Objective To investigate the diagnostic value of 1H magnetic resonance spectroscopy (1H-MRS) in mammary tumors and to discuss the technique factors which influence the detection rate.Methods The 1H-MRS features of 47 mammary tumors, of which 24 malignant tumors and 23 benign tumors confirmed by pathology were analyzed. All of the tumors were detected before Gd-DTPA enhancement. Results Eleven of 24 malignant tumors showed increased choline resonance peak at 3.24 ppm while 4 of 23 benign ones at 3.24 ppm .The positive value were 45.8% and 17.4% respectively. The sensitivity and specificity were 45.8% and 82.6% respectively by using 1H-MRS to discriminate benign from malignant tumors. The main factors influencing the detection rate were low suppressed lipid, low suppressed water and low single-noise rate.Conclusion Choline is not special features of malignant tumors. Choline can be obtained despite the nature of tumor if they grow rapidly. The low sensitivity of choline to be detected mainly dues to technique factors.

Objective To investigate the relationship between single nucleotide polymorphism (677C→T) of methylenetetrahydrofolate reductase and Alzheimer′s disease(AD) in south China Han people. Methods By applying polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP), MTHFR 677C→T mutation was detected in 45 AD patients and 48 healthy controls. Results The frequency of MTHFR 677C→T mutation of patients showed no significant difference to that of healthy controls (P > 0.05). There is no statistic significance between AD group and controls in C, T gene frequency(P>0.05). But T gene frequency is higher in AD group than in control group. Conclusion MTHFR C 677T is not the pathogenic factor for AD, but could have some effects on AD.

Objective To incubate the rat neural stem cells with specific inhibitor (PD98059) of MAPKK/MEK to clarify the effect of MAPKK/MEK-MAPK/ERK signaling pathway in neural stem cells (NSC).Methods NSCs derived fiom E15-16 rats were isolated and cultured.After treated with different concentration of PD98059,they were subjected to the detection of cell proliferation,Nesn'n, BrdU and β-tubulin-Ⅲ by WTS-8 assay,immunofluorescent staining or Western Blot respectively.Results PD98059 had an effect on the survival,proliferation and differentiation of NSC at a concentration-dependent manner.The viability of the NSC was significantly decreased than the control (P＜0.05),whereas the numbers of BrdU-positive and β-tubulin-Ⅲ positive cells were notably fewer than the control (P＜0.05) after incubated with the higher concentration of PD98059.The ERK expression was blocked by PD98059 at a concentration-dependent manner.Conclusion The MAPKK/MEK-MAPK/ERK signaling pathway played a vital role in the survival, proliferation and differentiation of NSC.

Objective To investigate the effect of recombinant human growth hormone on the PingPang Racket flap survival.Methods Every two PingPang Racket flaps were designed on the both sides of 40 adult SD rats's back.The pedicle size was 1.0 cm × 1.0 cm,while the flap size was 3.0 cm in diameter circular.Longitudinal axis of flap was perpendicular to the center line of the rats back,to which the distance from proximal pedicle was about 1 cm.The flaps on the left side served as Ⅰ group,and the other side served as Ⅱ group,which were subdivided into Ⅰa and Ⅰb,Ⅱa and Ⅱb,respectively.And there were 20 rats in each subgroup.On the flap surfaces in group Ⅰ,it was 6 uniform injection poinsts,subcutaneously injecting with rhGF (the dose was 0.1IU · Kg-1 · d-1) for 7 days from the beginning of operation,that were designed.It goes the same way to the group Ⅱ,while normal saline was instead of rhGF.In subgroup Ⅰa and Ⅱa,the flaps were generally observed every day.The percentage of the flap survival area was determinated 7 days after operation.In subgroup Ⅰb and Ⅱb,specimens were collected at the distal end of flap at intraoperative(before injecting rhGF)and 1 st,3rd,5th,7th day after operation.Immunohistochemistry and enzyme-linked immunosorbent were applied to examine the expression of TGF-β1 and CD34,and the microvessel density of the flaps was calculated.Results According to the 7 days' observation after the surgery,the flap survival area percentage of subgroup Ⅰa was (97.00 + 2.12) ％,which was significantly higher (P ＜ 0.05) than that of subgroup Ⅱ a,whose was (81.00 +3.43)％.On 1st,3rd,5th and 7th day postoperatively,the expression of TGF-β1,CD34 in both subgroup Ⅰb and Ⅱb were elevated and reached peak on the 5th day.Content of GF-β1 and CD34 in Ⅰb were 1571.40 ± 13.32 pg/ml and 60.40 ±0.32 pg/ml,respectively,and in Ⅱb were 691.43 ± 11.06 pg/ml and 20.43 ± 0.06 pg/ml.At the same point of time,the expression of TGF-β1,CD34 were significant higher in Ⅰb subgroup than that in Ⅱb (P ＜ 0.05).In subgroup Ⅰb and Ⅱb,the number of microvessels increased on postoperative 1 st,3rd,5th and 7th day,especially on 3rd,5th and tended to be stable at 7th day.At the same point of time,the number of microvessels in Ⅰb was always higher than that in Ⅱb (P ＜ 0.05).Conclusion Subcutaneous injection of rhGH on flaps can enhance the expression of TGF-β1,CD34,promote microvascular generation of the flap tissue directly or indirectly,and also improve the survival of PingPang Racket flaps.

Objective: To investigate the effects of low molecular weight heparin(LMWH) on vascular endothelial growth factor(VEGF) expression of early diabetic nephropathy. Methods: Ninety-five male SD rats were randomly divided into three groups: normal control rats, STZ-induced diabetic rats and diabetic rats treated with LMWH. The renal tissues were subjected to immunohistochemical staining after 1,2,4,6,and 8 weeks’ treatment respectively to quantify the VEGF expression. Results: Immunohistochemical staining demonstrated an increasing in VEGF positive cells in diabetic rats. It was found that there were significant differences in VEGF staining intensity between diabetic rats and normal control rats and between LMWH treated rats and untreated diabetic rats after two weeks treatment. Conclusion: The inhibition of VEGF expression may be one of the mechanisms of LMWH’s renal protective effects on early diabetic nephropathy.
