Circulation of Development Factors Promoted by Innovation of Land Management Under Background of Rural Vitalization:A Case Study of Tengtou Village in Zhejiang Province,China

Land is the space carrier for the existence and flow of other development factors.Activating rural land and promoting the circulation of other development factors through land management innovation is necessary to realize rural vitalization.This paper identifies the connotation of factor flow in the rural vitalization context,the action mechanism of land management innovation to boost the flow of development factors,the issues and obstacles restricting factor circulation,and the realization mechanism of the flow of development factors in rural vitalization.Based on the analytic paradigm constructed in the paper,the successful practice of promoting the flow of development factors through innovative land management in a model village is examined.The results show that:1)the unreasonable systems characterized by the land use system in rural areas are the main obstacles causing circulation issues in development factors.It is essential to engage in comprehensive reform to break down these long-lasting obstacles to the smooth flow of development factors.2)The land should play a leading role in the circulation of development factors in the background of rural vitalization;the main purpose of land management innovation is to activate the land factor,thereby promoting the circulation of other factors.3)The activated land factor will act as a‘trigger’to promote capital and technology in rural settings and use capital and technology to attract the inflow of talents and the return of migrant workers,whereby the population factor will act as a‘catalyst’for the cultivation of rural culture,bringing about the integration of various development factors.4)The innovation of land use and management,increased funding,and new technologies have brought multiple talents to Tengtou Village.The high-frequency mutual feedback between the village’s own and the external development factors resulted in its successful integration of industrial development.

Onecut transcription factors in retinal development and maintenance

The retina and its development： The retina is an essential part of the visual system. A myriad of eye diseases are characterized by retinal degeneration, caused by either genetic or environmental factors. This underscores the importance of studying the genetic and molecular mechanisms that regulate the generation and maintenance of neurons in the mammalian retina. Our recent studies demonstrate that two related transcription factors Onecutl （Ocl） and Onecut2 （0c2） regulate multiple cell fates in the mouse retina, and their absence results in progressive retinal neurodegeneration （Wu et al., 2012, 2013; Sapkota et al., 2014）.

Risk factors for the occurrence and development of Binswanger disease: A controlled observation

BACKGROUND： Some scholars think that hypertension is the major risk factor to cause Binswanger disease （BD）, however, BD is also found in some persons with normal blood pressure, so we presume that some other factors, such as diabetes mellitus, hyperlipemia, coronary heart disease and transient ischemic attacks and so on, might participant in the onset of BD. OBJECTIVE： To comparatively observe the difference in accompanying diseases, transcranial doppler （TCD） performance, blood glucose and blood lipid level between BD patients and healthy subjects who received health examination, and between BD patients with different disease condition. DESIGN ： Case-control analysis SETTING ： Department of Emergency, Qingdao Municipal Hospita PARTICIPANTS： Totally 126 patients with BD, 65 male and 61 female, aged from 67 to 85 years old, who hospitalized in the Medical School Hospital of Qingdao University and Qingdao Municipal People＇s Hospital, were chosen, serving as BD patients group. All the patients met the clinical diagnostic criteria of BD introduced by Bennett et al. Another 126 persons, 65 male and 61 female, aged ranging from 67 to 80 years, who received health examination in the same hospital, were homeochronously chosen, serving as control group. Informed consents were obtained from all the subjects. METHODS ： After being admitted, all the subjects including BD patients and persons who homeochrenously received health examination in the same hospital were given examinations of blood pressure, blood lipid, blood glucose, electrocardiogram （ECG） and TCD. Fifty-seven patients with BD were in the stable period and 69 in the progressive period （Stable period： no local or subcortical function disorder found, and no changes in the range of white matter lesion showed by CT and/or MRI in recent 3 months; Progressive period： with local or subcortical function disorder and increase in the range of white matter lesion showed by CT and/or MRI in recent 3 months）. According to intimal thickening of carotid artery and vertebral artery preformed by TCD, BD was graded as mild intimal thickening （〈 1.1 mm）, moderate intimal thickening （1.1 to 1.2 mm） and severe intimal thickening （〉 1.2 mm）. MAIN OUTCOME MEASURES ： Comparison of the ratio of BD patients with accompanied diabetes mellitus, hypedipemia, coronary heart disease and transient ischemic attacks, TCD performance, blood glucose and blood lipid level between BD patients group and control group, and among BD patients with vadous disease conditions. RESULTS： Totally 126 BD patients and 126 subjects who received health examination all participated in the result analysis. Intergroup comparison： ①The ratio of BD patients with accompanied hypertension, diabetes mellitus, hypedipemia, transient ischemic attacks and coronary heart disease was 91.3%, 46.8%, 42.9%, 81.7% and 46.0% respectively in the BD patients group, and that was 36.5%, 17.5%, 15.9%, 34.1% and 34.1%, respectively in the control group. Significant difference existed between two groups （x^2=86.201, 24.907,25.660,58.620,9.900, P 〈 0.01 ）.②Compared with control group, anterior, middle cerebral and vertebrobasilar arteriosclerosis and insufficient cerebral blood supply existed significantly in BD patients with different disease condition （x^2=40.34,7.585,15.429, P 〈 0.01 ）.③Compared with control group, the level of blood glucose, total cholesterol and triglyceride of BD patients increased significantly （t=6.939,3.891,3.711 ,P 〈 0.01 ）. Comparison among BD patients with different disease condition： ① Compared with stable period, transient ischemic attacks and coronary heart disease were found much in the BD patients at progressive period, with significant difference （x^2=7.196,13.517,P 〈 0.01 ）.② Mild arteriosclerosis at stable period was found in 17 cases, and significant difference existed compared with progressive period （x^2=6.523,P 〈 0.05）.③ There was no significant difference in the blood glucose and blood lipid level （t=-1.755 6,0.583 1,0.824 6, P 〉 0.05）. CONCLUSION： Hypertension, cerebral arteriosclerosis, diabetes mellitus, hypedipemia, coronary heart disease and transient ischemic attacks have important effects on the onset of BD; Transient ischemic attacks and coronary heart disease can worsen the symptoms of BD patients.

On Dynamic Social Factors for Development of China’s Human Rights Theory

China＇s mainstream human rights theory has undergone tremendous changes since the reform-and-opening scheme was kicked off in the early 1980s. ＂Human rights,＂ which used to be seen as a concept of capitalist ideology, is now an important part of the Chinese system of socialist values.

Function of pioneer neurons specified by the basic helix-loop-helix transcription factor atonal in neural development

Basic helix-loop-helix （bHLH） transcription factors regulate the differentiation of various tissues in a vast diversity of species. The bHLH protein Atonal was first identified as a proneural gene involved in the formation of mechanosensory cells and photoreceptor cells in Drosophila （larman et al., 1993, 1994）. Atonal is expressed in sensory organ precursors and is required and sufficient for the development of chordotonal organs （Jar- man et al., 1993）. Moreover, Atonal expression is observed in the developing eye and is essential for the differentiation of R8 photoreceptors, which are the first photoreceptors that appear during development. Atonal is not involved in the formation of other photoreceptors （R1-R7） directly. However, R8 photore- ceptors recruit other photoreceptors from the surrounding cells （Jarman et al., 1994）.

Analysis of 300 consecutive cases of pancreatic adenocarcinoma in a single-center in China

BACKGROUND： Most of the reports on the prognostic indicators of patients with pancreatic adenocarcinoma are from developed countries. The present study focused on the prognostic indicators of Chinese patients with pancreatic adenocarcinoma. METHODS： A total of 300 patients with pancreatic adenocarcinoma who had undergone curative resection were included. The resection and R0/R1 resection rates for adenocarcinomas from different parts of the pancreas were calculated and clinical characteristics were analyzed.RESULTS： In 3427 patients diagnosed with pancreatic adenocarcinomas, only 300（8.8%） were eligible for radical resection. The total median survival of these patients was 19 months, and their 1-, 3-, and 5-year survival rates were 72.5%, 28.0% and 23.4%, respectively. The prognostic factors included socioeconomic status, smoking history, symptoms, high blood glucose, and various tumor characteristics, including perineural and vascular invasion, lymph node metastases, and CA19-9 levels before and after operation. Operation-associated prognostic indicators included operation time, blood loss and transfusions, pancreatic fistula, and complications. Independent predictors of mortality included poor socioeconomic status, smoking history, symptoms, CA19-9, perineural invasion and lymph node metastasis, grade of fistula and complications. Patient survival was not correlated with either resection margin or adjuvant chemotherapy in multivariate analysis.CONCLUSIONS： The survival rates of patients with curative resection for pancreatic adenocarcinoma in China are close to those in developed countries, but curative resection rate is far below. Socioeconomic status, symptoms, and CA19-9 are the three most prominent prognostic factors, which are helpful in patient selection and perioperative care.

Where are the theca cells from: the mechanism of theca cells derivation and differentiation

Mammalian follicles are composed of oocytes,granulosa cells,and theca cells.Theca cells form in the secondary follicles,maintaining follicular structural integrity and secreting steroid hormones.Two main sources of theca cells exist:Wilms tumor 1 positive(Wt1+)cells native to the ovary and Gli1+mesenchymal cells migrated from the mesonephros.Normal folliculogenesis is a process where oocytes,granulosa cells,and theca cells constantly interact with and support each other through autocrine and paracrine mechanisms.The proliferation and differentiation of theca cells are regulated by oocyte-derived factors,including growth development factor 9 and bone morphogenetic protein 15,and granulosa cell-derived factors,including desert hedgehog,Indian hedgehog,kit ligand,insulin-like growth factor 1,as well as hormones such as insulin and growth hormones.Current research on the origin of theca cells is limited.Identifying the origin of theca cells will help us to systematically elaborate the mechanisms of follicular formation and development.
