ABSTRACT
Objective To explore the effects from the synergy of substrate stiffness and hypoxia on epithelial mesenchymal transition (EMT) of colon cancer cells SW480 by simulating the microenvironment of human colon cancer tissues. Methods Polyvinyl alcohol gels with different stiffness ( 4. 5, 20, 40 kPa) were prepared to simulate the stiffness of each part of colon cancer tissues. The morphological change of cells on substrate with different stiffness was detected under simulated hypoxia ( CoCl2 ) environment. The expression of hypoxia inducible factor (HIF-1α), and EMT markers E-cadherin, Vimentin, Snail 1 were detected by Western blot. The mRNA expression of E-cadherin, Vimentin, Snail 1, matrix metalloproteinase-2 ( MMP-2), and MMP-9 was detected by quantitative real-time PCR ( qRT-PCR). Results Under simulated hypoxia environment, with the increase of substrate stiffness, the SW480 cells spreading area increased, and transformed from round shape into irregular polygon. The EMT of SW480 could be enhanced through up-regulating expression of Vimentin, Snail 1, MMP-2, MMP-9, and down-regulating expression of E-cadherin. Conclusions This study is important for exploring the synergistic effect of substrate stiffness and hypoxia on the EMT of colon cancer cells as well as the molecular mechanism.
ABSTRACT
Objective:To evaluate the role of aryl hydrocarbon receptor (AhR) in the down-regulation of Clara cell secretory protein (CCSP) expression during endotoxin-induced lung injury in rats.Methods:Twenty-four clean-grade healthy male Sprague-Dawley rats, aged 8 weeks, weighing 200-250 g, were divided into 4 groups ( n=6 each) using a random number table method: normal control group (group C), acute lung injury (ALI) group, ALI+ AhR antagonist group, and ALI+ vehicle group. Lipopolysaccharide(LPS) 1 mg/kg was intratracheally instilled to develop the model of lung injury, while the equal volume of normal saline was given instead in group C. At 2 h before LPS injection, AhR antagonist 6, 2′, 4′-trimethoxyflavone solution 5 mg/kg (diluted to 1 ml in dimethyl sulfoxide solution) was intraperitoneally injected in ALI+ AhR antagonist group, while dimethyl sulfoxide solution 1 ml was given in ALI+ vehicle group. The rats were sacrificed under anesthesia at 48 h after LPS administration. The left lung was lavaged and the broncho-alveolar lavage fluid (BALF) was collected for determination of the concentrations of CCSP by enzyme-linked immunosorbent assay, and the expression of CCSP in the bronchial epithelium in right lung tissues was determined by immunohistochemistry. Results:Compared with group C, the expression of CCSP in the bronchial epithelium was significantly down-regulated, and the concentrations of CCSP in BALF were decreased in the other three groups ( P<0.05 or 0.01). Compared with ALI group and ALI+ vehicle group, the histopathological injury was significantly reduced, the expression of CCSP in the bronchial epithelium was up-regulated, and the concentrations of CCSP in BALF were increased in ALI+ AhR antagonist group ( P<0.01). Conclusions:AhR partially mediates the down-regulation of CCSP expression during endotoxin-induced lung injury in rats.
ABSTRACT
Objective:To analyze the changes in plasma endothelin-1 (ET-1) concentrations in the patients with acute respiratory distress syndrome (ARDS).Methods:Fourteen patients with ARDS induced by trauma, 8 males and 6 females, aged 19-80 yr, were studied. The severity of ARDS was graded according to the Berlin definition of ARDS after admission to intensive care unit (ICU). Venous blood samples were obtained on 1st, 3rd and 5th days after admission to ICU, the plasma ET-1 concentrations were measured by radioimmunoassay, the pulmonary vascular permeability index (PVPI) was determined by PiCCO technique, and multiple organ dysfunction (MOD) score and lung injury score (LIS) were assessed. Spearman correlation of plasma ET-1 concentrations with MOD score, LIS and PVPI was analyzed.Results:MOD score, LIS, PVPI and plasma ET-1 concentrations were significantly decreased in mild ARDS patients ( n=5) as compared with moderate ARDS patients ( n=9, P<0.05). The plasma ET-1 concentration was positively correlated with MOD score, LIS and PVPI ( r=0.69, 0.76, 0.62, P<0.001). Conclusions:Plasma ET-1 concentrations can reflect the pulmonary vascular permeability and even the severity of the disease in the early stage of ARDS, so it is necessary to carry out dynamic monitoring in the patients.
ABSTRACT
Objective:To explore the clinical characteristics of pneumocystis carinii pneumonia (PCP) after kidney transplantation.Methods:From January 2020 to January 2022, clinical data were retrospectively reviewed for 13 renal transplant recipients with pneumocystis pneumonia diagnosed by metagenomics next generation sequencing (mNGS). There were 3 females and 10 males with an age range of (46±10) years.The median time of postoperative onset was 10(2-21) months; The major clinical manifestations included fever ( n=11), cough ( n=7), expectoration ( n=6) and dyspnea ( n=11). Paired t-test was employed for analyzing the laboratory results at admission and discharge. Results:The diagnosis was confirmed by the detection of NGS in alveolar lavage fluid or venous blood.The levels of G test, LDH test, total T lymphocyte absolute count (CD3+ Abs), inhibitory/cytotoxic T lymphocyte count (CD3+ CD8+ Abs) and auxiliary/induced T lymphocyte absolute count (CD3+ CD4+ Abs) were (543.27±440.49) pg/ml, (529.98±222.43)U/L and (191.92±119.42)/μl, (87.33±50.59)/μl and (106.92±87.42)/μl at admission and (69.58±50.21) pg/ml, (285.38±46.62 U/L), (888.58±672.99)/μl, (336.83±305.21)/μl and (520.08±388.76)/μl at discharge.The differences were statistically significant ( P<0.001, P=0.002, 0.006, 0.017, 0.005). All of them received compound sulfamethoxazole and caspofungin.Except for one death due to septic shock after 21-day treatment, 12 cases were cured. Conclusions:mNGS test is one of the important tool for an early diagnosis of PCP.Combined use of compound sulfamethoxazole and caspofungin is an effective anti-infective regimen.And immune function monitoring is vital for adjusting antibiotic and immunosuppressive regimens.
ABSTRACT
Objective:To evaluate the efficacy of Chaichuan Tongren Mixture supplemented with hysteroscopic recanalization in the treatment of tubal obstructive infertility of liver depression and qi stagnation type.Methods:A total of 60 patients with tubal obstructive infertility of liver depression and qi stagnation type who met the inclusion criteria were selected, between August 2018 and June 2020, and they were divided into the observation group with 31 cases and the control group with 29 cases, according to the random number table method. The control group was treated with hysteroscopic recanalization, while the observation group was given Chaichuan Tongren Mixture on the basis of the control group. Both groups were treated for 4 months and followed up for 12 months. TCM syndromes were scored before and after treatment, and prostaglandin E 2 (PGE 2) was detected by fully automatic biochemical analyzer and levels of TNF-α, CRP and IL-6 were measured by ELISA. The tubal patency of patients after treatment was observed, the pregnancy status was recorded after the end of follow-up and the clinical efficacy was evaluated. Results:The total effective rate was 96.77% in the observation group and that in the control group was 75.86% ( χ2=4.01, P<0.01). The scores of breast distending pain, irregular menstruation, dark purple menstrual flow and lumbosacral pain in the observation group after treatment were significantly lower than those in the control group ( t values were 17.69, 21.67, 20.89, 14.67, 18.20, respectively, all Ps<0.001). After treatment, the levels of serum PGE 2, TNF-α, CRP, and IL-6 were significantly lower in the observation group than those in the control group [(65.31±6.73) ng/L vs. (87.10±8.85) ng/L, t=10.78; (6.90±0.71) ng/L vs. (11.35±1.23) ng/L, t=17.30; (2.47±0.25) mg/L vs. (5.10±0.52) mg/L, t=25.23; (12.38±1.26) ng/L vs. (30.16±3.15) ng/L, t=29.05] ( P<0.01). After treatment, there was statistical significance in the total effective rate of tubal patency of 96.8% (30/31) in the observation group compared to 79.3% (23/29) in the control group ( χ2=4.43, P<0.01). At the end of follow-up, the pregnancy rate was 71.0% (22/31) in the observation group and 44.8% (13/29) in the control group, and the difference was statistically significant ( χ2=4.21, P<0.01). Conclusion:The Chaichuan Tongren Mixture supplemented with hysteroscopic recanalization can reduce the levels of inflammatory mediators and increase the pregnancy rate of patients with tubal obstructive infertility of liver depression and qi stagnation type.
ABSTRACT
Objective:To evaluate the efficacy and safety of continuous infusion of low-dose intravenous (Ⅳ) heparin during perioperative period of simultaneous pancreas-kidney (SPK) transplantation for donation after citizen death (DCD) donor to prevent pancreatic thrombosis post-transplantation.Methods:From January 2015 to August 2019, 46 DCD donors undergoing SPK were divided into retrospective cohort groups 1 ( n=27) and 2 ( n=19). Group 1 received aspirin enteric-coated tablets only at Day 1 post-SPK. In Group 2, 5-7 days of continuous infusion of heparin 260 IU per hour at Day 1 post-SPK was followed by a daily intake of aspirin enteric-coated tablets of 100 mg. Incidence of thrombus, recovery of graft function and adverse reactions of anticoagulant therapy were observed. Results:Thrombosis occurred in (5.3%, 1/19 vs 14.8%, 4/27) in heparin and non-heparin groups. Thrombosis and graft loss were significantly lower in heparin group than those in non-heparin group ( P<0.05). Conclusions:Continuous infusion of low-dose heparin vein is effective and safe in preventing thrombosis after SPK transplantation.
ABSTRACT
Background@#and Purpose Previous studies suggested increased visit-to-visit variability of total cholesterol (TC) is associated with stroke. This study aimed to investigate the associations of various lipids measurements variability and the risk of stroke and stroke type (ischemic and hemorrhagic stroke). @*Methods@#Fifty-one thousand six hundred twenty participants in the Kailuan Study without history of myocardial infarction, stroke, and cancer who underwent three health examinations during 2006 to 2010 were followed for incident stroke. Variability in TC, triglycerides, high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) measurements were measured using the coefficient of variation (CV), standard deviation (SD), variability independent of the mean (VIM), and average real variability (ARV). @*Results@#During a median of 6.04 years of follow-up, 1,189 incident stroke (1,036 ischemic and 160 hemorrhagic stroke) occurred. In the multivariable-adjusted model, the hazard ratio (HR) comparing participants in the highest versus lowest quartile of CV of HDL-C were 1.21 (95% confidence interval [CI], 1.02 to 1.45; P for trend=0.013) for ischemic stroke. The highest quartile of CV of LDL-C was associated with 2.17-fold risk of hemorrhagic stroke (HR, 2.17; 95% CI, 1.25 to 3.75; P for trend=0.002) compared with the lowest quartile. We did not observe any significant association between TC and triglycerides variability with any of stroke. Consistent results were obtained when calculating variability index using SD, VIM, or ARV. @*Conclusions@#These findings suggest the high visit-to-visit HDL-C and LDL-C variability were associated with an increased incidence of ischemic and hemorrhagic stroke, respectively.
ABSTRACT
Organ shortage is one of the important factors restricting the development of human organ transplantation. The identification and referral of potential donors determine the total scale of organ donation. Whether potential donors can be identified and referred is the most important reason for the difference of organ donation rates in different regions. This paper interprets the chapter of the identification and referral of potential donors in the Guide to the Quality and Safety of Organs for Transplantation (6th edition) issued by European Union in order to provide reference for the staff of organ procurement organization and related medical personnel in China and improve the organ donation rate in China.
ABSTRACT
Objective:To evaluate the association between smoking and the risk of type 2 diabetes (T2DM) incidence among Asian adults based on the prospective studies.Methods:Prospective studies conducted on Asian adults through May, 2019 were retrieved from the following databases: SinoMed, CNKI, VIP, WanFang, PubMed, Web of Science, Embase, and Cochrane Library. Then data were extracted on smoking status, smoking quantity, the number of newly-onset T2DM cases, and effect sizes.Results:A total of 31 studies were included. There were 2 159 787 investigators, 599 340 (27.75%) smokers, and 124 883 (5.78%) T2DM cases identified during the mean follow-up period of 8.3 years. Compared with non-smokers, the combined relativerisk ( RR) and 95% confidence interval ( CI) of current smokers and quitting smokers were 1.52 (1.34- -1.72) ( P<0.001) and 1.22 (1.09- -1.37) ( P=0.047), respectively. The RR and 95% CI of light smokers (<20/day), moderate smokers (20- -29/day), and heavy smokers (≥30/day) were 1.31(1.21- -1.53) ( P=0.001),1.42(1.14- -1.76)( P=0.212), and 2.17(1.50- -3.16) ( P=0.198), respectively. In males and females, the RR and 95% CI were 1.15 (1.08- -1.21) ( P<0.001) and 1.20 (1.11- -1.30) ( P=0.038), respectively. In addition, compared with non-smokers, the RR and 95% CI of current smokers were 1.57 (1.22- -2.03) ( P<0.001) and 1.47 (1.30- -1.66) ( P=0.063) during the follow-up periods of less than and more than 8.0 years, respectively, while the RR and 95% CI of quitters were 1.23 (1.06- -1.43) ( P=0.091)and 1.20 (1.07- -1.34) ( P=0.041), respectively. Conclusions:Prospective studies based on Asian adults have shown that smoking significantly increases the risk of diabetes incidence. That is, as cigarette consumption increases, the risk of diabetes increases accordingly. Moreover, compared to males, the risk for female smokers is greater. In addition, longer durations of smoking cessation are associated with a lower risk of T2DM.

ABSTRACT
Objective@#To explore the association between dust exposure and the incidence of hypertension in male coal miners.@*Methods@#Using the method of retrospective cohort study,a hypertension cohort of colliery in Henan Province was established in January 2006. From 2006 to 2017,all the male coal miners in a colliery who were exposed to dust were selected into the exposure group including tunneling, mining,auxiliary and combining workers, and workers from administrative logistics departments who were not exposed to dust were selected into the control group. The eligible participants should satisfy following conditions: working more than one year, with clear and complete record of occupation change, and with complete archives and reliable diagnosis of occupational health surveillance. The exclusion criteria of participants were with hypertension at the baseline of study or with heart,liver,kidney diseases and malignant tumors. A total of 12 647 participants were enrolled in this study (11 663 in the exposure group and 984 in the control group). The follow-up period was from January 2006 to December 2017,with a total follow-up of 89 259.75 person-years. Questionnaires and physical measurements were used to collect general demographic characteristics, occupational exposure history and occupational health surveillance data of all participants. The Cox proportional hazards regression model was used to estimate the association between the dust exposure and the incidence of hypertension.@*Results@#During the follow-up period, 2 549 new-onset hypertension patients were identified with an incidence density of hypertension about 2 855.71 per 100 000 person-years. The incidence density of hypertension was 2 967.58 per 100 000 person-years in the exposure group, and 1 643.85 per 100 000 person-years in the control group. The results of multivariate Cox proportional hazards regression model showed that after the adjustment of marriage, age, smoking, alcohol drinking and body mass index,the risk of hypertension was higher in the exposure group compared with the control group (HR=1.692, 95%CI: 1.410-2.032). Further analysis showed that compared with workers from administrative logistics departments,the risk of hypertension in tunneling,mining and auxiliary working was 1.629(1.345-1.973),1.677(1.374-2.046) and 1.782(1.475-2.151),respectively.@*Conclusion@#Dust exposure may increase the risk of hypertension in male coal miners.
ABSTRACT
OBJECTIVE: To compare the results of occupational health risk of 2-butoxyethanol(2-BE) by two risk assessment methods. METHODS: Occupational health investigation and detecting 2-BE level in workplace were carried out in a bicycle manufacturing factory in Tianjin City, a printing factory in Shenzhen City and an automobile manufacturing factory in Beijing City. The occupational health risk of 2-BE was assessed by Singapore's semi-quantitative risk assessment model and occupational hazards risk assessment index method. The risk classification results of the 2 risk assessment methods were compared and analyzed. RESULTS: The results of Singapore's semi-quantitative risk assessment method showed that all the 2-BE risk ratios of the decals workshop in the bicycle manufacturing factory, the binding and printing workshops of the printing factory, the spray finishing and the intermediate painting and the electrophoresis workshops of the automobile manufacturing factory were 0.4. The classification of 2-BE risk ratios belongs to low risk level. The results of occupational hazards risk assessment index method showed that the risk ratios of decals workshop in the bicycle manufacturing factory, the binding and printing of the printing factory, the spray finishing and the intermediate painting and the electrophoresis of the automobile manufacturing factory were 0.4, 0.4 and 0.2, respectively, which correspondence to low, low and negligible risk classification, respectively. The two methods were consistent with the appraisal positions of decals post in the bicycle manufacturing factory and the evaluation of binding and printing positions of a printing factory, although the risk assessment results of key positions in the paint shop of an automobile manufacturing industry were inconsistent. CONCLUSION: The occupational hazard risk assessment index method takes into account of the health effects, exposure conditions and operating conditions, and can comprehensively and accurately assess the occupational health risks caused by 2-BE.
ABSTRACT
Objective To evaluate the effectiveness of salvage liver transplantation ( SLT) versus repeat hepatectomy (RH) in post-hepatectomy recurrent hepatocellular carcinoma. Methods Data from 1 January 1990 to 31 July 2018 were retrieved from the Cochrane library, PubMed, EMbase, Wan Fang Data, CBM, CNKI, VIP and other databases. The collected publications were all on case-control studies comparing SLT with RH for post-hepatectomy recurrent hepatocellular carcinoma. The literatures’ quality and the data of each study were evaluated and analyzed using RevMan. Relative risk (RR) and 95% confidence interval (CI) were used. Results Five articles which included 525 patients were enrolled. There were no signifi-cant differences between SLT and RH on the 1-, 3-and 5-year overall survival (P＞0. 05 for all). Howev-er, for the 1-year (RR=2. 86, 95% CI: 1. 37～5. 97, P＜0. 05), 3-year (RR=2. 57, 95% CI: 0. 99～6. 70, P=0. 05), and 5-year disease-free survivals (RR=4. 79, 95% CI: 1. 88～12. 25, P＜0. 05), PLT was significantly better than RH. Conclusion The effectiveness of SLT was superior to RH in the treatment of post-heptectomy recurrent hepatocellular carcinoma. However, considering the similar overall survival rates, RH is still an important treatment option for post-hepatectomy recurrent hepatocellular carcinoma because of liver donor shortage.

Objective To evaluate the efficacy of sirolimus (SRL) after liver transplantation for hepatocellular carcinoma (HCC).Methods The information up to January 2018 was retrieved from Cochrane library,Pubmed,EMbase,CBM,CNKI,VIP.Collected publications were all about casecontrol study of SRL versus calcineurin inhibitors (CNIs) after liver transplantation for HCC.After evaluating the literatures' quality and extracting the data,RevMan 5.3 was used to analyze the data of each study.Results A total of 13 articles including 4181 patients were enrolled.There was no significant difference between SRL and CNIs in 3 and 5 year diseasefree survival (RR=1.13,95％CI:0.97-1.31,P=0.11;RR=1.07,95%CI:0.92-1.24,P=0.37),however,the 1-,3-and 5-year overall survival rate and 1-year disease-free survival rate in SRL were significantly higher than CNIs (RR=1.09,95％CI.:1.03-1.15,P=0.005;RR=1.08,95％CI:1.02-1.14,P =0.006;RR =1.11,95％CI:1.00-1.23,P =0.05;RR=1.14,95％CI:1.05-1.24,P =0.001).Conclusion There was no significant difference between SRL and CNIs in 3-and 5-year disease-free survival,but the 1-,3-and 5-year overall rate and 1-year disease-free survival rate in SRL was significantly higher than in CNIs.
ABSTRACT
Objective To investigate the risks of self-rated health in the ≥55-year elderly in Beijing and the occurrence of stroke.Methods The subjects (n=2 101;aged ≥55) from Beijing longitudinal study of aging (BLSA) were collected by Xuanwu Hospital,Capital Medical University from January 1992 to December 2016.One hundred and twenty-one subjects with stroke at baseline and 92 with incomplete information were excluded,and finally,1 888 elderly patients without cerebrovascular disease at baseline were included in the analysis.Based on the actual situation,the self-rated health was to identify an item that matched their current state from good,general to poor.The deadline for the survey was December 31,2012.The competitive risk model was used to assess the health self-rated status and the risk of stroke.Non-stroke deaths,including cancer and car accidents were treated as competitive events.Results Of the 1 888 subjects enrolled,946 (50.1%) self-rated health were good,616 (32.6%) were general,and 326 (17.3%) were poor;438 (23.2%) had stroke,751 (37.8%) had non-stroke death,and 699 (37.0%) were right censored data.Using the competing risk model and adjusting the age,sex,living area,marital status,education level,smoking,alcohol consumption,physical exercise,hypertension,diabetes mellitus,coronary heart disease,and body mass index,the occurrence of stroke in patients with poor self-rated health was 1.44 times (95%CI 1.11-1.87,P<0.01) as good as those who were good.Conclusion In the self-rated health of the elderly ≥55 years old in Beijing,the people with poor self-rated health increased the occurrence of stroke after considering the competitive risks.
