Objective To study the nursing methods of gastrointestinal cancer patients undergoing continuous hyperthermic peritoneal peffusion chemotherapy (CHPPC) in the peri-operative period.Methods A total of 126 patients with gastrointestinal cancer underwent continuous hyperthermic peritoneal perfusion chemotherapy,and nursing care was implemented continuously,comprehensively and individually.Results All of the patients underwent continuous hyperthermic peritoneal perfusion chemotherapy successfully,without any complication occurred.Conclusions Intensive and effective nursing care is helpful to carry out continuous hyperthermic peritoneal perfusion chemotherapy safely,and avoid the complications.

As the implementation of national policy which calls for college graduates to work in grassroots posts,it is one of the key and urgent issues in current college employment task to guide and encourage college graduates to work in grassroots posts.By investigating the bachelor graduates' attitude towards working in grassroots posts in Shenyang medical college and analyzing the investigation data,this paper points out influential factors of medical graduates' selection of employment,and comes up with positive and effective countermeasures to promote the grassroots employment of medical graduates.

To explore the relationship between serum total bile acid concentration and fetal prognosis in patients with intrahepatic cholestasis of pregnancy (ICP).A total of 131 ICP patients were divided into mild and severe ICP groups according to serum total bile acid concentration.And another 100 normal subjects during the same period were selected as control group.Their medical records and fetal prognoses were analyzed.The serum total bile acid,liver enzyme and lipid concentration of ICP patients were all significantly higher than those of the controls (P ＜ 0.01).The fetal prognoses of ICP patients were significantly different with those of controls (P ＜ 0.05).A high serum level of total bile acid of ICP patients may produce serious adverse effects on fetal prognosis.

[Objective]To explore the curative effect of the three diamen sional external fixation frame and limited internal fixation in treating the comminuted fracture of the shaft of humerus.[Method]Twenty-eight patients of the comminuted fracture of the shaft of humerus were treated from Jan 2000 to May 2006.According to the AO/ASIF,there were 5 cases of the B1 type,3 cases of the B2 type,9 cases of the B3 type,6 cases of the C1 type,4 cases of the C2 type,1 case of the C3 type.All of them were treated by the three diamensional external fixation frame and limited internal fixation of the screws or wires,and all of them were given the reasonable rehabilitation training at 3 day after the operation.The curative effect of the operation,the complications,the fracture healing and the function appraisal were analyzed.[Result]The 28 patients were followed-up for 10～15 months(average 13 months),27 cases had the frature healed and the healing rate was 96.4%.The healing period of the fracture lasted from 12 weeks to 33 weeks,average 19.5 weeks.Only 1 case was not healed.The functions of the shoulder and the elbow were normal,the excellent rate was 92.8%.[Conclusion]The three diamensional external fixation frame and limited internal fixation is a better method in treating the comminuted fracture of the shaft of humerus.It fits the rule of minimal-invasive-biology. The operation is simple,and the fixation is reliable,the function is satisfactory.

Objective To evaluate the effects of health management of stomatology on the marginal bone resorption of minimally invasive implant in the elderly.Method Tottally 54 implants were placed in 37 elderly patients of missing teeth in maxillary molar areas and the patients were randomly divided into health management group and control group.Patients in the group of health management were guided to master the proper techniques of oral hygiene practices before and after the implantation and periodontal maintenance were carried out carefully until 1 year after loading of restoration.In the control group, oral hygiene was applied. X-ray and CBCT examinations were made and implant marginal alveolar bone loss (MBL) was measured 3, 6, 9, 12 months after loading with Planmeca PROMAX3D software. Besides, 3, 6, 9, 12 months after loading, improved plaque index (iPLI), modified bleeding index (mBI) and probing depth (PD) were also recorded. SPSS 15.0 was applied to analyze the data. Result Differences in diastolic and systolic blood pressure and changes in heart rate in patients during the intraoperative period were (8.86 ± 0.31) mmHg(1 mmHg=0.133 kPa), (19.18 ± 0.22) mmHg, (20.19 ± 1.84) times/min, which were significantly lower than those of the control group values [(16.55±1.08) mmHg, (28.31±2.30) mmHg, (20.19±1.84) times/min] (P<0.05 or 0.01);at 12 months after the load around the implant in oral health management group, the values of MBL and mSBI were 2.6 (2, 4), 2.1 (2, 4), which were significantly better than control group [4.3(3, 7), 4.3(3, 7)] (P<0.01);simultaneously, there was significant difference in the values of MBL and PD between experimental group (1.42 ± 0.03, 0.77 ± 0.24) and control group (1.59 ± 0.04, 0.54 ± 0.17) (P<0.01). Conclusion Well-performed health management of peri-implant could reduce the MBL and keep healthy soft tissue environment around implants.

Objective To develop a recognition method of liver steatosis degree on type-B ultrasonic images based on multi-fractal spectrum texture analysis method and pattern recognition. Methods Features of singularity strength width and multi-spectrum area were extracted from the curve of multi-fractal spectrum of each liver ultrasonic images. These two features and the feature of mean intensity ratio comprised a three-dimensional feature vector, which would be classified by BP neural network. Results The classification accuracy was 96.00% for normal liver, 80.00% for mild fatty liver, 88.00% for moderate fatty liver and 92.00% for severe fatty liver. Conclusion Feature vector combined with BP neural network can identify the steatosis degree of liver on the ultrasonic images and can be used as an assistant diagnostic method.

Resident standard training for traditional Chinese medicine(TCM) is an important part of medical training, after-department examination plays the role of its quality control. Through the construction of question database for after-department examination, combining TCM residency standard training requirements and actual situation of the department, it contribute to the formation of standardized examination,improve the system of resident standardization training for TCM, help to training appropriate and qualified TCM residency.

Objectiye To explore the expression of COX-2 and VEGF and its clinical significance in non-Hodgkin lymphoma (NHL). Methods The expression of COX-2 and VEGF were detected by immunohistochemistry in 42 cases of NHL and 20 cases of lymph node with benign pathological change. Results The positive rate of COX-2 and VEGF was 45.24% and 73.81% in NHL respectively. The expression rate of VEGF was positively correlated with that of COX-2 in tissues of NHL ( x2 = 4. 63, P ＜ 0. 05).The expression of COX-2 was related to clinical stage and histopathologic grade of NHL ( x2 = 5.43, P ＜0. 05), but it had no association with gender, age, B symptoms, and IPI. The expression of VEGF was significantly related with aggression, B symptoms and IPI ( x2 =8. 979, 8. 893,6. 434, P ＜0. 05), but it had no association with age, gender and clinical stages. Conclusion COX-2 and VEGF may be involved in NHL tumorgenesis, and COX-2 may accelerate angiogenesis by increasing VEGF expression. Specific COX-2 inhibitors may be a novel therapeutic approach for NHL.
