Objective To investigate the diagnostic values of tumor M2-PK in lung cancer.Methods The concentration of Tumor M2-PK in plasma was detected by ELISA in 106 health controls,77 benign lung disease patients and 92 lung cancer patients.Results TuM2-PK concentration in plasma and the positive rate were singificantly higher in lung cancer(22.1 U/m1,71%)than that in benign lung disease and in health controls(10.5 U/ml,4% and 8 U/ml,3%)(P

Objective:To investigate the effects of survivin antisense oligonucleotide (ASODN) on expression of survivin and ACC-M cell apoptosis. Methods: A phosphorothioate antisense oligonucleotide (ASODN) of specific target survivin was designed and synthesized and then transferred to ACC-M cell line by lipofectin. At the same time blank control group, sense oligonucleotide (SODN) group were set up for comparison. MTT assay was used to detect cytotoxicity. Apoptosis was observed by flow cytometry. Survivin expression was determined by RT-PCR and Western-Blotting. Results: Compared with control group and SOND group, in ASODN groups, the expression of survivin mRNA and protein were obviously weak, apoptosis rate apparently increased, cells growth was inhibited. There was no obviously difference in SODN and control groups.Conclusion:ASODN can down-regulate the expression of survivin gene in ACC-M cell line specifically. It plays an important role in inducing tumor apoptosis and suppressing cell proliferation.

Objective To investigate the impact of metabolic syndrome(MS)on clinicopathology of IgA nephropathy(IgAN). Methods A total of 118 IgAN patients complicated with MS were enrolled in the study as IgAN-MS group. Then 118 IgAN patients of same age arrange without MS were randomly selected as IgAN-non-MS group.A comparative analysis of clinical and pathological data between these two groups was performed. Results The urine protein, serum creatinine, body mass index, mean arterial pressure, serum triglyceride, fasting blood glucose and serum uric acid in IgAN-MS group were all significantly higher than those in IgAN-non-MS group(P<0.05 or P<0.01). The serum HDL-C level in IgAN-MS group was significantly lower than that in IgAN-non-MS group(P<0.01). The percentages of patient with hypertension, abnormal glucose metabolism or abnormal lipid metabolism in IgAN-MS group were also significantly higher than those in IgAN-non-MS group(P <0.01). The glomerular and tubulointerstitial pathological changes in IgAN-MS group were significantly more severe than those in IgAN-non-MS group(P<0.01). There were significantly positive correlations between MS and urinary protein quantity, serum creatinine level, and glomerular damage index or tubulointerstitial damage index(P<0.01)by Spearman rank correlation analysis. Conclusion MS may be an important risk factor of IgAN progression.

Objective To investigate the therapeutic effects of human parathyroid hormone related protein (PTHrP1-34) on osteoporosis of ovariectomized osteoporotic rats. Methods Sixty 4-month-old female Wislar rats were involved in this study and 40 of them were ovariectomized and another 20 received sham operation. After 6 weeks of ovariectomy the osteoporosis model was confirmed by examing 10 ovariectomized and sham-operated rats. The 30 osteoporotic rats were randomly divided into 3 treatment groups, i.e. PTHrP, estradiol and placebo. Human 40 ?g/kg PTHrP1-34 was subcutaneously injected once daily to PTHrP group and the estradiol group was injected with 40 ?g/kg estradiol benzoate once every 3 days.The placebo and shamoperated rats were given 0.2 ml saline every 3 days. The bone mineral density (BMD), bone histomorphology, the bone weight of dry and ash and serum Ca,P,alkaline phosphatase (ALP) were measured after 3 months' therapy. Results After 6 weeks of ovariectomy, the lumbar BMD of ovariectomized rats were significantly declined compared with those of the sham-operated rats. After 12 weeks treatment the femoral and lumbar BMD and the rate of bone weight of dry and ash in the PTHrP group were increased obviously compared with those of placebo groups.There was no significant difference between PTHrP group and estradiol group, in PTHrP group the percent age of trabecular area,trabecular width,osteoblast surface and mineral apposition rate were obviously higher than those in placebo group.Conclusion Treatment with 40 ?g/kg dose of hPTHrP1-34 administered once daily is effective in treating ovariectomy-induced osteoporosis.

Objective To explore the method of obtaining and expanding epithelial stem cells(ESCs) from plucked hair follicle in vitro and clarify that fibroblasts are necessary for ESCs growth.Methods A amount of ESCs from plucked hair were obtained,the epithelial outgrowth of human plucked hair follicle was studied and compared between different culture conditions including no coating well,rat tail-collagen coating well,collagen Ⅳ coating well and 3T3 fibroblasts feeder.The characteristics of these cells were detected by RT-PCR and immunofluorescent staining for CK15.Results After compared between different culture conditions including no coating well,rat tail-collagen coating well,collagen Ⅳ coating well and 3T3 fibroblasts feeder,the results indicated that the plucked hair fragment B3(bulge area of hair follicle) placing on 3T3 fibroblasts feeder was the optimum condition.RT-PCR and immunofluorescent method confirmed that these cells expressed CK15 which was the special marker of ESCs.Conclusion ESCs can be obtained from bulge area of hair follicle which grows on the 3T3 fibroblasts feeder and this method is the optimum condition for ESCs growth after compared between different conditions.

Objective To develop a new methodology of prenatal sonography scoring to assess and dignose clubfoot.Methods Thirty-one fetuses suspected clubfoot(50 foots) and 62 normal fetuses(124 foots) were scanned with both 2D and 3D sonography,and were divided into normal feet group and clubfeet group.Our scoring system was made according to the Pirani-scoring for children,while considering the morphology of mid-foot and hind-foot of infants.The doctors would give final diagnosis for all fetuses after delivery or induced labor,and analyse the correlations among the abnormal signs,sonographic score and the clinical outcomes.Results The curve lat border,the medial crease,the empty heel and the post crease can be observed in the 3D reconstruction images.These four abnormal signs had close correlations with the clinical results.Conclusions The new prenatal clubfeet scoring system by 3D sonography is a promising methodology with clinical values.
