Objective:To investigate the clinical data, drug resistance and treatment prognosis of Cryptococcus neoformans isolated from patients with acquired immunodeficiency syndrome(AIDS) in a hospital in Shanghai. Methods:The clinical data of AIDS patients with Cryptococcus neoformans infection in Shanghai Public Health Clinical Center from January 2014 to December 2023, and the drug sensitivity to 5 antifungal drugs in vitro, treatment and prognosis were retrospectively analyzed. Results:From January 2014 to December 2023, there were 295 AIDS patients with Cryptococcus neoformans infection in our hospital, with 255 males and 40 females. CD4 + T lymphocyte counts ≤100 cells/μl were detected in 251 patients. A total of 384 strains of Cryptococcus neoformans were isolated from the 295 patients, with the highest detection rate in cerebrospinal fluid samples (65.9%, 253/384), followed by blood samples (29.4%, 113/384). The sensitivity of 384 strains of Cryptococcus neoformans to 5-fluorocytosine was the highest (98.5%, 379/384), followed by fluconazole (95.6%, 367/384) and amphotericin B (95.3%, 366/384). After treatment against cryptococcal infection, 252 patients (86.0%, 252/293) were discharged and 20 patients (6.8%, 20/293) died. The other 2 cases were not treated for cryptococcal infection. Conclusions:As Cryptococcus neoformans is an important pathogen of AIDS patients, clinicians should actively carry out laboratory examination of Cryptococcus and rational drug use according to the results of drug sensitivity test, while alert to the occurrence of drug resistance.

Objective: To identify the core symptoms and bridge symptoms in the network structure among adolescents bullying victimization, anxiety and depressive symptoms, and to explore the interrelationships among these three variables, so as to provide a basis for the precise prevention of bullying behaviors and the improvement of adolescents psychological health conditions. Methods: From October to November 2023, a stratified cluster random sampling method was employed to select 4 759 middle and high school students from four cities in Guangxi: Beihai, Guigang, Hechi, and Laibin. The Chinese version of the Olweus Bully/Victim Questionnaire (OBVQ) was used to assess bullying victimization among adolescents, while the Generalized Anxiety Disorder-7 (GAD-7) and the Patient Health Questionnaire-9 (PHQ-9) were utilized to assess anxiety and depressive symptoms, respectively. The Bootnet package (version 1.6) in R software (version 4.4.1) was used to construct a network structure and analyze the associations between bullying victimization, anxiety symptoms and depressive symptoms among adolescents. Results: The reporting rates of depressive symptoms, anxiety symptoms, and bullying victimization among adolescents in Guangxi were 24.67%, 16.33%, and 16.58%, respectively. Network analysis revealed that the node with the highest expected influence was "property being taken or damaged", with a standardized expected influence (EI) index of 2.09. The top two nodes in terms of bridge expected influence were "thoughts of self harm or suicide" and "irritability", with standardized bridge expected influence (BEI) indices of 2.15 and 1.27, respectively. The stronger associations were observed between the node "property being taken or damaged" and the nodes "physical attacks such as hitting, kicking, pushing, or shoving" and "ridiculed due to accent", with edge weights of 0.43 and 0.35, respectively. Conclusion Targeting preventive measures against the symptoms with the highest expected influence and bridge expected influence in the network of bullying victimization, anxiety and depressive symptoms among adolescents may be an effective approach to reduce the negative impact of bullying victimization, anxiety and depressive symptoms on adolescents.

Objective To investigate the awareness of female patients with pelvic floor dysfunction regarding minimally invasive laser treatment of the reproductive tract and analyze the factors influencing their decision-making intentions,this study aims to provide a foundation for early treatment of pelvic floor dysfunction and further development in reproductive health management.Methods A convenience sampling method was employed to select 164 female patients with pelvic floor dysfunction who sought treatment at the Pelvic Rehabilitation Center of Dongguan Maternal and Child Health Care Hospital between June 2023 and August 2024.The study utilized the Female Sexual Function Index,Incontinence Quality of Life Questionnaire,and Family Support Self-Assessment Scale to conduct a survey.Binary logistic stepwise regression analysis was conducted to investigate the factors influ-encing patients'inclination towards undergoing genital laser minimally invasive treatment.Results Among the 164 female patients,143(87.2%)expressed an intention to receive treatment,with 22.6%demonstrating a rela-tively clear understanding of genital laser minimally invasive treatment.Logistic regression analysis revealed that occupation significantly influenced treatment intention(P<0.05).Compared to healthcare professionals,individuals in the teaching profession(OR=10.81,95%CI:1.04～112.21),self-employed individuals(OR=20.34,95%CI:3.46～119.43),and those in other professions(OR=16.26,95%CI:4.05～65.29)were more inclined to express willingness for undergoing treatment.Furthermore,a lower score on the Incontinence Quality of Life scale was found to positively correlate with treatment intention(OR=0.96,95%CI:0.93～0.99).Conclusion Although patients express a high intention to undergo minimally invasive genital laser treatment,their overall awareness of the procedure remains insufficient.

Objective: To investigate the characteristics of newly reported HIV/AIDS cases aged 15 years and older in Shangcheng District, Hangzhou City from 2006 to 2022, so as to provide the basis for improving AIDS prevention and control strategies. Methods: Data of newly reported HIV/AIDS cases aged 15 years and older in Shangcheng District from 2006 to 2022 were collected through HIV/AIDS Comprehensive Control System of Chinese Disease Prevention and Control Information System. Population distribution and transmission routes were analyzed, and changing trends in case number were analyzed using average annual percent change (AAPC) and annual percent change (APC). Results: A total of 4 409 HIV/AIDS cases aged 15 years and older were newly reported in Shangcheng District from 2006 to 2022, including 3 932 males (89.18%). There were 3 447 cases (78.18%) under 50 years old and 962 cases (21.82%) being 50 years and older. Sexual contact was a predominant transmission route, with 4 326 cases accounting for 98.12%, including 2 626 cases (59.56%) with homosexual contact and 1 700 cases (38.56%) with heterosexual contact. The number of HIV/AIDS cases showed an overall upward trend from 2006 to 2022 (AAPC=13.038%, P<0.05), with an upward trend from 2006 to 2015 (APC=42.578%, P<0.05) and a downward trend from 2015 to 2022 (APC=-19.713%, P<0.05). The increase in the number of cases aged 50 years and older group was faster than that of cases aged under 50 years (AAPC=22.641% vs. 11.162%, both P<0.05). The increase in the number of cases with homosexual contact transmission was faster than that of cases with heterosexual contact transmission (AAPC=20.417% vs. 7.455%, both P<0.05). Conclusions The number of newly reported HIV/AIDS cases aged 15 years and older in Shangcheng District performed an overall upward trend from 2006 to 2022. The cases aged 50 years and older and transmitted through homosexual contact increased rapidly, which should be taken seriously.

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.

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.

In this study, we presented the isolation and characterization of eight novel seco-guaianolide sesquiterpenoids (1-8) and two known guaianolide derivatives (9 and 10), from the aerial part of Achillea alpina L.. Compounds 1-3 were identified as guaianolides bearing an oxygen insertion at the 2, 3 position, while compounds 4-8 belonged to a group of special 3-nor guaianolide sesquiterpenoids. The structural elucidation of 1-8, including their absolute configurations, were accomplished by a combination of spectroscopic data analysis and quantum electronic circular dichroism (ECD) calculations. To evaluate the potential antidiabetic activity of compounds 1-10, we investigated their effects on glucose consumption in palmitic acid (PA)-mediated HepG2-insulin resistance (IR) cells. Among the tested compounds, compound 7 demonstrated the most pronounced ability to reverse IR. Moreover, a mechanistic investigation revealed that compound 7 exerted its antidiabetic effect by reducing the production of the pro-inflammatory cytokine IL-1β, which was achieved through the suppression of the NLRP3 pathway.

Sepsis is a complex syndrome caused by multiple pathogens and involves multiple organ failure, particularly spleen dysfunction. In 2017, the worldwide incidence was 48.9 million sepsis cases and 11 million sepsis-related deaths were reported (Rudd et al., 2020). Inflammation, oxidative stress, and apoptosis are the most common pathologies seen in sepsis. Liensinine (LIE) is a bisbenzylisoquinoline-type alkaloid extracted from the seed embryo of Nelumbo nucifera. Lotus seed hearts have high content of LIE which mainly has antihypertensive and antiarrhythmic pharmacological effects. It can exert anti-carcinogenic activity by regulating cell, inflammation, and apoptosis signaling pathways (Manogaran et al., 2019). However, its protective effect from sepsis-induced spleen damage is unknown. In this research, we established a mouse sepsis model induced by lipopolysaccharide (LPS) and investigated the protective effects of LIE on sepsis spleen injury in terms of inflammatory response, oxidative stress, and apoptosis.
