Value of imaging technology in predicting the clinical end events of liver cirrhosis / 临床肝胆病杂志

The clinical end events of liver cirrhosis have great adverse influence on patients, among which esophageal and gastric varices, portal vein thrombosis, and primary liver cancer might lead to low quality of life and even death. The rapid development of imaging technology provides an important reference for the diagnosis and prediction of the clinical end events of liver cirrhosis. The imaging methods based on ultrasound, contrast-enhanced ultrasound, endoscopic ultrasound, computed tomography (CT), magnetic resonance imaging, multi-slice spiral CT angiography, digital subtraction angiography, and nuclear medicine examination provide great help for clinicians in the diagnosis and evaluation of the clinical end events of liver cirrhosis. However, different imaging techniques may have different features, and therefore, clinicians should use these techniques based on clinical needs.

Value of indocyanine green clearance test in assessing liver reserve function / 临床肝胆病杂志

Basic liver functions can guarantee substance metabolism necessary for the body, and the liver itself has the ability of self-healing and self-regeneration. Routine liver function tests cannot fully reflect the potential of liver parenchyma, i.e., the actual status of liver reserve function. Indocyanine green clearance test is considered an ideal index for liver reserve function. This article reviews the value of indocyanine green clearance test in clinical practice, in order to improve the awareness of the importance of liver reserve function assessment among clinicians.

Role of probiotics in treatment of nonalcoholic fatty liver disease / 中华肝脏病杂志

Nonalcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases in China and manifests as simple fatty liver, non-alcoholic steatohepatitis, liver cirrhosis, and hepatocellular carcinoma. Studies have shown that intestinal flora can affect the development and progression of NAFLD via the "gut-liver axis" . Probiotics are active microorganisms with beneficial effects on the host, and more and more studies have found that probiotics play a positive role in improving NAFLD. They are cheaper, less harmful, and safer compared with antibiotics and surgery, and therefore, it may become a new method for the prevention and treatment of NAFLD. This article reviews the research advances in probiotics in the treatment of NAFLD, in order to provide a basis for the treatment of NAFLD using probiotics.

Risk factors for portal vein thrombosis following splenectomy in patients with liver cirrhosis / 临床肝胆病杂志

Portal vein thrombosis (PVT) develops in some patients with liver cirrhosis and may aggravate portal hypertension. The risk factors for PVT have not yet been completely clarified. Splenectomy might increase the risk of developing PVT, which may progress to a life-threatening complication after splenectomy if not diagnosed promptly and treated properly. In this review, we discuss the recent findings concerning the risk factors for PVT after splenectomy. It is pointed out that splenectomy is the major cause of PVT developed in patients with liver cirrhosis.

Significance of changes in hepatic histology from patients with HBeAg(+)or HBeAg(-)chronic hepatitis B and normal or mildly elevated alanine aminotransferase / 临床肝胆病杂志

Alanine aminotransferase (ALT)abnormality is an indicator of the degree of liver inflammation caused by immune activation in patients with chronic hepatitis B (CHB).However,approximately half of the CHB patients with normal or mildly elevated ALT levels have concealed significant changes in hepatic histology.CHB patients with normal or mildly elevated ALT levels may have significant histopatho-logical changes in hepatic tissues,and those changes vary between HBeAg(+)and HBeAg(-)CHB patients.Attention and investigation on the clinical management of CHB patients with normal or mildly elevated ALT levels may have great significance in grasping the right treat-ment opportunity and reducing the risk of liver cirrhosis.

An ultra high performance liquid chromatography-photodiode array detection-tandem quadrupole mass spectrometry ( UPLC-PAD-MS/MS) method was developed for the determination of total 13 flavonols and flavonol glycosides in red onion which including 6 quercetin and its glycosides, 4 isorhamnetin and its glycosides, 3 Kaempferol and its glycosides. The chromatographic separation was carried out by used a UPLC HSS T3 column and eluted under gradient with mobile phases of acetonitrile and water both contained 0 . 1%formic acid at a flow rate of 0. 3 mL/min. The results showed that the major flavonols and flavonol glycosides in red onion were quercetin-4’-glucoside, quercetin-3, 4’-diglucoside, quercetin and Isorhamnetin-4’-glucoside. The amounts and distributions of flavonols and flavonol glycosides among different parts of red onion were different. For the same amount of dry materials, the content ratio of total flavonols and flavonol glycosides in the outer two layers, the third layer and the inner layer was 60. 3:33. 0:6. 7, the amount of quercitin and its glycosides accounts above 92. 1% of total flavonols and flavonol glycosides for each part. In the outer two layers, the amount of flavonol monoglycosides are the highest, in the third layer, the amount of flavonol aglycones were the highest, but in the inner layer, the amount of flavonol diglycosides were the highest. Small amounts of Kaempferol and its glycosides were found in red onion, and mostly were found in outer layers. This method is simple, fast, accurate and convenient, and can be used to analyze flavonols and flavonol glycosides in onion product.

Hypertension management for migrant workers in the community of Shenzhen city / 中华全科医师杂志

The management model “primary care in community,team service,first contact physician responsibility and two-way referral” was implemented for migrant workers with hypertension in the community.The hypertensive patients under the management for over six months were assigned as management group; the patients who were registered but not under management for over six months served as the control group.The number of new cases detected in hypertension screening increased from 32 in 2008 to 701cases in 2010; and number of hypertensive patients under management increased from 7 cases to 348 accordingly.A questionnaire survey was conducted in 464 hypertensive patients,including 196 cases in management group and 268 cases in control group with a response rate of 94.9％ (186/196) and 92.5％ (248/268) respectively.The results showed that drug compliance rate in management group (168/186,90.3％ ) was significantly higher than that in the control group ( 26.6％,66/248,P =0.00 ).The rate of blood pressure control in management group (87.1％,162/186 ) was significantly higher than that in the control group (25.8％,64/248,P =0.00).The overall satisfaction (98.9％) in management group was significantly higher than that in the control group (88.7％,P =0.00 ).The results indicate that implementation of the hypertension management in migrant workers improves the health seeking behavior and blood pressure control of patients.

Chinese medicine for treatment of chronic hepatitis B / 中国结合医学杂志

Contemporary Western medicines approved by the U.S. Food and Drug Administration (FDA) for the treatment of chronic hepatitis B (CHB), although available in China, have high costs, or major side effects and limited effectiveness. Research efforts have focused on looking for natural products as alternative medicines with low cost and good safety for CHB treatment. Chinese medicine (CM) has ancient, time-honored theories about methods of diagnosis and treatment for liver diseases. In recent decades, a large number of clinical trials and pre-clinical studies, which were performed in China and other countries, indicated that CM has potential benefit in several aspects of the treatment of CHB, e.g., anti-inflammatory, anticancer, antioxidant, immunomodulating, antifibrosis, and antiviral. However, there are many concerns regarding the study design and the quality of clinical trials. Further larger, stringently designed, double-blind, placebo control, randomized clinical trials and long-term follow-up are needed to provide conclusive evidence of their efficacy and safety. Components of CM deserve further study in pre-clinical models of HBV infection and in clinical trials world-wide.

A Comparative Study of Three Echocardiographic Methods in Determining Left Ventricular Function / 第三军医大学学报

The left ventricular function of 103 normal subjects in the age range of 17 to 48 were examined with three echocardiographic methods, the Pombo's method (Method I), Fortuin's method (Method II) and Lalani's method (Method III), in order to evaluate their relative efficiency. The results were as following:( 1 ) The value of left ventricular end diastolic volume determined with Method II was larger than that determined with Method 1(123. 9?22.6vsl05. 43?26.0 ml, P0. 05).( 2 ) The values of stroke volume, stroke index, cardiac output, and cardiac index were the largest as determined with Method II, the second with Method I and the smallest with Method III. For instance, the value of cardiac index was 4.66 ?1.21 /m2/min wita Method 11,3.81?1.0 with Method I, and 2.96?0.8 with Method III(P0. 05).( 4 ) All the parameters obtained from Methods I and II were correlated with each other closely (r = 0.72 - 0.96, P0.05).( 5 ) Methods I and II are simple to operate and easy to reproduce and there have been a lot of parameters obtained with these two methodds. However the systolic mitral closure slope of Method III is rather difficult to determine and the parameters obtained with Method III are comparatively less in number.It is concluded that Methods I and I of the echocardiographic technique are the methods of choice in determining the left ventricular function of a normals-sized or nearly normal-sized heart since they are simple, effective and accurate.

Ultrasonographic Observation on Dilatation cardiomyopathy / 第三军医大学学报

Twenty cases of clinically diagnosed dilatation cardiomyopathy (DCM) were examined with the Model XJY-6 ultrasound instrument to determine the anatomical changes of their hearts and the changes of their left ventricular diastolic function (LVDF) . Twenty healthy individuals were also examined as control. The following results were observed.Most patients exhibited dilatation of all the chambers and the increase of the left ventricular weight, however, dilatation was the main manifestation. Cardiac dilatation and hypertrophy present the similar pictures on radiograph or ECG, differentiation of the two conditions can hardly be made with either of the above methods, but must depend on ultrasound especially in cases complicated with left atrial dilatation and fibrillation.The changes of LVDF of DCM patients revealed by ultrasoundfwere the abnormalities of the amplitude and rate of the posterior wall movement and of the dias-tolic filling volume and filling rate of the left ventricle. It was found that the PWE, DPWV, RFF, RER/ESV of the patients were much lower than those of the control (P
