Using Huntingtin Knock-In Minipigs to Fill the Gap Between Mouse Models and Patients with Huntington's Disease

Huntington＇s disease （HD） is an inherited autosomal dominant neurodegenerative disease characterized by pro- gressive motor deficits, cognitive decline, and psychiatric symptoms. It is caused by a pathological expansion of CAG trinucleotide repeats in exon 1 of the HD gene, resulting in the translation of a mutant form of huntingtin protein （mutant Htt） with an expanded polyglutamine domain in the N-terminal region [1 ]. Despite great progress in understanding the pathogenesis of HD using multiple mouse models, the exact mechanisms by which mutant Htt induces neuronal dysfunction and death are still not completely clear, and there is no curative treatment for this disease. An important reason is that the mouse, which is the most widely used animal model in HD research, differs from the human in many aspects, including the physiology, drug metabolism, blood-brain barrier, life span, brain volume, and neuroanatomical organization [2]. Thus, it is necessary to establish HD models with higher species than rodents, such as the dog, pig, and non- human primate, so as to bridge the gap between preclinical mouse models and clinical studies.

A STUDY ON THE SERUM PREGNANCY ZONE PROTEIN LEVELS IN PREGNANT WOMEN AND PATIENTS WITH GYNECOLOGICAL TUMORS

In this study, the serum levels of the pregnancy zone protein (PZP) were determined by PZP-single radial immunodiffusion in 708 cases of normal pregnancy, 207 with abormal pregnancy and 188 with gynecological tumors. The results indicated that serum PZP levels in the normal pregnancy was detectable 5 weeks after gestation. It increased with the advance of gestational weeks, and reached a peak level in week 40. The serum PZP levels in 81.7% of patients with threatened abortion but not aborted were within the normal range, and also mostly in those with pregnancy-nduced hypertension, intrauterine growth retardation (IUGR), anencepbalus and ectopic pregnancy; the serum PZP levels in 51.6% of patients with invasive moles and 80.0% with choriocarcinoma, respectively, were lower than in normal controls. In gynaecological tumors, the serum PZP levels were significantly higher in patients with ovarian carcinomas than in those with other ovarian tumors (P<0.01), and in those with endometrial or cervical carcinoma than in those with uterine myomas (P<0.01). These results suggest that measuring the serum PZP levels may be used as an important reference index to observe threatened abortion and to identify trophoblastic diseases and gynecological tumors.

Analysis on The Effective Ways of Strengthening The Cultivation of Communication Ability between Nurses and Patients in Higher Vocational Nursing Education

Nowadays,under the condition of the lack of nursing staff, the state began to cultivate nursing students vigorously, and higher vocational nursing education has gradually become one of the most important majors in many full-time colleges and universities.The students who are trained in professional nursing,after several years of study, they will be gradually distributed to various regions,excellent students will even be sent to hospitals with better conditions and higher medical level.ln fact, the nursing work is not as easy as people know.Nursing workers not only need to directly face different patients,but also need to have certain nursing technology and ability of adjusting to changing circumstances.Cultivating the nursing ability and ability of communicating well with patients of these students is the main purpose of higher vocational nursing education.
