Farnesoid X receptor (FXR) belongs to the nuclear receptor superfamily. It is highly related to the formation of metabolic syndrome and the glucose homeostasis, and therefore represents an important drug target against metabolic diseases and diabetes. In recent years, great progress has been made in the agonists, antagonists, and crystal structures of FXR. The diverse FXR ligands and their structure-activity relationship are reviewed in this article. The advances in the crystal structures of FXR in complex with different ligands are also introduced.

Objective To explore the effect of endotracheal intubation therapy on acute laryngotracheobronchitis and acute laryngitis in children.Methods Twelve of 45 children with acute laryngotracheobronchitis or acute laryngitis were intubated and mechanically ventilated in pediatric intensive care unit (PICU) during Oct. 2000 to Oct. 2006.Ten cases were laryngotracheobronchitis and 2 were acute laryngitis.The endotracheal tube chosen was at least 0.5 to 1.0 size smaller than normally recommended for age.The need of intubation was assessed based on severity of signs of airway obstruction Ⅲ without improvement by the conventional treatment with humidified and combined with oral or intravenous interventions,respiratory failure,or airway obstruction Ⅳ.Results Eleven of 12 children were intubated successfully,except 1 case after resuscitation.All the patients were ventilated after intubation.The mean duration of intubation was 3.4 days (24 hours -9 days).Ten cases were successfully extubated and 2 cases failed of extubation,of which 1 case got tracheostomy.All children were routinely supported by nasal continuous positive airway pressure(NCPAP) after extubation with a mean of 1.5 days (2 hours-4 days).The mean days of hospitalization were 11.2 days (4-22 days).Conclusion Intubation is an alternative for the management of severe acute laryngotracheobronchitis and acute laryngitis in children.In most cases,tracheotomy can be substituted by intubation.

Objective To discuss the protective effect of doxofylline on radical surgery for esophageal cancer.Methods Under elective general anesthesia, 60 cases, 35 males and 25 females, aged 45-70 years, BMI 20-30 kg/m2, ASA physical status Ⅰ or Ⅱ, FEV1%>50%, underwent radical surgery for esophageal cancer at middle and distal parts.Random number table was employed to divide these patients into two groups: doxofylline group (group D) and control group (group C) with 30 cases in each.After a routing intravenous induction in the two groups, mechanical ventilation was conducted after bronchial intubation with double channel catheter on the right side.The intravenous injection of doxofylline 4 mg/kg in group D was administrated 30 min after bronchial intubation with double channel catheter.Equal normal saline was instilled to the patients in group C.Blood samples were taken from radial artery to detect the levels of TNF-α, IL-6, IL-10, MDA and SOD at four time points: 10 min (T0) before the one-lung ventilation, 60 min after OLV (T1), after two-lung ventilation (T2) and the end of the operation (T3).Meanwhile, the blood and breath at these time points were tested.The occurrence of OLV, blood loss volumes, fluid input quantities, urine volumes, postoperative hyoxemia and pulmonary inflammation were observed.Results Compared with T0, the activity of SOD in serum and PaO2 in the two groups at T1-T3 decreased (P＜0.05).The concentrations of TNF-α, IL-6, IL-10 and MDA increased significantly (P＜0.05).Compared with group C, the activity of SOD activities and PaO2 in group D at T1-T3 increased while concentrations of TNF-α, IL-6, IL-10 and MDA decreased significantly (P＜0.05).The occurrence rates of postoperative hyoxemia and pulmonary inflammation in group D were obviously lower than those in group C (P＜0.05).Conclusion Doxofylline can suppress patients' inflammatory response and oxidative stress response after OLV and reduce the incidence rates of postoperative hyoxemia and pulmonary inflammation as well as alleviate lung injury triggered by radical surgery for esophageal cancer.

Objective To describe the prevalence and change of rationing of nursing care (RNC) in medical and surgical units of level 2 and level 3 general hospitals across Guangdong province. Methods RNC were measured by asking nurses about the completion status of 12 necessary nursing care activities, and the prevalence of RNC in 2014 was compared with the study results from the China Hospital Nursing Workforce Research(CNWR) in 2009 (exclusively using the data of Guangdong province) to describe the change of RNC. Results Six activities were rationed averagely in 2014, and the most frequent activities rationed wereComfort/talk with patients accounted for 69.8% (975/1 396) andEducating patients and familiesaccounted for 67.3%(940/1 396). According to the CNWR in 2009, the average number of nursing care activities rationed was 3 which was statistically lower than the number in 2014 (P < 0.01). Conclusions RNC is prevalent in level 2 and level 3 general hospitals across Guangdong province, especially psychosocial care to the patients; the prevalence of RNC has not decreased since 2009.

Objective:To assess the implementation of injection-related risk management based on WeChat platform for type 2 diabetic patients with the insulin self-injection.Methods:A total of 124 diabetic patients, who would receive insulin therapy by self-injection at home after discharge from the PLA 903 hospital during April 2017 to July 2018, were divided into the control group( n=62)and the study group( n=62). All patients were given routine education on insulin injection during the hospitalization,while the study group( n=62)received additional video and text education based on WeChat platform after discharge. The skill of self-injection and the status of blood glucose control were evaluated in both groups 4 weeks and 8 weeks after discharge, respectively. Results:The insulin injection skill, including skin disinfection [36(58%) vs. 11(18%),χ 2=21.42, P<0.01], exhaust before injection [62(100%) vs. 51(82%),χ 2=12.07, P<0.01], stay 10s after injection [60 (97%) vs. 47(76%),χ 2=11.52, P<0.01], disposal of used needle[49(79%) vs. 18(29%),χ 2=31.20, P<0.01], rotation of injection site [48(77%) vs. 35(56%),χ 2=6.16, P=0.01], insulin storage [62(100%) vs. 57(92%),χ 2=5.21, P=0.02], and the ability of correctly dealing with hypoglycemia [52(84%) vs. 38(61%),χ 2=7.94, P=0.01] in the study group were significantly better than those in the control group after 4 weeks of injection-related risk management. The fasting plasma glucose [(6.41±0.76) vs.(7.19±0.81)mmol/L, t=5.61, P<0.01], glycosylated hemoglobin A1c [(6.71±0.64)% vs. (7.37±0.78)%, t=5.18, P<0.01], incidence of hypoglycemia [6(10%) vs. 15(24%),χ 2=4.64, P=0.03] in the study group were significantly lower than those in the control group after 12 weeks of the management. Conclusion:The risk management based on WeChat platform can improve insulin self-injection skill and the ability of dealing with hypoglycemia,also promote effective blood glucose control for diabetes patients.

Objective:To evaluate the clinical performance of CAD/CAM zirconia all-ceramic restorations.Methods:287 all-ce-ramic Zirconia restorations in 206 patients were included in a 3-year prospectively survey with California Dental Association Standard (CDA)as a reference.The effects and the related factors such as restoration type,tooth region,fiber reinforced composite application on survival rate were analyzed.Kaplan-Meier survival analysis and Log-Rank test were used for data analysis.Results:Chipping frac-tures in 5 restorations,intense gingivitis at 4 restorations and periapical inflammation for 3 restorations were observed during the obser-vation period.The 3-year cumulative survival rate (CSR)of CAD/CAMzirconia restorations was 95.7%,The differences among the CSR of single crowns(96.3%),linked crowns (93.6%)and fixed partial dentures(95.7%)were not statistically significant(P >0.05).The difference was not statistically significant(P >0.05)between the CSR of the anterior region group(94.5%)and posterior region group(96.3%)as well as difference(P >0.05)between the CSR of fiber reinforced composite group (95.0%)and without fiber reinforced composite group(96.1%).Conclusion:The cumulative survival rate of CAD/CAM zirconia all-ceramic restorations is high.Chipping fracture is the main reason of failure.Restoration type,tooth region and fiber reinforced composite have no significant effect on the survival of zirconia restorations.
