Objective To analyze the characteristics of change in plasma cholesterol level in patients with sepsis, and to explore its relationship with prognosis and its clinical significance. Methods A retrospective analysis was conducted. 568 patients with sepsis admitted to Department of Critical Care Medicine of Beijing Friendship Hospital Affiliated to Capital Medical University from August 2013 to August 2015 were enrolled, and 475 patients without sepsis hospitalized in the same period served as the control. The basic clinical data of the two groups were collected, and the results of blood fat and biochemical parameters were compared. The patients with sepsis were divided into death group and survival group, and risk factors influencing the prognosis of patients with sepsis were analyzed with multivariate logistic model regression analysis. Results Compared with non-sepsis patients, the levels of plasma total cholesterol (TC) and high density lipoprotein cholesterol (HDL-C) in the patients with sepsis were significantly lower [TC (mmol/L): 2.5±1.2 vs. 3.4±1.4, t = 4.274, P = 0.021; HDL-C (mmol/L): 1.6±0.9 vs. 2.5±0.8, t = 3.413, P = 0.018], and that of low density lipoprotein cholesterol (LDL-C) showed no statistically significant difference (mmol/L: 1.9±0.9 vs. 2.1±0.9, t = 0.749, P = 0.614). In the patients with sepsis, the patients in death group (n = 227) were older than those of the survival group (n = 341, years: 74.3±15.5 vs. 65.5±17.5, t = 4.037, P = 0.012), serum creatinine (SCr) was higher than that of survival group (μmol/L: 251.0±115.6 vs. 167.4±108.7, t = 3.254, P = 0.023), the levels of plasma TC, HDL-C and LDL-C were significantly lower than those of survival group [TC (mmol/L): 2.2±1.6 vs. 2.9±1.1, t = 3.057, P = 0.023; HDL-C (mmol/L): 1.4±0.8 vs. 1.9±0.8, t = 4.692, P = 0.016; LDL-C (mmol/L): 1.7±0.7 vs. 2.0±0.8, t = 2.541, P = 0.038]; there was no significant difference in the proportion of male, body mass index (BMI), based disease, intensive care unit (ICU) hospitalization time, the severity of the disease and other biochemical indexes between two groups. With single factor analysis with indicators of statistical significance as a covariate into binary logistic regression equation, the results show that age was the risk factor of death in patients with sepsis [odds ratio (OR) = 1.024, 95% confidence interval (95%CI) = 1.010-1.048, P = 0.009], and TC was the protective factor on the prognosis of patients with sepsis (OR = 0.747, 95%CI = 0.682-0.811, P = 0.013). Conclusions Plasma cholesterol levels in patients with sepsis were significantly lowered, and the levels in death group was significantly lower than that in the survival group. TC may be used as a clinical indicator to assess the outcome of patients with sepsis.

Objective? To investigate the feasibility and safety of vacuum modelling pad for patients with lateral position in thoracic surgery to improve the convenience and comfortable experience for medical staff and patients. Methods? From May 2017 to March 2018, 100 patients who underwent thoracic surgery under general anesthesia with lateral position in the operating room of Sun Yat-sen University Cancer Center were randomly selected and divided into observation group(n=50) and control group (n=50) according to random number table. The polyurethane vacuum modelling pad was used for to secure the patients' position in the observation group, while the sand bag baffle was used to secure the patient's position in the control group. Position placement time and skin pressure blisters were recorded in both groups. Questionnaires were sent out after operation to collect the satisfaction of medical staff with this position. The patients' comfort was followed up within 24 hours after operation. Results? The position placement time in the observation group was (183.56±10.36) s, shorter than the control group with (290.80±14.71)s and the difference was statistically significant(P＜ 0.01); there were 11 cases of skin reddening under pressure and 2 cases of blister in the observation group, which is statistically different from the control group with 24 cases of skin reddening under pressure and 9 cases of blister(P＜ 0.05). Patients' comfort score was(6.72±0.39) in the observation group, higher than the control group with (6.02±0.44) and the difference was statistically significant(P＜ 0.01). In terms of the 4 items of "the convenient operation", "comfortable standing position", "patient safety" and"overall evaluation", the observation group scored higher than the control group with statistical differences (P＜0.01); in terms of the "surgical field exposure" and "fasten effects", there was no statistical difference (P＞0.05). Conclusions? The use of modelling pad for patient lateral position in thoracic surgery can not only prevent organ and skin damage and ensure patient safety, but also simplify the operation procedure, improve the comfort of standing position and the working efficiency and satisfaction of the medical staff.

Objective To investigate the effect of radial artery hemostat (TR Band) continuous compression time on bleeding of puncture point, thumb perception, palm swelling and subjective comfort in patients undergoing transradial percutaneous coronary intervention. Methods One hundred and fifty-five patients who underwent transradial percutaneous coronary intervention were randomly divided into two observation groups and a control group. All patients in the three groups were treated by TR Band patent hemostasis. All three groups received the consistent deflation schedule, except the TR Band was removed at the 12th hour post operation in the control group, and at the 6th hour in the 1st observation group and at the 4th hour in the 2nd observation group. Postoperative bleeding of puncture point, thumb perception, palm swelling and subjective comfort were observed in the three groups. Results The differences of postoperative bleeding of puncture point, thumb perception, palm swelling and subjective comfort among the three groups were statistically significant (χ2=6.31, P<0.05; F=5.26, 4.00, 14.69, P<0.01). In the 2nd observation group, palm swelling was the lowest, but perception, and comfort and bleeding rate is the highest among the three groups. In the 1st observation group, the overall indexes were medium among the three groups. Conclusions The optimal compression duration of TR Band post transradial percutaneous coronary intervention is 6 h, which does not increase the risk of bleeding, but also significantly improve local swelling and perceptual experience, and increase patient comfort.

A small HIFU system was used to investigate the phase-shift droplet vaporization in vivo and its effect on thermal absorption in tissue-mimicking phantoms. The experiments demonstrated that droplets could be vaporized to bubbles in vivo by the small HIFU system and the volume of bubbles could increase by tens of times. With appropriate droplets concentration, lesion volume produced by HIFU could be increased significantly under the same HIFU parameter.
