ABSTRACT
Objective To analyze the gonadal hormone and seminal plasma of patients with abnormal semen liquefaction and investigate the influence mechanism in order to provide guidance for the diagnosis and treatment. Methods 152 men of childbearing age were divided into two groups according to the liquefaction time (cut?off point: 60 minutes). Routine semen parameters,gonadal hormone and seminal plasma were tested and compared between the above groups. T?test was applied to compare individual gland function (pH value,neutralα?glycosidase,fructopyranose,seminal plasma zinc and citric acid) and gonadal hormone (FSH,LH,PRL,T and E2). Logistic regression analysis was adopted to probe the influencing factors for abnormal semen liquefaction. Results Seminal pH value (7.47 ± 0.13 vs. 7.32 ± 0.18),citric acid(51.12 ± 12.95 vs. 83.11 ± 33.46)and FSH (4.40 ± 1.03 vs. 4.85 ± 1.50)levels were significant different between the two groups (P < 0.05),but the other indexes showed no significant difference. Correlation regression analysis showed that semen liquefaction capacity has correlative relationship with seminal plasma fructose (OR=2.644),citric acid (OR=0.922),serum T (OR=1.029) and E2,while no correlative relationship with other indexes. Conclusions Correlation between two glands (seminal vesicle and prostate) and balance in the two hormones (T and E2) influence the liquefaction time. Specific causes should be distinguished before diagnosis.
ABSTRACT
Objective To compare the effect of kidney-tonifying blood-activating recipe (KBR) and Aescuven Forte Tablets ( AFT) in improving the sperm quality of varicocele-induced male sterility, thus to optimize the therapeutic therapy for varicocele-induced male sterility. Methods A total of 102 varicocele-induced male sterility with abnormal sperm parameters after conservative treatment were randomized into KBR group (N=53) and AFT group ( N=49) . KBR group was given KBR plus natural vitamin E and AFT group was given AFT plus natural vitamin E, and the treatment lasted for 8 continuous weeks. Before and after treatment, the quality of seminal fluid was analyzed, sperm quantization parameters such as total number of sperm (TNS) , total number of progressive motility sperm ( TNPS) , total number of normal form sperm ( TNNS) and total number of nor mal form and progressive motility sperm ( TNNPS) were observed, and the improvement rate of sperm quantization parameter was compared. Results (1) Before treatment, the differences of TNS, TNPS, TNNS and TNNPS were insignificant between the two groups ( P>0.05) . After treatment, TNNS was not improved in AFT group ( P>0.05) , but TNS, TNPS, TNNPS were much improved in both groups ( P<0.01 compared with those before treatment) . The improvement of KBR group was superior to that of AFT group ( P<0.05) . ( 2) The improvement rate for TNS, TNPS, TNNS, TNNPS was 90.57%, 79.25%, 67.92%, 77.36%in KBR group, and was 75.51%, 73.47%, 28.57%, 61.22% in AFT group respectively. The improvement rate for TNS and TNNS in KBR group was superior to that in AFT group ( P<0.05 or P<0.01) . Conclusion Varicocele-induced male sterility patients usually have the syndrome of kidney deficiency and blood stasis, so KBR, which has the function of tonifying kidney and activating blood, has synergistic action on the effect of AFT in improving sperm quality of varicocele-induced male sterility patients.
ABSTRACT
Objective To investigate the role of dimethylarginine dimethylaminohydrolase-2 (DDAH-2)/asymmetric dimethylarginine(ADMA)in pathophiology of preeclampsia by detecting expression of DDAH-2 in placenta and serum plasma ADMA.Methods From Jan.2004 to Jan.2005,30 preeclampsia patients(PE group)were chosen in the Third Affiliated Hospital.Guangzhou Medical College matched with 10 normal third trimester women as control(control group).The placental DDAH-2 mRNA expression was detected by fluorescence quantitative polymerase chain reaction(FQ-PCR)and the plasma concentration of ADMA WSB determined by high performance liquid chromatography(HPLC).Results(1)The level of ADMA in PE group was significantly higher that than of control group[(18.0±7.2)mg/L vs.(10.3±1.7)mg/L,P<0.01].The expression level of ADMA in preeclampsia occurring before 34 gestatinal weeks WaS significantly higher than that of preeclampsia occurring after 34 gestational weeks[(22.0±7.0)ms/L vs.(12.7±2.8)mg/L,P<0.01].(2)The Placental DDAH-2 mRNA expression in preeclampsia patients was remarkably lower than that of control group[1×10(5.23±0.45)copy/μlvs.1×10(5.65±0.08)copy/μl,P<0.01].The Placental DDAH-2 mRNA in preeclampsia occurring before 34 gestatinal weeks was significantly lower than that of preeclampsia occurring after 34 gestational weeks [1×10(5.02±0.46)copy/μl vs.1×10(5.61±0.19)copy/μl,P<0.01].Conclusion Our results suggested that low expression of DDAH-2 in placenta and increased serum ADMA level might confer the susceptibility to preeclampsia.
ABSTRACT
Objective To investigate the early impact of incremental peritoneal dialysis.Methods 109 new peritoneal dialysis patients treated with incremental peritoneal dialysis were included in the present study.Clinical data,dialysis adequacy and nutritional status were evaluated at the initiation of dialysis and at 3 months after PD.Results The peritoneal dialysis patients achieved good results in the dialysis adequacy and nutrition at the end of the 3rd month.The patients' comorbidities reduced.BP and blood work improved significantly during the first 3 months.Conclusion Our results suggest that incremental PD improve patients clinical status even at the early stage of dialysis.
