After treatment, the serum gastrin, urinary D - xylose excretory rate and T cell subgroups in patients with spleen deficiency have been greatly improved as compared with those before treatment in two groups (P< 0.01 or 0.05). Comparing the changes of the indexes between treatment group and control group, there were significant(P<0.05), or markedly significant(P<0.01) differences. It indicated that the medicinal moxibustion could improve the secreting and absorbing functions of digestive tract and the cellular immune function in patients with spleen deficiency.展开更多

Methods: A total of 150 patients with diabetic peripheral neuropathy who had received treatment in the Hospital between January 2017 and July 2018 were selected. The patients were randomly divided into two groups, with 75 cases in each group. The control group was treated with Xueshuangtong Injection and Kallikrein, and the observation group was treated with lipoic acid plus medicines given to the control group. The nerve conduction velocity, blood pressure and blood glucose, serum lipids, and serum inflammatory factors were compared between the two groups. Results: The CPT values of the median nerve-ulnar nerves, bilateral superficial peroneal nerves and deep peroneal nerves in the observation group at 5 Hz, 250 Hz, and 2000 Hz were lower than those in the control group, and the difference was statistically significant. After treatment, the SOD in the observation group was higher than that in the control group, and the MDA and Hs-CRP were lower than those in the control group, where the difference was statistically significant. After treatment, the levels of blood pressure and blood glucose in the observation group were lower than those in the control group, and the difference was statistically significant. After treatment, LDL-C, TC, and TG in the observation group were lower than those in the control group, and HDL-C was higher than that in the control group. The difference was statistically significant. Conclusion: For patients with type 2 diabetes, lipoic acid can help improve the clinical treatment, which can improve the levels of blood glucose, blood pressure and blood lipid, increase nerve conduction velocity, and reduce the damage to sensory nerve subgroup.展开更多

In the considered case, the cotorsion hull is not fully transitive and hence it is necessary to introduce a new function which differs from an indicator and assigns an infinite matrix to each element of the cotorsion hull. The relation ?difined on the set ?of these matrices is different from the relation proposed by the autor in the countable case and better discribes the lower semilattice. The use of the relation ?essentially simplifies the verification of the required properties. It is proved that the lattice of fully invariant subgroups of the group is isomorphic to the lattice of filters of the lower semilattice.展开更多

In the successive approximation theorem, we prove that, for each integer n ≥ 1, finitely many candidates for the Galois group of the nth stage of the p-class tower over F are determined by abelian type invariants of p-class groups C1pE of unramified extensions E/F with degree [E : F] = pn-1. Illustrated by the most extensive numerical results available currently, the transfer kernels (TE, F) of the p-class extensions TE, F : C1pF → C1pE from F to unramified cyclic degree-p extensions E/F are shown to be capable of narrowing down the number of contestants significantly. By determining the isomorphism type of the maximal subgroups S G of all 3-groups G with coclass cc(G) = 1, and establishing a general theorem on the connection between the p-class towers of a number field F and of an unramified abelian p-extension E/F, we are able to provide a theoretical proof of the realization of certain 3-groups S with maximal class by 3-tower groups of dihedral fields E with degree 6, which could not be realized up to now.展开更多

The identification results of ELISA test, PCR and immunofluoresecence assay (IFA) specific for ALV-J were all positive. Based on the public full-length proviral genome sequence of ALV-J prototype strain HPRS-103, three pairs of primers were synthesized. The full-length proviral genome sequence of ZH-08 isolate is 7597 bp, which has a little difference with that of published full-length genome sequences, but its organization corresponds with typical retroviral genome structure; and known oncogenes were not included in its genome. According to the gp85 sequence comparison of ZH-08 isolate with those of the other reference strains in China and abroad, the highest similarity (93.7%) was with the YZ9901 isolate. Phylogenetic analysis, based on the gp85 gene, showed that the ZH-08 isolated here had the closest linkage to the SD07LK1 isolate. This study provides the basis for the biological characterization and pathogenesis research of the ZH-08 isolate.展开更多

The role of premorbid and current psychiatric disorders in impairment was ex-plored with a sample of 113 participants with CFS. Subgroups were created based on past and current psychiatric status including those whose psychiatric history was premorbid and current, postmorbid and current, past but not current, and those with no lifetime diagnosis. Results from a one-way MANOVA revealed that patients with a premorbid and current psychiat-ric disorder reported significantly higher pain severity, more somatic symptoms, poorer sleep quality, and poorer quality of life than those with no psychiatric history. Levels of fatigue and physical functioning among patients with CFS were unrelated to the four subgroups in this study. Although those with a premorbid and current psychiatric disorder were differentiated from those with no psychiatric history on some markers of impairment, the sample as a whole had severe fatigue-related impairment, which is the cardinal symptom of CFS. Implications for research are discussed.展开更多

文摘In this paper,we show how to use the dual techniques in the subgroups to give a secure identity-based broadcast encryption(IBBE) scheme with constant-size ciphertexts. Our scheme achieves the full security(adaptive security) under three static(i.e. non q-based) assumptions. It is worth noting that only recently Waters gives a short ciphertext broadcast encryption system that is even adaptively secure under the simple assumptions. One feature of our methodology is that it is relatively simple to leverage our techniques to get adaptive security.
