Objective:This study aimed to validated the diagnostic accuracy of Global Leadership Initiative on Malnutrition(GLIM)criteria for malnutrition in pancreatic cancer patients undergoing pancreaticoduodenectomy and to evaluated its prognostic value for postoperative outcome.Methods:A retrospective analysis was conducted on 230 consecutive pancreatic cancer patients who underwent pancreaticoduodenectomy at the Department of Pancreatobiliary Surgery,Sun Yat-sen University Cancer Center,between January 2018 to January 2024.Patients were stratified into malnutrition group and non-malnutrition group using Nutritional Risk Screening 2002(NRS 2002)and GLIM criteria.Multivariable logistic regression identified independent risk factors for postoperative morbidity.Results:GLIM criteria identified malnutrition in 96 patients(41.7％).Compared with the non-malnourished group,the number of preoperative nutritional support(t=20.038,P<0.001),the number of preoperative enteral nutrition support(t=8.377,P=0.004),the number of preoperative parenteral nutrition support(t=22.302,P<0.001),the number of anemia(t=8.037,P=0.005)and preoperative parenteral nutrition use days(t=-2.898,P=0.009),the difference was statistically significant.There were statistically significant differences in C-reactive protein(t=10.944,P=0.008),NLR(t=-2.523,P=0.012)and PNI(t=-2.397,P=0.017)between the two groups before surgery.Preoperative BMI(t=-4.410,P<0.001)was significantly lower in the malnourished group.The number of postoperative parenteral nutrition days(Z=-2.283,P=0.022)and amino acid supplementation during postoperative hospitalization were significantly higher in the malnourished group(Z=-2.309,P=0.021).The incidence of malnutrition was higher in patients with Clavien-Dindo grade≥Ⅲ(P=0.030)and intra-abdominal infections(P=0.049).Multivariable analysis identified preoperative weight loss(OR=2.154,95％CI:1.158～4.005;P=0.015)and BMI reduction(OR=0.175,95％CI:0.040～0.775;P=0.022)as independent predictors of postoperative complications.Conclusions:The GLIM standard effectively characterize malnutrition status in pancreatic cancer patients after pancreaticoduodenectomy patients and demonstrate superior predictive performance for postoperative morbidity.It has good predictive performance and clinical application value.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective: Compare and analyze the results of the domestic Lanyi AH600 glycated hemoglobin analyzer and other different detection systems to understand the comparability of the detection results of different detectors, and establish the best cut point of Lanyi AH600 determination of haemoglobin A1c (HbA1c) in the diagnosis of diabetes. Methods: Multi center cohort study was adopted. The clinical laboratory departments of 18 medical institutions independently collected test samples from their respective hospitals from March to April 2022, and independently completed comparative analysis of the evaluated instrument (Lanyi AH600) and the reference instrument HbA1c. The reference instruments include four different brands of glycosylated hemoglobin meters, including Arkray, Bio-Rad, DOSOH, and Huizhong. Scatter plot was used to calculate the correlation between the results of different detection systems, and the regression equation was calculated. The consistency analysis between the results of different detection systems was evaluated by Bland Altman method. Consistency judgment principles: (1) When the 95% limits of agreement (95% LoA) of the measurement difference was within 0.4% HbA1c and the measurement score was≥80 points, the comparison consistency was good; (2) When the measurement difference of 95% LoA exceeded 0.4% HbA1c, and the measurement score was≥80 points, the comparison consistency was relatively good; (3) The measurement score was less than 80 points, the comparison consistency was poor. The difference between the results of different detection systems was tested by paired sample T test or Wilcoxon paired sign rank sum test; The best cut-off point of diabetes was analyzed by receiver operating characteristic curve (ROC). Results: The correlation coefficient R² of results between Lanyi AH600 and the reference instrument in 16 hospitals is≥0.99; The Bland Altman consistency analysis showed that the difference of 95% LoA in Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180) was -0.486%-0.325%, and the measurement score was 94.6 points (473/500); The difference of 95% LoA in the Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant II) was -0.727%-0.612%, and the measurement score was 89.8 points; The difference of 95% LoA in the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT) was -0.231%-0.461%, and the measurement score was 96.6 points; The difference of 95% LoA in the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT) was -0.469%-0.479%, and the measurement score was 91.9 points. The other 14 hospitals, Lanyi AH600, were compared with 4 reference instrument brands, the difference of 95% LoA was less than 0.4% HbA1c, and the scores were all greater than 95 points. The results of paired sample T test or Wilcoxon paired sign rank sum test showed that there was no statistically significant difference between Lanyi AH600 and the reference instrument Arkray HA8180 (Z=1.665,P=0.096), with no statistical difference. The mean difference between the measured values of the two instruments was 0.004%. The comparison data of Lanyi AH600 and the reference instrument of all other institutions had significant differences (all P<0.001), however, it was necessary to consider whether it was within the clinical acceptable range in combination with the results of the Bland-Altman consistency analysis. The ROC curve of HbA1c detected by Lanyi AH600 in 985 patients with diabetes and 3 423 patients with non-diabetes was analyzed, the area under curve (AUC) was 0.877, the standard error was 0.007, and the 95% confidence interval 95%CI was (0.864, 0.891), which was statistically significant (P<0.001). The maximum value of Youden index was 0.634, and the corresponding HbA1c cut point was 6.235%. The sensitivity and specificity of diabetes diagnosis were 76.2% and 87.2%, respectively. Conclusion: Among the hospitals and instruments currently included in this study, among these four hospitals included Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180), Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant Ⅱ), the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT), and the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT), the comparison between Lanyi AH600 and the reference instruments showed relatively good consistency, while the other 14 hospitals involved four different brands of reference instruments: Arkray, Bio-Rad, DOSOH, and Huizhong, Lanyi AH600 had good consistency with its comparison. The best cut point of the domestic Lanyi AH600 for detecting HbA1c in the diagnosis of diabetes is 6.235%.

Purpose: The aim of this study was to compare the efficacy of liver transplantation (LT) and liver resection (LR) for hepatocellular carcinoma (HCC) patients with portal vein tumor thrombus (PVTT) and to investigate risk factors affecting prognosis. Materials and Methods: A total of 94 HCC patients with PVTT type I (segmental PVTT) and PVTT type II (lobar PVTT) were involved and divided into LR (n=47) and LT groups (n=47). Recurrence-free survival (RFS) and overall survival (OS) were compared before and after inverse probability of treatment weighting (IPTW). Prognostic factors for RFS and OS were explored. Results: Two treatment groups were well-balanced using IPTW. In the entire cohort, LT provided a better prognosis than LR. Among patients with PVTT type I, RFS was better with LT (p=0.039); OS was not different significantly between LT and LR (p=0.093). In subgroup analysis of PVTT type I patients with α-fetoprotein (AFP) levels >200 ng/mL, LT elicited significantly longer median RFS (18.0 months vs. 2.1 months, p=0.022) and relatively longer median OS time (23.6 months vs. 9.8 months, p=0.065). Among patients with PVTT type II, no significant differences in RFS and OS were found between LT and LR (p=0.115 and 0.335, respectively). Multivariate analyses showed treatment allocation (LR), tumor size (>5 cm), AFP and aspartate aminotransferase (AST) levels to be risk factors of RFS and treatment allocation (LR), AFP and AST as risk factors for OS. Conclusion LT appeared to afford a better prognosis for HCC with PVTT type I than LR, especially in patients with AFP levels >200 ng/mL.

The current study was designed to explore the brain protection mechanism of Xinglou Chengqi Decoction (XCD) based on gut microbiota analysis and network pharmacology. A transient middle cerebral artery occlusion (MCAO) model of mice was established, followed by behavioral evaluation, TTC and TUNEL staining. Additionally, to investigate the effects of gut microbiota on neurological function after stroke, C57BL/6 mice were treated with anti-biotic cocktails 14 days prior to ischemic stroke (IS) to deplete the gut microbiota. High-throughput 16S rDNA gene sequencing, metabonomics technique, and flow multifactor technology were used to analyze bacterial communities, SCFAs and inflammatory cytokines respectively. Finally, as a supplement, network pharmacology and molecular docking were applied to fully explore the multicomponent-multitarget-multichannel mechanism of XCD in treating IS, implicated in ADME screening, target identification, network analysis, functional annotation, and pathway enrichment analysis. We found that XCD effectively improved neurological function, relieved cerebral infarction and decreased the neuronal apoptosis. Moreover, XCD promoted the release of anti-inflammatory factor like IL-10, while down-regulating pro-inflammatory factors such as TNF-α, IL-17A, and IL-22. Furthermore, XCD significantly increased the levels of short chain fatty acids (SCFAs), especially butyric acid. The mechanism might be related to the regulation of SCFAs-producing bacteria like Verrucomicrobia and Akkermansia, and bacteria that regulate inflammation like Paraprevotella, Roseburia, Streptophyta and Enterococcu. Finally, in the network pharmacological analysis, 51 active compounds in XCD and 44 intersection targets of IS and XCD were selected. As a validation, components in XCD docked well with key targets. It was obviously that biological processes were mainly involved in the regulation of apoptotic process, inflammatory response, response to fatty acid, and regulation of establishment of endothelial barrier in GO enrichment. XCD can improve neurological function in experimental stroke mice, partly due to the regulation of gut microbiota. Besises, XCD has the characteristic of "multi-component, multi-target and multi-channel" in the treatment of IS revealed by network pharmacology and molecular docking.

Background: Few data are available regarding the progression of liver disease and therapeutic efficacy in chronic hepatitis B virus (HBV) carriers infected by mother-to-child transmission (MTCT). This study aimed to investigate these two aspects by comparing the adult chronic HBV carriers in MTCT group with those in horizontal transmission group. Methods: The 683 adult chronic HBV patients qualified for liver biopsy including 191 with MTCT and 492 with horizontal transmission entered the multi-center prospective study from October 2013 to May 2016. Biopsy results from 217 patients at baseline and 78 weeks post antiviral therapy were collected. Results: Patients infected by MTCT were more likely to have e antigen positive (68.6% vs. 58.2%, χ² = -2.491, P = 0.012) than those with horizontal transmission. However, in patients with MTCT, levels of alkaline phosphatase (ALP) (P = 0.031), Fibroscan (P = 0.013), N-terminal propeptide of Type III procollagen (PIIINP) (P = 0.014), and Laminin (LN) (P = 0.006) were high, in contrast to the patients with horizontal transmission for whom the levels of albumin (ALB) (P = 0.041), matrix metalloproteinase-3 (MMP-3) (P = 0.001) were high. The 47.2% of patients with MTCT and 36.8% of those with horizontal transmission had significant liver fibrosis (P = 0.013). Following antiviral therapy for 78 weeks, 21.2% and 38.0% patients with MTCT and horizontal transmission acquired hepatitis B e antigen (HBeAg) clearance, respectively (P = 0.043), and the virological response rates were 54.7% and 74.1% in the MTCT and horizontal groups, respectively (P = 0.005). MTCT was a risk factor for HBeAg clearance and virological response. Conclusion: Adult patients with MTCT were more prone to severe liver diseases, and the therapeutic efficacy was relatively poor, which underlined the importance of earlier, long-term treatment and interrupting perinatal transmission.

OBJECTIVETo explore the anesthetic effect and safety of ultrasound-guided thoracic paravertebral blockade in video-assisted thoracoscopic sympathectomy for treatment of palmar hyperhidrosis.

METHODSA total of 120 patients undergoing video-assisted thoracoscopic sympathectomy for moderate or severe hyperhidrosis were randomized to receive ultrasound-guided thoracic paravertebral blockade (group A, n=60) or general anesthesia with tracheal intubation (group B, n=60). In both groups routine monitoring and radial artery catheterization were used. The patients in group A were given oxygen inhalation via a nasal tube after thoracic paravertebral blockade, and those in group B had intratracheal intubation. Blood gas analyses were conducted 5 min before and 5 min after the operation and the clinical outcomes and complications were recorded in each group.

RESULTSAll the patients completed the operations safely and none of the patients with thoracic paravertebral blockade required conversion to general anesthesia. Significant differences were recorded between groups A and B in anesthetic preparation time (6.26∓2.09 vs 46.32∓15.76 min), awakening time (6.26∓2.09 vs 46.32∓15.76 min), and mean hospitalization expense (6355.54∓426.00 vs 8932.25∓725.98 RMB Yuan). Compared with those in group B, the patients in group A showed a significantly lower rate of postoperative throat discomfort (0% vs 100%), a shorter monitoring time (2 h vs 12 h), and faster recovery time for food intake (2 h vs 6 h). The parameters of artery blood gas analysis both before and after the operation were similar between the two groups, but the postoperative variations differed significantly between the two groups in pH value and PaCObut not in PaO.

CONCLUSIONUltrasound-guided thoracic paravertebral blockade is safe and effective in video-assisted thoracoscopic sympathectomy for palmar hyperhidrosis and is associated with less complications and better postoperative recovery.

OBJECTIVETo establish a gastric cancer cell line with stable expression of metastasis-associated in colon cancer 1 (MACC1) and detect the changes in tumor-related gene expression profiles for investigating the possible regulation mechanisms between MACC1 and the differentially expressed genes.

METHODSThe full-length MACC1 cDNA was amplified from human embryonic kidney 293FT cells and cloned into the pBaBb-puro vector. The recombinant pBaBb-puro-MACC1 expression vector, after identification with restriction enzyme digestion, was transfected into 293FT cells, and the expression of fluorescent reporter gene was observed. pBaBb-puro-MACC1 vector was transfected into human gastric cancer BGC-823 cell line to establish BGC-823/pBaBb-puro-MACC1 cell line stably expressing MACC1. Quantitative RT-PCR and Western blotting were used to detect MACC1 expression in both BGC-823/pBaBb-puro-MACC1 and control BGC-823 cells. High-throughout cDNA microarray was used to screen the effects of MACC1 on the gene expression profiles of gastric cancer cells.

RESULTSThe recombinant pBaBb-puro-MACC1 plasmid was successfully constructed and verified by PCR and sequencing. BGC-823/pBaBb-puro-MACC1 cells showed significantly increased MACC1 mRNA expression as compared with the control cells. The results of cDNA microarray identified 33 up-regulated and 24 down-regulated genes in the cells after MACC1 transfection involved were in various cellular functions.

CONCLUSIONThe established BGC-823/pBaBb-puro-MACC1 gastric cancer cell line show some important molecular changes caused by MACC1.
