Objective:To investigate the predictive value of systemic inflammatory response index (SIRI) for early neurological deterioration (END) and clinical outcome in patients with branch atherosclerotic disease (BAD).Methods:Consecutive patients with BAD admitted to the Department of Neurology, Jiangyin People’s Hospital Affiliated to Southeast University from September 2021 to September 2022 were retrospectively included. The clinical data were collected and SIRI was calculated. The calculation method of SIRI was neutrophil count × monocyte count/lymphocyte count. END was defined as an increase of ≥2 in the total score of the National Institutes of Health Stroke Scale (NIHSS) or an increase of ≥1 in the motor function score within 1 week of onset. The modified Rankin Scale was used for outcome evaluation at 3 months after onset, with a score >2 were defined as poor outcome. Multivariate logistic regression analysis was used to determine the independent correlation between SIRI and END, as well as poor outcome. Receiver operating characteristic (ROC) curve was used to evaluate the predictive value of SIRI for poor outcome. Results:A total of 125 patients with BAD were included, of which 62 (49.6%) had END and 32 (25.6%) had poor outcome. The multivariate logistic regression analysis showed that intravenous thrombolysis (odds ratio [ OR] 1.083, 95% confidence interval [ CI] 1.082-1.240; P=0.043) and high SIRI ( OR 1.465, 95% CI 1.150-3.676; P=0.028) were independent risk factors for END in patients with BAD; END ( OR 1.130, 95% CI 1.032-1.384; P=0.006), high baseline NIHSS score ( OR 1.571, 95% CI 1.184-2.101; P=0.003) and high SIRI ( OR 2.062, 95% CI 1.152-3.672; P=0.01) were independent risk factors for poor outcome in patients with BAD. ROC curve analysis showed that the area under the curves for SIRI, baseline NIHSS score, and the both combined prediction of poor outcome were 0.66 (95% CI 0.54-0.78), 0.70 (95% CI 0.58-0.81), and 0.83 (95% CI 0.74-0.93), respectively. Conclusions:High SIRI is an independent risk factor for END and poor outcome in patients with BAD. The SIRI and baseline NIHSS scores have certain predictive value for poor outcome in patients with BAD, and their combined diagnostic value is higher.

Objective:To explore any effect of using extracorporeal shockwave therapy (ESWT) on the gastrocnemius muscle or the myotendinous junction on spasticity and the walking ability of stroke survivors.Methods:A total of 84 stroke survivors were randomly divided into a control group, a muscle belly group, and a myotendinous junction group, each of 28. In addition to conventional rehabilitation, the muscle belly and myotendinous junction groups received ESWT applied to the belly of the gastrocnemius muscle or the myotendinous junction. Before as well as one, two and three weeks after the treatment, all were evaluated using the Modified Ashworth Scale (MAS), passive range of motion (PROM), a visual analogue scale (VAS) for pain rating, and 10m maximum walking speed (10m MWS). Stride frequency and length were also measured and compared among the 3 groups.Results:After three weeks of ESWT treatment the average MAS, PROM and VAS scores of the belly and the junction group were significantly improved compared to before the treatment. The average MAS, PROM and VAS scores of the belly group and the average MAS score of the junction group were then significantly superior to the control group′s averages, and the average VAS score of the belly group was significantly better than that of the junction group. After one and two weeks of treatment, the average 10MWSs of the belly and junction groups were significantly better than the control group′s average, and after 3 weeks the belly group′s average speed was significantly better than the junction group′s. The stride frequency of the belly group had improved significantly compared with the control group after 2 weeks, and after 3 weeks both experimental groups had significantly better frequency than the control group. The average stride length of both the belly and junction groups was significantly better than the control group′s average throughout the testing.Conclusion:ESWT applied to the belly of the gastrocnemius muscle or the myotendinous junction can relieve muscle spasticity and pain and improve walking ability. Applying ESWT to the muscle belly is superior to on the myotendinous junction in terms of therapeutic efficacy.

Objective:To detect the changes in mental arithmetic competence and the related influencing factors in patients with early Parkinson's disease(PD)by using mental arithmetic task behavioral experiment.Methods:Thirty-one patients with early PD and 40 healthy controls were enrolled in this study.The cognitive functions were tested by mini-mental state examination(MMSE)and Montreal cognitive assessment(MoCA). The differences of mental arithmetic competence between the two groups were measured by behavioral experiment.Results:There was no significant difference in correct rate, reaction time and post-corrected reaction time while performing baseline tasks and easy mental arithmetic tasks between the two groups( P>0.05). The reaction time had no significant difference between the two groups after adjusting some confounding factors( P>0.05). However, the correct rate while performing difficult mental arithmetic tasks was significantly lower( t=-2.232, P=0.029)and the reaction time was significantly longer( t=2.149, P=0.035)in PD group than in the controls, and the significant difference in reaction time persisted even after adjusting some confounding factors( t=3.139, P=0.003). In PD group, the correct rate of difficult mental arithmetic tasks was positively associated with MoCA scores( r=0.561, P=0.004), and negatively associated with age( r=-0.532, P=0.008). The reaction time and post-corrected reaction time while performing difficult metal arithmetic task were negatively associated with MoCA scores( r=-0.525, P=0.01; r=-0.554, P=0.005)and positively associated with age( r=0.485, P=0.037; r=0.514, P=0.012)in PD group. Conclusions:The difficult mental arithmetic competence is impaired in early PD patients, which is statistically significantly correlated with cognitive function and age.

Amniotic fluid embolism (AFE) is a clinical syndrome caused by amniotic fluid suddenly going into the maternal blood circulation in the process of delivery, the incidence is extremely low, however, its mortality is relatively high; since its clinical manifestations lack specificities, misdiagnosis or overlook of its presence often occurs. In this article, 1 case of delayed amniotic fluid embolism complicated with pituitary crisis leading to difficulty in weaning mechanical ventilation was reported in order to improve the understanding of AFE.
