Patients with uremia often develop bleeding diatheses at cutaneous or incisional sites, intra-abdominal or intracranial hemorrhages. We report active bleeding in a uremic patient after she received a temporary catheter for hemodialysis therapy. Active bleeding was considered to be due to platelet dysfunction, diagnosed by prolonged skin bleeding time. Her spontaneous bleeding gradually vanished after receiving blood transfusions with cryoprecipitate. The assessment of skin bleeding time in uremic patients with active bleeding is a crucial step to identify platelet dysfunction.

Based on the analysis of the absorption spectrum of dried object and the radiation spectrum of heater, the concept of Matching Absorption Degree in Whole Wavelength Region (MADWWR) and its design optimization method are put forward. The corresponding mathematical model is established. Taking soft-base coat drying for example, design optimization of MADWWR is carried out in different temperatures. The optimal values of MADWWR and surface temperature of heater are obtained. The effectiveness of the results is verified by the engineering example. The calculation method and the corresponding calculation program of optimal matching degree are universal, which can provide useful guidelines for the energy-saving design of infrared heating and drying.

According to the characteristics and difficulties of the soft-base coat drying, the approach of solving the temperature sensitivity through the furnace type structure design as well as the mechanical and electrical chain design is put forward. The form of the infrared radiation field used for soft-base coat drying is determined. By analyzing the characteristics of the infrared heating element and its reflection equipment, a mathematical model of radiation is proposed, and by using of the results and programs obtained from the model, the scientific design method of infrared radiation field is presented. The problem of requirements for uniform temperature of the soft-base coat is solved by infrared radiation field design and movement of belt. By taking the energy saving reconstruction of an infrared blast furnace as an instance, the effectiveness of the proposed method is verified. The design method not only has guiding significance to the design of soft-base coat infrared drying, but also has reference value to other types of infrared heating design for energy saving .

The effect of ketanserin at 5 mg, 10 mg and 20 mg twice daily for 3 months was studied in Chinese patients with hypertension. Both 10 mg and 20 mg doses twice daily effectively reduced systolic and diastolic pressures, while 5 mg twice daily was not effective. The 20 mg regimen was more effective than 10 mg in reducing diastolic, but not systolic pressures. Blood pressure reduction was progressive up to 1 month of treatment but not thereafter. Neither first-dose hypotension nor postural hypotension were seen. There were no effects on body weight or heart rate. A nominally significant 6 msec increase in QTc was seen with 10 mg, but not with 5 or 20 mg twice daily; this could be a chance finding. The side-effect burden was light, and decreased with time.
