ObjectiveTo analyze the quality changes of Platycladi Semen before and after the deterioration of moth-eaten and rancidity during storage. MethodFour types samples of Platycladi Semen， including normal， moth-eaten， oxidative rancidity and hydrolytic rancidity， were determined for volatile components， odor， and taste based on headspace solid phase microextraction/gas chromatography-mass spectrometry （HS-SPME/GC-MS） and electronic sensory techniques such as electronic nose and electronic tongue. Volatile components were identified by searching the database and manual comparison， the odor and taste were determined by the response values of the electronic nose and electronic tongue sensors， and the difference between samples before and after deterioration was studied by multivariate statistical analysis. ResultA total of 85 compounds were identified in Platycladi Semen samples. Compared with the normal samples， the number of volatile compounds in samples after hydrolytic rancidity decreased by 5， the number of volatile compounds in samples after moth-eaten and oxidative rancidity increased by 1 and 21， respectively. Aldehydes and acids accounted for majority of types. Among them， the contents of N-hexanoic acid， hexanal and propionic acid in the samples of oxidative rancidity reached 11.49%， 10.21% and 7.52%， which became the key indicators of rancidity. There was significant variance among the odor components corresponding to W1W， W2W and W1S sensors by electronic nose analysis. It was indicated that the value of sourness in deteriorated samples generally increased by mean of electronic tongue analysis. Compared with normal samples， the moth-eaten samples had changed slightly and rancidity samples had changed significantly especially oxidative rancidity samples of volatile components， odor and taste by multivariate statistical analysis. ConclusionIn terms of Platycladi Semen， the oxidative rancidity caused by nature storage for 12 months has the greatest impact on the quality. Therefore， it should be mainly to prevent oxidative rancidity to ensure the quality of Platycladi Semen.

Objective:To investigate the factors affecting the quality of post-harvest Angelicae Dahuricae Radix （Baizhi） and to provide the corresponding suggestions according to these factors. Method:A series of factors affecting the quality of Baizhi were analyzed comprehensively by visiting several origins， medicinal material markets， pharmacies， supermarkets and storehouses combined with plenty of literature reports. Result:The rot of Baizhi was the most common phenomenon after harvest， and mildew， discoloration and moth could occur during the processes of processing， storage and packaging. So the quality of Baizhi should be controlled strictly through the whole process. The roots of Baizhi should be harvested on sunny days to avoid mining damage and dried as soon as possible to prevent rotting. The drying methods included both traditional lime burial and modern ways such as sulfur fumigation， saline dehydration， sun drying method， and oven drying method. However， the water content should be strictly controlled. Furthermore， the storehouses should be disinfected firstly. The temperature and humidity of the storehouses should be controlled strictly. Some suitable ways could be adopted to prevent moth and discoloration during storage， which included airtight fumigation of aluminum phosphide， cold storage， air conditioning maintenance， antagonism storage with other Chinese medicinal materials， dry ice storage at room temperature， etc. Large quantities of Baizhi were generally packaged in woven bags. Otherwise， kraft paper bags， polyvinyl chloride plastic bags， glass bottles， aluminum foil composite film bags， and other packaging materials had been adopted for the retail. However， the packaging specification should be selected according to the situation. Conclusion:The quality of Baizhi can be directly affected by harvesting， drying， processing， storage and packaging. Scientific and reasonable methods should be adopted to ensure the quality of Baizhi.

The present study investigated the effects of chikusetsu saponin Ⅳa(CHS Ⅳa) on isoproterenol(ISO)-induced myocardial hypertrophy in rats and explored the underlying molecular mechanism. ISO was applied to establish a rat model of myocardial hypertrophy, and CHS Ⅳa(5 and 15 mg·kg~(-1)·d~(-1)) was used for intervention. The tail artery blood pressure was measured. Cardiac ultrasound examination was performed. The ratio of heart weight to body weight(HW/BW) was calculated. Morphological changes in the myocardial tissue were observed by HE staining. Collagen deposition in the myocardial tissue was observed by Masson staining. The mRNA expression of myocardial hypertrophy indicators(ANP and BNP), autophagy-related genes(Atg5, P62 and beclin1), and miR199 a-5 p was detected by qRT-PCR. Atg5 protein expression was detected by Western blot. The results showed that the model group exhibited increased tail artery blood pressure and HW/BW ratio, thickened left ventricular myocardium, enlarged myocardial cells, disordered myocardial fibers with widened interstitium, and a large amount of collagen aggregating around the extracellular matrix and blood vessels. ANP and BNP were largely expressed. Moreover, P62 expression was up-regulated, while beclin1 expression was down-regulated. After intervention by CHS Ⅳa at different doses, myocardial hypertrophy was ameliorated and autophagy activity in the myocardial tissue was enhanced. Meanwhile, miR199 a-5 p expression declined and Atg5 expression increased. As predicted by bioinformatics, Atg5 was a target gene of miR199 a-5 p. CHS Ⅳa was capable of preventing myocardial hypertrophy by regulating autophagy of myocardial cells through the miR-199 a-5 p/Atg5 signaling pathway.

Objective: To investigate the current harvest,processing,packaging and storage of Lilii Bulbus due to the great difference in quality of commercially available products,in order to realize the factors affecting the quality after harvest and provide reference for the standardized production. Method: A series of factors affecting Lilii Bulbus quality were analyzed comprehensively on the basis of both field survey in main producing areas and medicinal material markets and literature retrieval. Result: The current situation and problems in harvest,initial processing,drying technologies,packaging,and storage were summarized. Conclusion: The harvest link of Lilii Bulbus involves growing years,harvesting time,and collecting methods. The initial processing link involves stripping,cleaning,sulfur fumigation,and many cooking and drying methods. The hot-air,vacuum-freeze,far-infrared,and microwave methods are applied in drying Lilii Bulbus. The main metamorphic phenomena are brown staining,moth biting,and decay in the packaging and storage links. Lilii Bulbus are packed mainly in bulk,and a few of them are packed in plastic bags or vacuum bags for fresh bulbus. Because the operation process is not standard,the cooking and drying methods are the key factors affecting the quality of Lilli Bulbus. It is necessary to establish a scientific and unified standard operating procedure (SOP) for controlling the whole process of Lilii Bulbus in multiple links.

Objective:To explore the correlation between colors and contents of water and 5-hydroxymethylfurfural (5-HMF) in Ginseng Radix et Rhizoma Rubra (GRRR). Method:The colors were observed under sunlight on a sheet of white paper. The chroma value and color difference were determined and calculated by a colorimeter. Water content was determined by the oven-drying method. An HPLC method was established and used to determine the content of 5-HMF. The correlation was analyzed by the Spearman and Pearson analysis. Result:The colors of GRRR were yellowish-white,ocher-yellow,and yellowish-brown. The values of L*,a*,b*,and ΔE* had a certain range, and could reflect the colors of GRRR. The content of water ranged from 4.01%to 8.31%and was in accordance with the requirement the Chinese Pharmacopoeia. The content of 5-HMF ranged from below the limit of detection (1.985×10-4 μg) to 78.97 μg·g-1. The results of correlation analysis shows significant correlations between L*,a*,b*, ΔE* values and water content, that is to say,the deeper the color was, the higher the content of water was,but with no significant correlation with 5-HMF content. Conclusion:The color of processed GRRR was related to water content but not related to 5-HMF content,which was not consistent with the correlation between color and 5-HMF content that generally existed in a series of raw Chinese medicinal materials. It indicated an essential difference between the color shade of processed Chinese medicinal materials and the cause of color change of raw Chinese medicinal materials. Therefore,it was significant to control water content for ensuring the stability of GRRR. This study determined the colors of GRRR by a colorimeter, systematically determined 5-HMF content,and proposed the effect of water contents on the color of GRRR.

OBJECTIVE@#To observe the effects of electroacupuncture (EA) on reproductive outcomes in women with Shen (Kidndy) deficiency syndrome after in vitro fertilization-embryo transfer (IVF-ET), and explore the underlying molecular mechanism.@*METHODS@#Sixty-six infertile patients with Shen deficiency syndrome undergoing IVF-ET were divided into EA or control groups according to a random table, 33 cases in each group. Before undergoing IVF, patients in the EA and control groups received EA therapy and placebo needle puncture, respectively, for 3 menstrual cycles. Shen deficiency syndrome scores were assessed. Other outcome measures included the number of retrieved oocytes and fertilization, high-quality embryo and clinical pregnancy rates. Follicular fluid was collected on the day of oocyte retrieval, and granulosa cell expression of phosphatidylinositide 3-kinases (PI3K), serine-threonine kinase (Akt) and forkhead box O3 (Foxo3a) mRNA were measured by reverse transcribed and quantitative real-time polymerase chain reaction.@*RESULTS@#Syndrome scores for pre- versus post-treatments decreased significantly (16.53±1.75 to 8.67±1.61) in the EA group (P<0.05), but showed no significant change in the control group (17.18±1.58 to 14.74±1.58). A significant difference in score change was found between the EA and control groups (P<0.05). High-quality embryo and clinical pregnancy rates were both increased in the EA group compared with the control group [69.15% (195/282) vs. 60.27% (176/292) and 66.67% (22/33) vs. 42.42% (14/33), respectively, P<0.05]. The fertilization rate was equivalent in EA and control groups. No difference was found in the number of retrieved oocytes between the two groups. Granulosa cell expression levels of PI3K and Akt mRNA were significantly increased in the EA group compared with the control group, while the expression of Foxo3a was reduced (all P<0.05).@*CONCLUSIONS@#For infertile patients with Shen deficiency syndrome undergoing IVF, EA for tonifying Shen as an adjunct treatment may alleviate clinical symptoms and improve the high-quality embryo rate. The EA-induced mechanism may involve regulation of PI3K/Akt/Foxo3a expression in granulosa cells to improve the developmental microenvironment of oocytes and inhibit granulosa cell apoptosis, possibly contributing to the improved clinical pregnancy rate (Registration No. ChiCTR 1800016217).

OBJECTIVE: To study the monthly dynamics of physical and chemical indexes in Achyranthis Bidentatae Radix(ABR, the dried root of Achyranthes bidentata Bl.) stored in simple and cool warehouses. METHODS: ABR was stored in simple and cool warehouses for 27 months. The color was observed. The water content was determined based on the drying method. The contents of β-ecdysone and 5-hydroxymethylfurfural (5-HMF) were determined by HPLC method. The accumulation of temperature difference between the simple and cool warehouses was evaluated with a relative temperature cumulation (RTC) method. The monthly dynamics of physical and chemical indexes of ABR was analyzed with RTC. RESULTS: As the extension of storage time, the ABR stored in the simple warehouse showed deeper color and harder texture, but the ABR stored in the cool warehouse still had soft texture without significant color change. The contents of β-ecdysone in ABR stored in the two warehouses both gradually decreased and dropped to lower than the limit of 0.030% ruled by China Pharmacopoeia when being stored for up to 27 months. The contents of 5-HMF of ABR stored in the two warehouses both increased and were higher for the sample in the simple warehouse than that in the cool warehouse. CONCLUSION: The concept of RTC is put forward and used to study the monthly dynamics of chemical constituents in traditional Chinese medicine during storage for the first time. The physical and chemical indexes of ABR varies during storage. Two years of storage time of ABR is suggested.

To investigate the effect of icaritin (ICT) combined with GDF-5 on chondrogenic differentiation of bone marrow stromal cells (BMSCs), and discuss the action of Wnt signaling pathway, full bone marrow adherent method was used to isolate and culture SD rats BMSCs, and the cells at P3 generation were taken and divided into 6 groups： BMSCs group, ICT group, GDF-5 group, GDF-5+ICT group, GDF-5+ICT+SB216763 group, and GDF-5+ICT+ XAV-939 group. The cells were induced and cultured for 14 days. The morphology change was observed by inverted microscope. Alcian blue staining method was used to detect the changes of proteoglycans. RT-PCR was used to detect the mRNA expressions of aggrecan, Col2, Sox9, Dvl1, Gsk3β, and β-catenin. The protein expressions of collagen 2 (COL2) and β-catenin were detected by Western blot. The results indicated that, compared with the BMSCs group, gradual increase was present in proteoglycan Alcian blue staining; mRNA expressions of cartilage differentiation marker genes aggrecan, COL2, Sox9 and the protein expression of COL2, as well as mRNA and protein expressions of Wnt signaling pathway-related gene β-catenin, but with gradual decrease in Gsk3β mRNA expressions in GDF-5 group, GDF-5+ICT group and GDF-5+ICT+SB216763 group. On the contrary, compared with GDF-5+ICT group, there was a decrease in expressions of Dvl1, and β-catenin related to chondrogenic differentiation and Wnt signaling pathway, a increase in Gsk3β mRNA expression, and also a decrease in protein expressions of COL2 and β-catenin in GDF-5+ICT+XAV-939 group, with statistically significant difference between two groups. GDF-5 in combination with icaritin can induce chondrogenic differentiation of BMSCs in rats, and icaritin (ICT) can promote the chondrogenic differentiation. ICT can promote the chondrogenic differentiation of BMSCs in vitro probably by activating the Wnt/β-catenin signaling pathway.

Objective: To clone and characterize a late embryogenesis abundant protein SmLEA2 with its promoter region from Salvia miltiorrhiza, and to predict its probable function. Methods: SmLEA2 was cloned by PCR and RT-PCR from genomic DNA and cDNA. Protein structure and phylogenetic relationships were carried out by bioinformatic analysis. Gene expression in different organs and different development periods was detected by qPCR. Gene expression was also detected under different treatments. Results: By analyzing the cDNA library for S. miltiorrhiza with BLAST program, one of these sequences showed a high homology with late embryogenesis abundant (LEA) protein and was named as SmLEA2 (GenBank: HQ676610). We obtained 1 961 bp gene sequences of SmLEA2, which contained an intron and a single opening reading frame (ORF) of 960 bp encoding 319 amino acid peptides. Bioinformatic analysis showed that the putative SmLEA2 protein was a hydrophilic protein without signal peptides and transmembrane domains. The SmLEA2 protein was predicted with a molecular weight of 35 340 and a theoretical isoelectric point of 4.77. SmLEA2 was expressed in the roots, stems, and leaves of S. miltiorrhiza, and the most abundant in the stems. With the development of the flowers and seeds, its expression increased gradually. Expression of SmLEA2 could be induced by methyl jasmonate (MeJA) and abscisic acid (ABA). Conclusion: Thus, we speculate that SmLEA2 may be involved in seed development and plant defenses.

Drug susceptibility test (DST) was performed by the proportion method on the Lowenstein-Jensen (L-J) medium using isoniazid, rifampicin, ethambutol, and streptomycin. By Spoligotyping, 287 M. tuberculosis isolates were differentiated into 14 clusters. Then with 15-loci MLVA, these strains could be divided into 32 clusters, 228 genotypes. Of 15 VNTRs, 6 loci had the highly discriminatory powers, 6 loci presented moderate discrimination and 3 loci demonstrated less polymorphism. The DST results showed that 46 strains were resistant to at least one first-line anti-tuberculosis agent. There was a difference in the isoniazid resistance between Beijing and non-Beijing genotype strains. We concluded that the combination of Spoligotyping and 15 VNTR loci as the genotyping in our study was applicable for this region, the drug resistant isolates were identified, and the Beijing family was the most prevalent genotype in the rural counties of Xuzhou.

<p><b>OBJECTIVE</b>To observe the effects of Liuwei Dihuang Granule ([symbols; see text], LDG) for tonifying Kidney (Shen) on the outcomes of in vitro fertilization pre-embryo transfer (IVF-ET) of infertility women with Kidney-yin deficiency syndrome and to explore its mechanism by detecting the proteome expression in the follicular fluid.</p><p><b>METHODS</b>Sixty-six infertility patients of Kidney-yin deficiency syndrome who would undergo IVF-ET, were randomly assigned to a treatment group and a control group according to a random number table, 33 cases in each group. Another 33 cases of non-Kidney-yin deficiency syndrome was taken as a syndrome-control group. Besides Western routine therapy, LDG was given 3 menstrual cycles before IVF to the treatment group, and a placebo granule to the control and syndrome-control groups. The scores of Kidney-yin deficiency symptoms (sore waist and knees, dry vagina, dysphoria with feverish sensation in the chest, palms and soles, etc.) were assessed, the number of retrieved oocytes, rates of high quality oocytes and embryos, fertility rate and clinical pregnancy rate were recorded, and the follicular fluid was collected on the day when the ovum was picked up, the differential protein expression was detected using two-dimensional gel electrophoresis, and then, matrix assisted laser desorption ionization time-of flight mass spectrometry (MALDI-TOF-MS) was applied to identify the proteins.</p><p><b>RESULTS</b>The syndrome score in the treatment group decreased significantly from 16.09±2.58 to 8.67±2.13, while it changed insignificantly in the control group, with a significant difference in the lowering score between the two groups (P<0.05); the high quality rates of oocytes and embryos and clinical pregnancy rate were all superior in the treatment group to the control group (82.29% vs 78.08%, 76.76% vs 68.79%, 63.64% vs 36.36%, all P<0.05). The protein expression map from the follicular fluid showed that compared with the control group, 33 differential protein expressions were found in the syndrome-control group, among which 18 were down-regulated, and 15 up-regulated; in the treatment group 28 differential protein expressions were found, among which 15 were down-regulated, and 13 up-regulated. Through MALDI-TOF-MS, 14 proteins were identified (P<0.05).</p><p><b>CONCLUSIONS</b>For the infertility patients undergoing IVF, LDG could alleviate clinical symptoms, improve rates of high quality oocytes and embryos, so as to raise clinical pregnancy rate. The mechanism may be through regulating proteome expression in the follicular fluid to improve the developmental microenvironment for oocytes which would lead to a successful embryo implantation.</p>
