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 assess the feasibility and accuracy of the transvaginal three-dimensional hysterosalpingo-contrast sonography(3D HyCoSy) on the fallopian tube patency. Methods 3D HyCoSy was performed in twenty-two cases with infertility. Image quality of 3D HyCoSy was evaluated. The estimate of the fallopian tube patency in 3D HyCoSy were compared with those of hysterosalpinography(HSG) in one week. Results The mean score of image quality of 3D HyCoSy in twenty-two cases was 2. 8 + 0. 5. The accuracy of the unobstructed and obstructed fallopian tube were 88.9% (24/27) and 94.1% (16/17) respectively, and the total accuracy was 90. 9% (40/44) , which was equal to the results of HSG (P = 0. 000,k = 0. 812). No adverse reactions of SonoVue occurred in the cases. Conclusions Transvaginal 3D HyCoSy which is a new imaging technique can safely and effectively display the morphological character of fallopian tube and assess the patency.

Objective To explore the ultrasound performance and related factors on the role of normal living rabbit's liver by laser ablation. Methods The rabbit's liver tissue were ablated by Echolaser integrated laser interventional ultrasound system, and the necrosis of the lesion and performance of pathology and anatomy were observed. Results The outline of the lesion was ellipse like. The two-dimensional US showed regular hyperecho area in the center, mild strong echo in the peripheral and mild attenuation backward. Contrast enhanced ultrasound (CEUS) showed a filling defect of contrast media in the ablated area. After dissection, the center of the lesion was slag-like carbon, the peripheral was necrosis area; HE staining showed: the center of the lesion was cavity like and dye-free,peripheral area was irregular red staining, the surrounding area was infiltrative inflammatory cells. Different power and time leaded to differences of the ablative effect and lesion size:the more power and time,the bigger of the ablative size. The ablative effect and lesion size was stable in 3 W 10 min and 5 W 6 min groups and caused the complete necrosis of the zone, there existed statistical differences among the two groups. Conclusions Laser ablation can cause fast, precise, effective and safe necrosis of the liver tissue, and the more power and time, the bigger of the ablative size.

Objective To investigate the occurrence of regular and rare types of beta thalassemia in Guangxi,and to reduce the misdiagnosis and missed diagnosis.Methods Between Jan 2010 and Dec 2013,42 770 patients (20 740 males and 22 030 females,one month to fifty-four years old) from Maternal and Child Healthy Hospital of Guangxi,who were suspected with thalassemia were involved in this study.All these patients were went through the following screening tests:routine blood cell count,hemoglobin electrophoresis test,and serum iron and ferritin tests.Positive patients in the screening test would be taken gene diagnosis with regular reverse dot blot (RDB) method; negative patients in gene diagnosis but positive in the screening test would be under the test of beta globin gene sequencing.Results Totally 28 101 patients were confirmed with thalassemia from 42 770 suspected patients,including 10 891 patients with beta thalassemia,49 patients were homozygous,10 718 patients were heterozygote,and 124 patients were compound heterozygous.After beta globin gene sequencing test,14 regular mutations in people of south China and 7 rare types mutations were detected,the detection rate of rare type of beta thalassemia was 17.949％ (7/39).Conclusions Mutation spectrum of beta thalassemia in Guangxi is complex.Gene diagnosis of rare type thalassemia needs to be done in patients with phenotypes of thalassemia and negative of regular gene diagnosis,in order to reduce misdiagnosis,and improve accuracy of clinical diagnosis.
