Objective To establish a genetic monitoring method for laboratory quails.Methods Quail microsatellite loci were searched in the literature,and microsatellite DNA loci suitable for quails were screened by an interspecific transfer method in closely related species,namely chickens and ducks.Quail liver DNA was extracted as a template,and the corresponding loci were screened by PCR amplification and agarose gel electrophoresis.On the basis of amplification of the selected microsatellite loci,the number of alleles,polymorphisms,and microsatellite loci combinations for quail genetic quality detection were selected and detection method were developed.Results We preliminary determined 23 microsatellite loci for genetic monitoring of closed-colony laboratory quails.Conclusions A genetic monitoring method for laboratory quails was preliminary developed.

Objective:To compare the clinical outcomes between percutaneous Kirschner wire leverage plus plaster fixation and elastic intramedullary nailing in the treatment of radial neck fractures in children.Methods:A retrospective study was conducted to analyze the 60 children with radial neck fracture who had been treated by percutaneous Kirschner wire leverage plus plaster fixation at Department of Pediatric Orthopedics, Children's Hospital of Soochow University from January 2016 to July 2023 (set as an internal fixation-free group). They were 30 males and 30 females (34 left and 26 right sides) with an age of (7.7±3.0) years. At the same time, another cohort of 60 patients were chosen as an intramedullary nailing group who had been treated by percutaneous Kirschner wire leverage plus elastic intramedullary nailing and matched in age and gender with those in the internal fixation-free group. The preoperative fracture angulation, operative time, hospitalization time, fracture angulation on the first postoperative day, fracture angulation at 1 month postoperatively, rate of angulation loss after reduction, Mayo elbow performance score (MEPS) at the last follow-up and complications were compared between the 2 groups.Results:There was no significant difference between the 2 groups in their preoperative general data, showing comparability ( P<0.05). The 120 pediatric patients were followed up for (7.5±3.2) months. The operative time [(27.4±15.0) min] and hospitalization time [(3.4±1.9) d] in the internal fixation-free group were significantly shorter than those in the intramedullary nailing group [(45.4±13.5) min and (4.4±1.3) d] ( P<0.05). The preoperative fracture angulation (50.8°±1.9°), fracture angulation on the first postoperative day (11.3°±1.2°), fracture angulation at 1 month postoperatively (12.1°±1.3°), rate of angulation loss after reduction (2.9%±0.5%), and MEPS at the last follow-up [(90.4±2.0) points] in the internal fixation-free group showed no significant differences from those in the intramedullary nailing group [49.5°±1.7°, 11.1°±1.2°, 13.3°±1.5°, 3.9%±1.4%, and (90.2±2.3) points] ( P>0.05). None of the patients in the internal fixation-free group developed pin-tail irritation sign or premature epiphyseal closure after surgery, whereas 3 patients in the intramedullary nailing group developed pin-tail irritation sign and 2 ones premature epiphyseal closure after surgery, showing a significant difference in the complication rate between the 2 groups [0 (0/60) versus 8.3% (5/60)] ( P<0.05). Conclusions:Percutaneous Kirschner wire leverage plus plaster fixation and close elastic intramedullary nailing can both achieve satisfactory outcomes in the treatment of radial neck fractures in children. However, percutaneous Kirschner wire leverage plus plaster fixation needs shorter operative time and hospitalization time, leads to fewer complications, and requires no reoperation to remove internal fixation.

Post traumatic depression (PTD) is a serious complication after traumatic brain injury, with high incidence rate; PTD seriously affects the rehabilitation, outcome and quality of life of patients. Due to unclear pathogenesis of PTD, effective treatments have not yet been found in clinical practice. Repetitive transcranial magnetic stimulation (rTMS), as a new non-invasive neuroregulatory technique, has been used in major depression disorder (MDD). Few clinical evidence on PTD treated by rTMS is noted and optimal rTMS treatment regimen has not yet been defined.This article reviews the clinical studies of rTMS in PTD in recent years, with a view to provide references for clinical application.

Objective To investigate the effect of cornus officinalis glycosides on apoptosis and oxidative damage of human renal tubular epithelial cells line induced by high glucose by regulating E2-related factor 2(Nrf2)/heme oxygenase-1(HO-1)pathway.Methods Human renal tubule epithelial cell line HK-2 was divided into control group(control,5.5 mmol/L glucose),model group(HG,30 mmol/L glucose),and total cornus offici-nalis glycosides groups with low,medium and high dose(L-COG,M-COG,H-COG).After Nrf2 pathway inhibitors were added,HK-2 cells were divided into H-COG group and ML385 group.CCK8 method was used to detect cell activity.Apoptosis was detected by flow cytometry.The expressions of Bcl-2 associated X protein(Bax),B-cell lymphoma/leukemia 2(Bcl-2),activated caspase3(cleaved caspase3),Nrf2/HO-1 pathway protein were detected by Western blot.Reactive oxygen species(ROS)content was detected by DCFH-DA,glutathione peroxi-dase(GSH-Px)activity,superoxide dismutase(SOD)activity,interleukin-6(IL-6)content and tumor necrosis factor α(TNF-α)content were detected by ELISA.Results Compared with control group,the cell activity,Bcl-2 protein expression,GSH-Px and SOD activity in model group were significantly decreased,and the apoptosis rate,Bax,Nrf2,HO-1 and cleaved caspase3 protein expression,ROS,IL-6 and TNF-α content were significantly in-creased(P＜0.05).Compared with model group,the cell activity,Bcl-2 protein expression,GSH-Px and SOD ac-tivity of L-COG,M-COG,and H-COG were significantly increased.Apoptosis rate,Bax,Nrf2,HO-1,cleave-caspase3 protein expression,ROS,IL-6,TNF-α content were significantly decreased(P＜0.05).Compared with H-COG,the cell activity,Bcl-2 protein expression,GSH-Px and SOD activity in ML385 group were significantly increased.The apoptosis rate,Bax and cleaved caspase3 protein expression,ROS,IL-6,TNF-α content were sig-nificantly decreased(P＜0.05).Conclusions The total cornus officinis glucoside may reduce the oxidative stress and inflammatory response of renal tubular epithelial cells induced by high glucose through inhibiting Nrf2/HO-1 pathway and then reduce cell apoptosis.

Clinical data of a teenager with slipped capital femoral epiphysis (SCFE) combined with primary hyperparathyroidism (PHPT) treated in the Children′s Hospital of Soochow University in May 2022 were retrospectively analyzed.A girl, aged 13 years and 5 months, had claudication of both lower limbs for 1.5 years, and the symptom was aggravated for 1 month.X-ray examination of the hip joint showed bilateral SCFE.However, the patient had a body mass index of 18.2 kg/m 2 and no trauma, which did not meet the typical characteristics of SCFE.Further ultrasound examination of the parathyroid gland shows parathyroid adenoma.And parathyroid adenoma was considered to cause PHPT, which in turn triggered SCFE.After surgical resection of the PHPT, the patient had a better fusion of the femoral head and femoral neck and improved hip joint function.Therefore, SCFE fixation was not performed.The diagnosis and treatment of this patient indicated that for similar patients with SCFE and PHPT, SCFE may not be treated with internal fixation, if the femoral head and femoral neck have been fused, the hip joint function has improved, and the pain has been relieved after resection of PHPT.In patients with SCFE and PHPT, the management of hyperparathyroidism takes precedence over the treatment of SCFE.Acute and acute-on-chronic slip, with or without PHPT-induced hypercalcemia, should be treated first by SCFE fixation, and excising parathyroid adenoma should be performed simultaneously or as soon as possible.For chronic slip patients who have mild to moderate hypercalcemia and one or more related symptoms, parathyroidectomy should be performed firstly, and then the SCFE fixation should be considered after parathyroid hormone and blood calcium levels become stable.

Objective To investigate the predictive value of CALLY index for ischemic post-stroke depression(PSD).Methods The clinical data of 179 patients with ischemic stroke were included,and the demographic information,medical history,stroke severity and laboratory indicators at admission were collected.After 6 months of follow-up,all patients were assessed for depressive symptoms using the 17-item Hamilton Depression Scale(HAMD-17).Patients were divided into the PSD group(48 cases)and the non-PSD group(131 cases).Differences in clinical characteristics were compared between the PSD group and the non-PSD group.CALLY index was calculated from C-reactive protein(CRP),albumin(ALB)and lymphocyte counts.Receiver operating characteristic(ROC)curve was used to analyze the predictive value of CALLY index to PSD.Spearman correlation analysis was used for the correlation between CALLY index and neurological and cognitive function in PSD patients.K-M curve and Cox regression were used for analyzing the influence of CALLY index on PSD.Results The CALLY index of 179 patients ranged from 0.54 to 1.79,with a median of 1.08.ROC curve analysis showed that the optimal critical value of CALLY index to predict PSD was 1.09,and the area under ROC curve was 0.757(95%CI:0.687-0.818).Compared with the non-PSD group,the proportion of females was higher in the PSD group,and the proportion of patients with hyperlipidemia was increased with shorter years of education.The serum C-reactive protein(CRP)was higher,and albumin(ALB)and CALLY index were lower(P＜0.05).The K-M curve showed that the incidence of PSD was significantly higher in the low CALLY index group(CALLY≤1.08)than that in the higher CALLY index group(CALLY＞1.08,33.0%vs.20.5%,Log rank χ2=8.553,P=0.004).Cox regression analysis showed that after adjusting for other covariates,the decreased CALLY index was an independent risk factor for PSD(HR=2.651,95%CI:1.269-5.540,P＜0.05).Conclusion CALLY index has a certain predictive value for PSD in acute ischemic stroke patients,which is helpful for early identification and timely intervention to improve the prognosis of patients.

Objective:To evaluate the real-world short-term effectiveness of ixekizumab in the treatment of psoriasis, and to investigate factors influencing the effectiveness.Methods:Baseline data and short-term effectiveness evaluation results were retrospectively collected from patients with psoriasis, who received ixekizumab treatment in Department of Dermatology, Xiangya Hospital from November 2019 to September 2021. A descriptive analysis was performed on the baseline characteristics of patients, continuous data were described as median (lower quartile, upper quartile), and categorical data were described as percentages. Comparisons of disease severity scores before and after the treatment with ixekizumab were performed using Wilcoxon signed-rank test or paired McNemar test. Multivariable logistic regression analysis was conducted to explore factors influencing the effectiveness of 4-week ixekizumab treatment.Results:A total of 118 patients with psoriasis were included, including 94 males and 24 females, and their age [ M ( Q1, Q3) ] was 43.4 (32.5, 53.0) years; plaque psoriasis (99 cases, 83.9%) and severe psoriasis (72 cases, 68.6%) predominated among the 118 patients, and skin lesions were mainly located on the scalp (59/116, 50.9%). Among the 49 patients who had received 2-week ixekizumab treatment, 27 (55.1%) achieved a 50% improvement in the psoriasis area and severity index (PASI) score (PASI50) ; after 4-week treatment, 44 (89.8%), 30 (61.2%), 13 (26.5%) and 10 (20.4%) patients achieved PASI50/75/90/100 respectively, and their PASI scores (2.1 [1.1, 7.1]), involved body surface area (3.9% [0.5%, 14.5%]), dermatology life quality index scores (1.0 [0.0, 2.0]) and physician global assessment (PGA) scores (1.0 [1.0, 3.0]) were significantly lower than the corresponding scores at baseline (12.4 [8.8, 23.2], 22.0% [11.3%, 43.4%], 6.0 [3.0, 11.0], 4.0 [3.0, 5.0], respectively; all P < 0.001]. Multivariable logistic regression analysis showed that the baseline body mass index was significantly associated with the PASI75 response rate ( OR = 0.814, 95% CI: 0.659 - 0.958, P = 0.029) and the proportion of patients with PGA0/1 ( OR = 0.743, 95% CI: 0.562 - 0.917, P = 0.017) after 4-week ixekizumab treatment, and the baseline BSA score was significantly associated with the proportion of patients with PGA0/1 after 4-week ixekizumab treatment ( OR = 0.924, 95% CI: 0.870 - 0.968, P = 0.003) . Conclusion:The 4-week ixekizumab treatment significantly decreased the severity of psoriasis, and may be more effective in patients with lower disease severity and lower body mass index at baseline.

Objective:To evaluate the mid-term results of fenestrated/branched endovascular aortic repair (f/b EVAR) for the treatment of thoracoabdominal aortic aneurysms. M ethods The clinical data of 105 thoracoabdominal aortic aneurysm patients treated with f/b EVAR at the Department of Vascular Surgery of Nanjing Drum Tower Hospital from 2018 to 2019 were retrospectively analyzed. Results:There were 43 cases of thoracoabdominal aortic aneurysm and 62 cases of thoracoabdominal aortic aissection.A total of 336 branch arteries were reconstructed,and technical success rate was 94.3%. 100 cases (95.2%) were followed-up, 6 cases (5.7%) received reoperation interventions, and 11 cases (10.5%) died. During the follow-up period, 69 cases had complete imaging data. Based on the recent CT date of the thoracoabdominal aorta, 58 patients hael positive aortic remodeling and 11 patients hael negative and indeterminate remodeling; there were 31 cases (29.5%) of endoleaks, including 7 cases (6.7%) of type Ⅰb endoleaks, 8 cases (7.6%) of type Ⅱ, 1 case (0.95%) of type Ⅲa, 13 cases (12.4%) of type Ⅲc endoleaks and 2 cases (1.9%) of type Ⅳ. Conclusions:The mid-term follow-up results were satisfactory for TAAA treated with f/b EVAR. Internal leakage remains key point for f/b EVAR.

Cognitive impairment is a common dysfunction after central nervous system disease or injury, which seriously affects the daily life of patients and brings heavy economic burdens to the family and society. Neurofeedback training (NFT) based on electroencephalography (EEG) is a non-invasive method of neuroregulation, which can improve cognitive function and behavior by autonomously adjusting brain function through feedback. This paper reviews the application of EEG signal-based neurofeedback training in cognitive rehabilitation, and discusses the current problems and future development trends in this field, so as to provide new ideas for clinical research and treatment of cognitive disorders.
