Information Fusing Recognition of Traditional Chinese Medicine （TCM） Pulse State Based on Stochastic Fuzzy Neural Network

Based on the fuzzy characteristic of the pulse state and syndromes differentiation thinking mode of TCM, an information fusing recognition method of pulse states based on SFNN （Stochastic Fuzzy Neural Network） is presented in this paper. With the learning ability in parameters and structure, SFNN fuses the measurement information of three pulse-state sensors distributed in Cun, Guan, and Chi location of body for the pulse state recognition. The experimental results show that the percentage of correct recognition with new method is higher than that by single-data recognition one, with fewer off-line train numbers.     

隐匿阴茎的分类和手术治疗

目的：探讨隐匿阴茎的分类和手术治疗方法。方法：手术治疗33例隐匿阴茎患者，年龄l岁3个月-25岁，平均6．2岁。根据Bergeson(1993)的隐匿阴茎的分类标准，埋藏阴茎29例，蹼状阴茎2例，束缚阴茎2例。结果：术后随访2个月-1年，所有患者术后阴茎外观满意，阴茎皮肤与阴茎体附着正常。结论：对隐匿阴茎不能指望青春期发育时耻骨前脂肪组织减少或简单行包茎松解术就能得到解决，正确的分类和恰当的手术治疗才能取得良好效果。     

脑梗死后早发性癫(癎)发作临床特点分析

目的:探讨脑梗死(CI)后早发性癫癎发作(EES)的临床特点。方法:对2643例确诊为CI患者的临床资料进行回顾性研究。结果:CI后EES的发生率为4.58%,女性高于男性(P<0.05);婴幼儿及未成年人高于成年人(P<0.01)和老年人(P<0.01);累及皮质的发生率高于未累及皮质的(P<0.01);EES作为CI首发症状者占49.59%,24h内出现者占76.03%,1周内出现者占94.21%,仅有5.79%在第2周出现;局灶性发作占65.29%,全面性发作占34.71%;给予AEDs治疗发作均可控制,伴有EES的患者病死率高于不伴有者(P<0.05)。结论:CI后EES较为常见,女性多于男性,未成年人的发生率高于成年人及老年人,与梗死部位有关,以局灶性发作为主,抗癫癎治疗有效,临床预后较差。

Electrophysiological study on differentiation of rat bone marrow stromal stem cells into neuron-like cells in vitro by edaravone

To explore the electrophysiological proper-ties of differentiation of rat bone marrow-derived stromal stem cells (rBMSCs) to neuron-like cells in vitro by edaravone, a new type of free radical scavenger. Methods: Stromal stem cells were separated from rat bone marrow with Ficoll-Paque reagent and expanded in different culture medium in vitro, rBMSCs were induced by edaravone containing serum-free L-DMEM. Morphologic observation and Western blot analysis including the ex-pression of Nav1.6, Kv1.2, Kv1.3, Cav1.2 were performed, and whole patch-clamp technique was used. Results: Cyton contraction and long processes were shown in differentiated stromal stem cells. Nav1.6, Kv1.2, Kv1.3 and Cav1.2 were expressed in both differentiated and undifferentiated cells. However, the expression of channel proteins in differentiated cells was up-regulated. Consistently, their resting potential and outward currents were also enhanced in the differentiated cells, which was especially significant in the outward rectifier potassium current. Conclusion: In vitro, neuron-like cells derived from rBMSCs, induced by edaravone, possess electrophysiologi-cal properties of neurons.     

Insulin reduces the BOLD response but is without effect on the VEP during presentation of a visual task in humans.

Functional magnetic resonance imaging (fMRI) based on blood oxygen level-dependent (BOLD) contrast has become an invaluable tool in the assessment of in vivo neuronal activation. Quantification of the BOLD response is determined by the hemodynamic and metabolic changes that occur in response to brain stimulation. However, these changes may vary by changes in insulin, a hormone known to be vasoactive in some tissues. To determine if insulin has an effect on fMRI, we measured the BOLD response to a visual stimulus in five normal volunteers in which insulin was first suppressed and then brought to a high physiological concentration. In addition, we also examined the effect of insulin on activation of the visual cortex as measured by the visual-evoked potential (VEP). We found that the BOLD response measured in the presence of insulin (serum insulin=236+/-29 pmol/L) was significantly lower (P<0.001) than that measured in its absence (serum insulin=8+/-2 pmol/L). Insulin was without effect on P100 amplitude or latency acquired in the presence or absence of insulin in 28 subjects using the same stimulus as that used for the fMRI experiments. Our observations suggest that insulin may have effects on cerebral blood flow and/or metabolism that affect the BOLD signal that are independent of its effects on neuronal activation identified by event related potentials (ERP). These findings highlight the complexity that must be considered when interpreting differences in fMRI responses between groups of subjects that differ in insulin concentration and/or insulin sensitivity.     

Effects of Intraventricular Injection of Calmodulin Antagonist （Trifluoperazine） on Pregnancy in Rats

Injection of TFP (a specific antagonist of CaM) into the lateral ventricles of the rat brain on the fourth day of pregnancy causes marked antifertility effect in 83% of the rats (0% in the control group). Examination with the pontamone blue reaction for the implantation elucidated that the antifertitity effect was due to the blockage of implantation of the follicle. Injection of TFP into the lateral ventricles of the brain markedly reduced the concentration of CaM in hypothalamus, ovary and uterus. Serum progesterone was also reduced. However, injection glven on day 7 was ineffective to terminate the pregnancy. Injection given on certain time of pregnancy was able to reduce the cellular CaM content and to cause antifertitity. This finding demonstrated that CaM played an important rote during the course of pregnancy.
