Objective To explore the impact of contrast agent concentration on the excimer laser's effect on plaque ablation.Methods Using a laser catheter with a diameter of 0.9 mm,we conducted plaque model ablation experiments employing a 308-nanometer xenon chloride excimer laser.During the excimer laser ablation process,five groups were formed based on the injected contrast agent concentrations:a saline group,25%concentration group,50%concentration group,75%concentration group,and 100%concentration group.Optical coherence tomography was utilized to assess the changes in plaque lumen area after excimer laser ablation,evaluating the impact of contrast agent concentration on the excimer laser's ablation efficacy.Simultaneously,a water manometer was used to measure the shockwave pressure generated by the excimer laser in liquids with different contrast agent concentrations,aiming to explore the correlation between the shockwave pressure of the excimer laser and its ablative effect.Results The ablation areas in the 75%concentration group and the 100%concentration group were similar(P＞0.05),both exceeding those in the 50%concentration contrast agent group,25%concentration group,and saline group(all P＜0.001).Specifically,the ablation area in the 50%concentration group was significantly larger than that in the 25%concentration group and saline group(both P＜0.001),while the 25%concentration group was larger than the saline group(P＜0.001).The influence of contrast agent concentration on the shockwave pressure of the excimer laser exhibited a similar trend.Additionally,there was a significant positive correlation between the shockwave pressure generated by the excimer laser and its ablation area(r=0.9987,P＜0.001).Conclusions The intensity of excimer laser ablation on plaque tissue can be modulated by altering the contrast agent concentration.These findings offer guidance for the application of excimer laser in conjunction with contrast agent injection techniques in the treatment of coronary artery disease.

Objective: To study the incidence of bloodstream infections, pathogen distribution, and antibiotic resistance profile in patients with hematological malignancies. Methods: From January 2018 to December 2021, we retrospectively analyzed the clinical characteristics, pathogen distribution, and antibiotic resistance profiles of patients with malignant hematological diseases and bloodstream infections in the Department of Hematology, Nanfang Hospital, Southern Medical University. Results: A total of 582 incidences of bloodstream infections occurred in 22,717 inpatients. From 2018 to 2021, the incidence rates of bloodstream infections were 2.79%, 2.99%, 2.79%, and 2.02%, respectively. Five hundred ninety-nine types of bacteria were recovered from blood cultures, with 487 (81.3%) gram-negative bacteria, such as Klebsiella pneumonia, Escherichia coli, and Pseudomonas aeruginosa. Eighty-one (13.5%) were gram-positive bacteria, primarily Staphylococcus aureus, Staphylococcus epidermidis, and Enterococcus faecium, whereas the remaining 31 (5.2%) were fungi. Enterobacteriaceae resistance to carbapenems, piperacillin/tazobactam, cefoperazone sodium/sulbactam, and tigecycline were 11.0%, 15.3%, 15.4%, and 3.3%, with a descending trend year on year. Non-fermenters tolerated piperacillin/tazobactam, cefoperazone sodium/sulbactam, and quinolones at 29.6%, 13.3%, and 21.7%, respectively. However, only two gram-positive bacteria isolates were shown to be resistant to glycopeptide antibiotics. Conclusions: Bloodstream pathogens in hematological malignancies were broadly dispersed, most of which were gram-negative bacteria. Antibiotic resistance rates vary greatly between species. Our research serves as a valuable resource for the selection of empirical antibiotics.

Background: and Purpose Intravenous tenecteplase (TNK) efficacy has not been well demonstrated in acute ischemic stroke (AIS) beyond 4.5 hours after onset. This study aimed to determine the effect of intravenous TNK for AIS within 4.5 to 24 hours of onset. Methods: In this pilot trial, eligible AIS patients with diffusion-weighted imaging (DWI)-fluid attenuated inversion recovery (FLAIR) mismatch were randomly allocated to intravenous TNK (0.25 mg/kg) or standard care within 4.5–24 hours of onset. The primary endpoint was excellent functional outcome at 90 days (modified Rankin Scale [mRS] score of 0–1). The primary safety endpoint was symptomatic intracranial hemorrhage (sICH). Results: Of the randomly assigned 80 patients, the primary endpoint occurred in 52.5% (21/40) of TNK group and 50.0% (20/40) of control group, with no significant difference (unadjusted odds ratio, 1.11; 95% confidence interval 0.46–2.66; P=0.82). More early neurological improvement occurred in TNK group than in control group (11 vs. 3, P=0.03), but no significant differences were found in other secondary endpoints, such as mRS 0–2 at 90 days, shift analysis of mRS at 90 days, and change in National Institutes of Health Stroke Scale score at 24 hours and 7 days. There were no cases of sICH in this trial; however, asymptomatic intracranial hemorrhage occurred in 3 of the 40 patients (7.5%) in the TNK group. Conclusion This phase 2, randomized, multicenter study suggests that intravenous TNK within 4.5–24 hours of onset may be safe and feasible in AIS patients with a DWI-FLAIR mismatch.

OBJECTIVES: To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China. METHODS: A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups. RESULTS: Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05). CONCLUSIONS There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

Objective:To investigate the clinical efficacy of pancreaticoduodenectomy (PD) for periampullary diseases.Methods:The retrospective cohort study was conducted. The clinico-pathological data of 2 019 patients with periampullary diseases who underwent PD in the First Affiliated Hospital of Nanjing Medical University from January 2016 to December 2020 were collected. There were 1 193 males and 826 females, aged 63(15) years. Observation indicators: (1) surgical situations; (2) postoperative conditions; (3) postoperative pathological examinations; (4) prognosis of patients with periampullary carcinoma. Regular follow-up was conducted by telephone interview and outpatient examination once every 3 months within the postoperative first year and once every 6 months thereafter to detect the survival of patients with periampullary carcinoma. The follow-up was up to December 2021. Measurement data with skewed distribution were represented as M(IQR) or M(range), and comparison between groups was analyzed using the rank sum test. Count data were described as absolute numbers and (or) percentages, and comparison between groups was analyzed by the chi-square test or Fisher exact probability. Kaplan-Meier method was used to draw survival curves and calculate survival rates, and Log-Rank test was used to conduct survival analysis. Results:(1) Surgical situations: of 2 019 patients, 1 116 cases were admitted from 2016-2018 and 903 cases were admitted from 2019-2020.

There were 18 cases(0.892%) with carcinoma in other sites. Postoperative pathological examination showed carcinoma in 1 608 cases(79.643%), benign diseases or low potential malignancy in 411 cases(20.357%). The histological types of 1 608 patients with carcinoma included adenocarcinoma in 1 447 cases (89.988%), intra-ductal papillary mucinous carcinoma in 37 cases(2.301%), adenosquamous carcinoma in 35 cases(2.177%), adenocarcinoma with other cancerous components in 29 cases(1.803%), neuroendocrine carcinoma in 18 cases(1.119%), squamous carcinoma in 1 case (0.062%), and other histological malignancies in 41 cases(2.550%). The histological types of 411 patients with benign or low poten-tial malignancy included intraductal papillary mucinous neoplasm in 107 cases (26.034%), chronic or autoimmune inflammatory disease in 62 cases(15.085%), neuroendocrine tumor in 58 cases(14.112%), pancreatic serous cystadenoma in 52 cases(12.652%), pancreatic solid pseudopapillary tumor in 36 cases(8.759%), gastrointestinal stromal tumor in 29 cases(7.056%), villous ductal adenoma in 20 cases(4.866%), pancreatic mucinous cystadenoma in 2 cases(0.487%), pancreatic or duodenal trauma in 2 cases(0.487%) and other histological types in 43 cases(10.462%). (4) Prognosis of patients with periampullary carcinoma. Results of survival analysis of 1 590 patients with main locations of periampullary carcinoma showed that of 1 023 patients with pancreatic cancer, 969 cases were followed up for 3.0-69.6 months, with a median follow-up time of 30.9 months. The median overall survival time, 1-year, 3-year and 5-year survival rates of pancreatic cancer patients were 19.5 months [95% confidence interval ( CI) as 18.0-21.2 months], 74.28%, 29.22% and 17.92%. Of 225 patients with duodenal papillary cancer, 185 cases were followed up for 3.0-68.9 months, with a median follow-up time of 36.7 months. The median overall survival time, 1-year, 3-year and 5-year survival rates were unreached, 94.92%, 78.87% and 66.94%. Of 156 patients with distal bile duct cancer, 110 cases were followed up for 3.0-69.5 months, with a median follow-up time of 25.9 months. The median overall survival time, 1-year, 3-year and 5-year survival rates were 50.6 months (95% CI as 31.4 to not reached), 90.37%, 56.11% and 48.84%. Of 134 patients with ampullary cancer, 100 cases were followed up for 3.0-67.8 months, with a median follow-up time of 28.1 months. The median overall survival time, 1-year, 3-year and 5-year survival rates were 62.4 months (95% CI as 37.8 months to not reached), 90.57%, 64.98% and 62.22%. Of 52 patients with duodenal cancer, 38 cases were followed up for 3.0-69.5 months, with a median follow-up time of 26.2 months. The median overall survival time, 1-year, 3-year and 5-year survival rates were 52.0 months (95% CI as 30.6 months to not reached), 93.75%, 62.24% and 40.01%.There was a significant difference in overall survival after PD between patients with different locations of periampullary malignancies ( χ2=163.76, P<0.05). Conclusions:PD is safe and feasible in a high-volume pancreas center, but the incidence of overall postoperative complications remains high. With the increase of PD volume, the incidence of overall postoperative complications has significantly decreased. There is a significant difference in overall survival time after PD among patients with different locations of periampullary malignancies. The 5-year survival rate after PD for duodenal papillary cancer, ampullary cancer, duodenal cancer and distal bile duct cancer is relatively high, whereas for pancreatic cancer is low.

Objective:To assess the correlation between circulating chemerin and two indicators of renal function, estimated glomerular filtration rate (eGFR) and urine albumin creatinine ratio (UACR), in individuals with type 2 diabetes and to determine whether chemerin is an independent marker of early renal insufficiency.Methods:A total of 742 patients with type 2 diabetes were recruited into the cross-sectional community study. Basic information, anthropometric parameters, and biochemical parameters of these individuals were determined and collected, and serum chemerin level was measured using enzyme-linked immunosorbent assay.Results:Chemerin levels were significantly higher in the eGFR-impaired group compared with eGFR-normal group, and macroalbuminuria group compared to the normal or microalbuminuria groups. Spearman′ rank correlation analysis showed serum chemerin level was correlated with eGFR ( r=-0.25, P<0.001), UACR ( r=0.23, P<0.001) and some other biochemical indicators such as triglyceride. And univariate and multivariate logistic regression analyses revealed circulating chemerin was an independent risk factor for eGFR impairment or proteinuria after adjusting corresponding covariates. Receiver operating characteristic (ROC) curve analysis showed that the area under curve (AUC) of circulating chemerin for predicting early impaired eGFR in type 2 diabetes was 0.747, while the AUC of circulating chemerin for predicting macroalbuminuria in type 2 diabetes was 0.748. Conclusion:Circulating chemerin is associated with eGFR or UACR and may be a potential diagnostic marker for early renal insufficiency in type 2 diabetes.

OBJECTIVE: To investigate the consistency of cytomegalovirus deoxyribo nucleic acid (CMV-DNA) and immunoglobulin M (IgM) antibody detections in patients with different clinical characteristics and their guiding value for clinical practice. METHODS: From December 2014 to November 2019, a total of 507 patients who were detected with both CMV-IgM and CMV-DNA were collected in Peking University International Hospital. Their general information, such as gender, age and clinical data, including the patient's diagnosis, medication, and outcome were also collected. The groups were stratified according to whether CMV-DNA was negative or positive, CMV-IgM was negative or positive, age, gender, and whether they received immunosuppressive therapy or not. The Pearson Chi-square test or Fisher's exact test was used for comparison of the rates between the groups. P < 0.05 means the difference is statisti-cally significant. RESULTS: Of the 507 patients submitted for examination, 55 (10.85%) were positive for CMV-DNA, 74 (14.60%) were positive for CMV-IgM, and 20 (3.94%) were positive for both CMV-DNA and CMV-IgM. Of the 55 patients with CMV-DNA positive, 37 were male, accounting for 67.27%. In addition, 25 patients were older than 60 years, accounting for 45.45% and 33 patients received immunosuppressive therapy, accounting for 60%. The rates were higher than that of CMV-DNA negative group, 47.35% (P=0.005), 68.14% (P=0.043), 46.02% (P=0.050), respectively. Of the patients with both CMV-DNA and IgM positive, 45% received immunosuppressive threapy, which was lower than that of CMV-DNA positive but IgM negative patients (68.57%, P=0.086), and also lower than CMV-DNA negative but IgM positive patients (68.52%, P=0.064). In the patients with both CMV-DNA and IgM positive, 91.67% showed remission after receiving ganciclovir, whereas in the patients with CMV-DNA positive but IgM negative, the rate was only 60% (P=0.067). CONCLUSION CMV-IgM antibody detection is affected by age, gender, and immune status. It is not recommended to use CMV-IgM alone to determine CMV infection in patients with immunosuppressive status and those older than 60 years. CMV-DNA and CMV-IgM combined detection may help to predict patients' immune status and outcomes of antiviral therapy.
