Objective To study the clinical value of magnetically controlled capsule endoscopy in diseases screening. Method We retrospectively analyzed 61 cases which were evaluated by magnetically controlled capsule endoscopy from March 2015 to December 2016. The items include operating time, the divergence rate score and cleanliness score of stomach. The consistency was compared between magnetically controlled capsule endoscopy and gastric duodenal endoscopy. Results 61 upper gastrointestinal tract studies were included. The mean age was (49.4 ± 11.6) years. No capsule retention, perforation or bleeding occurred. There was 98.4% patients, which cleanliness of stomach was good. There was 68.9% patients, which filling degree of stomach was good. The concordance rate of the two tests of gastrduodenoscopy and magnetically controlled capsule endoscopy was 89.9% (80/89). The concordance rate of the two tests was 78.9% (15/19) in esophageal and cardia, 92.9% (52/56) in stomach, 92.9% (13/14) in duodenum. Conclusion Our experience shows that magnetically controlled capsule endoscopy is a safe and useful tool for the diagnosis of upper gastrointestinal tract disease. The detection rate is similar to gastrduodenoscopy.

Objective To examine the usefulness of shock index (Sl) and adjusted shock index (corrected to temperature) (ASI) in predicting prognosis of patients with return of spontaneous circulation after cardiac arrest.Methods A prospective study,which data such as vital signs of the cases were collected by the Utstein template,was conducted in 111 of cases with return of spontaneous circulation after cardiac arrest to assess the value of SI and ASI for predicting their prognoses.Results There was no evidence to show difference between the cases with survival to hospital discharge and the ones who died about systolic blood pressure and heart rate (P ＞0.05).SI and ASI [(1.109 ±0.428) and (1.082 ±0.410)] of the group of death were higher significantly than the ones [(0.899 ± 0.303) and (0.844 ± 0.265)] of the group with survival to hospital discharge,P ＜ 0.05.The risk of death was elevated in the group with ASI ＞ 1.1,which odds ratio (5.4) higher than the ones of systolic blood prcssure ＜90 mm Hg (1.6)and ventricular rat ＞ 100 beat/min (3.1) significantly.The odds ratio of death with AS ＞ 1 was 2.8.Conclusions Shock index and adjusted shock index are easy to derive and conducive to predict effectively diseases prognosis such as survival to hospital discharge or death of patients with ROSC.

Objective:To evaluate the changes of quality of life in patients with axial spondyloarthritis (ax-SpA) after treatment with non-steroidal anti-inflammatory drugs (NSAIDs) by the 36-item Short Form Health Survey (SF-36).Methods: 120 patients diagnosed with ax-SpA were collected in the first Affiliated Hospital of Zhengzhou University from October 2014 to September 2015.They all agreed to be treated with the special drugs and assessed by special scale.Then they all signed the agreement.In the 3 months,double-blind,parallel controlled trial patients were randomized to 200 mg twice daily (bid) imrecoxib,or 200 mg twice daily (bid) celecoxib.They were assessed for the changes of quality of life at enrollment and after three months of NSAIDs therapy by the SF-36 of Chinese edition.The correlation between quality of life and erythrocyte sedimentation rate (ESR),C-reactive protein (CRP),Bath Ankylosing Spondylitis Disease Activity Index (BASDAI),Bath Ankylosing Spondylitis Functional Index (BASFI),Spondylo Arthritis Research Consortium of Canada (SPARCC) was analyzed.Results: A total of 116 ax-SpA patients completed the study and 4 patients were lost to follow-up.We used the SF-36 scale to assess the quality of life in patients with ax-SpA before and after 3 months,NSAIDs treatment.The treatment effects were not statistically significant difference between the two drugs (P>0.05).After all the patients were treated with NSAIDs for 3 months,there was statistically significant difference (P<0.05) of the physical functioning,role-physical,bodily pain,general health,social functioning,role-emotional;and there was no statistically significant difference (P>0.05) of vitality and mental health.The positively significant correlations had been identified between BASDAI and PF,RP,BP,GH,VT,SF,RE (P<0.05),while no significant correlation was found between BASDAI and MH (P>0.05).A positively significant correlation had been identified between BASFI and PF,RP,BP,GH,SF,RE,MH (P<0.05),while no significant correlation was found between BASFI and VT (P>0.05).The ESR was positively correlated with SF,RE (P<0.05);and CRP was positively correlated with SF,MH (P<0.05);and SPARCC was positively correlated with PF (P<0.05).BASDAI and BASFI were the important influence factors of PF (P<0.05);and BASDAI was the important influence factor of BP,GH,VT,RE(P<0.05);BASFI was the important influence factor of RP,SF,MH(P<0.05).Conclusion: Non-steroidal anti-inflammatory drugs can improve the quality of life of the ax-SpA patients.Imrecoxib and celecoxib have the equivalent curative effect.SF36 scale is suitable for the assessment of the quality of life in patients with ax-SpA.

Aim Toinvestigatetheeffectsoftriptonot-erpene methyl ether ( TME ) , a diterpene derived from the medicinal plant Triptergium wilfordii, on human gastric cancer AGS cell proliferation inhibition and ap-optosisinducedinvitro.Methods MTTassaywas used for screening tumor spectrum and detecting the vi-ability of AGS cells and normal human gastric epitheli-al cells GES-1 . Cell morphology was observed by light microscopy and AO / EB staining. Flow cytometry was used to detect cell apoptotic rate and cell cycle. JC-1 staining and fluorescence probe DCFH-DA were em-ployed to detect the changes of mitochondrial mem-brane potential and reactive oxygen species ( ROS ) . The effect of inhibiting AGS clonogenic survival was as-sayed by the method of plate clone formation. Western blot was used to analyse the expression of caspase-3 , caspase-8,Bcl-2andBax.Results MTTresults showed that TME exhibited significantly higher cytotox-icity to gastric cancer AGS cell line than to noncancer-ous cell line GES-1. IC50 for AGS of 48 h treatment was 23 . 85 μmol · L-1 . TME significantly inhibited colony formation and caused morphological changes in AGS cells. Annexin V-FITC / PI double staining showed the apoptotic rate increased. DCFH-DA stai-ning showed TME resulted in an increase in intracellu-lar ROS levels. Mitochondrial membrane potential de-creased after TME treatment. Western blot results showed that TME increased the proportion of Bax /Bcl-2 , with the activation of caspase-8 and caspase-3 . The broad-spectrum caspase inhibitor z-VAD-fmk pre-treatment reduced the expression of caspase-8 and caspase-3. TME enabled AGS cell cycle arrest in G0/G1phase.Conclusion TMEpossessespotenttumor selected toxicity and can induce apoptosis of AGS cells through cell cycle arrest, which is associated with Bcl-2 protein family.

Objective To analyze the clinical characteristics of respiratory involvement in relapsing polychondritis(RPC). Methods The clinical data of 38 patients with respiratory (larynx, trachea and bronchus) involvement in RPC were retrospectively analyzed. Results The incidence of respiratory involvement in patients with RPC was 51.35%(38/74), and the most common symptoms were cough, wheezing, chest tightness and dyspnea. The incidences of erythrocyte sedimentation rate (ESR) increasing, C- reactive protein (CRP) increasing, fibrinogen increasing, D- dimer increased and rheumatoid factor (RF) positive in patients with respiratory involvement were significantly higher than those in patients without respiratory involvement: 47.37% (18/38) vs. 30.56% (11/36), 52.63% (20/38) vs. 33.33% (12/36), 31.58% (12/38) vs. 25.00% (9/36), 21.05% (8/38) vs. 13.89% (5/36) and 36.84%(14/38) vs. 5.56% (2/36), and there were statistical differences (P<0.05). CT was the main method to discover the respiratory involvement, and MRI could detect early cartilage inflammation lesions. Laryngoscope and bronchoscope could early detect mucosa and cartilage damage. Pathology was given priority to lymphocytes and neutrophils infiltration. Some patients had epithelium metaplasia and even canceration. Primary treatment methods were glucocorticoids combined with immunosuppressant. Airway stenosis and infection was the main factors influencing the prognosis of patients. Conclusions The respiratory involvement is not uncommon in RPC, and early CT, MRI, laryngoscope and bronchoscope examination is an important means of early diagnosis.Early glucocorticoid combined immunosuppressive therapy is the key to achieve good prognosis.

Objective: To describe the epidemiological characteristics of suicide death and self-harm/suicide in China from 2006 to 2016. Methods: Data in this study are from the datasets of National Death Cause Surveillance from 2006 to 2016 and the National Injury Surveillance Dataset 2016. The age-standardized death rate based on the population census in 2000 was used to describe the trend of suicide over years. This study also described the epidemiological characteristics of suicide death and the demographic characteristics, suicide methods and severity of patients who sought medical help after committing suicide or self-inflicted injury in 2016. Results: Age-standardized suicide mortality had been declining from 9.23/100 000 in 2006 to 5.33/100 000 in 2016 by 42.25%. Suicide mortality increased with age. In 2016, the suicide mortality in China was 7.05/100 000, and among people over 85 years old was 49.49/100 000. In 2016, the dominant two suicide methods were poisoning (39.12%) and sharp injury (25.62%). The first leading method of suicide in rural population, urban population and young people aged 10-to 17-year-old was poisoning (65.13%), sharp injury (29.90%) and fall (25.47%), respectively. As age increased, the severity of suicide/self-inflicted injury increased. The proportions of serious cases among young people aged 10-to 17-year-old and older people aged 60 years old and above who sought medical help after committing suicide or self-inflicted injury were 4.88% and 26.86%, respectively. Conclusion China′s suicide mortality has been declining and special attention should be given to the suicide of old people.

Objective: The present study aimed to examine the mediated moderation effect underlying the association between parental psychological aggression and phubbing, as well as the mediating role of anxiety and moderating role of sex and grade. Methods: Based on a cross-sectional study, a total of 758 Chinese junior high school students had completed measures on socio-demographic characteristics, parental psychological aggression, anxiety and phubbing. Structural equation modeling was adopted to examine the mediating effect of anxiety on the association between parental psychological aggression and phubbing. Multigroup analyses were conducted to explore whether the path coefficients differed by sex and grade. Results: Mediation analysis indicated that anxiety could mediate the association between parental psychological aggression and phubbing. The indirect effect of parental psychological aggression on phubbing via anxiety was 0.12. Multigroup analyses revealed that the higher mediation effect of anxiety was more likely to be reported by boys and students from grade eight. Conclusion Findings of the present study may inform prevention and intervention programs for phubbing in adolescents exposed to parental psychological aggression, by decreasing the anxiety and adopting selective strategies for different sex and grade groups.
