BACKGROUND AND OBJECTIVE: Patients with glioma experience a high symptom burden and have diverse palliative care needs. However, the assessment scales used in palliative care remain non-standardized and highly heterogeneous. To evaluate the application patterns of the current scales used in palliative care for glioma, we aim to identify gaps and assess the need for disease-specific scales in glioma palliative care. METHODS: We conducted a systematic search of five databases including PubMed, Web of Science, Medline, EMBASE, and CINAHL for quantitative studies that reported scale-based assessments in glioma palliative care. We extracted data on scale characteristics, domains, frequency, and psychometric properties. Quality assessments were performed using the Cochrane ROB 2.0 and ROBINS-I tools. RESULTS: Of the 3,405 records initially identified, 72 studies were included. These studies contained 75 distinct scales that were used 193 times. Mood (21.7%), quality of life (24.4%), and supportive care needs (5.2%) assessments were the most frequently assessed items, exceeding half of all scale applications. Among the various assessment dimensions, the Distress Thermometer (DT) was the most frequently used tool for assessing mood, while the Short Form-36 Health Survey Questionnaire (SF-36) was the most frequently used tool for assessing quality of life. The Mini Mental Status Examination (MMSE) was the most common tool for cognitive assessment. Performance status (5.2%) and social support (6.8%) were underrepresented. Only three brain tumor-specific scales were identified. Caregiver-focused scales were limited and predominantly burden-oriented. CONCLUSIONS: There are significant heterogeneity, domain imbalances, and validation gaps in the current use of assessment scales for patients with glioma receiving palliative care. The scale selected for use should be comprehensive and user-friendly.

Objective To investigate the clinical efficacy and safety of facilitated percutaneous coronary intervention(PCI)with half-dose recombinant staphylokinase(r-SAK)in patients with ST-segment elevation myocardial infarction(STEMI)who are expected to undergo PCI within 120 minutes.Methods From October 2021 to August 2022,a total of 200 STEMI patients in eight centers were included and randomly assigned in a 1﹕1 ratio to either r-SAK group or control group.Patients received loading doses of aspirin and ticagrelor and intravenous heparin and were randomized to receive an intravenous bolus of either 5 mg r-SAK or normal saline prior to PCI.The outcomes were set as ST-segment resolution(STR)at 60-90 minutes after PCI,the proportion and transition of pathological Q waves on the 5th day after PCI,and the proportion of high-sensitivity cardiac troponin T(hs-cTnT)peaking within 12 hours of onset.The safety outcome was major bleeding events defined as Bleeding Academic Research Consortium(BARC)≥type 3 bleeding during hospitalization.Results Compared with the control group,the r-SAK group had a higher proportion of STR≥70%within 60-90 minutes after PCI(58.3%vs.40.3%,P=0.009);a lower proportion of pathological Q waves(59.1%vs.74.1%,P=0.040);a lower rate of Q wave progression(14.8%vs.43.2%,P＜0.001);a higher rate of Q wave disappearance(12.5%vs.3.7%,P=0.027);and a higher proportion of hs-cTnT peaking within 12 hours of symptom onset[31/40(77.5%)vs.17/33(51.5%),P=0.027].Regarding the safety outcome,no significant difference in BARC≥type 3 bleeding was found between the two groups during hospitalization(P＞0.05).Conclusions For STEMI patients who were expected to undergo primary PCI within 120 minutes of symptom onset,the facilitated PCI with half-dose r-SAK significantly increased the proportion of STR≥70%at 60-90 minutes after PCI,reduced the formation of pathological Q waves,and shortened the time to peak hs-cTnT,without increasing the risk of bleeding,which should be an alternative reperfusion strategy worthy of further study.

Objective To investigate the effects of tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)in coronary arteriosclerosis(AS)on the migration of stem cell antigen-1(Scal-1)and Nanog positive cells migration.Methods Ten atherosclerotic model mice and 10 normal mice were taken respectively,and the fresh hearts of the two groups were taken out,OCT embedding,frozen sections,HE staining and oil red O staining were performed respectively to observe the pathological changes of coronary arteries;Using immunohistochemical staining techniques,the expression changes of TNF-α,IL-6,Scal-1,and Nanog in the coronary artery wall were observed under light microscope.The ventricular tissue of 20 1-week-old mice was excised.Primary Scal-1 and Nanog positive cells were extracted using density gradient centrifugation,and these cells were purified and cultured.Immunofluorescence technology was used to identify the purity of Scal-1 and Nanog positive cells.Transwell migration experiments on passage 1(P1)cells was performed to observe the effects of different concentrations of inflammatory factors on the migration of Scal-1 and Nanog positive cells.Results The blood lipid test showed that the total cholesterol,triglycerides,and low-density lipoprotein cholesterol of the model mice were significantly higher than those of the normal control group.Histological staining showed that all the mouse models had obvious coronary atherosclerosis plaque.Immunohistochemical staining results showed that the inflammatory factor TNF-α and IL-6 in atherosclerosis region were strong positive expression,while Scal-1 and Nanog positive cells in atherosclerotic plaques increased,compared to the normal group.The positive rate of Scal-1 in P1 generation cells was about 80％,The positive rate of Nanog was approximately 91％.The Transwell experiment showed that IL-6 had no effect on cell migration at low concentrations,but had an inhibitory effect on cell migration at high concentrations;Low concentrations TNF-α promoted cell migration with 0.5 μg/L TNF-α showing the most significant effection cell migration,and exhibiting inhibitory effects inhibit at high concentrations.Conclusion TNF-α and IL-6 inflammatory factors,Scal-1 and Nanog positive cells are all involved in the occurrence and development of AS,and the appropriate concentration of inflammatory factors can enhance the migration of stem cells to the coronary atherosclerosis region.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

A dry suspension of Indigo Naturalis (IN) based on lactose-IN composite particles was designed by powder modification technology to meet the clinical needs of IN. The contact angle was used as an evaluation index to investigate the effects of the type of modifier lactose, the amount of lactose, and the co-grinding time of lactose and IN on the hydrophilicity of IN. The difference between IN before and after modification was compared through physical properties such as particle size and scanning electron microscope, as well as hydrophilic properties such as surface free energy and multiple light scattering. The optimal process of lactose-IN composite particles is as follows: after lactose is ground alone for 2 minutes, it is co-ground with IN at a ratio of 1∶1 for 6 minutes. The results of the investigation of powder properties show that the particle size d_0.9 of IN is reduced from 112.75 μm to 87.30 μm after modification. The BET and Langmuir specific surface areas decreased by 8.661 m²·g^-1 and 12.512 m²·g^-1, respectively. SEM shows that lactose is attached to the surface of modified IN (MIN); surface element analysis shows that Si, Ca, and Mg elements of MIN are smaller than IN, and O elements are larger. The infrared spectrum shows that the MIN possesses the characteristic peaks of both IN and lactose. Compared MIN with IN, the contact angle and the non-polar surface free energy decreased by 35.1° and 9.975 mJ·m^-2, respectively; the polar surface free energy and the surface free energy increased by 36.956 and 26.950 mJ·m^-2, respectively. The results of multiple light scattering showed that the light transmittance of MIN was 35% lower than that of IN, and the backscattered light intensity was increased by about 25%. Only one excipient was used to successfully prepare IN dry suspension with good wettability and suspending property, which provided a basis for the development of new preparations of IN.

The powder modification technology was used to improve the powder properties and microstructure of Dioscoreae Rhizoma extract powder, thereby solving the problem of poor solubility of Dioscoreae Rhizoma formula granules. The influence of modifier dosage and grinding time on the solubility of Dioscoreae Rhizoma extract powder was investigated with the solubility as the evaluation index, and the optimal modification process was selected. The particle size, fluidity, specific surface area, and other powder properties of Dioscoreae Rhizoma extract powder before and after modification were compared. At the same time, the changes in the microstructure before and after modification was observed by scanning electron microscope, and the modification principle was explored by combining with multi-light scatterer. The results showed that after adding lactose for powder modification, the solubility of Dioscoreae Rhizoma extract powder was significantly improved. The volume of insoluble substance in the liquid of modified Dioscoreae Rhizoma extract powder obtained by the optimal modification process was reduced from 3.8 mL to 0 mL, and the particles obtained by dry granulation of the modified powder could be completely dissolved within 2 min after being exposed to water, without affecting the content of its indicator components adenosine and allantoin. After modification, the particle size of Dioscoreae Rhizoma extract powder decreased significantly, d_(0.9) decreased from(77.55±4.57) μm to(37.91±0.42) μm, the specific surface area and porosity increased, and the hydrophilicity improved. The main mechanism of improving the solubility of Dioscoreae Rhizoma formula granules was the destruction of the "coating membrane" structure on the surface of starch granules and the dispersion of water-soluble excipients. This study introduced powder modification technology to solve the solubility problem of Dioscoreae Rhizoma formula granules, which provided data support for the improvement of product quality and technical references for the improvement of solubility of other similar varieties.

Aim To study the mechanism of the ethanol extract from Leucopaxillus giganteus (LGEE) in treating breast cancer based on network pharmacology and molecular experimental validation. Methods Some chromatographic methods were used to isolate the chemical constituents of LGEE, and their structures were elucidated based on spectral data. The antitumor activities of LGEE were determined by MTT assay. The predicted targets of LGEE were selected by TCMSP and Pharmmaper, and Genecards database was used to screen the targets. GO and KEGG analysis of target genes were performed. Molecular docking was used to test the binding of active components to core targets. Western blotting was used to validate the regulating function of chlorogenic acid on CHEK2 and CASP3 targets of MDA-MB-231 cells. Results Thirteen compounds were identified including clitocine, chlorogenic acid and so on. LGEE displayed anticancer activities against MDA-MB-231 with the inhibition percent (87. 35 ± 1. 55)%, at the concentration of 200 mg· L

Objective To investigate the structural distribution features and mechanism of elastic fibers and collagen fibers in ventricular interstitium of aged rats. Methods Five young SD rats (24 weeks) and five old SD rats (104 weeks) were used,and their cardiac function was examined by echocardiography. Modified Weigert elastic fiber staining, immunohistochemistry, immunofluorescence and Western blotting techniques were used to detect the expression changes of type I and IH collagen fibers and their proteins, elastic fibers and their proteins, matrix metalloproteinase 2 (MMP-2), matrix metalloproteinase 9 (MMP-9) and tissue inhibitor of metalloproteinase 2 (TIMP-2), respectively. Results The type I and type IH collagen in the ventricular interstitium of aged rats was very sufficient and wrapped around the cardiomyocytes. Compared with the young rats, the content of collagen protein in the ventricular interstitium of the aged rats significantly increased (P<0. 05). Elastic fibers in the ventricular interstitium of the aged rats were and widely distributed. Compared with the young rats, the number of elastic fibers and the level of elastin in the ventricular interstitium of the aged rats significantly decreased (P<0. 05), and the expression levels of MMP-2 and MMP-9 in ventricular muscle of aged rats increased, and the)' were correlated with the level of elastin. The level of TIMP-2 in ventricular muscle of aged rats decreased with age. Conclusion The number of collagen fibers and elastic fibers in ventricular interstitium of aged rats is fluctuated with each other. With the increase of age, the contents of TIMP-2 and elastic fibers in the ventricular interstitium gradually decreased, and the ratio of collagen fibers to elastic fibers is out of balance.

AIM: To investigate the protective effect of salvianolic acid B on retina and its influence on angiogenesis in retinal vein occlusion(RVO)injured rats.METHODS: SD rats were randomly divided into control group, model group and salvianolic acid B group, with 10 rats in each group. In addition to the control group, rats in model group and salvianolic acid B group were induced RVO by Bengal red combined with laser photodynamic method. The rats in salvianolic acid B group were intraperitoneally injected with salvianolic acid B 50 mg/(kg·d), while the rats in control group and model group were only given the same amount of normal saline for 21 consecutive days. Fundus fluorescein angiography(FFA)was used to observe the retinal vein structure before and after administration. HE staining was used to observe the pathological changes of rat retina. The retinal function of rats was evaluated by electroretinogram(ERG). The fluorescence expression of vascular endothelial growth factor A(VEGFA)in retina of rats in each group was detected by immunofluorescence staining. The relative expression of HIF-1α, STAT3, p-STAT3 and VEGFA proteins in retinal tissue were detected by Western blotting.RESULTS: Compared with the control group, the blood flow at the retinal obstruction in the model group was recanalized, and the effective collateral circulation was abundant, but the shape was irregular, and there was fluorescence leakage. In salvianolic acid B group, the retinal vein circulation recovered, the shape became regular gradually, and the collateral vessels decreased. The retina of the model group and salvianolic acid B group showed different degrees of pathological damage. At the same time, the amplitude of ERG a wave and b wave, the thickness of retinal total layer(RTL), inner nuclear layer(INL)and outer nuclear layer(ONL)decreased, the fluorescence intensity of VEGFA enhanced, and the relative expression of HIF-1α, p-STAT3 and VEGFA protein increased(P<0.05). Compared with the model group, the retinal histopathological damage of salvianolic acid B rats was alleviated, the amplitude of ERG a-wave and b-wave, the thickness of RTL, INL and ONL were increased, the fluorescence intensity of VEGFA was weakened, and the relative expression of HIF-1α, p-STAT3 and VEGFA proteins was decreased(P<0.05).CONCLUSION: Salvianolic acid B can alleviate the retinal histopathological injury and improve retinal function in RVO rats, which may be related to inhibiting the activation of HIF-1α/STAT3/VEGFA pathway and reducing angiogenesis.
