Objective : Objective To investigate the demand for health management and influencing factors among occupational population at high risk of stroke, so as to provide insights into the development of stroke health management strategies among occupational population. Methods: Occupational population aged 40 to 60 years who participated in health examination were sampled from three tertiary hospitals in Luzhou City, Sichuan Province using a quota sampling method in the ratio of 4∶1∶1, from August to December 2020. Participants' blood biochemistry tests and health examination were collected through the examination reports, and the participants at high risk of stroke were screened using the assessment criteria for high-risk of stroke. Participants' general information and demand for health management were collected using questionnaire surveys. In addition, factors affecting the demand for health management were identified using a multivariable logistic regression model. Results: A total of 3 003 people who participated in health examination were investigated, and 1 062 participants met the assessment criteria for high risk of stroke, accounting for 35.36%. There were 1 000 men (94.16%) and 62 women (5.84%), with a mean age of (49.26±4.97) years. There were 414 professional and technical staff (39.50%). There were 709 participants (66.76%) with demand for health management, with the top three in the demand as health checkups (915 participants, accounting for 86.16%), health consultation (601 participants, accounting for 56.60%) and exercise guidance (560 participants, accounting for 52.73%), and 210 participants (19.77%) received health management. Multivariable logistic regression analysis showed that occupational population at high risk of stroke who received health management were more likely to have the demand for health management (OR=2.158, 95%CI: 1.479-3.149). Conclusions The occupational population at high risk of stroke have the demand for health management. Having received health management may affect the demand for health management among occupational population at high risk of stroke.

Objectives:To finely divide the aortic sinus into sections and accurately localize the coronary ostium through CARTO three-dimensional mapping,and to assess the clinical effects of treating aortic sinus cusps premature ventricular contraction(ASC-PVC)and the ablation risk in the corresponding area with zero X-ray radiofrequency ablation. Methods:A total of 66 patients who underwent radiofrequency ablation for ASC-PVC from January 2020 to January 2023 were included in this analysis,patients were divided into experimental group(n=34)and conventional group(n=32).In the conventional group,the CARTO 3 system was used to create an aortic sinus model through the conventional method.The earliest stimulating target was identified by using electrical stimulation mapping(ESM).Radiofrequency ablation treatment was performed after the distance between the target and the coronary ostium was precisely measured by coronary angiography through the hollow tube of the ablation catheter or coronary angiography tube.In the experimental group,the CARTO 3 system was used to build a model of the aortic sinus and the coronary ostium and aortic sinus were divided into sections.The earliest stimulating target was identified by ESM.After localizing coronary ostium through the impedance changing pattern on the ablation catheter tips,catheter ablation was performed with zero X-ray.The data regarding the impedance of the ablation catheter in the aortic sinus were collected.The total operative time,the operative time in the aortic sinus,contrast dosage,X-ray exposure time,immediate and short-term success rates of the operation and complication rates were compared between the two groups.Besides,the distribution of successfully ablated targets and their relationship with the risk of ablation were analyzed in both groups. Results:There was no significant statistical difference in the immediate and short-term success rates between the two groups(93.8%vs.94.1%;90.6%vs.88.2%,both P>0.05).The experimental group did not receive contrast agents during the operation,and the total operation time and intra-aortic sinus operation time in the experimental group were significantly shorter than those in the conventional group([58.76±4.94]min vs.[66.91±5.94]min,P<0.001;[43.12±4.49]min vs.[50.31±5.18]min,P<0.001).During the process of moving the ablation catheter from the intra-aortic sinus to the coronary artery opening and into the coronary artery,the impedance suddenly increased,which was significantly different from the impedance in other parts of the intra-aortic sinus(all P<0.001). Conclusions:Radiofrequency ablation of ASC-PVC with zero X-ray can simplify the procedures and shorten the operative time.The steep increase in impedance at the tip of the ablation catheter can be used as a basis for localizing the coronary ostium.Dividing the aortic sinus into sections allows a detailed assessment of the risk for ablation treatment at the targets.

Moral resilience is the ability to positively respond to moral dilemmas,consisting of firm beliefs,tenacious willpower,harmonious relationships,and a peaceful mind.The Chinese nation is a resilient nation,its excellent traditional Chinese culture is vast and profound,containing extremely rich ideas about moral resilience.For example,"being erudite and determined,eager to ask and thinking closely,and benevolence lies in it"and"if one aspires to pursue benevolence,they will not do evil things".The ancients believed that human resilience could correct moral motives and enable people to overcome difficulties and forge ahead in adversity.The intellectual wisdom of the ancients can provide advice and consultation for cultivating moral resilience today.Therefore,need drawing on traditional culture to strengthen moral resilience.

Objective:To evaluate the role of volume management guided by extravascular lung water index(EVLWI) in improving the clinical outcomes and cardiac function for patients with cardiogenic shock.Methods:This study was a single-center, prospective cohort study. Patients with cardiogenic shock admitted to the Department of Cardiovascular Medicine, Shanghai East Hospital from July 2022 to December 2023 were enrolled. Patients were matched 1∶1 by propensity score and divided into EVLWI group and control group. In the control group, the volume management strategy was determined by the attending physician based mainly on conventional factors, including clinical features, biochemical assessments, and certain blood pressure measurements. In EVLWI group, the volume management plan was formulated by integrating conventional factors with EVLWI derived from pulse index continuous cardiac output (PiCCO) monitoring. Baseline clinical data, in-hospital treatment, and hemodynamic data were collected. Major adverse cardiovascular events and cardiac function related parameters were compared at 30 d after treatment between the two groups. Baseline EVLWI levels were compared between the non-survivors and the survivors in the EVLWI group. The receiver operating characteristic curve was plotted to assess the accuracy of baseline EVLWI and central venous pressure in predicting all-cause mortality at 30 d after treatment in patients with cardiogenic shock, and subgroup analysis was performed according to ischemic/non-ischemic etiology and with/without use of inotropic drugs. Kaplan-Meier curve was used for survival analysis, with log-rank tests comparing all-cause mortality, cardiac death, and readmission rate for heart failure at 30 d after treatment.Results:A total of 200 patients with cardiogenic shock were enrolled, aged (71.35±12.82) years, 144(72%) males, EVLWI group and control group 100 patients each. Compared with the control group, EVLWI group had lower all-cause mortality (16%(16/100) vs. 42%(42/100), log-rank P<0.01), cardiac death (14%(14/100) vs. 34%(34/100), log-rank P<0.01), and readmission rate for heart failure (4%(4/100) vs. 12%(12/100), log-rank P=0.03) at 30 d after treatment. Subgroup analysis showed that EVLWI-guided volume management was associated with lower all-cause mortality at 30 d after treatment in patients with cardiogenic shock of ischemic or non-ischemic etiology and with or without inotropic drugs (all P<0.05). In EVLWI group, baseline EVLWI levels were higher in non-survivors than those in survivors [(15.99±6.47) ml/kg vs.(9.75±2.55) ml/kg, P<0.01]. The baseline EVLWI could predicting all-cause mortality at 30 d after treatment in patients with cardiogenic shock, with an area under the receiver operating characteristic curve of 0.84 (95% CI: 0.75-0.94, P<0.01), while the baseline central venous pressure had no predicting value ( AUC=0.54, 95% CI: 0.40-0.69, P=0.60). The optimal cutoff value of EVLWI in pridicting all-cause mortality at 30 d after treatment in patients with cardiogenic shock was >10.3 ml/kg. With the optimization of hemodynamic parameters, left ventricular ejection fraction was improved in EVLWI group, and serum levels of N-terminal pro-brain natriuretic peptide, creatinine, alanine aminotransferase and lactic acid were decreased (all P<0.05). Conclusion:EVLWI-guided volume management exerts a beneficial effect on therapeutic decision-making and improves clinical outcomes and cardiac function in patients with cardiogenic shock.

The occurrence and development of malignant tumors are closely related to immune checkpoint receptors, and tumor cells can evade immune surveillance by activating the immune checkpoint pathway. T cell immunoglobulin and ITIM domain(TIGIT) is an inhibitory receptor expressed on lymphocytes, which can inhibit the function of natural killer cells(NK) and T cells through a variety of mechanisms, making tumor cells escape from the surveillance of the immune system. This article made a systematic review on the research progress of the immunosuppressive mechanism of TIGIT, and reviewed the research progress of the immunosuppressive mechanism of TIGIT.

It is believed that the basic pathogenesis of oculomotor nerve paralysis （ONP） is qi and blood depletion and channel obstruction. Taking channel pattern differentiation as the core， it is recommended to use acupuncture mainly based on location， syndrome and channel deficiency-excess differentiation. Location and channel tropism differentiation mainly follows the principle of “where the channels and collaterals pass， the main treatment can reach”， and commonly uses acupuncture points on Dumai （督脉）， the hand Shaoyang （少阳） Sanjiao （三焦） channel， the hand Taiyang （太阳） small intestine channel， three yang channels of the foot， the hand Shaoyin （少阴） heart channel， the foot Jueyin （厥阴） liver channel， and others， and combines scalp acupuncture with electro-acupuncture to enhance channel stimulation. Pattern and channel tropism differentiation is to differentiate the entered channel according to clinical symptoms and zang-fu patterns. The differentiation of deficiency-excess should be payed attention to， and the principle of “supplementing the deficiency， and draining the excess” should be followed. The supplementing and draining method should be used rationally by considering the differences in the supplementing and draining acupoints themselves， as well as the actual condition of the patients. Simultaneously， it is suggested to combine manipulation and stimulation amount and effect in clinical practice.

OBJECTIVE To s tudy the impr ovement effects of tilianin on the atherosclerosis （AS）model mice and its potential mechanism. METHODS Eight C 57BL/6J mice were taken as the normal group. Forty ApoE－/－ mice were randomly divided into model group ，tilianin low-dose ，medium-dose and high-dose groups [ 2.1，3.5，7.0 mg/（kg·d）] and simvastatin group [positive control drug ，3.5 mg/（kg·d）]，with 8 mice in each group. Normal group was given normal diet ，and other groups were given high-lipid diet to induce AS model. At the same time ，normal group and model group were given normal saline intragastrically ， administration groups were given relevant drug intragastrically ，once a day ，for 12 consecutive weeks. The levels of TC ，TG， LDL-C，HDL-C，Ox-LDL，IL-1β，IL-6，MCP-1 and TNF-α in plasma were determined. The pathomorphological changes of the aorta in mice were observed.

Lipid plaques were formed in the aorta ，and the plaque area was large and caused severe stenosis of the lumen. mRNA expressions of MMP- 2，MMP-9，TGF-β1，Smad2 and Smad 3 as well as positive rate of ICAM- 1，VCAM-1，PCNA and protein expression TGF-β1，Smad2/3，and p-Smad 2/3 in the aorta were significantly increased （P＜0.01）. Compared with model group ， most of above indexes of medication groups were improved significantly （P＜0.05 or P＜0.01）. CONCLUSIONS Tilianin can inhibit the activation of TGF-β1/Smads signaling pathway and then inhibit the proliferation of vascular smooth muscle cells ，reduce ， inflammation and regulate lipid metabolism to inhibit the No.81960766） formation of AS.

Objective:To investigate the distribution and antimicrobial resistance patterns of common pathogens in children with urinary tract infections in a single center in Shanghai, and to provide basis for the selection of empirical antibiotics in the clinical practice.Methods:The clinical data, urine culture and drug sensitivity tests results of children with urinary tract infections between 0 to 14 years admitted to the Children′s Hospital of Fudan University from January 2016 to December 2019 were retrospectively analyzed. According to the time of onset and the complicated factors, the patients were divided into different groups. The distributions and antimicrobial resistance patterns of common pathogens were compared among the groups. The chi-square test was used for statistical analysis.Results:Among the 1 832 children, 1 042 cases had positive urine culture, with the culture positive rate of 56.9%. The top five pathogens detected were Escherichia coli (375 strains, 36.0%), Enterococcus faecium (164 strains, 15.7%), Klebsiella pneumoniae (133 strains, 12.8%), Enterococcus faecalis (95 strains, 9.1%) and Pseudomonas aeruginosa (44 strains, 4.2%). The annual detection rates of gram-negative bacteria (65.3% to 72.9%) were always higher than those of gram-positive bacteria (22.6% to 30.1%). The distributions of pathogens among the years were not significantly different ( χ2 =27.79, P=0.146). In patients with complicated urinary tract infections, the detection rates of Pseudomonas aeruginosa (5.8%(40/688) vs 1.1%(4/354)) and fungi (6.5%(45/688) vs 1.7%(6/354)) were significantly higher than those in patients with simple urinary tract infections ( χ2=12.68 and 11.79, respectively, both P<0.050). Both of Escherichia coli and Klebsiella pneumoniae had the highest resistance rates to ampicillin, which were 87.2%(301/345) and 87.1%(115/132), respectively. The resistance rates of Escherichia coli to amikacin, nitrofurantoin, fosfomycin, cefmetazole, piperacillin/tazobactam, ertapenem, imipenem and meropenem were 1.4%(5/345), 6.1%(21/345), 6.1%(21/345), 8.3%(11/132), 11.6%(40/345), 6.4%(22/345), 4.6%(16/345) and 4.6%(16/345), respectively. The resistance rates of Klebsiella pneumoniae to these drugs were 6.1%(8/132), 37.9%(50/132), 15.2%(20/132), 23.2%(13/56), 26.5%(35/132), 23.5%(31/132), 17.4%(23/132) and 16.7%(22/132), respectively, which were all higher than those of Escherichia coli, and the differences were all statistically significant ( χ2=6.02, 76.17, 9.99, 7.94, 16.04, 28.29, 20.79 and 18.84, respectively, all P<0.050). The resistance rates of Pseudomonas aeruginosa to cefoperazone/sulbactam, piperacillin/tazobactam and ceftazidime were 6.8%(3/44), 4.5%(2/44) and 2.3%(1/44), respectively, while those to carbapenems, amikacin and ciprofloxacin were all 0(0/44). The resistance rate of Enterococcus faecium to ampicillin was 96.8%(153/158), while that of Enterococcus faecalis was 9.1%(8/88). There was no Enterococcus strain resistant to vancomycin, teicoplanin or linezolid. When dynamically comparing the trends of the antimicrobial resistance from 2016 to 2019, the resistance rates of Escherichia coli and Klebsiella pneumoniae to β-lactams (including carbapenems) antimicrobial agents had shown a downward trend. Conclusions:Gram-negative bacteria are still the main pathogens of urinary tract infections in children, with a downward trend of drug resistance rates to β-lactams (including carbapenems) antimicrobial agents.

OBJECTIVE：To s tudy the effects of Dracocephalum moldavica total flavonoids （TFDM）on AMPK/SIRT 1/PGC-1α signaling pathway ，and to explore the mechanism of its protective effect on myocardial ischemia reperfusion injury （MIRI）rats.
