Objective To explore the relationship between fasting serum concentration of uric acid (SUA)and the secretion of insulin under oral glucose tolerance test(OGTT)in 877 eligible subjects.Methods A 75g OGTT was administrated to all 877 eligible subjects,fasting uric acid,concentration of glucose and insulin of 0,30,60,120 and 180 min utes after OGTT were measured.Subjects were divided into high SUA group (HUA)and normal SUA group (NUA)according the concen-tration of SUA.SPSS 13.0 were used to analyze these data.Results Subjects in HUA had higher concentration of insulin in 0,30,60,120 and 180 min utes than NUA.There were positive correlation between SUA and INS in 0,30,60,120 and 180 min utes,Pearson r-value was 0.107,0.154,0.195,0.157 and 0.112(all P <0.01)respectively.By stepwise linear regression analyze,there were four parameters correlated with SUA:gender(female),INS60,cholesterol (TC),high density lipoprotein (HDL),β-vaule was -0.214,0.194,0.253,-0.119 (all P <0.01)respectively.Conclusion SUA positive correlated with secretion of INS after glycemia burden,SUA may be used as a potential biomark of secretin of INS (especially the concentra-tion of INS 60).

A growing number of people with unilateral breast cancer have chosen to undergo contralateral prophylactic mastectomy in order to prevent the occurrence of second primary breast cancer and thus avoid associated treatment and death. Contralateral prophylactic mastectomy has been considered beneficial in high-risk populations, such as premenopausal BRCA1/2 mutation carriers. As a result, contralateral prophylactic mastectomy acceptance in patients with no such mutation is controversial. Contralateral prophylactic mastectomy can reduce the risk by up to 95%. Therefore, it is very important to evaluate the risk of contralateral breast cancer and to make appropriate surgical treatment. A review of risk factors for contralateral breast cancer and the benefits of contralateral prophylactic mastectomy in patients with unilateral breast cancer is presented.

Objective To compare the performance of four commercial anti-dsDNA antibody assays,i.e,BioPlex 2200 (BioPlex),Farr radioimmunoassay (Farr),MESACUP DNA-Ⅱ TEST ds [MBL-enzyme linked immunosorbent assay (ELISA)] and Anti-dsDNA-NcX ELISA (IgG) (EURO-ELISA),Antoantibodies Profile Assay Kit (HOB-Chemiluminescent Immunoassay) in disease activity assessment of systemic lupus erythematosus (SLE).Methods SLE patients (n=119) as well as healthy controls (n=200) and disease controls (n=100) were recruited and their serum anti-dsDNA antibodies were detected by BioPlex,Farr,MBL-ELISA,EURO-ELISA,and a standard Crithidia luciliae indirect immunofluorescence test (CLIFT).The consistency between above four methods to CLIFT was analyzed.The correlation of anti-dsDNA antibody level of these four methods to SLE disease activity was assessed.All data analyses were performed with Statistical product and service solutions (SPSS) 16.0 (SPSS.Inc) and GraphPad Prism 4.0.3 (GraphPad).Unless otherwise specified,all data in this study were expressed as mean±standard deviation.Cut-off values of the anti-dsDNA quantification methods were set by the manufacturers.Chi square and kappa coefficients were adopted to assess the agreement determination and correlation analysis between anti-dsDNA level and SLE disease activity (SLEDAI).Receiver-operator characteristic (ROC) curve analysis was used to compare the specificity and sensitivity of the anti-dsDNA assays.Student's t test was adopted for the comparison of anti-dsDNA levels by different methods between SLE and SLE+LN groups.A p value small than 0.05 was considered statistically significant.Results Using cut-off values set by the manufacturers,BioPlex demonstrated the highest overall agreement with CLIFT,while MBL-ELISA and EURO-ELISA showed the highest positive agreement with CLIFT.Disease activity correlation analysis showed that SLEDAI score correlated poorly with anti-dsDNA level in Farr assay,but strongly with the other three assays.Bioplex had a better performance in terms of SLE activity index corelation (r=0.297 6,P=0.001 2).Moreover,anti-dsDNA level differed in SLE patients with renal lupus nephritis in BioPlex assay (P=0.026 8),but not in the other assays.In ROC curve analysis,BioPlex showed the largest area under the curve (AUC) over other assays.Conclusion Bio Plex assay has better sensitivity and specificity than Farr,MBL-ELISA and EURO-ELISA and correlates well with SLE disease activity.

OBJECTIVE: To analyze the relationship between traditional Chinese medical syndromes and fungal pneumonia for moderate and advanced lung cancer patients. METHODS: We retrospected 115 moderate and advanced lung cancer patients with different syndromes in traditional Chinese medicine (qi deficiency, yin deficiency, blood deficiency, yang deficiency, blood stasis, phlegm dampness, phlegm heat, damp heat, cold dampness, qi stagnation, heat toxin), who had the concurrent fungal pneumonia, and used regression analysis method to analyze the data. RESULTS: When the patients had the phlegm heat syndrome, they got a significantly higher risk of having fungal pneumonia (P < 0.01); and when they had the heat toxin syndrome, they also had a high risk of having fungal pneumonia (P < 0.05). CONCLUSION: The phlegm heat and heat toxin syndromes are the risk factors for moderate and advanced lung cancer patients having concurrent fungal pneumonia.

Objective To explore the clinical factors on the functional recovery of spinal cord cavernous hemangioma operation. Methods Fifty cases patients with complete spinal cord cavernous hemangioma were retrospectively analyzed their clinical data and its influence on prognosis of 2 years. Single factor and multiple factors analysis were performed. Results Compared with the preoperative stage,the grade of Aminoff-Logue score of 28 cases(50. 9%)had improved at least one grade,14 cases(25. 5%)patients with no significant changes and 13 cases(23. 6%)with decreased one grade at least. Logistic regression model showed that patients with clinical types(OR=3. 27,95%CI 2. 34-15. 83,P=0. 006),the time of the attacks to the surgery(OR=2. 93,95%CI 1. 41-10. 61,P=0. 012),and the attacks to the operation time( OR=4. 31,95%CI 2. 46 -12. 32,P = 0. 019 ) were related to neurological function recovery of spinal cord cavernous hemangiomas. Conclusion For patients with SCH dysfunction,regardless of what kind of clinical types of neurological dysfunction extent,should receive surgical treatment to improve neurological function recovery rate as soon as possible.

[Objective]To investigate the expression change of miR-134 in methamphetamine(MA)-induced neuronal injury in PC12 cells and its effect on neuronal excitability and understand the pathogenesis of methamphetamine-induced neuronal injury.[Methods]PC12 cells in the logarithmic phase were divided into control group and MA group. The MA group was treated with 800μmol/L MA to establish the model of neuronal injury. The cellular injury was observed under microscope. The neuronal apoptosis was detected by Hoechst3342/PI double staining,and miR-134 expression was measured by using real-time quantitative PCR (Real time-PCR). Furthermore,we constructed miR-134 interference vector and observed its effect on evoked action potential.[Results]The cultured PC12 cells were damaged under the 800 μmol/LMA treatment ,and neurites became shorter ,the apoptotic cells were evidence. Real time-PCR showed that miR-134 expression was increased after MA treatment. Electrophysiological data showed that the evoked action potential increased after miR-134 interference.[Conclusions]High concentration of MA can induce neuronal damage and apoptosis and also increase miR-134 expression. While silence miR-134 expression can increase neuronal excitability.Our study provides an experimental basis for elucidating the possible mechanism of MA-induced neuronal injury and the role of miR-134 in neurotoxicity and neuronal excitability.

Objective:To observe the effects of static 70° head-up tilted standing and of repeated body repositioning on hemodynamics in healthy young and middle-aged persons.Methods:The hemodynamics of 24 middle-aged and 23 younger persons were studied. Both groups were requested to perform static 70° head-up tilted standing and to repeatedly change their body position from 0° to 70° of tilt at a velocity of 1°/second for ten minutes in a random order. Before, between and after each test the subjects rested supine for ten minutes. Hemodynamic variables and blood pressure were recorded non-invasively.Results:The average heart rate (HR) increased significantly in both groups when rising from supine to the testing positions. In 70° tilted standing the average HR of the youth group, 84.0±9.5bpm, was significantly higher than that in the other position and that of the middle-aged group in the same position. The average HR of the middle-aged group in 70° tilted standing was also significantly higher than in the other position. Among the middle-aged group, the average stroke volume (SV) in the testing positions was significantly lower than when resting. Significant differences were observed in the average diastolic blood pressure (DBP) between the testing and rest positions for both groups, with the average DBP of the middle-aged group significantly higher than that of the youth group in all three positions. Among the youth group, the average SV, CO and systolic blood pressure (SBP) of the males were significantly higher than among the females in all of the different body positions.Conclusions:Young persons mainly rely on an increased heart rate to maintain cardiac output while middle-aged participants appear to achieve this through increased peripheral resistance. Repeated position changes have less impact on hemodynamics than 70° inclined standing, making it a safer and more stable training method. However, the long-term effects of such intervention need to be confirmed in further studies.

Kidney ischemia-reperfusion injury (IRI) is the major cause of poor prognosis after kidney transplantation and partial nephrectomy. Besides, it is also a critical pathophysiological process of acute kidney injury. Consequently, the prevention and treatment of kidney IRI are of significance to improve clinical prognosis of recipients undergoing kidney transplantation. However, the mechanism underlying IRI is complex, and the exact mechanism remains elusive. Inflammation, as one of the main pathogenesis of IRI, plays a significant role in IRI-induced kidney injury. Nuclear factor (NF)-κB, as a rapid response transcription factor, has been proven to be involved in the regulation of inflammation during kidney IRI. Therefore, in this article, the structure of NF-κB, the activation pattern of NF-κB signaling pathway, the regulatory mechanisms of NF-κB upstream and downstream signaling pathways in kidney IRI were reviewed, and the role of NF-κB signaling pathway in kidney IRI was investigated, aiming to provide novel clinical ideas for the prevention and treatment of kidney IRI.
