Quality control is a key link in the modernization process of traditional Chinese medicine(TCM). Studies have shown that the effects of active components in TCM depend on not only their chemical composition but also their suitable physical forms and states. The physical phase structures, such as micelles, vesicles, gels, and nanoparticles, can improve the solubility, delivery efficiency, and targeting precision of active components. These structures significantly enhance the pharmacological activity while reducing the toxicity and side effects, demonstrating functional activity surpassing that of active components and highlighting the key effects of "structures" on "functions" of active components. Taking the physical phase structure as a breakthrough point, this paper outlines the common types of TCM physical phase structures. Furthermore, this paper explores how to realize the quality upgrading of TCM through the precise regulation of physical phase structures based on the current applications and potential of TCM physical phase structures in processing to increase the efficacy and reduce the toxicity, compounding and decocting processes, drug delivery systems, and quality control, aiming to provide novel insights for the future quality control of TCM.

Hepatocellular carcinoma(HCC), the third leading cause of cancer-related death worldwide, is characterized by high mortality and recurrence rates. Common treatments include hepatectomy, liver transplantation, ablation therapy, interventional therapy, radiotherapy, systemic therapy, and traditional Chinese medicine(TCM). While exhibiting specific advantages, these approaches are associated with varying degrees of adverse effects. To alleviate patients' suffering and burdens, it is crucial to explore additional treatments and elucidate the pathogenesis of HCC, laying a foundation for the development of new TCM-based drugs. With emerging research on gut microbiota, it has been revealed that microbiota plays a vital role in the development of HCC by influencing intestinal barrier function, microbial metabolites, and immune regulation. TCM, with its multi-component, multi-target, and multi-pathway characteristics, has been increasingly recognized as a vital therapeutic treatment for HCC, particularly in patients at intermediate or advanced stages, by prolonging survival and improving quality of life. Recent global studies demonstrate that TCM exerts anti-HCC effects by modulating gut microbiota, restoring intestinal barrier function, regulating microbial composition and its metabolites, suppressing inflammation, and enhancing immune responses, thereby inhibiting the malignant phenotype of HCC. This review aims to elucidate the mechanisms by which gut microbiota contributes to the development and progression of HCC and highlight the regulatory effects of TCM, addressing the current gap in systematic understanding of the "TCM-gut microbiota-HCC" axis. The findings provide theoretical support for integrating TCM with western medicine in HCC treatment and promote the transition from basic research to precision clinical therapy through microbiota-targeted drug development and TCM-based interventions.

OBJECTIVE: To confirm the sequence of a null allele HLA-C*08:127N produced by a base insertion. METHODS: PCR sequence-specific oligonucleotide probe (SSOP) and PCR sequence-based typing (SBT) were used for HLA routine detection, which discovered abnormal sequence maps of HLA-C in one acute myeloid leukemia patient. The sequence of the above loci was confirmed by next generation sequencing (NGS) technology. RESULTS: The SSOP typing result showed that HLA-C locus was C*03:04, C*08:01, while the sequence was suspected to be inserted or deleted in exon 3 by SBT, and finally confirmed by NGS as C*03:04, C*08:127N. CONCLUSION When base insertion produces HLA null alleles, SBT analysis software cannot provide correct results, but NGS technology can more intuitively obtain accurate HLA typing results.

Objective: To explore the relationship between dieting and binge eating with non suicidal self-injury (NSSI) among secondary vocational school students, so as to provide a scientific basis for the development of effective interventions to prevent NSSI. Methods: From October to December 2023, 2 364 students were selected by stratified cluster random sampling method from nine secondary vocational schools in Guizhou Province to conduct a self administered questionnaire survey. Unconditional binary Logisitic regression was used to analyze the relationship between dieting, binge eating behaviours, and the co-occurrence of the two and NSSI among secondary vocational school students, and were stratified by sex. Results: The detection rate of NSSI among secondary vocational school students in Guizhou Province was 27.5%, 6.8% of secondary vocational school students reported dieting, 10.5% reported binge eating behaviour, and 2.9% showed both dieting and binge eating behaviours. The adjusted model of unconditional binary Logistic regression showed that the presence of dieting ( OR =2.37), binge eating behaviour ( OR =2.31), and the co-occurrence of both ( OR =2.60) were associated with higher risk of NSSI among secondary vocational school students; stratified analysis by gender showed that both males and females with dieting, binge eating and coexistence of dieting and binge eating behaviours were at increased risk of NSSI (females: OR =2.27, 2.26, 2.78 ; males: OR =2.15, 2.08, 2.02) ( P <0.01). Conclusions Dieting and binge eating behavior of secondary vocational school students will increase the risk of NSSI. When preventing and intervening NSSI problems of secondary vocational school students, it should pay more attention to eating habits.

ObjectiveTo explore the efficacy-driving mechanism of Danhong injection （DHI） in the treatment of stable angina pectoris （SAP） based on the composition-activity relationship of target modules and clarify the pharmacological effects of DHI. MethodAccording to the angina frequency （AF） in the Seattle Angina Questionnaire （SAQ） that was obtained in the previous clinical trial， the patients before and after DHI treatment were grouped based on efficacy. The transcriptomic data of the patients before treatment and in the best efficacy group 30 days post-treatment were selected as the data source， and then weighted gene co-expression network analysis （WGCNA） was employed to construct the co-expression network. Relevant modules in the network were identified and associated with clinical features. In addition， the On-modules （Z value below 0） were identified by Zsummary. The topological indicators such as density， centrality， and clustering coefficient were adopted to explore the dynamics of DHI efficacy at the network level and module level， respectively. In addition， the driver genes were screened by the personalized network control （PNC） algorithm. Finally， rat H9C2 cells were used to establish the model of hypoxia/reoxygenation （H/R）， which was used to confirm the potential therapeutic target of DHI for SAP and provide a scientific basis for revealing the therapeutic mechanism of DHI. ResultWe identified 19 modules in the best efficacy group of DHI for SAP， and the comparison between day 0 and day 30 revealed 12 On-modules. The changes of network topological indicators at the network and module levels confirmed the correlation between the best efficacy of DHI treatment and topological dynamics. Finally， the driver genes， Klotho and fibroblast growth factor 22 （FGF22）， in DHI treatment of SAP were verified by the H9C2 cell model of H/R. ConclusionBased on clinical transcriptome data， this study determined the composition-activity relationship of target modules of DHI for SAP， which provided a scientific basis for deciphering the efficacy-driven mechanism of DHI for SAP.

Objective To investigate the efficacy of high-resolution computed tomography (HRCT)imaging radiomics for the classification and diagnosis of rheumatoid arthritis associated interstitial lung disease(RA-ILD).Methods A total of 261 patients diagnosed with RA-ILD admitted in our hospital from January 2019 to July 2023 were recruited in this study.There were 143 cases of usual interstitial pneumonia (UIP )and 118 cases of nonspecific interstitial pneumonia (NSIP).All the patients underwent HRCT.A U-net deep learning lung segmentation model was applied to obtain HRCT images for automatic lung segmentation,and 1688 imaging histologic features were extracted from each lung segmentation. Variance thresholding,univariate feature selection,and least absolute shrinkage and selection operator (LASSO ) were used for feature dimensionality reduction step by step,and various machine learning algorithms were conducted to construct the RA-ILD diagnostic histology model.The diagnostic value of each model was compared using receiver operating characteristic (ROC)curve and area under curve (AUC),and the accuracy,sensitivity and specificity of the models were evaluated.Results Feature screening finally identified 18 best features from the HRCT images of RA-ILD patients.Statistical difference was found in the distribution of Radiomics score (Radscore)between the UIP and NSIP patients in both the training and test sets (P<0.01 ).Among the 5 imaging histology models,the support vector machine (SVM)algorithm had an AUC value of 0.943 (95％CI:0.916～0.966),a sensitivity of 0.787 and a specificity of 0.912,respectively for the training set,and an AUC value of 0.909 (95％CI:0.849～0.969),a sensitivity of 0.625 and a specificity of 0.897,respectively for the testing set.Conclusion Our constructed RA-ILD classification and diagnosis model performs well,and the model based on SVM algorithm shows the best potential in classifying and diagnosing RA-ILD.

Aim To observe the role of salvianolic acid B(Sal B)in enhancing the survival of random skin flaps and to preliminarily explore its potential mecha-nisms.Methods The appearance,degree of edema,color and hair condition of the skin flap were evaluated seven days after operation.The vascular network and blood flow of random flaps were measured by laser Doppler flow measurement.HE staining was used to detect the growth of microvessels in random flaps.The expressions of VEGF and CD34 were detected by im-munohistochemistry,the expressions of RIPK1,2 and LC3 Ⅱ were detected by immunofluorescence,and the effects of autophagy related proteins and signaling path-ways were detected by Western blot.Results The ex-perimental results showed that Sal B induced autophagy in the random skin flaps,promoted angiogenesis,and reduced oxidative stress and necrotic apoptosis,signifi-cantly increasing the survival rate of the flaps.Immu-nohistochemistry,immunofluorescence staining,and Western blot confirmed that Sal B induced autophagy in the random skin flaps by activating TFE3 protein.Conclusion Sal B can promote autophagy in cells of random skin flaps and reduce their necrotic apoptosis by activating TFE3 protein.

OBJECTIVE: To explore clinical effect of Zero-profile intervertebral fusion with cage-titanium plate in treating multilevel cervical spondylotic myelopathy. METHODS: From January 2016 to January 2020, 107 patients with multisegmental cervical spondylotic myelopathy treated by surgery were retrospectively analyzed and divided into Hybrid group and control group according to different surgical methods. There were 54 patients in Hybrid group, including 42 males and 12 females, aged from 33 to 77 years old with an average of (57.3±9.5) years old;20 patients with C₃-C₆, 27 patients with C₄-C₇ and 7 patients with C₃-C₇;Zero-profile intervertebral fusion with cage-titanium plate internal fixation was performed. There were 53 patients in control group, including 34 males and 19 females;aged from 36 to 79 years old with an average of (57.8±8.9) years old;17 patients with C₃-C₆, 27 patients with C₄-C₇, and 9 patients with C₃-C₇;titanium plate interbody fusion fixation was performed. Operation time, blood loss and complications between two groups were compared, visual analogue scale (VAS), Japanese Orthopedic Association (JOA) scores and neck disability index (NDI) were used to assess recovery of clinical symptoms;cervical lordosis (CL), cervical sagittal vertical axis (C-SVA), and T₁ slope (T₁S) were measured and compared to evaluate cervical sagittal plane parameters. RESULTS: All patients were followed up, Hybrid group was followed up for 24 to 64 months with an average of (31.7±18.4) months, and control group was followed up for 24 to 65 months with an average of (32.6±15.8) months. There was no significant difference in follow-up time between two groups (P>0.05). Operation time and blood loss in Hybrid group were less than those in control group (P<0.05). VAS, JOA score and NDI were significantly improved between two groups at the lastest follow-up (P<0.05). There were no significant difference in VAS, JOA and NDI scores between two groups before and after operation (P>0.05). CL in both two groups at 3 months and the latest follow-up after operation were significantly improved than those before operation (P<0.05), there were no significant difference between two groups in T1S and C-SVA before and after operation (P>0.05). Postoperative dysphagia occurred in 2 patients in Hybrid group and 9 patients in control group, and had statistically difference in the incidence of dysphagia between two groups (χ²=5.112, P=0.024). During the follow-up, there were no complications such as loosening, displacement or fracture of internal fixation between two groups. CONCLUSION Compared with titanium plate interbody fusion, Zero-profile intervertebral fusion combined with cage-titanium plate for the treatment of multilevel cervical spondylotic myelopathy could shorten surgical time and blood loss, reduce surgical trauma and postoperative swallowing difficulties, and is conducive to early and rapid recovery.

Objective: To investigate the outcomes including major complications and prognosis of extremely preterm infants with gestational age ≤25⁺⁶ weeks. Methods: The cross-sectional study enrolled 233 extremely preterm infants with gestational age ≤25⁺⁶ weeks who were admitted to the Department of Neonatology of Shenzhen Maternity and Child Healthcare Hospital from January 2015 to December 2021. The clinical data including perinatal factors, treatments, complications, and prognosis were extracted and analyzed. These extremely preterm infants were also grouped according to gestational age and year of admission to further analyze their survival rate, major complications, causes of death, and long-term outcomes. The comparisons between the groups were performed with Chi-square test and Kruskal-Wallis. Results: Among these 233 extremely preterm infants, 134 (57.5%) were males and 99 (42.5%) females. The gestational age was (24.6±0.9) weeks, the birth weight was 710.0 (605.0,784.5) g, and the overall survival rate was 61.8% (144/233). Among the surviving extremely preterm infants, the earliest gestational age was 22⁺² weeks and the lowest birth weight was 390 g. There were 17.6% (41/233) of extremely preterm infants had treatment withdrawn and were discharged in line with the will of guardians. Among the rest 192 extremely preterm infants managed with aggressive treatments, 14 (7.3%) died in hospital and 34 (17.7%) had treatment withdrawn later due to severe complications. Of the 192 extremely preterm infants, 144 (75.0%) survived, and the survival rate increased year by year (χ²=26.28, P<0.001) while the mortality decreased year by year (χ²=14.09, P=0.027). Among the survivors, 20.8%(30/144) had no major complications, and the incidence of complications was also negatively related with the gestational age (χ²=7.24, P=0.044), and the length of invasive ventilation was negatively related to the gestational age (χ²=29.14, P<0.001). In the group of less than 23⁺⁶ weeks, all extremely preterm infants had one or more major complications. The follow-up were completed in 122 infants and revealed that delayed motor development, language retardation, and hearing and vision impairment accounted for 17.2% (21/122), 8.2% (10/122) and 17.2% (21/122), respectively. Conclusions: Extremely preterm infants with gestational age ≤25⁺⁶ weeks are difficult to treat, but the survival rate of infants undergoing aggressive treatments increases year by year. Although the prevalence of major complications is still high, most extremely preterm infants have acceptable prognosis during follow-up.
