BACKGROUND:Rib fractures are frequently treated with analgesic or compression band,which relieves pain but attenuates respiration.Memory metal chest shield as a new product has been used clinically for patients with multiple rib fractures to alleviate the pain.It displays many advantages compared with traditional approaches OBJECTIVE:To compare the effect of the memory metal chest shield versus the traditional fixation for multiple rib fractures.METHODS:A total of 104 patients with multiple rib fractures confirmed by transthoracic X-ray were selected and randomly divided into control group(n=40)treated with the traditional fixation methods(chest strap or a thick pad)and experimental group(n=64)treated with memory metal chest shield.At 1,24,48,and 72 hours after admission,the visual analog scale(VAS)at rest and cough.the incidence of pulmonary complications,and hospitalization were recorded Of them,32 from the experimental and21 from the control group rccepted pulmonary function tests.and their vital capacity was recorded at 1,24,48,and 72 hours after treatment RESULTS AND CONCLUSION:Pain intensity of experimental group was reduced at rest,while significantly reduced in forced breathing(such as cough).Of the 32 patients with use of memory metal sheeting,vital capacity continuously increased during the observation period,but pulmonary complications were significantly less,and the average hospital stay was significantly less than the control group(P＜0.05).Results show that the memory metal shield displayed fixation effect on the area of broken ribs,which significantly reduced pain,increased lung capacity,reduced the incidence of pulmonary complications and shortened the average length of stay.It is a simple and effective method of treating multiple rib fractures .

During cell apoptosis,a series of characteristic changes occur in the cell configuration and,according to recent findings,in the cytoskeleton as well,including degradation,condensing and maldistribution of the cytoskeleton reticular formation.Through investigations of the biological activity and function of the cytoskeleton protein,the dynamic changes of the cytoskeleton during cell apoptosis and related regulatory factors,we found that the change of configuration is based on that of the cytoskeleton during cell apoptosis,which suggests that we can achieve the purpose of curing tumors and other diseases by inducing cell apoptosis through changing the cytoskeleton configuration.

Autophagy can be activated after cerebral ischemia and involved in the occurrence and development of ischemic brain injury. Therefore, the study of autophagy related signal transduction pathways may provide a new therapeutic target for ischemic brain injury. This article reviews the signal transduction pathways of autophagy after cerebral ischemia.

OBJECTIVE: To construct the data envelopment analysis (DEA) inference model for word-computing. METHODS: Firstly, a syndrome assembly was established based on the Chinese medical patterns contained in Shanghanlun, then the subjective evaluation was set by the linguistic description for the corresponding patterns. Secondly, with the data of decoctions, the evaluation was modified according to the requirement of DEA to construct the inference model. Finally, the word-computing was completed by the inference function of this model. RESULTS: DEA model could describe the diagnostic thinking process of Shanghanlun theory. CONCLUSION: DEA model can upload the information embodied among the words of the corresponding classical doses and symptoms, and it provides a kind of method for modernization of traditional Chinese medicine.

Objective To screen the flocculatnt-producing strain from activated sludge that can treat azo dyeing wastewater effectively.Methods Screening and rescreening were used to acquire the strain which possesses high efficiency of flocculatant production and the strain was identified.The character of microbial flocculant(MBF) and the ability to treat azo dye wastewater were studied.Results A strain of high-efficiency bioflocculant-producting bacteria(AJ-6),initially identified as Alcaligenes sp,was screened.The bioflocculant produced by the strain was able to flocculate kaolin suspension with 94.4% and fly ash suspension with 98.9% respectively.The flocculation activity distribution tests showed that the active components of the bioflocculant existed in the supernatant fluid after centrifugation.It had good treatment efficiency in treating azo dyes methyl orange wastewater.The maximal efficiencies of removing CODCr and chroma from the wastewater were 81.3% and 94.2%.Compared with the other flocculants,the performance of MBF was better than that of polyacrylamide(PAM),aluminum sulfate,ferrous sulfate.The MBF was more thermostable when treated with 100 ℃ for 30 min,and the animal toxicity test showed that the MBF had no acute toxicity to mice.Conclusion The bioflocculant produced by the strain AJ-6 is applicable to treat azo dyeing wastewater and can be also used for the other wastewater.
