ABSTRACT

Objective:To investivate the relationship of serum estradiol and oxidative stress with microcirculation resistance in women with syndrome X.Methods:A total of 120 patients with syndrome X who were hospitalized in the Department of Cardiology in Guangzhou First People's Hospital from January 2015 to January 2019 were enrolled. All patients underwent coronary angiography and pressure wire examination and were divided into two groups according to the index of microcirculation resistance (IMR). Forty healthy people in the medical examination center were used as controls in the same period. The level of serum estradiol, interleukin-1 (IL-1), tumor necrosis factor-α (TNF-α), superoxide dismutase (SOD) were measured among three groups.Results:The rate of diabetes mellitus in high IMR group was higher than that in control group and low IMR group ( P<0.05). There was no significant difference between low IMR group and control group ( P>0.05). The levels of serum estradiol and SOD were significantly lower in high IMR group than those in low IMR group and control group. The levels of IL-1 and TNF-α were significantly higher in high IMR group than those in low IMR group and control group ( P<0.05). These indexes have the same relationship between low-IMR group and control group ( P<0.05). The level of serum estradiol was negatively correlated with the levels of IL-1 and TNF-α in high and low IMR groups and positively correlated with the level of SOD in these groups. Multivariate logistic regression analysis showed that diabetes, low serum estradiol level, low SOD level, high IL-1 level, high TNF-α level were the independent risk factors for microcirculation resistance in women with syndrome X ( P<0.05). Conclusions:The decreased serum estradiol is an important factor for coronary microcirculation disorders in women with syndrome X. The decrease of serum estradiol level leads to the loss of the corresponding antagonistic effect in oxidative stress state, which may be one of the important mechanisms of the formation and progress of coronary microcirculation disorder.

ABSTRACT

Objective:To explore the differences between emergency healthcare-associated pneumonia (HCAP) and community-acquired pneumonia (CAP), to analyze whether HCAP is a relatively independent type pneumonia in the emergency department in China.Methods:Clinical data of HCAP and CAP patients admitted to the emergency department of Beijing Tiantan Hospital, Beijing Chaoyang Hospital of Capital Medical University and Huilongguan Hospital from September 2018 to May 2019 were retrospectively analyzed. General information of the patients, types of basic diseases, laboratory examination within 24 h of admission, etiological examination results, empirical anti-infection treatment plan, mechanical ventilation and clinical outcome were collected. The pneumonia severity index (PSI) was used to assess the pneumonia severity. The measurement data were expressed as mean ± standard deviation for t test, and the counting data were performed by χ 2 test. A P<0.05 indicated statistical difference. Results:One hundred and five HCAP patients and 105 CAP patients were collected. The number of HCAP combined with two or more basic diseases was higher than that of the CAP group. There were statistically significant differences between the two groups in white blood cell count, mean hemoglobin and blood lactic acid level.The PSI score of the HCAP group was higher than that of the CAP group (134.0±26.3 vs 113.0±16.34). The PSI score grade IV of the HCAP group was lower than that of the CAP group, while the PSI score grade V of the HCAP group was higher than that of the CAP group, with statistically significant differences ( P<0.05). In the HCAP group, 73 strains (69.52%) and 55 strains (52.38%) of multi-drug resistant strains were isolated. Acinetobacter baumannii and Streptococcus pneumoniae, Klebsiella pneumoniae and Escherichia coli in the HCAP group were more than those in the CAP group. The drug resistance rate of pseudomonas aeruginosa to imipenem in the HCAP group was higher than that in the CAP group (22.2% vs 10.0%); the drug resistance rate of Acinetobacter baumannii to cefoperazone/sulbactam was lower than that in the CAP group (27.3% vs 54.5%); the drug resistance rate of Pseudomonas aeruginosa to Meropenem was lower than that in the CAP group (45.5% vs 72.7%). The proportion of carbapenems in the initial empirical anti-infection treatment in the HCAP group was higher than that in the CAP group (21.00% vs 10.48%), and the difference was statistically significant. The ratio of invasive mechanical ventilation and the fatality rate in the HCAP group were higher than those in the CAP group (21.00% vs 7.62%, 21.00% vs 8.57%; both P<0.05). Conclusions:HCAP patients in emergency department are complicated with a variety of basic diseases, high drug resistance rate of pathogenic bacteria, and more advanced drugs are required for initial empirical anti-infection treatment, high proportion of mechanical ventilation, and high fatality rate. HCAP is a relatively independent category of pneumonia in emergency in China.

ABSTRACT

Liver cirrhosis in China can be caused by many causes of which the most important one is chronic viral hepatitis. Hemorrhage and ascites were the main manifestations of decompensated liver cirrhosis, and the main cause of hemorrhage is viral hepatitis. The pathological basis of hemorrhage is portal hypertension and its secondary pathophysiological changes. Additionally, the deficiency of coagulation factors and the imbalance of coagulation and fibrinolysis both of which caused by the hypofunction of liver are also important reasons. This article reviews the mechanism of hemorrhage in decompensated liver cirrhosis in order to provide help for further research.

ABSTRACT

Background/Aims@#To determine the value of salivary pepsin in discriminating sub-types of gastroesophageal reflux disease (GERD) and GERD-related disorders. @*Methods@#Overall, 322 patients with different sub-types of GERD and 45 healthy controls (HC) were studied. All patients took Gastroesophageal Reflux Disease Questionnaire (GerdQ) and underwent endoscopy and 24-hour esophageal pH monitoring and manometry. Salivary pepsin concentration (SPC) was detected by using colloidal gold double-antibody immunological sandwich assay. Oral esomeprazole treatment was administrated in the patients with non-erosive reflux disease (NERD) and extra-esophageal symptoms (EES). @*Results@#Compared to HC, patients with erosive esophagitis, NERD, EES, EES plus typical GERD symptoms, or Barrett’s esophagus had a higher prevalence of saliva and SPC (all P < 0.001). There was no significant difference in the positive rate for pepsin in patients with functional heartburn or GERD with anxiety and depression, compared to HC. After esomeprazole treatment, the positive rate and SPC were significantly reduced in NERD (both P < 0.001) and in EES (P = 0.001 and P = 0.002, respectively). Of the 64 NERD patients, 71.9% (n = 46) were positive for salivary pepsin, which was significantly higher than the rate (43.8%, n = 28) of pathological acid reflux as detected by 24-hour esophageal pH monitoring (P = 0.002). @*Conclusions@#Salivary pepsin has an important significance for the diagnosis of GERD and GERD-related disorders. Salivary pepsin and 24-hour esophageal pH monitoring may complement with each other to improve the diagnostic efficiency.

ABSTRACT

To investigate the differences in energy spectrum CT findings between anterior mediastinal lymphoma and thymic carcinoma. Twenty-two cases of anterior mediastinal lymphoma and 28 cases of thymic carcinoma confirmed by biopsy in Tangshan People's Hospital were selected.The CT values and changes of iodine content and water content in lesion sites were measured by energy spectrum analysis software.The differences between anterior mediastinal lymphoma and thymic carcinoma were compared. The single-energy CT value of 40-80 keV in thymus carcinoma was higher than that in anterior mediastinal lymphoma(=0.001,=0.037,=0.042,=0.034,=0.002;=0.016,=0.013,=0.018,=0.024,=0.012).The difference in the single-energy CT value of 90-110 keV between anterior mediastinal lymphoma and thymic carcinoma showed no statistical significance(all >0.05).The concentrations of water in the arterial and venous stages of thymic carcinoma were significantly lower than those in the anterior mediastinal lymphoma(=0.030,=0.037),whereas the iodine concentrations were significantly higher(=0.026,=0.000). Anterior mediastinal lymphoma and thymic carcinoma have remarkably different 40-80 keV single energy CT value and iodine concentration in arterial and venous phases,which may be helpful for the differential diagnosis of these two malignancies.

ABSTRACT

BACKGROUND@#Human immunodeficiency virus (HIV) prevalence among student men who have sex with men (MSM) in college is more than 5.0% and keeps on increasing in China. This study aims to clarify the proportion of HIV recent infection, its propeller and the source among college student MSM.@*METHODS@#We conducted a multicenter cross-sectional study in seven major Chinese cities during 2012-2013. HIV recent infections (≤ 168 days) and incidence was measured and estimated by BED HIV-1 capture enzyme immunoassay (BED-CEIA) testing strategy. HIV-related behaviors and transmitted drug resistance (TDR) were investigated and compared between the college student MSM, <25-year-old non-student youth MSM (NSYM), and ≥25-year-old non-student non-youth MSM (NSNYM), using structured survey, and analyses of drug resistance.@*RESULTS@#Overall, 4,496 (4496/4526, 99.3%) were eligible for enrollment, comprising 565 college student MSM, 1,094 NSYM, and 2,837 NSNYM. The proportion of HIV recent infection were 70.3% (26/37), 50.8% (65/128) and 35.1% (95/271), the HIV incidence rate were 10.0 (95% CI: 6.2-13.9)/100PY, 12.9 (95% CI: 9.8-16.1)/100PY, 6.8 (95% CI: 5.4-8.2)/100PY, and TDR prevalence were 7.4% (2/27), 2.0%, (2/98) and 4.9% (11/226), among student MSM, NSYM, and NSNYM, respectively. Among HIV positive student MSM with age< 21-year-old, the proportion of HIV recent infection is 90.9% (10/11). Factors independently associated with HIV recent infection in student MSM was usage of recreational drug in the past 6 months (AOR: 2.5; 95% CI: 1.0-5.8).@*CONCLUSIONS@#College student MSM had higher proportion of HIV recent infection and TDR than the youth and older MSM in China during 2012-2013. The HIV infections were more likely to happen during the early year of college life among student MSM.

ABSTRACT

Spraying during dental practices can generate quantity of droplets, which transform into droplet nuclei and suspend in the air of clinic in the form of aerosol. Either droplets or aerosols may carry microorganisms and cause air contamination in the hospital, posing potential threat to the health of clinical healthcare staff and patients. The present article summarizes some basic concepts involved in bio-aerosol research and reviews literatures on intervention measures of dental clinic droplet/aerosols to clarify whether there is experimental evidence of aerosol-carrying bacteria in the existing literatures. The aim of this article is to provide evidence for the formulation of guidelines for infection control in dental healthcare practices during the epidemic period of infectious diseases, as well as to provide reference and scientific basis for the management and implementation of infection control measures in daily dental clinical work.

ABSTRACT

Objective:To analyze the clinical characteristics of colorectal neuroendocrine tumor (NET) and to improve the clinical knowledge of this disease.Methods:From January 2011 to December 2018, the clinical data of 61 cases of pathologically diagnosed colorectal NET in Zhangjiagang Hospital Affiliated to Soochow University (19 cases) and The First Affiliated Hospital of Soochow University (42 cases) were collected. The general information, location, clinical manifestations, histological characteristics and pathological grading, immunohistochemical staining, treatment, follow-up and prognosis of the patients were retrospectively analyzed. Chi square test was used for statistical analysis.Results:All the 61 patients with colorectal NET had single lesion, including 36 males (59.0%) and 25 females (41.0%); the age was (56.3±9.2) years. The NET 55 cases (90.2%) located in rectum and six cases (9.8%) in colon. In terms of the main clinical manifestations, 61 cases of colorectal NET had no obvious clinical manifestations or had abdominal discomfort, accounted for 54.1% (33/61) and 16.4% (10/61) respectively. Among 55 patients with rectal NET, 31 patients had no obvious clinical manifestations, and seven patients had abdominal discomfort.Among six patients with colon NET, three patients had abdominal discomfort, and two patients had no obvious clinical manifestations. Among 61 patients with colorectal NET, the maximum tumor diameter was (0.95±1.28) cm, 86.9% (53/61) of them had a maximum tumor diameter ≤2.0 cm, and the pathological grade was mainly G1-NET (93.4%, 57/61). Rectal NET appeared as polypoid or submucosal protrusion, while colon NET showed with ulcer on the surface. Forty-nine cases of colorectal NET received immunohistochemical staining, and the positive rates of synaptophysin, chromogranin A and Ki-67 were 89.8% (44/49), 75.5% (37/49) and 81.6% (40/49), respectively. Fifty-two cases underwent endoscopic treatment, among them 45 cases received endoscopic mucosal resection (EMR) and seven cases received endoscopic submucosal dissection(ESD). Postoperation pathology indicated that specimen resection margin of 17 cases were positive. The positive rate of patients with EMR was 35.6% (16/45), which was higher than that of patients with ESD (one of seven patients with ESD), and the difference was statistically significant ( χ2=3.471, P< 0.05). The follow-up was completed in 54 patients, only one rectal NET patient had local recurrence. Conclusions:Among the patients with colorectal NET enrolled in this study, the proportion of male patients is higher than that of female patients. The lesions are more common in the rectum, and most of them have no obvious clinical symptoms. Polypoid protuberance or ulcer are more often seen under endoscopy. The diagnosis mainly depends on pathological and immunohistochemical results, and the positive rate of ESD margin is lower than that of EMR.

ABSTRACT

Objective:To compare four reconstruction algorithms of 18F-fluorodeoxyglucose (FDG) PET/CT on standardized uptake value (SUV) of pulmonary nodules. Methods:A total of 46 patients (27 males, 19 females; median age: 66 (range: 44-82) years) with solid pulmonary nodules from February 2018 to July 2019 in the First Hospital of Shanxi Medical University who performed 18F-FDG PET/CT imaging were enrolled. All PET/CT images were retrospectively reconstructed by using four algorithms reconstructions including ordered subset expectation maximization (OSEM), OSEM+ time of flight (TOF), OSEM+ TOF+ point spread function (PSF) and block sequential regularized expectation maximization (BSREM) (G1-G4). Nodule and background parameters were analyzed semi-quantitatively and visually. The maximum of SUV(SUV max), mean of SUV(SUV mean) and peak of SUV (SUV peak) were collected by the region of interest (ROI). Nodules were divided into small nodule group (diameter ≤10 mm) and large nodule group (10 mm < diameter ≤30 mm). Kruskal-Wallis rank sum test and Bonferroni method were performed to compare the differences of SUVs between G1-G4, and Spearman correlation analysis was used to analyze the correlation between the change rate of SUV (%ΔSUV) and the diameter of nodules. The receiver operating characteristic (ROC) curve analysis was used to analyze the diagnostic efficacy of SUV for the differential diagnosis of pulmonary nodules and to get the optimal threshold. Results:There were 114 pulmonary nodules (large nodules, n=55; small nodules, n=59). In visual analysis, the visual detection rates of small nodules in G4 were 55.93%(33/59), 44.07%(26/59), 20.34%(12/59) higher than those in G1-G3. Of 114 pulmonary nodules in 46 patients, there were differences in SUV max and SUV mean between G1-G4 (median SUV max : 2.65-5.29, median SUV mean: 2.05-2.99; H values: 20.628 and 17.749, respectively, both P<0.001), G4 had significant increases compared to G1 in SUV max (median 5.29 and 2.65, P<0.001) and SUV mean (median 2.99 and 2.05, P<0.001). The %ΔSUV max (median: 4.45%-52.96%) and %ΔSUV mean (median: 1.69%-47.56%) were negatively correlated with the diameter of nodules (9.75(6.20, 16.58) mm; r s values: -0.371 to -0.354, -0.371 to -0.320, all P<0.001). In 59 small nodules, G1 significantly increased the SUV max of G4 (median 4.05 and 2.14, H=18.327, P<0.001), while G4 significantly increased the SUV mean of G1 and G3 (median 2.31, 1.26 and 1.53, H=16.808, P<0.05). There was no significant difference in SUVs between G1-G4 in 55 large nodules ( H values: 0.812-7.290, all P>0.05). The optimal threshold values of SUV max in G1-G4 were 4.335, 5.185, 5.410, 5.745 and the area of under curves (AUCs) were 0.747, 0.699, 0.756, 0.778 respectively. The AUC of SUV mean and SUV peak also showed a similar trend. Conclusion:Among the four reconstruction algorithms, BRERM can not only enhance the image quality, but also significantly improve the SUV max and SUV mean of lung nodules diameter below 10 mm, and thus its diagnostic threshold of SUV should be appropriately increased.

ABSTRACT

Objective:To investigate nurses' knowledge, attitude and behavior status about the safety management of enteral nutrition tube in a tertiary Class A hospital in Beijing.Methods:A self-designed questionnaire based on reliability and validity was used. Besides, a convenient sampling method was used to select 309 nurses working on enteral nutrition from the hospital.Results:Nurses scored (28.58±6.09)for knowledge, (37.65±5.03)for attitude and (70.01±5.45)for behavior. The percentage of average scores in the three indicators were 57.16%, 94.13% and 93.35%. According to the single factor analysis, the score of behavior differed among nurses with different working years( F=23.61, P=0.032). The score of knowledge differed among nurses with different titles( F=4.48, P=0.012). Besides, the frequency of tube feeding operations had great effects on nurses′ knowledge and behavior ( F=9.64, P<0.001; F=34.59, P=0.018). But there was no statistical difference in the knowledge, attitude, and behavior scores among nurses trained at different frequencies( F=0.85, P=0.497; F=12.56, P=0.231; F=18.97, P=3.479). Conclusions:Nurses have a positive attitude towards the safety management of enteral nutrition tube, but their knowledge level is poor and their behavior needs to be further regulated. It is necessary to carry out relevant training to standardize clinical operations and ensure the safety management of enteral feeding tube.

ABSTRACT

In recent years, researches constituted to show that the occurrence of central nervous system diseases such as Parkinson′s disease, Alzheimer′s disease and multiple sclerosis may have association with the inflammation of central nervous system. The chemokine CX3CL1 is mainly produced by neurons and acts on the central nervous system. After binding to the receptor CX3CR1, by inhibiting the calcium influx induced by NMDA in neurons, it can promote the activation of protein kinase and activate nuclear transcription factor kappa B, reduce the release of inflammatory factors, and stabilize the status of microglia, thus suppress the inflammatory response of the central nervous system and reduce neuronal death, which play a certain role in neuroprotective effect. Therefore, the interaction between CX3CL1 and CX3CR1 is expected to be a new target in the treatment of central nervous system diseases. In this paper, the structure of CX3CL1 and its receptor CX3CR1, the interaction of signal axis and their research progress on central nervous system diseases are reviewed.
