The current research status and hotspots were mainly the application and therapeutic exploration of new thrombolytic drugs， and the frontier and development trend were the adverse prognosis of neurological deterioration and hemorrhagic transformation accompanied by intravenous thrombolytic drug treatment. CONCLUSIONS The research hotspots and frontier about intravenous thrombolytic drugs for acute ischemic stroke are mainly the third generation of intravenous tissue plasminogen activator， and the exploration of new intravenous thrombolytic drugs and their safety and effectiveness will be the future research hotspots. Chinese scholars and research teams should strengthen cooperation and exchanges with other countries， which can be strengthened by carrying out multi-center clinical trials.

Objective To compare the accuracy of bedside lung ultrasound in emergency(BLUE)and combined cardiac-lung and additional ultrasound(CLAUS)for diagnosing the causes of acute dyspnea.Methods Totally 1 016 patients with acute dyspnea were retrospectively enrolled and divided into cardiogenic pulmonary edema group(n=268),pneumonia group(n=574),pneumothorax group(n=33),pulmonary embolism group(n=67)and CAD(chronic obstructive pulmonary disease/asthma/diaphragmatic dysfunction)group(n=74)according to the causes of acute dyspnea.The findings of CLAUS protocol were compared among groups,and the accuracy of BLUE and CLAUS protocol for diagnosing the causes of acute dyspnea were also compared.Results CLAUS showed that B-B and B-C were the most common modes in cardiogenic pulmonary edema group,while A-B/A-C/B-A/B-B/B-C/C-C modes were common in pneumonia group,and A-A mode was the most common in pneumothorax group,pulmonary embolism group and CAD group.Significant differences of the manifestations of pulmonary ultrasound,pleural feature of anterior chest wall,left/right cardiac insufficiency and abnormal inferior vena cava diameter were found among groups(all P＜0.05).The accuracy of BLUE and CLAUS protocol for diagnosing the causes of acute dyspnea was 86.91%(883/1 016)and 94.49%(960/1 016),respectively,the latter was higher than the former(χ2=34.587,P＜0.05).Conclusion CLAUS protocol could be used to effectively diagnose the causes of acute dyspnea,with higher accuracy than BLUE protocol.

Objective:To investigate the independent and combined effects of maternal smoking during pregnancy and offspring genetic susceptibility on overall cancer mortality.Methods:Based on the United Kingdom Biobank ( n=419 228) data, the Cox proportional hazard regression model was used to estimate the effect of maternal smoking during pregnancy on offspring overall cancer (including 16 cancers in men and 18 in women) mortality and its combined effect and interaction with offspring genetic factors. Results:Maternal smoking during pregnancy was significantly associated with a 13% increased risk of overall cancer mortality in men [hazard ratio( HR)=1.13, 95% CI: 1.06-1.20] and 19% increased risk in women ( HR=1.19, 95% CI: 1.11-1.27). Participants with high genetic risk had the highest overall cancer mortality than those with low genetic risk (men: HR=1.42, 95% CI: 1.30-1.55; women: HR=1.38, 95% CI: 1.25-1.52). Compared with participants without maternal smoking during pregnancy and low genetic risk, those with maternal smoking during pregnancy and high genetic risk were associated with a 56% increased risk of overall cancer mortality in men ( HR=1.56, 95% CI: 1.37-1.77) and 59% in women ( HR=1.59, 95% CI: 1.39-1.83). Conclusion:Maternal smoking during pregnancy may increase offspring overall cancer mortality and more severe harm in individuals with high genetic risk.

Approximately 30%-40% of prostate cancer patients undergoing surgical treatment will experience biochemical recurrence. However, this proportion will be increased to 50%-70% among those with locally advanced, high-risk disease. In contrast to the approach of active surveillance, adjuvant radiotherapy (ART) administered after prostate surgery has demonstrated a substantial reduction of approximately 50% in the risk of biochemical recurrence among high-risk patients exhibiting adverse pathological characteristics such as extraprostatic extension, seminal vesicle invasion, a high Gleason score, or positive surgical margins. This conclusion is firmly supported by the results of three prior randomized controlled trials. In three recently published comparative studies, salvage radiation therapy (SRT) and ART were rigorously compared among patients with high-risk prostate cancer who had undergone surgical treatment. The results revealed that the early SRT cohort exhibited comparable rates of event-free survival, clinical outcomes, and radiological progression to those observed in the ART group. Notably, the SRT group reported significantly fewer adverse effects related to urinary and bowel functions, suggesting a more favorable safety profile compared to the ART group. However, there is substantial heterogeneity among the enrolled patient populations across these studies, exhibiting unfavorable characteristics. In real-world settings, we frequently encounter patients with multiple high-risk characteristics and those who have developed pelvic lymph node metastasis postoperatively. Given this, it is imperative to undertake an individualized analysis of these adverse features, which will enable us to precisely identify patients who are most responsive to postoperative ART while effectively mitigating radiotherapy-related adverse effects. Consequently, an improvement can be obtained in patient survival rates while also ensuring their quality of life.

Aim To study the effect of liraglutide on myocardial metabolites and related metabolic pathways in diabetic cardiomyopathy(DCM)rats.Methods Among 60 SPF male SD rats aged 3 weeks,10 rats were randomly selected as normal control group(n=10),and the remaining 50 rats were established by peritoneal injection of streptozoto-cin combined with high-sugar and high-fat diet for DCM rat model.A total of 36 rats were successfully modeled for DCM and randomly divided into DCM model group(DCM group,n=12),low-dose liraglutide treatment group(LL group,n=12)and high-dose liraglutide treatment group(HL group,n=12).Rats in LL group(100 μg/kg)and HL group(200μg/kg)were given intraperitoneal injection of liraglutide once a day.And after 12 weeks of intervention,the rats were killed under anesthesia after echocardiography to detect cardiac function,and the heart tissues were taken for metabolomics detection.The differential metabolites and related pathways that may be related to liraglutide improving myocardial metab-olism in DCM rats were screened and enriched.Results Compared with normal control group,left ventricular ejection fraction(LVEF)and left ventricular fractional shortening(LVFS)in DCM group were significantly decreased,and the ra-tio of early to late diastolic mitralflow velocities(E/A)was significantly increased(P＜0.05).Compared with DCM group,LVEF and LVFS in LL group and HL group were significantly increased,and E/A ratio was significantly decreased(P＜0.05),suggesting that the impairment of left ventricular systolic and diastolic function in LL group and HL group was significantly alleviated.395 metabolites were detected by metabolomics,among which 239,116 and 187 different metab-olites and 13,6 and 20 metabolic pathways were enriched in DCM group and normal control group,LL group and DCM group,HL group and DCM group.In the above three groups,29 key differential metabolites were identified related to 3 metabolic pathways including choline metabolic pathway,caffeine metabolic pathway and valine,leucine and isoleucine bi-osynthesis pathway,among which choline metabolic pathway had the most significant differences.Conclusion These results indicated that liraglutide can ameliorate cardiac dysfunction in DCM rats through improving myocardial metabolism in which choline metabolism pathway may play a key role.

Objective To compare the safety,effectiveness and affordability of robotic-assisted thoracic surgery and video-assisted thoracic surgery in the treatment of malignant pulmonary tumors,and provide ref-erences for the management of selection of different surgical strategies for malignant pulmonary tumors in hospitals and medical insurance departments.Methods The medical records homepages and information sys-tem data of patients with malignant pulmonary tumors who underwent major thoracic surgery in this hospital and discharged from January 1 to December 31,2022 were obtained.The patients were divided into the robotic-assistedthoracic surgery group and video-assisted thoracic surgery group according to the surgical methodolo-gies.After performing propensity score matching (PSM),no statistically significant difference was observed in baseline data between the two groups (117 cases in each group).Then the indicators of safety,effectiveness and affordability were compared between the two groups.Results Concerning the safety,the postoperative in-cision infection rate in the robotic-assisted thoracic surgery group was significantly lower than that in the vide-o-assisted thoracic surgery group (P<0.05),and the amount of intraoperative blood loss and postoperative complication rate were not significantly different between the two groups (P>0.05).Regarding the effective-ness,the average surgical duration in the robotic-assisted thoracic surgery group was appreciably shorter than that in the video-assisted thoracic surgery group (P<0.05),no patient in the two groups was converted to open thoracotomy,and there was no statistically significant difference in the average length of hospital stay and postoperative hospital stay between the two groups (P>0.05).With regard to the affordability,the aver-age inpatient expenditure per case and average daily inpatient expenditure per case in the robotic-assisted tho-racic surgery group were significantly higher than those in the video-assisted thoracic surgery group (P<0.05),and there were disparities in the cost structure between the two procedures.The medical cost,adminis-tration cost and consumables cost in the robotic-assisted thoracic surgery group were significantly higher than those in the video-assisted thoracic surgery group (P<0.05).The cost of medical technology in the robotic-assisted thoracic surgery group was significantly lower than that in the video-assisted thoracic surgery group (P<0.05).Conclusion Physicians should comprehensively consider the clinical efficacy and cost burden of patients when selecting the robotic-assisted thoracic surgery or the video-assisted thoracic surgery,and the monitoring and evaluation of the utilization of clinical robotic-assisted thoracic surgery should be strength-ened.

Objective To explore the clinical efficacy of escitalopram combined with multidisciplinary collaborative management model(MCMM)on adolescents with first-episode major depressive disorder(MDD).Methods Two hundred adolescents with first-episode MDD who admitted to Fuyang Third People's Hospital,Anhui Province,from January 2019 to November 2023,were selected as study participnts.They were randomly divided into a control group and a MCMM group.Both groups of patients received sertraline hydrochloride tablets and routine psychiatric care for 8 weeks.Additionally,the MCMM group received an MCMM intervention on this basis.The clinical efficacy of the interventions,pre-and post-treatment assessments included clinical scale data[Hamilton Depression Scale(HAMD),Hamilton Anxiety Scale(HAMA),and Connor-Davidson Resilience Scale(CD-RISC)],inflammatory factors[interleukin-1β(IL-1β),interleukin-6(IL-6),and tumor necrosis factor-α(TNF-α)],neurotrophin factors[serotonin(5-hydroxytryptamine,5-HT)and glial cell-derived neurotrophic factor(GDNF)]were compared between the two groups.Results Before the intervention,there were no statistical differences in the clinical scale data,inflammatory factors and neurotrophic factors between the two groups(P＞0.05).After 8 weeks of intervention,the HAMD score,HAMA score,serum IL-1β,IL-6,TNF-α,5-HT,and GDNF levels significantly decreased compared with pre-intervention(P＜0.05),while the CD-RISC score significantly increased(P＜0.05).In addition,the MCMM group showed greater reductions in HAMD,HAMA,IL-1β,IL-6,TNF-α,5-HT,and GDNF levels and a greater increase in CD-RISC score compared to the control group(P＜0.05).Conclusion Compared with sertraline combined with routine care,MCMM significantly alleviates anxiety and depression,enhances psychological resilience,and reduces inflammation in MDD patients.

Objective To explore the value of tissue Doppler imaging(TDI)corrected diaphragm ultrasonic parameters for evaluating diaphragmatic function in dyspnea patients who underwent non-invasive mechanical ventilation.Methods Thirty-one acute dyspnea patients who underwent non-invasive mechanical ventilation less than 1 h(non-invasive ventilation group)and 31 healthy subjects(control group)were prospectively enrolled,and ultrasound of diaphragm was performed.Routine diaphragmatic parameters,including diaphragm displacement(DD),diaphragm thickness of end-expiratory(DTee),diaphragm thickness of end-inspiratory(DTei)and diaphragm thickening fraction(DTF)were measured and calculated,while peak systolic velocity of diaphragm(DPSV)and peak diastolic velocity of diaphragm(DPDV)were measured using TDI mode.Based on DD and DTF after rapid shallow breathing index(RSBI),DD-RSBI and DTF-RSBI were corrected,DPSV-RSBI and DPDV-RSBI were obtained by calculating product of DPSV and DPDV with respiratory rate,respectively.The index of compensatory work of diaphragm during systole(DD/DPSV and DTF/DPSV)and diastole(DD/DPDV and DTF/DPDV)were obtained by corrected DD and DTF with DPSV and DPDV,respectively.The ultrasonic parameters of diaphragm were compared between groups.Receiver operating characteristic(ROC)curve was drawn,and the area under the curve(AUC)was calculated to evaluate the efficacy of ultrasonic parameters of diaphragm for assessing diaphragmatic function in dyspnea patients who underwent non-invasive mechanical ventilation.Results DPSV,DPDV,DD-RSBI,DTF-RSBI,DPSV-RSBI and DPDV-RSBI in non-invasive ventilation group were all higher,while DD/DPSV,DD/DPDV,DTF/DPSV and DTF/DPDV were all lower than those in control group(all P＜0.05).No significant difference of DD,DTee,DTei nor DTF was found between groups(all P＞0.05).DPSV-RSBI and DPDV-RSBI had excellent efficacy for assessing diaphragmatic function in dyspnea patients after non-invasive mechanical ventilation(AUC=0.974,0.919),DPSV,DD-RSBI,DTF-RSBI,DD/DPSV and DTF/DPSV had good efficacy(AUC 0.760-0.881),while DD,DPDV,DTee,DTei,DTF,DD/DPDV and DTF/DPDV had bad or general efficacy(AUC 0.467-0.698).Conclusion TDI corrected diaphragm ultrasonic parameters could effectively evaluate diaphragmatic function in dyspnea patients who underwent non-invasive mechanical ventilation.

OBJECTIVE: To investigate the effect of vitamin D binding protein (DBP) gene polymorphism on susceptibility and prognosis of severe acute pancreatitis (SAP). METHODS: A prospective study was conducted. Eighty-three patients with SAP who were admitted to the department of general surgery of Tianjin Fifth Central Hospital from March 2018 to March 2021 were selected as the research objects, and 83 healthy people in the same period were selected as controls. Peripheral blood RNA was extracted and reverse transcribed into cDNA, and the genotype and allele frequency of DBP gene rs7041 locus were detected by fluorescence quantitative analyzer. Hardy-Weinberg equilibrium was used to test the genetic balance. On the day of admission, serum C-reactive protein (CRP) level was detected by scattering immunoturbidimetry, serum procalcitonin (PCT) level was detected by electrochemiluminescence, serum DBP level was detected by enzyme-linked immunosorbent assay (ELISA), and neutrophil to lymphocyte ratio (NLR) was calculated automatically by the instrument. The length of intensive care unit (ICU) stay, the length of hospital stay and prognosis during hospitalization of patients were statistically analyzed. Multivariate Logistic regression analysis was used to screen the influencing factors of SAP occurrence. RESULTS: The results of Hardy-Weinberg equilibrium test showed that the distribution of gene polymorphisms in the two groups of subjects conformed to the law of genetic equilibrium. The frequencies of TT genotype and T allele of DBP gene rs7041 locus in the patients of SAP group were significantly higher than those in the healthy control group [TT genotype: 34.94% (29/83) vs. 9.64% (8/83), T allele: 55.42% (92/166) vs. 38.55% (64/166), both P < 0.01], and the frequency of GT genotype was significantly lower than that in the healthy control group [40.96% (34/83) vs. 57.83% (48/83), P < 0.05]. There was no significant difference in the frequency of GG genotype between the healthy control group and SAP group [32.53% (27/83) vs. 24.10% (20/83), P > 0.05]. Further multivariate Logistic regression analysis showed that TT genotype [odds ratio (OR) = 2.831, 95% confidence interval (95%CI) was 1.582-5.067, P < 0.001] and T allele (OR = 2.533, 95%CI was 1.435-4.472, P < 0.001) of DBP gene rs7041 locus were independent risk factors for SAP in healthy people, while GT genotype was a protective factor for SAP (OR = 0.353, 95%CI was 0.143-0.868, P = 0.041). The levels of CRP, PCT, NLR and DBP in patients with TT genotype of DBP gene rs7041 locus were significantly higher than those in patients with GG/GT genotype on the day of admission in SAP group [CRP (mg/L): 43.25±13.25 vs. 31.86±12.83, PCT (μg/L): 1.53±0.24 vs. 1.21±0.20, NLR: 3.15±0.53 vs. 2.71±0.48, DBP (μg/L): 87.78±19.64 vs. 70.58±18.67, all P < 0.01]. The length of ICU stay in patients with TT genotype of DBP gene rs7041 locus in SAP group was significantly longer than that in patients with GG/GT genotype (days: 11.35±1.58 vs. 9.71±1.35, P < 0.01). The length of hospital stay of patients with TT genotype was longer than that of patients with GG/GT genotype (days: 23.41±3.64 vs. 23.17±3.57), and the in-hospital mortality was higher than that of patients with GG/GT genotype [34.48% (10/29) vs. 29.63% (16/54)], but the difference was not statistically significant (both P > 0.05). CONCLUSIONS The risk of SAP was significantly increased in patients with TT genotype of rs7041 locus of DBP gene, and the mechanism may be related to the increase of DBP expression. And carrying the TT genotype will prolong the ICU hospitalization time of SAP patients, but the effect on prognosis is not obvious.
