Lactobacilli have been used to treat many gastrointestinal disorders. But the outcome of Lactobacilli are strain specific. The strain Lactobacillus Fermentum, HY01, (LF-HY01) has a good performance in the environment of gastrointestinal tract. In this study, the aim is to investigate the preventive effects of LF-HY01 against activated-carbon-induced constipation in mice. Mice are randomized into four groups. Normal group was fed a normal diet, model group also has the same with activated carbon treatment, and low and high concentration groups are treated with LF-HY01. We have determined many indexes such as body weight, water content in faeces, defecation conditions, the level of small intestinal villi damages and levels of various neurotransmitters in serum, including motilin (MTL), gastrin (GT), endothelin (ET), somatostatin (SST), acetylcholinesterase (AchE), substance P (SP), and vasoactive intestinal peptide (VIP). LF-HY01 has no significant difference in each group, but it can significantly improve water content of faeces, defecation time of first black stool and activated carbon propelling rate in small intestine as compared of model group. Furthermore, LF-HY01 can effectively prevent small intestinal villi damages, which is less than that of model group. Moreover, LF-HY01 has the consistency to increase the levels of MTL, GT, ET, AchE, SP and VIP, and LF-HY01 can also have the ability to reduce the level of SST. These results suggest that Lactobacillus Fermentum, HY01, has a great impact in enhancing intestinal peristalsis ability and has the ability to prevent from activated-carbon-induced constipation in mice.

Understand the dietary conditions of freshmen in a medical university, and explore the correlation between their dietary patterns and physical fitness levels. A dietary frequency survey was carried out among 2125 freshmen to evaluate their nutrient intake. Factor analysis was performed to extract common factors and determine dietary patterns. According to the "National Standards for Students" Physical health", the freshmen were tested for physical fitness, and the correlation analysis was conducted between the results of physical fitness score and dietary patterns. Four dietary patterns were identified by factor analysis, which were healthy dietary pattern (HDP), high fat and high sugar pattern (HFP/HSP), preserved food pattern and trace element pattern (TEP). Spearman rank correlation analysis showed the HDP and TEP were significantly positively correlated with the fitness test scores (r=0.064,0.062, p< 0.01), while the HFP and HSP was significantly negatively correlated (r=-0.057,p<0.01). Our results suggest that a healthy diet was associated with improved physical fitness performance, while a high intake of fatty and sweetened foods was associated with the opposite.

To investigate the effect of high salt diet (HSD, 8% NaCl) on the letrozole induced PCOS mice. At the total of experimental periods (35 days), all female C57BL/6J mice were randomly divided into normal groups, PCOS group (ingested letrozole daily for 21 days) and HSD+PCOS group. The body weight (BW) and histologic changes were evaluated. The serum levels of testosterone (T), LH, E2, FSH, INS, TG, TC, LDL, HDL were determined by ELISA kits. Compared with normal groups, the BW, T, LH, INS, TG, TC LDL-C in PCOS rats were significantly increased, and the levels of E2, FSH and HDL-C were significantly decreased. In addition, compared with the PCOS group, the BW, T, LH, INS, TG, TC LDL-C in HSD+PCOS rats were significantly increased, and the levels of E2, FSH and HDL-C were significantly decreased. Our results showed that HSD exacerbates metabolic disorders and hormonal imbalances in PCOS mice.

Background: This study aimed to establish a nomogram by combining clinicopathologic factors with overall survival of stage IA-IIB cervical cancer patients after complete resection with pelvic lymphadenectomy. Materials and Methods: This nomogram was based on a retrospective study on 1,563 stage IA-IIB cervical cancer patients who underwent complete resection and lymphadenectomy from 2002 to 2008. The nomogram was constructed based on multivariate analysis using Cox proportional hazard regression. The accuracy and discriminative ability of the nomogram were measured by concordance index (C-index) and calibration curve. Results: Multivariate analysis identified lymph node metastasis (LNM), lymph-vascular space invasion (LVSI), stromal invasion, parametrial invasion, tumor diameter and histology as independent prognostic factors associated with cervical cancer survival. These factors were selected for construction of the nomogram. The C-index of the nomogram was 0.71 (95% CI, 0.65 to 0.77), and calibration of the nomogram showed good agreement between the 5-year predicted survival and the actual observation. Conclusions: We developed a nomogram predicting 5-year overall survival of surgically treated stage IA-IIB cervical cancer patients. More comprehensive information that is provided by this nomogram could provide further insight into personalized therapy selection.

To investigate the effects of AMP on letrozole-induced PCOS rats. All SD rats were randomly divided into normal, PCOS, metformin group (Met, 265 mg/kg) and AMP group (1 g/kg) and weighed every three days. After 21 days of continuous administration, oral glucose tolerance test was performed, and the blood glucose(BP) level was measured. After execution, calculate the relative weight of bilateral ovaries. Serum levels of FSH, LH, E2, T and FINS were detected by ELISA assay. Serum levels of TC, TG, HDL-C and LDL-C were detected by the kit and calculated the LH/FSH ratio and HOMA-IR level. Compared with the normal group, body weight and relative weight of ovaries, BP level and serum levels of T, LH, LH/FSH ratio, FINS, HOMA-IR, TC, TG, LDL-C, and E2, FSH, HDL-C in model group increased. Compared with the PCOS group, body weight in the Met group and AMP group was lower, BP level and serum levels of T, LH, FINS, HOMA-IR and LDL-C in the Met group and AMP group were significantly lower and the level of HDL-C was higher. Armillaria mellea polysaccharides can improve hormone disturbance, glucose metabolism and abnormal lipid level in letrozole-induced polycystic ovary syndrome model rats.

To investigate the effect of ACP on letrozole-induced PCOS rats. All rats were divided into normal groups, PCOS group, metformin group and ACP group. The body weight (BW) was recorded every three days, and the final body weight as well as ovarian weight were recorded. Serum levels of TC, TG, HDL-C, LDL-C and E2, T, FSH and LH were measured by ELISA assay, and the LH/FSH ratio was calculated. The results showed that ACP decreased the BW and the ratio of ovarian to BW. Compared with the normal group, the serum levels of T, LH, LH/FSH, TG, TC, LDL-C increased, and the levels of FSH, E2, HDL-C decreased in PCOS group. ACP effectively improves the serum levels of FSH, LH/FSH, TG, TC, LDL-C and other related factors. The results of H&E staining of ovarian tissues showed that the ACP group showed different degrees of improvement in the reduced number of corpus luteum, thinning of granulosa cell layer, follicular capsular dilatation and follicular atresia. ACP not only reduces BW and the ratio of ovarian to BW, but also it can elevate the level of FSH and reduce LH/FSH, TG, TC and HDL-C levels. Furthermore, ACP can protect ovarian tissue to some extent.

This study was to investigate the ameliorative effect of GFPS on clinical symptoms in letrozole(1 mg/kg)-induced PCOS rats. The female SD rats were classified into 4 groups as follows: the normal group (gavaged with saline), the PCOS group(ingested letrozole daily for 21 days). Normal group and metformin group gavaged with letrozole followed by metformin (265 mg/kg) and GFPS(600 mg/kg), respectively. All rats were weighed every 3 days until the end of the experiment. The ovaries, perirenal, abdomen and periuterine fat were removed and the relative weights (g/bw×100) were calculated. Serum levels of FSH, LH, E2, T, TG, TC, LDL-C were measured by ELISA and calculated the LH/FSH ratio. GFPS reduced follicle number and increases granulosa cell layer thickness and luteal number. GFPS also reduced the increase of body weight, ovarian and visceral fat weight in PCOS rats (P<0.01). In addition, GFPS reduced the serum levels of T, LH/FSH, TC, TG, LDL-C and LH, and elevated the serum levels of E2 and FSH in PCOS rats. In conclusion, GFPS can improve follicular development and restore body weight, ovarian weight, serum hormone levels and lipid profile in PCOS rats.
