OBJECTIVE To establish a method for simultaneous determi nation of six components in Melastoma dodecandrum and investigate its correlation with antioxidant activity. METHODS Ultra high-performance liquid chromatography （UPLC）method was adopted. The contents of gallic acid ，protocatechuic acid ，isovitexin，rutin and ellagic acid in 23 batches of M. dodecandrum were determined by quantitative analysis of multi-components by single-marker （QAMS）method，using vitexin as the internal reference. Then 1，1-diphenyl-2-picrylhydrazyl（DPPH）free radical method ，2，2′-azino-bis（3-ethylbenzothiazoline-6-sulfonic acid ） diammonium salt （ABTS）method and ferric ion reduction/antioxidant power （FRAP）method were applied to determine the antioxidant activity of 23 batches of M. dodecandrum . Grey correlation analysis and bivariate correlation analysis were used to evaluate the correlation between six components and antioxidant activity. RESULTS The content of vitexin were 0.021％-0.182％. The contents of gallic acid ，protocatechuic acid ，isovitexin，rutin and ellagic acid by QAMS method were 0.008％-0.042％， 0.003％-0.023％，0.071％-0.283％，0.013％-0.140％ and 0.006％-0.021％，respectively. Compared with the results of external standard method ，P was greater than 0.05. Grey correlation analysis showed that the grey correlation coefficients between the contents of six components an d antioxidant activity was 0.727 6- 0.866 9. Bivariate correlation analysis showed that the contents of vitexin ，isovitexin and rutin were positively correlated with antioxidant activity （P＜0.05 or P＜0.01），the content of gallic acid and protocatechuic acid were negatively correlated with antioxidant activity （P＜0.05）. There was no significant correlation between ellagic acid and antioxidant activity.CONCLUSIONS QAMS method is successfully established for the simultaneous determination of six components in M. dodecandrum. The six components in M. dodecandrum are highly correlated with antioxidant activity.

OBJECTIVE: To explore the genetic basis for pedigree affected with hereditary nephrogenic diabetes insipidus (HNDI). METHODS: Next generation sequencing (NGS) with an osteology system gene panel was carried out for the proband. Suspected mutation was validated by Sanger sequencing of two relatives with similar symptoms and two unaffected relatives from the pedigree. RESULTS: The proband was found to carry a c.856C>T mutation of the AVPR2 gene. The same mutation was detected in the two relatives with similar symptoms and one unaffected healthy relative. CONCLUSION The HNDI in this pedigree may be attributed to the c.856C>T mutation of the AVPR2 gene.

Objective To explore the diagnosis and treatment of female bladder outlet obstruction (BOO) with bladder pain as major symptom.Methods From November 2008 to December 2012,21 female patients suffered from urinary frequency,urgency,pain in suprapubic area during bladder filling phase were enrolled in the study.Video-urodynamics (VUD) study combined with free urinary flow rate andresidual urine were performed in all patients in order to make the diagnosis of BOO clearly.The mean maximum urinary flow rate was (11.5±3.6) ml/s,and the mean maximal detrusor pressure was (39.1±17.8) cmH2O.Combining with the voiding radiography,19 patients were diagnosed as bladder neck obstruction,and the other 2 were diagnosed as urethral stricture.All patients were accepted the hydrodistension under the epidural anesthesia.The bladder biopsy was performed if the typical glomerulations were observed under the cystoscopy.Bladder neck incision and urethral dilatation were performed on these patients respectively.Symptom changes of bladder pain were recorded by using O'Leary-Sant scale,the pain,urgency,frequency symptom (PUF) scale and quality of Life (QOL) Scale.The data were collected within 48 months postoperation,respectively.Results The pathological findings of bladder mucosa biopsy showed acute or chronic inflammation in all patients.The mean follow-up was 6.7±5.9 months.We compared the corresponding data such as:voiding times per day,nocturnal frequency,O'Leary Sant scores,PUF and QOL between pre and post-treatment.Significant differences were observed during all corresponding data (P＜0.05).The voiding times per day changed from 24.3± 11.8 to 13.0±5.9.The nocturnal frequency decreased from 6.5±2.7 to 3.3± 1.6.O'Leary Sant scores changed from 24.6±7.3 to 14.7±7.4.The PUF scores changed from 22.9±6.2 to 12.0± 7.1.And the QOL scores changed from 5.0±0.8 to 2.9±1.5.Conclusions Free urinary flow rate and residual urine combined with VUD are very important in diagnosing female BOO with bladder pain as major symptom.Bladder pain symptoms will be significantly improved after the obstruction was relieved according to VUD results.

Objective To elucidate if detrusor overactivity(DO)has influence on patients with benign prostate hyperplasia.Methods Forty-seven patients who were suspected to suffered from BPH were divided into two groups according to whether have DO in pre-operative urodynamic analysis.There were 22 patients in DO group and 25 in non-DO group.All patients received transurethral resection of prostate (TURP).Pre-operative variables such as relevant clinical data,International Prostate Symptom Score (IPSS),quality of life (QOL) index,maximum urine flow rate(Q~(max)) and pressure-flow study data were recorded.Patients were monitored after operation and the corresponding data were recorded.Results Prostate size in DO group was (77±25)ml,and in non-DO group was (56±27) ml,P=0.02;first desire bladder volume in DO group was (104±36) ml,and in non-DO group was (161±54) ml,P=0.001;urgent desire bladder volume in DO group was (245±73) ml,and in non-DO group was (328±94)ml,P=0.006;pre-operative residual urine in DO group was (71±49)ml,and in non-DO group was (149±125)ml,P=0.015;linPURR obstruction grade in DO group was 4.63±0.95,and in non-DO group was 3.35±1.90,P=0.014.The IPSS and QOL before and after operation had no significant differences between the 2 groups.Conclusions The patients with larger prostates and more severe bladder outlet obstruction are more likely to have DO.Patients with DO had smaller bladder volume and residual urine volume before operation.DO has no significant effect on BPH patient's IPSS and QOL.

Objective To study the influence of overactive bladder (OAB) on the symptoms and quality of life (QoL) in patients after Transvaginal Tape-Obturator (TVT-O) treatment for stress urinary incontinence (SUI).Methods Eighty-two SUI women underwent TVT-O were included in this study.The perioperative ICI-Q-SF scores,including frequency of leakage,volume of leakage,and QOL scores,were collected to study the perioperative OAB prevalence and the influence of OAB on the improvement on the symptoms and QOL after TVT-O.Results The total efficacy of TVT-O was 95%.The average symptom and QOL scores in all patients decrease from (8.17±2.29)and (7.95±2.16)to (1.84±2.34)and(1.32±2.24)after TVT-O,P＜0.05.The prevalence of OAB decreased from 46% to 24% after TVT-O,P＜0.05.The average post-operation symptom and QOL scores of the pre-operation non-OAB group were (1.09±1.60)and(0.82±1.45),while those of the OAB group were (2.71±2.75) and (1.89±2.82),P＜0.05.The average post-operation symptom and QOL scores of the post-operation non-OAB group were (1.06±1.68) and (0.56±1.15),while those of the OAB group were (4.25±2.49) and (3.65±3.10),P＜0.05.Conclusions TVT-O is effective for female stress urinary incontinence and contributes to the significant improvement of symptoms and QOL in patients with OAB.The treatment will not raise the prevalence of OAB in itself.

Objective To investigate changes in symptoms and quality of life (QOL) score before and after transurethral resection of the prostate ( TURP), and their related factors. Methods Forty-seven elderly male patients of benign prostate hyperplasia (BPH) with lower urinary tract symptoms were enrolled in the study, with an average age of 72 years. They all were undergone with TURP and evaluated with international prostate symptoms score (IPSS), QOL score, maximal urine flow rate (Qmax), residual urine volume, pressure-urine flow rate and prostate size before and after the procedure. Changes in these parameters and their related factors were analyzed. Results No complication was observed during TURP in the 47 patients. After TURP, two patients suffered from distal urethra stricture, one from retrograde ejaculation and six from aggravated urgent incontinence, and symptoms relieved with symptomatic treatment in all of them. Significant difference in overall IPSS, irritant score and obstructive score pre- and post-operation was observed P ＜ 0.01, i. e. , 22.7 ±4.9 and 10.5 ± 5.8, 10.5 ± 5.8 and 6.3 ± 3.5, and 12.1± 3.9 and 4.2 ± 3.3, respectively. QOL score was 4.6 ± 0.9 and 2.3 ± 1.3, Qmax (5.8 ± 2.9 ) ml/s and (12.4 ±5.2) ml/s and residual urine volume (99 ± 16) ml and (34 ± 19) ml pre- and post-operation,respectively ( all P ＜ 0.01 ). Follow-up time after the procedure, prostate volume and bladder volume at urgent urination desire all correlated with post-operation IPSS ( r = 0.751, P ＜ 0.05 ), and follow-up time after the procedure and age also significant correlated with post-operation QOL score (r = 0.470, P ＜ 0.05 ).Conclusions Overall IPSS, irritant score, obstructive score and QOL score improved significantly after TURP in symptomatic BPH patients, probably by varied related factors.
