With the increasing proportion of human papilloma virus(HPV)infection in the pathogenic factors of oro-pharyngeal cancer,a series of changes have occurred in the surgical treatment.While the treatment mode has been im-proved,there are still many problems,including the inconsistency between diagnosis and treatment modes,the lack of popularization of reconstruction technology,the imperfect post-treatment rehabilitation system,and the lack of effective preventive measures.Especially in terms of treatment mode for early oropharyngeal cancer,there is no unified conclu-sion whether it is surgery alone or radiotherapy alone,and whether robotic minimally invasive surgery has better func-tional protection than radiotherapy.For advanced oropharyngeal cancer,there is greater controversy over the treatment mode.It is still unclear whether to adopt a non-surgical treatment mode of synchronous chemoradiotherapy or induction chemotherapy combined with synchronous chemoradiotherapy,or a treatment mode of surgery combined with postopera-tive chemoradiotherapy.In order to standardize the surgical treatment of oropharyngeal cancer in China and clarify the indications for surgical treatment of oropharyngeal cancer,this expert consensus,based on the characteristics and treat-ment status of oropharyngeal cancer in China and combined with the international latest theories and practices,forms consensus opinions in multiple aspects of preoperative evaluation,surgical indication determination,primary tumor re-section,neck lymph node dissection,postoperative defect repair,postoperative complication management prognosis and follow-up of oropharyngeal cancer patients.The key points include:① Before the treatment of oropharyngeal cancer,the expression of P16 protein should be detected to clarify HPV status;② Perform enhanced magnetic resonance imaging of the maxillofacial region before surgery to evaluate the invasion of oropharyngeal cancer and guide precise surgical resec-tion of oropharyngeal cancer.Evaluating mouth opening and airway status is crucial for surgical approach decisions and postoperative risk prediction;③ For oropharyngeal cancer patients who have to undergo major surgery and cannot eat for one to two months,it is recommended to undergo percutaneous endoscopic gastrostomy before surgery to effectively improve their nutritional intake during treatment;④ Early-stage oropharyngeal cancer patients may opt for either sur-gery alone or radiation therapy alone.For intermediate and advanced stages,HPV-related oropharyngeal cancer general-ly prioritizes radiation therapy,with concurrent chemotherapy considered based on tumor staging.Surgical treatment is recommended as the first choice for HPV unrelated oropharyngeal squamous cell carcinoma(including primary and re-current)and recurrent HPV related oropharyngeal squamous cell carcinoma after radiotherapy and chemotherapy;⑤ For primary exogenous T1-2 oropharyngeal cancer,direct surgery through the oral approach or da Vinci robotic sur-gery is preferred.For T3-4 patients with advanced oropharyngeal cancer,it is recommended to use temporary mandibu-lectomy approach and lateral pharyngotomy approach for surgery as appropriate;⑥ For cT1-2N0 oropharyngeal cancer patients with tumor invasion depth＞3 mm and cT3-4N0 HPV unrelated oropharyngeal cancer patients,selective neck dissection of levels ⅠB to Ⅳ is recommended.For cN+HPV unrelated oropharyngeal cancer patients,therapeutic neck dissection in regions Ⅰ-Ⅴ is advised;⑦ If PET-CT scan at 12 or more weeks after completion of radiation shows intense FDG uptake in any node,or imaging suggests continuous enlargement of lymph nodes,the patient should undergo neck dissection;⑧ For patients with suspected extracapsular invasion preoperatively,lymph node dissection should include removal of surrounding muscle and adipose connective tissue;⑨ The reconstruction of oropharyngeal cancer defects should follow the principle of reconstruction steps,with priority given to adjacent flaps,followed by distal pedicled flaps,and finally free flaps.The anterolateral thigh flap with abundant tissue can be used as the preferred flap for large-scale postoperative defects.

Objective: To investigate the clinical features, treatment regime, and outcome of pediatric acute myeloid leukemia (AML) with DEK-NUP214 fusion gene. Methods: The clinical data, genetic and molecular results, treatment process and survival status of 7 cases of DEK-NUP214 fusion gene positive AML children admitted to the Pediatric Blood Diseases Center of Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences from May 2015 to February 2022 were analyzed retrospectively. Results: DEK-NUP214 fusion gene positive AML accounted for 1.02% (7/683) of pediatric AML diagnosed in the same period, with 4 males and 3 females. The age of disease onset was 8.2 (7.5, 9.5) years. The blast percentage in bone marrow was 0.275 (0.225, 0.480), and 6 cases were M5 by FAB classification. Pathological hematopoiesis was observed in all cases except for one whose bone marrow morphology was unknown. Three cases carried FLT3-ITD mutations, 4 cases carried NRAS mutations, and 2 cases carried KRAS mutations. After diagnosis, 4 cases received IAE induction regimen (idarubicin, cytarabine and etoposide), 1 case received MAE induction regimen (mitoxantrone, cytarabine and etoposide), 1 case received DAH induction regimen (daunorubicin, cytarabine and homoharringtonine) and 1 case received DAE induction regimen (daunorubicin, cytarabine and etoposide). Complete remission was achieved in 3 cases after one course of induction. Four cases who did not achieved complete remission received CAG (aclarubicin, cytarabine and granulocyte colony-stimulating factor), IAH (idarubicin, cytarabine and homoharringtonine), CAG combined with cladribine, and HAG (homoharringtonine, cytarabine and granulocyte colony-stimulating factor) combined with cladribine reinduction therapy, respectively, all 4 cases reached complete remission. Six patients received hematopoietic stem cell transplantation (HSCT) after 1-2 sessions of intensive consolidation treatment, except that one case was lost to follow-up after complete remission. The time from diagnosis to HSCT was 143 (121, 174) days. Before HSCT, one case was positive for flow cytometry minimal residual disease and 3 cases were positive for DEK-NUP214 fusion gene. Three cases accepted haploid donors, 2 cases accepted unrelated cord blood donors, and 1 case accepted matched sibling donor. The follow-up time was 20.4 (12.9, 53.1) months, the overall survival and event free survival rates were all 100%. Conclusions: Pediatric AML with DEK-NUP214 fusion gene is a unique and rare subtype, often diagnosed in relatively older children. The disease is characterized with a low blast percentage in bone marrow, significant pathological hematopoiesis and a high mutation rate in FLT3-ITD and RAS genes. Low remission rate by chemotherapy only and very high recurrence rate indicate its high malignancy and poor prognosis. Early HSCT after the first complete remission can improve its prognosis.

Objective:To analyze the application value of narrative education model in clinical teaching of nurses in operating room.Methods:A total of 90 nursing students in the Department of Operating Room, Shanghai Tenth People's Hospital from January 2018 to January 2020 were selected as the research objects and randomly divided into observation group and control group, 45 in each group. The control group was taught by traditional mentoring method, and the observation group was taught by narrative education model. The two groups of nursing students practiced for 4 weeks. After the teaching, the scores of theoretical knowledge and operation were compared between the two groups. The scores of career identity scale and caring ability evaluation scale of the two groups were compared, the scores of each dimension of Chinese registered nurse core competence scale (CIRN) were evaluated, and the feedback of the two groups of nursing students on the teaching methods was analyzed. SPSS 22.0 was used to conduct t-test and chi-square test. Results:The scores of theoretical knowledge and operation in the observation group were (94.52±5.34) points and (88.67±3.98) points, respectively, which were significantly higher than those [(85.67±5.26), (82.24±4.16)] in the control group ( t=7.92, 7.49, all P<0.001). The scores of professional identity scale and caring ability evaluation scale in the observation group were (39.12±5.12) points and (193.14±11.24) points, respectively, which were significantly higher than those [(34.21±4.23), (180.23±11.35)] in the control group ( t=4.96, 5.42, all P<0.001). The scores of various dimensions of CIRN in the observation group were significantly higher than those in the control group ( t=4.72, 7.57, 4.13, 4.66, 6.19, 4.27, 5.48, all P<0.001). The feedback of nursing students in the observation group on teaching methods was significantly better than that in the control group ( χ2=4.29, 6.48, 12.26, 4.44, 7.60, 5.03, P<0.05). Conclusion:Narrative education model can significantly improve the internship effect of operating room interns, with clinical value.

"Kidney essence" is a profound concept in the theory of traditional Chinese medicine. But its biological basis is unknown until now, resulting in the therapeutic effects of traditional Chinese drugs on reinforcing kidney for supplementing essence hard to be evaluated. This study aimed, to explore the potential biological basis and mechanism of traditional Chinese drugs of reinforcing kidney for supplementing essence on diseases related to deficiency of kidney essence through network pharmacology analysis on the intersection of targets of drugs and diseases. The targets for ingredients in Rehmanniae radix praeparata (RRP), Polygoni multiflori radix praeparata (PMRP) and Polygonati rhizome (PR) were gathered from TCMSP and TCMID database. Osteoporosis, Alzheimer's disease, anemia, infertility and oligospermia targets were collected from OMIM and DisGeNET database. Drug-compound-target-disease (DCTD) network was established with Cytoscape 3.6.1 software, then Clue GO and DAVID database was used to acquire the annotation about GO terms and signaling pathways. Natural aging mice, an acknowledged syndrome model of deficiency of kidney essence, and RRP were used to verify the predictive targets by Western blot analysis. All animal experiments were conducted in accordance with the international guidelines and regulations for the care and use of animals. DCTD network showed that the intersection of drugs and diseases included 175 common targets. After topology analysis, 71 key were screened out targets which were associated with GO annotation exhibited that biological processes (including transcription regulation, RNA metabolism regulation, and DNA-dependent transcription regulation), cell composition (including nuclear lumen, organelle lumen, and membrane closure lumen), molecular function (including transcription regulation, transcription factor activity, and enzyme binding), and signaling pathway (including peroxisome proliferator-activated receptor alpha (PPARα), mitogen-activated protein kinase (MAPK), hypoxia-inducible factor 1 (HIF-1), erythropoietin (EPO) and other signaling pathways. In natural aging mice, the expressions of HIF-1α, growth factor receptor-bound protein 2 (GRB2), MAPK3, signal transducer and activator of transcription 5A (STAT5A), transcription factor AP-1 (JUN) and proto-oncogene c-Fos (FOS) in EPO pathway were significantly decreased. RRP significantly reversed the decrease of the above targets. Above all, these results indicated that the therapeutic effects of traditional Chinese drugs of reinforcing kidney for supplementing essence on deficiency of kidney essence may be related to the regulation of nuclear transcriptional activity and EPO signaling pathway.

Objective:To retrospectively analyze the experience of our center in the use of marginal donor heart, and to explore the principle of use and risk control of marginal donor heart.Methods:A total of 31 patients with end-stage heart disease underwent orthotopic heart transplantation in our center from January 2018 to December 2018, including 28 cases of pure heart transplantation, 2 cases of combined heart-lung transplantation, and 1 case of combined heart-kidney transplantation. 26 of the 31 cases were marginal donor hearts. These patients were all anastomosed by a double lumen method.Results:The rates of postoperative use of ECMO, IABP and acute rejection were zero in this study. The time of cardiopulmonary bypass in the marginal donor group was significantly longer compared with the conventional donor group( P<0.05), but there was no significant difference between the two groups in terms of hospitalization time, mechanical ventilation time, ICU stay time, abnormal rate of ECG, LVEF and blood biochemical indexes(all P>0.05). The postoperative follow-up rate was 100% in the two groups. One case of combined heart-lung transplantation in the marginal donor group died of multiple organ failure in the first month after surgery. During the postoperative follow-up period, the incidence of moderate to severe tricuspid regurgitation and the incidence of recurrent heart failure were zero in the two groups. There was no significant difference in the incidence of arrhythmia, LVEF, infection and blood biochemical parameters. Conclusion:The application of marginal donor heart has no significant effect on the short-term survival rate and recovery of patients after heart transplantation, but the long-term effect needs further follow-up.

CEUS is a pure blood pool imaging depending on the non-linear effect and strong backscatter of gas-filled microbubbles in blood to obtain contrast-enhanced images.With the advantages of displaying tumor microvascular dynamically and intuitively,CEUS has been widely used for diagnosis and evaluating prognosis of breast cancers.CEUShas high sensitivity and specificity in detecting early breast cancers and identifying sentinel lymph nodes,with wide application prospects in assessing the efficacy of neoadjuvant therapy,predicting molecular typing and targeted therapy of breast cancers.The features of CEUS in breast cancers and the relationships with biomarkers,progresses in assessing neoadjuvant therapy and assisting sentinel lymph node biopsy were reviewed in the article.

OBJECTIVETo investigate the association between clinical outcome and gene mutations in children with Fanconi anemia (FA).

METHODSA retrospective analysis was performed for the clinical data of six children with the same severity of FA and receiving the same treatment. At first, single cell gel electrophoresis and chromosome breakage induced by mitomycin C were performed for diagnosis. Then the gene detection kit for congenital bone marrow failure diseases or complementation test was used for genotyping of FA. Finally the association between the clinical outcome at 3, 6, 9, or 12 months after treatment and gene mutation was analyzed.

RESULTSOf all the six FA children, five had FANCA type disease, and one had FANCM type disease; four children carried two or more FA gene mutations. Among the children with the same severity of FA, those with more FA mutations had a younger age of onset and poorer response to medication, and tended to progress to a severe type.

CONCLUSIONSChildren carrying more than two FA mutations have a poor clinical outcome, and hematopoietic stem cell transplantation should be performed as soon as possible.

OBJECTIVETo design ABC damage variable and positioning system for acetabular fracture and explore the feasibility and clinical practical value of the system through the multi-center analysis of 1122 acetabular fractures.

METHODSAccording to acetabular three-column conception, and pelvic ring lesions damage direction caused by acetabular fracture domino effect and injury degree of proximal femur joint, it defined class A as any column acetabular fracture; class B as any two-column acetabular fracture; class C as front, dome and posterior mixture acetabular fracture. Lower case English letters a, m, p represented front, dome, posterior fracture, respectively. Acetabular damage variables: 1 was simple displaced fractures; 2 was comminuted fractures; 3 was compression fractures. Pelvic ring lesions damage variables: alpha was sacroiliac joints or sacroiliac fracture horizontal separation deflection; beta was sacroiliac joints or sacroiliac fracture vertical separation deflection; gamma was pubic symphysis separation/superior and inferior ramus of pubis fracture deflection; alpha beta gamma delta was compound floating damage. Proximal humerus joint damage variables: I was femoral head fracture; II was femoral neck fracture; II was intertrochanteric fractures of femur; IV was I to III compound fracture. The ABC damage variable positioning system for acetabular fracture was made up by the above-mentioned variables. The statistics from March 1997 to February 2010 showed 1122 cases acetabular fractures with 18 cases of double side acetabular fracture and 1140 cases of acetabular fractures. The pelvics anterior-posterior view, ilium and obturator oblique view, and 2/3D-CT materials were analyzed and researched.

RESULTSEach damage variables distribution situation in 1140 cases of acetabular fracture involved A in 237 cases (20.8%), B in 605 cases (53.1%), C in 298 cases (26.1%);front column fracture in 808 cases(70.9%), dome fracture in 507 cases (44.5%), posterior fracture in 1026 cases (90%). Acetabular variables: variabe 1 in 203 cases of simple displaced fracture (17.8%); variabe 2 in 516 cases of comminuted fracture(45.3%); variabe 3 in 421 cases of compression fracture (36.9%); 249 cases of pelvic ring lesions damage (21.8%), 75 cases femoral head fracture (6.6%); 18 cases of double side acetabular fracture and relative pelvic ring and proximal humerus joint variables (1.58%). Key part and curative effect elements of 1140 cases acetabular fracture: 507 cases of dome or posterior acetabular fracture (44.5%); 421 cases of compression fracture (36.9%); 249 cases of pelvic ring variables (21.8%); 75 cases of proximal humerus joint variables (6.6%); 486 cases of simple Aa/pl/2,Bapl/2 acetabular fracture (42.6% ).

CONCLUSIONCompression fracture, especially defected compression fracture, takes important part in acetabular damage variables, and also presents that acetabular fracture with pelvic ring and proximal femoral damage variables are not rare at all. The relationship of the acetabular fracture damage variables, and its percentage shows the key points and elements in clinical treatment: weight-bearing to dome accounts for 44.5%; compression to defects account for 36.9%, pelvic ring to float accounts for 21.8%; dome fracture to double side fracture account for 6.6%. The system has significant guiding effects on clinic in terms of evaluation of injury severity, anatomic localization, difficulty index, alternative strategy, operative approach, effect of treatment,and prognosis. And the most important thing is that the system creates the comparison of damage variables in same type of fracture and the communication of homo-language and explores a new method.
