Objective To investigate the effect of Biyankang Tablets on quality of life and recurrence rate in patients with chronic rhinosinusitis after functional endoscopic sinus surgery (FESS). Methods A total of 78 patients with chronic rhinosinusitis treated in our hospital during October 2014 to November 2016 were selected, and they were randomly divided into the control group and the traditional Chinese medicine (TCM) group according to the order of admission, with 39 cases in each group. Both groups were treated with FESS, and the TCM group was additionally treated with Biyankang Tablets. The clinical efficacy, inflammatory factors [interleukin-4 (IL-4), interleukin-8 (IL-8)], the prognosis [visual analogue scale (VAS) score of rhinosinusitis and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30)], drug safety and recurrence rates in the two groups were observed. Results After treatment, the total effective rate of treatment in TCM group was significantly higher than that in the control group (89.74% vs 71.79%) (χ2=4.044, P<0.05). After treatment, IL-4, IL-8 and VAS scores in the two groups were significantly decreased, and the scores of EORTC and QLQ-C30 were significantly increased, and the changes of scores in TCM group after treatment were more significant than those in the control group (P<0.05). After treatment, there was no significant difference in the incidence of adverse reactions between the two groups, and the recurrence rate in TCM group was significantly lower than that in the control group in 1 year after treatment (P<0.05). Conclusion TCM Biyankang Tablets is significantly effective in the treatment of patients with chronic rhinosinusitis after FESS. It can significantly inhibit the expression of inflammatory factors, effectively improve the prognosis and quality of life, and significantly reduce the recurrence rate.

Objective The aim of this study was to elucidate the effects of homocysteine (Hcy) on the expression and secretion of tissue factor pathway inhibitor (TFPI) in endothelial cells (Ecs). Methods Cultured human umbilical vein endothelial cells (HUVECs) (ECV-304 strain) were incubated with homocysteine (Hcy) in different concentrations of 0, 25, 50, 100?mol/L, and 1,5,10mmol/L, respectively, for 24 hours. Cell viability was then determined by MTT assay, and lactate dehydrogenase (LDH) released into the culture medium was measured to assess cell damage. Antigen levels of the free form of TFPI after Hcy exposure were measured in culture media with ELISA (Diagnostica Stago, France). Furthermore, the total content of TFPI was assessed with cellular ELISA. Results Hcy in concentrations of 0～1mmol/L did not produce cell toxicity as shown by cell viability and LDH determination in culture media after 24 hours of incubation. When the endothelial cells were exposed to concentrations up to 5mmol/L, cell viability decreased, and a higher concentration of Hcy (10mmol/L) elicited a significant cytotoxic effect, as shown by a decreased cell viability and a higher amount of LDH in culture supernatants compared with the control cells. All the TFPI absorbance values in Hcy-treated cells and the free TFPI levels in culture supernatants were significantly increased, especially in the 50?mol/L group. Conclusion A lower concentration of Hcy did not show signs of cell toxicity but it could promote the expression and secretion of TFPI. The results can help us partly explain why the TFPI level was increased in some patients with hyperhomocysteinemia. They also suggested that Hcy could play an important role in the modulation of coagulation processes in blood circulation.

Objective To investigate behavioral disposition of nurses in emergency room and analyze influential factors.Methods A total of 200 nurses from the emergency room participated in the survey using demographic questionnaire and the nursing behavior questionnaire.Results The total average score of the nursing behavior was(3.13±0.54),and the influential factors included the level of hospital,the time span for the job and the continued education on the infectious diseases(all P<0.01).Conclusions The nursing behaviors was at the medium level.The nursing administrators should provide the nurses with personal protection apparatus,strengthen education on infectious diseases and use incentive mechanism so as to improve the ER nurses' nursing behavior.

Objective To study the effects of the HBV x gene (HBx) on the biological characteristics and the expression of DNA repair enzyme hMTH1 mRNA of the L02/HBx transgene cell model. Methods Light microscopy was used to observe the morphologic characteristics of gene-transfected cell strain Lff2/HBx that stably expressed the HBx protein and the control groups of L02 and L02/PcDNA3.1. The changes of L02/HBx on the proliferation, cell cycle and apoptosis were observed by MTT assays and flow cytometry analysis respectively. Moreover, the malignant transformation of L02/HBxwas assayed by colony formation in soft agar and the expression of DNA repair enzyme hMTH1 mRNA was assayed in each group by real-time qPCR. Results Inversion phase contrast microscope showed that the morphologic characteristics of L02/HBx had changed obviously compared with control groups. The MTT showed that L02/HBx proliferated more quickly and flow cytometry analysis indicated that HBx could accelerate the progression of cell cycle and inhibit apoptosis. Colony formation in soft agar demonstrated that the rate of colony formation of L02/HBx was remarkably higher than the L02 and the L02/peDNA3. 1 cells (P<0. 05). The real-time qPCR detection showed that the expression of hMTH1 mRNA in L02/HBx was significantly higher than that in the control groups ( P < 0. 05 ). Conclusion HBx could play an important role in the malignant transformation of L02/HBx and the over expression of hMTH1 mRNA.

Objective To investigate effectiveness of anthropometric parameters and body composition analysis for the screening and prediction of metabolic syndrome and explore the best indicator for predicting metabolic syndrome in the elderly. Method A cross-sectional study of 763 (406 men and 357 women) elderly people who participated in the annual health check-up was conducted. Clinical data of all participants were obtained including anthropometric parameters, body composition, lipid profiles, fasting blood glucose, and high sensitivity C-reactive protein. Receiver operating characteristic (ROC) curve was used to determine the optimal cutoff points for waist circumference, waist-to-hip ratio, waist-to-height ratio, percent body fat and fat mass index in relation to the area under the curve (AUC), sensitivity and specificity in the screening and prediction of metabolic syndrome. Result In total subjects, compared with non-metabolic syndrome group,the ROC curve analysis showed that parameters including waist circumference, waist-to-height ratio, waist-to-hip ratio, percent body fat and fat mass index had a significant potential for predicting metabolic syndrome (P<0.001). It was determined that waist circumference of 87.5 cm and 77.5 cm, waist-to-hip ratio of 0.89 and 0.87, waist-to-height ratio of 0.51 and 0.52, percent body fat of 24.1%and 31.7%and fat mass index of 5.00 kg/m2 and 7.80 kg/m2 were the optimal cutoff points for screening and predicting the presence of metabolic syndrome among men and women with a sensitivity of 81.3%,78.8%,87.5%, 51.3%and 83.8%(in men) and 85.1%,79.8%,71.3%, 70.2%and 80.9%(in women) and a specificity of 57.7%,62.6%,50.0%, 75.5%and 51.8%(in men) and 38.0%,53.2%,55.1%, 50.6%and 52.5% (in women),respectively. The area under the ROC curve (AUC) was 0.728, 0.755, 0.716, 0.671 and 0.725 in men and 0.652, 0.707, 0.658, 0.619 and 0.675 in women,respectively. Waist-to-hip ratio showed the highest AUC in all the parameters in men and women. Conclusion Anthropometric parameters and body composition analysis play important roles in the screening and prediction of metabolic syndrome, and waist-to-hip ratio seems to be the best parameter in the screening and prediction of metabolic syndrome in the elderly.

Objective:To investigate the relationship between cancer-related fatigue and cortisol in cancer patients and elucidate the underlying mechanism. Methods:A total of 80 cancer cases were divided into two groups:fatigue group (50 cases with cancer-related fatigue) and non-fatigue group (30 cases without fatigue). The scores were evaluated through the Multidimensional Fatigue Symptom Inventory-Short Form (MFSI-SF) and the Fatigue Symptom Inventory (FSI) report. Serum specimens were examined through electrochemiluminesence immunoassay and enzyme-linked immunosorbent assay. Serum cholesterol was examined through the CHOD-PAP method, and serum total protein and albumin were determined via the Biuret method. Agarose gel electrophoresis was conducted to determine alpha 2 globulin ratio and to calculate serum alpha 2 globulin concentration. Results: The cortisol level in the fatigue group was significantly lower than that in the non-fatigue group[(119.68±5.34) nmol/L vs. (163.45± 31.49) nmol/L, P<0.05], and the adrenocorticotropic hormone (ACTH) level in the fatigue group was significantly higher than that in the non-fatigue group [(104.50 ± 17.15) ng/L vs. (51.43±13.24) ng/L, P<0.05]. Cortisol negatively correlated with MFSI-SF (r=-0.867, P<0.001) but positively correlated with ACTH (r=0.809, P<0.001). Furthermore, cortisol negatively correlated with FSI (r=-0.747, P<0.001) but positively correlated with ACTH (r=0.70, P<0.001). The levels of serum cholesterol [(1.25±0.70) mmol/L vs. (3.28±0.73) mmol/L, P<0.05], albumin[(18.24 ± 7.03) g/L vs. (37.40 ± 8.05) g/L, P<0.05], and alpha-2 globulin [(2.25±1.07) g/L vs. (5.36±1.09) g/L, P<0.05]were significantly lower in the fatigue group than in the non-fatigue group. Conclusion:The patients with cancer-related fatigue exhibited increased MFSI-SF score, decreased serum cortisol level, and enhanced ACTH level. The low serum cortisol levels caused a disorder in the serum ACTH and cancer-related fatigue of malignant tumor patients. The mechanism underlying the reduction in serum cortisol level correlated with the insufficient amounts of serum cholesterol, the composite material of cortisols, and of serum albumin, particularly alpha-2 globulin, the carrier protein of serum cholesterol.

An electrochemical sensor incorporating a signal enhancement for the determination of lead (Ⅱ) ions (Pb2+) was designed on the basis of the thrombin-binding aptamer (TBA) as a molecular recognition element and ionic liquid supported cerium oxide (CeO2) nanoparticles-carbon nanotubes composite modification. The composite comprises nanoparticles CeO2, multi-wall carbon nanotubes (MWNTs)and hydrophobic room temperature ionic liquid (RTIL) l-ethyl-3-methylimidazolium tetrafluoroborate (EM1MBF4). The electrochemical sensors were fabricated by immersing the CeO2-MWNTs-EMIMBF4 modified glassy carbon electrode (GCE) into the solution of TBA probe. In the presence of Pb2+, the TBA probe could form stable G-quartet structure by the specific binding interactions between Pb2+ and TBA. The TBA-bound Pb2+ can be electrochemically reduced, which provides a readout signal for quantitative detection of Pb2+. The reduction peak current is linearly related to the concentration of Pb2+ from 1.0 × 10 8 M to 1.0 × 10-5 M with a detection limit of 5 × 109 M. This work demonstrates that the CeO2-MWNTs-EMIMBF4 nanocomposite modified GCE provides a promising platform for immobilizing the TBA probe and enhancing the sensitivity of the DNA-based sensors.

Objective To investigate the efficacy and safety of different doses of dezocine at different administration time on analgesia after laparoscopic cholecystectomy.Methods 80 patients elected from ASA Ⅰ-Ⅱ grade laparoscopic cholecystectomy were randomly divided into four groups,20 cases in each group.Group Ⅰ was anesthetized by intravenously injected dezocine 0.10mg/kg before the surgery,group Ⅱ was anesthetized by dezocine 0.15mg/kg before the surgery,group Ⅲ was anesthetized by intravenously injected dezocine 0.10mg/kg after stopping anesthetic surgery,and group Ⅳ was anesthetized by intravenously injected dezocine 0.15mg/kg after stopping anesthetic surgery.The postoperative pain scores were observed 1,6,12,24 hours after operation in the four groups by using visual analog scale (VAS),comfort score (BCS),and anesthesia recovery score (modified Aldrete score).Results TheVAS of the four groups 1 hour after surgery:group Ⅰ and group Ⅲ was significantly different(t =2.308,P =0.036),group Ⅰ and group Ⅳ was significantly different (t =2.106,P =0.042),group Ⅱ and group Ⅲ was significantly different (t =2.711,P =0.014),group Ⅱ and group Ⅳ was significantly different (t =2.317,P =0.037).The BCS 1 hour after surgery:group Ⅰ and group Ⅲ was significantly different(t =2.108,P =0.042),group Ⅰ and group Ⅳ was significantly different(t =2.069,P =0.048),group Ⅱ and group Ⅲ was significantly different (t =2.353,P =0.033),group Ⅱ and group Ⅳ was significantly different (t =2.361,P =0.036).The VAS 6 hours after surgery:group Ⅰ and group Ⅲ was significantly different (t =2.084,P =0.045),group Ⅱ and group Ⅲ was significantly different(t =2.309,P =0.038),group Ⅱ and group Ⅳ was significantly different(t =2.303,P =0.040).The BCS 6 hours after surgery:group Ⅰ and group Ⅲ was significantly different (t =2.294,P =0.041),group Ⅱ and group Ⅲ was significantly different(t =2.322,P =0.035),group Ⅱ and group Ⅳ was significantly different (t =2.070,P =0.048).The BCS 12 hours after surgery:group Ⅱ and group Ⅲ was significantly different(t =2.518,P =0.047).VAS and BCS scores at other time points had no significant difference (P ＞ 0.05).Conclusion The analgesic after laparoscopic gallbladder surgery using dezocine 0.10mg/kg-0.15mg/kg,especially 0.15mg/kg administered anesthesia before surgery,can effectively relieve postoperative pain and improve postoperative comfort,reduce postoperative analgesic(pain pump) and has less adverse reactions,which is worthy of promotion.
