ABSTRACT
Objective To investigate the current status of anti-mullerian hormone (AMH) in healthy women in the healthy childbearing age in Shenzhen area,and to explore its application value in polycystic ovary syndrome (PCOS) and prature ovarian syndrome (POF) treatment.Methods Collected 860 cases of medical health women of childbearing age in Shenzhen BaoanDistrict People's Hospital from January 2016 to March 2017 as control group,and at the same time selected 59 cases of patients with PCOS and 61 cases of patients with POF as observation group.Adopted DXI800 chemiluminescence analyzer to test serum AMH level of control group,patients with PCOS and POF group respectively before and 3 months after treatment,and the testing results were analyzed.Results The serum AMH level of Healthy women of childbearing age was 4.91 ±1.56 ng/ml,18～25 years old group was 5.38±1.27 ng/ml,31～35 and 36～42 years old group were 4.53±1.40 ng/ml and 3.95±1.16 ng/ml,being all lower than that in group 18～25 years old (t=3.082,5.066,all P＜0.05).While 26～30 years old group was 5.09± 1.45 ng/ml,and compared with 18～ 25,there was no statistically significant difference (t=0.892,P＞0.05).Before the treatment,the serum AMH level of PCOS was 10.13± 3.85 ng/ml,significantly higher than the control group,the difference was statistically significant (t=13.924,P＜0.01),while the serum AMH level of POF group and wait POF patients were 1.04±0.37 ng/ml and 2.39±0.87 ng/ml,significantly lower than the control group (t=10.913,8.042,all P＜0.05),and POF lower than wait POF group (t=2.875,P＜0.05).After treatment,the serum AMH level of PCOS was 5.22± 1.58 ng/ml,significantly lower than before treatment (t =11.106,P＜0.05),and there was no statistically significant difference between control group (t=1.036,P＞0.05),the serum AMH level of POF and wait POF were 4.49±1.32 ng/ml and 4.54± 1.47 ng/ml,significantly higher than the before treatment (t=9.608,7.253,all P＜0.05),and compared with the control group there were no statistically significant differences (t =1.209,0.918,all P＞0.05).Conclusion Before the treatment,the serum AMH levels of PCOS were increased significantly,and the serum AMH levels of POF and wait POF patients were significantly reduced,while the serum AMH levels of PCOS,POF and wait POF patients were all restored to normal levels after treatment.Therefore,AMH has certain application value in the diagnosis and treatment evaluation of women PCOS and POF disease.
ABSTRACT
Tropical forests vegetation and community research have tended to focus on the tree component, and limited attention has been paid to understory vegetation. Species diversity and composition of the understory of tropical seasonal rain forest were inventoried in a 625m² area (for sapling layer) and a 100m² area (for herb/seedling layer) in three 1ha plots. We found 3068 individuals belonging to 309 species, 192 genera and 89 families. The most important family as determined by the Family Importance Value (FIV) was Rubiaceae in both sapling and herb/seedling layers. In terms of Importance Value Index (IVI), the shrub Mycetia gracilis (Rubiaceae) was the most important species in the sapling layer and the pteridophyte Selaginella delicatula (Selaginellaceae) was the most ecological significant species in the herb/seedling layer. Much more vascular plant species were registered in the understory than in the tree layer totaled among the three plots. The species diversity did not differ significantly among the tree layer, sapling layer and herb/seedling layer. Given that we still know little about the understory plant community for growth forms other than trees, the results from the present study indicate that more attention should be paid to the understory vegetation during the decision-making process for biodiversity conservation in the tropical forests.

La investigación de la vegetación y las comunidades presentes en bosques tropicales han tendido a centrarse en el componente arbóreo, y se ha prestado poca atención a la vegetación del sotobosque. La diversidad de especies y la composición del sotobosque de los bosques tropicales estacionales fueron inventariados en un área de 625m² (identificación de árboles jóvenes) y un área de 100 m² (capa de plántulas/hierbas) en tres parcelas de 1 ha. Hemos encontrado 3 068 individuos pertenecientes a 309 especies, 192 géneros y 89 familias. La familia más importante según lo determinado por el Valor de Importancia por Familia (FIVFamily Important Value) fue Rubiaceae, tanto en la capa de árboles jóvenes como para la de plántulas y hierbas. En términos del Índice de Valor de Importancia (IVI-Importance Value Index), el arbusto Mycetia gracilis (Rubiaceae) fue la especie más importante en la capa de árboles jóvenes y la pteridofitas Selaginella delicatula (Selaginellaceae) fue la especie más importante ecológica en la capa de plántulas e hierbas. Mucho más especies de plantas vasculares fueron inventariadas en el sotobosque que en el estrato arbóreo de las tres parcelas juntas. La diversidad de especies no difirió significativamente entre la capa de árboles, la de árboles jóvenes y la de plántulas y de hierbas. Teniendo en cuenta que aún sabemos poco sobre la comunidad de plantas del sotobosque, los resultados del presente estudio indican que debe prestarse más atención a la vegetación del sotobosque durante el proceso de toma de decisiones para la conservación de la biodiversidad en los bosques tropicales.

The aim of this work was to describe the morphology of seedlings and saplings of Pachyrhizus ahipa, a cultivated species of Phaseoleae (Fabaceae), analysing the seedling type and characterizing the structure of cotyledons, eophylls and metaphylls. It was observed that the seedling was semi-hypogeal, a germination type not yet recorded for the Phaseoleae tribe. It formed two opposite and unifoliated eophylls with an evident pair of stipels. Metaphylls were trifoliolate and had alternate phyllotaxis. Both eophylls and metaphylls were pinnate, camptodromous, and brochidodromous.
É de conhecimento geral que existe grande escassez de estudos referentes às fases juvenis das plantas, importantes como subsídio para diversos trabalhos ecológicos, taxonômicos e filogenéticos. Com base nesse pressuposto, descreveram-se morfologicamente plântulas e plantas jovens de Pachyrhizus ahipa, espécie cultivada de Phaseoleae (Fabaceae), analisando-se o tipo de plântula e caracterizando estruturalmente os cotilédones, eofilos e metafilos. Verificou-se que a plântula é semi-hipógea, tipo de germinação até então não registrado para a tribo Phaseoleae. A plântula forma dois eofilos unifoliolados e opostos, acompanhados por evidente par de estipelas. Os metafilos são trifoliolados, de filotaxia alterna. Tanto eofilos quanto metafilos são pinados, camptódromos e broquidódromos.
ABSTRACT
The regeneration of the rain forest tree Peltogyne purpururea Pittier after selective logging was studied in Mogos, Osa Peninsula, Costa Rica. The distribution of all adult trees of P. purpurea according to diameter at breath height (dbh) categories revealed that the distribution of the adult trees followed a bell-shaped curve. The largest number of individuals was found in the 70 to 80 cm dbh category. We did not find any significant differences in the distribution of saplings around seed-producing trees. There were similar numbers of saplings in the four transects established around each reproductive tree following the four cardinal directions. Overall, the majority of the saplings were found in the first meters around each seed-producing tree. There was another peak in the number of saplings at the distance where the crown of the tree ended. Logging can negatively affect the regeneration of P. purpurea.
Se estudió la regeneración de una población del árbol Peltogyne purpurea Pittier después de una corta selectiva de madera en el bosque lluvioso tropical de Mogos, Península de Osa, Costa Rica. La distribución de los árboles adultos de P. purpurea según el diámetro del tallo a la altura del pecho tiene forma de campana. La categoría con la mayor cantidad de individuos correspondió a los árboles con tallos con diámetros entre 70 y 80 cm. No hubo diferencia significativa en el número de brinzales encontrados en los transectos establecidos siguiendo los cuatro puntos cardinales alrededor de los árboles reproductivos (madre). En general, la mayoría de los brinzales se encontraban en los primeros metros alrededor del árbol madre. Se observó otro pico de abundancia de brinzales a la distancia correspondiente con el final de la copa del árbol. La extracción de madera puede tener un efecto negativo en la regeneración de P. purpurea.
