In June 1958, the first specialized acupuncture hospital, the Affiliated Acupuncture Experimental Hospital of Jiangsu Provincial School of TCM, was established in Nanjing. This hospital was founded under the initiative of Mr. CHENG Dan'an, the founder of the Chengjiang School of Acupuncture. Centered on clinical acupuncture, the hospital also carried out research and teaching, forming an integrated development model of medical care, education, and research. Its development experience, including a clear hospital-running philosophy, orientation toward solving clinical needs, and deep integration of medical care, education, and research, provides important historical references for the construction of modern specialized acupuncture hospitals.

Working memory is an executive memory process that includes encoding, maintenance, and retrieval. These processes can be modulated by transcranial alternating current stimulation (tACS) with sinusoidal waves. However, little is known about the impact of the rate of current change on working memory. In this study, we aimed to investigate the effects of two types of tACS with different rates of current change on working memory performance and brain activity. We applied a randomized, single-blind design and divided 81 young participants who received triangular wave tACS, sinusoidal wave tACS, or sham stimulation into three groups. Participants performed n-back tasks, and electroencephalograms were recorded before, during, and after active or sham stimulation. Compared to the baseline, working memory performance (accuracy and response time) improved after stimulation under all stimulation conditions. According to drift-diffusion model analysis, triangular wave tACS significantly increased the efficiency of non-target information processing. In addition, compared with sham conditions, triangular wave tACS reduced alpha power oscillations in the occipital lobe throughout the encoding period, while sinusoidal wave tACS increased theta power in the central frontal region only during the later encoding period. The brain network connectivity results showed that triangular wave tACS improved the clustering coefficient, local efficiency, and node degree intensity in the early encoding stage, and these parameters were positively correlated with the non-target drift rate and decision starting point. Our findings on how tACS modulates working memory indicate that triangular wave tACS significantly enhances brain network connectivity during the early encoding stage, demonstrating an improvement in the efficiency of working memory processing. In contrast, sinusoidal wave tACS increased the theta power during the later encoding stage, suggesting its potential critical role in late-stage information processing. These findings provide valuable insights into the potential mechanisms by which tACS modulates working memory.

Conclusion The B. animalis B4 has good probiotic properties, showing excellent safety at the genetic level, with a probiotic gene sequence.

Lung cancer is one of the top 10 causes of death in the world today,and it is a great concern worldwide for its high mortality rate.Currently,the researchers are digging into various factors influencing the occurrence and develop-ment of lung cancer in order to increase the odds for curing lung cancer,improve the prognosis of lung cancer patients as well as reduce its morbidity.The Mediterranean diet(MD)is a special dietary structure that is based on eating vegetables,fruits,coarse grains,legumes and low-fat fish,which have anti-inflammatory,antioxidant and lipid-lowering effects.Recent studies have revealed that the MD may prevent lung cancer occurrence to some extent and inhibit its development.The purpose of this paper is to summarize and analytically discuss the effects of the MD on the oncogenesis and development of lung cancer through a review of the relevant literatures,thus to provide references for MD to prevent and treat lung cancer.

Objective:To analyze the clinical phenotype and genetic characteristics for a child with Canavan disease.Methods:A child who was admitted to the Children's Hospital Affiliated to Shandong University on April 9, 2021 for inability to uphold his head for 2 months and increased muscle tone for one week was subjected to whole exome sequencing, and candidate variants were verified by Sanger sequencing.Results:Genetic testing revealed that the child has harbored compound heterozygous variants of the ASPA gene, including a paternally derived c. 556_559dupGTTC (p. L187Rfs*5) and a maternally derived c.919delA (p. S307Vfs*24). Based on the guidelines from the American College of Medical Genetics and Genomics, both variants were predicted to be pathogenic (PVS1+ PM2_Supporting+ PM3). Conclusion:The c. 556_559dupGTTC (p.L187Rfs*5) and c. 919delA (p.S307Vfs*24) compound heterozygous variants of the ASPA gene probably underlay the pathogenesis of Canavan disease in this child.

Objective To investigate the progression of breast cancer in mice induced by chronic binding stress and the regulatory mechanism of Xiaoyao SAN based on TGF-β1/CD147 signal pathway.Methods 40 BABL/c mice were randomly divided into tumor group,model group,Xiaoyaosan group and Mifepristone group,and then 4T1 cell line was inoculated into the armpits of each group of mice.After Tumor formation,mice in all groups except tumor group were subjected to chronic restraint stress for 21 days.Meanwhile,mice in Xiaoyaosan and Mifepristone groups were gavaged with the corresponding drugs,and mice in the other two groups were gavaged with normal saline.After the modeling,the mice were sacrificed after anaesthesia.The weight and volume of the tumors and visceral index of the mice were measured.The contents of serum tumor markers(CA199,CEA,VEGF),serum neurotransmitters(DA and CORT),and inflammatory mediators(TGF-β1 and IL-10)in tumor tissues were detected by Elisa.The expressions of iNOS and Arg-1,the polarization markers of macrophages,and the expressions of CD147 and its downstream signaling molecules MMP2,MMP9 and VEGF in tumor tissues were all detected by immunohistochemistry and Western blot.Results Compared with tumor group,in model group,tumor weight and volume,serum CA199,CEA,VEGF,CORT content,tumor TGF-β1 and IL-10 content were significantly increased;visceral index and serum DA content were significantly reduced;the expression of M2-type polarization marker Arg-1 in tumor macrophages was significantly increased,while the expression of M1-type polarization marker iNOS was significantly decreased;the expressions of CD147 and its downstream signaling molecules MMP2,MMP9 and VEGF were significantly increased.Both Xiaoyaosan and mifepristone could effectively reverse the above changes.Conclusion The mechanism of chronic restraint stress promoting breast cancer progression in mice is related to the increased release of TGF-β1 from M2-type polarization of tumor-associated macrophages,which activates CD147 and its downstream related signals.Xiaoyaosan could relieve the M2-type polarization of macrophages caused by increased corticosterone under stress conditions,reduce the production of TGF-β1,inhibit CD147 and its downstream signal,and thus inhibit the progression of breast cancer caused by chronic restraint stress in mice.

Currently, there are limited strategies for convenient and rapid wound repair in clinical practice. In recent years, in-situ cell electrospinning (IS-CE) technology, developed from in-situ electrospinning (IS-E) technology, has emerged. IS-CE technology involves encapsulating living cells within micro-nanofibers to construct living fibrous tissue scaffolds in situ, making some progress in wound repair applications. However, this technology still faces limitations such as low cell survival rate and poor fiber stability. This article provides a comprehensive review on the current status of both IS-E and IS-CE technologies, as well as the application of IS-CE technology in wound repair. In addition, the advantages, limitations, and improvement methods of IS-CE technology applied in wound treatment are emphatically discussed, aiming to provide insights for its application in tissue engineering and wound repair.
