ABSTRACT
OBJECTIVE To evaluate the quality of Indigo Naturalis， and to provide reference for the quality control of Indigo Naturalis. METHODS UPLC-MS/MS method was used to determine the contents of 6 indole alkaloids （indigo， indirubin， isatin， tryptanthrin， indole and indole-3-carboxaldehyde） in Indigo Naturalis from different origins. Cluster analysis， principal component analysis and partial least squares-discriminant analysis （PLS-DA） were used to evaluate the quality of Indigo Naturalis from different origins. RESULTS The contents of indigo， indirubin， isatin， tryptanthrin， indole and indole-3-carboxaldehyde in Indigo Naturalis from different origins were 20 320.83-26 585.01， 1 327.69-3 102.25， 141.69-894.50， 2.17-5.27， 2.14-5.93 and 1.69-4.34 μg/g， respectively. The Indigo Naturalis from different areas were clustered into two categories by cluster analysis. Samples S1， S2， S4， S6， S7， S9 and S10 were clustered into category Ⅰ， and samples S3， S5， S8， S11 and S12 were clustered into category Ⅱ. Indigo Naturalis from different origins was evaluated with 3 principal components. The results showed that category Ⅰ sample scored higher and had better quality， while category Ⅱ sample scored lower and had worse quality. PLS-DA showed that indigo， indirubin， tryptanthrin and isatin were the main substances that reflected the quality difference of Indigo Naturalis. CONCLUSIONS The quality of Indigo Naturalis from different origins is different， and the quality of Indigo Naturalis of different batches from the same area is not stable. The quality evaluation method of Indigo Naturalis established in this paper is stable and reliable， which can provide a basis for the quality control of Indigo Naturalis.
ABSTRACT
In this paper， through the collection and collation of ancient materia medica， medical books and medical formulary， combining with modern literature， the historical changes of the name， origin， position， harvesting time， medicinal parts， toxicity， functions and indications， processing methods of Rhododendri Mollis Flos （RMF） were systematically combed and verified， so as to provide reference for clinical application， processing standard and basic research of RMF. According to textual research， RMF is the dried flower of Rhododendron molle. In each historical period， there are many aliases and local names， being with phenomenon of homonyms and synonyms. RMF is mostly wild and planted in a small amount， harvesting time is mostly in March to April. However， the harvesting flowering period is differently described as initial bloom， full bloom and extensive bloom. RMF was first recorded in Shennong Bencaojing (《神农本草经》)， but it did not mention its medicinal parts. Then the flowers， fruits， roots are be used as medicine， but flowers are still the main medicinal parts. RMF had a long processing history， included fried， vinegar-fried， wine-fried， steamed， wine-steamed， vinegar-steamed， and many other processing methods in ancient times. However， at present， only raw products are used in clinical practice， and only a few modern books retain the methods of stir-fried and wine-steamed， believing that the processing can reduce toxicity of RMF.

Lung cancer is the leading cause of cancer death and the most common malignant tumor, the long-term survival of which has stagnated in the past several decades. Pileostegia tomentella Hand. Mazz is a traditional Chinese medicine called "Zhongliuteng" (ZLT) in the pharmacopeia, which has been proved to possess a potent anti-tumor effect on various cancers. In this study, the effects of ZLT N-butanol extraction (ZLTN) and ZLT ethyl acetate extraction (ZLTE) on the viability of non-small cell lung cancer cell (NSCLC) lines H1299 and A549 were evaluated. Here, we firstly reported that ZLTE significantly inhibited H1299 cells growth without affecting the release of lactate dehydrogenase (LDH). In addition, ZLTE induced caspase-dependent apoptosis in a concentration-dependent manner and increased the expression cleaved-PARP and decreased pro-caspase-3, pro-caspase-7, pro-caspase-8, and pro-caspase-9. Moreover, ZLTE increased the level of cellular reactive oxygen species (ROS) in H1299 cells to lead to apoptosis, which was reversed by N-acetyl-cysteine (NAC). Taken together, our results revealed that ZLTE induced caspase-dependent apoptosis via ROS generation, suggesting that ZLTE is a promising herbal medicine for the treatment of NSCLC.

ABSTRACT
Objective@#To evaluate the role of the serum testosterone level as an independent predictor of bone metastasis of prostate cancer.@*METHODS@#This study included 165 male patients with prostate cancer confirmed by biopsy. The patients were aged 58－78 (66.6±5.3) years and none had received androgen-deprivation therapy, chemotherapy or radiotherapy previously. We obtained the baseline clinical data from the patients, including prostate biopsy Gleason scores and the levels of serum prostate-specific antigen (PSA), total testosterone (TT), luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradiol (E2), alkaline phosphatase (ALP) and prolactin. According to the results of bone scanning, we divided the patients into a bone metastasis and a non-bone metastasis group and screened out the differential factors by univariate analysis and the independent predictor of bone metastasis using the multivariate non-conditional logistic regression model.@*RESULTS@#Univariate analysis showed no statistically significant differences between the bone metastasis and non-bone metastasis groups in age (P = 0.126) or the levels of serum LH (P = 0.930), FSH (P = 0.763) and E2 (P = 0.256), but that the former had remarkably higher Gleason scores (P < 0.01), total PSA (P <0.01) and ALP (P <0.01) but a lower TT level than the latter (P = 0.013). According to the results of multivariate logistic regression analysis, serum ALP (P <0.01, OR = 1.018 ［1.011－1.026］) and total PSA (P <0.01, OR = 1.029 ［1.015－1.044］) could be regarded as independent predictors of bone metastasis of prostate cancer but not low serum TT (P = 0.531, OR = 0.999 ［0.996－1.002］) or biopsy Gleason score (P = 0.898, OR = 0.787 ［0.412－1.9559］).@*CONCLUSIONS@#The low level of serum testosterone is closely associated with but not an independent predictor of bone metastasis of prostate cancer.
