Liver cancer is the third leading cause of cancer-related deaths worldwide， among which hepatocellular carcinoma （HCC） accounts for approximately 90% in primary liver cancer. The advances in diagnostic and treatment tools， along with a deeper understanding of their application， are transforming the treatment modality for patients. The application of these innovations in clinical practice faces challenges and requires guidance， and related clinical practice guidelines provide the latest recommendations for the management of HCC patients and conduct a comprehensive review of related data. In the 2024 EASL guidelines， a multidisciplinary team from multiple specialties conducts a multi-parameter assessment of individual risks and benefits from the perspective of patients.

ObjectiveTo observe the effect of Weichang'an prescription-containing serum on ferroptosis of human gastric cancer cells and explore the possible mechanism. MethodsSD rats were administrated with 18， 36， 72 g·kg^-1·d^-1 Weichang'an prescription by gavage for preparation of serum samples containing different doses of Weichang'an prescription， which were then used to treat MKN-45 cells. The cell proliferation was examined by the cell counting kit-8 （CCK-8）. In addition， inhibitors of apoptosis， necroptosis， and ferroptosis were added， and the survival of the cells treated with the serum samples was observed. The fluorescent probe dichlorodihydrofluorescein diacetate （DCF-DA） and the lipid peroxidation sensor C11-BODIPY were employed to detect the intracellular levels of reactive oxygen species （ROS） and lipid peroxidation， respectively. The levels of ferrous ion （Fe²⁺）， glutathione （GSH）， and malondialdehyde （MDA） were detected by enzyme-linked immunosorbent assay （ELISA）. Real-time PCR and Western blotting were employed to determine the expression of nuclear factor erythroid 2-related factor 2 （Nrf2）， aldo-keto reductase family 1 member B1 （AKR1B1）， glutathione peroxidase 4 （GPX4）， acyl-CoA synthetase long-chain family member 4 （ACSL4）， signal transducer and activator of transcription 3 （STAT3）， and mitogen-activated protein kinase （MAPK）. ResultsCompared with the blank group， Weichang'an prescription-containing serum decreased the viability of MKN-45 cells （P<0.05， P<0.01） in a time- and dose-dependent manner. Compared with the Weichang'an prescription group， the apoptosis inhibitor+Weichang'an prescription group and the ferroptosis inhibitor+Weichang'an prescription group showed increased cell viability （P<0.05， P<0.01）. Compared with the blank group， Weichang'an prescription elevated the levels of ROS， lipid peroxidation， and intracellular Fe²⁺ and MDA （P<0.05， P<0.01） and lowered the level of GSH （P<0.05， P<0.01） in a dose-dependent manner. Compared with the blank group， Weichang'an prescription down-regulated the mRNA and protein levels of Nrf2， AKR1B1， and GPX4 （P<0.05， P<0.01） and up-regulated the mRNA and protein levels of ACSL4 （P<0.05， P<0.01） in a dose-dependent manner. Compared with the blank group， Weichang'an prescription down-regulated the protein levels of p-STAT3 and p-ERK （P<0.05， P<0.01） in a dose-dependent manner. ConclusionThe Weichang'an prescription-containing serum can promote the ferroptosis and inhibit the proliferation of MKN-45 cells by regulating the STAT3 and MAPK pathways.

Objective To understand the mortality and potential life loss due to coronary heart disease (CHD) and stroke in Wujiang District, Suzhou from 2011 to 2022, and to provide strategies and basis for the prevention and treatment of CHD and stroke. Methods We collected the data of death cases due to CHD and stroke from the death monitoring system in Suzhou from 2011 to 2022. The mortality of CHD and stroke, potential years of life lost (potential years of life lost , PYLL), average years of life lost (average years of life lost , AYLL) and potential years of life lost rate (potential years of life lost rate , PYLLR) were calculated to analyze the development trend of death and disease burden of CHD and stroke. Results From 2011 to 2022, the crude mortality of CHD was 31.91/10 million, and that of stroke was 118.93/10 million. CHD and stroke mortality rates both showed an upward trend（P＜0.05, a statistically significant trend）. From 2011 to 2022, the mortality rate of CHD and stroke in Wujiang District increased rapidly with the increase of age. From 2011 to 2022, the disease burden caused by CHD totaled 11005 person-years, with PYLLR of 1.26% and AYLL of 12.34 years per person. The PYLL caused by stroke was 13 587.5 people-years, the PYLLR was 1.55%, and the AYLL was 8.93 years per person. PYLL, PYLLR and AYLL all decreased in women（P<0.05）, with no significant change in men（P>0.05）. Conclusion From 2011 to 2022, the mortality rate of CHD and stroke in Wujiang District appeared a tendency towards a rise, effective intervention and prevention measures should be taken among elderly and male residents.

Objective: To investigate the trend in incidence and change in age at onset of lung cancer in in Wujiang District, Suzhou City, Jiangsu Province from 2012 to 2021, so as to provide a basis for strengthening targeted prevention and control of lung cancer. Methods: Data of lung cancer incidence from 2012 to 2021 were collected through the Wujiang District Tumor Follow-up Registration Information System. The crude incidence, truncated incidence for 35 to 64 years, and cumulative incidence for 0 to 74 years were calculated. Chinese population-standardized incidence, Chinese population-standardized average age at onset, and Chinese population-standardized incidence proportion were calculated using the age structure of the standard population from the Fifth National Population Census in 2000. The trend in incidence of lung cancer from 2012 to 2021 was evaluated using average annual percent change (AAPC). The trend in the Chinese population-standardized average age at onset of lung cancer from 2012 to 2021 was evaluated using a linear regression model. Results: From 2012 to 2021, the crude incidence, the Chinese population-standardized incidence and truncated incidence for 35 to 64 years of lung cancer in Wujiang District were 84.57/100 000, 37.28/100 000 and 52.10/100 000, respectively, all showing upward trends (AAPC=2.489%, 2.034% and 4.654%, all P<0.05). The cumulative incidence for 0 to 74 years was 4.48%, showing no significant trend (P>0.05). The Chinese population-standardized incidence was higher in males than in females (48.16/105 vs. 26.81/105). The Chinese population-standardized incidence of lung cancer in females showed an upward trend (AAPC=8.174%, P<0.05), while the trend in males was not statistically significant (P>0.05). The crude incidence of lung cancer showed upward trends in the total population and females aged 0-<45 years (AAPC=18.287% and 25.343%, both P<0.05) and those aged 45-<55 age group (AAPC=8.003% and 17.629%, both P<0.05). The Chinese population-standardized average age at onset of lung cancer in total population and females decreased from 67.58 and 65.48 years in 2012 to 60.15 and 54.88 years in 2021, with an average annual reduction of 0.611 and 0.964 years, respectively (both P<0.05). The Chinese population-standardized incidence proportion showed upward trends for the total population and females under 65 years (AAPC=3.879% and 4.639%, both P<0.05). No statistically significant trends were observed in the Chinese population-standardized average age at onset or incidence proportion in males (both P>0.05). Conclusions From 2012 to 2021, the incidence of lung cancer in Wujiang District showed an increasing trend and a trend toward younger onset age. Young and middle-aged females had emerged as a key target population for lung cancer prevention and control.

Objective To investigate the effects of acute sleep deprivation on the behavior and synaptic protein expression of rats.Methods Seventy healthy male Wistar rats were randomly divided into seven groups,a Control group and sleep deprivation groups(24,48,72,96,120 and 144 hours).The sleep deprivation rat model was established by the modified multiplatform water environment sleep deprivation method.Spatial learning and memory were assessed by the Morris water maze.Anxiety was assessed by the open field test.The morphology and quantity of hippocampal neurons were observed by Nissl staining.Western blot and Real-time PCR were used to determine the expression of synaptophysin(SYN),post-synaptic density protein-95(PSD-95),and brain-derived neurotrophic factor(BDNF)in rats.Results Compared with the Control group,the numbers of standing and modification were significantly increased by prolongation of the sleep deprivation time(P＜0.05).The escape latency and path length were significantly increased in 120 and 144 h groups(P＜0.05),whereas the number of platform crossings and the percentage of the target quadrant time were significantly decreased(P＜0.01)and negatively correlated to the sleep deprivation time.The expression levels of BDNF,SYN,and PSD-95 were significantly decreased with the prolongation of sleep deprivation time(P＜0.01).Conclusions With the increase in sleep deprivation time,cognitive dysfunction and anxiety gradually deteriorated,which may be related to decreases in the expression of synaptic biomarkers.

Objective:To investigate the application value of nectin-4 targeting radiotracer 68Ga-N188 in the diagnosis of pancreatic cancer. Methods:The prospective study was conducted. The clinicopathologic data of 16 patients diagnosed as pancreatic cancer on enhanced computed tomography (CT) who were admitted to the Peking University First Hospital from August to December 2022 were collected. There were 9 males and 7 females, aged (62±8)years. All patients underwent 18F-flurodeoxyglucose ( 18F-FDG) and 68Ga-N188 positron emission tomography (PET)/CT examination. Observation indicators: (1) distribution of 68Ga-N188 in different tissues and tumor primary lesion of patients; (2) expression of Nectin-4 and uptake of 68Ga-N188 in pancreatic cancer; (3) comparison of examination results between 68Ga-N188 and 18F-FDG PET/CT. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Count data were described as absolute numbers or percentages. Results:(1) Distribution of 68Ga-N188 in different tissues and tumor primary lesion of patients. Results of PET/CT examination showed that in 1 hour after injection, the maximum standard uptake value (SUVmax) and mean standard uptake value (SUVmean) of 68Ga-N188 in fat, muscle, skin, and brain tissues of 16 patients were 0.40±0.16 and 0.25±0.09, 0.68±0.20 and 0.44±0.12, 0.39±0.14 and 0.28±0.11, 0.09±0.04 and 0.05±0.02, respectively.

The tumor background ratio in tumor primary lesion based on SUVmax was 1.82±0.58. (2) Expression of Nectin-4 and uptake of 68Ga-N188 in pancreatic cancer. Results of immunohistochemical staining in 16 patients showed that there were 7 patients with high Nectin-4 expression and 9 patients with low Nectin-4 expression. Results of PET/CT examination showed that the SUVmax of 68Ga-N188 in tumor primary lesion of the 7 patients with high Nectin-4 expression and 9 patients with low Nectin-4 expression were 3.77±1.10 and 2.64±0.68, showing a significant difference between them ( t=2.64, P<0.05). The SUVmax of 18F-FDG in tumor primary lesion of the 7 patients with high Nectin-4 expression and 9 patients with low Nectin-4 expression were 6.73±3.24 and 6.43±3.45, showing no significant difference between them ( t=0.17, P>0.05). (3) Comparison of examination results between 68Ga-N188 and 18F-FDG PET/CT. Of the 16 patients, cases with positive results of tumor primary lesion on 68Ga-N188 and 18F-FDG PET/CT were 14 and 11, respectively, for the 14 pancreatic cancer patients diagnosed by postoperative histopathology. Among them, cases with positive results of tumor primary lesion on 68Ga-N188 and 18F-FDG PET/CT were 3 and 1 for the 3 pancreatic cancer patients receiving evaluation for chemotherapy. The SUVmax of 18F-FDG in tumor primary lesion of the 3 patients with chemotherapy and the 11 patients without chemotherapy were 2.80±0.69 and 6.97±2.11, showing a significant difference between them ( t=3.29, P<0.05). The SUVmax of 68Ga-N188 in tumor primary lesion of the 3 patients with chemotherapy and the 11 patients without chemotherapy were 3.38±1.12 and 2.93±0.50, showing no significant difference between them ( t=0.66, P>0.05). Cases with positive results of lymph node metastases in 68Ga-N188 and 18F-FDG PET/CT were 6 and 4, respectively, for the 6 pancreatic cancer patients diagnosed with lymph node metastases by postoperative histopathology, and the SUVmax of 68Ga-N188 and 18F-FDG in lymph node metastases were 2.25±1.12 and 4.02±1.27. Conclusion:68Ga-N188 PET/CT can be used for imaging diagnosis of tumor primary lesion and lymph node metastases of pancreatic cancer.

Objective:To retrospectively analyze the treatment status of tyrosine kinase inhibitors (TKI) in newly diagnosed patients with chronic myeloid leukemia (CML) in China.Methods:Data of chronic phase (CP) and accelerated phase (AP) CML patients diagnosed from January 2006 to December 2022 from 77 centers, ≥18 years old, and receiving initial imatinib, nilotinib, dasatinib or flumatinib-therapy within 6 months after diagnosis in China with complete data were retrospectively interrogated. The choice of initial TKI, current TKI medications, treatment switch and reasons, treatment responses and outcomes as well as the variables associated with them were analyzed.Results:6 893 patients in CP ( n=6 453, 93.6%) or AP ( n=440, 6.4%) receiving initial imatinib ( n=4 906, 71.2%), nilotinib ( n=1 157, 16.8%), dasatinib ( n=298, 4.3%) or flumatinib ( n=532, 7.2%) -therapy. With the median follow-up of 43 ( IQR 22-75) months, 1 581 (22.9%) patients switched TKI due to resistance ( n=1 055, 15.3%), intolerance ( n=248, 3.6%), pursuit of better efficacy ( n=168, 2.4%), economic or other reasons ( n=110, 1.6%). The frequency of switching TKI in AP patients was significantly-higher than that in CP patients (44.1% vs 21.5%, P<0.001), and more AP patients switched TKI due to resistance than CP patients (75.3% vs 66.1%, P=0.011). Multi-variable analyses showed that male, lower HGB concentration and ELTS intermediate/high-risk cohort were associated with lower cytogenetic and molecular responses rate and poor outcomes in CP patients; higher WBC count and initial the second-generation TKI treatment, the higher response rates; Ph + ACA at diagnosis, poor PFS. However, Sokal intermediate/high-risk cohort was only significantly-associated with lower CCyR and MMR rates and the poor PFS. Lower HGB concentration and larger spleen size were significantly-associated with the lower cytogenetic and molecular response rates in AP patients; initial the second-generation TKI treatment, the higher treatment response rates; lower PLT count, higher blasts and Ph + ACA, poorer TFS; Ph + ACA, poorer OS. Conclusion:At present, the vast majority of newly-diagnosed CML-CP or AP patients could benefit from TKI treatment in the long term with the good treatment responses and survival outcomes.

3 cases with dental implant entered into the maxillary sinus by accident during posterior maxillary dental implant surgery were reported in this work.The implants were localized by CBCT scanning and removed by endoscope assisted extraction through the refined Cald-well-Luc approach under local anesthesia.The results showed that all 3 implants were successfully removed,highlighting the efficacy of en-doscopic-assisted techniques in minimizing trauma,ensuring accurate positioning and providing a clear surgical field of vision.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To investigate the practicality of TrueFidelity deep learning reconstruction algorithm in low-dose abdominal and pelvic CT angiography (CTA).Methods:The patients who required abdominal and pelvic CTA were prospectively included at the First Affiliated Hospital of Xi′an Jiaotong University from June 2020 to March 2021. All patients underwent low-dose CTA with a tube voltage of 80 kV and smart tube current modulation (100-720 mA). Images were reconstructed using the traditional FBP, adaptive statistical iterative reconstruction with a strength of 50% (ASIR-V 50%), TrueFidelity with medium (TF-M) and high (TF-H) strength. The CT value and standard deviation (SD value) of the abdominal aorta, psoas major muscle and subcutaneous fat in the same layer were measured, signal to noise ratio (SNR) and contrast to noise ratio (CNR) were calculated. We also introduced the measurement of skewness of CT value in psoas major muscle with uniform density. The above indexes of the four groups of reconstructed images were compared. A 5-point scoring method was used to evaluate the granularity, fuzziness and beam-hardening artifacts of all images. Objective measurement indicators, such as CT values, were tested by repeated measure ANOVA with the Bonferroni post hoc test.Results:There were forty-six patients in the study. The volume CT dose index of the scan was low at (1.09±0.31)mGy. There was no significant difference in CT values of vessels and muscles between the four groups ( P>0.05), but there was a significant difference in SD value( P<0.001). The SD value of the FBP group was the largest and that of the TF-H group was the smallest. The difference between SNR and CNR was statistically significant ( P<0.001), and the overall trend was opposite to that of the SD value. There was no significant difference in the skewness between the four groups. The granularity score of the FBP group was the largest, that of the TF-H group was the smallest, and there was a significant difference among the four groups. The score of fuzziness in the TF-H group was slightly higher than that in the other three groups, but there was no significant difference. The beam-hardening artifact score of FBP and ASIR-V 50% group was the worst, and the TF-H group was the best ( P<0.001). Conclusions:Compared with FBP and ASIR-V, TrueFidelity reconstruction algorithm provides better image quality (comprehensively considering image noise, fuzziness, uniformity, and hardening artifacts) in low-dose CT scanning of abdominal and pelvic vessels, and TF-H has the best image quality.
