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.
3.Empathy for Distress in Humans and Rodents.
Neuroscience Bulletin 2018;34(1):216-236
Empathy is traditionally thought to be a unique ability of humans to feel, understand, and share the emotional state of others. However, the notion has been greatly challenged by the emerging discoveries of empathy for pain or distress in rodents. Because empathy is believed to be fundamental to the formation of prosocial, altruistic, and even moral behaviors in social animals and humans, studies associated with decoding the neural circuits and unraveling the underlying molecular and neural mechanisms of empathy for pain or distress in rodents would be very important and encouraging. In this review, the author set out to outline and update the concept of empathy from the evolutionary point of view, and introduce up-to-date advances in the study of empathy and its neural correlates in both humans and rodents. Finally, the author highlights the perspectives and challenges for the further use of rodent models in the study of empathy for pain or distress.

4.Spinal processing of bee venom-induced pain and hyperalgesia.
Acta Physiologica Sinica 2008;60(5):645-652
Subcutaneous injection of bee venom causes long-term neural activation and hypersensitization in the dorsal horn of the spinal cord, which contributes to the development and maintenance of various pain-related behaviors. The unique behavioral 'phenotypes' of nociception and hypersensitivity identified in the rodent bee venom test are believed to reflect a complex pathological state of inflammatory pain and might be appropriate to the study of phenotype-based mechanisms of pain and hyperalgesia. In this review, the spinal processing of the bee venom-induced different 'phenotypes' of pain and hyperalgesia will be described. The accumulative electrophysiological, pharmacological, and behavioral data strongly suggest that different 'phenotypes' of pain and hyperalgesia are mediated by different spinal signaling pathways. Unraveling the phenotype-based mechanisms of pain might be useful in development of novel therapeutic drugs against complex clinic pathological pain.

The data of a child with sphingosine phosphate lyase insufficiency syndrome (SPLIS) admitted to Children′s Hospital of Hebei Province on February 4, 2020 were retrospectively analyzed.The child had edema, complicated with ichthyosis, adrenal calcification, and hearing loss from the early infancy.Laboratory examination results suggested a low albumin level, hypercholesterolemia, a high proteinuria level, abnormal liver and renal functions, and hyponatremia.The child gave up treatment and died at home.Whole Exome Sequencing (WES) results showed two hete-rozygous mutations of SGPL1 gene (chr10: 72604336, c.134G>A, p.W45X; chr10: 72629563, c.719G>T, p.S240I). SPLIS is inherited in an autosomal recessive manner.It starts in infancy, and affects the kidney, skin, endocrine, nervous and immune systems.It is suggested that SPLIS patients should take genetic examination.Early diagnosis, appropriate intervention, and vitamin B 6 treatment may relieve some symptoms of SPLIS patients.Adeno-associated virus mediated SGPL1 gene replacement therapy can be a novel cure of SPLIS and is worthy of investigation.

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.

Objective:To analyze and summarize the efficacy and safety of thalidomide in the treatment of refractory systemic juvenile idiopathic arthritis(sJIA).Methods:The clinical data of ten patients with refractory sJIA admitted to Department of Nephrology and Immunology in Children's Hospital of Hebei Province from January 2015 to March 2022 were collected,and the clinical manifestations,efficacy and safety of thalidomide in the treatment of refractory sJIA were analyzed retrospectively. Systemic juvenile arthritis disease activity score(sJADAS)was used to evaluate the efficacy of the treatment. Statistical analysis was performed by repeated measurements using general linear models.Results:Among the 10 children(4 males and 6 females)with refractory sJIA,the average age of onset was(7.5±3.3)years. Seven patients were complicated with macrophage activation syndrome at an early stage of disease.The average course of disease was(4.4±1.7)years,and the longest course of disease was 8.3 years. Before the application of thalidomide,all the 10 children experienced relapses(ranging from 2 to 10 times). The indices of 10 children treated with thalidomide at 6 months and 12 months were compared with those before treatment. Peripheral blood leukocytes[(10.19±3.67)×10 9/L,(8.53±2.83)×10 9/L vs.(16.11±7.81)×10 9/L, F=7.918,11.084, P=0.020,0.009],C-reactive protein[19.13(0.38,35.21)mg/L,8.05(0.10,18.00)mg/L vs. 59.34(24.20,131.90)mg/L, F=7.030,12.731, P=0.026,0.006],sJADAS scores[6.00(1.50,12.50)scores,3.00(0,12.50)scores vs. 20.00(11.50,28.00)scores, F=14.710,17.870, P=0.004,0.002]were decreased significantly. The doses of prednisone[0.13(0,0.45)mg/(kg·d),0.02(0,0.06)mg/(kg·d)vs. 0.42(0.16,1.47)mg/(kg·d), F=5.890,7.623, P=0.041,0.022]were significantly decreased.All the differences were statistically significant. Prednisone was successfully discontinued in 7 cases. Tocilizumab was gradually withdrawn in 3 cases,and tocilizumab administration interval was prolonged in 1 case. None of the 10 children had serious adverse reactions. Conclusion:Thalidomide is clinically effective in the treatment of sJIA,and can reduce the required dose of prednisone and prolong the tocilizumab free remission.
