Objective To evaluate the value of diffusion tensor imaging (DTI)in the assessment of uterine fibroids by analyzing uterine fibroids and normal myometrium.Methods Forty-four patients with uterine fibroids confirmed by surgery were included in this study.DTI was performed using double gradient GE HDxt 3.0T and HD Cardiac coil.All data were transferred to GE AW4.5 Workstation software for data processing.Apparent diffusion coefficient(ADC),fractional aniso(FA),volume ratio aniso(VRA)and T2-weighted trace of uterine fibroids and normal myometrium were recorded.Diffusion tensor tractography (DTT)of uterine fibroids and normal myometrium were reconstructed and observed.The ADC,FA,VRA and T2-weighted trace of different regions of interest (ROI)were compared between uterine fibroids and normal myometrium.Results The ADC,FA,VRA and T2-weighted trace of uterine fibroids and normal myometrium were (1.65±0.32)×10 -9 mm2/s and (1.21±0.97)×10 -9 mm2/s,0.20±0.08 and 0.28±0.08,0.05 ± 0.05 and 0.09±0.07,344.22±66.1 9 and 318.97±98.48,respectively.The ADC of normal myometrium was higher than that of uterine fibroids (P =0.009).The FA and VRA of normal myometrium were lower than those of uterine fibroids (P =0.000,P =0.005). There was no statistically significant difference of T2-weighted trace between uterine fibroids and normal myometrium (P =0.1 74). There were obvious differences between uterine fibroids and normal myometrium in direction,arrangement and number of fibers. Conclusion DTI can be used to evaluate the structure difference between uterine fibroids and normal myometrium,which has the potential to improve assessment value of MRI for uterine fibroids.

Objective To evaluate the general level of asthma management in urban areas of China and further promote the national asthma management plan. Methods A multi-center, cross-sectional survey was carried out in 30 provinces of China (except for Tibet) during Oct 2015 to May 2016. It's a questionnaire-based face-to-face survey which included asthma management using peak flow meter (PFM) and pulmonary function test,medication choice of maintenance therapy and asthma education.Results A total of 3 875 asthmatic outpatients were recruited including 2 347(60.6%)females and 1 528(39.4%)males. The mean age was(50.7±16.7)years ranging from 14 to 99.Only 10.1%(388/3 837)patients used PFM as monitoring, whereas 62.1%(2 405/3 874) patients underwent pulmonary function test during the past year. There were 57.4%(2 226/3 875) patients treated with inhaled cortical steroid plus long-acting β2-agonist combinations (ICS+LABA) as daily medication. 43.3%(1 661/3 836) patients were followed up by physicians. Among this population, 1 362 asthmatic outpatients were recruited, who also took part in the asthma control survey in 2007-2008 in 10 cities.In this subgroup,17.9%(244/1 360)were tested by PFM and 66.6%(907/1 362)by pulmonary function test during last year.As to the medication,63.1%(860/1 362) selected ICS+LABA for daily control. There were 50.4%(685/1 359) patients in the follow-up cohort by physicians.Compared to the similar survey conducted in 2007-2008,the proportion of patients with ICS+LABA regimen and follow-up by physicians were markedly higher,while the rate of PFM use did not have significant improvement. Conclusion Although the present level of asthma management in China is still far from ideal, asthma management has improved compared to 8 years ago. Yet the use of PFM does not significantly improve.Asthma action plan and application of PFM should be further promoted to improve the level of asthma management.

Objective:To investigate the characteristics and influencing factors of esophageal stenosis after endoscopic submucosal dissection (ESD) for early esophageal carcinoma.Methods:Patients who underwent ESD in the Digestive Endoscopy Center of the Second Affiliated Hospital of Army Medical University from January 2011 to December 2018 were included. The data were obtained from medical records and follow-up. The influencing factors of stenosis were determined by single factor and Cox regression analysis.Results:A total of 654 patients underwent ESD and 79 (12.1%) of them developed postoperative esophageal stenosis. The median time of stenosis development was 27 (17, 43) days. The morphology and lesion circumferential proportion were independent factors for the occurrence of stenosis after ESD. The stenosis incidence of type Ⅱa was 6.601 times (95% CI: 1.518-28.709, P=0.012) compared with that of type Ⅱc. The incidence of stenosis in lesions with 75%-<100% and 100% circumference was 17.408 times (95% CI: 8.009-37.839, P<0.001)and 52.439 times (95% CI: 23.905-115.029, P<0.001) respectively compared with that of patients <75%. Among the 79 patients, 27 had severe stenosis, and the lesion circumferential proportion was an independent factor for stenosis. Compared with the group of lesion circumferential proportion of less than 75%, the incidences of stenosis of lesion circumferential proportion of 75%-<100% and 100% were 7.775 (95% CI: 1.977-30.577, P=0.003) and 70.062 (95% CI: 19.879-246.926, P<0.001) times respectively. Conclusion:The morphology and lesion circumferential proportion are two independent factors for the occurrence of esophageal stenosis after ESD. Additionally, lesion circumferential proportion is an independent factor for the occurrence of severe esophageal stenosis after ESD.

PURPOSE: Details of patients hospitalized for asthma exacerbation in mainland China are lacking. To improve disease control and reduce economic burden, a large sample survey among this patient population is indispensable. This study aimed to investigate the clinical characteristics and outcomes of such patients.METHODS: A retrospective study was conducted on patients hospitalized for asthma exacerbation in 29 hospitals of 29 regions in mainland China during the period 2013 to 2014. Demographic features, pre-admission conditions, exacerbation details, and outcomes were summarized. Risk factors for exacerbation severity were analyzed.RESULTS: There were 3,240 asthmatic patients included in this study (57.7% females, 42.3% males). Only 28.0% used daily controller medications; 1,287 (39.7%) patients were not currently on inhaled corticosteroids. Acute upper airway infection was the most common trigger of exacerbation (42.3%). Patients with severe to life-threatening exacerbation tended to have a longer disease course, a smoking history, and had comorbidities such as hypertension, chronic obstructive pulmonary disease (COPD), and food allergy. The multivariate analysis showed that smoking history, comorbidities of hypertension, COPD, and food allergy were independent risk factors for more severe exacerbation. The number of patients hospitalized for asthma exacerbation varied with seasons, peaking in March and September. Eight patients died during the study period (mortality 0.25%).CONCLUSIONS: Despite enhanced education on asthma self-management in China during recent years, few patients were using daily controller medications before the onset of their exacerbation, indicating that more educational efforts and considerations are needed. The findings of this study may improve our understanding of hospital admission for asthma exacerbation in mainland China and provide evidence for decision-making.

Objective To evaluate the efficacy of Budesonide/formoterol to control asthma under real-life conditions.Methods A muhi-center, open label, non-interventional study was conducted.Asthma control after 12 week therapy with Budesonide/formoterol was assessed by Asthma Control Questionnaire (ACQ) and modified Asthma Control Questionnaire (ACQ5).Results A total of 360 asthma patients were recruited,including 228 adult patients and 132 child patients.After 12 weeks' therapy,all the patients' medium value of ACQ was decreased significantly from 2.03 (adults 2.20, children 1.74) at baseline to 0.60 (adults 0.78, children 0.29) (P < 0.0001), and the medium value of ACQ5 was also decreased significantly from 2.4 (adults 2.24, children 1.76) at baseline to 0.47 (adults 0.62, children 0.20) (P < 0.0001).Conclusion Budesonide/formoterol is effective in asthma treatment, by which most asthma patients obtain and maintain clineal control.

Objective To characterise the alterations of serum autoantibodies for cyclinB1,p62,Koc-IMP1 and survivin in the subjects with esophgeal and gastric cardia carcinoma and precancerous lesion and their expres-sions in the esophageal and gastric cardia cancer tissue.Methods Enzyme-linked immunoassay and tumor-associated antigen mini-array (consisting of five full-length recombinant proteins,including eyefinB1-p62-Koc,IMP1 and Survivin)were applied to determine the serum level of the autoantibodies of these antigens on 376 subjects with e-sephageal and gastric cardia carcinoma and precancerous lesions.At the same time,the expression of these antigens was detected by immunohistochemical method(ABC)on 13 patients with esophageal cancer and 16 with gastric car-dia cancer.Results All of the 5 antigens determined,the linear correlation Was observed for the detection frequency of cyclinB1,IMPI and p62 in esophageal carcinogenesis,and for p62 in gastric cardia multi-stage progression from normal to precancerous and cancerous lesions(P<0.05).The detection rale with single positive antoantibody im-munoreactivity for both esophageal and gastric cardia cancers were low.However.the positive detection mte for both esophageal and gastric cardia cancer increased apparently when the multiple positive markers were combined together for analysis,which increased tO 3～5 and 3～4 folds respectively.Furthermore,the difference in autoantibody immu-noreactive rate was significant with the lesion progressed from mild tO severe precancerous lesions and to cancer both in esophageal and gastric cardia cancers(P<0.05).The positive immunoreactions of the 5 antigens were detected in cancer tissues.The positive immunostaining rates for cyclinB1,Koc,IMP1 and Survivin both in esophageal and gastric cardia cancers were higher compared to their serllin positive rate of autoantibodies I P<0.05).Of the pa-tients with positive immunostaining in the two cancer tissues,the autoantibodies in the serum for the corresponding antigens could be detected in the same patient.Conclusion The production of the tumor-associated autoantibodies is related tO antigens.The screening rate through serum tumor-associated antigen mini-array for the patients with e-sophageal and gastric cardia carcinoma and precancerous lesions has been increased apparently with combined analy-sis of multiple autoantibodies than with single one.

Objective To analyze the clinicopathological features and lymph node metastases characteristics of intrahepatic cholangiocarcinoma (ICC).Methods The retrospective case-control study was conducted.The clinicopathological data of 1 321 ICC patients who were admitted to 12 hospitals from April 2007 to November 2017 were collected,including 182 in the Eastern Hepatobiliary Surgery Hospital of the Second Military Medical University,173 in the First Affiliated Hospital of Xi'an Jiaotong University,156 in the First Hospital Affiliated to Army Medical University (Third Military Medical University),139 in the Cancer Center of Sun Yatsen University,128 in the Zhongshan Hospital of Fudan University,113 in the Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine,109 in the First Affiliated Hospital of Dalian Medical University,84 in the Tianjin Medical University Cancer Institute and Hospital,65 in the First Affiliated Hospital of Zhengzhou University,62 in the Affiliated Hospital of North Sichuan Medical College,58 in the Affiliated Drum Tower Hospital of Nanjing University Medical School and 52 in the Second Affiliated Hospital of Zhejiang University School of Medicine.Treatment planning was respectively determined by comprehensive hospitals according to clinical features and results of related examinations.Surgical procedures were performed based on the results of intraoperative examinations and patients' conditions.Observation indicators:(1) laboratory examination and treatment situations;(2) relationship between clinicopathological features and primary tumor location and diameter;(3) diagnosis of lymph node dissection and metastases;(4) relationship between clinicopathological features and lymph node metastases.Measurement data with normal distribution were represented as x±s,and comparison between groups was done by the t test.Measurement data with skewed distribution were described as M (range).Comparison of count data were analyzed using the chi-square test.Results (1) Laboratory examination and treatment situations:of 1 321 patients,cases and percentages of positive hepatitis B virus (HBV),positive serum alpha-fetoprotein (AFP) (＞ 20 μg/L),positive serum carcinoembryonic antigen (CEA) (＞ 5 μg/L),positive serum alanine transaminase (ALT) (＞75 U/L),positive serum CA19-9 (＞37 U/mL) and positive serum total bilirubin (TBil) (＞20 μmol/L) were respectively 202,80,329,207,590,300 and 15.586％ (202/1 296),7.339％(80/1 090),26.299％ (329/1 251),16.587％ (207/1 248),49.789％(590/1 185),24.000％ (300/1 250).Of 1 321 patients,1 206 underwent surgery,including 904 with hepatectomy,193 with transcatheter arterial chemoembolization (TACE),72 with percutaneous transhepatic biliary drainage (PTBD),3 with endoscopic retrograde cholangiopancreatography (ERCP),3 with PTBD + ERCP and 31 with other treatments;115 had missing registration of surgical procedures.(2) Relationship between clinicopathological features and primary tumor location and diameter:① Relationship between clinicopathological features and primary tumor location:cases with CA19-9 level ≤ 37 U/mL,38-200 U/mL and ＞ 200 U/mL were respectively 227,91,146 with primary tumor located in left liver and 282,134,137 with primary tumor located in right liver.Cases combined with hepatitis and intrahepatic bile duct stone were respectively 67,73 with primary tumor in left liver and 111,47 with primary tumor in right liver,with statistically significant differences in above indictors (x2 =6.710,5.656,12.534,P＜0.05).The results of further analysis showed that incidence age of ICC was (63± 10)years old in patients with hepatitis and (59± 10) years old in patients without hepatitis,with statistically significant differences (t =4.840,P＜0.05).② Relationship between clinicopathological features and primary tumor diameter:cases with primary tumor diameter ≤ 3 cm,with 3 cm ＜ primary tumor diameter ≤ 5 cm and with primary tumor diameter ＞ 5 cm were respectively 159,250,229 with CEA level ≤ 5 pg/L and 40,65,95 with CEA level ＞ 5 μg/L and 165,258,286 with ALT level ≤ 75 U/L and 34,57,36 with ALT level ＞ 75 U/L and 148,242,281 with TBil level ≤ 20 μmol/L and 51,73,43 with TBil level ＞ 20 μmol/L,and 37,70 and 131 patients had satellite loci of tumor,with statistically significant differences in above indictors (x2=8.669,6.637,15.129,34.746,P＜0.05).(3) Diagnosis of lymph node dissection and metastases:of 904 patients with hepatectomy,346 received lymph node dissection,total number,number in each patient and median number of lymph node dissected were respectively 1 894.0,5.5 and 4.0 (range,1.0-26.0);157 had lymph node metastases,with a rate of lymph node metastasis of 45.376％ (157/346),number and number in each patient of positive lymph node were respectively 393.0 and 2.5.Of 346 patients with lymph node dissection,114 had lymph node metastasis by preoperative imaging examination,postoperative pathological examinations confirmed 64 with lymph node metastasis and 50 without lymph node metastasis;232 didn't have lymph node metastasis by preoperative imaging examination,postoperative pathological examinations confirmed 93 with lymph node metastasis and 139 without lymph node metastasis.The sensitivity,specificity and diagnostic accuracy by imaging examination were respectively 40.8％,73.5％ and 58.7％.(4) Relationship between clinicopathological characteristics and lymph node metastases:lymph node metastasis rate was respectively 51.397％ (92/179) in patients with primary tumor located in left liver,39.103％ (61/156) in patients with primary tumor located in right liver,34.615％(18/52) in patients with primary tumor diameter ≤ 3 cm,42.500％(51/120) in patients with 3 cm ＜ primary tumor diameter ≤ 5 cm,52.980％(80/151) in patients with primary tumor diameter ＞ 5 cm,48.790％(121/248) in patients with CEA ≤ 5 μg/L,59.302％ (51/86) in patients with CEA ＞ 5 μg/L,40.234％ (103/256) in patients with TBil ≤ 20 μmol/L,35.106％ (33/94) in patients with TBil ＞ 20 μmol/L,with statistically significant differences in above indictors (x2 =5.078,6.262,9.456,5.156,P ＜ 0.05).Conclusions The related etiological factors may be different due to different primary location of ICC.Primary tumor in left liver is significantly associated with intrahepatic bile duct stone of left liver,and primary tumor in right liver is associated with combined hepatitis,while combined hepatitis could lead early occurrence of ICC.At present,there is a low rate of lymph node dissection in ICC patients and a high lymph node metastasis rate in patients receiving lymph node dissection.Lymph node metastasis is associated with primary tumor location and diameter,levels of CEA and TBil.Lymph node metastasis rate in left liver is higher than that in right liver,and is getting higher with increased primary tumor diameter.

Objective:To explore the difference of high-risk factors between early-onset and late-onset pre-eclampsia, and to further understand high-risk factors of pre-eclampsia.Methods:Clinical data of pre-eclampsia pregnant women in 160 medical institutions in China in 2018 were retrospectively analyzed, including 8 031 cases of early-onset pre-eclampsia and 12 969 cases of late-onset pre-eclampsia. The proportion of high-risk factors, different body mass index (BMI) and age stratification between early-onset group and late-onset group were compared.Results:(1) Univariate analysis of high-risk factors: the proportions of high-risk factors in early-onset group and late-onset group were compared, and the differences were statistically significant (all P<0.05). Among them, the proportions of primipara and multiple pregnancy in early-onset group were lower than those in late-onset group, while the proportions of pregnant women with advanced age, irregular antenatal examination, obesity, family history of hypertension, pre-eclampsia, diabetes, kidney diseases, immune system diseases and assisted reproductive technology were higher than those in late-onset group. (2) Hierarchical analysis of BMI: the proportion of pregnant women with BMI≥24 kg/m 2 in early-onset group [48.2% (2 828/5 872) vs 45.5% (4 177/9 181), respectively; P=0.001] and the proportion of pregnant women with BMI ≥28 kg/m 2 in early-onset group [19.5% (1 143/5 872) vs 18.0% (1 656/9 181), respectively; P=0.028] were significantly higher than those in late-onset group. (3) Age stratification analysis: the proportion of pregnant women aged 35-39 years in the early-onset group [21.8% (1 748/8 023) vs 17.5% (2 110/12 068), respectively; P<0.01], the proportion of pregnant women 40-44 years old [6.8% (544/8 023) vs 5.4% (648/12 068), respectively; P<0.01], and the proportion of pregnant women ≥45 years old [0.7% (58/8 023) vs 0.5% (57/12 068), respectively; P=0.021] were significantly higher than those in the late-onset group. (4) Multivariate analysis: advanced age (≥35 years old), multiple pregnancy, irregular antenatal examination or transfer from other hospitals, family history of hypertension (including paternal, maternal and parental lines), previous history of pre-eclampsia, kidney diseases, immune system diseases (systemic lupus erythematosus, antiphospholipid antibody syndrome) and assisted reproductive technology pregnancy were the risk factors affecting the severity of pre-eclampsia (all P<0.05). Conclusion:Pregnant women with high risk factors such as age ≥35 years old, BMI ≥24 kg/m 2 before pregnancy, family history of hypertension, history of pre-eclampsia, chronic kidney diseases, immune diseases (mainly including systemic lupus erythematosus and antiphospholipid syndrome) and assisted reproductive technology are more likely to have early-onset pre-eclampsia.

BACKGROUNDPhosphatase and tensin homologue on chromosome ten (PTEN) acts as a convergent nodal signalling point for cardiomyocyte hypertrophy, growth and survival. However, the role of PTEN in cardiac conditions such as right ventricular hypertrophy caused by chronic hypoxic pulmonary, hypertension remains unclear. This study preliminarily discussed the role of PTEN in the cardiac response to increased pulmonary vascular resistance using the hypoxia-induced PH rats.

METHODSMale Sprague Dawley rats were exposed to 10% oxygen for 1, 3, 7, 14 or 21 days to induce hypertension and right ventricular hypertrophy. Right ventricular systolic pressure was measured via catheterization. Hypertrophy index was calculated as the ratio of right ventricular mass to left ventricle plus septum mass. Tissue morphology and fibrosis were measured using hematoxylin, eosin and picrosirius red staining. The expression and phosphorylation levels of PTEN in ventricles were determined by real time PCR and Western blotting.

RESULTSHypoxic exposure of rats resulted in pathological hypertrophy, interstitial fibrosis and remodelling of the right ventricle. The phosphorylation of PTEN increased significantly in the hypertrophic right ventricle compared to the normoxic control group. There were no changes in protein expression in either ventricle.

CONCLUSIONHypoxia induced pulmonary hypertension developed pathological right ventricular hypertrophy and remodelling probably related to an increased phosphorylation of PTEN.
