ABSTRACT

Objective:To investigate the relationship between cognitive function and brain event-related potential in patients with lacunar cerebral infarction.Methods:A total of 464 patients with lacunar cerebral infarction admitted to the Department of Neurology, Kailuan General Hospital from 2014 to 2019 were prospectively selected as observation subjects (case group). According to mini-mental state examination (MMSE) score, the patients in the case group were divided into 352 cases of lacunar cerebral infarction with normal cognition and 112 cases of mild cognitive impairment. At the same time, 100 healthy volunteers were selected as the control group. All subjects were assessed by simple intelligent mental state, Zung self-rating anxiety scale, Zung self-rating depression scale and brain event-related potential P3a and P3b. The measurement data of normal distribution adopts one-way ANOVA, the measurement data of non normal distribution adopts Kruskal Wallis H test, and the counting data adopts χ2. Multivariate statistical analysis was performed by unconditional Logistics (stepwise method). Results:The proportions of smokers in control group, lacunar cerebral infarction cognitive normal group and lacunar cerebral infarction mild cognitive impairment group were 20.00% (20/100), 38.07% (134/352) and 46.42% (52/112), respectively.

Conclusion:The peak latency and amplitude of endogenous psychological cognitive potentials N2, P3b and P3a of event-related potentials P3b and P3a in patients with lacunar cerebral infarction were prolonged and decreased. At the same time, with the occurrence of clinical cognitive impairment, the peak latency and amplitude of these cognitive potentials were further prolonged and decreased more significantly. Alcohol consumption, P3b peak latency and PZ lead of visual P3b wave group, and FZ lead of N1 wave of visual P3a wave group were the influencing factors of simple intelligent mental state.

ABSTRACT

Objective:To analyze the relationship between homology of Kleber pathogen pneumoniae (KP) in patients with neurocritical infections and the Genomics.Method:Five non-multidrug resistant pathogen KP were identified in 2015 to 2018, including the same cloning strain of P90 and P91, the same popular cloning system of P66,P90 and P91, and there is no homology between P20,P39 and other strains, which makes a second generation full genome sequencing. A variety of bioinformatics software were used for genomic analysis to understand the basic genomic information, chromosomal and plasmid distribution, single nucleotide polymorphism (SNP) differences and gene family clustering characteristics, meanwhile with the National Center for Biotechnology Information (NCBI) website registered 18 KP strains (2013--2016) to analyze the evolutionary affinity between strains.Results:The total genome sizes of P20, P39, P66, P90 and P91 were 5 469 543 bp, 5 480 332 bp, 5 768 352 bp, 5 745 666 bp, 5 722 999 bp. The GC contents were 57.07% (1 559 929+1 561 432)/5 469 543, 57.27% (1 566 970+1 571 424)/5 480 322, 56.96% (1 640 438+1 645 432)/5 768 352, 56.88% (1 634 285+1 634 038)/5 745 666, and 56.95% (1 627 360+1 631 781)/5 722 999, respectively. Compared with P20 reference strains, the total number of SNP in P39, P66, P90 and P91 were 32 682, 34 226, 34 292, 34 375, and the total mutation rates of gene coding region sequences were87.18% (28 491/32 682), 86.71% (29 679/34 226), 85.26% (29 238/34 292), 86.22% (29 638/34 375), respectively. Nonsynonymous mutations accounted for some advantages, and the rates were 44.57% (14 566/32 682), 44.01% (15 063/34 226), 48.01% (16 465/34 292), 48.75% (16 758/34 375), and synonymous mutations were 42.61% (13 925/32 682), 42.70% (14 616/34 226), 37.25% (12 773/34 292), 37.47% (12 880/34 375), respectively. P90 and P91 have 6 specific gene families, and P66 has 4 specific gene families. The same popular clone lines P66, P90 and P99 are on the same evolutionary branch of the phylogenetic tree. The same clone P90 and P99 are on the same subbranch. P20 and P39 without homology are on different evolutionary branches respectively. P20, P39, P66, P90 and P91 on the evolutionary branches of phylogenetic tree are closely related to the evolutionary grade of strain KP52-145 from France and strain ED23 from Taiwan, China submitted on NCBI website.Conclusion:Klebsiella pneumoniae in patients with neurocritical infection has the same clone, and the number of unique gene families among strains is the same. There are small differences in the number of unique gene families and the total number of SNPs among the same epidemic clone lines, and they are characteristic of the same evolutionary branch of the phylogenetic tree. The number of unique gene families and the total number of SNPs of non homologous strains are quite different, and they are in different evolutionary branches of the phylogenetic tree.

ABSTRACT

Objective:To observe the related factors of depression in patients with lacunar cerebral infarction with mild cognitive impairment.Methods:From 2016 to 2019, 114 patients with mild cognitive impairment of lacunar cerebral infarction in Kailuan General Hospital were selected as the research objects.MRI brain scan was completed within 72 hours after admission, and Zung′s self rating Depression Scale (SDS) was used to evaluate emotion within 1 week.According to the results of SDS, 69 patients with mild cognitive impairment and no depression of lacunar infarction were selected as the control group, and 45 patients with mild cognitive impairment and mild depression of lacunar infarction were selected as the case group.The general clinical data, the proportion of patients with lacunar infarction in different brain regions and cognitive function of the two groups were observed.Logistic regression method was used to analyze the risk factors of depression in patients with mild cognitive impairment of lacunar infarction, and the characteristics of clinical somatization symptoms were observed.Results:(1)There were 53 males (76.81%, 53/69) and 16 females (23.19%, 16/69) in the control group, 29 males (64.44%, 29/45) and 16 females (35.55%, 16/45) in the case group, and the difference between the two groups was statistically significant ( P=0.049). Hyperhomocysteinemia in the control group and the case group was 31.88% (22/69) and 53.33%(24/45), respectively, with statistically significant differences between the two groups ( P=0.003). (2) The incidence rates of lacunar infarction in basal ganglia and oval center was 80% (36/45) and 71.11% (32/45) in case group respectively, and 59.42% (41/69) and 18.84% (13/69) in control group respectively.The difference between two groups was statistically significant ( P values were 0.001 and <0.001), and there was no significant difference in infarct size in other regions ( P>0.05). (3) The rate of impaired attention and computing power in the case group was 88.89%(40/45), which was higher than that in the control group 78.26%(54/69), and the difference was statistically significant ( P=0.036). (4) Multivariate Logistic regression analysis showed that hyperhomocysteemia ( OR=2.659, 95% CI 1.041-6.793, P<0.05) and central oval infarction ( OR=10.332, 95% CI 4.069-26.235, P<0.01) were independent risk factors for mild cognitive dysfunction and depression in lacunar cerebral infarction.(5) The proportion of insomnia and tears with somatization symptoms in the case group was 35.56%(16/45) and 37.77%(17/45), respectively, which were higher than that in the control group 8.70%(6/69) and 2.90%(2/69), respectively, with statistically significant differences (all P<0.001). Conclusion:Hyperhomocysteinemia and hemioval central cerebral infarction are independent risk factors for depression in patients with lacunar cerebral infarction with mild cognitive dysfunction, accompanied by somatization symptoms of insomnia and tearing.

ABSTRACT

Objective:To explore the protective effects of exosomes derived from bone marrow mesenchymal stem cells(BMSC)on ischemia-reperfusion injury(IRI)in mice.Methods:A total of 30 C57BL/6 mice were randomly grouped into 6 groups of control, Norm-BMSC-exo, Hypo-BMSC-exo, IRI, Norm-BMSC-exo+ IRI and Hypo-BMSC-exo+ IRI.The model for IRI(25 min)was constructed.The serum levels of creatinine(Cr)and blood urea nitrogen(BUN)and histomorphology were examined at 24 h post-reperfusion.The levels of tumor necrosis factor-alpha (TNF-α), interleukin-1β(IL-1β)monocyte chemoattractant protein-1(MCP-1)and interleukin-10 (IL-10)were measured.The survival rate was observed for 7 days post-IRI.We also detected macrophage polarization glycolysis and oxidative phosphorylation(OXPHOS).Results:Compared with IRI group, Norm-BMSC-exo+ IRI group showed low levels of creatinine(Cr)and blood urea nitrogen(BUN)and mild pathological injury.The protective effects were enhanced in Hypo-BMSC-exo+ IRI group.BMSC-exo pretreatment could significantly improve the survival rate of mice post-IRI.Reverse transcription-polymerase chain reaction(RT-PCR)revealed that BMSC-exo significantly lowered the levels of TNF-α, IL-1β, MCP-1 and elevated the level of IL-10.BMSC exosomes polarized macrophage toward an M2 phenotype.And Hypo-exo could reprogramme macrophages to undergo a metabolic switch toward OXPHOS and away from glycolysis.Conclusions:Hypo-BMSC-exo could improve kidney injury via inducing M2 polarization in macrophages through promoting OXPHOS and suppressing glycolysis.

ABSTRACT

Objective:To explorer the optimal method of detecting donor kidney carrier carbapenem-resistant Klebsiella pneumoniae (CRKP).Methods:Clinical data were retrospectively analyzed for 1120 donation-after-circulatory-death (DCD) kidneys and bacterial detection of kidney perfusion fluid was performed from January 2015 to January 2019. A total of 1120 kidney perfusion fluid samples were collected with sterile tubes and submitted for culturing. And 451 specimens were delivered in sterile tubes and blood culture bottles simultaneously And 729 specimens assayed for carbapenemase genes with GeneXpert.Results:Among 1120 kidneys, CRKP was confirmed in 21 grafts with an infection rate of 1.87 %. The detection of carbapenemase genes with Genexpert showed that KPC was positive for 9/16 CRKP positive grafts. Sensitivity, specificity, false-positive rate, false-negative rate and ROC-AUC were calculated at 56.3 %, 100 %, 0, 43.7 % and 0.781 respectively. And 11 specimens delivered with sterile tube were culture positive for CRKP. Sensitivity, specificity, false-positive rate, false-negative rate and ROC-AUC were calculated at 52.3 %, 100 %, 0, 47.6 % and 0.762 respectively. Among 451 perfusion fluid samples collected with anaerobic blood culture bottle, 15 samples had a positive culture for CRKP. Sensitivity, specificity, false-positive rate, false-negative rate and ROC-AUC were calculated at 100 %, 100 %, 0, 0 and 1 respectively. In terms to anaerobic blood culture bottle, sensitivity, specificity, false-positive rate, false-negative rate and ROC-AUC were calculated at 60 %, 100 %, 0 , 40 % and 0.80 respectively.Conclusions:Genexpert assay is suitable for rapid and convenient detection of carbapenemase genes using kidney perfusion fluid. Culturing perfusion fluid samples collected with anaerobic blood culture bottle is clinically valuable diagnostic tool of CRKP. A combination of both methods is worthy of clinical promotion and application diagnosis of donor kidney derived CRKP in terms of greater accuracy and timeliness.

ABSTRACT

Objective:To observe the changes of somatosensory evoked potential (SEP) in the upper limbs of patients with acute middle cerebral artery (MCA) cerebral infarction, and to explore its relationship with neurological impairment.Methods:From January 2015 to December 2016, 62 patients with 38 cases of male and 24 women of cerebral infarction who were treated in the department of neurology, Kailuan General Hospital were selected for a retrospectively prospective cohort study, including 38 males and 24 females.aged (66.7 ± 10.9) years old and ranging from 33.0 to 85.0 years old.According to the side of cerebral infarction, 37 cases were divided into left MCA group and 25 cases into right MCA group.During the 48 hours of admission, the electromyography evoked potential meter was used to detect the upper limb SEP, and the peak latency, amplitude and electrical activity waveform of the cerebral cortex potentials N20, P25 and N35 were recorded.Results:The results of SEP in the contralateral limbs of the left and right MCA cerebral infarction group were as follows: 1 case (2.70%) and 5 cases (20.00%) of normal median nerve; 36 cases (97.30%) and 20 cases (80.00%) of abnormality.The ratio of median nerve abnormalities in the group was statistically significant (χ 2=12.577, P<0.001). The ulnar nerve was normal in 3 cases (8.11%), 4 cases (16.00%); 34 cases (91.89%) and 21 cases (84.00%) were abnormal.There was no statistically significant difference between the two groups (χ 2=2.320, P=0.128). The peak latency and/or amplitude of each peak decreased in 34 groups (60.71%) and 33 cases (60.00%) of the ulnar nerve; the waveform of electrical activity disappeared, 22 cases (39.29%) of median nerve and 22 cases of ulnar nerve (40.00%). The peak latency and/or amplitude decreased, the electrical activity waveform disappeared, and the median nerve and ulnar nerve were compared, and the difference was not statistically significant (χ 2=0.021, P=0.885). The National Institue of Health Storke Scale(NIHSS) scores of left and right MCA cerebral infarction group were 34 (91.89%) and 19 (76.00%) respectively.Among them, the disappearance of electrical activity waveform were 18 cases (52.94%) and 4 cases (21.05%)of median nerve; 18 cases (52.94%) and 4 cases (21.05%) of ulnar nerve.The SEP electrical activity waveform disappeared in patients with moderate or higher neurological impairment, and the median nerve and ulnar nerve were statistically significant (χ 2=20.613, 20.613, all P<0.001). Conclusion:The median nerve and ulnar nerve SEP of the contralateral upper limb, which is dominated by the acute middle cerebral artery cerebral infarction, were abnormally changed.The main manifestations were that the latency of each peak of N20, P25 and N35 was prolonged and/or the amplitude was significantly decreased, and the waveform of SEP electrical activity disappeared.In addition, the disappearance of SEP wave activities only occurred in moderate and above neurological damage

ABSTRACT

Objective: To examine the relationship of clinicopathological features and treatment strategies with the prognosis of patients with initially diagnosed stageⅣbreast cancer bone metastasis (IDBCBM). Methods: Clinical data from 74 patients with IDBCBM who were treated at Tianjin Medical University Cancer Institute and Hospital between March 2007 and November 2016 were analyzed retrospectively. A univariate analysis of prognosis was conducted using a Log-rank test, and the subsequent multivariate analysis was conducted using a Cox regression model. Results: The median age of the patients was 53.3 years. The median total survival duration (overall survival, OS) was 34.3 months, and the 3-and 5-year survival rates were 37.8% and 12.2%, respectively. Patients for whom the first distant metastasis was bone metastasis only had a better prognosis, with a median survival duration of 41.7 months and overall 3-and 5-year survival rates of 54.5% and 20.4%, respectively. In the univariate analysis, molecular subtype, hormonal receptor status, HER-2 expression levels, nodal status, Ki-67 index, number of bone metastases (NBM), initial mode of metastasis, mode of therapy, and locoregional treatment showed an association with prognosis. Further, multivariate analysis demonstrated that Ki-67 index, NBM, mode of therapy, and initial mode of metastasis were independent factors affecting OS (P<0.05). Conclusions: A high Ki-67 index, single mode therapy, the presence of multiple bone metastases, and accompanying visceral metastasis were associated with a poor prognosis. However, it remains unclear whether locoregional treatment, including surgery and radiotherapy treatment of the primary tumor, is beneficial.

ABSTRACT

Objective To summarize the radiological features of follicular dendritic cell tumor of spleen (FDCS).Methods The clinical, radiological and pathological data of 8 patients from November 2011 to November 2017 in 5 hospitals with FDCS confirmed by pathology were retrospectively analyzed. All patients underwent CT examinations including plan and enhanced CT. Three patients underwent additional MRI and two patients underwent PET‐CT examinations simultaneously. The imaging features such as location, number, shape, boundary, size, internal structure, density (or signal, 18F‐fluorodeoxyglucose uptake), enhancement model and the relationship with surrounding structures were observed and compared with pathological results. Results Of the 8 patients with FDCS, 7 were located in the spleen and 1 was located in the spleen of the ectopic spleen of the pancreas. Seven patients with splenic FDCS underwent splenectomy and 1 patient with pancreatic ectopic spleen FDCS underwent resection of the pancreas. Multiple lesions were detected in 1 case, while single in the others. Tumor was round or oval. The tumors were well‐circumscribed and presented as expansive growth. On unenhanced CT, the tumors showed a slightly lower density, and hemorrhage and necrosis could be detected in 6 lesions. Calcification was seen in 1 case, significant necrosis, and cystic change was presented in the pancreatic ectopic spleen FDCS. The solid part presented isointensity or slightly hypointensity on T1WI, and hyperointensity on T2WI. Cystic necrosis areas were hypointensitive on T1WI, and hyperointensitive on T2WI. Spoke‐like areas with hypointensity on T1WI and hyperointensity on T2WI were detected in the center of the solid part with the distribution among the substantial degenerative and necrotic regions. PET‐CT showed that the 18F‐fluorodeoxyglucose was uptaked obviously. The enhancement CT showed that at the arterial phase, the tumors were markedly enhanced and continuously enhanced at portal vein phase and balance phase. Multiple liver metastases were detected in 1 case with huge FDCS. One patient was followed up for 6 years, and gastric lymphoma was detected. The others were followed up for 6 to 53 months, there remained no transfer or recurrence.Conclusions The features of FDCS of spleen mainly manifest as solid or cystic mass with clear solitary sphenoma accompanied by scarring, calcification and hemorrhage. The enhancement mode is persistent enhancement. MRI and PET‐CT help to further reflect the tumor pathological basis and biological characteristics.

ABSTRACT

Objective@#To observe continuous and intermittent application of lamivudine or entecavir resistance mutations in patients with chronic hepatitis B.@*Methods@#Data of patients with active stage of chronic hepatitis B over the past 6 years were collected and analyzed retrospectively. The incidence of drug resistance mutation and related factors between patients taking LAM or ETV continuously and intermittently were compared with those taking LAM or ETV. Data comparison was performed using χ2 test.@*Results@#Patients with HBV DNA≥105 copies / ml at the time of initial treatment had higher resistance mutation rates than those with HBV DNA < 105 copies / ml at either continuous or intermittent treatment, and patients with intermittent treatment had higher resistance mutation rates than those with continuous treatment. Simultaneously, the incidence of drug resistance mutation in LAM and ETV in the first, second and third years were significantly higher in intermittent treatment than that of continuous treatment (P < 0.05). There was a positive correlation between the frequency of drug withdrawal and the rate of drug resistance mutation. There were no individual difference and drug difference between LAM and ETV.@*Conclusion@#In the treatment of chronic hepatitis B with oral nucleoside analogues, drug resistance may occur in either continuous or intermittent treatment. When comparing continuous with intermittent treatment, it suggests that intermittent is more likely to cause viral resistance mutation.

ABSTRACT

Objective To explore the role of visual oculomotor-vestibular eye balance function in the diagnosis of central and peripheral vertigo. Methods From January 2015 to June 2016,one hundred and sixty-two patients with central vertigo who were treated at Kailuan General Hospital were enrolled in the study, including 124 males and 38 females, aged ( 64. 09 ± 10. 98 ) years old; there were 166 cases of peripheral vertigo,75 males and 91 females,aged (52. 13±12. 20) years old. Spontaneous nystagmus test,gaze test,position test, saccade test, smooth visual tracking test, visual single-speed test, visual sinus test, swivel chair rotation- emergency stop test using infrared video nystagmus and static balance posture instrument,open-closed eye hard plate erect test, open-closed eye sponge soft bottom erect test balance function electrophysiological test were conducted. Results The detection rate of pathological spontaneous nystagmus and pathological gaze nystagmus was higher in the central vertigo group than that in the peripheral vertigo group (χ2=5. 674,16. 458,P<0. 05) . The occurrence rate of positional nystagmus was higher in peripheral vertigo group than that in central vertigo group (χ2=48. 896,P<0. 001). The abnormal rate of scanning test,stable visual tracking test,visual movement single speed and sinusoidal test,and static balance posture test were higher in the central vertigo group than those in the peripheral vertigo group (χ2 =137. 169, 166. 972, 150. 877, 150. 877, 27. 273, P<0. 001 ) , while the abnormal rate of rotating chair sudden stop test was higher in the central vertigo group than that in the peripheral vertigo group (χ2=51. 000,P<0. 001) . The abnormal results were mainly scanned underflush and slow scan in central vertigo group (χ2=103. 846,4. 296,P<0. 05),stable visual tracking curve (χ2=147. 389,4. 296,P<0. 05) in type III-IV,and the gain of nystagmus decreased unilaterally and bilaterally (χ2=47. 531,44. 477, 52. 529,53. 255,P<0. 001) . Anomalies of proprioception in reverse and vertical nystagmus and static balance posture were induced by rotating chair sudden stop test (χ2=11. 847, 23. 778, P<0. 001 ) , while peripheral vertigo group showed unilateral decrease of nystagmus gain induced by rotating chair sudden stop test. (χ2=79. 771, P < 0. 001 ) . Conclusion The patients with peripheral vertigo have obvious body position spontaneous vestibular response and vestibular oculomotor system dysfunction, while the patients with central vertigo mainly have visual and oculomotor system dysfunction,and may be accompanied by vestibular oculomotor system and vestibular spinal reflex dysfunction.

ABSTRACT

Objective To analyze the hemodynamic changes of cerebral arterial collateral circulation and distal perfusion of cerebral arteries after external carotid artery occlusion (EICAO).Methods Ninety-six patients with EICAO were selected as the case group,of which 46 cases of left EICAO (group A),50 cases of right EICAO (group B) and 30 normal volunteers were selected as the control group.Color Doppler ultrasonography (TCD) was used to detect peak systolic velocity (Vs) in the middle cerebral artery (MCA),end diastolic velocity (Vd),mean blood flow velocity (Vm),pulsatility index (PI),hemodynamic parameters of arteries,and opening rate of grade Ⅰ anterior communicating artery (ACOA) and posterior communicating artery (PCOA).Results There were significant differences in Vs,Vm,Vd,and PI among group A,B and C (F =56.046,31.027,39.283,18.614,49.658,24.992,15.035,22.069,P< 0.001).The Vs,Vd,Vm,and PI of the left MCA in the group A were significantly lower than those of the left side in the control group (P<0.01);the Vs,Vd,Vm,and PI of the right MCA in the group B were significantly lower than those of the right side in the control group (P<0.01).In group A and B,the open rate of simple ACOA in the stage Ⅰ collateral circulation was 26.09% and 30.00%.The open rate of PCOA alone was 23.91% and 36.00%,respectively,and the concurrent opening rate of ACOA and PCOA was 36.96% and 30.00%,respectively,There was no significant difference in the open rate of grade Ⅰ collateral circulation among the three types of blood vessels (x2 =0.223,2.881,0.808,P=0.637,0.090,0.369).The incidence of cerebral infarction at the MCA donor site in the group A was 60.87% on the left side and 8.70% on the right side.The data of the left side was significantly higher than that of the right side (x2 =57.165,P<0.001).The incidence of cerebral infarction at the MCA in the group B was 14.00% on the left side and 60.00% on the right side,and the data of the fight side was significantly higher than that of the left side (x2 =43.436,P< 0.001).Conclusion Although there is a higher grade Ⅰ collateral circulation opening rate in patients with EICAO,the MCA blood supply area of the distal internal carotid artery is still in a state of low blood flow perfusion,and the incidence of cerebral infarction is also high,so opening the grade Ⅰ collateral circulation does not completely reduce the risk of cerebral infarction in these patients,and these patients are still at high risk of cerebral infarction.

ABSTRACT

The vocal cord polyp is easy to relapse after surgery, but if the patient has recurrence in a short term, it is necessary to consider it as postoperative vocal cord contact granuloma. If the patients with contact granuloma after surgical treatment had severe impact on the pronunciation, it is necessary to be operated and confirmed by pathology and given the treatment of acid suppression, in order to avoid postoperative recurrence.

ABSTRACT

Objective To explore the risk factors of cognitive impairment of elderly patients with cerebral infarction in order to provide the theoretical basis for the clinical intervention. Methods A total of 237 cases with senile cerebral infarction were selected as ours subjects who were hospitalized from Mar. 2010 to Jun. 2013 in Kailuan General Hospital Affiliated to Hebei United University. The general condition and medical history were recorded. The auxiliary examination was performed. Cerebral infarction was diagnosed based on the onset to diagnosis standard and MoCA scores of within 2 weeks. The patients with less than 26 MoCA score were diagnosed as cognitive dysfunction and otherwise were thought as normal. Single factor analysis methods and non conditional Logistic regression were applied to analyze the analysis. Results There was no significant difference in terms of incidence between patients with different gender. Patients with age more than 75 years old and lower education levels had the high incidence rate than those with younger age and high education levels( χ2=16. 661,5. 453;P﹤0. 05). The cognitive dysfunction incidence of patients with white collar was lower than those with blue collar(χ2 = 5. 458,P ﹤ 0. 05 ). And the cognitive dysfunction incidence of patients with hypertention,diabetes,heart disease and leukoaraiosis were higher than those without the above diseases(χ2 =28. 423,5. 621,7. 768,6. 070;P﹤0. 05). The incidence of patients smoking more was significantly higher than that of smoking less or no(χ2 =5. 045,P ﹤0. 05 ). Multiple factors and non conditional Logistic regression analysis showed that,67 Senile cerebral infarction patients occurred cognitive impairment within 2 weeks. The independent risk factors for its occurrence included age greater than 75 years( P=0. 000 ),diabetes mellitus( P=0. 043),hypertension(P=0. 000)and leukoaraiosis(P=0. 041). Conclusion There are many risk factors related to cognitive impairment after cerebral infarction occurred in the elderly. The intervention should take in many aspects and the risk factors should early found.

ABSTRACT

Objective To observe any change in the laterality index (LI) in the active volume of the hand motor cortex during rehabilitation after acute cerebral infarction and to analyze the mechanisms involved in the rehabilitation of motor function.Methods Sixteen patients with acute cerebral infarcts were administered standard but individualized rehabilitation training.Blood oxygenation-dependent functional magnetic resonance imaging (BOLD-fMRI) was used to evaluate the active volume of their hand sensorimotor cortex (SMC) and the LI,at admission and after 14 days of rehabilitation.The Fugl-Meyer motor assessment for the hand (FMA) was used to evaluate hand function.Ten healthy volunteers were recruited as a control group and subjected to a single BOLD-fMRI examination to confirm the location and the volume of the active area when performing the same rehabilitation exercises.Results The baseline LI of affected hand SMC activation was significantly smaller than that of the unaffected hand [(0.010 ±0.808) versus (0.789 ± 0.157)],but no significant difference was observed between the affected and the unaffected hands after treatment.Rehabilitation therapy significantly increased the SMC LI of affected hand activation when compared with the baseline,but no such effect was observed with the unaffected hand.In 12 patients with dysfunction of the right hand as evaluated by the FMA,the baseline LI of the affected hand was smaller than that of the unaffected hand and that of the healthy volunteers.Conclusion Rehabilitation after acute infarction can promote functional recovery.The LI of the affected hand reflects cerebral plasticity during rehabilitation after acute cerebral infarction.

ABSTRACT

Objective To prospectively investigate the association between serum uric acid concentration and the risk of brain infarction in Chinese adults.Methods In this prospective cohort study,a total of 95 738 participants (aged 18-98 years old) were included and were categorized into sex-specific quintiles according to serum uric acid concentration which were collected during 2006-2007 by health examinations.The study was followed up for an average of 4 years.We used Cox regression models to calculate hazard ratios (HR) and their 95% confidence intervals (CI).Results (1) Higher concentrations of serum uric acid were associated with older age,obesity,higher blood pressure,higher serum concentrations of total cholesterol,triglycerides,and high sensitivity C-reactive protein,smoking,alcohol drinking,history of hypertension,hyperlipidemia and atrial fibrillation,and antihypertensive medication use.(2) The incidence of brain infarction for sex-specific quintiles were 0.84% (33/3913),0.35% (14/3985),0.44%(17/3888),0.54% (21/3909),0.91% (35/3860) in women (x2 =15.676,P =0.003) and 1.18%(180/15 238),1.26% (191/15 170),1.11% (170/15 323),1.45% (221/15 216),1.82% (277/15 236)in men (x2 =36.641,P =0.000).(3) After adjusting for potential confounders,including age,body mass index,blood pressure,fasting plasma glucose,total cholesterol,triglyceride,smoking,alcohol,and medical history of major chronic conditions and antihypertensive medication use,the HR (95% CI) of brain infarction across serum uric acid quintiles were 2.06 (1.14-3.72),0.91 (0.45-1.84),1.00 (ref),1.11 (0.58-2.09),1.31(0.73-2.34) in women and 1.07 (0.86-1.34),1.02 (0.47-2.25),1.00 (ref),1.23(1.00-1.52),1.24(1.01-1.52) in men.Conclusions In this prospective cohort study,we find a U-shaped relationship between serum uric acid concentrations and brain infarction,a higher risk of developing brain infarction in association with low or high serum uric acid concentrations.Women with lowest or highest serum uric acid concentrations and men with higher serum uric acid concentrations are more likely to develop brain infarction.This probably because women have lower serum uric acid concentrations relative to men.Confirmation of our findings in larger cohorts with longer follow-up duration is warranted.
