ObjectiveTo assess a simple apparatus measuring displacement of pelvis in clinical application.MethodsTwo testers measured the displacement of pelvis of 20 healthy young subjects moving their body forward, backward, leftward and rightward in standing position. The reliability of inter- and intra-tester was tested with intraclass correlation co-efficiency (ICC). And the validity between this method and Functional Reach Test (FRT) was tested.ResultsThe ICC of inter- and intra-tester were 0.91～0.97 and 0.94～0.98 respectively, and correlated with FRT (r=0.88, P<0.01).ConclusionThis simple apparatus can be used in a balance test.

Some factors may induce accidents during physiotherapy for stroke patients. This article would summarize the general risk factors and discuss the management.

Objective To evaluate short-term clinical effects of modified total pelvic floor reconstruction surgery in treatment of severe pelvic organ prolapse.Methods Thirty-nine cases with severe pelvic organ prolapse including vault prolapse diagnosed by pelvic organ prolapse quantification (POP-Q) system received modified total pelvic floor reconstruction surgery.Clinical parameters associated peri-operative period and 12 months after surgery and complications were analyzed Results Median operation time was 70 minutes (30-240 minutes),median blood loss was 100 ml (10-200 ml).Seventy-seven percent (30/39) patients were able to micturate spontaneously in the next morning after surgery with postvoid residual volume less than 100 ml (0-650 ml).No severe intra-operative complications were recorded and the rate of postoperative morbidity was 20% (8/39 ).Median post-operative hospital stay was 4 days (1-11 days).The patients were followed up at median 24 months(13-29 months).According to POP-Q system evaluation,the successful rate of operation reached 100% .Two cases (5%,2/39) were recorded as symptomatic recurrence which manifested as posterior wall prolapse within 24 months after operation.During follow-up,8% (3/39) patients were found to have erosion within 7 months after surgery,and urgent urinary incontinence was observed in 5% (2/39) cases,while constipation occurred in 8% (3/39) cases.The most remarkable complication was dyspareunia (36%,5/14); while 50% (7/14) experienced better sexual life after surgery.Conclusions Modified total pelvic reconstruction is a safe,efficient and micro-invasive surgery in treatment of severe pelvic organ prolapse.However,its influence on post-operative sexual life should be concerned.

Objective To establish a novel method for the determination of betaine in serum by high performance liquid chromatography with UV detection.Methods Pre-column derivatization of serum was performed directly in acetonitrile without extraction with p-bromophenacyl bromide and 18-crown-6 ether as catalyst.The p-bromophenacyl ester derivatives were then separated by Supelcosil LC-SCX, using an was 0.8 ml/min and the effluent was monitored at 259 nm. Betaine was used for preparation of standard curve and quantification with external standards.Results The linearity of this method was 6.25-200.00 μmol/L,the regression was 0.999 8.The detection limit was 3.0 μmol/L.The within-day imprecision was 1.88%-3.79% ( average 3.24% ), the between-day imprecision was 3.14%-6.76% ( average 4.39% ), the recovery rates were 95.89%-102.86% (average 99.16% ).Conclusion This method is sensitive, rapid, accurate and suitable for the research and routine clinical practice.

In order to optimize the testing methods for Paeonia suffruticosa seed quality, and provide basis for establishing seed testing rules and seed quality standard of P. suffruticosa. The seed quality of P. suffruticosa from different producing areas was measured based on the related seed testing regulations. The seed testing methods for quality items of P. suffruticosa was established preliminarily. The samples weight of P. suffruticosa was at least 7 000 g for purity analysis and was at least 700 g for test. The phenotypic observation and size measurement were used for authenticity testing. The 1 000-seed weight was determined by 100-seed method, and the water content was carried out by low temperature drying method (10 hours). After soaking in distilled water for 24 h, the seeds was treated with different temperature stratifications of day and night (25 degrees C/20 degrees C, day/night) in the dark for 60 d. After soaking in the liquor of GA3 300 mg x L(-1) for 24 h, the P. suffruticos seeds were cultured in wet sand at 15 degrees C for 12-60 days for germination testing. Seed viability was tested by TlC method.

In order to establish the quality classification criteria of Paeonia suffruticosa seeds, thirty-one batches of P. suffruticosa seeds from different provenances were selected. The seed rooting rate, seed germination rate, seed purity, seed viability, 1,000-seed weight and moisture content were determined and analyzed through SPSS 20.0 software. Seed rooting rate, seed germination rate and seed purity were selected as the main index for classification, while 1,000-seed weight, seed viability and moisture content could be used as important references. The seed quality grading of P. suffruticosa was set as three grades. The seed quality of each grade should meet following requirements: For the first grade seeds, seed rooting rate ≥ 80%, seed germination rate ≥ 80%, seed purity ≥ 90%, seed viability ≥ 80%, 1,000-seed weight ≥ 250 g, moisture content, ≤ 10. For the second grade seeds, seed rooting rate ≥ 50%, seed germination rate ≥ 60%, seed purity ≥ 70%, seed viability ≥ 75%, 1,000-seed weight ≥ 225 g, moisture content ≤ 10. For the third grade seeds, seed rooting rate ≥ 20%, seed germination rate ≥ 45%, seed purity ≥ 60%, seed viability ≥ 45%, 1,000-seed weight ≥ 205 g, moisture content ≤ 10. The quality classification criteria of P. suffruticosa seeds have been initially established.
