OBJECTIVETo evaluate the effect and safety of Chinese herbal medicine Lingdankang Composite (LDK) combined dendritic cell-cytokine induced killer cells (DC-CIK) in treating leukemia.

METHODSSubjects were selected from leukemia patients who achieved hematological complete remission (HCR) but not achieved molecular biological remission (MBR), or with minimal residual leukemia (MRL) positive. Twenty patients, 19 of acute leukemia and 1 of chronic myelocytic leukemia, were enrolled. DC and CIK from patient's peripheral blood monocyte were separated respectively by blood cell separator, then DC-CIK was obtained through respective culture followed with mixed cultivation of them, and was infused back to the patient self via intravenous injection. The back infusion of DC-CIK was performed once every 15-20 days for 4-6 times in total. Meantime, LDK was administered orally every day.

RESULTSIn the 20 patients treated, 4 case of HCR achieved MBR, the negatively reversed marker gene was AML1/ETO in 1 case, CBFbeta/MYH11 in 1, bcr/abl in 1, and the other 1 was IgH gene rearrangement; 3 patients with positive MRL were reversed to negative. The 3-year CR rate was 75% with a medium CR period of 25 months (10-37 months). Except transient fever and chill in 5 cases, no other remarkable adverse reaction happened during or after DC-CIK infusion.

CONCLUSIONThe combined treatment of LDK and autologous DC-CIK in treating patients with HCR shows an obvious effect of clearing MRL, it is the appropriate choice for curing leukemia of HCR, and is safety for intravenous infusion, so it has potential clinical prospect.

OBJECTIVETo observe the clinical effect of Dihuang Zhixue Capsule (DZC, a Chinese preparation for cooling blood and dispelling toxic substances) in the treatment of childhood refractory idiopathic thrombocytopenic purpura (RITP), with cyclosporin A (CsA) used as the control.

METHODSForty-one children of RITP were randomized into the treated group and the control group. The 21 patients in the treated group were orally given 2 to 3 DZC capsules each time, thrice a day and the 20 in the control group were given 3 mg/kg CsA per day, with 3 months as one therapeutic course. The therapeutic efficacy, platelet count and adverse reaction in the two groups were compared at the end of the course.

RESULTS(1) In the treated group, 1 (4.8%) patient was evaluated as cured, 3 (14.3%) as markedly effective, 5 (23.8%) as effective, 5 (23.8%) as improved, 7 (33.3%) as ineffective, with the total effective rate being 66.7%; while in the control group, the corresponding numbers were 0, 2 (10.0%), 2 (10.0%), 3 (15.0%), 13 (65.0%) and 35.0%, respectively, showing statistical significance in difference between the total effective rates of the two groups (xi(2)=4.11, P=0.0426). (2) As compared with the baseline, the platelet count increased in both groups after 2 months' treatment (P<0.05). After 3 months' treatment, the platelet count was higher in the treated group than in the control group (P<0.05). (3) The improvement of hemorrhage in the treated group after 8 weeks' treatment was better than that in the control group (P<0.05). (4) No apparent adverse reaction was observed in the treated group, while in the control group, hirsutism was shown in 15 cases; gingival hyperplasia in 10; digestive reaction in 5, liver function impairment in 5, hypertension in 2 and renal impairment in 2.

CONCLUSIONThe therapeutic efficacy of DZC is better than that of CsA, and DZC shows good compliance but brings no obvious adverse reaction.

Hepatitis E virus (HEV) sequences including four major genotypes representative strains available in GenBank were aligned with the DNAMAN software. The highly conserved internal region of ORF2 was then subjected to design primers and a probe. Furthermore, a 0.3 kb fragment of HEV ORF2 containing the amplification region was transcribed in vitro to synthese cRNA standard and a universal real-time TaqMan PCR assay was optimized and developed to detect and quantify main genotypes RNA of HEV. The specificity and reliability of the real-time RT-PCR was confirmed by testing genotype I HEV, genotype IV HEV and clinical samples. The detection limit of real-time RT-PCR was found 2.0 x 10(1) copies per reaction using in vitro transcribed cRNA. Compared with nested RT-PCR in diagnosis of HEV, the real-time RT-PCR developed was 10 to 100-fold more sensitive than the nested RT-PCR. The detection results from 54 clinical specimens indicated real-time RT-PCR was a rapid, sensitive and reproducible diagnostic method for HEV. This assay will be useful as an early and rapid diagnostic assay for HEV.

Objective To investigate the expression of N6 methyladenine(m6A)demethylase human fat mass and obesity-associated(FTO)protein in nasopharyngeal carcinoma(NPC),and the effect of over-expression of FTO on the proliferation of nasopharyngeal carcinoma in vitro and in vivo.Methods Immunohistochemistry method was used to detect the expression of FTO protein in nasopharyngeal carcinoma tissues and para-cancerous tissues;The dominant expression cell line of FTO was screened,the over-expression FTO cell line was constructed.The cell pro-liferation was examined by soft-agar method.A mouse tumor model was developed for measurement of tumor growth.ResultsThe expression of FTO in nasopharyngeal carcinoma tissues was lower than that in adjacent tissues.Low ex-pression of FTO promoted proliferation of NPC cells,while over-expression of FTO reversed this effect.Conclusions FTO inhibits proliferation of nasopharyngeal carcinoma and this result may provide an experimental technology in searching therapeutic targets of chemotherapy for nasopharyngeal carcinoma.

Moyamoya disease is a chronic progressive occlusive cerebrovascular disease characterized by progressive occlusion of the terminal internal carotid artery with formation of an abnormal vascular network at the skull base. The pathogenesis of the disease is not fully understood and is mainly thought to be associated with genetic factors, environmental factors and immune inflammatory response. The discovery of relevant biomarkers may provide hope for elucidation of pathogenesis of moyamoya disease and the early diagnosis and treatment of it. From the perspectives of coding gene, non-coding RNA and protein related to moyamoya disease, the possible molecular mechanisms involved in the occurrence and development of moyamoya disease are elaborated to further clarify their value as biomarkers of moyamoya disease.

ObjectiveTo analyze the distribution of traditional Chinese medicine （TCM） patterns as well as factors related to acute exacerbation in group E of chronic obstructive pulmonary disease （COPD）. MethodsThe general data of 161 COPD patients， including gender， age， body mass index （BMI）， disease course， smoking history， and past history， were collected. In terms of the four examinations of TCM， the differentiated patterns included phlegm-heat obstructing the lung， turbid phlegm obstructing the lung， phlegm stasis obstructing the lung， lung-spleen qi deficiency， and lung-kidney deficiency. The modified British Medical Research Council （mMRC） scale and COPD assessment test （CAT）， the pulmonary function indicators including forced expiratory volume in the first second （FEV1） and ratio of forced expiratory volume to forced vital capacity at second 1 （FEV1/FVC）， GOLD grade， and the patient's acute exacerbations in the previous year were recorded. Multivariate regression analysis was performed using logistic regression model to determine the relevant factors of patients in COPD group E. The distribution of acute exacerbations in different TCM symptom patients in group E was analyzed. ResultsThere were 80 patients （49.69%） in group E and 81 patients （50.31%） in non-group E. In group E， 23 （28.75%） patients had a history of two acute exacerbations， while 35 （43.75%） had three acute exacerbations， and 22 （27.5%） had more than three acute exacerbations. There were 13 （16.25%） cases of phlegm-heat obstructing the lung pattern， 6 （7.5%） cases of turbid phlegm obstructing the lung pattern， 8 （10%） cases of phlegm stasis obstructing the lung pattern， 22 cases （27.5%） of lung-spleen qi deficiency pattern， and 31 （38.75%） cases of lung-kidney deficiency pattern. There were significant differences in smoking history， disease course， TCM pattern， TCM syndrome score， mMRC score， and CAT score between groups （P＜0.05）. A total of 107 of the 161 patients completed pulmonary function tests， and the differences in FEV1， FEV1/FVC and GOLD grades between groups were statistically significant （P＜0.05）. Multivariate regression analysis showed that TCM pattern， TCM syndrome score and CAT score were statistically significant factors for COPD patients in group E （P＜0.05）. There were statistically significant differences in the number of acute exacerbations in different TCM patterns in group E （P＜0.05）. The patients with two acute exacerbations in the past year were mainly phlegm-heat obstructing the lung and lung-spleen qi deficiency patterns， while the three acute exacerbations were mainly seen in lung-spleen qi deficiency and lung-kidney deficiency patterns， and more than three exacerbations were more common with lung -kidney deficiency pattern. ConclusionsPatients in COPD group E were mainly the lung-spleen qi deficiency and lung-kidney deficiency patterns. Deficiency of healthy qi is the main reason for the increase in the number of acute exacerbations， and TCM patterns and CAT score were the main related factors.
