A total of 360 healthy 26 week old Huaixiang hens were randomly divided into 10 groups,of which,five groups were reared at normal temperature(NC,NT1,NT2,NT3,NT4)and other five groups were reared at high temperature(HC,HT1,HT2,HT3,HT4),all chickens were feed with 0,4,6,8,10 mg/kg canthaxanthin(CX)respectively.The pre-test period was 2 weeks and the main test period was 9 weeks.The results showed that high temperature reduced the egg pro-duction rate(P＜0.05),led to damage and hemorrhage in the ovaries,decreased the activity of su-peroxide dismutase(SOD),glutathione peroxidase(GSH-Px)in the serum and the ovaries(P＜0.05),decreased the levels of FSH,LH,P4,and E2(P＜0.05),decreased the expression of FSHR,LHR,ER,and PR(P＜0.05),and increased the levels of malonaldehyde(MDA)(P＜0.05)in the ovaries.Addition of CX increased the egg production rate(P＜0.05),increased the activity of serum and ovarian SOD and GSH-Px enzymes(P＜0.05),decreased the content of serum and ovarian MDA(P＜0.05)),increased the ovarian levels of FSH,LH,P4,E2(P＜0.05),and increased the o-varian expression of FSHR,LHR,ER,and PR(P＜0.05)in Huaixiang chickens at normal and high temperature environmental conditions,respectively.Among them,the highest egg production rate,the strongest antioxidant capacity of serum and ovarian tissues,the best integrity of ovarian tis-sues,ovarian reproductive hormone secretion and expression of reproductive hormone receptors were observed in Huaixiang chickens when 6 mg/kg of CX was added to the diet under normal temperature and when 8 mg/kg CX was added to the diet under high temperature conditions.The results showed that under normal and high temperature conditions,adding CX to the diet signifi-cantly increased the antioxidant capacity of serum and ovaries,alleviated the damage of ovary,pro-moted the secretion of reproductive hormone and the expression of reproductive hormone recep-tors,and increased egg production rate.Dietary supplemented with CX could not restore the dam-age and repair of ovarian tissue,the secretion of reproductive hormone and receptor to normal tem-perature level.The effects of CX on egg production rate,ovarian tissue structure,reproductive hor-mone and receptor expression in chickens were affected by the environmental temperature.When the egg production rate,antioxidant capacity of ovarian tissues,reproductive hormone levels and receptor expression of Huaixiang chickens were optimal,the amount of CX in high temperature en-vironment was more than that of the dose in normal temperature environment.

Objective To investigate the relationship between the expression of cyclophilin B(PPIB)in glioma and clinicopatholog-ical features,patient survival,and the infiltration of tumor-associated macrophages.Methods Based on the Cancer Genome Atlas(TCGA)database,the expression of PPIB in normal,low-grade,and high-grade gliomas was compared,and the expression of PPIB in glioma pathological tissues was detected by immunohistochemical staining.Based on the clinical case data of TCGA database,the relation-ship between PPIB expression and clinicopathological features of glioma was analyzed.Kaplan-Meier method was used to evaluate the im-pact of PPIB expression differences on the survival of glioma patients.Immunofluorescence method was used to analyze the expression of PPIB in the pathological tissues of glioma and its correlation with the infiltration of tumor-associated macrophages.Results The expres-sion of PPIB in high-grade glioma was significantly higher than that in normal tissue and low-grade glioma;PPIB was significantly cor-related with glioma grade,IDH wild type,and 1p/19q non-co-deletion(P＜0.001).The overall survival and progression-free inter-val of patients with high expression of PPIB were lower than those of patients with low expression of PPIB.In addition to the elevated ex-pression of PPIB in the pathological tissues of high-grade glioma,the high-expression area of PPIB was accompanied by a large number of tumor-associated macrophage infiltration.Conclusion Compared with low-grade gliomas,the expression levels of PPIB were higher in high-grade gliomas,and there were significant tumor-associated macrophage infiltration in PPIB-expressing areas.It is suggested that PPIB may serve as an independent prognostic factor for patients with glioma,providing reference for the prognosis of patients judg-ment.

Objective To construct adenoviral Ad-pki-67-E1 A-GFP containing the promoter of the ki-67gene to achieve replication specifically in ki-67-positive glioma cells.Methods The promoter sequence of the ki-67gene was cloned into the pGL3-basic vector using molecular biology methods.The ki-67 promoter activity was detected by the dual luciferase reporter gene as-say.The ki-67 promoter was constructed into a shuttle plasmid and co-transfected with a helper plasmid in 293 T cells to recombinant adenovirus Ad-pki-67-E1A-GFP.The Ad-pki-67-E1A-GFP was added to glioma cells,and the expression of GFP was ob-served by fluorescence microscopy.Meanwhile,the expression of ki-67gene,the expression of E1A gene,which was essential for adeno-virus replication,and the number of virus copies were detected by real-time fluorescence quantitative polymerase chain reaction(PCR).Results The cloned ki-67sequence was able to activate reporter gene expression in glioma cells;enzymatic digestion and sequencing demonstrated that the ki-67 promoter was constructed into a shuttle plasmid and recombined to obtain the adenovirus Ad-pki-67-E1A-GFP.Ad-pki-67-E1A-GFP could infect glioma cells,and the expression of E1A and the number of virus copies were posi-tively correlated with the expression of ki-67 in the cells.Conclusion The ki-67 promoter-modified adenovirus replicated in glioma cells,providing a basis for further modification for gene therapy of malignant gliomas.

Objective To analyze the influence of shaping on the bending strength of bone plates and the influence of different locking nail distributions on plate force to provide biomechanical references for shaping plates and selecting different locking nail distributions.Methods Finite element simulation analysis of the four-point bending strength of a plate was performed according to the YY/T 0342-2020 standard.Theoretical analysis and finite element simulation method were used to analyze the force on prosthesis models with different lock-nail distributions.Results At 30° bending,the 3.7 mm-thick plate had 28%higher equivalent plastic strain than the 2.7 mm-thick plate.The 3.7 and 2.7 mm-thick plates had ultimate bending angles of 55° and 67°,respectively.The crease had little impact on the plate stress.The four-point bending strength and equivalent bending stiffness of the unshapeed structure were 2.64 N·m and 1.12 N·m2,respectively.The four-point bending strength and equivalent bending stiffness with the crease were 2.63 N·m and 1.10 N·m2,respectively.After forward and backward bending,the four-point bending strength of the plate decreased from 2.64 to 2.45 N·m by approximately 7.72%,and the equivalent bending stiffness decreased from 1.12 to 0.98 N·m2 by approximately 12%.The impact was obvious.After implantation of tamponade screws,the four-point bending strength of the single-hole plate improved significantly from 2.64 to 3.15 N·m,by approximately 19.32%and the equivalent bending stiffness increased from 1.12 to 1.14 N·m2,by approximately 2.1%.At least two locking holes were reserved on both sides of the fracture line.Not inserting the locking screw reduced the stress by approximately 50%compared with the full insertion of the locking screw.During 15-week postoperative walking without bone callus formation,the material stress of TC4 reached 852.7 MPa and yielding occurred.Conclusions In a clinical scenario where larger shaping is required,it is not suitable for plates with larger thicknesses and plate fractures are more likely to occur after large-thickness shaping.This can guide the clinical selection of plates with appropriate thickness based on the shaping angle,and tamponade screws can be implanted in extreme cases.Fixing locking screws clinically is recommended;however,a method of fixing the locking screws with full screws is not recommended.The biomechanical effect is best when two locking holes at both ends of the fracture line are maintained without fixing the locking screws.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

ObjectiveTo support intelligent clinical decision-making in traditional Chinese medicine（TCM）， this study utilized ontology and knowledge graph construction techniques to achieve the IT application of clinical practice guidelines. MethodBased on the principles of findability， accessibility， interoperability， and reusability （FAIR principles）， this study employed ontology techniques to construct an ontology for TCM clinical practice guidelines and built a knowledge graph using coronary heart disease as an example. Based on the Checklist for Reporting Practice Guidelines in Traditional Chinese Medicine and Recommendation Grading in TCM Clinical Guidelines/Consensus （T/CAS 530—2021），the ontology of TCM clinical practice guidelines was constructed using the seven-step ontology construction method. On this basis，the TCM diagnosis and treatment data from the Guidelines for the Diagnosis and Treatment of Stable Angina Pectoris in Coronary Heart Disease were stored in Neo4j in the form of triples through knowledge extraction，integration，and storage. ResultThe information in the clinical practice guidelines was divided into three categories： onset and prevention information， diagnosis information， and treatment information， and the TCM clinical practice guideline ontology was constructed. A total of 27 concepts related to TCM clinical diagnosis and treatment and 14 data attributes were obtained， and 12 conceptual relationships including hierarchical relationships and object attributes were established. By taking coronary heart disease as an example and the TCM clinical practice guideline ontology as the model layer， the knowledge map of TCM diagnosis and treatment guidelines for stable angina pectoris in coronary heart disease with 276 nodes and 336 relationships was constructed， realizing the visual display and query of the guideline content. ConclusionThe ontology of TCM clinical practice guidelines and the knowledge graph of stable angina pectoris in coronary heart disease constructed by combining the seven-step ontology construction method and Neo4j graph database technology are efficient and flexible，providing an intelligent TCM diagnosis and treatment scheme and promoting the standardization and objectification of TCM diagnosis and treatment.

Objective:To assess the effects of nutritional interventions combined with Traditional Chinese Med-icine(TCM)physical dialectics on the development of gestational diabetes mellitus(GDM),dietary status during pregnancy,and maternal and infant outcomes in high-risk pregnant women in early pregnancy.Methods:298 high-risk pregnant women with GDM in early pregnancy(gestational week≤14 weeks)registered in the Obstet-rics Department of Urumqi Maternal and Child Health Hospital from 1st December 2022 to 30th March 2023 were selected as the study subjects and randomly divided into the intervention group(149 cases)and the control group(149 cases).During 14 to 23+6 weeks of pregnancy,TCM constitution nutritional intervention was carried out for pregnant women in the intervention group,and routine guidance and healthy dietary education was carried out in the control group.The incidence of GDM in the two groups was compared at 24-28 weeks of pregnancy,and the relationship between early pregnancy nutritional intervention combined with TCM constitution and the risk of GDM was analysed in subgroups using logistic regression and likelihood ratio test.The dietary situation,biochemical in-dexes and delivery outcomes after the intervention were compared at 32-36 weeks of pregnancy.Results:①The incidence of GDM in the intervention group was significantly lower than that in the control group(14.09％vs.23.49％,P＜0.05).The effect of the TCM constitution based nutritional intervention on the risk probability of GDM was statistically significant only among pregnant women with different ranges of gestational weight gain(GWG)(P=0.018).Among them,pregnant women with GWG lower than the recommended range had a reduced risk of GDM after intervention(OR 0.27,95％Cl 0.10-0.68,P=0.008).② After intervention,the evaluation index of di-etary balance index of pregnant women in the intervention group was better than that of the control group(P＜0.05),and the intake of cereals and potatoes,vegetables,and water of pregnant women in late pregnancy in the intervention group was higher than that of the control group(P＜0.05).③The levels of triglycerides,total choles-terol,low-density lipoprotein,glycated haemoglobin,uric acid and creatinine of pregnant women in the intervention group were lower than those of the control group in late pregnancy(P＜0.05).GWG,gestational age at delivery,the rate of low-birth-weight,and the neonatal 1-minute Apgar scores were all better than those of the control group(P＜0.05.Conclusions:Nutritional interventions in early pregnancy combined with TCM constitution can sig-nificantly reduce the incidence of GDM in high-risk pregnant women and the chances of low-birth-weight babies.Obstetrics outpatient clinics can actively develop extensive collaboration with TCM and clinical nutrition depart-ments to reduce adverse pregnancy outcomes for both mother and fetus.
