Objective To investigate the diagnostic value of postexercise systolic blood pressure(SBP) response in detecting coronary artery disease(CAD) in patients with electrocardiographic left ventricular(LV) hypertrophy.Methods Acording to their results of selective coronary angiography,58 patients with electrocardiographic LV hypertrophy were divided into group 1(27 patients without significant coronary lesions) and group 2(31 patients with significant coronary lesions).Symptom-limited treadmill exercise testing was conducted in those patients.Results The SBP ratio(SBP at 3 minutes of recovery divided by SBP at peak exercise) was significantly higher in group 2 than in group 1(0 98?0 11 vs 0 84?0 11,P

Objective To establish bladder reflex arc with sensory afferent pathway using SD rats,and evaluate its effect in the treatment of atonic bladder after spinal cord injury.Methods Twenty-four male SD rats were used in the study.For each rat,the right side was the experimental side,and the left side was the control side.In the right side,the L5 ventral root (VR) was anastomosed to S2 VR,and the distal end of S2 dorsal root (DR) was anastomosed to the proximal end of L5 peripheral process of dorsal ganglion.In the left side,no treatment was done.In order to evaluate the validity of the bladder reflex arc,general observation,neuro-electrophysiological test and wheat germ agglutinin horseradish peroxidase (WGA-HRP) method were used before and after the spinal cord destruction between L6 and S2 level at 3 months postoperatively.Results Twenty-one rats survived 3 months after the operation,and anastomotic nerves were separated successfully only in seven rats.Compound action potentials (CAPs) of plexus vesica and compound muscle action potentials (CMAPs) of bladder smooth muscle were found by electrical stimulation in distal end of the anastomotic stoma of the right S2 DR.There was no statistically significant difference in action potential before and after paraplegia.No action potential was detected in control sides after paraplegia.The curves of CAPs and CMAPs in the right side were similar to those in the control side,and the mean maximum amplitude reached respectively 71.9％ and 82.4％ of those in the left side before paraplegia.In addition,WGAHRP labeled cells were observed in L5 anterior horn and posterior horn in the experimental side after WGAHRP injection.Conclusion Reconstruction of bladder reflex arc with sensory afferent pathway can promote axonal regeneration of motor and sensory nerves,and then the regenerated axon could contact with cells in anterior and posterior horn of spinal cord through parasympathetic nerves,ultimately the capability of axoplasmic transportation could be reestablished.Therefore,this method can be used for treating atonic bladder.

Objective:To assess the efficacy and safety of electroacupuncture (EA) at Houxi (SI 3) in treating acute lumbar sprain. Methods: Randomized controlled trials (RCTs) involving EA at Houxi (SI 3) for acute lumbar sprain were retrieved from PubMed (1966-2014), EMBASE (1980-2014), Cochrane Library (Issue 1, 2014), CQVIP Database (1989-2014), Wanfang Digital Journal (1998-2014), the Chinese Biological Medical Literature Database (CBM, 1978-2014), and China National Knowledge Internet (CNKI, 1979-2014). The collection of data also adopted hand-search of the relevant journals from the Library of Shanghai Jiao Tong University. All of the data were first evaluated and extracted by two reviewers independently with a specially designed form. Then, the available data were analyzed by the Cochrane Collaboration's RevMan 5.2.0 software. Results:A total of 6 trials involving 1 288 patients were eligible. Meta-analysis showed that the total effectiveness rate in the EA group was significantly different when compared with Nimesulide [RR=1.33; 95% CI (1.19 to 1.49)] and Mobic [RR=1.08; 95% CI (1.03 to 1.14)], but similar to that of acupuncture at Yaotongdian (EX-UE 7) [RR=71.09; 95% CI (1.00 to 1.19)] and Diclofenac Sodium [RR=1.08; (95% CI 0.96 to 1.21)]. The recovery rate in the EA group was significantly different when compared with Mobic [RR=1.67; (95% CI 1.45 to 1.92)] and Nimesulid [RR=1.37; (95% CI 1.15 to 1.62)], but similar to that of acupuncture at Yaotongdian [(RR=1.35; 95% CI 0.99 to 1.84)] and Diclofenac Sodium [(RR=1.19; 95% CI 0.88 to 1.61)]. Conclusion:Up to the search date, there are few high quality RCTs to evaluate the clinical efficacy of EA at Houxi (SI 3) for acute lumbar sprain, especially studies in English. Yet EA at Houxi (SI 3) still appeared to be an efficacious method for acute lumbar sprain, despite several inherent defects of the included studies. Further large scale trials are required to define the role of EA at Houxi (SI 3) in the treatment of this disease.

ObjectiveTo investigate the effect of sivelestat sodium on the prognosis in patients with acute lung injury (ALI) and acute respiratory distress syndrome (ARDS).Methods Databases including PubMed, EBSCO, Springer, Ovid, Wanfang data, CNKI and China Biology Medicine (CBM) were searched to identify randomized controlled trials (RCTs) regarding sivelestat sodium treatment for ALI/ARDS published from 1985 to December 2014. The patients in treatment group received intravenous infusion of sivelestat sodium, and those in control group received normal saline. The items for analysis were 28-day mortality, duration of mechanical ventilation, length of intensive care unit (ICU) stay, and oxygenation index on day 3. According to the evaluation method of Cochrane system, data extraction and quality assessment from the literature were carried out. Meta-analysis was performed using RevMan 5.3. The publication bias was analyzed with funnel plot.Results Five RCTs with a total of 780 participants were included, with 389 patients in sivelestat sodium group, and 391 in control group. Meta analysis showed: compared with control group, sivelestat sodium could not lower the 28-day mortality [odds ratio (OR) = 0.91, 95% confidence interval (95%CI) =0.66-1.26,P = 0.58], or shorten the duration of mechanical ventilation or length of ICU stay [duration of mechanical ventilation: mean difference (MD) = -0.02, 95%CI = -0.29 to 0.24,P = 0.87; length of ICU stay:MD = -9.63, 95%CI =-23.34 to 4.08,P = 0.17], but it could improve oxygenation index on day 3 (MD = 0.88, 95%CI = 0.39 to 1.36, P = 0.000 4). Heterogeneity was not significant for the main analysis and no publication bias was shown on funnel plot. Conclusion Sivelestat sodium gave rise to a better oxygenation on day 3, but did not change the length of mechanical ventilation and ICU stay, and it did not improve 28-day mortality in ALI and ARDS.

Object To study the pharmacokinetics of cinnamic acid in BAOXIN PILL * in rat. Methods Plasma concentration of cinnamic acid was determined by HPLC under the following conditions: column: Hypersil ODS C 18 (150 mm?4.6 mm, 5 ?m); column temperature 30 ℃; mobile phase methanol-1% acetic acid (45∶55); flow rate 0.5 mL/min; detection wavelength 273 nm; aliquot injected 10 ?L. Results A method for the determination of plasma cinnamic acid concentration by HPLC was established. Regression equation of cinnamic acid peak area (Y) and plasma concentration (X) was found to be: Y= 4 973.534 8 +42 867.96 678 X; correlation factor r=0.999 8; rate of cinnamic acid recovery from plasma=97.50% and RSD=1.33%; detection limit=0.15 ng; minimal dectable concentration in rat plasma=75 ng/mL. Absorption pattern of cinnamic acid after ig does showed linearity, corresponding to a first order absorption and elimination of open chamber model. The t 1/2 (K a)=7.12 min; t max =53.29 min, C max =0.20 ?g/mL, and t 1/2 (Ke)=340.74 min. Conclusion The pharmacokinetic parameters obtained in this study may be attributed to the combined action of cinnamic acid and other constituents in the compound preparation of BAOXIN PILL.

Objective To analysis the activity of transcriptional factors in endometrial cancer cell lines with different estrogen receptor subtypes. Methods The mRNA levels of estrogen receptor (ER) was detected by quantitative RT-PCR , and the activity of transcriptional factors was also analysed by 345-channel protein/DNA array in RL-952 ( the expression status of ERα and ERβ both positive), HEC-1A [ERα(±),while ERβ negative] and HEC-1B (ERα and ERβ both negative). The transcription factors of NFkBp65 and p38MAPK with different activity were tested by enzyme-linked immunosorbent assay(ELISA) to confirm the results of protein/DNA array. Results The mRNA levels of ERα in RL-952, HEC-1A and HEC-1B were (6780±282 ), ( 684±84 ) and ( 168±38 ) eopy/ng, respectively. Among 345 candidate transcriptional factors, there were 28 factors associated with ER status. Compared with RL-952 cells, 13 transcriptional activity factors were concomitandy up-regulation, while 15 concomitantly down-regulation in HEC-1A and HEC-1B cells. Transcriptional activities of TrF (1)-1, NRF-1, TCE were significantly correlated with the high-expression status of ERα mRNA ( r =0.523, P=0.037 ), while RFX123 and Ikaros were signitleanfly correlated with the low-expression status of ERα mRNA ( r=-0.312, P=0.041 ). Conclusion Transcriptional factors of TTF(1)-1, NBF-1, TCE may be associated with ER-mediated signal pathway, while RFX123 and Ikaros may be associated with non ER-mediatecl signal pathway in endometrial cancer.

ObjectiveTo investigate the efficacy of meridian differentiation-based point selection plus qi-guiding acupuncture in treating lumbar intervertebral disc herniation.MethodFive hundred and forty-nine patients with lumbar intervertebral disc herniation were randomly allocated, using a random number table, to two groups. The treatment group of 280 patients received qi-guiding acupuncture at points selected according to meridian differentiation and the control group, electroacupuncture at points selected according to meridian differentiation.ResultThe total efficacy rate was 87.5% in the treatment group and 86.6% in the control group; there was no statistically significantdifference between the two groups (P>0.05). The cure rate was 51.8% in the treatment group and41.6% in the control group; there was a statistically significant difference between the two groups (P<0.05). ConclusionThe total efficacy rate of qi-guiding acupuncture at points selected according to meridian differentiation for lumbar intervertebral disc herniation is similar to that of electroacupuncture at points selected according to meridian differentiation, but the cure rate of the former is higher thanthat of the latter.

Objective: To observe the efficacy of acupoint selection by meridian differentiation plus qi-guiding needling in treating lumbar disc herniation (LDH).
Methods: By using the random number table, 549 patients with LDH were randomized into two groups. Two hundred and eighty participants in the observation group were intervened by selecting acupoints by meridian differentiation associated with qi-guiding needling method, and the other 269 participants in the control group were by selecting acupoints by meridian differentiation plus electroacupuncture. At the end of intervention, the changes of conduction velocities of the common peroneal nerve, superficial peroneal nerve, and tibial nerve were observed, and the therapeutic efficacies were compared.
Results: The total effective rate was 87.5% in the observation group versus 86.6% in the control group, and the difference was statistically insignificant (P>0.05). The recovery rate was 51.8% in the observation group versus 37.2% in the control group, and the difference was statistically significant (P<0.05).
Conclusion: Selecting acupoints by meridian differentiation associated with qi-guiding needling can produce a similar total effective rate to selecting acupoints by meridian differentiation plus electroacupuncture, while its recovery rate is comparatively higher.

Objective:To study the variation of recent bladder function of the patients who received radical hysterectomy and evaluate its significance. Methods:Sixty-three patients with cervical carcinoma in International Federation of Gynecology and Obstetrics(FIGO) stage IB1 to ⅡA received urodynamic examination before and after operation. The urodynamic parameters included filling cystometry, pressure-flow rate, and electromyography of sphinctienter. Results:Radical hysterectomy induced significant increase in the first sensation (P<0.01)and post voiding residual of bladder (P<0.01) ;whereas caused significant decrease in the maximum volume(P<0.01), compliance(P<0.01),maximum flow rate(P<0.01) and the pressure at the maximum flow rate(P<0.01), respectively, compared with the corresponding values before the operation. Short-term bladder dysfunctions were observed in 34 patients (54.0%) including bladder detrusor dysfunction, low compliance bladder, bladder outlet obstruction, dyssynergia of urethral external sphincter and detrusor overactivity. The incidences of low compliance bladder and bladder detrusor dysfunction increased significantly after operation (P<0.01). Urinary retention was found in 28.6%(18/63) patients. The incidences of bladder detrusor dysfunction (66.7% vs 20.0%) and detrusor overactivity (33.3% vs 4.4%) in the group with urinary retention were significantly higher than those of corresponding group without urinary retention. Conclusion:The bladder function had obvious short-term changes following radical hysterectomy. In the many types of bladder dysfunction the main dysfunctions were low compliance bladder and bladder detrusor dysfunction. The bladder detrusor dysfunction might be the major cause of the urinary retention following the surgery. Urodynamic test was important for post-operative analysis and treatment of bladder dysfunction.
