Objective To study the effects of embryonic neural stem cells transplantion on trauma of red nucleus neu-rons of the rats with spinal cord injury.Methods NSCs in logarithmic phage were labeled with BrdU,a Sprague Dawley rat mode of spinal cord injury (SCI) was developed with electrocircuit control spinal cord injuring device.Thirty SD rats were randomly divided into three groups: sham group,SCI group and NSC group.The NSCs were trans-planted into injured site three days after SCI.Then NSCs labeled with Brdu were detected by immunohistochemisty,rubrospinal tract (RST) neurons were labeled by retrograde transport of the horseradish peroxidase (HRP) from the lesion site,which were taken by damaged axons and remained in the neurons,then the labeled red nucleus (RN) neurons were counted.Hind limb function of experimental rats was evaluated by a blinder observer using BBB open field locomotion rating score.Results BrdU positive NSCs were detected in the spinal cord after transplantation,the number of RST neurons labeled by HRP in NSC group was more than that in SCI group (P <0.01),the BBB score of NSC group was higher than SCI group (P <0.01).Conclusion The transplanted NSCs can survive in the injured site of spinal cord and protect RN,then promote more remarkably functional recovery after SCI.

Objective To analyze the metabolic profile of children with dyskinetic cerebral palsy by metabolomics, and its abnormal metabolic pathway. Methods The serum of 10 children with dyskinetic cerebral palsy (patient group) and 7 healthy children (control group) aged 6 to 12 years were collected at clinic from May to August, 2014. The serum samples were tested by the nuclear magnetic resonance spectrometer and the spectroscopies were discriminated by partial least squares-discriminant analysis. According to the human metabolome database, the final metabolites disturbed would be figured out. Results 15 chemical shifts were defined, and 6 of them, including 2.04 ppm, 2.12 ppm, 3.00 ppm, 3.24 ppm, 3.76 ppm, 6.50 ppm, were significantly different between 2 groups (P<0.05). The KEGG Pathway Database showed that the levels of taurine, fumarate, oxaloacete, pyruvate, citrate, aspartate, succinate, malate, cysteine decreased, and the levels of glutamate, 2-oxoglutarate, glutamine, leucine, alanine increased. The abnormal metabolism was found in taurine metabolism, glutamine me-tabolism and energy metabolism pathways. Conclusion Based on metabolomics, the metabolic profile of children with dyskinetic cerebral palsy was discriminated out successfully. The further research can focus on the small molecules found out.

Almost all active immunotherapy attempts which targeted at clearing or reducing β-amyloid (Aβ) plaques in brains of patients with Alzheimer'disease (AD) were fallen into unprecedented difficulties,because of unsatisfactory curative effects.Recently,more and more evidences support that low density lipoprotein receptor related protein 1 (LRP1) is involved in Aβ production and clearance through multiple non-immune pathways,which has showed the potential as a whole-new interference target different with classical Aβ immunotherapies.So,we try to summarize the research developments of roles of LRP1 in Aβ metabolic process in physiological and AD conditions,and look forward to its possible applications in the prevention and treatment of AD.

Objective:To analyze the clinical characteristics of domestic sporadic Creutzfeldt-Jakob disease (sCJD).Methods:One patient diagnosed with probable sCJD in our hospital in October 2019 was firstly reported; the clinical data of this patient were retrospectively analyzed combining with those of 82 patients publicly reported in domestic core journals on China Biology Medicine disc, CNKI and WANFANG databases from 2009 to 2019 and met with MRI-CJD consortium criteria for sCJD.Results:Of the total 83 patients, 78 were diagnosed as clinically probable sCJD and other 5 as definite sCJD. There were 45 males and 38 females; the median age was 63 (58, 68) years. The course of disease was recorded in 56 patients, and the time from onset to death was 4.3 (2.9, 7.0) months. The onset and main symptoms were diverse and non-specific, however, progressive cognitive impairments, myoclonus, ataxia, visual dysfunction, akinetic mutism frequently occurred during the whole disease course. As compared with those in patients less than or equal to 65 years old, cerebellar symptoms and visual impairment occurred more frequently in patients over 65 years old ( P< 0.05). High diffusion weighted imaging (DWI) signals were detected on the cortex and/or the basal ganglia and/or the thalamus of 92.4% patients (73/79). Meanwhile, akinetic mutism was more likely to appear in patients with basal ganglia involvements than the unaffected ones (62.5% vs. 25.8%, P<0.05). Abnormal cortical DWI high signals in one patient were detected 7 months before the appearance of first symptom, and four patients who were clinically confirmed by dynamic follow-up DWI presented clinical symptoms highly corresponding to changes in DWI signals in brain regions. Conclusions:The sCJD tends to occur in the middle-aged and elderly patients, with high heterogeneity in clinical symptoms, durations and abnormal DWI signals, and symptoms caused by damage in posterior cranial fossa occur more frequently in patients over 65 years old; the DWI lesions in basal segment might be seen as a sign for deterioration of disease. Dynamic DWI follow-up may be helpful for early detection and objective reflection of sCJD intracerebral lesions.

Objective To evaluate the application and effects of mind map in nursing handover. Methods Two wards which had similar scale, environment, property and level of nursing were randomly chosen as the experimental group and the control group by tossing a coin in Tianjin Hospital of ITCWM Nankai Hospital, 28 nurses were selected in each group, according to the inclusion and exclusion criteria, control group takes routine handover, the experimental group takes handover by following the guidance of mind map. The mind map of clear mind were designned. The Chinese version of Handover Evaluation Scale was used to evaluate the effects of mind map in the nursing handover, the inpatients'satisfaction was compared between the experimental group and the control group after the application of min-d map. Results After3-month intervention, results showed that the score of handover evaluation scale in the experimental group were (31.39 ± 1.34) points, (19.57 ± 1.23) points, (17.61 ± 1.29) points, (68.57 ± 2.49) point, the score of handover evaluation scale in the control group were (26.71±1.24) points,(18.71±1.33) points,(16.68 ± 1.33) points, (62.11 ± 2.94) points, the difference was statistically significant(t=2.504-13.530, P<0.05);in the experimental group, the score of handover evaluation scale increased significantly than that before intervention, and the difference was statistically significant (t=-17.450--5.663, P<0.05);the inpatients′satisfaction in the experimental group was 98.89%(89/90), the control group was 90%(81/90) after intervention, and the difference was statistically significant(χ2=6.776, P<0.05); in the experimental group, the inpatients′satisfaction was better than that before intervention, and the difference was statistically significant (χ2=4.211, P<0.05) .Conclusion:The application of mind map in the n-ursing handover can improve the level of nursing handover and the quality of nursing care, contributing to dveloping high quality of nursing service.

Objective:To investigate risk factors for decompressive craniectomy (DC) after endovascular therapy (EVT) in patients with acute anterior circulation ischemic stroke.Methods:Patients underwent EVT due to acute anterior circulation large vessel occlusion in Liaocheng Brain Hospital from January 2018 to January 2020 were retrospectively included. They were divided into DC group and non-DC group. Univariate and multivariate logistic regression analyses were used to determine risk factors for DC after EVT. Results:A total of 207 patients were enrolled, 126 were male (60.87%), and their age was 66.22±11.24 years old. The baseline National Institutes of Health Stroke Scale (NIHSS) score was 19.84±9.20, and the Alberta Stroke Program Early CT Score (ASPECTS) was 7.98±0.66. The immediate postoperative modified Treatment In Cerebral Ischemia (mTICI) blood flow grade in seven patients (5.80%) was ≤2a, 30 (14.49%) experienced hemorrhagic transformation (HT) after procedure, and 28 (13.5%) received DC. There were statistically significant differences between the DC group and the non-DC group in terms of past stroke history, preoperative NIHSS score and ASPECTS, vascular occlusion site, EVT time, immediate postoperative mTICI ≤2a, and HT (all P<0.05). Multivariate logistic regression analysis showed that atrial fibrillation (odds ratio [ OR] 3.202, 95% confidence interval [ CI] 1.335-9.796; P=0.011), previous stroke history ( OR 2.655, 95% CI 1.016-6.938; P=0.046), high preoperative NIHSS score ( OR 1.074, 95% CI 1.026-1.124; P=0.002), internal carotid artery occlusion ( OR 4.268, 95% CI 1.399-13.024; P=0.011), longer EVT time ( OR 1.010, 95% CI 1.003-1.016; P=0.003), mTICI grade ≤2a ( OR 5.342, 95% CI 1.565-18.227; P=0.007) and postoperative HT ( OR 3.036, 95% CI 1.024-9.004; P=0.045) were independent risk factors for DC. Conclusions:It is not uncommon for patients with acute anterior circulation ischemic stroke to need DC after EVT. Previous stroke history, atrial fibrillation, high baseline NIHSS score, internal carotid artery occlusion, prolonged blood EVT time, mTICI grade ≤2a and postoperative HT are independent predictors of needing DC after EVT.

Objective:To summarize the clinical manifestations, treatment and outcome of neonatal pseudo-Bartter syndrome caused by maternal hyperemesis gravidarum.Methods:This retrospective study collected the clinical data of a set of premature twins with pseudo-Bartter syndrome who were admitted to Hebei Children's Hospital in September 2022. Clinical features of the cases were summarized with descriptive analysis.Results:The twins born with a gestational age of 30 +3 weeks required tracheal intubation and mechanical ventilation due to premature birth and respiratory distress. They were transferred to our hospital 2 h after birth. The mother suffered from hyperemesis gravidarum and even had severe vomiting complicated by hypokalemia 3 d before delivery. The blood gas analysis of the twins at 2 h after birth showed severe metabolic alkalosis, hyponatremia, hypokalemia, hypochloremia and hyperlactatemia. Hyperglycemia appeared at 6 h after birth, and scleredema neonatorum at 24 h after birth. No significant abnormalities were found in the tandem mass spectrometer analysis of blood or urine samples. Whole-exome sequencing showed no abnormalities in the genes related to the phenotype. The twins were diagnosed with neonatal pseudo-Bartter syndrome. After symptomatic and supportive treatment, metabolic alkalosis and electrolyte disorders in the twins were completely resolved 4 d after birth. They were cured and discharged 51 d after birth without recurrence. Follow-up revealed no abnormalities in the physical or neurological development of the twins at 11 months after birth. Conclusions:Maternal hyperemesis gravidarum can lead to neonatal pseudo-Bartter syndrome, characterized by severe metabolic disorders as well as respiratory and circulatory dysfunction at the early stage after birth. Timely diagnosis and treatment are conducive to good prognosis in the affected neonates.

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.

The gene is frequently mutated and abnormally activated in many cancers，and plays an important role in cancer development. Metabolic reprogramming occurs in malignant tumors，which can be one of the key targets for anti-tumor therapy. gene can regulate lipid metabolism through AKT-mTORC1 single axis or multiple pathways，such as lipid synthesis pathways and degradation pathways. Similarly，lipid metabolism can also modify and activate RAS protein and its downstream signaling pathways. This article overviews the current research progress on the interaction between lipid metabolism and ，to provide insight in therapeutic strategies of lipid metabolism for -driven tumors.

Objective:To explores the clinical efficacy and safety of carotid endarterectomy in patients with high bifurcation carotid artery stenosis.Methods:A total of 169 patients with carotid artery stenosis (147 patients with non-high bifurcation carotid artery stenosis and 22 patients with high bifurcation carotid artery stenosis), underwent carotid endarterectomy under surgical microscope in our hospital from January 2017 to January 2020, were included in the study. Patients with high bifurcation carotid artery stenosis were operated by cutting off the posterior abdomen of the digastric muscle to assist in exposing the distal end of the internal carotid artery plaque. Cervical CTA/DSA examination was performed within one week of surgery to confirm whether carotid artery stenosis was relieved; ultrasound examination of cervical vessels was performed 6 months and 1 year after surgery to determine whether restenosis was appeared in the carotid artery. The surgical efficacy, perioperative complications and re-examination results were compared between the two groups.Results:Postoperative carotid artery stenosis was relieved in both groups. The proportions of new cerebral infarction and temporary neurological impairment between the two groups (4.5% vs. 2.0%; 9.1% vs. 3.4%) showed no significant differences ( P>0.05). Carotid artery restenosis was not found in both groups. There was no obvious functional abnormality in the digastric muscles of patients with high bifurcation carotid stenosis. Conclusion:Cutting off the posterior abdomen of the digastric muscle during carotid endarterectomy can better expose the distal end of the internal carotid plaque in patients with high bifurcation carotid stenosis, and provide convenience for effective relief of carotid artery stenosis with high safety.
