Clinical Medicine of China 2014;30(8):863-865
Objective To investigate the effect on short-term continuous subcutaneous insulin infusion (CSII) treatment on beta-cell function,serum triglyceride(TG),C-reactive protein(CRP) and serum insulin like growth factor-1 (IGF-1) of newly diagnosed type 2 diabetes mellitus(T2DM) patients.Methods Thirty-two newly diagnosed T2DM patients with fasting plasma glucose(FPG) > 11.1 mmol/L were treated with CSII for 2 weeks.FPG,2 h postprandial blood glucose (2hPG),fasting insulin (FINS),2 h postprandial insulin (PINS),fasting C peptide (FC-P),2 h postprandial C peptide (PC-P),glycosylated hemoglobin (HbA1 c),Homa-β,Homa-R,TG,CRP and IGF-1 were measured and compared before and after CSII.Results (1) Compared with that of before treatment,the levels of FPG,2hPG,HbA1c,PINS and PC-P in patients after treatment were dramatically improved(t =12.04,11.57,7.61,20.77,6.16; P < 0.05),and Homa-β increased from (23.0 ±16.2) to (71.0±23.8)(t=9.46,P<0.05),while Homa-IR significantly decreased from (6.8 ±2.1) to (3.9 ± 2.6) (t =4.81,P < 0.05).(2) The levels of TG and CRP significantly decreased from (1.50 ± 0.32) mmol/L,(3.14±1.14) to (1.29±0.31) mmol/L,(1.95 ±0.52) mg/L(t =26.73,23.62;P <0.05).The levels of IGF-1 significantly increased from (341 ± 16) μg/L to (471 ± 17) μg/L (t =8.65,P < 0.05).Conclusion The excellent glycemic control,improvement of lipid metabolism,anti-inflammatory and improvement of beta-cell function can be achieved with short-term CSII intensive therapy in newly diagnosed T2DM patients with severe hyperglycemia.
2.Expression and significance of estrogen receptor- β and tyrosine kinase receptor- B in endometriosis associated ovarian cancer
Chinese Journal of Postgraduates of Medicine 2017;40(5):471-473
Malignant transformation of ovarian endometriosis is known as endometriosis associated ovarian cancer (EAOC). However, the carcinogenic pathways by which EAOC develops remained poorly understood, and numerous studies found the risk factors of malignant transformation. Recent studies have provided evidence that estrogen receptor-β(ER-β) can influence the proliferation, motility and apoptosis of ovarian cancer cells. The signal pathway of tyrosine kinase receptor-B (TrkB)/brain-derived neurotrophic factor (BDNF) has a direct relation with the endometriosis, and its anti-anoikis plays a prerequisite role in proliferation of cancer. In the nervous system, estradiol and estrogen receptor can be combined through a variety of ways to promote BDNF/TrkB high expression and activity enhancement. Therefore,the relationship between high-risk factors of malignant transformation and ER-β expression and ER-β and TrkB/BDNF signal pathways need to be explored in EAOC.

Objective To investigate the expression of neurotrophic tyresine kinase receptor TrkB in the eutopic and ectopic endometium of women with endometriosis and evaluate the role of TrkB in the pathogenesis of endometriosis. Methods Seventeen women with endometriosis and 9 controls were studied. Expression of TrkB was investigated using RT-PCR, immunohistochemistry and Western blot, respectively. Results TrkB mRNA was expressed in eutopic endometrium in secretory phase and ectopic endometium of women with endometriosis, (23.51±0.51)% vs (35.29±0.67) % (P<0.05), but TrkB mRNA expression was not detected in control endometrium and eutopic endometrium in proliferative stage of women with endometriosis by RT-PCR. TrkB was expressed both on membrane (glycosylated receptor) and in cytoplasm (non-glycosylated receptor) of the glandular epithelial cells of ectopic endometium, and more often observed in cytoplasm of glandular epithelial cells of eutopic endometrium in secretory phase of women with endometriosis by IHC. In eutopic endometrium in secretory phase and ectopic endometium of women with endometriosis, the expression of TrkB protein was (0.12±0.02)% vs (0.37±0.01)% (P<0.05) by Western blot. Conclusions There is an overexpression of TrkB in eutopic endometrium in secretory phase and ectopic endometium of women with endometriosis. Full-length (glycosylated receptor) TrkB more often is overexpressed in ectopic endometium of women with endometriosis, and TrkB may act as a pathogenic role in formation of endometriosis.

Objective To study the relationship between the mutation of androgen receptor(AR) gene and the development of human prostat e cancer. Methods All exons of AR gene except trineucl eic acid repeat polymorphism were amplified by PCR and selected by single strand conformation polymorphism( SSCP) in 27 paraffin-embedded slides of human pros tate cancer. The abnormal mobility shifts were further detected by direct DNA c ycle sequencing. Results Three abnormal mobility shifts respectively in exon A.D.G were found by SSCP in three prostate cance r tissues. One point mutation was found in 296 amino acid (C 966→A,Ser29 6Arg) from exon A.This point mutation has not been reported before. Conclusions This mutation might change the transcriptive activity of AR, and it might be correlated to PCa progression.
