Objective To explore the expression and clinical significance of Yes-associated protein 1(YAP1)in esophageal squamous cell carcinoma.Methods Immunohistochemical method was used to detect YAP1 expression in 439 cases of esophageal squamous cell carcinoma.The differences of YAP1 expression and clinical parameters were analyzed between YAP1 positive group and YAP1 negative group.Kaplan-Meier curve was used to analyze the influence of YAP1 expression on survival of patients.Results The positive rate of YAP1 in esophageal squamous cell carcinoma was 30.52% .The tumor invasion was deeper in YAP1 positive group(P＜0.001).Kaplan-Meier survival analysis showed that YAP1 positive patients had longer disease-free survival(DFS)and overall survival(OS)among patients surviving longer than 30 months(P＜0.05).The multivariate Cox regression analysis showed that the invasion depth of tumor was an independent factor affecting DFS(HR=1.371,95% CI 0.993-1.894,P=0.035)and OS(HR=1.489,95% CI 1.066-2.080,P=0.020).Conclusions YAP1 has a certain percentage of positive rate in esophageal squamous cell carcinoma;for patients with survival longer than 30 months,YAP1 positive indicates a better prognosis.

Objective:To comprehensively evaluate the clinical value of Elecsys serum abnormal prothrombin (PIVKA-Ⅱ) test reagent for auxiliary diagnosis of hepatocellular carcinoma (HCC) in the Chinese population.Methods:A multicenter case-control design was used in the study. Samples from patients with first-time confirmed, diagnosed, and untreated HCC, benign liver disease and interfering controls were collected continuously. Elecsys PIVKA-II and alpha-fetoprotein (AFP) were tested for analysis. Various clinical details of the subjects were collected and analyzed. The efficacy of PIVKA-II (21.29 ng/ml) and AFP (400 ng/ml) for HCC diagnosis was calculated at specific positive cut-off values. Statistical analysis was performed using the Kruskal-Wallis test or receiver operating characteristic curve.Results:A total of 448 subjects were eventually enrolled from five centers, including 185 HCC cases. PIVKA-II had a higher diagnostic sensitivity and accuracy than AFP (84.86% vs. 30.81% and 89.01% vs. 63.66%) when the benign liver disease group was used as the control group, while the specificity was slightly lower. A sensitive analysis showed that PIVKA-II had a sensitivity of >80% at this specific positive cut-off value in the subgroup of AFP-negative subjects, patients with different etiologies, and HCC patients with multiple Barcelona Clinic liver cancer stages (including early-stage HCC). At the same time, the PIVKA-II subject had a slightly higher area under the receiver operating characteristic curve than the AFP (0.920 0 vs. 0.880 9).Conclusion:The clinical efficacy of Elecsys PIVKA-Ⅱ is good and stable in the Chinese population. Additionally, it has the clinical potential to improve the current missed diagnosis status of AFP-negative HCC and HCC monitoring at an early stage, as well as the effectiveness of accuracy promotion for HCC auxiliary diagnosis in China.

AP2 transcription factors belong to the AP2/ERF superfamily and are involved in the regula-tion of various biological processes in plant growth and development,as well as in response to biotic and abiotic stresses.However,studies on the AP2 transcription factor family of Perilla frutescens have not been reported.In this study,totally 18 AP2 family members were identified from the Perilla frutescens ge-nome and analyzed for gene structure,conserved motifs,and cis-acting elements using bioinformatics.WRINKLED1(WRI1)is a key regulator of lipid biosynthesis in many plant species and plays an impor-tant role in the regulation of lipid synthesis.Sequence comparison revealed that one member of WRI1 is highly homologous to AtWRI1 and contains two conserved AP2 domains,named PfWRI1.The expression levels of PfAP2 family genes were analyzed in different tissues of Perilla frutescens and at different stages of seed development in conjunction with the transcriptome data,and the results showed that PfWRI1 is highly expressed only in the seeds of Perilla frutescens,suggesting that PfWRI1 may be related to the de-velopmental process of the seeds.The overexpression vector of plant pCAMBIA1303-PfWRI1 was con-structed,and wild-type(Col)and mutant(wri1-1)Arabidopsis thaliana were transformed by Agrobacte-rium tumefaciens to obtain overexpression and complementation lines,respectively.The results showed that the expression of P fWRI1 led to an increase in oil content of Arabidopsis seeds by 8.90％-13.57％compared with Col,and promoted the accumulation of oleic acid(C18:1)and linoleic acid(18:2)and reduced the accumulation of palmitic acid(C16:0),arachidonic acid(C20:0),and cis-11-Eicosenoic acid(C20:1)in transgenic Arabidopsis seeds.In addition,PfWRI1 gene expression increased the ex-pression of glycolysis and fatty acid biosynthesis-related genes AtPKP-α,AtPKP-β1,AtBCCP2,AtSUS2,and AtLIP1.Taken together,PfWRI1 may promote lipid accumulation by increasing unsaturated fatty acid content through interaction with the above genes.

Objective To investigate the associations of reproductive health indicators with lung function and chronic obstructive pulmonary disease(COPD)among women aged 40 years and above.Methods From Jul to Sep,2021,female subjects aged 40 years and above were randomly selected from the Shanghai Suburban Adult Cohort and Biobank for COPD screening.A questionnaire was used to obtain information on demographic characteristics and reproductive health indicators.Linear regression was used to analyze the effects of reproductive health indicators on forced vital capacity(FVC)and forced expiratory volume in the first second(FEV1).Logistic regression was also used to analyze the effects of reproductive health factors on FVC as a percentage of the predicted value(FVC%Pred)and FEV1%Pred as well as on COPD.Results A total of 1876 women aged 40 years and above were enrolled with mean age of(62.1±8.2)years old,among them,78.1%were menopausal,and 40.9%had been pregnant≥3 times.Multivariate analysis showed that FVC and FEV1 decreased in postmenopausal women,but menopause was not associated with a decrease in their percentage of predicted values.Pregnancies≥3 times was a risk factor for COPD(for 3 times,OR=4.92,95%CI:1.48-19.95,P<0.05;for≥4 times,OR=9.06,95%CI:2.32-41.57,P<0.01),while pregnancies of 2 times did not increase the risk of COPD.Conclusion In women aged 40 years and above,menopause is associated with poorer FVC and FEV1,and excessive pregnancy(≥3 times)is a risk factor for COPD.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

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 evaluate the effects of various polysorbates(PS)on the stability of different types of monoclonal antibody(mAb)drugs.Methods Three types of monoclonal antibodies mAbA(IgG1 proantibody drug),mAbB(IgG1 mAb)and mAbC(IgG1 mAb with Fc N297A mutation)were used as model proteins,and different kinds or contents of PS were added into the mAb formulations respectively to investigate the influencing factors.The effects of PS on the stability of mAb drugs were evaluated comprehensively by detecting the changes of quality attributes,such as protein aggregates and insoluble particles.Results PS20 and PS80 showed no significant difference in inhibiting the formation of aggregates and charge variants in the three mAbs(P>0.05),while the addition of PS80 in mAbB and PS20 in mAbC significantly inhibited the increase of insoluble particles respectively(P<0.05);The content of PS20 showed a significant effect on the detection indexes of charge variants and insoluble particles in mAbC(P<0.05).Conclusion Different types of mAbs have different sensitivities to various kinds and contents of PS.Therefore,when designing the formulation of mAbs,it is necessary to select appropriate kinds and contents of PS to further improve the stability of mAb drugs.

The mesencephalic astrocyte-derived neurotrophic factor (MANF) has been recently identified as a neurotrophic factor, but its role in hepatic fibrosis is unknown. Here, we found that MANF was upregulated in the fibrotic liver tissues of the patients with chronic liver diseases and of mice treated with CCl₄. MANF deficiency in either hepatocytes or hepatic mono-macrophages, particularly in hepatic mono-macrophages, clearly exacerbated hepatic fibrosis. Myeloid-specific MANF knockout increased the population of hepatic Ly6C^high macrophages and promoted HSCs activation. Furthermore, MANF-sufficient macrophages (from WT mice) transfusion ameliorated CCl₄-induced hepatic fibrosis in myeloid cells-specific MANF knockout (MKO) mice. Mechanistically, MANF interacted with S100A8 to competitively block S100A8/A9 heterodimer formation and inhibited S100A8/A9-mediated TLR4-NF-κB signal activation. Pharmacologically, systemic administration of recombinant human MANF significantly alleviated CCl₄-induced hepatic fibrosis in both WT and hepatocytes-specific MANF knockout (HKO) mice. This study reveals a mechanism by which MANF targets S100A8/A9-TLR4 as a "brake" on the upstream of NF-κB pathway, which exerts an impact on macrophage differentiation and shed light on hepatic fibrosis treatment.
