Objective To systematically review the studies on predictive models for delayed graft function (DGF) after kidney transplantation. Methods Databases including China Biology Medicine Database, China National Knowledge Infrastructure, Wanfang Database, VIP Database, PubMed, Web of Science and CINAHL were searched to collect studies on predictive models for DGF after kidney transplantation published from the establishment of each database to June 29, 2025. Two researchers screened the literatures according to the inclusion and exclusion criteria, evaluated the quality of the literatures using the prediction model risk of bias assessment tool (PROBAST), and conducted a meta-analysis of the common predictors of the models using R software. Results A total of 12 literatures were included, involving 14 predictive models with sample sizes ranging from 103 to 24 653 cases. Donor serum creatinine level, cold ischemia time, donor age and donor body mass index were the top four common predictors. All the predictive models were at high risk of bias and low in applicability. The results of meta-analysis showed that abnormal donor body mass index, advanced donor age, prolonged cold ischemia time and elevated donor serum creatinine level were all associated with an increased risk of DGF after transplantation (all P<0.01), but there was high heterogeneity among the studies. Fixed-effect model and random-effect model were used to re-pool the effect sizes separately. The results indicated that the fixed-effect model and random-effect model had good consistency in terms of donor body mass index, donor age and cold ischemia time, while there was a significant difference in the effect sizes of the two models for donor serum creatinine level. Conclusions The predictive models for DGF risk after kidney transplantation have good predictive performance, but the overall risk of bias is high. In the future, large-sample, multicenter and high-quality prospective clinical studies should be carried out to optimize the predictive models, so as to improve their predictive ability and clinical application value.

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.

Objective To investigate the impact of total parathyroidectomy with autotransplantation (tPTx+AT)on bone mineral density and serum soluble Klotho (sKlotho)level in patients with secondary hyperparathyroidism (SHPT).Methods A total of 86 patients undergoing tPTx+AT in the Second Affiliated Hospital of Anhui Medical University from June 2019 to May 2022 were recruited in this study.Their demographic characteristics were collected before surgery,along with serum levels of corrected calcium,phosphorus,intact parathyroid hormone (iPTH),alkaline phosphatase (ALP),fibroblast growth factor 23 (FGF23),and sKlotho before and at 5 d,and 1,3,6,12 and 24 months after surgery.Dual energy X-ray absorptiometry was used to determine the BMD values of the lumbar spine L1-L4 before surgery and at 3,6,12 and 24 months after surgery.The changes in BMD and serum FGF23 and sKlotho levels before and after tPTx+AT were observed.Results Surgical treatment was successfully completed in all 86 patients,with their clinical symptoms such as bone pain and skin itching significantly improved postoperatively,and markedly decreased serum calcium,phosphorus,iPTH,ALP and FGF23 levels.The sKlotho level was significantly lower at 5 d postoperatively than that preoperatively,with that at 1 month after surgery increased by approximately 24.5％ than the preoperative level,and then the level was in a stable trend.The BMD values at the lumbar spine L1-L4 were increased postoperatively,and reached the highest levels at 12 months postoperatively.Further analyses showed that dialysis vintage,duration of SHPT,and ALP,iPTH and FGF23 levels were negatively correlated with the Z-scores of the lumbar spine L1-L4,while sKlotho level was positively correlated with the Z-scores.Conclusion tPTx+Atcan significantly improve the clinical symptoms of SHPT patients,regulate the balance of calcium and phosphorus metabolism,increase sKlotho level and reduce FGF23 level.It is an effective method to improve BMD.

Objective:To investigate the clinical value of shear wave elastography (SWE) in predicting pathological responses to neoadjuvant chemotherapy in breast cancer.Methods:According to the postoperative pathological responses, 56 patients who received neoadjuvant chemotherapy followed by surgical excision in the Fujian Cancer Hospital from August 2019 to September 2020 were divided into responders and non-responders. The relative change rates of tumor maximum diameter(ΔD2, ΔD4) and SWE stiffness (ΔEmax2, ΔEmax4, ΔEmean2, ΔEmean4) were assessed before NAC and after different NAC cycles (t2, t4). Clinical information, including age, T, N stages, ER, PR, HER2, Ki67, and molecular subtype were also considered as the variables. The independent influencing factors of pathological responses after neoadjuvant chemotherapy were obtained by logistic regression analysis and diagnostic test was carried out.Results:There were 23 cases as responders (41.0%, 23/56), and 33 cases as non-responders (58.9%, 33/56). Results of multivariate analysis showed ΔEmax4 and HER2 index were independent influencing factors of pathological responses ( OR=1.11, P<0.001; OR=31.81, P=0.002). Area under curve of the ΔEmax4 (AUC: 0.869, 95% CI: 0.746-0.941) was higher than that of HER2 (AUC: 0.690, 95% CI: 0.545-0.834). The combination of ΔEmax4 and HER2 gave the best prediction of pathological responses (AUC 0.930, 95% CI: 0.829-0.981). the sensitivity, specificity, diagnostic accuracy, postive predictive value, and negative predictive value were 78.26%, 96.97%, 75.23%, 94.73%, and 86.49%, respectively. Conclusions:ΔEmax4 and HER2 are independent predictors of pathological responses after neoadjuvant chemotherapy for breast cancer. Combined ΔEmax4 and HER2 can improve the predictive diagnostic efficacy of pathological responses to chemotherapy for breast cancer.

Objective: To establish an accurate and selective UPLC-MS/MS) method for the determination of afatinib in rat plas-ma. Methods: Protein precipitating by acetonitrile was used to prepare the samples. A CORTECS BEH C18column ( 50 mm × 2. 1 mm, 1. 6 μm) was used to separate the analytes at 40℃. The mobile phase consisted of acetonitrile and water (0. 1% formic acid) with the flow rate of 0. 4 ml·min-1. The analytes were quantified by multiple reaction monitoring ( MRM) mode with positive electrospray ionization, while the target fragment ions were m/z 486. 19→112. 1 for afatinib and m/z 557. 3→112. 15 for neratinib (IS). Results: The calibration curve obtained good linearity for afatinib within the range of 1–200 ng·ml-1(r=0. 998 1), and the LLOQ in rat plasma was 1. 0 ng/ml. The intra-and inter-day precisions were both≤9. 51% . The recovery of afatinib from plasma was above 77. 1% . After intragastric administration and intravenous administration of afatinib in rats, the t1/2was 7. 19 h and 2. 69 h, Cmax was 97. 78 ng·ml-1and 123. 37 ng·ml-1,and AUC(0-∞)was 1 505. 4 ng·ml-1·h and 405. 55 ng·ml-1·h, respectively. Con-clusion: The validated method can be applied in the pharmacokinetic study of afatinib at the intragastric and intravenous dosage of 10 and 2 mg·kg-1, respectively.

Objective To explore the correlation of total IgE and childhood atopic dermatitis (AD) in maternal serum and newborn cord blood, as well as its clinical significance of allergen testing. Methods Thirty-five cases diagnosed as AD (AD group) were selected, and other 35 children who were not diagnosed as AD (control group) were randomly selected from a birth cohort established in 2009—2011. The total IgE levels were detected by ELISA in maternal serum and newborn cord blood. The serum specific IgE antibody level was detected by quantitative immunoblotting method. Results The serum total IgE level was significantly higher in mother and newborn cord blood in AD group than that in control group (χ2=16.568 and 14.933, P<0.01). Compared to control group, there was a significantly higher positive rate of mother serum allergen includ?ing dust mites, house dust, ragweed pollen, song kind of pollen, poplar, surname and elm pollen, mould, shrimp, marine fish, in AD group (P<0.05). There was a significantly higher positive rate of artemisia pollen and fungi IgE in newborn cord blood in AD group (P<0.05). Conclusion The increased total IgE in maternal serum may play a predictive effect on infants suf?fering from AD. There is no obvious consistency in allergic state between mothers and infants.

A total of 127 type 2 diabetic patients were divided into low glycemic index meal replacements (intervention) group and standard food-based diet (reference) group in an experiment for 12 weeks.The results showed that fasting plasma glucose,postprandial 2 h plasma glucose,fasting insulin,and homeostasis model assessment insulin resistance(HOMA-IR) in the intervention group decreased significantly after 12 weeks trial ( P＜0.05 or P＜0.01 ).However,there were no significant changes in lipid profile and HbA1C in intervention group.In addition,percentage of body fatty,visceral fatty area,and waist-hip ratio also decreased in intervention group( all P＜0.01 ).Superoxide dismutase and glutathione levels increased significantly in intervention group by the end of trial (both P＜0.01 ),while malondialdehyde was decreased (P＜0.01 ).There were no significant changes in the aforementioned indices in the reference group.Weight,body mass index,and waist circumferences were decreased in both groups,but without significant difference between the two groups.

Objective To explore the possible correlation between HbA1c level and nutritional status in community.based patients with type 2 diabetes.Methods A totaI of 219 type 2 diabetes patients were assigned into 2 groups:one with HbAIc<6.5%(n:108)and HbA1f≥6.5%(n=111).Metabolic parameters,food components.and nutritional status were compared between 2 groups.Results (1)49.32% of the participants attained HbA1c<6.5%.(2)HbA1c level was positively correlated with fasting plasma glucose,postprandial plasma glucose,and homeostasis assessment for insulin resistance(HOMA-IR)(r were 0.56,0.49,and 0.20,respectively,P<0.05 or P<0.01),but negatively correlated with high-density lipoprotein-cholesterol(HDL-C)(r=0.16,P<0.05).(3)Linear regression analysis showed that energy,carbohydrate,protein,and fat were the independent risk factors of HbA1c(all P<0.05).(4)Patients with HbA1c<6.5%consumed more fruits.The intake of pure energy-providing foods and protein-,fat-,or saturated fatty acid-rich foods were more frequent in patients with HbA1c≥6.5%(P<0.05).(5)The linear regression revealed that HbA1c level were decreased 0.36%(P<0.10)or 0.46%(P<0.01)by intake of more fruits,roughage and beans,and HbA1c levels were also decreased 0.42%(P<0.05)or 0.37%(P<0.10)by intake of less meat or oils.Conclusions In communitybased patients with type 2 diabetes mellitus,the incidence of HbA1c<6.5% remains low,There exists great difference in nutritional status between the groups with high and low HbA1c levels.The impact of diet OB HbA1c level is great.It's necessary to emphasize the importance of diet therapy far better diabetes control.
