Lipidomics is an emerging discipline that systematically studies the various types,functions,and metabolic pathways of lipids within living organisms.This field compares changes in diseases or drug impact,identifying biomarkers and molecular mechanisms present in lipid metabolic networks across different physiological or pathological states.Through employing analytical chemistry within the realm of lipidomics,researchers analyze traditional Chinese medicine(TCM).This analysis aids in uncovering potential mechanisms for treating diverse physiopathological conditions,assessing drug efficacy,un-derstanding mechanisms of action and toxicity,and generating innovative ideas for disease prevention and treatment.This manuscript assesses recent literature,summarizing existing lipidomics technologies and their applications in TCM research.It delineates the efficacy,mechanisms,and toxicity research related to lipidomics in Chinese medicine.Additionally,it explores the utilization of lipidomics in quality control research for Chinese medicine,aiming to expand the application of lipidomics within this field.Ultimately,this initiative seeks to foster the integration of traditional medicine theory with modern science and technology,promoting an organic fusion between the two domains.

Pancreatic cancer is highly malignant and difficult to treat. The implantation of radioactive seed has opened up a new treatment option for pancreatic cancer. Although the implantation of radioactive seed in the treatment of pancreatic cancer has achieved good results, due to the special anatomical location of pancreatic cancer and the dense distribution of important tissues and organs around the tumor, the operation of seed implantation for pancreatic cancer has become a clinical treatment challenge. We applied the method of 3D printing template navigation and constraining the direction of the puncture needle. The puncture needle followed the safe puncture path designed in the preoperative treatment planning system, effectively avoiding important tissues and organs, and implanted radioactive seeds in the tumor. The operation of seed implantation was simplified, homogenized and made safe. In this group of cases, the proportion of successful particle implantation using 3D printing template navigation was 89.5%. All cases met the preoperative treatment plan in postoperative dose verification and achieved the purpose of radioactive seed implantation treatment.

Objective To investigate the effect of tirofiban combined with oxiracetam on acute anterior circulation progressive cerebral infarction.Methods A total of 171 patients with acute anteri-or circulation progressive cerebral infarction from October 2022 to January 2024 were enrolled and ran-domly divided into three groups using a random number table.The control group of 57 patients re-ceived conventional treatment,the observation group A received tirofiban in addition to conventional treatment,and the observation group B received oxiracetam on the basis of observation group A's treat-ment.The effectiveness indicators[including the rates of neurological improvement and neurological deterioration at 14 days after treatment,the rate of good prognosis and modified Rankin Scale(MRS)scores at 90 days after treatment,as well as the National Institutes of Health Stroke Scale(NIHSS)scores at 7 and 14 days after treatment and their differences from baseline],cognitive function[as-sessed using the Montreal Cognitive Assessment(MOCA)],and safety indicators(incidence rates of symptomatic intracranial hemorrhage,fatal intracranial hemorrhage,and mortality at 90 days after treat-ment)were compared among the three groups.Results There were no statistically significant differ-ences in the rates of neurological improvement and neurological deterioration at 14 days after treatment,the rate of good prognosis,and MRS scores at 90 days after treatment among the three groups(P＞0.05).There were statistically significant differences in NIHSS scores between baseline and 7 and 14 days after treatment in all three groups(P＜0.05),and the differences in NIHSS scores from baseline at the above time points were higher in observation group B than in observation group A and the control group(P＜0.05).There were no statistically significant differences in MOCA scores among the three groups before treatment(P＞0.05);however,the MOCA scores in the observation group B were higher than those in observation group A and the control group at 14,30,and 90 days after treatment(P＜0.05).There were no statistically significant differences in the incidence rates of symptomatic intracranial hemorrhage,fatal intracranial hemorrhage,and mortality at 90 days after treatment among the three groups(P＞0.05).Conclusion Tirofiban combined with oxiracetam can improve cognitive function in patients with acute anterior circulation progressive cerebral infarc-tion without increasing the risk of hemorrhage,and has better prognosis.

Objective:To explore the effect and mechanism of Chlorfortunone A(ChlA) in the treatment of diabetic nephropathy(DN) in mice.Methods:The DN model mice were assigned to DN, low-dose ChlA(ChlAL) and high-dose ChlA(ChlAH), and the normal control groups(Ctrl). Kidney tissue was analyzed via HE and Masson staining, and urine albumin, fasting blood glucose and kidney weight were measured. Collagen1 and α-SMA proteins were detected in renal tissues. The level of GSH-px, SOD, CAT, and TGF-β were detected. The TGF-β/Smad2 pathway in kidney tissue was detected. The mechanism was verified by setting the high glucose+ ChlA+ TGF-β group in MPC-5 cells. The proliferation of the cells and DCFDA staining were detected.Results:Compared to the Ctrl group, the DN group had significantly higher UACR and kidney weight( P<0.001). High-dose ChlA reduced UACR and kidney weight( P<0.05), with no effect on blood glucose( P>0.05). Masson staining showed reduced fibrosis with ChlA treatment. Collagen I and α-SMA expressions were significantly higher in DN( P<0.001) and decreased with ChlA treatment( P<0.05). GSH-px, SOD, and CAT levels were lower in DN( P<0.001), while TGF-β was elevated( P<0.001); ChlA increased antioxidant enzymes and decreased TGF-β( P<0.05). The TGF-β/Smad2 pathway was upregulated in DN( P<0.001) and inhibited by ChlA( P<0.001). In vitro, ChlA reduced cell proliferation( P<0.05) and increased ROS levels( P<0.001). Conclusions:ChlA alleviates kidney injury and fibrosis in DN mice, reduces oxidative stress, which may be related to the inhibition of the TGF-β/Smad2 pathway.

In recent years,with the increasing proportion of pulmonary nodules,preoperative percutaneous lung puncture biopsy and bronchoscopic biopsy have received more and more attention.A large amount of clinical evidences indicate that lung puncture biopsy of stageⅠnon-small cell lung cancer(NSCLC)is safe and feasible.However,due to the histological characteristics of pulmonary ground-glass nodule(GGN),puncture biopsy of GGNs is more likely to cause bleeding and cough,and the tumor cells may be implanted along the alveolar wall or needle tract under the impact of blood flow or airflow,leading to the pleural recurrence and tumor spread through air spaces(STAS),when compared with puncture biopsy of solid nodules.Therefore,percutaneous lung puncture biopsy should be carefully adopted,especially for the patients who have subpleural nodules with visceral pleura invasion and lymphocyte infiltration.(J Intervent Radiol,2024,32:7-11)

Objective To analyze the clinical outcomes of extended thymectomy for myasthenia gravis (MG) patients under different surgical approaches, and to determine the factors affecting the prognosis of MG. Methods The MG patients who underwent extended thymectomy from January 2014 to March 2021 in our hospital were retrospectively collected. According to the surgical approach, they were divided into a subxiphoid group and an intercostal group, and the perioperative results and prognosis were compared between the two groups. A “good outcome” was defined as complete stable remission (CSR), pharmacological remission (PR) or minimal manifestations state (MMS); a “poor outcome” was defined as outcomes worse than MMS. Univariate and multivariate logistic regression analyses were performed to assess the factors associated with the good outcomes. Results A total of 187 MG patients were included in the study, including 82 males and 105 females, with a median age of 50 (36, 60) years. There were 134 patients in the intercostal group and 53 patients in the subxiphoid group. Compared with the intercostal group, although the operation time of the subxiphoid group was longer [200.0 (172.0, 232.0) min vs. 141.0 (118.0, 169.0) min, P<0.001], the intraoperative blood loss was less [10.0 (10.0, 20.0) mL vs. 20.0 (10.0, 50.0) mL, P<0.001], the postoperative hospital stay was shorter [3.0 (2.5, 4.0) d vs. 5.0 (3.0, 7.0) d, P<0.001], and the incidence of complications was lower [1 (1.9%) vs. 26 (19.4%), P=0.001]. A total of 159 (85.0%) patients were followed up for a median period of 46 (13, 99) months, with a good outcome rate of 90.6% and CSR rate of 33.3%. There were no statistical differences in PR, MMS or overall good outcome rates between the two groups (P>0.05). Multivariate logistic analysis showed that age≤50 years was an independent predictor for "good outcome" of MG patients. Conclusion Extended thymectomy via subxiphoid for MG is a safe, feasible and effective surgical approach.
