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.

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 effect of GLP1 on the blood glucose in type 2 diabetic rats,and its protective effects on the islet B cells.Methods: Thirty rats were divided into three groups: spontaneous type 2 diabetes animal model OLETF rats,GLP-1 [from the twelfth week 56 ?g/(kg?d),sc] therapy group and LETO rats as control.In the 14th and 20th weeks,standard OGTT including fast and 2 h-plasma glucose were measured respectively.In the 14th weeks,3 rats from each group were killed randomly,and the rest of the rats were killed until the 20th week.Immunostaining with the marker of PCNA,TUNEL,and insulin assessed metabolic changes in the islet. Ultrastructure of the B cell was observed with the electronic microscope.Results: In the 14th and 20th week,AUC for insulin were higher in treated animals(10.86?1.56 vs.9.07?1.28,P

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 investigate the effectiveness of microresection combined with radiofrequency ablation under laryngoscope and rigid telescope for laryngeal precancerosis. Methods Fifty-one patients with laryngeal precancerosis, which was diagnosed pathologically, were treated with microresection combined with radiofrequency ablation under laryngoscope and rigid telescope. The patients were followed up for over 6 months. Results During a mean of 26-month follow-up (6 months to 4.5 years), 7 of the patients had recurrence (vocal cord leukoplakia in 3, atypical hyperplasia in 2, and laryngeal papilloma in 2); 4 had carcinomatous change (vocal cord leukoplakia in 1, atypical hyperplasia in 2, and laryngeal papilloma in 1);and 2 patients developed laryngeal web after surgical treatment for bilateral vocal cord leukoplakia. One month after the operation, the Jitter, Shimmer, and NNE were decreased significantly (P

Objective To understand the status and distribution of the Xinjiang Uygur and Han middle-aged and elderly population who suffer from cardio-cerebral vascular disease.Methods From July 2004 to June 2007,multi-stage stratified random cluster sampling methods was adopted to collect the random samples older than 50-year-old suffering from cardiovascular and cerebrovascular disease in South Xinjiang.Results In the 3685 Uygur and Han ethnic elderly people,the prevalence of hypertension,diabetes,lipid disorders,cerebrovascular disease and dementia were 28.20%,6.70%,15.39%,12.46% and 4.10% respectively in the southern border regions of Xinjiang.Except hypertension,the prevalence rate of other cardiovascular and cerebrovascular diseases in Uygurs and hans had significant differences.The survey found that the prevalence rate of dyslipidemia and diabetes in Hans was higher than the Uygurs,while the Uygurs prevalence rate of cerebrovascular disease and dementia.Conclusion The Xinjiang Uygur and Han elderly are faced with a grim situation of cardiovascular and cerebrovascular diseases;there are significant differences for the nationality and gender.

0.05).[Conclusion]Elbow with fork-like arthroplasty gives good and excellent outcomes in most elbows with different diseases and can provide satisfactory improvement in elbow function for deseased elbows.

0.05).No sign of aseptic loosening or change in implant position was noted.[Conclusion]This short-term study showed that bipolar femoral head arthroplasty seems to be a suitable alternative for primary treatment of displaced femoral neck fractures in patients over 80 years.More attention should be paid to coexisting medical illness(e.g.diabetes mellitus,hypertension,and ischaemic heart disease)and prevention of complications.

[Objective]To explore displacement and plantar pressure distribution of the forefoot before and after the plantar fascia and other plantar ligaments were sectioned.[Method]Seven fresh adult cadaveric feet were tested with the main plantar ligaments exposed,including the plantar fascia,spring ligament,short plantar ligament and long plantar ligament.The displacements of the metatarsals were recorded and calculated with digital speckle correlation measurement(DSCM),also F-scan insoles were put under the plantar aspect of the feet when the speciments were loaded to 700N vertically.The special shifts and plantar pressure data of the metatarsals was collected and stored before and after the main plantar ligaments were sectioned.[Result]The transverse movements of the metatarsals did not change significantly,the same as their vertical displacements except the first metatarsal after the plantar fascia was sectioned,while the peak pressure shifted laterally.When the four major plantar ligaments were all injured,all of the above changed significantly.[Conclusion]The plantar fasciotomy will not consequentially lead to collapse of the forefoot structure.But the redistribution of the plantar pressure and the compensation of other ligaments may result in later complication.
