ABSTRACT
Kadsura coccinea (Lem.) A.C.Sm. in the Schisandraceae family is woody vine plant, which produce edible red fruits that are rich in nutrients and antioxidant activities. Herein, we assembled the complete chloroplast genome of Kadsura coccinea by next-generation sequencing technologies. The complete chloroplast genome sequence of Kadsura coccinea is 145,413 base pairs (bp) in length, including a pair of inverted repeat regions (IRs, 16,431 bp), one large single-copy region (LSC, 94,511 bp), one small single-copy region (SSC, 18,040 bp). Besides, the complete chloroplast genome contains 126 genes in total, including 82 protein-coding genes, 35 tRNA genes, and 8 rRNA genes. Phylogenetic analysis showed that Kadsura coccinea has the closest relationship with Kadsura longipedunculata. Our study lay a foundation for further research of Kadsura coccinea.
ABSTRACT
OBJECTIVES@#To study the effect of levothyroxine sodium tablets on the growth and development and thyroid function in preterm infants with thyroid dysfunction.@*METHODS@#A retrospective analysis was performed for 82 preterm infants who were born in the Department of Obstetrics of the First People's Hospital of Yunnan Province, from January 1, 2013 to December 31, 2017, and these infants were hospitalized after birth in the Department of Neonatology of the hospital. They were regularly followed up to observe growth and development and thyroid function at the outpatient service of the Department of Neonatology. According to thyroid function test results, they were divided into an abnormal thyroid function group (observation group; @*RESULTS@#There were no significant differences in physical development indices (body length, body weight, and head circumference) between the observation and control groups at various gestational ages after follow-up to the corrected age of 12 months (@*CONCLUSIONS@#Early diagnosis and reasonable treatment can reduce the impact on growth and development in preterm infants with thyroid dysfunction. Most preterm infants tend to have transient thyroid dysfunction, while those with positive results of neonatal screening are more likely to develop permanent thyroid dysfunction.

Vatica guangxiensis S.L. Mo is an evergreen large tree of Dipterocarpaceae. Herein, we assembled the complete chloroplast genome of Vatica guangxiensis by next-generation sequencing technologies. The complete chloroplast genome sequence of Vatica guangxiensis is 151,010 base pairs (bp) in length, including a pair of inverted repeat regions (IRs, 23,827 bp), one large single-copy region (LSC, 83,353 bp), one small single-copy region (SSC, 20,003 bp). Besides, the complete chloroplast genome contains 123 genes in total, including 83 protein-coding genes, 36 tRNA genes, and 8 rRNA genes. Phylogenetic analysis showed that Vatica guangxiensis has the closest relationship with Vatica mangachapoi. Our study lay a foundation for further research of Vatica mangachapoi.
ABSTRACT
Paphiopedilum emersonii is an endemic terrestrial orchid in China. In this study, the chloroplast genome of P. emersonii was determined from BGISEQ-500 sequencing data. The total chloroplast genome was 162,590 bp in length, consisting of a large single-copy region (LSC, 87,852 bp), a small single-copy region (SSC, 870 bp), and two inverted repeat regions (IRA and IRB, 36,934 bp, each). The complete chloroplast genome contains 131 genes, including 81 protein-coding genes, 38 tRNA genes, and 8 rRNA genes. In addition, the phylogenetic analysis indicates that P. emersonii was sister to Paphiopedilum micranthum. The chloroplast genome will contribute to the research and conservation of P. emersonii.
ABSTRACT
OBJECTIVE: To explore the growth dynamic and photosynthetic characteristics of Ardisia corymbifera var. tuberifera in bionic wild cultivation. METHODS: The test of bionic wild cultivation was conducted with two-year-old seedlings as well as three-year-old cuttings of Ardisia corymbifera var. tuberifera, and their growth dynamic and photosynthetic characteristics were studied. RESULTS: Both seedlings and cuttings of Ardisia corymbifera var. tuberifera maintained good growth in imitation of the wild, the height were increased by 9.2 cm and 12 cm, base diameter were increased by 2.48 mm and 2.39 mm,and crown width were increased by 10.6 cm and 17 cm, respectively. Two-year-old seedlings branched only once a year, and three-year-old cuttings branched thrice a year. There were no significant differences in all photosynthetic parameters of the two kinds of seedlings, and the range of growth light intensity of Ardisia corymbifera var. tuberifera was wider. Owing to the weaker light quantum efficiency under lower light and relatively lower light photosynthetic capacity under higher light, its competition ability was lower in the field. CONCLUSION: The increases of height and crown width were greater in cuttings than those in seedlings, and the transplanting survival rate of the former was larger.

FTIR spectra from 16 kinds of Camellia Sect. Chrysantha by Fourier transform infrared spectroscopy (FTIR) method combined with the system clustering and correlation coefficient method were used to analyze and compare these spectral data. The results, show that: Camellia Sect. Chrysantha of 16 kinds were divided into three groups, the first kind was: C. longzhouensis etc, in all eleven kinds; The second kind was: C. achrysantha, C. limonia, C. pingguoensis and C. chuongtsoensis; The third kind was C. microcarpa, which for a class alone. According to the difference in related anatomy and morphology, this study supported that C. longgangensis and C. ptilosperma should be incorporated into one kind; C. multipetala, C. longgangensis, C. parvipetala, C. tunghinensis and C. limonia, C. achrysantha, C. microcarpa, C. nitidissima, C. terminali and C. pingguoensis should be divided into separate species. FTIR-cluster analysis can be used as a possible means for the identification of Camellia Sect. Chrysantha.
