ABSTRACT
Objective:To investigate the clinical efficacy of psychotherapy combined with early comprehensive rehabilitation therapy in the treatment of acute cerebral infarction and the possible mechanism of action.Methods:Eighty-four patients with acute cerebral infarction who received treatment in Yuhang Fifth People's Hospital, China between June 2018 and February 2020 were included in this study. They were randomly divided into an observation group ( n = 44) and a control group ( n = 40). The control group was treated with conventional therapy. The observation group was subjected to early comprehensive rehabilitation therapy combined with psychotherapy based on conventional therapy. All patients were treated for 1 month. Clinical efficacy, the percentage of highly glycosylated type I transmembrane glycoprotein-positive cells and vascular endothelial growth factor receptor-2-positive cells (CD 34+KDR +) in monocytes, and serum level of stromal cell-derived factor-1α were compared between the observation and control groups. Results:After treatment, the scores of Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD) and National Institutes of Health Stroke Scale (NIHSS) were (16.4 ± 3.8) points, (17.9 ± 5.2) points, (3.56 ± 0.46) points, respectively, which were significantly lower than those in the control group [(23.4 ± 5.6) points, (23.7 ± 6.4) points, (5.39 ± 0.87) points, t = 7.896, 7.258, 6.935, all P < 0.05]. Barthel Index, Fugl-Meyer score, and Functional Independence Score in the observation group were (79.7 ± 20.8) points, (54.6 ± 17.2) points, (96.8 ± 8.5) points, respectively, which were significantly higher than those in the control group [(60.4 ± 17.6) points, (39.6 ± 14.8) points, (83.1 ± 9.7) points, t = 8.123, 7.251, 8.009, all P < 0.05]. After treatment, the percentage of CD34 +KDR + in monocytes and serum level of stromal cell-derived factor-1α in the observation group were (1.58 ± 0.19)% and (1.84 ± 0.11) μg/L, respectively, which were significantly higher than those in the control group [(0.73 ± 0.20)% and (1.34 ± 0.09) μg/L, t = 7.125, 6.983, both P < 0.05). Conclusion:Based on conventional treatment, psychotherapy combined with early rehabilitation treatment can improve the clinical efficacy in the treatment of acute cerebral infarction possibly through increasing the percentage of CD 34+KDR + in monocytes and the serum level of stromal cell-derived factor-1α.
ABSTRACT
Objective:After using proximal femoral nail antirotation (PFNA) fixation to treat femoral intertro-chanteric fractures (ITFs), closed negative pressure drainage systems are often used for drainage, but the clinical effect of this method is uncertain. A prospective randomized controlled trial study was conducted to analyze the negative effects of negative pressure drainage systems after PFNA fixation.Methods:Sixty patients with ITFs and underwent PFNA fixation were randomly divided into two groups. Patients in the drainage group were equipped with negative pressure drainage systems after PFNA fixation. At 4, 10, and 90 days after the surgery, the visual analog scale (VAS) score, analgesic dosage, thigh swelling width, wound and infection status, hemoglobin, hematocrit level, total blood loss and transfusion blood volume of the patients were recorded to evaluate the prognosis.Results:The total blood loss of the drainage group [(579.1±236.7) ml] was greater than that of the non-drainage group [(427.8±239.8) ml; P=0.01]. The transfusion blood volume of the drainage group [(443.3±176.3) ml] was greater than that of the non-drainage group [(307.8±155.4) ml; P=0.01]. Compared with the non-drainage group, the drainage group had a higher VAS score at 4 days after the surgery (2.3±0.6, P=0.02). There was no difference between the two groups in analgesic dosage, thigh swelling width, wound infection and hematoma, hospital stay and the total number of complications (all P>0.05). Conclusions:In the patients with ITFs treated with PFNA fixation, the transfusion blood volume and total blood loss of the patients in the drainage group are higher than those in the non-drainage group. In addition, drainage systems may not have short-term benefits for postoperative wound conditions.
ABSTRACT
OBJECTIVE: Dynamic monitoring of the concentration variation of IgM and IgG in patients with SARS-CoV-2 infections and exploring their diagnostic value for coronavirus disease-19 (COVID-19). METHODS: A total of 15 patients with SARS-CoV-2 infection were enrolled as the COVID-19 group, and 50 patients were enrolled as the control group. The concentrations of SARS-CoV-2-specific antibodies (IgM and IgG) were detected by a chemiluminescence immunoassay (CLIA). RESULTS: According to the cutoff value recommended by the manufacturer (cutoff = 10 AU/mL), the sensitivity, specificity, Youden index (YI), positive predictive value (PPV), and negative predictive value (NPV) of IgM were 60%, 100%, 60%, 100%, and 89.29%, respectively; and 86.67%, 100%, 86.67%, 100%, and 96.15%, respectively, for IgG. We reassessed the cutoff value of IgM. When the cutoff value for SARS-CoV-2 IgM was 1.83 AU/mL, the sensitivity, specificity, YI, PPV, and NPV were 93.33%, 98%, 91.33%, 93.33%, and 98%, respectively. During dynamic monitoring of the concentrations of IgM and IgG in COVID-19 patients, we found the shortest times before a patient became IgM and IgG seropositive after symptom onset were 1.5 and 2 days, respectively. The longest times were 7 and 8 days, respectively. The positive rates of SARS-CoV-2 IgM and IgG both reached 100% in 8-14 days after symptom onset. CONCLUSION: The IgM cutoff value of 1.83 AU/mL for the diagnosis of COVID-19 was much better than the cutoff suggested by the manufacturer. SARS-CoV-2 infection can be ruled out if antibodies against SARS-CoV-2 are still undetectable 14 days after symptom onset.

BACKGROUND:The self-renew and regeneration capacity of the injured spinal cord is thought to be limited. Accordingly, cel transplantation is one potential strategy for promoting functional recovery after spinal cord injury. OBJECTIVE:To explore the effects ofPTEN silencing on the biological properties of bone marrow mesenchymal stem cels, hoping to offer better seed cels for tissue engineering. METHODS:Bone marrow mesenchymal stem cels were transfected with specific siRNA-silencedPTEN gene using the liposome method, and then RT-PCR was used to detect the mRNA expression ofPTEN. Variation of biological properties ofPTEN-transfected cels were detected by the way of MTT assay, cel cycle analysis, and Transwel assay. RESULTS AND CONCLUSION:PTEN is expressed highly in bone marrow mesenchymal stem cels, which is successfuly interfered by siRNA.PTEN-silenced cels have stronger survival, proliferation and migration abilities, which become a kind of better seed cels for tissue engineering.
ABSTRACT
Objective To examine clusters of anti-nuclear antibodies (ANA) and their associations with clinical features in patients with systemic lupus erythematosus (SLE).Methods It was a retrospective study.113 SLE patients were reviewed from March 2010 to May 2012 in Department of Rheumatology,Jinhua Central Hospital.ANA and specific autoantibodies to 15 kinds of nuclear antigens were tested by indirect immunofluorescence assay (IIF) and line immunoassay (LIA) respectively.Hierarchical clustering method was performed to analyze specific clusters of ANA profiles in SLE.Chi-square tests were used to investigate relationship between antibody clusters and clinical features of SLE.Results The positive rate of LIA for ANA was 97.3%,consistent with IIF method,and the total accordance rate of the both methods was 98.2%.Thirteen kinds of antigen-specific antibodies were detected in SLE patients by LIA.Clustering analysis for these antibodies showed three specific clusters in SLE,Nuc/His/dsDNA cluster (C1),low-Ro/low-La cluster (C2),and Ro/Sm/RNP cluster (C3),accounting for 36.3%,24.8%,38.9% of the total cases respectively.There were significant difference of AST levels among three clusters [(32.62 ± 21.92)U/L,(25.56 ± 16.63) U/L,(50.41 ± 60.86) U/L respectively for C1,C2 and C3].High incidences of chronic cutaneous lupus,abnormal renal indicators and inflammatory synovitis were found in all three clusters.Besides,there were significant differences among three clusters for the incidences of chronic cutaneous lupus (39.0%,39.3%,63.6% respectively for C1,C2,C3) and leukopenia/lymphopenia (56.1%,25.0%,56.8% respectively for C1,C2,C3) (P < 0.05).Patients in Ro/Sm/RNP cluster showed higher incidences of lupus nephritis (43.2%/26.8% or 39.3%); patients in low-Ro/low-La cluster showed low risk of hypertension (7.1%/19.5% or 22.7%) ; patients in Nuc/His/dsDNA cluster showed high incidences of thrombocytopenia (41.5%/21.4% or 25.0%) and high risk of lung or upper respiratory tract infection (46.3%/28.6% or 29.5%),but low incidence of neurologic symptoms (0%/ 3.6% % or 11.4%).Conclusion Three characterized ANA clusters are identified in SLE patients in this pilot study.Different clusters are associated with certain clinical features and complications ofSLE.However,the correlations found in this study need to be investigated further in larger populations.
ABSTRACT
Biomaterials are commonly applied in regenerative therapy and tissue engineering in bone.Generally,nanoparticles interact distinctively with bone cells and tissue,depending on their com-position,size,and shape.Therefore,detailed analyses of nanoparticle effects on cellular functions have been performed to select the most suitable candidates for supporting bone regeneration.This review will highlight potential nanoparticle applications in bone.We found that mesenchymal stem cells (MSCs) display exceptional regenerative potential.The delivery of genetic material with nanoparticulate carriers offers the possibility of overcoming certain disadvantages of standard protein delivery approaches.Moreover,nanoparticles are already clinically applied in cancer treatment.Thus,corresponding efforts could lead to new therapeutic strategies to improve bone regeneration or to treat bone disorders.
ABSTRACT
Objective To evaluate significance of the quantification of bcr-abl mRNA in diagnosis and therapy of chronic myeloid leukemia (CML),essentiality significance for monitoring minimal residual disease. Methods Bcr-abl mRNA of 518 CML patients were detected using real-time PCR. Results Expression of bcr-abl mRNA was gradually increased among blastic phase (BP) (12.6 %),accelerated phase (AP) (25.4 %) and chronic phase (CP) (57.2 %) (P<0.05). Quantification of bcr-abl mRNA was cut down gradually after allotransplantation in the patients and becomes normal after treatment for 6 months. But quantification of bcr-abl mRNA inpatients treated with imatinib mesylate became normal after 12 months. Conclusion Real-time PCR was reliable and can be used for diagnosis,monitoring the treatment outcome,detecting the minimal residual disease,and predicting blast crisis.
ABSTRACT
Objective To investigate the novel V617F point mutation of JAK2 gene by real-time PGR in the patients with chronic myeloproliferative disease (CMPD) and evaluate its clinical significance. Methods Genomic DNA from bone marrow or peripheral blood mononuclear cells was extracted from 56 patients with CMPD, including 26 cases of polycythemia vera (PV), 24 cases of essential thrombocythemia (ET), 5 cases of chronic idiopathicmyelofibrosis (CIMF) and 1 case of high eosinophilic syndrome (HES). The exon 14 of JAK2 gene which harbourd V617F mutation were screened by real-time PGR. Results JAK2 V617F mutation was measured in 29 of the 56 patients with CMPD. The prevalence of mutation was 65.38 %(17/26) in PV,37.50 % in ET and 60.00 %(3/5) in CIMF. The proportion of mutation in PV, ET and CIMF are respectively 53.85 %(14/26), 29.17 %(7/24), 40.0 %(2/5) in heterozygotes and 11.54 %(3/26), 8.33 %(2/24), 20.00 %(1/5)in homozygotes. JAK2 mutation was negative in one patient with HES. JAK2 V617F allele burden in PV, ET and CIMF are respectively 2.14×102-1.5×107, 9.80×102-4.4×107 and 4.10×103-3.70×106 copies. Conclusion Real-time PCR is a useful tool for pre cisely assess the grade of mutant allele burden as well as to screen JAK2V617F mutation simultaneously, which is simple and convenient to carry out in clinical laboratories for diagnosis and further evaluations of minimal residual disease in CMPD patients.

ABSTRACT
Objective To explore the effect of adriamycin, bleomyein, vincristine and dacarbazinum (ABVD) chemotherapy scheme executed at day I and day 8 for primary Hodgkin's lymphomas (HL). Methods 62 patients with primary HL in stages Ⅱ-Ⅳ treated in our department from October 2005 to October 2006 were divided into group A and B at random with 31 patients in each group. The patients in group A received ABVD chemotherapy scheme executed at day 1 and day 8 for 6-8 cycles. The patients in group B received ABVD chemotherapy scheme executed at day 1 and day 15 for 6-8 cycles. The patients of the groups received radiotherapy by the same doctor after chemotherapy according to the patients condition and the radiotherapy regimens were not affected by the grouping. Results The complete remission rate (CR)in group A after chemotherapy was 90. 3% (28/31);the one-year and two-year disease free survival (DFS) rates were 87. 1% (27/31) and 80.0% (20/25)respectively. The CR rate in group B after chemotherapy was 83.9% (26/31);the one-year and two-year DFS rates were 80. 6% (25/31)and 72. 0% (18/25) respectively. The discrepancy of CR rates and the one-year and two-year DFS rates between the two groups was not significant (P>0.05). The incidences of therapeutic side effecte such as myocardial iscnemia grade Ⅲ-Ⅳ liver function impair-ment,pulmonary fibrosis and serious marrow inhibition between the two groups were not significant too (P > 0.05). Average chemotherapy period for the patients in group A was 159 days; it was 69 days shorter than that in group B. Conclusion The CR rate,1-year DFS rate and 2-year DFS rate of ABVD chemotherapy scheme executed at day 1 and 8 are similar to those of ABVD chemotherapy scheme executed at day Ⅰ and 15 for primary HL in stages Ⅱ-Ⅳ. The side-effects of chemoterapy between group A and B are similar too. The chemotherapy period in group A is shortened significantly.

ABSTRACT
The effects of metoclopramide( MCP ) on the physiologic properties of guinea pig papillary muscles and the hemodynamics in anesthetic dogs were studied. MCP decreased contractility, increased the epinephrine concentration inducing automaticity and shifted the voltage-time plot to the right. But the functional refractory period was prolonged. Furthermore, the contractility and automaticity of the right auricle were decreased. MCP 5 mg/kg iv increased cardiac index (CI), systolic blood pressure ( SBP ), diastolic blood pressure ( DBP ), left ventricular systolic pressure ( LVSP ), maximal rate of change of intraventricular pressure ( dP/dtmax ), and total peripheral resistance ( TPR ) while MCP 10mg/kg iv decreased SBP, DBP, LVSP, dP/dtmax and TPR except increase of CI.
