Objective To provide the reference for early diagnosis and treatment of breast cancer by detecting its metastasis-related genes.Methods Breast cancer metastasis-related genes were searched from PubMed-covered papers with their conception matched according to the MetaMap.A gene-gene matrix was generated using data a-nalysis software.An interaction network of breast cancer metastasis-related genes was established using Ucinet 6 and its related indexes were analyzed.Results tp53, thra, erbb2, esr1, cdh1, egfr, nr4al and cd69 were the core genes for breast cancer metastasis.Conclusion Co-word analysis can show breast cancer metastasis-related genes. However, the role of cd69 in breast cancer metastasis remains unclear and is thus necessary to be further confirmed.

The paper discusses the necessity and urgency of hospital ownership reform. and pinpoints the focal and difficult points of the task. It also identifies the goals of the reform, viz. establishment of a medical and health system that fits in with the development demands of a socialist market economy, which is of great significance. It can be seen both in theory and in practice that for a pretty long period of time in China, public hospitals, providing basic medical security for the broad masses of people will occupy a leading position whereas private hospitals known for their outstanding service and quality, will play a bigger role only when the living standards of the general population have reached a fairly high level.

Objective To observe the distribution of circum-patella nerve fibers in the soft tissue to provide experimental evidence,which is significant in denervation for Total Knee Arthroplasty (TKA).Methods Patella specimens were collected from 4 cadavers (2 cases of diabetic foot,lcase of lower extremity arterial occlusive,and 1case of car accident),all 4 of which were resected soft tissue with a dimension of 0.5cm × 0.5cm and full depth thickness around patella more than 0.5cm for histology and morphology observation.The nerve fibers histology and morphology were observed in all resected specimens with HE staining and silver-gilt glycine staining in the same field of microscopic vision.Results Anatomy found that the vascular network form skins directly involved in the patella nourish hole area and in the 10,2,4,7 clock point have found that blood vessels into the patella.There have a large number of nerve fibers near to the patella under the microscope,but there were no significant difference in the nerve fibers region distribution of all specimens.There were some into patella nerve fiber paths in side of patella soft tissue,which lied in 7,11 and 13 clock point,but outside no this phenomenon.The distribution of circum-patellar nerve fibers were described as distribution of regional concentration,which lied in much more 5,6,7 clock points and 10,11,12,1,2,clock points,in which the quadriceps tendon and patellar tendon have more than the others.In the 13 clock point,the fascia and periosteum of nourish hole area were also found in a large number of nerve fibers,and there were laminar distribution in different soft tissue layers,which were collected much more in synovial layer,fat pad,tendon near to patella.Conclusion There are much more nerve fibers near to the patella and some into patella nerve fiber paths in the medial side and nourish hole area.Nerve fibers distribution of circum-patella can be described as laminar distribution and regional concentration ,which is more in the centre,bottom more than top,outside more than inside,the bipolar more than the others.The patella denervation operation by reducing the number of peripheral nociceptors to achieve desensitization is feasible in TKA.

Objective To establish a quality standard of Shutongantai Capsules. Methods Thermo C18 column was used with methanol-0.1% phosphoric acid as mobile phase. The flow rate was 1.0 mL/min, detection wavelength was 254 nm, and column temperature was 30 ℃. Results Emodin showed a good linear relationship in the range of 0.016-0.080 μg (r=0.999 6). Chrysophanol showed a good linear relationship in the range of 0.032-0.160 μg (r=0.999 8). Conclusion The established method is simple, feasible and reproducible, and can be used for the quality control of Shutongantai Capsules.

Objective To explore the cognitive function,feature of P 300 event-related potentials and the relationship of them in children with epilepsy.Methods Auditory P 300 was measured by oddball paradigm and intelligence quotient was tested by WSIC-RC in 38 children with epilepsy.Results 1. The rates of FIQ less than normal IQ were 65.8 %, impaired intelligence 28.9 % in patient group. 2.The latencies and the amplitudes of P 300 were significantly delayed and decreased respectively in both patient groups (P

Objective:To study the antimicrobial susceptibility of periodontopathic bacteria associated with failing implants to commonly used antibiotics in periodontal therapy and dental practice.Methods:Antimicrobial susceptibility of bateria isolates was determined by the method of microbroth dilution and the activities of 8 kinds of antibiotics against international laboratory strains and clinical isolates of Provotella intermedia (Pro.I), Porphyromonas gingivalis (Pg), Actinobacillus actinomycetemcomitans (Aa), Fusobacterium nucleatum (Fn) were examined.Results:Ofloxacin, clindamycin, tinidazole and metronidazole showed stronger antibacterial activity aginst Pro.I,Pg,Aa and Fn with MIC_ 90 ≤0.5 ?g/ml and MBC_ 90 ≤0.5 ?g/ml.Conclusion:Commonly-used antibiotics are potential against bacteria isolated around failing implants.

Objective To investigate perioperative nursing of interventional therapy for patients with chronic occluded internal carotid artery. Methods We retrospectively analyzed the clinical nursing data of 12 patients with chronic occlusion of internal carotid artery who were successfully performed recanalization for the occluded vessels. Results The vital signs of all patients were normal during the procedures. The patients got favorable outcomes and no complications occurred during the perioperation. Conclusions Interventional therapy for chronic occlusion of internal carotid artery is a new technology for carotid diseases. Perfect preoperative health education and psychological nursing, comprehensive monitoring of vital signs and nerve function, strengthening body position nursing can ensure prevention of complications and the success of surgery.

BACKGROUND:Induced pluripotent stem cels and mesenchymal stem cels-derived microvesicles have been confirmed in various tissue repairs, which are expected to become more effective and safe therapy for articular cartilage repair. OBJECTIVE:To overal understand the research progress in the use of induced pluripotent stem cels and mesenchymal stem cels-derived microvesicles in articular cartilage repair. METHODS: A computer-based search of PubMed and CNKI was performed by the first author for articles related to stem cel treatment of osteoarthritis published from 2003 to 2015. The keywords were “articular cartilage injury, bone marrow mesenchymal stem cels” in English and Chinese, respectively. In the same field, articles published recently or in authorized journals were preferred. RESULTS AND CONCLUSION:Articular cartilage injury is stil a difficulty in the orthopedics. Many repair methods have been reported, but they al have limitations. Induced pluripotent stem cels and mesenchymal stem cels-derived microvesicles bring a new hope for patients with articular cartilage injury. However, there are stil many problems to be solved, such as extracting and purifying a large amount of cels, proliferation and differentiation potentials, and mechanism underlying cartilage repair.
