Objective: To investigate the current status of benefit finding among young and middle-aged patients with type 2 diabetes mellitus (T2DM) and analyze its influencing factors, so as to provide a reference for improving the level of benefit finding in this population. Methods: From November 2022 to May 2023, young and middle-aged patients with T2DM aged 18-59 years hospitalized in the endocrinology departments of 2 tertiary hospitals in Hengyang City, Hunan Province were selected as survey subjects by a convenience sampling method. Basic demographic information was collected using a general questionnaire survey. Benefit finding, resourcefulness, and stigma were evaluated using the Benefit Finding Scale, the Chinese Version of the Resourcefulness Scale, and the Type 2 Diabetes Stigma Assessment Scale, respectively. A multiple linear regression model was used to analyze the influencing factors of benefit finding among young and middle-aged patients with T2DM. Results: A total of 305 young and middle-aged patients with T2DM were investigated, including 222 males (72.79%) and 83 females (27.21%). There were 231 cases aged 45-59 years, accounting for 75.74%. The scores for benefit finding, resourcefulness, and stigma were (42.86±6.06), (75.12±11.30), and (41.20±10.10), respectively. Multiple linear regression analysis showed that young and middle-aged patients with T2DM who were male (β′=0.088), aged 18-<45 years (β′=0.083), absence of diabetes complications (β′=0.124), and had higher resourcefulness scores (β′=0.679) had higher levels of benefit finding, while patients with higher stigma scores (β′=-0.097) had lower levels of benefit finding. Conclusion The level of benefit finding among young and middle-aged patients with T2DM was moderate, and was related to gender, age, diabetes complications, resourcefulness, and stigma.

Perineural invasion (PNI) by tumor cells is a key phenotype of highly-invasive oral squamous cell carcinoma (OSCC). Since Schwann cells (SCs) and fibroblasts maintain the physiological homeostasis of the peripheral nervous system, and we have focused on cancer-associated fibroblasts (CAFs) for decades, it's imperative to elucidate the impact of CAFs on SCs in PNI⁺ OSCCs. We describe a disease progression-driven shift of PNI^- towards PNI⁺ during the progression of early-stage OSCC (31%, n = 125) to late-stage OSCC (53%, n = 97), characterized by abundant CAFs and nerve demyelination. CAFs inhibited SC proliferation/migration and reduced neurotrophic factors and myelin in vitro, and this involved up-regulated ER stress and decreased MAPK signals. Moreover, CAFs also aggravated the paralysis of the hind limb and PNI in vivo. Unexpectedly, leukemia inhibitory factor (LIF) was exclusively expressed on CAFs and up-regulated in metastatic OSCC. The LIF inhibitor EC330 restored CAF-induced SC inactivation. Thus, OSCC-derived CAFs inactivate SCs to aggravate nerve injury and PNI development.

Objective:To report the results of national surveillance on the distribution and antimicrobial resistance profile of clinical Gram-negative bacteria isolates from bloodstream infections in China in 2022.Methods:The clinical isolates of Gram-negative bacteria from blood cultures in member hospitals of national bloodstream infection Bacterial Resistant Investigation Collaborative System（BRICS）were collected during January 2022 to December 2022. Antibiotic susceptibility tests were conducted by agar dilution or broth dilution methods recommended by Clinical and Laboratory Standards Institute（CLSI）. WHONET 5.6 and SPSS 25.0 software were used to analyze the data.Results:During the study period，9 035 strains of Gram-negative bacteria were collected from 51 hospitals，of which 7 895（87.4%）were Enterobacteriaceae and 1 140（12.6%）were non-fermenting bacteria. The top 5 bacterial species were Escherichia coli（ n=4 510，49.9%）， Klebsiella pneumoniae（ n=2 340，25.9%）， Pseudomonas aeruginosa（ n=534，5.9%）， Acinetobacter baumannii complex（ n=405，4.5%）and Enterobacter cloacae（ n=327，3.6%）. The ESBLs-producing rates in Escherichia coli， Klebsiella pneumoniae and Proteus spp. were 47.1%（2 095/4 452），21.0%（427/2 033）and 41.1%（58/141），respectively. The prevalence of carbapenem-resistant Escherichia coli（CREC）and carbapenem-resistant Klebsiella pneumoniae（CRKP）were 1.3%（58/4 510）and 13.1%（307/2 340）；62.1%（36/58）and 9.8%（30/307）of CREC and CRKP were resistant to ceftazidime/avibactam combination，respectively. The prevalence of carbapenem-resistant Acinetobacter baumannii（CRAB）complex was 59.5%（241/405），while less than 5% of Acinetobacter baumannii complex was resistant to tigecycline and polymyxin B. The prevalence of carbapenem-resistant Pseudomonas aeruginosa（CRPA）was 18.4%（98/534）. There were differences in the composition ratio of Gram-negative bacteria in bloodstream infections and the prevalence of main Gram-negative bacteria resistance among different regions，with statistically significant differences in the prevalence of CRKP and CRPA（ χ2=20.489 and 20.252， P<0.001）. The prevalence of CREC，CRKP，CRPA，CRAB，ESBLs-producing Escherichia coli and Klebsiella pneumoniae were higher in provinicial hospitals than those in municipal hospitals（ χ2=11.953，81.183，10.404，5.915，12.415 and 6.459， P<0.01 or <0.05），while the prevalence of CRPA was higher in economically developed regions（per capita GDP ≥ 92 059 Yuan）than that in economically less-developed regions（per capita GDP <92 059 Yuan）（ χ2=6.240， P=0.012）. Conclusions:The proportion of Gram-negative bacteria in bloodstream infections shows an increasing trend，and Escherichia coli is ranked in the top，while the trend of CRKP decreases continuously with time. Decreasing trends are noted in ESBLs-producing Escherichia coli and Klebsiella pneumoniae. Low prevalence of carbapenem resistance in Escherichia coli and high prevalence in CRAB complex have been observed. The composition ratio and antibacterial spectrum of bloodstream infections in different regions of China are slightly different，and the proportion of main drug resistant bacteria in provincial hospitals is higher than those in municipal hospitals.

Among them, the content validity quality of the Maternal-fetal Attachment Tool was sufficient (evidence quality was advanced), the structural validity quality was uncertain (evidence quality was intermediate), the internal consistency quality was sufficient (evidence quality was advanced) and the hypothesis testing quality was sufficient (evidence quality was advanced), which was recommended at level A.Conclusions:This study systematically evaluates seven measurement tools for maternal-infant attachment, among which the Maternal-fetal Attachment Tool is class A tool and is recommended for use.

Objective:To explore the relationship between white matter integrity and cognitive function in first-episode children and adolescents with schizophrenia by diffusion tensor imaging (DTI).Methods:Totally 84 children and adolescents with first-episode schizophrenia who were hospitalized in the Department of Child and Adolescent Psychiatry at the Second Affiliated Hospital of Xinxiang Medical University from September 2017 to June 2021 were selected as the study group, and 35 healthy children and adolescents matched with the study group were selected as the control group. Positive and negative symptom scale (PANSS) was used to assess the patient's mental symptoms. Diffusion tensor imaging (DTI) scans were performed, and the structural integrity of white matter fibers in the brain was measured by tract-based spatial statistics (TBSS), with the indicators including fractional anisotropy (FA). The Chinese version of measurement and treatment research to improve cognition in schizophrenia consensus cognitive battery (MCCB) and the Stroop color-word test were used to evaluate the cognitive function of all subjects. SPSS 26.0 software was used to analyse the data by analysis of variance, independent sample t-test, Mann Whitney U-test and Pearson correlation analysis. Results:(1)The FA values of the right superior longitudinal tract (MNI: x=49, y=-40, z=31) and the left corticospinal tract (MNI: x=-27, y=-22, z=-19) in the study group were higher than those in the control group(both P<0.05). The FA values of the bilateral cingulate gyrus (MNI: x=-7, y=25, z=14; x=20, y=-50, z=25) and the occipital part of the corpus callosum radiation line (MNI: x=-19, y=-50, z=21) in the study group were lower than those in the control group(both P<0.05).(2)The trail making test score of the study group was higher than that of the control group( t=4.344, P<0.01), and the scores of the symbol coding, Hopkins verbal learning test-revised( HVLT-R), brief visuospatial memory test-revised(BVMT-R), word fluency test, number span, maze, Stroop word, Stroop color and Stroop color words were lower than those in the control group( t=-13.041--3.204, all P<0.05). (3) The FA value of right cingulate gyrus (hippocampus) was negatively correlated with the number span ( r=-0.269, P=0.023).The FA value in occipital part of the corpus callosum radiation line was positively correlated with the symbol code ( r=0.237, P=0.047).The FA value of the left lower longitudinal bundle was negatively correlated with the Stroop color and maze ( r=-0.289, -0.275; P=0.010, 0.020).The FA value of the right inferior longitudinal fasciculus was negatively correlated with the score of maze ( r=-0.254, P=0.032). The FA value of occipital part of the corpus callosum radiation line was positively correlated with positive symptom score ( r=0.170, P=0.040). Conclusion:Cognitive dysfunction in children and adolescent with first-episode schizophrenia may be related to abnormal white matter integrity in the brain.

Objective:To evaluate the diagnostic efficacy and practicality of the Jaundice color card (JCard) as a screening tool for neonatal jaundice.Methods:Following the standards for reporting of diagnostic accuracy studies (STARD) statement, a multicenter prospective study was conducted in 9 hospitals in China from October 2019 to September 2021. A total of 845 newborns who were admitted to the hospital or outpatient department for liver function testing due to their own diseases. The inclusion criteria were a gestational age of ≥35 weeks, a birth weight of ≥2 000 g, and an age of ≤28 days. The neonate′s parents used the JCard to measure jaundice at the neonate′s cheek. Within 2 hours of the JCard measurement, transcutaneous bilirubin (TcB) was measured with a JH20-1B device and total serum bilirubin (TSB) was detected. The Pearson′s correlation analysis, Bland-Altman plots and the receiver operating characteristic (ROC) curve were used for statistic analysis.Results:Out of the 854 newborns, 445 were male and 409 were female; 46 were born at 35-36 weeks of gestational age and 808 were born at ≥37 weeks of gestational age. Additionally, 432 cases were aged 0-3 days, 236 cases were aged 4-7 days, and 186 cases were aged 8-28 days. The TSB level was (227.4±89.6) μmol/L, with a range of 23.7-717.0 μmol/L. The JCard level was (221.4±77.0) μmol/L and the TcB level was (252.5±76.0) μmol/L. Both the JCard and TcB values showed good correlation ( r=0.77 and 0.80, respectively) and agreements (96.0% (820/854) and 95.2% (813/854) of samples fell within the 95% limits of agreement, respectively) with TSB. The JCard value of 12 had a sensitivity of 0.93 and specificity of 0.75 for identifying a TSB ≥205.2?μmol/L, and a sensitivity of 1.00 and specificity of 0.35 for identifying a TSB ≥342.0?μmol/L. The TcB value of 205.2?μmol/L had a sensitivity of 0.97 and specificity of 0.60 for identifying TSB levels of 205.2 μmol/L, and a sensitivity of 1.00 and specificity of 0.26 for identifying TSB levels of 342.0 μmol/L. The areas under the ROC curve (AUC) of JCard for identifying TSB levels of 153.9, 205.2, 256.5, and 342.0 μmol/L were 0.96, 0.92, 0.83, and 0.83, respectively. The AUC of TcB were 0.94, 0.91, 0.86, and 0.87, respectively. There were both no significant differences between the AUC of JCard and TcB in identifying TSB levels of 153.9 and 205.2 μmol/L (both P>0.05). However, the AUC of JCard were both lower than those of TcB in identifying TSB levels of 256.5 and 342.0 μmol/L (both P<0.05). Conclusions:JCard can be used to classify different levels of bilirubin, but its diagnostic efficacy decreases with increasing bilirubin levels. When TSB level are ≤205.2 μmol/L, its diagnostic efficacy is equivalent to that of the JH20-1B. To prevent the misdiagnosis of severe jaundice, it is recommended that parents use a low JCard score, such as 12, to identify severe hyperbilirubinemia (TSB ≥342.0 μmol/L).

Objective To investigate the effect and mechanism of Nuanxinkang on plaque formation in obstructive sleep apnea-hypopnea syndrome(OSAHS)comorbid with atherosclerosis(AS)mice by inhibiting endothelial-to-mesenchymal transition(EndMT).Methods Male ApoE-/-mice were randomly divided into six groups:control group,model group,atorvastatin group(2.6 mg·kg-1)and Nuanxinkang low-,medium-and high-dose groups(crude drug 3.5,7.0,14.0 g·kg-1),with eight mice in each group.The mice were exposed to chronic intermittent hypoxia(CIH)environment during sleep for a long time,and fed with high-fat diet to replicate OSAHS comorbid with AS mouse model.Oil red O staining was used to observe the formation of plaque on aortic intima in mice.Masson trichrome staining was used to evaluate the collagen content of atherosclerotic plaques in the aortic root of mice.The expressions of endothelial cell marker CD31 and EndMT marker Vimentin in aortic plaque were detected by immunofluorescence.Blood lipid levels were determined by ELISA;the mRNA expression levels of EndMT markers α-SMA and Cdh2 in aortic tissue were detected by qPCR.Results Compared with the control group,the area of aortic atherosclerotic plaque in the model group was significantly increased(P＜0.01),and the area of collagen deposition in the aortic root plaque was significantly increased(P＜0.01).The number of CD31 positive cells in the plaque were significantly decreased(P＜0.01),and the number of Vimentin positive cells were significantly increased(P＜0.01).Serum TG,T-CHO and LDL-C levels were significantly increased(P＜0.01),and HDL-C level was significantly decreased(P＜0.01).The mRNA expression levels of α-SMA and Cdh2 in aortic tissue were significantly increased(P＜0.01).Compared with the model group,the area of aortic atherosclerotic plaque in Nuanxinkang groups were significantly reduced(P＜0.05,P＜0.01),and the collagen deposition area of aortic root atherosclerotic plaque were significantly reduced(P＜0.05,P＜0.01).The number of CD31 positive expression cells in the plaque of Nuanxinkang high-dose group were significantly increased(P＜0.05),and the number of Vimentin positive expression cells in the plaque of Nuanxinkang medium-and high-dose groups were significantly decreased(P＜0.05,P＜0.01).The serum TG level of mice in the high-dose group of Nuanxinkang was significantly decreased(P＜0.01).The serum T-CHO and LDL-C levels of mice in each Nuanxinkang administration group were significantly decreased(P＜0.05,P＜0.01).The serum HDL-C levels of mice in the medium-and high-dose groups of Nuanxinkang were significantly increased(P＜0.01).The mRNA expression levels of α-SMA and Cdh2 in aortic tissue of mice in each treatment group were significantly decreased(P＜0.01).Conclusion Nuanxinkang can effectively reduce the plaque formation in OSAHS comorbid with atherosclerosis mice,which may be related to its inhibition of EndMT and reduction of collagen fiber formation.

Objective:To report the results of national surveillance on the distribution and antimicrobial resistance profile of clinical Gram-positive bacteria isolates from bloodstream infections in China in 2022.Methods:The clinical isolates of Gram-positive bacteria from blood cultures in member hospitals of National Bloodstream Infection Bacterial Resistant Investigation Collaborative System（BRICS）were collected during January 2022 to December 2022. Antibiotic susceptibility tests were conducted by agar dilution or broth dilution methods recommended by Clinical and Laboratory Standards Institute（CLSI）. WHONET 5.6 and SPSS 25.0 software were used to analyze the data.Results:A total of 3 163 strains of Gram-positive pathogens were collected from 51 member units，and the top five bacteria were Staphylococcus aureus（ n=1 147，36.3%），coagulase-negative Staphylococci（ n=928，29.3%）， Enterococcus faecalis（ n=369，11.7%）， Enterococcus faecium（ n=296，9.4%）and alpha-hemolyticus Streptococci（ n=192，6.1%）. The detection rates of methicillin-resistant Staphylococcus aureus（MRSA）and methicillin-resistant coagulase-negative Staphylococci（MRCNS）were 26.4%（303/1 147）and 66.7%（619/928），respectively. No glycopeptide and daptomycin-resistant Staphylococci were detected. The sensitivity rates of Staphylococcus aureus to cefpirome，rifampin，compound sulfamethoxazole，linezolid，minocycline and tigecycline were all >95.0%. Enterococcus faecium was more prevalent than Enterococcus faecalis. The resistance rates of Enterococcus faecium to vancomycin and teicoplanin were both 0.5%（2/369），and no vancomycin-resistant Enterococcus faecium was detected. The detection rate of MRSA in southern China was significantly lower than that in other regions（ χ2=14.578， P=0.002），while the detection rate of MRCNS in northern China was significantly higher than that in other regions（ χ2=15.195， P=0.002）. The detection rates of MRSA and MRCNS in provincial hospitals were higher than those in municipal hospitals（ χ2=13.519 and 12.136， P<0.001）. The detection rates of MRSA and MRCNS in economically more advanced regions（per capita GDP≥92 059 Yuan in 2022）were higher than those in economically less advanced regions（per capita GDP<92 059 Yuan）（ χ2=9.969 and 7.606， P=0.002和0.006）. Conclusions:Among the Gram-positive pathogens causing bloodstream infections in China， Staphylococci is the most common while the MRSA incidence decreases continuously with time；the detection rate of Enterococcus faecium exceeds that of Enterococcus faecalis. The overall prevalence of vancomycin-resistant Enterococci is still at a low level. The composition ratio of Gram-positive pathogens and resistant profiles varies slightly across regions of China，with the prevalence of MRSA and MRCNS being more pronounced in provincial hospitals and areas with a per capita GDP≥92 059 yuan.
