Objective To analyses the effect of Buzhong Yiqi Decoction on the expression of Caspase-3 in human lung adenocarcinoma cells (A 549) tumor-bearing mice’spleen. Method 24 BALB/c mice were randomly divided into the control group(given saline),low-dose and high-dose Buzhong Yiqi Decoction groups,cisplatin(DDP)group;Buzhong Yiqi Decoction was administered twice daily for 10 days consecutively and DDP was administered once daily for 3 days consecutively, after 15 days was the spleens of all tumor-bearing mice were obtained.The expression of Caspase-3 protein and Caspase-3 mRNA in every group were detected by immunohistochemical method seperately and polymerase chain reaction method seperately. Results Compared with control group,the result of immunohistochemistry showed that the expression of the Caspase-3 protein in Buzhong Yiqi Decoction low-dose group and high-dose group were both ssignificantly increased (P<0.05). The differences hetween DDP group and control group was not significant, but the differences between DDP sroup and Buzhong Yigi Decoction Low-dose sroup and hishdoe group were significant (P<0.05, P<0.01).The result of RFPCR was accordance with the result of immunohisto chemistry. Conclusion Buzhong Yiqi Decoction can increase the expression of Caspase-3 protein in A549 ctumor-bearing mice’spleen,and promote the Caspase-3’s inducing effect on tumor cell apoptosis.

BACKGROUND:Knee osteoarthritis and rheumatoid arthritis are common arthritis in the knee.In late stage of arthritis,severe deformation and activity obstacle are found,which require total knee replacement.The total knee replacement not only can significantly relieve symptom,but also correct deformation and improve joint function.OBJECTIVE:To summarize classification of knee joint,techniques of knee replacement surgery and complications following replacement.METHODS:We retrieved Vip Database (http://www.cqvip.com) for titles and abstracts with the key words of "knee replacement,prosthesis,complication".Articles concerning clinical application of knee prosthesis were included.Articles in the same field that published recently or in authorized journals were included.A total of 20 literatures were included for review according to inclusion criteria.RESULTS AND CONCLUSION:Various artificial total knee prostheses were used in different patients in accordance with patients' condition,joint limitation degree,fixation method and meniscus function.Indication of different knee prostheses depends on bone and soft tissue of the knee,and quality and status of knee ligament,joint deformation and destruction degree of articular cartilage are responsible for the choice of prosthesis.Thrombosis of deep veins of the lower limb,pulmonary embolism,infection surrounding the prosthesis and prosthesis loose are common complications in joint replacement.

Gold nanostructures with unique optical and photo-thermal properties based on their size and shape have wide applica-tion potential in tumor diagnosis, imaging, photo-thermal therapy, and drug delivery because of surface plasmon resonance. The optical properties of gold nanomaterials allow its use for dark field imaging, optical coherence tomography, and two-photon imaging. Gold nanomaterials can also be used as carriers for a variety of fluorescent molecules and drugs, achieving multifunctional imaging, chemo-therapy, photodynamic therapy, and so on. Photon-electron and electron-electron interactions of gold nanomaterials, which are excited by near-infrared laser, will generate heat that can be used for tumor photothermal therapy. This phenomenon promotes drug release, and photoacoustic imaging. The combined application of hyperthermia and chemotherapy based on gold nanoparticles is effective in opti-mizing the efficacy of cancer treatments. Therefore, gold nanoparticles can integrate multiple functions into one single system and real-ize the integration of tumor diagnosis and therapy, which provide new insights for the on-demand therapy and personalized medicine de-velopment. This study reviews the recent progress of several gold nanoparticles in the integrated applications for tumor theranostics, in-cluding gold nanoshells, gold nanorods, hollow gold nanospheres, gold nanocages, and gold nanostars. The major strategies of gold nanomaterials in biomedical applications are also discussed.

Objective To explore the distribution and drug resistance of pathogen in hospitalized tumor patients and to provide reference for the clinical reasonable use of antibiotics and strengthening the hospital infection control. Methods 6 500 clinical speciments were tested in hospitalized tumor patients from January to December,2013.The drug susceptibilities were tested by automated microbiology system or Kirby-Bauer disk dilution method.Drug susceptibility tests were evaluated according to CLSI standard 2012.WHONET5.6 software data were used to analyze the data.The clinical distribution and the resistance results of bacterial were analyzed retrospectively. Results A total of 2 093 strains of pathogens were isolated from 6 500 clinical speciments,among these strains, the gram-negative bacteria accounted for 55.23%,the gram-positive bacteria accounted for 11.08%,and the fungi accounted for 33.68%.Klebsiella pneumoniae,Escherichia coli,Pseudomonas aeruginosa ranked the top three species of pathogens, accounting for 16.63%, 9.60%, and 7.98%, respectively. Staphylococcus aureus, Candidaalbicans ranked the first place of gram-positive bacteria and fungi,respectively.The antibiotic resistance of Escherichia coli was strong in Enterobacteriaceae, and its resistance rates to penicillins,cephalosporins, and quinolones were more than 60%.Of the Staphylococcus,the methicillin-resistant Staphylococcus aureus(MRSA) accounted for 10.00% and the coagulase-negative Staphylococcus (MRCNS)accounted for 87.10%.There was no vancomycin resistant Staphylococcus aureus and coagulase-negative Staphylococcus detected. Enterobacteriaceae strains were found most sensitive to imipenem;gram-positive bacteria were found most sensitive to vancomycin. Conclusion The hospitalized tumor patients are susceptible to pathogens, and the gram-negative bacteria are the predominant isolated pathogen.Etiology inspection and monitoring of antibiotics sensitivity provide experimental basis for clinical infection control and prevention.
