Acquaintance of the lymph node is very important to evaluate whether the tumor is malignant or benign and therefore to the treatment of the tumors. Lymphography is now considered the gold standard for this purpose. Many computer aided diagnose (CAD) technologies have been developed to help radiologists to diagnose the tumor by the lymphography cases. In this paper, a computer aided diagnose model is constructed by Semi-naive Bayes Classification. The experiments carried out in our laboratory validated the Semi-Naive Bayes Classification on lymphography case. The result of experiments showed that Semi-Naive Bayes Classification could classify lymphography case effectively.

Objective:Study on the clinical application and analysis of structured electronic medical records in our hospital in last.Methods: Discharged patients data selected from July 2012 to June 2014, using statistical methods for data processing, 8000 case files were divided into two groups: Group A and Group B.Results: After comparing the two groups of two groups of data, and ultimately disease coding accuracy rate 94.88%, fill in the correct rate increased 88.38%, missing rate decreased 4.63%, two groups had no significant difference data; The quality of writing the doctor increased gradually, the error rate tends to be stable, structured clinical application to control.Conclusion: Sequential specification writing medical doctor, scientific analysis of medical record information, the clinical application of structured electronic medical records the error rate is reduced in the operation, improve the accuracy, more standardized, accurate, standardized.

AlM: To observe the effect of dacryocystorhinostomy for the treatment of chronic dacryocystitis using nasal endoscope and discuss the operation technique. METHODS: A retrospective clinical analysis was performed on the clinical data followed up for 6 ~12mo from 140 patients (169 eyes) with dacryocystorhinostomy for the treatment of chronic dacryocystitis using nasal endoscope. The effect of the treatment was evaluated and the operation technique for the treatment of chronic dacryocystitis using nasal endoscope was discussed.RESULTS: ln all of cases 155 eyes ( 91. 7%) were recovery, 3 eyes ( 1. 8%) were improved, and 11 eyes (6. 5%) were failure. The total efficiency was 93. 5%, there was no significant difference compared with traditional dacryocystorhinostomy group (χ2=3. 743, P>0. 05). CONCLUSlON: Dacryocystorhinostomy using nasal endoscope for treatment of chronic dacryocystitis has a good curative effect. Techniques including lacrimal sac location and size, colostomy position and size, treatment of colostomy mucosal flap and nasal disease, postoperative follow - up and physical condition of patients are likely to affect the operation curative effect.

Objective:To explore the correlation between the characteristics of contrast-enhanced sonography of intraoperative glioblastoma multiform (GBM) and molecular markers of isocitrate dehydrogenase-1(IDH1).Methods:A retrospective analysis were performed in 30 patients who underwent neurosurgery and pathologically confirmed to be GBM at Beijing Tiantan Hospital from May 2018 to April 2019. All neurosurgical glioblastoma patients after craniotomy underwent conventional ultrasound and contrast-enhanced ultrasound(CEUS) guided navigation. The characteristics of the ultrasound imaging (whether the tumor involves the structure of the corpus callosum, the clarity of the tumor boundary after enhanced ultrasound and whether the tumor has necrotic areas with enhanced ultrasound images) were analyzed. The ratio between tumor necrosis area and whole tumor area (N/W) was measured, and the correlation with IDH1 gene expression was analyzed.Results:There were statistical differences in clarity of tumor boundary after CEUS and tumor necrosis after CEUS between positive IDH1 and negative IDH1 groups(all P<0.05). The positive expression of IDH1 was negatively correlated with the N/W area of the contrast-enhanced ultrasound mode( r=-0.756, P<0.05), suggesting that the expression level of IDH1 gene was negatively correlated with the area of tumor necrosis. Conclusions:Ultrasound contrast agent examination can more accurately distinguish the active proliferation area, hemorrhagic necrosis area and peripheral edema area of glioblastoma. Accurately identifying the extent of tumor necrosis area through ultrasound contrast agent examination can predict expression of IDH1.

Objective:To discuss the role of clinical pharmacists in perioperative drug treatment for a patient after renal transplan-tation. Methods:Clinical pharmacists participated in the drug therapy for a patient after renal transplantation. Pharmaceutical care and health education were performed for the patient in the aspects of immunosuppression, anti-hepatitis B virus, gastric mucosa protection, diarrhea, acute rejection and the other treatment programs. Results:The participation of clinical pharmacists in the clinical treatment for the patient improved therapeutic scheme and promoted therapeutic efficacy. Conclusion:The participation of clinical pharmacists in clinical drug therapy for patients can provide individualized service to improve reasonable, effective and economical drug use.

The following aspects were described in detail: the advantages of Pichia pastoris in the expression of heterologous genes, the mechanism of the heterologous gene integrations, the glycosylation of the expressed protein and the modification of the post-translated protein.

OBJECTIVETo analyze the imaging features of osteopoikilosis and its diagnosis knowledge.

METHODSThe imaging data of 9 patients with osteopoikilosis were analyzed retrospectively, including 6 familial cases and 3 sporadic cases. In 6 familial cases,there were 4 males and 2 females with an average age of 28 years old ranging from 10 to 63 years. Clinical manifestations of 1 familial case were left knee pain and limitation of activity for 3 years, and other 5 cases without clinical manifestation. In 3 sporadic cases, there were 2 males and 1 female with an average age of 33.7 years old ranging from 25 to 44 years. Three sporadic cases had obvious injury history with following up from 6 to 12 months. All imaging results of 9 cases were observed.

RESULTSThe imaging data of 6 familial osteopoikilosis showed the multiple round or oval nodes within bone with clear margins, uniform density, different size. The occurrence of the hyperostotic spots preferentially localized in the epiphyses and metaphyses of the long bones, and carpus and tarus. X-ray features of 3 sporadic osteopoikilosis were similar to that of 6 familial cases and for 6 to 12 months follow-up X-ray features were unchanged.

CONCLUSIONThe imaging features of osteopoikilosis are relatively specific such as the multiple mottling dense focal within bone with clear border and bilateral symmetry, and the focus located on cancellous bone and the diaphyses usually is unaffected. The imaging is a valuable examination for the accurate diagnosis of osteopoikilosis.
