Objective To investigate the value of high-dose dobutamine stress echocardiography combined with two-dimensional strain imaging in early diagnosis of coronary artery disease. Methods Highdose dobutamine stress echocardiography was performed to 28 patients with suspected coronary artery disease. All wall movements were observed during resting condition and at all stress levels,respectively;the peak systolic longitudinal strain in each endomyocardial segment of left ventricular was measured; the sensitivity and specificity between visual method and two-dimensional strain imaging in diagnosing myocardial ischemia with high-dose dobutamine stress echocardiography were compared. The average peak systolic longitudinal strain was calculated against control group, coronary artery disease group during ischemia segments and non-ischemia segments, and a comparison was made inside each group as well as against the other groups. The area under receiver operating characteristic curve of the peak systolic longitudinal strain was used to predict the sensitivity and the specificity of myocardial ischemia. Results With dobutamine dose of 40 μg·kg-1 · min-1 ,wall motion abnormalities were diagnosed in 6 patients (20 segments) through visual method, myocardial ischemia was found in 15 patients (148 segments) through computing the peak systolic longitudinal strain. Inside the coronary artery disease group during ischemic　segments,the majority of peak systolic longitudinal strain was significantly reduced ( P＜0.05) compared to the non-ischemic segments and the control group. In diagnosing myocardial ischemia in high-dose dobutamine stress echocardiography, the sensitivity of visual method and two-dimensional strain imaging were 35.3％ and 88.2％(P＜0.01), specificity 100％ and 100％(P＞0.05), and accuracy 60.7％ and 92.8％ (P＜0.01). The cutoff value of the peak systolic longitudinal strain was less than or equal to 14.9％, its sensitivity and specificity in predicting myocardial ischemia were 83.3％ and 91.7％,respectively. Conclusions High-dose dobutamine stress echocardiography combined with two-dimensional strain imaging can increase the sensitivity of detecting myocardial ischemia and detect concealed myocardial ischemia. High-dose dobutamine stress echocardiography combined with two-dimensional strain imaging can be used in early diagnosis of coronary artery disease.

OBJECTIVETo observe the clinical effect of Rebixiao granule (RBXG) in treating repeatedly attacking acute gouty arthritis and through experimental study on blood uric acid to explore RBXG's therapeutic mechanism.

METHODSNinety repeatedly attacking acute gouty arthritis patients were divided into the treated group (n = 60) and control group (n = 30). The treated group was treated with RBXG, and the control group was treated with Futalin tablets (diclofenac sodium). The baseline treatment including good rest, low purine diet, sufficient water drinking and urine alkalization, etc. was then given to both groups. Hypoxanthine 600 mg/kg and niacin 100 mg/kg was applied to hyperuricemic mice by gastrogavage to establish the animal models.

RESULTSThe clinical effective rate of the treated group was 95.0% and that of the control 90.0%. Good therapeutic effects were won, insignificant difference (P > 0.05)was shown between the two groups. However, the cure rate of the treated group was 26.7% while that of the control group was 10.0%, with significant difference (P < 0.01) shown between them. The treated group had its blood uric acid lowered, which was significantly different (P < 0.05) from that of the control group. The animal experiment indicated that all the three groups treated with different dosages of RBXG, as well as the Ash bark and Smilax glabra rhizome groups had their blood uric acid content reduced in the hyperuricemic mice.

CONCLUSIONRBXG has a quicker initiation and better treatment effects than sole anti-inflammatory and analgesic agents on the treatment of repeatedly attacking acute gouty arthritis, showing no obvious toxic or adverse reactions and therefore good for long-term administration and likely to be a safe TCM preparation to control the symptoms and reduce the onsets of repeatedly attacking of acute gouty arthritis. The animal experiment shows that both the compound preparation and part of the single ingredients in the recipe have the function of reducing blood uric acid. However, the compound recipe has better therapeutic effects, proving to be superior to single drugs.

Conclusion The comprehensive imaging data are helpful in the localized diagnosis of PA.Correct preoperative qualitative diagnosis of APA is the key step for the surgical treatment for PA.

OBJECTIVETo evaluate the efficacy and safety of long-term on-demand use of vardenafil in the treatment of erectile dysfunction (ED).

METHODSWe conducted a questionnaire investigation among 891 ED patients treated by on-demand use of oral vardenafil at 20 mg every 3 days from March 2007 to January 2010, covering the general information of the patients, their need for and attitudes towards the treatment, clinical efficacy and adverse events of the drug, and satisfaction of the patients and their partners after 12 weeks of treatment.

RESULTSTreatment and follow-up were completed in 700 patients, of whom 504 (72%) achieved sufficient hardness and duration of penile erection and overall sexual satisfaction, 84 (12%) admitted to improvement of erectile hardness and duration but not adequate satisfaction, and the other 112 (16%) experienced no significant changes. Significant differences were found in IIEF-5 scores, Rigiscan test results and partners TSS scores before and after the treatment (P < 0.05). Most frequent adverse events included flushing (15%), dizziness and headache (10%), dyspepsia (3%), and nasal congestion (1%).

CONCLUSIONLong-term on-demand use of oral vardenafil, in addition to its safety and good tolerance, can effectively improve the erectile function of ED patients, their success rate of sexual intercourse, and overall quality of sexual life.

OBJECTIVETo compare the regulatory effects of electro-acupuncture (EA) at acupoints Zusanli (ST36) and Hegu (LI4) on the visceral hyper-sensitivity in the rat model of irritable bowel syndrome (IBS), and to explore the acting targets and specialty of acupoints.

METHODSExcept 8 rats of the normal control group, the rest 32 rats were prepared to set up the IBS models. IBS animal model was prepared by enema with acetic acid. Model rats were divided into three groups. Except for rats in the model group for control, those in the other two groups were treated 20 min by EA on ST36 (EA-ST36) and LI4 (EA-LI4) respectively for 2 weeks to observe the effect on behavior response of viscera sensitivity. The changes of neuropeptide (NPY), the somatostatin (SS) levels in blood and tissues of brain and intestine were monitored as well.

RESULTSThe volume thresholds for abdomen uplifting and back hunching were obviously increased after EA-ST36 (P<0.05), but showed insignificant change after EA-LI4. NPY contents lowered and SS contents increased in model rats; both EA-ST36 and EA-LI4 could raise the level of thalamic NPY (P<0.01 and P<0.05, respectively), but showed insignificant effects on NPY in colonic tissue. As for SS content, its colonic level could be reduced by EA-S36 and EA-LI4 (P<0.01 and P<0.05, respectively), however, its blood level was affected only by EA-ST36 (P<0.05).

CONCLUSIONSEA-ST36 or EA-LI4 could regulate the NPY in thalamus and SS in colonic tissue, the former could affect blood level of SS as well. It is deemed that NPY and SS may be the key substances for regulating the action of acupuncture in the brain-intestinal axis; their different levels could be regarded as an indicator for the functional difference between the acupoints.

OBJECTIVETo observe the safety and efficacy of tadalafil in the treatment of erectile dysfunction in clinical research.

METHODSEighty patients with ED, before and after 20 mg tadalafil administered orally, received respectively the rigiscan examination with aural and visual sexual stimulation at the same time, and then Bphallic circumference variation, stiffness index, duration were compared before and after the treatment.

RESULTSPhallic stiffness index, duration revealed a statistically (P < 0.05) obvious improvement before and after the treatment for all patients. A significant difference (P < 0.01) on the phallic stiffness index, duration were found between the patients with psychogenic ED and others with organic or mixed ED after the treatment. Overall satisfaction with tadalafil was 82.5%. There was an obvious difference on the curative rates between the patients with psychogenic ED (92.3%) and others with organic ED (68.7%) or mixed ED (58.3%). All adverse events (11 cases of headache and dizziness, 8 cases of digestive canal unwell, 5 cases of flushing, 2 cases of back muscle pain) associated with tadalafil were mild and recovered without any treatment.

CONCLUSIONTadalafil improves erectile function significantly in most patients. Adverse reactions are generally transient and mild to moderate in nature.
