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.

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.

Aural vertigo frequently encountered in the otolaryngology department of traditional Chinese medicine （TCM） mainly involves peripheral vestibular diseases of Western medicine， such as Meniere's disease， benign paroxysmal positional vertigo， vestibular neuritis， and vestibular migraine， being a hot research topic in both TCM and Western medicine. Western medical therapies alone have unsatisfactory effects on recurrent aural vertigo， aural vertigo affecting the quality of life， aural vertigo not relieved after surgery， aural vertigo with complex causes， and children's aural vertigo. The literature records and clinical practice have proven that TCM demonstrates unique advantages in the treatment of aural vertigo. The China Association of Chinese medicine sponsored the "17th youth salon on the diseases responding specifically to TCM： Aural vertigo" and invited vertigo experts of TCM and Western medicine to discuss the difficulties and advantages of TCM diagnosis and treatment of aural vertigo. The experts deeply discussed the achievements and contributions of TCM and Western medicine in the diagnosis and treatment of aural vertigo， the control and mitigation of the symptoms， and the solutions to disease recurrence. The discussion clarified the positioning and advantages of TCM treatment and provided guidance for clinical and basic research on aural vertigo.

Objective To assess the tear film stability and morphological characteristics of the tarsal gland in myopic children.Methods In this prospective descriptive study,myopic children who performed refractive examinations in the Pediatric Ophthalmology & Refraction Clinic,Jinan Mingshui Eye Hospital from November 2021 to November 2022 were in-cluded.An Ocular Surface Disease Index(OSDI)questionnaire survey was carried out;tear meniscus height(TMH),non-invasive first breakup time(NIf-BUT)and images of the tarsal glands were obtained by OCULUS Keratograph 5M compre-hensive ocular surface analyzer.In addition,the atrophy and tortuosity of tarsal glands were scored to analyze the tear film stability and clinical characteristics of tarsal glands in myopic children.Results A total of 48 myopic children(91 eyes)aged from 7 to 16(10.25±2.23)years were recruited,including 27 males(56.25％)and 21 females(43.75％).The aver-age TMH was(0.19±0.04)mm(95％CI:0.18-0.19)and the average NIf-BUT was(5.40±2.62)s(95％CI:4.90-5.94);the TMH was positively correlated with NIf-BUT(r=0.223,P=0.034).The tarsal gland atrophy score was 1(0,1).The tortuosity score of the upper and lower tarsal gland was 0(0,1)and 0(0,0),respectively,with a statistically significant difference(Z=3.692,P＜0.001).In all subjects,49 eyes(53.85％)had tarsal gland atrophy,and 37 eyes(40.66％)had tarsal gland tortuosity.There were significant differences in TMH and NIf-BUT between children aged＜12 years and children aged ≥12 years(both P＜0.05).There was a significant difference in TMH between children with an OSDI score＜13 and children with an OSDI score ≥ 13(t=2.305,P=0.026).There was a significant difference in NIf-BUT between mild and moderate myopia children(t=2.300,P=0.024);the spherical equivalent was positively correlated with NIf-BUT(r=0.283,P=0.023).Conclusion Children with mild to moderate myopia show low tear film stability and a certain proportion of abnormal morphology in tarsal glands.In addition to the refractive status of children,attention should also be paid to ocular surface health in the refraction clinic.

Objective　To explore the characteristics of toxic heavy metal pollution in atmospheric PM2.5 (Particulate matter 2.5) during winter in Nanning City and to evaluate the health risks for the population. Methods　Atmospheric PM2.5 samples were continuously collected in the urban areas of Nanning from January to February 2019. The concentrations of seven toxic heavy metals, including cadmium (Cd), arsenic (As), chromium (Cr), lead (Pb), nickel (Ni), mercury (Hg), and manganese (Mn) in atmospheric PM2.5 were analyzed by X-ray fluorescence spectrometry. The pollution characteristics of toxic heavy metals were studied by geo-accumulation index and enrichment factor methods, and their health risks to children and adults were assessed using the health risk assessment model of the United States Environmental Protection Agency. Results　The mass concentration of atmospheric PM2.5 in Nanning in winter 2019 was (44±29) μg/m3, which was generally at a low level. Different degrees of pollution were found for Hg, Cd, As, Cr, and Pb in PM2.5, with Hg and Cd being more seriously polluted. Hg and Cd were highly enriched in PM2.5, followed by Pb with moderate enrichment. These three elements mainly originated from man-made pollution. As, Cr and Ni were mildly enriched and affected by both natural and anthropogenic sources. The non-carcinogenic risks were in the order of As>Pb>Hg>Cr>Cd>Mn>Ni. The total non-carcinogenic risks for the three populations were all less than 1, which is within acceptable limits. The carcinogenic risks were ranked as Cr>As>Cd>Ni, with Cr, As, and Cd posing carcinogenic risks to children and adults ranging from 1×10-6 to 1×10-4. Moreover, the total carcinogenic risks of heavy metals (Cr, As, Cd, and Ni) were higher than 1×10-4 for children, indicating a potential carcinogenic risk. Conclusions　The mass concentration of PM2.5 and heavy metal elements in Nanning City during the winter of 2019 was relatively low, but the pollution of heavy metals still exists. The non-carcinogenic risk of heavy metals is within an acceptable range, but the carcinogenic risk poses a potential danger to children.

Rheumatoid arthritis （RA） is a refractory autoimmune disease that can cause symmetrical polyarticular disease. The key mechanism of its occurrence and development is the dysequilibrium of helper T cell 17 （Th17）/regulatory T cell （Treg） balance. Therefore， reconstructing Th17/Treg balance may be a new strategy for the treatment of RA. Traditional Chinese medicine has significant advantages in the treatment of RA such as integrity， multi-target， multi-link and multi-path. This paper summarizes the basic and clinical studies on the regulation of Th17/Treg balance in the treatment of RA by traditional Chinese medicine in the past five years， and finds that the active components/sites of traditional Chinese medicine such as flavonoids， alkaloids and terpenes have unique advantages in the regulation of Th17/Treg balance. The traditional Chinese medicine compound formula interferes with Th17/Treg balance by exerting the effects of dispelling wind， dehumidifying， removing blood stasis， unblocking collaterals， relieving pain， dispersing cold and strengthening health. The effect of external treatment of traditional Chinese medicine is obvious and can be used as a clinical adjuvant therapy for RA； related mechanisms of action include regulating the production of inflammatory factors， regulating the expression of transcription factors and interfering with the activation of signaling pathways. However， the existing research has the shortcomings of insufficient mechanism research， few clinical research， limited external treatment research of traditional Chinese medicine， and lack of combination therapy research， which need to be improved by follow- up research.

Objective:To explore the safety and effectiveness of the application of sevoflurane inhalation sedation and analgesia during dressing changes in children with extensive burns.Methods:A prospective randomized controlled research was conducted. From March 2020 to January 2023, 216 children with extensive burns who met the inclusion criteria were admitted to the Department of Burns and Plastic Surgery of Kunming Children's Hospital. According to the random number table, the children were divided into sevoflurane group and ibuprofen group, with 103 cases left in sevoflurane group (67 males and 36 females, aged 1 (1, 2) years), and 98 cases left in ibuprofen group (67 males and 31 females, aged 1 (1, 2) years) after the exclusion of several dropped-out children. Children in sevoflurane group received sevoflurane inhalation for sedation and analgesia during dressing changes, while those in ibuprofen group took oral ibuprofen for analgesia before dressing changes. The heart rate, mean arterial pressure (MAP), and percutaneous arterial oxygen saturation (SpO 2) of the children were monitored and recorded at 30 minutes before the start of dressing changes, immediately after debridement, and at 30 minutes after the completion of dressing changes. The face, legs, activity, cry, and consolability scale and Ramsay sedation scale were used to evaluate the pain intensity and degree of sedation, respectively, at 30 minutes before the start of dressing changes, immediately after debridement, and at 30 minutes after the completion of dressing changes. The duration of dressing changes and the total number of dressing changes during hospitalization were recorded. The Houston Pain Outcome Instrument questionnaire was used to assess the satisfaction of the dressing-changing surgeons and a family member of the child with the analgesic effects during the process of dressing change when the children were discharged from the hospital. The occurrence of adverse reactions such as respiratory depression and hypoxemia that occurred during the process of dressing change were monitored and recorded. Data were statistically analyzed with independent sample t test, analysis of variance for repeated measurement, Wilcoxon rank-sum test, chi-square test, and Fisher's exact probability test. Results:At 30 minutes before the start of dressing changes and 30 minutes after the completion of dressing changes, there were no statistically significant differences in heart rate, MAP, and SpO 2 between children in the two groups ( P>0.05). Immediately after debridement, compared with those in ibuprofen group, the heart rate and MAP of children in sevoflurane group were significantly decreased (with t values of 8.10 and 4.37, respectively, P<0.05), while the SpO 2 was significantly increased ( t=21.77, P<0.05). At 30 minutes before the start of dressing changes and 30 minutes after the completion of dressing changes, there were no statistically significant differences in the score of pain intensity and score of sedation degree between children in the two groups ( P>0.05). Immediately after debridement, compared with that in ibuprofen group, the score of pain intensity of children in sevoflurane group was significantly decreased, while the score of sedation degree was significantly increased (with t values of 42.87 and 72.45, respectively, P<0.05). The duration of dressing changes and the total number of dressing changes during hospitalization of patients in sevoflurane group were (18±3) min and (4.1±1.0) times, respectively, which were both significantly shorter than (26±7) min and less than (6.6±1.4) times in ibuprofen group, respectively (with t values of -4.44 and 14.17, respectively, P<0.05). Upon discharge, the satisfaction scores of dressing-changing surgeons and the family members of children with the analgesic effects during the process of dressing change in sevoflurane group were significantly higher than those in ibuprofen group (with t values of 44.23 and 36.55, respectively, P<0.05). There were no statistically significant differences in the incidence of respiratory depression, hypoxemia, hypotension, coughing, nausea, and vomiting during the process of dressing change between children in the two groups ( P>0.05). Conclusions:Application of sevoflurane inhalation during dressing changes in children with extensive burns can safely and effectively control pain and sedation, shorten the time for dressing change, with fewer adverse reactions. This method can be used for routine dressing change in pediatric burn wards.

BackgroundDepression presents a significant risk to the physical and mental health of the elderly. The relationship between sleep and depressive symptoms has become a major research focus. However， previous research findings on this relationship have yielded inconsistent conclusions. ObjectiveTo explore the relationship between sleep duration and depressive symptoms in the elderly， in order to provide insights into the prevention of depressive symptoms and delaying their progression in the elderly. MethodsData analysis involved 8 210 adults aged 60 years or older， utilizing data from the 2018 China Health and Retirement Longitudinal Study （CHARLS） survey. Participants were categorized into two groups those with depressive symptoms and those without- based on the Center for Epidemiologic Studies Depression-10 Scale （CESD-10） criteria. Logistic regression and restricted cubic spline models were used to analyze the association between sleep duration and depressive symptoms. ResultsThe 318 people with depressive symptoms were detected among the 8 210 elderly participants， with an average sleep duration of （6.14±2.05） hours per night. Restricted cubic spline models showed a non-linear association between sleep duration and depressive symptoms （χ²=412.670，P<0.01）. After adjusting for confounding factors， compared to the elderly with a sleep duration 7~7.9 hours， the risk of depressive symptoms in the elderly was 2.971 times higher （95% CI： 2.560~3.449， P<0.01） in those with a sleep duration <6 hours， 1.372 times higher （95% CI： 1.161~1.621， P<0.01） in those with 6~6.9 hours， and 1 185 times higher （95% CI： 1.009~1.393， P<0.05） in those with ≥8 hours. Subgroup analysis showed no correlation between sleep duration ≥8 hours and the risk of depressive symptoms across genders and the 60~69 age group （P>0.05）. ConclusionThere was an approximately nonlinear association between sleep duration and depressive symptoms， with differences by gender and age.［Funded by Sichuan Applied Psychology Research Center， Chengdu Medical College （number， CSXL-22226）］

Objective To explore the temporal and spatial distribution characteristics of air pollutants PM_2.5, PM₁₀, SO₂, CO, and NO₂, and their effects on acute cerebrovascular diseases in Jining City. Methods The data of patients with acute cerebrovascular disease treated in a 3A hospital in Jining from October 1, 2017, to November 31, 2019, were retrospectively collected. Combined with the air pollution data of 29 air quality monitoring stations in Jining City, the Kriging interpolation model was used to analyze the overall situation of air pollution in Jining. On this basis, the relationship between air pollution and acute cerebrovascular diseases in Jining City was analyzed. Results In Jining City, the incidence of acute cerebrovascular disease in male was higher than that in female, and the incidence in rural areas was significantly higher than that in urban areas. The spatial distribution showed a trend of gradual accumulation from southeast to northwest. The daily average concentrations of PM2.5 and PM10 were higher in winter and spring than in summer and autumn. The results of Kriging interpolation analysis showed that the concentrations of these air pollutants formed aggregation points in varying degrees. The spatial distribution of acute cerebrovascular disease patients in Jining City was highly consistent with the spatial distribution of air pollutant concentrations. Spearman correlation analysis showed that CO, SO₂, and NO₂ were positively correlated with the incidence of acute cerebrovascular disease, while the correlation between PM_2.5 and PM₁₀ and the incidence of acute cerebrovascular disease was not significant. Conclusion Some air pollutants such as CO, SO₂, and NO₂ have a positive correlation with the incidence of acute cerebrovascular disease, and the prevalence has a certain population and regional distribution. In the future work of cerebrovascular disease prevention, personal protection should be done according to local conditions and living environment of specific people.
