Objective To explore the effect of a training based on instructional video modeling designed from the mirror neuron theory on executive dysfunction after stroke. Methods 40 stroke inpatients with executive dysfunction from July, 2014 to July, 2015 were divided into control group (n=20) and observation group (n=20). The control group accepted executive rehabilitation training, while the observation group were asked to see the video of executive rehabilitation task before training. They were assessed with Behavioral Assessment of the Dysexecutive Syndrome (BADS) before and after intervention. Results The total score and scores of subtests except Rule Shift Cards and Key Search increased more in the observation group than in the control group (t>2.9, P<0.05). Conclusion Rehabilitation video as a visual stimulus for exercise training based on the mirror neuron theory could improve executive function recovery of stroke patients with executive dysfunction.

Objective To construct a lentiviral vector carrying CRKL gene RNA interfering( RNAi ).Methods The CRKL RNAi was selected and subcloned into the lentiviral vector,pGCL-GFP(including U6 promotor and green fluorescent protein),generating the lentiviral vector LV-shCRKL.The corrected CRKL was confirmed by endoenzyme digestion ,sequencing.Recombinant lentiviruses were produced by 293T cells following the eo-transfection of LV-shCRKL,with the packaging plasmids pHelper1.0 and pHelper2.0.The virus titer was detected by GFP expressions in 293T cells.Results Plasmid LV-shCRKL carried the correct sequence.The recombinant lentiviruse LV-shCRKL could be produced by co-transfection of LV-shCRKL to 293T cells.Conclusion The recombinant lentiviruse vector LV-shCRKL is constructed successful.

Objective To investigate the effects of alpha-melanocyte-stimulating hormone (alpha-MSH) on the production of tumor necrosis factor-alpha (TNF-alpha) and intedeukin-10 (IL-10) by peri-pheral blood monohuclear cells (PBMCs) from patients with psoriasis vulgaris. Methods Heparinized peri-pheral blood was obtained from 20 patients with psoriasis vulgaris and 10 healthy human controls. PBMCs were isolated, cultured in complete medium, and stimulated with phytohemagglutinin (PHA) alone, the com-bination of PHA and various concentrations of alpha-MSH, or nothing. After another 48-hour culture, ELISA and real-time PCR were performed to measure the secretion levels of TNF-alpha and IL-10 in the super-natants of cultured PBMCs as well as the mRNA expression levels of TNF-alpha and IL-10 in PBMCs. Results The secretion level of TNF-alpha in the supematants of patient-derived PBMCs stimulated by nothing or PHA alone was significantly higher than that from normal control-derived PBMCs (329.87 ± 99.33 ng/L vs 116.95 ± 37.15 ng/L, 1756.01 ± 183.60 ng/L vs 1287.30 ± 152.36 ng/L, both P<0.01). alpha-MSH of all tested concentrations (10-13, 10-11, 10-7,mol/L) could inhibit the secretion of TNF-alpha by PBMCs com-pared with PHA alone (all P < 0.01), and the maximum effective concentration was 10-13 mol/L. On the con-Wary, a significant decrease was observed in the secretion level of IL-10 in the supematants of patient-derived PBMCs stimulated by nothing or PHA alone compared with normal control-derived PBMCs (P <0.05 or 0.01). Moreover, the secretion of IL-10 by PBMCs was promoted by alpha-MSH of all tested con-centrations (P < 0.01 or 0.05), with the maximum effective concentration being 10-13 mol/L (P < 0.01). The alpha-MSH of 10-13 mol/L down-regulated the mRNA expression of TNF-alpha (P < 0.001), but up-regnlated that of IL-10 (P < 0.001) in PHA-stimulated PBMCs from patients. Conclusion alpha-MSH can regulate the production of TNF-alpha and IL-10 by PHA-stimulated PBMCs from patients with psoriasis vulgaris.

Objective To observe the effects of Jieyu-Chufan capsule(JCC) on the behavior and the monoamine neurotransmitter content of cerebral in depression mouse model and explore its mechanism. Methods The ICR male mouse were randomly divided into seven groups according to their weights(the model group, the low, middle and high doses group, Baiyoujie group, the amitriptyline group, the normal control group). The low, middle and high doses group were given JCC with 1.250, 2.500, 5.000 g/kg separately by intragastric administration. Baiyoujie group was given 0.014 g/kg Baiyoujie by gavage. The amitriptyline group was given 0.050 g/kg amitriptyline by gavage. The model group and the normal control group received the same volume of distilled water intragastrically. The drugs were administrated once a day. The brepharoptosis and movement conditions of mouse were observed after 22 days. The monoamine neurotransmitter content of each group was measured after 25 days. Results Compared to the model group, the number of mouse with brepharoptosis decreased in the high dose group after 1, 2, 6 hour with reserpine injection (P<0.05 or P<0.01);the number of mouse came out from the circle increased after 4 hours with reserpine injection (P<0.05 or P<0.01);the content of NA (880.45 ± 428.81 ng/g, 875.98 ± 449.33 ng/g vs. 299.92 ± 267.08 ng/g) and DA (2 305.99 ± 530.37 ng/g, 2 169.99 ± 278.19 ng/g vs. 1 439.34 ± 357.33 ng/g) in the middle and high dose group increased (P<0.01);the content of 5-HT (781.43 ± 135.10 ng/g vs. 492.01 ± 192.80 ng/g) in the middle group increased (P<0.01). Conclusions JCC showed an antidepression influence in depression mouse model induced by reserpine. The mechanism may be related to regulating the level of monoamine neurotransmitter in the nervous centralis .

Objective:To understand the coronavirus disease 2019(COVID-19)prevention and control work and the problems and difficulties faced by non-government primary medical institutions in China during the epidemic period.Methods:A survey on the coronavirus disease 2019(COVID-19)prevention and control work of non-government primary medical institutions was conducted on April 14 to 21, 2020 with the self-designed questionnaire. The questionnaire contained three parts: the first part was basic information of medical staff in non-government primary medical institutions, including position and institutional information; the second part was the status quo of non-government primary medical institutions participating in the prevention and control of COVID-19, including the specific work and difficulties faced by the responders during the epidemic period; and the third part was the prevention and control effect of COVID-19 in the responders′ institutions, including whether there were confirmed cases and infected medical staff. An online invitation was issued among the members of General Practice Branch of Chinese Non-government Medical Institution Association. The invited participants included the heads, general practitioners and other medical personnel of the non-government primary medical institutions the invited participants voluntarily scanned the online two-dimensional code to fill in.Results:A total of 761 individuals in primary health institutions from 20 provinces, municipalities and autonomous regions in China participated in the survey. There were 290 (38.1%) men and 471 (61.9%) women with age of 40(32, 48) years; 83.0% (632/761) had worked for more than 5 years; 33.8% (257/761) owned primary professional titles and 33.0% (251/761) owned intermediate titles. Among all participants 28.5% (217/761) were general practitioners, 26.9% (205/761) were institutions/department managers, 14.6% (111/761) were specialists and 40.3% (307/761) were other related personnel. A total of 549 institutions continued to operate during the epidemic period and 96.5% (530/549) participated in the work related to the prevention and control of the epidemic, including prescreening and triage, health consultation, follow-up of suspected patients, donation, quarantine of suspected cases, follow-up of close contacts/discharged patients, diagnosis and treatment of patients with new coronavirus pneumonia. 44.7% (340/761) of respondents participated in the epidemic prevention as front-line staff and directly contacted patients/suspected patients, and 63.1% (480/761) participated in the epidemic prevention work of primary medical institutions, including clinical outpatient service, prescreening triage and screening. The working sites were not limited to the institutions, but also other sites including high-speed railway station. The 97.8% (744/761) responders expressed their willingness to participate in epidemic prevention work under the unified leadership and command of the state. The 63.9% (486/761) of the responders were worried about the lack of protective equipments and measures, and 90.4% (688/761) respondents showed that they needed medical supplies (protective equipment: masks, goggles, protective gowns, etc.).Conclusion:The participation of non-government primary medical institutions and their staff in COVID-19 infection prevention and control is a key component of the epidemic prevention process.

AIM: To observe the changes in nitric oxide(NO) and peroxynitrite anion (ONOO - ) in the injuried lung following the ischemia-reperfusion of hind limbs and evaluate the contribution of NO and ONOO - to tissue injury. METHODS: A model of hind limbs ischemia was made by clamping infrarenal aorta with a microvascular clip and lung injury occurring after reperfusion. Lung tissue was obtained from the animals received sham operation(group 1),4 hours ischemia without reperfusion(group2), 1 hour reperfusion following 4 hours ischemia (group3) and 4 hours reperfusion following 4 hours ischemia (group4) . The contents of MDA, NO - 2/NO - 3 and the activities of SOD in the lung were examined. Immunohistochemical technique was used to determine the immunoreactivity to iNOS and nitrotyrosine(NT)-a specific "footprint" of peroxynitrite.
