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.

Objective:To explore the clinical characteristics of senile degenerative valvular heart disease (SDHVD)compli-cated heart failure (HF).Methods:A total of 68 SDHVD + HF patients were enrolled as SDHVD + HF group,another 62 aged HF patients without valvular calcification in the same period were enrolled as HF control group.Characteristics of two groups were analyzed.Results:Compared with HF control group,there were significant rise in percentages of severe cardiac dysfunction (NYHA class III:19.35% vs.38.24%,NYHA class IV:35.49% vs.55.88%),incidence rates of at-rial premature (17.74% vs.38.24%),sinoatrial block (22.58% vs.50.00%),atrial fibrillation (27.42% vs.52.94%), paroxysmal atrial tachycardia (30.65% vs.48.53%),atrioventricular block (33.87% vs.52.94%)and bundle branch block (25.81% vs.48.53%)in SDHVD + HF group,P <0.05 or <0.01. Conclusion:When SDHVD patients compli-cate with HF,the HF degree aggravates and incidence rate of arrhythmia rises.

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 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.

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 investigate the application effect of case-based learning (CBL) in clinical practice teaching of cardiothoracic surgery.Methods:A total of 86 interns who rotated in our department from February to November 2019 were randomized into observation group ( n = 43) and control group ( n = 43) by drawing lots. The control group used traditional teaching method, and the observation group used CBL teaching method. The differences between the two groups in professional theoretical performance, clinical skill achievement and teaching satisfaction were compared. Results:The professional theoretical scores, clinical skills scores, and teaching satisfaction of the observation group were better than those of the control group, with statistical differences ( P < 0.05). Conclusion:The CBL teaching method can effectively help interns master professional theoretical knowledge and clinical practice skills of cardiothoracic surgery, which has obtained satisfactory teaching results and is worthy of promotion.
