RESUMEN
BACKGROUND: Coronary bifurcation remains one of the most challenging lesion subsets in interventinal cardiology. Provisional stenting (PS) is the dominate technique for bifurcation lesions, but the key problem is the deterioration of side branch. Balloon-stent kissing technique (BSKT) as a new systematic approach which is based on modified jailed balloon technique is applied to improve the procedure success. In our center, we proposed a modified balloon-stent kissing technique(M-BSKT), which routine usage of proximal optimizing technique (POT) after rewiring was added as an optimization step to BSKT. Thus, whether M-BSKT for addressing simple true coronary bifurcation lesions can provide more benefits in intra-operation effect and long term outcomes is still unknown. METHODS: A cohort of 120 consecutive patients underwent Percutaneous Coronary Intervention (PCI) with simple true coronary bifurcation lesions satisfied the criteria were included in this retrospective, single-center registry. To assemble a cohort with similar baseline characteristics, a 1:1 propensity-matched score was used. The primary outcomes were the rate of device and procedural success, the situation of side branch (SB) after main vessel (MV) inflation and the complications during intra-operative. The secondary outcomes were the clinical prognosis at 12 months such as rehospitalization for unstable angina and MACEs. RESULTS: Before propensity matching, there were no significant differences in primary and secondary outcomes between two groups. After propensity-matched was used, 68 patients with similar propensity scores were included. At immediate procedural, M-BSKT was associated with a lower risk of SB deterioration and the application of final kissing balloon inflation (FKBI)[P = 0.036]. For ACS patients, besides the significant differences of immediate SB deterioration [P = 0.014] and FKBI application [P = 0.033], the incidence of TIMI flow< 3 in the PS was statistically significant higher than M-BSKT [P= 0.042]. The prognosis at 12 months such as rehospitalization for unstable angina and MACEs were similar for two groups [P = 0.613]. CONCLUSION: These observations prove that the M-BSKT enables side branch to be better protected in simple true bifurcation lesions, by a narrow margin. It may improve the angiographic outcomes about side branch deterioration and final kissing balloon performing compared with PS, especially in ACS patients. However, long-term clinical outcomes did not differ between patients treated for M-BSKT and PS at 12 months.

Neuropsychiatric symptoms are common in patients with Parkinson's disease (PD) and they are likely to outweigh the motor symptoms and become a major factor affecting the quality of life of PD patients. However, the studies focusing on the non-motor symptoms in Chinese PD patients from different ethnicity are scarce. The aim of this retrospective study was to investigate neuropsychiatric symptoms and cognitive impairment in Chinese PD patients from Han and Hui populations from central China. Seventy-two Han Chinese PD patients (Han PD group) and 71 age-and sex-matched Hui Chinese PD patients (Hui PD group) were enrolled from Zhongnan Hospital of Wuhan University between Sept. 2011 and Aug. 2014 in the study. The neuropsychiatric symptoms and cognitive impairment were assessed using Neuropsychiatric Inventory (NPI) and Mini Mental State Examination (MMSE). We found that the proportion of depression, anxiety, apathy, irritability, euphoria and night time behavior disturbances were higher in the Han PD group than in the Hui PD group (P<0.05 or P<0.01). But the proportion of delusion, hallucination, agitation, disinhibition, aberrant motor behavior and change in appetite were not significantly different between the Han PD group and the Hui PD group (P>0.05). The total mean scores of the MMSE from patients in the Han PD group were similar to those in the Hui PD group (P>0.05). However, the subscale scores of recall domain and language domain in the Han PD group were significantly different from those in the Hui PD group (P<0.05). No significant difference was noted in the orientation, memory and calculation domains between the two PD groups (P>0.05). This study first showed the recall domain and language domain were different between the Han PD patients and the Hui PD patients. Depression, anxiety, apathy, irritability, euphoria and night time behavior disturbances were less presented in the Hui PD patients. All these differences may be related to the different ethnicity, which would be helpful for clinical physicians to recognize the different non-motor symptoms in Chinese PD patients with different ethnicity.

OBJECTIVE: Progressive cerebral infarctions increase mortality and functional disability through mechanisms which have yet to be completely understood. The goal of this study was to explore the dynamic changes of serum C-reactive protein (CRP), fibrinogen (FIB) and D-dimer (D-D) in order to better characterize progressive cerebral infarction. METHODS: The amount of serum CRP, FIB and D-D was measured in 82 patients with progressive cerebral infarction by taking samples from the internal carotid artery (progressive group), and in 186 patients with non-progressive cerebral infarction (non-progressive group) by using an automatic biochemical analyzer during the next day (day 1), day 3, day 7, and day 14 after being admitted to hospital. Carotid vascular ultrasound and neurological deficit score (National Institutes of Health Stroke Scale, NIHSS) were also recorded. RESULTS: Carotid stenosis ratio was significantly higher in the progressive group than in the non-progressive group (P < 0.01) on admission. In the progressive group, CRP increased significantly on day 3, followed by a decline on day 7 and day 14, but was significantly higher than those in the non-progressive group (P < 0.01). The levels of FIB and D-D increased in the progressive group more than those in the non-progressive group on day 3, day 7, and day 14 (P < 0.01). The progressive group patients' NIHSS score gradually increased after admission, which was opposite to the non-progressive group patients whom followed a downward trend. The difference between these two groups was significant (P < 0.01). CONCLUSION: Observing changes of CRP, FIB and D-D may contribute to early identification and timely treatment of progressing ischemic strokes.
RESUMEN
Stroke research and rehabilitation have traditionally focused on the physical and functional impact of a stroke. Less attention has been given to the psychosocial factors associated with this chronic condition. By the few studies that have specifically focused on psychosocial factors in the context of stroke, poststroke depression is demonstrated to significantly influence stroke outcomes. Associations of stroke with psychological symptoms other than depression have rarely been evaluated. This study was aimed to investigate the changes of psychological stress, social support and medication adherence in patients with ischemic stroke in the mainland of China. In this study, 90 patients with hemiplegia one year after first-ever middle cerebral artery infarction (stroke group) in the Zhongnan Hospital of Wuhan University from June 2008 to June 2011 were recruited for interview. Ninety age- and sex-matched normal volunteers (control group) were also examined at the same period. The psychological distress was assessed by the Symptom Checklist 90 (SCL-90), the social support by the Social Support Rating Scale (SSRS), and medication adherence by Morisky's self-reported inventory, respectively. Group differences were analyzed using unpaired-t test and chi-squared test. The results showed that total mean scores of the SCL-90 in the stroke group were higher than those in the control group (P<0.01). Except two dimensions, paranoid ideation and psychoticism, mean scores of the rest dimensions (including somatization, obsession-compulsion, interpersonal sensitivity, depression, anxiety, hostility, and phobic anxiety) of SCL-90 were significantly higher in the stroke group than those in the control group (P<0.05, or P<0.01). The objective support, subjective support, support availability and total social support scores in the stroke group were significantly higher than those in the control group (P<0.05, or P<0.01). Those in the "SCL-90 total scores >150 group" were significantly higher than in the "SCL-90 total scores <100 group" and the "SCL-90 total scores between 100 to 150 group" (P<0.05, or P<0.01). Those in the "SCL-90 total scores between 100 to 150 group" were significantly higher than in the "SCL-90 total scores <100 group" (P<0.05). In 90 patients with ischemic stroke, 26 (28.89%) patients obtained high medication adherence, 47 (52.22%) patients medium medication adherence, and 17 (18.89%) patients low medication adherence, respectively. Among these stroke patients, there were 17 (50.00%) patients with high medication adherence in the "SCL-90 total scores >150 group", 28 (75.67%) patients with medium medication adherence in the "SCL-90 total scores between 100 to 150 group", and 12 (61.16%) patients with low medication adherence in the "SCL-90 total scores <100 group", respectively. There was significant difference in the medication adherence rate among the different SCL-90 scores groups in these stroke patients (P<0.05 or P<0.01). It was led to conclude that ischemic stroke patients one year after hemiplegia have psychological distress, low level of social support and poor medication adherence in the mainland of China. Therefore, it is necessary to mobilize the government, medical institutions and various social support groups to offer psychological interventions to relieve the stress of patients with ischemic stroke, and improve their medication adherence.

BACKGROUND: Neuropsychiatric deficits can induce marked disability in patients with dementia and increase caregiver distress. Several studies have found that neuropsychiatric symptoms are common both in patients with Alzheimer's disease (AD) and patients with vascular dementia (VaD). However, there are few studies of the neuropsychiatric disturbances in large clinical samples of patients with mixed (cortical - subcortical) VaD from mainland China. This study aimed to investigate the neuropsychiatric symptoms in VaD patients in mainland China. METHODS: Eighty patients with mixed VaD for over 6 months duration, and their caregivers (VaD group), were recruited for interview in Zhongnan Hospital of Wuhan University, from June 2010 to June 2012. Eighty age- and sex-matched normal volunteers (control group) were interviewed at the same time. The Mini Mental State Examination (MMSE) and the Neuropsychiatric Inventory (NPI) were administered to the VaD patients, their caregivers, and normal volunteers. Group differences were analyzed using the unpaired t-test. RESULTS: The total mean scores of the NPI in the VaD group were higher than in the control group (P < 0.01). The subscale scores of NPI, including delusions, hallucinations, depression, apathy, irritability, agitation, aberrant motor behavior, and change in appetite were significantly higher in the VaD group than in the control group (P < 0.05-0.01). Compared with the mild VaD subgroup, the NPI subscale scores of apathy, irritability and total scores were significantly higher in the moderate VaD subgroup (P < 0.05-0.01); the NPI subscale scores of anxiety, apathy, irritability, and total scores were significantly higher in the severe VaD subgroup (P < 0.01). Compared with the moderate VaD subgroup, the NPI subscale scores of anxiety and apathy were significantly higher in the severe VaD subgroup (P < 0.05-0.01). CONCLUSIONS: Neuropsychiatric symptoms, such as hallucination, anxiety, apathy, irritability and aberrant action behavior, are common in patients with mixed VaD from mainland China; anxiety and apathy were more pronounced in the subgroup of severe VaD patients.
RESUMEN
Sulfur mustard (SM) is believed to be a major threat to civilian populations because of the persistent asymmetric threat by nonstate actors, such as terrorist groups, the ease of synthesis and handling, and the risk of theft from stockpiles. The purpose of this study was to establish mechanisms of acute tracheal injury in rats induced by SM using histopathologic, immunohistochemical, and biochemical parameters. Male rats (Sprague-Dawley) were anesthetized, intratracheally intubated, and exposed to 2 mg/kg of SM. Animals were euthanized 6-, 24-, 48-, and 72-hour postexposure, and intracavitary blood samples from the heart and tracheal tissues were collected. Exposure of rats to SM resulted in rapid tracheal injury, including tracheal epithelial cell shedding, focal ulceration, and abundant lymphocyte invasion of the submucosa. There was also evidence of a large number of apoptotic cells in the epithelium and submucosa, the serum levels of tumor necrosis factor α, interleukin 1ß (IL) 1ß, IL-6, and γ-glutamyl transferase peaked at 24 hours, and the serum levels of lactate dehydrogenase, glutathione peroxidase, and thiobarbituric acid reactive substance peaked at 6 hours. The SM exposure also resulted in a loss of the cellular membrane, leakage of cytoplasm, fuzzy mitochondrial cristae, medullary changes in ciliated and goblet cells, and the nuclear chromatin appeared marginated in basal cells and fibroblasts. The results in the propylene glycol group were the same as the control group. These data demonstrated the histologic changes, inflammatory reactions, apoptosis, oxidative stress, and DNA damage following SM (2 mg/kg)-induced acute tracheal injury; the severity of changes was time dependent.
