Nonunion of osteoporotic vertebral fractures (OVF), predominantly affecting the elderly, can lead to intractable pain, vertebral collapse, progressive kyphotic deformity, and neurological impairment, significantly compromising patients′ quality of life. There exists considerable debate on diagnosis and management of OVF, encompassing key issues such as clinical diagnosis and staging criteria for nonunion, surgical indications and procedure selection, and postoperative rehabilitation planning. Currently, there lacks standardized clinical guideline and expert consensus on the diagnosis and management of OVF nonunion in China. To address this gap, Minimally Invasive Surgery Group of Chinese Orthopedic Association, Osteoporosis Committee of Chinese Association of Orthopedic Surgeons, Prevention and Rehabilitation Committee for Osteoporosis of Chinese Association of Rehabilitation Medicine and Minimally Invasive Orthopedic Surgery Branch of China Association for Geriatric Care jointly organized domestic experts in spinal surgery, endocrinology, and rehabilitation to formulate the Clinical guideline for the diagnosis and treatment for nonunion of osteoporotic vertebral fractures ( version 2025), based on existing literature and clinical experience and adhering to principles of scientific rigor and practicality. The guideline provided 13 evidence-based recommendations encompassing diagnosis and treatment of OVF nonunion, aiming to standardize its clinical management.

OBJECTIVES: To compare the anti-inflammatory, antibacterial and analgesic effects of Yinqiao Powder (YQS) formulated granules and decoction. METHODS: We first evaluated the anti-inflammatory effects of the two dosage forms of YQS in a LPS-induced RAW 264.7 cell model using RT-qPCR and Western blotting. We further constructed zebrafish models of inflammation by copper sulfate exposure, caudal fin transection, or LPS and Poly (I:C) microinjection, and evaluated anti-inflammatory effects of YQS granules and decoction by examining neutrophil aggregation and HE staining findings. In a mouse model of acute lung injury (ALI) induced by intratracheal LPS instillation, the effects of YQS gavage at 10, 15, and 20 g/kg on lung pathologies were evaluated by calculating lung wet-dry weight ratio and using HE staining, ELISA and Western blotting. The microbroth dilution method was used to evaluate the antibacterial effect of YQS. Mouse pain models established by hot plate and intraperitoneal injection of glacial acetic acid were used to evaluate the analgesic effects of YQS at 10, 15, and 20 g/kg. RESULTS: Both YQS granules and decoction significantly reduced TNF-α, IL-6, and IL-1β expressions and p-STAT3 (Tyr 705) phosphorylation level in LPS-induced RAW 264.7 cells, and obviously inhibited neutrophil aggregation in the zebrafish models. In ALI mice, YQS granules and decoction effectively ameliorated lung injury, lowered lung wet-dry weight ratio, and reduced p-STAT3 (Tyr 705) expression and TNF-α and IL-6 levels. YQS produced obvious antibacterial effect at the doses of 15.63 and 31.25 mg/mL, and significantly reduced body torsion and increased pain threshold in the mouse pain models. CONCLUSIONS The two dosage forms of TQS have similar anti-inflammatory, antibacterial and analgesic effects with only differences in their inhibitory effect on TNF-α, IL-6 and IL-1β mRNA expressions in LPS-induced RAW 264.7 cells.

Acute lung injury (ALI), as a common clinical emergency, is pulmonary edema and diffuse lung infiltration caused by inflammation. The lack of non-invasive alert strategy, resulting in failure to carry out preventive treatment, means high mortality and poor prognosis. Stimulator of interferon genes (STING) is a key molecular biomarker of innate immunity in response to inflammation, but there is still a lack of STING-targeted strategy. In this study, a novel STING-targeted PET tracer, [¹⁸F]FBTA, was labeled with high radiochemical yield (79.7 ± 4.3%) and molar activity (32.5 ± 2.9 GBq/μmol). We confirmed that [¹⁸F]FBTA has a strong STING binding affinity (K_d = 26.86 ± 6.79 nmol/L) and can be used for PET imaging in ALI mice to alert early lung inflammation and to assess the efficacy of drug therapy. Our STING-targeted strategy also reveals that [¹⁸F]FBTA can trace ALI before reaching the computed tomography (CT) diagnostic criteria, and demonstrates its better specificity and distribution than [¹⁸F]fluorodeoxyglucose ([¹⁸F]FDG).

Objective:To evaluate the prevalence and related risk factors of new onset diabetes after chronic pancreatitis by meta-analysis.Methods:Chronic pancreatitis, diabetes, post pancreatitis diabetes, type 2 diabetes, type 3c diabetes, endocrine dysfunction, chronic pancreatitis, diabetes mellitus, post pancreatitis diabetes mellitus, endocrine efficiency, risk factors were used as keywords, and the network database such as the CNKI database, Wanfang, Weipu, Chinese Medical Journal Full Text, PubMed, Embase, Cochrane Library, Web of Science, and so on from the database establishment to January 2023 were searched. The prospective and retrospective cohort studies on new diabetes after chronic pancreatitis published were searched and retrieved, and the papers were screened and the quality were evaluated according to preset inclusion and exclusion criteria; and the important data were extracted. Review Manager 5.4 was used for meta-analysis.Results:22 papers were finally included, including 13 785 patients with chronic pancreatitis, of which 4 233 were patients with new onset diabetes. Meta-analysis showed that the incidence of new diabetes after chronic pancreatitis was 29% ( RD=0.29, 95% CI 26%-32%, P<0.0001), which increased and tended to be stable along with the disease course. Alcohol drinking, smoking, alcoholic chronic pancreatitis, pancreatic calcification, biliary stricture, male, conservative treatment, pancreatic cyst and older onset age were considered as risk factors for new diabetes after chronic pancreatitis, and endoscopic treatment was considered as protective factors. Conclusions:The incidence of new diabetes after the diagnosis of chronic pancreatitis is relatively high. Clinically, we can identify high-risk groups exposed to risk factors, and early intervention can reduce the incidence rate of new diabetes after chronic pancreatitis and improve the prognosis of patients.

Objective To evaluate the effectiveness and predictive value of high-resolution manometry(HRM) for POEM in treating achalasia. Methods A total of 84 achalasia patients categorized into subtypes by HRM, who also underwent POEM, were enrolled in our study. Eckardt score, Barium esophagogram and HRM were performed before, 6 months and 1 year after POEM. Results POEM was successfully performed in all 84 patients. No perforation occurred in any patient. The Eckardt scores and esophageal diameter after POEM significantly reduced compared with those before(P<0. 05). The 4s-IRP decreased from 33. 4±9. 0 mmHg (1 mmHg =0. 133 kPa) to 14. 6±3. 8 mmHg six months after POEM (P<0. 05) and to 16. 4±3. 9 mmHg one year after POEM (VS preoperate, P<0. 05). The LESP before treatment was 41. 8±15. 4 mmHg, decreasing to 18. 4±7. 1 mmHg six months after POEM (P<0. 05) and 20. 7±7. 6 mmHg one year after POEM (VS preoperate, P <0. 05) . When categorizing patients into 3 subtypes by HRM, 4s-IRP of type II showed the most dramatic decrease six months after POEM(62. 8%), followed by typeⅠ(53. 5%), while type III had the least decrease(41. 8%). The mean decreasing rate of LESP in type III was 42. 3% six months after POEM, followed by typeⅠ(55. 3%) , while type II showed the highest rate(57. 8%). Conclusion POEM is a safe treatment for achalasia and has significant short-term efficacy with Type II responding best to POEM. HRM plays a vital role in typing AC and predicting the effectiveness of POEM and can be useful in selecting an appropriate treatment.

Objective To evaluate the arrival peak time (APT) of contrast medium to abdominal aorta at different dosages with 64-detector CT scanner.Methods Sixty cases with normal cardiac function were divided randomly into three groups(group A,B,C).The injection rate of group A,B,C was 4.5 ml/s,3.5 ml/s,4.5 ml/s respectively.A small test bolus and the enhancement dosage bolus were at the same injection rate.After the injection of contrast medium was done,20 ml saline chaser was followed in group A and B but group C.20 patients with cardiac dysfunction as group D received the same injection protocol as group A.The concentration of contrast medium was 370 mgI/ml and cine-modal was used in contrast-enhanced scanning.The time-density curve of abdominal aorta at the level of porta hepatic and APT were measured at the different group and the different dosage.Results APT of contrast medium of the small test bolus in group A,B,and C ranged from 19 s to 24 s with mean time(20?2) s,(19?3) s and(22?3) s respectively.In group D,APT ranged from 24 s to 42 s with mean time(28?14) s.APT of enhancement dosage ranged from 20 s to 26 s among group A, B,C with mean(22?3) s,(21?2) s and(24?2) s respectively.In group D,APT ranged from 26 s to 44 s,with mean time(32?14) s.The difference of APT between test bolus and enhancement dosage was 2~7 s among group A,B and C,and was 3~12 s in group D.Conclusion The APT of abdominal aorta at the level of porta hepatis between test bolus and enhancement dosage in the patients with normal cardiac function or with cardiac dysfunction is different.
