Objective:To investigate the interactive effect of mismatch repair (MMR) protein status and adverse clinicopathological features on prognosis of stage Ⅰ-Ⅲ colon cancer.Methods:The retrospective cohort study was conducted. The clinicopathological data of 1 650 patients with colon cancer of stage Ⅰ-Ⅲ who were admitted to 7 hospitals in China from January 2016 to December 2017 were collected. There were 963 males and 687 females, aged 62(53,71)years. Patients were classified as 230 cases of MMR deficiency (dMMR) and 1 420 cases of MMR proficiency (pMMR) based on their MMR protein status. Observation indicators: (1) comparison of clinicopathological characteristics between patients of different MMR protein status; (2) analysis of factors affecting the survival outcomes of patients of dMMR; (3) analysis of factors affecting the survival outcomes of patients of pMMR; (4) interaction analysis of MMR and adverse clinicopathological features on survival outcomes. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the Mann-Whitney U test. The random forest interpolation method was used for missing values in data interpolation. Univariate analysis was conducted using the COX proportional risk regression model, and multivariate analysis was conducted using the COX stepwise regression with forward method. The coefficient of multiplication interaction effect was obtained using the interaction term coefficient of COX proportional risk regression model. Evaluation of additive interaction effects was conducted using the relative excess risk due to interaction ( RERI). Results:(1) Comparison of clinicopathological characteristics between patients of different MMR protein status. There were significant differences in age, T staging, the number of lymph node harvest, the number of lymph node harvest <12, high grade tumor between patients of dMMR and pMMR ( P<0.05). (2) Analysis of factors affecting the survival outcomes of patients of dMMR. Results of multivariate analysis showed that T staging, N staging, the number of lymph node harvest <12 were independent factors affecting the disease-free survival (DFS) of colon cancer patients of dMMR ( hazard ratio=3.548, 2.589, 6.702, 95% confidence interval as 1.460-8.620, 1.064-6.301, 1.886-23.813, P<0.05). Age and N staging were independent factors affecting the overall survival (OS) of colon cancer patients of dMMR ( hazard ratio=1.073, 10.684, 95% confidence interval as 1.021-1.126, 2.311-49.404, P<0.05). (3) Analysis of factors affecting the survival outcomes of patients of pMMR. Results of multivariate analysis showed that age, T staging, N staging, vascular tumor thrombus were independent factors affecting the DFS of colon cancer patients of pMMR ( hazard ratio=1.018, 2.214, 2.598, 1.549, 95% confidence interval as 1.006-1.030, 1.618-3.030, 1.921-3.513, 1.118-2.147, P<0.05). Age, T staging, N staging, high grade tumor were independent factors affecting the OS of colon cancer patients of pMMR ( hazard ratio=1.036, 2.080, 2.591, 1.615, 95% confidence interval as 1.020-1.052, 1.407-3.075, 1.791-3.748, 1.114-2.341, P<0.05). (4) Interaction analysis of MMR and adverse clinicopathological features on survival outcomes. Results of interaction analysis showed that the multiplication interaction effect between the number of lymph node harvest <12 and MMR protein status was significant on DFS of colon cancer patients ( hazard ratio=3.923, 95% confidence interval as 1.057-14.555, P<0.05). The additive interaction effects between age and MMR protein status, between high grade tumor and MMR protein status were significant on OS of colon cancer patients ( RERI=-0.033, -1.304, 95% confidence interval as -0.049 to -0.018, -2.462 to -0.146). Conclusions:There is an interaction between the MMR protein status and the adverse clinicopathological features (the number of lymph node harvest <12, high grade tumor) on prognosis of colon cancer patients of stage Ⅰ-Ⅲ. In patients of dMMR, the number of lymph node harvest <12 has a stronger predictive effect on poor prognosis. In patients of pMMR, the high grade tumor has a stronger predictive effect on poor prognosis.

Ketamine,an antagonist of the glutamate N-methyl-D-aspartate(NMDA)receptor,is cur-rently one of the most widely abused psychoactive substances.Prolonged abuse can result in damages to various systems in the body,making it crucial to investigate the regulatory mechanism of ketamine addic-tion and screening related biomarkers.In this study,zebrafish embryos/larvae were initially exposed a-cutely to ketamine.Then,a ketamine addiction model was established in 6-month-old zebrafish through conditioned place preference(CPP)experiments.The zebrafish brain transcriptome was analyzed using RNA-seq,while qPCR and Western blotting were employed to detect the expression of key genes.Results revealed significant reductions in the spontaneous tail coiling,embryo hatching rate,and survival rate of zebrafish embryos in the ketamine-treated group compared to the control group.The distance moved also decreased significantly,from 1904.2 mm in the control group to 319.0 mm in the high dose of ketamine group(300 μmol/L).Conditional positional preference experiments demonstrated that the control ze-brafish did not exhibit significant changes in activity in the CPP tank.In contrast,the ketamine-treated group increased their activity time in the light zone of the tank from 385.2 s before training to 706.4 s af-ter training,representing a 26.8%increase(***P<0.001).This suggests a preference for ketamine stimulation in zebrafish.KEGG analysis indicated enrichment of differentially expressed genes in the neu-roactive ligand-receptor interaction pathway in the ketamine-treated samples.GSEA analysis further re-veals a significant upregulation of the glutamatergic synapse pathway(NES=1.5).In addition,compared with the control group,the mRNA levels of Grin2b and Gria2 in the ketamine group increased by 4.6 and 1.4 times,respectively,while the protein levels increased by 2.0 and 1.4 times,respectively.These findings suggest that ketamine can induce addiction in zebrafish,potentially through upregulation of the glutamatergic synaptic pathway.

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 determine the neurotoxic effects of amyloid beta 42(Aβ42)oligomers and investigate the mechanism of their induction of Alzheimer's disease(AD)-like pathogenesis in neuronal cells.Methods Western blotting and transmission electron microscopy were used to identify the synthesized Aβ42 oligomers.In order to assess the impact of the oligomers,MTT assay was employed to measure cell viability in neuroblastoma cell line SH-SY5Y treated with 10μmol/L Aβ42 oligomers for 12 or 24 h,glutamatergic neurons derived from human embryonic stem cells(hESC)exposed to Aβ42 oligomers for 24,48,or 96 h,and corresponding control cells.TUNEL assay was utilized to assess the apoptosis of glutamatergic neurons.Additionally,immu-nofluorescence assay was applied to detect the changes in Aβ plaques and p-tau pathology.Results Western blotting displayed monomers and small-molecule aggregation(<30 000)in our synthe-sized Aβ42 oligomers,and transmission electron microscopy showed that the synthesized oligomers were mainly in a shape of spherical particles.Treatment of 10 μmol/L Aβ42 oligomers for 12 and 24 h in SH-SY5Y cells significantly decreased cell viability when compared with the control cells[(70.89±2.54)%vs(100.00±2.02)%,(52.63±3.37)%vs(100.00±2.80)%,P<0.05].The 10μmol/L oligomers treatment for 24,48 and 96 h also decreased cell viability in glutamatergic neu-rons(P<0.05).The apoptotic rates was significantly higher in glutamatergic neurons after treat-ment for 48 and 96 h when compared to the control cells[(1.44±0.31)%vs(1.00±0.38)%,(1.75±0.64)%vs(1.00±0.31)%,P<0.05].Furthermore,circular granular Aβ-positive plaque signals were observed in the glutamatergic neurons after treated with the oligomers for 24,48,and 96 h,but no such plaque signals were seen in the control cells.Additionally,glutamatergic neurons incu-bation with 10 μmol/L oligomers for 24 h resulted in tau hyperphosphorylation at the Thr231 site,with the average fluorescence intensity significantly higher than that in control cells(P<0.05).Conclusion Aβ42 oligomers show toxic effects to both SH-SY5Y cells and glutamatergic neurons,and they can also induce glutamatergic neurons to produce AD pathology.

ObjectiveRapid and accurate identification of body fluid traces at crime scenes is crucial for case investigation. Leveraging the speed and sensitivity of nucleic acid detection technology based on SHERLOCK, our research focuses on developing a peripheral blood SHERLOCK-HBA detection system to detect mRNA in forensic practice. MethodsShort crRNA fragments targeting the blood-specific mRNA gene HBA were designed and screened, alongside RPA primers. Optimal RPA primers were selected based on specificity and amplification efficiency, leading to the establishment of the RPA system. The most efficient crRNA was chosen based on relative fluorescence units (RFU) generated by the Cas protein reaction, and the Cas protein reaction system was constructed to establish the SHERLOCK-HBA detection method. The RPA and Cas protein reaction systems in the SHERLOCK detection system were then individually optimized. A total of 79 samples of five body fluids were tested to evaluate the method’s ability to identify blood, with further verification through species-specific tests, sensitivity tests, mixed spots detection, aged samples, UV-irradiated samples, and actual casework samples. ResultsThe SHERLOCK reaction system for the peripheral blood-specific marker HBA was successfully established and optimized, enabling detection within 30 min. The method demonstrated a detection limit of 0.001 ng total RNA, better than FOB strip method and comparable to RT-PCR capillary electrophoresis. The system could detect target body fluids in mixed samples and identify blood in samples stored at room temperature for three years and exposed to UV radiation for 32 h. Detection of 11 casework samples showed performance comparable to RT-PCR capillary electrophoresis. ConclusionThis study presents a CRISPR/Cas-based SHERLOCK-HBA detection system capable of accurately, sensitively, and rapidly identifying blood samples. Introducing CRISPR/Cas technology to forensic body fluid identification represents a significant advancement in applying cutting-edge molecular biology techniques to forensic science.The method’s simplicity, shorter detection time, and independence from specialized equipment make it promising for rapid blood sample identification in forensic cases.

Vaccine cooperation is an important means to deal with global infectious diseases. However, the cooperation cannot be achieved overnight. Ethical dilemma is one of the obstacles that hinders vaccine cooperation. Reviewing the history, the most successful vaccine collaboration to date has been the global smallpox eradication program. In the process of eradicating smallpox, there were also many ethical dilemmas, including the international pattern of the US-Soviet hegemony, which impacted the mutual help between countries, the ethical disputes of the vaccine itself hindering solidarity and cooperation among actors, and the vaccine coercion adopted to overcome vaccine hesitancy undermining the principle of proportionality among the freedom, equality and efficacy. The ethical dilemmas of vaccine cooperation were resolved by shaping professional and scientific consensus among medical professional groups, reaching consensus on cooperation between leading countries and developing countries, and integrating local culture to improve vaccination methods. Finally, in 1980, the world successfully eradicated smallpox. The case of smallpox eradication provides us lessons for vaccine cooperation against COVID-19 and the construction of a community of common health for mankind today.

ObjectiveTo evaluate the clinical efficacy of modified Houpo Dahuangtang in moderate and severe acute respiratory distress syndrome (ARDS) patients with phlegm-heat accumulation,and monitor the pulmonary ventilation changes of patients before and after treatment by electrical impedance tomography(EIT). MethodThe 62 cases of moderate and severe ARDS patients with phlegm-heat accumulation who required mechanical ventilation in the department of intensive care unit (ICU) in Chongqing Hospital of Traditional Chinese Medicine from September 2021 to June 2022 were selected,and divided into an experimental group(31 cases)and a control group(31 cases)using a random number table. On the basis of regular Western medicine treatment,the experimental group received modified Houpo Dahuangtang and the control group received warm water by a nasogastric tube for seven days. The changes in the clinical efficacy of traditional Chinese medicine(TCM),the oxygenation index[arterial oxygen partial pressure (PaO2)/fractional inspired oxygen(FiO2),P/F],lactic acid(Lac),acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ) score,compliance,plateau pressure,gas distribution parameters monitored by EIT(Z1,Z2,Z3 and Z4),inflammatory factors[interleukin-6 (IL-6),IL-10, tumor necrosis factor-α (TNF-α) and C-reactive protein (CRP)] of both groups before and after treatment were recorded. Besides, the mechanical ventilation time, length of stay in ICU, 28-day mortality and incidence of adverse reactions(delirium,abdominal pain and diarrhea)in the two groups were also observed. ResultThere was no significant difference in the baseline indexes of patients in the two groups,and thus the two groups were comparable. After treatment for one week, the total effective rate for TCM syndromes in the experimental group was 90.30%(28/31), higher than the 67.74%(21/31)in the control group(Z=-2.415,P<0.05).Compared with the same group before treatment, the plateau pressure and Lac decreased (P<0.01)and the compliance and P/F increased (P<0.01) in experimental group, while the Lac decreased (P<0.05)and the P/F increased (P<0.05), and the compliance and plateau pressure did not change significantly in the control group. After treatment,the plateau pressure and inflammatory factors in the experimental group were lower than those in the control group(P<0.05), but the compliance and P/F in the experimental group were higher than those in the control group(P<0.05), and the gas distribution parameters Z1,Z2,Z3,Z4,Z1+Z2,and Z3+Z4 monitored by EIT in the experimental group were all higher than those in the control group (P<0.05). There was no significant difference in mechanical ventilation time, ICU hospitalization time, 28-day mortality, delirium, abdominal pain, diarrhea and other adverse reactions between the two groups. ConclusionModified Houpo Dahuangtang can significantly improve the P/F,pulmonary ventilation in gravity-dependent regions and pulmonary compliance,reduce the release of inflammatory factors in moderate and severe ARDS patients. Compared with conventional methods,EIT can timely monitor the pulmonary ventilation changes in ARDS patients,which suggests its clinical feasibility.
