OBJECTIVE To systematically sort out the drugs causing drug-induced liver injury （DILI） and their relevant information， and to develop the Expert consensus on the medication catalog for drug-induced liver injury and rational drug use （hereinafter referred to as the Consensus）， so as to provide a reference for rational clinical use. METHODS Systematic searches were conducted across various literature databases， guideline retrieval websites and professional liver injury websites. Drugs identified as causing DILI from the included literature and online resources were extracted and assigned scores based on source credibility： three points for LiverTox A-class drugs and two points for B-class drugs； two points for drugs from Hepatox and guidelines； and one point for drugs from consensus and related literature sources. Drugs classified as LiverTox category A/B or with total scores ≥4 were included in the preliminary list of DILI-causing drugs. Opinions were collected and integrated from a multidisciplinary expert panel comprising 45 medical and pharmaceutical experts from 27 provinces across China through three rounds of the Delphi method （including questionnaires and discussion sessions）， and after revision， the final version of Consensus was formed. RESULTS & CONCLUSIONS This Consensus included 12 traditional Chinese medicines （TCMs） such as Polygoni Multiflori Radix and Ephedrae Herba， 151 Western medicines including amiodarone and atorvastatin， along with rational use information. For TCM， eight rational use information were included： evidence-based score， liver injury classification based on pathogenesis， liver injury classification based on biochemical abnormality pattern， clinical phenotype， laboratory examination manifestations， latency period， recovery time， and management strategies. For Western medicines， six additional items were included based on the TCM， namely liver function monitoring， discontinuation， contraindications， cautions， dose adjustments， and risk factors， totaling 14 items. This Consensus systematically compiles DILI drugs and their rational use information， which will support clinicians in enhancing the prevention， identification， and management of DILI， reducing the incidence of liver injury， and ensuring patient medication safety and efficacy.

Debates persist regarding the efficacy and safety of azvudine, particularly its real-world outcomes. This study involved patients aged ≥60 years who were admitted to 25 hospitals in mainland China with confirmed SARS-CoV-2 infection between December 1, 2022, and February 28, 2023. Efficacy outcomes were all-cause mortality during hospitalization, the proportion of patients discharged with recovery, time to nucleic acid-negative conversion (T _NANC), time to symptom improvement (T _SI), and time of hospital stay (T _HS). Safety was also assessed. Among the 5884 participants identified, 1999 received azvudine, and 1999 matched controls were included after exclusion and propensity score matching. Azvudine recipients exhibited lower all-cause mortality compared with controls in the overall population (13.3% vs. 17.1%, RR, 0.78; 95% CI, 0.67-0.90; P = 0.001) and in the severe subgroup (25.7% vs. 33.7%; RR, 0.76; 95% CI, 0.66-0.88; P < 0.001). A higher proportion of patients discharged with recovery, and a shorter T _NANC were associated with azvudine recipients, especially in the severe subgroup. The incidence of adverse events in azvudine recipients was comparable to that in the control group (2.3% vs. 1.7%, P = 0.170). In conclusion, azvudine showed efficacy and safety in older patients hospitalized with COVID-19 during the SARS-CoV-2 omicron wave in China.

BACKGROUND: The use of potentially inappropriate medications (PIMs) is a major concern for medication safety as it may entail more harm than potential benefits for older adults. This study aimed to explore the prescribing rate, healthcare utilization, and expenditure of older adults using PIMs in China. METHODS: A cross-sectional analysis was conducted using a national representative database of all medical insurance beneficiaries across China, extracting ambulatory visit records of adults aged 65 years and above between 2015 and 2017. Descriptive analysis was conducted to measure the rate of patients exposed to PIM, prescribing rate of each PIM, average annual outpatient visits per patient, average total medication costs for each visit, average annual cost of PIMs for each patient, and average annual medication costs for each patient. Generalized linear model with logit link function and binomial distribution was used to examine the adjusted associations between PIMs and independent variables. RESULTS: In total, 845,278 (33.2%) participants were identified to be exposed to at least one PIM. Patients aged 75-84 years (38.1%, 969,809/2,545,430) and ≥85 years (37.9%, 964,718/2,545,430) were more likely to be prescribed with PIMs. Beneficiaries of the Urban Employee Basic Medical Insurance (UEBMI) and living in eastern and southern regions were more frequently prescribed with PIMs. Compared with patients without PIM exposure (7.5 visits, drug cost of RMB 1545.0 Yuan), patients with PIM exposure showed higher adjusted average annual number of outpatient visits (10.7 visits, β = 3.228, 95% confidence interval [CI] = 3.196-3.261) and higher annual drug costs (RMB 2461.8 Yuan, Coef. = 916.864, 95% CI = RMB 906.292-927.436 Yuan). CONCLUSIONS The results showed that the use of PIM among older adults was common in China. This study suggests that the use of PIM could be considered as a clear target, pending multidimensional efforts, to promote rational prescribing for older adults.

Coagulase-negative Staphylococci(CoNS)are a group of gram-positive cocci incapable of producing co-agulase,which distinguishes them from Staphylococcus aureus.CoNS are widely distributed in natural environ-ment and are commonly found on skin,mucous membranes and other host-associated tissues.In recent years,CoNS have become one of the significant pathogenic factors for hospital-associated infections and have been partic-ularly prevalent among the patients with impaired immune function.Although the pathogenicity of CoNS is gener-ally considered lower than that of coagulase-positive Staphylococci,the widespread use of implanted medical de-vices and extensive use of antibiotics has led to increasingly serious problems of drug resistance,which has atta-ched great importance to the hospital.The databases such as PubMed,Embase and CNKI were retrieved to reveal the drug resistance mechanisms of CoNS,aiming to push forward the research and development of new drugs against drug-resistant bacteria and emerging diagnosis and treatment measures and provide scientific bases for sol-ving the problems of antibiotics resistance around the globe.

OBJECTIVE To investigate the improvement effects and mechanism of Xiangsha yiwei tang on gastric mucosal injury in rats with chronic atrophic gastritis （CAG）. METHODS Rats were randomly assigned into normal control group， model group， Xiangsha yiwei tang low-， medium- and high-dose groups （6， 12， 18 g/kg， calculated by crude drug）， and high-dose group of Xiangsha yiwei tang+740 Y-P [Xiangsha yiwei tang 18 g/kg+transforming growth factor β1/phosphatidyl inositol 3 kinase/ protein kinase B（TGF-β1/PI3K/Akt） pathway activator group 740 Y-P 10 mg/kg]， with 18 rats in each group. Rats in each group were administered the corresponding drugs via oral gavage or injection， once daily， for 4 consecutive weeks. Gastric mucosal blood flow， the levels of serum gastrointestinal hormones [including motilin （MTL）， gastrin （GAS）， and pepsinogen （PP）]， as well as inflammatory cytokines [including tumor necrosis factor- α （TNF- α）， interleukin-1β （IL-1β）， IL-6] in rats were measured. Pathological damage to gastric mucosal tissue was observed in rats； the apoptotic rate of gastric mucosal cells was detected. The expressions of TGF-β1/PI3K/Akt signaling pathway-related proteins and apoptosis-related proteins [including B-cell lymphoma-2 （Bcl-2） and Bcl-2-associated X protein （Bax）] in the gastric mucosal tissues of rats were assessed. RESULTS Compared with normal control group， model group had abnormal gastric mucosal tissue structure， with shedding of gastric mucosal epithelial cells， and prominent infiltration of inflammatory cells. Gastric mucosal blood flow， the serum levels of MTL， GAS， PP， and Bcl-2 protein expression were lowered significantly， while serum levels of TNF-α， IL-1β and IL-6， apoptosis rate， protein expressions of Bax and TGF-β1， the phosphorylations of PI3K and Akt were increased significantly （P＜0.05）. Compared with model group， Xiangsha yiwei decoction groups exhibited attenuated histopathological injuries in gastric mucosal tissues， reduced inflammatory cell infiltration， and significant improvements in the aforementioned quantitative parameters （P＜0.05）. Compared with high-dose group of Xiangsha yiwei tang， high-dose group of Xiangsha yiwei decoction combined with 740 Y-P exhibited significantly aggravated histopathological injuries in gastric mucosal tissues， and the aforementioned quantitative parameters were markedly reversed （P＜0.05）. CONCLUSIONS Xiangsha yiwei tang can alleviate gastric mucosal damage in CAG rats， and its mechanism of action is related to the inhibition of TGF-β1/PI3K/Akt signaling pathway.

Objective:To analyze the trend of colorectal cancer incidence and age changes in cancer registration areas of Jiangsu Province from 2009 to 2019.Methods:Based on the continuous and complete data of 16 cancer registries with qualified quality control in Jiangsu Province from 2009 to 2019, the crude incidence rate, age-standardized incidence rate by Segi World Standard Population (ASIRW), age-specific incidence rate, mean age at onset, standardized mean age at onset, standardized age-specific incidence proportion, and incidence proportion of the population over 60 years old of colorectal cancer were calculated. Joinpoint software was used to calculate the average annual percentage change (AAPC) of crude incidence rate, ASIRW, age-specific incidence rate, and incidence proportion of the population over 60 years, respectively. Birth cohort models were constructed to analyze the incidence of colorectal cancer and its trends in the population born from 1929 to 2019. Linear regression models were used to analyze the correlation between mean age at onset, standardized mean age at onset and the year of onset.Results:From 2009 to 2019, a total of 48 036 new cases of colorectal cancer were collected from 16 cancer registries in Jiangsu Province, including 27 508 males and 20 528 females. The crude incidence rate and ASIRW of colorectal cancer in Jiangsu Province increased from 19.00/100 000 and 12.32/100 000 in 2009 to 33.49/100 000 and 16.75/100 000 in 2019, respectively, showing a significant upward trend (CR: AAPC=5.99%, ASIRW: AAPC=3.54%, P<0.001). The increase of ASIRW was greater in males than that observed in females (males: AAPC=4.31%, females: AAPC=2.34%, P<0.001), and greater in rural areas than in urban areas (rural areas: AAPC=4.03%, urban areas: AAPC=3.13%, P<0.001). The incidence of people over 50 years old increased significantly by year, with the 60~69 age group exhibiting a more rapid increase ( AAPC=4.97%, P<0.05). In the birth cohort, the incidence increased rapidly in the population over 50 years with the passage of birth year, with AAPCs ranging from 1.76% to 7.05% ( P<0.05). From 2009 to 2019, the standardized mean age at onset of colorectal cancer increased by 0.10 years annually. The proportion of standardized age-specific incidence exhibited a trend of increase in older age groups, and the incidence proportion of the population over 60 years old showed a significant yearly increase ( AAPC=0.86%, P<0.001). Conclusion:From 2009 to 2019, the incidence, mean age at onset and the incidence proportion of the population over 60 years old of colorectal cancer in Jiangsu Province could exhibit a rapid upward trend. The increase is particularly pronounced in males and rural areas. Additionally, the age-specific incidence distribution reveals a trend of increase in older age groups. Therefore, targeted adjustments and comprehensive prevention measures should be strengthened.

Objective:To analyze the correlation between thymus dose-volume parameters and lymphopenia in patients with early-stage breast cancer (BC) receiving adjuvant radiotherapy (RT).Methods:Medical records of 54 patients with early-stage BC who received postoperative adjuvant RT in the Second Affiliated Hospital of Soochow University from January to December 2019 were retrospectively analyzed. Absolute lymphocyte counts (ALC) were collected at 1 month before (baseline) and weekly during RT. Lymphopenia was graded based according to the common terminology criteria for adverse events version 5.0 and nadir/baseline ALC was calculated. The thymus was delineated according to anatomical boundaries in the original RT planning system. Dosimetric parameters were obtained from the dose volume histograms. Stepwise multiple linear regression analysis was used to explore the factors associated with nadir/baseline ALC. The cutoff values of dosimetric parameters for predicting ≥grade 3 lymphopenia were obtained using the receiver operating characteristic (ROC) curve.Results:The proportion of 54 patients experiencing ≥ grade 3 lymphopenia was 38.9%. The median value of thymus volume, mean dose, V 5 Gy, V 10 Gy were 14.02 cm 3, 4.95 Gy, 36.18%, and 6.61%, respectively. Stepwise multiple linear regression analysis revealed that baseline ALC ( P=0.005), quadrant location ( P=0.005) and mean thymus dose ( P<0.001) were significantly associated with nadir/baseline ALC. ROC curve analysis indicated that the cutoff values of thymus mean dose, V 5 Gy and V 10 Gy for predicting ≥ grade 3 lymphopenia were 6.12 Gy, 35.2%, and 7.4%, respectively. Conclusions:Lymphopenia in early-stage BC patients is significantly correlated with high dosimetric parameters of the thymus during postoperative adjuvant RT. Thymus may be considered as an organ at risk during RT.
