Conclusion:The brain networks of patients with first-episode paranoid schizophrenia may have regional dysfunction in the transmission efficiency and fault-tolerant ability of resting state brain functional network, and the abnormalities of efficiency may be associated with the severity of psychiatric symptoms in several brain regions.

Fibrosis refers to the disorder of repair response after tissue damage， which is mainly characterized by the increase of fibrous connective tissue and the decrease of parenchymal cells in organs. Progressive fibrosis can lead to the destruction of tissue structure and organ failure. Ferroptosis is a new type of programmed cell death， which is caused by the accumulation of iron dependent lipid peroxides and regulated by iron metabolism， iron autophagy， amino acid metabolism and lipid metabolism. Ferroptosis plays an important role in the pathological process of fibrosis， participating in many pathological processes such as organ parenchymal cell injury， macrophage inflammation， oxidative stress and myofibroblast transformation. Studies have shown that ferroptosis occurs in myofibroblasts during extracellular matrix deposition in the fibrous cascade reaction， and the targeted regulation of ferroptosis can effectively reduce chronic organ injury and tissue fibrosis. It has been confirmed that a variety of traditional Chinese medicine and its active components can regulate the ferroptosis parenchyma cells of organs and play an anti-fibrosis effect， showing a good research prospect. This article summarizes the role of ferroptosis in the pathological process of liver， lung， kidney and heart fibrosis and the intervention of related Chinese medicine， in order to provide a new target for Chinese medicine to prevent and treat fibrosis.

With the change in environmental pollution and lifestyle， the incidence and mortality of cancer are increasing year by year， which is a serious threat to human life and health. Autophagy is a process in which eukaryotic cells use lysosomes to degrade cytoplasmic proteins and damaged organelles under the regulation of autophagy-related genes. It plays a dynamic inhibiting or promoting role in the occurrence and development of cancer and is involved in the regulation of tumor formation， proliferation， metastasis， and response to anticancer therapy. With the deepening of the research on the mechanism of cancer， a variety of cancer treatment methods have been established， such as chemotherapy， radiotherapy， surgery， immunotherapy， and gene therapy. Pharmacological or genetic inhibition of autophagy has been shown to enhance the lethal effect of various anticancer treatments on tumor cells， suggesting that inhibition of autophagy is an effective sensitization strategy in cancer therapy. Meanwhile， over-stimulation of autophagy may also provide a new method for the treatment of drug-resistant cancer cells with high apoptotic thresholds. As a treasure of Chinese culture， traditional Chinese medicine plays an important role in the adjuvant treatment of cancer with its advantages of multi-target， multi-pathway， and small side effects. In recent years， many positive results have been achieved in the study of natural autophagy regulatory factors of traditional Chinese medicine in cancer， and they have been widely verified in different autophagy regulatory models. This article outlines the mechanism of autophagy， summarizes the dual regulatory role of autophagy in tumor biology， and collects relevant studies published in the databases of China National Knowledge Infrastructure (CNKI） and Wanfang Data for nearly 10 years that affect the role of tumorigenesis and development by regulating autophagy. The article also collates autophagy rules of tumor cells induced by traditional Chinese medicine and its active ingredients， so as to provide a certain reference for the research on the development and application of anti-tumor drugs.

OBJECTIVE: To analyze the clinical phenotype and genetic basis for a Chinese pedigree suspected for branchiootic syndrome (BOS). METHODS: The proband was subjected to target-capture high-throughput sequencing to detect potential variant of deafness-associated genes. Candidate variants were verified by Sanger sequencing of the family members. RESULTS: The proband was found to harbor a c.1627C>T (p.Gln543Ter) nonsense variant of the EYA1 gene. Sanger sequencing confirmed that all of the 4 patients with the BOS phenotype from the pedigree have harbored the same heterozygous variant. Based on the guidelines of the American College of Medical Genetics and Genomics, the variant was predicted to be pathogenic (PVS1+PS+PP3+PP4). CONCLUSION The c.1627C>T (p.Gln543Ter) variant of the EYA1 gene probably underlay the BOS phenotype in this pedigree. Above finding has provided a basis for its clinical diagnosis.

Objective:To compare the application value of Caprini thrombosis risk assessment scale and Shanghai venous thrombosis risk factor scale in predicting venous thromboembolism in hospitalized maternal patients.Methods:This was a case-control study. A total of 67 pregnant women complicated with venous thromboembolism in the Obstetrics Department of Shandong Provincial Hospital Affiliated to Shandong First Medical University from January 2010 to September 2021 were retrospectively analyzed. And 144 pregnant women without venous thromboembolism in the same period were selected. Two venous thrombosis risk assessment tools were used to evaluate the pregnant women, and the predictive effectiveness and accuracy of the two assessment tools were compared.Results:The effects of the two risk assessment tools for venous thrombosis were different before and after delivery with statistical difference ( Z=8.15, 5.97, both P<0.01), but the Shanghai venous thrombosis risk factor scale (83.9%, 67.3%) was superior to Caprini thrombosis risk assessment scale (52.1%, 45.0%) in the accuracy of prenatal and postnatal prediction. The area under receiver operating characteristic curve showed that the Shanghai venous thrombosis risk factor rating scale (0.863) was significantly superior to the Caprini thrombosis risk assessment scale (0.748) after delivery. Conclusions:The Shanghai venous thrombosis risk factor scale is more valuable than the Caprini thrombosis risk assessment scale in the early risk identification of venous thromboembolism in pregnant women.

In order to obtain polyclonal antibodies against the fibrillar(Fiber)protein of fowl ade-novirus serotype 11(FAdV-11)and investigate its cross-reactivity to different serotypes of FAdV Fiber,the gene encoding the FAdV-11 Fiber protein was cloned into a prokaryotic expression vec-tor pET-32a by homologous recombination technology,then the plasmid was transformed into BL21(DE3)receptor cells,and the purified recombinant protein was used as an immunogen to im-munize rabbits to prepare polyclonal antibody after induced expression,and the cross-reactivity of the polyclonal antibody against different serotypes of FAdV Fiber proteins was identified by West-ern blot and indirect immunofluorescence(IFA).The results showed that the His-FAdV-11-Fiber recombinant protein was mainly expressed as inclusion bodies and was well expressed.Western blot and IFA showed that the prepared polyclonal antibody reacted with the Fiber proteins of FAdV-8a,FAdV-8b,and FAdV-11,but did not with the 2 Fiber of FAdV-4(Fiber 1 and Fiber 2)proteins.In conclusion,in this study,we successfully prepared rabbit polyclonal antibodies against FAdV-11 Fiber and showed that it specifically recognized the Fiber proteins of FAdV-8a,FAdV-8b and FAdV-11,which lays the foundation for further establishment of serological differential diag-nosis of FAdV-11.

Objective:To explore the correlation between high cholinergic pathway signaling and cognitive function in patients with Parkinson disease(PD) accompanied with sleep disorder.Methods:PD patients admitted from 2017 to 2022 were divided into PD with sleep disorder group (PD-SD group) ( n=56) and PD without sleep disorder group (PD-NSD group) ( n=41) according to the Parkinson's disease sleep scale (PDSS) score. All participants underwent magnetic resonance imaging examination.All patients were evaluated by the PDSS, Hoehn-Yahr (H-Y), Montreal cognitive assessment scale (MoCA), and cholinergic pathways hyper intensities scale (CHIPS). The difference of cognitive function between the two groups and the correlation between CHIPS and cognitive function were analyzed.Independent sample t-test, Spearman correlation analysis, and binary Logistic regression analysis were performed on the data by SPSS 26.0 statistical software. Results:(1)The MoCA score of the PD-SD group (22.00 (5.00)) was lower than that of the PD-NSD group (26.00 (5.00)) ( Z=-3.830, P<0.05). The total and all aspects scores of CHIPS in PD-SD group were higher than those in PD-NSD group(the total score of the low external capsule: 12.00(8.00), 0(8.00), the total score of the high external capsule: 12.00(2.00), 6.00(9.00), the total score of the radial crown: 8.00(0), 4.00(4.00), the total score of the centrum semiovale: 3.00(4.00), 0(2.00), the total score of the right side: 16.00(9.00), 5.00(10.00), the total score of the left side: 17.00(6.00), 7.00(9.00), the total score of CHIPS: 32.00(14.00), 14.00(20.00))( Z=-5.081, -5.873, -4.933, -3.211, -5.562, -6.232, -5.995, all P<0.05). (2)The correlation analysis between the score of CHIPS and cognitive function in the PD-SD group showed that, the total score of the low external capsule ( r=-0.286), the total score of the centrum semiovale ( r=-0.307), the total score of the right side ( r=-0.376), the total score of the left side ( r=-0.284) and the total score of CHIPS ( r=-0.349) were negatively correlated with MoCA(all P<0.05). (3)Binary Logistic regression analysis showed that white matter lesions in centrum semiovale, low inner capsule, right and left leukodystrophy were not influence factors for cognitive impairment (all P>0.05). Conclusion:PD patients with sleep disorders have lower cognitive function scores, higher CHIPS scores, and significant changes in white matter lesions compared to those without sleep disorders. In PD patients with sleep disorders, the higher the CHIPS score, the lower the cognitive function score, and the more significant the rate of cognitive impairment occurrence and development.

【Objective】 To investigate the effect of leukocyte-depleted suspended red blood cells (lds-RBCs) storaged for different time on blood transfusion effect of patients with hematologic diseases and malignant tumors, as well as to evaluate the storage quality of lds-RBCs in blood stations. 【Methods】 Seven hospitals (4 tertiary-A hospitals and 3 secondary-A hospitals), applying for blood from our blood center, were selected. Blood transfusion cases (medical record) and related data (indicators) of patients with blood diseases and malignant tumors in those hospitals from December 2018 to May 2019 were collected, including disease diagnosis (type) before transfusion, demographic characteristics, date of solo transfusion of lds-RBCs, units of lds-RBCs [(1~2)U/bag, 1 U=200 mL whole blood], different storage duration (1~5 weeks) (bar code), and hemoglobin (Hb) 48 h before and after transfusion. The efficacy of lds-RBCs (storaged for different time) transfusion in patients with hematologic diseases and malignant tumors was evaluated by statistical analysis. 【Results】 A total of 3 557 patients with hematologic diseases and malignant tumors were enrolled in this study. No significant changes were noticed in transfusion efficacy by blood transfusion unit, gender and previous transfusion history (P > 0.05). The effective rate of lds-RBCs in patients with blood diseases and malignant tumors, stratified by storage duration, i. e. storaged for >1~2 weeks, >2~3 weeks, >3~4 weeks and more than >4~5 weeks, was 78.77% vs 77.68% vs 75.06% vs 70.37%, and 79.32% vs 76.73% vs 72.79% vs 67.65%, respectively(P<0.05), with lds-RBCs of 4-5 storage weeks presenting the lowest transfusion efficacy in both groups of patients. 【Conclusion】 The storage time of most lds-RBCs supplied by our center is moren than 3 weeks, and the transfusion effect of lds-RBCs stored for 5 weeks needs further observation. In order to ensure and improve the efficacy of blood transfusion, evidence-based medicine and information management are needed to help the clinical gasp the advantageous time of blood products and shorten the storage-to-transfusion time of red blood cells.
