[Objective] To perform genetic analysis on samples with weak agglutination and mixed agglutination of ABO blood group antigens in neonates, and to investigate the molecular biological characteristics of ABO subtypes in neonates. [Methods] Serological identification of ABO blood group was performed by tube method and microcolumn gel method. The ABO exons 2-7 were amplified by PCR, and the amplified products were sequenced by Sanger sequencing method to determine the genotype. [Results] Among the ABO blood group serological results of 14 neonates, 8 cases showed weakened A antigen, and 6 cases showed weakened B antigen. Seven samples were identified with ABO subtype alleles, with genotypes as A102/B101+c.538C>T, Aw26/B102, A205/O02, A205/B101(2 cases), Aw26/O02, B(A)06/O01, B101/O01(3 cases), A102/O01(2 cases), A102/B101 and B101/O02. Additionally, three other family members were also found to carry B(A)06 allele in a pedigree investigation. [Conclusion] For samples showing weakened antigens in ABO blood type identification of neonates, it is necessary to consider the possibility of ABO subtype in addition to age factors, and genetic testing can be used to prevent missed detection of ABO subtypes in neonates.

Amomi Fructus (AF) refers to the dried mature fruit of Amomum villosum A. villosum. var. xanthiondes, and A. longiligulare, all belonging to the Zingiberaceae family. As one of the renowned "Four Southern Medicines", AF is also classified as an ingredient featured by "medicinal and food homology". It is mainly produced in Guangdong, Yunnan, and Hainan provinces in China. In recent years, with the in-depth implementation of the "Healthy China" strategy, AF has gained increasing popularity among the public due to its significant medicinal value. At the same time, research on its chemical composition, pharmacological effects, and identification methods has garnered widespread attention from scholars. The chemical composition of AF is highly complex. Its primary constituents include volatile components such as borneol acetate, camphor, and borneol, as well as non-volatile components such as polysaccharides, polyphenols, and mineral elements. AF possesses a wide range of pharmacological effects, including gastrointestinal protection, lipid-lowering and weight loss, glucose-lowering, uric acid-lowering, antioxidant, anti-inflammatory, antibacterial, and analgesic activities. The identification techniques for AF, including microscopic identification, molecular biological identification, and electrochemical fingerprinting, are crucial for its quality control, safety, and efficacy. However, in recent years, there have been few comprehensive summaries of research on AF, which limits further in-depth research and high-value development and utilization of AF. This article systematically reviewed the research progress on the chemical composition, pharmacological activity, and identification methods of AF, and is expected to provide prospects for future research.

ObjectiveTo investigate the efficacy and mechanism of saffron floral bio-residues(SFB) in the treatment of hyperuricemia(HUA) combined with gouty arthritis(GA) in a compound compatibility setting. MethodScreening candidate control Chinese medicines for compound and SFB based on network target distance calculation and data analysis. After adaptive feeding of 80 SD rats for 7 days, 10 rats were randomly selected as the blank group, while the remaining 70 rats were intraperitoneally injected with 3% potassium oxonate and orally administered with 1% adenine for 14 consecutive days. On the 13th day, rats were injected with 2.5% sodium urate solution into the right ankle joint cavity to induce swelling of the joint capsule on the opposite side, inducing a HUA combined with GA model. At the same time, the modeling rats were randomly divided into 7 groups, including the model group, benzbromarone group(positive drug, 0.02 g·kg-1), Tongfengshu tablets group(9 g·kg-1), Tongfengshu granules group(9 g·kg-1), SFB granules group(3.6 g·kg-1), Plantaginis Semen granules group(3.6 g·kg-1), and new formula group(SFB replacing Plantaginis Semen in Tongfengshu granules, 9 g·kg-1), with 10 rats in each group. Each treatment group was orally administered with the corresponding drugs according to body weight, while the control and model groups were given equal volume of distilled water by gavage once a day for 14 consecutive days. After 14 days of synchronous administration and modeling, changes in gait, ankle joint swelling and mechanical pain threshold in rats were observed, and serum uric acid, creatinine, urea nitrogen and xanthine oxidase(XOD) were measured. Enzyme-linked immunosorbent assay(ELSIA) was used to detect the levels of tumor necrosis factor(TNF)-α, interleukin(IL)-1β and IL-6 in rat serum, hematoxylin-eosin(HE) staining was used to observe the pathological changes in the liver, kidney and ankle joints of rats, Western blot was used to detect the expression levels of uric acid transporter 1(URAT1), glucose transporter 9 (GLUT9), organic anion transporter 1(OAT1), adenosine triphosphate(ATP) binding cassette transporter G2(ABCG2), and liver XOD proteins. ResultThrough network pharmacology analysis, Plantaginis Semen was selected as a candidate control herb, and Tongfengshu tablets was used as a compound compatibility environment to explore the efficacy of SFB in reducing blood uric acid levels and treating GA. Animal experiments showed that compared with the blank group, the gait score and joint swelling degree of the model group were significantly increased, and the mechanical pain threshold was significantly decreased(P<0.01). Compared with the model group, the gait score, joint swelling degree and mechanical pain threshold of rats in each medication group were improved to varying degrees. Biochemical indicators showed that compared with the blank group, the serum uric acid, creatinine, urea nitrogen and XOD levels of the model group were significantly increased(P<0.01). Compared with the model group, the serum uric acid and XOD levels of rats in each treatment group were significantly decreased(P<0.01). ELISA results showed that compared with the blank group, the levels of serum TNF-α, IL-1β and IL-6 in the model group were significantly increased(P<0.01). Compared with the model group, the levels of TNF-α, IL-1β and IL-6 in the benzbromarone group, Tongfengshu tablets group, Tongfengshu granules group and new formula group were significantly reduced(P<0.05,P<0.01). Western blot results showed that compared with the blank group, the expression levels of URAT1 and GLUT9 proteins in renal tissue and OXD protein in liver tissue of the model group were significantly increased, while the expression levels of renal OAT1 and ABCG2 were significantly decreased(P<0.01). Compared with the model group, the expression levels of renal URAT1 and GLUT9 in the SFB granules group, Tongfengshu granules group and new formula group were significantly decreased, while the expression levels of renal OAT1 and ABCG2 were significantly increased, and the expression of XOD protein in liver tissue was significantly decreased(P<0.05, P<0.01). Pathological analysis showed that focal infiltration of neutrophils, cell necrosis and nuclear fragmentation were observed in the liver tissue of the model group, sodium urate deposition crystals and tubular dilation appeared in renal tissue, synovial hyperplasia and inflammatory cell infiltration appeared in ankle joint. Compared with the model group, the abnormal degrees of liver, kidney and ankle joint tissue of rats in each treatment group were alleviated. ConclusionThe new formula of SFB replacing Plantaginis Semen has the same effect in the treatment of HUA combined with GA. This study proposes a new strategy to investigate the efficacy of new resources of Chinese medicine in a compound compatibility environment, which can provide a new demonstration for the research and development of new resources of Chinese medicine.

ObjectiveThis study explores the efficacy and pharmacological mechanism of Wujiwan in rats with inflammatory bowel disease (IBD) from the perspectives of the peroxisome proliferator-activated receptor γ (PPARγ) signaling pathway and T-cell immunity, providing reference for the treatment of IBD with traditional Chinese medicine. MethodThe study involved administering 2,4,6-trinitrobenzenesulfonic acid (TNBS) enemas to 35 rats to induce acute IBD. After 24 hours, the animals were divided into the following groups: normal group, model group, Wujiwan treatment group, and positive drug control group. Each group received gastric gavage for 8 consecutive days before the rats were dissected to compare the disease activity index (DAI) of the rat colon tissue, the colon mucosal damage index (CMDI), and the spleen index. Enzyme-linked immunosorbent assay (ELISA) was used to measure the levels of interleukin-1β (IL-1β), interleukin-10 (IL-10), and tumor necrosis factor-α (TNF-α) in the serum. Quantitative real-time polymerase chain reaction (Real-time PCR) was used to determine the mRNA expression levels of T-bet (T-box expressed in T cells) and Gata3 (Gata-binding protein-3) in the colon tissue. Western blot analysis was conducted to detect the protein expression levels of PPARγ, T-bet, and nuclear factor-κB p65 (NF-κB p65) in the rat colon. ResultThe rat model of IBD was successfully established. Compared with the model group, the Wujiwan treatment group showed reduced DAI, CMDI, and spleen index, decreased content of TNF-α in the serum(P<0.01), significantly increased content of IL-10(P<0.01), and elevated mRNA content of T-bet and Gata3(P<0.05) in the colon tissue. The expression of PPARγ protein was augmented(P<0.05), and the expression of T-bet and NF-κB p65 protein was decreased(P<0.05,P<0.01). ConclusionWujiwan activates or upregulates PPARγ expression in IBD rats to inhibit the generation of pro-inflammatory factors, participates in the inflammatory immune process, and alleviates inflammatory reactions. Its mechanism may involve regulating the NF-κB pathway through PPARγ, enhancing Th2 cell transcription expression, and reducing Th1 cell transcription.

Traditional Chinese medicine (TCM) has a long history of application in China and has consistently played a vital role in treating diseases and saving lives. TCM prescriptions (compounds) constitute the primary form of clinical TCM treatment and significantly differ from western medicine (chemicals) due to the diverse composition and chemical constituents of TCM (compounds). Nevertheless, the potential multi-component, multi-target, and multi-pathway action characteristics of TCM prescriptions also demonstrate their possible (complementary) therapeutic advantages when compared with single-component chemical drugs. Therefore, driven by the development of modern science and technology and the demands of the modernization and internationalization of TCM, modern theories regarding the complexity of TCM prescription effects have been continuously proposed: Different from the abstract language of traditional prescription theory, the modern TCM prescription theory is more inclined to illustrate the connotation of prescription compatibility concretely and vividly from an experimental and scientific perspective. In this paper, new theories on the complexity of TCM prescriptions proposed in recent years are summarized to provide research references and ideas for the greater role of TCM prescriptions and a better scientific understanding.

Objective A novel variable-diameter cortical threaded screw used in a modified cortical bone trajectory(MCBT)was designed to verify its mechanical properties using the MCBT technique.Methods According to MCBT technology,the screw pitch was fixed at 2 mm,the total length was 45 mm,the diameter of the thick rod was 5.5 mm,the diameter of the thin rod was 4.0-4.5 mm,and the length of variable-diameter position connecting the thick rod and the thin rod was 2 mm.The parameters were set based on three aspects:variable-diameter position,thread depth,and thread type.Three-factor and three-level L9 tests were conducted and screw models were established.The torsion and the bending and pull-out force of the designed screws were calculated based on the finite element method,the results were analyzed using range analysis,and then the screw models were determined.The three-dimensional(3D)model of L4 vertebral body in osteoporosis specimens was established and screws were placed according to the MCBT technique.The pull-out force of the novel variable-diameter cortical threaded screw was compared with that of a conventional non-variable-diameter cortical threaded screw.Results Range analysis showed that screw No.6(variable-diameter position:24 mm from the screw head,thread depth:0.7 mm,45° symmetrical thread)was the optimal screw.The anti-pull-out force of the No.6 variable-diameter cortical threaded screw was 13.1%higher than that of the 4.5 mm conventional non-variable-diameter cortical threaded screw,and no statistical difference in anti-pull-out force was found between the No.6 variable-diameter cortical threaded screw and the 5.5 mm conventional non-variable-diameter cortical threaded screw.Conclusions The variable-diameter position has the smallest influence on pull-out force of the screw,the thread type has the largest influence on pull-out force,and the thread depth has the largest influence on torsion and bending.Compared with that of the conventional non-variable-diameter cortical threaded screw,the variable-diameter cortical threaded screw had a smaller front end,which prevented splitting at the entrance point of the screw.The screw has a large diameter at rear end,thereby showing improved pull-out performance.The results provide a new theoretical basis for the clinical application of MCBT technology.
