The frequency content of many biomedical signal s can change rapidly with time. Conventional Fourier spectral analysis techniques are insufficient for analyzing the time-varying spectral content of these signals. By mapping a one-dimensional function of time(or frequency), the time-frequency representation can localize the signal energy in both the time and frequ ency directions. It has been shown that many biomedical signal problems may benefit from time-frequency analysis. The basic method of time-frequency analys is and its application in biomedical signals processing are introduced.

BACKGROUND: Cerebrovascular disease often causes dysfunction of the brain nerve, and nerve cel apoptosis is the important factor of cerebral nerve dysfunction. The excessive expression of c-fos can block the transduction of intracelular signal so that producing some apoptosis-promoting factors, which involve in nerve cel apoptosis process after ischemia injury of brain. Bcl-2 is an inhibited factor. It might to be the key to treat ischemic cerebrovascular disease by inhibiting or reducing the apoptosis of nerve cels after ischemia injury. OBJECTIVE: To investigate the therapeutic effect and mechanism of the Total Flavone of Hawthorn Leaf on chronic cerebral ischemia rats. METHODS: A total of 72 healthy male Sprague-Dawley rats were randomly divided into sham surgery group, model group, Total Flavone of Hawthorn Leaf group and ginkgo leaf group. Permanent bilateral carotid artery ligation was used to prepare chronic cerebral ischemia model in the model group, Total Flavone of Hawthorn Leaf group and ginkgo leaf group. Total Flavone of Hawthorn Leaf group and ginkgo leaf group respectively received 140 mg/kg Total Flavone of Hawthorn Leaf and 12.3 mg/kg ginkgo leaf intragastricaly for 36 days from 36 days after model induction. Model group and sham surgery group received 3.5 mL/kg physiological saline intragastricaly. RESULTS AND CONCLUSION: Compared with the model group, the expression of c-fos protein significantly deceased in the Total Flavone of Hawthorn Leaf group (P < 0.01), Bcl-2 expression levels significantly increased (P < 0.01), and Ca2+ content decreased (P < 0.05). Moreover, no significant difference in above indexes was detected between Total Flavone of Hawthorn Leaf group and ginkgo leaf group (P> 0.05). These data indicated that the protective effect of Total Flavone of Hawthorn Leaf on chronic cerebral ischemia was associated with its inhibition of neuronal apoptosis. Its mechanism of anti-apoptosis might be associated with up-regulating expression of Bcl-2, down-regulating expression of c-fos and decreasing Ca2+ content in brain.

Objective To investigate the maternal and fetal outcomes of pregnant women with subclinical hypothyroidism, and clinical observation of thyroxine replacement. Methods From March 2014 to March 2015, the clinical records of 216 women with subclinical hypothyroidism(including 166 cases with thyroxine replacement), and hypothyroidism(n=69)during pregnancy who delivered at our hospital were reviewed. The maternal complications and neonatal outcomes were compared with 406 healthy women who delivered during the same period. Results The age, number of fetus, and morbidity rate of gestational hypertension were without significant differences in those groups. The morbidity of gestational diabetes in subclinical hypothyroidism group and hypothyroidism group were significantly higher than those in control group(13.4%, 17.4% vs 0.2%, P<0.05). The rate of thyroid peroxidase antibody and thyroglobulin antibody positive in subclinical hypothyroidism group and hypothyroidism group were significantly higher than those in control group(26.9%, 23.2% vs 9.9%; 15.7%, 23.2% vs 8.1%, all P<0.05). No matter treated or not treated in subclinical hypothyroidism group, the preterm birth, Apgar score, low birth weight, birth defects, and infant congenital hypothyroidism were without significant differences as compared to the control group(P>0.05). Further compared those between treated and untreated subclinical hypothyroidism, the results were also without significant difference(P>0.05). Conclusions Subclinical hypothyroidism had no significant influence on pregnancy outcomes and perinatal events. Thyroxine replacement in subclinical hypothyroidism pregnant women also had no significant influence on pregnancy outcomes and perinatal events.

Objective To analyze the clinical characters and identify the risk factors in patients diagnosed with systemic lupus erythematosus (SLE) and thrombotic thrombocytopenic purpura (TTP). Methods We retrospectively analyze the clinical features, laboratorial test results and treatment strategy of 20 SLE patients with TTP diagnosed in the First Affiliated Hospital of Zhengzhou University from 2011 to 2018. Multiple logistic regression model was used to determine risk factors for TTP. Results Among 20 SLE with TTP patients, 16 were female and 4 were male. The median age at diagnosis was 47 (14-74) years old. Three cases of TTP were diagnosed during the treatment of SLE, 16 cases were diagnosed after the diagnosis of SLE, while 1 case was diagnosed before SLE. Logistic analysis showed that the independent risk factors for TTP included Systemiclupus erythematosus disease activity index (SLEDAI)>10, renal and CNS involvement (P<0.05). Conclusion Patients with SLE who have moderate or high disease activity, renal and Central nervous system (CNS) involvement significantly increases the risk of TTP.

Taking " harmony of body and spirit" as the theoretical core in Huangdi Neijing and the functional nature and executive structure of the five emotions system as clues, this paper explores and analyzes the relevant theories of the five emotions system in ancient Chinese medicine literature. It is found that the five emotions system is a highly ordered and integrated collection of five functional states. It often resides in the five zang viscera, it operates between the meridians and the xuanfu through the elevation and movement of the qi, and it is the pivotal point for the operation of the qi and blood of the organism, the interactive conduction of information, and the unity of form, emotion, and qi. Therefore, this paper starts from the point of view of system science. It is proposed that the primordial spirit exercises control over the five emotions and the five emotions provide nutrition to the primordial spirit, and that the two are not " islands of information" but have a dynamic and hierarchical internal connection. The executive structure of the five emotions system, namely, the meridians, the xuanfu, and the five zang viscera, is the pivot, and it is recognized that the operation of the five emotions system is a process with self-organizing characteristics and orderly and eternal motion. We think of the qi, blood, ying, and essence as the basis of occurrence, the meridian as the execution channel, and the xuanfu as the place for the spiritual mechanism to enter and exit; the five zang viscera serve as a dwelling place, and ministerial fire serves as the source of energy. This paper serves as reference for future research related to the executive structure of the five emotions system of traditional Chinese medicine.

Objective To summarize the clinical data of macrophage activation syndrome (MAS) in adult-onset Still's disease (AOSD) patients and provide evidence for clinical diagnosis and treatment. Methods We retrospectively reviewed the clinical data of AOSD with MAS patients in the First Affiliated Hospital of Zhengzhou University from January 2012 to August 2018, and compared with patients with AOSD alone. Data were analyzed by t-test, Mann-Whitney U test, x2 test or Fisher exact test. Results A total of 14 AOSD with MAS patients were enrolled, accounting for 7.6%(14/185) of AOSD patients at the same period, including 2 males and 12 females. The median duration of AOSD in MAS was 1.3 (0.25, 4) months. Compared with the AOSD group, the age of onset was younger in the MAS group (t=-2.038, P=0.037), and the proportion of splenomegaly (t=9.020, P=0.003), pericardial effusion (t=8.663, P=0.003), pleural effusion (t=4.754, P=0.029) was higher. The white blood cell count (t=-4.171, P<0.01), hemoglobin level (t=-2.661, P=0.008), platelet count (t=-5.672, P<0.01), neutrophil count (t=-5.082, P<0.01), albumin (t=-3.426, P<0.01), fibrinogen (t=-5.986, P<0.01), ESR (t=-2.941, P=0.003), CRP (t=-2.014, P=0.044) was significantly decreased, ALT (t=-3.227, P<0.01), AST (t=-3.105, P=0.002), triglyceride (t=-5.612, P<0.01), ferritin>2000 μg/L (t=7.833, P=0.005) was significantly increased. Fourteen patients with AOSD complicated with MAS were treated with glucocorticosteroids, 5 with methylprednisolone, 8 with cyclosporine A, 8 with intravenous immunoglobulin (IVIG), 2 with etoposide, and 1 with tocilizumab. After treatment, 11 cases recovered and 3 cases died. Conclusion Younger AOSD patients tend to complicated with MAS, especially at the early course of the disease, and splenomegaly occur more frequently clinically compared to patients without MAS. When blood cell count, fibrinogen and ESR decreases, triglyceride and ferritin levels increases in AOSD patients, the occurrence of MAS is indicated. Timely treatment can improve the prognosis of patients.
