ABSTRACT
OBJECTIVE: To investigate the variation of etiology and complication of liver cirrhosis(LC) by the comparative analysis of etiology,complications, sex and age in LC patients in 2012 and in 2017. METHODS: In this cross-sectional study, we collected cases of LC admitted in 2012 and 2017 and reviewed the medical records. The demographics, etiology and complications were collected and we compared the composition ratios of etiology and complications as well as the sex composition and age differences between different etiology in the 5-year period. RESULTS: 3065 patients(including 1451 in 2012 and 1614 in 2017) were identified in this study. There was no significant difference in etiology of LC caused by HBV infection(that was 56.31% in 2012 and 53.41% in 2017, respectively.(χ2=2.591, P=0.107). The composition ratio of alcohol and autoimmune diseases increased. That of alcohol diseases was 12.96% in 2012 and 16.36% in 2017(χ2=7.027, P=0.008).That of autoimmune diseases was 9.92% in 2012 and 13.07% in 2017(χ2=7.398, P=0.007). The composition ratio of HCV infection decreased from 14.82% to 11.28% having statistically significant difference(χ2=8.497, P=0.004). The three former complications in 2012 were UGH(15.64%), HCC(15.30%,), SBP(12.68%,), which were HCC(21.07%), UGH(13.38%), SBP(11.03%) in 2017. HCC was more common(that was 15.30% in 2012 and 21.07% in 2017) having significant difference(χ2=16.964, P<0.001).LC caused by HBV and alcohol were mainly males, which slightly decreased having no significant difference. LC caused by autoimmune diseases was mainly female, which slightly increased having no significant difference. The LC patients infected by HBV and HCV were older than before when were hospitalized.That of HBV was(50.08±11.11) years old in 2012 and(52.39±11.56) years old in 2017(t=-4.163, P=0.004). That of HCV was(57.22±10.52)years old in 2012 and(61.13±10.25) years old in 2017(t=-3.732, P <0.001). CONCLUSION: Compared with 5 years ago, HBV infection remained the major cause of liver cirrhosis, whereas alcohol and autoimmune diseases increased and HCV infection decreased. HCC was the most common of LC complications. LC patients caused by different etiology had different prevalence in sex and were hospitalized in different ages. Patients infected by HBV/HCV seemed to be older than before when they were hospitalized.
ABSTRACT
Abstract Objective: Total bilirubin is beneficial for protecting cardiovascular diseases in adults. The authors aimed to investigate the association of total bilirubin, red blood cell, and hemoglobin levels with the prevalence of high blood pressure in children and adolescents. Methods: A total of 3776 students (aged from 6 to 16 years old) were examined using cluster sampling. Pre-high blood pressure and high blood pressure were respectively defined as the point of 90th and 95th percentiles based on the Fourth Report on the Diagnosis, Evaluation, and Treatment of High Blood Pressure in Children and Adolescents. Both systolic and diastolic blood pressure were standardized into z-scores. Results: Peripheral total bilirubin, red blood cell and hemoglobin levels were significantly correlated with age, and also varied with gender. Peripheral total bilirubin was negatively correlated with systolic blood pressure in 6- and 9-year-old boys, whilst positively correlated with diastolic blood pressure in the 12-year-old boys and 13- to 15-year-old girls (p < 0.05). Higher levels of red blood cell and hemoglobin were observed in pre-high blood pressure and high blood pressure students when compared with their normotensive peers (p < 0.01). The increases in red blood cell and hemoglobin were significantly associated with high blood pressure after adjusting for confounding factors. The ORs (95% CI) of each of the increases were 2.44 (1.52-3.92) and 1.04 (1.03-1.06), respectively. No statistical association between total bilirubin and high blood pressure was observed (p > 0.05). Conclusion: Total bilirubin could be weakly correlated with both systolic and diastolic blood pressure, as correlations varied with age and gender in children and adolescents; in turn, the increased levels of red blood cell and hemoglobin are proposed to be positively associated with the prevalence of high blood pressure.
Resumo Objetivo: A bilirrubina total é benéfica para proteger contra doenças cardiovasculares em adultos. Nosso objetivo foi investigar a associação dos níveis de bilirrubina total, glóbulos vermelhos e hemoglobina com a prevalência de pressão arterial elevada em crianças e adolescentes. Métodos: Um total de 3.776 estudantes (com idade entre 6-16 anos) foram examinados utilizando uma amostra em blocos. A pressão arterial elevada anterior e a pressão arterial elevada foram definidas como o 90° e 95° percentil, respectivamente, com base nos critérios do Quarto Relatório sobre Diagnóstico, Avaliação e Tratamento da Pressão Arterial elevada em Crianças e Adolescentes. A pressão arterial sistólica e pressão arterial diastólica foram padronizadas no escore z. Resultados: Os níveis periféricos de bilirrubina total, glóbulos vermelhos e hemoglobina foram significativamente correlacionados à idade, que também variou de acordo com o sexo. A bilirrubina total periférica apresentou uma correlação negativa com a pressão arterial sistólica em meninos com 6 e 9 anos, ao passo que apresentou uma correlação positiva com a pressão arterial diastólica em meninos de 12 anos e meninas de 13 a 15 anos (p < 0,05). Foram observados níveis mais elevados de glóbulos vermelhos e hemoglobina em estudantes com pressão arterial elevada anterior e pressão arterial elevada em comparação a indivíduos normotensos (p < 0,01). Os aumentos de glóbulos vermelhos e hemoglobina tiveram uma associação significativa com a pressão arterial elevada após ajuste dos fatores de confusão. As RC (IC de 95%) de cada um dos aumentos foram 2,44 (1,52-3,92) e 1,04 (1,03-1,06) respectivamente. Não foi observada nenhuma associação estatística entre o nível de bilirrubina total e a pressão arterial elevada (p > 0,05). Conclusão: A bilirrubina total pode ter correlações fracas com a pressão arterial sistólica e a pressão arterial diastólica, variando de acordo com a idade e o sexo em crianças e adolescentes, enquanto isso, propõe-se que o aumento dos níveis de glóbulos vermelhos e hemoglobina está positivamente associado à prevalência de pressão arterial elevada.

Objective To evaluate the value of combined special staining technique in observing pathological changes in blood vessels. Methods Totally 999 vascular specimen were harvested from patients with complete medical records,clear diagnosis,and age≥18 years in the Pathology Department of Beijing Anzhen Hospital from January 2014 to September 2017.All specimen were stained with HE,Verhoef-Van Gieson,AB/PAS,and Masson. Then,the result of HE staining was compared with that of the combined special staining (Verhoef-Van Gieson,AB/PAS,and Masson).Results HE staining only showed a small amount of elastic fiber fracture. In contrast,the combined special staining clearly showed the pathological changes including fractures,decreased elastic fibers,and aggregation of extracellular mucous matrix. Diseases in these 999 patients included aneurysm of sinus of valsalva (SVA) (n=3),aortic root aneurysm (ARA) (n=177),thoracic aortic aneurysm (TAA) (n=78),abdominal aortic aneurysm (AAA) (n=17),total thoracoabdominal aortic aneurysm (tTAAA) (n=32),and aortic dissection (AD) (n=692). The median scores of combined special staining of SVA (Z=3.857,P=0.040),ARA (Z=14.307,P=0.000),TAA (Z=26.939,P=0.000),AAA (Z=22.412,P=0.000),tTAAA (Z=15.926,P=0.000),and AD (Z=39.213,P=0.000) were significantly higher than that of HE staining. Conclusion The combined Verhoeff-Van Gieson,AB/PAS,and Masson special staining is an effective technique for observing pathological changes of elastic fibers and mucus in blood vessels.
ABSTRACT
Objective To investigate the knowledge and practice of residents about schistosomiasis prevention and control in endemic areas of Jingzhou City,Hubei Province after the disease transmission being controlled,so as to provide the valuable in-formation for formulating an efficient health education and intervention strategy.Methods The residents were selected by using the cluster sampling method and investigated with questionnaires in Jiangling County and Gong'an County,Jingzhou City,Hu-bei Province,and the data were analyzed by using the descriptive analysis method,Chi-square tests and logistic regression.Re-sults In a total,826 available questionnaires were obtained with 100% of valid rate.Among them,97.0% of the interviewee knew schistosomiasis,and 86.3% knew that the infection happened by contacting water containing cercariae.The residents in el-der age(41-84 years)had higher awareness rates than the residents in lower age(6-17 years),about the regions of epidemic area(χ 2=57.860),infection route of schistosomiasis(χ 2=87.045),advanced schistosomiasis symptoms(χ 2=27.268)and On-comelania hupensis being as intermediate host(χ 2=55.856)(all P<0.05).The males had higher awareness rates of epidemic areas than the females(χ2=13.442,P<0.05).For personal behavior,36.6% of the interviewee had experience of contacting lake or pond water many times a day,and 66.5% had the willingness to participate in schistosomiasis health education.Conclu-sion In the investigation areas,Jiangling County and Gong'an County,the awareness rates of the residents about schistosomia-sis prevention and control are higher,and we should strengthen the health education and behavior intervention,especially in the students of middle and primary schools to help them have the self-protection ability efficiently.
ABSTRACT
Objective To investigate the effects of ω-3 polyunsaturated fatty acid(PUFA)on oxidative stress produc-tion and apoptosis in hippocampus of neonatal rats with brain injury induced by lipopolysaccharide(LPS). Methods Forty-eight neonatal Sprague Dawley rats(3 days)were randomly divided into control group,LPS group,ω-3 PUFA group and ω-6 PUFA group,with 12 rats in each group. The rats in the LPS group,ω-3 PUFA group and ω-6 PUFA group were given 0. 6 mg·kg - 1 LPS via intraperitoneal injection,then equal volume of saline,ω-3 PUFA and ω-6 PUFA was immediately given via intraperitoneal injection respectively;while the rats in the control group were all given equal volume of saline. The rats in each group were sacrificed at 24 hours after intraperitoneal injection with saline or fat emulsions to obtain the hippocampus. The levels of superoxide dismutase(SOD)and malondialdehyde(MDA),reduced glutathion(GSH),oxidized glutathione(GSSG) were detected and GSSG/ GSH was calculated. The apoptotic index was measured by terminal deoxynucleotidyl transferase-me-diated dUTP nick end labeling. Results Compared with the control group,the levels of SOD and GSH in hippocampus of rats in the LPS group,ω-6 PUFA group and ω-3 PUFA group were significantly decreased(P < 0. 05),and the levels of MDA, GSSG and the ratio of GSSG/ GSH were significantly increased(P < 0. 05). Compared with the LPS group,the levels of SOD and GSH in hippocampus of rats in ω-6 PUFA group were significantly decreased(P < 0. 05),the levels of MDA,GSSG and the ratio of GSSG/ GSH were significantly increased(P < 0. 05);the levels of SOD and GSH in hippocampus of rats in ω-3 PU-FA group were significantly increased(P < 0. 05),the levels of MDA,GSSG and the ratio of GSSG/ GSH were significantly de-creased(P < 0. 05). Compared with the ω-6 PUFA group,the levels of SOD and GSH in hippocampus of rats in ω-3 PUFA group were significantly decreased(P < 0. 05),the levels of MDA,GSSG and the ratio of GSSG/ GSH were significantly in-creased(P < 0. 05). The apoptotic index in the LPS group,ω-6 PUFA group and ω-3 PUFA group was higher than that in the control group(P < 0. 05). The apoptotic index in the ω-6 PUFA group was higher than that in the LPS group(P < 0. 05). The apoptotic index in the ω-3 PUFA group was lower than that in the LPS group and ω-6 PUFA group(P < 0. 05). Conclusion ω-3 PUFA can alleviate the oxidative stress,and decrease the apoptosis of hippocampus in neonatal rats with brain injury in-duced by LPS. So it has a neuroprotective effect in brain injury induced by LPS.
ABSTRACT
AIM:To investigate the dry eye prevalence, tear film function and corneal status in patients with thyroid associated ophthalmopathy ( TAO) .?METHODS: Totally 218 patients ( 436 eyes ) with TAO admitted to our hospital from September 2014 to August 2016 were selected and divided into two groups according to TAO's clinical activity score ( CAS): score≥ 4 divided into active patients, 72 cases of 144 eyes;score<4 points were inactive patients, a total of 146 cases of 292 eyes;according to the patient's course of the situation was divided into three groups, less than 1a for the short course of disease, a total of 133 cases of 266 eyes;course of disease in the 1-2a in the medium course group, there were 40 eyes of 80 eyes and 45 eyes of 90 eyes in more than 2a, as long course group. Contrast patients were examined by corneal fluorescein staining ( FL) , tear film break-up time ( BUT ) and tear secretion test ( SⅠt ) Happening.?RESULTS: In 218 patients, 138 cases of 276 eyes were diagnosed as dry eye. The prevalence rate of active period patients was higher than that of inactive patients, and the difference was statistically significant (P<0. 05). The prevalence rate in the short course group was higher than that of the middle course group and the long course group, and the difference was statistically significant compared with that in long course group (P<0. 05). There was no significant difference between any two of the three groups in BUT and SⅠt detection (P>0. 05), and the differences was statistically significant in the detection of FL (P<0. 05). The differences of FL, BUT and SⅠt between the inactive patients and the active patients were statistically significant (P<0. 05).? CONCLUSION: Most patients with TAO have inadequate tear secretion and tear film instability. The corneal epithelium of 1/3 TAO patients is damaged and the incidence of dry eye disease is significantly higher than that of normal subjects.
ABSTRACT
OBJECTIVES@#To estimate lung volume in normal population by a combination of multi-slice spiral CT and Pulmo software.@*METHODS@#Scans of the lung were performed on 45 normal individuals using Emotion 16-slice spiral CT and Pulmo software. A measurement instrument of work station was used to measure the vertical diameter of left and right lungs, the maximum anteroposterior and transverse diameters at the layers of apex pulmonis 1 cm below, arcus aortae, subcarinal and diaphragmatic dome, and the lung volume. Regression analysis was performed on normal lung volume and each measured parameter by SPSS 20.0 and an optimal model was selected.@*RESULTS@#The goodness of fit between the best curvilinear equations of the normal bilateral lung volumes was 0.981. The goodness of fit between the curvilinear equations of the normal bilateral lung volume and the product of the vertical diameter and the maximum transverse diameter of diaphragmatic dome were 0.977 and 0.972, respectively. Fifteen cases were selected to make a retrospective test on the 3 models. No significant difference was found between the estimated and measured with Pulmo software lung volumes.@*CONCLUSIONS@#The normal lung volume before injury can be estimated by the curvilinear equations established in this study. The percentage of lung compression can be measured based on the volume of compressed lung, which can provide a reference for the identification of lung compression degree.

<p><b>BACKGROUND</b>Overexpression of breast cancer-specific gene 1 (SNCG) is associated with poor prognosis in advanced breast cancer patients. This study aimed to determine the effects of SNCG knockdown in breast cancer cells by using small hairpin RNA (shRNA).</p><p><b>METHODS</b>Four different SNCG shRNA oligonucleotides were designed and chemically synthesized to construct mammalian expression vectors. These vectors were then stably transfected into a breast cancer MCF-7 cell line to knockdown SNCG expression. After SNCG knockdown was confirmed, the stable cell lines were inoculated into nude mice. SNCG mRNA and protein expressions were analyzed by semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR) and immunohistochemistry, respectively in both the stable cell lines and xenografts.</p><p><b>RESULTS</b>All four SNCG shRNA constructs significantly reduced SNCG mRNA and protein levels in MCF-7 cells, as compared to the unrelated sequence control shRNA and the liposome control mice (P < 0.05). SNCG-knockdown MCF-7 cells formed significantly smaller tumor masses than cells expressing the unrelated sequence control or the liposome control mice (P < 0.05).</p><p><b>CONCLUSION</b>SNCG shRNA effectively suppressed breast cancer cell formation in vivo and may be a useful clinical strategy to control breast cancer.</p>

<p><b>OBJECTIVE</b>To analyze the clinical features, diagnosis, treatment, and prognosis of epithelioid sarcoma (ES).</p><p><b>METHODS</b>The clinical data of 13 cases with epithelioid sarcoma in the Tianjin Medical University Cancer Institute and Hospital from March 1995 to December 2009 were collected and analyzed. There were 10 males and 3 females in the group, with an average age of 41.5 years (range: 13 to 68 years). Nine patients had classic ES and 4 had proximal-type ES. Surgery was the mainstay of treatment. After the operation, four patients received radiotherapy, five received chemotherapy, and one received chemoradiotherapy.</p><p><b>RESULTS</b>Of the 13 cases, only 1 had multi-locus lesion. The average tumor size was (6.07 ± 1.34) cm. The lymph node involvement was found in 46.2% of the patients. Local and distant failure occurred in 50% and 30% patients, respectively. The most common site for dissemination was the lung. Four cases died within 3 years after initial operation. The 1-, 2-, 5-, 10-year overall survival rates of the 11 cases were 72.7%, 54.5%, 27.3% and 9.1%, respectively, with a median survival time of 27 months.</p><p><b>CONCLUSIONS</b>Epithelioid sarcoma is a rare disease. The prognosis for patients with epithelioid sarcoma is poor because of a high propensity for local recurrence, lymph node metastases, and/or distant metastases. The definite diagnosis depends mainly on the pathologic examination. Wide surgical excision is the mainstay treatment, and radiation and chemotherapy have been used occasionally as adjuvant therapy but have had limited success.</p>
