OBJECTIVE To compare the effect of traditional swab sampling method on etiological surveillance of in-fectious diseases for large-scale object surfaces in hospitals and validate the samples processing method based on pre-wet anti-static fabric and modified polyethylene glycol(PEG)precipitation enrichment technology so as to im-prove the capability of early warning of infectious diseases and optimize the environmental surveillance program in the hospitals.METHODS The on-site surveillance was carried out for 8 times in 3 public hospitals(Shenzhen Longgang People's Hospital,the Second People's Hospital of Longgang and Longgang Maternal and Child Health Hospital)from May 2024 to Mar.2025.Totally 23 types of respiratory tract pathogens(18 types of viruses,5 type of pathogenic bacteria)and 6 types of gastrointestinal tract pathogens were simultaneously detected by means of fluorescent quantitative polymerase chain reaction(PCR);the actual isolation rates,etiological spectrum and cycle threshold(Ct)value were compared.The acrylic plate added with standards of different loads of H1NI influ-enza viruses was used as model for laboratory evaluation.The minimum detection limit,sensitivity and repeatabili-ty were observed and compared between the methods.RESULTS The minimum detection limit of both methods was 6.0 × 104 copies/ml,however,the positive rate of nucleic acid testing of the pre-wet fabric method was 100.00％(3/3),higher than 33.33％(1/3)of the swab method;when the low viral load was 6.0× 105 copies/ml,the average concentration of viral nucleic acid of the pre-wet fabric method(X-Ct=36.59)was higher,with the re-peatability(CV=0.99％,＜3.14％)better.The results of the on-site surveillances showed that the total isolation rates of pathogens of the pre-wet fabric method ranged between 42.84％and 64.27％,higher than between 10.71％and 21.43％of the swab method,with the isolated pathogens more abundant,the Ct value lower(P＜0.05).CONCLUSION The pre-wet fabric sampling enrichment method integrated with anti-static fabric sampling and PEG enrichment technology shows higher sensitivity and stability in the etiological surveillance of large-scale object surfaces,raising the isolation rate.

Objective:To explore the chain mediating role of general self-efficacy and humanistic care competence between oncology nurses' empathy and medical narrative competence, with a view to informing the development of targeted medical narrative competence enhancement strategies.Methods:Convenience sampling was used to select 1 104 oncology nurses from 17 ClassⅢ Grade A hospitals in Yunnan Province from May to August 2023 for the study. The General Information Questionnaire, Narrative Competence Scale, Chinese version of the Jefferson Scale of Empathy, Caring Ability Inventory, and General Self-Efficacy Scale were used to survey oncology nurses. Pearson correlation was used to analyze the correlation among oncology nurses' general self-efficacy, empathy, humanistic care competence, and medical narrative competence. Mediating effects were analyzed using Model 6 in the SPSS macro program PROCESS 4.0 plug-in. Bootstrap method was used to repeat the sampling 5 000 times for the chained mediating effect test.Results:A total of 1 104 questionnaires were distributed and the number of valid questionnaires recovered was 931, with a valid recovery rate of 84.33% (931/1 104). Among 931 oncology nurses, the scores of Narrative Competence Scale, Caring Ability Inventory, Chinese version of Jefferson Scale of Empathy, and General Self-Efficacy Scale were (151.52±17.61), (191.68±18.80), (95.31±13.96), and (27.59±6.02), respectively. There was a positive two-by-two correlation among oncology nurses' medical narrative competence, empathy, humanistic care competence, and general self-efficacy ( P<0.01). General self-efficacy and humanistic care competence acted as chain mediators between oncology nurses' empathy and medical narrative competence, with the mediating effect accounting for 43.13% of the total effect. Conclusions:General self-efficacy and humanistic care are mediating variables between oncology nurses' empathy and medical narrative competence. Nursing managers should focus on the cultivation of nurses' empathy, stimulate nurses' self-efficacy, and promote the practice of nursing humanistic care, which in turn improves oncology nurses' medical narrative competence and the quality of nursing services.

Objective:To explore the newborn birth weight and its influencing factors of polycystic ovary syndrome (PCOS) patients during fresh embryo transfer cycle.Methods:In this retrospective cohort study, the clinical data of 5087 patients with singleton live births who underwent in vitro fertilization and embryo transfer (IVF-ET) in the Reproductive Medicine Center of the First Affiliated Hospital of Zhengzhou University from January 2014 to December 2019 were analyzed. The patients were categorized into PCOS group ( n=1095) and non-PCOS group (referred to as control group, n=3992) according to the cause of infertility. The general conditions and birth weight of the two groups were compared, and logistic regression analysis was performed to identify the factors affecting birth weight. Results:For embryo transfer on the 3rd day (day 3, D3), the clinical pregnancy rate [69.0% (1248/1808)] and the implantation rate [49.0% (1742/3555)] in PCOS group were higher than those in control group [59.1% (5661/9572) and 42.0% (7577/18 040), all P<0.001], while the live birth rate [37.0% (670/1810)] was lower than that in control group [49.0% (4697/9585), P<0.001]. For blastocyst transfer on the 5th day (day 5, D5), the implantation rate [63.1% (500/793)] and the live birth rate [54.0% (425/787)] in PCOS group were higher than those of control group [59.0% (1066/1806), P=0.042; 48.0% (876/1825), P=0.013]. The birth weight of the infants [(3 459.76±527.11) g] and the proportion of overweight infants [14.35% (61/425)] in PCOS group of D5 blastocyst transfer were higher than those in control group [(3 391.61±521.38) g, P=0.028; 8.22% (72/876), P<0.001] and PCOS group of D3 embryo transfer [(3 389.24±555.06) g, P=0.018; 9.25% (62/670), P=0.009], but the proportion of low weight infants [2.35% (10/425)] was lower than that in control group of the D5 blastocyst transfer [4.91% (43/876), P=0.029] and PCOS group of D3 embryo transfer [4.78% (32/670), P=0.042]. Logistic regression analysis showed that the level of female body mass index (BMI) affects the birth weight of D5 blastocyst transfer ( OR=1.12, 95% CI=0.052-0.175, P<0.001). Developmental timing of transferred embryos affects birth weight in PCOS patients ( OR=1.52, 95% CI=0.019-0.819, P=0.040). Conclusion:For PCOS patients, choosing D5 blastocyst transfer can obtain a higher rate of live birth and a lower proportion of low birth weight infants. It is recommended that blastocyst transfer be performed for PCOS patients in fresh cycle.

Purpose: Drug resistance is one of the main causes of chemotherapy failure in patients with small cell lung cancer (SCLC), and extensive biological studies into chemotherapy drug resistance are required. Materials and Methods: In this study, we performed lncRNA microarray, in vitro functional assays, in vivo models and cDNA microarray to evaluate the impact of lncRNA in SCLC chemoresistance. Results: The results showed that KCNQ1OT1 expression was upregulated in SCLC tissues and was a poor prognostic factor for patients with SCLC. Knockdown of KCNQ1OT1 inhibited cell proliferation, migration, chemoresistance and promoted apoptosis of SCLC cells. Mechanistic investigation showed that KCNQ1OT1 can activate transforming growth factor-β1 mediated epithelial-to-mesenchymal transition in SCLC cells. Conclusion Taken together, our study revealed the role of KCNQ1OT1 in the progression and chemoresistance of SCLC, and suggested KCNQ1OT1 as a potential diagnostic and prognostic biomarker in SCLC clinical management.

Objective To analyze stress distributions of alveolar bone around implants with different types of implant thread shapes and thread depths during dental immediate implantation, so as to provide references for the design and selection of implants. Methods The simplified model of mandible bone block, implants and mandibular molar were established by Geomagic Studio, SolidWorks and ANSYS Workbench, and vertical and oblique loads were applied on this model, respectively. Stress distributions on implants with different thread shape and thread depth as well as alveolar bone around implants were calculated. Results Under vertical loading, the peak stresses of implants, cortical bone and cancellous bone were in the range of 120.51-129.63 MPa, 9.94-13.25 MPa and 3.92-8.01 MPa, respectively. And the stress of cortical bone around V-shaped, rectangular, buttress or reverse buttress implant remained stable in the range of 0.40-0.45 mm thread depth. Under oblique loading, the peak stresses of implants, cortical bone and cancellous bone were in the range of 220.23-286.51 MPa, 33.39-45.08 MPa, 4.96-12.5 MPa, respectively. Among the models, V-shaped, buttress, reverse buttress implant with 0.45 mm thread depth showed the minimum stress. Conclusions The V-shaped, buttress or reverse buttress implant with a thread depth of 0.45 mm, or the rectangular implant with a thread depth of 0.40 mm had better biomechanical properties.
