OBJECTIVE To investigate the application and influencing factors of sodium-dependent glucose transporters 2 inhibitors（SGLT-2i） in patients with heart failure with preserved ejection fraction（HFpEF） in the real world. METHODS Data from 358 patients with HFpEF who were hospitalized at the First Affiliated Hospital of Chongqing Medical University from May 2023 to May 2024 were retrospectively collected. The patients were divided into the SGLT-2i group and the non-SGLT-2i group based on whether they were prescribed SGLT-2i upon discharge. Baseline characteristics， comorbidities， and differences in drug treatment were compared between the two groups. Based on univariate analysis， multivariate Logistic regression analysis was performed to identify independent influencing factors of SGLT-2i use in patients with HFpEF， followed by further stratified analysis. RESULTS Among 358 HFpEF patients， the overall utilization rate of SGLT-2i was 33.5%. Combined with type 2 diabetes [OR＝9.063，95%CI（4.924-16.679） ] ， atrial fibrillation [OR＝3.135，95%CI（1.590-6.178） ] ， coronary artery heart disease [OR＝1.888，95%CI（1.072-3.327） ] and the use of loop diuretics [OR＝3.822， 95%CI （1.588-9.200） ] were all independent influencing factors for the use of SGLT-2i in patients with HFpEF （ P ＜0.05）. The results of the stratified descriptive analysis were consistent with those of the multivariate analysis， showing a higher utilization rate of SGLT-2i among patients with concomitant T2DM，atrial fibrillation， coronary artery heart disease， and those receiving loop diuretics （ P ＜0.05）； whereas the utilization rate of SGLT-2i was comparable across patients with different levels of renal function （ P ＞0.05）. CONCLUSIONS In the real-world clinical practice， the utilization of SGLT-2i in patients with HFpEF remains suboptimal， and treatment coverage still needs to be improved. Their use of SGLT-2i is primarily influenced by the presence of type 2 diabetes， atrial fibrillation， coronary artery heart disease， and the use of loop diuretics.

IL-32 is a multifunctional cytokine with both pro-inflammatory and anti-inflammatory properties.It has been proved that expression of IL-32 increases with progression of gastric mucosal diseases and severity of gastric cancer(GC),thus participating in process of gastric"inflammation-cancer"transformation.However,how IL-32 affects malignant transformation of gastric"inflamma-tion-cancer"and finally leads to adverse outcome of GC invasion and migration is still controversial.In order to better clarify regulatory effect and possible mechanism of abnormal expression of IL-32 on different histopathological stages of gastric"inflammation-cancer"transformation,and to explore new directions and breakthroughs in molecular mechanism of early truncation and treatment of gastric precancerous lesion(GPL),we searched literatures related to IL-32 in six authoritative databases at home and abroad,such as Pubmed,Web of Science and CNKI,in past 30 years.It was found that pathogenicity or protective function of IL-32 in different histo-pathological stages of gastric"inflammation-cancer"transformation depended on its different subtypes,secretory forms,surrounding cytokine environment,disease status and genetic factors.IL-32 may regulate polarization of macrophages through NF-κB,MAPK,COX2,PR3,IDO,NOD,PKCδ,FAK and STAT3,amplify or inhibit chronic inflammatory stimulation of gastric mucosa,and thus participate in process of gastric"inflammation-cancer"transformation.Our new understanding of role of IL-32 in different stages of Cor-rea cascade may contribute to development of cytokine-directed therapy,and therapy aimed at regulating different alternative splicing subtypes of IL-32 and targeting IL-32 signals can be used as a new strategy for medical treatment of GPL and GC in future.

Objective To explore the effect of M2 polarization of macrophages on intestinal metaplasia(IM)of gastric mucosa and its therapeutic target,so as to provide new ideas and directions for the prevention and treatment of IM with traditional Chinese medicine.Methods The data sets related to IM and macrophage M2 polarization were downloaded from the public database,and the correlation between IM and macrophage M2 polarization was further expounded by immune infiltration analysis,gene correlation analysis,functional enrichment analysis,protein interaction network and experimental verification.Finally,the obtained hub genes were mapped with Coremine Medical platform to predict the effective traditional Chinese medicine and treatment of IM.Results Immunoinfiltration and immunofluorescence analysis showed that the expression of macrophage M2 polarization markers CD68+CD163+(P=0.0394)and CD68+CD206+(P=0.002)in IM group was significantly higher than that in normal group,and the infiltration level of M2 macrophages in IM group was significantly higher than that in normal group(P＜0.05).IM related marker genes(CDX1,MUC2,TFF3)were positively correlated with macrophage M2 polarization markers(CD209,ARG1,MSR1,STAT3,IL32,SELENOP)(P＜0.05).Functional enrichment analysis showed that the differential genes co-expressed by IM and macrophage M2 polarization were closely related to molecular biological functions such as carboxylic acid transmembrane transporter activity and organic acid transmembrane transporter activity.Finally,7 pivotal differential genes co-expressed by IM and macrophage M2 were screened,which were TRAF1,TNFRSF12A,BIRC3,TNFRSF11A,CTSV,SLC29A1 and CDA,respectively.According to the prediction of traditional Chinese medicine,23 kinds of traditional Chinese medicine for IM were predicted,which could be classified into 14 categories according to their efficacy,among which heat-clearing antidote appeared most frequently,followed by drugs for tonifying qi and painkillers for promoting blood circulation drugs.Conclusion Macrophage M2 polarization may be involved in the pathogenesis and development of IM through exocrine pathway.IM and seven hub genes co-expressed by macrophage M2 polarization(TRAF1,TNFRSF12A,BIRC3,TNFRSF11A,CTSV,SLC29A1 and CDA)and IM specific molecules CDX1,MUC2 and TFF3 may be associated with each other and participate in the progression of IM.The therapeutic method of Jianpi Huayu Jiedu is the core treatment of IM in traditional Chinese medicine.Starting from the M2 polarization of macrophages,it is expected to become a new direction and breakthrough in clinical prevention and treatment of IM.

Objective:To investigate the influence of liver drainage volume on overall survival time in patients with unresectable malignant hilar bile duct obstruction.Methods:Data of 633 patients with unresectable malignant hilar bile duct obstruction (BismuthⅡ-Ⅳ) who underwent endoscopic stent drainage in 3 endoscopy centers from January 2002 to May 2019 were retrospectively analyzed. Main observation indicators included clinical success rate, stent patency, overall survival, the effective liver drainage volume, and complication incidence.Results:The clinical success rates of patients with liver drainage volume <30%, 30%-50%, and >50% were 56.8% (25/44), 77.3% (201/260) and 84.2% (277/329) respectively. The incidences of early cholangitis were 31.8% (14/44), 18.8% (49/260) and 16.1% (53/329). The median stent patency time was 4.5 (95% CI: 1.8-7.2) months, 5.6 (95% CI: 5.0-6.2) months and 6.6 (95% CI: 5.2-8.0) months. The overall survival time was 2.4 (95% CI: 1.8-3.0) months, 4.0 (95% CI: 3.4-4.6) months and 4.9 (95% CI:4.4-5.4) months, respectively. The clinical success rate ( χ 2=8.28, P=0.012), median stent patency period ( χ 2=18.87, P=0.015) and overall survival time ( χ 2=6.93, P=0.024) of 30%-50% liver drainage volume group were significantly higher than those of <30% group. Further multivariate cox regression analysis showed that the disease type (hepatocellular carcinoma VS hilar cholangiocarcinoma: HR=1.50, 95% CI:1.18-1.91, P=0.001; gallbladder carcinoma VS hilar cholangiocarcinoma: HR=1.45, 95% CI:1.14-1.85, P=0.002; metastatic cholangiocarcinoma VS hilar cholangiocarcinoma: HR=1.48, 95% CI:1.08-2.04, P=0.015), bilirubin level >200 μmol/L ( HR=1.35, 95% CI:1.14-1.60, P<0.001),metal stents ( HR=0.67, 95% CI:0.56-0.79, P<0.001), liver drainage volume (volume 30%-50% VS <30%: HR=0.64, 95% CI: 0.45-0.90, P=0.010; volume>50% VS <30%: HR=0.58, 95% CI:0.41-0.81, P=0.002) and anti-tumor therapy ( HR=0.51, 95% CI:0.42-0.61, P<0.001) were independent predictors for overall survival time of patients with unresectable malignant hilar bile duct obstruction. Conclusion:When endoscopic stent drainage is performed for patients with unresectable malignant hilar bile duct obstruction, at least 30% liver volume is required for better overall survival. In addition, the use of metal stent drainage and anti-tumor therapy may increase survival benefits.

Objective:To sort out the current status and development of standardized nursing terminology in China, and reveal research hotspots and trends.Methods:The bibliometric and keyword cluster analysis and burstiness detection were performed using CiteSpace software on periodicals of standardized nursing terminology in China National Knowledge Infrastructure, WanFang Database and VIP Database from their establishment to December 31, 2021.Results:A total of 1 761 articles were included.

Objective:To investigate the application value of different metal stents place-ment position in endoscopic drainage of malignant hilar bile duct obstruction.Methods:The retro-spective cohort study was conducted. The clinicopathological data of 300 patients with malignant hilar bile duct obstruction who were admitted to 3 medical centers, including 216 patients in the Third Affiliated Hospital of Naval Medical University, 48 patients in the Xijing Hospital of Air Force Medical University, 36 patients in the First People's Hospital Affiliated to Shanghai Jiaotong University School of Medicine, from January 2012 to January 2019 were collected. There were 164 males and 136 females, aged (67±12)years. All patients were determined to be unresectable by multidisciplinary consultation and underwent endoscopic retrograde cholangiopancreatography. Observation indicators: (1) clinicopathological features of patients; (2) follow-up; (3) analysis of influencing factors for patency time of metal biliary stents and overall survival time of patients. Follow-up was conducted using outpatient examination and telephone interview to detect patency of metal biliary stents and survival of patients up to July 2019 or death of patients. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were expressed as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the rank sum test. Kaplan-Meier method was used to calculate survival rates and draw survival curves, and Log-Rank test was used to conduct survival analysis. COX regression model was used for univariate and multivariate analyses. Factors with P<0.1 in univariate analysis were included in multivariate analysis. Results:(1) Clinicopathological features of patients. Of the 300 patients, 163 cases underwent endoscopic drainage with at least one metal biliary stent' distal portion crossing the duodenal main papilla (hereinafter referred to as crossing papilla), and 137 cases underwent endoscopic drainage with no metal biliary stent' distal portion crossing the duodenal main papilla (hereinafter referred to as no crossing papilla). Age, disease type (hilar cholangiocarcinoma, hepatocellular carcinoma, intrahepatic cholangio-carcinoma, gallbladder carcinoma, metastatic cholangiocarcinoma), metal biliary stents type (unilateral metal biliary stent, bilateral metal biliary stents) of patients with crossing papilla were (68±13)years, 95, 8, 11, 31, 18, 63, 100, respectively. The above indicators of patients with no crossing papilla were (64±12)years, 63, 22, 20, 23, 9, 126, 11, respectively. There were significant differences in the above indicators between patients with crossing papilla and patients with no crossing papilla ( t=2.70, χ2=17.69, 90.79, P<0.05). (2) Follow-up. All the 300 patients were followed up for 5.4(3.1,9.3)months. The patency time of metal biliary stents was 9.0(8.2,9.8)months and 6.4(4.8,8.0)months of patients with crossing papilla and patients with no crossing papilla, showing a significant difference between them ( χ2=8.23, P<0.05). The overall survival time was 5.5(4.2,6.8)months and 5.5(4.3,6.8)months of patients with crossing papilla and patients with no crossing papilla, showing no significant difference between them ( χ2=0.28, P>0.05). (3) Analysis of influencing factors for patency time of metal biliary stents and overall survival time of patients. Results of univariate analysis showed that type of metal biliary stents and the placement position of metal biliary stents were related factors affecting the patency time of metal biliary stents [ hazard ratio( HR)=0.44, 0.60, 95% confidence intervals as 0.30?0.64, 0.42?0.85, P<0.05]. Results of multi-variate analysis showed that bilateral metal biliary stents was an independent protective factor for the patency time of metal biliary stents ( HR=0.46, 95% confidence interval as 0.29?0.72, P<0.05). Results of univariate analysis showed that disease type (intrahepatic cholangiocarcinoma versus hilar cholangiocarcinoma), preoperative serum total bilirubin, type of metal biliary stents, anti-tumor therapy were related factors affecting the overall survival time of patients ( HR=1.05, 1.43, 0.72, 0.61, 95% confidence intervals as 0.70?1.57, 1.12?1.83, 0.55?0.92, 0.47?0.81, P<0.05). Results of multi-variate analysis showed that age >60 years, disease type as hepatocellular carcinoma, preoperative serum total bilirubin >200 μmol/L were independent risk factors for the overall survival time of patients ( HR=1.35, 1.98, 1.46, 95% confidence intervals as 1.02?1.79, 1.40?2.80, 1.13?1.89, P<0.05), and bilateral metal biliary stents, anti-tumor therapy were independent protective factors for the overall survival time of patients ( HR=0.68, 0.60, 95% confidence intervals as 0.53?0.89, 0.45?0.80, P<0.05). Conclusions:Endoscopic drainage with or without metal biliary stents' distal portion crossing the duodenal main papilla is safe and feasible for patients with malignant hilar bile duct obstruction. Bilateral metal biliary stents is an independent protective factor for the patency time of metal biliary stents. Age >60 years, disease type as hepatocellular carcinoma, preoperative serum total bilirubin >200 μmol/L are independent risk factors for the overall survival time of patients, and bilateral metal biliary stents, anti-tumor therapy are independent protective factors for the overall survival time of patients.

Marital quality is closely related to individual health. It is the main reason for many couples to terminate assisted reproductive technology (ART) treatment, otherwise it also has been proved to be significantly related to curative effect of ART. With the development of preimplantation genetic testing (PGT), ART is bound to have a wider range of people to adapt in the future. PGT includes two main processes, in vitro fertilization (IVF) and genetic testing. In addition to traditional infertile couples, couples at high-risk of genetic diseases is also a common indication for PGT, which means that comparing to infertile women or IVF women, marital quality of PGT women is more complicated. Firstly, this review introduced the current methodology on marital quality, and basis of summarizing research results of marital quality of IVF women, according to different indications, we put forward potential problems of marital quality of PGT women. Finally, in the light of domestic research status of marital quality, we referred to some research limitations, in order to provide a theoretical basis for further research on marital quality of PGT women.
