Objective To study the diagnostic techniques of acute anuria caused by upper urinary tract obstruction. Methods Fifty-eight patients with acute anuria caused by upper urinary tract obstruction were analyzed on clinical manifestations,etiology of obstruction and imageologic findings. Results The main clinical manifestations consisted of anuria in 58 cases,pain in renal region in 41,percussion tenderness over kidney region in 33,hypertension in 20,high levels of BUN and creatinine in 57 and hyperkaliemia in 8.The main adjuvant examinations included MRU,B-ultrasound,X-ray (KUB,IVU and retrograde pyelography),CT and MRI.The detection rates of upper urinary tract obstruction by above-mentioned examinations were as follows:100% (25/25) with MRU,88% (50/57) with B-ultrasound,60% (6/10) with CT/MRI,49% (19/39) with X-ray. The detection rates of MRU and B-ultrasound were significantly higher than those of X-ray and CT/MRI (P

Post competency-based medical education complies to the development and philosophy of modern medicine. This paper completely illustrates how to construct a scientific and diversified assessment evaluation system guided by post competency for medical students which combines formative assessment and summative assessment. Through the objective measurement and timely feedback of various abilities of medical students, the closed-loop feedback system of assessment and evaluation can be constructed to guide the exploration and practice of teaching process in reverse.

Prostate cancer is one of the most common male malignancies in many parts of the world and also the fifth leading cause of cancer death among men worldwide.At present,the commonly used clinical screening methods for prostate cancer are serum prostate-specific antigen(PSA)and transrectal ultrasound guided puncture biopsy.However,the above two diagnostic methods have some related problems such as over-diagnosis caused by false negative and false positive.Metabolomics is an important component of systems biol-ogy,which recognizes minor changes in certain molecular metabolites during tumorigenesis and development.This article reviewed how to use the method of metabolomics to find the metabolites of the three major sub-stances in the patients with prostate cancer and the changes of related metabolic pathways to provide the new ideas for the clinical diagnosis of prostate cancer.

Although oxymatrine (OMT) has been shown to directly inhibit the replication of hepatitis B virus (HBV), limited research has been done with this drug. In the present study, the antiviral effect of OMT was investigated in an immunocompetent mouse model of chronic HBV infection. The infection was achieved by tail vein injection of a large volume of DNA solution. OMT (2.2, 6.7 and 20 mg/kg) was administered by daily intraperitoneal injection for 6 weeks. The efficacy of OMT was evaluated by the levels of HBV DNA, hepatitis B surface antigen (HBsAg), hepatitis B e antigen (HBeAg) and hepatitis B core antigen (HBcAg). The immunoregulatory activity of OMT was evaluated by serum ELISA and flow cytometry. Results shows that OMT at 20 mg/kg inhibited HBV replication, and it was more efficient than entecavir (ETV) in the elimination of serum HBsAg and intrahepatic HBcAg. In addition, OMT accelerated the production of interferon-(IFN-) in a dose-dependent manner in CD4T cells. Our findings demonstrate the beneficial effects of OMT on the enhancement of immunological function and in the control of HBV antigens. The findings suggest this drug to be a good antiviral therapeutic candidate for the treatment of HBV infection.

BACKGROUND: Coronary artery disease (CAD) is the commonest cause of heart failure (HF), whereas pulmonary hypertension (PH) has not been established or reported in this patient population. Therefore, we assessed the prevalence, risk factors, and survival in CAD-associated HF (CAD-HF) complicated with PH. METHODS: Symptomatic CAD-HF patients were continuously enrolled in this prospective, multicenter registry study. Echocardiography, coronary arteriography, left and right heart catheterization (RHC), and other baseline clinical data were recorded. Patients were followed up and their survival was recorded. RESULTS: One hundred and eighty-two CAD-HF patients were enrolled, including 142 with HF with a preserved ejection fraction (heart failure with preserved ejection fraction [HFpEF]; left ventricular ejection fraction [LVEF] ≥50%) and 40 with a reduced ejection fraction (heart failure with reduced ejection fraction [HFrEF]; LVEF < 50%). PH was diagnosed with RHC in 77.5% of patients. Patients with PH showed worse hemodynamic parameters and higher mortality. HFrEF-PH patients had worse survival than HFpEF-PH patients. CAD-HF patients with an enlarged left ventricular end-diastolic diameter and reduced hemoglobin were at higher risk of PH. Nitrate treatment reduced the risk of PH. Elevated creatinine and mean pulmonary arterial pressure (mPAP), diastolic pressure gradient (DPG) ≥7 mmHg, and previous myocardial infarction (MI) entailed a higher risk of mortality in CAD-HF patients with PH. CONCLUSIONS: PH is common in CAD-HF and worsens the hemodynamics and survival in these patients. Left ventricle enlargement and anemia increase the risk of PH in CAD-HF. Patients may benefit from nitrate medications. Renal impairment, elevated mPAP, DPG ≥7 mmHg, and previous MI are strong predictors of mortality in CAD-HF-PH patients.
