For middle-aged and elderly patients with conditions such as spinal fractures and degenerative spinal diseases, spinal internal fixation is a core surgical procedure for reconstructing spinal stability, heavily relying on the biomechanical stability provided by pedicle screw systems. Whereas, these patients are often complicated by osteoporosis that can significantly compromise the stability of the bone-pedicle screw interface, leading to a marked increase in pedicle screw loosening and surgical failure rates. The bone cement-augmented pedicle screw technique, which involves injecting bone cement into the vertebral body or screw trajectory to optimize the mechanical properties of the bone-pedicle screw composite, has been proven to significantly enhance fixation strength and effectively prevent screw-related failures, thereby reducing the incidence of internal fixation failure in high-risk populations undergoing spinal fusion. However, the widespread clinical application of this technique has faced challenges such as inaccurate clinical decision-making (indication and contraindication selection), non-standardized operative practices, and insufficient awareness of complication prevention, resulting in considerable variability in clinical outcomes and even severe complications. To address this, Prof. Luo Fei from First Affiliated Hospital of Army Medical University initiated the project and the Chinese Association Orthopaedic Surgeons organized relevant experts to develop the Evidence-based clinical practice guideline for bone cement-augmented pedicle screw technique ( version 2025), based on current evidence. The guidelines put forward 8 recommendations regarding the clinical value, scope of application, and operational standards of the technique, aiming to provide evidence-based medical support and technical standardization for clinical decision-making.

Background: and Purpose The optimal management of patients with acute basilar artery occlusion (BAO) is uncertain. We aimed to evaluate the safety and efficacy of endovascular thrombectomy (EVT) compared to medical management (MM) for acute BAO through a meta-analysis of randomized controlled trials (RCTs). Methods: We performed a systematic review and meta-analysis of RCTs of patients with acute BAO. We analyzed the pooled effect of EVT compared to MM on the primary outcome (modified Rankin Scale [mRS] of 0–3 at 3 months), secondary outcome (mRS 0–2 at 3 months), symptomatic intracranial hemorrhage (sICH), and 3-month mortality rates. For each study, effect sizes were computed as odds ratios (ORs) with random effects and Mantel-Haenszel weighting. Results: Four RCTs met inclusion criteria including 988 patients. There were higher odds of mRS of 0-3 at 90 days in the EVT versus MM group (45.1% vs. 29.1%, OR 1.99, 95% confidence interval [CI] 1.04–3.80; P=0.04). Patients receiving EVT had a higher sICH compared to MM (5.4% vs. 0.8%, OR 7.89, 95% CI 4.10–15.19; P<0.01). Mortality was lower in the EVT group (35.5% vs. 45.1%, OR 0.64, 95% CI 0.42–0.99; P=0.05). In an analysis of two trials with BAO patients and National Institutes of Health Stroke Scale (NIHSS) <10, there was no difference in 90-day outcomes between EVT versus MM. Conclusion In this systematic review and meta-analysis, EVT was associated with favorable outcome and decreased mortality in patients with BAO up to 24 hours from stroke symptoms compared to MM. The treatment effect in BAO patients with NIHSS <10 was less certain. Further studies are of interest to evaluate the efficacy of EVT in basilar occlusion patients with milder symptoms.

Objective To evaluate the method of hemodialysis patients with the diagnosis and treatment of herpes zoster.Methods Diagnosis and treatment of 27 cases of hemodialysis patients with varicella-zoster virus (VZV) infection in patients with clinical data.Results All patients in addition to continuing the line hemodialysis treatment,use the ganciclovir,topical recombinant human interferon α -1b cream,vitamin Bl,Methycobal,antibiotics to prevent bacterial infection,oral medicine,comprehensive treatment of pain.The total effective rate of treatment group is 92.59％.Conclusion VZV was a common disease in hemodialysis patients,easy diagnosis,rational drug treatment is very important,need comprehensive treatment can achieve good results.

Objective To explore effective treatment of uremic hemodialysis patients with chronic helicobacter pylori-negative erosive gastritis.Methods Fourty-eight cases of uremic hemodialysis patients with helicobacter pylori-negative chronic erosive gastritis were diagnosed by detection of helicobacter pylori and endoscopic examination.Fourty-eight patients were randomly divided into two groups,treatment group (24 patients) with oral pantoprazole 40 mg,once a day,combinding with oral Marzulene-S particles,each 0.67 g,three times a day,the control group (24 cases ) only with the dose of pantoprazole treatment.Effect of treatment was compared in these two groups after treatment for 21 days.Results Twenty-one days after treatment,the clinical symptoms of uremic hemodialysis patients with upper gastrointestinal improved in treatment group,and the performance of endoscopic and histopathological has varying degree of improvement.It shows that pantoprazole combined with Marzulene-S treatment group has a significant effect than that single treatment with pantoprazole group.In the treatment group,the total effective rate was 95.83％,however it was 83.33％ in the control group( U =2.716,P ＜ 0.01 ).Repair of mucosal lesions were significantly different between the two groups ( total effective rate 83.33％ vs 45.83％,U =2.349,P ＜ 0.05 ).Conclusion Pantoprazole combined with Marzulene-S therapy has a significant effect on uremic hemodialysis patients with chronic Helicobacter pylori-negative erosive gastritis.

Objective To investigate the relationship between platelet-derived growth factor(PDGF)and granulocyte colony-stimulating factor(G-CSF)and psoriasis vulgaris.Methods Sera were taken from60patients with psoriasis vulgaris and42healthy controls.The serum levels of PDGF and G-CSF were measured by a dual antibody sandwich enzyme-linked immunosorbent assay(ELISA).Clinical severity of psoriasis vul-garis was assessed by psoriasis area and severity index(PASI)score.Results The serum PDGF levels were significantly higher in patients with psoriasis vulgaris than those in normal controls(P

Objective To construct recombinant adenovirus vector containing mouse CD40Ig fusion gene for the study of induction of donor-specific tolerance. Methods CD40Ig fusion gene was constructed by PCR overlapping technique, and was cloned into the shuttle plasmid pAdTtrack-CMV. The linearized shuttle plasmid was co-transfected into the E.coli strain BJ5183 with bone plasmid pAdeasy1, then the recombinant adenovirus plasmid was generated. The adenovirus was packaged and amplified in Cells 293. Results The recombinant virus AdCD40Ig was successfully constructed and its titer was 5?109 efu/ml. Conclusion AdCD40Ig can be used as an agent in experiment to induce donor-specific tolerance.
