OBJECTIVETo observe the differences of therapeutic effect of spastic paralysis after stroke between electroacupuncture and acupuncture and explore the mechanism.

METHODSSixty-four cases were randomly divided into an electroacupuncture group (n = 33) and an acupuncture group (n = 31). Both groups were treated with Bobath facilitation techniques and medicine treatments. Quchi (LI 11), Hegu (LI 4), Yanglingquan (GB 34), Sanyinjiao (SP 6), et al. on the affected side were selected in each group. The needle was retained for 30 min, and the manipulation was applied for 1 min in the acupuncture group, and electroacupuncture was added in the electroacupuncture group. Stroke Impairment Assessment Set (SIAS) was adopted to assess the whole function status after sroke, and the contents of glutamate (Glu) and gamma-aminobutyric acid (GABA) in serum and clinical efficacy were observed in the two groups.

RESULTSThe SIAS score increased after treatment as compared with that before treatment in either group (both P < 0.01), and the electroacupuncture group was superior to the acupuncture group (P < 0.01); the content of Glu in blood serum and ratio of Glu/GABA reduced, while the content of GABA in serum increased after treatment as compared with those before treatment in either group (all P < 0.01), but the improvement of above indices were much more apparently in the electroacupuncture group as compared with those in the acupuncture group (P < 0.01, P < 0.05); the total effective rate of 90.9% (30/33) in the electroacupuncture group was superior to that of 83.9% (26/31) in the acupuncture group (P < 0.05).

CONCLUSIONElectroacupuncture can improve therapeutic effect of spastic paralysis after stroke, it's mechanism may be ralated to ajusting the contents of Glu and GABA in serum.

OBJECTIVETo study the effects of ApoE gene polymorphism on anti-inflammatory action of Xuezhikang Capsule.

METHODSOne hundred and two patients with hyperlipidemia (as the treated group) and one hundred healthy volunteers (as the control group) were enrolled in the case-control study. Total DNA of the peripheral blood was extracted and ApoE genotypes were determined by PCR sequence analysis. The serum levels of tumor necrosis factor alpha (TNF-alpha), interleukin 6 (IL-6), and high sensitivity C reactive protein (hs-CRP)were measured in all subjects. The changes of TNF-alpha, IL-6, and hs-CRP were detected before and after 6-week Xuezhikang Capsule treatment, thus analyzing the correlation between ApoE gene polymorphism and changes of each inflammatory factor.

RESULTSThe frequency of E3/3 genotype was 86% (86/100 cases)in the control group, significantly higher than that of the treated group (62.7%, 64/102 cases). The frequency of E3/4 genotype was 6% (6/100 cases) in the control group, significantly lower than that of the treated group (21.6%, 22/102 cases; both P < 0.05). Compared with the control group, the serum levels of TNF-alpha, IL-6, and hs-CPR were higher in the treated group before treatment (P < 0.05). In hyperlipidemia patients with E3/4 + E4/4 genotype, the serum level of TNF-alpha was higher than that of E3/3 genotype (P < 0.05); the serum level of IL-6 was higher than that of E2/E2 + E2/E3 genotype (P < 0.05); the serum level of hs-CRP was higher than that of E2/E2 + E2/E3 and E3/E3 genotype (P < 0.05). But there was no statistical difference in the serum levels of TNF-alpha, IL-6, or hs-CPR between E3/3 and E2/E2 + E2/E3 genotype. After 6-week intervention of Xuezhikang Capsule, the serum levels of TNF-alpha, IL-6, and hs-CRP were lower in the treated group (P < 0.05), but the serum levels of TNF-alpha and IL-6 were still higher than those of the control group (P < 0.05). But there was no statistical difference in the decrement of TNF-alpha, IL-6, or hsCRP among E2/E2 + E2/E3, E3/E3, or E3/4 + E4/4 genotypes (P > 0.05).

CONCLUSIONSThe distribution of ApoE gene polymorphism is different between the hyperlipidemia patients and the healthy people. Chronic inflammatory reactions exist in hyperlipidemia patients, especially in those with e4 allele. Xuezhikang Capsule showed anti-inflammatory effects, but ApoE gene polymorphism did not affect its effects.

OBJECTIVETo study the correlation between Apo E gene polymorphism and patients with coronary heart disease (CHD) of phlegm-stasis syndrome (PSS).

METHODS78 CHD patients were assigned to PSS (49 cases) and non-phlegm-stasis syndrome (NPSS). Polymorphisms of Apo E gene in 78 CHD patients and 100 healthy subjects were detected by complete DNA sequencing.

RESULTSFive gene types as E3/3, E4/4, E2/ 3, E2/4, and E3/4 were detected in the two groups. The frequencies of genotype E3/3 and epsilon 3 allele were significantly lower in CHD patients than in the healthy subjects (P<0.01). But the frequencies of genotype E3/4 and epsilon 4 allele were significantly higher in CHD patients than in the healthy subjects (P<0.01). In CHD patients, the frequencies of genotype E2/4 + E3/4 + E4/4 and epsilon 4 allele were higher in PSS than in NPSS.

CONCLUSIONSApo E epsilon 4 allele was a susceptible allele to CHD, which was closely correlated to CHD PSS. It was inferred that it might be one of main susceptible alleles for CHD PSS.

OBJECTIVETo study the mutation patterns of epithelial growth factor receptor (EGFR) exon 18, 19 and 21 in Chinese non-small-cell lung cancers (NSCLC).

METHODSSomatic mutation in samples of 32 cases without Iressa-treatment were compared with that in 10 volunteers blood control. The mutations were identified for the forward and reverse sequence chains for the tyrosine kinase domain of the EGFR gene, followed by DNA template abstraction and Touchdown PCR.

RESULTSNine types of mutation were found in sequences of 7 cases among the 32 non-small cell lung carcinoma tissues, namely, five reported mutation within exon 19, and two new heterozygous mutations, L833V and H835L within exon 21, and two intron polymorphism. These results showed a mutation rate of 9/32 (28.1%) in Chinese with NSCLC, and of 31.6% in lung adenocarcinomas.

CONCLUSIONEGFR mutation rate in Chinese with NSCLC is consistent with those of Asian women reported in the literature but new mutation points in Chinese were presented as L833V and H835L. The mutation rate is in concordance with release rate of NSCLC obtained by Gefitinib treatment in Chinese.

This study was aimed to investigate the relationship of immunophenotypic features with minimal residual disease (MRD) detection and gene types in APL patients. Immunophenotypes were analyzed in 221 newly diagnosed APL patients by using four-color flow cytometry. Among of them, CD123 antibody was examined in 87 patients and the fused gene pml-raralpha were detected by PCR in 196 specimens simultaneously. The results of immunophenotyping demonstrated that the positive percentages of CD123, CD33 and CD9 in newly diagnosed APL patients were 100%, 99.1% and 96.0% respectively, and mean percentages of positive cells in positive patients were all around 90%. Although the positive rates of CD117, CD13, CD38 and CD64 were all above 96%, but the mean percentages of positive cells in different positive patients were diverse and average percentages of positive cells were about 70%. CD15, CD56 and CD11b were expressed in some patients, but CD34 and HLA-DR were rarely expressed in the majority of patients, and average positive percentages were all lower. Among 196 newly diagnosed APL patients, bcr1, bcr2 and bcr3 expressions were 63.3%, 4.6% and 32.1% respectively. The results showed a strong correlation of positive expression of CD34 with bcr3 isoform. When cut-off value was chosen as 20%, the proportions of CD34 positive patients in bcr3 and bcr1 cases were 15.4% (10/65) and 3.3% (4/121) separately, which had a significant difference (p < 0.05). When cut-off value was 10%, bcr3 cases had a significantly higher percentage of CD34 positive, compared with bcr1 cases (p < 0.001), which was 47.7% (31/65) and 5.8% (7/121) respectively. However, there was no statistically significant difference on the other antigens between the two groups. Bcr3 isoform was highly indicated when CD34 was positive and non- large side scatter (NL-SSC) was shown in APL cells. It is concluded that there is a unique characteristics of immunophenotyping, and antigens such as CD123, CD33 and CD9 are more applicable to the detection of MRD in APL patients. The positive expression of CD34 and NL-SSC are associated with bcr3 isoform, and the relationship between gene type and antigen expression can be suggested more accurately when the cut-off value is chosen as 10%.

To evaluate the significance of FCM in minimal residual disease (MRD) detection, the immunophenotyping and leukemia-associated immunophenotypes (LAIP) of leukemia cells from 273 adult and 142 childhood patients with B lineage acute lymphoblastic leukemia (B-ALL) were detected by four to six antibody combinations of 4-color CD45/SSC gating multiparametric flow cytometry (FCM). The results showed that the B-ALL patients could be classified into 4 subtypes based on different expression CD34 and CD10: subtype I (CD34(+)/CD10(-)), subtype II (CD34(+)/CD10(+)), subtype III (CD34(-)/CD10(+)), subtype IV (CD34(-)/CD10(-)). The LAIP was observed in 100% and 92% patients of subtype I and subtype II, respectively, whereas only 79.2% in subtype III. The incidence of LAIP in total B-ALL cases was 90% by using the antibodies detected in this investigation. There was no significantce different for incidence of LAIP between adult and pediatric patients. LAIP was observed in 77.6% of patients by labeling only CD34/CD10/CD19/CD45 4-color antibody combination. It is concluded that in 90% of childhood and adult B-ALL patients LAIP can be found, which suits MRD detection by multiparameter flow cytometry.

OBJECTIVETo evaluate levels of common specific fusion transcripts M-bcr-abl, m-bcr-abl, TEL-AML1, AML1-ETO, PML-RAR alpha, CBF beta-MYH11 in untreated leukemia patients.

METHODSSpecific fusion transcript levels were detected by TaqMan-based real-time quantitative RT-PCR technique in a total of 208 samples, including 195 bone marrow samples from 50 M-bcr-abl(+) chronic phase-chronic myeloid leukemia (CML-CP), 10 M-bcr-abl(+) acute lymphoblastic leukemia (ALL), 19 m-bcr-abl(+) ALL, 11 TEL-AML1(+) ALL, 30 AML1-ETO(+) acute myeloid leukemia (AML), 58 PML-RAR alpha(+) acute promyelocytic leukemia (APL) and 17 CBF beta-MYH11(+) AML patients and 13 peripheral blood samples from 13 M-bcr-abl(+) CML-CP patients. abl was chosen as internal control gene. Fusion transcript level was calculated as fusion transcript copies/abl transcript copies in percentage.

RESULTSBone marrow and peripheral blood samples of CML-CP patients had similar M-bcr-abl fusion transcript levels (median 30% vs 35%, P > 0.05). M- and m-bcr-abl (median 64% vs 54%) levels were similar in ALL patients (P > 0.05), M-bcr-abl level was significantly higher in ALL than CML-CP patients(P < 0.001). Median TEL-AML1 level was 228% in ALL patients. Among AML patients, AML1-ETO level was significantly higher than CBF beta-MYH11 and PML-RAR alpha levels (median 388% vs 145%, 388% vs 47%, all P < 0.001), CBF beta-MYH11 level was significantly higher than PML-RAR alpha level (P < 0.001). Fusion transcript levels of L-, V- and S-type PML-RAR alpha were 45%, 44% and 55%, respectively. L-type was significantly lower than S-type (P = 0.04).

CONCLUSIONSFusion transcript levels in untreated leukemia patients were different and patient-to-patient variations did exist. Detection of fusion transcript levels in untreated leukemia patients not only provides baseline for minimal residual disease monitoring and treatment evaluation but also enable the comparison in inter-laboratory data.
