3D ultrasound reconstruction in 63 cases of the solid space occupying lesions of liver was reported.Among them,there were 34 primary liver cancer,20 liver metastases and 9 cases hamangioma.By 30 imaging,the internal structure of the tumor could be visualized in 71%(45/63); the relation of the tumor to the surrounding vessels was apparent in 65%(41/63); the margin of the tumor could be outlined in 56%(35/63).The vesucts indicate that 3D ultrasound is superior to conventional 2D sonography to show more accurately the space localization,internal structure and morphology of the lesion thus provides meaningful imaging diagnostic evidences clinicaly.

Zebrafish is widely used as a model organism in the process of drug discovery. It expresses drug metabolizing enzymes like cytochrome P450 (CYP450), uridine 5'-diphospho-glucuronosyltransferase (UGT) and nuclear receptors like pregnane X receptor (PXR), aryl hydrocarbon receptor (AHR), etc. This article summarized the profiles of main drug metabolizing enzymes and nuclear receptors, and reviewed the advances on xenobiotics metabolism in zebrafish.

Objective To explore the correlation between HBV-DNA and serum HBV markers quantitative detection and determine its diagnosis value in hepatitis B virus infection. Methods The HBV-DNA was measured by fluorescence quantitative PCR and hepatitis B virus was detected by time-resolved fluorescence immunoassay (TRFIA). The relationship between the two tests was analyzed statistically using software. Results Detection of HBV-DNA in the peripheral blood of patients with HBsAg (+), HBeAg (+), HBcAb ( + ) showed 92. 9% (79/85) positive rate,and the average DNA copy number was (4.31 ± 1.64) × 106 copies/ml. While the detection of HBV-DNA in the peripheral blood of patients with HBsAg ( + ), HBeAb ( + ), HBcAb ( + ) showed 47.7% (105/220) positive rate, and the average DNA copy number was (2.47 ± 2. 21 ) × 104 copies/ml. In normal controls,blood HBV-DNA detection was negative. Furthermore, HBV-DNA copy number correlated positively with HbeAg quantitation (r = 0. 59, P = 0. 041 ). However, we found no significant correlation between HBV-DNA copy number and HbsAg quantititation (r = 0.221, P = 0.077). Conclusions Different HBV-M had diverse correlation with HBV-DNA number, comprehensive detection of them would be better to assist clinical diagnosis and evaluate the response to treatments.

Uncoupling protein 2(UCP2)is a proton transporter which presents in the mitochondrial inner membrane. Recent studies have found that UCP2 plays important roles in protecting mitochondria functions,re-ducing mitochondrial ROS generation by inducing proton leak across the inner mitochondrial membrane and pro-moting mild uncoupling which leading to a decrease in the mitochondrial inner membrane′s potential. Because of its antioxidant function,UCP2 has been studied in several domains. This review provides novel insights into the molecular mechanisms,by which the activity of UCP2 is regulated and describe novel findings concerning basical experiments of UCP2.

Forty patients with hip disease who underwent first total hip arthroplasty (THA) in Department of Orthopedics, Second Hospital of Chongqing Medical University from January 1999 to January 2002 were selected. They were treated with cemented (n =16) and cementless THA (n =24). The time to leave bed of cemented-THA group was obviously shortened compared with cementless THA group (P

Objective To explore the clinical features and urgent treatment strategies of open stabbing and penetrating wound of the heart. Methods In recent five years, 22 cases of cardiac trauma patients were sent to our emergency department, among them 19 sustained penetrating wounds produced by sharp instruments, 3 with perforating wounds, produced by firearm in 2 and sharp instrument in one. Emergent thoracotomy was performed in all the patients. The injury involved right auricle in 4, left auricle in 1, right ventricle in 11, left ventricle in 3, and perforating wounds of both right and left ventricles in 3 patients. Results Among them 19 survived, and their cardiac and pulmonary recovered 2 weeks after the operation. Three patients with injury of the great vessel died, one of them died 8 hour after the operation. Conclusion When the patients who presented open wounds on the anterior or posterior chests, showing a low or undetectable blood pressure, which could not raised even with fluid resuscitation with two venous lines or in some of them displaying signs of Beck's triad, open cardiac injury should be seriously suspected, and emergent thoracotomy should be taken in order to rescue the patients.

Objective To summarize the incidence, diagnosis, treatment and prognosis of patients with hemolysis, elevated liver enzymes and low platelet count (HELLP) syndrome. Methods The clinical data of fourteen cases with HELLP syndrome complicated by severe pregnancy-induced hypertension were analyzed retrospectively during the past seven years. Results The incidence of HELLP syndrome was 8% in the patients with severe pregnancy-induced hypertension. According to the diagnosis criteria used by Tennessee University, there were eight cases with complete HELLP syndrome and six cases with partial HELLP syndrome. The major therapeutic way were intensive maternal and fetal monitoring, active management of preeclampsia and eclampsia, administration of corticosteroids and termination the pregnancy as fast as possible. The major complications were DIC, placental abruption, pneumonedema and acute renal failure. The maternal and perinatal mortality were 7% and 29%, respectively. Conclusions HELLP syndrome was a serious life-threatening complication of severe pregnancy- induced hypertension. In order to decrease the maternal and perinatal mortality rate, HELLP syndrome should be diagnosed and treated as fast as possible.

Objective To compare the outcomes of 23G and 25G plus (25G+) vitrectomy in treatment of proliferative diabetic retinopathy (PDR).Methods This is a prospective randomized study.Fifty-seven PDR patients (75 eyes) with symptoms requiring vitrectomy were randomly divided into 23G vitrectomy group (30 patients,39 eyes) and 25G+ vitrectomy group (27 patients,36 eyes).Visual acuity,intraocular pressures,ophthalmoscopy,B-scan ultrasound was examined before surgery.The follow-up period was 10.0 (23G group) and 8.5 months (25G+ group) respectively.Intraoperative complications,operation time,postoperative visual acuity,intraocular pressure,postoperative complications and postoperative ocular conditions were analyzed.Results The mean surgical times were (53.35± 7.42)minutes and (49.16±5.17) minutes in 23G and 25G+ group respectively,and the difference was significant (t=4.37,P＜0.05).Iatrogenic injuries occurred in 11 eyes (28.21％) and 5 (13.89％) eyes in 23G and 25G + group respectively,and the difference was significant (x2 =4.93,P＜0.05).The postoperative visual acuity of 23G and 25G+ group were improved compared to before surgery (x2=16.81,18.29; P＜0.05).At last follow-up,there was 25 eyes and 24 eyes with visual acuity ≥ 0.05 in 23G and 25G+ groups respectively,and the difference was not significant (x2 =0.13,P＞0.05).Hypotony was detected in 7 and 3 eyes at the third postoperative day in 23G and 25G+ group respectively,and the difference was significant (x2 =5.67,P＜0.05).Conclusion 25G+ vitrectomy is a safe and effective treatment for PDR with shorter surgery time and fewer surgical complications.

Objective To investigate serum cancer antigens (CA) 125 expression in different types of ovarian endometriosis and related factors.Methods A total of 182 patients with ovarian endometriosis was collected,then they were divided into two groups:ovarian endometriosis combined with other parts of lesions (A group,88 cases),simple ovarian endometriosis group (B group,94 cases).And selected 100 healthy physical check-up women from the hospital outpatient department were as control group.The serum level of CA125 was detected.The patients' information including body shape,menstrual factors,reproductive activities and disease staging were collected.Chi-square criterion and multivariate binary Logistic regression analysis were completed.Results The serum levels of CA125 in A group,B group and control group were (48.64 ± 33.18),(41.35 ± 23.46),(22.16 ± 13.73) kU/L,respectively,and the positive expression rate of three groups were 64.77％ (57/88),52.13％ (49/94),2.00％ (2/100),respectively,there were significant differences (P ＜ 0.05).The multivariate binary Logistic regression analysis result showed that age of 35-49years,reforming American fertility society of Ⅲ-Ⅳ stage,pelvic adhesion and menorrhalgia were the important factors of positive expression of CA125.Conclusion The serum level of CA125 can be used as the evaluation of the diagnosis and treatment of ovarian endometriosis.
