Thoracolumbar spine fracture often leads to severe pain, functional impairments, and neurological deficits, for which open reduction and internal fixation can effectively restore the spinal structural stability. Open decompression and reduction with internal fixation can help relieve spinal cord compression and improve spinal function in cases of concomitant cord injury. Although spinal stability can be restored through surgery, patients often face chronic pain and functional impairments postoperatively. A postoperative rehabilitation program is critical in optimizing therapeutic outcomes, reducing complications, and minimizing the risk of secondary injuries. However, current rehabilitation methods, such as physical therapy, functional training, and pain management, are confronted with problems in clinical practice, including significant variation in efficacy, poor patient adherence, and prolonged rehabilitation period. There is an urgent need for a unified rehabilitation strategy to address these problems. To this end, the Spinal Trauma Group of the Orthopedic Physicians Branch of the Chinese Medical Association and the Spine Health Professional Committee of the Chinese Human Health Technology Promotion Association organized experts from relevant fields to formulate Evidence-based guidelines for rehabilitation treatment after internal fixation of thoracolumbar spine fracture in adults ( version 2025) by integrating evidences from clinical researches and advanced rehabilitation concepts at home and abroad. A total number of 14 recommendations concerning the rehabilitation treatment with multimodal analgesia, psychological intervention, deep vein thrombosis prevention, core muscle and extremity exercise, appropriate use of braces, early weight-bearing, device-aided rehabilitation exercise, neuroregulatory therapy, rehabilitation team were put forward, aiming to standardize the post-operative rehabilitation process following internal fixation, promote the functional recovery, and enhance patients′ quality of life.

Acute symptomatic osteoporotic thoracolumbar compression fracture (ASOTLF) can lead to chronic low back pain, kyphosis deformity, pulmonary dysfunction, loss of mobility, and even life-threatening complications. Vertebral augmentation is currently the mainstream treatment method for this condition. In 2019, the Editorial Board of Chinese Journal of Trauma and the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association collaboratively led the development of Clinical guideline for vertebral augmentation for acute symptomatic osteoporotic thoracolumbar compression fractures. Six years later, with advances in clinical diagnosis and treatment techniques as well as accumulating evidence in related fields, the 2019 guideline requires updating. To this end, the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association, the Spinal Health Professional Committee of China Human Health Science and Technology Promotion Association, and the Minimally Invasive Orthopedics Professional Committee of Shaanxi Medical Doctor Association have organized experts in the field to develop the Clinical guideline for vertebral augmentation of acute symptomatic osteoporotic thoracolumbar compression fractures ( version 2025) , based on the latest evidence-based medical researches. This guideline incorporates 3 recommendations retained from the 2019 version with updated strength of evidence, along with 12 new recommendations. It provides recommendations from six aspects of diagnosis, pain management, treatment option selection, prevention of postoperative complications, anti-osteoporosis therapy, and postoperative rehabilitation, aiming to provide a reference for standard treatment of vertebral augmentation for ASOTLF in hospitals at all levels.

Objective:To explore the intervention effect of Jianpifuwei granule(JPFWG)on gastric mucosal injury in rats with precancerous lesions of gastric cancer(PLGC)by regulating the IL-6/JAK/STAT3 signaling pathway and its mechanism.Methods:The PLGC model rats were established by MNNG combined with composite factors,and randomly divided into 6 groups(20 rats/group):the blank group(untreated),model group(treated with normal saline),Weimeisu group(0.05 g/mL Weimeisu),JPFWG low-dose group(JPFWG-L,0.088 g/mL),JPFWG medium-dose group(JPFWG-M,0.176 g/mL)and JPFWG high-dose group(JPFWG-H,0.351 g/mL).After being treated with Weimeisu and different doses of JPFWG for 12 weeks,the animals were anesthetized and sacrificed,and the gastric tissues were collected.The pathological changes of gastric mucosa were observed by H-E staining,and the expression levels of IL-6-mediated JAK/STAT3 signaling pathway factors(including IL-6,JAK and STAT3)and the mRNA and proteins of their downstream target genes c-Myc and cyclin D1 in gastric mucosal tissues were detected by immunohistochemistry,qPCR and WB.Results:Compared with that in the model group,the gastric mucosal inflammatory cell infiltration was reduced in the Weimeisu group and the low,medium,and high dose groups of JPFWG;pathological condition was improved,most obviously in the high dose group of JPFWG;The protein expressions of IL-6,JAK1 and STAT3 decreased significantly(P<0.05 or P<0.01).The expressions of mRNA and proteins of c-Myc and cyclin D1 in the gastric mucosal tissues of the rats in the Weimeisu group and JPFWG-H group decreased significantly(P<0.05 or P<0.01).Conclusion:JPFWG can improve the histopathological changes of gastric mucosa in rats with PLGC,and its mechanism may be down-regulating the expressions of c-Myc and cyclin D1 through regulating IL-6/JAK/STAT3 signal pathway,thus blocking inflammation-cancer transformation process.

Objective:To investigate the role of TcpC, a virulence factor of uropathogenic Escherichia coli (UPEC), in immune evasion, and analyze its related pathogenic mechanism. Methods:C57BL/6 mice were injected with 10 9 colony-forming unit of wild-type (CFT073 wt) or tcpc gene-knockout (CFT073 Δ tcpc) UPEC CFT073 strains from urethra into bladder to construct a mouse model of pyelonephritis. These mice were sacrificed 5 d after infection and their kidneys were taken to observe the gross pathological changes. Hematoxylin-eosin staining was used to observe histopathological changes in kidney tissues and immunohistochemistry was performed to locate TcpC in kidney tissues. The bacterial loads in urine samples of UPEC infected-mice were counted by ten-fold dilution method, and the presence of tcpc gene in the genomic DNA of bacteria from CFT073-infected mouse kidney or urine samples was measured by PCR. The expression of TcpC at mRNA level was detected by qRT-PCR after infecting dendritic cells with CFT073 wt strains. The influences of UPEC infection on the activation of NF-κB signaling pathway and the secretion of proinflammatory factors by dendritic cells were analyzed by Western blot and ELISA, respectively. The viability of UPEC strains in dendritic cells were observed by laser confocal microscope. Results:Compared with the CFT073 Δ tcpc group, the mice in the CFT073 wt group had obvious abscess in the kidneys as well as massive neutrophil infiltration and abundant TcpC in kidney tissues. The bacterial loads in the urine of CFT073 wt-infected mice were significantly higher than those in the urine of CFT073 Δ tcpc mice. PCR results showed that tcpc gene was successfully amplified from mouse kidney and urine samples. Increased expression of TcpC at both mRNA and protein levels was detected in CFT073 wt-infected dendritic cells. CFT073 wt infection inhibited the phosphorylation of NF-κB p50 and the production of proinflammatory factors in dendritic cells. TcpC promoted the survival of CFT073 wt in dendritic cells. Conclusions:TcpC expression increases significantly during CFT073 wt infection or in mice with CFT073 wt-induced pyelonephritis. It promotes the survival of CFT073 wt in dendritic cells by inhibiting the activation of NF-κB signaling pathway and reducing the secretion of pro-inflammatory cytokines. TcpC is involved in the pathogenesis of UPEC and immune evasion.

Objective:To investigate the efficacy and prognostic survival of pembrolizumab combined with apatinib and chemotherapy in the treatment of human epidermal growth factor receptor-2 (HER2)-negative advanced gastric cancer.Methods:Patients with HER2-negative advanced gastric cancer were selected from December 2019 to December 2022 as the study subjects. Forty-five patients who received chemotherapy therapy (fluorouracil+cisplatin) were randomly collected and included in control group, and 52 patients who were treated with pembrolizumab combined with apatinib were randomly selected and enrolled as observation group. The difference in short-term efficacy was compared. The levels of serum tumor markers and immune function (CD3 +, CD4 +, CD8 +, CD4 +/CD8 +) were recorded. The long-term efficacy and adverse reactions of patients were compared. Measurement data conforming to the normal distribution were expressed as xˉ± s, and the mean comparison between groups was performed by independent sample t test. Chi-square test was used to compare the rate or composition ratio among enumeration data. P<0.05 was considered statistically significant. Results:At 6 months after treatment, the disease control rate in observation group was significantly higher than that in control group (78.85% (41/52) vs 57.78% (26/45)) ( χ2=5.01, P=0.025), but there was no statistical significance in objective response rate between groups (36.54% (19/52) vs 24.45% (11/45)) ( χ2=1.65, P=0.199). The levels of pepsinogen I, tissue polypeptide specific antigen, carcinoembryonic antigen, carbohydrate antigen 199 and CD8 + in both groups were reduced after treatment, and the levels were lower in observation group than those in control group ( t=6.06, 6.78, 4.68, 11.21, 3.45, all P<0.001). The levels of CD3 +, CD4 + and CD4 +/CD8 + were enhanced significantly in the two groups, and the observation group had higher levels after treatment ( t values were 2.10, 3.74, and 5.19; P values were 0.028, <0.001, and <0.001). After 1 year of follow-up, the survival rate in observation group with 59.62% (31/52) was significantly higher than 37.78% (17/45) in control group ( χ2=4.60, P=0.032). The progression-free survival time ((10.22±1.62) months vs (8.13±1.57) months, t=6.43, P<0.001) and overall survival time ((11.62±1.84) months vs (9.73±1.71) months, t=5.21, P<0.001) in observation group were significantly longer compared to control group. There were no statistical differences in the incidence rates of bone marrow suppression ( χ2=1.92, P=0.165), hand-foot syndrome ( χ2=3.47, P=0.062), gastrointestinal reaction ( χ2=0.32, P=0.574), hypertension ( χ2=0.94, P=0.333) and proteinuria ( χ2=2.39, P=0.122) between the two groups. Conclusion:Compared with chemotherapy, pembrolizumab combined with apatinib shows good short-term efficacy and long-term efficacy in patients with HER2-negative advanced gastric cancer.

Objective:To find the preferences of nursing staff when they provide " Internet + nursing service" for elderly patients.Methods:By means of the discrete choice experiment, a questionnaire was designed to investigate the preferences of nursing staff when they provide " Internet + nursing services" for elderly patients. In-service nursing staff from 8 medical and health institutions in Ningbo city and Wenzhou city were selected by random sampling, for an online questionnaire survey conducted from May to June 2022. The preferences of nursing staff on their service income, service content, service distance, service continuity and residence status of elderly patients when providing " Internet + nursing service" were analyzed by mixed logit regression.Results:A total of 420 valid questionnaires were collected. Compared to 50 yuan/order, nursing staff preferred to a price of 150 yuan/order ( β= 1.22, P<0.001) nursing services; Compared to specialized nursing services, nursing staff preferred to the routine care ( β= 0.86, P<0.001) and health promotion ( β= 0.86, P<0.05) service; Compared to<5 km, nursing staff were unwilling to provide nursing services for elderly patients at distances of 5-10 km and 11-15 km ( β=-0.66, P<0.05; β=-0.95, P<0.001) ; Compared to 1-2 visits per month, nursing staff preferred not to provide continuing care services ( β=-0.70, P<0.05); Compared to homestay with the patient family, nursing staff preferred to provide nursing services for elderly patients residing in nursing homes ( β= 1.21, P<0.001) . Conclusions:Considering the preference of nursing staff tend to provide " Internet + nursing service" for the elderly patients with services featuring appropriate price, non-specialist care, close distance, low continuity (moderate intensity used as the reference) and security assurance for practice.
