Objective:To explore the risk factors of sepsis in patients with multiple trauma and construct a nomogram prediction model.Methods:The data of patients with multiple injuries admitted to the emergency intensive care unit (EICU) of the General Hospital of Ningxia Medical University from January 2021 to April 2022 were respectively collected. Inclusion criteria: (1) meet the diagnostic criteria for multiple injuries; (2) the time from injury to admission ≤ 24 hours; (3) age>18 years old; (4) all examination or rescue measures were approved by the patient or the patient's family; (5) the patient's clinical data were complete. The patients were divided into sepsis group and non-sepsis group according to the definition of Sepsis 3.0 at the 28-day of EICU hospitalization. The receiver operating characteristic curve was drawn. Logistic regression analysis was applied to determine the independent predictors for sepsis, and the nomogram was constructed.Results:A total of 291 patients were included, including 102 in the sepsis group and 189 in the non-sepsis group. Multivariate logistic analysis revealed that age, acute physiology and chronic health status score (APACHE) Ⅱ, Glasgow Coma Scale (GCS), injury severity score (ISS), sequential organ failure assessment (SOFA) within 24 hours after admission, blood transfusion frequency, the application of norepinephrine, mechanical ventilation, pathogenic culture results, and history of diabetes were independent factors influencing the occurrence of sepsis. A nomogram model was constructed by combining these variables (AUC=0.913, 95% CI: 0.847-0.942), and the model had a good fitting calibration curve. Conclusions:The nomogram constructed by age, APACHE-Ⅱ, GCS score, SOFA score, ISS score, number of blood transfusions, mechanical ventilation, norepinephrine drug use, pathogenic culture and diabetes has a good predictive value for sepsis in patients with multiple trauma in the later stage, which is worth promoting.

Objective:To summarize the clinical features of primary segmental volvulus (PSV) in neonates.Methods:A retrospective analysis was conducted on the clinical data of neonates with PSV who were admitted to the Department of Neonatal Surgery, Children's Hospital Affiliated to Capital Institute of Pediatrics from May 2014 to May 2023. The clinical manifestations, auxiliary examinations, treatment and prognosis of the neonates were summarized, and descriptive statistical analysis was performed on the collected data.Results:A total of 10 neonates with PSV were included, with a mean gestational age of (34.1±3.0) weeks and birth weight of (2 291±646) g. Eight cases had an onset age of 3 d or less, and 2 cases had an onset age of more than 3 d. Abdominal distension was observed as the main manifestation in all cases, while bilious vomiting occurred in seven cases and hematochezia in five cases. Imaging examinations mainly revealed low intestinal obstruction without specific manifestations. Laboratory tests showed metabolic acidosis and varing degrees of anaemia. Nine cases underwent diagnostic abdominal puncture, of which five had bloody ascites, two had clear ascites, one had bloody mixed with fecal-like ascites, and one had chylous ascites. All the cases underwent emergency exploratory laparotomy and segmental small bowel resections with either primary intestinal anastomosis or enterostomy. All cases were successfully cured and had been followed up to the age of 4 months to 9 years with good growth and development as normal children of the same age.Conclusions:Neonatal PSV is an independent abdominal emergency characterized by non-specific clinical manifestations and difficult preoperative diagnosis, but the overall prognosis is favorable after active surgical treatment.

Atherosclerosis is a chronic vascular inflammatory disease caused by abnormal lipid metabolism.The formation of lipid-rich foam cells acts as the initial trigger for development of atherosclerotic lesions.Recent studies have shown that lipophagy,a form of selective autophagy,can selectively degrade lipid droplets stored intracellularly and promote cholesterol efflux through the autophagic lysosomal pathway.As a result,intracellular lipid accumulation is re-duced and foaming is inhibited,making lipophagy a potential new target for current anti-atherosclerosis therapy.This arti-cle reviews the crucial role and molecular mechanism of lipophagy in the link between lipid metabolism and atherosclero-sis.Its objective is to outline the regulatory mechanism of lipophagy and present fresh insights for the treatment of athero-sclerotic diseases.

ABSTRACT Objective: To investigate the risk factors for predicting atrial high-rate episodes (AHREs) detected by cardiac implantable electronic devices (CIEDs). Methods: A total of 140 patients with CIED in our hospital from June 2013 to June 2018 were included and were followed up to observe whether they had AHREs. AHRE are defined as atrial rate ≥ 175 times/minute, lasting > 5 minutes, and reviewed by an experienced electrophysiologist with unclear clinical diagnosis. The patients fasted for 12 hours after implantation, and blood samples were collected for biochemical, lipid, and whole blood count detection. Follow-up was regular after discharge to record follow-up data of each patient and conduct statistical analysis. Results: One hundred and forty patients were implanted with dual-chamber pacemakers, their median age was 70 years old, 44.29% were male, 27 patients had AHRE within one year, and AHRE incidence rate was 19.29%. The microcytic to hypochromic (M/H) ratio was calculated for all AHRE patients and compared with the patients without AHRE; the M/H value of AHRE patients was significantly higher. Throughout the entire follow-up period, a total of 44 patients developed AHRE; when adjusted by multivariate analysis, only M/H ratio ≥ 4.5 vs. < 4.5 had statistical significance, and the adjusted hazard ratio value was 4.313 (1.675-11.105). Conclusion: As an indicator, M/H ratio may play an important role in the occurrence and development of atrial fibrillation and can be used as a predictor of AHRE in patients with CIED.

Objective:To explore the prognostic risk factors of patients with multiple injuries and establish a nomogram prediction model.Methods:The clinical data of 291 patients with multiple injuries admitted to the Emergency Intensive Care Unit (EICU) of General Hospital of Ningxia Medical University were collected, including sex, age, open injury, norepinephrine use, mechanical ventilation, time to hospital after injury, distance to hospital, relative lymphocyte value, platelet count, lactic acid, injury severity score (ISS), acute physiology and chronic health evaluationⅡ (APACHE Ⅱ), Glasgow coma scale (GCS), number of blood transfusions, number of operations, and previous history of diabetes, hypertension and smoking within 24 h after admission. According to whether the condition worsened during the hospitalization of EICU, the patients were divided into the deterioration group and improvement group. SPSS26.0 software was used for statistical analysis of the data, univariate and multivariate analysis were used to screen the factors affecting the prognosis of patients with multiple injuries, receiver operating characteristic (ROC) curve and forest chart were drawn, and the influencing factors in binary Logistic regression model were used to make the nomogram.Results:Mechanical ventilation, norepinephrine use, age, relative lymphocyte value, lactic acid, APACHE-II score, GCS score, and number of operations were significant for predicting the prognosis of patients with multiple injuries ( P<0.05). The independent influencing factors obtained by binary Logistic regression model were age, lactic acid, APACHE-Ⅱ score and number of operations. ROC curve analysis showed that the area under the curve was the largest in multi-factor combined prediction, followed by APACHE-Ⅱ score. The diagnostic cut-off value of each index was as follows: age >58 years old, relative lymphocyte value≤ 8.62%, lactic acid >1.72, APACHE-Ⅱ score >16, GCS score≤ 6, and number of operations≤ 0. The R software was used to establish a nomogram of the influencing factors in the binary Logistic regression model, which had good predictive value. Conclusions:The nomogram constructed by age, relative lymphocyte value, lactic acid, APACHE-Ⅱ score, GCS score, number of operations, mechanical ventilation, and norepinephrine use has a good predictive value for the prognosis of patients with multiple injuries, and is worthy of promotion..

Objective:To investigate the treatment of preterm and low birth weight infants with congenital diaphragmatic hernia (CDH) and to share the experience.Methods:This retrospective study enrolled 117 newborns with CDH who underwent major surgery at Children's Hospital, Capital Institute of Pediatrics from May 1, 2011, to March 31, 2022. Based on gestational age and birth weight, the infants were divided into the preterm and/or low birth weight group (gestational age < 37 weeks and/or birth weight less than 2 500 g, n=41) and the control group (gestational age ≥ 37 weeks and birth weight ≥ 2 500 g, n=76). Furthermore, the preterm and/or low birth weight infants were divided into the thoracoscopic surgery subgroup ( n=31) and the open surgery subgroup ( n=10) according to the surgical approach. Statistical analysis of the data was performed using two independent sample t-tests, rank sum tests, Chi-square test, or Fisher's exact probability test. Results:Preoperative data showed that the Apgar scores at 1 min [7.0 (6.0-8.0) vs 9.0 (8.0-9.8), Z=－4.03] and 5 min [9.0 (8.0-10.0) vs 9.0 (9.0-10.0), Z=－2.13] of the preterm and/or low birth weight infants were both lower than those in the control group (both P<0.05), while the proportion of infants with moderate to severe pulmonary hypertension was higher [68.3% (28/41) vs 38.2% (29/76), χ 2=9.68, P<0.05]. There were no statistically significant differences between the two groups in terms of the proportion of thoracoscopic surgery, operation time, right diaphragmatic hernia, presence of hernia sac, grading of the defect, presence of liver herniation, and application of mesh (all P>0.05). Regarding the postoperative outcomes, the death rate in the preterm and/or low birth weiht group was higher compared to the control group [36.6% (15/41) vs 13.2% (10/76), χ 2=8.70, P<0.05]. Additionally, the time required to resume full enteral nutrition after surgery was longer in the preterm and/or low birth weight group than that in the control group [25 d (18-29 d) vs 16 d (10-25 d), Z=2.31, P<0.05]. The thoracoscopic subgroup had a lower mortality compared to the open surgery subgroup [25.8% (8/31) vs 7/10, P<0.05]. The thoracoscopic surgery subgroup had a higher Apgar score at 1 min after birth [(7.4±1.6) vs (6.0±2.2), t=2.20, P<0.05], later age at operation (hours after birth) [31.0 h (23.0-48.0 h) vs 17.0 h (4.7-24.5 h), Z=2.57, P<0.05], a lower proportion of infants operated within 24 hours after birth [32.3% (10/31) vs 8/10, P<0.05], and longer duration of operation [170.0 min (122.0-200.0 min) vs 110.0 min (87.3-120.0 min), Z=3.65, P<0.05]. Conclusions:In this study, a higher mortality in the preterm and/or low birth weight group compared to the control group was observed, which may be attributed to the higher proportion of neonates with moderate-severe pulmonary hypertension. The thoracoscopic diaphragmatic repair can be attempted for preterm and low birth weight infants who have relatively stable respiratory and circulatory functions.

The localized CT images and target organs at risk and other structural data were collected. Two radiotherapy plans, VMAT and TD, were designed for the same patient, and the dosimetry differences of target areas and organs at risk were compared and analyzed between the two groups.Results:In terms of target dosimetry, there were statistically significant differences in the D 2% [ (59.99±0.19) Gy vs. (59.55±0.51) Gy, t=4.09, P<0.001], D 98% [ (57.19±0.08) Gy vs. (57.46±0.22) Gy, t=-5.10, P<0.001], conformal index (CI) (0.76±0.05 vs. 0.58±0.13, t=8.19, P<0.001) and homogeneity index (HI) (0.05±0.00 vs. 0.04±0.01, t=4.89, P<0.001) of the planning gross tumor volume (PGTV) between VMAT and TD plans. However, there was no statistically significant difference in the D 50% [ (58.73±0.10) Gy vs. (58.73±0.24) Gy, t=-0.03, P=0.974]. There were statistically significant differences in the D 50% [ (52.21±0.33) Gy vs. (53.00±0.72) Gy, t=-4.81, P<0.001], D 98% [ (48.44±0.43) Gy vs. (49.09±0.21) Gy, t=-6.80, P<0.001], CI (0.83±0.06 vs. 0.67±0.06, t=10.52, P<0.001) and HI (0.20±0.01 vs. 0.19±0.01, t=8.75, P<0.001) of the planned target volume (PTV) between the two plans. However, there was no statistically significant difference in the D 2% [ (59.01±0.45) Gy vs. (59.00±0.48) Gy, t=0.22, P=0.830]. In terms of organs at risk, there were statistically significant differences in the V 20 [ (18.81±2.86) % vs. (22.03±1.91) %, t=-5.36, P<0.001] and D mean [ (11.66±1.32) Gy vs. (12.85±1.46) Gy, t=-4.10, P=0.007] of left lung, V 5 [ (5.70±2.90) % vs. (0.30±0.13) %, t=16.44, P<0.001] and D mean [ (2.45±0.29) Gy vs. (0.43±0.14) Gy, t=9.09, P<0.001] of right lung, D mean [ (3.22±0.72) Gy vs. (1.69±0.80) Gy, t=5.41, P<0.001] of right breast, D 2% [ (5.37±1.97) Gy vs. (0.46±0.09) Gy, t=11.75, P<0.001] of cord between VMAT and TD plans. There were no significant differences in the V 5 of left lung [ (53.00±5.99) % vs. (50.00±7.69) %, t=1.91, P=0.061], V 5 of right breast [ (11.51±4.60) % vs. (8.06±3.49) %, t=1.59, P=0.120], V 30 [ (1.49±0.69) % vs. (1.51±0.71) %, t=-0.06, P=0.952] and D mean [ (3.99±0.97) Gy vs. (3.90±1.03) Gy, t=0.56, P=0.581] of heart between the two plans. Conclusion:TD and VMAT can meet the clinical dosimetry requirements for patients with left breast cancer after breast-conserving surgery. However, the two techniques have their own characteristics. VMAT has better conformity and TD has better uniformity. TD is significantly better than VMAT in protecting the right lung, right breast and spinal cord of healthy organs at risk. VMAT is better in protecting the left lung. Both VMAT and TD basically achieve the same protection for heart.

Objective:To investigate the effect of V-Y advancement flap in the treatment of foot spoke injury in children.Methods:Clinical data of 8 patients, including 6 males and 2 females aged 2.5-5.0 (mean, 3.5) years old with foot spoke injury admitted to the Third Ward of Department of Orthopaedic Surgery, Xingtai General Hospital of North China Medical and Health Group from June 2019 to October 2021, were analysed retrospectively. Soft tissue defect around achilles tendon was 2.0 cm×3.0 cm-2.5 cm×4.0 cm. The size of the flap was 2.5 cm×3.5 cm-3.0 cm×4.5 cm. All patients underwent emergency debridement followed by V-Y advancement flap repair, and direct suture of the skin and tissues at donor site. The blood supply, survival and healing of flap of donor site were observed after operation. The shape of the heel and the functional recovery of the affected limb were examined on regular basis at the outpatient clinic.Results:All 8 flaps survived and the wounds had primary healing. The patients entered the follow-up for 6-12 months, with an average of 8 months. The texture and colour of the flap recipient site were good. The shape of the flap pedicle, the donor site and recipient site were satisfactory. The shoes wearing of the affected foot were not affected after surgery. The ankle function was good. The average extension was 25.8°(20°-30°), plantar flexion 32.5°(25°-40°), and the foot sensation and motion were close to normal. The average foot function score on American Association on Foot and Ankle Surgery(AOFAS) was 91.7±6.4. Five cases were excellent and 3 were good.Conclusion:The V-Y advancement flap demonstrates an ideal alternative method for treatment of small area of soft tissue defect around Achilles tendon, due to the simple operation, satisfactory shape of flap after repair, and favorable limb function.

Objective:To explore the application effects of standardized patient (SP) and breast visual palpation simulation system on clinical probation of breast surgery for medical students.Methods:A total of 110 students were randomly divided into experimental group and control group, and each group was further divided into 5 subgroups. In the experimental group, SP scripts of five common diseases in breast surgery department were designed according to the syllabus before probation, and the teachers were trained. During the probation, we first talked about the characteristics of disease diagnosis and treatment, and then the five subgroups collected the history of the disease according to the SP of different diseases mentioned above, and checked the corresponding lesions on the breast visual palpation simulation system. In the physical examination, SP responded to the students' questions. The control group also talked about the above-mentioned five diseases during the probation, and then the five subgroups carried out history collection and physical examination for specific patients in the hospital. Finally, the teaching effects were analyzed through medical record writing, theoretical examination, physical examination and student evaluation. SPSS 26.0 was used for chi-square test (or Fisher exact test) and Mann-Whitney U test. Results:There was no significant difference in the theoretical examination between the two groups. It was demonstrated that the correct rate of experimental group was significantly higher than that of the control group in medical history collection, especially in the main symptoms, incentives, aggravation and remission factors, accompanying and differential symptoms and so on. And the positive results of breast, nipple and axillary lymph node palpation in the experimental group were significantly higher than those in the control group through the physical examination operation of breast visual palpation simulation system. The analysis of students' evaluation showed that the teaching efficiency of the experimental group increased, and the students' satisfaction was improved (satisfaction rate: 92.73% vs. 76.36%).Conclusion:The application of SP and breast visual palpation simulation system in breast surgery probation teaching can not only protect the privacy of clinical patients, but also improve the teaching effects, which can be popularized in the clinical teaching of breast surgery.

Objective:To evaluate the relationship between the mechanism of promoting wound healing by modified autologous blood transfusion and metastasis-associated lung adenocarcinoma transcript 1 ( MALAT1) in diabetic mice. Methods:Twenty SPF ICR mice, weighing 21-25 g, in which the diabetic model was successfully established, were divided into 2 groups ( n=10 each) using a random number table method: modified preservation group (group I) and ordinary preservation group (group O). Peripheral venous blood samples were collected and stored in the corresponding preservation solution for 7 days.The platelet aggregation rate, blood glucose, serum glycosylated hemoglobin (GHB) and phosphodiesterase (DPG) concentrations and WBC were measured.Autologous blood was transfused back immediately after the wound model was established.The percentage of wound healing area was calculated at 7, 10 and 14 days after autologous blood transfusion.The expression of hypoxia-inducible factor-1α, vascular endothelial growth factor, matrix metalloproteinase-9, β-actin, type Ⅰ collagen (Col Ⅰ), Col Ⅲ protein and mRNA and MALAT1 was determined by Western blot, immunohistochemistry and quantitative real-time polymerase chain reaction respectively, at 14 days after transfusion. Results:Compared with group O, the blood glucose, serum concentrations of GHB and DPG, and WBC were significantly decreased, platelet aggregation rate was increased, the percentage of wound healing area was increased, the positive staining rate of Col Ⅰ and Col Ⅲ was increased, and the expression of hypoxia-inducible factor-1α, vascular endothelial growth factor, matrix metalloproteinase-9, ColⅠ, Col Ⅲ and β-actin protein and mRNA and MALAT1 was up-regulated in group I ( P<0.05). Conclusion:The mechanism by which modified autologous blood transfusion promotes wound healing may be related to up-regulating MALAT1 expression in diabetic mice.

Objective:To explore the effects of different approaches for second-trimester multifetal pregnancy reduction on pregnancy outcome in women with dichorionic triamniotic (DCTA) triplet.Methods:A retrospective study was performed on 51 women with DCTA triplet pregnancies who were referred to Guangdong Women and Children Hospital for second-trimester multifetal pregnancy reduction from January 2014 to January 2020. All participants were divided into either preventive group ( n=39) or treatment group ( n=12) according to the indication for multifetal pregnancy reduction, and they were further allocated to three subgroups based on different reduction methods, which were reduction to dichorionic twin by radiofrequency ablation (RFA) (RFA subgroup), reduction to monochorionic singleton (KCl-singleton subgroup) or monochorionic twin (KCl-twin subgroup) by cardiac injection of potassium chloride. Pregnancy loss rate, neonatal birth weight, gestational age at delivery, incidence of intrauterine death, and neonatal death were compared and analyzed between different groups using t-test, analysis of variance, Chi-square test, Fisher's exact test and Bonferroni correction. Results:(1) The mean gestational week at operation in the treatment group was significantly later than that in the preventive group [(18.5±3.1) vs (15.0±2.3) weeks, t=-4.209, P<0.001]. In the preventive group, the mean gestational week at operation in the RFA subgroup was later than the KCl-singleton and KCl-twin subgroup[(17.2±1.6) vs (13.8±1.5) and (12.7±1.0) weeks, t=6.630 and 3.875, respectively, both P<0.05]. (2) The postoperative pregnancy loss rate in the preventive group was decreased compared with the treatment group [10.3%(4/39) vs 5/12, Fisher's exact test, P<0.05], and the live birth ratio was increased [ 85.7%(48/56) vs 10/18, χ2=5.640, P=0.018]. No live birth infants with birth weight <1 500 g was reported in the KCl-singleton subgroup in preventive group, and the statistical significance was observed in the intra-group differences ( P<0.05) rather than the pairwise comparison differences in the preventive group. For the proportion of live births, there was a statistically significant difference in the intra-group comparison in the treatment group, which was higher in the RFA subgroup than that in the KCl-twin subgroup (6/6 vs 1/6, P=0.045). No significant difference was revealed among pregnancy loss rate, gestational weeks at delivery, the mean birth weight, premature delivery <32 gestational weeks, and full-term birth rate among three different approaches within the two groups. (3) No monochorionic twin complications or perinatal death occurred in any RFA or KCl-singleton subgroups in the two groups. In the KCl-twin subgroups including five cases with ten fetuses, including three live birth, four miscarriage, three intrauterine death occured, while no neonatal death was reported. One case with selective fetal uterine growth restriction in the preventive group delivered two live births, and one case with twin-to-twin transfusion syndrome in the treatment group had intrauterine death in one fetus and one survival neonate. Conclusions:The pregnancy outcome of multifetal pregnancy reduction to dichorionic diamniotic twins by RFA or reduction to singleton by cardiac injection of potassium chloride are comparative in women with DCTA triplet, regardless of whether it is a preventive or therapeutic reduction.

We report the intrauterine treatment of a case of fetal persistent supraventricular tachycardia complicated by heart failure. The ultrasound findings at 32 +1 weeks of gestation showed fetal tachycardia of 242 beats/min, fetal generalized edema, ascites, and visible pulsation spectrum in the intra-abdominal segment of the umbilical vein. Fetal cardiac arrhythmia persisted after maternal oral digoxin for 46 hours. In view of the continuous deterioration of the fetal condition with the persistent umbilical vein pulsation spectrum and worsening edema, fetal intramuscular injection of cedilanid under ultrasound guidance was performed, resulting in successful cardioversion. The pregnant woman gave birth to a baby girl by cesarean section due to premature rupture of membranes and oligohydramnios at 34 +6 weeks of gestation, with normal functions of heart and other organs. During a follow-up to 8 months, no obvious abnormalities were found.

Objective:To explore the effect of sports training guidance based on Internet platform on the limb function and quality of life in home rehabilitation of stroke hemiplegic patients.Methods:Eighty patients with stroke and hemiplegia admitted to Beijing Rehabilitation Hospital Affiliated to Capital Medical University from June 2018 to December 2019 were selected and divided into observation group and control group with 40 cases in each group by random digits table method. The control group was given routine rehabilitation training. In addition to the regular rehabilitation training, the observation group was supplemented with home rehabilitation based on the WeChat platform for modified constraint-induced movement therapy. The limb motor function Fugl-Meyer Assessment (FMA) score, Upper Extremity Function Test (UEFT) score, Stroke-Specific Quality of Life scale (SS-QOL) score before and after intervention, and patients′ satisfaction and cares′ satisfaction score were compared between the two groups.Results:There was no significant difference in the score of FMA, UEFT, SS-QOL before intervention between the two groups( P>0.05). After discharge, the FMA score, UEFT score and physical function, physiological function, mental health, social function of SS-QOL score were (68.87±6.64),(72.38±7.33), (35.28±4.13), (36.55±4.23), (37.22±3.84), (38.23±3.44) points in the observation group and (55.25±6.20), (61.24±6.47), (28.72±4.56), (30.85±5.30), (31.28±4.63), (31.02±5.16) points in the control group, and the differences were statistically significant between the two groups( t values were 5.316-9.482, P<0.01). During the nursing period, the patients′ satisfaction and cares′ satisfaction score were 92.50%(37/40), 87.50%(35/40) in the observation group and 72.50%(29/40), 67.50%(27/40) in the control group, and the differences were statistically significant between the two groups( χ 2 values were 5.541, 4.588, P<0.05). Conclusions:The home rehabilitation based on the Internet platform for modified constraint-induced movement therapy helps to promote the recovery of limb motor function in stroke hemiplegic patients, improve the nursing satisfaction of patients and their families, and has a positive effect on improving the quality of life of patients.

Objective:To explore the effect of situational simulation interactive training on rehabilitation compliance and motor function of stroke patients with hemiplegia.Methods:A total of 140 hemiplegic patients with stroke from July 2017 to October 2019 in Beijing Rehabilitation Hospital Affiliated to Capital Medical University were selected and divided into control group and observation group, 70 cases in each group. Routine treatment and rehabilitation nursing were used in the control group, and situational simulation interactive training were used in the observation group on the basis of the control group. Both groups were followed up for 6 months. Fugl-Meyer Assessment (FMA), World Health Organization Quality of Life Scale Brief (WHOQOL-BREF), Fugl-Meyer Assessment (FMA), self-made rehabilitation training compliance questionnaire and self-made nursing satisfaction questionnaire were used to evaluate the quality of life, motor ability, cognitive ability before intervention and after follow-up, rehabilitation compliance and nursing satisfaction after follow-up of the two groups.Results:There was no significant difference in FMA, WHOQOL-BREF and MMSE scores between the two groups before intervention ( P>0.05). After follow-up, the scores of FMA, WHOQOL-BREF and MMSE in the observation group were 62.57±6.52, 80.65±9.25, 25.30±3.24, significantly higher than 52.68±7.23, 66.68±8.34, 20.36±3.12 in the control group, the difference was statistically significant ( t value was 8.499, 9.385,9.189, P<0.05). After follow-up, the total compliance rate and satisfaction rate of the observation group were 92.86% (65/70) and 94.29% (66/70), respectively, while those of the control group were 78.57% (55/70) and 80.00% (56/70), respectively, the difference between the two groups was statistically significant (Fisher's exact test, P<0.05). Conclusions:The situation simulation rehabilitation training can effectively improve the motor function, rehabilitation compliance and nursing satisfaction of stroke patients with hemiplegia.

AIM: To observe the effect of acute normovolemic hemodilution (ANH) autologous blood transfusion on the EEG bispectral index and muscle relaxation in elderly patients undergoing orthopedic surgery to explore the influence of autologous blood transfusion containing anesthetic components on the quality and safety of postoperative anesthesia recovery. METHODS: Forty patients, aged 65-75, weighing 55-80 kg, ASA grade I-II, with an estimated intraoperative blood loss of more than 600 mL, were selected for elective orthopedic surgery. The patients were randomly divided into two groups (n=20): group A was given acute normovolemic hemodilution (ANH), and the target value of Hct was 28%-30% after induction of anesthesia; group B was the control group which was given routine fluid infusion during operation without ANH. Bispectral index (BIS), TOF values and plasma concentrations of propofol and cisatracurium were measured at the beginning of autotransfusion (T
