Objective To understand the current status of aloneness and analyze the influencing factors,and to provide reference to improve the aloneness among middle?aged and elderly. Methods A total of 994 middle?aged and elderly in Donggang sampled by stratified random sampling method were investigated by UCLA scale. The influencing factors were assessed by t?test and one?way ANOVA. The data were analyzed by SPSS 16.0. Results The average score of UCLA scale among middle?aged and elderly was 41.54 ± 8.91. The results indicated whether living with their children,alcohol drinking,quality of sleep,history of trauma,psychological counseling,monthly income,chronic disease and physical training were the influencing factors of aloneness among middle?aged and elderly,and the differences were statistically significant(P<0.05). Conclusion The aloneness was obvious among middle?aged and elderly in China. Health interventions and effective social support should be provided to improve the physiological,psychological and economic levels that will lead to important influence on the improvement of aloneness among middle?aged and elder?ly in China.

Objective:To evaluate the effect of trans-nasal humidified rapid insufflation ventilatory exchange (THRIVE) on reflux and micro-aspiration during induction of general anesthesia in the patients undergoing laparoscopic cholecystectomy.Methods:A total of 60 patients, regardless of gender, aged 18-60 yr, with body mass index of 18-28 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, scheduled for elective laparoscopic cholecystectomy, were divided into 2 groups ( n=30 each) using a random number table method: routine mask ventilation group (group C) and trans-nasal humidified rapid insufflation ventilatory exchange group (group H). Patients in group C were pre-oxygenated with a mask for 5 min, oxygen flow of 6 L/min and FiO 2 100%, after the induction of anesthesia, the pressure mask was used to artificially assist positive pressure ventilation for 2 min when the patient′s consciousness disappeared, and 2 min later endotracheal intubation was performed.Patients in group H were pre-oxygenated with THRIVE for 5 min, oxygen flow of 30 L/min and FiO 2 100%.The oxygen flow was increased to 50 L/min during anesthesia induction.After anesthesia induction, the oxygen flow was increased to 70 L/min when the patient′s consciousness disappeared, and chin lift and/or jaw thrust was used during apnoea to maintain an open airway, the patient′s mouth was kept closed during the whole process, and 2 min later endotracheal intubation was performed.Ultrasound was used to measure the cross-sectional area (CSA) of the gastric antrum and to monitor the occurrence of gastric insufflation, and the incidence of CSA greater than >3.4 cm 2 was recorded on admission to the operating room and immediately after tracheal intubation.Supraglottic and subglottic secretions were collected at the time of tracheal intubation using visual laryngoscopy after exposing the glottis, and the pepsin content was determined using enzyme-linked immunosorbent assay to assess reflux (content of pepsin in supraglottic secretion >216 ng/ml) and micro-aspiration (content of pepsinin subglottic secretion >200 ng/ml), and arterial blood gas analysis was simultaneously performed.The apnoea time was recorded, and P ETCO 2 at the first mechanical ventilation after tracheal intubation were recorded. Results:Compared with group C, PaO 2 was significantly increased and CSA was decreased immediately after tracheal intubation, and the incidence of CSA greater than >3.4 cm 2 immediately after tracheal intubation was decreased, and the incidence of gastric insufflation, reflux and micro-spiration was decreased, apnoea time was prolonged, and P ETCO 2 at first mechanical ventilation was increased in group H ( P<0.05). Conclusions:THRIVE applied during induction of general anesthesia can reduce the occurrence of reflux and micro-aspiration while ensuring oxygenation in the patients undergoing laparoscopic cholecystectomy.

Objective:To evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on postoperative pulmonary function in the patients undergoing robot-assisted radical resection of colon cancer.Method:Ninety-four patients of either sex, aged 50-80 yr, with body mass index of 18-25 kg/m 2, of American Society of Anesthesiologists physical status Ⅰ-Ⅲ, with ARISCAT grade of medium risk, undergoing elective robot-assisted radical resection of colon cancer, were enrolled in this study. The patients were divided into TEAS group (group T, n=47) and sham-TEAS group (group S, n=47) using a random number table method. In group T, patients received 30 min of TEAS at Hegu (LI4), Quchi (LI11), Zusanli (ST36) and Feishu (BL13) between 5: 00 and 7: 00 a. m. from 1st day before operation to 3rd day after operation, with disperse-dense wave 2/100 Hz, and the stimulation intensity was the maximum intensity that the patient could tolerate. Patients in group S were also connected to the device without electrical stimulation. Both groups adopted lung-protective ventilation strategy during operation. The oxygenation index was calculated at the time of entering the operating room (T 0), 5 min after anesthesia induction (T 1), 5 min of pneumoperitoneum (T 2), 5 min after changing to Trendelenburg position (T 3) and immediately after the end of pneumoperitoneum (T 4). Peak airway pressure, plateau airway pressure, driving pressure and dynamic lung compliance were recorded at T 0-T 4. The serum concentration of lung Clara cell 16 kDa protein was recorded using enzyme-linked immunosorbent assay at T 0, T 4 and 2 h after extubation (T 5). On 1 day before operation and 1, 3 and 7 days after operation, the forced expiratory volume in the first second (FEV 1) and forced vital capacity (FVC) were measured, and the FEV 1/FVC was calculated, and the concentrations of serum tumor necrosis factor-alpha, interleukin-6 and cardiopulmonary resuscitation were simultaneously determined using enzyme-linked immunosorbent assay. The occurrence of pulmonary complications within 7 days after operation was recorded. Results:There was no significant difference in pH values, PaCO 2, oxygenation index, peak airway pressure, plateau airway pressure, driving pressure, and dynamic lung compliance at each time point between the two groups ( P>0.05). Compared with S group, the serum Clara cell 16 kDa protein concentrations were significantly decreased at T 5, FEV 1 and FVC were increased at 3 and 7 days after operation, the serum tumor necrosis factor-alpha, interleukin-6 and cardiopulmonary resuscitation concentrations were decreased at 1, 3 and 7 days after operation, the incidence of unexpected oxygen supply and total incidence of postoperative pulmonary complications were decreased ( P<0.05), and no significant change was found in FEV 1/FVC at each time point in T group ( P>0.05). Conclusions:TEAS can improve lung function in the patients undergoing robot-assisted radical resection of colon cancer.

OBJECTIVE: The purpose of this study was to prospectively investigate the value of the myocardial extracellular volume fraction (ECV) in predicting myocardial functional outcome after revascularization of coronary chronic total occlusion (CTO). MATERIALS AND METHODS: Thirty patients with CTO underwent cardiovascular magnetic resonance (CMR) before and 6 months after revascularization. Three baseline markers of functional outcome were evaluated in the dysfunctional segments assigned to the CTO vessels: ECV, transmural extent of infarction (TEI), and unenhanced rim thickness (RIM). At the global level, the ECV values of the whole myocardium with and without a hyperenhanced region (global and remote ECV) were respectively measured. RESULTS: In per-segment analysis, ECV was superior to TEI and RIM in predicting functional recovery (area under receiver operating characteristic curve [AUC]: 0.86 vs. 0.75 and 0.73, all p values < 0.010), and it emerged as the only independent predictor of regional functional outcome (odds ratio [OR] = 0.83, 95% confidence interval [CI]: 0.77–0.89; p < 0.001) independent of collateral circulation. In per-patient analysis, global baseline ECV was indicative of ejection fraction (EF) at the follow-up examination (β = −0.61, p < 0.001) and changes in EF (β = −0.57, p = 0.001) in multivariate regression analysis. A patient with global baseline ECV less than 30.0% (AUC, 0.93; sensitivity 94%, specificity 80%) was more likely to demonstrate significant EF improvement (OR: 0.38; 95% CI: 0.17–0.85; p = 0.019). CONCLUSION: Extracellular volume fraction obtained by CMR may provide incremental value for the prediction of functional recovery both at the segmental and global levels in CTO patients, and may facilitate the identification of patients who can benefit from revascularization.
