Objective:To analyze the current status of red blood cell transfusion in very preterm infants (VPI) (gestational age at birth <32 weeks) from Chinese Neonatal Network (CHNN) in 2022.Methods:This cross-sectional study was based on the CHNN VPI cohort. It included 6 985 VPI admitted to CHNN 89 participating centers within 24 hours after birth in 2022. VPI with major congenital anomalies or those transferred to non-CHNN centers for treatment or discharged against medical advice were excluded. VPI were categorized based on whether they received red blood cell transfusions, their gestational age at birth, the type of respiratory support received during transfusion, and whether the pre-transfusion hemoglobin levels exceeded the thresholds. General characteristics, red blood cell transfusion rates, number of transfusions, timing of the first transfusion, and pre-transfusion hemoglobin levels were compared among different groups. The incidence of adverse outcomes between the group of VPI who received transfusions above the threshold and those who received transfusions below the threshold were compared. Comparison among different groups was conducted using χ2 tests, Kruskal-Wallis H tests, Mann-Whitney U test, and so on. Trends by gestational age at birth were evaluated by Cochran-Armitage tests and Jonckheere-Terpstra tests for trend. Results:Among the 6 985 VPI, 3 865 cases(55.3%) were male, with a gestational age at birth of 30.0 (28.6, 31.0) weeks and a birth weight of (1 302±321) g. Overall, 3 617 cases (51.8%) received red blood cell transfusion, while 3 368 cases (48.2%) did not. The red blood cell transfusion rate was 51.8% (3 617/6 985), with rates of 77.7% (893/1 150) for those born before 28 weeks gestational age and 46.7% (2 724/5 835) for those born between 28 and 31 weeks gestational age. A total of 9 616 times red blood cell transfusions were administered to 3 617 VPI, with 632 times missing pre-transfusion hemoglobin data, and 8 984 times included in the analysis. Of the red blood cell transfusions, 25.6% (2 459/9 616) were administered when invasive respiratory support was required, 51.3% (4 934/9 616) were receiving non-invasive respiratory support, while 23.1% (2 223/9, 616) were given when no respiratory support was needed. Compared to the non-transfusion group, the red blood cell transfusion group had a higher rate of pregnancy-induced hypertension in mothers, lower rates of born via cesarean section and mother′s antenatal steroid administration, smaller gestational age, lower birth weight, a higher proportion of small-for-gestational-age, multiple births, and proportions of Apgar score at the 5 th minute after birth ≤3 (all P<0.05). They were also less likely to be female, born in hospital or undergo delayed cord clamping (all P<0.01). Additionally, higher transport risk index of physiologic stability score at admission were observed in the red blood cell transfusion group ( P<0.001). The number of red blood cell transfusion was 2 (1, 3) times, with the first transfusion occurring at an age of 18 (8, 29) days, and a pre-transfusion hemoglobin level of 97 (86, 109) g/L. For VPI ≤7 days of age, the pre-transfusion hemoglobin levels for invasive respiratory support, non-invasive respiratory support, or no respiratory support, respectively, with no statistically significant differences between groups ( H=5.59, P=0.061). For VPI aged 8 to 21 days and≥22 days, the levels with statistically differences between groups (both P<0.01). Red blood cell transfusions above recommended thresholds were observed in all respiratory support categories at different stages of life, with the highest prevalence in infants aged 8 to 21 days and≥22 days who did not require respiratory support, at 90.1% (264/273) and 91.1%(1 578/1 732), respectively. The rate of necrotizing enterocolitis was higher in the above-threshold group ( χ2=10.59, P=0.001), and the duration of hospital stay was longer in the above-threshold group ( Z=4.67, P<0.001) compared to the below-threshold group. Conclusions:In 2022, the red blood cell transfusion rate was relatively high among VPI from CHNN. Pre-transfusion hemoglobin levels frequently exceeded recommended transfusion thresholds.

OBJECTIVE To explore the effects of narrative pharmacy management on medication compliance， negative emotions， and quality of life in patients with cardiovascular disease complicated with negative emotions. METHODS A total of 49 patients with drug use problems and negative emotions attending the cardiovascular pharmacy clinic of Wuhan First Hospital from February to August 2023 were selected as the study objects， narrative pharmacy model was applied for patient management during their visits； pharmaceutical care and emotional management were performed after 2 weeks of treatment and a follow-up visit was conducted to evaluate and record the management effect one month later. RESULTS Adopting a narrative pharmacy management model， 49 patients were involved in 114 drug related consultation questions. Compared with the visit， after one month of management， the number of medication types taken by patients significantly decreased [4.00 （2.00， 6.00） vs. 3.00 （1.50， 5.00）， P＜0.05]， the incidence of adverse reactions significantly decreased （32.65% vs. 2.04%， P＜0.001）， the rate of blood pressure and lipid compliance significantly increased （30.61% vs. 95.92%， P＜0.001）， and the score of the patient’s medication compliance significantly improved （[ 3.94±2.44） vs. （6.78±2.07）， P＜0.01]. The depression score significantly decreased [3.00 （2.00， 4.50） vs. 2.00 （0.00， 3.00）， P＜0.001]， the anxiety score significantly reduced [3.00 （2.00， 4.50） vs. 1.00 （0.00， 2.00）， P＜0.001]， quality of life score was significantly improved [22.00 （19.00， 22.00） vs. 23.00 （23.00， 24.50）， P＜0.01]. In the satisfaction survey， there was a slight increase in the overall satisfaction proportion （91.84% vs. 97.96%， P＞0.05）. CONCLUSIONS The application of narrative pharmacy in cardiovascular pharmacy clinic can improve patient compliance， reduce adverse drug reactions， enhance the effectiveness of drug treatment， avoid drug interactions， effectively improve the anxiety and depression， and ultimately improve the quality of life.

A 65-year-old male patient was admitted for recurrent lymph node enlargement for 5 years and elevated creatinine for 6 months. This patient was diagnosed with angioimmunoblastic T-cell lymphoma 5 years ago and underwent multiple lines of anti-tumor therapy, including cytotoxic chemotherapy; epigenetic modifying drugs such as chidamide and azacitidine; the immunomodulator lenalidomide; and targeted therapy such as rituximab, a CD20-targeting antibody, and brentuximab vedotin, which targets CD30. Although the tumor was considered stable, multiple virus activation (including BK virus, JC virus, and cytomegalovirus) accompanied by the corresponding organ damage (polyomavirus nephropathy, cytomegalovirus retinitis, and progressive multifocal leukoencephalopathy) occurred during anti-tumor treatment. Anti-tumor therapy was suspended and ganciclovir was used. The serum viral load decreased and organ functions were stabilized. The purpose of this report was to raise clinicians′ awareness of opportunistic virus reactivation during anti-tumor treatment.

Objective To explore the potential pathogenic genes of intestinal metaplasia.Methods Twenty-one patients with intestinal metaplasia admitted to the Department of Gastroenterology at the Second Affiliated Hospital of Anhui University of Chinese Medicine from January,2022 to June,2022,and 21 healthy subjects undergoing gastroscopic examination during the same period were enrolled in this study.All the participants underwent gastroscopy and pathological examination,and gastric tissue samples were collected for transcriptome sequencing to screen for differentially expressed genes(DEGs).The biological functions of the DEGs were analyzed using bioinformatics analysis,and qRT-PCR was used to validate the results.Results Transcriptomic sequencing identified a total of 1373 DEGs,including 827 upregulated and 546 downregulated ones.The top 6 upregulated genes(AGMAT,CCL25,FABP1,CDX1,SPINK4,and MUC2),ranked based on their significance and average expression level,were selected for validation,and qRT-PCR showed significant upregulation of their mRNAs in the gastric tissues of patients with intestinal metaplasia(P<0.05).Conclusion AGMAT,CCL25,FABP1,CDX1,SPINK4,and MUC2 participate in the occurrence and development of intestinal metaplasia,and may serve as potential biomarkers for diagnosing intestinal metaplasia.

In the field of healthcare service, it is crucial to optimize medical innovation services by combining the preferences of health service providers and demanders (i.e., stakeholders). The best-worst scaling (BWS) method is a recently developed stated preference method for assessing preferences with distinctive advantages. Nevertheless, there is a lack of a comprehensive introduction to stakeholder preference assessment using BWS, thus constraining its applications and promotion. This paper introduces the process of using BWS to assess service providers' preferences for the Shared Medical Appointment for diabetes (SMART), an integrated healthcare service of medicine and health management, in the hope of providing reference for researchers for promoting the use of BWS in implementation research.

Objective:To explore the composition of oral microbiome in patients of long-term survival after liver transplantation, and compare the diversity and distribution of oral microbiome in liver transplant patients with or without liver cancer.Methods:This is a cross-sectional study. Clinical data of 20 patients of long-term survival after liver transplantation from Beijing Chaoyang Hospital Affiliated to Capital Medical University from July 2023 to October 2023 were continuously collected, including 13 males and 7 females, aged 55 (48, 60) years. There were eight patients with hepatocellular carcinoma (HCC) undergoing liver transplantation and 12 non-HCC liver transplant patients. Oral microbiome was analyzed by 16S rDNA gene sequencing, and the diversity analysis and LEfSe analysis were performed.Results:The top ten groups of bacteria in the HCC and non-HCC liver transplant patients were both Bacteroidota, Firmicutes, Proteobacteria, Actinobacteria, Fusobacteriota, Patescibacteria, Campylobacterota, Cyanobacteria, spirochaetota, and Aenigmarchaeota. The top ten genus levels of bacteria in the HCC and non-HCC liver transplant patients were both Haemophilus, Porphyromonas, Gemella, Fusobacterium, Actinomyces, Prevotella, Rothia, Streptococcus, Neisseria. By LEfSe analysis, we found the enrichment of Flavobacteriales, Flavobacteriaceae, Capnocytophaga, Mogibacterium_timidum, Capnocytophaga_leadbetteri, Campylobacter_showae in the HCC group, while the enrichment of Veillonella_atypica, Prevotella_histicola in the non-HCC group.Conclusion:The main microbiome was similar between HCC and non-HCC liver transplant patients, but there were also some differences in microbiome communities.

Objective To construct a pelvic floor muscle training program for patients undergoing radical prostatectomy,and to provide a reference for clinical practice.Methods The evidence related to pelvic floor muscle training in patients undergoing radical prostatectomy was systematically searched and the quality was evaluated.The draft of pelvic floor muscle training program for patients undergoing radical prostatectomy was constructed based on the KAP theory and it was demonstrated and revised by expert meetings.From February to March 2023,Delphi method was used to determine the final scheme.37 patients were selected as the control group and 38 patients as the experimental group to implement the scheme and evaluate the application effect.Results 2 rounds of Delphi consultations were conducted among 17 experts,and the recovery rate of the questionnaire was 100％.The expert authority coefficient was 0.89.The Kendall harmony coefficients of the importance and feasibility of the second round of consultation were 0.270 and 0.209(P＜0.001).The coefficient of variation of importance and feasibility of items were 0～0.18 and 0～0.20.The final program included 3 first-level items,8 second-level items and 29 third-level items.1 month after surgery,there was no significant difference in urinary incontinence score(P=0.242)and there was significant difference in pelvic floor muscle training compliance(P=0.011)between 2 groups.Conclusion The program was applied preliminary in clinical practice and it was confirmed with scientific and practical meaning,so it can provide a reference for clinical nursing.

Objective To explore the related risk factors of hypokalemia in elderly patients with acute cerebral hemorrhage(ACH),and construct a risk prediction model based on logistic regres-sion.Methods A total of 190 elderly ACH patients treated in Foshan Hospital of Traditional Chi-nese Medicine from June 2022 to May 2024 were enrolled as study objects,and were divided into hypokalemic group(potassium＜3.5 mmol/L,n=51)and normal group(potassium 3.5-5.5 mmol/L,n=139)according to whether hypokalemia occurred.Logistic regression model was used to analyze the risk factors of hypokalemia in the elderly ACH patients.Based on the identified risk factors,a comprehensive index model was constructed.ROC curve was drawn to analyze the diag-nostic value of the index for occurrence of hypokalemia in the patients.Results Larger female ra-tio,higher NIHSS score at admission,elevated urea nitrogen and blood creatinine at admission,and higher glomerular filtration rate(GFR)≤60 ml/min,and ratio of using hydrochlorothiazide＞20 mg/d were observed in the hypokalemic group than the normal group(P＜0.01).Univariate logistic regression analysis showed that female,NIHSS score at admission,urea nitrogen at ad-mission,serum creatinine at admission,GFR ≤60 ml/min,and hydrochlorothiazide dose＞20 mg/d were risk factors for hypokalemia in the ACH patients(P＜0.05,P＜0.01).Multivariate lo-gistic regression analysis indicated that female,NIHSS score at admission,GFR ≤60 ml/min,and hydrochlorothiazide dose＞20 mg/d were independent risk factors for hypokalemia in the elderly ACH patients(OR=6.393,95％CI:2.138-19.112,P=0.001;OR=3.123,95％CI:2.161-4.513,P=0.000;OR=3.327,95％CI:1.137-9.736,P=0.028;OR=3.111,95％CI:1.083-8.933,P=0.035).ROC curve analysis revealed that the AUC values of female,NIHSS score at admission,GFR,hydrochlorothiazide dose and comprehensive index in predicting hypokalemia in elderly ACH patients were 0.621,0.897,0.601,0.613 and 0.857,with a sensitivity of 52.90％,76.50％,49.00％,54.90％and 72.50％,and a specificity of 71.20％,88.50％,71.20％,67.60％and 87.80％,respectively.Conclusion Female,NIHSS score at admission,GFR ≤60 ml/min,and hydrochlorothiazide dose＞20 mg/d may affect the occurrence of hypokalemia in elderly ACH pa-tients,and our comprehensive index model based on these risk factors has high performance in predicting the occurrence of hypokalemia in elderly ACH patients.

Objective:To compare the differences in surgical safety and postoperative cosmetic effects between endoscopic nipple-sparing mastectomy with immediate prepectoral prosthesis breast reconstruction and conventional nipple-sparing mastectomy with immediate subpectoral prosthesis breast reconstruction.Methods:The clinical data of early breast cancer patients admitted to the Department of Breast Surgery of Peking University Peoples Hospital from Oct 1, 2022 to Sep 13, 2023 was retrospectively analyzed.Results:According to the surgical method, the patients were divided into endoscopic surgery group (30 cases) and traditional surgery group (46 cases). There were no significant differences in the basic clinicopathological data, and the number of sentinel lymph nodes taken and axillary lymph nodes dissected between the patients in two groups (all P>0.05). Compared with that in traditional surgery group, the patients in endoscopic surgery group had longer operation time and more wound drainage volumes 3 days after surgery (all P<0.05). There was no significant differences in the probability of postoperative complications between the patients in two groups (all P>0.05), however, the proportion of nipple-areola complex necrosis in patients of endoscopic surgery group (10.0%) was lower than that of traditional surgery group (26.1%). Conclusions:The single-port insufflation technique-assisted endoscopic nipple-sparing mastectomy with immediate prepectoral prosthesis breast reconstruction maximize the cosmetic effect. Under the premise of strict selection of indications, it can be an optional surgical method.

Objective This study aimed to investigate the role and mechanism of atractylenolide Ⅰ in inhibiting XPOT proliferation and invasion in gastric cancer cells.Methods This study included exploration of XPOT expression in gastric cancer tissues,analysis of gene expression data from GC patients in TCGA and GEO databases,as well as various cellular assays to detect the ability of cancer cells to proliferate,migrate,and invade.Protein expression levels of XPOT,SKP2,CyclinA,and P27 mRNA were also detected by qPCR and Western Blot.Results Analysis confirmed that XPOT was highly expressed in gastric cancer tissues,indicating a poor prognosis.In vitro studies revealed that AT-1 inhibits the proliferation and invasion ability of GC cells;XPOT down-regulation also inhibits these abilities.Furthermore,AT-1 down-regulates the expression of XPOT which then regulates SKP2,P27,and CyclinA-ultimately inhibiting the proliferation and invasion of gastric cancer cells through the regulation of the XPOT pathway.Conclusion The overexpression of XPOT in gastric cancer tissues can indicate a poor prognosis.Atractylenolide Ⅰ down-regulates the XPOT-regulated ubiquitination-proteasome pathway to inhibit proliferation and invasion of gastric cancer cells.
