Objective To explore the protection effect and mechanism of preoperative ultrasound-guided stellate ganglion block(SGB)on lung in patients undergoing one-lung ventilation(OLV)during thoracoscopic surgery.Methods Eighty-four patients who underwent OLV during thoracoscopic lobectomy at the Affiliated Suzhou Hospital of Nanjing Medical University from January 2021 to April 2022 were selected as research subjects,and the patients were divided into the observation group and control group by using a random number table,with 42 patients in each group.Patients in the observation group received ultrasound-guided SGB before anesthesia induction,while patients in the control group did not undergo puncture procedures.Patients in both groups received the same anesthesia induction and maintenance protocols.Hemodynamic,respiratory and arterial blood gas parameters were recorded at various time points:upon entering the operating room(T0),before OLV(T1),30 minutes after OLV initiation(T2),60 minutes after OLV initiation(T3),completion of surgery(T4),and 30 minutes after extubation(T5).Oxygenation index(OI),intrapulmonary shunt rate(Qs/Qt)and pH values of patients in the two groups were compared at these time points.Venous blood were collected from patients in both groups at T0,T3 and T5,and enzyme-linked immunosorbent assay was employed to measure the levels of surfactant protein-A(SP-A),superoxide dismutase(SOD),malondialdehyde(MDA),interleukin-6(IL-6)and interleukin-10(IL-10).Postoperative SGB-related complications and pulmonary complications within 72 hours were recorded.Results The mean arterial pressure(MAP)and heart rate(HR)in both groups were significantly lower at T,,T2,and T3 compared to T0(P＜0.05);the MAP and HR at T4 and T5 had no statis-tically significant difference compared to those at T0(P＞0.05);there was no significant difference in MAP and HR at other time points(P＞0.05).MAP in the observation group at T1,T2 and T3 was significantly lower than that in the control group(P＜0.05),and HR in the observation group at T2 and T3 was significantly lower than that in the control group(P＜0.05);there were no significant differences in MAP and HR between the two groups at other time points(P＞0.05).There were no significant differences in pulse oxygen saturation(SpO2)between the two groups at T0-T5(P＞0.05).At T2 and T3,peak airway pressure(Ppeak)and respiratory rate(RR)were significantly higher than those at T,and T4,and tidal volume(TV)was significantly lower than that at T,and T4 in both groups(P＜0.05).Ppeak and TV in the observation group at T2 and T3 were significantly lower than those in the control group(P＜0.05);there were no significant differences in Ppeak and TV between the two groups at T1 and T4(P＞0.05).RR and partial pressure of end-tidal carbon dioxide(PetCO2)at T1-T4 showed no significant differences between the two groups(P＞0.05).The pH values at T0-T5 showed no significant differences between the two groups(all P＞0.05).The OI at T,had no significant difference compared to that at T0 in both groups(P＞0.05);OI at T2-T5 in both groups was significantly lower than that at T0(P＜0.05);OI in the observation group at T2-T5 was significantly higher than that in the control group(P＜0.05).Qs/Qt at T2-T5 was significantly higher than that at T0 and T1 in both groups(all P＜0.05);Qs/Qt in the observation group at T2-T5 was significantly lower than that in the control group(P＜0.05).At T3 and T5,serum SP-A and IL-6 levels in both groups were significantly higher than those at T0(P＜0.05);serum SP-A and IL-6 levels in the observation group at T3 and T5 were significantly lower than those in the control group(P＜0.05).At T3 and T5,serum IL-10 level in the control group were significantly lower than that at T0,while serum IL-10 level in the observation group were significantly higher than that at T0(P＜0.05).Serum IL-10 level in the observation group at T3 and T5 were higher than that in the control group(P＜0.05).At T3 and T5,serum MDA level in the control group was significantly higher than that at T0(P＜0.05);serum MDA level in the observation group showed no significant difference compared to that at T0(P＞0.05);serum MDA level in the observation group was significantly lower than that in the control group(P＜0.05).At T3 and T5,serum SOD level in the control group was significantly lower than that at T0,while serum SOD level in the observation group was significantly higher than that at T0(P＜0.05);serum SOD level in the observation group was significantly higher than that in the control group(P＜0.05).Four patients in the observation group experienced symptoms of unilateral recurrent laryngeal nerve block,and one patient experienced brachial plexus nerve block,but all improved within 24 hours after surgery.No other adverse reactions were observed during follow-up.Within 72 hours postoperatively,one patient in the control group experienced hypoxemia.Conclusion Preoperative ultrasound-guided SGB has lung-protective effects on patients undergoing OLV in thoracoscopic surgery,which significantly improves OI,reduces intrapulmonary shunts,and inhibits inflammatory response and oxidative stress.

Magnesium-doped calcium silicate(CS)bioceramic scaffolds have unique advantages in mandibular defect repair;however,they lack antibacterial properties to cope with the complex oral microbiome.Herein,for the first time,the CS scaffold was functionally modified with a novel copper-containing polydopamine(PDA(Cu2+))rapid deposition method,to construct internally modified(*P),externally modified(@PDA),and dually modified(*P@PDA)scaffolds.The morphology,degradation behavior,and mechanical properties of the obtained scaffolds were evaluated in vitro.The results showed that the CS*P@PDA had a unique micro-/nano-structural surface and appreciable mechanical resistance.During the prolonged immersion stage,the release of copper ions from the CS*P@PDA scaffolds was rapid in the early stage and exhibited long-term sustained release.The in vitro evaluation revealed that the release behavior of copper ions ascribed an excellent antibacterial effect to the CS*P@PDA,while the scaffolds retained good cytocompatibility with improved osteogenesis and angiogenesis effects.Finally,the PDA(Cu2+)-modified scaffolds showed effective early bone regeneration in a critical-size rabbit mandibular defect model.Overall,it was indicated that considerable antibacterial property along with the enhancement of alveolar bone regeneration can be imparted to the scaffold by the two-step PDA(Cu2+)modification,and the convenience and wide applicability of this technique make it a promising strategy to avoid bacterial infections on implants.

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.

Purpose To investigate the clinical pathology of SMARCB1/INI1-deficient poorly differentiated chordoma.Methods Ten patients with poorly differentiated chordoma were collected.The expression of CK,vimentin,INI1,and Brachyu-ry was detected using EnVision immunohistochemistry.Clinical characteristics,histopathological features,as well as related prognosis were analyzed and the literature was reviewed.Results Among the 10 cases,including 5 males and 5 females,the mean age of onset was 4 years.10 cases were located in the cliv-us and had bone invasion,3 involved the cervical spine(18.2％).In morphology,tumor cells showed sheet or nest mass growth,with epithelioid tumor cells.The nucleus was round or oval,with obvious atypia and visible nucleoli.Mitotic figures were active.Lymphocytic infiltration was noted in the stroma.Tumor cells in 10 cases were positive for CK,Vimen-tin,EMA and Brachyury with loss of SMARCB1/INI1 expres-sion.Ten patients were followed-up postoperatively.5 patients had tumor recurrence(median progression-free survival was 4 months)and 7 died(median overall survival was 5 months).Conclusion SMARCB1/INI1-deficient poorly-differentiated chordoma is a relatively rare bone tumor with poor prognosis and challenging diagnosis.Understanding the clinical pathological characteristics of this tumor has great significance for diagnosis and treatment.

ObjectiveTo investigate the distribution and trend of rehabilitation personnel of China Disabled Persons' Federation (CDPF) system and the people with disabilities (PWDs) using geographical gravity model. MethodsBased on ArcGIS and statistical data, the distribution of geographical center of gravity of the rehabilitation personnel of the CDPF system from 2011 to 2021 was analyzed. According to the economic development, the areas were divided into three regions, and the eastern region included eleven provincial units, the central region includes eight provincial units, and the western region included twelve provincial units. ResultsCompared with 2011, rehabilitation staffs per thousand PWDs increased at 107.5% in 2021, 81.1%, 114.2% and 174.1% for the eastern, central, and western regions, respectively; professional staffs increased at 190.5%, 148.8%, 284.6% and 280.6% for the eastern, central, and western regions, respectively; managerial staff increased at 80.0%, 46.8%, 554.3% and 128.1% for the eastern, central, and western regions, respectively. Compared with 2011, the geographical center of gravity of the rehabilitation personnel moved about 330.9 km in 2021, while the geographical center of gravity of the PWDs moved about 169.64 km. ConclusionThe rehabilitation personnel in the CDPF system is the most in the eastern region and least in the western region. The tracks of the geographical center of gravity of the three kind of rehabilitation personnel in the CDPF system are relatively consistent. The rehabilitation personnel in the eastern region are more concentrated than those in the western region, and the density of the PWDs is more westward than that of the rehabilitation personnel, and coordination is not a perfect match yet. It is necessary to strengthen the rehabilitation personnel allocation in the western region, to balance distribution of human resources for rehabilitation of PWDs among regions.

Gypenosides, structurally analogous to ginsenosides and derived from a sustainable source, are recognized as the principal active compounds found in Gynostemma pentaphyllum, a Chinese medicinal plant used in the treatment of the metabolic syndrome. By bioactive tracking isolation of the plants collected from different regions across China, we obtained four new gypenosides (1-4), together with nine known gypenosides (5-13), from the methanol extract of the plant. The structures of new gypenosides were elucidated by one-dimensional (1D) and two-dimensional (2D) nuclear magnetic resonance (NMR) spectra, complemented by chemical degradation experiments. Through comprehensive evaluation involving COL1A1 promoter assays and PP2Cα activity assays, we established a definitive structure-activity relationship for these dammarane-type triterpenoids, affirming the indispensability of the C-3 saccharide chain and C-17 lactone ring in effectively impeding extracellular matrix (ECM) deposition within hepatic stellate cells. Further in vivo study on the CCl₄-induced liver damage mouse model corroborated that compound 5 significantly ameliorated the process of hepatic fibrosis by oral administration. These results underscore the potential of dammarane-type triterpenoids as prospective anti-fibrotic leads and highlight their prevalence as key molecular frameworks in the therapeutic intervention of chronic hepatic disorders.

Objective:To understand the results of serum protein electrophoresis in patients with acute brucellosis, and to provide objective indicators for clinical diagnosis and treatment of acute brucellosis patients.Methods:Thirty acute brucellosis patients diagnosed by the Center for Disease Prevention and Control of Donghe District, Baotou City from January to June 2021 were selected as the case group, and 30 local healthy persons who took physical examination during the same period were selected as the control group. Blood samples were collected from the two groups of people, serum was separated and serum protein electrophoresis was performed. Independent sample t-tests were used to compare total protein concentrations, protein fractions (albumin, α1-globulin, α2-globulin, β-globulin and γ-globulin) and albumin/globulin (A/G) ratio. Results:The age of patients in the case group was (52.35 ± 6.74) years old, with 25 males and 5 females. The course of the disease ranged from 0.3 to 2.6 months, with an average of 1.78 months. The age of people in the control group was (52.74 ± 5.47) years old, with 25 males and 5 females. There were no statistically significant difference in age and sex distuibution between the two groups ( P > 0.05). The concentrations of total protein and α2-globulin fractions were not significantly different between the two groups ( t = 0.78, 2.04, P > 0.05, respectively). Compared with the control group, the differences in the percentage of albumin, α1-globulin, β-globulin, γ-globulin in total protein and A/G ratio were statistically significant ( t = 4.78, 4.76, 2.89, 2.20, 3.65, P < 0.05). Conclusions:The percentage of serum albumin in total protein and A/G ratio decrease in patients with acute brucellosis, while the percentage of α1-globulin, β-globulin and γ-globulin in total protein increase. The percentage of albumin, α1-globulin, β-globulin, γ-globulin in total protein and A/G ratio can be uesed as objective indicators for clinical treatment of acute brucellosis.
