Relationships between the Extratropical ENSO Precursor and Leading Modes of Atmospheric Variability in the Southern Hemisphere

Previous studies suggest that the atmospheric precursor of E1 Nifio-Southern Oscillation （ENSO） in the extratropical Southern Hemisphere （SH） might trigger a quadrapole sea surface temperature anomaly （SSTA） in the South Pacific and subsequently influence the following ENSO. Such a quadrapole SSTA is referred to as the South Pacific quadrapole （SPQ）. The present study investigated the relationships between the atmospheric precursor signal of ENSO and leading modes of atmospheric variability in the extratropical SH [including the SH annular mode （SAM）, the first Pacific-South America （PSA1） mode, and the second Pacific-South America （PSA2） mode]. The results showed that the atmospheric precursor signal in the extratropical SH basically exhibits a barotropic wavenumber-3 structure over the South Pacific and is significantly correlated with the SAM and the PSA2 mode during austral summer. Nevertheless, only the PSA2 mode was found to be a precursor for the following ENSO. It leads the SPQ-like SSTA by around one month, while the SAM and the PSA1 mode do not show any obvious linkage with either ENSO or the SPQ. This suggests that the PSA2 mode may provide a bridge between the preceding circulation anomalies over the extratropical SH and the following ENSO through the SPQ-like SSTA.

Effect of rehabilitation training combined with hyperbaric oxygen therapy on the nerve cytokine secretion and oxidative stress in rehabilitation period of patients with cerebral infarction

Objective: To discuss the influence of rehabilitation training combined with hyperbaric oxygen therapy on the nerve cytokine secretion and oxidative stress in rehabilitation period of patients with cerebral infarction. Methods: A total of 110 patients with cerebral infarction who received rehabilitation therapy in the hospital between January 2015 and May 2017 were divided into routine group (n=55) and hyperbaric oxygen group (n=55) according to random number table. Routine group received regular rehabilitation training, and hyperbaric oxygen group underwent rehabilitation training combined with hyperbaric oxygen therapy. The differences in the serum contents of nerve factors, neurotransmitters and oxidative stress indexes were compared between the two groups at immediately after admission (T0) and after 14 d of treatment (T1). Results: At T0, there was no statistically significant difference in the serum contents of nerve factors, neurotransmitters and oxidative stress indexes between the two groups. At T1, serum nerve factors MBP and NSE contents of hyperbaric oxygen group were lower than those of routine group while NGF content was higher than that of routine group;serum neurotransmitter Glu content was lower than that of routine group while GABA content was higher than that of routine group;serum oxidative stress indexes ROS and LHP contents were lower than those of routine group while CAT and SOD contents were higher than those of routine group. Conclusion: Rehabilitation training combined with hyperbaric oxygen therapy can effectively optimize the nerve function and inhibit the systemic oxidative stress response in rehabilitation period of patients with cerebral infarction.

TET1 Participates in Complete Freund’s Adjuvant-induced Trigeminal Inflammatory Pain by Regulating Kv7.2 in a Mouse Model

Trigeminal inflammatory pain is one of the most severe pain-related disorders in humans;however,the underlying mechanisms remain largely unknown.In this study,we investigated the possible contribution of interaction between ten-eleven translocation methylcytosine dioxygenase 1(TET1)and the voltage-gated K^(+)channel Kv7.2(encoded by Kcnq2)to orofacial inflammatory pain in mice.We found that complete Freund’s adjuvant(CFA)injection reduced the expression of Kcnq2/Kv7.2 in the trigeminal ganglion(TG)and induced orofacial inflammatory pain.The involvement of Kv7.2 in CFA-induced orofacial pain was further confirmed by Kv7.2 knockdown or overexpression.Moreover,TET1 knockdown in Tet1^(flox/flox)mice significantly reduced the expression of Kv7.2 and M currents in the TG and led to pain-like behaviors.Conversely,TET1 overexpression by lentivirus rescued the CFA-induced decreases of Kcnq2 and M currents and alleviated mechanical allodynia.Our data suggest that TET1 is implicated in CFA-induced trigeminal inflammatory pain by positively regulating Kv7.2 in TG neurons.

Exome sequencing reveals genetic architecture in patients with isolated or syndromic short stature

Short stature is among the most common endocrinological disease phenotypes of childhood and may occur as an isolated finding or in conjunction with other clinical manifestations.Although the diagnostic utility of clinical genetic testing in short stature has been implicated,the genetic architecture and the utility of genomic studies such as exome sequencing(ES)in a sizable cohort of patients with short stature have not been investigated systematically.In this study,we recruited 561 individuals with short stature from two centers in China during a 4-year period.We performed ES for all patients and available parents.All patients were retrospectively divided into two groups:an isolated short stature group(group I,n=257)and an apparently syndromic short stature group(group II,n=304).Causal variants were identified in 135 of 561(24.1%)patients.In group I,29 of 257(11.3%)of the patients were solved by variants in 24 genes.In group II,106 of 304(34.9%)patients were solved by variants in 57 genes.Genes involved in fundamental cellularprocess played an important role in the genetic architecture of syndromic short stature.Distinct genetic architectures and pathophysiological processes underlie isolated and syndromic short stature.

The identification of PAX7 variants and a potential role of muscle development dysfunction in congenital scoliosis

Dear Editor,Congenital scoliosis(CS)is a spinal malformation charac-terized by failure of vertebral formation or segmentation,or a mix of these deformities,resulting in longitudinal and rotational imbalance,and affects 0.05-0.1%of new-borns(Wu et al.2015).It is generally understood that the development of CS has an underlying genetic basis.Specifically,genes related to somite regulation or osteo-genesis during embryonic development are believed to be responsible for the vertebral malformations observed in CS patients(Pourquie 2011).

Mutational spectrum of syndromic genes in sporadic brain arteriovenous malformation

Background:Brain arteriovenous malformations(BAVMs)are abnormal vessels that are apt to rupture,causing lifethreatening intracranial hemorrhage(ICH).The estimated prevalence of BAVMs is 0.05%among otherwise healthy individuals.In this study,we aim to investigate the mutational spectrum of syndromic genes in sporadic BAVM.Methods:We recruited a cohort of 150 patients with BAVM and performed whole-exome sequencing on their peripheral blood DNA.To explore the mutational spectrum of syndromic genes in sporadic brain arteriovenous malformation,we selected six genes according to the Online Mendelian Inheritance in Man(OMIM)and literature.All variants in the six candidate genes were extracted and underwent filtering for qualifying variants.Results:There are a total of four patients with rare variants in hereditary hemorrhagic telangiectasia-related genes.In addition,we identified two patients have the variant of RASA1 gene in our database,which are also rare mutations that are absent from population databases.However,we did not find any patients with GNAQ mutations in our database.Conclusions:In conclusion,we demonstrated that variants in syndromic vascular malformations play important roles in the etiology of sporadic BAVM.

Advances in clinical genetics and genomics

Developments in genetics and genomics are progressing at an unprecedented speed.Twenty years ago,the human genome project provided the first glimpses into the human genome sequence and launched a new era of human genetics.The emerging of next-generation sequencing(NGS)in 2005 then made possible comprehensive genetic testing such as exome sequencing and genome sequencing.Meanwhile,great efforts have been put into the optimization of bioinformatic pipelines to make increasingly speedy and accurate variant analyses based on NGS data.These advances in sequencing technologies and analytical methods have revolutionized the diagnostic odyssey of suspected hereditary diseases.More recently,the genotype-phenotype relationship and polygenic risk scores(PRSs)generated from genome-wide association studies have expanded our horizon from rare genetic mutations to a genomic landscape implicated by the combined effect of both rare variants and polymorphisms.At the same time,clinicians and genetic counselors are facing huge challenges conferred by overwhelming genomic knowledge and long sheets of testing reports for comprehensive genomic sequencing.The path toward the“next-generation”clinical genetics and genomics may underlie semiautomatic pipelines assisted by artificial intelligence techniques.
