OBJECTIVETo observe the effect of Baichanting Compound (BC) on dopamine (DA) in striatum of Parkinson's disease (PD) mice, and to screen the optimal component proportion.
METHODSThe PD model was established in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) induced C57BL/6 mice. By using uniform design, they were intervened by three extracts of BC in different proportions [Acanthopanax senticosus extract (X1): white peony root extract (X2): Uncaria rhynchophylla extract (X3) = 30.00: 34.92: 82.50, 48.00: 19.98: 72.19, 18.00: 44.88: 61.88, 36.00: 29.94: 51.56, 54.00: 15.00: 41.25, 24.00: 39.90: 30.94, 42.00: 24.96: 20.63). Equal volume of 5% carboxymethylcellulose sodium was administered to mice in the model group and the normal group by gastrogavage. All medication was lasted for 20 successive days. The dopamine (DA) content was determined by ultra performance liquid chromatography tandem mass spectrometry (UPLC-MS). Except 10 in the normal group, 20 PD model mice were screened and divided into the model group and the BC group (with the optimal proportion) according to random digit table. BC extract in optimal proportion was administered to mice in the BC group by gastrogavage, while equal volume of 5% carboxymethylcellulose sodium was administered to mice in the model group and the normal group by gastrogavage. All medication was lasted for 20 successive days. Praxiology was observed in each group. DA content in striatum was also detected. Results Compared with the normal group, the DA content in striatum decreased significantly in the model group (P < 0.01), suggesting a successful PD modeling. Compared with the model group, the DA content in striatum increased significantly in 1 and 2 groups (P<0.05). According to results of quadratic polynomial stepwise regression statistics, the regression equation obtained was: Y = 0.265 + 0.026 X 2 - 0.056 X 3 + 0.334 x 10(-3) x X1 x X3 + 0.691 x 10(-3) X X3(2). X3 extract was the main factor influencing the effectiveness (P < 0.01). The optimal proportion of BC was predicted by the regression equation: X1 = 54.00 mg/(kg x d), X2 = 44.88 mg/(kg x d), the X3 = 82.50 mg/(kg x d). The pole climbing time was shortened, times of autonomic activities increased, DA content was elevated, all with statistical difference in BC groups (P < 0.01, P < 0.05).
CONCLUSIONBC could increase DA content in PD model mice with the optimal proportion as 54.00: 44.88: 82.50.

The purpose of this study was to investigate the efficacy of non-myeloablative allogeneic stem cell transplantation (allo-NST) and its related technologies in hematological malignancies. 26 patients with hematological malignancies (acute leukemia 10, chronic myeloid leukemia 14, multiple myeloma 2) received allo-NST following conditioning regimens with fludarabine/cyclophosphamide/ATG in 14 cases or busulfan or melphalan/cyclophosphamide/ATG in 12 cases prior to infusion of 2 or 3 collections of G-CSF (600 microg/d) or G-CSF (300 microg/d) plus GM-CSF (300 microg/d) mobilized blood stem cell on the fifth day. A combination of cyclosporine A (CsA) and methotrexate (MTX) was administered for GVHD prophylaxis. Patients were eligible for donor lymphocyte infusion (DLI) (or donor stem cell infusion (DSI)) given in graded increments according to the chimeric formation and clinical feature. Generally, the dose of the first infusion was 1 x 10(7)/kg in 4th week post-transplantation. The engraftment analyses included the detection of microsatellite short tandem repeats (STRs), bcr/abl fusion gene, Philadelphia chromosome, HLA-locus analysis, sex chromosome and ABO blood type or blood subtype. The results showed that out of 26 patients, 22 (84.62%) were engrafted, 18/22 were full donor chimerism (FDC) up to now. Acute GVHD occurred in 3/26 (11.54%), while chronic GVHD was diagnosed in 6 out of 26 (23.07%) patients. The incidence and degree of infection and hemorrhage were low and slight. It is concluded that NST is a safe and effective therapy for hematological malignancies, whereas related technologies such as adaptation selected, conditioning regimen and transplantation immunotherapy should be studied further.

OBJECTIVETo evaluate the efficacy of ropivacaine injection at the acupoints Hegu and Sanyinjiao for labor analgesia and its effects on cortisol level in parturients.
METHODSA total of 120 ASA class I-II nulliparous women undergoing spontaneous term labor (37 to 41 weeks of gestation) with a live, singleton fetus in the occiput anterior position and requiring labor analgesia with acupuncture were enrolled in this study. These women were randomized into study group and control group and received injections of 1 mL of 0.2% ropivacaine and normal saline, respectively, at each of the acupoints of bilateral Sanyinjiao and Hegu in the first stage of labor. The Visual Analogue Scale (VAS) before and at 30, 60 and 120 min after analgesia, the time of labor, delivery outcome and cortisol levels were compared between the two groups.
RESULTSThe VAS was significantly lower in the study group than in the control group (P<0.05). At 120 min after injections of ropivacaine or saline, serum cortisol level was significantly higher in the control group than in the study group (P<0.05). The rates of cesarean section and instrumental delivery and the time of labor were all similar between the two groups (P>0.05).
CONCLUSIONRopivacaine injection at Hegu and Sanyinjiao is effective for labor analgesia and does not prolong the process of labor or increase the rates of cesarean section or instrumental delivery.

Objective To study the relationship between the initial expression level of glucocorticoid receptor (GR) and the treatment outcome in children with acute lymphoblastic leukemia (ALL). And to evaluate if the initial expression level of GR could be the prognostic factor for children with ALL.Methods Anti-GR-antibody was used to measure the GR expression level in the bone marrow samples from 48 newly diagnosed children with ALL with flow cytometry. Also the GR expression levels in the patients at complete remission were mea-sured. Fifteen randonmized samples from ALL patients in continuous complete remission (CCR) were measured in this study. The GR expre-ssion levels of 30 blood samples from children in control group were monitored. Results The initial GR expression level had no association with the results after therapy. The GR expression level in CR and CCR had no statistic difference compared with that in control group.Conclusions It is not clear yet if the initial GR expression level could be the prognostic factor in children with ALL. Monitoring dynamic changes of the GR expression level in children with ALL seems to be of no remarkable significance.

In order to investigate the clinical efficacy of non-myeloablative allogeneic stem cell transplantation (allo-NST) and related technology in patients with hematologic malignancies, twenty-six cases of hematological malignancies (10 AL, 14 CML, 2 MM patients) received NST following conditioning regimens with fludara + cyclophosphamide + ATG (14 cases) and busulfan or melphalan + cyclophosphamide + ATG (12 cases), G-CSF (600 micro g/d) or G-CSF (300 micro g/d) + GM-CSF (300 micro g/d) were used for mobilizing peripheral blood stem cell. A combination of cyclosporine A (CsA) and methotrexate (MTX) was administered for GVHD prophylaxis. Patients will be eligible for donor lymphocyte infusion (DLI) or donor stem cell infusion (DSI) given in graded increments according to the chimeric formation and clinical reaction. Generally the dose of the first infusion was 1 x 10(7)/kg at 4th week post-transplantation. The engraftment analysis included the detection of microsatellite short tandem repeats (STRs), Bcr/Abl fusion gene, Philadelphia chromosome, HLA-locus analysis, sex chromosome and ABO blood type or blood subtype. The results showed that 22 patients (84.62%) were engrafted, among which 18 patients were full donor chimerism (FDC) up to now. Acute GVHD occurred in 3/26 cases (11.54%). Chronic GVHD was diagnosed in 6 of 26 (23.07%) evaluable patients. The incidence of infection and hemorrhage was low and slight. It is concluded that allo-NST is a safe and effective therapeutic method for hematologic malignancies, but the related technology such as selection of indication, conditioning regimen and transplantation immunotherapy should be studied further.

The MAPK signaling pathway can mediate a variety of cytokines to participate in the processes of inflammation, cancer, immune disorder, and neurodegenerative diseases, and it also plays an important role in the development and progression of hepatic echinococcosis. This article reviews the structure and regulation of the MAPK signaling pathway and elaborates on the role of the MAPK signaling pathway in hepatic echinococcosis. It is pointed out that the MAPK signaling pathway can activate both the cyst and the host in hepatic echinococcosis, participate in the development and progression of the disease, and exert an impact on its treatment. Drug therapy targeting the MAPK signaling pathway is expected to become a new strategy for the treatment of hepatic echinococcosis.
