Acute mesenteric ischemia (AMI) is a lifethreatening disease,with high mortality rate and is easily misdiagnosed.Rapid and acute detection of the AMI and its primary diseases by multi-slice computed tomography (MSCT) and computed tomography angiography (CTA) is of great significance.The clinical data of 31 patients with AMI who were admitted to the Xidian Group Hospital from January 2005 to June 2013 were retrospectively analyzed.Stenosis or occlusion of the mesenteric blood vessels,diminished or absent enhancement of the bowel wall are the direct signs of CT,thickening of the bowel wall is the most typical indirect sign of CT.Dilatation or collapse of the bowel lumen and swelling of the mesenterium are the common CT signs.Pneumatosis intestinalis and gas in the portomesenteric vein are reliable CT signs of the Intestinal Infarction.Artery and venous embolism,atherosclerosis,vasculitis,aortitis,strangulated intestinal obstruction and superior mesenteric artery dissection are the possible causes of AMI.

Objective:To study the expressione of autophagy-related protein Beclin-1 and LC3 in cortex and hippocampus of rats after cerebral ischemia reperfusion injury and the efficacy of Edaravone.Methods:Sprague Dawley rats were randomly divided into sham group,model group and Edaravone group.The cerebral ischemia reperfusion model was induced via Zea Longa with blocking the middle cerebral artery of 2 h and reperfusing of 24 h.Animals assigned to sham group were only separated left common carotid artery.Edaravone was injected intraperitoneally at a dose of 1 0 mg/kg at 15 min before reperfusion.The condition of nerve injury of rats was conducted by Neurobehavioral score.The degree of brain injury and success of model were determined based on 2,3,5-triphenyltetrazolium chloride(TTC)staining.The changes of neuron stained by hematoxylin and eosin (HE) in cortex and hippocampus were observed.The expression of Beclin-1 and LC3 was measured by immunohistochemistry.Results:After cerebral ischemia reperfusion the neurobehavioral score of edaravone group was(2.00± 0.67),which was obcviously less than(2.50± 0.53) of model group(P＜0.05).The infraction focus and the neuron injury in cortex and hippocampus neurons were also observed in model group,and the edaravone group reduced above expression.The positive rate of Beclin-1 of each group in cortex were (1 1.08± 0.85)％,(33.42± 1.57)％ and (25.61± 1.39)％,there was significant difference between model group with sham group and edaravone group (P＜0.05).The positive rate of Beclin-1 of each group in hippocampus were (10.34± 0.21)％,(31.82± 1.73)％ and (22.74± 1.26)％,there was significant difference between model group with sham group and edaravone group(P ＜ 0.05).The positive rate of LC3 of each group in cortex were (15.33± 0.47)％,(39.72± 1.73)％ and (28.53± 1.61)％,there was significant difference between model group with sham group and edaravone group(P＜0.05).The positive rate of LC3 of each group in hippocampus were (13.74± 0.37)％,(32.53± 1.43)％ and(25.38± 1.23)％,there was significant difference between model group with sham group and edaravone group (P＜0.05).Conclusion:The expression of Beclin-1 and LC3 was increased after cerebral ischemia reperfusion.Edaravone may reduce autophagy and brain injury through downregulation the expression of Beclin-1 and LC3.

BACKGROUND:The greatest risk of osteoporosis in total knee arthroplastyisperioperative and long-term periprosthetic fractures. However, limited by the traditional concept of osteoarthritis patientswhousualy not associated with osteoporosis, domestic clinical trials have not given enough attention to the osteoporosis before total knee arthroplasty.
OBJECTIVE:To analyze the osteoporosis and its relative factors in osteoarthritis patients before total knee arthroplasty.
METHODS:Data of 81 cases (81 knees) of knee osteoarthritiswhounderwenttotal knee arthroplasty in the Department of Joint Surgery of Tianjin People’s Hospital from January 2012 to November 2014 were retrospectively analyzed. They received lumbar spine and hip bone mineral density examination before surgery. The correlation of bone mineral density with age, body mass index, knee motion range,and knee deformity was analyzed before surgery. The independent risk factors for osteoporosis before replacement were analyzed.
RESULTS AND CONCLUSION:(1) Of 81 patients, there were normal bone mineral density in 25 cases (31%), osteopenia in 35 cases (43%),andosteoporosis in 21 cases (26%). Al 10 males had no osteoporosis and 21 in 71 female cases suffered osteoporosis (30%). Theincidence of osteoporosis in females was significantly higher than in male patients (P=0.046). (2) There was a linear correlation of bone mineral density with age and body mass index (correlation coefficientr=-0.230, 0.225). (3) The age of≥65 years and body mass index≥25 kg/m2were independent risk factors of osteoporosis before replacement (P< 0.05). (4) Patients with knee osteoarthritis had higher incidence of osteopenia and osteoporosis before total knee arthroplasty. The degree of osteoporosis was negatively correlated with age, but positively correlated with body mass index. The age of≥65 years and body mass index < 25 kg/m2were independent risk factors for preoperative osteoporosis. Thus, bone mineral density examination is essential for those patients before total knee arthroplasty.

The expansion movement of the market and the reverse movement that it has encountered to control its expansion constituted the " double movement" written by the British scholar Karl Polan.In traditional China,because the market was strictly embedded in the social,political,economic and ethical structure,there was no so-called " double movement",and the trust between doctors and patients was naturally established and historical-ly continued.Since the reform and opening up,with the gradual introduction of market mechanism in the reform of medical system,the market was increasingly " un-embedded" and expanded rapidly.At the same time,the socie-ty represented by the patients and their families gradually began to wake up and took action against market expan-sion,forming a more typical trend of " double movement" and triggering a more obvious crisis of doctor-patient trust.From the perspective of "double movement",to rebuild doctor-patient trust in the new period must re-em-bed the market into the society and strictly regulate some spontaneous social reverse movements.

Objective To investigate the changes of serum Copeptin and matrix metalloproteinase-9 (MMP-9) in children with chronic heart failure (CHF) and its clinical significance. Methods A total of 186 children with CHF were selected for CHF group, including 78 cases of cardiac function grade Ⅱ, 65 cases of grade Ⅲ, and 43 cases of grade Ⅳ. There were 57 cases of dilated cardiomyopathy, 68 cases of congenital heart disease and 61 cases of other diseases. Another 85 healthy children from health checkup were chosen as controls. The levels of serum Copeptin and MMP-9 were determined by enzyme linked immunosorbent assay (ELISA), and the level of N-terminal pro-brain natriuretic peptide (NT-proBNP) was measured by bidirectional lateral flow immunoassay. The left ventricular end diastolic dimension (LVEDD), left ventricular end systolic dimension (LVESD), left ventricular ejection fraction (LVEF), and left ventricular short fraction shortening (LVFS) were measured by echocardiography. ROC curve was used to analyze the diagnostic value of serum Copeptin and MMP-9 in CHF. The correlation of serum Copeptin and MMP-9 with the cardiac function indices were examined by Pearson correlation analysis. Results The levels of serum copeptin, MMP-9, and NT-proBNP in different cardiac function groups (Ⅱ, Ⅲ, Ⅳ) increased gradually with the aggravation of the cardiac function damage and were higher than those in control group, and the differences were statistically significant (P<0.05). Compared with the control group and cardiac function grade Ⅱ group, the levels of LVESD and LVEDD were increased and the levels of LVEF and LVFS were decreased in the grade Ⅲ and Ⅳ groups. Compared with the grade Ⅲ group, the levels of LVESD and LVEDD were increased and the levels of LVEF and LVFS were decreased in the grade Ⅳ groups. There were significant differences (P<0.05). The ROC curve showed that the area under the curve (AUC) and 95％ CI of serum Copeptin, MMP-9, NT-proBNP and combinations of these three biomarkers in the diagnosis of CHF were 0.845 (0.781～0.914), 0.806 (0.736～0.883), 0.894 (0.828～0.962) and 0.925 (0.846～0.983) respectively, and the optimal thresholds were 12.5 pmol/L, 175.3 μg/L and 2037.0ng/L. The level of serum Copeptin was positively correlated with MMP-9 (r=0.807, P<0.001). Conclusion Serum Copeptin and MMP-9 may be involved in the ventricular remodeling in CHF children and they are expected to be a good indicator for the diagnosis of CHF and cardiac function.

Facing the problems of inconsistent standards and lack of standardized management procedures in the management of hospital diagnosis and surgical operation master data, the hospital redefined the metadata and data model by analyzing the data characteristics and the requirements of different application scenarios, cleaned and transformed the existing data to form a standardized unified standard for distribution, and established a complete data lifecycle management process.Finally, the consistency, integrity and controllability of diagnosis and operation data in each system could be realized, and the management level of diagnosis and operation master data could be effectively improved.

Objective:A meta-analysis was conducted to investigate the risk factors of interstitial lung disease in patients with RA to provide a reliable reference for clinical practice.Methods:Publications of the China Knowledge Network, Vipshop, Wanfang, China Biomedical Literature Database, EMbase, PubMed, and Cochrane Library databases were searched to obtain literature on cohort studies and case-control studies for risk factors for RA complicated with interstitial lung disease from the time of database creation until December 31, 2022. Literature screening, information extraction, and final quality evaluation were performed independently by two investigators. The extracted data were analyzed using RevMan 5.3 software.Results:A total of 31 studies with a total of 26 747 patients were included in this study, of which 4 799 patients(17.94%) were patients with RA complicated with interstitial lung disease. A total of 12 risk factors were obtained included: advanced age [ OR (95% CI) =1.07(1.04, 1.09), P<0.001], high age at onset [ OR (95% CI) =2.11(1.17, 3.82), P=0.010], male [ OR (95% CI) =1.95(1.34, 2.84), P<0.001], long duration of disease [ OR (95% CI) =1.10(1.08, 1.13), P<0.001], smoking [ OR (95% CI) =2.47(1.57, 4.04), P<0.001], high disease activity [ OR (95% CI) =(1.21, 2.54), P=0.003), cough [ OR (95% CI) =6.10 (2.40, 15.52), P<0.001], decreased pulmonary carbon monoxide diffusing capacity [ OR (95% CI) =0.93(0.89, 0.96), P<0.001], and high titer anti-CCP antibody [ OR (95% CI) =1.14(1.03, 1.26), P=0.010], high titer RF [ OR (95% CI) =2.37(1.70, 3.29), P<0.001], high level of immunoglobulin A [ OR (95% CI) =1.26 (1.09, 1.46), P=0.002] and high level of glycoprotein antigen 125 [ OR (95% CI) =3.66 (1.81, 7.41), P<0.001]. Conclusion:The existing evidence have shown that advanced age, high age at onset, male, long disease duration, smoking, high disease activity, cough, decreased pulmonary carbon monoxide diffusing capacity, high titer anti-CCP antibody and RF, high level of immunoglobulin A and high level of glycoprotein antigen 125 are the main risk factors for interstitial lung disease in patients with rheumatoid arthritis. However, the evidence of Raynaud's phenomenon and tumor marker CA153 as risk factors for RA complicated with interstitial lung disease is not strong, and further high-quality prospective cohort studies are needed.

Objective To discuss CT,MRI features of fibrous hamartoma of infancy (FHI) compared with pathology.Methyls Cinical data,CT and MRI findings,as well as pathological results of 15 patients with FHI were retrospectively analyzed.Results Totally,there were 17 lesions of FHI in 15 cases,including 13 cases with single lesion and 2 cases with double lesions.The lesions manifesting as subcutaneous-,skin-and mixed-type on CT or MR images accounted for 58.82％ (10/17),17.65％ (3/17) and 23.53％ (4/17),respectively.The subcutaneous-and mixed-type lesions showed " cloud sign" (including "thin-cloud sign" and "thick-cloud sign").The thin-cloud sign lesions composed mainly of mature adipose tissue,while the triphasic composition ratio of adipose,fibrous and primitive mesenchymal cells were relatively consistent in the lesions with thick-cloud sign.The skin-type lesions showed "mountain-inverted sign",which composed mainly of immature mesenchymal component.Conclusion CT and MRI features of FHI are complex,yet have certain characteristics,which can preferably reflect the histopathological features of FHI.

BACKGROUND: Given the general unavailability, common adverse effects, and complicated administration of tetracycline, the clinical application of classic bismuth quadruple therapy (BQT) is greatly limited. Whether minocycline can replace tetracycline for Helicobacter pylori ( H . pylori ) eradication is unknown. We aimed to compare the eradication rate, safety, and compliance between minocycline- and tetracycline-containing BQT as first-line regimens. METHODS: This randomized controlled trial was conducted on 434 naïve patients with H . pylori infection. The participants were randomly assigned to 14-day minocycline-containing BQT group (bismuth potassium citrate 110 mg q.i.d., esomeprazole 20 mg b.i.d., metronidazole 400 mg q.i.d., and minocycline 100 mg b.i.d.) and tetracycline-containing BQT group (bismuth potassium citrate/esomeprazole/metronidazole with doses same as above and tetracycline 500 mg q.i.d.). Safety and compliance were assessed within 3 days after eradication. Urea breath test was performed at 4-8 weeks after eradication to evaluate outcome. We used a noninferiority test to compare the eradication rates of the two groups. The intergroup differences were evaluated using Pearson chi-squared or Fisher's exact test for categorical variables and Student's t -test for continuous variables. RESULTS: As for the eradication rates of minocycline- and tetracycline-containing BQT, the results of both intention-to-treat (ITT) and per-protocol (PP) analyses showed that the difference rate of lower limit of 95% confidence interval (CI) was >-10.0% (ITT analysis: 181/217 [83.4%] vs . 180/217 [82.9%], with a rate difference of 0.5% [-6.9% to 7.9%]; PP analysis: 177/193 [91.7%] vs . 176/191 [92.1%], with a rate difference of -0.4% [-5.6% to 6.4%]). Except for dizziness more common (35/215 [16.3%] vs . 13/214 [6.1%], P = 0.001) in minocycline-containing therapy groups, the incidences of adverse events (75/215 [34.9%] vs . 88/214 [41.1%]) and compliance (195/215 [90.7%] vs . 192/214 [89.7%]) were similar between the two groups. CONCLUSION: The eradication efficacy of minocycline-containing BQT was noninferior to tetracycline-containing BQT as first-line regimen for H . pylori eradication with similar safety and compliance.
