Objective To clarify the role of claudin-4 in endometrial tumorigenesis and explore claudin-4 be as potentially useful agent in the treatment of endometrial carcinoma.Methods The expression of claudin-4 in 62 endonetrioid endometrial carcinoma (EEC),30 atypical hyperplasia endometrial tissue and 60 human normal endometrium was determined using immunohistochemistry and realtime PCR.Ninety female BALB/c mice were transplanted with Ishikawa endometrial cancer cells,which were divided into three groups with different intraperitoneal treatments with cisplatin,paclitaxel and saline solution.After the observation period,the tumors were extracted and stained with monoclonal antibody against claudin-4.The messenger RNA expression of claudin-4 was also detected using real-time PCR.Results Among the EEC samples,34％ (21/62) showed medium staining for claudin-4 and 66％ (41/62) showed intense staining.In atypical hyperplasia group,27％ (8/30) showed weak staining,53％ (16/30) showed medium staining and 20％ (6/30) showed intense staining for claudin-4.Of the normal endometrial tissue,47％ (28/60) showed weak staining and 53％ (32/60) showed no staining for claudin-4.According to real-time PCR,the relative quantity of claudin-4 was 170 ± 12 in EEC group,89 ± 15 in atypical hyperplasia group and 18 ± 3 in normal endometrium.Compared with those in atypical hyperplasia group and normal endometrium group,the protein and mRNA expression of claudin-4 were significantly increased in the group of EEC (all P ＜ 0.05).In the study of Ishikawa xenografts,no significant changes in tumor volume and claudin-4 expression were shown in paclitaxel group compared with that in the control group.Nevertheless,a significant reduction of the tumor growth and a significant decrease in claudin-4 expression were observed in cisplatin group.After cisplatin treatment,the tumor volume was significantly decreased [(0.51 ±0.21) versus (0.73 ±0.12) cm3],and the mRNA expression of claudin-4 was also significantly decreased (153 ± 35 versus 273 ± 27).Conclusion These results demonstrate that claudin-4 is strongly expressed in EEC,which may be a useful biomarker to monitor the effects of chemotherapy in patients with endometrial carcinoma.

The three immediate-early proteins of HSV-1, ICPO, ICP22, and ICP27, have specific and pivotal functions in transcriptional activation and inhibition, multiple regulatory and control processes of viral genes. In this paper, the expression and localization of these three proteins were studied in neuroblastoma cells using biochemical assays, and their possible and potential interactive functions are discussed. The data show that the three proteins are localized in different structures, specifically in the PML-NB-associated structure, which is a specific nuclear structure composed of many protein molecules and bound tightly to the nuclear matrix in neuroblastoma cells. The results suggest that the activating and suppressive functions of ICPs are mostly dependent on their transcriptional and regulatory roles, including the PML-NB-associated structure.

The Sindbis-like virus was first discovered in China in 1986. Its complete genomic sequence consists of more than 11 000 bp encoding more than 3 700 amino acids. It contains a 5' non-transcriptional region (5'-NTR) in a non-structural region, four non-structural proteins (nsP1, nsP2, nsP3, nsP4) regions, capsids in conserved and non-conserved regions and structural E1, E2, E3, 6K regions and a 3' non-transcriptional region (3'-NTR). The Sindbis-IMB was isolated from the blood of a patient suspected to have encephalitis, and was followed by identification and passage. The virus RNA was extracted from virus supernatant in infected cells and the whole genome was divided into 12 fragments; RT-PCR was then performed to amplify the 12 fragments for complete sequencing. The results showed that the whole genomic sequence of Sindbis-IMB consists of 11 717 bp encoding 3 773 amino acids. Homology comparison with other Sindbis-like isolates demonstrated the highest similarity was the YN87448 with a variation of 1% strain isolated in Yunnan Province and the second highest to the SAAR86 strain with a variation of～1.2%.The nucleotide sequence variations were present in non-structural regions, resulting in amino acids K, E, N, R, H, and L in protein sequences in positions 230, 231, 443,781, 1 582, and 1746 in the new isolation respectively. Furthermore, three additional amino acids--glutamic acid, serine and alanine--were noted in nsp4 terminus as compared to the YN87448 isolate.

Objective To explore the mechanisms and the significance of compatibility of Heixiaoyao Powder by observing the effect of Heixiaoyao Powder on mice model of senile dementia induced by scopolamine. Methods Kunming mice were randomly divided into five groups including control group, model group, Heixiaoyao Powder group, Xiaoyao powder group and streamlined formula group, with 10 mice of each group. Scopolamine hydrobromide intraperitoneal injection was adopted to make memory impairment in mice model, and followed by drugs treatment with corresponding decoction of the crude drug 2.314 g /(kg·d). Control group and model group were given normal saline orally once a day, all groups were treated for 10 days continuously. After 6 and 8 days of the administration, water maze test, stair jumping test and darkness avoidance test were conducted to test behavior proficiency, and the activity of acetylcholinesterase (AchE) activity and choline acetyltransferase (ChAT) in brain tissue were tested also. Results Compared with model group, Heixiaoyao Powder group, Xiaoyao Powder group and streamlined formula group could significantly reduce the error number and shorten latency in the water maze test, decrease the time of electrical shocks and prolong the incubation period of time in both stair jumping test and darkness avoidance test, and could increase ChAT activity and lower AchE activity in brain tissue of mice (P<0.01 or P<0.05), especially the effects of Heixiaoyao Powder group. Conclusions Heixiaoyao Powder and its analogous formula have the function of preventing and treating senile dementia.

Objective:To analyze the characteristics of immune cross-reaction between herpes simplex virus type 1 (HSV-1) and HSV-2 in terms of serology and clinical protection aiming to provide data for the control and prevention of diseases caused by the two viruses.Methods:An attenuated HSV-1 strain M3 was used to immunize BALB/c mice. Specific immune responses indicated by the production of neutralizing antibodies were detected. Wild-type HSV-1 and HSV-2 strains were respectively used to infect the mice through different ways 28 d after the immunization to observe the protective immunity in the M3-immunized mice against HSV-1/2 infection.Results:M3 strain could not induce specific neutralizing antibodies against HSV-2. Therefore, viral loads in tissues of the immunized mice increased significantly following different modes of HSV-2 exposure. However, no obvious abnormal clinical manifestations were found and the histopathological damage was only slight inflammatory reaction. In contrast, HSV-1-specific neutralizing antibodies were elicited in the M3-immunizaed mice with significant protective effects against HSV-1 infection.Conclusions:The immune response induced by attenuated HSV-1 strain M3 in mice exhibited immune-protective effects characterized by production of neutralizing antibodies and inhibition of virus proliferation in vivo against wild-type HSV-1 infection. For HSV-2, instead of neutralizing virus in form of antibodies, it featured by more of clinical cross-immunoprotective abilities to control virus growth.

An interaction between the HSV-1 UL25 capsid protein and cellular microtubule-associated protein was found using a yeast two-hybrid screen and β-D-galactosidase activity assays. Immunofluorescence microscopy of the UL25 protein demonstrated its co-localization with cellular microtubule-associated protein in the plasma membrane. Further investigations with deletion mutants suggest that UL25 is likely to have a function in the nucleus.

Pseudoaneurysm often occurred after trauma and infection. It was seen commonly on limb arteries but rarely on vertebral artery. The case was diagnosed two months after trauma. The pulsatile mass and vascular murmur found through preoperative examination confirmed from the vertebral artery. No complication was observed after surgery.
