
Objective To study the effects of scutellarin on LPS-induced pro-inflammatory cytokine expression in BV2 cells, so as to explore the anti-inflammatory mechanism of scutellarin. Methods The experiment was divided into 5 groups, namely, a normal control group, a model control group (stimulated by LPS), and three Scutellarin treatment groups (0.1, 1, and 100 μg/ml). NF-κB activity was examined by Luciferase Reporter Gene Assay. BV2 cells were treated with LPS; expressions of TNF-α and IL-β mRNA and protein were examined by real-time PCR and Western blotting analysis, respectively. Results Scutellarin treatment greatly inhibited LPS-induced NF-κB activation in pNF-κB 293 cells. The treatment also noticeably inhibited LPS-induced expression of TNF-α and IL-β in BV-2 cells. Conclusion Scutellarin has anti-inflammatory effect, which maybe related to the inhibition of NF-κB-mediated pathway and inhibition of pro-inflammatory cytokine expression.

OBJECTIVE:To establish a method of microbial limit test for Ofloxacin gel. METHODS:Test sample solutions were prepared by MnSO4,CaCl2 and MgCl2 gelout with different concentrations,the numbers of bacteria and control bacteria were detected by membrane filtration method,and the numbers of molds and yeasts were determined by conventional method. RE-SULTS:The conventional method showed the recoveries of Candida albicaus and Aspergillus niger were more than 70% after not treated by gel breaker;the membrane filtration method showed the recoveries of Escherichia coli,Staphylococcus aurus and Baci-lus subtilis were more than 70% after treated by 5% MnSO4,3% CaCl2 and 1% MgCl2;the membrane filtration method could de-tect the control bacteria after treated by gel breaker. CONCLUSIONS:Gel breaker with appropriate concentrations can effectively eliminate the antibacterial activity of Ofloxacin gel. The established method is suitable for its microbial limit test.

Objective To detect the mutant prevention concentration (MPC) of macrolide resistant Streptococcus pneumoniae, to amplify the resistance gene of Streptococcus pneumoniae mutants selected in the mutant selection window (MSW), and to investigate the mechanism in the resistance of Streptococcus pneumoniae to macrolides. Methods The Streptococcus pneumoniae strain ATCC49619 was enriched in broth, and the bacterial concentrations were adjusted to 1010 colony forming units per milliliter. The minimal inhibitory concentration (MIC), MIC for 99 % of input cells (MIC99), provisional MPC (MPCpr), and MPC of roxithromycin and azithromycin for Streptococcus pneumoniae were determined by agar plate dilution method. The ermB and mefA of Streptococcus pneumoniae mutants selected in the MSW were obtained by PCR method and sequencing. Results The MPCs of roxithromycin and azithromycin for ATCC49619 were 0.80 ?g/ml and 0.51 ?g/ml, and the MPC/MIC99 were 5.0 and 3.9. The ermB gene was detected in Streptococcus pneumoniae mutants selected in the MSW. Conclusion Adjustment of the drug dose may limit the enrichment of macrolide-resistant Streptococcus pneumoniae mutant. The mechanism in the resistance of Streptococcus pneumonia to macrolides may be associated with ermB genes carried.
