This study was aimed to establish X-ray diffraction (XRD) Fourier fingerprint of mineral Chinese medicine Actinolitum, in order to provide a new method for evaluating the quality of Actinolitum. Actinolitum samples were analyzed by the technology of powder XRD. And the XRD Fourier fingerprint was determined. Accord to the fingerprints and the intensity of each characteristic peak in XRD patterns of Actinolitum, the similarity of different samples were calculated using the law of cosines and the correlation coefficient method. Systematic cluster analysis was also used for the data. The results showed that XRD patterns of 10 certified products, 3 doping products and 2 counterfeits of Actinolitum were obtained. The geometric and topological characteristics of 10 certified products were consistent. XRD fingerprint of Actinolitum from 10 certified products had 18 common characteristic peaks. The similarity analysis showed that the similarity of XRD patterns common peak of certified products were higher among 15 samples (> 0.98). The similarity of doping products was slightly lower (0.85-0.97). And the counterfeits had the lowest similarity (< 0.2). These three had significant differences which can be distinguished. The results of cluster analysis were consistent with the similarity analysis results. It was concluded that XRD fingerprint had good specificity and feasible. It was accurate and reliable, which can be used to distinguish and evaluate Actinolitum.

Synthetic biology of traditional Chinese medicine (TCM) is a new and developing subject based on the research of secondary metabolite biosynthesis for nature products. The early development of synthetic biology focused on the screening and modification of parts or devices, and establishment of standardized device libraries. Panax notoginseng (Burk.) F.H.Chen is one of the most famous medicinal plants in Panax species. Triterpene saponins have important pharmacological activities in P. notoginseng. Squalene epoxidase (SE) has been considered as a key rate-limiting enzyme in biosynthetic pathways of triterpene saponins and phytosterols. SE acts as one of necessary devices for biosynthesis of triterpene saponins and phytosterols in vitro via synthetic biology approach. Here we cloned two genes encoding squalene epoxidase (PnSE1 and PnSE2) and analyzed the predict amino acid sequences by bioinformatic analysis. Further, we detected the gene expression profiling in different organs and the expression level of SEs in leaves elicited by methyl jasmonate (MeJA) treatment in 4-year-old P notoginseng using real-time quantitative PCR (real-time PCR). The study will provide a foundation for discovery and modification of devices in previous research by TCM synthetic biology. PnSE1 and PnSE2 encoded predicted proteins of 537 and 545 amino acids, respectively. Two amino acid sequences predicted from PnSEs shared strong similarity (79%), but were highly divergent in N-terminal regions (the first 70 amino acids). The genes expression profiling detected by real-time PCR, PnSE1 mRNA abundantly accumulated in all organs, especially in flower. PnSE2 was only weakly expressed and preferentially in flower. MeJA treatment enhanced the accumulation of PnSEI mRNA expression level in leaves, while there is no obvious enhancement of PnSE2 in same condition. Results indicated that the gene expressions of PnSE1 and PnSE2 were differently transcribed in four organs, and two PnSEs differently responded to MeJA stimuli. It was strongly suggested that PnSEs play different roles in secondary metabolite biosynthesis in P. notoginseng. PnSE1 might be involved in triterpenoid biosynthesis and PnSE2 might be involved in phytosterol biosynthesis.

Objective To investigate the photodynamic antitumor activity and chemical characteristics of pheophorbide A (PPBa)in vitro. Methods Breast cancer cells (MCF-7), lung cancer cells (A549), cervical cancer cells (HeLa), and three kinds of hepatoma cells (HepG2, hep3B and sk-Hep1) were planted in 96-well plates.The effects of light and dark toxicity, light intensity, and drug concentration on the phototoxicity of PPBa were investigated by MTT, and the uptake of PPBa was observed by Hoechst staining under a confocal microscope.The production of singlet oxygen was observed by flow cytometry and confocal microscopy with the reactive oxygen species detection kit.The photobleaching of PPBa was investigated by measuring the absorbance by a microplate reader according to the luminescence characteristics of PPBa. Results PPBa showed strong phototoxicity and low dark toxicity to six kinds of cancer cells, and IC₅₀ values to cancer cells were as follows: MCF-7:1.033 μmol/L, A549:1.911 μmol/L, HeLa: 2.319 μmol/L, HepG2:2.015 μmol/L, Hep3B: 2.089 μmol/L, sk-Hep1:2.467 μmol/L.The main uptake site of PPBa was the cytoplasm.The production of singlet oxygen was strongly dependent on the administration concentration, and photobleaching was very low. Conclusion For the six kinds of cancer cells, PPBa has the highest phototoxicity to breast cancer cells (MCF-7), with excellent properties and ideal photosensitizer characteristics.

Objective To analyze the clinical value of iron protein succinylate combined with erythropoietin (EPO) on the prevention and treatment of anemia in high-risk premature infants.Methods The clinical data of 100 high-risk premature infants with anemia treated in our hospital were analyzed retrospectively,and were divided into combined group (iron protein succinylate combined with EPO,n =58) and control group (EPO,n =42) according to different medication methods.Changes of serum iron,serum ferritin (SF),hemoglobin (Hb),red blood cell count (RBC) and hematocrit (HCT) before and after treatment were compared between the two groups.The rate and times of blood transfusion in the two groups were statistically analyzed.The incidence rates of adverse reactions and anemia were compared between the two groups.Results After treatment,the serum iron,SF,Hb,RBC,HCT and body weight in the combined group,Hb,RBC,HCT and weight in the control group were increased (P ＜ 0.05),but the serum iron,SF,Hb,RBC,HCT and weight in the combined group were higher than those in the control group (P ＜ 0.05).The rate and times of blood transfusion and the incidence rates of anemia at different times in the combined group were lower than those in the control group (P ＜ 0.05).There was no significant difference in the incidence of adverse reactions between the two groups (P ＞ 0.05).Conclusion Iron protein succinylate combined with EPO can effectively prevent anemia in high-risk premature infants,reduce the rate of blood transfusion and improve their hematopoietic function.

Objective To investigate the correlation between the level of presenilin-associated rhomboidlike protein (PARL) and the sperm motility,survival rate and deformity rate of sperm in workers exposed to aluminum.Methods A total of 162 male workers exposed to aluminum in a large aluminum enterprise in Guangxi were selected as the exposure group,and the 162 staff members of the service company were selected as the control group by matching the age and length of service.The concentration of aluminum in the working environment and the aluminum content in the blood and urine were determined by graphite furnace atomic absorption spectrometry and high performance liquid chromatography.Enzyme linked immunosorbent assay was used to measure the level of PARL protein in sperm and sperm function was evaluated.Results The average concentrations of aluminum in the batching,electrolysis and casting of aluminum exposure group were (6.72± 1.45),(7.23± 1.50) and (7.35± 1.72)mg/m3,which were significantly higher than those of the control group (F=8.314,P＜0.001).The content of aluminum in blood and urine of exposed group were significantly higher than those of control group (P＜0.05),while the levels of PARL of exposed group were significantly lower than those of control group (P＜0.05).Moreover,the sperm survival rate and sperm motility of exposed group were significantly lower than those of the control group,and the sperm deformity rates of exposed group were significantly higher than those of the control group(P＜0.05).Pearson correlation analysis showed that there was a positive correlation of sperm motility,sperm survival rate and protein level of PARL (rsprm motility=0.713,P=0.012;rsperm survival rate =0.628,P=0.008);while the sperm deformity rate and protein level of PARL showed a significant negative correlation (rsperm deformity rate =0.953,P =0.002).Conclusion The sperm function was significantly impaired in aluminum exposed workers,and the changes of sperm motility,survival rate and malformation rate were closely related to the protein level of PARL.
