Objective To compare the differences between MELD and Child-Pugh grading in assessing of hepatic functional reserve in patients with cirrhosis,and analyse the correlation of two systems.Methods Retrospective analysis was made on 92 cases of hepatitis cirrhosis hospitalized with the MELD and Child-Pugh score by ROC curve,the difference and relation between two systems were compared.Results MELD and Child-Pugh system were significantly correlated(r=0.669,P < 0.000),3-month survival in patients with two systems ROC curve areas was significantly different(P < 0.05),while the MELD in patients survived more than 6 months was not significantly different compared with Child-Pugh(P>0.05).ConclusionMELD and Child-Pugh can accurately assess the prognosis of survival for patients with hepatic cirrhosis,and MELD is suitable for assessment of risk,heavy patients,not for those survived more than 6 months.

AIM To investigate if inhibiting neutrophil infiltration and adhesion molecules expression is a part of the mechanisms of ginsenoside Rg1 protecting from cerebral injury after cerebral ischemia-reperfusion. METHODS Rats were pretreated with ginsenoside Rg1 25, 50 and 100 mg·kg-1·d-1, ig, for 7 d, respectively, then subjected to cerebral ischemia (middle cerebral artery occlusion) for 2 h and reperfusion for 22 h. The infarct volume and the neurological deficit were determined by TTC staining and Longa's scoring, respectively. The infiltration of neutrophils was evaluated by measuring the activity of myeloperoxidase (MPO). The expressions of intercellular adhesion molecule-1 (ICAM-1) and E-selectin were analyzed by Western blot. The permeability of the blood-brain barrier was evaluated by measurement of Evans blue content in brain tissue with spectrophotometer at 4 h after reperfusion. RESULTSCompared with vehicle-treated group, ginsenoside Rg1 (50 and 100 mg·kg-1·d-1) treatment significantly reduced infarct volume and elevated permeability of blood-brain barrier, alleviated the neurological deficit, and inhibited protein expressions of ICAM-1 and E-selectin in brain tissue. CONCLUSION Ginsenoside Rg1 has protective effects on cerebral injury induced by ischemia-reperfusion through inhibiting neutrophil infiltration and expression of the adhesion molecules.

Objective To investigate the association between genetic polymorphisms and protein levels of mannose-binding lectin (MBL) and the sensitivities of common infections in a pediatric Han population lived in Zhejiang Province.Methods MBL genetic polymorphisms of patients and controls were detected by PCR-based sequencing.MBL protein levels were measured using MBL ELISA Kit.Results No mutations at positions +223 and +239 of the exon 1 were detected in either patients or controls.No mutation at position +4 of the promoter was detected in controls.The frequencies of the three genotypes HH,HL,and LL at position-550 of the promoter were different between patients and controls(P＜0.05).The frequencies of genotypes YA and XB relevant to MBL protein levels were also different between patients and controls(P＜0.05).Comparing the frequencies of genotypes YA and XB in separate infectious disease with controls,significant differences were found in the group of RRI and CMV infection.The distributions of serum MBL level frequencies in patients and controls were both characterized by skewed distributions.MBL levels of patients with CMV infection were lower than those of controls(P＜0.05).Inversely,MBL levels of patients with acute respiratory infection and localized abscess were higher than those of controls (P＜O.05).Conclusion Genetic polymorphism of MBL gene is seemed to be relative to the sensitivity of common infections in children.

Objective To establish a screening system of efficient small interfering RNA (siRNA) target sites directed against truncated region of human cytomegalovirus (HCMV) UL54 gene (UL54S) with siRNA expression vectors. Methods Two small hairpin RNA (shRNA) expression vectors targeting truncated region of HCMV UL54 gene were constructed based on pAVU6 + 27 vector, and cotransfected into AD293 cells with the fusion protein expression vectors pUL54S-enhanced green fluorescent protein (EGFP). The levels of mRNA and EGFP were evaluated by means of reverse transcription-polymerase chain reaction (RT-PCR), fluorescence microscopy and flow cytometry so as to assess the inhibitory efficiency of siRNA. Analysis of variance was applied to analyze the variance of total fluorescence intensity to screen out the efficient target sites of siRNA.Results shRNA expression vector psiUL54-2 and fusion protein expression vector pUL54S-EGFP were cotransfected into AD293 cells. The EGFP expression level in pUL54S-EGFP/psiUL54-2 cotransfected group was lower than that in pUL54S-EGFP/pAVU6 +27 cotransfected group after 48 h of transfection. Gel analysis showed that the mRNA relative level of UL54S was 19.6 after 48 h of psiUL54-2/pUL54S-EGFP cotransfection, which was significantly lower than those in pUL54S-EGFP/psiUL54-1 group (96.6) and control group (100.0). Cotransfection of psiUL54-1/pUL54S-EGFP for 48h didn't show any effects on the expression of fusion protein UL54S-EGFP (P>0. 05).While psiUL54-1/pUL54S-EGFP cotransfection inhibited the expression of fusion protein UL54S-EGFP(19.43×104±2.29×104vs27.89×104±5.50×104, P<0.01).Conclusion Thescreening system of efficient siRNA targeting truncated region of HCMV UL54S is established successfully. The 1532th-1550th nucleotide acids of UL54S coding sequence are efficient siRNA target sites.

Objective To investigate the effect and the mechanism of intragastric administration of gentamicin and lactulose on stress ulcer in rats with obstructive jaundice.Methods Forty male Wistar rats were divided into 4 groups: Jaundice(Ligation of the bile duct) and intragastric administration of gentamicin and lactulose(group A),jaundice with intragastric glucose(group B),sham operation with intragastris gentamicin and lactulose(group C);and sham operation with intragastric glucose(group D).Two weeks after the operation,the respective intragastric administration was given for 7 days,and then the water immersion and restraint stress induction procedures were performed in the 4 groups.Endotoxemia levels in portal vein were measured by the Limulus test and the ulcer index was calculated.Results Group A showed significantly lower ulcer index and lower level of endotoxemia compared to group B,while the levels of endotoxemia and ulcer index in group B were increased,and group C and D also showed lower ulcer index and lower level of endotoxemia.Conclusions Endotoxemia is an important aggravating factor for stress ulcer in obstructive jaundice.Intragastric administration of lactulose and gentamicin can decrease the level of endotoxemia which is beneficial to reduce the incidence of stress ulcer in rats with obstructive jaundice.

Objective:To determine expression levels of ubiquitin C-terminal hydrolase-L1 (UCH-L1) and serum glial fibrillary acidic protein (GFAP) in patients with acute cerebral infarction and their clinical significance.Methods:A total of 80 patients with acute cerebral infarction in Chongqing Cancer Hospital from January 2014 to February 2016 were enrolled as an observation group.Another 80 healthy people served as a control group.The expression levels of UCH-L1 and GFAP in the 2 groups were detected.Results:Sensibility and specificity for UCH-L1 and GFAP were 75.0％,87.5％ and 81.3％,90.0％,respectively.Receiver operating characteristic curve areas of UCH-L1 and GFAP were 0.670 and 0.757,respectively.There were no significant significance in age,gender,drinking,smoke,diabetes,and hyperlipidemia in the 2 groups (P＞0.05).High blood pressure rate in the observation group was higher than that in the control group (P＜0.05).Spearson/Pearson analysis showed that serum UCH-L1 and GFAP levels were positively correlated with hypertension,but they were negatively correlated with sex,age,diabetes,hyperlipidemia,alcohol consumption,smoking,and other factors.General data at different time in the observation group was not statistically different (P＞0.05).The expression levels of UCH-L1 and GFAP in the observation group was higher than that in the control group (P＜0.05).UCH-L1 and GFAP levels at different time in the 2 groups were not statistically different (P＞0.05).UCH-L1 and GFAP levels in the light,medium,and heavy groups were higher than those in the control group (P＜0.05),while UCH-L1 and GFAP levels in the medium and heavy groups were higher than those in the light group (P＜0.05).There was significant difference between levels of UCH-L1 or GFAP and infarction size at different time in the observation group (P＜0.05).The results of Pearson correlation analysis showed that the levels of serum UCH-L1 and GFAP were positively correlated (r=0.634,P=0.001).Conclusion:The levels of serum UCH-L1 and GFAP are significantly increased at the early stage of acute cerebral infarction,and they have a certain correlation with the severity of cerebral infarction,which can provide a basis for early clinical diagnosis and treatment.

Objective To observe the effects of atorvastatin calcium on serum tumor necrosis factor alpha (TNF)-α and C-reactive protein (CRP) in patients with acute cerebral infarction (ACI), so as to approach the mechanism of atorvastatin calcium inhibiting ACI inflammatory injury. Methods Eighty-four patients with ACI were randomly divided into 2 groups: group B (42 cases, treated with antiplatelet therapy and improving cerebral circulation), group A(42 cases, treated with atorvastatin calcium 20 mg/d after the onset of ACI for 28 days on the base of group B). TNF- α and CRP were detected before treatment and in the 3rd,7th day after treatment. The European stroke scale (ESS) was evaluated on the same time. A healthy control group (group C, 16 cases) was also included in the study. Results The peak of CRP and TNF-α levels were observed in the 3rd and 7th day after treatment respectively, and the levels of group A were lower than those of group B [(13.00 ± 2.45) mg/L vs (19.21 ± 3.67) mg/L,(19.79 ± 11.01) ng/L vs (30.69 ± 18.47) ng/L, P < 0.05]. In the 7th day after treatment, the scores of ESS was higher in group A than that in group B [(79.19 ± 30.59) scores vs (63.91 ± 27.87) scores, P < 0.05]. Conclusions Atorvastatin calcium can prevent the increase of serum TNF-α and CRP, and it has anti-inflammatory effect. Atorvastatin calcium may have the role of neuroprotection besides lipid-lowering.

Objective To explore the role of CD4+ CDhigh25 regulatory T cells in the pathogenesis of chronic abacterial prostatitis/chronic pelvic pain syndrome (CAP/CPPS).Methods The percentage of CD4+ CD+25 and CD4+ CDhigh25 regulatory T cells was detected by flow cytometry from 45 CAP/CPPS pa-tients and 18 normal controls.The levels of interleukin-6(IL-6),IL-10,tumor necrosis factor-α(TNF-α) and transforming growth factor-β1 (TGF-β1) in serum and seminal plasma were measured by ELISA in the same cohort.Results There was no significant difference in the percentage of peripheral blood CD4+CD+25 and CD4+Cdhigh+ cells between CAP/CPPS patients and normal control (P>0.05).The ser-CD4+CD+25 and CD4+Cdhigh+ cells between CAP/CPPS patients and normal control (P>0.05>.The ser-um levels of TGF-β1 in patients with CAP/CPPS were markedly lower than those in controls (P<0.05),serum TNF-α and seminal plasma IL-6,TGF-β1 and TNF-α in CAP/CPPS patients were markedly higher than those in controls (P<0.05).There was a positive correlation between the IL-6 and the NIH-CPSI.There was also a positive correlation between the IL-10 and the pain index.In ad-dition,the percentage of peripheral blood CD+4CDhigh25 cells was positively correlated with serum TGF-β1.But the percentage of CD+4CDhigh25 cells had no correlation with ages,duration of CAP/CPPS pa-tients,NIH-CPSI and the other cytokines.Conclusions The defective function of peripheral blood CD+4CD+25 regulatory T cells may be related with the pathogenesis of CAP/CPPS.The cytokines may also play an important role in the process of pathogenesis of CAP/CPPS.
