Based on the theory of "sweet-flavored medicinals retaining and restoring body fluid"， this paper proposed that the core pathogenesis of hypercoagulable state in malignant tumors is qi deficiency and fluid consumption， blood stasis and vessels stagnation， which evolves dynamically according to the pattern "qi deficiency → fluid consumption → blood stasis". Accordingly， a staged treatment system is established with the general principle of "fortifying the middle jiao， restoring fluid and activating blood circulation". In the initial stage， invigorating the spleen and boosting qi to generate body fluid， targeting the onset of middle jiao deficiency and body fluid consumption； in the middle stage， nourishing yin and unblocking collaterals to facilitate body fluid circulation， addressing the disorder of body fluid transportation and collateral injury caused by internal dryness； in the late stage， consolidating yin and resolving blood stasis to retain body fluid， resolving yin impairment， fluid exhaustion， and binding of stasis and toxin. By regulating body fluid metabolism to improve the hypercoagulable state， this system is intended to provide insights for the prevention and treatment of hypercoagulable state in malignant tumors with traditional Chinese medicine.

The infection caused by SARS-CoV-2 is a very widespread epidemic disease. Rodent models have played an important role in studying the pathogenesis and immune response of SARS-CoV-2 infection, as well as in developing drugs or vaccines for treatment and prevention. However, the accumulation of SARS-CoV-2 mutations and their rapid spread in the population have led to the emergence of mutant strains that evade host immune responses. The current SARS-CoV-2 vaccine may not be able to effectively control the spread of mutant strains, so the research and development of vaccines and drugs for the prevention and treatment of mutant strains will continue. Rodents are crucial to the study of virus etiology, transmission and pathogenesis, and have played an important role in the early development of related inactivated vaccines and antibodies.This review mainly summarizes the research progress of rodent models in SARS-CoV-2 Alpha, Beta, Gamma, Delta, Omicron mutants.

Objective To evaluate the effectiveness and safety of moxibustion for knee osteoarthritis and the methodological quality of systematic reviews(SRs).Methods SRs of moxibustion for knee osteoarthritis were retrieved from CNKI,VIP,Wanfang Data,SinoMed,PubMed,Cochrane Library,Embase and Web of Science was conducted from the establishment of the databases to February 10,2022.AMSTAR 2 was used to assess the methodological quality of SRs.The randomized controlled trials(RCTs)included in these SRs were screened and summarized according to inclusion standard.RevMan 5.4 software was used for Meta-analysis,and GRADE approach was used to assess the certainty of evidence.Results A total of 15 SRs were included.The evaluation results of the AMSTAR 2 showed that the methodological quality was very low for 14 SRs,and low for other 1 SR.A total of 36 RCTs were included.Meta-analysis results showed that compared with the non-steroidal anti-inflammatory drugs(NSAIDs),the moxibustion group had better effects on improvement of WOMAC scores[mean difference(MD)=-5.95;95%confidence interval(CI):-9.25 to-2.65;low quality],relieving pain[MD=-1.26;95%CI:-2.19 to-0.32;very low quality],and improving effective rate[risk ratio(RR)=1.16;95%CI:1.11 to 1.22;low quality].In the moxibustion group,some patients experienced blisters,and most healed in 3 days.Conclusion Moxibustion has advantages in pain reduction and improving effective rate compared with routine Western therapy for knee osteoarthritis.However,well-designed high-quality RCTs are needed for further verification.

Objective:To understand the epidemiological characteristics and spatiotemporal distribution of viral encephalitis in children and adolescents in Henan Province from 2012 to 2023.Methods:The information about viral encephalitis cases from October 1, 2012 to July 26, 2023 were collected from Zhengzhou Children's Hospital (National Children's Regional Medical Center),Henan Provincial Children's Hospital for the analyses on temporal distribution the cases, the severe illness rate, age distribution, pathogen type and imaging findings of the cases.Results:A total of 6 276 cases of viral encephalitis were included in this study after excluding cases with incomplete information. The cases mainly originated from Zhengzhou (38.96%), followed by Zhoukou (9.93%), Xuchang (8.68%), Zhumadian (7.90%) and Pingdingshan (7.39%). The cases in boys accounted for 62.13% and the cases in girls accounted for 37.87%. Most cases (72.45%) occurred in age group 7-13 years. The overall rate of severe illness cases was 4.51% from 2012 to 2023. There were significant differences in severe illness cases among different areas and years ( χ2=5.33, P=0.021; χ2=48.14, P<0.001). Enteroviruses were mainly detected (31.57%), in which Coxsackie virus was predominant (58.37%). Imaging findings showed that cerebral hemisphere damage was most common in children and adolescents with viral encephalitis (54.93%). Conclusions:From 2012 to 2023, more cases of viral encephalitis occurred in boys in Henan. Children and adolescents aged 7-13 years were the main affected group. The prevention of enteroviruses infection, especially Coxsackie virus, needs to be strengthened. Special attention should be paid to the prevention of cerebral hemisphere damage after viral encephalitis diagnosis.

The fundamental pathogenic mechanisms of inflammatory bowel disease(IBD),a chronic inflammatory illness affecting the gastrointestinal tract,are still not fully understood.Dipeptidyl peptidase Ⅳ(DPP-4)is a glycoprotein found on the cell surface that has signaling and enzymatic properties.In addition,there is growing evidence from animal models and clinical trials that DPP-4 inhibitors have potential impacts beyond only lowering blood sugar levels,such as immunomodulatory and anti-inflammatory capabilities.This article reviews the biological properties of DPP-4 and its research progress in the diagnosis and treatment of IBD.It also discusses the mechanism of DPP-4 in IBD,aiming to provide a more in-depth understanding of the role of DPP-4 in IBD.

Objective: To explore the effect of ultrasound on dentin smear layer's surface and bonding strength of the universal resin adhesive under self-etching mode. Methods: Forty mandibular third molars without caries were randomly divided into two groups; one was polished with silicon carbide sandpaper; the other was polished with silicon carbide sandpaper followed by ultrasonic treatment. Scanning electron microscope (SEM) was used to observe surface of the dentin. Treated teeth were bonded with two universal resin adhesives, Clearfil Universal Bond (pH=2.3) and All-Bond Universal (pH=3.1), and the penetration of the bonding interface was observed with a confocal laser scanning microscope (CLSM) after Rhodamine B staining. Finally, the micro tensile bond strength test was conducted to test the adhesion. Results: The SEM showed that after polishing with silicon carbide sandpaper, the smear layer of the dentin surface was scratched, and dentin tubules were almost completely blocked, with no obvious dentin tubules exposed. After ultrasonic treatment, the scratches were reduced, and a large number of dentin tubules were exposed. CLSM showed that both adhesives could penetrate the dentin along the dentin tubules more deeply after ultrasound treatment. Micro tensile bond strength tests showed that ultrasonic treatment could enhance the bonding strength of two universal resin adhesives. However, there was no statistical difference in bonding strength between these two universal resin adhesives under the same treatment. . Conclusion Ultrasound can partially remove the smear layer on dentin's surface, expose dentin tubules, and increase universal resin adhesives' penetration depth and bonding strength under self-etching mode

Syndrome differentiation and treatment is a unique mode of diagnosis in traditional Chinese medicine （TCM）. The establishment of scientific and standardized syndrome diagnosis standards is an important link to evaluate the clinical efficacy of TCM objectively and systematically， and also a prerequisite for the promotion and development of TCM to obtain international recognition. This article reviewed the basic modes and existed problems of the current syndrome diagnosis criteria， and proposed to construct a multidimensional core information set integrating the minimized core symptoms， the artificial intelligence signs， the multi-modal laboratory indicators， and multi-omics specific markers， so as to present syndrome characteristics from multiple perspectives systematically. This paper also described the basic mode， constructure， as well as the process and methodology to be adopted in the establishment of the standardized diagnostic research method. The core information set of diagnostic symptoms not only took into account the specificity of the disease， but also improved the inconsistency due to the complexity and subjectivity of the syndrome differentiation， thereby providing a methodological basis for the standardization of TCM syndrome differentiation in clinical research.
