Academic buoyancy refers to the ability of students to successfully overcome typical, non-major academic setbacks and challenges encountered in daily school life. It can affect students' academic behaviors, academic achievements, and emotional experiences. This paper reviews academic buoyancy from four perspectives: its definition, measurement tools, effects, and intervention strategies. Additionally, it analyzes the applicability of introducing academic buoyancy to nursing students in China, with the aim of providing a new perspective to alleviate academic pressure and improve academic behaviors among nursing students.

Purpose: This study aimed to evaluate the safety of biologics and small molecules for the treatment of inflammatory bowel diseases (IBD) in patients receiving antirejection therapies after organ transplants. Materials and Methods: We reviewed the medical records of patients with IBD who received organ transplants at the Asan Medical Center between January 1989 and December 2021. We compared the parameters of patients receiving biologics or small molecules to those of patients without those therapies. Results: This study included a total of 53 patients (ulcerative colitis, 41; Crohn’s disease, 6; and gastrointestinal Behçet’s disease, 6). Among them, 15 patients were receiving biologics or small molecules and 38 were not. During a mean follow-up of 119 months, the proportion of patients experiencing severe infections was significantly higher in those treated with biologics or small molecules than in those not treated. However, other safety outcomes (e.g., malignancies, adverse events, including organizing pneumonia or hepatic failure, and death) were not different between the two groups. Kaplan–Meier curve analysis revealed no significant difference in the safety outcome rate related to the use of biologics or small molecules. During follow-up, eight patients underwent bowel resections for IBD. The rate of bowel resection was not different between the two groups. Conclusion The use of biologics or small molecules for patients with IBD who received organ transplants did not show a significant difference in safety outcomes. However, the possibility of severe infections must be considered.

Objective:To revise the family resilience assessment scale (FRAS) in patients with stroke and to evaluate its psychometric properties and applicability.Methods:FRAS was authorized and translated into Chinese.The scale items were revised based on the interview results of 13 patients with stroke and 11 caregivers and the opinions of 20 experts in related fields.A convenience sampling method was used to sample neurology and neurosurgery inpatients from 2 tertiary hospitals in Hangzhou twice from June to November 2022, with 325 questionnaires (sample 1) distributed the first time for item analysis and exploratory factor analysis, and 285 questionnaires (sample 2) distributed the second time for confirmatory factor analysis, criterion validity and reliability test.Data analysis was conducted by SPSS 26.0 and AMOS 24.0.Results:The exploratory factor analysis extracted 6 common factors(family beliefs, family spirit, family connection, family resources, family communication, family collaboration) with 32 items.Confirmatory factor analysis showed that the model fit well( χ2/ df=2.67, RMSEA=0.025, CFI=0.98, GFI=0.90, IFI=0.98, RMR=0.031). The cronbach's α coefficient of the total scale was 0.96, and 0.82-0.92 for the dimensions.The 2-week retest reliability was 0.99.The total scale score was positively correlated with the validity scale (family resilience scale) ( r=0.882, P<0.001). Conclusion:The family resilience scale for patients with stroke has good reliability and validity and can be used to assess the family resilience of patients with stroke.

Objective To propose a new evaluation system and evaluate the application value of diabetic retinopathy ( DR) intelligence assisted diagnostic technology based on fundus photography. Methods By using the diagnostic test method,an evaluation system of DR intelligent diagnostic technology based on fundus photography was established. The fundus photographs of 331 diabetic patients (662 eyes) with DR screening were collected in the First Affiliated Hospital of Huzhou University from January 2017 to October 2018. The results of experts ' diagnosis and intelligence assisted diagnosis were compared and evaluated. The evaluation system includes primary evaluation, intermediate evaluation and advanced evaluation. The primary evaluation is the consistency of non-DR ( NDR) in all diabetic patients receiving DR-assisted diagnostic techniques;the intermediate evaluation is the diagnosis consistency of DR lesion degree in patients diagnosed with DR (grade 1-4);the advanced evaluation is the diagnosis consistency of DR classification ( grade 0 -4 ) in all diabetic patients receiving DR-assisted diagnostic techniques. The intermediate evaluation includes two evaluation methods. The main evaluation indicators include sensitivity,specificity and Kappa value. Results Based on experts ' diagnosis, NDR accounted for 22. 7％;mild non-proliferative DR (NPDR),moderate NPDR,and severe NPDR accounted for 19. 9％,18. 7％ and 25. 7％,respectively;proliferative DR( PDR) accounted for 13. 0％. Based on intelligence diagnostic system,NDR accounted for 25. 8％;mild NPDR, moderate NPDR and severe NPDR accounted for 19. 7％,19. 3％ and 22. 8％,respectively;proliferative DR( PDR) accounted for 12. 4％. Based on evaluation system in the paper,the sensitivity,specificity and Kappa value in primary evaluation were 91. 4％, 84. 7％ and 0. 72;the sensitivity, specificity and Kappa value in intermediate evaluation method one were 88. 4％,91. 1％ and 0. 79;the sensitivity, specificity and Kappa value in intermediate evaluation method two were 80. 5％,93. 3％ and 0. 75;the Kappa value in advanced evaluation was 0. 62. Conclusions The evaluation system can be applied to the evaluation of DR intelligent diagnostic technology,and the evaluation result can be used as the basis for the selection of DR intelligent diagnosis application scene.

Objective To retrospectively analyze the injury characteristics of victims and treatment strategies in the explosion accident on the 17th May 2018 in Xixia county (Xixia "May 17th" explosion accident). Methods Based on the practice featured in pre-hospital emergency of Henan province and Nanyang city Emergency Center in the explosion accident, a retrospective analysis for the Level Three medical rescue was conducted, where a total of thirteen survived victims in Xixia "May 17" explosion accident were studied retrospectively. The data included the gender, age, burned extent and depth of the patients, burns complicated by trauma, complication of burn, respiratory function maintenance, resuscitation during shock stage, skin grafting with excision and scab. Furthermore, the data of organ function and the effect of the 90-day comprehensive treatment for the burned victims wereanalyzed. Results completion the Level Three treatment on time, which was depended on the leading role played by the regional trauma centers was the main rescuing mode of the work in Xixia county, where the primary and secondary treatments were the key parts. The three-level treatment model includes: the local hospital acts as a level-one emergency medical institution, county hospitals function as secondary emergency medical institutions, and other higher medical institutions are the tertiary first aid medical institutions. The pre-hospital and in-hospital emergency procedures were initiated immediately after the large-scale explosive burn being identified, the key to the successfully rescue was to set up a comprehensive treatment team for burns and trauma. Rescue team should involve burn department and other related departments, including the departments of emergency, general surgery, orthopedic, thoracic surgery, neurosurgery, plastic surgery, intensive care unit, blood transfusion unit, anesthesiology, and interventional radiology, etc. All the thirteen burned patients were male, with inhalation injury, blast injury, hemopneumothorax, brain injury, bone fractures, and etc. Eight of them (61.54%) had multiple organ dysfunction syndrome (MODS). MODS mainly involved respiratory, circulatory, liver, gastrointestinal tract, kidney and coagulation function. With the multi-discipline treatment, the wound of 6 severely-burned patients started healing and can be discharged after keeping the patency of airway, applying resuscitation fluid and comprehensive treatments such as debridement and dressing change. Among 7 patients with extensive deep burns, one case with skull-based fracture, open craniocerebral, extensive intracranial hemorrhage and hemopneumothorax, died 9 hours later. Another case died within 24 hours after injury due to obvious exudation on the site of early incision and relaxation of wound. The escharotomy, micro-dermis and allograft skin transplantation were carried out for five cases with extensive deep burns from the 4th day after the recovery of shock. One week later, the second stage of microsphere skin transplantation was performed. But all died of sepsis or fungal infection. Conclusions MODS and infection often occur during the course especially for patients with extensive and deep burns due to the great explosion in Xixia county, most of whom were accompanied with MODS and infection. Therefore, assembling multi-discipline team for treating the group of explosively-burned patients can increase the survival rate and reduce the possibility of disability.

Objective To evaluate the effect of 3D printing models applied to Medical Imaging Di-agnosis Undergraduate Teaching. Methods Students in the year 2012/2013 of Shanghai Jiao Tong Univer-sity School of Medicine stomatology specialty were chosen for this study, including 38 students in the exper-imental group (2013) and 40 students in the control group (2012). All of them were taught by the same group of teachers, including 28 core curriculum hours and 5 practice class hours. 3D printing technology with PPT was applied to the experimental group in the medical imaging diagnostic teaching, and conventional teaching including PPT and usual models in the control group. Medical students were given a test about cardiovascular system and tasked with completion of drawing hand and foot bones. Students in experimental group were also asked to complete a questionnaire about their experience. Results The questionnaire showed that 3D printing teaching molds with PPT was of great significance to improve the students interest in learning imaging anatomy, to meet the vast majority of students' learning requirements, and to achieve satis-factory results. The average scores of the circulatory system test in the experimental group were higher than that of the control group [(8.32 ±2.352) vs. (6.15 ±1.284), P<0.05)]. Students in experimental group per-formed better than students in the control group on the Locomotor system test [(6.81 ±1.347] vs. (3.84 ± 0.985), P<0.01]. Conclusions 3D printing mold combined with PPT teaching method can promote the med-ical imaging anatomy structure, learning effect and teaching quality, and has practical value in the under-graduate teaching of medical imaging diagnosis.

Objective To analyze the clinical features of 6 patients with imported schistosomiasis mansoni,including the epidemic history,clinical manifestations,laboratory tests and therapeutic effect,so as to provide references for improving the levels of diagnosis and treatment of physicians. Methods The clinical data of 6 patients with imported schistosomiasis mansoni from January 2009 to July 2016 were collected and analyzed. Results All the 6 imported patients with schistosomiasis mansoni had a clear history of cercarial infested water exposure. The main manifestations were continuous fever and eosinophilia. Three (50%)patients were accompanied with diarrhea. Anti-Schistosoma japonicum IgG antibody were cross positive in 2(33.3%)pa-tients,while live eggs of S. mansoni were explored in intestinal mucosa specimens of all the patients. CD3+CD8+T cell ratio was decreased significantly but B cell ratio was elevated in all the patients,and the main immunoglobulin of the patients was IgG. Hydroperitoneum and splenomegaly signs were discovered by abdominal ultrasonography in 16.6%(1/6)of the patients.

Objective Toinvestigateantimicrobialresistanceamonggram-positivecocciinChinain 2013.Methods Retrospectivestudy.FromJune2013toDecember2013,1663consecutiveandnon-repetitive gram-positive cocci were collected from 15 teaching hospitals. The minimal inhibitory concentration ( MIC) of antibacterial agents was determined by agar dilution method. A retrospective study was conducted on rates of resistance to antimicrobial agents. The prevalence of penicillin-resistant Streptococcus pneumoniae ( PRSP) between children and adult patients and the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) between elder group and younger adult patients were compared using chi-square test. Results The prevalence of PRSP in children below 3 years old ( 72. 9%, 51/70 ) was higher than adult patients (55. 2%, 106/192) (χ2 =6. 653,P<0. 05). About 94. 9%(261/275) and (92. 7%,255/275) of S. pneumonia were resistant to erythromycin and clindamycin. All S. pneumoniae strains were susceptible to teicoplanin, vancomycin, linezolid, tigecycline and daptomycin. Penicillin still showed very high activity against Streptococcus spp. β-Hemolytic group. More than 60% of Streptococcus spp.β-Hemolytic group were resistant to erythromycin, clindamycin and tetracyclines. The prevalence of MRSA and methicillin-resistant coagulase-negative Staphylococci(MRCoNS) was 39. 7%(229/576) and 80. 6%(224/278), respectively. The MRSA prevalence ranged from 24. 2% to 70. 0% in different regions. About 52. 6%( 100/190 ) of Staphylococcus aureus from respiratory tract specimens, 38. 5%(40/104)of Staphylococcus aureus from blood samples, and 29. 7%(58/195) of Staphylococcus aureus from wound and pus were resistant to methicillin. The prevalence of MRSA in elder group ( 48. 6%, 84/173 ) was higher than that in younger adult patients (35. 7%, 144/403)(χ2 =8. 322,P <0. 05). The susceptibility rates of MRSA to chloramphenicol and trimethoprim/sulfamethoxazole were 86. 4% ( 244/228 ) and 94. 7% ( 237/228 ) , respectively. Susceptibility rates to gentamycin, erythromycin, clindamycin, tetracyclines, rifampicin and quinolones were ranged from 15. 8% to 59. 6%. All Staphylococci isolates were susceptible to teicoplanin, vancomycin, linezolid, daptomycin and tigecycline. All Enterococcus isolates were susceptible to daptomycin and tigecycline. All E. faecalis ( 158/158 ) and 96. 4% ( 133/138 ) of E. faecium were susceptible to teicoplanin. About 98. 0% ( 150/153 ) of E. faecalis and 97. 1% ( 145/138 ) of E. faecium were susceptible to linezoild. About 45. 8% (70/153) of E. faecalis and 60. 9% (84/138) of E. faecium were resistant to gentamycin with a high concentration. The susceptibility of E. faecalis to all the antibiotics tested exceptchloramphenicolandtetracyclinewashigherthanthatofE.faecium.Conclusions Basedon different age groups and regions, the resistance rates of Gram-positive cocci are different. Teicoplanin, vancomycin, tigecycline, daptomycin, linezolid and tedizolid showed very high activity against Gram-positive cocci. (Chin J Lab Med,2015,38:373-381)

Hematogenous metastasis is common in lung cancer, and except for small cell lung cancer and melanoma, tumors with extensive metastasis seldom involve the prostate. The treatment of lung adenocarcinoma with prostate metastasis relies mainly on systemic chemotherapy with rigorous treatment of the primary lesions and metastatic palliative radiotherapy. Comprehensive treatment integrating traditional Chinese medicine may improve the quality of life of the patients.

BACKGROUNDThe Study for Monitoring Antimicrobial Resistance Trends program monitors the activity of antibiotics against aerobic and facultative Gram-negative bacilli (GNBs) from intra-abdominal infections (IAIs) in patients worldwide.

METHODSIn 2011, 1 929 aerobic and facultative GNBs from 21 hospitals in 16 cities in China were collected. All isolates were tested using a panel of 12 antimicrobial agents, and susceptibility was determined following the Clinical Laboratory Standards Institute guidelines.

RESULTSAmong the Gram-negative pathogens causing IAIs, Escherichia coli (47.3%) was the most commonly isolated, followed by Klebsiella pneumoniae (17.2%), Pseudomonas aeruginosa (10.1%), and Acinetobacter baumannii (8.3%). Enterobacteriaceae comprised 78.8% (1521/1929) of the total isolates. Among the antimicrobial agents tested, ertapenem and imipenem were the most active agents against Enterobacteriaceae, with susceptibility rates of 95.1% and 94.4%, followed by amikacin (93.9%) and piperacillin/tazobactam (87.7%). Susceptibility rates of ceftriaxone, cefotaxime, ceftazidime, and cefepime against Enterobacteriaceae were 38.3%, 38.3%, 61.1%, and 50.8%, respectively. The leastactive agent against Enterobacteriaceae was ampicillin/sulbactam (25.9%). The extended-spectrum β-lactamase (ESBL) rates among E. coli, K. pneumoniae, Klebsiella oxytoca, and Proteus mirabilis were 68.8%, 38.1%, 41.2%, and 57.7%, respectively.

CONCLUSIONSEnterobacteriaceae were the major pathogens causing IAIs, and the most active agents against the study isolates (including those producing ESBLs) were ertapenem, imipenem, and amikacin. Including the carbapenems, most agents exhibited reduced susceptibility against ESBL-positive and multidrug-resistant isolates.
