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 assess the efficacy and safety of Saw Palmetto Extract Capsules in the treatment of benign prostatic hyperplasia (BPH).

METHODSWe conducted a multi-centered open clinical study on 165 BPH patients treated with Saw Palmetto Extract Capsules at a dose of 160 mg qd for 12 weeks. At the baseline and after 6 and 12 weeks of medication, we compared the International Prostate Symptom Scores (IPSS), prostate volume, postvoid residual urine volume, urinary flow rate, quality of life scores (QOL), and adverse events between the two groups of patients.

RESULTSCompared with the baseline, both IPSS and QOL were improved after 6 weeks of medication, and at 12 weeks, significant improvement was found in IPSS, QOL, urinary flow rate, and postvoid residual urine. Mild stomachache occurred in 1 case, which necessitated no treatment.

CONCLUSIONSaw Palmetto Extract Capsules were safe and effective for the treatment of BPH.

OBJECTIVETo study the changes in pulmonary function and fractional exhaled nitric oxide in exhaled breath (FeNO) in asthmatic children who have different responses to regular treatment.

METHODSA total of 52 asthmatic children who had a good compliance with regular stepped control treatment were selected as subjects. They were followed up every three months to evaluate the asthma control level, pulmonary ventilation function, and FeNO for 9 months. Besides, medications for asthma control were recorded.

RESULTSAt three follow-up points (months 3, 6, and 9), the percentage of asthmatic children who used the first or the second level of control treatment in the stable group (with stable response to the treatment) was significantly higher than in the unstable group (with unstable response to the treatment) (P<0.05), while the percentage of asthmatic children who used the third level of control treatment in the stable group was significantly lower than in the unstable group (P<0.05). At the three follow-up points, the stable group had a significantly higher ratio of forced expiratory volume in 1 second to forced vital capacity (FEV1/FVC) than the unstable group (P<0.05); at the 3-month and 9-month follow-up points, the stable group had a significantly higher percentage of predicted maximum mid-expiratory flow (MMEF%) than the unstable group (P<0.05); at the initial evaluation and 3-month follow-up point, the stable group had a significantly higher FeNO than the unstable group (P<0.05).

CONCLUSIONSContinuously monitoring FEV1/FVC, MMEF% and FeNO is useful in the early evaluation of the responses to treatment in children with asthma.

OBJECTIVETo investigate the treatment effect of autologous HBsAg-loaded dendritic cells (DCs) on patients with chronic hepatitis B (CHB).

METHODSMonocytes were isolated from fresh peripheral blood of 19 CHB patients by Ficoll-Hypaque density gradient centrifugating and cultured with plastic -adherence method. DCs were induced and proliferated from the monocytes with granulocyte-macrophage clony stimulating factor (GM-CSF) and interleukin-4 (IL-4) for seven days. After being incubated with HBsAg for two hours, DCs were injected to patients subcutaneously twice at the interval of two weeks. HBV DNA level, alanine aminotransferase (ALT) level, and HBV markers in the serum of patients were tested every two months.

RESULTS11 of the 19 (57.9%) patients responded to DC-treatment clinically. The rates of HBeAg clearance and HBeAg/anti-HBe seroconversion were 52.6% (10/19) and 26.3% (5/19) respectively, and the copies of HBV DNA decreased by 10(1.77 2.39) (t = 3.13, P < 0.01). Two patients who were treated in combination with lamivudine had complete clinical response. There was no difference in the trial effect between the DC treatment and the other two antiviral methods, and in the efficient rate between the patients whose ALT levels were high before treatment and those whose ALT levels were normal.

CONCLUSIONThe autologous HBsAg-loaded DCs can effectively suppress HBV replication, reduce virus load in serum, eliminate HBeAg and promote HBeAg/ anti-HBe seroconversion. The patients whose ALT levels are high or normal can response clinically to DCs treatment. DCs in combination with lamivudine can eliminate virus more effectively.
