Cost-effectiveness Analysis of Long-effect versus Short-effect Granulocyte Stimulating Factor in the Prevention and Treatment of Bone Marrow Suppression Induced by Chemotherapy for Lung Malignancies / 中国药房

OBJECTIVE： To compare the cost-effectiveness of long-effect and short-effect granulocyte stimulating factor in prevention and treatment of bone marrow suppression induced by chemotherapy for lung malignancies， and to provide reference for rational drug use in the clinic. METHODS： A retrospective analysis was conducted for 132 cases who used granulocyte stimulating factor to prevent and treat bone marrow suppression induced by chemotherapy for lung malignancies in the Affiliated Tumor Hospital of Zhengzhou University during Jan. 2017 to Jun. 2018. Among them， 60 cases were treated with Recombinant human granulocyte stimulating factor injection （short-effect， group A）， and 72 cases were treated with Polyethylene glycol recombinant human granulocyte stimulating factor injection （long-effect， group B）. Clinical efficacies， the occurrence of bone marrow suppression and ADR were compared between 2 groups. Cost was calculated， and cost-effectiveness analysis was conducted. Sensitivity analysis was conducted by down-regulating 20％ drug price. RESULTS： The total response rates of group A and B were 71.7％ and 75.0％， without statistical significance （P＞0.05）. There was no statistical significance in the incidence and duration of bone marrow suppression or the incidence of ADR （P＞0.05）. Average treatment costs of the two groups were （335.91±180.34） and （1 982.75±603.15） yuan； the cost of group A was significantly lower than that of group B （P＜0.05）. The cost-effectiveness ratio of them were 4.69 and 26.44， while group A as a reference， incremental cost-effectiveness ratio of group B was 494.55. The sensitivity analysis results were in agreement with the cost-effectiveness analysis. CONCLUSIONS： The effectiveness of Recombinant human granulocyte stimulating factor injection is similar to that of Polyethylene glycol recombinant human granulocyte stimulating factor injection for the prevention and treatment of bone marrow suppression induced by chemotherapy for lung malignancies. But the cost-effectiveness ratio of the former is lower than that of the latter.

Incidence and risk factors of cognitive impairment 3 months after first-ever stroke: a cross-sectional study of 5 geographic areas of China / 华中科技大学学报（医学）（英德文版）

This study examined the incidence, neuropsychological characteristics and risk factors of cognitive impairment 3 months after stroke in China. Five regions that differed in geography and economy in China were selected. Patients from the hospitals located in the five regions were prescreened at admission, and the demographic data, vascular risk factors and clinical characteristics of stroke were obtained. A battery of cognitive-specific domain tests was performed in the patients who failed to pass cognitive screening 3 months post stroke. Patients were diagnosed as having post-stroke cognitive impairment (PSCI) or no cognitive impairment (NCI) based on the results of the neuropsychological tests. Univariate analysis was performed for suspect risk factors, and significant variables were entered in multivariable logistic regression analysis. Our results showed that a total of 633 patients were recruited 3 months after stroke; complete cognitive tests were performed in 577 of the stroke patients. The incidence of PSCI in these Chinese patients was 30.7%. There were 129 (22.4%) patients with visuospatial impairment, 67 (11.6%) with executive impairment, 60 (10.4%) with memory impairment and 18 (3.1%) with attention impairment. The risk factors associated with PSCI were older age (odds ratio [OR] 1.76, 95% confidence interval [CI] 1.20-2.58), low education level (OR 2.45, 95% CI 1.65-3.64), depressive symptom (OR 1.69, 95% CI 1.09-2.61), obesity (OR 2.57, 95% CI 1.41-4.71), stroke severity 3 months post stroke (OR 1.62, 95%CI 1.10-2.37) and cortex lesion (OR 1.55, 95% CI 1.04-2.31). It was concluded that PSCI occurs commonly 3 months after first-ever stroke in Chinese patients. Visuospatial ability may be the most frequently impaired cognitive domain for the patients with stroke. The critical risk factors of PSCI are older age, low education level, depressive symptom, obesity, stroke severity 3 months post stroke and cortex lesion.

Relationship between rapid-eye-movement sleep behavior disorder and synucleinopathies / 中华神经科杂志

Objective To investigate the incidence rate, onset time and electrophysiological characteristics of rapid eye movement sleep behavior disorder (RBD) and the relationship between RBD and synucleinopathies as well as the electrophysiological diagnostic criteria of RBD in Parkinson' s disease (PD) and multiple system atrophy (MSA). Methods Sleep survey and night video-polysomnography (NPSG)were used to study sleep disturbance of PD and MSA. (1) Subjective sleep assessments: All subjects,including 66 PD patients, 65 age and sex matched healthy controls and 30 MSA patients, completed the sleep questionnaires, and the RBD incidence rate and onset time were got. (2) Objective sleep assessments: 8 PD patients, 13 MSA patients, and 15 age and sex matched healthy controls underwent video-NPSG recording on two consecutive nights. Sleep architect were analyzed. The NPSG characteristics of RBD accompany with PD and MSA were analyzed, and the electrophysiological diagnostic varameters of it were determined. Results Patients with PD or MSA had a higher prevalence of RBD. RBD was found in 59. 1% (39/66) PD patients and 86. 6% (26/30) MSA patients, among those, 46. 2% ( 18/39 ) and 84.6% (22/26) had the waking symptoms of MSA and PD. The main NPSG characteristics of RBD of PD or MSA were chin REM without atonia (RWA) and increased movement. Conclusions The relatively higher RBD prevalence in MSA and PD patients indicates that RBD has close relationship with PD and MSA.Part of patients with RBD preceding neurology disease indicates that RBD may be the early marker of PD and MSA. The main NPSG characteristics of RBD accompany with PD and MSA are chin RWA and the motor manifestations. RWA and phasic EMG activity density are supposed to be the NPSG diagnostic parameters.

The application of Montreal cognitive assessment in urban Chinese residents of Beijing / 中华内科杂志

Objective To study the distribution of Montreal cognitive assessment(MoCA)scores in terms of age and educational level in Chinese residents aged 50 years and over and to offer a benchmark for a cutoff score.Methods A total of 281 residents aged 50 years or older was drawn randomly in the urban areas of Beijing,including 215 healthy elderly controls(NC)and 66 patients meeting the clinical criteria of mild cognitive impairment(MCI).The final scores for MoCA were given in the form of mean percentage distributions specific for age,sex and educational level so as to compare the validity of MMSE mini-mental state examination and MoCA in detecting MCI.By a fitting muhiple regression model the influenee of the factors on MMSE and MoCA was assessed.Results Using a cutoff score of 26.MMSE had a sensitivity of 24.2%to detect MCI.whereas MoCA detected 92.4%of the MCI subiects.We found a bivariate correlation between MoCA scores and both the factors of age and educational level(P＜0.001).Conclusions MoCA iS a brief cognitive screening tool with high sensitivity and specificity for detecting MCI as currently conceptualized in patients performing normally on MMSE.Our adiustment in the cutoff scores would improve the detection of MCI and Alzheimer'S disease by reducing the number of false negatives.MoCA scores should be used to identify current cognitive difficulties but not to make formal diagnoses.
