The methods to determine the total phenols, total saponins, and marker constituents salidroside, chlorogenic acid and 3, 4-dihydroxy-phenylethyl-β-D-glucopyranoside in the samples of Sargentodoxae Caulis were established to provide the evidence for the improvement and revision of the quality standard of the crude material recorded in the Chinese Pharmacopoeia (2015 Edition). The content of total phenols was determined by ultraviolet spectrophotometry, using gallic acid as a reference substance. The content of total saponins was determined by ultraviolet spectrophotometry, using 3-O-[β-D-xylopyranosyl-(1-2)-O-β-D-glucuronopyranosyl]-28-O-[β-D-glucopyranosyl] asiatic acid as a reference substance. The contents of salidroside, chlorogenic acid and 3,4-dihydroxy-phenylethyl-β-D-glucopyranoside were detected by HPLC. The linear ranges were 1.01-7.04 mg x L(-1) for total phenols, 37.7-201 μg for total saponins, 0.025 8-1.55 μg for salidroside, 0.076 2-5.44 μg for chlorogenic acid, and 0.064 9-3.47 μg for 3,4-dihydroxy-phenylethyl-βP-D-glucopyranoside, respectively. Their average recoveries were 99.12%, 99.11% 105.5%, 99.08%, and 101.6%, respectively. The contents of total phenols and total saponins were 3. 04% -11. 9% and 0. 87% -3. 63%. The contents of salidroside, chlorogenic acid and 3,4-dihydroxy-phenylethyl-β-D-glucopyranoside fluctuated from 0.018% to 0. 572%, from 0.041% to 1.75% and from 0.035% to 1.32%. The established methods were reproducible, and they could be used for the quality control of Sargentodoxae Caulis. The present investigation suggested that total phenols, salidroside, and chlorogenic acid should be recorded in the quality standard of Sargentodoxae Caulis and their contents should not be less than 6.8% for total phenols, 0.040% for salidroside, and 0.21% for chlorogenic acid.

Objeetive To investigate the efficacy and safety of long -term intravenous itraconazole for the treatment of invasive fungal infection ( IFI) in patients with hematological malignancies.Methods Sixty -nine patients with above mentioned conditions and diagnosed as IFI was administered at a dose of 200 mg every 12 hours for 2 days and followed by 200 mg every 24 hours at least 14 days.Responses were determined on the basis of clinical and microbiological criteria.Results The total response rates related to itraconazole among the IFI patients were 87.0%(60/69).Adverse effects rates were 18.8%, and 70% adverse effects happened winthin the first 14 days after intravenous itraconazole adminis-tered.Conclusion Long -term intravenous intraconazole antifungal treatment is effective and safe for hematologic malignancies with IFIs.

This study was aimed to investigate the expression and activity of membrane surface tissue factor (TF) of monocytes and platelets in peripheral blood cells from patients with cerebral infarction and their clinical significance. The TF expressions in monocytes and platelets from 25 patients with cerebral infarction were detected by flow cytometry, the TF activity was detected by chromogenic reaction method, and compared with 24 normal people used as control. The results showed that the TF expressions of monocytes and platelets in peripheral blood cells from patients with cerebral infarction were significantly higher than that in normal controls (p<0.01), and TF activity was also higher in patients than that in controls (p<0.01). In conclusion, the expression and activity of membrane surface in patients with cerebral infarction were enhanced, the hematocyte-derived tissue factor as a trigger in coagulation pathway is involved in pathological thrombosis in patients with cerebral infarction.

OBJECTIVETo investigate and clarify whether the genetic susceptibility to women with hypertensive disorder complicating pregnancy or pre-eclampsia is associated with polymorphisms and couple sharing rate of transporter associate with antigen processing genes(TAP).

METHODSOne hundred and two severe pre-eclampsia women and their spouses served as study group, and 200 normal pregnant women and their spouses were selected as control group. All pregnant women were primipara with single fetus. Genomic DNA was extracted from 2 mL cubital venous blood. We used the amplification refractory mutation system polymerase chain reaction(ARMS-PCR) to characterize TAP gene locus 333, 637, 379, 565, 665.

RESULTSWe observed eleven TAP haplotypes. There were four kinds of haplotypes(1A-1D) existing in TAP1, and seven kinds of haplotypes(2A-2G) existing in TAP2. The gene frequencies of TAP2B(Chi2=9.19, P<0.01, RR=4.18) and TAP2F(Chi2=5.34, P<0.05, RR=4.63) of patient group with pre-eclampsia were significantly higher as compared with control group. The analyses of some TAP haplotypes such as TAP1B(Chi2=4.87, P<0.05, RR=3.14), TAP1C(Chi2=5.42, P<0.05, RR=4.90), TAP2B(Chi2=9.65, P<0.01, RR=5.39) showed that the couple sharing rate of pre-eclampsia women and their spouses had statistically a highly significant increase in comparison with that of controls.

CONCLUSIONOur data suggest that the presence of TAP2B or TAP2F haplotypes should be considered as a risk increased to pregnant women being susceptible to hypertensive disorder complicating pregnancy; and also the elevated couple sharing rates of TAP1B, TAP1C and TAP2B genes will increase the opportunity or possibility of pregnant women suffering from pre-eclampsia disease.

Suvivin is a novel member of the inhibitor of apoptosis protein (IAP) family, which is known to be over-expressed in various carcinomas and associated with their biologically aggressive characteristics. The aim of this study was to investigate survivin expression in human medullary thyroid carcinoma (MTC) and a MTC cell line TT, correlate suvivin expression with clinicopathologic features of MTC, and test effects of antisurvivin oligonucleotides (ASODNs) on growth and apoptosis of TT cells. Survivin expression was immunohistochemically determined in formalin-fixed and paraffin-embedded specimens obtained from 10 cases of normal thyroid (NT) and 10 cases of MTC, and in TT cells. In TT cells, we confirmed survivin expression and its down-regulation by ASODNs using RT-PCR and Western blot analyses, and investigated effects of ASODNs on viability and growth by MTT assay and apoptosis by apoptotic analyses including DNA laddering assay, acridine orange/ethidium bromide staining and flow cytometric cell cycle analysis. Immunohistochemical analysis showed high survivin expression in MTC and TT cells, whereas no immunoreactivity was detectable in NT. Statistical analyses revealed no significant correlation of survivin expression with the clinicopathologic features of MTC. In TT cells, survivin expression at both mRNA and protein levels was confirmed and could be down-regulated by ASODNs concomitant with decrease in viability and growth, and increase in apoptosis. Our results suggest that survivin plays an important role in MTC independent of the conventional clinicopathologic factors, and ASODNs is a promising survivin-targeted gene therapy for MTC.
