Objective] To analyze the effect of powder for ascending and descending on patients with different cough. [Method] The treatment group patients had still cough with conventional western medicine for two weeks, and initial treatment group patients had not any treatment after cough. All these patients were treated with powder for ascending and descending according to different Chinese traditional medicine syndromes cough. [Results] There were 49 patients, and 17 cases were the initial diagnosed group and 32 patients were the after treatment group. Patients with the improvement of the symptoms of cough and throat were effective in 15 cases(88.2%), while in patients with the improvement for sputum symptoms in initial group were 16 cases(94.1%), and 27 case(84.4%) in treatment group. It had no statistically significant difference between the two groups(χ2=0.006, P=0.940). Cough concrete improvement between the two groups showed no significant difference(χ2 =0.006, P =0.465). Between the two groups cough, throat and sputum symptoms overall improvement rate was 87.8%(43/49), no significant difference between the two groups(P>0.05). [Conclusion] Regardless of the treatment patients or untreated patients, treatment with powder for ascending and descending had good effect in improvement of the symptoms of cough, and the improvement of throat and sputum was effective, too.

Objective To investigate risk factors of Alzheimer's patients with aspiration pneumonia and inter-vention,to provide a reference for clinical treatment.Methods From January 2013 to June 2014,322 patients with Alzheimer's disease were selected,the incidence of aspiration pneumonia was analyzed,and the age,gender,depression Tian water test grading,underlying diseases,aspiration and other potential factors were analyzed to get risk factors of aspiration pneumonia,and summarized countermeasures.Results Multivariate analysis showed that underlying disea-ses (95%CI =1.694 -5.319,P =0.011),invasive procedures(95%CI =1.884 -6.362,P =0.001),depression Tian water test grade(95%CI =2.184 -9.636,P =0.000),malnutrition(95%CI =2.501 -11.114,P =0.000), Glasgow Coma Scale(95%CI =1.271 -3.569,P =0.011),were risk factors for Alzheimer patients with aspiration pneumonia(P <0.05).Conclusion Alzheimer's patients with inhalation pneumonia have multiple risk factors,more expectoration should be done for caring,e.g.oral care,in order to reduce the probability of pneumonia.

Objective To investigate whether HA affects the inflammatory cytokines and chemokines of synoviocytes. Methods FLS were derived from the SD mice with knee OA by papaya enzyme and stimulated by IL-1. Then, FLS were cultured with 600 ~ 800 kDa HA. Anti-CD44 blocking experiments were determined. The expressionsof TNF-γ, IL-1 , IL-6 , MMP-3 , MMP-9 , CX3CL1 , CCL11 , CCL2 , CXCL12 were detected by RT-PCR. In addition, the tunel test was used to detect the apoptosis rate. Results MMP-3, CX3CL1 and CCL2 gene expression were down regulated by HMW-HA in unstimulated FLS and TNF-α,MMP-3, CX3CL1 and CCL2 expression were decreased by HMW-HA in IL-1-stimulated FLS. CD44 blocking inhibited the down-regulatory effects of HMW-HA. Besides, HMW-HA promoted cell apoptosis under condition of inflammation. Conclusion HMW-HA has an anti-inflammatory effect by down-regulating of pro-inflammatory cytokines and chemokines and promoting apoptosis, possibly through the interaction of CD44 and HMW-HA.

Objective To construct a shuttle plasmid for inducible gene expression in Borrelia burgdorferi (B.burgdorferi) with an advantage of flexible genetic manipulation.Methods The IPTG-inducible lac repressor/operator system from Escherichia coli (E.coli) was adopted and modified in the current study.The plasmid shuttle vector was developed by inserting multiple cloning sites,FLAG and HA tags into the shuttle vector by molecular cloning approaches.The target gene was inserted at the site under the control of the promoter (Tn5 derivate) in plasmid pQE30.This promoter contained two lac operators and a codonoptimized lacI gene driven by flaB promoter.Results A plasmid shuttle vector,pJJ275,was successfully constructed with the ability to express target genes in B.burgdorferi in the presence of IPTG.By using this system,a HA-tagged rpoS gene was introduced into the typical infectious strain B.burgdorferi B31.The target gene expression induced by IPTG was confirmed at transcriptional and translational levels.The RpoS dependent virulence factor of Borrelia,OspC,was also detected,indicating that the expressed protein was functional.Conclusion The constructed plasmid shuttle vector can express exogenous genes in B.burgdorferi with an inducible feature and an advantage of flexible genetic manipulation.It can be applied for genetic manipulation of B.burgdorferi involved in gene regulation and complementation.

In order to find the most suitable algorithm of T-wave end point detection for clinical detection, we tested three methods, which are not just dependent on the threshold value of T-wave end point detection, i. e. wavelet method, cumulative point area method and trapezium area method, in PhysioNet QT database (20 records with 3 569 beats each). We analyzed and compared their detection performance. First, we used the wavelet method to locate the QRS complex and T-wave. Then we divided the T-wave into four morphologies, and we used the three algorithms mentioned above to detect T-wave end point. Finally, we proposed an adaptive selection T-wave end point detection algorithm based on T-wave morphology and tested it with experiments. The results showed that this adaptive selection method had better detection performance than that of the single T-wave end point detection algorithm. The sensitivity, positive predictive value and the average time errors were 98.93%, 99.11% and (--2.33 ± 19.70) ms, respectively. Consequently, it can be concluded that the adaptive selection algorithm based on T-wave morphology improves the efficiency of T-wave end point detection.

BACKGROUND:For patients with rheumatoid arthritis and Kümmel ’s disease, how to effectively control back pain, to recover patient’s locomotor activity and to avoid a vicious cycle of disuse osteoporosis is a key therapeutic target. Kyphoplasty is a recently developed new technology of minimal y invasive spine surgery. Few reports concerned the kyphoplasty for rheumatoid arthritis and Kümmel ’s disease. OBJECTIVE:To assess the clinical outcome of bone cement kyphoplasty for the treatment of Kümmel ’s disease combined with rheumatoid arthritis. METHODS:From June 2012 to July 2013, 11 female patients at the age of 65.4±5.1 years with Kümmel ’s disease combined with rheumatoid arthritis, who suffered from severe back pain, were treated with bone cement vertebroplasty. Back pain and imaging indexes were compared and observed before surgery and during fol ow-up. Imaging indexes contained preoperative and postoperative anterior height of vertebral body after fractures, the ratio of anterior height to posterior height of the vertebral body, and local kyphosis angle (Cobb method). RESULTS AND CONCLUSION:No patients were lost to fol ow up. 11 patients were fol owed up for 6 to 12 months. Significant differences in fol ow-up and preoperative Visual Analogue Scale scores, anterior height of vertebral body after fractures, the ratio of anterior height to posterior height of the vertebral body, and local kyphosis angle were detected (P<0.05). Two patients experienced bone cement leakage. No severe complications appeared such as pulmonary embolism or neurological dysfunction. These data confirmed that bone cement vertebroplasty for rheumatoid arthritis combined with Kümmel ’s disease can effectively lessen back pain, partial y restore the height of vertebral body after fracture, rebuild spinal stabilization, reduce local kyphosis, and is a safe effective repair method.

Objective To study computer toxicity prediction technology and predict the acute toxicity of Chinese materia medica; To provide a new way and method for safety evaluation of traditional Chinese medicine. Methods First, Mold2 software (version 2.0.0) was used to calculate molecular descriptors of 7409 chemical components. After preliminary screening of molecular descriptors, quantitative structure-activity relationship (QSAR) models were built up with Random Forest (RF) for screening the optimum prediction model. From the 83 kinds of toxic Chinese materia medica in Chinese Pharmacopoeia (2010 edition), acute toxicity of 60 kinds of Chinese materia medica reported from monomer structure (1692 chemical components) were under prediction.Results Totally 7409 pieces of data were obtained. When the descriptors were 52, RF modeling accuracy and Kappa were the highest, 0.712 and 0.436 respectively. Compound clusters were divided into 3 types according to optimum molecule descriptors (52). The accuracy and Kappa of the optimum model for the first type of compounds were 0.666 and 0.476 respectively; the accuracy and Kappa of the optimum model for the second type of compounds were 0.804 and 0.381 respectively; the accuracy and Kappa of the optimum model for the third type of compounds were 0.709 and 0.373 respectively. It was predicted that 60 kinds of Chinese materia medica containing 0 violent toxic compound, 2 high toxic compounds, 172 medium toxic compounds and 1518 low toxic compound.Conclusion QSAR model for prediction study on acute toxicity of chemical components of Chinese mareria medica can provide references combination medication and experimental studies.
