ABSTRACT
ObjectiveTo study the effect of Siwutang （SWT） on intestinal flora in rats with diminished ovarian reserve （DOR） induced by Tripterygium wilfordii polyglycoside （TWP） based on 16S rRNA sequencing. MethodTwenty 8-week-old female SD rats were randomly assigned into four groups： blank group， model group， SWT high-dose group， and SWT low-dose group. Except the blank group， the other three groups were underwent intragastric administration of TWP tablets at a dose of 50 mg·kg-1 for 14 days. On day 15， the high-dose group was administrated at 3 times of the human dosage （40 g/person/day）， the low-dose group at 1.5 times of the human dosage， and the model group and the blank group with the same volume of normal saline for 18 days. Then， feces were collected for 16S rRNA sequencing. One hour after administration， blood was sampled from abdominal aorta after anesthesia for the measurement of hormone levels by radioimmunoassay， and ovaries were sampled， embedded， sliced， and stained with haematoxylin-eosin （HE） for pathological observation. ResultThe model group had higher level of luteinizing hormone （LH， P<0.05） and lower level of estradiol （E2， P<0.05） than the blank group. The SWT high-dose group and low-dose group had lower LH levels （P<0.05） and higher E2 levels than the model group （P<0.05）. SWT reversed the elevation in follicle-stimulating hormone （FSH） and LH levels and the decline in E2 and progesterone （P） levels caused by TWP to some extent. There were a large number of follicles at different developmental stages in the blank group， while atretic follicles increased significantly in the model group. A large number of mature follicles， secondary follicles， and primary follicles were observed in the high-dose SWT group， and primordial follicles， secondary follicles， and increased corpus luteum in the low-dose SWT group. Compared with that in the blank group and the administration group， the abundance of Verrucomicrobia and Epsilonbacteraeota in the model group significantly reduced. Compared with the blank group， the model group had different intestinal flora in phylum， class， order， family， and genus levels. Specifically， the model group had increased proportions of Firmicutes and Bacteroidetes. After TWP modeling， the abundance of Lachnospiraceae decreased significantly while that of Ruminococcaceae UCG-005 increased significantly. SWT groups， blank group， and model group can be clearly distinguished， and SWT groups had a tendency to approach the blank group. ConclusionSWT may improve the ovarian function of rats with TWP-induced DOR by regulating intestinal flora diversity.

ObjectiveTo investigate the protective effect of Zuoguiwan against 60Co-γ ray-induced premature aging of rats based on the phosphatidylinositol-3-kinases/protein kinase B/mammalian target of rapamycin （PI3K/Akt/mTOR） signaling pathway. MethodSixty sexually mature female SD rats were irradiated with 60Co-γ rays （6.0 Gy， LD40） for 24 h at one time. Then they were randomized into model group， Bujiale group （0.18 g·kg-1·d-1）， Bujiale （0.09 g·kg-1·d-1） + high-dose Zuoguiwan group （23.625 g·kg-1·d-1）， high-dose Zuoguiwan group （23.625 g·kg-1·d-1）， medium-dose Zuoguiwan group （9.45 g·kg-1·d-1）， and low-dose Zuoguiwan group （4.725 g·kg-1·d-1）. The administration （once a day） lasted 21 days. Serum indexes ［follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， and estradiol （E2）］ of rats were detected by enzyme-linked immunosorbent assay （ELISA）， and morphological changes of ovarian tissues were observed based on hematoxylin and eosin （HE） staining. The apoptosis rate of granulosa cells was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling （TUNEL） and the protein expression of phosphorylated （p）-PI3K， p-Akt， p-mTOR， B-cell lymphoma-2 （Bcl-2）， and Bcl-2-associated X protein （Bax） in ovarian tissues by Western blot. ResultCompared with normal group， model group demonstrated increase in serum FSH （P<0.01）， decrease in E2 （P<0.05）， and reduction of follicles and luteum in early ovary （P<0.01）. Moreover， the elevation of apoptosis rate of granulosa cells （P<0.01）， down-regulation of p-PI3K， p-Akt， p-mTOR， and Bcl-2 in ovarian tissue， and increase in expression of Bax were also observed in the model group as compared with the normal group （P<0.01）. In comparison with the model group， the administration groups showed rise of the number of early ovarian follicles， decrease in the apoptosis rate of granulosa cells， increase in the expression of p-PI3K， p-Akt， p-mTOR， and Bcl-2， and down-regulation of Bax， particularly the Bujiale + high-dose Zuoguiwan group（P<0.05，P<0.01）. ConclusionZuoguiwan protects radiation-damaged ovary by activating the expression of PI3K/Akt/mTOR protein in ovarian tissue， increasing Bcl-2， and inhibiting the expression of Bax.

ABSTRACT
Esse artigo busca analisar o padrão de consumo em diferentes arranjos domiciliares no Brasil, a partir de dados da Pesquisa de Orçamentos Familiares (POF) de 2008-2009. Para isso, foram estimadas curvas de Engel considerando o tipo de arranjo domiciliar, dentre outras variáveis demográficas. Os resultados indicaram a existência de diferenças no padrão de consumo das famílias associadas ao sexo do responsável pelo domicílio, sobretudo nos arranjos "monoparental" e "unipessoal". Essas diferenças são mais evidentes sobre as despesas com habitação, saúde e educação/recreação, em que os gastos mensais per capita são muito menores para os tipos "monoparental masculino" e "unipessoal masculino" em relação ao "monoparental feminino" e "unipessoal feminino". Além disso, verificou-se que a composição da família (presença de filhos, idosos) e o seu tamanho afetam as decisões de consumo das famílias, em que a existência de crianças aumenta os gastos per capita com habitação e saúde e a presença de idosos leva a uma expansão dos gastos com saúde. Quanto ao tamanho da família, há indícios de que as famílias maiores podem se beneficiar dos ganhos de economia de escala e consumo conjunto em relação às despesas com habitação, alimentação e transporte.
The goal of this article was to analyze the pattern of consumption in different household living arrangements in Brazil using data from the 2008-2009 Brazilian Family Budget Survey (POF). We estimated Engel Curves taking into account the type of household living arrangement, among other demographic variables. Results indicated the existence of differences in the patterns of consumption of families associated to the gender of the person in charge of the household, especially in "single parent type with children" and "one person households" living arrangements. These differences are most evident in expenditure on Housing, Health and Education-recreation, in which the monthly per capita expenditure is much lower for single fathers and men living alone relative to single mothers and women living alone. In addition, we verified that family composition (presence of children, seniors) and their size affect household consumption decisions, in which the existence of children increases per capita expenditures on Housing and Health and the presence of seniors leads to an expansion of Health spending. With regard to family size, there are indications that families can benefit from economies of scale and joint consumption gains relative to Housing, Food and Transportation.

Además, se verificó que la composición de la familia (presencia de hijos, ancianos) y su tamaño afectan las decisiones de consumo de las familias, en que la existencia de niños aumenta los gastos per cápita con vivienda y saludy la presencia de ancianos, que lleva a una expansión de los gastos de salud. En cuanto al tamaño de la familia, existen indicios de que las familias pueden beneficiarse de las ganancias de economía de escala y consumo conjunto en relación con los gastos de vivienda, alimentación, transporte.

Objective To compare different regimens of intraperitoneal injection of cyclophosphamide (CTX) to establish a rabbit model of premature ovarian failure (POF), and provide a useful experimental tool for further research of premature ovarian failure. Methods A total of twenty-one 5-6 months old rabbits were randomly divided into 4 groups. The group A (normal control group) included 3 rabbits without any treatment. The group B (the first model group) included 6 rabbits, received a single intraperitoneal injection of 50 mg/kg cyclophosphamide. Six rabbits in the group C (the second model group) were injected with 50 mg/kg cyclophosphamide once daily for 2 days. The group D (the third model group, also n=6) was injected with 50 mg/kg cyclophosphamide on the first day and then followed by 8 mg/ (kg·d) injection q.d. in the 14 consecutive days. Body weight and ovary weight of the rabbits in each group were measured, and the changes of body weight and the ovary index were analyzed. Morphological changes of the ovarian follicles were observed by HE staining and the numbers of normal and abnormal follicles at different developmental stages were counted and analyzed. Cell apoptosis was analyzed by TUNEL staining and changes in the serum levels of estradiol (E2) were detected by ELISA. Results The body weight of rabbits in both groups B and group C was not significantly changed during the experimental period (P＞ 0. 05). Rabbits in the group D showed a slight growth (P ＜ 0. 05) and high mortality. The ovary index in group C was significantly lower than that in the group A (P ＜ 0. 05). The ratios of abnormal primordial and primary follicles in groups B and C were significantly increased (P ＜ 0. 017), and the ratio of abnormal primordial follicles in the group C was increased more significantly (P ＜ 0. 017). However, there was no significant difference in the ratios of abnormal primary follicles between groups B and C (P＞ 0. 017). Among the groups A, B and C, there was no significant difference in the ratios of abnormal secondary and antral follicles (P＞ 0. 05). Apoptosis mainly occurred in granulosa cells of the ovarian follicles. The apoptosis rate of groups B and C was significantly higher than that in the group A (P ＜ 0. 05), and the apoptosis rate of group C was higher than that in the group B (P ＜ 0. 05). In the group B, the serum E2 level reached the peak value on the 7th day, significantly higher than that on the 35th day (P ＜ 0. 05), and then the level was decreased gradually. In the group C, the E2 level was continuously decreased and the level on the last day before drug injection was significantly higher than that at the 35th day (P ＜ 0. 05). Conclusions Intraperitoneal injection of 50 mg/kg cyclophosphamide once daily for 2 days is a most suitable method for the establishment of rabbit model of premature ovarian failure (POF).

Reinforcing kidney-yin for kidney-yin deficiency; reinforcing kidney-yang for kidney-yang deficiency; reinforcing kidney-yin and yang for deficiency of kidney-yin and yang; tonifying the kidney essence and soothing liver-qi stagnation for deficiency of kidney and liver depression. [Conclusion] Treatment of premature ovarian failure is based on tonifying kidney, supplement on soothing liver, while some change therapies, should combine disease with syndrome.
ABSTRACT
Premature ovarian failure (POF) is defined as the complete cessation of menses less than 40 years of age. The criteria are more than four months of amenorrhea, with serum follicle stimulating hormone value of >40 mIU/mL and the frequency of POF is about 1% of all women. Although the etiologies of POF remain unknown, suggested factors are genetic, autoimmune, chemotherapy, radiotherapy and environmental toxins. The cytogenetic abnormalities predominantly concern the X chromosome, including Turner syndrome, Fragile X syndrome and deletion, translocation, or duplication of X chromosome. We report a very rare case of premature ovarian failure with the following karyotype: 46,X,dup(Xq), and report it with a brief review of literature.

La Falla Ovárica Prematura (FOP) es el cese de la menstruación antes de los 40 años. También fue denominada como Menopausia Precoz. Esta patología afecta al 1 ó 2 % de las mujeres menores de 40 años. Existen distintas causas por las cuales se puede producir una FOP, pero las más frecuentes son las inmunológicas, farmacológicas y genéticas. De las causas farmacológicas, la principal es la quimioterapia. Existen muchos genes candidatos para la FOP, razón por la cual es necesario encontrar para, cada población, que mutaciones o polimorfismos correlacionan mejor con el fenotipo. El tratamiento de la FOP debe estar apuntado a prevenir no sólo las enfermedades a largo plazo sino que, además, debe lograr una buena calidad de vida.
Premature Ovarian Failure (POF), also called Precocious Menopause, is the cessation of the ovarian function prior to the age of 40. This pathology affects 1-2 % women below 40 years of age. There are many factors inducing POF, however most frequent are of immunological, pharmacological and genetic origin. Chemotherapy is the most common pharmacological cause. There are many candidate genes for inducing POF, which it makes necessary to find in every population mutations or polymorphisms that best correlate with the phenotype. Treatment of POF must be directed not only to prevent long term pathologies but also to achieve a good quality of life.
ABSTRACT
OBJECTIVE: To evaluate the incidence of the +769 G/A mutation of inhibin-alpha gene in Korean patients with idiopathic premature ovarian failure. DESIGN: DNA analysis of the mutation. METHODS: One hundred patients with idiopathic premature ovarian failure (POF) were recruited. Patient with known causes of premature ovarian failure were excluded: cytogenetic abnormalities, prior chemotherapy, prior bilateral oophorectomy and autoimmune disease, etc. DNA was extracted from peripheral blood and the +769 G/A variant of Inhibin-alpha gene (INH-alpha) was analyzed by polymerase chain reaction (PCR) and restriction fragment length polymorphism using restriction enzyme BbvI. RESULTS: We didn't find any case of +769 G/A variant in Inhibin-alpha gene in 100 Korean patients with idiopathic POF. CONCLUSION: This result suggests that in contrary to the recent data reported on the Asian population, the +769 G/A variant in inhibin-alpha gene may not exist in Korean patients with idiopathic POF.

Premature ovarian failure (POF) is menopause before the age of 40 years. The frequency of POF is about 1% of all women. Recently inhibin alpha gene (INHalpha) has been indicated as candidate in POF pathogenesis. Inhibin, a glycoprotein, is a gonadal hormone, which can inhibit the synthesis and secretion of pituitary follicle-stimulating hormone (FSH), which has an important role in the recruitment and development of ovarian follicles during the folliculogenesis. G769A variation of INH alpha, alanine, is highly conserved across species, and has an important role of its receptor binding. We screened a G769A transition in the INHalpha from the total population of the patients of 84 women with POF and 100 normal fertile women. We found no variation between the normal subjects and the POF patients. G769A variation of INHalpha is rare in Korea women with POF.

OBJECTIVE: This study was performed to determine whether the FSH receptor mutation is present in infertile Korean patients with 46,XX premature ovarian failure (POF) women. METHODS: The variant of FSH receptor exon 10 in thirteen 46, XX idiopathic POF and 4 healthy fertile (control) women were studied. Missense mutation in Exon 10 was detected in POF patients and healthy fertile women by polymerase chain reaction-single stranded conformation polymorphism (PCR-SSCP). RESULTS: The variant types of FSH receptor exon 10 (Thr307Ala; A919G) were found in healthy fertile (control) and POF women. CONCLUSIONS: This mutation may not be specific in POF patients and further study is needed in fertile (control) and POF women.

The change of T cell subsets of peripheralblood were tested in 12 patients with prematureovarian failure (POF), among them 10 patients superoxide dismutase (SOD) activity in erythrocytewas also tested. The results showed that the num-ber of T_3, T_4 cells T_4/T_8 ratio and SOD activitywas significantly lower in patients with POF thanin normal controls, which indicated that the func-tion of proliferation and differentiation of T lym-phocyte was inhibited, the immunoregulation wasinbalanced and the ability of resistance to lipid per-oxidation was lower in patients with POF. There-fore, the results suggests that T cell subsets andSOD activity testing in patients with POF have val-ue in the investigation of the cause of the deseaseas well as in the diagnose and treatment.
