The interactions between blood cells and blood cells or blood cells and endothelium of blood vessel are mainly mediated by adhesion molecules. The role of adhesion molecules is diverse in vivo, which involved in adhesion, migration, differentiation and signal transduction of blood cells. The function of adhesion molecules is necessary to maintain the normal structure and fulfill many physiological processes of these cells. Therefore, the abnormal or deficiency of their expression and function will disrupts normal physiological processes and results in clinical disease. In this paper, several generic classes of adhesion molecules, including the integrins, the selectins, the immunoglobulin superfamily and others are introduced, and a lot of related physiopathological status, such as inflammation, hemostasis, arteriosclerosis, thrombosis and stem cell homing are discussed. The studies on the adhesion molecules of blood cells will contribute not only to understand the pathogenesis of some disorders, but also to search new targets in diagnosis and treatment of these diseases.

Objective To research in the effect of pertinent nursing method on therapeutic effect of postoperative intractable affective disorder. Methods We drew out all the patients who were in accordance with inclusion and exclusion criteria and accepted surgical treatment from June to September in 2008,and obtained 45 patients which were divided into the experimental group(21 participants) and the control group (24 participants) randomly.The experimental group adopted pertinent nmsing intervention in different periods,the control group accepted routine nursing measures.Two psychiatrists evaluated these patients' symptoms using the Brief Psychiatric Rating Scale (BPRS), Bech-Rafaelsen Mania Rating Scale (BRMS), and Hamilton Depression Scale (HAMD). Results The difference of total efficiency between the two groups had no statistical significance at 1 week and 1 month after operation, yet, obvious statistical significance was seen on 3 and 6 months after operation.The total points of all scales had no statistical significance at 1 week and 1 month after operation; however, obvious statistical significance appeared on 3 month and 6 month after operation.The improvement of symptoms of the experimental group was better than the control group. Conclusions The nurs-i ng interventions used in this research could improve the therapeutic effect of the postoperative intractable affective disorder, and the effects were reflected mainly in the long term effectiveness.

The inheritance of famous old traditional Chinese medicine (TCM) doctors plays an essential role in the fields of TCM research. Qualitative interviews allow for subjectivity and individuality within clinical experience as well as academic ideas of doctors, making it a potential appropriate research method for inheritance of famous old TCM doctors. We summarized current situations of inheritance research on famous old TCM doctors, and then discussed the feasibility of applying qualitative interviews in inheritance of famous old TCM doctors. By combining our experience in research on inheritance of famous old TCM doctors, we gave some advice on study design, interview implementation, data transcription and analyses , and report writing, providing a reference for further relevant research.

Objective To investigate the effect of chronic stress on the expression of uncoupling protein 4 (UCP4) and Bcl-2 protein in hippocampal neurons of rat depression model.Methods Rat depression models were established by chronic unpredicted mild stress.All rats were randomly assigned to 2 groups:control group and model group.Flow cytometry was applied to detect the apoptosis rate and mitochondrial membrane potential.The level of LDH was measured by enzymes labelling instrument.The number of neurons was measured by immunohistochemistry.The expression of UCP4 and Bcl-2 protein was measured by Western blotting.Results After chronic stress,the apoptosis rate((4.35±0.19) ％)and LDH activity ((445.50±91.70) U/mg) in hippocampal tissue in the model group was significantly higher than the control group((0.34±0.06) ％,(167.20±63.40)U/mg).Compared to control group,the number of hippocampal neurons ((72.50±4.25) vs (45.30±2.54)) and the mitochon drial membrane potential decreased in the model group.The expressions of UCP4 and Bcl-2 protein in hippocampal tissue were significantly lower than the control group.Conclusion Chronic unpredicted mild stress can lead to apoptosis in rat hippocampal neurons,which is related with decline of mitochondrial membrane potential and low expression of UCP4 and Bcl-2 protein.

Objective To study the diagnosis and management of Pendred's syndrome. Methods The clinical data of 5 patients with Pendred's syndrome were analysed retrospectively. Results All patients had congenital sensorineural hearing loss and gradeⅡ-Ⅲ goiter,and 4 patients compained with thyroid nodure. Of the 5 cases, the results of perchlorate discharge test were 10%-52%. One case underwent subtotal thyroidectomy owing to misdiagnosis before the operation. All the 5 cases received thyroxine and were followed up for 4-7 years.All the patients goiter shrank and the compression symptoms relieved. Conclusions The perchlorate discharge test is the important diagnostic method and may detect the healthy carriers in the patients' relatives.Conservative treatment should be used in most patients. Patients undergoing operation owing to serious compression symptoms should be managed with thyroxine after surgery.

Interferon-tau (IFN-tau) is a newly discovered IFN of type I. It was originally found for its role as a pregnancy recognition hormone in ruminant animals such as sheep and cows. Like the other type I IFNs, IFN-tau have the same biological activities including antiviral, antiproliferative and immunomodulatory effects. In order to clearly identify the function of IFN-tau, the coding sequence of IFN-tau was amplified by PCR from IFN-tau cDNA, this fragment digested by EcoR I and BamH I and was inserted into pBV220 to form the recombinant plasmid pBV220/IFN-tau which was then transformed into E.coli BL21. It was found that pBV220/IFN-tau was highly expressed as inclusion body in BL21. Next, the expressed protein was purified on S-100 High Resolution and the purified product was confirmed by amino acid sequence analysis. Moreover, the standard antiviral activity test indicated that the activity of IFN-tau was about 2.09?106IU/ml.

Objective To evaluate the diagnosis and therapy of intestinal lymphangiectasia.Methods In this study 15 patients were admitted in our hospital during recent 7 years.Clinical manifestations included hypoalbuminemia,symmetrical edema,emaciation,diarrhea and lymphopenia.Lymphangiography,lympanscintigraphy and biopsy were performed for diagnosis.Therapy conducted included conservative therapy,low-fat and medium-chain triglycerides(MCT)diet,albumin infusions,diuretics,total parenteral nutrition and octreotide.Surgical therapy ineluded thoracic duct-vein anastomasis and segmental resection.Results In this group 8 patients receiving conservative therapy were followed-up from 1.5 to 7 years(average 2.5 years).Symptoms were alleviated in 6 patients.Seven patients underwent operative therapy,among them,4 patients received thoracic duct-exterior jugular vein anastomasis and followed-up from 1 to 5 years,with symptoms mitigated in 2 patients.3 patients underwent local intestinal resection,follow-up from 1 to 3 years found one patient was cured,one was improved,and 1 patient died 3 months afterthe operation. Conclusion Intestinal lymphangiectasia is rather rare and there was no definite and effective therapy.
