Risk factors for infection in patients undergoing shoulder arthroscopy: a systematic review and meta-analysis. J Hosp Infect 2024; 150:72-82. [PMID: 38782053 DOI: 10.1016/j.jhin.2024.04.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2024] [Revised: 04/26/2024] [Accepted: 04/28/2024] [Indexed: 05/25/2024]
Abstract
We conducted a meta-analysis to determine the risk of infection following shoulder arthroscopy and to identify risk factors for infection. We systematically searched the PubMed/Medline, Embase and Cochrane Library databases, as well as the reference lists of previous systematic reviews and meta-analyses; manual searches were also performed. A random-effects model was employed to estimate pooled odds ratios (ORs), based on sample size, the P-value of Egger's test and heterogeneity among studies. Of the 29,342 articles screened, 16 retrospective studies comprising 74,759 patients were included. High-quality evidence showed that patients with diabetes (OR, 1.30; 95% confidence interval (CI), 1.20-1.41) or hypertension (OR, 1.26; 95% CI, 1.10-1.44) had a higher risk of infection, while moderate quality evidence showed that patients with obesity (body mass index ≥30 kg/m2) (OR, 1.42; 95% CI, 1.28-1.57), those who were male (OR, 1.65; 95% CI, 1.12-2.44), those who had an American Society of Anesthesiologists (ASA) class ≥3 (OR, 2.02; 95% CI, 1.02-3.99) and those who had a history of smoking (OR, 2.44; 95% CI, 1.39-4.28) had a higher risk of infection. The meta-analysis revealed that there was no association between age, time of surgery, or alcohol consumption and infection. This meta-analysis identified six significant risk factors for infection following shoulder arthroscopy including diabetes, obesity, hypertension, male sex, ASA class, history of smoking. These patient-related risk factors may help identify postoperative patients at higher risk for infection following shoulder arthroscopy.

Poult Sci 2023; 102:103070. [PMID: 37725861 PMCID: PMC10518710 DOI: 10.1016/j.psj.2023.103070] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Revised: 08/22/2023] [Accepted: 08/23/2023] [Indexed: 09/21/2023] Open
Abstract
Freshly slaughtered carcasses need to be chilled to improve product quality, meat safety, and processing efficiency. This research investigated the effect of subzero saline chilling (SSC) on broiler carcasses with or without prechilling in icy water. Water immersion chilling at 0.5°C (WIC) or SSC at 4% NaCl/-2.41°C (SSC) was a major chilling step. For the combination of pre- and postchilling, the warm water immersion chilling (WWIC) at 10°C was used as prechilling and the WIC as postchilling (WWIC-WIC), and WIC was used as prechilling and the SSC as postchilling (WIC-SSC). The internal temperature of breast fillets was monitored during chilling. Carcasses in a prechiller were transported to a postchiller when their internal temperature reached 15°C. Chilling was completed when the carcass temperature reached 4.4°C or below, and breast fillets were harvested at 3-h postmortem to measure the pH and sarcomere length. Color (L*, a*, and b*) values were evaluated on both breast skin and skinless breast surfaces. Meat tenderness was evaluated using the breast fillets after overnight storage and cooking to an internal temperature of 76°C. The carcasses in the SSC and WIC-SSC showed shorter chilling times (85-91 min) than those (100-144 min) of WIC and WWIC-WIC. A higher chilling yield was observed for the carcasses in WIC-SSC, and a lower cooking yield was seen for the carcasses in WWIC-WIC than other chilling methods (P < 0.05). The breast fillets of broilers in the SSC and WIC-SSC showed lower shear forces and longer sarcomere length than the WIC and WWIC-WIC. No difference was found for L* and a* values, while lower b* value was observed in the SSC than the other chilling methods (P < 0.05). Based on these results, chilling of broiler carcasses in the SSC (4% NaCl/-2.41°C) with or without prechilling in WIC at 0.5°C significantly improved chilling efficiency and meat tenderness, with minor color changes on carcasses.

Abstract
Objective: To discuss the efficacy and safety of orthokeratology with increased compression factor (ICF) in myopia correction in children. Methods: It was a prospective cohort study. Data of the right eyes of myopic children who visited the First Affiliated Hospital of Chengdu Medical College for orthokeratology were collected continuously from May 2016 to Dec 2018. All children had low myopia (<3.00 D) or moderate myopia (≥3.00 D), and were grouped using random numbers in Excel to receive orthokeratology with ICF or conventional compression factor (CCF). The axial length (AL), spherical equivalent (SE), best corrected visual acuity (BCVA), near visual acuity (NVA), Efron grade, corneal hysteresis (CH), corneal resistance factor (CRF), corneal-compensated intraocular pressure (IOPcc), tear film break-up time (BUT), higher-order aberrations (HOAs), accommodative amplitude (AA) and accommodative facility (AF) were compared between groups during the 1-year treatment period. The Chi-squared test was used to compare the categorical data, while the independent-sample t-test was performed to assess the measurement data. Results: After 1 year of treatment, there were no statistical differences in AL, SE, BCVA, NVA, Efron grade, CH, CRF, IOPcc, BUT, HOAs, AA and AF between the low myopia ICF group and the low myopia CCF group (all P>0.05). After 6 months of treatment, the AL increased by (0.05±0.03) mm in the moderate myopia ICF group and by (0.08±0.04) mm in the moderate myopia CCF group (t=-3.416, P=0.001). After 1 year of treatment, the AL increased by (0.12±0.04) mm in the moderate myopia ICF group and by, (0.16±0.05) mm in the moderate myopia CCF group (t=-4.017, P<0.001). The SE was (-0.16±0.40) D in the moderate myopia ICF group, significantly different from that in the moderate myopia CCF group [(-0.58±0.60) D; t=3.529, P=0.001]. There were also statistical differences in HOAs, spherical aberrations and AF (all P<0.05), but no statistical differences in BCVA, NVA, Efron grade, CH, CRF, IOPcc, BUT and AA between the two groups (all P>0.05). Conclusions: Orthokeratology with ICF safely and effectively corrected myopia in children during the observation period. It could control the progression of moderate myopia more effectively than that of low myopia.

Abstract
Objective: To investigate the trueness of 4 three-dimensional (3D) facial scanners and to evaluate the applicability of their clinical use. Methods: An art head model was used as the scanning object, and it was scanned by Handyscan 3D scanner in an enclosed environment with a fixed light source to obtain the reference digital model. Three fixed 3D facial scanners (A: 3dMDface; B: Facego Pro; C: RDS Facescan) and a portable hand-held 3D facial scanner (D: Revopoint POP 2) were used to scan the art head model 10 times, and 10 models of each scan group were obtained. The face of the reference model was divided into 16 regions according to anatomy and muscle distributions in the Geomagic Wrap software with saved boundary curves of whole face and each region. The test models were also divided into 16 regions through the curves above after registered with the reference model through "Best fit" function. The root-mean-square error (RMS) of the complete test models and their segmented regions compared with the reference model and its corresponding regions were calculated by 3D comparison function. The smaller the RMS, the higher the accuracy. One-way ANOVA and SNK post-test were used for statistical analysis. Results: RMS of complete test models scanned by A, B, C, D scanners were (0.295±0.005), (0.216±0.053), (0.059±0.012) and (0.103±0.026) mm (F=123.81, P<0.001), respectively. There was significant difference between any two groups (P<0.05). For each facial region, the group D had the best trueness in nasal region, lip region, left orbital region and right orbital region [RMS were (0.079±0.032), (0.061±0.019), (0.058±0.021), (0.081±0.032) mm, respectively], while the group C had the best trueness in frontal region, left buccal region, right buccal region, left zygomatic region, right zygomatic region, left parotideomasseteric region, right parotideomasseteric region, left temporofacial region, right temporofacial region, mental region, left infraorbital region and right infraorbital region [RMS were (0.039±0.011), (0.034±0.007), (0.033±0.007), (0.066±0.023), (0.038±0.022), (0.070±0.030), (0.067±0.024), (0.063±0.029), (0.045±0.023), (0.063±0.006), (0.039±0.010), (0.046±0.008) mm, respectively]. Conclusions: On the basis of art head model scanning, although the overall average deviation between the scanning model and the reference models obtained by the four kinds of 3D facial scanners were small, the portable handheld 3D facial scanner (D) has better accuracy than the fixed 3D facial scanners (A, B, C) in the orbital area, nasal area, lip area and areas with rich features.

Abstract
In recent years, the diagnosis and treatment of gynecologic cancer have entered a new era with the development of precision medicine. The diagnosis and treatment modes for ovarian cancer, cervical cancer, and endometrial cancer are constantly adjusted. The application of molecular targeted drugs and the progress of surgical concepts and technology have greatly improved the survival of patients with ovarian cancer. Immunotherapy and targeted therapy have become a new hot spot in the treatment of cervical cancer. More clinical research data have been accumulated on the comparison of laparoscopic and open radical hysterectomy in cervical cancer. The surgical management of endometrial cancer has been improved, and molecular diagnostics are increasingly used to guide the diagnosis and treatment of endometrial cancer. Meanwhile, it's necessary to realize the limitations and challenges of precision medicine in gynecologic cancer.

Background/Introduction: Congestive heart failure (CHF), the main reason for morbidity and mortality, is considered a serious consequence of myocardial infarction (MI). The use of left ventricular end-diastolic pressure (LVEDP) as a chief indicator of CHF becomes limited because of the possible impairment of cardiac function and induced aortic valve damage during its recording. Echocardiography is the gold standard approach to diagnose structural myocardial dysfunction. However, its ability to predict chronic CHF following MI is still limited. Recently, intraventricular pressure gradient (IVPG) was presented as a non-invasive, highly sensitive preload-independent diastolic function parameter to assess cardiac function, especially during cardiomyopathy. However, there have not been any investigations demonstrating the feasibility of IVPG in the evaluation of post-infarction chronic CHF.
Purpose
This study aimed to investigate the utility of IVPG to assess the heart function in a rat model with chronic CHF following MI with evaluating its capacity to predict these changes.
Methods
Fifty male rats were included. MI was induced via ligation of the left anterior descending artery (LAD) at the level of the atrioventricular junction (MI animals, n = 35). Sham animals were subjected to the same left thoracotomy procedure without LAD ligation (Sham animals, n = 15). Transthoracic conventional echocardiography and colour M-mode echocardiography (CMME) for IVPG were performed in all animals 6 months post-surgery. The next day, animals were anesthetized, ventilated, and euthanized after the recording of hemodynamics. The heart weight, and lung and liver wet-to-dry weight ratios were recorded. J-tree cluster-analysis was performed based on ten echocardiographic variables indicative of CHF.
Results
Based on the cluster analysis, animals were joined into two clusters; CHF+ (n = 22) and named MI/HF+, and CHF- (n = 28) that was joined from sham (n = 15), and MI/HF- (n = 13). MI/HF+ presented the most severe anatomical and echocardiographic changes indicative of CHF with significant reduction of all IVPG indices and impairment of the hemodynamics. The IVPG indices were significantly (P< 0.0001) correlated with the anatomical and echocardiographic findings, LVDP, LVEDP, HR, -dP/dtmin, and Tau. Meanwhile, LVSP was only significantly correlated with apical IVPG (R = 0.677, P = 0.022). dP/dtmax was significantly correlated with total IVPG, basal IVPG, and apical IVPG (R = 0.797, P = 0.017, R = 0.724, P = 0.003, and R = 0.652, P = 0.026 ; respectively). Moreover, total, basal, mid-to-apical, mid-, and apical IVPG were significant (P< 0.0001) predictors of chronic CHF following MI.
Conclusion
Compared to the structural, and functional indices of conventional echocardiography, IVPG derived from CMME could provide a substantial non-invasive tool to diagnose and predict CHF after long-term MI.

Male urethral diverticula with calculi have a low incidence. It is extremely rare when the diverticulum accompanied with carcinoma. We report a case of diverticulum of the male urethra containing giant calculi which developed into squamous cell carcinoma. The patient initially presented with lower urinary tract symptoms and a hard, painless perineal mass. We believe that the process of diagnosis and treatment is of great significance in clinical practice.

Abstract
Objective: To examine the safety and complications of two methods of establishing retroperitoneal cavity in urology. Methods: Totally 83 patients undergoing retroperitoneal laparoscopic surgery in Department of Urology, Shanxi Bethune Hospital from January 2020 to June 2021 were analyzed retrospectively. There were 47 males and 36 females, aged (48.3±11.3) years (range: 35 to 71 years). Forty-three cases in Hasson group(the first Trocar channel was selected at the junction of the 12th rib and the posterior axillary line or lumbar triangle), 40 cases in modified Hasson group(the first Trocar channel is selected at 1.5 cm above the iliac crest on the mid-axillary line). The t test, χ² test, and Fisher exact test were used to compare the surgical safety indicators and complications of the two groups of patients. Results: There was no statistical difference between the two groups in gender, age, body mass index, waist length, and height (P>0.05). The comparison of safety indicators, included the time from skin incision to establishment of the retroperitoneal cavity and the amount of bleeding from the cavity were statistical difference between the two groups (P<0.05). Compared to that in Hasson group, the time from skin incision to establishment of the abdominal cavity in modified Hasson group was shorter ((8.56±2.64) minutes vs. (5.32±1.36) minutes, t=6.949, P<0.01), the blood loss of establishment was less ((15.32±6.09) ml vs. (9.85±3.55) ml, t=4.951, P<0.01). In terms of complication indicators, the incidence of Trocar hernia and the number of subcutaneous emphysema in modified Hasson group were lower than that in Hasson group (20.9% (9/43) vs. 2.5% (1/40), P=0.015, 18.6% (8/43) vs. 2.5% (1/40), P=0.030). Conclusions: The modified Hasson group is a safe method of establishing retroperitoneal cavity. The technique is simple and fast. It provides urologists with a more effective and easy-to-implement option with fewer complications.

Abstract
Objective: To investigate the clinical features and prognostic influencing factors of toxic epidermal necrolysis (TEN). Methods: A retrospective observational study was conducted. From January 2008 to March 2019, a total of 46 TEN patients who met the inclusion criteria were admitted to Guangdong Provincial People's Hospital. The gender, age, and hospital admission diagnosis of the 46 patients, the category of department admitted of patients complicated with sepsis, death ratio of the sepsis patients with or without treatment history in intensive care unit (ICU)/department of burns and wound repair, and the cause of death of the deceased patients were recorded. Depending on whether complicated with sepsis, the patients were divided into sepsis group (32 cases) and non-sepsis group (14 cases). According to whether died or not, the patients were divided into death group (9 cases) and survival group (37 cases). The specific conditions of suspected pathogenic agents and combined underlying diseases, the abnormality of transaminase/bilirubin, creatinine, and platelet count in blood on admission, and the detection of pathogenic microorganisms and drug resistance during the course of disease of patients were recorded in both sepsis group and non-sepsis group. The gender, age, lesion area, severity of illness score for TEN (SCORTEN) system score, combined underlying diseases on admission, and blood microbial culture positivity, hormone use, and gamma globulin use during the course of disease of patients between sepsis group and non-sepsis group, death group and survival group were compared respectively. Data were statistically analyzed with chi-square test, Fisher's exact probability test, and Mann-Whitney U test. The factors with statistically significant differences between sepsis group and non-sepsis group, death group and survival group were selected for binary multivariate logistic regression analysis, so as to screen the independent risk factors affecting sepsis and death in TEN patients. Results: Of the 46 TEN patients, 30 were male and 16 were female, aged from 8 months to 92.0 years, with 11 cases (23.91%) of epidermolysis bullosa, 9 cases (19.57%) of exfoliative dermatitis, 9 cases (19.57%) of TEN, 7 cases (15.22%) of epidermolysis bullosa, 6 cases (13.04%) of Stevens-Johnson syndrome, and 4 cases (8.70%) of severe drug rash for hospital admission diagnosis. The patients complicated with sepsis were admitted to 11 departments, and the death ratio of patients with treatment history in ICU/department of burns and wound repair was similar to that of patients without such department treatment history (P>0.05). All the deceased patients were complicated with sepsis, which was also the main cause of death. On admission, the suspected pathogenic agents of patients in sepsis group were mainly allopurinol (8 cases) and non-steroidal anti-inflammatory drugs (4 cases), while those in non-sepsis group were allopurinol (3 cases) and psychotropic drugs (3 cases). Patients in sepsis group combined as many as 10 underlying diseases, while those in non-sepsis group combined only 4 underlying diseases. The proportions of patients with increased creatinine (χ2=13.349, P<0.01) and decreased platelet count (P<0.01) in sepsis group were significantly higher than those in non-sepsis group, while the transaminase/bilirubin abnormality was similar to that in non-sepsis group (P>0.05). A wide variety of pathogens were detected in the blood, respiratory tract secretions, and skin secretions of 21 patients in sepsis group, and 14 patients were infected with drug-resistant bacteria; among the 9 strains cultured from the blood samples, 8 were drug-resistant bacteria and 6 were Gram-positive bacteria. In non-sepsis group, pathogens were detected in blood, respiratory tract secretions, and skin secretions of 8 patients, with fewer species, and 6 patients were infected with drug-resistant bacteria. The gender, age, lesion area, blood microbial culture positivity, hormone use, and gamma globulin use of patients in sepsis group were similar to those in non-sepsis group (P>0.05). The proportion of patients combined with underlying diseases (χ2=4.493, P<0.05) and the proportion of patients with SCORTEN system score of 4-6 points (P<0.01) of patients in sepsis group were significantly higher than those in non-sepsis group. The gender, combined underlying diseases, lesion area, blood microbial culture positivity, hormone use, and gamma globulin use of patients were similar between survival group and death group (P>0.05). The proportion of patients with age≥60 years and the proportion of patients with SCORTEN system score of 4-6 points of patients in death group were significantly higher than those in survival group (χ2=4.412, 11.627, P<0.05 or P<0.01). The SCORTEN system score was an independent risk factor affecting sepsis and death in TEN patients (odds ratio=3.025, 2.757, 95% confidence interval=1.352-6.769, 1.244-6.110, P<0.05 or P<0.01). Conclusions: The diagnosis of TEN is difficult on admission. Male population is susceptible to TEN, and allopurinol is the common pathogenic agent. The proportion of patients combined with underlying diseases is high in TEN patients complicated with sepsis, with mainly drug-resistant bacteria and mostly Gram-positive bacteria in blood-borne infections. The deceased patients are older than the survived, and the main cause of death is sepsis. The SCORTEN system score is an independent risk factor affecting sepsis and death in TEN patients.

Abstract
Objective: Transanal total mesorectal excision (taTME) was a very hot topic in the first few years since its appearance, but now more introspections and controversies on this procedure have emerged. One of the reasons why the Norwegian Ministry of Health stopped taTME was the high incidence of postoperative anastomotic leak. In current study, the incidence and risk factors of anastomotic leak after taTME were analyzed based on the data registered in the Chinese taTME Registry Collaborative (CTRC). Methods: A case-control study was carried out. Between November 15, 2017 and December 31, 2020, clinical data of 1668 patients undergoing taTME procedure registered in the CTRC database from 43 domestic centers were collected retrospectively. After excluding 98 cases without anastomosis and 109 cases without complete postoperative complication data, 1461 patients were finally enrolled for analysis. There were 1036 males (70.9%) and 425 females (29.1%) with mean age of (58.2±15.6) years and mean body mass index of (23.6±3.8) kg/m(2). Anastomotic leak was diagnosed and classified according to the International Study Group of Rectal Cancer (ISREC) criteria. The risk factors associated with postoperative anastomotic leak cases were analyzed. The impact of the cumulative number of taTME surgeries in a single center on the incidence of anastomotic leak was evaluated. As for those centers with the number of taTME surgery ≥ 40 cases, incidence of anastomic leak between 20 cases of taTME surgery in the early and later phases was compared. Results: Of 1461 patients undergoing taTME, 103(7.0%) developed anastomotic leak, including 71 (68.9%) males and 32 (31.1%) females with mean age of (59.0±13.9) years and mean body mass index of (24.5±5.7) kg/m(2). The mean distance between anastomosis site and anal verge was (2.6±1.4) cm. Thirty-nine cases (37.9%) were classified as ISREC grade A, 30 cases (29.1%) as grade B and 34 cases (33.0%) as grade C. Anastomotic leak occurred in 89 cases (7.0%,89/1263) in the laparoscopic taTME group and 14 cases (7.1%, 14/198) in the pure taTME group. Multivariate analysis showed that hand-sewn anastomosis (P=0.004) and the absence of defunctioning stoma (P=0.013) were independently associated with anastomotic leak after taTME. In the 16 centers (37.2%) which performed ≥ 30 taTME surgeries with cumulative number of 1317 taTME surgeries, 86 cases developed anastomotic leak (6.5%, 86/1317). And in the 27 centers which performed less than 30 taTME surgeries with cumulative number of 144 taTME surgeries, 17 cases developed anastomotic leak (11.8%, 17/144). There was significant difference between two kinds of center (χ(2)=5.513, P=0.019). Thirteen centers performed ≥ 40 taTME surgeries. In the early phase (the first 20 cases in each center), 29 cases (11.2%, 29/260) developed anastomotic leak, and in the later phase, 12 cases (4.6%, 12/260) developed anastomotic leak. The difference between the early phase and the later phase was statistically significant (χ(2)=7.652, P=0.006). Conclusion: The incidence of anastomotic leak after taTME may be reduced by using stapler and defunctioning stoma, or by accumulating experience.

Abstract
INTRODUCTION Exposure to environmental pollutants such as diesel exhaust particles (DEP) increases the risk of asthma and asthma exacerbation. However, the exact mechanisms inducing asthma to low doses of allergens remain poorly understood. The present study aimed to analyse the immunomodulatory effect of the inhalation of DEP in a mouse model exposed to non-asthmagenic doses of soybean hull extract (SHE). MATERIAL AND METHODS BALB/c ByJ mice were randomly divided into four experimental groups. Two groups received nasal instillations of saline and the other two groups received 3 mg ml-1 SHE during 5 days per week for 3 weeks. One group in each pair also received 150 μg of DEP in the same instillations 3 days per week. SHE-specific IgE levels, oxidative stress, leukocyte pattern and optical projection tomography (OPT) imaging studies were assessed. RESULTS Inhalation of SHE and/or DEP increased levels of H2O2 in BAL, while coexposure to SHE and DEP increased SHE-specific IgE levels in serum. Inhalation of SHE alone increased eosinophils, B cells, total and resident monocytes and decreased levels of NK cells, while inhalation of DEP increased neutrophils and decreased total monocytes. Regarding dendritic cells (DC), the inhalation of SHE and/or DEP increased the total population, while the inhalation of SHE alone increased Th2-related DCs (CD11b + Ly6C-) and decreased tolerogenic DCs (CD11b-Ly6C-). However, coexposure to SHE and DEP increased oxidative stress-sensitive DCs (CD11b-Ly6C+) and decreased Th1-related DCs (CD11b + Ly6C+). As regards macrophages, inhalation of SHE and DEP decreased total and alveolar populations. DEP deposition in lung tissue did not differ between groups. CONCLUSION Coexposure to DEP activates the asthmatic response to low doses of soy by triggering the immune response and oxidative stress.

Abstract
Objectives: Despite recent advances in the treatment of rheumatoid arthritis (RA), few population-based studies have assessed the mortality rates and the underlying causes of death (UCDs) among patients with RA and RA-associated interstitial lung disease (RA-ILD). This study evaluated the trends in mortality rates, demographic characteristics, and UCDs among patients with RA-ILD.Method: Using data from death certificates (1999-2018) from the US Centers for Disease Control and Prevention Multiple Cause of Death files, we explored the trends in mortality rates and UCD for patients with RA and RA-ILD. Moreover, we examined the crude and age-standardized mortality rates (ASMRs) for such patients.Results: Among patients with RA or RA-ILD, ASMR variation decreased over 20 years. The ASMR ratio of RA-ILD to RA decreased by 5.84%. The ASMR for RA and RA-ILD stratified by gender or age group also decreased. The change in the ASMR ratio of RA-ILD to RA trended downwards in women and upwards in men. Arthropathies and ILD were the most frequent UCDs for RA-ILD, while arthropathies and ischaemic heart disease were the most frequent UCDs for RA.Conclusions: Although RA and RA-ILD presented a downward trend in mortality, RA combined with ILD may reduce life expectancy. Specifically, the mortality rate for patients with RA-ILD remained relatively stable during the study period when ILD was the UCD, suggesting the need for active prevention, early diagnosis, and effective management of RA-ILD.

Abstract
AIM Biomechanical stress plays an essential role in coronary atherosclerosis (CAS), however, inter-relations between mechanical conditions and gene expressions remain unclear. METHODS We constructed finite element model of CAS to map human wall shear stress (WSS). Biopsy aortic tissue samples were obtained from 3 CAS patients. Gene expression pattern in CAS was analyzed by GEO datasets. Immunofluorescence staining and western blot confirmed protein expression and localization. RESULTS Peak WSS was significantly increased in the vessel stenosis of CAS at 0.25 s (mean 55.1 Pa). Analyses results of GSE76275 showed matrix metalloproteinases1 (MMP1) and phosphodiesterase-2A (PDE2A) up-regulation in endothelial shear responsiveness, which was further validated and localized in vascular endothelial cells, smooth muscle cells and other cells by double immunofluorescence staining. Western blotting assay demonstrated up-regulation of MMP1 and PDE2A expression dependent on the WSS. CONCLUSIONS MMP1 and PDE2A up-regulations rely on increased WSS in development and risk of CAS, suggesting that their elevation may be potential target for diagnosis and treatment (Fig. 3, Ref. 28).

Abstract
OBJECTIVE To investigate the effects of ET-1 and TNF-α levels on cardiac function and prognosis in rats with chronic heart failure (CHF), to provide reference for clinical practice. MATERIALS AND METHODS 120 SD rats were randomly divided into healthy group (n=60) and heart failure group (n=60). Rats from heart failure group were made into CHF models by an intraperitoneal injection of adriamycin. According to the average serum levels of ET-1 and TNF-α, 30 rats with higher level were enrolled in high expression subgroup, while 30 rats with lower level were enrolled in low expression subgroup. The sandwich enzyme-linked immunosorbent assay (ELISA) was employed to determine the ET-1 and TNF-α in rats from healthy group and heart failure group. Doppler echocardiography was used to measure the left ventricular ejection fraction, heart rate, and aortic diameter. After the death of heart failure rats, the total heart mass and left ventricle mass were measured and compared with those of the healthy rats. The serum levels of ET-1 and TNF-α were monitored to explore the influence of ET-1 and TNF-α levels on the prognosis of rats from study group. RESULTS The total heart mass and left ventricle mass of the heart failure group were higher than those of healthy group (p<0.05). The total heart mass and left ventricle mass of the low expression subgroup were lower than those of high expression subgroup (p<0.05). CONCLUSIONS The serum levels of ET-1 and TNF-α are higher than those in healthy rats. CHF rats with higher serum levels of ET-1 and TNF-α have a worse heart function and survival. Serum levels of ET-1 and TNF-α can be used as predictors of cardiac function and prognosis in CHF rats, providing references for clinical practice.

Abstract
Microtubules (MT) are critical cytoskeletal filaments that have several functions in cell morphogenesis, cell division, vesicle transport and cytoplasmic separation in the spatiotemporal regulation of eukaryotic cells. Formation of MT requires the co-interaction of MT nucleation and α-β-tubulins, as well as MT-associated proteins (MAP). Many key MAP contributing to MT nucleation and elongation are essential for MT nucleation and regulation of MT dynamics, and are conserved in the plant kingdom. Therefore, the deletion or decrease of γ-tubulin ring complex (γTuRC) components and related MAP, such as the augmin complex, NEDD1, MZT1, EB1, MAP65, etc., in Arabidopsis thaliana results in MT organizational defects in the spindle and phragmoplast MT, as well as in chromosome defects. In addition, similar defects in MT organization and chromosome structure have been observed in plants under abiotic stress conditions, such as under high UV-B radiation. The MT can sense the signal from UV-B radiation, resulting in abnormal MT arrangement. Further studies are required to determine whether the abnormal chromosomes induced by UV-B radiation can be attributed to the involvement of abnormal MT arrays in chromosome migration after DNA damage.
