ABSTRACT
Objective: To investigate the effects of buccal acupuncture on analgesia, immune indicators, and expression levels of Survivin and Livin proteins in patients with advanced-stage primary liver cancer. Methods: Eighty patients with advanced-stage primary liver cancer were selected and divided into control and treatment groups according to the difference in treatment modalities, with 40 patients in each group. The control group received transcatheter arterial chemoembolization (TACE), and the treatment group received buccal acupuncture in addition to TACE. The recent efficacy, analgesic effect, liver function, serum tumor markers, Survivin and Livin protein expression levels in liver cancer tissue, and immune indexes were analyzed and compared between the two groups. Results: The objective response rate (ORR) and disease control rate (DCR) of the treatment group were 37.5% and 77.5%, respectively, which were significantly higher than those of the control group (22.5% and 52.5%), and the recent efficacy of the treatment group was significantly better than that of the control group (P<0.05). The onset of analgesia in the treatment group was significantly faster than that in the control group (P<0.05), the duration of analgesia was significantly longer than that in the control group (P<0.05), and the numeric rating scale (NRS) score of pain after treatment was significantly lower than that in the control group (P<0.05). In the treatment group, the aspartate aminotransferase (AST), alanine aminotransferase (ALT), and albumin/globulin (A/G) were significantly lower than those in the control group (P<0.05), and the serum levels of alpha-fetoprotein (AFP), alpha-L-fucosidase (AFU), and carcinoembryonic antigen (CEA) were significantly lower than those in the control group (P<0.05), and the expression levels of Survivin and Livin in liver cancer tissue were significantly lower than those in the control group (P<0.05); CD4+ and CD4+/CD8+ in the treatment group were significantly higher than those in the control group, and CD8+ was significantly lower than that in the control group after treatment (P<0.05). Conclusion: Buccal acupuncture can reduce the degree of pain and liver function damage in patients with advanced- stage primary liver cancer and lower the serum tumor marker levels, and its mechanism of action may be related to the down-regulation of Survivin and Livin protein expression levels in the liver cancer tissue and the regulation of the immune function.
ABSTRACT
Objective:This study has investigated the value of detecting cerebrospinal fluid (CSF) MyD88L265P mutation and interleukin-10 (IL-10) levels in the prognosis of PCNSL.Methods:We retrospectively analyzed the clinical data, CSF characteristics (including cytology, cell counting, total protein, and the level of cytokine IL-10) and treatment process of 39 PCNSL patients newly diagnosed by surgery and pathology (18 males and 21 females, aged 40-73 years) from August 2013 to December 2016 in Hua Shan Hospital North. MyD88L265P mutation was detected by digital PCR in 39 paraffin-embedded tissues and 35 cerebrospinal fluid samples. Log-rank test was used for univariate analysis and Cox regression for multivariate analysis to establish the prognosis model of PCNSL which might be related to PCNSL first progress-free survival (PFS) and overall survival (OS).Results:The median age of the 39 PCNSL patients was 59 years old, with 30.8% (12/39) intraocular involvement. The mutation rate of MyD88L265P in tissues and cerebrospinal fluid was 74.4% (29/39) and 40.0% (14/35), respectively. 51.9% (14/27) patients were observed with MyD88L265P mutation in both tissues and CFS. Univariate analysis showed that intraocular involvement, high level of IL-10 in CFS (≥45 pg/ml), and MyD88L265P mutation in CFS are factors significantly influencing median progression-free survival (mPFS) of patients ( P<0.05). Patients with intraocular involvement had shorter OS than those without involvement which was statistically significant ( HR=6.5,95% CI 1.7-47.3, P<0.05). And multivariate analysis showed that intraocular involvement ( HR=2.4, 95% CI 1.3-7.8, P<0.05) and CFS MyD88L265P mutation ( HR=2.1, 95% CI 1.1-5.7, P<0.05) were independent prognostic factors for PFS. Conclusion:The presence of intraocular involvement and MyD88L265P mutation in CFS indicated poor prognosis of PCNSL patients. High CSF IL-10 level was not an independent factor affecting prognosis.
ABSTRACT
Objective To investigate the effect of repetitive transcranial magnetic stimulation (rTMS) on the negative symptoms of chronic schizophrenia and on the P300 component of schizophrenics' event-related potentials (ERPs).Methods Ninety convalescing schizophrenia patients were randomly divided into a 5 Hz group,a 10 Hz group and a 15 Hz group,each of 30.The three groups were treated with the corresponding 5 Hz,10 Hz or 15 Hz rTMS once a day,five times a week for five consecutive weeks.The P300 ERPs of all three groups were tested before and after the treatment.Any curative effect was evaluated using the scale for the assessment of negative symptoms (SANS).Results After the treatment,the average SANS score of the 10 Hz group was significantly different from that before the treatment and also from those of the other two groups after the treatment.After the treatment,significant improvement was also observed in the amplitude of P300 in the 10 Hz group.The treatment's effectiveness was negatively correlated with age and longer course of the disease.Conelusion rTMS at 10 Hz is the most effective of the protocols tested for improving the negative symptoms of schizophrenia and improving cognitive functioning.
ABSTRACT
Objective To investigate the expressions of BAP1 and TET2 proteins in bone marrow of patients with chronic myelomonocytic leukemia (CMML) and their relationship with the prognosis of CMML. Methods The bone marrow paraffin specimens of 41 cases from 41 adult CMML patients diagnosed by Shanghai Sino-US Joint Leukemia Coordination Group from September 2003 to May 2007 were collected. The immunohistochemistry was used to detect the expressions of BAP1 and TET2 proteins in 41 CMML patients. The expressions of TET2 and BAP1 proteins were also detected by the same method in 40 adult patients with acute myelomonocytic leukemia (AMML) and 20 patients with iron deficiency anemia (IDA) diagnosed at the same time as the comparison. The clinical data of 41 CMML patients were analyzed by using retrospective cohort study. The count data were compared by using chi-square test. The correlation between expressions of BAP1 and TET2 proteins was analyzed by using Pearson correlation analysis. Kaplan-Meier method was used to calculate the survival time, and Log-rank test was used for single factor analysis. Results In 41 CMML patients, the positive expression rate of BAP1 was 31.7% (13/41), including 28.6% (8/28) in CMML-1 patients and 38.5% (5/13) in CMML-2 patients; the positive expression rate of TET2 was 41.5% (17/41), including 39.3% (11/28) in CMML-1 patients and 46.2% (6/13) in CMML-2 patients. In 40 AMML patients, the positive expression rate of BAP1 was 32.5% (13/40), and the positive expression rate of TET2 was 35.0% (14/40). In 20 IDA patients, the positive expression rate of BAP1 was 5.0% (1/20), and TET2 had no positive expression. There was no significant difference in the expressions of BAP1 and TET2 proteins between CMML-1 and CMML-2 patients (χ 2 = 0.40, P = 0.53; χ 2 = 0.17, P = 0.68). There was no significant difference in the expressions of BAP1 and TET2 proteins between CMML and AMML patients (χ 2 = 0.01, P = 0.94; χ 2 = 0.36, P = 0.64). There were significant differences in the positive expression rate of BAP1 and TET2 proteins between hematological neoplastic disease (CMML+AMML) and hematological non-neoplastic disease (IDA) (χ 2 = 6.01, P < 0.05; χ 2 = 11.04, P < 0.01). Pearson correlation analysis showed that there was no correlation between expressions of BAP1 and TET2 proteins (r = 0.35, P = 0.27). Univariate analysis showed that anemia (Hb < 60 g/L), mature monocyte count ≥ 2.0×109/L, neutrophil count (1.5×109/L), abnormal karyotype were associated with poor prognosis for CMML. Protein expressions of BAP1 and TET2 were not related with the prognosis of CMML (χ 2 = 0.28, P = 0.600; χ 2 = 0.53, P = 0.460). Conclusion Both BAP1 and TET2 proteins have high positive expression rates in CMML patients, but the expressions of them are not related to the prognosis.
ABSTRACT
Cancer stem cells are considered to be the origin of tumor relapse.Isolating and identifying them by special immune-phenotypes is the most commonly used method.The technique of isolating SP cells is very mature.More attentions are being paid to the isolation of cancer stem cells using differential expression activities of Wnt pathway on surface of tumor cells.Establishing stem cells niches to capture cancer tumor cells remains to be further evaluated.
ABSTRACT
Objective To study the effects caused by novel antipsychotics quetiapine and aripiprazole on concentrations of platelet 5-HT in patients with schizophrenia,and to explore the relationships among the change of platelet 5-HT concentrations, psychiatric symptoms and the sensitivity of therapy. Methods Sixty-eight patients with schizophrenia meeting International Classification of Diseases-10 (ICD-10) were enrolled in the study. They were divided into quetiapine group(n=34) and aripiprazole group(n=34) according to the sequence of admis-sion. The platelet 5-HT concentrations were measured with high performance liquid chromatography method(HPLC-ECD). The positive and negative syndrome scale (PANSS) was used to evaluate the psychopathology. Treatment emergent symptom scale (TESS) was used to evaluate the side effects. PANSS,TESS were used at pre-treatment,the end of 4th and 8th week of treatment. Results The platelet 5-HT concentrations in two groups were higher af-ter 8 weeks treatment,but had no statistically significant difference (P>0.05). In quetiapine group, the platelet 5-HT concentration was (458.89±233.36) ng/10~9 at the pre-treatment, and (554.31±313.22) ng/10~9 at the end of treatment (t=1.709, P=0.099). In aripiprazole group, the platelet 5-HT concentration was (409.83±149.32)ng/10~9 at the pretreatment, and (421.27±245.96)ng/10~9 at the end of treatment (t=0.321, P=0.819). There was no difference between two groups(P>0.05). Stepwise regression analysis showed the changing rate of platelet 5-HT concentrations was positively correlated with the dosage of quetiapine (r=0.385, P=0.039).It was positively correlated with the decreasing rate of PANSS in aripiprazole group(r=0.391, P=0.040). Con-dusion The changes of psychiatric symptoms and the dosages of antipsychotics maybe have intimate relationships with platelet 5-HT concentrations in the course of medication.
