Bidirectional relationship between nonalcoholic fatty liver disease and sarcopenia： New insights and perspectives / 临床肝胆病杂志

‍Nonalcoholic fatty liver disease （NAFLD） is a group of highly heterogeneous diseases closely associated with metabolic dysfunction. Sarcopenia is a syndrome caused by a continuous decline in muscle mass， strength， and function， and it is often accompanied by NAFLD. Insulin resistance is the main pathological mechanism for sarcopenia and NAFLD， and in addition， factors such as changes in proteins and branched‍-‍chain amino acid， hyperammonemia， intestinal flora， and endocrine dysfunction can also lead to sarcopenia and NAFLD. With the deepening of clinical research， many published prospective studies have confirmed the existence of a bidirectional and complex pathophysiological relationship between sarcopenia and NAFLD. This article reviews the bidirectional relationship between sarcopenia and NAFLD， discusses the common pathogenesis of sarcopenia and NAFLD， summarizes the challenges faced in this field， and proposes new directions for the research on the bidirectional relationship between NAFLD and sarcopenia.

The diagnostic value of different methods for detecting constipation with defecation disorder based on Roman Ⅳ criteria / 西安交通大学学报(医学版)

【Objective】 To study the diagnostic value of balloon expulsion test, anorectal manometry, and colonic transit test for detecting constipation with defecation disorders. 【Methods】 Outpatients with functional constipation were retrospectively analyzed and classified into dyssynergic defecation constipation and non-dyssynergic defecation constipation according to the Rome Ⅳ diagnostic criteria. We studied the differences in symptomatological characteristics and results of the three testing methods between the two groups of patients. 【Results】 Among the 48 patients with functional constipation included, there were 13 males (27.1%) and 35 females (72.9%) with an age of (44.8±12.3) years, including 32 patients (66.7%) with defecation disorder and 16 patients (33.3%) with non-defecation disorder. The percentage of anal distension was significantly higher in patients with dyssynergic defecation constipation than in those with non-dyssynergic defecation constipation (34.4% vs. 0.0%, P=0.021). All the three tests had diagnostic value for dyssynergic defecation constipation, but with low diagnostic agreement between the results of each test. The diagnostic sensitivity of anorectal manometry was 100%, but the specificity (56.3%) was low, and both the positive predictive value (82.1%) and the negative predictive value (100%) were higher; the diagnostic sensitivity (75.0%) and specificity (81.3%) of the balloon expulsion test were both higher. The Youden index of colonic transit test was the smallest. The anal resting pressure and maximum systolic pressure of dyssynergic defecation constipation were lower than those of non-dyssynergic defecation constipation (75.2 mmHg vs. 97.1 mmHg, 168.7 mmHg vs. 251.6 mmHg). The two types of constipation did not significantly differ in anorectal pressure gradients during simulated defecation or rectal sensory function. 【Conclusion】 The balloon expulsion test can be used as a primary screening test for constipation with defecation disorders, and anorectal manometry has the highest comprehensive diagnostic value, but there is a certain false positive rate, and the colonic transit test has the lowest diagnostic efficacy. Thus a comprehensive analysis of the patient’s symptoms and the results of different tests is needed in clinical practice.

Application of cognitive education in esophageal high resolution manometry examination / 中国实用护理杂志

Objective To explore the effect of cognitive education and behavioral intervention in solid-state high resolution esophageal manometry (HRM) examination. Methods From April 2016 to June 2017, 60 patients with solid-state HRM in the gastrointestinal motility room at the First Affiliated Hospital of Jiaotong University were as the research object. The 60 patients were divided into control group and experimental group with 30 cases each by the method of random numbers. The conventional methods was used in control group to conduct informed counseling before the examination and the coordination guidance in the examination. The conventional methods and cognitive behavioral intervention was used in experimental group at the same time. The successful rate of intubation, the time used for the examination, discomfort symptoms during intubation, the patient's satisfaction in the whole check process and self-evaluation of intubation pain experience in two groups of patients were compared. Results The time used in the experimental group examination was (28.50±8.75) min, and the control group was (33.13± 5.49) min. The difference between the two groups was statistically significant (t=2.584, P=0.015). In the experimental group, the number of nausea, vomiting, and coughing in the intubation process was 11, 0, and 1, respectively, and the control group was 20, 6, and 7, respectively. The difference was statistically significant (χ2=5.406, 4.630, 5.192, all P<0.05). In the experimental group, the scores of the 2, 3, 4, 5, 7, 8, 10, 11, 12, and 13 items of the intubation pain experience self-evaluation in the examination process were (1.00 ± 0.64), (1.37 ± 0.85), (2.80 ± 0.96), (1.50 ± 0.51), (0.87 ± 0.63), (0.77 ± 0.50), (0.60 ± 0.56), (1.07 ± 0.25), (0.57 ± 0.57), (1.50 ± 0.63) points, and the 2, 3, 4, 5, 7, 8, 10, 11, 12 and 13 scores of the control group they were (1.50 ± 0.51), (2.03 ± 0.76), (3.50 ± 0.82), (2.03 ± 0.76), (1.20 ± 0.61), (1.03 ± 0.41), (0.83 ± 0.53), (1.23 ± 0.43), (0.87 ± 0.57), (2.00 ± 1.05) points, respectively. The difference was statistically significant (t=-4.130--2.140, all P<0.05). Conclusions HRM is an important test before the clinical application of a wide range of clinical applications for the detection of esophageal motility disorders and gastroesophageal reflux disease. The degree of patient cooperation with the operation directly affects the high-resolution esophageal manometry test results and self-experience. Medical staff can give patients cognitive education and behavioral intervention before examination, which can effectively reduce the symptoms and pain caused by intubation, improve patient compliance, shorten the time for examinations, improve work efficiency, and improve patient satisfaction. It is worth further promotion and application in clinical examination.

Evaluation of subclinical left ventricular systolic dysfunction in patients with severe aortic stenosis by three dimensional speckle tracking echocardiography / 中国医师杂志

Objective To evaluate the role of three dimensional (3D) speckle tracking echocardiography (STE) in detection of subclinical left ventricular (LV) systolic dysfunction in patients with aortic stenosis (AS).Methods The study included 47 patients with AS and 50 age-matched healthy individuals.Conventional echocardiographic parameters were measures,and 3D Speckle tracking imaging of the peak systolic strain was recorded.Results Three-dimensional global longitudinal strain (3D-GLS) were significantly reduced in patients with AS compared to controls (P ＜ 0.01).Three-dimensional global circumferential strain (3D-GCS) were significantly increased (P ＜ 0.05).Three-dimensional global area strain (3D-GAS) and three-dimensional global radial strain (3D-GRS) were similar between two groups (P ＞0.05).Correlation analysis showed that |3D-GLS| was negatively correlated with left ventricular mass index (LVMI) (r =-0.59,P ＜0.05) irrespective of |3D-GAS|,|3D-GCS|,3D-GRS,and left ventricular ejection fraction (LVEF).Conclusions Patients with AS have evidence of subclinical LV systolic dysfunction despite preserved EF％.3D speckle tracking appears is useful in detection of subclinical LV dysfunction in patients with AS.

Effect and safety of Endoscopic retrograde appendicitis therapy in treating patients with uncomplicated acute appendicitis / 中国内镜杂志

Objective To study the effect and safety of endoscopic retrograde appendicitis therapy (ERAT) in treating patients with uncomplicated acute appendicitis. Methods Patients with uncomplicated acute appendicitis were enrolled and divided into ERAT group and LA group received laparoscopic appendectomy. Then compare treat-ment condition, complications and follow-up of the two groups. Results ERAT were completed successfully in all the patients in ERAT group, while one patient underwent a reversion to open appendectomy for technical difficulties in LA group. Mean operative time was (49.7 ± 18.2) min for ERAT group and (68.9 ± 25.9) min for LA group (P <0.05). Fever relief time (1.3 ± 0.5) d, WBC normalization time (2.0 ± 0.9) d, mean bed time (0.1 ± 0.2) d and mean hospital stay (3.3 ± 1.6) d for ERAT group were significantly lower than LA group (P <0.05). 14 patients with intra-luminal appendicoliths (7 of massive appendicoliths, 4 of broken appendicoliths and 3 of broken appendicoliths with luminal stenosis) underwent endoscopic lithotomy successfully in ERAT group, resulting in a success rate of 100.00%. One patient presented perforation after ERAT was cured with conservative treatment. During the follow-up of at least 1/2 year, the rate of recurrence was 10.00% in ERAT group. 1 patient (5.00%) underwent LA at the 5th month after ERAT during the follow-up. Conclusion ERAT is an effective and safe therapy in treating patients with uncomplicated acute appendicitis with advantages of minimal invasiveness and quick recovery. Uncomplicated acute appendicitis with appendicoliths and/or luminal stenosis are the most suitable indications for ERAT.

Relationship between Complications and Neurologic Subtype or Gross Motor Function in Preterm Infants with Cerebral Palsy / 中国康复理论与实践

@#Objective To investigate the distribution of complications and the relationship with neurologic subtype and gross motor function in preterm infants with cerebral palsy (CP). Methods The type, grade of Gross Motor Function Classification System (GMFCS), intelligence,speech, ophthalmologic consultation, brainstem auditory evoked potential and electroencephalogram of 135 preterm infants with CP were reviewed. Results There were 284 complications in total, (2.10±1.33) per child, and was significantly different among various types of CP (F=5.50, P<0.001). The incidence of mental retardation and speech disorder was significant different among various types (P<0.05). The incidence of mental retardation, speech disorder, visual impairment and epilepsy increased significantly (P<0.05) in spastic quadriplegia infants,compared with those with diplegia and hemiplegia. The incidence of mental retardation, speech disorder, visual impairment and musculoskeletal disorder was significantly different (P<0.05) among various grades of GMFCS. The frequency of complications was more in children unable to walk (GMFCS Ⅳ~Ⅴ) than able to walk (GMFCS Ⅰ~Ⅲ) for children over 2 years old (t=70.05, P<0.001). Conclusion The incidence of mental retardation, speech disorder, visual and hearing impairment, secondary musculoskeletal disorder and the multiple disorders are related with neurologic subtype and/or the grade of GMFCS.
