Objective:To investigate the safety and utility of using polyester spacers in conventional pancreatico-enteric anastomosis in pancreaticoduodenectomy to achieve prevention of postoperative pancreatic fistula.Methods:The clinical data of 82 patients with pancreaticoduodenectomy completed by the same physician in Anyang People's Hospital from August 2018 to August 2023 were retrospectively analyzed, including 52 males and 30 females, aged (62.21±9.75) years. They were divided into two groups, test group ( n=40) and control group ( n=42) according to whether polyester spacers were used in pancreatico-intestinal anastomosis, the perioperative data of the two groups were compared, and Logistic analysis was used to analyze the risk factors affecting postoperative pancreatic fistula. Results:There was no statistically significant difference between the two groups in terms of biliary fistula, intestinal fistula, abdominal infection, abdominal bleeding, and postoperative mortality rate (all P>0.05). The incidence of postoperative pancreatic fistula in the test group was 20.0% (8/40) which was lower than that in the control group 45.2% (19/42), and the difference was statistically significant ( P=0.015). Soft pancreas texture ( OR=16.595, 95% CI: 1.891~145.657) was an independent risk factor for postoperative pancreatic fistula, while improved pancreatic enterostomy with polyester spacers ( OR=0.332, 95% CI: 0.114~0.969) could reduce the risk of postoperative pancreatic fistula. Conclusion:Use of polyester spacers to reinforce the pancreatico-enteric anastomosis during pancreaticoduodenectomy reduces the incidence of postoperative pancreatic fistulae with good safety and practicality.

The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.

Objective:To explore the molecular mechanism of dexmedetomidine(Dex)protecting ischemia/reperfusion(I/R)myocardium.Methods:Wild type mice were grouped into control(Control)group,sham operation(Sham)group,WT I/R group,WT Dex group,and Dectin-1 knock out mice were grouped into KO I/R group and KO Dex group in the in vivo study(n=6).TTC stain-ing was used to determine the myocardial infarction area(%)of the above six groups of mice.HE staining and pathological analyze was used to determine the myocardial injury.Serum TNF-α,IL-6 and IL-10 levels in mice were detected by ELISA.Flow cytometry(FCM)was used to count and sort of infiltrating M2 macrophages and neutrophils in myocardium.qPCR assay was used to determine the Dectin-1 mRNA expression in the above sorted cells.Results:TTC results showed that there was no myocardial infarction in the mice of Control group and Sham group.Compared with the WT I/R group,the infarct volume was significantly lower in WT Dex group,KO I/R group and KO Dex group(P<0.05).Compared with the KO I/R group,the infarct volume was reduced in KO Dex group(P<0.05).The results of HE staining showed that the myocardial fibers of the WT I/R group of mice were disorderly arranged,with a large number of broken myocardial fibers,while the myocardial fibers of the WT Dex group,KO I/R group and KO Dex group of mice had a little breakage,the structural damage was not significant,and the myocardial arrangement was relatively neat.The degree of myocardi-al injury of mice in KO Dex group were less than that in KO I/R group mice.ELISA results showed that compared with Sham group,the serum TNF-α and IL-6 levels of the mice in WT I/R group were significantly increased,and the IL-10 level was significantly de-creased.Compared with WT I/R group,serum TNF-α and IL-6 levels of the mice in WT Dex group and KO I/R group were significant-ly decreased,and IL-10 level was significantly increased.Compared with KO I/R group,the serum TNF-α and IL-6 levels of the mice in KO Dex group were significantly decreased,and the IL-10 level was significantly increased(P<0.05).FCM cell counting results showed that compared with Sham group,a large number of M2 macrophages and neutrophils were infiltrated in the myocardium of WT I/R group of mice(P<0.05).Compared with WT I/R group,the M2 macrophages and neutrophils infiltrated in the myocardium were significantly decreased in WT Dex group,KO I/R group and KO Dex group of mice(P<0.05).While there was no significant differ-ence between the KO I/R group and the KO Dex group mice(P>0.05).qPCR results showed that compared with Sham group,the ex-pression level of Dectin-1 mRNA in the myocardial infiltrated M2 macrophages and neutrophils were significantly up-regulated in WT I/R group of mice(P<0.05).While compared with WT I/R group,the expression level of Dectin-1 mRNA in Dex group of mice was sig-nificantly lower(P<0.05).Mice in KO I/R group and KO Dex group did not express Dectin-1.Conclusion:The protective mecha-nisms of Dex preconditioning on I/R injured myocardium involves reducing the infiltrating number of M2 macrophages and neutrophils in myocardium after I/R injury,which may be achieved by inhibiting the expression of Dectin-1.

Osteoporotic thoracolumbar fracture in the elderly will seriously reduce their quality of life and life expectancy. For osteoporotic thoracolumbar fracture in the elderly, spinal reconstruction is necessary, which should comprehensively consider factors such as the physical condition, fracture type, clinical characteristics and osteoporosis degree. While there lacks relevant clinical norms or guidelines on selection of spinal reconstruction strategies. In order to standardize the concept of spinal reconstruction for osteoporotic thoracolumbar fracture in the elderly, based on the principles of scientificity, practicality and progressiveness, the authors formulated the Clinical guideline for spinal reconstruction of osteoporotic thoracolumbar fracture in elderly patients ( version 2022), in which suggestions based on evidence of evidence-based medicine were put forward upon 10 important issues related to the fracture classification, non-operative treatment strategies and surgical treatment strategies in spinal reconstruction after osteoporosis thoracolumbar fracture in the elderly, hoping to provide a reference for clinical treatment.

Objective To explore the incidence of pain flare (PF) in spine metastasis stereotactic body radiotherapy (SBRT) or hypofractionated radiotherapy (HF) and the prophylactical effect of dexamethasone. Methods Sixty-five patients were treated with spine metastasis SBRT and randomly divided into control group (SBRT or HF, n=32) and treatment group (SBRT or HF and 4.5 mg dexamethasone, n=33). The brief pain inventory (BPI) was used to score the pain before, during and after treatment. PF was recorded and compared between two groups. Results The incidence of PF was 24.6% in all patients (control group: 37.5%, treatment group: 12.1%, P=0.018). PF in both group occurred in d1-2, accounting for 62.5% in all PF (control group: 66.7%, treatment group: 50%, P=0.551). The incidences of PF in control group were 66.7% and 33.3% for three and ten fractions scheme, respectively (P=0.001). However, the incidences of PF in treatment group were 50% and 50% for three and ten fractions scheme, respectively (P=0.643). Conclusion Oral dexamethasone has an excellent efficacy in prevention and treatment of PF in spine metastasis SBRT or HF, with significantly decreased incidence of PF. A phase Ⅲ clinical trial is required to finalize the optimal dose and schedule.

Objective: To observe the pharmacodynamic effect of Xiaobanxia Decoction (XBXD) and categorized formula on cisplatin-induced delayed chemotherapeutic vomiting in rats, and to explore its prevention and treatment mechanism. Methods: Sixty Wistar rats were randomly divided into blank group, model group, ondansetron group, XBXD group, Ginger Pinellia Decoction group and Pinellia and Dried Ginger Powder group, with 10 rats in each group. The ondansetron group was given 2.6 mg/(kg•d) ondansetron, the XBXD group was given XBXD 22 g/(kg•d), the Ginger Pinellia Decoction group was given 31.5 ml/(kg•d) Ginger Pinellia Decoction, and Pinellia and Dried Ginger Powder group was given 0.63 g/(kg•d) Dried Ginger Powder. The blank group and the model group were intragastrically administered with normal saline. All the treattmens were last for three days and twice per day. After the first administration, except the blank group, the rats in all groups were intraperitoneally injected with 6 mg/kg cisplatin to establish chemotherapy-induced vomiting model. The kaolin intake of the chemotherapical rats were weighed every 24 h, and the ileum and medulla 5-HT, 5-HIAA, TPH and MAOA levels were detected by ELISA. Results: Compared with the model group, the kaolin intake of the chemotherapy rats in each treatment group significantly decreased (P<0.05). The levels of ileum 5-HT (308.04 ± 29.90 ng/L, 355.97 ± 19.16 ng/L, 389.97 ± 24.86 ng/L vs. 498.95 ± 13.92 ng/L) and medulla 5-HT (375.32 ± 19.33 ng/L, 395.18 ± 16.12 ng/L, 406.68 ± 12.09 ng/L vs. 478.52 ± 13.88 ng/L) in the XBXD group, Ginger Pinellia Decoction group and Pinellia and Dried Ginger Powder significantly decreased (P<0.05). The levels of ileum TPH (35.14 ± 2.68 ng/L vs. 47.31 ± 0.83 ng/L) in the XBXD group significantly decreased (P<0.05). The levels of medulla TPH (33.68 ± 2.79 ng/L, 38.19 ± 1.74 ng/L vs. 43.68 ± 1.53 ng/L) in the Ginger Pinellia Decoction group and Pinellia and Dried Ginger Powder significantly decreased (P<0.05). The levels of MAOA, 5-HIAA in the ileum and medulla of the XBXD group, Ginger Pinellia Decoction group and Pinellia and Dried Ginger Powder significantly decreased (P<0.05). Conclusions XBXD and categorized formula can effectively prevent and treat delayed chemotherapy-induced vomiting in rats, and its mechanism may be related to decrease the TPH level and inhibiting 5-HT synthesis.

OBJECTIVE: To evaluate the efficacy of rapmycin for treatment of experimental autoimmune encephalomyelitis (EAE) in mice and explore the underlying mechanism. METHODS: An EAE model was established in C57BL/6 mice. After immunization, the mice were divided into model group and rapamycin groups treated daily with low-dose (0.3 mg/kg) or high-dose (1 mg/kg) rapamycin. The clinical scores of the mice were observed using Knoz score, the infiltration of IL-17 cells in the central nervous system (CNS) was determined using immunohistochemistry; the differentiation of peripheral Treg cells was analyzed using flow cytometry, and the changes in the levels of cytokines were detected with ELISA; the changes in the expressions of p-Smad2 and p- smad3 were investigated using Western blotting. RESULTS: High-dose rapamycin significantly improved the neurological deficits scores of EAE mice. In high-dose rapamycin group, the scores in the onset stage, peak stage and remission stage were 0.14±0.38, 0.43±1.13 and 0.14±0.37, respectively, as compared with 1.14±0.69, 2.14±1.06 and 2.2±0.75 in the model group. The infiltration of inflammatory IL-17 cells was significantly lower in high-dose rapamycin group than in the model group (43±1.83 153.5±7.02). High-dose rapamycin obviously inhibited the production of IL-12, IFN-γ, IL-17 and IL-23 and induced the anti-inflammatory cytokines IL-10 and TGF-β. The percentage of Treg in CD4+ T cells was significantly higher in high- dose rapamycin group than in the model group (10.17 ± 0.68 3.52 ± 0.32). In the experiment, combined treatments of the lymphocytes isolated from the mice with rapamycin and TGF-β induced a significant increase in the number of Treg cells (13.66±1.89) compared with the treatment with rapamycin (6.23±0.80) or TGF-β (4.87±0.85) alone. Rapamycin also obviously up-regulated the expression of p-Smad2 and p-Smad3 in the lymphocytes. CONCLUSIONS Rapamycin can promote the differentiation of Treg cells by up-regulating the expression of p-Smad2 and p-smad3 to improve neurological deficits in mice with EAE.

To investigate whether ischemic postconditioning (IPTC) can promote the recovery of left ventricular impaired regional or global longitudinal systolic function.
 Methods: The trial was divided into a percutaneous coronary intervention (PCI) group, an PCI+IPTC group and a control group. Thirty-two patients with anterior acute anterior wall ST-segment elevation myocardial infarction (STEMI) underwent the first emergency PCI in the PCI group, 28 patients with anterior acute STEMI underwent the combination of PCI and IPTC in the PCI+IPTC group, while 30 patients underwent coronary angiography in the control group. Two-dimensional dynamic echocardiography was collected before operation, 0.5 h, 1 day, 3 days, 1 week, 1 month and 6 months after operation, respectively. The longitudinal strain parameters at different time points were analyzed and compared in the 3 groups.
 Results: The regional longitudinal strain of infracted segments in the PCI+IPTC group after the operation within 1 week was higher than that in the PCI group (P<0.05). The left ventricular global longitudinal strain in the PCI+IPTC group seemed to be higher than that in PCI group after the operation within 1 week, but there was not statistically difference (P>0.05). There was no significant difference in the long-term regional and global longitudinal strains of left ventricle between the PCI+IPTC group and the PCI group (both P>0.05).
 Conclusion: The IPTC can improve the short-term longitudinal systolic function of the reperfused myocardium in patients with acute anterior wall STEMI after PCI.
