The effects of hemorrhagic shock on the platelet functions in non-heparinized rabbits were studied. It was found that the platelet adhesiveness and aggregation and the pasma level of serum serotonin and throraboxane B2 significantly increased in the early period of hemorrhagic shock. Thereafter, as the shock was progressing, the platelet adhesiveness and aggregation were gradually inhibited while plasma level of serotonin and thromboxane B2 increased further and reached the peak in the 3rd hour after the onset of shock.The results indicated that the release of vasoactive substances such as serotonin and thromboxane after the activation of platelets seems to play a more important role than platelet adhesion and aggregation in the pathogenesis of hemorrhagic shock.

Based on the existing Electronic Medical Records (EMR) system in Shanxi Dati Hospital,the paper analyzes the consultation process,and illustrates the inter-department consultation electronic process based on existing EMR system from the four roles of doctors in application department,nurses in application department,nurses in consultation department and doctors in consultation department,introduces the involved function modles concretely.

The effects of thyrotrophin releasing hormone(TRH) given 0.5h after injury on survival and ?-endorphin release in scalded rats (about 30% TBSA, 20s in 100℃ water) were studied. The results showed tenfold increase of ?-endorphin-like immunoreactivity (ir-?-EP) in the plasma and the pituitary 2h after scald, while in the hypothalamus ir-?-EP did not rise above control until 6h after scald. 24h after scald, survival in rats given TRH was 46.7% and those given saline was 6.7% (P

Objective To detect ?-nerve growth factor(?NGF) secreted by hair follicle bulge cells cultured in vitro qualitatively and quantitively and search the relationship between ?-NGF and bulge cells growth condition.Methods The primary tissues from the labial part and around the barbell in inbred Wistar rats aged 6-8 d were stripped by micromanipulative technique and cultured.The ultrastructure of primary bulge cells was observed under transmission electron microscope(TEM).The secretion of ?-NGF was determined by ELISA and immunocytochemistry.Results Primary bulge cells were cultured in vitro successfully.?-NGF was strongly expressed in the plasma of cultured bulge cells detected by ICC.The secretion of NGF detected by ELISA was regularly correlated with the characteristic of primary cultured bulge cells.Conclusion Primary bulge cells secreted the highest ?-NGF when bulge cells grew into peak phase.The expression of ?-NGF must have some necessary relationships with hair follicle bulge cells.

Objective:To study the role of the ligament of Marshall in atrial fibrillation arising at pulmonary veins. Methods:20 mongrel dogs were randomly divided into two groups(10 dogs in each group). Paroxysmal atrial fibrillation arising at the pulmonary veins was built in all dogs. After Ligament of Marshall ablation in group1,pulmonary vein ablation was performed in both group1 and 2. Epicardial electrograms,effective refractory period,and atrial inducibility were analyzed before and after two ablations. Results:The activation cycle length slowed down and atrial fibrillation inducibility was significantly decreased after the ligament of Marshall ablation in group1;atrial fibrillation inducibility were both decreased after pulmonary vein ablation. Conclusion:Ligament of Marshall might serve a electrical connections between pulmonary vein and left atrium or be another source of rapid activations in atrial fibrillation arising at the pulmonary veins.

Genital ulcer disease is a common presentation of sexually transmitted infections (STIs) and can cause significant morbidity in patients. Syphilis (chancre of primary syphilis) and genital herpes are the two most significant ulcerative STIs and are occasionally indistinguishable clinically. Infectious syphilis is on the rise in Singapore particularly in men who have sex with men (MSM); whilst genital herpes although showing a decreasing incidence in recent years still presents with more than 500 notifications a year as first episode genital herpes. Due to the breaks in the mucosa of the skin caused by the ulcers, the risk of acquisition as well as transmission of HIV infection are both increased making timely treatment of genital ulcers of utmost importance. Although uncommon in Singapore, chancroid, LGV and granuloma inguinale remain endemic in some parts of Asia and there should be a high index of suspicion for patients who have returned from these regions presenting with ulcerative lesions. All patients who present with genital ulcers should have their blood tested for syphilis and HIV as well as a swab for culture or PCR testing taken from the ulcer to exclude genital herpes.

The most informed members from 907 households were interviewed in regard to the hospital bursar. Results show that the majority of population (in which 7.5% with high income, 70.1%-mean and 22.4% - low income) is capable to pay the bursar by various resources including the available fund 65.2%, the sale of domestic animals and commodities 6.3% and the debt 27.2%. For all population, hospital fee is acceptable but on which the awareness is insufficient. Recommendations were made concerning the exemption for the subjects with low-income.
