		                        			Objective: To investigate the protective effects and underlying mechanisms of sodium pyruvate (SP) on RBC storage lesions using an oxidative damage model. Methods: Six units of leukocyte-depleted suspended RBCs (discarded for non-infectious reasons within three days post-collection) were randomly assigned to four groups: negative control (NS), positive control (PS), experimental group 1 (SP1), and experimental group 2 (SP2). Oxidative stress was induced in the PS group by the addition of hydrogen peroxide (H
      O
      ), while SP1 and SP2 received SP supplementation at different concentrations (25 mM and 50 mM, respectively) in the presence of H
      O
      . After 1 hour of incubation, RBC morphology was assessed microscopically, and biochemical indicators including glutathione (GSH), malondialdehyde (MDA), methemoglobin (MetHb), adenosine triphosphate (ATP), and Na
      /K
      -ATPase activity were measured. Results: RBCs in the PS group exhibited pronounced morphological damage, including cell shrinkage and echinocyte formation, whereas both SP-treated groups showed significantly reduced structural injury. SP treatment led to elevated GSH levels and decreased concentrations of MDA and MetHb, suggesting attenuation of oxidative stress. Additionally, SP enhanced intracellular ATP levels and Na
      /K
      -ATPase activity, thereby contributing to membrane stability. Notably, the SP2 group (50 mM) demonstrated superior protective effects compared to SP1 (25 mM). Conclusion: Sodium pyruvate effectively attenuates oxidative storage lesions in RBCs, primarily through its antioxidant properties, energy metabolism supporting ability, and celluar membrane stabilizing function. These findings suggest SP as a promising additive for enhancing the quality and safety of stored RBCs.

MethodsThe Enterobacteriaceae strains carrying mcr⁃1 resistance gene isolate from inlet of WWTP during April 1 to June 30, 2023 in Shanghai were cultured on blood-rich and SS culture medium and were identified using a mass spectrometry analyzer. The mcr⁃1 gene and copy number were detected by real-time fluorescence quantitative PCR. Drug susceptibility test was performed by microbroth dilution method. The copy numbers of Escherichia coli carrying mcr⁃1 gene isolated from wastewater and human fecel were statistically analyzed by SPSS 25.0. ResultsA total of 14 strains carrying the mcr⁃1 gene were isolated from 49 WWTP samples, and the positive isolation rate was 28.6%, including 12 non-diarrheal E. coli strains and 2 Klebsiella pneumoniae strains. The drug susceptibility results showed that all 14 strains were multi-drug resistant bacteria. They were all sensitive to imipenem and tigecycline, but were ampicillin- and cefazolin-resistant. There was no significant difference in the copy number between human-sourced diarrheal E. coli and wastewater-sourced non-diarrheal E. coli (t=0.647, P>0.05). ConclusionThe isolation and identification of strains carrying the mcr⁃1 gene from inlet of WWTP samples were firstly established in Shanghai. The multi-drug resistance among the isolated strains is severe. To effectively prevent and control the spread of colistin-resistant bacteria, more attention should be paid to the surveillance of mcr⁃1 gene.

		                        			Tumor cells use glycolysis to provide material and energy under hypoxic conditions to meet the energy requirements for rapid growth and proliferation, namely the Warburg effect. Even under aerobic conditions, tumor cells mainly rely on glycolysis to provide energy. Therefore, glucose transporter protein 1(GLUT1), which is involved in the process of glucose metabolism, plays an important role in tumorigenesis, development and drug resistance, and is considered to be one of the important targets in the treatment of malignant tumors. In recent years, research on tumor glucose metabolism has gradually become a hot spot. It has been shown that various factors are involved in the regulation of tumor energy metabolism, among which the role of GLUT1 is the most critical. In this paper, the authors reviewed the latest research progress of GLUT1-targeted traditional Chinese medicine(TCM) active ingredient nano-delivery system in tumor therapy, aiming to reveal the feasibility and effectiveness of this system in the delivery of chemotherapeutic drugs. The GLUT1-targeted TCM active ingredient nano-delivery system can overcome the bottleneck of the traditional targeting strategy as well as the high-permeability long retention(EPR) effect. In summary, the authors believe that the GLUT1-targeted TCM active ingredient nano-delivery system provides a new strategy for targeted treatment of tumors and has a broad application prospect in tumor prevention and treatment.

		                        			 AIM: To observe the changes of nerve fiber thickness and vessel density in macula and optic disc following femtosecond laser-assisted and conventional phacoemulsification cataract surgery through optical coherence tomography angiography(OCTA).METHODS: A total of 65 cases(85 eyes)that diagnosed with age-related cataract and received surgery in Aier Eye Hospital(East of Chengdu)were included in this prospective nonrandomized controlled study. The patients were divided into two groups according to the surgery choice, with 23 cases(30 eyes)in femtosecond laser assisted group, and 42 cases(55 eyes)in traditional phacoemulsification group. OCTA was used to compare the changes in central macular thickness, thickness of nerve fiber layer in optic disc, vessel density and blood perfusion preoperatively, and at 1 d and 1 mo postoperatively.RESULTS: BCVA of patients in the two groups was significantly improved and IOP was significantly reduced at 1 mo postoperatively(all P<0.01). The macular nerve fiber layer thickness of the femtosecond laser-assisted group was increased at 1 d and 1 mo postoperatively(all P<0.05), while there was no statistical difference in the traditional phacoemulsification group before and after surgery(all P>0.05); there were significant differences in nerve fiber layer thickness in optic disc, vessel density and blood perfusion in both macula and optic disc of the traditional phacoemulsification group(all P<0.05), but there were no differences in the femtosecond laser assisted group(all P>0.05). Furthermore, there were no significant differences in foveal avascular zone area in the two groups of patients(all P>0.05).CONCLUSION: Femtosecond laser-assisted cataract surgery had less impact on retinal vessels.

		                        			Objective To analyze the changing trends of the incidence and onset age of cervical cancer in Jiangsu Province by using cancer registration data from 2009 to 2019. Methods The information of national cancer registries with continuous data from 2009 to 2019 was selected, and the quality control indices of cancer registration must be up to standards. A total of 16 registries were included in this study. Statistical analysis indicators include the crude incidence rate of cervical cancer, age-standardized incidence rate, actual average onset age, age-standardized average onset age, and average annual percentage change (AAPC). A birth cohort model was constructed to analyze the incidence of cervical cancer among women born from 2009 to 2019 and its incidence trend. Results From 2009 to 2019, the crude and age-standardized incidence rates of cervical cancer among women in Jiangsu Province showed upward trends, with AAPCs of 5.62% (95%CI: 3.47−7.82) and 4.14% (95%CI: 2.06−6.27), respectively. The incidence rate of cervical cancer in rural areas (AAPC=4.46, 95%CI: 1.13−7.91) increased more than that in urban areas (AAPC=3.83, 95%CI: 2.81−4.86). The actual average onset age of cervical cancer increased from 51.53 years in 2009 to 55.07 years in 2019 (β=0.36, P<0.05). The age-standardized average onset age increased from 48.89 years in 2009 to 50.43 years in 2019 (β=0.21, P<0.05). The age composition ratios of cervical cancer in the age group of 60 years and older were 31.90% in 2019 and 22.40% in 2009 (β=3.66, P<0.05). The incidence of cervical cancer in the same age group of people with different birth years showed an upward trend with the increase in birth year. Conclusion From 2009 to 2019, the incidence rate of cervical cancer in Jiangsu Province showed an upward trend, and this trend was more obvious in rural areas than in urban areas. In addition, the average onset age of cervical cancer showed an upward trend.

		                        			OBJECTIVE To explore the material basis of the anti-inflammatory effect of the petroleum ether extract from Melastoma dodecandrum by establishing its fingerprint and combining it with cellular pharmacodynamics experiments. METHODS HPLC method was adopted; the fingerprints of 20 batches of petroleum ether extract from M. dodecandrum were drawn using The Similarity Evaluation System of TCM Chromatographic Fingerprint (2012 edition); similarity evaluation and common peak identification were carried out. The lipopolysaccharide-induced inflammation model of mice mononuclear macrophages (RAW264.7) was established; the inhibitory rates of nitric oxide (NO) and tumor necrosis factor α (TNF-α) were used as indexes to investigate the anti-inflammatory activity of the petroleum ether extract from M. dodecandrum; grey correlation degree method and partial least square regression analysis were adopted to study the spectrum-effect relationship. Molecular docking was used to validate the binding activity of the anti-inflammatory active ingredients with TNF-α and iNOS protein receptor. RESULTS There were 19 common peaks in the fingerprint of the petroleum ether extract from M. dodecandrum, the similarity of 20 batches of samples ranged from 0.603-0.990, and five components were identified, such as vitexin (peak 5), isovitexin (peak 6), ellagic acid (peak 7), quercetin (peak 9) and luteolin (peak 10). The grey correlation degree between 19 common peaks of the petroleum ether extract from M. dodecandrum and the inhibition rates of NO and TNF-α were all greater than 0.7; peaks 19, 13, 9 (quercetin), 12, 5 (vitexin), 6 (isovitexin), 8, 7 (ellagic acid), 18, 1 were positively correlated with NO inhibition rate, and peaks 8, 10 (luteolin), 13, 15, 3, 19, 17, 7 (ellagic acid), 18, 1 were positively correlated with inhibition rate of TNF-α. The binding energies of vitexin, isovitexin and quercetin with iNOS protein receptor were less than -5.0 kcal/mol. CONCLUSIONS Vitexin, isovitexin and quercetin may be the basis of the anti-inflammatory effect of the petroleum ether extract from M.dodecandrum.
