Objective To evaluate the clinical results of biofeedback and pelvic electric stimulation therapy for stress urinary incontinence in women. Methods Totally 36 women with stress urinary incontinence were prospcctively studied by treating with biofeedback and pelvic electric stimulation therapy (MeprasolBIO2001). All the patients were follow-up for 3 months. Results About 70% of the patients were completely dry and 22% reported subjective improved,the recurrence rate at 3 months follow-up was 60%. Conclusion Biofeedback and pelvic electric stimulation therapy is a safe method for treating stress urinary incontinence. It is effective and easy to perform as an outpatient treatment. But the therapy should be performed for a longterm.

BackgroundMouse has been used in laboratory studies as the model of ocular diseases.Electroretinogram (ERG)is a non-invasive method for primary examination to evaluate retinal function.Though flash ERG has been widely applied in the mouse ocular disease model for the functional assessment of the retinal outer layer,pattern ERG(PERG) is seldom used for inner retinal evaluation.ObjeetiveThe present experimental study was to investigate the recording parameters and method,wave characteristics of PERG and influencing factors in mouse,and to build the foundation for further research.Methods Thirty C57BL/6 mice aged 6 weeks old were included in this research.RETLport ( Roland Consult,Germany) was adopted for the recording of PERG.The positive needle electrode was placed in the cornea,and the reference and earth electrodes were placed under the derma in the cheek and tail.The PERG under different temporal frequencies (0.5,1.0,2.0 and 4.0 Hz),and special frequencies (0.05,0.10,0.20 cpd) were recorded in a photopic environment,and different contrast ratio (95％ and 99％ ) of stimulator or different transmission bands ( 1-100 Hz,5-30 Hz) in the same temporal frequency and spatial frequency were regulated to analyze the influence on mouse PERG.The use of animals was in compliance to the Regulations for the Administration of Affairs Concerning Experimental Animals by the State Science and Technology Commission.ResultsThe latency of N1 PERG showed a negative N1wave at around 37 ms and positive P wave at about 86 ms in adult mice.The amplitude of N1-P was 2-6 μV.Different spatial frequency,temporal frequency and contrast can affect the final results,and the different temporal frequencies were statistically significant.The wave was stable and the amplitude was unaffected at 5-30 Hz transmission bands with pronounced interference (mean amplitude of N1-P waves were(3.40±0.71),(5.08±0.88),(3.21±1.54),(3.85±1.96)μV in 0.5,1.0,2.0,4.0 Hz,F=7.43,P=0.00).ConclusionsPERG wave from adult mouse is similar to that from human.It is a useful method in evaluating the inner retinal function.Appropriate stimulating parameters are critical for recording.

The cytokines have close relationship with the rejection and infection in organ transplantation.The cytokine gene polymorphism influences the secretion of cytokines.The relationship between the rejection and infection in organ transplantation and some cytokines gene polymorphism is reviewed in this article.

Objective To study the relationship of urine RBC morphology between UF-100 urine sediment analytic instrument andphase contrast microscope.Methods The UF-100 urine sediment analytic instrument to analyze 500 urine specimens and study the relation-ship of urine RBC morphology between urine sediment analytic instrument and phase contrast microscope.Results The according perceptionof Normocytic,Microcytic and Non-classified RBC between phase contrast microscope and UF-100 urine sediment analytic instrument RBC-info are 91.4%,94.4%,83.3% respectively,the according perception between phase contrast microscope and RBC-P70Fsc are 94.9%,95.7%,94.7% respectively,and the according perception between phase contrast microscope and RBC Fsc-DW are 84.4%,86.8%,90.5% respectively,the specificity of UF-100 and phase contrast microscope in glomerular hematuria and non-glomerular hematuria are84.3%,88.1% and 83.3%,87.9% respectively.Conclusion The results show that the UF-100 urine sediment analytic instrument issimply operating,fast and high accurate,and which can instruct clinical dignose,therapy and prognosis judgement.

Ten dimeric phthalide racemates (1-10) were isolated from an aqueous extract of the Angelica sinensis root head (Guitou) by separation techniques of column chromatography over macroporous adsorbent resin, MCI resin, silica gel, and Sephadex LH-20, together with preparative thin-layer chromatography and reversed phase HPLC. The racemates were further separated into (+)-/(-)-1-(+)-/(-)-10 with chiral HPLC. Their structures including absolute configurations were elucidated by comprehensive analysis of spectroscopic data, combined with electronic circular dichroism (ECD) and NMR calculations as well as single crystal X-ray diffractions. Compounds (+)-/(-)-1-(+)-/(-)-10 are either new structure or new natural product, named (+)-/(-)-angelidipthalidic acids A-H [(+)-/(-)-1-(+)-/(-)-8] and (+)-/(-)-angelidipthalidols A and B [(+)-/(-)-9 and (+)-/(-)-10], respectively. Meanwhile, dimeric phthalide mono- and bis-lactone derivatives with 3.3′a,8.6′- and 3.6′,8.3′a-coupling patterns as well as determination of their relative configurations are discussed.

AIMTo approach the protective effect of low dose gentamicin against high ototoxic dose of gentamicin.

METHODSThe guinea pigs were randomly divided into four groups: control group, low dose group, low dose protective group and high dose group. Each group received multiple intraperitoneal injections of gentamicin sulphate within different durations. Auditory brain stem response (ABR) was examined one day previous to the first and 24 h after the final injection respectively. The bulla was taken out so that the content of NO, MDA and the activity of LDH in cochlear were determined.

RESULTSThe threshold of ABR was significantly lower in low dose protective group compared with high dose group (P < 0.01). The content of NO (15.86 +/- 1.98 nmol/mg pro) and MDA (19.14 +/- 0.96 nmol/mg pro) in homogenate of high dose group was significantly higher than that of control group, low does group and low does protective group (P < 0.01). The increase of the content of NO and MDA induced by high dose GM could be significantly decreased by low dose GM administration previous to high dose injection (P < 0.01). The activity of LDH in homogenate of high dose group was significantly higher compared with control group, low dos group and low dos protective group (P < 0.01). There was no statistically significant difference of content of NO and MDA among control group, low does group and low does protective group.

CONCLUSIONThe protective effects resulting from previous low dose administration to high dose injection of GM may be related to the decrease of content of NO and MDA and activity of LDH both of which induced by high dose GM.

AIMTo investigate the correlation between reversal effect of cepharanthine hydrochloride (CH) on multidrug resistance (MDR) in drug-resistant cell line EAC/ADR and the nuclear transcription factor-KB (NF-KB).

METHODSCytotoxicity was determined by the tetrazolium (MTT) assay in vitro. An EAC/ADR cell homograft model was established to investigate the effect of CH on reversing MDR in vivo. The constitutive activity and activation of NF-KB by drugs were measured by Dot-Enzyme-linked Immune Sorbent Assay (Dot-ELISA).

RESULTSCH was shown to potentiate the cytotoxicity of ADR, a 13- fold reversal effect of resistance was achieved in vitro. In mice bearing EAC/ADR cell homografts, CH was found to prolong the survival time of animals bearing tumor. Increase in life span over control was 75. 37%. In addition, the constitutive activity of NF-KB and activation of NF-KB by chemotherapy were lowered by CH.

CONCLUSIONThe findings suggest that CH is able to reverse drug resistance and its mechanism may be related to suppressing the constitutive activity and activation of NF-KB by drugs.
