Objective To investigate the correlation of serum alpha-fetoprotein (AFP) with clinical pathological factors and prognosis of hepatocellular carcinoma ( HCC ).Methods Two hundred and twenty patients with HCC who hospitalized in our hospital from January 2007 to June 2009 were enrolled in this study.The relationship of AFP levels before operation to clinical pathological factors such as pathological grade,tumor size,tumor encapsulation,tumor numbers,portal vein tumor thrombus,TNM stage and postoperative recurrence were analyzed.Results Serum AFP concentration before operation were related with tumor size ( x2 =11.76,P ＜ 0.05 ),tumor encapsulation ( x2 =17.07,P ＜ 0.05 ),portal vein tumor thrombus ( x2 =8.944,P ＜ 0.05 ),higher TNM stage ( x2 =4.929,P ＜ 0.05 ) and early postoperative recurrence rate ( x2 =5.569,P ＜ 0.05 ).However,it had no correlation with pathological edmondson grade tumor numbers.Conclusion HCC patients with high serum AFP concentration often has greater tumor without encapsulation,high occurrence rate of portal vein tumor thrombus and higher TNM stage,they are more likely to early postoperative recurrence.Serum AFP before operation is useful not only for diagnosis,but also as a prognostic biomarker to predict prognosis and recurrence.

Objective To investigate the effects of preoperative biliary drainage ( PBD ) on the morbidity and mortality of pancreaticoduodenectomy in patients with malignant obstructive jaundice in the lower bile duct. Methods Clinical data of 74 cases undergoing pancreaticoduodenectomy from Jan. 2000 to Dec. 2005 with preoperative total bilirubin level over 85 μmol/L were collected and retrospectively analyzed. Comparison was performed between patients receiving PBD and those not. Before surgery. The parameters sincluding perioperative situation, in-hospital death rate, post-operative complications and were calculated to evaluate the influence of pre-operative biliary drainage on the outcomes. Univariate analysis and Logistic analysis were used to identify the risk factors for post-operative complications. Results Forty (40/74) cases received PTCD procedure. The total bilirubin was significantly reduced from (338. 10±88. 38 )μwnol/L to ( 228. 50±82.24) μ,mol/L in PTCD population and was significantly lower than ( 328. 60±93. 02) μmol/L of the non-PTCD group. There was no significance between the two groups in terms of total complications and individual complication Logistic regression analysis showed that preoperative TB over 340 μmol/L and blood loss over 600 ml were important risk factors for post-operative complications. Conclusion High pre-operative total bilirubin over 340 μmol/L increases the risk of post-operative complications in the patients with malignant jaundice. Preoperative biliary drainage is useful to reduce the total bilirubin and improve the hepatic function of the patients. Prolonged pre-operative biliary drainage could be considered in the patients with high preoperative bilirubin,poor nutritional condition and impaired coagulation to enhance the tolerance of surgery.

To study the antioxidative stress effect of probucol for nonproliferative diabetic retinopathy. METHODS: Sixty - eight clinic patients with nonproliferative diabetic retinopathy were selected from January, 2012 to August, 2013. According to the random number table, the patients were divided into control group and observation group, the control group was received conventional medicine for hypoglycemic therapy, and the observation group was given probucol (0. 375g, twice daily) on the basis of control group. All patients were followed up for average 11. 58 ± 0. 17mo. At the same time 16 healthy volunteers matched with baseline were collected as normal control group. Changes in fasting blood glucose, postprandial blood glucose, glycosylated hemoglobin, the staging progress rate and the remission rate of diabetic retinopathy, and indicators related to oxidative stress, such as, total antioxide capacity ( TAOC ) , superoxide dismutase ( SOD ) , and methane dicarboxy aldehyde ( MDA ) , of two groups of patients before and after therapy were observed.RESULTS: Fasting blood glucose, postprandial blood glucose, and glycosylated hemoglobin of patients in two groups before and after therapy showed no significant changes, and the differences had no statistical significance. The staging remission rate and the progress rate of diabetic retinopathy of the control group after therapy were 3% and 19% respectively. The staging remission rate and the progress rate of diabetic retinopathy of the observation group after probucol therapy were 18% and 5% respectively. ln comparison with the control group, the difference had statistical significance (P<0. 05). TAOC, SOD, MDA of the control group before and after therapy had no obvious change, but TAOC, SOD of the observation group after therapy had significantly increased, and MDA had significantly decreased ( P < 0. 05 ), with statistical significance in comparison with the changes of the patients in the control group after therapy (P<0. 05).CONCLUSlON:Probucol can improve the antioxidative stress status of the patients with nonproliferative diabetic retinopathy, and enhance the therapeutic effect of the patients with diabetic retinopathy.

BACKGROUND:High-density lipoprotein is related to lipid metabolism, but its function cannot be restricted to the scope of lipid metabolism. Simultaneously, exercise regulation has effects on the activity and amount of high-density lipoprotein, but the optimal movement pattern needs to be studied. OBJECTIVE:To offer the theoretical support for formulating fitness training and prospect the possible direction and reference in fol ow-up studying the biological function and exercise regulation of high-density lipoprotein. METHODS:PubMed database was searched for relevant articles published from 1990 to 2015 using the keywords of“HDL and exercise, HDL and biological function”in English. Final y, 44 articles were included in result analysis. RESULTS AND CONCLUSION:The biological functions of high-density lipoprotein mainly include high-density lipoprotein-mediated metabolism of glucose, protein and fat, anti-inflammation, antioxidation and insulin secretion, and at the same time, we summarize the effects of exercise on the concentration, numbers of molecular and components of high-density lipoprotein. The results indicate that the combination of resistance and endurance training is the best way for raising the concentration and functional effects of high-density lipoprotein.

Objective: To evaluate the utility of the Werry-Weiss-Peters Activity Rating Scale (WWPARS) for children with a Chinese background. Methods:In the city of Changsha, 465 normal children aged 8～12 in two primary schools and 27 ADHD children in an outpatient department were tested with WWPARS. Psychometric properties of the scale were analyzed for reliability and validity. Results: While levels of activity increased with age for all children, there was no significant difference between the two groups assessed. The scale attained good reliability and validity. Conclusion: This scale can be applied for evaluation of activity levels for Chinese children.

HMGB-1, an ubiquitously expressed 25-KD nucleoprotein among mammals, belongs to the HMG family. Recent studies have identified that HMGB-1 is secreted by activated monocytes/macrophages via a non-classical ,vesicle-mediated secretory pathway. Extracellular HMGB-1 is an important proinflammatory cytokine. It participates in the pathogenesis of many diseases such as rheumatoid arthritis, sepsis , acute lung injury, and even leads animals death. Further studies of the mechanism and function of extracellular HMGB-1 may provide a novel strategy for the diagnosis and treatment of these diseases.

Objective To understand the clinical characteristics of staphylococcal bloodstream infection in patients with secondary immunodeficiency,as well as the distribution and drug resistance of Staphylococcus aureus (SAU)and coagulase negative Staphylococcus (CNS).Methods A total of 101 patients with Staphylococcus isolated from blood sample were retrospectively reviewed in our hospital.The patients were classified into a group with secondary immunodeficiency and another group with normal immune function as control group.SPSS 18.0 statistical software was used to analyze the data,and compare the two groups of patients in terms of clinical characteristics,pathogens,antibiotic resistance,etc.Results All the 70 patients with staphylococcal bloodstream infection and secondary immunodeficiency had various degrees of fever except 2 cases (temperature < 36 ℃).Chills and shiver were reported in 30.0% of the patients,and migratory lesions in 15.5% of the patients.Lungs were the most common site of infection.About 11.4% of the patients complicated with septic shock.The case strains of SAU,of which 18 (43.9%)strains were MRSA,CNS 29 (41.4%)strains,of which 24 (82.8%)strains were MRCNS.In the control group,26 (83.9%)strains of SAU were identified,of which 11 (42.3%)strains were MRSA,and all the 5 (16.1%)strains of CNS were identified as MRCNS.The incidence of CNS infection in the patients with secondary immunodeficiency was significantly different from that in the control group (P =0.013).All the MRS strains were multidrug-resistant organism (MDRO)except one strain of Staphylococcus intermedius .The staphylococcal strains isolated from the patients with secondary immunodeficiency showed high rate of resistance to penicillin (100%), clindamycin (73.0%), erythromycin (90.0%)and gentamycin (61.0%).No strain was found resistant to tigecycline,linezolid or vancomycin.The resistance rate did not show significant difference between the patients with or without secondary immunodeficiency. Conclusions The clinical characteristics of staphylococcal bloodstream infection in the patients with secondary immunodeficiency are similar to the patients without secondary immunodeficiency,except higher incidence of septic shock and death,but the incidence of CNS infection is relatively higher,MDRO is more prevalent.Antimicrobial agents should be prescribed in clinical practice according to disease conditions and the result of antimicrobial susceptibility testing.
