The concept of holism is the core idea of traditional Chinese medicine （TCM）. Various organs and tissues coordinate with each other to maintain the body's life activities， with a close and mutual influence between the spleen， stomach， and the central nervous system （brain）. The gut-brain axis plays an important bridging role between the digestive system and the central nervous system， achieving bidirectional information exchange between the brain and the gastrointestinal tract through complex neuroendocrine and immune mechanisms. The theory of cross-organ interaction involves the mutual influence， coordination， and integration between different organs and systems； multimodality， on the other hand， utilizes multiple sensory modalities， such as vision， hearing， and touch， to convey information. By combining TCM theory with the gut-brain axis theory， a cross-organ multimodal characterization system is established to explore its mechanism and application value in refractory diseases such as functional gastrointestinal disorders， precancerous gastrointestinal diseases， Alzheimer's disease， Parkinson's syndrome， type 2 diabetes， and depression.

BACKGROUND:Traditional Chinese medicine has been proved to have a significant role in anti-osteoporosis,and the effectiveness and mechanism of Ligustri Lucidi Fructus and its the active ingredients against osteoporosis have gradually gained the attention of scholars.OBJECTIVE:To analyze and summarize the research progress of Ligustri Lucidi Fructus and its active ingredients against osteoporosis in vitro and in vivo.METHODS:We searched the relevant literature included in CNKI and PubMed databases using the search terms of"Osteoporosis,Bone marrow mesenchymal stem cells,Osteoblast,Osteoclast,Ligustri Lucidi Fructus,Signal path"in Chinese and English,respectively.According to the needs of the research,we established the corresponding criteria and screened the literature.A total of 82 papers were included in the final review.RESULTS AND CONCLUSION:(1)The active ingredients of Ligustri Lucidi Fructus that exert anti-osteoporotic effects in vitro and in vivo mainly involve the following:Salidroside activates the Wnt/β-catenin signaling pathway by inhibiting the expression of Sclerostin and Dickkopf-related protein 1.This activation process enhances the expression of phosphorylated low-density lipoprotein receptor-related protein 6 in ovariectomized rats and primary osteoblasts,while decreasing the expression of glycogen synthase kinase 3β.Further,it promotes the expression of β-catenin,runt-related transcription factor 2 and cellular myelocytomatosis oncogene in the nucleus,thereby promoting the bone formation capacity of osteoblasts.The advantage is that it acts directly on osteoblasts to promote bone formation,which provides a new strategy for the treatment of osteoporosis.(2)Olive bittersweet significantly increases bone mineral density and regulates bone metabolism by decreasing terminal interleukin-6 and alkaline phosphatase concentrations in Sprague-Dawley rats.In vitro experiments showed that olive bittersweet promotes the proliferation of osteoblasts and up-regulates the protein and mRNA expression of osteoprotegerin,while inhibiting the protein and mRNA expression of receptor activator of nuclear factor-κB ligand.This mechanism of action is closely related to the regulation of the balance of the osteoprotegerin/receptor activator of nuclear factor-κB ligand system,demonstrating the advantage of increasing bone mineral density and maintaining bone health by regulating factors related to bone metabolism,but there is no significant effect on Ca2+concentration,which may limit its use in some specific types of osteoporosis.(3)By decreasing the expression of phosphatidylinositol 3 kinase,reducing the phosphorylation of protein kinase B and the expression of osteoclast-specific marker protein c-Fos,pineconiferin effectively inhibits the activation of phosphatidylinositol 3 kinase/protein kinase B/c-Fos pathway in osteoclasts.This inhibition reduces the proliferation and maturation of osteoclasts,which can help to reduce bone resorption.The advantage of this inhibition is that it can directly target osteoclasts,which provides a new target for osteoporosis treatment.However,the specific regulatory mechanism of osteoclasts needs to be studied in depth,and its long-term effect and safety need to be further evaluated.(4)The active ingredients of Ligustri Lucidi Fructus have shown good therapeutic effects on osteoporosis,but their mechanism of action is complex,involving the interaction of multiple genes,proteins and signaling pathways.In the future,large-scale clinical trials need to be carried out to verify its effectiveness and safety,and the strategy of combining the active ingredients of Ligustri Lucidi Fructus with other drugs needs to be further explored in order to obtain better therapeutic effects.

Objective To explore the feasibility and safety of ultrasound-guided percutaneous microwave ablation for unresectable pancreatic cancer.Methods Totally 84 patients who underwent ultrasound-guided percutaneous microwave ablation for unresectable pancreatic cancer were enrolled,and the technical success rate,complete ablation rate,complication rate,pain relief rate and survival time,etc.were observed.Results The median age of 84 cases was 61.5 years.Totally 86 tumors,including 44.19％(38/86)at the head/neck and 55.81％(48/86)at the body/tail of pancreas were detected,and a total of 85 ablation sessions were performed with the median ablation energy applied per tumor of 9.90(1.08,21.60)kJ and the complete ablation rate of 42.86％(36/84).The technical success rate was 100％(85/85).Thirty-nine complication events occurred in 25 cases,no ablation-related death.Among 34 patients underwent ablation mainly for pain symptoms,the pain score decreased from(6.22±1.12)points before treatment to(1.94±1.64)points after treatment(P＜0.001).During 6.8(3.3,12.9)months' follow-up,the mean survival time was(8.5±6.7)months,and all 47 patients died due to tumor progression.Conclusion Ultrasound-guided percutaneous microwave ablation was safe and feasible for unresectable pancreatic cancer.

Immune checkpoint inhibitors （ICIs） have shown good efficacy in tumor treatment and have changed the landscape of tumor treatment. However， some patients treated with ICIs have not only failed to achieve the desired therapeutic effect， but also developed an atypical response pattern of abnormally accelerated tumor growth， namely hyperprogressive disease （HPD）. The pathogenesis of HPD is still unclear and it is difficult to diagnose， which poses a challenge for clinical identification and treatment decisions. Exploring the underlying mechanism of HPD is important to improve the effect of immunotherapy. Based on the theory of "Yang deficiency and toxic knot"， this paper discussed the mechanism of HPD in immunotherapy from the perspective of "spleen and kidney Yang deficiency and hefty toxic pathogens". It was concluded that the inactivation of p53 oncogene and immunosuppressive microenvironment were the manifestations of the deficiency of healthy qi in the body and declined yang in the spleen and kidney， serving as an important basis for the occurrence of HPD. Adverse reactions caused by ICIs belong to the category of "drug toxicity". The occurrence and development of murine double minute 2 （MDM2）/murine double minute 4 （MDM4） activation， epidermal growth factor receptor （EGFR） mutation， and tumor inflammatory microenvironment are the manifestations of the hyperactivity of pathogenic Qi， conflict of cancer toxicity and drug toxicity， and being hefty by virtue of deficiency， which can promote the abnormal proliferation of tumor cells， and they are the core pathogenic elements of HPD and are closely related to disease prognosis. In terms of treatment， under the guidance of the theory of "five views on differentiation and treatment" （time-space view， core view， symptom view， precision view， and disease-before-onset view）， which was summarized according to the clinical practice of this research team， this paper， taking the prevention and treatment of HPD as the entry point， formulated traditional Chinese medicine （TCM） compounds to reinforce healthy Qi and warm Yang and realize the dynamic management of the whole spatiotemporal cycle， and removed toxins and resisted cancer to realize the all-round systemic intervention of the specimen. Additionally， targets were enriched in the macro-clinical manifestations and microscopic pathological changes of HPD to improve the targeting of drug selection and the precision of prevention and treatment， giving full play to the unique therapeutic advantages of TCM， and providing new ideas for the clinical application of TCM in the prevention and treatment of HPD.

Objective:To explore the therapeutic effect and psychological influence of biofeedback pelvic floor muscle training on fecal incontinence after anorectal surgery in children.Methods:A retrospective case-control study.A total of 37 children who were admitted to the First Affiliated Hospital of Xinxiang Medical University from July 2021 to April 2023 for fecal incontinence after anorectal surgery were collected.Biofeedback pelvic floor muscle training was performed with a Laborie biofeedback therapy device, and pelvic floor muscle contraction function exercise was performed no less than 200 times a day.The anal canal current intensity, basic motion myoelectric value, contractile myoelectric difference and continuous anal contraction time were measured at before treatment, at the end of 1 course, 1 month and 1 year after treatment.Ten healthy children of the same age were selected as the healthy control group.The Strengths and Difficulties Questionnaire was used for psychological evaluation at before treatment and 1 year after treatment.Paired sample t test and independent sample t test were used to compare and analyze the results of this study. Results:Before treatment, at the end of 1 course, 1 month and 1 year after treatment, the anal canal current intensity of children with fecal incontinence were(11.32±1.92) mA, (10.22±1.28) mA, (8.45±1.09) mA, and(7.80±1.23) mA, respectively; the anal canal basic motion myoelectric value were(235.58±55.03) μV, (185.65±34.30) μV, (124.81±36.56) μV, and(93.99±28.29) μV, respectively; the anal canal contractile myoelectric difference were(45.64±20.38) μV, (64.20±16.59) μV, (93.63±25.53) μV, and(109.83±26.95) μV, respectively; the continuous anal contraction time were(1.27±0.43) s, (1.58±0.40) s, (2.04±0.39) s, and(2.47±0.38) s, respectively.These parameters before treatment, at the end of 1 course and 1 month after treatment were significantly different from those in the healthy control group[(7.20±1.09) mA, (88.65±21.76) μV, (120.73±27.57) μV, (2.68±0.29) s](all P<0.05).These parameters at 1 year after treatment were significantly different from those before treatment and 1 month after treatment(all P<0.05).However, there were no significant differences in these parameters between the healthy control group and the treatment group at 1 year after treatment(all P>0.05).There were statistically significant differences in emotional symptoms, hyperactivity symptoms, peer interaction, prosocial behavior and difficulty scores before and after treatment[(3.46±1.88) points vs.(2.59±1.32) points, (5.78±2.12) points vs.(3.70±1.78) points, (3.05±1.72) points vs.(2.49±1.30) points, (7.30±1.54) points vs.(8.27±1.39) points, (21.57±4.57) points vs.(18.54±3.14) points](all P<0.05). Conclusions:Biofeedback pelvic floor muscle training is a reliable and non-invasive method for the treatment of postoperative fecal incontinence after anorectal surgery in children and can effectively relieve the psychological and behavioral problems caused by fecal incontinence in children.

Astrocytes are important nerve cells in the central nervous system （CNS）， which mainly play a key role in nutrition and support. Astrocytes and neurons undergo close energy coupling and substance coupling， which are closely related and interact with each other. In recent years， many studies have shown that the astrocyte-neuron coupling imbalance plays a central role in the occurrence and progression of Alzheimer's disease （AD） and serves as an important therapeutic target receiving increasing attention. According to traditional Chinese medicine （TCM） theory， the main pathogenesis of AD is kidney deficiency and marrow inadequacy， and in clinical medication， kidney-tonifying and marrow-filling TCM prescriptions are often employed with satisfactory results achieved. As reported， many kidney-tonifying and marrow-filling prescriptions exhibit regulatory and protective effects on the imbalance of astrocyte-neuron coupling， suggesting that the effect of kidney-tonifying and marrow-filling prescriptions in treating AD may have some internal relationship with its regulation of the imbalance of astrocyte-neuron coupling. This article reviewed the underlying internal relationship between the imbalance of astrocyte-neuron coupling and the pathogenesis of kidney deficiency and marrow inadequacy in AD and the research progress in the intervention mechanism of TCM for tonifying the kidney and filling the marrow.

ObjectiveTo explore the mechanism of Dihuang Yinzi in improving astrocyte injury and glycolysis in Alzheimer's disease （AD） mice via regulating the phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway， thereby improving the cognitive function of AD mice. MethodForty male APP/PS1 transgenic mice aged four months were randomly divided into a model group and a model + Dihuang Yinzi （0.25 g·kg^-1） group， with 20 mice in each group. Forty C57BL/6J mice with the same background and same age were randomly divided into a control group and a control + Dihuang Yinzi （0.25 g·kg^-1） group， with 20 mice in each group. The mice in the control + Dihuang Yinzi group and the model + Dihuang Yinzi group were administered with Dihuang Yinzi by gavage， and those in the control group and the model group received an equal volume of sterilized normal saline， once a day for 150 days. Morris water maze test was performed to test the ability of navigation and space exploration of mice. The protein expression of p-PI3K， PI3K， p-Akt， Akt， phosphofructokinase-1 （PFK-1）， and aldehyde dehydrogenase 3 family member B2 （ALDH3B2） in mouse brain tissues was measured by Western blot. An immunofluorescence assay was performed to detect astrocyte morphology and the expression level of ALDH3B2. ResultAs compared with the control group， the model group showed prolonged escape latency during the 2^nd to 5^th days of the location-based navigation （P<0.05， P<0.01）， reduced number of times crossing the target area of the platform， shortened residence time in the target quadrant （P<0.05， P<0.01）， prolonged residence time in the opposite quadrant （P<0.05）， increased surface area of the cell body and total length of cell protrusions of astrocytes （P<0.05， P<0.01）， and down-regulated protein expression of p-PI3K， p-Akt， ALDH3B2， and PFK-1 （P<0.01）， while the above experimental indexes were not significantly different in the control + Dihuang Yinzi group. Compared with the model group， the model + Dihuang Yinzi group showed shortened escape latency of APP/PS1 mice during the 2^nd to 5^th days of the location-based navigation （P<0.05， P<0.01）， increased number of times crossing the platform， prolonged target quadrant residence time （P<0.05， P<0.01）， shortened residence time in the opposite quadrant （P<0.05）， reduced surface area of the cell body and total length of cell protrusions of astrocytes （P<0.05）， and up-regulated protein expression of p-PI3K， p-Akt， ALDH3B2， and PFK-1 （P<0.01）. ConclusionDihuang Yinzi can improve the learning and memory ability of AD mice by activating the PI3K/Akt signaling pathway and up-regulating the protein expression of PFK-1 and ALDH3B2 to protect against astrocyte injury in brain tissues and improve glycolysis.

ObjectiveTo explore the mechanism of Dihuang Yinzi （DHYZ）in improving astrocyte injury in the brain and regulating energy metabolism and autophagy disorder in Alzheimer's disease （AD） model mice. MethodForty male APP/PS1 transgenic mice aged four months were randomly divided into a model group and a model + DHYZ group （2.5 g·kg^-1）， with 20 mice in each group. Forty C57BL/6J mice with the same background and same age were randomly divided into a control group and a control + DHYZ group （2.5 g·kg^-1）， with 20 mice in each group. The mice in the control group and the model group were administered with an equal volume of sterilized normal saline by gavage， once a day for 150 days. Novel object recognition test and step-down test were performed to evaluate the learning and memory ability of mice. The expression of glial fibrillary acidic protein （GFAP） in astrocytes was detected by immunofluorescence and Western blot. High-performance liquid chromatography （HPLC） was used to detect adenosine triphosphate （ATP）， adenosine diphosphate （ADP）， and adenosine monophosphate （AMP） in brain tissues of mice， and the data obtained were used to calculate energy charge （EC） levels. The phosphorylation levels of liver kinase B1 （LKB1）， adenosine 5′-monophosphate （AMP）-activated protein kinase （AMPK）， UNC-51-like kinase 1 （ULK1）， and mammalian target of rapamycin （mTOR） and the expression levels of autophagy-related proteins Beclin-1， microtuble-associated protein 1 light chain 3 （LC3）-Ⅱ/LC3-Ⅰ， and p62 in mouse brain were measured by Western blot. ResultCompared with the control group， the model group showed decreased novel object recognition index， shortened retention latency， increased error times in the step-down test， up-regulated protein expression of GFAP， decreased content of ATP， ADP， and EC in brain tissues， elevated AMP ， increased levels of p-AMPK， p-LKB1， and p-mTOR， and protein expression of p62 ， and down-regulated p-ULK1 level and protein expression of Beclin-1 and LC3-Ⅱ/LC3-Ⅰ（P<0.01）， while the above experimental indexes were not significantly different in the control + DHYZ group. Compared with the model group， the model + DHYZ group showed increased novel object recognition index（P<0.05）， prolonged retention latency（P<0.01）， decreased error times（P<0.01） in the step-down test， reduced protein expression of GFAP（P<0.05）， increased content of ATP， ADP， and EC in brain tissues （P<0.05， P<0.01）， decreased AMP content（P<0.05）， reduced p-AMPK， p-LKB1， and p-mTOR levels and protein expression of p62， and up-regulated p-ULK1 level and protein expression of Beclin-1 and LC3-Ⅱ/LC3-Ⅰ（P<0.01）. ConclusionBy protecting astrocytes， DHYZ can improve energy metabolism and autophagy disorder in AD mice to improve the learning and memory ability of model mice.
