Objective To observe curative effect of mental therapy on women perimenopausal period syndrome.Methods 100 patients with perimenopausal period syndrome were randomly divided into the treatment group and control group with 50 cases in each group. Patients of the treatment group were treated by Cryzanolam, Surazepam, etc,and mental therapy was given simultaneously twice one week. Patients of the control group were treated only by drugs. The period of treatment was four weeks. The curative effect was assessed by SCL-90 symptom self evaluation scales.Results Several factors and total average points of two groups' SCL-90 all dropped, and there was significant difference between two groups after therapy (P<0.01). For patients of the treatment group, clinic symptoms were markedly abated after treatment (P<0.05), and average scores of several factors were not significantly different from normal adults (P>0.05). Conclusion The mental therapy can remit symptoms of women perimenopausal period syndrome effectively and improve their healthy.

Objective To evaluate the value of quantitative 3T dynamic contrast enhanced MRI in the diagnosis of breast lesions. Methods One-hundred and eighteen patients suspected of breast lesions underwent MRI examination. A 3.0 T MR scanner was used to obtain the quantitative MR pharmacokinetic parameters: Ktrans( volume transfer constant), Kep (exchange rate constant) and Ve (extravascular extracellular volume fraction). The mean Ktrans, Kep and Ve of malignant, benign and normal glandular tissues were calculated and compared each other using LSD method. Independent sample t test was used between invasive ductal carcinoma and ductal carcinoma in situ (microinvasion included). Finally, the areas under the ROC curve (AUC) of Ktrans, Kep and Ve between malignant and benign lesions were compared. Results The mean Ktrans, Kep and Ve of malignant lesions (n=87) were (1.010±0.580) min-1, (1.634 ± 1.481) min-1 and (0.735 ±0.273); the mean Ktrans, Kep and Ve of benign lesions (n=23) were (0.331±0.192) min - 1, (0.417±0.324) min - 1 and (0.847±0.291); and the mean Ktrans, Kep and Ve of normal glandular tissues (n =83) were (0.051 ±0.028) min-1, (0.133±0.125) min-1 and (0.597±0.354), respectively. There were significant differences between normal glandular tissues and benign lesions, normal glandular tissues and malignant lesions, benign and malignant lesions in Ktrans (t=9.681, 11.189, 5. 590, respectively, P ＜ 0. 01 ), normal glandular tissues and malignant lesions, benign and malignant lesions in Kep(t =5. 287, 3. 874, P＜0. 05). There were a statistic differences between normal glandular tissues and benign lesions, normal glandular tissues and malignant lesions in Ve(t =2. 932, 2. 562 ,P ＜0. 05). There were no significant differences between normal glandular tissues and benign lesions in Kep, benign and malignant lesions in Ve ( t = 0. 760, 0. 832, P ＞ 0.05 ),invasive ductal carcinoma and ductal carcinoma in situ (microinvasion included) in Ktrans, Kep and Ve(t =0.834,0.075,0.454,P＞0.05). The areas under the ROC curve (AUC) of Ktrans, Kep and Ve between malignant and benign lesions were 0. 934, 0. 941 and 0. 659. The sensitivity of Ktrans, Kep and Ve were 77.01% ,91.95% ,56. 32% and the specificity of Ktrans, Kep and Ve were 95. 65%, 86. 96%, 78.26% for the differential diagnosis of breast lesions if taken the maximum Youden's index as cut-off. Conclusion The differential diagnosis of benign and malignant breast lesions by Ktrans, Kep is applicable.

OBJECTIVETo explore the association of 8-hydroxyguanine glycosidase OGG1 Ser326Cys polymorphism with semen quality and the risk of male infertility.

METHODSThis case-control study included 620 idiopathic infertile patients and 385 normal fertile controls. We determined their genotypes by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and analyzed their semen quality by computer-aided semen analysis (CASA).

RESULTSThe individuals with OGG1 326 Cys/Cys showed significantly lower sperm motility and concentration ([52.1 +/- 26.7]% and (3.75 +/- 0.91) x 10(6)/ml, ln transformed value) than the Ser/Ser carriers ([59.0 +/- 21.8] % and (4.12 +/- 0.88) x 10(6)/ml, ln transformed value) (P < 0.05). The risk of male infertility increased 69% in the OGG1 326Cys allele carriers as compared with the Ser carriers (OR = 1.69, 95% CI: 1.24 -2.31).

CONCLUSIONOGG1 326 Ser/Cys polymorphism might contribute to the risk of male infertility in the southern Chinese population.

OBJECTIVETo investigate retinoblastoma (Rb) associated protein 46 (RbAp46) gene expression levels in bone marrow (BM) cells of leukemia patients.

METHODSReal-time quantitative reverse polymerase chain reaction (QRT-PCR) method was used for detecting RbAp46 expression levels in BM cells of 140 patients with acute leukemia (AL), 13 with chronic myelogenous leukemia in chronic phase (CML-CP), 7 with CML in blast crisis (CML-BC) and 32 with non-leukemic disorders.

RESULTSThe M-Estimators of RbAp46 were higher in 98 newly diagnosed ALs and 5 relapsed ALs than in 28 ALs in complete remission (CR) and 32 non-leukemic controls (178.23 and 213.65 vs 85.89 and 88.08, respectively). No statistic difference was found between the CR group and control group, or between the newly diagnosed group and relapsed group. The M-Estimators of RbAp46 in patients with CML-CP was 58.27, similar to that in control, but much lower than that in CML-BC (173.24). Among 98 newly diagnosed ALs, the M-Estimators of RbAp46 in M(3) and M(4) were the lowest in all of the subtypes. Furthermore, the RbAp46 expression levels were not correlated with the expression of the fusion genes of bcr/abl, PML-RARalpha, and multidrug resistant gene (mdr1), but were positively correlated with Wilms' tumor gene (WT1) expression levels and negatively with AML1/ETO fusion gene expression.

CONCLUSIONRbAp46 expression levels in ALs and CML-BC were strikingly higher than that in non-leukemias and CML-CP, and might participate in leukemogenesis.

Objective To evaluate the feasibility of sentinel lymph node(SLN) mapping with CT lymphography (CT-LG). Methods Twenty-five patients with confirmed breast cancer and no palpably axillary lymph node underwent CT-LG examination. The first one or more lymph nodes along the lymph duct draining from the injection sites to axilla were defined as SLNs, and then the LG results were compared with sentinel lymph node biopsy (SLNB). The over- and underestimation of LG were evaluated. The quality of LG imaging was classified Grade Ⅰ and Ⅱ according to lymph duct appearance on volume rendering (VR). The body mass index (BMI) ＞ 25 was considered obesity. Fisher exact test was used for the statistics. Results (1)Of 25 patients, 5 had local mastectomy history. BMI ＜ 25 was found in 20 cases, and ≥25 was in 5 cases. (2) All SLNs were showed by CT-LG, and Grade Ⅰ and Ⅱ imaging quality were achieved in 21 cases ( 84. 0% ) and 4 cases ( 16. 0% ), respectively. The obese patient tended to have a poor imaging quality ( P ＜ 0. 05 ). (3) Fifty-six SLNs and 45 lymph ducts in all 25 patients were identified on CT-LG. Compared with the results of SLNB, 7 cases ( 28. 0% ) and 9 cases ( 36. 0% ) were over- and underestimated respectively by CT-LG due to obesity and local mastectomy ( P ＜ 0. 05 ). (4) Fifty-two negative SLNs in 18 patients and 15 positive SLNs in 7 patients were confirmed by pathology through SLNB, while 56 SLNs were delineated on CT-LG with 43 negative and 13 positive. The shape in 32. 6% of the negative SLNs (14/43) and 76. 9% of the positive SLNs (10/13) was round,the difference was significant (P＜0. 05). The filling defect on the center in 9.3% of negative SLNs (4/43) and 23. 1% of positive SLNs (3/13) was demonstrated, and irregular filling defect on the margin was found only in 30.8% of positive SLNs (4/13). 3 SLNs in 2 patients combined with small satellite lymph nodes on CT-LG were also confirmed to have tumor infiltration. Conclusion CT-LG can clearly demonstrate the breast lymphatic pathway and may potentially be used for breast SLN mapping, while the imaging quality can be influenced by the obesity and local mastectomy.

Objective To investigate the expression and clinical significance of platelet activating factor [PAC]-1, CD62P and TPP hi severe sepsis. Method Patients with severe sepsis who were admitted into the EICU of Subei People's Hospital from April 2007 to March 2008 were included. Patients with severe sepsis (Group Ⅲ)were treated according to the treatment guidelines for severe sepsis, and were divided, according to their clinical records, into those who survived and those who died within 28 days of admission. Patients admitted during the same period with symptoms of infection but without severe sepsis were included as the General Infected Group (Group Ⅱ). A Control Group (Group Ⅰ) comprised patients who visited the hospital over the same period for physical examination or the healthy volunteers. The group members were all included randomly, and the gender and sex of patients in all three groups were similar. Patients with acute brain infarction, acute coronary syndrome,serious diabetes, hyperlipidemia, malignant tumor, leukemia, primary liver, renal and hematopoietic system dis-eases,long-term bedridden patients, pregnant women, and patients taking hormone treatment or hranunosuppres-sants were excluded from the study. Morning venous blood was collected and ELISA and Flow Cytometry performed on the fwst day of admission for Groups Ⅰ- and Ⅱ, and on the first, third and fifth day after admission for Group Ⅲ, to determine the TpP,PAC-1 and CD62P respectively; and the Marshall score was determined. Data were ana-lyzed by SPSS 12.0 software. For continuous variables, comparisons among groups were analyzed by ANOVA.Levene's and LSD test were applied to assess homogeneity. Bivariate test is applied to Correlation Analysis. P<0.05 was regarded as a statistically significant difference. Results There were a total of 20 patients each in GroupⅠ-and GroupⅡ, and 30 in Group Ⅲ; of these, 19 were classed as survivors and 11 died during the 28-day peri-od. On the first day of admission, there were no significant differences in PAC-1, CD62P or TpP expression between Groups Ⅰ- and Ⅱ(P>0.05); however, Group Ⅲ was significantly different compared with both Group Ⅰ and Group Ⅱ (both:P<0.05). The expression of PAC-1, CD62P and TpP tended to decline in the survivor group,and became normal with the treatment process, while the expression of PAC-1 ,CD62P and TpP in the patients who died remained high, and even increased significantly over time. On the first day, the expression of CD62P and TpP in the patients who survived and in those who died was not significantly different (P>0.05); on the third day,however, a significant difference appeared with values of (2.89±1.48) % vs. (5.04±2.57) % (P<0.01) for CD62P, and (5.24±2.22) mg/L vs. (9.20±1.93) mg/L (P<0.01) for TpP. The expression of PAC-1 was significantly different between the two subgroups on the first day, with values of (3.15±0.42)% vs. (5.30±.48)% (P<0.01). The Marshall score of the two groups showed similar changes. Correlation analysis showed that PAC-1, CD62P and TpP were significantly correlated with the Marshall score. Conclusions Platelet activation and microthrombosis existing in the early stage of severe sepsis work together in the early hypercoagulable state.They both play important roles in disease development and progression. The dynamic detection of CD62P and TpP is beneficial to the diagnosis and prognosis of severe sepsis.PAC-1 appears to hold a risk stratification effect, as pa-tients with high expression of PAC-1 in the early stage show poor prognosis. Therefore, PAC-1 could be used as a marker of severe sepsis and poor prognsis.

Objective To evaluate the diagnostic values of the breast imaging reporting and data system-MRI (BI-RADS-MRI)description about non-masslike enhancement by data mining. Methods Fifty-five patients with non-masslike enhancement lesions showed on breast contrast-enhanced MRI were evaluated using two data mining algorithms (Logistic regression and decision tree) and 10-fold cross-validation methods. Results There were 28 malignant and 27 benign lesions. The most frequent findings of the malignant lesions were clustered ring enhancement and clumped enhancement [ 12 and 4 lesions, respectively; 84. 2% (16/19) in decision trees, partial regression coefficients in Logistic model were 2. 128 and 1.723, respectively], whereas homogenous, stippled, reticular internal and linear ductal enhancement were the most frequent findings in benign lesions [ 4、9、1 and 7 lesions, respectively; 72. 4% (21/29) in decision tree, partial regression coefficients in Logistic model were 0.357 (homogenous), 1. 861 (stippled) and 18. 870( reticular), respectively]. 10-fold cross-validation indicated that decision tree (C5.0) achieved an accuracy of 69.3% with a sensitivity of 66.7% and a specificity of 71.7% in comparison to the Logistic regression model with an accuracy of 57. 0%, a sensitivity of 43.3% and a specificity of 71.7%. Conclusions The diagnosis efficacy of non-masslike enhancement interpretation according to BI-RADS-MRI is not high. It is very important to find more potential features of non-masslike enhancement to improve the diagnosis accuracy.

BACKGROUNDIntervertebral disc degeneration is the main cause of low back pain. The purpose of this study was to explore potential methods for reversing the degeneration of lumbar intervertebral discs by transplantation of gene-modified nucleus pulposus cells into rabbit degenerative lumbar intervertebral discs after transfecting rabbit nucleus pulposus cells with adeno-associated virus 2 (AAV2)-mediated connective tissue growth factor (CTGF) and tissue inhibitor of metalloproteinases 1 (TIMP1) genes in vitro.

METHODSComputer tomography (CT)-guided percutaneous annulus fibrosus injury was performed to build degenerative lumbar intervertebral disc models in 60 New Zealand white rabbits. rAAV2-CTGF-IRES-TIMP1-transfected rabbit nucleus pulposus cells were transplanted into degenerative lumbar intervertebral discs (transplantation group), phosphate-buffered saline (PBS) was injected into degenerative lumbar intervertebral discs (degeneration control group) and normal lumbar intervertebral discs served as a blank control group. After 6, 10 and 14 weeks, the disc height index (DHI) and signal intensity in intervertebral discs were observed by X-ray and magnetic resonance imaging (MRI) analysis. The expression of CTGF and TIMP1 in nucleus pulposus tissue was determined by Western blotting analysis, the synthesis efficiency of proteoglycan was determined by a (35)S-sulfate incorporation assay, and the mRNA expression of type II collagen and proteoglycan was detected by RT-PCR.

RESULTSMRI confirmed that degenerative intervertebral discs appeared two weeks after percutaneous puncture. Transgenic nucleus pulposus cell transplantation could retard the rapid deterioration of the DHI. MRI indicated that degenerative intervertebral discs were relieved in the transplantation group compared with the degeneration control group. The expression of collagen II mRNA and proteoglycan mRNA was significantly higher in the transplantation group and the blank control group compared with the degeneration control group (P < 0.05).

CONCLUSIONSCT-guided percutaneous puncture can successfully build rabbit degenerative intervertebral disc models. Both CTGF and TIMP1-transfected cell transplantation helps to maintain disc height, and promotes the biosynthesis of type II collagen and proteoglycan in intervertebral discs, reversing the degeneration of intervertebral discs.
