OBJECTIVETo investigate the relation of heparanase gene and angiogenesis with the progress of gastric carcinoma (GC).
METHODSExpression of heparanase mRNA in 52 GC tissue was detected by in situ hybridization assay. Microvessel density (MVD) was examined by immunohistochemical method. MVD and heparanase mRNA expression were analysed with their relation to histological grade, invasion depth,lymph node metastasis and organ metastasis.
RESULTSMVD was 73.2 +/- 22.8 in 25 (48.1%) tissue with positive heparanase mRNA. It was 44.8 +/- 11.9 in 27 (51.9%) tissues with negative heparanase mRNA, between which the difference was significant (P < 0.001). MVD and heparanase mRNA expression were related with lymph node metastasis and depth of serosal invasion in GC (P < 0.005).
CONCLUSIONHeparanase, being related to angiogenesis in gastric cancer, promotes growth, invasion and metastasis. Heparanase mRNA expression is an important predictor of the biological behavior of human gastric carcinoma.

To investigate the resources of medicinal plant, such as wild Apocynum, supervised classification based on Principal Component Analysis (PCA) and texture feature were used to monitor wild medicinal plants from image captured by ZY-3 and World-view-2 and compare which satellite Image are more appropriate to monitor the wild medicinal plants. The research results shows that: for more complex growth conditions wild medicinal plants Apocynum, high-resolution images Worldview-2 is more suitable for its remote identification, the low-resolution satellite ZY-3 can only recognizes the wild medicinal plants which distributed intensively. If the study target distribution is more intensive and larger scale, and cultivated type medicinal plants, the use of satellite ZY-3 in low resolution remote sensing data to identify the target can be a good choice, it is not necessary to buy high-resolution data, in order to avoid waste of expenditure, for the scattered distribution, the high-resolution satellite imagery data may be indispensable to identify targets.

To explore the role of regulatory peptides in the secretion of bronchial epithelial cells (BECs), we observed the effects of four peptides, i.e.vasoactive intestinal peptide (VIP), epidermal growth factor (EGF), endothelin-1 (ET-1), and calcitonin gene-related peptide (CGRP), on the secretion of ILs from unstimulated or O3-stressed BECs. The results of the experiments showed that VIP exerted an inhibitory effect on the secretion of IL-1 and IL-8 from unstimulated and O3-stressed BECs, VIP also decreased the secretion of IL-5 from O3-stressed BECs; EGF promoted secretion of IL-1 and IL-8 from unstimulated BECs, but decreased the secretion of ILs from O3-stressed BECs; ET-1 and CGRP enhanced the secretion of IL-1, IL-5, and IL-8 from unstimlated BECs, CGRP also increased the secretion of ILs from O3-stressed BECs. The results obtained demonstrate that intrapulmonary regulatory peptides modulate the secretion of ILs from BECs, and may play an important part in transduction of inflammatory signals.

Leucine-rich glioma inactivated-1 (LGI-1) antibody-mediated encephalitis is a subtype of autoimmune encephalopathy associated with antibody against neuronal plasma membrane proteins ADAM23 binding protein LGI-1. The main symptoms of this disease are characterized by seizures, faciobrachial dystonic seizures, cognitive deficits, neuropsychiatric disturbances, and intractable hyponatremia. The disease diagnosis mainly depends on positive expression of LGI1 antibody in serum or cerebrospinal fluid. Early diagnosis combined with immunotherapy can apparently improve prognosis and reduce the risk of disease recurrence. However, due to the delayed diagnosis or misdiagnosis, the patients always result in poor prognosis. The objective of this review is to raise awareness of LGI-1 antibody encephalitis. Thus, in this study, we summarize the etiology, pathogenesis, clinical presentations, imaging, diagnosis, treatments and prognoses of this disease based on the latest research progress to improve the diagnosis and curative effect.

OBJECTIVETo evaluate the efficacy and safety of telbivudine (LDT) versus entecavir treatments in hepatitis B e antigen (HBeAg)-positive chronic hepatitis B (CHB) patients.
METHODSEighty HBeAg-positive compensated CHB patients with HBV DNA more than 6 log10 copies/ml and serum ALT 2 x ULN were divided into two groups: a telbivudine treatment group, and a entecavir treatment group. HBV DNA, ALT and HBeAg were surveyed at baseline and at 12 and 24 weeks. The efficacy and safety of the two nucleoside analogues were assessed at 12 and 24 weeks.
RESULTSUndetectable serum HBV DNA levels of the telbivudine group (50% and 80%) were similar to those of the entecavir B group (50% and 70%) according to the polymerase-chain-reaction assay at week 12 and 24. There were no significant differences in the normalization of alanine aminotransferase levels between the two groups at week 12 and 24 (52.5% vs 60.0%, 77.5% vs 75.0%). The mean reductions in serum HBV DNA from the baseline levels at week 12 and 24 were similar between the two groups [5.27 vs.5.36, 6.49 vs.6.18 log (on a base-10 scale) copies per milliliter]. More patients in the telbivudine group had HBeAg seroconversion at week 12 than those in the entecavir group (20.0% vs 5.0%, P = 0.043); however, there was no significant difference between the two groups at week 24 (27.5% vs 17.5%). No adverse reactions were found in either group.
CONCLUSIONThere was no significant difference in HBV DNA undetectable rates and the ALT normalization rates between the two groups in a short-term therapy (24 weeks), but the telbivudine group had a higher rate in HBeAg seroconversion than that in the entecavir group at week 12.
