Objective To observe effect of abdomen compression on improvement of anal exsufflation for patients after abdomen operation. Methods Patients in the department of general surgery( 120 cases )after abdomen operations were randomly divided into the experimental group and the control group with 60 cases in each group.The control group adopted routine postoperative nursing,The experimental group received abdomen compression baaed upon routine nursing. Anal exsufflation time was compared between the two groups. Sults Anal exsufflation time of the experimental group undergoing different operations was earlier than that of the control group(P < 0.01 ). Conclusions Abdomen compression can bring forward anal exsufflation time,fa-cilitate the recovery of gastrointestinal function and normal diet, thus improve the rehabilitation of patients

Objective To study the clinic value of brain edema detected by ultrasound examination in high risk term infants. Meth-ods The study group included 140 term infants who were found having brain edema in cranial ultrasound examinations. 152 term infants with normal ultrasound scan were selected as a control group. The risk factors of brain edema were collected, and univariate analysis and multivariate logistic regression analysis were performed. Results (1) There was no difference of incidence of brain edema between the infants with or without maternal ill historys, fetal distress or hypoalbuminemia, with P > 0.05. (2) In the univariate regression model, as-phyxia,hypoxic -ischemic encephalopathy (HIE) ,ventilation and metabolic acidosis were associated with an increased risk of brain ede-ma. In the multivariate logistic regression model, HIE was associated with a greater risk of brain edema and ventilation was possibly asso-ciated with brain edema. Conclusion Brain edema detected by ultrasound examination in high risk term infants has close relationship with HIE. It suggest that there is a consistency between ultrasound results and clinic situation. The detection of brain edema by ultrasound can assist doctor in clinic practice.

Objective:To report thigh muscle magnetic resonance imaging (MRI)tests of four Chinese patients with dystrophinopathy with edema changes in adductor longus muscles that mimics adductor en-thesopathy.Methods:Four boys,who were from four unrelated families and aged from 5 to 11 years, were investigated because of the clinical manifestations including myalgia or muscle weakness or the inci-dental findings of elevated serum creatine kinase levels,and were diagnosed with dystrophinopathy by gene test of Duchenne muscular dystrophy (DMD).Their creatine kinase levels were increased from 4 087 IU /L to 32 700 IU /L (Normal range:75 -175 IU /L).The muscle biopsy of three patients all demonstrated a dystrophic pattern including necrosis,regeneration,hypertrophy,atrophy and connective tissue proliferation,with different proportions of dystrophin-negative muscle fibers.The gene test of DMD showed an out-frame deletion of exons in three of the four patients,involving either exons 45 or exons 49 -52 deletion or exon 62 duplication,and c.2665 C >T with nonsense mutation in the other one. Muscle MRI tests of the bilateral thighs were performed with T1 weighed sequence and slow tau inversion recovery sequence.The degree of fatty infiltration changes was scored.Results:MRI of the thigh mus-cles showed mild to severe fatty infiltration changes in T1 weighed sequence with the total scores from 2 to 13.The most severe fatty infiltration changes were in the long head of biceps femoris and adductor mag-nus.Obvious hyperintensities appeared mainly in the adductor longus muscles on slow tau inversion re-covery (STIR)images in all the patients without any abnormal signals in the attachment of the ligament, indicating edema changes of the adductor longus muscles which mimiced adductor enthesopathy.Two of the four patients presented with edema changes in the bilateral adductor longus muscles,while the other two were with only unilateral changes.Furthermore,other thigh muscles,including adductor magnus, semitendinosus,sartorius and rectus femoris muscles,could also have mild edema changes in two of the four patients.Conclusion:Dystrophinopathy can manifest as edema changes in the adductor longus mus-cles in thigh muscle MRI tests,which is a typical lesion in adductor enthesopathy.The adductor longus muscles in the dystrophinopathy patients may be easy to be impaired due to traction injury during sports.

OBJECTIVETo explore the role of annexin A2 (ANXA2) expression in the intestinal mucosa in the pathogenesis of inflammatory bowel disease (IBD).

METHODSIntestinal or colonic mucosal biopsy samples were obtained from 54 patients with ulcerative colitis (UC), 37 with Crohn's disease (CD), and 15 healthy control subjects. Immunohistochemistry was employed to examine the expression of ANXA2 in the intestinal mucosa, and mRNA expression of ANXA2 was detected using real-time PCR.

RESULTSImmunohistochemistry showed a ANXA2 positivity rate of 83.3% (45/54) in patients with UC, 27.0% (10/37) in patients with CD, and 53.3% (8/15) in the control subjects. ANXA2 expression in the intestinal or colonic mucosa was significantly up-regulated in patients with UC compared with the patients with CD and healthy control subjects, but was significantly lower in patients with CD than in the healthy controls (P<0.05). The expression levels of ANXA2 were strongly associated with the severity of clinical manifestations and the histopathological grades of UC (P<0.05). Compared with the healthy controls and patients with CD, patients with UC showed a significantly increased ANXA2 mRNA expression level in the inflamed mucosa of UC (P<0.05).

CONCLUSIONANXA2 can serve as a marker for differential diagnosis of IBD, and its up-regulated expression is closely related to the pathogenesis of UC.

Background and objective Lung cancer is the malignant tumor with the highest incidence rate and the heaviest disease burden in China.In recent years,lung cancer has shown a high incidence trend,seriously affecting the health of the population.In this paper,we analyze the characteristics of lung cancer incidence in 2019 and the trend of incidence rate from 2010-2019 in the tumor registration area of Gansu province,in order to provide a reference basis for the development of lung cancer prevention and control strategies in Gansu province.Methods By analyzing the cases of lung cancer incidence in the tumor registration area of Gansu province in 2019,we calculated the incidence rate,medium incidence rate,world in-cidence rate and other related indexes;we used Joinpoint to calculate the annual percentage change(APC)for trend analysis.Results In 2019,a total of 3757 new cases of lung cancer were reported in Gansu province,accounting for 14.96%of all new malignant tumors.The incidence rate,medium incidence rate and world incidence rate and world rate of lung cancer were 40.52/105,25.78/105,25.86/105;and the cumulative rate of 0-74 years old,and the truncation rate of 35-64 years old were 3.23%,40.03/105,respectively.The incidence of lung cancer rises with age,and is high in the age group of 40 years and above,and the incidence peaks in the male and female populations in the group of 75 years and above,and the group of 80 years and above,respectively.The crude incidence rate of lung cancer in the tumor registration area of Gansu province from 2010-2019 showed an overall increasing trend,and the rate of increase was relatively fast,with an APC 5.39%(P<0.05);Separately,accord-ing to gender,urban and rural areas,the incidence of lung cancer in all populations showed an increasing trend,and the APC of male,female,urban and rural populations were 4.98%,6.39%,6.26%,and 4.64%,respectively(all P<0.05).According to the trend analysis of lung cancer incidence rate by age group,only lung cancer incidence in the age group of 65 years and above increased at an annual average rate of 4.15%(P<0.05).Conclusion The incidence rate of lung cancer in the tumor registration area of Gansu province from 2010 to 2019 shows a rising trend year by year,and there are differences in the incidence of lung cancer in people of different genders,regions and age groups,so comprehensive prevention and control work should be carried out for the key populations of lung cancer incidence.
