BACKGROUND: Cardiac function of patients with hypertension is impaired to various extents. How does the impairment level of cardiac function of patients with hypertension differ at various stages?OBJECTIVE: To observe cardiac function of patients with hypertension at various stages and compare the indexes with those of healthy people.DESIGN: Case-control and comparative observation.SETTING: Department of Special Treatment, General Hospital of Shenyang Military Area Command of the Chinese PLA.PARTICIPANTS: Totally 100 patients with hypertension were selected from the Internal Medicine Department of General Hospital of Shenyang Military Area Command of the Chinese PLA between October 2002 and May 2003. Among them, 30 cases of hypertension were at stage Ⅰ , 40 at stage Ⅱ and 30 at stage Ⅲ. At the same time period another 30 healthy people were selected as the control group. All the subjects signed the informed consent.METHODS: Cardiac function of the included subjects were detected with XJS-Ⅰ cardiac function testing equipment. Patients were tested at supine position and electrode was put on the basis of four-probe method.Breath was held at the end of expiration; meanwhile, lead electrocardiograph Ⅰ, cardiophonogram, cardiac admittance differential coefficient method and beating of carotid artery were recorded. Various indexes were processed with the computer. Detected indexes were heart rate, ejection prophase, ejection time of left ventricle, ejection prophase/ejection time of left ventricle, delay time of electro-machine, isovolumetric contraction time, isovolumetric contraction time/ejection time of left ventricle, time of pulse wave transmission, stroke volume, cardiac output, cardiac index,stress index of myocardial contraction, total peripheral resistance, and vascular compliance.MAIN OUTCOME MEASURES: Comparison of cardiac function between hypertensive patients at various stages and healthy people.RESULTS: All the 100 patients with primary hypertension and 30healthy people entered the final analysis. [1] Ejection prophase, isovolumetric contraction time, peripheral resistance, ejection prophase/ejection time of left ventricle and isovolumetric contraction time/ejection time of left ventricle: Those of hypertensive patients were obviously longer or stronger than those of the healthy subjects (P ＜ 0.01); those of patients with hypertension at stages Ⅱ and Ⅲ were obviously longer or stronger than those of patients with hypertension at stage Ⅰ (P ＜ 0.01). [2] Stroke volume, cardiac output, stress index of myocardial contraction, vascular compliance, time of pulse wave transmission and cardiac index: Those of hypertensive patients were obviously shorter or weaker than those of the healthy subjects (P ＜ 0.01); those of patients with hypertension at stages Ⅱ and Ⅲ were obviously shorter or weaker than those of patients with hypertension at stage Ⅰ (P ＜ 0.01). Among the indexes mentioned above, vascular total peripheral resistance of hypertensive patients at stage Ⅲ was obviously stronger than that of hypertensive patients at stage Ⅱ (P ＜ 0.05),but vascular compliance of the latter ones was obviously than that of the former ones (P ＜ 0.05).CONCLUSION: Cardiac function of patients with hypertension is decreased as compared with that of healthy people, and tends to further decrease with the development of hypertensive condition.

Objective To detect the effect of the antiphospholipid antibodies on the Schwann cells in vitro and to find if the Extract of Ginkgo biloba 761(EGb761)has any protective effects.Methods The immunoglobulins(Ig)were extracted from the serum of the patient with autoimmune polyneuropathies and those with controls.Ig only or Ig plus calf serum(served as complement)were added into the culture solutions of the Schwann cells.The density of the cell in one high power field,the cell perimeter and area were detected and compared to those blank and those controls.Results The shape of the Schwann cells in both the Ig and Ig plus calf serum solution were greatly changed.The densities of the cells in them were both lower than the blank ones,with more severe in the cells with calf serum.There was no significant different between the solutions with or without EGb761.Conclusion Ig from the patients with autoimmune polyneuropathies could attack the Schwann cells in vitro,with the existence of complements,the destruction was even more severe.No protection of EGb761 could be found in these situations.

Traditional medicine (herb medicine) began to prevail again over last two decades, and it is about 70% of the world population taking herb medicine as supplement or alternative medicine according to a recent survey. The consumption of herb medicine increased exponentially in Canada, Australia and Europe during last 10 years. Since concomitant administration of herbal and western medicine has become a trend, it requires paying close attention to the problem. Herb-drug interactions have been extensively investigated worldwide, and there is an increasing concern about the clinical herb-drug interaction. In this review we introduced the current progress in the herb-drug interactions including evidence-based clinical studies and establishment of levels of evidence for herb-drug interaction; and in the related mechanisms including the induction and inhibition of metabolic enzymes, inhibition and induction of transport and efflux proteins, alteration of gastrointestinal functions, and alteration in renal elimination. We also analyzed both the achievements and the challenges faced in the concomitant administration of traditional Chinese medicine and western medicine.

OBJECTIVETo explore the expression of the epithelial cell adhesion molecule (EpCAM) in prostate cancer (PCa) and its clinical significance.

METHODSWe collected tissue samples from 63 cases of PCa, 46 cases of prostatic intraepithelial neoplasia (PIN), and 58 cases of benign prostatic hyperplasia (BPH) adjacent to PCa and determined the expression of EpCAM in the epithelial and stromal cells by immunohistochemistry.

RESULTSThe positive expression rates of EpCAM in the epithelial cells were significantly higher in PCa and PIN than in PCa-adjacent BPH (98. 4 and 97. 8 vs 51.7%, P <0. 01), and so was that in the stromal cells of PCa than in those of PCa-adjacent PIN (89.5 vs 50.0%, P <0.01). The expression of EpCAM.was remarkably higher in the stromal cells of bone metastasis than in those of non-bone metastasis tissue (100. 0 vs 40. 0%, P <0. 01) but showed no statistically significant differences between the highly and poorly differentiated PCa tissues (88.5 vs 91.9%, P >0.05).

CONCLUSIONThe expression level of EpCAM in the stromal cells of PCa is related to the occurrence, progression, and bone metastasis of the tumor, and therefore may be used as a marker in the early diagnosis of PCa as well as a predictor of bone metastasis of the tumor.
