0.05).The serum PICP of tubercular meningitis children after 4 neeks glucocorticoid therapy (108.85?46.13) ?g/L was significantly lower than that in control group((154.38)?47.98) ?g/L and glucocorticoid- pretreatment (152.99?44.78) ?g/L (P

Objective To establish a model of multiple organ dysfunction syndrome in the elderly (MODSE) by intraperitoneal injection of different doses of zymosan, and to compare the multiple organ dysfunction syndrome (MODS) in adult and in the elderly rats. Methods Adult and senile rats, injected with different doses of zymosan intraperitoneally were examined for the changes in the function and morphology of the vital organs, including heart, liver, brain, lungs, and kidneys using blood gas and biochemistry analysis and histopathological examination methods. Results Compared with the normal controls of the adult and the elderly rats, the blood gas and blood biochemistry changed in different degrees in the different dosed zymosan groups. Pathological changes were also found in the vital organs including lungs, heart, liver, brain, kidneys, erc in the experimental groups. Under the same concentrations of zymosan, the reductions in respiratory, cardiac and renal functions in the senile groups were much more severe than those in the corresponding adult group. In the similar degree of model duplication, the senile rats had the tendency to die later than the adult rats. Conclusions Zymosan can be used in both elderly and adult rats to induce MODS model, and the best dosage for MODSE was 0.Sg/kg injected peritoneally. The model would hopefully be used in the study of mechanisms and the therapeutics on MODSE.

AIM:To investigate the clinical effect of anti-vascular endothelial growth factor (VEGF) drugs combined with laser photocoagulation for diabetic macular edema (DME).METHODS: Totally 94 patients (141 eyes) with DME from June to December 2015 in our hospital were selected and randomly divided into combined group of 47 cases (68 eyes, ranibizumab combined with laser therapy) and the control group of 47 cases (73 eyes, laser treatment).The levels of best corrected visual acuity (BCVA), macular central retinal thickness (CRT), total macular volume (TMV) and macular edema level were compared between the two groups at different time after treatment.RESULTS: The mean values of BCVA in the combined group were higher than those in the control group at 2, 6 and 12wk, and the difference was statistically significant (P<0.05).At 2, 6 and 12wk after treatment, the CRT and TMV values of the combined group were lower than those of the control group, the difference was statistically significant (P<0.05).After treated for 12wk, patients with macular edema of combined group was 80.9% in mild level, 17.7% in moderate level, 1.5% in severe level, those of the control group was 60.0%, 31.5%, 5.5%, the difference between the two groups was statistically significant (P<0.05).CONCLUSION: The effect of anti-VEGF drugs combined with laser therapy for DME patients is better than that of single laser therapy alone.

OBJECTIVETo investigate the relationship of serum metalloproteinase with the severity of liver fibrosis and inflammation.

METHODSA total of 88 patients with HBV-related liver fibrosis and early cirrhosis were enrolled from six hospitals. Serum fibrosis markers including hyaluronic acid (HA), IV collagen (IV-C), aminoterminal propeptide of type III procollagen (PIIIP), laminin (LN), matrix metalloproteinases (MMP) 1, 2, 9 and tissue inhibitors of metalloproteinase (TIMP) 1, 2 levels were determined. Liver biopsies were assessed according to a modified Scheuer and Chevallier's scoring system.

RESULTSSerum TIMP1 (r=0.540) and MMP2 (r=0.314) were correlated positively with the degree of hepatic fibrosis, whereas serum MMP1 (r=-0.495) was correlated negatively. By receiver operating curve analysis (ROC), the sensitivity to distinguish the fibrosis stage 2 from stage 1 was 90.5% and the specificity was 52.0% if the cut-off value of MMP1 was 13.96 ng/ml, and the sensitivity was 91.6% and the specificity was 64.0% if the cut-off value of TIMP1 was 76.84 ng/ml. The sensitivity to distinguish cirrhosis (stage 4) from fibrosis (stage 3) was 70.7% and specificity was 80.9% if the cut-off value of MMP1 was 6.86 ng/ml, and the sensitivity was 60.5% and the specificity was 92.3% if the cut-off value of TIMP1 was 210.04 ng/ml.

CONCLUSIONSerum TIMP1, MMP1, MMP2 levels and TIMP1/MMP1 ratio could be used as serum fibrosis markers.

OBJECTIVESTo further assess the clinical antifibrotic efficacy of Cpd 861 on chronic hepatitis B related fibrosis and early cirrhosis using a randomized, double blind, and placebo controlled clinical trial.

METHODSTotal 136 patients with HBV-related fibrosis and early cirrhosis were allocated randomly into Cpd 861 treatment group and placebo group for 24 weeks treatment. Serum fibrosis markers including hyaluronic acid (HA), IV collagen (IV-C), amino terminal propeptide of type III procollagen (PIIIP), and laminin (LN) and serum MMP1, 2, 9, TIMP1, 2 level were determined before and after 24 weeks treatment. Liver biopsies before and after 24 weeks of treatment were assessed according to modified Scheuer and Chevallier's scoring system.

RESULTSTotal 52 patients in Cpd 861 treatment group and 50 patients in placebo-controlled group completed the 6 months. ALT level decreased from 68.2 U/L+/-68.6 U/L to 45.9 U/L+/-26.1 U/L, AST level decreased from 60.4 U/L+/-62.6 U/L to 46.7 U/L+/-39.0 U/L (P < 0.05) after 24 weeks treatment, whereas there was no significant change in placebo group (ALT: 65.3 U/L+/-48.3 U/L to 85.4 U/L+/-115.5 U/L; AST: 60.4 U/L+/-44.6 U/L to 77.6 U/L+/-89.6 U/L, P > 0.05). Serum fibrosis markers, including HA, IV-C, PIIIP, and LN were decreased after treatment, but there is no statistically significant compared with placebo group. Compared with placebo group, serum TIMP1 and MMP9 level decreased significantly (TIMP1 172.0 ng/ml+/-79.6 ng/ml vs 133.5 ng/ml+/-66.8 ng/ml; MMP9 116.1 ng/ml+/-88.2 ng/ml vs 80.4 ng/ml+/-79.0 ng/ml), and the ratio of TIMP1/MMP1 (48.3+/-96.3 vs 19.9+/-28.0) were also decreased after 861 treatment. In patients treated with Cpd 861, hepatic inflammatory score (from 14.0+/-6.0 to 10.2+/-6.1), fibrosis score (from 11.9+/-6.5 to 8.2+/-4.5), and relative content of collagen (from 18.9%+/-9.5% to 14.9%+/-8.4%) decreased significantly. In contrast, there was no significant change in placebo group. The reversal (fibrosis score decrease > or = 2) rate of fibrosis in Cpd 861 group was 38.9% in S2, 53.3% in S3 (precirrhotic) and 78.6% in S4 (cirrhosis), significantly higher than those in placebo group (14.3%, 25.0%, and 41.7%, respectively). The overall reversal rate was 52.0% in Cpd 861 group, and 20.0% in placebo group (P < 0.05). No serious adverse effects were observed during Cpd 861 treatment.

CONCLUSIONLiver fibrosis and early cirrhosis due to HBV infection in man could be definitely reversed by herbal remedy Cpd 861.

Objective To investigate the effect of p53 protein on the nerve function of rats with acute cerebral ischemia-reperfusion by electro-acupuncture pretreatment. Methods A total of 72 male Sprague-Dawley rats were randomly divided into sham group(n=24),model group(n=24) and electroacupuncture pretreatment group(n=24).Each group was equally divided into two hours and 72 hours subgroups. The neurological behavior was assessed with modified Neurological Severity Score (mNSS). HE staining and TUNEL assay were used to observe the injury and cell apoptosis in ischemic brain,and Western blot-ting was used to detect the expression of p-p53(ser392),p53 and microtubule associated protein 1 light chain 3 (LC3)II in ischemic area. Results Compared with the model group,the mNSS scores,the injury of brain tissue,the number of TUNEL-positive cells, and the level of p-p53 and LC3II decreased (P<0.05) in the electroacupuncture pretreatment group.Two hours after reperfusion,there was no significant difference in the level of p53 between the model group and the electroacupuncture pretreatment group(P>0.05),however,72 hours after reperfusion,the level of p53 decreased in the electroacupuncture pretreatment group(P<0.05). Conclusion Electroacupuncture pretreatment can improve neurological deficit in cerebral ischemia-reperfusion injury rats,which may be related to the involvement of p53 protein in autophagy and apoptosis.

In order to study the tumor suppression effect of p53 with CMV enhancer and hTERT promoter mediated by human-derived vector pHrn in liver cancer cell Bel-7402, report plasmid pchEGFP, tumor suppressor plasmids pchp53Arg and pchp53Pro were constructed by inserting expression cassette CMVe+hTERTp+EGFP, CMVe+hTERTp+p53Arg and CMVe+hTERTp+p53Pro into pHrn respectively. 24 h after cell transfection by lipofectamine 2000, GFP expression pattern was analyzed through fluorescence microscope and flow cytometry; RT-PCR and Western blot were taken to study the p53 expression pattern. The cell apoptosis by Hoechst 33258 and Annexin V-FITC/PI staining was also studied. Results show that the expression of GFP and p53 protein in Bel-7402were detected, but apparent cell apoptosis could not be found. The recombinant p53 mediated by human-derived vector could express in Bel-7402, but no significant tumor suppression effect was detected, which might result from the down regulation effect of the wild type p53 on hTERT promoter.
