To investigate formation mechanism of secologanic acid sulfonates in sulfur-fumigated buds of Lonicera japonica, secologanic acid was enriched and purified from the sun-dried buds of L. japonica by various column chromatography on macroporus resin HPD-100, silica gel and ODS. The stimulation experiments of sulfur-fumigation process were carried out using secologanic acid reacted with SO2 in the aqueous solution. The reaction mechanism could be involved in the esterification or addition reaction. The present investigation provides substantial evidences for interpreting formation pathway of secologanic acid sulfonates in sulfur-fumigated buds of L. japonica.

Twelve cases of Bartter's syndrome were reported and reviewed retrospectively.Usually vomiting was the first sympton in children,while fatigue was common in adults.Bartter's syndrome was characteristic of hypokalemia,metabolic alkalosis,elevations of plasma renin activity,serum angiotersinⅡand aldosterone and juxtaglomerular apperatus hyperplasia.Supplementation of potassium choloride was the main manner of therapy.

To investigate the mechanism of agarwood formation in Aquilaria sinensis induced by Lasiodiplodia theobromae, the fermentation liquor of L. theobromae was analyzed qualitatively and quantitatively by gas chromatography-mass spectrometry (GC-MS). JAs were detected in the fermentation liquor. The effect of the fermentation liquor on the abundance of sesquiterpenes in the callus of A. sinensis was analyzed by solid phase microextraction-gas chromatography-mass spectrometry (SPME-GC-MS). And the fermentation liquor stimulated alpha-guaiene, alpha-humulene and delta-guaiene biosynthesis in calli. It was inferred that L. theobromae produced JAs, which resulted in a significant increase of sesquiterpenes in A. sinensis.

In order to look for lower toxic and strongly active compounds, the structure of sesquiterpene lactones from Elephantopus scaber was modified. Deoxyelephantopin and scabertopin were isolated from the whole plant of Elephantopus scaber and hydrogenated and epoxidated. Five sesquiterpenoide derivatives were prepared and their structures were identified by IR, NMR and MS spectra analysis. Four sesquiterpenoides are new compounds. Part of the compounds show definite antitumor activity.

Fourteen compounds were isolated by column chromatography from the ethyl acetate extract of the seeds of Brassica campestris. Their structures were elucidated by physicochemical properties and spectroscopic data analysis. The isolated compounds were respectively identified as (5Z,7E)-4, 4-dimethyl-5-acetyl-5, 7-nonadienoic acid (1), indole-3-carboxaldehyde (2), blumenol A (3), vinylsyringol (4), sinapinic acid (5), sinapic acid ethyl ester (6), protocatechuic acid (7), crinosterol (8), campesterol (9), 7-oxo-stigmasterol (10), kaempferol (11), 2,5-dihydroxybenzoic acid (12), syringic acid (13) and daucosterol (14). Compound 1 was a new compound and the other compounds were isolated from this plant for the first time except for compounds 4, 5 and 13.

Objective To investigate the correlation of pretreatment serum squamous cell carcinoma antigen(SCCAg)with the clinico-pathological features of squamous cell carcinoma of uterine cervix and its significance as a prognostic factor.Methods One hundred and fourteen patients of squamous cell carcinoma of the uterine cervix(Ⅰbl-Ⅱa),who underwent pretreatment serum SCCAg evaluation and long-term follow-up after treatment were selected for this study.Clinical data were used to investigate the correlation between SCCAg and clinico-pathological features and factors that influence prognosis through univariate and multivariate analysis.Results Univariate analysis showed elevation of SCCAg(using≤1.5 mg/L as the cut-off value)was correlated with tumor size,deep stromal invasion and pelvic node metastasis (P0.05).However,between no pelvic node metastasis+elevated SCCAg cases and no pelvic node metastasis+normal SCCAg cases,there was a significant difference in DFS (71.8% vs 98.0%,P=0.003),recurrence rate(33.3% vs 9.8%,P=0.006)and local recurrence (26.5% vs 2.1%,P=0.001).Conelusions The independent prognostic factors for Ⅰ bl-Ⅱa squamous cell carcinoma of uterine cervix include elevated pretreatment SCCAg and pelvic node metastasis. Patients with elevated pretreatment serum SCCAg and no metastasis to pelvic lymph node(s)are at significantly elevated risk of local recurrence,and therefore need individualized treatment to improve local control and long-term survival.

Although previous reports showed drug-eluting stent (DES) could effectively inhibit neointima formation, in-stent restenosis (ISR) remains an important obstacle. The purpose of this study was to investigate different effects of paclitaxel on proliferation and cell cycle regulators between vascular smooth muscle cells (VSMCs) and vascular endothelial cells (VECs) of rats in vitro. The cultured VSMCs and VECs of rats from the same tissues were examined by using immunohistochemistry, flow cytometry and Western blotting in control and paclitaxel-treated groups. The results showed paclitaxel could effectively inhibit proliferation of VSMCs and VECs. However, as compared with VECs, proliferation of VSMCs in paclitaxel-treated group decreased less rapidly. The percentage of cells in G0-G1 and G2-M phases was reduced, and that in S phase increased after treatment for 72 h. The expression of cyclin D1 and B1, p27 and PCNA in VSMCs of paclitaxel-treated group was up-regulated, but that of p21 down-regulated as compared with VECs. It is concluded that there are significant differences in the expression of cell cycle regulators and proliferation rate between paclitaxel-treated VSMCs and paclitaxel-treated VECs, suggesting that the G1-S checkpoint regulated by paclitaxel may play a critical role in the development of complications of DES, which provides new strategies for treatments of ISR.

?AlM: To analyze and study the changes of intraocular pressure ( lOP) , visual field and P-ERG on patients with big cup/disk (C/D) in 24h.
?METHODS: A total of 120 cases ( 240 eyes ) diagnosed with big C/D (C/D>0. 3) were divided into group A (C/D<0. 6, 67 cases, 114 eyes ) and group B ( C/D≥0. 6, 73 cases, 126 eyes). Forty cases (80 eyes) with small C/D (C/D≤0. 3) were chosen as control group. All cases underwent 24h lOP examination, vision examination of 30-2 SlTA - standard static threshold and pattern electroretinogram ( P-ERG) examination. The differences between the examination indexes of the three groups were analyzed.
?RESULTS:There was no significant statistical difference in the 24h average lOP (P>0. 05) among the three groups, while the amplitudes had significant statistical differences (P<0. 05). Compared with the control group, the lOP amplitudes of group B were obviously higher, and the difference was of statistical significance (P<0. 05). ln terms of static threshold visual fields, the mean deviations (MD) and pattern standard deviations (PSD) of the three groups had significant statistical differences ( P < 0. 05 ). Comparison between every two groups:compared with the control group, the MD and the PSD were significantly increased in group B, and the difference was of statistical significance (P<0. 05); while there was no significant statistical difference in group A (P>0. 05);Compared with group A, the MD and the PSD were significantly higher in group B, and the difference was of statistical significance (P<0. 05). ln terms of P-ERG examination, there was no significant statistical difference in P50’s latent periods among the three groups (P>0. 05), but there were significant statistical differences in amplitudes (P<0. 05). Comparison between every two groups: compared with the control group, the P50’s amplitude was significantly decreased in group B, and the difference was of statistical significance (P<0. 05), while there was no significant statistical difference in group A (P>0. 05); Compared with group A, the P50’s amplitude of group B was significantly lower, and the difference was of statistical significance (P<0. 05).
?CONCLUSlON: When the patients’ C/D is no less than 0. 6, there are obvious changes of 24h lOP, static threshold visual field and P-ERG’s P50 wave. For patients with big C/D, a single lOP examination is far from sufficient, so an in-depth visual function examination should be performed. Meanwhile, it’s feasible to regard C/D 0. 6 as a screening criterion for suspected glaucoma.
