Background: s/Aims: Distal pancreatectomy with splenectomy (DPS) is a common surgical procedure for pancreatic body cancer.However, spleen-preserving distal pancreatectomy (SPDP) utilizing the Warshaw technique (WT) in malignancies is generally not favored due to concerns about inadequate resection. This study aims to assess the feasibility and oncologic outcomes of employing SPDP with WT in pancreatic body cancer. Methods: We conducted a retrospective analysis comparing 21 SPDP patients with 63 DPS patients matched by propensity score from January 2018 to November 2022. Clinical outcomes and follow-up data were analyzed using R. Results: Both groups exhibited similar demographic, intraoperative, and pathological characteristics, with the exception of a reduced number of total lymph nodes (p = 0.006) in the SPDP group. There were no significant differences in the rates of postoperative complications, recurrence, or metastasis. Local recurrence predominantly occurred in the central region as opposed to the spleen region.There were no cases of isolated recurrences in the splenic region. Median overall survival and recurrence-free survival times were 51.5 months for SPDP vs 30.5 months for DPS and 18.7 months vs 16.8 months, respectively (p > 0.05). The incidence of partial splenic infarction and left-side portal hypertension in the SPDP group was 28.6% (6/21) and 9.5% (2/21), respectively, without necessitating splenic abscess puncture, splenectomy, or causing bleeding from perigastric varices. Conclusions SPDP did not negatively impact local recurrence or survival rates in selected pancreatic body cancer patients. Further studies are necessary for validation.

Objective: To analyze the trend in burden of rheumatoid arthritis (RA) in China from 1990 to 2021, so as to provide insights into reducing the RA burden in China. Methods: Data of Global Burden of Disease Study 2021 were collected, and the incidence, mortality and disability-adjusted life years (DALY) of RA in China from 1990 to 2021 were analyzed and compared with global and different Socio-demographic Index (SDI) regions. The trend in burden of RA was analyzed using average annual percent change (AAPC). Results: The crude incidence rates of RA in China increased from 10.87/105 in 1990 to 17.38/105 in 2021, the crude mortality rates increased from 0.41/105 to 0.72/105, and the crude DALY rates increased from 34.26/105 to 58.61/105, with the increases of 59.98%, 77.95% and 71.06%, respectively. From 1990 to 2021, the standardized incidence rates of RA in China showed an increasing trend (AAPC=0.545%, P<0.05), the standardized mortality rates showed a decreasing trend (AAPC=-0.783%, P<0.05), and the standardized DALY rates showed no significant trend (AAPC=-0.017%, P>0.05). In 2021, the standardized incidence rate, standardized mortality rate and standardized DALY rate of RA were higher in females than in males; from 1990 to 2021, the standardized DALY rates of RA showed a decreasing trend in females (AAPC=-0.200%, P<0.05) and an increasing trend in males (AAPC=0.316%, P<0.05). The crude incidence rates of RA first increased and then decreased with age in 2021, reaching the highest in the age group of 75-<80 years at 34.36/105. Both the crude mortality rates and the crude DALY rates increased with age, reaching the highest in the age group of 95 years and older at 26.72/105 and 285.67/105, respectively. The standardized incidence rates and standardized DALY rates of RA in China in 2021 were lower than those in high SDI regions, while the standardized mortality rate was lower than that in medium-low SDI regions. Conclusions The burden of RA in China from 1990 to 2021 showed an upward trend, and was at a high level compared to different SDI regions. Higher disease burden of RA was seen in females and the elderly.

For the past 30 years,percutaneous balloon mitral valve dilatation has been performed under the guidance of X-rays and bedside ultrasound.However,there are still some cases of mitral valve stenosis in the large atrium where balloon dilation failed.Intraperitoneal ultrasound-guided percutaneous balloon mitral valve plasty is accurate and feasible,which can reduce the occurrence of complications and improve the success rate of such elderly complex cases.Two patients with severe mitral stenosis underwent percutaneous balloon mitral valve plasty guided by intracardiac ultrasound.The operations were successful without any complications,which can provide reference for clinical treatment of mitral stenosis.

Objective To monitor the antifungal resistance of clinical isolates of Candida spp.in the East China region.Methods MALDI-TOF MS or molecular methods were used to re-identify the strains collected from January 2018 to December 2022.Antifungal susceptibility testing was performed using the broth microdilution method.The susceptibility test results were interpreted according to the breakpoints of 2022 Clinical and Laboratory Standards Institute(CLSI)documents M27 M44s-Ed3 and M57s-Ed4.Results A total of 3 026 strains of Candida were collected,65.33％of which were isolated from sterile body sites,mainly from blood(38.86％)and pleural effusion/ascites(10.21％).The predominant species of Candida were Candida albicans(44.51％),followed by Candida parapsilosis complex(19.46％),Candida tropicalis(13.98％),Candida glabrata(10.34％),and other Candida species(0.79％).Candida albicans showed overall high susceptibility rates to the 10 antifungal drugs tested(the lowest rate being 93.62％).Only 2.97％of the strains showed dose-dependent susceptibility(SDD)to fluconazole.Candida parapsilosis complex had a SDD rate of 2.61％and a resistance rate of 9.42％to fluconazole,and susceptibility rates above 90％to other drugs.Candida glabrata had a SDD rate of 92.01％and a resistance rate of 7.99％to fluconazole,resistance rates of 32.27％and 48.24％to posaconazole and voriconazole non-wild-type strains(NWT),respectively,and susceptibility rates above 90％to other drugs.Candida tropicalis had resistance rates of 29.55％and 26.24％to fluconazole and voriconazole,respectively,resistance rates of 76.60％and 21.99％to posaconazole and echinocandins non-wild-type strains(NWT),and a resistance rate of 2.36％to echinocandins.Conclusions The prevalence and species distribution of Candida spp.in the East China region are consistent with previous domestic and international reports.Candida glabrata exhibits certain degree of resistance to fluconazole,while Candida tropicalis demonstrates higher resistance to triazole drugs.Additionally,echinocandins resistance has emerged in Candida albicans,Candida glabrata,Candida tropicalis,and Candida parapsilosis.

Objective:To investigate the relative expression level and clinical significance of LINC00475 in serum of patients with multiple myeloma(MM).Methods:The expression of LINC00475 in serum of 108 MM patients and five MM cell lines including RPMI 8226,NCI-H929,U266,OPM2 and CAG were detected by real-time fluorescence quantitative PCR.The diagnostic value of LINC00475 in MM was evaluated by receiver operating characteristic(ROC)curve analysis.The correlation of LINC00475 with patients'characteristics was analyzed.Results:Compared with control groups,the expression of LINC00475 was up-regulated in serum of MM patients and MM cell lines(all P＜0.05).ROC curve analysis showed that the optimal cut-off value of LINC00475 was 262.4,the area under curve(AUC)was 0.924(95％CI:0.884-0.964),and sensitivity and specificity was 83.3％and 91.7％,respectively,which indicated that LINC00475 had good evaluation value in MM patients.Compared with low-LINC00475 expression group,patients in high-LINC00475 expression group had higher levels of β2-microglobulin(β2-MG)and Cystatin C(Cys-C)but lower albumin(ALB)(all P＜0.05).Compared with MM patients with International Staging System(ISS)stage I,the expression level of LINC00475 was significantly higher in patients with stage Ⅱ and Ⅲ(both P＜0.05).Conclusion:LINC00475 is helpful to distinguish MM patients from healthy adults,which is correlated with the prognostic indicators such as β2-MG,ALB,and ISS stage.

Objective:To explore the changes in entero-insular axis function and its role in mice with severe burns.Methods:This study was an experimental study. Ninety C57BL/6J male mice aged 8-10 weeks were divided into sham injury group and burn group (with 45 mice in each group) according to the random number table. A full-thickness scald (hereinafter referred to as burn) wound of 30% of the total body surface area was created on the back of mice in burn group, and the mice in sham injury group were simulated to cause a sham injury. Twenty-four hours after injury, the fasting blood glucose was measured ( n=12), followed by intraperitoneal glucose tolerance test and oral glucose tolerance test; the curve of blood glucose concentration changes over time was plotted, and the area under the curve was calculated ( n=6); the blood was taken from the heart before intraperitoneal injection or gavage of glucose solution and at 30, 60, and 120 minutes after intraperitoneal injection or gavage of glucose solution for measuring the plasma insulin and glucagon like peptide-1 (GLP-1) levels using enzyme-linked immunosorbent assay (ELISA), with a sample number of 3; the ileal tissue was taken from 3 mice in each group for detecting the GLP-1 expression and apoptosis levels of intestinal L cells by immunofluorescence staining and TdT-mediated dUTP nick-end labeling staining; the pancreatic islets were collected from 6 mice in each group for glucose-stimulated insulin secretion experiments. After incubation with low glucose (2.8 mmol/L glucose) and high glucose (16.7 mmol/L glucose), the supernatant was taken and the insulin level was detected using ELISA. Thirty-six C57BL/6J male mice aged 8-10 weeks were divided into sham injury group, burn group, and burn+exendin-4 (Ex-4) group (with 12 mice in each group) according to the random number table. The mice in sham injury group and burn group were subjected to the same corresponding treatment as before. The mice in burn+Ex-4 group were injured in the same way as the burn group mice followed by treatment with GLP-1 receptor agonist Ex-4. Twenty-four hours after injury, mouse pancreatic islets were collected, the protein expressions of heavy-chain binding protein (BIP), protein kinase R-like endoplasmic reticulum kinase (PERK), phosphorylated PERK (p-PERK), eukaryotic translation initiation factor 2α (eIF2α), phosphorylated eIF2α (p-eIF2α), and CCAAT/enhancer-binding protein homologous protein (CHOP) were detected using Western blotting, and the p-PERK/PERK and p-eIF2α/eIF2α ratios were calculated ( n=3), the apoptosis rate of pancreatic islet cells was detected using flow cytometry ( n=3), the glucose stimulated insulin secretion experiment was conducted as before to detect insulin levels in the supernatant ( n=6). Results:Twenty-four hours after injury, the fasting blood glucose of mice in burn group was (7.3±1.0) mmol/L, which was significantly higher than (5.1±0.6) mmol/L in sham injury group ( t=6.36, P<0.05). Twenty-four hours after injury, in the intraperitoneal glucose tolerance test and oral glucose tolerance test, the areas under the curve of blood glucose concentration changes over time of mice in burn group were significantly larger than those in sham injury group (with t values of 4.32 and 6.03, respectively, P<0.05); compared with those in sham injury group, the plasma insulin levels of mice before intraperitoneal injection of glucose solution and the plasma GLP-1 levels of mice before intraperitoneal injection or gavage of glucose solution in burn group were significantly decreased ( P<0.05), and the plasma levels of insulin of mice at 30, 60, and 120 minutes after intraperitoneal injection or gavage of glucose solution, as well as the plasma levels of GLP-1 of mice at 30 and 60 minutes after gavage of glucose solution were significantly decreased in burn group ( P<0.05). Twenty-four hours after injury, compared with those in sham injury group, the GLP-1 expression level of intestinal L cells of mice in burn group was significantly decreased ( t=7.74, P<0.05), and the apoptosis level was significantly increased ( t=14.28, P<0.05). Twenty-four hours after injury, the insulin level in the supernatant of mice pancreatic islet incubated with high glucose in burn group was (8.5±0.4) ng/mg, which was significantly lower than (15.7±0.3) ng/mg in sham injury group ( t=18.68, P<0.05). Twenty-four hours after injury, compared with those in sham injury group, the protein expression levels of BIP, p-PERK/PERK, p-eIF2α/eIF2α, and CHOP in the pancreatic islets of mice in burn group were significantly increased ( P<0.05); compared with those in burn group, the protein expression levels of BIP, p-PERK/PERK, p-eIF2α/eIF2α, and CHOP in the pancreatic islets of mice in burn+Ex-4 group were significantly decreased ( P<0.05). Twenty-four hours after injury, the apoptosis rate of pancreatic islet cells of mice in burn group was (32.0±3.0)%, which was significantly higher than (10.3±2.5)% in sham injury group ( P<0.05); the apoptosis rate of pancreatic islet cells of mice in burn+Ex-4 group was (20.0±3.6)%, which was significantly lower than that in burn group ( P<0.05). Twenty-four hours after injury, the insulin level in the supernatant of mice pancreatic islet incubated with high glucose in burn group was significantly lower than that in sham injury group ( P<0.05), while the insulin level in the supernatant of mice pancreatic islet incubated with high glucose in burn+Ex-4 group was significantly higher than that in burn group ( P<0.05). Conclusions:After severe burns, the mice display dysfunction of the entero-insular axis, increased apoptosis of intestinal L cells, decreased synthesis and secretion of GLP-1, endoplasmic reticulum stress and increased apoptosis in pancreatic islet cells and a decrease in glucose-stimulated insulin secretion. The GLP-1 receptor agonist Ex-4 can protect the function of pancreatic islet cells of mice with severe burns, reducing the apoptosis level of pancreatic islet cells and promoting insulin secretion possibly via the alleviation of endoplasmic reticulum stress.

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.

Influenza virus causes serious threat to human life and health. Due to the inherent high variability of influenza virus, clinically resistant mutant strains of currently approved anti-influenza virus drugs have emerged. Therefore, it is urgent to develop antiviral drugs with new targets or mechanisms of action. RNA-dependent RNA polymerase is directly responsible for viral RNA transcription and replication, and plays key roles in the viral life cycle, which is considered an important target of anti-influenza drug design. From the point of view of medicinal chemistry, this review summarizes current advances in diverse small-molecule inhibitors targeting influenza virus RNA-dependent RNA polymerase, hoping to provide valuable reference for development of novel antiviral drugs.
