Objective:To inverstigate the predictable value of vascular active factors-angiotensin-Ⅱ((AT-Ⅱ)),interleukin-6(IL-6),and insulin-like growth factor-1(IGF-1) for the occurrence of ovarian hyperstimulation syndrome(OHSS) in patients with polycystic ovarian syndrome(PCOS). Methods:Twenty one patients with PCOS,17 patients with polycystic ovary(PCO)and 14 ovarian hyperandrogenism(OHA)and 8 cases of the control were received the intramuscular injection of human choronal gonadotropin(HCG)on the metaphase in natural or induced menstrual cycle.The blood was sampled before the injection and 3,6,12,18 and 24 hours after the injection.AT-Ⅱ,IL-6 and IGF-1 were determined by radioimmunoassay with commercially available kits. Results:The serum levels of AT-Ⅱ after HCG stimulation in PCOS patients was higher than other three groups with statistic significance at 3-hour point.There were comparable serum IL-6 and IGF-1levels among the four groups. Conclusion:Serum AT-Ⅱ may serve as a predictable marker for the occurrence of OHSS in patients with PCOS before ovulation induction.

Objective To study the changes in gene expression profiles of dendritic cells(DCs) during their maturation processes using cDNA microarray.Method DCs were generated from human peripheral blood monocytes induced by GM-CSF and IL-4,and lipopolysaccharide(LPS) was used to induce the maturation of DCs.After inducing for 48h,cells were collected to extract the general RNA.Genes expressions of mature DCs(maDC) and immature DCs(imDC) were analyzed using cDNA microarray,and immature DCs without induction served as control.Results DCs expressed highly surface markers of mature DCs after LPS induction.The studied data showed that among those 165 target genes,a total of 50 genes(30.3%) exhibited differential levels of expression in LPS-induced mature DCs.Thirty-five genes were up-regulated and fifteen genes were down-regulated.Maturation-dependent up-regulation,defined by a differential expression ratio of ≥2,included twelve cytokine and chemokine genes,ten antigen uptake and presentation genes and thirteen signal transduction molecule genes.Reciprocally,maturation-dependent down-regulation,defined by a differential expression ratio of ≤0.5,occurred with two cytokine,five antigen uptake and presentation genes and eight signal transduction molecule genes.Semi-quantitative reverse transcription polymerase chain reaction(RT-PCR) was employed to further confirm the results of cDNA microarray.Conclusion It is suggested that LPS has significant influence on many genes of DCs in their maturing processes.Those changed genes include cytokines,chemokines and their receptors,antigen uptake and presentation molecules and signal transduction molecules.Analysis on these differentially expressed genes is helpful in understanding the maturing processes of DCs.

Objective To explore the effects of comprehensive rehabilitation on nutriture and medical costs in the treatment of patients with dysphagia following stroke. Methods Eighty-seven patients with dysphagia were divided into an intervention group (IG) and a control group (CG). Comprehensive rehabilitation therapy including deglutition training, electric neuromuscular stimulation and acupuncture were used with the IG patients, but not with those in the CG. Nutriture parameters included a biochemistry index and a body measurement index. Medical costs were observed before and after one month of treatment for both groups. Results After one month of treatment, average deglutition scores and nutriture indices were significantly higher in the IG than in the CG. Medical costs for the IG had decreased significantly compared with the CG. Conclusions Comprehensive rehabilitation therapy improved deglutition function and slowed nutriture deterioration, while decreasing medical costs in the treatment of patients with dysphagia following stroke.

Objective The radiotherapy is one of main treatments for patients with malignant tumor and leads to ovarian func-tion decreasing in young women .It is very important to protect ovarian function during the process of radiotherapy .The aim of this study is to investigate the effect of melatonin ( MT) agonist on radiotherapy-induced ovarian function damage in female rats . Methods Thirty SD rats were divided into five groups randomly , which received normal saline, 200 cGy radiotherapy+normal saline, 200 cGy radiotherapy+MT(25 mg/kg), 200 cGy radiotherapy+MT(50 mg/kg), and 200 cGy radiotherapy +MT(100 mg/kg), respectively.All rats were de-capitated two weeks after radiotherapy .Levels of serum follicle-stimulating hormone (FSH) and estradiol (E2) were measured by en-zyme-linked immune sorbent assay method;the number of the primordial follicles , the growth follicles and the mature follicle were ob-served;Caspase3 activity was assayed by spectrophotometry . Results In accordance with the normal control group , RT+MT (100 mg/kg) group, RT+MT (50 mg/kg) group,RT group , serum E2 levels decreased, respectively (6.68 ±0.48, 5.73 ±1.36, 4.26 ±0.44, 2.83 ±0.51)pmol/L;FSH levels increased, respectively (0.340 ±0.011, 0.431 ±0.053, 0.479 ±0.023, 0.604 ± 0.028)ng/mL ;the total number of follicles decreased ,respectively (21.67 ±1.97, 18.00 ±2.28, 15.50 ±1.05, 11.50 ±2.43);Caspase3 activity increased,respectively (0.14 ±0.03, 0.26 ±0.06, 0.36 ±0.05, 0.50 ±0.05).Except FSH had no significant difference between RT +MT(50 mg/kg)group and RT+MT(100 mg/kg) group(P>0.05), the rest indexes had significant difference between the two groups(P<0.05). Conclusion MT can diminish radiotherapy-induced ovarian damage in female rats, it may be related to the mechanism that MT inhibits the radiotherapy-induced activation of Caspase 3.
