Objective To observe the effects of Sanhuangtangshenkang particles on the expression levels of tumor ne?crosis factor (TNF)-α, interleukin (IL)-6 in bone tissue of type 2 diabetic (T2DM) rat model. Methods There were seven groups of rats in this study. Ten female Wistar rats were used as control. Ten rats were established for osteoporosis model, and fifty rats were established for diabetic model. Fifty diabetic model rats were further divided into model control group, tra?ditional Chinese medicine (TCM) prevention group (high-dose TCM group, low-dose TCM group) and Western medicine group, with 10 rats for each group. All rats were given the corresponding intervention for 20 weeks. Automatic biochemistry analyzer was used to determine fasting blood glucose (FBG). ELISA was used to detect serum TNF-αand IL-6. Dual-energy X-ray absorptiometry (DXA) was used to assess bone density. Real-time PCR was used to appraise the mRNA of TNF-αand IL-6 in bone tissue. Western blot assay was used to measure protein expressions of TNF-αand IL-6 in bone tissue. Re?sults Compared with osteoporosis model group, bone density was significantly increased, serum levels of TNF-αand IL-6, the mRNA and protein expression level of IL-6 were significantly decreased in bone tissue of TCM groups and Western medi?cine group (P<0.05). The expression levels of TNF-αmRNA and protein were significantly decreased in bone tissue of in high-dose TCM prevention group and Western medicine group (P<0.05). Compared with the diabetic model group, the se?rum levels of FBG, TNF-αand IL-6 were significantly decreased in TCM groups and Western medicine group (P<0.05). The expression levels of TNF-αmRNA and protein were significantly decreased in high-dose TCM prevention group and Western medicine group (P<0.05). The mRNA and protein expression levels of IL-6 were significantly decreased in low-dose TCM prevention group and Western medicine group (P<0.05). Conclusion The expression levels of TNF-αand IL-6 are increased in serum and bone tissue of diabetic rats. Sanhuangtangshenkang particles can improve the inflammatorystate to play prevention and therapeutic effect on diabetic rats.

ObjectiveTo investigate the effect of clinical pathway teaching methord in nursing practice teaching. Methods80 junior college nursing students were randomly divided into control and experimental groups. Traditional clinical teaching method was given to control group, while the clinical pathway teaching method was given to observation group. Scores of comprehensive quality after departmental rotation and satisfaction rates of nursing students to teaching method in these two groups were evaluated. ResultsThe experimental group was significantly better than the control group ( P＜0.05 ), and the difference was statistically significant. ConclusionThe clinical pathway can significantly improve the quality of nursing practice teaching.

Objective To investigate the effect of endoplasmic reticulum stress in hyperlipidemia rats with acute pancreatitis(AP).Methods Forty-eight SD rats were divided into AP group(n=18,in- duced by injection of 40?tg/kg caerulein in normal rats twice with 2 hrs interval),normal control(n=6), byperlipidemia group(n=6,fed with a high-fat diet for 8 weeks)and hyperlipidemia AP group(n=18,in- duced by injection of 40?g/kg caerulein in hyperlipidemia rats twice with 2 hrs interval).The rats were sacrificed at 9,12,24 hrs(6 of each),respectively.Serum level of amylase was tested and the pathologi- cal changes of the pancreatic tissues were observed.The index of pancreatic apoptosis was assessed by TUNEL method.The expression of GRP78/Bip(glucose regulated protein)protein was determined by immunochemistry,the endoplasmic reticulum stress related molecules of XBP-1 splicing(X box binding protein),CHOP/GADD153(C/EBP-homologous protein or growth arrest and DNA-damage-inducible gene 153),caspase-12 were analyzed by RT-PCR.The dynamic expressions of GRP78/Bip and caspase- 12 were determine,d by Western blot.Results Artier 8 weeks of fat diet in hyperlipidemia rats,the ser- um levels of triglyceride[(0.99?0.38)mmol/L]and cholesterol[(3.17?0.18)mmol/L] were signifi- cantly increased(P

Objective To investigate the expression of Fas antigen (Fas) and ligand (FasL), placental growth factor (PlGF) in placenta of pregnant women with pre-eclampsia. Methods Expressions of Fas, FasL and PlGF of placenta were determined by immunohistological streptavidin-peroxidase-biotin (SP) method and compared between normal late pregnancy (24 cases) and mild pre-eclampsia (24 cases) and severe pre-eclampsia (24 cases) groups. Results Different expression of levels Fas, FasL and PlGF were observed in the trophoblasts of most placentae. Positive immunostain of Fas, FasL and PlGF was mainly located in the cytoplasm and membrane of syncytiotrophoblast. FasL and PlGF expressions (63?4, 81?6 and 42?6, 65?6) were significantly less (P

Produced by bone cells and stored in the matrix.bone ceil growth factor can contribute to the regulation of bone growth.Gene regulation has its role in bone development.Many factors of this kind have been founded recently.They play their role during the bone formation and absorption processes in the way of autocrine and paracrine.The genes of core binding factor α_1(Cbfα_1)and estrogen receptor α(Erα)have been the recent years'hot factors that are related to the bone development,Gene polymorphism refers to variation on gene level which often occurs in the non-coding domain or the domain bearing no important regulatory function in gene order.This article reviewed the research status of the relation between Cbfα_1 and Erα gene polymorphism with bone development.

Objective To study the clinical value of DTI in the evaluation of high intensity focused ultra-sound (HIFU) for treating uterine fibroids by analyzing the characteristics of DTI before and after surgery. Methods DTI was performed before and after HIFU. The study included 25 patients with 30 uterine fibroids. All data were processed using GE AW4.5 Workstation. ADC,FA,VRA and T2-weighted trace of uterine fibroids before and after HIFU were recorded and analyzed. Results After HIFU,no enhancement was observed in uterine fibroids on DCE-MRI. The signal of uterine fibroids on FA,VRA map was lower after HIFU. No statistical differences were found between ADC and T2-weighted trace before and after the surgery(P>0.05). FA and VRA of uterine fibroids after HIFU were lower than those before the surgery(P<0.05). Conclusion FA and VRA can reflect micro differ-ence of uterine fibroids before and after HIFU ,which is useful for assessing the curative effect after HIFU.

Objective To analyze and compare the imaging characteristics of contrast-enhanced ultrasound (CEUS) and contrast enhanced magnetic resonance imaging (CEMRI) in diagnosing hepatic epithelioid hemangioendothelioma (HEHE) for improving radiological diagnostic accuracy.Methods The imaging characteristics of CEUS and dynamic CEMRI in 17 patients with histopathological diagnosis of HEHE on specimens obtained after surgical resection or fine needle biopsy were retrospectively analyzed and compared.Results On CEUS,20 lesions in 13 patients demonstrated different enhancement patterns in the arterial phase:13 lesions (65.0％) displayed gross enhancement and 7 lesions (35.0％) displayed a rimlike enhancement.Synchronous enhancement was observed in 17 lesions (85.0％) and rapid enhancement was observed in 3 lesions (15.0％).All these 20 lesions manifested as a hypoechoic mass in the portal venous and delayed phases.Other characteristics included speculated enhancement in the inner margin of the lesions and a vessel sign.On CEMRI,45 lesions (71.4％) manifested slight enhancement in the arterial phase and continuous enhancement in the portal venous and delayed phases.The remaining 18 lesions (28.6％) manifested no enhancement in the arterial phase but progressive enhancement in the portal venous and delayed phases.47 lesions (74.6％) displayed a rim-like enhancement and 16 lesions (25.4％) displayed gross enhancement.Other imaging characteristics included a halo sign,a lollipop sign,a capsular retraction sign or avessel sign.Conclusions On CEUS,characteristic manifestations of HEHE were synchronous enhancement with a quick wash-out.At peak time,the enhancement degree was equal to the normal liver parenchyma.On CEMRI,the main radiological feature of HEHE was a rim-like enhancement.In the arterial phase,the enhancement degree was not high and there was either a continuous enhancement or a progressive enhancement in the portal venous and delayed phases.Furthermore,HEHE lesions always occurred under the liver capsule and showed acapsular retraction sign,ahalo sign,a lollipop sign or a vessel sign.The combination of CEUS and CEMRI helped to improve the diagnostic rate and contributed to selection of clinical treatment.
