Objective: To analyze the prevalence and the risk factors of fungal sepsis in 25 neonatal intensive care units (NICU) among preterm infants in China, and to provide a basis for preventive strategies of fungal sepsis. Methods: This was a second-analysis of the data from the "reduction of infection in neonatal intensive care units using the evidence-based practice for improving quality" study. The current status of fungal sepsis of the 24 731 preterm infants with the gestational age of <34+0 weeks, who were admitted to 25 participating NICU within 7 days of birth between May 2015 and April 2018 were retrospectively analyzed. These preterm infants were divided into the fungal sepsis group and the without fungal sepsis group according to whether they developed fungal sepsis to analyze the incidences and the microbiology of fungal sepsis. Chi-square test was used to compare the incidences of fungal sepsis in preterm infants with different gestational ages and birth weights and in different NICU. Multivariate Logistic regression analysis was used to study the outcomes of preterm infants with fungal sepsis, which were further compared with those of preterm infants without fungal sepsis. The 144 preterm infants in the fungal sepsis group were matched with 288 preterm infants in the non-fungal sepsis group by propensity score-matched method. Univariate and multivariate Logistic regression analysis were used to analyze the risk factors of fungal sepsis. Results: In all, 166 (0.7%) of the 24 731 preterm infants developed fungal sepsis, with the gestational age of (29.7±2.0) weeks and the birth weight of (1 300±293) g. The incidence of fungal sepsis increased with decreasing gestational age and birth weight (both P<0.001). The preterm infants with gestational age of <32 weeks accounted for 87.3% (145/166). The incidence of fungal sepsis was 1.0% (117/11 438) in very preterm infants and 2.0% (28/1 401) in extremely preterm infants, and was 1.3% (103/8 060) in very low birth weight infants and 1.7% (21/1 211) in extremely low birth weight infants, respectively. There was no fungal sepsis in 3 NICU, and the incidences in the other 22 NICU ranged from 0.7% (10/1 397) to 2.9% (21/724), with significant statistical difference (P<0.001). The pathogens were mainly Candida (150/166, 90.4%), including 59 cases of Candida albicans and 91 cases of non-Candida albicans, of which Candida parapsilosis was the most common (41 cases). Fungal sepsis was independently associated with increased risk of moderate to severe bronchopulmonary dysplasia (BPD) (adjusted OR 1.52, 95%CI 1.04-2.22, P=0.030) and severe retinopathy of prematurity (ROP) (adjusted OR 2.55, 95%CI 1.12-5.80, P=0.025). Previous broad spectrum antibiotics exposure (adjusted OR=2.50, 95%CI 1.50-4.17, P<0.001), prolonged use of central line (adjusted OR=1.05, 95%CI 1.03-1.08, P<0.001) and previous total parenteral nutrition (TPN) duration (adjusted OR=1.04, 95%CI 1.02-1.06, P<0.001) were all independently associated with increasing risk of fungal sepsis. Conclusions: Candida albicans and Candida parapsilosis are the main pathogens of fungal sepsis among preterm infants in Chinese NICU. Preterm infants with fungal sepsis are at increased risk of moderate to severe BPD and severe ROP. Previous broad spectrum antibiotics exposure, prolonged use of central line and prolonged duration of TPN will increase the risk of fungal sepsis. Ongoing initiatives are needed to reduce fungal sepsis based on these risk factors.

Résumé
Cancer-related fatigue (CRF) belongs to the category of "consumptive disease" in TCM, and its occurrence is based on "internal deficiency" of the body causing by the tumor. Its nature is intermingled deficiency and excess. Its pathogenesis is the deficiency of qi, blood, yin and yang and zang-fu viscera dysfunction caused by disorders of "rise and fall of middle qi" and kidney origin depletion. The theory of "treating overstrain syndrome with warming methods" originates from Huang Di Nei Jing, which proposes that warming methods are the basic methods of treating consumptive disease. Therefore, starting from the cause and pathogenesis of CRF, this article sorted out the theoretical origin of "treating overstrain syndrome with warming methods", and discussed the clinical application of warming methods for the treatment of CRF combining with modern clinical research, with the purpose to provide references for clinical practice.
Résumé
UiO-66 (University of Oslo 66) is a kind of promising material that can improve the release and bioavailability of poorly water-soluble bioactive compounds of traditional Chinese medicine. However, the loading of quercetin in raw UiO-66 was not ideal. In this study, UiO-66-BH (UiO-66-blend-heating) was obtained by heating UiO-66 and KOH solution following blended them. UiO-66-BH maintained the outline of octahedral structure of UiO-66 but with obvious rough and uneven pores on the surface. UiO-66-BH had good adsorption of quercetin with saturation adsorption was 138.92 mg·g-1, the adsorption process belonged to single molecular layer adsorption and was controlled by chemisorption. UiO-66-BH can control the release of quercetin in simulated gastrointestinal fluid, and the drug concentration was significantly higher than that of free quercetin after long-term release (36% vs 9%). Compared with quercetin, the ABTS (2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) ammonium salt) radical scavenging activity of UiO-66-BH@quercetin drug delivery system decreased, while the DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity remained almost unchanged. The drug delivery system showed a strong antioxidant effect similar to quercetin. The findings indicated that UiO-66-BH could control release of quercetin and was expected to be used as a drug carrier material for some insoluble active components of traditional Chinese medicine such as quercetin.
Résumé
Objective: To describe the current status and trends in the treatment of patent ductus arteriosus (PDA) among very preterm infants (VPI) admitted to the neonatal intensive care units (NICU) of the Chinese Neonatal Network (CHNN) from 2019 to 2021, and to compare the differences in PDA treatment among these units. Methods: This was a cross-sectional study based on the CHNN VPI cohort, all of 22 525 VPI (gestational age<32 weeks) admitted to 79 tertiary NICU within 3 days of age from 2019 to 2021 were included. The overall PDA treatment rates were calculated, as well as the rates of infants with different gestational ages (≤26, 27-28, 29-31 weeks), and pharmacological and surgical treatments were described. PDA was defined as those diagnosed by echocardiography during hospitalization. The PDA treatment rate was defined as the number of VPI who had received medication treatment and (or) surgical ligation of PDA divided by the number of all VPI. Logistic regression was used to investigate the changes in PDA treatment rates over the 3 years and the differences between gestational age groups. A multivariate Logistic regression model was constructed to compute the standardized ratio (SR) of PDA treatment across different units, to compare the rates after adjusting for population characteristics. Results: A total of 22 525 VPI were included in the study, with a gestational age of 30.0 (28.6, 31.0) weeks and birth weight of 1 310 (1 100, 1 540) g; 56.0% (12 615) of them were male. PDA was diagnosed by echocardiography in 49.7% (11 186/22 525) of all VPI, and the overall PDA treatment rate was 16.8% (3 795/22 525). Of 3 762 VPI who received medication treatment, the main first-line medication used was ibuprofen (93.4% (3 515/3 762)) and the postnatal day of first medication treatment was 6 (4, 10) days of age; 59.3% (2 231/3 762) of the VPI had been weaned from invasive respiratory support during the first medication treatment, and 82.2% (3 092/3 762) of the infants received only one course of medication treatment. A total of 143 VPI underwent surgery, which was conducted on 32 (22, 46) days of age. Over the 3 years from 2019 to 2021, there was no significant change in the PDA treatment rate in these VPI (P=0.650). The PDA treatment rate decreased with increasing gestational age (P<0.001). The PDA treatment rates for VPI with gestational age ≤26, 27-28, and 29-31 weeks were 39.6% (688/1 737), 25.9% (1 319/5 098), and 11.4% (1 788/15 690), respectively. There were 61 units having a total number of VPI≥100 cases, and their rates of PDA treatment were 0 (0/116)-47.4% (376/793). After adjusting for population characteristics, the range of standardized ratios for PDA treatment in the 61 units was 0 (95%CI 0-0.3) to 3.4 (95%CI 3.1-3.8). Conclusions: From 2019 to 2021, compared to the peers in developed countries, VPI in CHNN NICU had a different PDA treatment rate; specifically, the VPI with small birth gestational age had a lower treatment rate, while the VPI with large birth gestational age had a higher rate. There are significant differences in PDA treatment rates among different units.

Objective: To evaluate the efficacy within the first 24 h post extracorporeal membrane pulmonary oxygenation (ECMO) and the impact of early efficacy on the prognosis of adult patients with fulminant myocarditis (FM). Methods: This retrospective case analysis study included hospitalized patients (age≥18 years) who were diagnosed with fulminant myocarditis from November 2016 to May 2021 in the First Affiliated Hospital of Zhengzhou University. Patients were divided into survival or non-survival groups according to treatment outcomes. The age, sex, treatments, drug use, ECMO use, clinical and laboratory data (before and 24 h after the use of ECMO) were analyzed. The change rate of clinical and laboratory data after 24 h use of ECMO was calculated to find differences between two groups. Multivariate logistic regression was used to analyze the related factors with in-hospital death and complication between the two groups. Results: A total of 38 FM patients treated with ECMO were included. There were 23 cases (60.5%) in the survival group, aged (39.6±13.7) years, and 17 (73.9%) cases were female. The total ECMO time was (134.4±71.3)h. There were 15 cases (39.5%) in non-survival group, aged (40.0±15.8) years, and there were 12(80.0%) female, the ECMO time was (120.1±72.4) h in this group. The proportion of tracheal intubation and continuous renal replacement therapy in the survivor group and dosage of norepinephrine within 24 h after ECMO implantation were significantly less than in non-survival group (all P<0.05). There was no significant difference in all efficacy related biochemical indexes between two groups before ECMO use. The levels of lactic acid, procalcitonin, creatinine, alanine aminotransferase, aspartate aminotransferase, creatine kinase-MB, cardiac troponin I and N-terminal B-type natriuretic peptide prosoma were significantly less in survival group than in non-survival group at 24 h after the use of ECMO (all P<0.05). Results of multivariate logistic regression analysis showed that the higher 24 h change rate of creatinine (OR=0.587, 95%CI 0.349-0.986, P=0.044) and creatine kinase-MB (OR=0.177, 95%CI 0.037-0.841, P=0.029) were positively correlated with reduced risk of in-hospital mortality. The central hemorrhage and acute kidney injury in survival group were less than in non-survivor group (P<0.05). Conclusions: After 24 h early use of ECMO in FM patients, the improvement of various efficacy related biochemical test indexes in the survival group was better than that in the non-survival group. Faster reduction of creatine kinase-MB and creatinine values within 24 h ECMO use is positively correlated with reduced risk of in-hospital mortality in adult patients with FM.

Objective: To investigate the expression of vasculogenic mimicry (VM) in endometrial carcinoma tissues and its rela-tionship with the clinicopathologic features and prognosis of the disease. Methods: A total of 267 paraffin-embedded endometrial carci-noma specimens of patients with complete follow-up data were collected from the Shijiazhuang Bethune International Peace Hospital between January 2005 and June 2014. CD31-PAS dual staining was performed to identify the VM structure. Tissue samples were then divided into VM-positive and VM-negative groups. CD133 expression was detected by immunohistochemical streptavidin peroxidase method. Results: Among the 267 endometrial carcinoma patients, 65 cases (24.3%) were VM positive. VM formation was closely corre-lated with the International Federation of Gynecology and Obstetrics Staging (χ2=9.987, P=0.002), histodifferentiation grade (χ2=11.795, P=0.001), myometrial invasion depth (χ2=5.499, P=0.019), vascular cancer embolus (χ2=22.599, P<0.001), and lymph node me-tastasis (χ2=7.848, P=0.005). Kaplan-Meier survival curve analysis showed that survival time was significantly shorter in the VM-posi-tive group (median survival time was 51 months) than in the VM-negative group (median survival time was 100 months) (χ2=70.973, P<0.001). Moreover, CD133 expression was significantly higher in the VM-positive group [75.4% (49/65)] than in the VM-negative group [58.9% (119/202)] (χ2=5.720, P=0.017). Conclusion: VM is closely correlated with the pathogenesis, development, and malignancy of endometrial carcinoma. Furthermore, VM is one of the important indexes influencing the prognosis of this disease. Therefore, CD133-positive cells may contribute to VM formation.
Résumé
It is held by some of the researches that the "16 collaterals" is composed of the "15 collaterals" and "the major collateral of stomach". And it is included into the textbook that Xuli, the major collateral of stomach, is the pulsation point at the cardiac region. Xuli is often explained as the empty portion of the human body by many researches. Through analysis and summarization of the related theory of the major collateral of stomach, the above mentioned opinion is discussed. And the understanding on the major collateral of stomach is deepened. As a result, it is concluded that count the major collateral of stomach into the 16 collaterals together with the 15 collaterals is inadvisable. The real pulsation point at the cardiac region locates under the left breast. And the real meaning of Xuli is "extending in all directions".

OBJECTIVE To understand the pathogenicity of Staphylococcus epidermidis causing urinary tract infection. METHODS Thirty five isolates were collected in the patients with urinary tract infection during 2003-2004 to test the minimal inhibitory concentration(MIC) to erythromycin,ampicillin,cefoxitin,ceftriaxone,teicoplanin,ciprofloxacin,tetracycline,trimethoprim-sulfamethoxazole and vancomycin.The genes of ermA,ermB,ermC,msrA,mecA,and icaA were amplified by PCR.The biofilm producing of the isolates was determined by the quantitative method.The pulsed-field gel electrophoresis(PFGE) was used to discriminate the homology among the isolates. RESULTS Among the isolates,MRSE accounted for 71.4%.The antibiotic susceptibility to erythromycin,ampicillin,ceftriaxone,ciprofloxacin,tetracycline and trimethoprim-sulfamethoxazole were 22.8%,6.34%,34.9%,26.9%,44.4% and 62.2%,respectively,whereas to teicoplanin and vancomycin were 99.2% and 100%.All the isolates resistant to cefoxitin carried mecA.ermC Was the predominant determinant among the erythromycin resistant isolates.Among the 14 icaA positive isolates,10 isolates were biofilm producing.All the isolates were classified into 18 types by PFGE. CONCLUSIONS The high and multiple antibiotic resistance of S.epidermidis isolates causing urinary tract infection were shown.The detection of icaA gene in clinical S.epidermidis isolates was a signal of their pathogenicity.
