Objective To learn the effects of control measures,the screening situation and the epidemic situation of Schistosomiasis in Yongsheng county of Lijiang city of Yunnan province,and to provide a scientific basis for developing control strategies.Methods Annual surveillance data of Schistosomiasis of Yongsheng county from 2002 to 2010 were collected and analyzed by material retrospective method.Schistosomiasis screening situation,infection rate of people and cattle as well as snails area was statistically analyzed.Infection rate of people was from the screening results by indirect hemagglutination(IHA),and pathogenic examination of the positives(1 ∶ 10)was carried out through collection of eggs with nylon bag and hatching the stool.Infection rate of cattle was from etiology examination results by plastic cup pipe jacking method.Results From 2002 to 2010,257679 individuals were screened and 26540 cases (10.30％) were seropositive; with stool examination,451 (1.72％) were identified positive of 26233 persons; 603 (0.71％) were found positive of 85658 oxen.All of the positive detection rate of IHA method,the feces-positive detection rate in the population and the prevalence rate of oxen showed a declining trend(x2 =3615.53,785.68,434.50,all P＜ 0.05).The snails area was gradually reduced,the rate of snails environmental area was decline from 23.82％ in 2004 to 1.98％ in 2010.Conclusions The endemic situation of Schistosomiasis in Yongsheng county is controlled in the past eight years,but remains epidemic,and we will continue to strengthen monitoring,in order to achieve the goal of blocking the spread of Schistosomiasis.

This paper is aim to investigate the pharmacokinetics and absolute bioavailability of neoline in Beagle dogs, and provide a theoretical basis for further study. Ethyl acetate was used for liquid-liquid extracting after 10% ammonia alkalizing. The method of UPLC-Q-TOF-MS was established for the determination of neoline plasma concentrations. Beagle dogs were orally or intravenously administered with neoline for pharmacokinetic and absolute bioavailability study. Good linear relationship of neoline was found over the range of 0.1-4 mg x L(-1) (R2 = 0.9982) and 2-100 microg x L(-1) (R2 = 0.9945). Intra-and inter-day precision, expressed as the relativestandard (RSD) were less than 5.0%. Accuracy, expressed as the relative error (RE) was within 90.0%-115%. The recovery of neoline in dog plasma was more than 80%. After 6 mg x kg(-1) for ig and 1 mg x kg(-1) for iv administration of neoline, the main pharmacokinetic parameters were analyzed with Winnonlin software. t(1/2) were (313.88 +/- 63.18), (236.33 +/- 229.84) min, and AUC(0-infinity) were (58,027.40 +/- 14,132.69), (473,578.02 +/- 82,333.08) min x microg x L(-1) for ig and iv administration respectively. The absolute bioavail ability was (73.15 +/- 10.29) %. The method of UPLC-Q-TOF-MS described in the report was sensitive, reliable and specific, and suitable for pharmacokinetic study of neoline in Beagle dog. The high absolute bioavailability of neoline in dog suggested good absorption of neline which was worth of further investigation.

OBJECTIVETo study the clinical effect of development theory based acupuncture on early cerebral palsy (CP) infants with parafunctional sitting position.

METHODSTotally 120 early CP infants were randomly assigned to two groups equally, the treatment group and the control group. All received acupuncture combined with training rehabilitation. Patients in the treatment group adopted acupuncture based on infants development theory, while those in the control group were treated by head acupuncture. Sitting functional points in Gross motor function measure (GMFM) 88 were observed in different groups and infant patients of various types before and after treatment. Root mean square (RMS) signals of sitting correlated muscles (latissimus dorsi, erector spinae, rectus abdominis) were recorded by surface electromyography (sEMG). The effective rate was evaluated by Nimodipine method.

RESULTSCompared with before treatment, sitting functional points were significantly improved in the two groups (P<0.01). After treatment, it was higher in the treatment group than in the control group (P<0.01). The advance amplitude was higher in CP infants of the spastic type and the hypotonic type than other types (P<0.01). Along with sitting process, latissimus dorsi RMS signals were gradually tapered, erector spinae RMS signals were gradually enhanced, and rectus abdominis RMS signals were slightly weakened. Compared with the control group, latissimus dorsi RMS signals obviously decreased, and erector spinae RMS signals obviously increased in the treatment group after treatment (all P<0.01). The total effective rate was higher in the treatment group than in the control group (89.29% vs. 77.78%, P<0.05).

CONCLUSIONInfants development theory based acupuncture could effectively elevate dorsi-extensor muscles force, improve sitting position of 8 months to 1 year old CP infants with parafunctional sitting position.

Depression is a very common mental health problem in our modern society. Stress is involved in the provocation of depression. The pathogenesis of depressive disorder is still not well known. The development of neuroendocrine immunology opens a new sight for clarification of mechanism underlying stress-induced depression. Chronic stress activates peripheral and central immune systems accompanied with the release of inflammatory mediators, including cytokines. Activated immune system mediates the process of depression through the interaction with neuron system and neuroendocrine system, including regulating the monoamine neurotransmitter system in synthesis, metabolism and reuptake, inducing the overactivation of hypothalamus-pituitary-adrenal (HPA) axis and its negative feedback regulation, and reducing neurogenesis. This present paper reviews the cytokines mechanisms underlying stress-induced depression.

AIM:To determine the role of nuclear receptor subfamily 6,group A,member 1 (NR6A1) in vascular smooth muscle cell (VSMC) apoptosis.METHODS:NR6A1 protein was over-expressed in the VSMCs by infection of adenovirus.The effect of NR6A1 on the viability of VSMCs was measured by MTT assay.DAPI staining,TUNEL staining and caspase activity assay were conducted.DNA microarray was used to quickly screen the target genes of NR6A1.The effect of receptor-interacting serine/threonine-protein kinase 3 (RIPK3) silencing on NR6A1-induced apoptosis of the VSMCs was further analyzed.RESULTS:Adenovirus-mediated over-expression of NR6A1 induced the apoptosis of VSMCs.The RIPK3 gene expression was up-regulated by NR6A1 over-expression in the VSMCs.NR6A1-induced VSMC apoptosis was inhibited by RIPK3 silencing.CONCLUSION:NR6A1 promotes VSMC apoptosis by up-regulating the RIPK3 gene expression.

OBJECTIVETo study the relationship between E-cadherin gene expression and the methylation status of E-cadherin 5' CpG islands in acute myeloid leukemia (AML).

METHODSReverse transcription-PCR (RT-PCR), flow cytometry and methylation specific PCR were used to analyze the E-cadherin gene and protein expression and its 5' CpG island methylation status respectively in bone marrow cells from 55 AML patients and 7 normal controls.

RESULTSAML cells displayed a significant reduction or lack of E-cadherin gene and protein expression, the positive rates were 23.6% and 18.2% (P < 0.01), respectively. All normal bone marrow cells were E-cadherin positive. Thirty-eight of the 55 patients (69.1%) were E-cadherin 5' CpG island methylated whereas the normal controls were completely unmethylated. Twenty-nine of thirty-one (93.5%) E-cadherin-negative samples showed abnormal hypermethylation of the E-cadherin CpG islands.

CONCLUSIONExpression downregulation and methylation of E-cadherin gene in AML suggest that it might be an important event in AML. E-cadherin methylation was associated with the inhibition of E-cadherin gene and protein expression in AML.
