Exposure to thermal environment is one of the main concerns for manned space exploration. By focusing on the works performed on thermoregulation at microgravity or simulated microgravity, we endeavored to review the investigation on space thermal environmental physiology. First of all, the application of medical requirements for the crew module design from normal thermal comfort to accidental thermal emergencies in a space craft will be addressed. Then, alterations in the autonomic and behavioral temperature regulation caused by the effect of weightlessness both in space flight and its simulation on the ground are also discussed. Furthermore, countermeasures like exercise training, simulated natural ventilation, encouraged drink, etc., in the protection of thermoregulation during space flight is presented. Finally, the challenge of space thermal environment physiology faced in the future is figured out.

Objective To observe the efficacy of combinated inhaled glucocorticosteroid and long- ?2 - agonist for asthmatic children. Methods Forty- seven children with moderate or severe persistent asthma were treated with inhalation of the fluticasone pro-pionate and salmeterol. The PEF value and the mark according the symptom of asthma before and after treatment( week and month respectively) were recorded. At the same time the days of treatment the patient with the short - ?2 - agonist in the first week and the forth week respectively were noted. The subjective feeling and accident of patients also should be paid attention. Results There was significant difference (P

Objective To evaluate the efficacy of naloxone used in the postoperation of cerebral tumor.Methods Eighty patients were randomly assigned to receive (treated group:40 patients) or not re- ceive (control group:40 patients) naloxone.Both the two groups accepted the conventional therapy.Re- sults After operation,the content of?-EP,ET decreased continuously but the one of the treated groups was more obviously than that of the control groups (P

Objective To analyze the effect of clinical pharmacists involving in JCI clinical care program certification-AMI(CCPC-AMI) on the compliance rates of clinical drug treatment guideline and the awareness rates of patient medication health education in cardiovascular.Methods Selected cases of acute myocardial infarction(AMI) from March to August in 2015 was as the former group,from September 2015 to March 2016 as the latter group in their hospital,then comparative analysis of two groups was done by statistical method.Results After clinical pharmacists involved in CCPC-AMI,the compliance rates of AMI clinical drug treatment guidelines (after the AMI diagnosis, the 10min was given aspirin, intensified statin therapy and dose selection, the use of ACEI/ARB before discharge and the use of beta blocker before discharge) were increased from 92.7% 67.9%,60.7%,51.8% to 98.1%,85.2%,94.4%,90.7%.The awareness rates of patient medication health education (awareness of safe medication, awareness of self-management, awareness of follow-up knowledge) were all increased to 100% from 75.0%,57.1%,82.1% before participation.Conclusion Clinical pharmacists who carried out pharmaceutical care,has played a critical role in quality control of AMI single disease through the preparing of CCPC-AMI evaluation.

BACKGROUND: Lower extremity deep venous thrombosis is commonly seen after hip arthroplasty. The time of thrombosis after arthroplasty in senile patients with osteoporotic femoral neck fractures is little reported.OBJECTIVE: To investigate the time of perioperative lower extremity deep venous thrombosis in senile patients with osteoporotic femoral neck fractures undergoing hip arthroplasty. METHODS: The data of 178 patients with femoral neck fractures undergoing hip arthroplasty were analyzed, and were then allocated to anticoagulant and non-anticoagulant groups according to the preoperative use of low-molecular-weight heparins or not. Doppler ultrasonography of both lower extremity arteries was conducted at 1, 3, 5 and 5-7 days after injury, and 2, 5, 7 and 14 days postoperatively to monitor the lower extremity deep venous thrombosis, and the number and incidence of thrombosis in the two groups were recorded at different time points. The time of thrombosis occurred frequently after injury and surgery was determined through drawing the frequency distribution table and line chart.RESULTS AND CONCLUSION: (1) The incidence of thrombosis showed significant difference between anticoagulant (n=6, 8%) and non-anticoagulant (n=22, 21%)) groups (P < 0.05). (2) Thrombosis frequently occurred at 3 days after injury and 1 day postoperatively. (3) These results suggest that the thrombosis in patients with femoral neck fractures frequently occurs at 1-3 days after injury and 1 day after replacement. Additionally, active prevention measures after injury can significantly reduce the incidence of lower extremity venous thrombosis.

Objective To explore how to prevent biliary duct injury during laparoscopic cholecystectomy.Methods The clinical data of 484 cases of laparoscopic cholecystectomy from December 2002 to December 2007 were retrospectively analyzed,and the experiences of preventing biliary duct injury were summarized.Results No biliary duct injury case was found but 26 cases were converted to laparotomy during operation and 20 cases were placed drainage tube.Conclusion Familiar with the anatomy of bile duct,careful handling of the Calot's triangle are the keys to prevent biliary duct injury in LC.

Objective To compare the efficacy of laryngeal mask airway-Advance (ALMA) and laryngeal mask airway-Supreme (S-LMA) in patients undergoing laparoscopic cholecystectomy.Methods Two hundred and forty ASA Ⅰ or Ⅱ patients,aged 18-64 yr,weighing 50-70 kg,undergoing laparoscopic cholecystectomy,were randomly divided into2 groups (n=120 each):group S-LMA (group S) and group A-LMA (group A).LMA was inserted after induction of general anesthesia with propofol 2.0-2.5 mg/kg,sufentanil 0.2 μg/kg and rocuronium 0.6 mg/kg.After LMA was placed,the rim was immediately inflated and positive pressure was applied to the reservoir bag of anesthesia machine circuit to check for leaks.The plateau pressure at which leaks occurred was recorded.BP,HR,SpO2,PErCO2 and Ppeak were monitored during operation.Fiberoptic bronchoscopy was performed and the placement was scored (0 =unable to see the vocal cords and the ventilation of the lungs was inadequate,4=vocal cords were clearly seen and ventilation was adequate).The rate of successful placement,placement time,the incidence of leaks during operation,duration of anesthesia and surgery,extubation time,emergence time,blood stain on the LMA after being removed,backflow after extubation and postoperatve complacations including sore throat,hoarseness and dysphagia were recorded.The efficacy for airway management and the difficulty of placement were scored.Results There was no significant difference in the rate of successful placement,difficulty of placement scores,blood stain on the LMA after being removed,incidence of backflow,sore throat,hoarseness and dysphogia,anesthesia time,duration of surgery,extubation time and emergence time between the two groups.The placement time was shorter in group S than in group A,but the airway sealing pressure,FOB scores and efficacy for airway management scores were significantly higher and the incidence of leaks during operation was significantly lower in group A than in group S.Conclusion Both A-LMA and S-LMA can provide adequate ventilation during laparoscopic cholecystectomy.The efficacy of A-LMA is better.
