ABSTRACT

Aim To investigate the inhibitory effect of kappa-opioid receptor(κ-OR)stimulation on extracellular signal-regulated kinase pathway on ET-1-induced cardiomyocyte hypertrophy in vitro cultured myocardial cells from neonatal rats.Methods Myocardial cells of neonatal rats were cultured in vitro.The hypertrophic myocytes were induced by ET-1(10 nmol·L-1)before κ-OR agonist U50488H(1 μmol·L-1)was administered.The antihypertrophic effect of κ-OR stimulation was observed in the presence of U0126(1μmol·L-1), Ro-31-8220(50 nmol·L-1)and PTX(5 mg·L-1).The cardiomyocytes volume was measured by computer photographalysis system.The relative expression of ERK1/2 was determined by Western blot.The morphological changes in cardiomyocytes were observed under an inverted phase contrast microscope.The expression of mRNA of atrial natriuretic peptide(ANP)was determined by RT-PCR.Results Compared with normal control group, ET-1 could induced cardiomyocyte hypertrophy.Compared with ET-1 model group, U50488H(1 μmol·L-1)could obviously inhibit ET-1-induced increase of the cardiomyocytes volume, expression of ANPmRNA and expression of ERK1/2, which was similar to U0126(1 μmol·L-1)and Ro-31-8220(50 nmol·L-1); however, the inhibitory effects of U50488H were partly lost when preincubated with U0126(1 μmol·L-1)and Ro-31-8220(50 nmol·L-1); the inhibitory effects of U50488H, U0126(1 μmol·L-1)and Ro-31-8220(50 nmol·L-1)were lost when preincubated with NOR-BNI.Conclusion The stimulation of kappa-opiod can inhibit myocardial hypertrophy induced by ET-1, which is possibly via attenuating ERK1/2.

ABSTRACT

ObjectiveTo assess the effects of non-occupational mixed exposure to cadmium, lead and perfluoroalkyl substances (PFASs) on thyroid hormones (TH) in healthy adult residents in Shanghai. MethodsIn November 2018, adults in Shanghai Suburban Adult Cohort and Biobank study, who visited a community health service center for examination with no history of occupational exposure, thyroid diseases or chronic diseases, were recruited. A social-demographic information questionnaire survey was conducted and urine and blood samples were collected. Inductively coupled plasma mass spectrometry (ICP-MS) was used to measure their urinary cadmium (UCd), blood cadmium (BCd) and blood lead (BPb) concentrations. Ultra-high performance liquid chromatography-quadrupole time-of-flight tandem mass spectrometry (UPLC-Q/TOF MS) was used to measure 11 kinds of PFASs. Total and free triiodothyronine (TT3, FT3), total and free thyroxine (TT4, FT4) and thyroid simulating hormones were measured by chemiluminescence enzyme-linked immunoassay. 436 participants were finally included and LASSO regression, multivariate regression and weighted quantile sum regression were used to evaluate the associations of these environmental pollutants with thyroid hormones. ResultsAmong the participants, 185 were male (42.5%) and the median age was 60 (P25‒P75: 50‒66). The detection rates of urinary cadmium, blood cadmium and blood lead were all more than 95% and the detection rates of 7 PFASs (PFOS, PFOA, PFHxS, PFUnDA, PFNA, PFD, and PFBS) were more than 90%. The median exposure level of PFOA was the highest (49.6 µg‧L-1) among PFASs, followed by PFHxS (22.8 µg‧L-1) and PFOS (15.4 µg‧L-1), and the median exposure levels of urinary cadmium, blood cadmium and blood lead were 0.7 μg‧g-1(Corrected for creatinine of urine), 0.8 µg‧L-1, and 15.4 µg‧L-1, respectively. The results showed that UCd was negatively associated with TSH and BCd was positively associated with TT3, while PFASs mainly affected FT4, TT4, and TT3, with gender differences. In males, 7 PFASs had a significant negative mixture effect on TT3 and TT4, while the direction of effect of PFASs in females differed, with PFOS and PFUnDA having a significant positive correlation with FT4 and TT4 while PFDA having a significant negative correlation with FT4 and TT4. ConclusionIn a healthy population with no occupational exposure, co-exposure to cadmium, lead and PFASs affects different thyroid hormone indicators, and such effect could be gender-related, indicating that the effect of mixed exposure to metal and emerging compounds on thyroid functions warrants further attention.

ABSTRACT

Objective To explore the relationship between the expression of DEAO-box helicase 5(DDX5) and transcription factor 12(TCF12) with amyotrophic lateral sclerosis ( ALS ) hippocampal lesions by detecting the expressions and the interaction of DDX5 and TCF12 in the hippocampus of SOD1-G93A mutant ALS transgenic mice. Methods Forty- two pairs of SOD1-G93A mutant ALS transgenic mice and wild-type mice were divided into three groups at the age of 95 days (early onset stage), 108 days (middle onset stage) and 122 days (late onset stage). RT-PCR, Western blotting and double immunofluorescence labeled technique were used to detect the expressions of DDX5 and TCF12 in the hippocampus. Co-immunoprecipitation assasy was used to detect the interaction between DDX5 and TCF12. Results Compared with the wild-type mice of the same age, DDX5 and TCF12 mRNA in the hippocampus of SOD1-G93A mutant ALS transgenic mice were unchanged, but DDX5 and TCF12 protein were up-regulated significantly at day 95, 108 and 122. DDX5 and TCF12 positive cells were found in both DG area and hippocampus proper, and DDX5 and TCF12 were co-localized with neurons. The immunoreactivities of DDX5 and TCF12 in the hippocampus of SOD1-G93A mutant transgenic mice were elevated compared with wild-type mice at the same time point. Co-immunoprecipitation assasys confirmed that there existed interactions between DDX5 and TCF12 protein. Conclusion DDX5 and TCF12 protein are up-regulated in the hippocampal tissues of SOD1-G93A mutant ALS transgenic mice. The abnormal expressions of DDX5 and TCF12 are involved in the hippocampal lesions of ALS.

ABSTRACT

BACKGROUND@#Coronary artery disease (CAD) in octogenarians (age of ≥80 years) has a high risk of mortality and high medical expenses. Research shows that the prevalence of CAD is higher among octogenarians than that among younger people, but few such patients undergo percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). This study aimed to evaluate different treatments with respect to their clinical effects and impacts on quality of life of octogenarians with CAD.@*METHODS@#Data of 519 octogenarians with CAD consecutively treated at Beijing Anzhen Hospital, Capital Medical University (Beijing, China) from January 2010 to January 2016 were collected in this study. The patients were categorized into three groups based on the treatments they received: the PCI group (n = 292), CABG group (n = 110), and medical treatment group (n = 117). The followings were recorded during follow-up: clinical data, death (all-cause and cardiovascular-related), re-hospitalization time, Seattle Angina Questionnaire (SAQ) score, and occurrence of hemorrhagic events (cerebral bleeding, gastrointestinal bleeding, and dermal ecchymosis).@*RESULTS@#The median follow-up duration was 25.0 (25th, 75th percentile: 17.0, 55.5) months among 417 patients. The all-cause death rates (28.2% vs. 12.0% and 14.6%, respectively) and cardiovascular-related death rates (15.4% vs. 3.8% and 6.4%, respectively) were significantly higher in the medical treatment group than those in the PCI group and CABG group (all P < 0.05). The re-hospitalization rate for cardiovascular events was significantly lower in the CABG group than those in the PCI group and medical treatment group (3.8% vs. 12.8% and 14.9%, respectively) (χ = 8.238, P = 0.018). The SAQ scores of physical limitation, angina frequency, treatment satisfaction, and disease perception were significantly higher in the PCI group and CABG group than those in the medical treatment group (all P < 0.05). No significant difference in the angina stability score was observed among the three groups (F = 3.179, P = 0.204).@*CONCLUSION@#PCI and CABG result in reduced mortality and better quality of life in octogenarians with CAD.

ABSTRACT

ABSTRACT In a pot experiment, clonal ramets of Cynodon dactylon, a stolon herbaceous plant, were treated with heterogeneous lighting. Proximal ramets (elder ramets) were subjected to shade stress at three different degrees, and stolons between proximal and distal ramets of each pair were treated in a connected or severed manner. Results showed that in moderate shade stress, the number of ramets and leaves, biomass, net photosynthetic rate (Pn), maximum quantum yield (Fv/Fm), effective quantum yield of PSII (ФPSII), and soil and plant analysis development values (SPAD) of proximal ramets were significantly reduced, regardless of whether stolons were kept intact or severed. However, the growth of distal ramets was not significantly influenced, and keeping the stolons intact also did not bring apparent benefits for the whole clonal fragments. These results show that clonal integration does not help alleviate the shade stress suffered by proximal ramets and the costs of distal ramets and does not significantly influence the whole clonal fragments. The possible reasons are that distal ramets may be at the cost of metabolism for resource transportation when the proximal ramets suffer from shade stress; thus, clonal integration is not favorable.

ABSTRACT

Objective: To evaluate the clinical characteristics and survival outcomes of patients with de novo grade 3 or transformed follicular lymphoma (FL). Methods: Fifty-two patients treated at Peking University Cancer Hospital between January 2009 and September 2017 were assessed, including 28 patients with FL 3A grade, 13 patients with FL 3B grade, 11 patients with transformed FL. Baseline characteristics, survival and prognostic factors were analyzed. Results: ① Twenty-six male and 26 female patients were enrolled, including 28 patients with FL 3A grade, 13 patients with FL 3B grade, 11 patients with transformed FL. ②The 3-year progression-free survival (PFS) and overall survival (OS) for the entire cohort were 56.0% and 80.6%, respectively. Patients with international prognostic index (IPI) score 0-1 demonstrated significantly better 3-year PFS (80.3% vs 20.1%; t=18.902, P<0.001) and OS (95.7% vs 57.0%; t=10.406, P<0.001) than patients with IPI score 2-3. Three-year PFS (94.1% vs 37.2% vs 25.2%; P=0.002) and OS (100.0% vs 76.0% vs 59.8%; P=0.020) were also significantly different among patients with FLIPI 1 score 0-1, 2, ≥3. FLIPI 2 score was also identified as a prognostic factor for 3-year PFS (68.4%, 0, 0; P=0.001) and OS(87.5%, 76.2%, 0; P=0.003). ③Multivariate analysis indicated a significant association of PFS (HR=3.536, P=0.015) and OS (HR=15.713, P=0.015) with IPI. FLIPI 2 was associated with OS (score 0-1, HR=0.078, P=0.007; score 2, HR=0.080, P=0.022). Conclusion: De novo grade 3 or transformed FL might be a group of curable disease with current treatment strategies. IPI is still a prognostic tool in this scenario.

ABSTRACT

Objective: To evaluate the prognostic value of (18)F-fluorodeoxyglucose positron emission tomography (PET)/computed tomography (CT) in patients with diffuse large B cell lymphoma (DLBCL) undergoing autologous hematopoietic stem cell transplantation (auto-HSCT). Methods: Forty-eight patients with DLBCL treated at Peking University Cancer Hospital between November 2010 and December 2014 were assessed. All patients underwent PET/CT scanning prior to or after auto-HSCT. Correlation analysis was done based upon patients characteristics, PET/CT scan results and survival. Results: ①Among 48 patients, 27 was male, 21 female, median age was 43 (17-59) years old. ② Patients with negative pre-auto-HSCT PET/CT assessment demonstrated significantly better 3-year progression free survival (PFS) (87.1% vs 53.3%, χ(2)=7.02, P=0.019) and overall survival (OS) (90.3% vs 60.0%, χ(2)=6.51,P=0.022) than patients with positive pre-auto-HSCT PET/CT assessment. Three-year PFS (94.1% vs 30.0%, χ(2)=22.75, P=0.001) and OS (97.1% vs 40.0%, χ(2)=21.09, P=0.002) were also significantly different between patients with negative and positive post-auto-HSCT PET/CT assessment. ③ Multivariate analysis indicated a significant association of PFS (HR=13.176, P=0.005) and OS (HR=20.221, P=0.007) with post-auto-HSCT PET/CT assessment. Number of prior treatment regimens was associated with PFS (HR=10.039, P=0.040). ④ Harrell's C index revealed that the value of combined use of number of prior treatment regimens and post-auto-HSCT PET/CT assessment was superior to either one used alone in PFS (Harrell's C values were 0.976, 0.869 and 0.927 in combined use, number of prior treatment regimens and post-auto-HSCT PET/CT assessment, respectively), and the combined use of ECOG performance status and post-auto-HSCT PET/CT assessment significantly increased the Harrell's C index in OS (Harrell's C values were 0.973, 0.711 and 0.919 in combined use, ECOG performance status and post-auto-HSCT PET/CT assessment, respectively). Conclusions: Post-auto-HSCT PET/CT assessment is the main predictor of outcomes in DLBCL patients receiving auto-HSCT. Combined use of post-auto-HSCT PET/CT assessment and number of prior treatment regimens and ECOG performance status is a better prognostic tool in patients with DLBCL undergoing transplantation.

ABSTRACT

The dimension of the levator hiatus is a possible predictor of pelvic organ prolapse (POP). This retrospective study investigated 360 women who went to urogynecological clinic for pelvic floor discomfort. Levator hiatus dimensions were obtained by three-dimensional transperineal ultrasound and results were compared between women with and without significantly objective prolapse (International Continence Society POP quantification, grade 2 or higher). Receiver operating characteristic (ROC) curve analyses were performed to determine valid screening index for detecting abnormal levator hiatus distensibility. Women with significantly objective prolapse had significantly higher levator hiatus dimensions than those without (all P < 0.001). ROC curve analyses confirmed that hiatal area (HA) of 19.5 cm during Valsalva maneuver can be used as single-screening index for abnormal levator hiatus distensibility with sensitivity of 0.80 and specificity of 0.70. In this study, we used a two-step method and achieved higher sensibility (0.80 vs. 0.87) without reducing specificity (0.70 vs. 0.71) compared with a single-screening index method. As a result, we suggest that HA ⩾ 19.5 cm during Valsalva maneuver is an indicator of abnormal levator hiatus distensibility in Chinese women and that the two-step method has higher sensitivity in detecting abnormal distensibility.

ABSTRACT

Objective To evaluate the value of hysterosalpingo-contrast-sonography in assessment the patency of fallopian tube after tubal interventional recanalization. Methods A total of 56 cases of fallopian tube recanalization were performed in Shanghai Putuo Hospital from January 2015 to September 2016. Seventy-eight fallopian tubes in 40 cases were treated with hysterosalpingo-contrast-sonography and hysterosalpingography before recanalization. Totally 106 fallopian tubes in 56 cases were performed hysterosalpingography before and after recanalization. Seventy-eight fallopian tubes in 40 cases were evaluated with hysterosalpingo-contrast-sonography before recanalization. The patency of the tubal was assessed by hysterosalpingo-contrast-sonography 3 months after recanalization, and the re-occlusion rate was calculated. Chi square test was used to compare the results of hysterosalpingo-contrast-sonography and hysterosalpingography before and after recanalization, and the patency of fallopian tube at just after operation and 3 months after recanalization. Results Before recanalization, the results of hysterosalpingo-contrast-sonography showed 40 obstructed and 38 partially obstructed. The results of hysterosalpingography showed 44 obstructed and 34 partially obstructed. There was no significant difference between the results of hysterosalpingo-contrast-sonography and hysterosalpingography. Before recanalization, 106 fallopian tubes in 56 cases showed 53 obstructed and 53 partially obstructed. After recanalization, 72 unobstructed, 34 partially obstructed, and no obstruction. However, 22 fallopian tubes were re-obstructed 3 months after recanalization, and the rate of re-occlusion was 20.7% (22/106). The re-occlusion rate of unobstructed fallopian tubes was 19.4% (14/73) and the re-occlusion rate of partially obstructed fallopian tubes was 23.5% (8/34). There was no statistically significant difference between them. Conclusions Re-obstruction may be present in some cases 3 months after tubal recanalization. Hysterosalpingo-contrast-sonography can provide an objective and effective basis for guiding pregnancy plan after tubal recanalization.

ABSTRACT

Objective To visualize the pelvic floor structures by translabial three‐dimensional(3D) ultrasonography performed during labor and immediately after delivery, and to observe the morphological changes of levator hiatus in intrapartum women. Methods Totally 62 nulliparous women with singleton pregnancy and cephalic presentation in labor ward underwent intrapartum translabial 3D ultrasound examination before cervical dilatation, at 10 cm dilatation and immediately after delivery. Volume datasets were obtained at rest, biometric measurements and observation of the morphological changes of levator hiatus in different stages were determined in the axial plane. Comparative analyses of parameters in three stages were carried out. Results Translabial 3D ultrasound demonstrated the pelvic floor structures of intrapartum women well. All biometric measurements of the hiatus before cervical dilatation were the smallest and became the largest at 10 cm dilatation, showed statistically significant differences. The measurements after delivery got smaller immediately but still significantly larger than those before cervical dilatation ( P <0 0.01). Conclusions Translabial 3D ultrasound examination of the pelvic floor during labor and within the first 2h after delivery is feasible. It seems to be an effective tool to visualize pelvic floor structures in intrapartum women. Hiatal enlargement may be a common consequence of vaginal childbirth.

ABSTRACT

This study was purposed to investigate the expression of latent membrane protein 1 (LMP-1) and CD68 in Hodgkin's lymphoma (HL) patients with EB virus infection and to analyze the relation of LMP-1 expression and CD68(+) tumor-associated macrophage count with clinical features and prognosis of HL patients. The expression of LMP1 and count of CD68(+) TAM were detected by immunohistochemical staining in tissue specimens of 72 HL patients; their correlation with clinical features and prognosis of HL patients was analyzed by using statistical method. The results showed that among tissue specimens of 72 HL patients, the positive rate of LMP-1 expression was 18.1% (13/72), the CD68(+) TAM count was more higher in LMP-1 positive expression [250 of CD68(+) TAM/high power field (hpf) is used as demarcation point] (P = 0.003). The statistical analysis showed that the LMP-1 positive expression was more observed in mixed type HL patients (P = 0.000); the positive rate of LMP-1 expression was much high in HL patients with albumin <40 g/L and age ≥ 45 years (P < 0.05). There was no relation of LMP-1 expression and CD68(+) TAM count with the short term therapeutic efficacy of HL patients, but the overall survival time of LMP-1 positive patients among patients followed-up for ≥ 5 years was short (P < 0.05). Moveover, no correlation of CD68(+) TAM count with the overall survival time of HL patients was found. It is concluded that the high count of CD68(+) TAM is more observed in LMP-1 positive expression of HL tissue, the LMP-1 expression states relates both with the pathological types, age and albumin level of patient with HL. The HL patients with LMP-1 positive expression have poor prognosis, suggesting that LMP-1 may be a new prognostic marker for HL patients.

ABSTRACT

Minimal important difference (MID) is a concept in regards of efficacy evaluation in recent years. MID has its features and clinical significance. MID methods include anchor-based methods, distribution-based methods, expert consensus methods, literature analysis methods, and so on. All these methods have their own advantages and disadvantages. In confirming MID, you'd better use them comprehensively according to the research objectives. The significance, range, and evaluation methods of MID in the clinical research of Chinese medicine were clarified. It is necessary to strengthen MID correlated researches and applications.
