OBJECTIVE: To explore the clinical significance of preoperative neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and C-reactive protein (CRP) to albumin (ALB) ratio in spinal surgery patients with postoperative incision infection. METHODS: A total of 373 patients who underwent spinal surgery were collected and devided into two groups according to the postoperative incision infection situation. Among them, 65 cases in the incision infection group included 34 males and 31 females with a mean age of (56.01±9.78) years old;308 cases in the non incision infection group included 157 males and 151 females with a mean age of (55.54±10.19) years old. Blood cell analyzer was applied to detect neutrophils, lymphocytes, and platelets, and calculate NLR and PLR;immunoturbidimetry was applied to measure serum CRP and ALB levels and calculate CRP/ALB ratio;receiver operating characteristic (ROC) curve was applied to analyze the predictive value of preoperative NLR, PLR, and CRP/ALB ratio for postoperative spinal incision infection;Logistic multivariate regression was applied to analyze the influencing factors of incision infection after spinal surgery. RESULTS: The NLR(4.92±1.13), PLR (119.32±22.74), CRP/ALB ratio (10.19±2.51), operation time (3.02±0.64) h, history of diabetes 38.46%(25/65), and the proportion of patients with implant 32.31%(21/65) in the incision infection group were higher than those in the non incision infection group 3.72±0.81, 90.58±20.16, 7.23±2.21, (2.26±0.51) h, 16.88%(53/308), 11.69%(36/308), there were statistical differences(P<0.05). The AUC of preoperative NLR, PLR, and CRP/ALB ratio alone and in combination for predicting postoperative incision infection after spinal surgery was 0.786, 0.806, 0.839, and 0.926, respectively. Preoperative NLR, PLR, and CRP/ALB ratio were independent risk factors for postoperative incision infection in spinal surgery(P<0.05). CONCLUSION The determination of preoperative NLR, PLR, and CRP/ALB ratio is beneficial for early prediction of postoperative spinal incision infection, and the combined detection of the three can further improve the accuracy of the prediction results.

Hypercholesterolemia is a significant risk factor for the development of atherosclerosis. 2',3',5'-Tri-O-acetyl-N ⁶-(3-hydroxyphenyl) adenosine (IMM-H007), a novel AMPK agonist, has shown protective effects in metabolic diseases. However, its impact on cholesterol and triglyceride metabolism in hypercholesterolemia remains unclear. In this study, we aimed to elucidate the effects and specific mechanisms by which IMM-H007 regulates cholesterol and triglyceride metabolism. To achieve this goal, we used Apoe ^-/- and Ldlr ^-/- mice to establish a hypercholesterolemia/atherosclerosis model. Additionally, hepatocyte-specific Ampka1/2 knockout mice were subjected to a 5-week high-cholesterol diet to establish hypercholesterolemia, while atherosclerosis was induced via AAV-PCSK9 injection combined with a 16-week high-cholesterol diet. Our results demonstrated that IMM-H007 improved cholesterol and triglyceride metabolism in mice with hypercholesterolemia. Mechanistically, IMM-H007 modulated the AMPKα1/2-LDLR signaling pathway, increasing cholesterol uptake in the liver. Furthermore, IMM-H007 activated the AMPKα1-FXR pathway, promoting the conversion of hepatic cholesterol to bile acids. Additionally, IMM-H007 prevented hepatic steatosis by activating the AMPKα1/2-ATGL pathway. In conclusion, our study suggests that IMM-H007 is a promising therapeutic agent for improving hypercholesterolemia and atherosclerosis through the activation of AMPKα.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Biliary tract cancer (BTC) is a rare group of malignancies that develop from the epithelial lining of the biliary tree and have a poor prognosis. Although chemotherapy is the standard of care for patients with advanced BTC in China, its clinical benefits are moderate. In recent years, the approval of targeted therapies and immunotherapies has provided new avenues for the management of advanced BTC. Nonetheless, the increasing number of personalized medicine approaches has created a challenge for clinicians choosing individualized treatment strategies based on tumor characteristics. In this article, we discuss recent progress in implementing precision medicine approaches for advanced BTC in China and examine genomic profiling studies in Chinese patients with advanced BTC. We also discuss the challenges and opportunities of using precision medicine approaches, as well as the importance of considering population-specific factors and tailoring treatment approaches to improve outcomes for patients with BTC. In addition to providing a comprehensive overview of current and emerging precision medicine approaches for the management of advanced BTC in China, this review article will support clinicians outside of China by serving as a reference regarding the role of patient- and population-specific factors in clinical decision-making for patients with this rare malignancy.

Sustained inflammatory responses are closely related to various severe diseases, and inhibiting the excessive activation of inflammasomes and pyroptosis has significant implications for clinical treatment. Natural products have garnered considerable concern for the treatment of inflammation. Huanglian-Wumei decoction (HLWMD) is a classic prescription used for treating inflammatory diseases, but the necessity of their combination and the exact underlying anti-inflammatory mechanism have not yet been elucidated. Inspired by the supramolecular self-assembly strategy and natural drug compatibility theory, we successfully obtained berberine (BBR)-chlorogenic acid (CGA) supramolecular (BCS), which is an herbal pair from HLWMD. Using a series of characterization methods, we confirmed the self-assembly mechanism of BCS. BBR and CGA were self-assembled and stacked into amphiphilic spherical supramolecules in a 2:1 molar ratio, driven by electrostatic interactions, hydrophobic interactions, and π-π stacking; the hydrophilic fragments of CGA were outside, and the hydrophobic fragments of BBR were inside. This stacking pattern significantly improved the anti-inflammatory performance of BCS compared with that of single free molecules. Compared with free molecules, BCS significantly attenuated the release of multiple inflammatory mediators and lipopolysaccharide (LPS)-induced pyroptosis. Its anti-inflammatory mechanism is closely related to the inhibition of intracellular nuclear factor-kappaB (NF-κB) p65 phosphorylation and the noncanonical pyroptosis signalling pathway mediated by caspase-11.

Abstract In recent years, the prevalence of overweight and obesity among children and adolescents has risen rapidly, posing a serious threat to their physical and mental health. To provide scientific, systematic, and standardized weight management guidance for overweight and obese children and adolescents, the study focuses on the core concept of healthy lifestyle intervention, integrates multidisciplinary expert opinions and research findings,and proposes a comprehensive multidisciplinary intervention framework covering scientific exercise intervention, precise nutrition and diet, optimized sleep management, and standardized psychological support. It calls for the establishment of a multi agent collaborative management mechanism led by the government, implemented by families, fostered by schools, initiated by individuals, optimized by communities, reinforced by healthcare, and coordinated by multiple stakeholders. Emphasizing a child and adolescent centered approach, the consensus advocates for comprehensive, multi level, and personalized guidance strategies to promote the internalization and maintenance of a healthy lifestyle. It serves as a reference and provides recommendations for the effective prevention and control of overweight and obesity, and enhancing the health level of children and adolescents.

Objective:To introduce the application of highly selective arterial indocyanine green angiography (hereinafter referred to as highly selective arterial angiography) in the design of anterolateral thigh free flap.Methods:This study was a retrospective observational study. From November 2023 to April 2024, 29 patients with wounds in extremities which were repaired by anterolateral thigh free flaps designed under the assistance of highly selective arterial angiography and met the inclusion criteria were admitted to the Department of Hand Surgery and Department of Wound Repair Surgery of Suzhou Ruihua Orthopedic Hospital, including 26 males and 3 females, aged 16 to 71 years. The wound area after debridement ranged from 8.0 cm×4.5 cm to 27.0 cm×16.0 cm. During the surgery, highly selective arterial angiography was used to assist in flap design. The fluorescence development range of the source arteries or perforators of flaps was observed. The blood supply range of the source arteries or perforators of flaps was determined based on the fluorescence development of the skin, and the excision position of the flap was adjusted. The flap incision area ranged from 9.0 cm×6.0 cm to 29.0 cm×16.0 cm. During the surgery, the number of highly selective arterial angiography, the type of source artery of perforators for puncture, and changes in the excision position of flaps were observed and recorded. After surgery, the blood supply and survival of flaps, the healing of wounds and the survival of skin grafts in the flap donor sites, and the angiography-related complications were observed.Results:All the 32 flaps of 29 patients were successfully excised. The highly selective arterial angiography was performed 37 times, including 13 cases of puncture of the oblique branch of the lateral circumflex femoral artery, 6 cases of puncture of the descending branch, 8 cases of double puncture of the oblique and descending branches, and 2 cases of puncture of arteries from other branches. During the surgery, the excision position of 28 flaps did not change, the excision position of 3 flaps moved towards proximal extremity of the thigh, and the excision position of 1 flap moved towards distal extremity of the thigh. All the flaps survived successfully after the surgery, and there was no partial necrosis of the flaps at the proximal or distal ends. The wounds in the flap donor sites healed, and all skin grafts survived. No angiography-related complications occurred.Conclusions:Highly selective arterial angiography can be used to determine the blood supply range of the source artery and perforators of the anterolateral thigh free flaps during the surgery. It can evaluate the blood supply of flaps more intuitively and objectively. Its application in assisting flap design can avoid partial flap necrosis caused by unreasonable preoperative design to a certain extent, and it is safe and reliable.

Objective:To analyze clinical characteristics of primary pancreatic lymphoma (PPL) patients.Methods:Clinical features of 22 patients diagnosed as PPL admitted to Peking Union Medical College Hospital from January 2002 to May 2023 were analyzed retrospectively.Results:The median age was 56.4±13.3 years. The median time from onset to diagnosis was 1.0 (1.0, 3.0) months. The main clinical manifestations were abdominal pain (15/22), weight loss (14/22) and jaundice (10/22). Elevated lactate dehydrogenase (LDH) was observed in 15/20 (75%) patients. Only 2 (2/9, 22.2%) patients had increased CA199 levels and 2 (2/9, 22.2%) patients had increased CEA levels. The maximum tumor diameter was 5.0 (3.8, 6.9) cm. Contrast-enhanced CT mostly showed low enhancement lesions. Major pancreatic duct dilatation were rare on CT scan (4/20). Fifteen patients were confirmed by pancreatic pathology, of which 8 were obtained by surgery, 4 were obtained by CT or ultrasound-guided percutaneous biopsy, and 3 were obtained by EUS-FNA. The main pathological type was diffuse large B-cell lymphoma (14/22). 19 patients received chemotherapy, and 6 patients died with a median follow-up of 5.0 (1.5, 35.5) months.Conclusions:PPL is rare and easy to be misdiagnosed. Elevated LDH levels, normal tumor markers, and non-dilatation of main pancreatic duct are important diagnostic clues. It is important to obtain pathology by EUS-FNA and other methods for definite diagnosis.

Objective To investigate the clinical significance of the chorda arteriae umbilicalis in laparoscopic transabdominal preperi-toneal(TAPP)hernia repair.Methods The clinical data of 60 patients with inguinal hernia admitted to Xinrui Hospital in Xinwu District of Wuxi City from June 2019 to June 2022 were analyzed,and the patients were randomly divided into two groups according to whether the chorda arteriae umbilicalis was used as a marker during operation.Both the control group and the observation group were operated according to the routine procedure.The observation group exposed the chorda arteriae umbilicalis,which was used as a reference to precisely free the surgical plane and gap to complete the parietalization of spermatic cord,meanwhile,the angle formed by the intersection of the deferens and umbilical artery cord was used to assist in fixing the patch.The operation time,time of parietalization of spermatic cord,hospital stay,bladder surface bleeding volume,removal rate of hernial sac,the occurrence of postoperative complications and recurrence of patients were compared between the two groups.Results There was no significant difference in the operation time,removal rate of hernial sac,hospital stay,recurrence rate or the incidence of postoperative complications such as chronic pain,uroschesis of patients between the two groups(P>0.05).The time of parietalization of spermatic cord,bladder surface bleeding volume,and incidence of seroma of patients in the observation group were shorter/lower than those in the control group,the differences were statistically significant(P<0.05).Conclusion The chorda arteriae umbilicalis has a constant morphology and relatively fixed anatomical position and alignment.The chorda arteriae umbilicalis can be used as a reference and guiding mark,especially when the anatomical layer is dense and unclear or strayed into the layer in TAPP hernia repair,whihc can guide to operate at the correct layer,standardize the parietalization of spermatic cord,reduce bleeding and vice-damage,and also assist the fixation of the patch and prevent the displacement of the patch.
