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.

Objective To explore the dynamic changes and mechanisms of neurological and cognitive functions in mice with traumatic brain injury (TBI). Methods Totally 60 12⁃month⁃old Balb/ c mice were divided into control group (10 in group) and TBI group (50 in group). TBT model mice were divided into 5 subgroups according to the time of model construction, including model 1 day, model 1 day, model 3 day, model 7 day, model 14 days and model 28 days group with 10 in each group. At the 29th day of the experiment, neurological scores and step down tests were carried out. After the test, the mice were sacrificed for brains which were detected by immunohistochemistry staining, inflammatory cytokine tests and Western blotting. Results Compared with the control group, the neurological scores of mice in TBI group increased, and then decreased after the 7th day when the scores reached the peak. However, the latency of step down errors was lower than control group, and the number of step down errors was higher than control group which had no changes. Compared with the control group, the expression of lonized calcium⁃binding adapter molecule 1(IBA1), chemokine C⁃X3⁃C⁃motif ligand1 (CX3CL1), C⁃X3⁃C chemokine receptor 1(CX3CR1), NOD⁃like receptor thermal protein domain associated protein 3 (NLRP3), and phosphorylation nuclear factor(p⁃NF)⁃κB in TBI group increased and reached to the peak at the 7th day, and then started to decrease. At the same time, the levels of inflammatory cytokines interleukin⁃6(IL⁃6) and tumor necrosis factor⁃α(TNF⁃α) first increased to the peak, and then began to decrease. However, compared with the control group, the expression of amyloid β(Aβ) protein and p⁃Tau protein in the model group continued to increase at all time. Conclusion The TBI model caused continuous activation of microglia along with inflammatory response, which first increased and then decreased, resultsing in neurological scores changes. In addition, the inflammatory response may act as a promoter of Aβ protein deposition and Tau protein phosphorylation, leading to cognitive impairment in mice.

Objective To study the quality comparability of human coagulation factor Ⅷ(FⅧ)produced before and after the change of factory site.Methods A comparative study was carried out on quality quantitative indexes,related im-purities and stability data of FⅧ produced before and after the change of factory site.Results The FⅧ quantitative quality before and after the change of factory site all met the quality standard,and the related impurities including aluminum resi-due,tributyl phosphate residue,polysorbate 80 residue and PEG residue all met the quality standard.Other impurities in-cluding human fibrinogen,fibronectin,plasminogen,IgA,IgM and IgG were extremely low in content and equivalent in quality.The content of VWF(von Willebrand factor)had no obvious change before and after the change of factory site,but was significantly higher than that of other domestic manufacturers'commercial products.The results of accelerated stability and long-term stability tests showed that the titer of FⅧ fluctuated within the methodological error range,and the results all met the quality standard.Conclusion The change of factory site of FⅧ has no effect on the quality.

Objective To study the compliance and correctness of hand hygiene(HH)of staff in intensive care units(ICUs)of a tertiary first-class hospital,and provide theoretical basis for HH intervention.Methods In April 2023,staff in 17 ICUs of this hospital were performed on-site survey by infection control staff,and monitoring forms about HH compliance and correctness were filled out.Results A total of 874 HH opportunities were ob-served with the concealed observation method,501 HH opportunities were implemented,the compliance rate was 57.32％,273 HH opportunities were correctly implemented,with an correct rate of 54.49％.The compliance and correct rate of HH among staff in different ICUs varied significantly.Compliance and correct rates of HH among staff with different jobs were statistically different:HH compliance rate of cleaners(31.97％)was lower than that of nurses(63.83％),doctors(58.77％)and other personnel(58.14％);HH correct rate of cleaners(30.77％)was lower than that of nurses(58.17％).The causes for not implementing HH among staff with different jobs and at different HH opportunities were statistically different:the rate of not implementing any HH measures after con-tact with patients(84.75％)was higher than before contact with patients(41.27％),before clean and sterile ma-nipulation(30.00％),as well as after contact with blood and body fluid(45.45％).The rate of not implementing any HH measures after contact with the patient's surrounding environment(66.67％)was higher than before con-tact with patient as well as before clean and sterile manipulation.The rates of incomplete HH steps and insufficient HH time among staff with different jobs were statistically different:The rates of incomplete HH steps of other per-sonnel(82.35％)was higher than that of doctors(52.63％).The rates of insufficient HH time of doctors(82.46％)and nurses(78.18％)were higher than that of cleaners(51.85％).Conclusion The implementation of HH among different occupational groups and at different HH implementation opportunities in ICU is significantly different,which should be intervened based on their characteristics.

Objective:To investigate the diagnostic accuracy of serological indicators and evaluate the diagnostic value of a new established combined serological model on identifying the minimal hepatic encephalopathy (MHE) in patients with compensated cirrhosis.Methods:This prospective multicenter study enrolled 263 compensated cirrhotic patients from 23 hospitals in 15 provinces, autonomous regions and municipalities of China between October 2021 and August 2022. Clinical data and laboratory test results were collected, and the model for end-stage liver disease (MELD) score was calculated. Ammonia level was corrected to the upper limit of normal (AMM-ULN) by the baseline blood ammonia measurements/upper limit of the normal reference value. MHE was diagnosed by combined abnormal number connection test-A and abnormal digit symbol test as suggested by Guidelines on the management of hepatic encephalopathy in cirrhosis. The patients were randomly divided (7∶3) into training set ( n=185) and validation set ( n=78) based on caret package of R language. Logistic regression was used to establish a combined model of MHE diagnosis. The diagnostic performance was evaluated by the area under the curve (AUC) of receiver operating characteristic curve, Hosmer-Lemeshow test and calibration curve. The internal verification was carried out by the Bootstrap method ( n=200). AUC comparisons were achieved using the Delong test. Results:In the training set, prevalence of MHE was 37.8% (70/185). There were statistically significant differences in AMM-ULN, albumin, platelet, alkaline phosphatase, international normalized ratio, MELD score and education between non-MHE group and MHE group (all P<0.05). Multivariate Logistic regression analysis showed that AMM-ULN [odds ratio ( OR)=1.78, 95% confidence interval ( CI) 1.05-3.14, P=0.038] and MELD score ( OR=1.11, 95% CI 1.04-1.20, P=0.002) were independent risk factors for MHE, and the AUC for predicting MHE were 0.663, 0.625, respectively. Compared with the use of blood AMM-ULN and MELD score alone, the AUC of the combined model of AMM-ULN, MELD score and education exhibited better predictive performance in determining the presence of MHE was 0.755, the specificity and sensitivity was 85.2% and 55.7%, respectively. Hosmer-Lemeshow test and calibration curve showed that the model had good calibration ( P=0.733). The AUC for internal validation of the combined model for diagnosing MHE was 0.752. In the validation set, the AUC of the combined model for diagnosing MHE was 0.794, and Hosmer-Lemeshow test showed good calibration ( P=0.841). Conclusion:Use of the combined model including AMM-ULN, MELD score and education could improve the predictive efficiency of MHE among patients with compensated cirrhosis.

OBJECTIVE To explore the pharmaceutical care model for elderly patients with drug-related problems （DRPs） based on the comprehensive medication management review （CMMR）， and to observe the effect of pharmaceutical care under the model. METHODS The pharmaceutical care new model for elderly patients was established by concerning CMMR guidelines in Australia. In other words， clinical pharmacists receive medical care through referral by health practitioners and active consultation by patients or their caregivers. Visits were made by a combination of face-to-face and telephone interviews. Follow-up was carried out in the form of outpatient follow-up， telephone follow-up， appointment， and home guidance to know about the treatment of DRPs by healthcare practitioners or patients.Under this model， the occurrence status and classification of DRPs in elderly patients were studied through cross-sectional investigation. The effect of pharmaceutical care was evaluated from the aspects of hospitalization rate， adverse drug reaction （ADR） incidence，medication compliance， the number of medications， blood lipid level， etc.， through self-before-after comparison. RESULTS In this study， a patient-centered， evaluation-intervention-reevaluation closed-loop pharmaceutical care model was formed. Among 317 study subjects， the average number of DRPs was 1.03 （0-7） cases. Compared before and after the intervention， the number of drug types increased from 2.00（0.00，3.00） to 2.00（1.00，3.00）， but the level of low-density lipoprotein cholesterin in patients decreased from 3.48 （2.58， 4.29） mmol/L to 3.11 （2.29，3.81） mmol/L （P＜0.05）. There was no statistical significance in hospitalization rate， ADR incidence within or medication compliance. CONCLUSIONS CMMR-based pharmaceutical care model can effectively identify and manage the patients’ DRPs and reduce the level of blood lipid.

AIM:To explore the effect of intravitreal injection FasL inhibitors on corneal apoptosis, Fas, FasL expression, Treg numbers in blood and lymph nodes and rejection index in rats after corneal transplantation.METHODS:A total of 24 SD rats(24 eyes)who received penetrating keratoplasty were randomly divided into two groups: PBS group received intravitreal injection of PBS(12 rats, 12 eyes)and FasL inhibitor group(12 rats, 12 eyes). Rejection index was recorded every week and blood samples and lymph node were collected at 1, 3 and 5wk after surgery to analyze the proportions of Treg. Corneal tissue was collected for detecting the expression of Fas and FasL and number of apoptosis.RESULTS: The expression of Fas, FasL in FasL inhibitor group decreased significantly compared with the PBS group(all P<0.05); Corneal cell apoptosis significantly decreased in FasL inhibitor group, and it was the lowest at 5wk after surgery; Treg numbers in blood and lymph nodes significantly increased in FasL inhibitor group at 3wk after surgery(all P<0.05); rejection index of corneal transplantation in the FasL inhibitor group was significantly lower than that of PBS group(all P<0.05).CONCLUSION:Intravitreal injection of FasL inhibitors after corneal transplantation could reduce the apoptosis in all layers of cornea, increase the number of Tregs in blood and lymph nodes, and alleviate rejection.

Traditional microtubule inhibitors fail to significantly enhance the effect of colorectal cancer;hence,new and efficient strategies are necessary.In this study,a supramolecular nanoreactor(DOC@TA-Fe3+)based on tannic acid(TA),iron ion(Fe3+),and docetaxel(DOC)with microtubule inhibition,reactive oxygen species(ROS)generation,and glutathione peroxidase 4(GPX4)inhibition,is prepared for ferroptosis/apoptosis treatment.After internalization by CT26 cells,the DOC@TA-Fe3+nanoreactor escapes from the lysosomes to release payloads.The subsequent Fe3+/Fe2+conversion mediated by TA reducibility can trigger the Fenton reaction to enhance the ROS concentration.Additionally,Fe3+can consume gluta-thione to repress the activity of GPX4 to induce ferroptosis.Meanwhile,the released DOC controls microtubule dynamics to activate the apoptosis pathway.The superior in vivo antitumor efficacy of DOC@TA-Fe3+nanoreactor in terms of tumor growth inhibition and improved survival is verified in CT26 tumor-bearing mouse model.Therefore,the nanoreactor can act as an effective apoptosis and ferroptosis inducer for application in colorectal cancer therapy.
