Objective To determine the utility of apparent diffusion coefficient (ADC) values as an objective method of early detection of traumatic brain injury of the mice models in hippocampus injury.Methods A total of 18 healthy male adult C57/BL6 mice were randomly divided into three groups according to the degree of injury:the mild group,severe group and control group.Conventional images,diffusion-weighted images,ADC were studied.The hippocampal were selected as the interesting area.ADC values were calculated and compared with those in control subjects after 6 h,12 h and 24 h.Student t test was performed for each region to compare the injury groups and the control.Results In control group both sides hippocampal ADC values had no differences(8.65±0.26 and 8.77±0.12) × 10-4 mm2/s,P＞0.05.Abnormalities were detected on ADC values,compared with conventional images in the injury groups.ADC values in mild group and severe group were significantly different from those of control group(6 h ADC values were (8.70±0.50) × 10-4 mm2/s,(6.13± 0.11) × 10-4 mm2/s,and (3.16±0.78) × 10-4 mm2/s in control,mild and severe group respectively),(12 h ADC values (8.23±0.61)× 10-4 mm2/s,(5.92 ± 0.27) × 10-4 mm2/s and (2.64±0.65) × 10-4 mm2/s) and (24 h ADC values (9.01±0.14) × 10-4 mm2/s,(5.99± 0.13)×10-4 mm2/s and (2.58±0.42)×10-4 mm2/s),P＜0.05.Conclusion There are differences among the ADC values on differcnt types of hippocampal brain injury mouse-model.ADC values can identify the degree of damage on brain injury and can detect early craniocerebral injury.

Objective To observe the clinical characteristic and prognosis of primary lung cancer patients with venous thromboembolism (VTE).Methods 589 primary lung cancer patients were selected and divided into VTE group(n =49) and non VTE group(n =540).49 cases with VTE were divided into pulmonary thromboembolism (PTE) group(n =15),including single PTE and PTE combined with deep venous thrombosis(DVT) and DVT group (n =34).Single factor and multiple logistic regression analysis were performed to determine the factors influencing primary lung cancer patients with VTE.Clinical manifestation,time of onset and prognosis of patients with VTE were analyzed.Results 49 patients with VTE included 10 patients(20.4％) with single PTE,34 patients(69.4％) with single DVT and 5 PTE patients combined with DVT(10.2％).D-dimer(OR =1.560,95％ CI =1.018 ～ 2.392,x2 =4.161,P =0.041),interleukin-1 (IL-1,OR =1.846,95％ CI =1.054-3.234,x2 =4.594,P =0.033),tumor necrosis factor (TNF OR =1.486,95％ CI =1.014-2.178,x2 =4.126,P =0.042),adenocarcinoma (OR =2.854,95％CI=1.217-6.695,x2 =5.812,P=0.016) and phase Ⅲ-Ⅳ(OR =2.198,95％CI=1.122-4.305,x2 =5.272,P =0.022) were the factors influencing primary lung cancer patients with VTE.Chest tightness,coughing,accelerated heart rate,swelling and pain in lower limb were common clinical manifestations of primary lung cancer patients with VTE.Most patients with VTE occurred within 3 months after a diagnosis of primary lung cancer.There was no significant difference in the time of onset between PTE group and DVT group(P ＞0.05).As of July 2014,31 cases (63.2％) died,12 cases (24.5 ％) survived,and 6 cases (12.2％) lost in 49 patients with VTE.The median survival time of 49 patients with VTE was 9.5 months.The median survival time of PTE group was 5.8 months,while DVT group was 15.2 months,but no significant difference between them (P ＞ 0.05).Conclusion Increased D-dimer,increased IL-1,increased TNF,adenocarcinoma and phase Ⅲ-Ⅳ could increase the risk of primary lung cancer patients with VTE.There were little typical.clinical symptoms in most patients with VTE,which occurred with in 3 months after a diagnosis of primary lung cancer.They had high mortality and needed to take early diagnosis and treatment through auxiliary examination.

Objective:To evaluate the clinical value of radioactive nuclide strontium chloride (89SrCl2) combined with 99Tc-MDP in treating patients with breast cancer and osseous metastasis. Methods:A total of 80 patients with breast cancer and experiencing bone pain from osseous metastasis were randomly categorized into three groups. 22 patients were treated with 99Tc-MDP (99Tc-MDP group), 30 were treated with 89SrCl2 (89SrCl2 group), and 28 were treated with the combination therapy of 89SrCl2 and 99Tc-MDP (combination group). The analgesic effect, remission of bone metastases, and quality of life of patients in the three groups were observed before and after treatment. Side effect was also monitored. Results:In the combination group, the overall pain relief rate and the increase rate of life quality score were 92.9%(26/28) and 78.6%(22/28), respectively. The combination group was statistically significantly different from the two single-treatment groups (P<0.05). The effective rate of metastatic lesions was 46.4%(13/28) in the combination group, which was significantly higher than that in the 99Tc-MDP group (18.2%, 4/22;P<0.05). The effective rate of metastatic lesions was not significantly different between the combination and 89SrCl2 groups (33.3%, 10/30) (P>0.05). Conclusion:The treatment of 89SrCl2 com-bined with 99Tc-MDP can increase the analgesic effect and significantly improve the curative effect without overt side effects in patients with breast cancer and bone metastasis.

Objective To clone human vacuolar protein sorting 4A gene(hVPS4A)and to construct its eukaryotic expressive plasmid.Methods Primers were designed to amplify the full length hVPS4A by PCR using cDNA of Huh7 cell as a template,then the target DNA was inserted into the eukaryotic vector pRK5.The recombinant plasmid was confirmed by PCR,restriction enzyme digestion and DNA sequencing.Results A 1 300 bp fragment was successfully amplified by PCR from the cDNA of Huh7 cells.Af-ter recycled,purified and ligated with the vector pRK5,the recombinant plasmid was transformed into E.coli DH5α.The positive re-combinant plasmid identified by PCR was selectred and digested by EcoRⅠto get a 5 900 bp fragment;and two fragments including 4 600 bp and 1 350 bp were obtained using EcoRⅠand HindⅢ digestion;the size of these two fragments were consistent with the pRK5 target fragment and the inserted hVPS4A as expected.Moreover,DNA sequencing results confirmed that the inserted frag-ment was in accordance with the hVPS4A reference sequence.Conclusion The eukaryotic expression vector containing hVPS4A gene is constructed successfully,which provides the condition for further study on the hVPS4A biological functions.

This study examined the anti-hepatitis B virus (HBV) effect of wild-type (WT) vacuolar protein sorting 4B (VPS4B) and its dominant negative (DN) mutant VPS4B-K180Q in vivo in order to further explore the relationship between HBV and the host cellular factor VPS4. VPS4B gene was amplified from Huh7 cells by RT-PCR and cloned into the eukaryotic expression vector pXF3H. Then, the VPS4B plasmid and the VPS4B-K180Q mutation plasmid were constructed by using the overlap extension PCR site-directed mutagenesis technique. VPS4B and HBV vectors were co-delivered into mice by the hydrodynamic tail-vein injection to establish HBV vector-based models. Quantities of HBsAg and HBeAg in the mouse sera were determined by ElectroChemiLuminescence (ECL). HBV DNA in sera was measured by real-time quantitative PCR. Southern blot analysis was used to assay the intracellular HBV nuclear capsid-related DNA, real-time quantitative PCR to detect the HBV-related mRNA and immunohistochemical staining to observe the HBcAg expression in the mouse liver tissues. Our results showed that VPS4B and its mutant VPS4B-K180Q could decrease the levels of serum HBsAg, HBeAg and HBV-DNA. In addition, the HBV DNA replication and the mRNA level of HBV in the liver tissues of treated mice could be suppressed by VPS4B and VPS4B-K180Q. It was also found that VPS4B and VPS4B-K180Q had an ability to inhibit core antigen expression in the infected mouse liver. Furthermore, the anti-HBV effect of mutant VPS4B-K180Q was more potent than that of wild-type VPS4B. Taken together, it was concluded that VPS4B and its DN mutant VPS4B-K180Q have anti-HBV effect in vivo, which helps develop molecular therapeutic strategies for HBV infection.

BACKGROUND: Compared to other preparation method, chemical extraction can almost removed all cellular components,reduce the possibility of immunological rejection, and remain the integrality of nerve graft. However, there are still problems need to be explored.OBJECTIVE: To investigate the optimal condition of acellular nerve graft using Trito X-100 and sodium deoxycholate as extracting agent.DESIGN, TIME AND SETTING: Randomized grouping, controlled cytology observation. The experiment was performed at the Department of Stomatology, Affiliated Hospital of Binzhou Medical University, from February to June 2009.MATERIALS: Fifteen New Zealand white rabbits, aged 3-4 months, weighing 2.5-3.0 kg. Triton X-100 and sodium deoxycholate were provided by Sigma Company, USA.METHODS: The bilateral facial nerve were obtained from rabbits, and removed the adipose tissue and epineurium of the nerve surface under the surgery microscope, then divided these nerves into 66 segments, with each length of 10 mm. The 66 neurons were randomly divided into 11 groups, with 6 neurons in each group. Except the control group, all neurons were placed into Petri dish for 12 hours bathing using distilled water at room temperature, then 5 groups of which were cultured with Triton X-100 for 12,24, 36, 48, and 60 hours, oscillation at room temperature; the remained 5 groups were cultured with 3% Triton X-100 for 12 hours,followed by 4% sodium deoxycholate for 12 hours, repeated for 1-5 cycles.MAIN OUTCOME MEASURES: Haematoxylin-eosin staining; degrees of decellularization and integrality of fiber pipe.RESULTS: Only use Triton X-100 to deal with the nerve of New Zealand white rabbits, even if 60 hours, could not to remove all the cellular components, and the basement membrane of Schwann cells were greatly destroyed. After 2 cycles treatment of Trito X-100 combined with sodium deoxycholate, cellular components and myelin sheath of nerve fibers and axons were removed effectively, and basement membrane of Schwann cell was remained, with epineurium and perineurium could be seen.CONCLUSION: Oscillation accompanied by 2 cycles treatment of Trito X-100 and sodium deoxycholate can obtain acellular nerve graft by removing cellular components completely, and reserving integrated basement membrane of Schwann cells.

Objective To investigate the effect of human interferon-beta (IFN-β) gene engineered human mesenchymal stem cells (hMSC) in the treatment of human prostate cancer xenograft in nude mice.Methods An adenovirus vector containing human IFN-β gene was constructed and transfected into hMSC in vitro.IFN-β-expressing mesenchymal stem cells (IFN-β-hMSC) were labeled with 4,6-diamidino-2-phenylindole (DAPI).The human prostate cancer cell line PC-3 were injected into the flank or axillary of severe combined immunodeficiency (SCID) mice subcutaneously to establish human prostate cancer xenograft models.IFN-β-hMSC were injected into the tail vein of mice bearing human prostate cancer xenografts.The tumors,livers,lungs,spleens and kidneys were harvested.Frozen sections and paraffin sections were used to observe the distribution of IFN-β-hMSC in vivo by fluorescence microscope.Mice were divided into seven groups of six animals randomly,IFN-β-hMSC (2 × 106,2 × 105 ) as treatment group,Ad-hMSC,unmodified hMSC,Ad-IFN-β,Recombinant IFN-β,and NS as control group.The weight of the tumor and the survival time of mice were observed to evaluate the experimental efficacies of IFN-β-hMSC in the treatment of prostate cancer. Results IFN-β-hMSC with blue nuclei were distributed extensively in the tumors,but no blue nucleus was seen in the livers,lungs,spleens and kidneys.After treating,the weights of the tumour masses from mice were (1.35 ±0.28) g,(1.43±0.41) g,(3.49 ±0.25)g,(3.58±0.30)g,(3.30 ±0.24) g,(3.32 ±0.25) g,(3.32 ±0.47) g in the IFN-β-hMSC (2 ×106),IFN-β-hMSC (2 ×105),Ad-hMSC,unmodified hMSC,Ad-IFN-β,Recombinant IFN-β,and NS group,the median survival time from mice were 91 d,87 d,57 d,59 d,62 d,61 d,61 d in the IFN-β-hMSC (2 × 106),IFN-β-hMSC (2 × 105),Ad-hMSC,unmodified hMSCs,Ad-IFN-β,Recombinant IFN-β,and NS group,respectively.Injection of IFN-β-MSC can significantly reduce tumor weight and increase animal survival compared with controls ( P ＜ 0.05 ). Conclusion IFN-β-hMSC can migrate to prostate cancer microenviroment in vivo,and injection of IFN-β-MSC can significantly reduce tumor weight and increase animal survival.
