Objective:To evaluate the effect of thoracic paravertebral block (TPVB) combined with general anesthesia on the postoperative brain injury in elderly patients undergoing thoracoscopic radical resection of lung cancer.Methods:A total of 100 patients of either sex, aged ≥65 yr, with body mass index of 20-24 kg/m 2, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, scheduled for elective thoracoscopic radical resection of lung cancer, were divided into 2 groups ( n=50 each) by using a random number table method: general anesthesia group (G group) and TPVB combined with general anesthesia group (TG group). TPVB was performed before induction of anesthesia in group TG.Anesthesia was induced with IV midazolam, etomidate, rocuronium and sufentanil and maintained with infusion of propofol and remifentanil and intermittent IV boluses of cis-atracurium.Patient-controlled intravenous analgesia (PCIA) was used for postoperative analgesia after surgery.Venous blood samples were taken at 5 min after entering the operating room and 24 and 72 h after surgery to determine the concentrations of S100β, neuron-specific enolase, Tau protein, β amyloid and interleukin-6 in plasma.The cognitive function was assessed by using the Mini Mental State Examination Scale and Montreal Cognitive Assessment Scale at 1 day before surgery and 24 and 72 h after surgery, and cognitive dysfunction was recorded.The quality of night sleep was assessed using Numerical Rating Scale at 1 day before surgery, on the day of surgery and on day 3 after surgery.The occurrence of nausea and vomiting within 72 h after operation, perioperative consumption of sufentanil, effective pressing times of PCA within 24 h after operation and requirement for postoperative rescue analgesia were recorded. Results:No postoperative nausea and vomiting was found and no patients required rescue analgesia in either group.Compared with group G, the concentrations of S100β, neuron-specific enolase and interleukin-6 in plasma, Montreal Cognitive Assessment scale score, and incidence of cognitive dysfunction were significantly decreased at 24 h after surgery, sleep quality score was increased, and the perioperative sufentanil consumption and effective pressing times of PCA were reduced ( P<0.05), and no significant change was found in plasma Tau protein and β amyloid concentrations in group TG ( P>0.05). Conclusions:TPVB combined with general anesthesia is helpful in reducing postoperative brain injury in elderly patients undergoing thoracoscopic radical resection of lung cancer.

Objective To explore comprehensive nursing measures to the high-risk patients with cerebral apoplexy in nursing outpatient and evaluate the effect.Methods Convenience sampling method was used to select 75 high-risk cerebral apoplexy patients in the nursing outpatient from April 201 4 to December 201 4,patients were carried out comprehensive nursing measures including measuring blood pressure,body weight,and abdominal circumference,instructing to take medication correctly and establish a healthy physical exercise and diet style.Results After 6 months of intervention,systolic blood pressure and diastolic blood pressure of the subjects decreased from (1 48.40 ±1 3.86)mmHg to (1 33.1 ±1 2.49)mmHg and (84.75 ± 8.50)mmHg to (79.75 ±7.40)mmHg respectively(P <0.05).Before and after intervention,the reasonable exercise rate rose from 41 .3% to 72.9%,smoking rate decreased from 53.3% to 21 .4%,compliance with medication rose from 52.0% to 85.7%,salty diet rate decreased from 56.0% to 37.1 %,oiled diet rate decreased from 69.3% to 1 5.7%,compliance with fruit intake rose from 38.7% to 90.0%,compliance with milk drink rose from 30.7% to 75.7%(P <0.05).Conclusions Outpatient comprehensive stoke intervention measures to patients with high-risk for cerebral apoplexy can reduce the risk factors to stoke,improve lifestyle and provide basis for stoke high-risk population.

OBJECTIVE To construct the simulated traditional Chinese medicine pharmacy based on virtual simulation technology， and assist in the development of the new mode of traditional Chinese medicine dispensing education training. METHODS The field research and questionnaire surveys were conducted to identify the needs of Chinese medicine students and practitioners for the content and presentation of knowledge on the construction of simulated traditional Chinese medicine pharmacy. Taking the laws and regulations on the construction of traditional Chinese medicine pharmacy and the related teaching materials and literature on traditional Chinese medicine preparation as the knowledge source， the virtual simulation technology was applied to build a simulated traditional Chinese medicine pharmacy so as to achieve the functions of browsing the traditional Chinese medicine pharmacy， learning the knowledge of traditional Chinese medicine preparation and practical skills training. A multi-site simulated traditional Chinese medicine pharmacy evaluation scale study was conducted based on platform operational testing. RESULTS A simulated traditional Chinese medicine pharmacy was constructed， consisting of four core modules： video teaching， animation video， simulated pharmacy， and simulated experience. The overall score of evaluation scale was 93.31， with all entries scoring above 80； the ones with evaluation scales above 90 accounted for 92.31% （60/65）. CONCLUSIONS Simulated traditional Chinese medicine pharmacy based on virtual simulation technology meets the learning needs of users and enhances the teaching effect of traditional Chinese medicine dispensing technology training.
