Objective To compare the efficacy of adrenocorticotrophic hormone (ACTH) and methylprednisolone on the rat models of infantile spasms (IS).Methods The SD rats on postnatal 10 day (P10) were divided into blank group (n =18),control group (n =18) and model group (n =110) according to the random number table method.The rats of model group were prepared by adopting prenatal stress exposure and N-methyl-D aspartate (NMDA) injection.In the model group,after inducing epileptic seizures,the rats were divided into different groups (18 rats in each group) according to the random number table method as following:model group Ⅰ (subcutaneous injection ofACTH,50 IU/kg,at P10:14:00,21:00;P11,P12:7:00,14:00,21:00;P13:7:00),model group Ⅱ (subcutaneous injection of 9 g/L saline),model group Ⅲ (intraperitoneal injection of methylprednisolone,60 mg/kg,at P11,P12,P13:9:00,once per day),model group Ⅳ (intraperitoneal injection of 9 g/L saline) and model group Ⅴ (positive control group,with no drug or saline injection).Three days later,epilepsy was induced again,and the rats of model group were intraperitoneally injected with NMDA (12 mg/kg) at P13 (10:00).The rats of control group were injected intraperitoneally with same volume of 9 g/L saline,but the rats of blank group were not treated.Behaviors of rats with epilepsy seizures were observed and epilepsy scores were given.The expression of corticotropin-releasing hormone (CRH) in the hypothalamus of each group was detected by using immunohistochemistry and fluorescence quantitative polymerase chain reaction.The learning and memorizing capacity of the rats were measured by Y-maze experiment.Results There was no death in the model group after the onset of seizure.In the model group Ⅰ,13 cases were attacked(72.22％),and 14 cases were attacked in the model group Ⅲ (78.78％).The level of attack was decreased.The buckling state was not observed in model group and Ⅲ,but the latency period of epilepsy was prolonged and the epilepsy scores were significantly decreased.There were no significant differences of onset latency [(2 369.38 ± 628.70) s vs.(1 922.93 ± 462.36) s] and epilepsy score [(2.15 ± 1.14) scores vs.(2.07 ± 0.83) scores] between the 2 groups (all P ＞ 0.005).The rats of model group Ⅱ,Ⅳ,Ⅴ were all attacked completely and presented buckling state.There was no onset or death in blank group and control group.The number of CRH positive cells and CRH mRNA relative expression of each model group were higher than those in the blank group and control group.The number of CRH positive cells and CRH mRNA expression of model group Ⅰ and Ⅲ were lower than those in model group Ⅱ,Ⅳand Ⅴ,and the differences were significant (all P ＜ 0.002 4).There was no significant difference in the number of CRH-positive cells(39.12 ± 5.98 vs.41.48 ± 7.61) and CRH mRNA relative expression (1.92 ± 0.16 vs.2.06 ± 0.39) between model group Ⅰ and Ⅲ (all P ＞ 0.002 4).No significant difference was found between blank group and control group,or among model group Ⅱ,Ⅳ and Ⅴ (all P ＞ 0.002 4).There were no significant differences in the learning capacity among all groups (F =2.196,P ＞ 0.002 4).The correct response rate after 24 hours of the model group was lower than the blank group and control group,and ACTH and methylprednisolone pretreatment did not influence the memorizing capacity (P ＞ 0.002 4).Conclusion The effect of pretreatment of ACTH is similar to that of methylprednisolone in the rat model of IS.

Increased glycolysis is a major feature of metabolic reprogramming in cancer.Glycolysis provides not only energy for cancer cells but also necessary precursors for biosynthesis, which is important for promoting tumor growth.Cancer cells meet their own needs by regulating glycolytic enzymes, which play an active role in promoting cancer survival, metastasis, and invasion.Lactate dehydrogenase (LDH), as a key enzyme in glycolysis, consists of two subunits: lactate dehydrogenase A (LDHA) and lactate dehydrogenase B (LDHB).LDHA is known to play a key role in aerobic glycolysis and has been extensively studied, whereas less has been done on LDHB.However, at present, more and more reports have revealed the important effects of LDHB on the progression of various cancers.A large number of studies have shown that LDHB is abnormally expressed in a variety of cancers, which is related to the malignant progression of tumors.The article reviews the research progress of LDHB in recent ten years, including its regulatory mechanism in tumor, its relationship with cancer development and its role as a biomarker in clinical diagnosis of cancer, which provides some insight for further investigation of the mechanism of LDHB in cancer research.

OBJECTIVE: To explore the genetic basis for three children with Menkes disease. METHODS: The patients were subjected to next-generation sequencing (NGS) to detect potential variants of the ATP7A gene. Suspected variants were verified by Sanger sequencing of their family members and 200 healthy individuals. Multiplex ligation-dependent probe amplification (MLPA) was also carried out to detect potential deletions in their family members and 20 healthy individuals. RESULTS: Variants of the ATP7A gene were detected in all of the three families, including a novel c.1465A>T nonsense variant in family 1, a novel c.3039_3043del frame-shifting variant in family 2, and deletion of exons 3 to 23 in family 3, which was reported previously. Based on the standards and guidelines of American College of Medical Genetics and Genomics, the c.1465A>T and c.3039_3043del variants of ATP7A gene were predicted to be likely pathogenic (PVS1+PM2). CONCLUSION Variants of the ATP7A gene may underlay the Menkes disease in the three children. Above findings have facilitated clinical diagnosis and enriched the spectrum of genetic variants of Menkes disease.

Objective: To explore the relationship between different mutation characteristics and clinical phenotype of children with Dravet syndrome (DS) with SCN1A gene mutation, and to summarize the drug efficacy. Methods: The clinical data of children diagnosed as DS from the Department of Pediatrics Neurology, the Third Affi-liated Hospital of Zhengzhou University from January 2014 to May 2018 were collected.The peripheral blood DNA of the children was detected by adopting next generation sequencing for epilepsy-related gene-panel, while the parents′ were screened by using Sanger sequencing for family verification.Multiple ligation-dependent probe amplification technology was used to detect large fragment variation of SCN1A gene if the mutations of the children were negative.The Gesell scale and cavity Wechsler intelligence scale for children(C-WISC) were used to evaluate the intelligence of children. Results: A total of 50 cases of DS were collected, 38 cases of them were positive for SCN1A mutation, and the mutation rate was 76.0%(38/50 cases), of which, the missense mutation[50.0%(19/38 cases)] and frameshift mutation[28.9%(11/38 cases)] were dominant.The average onset age of 50 patients was 6 months, of which onset of seizures was triggered by fever(temperature>37.5 ℃) in 68.0%(34/50 cases)of children, the history of seizures in hot baths was found in 60.0%(30/50 cases) of children, status epilepticus was found in 74.0%(37/50 cases), cluster-like episodes was found in 80.0%(40/50 cases), ≥2 seizure types was found in 92.0%(46/50 cases). Mental retarda-tion was found in most of the children, of which 30.0% (15/50 cases) were mild mental retardation, 38.0% (19/50 cases) were moderate mental retardation, 14.0% (7/50 cases)were severe intelligence retardation.Interictal abnormalities of electroencephalogram(EEG) before 1 year old was found in 24.0%(12/50 cases), and the average age of EEG abnormalities was 30.12 months old; the top three drug efficacy rates were 70.0% (28/40 cases) of Topiramate, 48.0% (24/50 cases) of Sodium Valproate, 45.7% (16/35 cases) Clonazepam or Clobazam.The time of onset of myoclonus and atypical absence of the truncation mutation group was earlier than that of the missense mutation group(14.75 months vs.21.20 months; 16.82 months vs.26.00 months), and the difference was statistically significant(P<0.05). The proportion of clustered episodes in the truncation mutation group was higher than that in the missense mutation group [94.7%(18/19 cases)vs.63.2%(12/19 cases)], and the difference was statistically significant (P<0.05). There was no significant correlation between the SCN1A gene mutation (type and position) and age of onset, type of seizure, proportion of convulsion persistence, the mental development or abnormal proportion of EEG and seizure frequency before 1 year old(all P>0.05). Conclusions The SCN1A gene mutation rate is high in children with DS, and the SCN1A gene mutation characteristics has a certain correlation with DS clinical phenotype.Topiramate is the most effective drug among children with DS.

Objective:To explore the clinical manifestations and genetic characteristics of Wolf-Hirschhorn syndrome (WHS) to improve the ability of diagnosis and differential diagnosis of the disease.Methods:The clinical features and auxiliary examinations and treatment of a proband with WHS caused by microdeletion of 4p16.3 segment who admitted to the Third Affiliated Hospital of Zhengzhou University in December 2021 were recorded, and whole exome sequencing (WES) of the family was performed. The prognosis was followed up.Results:The female proband, 11 months old, presented with convulsions at the age of 8 months, with the characteristics of heat sensitivity and cluster seizures, and her identical twin sister had a similar medical history. Physical examination found malnutrition, retarded development, special face, prominent forehead, wide nasal bridge, small jaw, precordial murmur and grade 3/6 murmur in the whole period, hyperactivity of P2, and low limb muscle tone. The whole exon and copy number variation (CNV) test of the family revealed that the proband had a 1.99 Mb heterozygous deletion in the chromosome 4p16.3 segment, including WHSC1 (NSD2), WHSC2 (NEFLA) and other genes. Copy number variation sequencing (CNV-Seq) of the proband and her sister showed 1.97 and 1.92 Mb heterozygous deletion of chromosome 4p16.3, respectively. Genealogical analysis by quantitative polymerase chain reaction revealed that the CNV was de novo, and it was determined to be a pathogenic variant according to the American College of Medical Genetics and Genomics guidelines. The proband took sodium valproate orally, and her sister took oral sodium valproate, zonisamide, and levetiracetam successively, and at the same time they received family rehabilitation training. The age at the last follow-up was 1 year and 8 months. Neither of them had convulsions again in the past 3 months, but the developmental delay was obvious. Conclusion:WHS patients may present with growth retardation, epilepsy, Greek warrior helmet-like special face, and congenital heart disease, and may have microdeletions in the chromosome 4p16.3 segment.

Percutaneous nephrolithotripsy is the first line treatment for complete staghorn calculi, but there are risks such as renal function damage, bleeding, and infection. A case of complete staghorn calculi 8.3 cm×4.5 cm and mean CT value of 1 321 HU was reported. Urine culture suggested proteus mirabilis infection. The patient was given sensitive antibiotics for 3 days, and was treated with one session of natural orifice transluminal endoscopic lithotripsy with intelligent control of renal pelvic pressure. KUB on the first postoperative day showed residual stones of 1.0 cm×0.5 cm. There were no complications.
