If it is mild, the patient can recover without receiving any treatment. But, in case the attack lasts long, the patient suffers a lot, and needs to be treated in time. In recent years, the author has treated 60 cases of hiccup by puncturing points lateral to Haiquan (EX-HN11) with satisfactory results, which is reported as follows.展开更多

It is the view of the authors that accumulation of heat and dampness in the heart and stomach and deficiency of both spleen and kidney with blood stasis would be the main predisposing factors in pathogenesis of incipient diabetic nephropathy. A controlled clinical study of 32 patients treatment with modified recipe of Wang Kentang’s Bai Fu Ling Wan, a proved formula of clearing away the stomach-heat, purging the heart fire, strengthening the stomach and tonifying the kidney, and simultaneously resolving blood stasis and turbid qi was performed. The total effective rate was 93.8%, superior to that in the control group treated with Capoton (59.9%). A marked improvement in symptoms, control of blood glucose level and reduction of urinary protein obtained in the treatment group suggests that this treatment is effective in retarding the development of the disease.展开更多

The results showed that the total effective rate for audition elevation in the treatment group was 52.0%, and that in the control group, 26.1%. In the treatment group, the rheological indexes were improved after treatment, the difference being very significant in comparison with those before treatment (P<0.05 and P<0.01); while in the control group, except the whole blood low shearing specific viscosity, all the other 4 indexes were not statistically significant before and after treatment (P>0.05).展开更多

The property of corrosion resistance dual-implanted (C+Ti) H13 steel is studied using multi-sweep cyclic voltammetry. TEM images of the cross section of an implanted sample reveal plenty of circular nanometer structures with diameters of 10–30 nm. The phases are densely embedded in the implanted layer. The embedded structure improves the surface corrosion resistance, as can be observed with a scanning electron microscope (SEM). The phases with the shape of a tiny wire in nanometer size are formed. The nanometer phases, consisting of TiC, FeTi and FeTi2, are formed in dual implanted layer. The corrosion current peak density decreases to 1/16–1/10 that of the unimplanted H13 steel. The formation conditions of the nanometer phases and their effects are investigated. The passivation layer consists of nanometer phases. The corrosion resistance of the dual implantation can be further enhanced with an increase in ion dose.展开更多
