Objective To investigate the correlation of nuclear factor‐κB (NF‐κB) with metabolic syndrome(MS). Methods A total of 240 subjects living in rural areas of Ningxia were enrolled in this study and divided into two groups :MS group (n= 120 ) and healthy control group (n= 120 ). The relationship of NF‐κB with MS was evaluated by t‐test ,partial correlation and conditional logistic regression analysis. Results Whole blood NF‐κB protein level was significantly lower in MS group than in control group [(352.31 ± 307.35) vs (441.00 ± 345.10) ng/L ,P<0.05]. Whole blood NF‐κB protein level was significantly lower in male ,Han nationality ,and 45~55 years old patients of MS group than in control group (P<0.05). Partial correlation analysis showed that NF‐κB was associated with BMI (β=-0.146 ,P=0.025) .Conditional logistic regression analysis showed that whole blood NF‐κB protein was a protective factor for MS (OR=0.91 ,95% CI:0.72~0.98 ,P<0.05). Conclusion The blood NF‐κB level is associated with MS.

To improve the quality of experimental teaching,investigating the independent design experiments are carrying out in preventive medicine by public health experimental teaching center in our school.We take preventive medicine professional as an example,and besides the classical basis experiments,some experiments are verification project at present,in which students are not strongly interested.On the basis of the integration of the classic experiments,according to the national standard of the experimental method,we are trying to carry out part of the independent design experiments to meet the needs of students learning.The effect of those independent design experiments shows that it is appropriate carrying out independent design experiments on the basis of the existing classical experimental project in preventive medicine experimental teaching,to a certain extent,which will stimulate students' learning interest and enhance their sense of achievement.This study is conducive to the cultivation of medical students' innovation,independent thinking,analysis and problem-solving ability,practical ability and teamwork spirit.

Objective To investigate the Clinical safety and effectiveness of propofol medium and long chain fat emulsion injection for cesarean section. Methods A retrospective analysis was conducted in 88 cesarean section surgeries performed between January, 2014 and June, 2015 with epidural anesthesia in 44 cases (control) and with total anesthesia with propofol/long chain fat emulsion injection in 44 cases (observation group). The maternal mean arterial pressure (MAP), SpO2, and heart rate and neonatal umbilical dynamic venous blood gas analysis (pH, PO2, pCO2) were compared between the two groups. Results Compared with the control group, heart rate and MAP significantly increased at skin incision in the observation group. At the other time points, heart rate, MAP, and SpO2 were all comparable between the two groups. The time from skin incision to newborn delivery was significantly shorter in observation group (P<0.05), but the time from uterine incision to delivery and neonatal Apgar score were equivalent between the two groups (P>0.05);neonatal umbilical arteriovenous blood pH, PO2, and pCO2 were all comparable between the two groups. Conclusion Propofol medium and long chain fat emulsion injection for general anesthesia induction in cesarean section is characterized by rapid metabolism of the anesthetics, rapid maternal postoperative recovery, and minimal adverse effects on the fetus, and is therefore safe and reliable in clinical use.

Objective:To investigate the prognostic value of preoperative peripheral blood albumin-to-globulin ratio (AGR) for patients with non-metastatic clear cell renal cell carcinoma (NMCCRCC).Methods:The clinicopathological and postoperative follow-up data of 61 patients with NMCCRCC confirmed by postoperative pathology who were admitted to Zhongshan Hospital of Dalian University from January 2012 to December 2014 was retrospectively analyzed. According to the receiver operating characteristic curve (ROC), the optimal cut-off value of AGR was determined. According to the cut-off value, the patients were divided into high AGR group (AGR≥1.59) and low AGR group (AGR<1.59). The factors affecting the prognosis of NMCCRCC patients were analyzed by using univariate and multivariate analyses.Results:Among 61 patients with NMCCRCC, 38 cases (62.3%) were in high AGR group and 23 cases (37.7%) were in low AGR group. The differences in age, globulin level, clinical staging, and recurrence status between the two groups were statistically significant (all P < 0.05). The overall survival time and disease-free survival time in low AGR group were shorter than those in high AGR group, and the differences were statistically significant (both P < 0.05). Multivariate Cox regression analysis showed that AGR < 1.59 was the independent influencing factor for overall survival and recurrence ( HR = 0.233, 95% CI 0.073-0.742, P = 0.014; HR = 0.343, 95% CI 0.134-0.873, P = 0.025). Conclusion:Preoperative AGR is valuable in predicting the prognosis of NMCCRCC patients.
