Objective To observe the effects of wild jujube seed decoction(WJSD) on ultrastructure and astrocytes expression in the brain cortex of old model rats with blood-deficiency and Yin and sleep deprivation(SD)after SD. Methods Ultrastructural changes in cortical parts of the experiment rat were observed by transmission electron microscopy , immunohistochemical staining was used to detect star-shaped glial cells marker-glial fibrillary acidic protein(GFAP) expression after SD induced by made-self multiple platform method (MMPM), senescence induced by D-galactose, and Yin and blood-deficiency induced by cyclophosphamide and hydrocortisonum. Results Compared to environmental control group((9.8 ± 2.5), (0.11 ± 0.02) ) , syndrome model group (( 20.4 ±4.4), (0.20 ±0.011) ) rats had obvious ultrastructural changes and stronger expression of GFAP in cortical parts (t = 7.63,3.18, P ＜ 0. 01), while those of W J SD of high and low dose group ((14.4 ± 3.9), (15.5 ± 6.4),(0.14 ±0.02)(0.14±0.02)) rats showed weaker(t=6.32,5.24,2.31,2.45, P＜0.05). Conclusion WJSD of large and small lose group could improve the rats neurons pathological changes,WJSD downward adjusting the expression of GFAP may be one of the mechanisms of treatment on insomnia with blood-deficiency and Yin in the old.

OBJECTIVETo explore the stimulation of human hepatic stellate cells by Cytochrome P4502E1-mediated oxidative stress.

METHODSHepG2-line was transfected with human CYP2E1 plasmid (HepG2/CYP2E1) and empty plasmid (HepG2/PCI) respectively. The CYP2E1 expression was evaluated with RT-PCR and Western blot. MDA was measured in culture medium of HepG2 cell lines. LX2 was co-incubated with HepG2/CYP2E1, HepG2/PCI and HepG2 respectively. The level of hydroxyproline in culture medium was examined in 48 hours and the cells were lysated and total RNA and protein were extracted. COL-1 and MMP2 mRNA levels were detected by RT-PCR and analyzed semi-quantitatively. PICP proteins were measured by ELISA. Zymography was performed to investigate MMP2 enzymatic activities.

RESULTS(1) MDA from the HepG2 which (HepG2/CYP2E1)express human CYP2E1 (6.51+/-0.25) was significantly higher than that from the HepG2 which do not (HepG2/PCI) express human CYP2E1 (3.07+/-0.29) and HepG2 alone (2.57+/-0.29). (F=22.66, all P<0.01). (2) After co-incubated for 48 hours,the level of hydroxyproline in culture medium (35.24+/-3.52) excreted from CYP2E1/LX2 could significantly increase (F=58.89, P is less than 0.01). PICP protein (540.01+/-11.38) excreted from CYP2E1/LX2 was significantly increased (F=124.97, P<0.01). Zymography showed MMP2 gene expression and enzymatic activities of MMP2 had no difference among the groups (F=0.29, P>0.05) (F=0.33, P>0.05).

CONCLUSIONSCYP2E1 derived oxidative stress mediated stimulation of collagen I synthesis by hepatic stellate cells. Hydroxyproline excreted by LX2 was increased by CYP2E1. COL-1mRNA had no difference among the groups (F=0.73, P>0.05).

OBJECTIVETo examine the expression of cytochrome P450 related genes in oral submucous fibrosis tissue and to investigate the possible role of the genes in pathogenesis of oral submucous fibrosis (OSF).

METHODSBuccul mucosa tissues were obtained from OSF patients in early, medium and advanced stages, with each stage including 10 patients. Normal buccul mucosa tissues were collected from 10 patients undergoing oral and maxillofacial surgery as control. Oral submucous fibrosis-related genes were analysed by cDNA chips, and the results were submitted to the gene network database. Differentially expressed genes related to the pathway of CYP metabolism were indentifyed by the database analysis. Reverse transcription-polymerase chain reaction (RT-PCR) was used to verify the results from cDNA chips by increasing sample volume.

RESULTSThere were eight genes [CYP2B6, CYP2C18, CYP2F1, CYP3A5, microsomal glutathione S-transferase 2 (MGST2), alcohol dehydrogenase (ADH), UDP glucuronosyl transferase 2B15 (UGT2B15), ADH1C] which were related to the pathway of CYP metabolism. These genes were low expressed in all stages of OSF (P < 0.001).There were no differences in genes expression among the three stages of OSF (P > 0.05).

CONCLUSIONSThere were down-regulated genes related to the pathway of CYP metabolism in oral submucous fibrosis tissue. The ability of the pathway of CYP to metabolize and clear betel nut ingredients was reduced in OSF patients, which may play a role in the pathogenesis of OSF.

OBJECTIVETo study the effect of Feiji Recipe (FR) intervening indoleamine 2,3-dioxygenase (IDO) induced immune escape on the murine model of Lewis lung carcinoma. Methods Totally 48 C57BL/6 mice inoculated with Lewis lung cancer cells transfected with human (enhanced green fluorescent protein,EGFP)-IDO gene were divided into four groups according to radom digit table, i.e., the model group (administered with normal saline by gastrogavage) , the Chinese medicine group (treated with FR Decoction at the daily dose of 100 mg/g by gastrogavage), the 1-methyl-D-trytaphan (1-MT) group (administered with 1-MT mixed liquor at the daily dose of 100 mg/kg by gastrogavage), and the Paclitaxel group (treated with Paclitaxel at the daily dose of 15 mg/kg by peritoneal injection), 12 in each group. The intervention was started from the 2nd day of modeling. The survival time was observed in 24 of them. Ratios of CD4+ CD25+ FoxP3+ regulatory T cells (Treg) in the spleen were detected in the rest 24 mice by flow cytometry respectively.

RESULTSCompared with the model group, the survival time was significantly prolonged in the Chinese medicine group and the 1-MT group (P < 0.01); ratios of Treg cells remarkably decreased in the Chinese medicine group, the 1-MT group, and the Paclitaxel group (P < 0. 01). Compared with the Paclitaxel group, the survival time was significantly prolonged in the Chinese medicine group and the 1-MT group (P < 0.01); ratios of Treg cells decreased significantly in the 1-MT group (P < 0.05).

CONCLUSIONFR could inhibit the proliferation of lung cancer cells and immune eseape, improve the immune function, and prolong the survival of tumor-bearing mice.

Traditional Chinese medicine (TCM) is considered an important complementary therapy with beneficial effects for cancer patients. Elderly patients with non-small-cell lung cancer (NSCLC) are a complex patient group with increasing co-morbidity and shrinking physiological reserve, and may derive substantial benefit from the supportive aspects of TCM. Researchers from Shanghai Longhua Hospital found that qi and yin deficiency is a common syndrome in patients with stage III or IV lung cancer. This project was designed to study the combination of single-agent chemotherapy with TCM methods of benefiting qi and yin in elderly patients with advanced NSCLC.

OBJECTIVETo analyze the correlation between myocardial ischemia and carotid atherosclerosis in hypertensive patients.

METHODSThe clinical data were collected from 85 hospitalized hypertensive patients admitted between May 2005 and September 2008 without the complication of coronary artery disease as confirmed by cardiac computed tomographic angiography (CTA). According to the results of treadmill exercise test, the patients were divided myocardial ischemia group and ischemia-free group. Univariate and multivariate analyses were used to screen the risk factors of myocardial ischemia. The correlations were analyzed between myocardial ischemia, common carotid artery intima-media thickness (IMT), Crouse score of the carotid plaque, thickness of the intraventricular septum and left artrium. The receiver operating characteristic (ROC) curves were used to evaluate the sensitivity and specificity of IMT and Crouse score in predicting the presence of myocardial ischemia in hypertensive patients.

RESULTSCarotid plaque formation was identified as the major risk factor of myocardial ischemia in hypertensive patients (OR=4.982, P=0.004). The incidence of myocardial ischemia in the hypertensive patients with carotid plaques was significantly higher than that in the patients without the plaque (Chi2=9.317, P=0.002). Myocardial ischemia in hypertensive patients was positively correlated to the thickness of the intraventricular septum (r=0.362, P=0.001) and left artrium (r=0.298, P=0.009), and the IMT of the common carotid artery was positively correlated to the thickness of the intraventricular septum (r=0.231, P=0.045). The area under cure (AUC) of the ROC curve of Crouse score was 0.726-/+0.061 in predicting the presence of myocardial ischemia in the hypertensive patients (P=0.001), and that of IMT was 0.682-/+0.061 (P=0.006).

CONCLUSIONCarotid plaque formation is the major risk factor of myocardial ischemia in hypertensive patients and shows a positive correlation to the onset of myocardial ischemia, but both the common carotid artery IMT and the Crouse score of the carotid plaque are not accurate markers for predicting myocardial ischemia in patients with hypertension.

OBJECTIVETo summarize the clinical characteristic and outcome of digital gigantism of the foot.

METHODSRetrospectively analyze the clinical documents of cases of digital gigantism of the foot. Twelve 12 cases with 13 feet in this study included 8 male and 4 female with an average 4.6-years-old. All the deformities were found at birth. Multiple toes involved were more than single toe, and tibial toe involved more than fibular. Forefoot was enlarged. All the phalanges involved and partial metatarsal bones were enlarged. Marked increase in subcutaneous fat was found in all cases in the operation which infiltrated interossei and articular capsules. The appearance of the nerves and its branches in the foot were normal and fat infiltrating was not discovered. The operation types included debulking, epiphyseal arrest, amputation, nerve stripping and anastomosis.

RESULTSSeven cases were followed up with mean periods 25.6 months. Functional evaluation according to a criterion formulated by author revealed a result of 2 excellent, 2 good and 3 fair.

CONCLUSIONSDigital gigantism of the foot is an uncommon congenital deformity of the foot characterized by overgrowth of both the soft-tissue and the osseous elements of the enlarged toe and forefoot. Surgical treatment is the unique method, and the goal is to reduce the size of the foot to allow fitting regular shoes and walking readily. There are several types of operations which to be chosen. The indication, the timing of operative intervention and the selection of operation type should be paid more attention.
