Six patients with ST segment elevated acute myocardial infarction (AMI), who were 52.5 years old in average, were enrolled and performed the treatment at Tongren Hospital from November 2003 to June 2004. Following percutanecus transluminal coronary angioplasty and stent revascularization, autologous bone marrow stem cell (BMSC) transplantation was performed after informed consent was obtained. Patients were subcutaneously injected with granulocyte colony-stimulating factor (G-CSF) at 1 week before transplantation. When CD34+ cells going up to 1%-3% in peripheral blood, mononuclear cells in peripheral blood were harvested,purified, and further infused into the infarcted related coronary artery with an over-the-wire balloon catheter. Following up was performed every half a year. Four years later, the infarcted area of these patients was further decreased by 8.03%, in the basic descent of 42.7% at 3 months averagely; total infracted area descent was 50.73%, but ejection fraction increased by 4.6% from 50.8%. There was no serious coronary artery restenosis and/or stenosis formation which need revascularization upon angiography.

Objective To establish a culture protocol for Th17 cells in vitro and evaluate the effect of curcumin on the differentiation and functions of Th17 cells and explore the related mechanisms. Methods Splenic CD4+CD25- T cells of C57BL/6 mice were isolated and purified with magnetic bead methods, and were co-cultured with plate-bound anti-CD3 and anti-CD28 antibodies and with transforming growth factor (TGF)-β, interleukin (IL)-6, IL-23, anti-interferon-γ antibody and anti-IL-2 antibody for Th17-polarization. The cultured Th17 cells were allocated into four groups: the control group, in which T cells were cultured on the basis of the above protocol; the low-concentration curcumin (CM-L, 5 μmol/L) and high-concentration (CM-H, 25 μmol/L) curcumin groups, and sirolimus (SRL, 100 ng/ml) group. The proportion of Th17 cells was detected with flow cytometry, and the mRNA expression of retinoic acid-related orphan receptor (ROR)γt, IL-17A, IL-21 was examined with real-time quantitative polymerase chain reaction. Finally, the protein expression of RORγt and the phosphorylation levels of signal transducer and activator of transcription (STAT) 3 were measured using western blotting analysis. Results The proportion of Th17 cells in the freshly isolated CD4+CD25- T cells was (3.1 ±0.4)%, whereas the proportion of the cells cultured with the protocol could get [(54.1±3.4)%, P<0.01]. As compared with the control group, the Th17 cells proportion in CM-L, CM-H and SRL groups was significantly decreased [CM-L (40.3±2.8)%, CM-H (25.8±2.3)%, SRL (25.0±2.0)%versus the control (54.1±3.4)%, t=6.15, 12.63, 12.97, P<0.01], and no marked difference was seen between CM-H group and SRL group (ft>0.05). Moreover, the mRNA levels of RORγt, IL-17A and IL-21, the protein expression of RORγt and the phosphorylation levels of STAT 3 in CM-L, CM-H and SRL groups were also lower than those in the control group (IL-17A mRNA: CM-L 0.81±0.05, CM-H 0.61±0.05, SRL 0.58±0.05, Control 1.01 ±0.11, t=4.81, 8.52, 8.89; IL-21 mRNA: CM-L 0.73±0.06, CM-H 0.49±0.03,SRL 0.59±0.03, Control 1.12±0.11, t=5.98, 9.22, 7.95, P<0.01). The mRNA level of IL-21 in the CM-H group was lower than that in the SRL group (P<0.05). Conclusion In vitro, curcumin can inhibit the differentiaton of splenic CD4+CD25- T cells into Th17 cells in the setting of Th 17-polarization and inhibit the expression of IL-17A and IL-21 mRNA, which is associated with the inhibitive effect of curcumin on RORγt expression and STAT 3 phosphorylation.

Objective To observe the outcomes of toe amputations in diabetic patients and to analyze the affecting factors.Methods Two-hundred and forty-five patients were divided into 2 groups:202 cases with the wound healed after toe amputation,and 43 patients whose wound did not heal after toe amputation.The factors related to healing were analyzed.Patients with healed wounds after toe amputations ( n =202 ) were followed,regarding reappearance of new ulcers,reamputations,mortality,activities of daily life,and the affecting factors.Results The rate of wound healing was 82.4％.The rate of follow-up in the healed group was 91.6％.The rates of reappearance of new ulcers after 1,3,and 5 years of observation were 27.3％,57.2％,76.4％,respectively.The rates of reamputations after 1,3,and 5 years of observation were 17.5％,22.3％,47.1％,respectively.The mortality rates by 1,3,and 5 years after the toe amputations were 3.8％,15.1％,32.7％,respectively.Mean survival time of the fatal cases after the first amputation was 3.8 (95％ CI 3.4-4.1 )years.Multivariate analysis showed that HbA1c (＞9％)was an independent predictor of wound healing,reappearance of new ulcers,and reamputations after toe amputations,and age ( ＞ 70 years ) was an independent predictor of reamputations,mortality,and hampered daily activities.Conclusion Despite a satisfactory initial healing process after the first amputation,the long-term outcomes of the followed-up patients are not optimistic.Senile patients are often with poor prognosis,and good blood glucose control may improve the prognosis.

Objective To study the expression difference of the insulin-like growth factor-I (IGF-I)and IGF-binding proteins-3,4,5(IGFBP-3,4,5)in the peripheral and local areas in senile hip fracture and discuss the correlation between the expression and the fracture types. Methods The study involved the senile patients (over 65 years) with hip fractures to compare the expressions of peripheral and local IGF-I and IGFBP-3,4,5 and observe the correlation between expression and fracture type.Results The serum and local specimens of 46 patients were collected,with lower level of BMD,IGF-I and IGFBP-3,5 in the intertrochanteric fracture group than the femoral neck fracture group(P<0.001)and with higher level of serum and local IGFBP-4 in the intertrochanteric fracture group than the femoral neck fracture group (P<0.001).Only local IGFBP-4 mRNA had positive correlation with serum markers (R=0.544,P<0.001). Conclusions The expression difference of IGF-I and IGFBP in the peripheral and local serum may be one of pathogenesis leading to different types of hip fractures.Except for the IGFBP-4,the other factors may affect the bone metabolism of the senile hip fractures through different regulatory mechanisms.

Objective To study etiology screening role of transrectal ultrasonography in male obstructive azoospermia infertility.Methods The clinical data of 328 cases who suspected of being obstructed sperm disease were retrospectively analyzed.TRUS detection was conducted,at the same time,the sperm amount,sperm and semen pH,pure berries quantitative,neutral sugar alpha glycosidase enzymes quantitative,elastic hard protease were tested.Results In 328 cases with male obstructed no sperm,by TRUS detection results,216 cases (65.8％) could find the causes,ejaculatory duct expansion,seminal vesicle gland lesions,prostate midline cyst were the top three causes respectively;112 patients(34.2％) had no obvious abnormal ultrasonic testing.Sperm was not seen in semen of obstructive azoospermia patients and semen pH ＜ 7,pure berries sugar quantitative and quantitative value neutral alpha glycosidase enzymes were very low,hard elastic protease was low.Conclusion The main causes of obstructive azoospermia were ejaculatory duct expansion,seminal vesicle gland lesions,prostate midline cyst,sperm TRUS detection used for diagnosis of high sensitivity,and easy to operate,noninvasive,and combined with seminal plasma biochemical examination,the diagnostic effect is much better.

Objective To investigate functional role and clinical significance of the methylation in the promoter of TPAP gene in the development and progression of pancreatic cancer.Methods Surgically resected specimen from 68 patients who were pathologically diagnosed as pancreatic cancer in Changhai Hospital from July 2006 to August 2009 were collected.The methylation in the promoter of TPAP gene in tumor and nontumor adjacent tissue was detected by methylation specific PCR.Results The methylation rate of tumor and non-tumor adjacent tissue was (0.214 ± 0.057) ％ and (0.084 ± 0.096) ％,respectively,and pancreatic cancer tissue had significantly higher methylation rate than the adjacent tissue.Hypermethylation of TPAP gene was not correlated with age,gender,tumor differentiation,lymphatic metastasis,serum CEA and CA19-9,but was positively correlated with distant metastasis.Conclusions Hypermethylation in the promoter of TPAP gene may participate in the invasion and metastasis of pancreatic cancer and the hypermethylation of the promoter is closely associated with the tumorigenesis and development of pancreatic cancer.

Objective To evaluate the effects of assisted reproduction technology ( ART) on gestational weight gain ( GWG) and glucose metabolism .Methods The study was performed in ART women with single-ton and full-term delivery .Age-and pre-pregnancy body mass index matched healthy women with spontaneous pregnancy, singleton, and full-term delivery were recruited as controls .Maternal characteristics (height, age, education level , pre-pregnancy body mass , pre-delivery body mass , medical history , history of abortion , fasting plasma glucose , triglyceride , total cholesterol , and glucose tolerance ) and fetal data ( delivery mode , gender , birth body mass , birth body length ) were collected by a trained nutritionist .Results A total of 200 women were recruited into this study (53 ART women and 147 controls).There was no significant difference in number of previous abortion ( the ratio between the women who had ≥3 abortions to those who had <3 abortions was 6∶47 in the ART group , and 10∶137 in the control group , χ2 =1.080 , P=0.299 ) .Compared with the control group, the ART group had higher education level (33 in the ART and 85 in the control group with un-dergraduate or higher education , 20 in the ART group and 62 in the control group with a college degree or lower education ,χ2 =6.303 , P=0.012 ) .There were no statistically significantly differences between the ART and the control groups in pre-pregnancy body mass index [ (22.00 ±3.05 ) kg/m2 vs.(21.81 ±2.62 ) kg/m2 , P=0.661] and average GWG [ (13.89 ±5.33) kg vs.(14.78 ±4.60) kg, P=0.247].GWG was appro-priate in 22 ART women, excess in 18, and inadequate in 13;in the control group, GWG was appropriate in 66 women, excess in 54, and inadequate in 27.The distribution of GWG showed no significant difference be-tween the two groups (χ2 =1.162 , P=0.247 ) .Oral glucose tolerance test in 24-28 gestational weeks showed no significant difference in fasting blood glucose between the ART and the control groups [ (4.66 ±0.39) mmol/L vs.(4.66 ±0.52) mmol/L, P=0.996], but 1-hour and 2-hour blood glucose levels were significantly in-creased in the ART women [ ( 7.87 ±1.83 ) mmol/L vs.( 7.31 ±1.51 ) mmol/L, P=0.034; ( 7.49 ± 1.29) mmol/L vs.(6.69 ±1.30) mmol/L, P=0.029].The overall prevalence of gestational diabetes melli-tus was 13.5%(27/200), with no significant difference between the ART and the control groups (18.9%vs. 11.6%, P=0.182 ) .Conclusion ART may not affect GWG , but it may cause changes of glucose metabo-lism during pregnancy .

Objective To investigate the effect of curcumin on autophagy and inflammatory response in mice subject to renal ischemia reperfusion.Method Forty male C57BL/6 mice were randomly divided into four groups (n =10 each):sham-operated (SO) group (Abdominal incision was made to expose the kidneys,bilateral renal pedicle dissociated and the abdomen sewed),ischemia reperfusion (IR) group,curcumin (CM) group (given CM 10 mg/kg) and 3-methyladenine (3-MA) group (given 3-MA 15 mg/kg).Six and 24 h after reperfusion,renal function was tested by determining the serum creatinine (Scr) and blood urea nitrogen (BUN) levels,and the morphological changes in the kidney tissue were observed.The expression of LC3,Beclin 1,Rab7 and LAMP2 in kidney tissue was detected by fluorescence quantitative RT-PCR and Western blotting.Fluorescence quantitative reverse transcription PCR and enzyme-linked immunosorbent assay were used to examine the expression of IL-6,IL-10,IL-17 and TNF-α in kidney tissue and serum.Result As compared with IR group and 3-MA group,the Scr and BUN levels in the CM group were significantly decreased (P＜0.01),and the renal morphological changes were improved significantly (P＜0.01).The mRNA and protein expression of LC3,Beclin 1,Rab7 and LAMP2 was significantly increased in kidney tissue,and the expression of IL-6,IL-17 and TNF-α was reduced,while IL-10 was increased (P＜ 0.01) in the CM group as compared with IR group and 3-MA group.Conclusion Curcumin possesses a protective effect against renal ischemia reperfusion injury in mice,which is probably mediated by promoting autophagy and subsequently inhibiting inflammatory response.
