Objective:To investigate the effect of laparoscopic splenectomy and azygoportal disconnection (LSD) on liver synthesis and development of liver cirrhosis.Methods:This is a prospective case series study.The clinical data of liver cirrhotic patients with portal hypertension who received LSD at the Department of Hepatobiliary Surgery of Northern Jiangsu People′s Hospital Affiliated to Yangzhou University from September 2014 to January 2016 were included. This study analyzed the diameter of the portal vein, the velocity of portal blood flow, the routine blood parameters, the liver function, the synthetic proteins of liver (antithrombin Ⅲ (AT-Ⅲ), protein S, protein C), and the serum content of liver fibrotic markers(collagen type Ⅳ, procollagen type Ⅲ, laminin, hyaluronidase). Repeated measures ANOVA was used for comparison between multiple groups, and least significance difference was used for post-hoc multiple comparison.Results:A total of 106 patients were included in the study, including 70 males and 36 females, aged (51.8±9.8) years(range: 28 to 75 years).Compared with the preoperative results, the diameter of portal vein and the velocity of portal vein decreased after surgery ( F=14.03, 12.15, respectively, both P<0.01). Compared with the preoperative results, the total bilirubin, albumin, prothrombin time, international normalized ratio, Child-Pugh score and classification were improved ( F=17.96, 56.01, 66.63, 35.83, 33.49, and 27.50, respectively, all P<0.01), and the AT-Ⅲ, protein S, protein C,collagen type Ⅳ, procollagen type Ⅲ, laminin and hyaluronidase levels were also improved ( F=47.87, 36.26, 18.02, 2.79, 14.58, 44.35, and 14.38, respectively, all P<0.01). Compared with the preoperative period, the diameter of portal vein was reduced from the first week to the 24 th month after surgery ( t=5.45 to 9.39, all P<0.01). Compared with the preoperative period, the velocity of portal vein blood from the first week after surgery to the 24 th month after surgery was decreased ( t=4.02 to 8.43, all P<0.01). Compared with the preoperative period, routine blood parameters (white blood count, hemoglobin, platelet count), liver function (total bilirubin, albumin, prothrombin time, international normalized ratio, Child-Pugh score), liver synthetic protein (AT-Ⅲ, protein S, protein C) and liver fibrotic markers (collagen type Ⅳ, procollagen type Ⅲ, laminin, hyaluronidase) were improved to varying degrees at the 24th month after surgery ( t=-20.46 to 11.93, all P<0.01). Conclusion:Preliminary findings show that LSD can reduce portal vein pressure, restore blood cell number, and improve liver synthesis function and the degree of liver fibrosis in patients with portal hypertension in liver cirrhosis.

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.

Background and purpose:The overexpression of carnitine palmitoyl transferase 1A(CPT1A)is related to the poor prognosis of breast cancer,and it can promote the utilization of fatty acids by mitochondria and maximize triphosphate(ATP)production.However,the role of CPT1A in breast cancer metastasis is still unclear.This study aimed to explore the mechanism that mitochondrial dysfunction and CPT1A/extracellular signal-regulated kinase(ERK)signaling pathway in breast cancer jointly regulate the malignant behavior of breast cancer.Methods:The lentivirus system and shRNA tools were used to overexpress or knock down CPT1A in human breast cancer cell lines MDA-MB-231 and MCF7,and the cells were divided into NC group,CPT1A group and shCPT1A group.The invasion ability of cells was detected by transwell assay,and the protein expressions of peroxisome proliferator-activated receptor γ coactivator-1α(PGC-1α),ERK1/2 and CPT1A were analyzed by Western blot.The mitochondrial morphology of MDA-MB-231 and MCF7 cell lines was analyzed using mitochondrial red staining,and mitochondrial respiratory capacity was analyzed by oxygen consumption rate.Results:Compared with cells expressing control vector,overexpression of CPT1A resulted in enhanced invasion abilities of MCF7 cells and MDA-MB-231 cells(P＜0.05),while knockdown of shCPT1A resulted in decreased invasion abilities of cells(P＜0.05).Compared with NC group,the length of mitochondrial branches in MDA-MB-231 and MCF7 cells in CPT1A group was significantly shorter(P＜0.05),and the expressions of ERK1/2 and PGC-1α increased significantly(P＜0.05).In shCPT1A group,the length of mitochondrial branches in MDA-MB-231 and MCF7 cells increased significantly(P＜0.05),and the expressions of ERK1/2 and PGC-1α decreased significantly(P＜0.05).In addition,compared with NC group,the cellular basis,maximum respiratory capacity and ATP production of MDA-MB-231 in CPT1A group increased significantly(P＜0.05),while the cellular basis,maximum respiratory capacity and ATP production of MDA-MB-231 in shCPT1A group decreased significantly(P＜0.05).Conclusion:ERK1/2-PGC-1α activated by CPT1A Signaling pathway plays a key role in mitochondrial division mediated breast cancer cell metastasis.

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:To identify the development trajectories of self-neglect behavior in older adults and explore the associated influencing factors.Methods:A fixed cohort was constructed based on the data from three surveys of Chinese longitudinal healthy longevity survey (CLHLS) from 2011 to 2018. A total of eight variables from 4 dimensions including living environment, lifestyle, social interaction, and health care were selected to evaluate self-neglect. Group-based trajectory model was used to identify the development trajectory of self-neglect behavior in the older adults, and polynomial Logistic regression model was used to explore its influencing factors by Stata 16.1.Results:Finally, 2 754 older adults aged 60 and above were included.The development trajectory of self-neglect behavior in older adults, based on the group-based trajectory model, can be classified into stable-low group ( n=268, 9.7%), descending-moderate group ( n=2 224, 80.8%), and decreasing-high group ( n=262, 9.5%). Polynomial Logistic regression showed that, compared with stable-low group, living in rural areas ( B=1.116, OR=3.053, 95% CI= 2.278-4.091) and higher activities of daily living scores( B=0.137, OR=1.147, 95% CI=1.046-1.258) were the risk factors of descending-moderate group. Education levels with 1-6 years( B=-0.398, OR=0.672, 95% CI=0.469-0.963), >6 years( B=-1.072, OR=0.342, 95% CI=0.229-0.513), being married( B=-0.476, OR=0.621, 95% CI=0.444-0.870), self-reported good health( B=-0.808, OR=0.446, 95% CI= 0.213-0.932), improved health status( B=-0.704, OR=0.495, 95% CI=0.320-0.766), self-reported average economic status( B=-1.065, OR=0.345, 95% CI=0.148-0.802), self-reported good economic status( B=-1.634, OR=0.195, 95% CI=0.082-0.467), and a higher cognition score( B=-0.142, OR=0.867, 95% CI=0.798-0.942) served as protective factors of descending-moderate group. In addition to the above factors, being in the age group of 75-89 years( B=0.481, OR=1.617, 95% CI=1.057-2.473) was a risk factor for decreasing-high group compared to stable-low group. Conclusions:Three types of self-neglect behavior trajectories among older adults were identified in this study, suggesting that physical health and economy are the influencing factors of the development trajectory of self-neglect of the elderly.

Objective:To compare the recurrence of common bile duct stones (CBDS) in patients with gallstones and concurrent CBDS treated by two surgical approaches: synchronous laparoscopic cholecystectomy (LC) combined with laparoscopic common bile duct exploration (LCBDE) (LC+LCBDE) and synchronous LC combined with intraoperative endoscopic sphincterotomy (IO-EST) (LC+IO-EST).Methods:From Apr 2013 to Apr 2020, the clinical data of 903 patients with gallstones with CBDS who were admitted to the Clinical Medical College, Yangzhou University were retrospectively analyzed.Results:Based on the chosen surgical method, we categorized 389 cases into group A (LC+LCBDE) and 514 cases into group B (LC+IO-EST). Our findings revealed that group A had a significantly lower rate of CBDS recurrence and re-recurrent CBDS compared to group B (4.4% vs. 8.4%, P=0.024; 0.8% vs. 3.1%, P=0.010). Moreover, Logistic regression analysis after inverse probability of treatment weighting, revealed that the surgical approach implemented in group A was an independent protective factor of recurrent CBDS and second recurrence of CBDS ( OR=0.482, 95% CI: 0.365-0.637, P<0.001; OR=0.118, 95% CI:0.080-0.173, P<0.001). Conclusion:LC+LCBDE is an optimal treatment option to LC+IO-EST for patients with gallstones combined with CBDS and common bile duct ≥8 mm.

Background Sleep disturbances in children and adolescents have become a global public health concern,with pronounced issues in the Western China.Despite this,research on the prevalence of insomnia and its influencing factors among children and adolescents in Chongqing is still lacking.Objective To understand the prevalence of insomnia and analyze its influencing factors among children and adolescents in Chongqing,so as to provide references for clinical interventions and preventive strategies of insomnia.Methods A stratified random sampling method was used to select 9 969 children and adolescents in Chongqing from November to December 2021.Insomnia Severity Index(ISI)and a self-designed questionnaire on awareness of core mental health knowledge were administered.Binary Logistic regression analysis was used to identify the influencing factors of insomnia in this population.Results A total of 3 578 children and adolescents(35.89％)were found to have insomnia symptoms.There were statistically significant differences in the detection of insomnia symptoms among gender,ethnicity,education level,domicile,only-child status,parental education level,introversion/extroversion,parental relationship,average monthly per capita income,family history of mental illness,medical insurance coverage,living situation and understanding of mental health knowledge(P<0.05 or 0.01).Binary Logistic regression analysis identified several risk factors for insomnia,including female gender(OR=1.301,95％CI:1.192～1.419),ethnic minority status(OR=1.163,95％CI:1.015～1.333),junior high school for education level(OR=1.985,95％CI:1.774～2.220),senior high school for education level(OR=3.085,95％CI:2.749～3.462),non-only-child status(OR=1.127,95％CI:1.013～1.253),degree of harmony between parents is not high or not harmonious[(OR=1.846,95％CI:1.669～2.041 for relatively harmonious;OR=2.524,95％CI:2.214～2.877 for generally harmonious;OR=2.452,95％CI:1.999～3.007 for not very harmonious;OR=2.926,95％CI:2.307～3.710 for very discordant)]and incomplete medical insurance coverage(OR=1.218,95％CI:1.093～1.358).Protective factors included an extroverted personality(OR=0.838,95％CI:0.766～0.917),absence of family history of mental illness(OR=0.719,95％CI:0.549～0.941),junior high school for mother's education level(OR=0.822,95％CI:0.734～0.920),senior high school or secondary specialized school for mother's education level(OR=0.862,95％CI:0.752～0.988),college and above for mother's education level(OR=0.748,95％CI:0.633～0.884)and knowledge of mental health(OR=0.854,95％CI:0.778～0.937).Conclusion The problem of insomnia among children and adolescents in Chongqing is quite serious.Risk factors for insomnia include female gender,ethnic minority status,higher education levels,being a non-only child,poor family relationships and incomplete medical insurance.Conversely,an extroverted personality,absence of family history of mental illness,higher maternal education and knowledge of mental health serve as protective factors against insomnia.

AIM:To observe how total flavonoids of Pterocarya hupehensis Skan(PHSTF)affects the migra-tion and invasion of human rheumatoid fibroblast-like synoviocyte line MH7A.METHODS:The MH7A cells were divided into control group(without any treatment),low-,medium-and high-dose(6.25,12.5 and 25 mg/L,respectively)PHSTF groups,phosphatidylinositol 3-kinase(PI3K)inhibitor 740Y-P(10 μmol/L)group,and 740Y-P(10 μmol/L)+high-dose(25 mg/L)PHSTF group.The viability of the MH7A cells was determined by CCK-8 assay,while the migration and inva-sion were assessed by scratch and Transwell assays.The protein levels of matrix metalloproteinase-2(MMP-2),MMP-9,PI3K,p-PI3K,AKT and p-AKT were detected by Western blot.RESULTS:Compared with control group,the cell via-bility in PHSTF treatment groups was reduced(P<0.05),the cell wound healing area was significantly decreased(P<0.01),migratory and invasive cells in the lower chamber were significantly reduced(P<0.01),and the protein expres-sion of MMP-2 and MMP-9 and the ratios of p-PI3K/PI3K and pAKT/AKT were decreased(P<0.01).Compared with high-dose PHSTF group,the addition of PI3K/AKT pathway agonist 740Y-P significantly increased the migration and invasion ability of MH7A cells(P<0.01)and elevated the protein expression of MMP-2 and MMP-9 and the ratios of p-PI3K/PI3K and pAKT/AKT(P<0.01)under the treatment with PHSTF.CONCLUSION:Total flavonoids of Pterocarya hupehensis Skan could inhibit the migration and invasion of MH7A cells by regulating the PI3K/AKT signaling pathway.
