Cerebral venous sinus thrombosis (CVST) is a rare type of cerebrovascular disease, accounting for about 0.5% of all strokes. About 4% of patients with CVST have supratentorial brain parenchymal lesions and brain edema sufficient to cause brain hernia and neurological deterioration, which is called malignant CVST. Malignant CVST refers to the clinical (loss of consciousness, unilateral or bilateral pupil dilation) and imaging signs of supratentorial cortical lesions (ischemia or hemorrhage) accompanied by tentorial hiatal hernia formation at the onset or after treatment with heparin. For patients with malignant CVST, decompressive craniectomy is not only a life-saving treatment, but also can make most patients achieve good functional outcome.

In recent years, the rapid increase in cancer treatment costs in China had brought a huge economic burden to society, and it was urgent to standardize the rational application of anti-tumor drugs. In the context of the reform of group payment related to disease diagnosis, a tertiary first-class hospital focused on the needs of patients and guided by value-based healthcare, established a professional and normalized refined anti-tumor drug management system, setted up a multidisciplinary diagnosis and treatment team, and promoted " Internet plus pharmaceutical services" in December 2018.From 2019 to 2021, the proportion of hospital drugs were 30.8%, 30.1%, and 27.3%, respectively. The amount of money spent on anti-tumor drugs were 83.25 million yuan, 76.41 million yuan, and 62.48 million yuan, respectively, showing a decreasing trend year by year. The practice of refined management of anti-tumor drugs fully reflected the core concept of value based healthcare, achieving closed-loop management of the entire process of drugs, improving the level of rational drug use, reducing the economic burden on patients, and providing reference for improving the level of rational use of anti-tumor drugs in public hospitals.

Objective:To observe the effect of interleukin-8 (IL-8) on the adhesion and migration of retinal vascular endothelial cells (RCEC).Methods:A cell experiment. Human RCEC (hRCEC) was divided into normal control group (N group), advanced glycation end product (AGE) treatment group (AGE group), and AGE-induced combined IL-8 antagonist SB225002 treatment group (AGE+SB group). The effect of AGE on IL-8 expression in hRCEC was observed by Western blot. The effect of SB225002 on hRCEC migration was observed by cell scratch assay. The effects of SB225002 on leukocyte adhesion and reactive oxygen species (ROS) on hRCEC were detected by flow cytometry. Student- t test was performed between the two groups. Oneway analysis of variance was performed among the three groups. Results:Compared with group N, the expression level of IL-8 in cells of AGE group was significantly increased, with statistical significance ( t=25.661, P<0.001). Compared with N group and AGE+SB group, cell mobility in AGE group was significantly increased ( F=29.776), leukocyte adhesion number was significantly increased ( F=38.159, 38.556), ROS expression level was significantly increased ( F=22.336), and the differences were statistically significant ( P<0.05). Conclusion:IL-8 antagonist SB225002 may down-regulate hRCEC adhesion and migration by inhibiting ROS expression.

Type 2 diabetes mellitus (T2DM) is a global metabolic disease with potentially life- threatening complications. Liver metabolism plays a vital role in the occurrence and development of diabetes mellitus. It has been reported that the Chinese medicinal Anemarrhenae rhizoma (AR) can relieve insulin resistance and diabetes mellitus. However, the effect on abnormal liver metabolism in diabetes mellitus is still unclear. Therefore, we extracted liver proteins of T2DM rats induced by high-fat diet (HFD) and streptozotocin (STZ), T2DM rats treated with AR extract (ARE), obesity rats (fed with HFD), and normal control rats (fed with normal diet). Then, through tandem mass tag (TMT) labeling combined with mass spectrometry (MS), we obtained the quantitative proteomic data. Bioinformatics software was used for hierarchical cluster analysis and principal component analysis of the data in each group. The volcano map for differentially expressed proteins (P < 0.05, fold change > 1.5) was plotted. It was found that the treatment group was closer to the normal control group, indicating that the quantitative proteomic data of liver tissue can reflect the therapeutic effect of ARE on T2DM rats. Key protein clusters closely related to the treatment of ARE were screened out. The Gene Ontology (GO) terms and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways of the protein clusters were analyzed by David, and the result showed that AR's alleviation of abnormal fatty acid metabolism in livers of T2DM rats may be related to the regulation of the expression of key proteins Ndufa6 and Prkar2b.

Objective: To investigate the physical and intellectual development and mutation characteristics of the phenylalanine hydroxylase (PAH) gene among 53 newborns with phenylketonuria (PKU), so as to provide insights into the management and genetic counseling of PKU Methods: The medical records of 54 children with definitive diagnosis of PKU and standardized therapy until 2 years at the Center for Neonatal Disease Screening of Shanxi Children' s Hospital from 2018 to 2021 were collected. Newborns' body weight and height developments were evaluated using the World Health Organization growth chart (2006 version), and the intellectual development was assessed using the national criteria of Development Behavior Assessment Scale among Children at Ages of 0 to 6 Years (WS/T 580-2017). The gene mutations were detected among neonates and their children, and the physical, intellectual developments and genetic characteristics of neonates with PKU were descriptively analyzed. Results: The 53 PKU cases included 29 male children and 24 female children, 36 cases with classic PKU and 17 cases with mild PKU, and 30 cases from rural areas and 23 cases from urban areas. The study subjects had a median age of 30 (10) d at initial therapy, and a mean blood phenylalanine concentration of (1 507±685) μmol/L at definitive diagnosis. There were 52 cases with normal height developments (98.11%), and all cases had normal weight and intellectual developments. The mean developmental functional quotient (DFQ) was significantly greater among urban children with PKU than among rural children [(94.92±8.57) vs. (87.65±6.57); t=-3.498, P=0.001], and the mean DFQ was significantly higher among children with mild PKU than among those with classic PKU [(95.55±8.76) vs. (88.57±7.11); t=-3.095, P=0.003]. There were 37 mutations detected in the PAH gene, which were mainly distributed in exons 3, 6, 7, 11, 12 and intron 4. Three high-frequency mutation sites were detected, including c.728G>A, c.611A>G and c.1197A>T, including three novel mutations (c.674C>G, c.1316-2A>C and c.1069T>C). Conclusions Following standardized treatment, the children with PKU have comparable physical and intellectual developments as compared to normal children. c.728G>A, c.611A>G and c.1197A>T were predominant mutations in the PAH gene among these 53 children with PKU, and three novel mutations were identified, including c.674C>G, c.1316-2A>C and c.1069T>C.

Objective:To quantitatively analyze the protein expression changes of the optic nerve in an SD rat model of non-arteritic anterior ischemic optic neuropathy (NAION), and to make bioinformatics analysis of the differential proteins.Methods:Ten 8-week-old SPF male SD rats with a body mass of 200-250 g were selected.The NAION model was established using the method of rose bengal and laser photodynamics.Four from the 8 rats with successful model were selected as the NAION model group.Another 4 body weight- and age-matched healthy SD rats without eye diseases were taken as the normal control group.The optic nerve was dissected on the 7th day after modeling.The samples were prepared by the enzyme digestion method, and the proteins were identified and quantitatively detected by isobaric tag for relative and absolute quantification labeling combined with liquid chromatography-tandem mass spectrometry.The proteins with expression fold greater than 1.5 times and significant differences between the two groups ( P<0.05) were defined as differentially expressed proteins and analyzed by bioinformatics.The use and care of animals complied with Regulations for the Administration of Affair Concerning Experimental Animals by the State Science and Technology Commission of China.The study protocol was approved by an Animal Ethical and Welfare Committee of Tianjin Medical University Eye Hospital (No.TJYY2021041029). Results:Three days after modeling, the optic disc of rats was swollen and fluorescein leakage in the optic disc was detected in fluorescein fundus angiography images in the NAION model group, which indicated the model was established successfully.A total of 1 291 quantifiable proteins including 80 differentially expressed proteins were identified.Compared with the normal control group, there were 5 up-regulated proteins and 75 down-regulated proteins.The expression levels of collagen alpha-1(V) chain (Col5A1), cAMP-dependent protein kinase catalytic subunit beta (Prkacb) and disks large homolog 1(Dlg1) were increased, and the expression levels of neurofilament medium polypeptide (Nefm), microtubule-associated protein 1B (Map1b), Ras-related protein Ral-A (Rala), serine/threonine-protein kinase N2 (Pkn2) and platelet-activating factor acetylhydrolase IB subunit beta (Pafah1b1) were decreased.Differentially expressed proteins were mainly involved in the biological processes, including regulation of the cytoskeleton, cellular response to hypoxia, axon production and extension, regulation of synapse, regulation of neuron apoptosis and axo-dendritic transport, etc.KEGG pathway enrichment analysis showed that differentially expressed proteins were mainly involved in metabolic pathways, synaptic vesicle circulation and platelet activation.Conclusions:The expression of proteins related to signal pathways such as nerve growth, energy metabolism, axo-dendritic transport and apoptosis is involved in the apoptosis of neurons in NAION.
