Objective: To observe the clinical efficacy and differences of the Zhuyu Juanbi formula delivered through ultrasound at Zusanli on patients with chemotherapy-induced peripheral neuropathy (CIPN) due to paclitaxel injection. Methods: A total of 72 breast cancer patients with CIPN were randomly divided into two groups. The treatment group (36 cases) was treated with oral methylcobalamin plus ultrasonic medicine permeating Zhuyu Juanbi formulae, while the control group (36 cases) was treated with oral methylcobalamin alone. Following two 2 cycles of continuous treatment, the efficacy of peripheral neurotoxicity, TCM syndrome score, FACT/GOG-Ntx score, total neuropathy score, and safety indicators of gynecological cancer patients were observed in the two groups. Result: In the treatment of CIPN, the addition of ultrasonic medicine permeating Zhuyu Juanbi formulae was more effective than oral methylcobalamin alone in reducing peripheral neurotoxicity and improving the quality of life of patients. The difference between the two groups was statistically significant (P < 0.05), and ultrasound drug penetration Zhuyu Juanbi formulae significantly reduced the FACT/ GOG-Ntx score and TNS score in the treatment group. In terms of drug safety, it rarely caused adverse reactions such as grade 3 and 4 leukopenia, and the safety profile was therefore good. Conclusion: The combination of ultrasonic medicine permeating Zhuyu Juanbi formulae and methylcobalamin has been demonstrated to be an effective treatment for peripheral neurotoxicity in patients with PIPN. It has been shown to significantly improve the clinical symptoms of PIPN patients, improve the quality of life of patients, and have a good safety profile. 展开更多

The first is gravity, the second is the Doppler’s effect and the third is the Compton scattering. The red shift of cosmology is considered to be caused by the receding motions of celestial bodies, of which essence is the Doppler’s effect. However, the basic formula used to calculate the relationship between red shift and distance for Ia supernova in cosmology is z+1= R(t0)/R(t1)which is based on the R-W metric and related to the scalar factor R(t). This is different from the Doppler formula which is related to speed factor R(t). Because the R-W metric is only a mathematical structure of space, the metric red shift is not an independent law of physics, this inconsistence is not allowed in physics. It is proved strictly in this paper that the formula of metric red shift is only the result of the first order approximation. If higher order approximations are considered, we can obtain a restrict condition R(t). It indicates that if the formula of metric red shift holds, it can only be suitable to describe the spatial uniform expansion, unsuitable for the practical universal process with acceleration. The further study reveals that the R-W metric violates the invariability principle of light’s speed in vacuum. The time delay caused by 展开更多

The first is gravity which is related to mass. The second is the Compton scattering which is related to the energy transformation of photon. The third is the Doppler’s effect which is related to velocity. The basic formula used to calculate the relation of red shift and distance of Ia supernova in cosmology is which is related to the scalar factor of the R-W metric. It is completely different from the Doppler formula of red shift which is related to velocity factor . This kind of inconsistency is not allowed in physics. Because of , when became larger and larger with time increase, z became smaller and smaller, means that space expansion leads to red shift becoming smaller. At present time, we have and , means that there is no red shift for the light emitted from distance celestial bodies at present. The results obviously violate the Hubble law! It is proved strictly in mathematics that the formula is untenable unless constant and . The further study reveals that the essential reason of the mistake is that the R-W metric violates the principle of light’s speed invariable. The time delay caused by relativity velocity between light’s source and observer is neglected. Besides, there exists the problem of time misalignment between theoretical calculation and practical observations in the original documents of Ia supernova projects. So the formula used to calculate the relation between red shift and distance of Ia supernova is wrong and the deduced conclusion about dark energy and the accelerating expansion of the universe are incredible. It is proved in this paper that based on the Doppler’s formula and the method of numerical calculation, the relation of red shift and distance of Ia supernova can be explained well. The hypotheses of dark energy and the accelerating expansion of the universe are completely unnecessary in cosmology. 展开更多

The objective of this paper is to derive a tentative mathematical formula of drug permeability of biodegradable membrane for implant use on the basis of Buckingham P i Theorem in principles of dimensional analysis.Such a theoretical predictive formula would be very useful for not only designing a sustained release system of drug made of biodegradable material for implant use before it is made but also for saving much time and expenses of the experiment. Three basic units were selected to describe the problem due to the invariableness of temperature under the normal physiological condition.They are mass,length and time.At first,a general mathematical formula was derived from Buckingham P i Theorem,in which the relevant parameters were placed into dimensionless Π groups.Secondly,as a special case interested to us,we gave out a predictive formula of permeability of various drugs with different molecular weights and saturated concentrations through Polylactic Acid Membrane with specified characteristics for implant use.For this end,we computed six kinds of drugs.The linear regression analysis of the relationship among these Π groups with drug permeability yielded coefficients for the corresponding Π groups.The obtained results in our paper mainly fitted in with ones obtained by the experiments under in vitro condition.Finally,a computer program for predicting drug permeability was given out in this article. 展开更多

In this paper, we use Lax-Oleinik formula to study the asymptotic behavior for the initial problem of scalar conservation law u_t + F(u)_x = 0. First, we prove a simple but useful property of Lax-Oleinik formula(Lemma 2.7). In fact, denote the Legendre transform of F(u) as L(σ), then we can prove that the quantity F(q)-′qF(q) + L(′F(q)) is a constant independent of q. As a simple application, we first give the solution of Riemann problem without using of Rankine-Hugoniot condition and entropy condition. Then we study the asymptotic behavior of the problem with some special initial data and prove that the solution contains only a single shock for t > T~*. Meanwhile, we can give the equation of the shock and an explicit value of T~*. 展开更多

We propose a regular spherically symmetric spacetime solution with three parameters in Einstein gravity coupled to nonlinear electrodynamics(NED), which describes the NED black hole with electric charge. It is found that the system enclosed by the horizon of NED spacetime satisfies the first law of thermodynamics. In order to obtain the NED spacetime with only electric charge, the case of two parameters taking the same value is considered. In this case, we express the mass of the NED spacetime as a function of the entropy and electric charge of the NED black hole, give the Smarr-like formula and the approximate Smarr formula for the mass of NED spacetime. 展开更多

BACKGROUND: How to induce endogenous neural stem cells (NSCs) to differentiate into needed neural cell types is a hot spot of current researches. OBJECTIVE: To compare differences between fetal bovine serum and Chinese herbal formula Naoluoxintong serum supplementation for inducing proliferation and differentiation in rat embryonic NSCs. DESIGN, TIME AND SETTING: An in vitro, serum pharmacology, comparative, observation study was performed from March to September in 2008 at the Laboratory of Neurodegenerative Diseases, College of Life Science in University of Science and Technology of China, the Key Laboratory Breeding Base of Acupuncture Foundation and Technology in Anhui University of Traditional Chinese Medicine, the Anhui Province Key Laboratory of R & D of Chinese Medicine, and at the Level 3 Laboratory of Molecular Biology of the State Administration of Traditional Chinese Medicine. MATERIALS: The Chinese herbal formula Naoluoxintong was produced by Radix Astragali, Radix Notoginseng, Rhizoma Chuanxiong, Scolopendra at Anhui University of Traditional Chinese Medicine. Mouse anti-rat nestin, gliat fibrillary acidic protein, and galactocerebroside monoclonal antibodies, as well as rabbit anti-neuron-specific enolase polyclonal antibody were produced by Chemicon, Billerica, MA, USA. METHODS: Wistar rats aged 3 months were intragastrically infused with Naoluoxintong. Wistar rat embryonic NSCs (passage 8) were induced to proliferate and differentiate using 10% fetal bovine serum, 10% Naoluoxintong serum, and 10% rat serum. MAIN OUTCOME MEASURES: Phenotypic changes in cultured cells were detected using phase contrast microscopy, and cell proliferation and differentiation were observed using immunofluorescence staining. RESULTS: Proliferation and differentiation of embryonic NSCs was induced by three different types of blood serum. Although the differentiation time course with Nao/uoxintongserum was later than with the other two methods, the differentiated cells were morphologically similar to mature neurons to a greater extent. CONCLUSION: Nao/uoxintong serum supplementation induced differentiation of NSCs into neuronal-like cells and stimulated neuronal maturation. 展开更多

Objective To study the drug effects of "Caulis Sargentodoxae Formula" which dears away heat and blood clot on experimental endometriosis in rat, and to compare this effect with Danazol's effects. Method The model of endometriosis rat was induced by transplanting with endometrium surgically The rats were divided into 6 groups randomly: the non-treatment group, the castrate group, Danazol group(80 mg/kg), "Caulis Sargentodoxae Formula" group (110 g/kg), the medium dose group(77.5 g/kg) and the low dose group(55 g/kg).
