Kidney asthenia lasting for a long time will result in blood stasis. Also, the cause of VD may have relationships with endothelin (ET), nitric oxide (NO), homocysteine (HCY), estrogen (E2), and testosterone (T). OBJECTIVE: To observed clinical curative effect of the kidney tonic, pancreas tonic, and blood tonic with promoting blood circulation components in treating kidney asthenia with blood stasis syndrome of VD. DESIGN: Case controlled study. SETTING: Geriatric Institute of Integrated Medicine, Fujian College of Traditional Chinese Medicine. PARTICIPANTS: A total of 70 patients, including 39 males and 31 females aged 60-80 years, were selected from Department of Neurology, Pingshan Hospital from May 2000 to September 2002. Diagnostic criteria were used for probable VD of the American Psychiatric Association. Diagnostic and Statistical of Manual of Mental Disorder, 4th ed (DSM-Ⅳ), 1994 revised, mini-mental state examination (MMSE), and criteria of kidney asthenia with blood stasis with mixed weak and sthenia syndrome of Guidelines of Clinical Research of New Chinese Medicine in Treating Dementia. According to score of kidney asthenia with blood stasis syndrome, they were classified to three groups: mild (n =22), moderate (n =33) and severe (n =15). All of them with complete chest X-Ray, ECG, blood chemistry and other related examinations, exclusive of cardiovascular, liver, kidney diseases, homeopathy and psychiatry diseases. And hereby we also select 30 normal people as the comparing group, having no substantial diseases in heart, brain, kidney, liver, lung and other main organic systems after medical examination. Of this group, 11 were males and 19 were females, ranging from 62 years old to 78 years old. There were no obvious differences between the above two groups in sex, age, and education level after statistical analysis. All patients observed in Pingxi Hospital, Fuzhou, from May 2000 to September 2002. METHODS: ① According to the diagnoses standard of blood stasis syndrome: 0-89: The increase in score indicated that blood stasis syndrome was getting serious. ② According to MMSE: All the test samples were evaluated, those with scores of 0-30, in which the non-educated ≤ 17, primary school ≤ 20, above middle school ≤ 24 were categorized. ③ Testing all sample's ET, E2 and T by using radioimmunoassay, the RIA kits were provided by Scientific and Technological Development Center of General Hospital of PLA. ④ Testing the level of NO by using colorimetic method. ⑤ Testing the level of HCY by using Enzyme-linked Immunoassay. ⑥ Meanwhile, analyzing the blood stasis score by comparing with every standard. The differences of data were compared by using t test and F test. MAIN OUTCOME MEASURES: ① Blood plasma ET, blood serum NO, HCY, E2 and T. ② The analyzing results obtained from comparing score of blood stasis with every indicators. RESULTS: The result analysis was including of both the 70 patients of VD with kidney asthenia and blood stasis and compared group consist of 30 healthy people. ① ET, NO, HCY and ET/NO: The levels of ET, HCY and ET/NO were increasing with pathography, while the levels of ET, NO, HCY and ET/NO were decreasing with the pathography, and the difference in statistics was significant (P < 0.01). ② The level of E2 and T: The levels of both E2, T and E2/T for male VD patients were (67.72±12.18) pg/L and (351.58±155.02) ng/L, 0.24±0.12 respectively, which were higher than the compared group [(53.96±16.13) pg/L, (471.83±143.99) ng/L, 0.12±0.00, P < 0.05]. The level of E2 in the female VD patients was lower than the compared group [(34.23±10.99), (44.81±14.65) pg/L, P < 0.05]. ③ The relationship between the score of blood stasis and each indicators: The levels of ET, ET/NO and HCY had significant positive relationship with blood stasis mark (r = 0.352, 0.754, 0.347, P < 0.05-0.01), obvious negative relationship with NO (r =-0.528, P < 0.01) and no clear relationship with female E2/T and male E2/T (r = -0.210, 0.04, P > 0.05). CONCLUSION: ① The levels of ET, HCY and ET/NO are increasing with pathography, while the level of NO is decreasing, which may be the evidence that the possibility of VD pathography may have relationship with the indicators above. ② The level of E2 increase in male's VD patients, and decrease in male's. And the decrease of the female may have relationship with the VD.展开更多

C...Purpose: Lately there is an increasing tendency of using Patient Reported Outcome Measures (PROMs) as a final indicator of the outcome of many surgical treatments in orthopaedics and in other medical specialties. Currently there are many outcome scores in orthopaedics and most of them are site specific. In the contrary there is a lack of trauma specific outcome scores. Methods: We have designed a new PROM especially for orthopaedic trauma patients, in order to measure in what extent the patients manage to return to their pre-injury state. This score uses as baseline the preinjury status of the patient and has the aim to determine the percentage of rehabilitation after treatment for any injury. Results: A total of 60 Chertsey Outcome Score for Trauma (COST) questionnaires were gathered in our outpatients department. The participants were 57% male (aged 46.81 years ± 18.5 years) and the questionnaires collected at mean 10 months post-injury. A Cronbach's Alpha value of 0.89 was identified for the whole construct. The three dimensions of the scale had good internal consistency as well (Cronbach's Alpha test values 0.74, 0.84 and 0.81 for symptoms, function and mental status respectively). Strong/moderate correlation (Spearman's Rho test 0.43-0.65) was observed between the respective physical/mental dimensions of the COST and SF-12v2 questionnaires. Conclusion: There is a need among the orthopaedic trauma society for a specific PROM of trauma. COST is a useful and easy to use tool for every trauma surgeon.展开更多

There were no obvious differences between the above two groups in sex, age, and education level after statistical analysis. All patients observed in Pingxi Hospital, Fuzhou, from May 2000 to September 2002. METHODS: ① According to the diagnoses standard of blood stasis syndrome: 0-89: The increase in score indicated that blood stasis syndrome was getting serious. ② According to MMSE: All the test samples were evaluated, those with scores of 0-30, in which the non-educated ≤ 17, primary school ≤ 20, above middle school ≤ 24 were categorized. ③ Testing all sample's ET, E2 and T by using radioimmunoassay, the RIA kits were provided by Scientific and Technological Development Center of General Hospital of PLA. ④ Testing the level of NO by using colorimetic method. ⑤ Testing the level of HCY by using Enzyme-linked Immunoassay. ⑥ Meanwhile, analyzing the blood stasis score by comparing with every standard. The differences of data were compared by using t test and F test. MAIN OUTCOME MEASURES: ① Blood plasma ET, blood serum NO, HCY, E2 and T. ② The analyzing results obtained from comparing score of blood stasis with every indicators. RESULTS: The result analysis was including of both the 70 patients of VD with kidney asthenia and blood stasis and compared group consist of 30 healthy people. ① ET, NO, HCY and ET/NO: The levels of ET, HCY and ET/NO were increasing with pathography, while the levels of ET, NO, HCY and ET/NO were decreasing with the pathography, and the difference in statistics was significant (P < 0.01). ② The level of E2 and T: The levels of both E2, T and E2/T for male VD patients were (67.72±12.18) pg/L and (351.58±155.02) ng/L, 0.24±0.12 respectively, which were higher than the compared group [(53.96±16.13) pg/L, (471.83±143.99) ng/L, 0.12±0.00, P < 0.05]. The level of E2 in the female VD patients was lower than the compared group [(34.23±10.99), (44.81±14.65) pg/L, P < 0.05]. ③ The relationship between the score of blood stasis and each indicators: The levels of ET, ET/NO and HCY had significant positive relationship with blood stasis mark (r = 0.352, 0.754, 0.347, P < 0.05-0.01), obvious negative relationship with NO (r =-0.528, P < 0.01) and no clear relationship with female E2/T and male E2/T (r = -0.210, 0.04, P > 0.05). CONCLUSION: ① The levels of ET, HCY and ET/NO are increasing with pathography, while the level of NO is decreasing, which may be the evidence that the possibility of VD pathography may have relationship with the indicators above. ② The level of E2 increase in male's VD patients, and decrease in male's. And the decrease of the female may have relationship with the VD.
文摘Background COVID-19 pandemic continues,clarifying signatures in clinical characters and antibody responses between severe and non-severe COVID-19 cases would benefit the prognosis and treatment.Methods In this study,119 serum samples from 37 severe or non-severe COVID-19 patients from the First People's Hospital of Yueyang were collected between January 25 and February 182020.The clinical features,antibody responses targeting SARS-CoV-2 spike protein(S)and its different domains,SARS-CoV-2-specific Ig isotypes,IgG subclasses,ACE2 competitive antibodies,binding titers with FcγIIa and FcγIIb receptors,and 14 cytokines were comprehensively investigated.The differences between severe and non-severe groups were analyzed using Mann–Whitney U test or Fisher’s exact test.Results Severe group including 9 patients represented lower lymphocyte count,higher neutrophil count,higher level of LDH,total bile acid(TBA)(P<1×10–4),r-glutaminase(P=0.011),adenosine deaminase(P<1×10–4),procalcitonin(P=0.004),C-reactive protein(P<1×10–4)and D-dimer(P=0.049)compared to non-severe group(28 patients).Significantly,higher-level Igs targeting S,different S domains(RBD,RBM,NTD,and CTD),FcγRIIa and FcγRIIb binding capability were observed in a severe group than that of a non-severe group,of which IgG1 and IgG3 were the main IgG subclasses.RBD-IgG were strongly correlated with S-IgG both in severe and non-severe group.Additionally,CTD-IgG was strongly correlated with S-IgG in a non-severe group.Positive RBD-ACE2 binding inhibition was strongly associated with high titers of antibody(S-IgG1,S-IgG3,NTD-IgG,RBD-IgA,NTD-IgA,and CTD-IgA)especially RBD-IgG and CTD-IgG in the severe group,while in the non-severe group,S-IgG3,RBD-IgG,NTD-IgG,and NTD-IgM were correlated with ACE2 blocking rate.S-IgG1,NTD-IgM and S-IgM were negatively associated with illness day in a severe group,while S-IgG3,RBD-IgA,CTD-IgA in the severe group(r=0.363,P=0.011)and S-IgG1,NTD-IgA,CTD-IgA in the non-severe group were positively associated with illness day.Moreover,GRO-α,IL-6,IL-8,IP-10,MCP-1,MCP-3,MIG,and BAFF were also significantly elevated in the severe group.Conclusion Antibody detection provides important clinical information in the COVID-19 process.The different signatures in Ig isotypes,IgG subclasses,antibody specificity between the COVID-19 severe and non-severe group will contribute to future therapeutic and preventive measures development.
文摘Increased QT dispersion in the surface ECG (QTd = QTmax minus QTmin) is considered as an indicator of electrical inhomogeneitv and a useful predictor for severe ventricular arrhythmia and sudden cardiac death in patients with different heart diseases. Patients with ischemic and idiopathic cardiomyopathy have a very high incidence of severe ventricular arrhythmia and sudden cardiac death. We compared QT, QTc. JT and JTc dispersion in ischemic (ICMP) and idopathic (CCMP) cardiomyopathy patients with and without severe ventricular arrhythmia and normal controls.
文摘Objective To explore risk factors,clinical characteristics and prognosis of CMV enteritis combined with severe intestinal graft-versus-host disease(GVHD).Methods The data of 80 intestinal gradeⅢ/ⅣGVHD patients from January 2005 to September 2015 in hematology of PKUPH were retrospectively analyzed.All patients received colonoscopy and all GVHD diagnoses
文摘Purpose:The mortality rate for severely injured patients with the injury severity score(ISS)>16 has decreased in Germany.There is robust evidence that mortality is influenced not only by the acute trauma itself but also by physical health,age and sex.The aim of this study was to identify other possible influences on the mortality of severely injured patients.Methods:In a matched-pair analysis of data from Trauma Register DGU(R),non-surviving patients from Germany between 2009 and 2014 with an ISS_>16 were compared with surviving matching partners.Matching was performed on the basis of age,sex,physical health,injury pattern,trauma mechanism,conscious state at the scene of the accident based on the Glasgow coma scale,and the presence of shock on arrival at the emergency room.Results:We matched two homogeneous groups,each of which consisted of 657 patients(535 male,average age 37 years).There was no significant difference in the vital parameters at the scene of the accident,the length of the pre-hospital phase,the type of transport(ground or air),pre-hospital fluid management and amounts,ISS,initial care level,the length of the emergency room stay,the care received at night or from on-call personnel during the weekend,the use of abdominal sonographic imaging,the type of X-ray imaging used,and the percentage of patients who developed sepsis.We found a significant difference in the new injury severity score,the frequency of multi-organ failure,hemoglobine at admission,base excess and international normalized ratio in the emergency room,the type of accident(fall or road traffic accident),the pre-hospital intubation rate,reanimation,in-hospital fluid management,the frequency of transfusion,tomography(whole-body computed tomography),and the necessity of emergency intervention.Conclusion:Previously postulated factors such as the level of care and the length of the emergency room stay did not appear to have a significant influence in this study.Further studies should be conducted to analyse the identified factors with a view to optimising the treatment of severely injured patients.Our study shows that there are significant factors that can predict or influence the mortality of severely injured patients.
文摘Purpose: Lately there is an increasing tendency of using Patient Reported Outcome Measures (PROMs) as a final indicator of the outcome of many surgical treatments in orthopaedics and in other medical specialties. Currently there are many outcome scores in orthopaedics and most of them are site specific. In the contrary there is a lack of trauma specific outcome scores. Methods: We have designed a new PROM especially for orthopaedic trauma patients, in order to measure in what extent the patients manage to return to their pre-injury state. This score uses as baseline the preinjury status of the patient and has the aim to determine the percentage of rehabilitation after treatment for any injury. Results: A total of 60 Chertsey Outcome Score for Trauma (COST) questionnaires were gathered in our outpatients department. The participants were 57% male (aged 46.81 years ± 18.5 years) and the questionnaires collected at mean 10 months post-injury. A Cronbach's Alpha value of 0.89 was identified for the whole construct. The three dimensions of the scale had good internal consistency as well (Cronbach's Alpha test values 0.74, 0.84 and 0.81 for symptoms, function and mental status respectively). Strong/moderate correlation (Spearman's Rho test 0.43-0.65) was observed between the respective physical/mental dimensions of the COST and SF-12v2 questionnaires. Conclusion: There is a need among the orthopaedic trauma society for a specific PROM of trauma. COST is a useful and easy to use tool for every trauma surgeon.
