Objective To systematically the efficacy of transcatheter arterial chemoembolization (TACE) conbined with percutaneous microwave coagulation therapy (PMCT) in treatment of advanced liver cancer.Methods A search was performed by retrieving the domestic and foreign literature database,including WanFang Data,VIP,CNKI,PubMed,Cochrane Library,CBM,EMBASE,Medline,between January 2005 and May 2015.These documents were about the analysis of the efficacy of TACE combined with PMCT in treatment of advanced liver cancer,including complete response(CR),partial response(PR),total effective rate,the levels of AFP declining,1,2,and 3 year survival rate and all the trials must be randomized controlled trials.Meta-analyses were conducted using the Cochrane Collaboration's RevMan 5.2 software.Results Fourteen documents were retrieved,including 989 patients,conbined treatment group 470 patients,simple treatment group 519 patients.The results of Mete-analysis shows that the total effective rate of TACE combined with PMCT is higher than TACE alone in treatment of advanced liver cancer.AFP declining ＞ 50％ of TACE combined with PMCT more obvious than TACE alone.1,2,and 3 year survival rate of TACE combincd with PMCT higher than TACE alone.These differences were statistically significant.Conclusion TACE combined with PMCT might be more effective than TACE alone in treatment of advanced liver cancer.

Objective To investigate the expression of Oct-4 as a stem cell marker in gastric carcinoma tissues and its clinical significance. Methods From June 1996 to March 2006, 63 paraffin samples of gastric carcinoma tissues were obtained, and the expression of Oct-4 was examined by immunohistochemical staining. Another 58 normal tissues adjacent to gastric carcinoma and 10 normal gastric mucosa tissues were served as controls. The clinieopathologieal data of 63 patients with gastric carcinoma were retrospectively analysed, and their relationship with the expression of Oct-4 was analysed. Fifty of these 63 patients were followed up for 8 years, Kaplan-Meier method and Log-rank teat were employed to explore the correlation between Oct-4 expression and survival, and Cox Regression analysis was performed to evaluate the possibility of Oct-4 expression as an independent prognostic factor for gastric carcinoma. Results The positive expression rate of Oct-4 in gastric carcinoma tissues was 80.95% (51/63), significantly higher than that of normal tissues adjacent to gastric carcinoma (5.2%, 3/58) and normal gastric mucosa tissues (0) (P < 0.01). The expression of Oct-4 was positively correlated to the clinical stage of gastric carcinoma(P<0.01). There was no significant difference in the expression of Oct-4 among patients with different differentiation, age, and gender (P>0.05). Patients with higher expression of Oct-4 had significantly shorter survival time (P<0.05). The expression of Oct-4 was not significantly correlated with the prognosis of gastric carcinoma(RR, 0.554; 95% CI, 0.209-1.466). Conclusion The expression of Oct-4 is correlated with the clinical stage and survival time of patients with gastric carcinoma, however, it is not an independent prognostic factor for gastric carcinoma.

Objective To investigate the clinical characteristics of hospital infection and the pathogen type,distribution and drug resistance,in the intensive care unit of our hospital,to direct proper antibiotics use and supply the scientific basis for hospital infection control. Methods The clinical data of 392 inpatients in our intensive care unit from April 2008 to March 2010 were monitored prospectively and analyzed retrospectively. Results Of the 392 impatients,78 cases had hospital infection (19.89% 78/392),112 time-case infection (28.57% 112/392). The most common infection was the main respiratory tract infections accounted for 54.46% (61/112) ,followed by urinary tract infections accounted for 15. 19% ( 17/112 ), blood infection accounted for 11.61% (13/112). 152strains pathogens were identified in the study,in which G- bacilli accounted for 69.7%, G+ bacteria accounted for 17. 8% and fungi accounted for 12.5%. Main pathogens such as acinetobacter baumannii ,pseudomonas aeruginosa,klebsiella pneumoniae, staphylococcus aureus showed multiple drug resistance in different degrees. Conclusions Intensive care unit has a high nosocomial infection rate,lower respiratory tract infection is the most frequent type and the main pathogens have different degrees of multi-drug resistance. Standardized, rational use of antibiotics,prevention of the multi-drug resistant bacteria spread may help to reduce the occurrence of hospital infection in intensive care unit.

Objective To investigate the diagnosis,preoperative examination and surgical treatment of carotid body tumor(CBT).Methods From December 2008 to December 2012 80 patients of carotid body tumor were treated in our center.The average age was(43:±:12)years,33 cases were male,47 cases were female.The lesions were unilateral in 68 cases and bilateral in 12.All tumors were surgically resected.In 26 of Shamblin Ⅰ,32 of Shamblin Ⅱ and 19 of Shamblin Ⅲ tumors were simply resected.One Shamblin Ⅱ and 2 Shamblin Ⅲ cases underwent tumor resection combined with external carotid embolization.3 Shamblin Ⅱ and 8 Shamblin Ⅲ cases were treated by tumor resection combined with internal carotid reconstruction,1 Shamblin Ⅲ was done with tumor resection combined internal carotid repair.Results All of 80 patients with 92 tumors were successfully resected.There was no death case during peroperative period,while one case developed hemiplegia and 14 cases suffered cranial nerve injuries.68 cases (85％) were followed-up from 1 year to 6 years.Thera were 14 patients with cranial nerve injuries,2 of them were lost to follow-up,11 with complete or partial recovery and 1 was still doing poorly.Conclusions Tumor size and its relation to the carotid artery form the basis upon which appropriate operation is adopted.

Objective To study the (-)-epigallocatechin-3-gallate (EGCG) function on the proliferation of T cells derived from the peripheral blood and synovial fluid of rheumatoid arthritis (RA) and RA-related cytokine levels and the role of EGCG on RA synovial fibroblasts (FLS) proliferation was investigated. Methods ① Mononuclear cells from RA peripheral blood (30 cases) and synovial fluid (23 cases)were isolated. Blank group, negative control group, positive control methotrexate (MTX) group and therapeutic group with three different concentrations of EGCG were set up. Incorporated isotope 3H was used to test T cell proliferation from RA-PBMC and SFMC. ELISA assay was used to test cytokine (TNF-α, IFN-γ, IL-1, IL-6 and IL-17A) levels. ② MTT assay was used to test FLS proliferation from RA synovial tissue (8 cases).Results ① The CPM value of the high-dose group of EGCG in the peripheral blood and synovial fluid of RA patients was [ ( 15 136±2910), ( 11 587±3135 ) ], which was declined significantly than the control group (42856±2127) (P＜0.01). The levels of TNF-α, IFN-γ, IL-1, IL-6 and IL-17A in the high-dose group of EGCG in the peripheral blood were [(321±13), (298±20), (132±12), (197±7), (59±8) pg/ml], which were decreased significantly than those of the control group [ (458±28), (505±26), (346±28), (405±25),(109±13) pg/ml ] (P＜0.05 or P＜0.01 ). The levels of TNF-o, IFN-γ, IL-1, IL-6 and IL-17A in the highdose group of EGCG in the synovial fluid were [(41.4±2.9), (182±16), (56.3±11.0), (34.2±1.9), (44±8)pg/ml ], which was decre-ased significantly than the control group [ ( 388.3± 19.3 ), (469±20), ( 104.2±17.8 ),( 114.5±4.8), ( 104±11 ) pg/ml] (P＜0.05 or P＜0.01 ). ② The level (A) of the high-dose group of EGCG in the FLS was (0.08±0.02), which was declined significantly than the blank group (0.27±0.04) (P＜0.05).Conclusion ① In vitro EGCG can inhibit T cell proliferation from peripheral blood and synovial fluid of RA patients and the TNF-α, IFN-γ, IL-1, IL-6 and IL-17A secretion are decreased. ② In vitro EGCG can inhibit the proliferation of RA FLS.

Objective To investigate the injury characteristics and prognostic risk factors of patients with craniocerebral injury so as to provide some suggestions for the improvement of medical prevention,intervention and treatment measures.Methods Trauma database system was applied to collect the medical records of 661 patients with traumatic brain injury admitted to the Department of Neurosurgery of 105th Hospital of Hefei in 2009.Their general conditions,injury characteristics and outcomes were analyzed and the risk factors affecting their outcomes were investigated by Logistic regression analysis.Results Of the patients with craniocerebral injury,the males accounted for 70％ (463/661).The patients at 45 years old or so had the highest incidence of craniocerebral injury.Patient number in the second half of one year was 1.65 times more than that in the first half of one year (412/249 ).Most patients were injured from traffic accidents (87.7％,580/661 ) and 512 patients (77.5％) suffered from multiple injuries.ISS,injury causes,age and injury incidence quarters showed close correlation with the final outcome.Conclusions The patients with craniocerebral injury demonstrates distinctive characteristics in aspects of gender,age,incidence time,injury causes,and multiple injuries,but the ultimate outcomes are related to the injury severity,injury causes,age and other factors.

BACKGROUND: According to up-to-date development, the best timing to repair cleft palateis at 9-12 months old after birth when the articulation does not begin to develop.However, there are many over-eight-year-old children who still suffer from unrepaired cleft palate. Therefore, it is veryimportant to adopt proper surgery for these patients to improve palate form and articulatory function. OBJECTIVE: To study the characteristics of the cleft palate in patients of over 8 years old and the effects of palate repair and posterior pharyngeal flap transplantation (PPFT) on articulation. DESIGN:A controlled study with children patients as subjects. SETTING: Department of Maxillofacial Surgery, Medical College of Stomatology, Fourth Military Medical University of Chinese PLA PARTICIPANTS: Twenty-four children patients of cleft palate who were treated in the Department of Maxillofacial Surgery ,Medical College of Stomatology, Fourth Military Medical University of Chinese PLA from January 2000 through December 2003 were enrolled in the study. Fourteen were male and ten female. Their ages varied from 8 to 20 years old (mean 13.8 years). Three cases were bilateral complete cleft palate and twelve cases were unilateral complete cleft palate. Nine were incomplete cleft palate. METHODS :Two flap palatoplasty and upper pedicle PPFT were conducted in all the patients. In thirty days after surgical treatment, the patients were asked to repeat the words of a doctor in the phonetic lab with his or her lips 10 cm away from microphone. The words of the patients were recorded and evaluated subjectively by 5 doctors specialized in pathologic phones. MAIN OUTCOME MEASURES :The palatopharynx was observed with nasopharyngoscope before and after operation. And the improvement of nasal gas leakage and enhanced rhinophonia were also evaluated. RESULTS: The repaired cleft palate was healed in the first intention in all the patients. The soft palate retreated satisfactorily and the palatopharynx was apparently closed, which created good preconditions for articulation. The patients' articulation was also improved in different degrees. All the 24 patients had the fourth grade of enhanced rhinophonia and nasal gas leakage before repairing. After palate repair and PPFT, the enhanced rhinophonia and nasal gas leakage of grade 1 was in 3 patients, grade 2 in seven, grade 3 in six and grade 4 in eight patients. CONCLUSION: The combination of palate repair and pharyngoplasty is able to improve the form of soft palate and the articulation of over-eightyear-old patients with cleft palate.

Objective To explore the value of Ligasure vessel sealing system(LVSS)during resection of retroperitoneal tumor.Methods Group 1 including 32 cases were performed resection of retroperitoneal tumor with LVSS and electrosurgical seapel from Jun.2004 to Oct.2008.group 2 including 26 cases were done with electrosurgieal seapel from Jan.2001 to Jun.2004.Operating blood loss,operating time,iatrogenic injury,postoperative blood loss and hospital stay were compared between the two groups.Results There was no significant difference in hospital stay[(11.7±0.7)d vs.(12.3±1.4)d)]and iatrogenic injury(9.38%vs.16.00%)between two groups statistically(P＞0.05),but the intraoperative blood lose[(403.1±37.1)ml vs.(704.0±129.0)m1)s,postoperative blood loss[(131.5±18.4)ml vs.(214.8±29.2)ml)]and operating time[(166.5±8.9)min vs.(186.8±15.4)min]were less in group 1 than that in group 2(P＜0.05).Conclusion Ligasure vessel sealing system has advantages of safe coagulation,shortening operation time in resection of retroperitoneal tumor.
