ABSTRACT

Objective:To analyze the costs and effectiveness of five common screening modes and genetic screening for thalassemia in China in order to find the optimal way and provide evidence for the implementation of thalassemia prevention and control projects in Hunan Province.Methods:From June 2020 to April 2021, 12 971 couples from 14 cities and autonomous prefectures in Hunan Province were selected as the study population. The diagnosis of thalassemia was based on the results of genetic testing. Results of routine blood test and hemoglobin electrophoresis were collected and analyzed. The efficacy of five screening modes, at the cut-off value of <80 fl or 82 fl for the mean corpuscular volume (MCV), was analyzed by positive predictive value, negative predictive value, Jorden index and cost-effectiveness ratio. Sensitivity analysis was used to assess the feasibility of genetic screening at different costs after fixing the costs of routine blood and hemoglobin electrophoresis. The five thalassemia screening models are as follows: Mode 1: The woman had a blood routine test first. If the result was positive, the spouse required a blood routine test. If both results were positive, a thalassemia gene test should be offered to the couple. Mode 2: Both husband and wife were screened by blood routine and hemoglobin electrophoresis. If one or both of them were positive, both would be tested for thalassemia gene. Mode 3: The couple received blood routine tests initially. If either was positive, both should receive hemoglobin electrophoresis testing. If either was positive, both parties will conduct thalassemia gene testing. Mode 4: The woman was screened by blood routine and hemoglobin electrophoresis. If any one of them was positive, the woman would be tested for thalassemia gene. If the gene test result was positive, the spouse should receive thalassemia gene. Mode 5: Both spouses conducted a blood routine test. If either was positive, both would conduct hemoglobin electrophoresis test. If both were positive, both spouses should receive thalassemia gene testing. Gene testing mode: The woman would be tested for thalassemia, and her spouse would have thalassemia test too if her result was positive.Results:When using MCV<80 fl as the cut-off for diagnosing thalassemia, the Youden indices of the five prenatal screening modes in Hunan Province were 0.551, 0.639, 0.898, 0.555 and 0.356, while when using MCV<82 fl as the cut-off, the Youden indices were 0.549, 0.629, 0.851, 0.548 and 0.356. When the MCV cut-off value was <80 fl, the missed diagnosis rates of the five screening modes were 44.44%, 0.00, 0.00, 18.52% and 62.96%, and the cost-effectiveness ratios were 21 709, 250 939, 76 870, 138 463 and 92 860 yuan (RMB)/couple, respectively. When the price of genetic testing was lower than 55 yuan (RMB), the cost-effectiveness ratio of genetic screening was lower than that of Mode 3.Conclusions:MCV<80 fl can be considered as the positive criteria in blood routine screening for thalassemia in Hunan Province, and the cost-effectiveness ratio of Mode 3 (the couple received blood routine tests initially. If either was positive, both should receive hemoglobin electrophoresis testing. If either was positive, both parties will conduct thalassemia gene testing) is the best. Genetic screening has certain advantages with the decreasing price.

ABSTRACT

Objective:To evaluate the safety of leadless pacemaker implantation in super-elderly patients.Methods:Eleven patients with average age of 90 (86, 92) years who underwent leadless pacemaker implantation in the Department of Cardiology, Peking University People′s Hospital from March 2021 to May 2022 were included. The clinical data and implantation information were collected. The complications (cardiac tamponade, myocardial infarction, cerebral infarction, pulmonary embolism, pacemaker reinfection, femoral vein hematoma) and death of patients were documented at 24 h, 3 d, and 1, 3, 6 months after pacemaker implantation.Results:There were 9 males and 2 females with the body mass index of 21(19, 23)kg/m 2. The underlying diseases were hypertension, diabetes, coronary heart disease, chronic kidney disease, chronic obstructive pulmonary disease, previous cerebral infarction and moderate to severe tricuspid regurgitation in 9, 9, 9, 6, 4, 4, 4 patients, respectively. The left ventricular ejection fraction was 49% (45%, 52%), the hemoglobin concentration was 118 (114, 122)g/L, 4 patients were taking anticoagulant drugs, and 6 patients were taking antiplatelet drugs. Eight patients were newly implanted with a leadless pacemaker, 2 patients were implanted after removal the old ones, and 1 case was implanted at the same time as removal. The implantation time was 45(40, 47) minutes, the X-ray exposure time was 14 (13, 15) minutes, the release time was 1 (1, 2), the threshold value was 0.50(0.38, 0.75)V/0.24 ms, the impedance was 730 (700, 770) Ω, and the perceived R-wave amplitude 8.2(6.7, 12.8) mV. During the follow-up period of 8 (6, 10) months, no patient had pacemaker dysfunction; and the threshold, R wave sensing, and impedance were stable and maintained within the normal range. No cardiac tamponade, myocardial infarction, cerebral infarction, pulmonary embolism, pacemaker reinfection or death occurred perioperatively and during the follow-up period; 1 patient had hematoma after femoral vein puncture, which improved after compression treatment. Conclusion:This single-center and small-sample study shows that leadless pacemaker implantation is safe for super-elderly patients.

ABSTRACT

OBJECTIVE@#To explore lumbar plexus nerve block combined with general anesthesia in elderly patients undergoing hip operation could improve analgesia effect, reduce consumption of analgesics, prevent inflammatory reaction, and avoid postoperative delirium(POD).@*METHODS@#Totally 200 elderly patients underwent hip fracture surgery from February 2020 to September 2021 were selected and were divided into observation group and control group according to different anesthesia methods. There were 97 patients in observation group including 66 males and 33 females; aged (70.23±6.60) years old;body mass index (BMI) was (23.13±1.94) kg·m-2;19 patients with hemi arthroplasty, 46 patients with total hip arthroplasty, and 32 patients with femur intertrochanteric fixation;treated with lumbar plexus block combined with general anesthesia. There were 94 patients in control group, including 66 males and 33 females;aged (68.80±6.24) years old;BMI was (22.88±1.85) kg·m-2;14 patients with hemi arthroplasty, 39 patients with total hip arthroplasty, and 41 patients with femur intertrochanteric fixation;treated with only general anesthesia. Nine patients were separated due to the change of surgical protocol or chronic disease. The incidence of POD at 1, 2 and 3 days after surgery, mini-mental state examination (MMSE) score, visual analogue scale (VAS) in resting state, serum inflammatory factors levels [such as C-reactive protein(CRP), interleukin-1β(IL-1β), interleukin-6(IL-6), tumor necrosis factor-α(TNF-α)] at 1 d before operation, 1 and 6 h after surgery, consumption of sufentanil between two groups were compared.@*RESULTS@#The incidences of POD in observation group were lower than control group at 1, 2 and 3 days of operation (P<0.05), MMSE score in observation group was higher than that of control group (P<0.05), VAS in observation group was lower than that of control group (P<0.01). The incidences of POD decreased and MMSE score were increaed in both groups day by day (P<0.01). The levels of CRP, IL-1β, IL-6 and TNF-α in observation group were lower than that of control group at 1 h after operation (P<0.01). The levels of CRP, IL-6 and TNF-α in observation group were lower than that of control group at 6 h after operation (P<0.01), while no statisitical difference in IL-1β between two groups(P>0.05). The consumption of sufentanil in observation group was lower than that of control group (P<0.01).@*CONCLUSION@#Compared with general anesthesia, lumbar plexus nerve block combined with general anesthesia for the operations of hip fracture in elderly patients has better analgesic effect, has advantages of slight inflammatory reaction, and could decrease consumption of opioid and incidence of POD.

ABSTRACT

Developmental changes in children can affect drug disposition and clinical effects. A physiologically-based pharmacokinetic (PBPK) model is a mathematical model that can be used to predict blood drug concentrations in children and gain insight into age-dependent physiological differences in drug disposition impact. Pediatric PBPK (P-PBPK) models have attracted attention over the past decade. With the concerted efforts of academia, pharmaceutical companies, and regulatory agencies, there are more and more examples of pediatric clinical studies using PBPK models. Nevertheless, the number of P-PBPK models and their predictive performance still lag behind adult models. By referring to the literature, we study the process of children adapting to adult absorption, distribution, metabolism, and excretion (ADME) parameters and analyze the general principles of P-PBPK model establishment. In addition, we summarize the functions and application examples of commonly used P-PBPK modeling software to provide a basis for the rational application of modeling software.

ABSTRACT

OBJECTIVE@#This study was aimed at investigating the carrier rate of, and molecular variation in, α- and β-globin gene mutations in Hunan Province.@*METHODS@#We recruited 25,946 individuals attending premarital screening from 42 districts and counties in all 14 cities of Hunan Province. Hematological screening was performed, and molecular parameters were assessed.@*RESULTS@#The overall carrier rate of thalassemia was 7.1%, including 4.83% for α-thalassemia, 2.15% for β-thalassemia, and 0.12% for both α- and β-thalassemia. The highest carrier rate of thalassemia was in Yongzhou (14.57%). The most abundant genotype of α-thalassemia and β-thalassemia was -α 3.7/αα (50.23%) and β IVS-II-654/β N (28.23%), respectively. Four α-globin mutations [CD108 (ACC>AAC), CAP +29 (G>C), Hb Agrinio and Hb Cervantes] and six β-globin mutations [CAP +8 (C>T), IVS-II-848 (C>T), -56 (G>C), beta nt-77 (G>C), codon 20/21 (-TGGA) and Hb Knossos] had not previously been identified in China. Furthermore, this study provides the first report of the carrier rates of abnormal hemoglobin variants and α-globin triplication in Hunan Province, which were 0.49% and 1.99%, respectively.@*CONCLUSION@#Our study demonstrates the high complexity and diversity of thalassemia gene mutations in the Hunan population. The results should facilitate genetic counselling and the prevention of severe thalassemia in this region.

ABSTRACT

In order to provide the basis for the development of famous classical formulas, the name, origin, quality evaluation, harvesting and processing of Eucommiae Cortex were systematically researched by consulting the ancient herbal and medical books, combining with the modern literature. According to the textual research, materia medica in the past dynasties used Eucommiae Cortex as the correct name. Combined with characteristics, origin and efficacy, Eucommiae Cortex in ancient times to the present is the dry bark of Eucommia ulmoides from family Eucommiaceae. The earliest producing areas of Eucommiae Cortex are Henan, Shanxi, Shaanxi and Sichuan. Since the Ming dynasty, the producing areas have expanded to most of the regions in the country, and Sichuan, Shaanxi, Chongqing, Guizhou and Hubei are regarded as the authentic producing areas. It has been concluded that the quality of Eucommiae Cortex is best if the bark has thick body, large block, scraped rough skin, multi silk section and dark purple internal surface. In ancient times, the processing methods of Eucommiae Cortex were mainly included removing rough bark and cutting for raw use, processing with auxiliary materials such as honey, ginger juice, salt water, wine, and so on. While in modern times, the processing methods have become increasingly simplified which are mainly cutting raw materials after cleansing and salt processing. It is need to excavate the connotation of different processed products and restore the traditional main processing methods through standards. Based on the requirement of Eucommiae Cortex in Sanbitang, it is suggested to use ginger-processed products according to the research results, which is used ginger juice as auxiliary material and processed with stir frying method according to the 2020 edition of Chinese Pharmacopoeia.

ABSTRACT

OBJECTIVE@#To evaluate the effects of acupuncture on hypoglycaemic outcomes in type 2 diabetes mellitus (T2DM).@*METHODS@#PubMed, Embase, Cochrane Library, and ClinicalTrials.gov were searched from inception up to July 2020, to identify randomised controlled trials (RCTs) that enrolled patients with T2DM and compared acupuncture combined with antidiabetic drugs to antidiabetic drugs alone. The primary outcomes were haemoglobin A1c (HbA1c) and fasting blood glucose (FBG). The secondary outcomes included 2-h blood glucose (2hBG), fasting insulin (FINS), homeostatic model assessment for insulin resistance (HOMA-IR), and acupuncture-related adverse events. Mean difference (MD) and 95% confidence interval (CI) were used as the effect measure in the meta-analysis. The quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation tool.@*RESULTS@#Twenty-one RCTs (n=1,188) were included. The meta-analytic results showed that the acupuncture group had greater reductions in FBG (MD -6.46 mg/dL, 95% CI -11.95 to -0.98; moderate-quality evidence) and HOMA-IR (MD -1.23, 95% CI -2.16 to -0.31; low-quality evidence), but comparable changes in HbA1c (MD -0.39%, 95% CI -0.84 to 1.61; very-low-quality evidence), 2hBG (MD -4.99 mg/dL, 95% CI -20.74 to 10.76; low-quality evidence), and FINS (MD -1.32 µIU/mL, 95% CI -3.76 to 1.12; low-quality evidence). No data on the incidence of diabetic complications were found. All acupuncture-related adverse events reported were mild.@*CONCLUSIONS@#The current evidence suggests that acupuncture, as a complementary therapy to antidiabetic drugs, has a small but statistically significant effect on decreasing FBG and improving insulin resistance. The effects of acupuncture on HbA1c, 2hBG, and FINS remain uncertain. Acupuncture is generally safe in patients with mild diabetes. More evidence for the long-term effects of acupuncture on T2DM is needed. (Trial registration No. CRD42018115639).

ABSTRACT

Objective To determine the radiation dose of sensitive organs under different protective methods in lung CT scanning environment, and to explore the best protective scheme of corresponding organs. Methods Annealed thermoluminescence dose elements were placed in the stomach, liver, colon, and thyroid gland of a simulated human body model. The dose effect experiment of protective methods included non-protective group, half lead apron group, and full lead apron group. The dose effect experiment of protective thickness included 0.50 mmpb full lead apron group and 0.35 mmpb full lead apron group. The same exposure conditions of lung CT scan were used in the above experiments. Results Compared with the non-protective group, the exposure dose of the stomach, liver, colon, and thyroid gland increased significantly in the half lead apron group (P < 0.05), and the exposure dose of the thyroid gland and colon decreased significantly in the full lead apron group (P < 0.05). There were no significant differences in the exposure dose of the liver, stomach, and colon in the simulated human body model between the 0.35 mmpb full lead apron group and the 0.50 mmpb full lead apron group. Conclusion For lung CT scan, the protective measure of lead apron may not reduce the exposure dose of subjects. The protective thickness of lead apron does not necessarily have a substantial influence on the exposure dose of human body.

ABSTRACT

Objective:To investigate the clinical experience of using orbital fat pedicle to correct eyebags with the tear trough and palpebromalar groove deformity.Methods:From February 2020 to May 2021, 35 patients with lower blepharoplasty combined with orbital fat-release were treated in the Facial and Neck Plastic Surgery Center of the Plastic Surgery Hospital of Chinese Academy of Medical Sciences, including 4 males and 31 females. Their age ranged from 35 to 63 years, with an average age of 47.5 years. Different degrees of lower eyelid skin laxity, orbital fat herniation, moderate and severe tear trough, palpebromalar groove deformity were observed in all patients. Preoperative examination showed no symptoms such as lower eyelid ectropion and lower eyelid retreat ment. All 35 patients were treated with transcutaneous incision blepharoplasty, in which the orbital septal fat was released, pulled downward and internally fixed to the appropriate position to fill the tear trough and palpebromalar groove.Results:All patients obtained primary healing, no complications such as hematoma, and infection occured. Postoperative follow-up lasted from 3 to 18 months, with an average of 8.6 months. 35 patients′ eye bags with tear trough and palpebromalar groove deformity were obviously alleviated. Unilateral mild eye bag remained in 2 patients in postoperative 1 month, and 2 cases appeared mild lower eyelid ectropion postoperatively, none of these patients received special treatment and recovered after 3 months.Conclusions:Lower blepharoplasty combined with orbital fat release can effectively repair eye bags and correct tear trough and palpebromalar groove deformity.

ABSTRACT

Objective:To explore the effect of maternal stress perception and plasma serotonin level in the first or second trimester on breastfeeding behavior, and to provide evidence for promoting exclusive breastfeeding.Methods:This prospective cohort study recruited pregnant women (≤20 gestational weeks) from Maternal and Child Health Center of Gulou District from April 2019 to March 2020. Stress perception at study enrollment was evaluated using Perceived Stress Scale (PSS) and the maternal plasma serotonin level was detected. Telephone interviews were conducted 42 d after delivery to collect information on childbirth and breastfeeding. Chi-square test, two independent samples t-test, and logistic regression model were used to analyze the risk factors of non-exclusive breastfeeding. Results:A total of 366 pregnant women were enrolled and 353 (96.4%) of them completed telephone interviews, who were divided into the exclusive ( n=194) and non-exclusive breastfeeding group ( n=159). Univariate analysis showed that the PSS scores [(19.4±6.9) vs (21.1±6.9) scores, t=-2.25, P=0.026] and the proportion of high-stress perception [23.7% (46/194) vs 34.0% (54/159), χ 2=4.03, P=0.045] in the exclusive group were all significantly lower than those in non-exclusive group. In the logistic regression analysis, exclusive breastfeeding was set as the dependent variable and the independent variables included factors with P<0.200 in the univariate analysis (PSS scores or PSS rating, plasma serotonin level, age, delivery mode) and potential clinical risk factors (parity, preterm birth). The results showed that when PSS was considered as a continuous variable, total PSS scores in the first or second trimester was an independent risk factor for non-exclusive breastfeeding ( OR=1.043, 95% CI: 1.010-1.077, P=0.011) and so was the high-stress perception when PSS was considered as a categorical variable (PSS rating) ( OR=1.765, 95% CI: 1.097-2.854, P=0.020). Conclusions:Overstress in the first or second trimester will affect breastfeeding patterns. Mental health counseling may help relieve perinatal stress, which will further increase the exclusive breastfeeding rate.

ABSTRACT

Objective@#To investigate the recurrence of pulmonary tuberculosis patients 5 years after successful treatment in Hengyang City, Hunan Province, and to analyze its influencing factors.@*Methods@#The data of pulmonary tuberculosis patients who were successfully treated in Hengyang City in 2014 were collected through the tuberculosis management information system. The recurrence of pulmonary tuberculosis was defined as the endpoint, and all patients were observed for five consecutive years. Factors affecting recurrence of pulmonary tuberculosis were identified using Kaplan-Meier estimates, log-rank test and multivariable Cox proportional hazards regression analysis.@*Results@#A total of 6 626 patients with successfully treated pulmonary tuberculosis were included, including 4 961 males and 1 665 females, with a median age of 54 years. There were 536 cases with recurrence of pulmonary tuberculosis within five years, with a 8.09% cumulative proportion of recurrence and annual recurrence rate of 1.75 per 100 person-years. Multivariable Cox proportional hazards regression analysis showed that men ( HR=1.592, 95%CI: 1.256-2.019 ), age of 40 years and greater ( age of 40 to 59 years, HR=7.025, 95%CI: 1.739-28.377; age of 60 years and greater, HR=8.175, 95%CI: 2.024-33.023), farmers ( HR=1.379, 95%CI: 1.070-1.778 ), retreatment ( HR=6.398, 95%CI: 5.163-7.929 ) and positive etiology ( HR=1.255, 95%CI: 1.042-1.511 ) were risk factors for five-year recurrence of pulmonary tuberculosis among successfully-treated patients.@*Conclusions@#High recurrence rate is found among pulmonary tuberculosis patients within five years after successful treatment in Hengyang City. There is a high risk of pulmonary tuberculosis recurrence among male, etiologically positive, retreated farmers at ages of 40 years and older, and targeted interventions are recommended.

ABSTRACT

Heat-sensitive moxibustion is the appropriate technique of the external treatment in traditional Chinese medicine and it is widely used in community because of its "easy learning, simple operation and clear curative effect". Pragmatic randomized controlled trial is a main intervention design in the real world study, which provides a high-level evidence for the effectiveness assessment of heat-sensitive moxibustion in community management. Focusing on the key links of randomization, e.g. block randomization, stratified randomization, cluster randomization, sample size allocation, allocation concealment and blinding, the paper elaborates the advantages, disadvantages and technical details of two-stage randomization with consideration of patient preference in pragmatic randomized controlled trials of heat-sensitive moxibustion in community. It facilitates improving the quality of evidence, reproducibility and methodological homogeneity among different trials.

ABSTRACT

Objective: To explore the feasibility of reconstruction of nasal tip with septal cartilage and auricular cartilage. Methods: From September 2018 to October 2019, 17 patients (two males and fifteen females) with low noses underwent rhinoplasty under general anesthesia. The age of the patients ranged from 19 to 39, with an average of 27 years old. Among them, all the 17 cases were primary rhinoplasty. During the operation, autologous nasal septum cartilage was used as septal extension graft to extend the caudal septum, and the auricular cartilage was used to enhance the stability of the strut and to elevate the tip for adjusting the shape of nose by making into spreader graft, columellar strut graft, derotation graft and onlay graft. The nasal dorsum was filled with polytetrafluoroethylene. Digital scanning technology was used to evaluate the nasal structure before and after operation. SPSS 22 software was used to analyze the data with paired t-test. Results: The follow-up was from 6 to 12 months, with an avaerge of 7.6 months. Seventeen patients were satisfied with postoperative nasal morphology and height. There was no infection, prosthesis displacement, skin flap necrosis, no auricle deformation and other complications. Statistical software SPSS 22 performed paired t-test on the preoperative and postoperative data obtained by digital technology: postoperative nasal length and nasal tip protrusion increased compared with that before surgery, and it was statistically significant(length:(3.60±0.77)mm, tip protrusion:(3.61±0.64)mm, t value was -19.203 and -23.132 respectively, both P<0.001). The nasolabial Angle was smaller than that before surgery, and the data were statistically significant(3.40°±2.11°,t=6.635, P<0.001). Conclusion: The nasal tip and nasal septum extension complex constructed by autogenous nasal septal cartilage combined with auricular cartilage can increase the length of nasal tip, increase the height of nasal tip and reduce the angle of nasolabial angle.

ABSTRACT

Objective: To observe the clinical efficacy of pediatric massage (tuina) for chronic cough in children. Methods: A total of 96 cases were randomized into a control group and an observation group, with 48 cases in each group. Cases in the control group received routine pediatric massage manipulations. Cases in the observation group received additional Mo-rubbing abdomen manipulation. The treatment was done 3 times a week and 12 times made up a treatment session. The cough symptom scores were evaluated before treatment and after 3, 6, 9 and 12 treatments respectively. Results: There were 8 dropouts in the observation group and 5 dropouts in the control group. Before treatment, there was no statistical difference in coughing score between the two groups (P>0.05). After 9 times of treatment, the total coughing scores were significantly reduced in both groups (both P<0.05); however, there were no statistical differences between the two groups in the score differences between before treatment and after 3, 6 and 9 times of treatment (all P>0.05). After 12 times of treatment, the total coughing scores were significantly reduced in both groups (both P<0.05), along with a statistical difference between the two groups in the score difference between before treatment and after 12 times of treatment (P<0.05). There was a statistical difference between the two groups in overall response (P<0.05). The total effective rate in the observation group was 92.5%, versus 86.0% in the control group, showing a statistical difference (P<0.05). Conclusion: The routine pediatric massage manipulations alone or in combination with Mo-rubbing abdomen manipulation both can significantly improve chronic cough in children; however, the combination obtains a better effect.

ABSTRACT

Objective:To investigate the method and application experience of nasolabial subcutaneous pedicled flap in the repair of skin defect after resection of nasolabial mass.Methods:From December 2016 to December 2020, a total of 58 patients (43 cases of nevus, 12 cases of seborrheic keratosis and 3 cases of keratinacanthoma) were admitted to the Facial Neck Center of Plastic Surgery Hospital of Chinese Academy of Medical Sciences, including 24 males and 34 females. They ranged from 17 to 55 years old, with an average age of 33 years. The minimum facial tumor area was 0.8 cm×0.8 cmand the maximum was 2.2 cm×2.0 cm. A local skin flap with a subcutaneous pedicle was designed preoperatively in the nasolabial groove area, and the subcutaneous pedicle was transferred to the defect area through subcutaneous tunnel or by disconnecting the surrounding tissue. The tumor was removed and the skin defect was closed at one stage. Postoperative complications were summarized and patient's satisfaction was investigated.Results:Follow-up period ranged from 6 to 48 months. All the 58 patients had primary healing of the transfer incisions, and all the flaps survived. The blood supply of the flaps was good, and the scar of the operative area was smooth. After resection of peri-lip mass, there was 1 case with obvious scar in the donor area of nasolabial groove, and the overall satisfaction rate was 98.3%.Conclusions:The application of nasolabial subcutaneous pedicled skin flap to repair the skin defect after resection of nasolabial tumor has the advantages of preventing the pulling deformation of the organ, it can be completed in one stage and repair the facial skin defect from a distant position. In addition, the thickness and color of the skin flap are similar to the defect site, and the scar of the donor site is not obvious, and so the appearance and function of the surgery can be satisfied.

ABSTRACT

Objective:To develop an innovational hybrid simulation-based education of bone traction with co-Debriefer for medical students and to evaluate its effectiveness.Methods:This study was designed as a cross-controlled study. From June 2018 to June 2019, 28 medical students were randomized into two groups. The two groups adopted simulation-based education and traditional teaching method respectively. In the second week of internship, the teaching methods of the two groups exchanged. Scores rating of the skill were used to assess the students' performance in the end of each teaching methods. SPSS 23.0 software was used to analyze the collected data.Results:In the first weekend of orthopedic-internship, students in the experimental group scored significantly higher than the control group, with an average score of 85.07 points versus 67.92 points. In the second weekend of practice, there was no obvious change in the skill score of the experimental group, but the score of the control group was significantly improved, and there was no obvious difference with the experimental group.Conclusion:The hybrid simulation-based education with co-debriefing is a reliable teaching method for medical interns to learn skills of bone traction, which can effectively help improve students' skills, reduce their errors, and ensure patient's safety.
