Vertebral refracture following percutaneous vertebral augmentation (PVA) is commonly seen in elderly patients with osteoporotic thoracolumbar compression fractures (OTLCF). It can lead to recurrent pain, loss of vertebral height, progression of kyphosis, and even neurological dysfunction, significantly impairing patients′ quality of life. Current diagnosis and treatment face multiple challenges, including high misdiagnosis rate, difficulty in choosing between surgical and non-surgical treatment options, lack of standardized surgical protocols, interference from intralesional bone cement during procedures, inadequate stability of internal fixation in osteoporotic bone, and suboptimal compliance of anti-osteoporotic therapy. Establishing a standardized diagnostic and therapeutic framework is urgently needed. To standardize the management process and improve outcomes for vertebral refractures after PVA in elderly OTLCF patients, Spinal Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field to develop Guideline for the diagnosis and treatment of vertebral refracture after percutaneous vertebral augmentation in elderly patients with osteoporotic thoracolumbar compression fractures ( version 2025), based on current literature and clinical experience, and adhering to principles of scientific rigor and clinical applicability. A total of 11 recommendations were proposed, encompassing diagnosis, treatment, and rehabilitation of vertebral refracture after PVA in elderly patients with OTLCF, aiming to provide a foundation for a standardized management.

OBJECTIVE: To evaluate the effectiveness of Kirschner wire fixation and coracoclavicular ligament reconstruction with suture anchor in the treatment of Cho type ⅡC distal clavicle fractures. METHODS: The data of 17 patients with Cho type ⅡC distal clavicular fractures, who were treated with Kirschner wire fixation and coracoclavicular ligament reconstruction with suture anchor between June 2019 and June 2021, was retrospectively analyzed. There were 11 males and 6 females with an average age of 38.7 years (range, 19-72 years). The fractures were caused by falling in 12 cases and traffic accident in 5 cases. All patients had fresh closed fractures. The interval from injury to operation was 1-5 days (mean, 2.6 days). The preoperative injury severity score (ISS) was 6-27 (mean, 10.2). The operation time, intraoperative blood loss, hospital stay, fracture healing, and postoperative complications were analyzed. The shoulder joint function was evaluated by disabilities of the arm, shoulder, and hand (DASH) score and Constant score at last follow-up. RESULTS: All operations were completed successfully. The operation time was 20-50 minutes (mean, 31.6 minutes). The intraoperative blood loss was 30-100 mL (mean, 50.6 mL). The hospital stay was 4-9 days (mean, 5.3 days). All incisions healed by first intention. All patients were followed up 12-16 months (mean, 13 months). All clavicle fractures healed, and the healing time was 8-15 weeks (mean, 11 weeks). No complications such as fracture displacement or nonunion caused by internal fixation failure occurred. During the follow-up, skin irritation caused by the Kirschner wire withdrawal occurred in 3 cases. The Kirschner wires were removed after fracture healing in 17 patients. At last follow-up, the Constant score of shoulder joint was 90-100 (mean, 98.2). The DASH score was 0-10 (mean, 1.5). CONCLUSION Kirschner wire fixation combined with coracoclavicular ligament reconstruction with suture anchor in the treatment of Cho type ⅡC distal clavicle fractures has less postoperative complications and slight complications. It is convenient to remove the internal fixator. The Kirschner wire does not fix the distal clavicle fracture through the acromion, which has little effect on shoulder joint function and can obtain good effectiveness.

Objective:To explore the effects of electroacupuncture combined with hyperbaric oxygen (HBO) therapy for the improvement of the neural function and cognitive ability in patients with hypertensive cerebral hemorrhage.Methods:A total of 180 patients with hypertensive cerebral hemorrhage admitted in Department of Neurology of the Sinopharm-Gezhouba Central Hospital of China Three Gorges University from the January of 2016 to the June of 2019 were selected and randomly divided into hyperbaric oxygen group (HBO group) ( n=60), electric acupuncture group (EA group) ( n=60), and EA combined HBO treatment group (EA+ HBO group) ( n=60) by random number table method. The clinical curative effect and the improvements of cerebral edema, neural function, and cognitive ability were compared in the three groups before and after treatment. Results:After 2 and 4 courses of the treatment, the absolute cerebral edema volume and relative cerebral edema volume of the patients were gradually decreased, and the absolute volumes in the EA+ HBO group were significantly decreased compared with those in the HBO group and the EA group with statistically significant differences ( P<0.05). After 4 courses of the treatment, the total effective rate of the EA+ HBO group was 91.67%, which was significantly higher than those of the HBO group (81.67%) and the EA group (76.67%) with statistically significant differences ( P<0.05). The serum neuron-specific enolase (NSE) and S100β levels of the three groups were significantly lower than those before the treatments, and the levels in the EA+ HBO group were lower than those in other two groups. The differences were statistically significant ( P<0.05). After treatment, the mini-mental state examination (MMSE) score and Barthel index score of the patients were significantly increased ( P<0.05), and the improvement of MMSE score in the EA+ HBO group was significantly better than those in the HBO group and the EA group with statistically significant differences ( P<0.05). Conclusion:Electroacupuncture combined with HBO can effectively reduce cerebral edema, repair cerebral nerve damage, and improve patients′ cognitive function through electrical stimulation and abatement of ischemia and hypoxia.

Surface molecularly imprinted polymers (SMIPs) for selective adsorption of ampicillin sodium were synthesized using surface molecular imprinting technique with silica gel as a support. The physical and morphological characteristics of the polymers were investigated by scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), elemental analysis and nitrogen adsorption–desorption test. The obtained results showed that the SMIPs displayed great adsorption capacity (13.5μg/mg), high recognition ability (the imprinted factor is 3.2) and good binding kinetics for ampicillin sodium. Finally, as solid phase extraction adsorbents, the SMIPs coupled with HPLC method were validated and applied for the enrichment, purification and determination of ampicillin sodium in real milk and blood samples. The averages of spiked accuracy ranged from 92.1%to 107.6%. The relative standard deviations of intra-and inter-day precisions were less than 4.6%. This study provides a new and promising method for enriching, extracting and determining ampicillin sodium in complex biological samples.

This research was to study the regulation of intravenous administration of human umbilical cord blood mesenchymal stem cells (HUCBMSCs) on secretion of neural specific protein in rats after traumatic brain injury (TBI), and to explore its mechanisms promoting the recovery of neurological function. The TBI models of rats were established. We then injected HUCBMSCs, labelled by Brdu (5-bromo-2-deoxyuridine), into the TBI rats via the tail vein using modified Feeney free-falling method. The levels of neural biochemical indicators (serum S100β protein, NSE, LDH, CK) of rats were detected in shamed group, injury group and HUCBMSCs-transplanted group. And the morphological changes of brain tissue of rats in the three groups were observed by using HE staining under light microscope. During the whole experiment no immunosuppressant was used for the four groups. From the research, transplant-related death of the rats was not found in transplantation group. In the injury group, rises were found in contents of serum S100β protein, NSE, LDH, CK in the early stage after the rats were injured, which were much higher than those in shamed group at correspondent time point (P < 0.01). In HUCBMSCs-transplanted group, although these biochemistry indexes were found rising for a short period in the early stage, along with the time, these indexes were obviously lower than in those injury group (P < 0.05). Under light microscopy pathological changes of rats in HUCBMSCs-transplanted group were much slighter than those in injury group. It was well concluded that in the situation of no immuno-suppressants, the intravenous-injected HUCBMSCs could reduce the secretion of serum S100β protein, NSE, LDH, CK, promote the repair of tissue injury effectively, and promote the functional recovery of neurons.
