Attention-deficit/hyperactivity disorder(ADHD)is a common behavioral disorder in children and has significant non-specific symptoms.The specific pathogenesis of ADHD remains unclear.Chinese medicine has a unique advantage in treating this disease.The"qi cycle in round"theory is a unique diagnosis and treatment system constructed by Huang Yuanyu,a Qing Dynasty physician,through systematic integration and innovative development of the theoretical framework of traditional Chinese medicine,which is widely used in clinical practice.Based on the"qi cycle in round"theory,the pathogenesis of ADHD in children was discussed,and the abnormal middle qi was proposed as the root cause of the disease,with hyperactivity of the liver,lung depletion,and fire as the key contributing factors.Guided by the"qi cycle in round"theory in the treatment of ADHD in children,the approach focuses on restoring and balancing central qi.It emphasized the understanding of the overall changes in the spleen,stomach,lungs,liver,heart,kidney,and other viscera,along with the movement of qi.Treatment focuses on methods such as lifting clear yang,reducing stomach turbidity,softening the liver and quenching the wind,suppressing the lungs and reducing the inversion,and reducing the fire and returning to the yuan.These interventions aim to promote the smooth circulation of the qi circulation from multiple perspectives,thereby facilitating recovery.

Objective:To identify and characterize one Yokenella regensburgei strain(designated as CXLZQ123) isolated from a case of perionychial abscess. Methods:Strain CXLZQ123 was isolated from a patient with periungual abscess at the Dermatology Department of San County Central Hospital in June 2, 2023. The strain was initially identified through morphological and biochemical tests, followed by mass spectrometry identification, 16S rRNA sequencing and whole-genome sequencing. MEGA 11.0 was used to compare and analyze the strain′s genetic relationship with relevant species in GenBank, and a phylogenetic tree was constructed based on genetic distance to analyze its genetic evolution. Meanwhile, the average nucleotide identity between its genome and similar strains were compared.Results:The strain was identified as a Gram-negative rod. MicroScan WalkAway biochemical tests indicated that the strain was either Yokenella regensburgei (91.47%) or Hafnia alvei (8.53%). MALDI-TOF mass spectrometry confirmed it as Yokenella regensburgei. Based on 16S rRNA gene sequence analysis, the strain showed the highest similarity(99.37%) to CIP 105435 (sequence number NR_104934.1). The 16S rRNA gene sequence of the isolated strain Yokenella regensburgei was submitted to the National Center for Biotechnology Information (NCBI) with the GenBank sequence number of OR230248.1. The whole-genome of CXLZQ123 were sequenced and uploaded (NCBI, SRA sequence number: SRR26510420). The average nucleotide identity between CXLZQ123 and Yokenella regensburgei strains W13 and UU2206353 were 98.82% and 99.04%, respectively. Conclusions:Through morphological observation, biochemical identification, mass spectrometry identification, 16S rRNA and whole-genome sequencing, this pathogenic strain is identified as Yokenella regensburgei. This rare bacterium is sensitive to most detected antibiotics. This study provides diagnostic and treatment experience for Yokenella regensburgei-related infections.

ObjectiveTo investigate the expression of lysophosphatidic acid （LPA） in patients with liver cancer， as well as its influence on malignant biological behavior of liver cancer and related regulatory mechanism. MethodsFrom January 2016 to December 2022， 26 patients with liver cancer， 28 patients with liver cirrhosis， and 28 individuals undergoing physical examination were enrolled. ELISIA was used to measure the content of LPA in plasma and peritoneal effusion of the patients with liver cancer or liver cirrhosis accompanied by peritoneal effusion， and the content of LPA was measured in plasma of the normal population at the same time， so as to clarify the difference in the expression of LPA in different populations， such as the patients with liver cancer and those with liver cirrhosis. MTT cell proliferation assay and cell migration assay were used to observe the influence of LPA and its inhibitor pertussis toxin （PTX） on the proliferation， migration， and invasion of SMMC7721 cells. In order to investigate the effect of LPA on the expression of RhoA and its upstream and downstream molecules FAK and P53 after binding to its receptor， qPCR and Western blot were used to observe the effect of LPA on the mRNA and protein expression levels of P53， FAK， and RhoA in SMMC7721 cells. A one-way analysis of variance was used for comparison of the means of continuous data between multiple groups， and the SNK-q test was used for comparison between two groups. ResultsCompared with the patients with liver cirrhosis， the patients with liver cancer had a significantly higher concentration of LPA in plasma （4.99±0.55 μmol/L vs 2.63±0.43 μmol/L， P<0.05） and peritoneal effusion （5.19±0.63 μmol/L vs 2.91±0.46 μmol/L， P<0.05）， and the patients with liver cancer also had a significantly higher level of plasma LPA than the normal population （4.99±0.55 μmol/L vs 1.61±0.39 μmol/L， P<0.05）. The cell proliferation assay showed that LPA significantly promoted the proliferation of SMMC7721 cells， and cell proliferation rate increased with the increase in dose and time； in particular， the middle-and high-dose groups had a significantly higher proliferation rate than the control group （P<0.05）. PTX inhibited the proliferative capacity of SMMC7721 cells in a time-dependent manner， and there was a significant difference between the groups （P<0.05）. The proliferation rate of the 72-hour high-dose LPA group was 3.6 times that of the control group， while the proliferation rate of the PTX group was 0.6 times that of the control group； the proliferation rate of the 72-hour high-dose LPA+PTX group was 1.2 times that of the control group. In addition， LPA increased the migration ability of hepatoma cells， while PTX inhibited their migration， in a time-dependent manner， and there was a significant difference between the groups （P<0.05）. The migration rate of the 72-hour high-dose LPA group was 3.09 times that of the control group， while the migration rate of the PTX group was 0.4 times that of the control group； the migration rate of the 72-hour high-dose LPA+PTX group was 0.99 times that of the control group. qPCR and Western blot showed that there were significant reductions in the mRNA and protein expression levels of P53 in SMMC7721 cells after LPA treatment， while there were significant increases in the mRNA and protein expression levels of FAK and RhoA； there was a significant difference between the LPA group and the control group （P<0.05）. ConclusionThere is an abnormal increase in the expression of LPA in patients with liver cancer， and LPA can promote the proliferation of liver cancer cells and increase their migration ability. At the same time， LPA changes the expression levels of P53， FAK， and RhoA， which may be associated with the promotion of tumor development and progression by LPA.
