ABSTRACT

Objective@#To explore the correlation between menopausal hormone therapy(MHT)and breast lesions in perimenopausal women,and to provide evidence for safe use of MHT. @*Methods@#The 40-60 year-old women who visited Hangzhou Women's Hospital and met the diagnostic criteria for perimenopausal syndrome were recruited. The intervention group received MHT and was divided into three subgroups according to the MHT regimen:estrogen-progesterone cycle therapy(A),estrogen-progesterone continuous therapy(B),estrogen therapy(C). The control group did not receive MHT. All the patients received regular mammography to quantify and evaluate breast lesions. The generalized estimating equation was used to analyze the changes of breast lesions between different groups.@*Results@#There were 80 cases in the intervention group,with 49 in group A,26 in group B,5 in group C,and 80 cases in the control group. After two years of follow-up,there was no statistically significant differences of time,group and interaction in breast density,volume of breast fibrous tissue and the volume of breast between three intervention groups and the control group(P>0.05); there was no statistically significant differences of group and interaction in positive rate of calcification and breast mass between the intervention group and the control group(P>0.05). @*Conclusion@#Receiving MHT intervention for two years did not increase the risk of breast lesions.

ABSTRACT

The protective effects of Da Chai Hu Granules (DCHKL) on islet cells which were incubated with 4 mmol x L(-1) alloxan (AXN) were studied. The viability of islet cells were measured with MTT. Insulin released into medium and in islets was detected by radioimmunoassay. Cell apoptosis rate was determined by flow cytometry. The expression of anti-apoptotic gene Bcl-2 and pro-apoptotic gene Bax in islet cells were measured with RT-PCR (reverse transcription polymerase chain reaction). Serum containing DCHKL can promote the activity of islet cells significantly (P < 0.01). Basal insulin secretion and high glucose-stimulated insulin secretion increased significantly (P < 0.01). Serum containing DCHKL can inhibit apoptosis of islet cells, the ratio of apoptosis was decreased. Serum containing DCHKL increased expression of Bcl-2 mRNA and decreased expression of Bax mRNA. DCHKL can significantly promote proliferation of islet cells and increase the amount of basal secretion of pancreatic islet cells and high glucose-stimulated insulin secretion. The expression of Bcl-2 increased significantly. The expression of Bax decreased significantly. DCHKL have a protective effect on the islet cells.

ABSTRACT

<p><b>OBJECTIVE</b>To study the mechanism of protective effect of Jinqiaomai (JQM) on lung injury induced by Klebsiella pneumonia in rats.</p><p><b>METHOD</b>The model of rats with Klebsiella pneumonia was established. The male SD rats were randomly divided into control group, model group, JQM (6, 3, 1.5 g x kg(-1)) three groups, levofloxacin (25 mg x kg(-1)) group, JQM (3 g x kg(-1)) + levofloxacin (25 mg x kg(-1)) group. The contents of IL-1beta, ICAM-1 and INF-gamma in the lung tissue homogenate were measured by radio-immunoassay and Elisa. TLR2/4 mRNA and MyD88 mRNA expression were detected by RT-PCR. IkappaB-alpha expression was detected by Western Blot.</p><p><b>RESULT</b>The rats of model group had obvious lung injury, but those of JQM, JQM + levofloxacin and levofloxacin groups had less injury. The contents of IL-1beta, ICAM-1 and INF-gamma in lung tissue homogenate and the expressions of TLR2/4 mRNA, MyD88 mRNA and IkappaB-alpha in lung of model group were significantly higher than those in the control group (P < 0.05 or P < 0.01), while IL-1beta, ICAM-1 and INF-gamma of JQM groups were significantly lower than those of model group (P < 0.05 or P < 0.01). The expressions of TLR2/4 mRNA, MyD88 mRNA and IkappaB-alpha of JQM (6.3 g x kg(-1)) groups were significantly lower than those of model group(P <0. 05 or P <0. 01).</p><p><b>CONCLUSION</b>The lung injury induced by Klebsiella pneumonia is related to TLR2/4, MyD88 mRNA and IkappaB-alpha. To decrease the excessive expression of TLR2/4, MyD88 mRNA and IkappaB-alpha might be the main mechanism of protective effect of Jinqiaomai on lung injury.</p>

ABSTRACT

Objective:To investigate the metabolism changes in corpus striatum of hemiparkinsonian monkeys after chronic high frequency stimulation in subthalamic nucleus (STN) by SPECT and PET imaging. Methods: Two hemiparkinsonian monkeys, induced by unilateral internal carotid artery infusion of 1-methyl-4-phenyl-1,2,3,6-tetrahydropy-rindine (MPTP), were implanted with stimulation electrodes in STN of lesioned side according to stereotaxic atlas of the monkey brain. SPECT and PET examination were performed before and 1, 3 months after stimulation. Results: PD symptoms of monkeys, including rigidity, bradykinesia and gait abnormality, were significantly improved. SPECT imaging indicated that dopamine transporter (DAT) binding to corpus striatum in stimulated side increased and D 2 receptor (D 2 R) decreased to the level of unlesioned side after stimulating. PET imaging showed that right corpus striatum had lower density than left corpus striatum before stimulation. One month after chronic high frequency stimulation, bilateral corpus striatum had low density, but the right was slightly higher than that of the left;3 months after stimulation the right was obviously higher than the left . Conclusion: The symptoms of hemiparkinsonian monkeys can be obviously improved by STN deep brain stimulation(DBS). The increased DAT binding and glucose metabolism of corpus striatum in stimulated side and the decreased D 2 R binding after stimulation suggest that the activity of striatal dopaminergic system may be promoted by STN DBS.
