Objective To compare the incidence of complications after removal of chest drainage tube in the early and late stages after sublobectomy for non-small cell lung cancer (NSCLC), and to analyze the factors affecting postoperative pleural drainage volume (PDV), so as to explore the countermeasures and achieve rapid postoperative rehabilitation. Methods The patients with NSCLC who underwent minimally invasive sublobectomy in our hospital from January to October 2021 were enrolled. According to the median time of extubation, the patients were divided into an early extubation group (time with tube≤3 days) and a late extubation group (time with tube>3 days). The patients were matched via propensity score matching with a ratio of 1:1 and a caliper value of 0.02. The incidence of complications and perioperative parameters after removal of the thoracic drainage tube were analyzed and compared between the two groups, and univariate and multiple linear regression analyses were performed. Results A total of 157 patients were enrolled, including 79 males and 78 females, with an average age of (58.22±11.06) years. There were 76 patients in the early extubation group, 81 patients in the late extubation group, and 56 patients were in each group after propensity score matching. Compared with late extubation group, there was no significant difference in the incidence of infection after extubation (10.7% vs. 16.1%, P=0.405) or pleural effusion after extubation (5.4% vs. 3.6%, P=0.647) in early extubation group, and there was no second operation in both groups. Univariate analysis showed that smoking history (P=0.001), postoperative serum albumin reduction value (P=0.017), surgical approach (P=0.014), lesion location (P=0.027), differentiation degree (P=0.041), TNM stage (P=0.043), number of dissected lymph nodes (P=0.016), and intraoperative blood loss (P=0.016) were infuencing factors for increased postoperative PDV. Multiple linear regression analysis showed that smoking history (P=0.002), postoperative serum albumin reduction value (P=0.041), and the number of dissected lymph nodes (P=0.023) were independent risk factors for increased postoperative PDV. Conclusion There is no significant difference in the incidence of complications after extubation between early and late extubations. Preoperative smoking history, excessive postoperative serum albumin decreases, and excessive number of dissected lymph nodes during the surgery are independent risk factors for increased postoperative PDV.

Objective To identify clinical risk factors for early major adverse cardiovascular events (MACEs) following surgical correction of supravalvar aortic stenosis (SVAS). Methods Patients who underwent SVAS surgical correction between 2002 and 2019 in Beijing and Yunnan Fuwai Cardiovascular Hospitals were included. The patients were divided into a MACEs group and a non-MACEs group based on whether MACEs concurring during postoperative hospitalization or within 30 days following surgical correction for SVAS. Their preoperative, intraoperative, and postoperative clinical data were collected for multivariate logistic regression. Results This study included 302 patients. There were 199 males and 103 females, with a median age of 63.0 (29.2, 131.2) months. The incidence of early postoperative MACEs was 7.0% (21/302). The multivariate logistic regression model identified independent risk factors for early postoperative MACEs, including ICU duration (OR=1.01, 95%CI 1.00-1.01, P=0.032), intraoperative cardiopulmonary bypass (CPB) time (OR=1.02, 95%CI 1.01-1.04, P=0.014), aortic annulus diameter (OR=0.65, 95%CI 0.43-0.97, P=0.035), aortic sinus inner diameter (OR=0.75, 95%CI 0.57-0.98, P=0.037), and diameter of the stenosis (OR=0.56, 95%CI 0.35-0.90, P=0.016). Conclusion The independent risk factors for early postoperative MACEs include ICU duration, intraoperative CPB time, aortic annulus diameter, aortic sinus inner diameter, and diameter of the stenosis. Early identification of high-risk populations for MACEs is beneficial for the development of clinical treatment strategies.

Objective To investigate the alleviation of Nippostrongylus brasiliensis infection on dextran sulfate sodium salt (DSS)-induced ulcerative colitis in mice, and to explore the underlying mechanism. Methods Thirty male C57BL/6J mice of the SPF grade, each weighing approximately 25 g, were randomly divided into three groups, including the blank control group (NC group), DSS modeling group (DSS group), and N. brasiliensis treatment group (Nb + DSS group), of 10 mice in each group. Mice in the DSS group were orally administered with 3.5% DSS daily since day 1 (D0) for 6 successive days, and given normal drinking water since D6, and animals in the Nb + DSS group were subcutaneously injected with the third-stage larvae of N. brasiliensis at a dose of 500 larvae per mice 5 days prior to D0, followed by oral administration with 3.5% DSS daily since D0 for 6 successive days and normal drinking water since D6, while mice in the NC group were given normal drinking water. Mouse body weight and stool were observed and the disease activity index (DAI) was scored in each group during the study period. All mice were sacrificed on D9. The mouse colon length was measured, and mouse colon specimens were subjected to hematoxylin-eosin (HE) staining and histopathological scoring. In addition, the mRNA and protein expression of interleukin (IL)-1β and IL-10 was quantified in mouse colon specimens using quantitative fluorescent real-time PCR (qPCR) assay and enzyme-linked immunosorbent assay (ELISA), and the mRNA and protein expression of mucosal repair-associated molecules zonula occludens-1 (ZO-1), mucin 2 (MUC2) and claudin-1 was detected in mouse colon specimens using qPCR assay and immunofluorescence assay. Results The mice body weights, DAI scores and colon lengths were (26.26 ± 1.93), (22.39 ± 1.65), (25.00 ± 1.58) g (F = 8.06, P < 0.01); (1.89 ± 0.34), (0.47 ± 0.39), 0 points (F = 57.61, P < 0.000 1); and (42.50 ± 5.75), (56.20 ± 5.96) mm and (61.17 ± 7.88) mm (F = 13.72, P < 0.001) in the NC, DSS and Nb + DSS groups on D9, respectively, and elevated mouse body weight (P < 0.05), reduced DAI score (P < 0.000 1) and increased colon length (P < 0.01) were observed in the Nb + DSS group relative to the DSS group on D9. Pathological examinations showed that the colonic crypts were relatively intact and the inflammatory cell infiltration was lower in the mouse colon specimens in the Nb + DSS group than in DSS the group. There was a significant difference in the histopathological scores of mouse colon specimens among the NC group (0 point), the DSS group [(2.00 ± 1.22) points] and the Nb + DSS group [(0.20 ± 0.45) points] (F = 10.71, P < 0.01), respectively, and the histopathological score of mouse colon specimens was significantly higher in the DSS group than in the NC and Nb + DSS groups (both P values < 0.01). qPCR assay quantified that the relative IL-10 and IL-1β mRNA expression was 1.25 ± 0.08, 0.44 ± 0.14 and 1.30 ± 0.45 (F = 10.66, P < 0.01), and 0.22 ± 0.13, 1.14 ± 0.31 and 0.41 ± 0.19 (F = 16.89, P < 0.001) in mouse colon specimens in the NC, DSS and Nb + DSS groups, respectively, and higher IL-10 mRNA expression and lower IL-1β mRNA expression were found in mouse colon specimens in the Nb + DSS group than in the DSS group (both P values < 0.01). The relative MUC2, claudin-1 and ZO-1 mRNA expression was 0.87 ± 0.25, 0.34 ± 0.26 and 4.21 ± 0.55 (F = 121.60, P < 0.000 1), 1.05 ± 0.41, 0.16 ± 0.09 and 0.22 ± 0.11 (F = 14.00, P < 0.01), and 1.03 ± 0.10, 0.60 ± 0.11 and 1.64 ± 0.28 (F = 32.16, P < 0.000 1) in mouse colon specimens in the NC, DSS and Nb + DSS groups, respectively, and significantly higher MUC2 and ZO-1 mRNA expression was quantified in mouse colon specimens in the Nb + DSS group than in the DSS group (both P values < 0.05). The mean fluorescence intensities of ZO-1 and claudin-1 were 17.18 ± 2.08, 12.38 ± 1.21 and 18.06 ± 2.59 (F = 8.95, P < 0.01) and 13.50 ± 1.63, 9.66 ± 2.03 and 13.61 ± 0.97 (F = 6.96, P < 0.05) in mouse colon specimens in the NC, DSS and Nb + DSS groups, respectively, and the mean fluorescence intensities of ZO-1 and claudin-1 were significantly greater in mouse colon specimens in the Nb + DSS group than in the DSS group (both P values < 0.05). Conclusion N. brasiliensis infection may remarkably alleviate DSS-induced ulcerative colitis in mice through promoting expression of anti-inflammatory cytokines, inhibiting expression of pro-inflammatory cytokines and facilitating mucosal repair in colon tissues.

Objective:To explore the chain mediating effects of anxiety/depression and metacognition between somatic symptoms and fear of disease progression (FoP) in gynecological tumor patients.Methods:A total of 208 gynecological tumor patients were investigated by general demographic data, fear of progression questionnaire-short form(FoP-Q-SF), hospital anxiety and depression scale(HADS), metacognition questionnaire(MCQ) and somatic symptom scale(SSS). SPSS 25.0 was used for Pearson correlation analysis. The significance of mediating effect was tested by deviation corrected nonparametric percentile Bootstrap method using SPSS macro program PROCESS.Results:The scores of FoP-Q-SF, depression, anxiety, MCQ and SSS were (32.41±10.43), (6.43±4.17), (7.51±4.10), (68.44±16.04), (20.58±15.70) respectively. 48.56% of gynecological tumor patients had dysfunctional fear of disease progression. Correlation analysis showed that FoP was significantly positively correlated with somatic symptoms ( r=0.394, P<0.01), anxiety ( r=0.640, P<0.01), depression ( r=0.533, P<0.01) and metacognition ( r=0.489, P<0.01). Mediating effect test showed that anxiety, depression and metacognition played a complete chain mediating role between somatic symptoms and FoP in gynecological tumor patients.The total effect of somatic symptoms on FoP was 0.320. Somatic symptoms indirectly affected FoP by influencing anxiety and metacognition, and the intermediary effect value was 0.242. Somatic symptoms indirectly affected FoP by influencing depression and metacognition, and the intermediary effect value was 0.212. Conclusion:Somatic symptoms can indirectly affect FoP through the chain mediation of anxiety/depression and metacognition.

Objective: To understand the association between positive and negative childhood experiences with uncertainty stress in college students. Methods: From March to May 2021, 1 816 college students in Jiangsu and Hubei Province were randomly selected, and an electronic structured questionnaire was used to collect the general characteristics, positive and adverse childhood experience, and uncertainty stress. Logistic regression was used to explore the association between positive and negative childhood experiences with uncertainty stress. Results: The reported rate of uncertainty stress among 1 816 college students was 27.5%( n =500). Logistic regression results showed that the risk of uncertainty stress among students with childhood abuse experience was 2.10 times higher than that of control group( OR=2.10, 95%CI =1.64-2.70). The probability of uncertainty stress in students with high self awareness was 37% of those with low self awareness( OR=0.37, 95%CI =0.24-0.57). The probability of uncertainty stress in students with positive predictable life was 32% of those without( OR=0.32, 95%CI =0.13-0.77). Conclusion College students are vulnerable population for psychological stress. Both positive and adverse childhood experience are associated with the occurrence of uncertainty stress. Early screening for with adverse childhood experiences in adolescents is recommended to protect physical and mental health.

Objective:To find out a specific group of patients undergoing in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) who can benefit from endometrial microstimulation (EM) and how to maximize the effect. Methods:A retrospective case-control study on 1916 cycles from women who underwent EM in Center for Reproductive Medicine, Shandong University between 2006 to 2018. Their baseline characteristics and cycle parameters were analyzed as well as the differences in EM procedures. Results:There were 1435 cycles from women ≤35 years old (867 succeeded in implantation and 568 failed) and 481 cycles from women >35 years old (179 succeeded in implantation and 302 failed). Among women ≤35 years old, compared with those who failed to implant, those who succeeded had thicker endometrium [(1.07±0.20) cm vs. (1.02±0.20) cm, OR=5.01, P<0.001] and a larger proportion of A/A- endometrial type (91.3% vs. 85.3%, OR=1.88, P=0.01) observed on trigger day. As for patients >35 years old, women who succeeded in implantation had thicker endometrium than those who failed in implantation [(1.05±0.19) cm vs. (0.96±0.22) cm, OR=8.73, P<0.001]. In addition, EM in luteal phase resulted in a significantly higher implantation rate in the >35 years old group compared with that when EM in follicular phase (42.9% vs. 32.7%, P=0.02). Conclusion:As for patients who were suggested to do the EM therapy, those ≤ 35 years old with better endometrium condition (thicker and A/A- endometrial type) or women >35 years old with thicker endometrium may benefit from EM, and EM in luteal phase increases implantation rates among >35-year-old patients compared with that when EM in follicular phase.

With the rapid development of tumor subjects and the advance of medical technology,tumor mortality is declining in spite of the increase in tumor incidence.The male survivors pay more and more attention to their prognosis to improve the quality of their life.In the meantime,whether they could produce their own offspring become the main concern of tumor patients with good prognosis.However,until now,male tumor patients,their relatives,different social sectors and even some of our health workers,havent noticed the importance of fertility preservation and long-term fertility desires of male patients with tumor which will lead to declined or even irreversible sterility induced by the lack of fertility preservation before anti-tumor therapy.It's an important way to do fertility counseling,learn the risk of their treatment plans and choose the appropriate technique of fertility preservation which will improve prognosis quality of life of male tumor patients.This article will review the effects of tumor and the treatment on male fertility,their subjective needs and concerns,main methods for fertility preservation and the domestic and foreign research present situation.

OBJECTIVE: To investigate the relationship between the eukaryotic initiation factor 3a (eIF3a)polymorphisms and chemo-sensitivity to platinum-based drug in ovarian cancer.
 METHODS: Matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) analysis was performed to detect 57 cases of eIF3a polymorphic genotypes (rs3824830, rs77382849, rs10787899 and rs3740556) after platinum-based chemotherapy drugs up to 6 cycles in primary ovarian cancer. The association between these gene sites was analyzed.
 RESULTS: There were 3 genotypes for eIF3a rs3824830, named AA, GA and GG. The frequency distribution for them was 43.86%, 36.84% and 15.79% (2 cases did not detect the genotype, 3.51%), respectively. There were 2 genotypes for eIF3a rs77382849, named CC and TC. The frequency distribution for them was 85.96% and 12.28%(1 case did not detect the genotype, 1.76%), respectively. There were 3 genotypes for eIF3a rs10787899, named GG, GA and AA, respectively. The frequency distribution for them was 26.32%, 47.36% and 26.32%, respectively. There were significant difference in different genotypes between age group and FIGO stage (P<0.05). The genotype of eIF3a rs10787899 GA was easier to resist platinum drug compared with the GG genotype and the odds ratio could be increased by 2.676 (95%CI: 0.544-13.159). The genotype of eIF3a rs10787899 AA was easier to resist platinum drug compared with the GG genotype and the odds ratio could be increased by 5.419(95%CI: 0.964-30.471). Rebalanced by age and FIGO stage, there was no significant difference (P>0.05) among these genotype groups. In all blood samples, there was only one genotype for eIF3a rs3740556, named GG.
 CONCLUSION There is no mutation genotype in eIF3a rs3740556 loci. Polymorphism in the eIF3a rs3824830, rs77382849 and rs10787899 doesn't affect the response of ovarian cancer to platinum-based chemotherapy.

BACKGROUNDDrug-eluting stents (DES) with durable polymer have significantly reduced restenosis and target vessel revascularization compared with bare metal stents. Durable polymer has been linked with persistent inflammation of vessel wall and delayed endothelial healing that may increase the risk of late and very late stent thrombosis. This study sought to evaluate the efficacy and safety of HELIOS completed biodegradable polymer sirolimus-eluting stent (SES) in de novo coronary lesions.

METHODSTotally, 287 patients with one or two de novo coronary lesions (lesion length ≤ 38 mm and reference vessel diameter 2.5-4.0 mm) were enrolled in the HOPE study, a prospective, multicenter, randomized, non-inferiority trial. Patients were randomized to treatment either with HELIOS completed biodegradable polymer SES (n = 142) or PARTNER durable polymer SES (n = 145). The primary endpoint was angiographic in-stent late lumen loss (LLL) at 9-month follow-up. The secondary endpoint included stent thrombosis and major adverse cardiac events including cardiac death, myocardial infarction (MI) and target lesion revascularization (TLR).

RESULTSThe 9-month in-stent LLL in the HELIOS group was similar to the PARTNER group, (0.16 ± 0.22) mm vs. (0.19 ± 0.30) mm (P = 0.28). The difference and 95% confidence interval were -0.03 (-0.09, 0.04), and the P value for non-inferiority <0.01. Major adverse cardiovascular event (MACE) occurred in 7.9% vs. 8.2%, MI in 2.4% vs. 3.0%, TLR in 5.5% vs. 3.0%, and stent thrombosis in 0 vs. 1.5%; and events were comparable between the HELIOS group and PARTNER group at three-year follow-up (all P > 0.05). The three-year cardiac death was lower in the HELIOS group, but with no significant difference, 0 vs. 3.0% (P = 0.12).

CONCLUSIONSIn the HOPE trial, the novel completed biodegradable polymer SES HELIOS was non-inferior to the durable polymer SES PARTNER with respect to nine-month in-stent LLL in de novo coronary lesions. The incidence of other clinical endpoints was low for both of the stents in three-year follow-up.
