OBJECTIVETo investigate the short-term prognostic value of the indocyanine green clearance test when used in combination with the model for end-stage liver disease (MELD) scoring system to assess patients with hepatitis B virus acute-on-chronic liver failure (HBV-ACLF).

METHODSClinical data of 105 patients diagnosed with HBV-ACLF were retrospectively analyzed. The indocyanine green retention rate at 15 minutes (ICGR15), clinical data within 24 h after diagnosis, Child-Turcotte-Pugh (CTP) classification, MELD score, MELD combined with sodium concentration (MELD-Na) score, and King's Hospital (KCH) criteria data were collected for analysis. Measurement data were assessed by t-test and count data by the chi-square test. Short-term predictive accuracy for patients with HBV-ACLF was compared between different models using the area under the receiver operating characteristic (ROC) curve (AUC).

RESULTSThe mortality rate for all patients was 45.71%. Comparison of the survivors versus the non-survivors showed that age, total bilirubin, albumin, cholinesterase, creatinine, international normalized ratio, and incidence positive rate of relative complications (hepatorenal syndrome, hepatic encephalopathy) were significantly different between the two groups (all, P less than 0.05). The ICGR15 was found to be positively correlated with MELD score (r = 0.205, P less than 0.05). The MELD-ICGR15 model constructed by logistic regression analysis was: Logit(P) = 0.193 * MELD + 0.130 * ICGR15 - 11.256. The AUC was 0.880 and the cut-off was -0.706, with 89.6% sensitivity and 75.4% specificity. The AUC of the MELD-ICGR15 model was significantly higher than that of the ICGR15 (0.820), MELD score (0.779), MELD-Na score (0.761), KCH criteria (0.680), and CTP classification (0.631) (all, P less than 0.05).

CONCLUSIONICGR15, MELD score, and MELD-Na score had higher predictive values for HBV-ACLF than did CTP classification or KCH criteria. Furthermore, the MELD-ICGR15 model was better than any single parameter model for predicting the short-term prognosis of patients with HBV-ACLF.

Objective To observe the effect of the electroacupuncture ( EA) on the expression of cyclin-de-pendent kinase 5 ( Cdk5 ) in rats with muscle contusion and to explore its mechanism. Methods Thirty-two Sprague-Dawley rats were randomly divided into a normal group of 4, a model group of 4, a natural recovery group ( NR) of 12 and an EA group of 12. All except those in the normal group had acute skeletal muscle contusion induced through a heavy blow. The EA group was treated with 15 minutes of EA daily beginning 48 h after the injury while the other rats received no EA. The model group was sacrificed 24 h after modeling, and rats from the NR and EA groups were sacrificed on the 7th, 14th and 21st day after the modeling to collect tissues. Hematoxylin eosin ( HE) staining, Western blotting and quantitative real-time fluorescence PCR were used to observe any histological changes, as well as Cdk5 protein and mRNA expression. Results The HE staining showed that the other 3 groups displayed larger a-mounts of muscle fiber fracture, dissolution and inflammatory cell invasion than was observed in the normal group. Compared with the NR group, quicker recovery was seen in the EA group as evidenced by faster muscle satellite cell proliferation and more new muscle fiber generation. The average Cdk5 protein expression in both the NR and EA groups was higher than in the normal group, and that of the EA group was significantly lower than that of the NR group. Conclusions Muscle contusion can increase Cdk5 expression in skeletal muscles, at least in rats. EA can promote the restoration of skeletal muscle function, probably by inhibiting CDK5 protein and mRNA expression.

Object To develop an immunoassay method of species-specific protein for Radix Glycyrrhizae (RG) identification. Methods The crude drug of RG as a model was studied in this paper,the antigen of RG protein (RGP) was screened by Western-blot analysis using anti-RG serum. After species-specific protein,RGP was purified,and rabbit antiserum against RGP was prepared,the rabbit IgG of anti-RGP was isolated and biotinylated,then the sandwich enzyme-linked immuosorbent assay (ELISA) was developed. Results The method was only specific to RG,which was harvested from various areas or species,and showed excellent sensitivity and reproducibility. Conclusion The result suggests that the immunoassay method using specific antigen of RGP as a detection objective be a new potential for the unequivocal identification and quality control of RG.

Objective:To explore the role of lectin-like oxidized low density lipoprotein (ox-LDL) receptor(LOX1) in ox-LDL stimulating endothelial nitric oxide(NO) production. Methods: LOX1 mRNA expression was detected by reverse transcription-polymerase chain reaction(RT-PCR). The quantity of NO was detected by Enzyme-method. Results: Incubation of ox-LDL increased endothelial NO production and LOX1 mRNA expression. When HUVECs were incubated with ox-LDL as well as the inhibitor of LOX1, polyinosinic acid,the increase of NO production and LOX1mRNA expression were attenuated. Conclusion: Ox-LDL enhanced endothelial NO production in a concentration-dependent manner, and the effect of ox-LDL on endothelial NO was mediated by LOX1.

Objective To investigate the clinical and pathologic features of patients with gastric neuroendocrine neoplasms (g-NENs).Methods A total of 50 cases of g-NENs diagnosed by pathology in the First Hospital of Jilin University from May 2012 to January 2016 were retrospective analyzed to summarize the clinical manifestations and pathological features.The location of lesion,gross morphology,maximum diameter,lymph node metastasis rate,distant metastasis rate,and survival time between patients with neuroendocrine tumors and neuroendocrine carcinomas were compared.Results Among the 50 patients,34 were males and 16 were females with a male to female ratio of 2.125 ∶ 1.Their age ranged from 33 to 77 years with an mean age of 60± 11 years.There were 13 cases (26％) of neuroendocrine tumors,31 (62％) neuroendocrine carcinomas,and 6 (12％) mixed adenoneuroendocrine carcinomas.The maximum diameter of lesion was less than 2 cm in 8 cases (16％),and equal or greater than 2 cm in 42 cases (84％).There was single lesion in 48 cases (96％) and multiple lesions in 2 cases (4％).There were 19 cases (38％) located in gastric antrum,16 (32％) in gastric body,11 (22％) in gastric fundus or cardia,3 (6％) in gastric angle,and 1 (2％) in the junction of gastric antrum and body.Thirty-two patients (64％) had metastasis,including 20 cases of lymph node metastasis and 12 cases of distant metastasis.The clinical symptoms of the patients were different,mainly were digestive system symptoms and tumor occupying symptoms,and no carcinoid syndrome was reported.The gross morphology (x2 =24.446.P =0.000).maximum diameter (t =-4.044,P =0.001),lymph node metastasis rate (x2=4.435,P =0.035),and survival time (t =2.925,P =0.000) were significantly differences between 13 cases of neuroendocrine tumors and 37 cases of neuroendocrine carcinoma.But the location of lesion (x2 =6.921,P=0.082) and distant metastasis rate (x2 =0.715,P =0.389) were no statistically different between the two groups.Conclusion Gastric neuroendocrine neoplasms can occur in any part of stomach,majority of tumor is single lesion and lack of specific clinical manifestations.The mostly gross morphology of gastric neuroendocrine carcinoma and mixed adenoneuro-endocrine carcinoma are ulcer type with a large diameter and poor prognosis.

OBJECTIVETo develop a RP-HPLC method for the determination of the concentration of hydroxysafflor yellow A in rat plasma, to study the pharmacokinetics of Carthamus tinctorius extration and Naodesheng tablet, and to investigate the effect of other components on the pharmacokinetics of hydroxysafflor yellow A.

METHODThe rats were orally treated with Carthamus tinctorius extration and Naodesheng capsule respectively. Blood samples were collected in heparinized eppendorf tube via the oculi chorioideae vein. Plasma was separated by centrifugation at 10 000 r x min(-1) for 10 min, and two-times methanol in volume was added to deposit proteins. After centrifugation, the upper liquid was transferred to filter. The concentration of hydroxysafflor yellow A in serum was determined by RP-HPLC. The stationary phase was C18, and methanol-acetonitrile-0.7% orthophosphoric acid (26: 2:72) was taken as the mobile phase, A UV detector was used at 403 nm. The pharmacokinetic parameters were calculated with 3p97 program.

RESULTA good linear relationship of hydroxysafflor yellow A was obtained in the range of 0.03 and 2.56 mg x L(-1), the lowest limit of determination was 10 microg x L(-1), and the lowest limit of quantitation was 30 microg x L(-1). The mean recoveries were (99.3 +/- 1.4)%, (92.8 +/- 1.8)%, (98.4 +/- 2.0)% for high, middle, low concentrations of the samples respectively. The plasma concentration-time curves of hydroxysafflor yellow A were fitted with two-compartments model. The AUC)0-t), AUC(0-infinity), C(max) and T(max) of hydroxysafflor yellow A were increased in the Naodesheng group, compared with 50 mg x kg(-1) C. tinctorius extract group.

OBJECTIVETo observe the biological changes of primary human nasopharyngeal epithelial cells in the early stage of immortalization.

METHODSThe morphological changes of nasopharyngeal epithelial cells were observed by phase contrast microscopy, and the activity profile of senescence-associated beta-galactosidase (SA-beta-Gal) was detected by SA-beta-Gal staining. The expression of p16(INK4a) protein was tested by immunochemical assay, and the life span in vitro of nasopharyngeal epithelial cells was calculated as population doublings. In addition, the expression of Epstein-Barr (EB) virus latent membrane protein 1 (LMP1) was also detected by immunofluorescence staining.

RESULTSMorphologically, cells treated with EB virus and 12-o-tetradecanoyl-phorbol-13-acetate (TPA) formed multi-layer foci, and their cellular life span in vitro was extended (about 155 days of culture). A low percentage of cells (about 4.8%) expressed SA-beta-Gal activity at late primary culture, and did not always express p16(INK4a) protein in the progression of culture.

CONCLUSIONSNasopharyngeal epithelial cells treated with EB virus in cooperation with TPA can pass through the stage of senescence and enter the early stage of immortalization. Some changes of phenotype occur in these cells. Our results provide data for further studying the mechanism of immortalization and the establishment of a human nasopharyngeal epithelial cell line.
