ObjectiveTo observe the effect of acupoints stimulation with silver spike point therapy on insomnia.Methods60 patients with insomnia were randomly divided into the trial group and control group with 30 cases in each group. Patients of the trial group were treated by acupoints stimulation with silver spike point therapy and patients of control group were treated only with Clonopin. All patients of two groups were tested with Self-Rating Scale of Sleep (SRSS) before and after treatment.ResultsThe curative effect rate of the trial group was 86.6%; that of the control group was 60%; the curative effect of the trial group was superior to the control group (P<0.05). SRSS difference of the trial group pre-and post-treatment was 12.79±3.20; that of the control group was 10.1±3.89. There was also a significant difference between two groups (P<0.01).ConclusionThe silver spike point therapy has the better curative effect on insomnia than Clonopin.

Objective To evaluate the effects of sevoflurane anesthesia on the sleep architecture of rats.Methods Sixteen pathogen-free healthy male Sprague-Dawley rats,aged 10-12 weeks,weighing 300-350 g,were divided into 2 groups (n=8 each) using a random number table:control group (group C) and sevoflurane group (group S).Each rat was implanted with a transmitter for recording electromyogram and electroencephalogram via telemetry.The rats were exposed to 2.4％ sevoflurane and pure oxygen 1.5 L/min for 5.5 h followed by 0.5 h washout with pure oxygen in group S,and the rats were exposed to pure oxygen 1.5 L/min for 6 h in group C.Then the rats were taken into the sleep monitoring box,and the 24 h after anesthesia was divided into 4 time periods according to the circadian rhythm:L1 (14:00-20:00),D1 (20:00-02:00),D2 (02:00-08:00) and L2 (08:00-14:00).The total time spent on wakefulness,on non-rapid eye movement (NREM) sleep and on REM sleep,the number of wakefulness,NREM sleep and REM sleep,and the time spent on wakefulness,on NREM sleep and on REM sleep during each time period were recorded using Version 3.0 Neurosore software.Results Compared with group C,the total time spent on wakefulness was significantly shortened,the total time spent on REM sleep was prolonged,the number of NREM sleep was increased,the time spent on REM sleep in L1 and D1 time periods was prolonged,the time spent on wakefulness in D2 time period was shortened,the time spent on NREM sleep was prolonged (P＜0.05),and no significant change was found in the total time spent on NREM sleep or the number of REM sleep and wakefulness in group S (P＞0.05).Conclusion Sevoflurane anesthesia can change the stability of sleep architecture,increase REM sleep and reduce wakefulness in rats.

OBJECTIVETo examine the effect of ONO-AE3-208, an EP4 antagonist, on the formation of bone metastasis from prostate cancer in mice.

METHODSThirty-four 6-week old nude mice were divided into an experimental and a control group of equal number to be treated by intraperitoneal injection of ONO-AE3-208 and double distilled water, respectively. Then PC3/LUC cells were constructed by stably transfecting luciferin to prostate cancer PC3 cells and inoculated into the left ventricle of the mice to establish an animal model of systemic bone metastasis. The time of metastasis formation, photon tumor burdens, and changes of the survival curves after modeling were compared between the two groups of mice.

RESULTSAt 30 days after modeling, bioluminescence imaging analysis showed that the photon tumor burdens were significantly increased in a time-dependent manner in the control group in comparison with those in the experimental group (P < 0.01). The rate of metastasis formation was significantly higher in the former than in the latter (93.3% vs 33.3%, P < 0.001). The median time of metastasis formation was 29 d (95% CI 26.547 - 35.262) in the experimental animals as compared with 21 d (95% CI 17.213 -24.787) in the controls (P < 0.001).

CONCLUSIONEP4 antagonist ONO-AE3-208 can inhibit the formation of bone metastasis from prostate cancer in mice.

OBJECTIVE:To establish the method for the determination of mildronate in human plasma and urine,and to study the pharmacokinetic characteristics in healthy volunteers. METHODS:After precipitating plasma and urine sample,LC-MS/MS method was adopted. Dikma Diamonsil C18 column was used with mobile phase consisted of methanol-water(containing 0.2% for-mic acid,0.3% ammonium acetate)(31∶69,V/V)at the flow rate of 0.6 ml/min. ESI was adopted in MRM mode,by using nega-tive ion. The ion for quantitative analysis were m/z 147.10→58.20 (mildronate) and m/z 152.00→110.10 (internal standard,acet-aminophen). The pharmacokinetic parameters of mildronate with single administration and multiple administration were calculated by using DAS 2.1 software and compared. RESULTS:The linear range of mildronate in plasma were 0.02-20 ng/ml(r=0.999 3) and in urine were 0.05-40 ng/ml(r=0.998 2). The lowest limits of quantitation were 0.02 and 0.05 ng/ml. Precision and recovery met the requirements of biological specimen determination,and endogenous impurities hadn’t effect on the determination. The main pharmacokinetics parameters of low-dose,medium-dose and low-dose(250,500,750 mg)of mildronate in plasma with single ad-ministration were as follows:t1/2 were(3.39±0.81),(5.52±0.57)and(5.32±0.96)h;tmax were(0.80±0.45),(1.38±0.43)and (1.10±0.36)h;cmax were(4.17±1.46),(8.08±1.04)and(15.04±1.86)ng/ml;AUC0-36 h were(24.55±5.81),(45.50±7.07)and (85.60 ± 13.09)ng·h/ml. In the dose range,cmax,AUC0-36 h h had a linear relationship with dose (R2 were 0.974 5 and 0.968 3). The main pharmacokinetic parameters of low-dose of mildronate with multiple administration after keeping stable were as follows:cmin was(0.28 ± 0.10)ng/ml;AUCs was(38.78 ± 4.18)ng·h/ml;cs was(1.62 ± 0.17)ng/ml;DF was(3.81 ± 1.14);t1/2 was(6.17 ± 1.46)h;tmax was(1.20 ± 0.33)h;cmax was(6.46 ± 1.96)ng/ml;AUC0-36 h was(40.33 ± 4.65)ng·h/ml;accumulation factor of cmax and AUC were(1.73±0.90)and(1.64±0.40). Compared with single administration,t1/2,cmax and AUC of mildronate with multiple admin-istration after keeping stable all changed,and tmax had no signifi-cant difference. After single administration,26 h accumulative excretion rate of those groups were (0.004 009 ± 0.001 1)%, (0.004 026±0.001 01)% and(0.003 858±0.000 68)% respec-tively. CONCLUSIONS:Established method is sensitive,accurate and specific,and suitable for the determination of mildronate concentration in human plasma and urine and pharmacokinetics study. Mildronate capsule shows certain accumulation effect in healthy volunteers,and linear pharmacokinetic characteristics.

Objective To provide new experimental evidences associated with the mechanisms of inhaled anesthetics, the effects of sevoflurane on the electric activities of inhibitory interneurons in basal forebrain area (BF) were observed.Methods C57BL/6 mice, aged 2-3 weeks, were used and BF sections were cut for whole patch-clamp recording.Artificial cerebrospinal fluid containing sevoflurane was given and action potential, inhibitory postsynaptic potential were recorded.Results Sevoflurane could increase the frequency of firing rate of inhibitory interneurons in basal forebrain area (P<0.001), which could increase the frequency of action potential caused by depolarization current (P<0.05), and increase the frequency of spontaneous inhibitory postsynaptic currents of pyramidal neurons (P<0.05), while AP-depended miniature inhibitory postsynaptic currents were not significantly changed.Conclusion The basal forebrain inhibitory interneurons are involved in the anesthetic effect of sevoflurane.

OBJECTIVETo compare robot-assisted laparoscopic radical prostatectomy (RALRP) with laparoscopic radical prostatectomy (LRP) in the treatment of prostate cancer and investigate the clinical application value of RLRP.

METHODSWe retrospectively analyzed 70 cases of prostate cancer treated by RALRP and another 32 cases treated by LRP. We compared the operation time, intraoperative blood loss and transfusion, catheter-indwelling time, postoperative hospital stay, incisal margin positive rate, biochemical recurrence, and normal postoperative urinary continence and penile erectile function between the two groups of patients.

RESULTSAll the operations were successfully accomplished. RALRP exhibited a significant superiority over LRP in intraoperative blood loss and transfusion, catheter-indwelling time, and postoperative hospital stay, urinary continence and erectile function (P < 0.05).

CONCLUSIONRobot-assisted laparoscopic radical prostatectomy, with its advantages of few postoperative complications and well-preserved urinary continence and penile erectile function, is an effective, safe and minimally invasive surgical option for prostate cancer.
