Objective:To explore the prognostic value of epidermal growth factor receptor (EGFR) co-mutation status in patients with advanced lung adenocarcinoma.Methods:Clinical data of patients with stage ⅢB-Ⅳ lung adenocarcinoma who were first diagnosed in the Department of Respiratory and Critical Care Medicine, First Affiliated Hospital of Hebei North University from January 2019 to December 2022 were collected prospectively. Patients were divided into EGFR mutation group ( n=82) and EGFR co-mutation group ( n=74) according to whether EGFR was combined with other gene mutations. The level of circulating tumor DNA (ctDNA) in peripheral blood was measured by real time fluorescence quantitative PCR. Objective response rate (ORR), disease control rate (DCR), the levels of ctDNA in peripheral blood, and progression-free survival (PFS) were compared between two groups of patients before and after 1 month of treatment. The univariate and multivariate analyses were conducted by Cox proportional hazards regression model. Results:In the EGFR mutation group, there were 45 cases of EGFR19 deletion mutation and 37 cases of EGFR21 mutation. In the EGFR co-mutation group, there were 41 cases of EGFR19 deletion mutation, 33 cases of EGFR21 mutation, 46 cases of TP53 mutation, 16 cases of RB1 mutation, 6 cases of PTEN mutation, 2 cases of MET amplification, 1 case of ERBB2 mutation, 1 case of KRAS mutation, 1 case of RET rearrangement, and 1 case of ALK rearrangement. There were statistically significant differences between the EGFR mutation group and the EGFR co-mutation group in the maximum tumor diameter ( χ2=5.04, P=0.025) and stage ( χ2=3.92, P=0.048). The ORRs of the two groups were 64.63% (53/82) and 37.84% (28/74), respectively, with a statistically significant difference ( χ2=11.19, P<0.001). The DCRs were 96.34% (79/82) and 86.49% (64/74), respectively, with a statistically significant difference ( χ2=4.95, P=0.026). The ctDNA levels in the EGFR mutation group and EGFR co-mutation group after one month of treatment decreased compared to before treatment[2.63 (1.83, 3.30) ng/μl vs. 4.73 (3.92, 5.49) ng/μl, Z=-7.06, P<0.001; 4.26 (2.26, 6.07) ng/μl vs. 5.28 (4.37, 6.09) ng/μl, Z=-5.15, P<0.001], the ctDNA levels in the EGFR co-mutation group were higher than those in the EGFR mutation group before treatment and after 1 month of treatment ( Z=-2.47, P=0.013; Z=-4.29, P<0.001). In the EGFR co-mutation group, the ctDNA levels in peripheral blood of patients who were effectively treated with targeted therapy decreased after 1 month of treatment compared to before treatment [(2.03±0.63) ng/μl vs. (3.92±0.82) ng/μl, t=42.94, P<0.001], the levels of ctDNA in peripheral blood of ineffectively treated patients before and after 1 month of treatment were higher than those of effectively treated patients [(5.84±0.57) ng/μl vs. (3.92±0.82) ng/μl, t=-11.91, P<0.001; (5.87±1.64) ng/μl vs. (2.03±0.63) ng/μl, t=-14.43, P<0.001]. The median PFS of the EGFR mutation group and the EGFR co-mutation group of patients were 10.4 and 8.3 months, respectively, with a statistically significant difference ( χ2=22.28, P<0.001). Univariate analysis suggested that the maximum tumor diameter ( HR=0.10, 95% CI: 0.06-0.16, P<0.001), performance status (PS) score ( HR=0.09, 95% CI: 0.06-0.15, P<0.001), stage ( HR=0.09, 95% CI: 0.05-0.14, P<0.001), pre-treatment ctDNA level ( HR=12.04, 95% CI: 8.21-17.65, P<0.001), ctDNA level after 1 month of treatment ( HR=3.75, 95% CI: 3.10-4.54, P<0.001) and EGFR co-mutations ( HR=2.21, 95% CI: 1.57-3.12, P<0.001) were found to be significant factors affecting the PFS of stage ⅢB-Ⅳ lung adenocarcinoma patients receiving targeted therapy; Multivariate analysis demonstrated that PS score ( HR=0.25, 95% CI: 0.14-0.47, P<0.001), stage ( HR=0.49, 95% CI: 0.24-0.98, P=0.044), pre-treatment ctDNA level ( HR=4.73, 95% CI: 3.08-7.28, P<0.001), ctDNA level after 1 month of treatment ( HR=2.15, 95% CI: 1.65-2.80, P<0.001), and EGFR gene co-mutation ( HR=2.26, 95% CI: 1.40-3.64, P<0.001) were independent risk factors for PFS in stage ⅢB-Ⅳ lung adenocarcinoma patients receiving targeted therapy. Conclusion:Both the EGFR mutation group and EGFR co-mutation group show a decrease in ctDNA levels after targeted therapy for one month compared to before treatment. The median PFS of EGFR co-mutation patients is shorter than that of patients with a single EGFR mutation. PS score, stage, ctDNA levels before and after treatment, and EGFR gene co-mutation are all independent factors affecting PFS in stage ⅢB-Ⅳ lung adenocarcinoma patients after targeted therapy.

Objective:To investigate the correlation between blood pressure changes within 24 h after intravenous thrombolysis and the outcome in patients with acute ischemic stroke.Methods:Patients with acute ischemic stroke treated with alteplase intravenous thrombolysis in the Department of Neurology, Anhui No. 2 Provincial People's Hospital from June 2018 to September 2020 were enrolled retrospectively. The patients who received antihypertensive therapy before and within 24 h after intravenous thrombolysis were excluded. The blood pressure before intravenous thrombolysis and the blood pressure drop within 24 h after intravenous thrombolysis were recorded. The modified Rankin Scale was used to evaluate the clinical outcome at 90 d after the onset. 0-2 was defined as good outcome, and >2 was defined as poor outcome. Multivariate logistic regression analysis was used to investigate the independent correlation between blood pressure changes within 24 h after intravenous thrombolysis and the clinical outcomes. Results:A total of 205 patients with acute ischemic stroke were enrolled, including 125 males (60.98%), 80 females (39.02%); aged 63.30±9.63 years; 124 (60.49%) had a good outcome, and 81 (39.51%) had a poor outcome. Univariate analysis showed that the proportion of diabetic patients as well as baseline systolic blood pressure, prethrombolytic blood glucose, baseline National Institutes of Health Stroke Scale score, and the incidence of symptomatic intracranial hemorrhage in the good outcome group were significantly lower than those in the poor outcome group, and the proportion of patients with small vessel occlusion and the decrease in systolic blood pressure within 24 h after thrombolytic therapy were significantly higher than those in the poor outcome group (all P<0.05). Multivariate logistic regression analysis showed that higher baseline systolic blood pressure was independently associated with the poor outcome at 90 d after intravenous thrombolysis (odds ratio 0.964, 95% confidence interval 0.942-0.987; P=0.002), and a greater decrease in systolic blood pressure within 24 h after intravenous thrombolysis was independently associated with a good outcome (odds ratio 1.134, 95% confidence interval 1.067-1.206; P<0.001). Conclusion:For patients with acute ischemic stroke who received intravenous thrombolysis, higher baseline blood pressure before intravenous thrombolysis was associated with the poor outcome, and greater decrease in systolic blood pressure within 24 h after intravenous thrombolysis was associated with the good outcome.

Objective:To compare the expression levels of absent in melanoma 2 (AIM2) inflammasome pathways in rheumatoid arthritis (RA) and osteoarthritis (OA) synovial specimens.Methods:Synovial tissue samples were collected from 41 RA and 26 OA patients, respectively. Horseradish peroxidase immunohi stochemical staining was used to detect AIM2 inflammasome pathway-related proteins, including AIM2, apoptosis-associated speck-like protein containing a CARD(ASC), caspase-1, and interleukin-1 (IL-1β). A semi-quantitative score (H-score) was performed according to the degree of positiveness. Correlation analysis between H-score results and clinical indicators of erythrocyte sedimentation tate (ESR) and C-reactive protein (CRP) were performed. The H score between RA and OA was analyzed by t test and Spearman correlation analysis were utilized for correlation analysis between H score and ESR and CRP.Results:The H scores of AIM2 protein in RA synovial tissues was (132±7) and (54±8) in OA synovial tissues ( t=7.42, P<0.01). The H scores of ASC protein in RA synovial tissues was (107±9) and (74±6) in OA synovial tissues ( t=2.36, P<0.05). The H scores of caspase-1 protein in RA synovial tissues was (99±5) and (74±10) in OA synovial tissues ( t=2.15, P<0.05). The H scores of IL-1β protein in RA synovial tissues was (118±11) and (76±7) in OA synovial tissues ( t=3.30, P<0.05) . In the correlation analysis, AIM2 was positively correlated with ESR [ r=0.74, P<0.01, 95% CI(0.38, 0.9)], and ASC was positively correlated with ESR [ r=0.5, P<0.05, 95% CI(0.16, 0.74)], IL-1β was positively correlated with ESR [ r=0.62, P<0.05, 95% CI (0.31, 0.81)], and the difference was statistically significant ( P<0.05). At the same time, AIM2 was positively correlated with CRP [ r=0.65, P<0.05, 95% CI(0.25, 0.86)]; ACS was positively correlated with CRP [ r=0.42, P<0.05, 95% CI(0.05, 0.69)]. IL-1β was positively correlated with C-reactive Protein [ r=0.41, P<0.05, 95% CI(0.05, 0.67)] and positively correlated with C-reactive protein, and the difference was statistically significant ( P<0.05). Conclusion::The expression of AIM2 inflammasome pathway-related proteins in RA synovium, including AIM2, ASC, caspase-1, and IL-1β, is higher than that of OA and are positively correlated with disease activity. Activation of AIM2 inflammasome pathway may be associated with the pathogenesis of RA disease activity.

Objective To evaluate endoscopic surgical treatment of synchronous esophageal squamous cell carcinoma and adenocarcinonm at the esophagogastric junction.Methods The clinical data of 17 patients with synchronous esophageal squamous cell carcinoma associated with adenocarcinoma of esophagogatric junction between Jan 2010 and Jan 2017 were analyzed retrospectively.Results Among these 17 patients,9 patients underwent thoracoscopy and laparoscopy with partial resection of esophagus and proximal stomach,and gastroesophageal and neck anastomosis.3 patients underwent thoracoscopy and laparoscopy with partial resection of esophagus and proximal stomach,gastroesophageal intrathoracic anastomosis.Laparoscopic radical total gastrectomy combined with radiotherapy for esophageal cancer was performed in 5 cases.There was not perioperative death or serious complications.The cumulative survival rates of 1,3 and 5 years after surgery were 100％,42％ and 24％,respectively.Conclusion Thoracolaparscopic surgery combined with local radiation therapy is a safe and effective treatment for patients with synchronous esophageal squamous cell carcinoma and adenocarcinoma at esophagogastric junction.

Objective To compare the efficacy and safety of low-dose and standard-dose alteplase intravenous thrombolytic therapy in patients with acute ischemic stroke and to investigate whether low-dose alteplase is more suitable for patients with acute ischemic stroke in China.Methods Patients with acute ischemic stroke treated with alteplase intravenous thrombolysis from July 2016 to December 2018 in Anhui No.2 Provincial People's Hospital were enrolled retrospectively.According to the dose of alteplase,they were divided into low-dose group (0.6 mg/kg,the total dose not exceeding 60 mg) and standard dose group (0.9 mg/kg,the total dose not exceeding 90 mg).The efficacy endpoint was the clinical outcome at 90 d after onset evaluated by the modified Rankin Scale (mRS).The mRS score 0-2 was defined as self-care in life,and 0-1 was defined as good outcome.The safety endpoints were the incidence of symptomatic intracerebral hemorrhage (sICH) within 24-48 h after thrombolytic therapy and the mortality at 3 months.Results A total of 103 patients were enrolled,including 45 in the low-dose group and 58 in the standard dose group.There were no significant differences in demography,baseline clinical data,as well as self-care and good outcome rates at 90 d between the 2 groups.The incidence of sICH in the low-dose group (National Institute of Neurological Disorders and Stroke criteria:2.22％ vs.17.24％;x2 =4.521,P=0.033) and mortality at 90 d (6.67％ vs.24.14％;x2 =4.417,P =0.036) were significantly lower than those in the standard dose group.Conclusion The efficacy of low-dose alteplase in the treatment of acute ischemic stroke was comparable to that of standard dose,but the incidence of sICH and mortality at 90 d were significantly reduced,which might be more suitable for Chinese patients.

Some new types of microemulsion using phospholipids as the main surfactant were prepared for electrokinetic chromatography and the quantitative structure-retention relationship of neutral solutes in these microemulsion electrokinetic chromatography (MEEKC) systems was studied by solvation parameters model.By using dynamic coating capillary, and with dimethyl sulfoxide (DMSO) and dodecyl benzene as the marker of electroosmotic flow and microemulsion droplets, a total of 17 kinds of stable microemulsions containing soybean phospholipids or other surfactants were prepared and the linear salvation energy relationship equations were developed for these MEEKC systems with 26 small neutral compounds.The coefficients of linear solvation energy relationship (LSER) equations were used to evaluate the similarity of two MEEKC systems.Results indicated that LSER characteristics of phospholipids-MEEKC systems were similar to those of other microemulsion systems.The volume and hydrogen bond basicity of solutes were mostly contributed to the retention in MEEKC.The different types and concentration of oil phase had no evident influence on the retention.
