Objective:To explore the prevention effect of forced-air warming to the upper body on hypothermia during thoracoscopic surgery in the lateral decubitus position.Methods:A total of 82 patients undergoing thoracoscopic surgery in the lateral position from December 2018 to July 2019 in Jiangsu People's Hospital, the First Affiliated Hospital of Nanjing Medical University were divided into upper body group and lower body group according to the random number table method. Each group was 41 cases. Patients received forced-air warming on the upper body or lower body in the upper body group and lower body group, respectively. The bladder temperature was measured as core temperature at operation room, intubation, start of the surgery, 30 min after surgery, 60 min after surgery, 90 min after surgery, 120 min after surgery, end of the surgery. The incidence of intraoperative hypothermia, perioperative adverse complications and vital index at leaving the room were compared between upper body group and lower body group.Results:The core temperature at start of the surgery, 30 min after surgery, 60 min after surgery, 90 min after surgery were (36.70±0.12), (36.65±0.16), (36.30±0.18), (36.32±0.19) ℃ in the upper body group, and (36.42±0.13), (36.32±0.17), (36.17±0.14), (36.21±0.15)℃ in the lower body group, the differences were statistically significant ( t values were 2.743-10.362, P<0.05). However, there was no statistically significant in the core temperature at other time points between the two groups ( P>0.05). The incidences of intraoperative hypothermia and perioperative shiver were 12.2%(5/41), 4.9%(2/41) in the upper body group, and 31.7%(13/41), 21.9%(9/41) in the lower body group, the differences were statistically significant ( χ2 values were 4.556, 5.145, P<0.05). There was no statistically significant in the other perioperative adverse complications and vital index at leaving the room between two groups ( P>0.05). Conclusions:Forced-air warming was more effective on the upper body in resistive body core temperature. Besides, the incidences of hypothermia and shiver on the upper body is lower.

Objective To evaluate the accuracy of ultrasonographic measurement of the transverse diameter of the cricoid cartilage in selecting the cuffed endotracheal tube (ETT) size for pediatric patients.Methods A total of 120 pediatric patients of both sexes,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,aged 1 month-6 yr,with body mass index of 10.9-31.2 kg/m2,undergoing endotracheal intubation and general anesthesia,were divided into group A and group B,with 60 pediatric patients in each group.The pediatric patients were intubated with a cuffed ETT in two groups.The ETT size was selected based on the transverse diameter of the cricoid cartilage measured by ultrasonography in group A.The ETT size was selected according to the age-based formula in group B.A tracheal leak was detected after intubation to determine whether or not the ETT size selected was appropriate.ETTs were replaced when the actually selected ones were not appropriate,and the number of replacement was recorded.The development of intubation-related complications was also recorded.Results The accurate rate of cuffed ETT size selected at the first time was 95% in group A,and it was significantly higher than that in group B (60%) (P< 0.05).There was no significant difference in the incidence of intubation-related complications between the two groups (P>0.05).Conclusion Uhrasonographic measurement of the transverse diameter of the cricoid cartilage produces higher accuracy in selecting the cuffed ETT size for pediatric patients and is worthy of clinical application.

OBJECTIVE:To optimize the formulation optimization of Nicorandil sustained-release matrix tablet,and evaluate its drug release properties in vitro. METHODS:Based on single factor test,powder direct compression method was used,using nicorandil cumulative release rate (Q) in 1,4,8,12 h as evaluation indexes,central composite design-response surface method was adopted to optimize the amount of hydroxypropyl methylcellulose(HPMC)and ethyl cellulose(EC);Q values within 12 h in different pH (1.0,5.0,6.8,7.4) media were compared. RESULTS:The optimized formulation (every tablet) was nicorandil 10 mg,HPMC 150 mg,EC 90 mg,microcrystalline cellulose 80 mg,lactose 60 mg,magnesium stearate 2%. Q1 h,Q4 h,Q8 h and Q12 h of the obtained formulation were 23.6%,51.3%,83.7% and 96.9%,respectively;deviation from the predicted values were 2.1%,1.6%,1.0%,0.2%. Q values were similar in pH 1.0-7.4 at different time points. CONCLUSIONS:The obtained Nicor-andil sustained-release matrix tablet by optimal formulation shows sustained-release effect,and the change of pH 1.0-7.4 has no in-terference in the release characteristics of main drug.

Objective To indentify the cognitive status of Chinese patients to acne and the influencing factors to theirs' cognitive status,so as to provide solid evidences for the prevention and treatment of acne.Methods A self-designed questionnaire was made to conduct this survey of 16,156 acne patients,who seeked to the treatment in the dermatological departments from 112 hospitals in China.The survey consisted of several parts,including the general status of patients,the patients' cognition of occurrence,development and risk factors of acne,whether the first choice was seeking treatment at the hospital when the patients had acne and the condition of selection of skin care products.The factors were analyzed,which could impact the cognition of the patients' behavior of treatment,how did the patients' cognition to influence their medical behavior and skin care as well as the consistency of assessment of the severity of acne by doctors and patients themselves.Results The acne patients studied had the best knowledge of "acne is a skin disease","it not only occurs in the period of adolescence" and "the disease can be prevented and cured",which accordingly accounted for 80.65%,69.16% and 65.49% of the total patients respectively.However,the awareness of acne patients to heredity,high sugar and dairy products as risk factors for acne was insufficient,which accounted for 48.72%,42.40% and 18.25% of the total patients,respectively.Gender,age,educational level,occupation and health knowledge were the main factors affecting the cognitive level of patients;the survey also found that men,patient with educational level of junior high or even lower educational condition,occupation of labor workers or farmers and patients were lack of health education with poor knowledge of the genetics and dietary were risk factors for acne;patients with age over 36 years or with mild illness had poor knowledge of dietary risk factors for acne;the difference was statistically significant (P<0.05).The analysis of the influence of cognitive status on medical treatment behavior and skin care showed that the better the cognition,the higher the probability of patients would choose medical treatment as the first choice as well as choosing functional skin care products;the difference was statistically significant (P<0.05).The consistency of assessment of the severity of acne by doctors and patients was poor (Kappa value <0.4),and the assessment of severity of acne by patients was more serious than doctors' assessment.Conclusions Patient's cognitive status will affect their medical behavior and skin care,and there is also a phenomenon that patients have a more serious assessment of their acne condition.It is suggested that health education for acne patients should be strengthened in clinical medicine so as to improve their knowledge of acne as well as preventing from acne effectively.
