Synovial sarcoma is a rare tumour found in soft tissue; it is a mesenchymal spindle cell tumour that is not related to the synovial membrane. This tumour has a low incidence, and the most frequent place of occurrence is the lower extremities in young adults. Synovial sarcoma of the head and neck accounts for 3%-5% of sarcomas in this anatomical region. The tumor in the nasal cavity is less than 1%. The treatment of choice for synovial sarcoma of the head and neck is complete surgical excision of the tumour mass followed by adjuvant radiotherapy.

Objective To evaluate total laparoscopic splenectomy combined with pericardial devascularization. Methods In this study,40 patients with portal hypertension and hypersplenism underwent total laparoscopic splenectomy combined with pericardial devascularization,in which 26 cases had a history of up-GI bleeding. Results Procedures were successful in 36 patients.There was four conversions to open surgery.The operations were completed in a mean time of (224 ± 54) min,with a mean estimated blood loss of (296 ± 209) ml and with no serious complication. Conclusion Total laparoscopic splenectomy combined with pericardial devascularization is a safe and effective available minimally invasive procedure in patients with portal hypertension and hypersplenism.

Objective To treat scalp lacerations by using the hair apposition technique (HAT) and to compare the HAT with standard suturing in a controlled prospective trial. Method Fifty patients with scalp lacerations were treated either by HAT or by standard suturing. Two groups were evaluated in consumed times for operation, pain sores, and complications. Results There were 30 HAT patients and 20 patients treated with suturing. The took shorter operation time consumed[(3.33 vs. (6.05 t = 4.85.P < 0.01], and HAT produced significantly lower pain score [(1.73vs. (3.20t = 4.01,P < 0.01]. There was a trend that more and more patients were willing to have HAT performed. Conclusions The advantages of HAT include a shorter time consumed for operation, less pain, satisfactory wound healing, and high acceptance by patients. HAT is acceptable for treating scalp lacerations in emergency room.

A total of 62 patients with radical operation of esophageal carcinoma were divided into all-in-one nursing intervention group (research,n =32) and routine nursing group (control,n =30).With regards to postoperative flatus time,removal of chest tube drainage time,postoperative hospital stay and hospital costs,the research group was lower than the control group (P ＜ 0.05).After 2 weeks,from the postoperative quality of life questionnaire with the European Organization for Research and Treatment of Cancer,the scores of overall health of enteral nutrition group were higher than those of parenteral nutrition group while the symptom scores of fatigue,nausea & vomiting,insomnia,decreased appetite,constipation and economic difficulties were less than parenteral nutrition group (P ＜ 0.05).Early postoperative enteral nutrition can improve the quality of life in patients with esophageal cancer.

AIM:To investigate the protective effect of nerve growth factor combined with Ginkgo biloba extract on retinal ischemia-reperfusion (RIR) injury in rabbits with experimental high intraocular pressure.METHODS:Establishment of rabbit glaucoma ischemia reperfusion model.Twenty-four New Zealand white rabbits were randomly divided into three groups:nerve growth factor group, Ginkgo biloba extract group and combination group.Respectively, in the continuous administration of 1, 7, 14d.We observed the morphological changes of the tissues of the retina.The levels of superoxide dismutase(SOD), nitric oxide(NO) and malondialdehyde(MDA) in retinal tissue were measured.RESULTS:Respectively, first, in the continuous administration of 1, 7, 14d, the contents of MDA and NO in Ginkgo biloba extract group and nerve growth group were higher than that in combination group (P<0.05).Secondly, the SOD content of Ginkgo biloba extract group and nerve growth group were lower than that of combination group at each time point (P<0.05).At each time point, the number of HE staining of retinal ganglion cells (RGCs) showed that the loss of RGCs in the combination group was significantly lower than that in the other groups, and the ganglion cell count showed that the Ginkgo biloba extract group and the neuronal growth group were lower (P<0.05).CONCLUSION:Nerve growth factor combined with Ginkgo biloba extract has better protective effect on retinal ischemia-reperfusion injury.The mechanism may be related to the decrease of free radicals and increase the activity of SOD in retinal tissue.

Objective To screen for the potential protein biomarkers in serum for the diagnosis of idiopathic Parkinson's disease (PD) using proteomic fingerprint technology. Methods Proteomic fingerprint technology combining weak cation exchange (WCX) magnetic beads with MALDI-TOF-MS was used to identify and compare the serum proteins from 61 patients with idiopathic PD, 29 patients with other neurodegenerative diseases (OND) and 30 healthy blood donors. Model of biomarkers and proteomics patterns associated with PD was analyzed by Biomarker Patterns Software. The model also was validated by 40 newly recruited PD cases. Results A total of 17 discriminating M/Z peaks which were related to PD were identified ( nonparametric test, Z:-4.039--2.633, P<0.01 ). Five biomarkers with M/Z of 6121, 5234, 2961,4309 and 8170 respectively generated an excellent model of distinguishing between PD and healthy groups. The sensitivity was 98.4% and the specificity was 83.1%. Blind testing in 40 newly recruited cases demonstrated a sensitivity of 85.0% (17 of 20 PD) and a specificity of 70. 0% (14 of 20 controls). Conclusions Combination of WCX magnetic beads with MALDI-TOF-MS is a useful method in establishing proteomic patterns associated with PD. It also may be used to construct a diagnostic model with PD Biomarkers. Although this model of biomarkers fails to distinguish between PD and OND controls, it is able to differentiate PD from healthy controls.

Objective To strengthen resource conformity of army hospital literature information resource, promote application development of information integration, and avoid the resource redundant construction and the information resource waste. Methods The architecture with data interchanges as platform was designed by Web Services technology based on optimization integration information resource of army literature and XML. Results Through optimization integration information resource of army literature, the platform architecture of literature information resource architecture with data interchanges as platform was completed. Conclusion The system can strengthen up information communication in army hospital systems and has practical significance for effective information organization, management and development.

OBJECTIVE:To prepare paeonol-HP-β-cyclodextrin (PAE-HP-β-CD) inclusion compound and to optimize its pre-scription technology. METHODS:PAE-HP-β-CD was prepared by freeze drying method and validated. Using inclusion rate as in-dex,main drug-accessory ratio,inclusion time,inclusion temperature and stirring speed as factors,the preparation technology was optimized by central composite design-response surface methodology. RESULTS:Prepared PAE-HP-β-CD underwent phase transfor-mation. The optimal inclusion technology was as follows as main drug-accessory ratio of 3.39∶1,inclusion temperature of 50 ℃, inclusion time of 3.2 h, stirring speed of 350 r/min. Relative error between measured value (87.46%) and predicted value (89.12%) of inclusion rate was 1.86%(n=6). CONCLUSIONS:PAE-HP-β-CD inclusion compound is prepared successfully, and its prescription technology is stable and feasible.
