ABSTRACT
The application of "standardized patient" in clinical teaching of our country has the irreplaceable function, but it is still unavoidably challenged by ethics. From two aspects of medical ethics and teaching ethics, this paper puts forward the ethical basis for the justification of standardized patient application. And in order to ensure that the legitimate interests of standardized patients are not infringed, clinical teachers applying standardized patients must follow the principles of respect, protection of privacy and ethical supervision. Only in a legal and reasonable vision, can we promote the orderly development of standardized patients, and provide services for more doctors, medical students and patients.
ABSTRACT
Fall efficacy is an important index reflecting the confidence and belief degree of individuals who do not fall in daily activities. Parkinson disease is a common neurodegenerative disease. Due to the deterioration of balance and other functions, the overall fall efficacy level is generally poor, which not only restricts the daily social interaction, but also further degrades the body function, and ultimately leads to the patients′ falling more easily, increased disability and decreased overall quality of life. This paper reviewed the concept, measurement tools, research status, influencing factors and intervention of fall efficacy in patients with Parkinson disease, and pointed out the existing problems and future directions, aiming to provide reference for further research on fall efficacy in patients with Parkinson disease in China.
ABSTRACT
Objective:To investigate the effect of deescalation noninvasive positive pressure ventilation in the removal of endotracheal intubation in patients with Stanford type A aortic dissection (AAD) complicated with obesity.Methods:A total of 80 obese patients with AAD from March 2018 to January 2020 in the First Affiliated Hospital of Xi′an Jiaotong University were divided into experimental group and control group with 40 cases in each group by random number table method.

ABSTRACT
In order to create a high-quality online course of Medical Ethics, this research group retrieved 16 domestic MOOC platforms in order to understand the current status of the online course construction of Medical Ethicsin Chinese universities before the outbreak of epidemic. The survey results showed that 12 teaching teams from 11 universities have built the Medical EthicsMOOC on 8 network platforms. These 12 online courses have not only played an important role in the teaching of this course during the epidemic, but also would provide valuable experience for leading Chinese universities in the online learning and teaching reform of Medical Ethics. Finally, there are three suggestions for the current problems about online teaching of medical education: firstly, increase network speed and reduce network traffic charges; secondly, utilize virtual space to make up for the lack of real space; thirdly, set up cross-professional, interdisciplinary and trans-school's compound golden courses teaching teams.
ABSTRACT
Objective To observe the incidence of spinal cord injury (SCI) following aortic surgery in Fuwai Hospital of Chinese Academy of Medical Sciences, and evaluate the effect of standardized multidisciplinary spinal cord protection strategies, to summarize the experience in the prevention and treatment of SCI at perioperative period of aortic surgery. Methods The clinical data of patients underwent aortic surgery admitted to vascular center of Fuwai Hospital from January 2011 to December 2018 were retrospectively analyzed. The patients receiving traditional spinal cord protection strategies from January 2011 to December 2016 were defined as the control group, while the patients receiving standardized multidisciplinary spinal cord protection strategies from January 2017 to December 2018 were defined as the standardized treatment group. The standardized multidisciplinary treatment included preoperative cerebrospinal fluid drainage (CSFD), respiratory tract management, and maintenance of effective circulation of the lowest venous pressure; at the same time, anticoagulation, glucocorticoid, improve microcirculation, scavenge oxygen free radicals and other adjuvant treatments were started, and nerve function was monitored to prevent complications. The changes in SCI incidence after aortic surgery between the two groups were observed in order to evaluate the effect of standardized multidisciplinary spinal cord protection strategies. Meanwhile, the types of SCI after operation and the safety of CSFD were analyzed. Results During the 8-year period, 7 724 patients underwent aortic surgery at vascular center of Fuwai Hospital, 64 of which suffered from SCI after aortic surgery with total incidence of 0.83%. The onset of SCI was immediate in 39 patients (60.94%) and was delayed in 25 patients (39.06%), more than half of patients were immediate SCI. Of 64 patients with SCI, 52 patients (81.25%) underwent paraplegia and 12 (18.75%) underwent paraparesis. SCI persisted beyond discharge in 38 patients (59.38%) and 25 patients (39.06%) fully or partly recovered form SCI. One patient (1.56%) died. Compared with the control group, the incidence of SCI was decreased significantly after application of standardized multidisciplinary spinal cord protection strategies. The total incidence of SCI after aortic surgery was decreased from 1.06% (52/4 893) to 0.42% (12/2 831), the incidence after aortic arch replacement under deep hypothermic circulatory arrest was decreased from 3.66% (40/1 092) to 1.11% (5/450), and the incidence after thoraco-abdominal aortic replacement was decreased from 9.40% (11/117) to 2.47% (2/81) with statistically significant difference (all P < 0.05). Perioperative CSFD analysis showed that the incidence of CSFD-related complications was low, the overall incidence was 5.45% (3/55), including 1 patient of cerebrospinal fluid leakage, 2 patients of blood cerebrospinal fluid. No serious complications such as hemorrhage and infection of central nervous system occurred. Conclusions The main type of SCI after aortic surgery was immediate, about 39% SCI patients fully or partly recovered. Standardized multidisciplinary spinal cord protection strategies which included preoperative CSFD, reduced incidence of SCI after aortic surgery. The incidence of CSFD-related complications was low, which was safe and effective.
ABSTRACT
Objective@#To explore the characteristics underlying Th1/Th2/Th17 expression level after entecavir (ETV) discontinuation of chronic hepatitis B (CHB) patients who were HBeAg-positive and define the role of Th1/Th2/Th17 in maintaining virological response after ETV discontinuation.@*Methods@#We selected 112 HBeAg positive CHB patients who met the withdrawal criteria according to the guideline of prevention and treatment of chronic hepatitis B (2010 version), and we also separated them into virology sustained response (SVR) group and virological relapse (VR) group according to the recurrence in 52 weeks. We detected serum level of Th1/Th2/h17 related cytokines during 0, 12, 24 and 52 weeks follow-up to further analyze their dynamic changes and expression differences.@*Results@#The results of the study reveals that serum levels of IFN-γ in the group of SVR were at a higher level compared with VR group during follow-up (all P<0.05). While, the serum level of IL-10 decreased in SVR group and was lower than the paired IL-10 level in VR group with significance during follow-up. In VR group, the serum level of IFN-γ decreased during the first 24 weeks after ETV withdrawal, and after then, the level rose. The serum levels of IFN-γ (Th1) in SVR patients were significantly higher than those in VR patients in the different follow-up time points after ETV discontinuation (all P<0.05). And the serum levels of IL-10 (Th2) in SVR patients were significantly lower than that in VR patients (all P<0.05). The comparison of serum levels of IL-17A (Th17) between the two groups had no significant difference (all P>0.005).@*Conclusions@#The serum level of IFN-γ in SVR group maintained a high level is conducive to maintaining virological response after ETV withdrawal and high level of IL-10 may be related to virologic relapse.
ABSTRACT
Objective To evaluate the clinical value of thyroid cancer gene detection and its joint diagnos-tic model in early diagnosis of thyroid nodule. Methods Retrospective study was used to analyze 61 cases of thy-roid nodules. These cases were divided into benign nodules and malignant nodules according to the pathology out-comes. We evaluated the AUC,sensitivity and specificity of preoperative fine needle aspiration biopsy(FNAB), thyroid cancer gene detection and color ultrasonography feature in the early diagnosis of thyroid nodule through lo-gistic regression analysis and ROC working curve. Results Among the 61 patients with thyroid nodules,there were 31 cases of benign thyroid nodules and 30 cases of malignant nodules.Diagnostic indexes significantly related with thyroid nodules and their AUC were listed as following:cancer gene detection 0.915(95% CI:0.814-0.971), FNAB 0.813(95% CI:0.691-0.902),low echo 0.657(95% CI:0.523-0.775),size of nodules 0.623(95% CI:0.488-0.745),joint diagnostic model respectively 0.957(95%CI:0.871-0.993). The value of joint diagnosis was the highest,whose sensitivity was 93.1% and the specificity was 90.3%.Conclusion Preoperative cancer gene de-tection joint FNAB and color ultra-sonography will improve the detection rate of thyroid cancer and reduce unneces-sary operation.
ABSTRACT
Objective: To analyze the values of combined detection of urinary micro albumin [mAlb], alpha1?microglobulin [alpha1-MG] and N-acetyl-beta-D-glucosaminidase [NAG] in the early diagnosis of diabetic nephropathy [DN]
Methods: Ninety-four patients with early DN who were admitted to the hospital between April 2015 and April 2016 were selected and set as a DN group. Moreover, seventy-six patients with diabetes who were admitted to the hospital in the same period were selected and set as a diabetes group, and sixty-four healthy people were selected as set as a control group. The urinary mAlb, alpha1-MG and NAG of the three groups were detected. Moreover, the patients were divided into a favorable blood glucose control group and a poor blood glucose control group according to the blood glucose control condition of the patients. The detection results of the three groups were compared and statistically analyzed
Results: The urinary mAlb, alpha1-MG and NAG levels of the DN group were significantly higher than those of the diabetes group and control group, and the differences had statistical significance [P<0.05]. The detection indicator values of the favorable blood glucose control group were much lower than those of the poor blood glucose control group, and the difference was statistically significant [P<0.05]. The positive rate of the combined detection of mAlb, alpha1-MG and NAG levels was 90.2%, which was much higher than that of single indicator [P<0.05]
Conclusion: Combined detection of urinary mAlb, alpha1-MG and NAG is sensitive in diagnosing early renal damages in DN patients
ABSTRACT
Objective To investigate the incidence and risk factors of the complications in perioperative intra-aortic balloon pump (IABP) supported cardiac surgical patients. Methods The clinical data of adult cardiac surgery patients undergoing IABP in Fuwai Hospital from January 2005 to January 2017 were enrolled. The patients were divided into complications group and no complications group. Demographic characteristics, diagnosis, perioperative clinical parameters, IABP related data, and IABP complications (including ischemia, bleeding, vascular injury and mechanical problems) were collected. The incremental risk factors of complications related IABP were analyzed by logistic regression. Results During the 12-year period, 522 patients received IABP support, with 388 male and 134 female; the mean age was (61.79±9.35) years; the complications related to IABP occurred in 25 patients, and overall complication rate was 4.79%; 87 IABP patients were dead in-hospital, the overall mortality was 16.67%, no patient died due to complications. The complications rate was higher in the female patients (40.00% vs. 24.95%), and was more in patients with age ≥ 65 years old (80.00% vs. 38.03%), more with higher body mass index [BMI (kg/m2): 25.45±13.71 vs. 22.95±3.45], diabetes mellitus (44.00% vs. 26.76%), combination treatment with extra-corporeal membranous oxygenation (ECMO: 20.00% vs. 5.03%) and prolonged IABP support time (hours: 134.4±90.3 vs. 109.8±89.1, all P < 0.05). There was no significant difference in the incidence of complications among preoperative IABP support, intra-operative IABP support and post-operative IABP support [3.30% (3/91), 5.46% (10/183), 4.84% (12/248), χ 2 =0.629, P = 0.730]. Bleeding from puncture site occurred in 14 cases (2.68%) without severe bleeding. Limb ischemia occurred in 9 cases (1.72%). One patient (0.19%) was under another surgery because of retroperitoneal hemorrhage caused by vascular injury. One patient (0.19%) was unsuccessful due to a balloon leak. It was shown by logistic regression analysis that presence of age ≥ 65 years [odds ratio (OR) = 2.320, 95% confidence interval (95%CI) = 1.011-1.806, P = 0.047], diabetes mellitus (OR = 2.281, 95%CI = 1.016-5.120, P = 0.026) and combination treatment with ECMO (OR = 4.341, 95%CI = 1.240-15.196, P = 0.040) were found to be the risk factors of complications related to IABP. Conclusions IABP complication rates are generally low. The frequent complications during IABP support is bleeding from site of catheterization and limb ischemia. When patients were treated with IABP, those with older age, diabetes mellitus and combination with ECMO should be monitored closely in order to reduce complications.

ABSTRACT
Objective To investigate the role of TRPV1 in exacerbation of gastric mucosal injury in a rat water immersion restraint stress (WIRS) model by acute postoperative pain. Methods Thirty Wistar rats were randomly divided into normal controlled group (N group, n=10), WIRS model group (WIRS group, n=10) and surgery after WIRS group (WS group, n = 10). The general extent of gastric mucosal injury was observed and assessed for gastric mucosal ulcer index (UI), intragastric pH and serum SOD/MDA ratio were measured and the expression of TRPV1 mRNA in gastric mocusal was accessed by Real-time Quantitative PCR. Immunohistochemistry was performed to detect the mean density of TRPV1. Results Compared with NC group, WIRS group showed obvious gastric mocusal injure with higher UI , lower values of intragastric pH serum SOD/MDA ratio and TRPV1 (P<0.05). The treatment with surgery after onset of WIRS significantly aggravated the gastric mucusal erosion and hemorrhage, with UI increased (P < 0.05), the value of intragastric pH, serum SOD/MDA ratio and TRPV1 further reduced (P < 0.05). Meanwhile, TRPV1 was inversely correlated with UI, and positively associated with intragastric pH and serum SOD/MDA ratio. Conclusion TRPV1 expression in gastric mocusal of AMGL model is inhibited by acute postoperative pain. TRPV1 may involve in the exacerbation of gastric mucosal injury in WIRS model by acute postoperative pain.
ABSTRACT
Objective To predict the disease progression risks of healthy rhesus ( normal) and rhesus infected with simian immunodeficiency virus ( SIV) in the stages of long-term nonprogressor ( LTNP) , normal progressor ( NP) , rapid progressor ( RP) by discriminant analysis. Methods Five-year observation was carried out in SIV infected rhesus model without any intervention. The SIV infected rhesus model at the stages of LTNP, NP, RP were selected, 10 in each group, and T lymphocyte subsets and serum parameters for spleen-deficiency syndrome and kidney-deficiency syndrome in SIV infected rhesus were compared with 5 healthy monkey having the same survival time. The influence factors of different types of disease progression were screened from T cell subsets and Chinese medical syndrome indexes, and then the discriminant equation was established to predict the risks. Results White blood cell ( WBC) count and lymphocyte ( LYM) ratio were enrolled into the discriminant equation before infection, and T4 level and Log10RNA of set point were enrolled into the discriminant equation in the platform period. The test results for the uniform rate of the established discriminant function showed that the total coincidence rate of theoretic distinguish to the actual data was 57.1% , 91.2%respectively before infection and in the platform period. Conclusion The pre-infection WBC count and LYM ratio can be used as a reference for the evaluation of different types of disease progresson, and Log10RNA and T4 level at platform phase can be used as the predicting factors of different types of disease progression risk prediction.
ABSTRACT
Objective To study the effect of APETx2 on the expression of ASIC3 APETx2 in a rat model of acute gastric mucosal lesion(AGML). Methods Twenty-four Wistar rats were randomly assigned to three groups in equal number : normal control group, water immersion restraint stress (WIRS) group, APETx2 treatment group. AGML was induced by WIRS for 6 hours, and APETx2 (25 μg/kg) was injected intraperitoneally before the onset of stress. Intragastric pH and gastric histopathological changes were measured and the expression of ASIC3 mRNA in DRG neurons projecting to rat stomach was examined by real-time PCR. Immunohistochemistry was performed to detect the localization of ASIC3. Results Compared with the normal control group, the WIRS group showed obvious gastric injury with lower values of intragastric pH and extensive expression of ASIC3 in the DRG neurons (P < 0.05). The treatment with APETx2 before the onset of WIRS significantly alleviated the gastric mucosal injury, decreased gastric acidity and reduced ASIC3 expression in DRG neurons (P < 0.05). Conclusions ASIC3 expression in DRG neurons projecting to rat stomach is strongly associated with gastric mucosal lesion and acidosis in the WIRS model. APETx2 can improve gastric acidosis and prevent the occurrence of these lesions.

ABSTRACT
Objective To investigate the effects of restraint stress (RS) in different periods on SOD and MDA of normal rat serums and mucosal tissues. Methods 32 adult male Wistar rats were randomly divided into normal control group (NC group, n=8), and restraint stress groups of 3 days, 5 days and 7 days (RS3, RS5 and RS7 groups, n=8 at each group). The comparisons were done between all the groups in terms of the general extent of gastric mucosal injury, gastric mucosal injury ulcer index (UI), water content, the activity of super oxide dismutase (SOD), and the level of malondialdehyde (MDA) in serum and mucosal. Results Compared with NC group, gastric mucosal injuries in RS group were more severe, the UI and water content was proportionally related with the restraint periods. Meanwhile, the serum and mucosal SOD in the RS groups were all increased, and with prolonged restraints, the SOD were decreased, but the serum and mucosal MDA were increased (P<0.01) and SOD/MDA in the mucosa lowered as well (P<0.01). Conclusion Restraint stress may cause mucosal injury proportional to the stress time and related with lowered SOD/MDA in mucosal tissues.
ABSTRACT
Objective To observe the protective effect of sufentanil pretreatment on the rats with acute gastric mucosa lesion (AGML) induced by water immersion and restrain stress (WIRS) and its effect on TRPV1 mRNA expression in the hypothalamus and gastric mucosa. Methods Thirty male Wistar rats were randomly designed into 3 groups, including the normal control group (Group NC, n = 10), the group treated with WRIS for 6 h (Group WIRS, n = 10) and the group pretreated with sufentanil (Group SF, n = 10). The model of AGML was established by the classic WIRS method , and observed for the general extent of gastric mucosal injury at WIRS for 6 hr, and calculated gastric mucosal injury ulcer index (UI) and the PH value of gastric juice; The quantification of TRPV1 mRNA expression in hypothalamus and gastric mucosa was performed using quantitative real-time PCR; In addition, the activity of super oxide dismutase (SOD) and the level of malondialdehyde (MDA) in serum were detected. Results Compared with group NC, gastric mucosal in Group WIRS was injured more seriously , and the UI and the activity of MDA were also obviously increased , but the change of SOD activity was not apparent; The TRPV1 expression in gastric mucosal decreased apparently. Sufentanil pretreatment could effectively relieve gastric mucosal injury induced by WIRS , and make the UI and the activity of MDA decreased , and up-regulate TRPV1 mRNA expression in the hypothalamus and gastric mucosa. Conclusions Sufentanil pretreatment can effectively relieve AGML induced by WIRS , which may be related to the control of oxidative stress response , the reduced gastric acid secretion , and the upregulation of the TRPV1 mRNA expression in the central and periphera nerve.
