ObjectiveTo develop a simple scoring system to identify individuals with higher risk of type 2 diabetes mellitus ( T2DM ).Methods Major risk factors of T2DM were fixed after literature review.Logistic regression was used to select risk factors of T2DM.Target populations were randomly assigned to 2 groups,and group A was used for the development of risk factor scoring method and group B for the confirmation of this new method.Results The threshold for T2DM risk was 65.0 for men and 65.5 for women ( sensitivity 90.6％ and 83.3％,respectively; specificity 89.4％ and 97.7％,respectively ; positive predictive value 58.8％and 80.0％,respectively;negative predictive value 98.3％and 98.2％,respectively ; area under the curve 0.955 and 0.899,respectively).There was significant difference of T2DM detection between screening and risk scoring system ( P =0.000 ).Conclusion Our T2DM risk scoring system may provide an effective tool to identify individuals with a higher risk of developing T2DM.

Objective To evaluate the effects on pregnancy outcome of freezing time from oocyte retrieval and thawing method for metaphase Ⅱ human oocytes vitrification. Methods From Mar 2007 to Mar 2009, the clinical outcome of 30 infertile women undergoing vitrified-thawing oocytes of in vitro fertilizationembryo transfer(IVF-ET) in the Reproductive Medical Center of the First Affiliated Hospital of Zhengzhou University was studied retrospectively, including 21 women with double fallopian tube obstruction and 9 women's husband azoospermia. All infertile women were divided into three groups, including 5 cases in group A (freezing between 4 and 5 hours from oocyte retrieval and conventional thawing method), 9 cases in group B (freezing within 2 hours from retrieval and conventional thawing method) and 16 cases in group C (freezing within 2 hours from retrieval and improved thawing method). The vitrified oocytes were preserved for 2 months to I year and thawed for Intracytoplasmic sperm injection (ICSI) and embryo transfer. The outcome of IVF and pregnancy were recorded. Results (1) The rates of oocyte survival was (65±33) % in group B and (72±23)% in group C and the rate of transfer cycle was 9/9 in group B and 16/16 in group C, which were all significantly higher than (16±17) % of oocyte survival and 1/5 of transfer cycle in group A (P = 0. 001,0. 021). However, the rate of oocyte survival and transfer cycle between group B and group C did not reach statistical difference (P > 0. 05). The rate of implantation and clinical pregnancy of (33±38) % and 9/16 in group C were significantly higher (4±11)% and 1/9 in group B (P =0. 033,0. 040).(2)The mean age of women in group C were (28.6±2.1) in oneself oocyte, (28.0±4.6) in donor oocyte and (28.1±3.4) in donor sperm. The rate of oocyte survival was (73±25) %, (88±10) % and (66±25) %. The rate of fertilization rate was (84. 6±0. 9) %, (79. 3±2. 0) % and (82. 8±15.0) %. The rate of implantation was (20. 0±44. 7) %, (33. 0±0. 1) % , (41.6±41.7) %. The rate of clinical pregnancy was 1/5 in oneself cycles,3/3 in donor oocyte cycles, 5/8 banked donor sperm cycles in group C. All above clinical parameters were not statistically different (P >0. 05). (3) In group A, one women underwent IVFET and no clinical pregnancy was observed. One women pregnancy was terminated at two months in group B.The clinical pregnancies rate of group C was 9/16, late abortion occurred in 1 woman, the other 8 women underwent term pregnancy, including 5 male infants and 4 female infants. All of infants showed normal Karyotype. Live-birth rates per warmed oocyte was 5.9% (8/135). The mean gestational weeks and birth weight of the infants were (39. 4±0. 9) weeks and (3574±569) g, respectively. Conclusions Embryo quality and clinical outcome of thawing cycles could be significantly improved when oocyte vitrification was performed within 2 hours from oocyte retrieval and improved thawing method.

Aim To investigate the effect of the total flavonoids of Epimedium (TFE)on MAPK/NF-κB sig-naling pathway and the inflammatory reaction in the hippocampus of natural aging male rats.Methods The morphological changes of the hippocampus com-posed of three areas (CA1 ,CA3 and DG)were ob-served using haematoxylin-eoin (HE ) staining.The protein expression levels of senescence-associated pro-tein p21,apoptosis-related proteins Bax and Bcl-2, nuclear transcription factor-κB p65 (NF-κB p65 )and its downstream inflammatory factors TNF-α,IL-1βand COX-2,and MAPK signaling pathway-related proteins (ERK1/2,p-ERK1/2,JNK,p-JNK,p38MAPK,p-p38MAPK)in hippocampal were detected by Western blot.Results Compared with natural aging group, TFE obviously improved the morphology and structure of hippocampal neurons,and the nerve cells arranged neatly and closely. Furthermore, TFE significantly downregulated the protein expression levels of p2 1 and Bax,upregulated the protein expression levels of Bcl-2 and the ratio of Bcl-2/Bax,and reduced the expression of NF-κB p65 and of its downstream inflammatory fac-tors TNF-α, IL-1β, COX-2, and MAPK signaling pathway-related proteins (p-ERK1/2,p-JNK and p-p38 MAPK ) in hippocampus of natural aging rats. Conclusions TFE effectively protects against inflam-matory reaction in brain aging of SD male rats.The mechanism is related with inhibition of NF-κB nuclear translocation and reduction of its downstream inflamma-tory cytokines expression by inhibiting MAPK signaling pathway activation.

Objective To investigate the mechanism of hearing loss after focal cerebral ischemia-reperfusion injury in rats.Methods A total of 60 healthy male adult SD rats were included in this study and randomly divided into 2 groups, ischemia-reperfusion(I/R) group and sham operated control, with 30 rats in each group.The rats in I/R group were operated for suture-occluded method to establish middle cerebral artery occlusion(MCAO)model, with ischemia for 60 mins followed by reperfusion for 24 hrs.The control group was only to be isolated cervical vessels, with no thread embolism inserted.The auditory brainstem response (ABR) was tested before operation and at 24 hrs post-operation respectively.At 24 hrs post-operation, we scored neurological functions, measured the changes of water content in the brain using the dry-wet weight method, and determined the infarct volume through TTC method.We also evaluated the integrity of blood-brain barrier(BBB) by viewing the exudation of Evans blue and observed the apoptosis of neurocyte by TUNEL method to conclude apoptotic index(AI).The expression of MMP-9,Claudin-5,Occludin and CX-43 were detected by Western blot.Results Compared with the sham group,the neurological function scores,the infarct volume and water content of the brain increased, with the elevated thresholds of ABR significantly and AI went up in I/R group.The expression levels of MMP-9 and CX-43 were significantly up-regulated,but the expressions of Claudin-5 and Occludin were obviously down-regulated.All of the differences above had statistical significances.Conclusion The mechanism of hearing loss after focal cerebral ischemia-reperfusion injury in rats is possibly related to MMPs activation,neurocyte apoptosis,BBB breakage and gap junction damage.

Objective To explore the diagnostic value of contrast-enhanced ultrasound (CEUS) in detecting small liver metastasis (SLM) from breast cancer. Methods A total of 92 cases diagnosed as breast cancer by surgical pathology and suspected SLM by conventional ultrasonography were included in this study. CEUS was used to check liver lesion in patients. The biopsy operation was used as the gold standard. The coincidence rate of benign and malignant pathology was used to compare the consistency between CEUS and biopsy pathology. Results In 92 cases suspected liver metastases of breast cancer by routine ultrasound, there were 54 cases were diagnosed as benign by pathology, and all 92 cases were diagnosed as benign by CEUS. Thirty-eight cases were diagnosed as metastasis by pathology, in which 36 cases were correctly diagnosed by CEUS. The sensitivity of CEUS for the diagnosis of liver metastases of breast cancer was 94.74%(36/38), specificity was 100%(54/54), positive predictive value (PPV) was 100%(36/36) and negative predictive value (NPV) was 96.43%(54/56). Conclusion CEUS has a higher diagnostic value in SLM of breast cancer, and has clinical practical value.
