Objective To explore the value of vascular endothelial growth factor(VEGF) in predicting and mornitoring ovarian hyper-stimulation syndrome(OHSS). Methods 11 cases of OHSS patients and 16 cases of high-responder patients were enrolled in this study, respectively from IVF-ET or ICSI programme. Serum VEGF level before giving gonadotrophin, on the days of hCG administration, OPU and ET, and at the 7th and 14th days after ET as well as the VEGF level of follicular fluid (FF) on the day of OPU were measured. The serum VEGF of hospitalized women with severe OHSS were also measured during the whole therapy. Results Compared with high-responder patients, serum VEGF level on mid luteal and late luteal phases significantly increased in OHSS patients, and FF VEGF level obviously increased as well. Serum VEGF level gradually decreased along with clinical and biological improvement of OHSS. Conclusion FF VEGF level could predict the occurrence of OHSS, and serum VEGF level could monitor the progress of OHSS.

Objective To explore the current status of physical exercises of patients with primary hypertension and provide basis for selective nursing intervention. Methods Investigation was carried out in 238 patients patients with primary hypertension in a third-grade and first-class hospital in Guangzhou on their physical exercises using the theory of "periodic behavior changing model". The results were ana|yzed. Results Patients who didn't plan to take physical exercises account for 19.3%,who planned to take it was 15.1%,who prepared to take it was 20.2%,who were taking it was 8.8% and who were maintaining it was 36.6%.The age and duration of illness course significantly influence the distribution of taking exercises in different stages, P<0.05.While gender and education background were not important influencing factors. Conclusion We should pay attention to increase the recognition of patients with primary hypertension to take physical exercises autonomously,especially the young and middle-aged patients.

P-selectin is also known as CD62. It promotes the occurrence of ischemic cerebrovascular disease by mediating the activation of endothelial cells and platelets as well as the processes of the formation and development of atherogenesis. A number of studies have confirmed that P-selectin plays important roles in the occurrence and development of the risk factors (such as hypertension, diabetes, hypercholesterolemia, heart disease, smoking, alcohol abuse and hyperfibrinogenemia) for ischemic cerebrovascular disease. It remains to be confirmed by further studies whether P-selectin can be used as an independent risk factor for predicting the occurrence of ischemic cerebrovascular disease.

Both basic and clinical studies have confirmed that inflammatory response plays an important role in the occurrence and development of atherosclerosis (AS) as well as its caused clinical events.The aggregation phenomena of T lymphocytes,macrophages and dendritic cells (DCs) can be observed in intima and atherosclerotic plaques in the event of atherosclerosis.As the most important antigen-presenting cells activating T lymphocytes,DCs have the important functions of determining T lymphocyte activation,apoptosis,and aggregation.This article reviews the correlation between DCs and atherosclerotic lesions.

Through the discussion on TCM physiological characters of females in follicular, ovulatory, luteal and menstrual phases and treatment principles, the clinical application of artificial cycle therapy of acupuncture and moxibustion was introduced for irregular menstruation and the typical cases were attached. It is suggested that the menstrual cycle follows the growth-consumption rule of yin, yang, qi and blood. The corresponding treatment principles should be applied in accordance with the change rule of menstrual cycle. Hence, it is worth to adopt the artificial cycle therapy of acupuncture and moxibustion for irregular menstruation in clinical application.

Objective To investigate the effects of Qinma Formula on endogenous anti-inflammatory system in rats with chronic obstructive pulmonary disease (COPD); To discuss its mechanism of action. Methods Rat models of COPD were made by modified smoked lipopolysaccharide method. 70 healthy SPF male Wistar rats were randomly divided into normal group, model group, Western medicine control group (aminophylline group), TCM medicine control group (Liujunzi Decoction group) and Qinma Formula high-, medium-, and low-dose groups, with 10 rats in each group. Each medication group was given relevant medicine for gavage. The pathological changes of lung tissue were observed under light microscope; the alveolar lavage fluid (BALF) and venous blood were collected and the related indexes were tested; the levels of serum IL-1β, IL-6 and IL-10 were detected by ELISA. Results Compared with normal group, BALF white blood cells, neutrophils, macrophages, lymphocyte, hemoglobin and platelet count in rats of model group increased significantly (P<0.05). Compared with the model group, BALF white blood cells, neutrophils, and macrophages in rats of Qinma medium- and high-dose groups and Liujunzi Decoction group decreased significantly (P<0.05); white blood cells, hemoglobin, and platelet count in rats of Qinma medium-, high-dose groups and aminophylline group decreased significantly (P<0.05); levels of IL-1β and IL-6 in serum decreased significantly (P<0.05); level of IL-10 in serum increased significantly (P<0.05). Conclusion Qinma Formula can effectively inhibit the inflammatory response through the regulation of inflammatory response-related cytokines.

Objective To investigate the changes of follicular regulatory T cells ( Tfr cells) and follicular T helper cells ( Tfh cells) in peripheral blood of children with myasthenia gravis ( MG) . Methods We recruited 28 MG patients and 20 healthy subjects in this study. The percentages of Tfh and Tfr cells in peripheral blood samples were measured by flow cytometry. Real-time PCR was performed to detect the ex-pression of transcription factors and regulatory factors of Bcl-6, c-MAF, Blimp-1 and PD-1 at mRNA level. ELISA was used to detect the levels of IL-2, IL-6, IL-10 and IL-21 in plasma samples and the titers of Ach-Rab and PsMab. Results Compared with the healthy subjects, the MG patients showed higher percentages of Tfh cells and lower percentages of Tfr cells before receiving treatment. The expression of Bcl-6 and c-MAF on CD4+T lymphocytes cells at transcriptional level were significantly enhanced, while the expression of Blimp-1 on CD4+T cells and the expression of PD-1 on Treg cells at transcriptional level were inhibited in the MG patients in comparison with those in healthy subjects. Moreover, decreased levels of IL-2 and increased levels of IL-21 were found in plasma samples collected from the MG patients. Conclusion The decreased percentages of Tfr cells and increased percentages of Tfh cells in patients with MG resulted in abnormal ratios of Tfr/Tfh cells, which might be involved in the immunological pathogenesis of MG. Several changes in the patients with MG might be responsible for the imbalanced ratio of Tfr/Tfh cells, which included changes of IL-2 and IL-21 in microenvironment, enhanced expression of Bcl-6 and c-MAF at mRNA level and inhibited expression of Blimp-1 at mRNA level on CD4+T cells as well as over-expression of PD-1 at mRNA level on Treg cells.

The adhesion of leukocytes to vascular endothelium is crucial for the generation of inflammatory responses. The selectins and ?2-integrin (Mac-1) play a major role in the process. Recently, it was reported that RO-heparin can inhibit selectin-mediated leukocyte adhesion. The effect of RO-heparin on the Mac-1-mediated neutrophils adhesion were further tested. The results showed that RO-heparin could effectively inhibit neutrophils binding to ICAM-1, adhering to COS-7 cells expressing human ICAM-1, and adhering to human umbilical vein endothelial cells (HUVECs) under static and flow conditions. The findings suggest that the effect of RO-heparin on leukocyte adhesion is mainly due to its inhibition on the interaction between selectins or Mac-1 and their ligands and that RO-heparin might be useful in preventing inflammation diseases.
