BACKGROUNDGender is one of the risk factors accounting for the high prevalence of adolescent myopia. Considerable research results have shown that myopia incidence of female is higher than that of male. This study aimed to analyze the correlation between ocular parameters and serum estrogen level and to investigate the vision changes along with estrogen change in menstrual cycle of adolescent females.

METHODSA total of 120 young females aged between 15 and 16 years, diagnosed with myopia were recruited. Spherical lens, cylindrical lens, axis, interpupillary distance (IPD), and vision in each tested eye of the same subject were measured by automatic optometry and comprehensive optometry, with repetition of all measurements in the menstrual cycle of the 2 nd or 3 rd days, 14 th days, and 28 th days, respectively. Serum estradiol (E 2 ) levels were assayed by chemiluminescence immunoassay at the same three times points of the menstrual cycle mentioned above.

RESULTSIn young females with myopia, the spherical lens showed a statistically significant difference among all different time in menstrual cycle (all P < 0.0001). The cylindrical lens, axis, and IPD were changed significantly during the menstrual cycle (P < 0.05). The vision of the three different time points in menstrual cycle had a significant difference (χ2 = 6.35, P = 0.042). The vision during the 14 th and 28 th day was higher compared to that on the 2 nd or 3 rd days (P = 0.021). Serum E 2 levels were significantly different at different time points in menstrual cycle (P < 0.05). E 2 levels reached its maximum value on the 14 th day and the minimum value on the 2 nd or 3 rd day.

CONCLUSIONSIn adolescent females, the spherical lens and other related ocular parameters vary sensitively with different levels of E 2 in menstrual cycle. Vision in late menstrual stage is significantly higher than that in premenstrual stage.

OBJECTIVETo investigate the relation of peripheral blood estradiol, progesterone and testosterone levels with irritable bowel syndrome (IBS).

METHODSForty-eight patients with IBS identified according to Rome II diagnostic criteria and 30 healthy subjects as controls were analyzed for peripheral blood sex hormone levels by radioimmunoassay and corresponding software.

RESULTSIn male patients with IBS, blood testosterone level was significantly lower than that of the control group (P<0.05), but blood estradiol and progesterone showed no significant differences between the two groups (P>0.05). In the female patients, blood estradiol level was significantly lower than that of the control group (P<0.05), whereas blood progesterone and testosterone levels had no significant differences between the two groups (P>0.05).

CONCLUSIONPeripheral blood testosterone level in male IBS patients and estradiol level in female patients are lower than those of healthy subjects, suggesting that IBS might be associated with blood sex hormone disorder.

Serum levels of LH, FSH and prolactin and plasma levels of estradiol and progesterone were measured by radioimmunoassay from 8 healthy volunteers on no medication for at least 3 months prior to study and with histories of regular menstrual cycle. The following criteria were used to define a normal menstrual cycle:1) mid-cycle LH surge, 2) luteal phase duration between 12 and 16 days, 3) plasma progesterone levels above 5 ng/m1 5-10 days after LH surge. Six of eight cycles studied were considered normal. Serum levels of LH from 6 women were fair1y constant through the cycle, except at midcycle, when a surge occurred. The rapid increase of LH secretion was during the late follicular phase with a mean peak value of 147.5 mIU/ml. Concentration of FSH started to rise after the onset of menses and decreased slight1y during the late follicular phase. FSH rose sharply at midcycle with a mean peak value reaching 36.8 mIU/ml. Following the midcycle FSH and LH surge, FSH and LH decreased sharply and remained at lower concentration during the luteal phase than during the follicular phase. Serum prolactin concentrations fluctuated throughout the menstrual cycle. There was no peak value of prolactin concomitant to the LH peak. Plasma estradiol gradually increased during the follicular phase reaching a maximum of 354.3 pg/ml prior the midcycle LH surge. Following its peak, the level of estradiol dropped sharply and started to increase from the 3rd day after LH peak, rising to 235.9 pg/ml during the midluteal peak. Plasma progesterone levels remained consistently low during the follicular phase and started to rise after the midcycle surge of LH. This rise persisted from day 5 to day 9 after the LH surge, showing a mean value of 26.1 ng/m1. Afterward, a sharp decline occurred resulting in menstruation. Two cycles studied were considered abnormal. Both cycles showed a "short luteal phase".

OBJECTIVETo find the objective indices for traditional Chinese medicine (TCM) pattern identification in women patients with climacteric hypertension (CH) by exploring the relationship between TCM pattern with blood levels of sex hormone, lipid and glucose.

METHODSTCM syndrome differentiation was made in 75 women CH patients, 43 as yin-deficiency with inner dryness pattern (YDD) and 32 as non-YDD, and correlation analyses were conducted on TCM patterns and blood levels of estradiol (E2), lipids and glucose.

RESULTSBesides the level of E2 in YDD was lower than that in non-YDD [(112.26 -/+ 66.81) pmol/L vs (146.69 +/- 83.59) pmol/L, P < 0.05), no difference between the two patterns was found in the other indices measured (P > 0.05). Further subunit analysis showed that in patients with CH grade 1, blood levels of total cholesterol (TC), high density lipoprotein (HDL) and apoprotein A-I (ApoA-I) were higher in the 13 patients of YDD than those in the 9 of non-TDD (P < 0.05); in patients with CH grade 2, levels of E2, progesterone (T), HDL and ApoA-I were lower but level of follicle stimulating hormone (FSH) was higher in the 20 YDD than those in the 10 non-YDD (all P < 0.05); while in patients with CH grade, no statistically significant difference was shown between 3 patients of 10 with YDD and 13 with non-YDD in all the indices measured (P > 0.05).

CONCLUSIONBlood level of E2 shows different characteristics between CH patients of YDD and non-YDD patterns, suggesting that it may provide some help to syndrome micro-differentiation, and taking it as an objective index for syndrome typing of climacteric hypertension in female is considerable.

OBJECTIVETo explore the relationship between the levels of estrogen (E2) and progestogen (P), expression of estrogen receptor (ER) and progesterone receptor (PR) and cervical cancer.

METHODSA case-control study with hospital and community controls was employed. The levels of serum estrogen and progesterone were detected by enzyme linked immunosorbent assay (ELISA) for 141 cervical cancer cases, 137 uterine myoma patients as controls and 129 health women as controls. ER and PR were measured by immunohistochemistry sABC in cervix tissues from patients with cervical cancer and uterus myoma as well.

RESULTSThe levels of estrogen (47.49 ng/mL) and progesterone (2.34 pg/mL) in cases were significantly higher than those in both control groups. The association between estrogen and cervical cancer was significant both before and after menopause-adjusted, with over 89% of attributable risk percentage (ARP), and showed a dose-response relation. Using the lowest value of 2 pg/ml in follicular phase as cut off point for progesterone, there were no statistically significant difference between cases and controls, and neither in progesterone nor in premenopausal. The expressions of ER and PR in cases were lower than those in controls, even after being menopause-adjusted.

CONCLUSIONThe high level of endogenous estrogen and progestogen might increase the risk of cervical cancer. Compared with progestogen, estrogen showed a higher risk that was not influenced by menopause. In some sense, ER and PR may exert certain protective effect on progressing of cervical carcinogenesis.

OBJECTIVETo investigate the effects of carbaryl on serum steroid hormone and function of antioxidant system in female Sprague Dawley rats.

METHODSCarbaryl was administrated to the adult female rats at doses of 0, 1.028, 5.140 and 25.704 mg x kg(-1) x d(-1) for 30 d. Vaginal smears of rats were taken to determine estrous cycle. Serum 17beta-estradiol (E(2)) and progesterone (P(4)) concentrations were measured by radioimmunoassay. The activities of superoxide dismutase (SOD) and glutathione-s-transferase (GST), and the levels of malondialdehyde (MDA) and glutathione (GSH) were measured by spectrophotometry.

RESULTSThe number of estrous cycle in exposed groups were obviously lower than in control group (P < 0.05, P < 0.01). Body weight gain in high dose group (25.704 mg x kg(-1) x d(-1)) was significantly lower than that in control. Meanwhile, the organ coefficient of ovary and uterus declined in a dose-dependent manner. Serum E(2) level [(19.93 +/- 2.21) nmol/L] in 25.704 mg group was lower than in control group [(28.76 +/- 6.12) nmol/L, P < 0.05], and P(4) level (1.21 +/- 0.40) nmol/L in 1.028 mg group was higher than that in control group [(0.63 +/- 0.39) nmol/L, P < 0.05]. The activity of SOD first reduced then rose in ovary, and first rose then reduced in serum. The contents of MDA increased in ovary, while decreased in the serum. GSH contents and GST activity increased in ovary, while in serum GSH contents decreased and GST activity first increased then decreased.

CONCLUSIONCarbaryl could disrupt estrous cycle and affect serum steroid hormone, and the function of antioxidant system in female SD rats.

OBJECTIVE: To explore the levels of sex hormones in female patients with systemic lupus erythematosus (SLE) and its role in the genesis of SLE. METHODS: The serum levels of estradiol, estriol, testosterone, progesterone, and prolactin were determined by electro-chemiluminescence immunoassay in 98 female patients with SLE and compared with those of 38 healthy women. RESULTS: The serum levels of estradiol, estriol, progesterone, and prolactin were significantly higher than those in the healthy women (P <0.05). The serum levels of estradiol, progesterone, and prolactin in patients with SLE in 25 to 34 year old group were higher than the other age groups and the control group (P < 0.05), and the serum levels of estradiol and prolactin in patients with active phase of SLE were significantly higher than those in patients with stable phase of SLE (P <0.05). CONCLUSION The levels of sex hormones have a close corretation with the genesis and development of SLE.

Angiomyofibroblastoma (AMFB) is an uncommon benign mesenchymal tumor. AMFB occurs almost in the vulvo-vaginal area of women. The gross features of AMFB are well-circumscribed so it clinically is often thought as Bartholin gland cyst or aggressive angiomyxoma. Usually, most tumors grow slowly, and patients do not feel pain. It also has low tendency for local recurrence. The histologic findings of the tumors are abundant thin-walled blood vessels with hypocellular and hypercellular areas. Almost all tumor cells have immunoreactivity for both desmin and vimentin. It also has estrogen and/or progesterone receptors, but staining for cytokeratin is negative. Here is a case of AMFB of the vulva occurring in a 40-year-old woman, involving the right labia majora. The patient described that her vulva mass grew in about few months. The maximum dimension of the tumor was measured as 2 cm, and we resected the tumor one month after as her second visit.

OBJECTIVETo study the mechanisms of tongjingning granule (TJN) on primary dysmenorrhea (PD).

METHODSOne hundred and twenty PD patients were treated with TJN, and 40 patients treated with aspirin as controls. The levels of serum estrogen (E2) and progestin (P) content in the luteal metaphase and anaphase (MI/AI) as well as endothelin (ET) and calcitonin gene related peptide (CGRP) in the metaphase and menstrual stage before and after treatment in partial patients were determined.

RESULTSThe therapeutic effect , and the curative markedly-effective rate and improvement rate of main accompanied symptoms of severe and moderate PD patients in the treated group were superior than those in the control group (P < 0.01). The level of E2 and ET were significantly decreased, and the content of P and CGRP were significantly increased in the treated group after treatment respectively (P < 0.01).

CONCLUSIONJTN not only can regulate ovarian hormone, ET and CGRP, but shows advantages in adjusting spirits and emotions, improving homeostasis and consolidating the therapeutic effect.
