italic>Polygonatum franchetii Hua is a medicinal plant endemic to China from Polygonatum Mill. The chloroplast genomes of two P. franchetii individuals sampled from two different habitats were sequenced by using the DNBSEQ-T7 high-throughput sequencing platform. After assembly and annotation, the two complete chloroplast genomes were characterized, and then comparative and phylogenetic analyses were performed with other published chloroplast genome sequences from Polygonatum. The whole chloroplast genomes of the two P. franchetii individuals were 155 942 and 155 962 bp in length, with a large single copy region (LSC, 84 670 and 84 722 bp), a small single copy region (SSC, 18 564 and 18 566 bp) and a pair of reverse repeats (IRa/IRb, 26 354 and 26 337 bp), respectively. Both of them contained 113 genes, including 79 protein-coding genes (PCGs), 30 transfer RNA (tRNA) genes, and 4 ribosomal RNA (rRNA) genes. Comparative analyses showed that the genome length, the guanine and cytosine (GC) content, genes content and order were highly conserved between the two P. franchetii individuals and among different Polygonatum species. The detected repeat sequences, including dispersed repeats, tandem repeats and simple sequence repeats (SSRs), were also relatively similar in types and positions, though showing a slightly difference in number. No significant expansion or contraction of the inverted repeat regions was found. Sequences variation between the two P. franchetii individuals was lower than that among different Polygonatum species. Besides, coding sequences (CDS) showed less divergence than noncoding sequences, and sequence divergence of IRs regions was lower than that of the LSC and SSC regions, both intraspecifically and interspecifically. Eight sequences with high nucleotide diversity among different species were screened, all of which were found located in the LSC and SSC regions. Phylogenetic inference showed that all Polygonatum species clustered into a monophyletic clade with a 100% bootstrap value, within which, species in section Verticillata formed a distinct group, section Sibirica and section Polygonatum were sister groups. The two P. franchetii individuals grouped together and showed the closest phylogenetic affinity to P. stenophyllum Maxim., belonging to the section Verticillata. The chloroplast genome of P. franchetii and its phylogenetic position in Polygonatum were comprehensively investigated and clearly elucidated in this study, the results may lay a foundation for the resource development and utilization of P. franchetii, as well as further molecular identification and phylogenetic studies of medicinal Polygonatum species.

Its dried buds and leaves have good biological activities and have a long history of medicinal use in China and Europe. In this paper, we investigated the whole chloroplast genome characteristics, sequence duplication, structural variation and phylogeny of the Tussilago farfara L. After sequencing the Tussilago farfara L. chloroplast genome using Illumination technology, the complete Tussilago farfara L. chloroplast genome was further obtained by assembly and annotation, followed by a series of inverted repeat-large single copy/small single copy region contraction and expansion analysis, genome sequence variation, etc. The sequences of 13 homologous plants downloaded from NCBI were used to construct a neighbor-joining phylogenetic tree. The results showed that the total GC content of the chloroplast genome was 37.4% and the length was 150 300 bp; 125 genes were annotated, including 82 protein-coding genes, 35 tRNAs and 8 rRNAs; 148 (simple sequence repeats, SSR) loci were detected, and the relative synonymous codon usage showed that 31 codons out of 64 codons had a usage of >1. In the phylogenetic analysis, the chloroplast genomes of the seven species of Asteraceae, including the Yulin Tussilago farfara L., were highly conserved, and the sequence variation of the (large single-copy, LSC) and (small single-copy, SSC) regions was higher than that of the (inverted repeat, IR) region. This is in general agreement with the reported phylogeny of Yulin Tussilago farfara L. In this study, we obtained a high quality chloroplast genome and analyzed its genome characteristics, codon preference, SSR characteristics, SC/IR boundary, sequence variation and phylogeny, which can provide a basis for species identification, genetic diversity analysis and resource development of this medicinal plant.

Role of p 38 MAPK signaling pathway on post-stroke cognitive impairment and pharmacological research progress in the prevention and treatment with traditional Chinese medicine / 中国药房

Post-stroke cognitive impairment （PSCI） refers to a series of syndromes from mild cognitive impairment to dementia caused by stroke. The mitogen-activated protein kinases （MAPK）signaling pathway is a key pathway for transmitting cellular signals in mammals ，and p 38 is a classic branch of it. p 38 MAPK signaling pathway is involved in various pathophysiological processes such as cell growth ，differentiation，apoptosis and inflammatory response in central nervous system diseases. At present ，great progress has been made in clinical and basic experimental studies on prevention and treatment of PSCI by traditional Chinese medicine （TCM），but there is a lack of relevant systematic summary. Therefore ，this article summarizes the role of p 38 MAPK signaling pathway in PSCI and the pharmacological research progress of TCM in prevention and treatment of PSCI through p 38 MAPK signaling pathway.

[Ecological stoichiometric characteristics of soil and microbial biomass C, N, P in rhizosphere soil of Paris polyphylla and Panax japonicus cultivated understory].

Comparison of total organic carbon(TOC), total nitrogen(TN), total phosphorus(TP), soil microbial biomass carbon(MBC), nitrogen(MBN), phosphorus(MBP) and their stoichiometric ratios measuring from understory planting of Paris polyphylla and Panax japonicus rhizosphere soil with the data of the original forest soil will help us to understand the influence of different planting patterns between soil traits and soil microbial interaction and nutrient cycle characteristics. The results showed that the contents of TOC, TN and MBN were the highest in the rhizosphere soil of P. japonicus, while the highest values of TP, MBC and MBP were found in the rhizosphere soil of P. polyphylla. The changes of TOC∶TN, TOC∶TP, TN∶TP, MBC∶MBN, MBC∶MBP and MBN∶MBP of P. polyphylla and P. japonicus rhizosphere soil compared with the data of the original forest soil were 3.65 and 37.32%,-14.89 and 82.23%,-17.87 and 32.76%, 25.67 and-50.60%,-75.95 and-16.33% as well as-80.79 and 69.76%, respectively. TN and TP were significantly correlated with MBN and MBP respectively. Although, monoculture of P. polyphylla and P. japonicus changed soil nutrient level, it did not reach the state of nutrient deficiency. The demands for nitrogen and phosphorus between P. polyphylla and P. japonicus were quite different. According to their different habits, monoculture of P. polyphylla and P. japonicus could change the understory soil traits, resulting in allometric changes in part of soil nutrient stoichiometry and soil microbial stoichiometry, and then the disappearance of internal stability. The variations in the understory soil caused by P. polyphylla and P. japonicus is developing in completely different directions, whether this phenomenon indicates that the two species have less niche overlap needs further study.

Acupuncture improves locomotor activity and learning-memory ability by improving hippocampal cellular autophagy in rats with fetal intrauterine distress / 针刺研究

OBJECTIVE: To investigate the effect of acupuncture stimulation of head acupoints "Jin San Zhen" (JIN's Three Acupuncture Needles Therapy) on behavior reactions, hippocampal neuronal autophagy and expression of autophagy associated proteins (Beclin-1 and light chain 3 Ⅱ/Ⅰ [LC 3 Ⅱ/Ⅰ]) in rats with hypoxic-ischemic brain damage (HIBD) due to fetal intrauterine distress, so as to reveal its underlying mechanisms in improving neonatal HIBD. METHODS: Pregnant SD rats were used in the present study. The HIBD model was established by delayed caesarean delivery and bilateral uterine arteries clipping for 10 minutes. The HIBD rats were randomly divided into model group and acupuncture groups (n＝9 rats in each group). The other 9 rats delivered naturally were used as the normal control group. On day 14 after delivery, the neonatal rats in the acupuncture group received acupuncture stimulation of head acupoints ("Nao San Zhen""Nie San Zhen" and "Zhi San Zhen") by twirling each needle leftward and rightward for 10 times, once a day for 14 d. The open field test and Morris water maze test were used to determine the locomotive activity and spatial learning-memory ability, respectively. The ultrastructure and autophagosomes in the hippocampal neurons were observed by transmission electron microscope. The contents and expression levels of Beclin-1 and LC3 Ⅱ/Ⅰ in the hippocampus tissues were detected by flow cytometry and Western blot, separately. RESULTS: Compared with the normal control group, the time to go out of the central region of open field test, and the escape latency and duration of first platform-quadrant-crossing of spatial exploration of Morris water maze tests were significantly increased (P<0.01，P<0.05，P<0.001), and the total distance and number of activities in the central region, and the target quadrant resistance time and number of platform-cros-sing remarkably decreased in the model group (P<0.01, P<0.05), suggesting a decline of both locomotor activity and learning-memory ability after modeling. The expression level (%) of Beclin-1 protein and ratio of LC3 Ⅱ/Ⅰ proteins were considerably increased in the model group (P<0.01). Following acupuncture interventions, the locomotor activity and spatial learning-memory ability were obviously increased (P<0.05，P<0.01，P<0.001), and the expression of Beclin-1 protein and ratio of LC3 Ⅱ/Ⅰ were further up-regulated relevant to the model group (P<0.001). Moreover, ultrastructural observation showed serrated change of nuclear membrane and widened perinuclear space, vacuolization in the mitochondria, dilation of endoplasmic reticulum and increase of autophagosomes in the hippocampal neurons in the model group. These situations were relatively milder in the acupuncture group. CONCLUSION: Acupuncture of head acupoints of "JIN San Zhen" may increase locomotor activity and learning-memory abi-lity in rats with HIBD due to fetal intrauterine anoxia, which is closely with its effect in promoting hippocampal neuronal autophagy via up-regulating the expression of Beclin-1 and LC3 Ⅱ/Ⅰ.

There were statistically significant post-treatment differences in gastrocnemius and hamstring muscle tensions between the treatment and control groups (P<0.05). There were statistically significant pre-/post-treatment differences in the foot dorsiflexion angle and popliteal fossa angle in the treatment group (P<0.05). There was a statistically significant pre-/post-treatment difference in the posterior femoral angle in the control group (P<0.05). There were statistically significant post-treatment differences in the foot dorsiflexion angle and popliteal fossa angle between the treatment and control groups (P<0.05). There were statistically significant pre-/post-treatment differences in the GMFM score and the ADL score in the two groups (P<0.05). There were statistically significant post-treatment differences in the GMFM score and the ADL score between the treatment and control groups (P<0.05). Conclusions Scalp acupuncture plus MOTOmed virtual scene training is an effective way to treat spastic cerebral palsy. It can improve gross motor function and the ADL score in the patients.

Compressed sensing with linear-in-wavenumber sampling in spectral-domain optical coherence tomography.

We propose a novel method called compressed sensing with linear-in-wavenumber sampling (k-linear CS) to retrieve an image for spectral-domain optical coherence tomography (SD-OCT). An array of points that is evenly spaced in wavenumber domain is sampled from an original interferogram by a preset k-linear mask. Then the compressed sensing based on l1 norm minimization is applied on these points to reconstruct an A-scan data. To get an OCT image, this method uses less than 20% of the total data as required in the typical process and gets rid of the spectral calibration with numerical interpolation in traditional CS-OCT. Therefore k-linear CS is favorable for high speed imaging. It is demonstrated that the k-linear CS has the same axial resolution performance with ~30 dB higher signal-to-noise ratio (SNR) as compared with the numerical interpolation. Imaging of bio-tissue by SD-OCT with k-linear CS is also demonstrated.

Analysis of iodine nutritional status of pregnant women and level of neonatal heel blood thyroid stimulating hormone in Zhoupu and Kangqiao districts of Pudong New Area of Shanghai / 中国地方病学杂志

ObjectiveTo investigate the iodine nutritional status of pregnant women,newborn heel blood thyroid stimulating hormone(TSH) level and their relationship with urinary iodine(UI) level during pregnancy in Zhoupu and Kangqiao districts of Pudong New Area of Shanghai.Methods A total of 993 urinary samples(the first,second and third trimesters of pregnancy were 200 people,respectively),breast feeding(193 people) and non-pregnant women (200 people) in Zhoupu and Kangqiao districts of Pudong New area were collected from Apr 2009 to Dec 2010.Two hundred copies of neonatal heel blood samples were collected.Median of UI was measured by arsenic-cerium catalysis.TSH in neonatal heel blood was analyzed 72 h after birth by time resolved fluoroisnmunoassay(TRFIA).ResultsMedian UI of all pregnant women was 161.35 μg/L,and that in third trimesters of pregnancy( 126.35 μg/L) was lower than that of the first,the second,the breast feeding and non-pregnant women (178.80,180.50,167.90,163.40 μg/L,all P＜ 0.05).The percentage of UI level less than 150 μg/L in the third trimester[57.5％(115/200) ] was higher than that of the first[39.0％(78/200) ],the second[39.5％(79/200) ],the breast feeding [ 16.6％ (32/193) ] and non-pregnant women [ 23.0％ (46/200) ],respectively (all P ＜ 0.05).The percentage of UI level higher than 300 μg/L in the first [9.0％(18/200)],the second[8.0％(16/200) ] and the third trimester [ 5.0％ ( 10/200 ) ] of pregnancy was lower than that of the breast feeding [ 20.2％ (39/193) ] and nonpregnant [20.5％(41/200) ] women,respectively(all P ＜ 0.05).The level of neonatal heel blood TSH was(2.92 ± 1.83)mU/L,the range was 0.01 - 9.76 mU/L,11.0％(22/200) of the neonates heel blood TSH level(5 mU/L)exceeded the ratio of World Health Organization (WHO) standard ( ＜ 3％ ) suitable for iodine nutrition.Conclusions The overall level of iodine nutrition among pregnant women in Zhoupu and Kangqiao districts of Pudong New Area of Shanghai is in the appropriate range,but the pregnant women in the third trimester is in mild iodine deficiencies,and the neonates in these districts may be prone to iodine deficiency.Monitoring of iodine nutrition of pregnant women should be strengthened and iodine supplementation should be done scientifically.
