This paper aims to develop a method for the determination of aloe-emodin, rhein, chrysophanol and physcion and study the pharmacokinetic properties of four anthraquinones in rat plasma after oral administration of gardenia and rhubarb decoction. The plasma concentrations at different time points of four anthraquinones were determined by HPLC-FLD method. Plasma samples were extracted with liquid-liquid extraction procedure. Plasma samples were separated on a C18 column (4.6 mm x 150 mm, 5 μm), using 0.2% acetic acid and methanol as mobile phase at a flow rate of 1.0 mL min(-1) with gradient elution. The excitation and emission wavelengths were set at 430, 525 nm, respectively. DAS 2.0 software was applied to calculate the pharmacokinetic parameters. The results showed four anthraquinones can be absorbed. The main parameters of aloe-emodin, rhein, chrysophanol and physcion were as follows: C(max) for aloe-emodin was (0.085 ± 0.058), (3.772 ± 1.152), (0.464 ± 0.267), (0.028 ± 0.008) mg x L(-1) respectively; t(max) for rhein was (1.042 ± 0.510), (0.805 ± 0.307), (1.167 ± 0.283), (0.616 ± 0.162) h respectively; t½ for chrysophanol was (3.557 ± 1.250), (6.879 ± 1.126), (5.196 ± 2.032), (4.337 ± 1.816) h; AUC(0-t) for physcion was (0.504 ± 0.130), (9.558 ± 1.106), (2.545 ± 1.554), (0.052 ± 0.018) mg x h x L(-1). This paper developed a selective, accurate and sensitive HPLC-FLD method for the simultaneous determination of four anthraquiones in rat plasma.

Objective To assess the safety and efficacy of the transohturator tape (TOT) for surgical treatment of female stress urinary incontinence (SUI). Methods Clinical data of 206 TOT procedures for female urinary incontinence from Jan 2007 to Dec 2009 was retrospectively analyzed.Thirty-one women were identified as having mixed stress urinary incontinence.The mean age was 54.29 years(range,32-81 years),themean disease coursewas 10.31 years (range,1-40 years),and the mean follow-up time was 17.3 months (range,3-39 months).Therapeutic effects were assessed by Grouts-Blaivas outcome score.The results of the operation,complications and changes of urodynarnics were observed. Results The TOT operations were conducted under local anesthesia.The mean operative time was 23.9 min (range,16-35 min),Mean blood loss was 17.8 ml(range,15-30 ml).Short-term complications were as follows:thigh pain 14.08%,dysuria 5.83%,urinary posture change 0.97% and urinary retention 0.49%.The long-term complication rate was 0.97%,including vaginal wall defect and tape exposure in one case:the burr of tape exposure and sex life influence in one case.Long-term symptoms disappeared completely in 202 cases.The cure rate was 98.06%,and the rate of satisfaction was 100%. Conclusions Our results demonstrate that TOT procedure is a minimally invasive,safe and effective surgical treatment for stress urinary incontinence.

Objective:To assess the consequences of switching aspirin dosage from 100 mg/d to 40 mg/d on cardiovascular benefit,bleeding risk and platelet aggregation in very elderly patients. Methods:Arachidonic acid induced platelet aggregation(AA-Ag)was measured in 537 patients aged 80 or older treated with aspirin (100 mg/d).In the study,100 patients with low on-treatment platelet ag-gregation and at high risk of bleeding and low risk of cardiovascular events,were switched to aspirin (40 mg/d)and their platelet aggregation was measured again 7 days later.Their bleeding and upper gastroin-testinal symptoms were also recorded in following 3 months.Results:The study observed a heterogeneous distributed aspirin 100 mg/d AA-Ag (range:0.42% to 28.78%)in the 537 very elderly patients.Aspi-rin 100 mg/d AA-Ag before the switch in aspirin 40 mg/d group was 5.00% ±2.32% and the rate of the patients with low on-treatment platelet aggregation was 71.00%.The rates of melena or occult blood positive,other minimal bleeding,upper gastrointestinal symptoms and a history of gastrointestinal bleeding in 40 mg/d group were higher than those in 100 mg/d group.On a regimen of aspirin 40 mg/d,AA-Ag increased to 11.21% ±4.95%(range:2.12% to 28.84%)with 95.00%of the patients with AA-Ag<20%and the rate of the patients with low on-treatment platelet aggregation was 15.00%.Multiple vari-able analysis revealed that aspirin 40 mg/d AA-Ag was significantly influenced by aspirin 100 mg/d AA-Ag,BMI and platelet counts.The rate of gastrointestinal bleeding decreased from 12.00% to 5.00%, and upper gastrointestinal symptoms decreased from 59.00% to 21.00% after the switch in 40 mg/d group.Conclusion:Switching aspirin dosage from 100 mg/d to 40 mg/d reduces the bleeding events and improves upper gastrointestinal symptoms,thus inhibiting platelet aggregation effectively in very elderly patients.

Objective To explore the developmental tendency of eco-migrant children's extroversive behavior and the relationship between extroversive behavior and personality and family environment.Methods 856 eco-migrant children(aged 6-16)participated in the present longitudinal study.At first time the Child behavior checklist(CBCL),Eysenck personality questionnaire (EPQ) and Family environment scale (FES) were used to assess their behavioral problems,personality and family environment.Participants' parents subsequently completed measures assessing behavioral problems every nine months for 27 months.Data were analyzed using hierarchical linear modeling analyses.Results The scores of extroversive behavior in eco-migrant children were(10.09±7.11) at first time,(7.66±7.56) at the second wave,(8.54±7.49)at the third wave and(8.11±7.33) at the last time.During the longitudinal period,the descending trend of eco-migrant children's extroversive behavior was significant (β=-0.51,P<0.05).The scores of psychoticism,neuroticism,family conflict,organization,cohesion and cultural factors were differently correlated with children's extroversive behavior (β=-0.67-0.32,P<0.05).Family conflict predicted the developmental trend of children's externalizing (β=-0.46,P<0.05).Conclusion During the longitudinal period,the level of eco-migrant children's extroversive behavior decreased,and personality and family environment have significant influences on it.

Objective To analyze the efficacy and safety of suprapubic arc sling (SPARC) and transobturater vaginal tape (TOT) for female stress urinary incontinence (SUI). Methods A retrospective study was conducted on 275 women ( 139 in TOT group and 136 in SPARC group) in our institute from September 2008 to January 2011.We had compared the complications of the two groups.All the patient's ICI-Q-SF scores and PISQ-12 scores were collected.We compared the pre- and post-operative Qmax and PVR to find out if SPARC or TOT tap cause bladder outlet obstruction (BOO). Results The operative time was 25.1 ± 3.3 min for TOT and 34.8 ± 5.6 min for SPARC.There was statistical difference between the two groups in the aspects of operative time (P =0.00).The improvements of average symptom and QOL scores in patients undergoing TOT and SPARC were statistically significant (P =0.00).The improvements of the PISQ-12 scores in the two groups were statistically significant (P <0.05 ) as well.There was no significant difference (P > 0.05 ) in the total cure rate of TOT and SPARC.The complications post SPARC and TOT were low.In the TOT group,the Qmax changed from 30.2 ± 8.7 ml/s per-operatively to 24.9 ± 8.6 ml/s post-operatively in a week.PVR changed from 1.6 ± 4.2 ml pre-operatively to 3.2 ± 6.5 ml post-operatively in a week.In the SPARC group,the Qmax changed from 31.7 ±9.4 ml/s pre-operatively to 26.9 ± 8.9 ml/s post-operatively in a week.PVR changed from 1.4 ± 3.7 ml pre-operatively to 3.5 ± 6.3 ml postoperatively in a week.All the changes were significant ( P < 0.05 ).And in the SPARC group,the Qmax changed from 31.2 ± 10.0 ml/s pre-operatively to 26.2 ± 9.1 ml/s post-operatively; the PVR changed from 1.8 ± 3.2 ml pre-operatively to 4.7 ± 8.8 ml post-operatively (P < 0.05). Conclusions Both the TOT sling and the SPARC sling have high cure rates for SUI.But the retropubic sling may lead to BOO and other complications,so the transobturate sling is a better treatment option for SUI.

Epiretinal membrane (ERM) is a relatively common macular disease that forms along the surface of the internal limiting membrane (ILM) of the retina to some reason.The pathogenesis is not clear.Microincision vitrectomy surgery has been confirmed as a minimally invasive and very safe modality of treatment.Deciding when to perform a vitrectomy can be difficult.There are many factors which can affect the postoperative visual acuity,such as age,the thickness of macular,integrity of photoreceptor inner segment/outer segment (IS/OS) junction.
