ResultTwo treatment courses later, there was no significant difference in comparing the strephenopodia score between the acupuncture group and rehabilitation group (P>0.05); the strephenopodia score in the united group was significantly different from that in the acupuncture group and rehabilitation group (P<0.05), and the improvement in strephenopodia in the united group was superior to that in both acupuncture group and rehabilitation group.ConclusionWarming-unblocking Yin Heel Vessel plus rehabilitation can produce a content efficacy in treating post-stroke strephenopodia.

BACKGROUND:Bronchial asthma is considered general y to have an association with Th2 immune response disease, but there is no ideal treatment. Bone marrow mesenchymal stem cel s as a kind of adult stem cel s not only have the multipotent differentiation and proliferation capacity, but also have low immunogenicity and immunoregulation ability. OBJECTIVE:To investigate the effect of culture supernatant of bone marrow mesenchymal stem cel s on lung inflammation of bronchial asthma mice. METHODS:Twenty experimental mice were randomly divided into control and experimental groups, 10 mice in each group. At 0 and 14 days, intraperitoneal injection of ovalbumin induced sensitization in mice, and at 24-26 days, aerosolized ovalbumin solution was used for excitation. From the 24th day, in the experimental group, bone marrow mesenchymal stem cel supernatant was intraperitoneal y injected at 2 hours before excitation;meanwhile, normal saline was injected in the control group. At the last of excitation, the mice were sacrificed under anesthesia to take serum samples, bronchoalveolar lavage fluid and lung tissues. RESULTS AND CONCLUSION:(1) Mice in the control group appeared to have abnormal lung tissue structure, and there were a large amount of eosinophils and monocytes in the submucosa and muscularis. However, lung inflammation was relieved in the experimental group after bone marrow mesenchymal stem cel treatment. (2) The levels of interleukin-17 in the bronchoalveolar lavage fluid and serum were significantly lower in the experimental group than the control group (P<0.05), but there was no difference in the levels of interleukin-4 between the two groups (P>0.05). These findings indicate that the intraperitoneal injection of bone marrow mesenchymal stem cel s can ease lung inflammation and reduce levels of inflammatory markers in the bronchoalveolar lavage fluid and serum of bronchial asthma mice.

Objective To explore the correlation of urine albumin and creatinine ratio(UACR)and short -term prognosis in patients with acute ischemic stroke (AIS).Methods 112 patients with AIS were selected as the research subjects.The admission UACR and related laboratory examination indexes were detected,the US national institutes of health stroke scale (NIHSS)scores,and 28 d after admission of the modified Rankin scale (mRS) prognostic score were recorded.The NIHSS 5 or more points and NIHSS <5 points,different levels and UACR patient observation index between the different prognosis group were compared.Results NIHSS 5 or more group of patients on admission UACR level[(15.41 ±3.21 mg/g)]was higher than the NIHSS <5 patients (9.52 ±2.04)mg/g (t =12.214,P <0.001);UACR acuity 11.60mg/g group in NIHSS of 5 or more proportion of patients (87.5%),mRS score >2 points (82.1%),the proportion of the recent death patients (23.2%)than the proportion of UACR <11.60mg/g,the proportion of the group (32.1%,25.0%,7.1%;the chi -square values 33.509,34.476,5.598,all P <0.050);MRS score >2 groups of patients UACR level[(16.10 ±3.29)mg/g]was higher than that in patients with mRS score 2 points or less (8.38 ±1.95)mg/g(t =20.132,P <0.001);Pearson correlation analysis showed that the standard of UACR and NIHSS score (r =0.412,P <0.05 ),high -sensitivity C -reactive protein (hs -CRP)(r =0.473,P <0.050),white blood cell count (WBC)(r =0.442,P <0.050),fasting plasma glucose (FPG)(r =0.375,P <0.050)were positively correlated.Multiariable Logistic regression analysis showed that UACR (OR =1.587,P <0.050)was a recent independent risk factors of poor prognosis in patients with AIS. Conclusion UACR the illness severity and recent prognosis of patients with AIS is closely related to high levels of UACR may be recent independent risk factors of poor prognosis in patients with AIS.

Young faculty are an essential part of a university's strength and is important for its sustainable development.And their scientific research capability is associated with the long-term development of the university.At present,there are 4 major problems with the development of young faculty's research capabilities,which include their relatively single academic knowledge structure,insufficient experience in writing proposals,insufficient opportunities for academic exchange,and inequity in resource allocation.Establishing a training mechanism may help solve some of the problems and promot their development.The research management department of a university must abandon erroneous traditional management concepts,provide research training seminars,develop a new mechanism to stimulate academic exchange,design a system for short-term laboratory rotations,and promote the participation of your faculty in major research projects.These may bring about marked improvement in the improvement of young faculty's research capabilities.

Embodied as an abstract concept as well as concrete regulations and material environment on the campus,the campus culture is the organizational culture among universities,which plays a significant role in enhancing students' quality of career starting.Similar to its social culture,the American campus culture is characterized by a strong personal heroism thus is known as a "cowboy culture".As the so-called "dragon culture",the Chinese culture is a more conservative one and thus lack of innovation-oriented career starting concepts among Chinese university students.Therefore,in order to effectively carry out entrepreneurship education in colleges and universities,the innovation-oriented campus culture should be constructed,students' entrepreneurship conception strengthened,thus students' sense of career starting and mental status be enhanced.
