ABSTRACT

This study aimed to define the most consistent white matter microarchitecture pattern in Parkinson's disease (PD) reflected by fractional anisotropy (FA), addressing clinical profiles and methodology-related heterogeneity. Web-based publication databases were searched to conduct a meta-analysis of whole-brain diffusion tensor imaging studies comparing PD with healthy controls (HC) using the anisotropic effect size-signed differential mapping. A total of 808 patients with PD and 760 HC coming from 27 databases were finally included. Subgroup analyses were conducted considering heterogeneity with respect to medication status, disease stage, analysis methods, and the number of diffusion directions in acquisition. Compared with HC, patients with PD had decreased FA in the left middle cerebellar peduncle, corpus callosum (CC), left inferior fronto-occipital fasciculus, and right inferior longitudinal fasciculus. Most of the main results remained unchanged in subgroup meta-analyses of medicated patients, early stage patients, voxel-based analysis, and acquisition with 30 diffusion directions. The subgroup meta-analysis of medication-free patients showed FA decrease in the right olfactory cortex. The cerebellum and CC, associated with typical motor impairment, showed the most consistent FA decreases in PD. Medication status, analysis approaches, and the number of diffusion directions have an important impact on the findings, needing careful evaluation in future meta-analyses.

ABSTRACT

Objective:To observe the effect of Fangji Huangqitang (FJHQT) on collagen induced arthritis (CIA) and synovial angiogenesis in DBA/1 mice. Method:DBA/1 mice were randomly divided into normal group, CIA group and FJHQT group. DBA/1 mice in CIA group and FJHQT group were immunized with bovine type Ⅱ collagen and complete Freund's adjuvant on the first day, and DBA/1 mice were immunized with bovine type Ⅱ collagen and incomplete Freund's adjuvant on the 21<sup>st</sup> day to establish CIA model. On the day of the second immunization, the drug was given by gavage once a day for 28 days. On the 22<sup>nd</sup> day, the arthritis score and other symptoms of CIA mice were observed. On the 49<sup>th</sup> day, Hematoxylin eosin (HE) staining was carried out to observe the angiogenesis in the synovium of CIA mice, the expression of vascular endothelial cell marker platelet endothelial cell adhesion molecule-1 (CD31) and vascular endothelial growth factor (VEGF) in the synovium of CIA mice were detected. Immunofluorescence double staining was used to detect the mature and immature vessels in the synovium of CIA mice. And the microvascular growth of the rat thoracic aortic ring was induced by VEGF (20 μg·L<sup>-1</sup>). The effects of FJHQT (0.25, 0.5, 1 g·L<sup>-1</sup>) at different concentrations were observed under microscope. Result:Compared with the normal group, the inflammation, joints, red and swelling of the inflammatory joints of the CIA group were significantly increased (<italic>P</italic><0.01). The scores of clinical arthritis, the incidence rate, synovial inflammation and angiogenesis were significantly increased (<italic>P</italic><0.01). The density of blood vessels, the positive expression of CD31 and VEGF, the number of immature vessels in synovial membrane were significantly increased (<italic>P</italic><0.01). And compared with the CIA group, the inflammation, joint swelling, and malformation of the FJHQT group were significantly improved, the clinical arthritis score, incidence rate, synovial inflammation and angiogenesis were significantly reduced (<italic>P</italic><0.01). The vascular density, the positive expression of CD31 and VEGF, and the number of immature blood vessels in synovial membrane were significantly increased (<italic>P</italic><0.01). Compared with blank group, VEGF could significantly induce the growth of microvasculature in rat thoracic aortic ring (<italic>P</italic><0.01). Compared with VEGF group, FJHQT(0.25, 0.5, 1 g·L<sup>-1</sup>) could significantly inhibit the formation of microvasculature in rat thoracic aortic ring (<italic>P</italic><0.01). Conclusion:FJHQT can effectively alleviate the clinical symptoms and condition of CIA mice, reduce the clinical arthritis score and incidence rate,and inhibit the synovial angiogenesis of CIA mice joints and VEGF induced microvascular formation in rat thoracic aortic rings.

ABSTRACT

Objective:To explore the relationship between executive functioning and community integration after a traumatic brain injury and to identify the main factors influencing community integration.Methods:A cross-sectional study of 30 traumatic brain injury survivors was conducted recording their gender, age, years of education, days in coma, living status and mobility. Their executive functioning was assessed using the Disorders of Executive Function Questionnaire (DEX) and the Wisconsin Card Sorting Test (WCST). Their community integration was evaluated using the Community Integration Questionnaire (CIQ). The independent correlations of demographic characteristics, life status, mobility and executive functioning with CIQ score were quantified.Results:The average total CIQ score was negatively correlated with the average WCST-RP, DEX and WCST-RPE scores, but it was positively correlated with mobility. It was also significantly correlated with life status. DEX scores and WCST-RP scores were significant independent predictors of community integration. The average CIQ family integration score was negatively correlated with days spent in a coma and significantly correlated with living status. The average CIQ social integration score was positively correlated with mobility (and negatively correlated with DEX, WCST-RP and WCST-RPE score. WCST-RP score and mobility were significant independent predictors of CIQ social integration scores. The average CIQ productive activity scores correlated negatively with the DEX, WCST-RP and WCST-RPE scores, and with the DEX and WCST-RP executive function scores. They were significant independent predictors of CIQ productive activity scores.Conclusions:Executive functioning can predict community integration, especially its social integration dimension.

ABSTRACT

OBJECTIVE@#To evaluate the value of autism screening checklists in the early identification of autism spectrum disorder (ASD).@*METHODS@#A total of 2 571 children who attended the Children's Hospital of Chongqing Medical University and completed autism screening and diagnostic test were enrolled as subjects, among whom 2 074 were diagnosed with ASD, 261 were diagnosed with global developmental delay (GDD), 206 were diagnosed with developmental language disorder (DLD), and 30 had normal development. The sensitivity, specificity, and optimal threshold value of the Modified Checklist for Autism in Toddlers (M-CHAT) and the Autism Behavior Checklist (ABC) for the early identification of ASD were evaluated by the receiver operating characteristic (ROC) curve.@*RESULTS@#The M-CHAT had a high sensitivity of 88.3% but a low specificity of 36.0% for the identification of ASD. Its sensitivity decreased with age, and was maintained above 80% for children aged 16 to < 48 months. The ABC had a high specificity of 87.3% but a low sensitivity of 27.2%, with an optimal cut-off value of 47.5 based on the ROC curve analysis. The multivariate linear regression model based on a combination of the M-CHAT and ABC for screening of ASD showed a specificity of 85.8% and a sensitivity of 56.6%.@*CONCLUSIONS@#The M-CHAT has a high sensitivity and a low specificity in the identification of ASD, with a better effect in children aged 16 to < 48 months. The ABC has a high specificity and a low sensitivity. The multiple linear regression model method based on the combined M-CHAT and ABC to screen ASD appears to be effective.

ABSTRACT

Objective:To analyze the phenotype and genotype of a Chinese pedigree with congenital dysfibrinogenemia and investigate the molecular mechanism of the disease.Methods:Pedigree analysis. Peripheral blood samples were collected from 7 members of the pedigree and routine coagulation tests were conducted. The activity of fibrinogen was measured using Clauss method, and fibrinogen antigen was measured by immunoturbidimetry. All the exons and exon-intron boundaries of FGA, FGB and FGG genes were amplified using PCR, which was followed by direct sequencing. Electrophoretic and immunological analysis of fibrinogen, fibrinogen clottability measurement, fibrin polymerization measurement and scanning electron microscopy were used to investigate the pathogenesis of this disease. Results:The proband showed normal activated partial thromboplastin time (APTT) , prolonged prothrombin time(PT), thrombin time (TT),and reptilase time (RT).The antigen level of fibrinogen in the proband (1.6 g/L) decreased slightly, while the activity level of fibrinogen (0.7 g/L) decreased significantly. His father and grandmother showed normal APTT and PT, prolonged TT and RT. The antigen levels of fibrinogen in both of them were normal (2.0 g/L and 2.2 g/L, respectively), while the activity levels of fibrinogen were low (1.0 g/L and 1.1 g/L, respectively). The results of other members from the pedigree were all within the normal range. Genetic analysis revealed a heterozygous A>G mutation at nucleotide 4774 in exon 6 of FGG gene in the proband, which was predicated to be a novel Gln195Arg mutation. The mutation was also found in his father and grandmother.Western blot results showed that no abnormal bands of plasma fibrinogen were found in the proband, his father and grandmother. The fibrinogen clottability in the proband was 49.3%, while that in the heathy control was 98.9%. Both thrombin-induced fibrin polymerization and reptilase-induced fibrin polymerization were significantly impaired in the proband, compared to that in the heathy control. Scanning electron microscopy revealed that compared with the heathy control, the average fiber diameters of the fibrin clot in the proband increased significantly ( P<0.001), while the density of fibers decreased and the arrangement of fibers was sparse. Conclusions:The heterozygous Arg19Gly mutation, which probably damages functions of fibrinogen, should be responsible for the congenital dysfibrinogenemia in this pedigree. This mutation has not been reported.

ABSTRACT

Objective:To establish clinical detection of coagulation factor Ⅷ activity by chromogenic substrate assay and evaluate its clinical application.Methods:A total of 40 hemophilia Apatients, 20 acquired hemophilia A patients, 26 patients with positive lupus anticoagulant and 60 apparently healthy people were enrolled from January 2018 to May 2019 in Ruijin Hospital of Medical College, Shanghai Jiaotong University. According to Clinical and Laboratory Standards Institute(CLSI), the accuracy, within-run and between-run imprecision, lower detection limit, linear range, carryover rate, reference range, and reportable range of chromogenic substrate assay for detecting coagulation factor Ⅷ activity was evaluated, and compared with coagulation assay. The clinical application was evaluated by detecting F Ⅷ activity in acquired hemophilia A patients and patients with lupus anticoagulant by chromogenic substrate assay.Results:The results of two constant quality control products were within range provided by the manufacturer(the bias was 3.93%-6.79%). The within-run imprecision was 1.86%-2.06%(≤5%). The between-run imprecision was 4.83%-6.90%(≤15%). The chromogenic substrate assay had a good performance in sensitivity(CV=11.23%<20%). The recommended reference range was appropriate for our laboratory. The maximum dilution was 1∶16. The linear range was 5.00%-193.50% (a=1.0243, R 2=1.000). The clinical reportable range was 0.50%-387.00%. The method had a low carryover rate (0.04%). The chromogenic substrate assay had good consistency with coagulation assay in detecting coagulation factor Ⅷactivity (R 2=0.961) as well as the titer of FⅧ inhibitor(R 2=0.973).The difference of FⅧ activity in patients with lupus anticoagulant between these two assays was statistically significant(t=9.232,P<0.05). Conclusion:The chromogenic substrate assay has a good performance in clinical detection of coagulation factor Ⅷactivity with wider clinical application and less interference.

ABSTRACT

Objective:To evaluate the reliability of flow cytometry (FCM) for diagnosing lymphoma associated hemophagocytic syndrome (LAHS).Method:The clinical data in 57 patients with hemophagocytic lymphohistiocytosis (HLH)were retrospective analyzed at Peking University Shenzhen Hospital from July 2010 to July 2019. All patients were performed bone marrow FCM and bone marrow pathological examination before final diagnoses were made. The golden diagnosis criterion was based on clinical, biochemical and histopathological evidence, which was regarded as the standard to evaluate the sensitivity and specificity of FCM analysis in diagnosing LAHS.Results:Among 57 cases, 36 cases were eventually diagnosed with LAHS, including 15 B-cell lymphoma(14 diffuse large B-cell lymphoma, 1 B-cell lymphoma with reactive T-cell hyperplasia), 13 aggressive NK/T cell lymphoma/leukemia, 2 cases of gamma-delta T-cell lymphoma, 4 angioimmunoblastic T-cell lymphoma, 1 enteropathy-associated peripheral T-cell lymphoma and 1 anaplastic T-cell lymphoma. Lymphoma cells in bone marrow were detected in all patients by FCM except one ENTCL patient. The sensitivity and the specificity of FCM in LASH compared to bone marrow biopsy were 97.2%( P=0.014)and 90.5%( P=0.488) respectively. In the other 21 non-LAHS patients, T cell receptor Vβ (TCRVβ) rearrangement was detected in 2 patients with Epstein-Barr virus (EBV) associated primary HLH. Conclusions:FCM effectively detects lymphoma cells in bone marrow of lymphoma patients with LHL, suggesting that FCM could be an important indicator for the diagnosis of LAHS. FCM also has the advantage in differentiating LAHS from other HLH.

ABSTRACT

Objective:To analyze the survival and prognostic factors of adult acute lymphoblastic leukemia (ALL) with different consolidation regimens after complete remission by induction therapy.Methods:A total of 93 adult patients with ALL were enrolled from January 2012 to June 2019 in Peking University Shenzhen Hospital. All the patients achieved complete remission induced by VDLCP regimen, and were divided into the standard group, intensive group and transplantation group according to the consolidation treatment. Thirty-four patients in the standard group received an ALL-like chemotherapy regimen based on VDLCP or Hyper-CVAD consolidation for 4-6 courses. Twenty-nine patients in the intensive group received BFM90/95 consolidation treatment for 2 years. Thirty patients in the transplantation group received allogeneic hematopoietic stem cell transplantation (allo-HSCT) after 2-3 courses of consolidation with the original induction regimen. The median follow-up was 18 (3-96) months, and the main follow-up indicators were overall survival (OS) and disease free survival (DFS). Prognostic factors of adult ALL patients and treatment-related deaths in each group were analyzed.Results:The 3-year OS rates of the standard group, intensive group and transplantation group were 54.0% (95% CI: 35.3%-72.6%), 71.8% (95% CI: 41.0%-94.5%), 62.3% (95% CI: 43.6%-80.9%), with a statistically significant difference ( χ2=6.110, P=0.047). The 3-year DFS rates of the three groups were 31.4% (95% CI: 12.9%-49.8%), 72.1% (95% CI: 52.3%-91.9%), 65.7% (95% CI: 45.3%-86.1%), with a statistically significant difference ( χ2=13.831, P=0.001). There were no significant differences in OS and DFS between the intensive group and the transplantation group ( χ2=0.709, P=0.400; χ2=0.046, P=0.830). OS and DFS of the intensive group were better than those of the standard group ( χ2=5.346, P=0.021; χ2=10.326, P=0.010). Multivariate analysis suggested that bone marrow minimal residual disease (MRD) negative on day 14-21 of chemotherapy was an independent prognostic factor affecting adult ALL ( HR=0.114, 95% CI: 0.015-0.841, P=0.033). The 3-year OS rates of Ph + ALL patients who received and did not receive allo-HSCT were 53.5% (95% CI: 23.1%-83.8%), 52.4% (95% CI: 23.8%-81.0%), the 3-year DFS rates were 77.1% (95% CI: 54.2%-100.0%), 35.0% (95% CI: 4.8%-65.2%), and there were no significant differences between the two groups ( χ2=3.600, P=0.223; χ2=3.824, P=0.050). The treatment-related mortalities of the non-transplantation group (standard group + intensive group) and the transplantation group were 3.2% (2/63) and 20.0% (6/30), and the treatment-related mortality of the non-transplantation group was significantly lower than that of the transplantation group ( χ2=7.318, P=0.007). Conclusion:Adult ALL has a poor prognosis. The 3-year OS rate and 3-year DFS rate of BFM intensive consolidation therapy are better than those of standard consolidation therapy, achieving a similar effect to allo-HSCT, but treatment-related mortality does not increase significantly. Patients with bone marrow MRD negative on the day 14-21 of chemotherapy have the better OS and DFS.

ABSTRACT

Objective:To explore the effect of PRECEDE-PROCEED model on health behavior and quality of life of patients after total hip arthroplasty. Methods:From February to December, 2018, 103 patients who underwent primary total hip arthroplasty were divided into control group (n = 51) and intervention group (n = 52). The control group received routine perioperative guidance, while the intervention group received PRECEDE-PROCEED model in addition, in accordance to the nine links of the model, multi-dimensional intervention measures should be formulated with tendency factors, contributing factors and strengthening factors as the core. They were followed up for six months after discharge, and were assessed with Health Promoting Life style Profile II (HPLP II) and the MOS Item Short From Health Survey (SF-36) one, three and six months after discharge, respectively. Results:There was no significant difference in the scores of HPLP II and SF-36 between two groups at discharge (P > 0.05). The scores of HPLP II and SF-36 were higher than in the intervention group than in the control group one, three and six months after discharge (t > 2.307, P < 0.05). Conclusion:PRECEDE- PROCEED model could change the undesirable life behavior after operation, and improve the health behavior and quality of life of patients with total hip arthroplasty.

ABSTRACT

OBJECTIVE@#To analyze the relationship between cytogenetic changes and the progression in the patients with chronic myeloid leukemia (CML) during the treatment with tyrosine kinase inhibitor (TKI).@*METHODS@#The chromosome G banding of 150 patients with CML treated in our hospital, was carried out to analyze the karyotype by the 24 h short-term culture or direct method of bone marrow cells, and the point mutation of the ABL kinase area was detected, the relationship between cytogenetic changes and the evolution of the disease course was analyzed.@*RESULTS@#The indirect fluorescence in situ hybridization showed that the BCR-ABL fusion gene of 150 patients was positive, out of which 142 cases showed positive Philadelphia (Ph) (94.67%), 8 cases with Ph negative (5.33%). Among 142 cases with Ph positive on the first diagnosis, and 14 cases (9.86%) with additional chromosome abnormality (9.86%), 4 cases (2.82%) with mutation translocation with 124 cases (87.32%), standard translocation t (9; 22) (q34; Q11) were found. Out of the 14 patients with additional chromosomal abnormalities, 8 cases with "main pathmay" abnormalities, 2 case with -Y abnormalities, and 4 cases with "secondary pathway" abnormalities were observed. During TKI treatment, additional chromosomal abnormalities were found in 46 patients with standard translocation and abnormal number of chromosomes, and the incidence of disease progression and point mutation were higher (P<0.05). Compared with patients with the standard translocation, the disease-free survival rate of the patients diagnosed as CML at 1st visit and with additional chromosome abnormality was significantly decreased (P<0.05), but the overall survival rate showed no significantly different (P>0.05). Compared with patients without additional cvtogenetic aberrations, the disease free and overall survival rate of the patients with additional cytogenetic aberrations during the TKI treatment of CML in chronic phase were significantly decreased (P<0.05).@*CONCLUSION@#Some CML patients may have additional chromosomal abnormalities during the onset and development of the disease, and these patients are at higher risk of disease progression.

ABSTRACT

Objective@#To investigate the relationship between systemic inflammatory markers such as neutrophil/lymphocyte ratio (NLR) and C-reactive protein/albumin ratio (CAR), and lymph node metastasis in patients with cN0 gastric cancer. To establish a nomogram model to predict the risk of lymph node metastasis in patients with cN0 gastric cancer.@*Methods@#The preoperative systemic inflammatory markers and clinical data of 134 patients with cN0 gastric cancer were retrospectively analyzed, and these markers of patients with negative (pN0) or positive (pN+ ) lymph node metastasis in postoperative pathological diagnosis were compared. The receiver operating characteristic (ROC) curve was used to evaluate the predictive effect of preoperative systemic inflammatory markers on lymph node metastasis. The influencing factors for lymph node metastasis were assessed by univariate analysis and multivariate logistic regression analysis. A nomogram subsequently established by R software was validated by Bootstrap resampling as internal validation.@*Results@#Compared with pN0 group, NE (P=0.022), CRP (P<0.001), NLR (P<0.001), PLR (P=0.003) and CAR (P<0.001) were higher, LY (P=0.003) and Alb (P=0.042) were lower in pN+ group. ROC curve analysis showed that the area under the curve (AUC) of postoperative pathological lymph node metastasis in patients with cN0 gastric cancer diagnosed by NLR, PLR and CAR were 0.687, 0.651 and 0.694, respectively, and the best cutoff values were 2.12, 113.59 and 0.02, respectively. The corresponding sensitivity and specificity were 62.9% and 72.2%, 77.4% and 48.6%, 74.2% and 58.3%, respectively. Univariate analysis showed that tumor size, depth of invasion, NLR, PLR and CAR were associated with lymph node metastasis in cN0 gastric cancer patients (all P<0.05). Multivariate analysis showed that depth of invasion, NLR and CAR were independent influencing factors of lymph node metastasis in patients with cN0 gastric cancer. OR were 8.084, 3.540 and 3.092, respectively (all P<0.05). The C-index of the nomogram model was 0.847 (95% CI: 0.782-0.915). The predicting calibration curve was properly fit with the ideal curve in calibration chart.@*Conclusion@#Combination of NLR and CAR to establish a nomogram model has a good consistency and can accurately predict the risk of lymph node metastasis in patients with cN0 gastric cancer.

ABSTRACT

Objective To comparatively analyze the acute adverse reactions of helical tomotherapy ( HT) and intensity-modulated radiation therapy ( IMRT) for nasopharyngeal carcinoma ( NPC) . Methods A total of 100 NPC patients treated with radiotherapy were selected and divided into the HT group ( n=50) and IMRT group ( n=50) . All patients were treated with concurrent chemoradiotherapy. The prescription dose of radiotherapy was DT 68.2-73.8 Gy/30-34F. The severity of acute adverse reactions of skin, oral mucosa, salivary glands and esophagus was evaluated with the established RTOG criteria. The differences between two groups were evaluated by paired t-test. Results The dose of organs at risk ( OARs) in the HT group was significantly lower than that in the IMRT group ( P<0.05) , whereas the dose of target area of PTVnx, PTVnd ( left) and PTVnd ( right) did not significantly differ between two groups ( all P>0.05) . In the HT group, the incidence rate of grade 0-3 acute adverse reactions in the skin, oral mucosa, salivary glands and esophagus were ( 14%, 68%, 18%, 0%) , ( 10%, 54%, 36%, 0%) , ( 0%, 74%, 26%, 0%) and ( 10%, 60%, 28%, 2%) , respectively. In the IMRT group, the corresponding results were ( 0%, 52%, 48%, 0%) , ( 0%, 58%, 42%, 0%) , ( 0%, 28%, 72%, 0%) and ( 0, 40%, 60%, 0%) , respectively. The severity of acute adverse reactions of skin, salivary glands and esophagus in the HT group was slighter than those in the IMRT group ( all P<0.05) , the acute adverse reactions in the oral mucosa were similar between two groups ( P>0.05) . In the HT group, the onset time of acute adverse reactions in the skin was later than that in the IMRT group ( P<0.05) , and the onset time of other adverse reactions was similar between two groups ( all P>0.05) . Conclusions Both HT and IMRT can meet the requirements of the dose distribution in the target area for NPC, whereas HT is superior to IMRT in terms of the protection of OARs protection, the severity and onset time of acute adverse reactions.

ABSTRACT

To investigate the " drug-guide" effect of Achyranthes bidentata saponins( ABS) and geniposide( GE) in the treatment on adjuvant arthritis( AA) rats. A UHPLC-MS/MS method for the quantitative determination of GE,zingibroside R1,ginsenoside Ro and chikusetsu saponin Ⅳa in rat blood and joint dialysate was established. After single or combined administration with ABS and GE was given to AA rat model,a microdialysis sampling method for rat joint cavity and jugular vein blood vessels was established to collect microdialysis samples. Waters Acquity HSS C_(18) column was used to separate the above four components,with mobile phase as acetonitrile-0. 1% formic acid water as mobile phase for gradient elution. ESI source was adopted for mass spectra in a negative ion scanning mode. Multiple reaction monitoring( MRM) mode was applied to detect the above four components. The methodological results showed that GE,zingibroside R1,ginsenoside Ro and chikusetsu saponin Ⅳa demonstrated a good linear relationship within the concentration ranges of 2-4 000,16-4 096,14-3 584,23-5 888 μg·L-1 respectively. The precision,accuracy,stability and matrix effect of these four ingredients reached the requirements of quantitative analysis of biological samples. The pharmacokinetic results demonstrated that the combined administration of ABS and GE( 60 mg·kg~(-1)+60 mg·kg~(-1)) can increase the degree of GE in joint cavity distribution,and the AUCjoint/AUCplasmwere twice of that of single administration of GE( 60 mg·kg~(-1)),which indicated that ABS might played a vital role in GE's distribution to joint cavity. Moreover,there was no significant difference between the distribution trend of total three ABS and GE in rats. The pharmacodynamics results showed that the combined administration of ABS and GE has stronger effects on paw swelling,arthritis index and synovial pathomorphology of AA rats than single administration of GE,which suggested that ABS might improve GE's anti-inflammatory effect in AA rats. Based on the above results,ABS has a targeting effect in increasing GE's concentration in joint cavity,with a synergy in efficacy.

ABSTRACT

Objective@#To analyze the phenotype and genotype of a Chinese pedigree with inherited dysfibrinogenaemia and investigate the molecular mechanism of the disease. @*Methods@#Venous blood samples were collected from all family members, and routine coagulation tests were conducted. Functional fibrinogen in venous blood samples was measured by Clauss method, and the antigen level of fibrinogen in plasma was measured by immunoturbidimetry assay. All the exons and exon-intron boundaries of the three fibrinogen genes were analyzed by direct sequencing. Fibrinogen electrophoresis, fibrinogen clottability measurement, fibrin polymerisation measurement and electron microscopy scanning were also used to investigate the molecular characteristics and pathogenesis. @*Results@#The proband had normal activated partial thromboplastin time, prothrombin time and plasma fibrinogen antigen, but prolonged thrombin time, prolonged reptilase time and reduced fibrinogen activity level, which were also found in his father. The sequencing results of the proband revealed heterozygous A1211G in the exon 2 of FGA gene originating from his father, which caused Arg19Gly missense mutation. The western-blot results showed that no abnormal bands of plasma fibrinogen were found in the proband and his father. Both thrombin-induced fibrin polymerisation and reptilase induced fibrin polymerisation were significantly impaired compared to normal control. Fibrinogen clottability measurement showed that only about 20.8% molecules of plasma fibrinogen in the proband were involved in the clot formation. Scanning electron microscopy revealed that the proband′s average fibre diameters were found to be significantly thicker than that of the control(P<0.001), and the density was smaller than that of normal control. @*Conclusion@#The Arg19Gly mutation should be responsible for the proband′s dysfibrinogenaemia and the relevant clinical symptoms.

ABSTRACT

Objective@#To observe the effect of action observation combined with occupational therapy on the upper limb function and ability in the activities of daily living after a stroke.@*Methods@#Forty-two stroke survivors were randomly divided into a treatment group and a control group, each of 21. Both groups were given conventional rehabilitation training and conventional occupational therapy. The treatment group additionally performed action observation. The Fugl-Meyer assessment (FMA-UE), a Hong Kong version of the functional test for the hemiplegic upper extremity (FTHUE-HK) and the Modified Barthel index (MBI) were used for assessment before and after 8 weeks of treatment.@*Results@#Before the treatment there were no significant differences between the two groups. Afterward, significant improvement was observed in all of the measurements in both groups. Compared with the control group, the treatment group showed more significant improvement in its average FMA-UE, FTHUE-HK and MBI scores.@*Conclusion@#Action observation can improve the effects of rehabilitation and occupational therapy after stroke.

ABSTRACT

BACKGROUND: Benzalkonium chloride has been used in dental restorative materials to enhance the long-lasting antibacterial properties of materials. OBJECTIVE: To evaluate the antibacterial activity of benzalkonium chloride on oral common pathogenic bacteria in vitro. METHODS: The agar diffusion method was used to determine the inhibitory effects of antibacterial agents, 0.1% benzalkonium chloride, 3% H2O2and 5.25% sodium hypochlorite, on five kind of oral pathogens, Porphyromonas gingivalis (P.g), Prevotella intermedia (P.i), Actinobacillus actionmycemcomitans (A.a), Streptococcus mutans (S.m) and Enterococcus faecalis (E.f). The tube dilution method was used to detect the minimal inhibitory concentration of benzalkonium chloride against the five bacteria mentioned above. RESULTS AND CONCLUSION: The antibacterial effect of 0.1% benzalkonium chloride on P.g was not significantly different from that of 3% hydrogen peroxide (P>0.05), while 0.1% benzalkonium chloride showed better effect on P.i than 3% hydrogen peroxide (P<0.05). On P.g and P.i, the antibacterial effect of 0.1% benzalkonium chloride was worse than that of 5.25% sodium hypochloritethe ( P<0.05). The antibacterial effect of 0.1% benzalkonium chloride on A.a and S.m was better than that of 3% hydrogen peroxide (P<0.05), and similar to that of 5.25% sodium hypochlorite (P>0.05). The antibacterial effect of 0.1% benzalkonium chloride on E.f was better than that of 3% hydrogen peroxide (P < 0.05), but worse than that of 5.25% sodium hypochlorite (P < 0.05). The minimal inhibitory concentration of benzalkonium chloride to P.g, P.i, A.a, S.m, E.f was 16, 2, 4, 2, 4 mg/L, respectively. To conclude, 0.1% benzalkonium chloride has strong antibacterial effects on P.g, P.i, A.a, S.m and E.f.
