ObjectiveThe purpose of this study was to assess the efficacy,safety and optimal dose of tacrolimus monotherapy in patients with refractory lupus nephritis(LN) who were resistant to cyclophosphamide(CYC).MethodsA total of 14 LN patients (2 men and 12 women) with persistent proteinuria who were resistant to CYC treatment more than 8 g for half a year were enrolled.Tacrolimus was initiated at 2 mg/d (patient weight＜60 kg) or 3 mg/d(patient weight≥60 kg) which was administered in two divided doses.Prospective data on daily proteinuria,serum album level and serologic lupus activity were collected and followed for 6 months.ANOVA and Pearson correlation analysis were used for statistical analysis.Results Mean age at baseline was(30±9) years.Mean urinary protein decreased significantly from(6.2±5.1) g at baseline to (1.1±0.9) g at 6 months (F=16.21,P＜0.01).Mean serum album level increased significantly from (27.9±9.7) g/L at baseline to(37.8±2.2) g/L at 6 months(F=16.71,P＜0.01 ).Complete or partial response was observed in 86％ of patients receiving tacrolimus therapy.The effective dosage in this study was 0.03-0.06mg·kg-1·d-1 of the patients who had complete response or partial response to tacrolimus.The tacrolimus level in partially and completely responding patients was less than 3 ng/ml.There was no significant difference among blood tacrolimus levels of complete,partial,and no response patients [(1.6-±0.4),(2.0±0.6) and (22±1.1) ng/nl],respectively).No definite correlation was found between efficacy and tacrolimus level.Tacrolimus was well tolerated at current dose,besides one with new onset hypertension and one with alopecia.ConclusionOur results suggest that tacrolimus at low dosage and serum level is potentially effective and safe for the treatment　of patients with LN and persistent proteinuria resistant to CYC.The optimal dosage of tacrolimus for LN may　be 0.03-0.06 mg·kg-1·d-1.

Sandalwood essential oil has been widely used not only as natural medicines but also in perfumery and food industries, with sesquiterpenoids as its major components including (Z)- α-santalol and (Z)-β-santalol and so on. The mature heartwoods of Santalum album, Santalum austrocaledonicum and Santalum spicatum are the major plant resources for extracting sandalwood essential oil, which have been overexploited. Synthetic biology approaches have been successfully applied to produce natural products on large scale. In this review, we summarize biosynthetic enzymes of santalenes and santalols, including various santalene synthases (STSs) and cytochrome P450 monooxygenases (CYPs), and then highlight the advances of biotechnological production of santalenes and santalols in heterologous hosts, especially metabolic engineering strategies for constructing santalene- and santalol-producing Saccharomyces cerevisiae.

OBJECTIVETo compare the contents of resveratrol and polydatin in some materials of Polygonum cuspidatum from various sources, so to screen and obtain the suitable cultures for the following metabolism regulation study.

METHODRP-HPLC method was applied to simultaneously assay resveratrol and polydatin in different samples.

RESULTBy the modified methods of extraction and determination, large amount of materials were screened. The results indicated that the contents of resveratrol and polydatin in root and rhizome were evidently higher than those in the leave and stems. The content of polydatin in the seedlings cultured indoor for three months was 1.27% and showed a 1.25-time increse than that in the wild plants, while the content of resveratrol (0.401%) approached that in the wild plants. Both of resveratrol and polydatin could be examined from different tissue cultures of P. cuspidatum, such as the sterile seedlings, callus, suspended cells and hairy roots, and the levels of them were closely related to the growth speed, physiological status and developmental phase. Hairy roots had the highest potentiality in several tested cultures and the increase rate of dry weight was 8.29 when cultured in vitro for 30 days, and showed a 8.4-fold and a 192.8-fold increase compared with those of natural roots and suspended cells, respectively. The content of polydatin in the hairy roots was up to 0.037% and that of resveratrol was 0.007%.

CONCLUSIONThe established analysis method is rapid, simple and accurate, especially adapted to the simultaneous determination of resveratrol and polydatin in massive biological samples. Hairy-root cultures have the superiority among the tested materials of P. cuspidatum and are suitable for the large-scale biomass and consistent production of efficient constituents.
