There were no acute schistosomiasis patients and out-break of schistosomiasis endemic. Conclusion The schistosomiasis control mode(“Hubei mode”)is effective significantly.

Objective To construct recombinant plasmids containing HPV18E7 gene ,and explore the optimization condition of its expression in Escherichia coli .Methods The genomic DNA extracted from HeLa cell line which served as a template to the HPV18 E7 gene was amplified using PCR method ;and the amplified product of HPV18E7 gene was connected to the pET-32a(+ ) vector ,which composed the pET-32a(+ )-HPV18E7 recombinant plasmid ;the positive recombinant plasmids were transformed into BL21-DE3-pLysS competent cells and the optimized expression condition was explored in order to obtain a large amount of HPV18E7 oncogenic protein .Results The fragment length of PCR products of HeLa cell genomic DNA was consistent with that of HPV18 E7 gene .In LB medium ,the expression level of the target protein was not high under such conditions as different concentra-tion of IPTG and lactose ,different temperatures and different induction starting amount .Therefore the ZYM-5052 auto-induction medium was tried in this experiment ,and the expression amount of the fusion protein was much higher than that induced with IPTG and lactose .Conclusion The amount of HPV18E7 fusion protein in ZYM-5052 automatic induction medium is much higher than that induced with IPTG and lactose .

AIM:To observe the effects and mechanisms of hydroxyethylstarch (HES) 130/0.4 on no-reflow phenomenon after myocardial ischemia-reperfusion in rats.METHODS: SD rats were randomly divided into 4 groups:sham operation group , ischemia-reperfusion ( IR, treated with normal saline ) group, normal saline ischemia-reperfusion (NS-IR, treated with NS) group and HES ischemia-reperfusion (HES-IR, treated with HES) group.Myocardial infarct size and no-reflow range were determined by staining methods , and the activities of myocardial enzymes ( CK-MB, cTnI and MPO) were measured .Meanwhile , cardiac microvascular endothelial cells of the rat were cultured and divided into 4 groups:control group, hypoxia/reoxygenation (H/R) group, NS-H/R group and HES-H/R group.Acute ischemia reper-fusion models were simulated , and the concentration of calcium ions was measured .The relative cell activity was evaluated by CCK-8 assay, and the apoptotic rate was detected by flow cytometry .RESULTS:In HES-IR group, the myocardial in-farct size, the no-reflow zone, CK-MB, cTnI and MPO activity were all significantly lower than those in IR group ( P<0.05).In microvascular endothelial cells , the concentration of calcium ions and the apoptotic rate in HES-H/R group were significantly decreased, while the relative cell activity increased compared with H/R group (P<0.05).CONCLUSION:HES reduces no-reflow in acute myocardial ischemia-reperfusion .The mechanism may be involved in the inhibition of both the infiltration of neutrophils and the calcium overload of endothelial cells .

Parkinson's disease and sarcopenia are both age-related diseases that seriously affect the quality of life of the elderly.Studies have suggested that Parkinson's disease is related to sarcopenia.Exploring the correlation between them can provide evidence for early identification and prevention of Parkinson's disease patients with sarcopenia.This review summarized the correlation between Parkinson's disease and sarcopenia and possible shared pathways of pathogenesis.

Objective To evaluate the clinical effect of acupuncture on Parkison disease (PD) with systematic review in view of evidence-based medicine (EBM).Methods Articles on clinical effect of acupuncture on Parkinson disease published from the database-established year to May of 2017 we searched from China National Knowledge Internet (CNKI),Wanfang,VIP,Chinese Biomedical Literature Database (CBM),PubMed,and Cochrane Library databases without language limitation.Quality evaluation and data extraction were carried out according to the tool for assessing risk of bias provided by the Cochrane Handbook for Systematic Reviews of Interventions (Version 5.1.0).All statistical analyses were performed with Reviewer Manager Software (Version 5.3;Cochrane Collaboration,Oxford,UK).Assessments were performed with the total effective rate,the scores of each scale (the unified Parkinson disease rating scales-UPDRS and the Webster scale),and the improvement of different clinical manifestation.Results In all,12 randomized controlled trials (RCTs) met our inclusion criterion,a total of 892 patients,including 468 cases in the experimental group (acupunctuer with or without medicine) and 424 cases in the control group (medicine only).Meta-analysis showed favorable results for the experimental group compared to control group in the total effective rate,the total scales of UPDRS and the modified Webster scale [OR =2.16,95％ CI (1.57,2.97),P＜0.01;OR =7.20,95％ CI(4.02,10.37),P＜0.01;OR=3.33,95％ CI(2.13,4.53),P ＜0.01].The experimental group was effective in relieving partial symptoms of PD such as rigidity,postural,gait,bradykinesia compared to the control group,while there was no significant difference in tremor at rest and sit-stand up movements (P ＞ 0.05).Conclusions Acupuncture had certain clinical effect on Parkinson disease,it can relieve the clinical symptoms of Parkinson disease to some extent,and postpone the progression of PD,which improves the quality of life of PD patients.Acupuncture can be recommended as a combination treatment for Parkinson disease.

The delta-opioid receptor (DOR),which is a classic analgesic drug widely existed in the central system and peripheral system,is a kind of inhibitory G-protein coupled receptor with seven transmembrane regions.In addition to pain modulation,the opioid receptors are involved in various physiological and pathological activities through gene or cytokines.This review addresses the influence and possible mechanisms of the delta-opioid receptor in ischemic brain injury,analgesia,anti-anxiety and depression,learning and memory,and Parkinson's disease.

Parkinson's disease (PD) is a neurodegenerative disease characterized by degeneration and deletion of dopaminergic neurons in the substantia nigra and a pathological feature of the Louis body.The clinical manifestations including non motor symptoms and motor symptoms.Cognitive impairment (CI)is one of the most common non motor symptoms in patients with PD,Which includes mild cognitive impairment (MCI) and dementia.MCI is an early manifestation of dementia in PD.Therefore,early diagnosis and treatment of MCI are very important for the prognosis of PD.The epidemiology,risk factors,heredity,biomarkers,imaging,diagnosis and treatment of MCI in PD are reviewed in this paper.

Parkinson's disease (PD) is a type of degenerative disease of the nervous system.In addition to its typical clinical symptoms,non-motor symptoms mainly include sensory disorders,neuropsychiatric disorders and autonomic nerve disorders,which also have serious effects on patients.This article reviews the performance,mechanism of non-motor symptoms to improve clinicians' attention and improve the quality of life for Parkinson's patients.

Parkinson′s disease (PD) is a neurodegenerative disease commonly found in middle-aged and elderly people. It is characterized by resting tremor, bradykinesia, myotonia, and abnormal posture gait. The main pathological changes were the loss of dopaminergic neurons in the substantia nigra and the formation of Lewy bodies in the cytoplasm of the residual neurons. The main component of the Lewy bodies was α-synuclein. And why it causes the degeneration of dopaminergic neurons in the substantia nigra is not known. At present, most studies on Parkinson′s disease focus on the pathogenesis of the disease. More and more evidence shows that respiratory chain injury is a key feature of sporadic PD patients, and the proteins encoded by PD-related genes are related to the disorder of mitochondrial function. We believe that the important mechanism of the disease is impaired mitochondrial function due to environmental and (or) genetic inheritance. This article highlights new advances in mitochondrial dysfunction in Parkinson′s pathogenesis, including mitochondria and cell-mediated immunity, endoplasmic reticulum (ER)-mitochondrial axis, sirtuin-mediated mitochondrial stress response, and the role of microRNA in the etiology of PD. A deeper understanding of these mechanisms may provide inspiration for the development of new targeted therapies.
