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 analyze the therapeutic effect of 3D printing technology combined with locking plate fixation on femoral shaft fracture in patients with femoral deformity.Methods:The clinical data of 33 patients with femoral shaft fracture with femoral deformity who met the inclusion criteria and underwent locking plate fixation in the Xi′an Honghui Hospital Affiliated to Xi′an Jiaotong University from June 2014 to December 2020 were retrospectively analyzed. The patients were divided into 3D printing group ( n=18) and control group ( n=15) according to whether 3D printing was performed before operation. The 3D printing group including 11 males and 7 females with an age of (46.78±13.76) years.The control group including 9 males and 6 females with an age of (48.20±14.27) years.The operation time, intraoperative blood loss, fracture healing time and complications of the two groups were recorded. Visual analogue scale (VAS) scores of pain were evaluated before and 6, 12, 24, 48 and 72 h after operation. According to the Harris hip score, the Hospital for Special Surgery (HSS) knee score and The MOS 36-item short-from Health Survey (SF-36), the hip and knee function and quality of life of the patients before and 12 months after injury were evaluated. The measurement data were represented as mean±standard deviation( ± s), and the comparison between groups was conducted using the t-test; the comparison of count data between groups was conducted by Chi-square test or Fisher exact probability. Results:The operation time, intraoperative blood loss, and incidence of complications in the 3D printing group were (91.50±9.07) min, (191.11±16.01) mL, and 0(0/18), respectively, and those in the control group were (118.07±14.19) min, (270.27±17.59) mL, and 26.7% (4/15), the differences between the two groups were statistically significant ( P <0.05). The pain VAS scores of the 3D printing group were significantly better than those of the control group at 6, 12, 24, 48, and 72 h after operation ( P<0.05). There were no differences in fracture healing time and preoperative pain VAS between the two groups( P>0.05). There were no significant differences in hip function, knee function and quality of life scores between the two groups before injury and 12 months after injury( P>0.05). Conclusion:In the treatment of femoral shaft fractures in patients with femoral deformity with locking plate fixation, the application of 3D printing technology can be used for preoperative design and plate preshaping, which can shorten the operation time, reduce the amount of intraoperative blood loss, reduce the VAS of pain and the incidence of complications, improve the satisfaction of surgery, and provide a new option for the treatment of femoral shaft fractures in patients with femoral deformity.

Objective:To investigate the clinical effects of antibiotic-loaded calcium sulfate-autologous iliac bone combined with sural neurocutaneous flap in the one-stage treatment of chronic calcaneus osteomyelitis plus skin and soft tissue defects.Methods:From January 2013 to September 2019, 48 patients were admitted to Department of Orthopedic Trauma, Xi'an Honghui Hospital Affiliated to Xi'an Jiaotong University for chronic calcaneal osteomyelitis complicated with skin and soft tissue defects. They were divided into 2 groups according to different bone grafts. In group A of 26 patients treated at one stage by antibiotic-loaded calcium sulfate-autologous iliac bone combined with sural neurocutaneous flap, there were 16 males and 10 females with an age of (45.0±11.7) years and an area of skin defect of (56.0±16.7) cm 2. In group B of 22 patients treated at one stage by simple autologous iliac bone combined with sural neurocutaneous flap, there were 13 males and 9 females with an age of (43.6±9.6) years and an area of skin defect of (53.8±16.2) cm 2. The volume of the ilium harvested, fracture healing time, infection control, donor site complications, pain score of visual analogue scale (VAS) and function recovery of the ankle were compared between the 2 groups. Results:There was no significant difference in the preoperative general data between the 2 groups, showing comparability ( P>0.05). The 48 patients were followed up for (15.3±6.0) months. Group A had a significantly smaller volume of the ilium harvested [(67.3±14.1) cm 3] than group B [(90.7±23.5) cm 3], a significantly lower rate of donor site complications [3.8% (1/26)] than group B [31.8% (7/22)], significantly lower VAS pain scores at 6, 12, 24, 48 and 72 hours than group B, and significantly lower WBC count, erythrocyte sedimentation rate and C-reactive protein at 2, 4, 8 weeks after operation than group B (all P<0.05). There was no statistically significant difference between the 2 groups in the infection control rate [96.2% (25/26) versus 77.3% (17/22)], the fracture healing time [(6.2±1.9) months versus (6.4±2.1) months], or the ankle-hindfoot score of AOFAS (The American Orthopaedic Foot and Ankle Society) (83.9±7.2 versus 82.5±8.7) at 6 months after operation (all P>0.05). Conclusion:In one-stage treatment of chronic calcaneal osteomyelitis complicated with skin and soft tissue defects, compared with simple autologous iliac bone combined with sural neurocutaneous flap, antibiotic-loaded calcium sulfate-autologous iliac bone combined with sural neurocutaneous flap can reduce the volume of the ilium harvested, pain score of VAS, and incidence of donor site complications, and improve the recovery of inflammatory indicators, leading to fine clinical effects.

Terpine-4-ol is abundant in nature. As a cyclic monoterpenoid compound， terpine-4-ol is distributed in a variety of natural plants. It is the main component and the key active substance in many traditional Chinese essential oils， such as Melaleuca alba essential oil and coral ginger essential oil. Terpine-4-ol has anti-microbial， anti-tumor， insecticidal， anti-inflammatory， and other effects. It can treat cancer， as well as oral and cardiovascular diseases with great safety. In terms of antibacterial activity， terpine-4-ol can destroy bacterial cell walls， improve membrane permeability， and regulate bacterial migration， reproduction， and other related genes to inhibit bacterial activity. In terms of antifungal activity， terpine-4-ol can bind with ergosterol in fungal cell walls to cause fungal death. In terms of insecticidal activity， terpine-4-ol can inhibit Na⁺ and K⁺-ATPase activity and cause the death of the insect. In terms of anticancer activity， terpine-4-ol can regulate the expression of apoptosis-related proteins in cancer cells， so as to control the apoptosis of cancer cells. In this paper， the pharmacological activity and action mechanism of terpine-4-ol were reviewed to provide a reference for further research and utilization of terpine-4-ol.

The rise of nanotechnology has opened new horizons for cancer immunotherapy. However, most nanovaccines fabricated with nanomaterials suffer from carrier-related concerns, including low drug loading capacity, unpredictable metabolism, and potential systemic toxicity, which bring obstacles for their clinical translation. Herein, we developed an antigen self-assembled nanovaccine, which was resulted from a simple acryloyl modification of the antigen to induce self-assembly. Furthermore, a dendritic cell targeting head mannose monomer and a mevalonate pathway inhibitor zoledronic acid (Zol) were integrated or absorbed onto the nanoparticles (denoted as MEAO-Z) to intensify the immune response. The synthesized nanovaccine with a diameter of around 70 nm showed successful lymph node transportation, high dendritic cell internalization, promoted costimulatory molecule expression, and preferable antigen cross-presentation. In virtue of the above superiorities, MEAO-Z induced remarkably higher titers of serum antibody, stronger cytotoxic T lymphocyte immune responses and IFN-γ secretion than free antigen and adjuvants. In vivo, MEAO-Z significantly suppressed EG7-OVA tumor growth and prolonged the survival time of tumor-bearing mice. These results indicated the translation promise of our self-assembled nanovaccine for immune potentiation and cancer immunotherapy.

COVID-19 has been prevalent for three years. The virulence of SARS-CoV-2 is weaken as it mutates continuously. However, elderly patients, especially those with underlying diseases, are still at high risk of developing severe infections. With the continuous study of the molecular structure and pathogenic mechanism of SARS-CoV-2, antiviral drugs for COVID-19 have been successively marketed, and these anti-SARS-CoV-2 drugs can effectively reduce the severe rate and mortality of elderly patients. This article reviews the mechanism, clinical medication regimens, drug interactions and adverse reactions of five small molecule antiviral drugs currently approved for marketing in China, so as to provide advice for the clinical rational use of anti-SARS-CoV-2 in the elderly.

Clinical efficacy is the basis for the development of traditional Chinese medicine(TCM), and the evaluation of clinical efficacy of TCM has always been the focus of attention. The technical and methodological difficulties in the evaluation process often restrict the generation of high-level evidence. Therefore, methodological research should be deepened and innovative practice should be carried out to study the application of scientific research methods in the evaluation of the advantages of TCM. After more than ten years of development, the clinical efficacy evaluation of TCM, on the basis of the initially classic placebo randomized controlled trials, has successively carried out a series of meaningful attempts and explorations in N-of-1 trials, cohort studies, case-control studies, cross-sectional studies, real world studies, narrative medicine studies, systematic evaluation, and other aspects, laying the foundation for the transformation of TCM from "experience" to "evidence". This paper focused on the clinical efficacy evaluation of TCM, summarized the main connotation and development status of efficacy evaluation indicators, standards, and methods, and put forward corresponding countermeasures and suggestions for the problems of indicator selection, standard formulation, and methodology optimization in the research process. It is clear that scientific and objective evaluation of the efficacy of TCM is an urgent problem to be solved at present.

Amid the modernization and internationalization of traditional Chinese medicine(TCM), the safety of TCM has attracted much attention. At the moment, the government, scientific research teams, and pharmaceutical enterprises have made great efforts to explore methods and techniques for clinical safety evaluation of TCM. Although considerable achievements have been made, there are still many problems, such as the non-standard terms of adverse reactions of TCM, unclear evaluation indicators, unreasonable judgment methods, lack of evaluation models, out-of-date evaluation standards, and unsound reporting systems. Therefore, it is urgent to further deepen the research mode and method of clinical safety evaluation of TCM. Based on the current national requirements for the life-cycle management of drugs, this study focused on the problems in the five dimensions of clinical safety evaluation of TCM, including normative terms, evaluation modes, judgment methods, evaluation standards, and reporting systems, and proposed suggestions on the development of a life-cycle clinical safety evaluation method that conformed to the characteristics of TCM, hoping to provide a reference for future research.
