Objective:To explore the correlation between serum NLR and SII levels and postmenopausal osteoporotic vertebral compression fracture (OVCF) and to analyze the short-term prognostic value.Methods:A total of 132 patients with postmenopausal OVCF admitted to our hospital from Dec. 2018 to Dec. 2021 were selected as the study group, and 98 patients with postmenopausal osteoporosis but did not suffer from OVCF were selected as the control group. According to the recurrence of postmenopausal OVCF fractures, the ROC curves of NLR and SII were plotted, and their prognostic value for postmenopausal osteoporosis OVCF was analyzed.Results:NLR level was 2.96±0.41 and STI level was 39.41±23.45 in the control group. The level of NLR was 3.42±0.32 and SII was 431.77±31.14 in the research group ( P<0.05) . Multivariate Logistic regression analysis showed that lumbar bone density ( OR=0.030, 95%CI: 0.001-0.832, P=0.042) , NLR level ( OR=29.43, 95%CI: 9.840-103.6, P=0.001) and SII level ( OR=1.048, 95%CI: 1.034-1.066, P=0.001) were all risk factors affecting postmenopausal OVCF. NLR (3.77±0.22) and SII (441.32±29.68) in the recurrent fracture group were higher than NLR (3.27±0.22) and SII (426.87±30.57) in the non-recurrent fracture group, and the differences were statistically significant (all P<0.05) , multivariate Logistic regression analysis showed lumbar spine bone density ( OR=8.56×10 4, 95% CI: 3.884-2.992×10 10, P=0.045) , NLR level ( OR=1.243×10 -8, 95% CI: 2.911×10 -13-1.072×10 -5, P=0.001) and SII level ( OR=0.938, 95% CI: 0.885-0.976, P=0.008) were all influencing factors affecting the postoperative treatment effect of postmenopausal OVCF, and ROC results showed that both NLR (AUC=0.86, 95% CI: 0.77-0.94, P<0.001) and SII (AUC=0.76, 95% CI: 0.67-0.85, P<0.001) had good prognostic value for postmenopausal OVCF. Conclusion:NLR and SII are risk factors for OVCF in postmenopausal osteoporosis patients, and have good short-term prognostic value.
Résumé
Objective To evaluate and summarize the evidence related to targeted temperature management in brain injury patients with ICU for health care workers and decision makers.Methods We systematically searched from the guideline websites,domestic and foreign databases and association official websites to collect the literature including guidelines,expert consensuses,clinic decision-making,evidence summaries and systematic reviews,according to the 6s evidence model.The search time limit was from January 2012 to April,2023.Evidence was extracted after the quality evaluation of the literature was conducted by evidence-based researchers.Results A total of 19 articles were incorporated,including 6 guidelines,3 clinic decision-making,5 expert consensuses,4 systematic reviews and 1 evidence summary.Finally,25 pieces of best evidence were formed from 10 aspects,temperature range,starting time,body temperature monitoring,pipeline management,analgesia and sedation management,mechanical ventilation and oxygenation management,hemodynamic support,nutrition management,condition monitoring and prognosis evaluation.Conclusion The best evidence for management of targeted temperature in brain injury patients with ICU in this study is scientific and comprehensive,providing the evidence-based basis for medical staff to standardized management of targeted temperature in critically ill patients in clinical practice.

Objective:To explore the risk factors of unplanned readmission in patients with acute myocardial infarction, and to construct a risk prediction model.Methods:This study used cross-sectional survey method. A total of 270 acute myocardial infarction patients admitted from Tianjin Union Medical Cencer from March 2020 to March 2021 were evaluated in a cardiology department. We used the electronic medical record system to collect the patients′ data. Patients were divided into two groups according to the occurrence of readmission within 1 year or not. Logistic regression analysis was performed to identify risk factors and formulated prediction model.Results:Totally 81 patients (30%) were readmitted. Binary Logistic regression model showed that the independent influencing factors of unplanned readmission in acute myocardial infarction patients included smoking ( X1), hypertension ( X2), marital status ( X3), hospitalization days ( X4), percutaneous coronary intervention ( X5), and heart failure ( X6). Area under ROC curve was 0.840, the maximum value of the Youden index was 0.560, and the sensitivity was 85.2%, the specificity was 70.8%, and the cutoff value was 0.377. Prediction model expression of unplanned readmission risk in patients with acute myocardial infarction was Logit(p/1-p)=-4.012+1.172 X1+1.104 X2+0.992 X3+0.118 X4+1.191 X5+1.093 X6. Conclusions:The risk prediction model of unplanned readmission in patients with acute myocardial infarction established in this article was with a good predictive effect, and it could be used in early identification of those patients with high-risk in unplanned readmission. At the same time, combined with the risk factors of depression, targeted intervention measures can be formulated.
Résumé
Cognitive dysfunction,as a common symptom among patients with chronic fatigue syndrome (CFS) and patients with fibromyalgia(FM),impacts on life quality,occupation and study of these patients.However,the neural correlates to the cognitive impairment are unknown.Event related potentials,which reflect the information processing objectively and constantly,provide possibility for taking a insight into and estimating the dysfunction.By summarizing and analyzing studies in event related potentials about chronic fatigue syndrome,fibromyalgia,we found that CFS patients were characterized with prolonged latency of N200 and P300 accompanied by decreased P300 amplitude when they performed on Oddball paradigm,fibromyalgia patients were characterized with lower P300 amplitude when they concentrated on Oddball task,meanwhile,fibromyalgia patients also showed decreased P100/N100,P200,P300,LPC in emotional word decision task and somatic pictures decision task.It's suggests that the cognitive dysfunction in CFS is mainly caused by slowed speed of information identification and classification,whereas in FM it's dysregulation in attention control system results in the cognitive dysfunction.Limitations in current studies and prospects on researches about cognitive dysfunction in CFS for future were also discussed.

Objective To evaluate the efficiency and functional improvement of masseter-to-facial nerve transfer for patients who acquired a proximal iniury to the facial nerve and preliminary determine the influence factors for recovery.Methods From January,2015 to May,2016,the clinical data of 6 patients with facial paralysis underwent nerve anastomosis were analyzed retrospectively.These patients were required to come back to the hospital for a check every 3 months,in order to evaluate their facial nerve function.House-Brackmnann(H-B)grading was used to evaluate the pre-oerative,post-operative and follow-up status.The masseter-to-facial nerve anastomosis was performed in all the 6 patients.Results All patients were followed-up.The mean time of follow-up was 16 months (ranged from 6 to 23 months).Among 6 cases,the facial nerve function was improved in 5 cases,unchanged in 1 case.The postoperative H-B grades were Ⅱ in 3 cases,Ⅲ in 2 cases.The improvement of facial paralysis was most significant for orbicularis muscles,followed by the orbicularis oculi muscles,and the worst was the improvement of frontal muscles.Conclusion Masseter-to-facial nerve transfer anatomosis is a useful treatment for facial paralysis and can improve the facial function.

Objective To optimize the technological conditions of polysaccharide purification from compound Qianyu water decoction. Methods Water extraction and alcohol precipitation, resolution, Sevag method and dialysis method were used to purify polysaccharide.The purity of polysaccharide was measured with the phenol-sulfuric acid spectrophotometry.On the basis of single factor test, effects of redissolved solid-liquid ratio, number of protein removal, and dialytic time on polysaccharide purity of Qianyu were investigated by orthogonal test. Results The best conditions for purification of polysaccharide in Qianyu were as follows: liquid-solid ratio was 1:40(g/mL, W/V), remove protein for 10 times, and dialysis for 18 h.The content of polysaccharide could reach 69.04%, and the transfer rate was 51.84%. Conclusion The optimized purification process was simple and accurate.It can be used for polysaccharide purification in compound Qianyu water decoction.
