Objective The trial was designed to observe the hemodynamic circadian rhythm in serious heart failure.Methods Totally 140 cases were assigned into the trial;120 cases of serious heart failure were into the heart failure group and 20 cases without heart failure into the control group.Heart rate(HR) and stroke volume(SV)were measured per hour during hospitalization.Results Circadian rhythm existed in two groups,but the heart rates were faster and the stroke stroke volumes lower in the heart failure group.As a whole,the HR and SV were positively correlative in two groups.But the cures of heart rate and stroke volume were separate between 1:00~4:00 before dawn in the heart failure group.The heart rate descended,while stroke volume rose.Conclusion There is divergence phenomenon between heart rate and stroke volume before dawn in serious heart failure.

Objective To evaluate the hemodynamic changes induced by local infiltration with different concentrations of adrenaline during endoscopic sinus surgery under general anesthesia using impedance cardiography (ICG) .Methods Sixty-nine ASA Ⅰ or Ⅱpatients of both sexes (37 males, 32 females) aged 18-60 yrs undergoing elective endoscopic sinus surgery under general anesthesia were randomized to receive local infiltration of nasal mucous membrane with 4 ml of lidocaine containing 20 ?g (group Ⅰ) or 40?g (group Ⅱ) or no adrenaline (group Ⅲ-control) . Hemodynamic changes were monitored by ICG. MAR, HR, cardiac index (CI), systemic vascular resistance index (SVRI) and acceleration index (ACI) were recorded before (baseline) and at 0.75, 1.5, 2.25, 3.0, 3.75, 4.5, 5.25 and 6.0 min after local nasal adrenaline infiltration.Results MAP was significantly decreased while HR increased at 1.5 min after adrenaline infiltration as compared to the baseline values in group Ⅰ and Ⅱ (P

Objective To compare the therapeutic effects with different dosages of sertraline on patients suffering from idiopathic premature ejaculation. Methods IIEF-5 and CIPE questionnaires were completed before the treatment, and 86 patients who met the diagnostic standard of idiopathic premature ejaculation were finally recruited. Subjects were administered sertraline 50 mg/d combined with behavior therapy at stage Ⅰ for 4 weeks. Then, according to the therapeutic effects and the adverse events, all of the patients were divided into 3 groups for stage Ⅱ (another 4 weeks) as ①subjects with good effectiveness but with no or slight adverse events,would continue the treatments ②subjects with no therapeutic effects and with no obvious adverse events were allowed to increase the dosage of sertraline to 100 mg/d;③patients with effectiveness and obvious adverse events were al follows:lowed to reduce the dosage of sertraline to 25 mg/d. Those who had obvious adverse events and no effectiveness quit the study. Results During stage Ⅰ , 63 of 86 patients were effective (73.3%), and 23 patients had no improvement (26. 7%). Thirty-three patients had adverse events (38. 4%), and the remaining 53 patients had no obvious adverse events (61.6%). During stage Ⅱ , of the patients that responded to treatment, 35 patients who had no adverse events and 12 who had slight adverse events continued the treatment. Furthermore, 16 with intolerable adverse events were allowed to reduce the dosage to 25 mg/d. Meanwhile, of those without improvement, 18 subjects without obviousadverse events were allowed to increase the dosage to 100 mg/d, and 5 patients discontinued the treatment. Eight weeks later, among the patients taking 50 mg/d, 47 subjects were effectively with no obvious adverse events. Among the patients taking 25 mg/d, 10 showed improvement, 6 showed no improvement, and 2 had tolerable slight adverse events. Among the patients taking sertraline 100 mg/d,8 witnessed effectiveness, 13 had tolerable adverse events and 2 discontinued the treatment, with 1 having neither effectiveness nor obvious adverse events. The adverse events rate was 21.0% and the total effective rate of 8 weeks of treatment was 80.2 %. Conclusions Sertraline administration is an effective and safe way to treat idiopathic premature ejaculation. Although the effectiveness of the individualized treatment had no obvious improvement comparing routine therapy, there was a notable reduction in the adverse events rate, which increased the patient compliance.

Objective To evaluate the therapeutic effect,as well as the safety,of on-demand sildenafil on men with idiopathic ED.Methods One hundred and four men who met the diagnosis criteria of idiopathic ED were recruited into 2 groups.Among them,46 men who refused or were reluctant to take pharmacotherapy were recruited into the clinical control group with instruction of sexual knowledge and skills.Fifty-eight men who were involved in the on-demand group,were administrated sildenafil 50 mg just 1h before the coitus at thebeginning,then,if needed adjusted the dosage according to the effect and tolerance of the first four administration.The questionnaire of IIEF-5 was completed at the baseline and the end point,and the clinic total effective rate,the fully recovery rate of ED and the adverse events were also evaluated at the end of administration.Both groups were treated for 3 months.The therapeutic effect was reevaluated 1 month and 3 months later,respectively.Results After 3 months treatment,scores of IIEF-5 at the baseline and the end point for control group and on-demand group were as follow:5.2 and 12.6,4.2 and 19.8 ;and the fully recovery rate of ED for each group were as follow:12 (26.1％),56 (96.6％) ; the total effective rate for each group were 27.7％,97.2％ ; 1 month and 3 months after the end point,the fully recovery rate of ED and the total effective rate were evaluated separately,for 1 month:8 (17.4％),56(96.6％) and 19.4％,97.1％; for 3 months:7 (15.2％),55 (94.8％) and 16.4％,96.4％.The side effects in on-demand group (16,27.6％) was little higher than the control group (5,10.9％) (P ＞0.05).Most of the side effects were not only subtle and transient but also would vanish with the time.Accordingly,no one discontinued because of side effects.Conclusions Treatment of idiopathic ED with sildenafil was effective and safe.In terms of the fully recovery rate,total effective rate and effect maintenance,the on-demand group at the end point,even 1 month and 3 months after the end point,showed a great advantage over the control group.

Objective To investigate the relation between microembolic signals (MES) and vertebral basilar artery ste?nosis in patients with brainstem infarction. Methods A total of 156 patients with acute brainstem infarction, who were de?termined the cerebral infarction lesion and vertebral basilar artery stenosis by cranial magnetic resonance imaging and CT an?giography, and were monitored by transcranial Doppler via occipital window of basilar arterial MES monitoring in 7 days of the onset, were divided into microembolus signal negative group (n=136) and positive group (n=20). The clinical data were compared between two groups. The differences of different degrees of stenosis were analyzed in two groups. The differences of different locations of stenosis in patients with vertebral basilar artery stenosis were analyzed in two groups. Logistic regres?sion analysis was used to analyse the factors affecting MES. Results There were no significant differences in age, gender, history of hypertension and diabetes mellitus between the two groups (P<0.05). There were significant differences in the dif?ferent degrees of stenosis between two groups, no or mild stenosis was found in MES-negative group and severe stenosis in MES-positive group (P<0.05). There were 70 cases with no vertebral basilar artery stenosis, 86 cases with mild, moderate and severe stenosis, in which 14 cases were MES-positive and 72 cases were negative. There were significant differences in different locations of stenosis between the two groups. The proportion of multiple infarctions was significantly higher in MES-positive group than that of MES-negative group (P<0.05). The intracranial vertebral basilar artery stenosis and 75%of ver?tebral basilar artery stenosis were the independent risk factors of MES-positive. Conclusion Severe stenosis of the verte?bral basilar artery is more vulnerable to occur MES of posterior circulation, leading to cerebral infarction. Microemboli may be the cause of multiple infarctions in patients with vertebral basilar artery stenosis.

Objective To evaluate the effect of injecting botulinum toxin A (BTX-A) to the external urethral sphincter on detrusor wall thickness (DWT) and the bladder function of spinal cord injury patients with detrusor-sphincter dyssynergia (DSD).Methods Twenty-one adult patients with DSD due to spinal cord injury were recruited.A single 100 IU dose of botulinum toxin A was injected into their external urethral sphincters via an uhrasound-guided transperineal route.DWT,detrusor leak-point pressure (DLPP),post-void residual volume (PRV) and maximum bladder capacity(MBC) were assessed by urodynamic examination and ultrasound evaluation before and 4 and 8 weeks after the injection.Results Four weeks later a significant decrease in PRV was observed,but no significant difference in DWT,DLPP or MBC.After eight weeks the mean DWT value had decreased by 17％,a significant reduction.There were also significant improvements in DLPP,PRV and MBC at eight weeks compared with the of baseline values.Conclusions BTX-A injection to the external urethral sphincter can reduce DWT and improve bladder function in spinal cord injury patients with DSD.
