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 retrospectively analyze of factors influencing early preterm birth(EPB)and late preterm birth(LPB)in pregnancy women with placenta previa complicated by placenta accreta spectrum disorders(PAS),and assess maternal and infant outcomes.Methods We included 590 cases of pregnancy women with placenta previa complicated by PAS who underwent cesarean sections at five hospitals in Wuhan and Xianning cities between January 2018 and June 2021.These patients were divided into three groups based on delivery gesta-tional age:EPB,LPB,and term birth(TB).A multiple logistic regression model was employed to analyze the risk factors associated with EPB and LPB.Additionally,differences in early maternal and infant outcomes among these groups were examined.Results Among 590 pregnancy women with placenta previa complicated by PAS,the proportions of EPB and LPB were 9.7%and 54.4%.The use of uterine contraction inhibitors prior to cesarean section,vaginal bleeding,and previous cesarean sections history were identified as risk factors for both EPB and LPB.The proportion of severe postpartum hemorrhage was comparable between the EPB group and the LPB group;however,the incidence of neonatal asphyxia,low birth weight infants,and the rate of newborns transferred to the Neonatal Intensive Care Unit(NICU)within 24 hours after cesarean delivery were significantly higher in the EPB group compared to the LPB group.Conclusions Placenta previa complicated by PAS predominantly leads to LPB.The history of prior cesarean sections,uterine contractions,and vaginal bleeding prior to cesarean section,are sig-nificantly associated with both EPB and LPB.During the perinatal period,efforts should be made to extend gesta-tional weeks under close monitoring to minimize the incidence of premature births and thereby improve early mater-nal and infant outcomes.

Objective To investigate the clinical effect and hearing loss of endolymphatic sac decompression(ESD)combined with one or two semicircular canal obstruction(SCO)in treating the patient with stage Ⅲ or stageⅣ Meniere disease.Methods Forty-three patients with stage Ⅲ or stage Ⅳ Meniere disease,who failed to respond to conventional conservative treatment and had the expectation of preserving residual hearing function,were enrolled in the study.They were divided into three groups according to the operation they underwent:ESD combined with lateral and posterior semicircular canal obstruction(ESD+LPSCO)13 cases,ESD combined with lateral semicircu-lar canal obstruction(ESD+LPSCO)14 cases,and ESD only 16 cases.Data of vertigo,ear fullness and tinnitus be-fore and after operation was collected,analyzed and compared.Hearing function before and after the operation was also evaluated.Results The number of vertigo attacks in the three groups(ESD+LPSCO,ESD+LSCO,and ESD)were all significantly reduced after operation.The vertigo control rate were 92.3％,78.6％and 62.5％re-spectively.Compared with pre-operation,the vertigo severity post-operation in the three groups were also signifi-cantly reduced.And the improvement rate of vertigo severity after ESD+LPSCO and ESD+LSCO were both 100％,which were significantly higher than that of ESD(68.8％).The discomfort of tinnitus and ear fullness in the three groups were significantly improved compared with that of pre-operation.The improvement rates of tinnitus in the three groups were 46.2％,50.0％and 43.8％respectively,with no significant difference.The improvement rate of ear fullness in the three groups were 61.5％,57.1％and 50.0％respectively,with no significant difference either.The proportion of patients with decreased hearing after operation in the three groups was 15.4％,7.1％and 18.8％,respectively,and the differences were insignificant.Conclusion ESD combined with one or two SCO can effectively control vertigo and other symptoms of patients with stage Ⅲ or Ⅳ Meniere's disease who had failure to conventional conservative treatment,and can preserve the residual hearing function in considerable extent.

Objective:To investigate the efficacy and safety of the Steward Scale(S Scale)and the Modified Aldrete Scale (A Scale) for resuscitation of children undergoing gastrointestinal endoscopy with general anesthesia.Methods:A total of 199 underage children who underwent non-intubated gastrointestinal endoscopy with general anesthesia in Children′s Hospital, Zhejiang University School of Medicine from July to December 2022 were retrospectively included in this study and divided into preschool group (36 cases), low school-age group (75 cases) and high school-age group (88 cases) according to age. S Scale and A Scale were also performed to evaluate the recovery from anesthesia. The vital signs of the children and the time required for reaching the target were recorded, and the scoring efficiency and safety of the two scales were compared.Results:The time required for S Scale to reach the standard (17.50 ± 9.29) min was significantly lower than that of A Scale (20.80 ± 12.61) min, and the difference between the two groups was statistically significant ( t = 2.97, P<0.01). In the low school-age group, oxygen saturation (0.989 ± 0.010) of A Scale was higher than that of S Scale (0.980 ± 0.015), the difference was significant ( t = 2.17, P<0.05). The time required for S Scale to reach the standard was negatively correlated with age ( r = -0.385, P<0.01). There was no significant correlation between the time required for A scale to reach the standard and the children′s age ( r = -0.089, P>0.05). Conclusions:Although Steward Scale is more efficient than modified Aldrete Scale in evaluating anesthesia resuscitation in underage children undergoing gastrointestinal endoscopy with general anesthesia, modified Aldrete Scale is safer than Steward Scale and is more conducive to ensuring the life safety of children.

Objective:To analyze the difference of clinical characteristics and outcomes of infants with moderate and severe pediatric acute respiratory distress syndrome(PARDS)diagnosed according to baseline oxygenation index(OI) in pediatric intensive care unit(PICU).Methods:Second analysis of the data collected from the "Efficacy of pulmonary surfactant (PS) in the treatment of children with moderate and severe ARDS" program.Retrospectively compare of the differences in clinical data such as general condition, underlying diseases, OI, mechanical ventilation, PS administration and outcomes among infants with moderate and severe PARDS divided by baseline OI who admitted to PICUs at 14 participating tertiary hospitals from 2016 to December 2021.Results:Among the 101 cases, 55 cases (54.5%) were moderate and 46 cases (45.5%) were severe PARDS.The proportion of male in the severe group (50.0% vs.72.7%, P=0.019) and the pediatric critical illness score(PCIS)[72 (68, 78) vs.76 (70, 80), P=0.019] were significantly lower than those in the moderate group, while there was no significant difference regarding age, body weight, etiology of PARDS and underlying diseases.The utilization rate of high-frequency ventilator in the severe group was significantly higher than that in the moderate group (34.8% vs.10.9%, P=0.004), but there was no significant difference in PS use, fluid load and pulmonary complications.The 24 h OI improvement (0.26±0.33 vs.0.04±0.34, P=0.001) and the 72 h OI improvement[0.34 (-0.04, 0.62) vs.0.15 (-0.14, 0.42), P=0.029)]in the severe group were significantly better than those in the moderate group, but there was no significant difference regarding mortality, length of hospital stay and intubation duration after diagnosis of PARDS between the two groups. Conclusion:In moderate and severe(divided by baseline OI) PARDS infants with invasive mechanical ventilation, children in severe group have better oxygenation improvement in the early stage after PARDS identified and are more likely to receive high frequency ventilation compared to those in moderate group.Baseline OI can not sensitively distinguish the outcomes and is not an ideal index for PARDS grading of this kind of patient.

BackgroundCompared with adult-onset schizophrenia， patients with adolescent-onset schizophrenia experience a high genetic susceptibility， severe negative symptoms， high recurrence rate， poor prognosis and social function recovery. And clarifying the brain functional alterations in adolescent-onset schizophrenia is of great significance for further elucidating the pathogenesis of the disease and exploring personalized and precise treatment. ObjectiveTo investigate the altered functional and effective connectivity of bilateral precuneus in first-episode patients with adolescent-onset schizophrenia based on resting-state functional magnetic resonance imaging （rs-fMRI）， thus providing reliable imaging evidence in guiding the study on mechanism involved in adolescent-onset schizophrenia. MethodsTwenty-one drugnaïve first-episode patients with adolescent-onset schizophrenia who met the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） criteria for schizophrenia were enrolled， and another 21 psychiatrially healthy controls matched on age， educational background and gender were concurrently selected. The schizophrenic subjects were evaluated using the Psychotic Symptom Rating Scales （PSYRATS） and Positive and Negative Symptom Scale （PANSS）. All participants underwent rs-fMRI scans， and the whole-brain seed-based functional and effective connectivity analyses were conducted in bilateral cuneus region. Then the correlation between functional connectivity strength and clinical symptoms of patients was discussed. ResultsIn terms of functional connectivity， the functional connectivity of bilateral precuneus and left middle temporal gyrus was increased in patient group compared with healthy control group ［P<0.01， family-wise error （FWE） correction at cluster level， P<0.05］. In terms of effective connectivity， patient group responded to negative feedback with greater activation of seed region and left middle frontal gyrus than healthy control group. Correlation analysis within patient group denoted that the decreased effective connectivity of bilateral precuneus and left middle frontal gyrus was positively correlated with the total PANSS score （r=0.450， P<0.05）. ConclusionThe resting-state functional and effective connectivity of bilateral precuneus is abnormally alerted in drugnaïve first-episode patients with adolescent-onset schizophrenia， and the decreased effective connectivity of bilateral precuneus and left middle frontal gyrus may be related to the development of clinical symptoms. ［Funded by National Key Research and Development Program of China （number， 2022YFC2009901， 2022YFC2009900）］

ObjectiveTo analyze the monitoring data of schistosomiasis from 2004 to 2021 in Suzhou New District， Jiangsu Province， and to provide evidence for improving schistosomiasis elimination strategies. MethodsFollowing the Opinions on Prevention and Control of Schistosomiasis， Parasitic Diseases and Endemic Diseases in Suzhou and the Technical Plan for Prevention and Control of Schistosomiasis， Parasitic Diseases and Endemic Diseases in Suzhou， the monitoring of schistosomiasis in the population and snail habitats from 2004 to 2021 was conducted. The Mann-Kendall method and Joinpoint regression method were employed to analyze the trend of epidemic indicators （such as seropositive rate， prevalence of snail frames， etc.）. Time series analysis （exponential smoothing model） was conducted to predict snail occurrence. ResultsFrom 2004 to 2021， a total of 73 680 people were serologically tested for schistosomiasis， with a positive rate of 0.084%. The seropositivity rate showed statistically significant differences between different years （χ²=70.73， P<0.05）， but there was no significant trend over time. In addition， 3 053 fecal tests were conducted and no positive result was found. The snail habitats covered an area of 70.11 hm² and showed a decreasing trend （Z=-1.97， P<0.05）. A total of 30 093 frames were surveyed， of which 19.038% contained snails. The difference in the prevalence of snail frames between different years was statistically significant （χ²=7 203.09， P<0.05）， with a decreasing trend in the prevalence of snail frames （Z=-2.05， P<0.05）. A total of 26 296 live snails were seized and density of live snails was 0.874 snails per frame， showing a decreasing trend in the density of live snails （Z=-2.35， P<0.05）. A total of 12 391 snails were dissected and no infected snail was found. The areas treated with molluscicides remained stable at 264.60 hm². An area of 27.77 hm² achieved the goal of snail eradication through environmental modification， with a decreasing trend （Z=-2.44， P<0.05）. It is estimated that the prevalence of snail frames and snail density will remain relatively stable from 2022 to 2026， but the snail habitat area will fluctuate significantly， showing an increasing trend. ConclusionNo indigenous cases of schistosomiasis and no infected snails are reported， indicating the successful consolidation of schistosomiasis prevention and control measures. However， the snail habitat area fluctuates greatly with an increasing trend， suggesting the need for long-term Oncomelania snail monitoring in local areas.

Objective:To investigate the molecular features of hand, foot and mouth disease (HFMD) caused by coxsackievirus A10 (CVA10) in Qingdao and analyze the clinical features of mild and severe cases.Methods:A total of 6 677 cases of HFMD routinely monitored by Qingdao Women and Children Hospital from 2014 to 2021 were enrolled. Throat swab samples were collected. Clinical data of these cases were retrospectively analyzed. Virus nucleic acid was extracted from the samples and the serotypes of enteroviruses were identified. The VP1 genes of CVA10 strains were amplified and sequenced. A phylogenetic tree based on the VP1 gene sequences was constructed using MEGA7. 0 software. SPSS23.0 software was used for statistical analysis.Results:There were 285 cases positive for CVA10, including 183 males and 102 females, and children under five years old accounted for 89.8%. Most of CVA10 infection occurred between the months of April to September. The count of white blood cells, the percentage of neutrophils, the concentration of hemoglobin, and the levels of aspartate aminotransferase and alanine transaminase were significantly higher in severe patients than in mild patients. Besides, chest radiography and brain CT revealed more abnormalities in severe patients, and the duration of ECG monitoring was longer in them. Compared with mild cases, severe cases developed rash early than fever with rash mostly on buttocks ( P<0.05). Phylogenetic analysis showed that most of the CVA10 strains circulating in Qingdao between 2014 and 2021 belonged to clade Ⅰ, and there were two variations A23V and I283V in the amino acid sequence of clade Ⅰ. Conclusions:This study showed that children of all ages were susceptible to CVA10, especially those under five years old. CVA10 showed complex and diverse epidemic trends in different regions and years.

Purpose: This study was performed to investigate the association of Glasgow prognostic score (GPS), combined positive score (CPS), and clinicopathological characteristics of locally advanced rectal cancer. Methods: Between February 2012 and February 2018, 103 patients with locally advanced rectal cancer treated by neoadjuvant chemoradiotherapy and total mesorectal excision (TME) were retrospectively evaluated. Results: According to the classification of the GPS, 85 (82.5%), 13 (12.6%), and 5 patients (4.9%) were classified as a score of 0, 1, and 2, respectively. Patients were classified into the GPS-low group (GPS of 0, n = 85) and GPS-high group (GPS of 1 or 2, n = 18) with an area under the curve of 0.582 for overall survival (OS). The mean programmed death-ligand 1 (PD-L1) CPS of the whole group was 2.24 (range, 0–70). The PD-L1 CPS of the GPS-high group was higher than the GPS-low group (P < 0.001). Multivariate analysis by Cox proportional hazards model indicated that GPS was associated with OS and diseasefree survival (DFS). Furthermore, PD-L1 CPS was associated with DFS (hazard ratio, 1.050; 95% confidence interval, 1.017– 1.083; P = 0.003). Conclusion Elevated GPS was related to the PD-L1 CPS. GPS and PD-L1 CPS were associated with the prognosis of locally advanced rectal cancer treated with neoadjuvant chemoradiotherapy followed by TME.

Senescence of activated hepatic stellate cells (aHSCs) is a stable growth arrest that is implicated in liver fibrosis regression. Senescent cells often accompanied by a multi-faceted senescence-associated secretory phenotype (SASP). But little is known about how alanine-serine-cysteine transporter type-2 (ASCT2), a high affinity glutamine transporter, affects HSC senescence and SASP during liver fibrosis. Here, we identified ASCT2 is mainly elevated in aHSCs and positively correlated with liver fibrosis in human and mouse fibrotic livers. We first discovered ASCT2 inhibition induced HSCs to senescence in vitro and in vivo. The proinflammatory SASP were restricted by ASCT2 inhibition at senescence initiation to prevent paracrine migration. Mechanically, ASCT2 was a direct target of glutaminolysis-dependent proinflammatory SASP, interfering IL-1α/NF-κB feedback loop via interacting with precursor IL-1α at Lys82. From a translational perspective, atractylenolide III is identified as ASCT2 inhibitor through directly bound to Asn230 of ASCT2. The presence of -OH group in atractylenolide III is suggested to be favorable for the inhibition of ASCT2. Importantly, atractylenolide III could be utilized to treat liver fibrosis mice. Taken together, ASCT2 controlled HSC senescence while modifying the proinflammatory SASP. Targeting ASCT2 by atractylenolide III could be a therapeutic candidate for liver fibrosis.
