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.     

Unsupervised fuzzy clustering analysis supports behavioral cutoff criteria in an animal model of posttraumatic stress disorder.

BACKGROUND: Unsupervised fuzzy clustering (UFC) analysis is a mathematical technique that groups together objects in the multidimensional feature space according to a specified similarity measurement, thereby yielding clusters of similar data points that can be represented by a set of prototypes or centroids. METHODS: Since clinical studies of mental disorders distinguish between affected and unaffected individuals, we designed an inclusion/exclusion criteria (cutoff behavioral criteria [CBC]) approach for animal behavioral studies. The effect of classifying the study population into clearly affected versus clearly unaffected individuals according to behaviors on two behavioral paradigms was statistically significant. RESULTS: Here the raw data from previous studies were subjected to UFC algorithms as a means of objectively testing the validity of the concept of the CBC for our experimental model. The first UFC algorithm yielded two clearly discrete clusters, found to consist almost exclusively of the exposed animals in the one and unexposed animals in the other. The second algorithm yielded three clusters corresponding to animals designated as clearly affected, partially affected, and clearly unaffected. The algorithm for physiological data in addition to behavioral data failed to elicit discrete clusters. CONCLUSIONS: The UFC analysis yielded data that support the conceptual contention of the CBC and lends additional validity to our previous behavioral studies.

Water- and fat-suppressed proton projection MRI (WASPI) of rat femur bone.

Investigators often study rats by microCT to investigate the pathogenesis and treatment of skeletal disorders in humans. However, microCT measurements provide information only on bone mineral content and not the solid matrix. CT scans are often carried out on cancellous bone, which contains a significant volume of marrow cells, stroma, water, and fat, and thus the apparent bone mineral density (BMD) does not reflect the mineral density within the matrix, where the mineral crystals are localized. Water- and fat-suppressed solid-state proton projection imaging (WASPI) was utilized in this study to image the solid matrix content (collagen, tightly bound water, and other immobile molecules) of rat femur specimens, and meet the challenges of small sample size and demanding submillimeter resolution. A method is introduced to recover the central region of k-space, which is always lost in the receiver dead time when free induction decays (FIDs) are acquired. With this approach, points near the k-space origin are sampled under a small number of radial projections at reduced gradient strength. The typical scan time for the current WASPI experiments was 2 hr. Proton solid-matrix images of rat femurs with 0.4-mm resolution and 12-mm field of view (FOV) were obtained. This method provides a noninvasive means of studying bone matrix in small animals.

When stress is mental illness: A study of anxiety and depression in employees who use occupational stress counselling schemes

A previous study found that 86 per cent of employees (n = 111) who experience stress in the workplace and sought help from their workplace counselling schemes (Employee Assistance Programmes) had serious mental health problems, but the low participation rate (24 per cent) restricted generalizability and the measure used [General Health Questionnaire (GHQ‐12)] did not allow diagnosis. The present study (n = 58) improved the participation rate to 35 per cent and used a different version of the original measure (GHQ‐28) that allowed diagnostic differentiation as well as validation of the original findings. This new study found almost exactly the same high levels of mental health problems existed (86 per cent) in employees who remained at their work and that participants had higher rates of anxiety than depression. This finding is at variance with the usual co‐morbid presentation of anxiety and depression found in community based mental health services and suggests that depression may be an important differentiating factor between those who can remain at work and use counselling and those who cannot. There are implications for those who provide mental health services. The results of this study further reinforce the suggestion that workplace stress may be yet another name for common mental health problems that require professional help and treatment.

蛇毒抗高凝状态酶、氟尿嘧啶对BEL-7404细胞作用的实验研究

目的通过蛇毒抗高凝状态酶（AHCSE）、氟尿嘧啶（5-FU）对人肝癌细胞BEL-7404（简称7404细胞）、正常LO2肝细胞（简称LO2细胞）作用的比较，研究AHCSE对肝癌的作用以及探讨其可能的作用机制。方法应用光学显微镜、透射电镜、MTT法、TUNEL、FCM等方法观察7404细胞、LO2细胞经过AHCSE、5-FU处理后，细胞形态学、生物化学等方面的变化。结果7404细胞、LO2细胞经过AHCSE、52FU处理后，发生了形态学改变；小剂量AHCSE对7404细胞具有很强的抑制作用，但对LO2细胞几乎无影响；随着剂量的加大，AHCSE对7404细胞抑制率上升不明显，但是出现对LO2细胞的抑制作用。经AHCSE作用后，7404细胞发生了凋亡，凋亡率随AHCSE浓度的增加而增加；与5-FU对7404细胞作用相似，但5-FU对LO2细胞抑制作用明显增强。结论AHCSE、5-FU对BEL-7404细胞均有很强的抑制作用，诱导细胞凋亡是其作用机制之一，AHCSE可能成为一种新的肝癌细胞凋亡的诱导剂。     

The Relationship Between Psychogenic Cough and the Diagnosis and Misdiagnosis of Asthma: A Review

The differential diagnoses of persistent nonproductive cough include numerous pulmonary and nonpulmonary organic disorders as well as functional illnesses. Many diseases can cause cough, and several studies have shown asthma among the most common etiologies associated with chronic cough in adult nonsmokers, as well as children. Psychogenic cough and its relationship to asthma and other asthma-like illnesses is complex since distinct maladies with similar features may coexist individually or in combination in any given patient. While chronic cough may occur as a sole presenting manifestation of bronchial asthma in all age groups, recent findings suggest that most children with persistent cough without other respiratory symptoms do not have asthma. Since several organic, as well as functional diseases, may present with persistent cough as their sole manifestation in either adults or children, cough should not be used as a single or major determinant to diagnose and treat asthma, especially when empirically focused therapy trials fail. Given the range of illnesses causing cough, no single management guideline can be expected to be universally effective.     

Evaluating anxiety in patients attending optometric practice

Although anxiety is a well-established obstacle to the delivery of effective health care, there have been no attempts to measure it in the optometric consulting room. In this paper, we introduce physiological and psychological techniques that may be used to evaluate anxiety and arousal in the consulting room and present data from a small group of patients attending for a routine eye examination. Specifically, arousal was assessed before, during, and after the examination by measuring skin conductance in five patients. Anxiety was evaluated using the State-Trait Anxiety Inventory. Our data confirm the ability of these techniques to quantify arousal and anxiety in the optometric consulting room and reveal a previously unknown but important facet of the eye examination. We conclude that these techniques are suitable for use in further experimental work and may be used to identify factors capable of reducing anxiety in the optometric consulting room.
