Intraoperative cell salvage (IOCS) has been widely applied as an important blood conservation measure in surgical operations. However, there is currently a lack of clinical practice guidelines for the implementation of IOCS in patients with malignant tumors. This report aims to provide clinicians with recommendations on the use of IOCS in patients with malignant tumors based on the review and assessment of the existed evidence. Data were derived from databases such as PubMed, Embase, the Cochrane Library and Wanfang. The guideline development team formulated recommendations based on the quality of evidence, balance of benefits and harms, patient preferences, and health economic assessments. This study constructed seven major clinical questions. The main conclusions of this guideline are as follows: 1) Compared with no perioperative allogeneic blood transfusion (NPABT), perioperative allogeneic blood transfusion (PABT) leads to a more unfavorable prognosis in cancer patients (Recommended); 2) Compared with the transfusion of allogeneic blood or no transfusion, IOCS does not lead to a more unfavorable prognosis in cancer patients (Recommended); 3) The implementation of IOCS in cancer patients is economically feasible (Recommended); 4) Leukocyte depletion filters (LDF) should be used when implementing IOCS in cancer patients (Strongly Recommended); 5) Irradiation treatment of autologous blood to be reinfused can be used when implementing IOCS in cancer patients (Recommended); 6) A careful assessment of the condition of cancer patients (meeting indications and excluding contraindications) should be conducted before implementing IOCS (Strongly Recommended); 7) Informed consent from cancer patients should be obtained when implementing IOCS, with a thorough pre-assessment of the patient's condition and the likelihood of blood loss, adherence to standardized internally audited management procedures, meeting corresponding conditions, and obtaining corresponding qualifications (Recommended). In brief, current evidence indicates that IOCS can be implemented for some malignant tumor patients who need allogeneic blood transfusion after physician full evaluation, and LDF or irradiation should be used during the implementation process.

Objective·To investigate the effect of early postoperative administration of zoledronic acid on fracture healing and functional recovery in elderly patients with osteoporotic femoral intertrochanteric fracture treated with proximal femoral nail antirotation(PFNA)surgery,and explore other potential prognostic factors.Methods·A total of 174 patients with femoral intertrochanteric fractures of 80 years old or above who underwent PFNA treatment in Ruijin Hospital,Shanghai Jiao Tong University School of Medicine from January,2016 to February,2022,were divided into experimental group(n=26)and control group(n=148)according to whether they received zoledronic acid early after surgery.All patients were followed up twice at 6 weeks and 12 weeks after surgery.The patients in the experimental group were matched with the control group by propensity score matching(PSM)at a ratio of 1:3(the matching factors included age,gender,fracture type,and body mass index).General characteristics,as well as fracture healing and functional recovery at the two follow-up visits were compared between the two groups after matching.Subsequently,Logistic regression was used to explore the potential prognostic factors on fracture healing at 12 weeks after surgery.Results·PSM resulted in 25 patients in the experimental group and 65 patients in the control group,and there were no statistically significant differences in baseline characteristics between the two groups.The fracture healing rates at 6 weeks and 12 weeks after surgery in the experimental group(16.0%and 96.0%,respectively)were higher than those in the control group(1.5%and 73.8%),and the differences were statistically significant(P<0.05).Harris hip function score in the experimental group at 12 weeks was significantly higher than that of the control group(P=0.019).The results of Logistic regression analysis showed that good surgical reduction(OR=12.52,95%CI 2.67?58.74,P=0.001),early postoperative administration of zoledronic acid(OR=10.14,95%CI 1.01?102.09,P=0.049),and higher serum albumin level(OR=1.15,95%CI 1.02?1.29,P=0.025)were the favorable factors of early fracture healing,while unstable fracture(OR=0.10,95%CI 0.03?0.31,P=0.000)was the unfavorable factor.Conclusion·For elderly patients with osteoporotic intertrochanteric femoral fractures treated with PFNA surgery,early postoperative administration of zoledronic acid can promote fracture healing and lead to better functional recovery;in addition,good surgical reduction and higher serum albumin levels are favorable factors for fracture healing,whereas unstable fracture presents as a hindrance to the healing process.

Background/Aims: Chronic hepatitis C (CHC) patients who failed antiviral therapy are at increased risk for hepatocellular carcinoma (HCC). This study assessed the potential role of metformin and statins, medications for diabetes mellitus (DM) and hyperlipidemia (HLP), in reducing HCC risk among these patients. Methods: We included CHC patients from the T-COACH study who failed antiviral therapy. We tracked the onset of HCC 1.5 years post-therapy by linking to Taiwan’s cancer registry data from 2003 to 2019. We accounted for death and liver transplantation as competing risks and employed Gray’s cumulative incidence and Cox subdistribution hazards models to analyze HCC development. Results: Out of 2,779 patients, 480 (17.3%) developed HCC post-therapy. DM patients not using metformin had a 51% increased risk of HCC compared to non-DM patients, while HLP patients on statins had a 50% reduced risk compared to those without HLP. The 5-year HCC incidence was significantly higher for metformin non-users (16.5%) versus non-DM patients (11.3%; adjusted sub-distribution hazard ratio [aSHR]=1.51; P=0.007) and metformin users (3.1%; aSHR=1.59; P=0.022). Statin use in HLP patients correlated with a lower HCC risk (3.8%) compared to non-HLP patients (12.5%; aSHR=0.50; P<0.001). Notably, the increased HCC risk associated with non-use of metformin was primarily seen in non-cirrhotic patients, whereas statins decreased HCC risk in both cirrhotic and non-cirrhotic patients. Conclusions Metformin and statins may have a chemopreventive effect against HCC in CHC patients who failed antiviral therapy. These results support the need for personalized preventive strategies in managing HCC risk.

Objective To evaluate the effects of fasting and high-fat diet on the pharmacokinetics of moxifloxacin in Chinese healthy adult subjects.Methods A single-center,randomized,open,single-dose trial design was used in this study,healthy subjects were assigned to receive single dose of moxifloxacin tablets 0.4 g in either fasting or high-fat diet state,and blood samples were taken at different time points,respectively.The concentrations of moxifloxacin in plasma were determined by liquid chromatography-tandem mass spectrometry.Results The main pharmacokinetic parameters of moxifloxacin in fasting state and high-fat diet states were as follows:Cmax were(2 286.09±802.64)and(1 963.33±474.99)ng·mL-1;t1/2 were(12.32±1.42)and(13.56±1.38)h;AUC0-twere(2.70±0.51)×104 and(2.60±0.55)×104 ng·mL-1·h;AUC0-∞ were(2.88±0.54)×104 and(2.85±0.63)×104 ng·mL-1·h;tmax were 1.50 and 2.00 h.After high-fat diet,the AUC was not significantly changed,Cmax was decreased by 14.12％,and tmax was indistinctively delayed(all P＞0.05).Conclusion Food had no effects on the absorption rate and degree of moxifloxacin.

Objective: To investigate the role and related mechanism of ubiquitin-like protein FAT10 in the angiotensin Ⅱ (AngⅡ)-induced endothelial cell inflammatory responses. Methods: The Western blot was used to detect the protein expression of FAT10 in 16-weeks old WKY rat carotid artery, thoracic aorta artery, renal artery and vascular smooth muscle cells (VSMC), human umbilical vein endothelial cells (HUVEC) and human breast cancer cells (MDA-MB-231). The optimal concentration and stimulation time of AngⅡ on inducing the highest FAT10 in HUVEC were determined. The following plasmids were constructed: control plasmid, overexpression FAT10 plasmid (Flag-FAT10), invalid interference plasmid, and interference FAT10 plasmid (sh-FAT10). These plasmids were then transfected into HUVEC cells and divided into following groups: control group, Flag-FAT10 group, invalid interference group, and sh-FAT10 group. After culturing with 100 nmol/L AngⅡ for 36 h, the control group and the Flag-FAT10 group were treated with reactive oxygen species scavenger N-acetyl-L-cysteine ​​(NAC), the protein expression levels of the inflammatory factor monocyte chemotactic protein-1 (MCP-1) and tumor necrosis factor-α (TNF-α) were measured. Laser confocal microscopy was used to detect the generation levels of reactive oxygen species in the cells of vrious groups. Results: FAT10 was expressed in carotid artery, thoracic aorta, and renal artery of normal blood pressure rats and expressed in HUVEC, VSMC, MDA-MB-231. The expression level of FAT10 gradually increased in proportion to the increase of the time and concentration of AngⅡ stimulation in HUVEC, and the expression level of FAT10 was the highest when the HUVEC was treated with 100 nmol/L AngⅡ for 36 h (P<0.01). The protein expression level of MCP-1 (P<0.001) and TNF-α (P<0.01) was higher in AngⅡ treated HUVEC with FAT10 overexpression, while the expression level of MCP-1 and TNF-α protein was lower in AngⅡ treated HUVEC with FAT10 knockdown (all P<0.01). The level of intracellular reactive oxygen species (ROS) production was significantly increased with FAT10 overexpression (P<0.001), and the level of ROS was decreased when the expression of FAT10 was interfered (P<0.05). The increased level of MCP-1 and TNF-α proteins in FAT10 overexpressed HUVEC was reversed by NAC (all P<0.05). Conclusion: FAT10 promotes the release of inflammatory factors induced by AngⅡ in endothelial cells by increasing the level of intracellular ROS production.

Objective:To investigate the efficacy of hemodiafiltration combined with hemoperfusion in the treatment of secondary hyperparathyroidism (SHPT) in patients undergoing maintenance hemodialysis (MHD).Methods:A total of 40 patients with SHPT undergoing MHD who received treatment at the Blood Purification Center of The First Affiliated Hospital of Anhui University of Science and Technology from February 2021 to March 2023 were included in this prospective cohort study. They were randomly divided into a control group and an observation group ( n = 20/group).The control group received a single high flux hemodialysis, while the observation group used a combination of hemodialysis filtration and hemoperfusion for 3 months. In both groups, the changes in hemoglobin, blood urea nitrogen, serum creatinine, serum calcium, serum phosphorus,and parathyroid hormone levels were compared before and after dialysis. Results:After dialysis, the hemoglobin level in the observation group was (119.45 ± 5.27) g/L, which was significantly higher than (106.30 ± 6.52) g/L in the control group ( t = -7.02, P < 0.001). The serum phosphorus level in the observation group was (1.18 ± 0.17) mmol/L, which was significantly lower than (1.52 ± 0.22) mmol/L in the control group ( t = 5.49, P < 0.001). The parathyroid hormone level in the observation group was (122.14 ± 40.57) ng/L, which was significantly lower than (168.78 ± 78.27) ng/L in the control group ( t = 2.39, P = 0.023). Conclusion:Hemodiafiltration combined with hemoperfusion can reduce clinical symptoms, increase hemoglobin level, and reduce phosphorus and parathyroid hormone levels in patients with SHPT undergoing MHD, which deserves clinical promotion.

Cerebral hypoxia often brings irreversible damage to the central nervous system, which seriously endangers human health. It is of great significance to further explore the mechanism of hypoxia-associated brain injury. As a programmed cell death, ferroptosis mainly manifests as cell death caused by excessive accumulation of iron-dependent lipid peroxides. It is associated with abnormal glutathione metabolism, lipid peroxidation and iron metabolism, and is involved in the occurrence and development of various diseases. Studies have found that ferroptosis plays an important role in hypoxia-associated brain injury. This review summarizes the mechanism of ferroptosis, and describes its research progress in cerebral ischemia reperfusion injury, neonatal hypoxic-ischemic brain damage, obstructive sleep apnea-induced brain injury and high-altitude hypoxic brain injury.
