Diabetic kidney disease （DKD） is one of the most common microvascular complications of diabetes. Traditional Chinese medicine （TCM） plays a unique role in improving clinical symptoms， reducing proteinuria， and delaying the initiation of dialysis. Over time， scholars have held diverse views on the etiology， pathogenesis， and treatment strategies of DKD. This paper systematically reviews the etiology and pathogenesis， syndrome differentiation and treatment， and medication rules of DKD， aiming to provide a reference for clinical practice. Regarding etiology， DKD is closely related to insufficient innate endowment， improper diet， emotional disorders， overexertion， and prolonged diabetes. Its pathogenesis evolves dynamically. Specifically， early stage is characterized by Yin deficiency with dryness-heat and subtle discharge. Middle stage involves both Qi and Yin deficiency with dampness and blood stasis. Late stage presents Yin and Yang deficiency with intrinsic turbidity toxins. Blood stasis and sugar toxicity are the core pathological factors， persisting throughout the disease course and accelerating renal collateral damage and fibrosis. In terms of diagnosis and treatment， contemporary scholars advocate stage-specific treatment， emphasize the integration of prevention and therapy， recommend whole-course management， and support comprehensive TCM and Western medicine approaches. Analysis of medication rules shows that treatment consistently addresses the core principle of deficiency at the root and excess at the surface， strengthens the body while dispelling pathogenic factors， emphasizes promoting blood circulation and removing blood stasis， consolidates the kidney and astringes essence， clears Fu-organs and eliminates turbidity and toxins， invigorates the spleen， replenishes Qi， protects the stomach， and advocates treatment based on pathogenic wind. Further refinement of the academic thoughts of classical TCM masters and research into innovative pathogenesis theories and clinically effective prescriptions are needed to enhance TCM's ability to prevent and treat major clinical diseases， including DKD.

With the rising incidence of diabetes， diabetic kidney disease （DKD） has become a significant global health burden. Although current prevention and treatment strategies can partially delay the progression of DKD， the risk of patients advancing to end-stage renal disease remains high. Since the concept of the "gut-kidney axis" was first introduced at the International Congress on Dialysis in 2011， research on the role of gut microbiota in the pathogenesis of DKD has received increasing attention. This review summarizes the current research on gut microbiota， explores the mechanisms through which it contributes to DKD development， and outlines clinical approaches for DKD prevention and treatment based on the "gut-kidney axis" theory. Evidence indicates that dietary interventions， intake of probiotics or prebiotics， use of metformin and novel antidiabetic drugs， and application of traditional Chinese medicine （TCM） compound formulas can effectively improve gut microbiota composition， influence metabolite production， and restore the intestinal mucosal barrier. These interventions can further regulate intestinal innate immunity and inflammatory responses， thereby modulating the progression of DKD. Despite challenges posed by the traditional oral administration of water-decocted TCM compound formulas and the complexity of their ingredients， increasing evidence suggests that TCM may indirectly affect the occurrence and development of DKD by modulating gut microbiota. This finding provides a new perspective on the potential mechanisms of TCM in DKD treatment and may offer novel strategies for DKD prevention and therapy.

The classic formula Mulisan is the 45th of the 93 formulas in the Catalogue of Ancient Classic Formulas （second batch） of Han medicine published by the National Administration of Traditional Chinese Medicine. It consists of Ostreae Concha， Astragali Radix， Ephedrae Radix et Rhizoma， and wheat， with the effect of replenishing qi and stopping sweating. It is a common formula in the clinical treatment with traditional Chinese medicine. This study analyzes the historical evolution， composition， dosage， original plants and their processing methods， decocting method， efficacy， indications， and modern clinical application of Mulisan by tracing， comparative analysis， and bibliometric methods. The results showed that Mulisan firstly appeared in the Pulse Classic written by WANG Shuhe in the Western Jin Dynasty. The formulation idea can be traced back to the Important Prescriptions Worth a Thousand Gold for Emergency in the Tang Dynasty. The herb composition， dosage， efficacy， and indications of Mulisan were first recorded in the Treatise on Diseases， Patterns， and formulas Related to Unification of the Three Etiologies in the Southern Song dynasty. In terms of original plants and their processing methods， Ostreae Concha is the shell of Ostrea rivularis， which should be calcined before use. Astragali Radix and Ephedrae Radix et Rhizoma are the dried roots of Astragalus membranaceus var. mongholicus and Ephedra sinica， respectively， the raw material of which should be used. Wheat is the dried mature fruit of T. aestivum， which can be used without processing， while the stir-fried fruit， being thin and deflated， demonstrates better effect. The composition of Mulisan is Ostreae Concha 8.26 g， Astragali Radix 8.26 g， Ephedrae Radix et Rhizoma 8.26 g， and wheat 7.92 g. The medicinal materials should be ground into coarse powder and decocted with 450 mL water to reach a volume of 240 mL， and the decoction should be taken warm. In modern clinical practice， Mulisan has a wide range of indications， including spontaneous sweating and night sweating caused by Yang deficiency or Qi deficiency. The clinical disease spectrum treated by Mulisan involves endocrine system diseases， neurological diseases， respiratory system diseases， and cancer. This formula plays a significant role in the treatment of internal medicine diseases in traditional Chinese medicine. This study aims to provide a scientific basis for the subsequent research， development， and clinical application of Mulisan.

WANG Qishi put forward the theory of "yang deficiency with three lackings， controlled by the spleen" in Lixu Yuanjian （《理虚元鉴》）， which regarded that yang deficiency can lead to consumptive diseases with changes of lacking essence， lacking qi， and lacking fire， so the treatment should start from the spleen to restore the middle yang urgently. This article summarised the experience of treating type 4 cardiorenal syndrome based on the theory of "yang deficiency with three lackings， controlled by the spleen"， and proposed that lacking essence is the beginning of the onset of type 4 cardiorenal syndrome， lacking qi is the gradual development of the disease， and lacking fire is the changes of the disease， and ultimately resulted in the complex situation of kidney and qi deficiency， and edema due to yang deficiency， combined with syndromes variation. In the clinical evidence， in the stage of lacking fire， therapies should warm the middle and strengthen the spleen in order to rescue the middle yang， prescribed with modified Baoyuan Decoction （保元汤） plus Lizhong Decoction （理中汤）； in the stage of lacking qi， prescriptions can add Taoren （Juglans regia）， Tubiechong （Eupolyphaga sinensis）， Fuling （Smilax glabra）， Guizhi （Neolitsea cassia） to activate blood and drain water to transport and restore the center qi； in the stage of lacking essence， prescriptions can add Gouqizi （Lycium barbarum）， Tusizi （Cuscuta chinensis）， Duzhong （Eucommia ulmoides）， Bajitian （Gynochthodes officinalis） to supplement deficiency and resolve masses to consolidate the root and supplement essence.

The neural stimulator is a core component of animal robots. While the control effect of animal robots is influenced by various factors, the performance of the neural stimulator plays a decisive role in regulating animal robots. In order to optimize animal robots, embedded neural stimulators had been developed using flexible printed circuit board technology. This innovation not only enabled the stimulator to generate parameter-adjustable biphasic current pulses through control signals, but also optimized its carrying mode, material, and size, overcoming the disadvantages of traditional backpack or head-inserted stimulators, which have poor concealment and are prone to infection. Static, in vitro, and in vivo performance tests of the stimulator demonstrated that it not only had precise pulse waveform output capability, but also was lightweight and small in size. It had excellent in vivo performance in both laboratory and outdoor environments. Our study has high practical significance for the application of animal robots.

Objective·To study the relationship between evolution and the developmental process from the perspective of DNA sequence conservation,and explore their inherent principles.Methods·First,conservation rate(CR)was established by analyzing the conservation of amino acid sequences of coding genes in 100 species to quantify the evolutionary conservation of genes.The relationship between CR and developmental potential was verified by using the feature genes involved in embryonic stem cells pathways.Secondly,cell type-specific genes and their characteristics in conservation were studied by analyzing the RNA sequencing(RNA-seq)data of the three early germ layers(ectoderm,mesoderm and endoderm)and their corresponding mature organs(brain,heart,liver,etc).Then,chromatin immunoprecipitation sequencing(ChIP-seq)data of enhancer histone H3 acetylated at lysine 27(H3K27ac)from early germ layers and mature organs were collected to search for enhancer sites and identify super enhancers in various cells and tissues by using the ROSE procedure.Functional enrichment and signaling pathway analysis of genes was used to examine the identity correlation between SEs-regulated genes and the corresponding cell characteristics,to clarify whether the SEs identified in this study were consistent with the characteristics reported in previous studies.Finally,PhastCons program was used to calculate the DNA conservation score(CS)of non-coding regulatory regions to study their relationship with developmental potential.Results·In the coding region of DNA,CR was successfully established to quantify the conservation of genes.The gene expression data of early germ layers and mature organs showed that the genes with higher conservation rate were more relevant to the stemness and early developmental process,and the differences between the tissues from early and late development could be distinguished by using CR.In the non-coding regions of DNA,it was found that the conservation of regulatory regions was also correlated with development.The CS of the SE sequences in the early developmental germ layers was significantly higher than that of the SE sequences in the corresponding mature organs.However,cell-specific typical enhancers(TEs)did not show such a trend.Conclusion·During the developmental process,CR of genes expressed in the coding region decreases,and CS of super-enhancer DNA in the non-coding region decreases.

Objective:To investigate the effectiveness of a hierarchical teaching model guided by "residency-specialty integration" in residency training and specialty training of oral and maxillofacial surgery with the training base of oral and maxillofacial surgery in Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine, as the research subject.Methods:A total of 144 trainees receiving residency training and 32 receiving specialist training were enrolled from June 2022 to April 2023 and were divided into experimental group and control group, with 72 trainees receiving residency training and 16 receiving specialist training in each group. Clinical and learning tasks were designed using the traditional model for the control group and the hierarchical teaching model guided by "residency-specialty integration" for the experimental group, and the performance of trainees in theoretical assessments and self-evaluations was recorded. SPSS 23.0 was used to perform the t-test. Results:The hierarchical teaching model guided by "residency-specialty integration" achieved a significant effect in both theoretical assessments and self-evaluations of the trainees. As for the trainees receiving specialty training, there was a significant difference in the score of theoretical assessment between the experimental group and the control group (84.56±4.05 vs. 81.13±2.78, P<0.05), and as for the trainees receiving residency training, there was also a significant difference in this score between the experimental group and the control group (84.74±4.85 vs. 82.10±4.34, P<0.01). The results of self-assessment questionnaire showed that compared with the control group, the experimental group had a higher proportion of trainees giving positive evaluations of various indicators. Conclusions:This study suggests that the hierarchical teaching model guided by "residency-specialty integration" provides an effective teaching model for residency training and specialty training of oral and maxillofacial surgery, and this model may help to enhance disciplinary interests and promote clinical practice abilities, thereby providing valuable insights for future medical education in China.

Objective:Hepatocellular carcinoma (HCC) is the fourth most dominant cancer in the world and the second leading cause of cancer-related deaths in the China. With the increase in the incidence of metabolic syndrome (MS) in the population, the correlation between MS and HCC has gradually been recognized. MS manifests as non-alcoholic fatty liver disease (shortly known as NAFLD) in the liver. A large number of research results has shown that the development of fatty liver is closely related to the occurrence of HCC, in which lipid metabolism plays a key regulatory role, and lipid metabolism is regulated by fatty acid binding protein (FABP). This study signifies the lipid metabolism analysis and the key FABP expression conditions in HCC.Methods:Data of patients who were first diagnosed with primary HCC between January 2016 to July 2019 were collected, and were divided into two groups according to the etiology, namely the viral and non-viral hepatitis-related HCC group. The relationship between MS-related factors and HCC was analyzed by t-test and chi square test. The expressions of FABP1, FABP4 and FABP5 were detected in cancer and adjacent tissues by immunohistochemistry, and the expressions of FABP1, FABP4 and FABP5 in HCC with fatty liver were detected by immunofluorescence. Finally, the expressional characteristics of the above-mentioned FABPs in HCC patients were analyzed with different clinicopathological features.Results:There were statistically significant differences in the rate of abnormal lipid metabolism and the number of abnormalities in MS-related factors between the viral and non-viral hepatitis-related HCC group. FABP1, FABP4, and FABP5 expression in HCC tissues were lower than the corresponding adjacent tumor tissues. Compared with simple HCC, FABP1, FABP4, FABP5 expression were increased in HCC tissues with steatosis, and the expression of FABP was closely related to the clinical characteristics of patients.Conclusion:Abnormal lipid metabolism is closely related to non-viral hepatitis-related HCC. The expression of lipid metabolism regulatory proteins FABP1, FABP4, and FABP5 are down-regulated in HCC tissues, but up-regulated in HCC with fatty liver, suggesting that the relationship between MS, especially dyslipidemia, and HCC should be paid attention to in clinical practice for early intervention. FABP1, FABP4, FABP5 may regulate HCC occurrence and development.

Objective: To investigate the correlation of single nucleotide polymorphisms (SNPs) in autophage-related 5 ( ATG5 ) gene promoter with acute myocardial infarction (AMI). Methods: The SNPs of ATG5 gene promoter were detected by polymerase chain reaction (PCR) and Sanger sequencing. The typing and correlation of SNPs in 378 AMI patients and 374 healthy controls were analyzed by Chi-square test, Logistic regression analysis and haplotype analysis. Results: Two SNPs of ATG5 gene promoter, rs506027 (OR=1.4, 95% CI \[0.6-3.0\], P=0.411) and rs510432 (OR=1.6, 95% CI \[0.7-3.4\], P=0.275), were found. They didn′t increase the susceptibility of AMI, and the haplotype associated with AMI was not found in the two SNPs. Conclusion The polymorphism of ATG5 gene promoter isn′t associated with the susceptibility of AMI.
