Objective To explore the optimal treatment options of Stanford type B aortic dissection. Methods A to?tal of 51 patients with Stanford type B aortic dissection who visited the General Hospital of Tianjin Medical University from May 2008 to March 2013 were analyzed retrospectively. Survival and recovery of patients were evaluated by follow ups. Pa?tients were divided to TEVAR group(40 cases)and conservative group(11 cases)according to the treatment they recieved. Results Operations were successful in all 40 patients. There were two cases of perioperative death(5%). And none of pa?tients died in TEVAR group during follow-up. One case among 11 patients who received conservative treatment dead in hos?pital(9.1%)while other 7 cases died during follow-up(63.6%). Kaplan-Meier survival curve showed that two-year survival rate of TEVAR group was significantly higher than that of conservative group. In TEVAR group, the maximum diameter of the aorta presented a decreasing trend and thrombosis was seen in artificial lumen with time going after operation. Conclu?sion For patients with Stanford type B aortic dissection, TEVAR presented a high success rate and promoted remodeling of the aortic genuine and aritificial lumen. What’s more, it can significantly improve patient’s survival rate and recovery in short or mid-term period compared with effect of traditional conservative treatment.

BACKGROUND:Health has been paid more and more attention in modern society, the health of those special groups, such as the elderly and the disabled, should also be brought to the forefront. As fitness equipment is more and more popular in contemporary, our focus should be transferred to the use of fitness equipment for these special groups.
OBJECTIVE:To put forward the design strategy of fitness equipment control interface, for the special groups to use common fitness equipment comfortably and conveniently.
METHODS:Based on the research of existing fitness equipment control interface, according to the usage habits and cognitive awareness of special groups on control interface, a new design strategy has been put forward using the general design method and ergonomics.
RESULTS AND CONCLUSION:Based on the existing 45 kinds of exercise bikes, 84 kinds of running machines and 129 kinds of treadmil fitness equipments, we found that these equipments are designed for common users in the aspects of design and production process and control interface. Universal design is a design concept beyond the lack of capacity to meet the different needs of different populations, and designed products can reduce or even eliminate the difference in the ability of special populations and the general population in use. The new strategy makes design of fitness equipment control interface generalized and good man-machine interactive, which can meet the demand of the special groups and help them do fitness exercise to improve their health and body function.

Background and purpose:As a new candidate tumor suppressor gene, p33ING1b has many biological functions. This study was done to investigate its role in the regulation of the proliferation of human colon cancer cell line SW480. Methods:The pcDNA3.1(+)/p33ING1b/SW480 cells were identified by Western blot and S-P immunohistochemical method. In order to elucidate the effect of expression of exogenous p33ING1b gene on the colorectal cancer cell SW480, the proliferation rates were analyzed by growth curves and colony formation assay in soft agar for cells including SW480, pcDNA3.1(+)/p33ING1b/SW480 and pcDNA3.1(+)/SW480. At same time, the apoptotic rate of cells and the cell cycle analysis were also tested by flow cytometry.Furthermore,using western blot analysis,we detected the expression level of the protein p53, p21WAF1,Bax and Bcl-2 in those three group cells, which initially indicate the molecule mechanism of inducing apoptosis by gene p33ING1b. Results:The cell growth rates of SW480 cells transfected with pcDNA3.1 (+)/p33ING1b were slower than those transfected with pcDNA3.1(+) or untransfected.The colony formation efficiency of pcDNA3.1(+)/p33ING1b/SW480 were decreased and the apoptotic rates were increased compared with pcDNA3.1(+)/SW480 and SW480(P0.05). Conclusion:After overexpression of exogenous p33ING1b protein in SW480 cell, there were inhibition of the proliferation rate and induction of apoptosis, the molecular mechanism might be associated with up- regulated expression of Bax and down-regulated expression of Bcl-2 by p33ING1b gene.

Salvia miltiorrhiza is a traditional Chinese medicine (TCM) and is widely used as a clinically medication for its efficiency in treating cardiovascular disease. Due to TCM is a comprehensive system, the mechanism of S. miltiorrhiza treating cardiovascular disease through integrated multiple pathways are still unclear in some aspects. With the rapid progress of bioinformatics and systems biology, network pharmacology is considered as a promising approach toward reveal the underlying complex relationship between an herb and the disease. In order to discover the mechanism of S. miltiorrhiza treating cardiovascular disease systematically, we use the auxiliary mechanism elucidation system for Chinese medicine, built up a molecule interaction network on the active component targets of S. miltiorrhiza and the therapeutic targets of cardiovascular disease to offer an opportunity for deep understanding the mechanism of S. miltiorrhiza treating cardiovascular disease from the perspective of network pharmacology. The results showed that S. miltiorrhiza treating cardiovascular disease through ten pathways as follows: improve lipid metabolism, anti-inflammation, regulate blood pressure, negatively regulates blood coagulation factor and antithrombotic, regulate cell proliferation, anti-stress injury, promoting angiogenesis, inhibited apoptosis, adjust vascular systolic and diastolic, promoting wound repair. The results of this paper provide theoretical guidance for the development of new drugs to treat cardiovascular disease and the discovery of new drugs through component compatibility.

OBJECTIVETo assess the clinical efficacy of acupuncture at key acupoints combined with the routine rehabilitation training of limb function on spasmodic hemiplegia after cerebral infarction.

METHODSEighty-six cases were randomized into an acupuncture combined with rehabilitation group (group A, 44 cases) and a rehabilitation group (group B, 42 cases). In group A, the key acupoints were selected from head, face, chest, abdomen, shoulder, back, hands, feet and ankles such as Cuanzhu (BL 2), Danzhong (CV 17), Jianyu (LI 15) and Yanglao (SI 16) were stimulated with acupuncture. In combination, the routine limb rehabilitation training was applied, once every day. In group B, the routine limb rehabilitation training was applied alone. In both groups, 10 treatments made one session and 2 sessions were required totally. Before and after treatment, Fugl-Meyer scale and functional independent measurement (FIM) scale were adopted to assess the limb motor level and the activity of daily life in the patients respectively. The modified Ashworth scale was used to assess the effect of anti-spasm.

RESULTSThe total effective rate of anti-spasm was 90.9% (40/44) in the group A, which was superior to 73.8% (32/42) in the group B (P < 0.05). After 2 sessions of treatment, Fugl-Meyer score and FIM score were all improved in both groups (all P < 0.05) and the results in the group A were better than those in the group B (all P < 0.05). Additionally, the improvement of FIM score after the 1st session of treatment in the group A was better as compared with the group B, indicating the significant difference (P < 0.05).

CONCLUSIONAcupuncture at key acupoints combined with rehabilitation therapy effectively relieves the spasmodic condition of the patients with post-stroke spasmodic hemiplegia, improves the limb function and the life activity of the patients.

The laser-induced breakdown spectroscopy (LIBS) was applied to perform a qualitative elementary analysis on four precious Tibetan medicines, i. e. Renqing Mangjue, Renqing Changjue, 25-herb coral pills and 25-herb pearl pills. The specific spectra of the four Tibetan medicines were established. In the experiment, Nd: YAG and 1 064 nm-baseband pulse laser were adopted to collect the spectra. A laser beam focused on the surface of the samples to generate plasma. Its spectral signal was detected by using spectrograph. Based on the National Institute of Standard and Technology (NIST) database, LIBS spectral lines were indentified. The four Tibetan medicines mainly included Ca, Na, K, Mg and other elements and C-N molecular band. Specifically, Fe was detected in Renqing Changjue and 25-herb pearl pills; heavy mental elements Hg and Cu were shown in Renqing Mangjue and Renqing Changjue; Ag was found in Renqing Changjue. The results demonstrated that LIBS is a reliable and rapid multi-element analysis on the four Tibetan medicines. With Real-time, rapid and nondestructive advantages, LIBS has a wide application prospect in the element analysis on ethnic medicines.
