BACKGROUND: The elevation of plasma fibrinogen(Fbg) is a key risk factor of cerebrovascular diseases. The evaluation of the monomer polymerization function of fibrin has even more important clinical merit than the detection of Fbg level.OBJECTIVE: To investigate the clinical significance of the monomer polymerization function of fibrin in patients with isehemie cerebrovascular diseases and its impacts on rehabilitative intervention.DESIGN: A case control study employing patients and healthy individual as subjects.SETTING: An Institute of Hematology and Department of Neurology of one university.PARTICIPANTS: Totally 110 patients with different ischemic cerebrovascular disease selected from the Department of Neurology, Union Hospital of Tongji Medical College, Huazhong Science and Technology University from September 2001 to March 2002, and 50 healthy individuals were included in the study.METHODS: Rehabilitative intervention was performed in 31 randomly selected cerebral infarct patients, and the parameters indicating the monomer polymerization functions of fibrin in the plasma were detected by the measurement system for the monomer polymerization function of fibrin.MAIN OUTCOME MEASURES: Abnormal condition of monomer polymerization function of fibrin in each parameter.RESULTS: Each parameter indicating the monomer polymerization functions of fibrin in plasma was significantly increased in ischemic cerebrovascular diseases patients than healthy individuals( P ＜ 0.01 ) . The abnormal rate of Fbg leveland fibrin monomer polymerization velocity (FMPV) was significantly elevated in ischemic cerebrovascular disease patients than healthy individuals ( P ＜ 0. 01 ) . The relative risk(RR) of ischemic cerebrovascular diseases in patients with abnormal FMP functions was 4 to 31 times more than healthy control group. In cerebral infarct group, FMPV of anterior circulation infarct subgroup was significantly elevated than that of posterior circulation infarct and lacunar cerebral infarct subgroups( P ＜ 0.05). The FMP function of anterior cerebral infarct patients was significantly higher than that of healthy group before rehabilitative intervention. Although each FMP parameter reduced after rehabilitative intervention, the difference between was not significant compared with that of before therapy.CONCLUSION: FMP function analysis can completely and objectively reflect the coagulation status of the patients with ischemic cerebrovascular diseases, and it can also reflect the range and severity of infarct to some extent. Although common rehabilitative intervention cannot effectively improve the high-coagulation of the blood, the impacts of specific rehabilitative intervention on the coagulation mechanism deserve further investigation.

Objective To explore the relationship between vicarious traumatization and personality in trauma helpers. Methods Questionnaire about vicarious traumatization and Revised eysenck personality questionnaire short for Chinese(EPQ-RSC) have been carried out on a random sample of 86 trauma helpers in Wenchuan earthquate region from Tangshan. And all the data of the questionnaire scales will be dealt with by the software SPSS11.5. Results ( 1 ) There were significant gender differences on vicarious traumatization of trauma helpers in emotional reaction( famale :20.03 ± 4.92; male: 15.09 ± 3.93 ), behavioral reaction ( famale: 16. 43 ± 4. 49;male: 12.11 ± 2.57 ), cognitional reaction( female: 10.27 ± 3.28; male: 8.29 ± 2.81 ), faith of life ( famale: 14.17± 3.53; male: 11.20 ± 3.37 ), physiological reaction ( female: 21.23 ± 5.31; male: 17.32 ± 4.80) and the total core of vicarious traumatization( famale: 82.70 ± 17.74; male: 64.00 ± 12.49) (P＜0.01). (2) There were significant differences of vicarious traumatization of trauma helpers on professional training and experience of trauma help (P ＜ 0.05 ). ( 3 ) Comparing to helpers of non-vicarious traumatization, the helpers of vicarious traumatization were high in N scale questionnaire (P＜ 0.01 ). Conclusion Vicarious traumatization of trauma helpers are affected by sex, professional training and experience of trauma help. The best choice of trauma helper is steady emotion personality..

Objective To evaluate the association of COX2 genetic variants with the risk of esophageal cancer and the interaction of COX2 genetic variants with Hp infection. Methods A total of 119 patients with esophageal cancer and 238 frequency-matched controls were genotyped by polymerase chain reaction-restriction fragment length polymorphism method. Odds ratios (OR) and 95% confidence intervals ( CI) were estimated by logistic regression. Results Case-control analysis showed an increased risk of developing esophageal cancer for 1195 GA(OR =2.69,95% CI= 1. 46-5. 14) and 1195AA ( OR = 2. 30,95% CI = 1.23-4. 89) genotype carriers,respectively, compared with non 1195 GG carriers. When stratified by Hp status, the significantly increased risk of esophageal cancer was found among Hp carrier with OR (95%CI) =2.74 (1.35-5.96) ,but not among Hp non-carriers. Conclusion Genetic polymorphism in COX2 promoter region may play an important role in esophageal cancer by Hp infection.

In order to investigate the association of fibrin monomer polymerization function (FMPF) with traditional cerebrovascular risk factors and ischemic cerebrovascular disease in old people, 1:1 paired case-control comparative study was performed for FMPF and traditional cerebrovascular risk factors on 110 cases of old ischemic cerebrovascular disease and 110 controls matched on age, sex and living condition. The results showed that cerebrovascular risk factors were more prevalent in case group than in control group. In the case group, FMPF was significantly higher than in control group. There was a significant positive correlation between hypertension and fibrin monomer polymerization velocity (FMPV), hypertension and fibrinogen (Fbg), alcohol consumption and Fbg, but no significant correlation between diabetic mellitus, smoking and FMPF was found. Among the parameters of blood lipids, there were significant positive correlations between total cholesterol (TC) and parameters of FMPF to varying degrees, triglycerides (TG) and FMPV, TG and Fbg. Our results also showed there were significant linear trends between TC and FMPV (P < 0.001), TC and Fbg (P = 0.0087), TG and FMPV/Amax (maximum absorbance) (P = 0.0143) respectively. Multiple logistic regression analysis revealed that FMPF in case group remained significantly higher than control group after adjustment of all risk factors that were significant in univariate analysis. It was concluded that there is a possible pathophysiological link between FMPF and cerebrovascular risk factors. An elevated FMPF is associated with ischemic cerebrovascular disease and an independent risk factor of this disease. In old people, detection of FMPF might be a useful screening to identify individuals at increased cerebrothrombotic risk.

Objective To evaluate the efficacy and safety of solifenacin in patients with overactive bladder (OAB). Methods A multicenter clinical trial was conduced. 216 patients with OAB were enrolled. All the patients received solifenacin(5 mg once daily). With 5 weeks'treatment, all the patients recorded the diary and the adverse events as well. The symptoms of urgency, frequency, nocturia, urine volume, incontinence were evaluated. The results of the efficacy and safety were analyzed by using SPSS 13. 0. Results After 5 week treatments, all the index obviously improved(P<0.05). 187 cases (86.7%)were cured and 43 cases recovered normal voiding, 29 cases improved obviously. 11cases(5.0 %)reported adverse effect as dry mouth, dry eye. Conclusion Solifenacin could be the safe and effective drug in the treatment of OAB patients.

Alzheimer's disease (AD) is one of the major diseases that harmful to healthy elderly, and mild cognitive impairment (MCI) is the early clinical stage of AD. There is a lag in the clinical diagnosis of both diseases. An objective and reliable auxiliary diagnostic method is urgently needed to provide early diagnosis and differential indicators for AD and MCI, to predict the probability of individuals suffering from AD and MCI transforming into AD, and to reduce the overall incidence of AD and reduce the huge medical and economic burden for the country and society. Event-related potential is widely used in AD and MCI, and the resolution at the millisecond level can truly reflect the time course of cognitive processing and the degree of impairment of cognitive function in patients. In this study, we investigated the differences in the amplitude and latency of ERP components in healthy elderly, MCI and AD patients, and the correlation between ERP components and cognitive impairment. Early N170 and P200 showed high sensitivity and specificity in differentiating MCI from healthy elderly or MCI from AD. The late perception-related ERPs also showed high sensitivity and specificity in differentiating healthy elderly from MCI/AD. The differences in ERPs between MCI and AD may be related to the etiology, the degree of disease progression and the site of brain damage. The specific brain mechanism still need to be further explored and will be the focus of future research. With the progress of the research, the relationship between the specific ERP manifestations and the mechanism of brain injury as well as the impairment of cognitive function will be more clear. It is believed that the application of ERP in clinical will bring more benefits to AD and its early clinical MCI.

AIM:To determine the link between infliximab,adalimumab,vedolizumab,ustekinumab and risk of lymphoma in order to provide reference for the safety of clinical application.METHODS:Dis-proportionality analysis and Bayesian analysis were used in data mining to screen the suspected lym-phoma after the use of four biological agents based on the FAERS data from October 2012 to June 2023.The fatality and hospitalization rates of this four biological agents associated lymphoma were also investigated.RESULTS:Totally 705 cases of four biological agents associated lymphoma were collected.Four biological agents associated lymphoma appeared to influent more young pa-tients and middle-aged patients than elderly pa-tients(25.11％vs.22.41％vs.12.2％).There were slightly more male than females(42.84％vs.35.60％).Infliximab has the highest reporting odds ratio[ROR3.40,95％CI=(3.03,3.82)],proportional ratio[PRR3.38,95％CI=(3.01,3.79)],information component(IC1.14,IC-2SD=1.02)and empirical Bayes geometric mean(EBGM2.21,EBGM05=2.01).Significant difference in the fatality rate and hospi-talization rate among four biological agents were not found.CONCLUSION:Infliximab showed a strongest lymphoma association than the other three biological agents.Lymphoma risk should be vigilant when using infliximab.
