The key to the onset and progression of the functional impairments of orthopedic diseases is imba-lance of deficiency and excess， disharmony of movement and stillness， dislocation of sinews and bones， imbalance of rigidity and flexibility， and disharmony of body and spirit. Based on this， the "five views" treatment principle has been proposed for traditional Chinese medicine （TCM） orthopedic rehabilitation， which include the view of balancing deficiency and excess， combining movement and stillness， focusing on both sinews and bones， integrating rigidity and flexibility， and harmonizing body and spirit. Correspondingly， the "five views" collaborative rehabilitation clinical model is established， providing a reference for enhancing the systematization and targeting of TCM orthopedic rehabilitation.

Curzerene, a sesquiterpene compound isolated from Curcuma Radix, exhibits various therapeutic effects, such as anti-tumor and anti-hyperlipidemic properties. However, its neuroprotective effects have not yet been reported. This study focused on exploring the neuroprotective effect of curzerene and elucidating its potential mechanism by combining molecular biotechnology with multi-omics approaches. Curzerene was orally administered to LPS-induced depressive-like behaviors and cognitive impairment in mice for 14 days, and the related biochemical parameters were evaluated. The possible mechanisms were elucidated using qRT-PCR, Western Blot, immunofluorescence, untargeted metabolomics, GC-MS and 16S rDNA comprehensively. Curzerene ameliorated depression symptoms and cognitive impairment by increasing the preference for sucrose in SPT and the central area and total distance traveled in OFT, reducing the immobility time in TST and FST, as well as rising the spontaneous alternation ratio in Y maze. Multiple molecular biology techniques analyses indicated the ameliorative effect of curzerene via HMGB1/RAGE/ TLR4 pathway. Moreover, curzerene primarily regulates purine metabolism, phenylalanine, tyrosine and tryptophan biosynthesis, phenylalanine metabolism, pyrimidine metabolism, etc. Furthermore, intervention increased the relative abundance of Parabacteroides, Clostridia_UCG-014_unclassified, and Rhodospirillales_unclassified, and enhanced the production of SCFAs. This work demonstrated that curzerene effectively protects against LPS-induced neurological damage, potentially by inhibiting the HMGB1/ RAGE/TLR4 pathway through the restoration of gut microbiota homeostasis, modulation of metabolites, and enhancement of SCFAs. In conclusion, this study offers new perspectives on the therapeutic possibilities of curzerene in mitigating depressive-like behaviors and cognitive impairment.

Pinellia ternata， belonging to the Pinellia genus within the Araceae family， is a medicinal plant due to its tubers. There are severe issues with unclear germplasm and mixed varieties in its cultivation， necessitating urgent new variety protection efforts. The distinctness， uniformity， and stability （DUS） testing of the plant variety is the basis for protecting new plant varieties， and the DUS test guidelines are the technical basis for DUS testing. To develop the DUS test guidelines for P. ternata， agronomic traits of 229 germplasm of P. ternata were observed and measured during its two growth stages over the years， and each character was graded and described. A total of 38 traits were selected as the test traits of the DUS test guideline for P. ternata. There were three plant traits， 19 leaf traits， six flower traits， two fruit traits， two tuber traits， five bulbil traits， and one ploidy trait. These traits could be divided into 22 quality characters， 12 quantitative characters， and four pseudo-quantitative characters， as well as seven groups， including plants， leaves， flowers， fruit， tubers， bulbils， and ploidy. By searching for standard traits， 10 standard varieties were ultimately determined. Preparing these guidelines will have great significance for reviewing and protecting P. ternata varieties， safeguarding breeders' rights， and promoting the development of the P. ternata industry.

Hepatocellular carcinoma(HCC),as the most common type of liver cancer,poses a significant threat to global public health due to its high incidence and mortality rates.This paper delves into the etiology,pathogenesis,and syndrome differentiation of liver cancer from the perspective of"dispersing qi and fortifying the body resistance",based on the clinical experience of renowned traditional Chinese medicine(TCM)practitioner,Prof.Changquan Ling.Prof.Ling believes that the development of liver cancer is closely related to the disruption of liver qi flow,the accumulation of blood stasis over time,and the generation of toxin from long-term stagnation,accompanied by pathological changes such as imbalance of yin and yang,deficiency of the body's vital qi and accumulation of pathogenic factors,and internal blazing of cancer toxins.In terms of treatment,he emphasizes the principles of dispersing qi and fortifying the body resistance,addressing both the root cause and symptoms.This is achieved by regulating the functions of viscera,improving the stagnation of qi flow,and supplemented by methods such as clearing heat and detoxifying,and softening and dispersing hard masses,aiming to break the vicious cycle of qi stagnation,deficiency of vital qi,and pathogenic factor generation,thereby promoting the recovery from the disease.Through detailed analysis of clinical cases,this paper demonstrates Prof.Ling's unique insights and significant efficacy in treating liver cancer through"dispersing qi"to"fortify the body resistance",ultimately achieving"tumor suppression".This provides new references and perspectives for the clinical diagnosis and treatment of liver cancer in TCM.

AIM:To investigate the expression profile and biological significance of long noncoding RNA(lncRNA)zinc finger antisense 1(ZFAS1)in the brains of mice with diabetic encephalopathy(DE).METHODS:Ten db/m mice served as the normal control group,while twenty 22-week-old db/db mice were used to establish the DE model and randomly divided into two subgroups:ten as the db/db model control and the remaining ten receiving ZFAS1 gene knockdown(db/db+sh-ZFAS1)via lentiviral transfection.Weekly measurements of body weight and blood glucose levels were performed.Brain tissues were collected for Nissl staining to evaluate neuronal damage,TUNEL assay to detect apop-tosis,and immunofluorescence staining to examine neural biomarker expression.Serum levels of tumor necrosis factor-α(TNF-α)and oxidative stress markers,including reactive oxygen species(ROS),malondialdehyde(MDA),superoxide dismutase(SOD),catalase(CAT)and glutathione peroxidase(GSH-Px),were determined.Western blot was conducted to quantify the protein expression levels of B-cell lymphoma-2(Bcl-2),Bcl-2-associated X protein(Bax),p38 mitogen-activated protein kinase and phosphorylated p38(p-p38)in brain tissues.The expression levels of ZFAS1 and caspase-3 mRNA were determined by RT-qPCR.RESULTS:Knockdown of ZFAS1 in db/db mice significantly improved cognitive function,alleviated hippocampal neuronal damage,and reduced body weight and blood glucose levels(P<0.01).More-over,oxidative stress was mitigated,as evidenced by decreased MDA and ROS levels(P<0.01)and increased activity of antioxidant enzymes,GSH-Px,SOD and CAT(P<0.01 or P<0.05).Meanwhile,ZFAS1 silencing down-regulated Bax and p-p38/p38 protein expression(P<0.01 or P<0.05)while up-regulating Bcl-2(P<0.01).Consistently,RT-qPCR confirmed significant down-regulation of ZFAS1 and caspase-3 mRNA levels(P<0.01).CONCLUSION:lncRNA ZFAS1 is highly expressed in the hippocampus of DE mice.Down-regulation of ZFAS1 expression enhances cognitive func-tion,suppresses oxidative stress,and inhibits neuronal apoptosis,thereby attenuating neural damage in DE.
