Objective:To share our experience of single-port transoral Da Vinci robotic surgery for laryngeal and pharyngeal benign tumors.Methods:Three patients aged over 18 years and diagnosed respectively with epiglottic cyst, aryepiglottic fold cyst and thyroglossal duct cyst at tongue base were included who received operations in Hainan Hospital of Ruijin Hospital affiliated to Shanghai Jiao Tong University School of Medicine (Boao Research Hospital of Hainan) between August 1, 2023 and April 10, 2024. There were 1 male and 2 females, with an average age of 59 years old. The clinical diagnosis of these 3 patients was respectively epiglottic cyst, aryepiglottic fold cyst and thyroglossal duct cyst at tongue base. Intraoperative conversion rate, blood loss, operation time, hospital stay, pain score and swallowing function score were analyzed.Results:All three patients successfully underwent the operations with the single-port Da Vinci robotic system. The clean-contaminated resection rate of the tumors was 100%. The conversion rate was nil. The blood loss was 0-7 ml. The operation time was 5-30 minutes. There were no adverse events such as loosening of teeth and soft tissue abrasions of pharyngeal side wall. The rate of oral feeding within 24 hours after surgery was 100%. No postoperative coughing, bleeding, or dyspnea occurred. The average length of hospital stay was 3.7 days. The VAS score decreased 3 days after surgery compared to 1 day after surgery. The swallowing function recovered 1 month after surgery.Conclusion:The single-port transoral robotic surgery for laryngeal and pharyngeal benign lesions is safe and efficient, with fewer complications.

Objective To compare the efficacy of TightRope loop plate and Endobutton plate in the treatment of acromioclavicular joint dislocation.Methods A retrospective analysis was conducted on 94 patients with acromioclavicular joint dislocation who were treated at this center from March 2021 to February 2023.They were divided into two groups based on different admission date.The Group E(n =47)received Endobutton plate treatment between March 2021 and February 2022,while the Group T(n =47)received TightRope loop plate treatment between March 2022 and February 2023.At the last follow-up,the perioperative indicators,Visual Analogue Scale(VAS),Constant-Murley shoulder joint function scores,and surgical complications were compared between the two groups.Results The surgical time,intraoperative bleeding,incision length,and VAS scores at 7 days after surgery in the Group T were shorter or lower than those in the Group E(P<0.05).There were no statistical differences in the incidence of perioperative nerve injury,internal fixation displacement,clavicle fracture,vascular injury,and infection between the two groups(P>0.05).The subjective and objective scores of Constant-Murley shoulder joint function in both groups at9 months after surgery showed significant improvement compared to preoperative scores(all P =0.000).There was no significant difference in the subjective and objective scores of Constant-Murley shoulder joint function between the two groups at 9 months after surgery(P>0.05).Conclusions The treatment of acromioclavicular joint dislocation with TightRope loop plate ot or Endobutton plate has a significant effect and can effectively improve shoulder joint function.Compared with Endobutton plate,use of TightRope loop plate has minor surgical trauma,less bleeding,and significantly reduced postoperative pain,being more conducive to early functional exercise for patients.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective·To assess the effect of veno-arterial extracorporeal membrane oxygenation(VA-ECMO)treatment on the mortality rate of patients suffering from cardiogenic shock and cardiac arrest in hospital.Methods·A total of 19 patients with cardiogenic shock or cardiac arrest who were treated with VA-ECMO treatment in Suzhou Kowloon Hospital,Shanghai Jiao Tong University School of Medicine from September 2017 to March 2022 were included in the retrospective study.Patients were divided into extracorporeal cardiopulmonary resuscitation(ECPR)group(n=9)and VA-ECMO for cardiogenic shock(E-CS)group(n=10)according to whether cardiac arrest had occurred.The general demographic data,clinical data,Sequential Organ Failure Assessment(SOFA)scores,postoperative complications and prognostic indicators of the two groups of patients were collected.Univariate and multivariate Cox proportional hazard regression analyses were used to evaluate the correlation between each covariate and hospital mortality.Results·Among the included patients,there were 15 males(78.9％),with an average age of 46.5(34.5,61.6)years.The incidence of postoperative complications was as follows:bleeding(47.4％),AKI(36.8％),infection(31.6％),limb ischemia(15.8％)and cerebrovascular accident(5.3％).The duration of VA-ECMO was 4.0(2.0,6.8)days,and the intensive care duration was 11.5(5.8,26.2)days;the ECMO withdrawal success rate was 63.2％,and the hospital mortality was 63.2％.The results of univariate Cox proportional hazard regression analysis showed that AKI(prior to VA-ECMO initiation),postoperative complications of infection and limb ischemia were correlated with the hospital mortality of patients(all P＜0.05).The results of multivariate Cox proportional hazard regression analysis showed that AKI(prior to VA-ECMO initiation),postoperative complications of infection and limb ischemia were also independent risk factors for the hospital mortality of patients(all P＜0.05).Conclusion·For patients with cardiogenic shock and cardiac arrest treated with VA-ECMO,AKI(prior to VA-ECMO initiation),postoperative infection and limb ischemia are independently associated with higher hospital mortality.

Objective:To evaluate the effect of electroacupuncture on the heme oxygenase-1 (HO-1)/PTEN-induced putative kinase 1 (PINK1)/Parkin signaling pathway during acute kidney injury in endotoxemic rats.Methods:Twenty-four SPF healthy male Sprague-Dawley rats, aged 6-8 weeks, weighing 180-220 g, were divided into 4 groups ( n=6 each) by a random number table method: control group(group C), endotoxemia group(group E), acupoint electroacupuncture+ endotoxemia group(group EE), and non-acupoint electroacupuncture+ endotoxemia group(group NE). The endotoxemia model was developed by intraperitoneal injection of lipopolysaccharide 10 mg/kg. The equal volume of normal salinewas injected in group C. LPS 10 mg/kg was intraperitoneally injected in group E. In group EE, 30-min electroacupuncture was performed at bilateral Zusanli and Shenshu acupoints using disperse-dense waves with a frequency of 2/15 Hz to induce slight muscle tremor once a day starting from 5 days before developing the model, and the needle was retained until 6 h after injection. Electroacupuncture was performed at the points 0.5 cm lateral to the acupoints of Zusanli and Shenshu in group NE. The rats were anesthetized at 6 h after lipopolysaccharide injection, and blood samples from the femoral vein were obtained for determination of the serum creatinine (Cr) and urea nitrogen (BUN) concentrations(with a biochemical analyzer) and concentrations of neutrophil gelatinase-associated lipid transport protein (NGAL), interleukin-6 (IL-6), tumor necrosis factor (TNF-α) and kidney injury molecule-1(KIM-1) in serum (by enzyme-linked immunosorbent assay). Then the rats were sacrificed and kidney tissues were taken for determination of histological score of kidneys (HSK, using HE staining) and expression of HO-1, PINK1, Parkin, mitochondrial fusion protein 2(Mfn2), optic atrophy protein 1(OPA1) and mitochondrial dynamic-related protein 1 (Drp1) (by Western blot). Results:Compared with group C, serum concentrations of Cr, BUN, KIM-1, NGAL, IL-6 and TNF-α and HSK score of renal tissues were significantly increased, the expression of HO-1, PINK1, Parkin and Drp1 was up-regulated, and the expression of Mfn2 and OPA1 was down-regulated in E, EE and NE groups ( P<0.05). Compared with group E, serum concentrations of Cr, BUN, KIM-1, NGAL, IL-6 and TNF-α and HSK score of renal tissues were significantly decreased, and the expression of HO-1, PINK1, Parkin, Mfn2 and OPA1 was up-regulated, and Drp1 expression was down-regulated in group EE( P<0.05), and no significant change was found in the parameters mentioned above in group NE ( P>0.05). Conclusions:The mechanism by which electroacupuncture alleviates acute kidney injury is associated with activation of HO-1/PINK1/Parkin signaling pathway in endotoxemic rats.
