Meridian syndromes are the required basic knowledge for mastering Science of Meridians, Collaterals and Acupoints but have not brought the adequate attention on the teaching program. The writers discovered' that the content of this section occupied a decisive role for developing the students' clinical thinking ability and, stimulating their interests to learn classical TCM theories. It's necessary to enhance the importance on meridian syndromes during teaching program. The teaching program was discussed in three aspects, named workshop pattern, competitive pattern and multimedia pattern. This teaching method may improve students' interests in the study on classical TCM theories, deepen the understanding on knowledge and motivate students' learning autonomy so that the teaching quality can be improved.

In order to study the character of periodontal ligament cells (PDLCs) attaching on commercially pure titanium (cpTi) by morphology and metrology on the early stage (24 h), 1 x 10(5)/ml PDLCs in 2 ml culture medium were seeded on cpTi discs fixed in 24-well culture plates. Morphology of cell attachment was observed by contrast phase microscope, scanning electron microscope (SEM) and fluroscence microscopy. Cell adhesion was analyzed by MTT at 0.5, 1, 2, 4 h respectively. PDLCs could attach and spread on cpTi discs. SEM showed that PDLCs had pseudopod-like protuberance. PDLCs showed different attaching phases and reached saturation in cell number at 2 h. It was concluded that PDLCs had good biocompatibility with cpTi, and showed a regular and dynamic pattern in the process of attaching to cpTi.

BACKGROUND:Hereditary factor occupies a certain position in suicidal behavior of depression. The researches in the past are focused on the hereditary effect on bipolar depression suicide.How do hereditary patterns and effects work in suicidal behavior in unipolar depression?OBJECTIVE: To probe into hereditary patterns and effects on suicidal behavior in unipolar depression.DESIGN:Retrospective investigation.SETTING:A municipal psychiatric hygienic centerPARTICIPANTS:Unipolar depression group included 115 outpatients and inpatients diagnosed in Wuxi Psychiatric Hygienic Center from June 1st 1983 to May 31st 2002.The diagnosis tallied with Standards on Depression Onset in Categories and Diagnostic Standards on Psychiatric Disturbance in China of 3rd Edition and with Standards on Severe Depression Onset in Manual of Diagnosis and Statistics of Psychiatric Disturbance in America of 4th Edition.The attack frequency of all the cases ≥ 3 times or the cases had been relieved ≥8 years after a couple of attacks.METHODS:The patients who tallied with the standards on unipolar depression received the investigation in every family tree under the instruction of 2 physicians-in-charge and more than 2 physicians and filled up the self-made investigation form of psychiatric family tree,including mainly the data of social demography of patients and their first grade relatives,characters of disease onset,frequency of attack,history of treatment and suicide. After re-diagnosed by 2 physicians-incharge and more than 2 physicians and checked by one physician-incharge,the cases were collected in patient group. The interview was carried on for the patients with suicidal behavior among all of the survived patients (107 cases) and first grade relatives (14 cases).The interview (337 cases) and investigation with letter (380 cases) were carried on for the first grade relatives without suicidal behavior. The investigation forms of 13 dead cases (8 cases of patients, 5 cases of first-grade relatives) were provided and filled-up by one or two first grade relatives. Two researchers interviewed the cases in the control,inquired the first grade relatives and filled up the investigation form of family tree.Single factor analysis was used for all the data and Falconer pattern of polygenetic threshold-value theory was used to estimate hereditary rate and standard error in suicidal behavior.Separation analysis in medical hereditary mathematic method and polygenetic threshold-value theory were applied to discuss the hereditary patterns.MAIN OUTCOME MEASURES:Hereditary effects and patterns of suicidal behavior in unipolar depressed patients.RESULTS:Suicidal risk of unipolar depressed patients(51.30%,59/115)was higher than their first grade relatives (2.58%,19/736) (x2=283.16,P ＜ 0.01).Suicidal risk of the first grade relatives (2.58%,19/736) of unipolar depressed patients was higher than the control (0.12%,3/2469)(x2=50.36,P ＜ 0.01).Suicidal risk of the first grade relatives of the patients with suicidal behavior (3.8%,14/372) was higher than that of the first grade relatives of the patients without suicidal behavior (1.4%,5/363)(x2=4.14,P＜ 0.05).The weighted average hereditary rate and standard error was (70.16±0.79)% for suicidal behavior in unipolar depression.The predictive morbidity of suicidal behavior in the first grade relatives was 3.1% and the real morbidity was 2.6%,which did not indicate significant difference (u =0.766, P ＞ 0.05).CONCLUSION:Suicidal behavior of unipolar depression presents obvious hereditary effects and its hereditary patterns tally with polygenetic inheritance.

Objective:To investigate the acceptance of advance care planning and its influencing factors in heart failure patients.Methods:A total of 208 patients with heart failure were surveyed by general data questionnaires and advance care planning acceptance questionnaires.Results:The total score of advance care planning acceptance of heart failure patients was (44.26 ± 11.73), the score of feeling dimension was (13.67 ± 5.72), the score of attitude dimension was (30.59 ± 6.33). 53.4%(111/208) of patients were willing to accept the talking about advance care planning. Regression analysis results showed that education level, New York Heart Association (NYHA) classification, communication status with medical staff and whether they had received life-sustaining treatment were important factors influencing of the acceptance of advance care planning in patients with heart failure.Conclusion:Patients with heart failure had higher acceptance of advance care planning. In clinical work, it is necessary to strengthen the scientific popularization of advance care planning in patients with low education level, low NYHA grade and no exposure to life-sustaining treatment. And strengthen the daily communication with patients to prepare for the follow-up advance care planning related communication.

In order to investigate the expression of cyclooxygenase-2 (COX-2) in human lower segments of myometrium obtained from women in labor and those not in labor and identify the splicing variant of COX-2, reverse transcriptase-polymerase chain reaction (RT-PCR) was used to detect the expression of COX-2. The primers were designed and synthesized according to the sequence of rat COX-2 splice variant which was discovered firstly by us. Then the splicing variant of COX-2 in human myometrium from woman in labor was identified, cloned into vector and sequenced. The results showed that the expression of COX-2 mRNA was lower in human myometrium obtained from women who were not in labor than that in labor women and a new band of COX-2 was obtained in myometrium from labor woman. The fragment included an unspliced intron, which pitched between exons 7 and 8. It was suggested that COX-2 gene was not only expressed highly in human myometrium from woman in labor, but also produced splicing variant by alternative splicing.

Depression is a common psychiatric disorder characterized by low mood with complex pathophysiological mechanisms and poor effect of pharmacological treatment.The animals were placed in greater sensory, physical and/or social stimuli than those of the standard feeding environment, so that they can obtain positive plasticity and adaptability.Environmental enrichment(EE) is a common intervention to improve brain function in laboratory.A large number of studies have shown that EE had significant ameliorative effects on various animal models of depression, but the mechanisms have not been yet fully understood with outcome heterogeneity in ethology.There was no universally accepted and unified paradigm and standard for EE due to its multi-dimensionality and complexity.Therefore, it is necessary to improve the structural components and implementation steps of EE by integrating the existing data.Combined with recent studies on animal models of depression, this paper reviewed the anti-depression mechanism of EE from promoting hippocampal neurogenesis, reducing neuroinflammation, regulating neuroendocrine and affecting epigenetic modifications, in order to provide new ideas for mechanisms research and treatment of depression.As the rise of precision medicine and individualized medicine brings human growing interest in exploring the sources and mechanisms of inter-individual differences and intra-group effects of depression, it will be a challenge to translate EE to the human society in a rational way.
