Objective To assess the efficacy and safety of ascending aorta banding technique combined with typeⅠhybrid aortic arch repair for the aortic arch diseases. Methods The clinical data of patients undergoing ascending aorta banding technique combined with type Ⅰ hybrid arch repair for aortic arch diseases from March 2019 to March 2022 in Beijing Anzhen Hospital were retrospectively analyzed. The technical success, perioperative complications and follow-up results were evaluated. Results A total of 44 patients were collected, including 35 males and 9 females, with a median age of 63.0 (57.5, 64.6) years. The average EuroSCORE Ⅱ score was 8.4%±0.7%. The technical success rate was 100.0%. All patients did not have retrograde type A aortic dissection and endoleaks. One patient died of multiple organ failure 5 days after operation, the in-hospital mortality rate was 2.3%, and the remaining 43 patients survived and were discharged from hospital. The median follow-up period was 14.5 (6-42) months with a follow-up rate of 100.0%. One patient with spinal cord injury died 2 years after hospital discharge. One patient underwent thoracic endovascular aortic repair at postoperative 3 months due to new entry tears near to the distal end of the stent. Conclusion Ascending aorta banding combined with typeⅠhybrid arch repair for the aortic arch diseases does not need cardio-pulmonary bypass. Ascending aorta banding technique strengthens the proximal anchoring area of the stent to avoid risks such as retrograde type A dissection, endoleak and migration. The operation owns small trauma, rapid recovery, low mortality and a low rate of reintervention, which may be considered as a safe and effective choice in the treatment of the elderly, high-risk patients with complex complications.

[Objective] To explore the expression of Nectin-4 in invasive bladder urothelial carcinoma (BUC) tissue and its clinical significance, so as to provide reference for clinical diagnosis and treatment of BUC. [Methods] Nectin-4 expression in 60 cases of invasive BUC and 40 cases of chronic inflammation of bladder mucosa was detected with immunohistochemical staining (IHC) and RNAscope.The results of the two methods were analyzed and compared, and the relationship between the two methods and the clinicopathological characteristics of invasive BUC was discussed.The correlation between the protein expression of Nectin-4 in BUC tissues, human epidermal growth factor receptor 2 (Her-2) and programmed death factor ligand 1 (PD-L1) was analyzed. [Results] The positive protein expression rates of Nectin-4 detected by IHC were 78.33%(47/60) and 17.50% (7/40) in the invasive BUC group and inflammatory group, respectively, while the positive mRNA expression rates of Nectin-4 detected by RNAscope were 83.33% (50/60) and 12.50% (5/40), respectively.The Kappa values of Nectin-4 in the invasive BUC group and inflammatory group were 0.732 and 0.610, respectively, with general consistency.The protein expression of Nectin-4 in invasive BUC was correlated with muscular invasion, histological grade, vascular thrombus, lymph node metastasis and clinical stage (P<0.05). The mRNA expression of Nectin-4 in invasive BUC was correlated with max tumor diameter, muscular invasion, histological grade, vascular thrombus, lymph node metastasis and clinical stage (P<0.05). The high expression of Nectin-4 in invasive BUC was positively correlated with the expression of Her-2 (P=0.002), but not with the expression of PD-L1 (P>0.05). [Conclusion] Nectin-4 is highly expressed in invasive BUC, and is usually associated with the pathological parameters of poor prognosis.Detection of Nectin-4 expression will help to guide clinical diagnosis and treatment.

This article inherited and summarized the application of Professor Tang Xudong's"New Eight Principles in the Syndrome Differentiation and Treatment of Spleen and Stomach Diseases"(abbreviated as"New Eight Principles")in the field of chronic liver disease.It believed that chronic liver disease should be distinguished from the four aspects of"zangfu organs-qi and blood-deficiency and excess-cold and heat".The differentiation of zangfu organs is mainly focused on regulating the liver and spleen,while also taking into account other organs;the differentiation of qi and blood emphasizes the knowing of its excess and deficiency,and the administrative levels of the disease;the differentiation of deficiency and excess is based on the principle of qi-deficency and blood-stasis,and strengthens body resistance and eliminating evil;for the differentiation of cold and heat,liver-gallbladder dampness-heat syndrome is the most common,but do not forget the liver cold syndrome.On this basis,Tongjiang theory is used as the treatment legislation,making it easier to be mastered,and guiding the prescription and medication of chronic liver disease throughout the entire stage,which can achieve good efficacy.

Objective To explore the adverse pregnancy outcomes of gestational diabetes mellitus (GDM) patients with different conception methods,and to construct a risk prediction model.Methods A ret-rospective cohort study was carried out to analyze the clinical data of 1453 cases of GDM patients who re-ceived regular prenatal care and delivery in the obstetrics department of the First People's Hospital of Yunnan Province from January 2018 to August 2022.A total of 436 patients with GDM who underwent in vitro fertili-zation-embryo transfer (IVF-ET) were served as the observation group,1017 GDM patients with natural ges-tation during the same period were selected as the control group.Chi-square test and t-test were used to com-pare the basic data,weight change,blood glucose reaching standard rate,maternal and infant pregnancy out-comes and related complications between the two group.The risk factors causing adverse pregnant outcomes were analyzed after controlling the confounding variables by adopting multivariate logistic regression.The pre-diction model was constructed according to the regression coefficient weight of each risk factor.The receiver operating characteristic (ROC) curve and the area under the curve (AUC) were used to evaluate the predictive efficiency of each independent risk factor and combined predictive factors.Results IVF-ET was an independ-ent risk factor for the first cesarean section (OR=1.809,95%CI:1.339-2.442),preterm birth (OR=1.622,95%CI:1.090-2.413),postpartum hemorrhage (OR=2.377,95%CI:1.406-4.018),adherent placenta (OR=1.971,95%CI:1.211-3.209),low birth weight infant (OR=2.232,95%CI:1.354-3.680) in the pa-tients with GDM (P<0.05).A combined prediction model was established by parity,age,fetus number,ges-tational weight gain,IVF-ET and scar uterus.The combined prediction probability was P=eLogit(P)/(1+eLogit(P)),Logit(P)=β1X1+β2X2+…+βnXn.The combined prediction efficacy of this study model for pre-term birth,cesarean section and low birth weight infants was good,AUC was approximately 0.8,which was greater than AUC of each independent risk factor.Conclusion The combined model of parity,age,fetus num-ber,gestational weight gain,IVF-ET and scar uterus has a certain predictive value for the risk of cesarean sec-tion,preterm birth and low birth weight infant in the patients with GDM.

Objective To compare the clinical efficacies among three surgical methods in the treatment of stage Ⅲ Kümmell's disease without neurological symptoms.Methods A total of 71 patients with stage Ⅲ Kümmell's disease without neurological symptoms admitted and treated in the orthopedics department of Af-filiated Yueyang Hospital of Hunan Normal University from September 2019 to April 2022 were selected and divided into three groups:29 cases in the percutaneous vertebroplasty (PVP) group (group A),19 cases in the percutaneous pedicle screw+lesioned vertebral PVP group (group B) and 21 cases in the percutaneous bone cement screw combined with lesioned vertebral PVP group (group C) according to the operation methods.The imaging,perioperative and follow-up indexes were compared among the three groups.Results All patients successfully completed the operation,no serious complications occurred after operation,and the follow-up time was more than 1 year.The sagittal position index (SI value) in the affected vertebra,visual analogue scale (VAS) score and Oswestry Disability Index (ODI) score at each time point (postoperative 1,3 months,1 year) after surgery in the group A were improved compared with before operation (P<0.05).The affected vertebra SI value,kyphosis Cobb angle,spinal canal stenosis rate,VAS score and ODI score at postoperative time points in the group B and C were improved compared with before operation (P<0.05).The affected ver-tebra SI value,kyphosis Cobb angle,spinal canal stenosis rate and ODI score at postoperative time points in the group B and C all were superior to those in the group A (P<0.05),while the affected vertebra SI value,kyphosis Cobb angle and spinal canal stenosis rate in postoperative 1 year in the group C were superior to those in the group B (P<0.05).The operative time,intraoperative bleeding volume,postoperative hospitaliza-tion duration and affected vertebral cement injection volume in the group A were significantly less than those in the group B and C (P<0.05).The operation time in the group B was less than that in the group C (P<0.05).Conclusion The three surgical methods for the treatment of stage Ⅲ Kümmell's disease without neu-rological symptoms all could relieve the symptoms and restore the function.The two surgical methods of pedi-cle screw reduction could more effectively restore the height of the affected vertebra,correct kyphosis malfor-mation and improve spinal stenosis than PVP alone.The pedicle screw has more advantages in maintaining mechanical support and stability after bone cement reinforcement.

OBJECTIVE To evaluate the efficacy of intranasal branches neurotomy of vidian nerve in the treatment of persistent moderate to severe allergic rhinitis. METHODS Cases diagnosed as persistent moderate-severe allergic rhinitis in our department were collected. those treated with branches neurotomy of vidian nerve were selected as the treatment group,and those treated with conservative medicine were selected as the control group. The visual analogue scale(VAS),rhinoconjunctivitis quality of life questionnaire(RQLQ),Nitric oxide in nose(nNO) and medication score evaluation of two groups of cases were evaluated respectively short-term(<1 year),medium-term(1 to 3 years) and long-term prognosis of outcome(3 to 5 years). RESULTS The short-term,mid-term and long-term postoperative VAS(2.26±0.75,2.30±0.63,2.49±0.57),RQLQ(0.55±0.11,0.55±0.11,1.00±0.12),nNO[(464.62±75.84)ppb,(378.63±110.21)ppb,(368.23±104.25)ppb]and medication scores (2.50±1.03,2.54±0.99,2.95±0.93) were significantly lower than those before operation[6.76±0.58,3.35±0.40,(696.64±132.69)ppb,5.17±1.50)]. The VAS,RQLQ,nNO and medication scores of the control group were lower than those of the control group at the corresponding time points(all P<0.05). One patient developed blindness in the right eye after interventional treatment due to epistaxis 21 days after operation,but no serious complications directly related to intranasal branches neurotomy of vidian nerve occurred. CONCLUSION The branches neurotomy of vidian nerve have a positive outcome in short,medium and long-term for persistent moderate to severe allergic rhinitis,the operation is safe and effective.

Objective:To establish a risk prediction model of liver failure after liver resection for hepatocellular carcinoma.Method:A retrospective case-control study was designed. Clinical data and laboratory results, including gender, age, and preoperative 18 laboratory indicators, were collected from 320 patients with hepatocellular carcinoma undergoing liver resection in Eastern Hepatobiliary Surgery Hospital Affiliated to Naval Medical University from January 1, 2013 to December 31, 2023. According to the surgical time, 252 cases in the training cohort were divided into 62 and 190 cases with and without postoperative liver failure, respectively. Of the 68 cases in validation cohort, 34 developed postoperative liver failure and 34 did not. Binary Logistic regression analysis was used to conduct univariate analysis of gender, age, and 18 preoperative laboratory indicators, and multivariate analysis was carried out for significant results to determine the influencing factors of liver failure after liver resection for hepatocellular carcinoma, and Logistic regression model was established.Result:In the training cohort, indicators significantly associated with liver failure after liver resection for hepatocellular carcinoma included age ( P=0.016), platelets ( P=0.005), prealbumin ( P<0.001), and alkaline phosphatase ( P<0.001). Logistic regression was used to construct a nomogram model and draw a calibration curve by combining these four indicators. In the training cohort, the nomogram model showed good discriminability in predicting the risk of liver failure after hepatectomy for hepatocellular carcinoma. The area under the curve of was 0.82 (95% CI 0.76-0.88), and the sensitivity was 73% and specificity was 80% when the optimal cut-off value was 0.2646. In the validation cohort, the predictive performance of the nomogram model was comparable to that of the training cohort, with an area under the curve of 0.81 (95% CI 0.71-0.92), sensitivity of 82%, and specificity of 77%. Conclusion:Preoperative platelet and prealbumin decreases, alkaline phosphatase increases, and elderly patients are prone to liver failure after liver resection. The nomogram model constructed with preoperative test data has shows good discriminatory ability and accuracy in predicting liver failure after liver resection for hepatocellular carcinoma.

Chronic refractory wound (CRW) is one of the most challengeable issues in clinic due to complex pathogenesis, long course of disease and poor prognosis. Experts need to conduct systematic summary for the diagnosis and treatment of CRW due to complex pathogenesis and poor prognosis, and standard guidelines for the diagnosis and treatment of CRW should be created. The Guideline forthe diagnosis and treatment of chronic refractory wounds in orthopedic trauma patients ( version 2023) was created by the expert group organized by the Chinese Association of Orthopedic Surgeons, Chinese Orthopedic Association, Chinese Society of Traumatology, and Trauma Orthopedics and Multiple Traumatology Group of Emergency Resuscitation Committee of Chinese Medical Doctor Association after the clinical problems were chosen based on demand-driven principles and principles of evidence-based medicine. The guideline systematically elaborated CRW from aspects of the epidemiology, diagnosis, treatment, postoperative management, complication prevention and comorbidity management, and rehabilitation and health education, and 9 recommendations were finally proposed to provide a reliable clinical reference for the diagnosis and treatment of CRW.

The biological samples of oral genetic diseases and rare diseases are extremely precious. Collecting and preserving these biological samples are helpful to elucidate the mechanisms and improve the level of diagnose and treatment of oral genetic diseases and rare diseases. The standardized construction of biobanks for oral genetic diseases and rare diseases is important for achieving these goals. At present, there is very little information on the construction of these biobanks, and the standards or suggestions for the classification and coding of biological samples from oral and maxillofacial sources, and this is not conducive to the standardization and information construction of biobanks for special oral diseases. This consensus summarizes the background, necessity, principles, and key points of constructing the biobank for oral genetic diseases and rare diseases. On the base of the group standard "Classification and Coding for Human Biomaterial" (GB/T 39768-2021) issued by the National Technical Committee for Standardization of Biological Samples, we suggest 76 new coding numbers for different of biological samples from oral and maxillofacial sources. We hope the consensus may promote the standardization, and smartization on the biobank construction as well as the overall research level of oral genetic diseases and rare diseases in China.
