Objective To explore the clinical significance of urine transferrin testing in the diagnosis of early pregnancy-induced hypertension syndrome (PIH).Methods Sixty-eight PIH patients (PIH group) who received treatment from January 2012 to October 2013 were enrolled in this study.Mild PIH was 21 patients,midrange PIH was 24 patients and severe PIH was 23 patients.Meanwhile,68 cases of healthy person were selected as control group.The level of urine transferrin,urea and creatinine were compared between two groups.Results The level of urine transferrin,urea and creatinine in PIH group were significantly higher than those in control group[(3.01 ± 1.82) mg/L vs.(1.29 ± 0.88) mg/L,(13.12 ± 5.51) mmol/L vs.(6.23 ± 3.68) mmol/L,(135.5 ± 62.3) μ mol/L vs.(85.1 ± 38.2) μ mol/L] (P ＜ 0.05).The sensitivity of urine transferrin,urea and creatinine in mild PIH was 76.19％,61.90％,57.14％.In midrange PIH was 75.00％,79.17％,75.00％.In severe PIH was 78.26％,86.96％,73.91％.The specificity of urine transferrin,urea and creatinine was 80.65％,56.45％,58.06％.The sensitivity of different degree of PIH was exceeded 75.00％.The sensitivity of urine transferrin in mild PIH was significantly higher than urea and creatinine (P ＜ 0.05).But the sensitivity of urine transferrin in midrange PIH and severe PIH had no significant difference (P ＞ 0.05).The specificity of urine transferrin was significantly higher than urea and creatinine (P ＜ 0.05).Conclusions Urine transferrin is a good index in diagnosis of early PIH,which can reflect the early injury degree of the renal tubular and glomerular.It has active and important significance for the clinical diagnosis and treatment of PIH.

Objective To study the method and effect of subcutaneous pedicle flap based on the orbicularis oculi muscle in the treatment of xanthelasma.Methods According to the situation of xanthelasma and the soft tissues of upper eyelid,two new double-folds eyelid was designed.The soft tissues (including the skin and muscle) between two lines were intended to form a subcutaneous pedicle flap based on the orbicularis oculi muscle.Then,after the excision of xanthelasma from the surface of orbicularis oculi muscle,the flap was transferred to the defected site.Finally,a new double-folds eyelid was made.Results 13 cases with 25 sides were treated with a follow-up period of 3-6 months.All flaps were survived with good functions and the appearance of upper eyelids were satisfactory.Conclusions Subcutaneous pedicle flap based on the orbicularis oculi muscle is a reliable option for the treatment of xanthelasma.It has the advantages of abundant blood supply,convenience and effective.

Objective To investigate the onset of left ventricular remodeling (LVRM) after acute myocardium infarction (AMI) and its changes within 6 hours in dogs on echocardiography. Methods AMI was induced in 14 dogs by ligating the left anterior descending arteries. Eight myocardium infarcted models were successful and were sacrified for pathological study. The indices of LVRM: wall infarction thickness (WIT), the wall motion score index (WMSI), left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV) and left ventricular ejection fraction (LVEF) were evaluated before and 1 h, 2 h, 3 h, 4 h, 5 h and 6 h after operation. Results Compared with the pre-operation, WIT and LVEF were decreased (P<0.01), LVESV and WMSI were increased (P<0.01), and LVEDV was increased (P<0.05 or P<0.01) at every time point after operation. WIT had no significant difference at 1 h, 2 h, 3 h, 4 h, 5h and 6h after operation (P＞0.05). LVEDV, LVESV were higher (P<0.05) and LVEF was lower (P<0.05 or P<0.01) at 4 h, 5 h, and 6 h than at 1 h, and 2 h after operation. WMSI was higher at 3 h, 4 h, 5 h, and 6 h than at 1h (P<0.05). Conclusions In our experiment, LVRM occurred at 1 h after AMI in dogs. Thus echocardiography may evaluate early LVRM.

This paper reported a new type of amylase (neoamylase) secreted by a Bacillus strain ZX99. The enzyme was a kind of ectoenzyme that could catalyze starch into isomalto-oligosaccharide effectively, but could not act on pullulan as substrate. The strain Bacillus ZX99 was mutated by ultraviolet ray and a mutant strain BS3.232 was screened. The activity of the neoamylase produced from BS3.232 increased by 60% over that from ZX99 under the same conditions. The results of thin-layer chromatography of products from starch and pullulan catalyzed by the enzyme demonstrated that the enzyme was different from neopullulanase and can be used to produce isomaltooligosaccharide from starch, including isomaltose, panose, isomaltotriose, isomaltotetose.

Objective To evaluate the safety and accuracy of CT-guided cutting needle biopsy for the hepatic lesions near diaphragmatic dome.Methods A total of 25 cases with hepatic lesions near the diaphragmatic dome were undertaken CT-guided cutting needle biopsy using 16 gauge or 18 gauge core biopsy needles.Results Histological examination showed malignancy in 17 cases and benign in 8 with 2 false negative results(8%),and there were no false positive results.The specificities of malignant and benign lesions were 100% and 75%,respectively.Overall accuracy was 92%.Pneumothorax,needle tract hemorrhage,and subcapsular hepatic hemorrhage occurred in 2(8%),1(4%)and 1(4%),respectively.Conclusion CT-guided cutting needle biopsy for the hepatic lesions near diaphragmatic dome is a reliable and relatively safe diagnostic method.(J Intervent Radiol,2007,16:838-840)

Objective To evaluate the value of echocardiography in diagnosing infective endocarditis (IE) in children. Methods The shape, size, echogenicity, distribution of vegetations and valvular function of the heart were observed by transthoracic echocardiography (TTE) in 30 patients with suspected IE. We correlated TTE ifndings with the results of hemoculture and serologic test. Results Vegetations were observed in all patients by echocardiography:seven patients with tricuspid valve vegetations, two with mitral valve vegetations, three with pulmonary valve vegetations, three with main pulmonary artery vegetations, three with aortic valve vegetations, two with aortic valve abscess, and two with vegetations in right atrium. After anti-infection therapy, the size of vegetations in iffteen patients became smaller and the less echogenic than before. Vegetations disappeared in two patients. Vegetation was recurrent repeatedly in one case. Ten patients recovered after operation. Two severe cases died. Five patients underwent TTE again one week after the previous negative TTE. Of them, echocardiography demonstrated vegetations in three cases. However, no vegetations were found in rest two cases because antibiotics had been used at early stage. In addition, echocardiography demonstrated one patient with mitral valve vegetation. But the lesion was ifnally conifrmed to be operating suture. The sensitivity and specificity of TTE in detecting vegetations were 88.0% and 80.0%, respectively. Blood cultures were positive in twenty-seven cases and were negative in three cases. Conclusions The early diagnosis of IE is important to improve patient′s prognosis. It takes a long time in organism cultivation before achieving the clinical diagnosis. TTE can help obtain an early diagnosis stage of IE, and provide the assessment of size and location of vegetation. It plays an important role in treatment and prognosis prediction.
