Orobanche caerulescens is an important medicinal resource in Orobanchaceae. The present study aims to establish methods for determination of acteoside, crenatoside, and total phenylethanoid glycosides in O. caerulescens, and determine the content in 15 samples to evaluate the resource utilization of this medicinal plant. The content of acteoside and crenatoside were quantitatively determined by HPLC, while total phenylpropanoid glycosides was estimated by UV-VIS spectrophotometry. According to the results, the content of acteoside was the highest in O. caerulescens, followed by crenatoside. The contents of acteoside, crenatoside, and total phenylethanoid glycosides were between 1.15% - 15.60%, 0.83% - 4.47%, and 6.78% - 27.43%, respectively, which had significant differences. The acquisition time has great influence on the content of main components of O. caerulescens. The content of phenylethanoid glycosides is higher in the samples which were collected at the flowering stage. The two determination methods were proved to be simple, accurate and reliable, and can be used to evaluate the quality and resource utilization of O. caerulescens.

Objective To build the cohort of drug resistance and analyze treatment efficiency of AIDS patients and situation of drug resistant mutations among HIV-1 infected individuals.Methods A cohort of 116 HIV-1 infected patients was built and their treatment progress were acquired once every 6 months.At the sanle time CD4+ T cell counts and HIV-1 viral load were measured and genotyping for drug resistance was determined by a home brew nested PCR.Results The CD4+ T cell count(470±251/ml)was higher than that before treatment in patients who were treated by AZT/DDI/NVP or D4T/DDL/NVP.The viral load was lower than that before treatmenL The drug resistant mutation frequency increased gradually along with treatment.The CD4+ T cell count was decreased and viral load was increased and the prevalence of drug resistant mutation was increased in the patients who changed regimens to AZT/3TC/NVP or D41/3TC/NVP.Only one primary mutation that was resistant to non-nucleoside reverse transcriptase inhibitors (NNRTIs)was detected in the naive patients.The cross-resistant mutation was detected in two patients after 6 months treatment. The intermediate resistance to lopinavir(LPV) was detected after 12 months treatment.The prevalence of high-grade resistances to NNRTIs was increased obviously,and the prevalence of multi-resistance and cross-resistance was detected in 5 patients after 36 months treatment.Conclusions The prevalence of primary mutation was rare in naive HIV-1 infected patients.The prevalence of drug resistant mutation was inereased gradually along with treatment.Ahhough few regimens were available,the treatment effect could last relatively long period of time if patients keep taking medicine stably.The regimens could be changed according to the results of drug resistant test.

AIM: To study the role of nitric oxide ( NO ) and γ-aminobutyric acid ( GABA) in the formation of amblyopia by establishing 2 different types of amblyopic models.METHODS:A total of 18 aged 3-week kittens were randomly divided into monocular deprivation, strabismus and normal groups. All types of amblyopia were developed in the experimental eyes that were detected by P-VEP 12wk later. The cats were killed and the immunocytochemistry staining method were applied to observe under the light microscope the changes of distribution and positive cells areas of NO and GABA across the amblyopic retinal, compared to that from the normal cats of identical age.
RESULTS: The P-VEP showed that the amplitude of wave P1 was lower (P<0. 05) and the P1 latent time was longer ( P<0. 05 ) in two types of amblyopic cats than those in the normal cats. Compared to the normal cats, the NO and GABA positive cells areas were obviously reduced ( P<0. 05 ) across the retina in the amblyopic cats. But no significant difference was found between two kinds of amblyopic cats.
CONCLUSION:The NO and GABA play an important role in the formation of amblyopia in the level of retinal.

A sesquiterpene synthase (AsSS4) full-length open reading frame (ORF) cDNA was cloned from wounded stems of Aquilaria sinensis by RT-PCR method. The result showed that the ORF of AsSS4 was 1,698 bp encoding 565 amino acids. Prokaryotic expression vector pET28a-AsSS4 was constructed and transformed into E. coli BL21 (DE3) pLysS. Recombinant AsSS4 protein was obtained after induction by IPTG and SDS-PAGE analysis with a MW of 64 kD. Enzymatic reactions using farnesyl pyrophosphate showed that recombinant AsSS4 protein purified by Ni-agarose gel yielded five sesquiterpene compounds, cyclohexane, 1-ethenyl-1-methyl-2, 4-bis(1-methylethenyl)-, β-elemene, α-guaiene, α-caryophyllene and δ-guaiene. This paper reported the first cloning and functional characterization of AsSS4 gene from A. sinensis, which will establish a foundation for future studies on the molecular mechanisms of wound-induce agarwood formation in A. sinensis
