It is believed that the occurrence and development of squamous cell carcinoma （SCC） is closely associated with inflammatory responses. The theory of fire and heat， advocated by LIU Wansu， provides significant clinical guidance for understanding the pathogenesis and treatment of SCC. Based on this theory， the pathological mechanisms and clinical characteristics of SCC at different stages were analyzed. In the precancerous and early stages， the primary pathogenesis is qi stagnation leading to internal generation of constrained heat； in post-surgery， the condition shifts to qi deficiency with latent yin fire； during the treatment phase， the pathogenesis involves accumulation of pathogenic factors， excess toxins， and severe heat toxicity； in the late stage， the main pathology is yin deficiency with toxic heat， and phlegm-stasis obstruction of the internal organs. Corresponding stage-based treatment strategies are proposed. In the early stage， regulating qi movement to dissipate constrained heat； for post-surgery， tonifying qi and raising yang to dispel latent fire； during treatment stage， clearing heat and detoxifying to eliminate cancerous toxins； and in the late stage， nourishing yin and unblocking the bowels to clear deficiency heat.

Depression is a psychiatric disorder whose main symptoms include low mood， loss of interest， anxiety， sleep disturbances， and changes in appetite. Orexin， a neuropeptide located in hypothalamic neurons， has a wide range of projections throughout the central nervous system and is involved in various behavioral modulations related to depression. This study systematically reviewed the effects of orexin and its receptor-related drugs on depression and found that orexin could exert complex regulatory effects on multiple brain regions by binding to related receptors， affecting emotions， sleep， anxiety， etc. The abnormal state of expression of plasma orexin in patients with depression was found. Exogenous orexin-A， selective orexin receptor 1 antagonists （SORA1s）， selective orexin receptor 2 antagonists （SORA2s）， and dual orexin receptor antagonists （DORAs） have demonstrated antidepressant-like effects in various animal models of depression. Among them， clinical trials involving exogenous orexin-A are relatively scarce. Drugs related to SORA1s and SORA2s， such as JNJ-61393215 and Setorexant， have made significant progress in the treatment of depression. DORAs， such as Suvorexant， Lemborexant， and Daridorexant， are primarily used to treat insomnia. Notably， Suvorexant has also shown potential in alleviating symptoms of anxiety and depression.

"Stagnation" is an important pathological state in the development and progression of malignant tumors. However， its intrinsic connection with different stages of tumor evolution has not been clearly elucidated in previous studies. Drawing on clinical practice， this paper proposes the theory of stagnant toxin， emphasizing stage-specific pathogenesis and differentiated treatment strategies for tumors based on the varying manifestations of stagnation at each phase. The theory interprets the pathogenesis of stagnant toxin across the stages of tumor development through the five elements "wood， fire， earth， metal， and water" corresponding respectively to wood stagnation in the precancerous stage， metal stagnation in the postoperative phase， fire stagnation during adjuvant therapy， earth stagnation in the progressive stage， and water stagnation in the advanced stage. Each type of stagnation reflects a distinct pathogenic mechanism， such as wood stagnation giving rise to disease， metal stagnation inducing residual symptoms， fire stagnation resulting in ulceration， earth stagnation spreading toxin transmission， and water stagnation leading to critical deterioration. Accordingly， the treatment principles include guiding wood stagnation with counterflow， dispersing metal stagnation to harmonize symptoms， venting fire stagnation to regress ulcers， depleting earth stagnation to block progression， and controlling water stagnation to preserve vitality. This theoretical framework offers a traditional Chinese medicine perspective for understanding and treating malignant tumors based on the concept of stagnant toxin.

OBJECTIVE To establish a pharmaceutical management model for infusion safety in hospitalized inpatients and ensure the safety of drug use. METHODS Our hospital established the standardized management process for infusion scheme， formulated rules for compatibility contraindications in drug combinations. In the form of embedded hospital official account, the infusion scheme and medication guidance WeChat developed by pharmacists are pushed to the mobile phone of inpatients, providing electronic medication guidance services for patients, and forming a pharmaceutical management model for infusion safety of inpatients. RESULTS Our hospital provided a total of 45 291 inpatients with pharmaceutical services including the formulation of individualized infusion scheme and WeChat push infusion scheme and medication guidance as of December 2023. After the implementation of the management model， the intervention rate of pharmacists on the compatibility contraindications in drug combination of long-term medical orders for inpatients increased from 18.25% before implementation to 90.58% （P＜0.01）， and the satisfaction rate of inpatients increased from 87.50% to 94.50% （P＜0.05）. CONCLUSIONS The pharmaceutical management model for infusion safety of hospitalized patients integrates pharmaceutical services throughout the entire process of intravenous medication treatment. Pharmacists can participate in the management of infusion usage while providing qualified finished infusion products, achieving closed-loop management of pharmaceutical services, improving the hospital’s pharmaceutical service capabilities and patient satisfaction, and providing guarantees for the safety and effectiveness of patient medication.

Purpose: This study aimed to evaluate the contrast-enhanced ultrasound with Sonazoid (Sonazoid-CEUS) features of hepatocellular carcinoma (HCC) in patients with non-alcoholic fatty liver disease (NAFLD). Methods: In this retrospective study, patients who underwent surgical resection and were histopathologically diagnosed with NAFLD or cirrhosis-related HCC were included. All patients received Sonazoid-CEUS examinations within 1 week prior to hepatic surgery. The enhancement patterns of HCC lesions were evaluated and compared between the two groups according to the current World Federation for Ultrasound in Medicine and Biology guidelines. Multivariate logistic regression analysis was used to assess the correlations between Sonazoid-CEUS enhancement patterns and clinicopathologic characteristics. Results: From March 2022 to April 2023, a total of 151 patients with HCC were included, comprising 72 with NAFLD-related HCC and 79 with hepatitis B virus (HBV) cirrhosis–related HCC. On Sonazoid-CEUS, more than half of the NAFLD-related HCCs exhibited relatively early and mild washout within 60 seconds (54.2%, 39/72), whereas most HBV cirrhosis–related HCCs displayed washout between 60 and 120 seconds (46.8%, 37/79) or after 120 seconds (39.2%, 31/79) (P<0.001). In the patients with NAFLD-related HCC, multivariate analysis revealed that international normalized ratio (odds ratio [OR], 0.002; 95% confidence interval [CI], 0.000 to 0.899; P=0.046) and poor tumor differentiation (OR, 21.930; 95% CI, 1.960 to 245.319; P=0.012) were significantly associated with washout occurring within 60 seconds. Conclusion Characteristic Sonazoid-CEUS features are useful for diagnosing HCC in patients with NAFLD.

Hepatocellular carcinoma (HCC) is a leading cause of cancer-associated death globally. Liver transplantation (LT) has emerged as a key treatment for patients with HCC, and the Milan criteria have been adopted as the cornerstone of the selection policy. To allow more patients to benefit from LT, a number of expanded criteria have been proposed, many of which use radiologic morphological characteristics with larger and more tumors as surrogates to predict outcomes. Other groups developed indices incorporating biological variables and dynamic markers of response to locoregional treatment. These expanded selection criteria achieved satisfactory results with limited liver supplies. In addition, a number of prognostic models have been developed using clinicopathological characteristics, imaging radiomics features, genetic data, and advanced techniques such as artificial intelligence. These models could improve prognostic estimation, establish surveillance strategies, and bolster long-term outcomes in patients with HCC. In this study, we reviewed the latest findings and achievements regarding the selection criteria and post-transplant prognostic models for LT in patients with HCC.

Background: s/Aims: Non-invasive models stratifying clinically significant portal hypertension (CSPH) are limited. Herein, we developed a new non-invasive model for predicting CSPH in patients with compensated cirrhosis and investigated whether carvedilol can prevent hepatic decompensation in patients with high-risk CSPH stratified using the new model. Methods: Non-invasive risk factors of CSPH were identified via systematic review and meta-analysis of studies involving patients with hepatic venous pressure gradient (HVPG). A new non-invasive model was validated for various performance aspects in three cohorts, i.e., a multicenter HVPG cohort, a follow-up cohort, and a carvediloltreating cohort. Results: In the meta-analysis with six studies (n=819), liver stiffness measurement and platelet count were identified as independent risk factors for CSPH and were used to develop the new “CSPH risk” model. In the HVPG cohort (n=151), the new model accurately predicted CSPH with cutoff values of 0 and –0.68 for ruling in and out CSPH, respectively. In the follow-up cohort (n=1,102), the cumulative incidences of decompensation events significantly differed using the cutoff values of <–0.68 (low-risk), –0.68 to 0 (medium-risk), and >0 (high-risk). In the carvediloltreated cohort, patients with high-risk CSPH treated with carvedilol (n=81) had lower rates of decompensation events than non-selective beta-blockers untreated patients with high-risk CSPH (n=613 before propensity score matching [PSM], n=162 after PSM). Conclusions Treatment with carvedilol significantly reduces the risk of hepatic decompensation in patients with high-risk CSPH stratified by the new model.
