Based on the thinking of programmatization and proceduralization, this study integrated traditional Chinese medicine (TCM) classic theories with modern knowledge expression technologies to construct a "formula-symptom" syndrome differentiation thinking model centered on "symptom clustering-main syndrome screening-formula adaptation", and explored the standardization and intelligentization path of TCM syndrome differentiation and treatment. By establishing the mapping relationship model between formulas and syndromes including quantitative weight analysis of chief, deputy, assistant and envoy medicines, designing the logical hierarchical structure of formula-syndrome decision tree (application of three-level decision tree and fuzzy logic), and formulating the procedural design of four diagnostic methods (structured collection, correlation model, and dynamic correction mechanism), the standardization and visualization of the syndrome differentiation process are realized. This model can be transformed into the core data set for artificial intelligence training. Through ternary knowledge graph and machine learning algorithms, it can improve the repeatability of syndrome differentiation and the efficiency of diagnosis and treatment, and implement the strategy of "group model + individual modification" to balance the conflict between quantification and individualization. The core value of this model lies in promoting the objectification and precision development of TCM syndrome differentiation and treatment through the integration of traditional syndrome differentiation thinking and modern system science.

Objective: To analyze the nucleic acid load of human parvovirus B19 in major commercially available blood products in China, including human albumin, human intravenous immunoglobulin, human rabies immunoglobulin and various coagulation factor products, aiming to provide evidence for improving blood product manufacturing processes and quality control of source plasma. Methods: A total of 98 batches of coagulation factor products were tested for human parvovirus B19 nucleic acid using real-time fluorescent quantitative PCR, including 42 batches of human prothrombin complex, 35 batches of human coagulation factor Ⅷ, and 21 batches of human fibrinogen. Additionally, 6 batches of human albumin, 6 batches of human intravenous immunoglobulin, and 38 batches of human rabies immunoglobulin were tested for human parvovirus B19 nucleic acid. Results: Human parvovirus B19 nucleic acid were undetectable in human albumin, human intravenous immunoglobulin and human rabies immunoglobulin. Among the 98 batches of coagulation factor products tested for human parvovirus B19 nucleic acid, B19 nucleic acid reactivity rate was 69.0% (29/42) for human prothrombin complex batches, but nucleic acid concentration were all significantly lower than 10
IU/mL. The reactivity rate of B19 nucleic acid in 35 batches of human coagulation factor Ⅷ was 48.6% (17/35), with nucleic acid concentration all below 10
IU/mL. The reactivity rate of B19 nucleic acid in 21 batches of human fibrinogen was 61.9% (13/21), with nucleic acid concentration all below 10
IU/mL. Conclusion: No human parvovirus B19 has been detected in human albumin, human intravenous immunoglobulin, or human rabies immunoglobulin. Human parvovirus B19 nucleic acid may exist in commercially available coagulation factor products, highlighting the need for enhanced screening of human parvovirus B19 nucleic acid in these products. It is also recommended that B19 viral nucleic acid testing be conducted on source plasma, particularly for coagulation factor products.

OBJECTIVE:
To review the research progress and challenges of poly (L-lactic acid) (PLLA) membrane in preventing tendon adhesion.
METHODS:
The relevant literature at home and abroad in recent years was extensively searched, covering the mechanism of tendon adhesion formation, the adaptation challenge and balancing strategy of PLLA, the physicochemical modification of PLLA anti-adhesion membrane and its application in tendon anti-adhesion. In this paper, the research progress and modification strategies of PLLA membranes were systematically reviewed from the three dimensions of tissue adaptation, mechanical adaptation, and degradation adaptation.
RESULTS:
The three-dimensional adaptation of PLLA membrane is optimized by combining materials (such as hydroxyapatite, polycaprolactone), structural design (multilayer/gradient membrane), and drug loading (anti-inflammatory drug). The balance between anti-adhesion and pro-healing is achieved, the mechanical adaptation significantly improve, and degradation is achieved (targeting the degradation cycle to 2-4 weeks to cover the tendon repair period).
CONCLUSION
In the future, it is necessary to identify the optimal balance point of three-dimensional fitness, unify the evaluation criteria and solve the degradation side effects through the co-design of physicochemical modification and drug loading system to break through the bottleneck of clinical translation.

Objective:To compare the clinical efficacy of endoscopic submucosal dissection (ESD) and endoscopic mucosal resection (EMR) in the treatment of elderly patients with early gastric cancer.Methods:Ninety-two elderly patients with early gastric cancer admitted to the 923th Hospital of the Joint Service Support Force of PLA from June 2019 to February 2022 were enrolled, and they were divided into ESD group (60 cases) and EMR group (32 cases) according to different surgical methods. The ESD group was treated with ESD surgery, while the EMR group was treated with EMR surgery. The short-term clinical efficacy of the two groups was compared. The gastric function including pepsinogen Ⅰ(PGⅠ), pepsinogenⅡ(PGⅡ), PGⅠ /PGⅡ ratio and the tumor markers including carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9), carbohydrate antigen 125 (CA125), and invasion genes within the lesion including vascular endothelial growth factor C (VEGF-C), E-cadherin, microtubule depolymerin (Stathmin), Krüppel like factor 4 (KLF4) were detected before and 3 d after surgery. Followed up for 1 year, the recurrence rate and complications between the two groups were compared.Results:All of 92 patients successfully removed the diseased tissue as a whole, and the R0 and R1 resection rate between the two groups had no statistical differences ( P>0.05). At 3 d after surgery, the levels of PG Ⅰand PGⅠ/PG Ⅱin the both groups were higher than those before surgery, and the level of PG Ⅱ in the both groups was lower than that before surgery; the levels of PG Ⅰand PGⅠ/PG Ⅱ in the ESD group were higher than those in the EMR group: (86.50 ± 8.23) μg/L vs. (77.47 ± 7.40) μg/L, 5.29 ± 0.54 vs. 3.65 ± 0.50; the level of PG Ⅱ ratio in the ESD group was lower than that in the EMR group: (16.34 ± 3.05) μg/L vs. (21.20 ± 3.27) μg/L, there were statistical differences ( P<0.05). At 3 d after surgery, the levels of CEA, CA19-9 and CA125 in the two groups were decreased, and the levels of the above indicators in the ESD group were lower than those in the EMR group: (2.42 ± 0.45) μg/L vs. (3.29 ± 0.40) μg/L, (8.55 ± 2.10) kU/L vs. (10.62 ± 2.76) kU/L, (13.75 ± 4.28) kU/L vs. (17.20 ± 4.90) kU/L, there were statistical differences ( P<0.05). At 3 d after surgery, the mRNA expression of E-cadherin and KLF4 in the two groups were increased, and the mRNA expression of VEGF-C, Stathmin in the two groups were decreased, and the mRNA expression of E-cadherin and KLF4 in the ESD group were lower than those in the EMR group: 2.89 ± 0.31 vs. 3.03 ± 0.21, 2.90 ± 0.28 vs. 3.12 ± 0.37, and the mRNA expression of VEGF-C, Stathmin in the ESD group were higher than those in the EMR group: 0.45 ± 0.11 vs. 0.41 ± 0.07, 0.52 ± 0.23 vs. 0.43 ± 0.09, there were statistical differences ( P<0.05). The complication rate in the ESD group was lower than that in the EMR group: 5.00%(3/60) vs. 23.33% (14/60) , there was statistical difference ( χ2 = 8.32, P<0.01). The recurrence rate in the 1-year between the two groups had no statistical difference ( P>0.05). Conclusions:Compared with EMR, ESD is effective in the treatment of elderly early gastric cancer, which can better correct the abnormal secretion of pepsinogen, promote the functional recovery of gastric cells and glands, reduce the level of serum tumor markers, inhibit the metastasis and proliferation of tumor cells, and has good safety.

Iron is indispensable for the viablility of nearly all living organisms, and it is imperative for cells, tissues, and organisms to acquire this essential metal sufficiently and maintain its metabolic stability for survival. Disruption of iron homeostasis can lead to the development of various diseases. There is a robust connection between iron metabolism and infection, immunity, inflammation, and aging, suggesting that disorders in iron metabolism may contribute to the pathogenesis of arthritis. Numerous studies have focused on the significant role of iron metabolism in the development of arthritis and its potential for targeted drug therapy. Targeting iron metabolism offers a promising approach for individualized treatment of arthritis. Therefore, this review aimed to investigate the mechanisms by which the body maintains iron metabolism and the impacts of iron and iron metabolism disorders on arthritis. Furthermore, this review aimed to identify potential therapeutic targets and active substances related to iron metabolism, which could provide promising research directions in this field.

BACKGROUND:Hydrogel microparticles,due to their porous and injectable properties,have demonstrated unique advantages in biomedical fields,such as the delivery of cells and bioactive factors/drugs,the construction of tissue repair scaffolds.They have broad application prospects. OBJECTIVE:To review the latest research progress and discuss the key problems and challenges in the research of bone tissue engineering based on hydrogel microparticles. METHODS:The relevant articles in PubMed and CNKI were searched by computer.The English key words were"hydrogels,microparticles,microspheres,microcarriers,bone,bone defect,bone repair,bone healing,bone tissue engineering"while the Chinese key words were"hydrogels,microparticles,microspheres,bone tissue engineering,bone defect,bone repair,bone regeneration".The retrieval period was from 2002 to 2022,and 127 articles were finally included for review. RESULTS AND CONCLUSION:(1)At present,various hydrogel microparticles have been developed for use in bone tissue engineering strategies,for example,hydrogel microparticles carrying cells or bioactive factors/drugs,hydrogel microparticles as biological scaffolds,stimulus-responsive hydrogel microparticles,biomineralized hydrogel microparticles,hydrogel microparticles combined with other biological materials.(2)Bone tissue engineering repair strategies based on hydrogel microparticles mainly regulate bone repair by promoting stem cell recruitment and osteogenic differentiation,regulating the local inflammatory microenvironment and promoting angiogenesis at the site of injury.However,the present studies did not deeply explore the effect of bone tissue engineering based on hydrogel microparticles on the recruitment and differentiation of endogenous stem cells and the regulation of the inflammatory microenvironment by the physical and chemical properties of hydrogel microparticles.The long-term in vivo adverse reactions of hydrogel microparticles have not been explored yet,and it is difficult to mass-produce them,thus future research needs to strengthen the mechanism exploration and technical route,so as to provide a reasonable reference for the development of hydrogel microparticles that can be used for clinical transformation.

YOU Zaijing,a doctor of Wumen region,and a famous expert of Treatise on Pathogenic Diseases, also made great achievements in warm diseases. He cleared the source of cold pathogenic diseases and warm diseases, distinguish the difference between them. He put forward the importance of correcting and understanding the disease nomenclature. He explained the names of warm diseases,wind-warm disonder, pestilence,damp-warm disease,warm toxin and warm malaria.He divided warm diseases into newly acquired warm disease, warm disease caused by incubating pathogens, warm disease mixed with dampness and pestilence.He used pungent and cool natured drugs and the method of regulating lung to treat wind warm diseases.In the treatment of warm toxin, he used the method of venting pathogen with cool-scattered natured drugs. In the treatment of warm disease caused by incubating pathogens,he used the method of clearing away heat, nourishing yin and venting pathogen. In the treatment of dampness-warm disease, he used the method of eliminating dampness and heat separately. In the treatment of pestilence, he took the location of disease as the core.According to the different disease locations of the pestilence, different treatment methods and prescriptions were selected.He listed five methods of treating pestilence and established a theoretical framework for the treatment of pestilence,embodying the thought of guiding the trend along the development.He put forward the theory of Six Channels directing Cold and Warm early.He tried to use the syndrome differentiation of six channels system to direct all exogenous diseases such as cold pathogenic diseases and warm diseases. He was the pioneer advocator of the cold-warm combined theory. His views on warm diseases had a profound impact on later doctors. This paper summarizes his main points, analyzes his theory, and provides inspiration for the diagnosis and treatment of warm diseases.
