Objective To investigate the clinical efficacy of kidney-tonifying and blood-activating therapy on puberty polycystic ovarian syndrome(PCOS).Methods Thirty-one PCOS patients were randomly allocated into 2 groups:16 patients(TCM group)received kidney-tonifying and blood-activating Fuke No.5 Prescription combined with herbal medicine based on the menstrual cycle,and 15 patients(WM group)received oral administration of western medicine of diane-35.Changes of clinical symptoms and signs,B-ultrasonic results and serum hormones levels of follicle-stimulating hormone(FSH),luteinizing hormone(LH),prolactin(PRL),testosterone(T)and estrogen(E2)were examined before treatment,after treatment for 3 menstrual cycles and on the 3rd cycle after suspension.Results The menstuation and ovulation,serum sexual hormones(except FSH and E2)levels,and B-ultrasonic indexes(except the volume of uterus)were obviously improved in the two groups after treatment for 3 menstrual cycles(P0.05 compared with those before treatment),but remained at the levels after treatment for 3 menstrual cycles(P

Objective To evaluate the surgical effect for congenital nystagmus (CN) with an abnormal head position in all three axes of a predominant head turn. Design Retrospective case series. Participants 11 patients with horizontal nystagmus and abnormal head position treated in Xingtai Eye Hospital during 2003-2008. All had an abnormal head position in all three axes with a predomi-nant head turn. Methods Recession of the yoke muscles responsible for the slow phase of nystagmus (one medial rectus of 6mm, and one lateral rectus 8 mm), and simultaneously resection of the yoke muscles responsible for the fast phase of nystagmus (the other lateral rectus 9 mm, and medial rectus 7 mm) were performed. The follow-up was from 6 to 20 months. Main Outcome Measures The visual acuity of both eyes in primary position, the degree of head turn, chin elevation or depression, head tilt. Results At the last follow-up, the all 11 patients undergoing the operation for CN gained two or more lines of Snellen acuity with both eyes in primary position for be-ing corrected best. The postoperative mixed head position of 9 cases got disappear or ≤ 10°. Of 1 case developed overcorrection of the head turn. 1 case has the head turn of ≤15°, and 1 case remained the head turn of 25°. Conclusion Recessions and resections of the horizontal yoke rectus muscles in nystagmus with blockage position, when the head turn predominates over the vertical and torsional components, are effective in diminishing the abnormal head position on all three axes, and improve the visual acuity with both eyes in primary position.

Objective To evaluate the role of transeso phageal echocardiography(TEE) before chemical or electric cardioversion for non-vulvular atrial fibrillation. Methods Forty-three patients, confirmed non-vulvular atrial fibrillation, undertook anticoagulation or anti-platelet therapy and transthoracic echocardiography and TEE less than 24-48 hours prior to cardioversion. Results Two thrombi in the left atrial appendage and three spontaneous echo contrasts in the left atrium were evidenced. After anticoagulation or anti-platelet therapy, 39 patients undertook cardioversion therapy. Among them,31 patients received drug cardioversion,success in 19,and failure in 12;8 patients received electric cardioversion,success in 6,and failure in 2. There were no thromboembolic events during the hospitalization. Conclusions TEE performed before cardioversion for atrial fibrillation is necessary to reduce the risks of thromboembolic events and to guide for anticoagulation therapy.

Objective To determine the accuracy and usefulness of dobutamine stress echocardiography(DSE) in detecting restenosis after percutaneous coronary intervention (PCI). Methods DSE was conducted in 47 patients before coronary angiography, 6 months to 18 months after PCI. The standard protocol of DSE was 5,10,20,30 ?g?kg~(-1)?min~(-1) with subsequent incremental increases every 3 minutes to a maximum dose of 40 ?g?kg~(-1)?min~(-1). Consistency of the results was compared between DSE and coronary angiography.Results Compared with coronary angiographic results, DSE had a low sensitivity(64%) but high specificity(86%) for detection of restenosis after PCI. The total accuracy was 72%. Conclusions DSE can assess restenosis after PCI with lower cost and safety.

The use of genetic approaches to probe relative genes that control sensitivity to volatile anesthetics in intact model has recently emerged as the powerful tools and strategies in dissecting mechanisms of anesthesia. Multiple model organisms such as yeast, nematodes, fruitflies and mammals are currently being exploited, and a number of sensitive genes have been screened, with some of them being cloned, located, and function identified. The emerging technologies are likely to provide further great advances for elucidating the specific anesthetic molecular sites.

G1.(3)Among 5 groups,the highest incidences of nausea,vomiting and pruritis were observed in group G1 for about 24% 32%,but with no statistical difference compared with other groups.Conclusion: With equal doses of bupivacaine and fentanyl mixed,the concentration/volume ratios may affect the analgesic effects of postoperative epidural analgesia in patients with hepatectomy.

Objective To study the effect of myocardial infarction induced by distal left ascending artery occlusion on left ventrieular(LV) synchronism. Methods Routine echocardiography and vector velocity imaging were performed within 2 hours before and 7-14 days after myocardial infarction by occluding distal left ascending coronary arteries in experimental pigs. Routine eehocardiographie parameters of LV, including end diastolic and systolic diameters, volumes, and spherical indexes were measured or calculated. Six segmental peak systolic velocity, strain and strain rate were compared between pre- and post-myocardial infarction. Results After myocardial infarction, LV end diastolic, end systolic long diameter and end systolic volume increased with decreased ejection fraction. With the 6 segmental systolic velocity, strain and strain rate significantly reduced,the mean 6-segmental time to peak strain rate delayed significantly. Conclusions Abnormal synchronism after myocardial infarction may aggravate LV systolic dysfunction.

Obiective To observe the value of speckle tracking imaging(STI)in assessing left atrial(LA) function in patients with chronic heart failure(CHF).Methods Twenty-two patients with CHF[LVEF(37.1± 10.5)%]and twenty normal controls[LVEF(61.94±10.68)%]were studied.CHF group was subdevided into patients with normal or abnormal LV filling pressure.Velocity vector imaging(Siemens Medical Solutions)was used to acquire 2-D images at parasternallong axis and apical 4-chamber views.The LA dimension and volume,LV volume and ejection fraction,ratio of mitral valve E wave and mitral annulus velocity e'E/e')were measured. LA tangential and radial velocity(Vt-As,Vr-As)and time to peak velocity(TVt-As,TVr-As)were analysed on Syngo Workplace offline.Results Vt-As and Vr-As of the CHF group were significantly smaller than those of the controls(P＜0.05),and Vr-As was even decreased in patient with elevated LV filling pressure(P＜0.05), however,TVt-AS and TVr-AS didn't show evident impairment in the CHF group(P＞0.05).Vt-As and Vr-AS were closely correlated with LVEF,EDV and ESV(P＜0.05).Vt-As was negtively correlated with LA volume (P＜0.05).Conclusions STI can quickly and accurately assess LA function,and help to recognize patients with elevated LV filling pressure,which is useful in the risk stratification,treatment evaluation and prognosis prediction of CHF patients.
