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.

Bacterial infection is a major threat to global public health, and can cause serious diseases such as bacterial skin infection and foodborne diseases. It is essential to develop a new method to rapidly diagnose clinical multiple bacterial infections and monitor food microbial contamination in production sites in real-time. In this work, we developed a 4-mercaptophenylboronic acid gold nanoparticles (4-MPBA-AuNPs)-functionalized hydrogel microneedle (MPBA-H-MN) for bacteria detection in skin interstitial fluid. MPBA-H-MN could conveniently capture and enrich a variety of bacteria within 5 min. Surface enhanced Raman spectroscopy (SERS) detection was then performed and combined with machine learning technology to distinguish and identify a variety of bacteria. Overall, the capture efficiency of this method exceeded 50%. In the concentration range of 1 × 10⁷ to 1 × 10¹⁰ colony-forming units/mL (CFU/mL), the corresponding SERS intensity showed a certain linear relationship with the bacterial concentration. Using random forest (RF)-based machine learning, bacteria were effectively distinguished with an accuracy of 97.87%. In addition, the harmless disposal of used MNs by photothermal ablation was convenient, environmentally friendly, and inexpensive. This technique provided a potential method for rapid and real-time diagnosis of multiple clinical bacterial infections and for monitoring microbial contamination of food in production sites.

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.

This paper summarized Professor LI Haisong's clinical experience in treating spermatorrhea based on the view of "spirit controlling essence and qi". It is emphasized that the heart spirit has the function of controlling the essence and qi of the human body， believing the frenetic stirring of heart spirit and the insecurity of essence gate are the core pathogenesis of spermatorrhea， LI advocates to regulate the heart spirit first and take into account of the zang-fu organs， essence and qi simultaneously for the treatment. Treatment should be performed according the clinical syndromes differentiatied. For those with heart spirit failing to nourish syndrome， it is recommended to supplement heart qi， nourish spirit and consolidate essence with self-made Yangxin Mijing Formula （养心秘精方）. In case of heart fire hyperactivity， the method of clearing heart heat and draining fire， calming spirit and consolidating essence should be used， and self-made Xiexin Gujing Formula （泻心固精方） is recommended. For heart-liver qi constraint， it is advised to soothe the liver and calm heart， calm the mind and regulate essence with self-made Jieyu Anshen Tiaojing Formula （解郁安神调精方） which is a modifcation to Chaihu Shugan Powder （柴胡疏肝散）. In terms of deficiency of both heart and liver， the treatment principle is supplementing spleen and nourishing heart， calming the mind and controlling essence， for which self-made Xinpi Tongtiao Shejing Formula （心脾同调摄精方） modified from Guipi Decoction （归脾汤） can be used. For deficiency of both heart and kidney， it is better to nourish the kidney and calm heart， calm the mind and consolidate essence with self-made Xinshen Liangzi Tianjing Formula （心肾两滋填精方） that modified from Shuilu Erxian Elixir （水陆二仙丹） and Wuzi Yanzong Pill （五子衍宗丸）. Prescriptions are used to treat the root by harmonizing the zang-fu organs， nourish the spirit by regulating qi and blood， and calm the mind by taking special medi-cinals， and they should be flexibly modified according to the disease.

In the differentiation and treatment of recurrent urinary tract infection （rUTI） from the perspective of the seminal orifice， it is proposed that the urinary tract belongs to the category of "seminal orifice"， and the physiological process of urination is closely related to the function of the seminal orifice. From the three dimensions of orifice body， orifice pivot and orifice spirit， the physiological relationship between seminal orifice and the function of five zang-organs （脏） is constructed， that is， lung heat， yin damage and pathogen counter-restriction lead to malnutrition of orifice body； burning heart fire and spirit disorder lead to unfavorable orifice spirit， and kidney deficiency， liver constraint and spleen stagnation lead to unfavorable orifice pivot. In the early stage of rUTI， there is usually unfavo-rable orifice pivot， for which the treatment principle should be treating the root and the branch simultaneously， consi-dering both deficiency and excess， and paying attention to the management of accompanied symptoms. Zishui Qinggan Beverage （滋水清肝饮） and Modified Shenzhuo Decoction （肾着汤加减） are often selected based on syndrome differentiation. In the middle stage， lack of nourishment of the orifice body and unfavorable orifice spirit and pivot coexist， and the treatment should be draining the orifice and unblocking strangury， commonly withmodified Qingxin Lianzi Beverage （清心莲子饮）. In the late stage， loss of nourishment of the orifice body is the main pathogenesis， and it is necessary to further nourish the orifice body to prevent recurrence， and modifed Wuzi Yanzong Pills and Erxian Decoction （五子衍宗丸合二仙汤） is often used. Furthermore， the specific medicinals should be selected targeting at the orifice body， orifice pivot， and orifice spirit， so as to nourish orifice body by dispelling external pathogens and rectify healthy qi， to drain orifice pivot by freeing emotions and minds and unblocking qi movement， and to calm orifice spirit by unblocking heart and kidney and nourishing heart spirit.

Nonalcoholic steatohepatitis (NASH) is a spectrum of chronic liver disease characterized by hepatic lipid metabolism disorder. Recent reports emphasized the contribution of triglyceride and diglyceride accumulation to NASH, while the other lipids associated with the NASH pathogenesis remained unexplored. The specific purpose of our study was to explore a novel pathogenesis and treatment strategy of NASH via profiling the metabolic characteristics of lipids. Herein, multi-omics techniques based on LC-Q-TOF/MS, LC-MS/MS and MS imaging were developed and used to screen the action targets related to NASH progress and treatment. A methionine and choline deficient (MCD) diet-induced mouse model of NASH was then constructed, and Schisandra lignans extract (SLE) was applied to alleviate hepatic damage by regulating the lipid metabolism-related enzymes CES2A and CYP4A14. Hepatic lipidomics indicated that MCD-diet led to aberrant accumulation of phosphatidylethanolamines (PEs), and SLE could significantly reduce the accumulation of intrahepatic PEs. Notably, exogenous PE (18:0/18:1) was proved to significantly aggravate the mitochondrial damage and hepatocyte apoptosis. Supplementing PE (18:0/18:1) also deteriorated the NASH progress by up regulating intrahepatic proinflammatory and fibrotic factors, while PE synthase inhibitor exerted a prominent hepatoprotective role. The current work provides new insights into the relationship between PE metabolism and the pathogenesis of NASH.

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·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.

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.
