Objective To explore the early diagnostic value of Golgi membrane protein 73 (GP73),alpha-fetoprotein (AFP) and alpha-fetoprotein-L3 (AFP-L3) in patients with high risk of primary hepatic carcinoma (PHC).Methods Sixty-four cases of PHC were selected as the PHC group,60 cases of liver cirrhosis(LC) as the LC group,53 cases of hepatitis as the hepatitis group and 51 healthy checked-up people as the control group.Enzyme-linked immunosorbent assay (ELISA) was used to detect the serum level of GP73 in all the cases.AFP-L3 was isolated by using affinity micro centrifugal column,AFP and AFP-L3 were detected with chemiluminescent immunoassay and then the proportion of AFP-L3 was calculated.Results The positive rate of serum GP73,AFP and AFP-L3 in PHC group was significantly higher than that in LC group and hepatitis group [78.1％ (50/64)vs.25.0％ (15/60),17.0％ (9/53);48.4％ (31/64) vs.31.7％ (19/60),22.6％(12/53) ;53.1％(34/64) vs.30.0％(18/60),20.8％(11/53)] (P ＜ 0.05),In control group,GP73,AFP,AFP-L3 was no positive.The levels of GP73,AFP and AFP-L3 in PHC group were significantly higher than those in LC group,hepatitis group and control group [(245.69 ± 89.18)μ g/L vs.(116.37 ±38.52),(97.29 ± 24.58),(23.48 ±9.12) μ g/L; (403.27 ± 128.46) μg/L vs.(75.62 ± 19.35),(66.49 ± 15.14),(3.46 ± 1.02) μg/L; (15.64 ±3.19)％ vs.(5.24 ± 1.15),(4.21 ± 0.96),(2.95 ±0.73)％] (P ＜0.05).The levels of GP73,AFP in LC group and hepatitis group were significantly higher than those in control group (P ＜ 0.05).The levels of GP73,AFP and AFP-L3 had no statistically significant difference between LC group and hepatitis group (P ＞ 0.05).Sensitivity and accuracy of three combined detection for PHC was 96.9％(62/64),91.7％(209/228),significantly higher than that of AFP,AFP-L3 single detection (P ＜ 0.05).GP73 single detection and any two combined detection was no significant difference in sensitivity and accuracy,compared with three combined detection (P ＞ 0.05).The levels of GP73 in PHC patients with different age,gender,serum level of AFP,TNM stage and tumor diameter had no statistically significant difference (P ＞ 0.05).The levels of GP73 in PHC patients with positive HBsAg,extrahepatic metastases and LC had significant difference (P ＜ 0.05).Conclusions The diagnosis value of GP73 is evidently higher than AFP and AFP-L3 for PHC,and combined determination is superior to single marker.Combined determination enhances the degree of precision in populations with high risk of PHC diagnosis.

BACKGROUND:Phytohemagglutinin (PHA) can stimulate the peripheral blood mononuclear cells (PBMCs) into cellcycle, and cause their immune activation, which is a common immune proliferation model. However, the role of non-PBMC ingredient of peripheral blood is unclear, as wel as the expression of endothelial cells related cytokines. OBJECTIVE:To study the effect of whole blood culture and PBMCs alone culture with PHA on the PBMC proliferation and apoptosis, expression of inflammatory cytokine and endothelial cellsecreted cytokine markers. METHODS:Morphological changes of PBMCs separated from normal karyotype human peripheral blood individual y cultured with or without PHA were observed. The PBMCs were col ected by whole blood culture or PBMC separated culture. mRNA was extracted for the fluorescence quantitative RT-PCR, which was applied to detect the cellproliferation, apoptosis, and expression of inflammatory cytokine and endothelial cellsecreted cytokines. The statistic analysis was used for the significance explication. RESULTS AND CONCLUSION:PBMCs alone cultured ere different from those undergoing whole blood culture. The PHA could up-regulate the gene expression of Ki67, proliferating cellnuclear antigen, Caspase 3, interferon-γ, tumor necrosis factor-βand interleukin-6, but down-regulate Protein C. This indicted that PHA could promote the proliferation and apoptosis of PBMCs and up-regulate the expression of inflammatory cytokines, but down-regulate the expression of endothelial cells secreted coagulation cytokines.

This article was aimed to rapidly analyze chemical composition in A loe Barbadensis Mill, and to compare the chemical composition of commercial aloe vera medicinal materials with that of fresh aloe yellow exudate. An opti-mized liquid chromatography-mass spectrometry-ion trap-time-of-flight (LCMS-IT-TOF) method was applied for the analysis of commercial aloe vera medicinal materials and fresh aloe yellow exudates. The Agilent TC-C18 column (4.6 í 250 mm, 5 m) was used. The gradient elution was a solvent system of water(A)-methanol(B). ESI source was operated in both positive and negative ion modes. The results showed that chromones, pyrones, naphthalene deriva-tive, anthrones and anthraquinones were separated successfully, 30 compounds were characterized by the comparison of characteristic MS/MS fragment ions data with the literature. The diagnostic fragmentation patterns of different chemical compositions were also discussed on the basis of EST-IT-TOF MS data. It was concluded that the chemical composition of commercial aloe vera medicinal materials were significantly different from that of fresh aloe yellow ex-udate in terms of types and contents: the former one mainly contains isoaloeresin D and aloin, and few aloesin; but the latter is mainly composed of aloesin and aloin, and the content of aloesin is the highest. The LCMS-IT-TOF analysis can be used to rapidly obtain rich structural information of different chemical compositions, which improves the efficiency of qualitative analysis of chemical composition, and is of great significance to the quality control, eval-uation and the utilization of A loe Barbadensis Mill.

[Abstract] Objective To study the effects of resveratrol on chemokines CCR5,CXCL10 of serum and synovial fluid in acute gouty arthritis of rats.Methods According to random number table,36 Wista rats were divided into six groups:i.e.control group,model group,colchicine group,high dose resveratrol group (HR),medium dose resveratrol group (MR),and low dose resveratrol group (LR).The rats were respectively administrated with normal saline,colchicine suspension,high dose resveratrol,medium dose resveratrol,low dose resveratrol for 7 days,once a day.Rats acute gouty arthritis modles were estalished on the fourth day by monosodium urate solution (concentration of 25 mg/ml,0.05 ml) injected into the ankle cavity,while 0.05 ml normal saline was injected into joint cavity of rats in control group.2,9,24,48,72 hours after model estabilishment,blood samples were collected from inner canthus to detect levels of interleukin (IL)-1β,CCR5,CXCL10.72 hours after model estabilishment,synovial fluid were collected from ankel to detect levels of IL-1β,CCR5,CXCL10.The joint swelling index was observed periodically.Results The levels of IL-1 β in the low,medium,and high doses of resveratrol were (9.63 ± 0.71),(7.67 ± 0.48),and (6.66 ± 0.29) pg/ml respectively,being significantly lower than that in the model group (11.85 ± 0.45) pg/ml (P＜0.05) in joint fluid.The levels of CCR5 in the medium and high doses of resveratrol groups were(4.49 ± 0.25) and (4.65 ± 0.25) ng/ml respectively,being significantly lower than that in the model group (5.64 ± 0.28) ng/ml (P＜0.05).The levels of CXCL10 in the medium and high doses of resveratrol groups were significantly lower than that in the model group [(86.79 ± 2.90) and (89.61 ± 5.47) vs (110.13 ± 4.02) pg/ml,P＜ 0.05].The histopathologic results showed that resveratrol might reduce acute gouty arthritis joint edema,improve inflammatory cells infiltrating.Conclusions The levels of IL-1β,CCR5,and CXCL10 were raised in acute gouty arthritis.Resveratrol effectively controls acute gouty arthritis attack,and the curative effect is dose dependent.

Objective To retrospectively analyze the clinical epidemiology features of adult idiopathic membranous nephropathy (IMN) in Zhongshan Hospital,and to investigate their therapeutic effect and its possible influence factors.Methods A total of 183 patients admitted to the Zhongshan Hospital of Fudan University and diagnosed as IMN by renal biopsy from January 2013 to December 2015 were involved.Their baseline information including demographics and pathologic was collected.Patients were followed up for at least 12 months.Serum albumin ＜ 30 g/L and 24 h urine protein ＞ 3.5g were defined as nephrotic syndrome (NS).IMN patients were divided into NS and non-NS groups and compared.Furthermore,the baseline data of remission and no remission patients were compared,and the correlations of their baseline data with conservative and immunosuppressive therapy were assessed by logistic regression analysis.Results (1) IMN accounted for 11.1％ of renal biopsy cases in our hospital,with an average age of 57 years and 59.6％ male patients.(2) Compared with patients without NS,IMN patients with NS were older,had a shorter time from the onset to receive renal biopsy,lower estimated glomerular filtration rate,and higher total cholesterol,low density lipoprotein cholesterol,triglyceride and serum creatinine (all P ＜ 0.05).(3) The effective rate of conservative treatment in IMN patients without NS was 65.7％,and the ineffective group had higher triglyceride compared with the effective group (P=0.019).(4) The effective rate of immunosuppressive therapy in IMN patients with NS was 81.2％,and low serum albumin was an independent risk factor for the poor efficacy of immunosuppressive therapy (OR=1.202,95％ CI 1.003-1.440,P=0.046).(5) The effective rate of conservative treatment in IMN patients with NS was 55.5％,and low serum albumin was an independent risk factor for the poor efficacy of conservative treatment (OR=1.629,95％CI 1.047-2.536,P=0.023).Conclusions The detection rate of IMN is increasing year by year,but the remission rate of conservative treatment is still not low in mild and moderate patients.For the patients without NS,high triglyceride may predict a poor effect of conservative treatment.Hypoproteinemia is a predictor of poor effect,no matter what a NS patient takes immunosuppressive therapy or conservative treatment.

Objective To study the effects of resveratrol on acute gouty arthritis.Methods According to random number table,thirty-six Wista rats were randomly divided into six groups:the control group,the model group,the colchicine treatment group,the high dose resveratrol group,the medium dose resveratrol group,the low dose resveratrol group.They were administrated with normal saline,colchicine suspension,high dose resveratrol,medium dose resveratrol,low dose resveratrol for 7 days once daily.Acute gouty arthritis rats models were established on the fourth day by injecting monosodium urate solution (concentration of 25 mg/ml,0.05 ml) into the ankle joint,while 0.05 ml normal saline was injected into the joint of the control rats.Seventy-two hours after the model was established,the synovial fluid were collected from ankle joints for the measuring of the level of IL-1β,CXCL10.NF-κB p65 protein levels were assayed with Western blotting.The joint synovia were fixed for histopathological examination with 10％ fromaldehyde.Variance analysis were used.Results The values of IL-1β in the low,medium and high doses of resveratrol were (9.63±0.71),(7.67±0.48) and (6.66±0.29) pg/ml respectively,being significantly lower than that in the model group (11.85±0.45) pg/ml (P＜0.05).The values of CXCL10 in the medium and high doses of resveratrol were (86.8±2.9) and (89.6±5.5) pg/ml respectively,being significantly lower than that in the model group (110.1±4.0) pg/ml (P＜0.05).The Western blotting results showed that the expression of NF-κB p65 protein in the high dose resveratrol group decreased evidently than that in the model group.The histopathological examination showed that resveratrol might reduce joint edema,decrease inflammatory cells infiltration in acute gouty arthritis.Conclusion The levels of IL-1β,CXCL10 and the expression of NF-κB p65 protein are elevated in acute gouty arthritis.The resveratrol can effectively control acute gouty arthritis attacks,and its efficacy is dose dependent.

Objective To investigate the effects of changes of miR-126 and spouty related EVH,domain containing proteinl(SPRED1) after transient ischemic attack(TIA)on prognostic value for pathogenesis of secondary cerebral infarction.Methods Retrospective analysis of the clinical data of 106 patients with TIA was performed.The expression levels of miR-126,SPRED1 and vascular endothelial growth factor(VEGF)in peripheral blood were detected at 3 h,6 h and 12 h after TIA onset respectively.The specificity and sensitivity of miR 126 and SPRED1 in the diagnosis of TIA were analyzed.The miR-126 and SPRED1 levels versus ABCD2 score were compared for evaluating their predictive value in the diagnosis of secondary cerebral infarction within 30 days after TIA onset.Results The miR-126 level was declined after TIA onset at 3 h(9.41±1.04),especially at 12 h(6.59 ±2.78),versus in healthy control (9.35±1.76)(t =-7.764,P=0.000).The SPRED1 level after TIA onset was increased at 3 h(58.05 ± 17.53)pg/L,12 h(82.64 ± 18.60)pg/L versus in healthy control(52.38 ± 13.24)pg/L(t=12.374,P =0.000).A closely negative correlation was found between levels of miR 126 and SPRED1 at 12 h point but not at 3 h and 6 h(r=-0.278,P=0.004).Both miR-126 and SPRED1 levels at 12 h after TIA were implied to sensitivity and specificity evaluation.Additionally,VEGF was significantly increased at 3 h (345.61 ± 76.76) pg/L,6 h (461.65 ±103.87)pg/L and 12 h (519.22 ± 103.55)pg/L after TIA onset as compared with healthy control (107.77± 26.04) pg/L(t =26.569,29.756,34.699,all P =0.000).The decrease of miR-126 and increase of SPRED1 at 12h after TIA indicated high incidences of cerebral infarction but their significance was less than ABCD2 score.Combination of miR 126,SPRED1 and ABCD2 score significantly improved the prediction for cerebral infarction(Z=2.105,P =0.035).Conclusions After the onset of TIA,levels of miR-126 and SPRED1 expression in combination of ABCD2 score can improve predictive value for cerebral infarction development.
