A mouse model for acute hepatitis B virus (HBV) infection was established by using the hydrodynamical injection of mouse tail vein, in which the immunocompetent BALB/c mice were hydrodynamically injected with a competent replication plasmid pAAV-HBV1.2 having 1.2 fold over-length of HBV DNA. On day 1, 2, 4, 6 and 8 after injection, the levels of HBsAg, HBeAg and HBV DNA in blood serum were detected by using ELISA and fluorogenic quantitative PCR assay (FQ-PCR). And on day 8. HBsAg and HBeAg in liver tissue were assayed by immunohistochemical staining. It was found that HBsAg in blood serum could be detected on day 1 after infection in 14 of 16 mice (85.7%) injected with pAVV-HBV1.2 by using ELISA assay and the peak levels of HBsAg and HBeAg were attained during the first day after injection and then it dropped down gradually up to day 8 following injection. The titer of HBV DNA in blood serum attained its peak on day 2 and maintained a high level later on. On day 8 after injection, its titer was 1.9×10~4 copies/mL. The percentage of HBcAg-positive hepatocytes and HBsAg-positive hepatocytes in liver tissues were 5% and 2% respectively. Thus, by using the hydrodynamic injection with the competent replication plasmid, a mouse model for acute HBV infection is successively developed.

The leading cause of drug withdrawal from market and clinical trials failure is drug-induced liver injury (DILI). Varying clinical, histological and laboratory features of DILI, as well as undefined underlying mechanisms, hinder patients to be diagnosed in the early-stage of the disease and receive effective treatments. Conventional indicators, like serum transaminases and bilirubin, have inevitable limitations referring to sensitive prediction and specific detection of DILI. In order to reduce the occurrence of DILI, researchers have attempted to discover potential biomarkers with higher specificity and sensitivity from blood and urine in recent years. This article aims to review recent advances in biomarkers of DILI.

Objective To investigate the changes of serum thyroxine level in obstructive sleep apnea-hy-popnea syndrome(OSAHS) patients and to assess the role of serum thyroxine in the development of OSAHS. Meth-ods Polysomnography was used to examine the patients with OSAHS and fasting plasma serum thyroxine level were higher in obese OSAHS patients than in obese controls[ (43.56±3.48)cm vs (38.33±3.08)cm,t =4. 258,P < 0.05 ], in non-obese OSAHS patients than in non-obese control group [ (40.50±1.05 )cm vs (36.17±3.13 )cm, t = 3. 146 ,P < 0.05 ] . The levels of FT3 was (6.35±3.15 ) pmol/L in obese OSAHS patients and ( 4.08±2.37 ) pmol/L in control subjects ( t = 2.203 ,P < 0.05 ). That was ( 3.42±0.57 ) pmol/L in non-obese OSAHS patients related with AHI and microarousal index (r = 0. 500, P < 0.05;r = 0.561, P < 0.05 ), and FT4 was also positively with neck circumference( t = 0.489, P < 0.05 ), TSH level was negatively correlated with neck circumference ( t = - 0.500, P < 0.05 ) and was positively correlated with the percentage of body fat ( r = 0.498, P < 0.05 ). Conclu-sions The FT3 levels are significantly higher in the OSAHS patients than that in control subjects, though all FT3 lev-els are normal, suggesting that there are possibility to have abnormal metabolism. At the same time, FT3 level is posi-tively correlated with neck circumference ,suggesting that the OSAHS patients' higher neck circumference is correla-ted with thyroxine.

Objective To explore the efficacy and feasibility of idarubicin combined with medium-dose arabinoside in intensive chemotherapy for acute myeloid leukemia (AML). Methods Fifty remittent patients with induced chemotherapy who underwent the intensive consolidation therapy with medium-dose arabinoside from January 2010 to January 2015 in hematology department of General Hospital of Beijing Military Area were considered as the treatment group. The single arabinoside (2 g/m 2, 1/12 h, d1-3) treatment for 50 cases in the same period were considered as the control group. Two groups were performed with 6 courses sequential. There were 28 males, 22 females in the treatment group, and average age was 27.6 years (18-52 years), with 3 cases of M 1, 27 cases of M2, 8 cases of M4, 12 cases of M5. In the control group, there were 30 males, 20 females, and average age was 26.8 years (16-50 years), with 2 cases of M1, 30 cases of M2, 8 cases of M4, 10 cases of M5. Then the complications and disease-free survival of two groups were observed respectively. Results Follow-up was done until June 2015. In the treatment group, 1 case died of pulmonary infection, 2 cases died of septic shock and 3 cases died of pulmonary infection, 1 case died of septic shock in the control group. The treatment related mortality of both groups were 6 % (3/50), 8 % (4/50), the related relapse rates were 32 % (16/50), 52 % (26/50), the disease-free survival rates were 62 % (31/50), 40 % (20/50) respectively in two groups. Conclusion Compared with the single arabinoside, the intensive consolidation therapy with medium-dose arabinoside and idarubicin for the treatment of AML has gained lower relapse rate and the related mortality, and the DFS rate has been improved significantly, which need further clinical application.

"Framework" and "framework theory" were proposed several decade years ago, and has been widely used in multidisciplinary research. The main purpose of this paper is to identify the concept and connotation of "framework theory" and to discuss the key role of it in Traditional Chinese Medicine (TCM) research, so as to improve integrality and logicality of the theoretic system of TCM. TCM, as a independent science, ought to have the theory and practical framework which can reflect its characteristic and developmental rule. In this paper, we started from the research thought of "framework", introduced the definition, connection and difference between "framework" and "framework theory", analyzed the conditions and methods of establishing a framework, and discussed the applications of "framework" in TCM research.

Objective To evaluate the feasibility of monitoring the gene expression of VEGF165 via the diglycylcysteine (GGC) reporter gene system by reporter probe of 99Tcm-GH. Methods DNA fragments encoding GGC binding motifs were prepared by PCR and positioned at the C end of VEGF165 gene after the linearization of pcDNA3-VEGF165 plasmid. A replication-defective adenovirus vector Ad5-VEGF165GGC motif-internal ribosomal entry site(IRES) -enhanced green fluorescent protein (EGFP) (Ad5-VIE)was constructed, with a cytomegalovirus (CMV) early promoter driving the expression of VEGF165 gene,GGC motif and EGFP, under the aid of an IRFS. A replication-defective adenovirus carrying the Ad5-EGFP was used as the control. Mensenchymal stem cells (MSC) were infected with the recombinant adenovirus at a multiplicity of infection (MOI) from 0 to 100 infectious units (0,10,25,50,100). The cellular uptake of 99Tcm-GH in infected MSC were then studied at 30, 60, 90 and 120 min. VEGF165 was detected by quantitative reverse transcriptase real-time PCR (RT-PCR), Western-blot, and immunohistochemisty. EGFP was observed by RT-PCR and fluorescence microscopy. The correlation analysis was studied between the cellular uptake of 99Tcm-GH and the expression of VEGF165. SPSS 13.0 was applied for statistical analysis. Independent samples t-test, q-test and Pearson correlation coefficient were used. Results After infected with different viral titer of Ad-VIE, the cellular uptake of 99Tcm-GH increased with the increasing virus titer(r2 =0.86, P <0.05), with the peak rate (7.94 ±0.75) % at MOI = 100. In time-dependent uptake study, the cellular uptake rates increased rapidly with the time extension, and the highest uptake occurred at 120 min with the peak uptake rate (7.72 ±0.22)%. The uptake rates of 99Tcm-GH in Ad5-VIE-infected cells were significantly higher than those of Ad5 -EGFP-transfected cells at all time points (t = 15.10- 54.92, all P <0.05). The VEGF165 and EGFP mRNA levels increased with increasing virus titer, and the VEGF165 mRNA correlated well with the EGFP mRNA(r2 = 0. 99, P < 0.05). After infected with different MOI of Ad5-VIE, good relationship was found between the cellular uptake of 99Tcm-GH and the expression of VEGF165protein in MSC(r2 =0.90, P <0.05). Inmunohistochemisty showed VEGF165 protein expressed obviously at Ad5-VIE-infected MSC, and the EGFP was observed by fluorescence microscopy. Conclusions The cellular uptake of 99Tcm-GH in Ad5-VIE-infected MSC are well correlated with the expression of VEGF165 in vitro. The expression of therapeutic gene VEGF165 can be monitored by the GGC peptide expression.
