Objective To explore the clinical behavior,pathological and immunohistochemical characteristics and diagnosis, treatment methods of gastrointestinal stromal sarcomas (GISS). Methods Retrospective analysis was perfomed over 36 GISS patients based on clinical data and pathological data. Results GISS occurred more in the stomach and small intestine, than colon and rectum. Immunohistochemical staining showed CD117, CD34 expression,the positive rates were 91.7% and 86. 1%. Conclusion GISS is a rare malignant tumor, GISS diagnosis depends on the histologic and immunohistochemical test. CD34 and CD117 in the positive diagnosis has its special significance. Surgery is the main treatment.

The purpose of this paper is to present the research on the molecular biological characteristics of proto-oncogene pim-2 and to analyze the related mechanism. Proto-oncogene pim-2 was studied and analyzed by the bioinformatics method and technology. With an online server, the chromosomal localization of pim-2 gene was analyzed, and the exon, open reading frame, CpG island and miRNAs complementary fragments and the like were predicted. With bioinformatics software, the physicochemical property of transcription protein of proto-oncogene pim-2 and various modification sites of protein sequence, such as ubiquitination and glycosylation, were predicted, the antigenic index was calculated, and the spatial structural was modeled. The research findings showed that the proto-oncogene pim-2 comprised six exons, the CDS (coding sequence) transcribed a section of peptide chain including 311 amino acids, a gene promoter has a CpG island, and the 3'UTR region contains an miRNA gene. The molecular weight of the Pim-2 protein was 34,188. 47, the isoelectric point was 5.78, the instability index was 45.87, and the extinction coefficient was 279nm. A plurality of covalent modification sites, two ubiquitination sites, four glycosylation sites, an SUMO sumoylation site, a nitrosation site, two palmitoylation sites and sixteen regions with higher antigenic index were distributed in the protein sequence. This research showed that the related regions and modification sites distributed on the sequence of proto-oncogene pim-2 were closely related to the carcinogenic effect thereof.

OBJECTIVE:To investigate the role of clinical pharmacists in pediatric severe infection treatment,and to provide reference for rational drug use in clinic. METHODS:Based on related typical cases,the breakthrough points of clinical pharmacists providing pharmaceutical care in pediatric severe infection treatment plan were introduced. RESULTS:Clinical pharmacists formu-lated multi-drug resistance pathogenic antibacterial plan according to the results of pathogenic microbiological examination,use pharmacokinetics/pharmacodynamics,excluded interference to pediatric anti-infection treatment from ADR,and guideline and eco-nomical factors of patients. CONCLUSIONS:Clinical pharmacists adopt professional knowledge of pharmacy to provide pharmaceu-tical care in pediatric severe infection treatment and play professional assisted role so as to guarantee safe,effective and economical treatment.

Fracture healing activity of aqteous extracts of rhizome of Drynaria fortunei (Kunze ) J.Sm.,D.sinica Diels ( "Gusuibu"),and its main constitucnt naringin were examined and coufirmedwith an experimental bone-injury model rat femur inferior. Results showed that they werefefective for healing of experimental rat bone-injury.

Objective To explore clinical application of the combined therapy of manual small incision cataract surgery (MSICS) with intraocular lens (IOL) implantation and trabeculectomy for patients with refractory glaucoma and coexisting cataract.Methods In our hospital,68 patients (76 eyes) with angle-closure glaucoma of continuously high intraocular pressure (lOP) and coexisting cataract were included in this study from April 2008 to October 2011.All of them were treated with the combination of MSICS with IOL implantation and trabeculectomy.Postoperative visual acuity,IOP,anterior chamber depth (ACD),filtering bleb,ocular fundus and complications were observed.Results Each operation was successfully completed.Postoperative visual acuity and IOP were significantly improved and decreased,respectively,compared to the preoperative.ACD was deepen and filtering bleb was effectively established in the postoperative eyes without significant complications.Conclusion The combined surgery of MSICS with IOL implantation and trabeculectomy might effectively increase visual acuity and decrease IOP,which was a safe and effective approach for patients with refractory glaucoma and coexisting cataract.

Objective To study the drug retention of HPC MMC in bladder after intravesical instillation. Methods The pharmacokinetics of the intravesical mucous adhesive anticancer agent HPC MMC in urine and in tissue were comparatively studied with conventional mitomycin C aqueous solution(S MMC) by means of animal experiment. Results After instillation, the half life of MMC in urine in the 2 groups was 2.61 h and 0.56 h and in tissue 2.33h and 0.46 h respectively. Conclusions Suggesting that HPC MMC remained longer within the urinary bladder. It may be therapeutically more efficient.

Objective To study the ultrasound-guided treatment by real-time biplane imaging in animals and patients. Methods In 6 dogs gallbladders were substituted as hepatic cysts. The shapes of gallbladders and spatial positions of needle tips in gallbladders were studied by real-time biplane imaging before and during treatments. During treatments of 3 renal cysts the changes of cysts and the spatial relations between needle tips and renal cysts were observed to confirm that the needle tips were always in the cysts. In 2 cases of hepatocellular carcinoma boiloff of the tissue around the antenna was observed by real-time biplane imaging during microwave coagulation. Results It was rapid and convenient to acquire the shape information of objects and locate the position of puncture by real-time biplane imaging. And it was more convenient to observe the spatial relation between needle tips and objects of treatment than by conventional single-plane imaging. Conclusions The method of real-time biplane imaging has great advantages in ultrasound-guided treatment.

Objective To explore the clinical value of real-time three-dimensional echocardiography (RT-3DE) in percutaneous transcatheter closure treatment of atrial septal defect (ASD). Methods The sizes,shapes and sites of ASD were visualized by RT-3DE and measured by full volume rendered three-dimensional echocardiography (3DE) before operation and after closure operation in 11 ASD patients,and compared with those from two-dimensional echocardiography(2DE) and the operation. Results Before the operation,RT-3DE visualization showed that the secundum ASD′s sites of the 11 patients were central and shapes were mostly ellipse. In this study a significant difference was found in the measurements of long distances of ASD between 3DE and 2DE [( 28.9 ? 8.2 )mm vs ( 20.0 ? 7.3 )mm,P 0.05 ]. Maximal diameters of defects measured by 2DE[( 21.1 ? 3.5 )mm,P

Objective To evaluate the value of intraoperative ultrasonography (IUS) in detecting the lymph nodes in mediastinum and hilum during lung cancer surgery. Methods Lymph nodes were detected in every part of the mediastinum and hilum by IUS in 33 cases with lung cancer during surgery. The number, size and location of lymph nodes were recorded, and the metastasis to lymph nodes was predicted by the sonographic features and geometric measurement respectively. Mediastinum was explored and lymph nodes resection was performed in each case, and each resected lymph node was sent for pathological examination. Results The sensitivity of IUS in detecting lymph nodes in mediastinum and hilum was 83.6% (163/195) and the positive predictive value was 97.0%(165/168). The result of detecting lymph nodes with IUS was influenced by their location and size. The sensitivity, specificity and accuracy of IUS in diagnosing lymphatic metastasis with respect to geometric measurement were 70.3%, 71.7%, 71.2%, respectively, and were 85.7%, 75.0%, 83.3%, respectively, with respect to sonographic features. Conclusions IUS was an effective method for lung cancer surgery in detecting mediastinum lymph nodes.
