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 correlation between neuropeptide S receptor(NPSR)single nucleotide polymorphism(SNP)(rs323917,rs323920,rs323922,rs2530547,rs324957)and primary insomnia(PI).Methods A total of 157 patients diagnosed with PI in the outpatient department of Center of Sleep Medicine,Gansu Provincial People's Hospital from December 2016 to May 2019 were selected as PI group,and 133 healthy physical examination subjects during the same period were selected as control group.Venous blood samples were collected and DNA,polymerase chain reaction(PCR)amplification and agarose gel electrophoresis were extracted.rs323917,rs323920,rs323922,rs2530547,rs324957 single nucleotide loci were genotypized by target site sequencing.Meanwhile,standard polysomnosis monitoring was performed to analyze the correlation between gene polymorphism and PI.Results There were no significant differences in the genotype distribution of NPSR SNP sites(rs323917,rs323920,rs323922,rs2530547)and allele frequency and rs324957 allele frequency between two groups(P＞0.05).There was significant difference in genotype distribution of rs324957(P=0.034).There was no significant difference in the frequency of different haplotypes between two groups(P＞0.05).Conclusion The expression of rs324957 SNP genotypes in NPSR may be related to PI,and AG genotype is dominant.

Objective:To explore the longitudinal changes of symptom clusters and quality of life in young and middle-aged postoperative patients with cervical cancer during chemotherapy, and to clarify the correlation between the two, in order to provide reference for clinical staff symptom management and improvement of patients′ quality of life.Methods:A longitudinal study was conducted, a total of 252 young and middle-aged who underwent chemotherapy after radical cervical cancer surgery in the gynecological ward of Henan Provincial People′s Hospital from December 2022 to August 2023 were selected as the investigation objects by convenient sampling method. Data were collected at 2 d before chemotherapy (T1), 1 week after the first chemotherapy (T2), 1 week after the third chemotherapy (T3), and 1 week after the sixth chemotherapy (T4), using the general data questionnaire, the Chinese version of the Memorial Symptom Assessment Scale and the Functional Assessment of Cancer Therapy-Cervix. Exploratory factor analysis was used to extract symptom clusters from the data. The generalized estimation equation model was used to analyze the dynamic change trend and correlation between symptom clusters and quality of life.Results:A total of 221 patients with cervical cancer aged 18-59 (46.85 ± 6.50) years old were included. At T1 and T2, there were 4 symptom clusters, which were psychological symptom cluster, gastrointestinal symptom cluster, disease behavior symptom cluster and perimenopausal symptom cluster. T3 and T4 increased the neurological symptom cluster and self-image disorder symptom cluster, a total of 6 symptom clusters. The higher score of each symptom cluster, the lower total score of quality of life (Wald χ2 values were 8.08-62.70, all P<0.01). Conclusions:Young and middle-aged postoperative patients with cervical cancer suffered from multiple symptom clusters during chemotherapy, which not only remained relatively stable, but also showed a constantly changing trend. Effective dynamic management of symptoms clusters in young and middle-aged postoperative patients with cervical cancer during chemotherapy is expected to improve their quality of life.

Objective To investigate the association between abdominal visceral fat content and the occur-rence of type 2 diabetes mellitus(T2DM)and the potential of predicting the incidence of T2DM with abdominal visceral fat content.Methods The study included 45 patients with T2DM who underwent 3.0T MRI and 80 control patients,recruited from the First Affiliated Hospital of Baotou Medical College,Inner Mongolia University of Science and Technology.IDEAL software was utilized for automated image recombination to obtain fat fraction,relaxation rate(R2*),lipid phase,water phase,and in-phase images.Fat fraction images were transferred to AW 4.6 workstation for measurement of fat fraction plots by two observers using a double-blind approach.ITK-SNAP software was employed for semi-automatic delineation of abdominal visceral fat and subcutaneous adipose tissue through threshold segmentation method,followed by volume calculation.Statistical analysis of the data was performed using SPSS 26.0 software.Results(1)The T2DM group exhibited significantly higher levels of abdominal visceral adipocyte volume(VATV),hepatic fat fraction(HFF),pancreatic fat fraction(PFF),triglyceride(TG),and fasting blood glucose(FBG)compared to the control group.Conversely,the high density lipoprotein(HDL)level was significantly lower in the T2DM group than in the control group(P＜0.05).The correlation analysis revealed that in male patients,abdominal VATV exhibited positive associations with body mass index(BMI),waist circumference,subcutaneous adipose tissue volume(SATV),hepatic fat fraction(HFF),TG,and FBG;while displaying a negative association with HDL.In female patients,VATV demonstrated positive correlations with BMI,waist circumference,SATV,and HFF.(2)The ROC curve analysis demonstrated that the area under the curve(AUC)for PFF in diagnosing T2DM was 0.656(P＜0.01,95%CI:0.534～0.777).The determined cut-off value was 8.44%,yielding a sensitivity of 50%and specificity of 82.5%.Similarly,HFF exhibited an AUC of 0.744(P＜0.05,95%CI:0.637～0.851),with a cut-off value of 2.99%,sensitivity of 97.5%,and specificity of 42%.In male patients,VATV displayed an optimal threshold for T2DM diagnosis at a volume of approximately 3 466 cm3,resulting in a sensitivity of 63.2%,specificity of 89.5%,and AUC of 0.78(P＜0.01).The sensitivity was 78.9%and specificity was 84.2%when SATV,PFF and HFF were combined and the AUC was 0.839(P＜0.01).The optimal threshold for diagnosing T2DM with VATV in female patients was 2 103cm3,and the sensitivity,specificity and AUC of T2DM with VATV were 66.7%,66.7%and 0.68(P＜0.05).When SATV,PFF and HFF were combined,the sensitivity was 90.5%.The specificity was 76.2%and the AUC was 0.909(P＜0.01).(3)For each additional unit of TG and FBG,the risk of T2DM respectively increased by 3986.3%and 417.1%,in other words,TG and FBG were independent predictors of the occurrence of T2DM.Conclusion The predictive value of pancreatic fat fraction,liver fat fraction,and abdominal visceral fat tissue volume for the onset of type 2 diabetes is limited.However,combining abdominal visceral adipose tissue volume with subcutaneous adipose tissue volume,pancreatic fat fraction,and liver fat fraction significantly enhances the efficacy,sensitivity,and specificity of predicting type 2 diabetes occurrence.The IDEAL-IQ technique offers a convenient method for quantitatively evaluat-ing intra-abdominal ectopic adipose tissue deposition in patients with type 2 diabetes mellitus.It demonstrates advantages such as simplicity,good stability,high reproducibility and holds great potential.

Objective:To explore the predictive value of the prognostic nutritional index (PNI) in concurrently infected patients with acute-on-chronic liver failure (ACLF).Methods:220 cases with ACLF diagnosed and treated at the First Affiliated Hospital of Xi'an Jiaotong University from January 2011 to December 2016 were selected. Patients were divided into an infection and non-infection group according to whether they had co-infections during the course of the disease. Clinical data differences were compared between the two groups of patients. Binary logistic regression analysis was used to screen out influencing factors related to co-infection. The receiver operating characteristic curve was used to evaluate the predictive value of PNI for ACLF co-infection. The measurement data between groups were compared using the independent sample t-test and the Mann-Whitney U rank sum test. The enumeration data were analyzed using the Fisher exact probability test or the Pearson χ2 test. The Pearson method was performed for correlation analysis. The independent risk factors for liver failure associated with co-infection were analyzed by multivariate logistic analysis. Results:There were statistically significant differences in ascites, hepatorenal syndrome, PNI score, and albumin between the infection and the non-infection group ( P ?

Hyperpolarization-activated cyclic nucleotide-gated(HCN)channels are widely expressed in the central and peripheral nervous systems.They can generate hyperpolarization-activated current(Ih)that regulates the resting membrane potential and excitability of neurons.Furthermore,it can affect the precise processing and con-duction of hearing,which plays a crucial role in the accurate analysis of temporal information.Therefore,through the review of HCN channel structure and distribution,as well as electrophysiological effects,the role and mecha-nism of HCN channels in the auditory pathways of the normal and unilateral or bilateral deafness patients will be fur-ther investigated.

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.

Diabetic ulcer （DU） wound is one of the chronic and serious complications of diabetes characterized by prolonged wound healing， and it is more common in foot and lower extremity ulcers. DU has brought great economic and psychological pressure to patients and seriously affected the quality of life of patients because of its great difficulty in treatment， long treatment process， and high morbidity and mortality. Therefore， how to help the rapid healing of DU wounds， reduce the disability rate and mortality rate， protect limb function， and improve the quality of life is an important topic and hot spot in the field of medical research. The pathogenesis of DU is complex， mainly including microcirculation disorder， peripheral neuropathy， inflammation and infection， and excessive apoptosis of cells， involving physiological processes such as wound inflammation， granulation tissue hyperplasia and re-epithelialization. A large number of previous studies have found that Chinese medicine can regulate phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt）， Wnt/β-catenin， nuclear factor-κB （NF-κB）， Notch， nuclear factor E₂-related factor 2 （Nrf2）， transforming growth factor-β （TGF-β）/Smad， and other signaling pathways， regulate abnormal glucose metabolism， improve microcirculation， inhibit inflammation and oxidative stress， regulate cell proliferation and excessive apoptosis， and promote wound tissue growth to promote the rapid healing of DU wounds under the guidance of treatment based on traditional Chinese medicine （TCM） syndrome differentiation and internal and external treatment. Therefore， this paper reviewed Chinese medicinal monomers or Chinese medicinal compounds in recent years in regulating the above signaling pathways and the expression of key protein molecules and promoting the rapid healing of DU wounds， aiming to provide ideas and a theoretical basis for the in-depth study and clinical application of Chinese medicine in promoting the healing of DU wounds.

Objective To explore the prevention and treatment of vasovagal reflex during and after operation in diseases of urinary system.Methods From February 2020 to April 2023,1436 patients who completed inpatient surgery in Department of Urology,Songshan Hospital,Qingdao University Medical College were selected to analyze the emergency management measures of vasovagal reflex during and after operation and summarize the diagnosis and treatment experience.Results Among 1436 patients,vasovagal reflex occurred in 4 cases during operation and 14 cases after operation,with an incidence of 1.25%.Most patients showed simultaneous decrease in blood pressure and heart rate.After intravenous injection of atropine and dopamine,blood pressure and heart rate returned to normal,and various concomitant symptoms disappeared,and no death cases were reported.Conclusion Urological specialists should pay attention to vasovagal reflex,sum up experience,do early identification,timely treatment to ensure the safety of patients.

Lung cancer is the top cause of cancer deaths globally.Advances in immune checkpoint inhibitors(ICIs)have transformed cancer treatment,but their use in lung cancer has led to more side effects.This study examined if past pulmonary tuberculosis(TB)affects ICIs'effectiveness and safety in lung cancer treatment.We reviewed lung cancer patients treated with ICIs at Beijing Chest Hospital from January 2019 to August 2022.We compared outcomes and side effects between patients with and without prior TB.Of 116 patients(40 with TB history,76 without),prior TB didn't reduce treatment effectiveness but did increase severe side effects.Notably,older patients(≥65 years)faced a higher risk of severe side effects.Detailed cases of two patients with severe side effects underscored TB as a risk factor in lung cancer patients receiving ICIs,stressing the need for careful monitoring and personalized care.
