Objective:To investigate the role of blood ammonia in the evaluation of the prognosis of septic patients in the emergency department and to compare its value with mortality in emergency department sepsis (MEDS) score.Methods:A retrospective clinical study was conducted to septic patients who were diagnosed in the Emergency Department of West China Hospital of Sichuan University from June 2017 to May 2018, and met the diagnostic criteria established by the diagnostic criteria of the American College of Chest Physicians/Society of Critical Care Medicine in 2001. The subjects who had other diseases that affected blood ammonia level and were lost to follow-up were excluded. MEDS scores were collected, and the survival status of patients was followed up by telephone. The independent samples t test was used to compare the differences between the two groups, receiver operating characteristic (ROC) curve was used to assess the accuracy of the prediction of sepsis mortality, and the logistic regression model was used to explore the value of the combined use of blood ammonia and MEDS score.Results:Eighty subjects were finally included in the study and divided into the 1-week survival group ( n=52), 1-week death group ( n=28); 4-week survival group ( n=37), 4-week death group ( n=43); 12-week survival group ( n=33), 12-week death group ( n=47); 1-year survival group ( n=32), and 1-year death group ( n=48). There was no statistical difference in the demographic characteristics of subjects between the groups. The average blood ammonia level of all the subjects who died was higher than that of the patients who survived in the same period [(116.57 ± 85.33) μmol/L vs (77.63 ± 35.82) μmol/L, (108.53 ± 73.00) μmol/L vs (71.19 ± 32.53) μmol/L, (106.74 ± 71.59) μmol/L vs (69.21 ± 28.84) μmol/L, (105.77 ± 71.14) μmol/L vs (69.50 ± 29.25) μmol/L, P<0.05]. Based on death after one week, four weeks, twelve weeks and one year, the area under ROC curve (AUC) of blood ammonia was 0.668 (95% CI: 0.542-0.793, P=0.014), 0.706 (95% CI: 0.593-0.819, P=0.002), 0.705 (95% CI: 0.592-0.818, P=0.002), and 0.697 (95% CI: 0.582-0.811, P=0.003), respectively. Compared with the use of blood ammonia, lactic acid or MEDS score alone, the combined use of blood ammonia and MEDS score increased the accuracy of prognosis evaluation in sepstic patients ( P<0.05). Conclusions:Blood ammonia has a high value in predicting the short-term and 1-year prognosis of septic patients in the emergency department. The combined use of blood ammonia and MEDS score can further improve its predictive value.

Journal of China Medical University 2017;46(10):882-886
Objective To study the effect of adhesive overflow grooves on the marginal and internal adaptation of a molar zirconia full crown.Methods A three-dimensional model of a mandibular first molar was established.Four crown preparations (A-D) were designed:a was a conventional full crown design,and B,C,and D included 1,2,and 4 adhesive overflow grooves,respectively,designed on the basis of A.Five resin preparations were created for each group using three-dimensional (3D) printing.According to the a design data,20 CAD/ CAM zirconia crowns were prepared and randomly divided into four groups.The tooth,preparations,and crowns underwent 3D scanning for 3D deviation analysis and 3D wall thickness analysis.The gap between the crown and the preparation was replicated with silicone rubber,and then observed with a metallographic microscope and measured.Data were statistically analyzed with SPSS 17.0.Results Among the groups,marginal and internal clearance was A>B>C>D.The comparison between every two groups was statistically different (P < 0.05).Conclusion Increases in the number of overflow grooves result in significant increases in the marginal adaptation and internal adaptation of a full crown.

Objective To review the etiology of fever of unknown origin (FUO) and the methods used to establish a diagnosis. Methods A retrospective review of the medical records of 317 patients with FUO admitted between January, 1996 and December, 2000 was performed. Results Of the 317 children, 298 cases (94.0%) had a definitive etiology established. Of the 298 cases, 160 (53.7%) had infectious diseases and non-infectious diseases, such as collagen vascular disease, and neoplasm which accounted for a large fraction of the remainder. A diagnosis was established in 140 (47.0%) by comprehensive clinical analysis alone. Culture of bacteria in serum and biopsy specimens established a diagnosis in 64 cases (21.5%) and 37 cases (12.4%), respectively. Non-invasive imaging techniques (35 cases; 11.7%), autopsy (11 cases; 3.7%), bone marrow examination (6 cases; 1.9%) and retrospective diagnosis (5 cases; 1.7%) accounted for the remainder of the diagnosis. Conclusions Most cases of FUO can be diagnosed by clinical characteristics of the patients and by essential laboratory studies. Pathological examination is very important in diagnosing the etiology of FUO. Infectious diseases, collagen vascular disease and neoplasm are the major causes of FUO in children.

Objective To investigate the sleep disorders status of patients with peritoneal dialysis (PD),and analyze the related factors of sleep disorders.Methods The KDQOL sleep sub-scale was used to conducted the sleep investigation in 84 PD patients.Meanwhile,the fatigue,physical activity level and depression were collected.Results The mean score of sleep sub - scale of patients was (53.12 ± 19.33 ).The prevalence of sleep disorders was 48.8%.And the logistic regression analysis showed that low physical activity level( OR =2.172,P <0.05 ),medical expenses ( OR =1.793,P <0.05 ) and depression ( OR =1.367,P <0.05) were predicted factors of sleep disorders.Conclusions More attention should be paid to sleep disorders in PD patients,promote them to take part in physical activity,take medicine or non-medicine measures to improve their quality of sleep and mental health so as to decrease the incidence of sleep disorders in PD patients.

OBJECTIVETo investigate the effect of Qianlie Huichun capsule on the microstructure and ultranstructure of prostate glandular tissue in the model rat.
METHODHynertophy of prostate model rat was established by injecting testosterone to gelding male rats. After having been fed with Qianlie Huichun capsule for 30 days, the rats were killed and prostate tissues were resected for pathomorphological studies with microscope and electromicroscope, and the diameter of glandular lumer and the height of glandular epithelial cells were measured under the microspcope for different groups of rats.
RESULTIn the model groups, the glandular epithelial cells mutiplycated notably, showing stratified and pseudostratified cells that made the glandular lumer cramped. Under the electromicroscope, the glandular epithelial cells became high columnor and the rough endoreticulum extremely expanded. But in treatment groups, the change of the diameter of the glandular lumer and the height of the glandular epithelial cells were less remarkable than those in model groups. So the differerence between the model group and the treatment groups was remarkable (P < 0.01).
CONCLUSIONQianlie Huichun capsule can depress the glandular epithelialceu multiplication of prostate gland in model rats.

Recombinant fusion protein of cholera toxin B subunit (CTB) and poly-valent protective epitopes of plasmodium falciparum was given to i. m to C57BL/6j mice and rhesus monkeys three times. In rhesus monkeys, high level of antibodies for CTB (1:6400) and malaria epitopes (1:3200) amtobpdoes were elicited as well as the specific CTL activity for P. plasmodium. After the mice were challenged with sporozoites of P. yeolli, about 50 % of them were protected from the patent infection. A blood-stage challenge with 108 of P. cynomolgi parasite were given to rhesus monkeys, which showed that two animals in control group were patent infection for at least 30 days, in contrast, the two animals immunized were recovered respectively at the day of 11 and 15 after challenges. The results suggested that cholera toxin acts as an effective adjuvent in the development of malaria vaccine.
