  • Effectiveness and Safety of Rabbit Antithymocyte Globulins for the Prevention of Graft-versus-host Disease: A Meta-analysis

    Objective Through conducting a meta-analysis using the methodology of Cochrane review, to assess the effectiveness and safety of graft-versus-host disease (GVHD) prophylaxis with antithymocyte globulins (ATGs) in allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods Such databases as PubMed (1966 to March 2011), EMbase (1974 to March 2011), the Science Citation Index databases (1900 to March 2011), The Cochrane Library (1996 to March 2011), CBMdisc (1978 to March 2011), and CNKI (1979 to March 2011) were electronical1y searched. The references of all identified studies were retrieved for collecting more randomized controlled trials (RCTs) and non-RCTs. Two reviewers independently screened the trials according to inclusion and exclusion criteria, abstracted the data, and assessed the methodology quality of the included studies. Meta-analyses were performed using RevMan 5.0.2 software. Results Thirteen clinical trials were included, of which 2 were RCTs involving 310 patients and the other 11 were non-RCTs involving 1480 patients. The results of meta-analyses showed that compared with the Non-ATG group, the pooled risk ratio (RR) and 95%CI of the ATG group in acute GVHD II-IV incidence rate, acute GVHD III-IV incidence rate, chronic GVHD (limited plus extensive) incidence rate, chronic GVHD (extensive) incidence rate, overall survival (OS) rate, non-relapse mortality (NRM) rate, and relapse rate were 0.77 (0.67, 0.87), 0.54 (0.44, 0.68), 0.58 (0.51, 0.65), 0.35 (0.26, 0.46), 1.14 (1.04, 1.25), 0.81 (0.69, 0.93), and 1.24 (0.98, 1.57), respectively. Conclusion The addition of ATGs to GVHD prophylaxis can reduce the incidence of acute and chronic GVHD, decrease NRM, and increase OS, but has no obvious interference with relapse rate.

  • Giant Cell Interstitial Pneumonia: Two Cases Report and Literature Reviews

    Objective To highlight the characteristics of giant cell interstitial pneumonia ( GIP) . Methods The clinical, radiological, and pathological data of two patients with GIP pathologically proven by open lung and TBLB biopsy were presented respectively, and relevant literatures were reviewed. Results Patients with GIP usually had a history of exposure to metal dust. Clinical presentations included cough and dyspnea on exertion, and pulmonary function testing showed a restrictive abnormality. On chest radiography and high-resolution CT scans, it presented as bilateral areas of ground-glass attenuation, areas of consolidation, diffuse small nodules, extensive reticular opacities, and traction bronchiectasis. The main pathological findings included a desquamative interstitial pneumonia ( DIP) -like reaction with intra alveolar macrophages and numerous large multinucleated histiocytes that ingested inflammatory cells were admixed with macrophages. The finding of GIP was almost pathognomonic for hard metal pneumoconiosis. Conclusions GIP is a very rare chronic interstitial pneumonia, and has no characteristic clinical manifestations. Radiographic findings are similar to other idiopathic interstitial pneumonias. Careful collection of the occupational history can help to minimize misdiagnosis.

  • Assessment of laparoscopic training based on eye tracker and electroencephalograph

    The aim of this study is to evaluate the effect of laparoscopic simulation training with different attention. Attention was appraised using the sample entropy and θ/β value, which were calculated according to electroencephalograph (EEG) signal collected with BrainLink. The effect of laparoscopic simulation training was evaluated using the completion time, error number and fixation number, which were calculated according to eye movement signal collected with Tobii eye tracker. Twenty volunteers were recruited in this study. Those with the sample entropy lower than 0.77 were classified into group A and those higher than 0.77 into group B. The results showed that the sample entropy of group A was lower than that of group B, and fluctuations of A were more steady. However, the sample entropy of group B showed steady fluctuations in the first five trainings, and then demonstrated relatively dramatic fluctuates in the later five trainings. Compared with that of group B, the θ/β value of group A was smaller and shows steady fluctuations. Group A has a shorter completion time, less errors and faster decrease of fixation number. Therefore, this study reached the following conclusion that the attention of the trainees would affect the training effect. Members in group A, who had a higher attention were more efficient and faster training. For those in group B, although their training skills have been improved, they needed a longer time to reach a plateau.

  • Surgical treatment for hypertrophic obstructive cardiomyopathy associated with aortic stenosis

    Objective To evaluate the clinical and follow-up results of the surgical treatment for hypertrophic obstructive cardiomyopathy associated with aortic stenosis. Methods We retrospectively analyzed the clinical data of the patients with hypertrophic obstructive cardiomyopathy plus aortic stenosis in our hospital from February 2008 to October 2015. There were 4 males and 3 females aged 55.6 ± 7.5 years. All the patients were received concomitant aortic valvulopasty at the time of modified extended Morrow procedure. Echocardiographic data and major complications were recorded through the outpatient clinic and telephone. Results The postoperative ventricular septal thickness, left ventricular outflow tract gradient and aortic gradient were significantly lower than those in preoperation with statistical differences (P<0.05). During the mean follow-up 25.6 ± 28.2 months period, 1 patient died of cerebral hemorrhage, 1 patient was implanted a permanent pacemaker, and 1 patient had a postoperative new-onset atrial fibrillation. All patients had a satisfied prosthetic valve function and the left ventricular outflow tract gradient. The patient's symptoms and heart function significantly improved postoperatively. Conclusion For patients with hypertrophic obstructive cardiomyopathy associated with moderate to severe aortic stenosis, concomitant aortic valvulopasty at the time of modified extended Morrow procedure is an appropriate and effective treatment, which can significantly alleviate the clinical symptoms, and improve quality of life with a satisfied prognosis.

  • Research and application of the training method for hospital infection management teachers through the whole process of diagnosis and treatment

    Objective To study the effect of training methods for hospital infection management that through the whole process of diagnosis and treatment. Methods We selected part-time hospital infection personnel from Panyu Central Hospital of Guangzhou to form a teaching staff between January 1 and October 31, 2022. The teaching staff was randomly divided into a control group and an experimental group using a random number table method. The control group received training using traditional theoretical training models, while the experimental group received training using a simulated hospital infection training teaching model that runs through the entire diagnosis and treatment process. The training effects of the two groups through theoretical knowledge assessment, operational skills assessment, and teacher satisfaction evaluation were compared. Results A total of 196 teachers were included, with 98 students in each group. There was no statistically significant difference between the two groups in terms of gender, age, education level, major category, professional title, and years of work experience (P>0.05). The total score of theoretical knowledge examination in the experimental group [(88.49±8.33) vs. (80.35±13.57) points, t=5.062, P<0.001] was higher than the control group. Among them, the scores of hand hygiene standards for medical personnel, principles of aseptic operation, occupational exposure disposal, classification and disposal of medical waste were significantly higher than those of the control group (P<0.05). The total score of the operational skills assessment in the experimental group was higher than that in the control group [(86.37±5.25) vs. (76.75±7.07) points, t=10.811, P<0.001], among which the scores during operation, after operation, and overall impression were significantly higher than the control group (P<0.05). The overall satisfaction in the experimental group was higher than that of the control group (94.90% vs. 72.45%, χ2=18.076, P<0.001), among which the satisfaction with training methods, textbook value, course attractiveness, and clinical applicability were higher than those of the control group (P<0.05). Conclusions Through the whole process of diagnosis and treatment training method for hospital infection management can significantly improve the training effectiveness of teachers. It is worth promoting in the teaching of hospital infection management for various levels and types of personnel.

  • Discussion on the influencing factors of beating heart coronary artery bypass grafting

    Objective To explore the factors affecting the operation of coronary artery bypass grafting with heart beating and improve the effect of the operation. MethodsFrom January 2012 to June 2016, 898 patients with coronary heart disease who received cardiovascular surgery in the Second Affiliated Hospital of Jilin University were analyzed retrospectively. All patients only underwent coronary artery bypass grafting with beating heart. Among them, 797 patients underwent the off-pump coronary artery bypass grafting (an OPCABG group, 592 males and 205 females, with an average age of 60.5±8.4 years); another 101 patients received on-pump beating heart coronary artery bypass grafting (an OPBH group, 77 males and 24 females, with an average age of 61.5±8.2 years). ResultsThe average number of grafts in the OPCABG group was 3.36±0.74, and in the OPBH group was 3.71±0.69 (P<0.05). The postoperative ventilation time (10.8±9.5 h vs. 20.6±12.3 h), ICU stay (28.8±15.5 h vs. 37.4±30.8 h), hospital stay (10.9±4.8 d vs. 14.8±8.6 d), mortality (1.1% vs. 3.0%), the utilization rate of intra-aortic balloon pump (2.4% vs. 8.9%) and extracorporeal membrane oxygenation (0.5% vs. 5.0%) were significantly different between the OPCABG group and OPBH group (all P<0.05). Twelve patients died after surgery, and the total bloodless operation ratio was 91.3%. ConclusionThe results show that most patients can achieve good results with the help of apical fixation and myocardial fixator, improved surgical techniques and methods, good anesthesia management as well as flexible and accurate use of vasoactive drugs. But extracorporeal circulation is necessary in the patients with large left ventricle, low ejection fraction and hemodynamic instability after intraoperatively moving the heart.
