OBJECTIVE: To evaluate the effectiveness of tibial nerve transection with epineurial suture and division of the common plantar digital nerve branches in the treatment of congenital macrodactyly in children. METHODS: A retrospective analysis was conducted on clinical data from 9 children with congenital macrodactyly who met the selection criteria and were admitted between January 2018 and December 2024. The cohort included 4 boys and 5 girls, aged 1-6 years (median, 3 years). Syndactyly of the second and third toes was present in 2 patients. Hypertrophy distribution was as follows: 1 case of single-ray involvement, 4 of double-ray, 1 of triple-ray, 1 of quadruple-ray, and 2 of quintuple-ray. Preoperatively, 7 cases exhibited limitations in both active and passive flexion and extension of the affected toes; in 2 cases, active movement was restricted while passive motion remained intact. All 9 children were unable to wear standard-sized footwear for the unaffected foot. Six presented with a limp, and 3 had difficulty walking. All 9 cases were moderate to severe progressive macrodactyly, and the growth rate of the affected foot was significantly faster than that of the healthy side. Six cases had undergone prior surgical interventions at other institutions, but disease progression continued postoperatively. All 9 patients underwent tibial nerve transection with epineurial suture and selective division of the common plantar digital nerve branches. At last follow-up, the foot growth rate was calculated (compared with that immediately after operation), and the changes of plantar pain sensation in the affected foot were detected before operation, immediately after operation, and at last follow-up, and the surgical efficacy was evaluated based on improvements in shoe fit and gait function. RESULTS: All 9 children were followed up 6-36 months, with an average of 18 months. All the incisions healed by first intention, and no infection or plantar ulceration occurred. At last follow-up, the growth rate of the affected foot was 0.10 (0.04, 0.14) cm/month, which was significantly slower than that of the healthy foot [0.14 (0.08, 0.18) cm/month] ( Z=3.951, P<0.001). Preoperatively, plantar pain sensation was absent in all cases; it was restored immediately after operation. At last follow-up, 6 patients had absent pain sensation, 2 had partial preservation (involving certain toes and central plantar regions), and 1 patient (with 3-year follow-up) exhibited regained sensation in multiple plantar areas. Gait improved in most cases, in which 8 children achieved normal ambulation, while 1 continued to limp due to leg-length discrepancy. Surgical efficacy were rated as excellent in 1 case, good in 7, and fair in 1. CONCLUSION Tibial nerve transection with epineurial suture combined with selective division of the common plantar digital nerve branches effectively reduces the growth rate of congenital macrodactyly in children, has minimal impact on plantar sensory function, and does not result in plantar ulcers or impaired ambulation.

Objective To explore the effect of the ratio of high-density lipoprotein cholesterol(HDL-C)/total cholesterol(TC)on no-reflow after percutaneous coronary intervention(PCI)in elderly patients with acute coronary syndrome(ACS)complicated with diabetes mellitus(DM).Methods A retrospective analysis was conducted on 206 elderly ACS patients complicated with DM undergoing PCI in our hospital from January 2018 to August 2024.The HDL-C and TC levels were detected by cholesterol oxidase test,and the HDL-C/TC ratio was calculated.Coronary angi-ography(CAG)was applied to evaluate no-reflow phenomenon after PCI,and according to the re-sults,the patients were divided into a non-reflow group(41 cases)and a normal reflow group(165 cases).ROC curve was plotted to evaluate the predictive performance of HDL-C/TC ratio for no-reflow after PCI in patients with ACS complicated DM.Results The no-reflow group had signifi-cantly higher TC and glycated hemoglobin A1c(HbA1c)levels and more balloon dilatations,but lower HDL-C level and HDL-C/TC ratio than the normal flow group(P＜0.01).Multivariate lo-gistic regression analysis showed that HbA1c(OR=3.196,95％CI:1.619-6.310,P=0.001),number of balloon dilatations(OR=3.504,95％CI:1.807-6.797,P=0.000),and HDL-C/TC ra-tio(OR=3.927,95％CI:2.0 73-7.441,P=0.000)were influencing factors of no-reflow after PCI in patients with ACS and DM.The AUC value of HDLC,TC,and HDL-C/TC ratio in predicting no-reflow after PCI was 0.842,0.726,and 0.922,respectively.Conclusion HDL-C/TC ratio is an influencing factor for no-reflow in patients with ACS and DM after PCI.The ratio at a cut-off val-ue of ≤0.21 has a certain predictive value for no-reflow after PCI in these elderly patients.

Objective:To evaluate the effect of remimazolam tosilate on postoperative delirium (POD) in elderly patients undergoing urological surgery.Methods:In this randomized controlled trial, 220 American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ elderly patients of either sex, aged≥65 yr, with body mass index of 18-28 kg/m 2, scheduled for elective urological surgery under general anesthesia, were divided into 2 groups ( n=110 each) using a random number table method: propofol group (group P) and remimazolam tosilate group (group R). Group P received propofol 1.0-1.5 mg/kg for induction and propofol 2-6 mg·kg -1·h -1 for maintenance, while group R received remimazolam tosilate 0.2-0.3 mg/kg for induction and remimazolam tosilate 0.5-1.2 mg·kg -1·h -1 for maintenance. The other drugs for induction and maintenance were the same in the two groups. POD was assessed using the Chinese version of the 3-minute diagnostic interview for Confusion Assessment Method within 3 days after surgery in the two groups. The intraoperative consumption of remifentanil and usage of vasoactive drugs, extubation time, 15-item Quality-of-Recovery scale scores at 24 h after operation, requirement for rescue analgesia within 24 h after operation, and postoperative adverse effects were recorded. Results:There were no significant differences in the incidence of POD within 3 days after operation, 15-item Quality-of-Recovery scale scores at 24 h after operation, or rate of rescue analgesia within 24 h after operation between two groups ( P>0.05). Compared with group P, the requirement for intraoperative vasoactive drugs was significantly reduced, the extubation time was shortened, and the incidence of hypoxemia was decreased within 24 h after operation in group R ( P<0.05 or 0.001). Conclusions:Remimazolam tosilate has no marked effect on the occurrence of POD in elderly patients undergoing urological surgery.

Objective:To explore the impacts of 131I-NaI radiotherapy on the promotion of glycolysis and 18F-fluorodeoxyglucose ( 18F-FDG) uptake in pancreatic cancer cells via the induction of proviral integration moloney murineleukemia virus 2 (PIM2) and 6-phosphofructo-2-kinase/fructose-2, 6-biphosphatase 3 (PFKFB3). Methods:In the cell experiments, human pancreatic carcinoma cells-1 (PANC-1) were randomly divided into four groups: a control group, an HJ-PI01 group, a 131I-NaI group, and an HJ-PI01 + 131I-NaI group. Their aerobic glycolysis capacity was assessed by measuring glucose uptake, lactate production, and extracellular acidification rate (ECAR). In vivo animal experiments, 12 nu/nu female nude mice were given 100 μl (1 × 10 7 cells) of cell suspension through subcutaneous injection into the left lower limbs. When the tumor volume reached approximately 60 mm 3, these mice were divided into four groups (a control group, a HJ-PI01 group, a 131I-NaI group, and an HJ-PI01+ 131I-NaI group) using a random number table, with three mice in each group. After 14 days of treatment, 18F-FDG PET/CT imaging was performed to calculate the maximum standardized uptake value (SUV max) of the xenografts. Following PET/CT imaging, the tumor tissues were harvested and analyzed for PIM2, PFKFB3, and Ki-67 expressions using immunohistochemistry. Results:In cell experiments, compared to the control group, the HJ-PI01 group exhibited significant reduction in glucose uptake, lactate production, PFKFB3 protein expression, and ECAR in PANC-1 cells ( t = 4.59-13.98, P < 0.05). In contrast, the 131I-NaI group showed significant increases in these parameters ( t = 3.36-13.97, P < 0.05). Compared to the 131I-NaI group, the HJ-PI01+ 131I-NaI group showed significant reduction in glucose uptake, lactate production, PFKFB3 protein expression, and ECAR ( t = 5.14-20.87, P < 0.05). In the animal experiments, compared to the control group, the three groups displayed significant decrease in SUV max of 18F-FDG uptake in tumors ( t = 16.48, 22.49, 32.64, P < 0.001). Moreover, the HJ-PI01 + 131I-NaI group exhibite significantly lower SUV max than the 131I-NaI group ( t = 10.16, P < 0.001). Immunohistochemical analysis revealed that the HJ-PI01+ 131I-NaI group, compared to the 131I-NaI group, showed significantly lower Ki-67 expression and the PIM2/PFKFB3 signaling pathway in tumor tissues ( t = 3.27, 10.73, 14.85, P < 0.05). Conclusions:Glycolysis enhancement of PANC-1 cells, mediated by the PIM2/PFKFB3 signaling pathway inhibition, can significantly improve the anticancer capacity of 131I-NaI, providing a novel strategy for radiotherapy in pancreatic cancer.

Objective To analyze the influencing factors of plastic bronchitis in children with Mycoplasma pneumoniae infection and put forward targeted prevention suggestions. Methods The clinical data of children with Mycoplasma pneumoniae infection who were admitted to Chengdu Third People's Hospital from September 2022 to February 2024 were retrospectively analyzed . According to whether plastic bronchitis occurred, they were divided into plastic group (n=118) and non-plastic group (n=184), and the differences between the two groups were compared and analyzed. Univariate and multivariate logistics regression analysis equations were used to analyze the independent influencing factors of plastic bronchitis in children with mycoplasma pneumoniae infection. Results Among the 302 children with Mycoplasma pneumoniae infection , 118 cases were diagnosed with plastic bronchitis. Analysis showed that the children’s age, duration of fever, hospital stay, pleural effusion rate, number of bronchoscopic lavage, allergy history, endoscopic mucosal erosion rate, WBC, NE%, LY%, CRP, LDH, PCT and D-D were the single factors influencing the occurrence of plastic bronchitis in children with mycoplasma pneumoniae infection. Binary logistics regression analysis revealed that age (OR=2.137, P=0.033, 95% CI: 1.132-16.603), allergy history （OR=3.028, P=0.014, 95% CI: 1.261-864), NE% (OR=2.395, P=0.031, 95% CI: 1.087-5.274), CRP (OR=3.864, P=0.004, 95% CI: 1.563-3.864), PCT (OR=4.125, P=0.001, 95% CI: 1.793-3.864), and D-D (OR=3.920, P=0.002, 95% CI: 1.632-3.864) were independent risk factors for plastic bronchitis in children with mycoplasma pneumoniae infection (P<0.05). Conclusion Age, allergy history, NE%, CRP, PCT and D-D are independent risk factors for plastic bronchitis in children with mycoplasma pneumoniae infection . It is necessary to take clinical intervention measures to reduce the occurrence risk.

Objective:To compare the localization accuracy of interictal 18F-FDG and 18F-flumazenil (FMZ) PET/CT imaging for focal cortical dysplasia (FCD). Methods:A retrospective analysis was conducted on 22 patients (12 males, 10 females; age 8-36 years) with pathologically confirmed FCD who underwent surgical resection at Huashan Hospital, Fudan University from July 2021 to June 2023. All patients underwent 18F-FDG and 18F-FMZ PET/CT scans before surgery. Surgical pathological diagnosis was used as the gold standard. Visual scoring was used to analyze the images. The accuracy of the two imaging methods in the localization of FCD was compared, and subgroup analysis (FCD Ⅱa, FCD Ⅱb) of different pathological type was further performed. Paired- t test, χ2 test or Fisher′s exact test was used to analyze the data. Results:The visual score of 18F-FMZ PET/CT was higher than that of 18F-FDG (3.00±0.82 vs 2.27±0.92; t=4.17, P=0.020). The accuracy of interictal 18F-FMZ PET/CT was 77.27%(17/22), which was higher than that of 18F-FDG PET/CT (36.36%, 8/22; χ2=7.50, P=0.006). Subgroup analysis showed that within the cohort of patients diagnosed with FCD Ⅱa ( n=18), 18F-FMZ PET/CT outperformed 18F-FDG in terms of accuracy for localization (15/18 vs 6/18; P=0.006). Conclusion:Compared to 18F-FDG, 18F-FMZ PET/CT demonstrates clearer and more accurate identification of lesion borders, and exhibits higher precision, which provides valuable guidance for preoperative localization.

Critical care medicine-related treatment is an interdisciplinary and multi-professional process,often leading to secondary or concomitant mental disorders in clinical practice.Currently,there is no consensus on the pharmacological treatment of related mental illnesses in China.The Chinese Society of Psychosomatic Medicine collaborated with the Critical Care Medicine expert group to form a consensus writing expert group.After a systematic review of relevant literature,summarizing published domestic and foreign literature,and extensive discussions,the consensus was developed.The consensus elaborates on the principles and processes of the standardized use of psychotropic drugs in critical care medicine,as well as the clinical indications,precautions,and specific drug selection of various psychiatric medications,providing feasible suggestions and guidance for the clinical application of psychiatric medications in the intensive care unit.
