Objective To explore the correlation of pulse pressure(PP) and outcome in refractory septic shock patients.Methods A total of 68 patients with refractory septic shock consecutively admitted in our ICU from January 2012 to December 2012 were retrospectively studied.Hemodynamic data and arterial lactate concentration were collected at the time of admission and 24 hours after admission.The outcome of Day 28 post-diagnosis was also recorded.Results (1) Compared with the survivors,heart rate(HR) at 24hours after admission was higher in non-survivors,while 24 h lactate clearance rate (rLac) was lower in them (P ＜ 0.05).Other hemodynamic parameters showed no difference between the non-survivors and the survivors at 24 hours after admission,including central venous pressure (CVP),mean arterial pressure (MAP),systolic blood pressure(SBP),diastolic blood pressure(DBP),PP,pulse pressure/heart rate (PP/HR),pulse pressure/mean arterial pressure(PP/MAP),pulse pressure/systolic pressure(PP/SBP),pulse pressure/diastolic pressure (PP/DBP),the value of SBP above MAP (SMP) and the value of DBP below MAP(MDP).(2)The mortality rate was higher in the patients with HR≥100 b/min than those with HR ＜ 100 b/min,but without statistical significance (56.25％ vs 36.11％,P =0.096).Compared with the survivors,no matter with HR≥100 b/min or HR ＜ 100 b/min,lactate(Lac) at the 24 hours after admission was higher in all the non-survivors (P ＜ 0.05),while with lower rLac (P ＜ 0.05).In those with HR ≥100 b/min,the following hemodynamic parameters were higher in the non-survivors than in the survivors,including PP,PP/HR,PP/MAP,PP/SBP,PP/DBP,SMP and MDP (all P values ＜ 0.05),while no statistical difference was observed in those with HR ＜ 100 b/min.(3)The mortality rate showed no statistical difference in those with MAP≥85 mmHg(1 mmHg =0.133 kPa) and with MAP ＜ 85 mmHg(42.42％ vs 48.57％,P =0.611).No matter MAP≥85 mmHg or MAP ＜ 85 mmHg,compared with the survivors,all the non-survivors had higher Lac at the 24 hours after admission (P ＜ 0.05),while with lower rLac (P ＜ 0.05).In those with MAP≥85 mmHg,HR was higher in the non-survivors than the survivors (P ＜ 0.05).In those with MAP ＜ 85 mmHg,compared with the survivors,the non-survivors had higher PP,PP/MAP,PP/SBP,PP/DBP,SMP and MDP (P ＜0.05),while with lower DBP (P ＜0.05).Conclusion PP is correlated with the outcome in refractory septic shock patients.When the HR and MAP differ,PP has different effect on the outcome and contributes more to the tissue perfusion and outcome in those with higher HR and lower MAP.

Objective To establish a method for the rapid detection of hepatitis E virus (HEV)from serum samples based on fluorescence quantitative PCR.Methods (1 )One-hundred HEV sequences including our country popular three major genotypes were obtained from the GeneBank with the Vector NTI software.The proper sequence was selected to design and synthesize the primers of the fluorescence quantitation and the Taqman probe.(2)The amplification region PCR fragment was transcribed in vitro to synthesize cRNA standard,at the same time the trace serum virus lysate was introduced into a universal real-time TaqMan PCR assay.(3)10 clinical serum samples were collected from the patients with clinical hepatitis E and detected by using the established method for further verifying this method.Results This detection technique could effectively detect the serum samples in the pa-tients with genotype I and genotype IV hepatitis E positive,while the serum detection in the patients with other virus infectious dis-eases had the negative results,which verified that this RT-PCR detection technique had higher specificity and good reliability.The detection results from 10 clinical serum samples further verified that this method was rapid,convenient and sensitive with good re-peatability.Conclusion A fluorescence quantitative RT-PCR detection technique suitable for detecting main genotypes of HEV in China population is established,which can meet the demand of early and rapid diagnosis for HEV.

Objective To analyze the voice quality of children post operation for complete cleft palate through subjective and objective evaluation and explore the correlation between them. Methods Electroglottography analysis was used in the natural sound/a/of 30 postoper-ative children with complete cleft palate and 34 normal children, and the difference was compared. The natural prolonged sound/a/was as-sessed with GRBAS (grade, roughness, breathiness, asthenia, strain) in the children with complete cleft palate, and the correlation between the subjective and objective results was analyzed. Results F0, harmonic to noise ratio (HNR) were less, and the shimmer, jitter, normalized noise energy (NNE) and nasalance was greater in postoperative children with complete cleft palate than in normal children. For the children with complete cleft palate, G and R mainly rated as levels 1 and 2, B also rated as levels 1 and 2 in less than half of the children. There were low or very low correlation between all subjective and objective results, excepted G, R, B and F0, which showed moderate correlation. Con-clusion The vocal cords vibrate slowly and irregularly in postoperative children with complete cleft palate, suggesting mild and moderate voice disorder, and they sound hoarsely with roughness and breathiness. There are poor correlations between the subjective and objective as-sessment, and need to be used in combination for the children with complete cleft palate.

Objective To study the efficacy and mechanism of compound Tripterygium hypoglaucum Hutch (THH) on photoallergic contact dermatitis in mice. Methods The photoallergic animal model of BALB/c mice was established by using photosensitizer chlorpromazine and UVA irradiation. The therepeutic efficacy was determined by measuring the thickness and the weight of the swelling ear and the number of infiltrated mononuclear cells in the ear tissue. Immunohistochemical technique was used to detect the ICAM-1 expression on keratinocytes, fibroblasts and vascular endothelial cells. The serum level of INF-? was measured by ELISA. The tested animals were divided into 3 groups: compound THH, THH alone and normal saline. Results The difference of the thickness of left ear before and after challenge, the differences of the thickness and the weight of ear tissue, the difference of the number of infiltrated mononuclear cells of left and right ear after challenge were significantly less in the compound THH group than those in the THH alone group (P

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.

Objective To understand the readiness of gynecological wards in conducting the evidence-based practice for the prevention and management of urinary retention after cervical cancer radical resection,and to analyze the influencing factors.Methods The 190 nursing staffs in the gynecological oncology wards of this hospital in June 2020 were selected as the study subjects.The assessment of readiness for evidence-based nursing practice (CREBNA) and general information questionnaire were used to conduct the questionnaire survey,single factor and multiple factor stepwise regression to analyze the influencing factors.Results The score of CREBNA was (135.94±17.83) points,the evidence subscale was (52.41±7.88) points,the organi-zational environment subscale was (40.58±5.01) points and the promoting factors subscale was (42.67±6.24) points.The results of univariate analysis showed that the total score of CREBNA was related to the ed-ucational background,professional title,position,scientific research experience,understand degree on evidence-based and necessity of conducting evidence-based (P<0.05).The multiple stepwise regression analysis showed that the understanding degree on the evidenced-base and necessity of conducting evidence-based were the influencing factors of CREBNA scale (P<0.05).Conclusion The readiness of the evidence-based nursing practice in this study is good and has good feasibility.

To investigate the impact of goal directed analgesia on the outcome of patients with mechanical ventilation in intensive care unit. A total of 126 patients who needed mechanical ventilation were recruited. With a method of before and after paired comparison, they were divided into two group:( 1 ) analgesia with empirical administration or control group; ( 2 ) goal directed analgesia based on critical-care pain observation tool (CPOT). Compared with the control group, after goal directed analgesia was applied, the consumption of midazolam significantly dropped from ( 368. 47 ± 27. 41 ) mg to ( 151. 27 ± 29. 31 ) mg (P<0. 05), whereas the consumption of dexmedetomidine significantly increased from ( 623. 62 ± 20. 91) μg to (812. 34 ± 22. 57) μg(P<0. 05). The median score of Richmond agitation-sedation scale increased from -3 to -1. The incidence of delirium significantly reduced from 23. 81% to 17. 46%( P<0. 05). The mean ventilator duration was significantly shortened from (168. 49 ± 11. 41) h to (142. 38 ± 13. 24) h(P<0. 05). ICU length of stay was significantly shortened from (23. 64 ± 9. 26) d to (19. 63 ± 8. 46) d ( P < 0. 05 ) . Due to the mild sedation, patients receiving goal directed analgesia report less delirium, less ventilation time and shorter ICU length of stay, suggesting that the general outcome is improved.

ObjectiveTo discuss the diagnosis, assessment and rehabilitation for children with cerebral palsy complicated with speech disorder based on the tools of World Health Organization Family of International Classifications (WHO-FICs). MethodsThe diagnosis of speech disorder after cerebral palsy was classified using International Classification of Diseases, 11th Revision (ICD-11). The disorders of speech function were classified using International Classification of Functioning, Disability and Health (ICF). A structured speech function rehabilitation solution was developed based on the International Classification of Health Interventions (ICHIβ-3). ResultsAccording to ICD-11, cerebral palsy was classified as 08 Neurological Disorder, which was further classified as 8D20.0 Spastic Unilateral Cerebral Palsy and 8D20.1 Spastic Bilateral Cerebral Palsy (8D20.10 Spastic Quadriplegic Cerebral Palsy and 8D20.11 Spastic Bilateral Cerebral Palsy), with the speech disorders involving 6A00 Disorders of Intellectual Development, 6A01 Developmental Speech or Language Disorders, MA80 Speech Disturbances, MA81 Speech Dysfluency and MA82 Voice Disturbances. For ICF, the speech disorders mainly involved s1 structures of the nervous system, s3 structures invoved in voice and speech, b3 voice and speech functions, d1 learning and applying knowledge, and environment and individual factors; and could be further classified as b310 voice functions, b320 articulation functions, and b330 fluency and rhythm of speech functions. Based on ICHIβ-3, a rehabilitation solution was developed, involving the areas of body structure and function, activity and participation, and environmental factors. ConclusionBased on ICD-11, ICF and ICHIβ-3, a methodological system of assessment and interventions for speech disorders after cerebral palsy has been systematically constructed, including diagnosis of disease, assessment, intervention and coding of speech disorder.
