Eight compounds from six Chrysanthemum morifolium cv. 'Hangju' were determined and multivariate statistics, including principle component analysis (PCA) and partial least squares discriminate analysis (PLS-DA) were used to investigate the potential damaging effect of sulfr-fumigating process. Meanwhile, S, Mn, Fe, Cu, Pb were also detected by using ICP-MS and ICP-OES. In this study, dramatic chemical changes were found that the contents of flavonoid aglycones remarkably increased while those of glycosides and hydroxycinnamoylquinic acids were significantly reduced. The PCA score plots showed six samples were clearly classified into the non-fumigated and sulfur-fumigated types. And according to VIP > 1, the most important chemical markers were luteolin, apigenin and luteolin-7-O-glucoside which indicated that the extracted three components might have a marked effect on the discrimination among different group samples. And then, it was found that the residue of sulfur of SHJ were significantly higher than NHJ (P < 0.05). The established approach was applied to rapidly discriminate sulfur-fumigated HJ with combining the quantitative chemical analysis and multivariate statistical analysis, and then the result will provide some evidence to evaluat the quality of HJ and control its processing.

Objective To summarize our experience of simple neuroendoscopic endonasal transsphenoidal surgery for pituitary adenoma and discuss its advantages. Methods Forty-two patients with pituitary adenoma diagnosed by CT or MRI detection (diameters of the tumor: <1cm in 11 patients, 1-2cm in 11, 2-3cm in 18, >3cm in 8) were treated by simple neuroendoscopic endonasal transsphenoidal surgery. During transsphenoidal approach, the nasal mucosa was not incised and the nasal septum and median nasal conchae were not dissected. Under neuroendoscopic assistance, the anterior wall of the sphenoidal sinus and sellae base was opened directly and adenoma resection was performed. Results All the patients were followed up for 1-12 months. By postoperative MRI detection, adenomas were resected completely in 38 patients, subtotally in 4 cases. Rapid improvement of vision was noted postoperatively. The increased hormonal level in 18 of 22 patients was decreased to normal postoperatively and another 4 cases improved clinically in serum hormone levels during follow-up. Postoperative transient CSF leakage occurred in 6 cases and transient diabetes insipidus in 23 cases. Conclusions The simple neuroendoscopic endonasal transsphenoidal surgery for pituitary adanoma is safe, time-saving and without severe complications, provides a satisfactory deep illumination and a panoramic operative field. The injury to the patient and postoperative complications are less. The clinical application of the neuroendoscopy for pituitary adenoma is worthy of recommending.

Carbon source plays an important role in the constitutive expression of foreign proteins in Pichia pastoris. In present study, glucose , glycerol , methanol and oil acid, was used respectively as the only carbon source to constitutively express hAS in Pichia pastoris GS115 (pGAP9K-AS)in shaking flask. The result shows that oleic acid is the best (163 mg/L) compared with glycerol (83mg/L), glucose (76 mg/L)and methanol (57 mg/L). Since oleic acid is insoluble in water, glycerol was used as the carbon source in the high-density cell culture of GS115 (pGAP9K-AS) in a 30 liter bioreactor and 169 mg/L of angiostatin was obtained after 48h of culture. The expressed angiostatin is immunologically active as shown by Western blotting. The recombinant hAS inhibits bFGF induced CAM angiogenesis and suppresses the growth of B16 melanoma in C57BL/6J mice. The tumor inhibition rate is 90% after 12 days of treatment. Statistics analysis revealed that the tumor volume difference of mice between the hAS group and PBS group is prominent (P < 0.01).

OBJECTIVETo study the immediate and long-term effects of disasters caused by floods on residents health status.

METHODSStratified sampling by ranks of flood disaster occurred in 1996 and 1998, flood disaster areas and control areas were carried out. A retrospective study was also carried out to study all diseases involved during 1996 - 1999.

RESULTSThe incident rates of acute infectious disease in flooding areas in 1996 and 1998 were both higher than those of non-flooding areas (863.181/100 000 and 736.591/100 000, respectively). But there was no different between the incident rate of the first years in flooding areas and that of non-flooding areas. The prevalence rates of 8 kinds of chronic diseases related to circulatory system, nervous system, digestive system, injury and poisonous diseases in flooding areas were also higher than that in the non-flooding areas. The highest incidence rates of most diseases were in the mountainous flooding areas, followed by areas collapsed by flooding, and the lowest were seen in soakedareas by floods. The incidence rates of intestinal infectious diseases and respiratory infectious diseases were lower in areas where prevention and control measures were weak.

CONCLUSIONFlood could lead to the increase of incidence rates both on acute infectious diseases and non-infectious diseases. Interventions on non-infectious diseases should also be enforced to stop the epidemics when preventing and controlling acute infectious disease.

OBJECTIVETo study the expenses of hospitalization among the population in the flood disaster areas of Dongting Lake in Hunan province in 1998.

METHODSDescriptive epidemiologic study were conducted to analyze hospitalization expenses of the residents of 55 villages in flood disaster areas in 1998; single factors analysis and logarithmic linear regression analysis were carried out to explore influencing factors about hospitalization expenses of the residents.

RESULTSThe hospitalization rate was 4.59% with an average hospitalization expenses of 667.42 Yuan in the flood disaster areas' residents of Dongting Lake in 1998. Compared with populations without suffering from flood, hospitalization rate and the average hospitalization expenses of flood disaster Areas' residents of Dongting Lake in 1998 were higher and had significant difference. The average hospitalization expenses in 1998 was affected by flood types, family income, gender, age, literacy, occupation, outcome after leaving the hospital and hospital ranks.

CONCLUSIONThese results implied that the flood disease aggravated inhabitants' burden of disease in Dongting Lake areas; the factors influencing the average hospitalization expenses were multiple, and synthetic measures should be taken in the prevention and control of flood disaster.

OBJECTIVE: To evaluate the effect of baicalin on subarachnoid hemorrhage (SAH) in rats and explore the potential mechanisms. METHODS: Sprague-Dawley rats underwent experimental SAH and received treatment with baicalin at 10 or 50 mg/kg after 2 and 12 h of SAH. Neurological scores, brain water content, Evans-blue extravasation, and levels of glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), myeloperoxidase (MPO), and malondialdehyde (MDA) were measured 24 h after SAH. Expression of nuclear factor erythroid-related factor 2 (Nrf2), NAD(P)H: quinone oxidoreductase 1 (NQO1), matrix metalloproteinase-9 (MMP-9), aquaporin 4 (AQP4), occludin, and zonulaoccludens-1 (ZO-1) were detected in the brain by Western blot. Heme oxygenase-1 (HO-1) was detected by quantitative polymerase chain reaction, and tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) were assessed by enzyme-linked immunosorbent assay. RESULTS: Baicalin attenuated EBI 24 h after SAH in rats (P<0.05). Baicalin elevated neurological scores, GSH-Px, SOD, and increased the expression of Nrf2, NQO1, HO-1, occludin, and ZO-1 in SAH rats (P<0.05 or P<0.01). Baicalin reduced MPO, MDA, and the expression of MMP-9, AQP4, TNF-α, and IL-1β (P<0.05 or P<0.01). CONCLUSION Baicalin reduced SAH-induced EBI, partially via activation of the Nrf2/HO-1 pathway and inhibition of MMP-9 and AQP4.

【Objective】 To investigate the cell death-inducing effect of methyl rosmarinate (MR) on human hepatoma Hep-3B and SK-Hep1 cells and their potential mechanisms. 【Methods】 The effects of MR on the viability of Hep-3B, SK-Hep1 and MIHA cells were determined by cell counting kit-8 (CCK-8) assay. The morphological changes of three kinds of cells treated with different concentrations of MR were observed by optical microscopy. EdU assay and flow cytometry were used to detect the proliferation and apoptosis of Hep-3B and SK-Hep1 cells. Transwell assay was used to study the effects of MR on the migration and invasion of Hep-3B and SK-Hep1 cells. Western blotting was used to evaluate the protein expression levels of apoptosis, EMT and Akt/mTOR signaling pathways. 【Results】 After treated with different concentrations of MR (0~200 μmol/L) for 48 h, Hep-3B and SK-Hep1 cells activities were significantly decreased in a concentration-dependent manner (P<0.01), while there was no significant effect on MIHA cell activity (P>0.05), and the IC50 of Hep-3B and SK-Hep1 cells were 102.5 and 99.3 μmol/L, respectively. MR treatment (0-150 μmol/L) significantly inhibited the proliferation of Hep-3B and SK-Hep1 cells (P<0.05), while cell detachment and shrinkage were observed by optical microscopy on the Hep-3B and SK-Hep1 cells, while the morphology of MIHA cells was not changed. Compared with the control group, MR (100, 150 μmol/L) induced apoptosis in Hep-3B and SK-Hep1 cells, the expression levels of the pro-apoptotic proteins Bax and cleaved PARP were significantly increased (P<0.05), while the expression level of the anti-apoptotic protein Bcl-2 was significantly decreased (P<0.05). MR (100, 150 μmol/L) also inhibited the migration and invasion of HCC cells, significantly increased the expression of E-cadherin and decreased the expression of N-cadherin and Vimentin compared with the control group (P<0.05). Finally, Western blotting results showed that the expressions of p-Akt and p-mTOR in Hep-3B and SK-Hep1 treated by MR were significantly reduced in a dose-dependent manner, suggesting that MR may play an anti-cancer role by inhibiting Akt/mTOR signaling pathway. 【Conclusion】 MR can promote apoptosis in Hep-3B and SK-Hep1 cells, which may be closely related to the inhibition of Akt/mTOR signaling pathway.
