ABSTRACT
Objective: To discuss the value of amplified in breast cancer 1(AIB1) and androgen receptor (AR) for the resistance of adjuvant tamoxifen in estradiol receptor (ER) positive breast cancer. Methods: A total of 188 cases with breast cancer after receiving tamoxifen treatment in the Tianjin Medical University Cancer Institute and Hospital from June 2008 to July 2013 were enrolled in this study.Using immunohistochemical SP method to detect AIB1and AR expression in breast cancer tissue, analyzing the relationship of AIB1 and AR expression and the effect of tamoxifen.And verify the results of the experiment through the GEPIA database. Results: The response of tamoxifen was 80.3%. The response rate in AR positive group and AR negative group was 79.6% and 82.4%, with no significant difference (P=0.669). The response rate in AIB1 High expression group and AIB1 Low expression group was 68.4% and 93.3%, respectively, with a significant difference (P<0.001).The response rate in AR negative and AIB1 Low expression group, AR negative and AIB1 High expression group, AR positive and AIB1 Low expression group, AR positive and AIB1High expression group was 89.7%, 71.4%, 96.7%, 66.2%respectively, with a significant difference (P<0.001). Conclusions: The expression level of AIB1 is correlated with the therapeutic effect of tamoxifen in breast cancer. Its high expression can cause tamoxifen resistance, while AR positive and High expression of AIB1 are more likely to cause tamoxifen resistance, and AIB1 can be used as an independent influencing factor for breast cancer tamoxifentreatment.

Objective: To assess the effect of jejunal feeding tube placement on early complications of laparoscopic radical gastrectomy in patients with incomplete pyloric obstruction by gastric cancer. Methods: This was a retrospective cohort study. Perioperative clinical data of 151 patients with gastric antrum cancer complicated by incomplete pyloric obstruction who had undergone laparoscopic distal radical gastrectomy from May 2020 to May 2022 in the First Affiliated Hospital of Nanchang University were collected. Intraoperative jejunal feeding tubes had been inserted in 69 patients (nutrition tube group) and not in the remaining 82 patients (conventional group). There were no statistically significant differences in baseline characteristics between the two groups (all P>0.05). The operating time, intraoperative bleeding, time to first intake of solid food, time to passing first flatus, time to drainage tube removal, and postoperative hospital stay, and early postoperative complications (occurded within 30 days after surgery) were compared between the two groups. Results: Patients in both groups completed the surgery successfully and there were no deaths in the perioperative period. The operative time was longer in the nutritional tube group than in the conventional group [(209.2±4.7) minutes vs. (188.5±5.7) minutes, t=2.737, P=0.007], whereas the time to first postoperative intake of food [(2.7±0.1) days vs. (4.1±0.4) days, t=3.535, P<0.001], time to passing first flatus [(2.3±0.1) days vs. (2.8±0.1) days, t=3.999, P<0.001], time to drainage tube removal [(6.3±0.2) days vs. (6.9±0.2) days, t=2.123, P=0.035], and postoperative hospital stay [(7.8±0.2) days vs. (9.7±0.5) days, t=3.282, P=0.001] were shorter in the nutritional tube group than in the conventional group. There was no significant difference between the two groups in intraoperative bleeding [(101.1±9.0) mL vs. (111.4±8.7) mL, t=0.826, P=0.410]. The overall incidence of short-term postoperative complications was 16.6% (25/151). Postoperative complications did not differ significantly between the two groups (all P>0.05). Conclusion: It is safe and feasible to insert a jejunal feeding tube in patients with incomplete outlet obstruction by gastric antrum cancer during laparoscopic radical gastrectomy. Such tubes confer some advantages in postoperative recovery.

OBJECTIVE: To investigate the prevalence and influencing factors of Blastocystis hominis infection among children with diarrhea under five years of age in Guangzhou City. METHODS: Children with diarrhea under 5 years of age admitted to Guangzhou Children's hospital, Guangzhou Maternity and Child Healthcare Hospital and Guangzhou Women and Children's Medical Center during the period between January 1 and December 31, 2020, were enrolled. Participants' demographics, living environments and health status were collected using questionnaire surveys. Stool samples were collected from participants and nucleic acid was extracted. B. hominis infection was identified using PCR assay and sequence alignment, and the factors affecting B. hominis infection among children with diarrhea under 5 years of age were identified using univariate analysis and multivariate logistic regression analysis. RESULTS: A total of 684 children with diarrhea under 5 years of age were enrolled, including 468 male children and 216 female children, with a mean age of (1.79 ± 1.12) years. The overall prevalence of B. hominis infection was 4.97% [34/684, 95% confidential interval (CI): (3.59%, 6.86%)] among participants, and there was no significant difference in the prevalence of B. hominis infection between children with chronic [7.52% (20/266), 95% CI: (4.92%, 11.33%)] and acute diarrhea [3.35% (14/418), 95% CI: (2.01%, 5.54%)] (χ2 = 5.983, P = 0.014). Multivariate logistic regression analysis identified keeping pet [odds ratio (OR) = 6.298, 95% CI: (2.711, 14.633)], drinking non-tap water [OR = 4.522, 95% CI: (1.769, 11.561)], lactose intolerance [OR = 4.221, 95% CI: (1.043, 17.087)], antibiotic use [OR = 0.125, 95% CI: (0.017, 0.944)] and chronic diarrhea [OR = 2.172, 95% CI: (1.018, 4.637)] as factors affecting B. hominis infection among children with diarrhea under 5 years of age in Guangzhou City. CONCLUSIONS: B. hominis infections is detected in children with diarrhea under five years of age in Guangzhou City. Improving home environments and pet-keeping hygiene is recommended to reduce the likelihood of B. hominis infection among children.

OBJECTIVE: The aim of this study was to explore the association between TP53 gene polymorphisms (rs8068934 A>G and rs218698 C>T) and chronic lymphocytic leukemia (CLL). PATIENTS AND METHODS: CLL patients who received treatment in our hospital were enrolled in this study as the disease group. Meanwhile, healthy subjects were taken as the control group. Peripheral blood samples were collected to detect TP53 gene polymorphisms at rs8068934 and rs218698, and the haplotype analysis was performed. The expression of TP53 was detected via reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Furthermore, the survival conditions were analyzed. RESULTS: The allele distribution at rs8068934 (p=0.046) and rs218698 (p=0.028) of TP53 gene was different between control group and disease group. A allele frequency at rs8068934 and T allele frequency at rs218698 were significantly higher in disease group (p<0.05). The genotype distribution at rs218698 of TP53 gene in disease group was also different from that in control group (p=0.038). The results demonstrated that CC genotype frequency in disease group was significantly lower than that in control group (p<0.05). Besides, the distribution of dominant model at rs8068934 (p=0.042) and recessive model at rs218698 (p=0.033) in disease group exhibited remarkable differences from control group, in which AA+AG frequency (dominant model) at rs8068934 and CC+CT frequency (recessive model) at rs218698 in disease group were significantly higher. Meanwhile, the distribution of AT (p=0.029) and GC (p=0.007) haplotypes at rs8068934 and rs218698 in disease group was evidently different from that in control group. The results indicated that disease group showed significantly higher frequency of AT haplotype and lower frequency of GC haplotype (p<0.05). Moreover, TP53 gene polymorphisms at rs8068934 were significantly associated with the levels of white blood cells (WBC) (p=0.000) and platelets (PLT) (p=0.035). Patients with GG genotype had significantly higher level of WBC, while those with AG genotype showed significantly lower level of PLT (p<0.05). TP53 gene polymorphisms at rs218698 were associated with the level of red blood cells (RBC) (p=0.000). Patients with CT genotype had a remarkably lower level of RBC (p<0.05). There were significant correlations of TP53 gene polymorphisms at rs8068934 (p=0.000) and rs218698 (p=0.000) with the expression of TP53. The expression of TP53 was lower in people with AA genotype at rs8068934 but higher in people with TT genotype at rs218698 (p<0.05). Furthermore, TP53 gene polymorphisms at rs8068934 (p=0.000) and rs218698 (p=0.000) were markedly associated with patients' survival. CONCLUSIONS: TP53 polymorphisms are significantly correlated with the occurrence and progression of CLL.

Objective: To evaluate the efficacy and safety of Oryz-Aspergillus enzyme and pancreatin tablets (Combizym(®)) in the treatment of postprandial distress syndrome (PDS) in the elderly, compared with gastrointestinal motility drugs. Methods: A prospective randomized controlled trial was designed and registered in the China Clinical Trials Registry (ChiCTR-IPR-16008185). The elderly patients with PDS were randomly divided into three groups, including Mosapride group with Mosapride citrate tablets 5 mg 3 times per day for 2 weeks; Combizym(®) group with Combizym tablets 244 mg 3 times per day for 2 weeks; combined treatment group with both drugs and same doses for 2 weeks. The modified Nepean dyspepsia index (NDSI) score, discomfort intensity score and PDS score were calculated on patients before treatment, at the end of first and second week of treatment, as well as 4 weeks after treatment finished, respectively. Adverse effects were evaluated. Results: A total of 323 patients from 16 tertiary hospitals in China were enrolled in this study. Among them, 105 patients were in Mosapride group, 109 in Combizym(®) group and 109 in combined treatment group. There were 148 males (45.8%) and 175 females (54.2%) with median age 71.4±9.0 years (60-100 years). Baseline characteristics of three groups were comparable. After treatment, the NDSI scores in three groups all decreased significantly (P<0.001), while they were similar between groups (P>0.05). The discomfort intensity score and PDS score in three groups showed a significant reduction after treatment (P<0.001), especially in the combined treatment group. Compared with Mosapride group, the scores in Combizym(®) group decreased significantly after one or two weeks [discomfort intensity score: after one week, 4.0(2.5, 8.0) vs. 6.0(3.0, 10.0); after two weeks, 3.0(0.0, 5.0) vs. 4.0(2.0, 6.0); all P<0.05. PDS score: after one week, 6.0(3.0, 9.0) vs. 7.0(3.5, 10.5); after two weeks, 3.0(0.0, 5.0) vs. 4.0(2.0, 7.0); all P<0.05]. The efficacy rate in all patients after first week of treatment was over 15.0%. The efficacy rates after two weeks were 55.2%, 68.8% and 73.4% in Mosapride group, Combizym(®) group and combined treatment group, respectively. After two week treatment, the efficacy rates in Combizym(®) group (P=0.041) and combined group (P=0.006) were higher than that of Mosapride group. The recurrence rate of Mosapride group was 9.5%, which was significantly higher than that of Combizym(®) group (1.8%, P<0.05) and combined treatment group (1.8%, P<0.05). There were no serious adverse effects in the three groups. Conclusions: The efficacy of Oryz-Aspergillus enzyme and pancreatin tablets is comparable with that of Mosapride in elderly PDS patients, with fewer adverse effects and low recurrence rate. Combination regimen indicates better efficacy than that of Oryz-Aspergillus enzyme and pancreatin tablets or Mosapride alone.

OBJECTIVE: This study aimed to investigate the expression of miR-373 in osteoporosis patients and rat models induced by estrogen deficiency and to detect whether miR-373 can regulate the ability of osteogenic differentiation of bone marrow mesenchymal stem cells in the osteoporosis microenvironment caused by estrogen deficiency. PATIENTS AND METHODS: Bone tissues and blood samples were collected from 20 osteoporotic patients and 20 controls. PCR analysis was used to detect the expression of miR-373 in bone tissue and serum from postmenopausal osteoporotic patients and normal patients. 120 SD rats were purchased and randomly divided into sham operation group and OVX group. Rat models of sham-operated and bilateral oophorectomy mice models were constructed. The expression of miR-373 in bone tissue, cells, and serum of the mice was tested. Then, bone marrow mesenchymal stem cells from sham-operated rats and bilaterally ovariectomized rats were isolated and cultured. After 10 days of osteogenic induction, alkaline phosphatase staining and alizarin red staining were performed to test the osteogenic differentiation ability of bone marrow mesenchymal stem cells, and whether miR-373 affects this ability. RESULTS: PCR results showed that the expression of miR-373 in the bone tissue and the serum of patients with postmenopausal osteoporosis was significantly reduced. The expression of miR-373 was markedly decreased in the bone tissue, cells, and serum from the rats of bilateral ovariectomy group. Alkaline phosphatase staining and alizarin red staining showed that miR-373 could promote the differentiation of bone marrow mesenchymal stem cells into osteoblasts and reverse the decreased osteogenic differentiation of bone marrow mesenchymal stem cells caused by osteoporosis. CONCLUSIONS: The expression of miR-373 is decreased in osteoporotic patients and rat models caused by estrogen deficiency, and it can promote the differentiation of bone marrow mesenchymal stem cells into the osteogenic direction. This work provides a new direction and experimental basis for clinical diagnosis and treatment of osteoporosis.

Objective: To explore the indications and safety of orthopedic liver transplantation for polycystic liver disease (PLD). Methods: Data of 11 patients with PLD who underwent orthotopic liver transplantation between 2004 and 2013 was retrospectively analyzed. Demographic, clinical and follow-up data were collected for statistical analysis. The survival rate was calculated by Kaplan-Meier method. Results: Over a period of 10 years, the patients received modified piggyback orthopedic liver transplantation (n=9) or combined liver-kidney transplantation (n=2) for PLD. The recipients' median age was 56 years. Seven patients were classified as Gigot type â ¡ PLD, and four were classified as Gigot type â ¢ PLD. Eight patients had severe decreased mobility (Eastern Cooperative Oncology Group, ECOG≥3). Only three cases were Child-Pguh Class C patients and the model for end-stage liver disease (MELD) score was>20. The mean hospitalization duration was (45.4±15.3) days, and the mean length of stay in intensive care unit was (4.1±1.9) days. The perioperative mortality was 18.2% and morbidity of complications was 63.6%. The median follow-up period was 111 months. Two patients died of severe complications after combined liver-kidney transplantation. One patient died of ischemia cholangitis during follow-up. The actuarial 1-, 5-and 10-year survival rate during the follow-up period was 82.2%, 81.8%, and 65.5%, respectively. Conclusions: Liver transplantation is the only curative and safe procedure for PLD, and it provides a good long-term prognosis and high quality of life for PLD patients. Liver transplantation could be a primary option in treating progressive or advanced PLD.

Objective: To explore the function and role of innate lymphoid cells in the pathogenesis of systemic lupus erythematosus (SLE) at different disease activity levels. Methods: From Nov 2017 to May 2018, 40 patients with SLE and 15 age-matched healthy non-immune-related diseases controls were enrolled from Anhui provincial hospital. According to the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI)-2K, the patients were divided into active group (n=20) and remission group (n=20). The frequency of ILCs, B cells, CD4+T and CD8+T cells from peripheral blood mononuclear cells (PBMCs) was detected by flow cytometry. The subsets of ILCs in each group were compared with the subsets of B cells and T cell respectively. The levels of IL-4, IL-33 and IFN-γ in each group were tested by ELISA. Result: Compared with the control group, ILC1 percentage was significantly increased in SLE active group [(22.33%±2.52%) vs (14.56%±1.28%), P=0.018 1]; ILC2 percentage was decreased significantly in both remission group [(19.67%±1.83%) vs (42.48%±3.46%), P<0.000 1] and active group [(8.67%±0.83%) vs (19.67%±1.83%), P<0.000 1]; ILC3 percentage was decreased significantly in active group [(5.72%±1.08%) vs (14.35%±2.40%), P=0.001 3]. SLEDAI score was negatively correlated with the percentage of ILC2 (P=0.023 9) in all patients. The percentage of ILCs in the remission group (P=0.046 2) and activity group (P=0.003 7) were both increased significantly. Moreover, the percentage of ILC2 in active group was negatively correlated with CD4+T cells (P=0.030 8), and the serum IgG was negatively correlated with ILC2% in all patients (P=0.013 8). Compared with control group or remission group, the levels of IFN-γ (F=10.91, P=0.000 1) and IL-4 (F=6.046, P=0.004 7) in active group were remarkable higher. However, IL-33 was significantly reduced in active group (F=6.645, P=0.002 7). The percentage of ILC2 (r=0.154 3, P=0.028 8) and ILC3 (r=0.313 6, P=0.001 1) in all patients with SLE were positively correlated with the level of IL-4. Conclusion: The percentage of ILCs is related to disease activity, and ILCs play a "double-edged" role in the pathogenesis of SLE. Its function and mechanism are worth further exploration.

Aberrantly overexpressed oncogenic microRNAs (miRNAs, miRs) are excellent targets for therapeutic interventions. Nevertheless, thus far, little progress has been made in developing miRNA-based drugs and techniques for clinical applications, especially for overexpressed miRNAs. In this study, we demonstrate that self-assembled DNA nanostructures bearing multiple DNA sequences that are complementary to a target miRNA can effectively capture the overexpressed oncogenic miRNA and subsequently inhibit cancer cell proliferation. Specifically, a DNA nanotube structure that carries functional DNA segments (single-stranded, duplex and hairpin forms) was designed and synthesized to capture two well-known overexpressed miRNAs, miR-21 and miR-155. It was found that all three DNA nanotubes significantly reduced both miRNA levels and inhibited cancer cell growth. Moreover, the capture efficiency was highly concentration dependent and was associated with the structural design of the DNA nanotube. These results demonstrate that through careful design, programmable DNA nanostructures can hijack the natural cellular machinery and can serve as nucleic acid drugs themselves. The concept of using self-assembled DNA nanostructures to disrupt the intracellular machinery for therapeutic purposes opens a new paradigm for exploiting self-assembled DNA nanostructures for miRNA-based anticancer therapy.
ABSTRACT
The present work has systematically investigated the evolution of dispersoids and elevated-temperature properties including strength and creep resistance during various multi-step heat treatments in Al-Mn-Mg 3004 alloys. Results show that only the α-Al(MnFe)Si dispersoid is observed in the studied temperature range (up to 625 °C), and that it coarsens with increasing temperature to 500 °C, but dissolves at 625 °C. The evolution of elevated-temperature strength and creep resistance is greatly related to the temperature of each step during the multi-step heat treatments. Generally, lower temperature at the first-step heat treatment leads to higher properties, while the properties decrease with increasing temperature of last-step heat treatment. Suitable models have been introduced to explain the evolution of strength and the creep threshold stress at elevated-temperatures during the various heat treatments.
ABSTRACT
To investigate the accuracy and feasibility of Brix value on monitoring gastric residual volume (GRV) in patients with enteral nutrition. Fifty patients with enteral nutrition via nasogastric tube were enrolled. The GRV was measured by both ultrasonography and Brix value. The results were compared according to the methods. The Pearson correlation coefficients showed that GRV measured by these two ways was positively correlated (r=0.986, P<0.05). Moreover paired sample t-test showed that the discrepancy was not statistically significant (P>0.05) between different measurements. The consistency was analyzed by Bland-Altman graph, showing that the two measurements were consistent. Brix value is recommended to measure GRV due to its convenience and easy operation.

Objective: To evaluate the feasibility of detecting index of microcirculatory resistance (IMR) and the relationship between IMR and left ventricular (LV) systolic function after acute myocardial infarction (AMI) undergoing primary percutaneous coronary intervention (PCI). Methods: The patients with first AMI received primary PCI in Peking University Third Hospital were enrolled from January 2014 to March 2016. IMR were measured immediately after PCI by using pressure/temperature wire. The relationship between IMR and left ventricular ejection fraction (LVEF) assessed by echocardiography at first day and 6 months after admission was evaluated. Results: Twenty-eight patients with anterior wall AMI were enrolled, with an average age (56±13) years. The success rate of IMR detection was 100%. The mean IMR was (33±18 )mmHg·s. There was no complication related to intravenous adenosine triphosphate (ATP) (140 µg· kg(-1)· min(-1)). The IMR was negatively correlated with TIMI blood flow grade after primary PCI (r=-0.386, P=0.043), and positively correlated with female gender, CK peak value and TnT peak value (r=0.430, P=0.022; r=0.431, P=0.025; r=0.434, P=0.024). After 6 months of follow-up, no adverse cardiovascular events (including cardiac death, nonfatal myocardial infarction, malignant arrhythmia, unplanned revascularization, hospitalization for unstable angina pectoris and severe heart failure requiring hospitalization) occurred. LVEF increased significantly compared with the first day after PCI (0.54±0.08 vs 0.47±0.06, P=0.001), and IMR was negatively correlated with LVEF after 6 months (r=-0.477, P=0.014). Multivariable linear regression analysis showed that CK peak and IMR were predictors of LVEF after six months ( ß=-0.595, t=-3.814, P=0.01; ß=-0.352, t=-2.26, P=0.036). Conclusions: Immediate detection of IMR in patients with anterior wall AMI after PCI is safe and feasible. The immediate IMR after PCI reflects the extent of myocardial necrosis and myocardial perfusion, and is a predictor of LVEF at 6 months after PCI.

Objective: To investigate the effect of long-term low dose prednisone administration on bone mineral density (BMD) in patients with inactive systemic lupus erythematosus (SLE). Methods: A total of 118 inactive female SLE patients with long-term administration of low dose prednisone were recruited from the Department of Rheumatology and Immunology at An hui Provincial Hospital.All patients were given low dose prednisone for long-term (≤10 mg/d, more than half a year). According to prednisone doses, subjects were divided into two groups, namely group A (≤7.5 mg/d) and group B (7.5-10 mg/d). In addition, patients were also divided into four groups based on the duration of administration, including groupâ ≤3 years, â ¡from 4-5 years, â ¢ 6-10 years and â £>10 years.Twenty-nine healthy people were recruitedas normal controls.The BMD was measured by dual energy X-ray absorptiometry.The association of BMD with prednisone dose and duration was compared between different groups. Results: The incidence of osteopenia in all patients with SLE was 42.4%(50/118), and the incidence of osteoporosis was 14.4%(17/118). BMD of all bone sites in both group A and B were significantly lower than that in normal control group (P<0.05). Similarly, the BMD of all bone sites in groupâ , â ¡, â ¢ and â £ were significantly decreased (P<0.05). What needed to be stressed was the BMD in group â £ was lower than those in other three groups (P<0.05). Multiple logistic regression analysis showed that the cumulative prednisone dose was the risk factor for osteopenia, while taking calcium and alfacalcidol were protective factors. Conclusion: Long-term use of low dose prednisone result in the decrease of BMD in patients with inactive SLE.The lumbar spine and femoral neck had more severe osteopenia. Long-term administration of prednisone, even less than 7.5 mg/d, can also cause osteopenia.Calcium and alfacalcidol were protective factors of BMD.

As one of the top pork producers in China, Shandong Province suffered frequent outbreaks of porcine epidemic diarrhoea virus (PEDV) on pig farms from January 2012 to July 2015, resulting in significant economic losses. To better understand the prevalence situation, we conducted molecular epidemiological analyses of 38 PEDV strains isolated from 13 cities in Shandong Province. The detection rate of PEDV was 71.2% (146/205) by reverse transcription polymerase chain reaction (RT-PCR). The S genes of the 38 isolated samples were 4146 to 4161 nt in length and shared high levels of sequence identity (93.3-99.6% nt, 92.1-99.4% aa) with those of the 41 reference strains. Among the 38 strains, 31 strains that occupied 12 cities were classed into G3 genotype, while the other seven that only existed in four cities were classed into G2 genotype. In addition, the strains CH-SDLY-2-2014 and CH-SDLY-3-2014 isolated from Linyi were classed into the Gd subgenotype. Notably, there were multiple insertions or deletions in the S genes and several mutations in the neutralizing epitopes of the PEDV S protein. Overall, the results revealed that G2 and G3 are the predominant PEDV genotypes circulating in Shandong Province during 2012-2015, and Gd subgenotype in G3 group had already spread towards northern China in 2014.

OBJECTIVES: To explore the correlation between microRNA (miR)-200c and the severity of interstitial lung disease (ILD) associated with connective tissue diseases (CTDs). METHOD: We recruited 218 patients with CTDs who were evaluated with high-resolution computed tomography (HRCT) and the pulmonary function test (PFT). Peripheral blood mononuclear cells (PBMCs) were acquired from 23 patients with systemic sclerosis (SSc), 29 with dermatomyositis/polymyositis (DM/PM), 30 with primary Sjögren's syndrome (pSS), 47 with rheumatoid arthritis (RA), and 23 normal controls to detect the expression level of miR-200c by quantitative reverse transcription polymerase chain reaction (QRT-PCR). miR-200c levels were compared among the different disease groups, between the group with ILD (CTD+ILD) and the group without ILD (CTD-ILD), and between mild and severe ILD groups. Forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV1) were compared among the different CTD groups and the different CTD+ILD groups. RESULTS: The miR-200c level in the SSc group was significantly higher than in the DM/PM, pSS, and RA groups, and the levels in the DM/PM and pSS groups were significantly higher than in the RA group. The level of miR-200c in the CTD+ILD group was significantly higher than in the CTD-ILD group, and the level in the severe ILD group was significantly higher than in the mild ILD group. FVC and FEV1 were significantly different among the different CTD groups, and among the different CTD+ILD groups. There was a negative correlation between the level of miR-200c and FVC and FEV1. CONCLUSIONS: The level of miR-200c was positively correlated with the severity of ILD, and miR-200c in PBMCs could be a biomarker of the severity of ILD in CTDs.

AIM: Serum total bilirubin (STB), a protective cardiovascular factor, was retrospectively investigated to determine the relationship between STB levels and the severity of disease in Chinese patients with stable coronary artery disease (CAD). PATIENTS AND METHODS: A total of 347 eligible patients presenting to our department from December 2007 to December 2012 were divided into tertiles according to their Syntax scores (low, moderate, and high). To clarify the association between STB levels and major adverse cardiovascular events (MACE), all patients were divided into two groups according to the median baseline STB (greater than or less than 13.2 µmol/l), which was measured after at least 12-h fast. All participants were followed for a mean of 37.1 months for MACE, including all-cause death, recurrent nonfatal myocardial infarction, and recurrent percutaneous coronary intervention. RESULTS: The STB levels were significantly lower in the high Syntax score group than those of the other groups and were negatively correlated with the Syntax score and number of diseased vessels. Follow-up data showed a higher incidence of MACE in the low STB group compared with the high STB group. Elevated STB levels predict the long-term prognosis of patients with stable angina pectoris. Finally, Kaplan-Meier analysis showed a significantly higher event-free survival rate in the patients with high STB levels than those in the low STB group. CONCLUSIONS: STB levels were independently associated with the severity of disease in patients with stable CAD. Elevated STB is associated with cardiovascular events and may be useful as a biomarker of the severity and prognosis of stable CAD.

Although there have been many developments related to specific strategies for treating patients after poisoning exposures, the mainstay of therapy remains symptomatic and supportive care. One of the most aggressive supportive modalities is extracorporeal membrane oxygenation (ECMO). Our goal was to describe the use of ECMO for toxicological exposures reported to the American College of Medical Toxicology (ACMT) Toxicology Investigators Consortium (ToxIC). We performed a retrospective review of the ACMT ToxIC Registry from January 1, 2010 to December 31, 2013. Inclusion criteria included patients aged 0 to 89 years, evaluated between January 2010 through December 2013, and received ECMO for toxicological exposure. There were 26,271 exposures (60 % female) reported to the ToxIC Registry, 10 (0.0004 %) received ECMO: 4 pediatric (< 12 years), 2 adolescent (12-18 years), and 4 adults (>18 years). Time of initiation of ECMO ranged from 4 h to 4 days, with duration from 15 h to 12 days. Exposures included carbon monoxide/smoke inhalation (2), bitter almonds, methanol, and several medications including antihistamines (2), antipsychotic/antidepressant (2), cardiovascular drugs (2), analgesics (2), sedative/hypnotics (2), and antidiabetics (2). Four ECMO patients received cardiopulmonary resuscitation (CPR) during their hospital course, and the overall survival rate was 80 %. ECMO was rarely used for poisoning exposures in the ACMT ToxIC Registry. ECMO was utilized for a variety of ages and for pharmaceutical and non-pharmaceutical exposures. In most cases, ECMO was administered prior to cardiovascular failure, and survival rate was high. If available, ECMO may be a valid treatment modality.

The diagnosis of eosinophilic pneumonia (EP) is rare and challenging. This condition is frequently misdiagnosed as pulmonary tuberculosis, lymphoma, schistosomiasis, Wegener's granuloma, severe acute respiratory syndrome, or severe community-acquired pneumonia. Herein, we report a case in which computed tomography (CT)-guided percutaneous lung biopsy was used to diagnose EP without alveolar eosinophilia or peripheral eosinophilia. A roundworm identified in the patient's stool confirmed the precise diagnosis to be parasitic EP. This is, to our knowledge, the first reported case of EP confirmed by CT-guided percutaneous lung biopsy. CT-guided percutaneous lung biopsy may represent a new tool for the diagnosis of EP in patients without typical alveolar eosinophilia or peripheral eosinophilia.
