Objective To observe whether recent sexual intercourse might cause microscopic hematuria, and investigate the cause of hematuria. Methods Eighty healthy volunteers (40 men and 40 women) consented to have intercourse with their married couples and provide samples of urine for testing before intercourse and the first day morning, noon, evening and the second day morning after intercourse. After appropriate instruction, volunteers tested their own urine for the presence of blood using standard dipsticks. Any volunteer with hematuria after intercourse was offered a comprehensive hematuria assessment and followed-up for two years. Results None of the volunteers had positive hematuria before sexual intercourse. 9 of the 40 women, but no men, had positive hematuria at the first day morning after intercourse, and 3 of the nine patients with hematuria still had positive hematuria at the noon of the first day. Five women of 9 patients with hematuria accepted two years follow-up and no abnormal was identified. Conclusion It suggested that recent sexual intercourse was a cause of asymptomatic microscopic hematuria in women, and a history of recent sexual intercourse should be considered when assessing the clinical significance of microscopic hematuria in women.

35 patients with malignant lymphoma and 18 patients with multiple mycloma were investigated for expression of OKT10in pherpheral blood. A significant incresing of OKT 10 positive cells was found in most of patients (26/30, 16/18 cases respectively) with Non-Hodgekin's Lymphoma(NIIL) and Multiple myeloma(MM). The inereasing of OKT10 positive cells is related to the degrce of malignaency of patients with NIIL from low-grade to high-wade. No relationship between serum beta-2-microglobulin and OKT10 positive cells in patients with NIIL and MM was also found.

To determine the effect of pre-operative chemotherapy on apoptosis in breast cancer and to evaluate its signif icance as a prcgnostic marker. MethodsPatients with breast cancer were divided into preoperative chemotherapy group (40 cases)and control group (42 cases). Two groups were analyzed for the appearance of apoptosis by using TUNEL method and electron mi croscope in tissue sections. ResultsApoptosis occurred in 92.5 % of preoperative chemotherapy group and in 78.5 % of control group. The apoptotic indexes were 19.37 + 6.49 and 9.26 + 5.04 ( P < 0.01 ) respectively. Low apoptotic index was related to disease-free survival of patients with breast cancer (P < 0.01 ). ConclusionThe preoperative chemotherapy can induce apoptcsis of breast cancer and improve disease-free survival.

Agmatine was first identified and characterized as a candidate for CDS (clonidine displacing substance) in the bovine brain in 1994. The following researches demonstrated that agmatine was a widely distributed endogenous substance and performed a lot of biological functions in the central nervous system. The evidences revealed its targets were diverse and its mechanisms were complicated. Now it is well accepted that agmatine is a new neurotransmitter and/or neuromodulator and it might be an endogenous ligand of imidazoline receptor.
