Objective To explore the antimicrobial resistance of carbapenem-resistant Klebsiella pneumoniae(CRKP)isolated from blood and the related risk factors for infection in patients.Methods Clinical data of 383 KP-infected patients from whose blood Klebsiella pneumoniae(KP)were isolated during hospitalization period in a hos-pital from January 2018 to December 2021 were retrospectively analyzed.Patients were divided into CRKP group(n=114)and non-CRKP group(n=269)based on antimicrobial resistance.According to the prognosis,114 patients in the CRKP group were subdivided into the death group(n=30)and the survival group(n=84).General informa-tion,underlying diseases,antimicrobial use,and infection outcomes of two groups of patients were compared,and risk factors for infection and death after infection were analyzed.Results The resistance rates of KP to tigecycline and compound sulfamethoxazole showed upward trends,with statistically significant differences(both P=0.008).The CRKP group had higher resistance rates to amikacin,aztreonam,compound sulfamethoxazole,ciprofloxacin,cefepime,cefoperazone/sulbactam,piperacillin/tazobactam,tigecycline,ceftazidime,tobramycin,and levofloxacin,as well as higher in-hospital mortality than the non-CRKP group,with statistically significant differences(all P＜0.05).Acute pancreatitis prior to infection(OR=16.564,P＜0.001),hypoalbuminemia(OR=8.588,P＜0.001),stay in in-tensive care unit prior to infection(OR=2.733,P=0.017),blood transfusion(OR=3.968,P=0.001),broncho-scopy(OR=5.194,P=0.014),surgery within 30 days prior to infection(OR=2.603,P=0.010),and treatment with carbapenems(OR=2.663,P=0.011)were independent risk factors for the development of CRKP blood-stream infection(BSI).Cardiac insufficiency before infection(OR=11.094,P=0.001),combined with pulmonary infection(OR=20.801,P=0.010),septic shock(OR=9.783,P=0.002),disturbance of consciousness(OR=11.648,P=0.001),and receiving glucocorticoid treatment(OR=5.333,P=0.018)were independent risk factors for mortality in patients with CRKP BSI.Conclusion The resistance rate of KP from BSI to tigecycline and com-pound sulfamethoxazole presents upward trend.Underlying diseases,invasive procedures,and carbapenem treat-ment are closely related to CRKP BSI.Cardiac insufficiency,pulmonary infection,septic shock,disturbance of con-sciousness,and glucocorticoid treatment can lead to death of patients with CRKP BSI.

AIM: To investigate the correlation between the ocular demodex infection and the composition of meibum lipid flora.METHODS: A non-interventional and observational study was performed on recruited 39 patients in our hospital between July 2020 and February 2021. They were divided into control group(n=14), meibomian gland dysfunction(MGD)group(n=14), and demodex group(FM, n=11)according to the presence or absence of demodex infection or MGD. High-throughput sequencing of V3-V4 fragment of 16S rRNA gene was performed on the meibomian ester samples of the three groups of subjects, and bioinformatics analysis was performed on the sequencing data to study the composition and difference of meibum lipid flora in the subjects of ocular demodex.RESULTS: Pseudomonas and Comamonas in FM group were significantly higher than those in control group and MGD group(P<0.05), while Ralstonia in Demodex infection group was significantly lower than that in control group and MGD group(P<0.05). The microbial richness and community diversity of meibum lipid flora of the MGD group and the FM group were significantly higher than those of the control group(P<0.05).CONCLUSION: Ocular demodex infection changed the composition of meibum lipid flora and increased the microbial richness and community diversity of meibum lipid flora.

Blood stasis syndrome is one of the core clinical syndrome of rheumatoid arthritis (RA), but the biological connotation of this syndrome is not clear, and there is a lack of disease improved animal models that match the characteristics of this disease and syndrome. The aim of this study was to screen the candidate biomarker gene set of blood stasis syndrome of RA, reveal the biological connotation of this syndrome, and explore and evaluate the preparation method of the improved animal model based on the characteristics of "disease-syndrome-symptom". The study was approved by the ethics committee of Guang'anmen Hospital, Chinese Academy of Traditional Chinese Medicine (No. 2019-073-KY-01) and the First Affiliated Hospital of Tianjin University of Traditional Chinese Medicine (No. TYLL2021[K]018), and the study subjects gave their informed consent. Animal welfare and experimental procedures followed the regulations of the Experimental Animal Ethics Committee of the Chinese Academy of Traditional Chinese Medicine (No. IBTCMCACMS21-2207-01). The whole blood samples were collected clinically from RA patients with blood stasis syndrome (3 cases) or other syndromes (7 types, 3 cases/type), and healthy volunteers (4 cases), and then transcriptome sequencing, KEGG, gene set enrichment analysis (GSEA) and weighted correlation network analysis (WGCNA) analysis were performed. 126 pivotal genes were screened, and their functional annotation results were significantly enriched in "immune-inflammation" related pathways and lipid metabolism regulation (sphingolipids, ether lipid metabolism and steroid biosynthesis). Syndrome-symptom mapping of hub gene set to the TCM primary and secondary symptoms, Western phenotypic symptoms and pathological links showed that joint tingling, abnormal joint morphology, petechiae and abnormal blood circulation are representative of blood stasis syndrome of RA. The results of the improved animal model showed that the rats in the collagen-induced arthritis + adrenaline hydrochloride (CIA+Adr) 3 model group had increased blood rheology, coagulation, platelet function and endothelial function abnormalities compared with the CIA-alone model group, suggesting that the rats with blood stasis syndrome of RA may be in a state of "blood stasis". The results of the study can help to advance the objective study of the evidence of blood stasis syndrome in RA, and provide new ideas for the establishment of an animal model that reflects the clinical characteristics of the disease and syndrome.

Objective:To analysis the prevalence and characteristics of comorbid insomnia and sleep disordered breathing (SDB) in community population.Methods:This is a cross-sectional study. Cluster sampling was applied. Community residents in Shantou and Meizhou were investigated during April to May, 2021. Essential information collection, sleep related health investigation, and sleep study were conducted. Insomnia was defined as the insomnia severity index (ISI)≥8. A type Ⅳ wearable intelligent sleep monitor was applied for sleep study. Comorbid insomnia and SDB was defined as both diagnosis of insomnia and SDB. Statistical analysis was conducted by SPSS 25. Prevalence and characteristics of insomnia only, SDB only and comorbid insomnia and SDB were analyzed. Logistic regression was conducted to analyze the relationship between sleep disorders and unrestored sleep, abnormal glucose metabolism, hyperlipidemia, and cardiovascular disease.Results:There were 3 730 residents completed the investigation. The median age was 55.0 (46.0, 63.0) years. The prevalence of insomnia only, SDB only, and comorbid insomnia and SDB were 26.0%, 20.2%, and 10.4% respectively. The incidence of unrestored sleep in insomnia only and comorbid insomnia and SDB were 2.900 times and 3.777 times of that in no insomnia or SDB (both P<0.001); the risk of hyperlipidemia was elevated in insomnia only, SDB only and comorbid insomnia and SDB ( OR=1.553, 1.415, and 1.868; all P<0.05); the risk of cardiovascular disease increased 40.8% in SDB only ( P=0.001), and 42.1% in comorbid insomnia and SDB ( P=0.007), after adjusted by age, sex, body mass index (BMI), smoking, drinking, abnormal glucose metabolism, and hyperlipidemia. Stratified analysis revealed that young female (age<60 years) with normal BMI (<25 kg/m 2) and comorbid insomnia and SDB were associated with higher risk of cardiovascular disease. Female with normal body weight and insomnia only or comorbid insomnia and SDB were associated with higher risk of hyperlipidemia. Conclusions:The prevalence of comorbid insomnia and SDB is high in community population. Patients with comorbid insomnia and SDB present with more significant unrestored sleep, and are correlated with higher risk of hyperlipidemia and cardiovascular diseases.

Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ²=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

Objective:To explore the effect of acknowledge, introduction, duration, explain and thank (AIDET) communication model on the awareness rate of health knowledge, self-perceived burden and quality of life of stroke patients in return visits.Methods:Using the convenient sampling method, a total of 300 stroke patients who were admitted to the First Affiliated Hospital of Zhengzhou University from January 2017 to December 2019 were selected as the research objects. According to the odd and even order of admission, they were divided into the observation group and the control group, with 150 cases in each group. The control group was given regular communication mode intervention, while the observation group was given AIDET communication model intervention. Hamilton Anxiety Scale (HAMA) , Hamilton Depression Scale (HAMD) , awareness rate of health knowledge, Self-Perceived Burden Scale (SPBS) score, the MOS Item Short From Health Survey (SF-36) score and nursing satisfaction were compared between two groups.Results:After intervention, HAMA and HAMD scores in the observation group were lower than those in the control group, and the differences were statistically significant ( P<0.05) . After the intervention, the awareness rate of health knowledge in the observation group was 96.67% (145/150) , which was higher than 83.33% (125/150) in the control group, and the difference was statistically significant ( P<0.05) . After the intervention, the total score of SPBS of the observation group was lower than that of the control group, and the difference was statistically significant ( P<0.05) . There was no statistically significant difference in the economic burden between the two groups ( P>0.05) . After the intervention, the SF-36 score in all dimensions and nursing satisfaction of the observation group were higher than those of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:AIDET communication mode can reduce the negative emotion and self-feeling burden of stroke patients in return visits and improve their awareness rate of health knowledge and nursing satisfaction.

Objective:To investigate the status quo of psychological characteristics of mindfulness, family concern and rehabilitation compliance of patients undergoing hip arthroplasty and to explore the internal relationships between psychological characteristics of mindfulness, family concern and rehabilitation compliance of patients undergoing hip arthroplasty in order to clarify the mediating effect of psychological characteristics of mindfulness.Methods:Using the convenient sampling method, a total of 101 patients who underwent hip arthroplasty in Department of Orthopedics in Peking University Shenzhen Hospital from July 2017 to June 2018 were selected as research objects. Five Facet Mindfulness Questionnaire (FFMQ) , Family Adaptability, Partnership, Growth, Affection, and Resolve (Family APGAR) Index and Rehabilitation Compliance Scale were used to conduct questionnaire surveys. The Pearson correlation analysis were used to analyze the correlations between rehabilitation compliance, family concern and psychological characteristics of mindfulness. Then a hypothetical model was established to analyze the mediating effect of psychological characteristics of mindfulness between family concern and rehabilitation compliance.Results:Finally, 90 valid questionnaires were collected. The total scores of FFMQ, Family APGAR Index and Rehabilitation Compliance Scale were respectively (115.01±8.99) , (7.27±0.84) and (5.27±0.92) . The psychological characteristics of mindfulness, family concern and rehabilitation compliance of patients with hip replacement were positively correlated ( r=0.562, 0.491; P<0.01) . The constructed mediation model showed that family concern had a positive predictive effect on rehabilitation compliance ( P<0.05) , psychological characteristics of mindfulness had a positive predictive effect on rehabilitation compliance ( P<0.05) , and psychological characteristics of mindfulness played a mediating role between family concern and rehabilitation compliance of patients with hip replacement. Conclusions:In this study, family concern, psychological characteristics of mindfulness and rehabilitation compliance of patients with hip replacement are all at a moderate level. Psychological characteristics of mindfulness of patients, family concern and postoperative rehabilitation compliance are positively correlated, and psychological characteristics of mindfulness has a mediating role between family concern and rehabilitation compliance. Medical staff can carry out mindfulness psychological interventions for patients with hip replacement to improve family concern and promote rehabilitation compliance of patients.

OBJECTIVE: To evaluate the efficacy and safety of Tongxiening Granules (, TXNG) in the treatment of irritable bowel syndrome with predominant diarrhea (IBS-D). METHODS: A randomized, double-blind, double-dummy, and positive parallel controlled clinical trial was conducted from October 2014 to March 2016. Totally 342 patients from 13 clinical centers were enrolled and randomly assigned (at the ratio of 1:1) to a treatment group (171 cases) and a control group (171 cases) by a random coding table. The patients in the treatment group were administered orally with TXNG (5 g per time) combined with pinaverium bromide Tablet simulator (50 mg per time), 3 times per day. The patients in the control group were given TXNG simulator (5 g per time) combined with pinaverium bromide Tablets (50 mg per time), 3 times per day. The treatment course lasted for 6 weeks. The improvement of Irritable Bowel Syndrome Symptom Severity Score (IBS-SSS) was used to evaluate the primary outcome. Secondary outcomes included adequate relief (AR) rate, Irritable Bowel Syndrome-Quality of Life Questionnaire (IBS-QOL), Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), and the recurrence rate at follow-ups. Safety indices including the adverse events (AEs) and related laboratory tests were evaluated. RESULTS: Primary outcome: IBS-SSS at baseline, weeks 2, 4, 6 showed no statistical significance in both full analysis set (FAS) and per protocol set (PPS, P>0.05). After 6 weeks of treatment, the total effective rate of IBS-SSS scores in the treatment group (147/171,86.0%) was higher than the control group (143/171, 83.6%) by FAS (P>0.05). In regard to secondary outcomes, after 6-week treatment, there was no significant difference in AR rate, total score of IBS-QOL, improvement of HAMD and HAMA total scores between the two groups (P>0.05). The recurrence rate at 8-week follow-up was 12.35% (10/18) in treatment group and 15.79% (12/76) in control group, respectively (P>0.05). A total of 21 AEs occurred in 15 cases, of which 11 occurred in 8 cases in the treatment group and 10 AEs in 7 cases in the control group. The incidence of AEs had no statistical significance between the two goups (P>0.05). CONCLUSION Tongxiening Granules could relieve the symptoms of patients with IBS-D and the treatment effect was comparable to pinaverium bromide. (No. ChiCTR-IPR-15006415).
