ABSTRACT
Objective:To describe the clinical features of a patient of anti-neurofascin 186 (NF186) antibody associated acute immune sensory polyradiculopathy (AISP), and enhance understanding of AISP/chronic immune sensory polyradiculopathy (CISP).Methods:The clinical characteristics, diagnosis and treatment of a domestic AISP patient with NF186 antibody positive admitted to the First Hospital of Shanxi Medical University in December 2021 were summarized, and the previously reported cases of AISP/CISP were systematically reviewed.Results:The patient was a 62-year-old male with acute onset. The clinical manifestations included severe sensory ataxia, increased protein in cerebrospinal fluid, no response to stimulation of the central segment of somatosensory evoked potentials (SEP), normal sensory and motor nerve conduction, and positive serum anti-NF186 antibody (1∶32). After glucocorticoid treatment, the clinical symptoms and SEP were significantly improved. The drug was stopped for 2 months, and there was no recurrence. There were 23 cases of AISP and CISP with complete data reported in the literature (including this patient). The age of onset was (54.7±17.7) years, and the ratio of male to female was 1.88. Three patients with acute onset were classified as AISP. A total of 95.7% (22/23) of patients showed sensory ataxia without limb weakness, 95.0% (19/20) of patients showed prolonged cortical potential latency or even no response, and 95.5% (21/22) of patients showed increased cerebrospinal fluid protein in varying degrees, and nerve root thickening or abnormal enhancement was not common. All 10 patients receiving immunotherapy responded to corticosteroids or intravenous immune globulin. Only 6 AISP/CISP articles reported screening for anti-ganglioside antibodies or Ranvier′s node-paranodal region-related antibodies, and no positive NF186 antibodies were reported. All the 3 patients with AISP had some characteristics of CISP/chronic inflammatory demyelinating polyradiculoneuropathy, and there was no significant difference between AISP and CISP patients in clinical features except the mode of onset.Conclusions:NF186 antibody could cause AISP, which presents as acute onset sensory ataxia. AISP is responsive to glucocorticoid therapy. Except for the mode of onset, AISP and CISP are difficult to distinguish from clinical, electrophysiological, pathological aspects and pathogenic antibodies, so they may be two different manifestations of the same disease.
ABSTRACT
Objective:To explore the correlation between cerebrovascular hemodynamic index (CVHI) accumulative score and subclinical arteriosclerosis indicators.Methods:A total of 27 184 cases were collected from the Health Management Center,the Third Xiangya Hospital,Central South University.Linear regression analysis was carried out to confirm the correlations between CVHI accumulative score and the modified Framingham stroke profile (FSP),as well as between CVHI accumulative score and cerebrovascular diseases (ICVD) scale.The correlation between CVHI accumulative score and brachial-ankle pulse wave velocity (baPWV),carotid plaque orcarotid intima-media thickness (CIMT) was analyzed by multifactor logistic regression model in 11 580 cases.Moreover,the correlation between CVHI accumulative score and microalbuminuria or serum cystatin C was performed by multifactor logistic regression model in 9 860 cases.Results:In this study,the people whose CVHI accumulative score was less than 75 accounted for 12.98％.The CVHI accumulative score was negatively related with the modified FSP score (r=-0.484,P＜0.01) or ICVD score (r=-0.455,P＜0.01).The multifactor logistic regression model found that the baPWV,carotid plaque,microalbuminuria and serum cystatin C were independent predictors for CVHI accumulative score.Conclusion:The CVHI accumulative score is correlated with the modified FSP score,ICVD score and indexes of subclinical arteriosclerosis (baPWV,carotid plaque,microalbuminuria and serum cystatin C).The CVHI accumulative score could be used as a tool for zero-level and primary prevention of cerebral stroke.
ABSTRACT
Total 1 500 subjects aged over 60 years were selected from 10 community health service centers with cluster sampling method.A questionnaire survey and physical examination were performed in all subjects.Sixty five patients with chronic heart failure were detected.The questionnaire showed that 77.6％ (38/49)patients were diagnosed in tertiary hospitals,and 12.2％ (6/49) were diagnosed in community hospitals.When heart failure occurred,most patients (37.7％,20/53) chose to take a taxi to the tertiary hospital directly,and less patients (17.0％,9/53)contacted community doctors.When a heart attack happened,68.8％ (33/48)of the patients could reach the hospital within 30 min,and 55.3％ (26/47) within 60 min.45.7％ (21/46) elderly patients were hospitalized for heart failure once a year;31.1％ (14/45) were in hospital for less than 10 d each time.46.0％ (23/50) heart failure patients had received health education and 40.0％ (16/40) had taken drugs under supervision;the majority health educators were community doctors and majority supervisors were family members.The results suggest that the confirmed diagnosis and treatment of heart failure patients still rely on tertiary hospitals,community health institutions play an important role in health education and management of heart failure patients outside hospitals.But the utilization of community health services is still not enough in community health service centers.
ABSTRACT
Objective To explore the reporting process of our health risk warning system and its long-term effectiveness.Methods A total of 1 168 individuals who were identified as higher risk populations from July 2011 to June 2012 in our Health Mangement Center were served as the control group,and another 973 adults who were identified as higher risk individuals from July 2012 to May 2013 were assigned to the study group.Diagnosis and treatment were based on our health risk reporting process and follow-up system.Paired t test and paired contingency table x2 test were used for data analysis.Results The rate of follow-up (97％ vs 100％,x2=30.503,P＜0.05),consultation (83.48％ vs 93.63％,x2=52.142,P＜ 0.05),mean treatment time ((3.0±0.5) vs (1.5±0.5) d,t=69.12,P＜0.05) and patient satisfaction (87.84％ vs 96.20％,x2=48.361,P＜0.05) were significantly different between the two groups,although no statistically significant difference of incidence of adverse events was found (0.26％ vs 0.10％,x2 =0.102,P＞0.05).Conclusion Our health risk warning system may reduce the time for physical examination and improve disease diagnosis level and patients' satisfaction.Moreover,our health manatement system and health service quality should further be improved in practice.
ABSTRACT
Objective To evaluate the abstinence rate and relapse rate of smoker with ACS after discharged from hospital, to evaluate the effect of simple smoking cessation interventions.Methods 150 smokers with ACS were collected and was divided into simple intervention group ( n = 87) and control group (n = 63) , respectively, followed up for 6 months.2 months, 6 months abstinence rate, relapse rate were compared between two groups, logistic regression model was used to analyzed the relevant factors for relapse.Results The smoking rate in patients with ACS was 31.14% , 6-month continuous abstinence rate and 6-month relapse rate was 64.6% , 36.4% , respectively.6-month continuous abstinence rate and relapse rate between simple quit-smoking intervention group and control group showed no difference.Nicotine dependence score more than 4 points can be used as predictor of relapse.Conclusions The smoking rate and the abstinence rate of smoker with ACS is higher than the general population, simple quit-smoking intervention do not increase the success rate of quit-smoking, indicated the need to strengthen the intervention in patients with ACS and smoking.
ABSTRACT
Objective To investigate blood level of triglyceride(TG)in community residents of urban and rural Beijing.Methods A total of 10 054 community residents were recruited by cluster samphng for investigation using questionnaire,as well as physical examinations and fasting plasma TG determination for diagnosing hypertriglyceridemia,during June to August,2007.Results Median of plasma level of TG of the participants was 1.17 mmol/L,ranging(0.81-1.78)mmoVL Totally,1234 people were diagnosed as borderline hypertriglyceridemia and 15 12 as hypertriglycefidemia.with prevalence of 12.27%and 15.04%,respectively.There was no significant difference in plasma level ofTG between men andwomen[1.16(0.80-1.84)mmol/L vs.1.18(0.81-1.75)mmol/L,P:0.187].Age-adjusted prevalence of borderline hypertriglyceridemia and hypertriglyeeridemia was higher in men than those in women(11.60% vs.10.90%and 20.32% vs.10.88%,respectively),and the same results were obrained in those less than 50 years old,however,reveraw outcomes were got in those more than 50 years old.Plasma level of TG,as well as prevalence of hypertriglyceridemia,were higher in those living in urban areas than those in rural areas[1.31(0.89-1.95)mmol/L vs.1.05(0.73-1.58)mmol/L].Awareness,proportion of people with hyperglycefidemia under treatment and proportion of those with TG under coutrol were 13.95%.35.92%and 38.51%,respectively.Standardized prevalence of borderline hyperglycefidemia and hyperglycefidemia were higher in those with coronary heart disease than those without it(24.79% vs.11.22%and 25.31% vs.15.35%,respectively).Conclusions Awareness,proportion of treatment and proportion of those under control for hyperglyceridemia were all lower in community residents of Beijing.Education and monitoring on hyperglyeeridemia should especially be strengthened for urban residents,women aged more than 50 years,and these with coronary heart disease.
ABSTRACT
OBJECTIVE To compare two different procedures of blood donation in volunteer donors,which lead to different discard rates of blood,different donation reaction rates and the satisfaction of the donor agency,so as to seek the better procedure bringing less discard of blood and more convenience for the military donor agency and blood center. METHODS In group A,3 667 donors blood was collected before the tests and retests for transfusion transmitted diseases(TTD) were done.While in group B,4 185 donors were taken blood samples for pre-donation test.The blood collection was performed 4 hours later. RESULTS In group A,3 652 units of blood were collected,of which 69 units were discarded on account of positive results in test and retest.Meanwhile,in group B 3 718 units of blood were collected from the donors who passed the pre-donation test for TTD.As a result,34 units of blood were discarded because of the positive results in retest.The discard rates of blood were 1.89% and 0.91% while the donation reaction rates were 2.22% and 3.98%,respectively.in two procedures.The discard rates of blood in group A were higher than those in group B.But the donation reaction rate in group B was higher than that in group A. CONCLUSIONS The discard rate of blood in the procedure collecting before test is higher than that in the procedure testing before collection.But the donation reaction rate is low and the waiting period for donation is short in the former procedure,which is suitable for low TTD infections population of military agencies.
