Background and Object: Percutaneous coronary intervention (PCI) on ostial lesions in coronary arteries associated with higher procedural difficulty and complication morbility. It has been technically difficult because it should be done with precise stent placement in ostium and absence of side branch compromise. The Szabo technique consists of side branch wiring through most proximal stent strut as well as main branch wiring through stent lumen. The side branch wire or anchor wire prevents stent advancement beyond ostial segment and makes possible the accurate stent implantation in ostium. The purpose of this study is to evaluate the safety, feasibility and success rate of Szabo technique by analysing technical, angiographic and IVUS (Intravascular Ultrasonography) findings. Methods: The data of 39 PCIs in 39 patients with a significant lesion at a coronary artery ostium which was treated percutaneously using Szabo technique were retrospectively analysed. The technically successful procedure was defined as there was neither stent loss nor second guide wire pull back during stent advancement. A successful procedure from angiographic point of view was defined as a precise stent implantation at ostium without side branch compromise. Successful procedure from IVUS point of view was defined as accurate stent placement in ostium without proximal protrusion and without any stent uncovered area. A total of 39 patients was with 28 males and 11 females. They aged from 43 to 79 years with a mean age of （65±12）years. The 6F and 7F guiding catheter were used in 35 (89.7%) and 4 (10.3%) patients separately. The access was radial in 31 (79.5%) and femoral in 8 (20.5%) patients. The culprit vessel was left anterior descending (LAD) in 26(66.7%), right coronary artery (RCA) 5 (12.8%), circumflex-obtuse marginal (LCX-OM) 3(7.7%), and posterior descending (PDA) 5(12.8%). IVUS was performed through culprit vessel in 30 (76.9%) and was also done in side branch in 9 (23.1%) patients after stent implantation. Results The procedure was technically successful in 36 (92.3%) patients. All technically successful patients had angiographic success (100%). IVUS examination of culprit vessel showed accurate stent placement in ostium 29 (96.7%) and slight stent proximal protrusion in 1(3.3%) patients. No serious complication occured. Conclusions This study shows that Szabo technique is safe and feasible for PCI in ostial coronary artery lesions with a high angiographic success rate，its deserved to spread.

Objective To observe the respiratory system adverse drug reaction ( AREs) in obese patients in anesthesia recovery incidence and treatment outcome .Methods This was a control prospective trial .Study was con-ducted on 27 cases of obesity and the same amount of normal with body mass index (BMI)<30(control group).The sex distribution ,age and the type of operation and operation was similar between the two groups .The hospitalization rate of AREs in PACU was observed .Descriptive analysis on the variables ,use Mann-Whitney U,compared with chi square test and Fisher exact test of variables .The relationship between variables and AREs was studied by using uni-variate and multivariate Logistic retrospective analysis .Results Obese patients with the STOP-Bang≥3 ( 89% vs 11%,P<0.001)occur more frequently,obese patients had a lower rate of underwent high risk operations (7% vs 41%,P=0.005) and big operation (4% v s15%,P=0.008).Obesity in PACU patients were more susceptible to getting AREs(33% vs 7%,P<0.018).Multivariate analysis indicated that obesity and residual muscle relaxation effect was the independent risk factors of AREs .Obese patients in PACU had a longer periods of time treatment (120min vs 84min,P<0.001).Conclusion Obesity is an independent risk factor for PACU in patients with AREs . Obese patients in PACU were treated time more longer .

Objective To explore the clinical characteristics and prognosis of apical hypertrophic cardiomy -opathy (AHCM).Methods A retrospective analysis was performed on the clinical data of 34 patients with AHCM, the clinical characteristic , ECG, imageology data and the cardiovascular morbidity were counted and analyzed . Results There was no specificity on the clinical characteristics of the patients with AHCM ,the high voltage of the left ventricular and the huge inverted T wave of the left precordial leads came into the characteristic change for the ECG,there were 21 patients of the total 34 patients were made a definite diagnosis after examined by the ultrasonic cardiogram,13 patients of them were made a definite diagnosis after examined by MRI .During the following-up,there were 4 patients occurred angiocardiopathy (the morbidity was 11.8%).The thickness of apex,apex cordis and poste-rior wall of the left ventricle examined during the last follow-up had significant differences compared with that during the first diagnosis(t=-3.73,-3.908,all P<0.05).The left ventricular ejection fraction ,interventricular septal thickness,left ventricular end diastolic diameter and thickness of the posterior wall of left ventricle had no significant differences compared with that during the first diagnosis (t =1.762,1.662, -1.857,2.015,all P >0.05). Conclusion AHCM has the benign prognosis effect , but the clinical misdiagnosis rate is high , clinicians should enhance their understanding level on the disease ,the characteristic ECG change ,ultrasonic cardiogram and MRI check can help to make a definite diagnosis .

Objective To review the prenatal ultrasonographic evaluation on fetal midline facial defects of holoprosencephaly. Methods Twenty-four facial malformations of 14 cases with alobar/semilobar holoprosencephaly from August 2000 through April 2004 were reviewed to determine and classify the associated facial abnormalities detected with prenatal sonography. Results There were 24 facial abnormalities in 14 cases with alobar/semilobar holoprosencephaly. Facial abnormalities were present in all cases and were detected in 22 ( 91.7%) of 24 facial malformations on prenatal sonography. One or more extrafacial anomalies were present in 8 ( 57.1%) of 14 fetuses. Conclusions Prenatal sonographic evaluation of midline facial defect may allow more definitive diagnosis of alobar or semilobar holoprosencephaly.

In this experiment, Animal model of guinea pig's experimental Autoimmune sensorineural hearing Loss was established by injecting crud inner ear antigen (CIEAg), Dexamethason was used to tret the deaf guinea pigs for one week, the ABRT(Acoustic Brain—stem Reaction Threshold) of guinea pigs was measured and the morphological change of the guinea pigs inner ear, tissue was observd. We found that the deaf guinea pig's ABRT rose distinctly to 60. 8?5.31 dBspl and inner ear hair cell showed severe damage. The number of the hair cell of the third cochlear turn lost 111?55.8. After one week treatment with Dexamethason,the treated group's ABRT reduced to 48. 8?6. 69dBspl, the number of the outer—hair—cell of the third cochlear turn is only 57. 254?18. The results indicate that Dexamethon has effect on the AISNHL,it can clearly lighten the damage of inner ear tissue and significantly improve the ABRT. The mechanism still remains unknown.

(TNF-?) gene was determined by PCR-RFLP in 54 patients with thyroid-associated ophthalmorpathy (TAO), 60 patients with autoimmune thyroid disease (AITD) without ophthalmopathy and 76 healthy subjects. The results showed that the frequencies of TC+CC genotype and C allele in TAO group, especially in male patients, were significantly higher than those in the other two groups (both P

Objective The deformed nasal bone is commonly seen in clinical practice of plastic surgery, and up to now, there is still lack of systemic classification to direct clinical treatment. Attempt was made in this study to classify the deformed nasal bone and present their plastic surgery treatment. Methods According to the orientation of the nasal bone deviation, the nasal bone deformities were divided into seven types, including the depressed, deviated, combination of the depressed and deviated, convex, widened, shortened ones and others. Of the 78 cases with the deformed nasal bone, 52 cases were corrected by the bone osteotomy techniques, and 26 cases by augmentation rhinoplasty. Results The satisfactory repair outcomes were achieved in 48 nasal bone deformities of the 52 cases (92%), and then secondary procedures were performed in 4 cases for further improvements (8%). Augmentation rhinoplasty in 26 cases showed good results. Conclusions Those types of classification are relatively simple and comprehensive, which is conducive to clinical treatment. The nasal bone osteotomy is effective to repair the deformed nasal bone.
