OBJECTIVE: To study the risk factors for severe acute pancreatitis (SAP) complicated by pancreatic encephalopathy (PE). METHODS: Clinical data from 255 patients with SAP from January 2005 to December 2006 were reviewed. Thirty-one SAP patients had PE, and 224 SAP patients did not. Clinical characteristics of SAP patients in both PE group and non-PE group were analyzed. RESULTS: Ranson scale and the incidence rates of acute respiratory distress syndrome (ARDS), renal failure, hypoproteinemia, hypocalcemia and hyperglycosemia in PE group were higher than those in non-PE group (P<0.05). There were no significant differences in acute physiology and chronic health evaluation II and CT severity index scales, the activities of amylase and lipase, the incidence rate of liver function failure, the infection rate and the operability between the PE group and the non-PE group (P>0.05). Multivariate logistic regression analysis showed that ARDS and hyperglycosemia were high risk factors. Cure rate in PE group was higher than that in non-PE group. CONCLUSION: Nosogenesis of PE is the result of multiple factors. ARDS and hyperglycosemia may be the high risk factors for PE.

Objective To analyze the efficacy and safety of tirofiban treatment combined with percutaneous coronary intervention (PCI) in the elderly with acute ST segment elevation myocardial infarction prospectively. Methods From May 2008 to May 2010, 106 patients who presented with acute STEMI within 12 hours from onset and received successful primary PCI were enrolled into the study. All patients had angiographic evidence of initial total occlusion of infarct-related artery and finally restored toTIMI3 flow after PCI. All patients were divided into tirofiban group (n = 54) and control group (n = 52) according to whether tirofiban was used or not. Assessment of myocardial perfusion included Myocardial Blush Grades (MBG), and the resolution of the sum of ST-segment elevation (sumSTR) at 90 minutes after the procedure. Left ventricular ejection fraction (EF) was measured one week later. Major adverse cardiac events in hospital and bleeding complications were also assessed. Results Baseline clinical and angiographic characteristics of the two groups were similar. Significant higher rates of MBG 3 were observed in the tirofiban group (88. 9% vs57. 7%, P ＜ 0.05). Patients received tirofiban were more likely to achieve higher sumSTR (70. 3% vs 42. 3%, P ＜0. 05). Ejection fraction was also markedly increased in tirofiban group than control group (56. 2 ± 7.6 vs 46. 7 ± 8. 5, P ＜ 0. 05). In-hospital major adverse cardiac events, it was not different between the two groups(P ＞0. 05). There were slightly more minor bleeding complications in tirofiban group compared with control(11.1% vs 6. 0%, P ＞0. 05). No patient had major bleeding or thrombocytopenia.Conclusions Tirofiban can further ameliorate microvascular perfusion and it is safe and feasible for patients with STEMI undergoing primary PCI.

Objective　By exploring the function of sulfakinin (SK) and sulfakinin receptor (SKR) of Aedes aegypti, it laid a certain experimental basis and theoretical basis for the research and development of new insecticides targeting neuropeptides and their receptors. Methods　This study investigated the roles of SK and its receptor gene in Ae. aegypti using bioinformatics analysis and Clustered Regularly Interspaced Short Palindromic Repeats(CRISPR)/Cas9 knockout technology. Subsequently, RNA interference technology was employed to suppress the expression of SK or its receptor in adult mosquitoes. Lastly, transcriptome sequencing technology was utilized to identify and analyze differentially expressed genes between the interference group and the control group in order to gain insights into their functions. Results　It was found that there is only one SK receptor in Ae. aegypti. In addition, during the construction of mutant strains of Ae. aegypti SK and its receptor gene, it was found that only 2% of the G0 generation mutant strains mutated to form chimeras, with a large number of male chimeras dying, and only 14% of female chimeras being able to lay eggs, ultimately resulting in no effective G1 generation mutants. Transcriptome data showed, compared to the control group, 181 genes were significantly differentially expressed after interfering with the SK gene, with 62 genes significantly upregulated and 119 genes significantly downregulated. In addition, after interference with the sulfakinin receptor, 110 genes exhibited significant differential expression, including 20 upregulated and 90 downregulated genes. Cross-analysis of the two datasets identified 46 genes with significant expression changes after interference with sulfakinin or its receptor, with only 4 genes upregulated and the remaining 42 genes significantly downregulated, and the differentially expressed genes were mainly enriched in the metabolic pathway, endocrine system, and digestive system. Conclusions　The SK and its receptor gene are highly conserved and may primarily play roles in regulating the energy metabolism and digestion functions in Ae. aegypti, thus playing an important role in regulating insect growth and development.

Objective: To explore the effect of mouth muscle training game on salivation cerebral palsy children. Methods: Sixty-eight children with cerebral palsy combined with salivation were randomly divided into experimental group and control group, with 34 cases in each group. The control group received routine rehabilitation treatment, while the experimental group performed oral muscle training game on the basis of the control group. Both the two groups were assessed by teacher salivation grading (TDS) and oral motor function assessment grading standards before and 8 weeks after intervention for salivation and oral motor function of cerebral palsy children. Results: After 8 weeks of intervention, there were 30 children with grade III-V salivation turned to grade I-IV in the experimental group, and 21 children with grade III-V salivation turned to grade I-IV in the control group, with the total effective rate of TDS of 88.2%(30/34) and 61.8%(21/34), respectively, and there was statistically difference (χ²= 5.02, P<0.05). The score of oral transport function in the experimental group was 87.68±12.93, which was higher than that of 76.53±10.92 in the control group, and there was statistically differences (t=3.841, P<0.01). Conclusions Oral muscle training games can stimulate self-exploration and training for oral movement of cerebral palsy children, so as to improve the range, flexibility and strength of the jaw, lip and tongue movement, and promote the self-control of swallowing of saliva, reduce the salivation and improve the quality of life.

{L-End}Objective To explore the interaction between social psychology and workload factors on neck work-related musculoskeletal disorders (WMSDs) in manual workers. {L-End}Methods Manual workers in Henan Province and Hubei Province were selected as the research subjects using typical sampling method. The Chinese Musculoskeletal Questionnaire was used to investigate the prevalence of neck WMSDs in the research subjects. A total of 4 327 workers with neck WMSDs were selected as the case group, and 4 327 workers without neck WMSDs were selected as the control group in a 1∶1 pairing. Conditional logistic regression analysis was used to compare the relevant risk factors in the two groups, and the additive interaction model was established to analyze the interactions between the risk factors. {L-End}Results The univariate conditional logistic analysis results showed that dynamic load, static load, power load and psychosocial factors increased the risk of neck WMSDs in manual workers (all P<0.05). In terms of the social psychological factors, insufficient rest time had the greatest impact workers, with the odds ratio (OR) and 95% confidence interval (CI) of 1.799 (1.647-1.965). In terms of dynamic load, static load and power load, repeated similar movements of the head per minute (bending, twisting), forward bending of the neck or maintaining this posture for a long time, and lifting heavy objects>20 kg had the greatest impact, with the OR and 95%CI of 1.599 (1.470-1.739), 1.984 (1.805-2.181) and 1.241 (1.093-1.408), respectively. There was a synergistic interaction between insufficient rest time and forward bending of the neck or maintaining this posture for a long time, and the relative excess risk due to interaction (95%CI) and attributable proportion (95%CI) were 0.420 (0.187-0.652) and 0.171 (0.066-0.276), respectively. There is no interaction between insufficient rest time and repeated similar movements of the head per minute (bending, twisting), and lifting heavy objects >20 kg. {L-End}Conclusion The interaction between insufficient rest time and forward bending of the neck or maintaining this posture for a long time (static load) can increase the risk of neck WMSDs in manual workers, which is an additive synergistic effect.

Objective:To explore the effect of International Classification of Functioning, Disability and Health, Children and Youth Version (ICF-CY) framed oral motor therapy combined with acupoint massage intervention on children with cerebral palsy swallowing disorder.Methods:From September 2018 to September 2019, 80 children with cerebral palsy accompanied by dysphagia who were diagnosed and treated in the Department of Neurological Rehabilitation of our hospital were selected as the study subjects, and were divided into the experimental group (40 cases) and the control group (40 cases) by random number table method. A total of 76 patients completed the study. On the basis of routine swallowing training and oral movement intervention, the experimental group was comprehensively evaluated from the aspects of body function and structure, activity and participation, and environmental factors with ICF-CY theory as the framework, and was given oral and facial acupoint massage for 12 weeks. The control group was given conventional swallowing training and oral exercise intervention for 12 weeks. The modified water swallow test was used to evaluate the effect of improving swallowing disorder in two groups of children after 12 weeks of intervention. The improvement of oral motor function in two groups of children after 4 and 12 weeks of intervention was evaluated by using the Grading Criteria for Evaluation of Oral Motor Function.Results:After 12 weeks of intervention, the total effective rate of swallowing disorder improvement in the experimental group and the control group were 89.47% (34/38) and 63.16% (24/38), respectively, and the difference between the two groups was statistically significant ( χ2 value was 7.28, P<0.05). After 4 and 12 weeks of intervention, the functional scores of oral motors in the experimental group were (67.13±2.35) and (82.08±2.33) points, respectively, which were higher than those of the control group at the same time (56.16±2.57) and (65.63±2.54) points, and the differences were statistically significant ( t values were -3.320, -4.433 P<0.05). After 4 and 12 weeks of intervention, the children's functional scores of oral motors in each group were higher than those in each group before intervention. Compared with the group before intervention, t values of the experimental group were -5.377 and -5.376; t values of the control group were -10.715 and -17.486; compared to the group with 4-week intervention, t value of the experimental group was -12.732; t value of the control group was -13.281, all the differences were statistically significant (P<0.05). The results of repeated measures analysis of variance showed that the time effect, grouping effect, and the interaction between time effect and grouping effect of functional scores of oral motors were statistically significant ( F values were 426.780, 9.084, 26.538, P < 0.05). Conclusions:Oral motor therapy combined with acupoint massage based on ICF-CY framework can effectively promotes the recovery and reconstruction of mouth perception and motor function in children with cerebral palsy, significantly improves the children's dysphagia and their ability to actively participate in feeding.

Objective:To investigate the prevention effect of nurse-led peer support system on the postpartum posttraumatic stress disorder of primipara.Methods:A total of 74 cases of primipara were randomly divided into experimental group ( n=37) and control group ( n=37). The control group received routine nursing. The experimental group received nurse-led peer support intervention. The postpartum depression and postpartum posttraumatic stress disorder was assessed by using Edinburgh postnatal depression scale (EPDS) and impact of event scale-revised (IES-R) before and after intervention. Results:Before intervention, the socre of EPDS and IES-R was no statistical difference between experimental group and control group ( P>0.05). After intervention, the scores of EPDS and IES-R were significantly decreased in the experiment group [(5.41 ± 0.49) pionts, (16.56 ± 1.36) pionts] compared to the control group [(16.56 ± 1.36) pionts, (19.01 ± 1.98) pionts], the difference was statistically significant ( P<0.05). Conclusion:Nurse-led peer support system can alliviate postpartum depression and posttraumatic stress disorder status and promote the psychological health of primipara.

{L-End}Objective To investigate the influencing factors of work-related musculoskeletal disorders (WMSDs) that affect neck-shoulder-back among manufacturing workers. {L-End}Methods A total of 8 250 front-line workers from 27 manufacturing enterprises in Henan Province and Hubei Province were selected as the research subjects using cluster sampling method. The Musculoskeletal Disorders Questionnaire was used to investigate the prevalence of neck-shoulder-back (include neck, shoulder, upper back, and lower back) WMSDs in the past year. The log-binomial model, principal component analysis (PCA) and multivariate logistic regression analysis were used to analyze the influencing factors of WMSDs in the neck-shoulder-back. {L-End}Results The prevalence of WMSDs was 77.2%. The prevalence of neck-shoulder-back WMSDs was 50.9%. The prevalence ratios of WMSDs were relatively higher among the neck, shoulder, and upper back (all P<0.05). The results of PCA improved logistic regression analysis showed that the influencing factors of neck-shoulder-back WMSDs were individual factors, biomechanical factors, psychosocial factors and environmental factors. In terms of individual factors, the risk of neck-shoulder-back WMSDs was higher in females than in males (P<0.05). With the increase of age, length of service, and education level, the risk of neck-shoulder-back WMSDs increased among manufacturing workers (all P<0.05). The risk of neck-shoulder-back WMSDs of workers in textile, clothing, shoes and hats manufacturing industry was relatively lower than that in the other nine industries (all P<0.05). In terms of the biomechanical factors, spending a lot of effort to operate tools/machines, sitting for a long time at work,bending greatly bending and turning at the same time, neck leaning forward or maintaining this posture for a long time, neck twisting or maintaining this posture for a long time and uncomfortable position resulting in difficulty exerting exertion were all risk factors of neck-shoulder-back WMSDs among manufacturing workers (all P<0.05) Bending slightly for a long time was a protective factor for neck-shoulder-back WMSDs among manufacturing workers (P<0.05). In terms of the psychosocial factors, doing the same work every day, self-determination in resting time between works staff shortage, and frequent overtime work were risk factors for neck-shoulder-back WMSDs among manufacturing workers (all P<0.05). Adequate resting time was a protective factor for neck-shoulder-back WMSDs among manufacturing workers (P<0.01). In terms of environmental factors, working under cold or fluctuating temperature, having nothings to lean on, and soles slipping or falling at work were all risk factors for neck-shoulder-back WMSDs among manufacturing workers (all P<0.05). {L-End}Conclusion Manufacturing workers are prone to suffer from neck-shoulder-back WMSDs. The influencing factors include individual factors, biomechanical factors (force load and static load), psychosocial factors and environmental factors.
