Background Behcet's disease is a refractory panuveitis with high blindness rate.Multifocal electroretinography (mfERG) is a useful tool for the evaluation of the function of the posterior retina.ObjectiveThe aim of this study is to assess the characteristics of Behcet's disease using the mfERG.Methods mfERG was recorded in 68 eyes of 39 cases with active stage of Behcet's disease.All of the patients were diagnosed based on the Standard of International Study Group for Behcet's Disease and assigned to the cystoid macular edema (CME) group and the diffuse macular edema (DME) group after assessment by fundus fluorescein angiography (FFA).Seventeen normal subjects were used as controls.Oral informed consent was obtained from all of the subjects prior to this trial.mfERG recording followed the ISCEV Guidelines for Clinical Multifocal Electroretinography (2007 edition).The response density and latency of P1 and N1 waves in 6 rings were analyzed and compared.Results The amplitudes of N_1 waves from rings 1 through 6 and N1 wave from rings 1 through 5 were significantly declined in patients with Behcet's disease compared with normal control (P＜0.01).All of the latencies of P_1 waves from rings 1 through 6 were insignificantly shortened in patients with Behcet's disease compared with normal control (P＞0.05).The amplitudes of P_1 and N_1 waves from rings 1 through 6 in diffuse macular edema group were considerably lower than those in the cystoid macular edema group (P＜0.05,P＜0.01).A test of visual acuity showed a negative correlation to the amplitude and latency of N_1 wave (r=-0.36,-0.37,P＜0.05 ) and a positive correlation with the amplitude of N1 wave (r=0.43,P＜0.05) in the DME group.In the CME group,a test of visual acuity presented a negative correlation to the amplitude and latency of N1 wave and latency of P1 (r=-0.41,-0.35,-0.40,P＜0.05 ) and a positive correlation with the amplitude of P1 wave (r=0.48,P＜0.05).Conclusion mfEGR demonstrates that retinal electro-activity is abnormal in eyes with Behcet's disease.The distinct functional disorder is situated around the fovea.

Objective To investigate the clinical efficacy and safety of hyperthermic intraperitoneal perfusion chemotherapy (HIPC) in treatment of advanced colorectal cancer.Methods The Meta-analysis was applied to analyze 8 randomized controlled quantitative studies published at domestic and abroad.These patients treated by HIPC after radical operation with colorectal cancer were included for the treatment group,and those treated only by radical operation with colorectal cancer for the control group.Relative risk (RR) of outcome variable of 3-year and 5-year survival rate and safety between the two groups were compared.Results There were 8 selected literatures,including 1 501 cases,in which 765 cases for treatment group,and 736 cases for control group.RR of 5-year survival rate of the total patients was 2.39 (95% CI:1.66-3.45).RR of 3-year survival rate of the total patients was 2.13 (95% CI:1.45-3.13).The results demonstrated that HIPC could improve 5-year and 3-year survival rate,and sensitivity analysis confirmed the conclusions more reliable.The security was described in 5 literatures,the available information showed smaller potential security issue.Conclusions HIPC after radical operation of advanced colorectal cancer can increase 5-year and 3-year survival rate of patients,improve the prognosis of patients.Whether patients with increased incidence of postoperative complications related to the HIPC is no clear-cut conclusions for lack of related research.

OBJECTIVE To summarize the clinical experience of endoscopic thyroidectomy via suprasternal approach. METHODS Endoscopic thyroidectomy via suprasternal approach was performed in 35 patients with ultrasonic scalpel. RESULTS Operations were successfully performed in 35 patients. The mean operation times were 130 (105～190) minutes in 24 cases with subtotal lobectomy and 4 case with total lobectomy, 60 (50~70) minutes in 2 cases with isthmectomy, 228 (185～270) minutes in 2 case with bilateral subtotal lobectomy, 163 (140～215) minutes in 3 case with subtotal lobectomy and the contralateral ademona resection. The bleeding during operation was 5 to 40ml and the average hospital stay time was 4 (3～5) days. CONCLUSION Endoscopic thyroidectomy via suprasternal approach is a safe way with good cosmetic value.

OBJECTIVETo summarize the therapeutic experience in removing huge craniofacial hemangioma in 135 cases and reveal the rules of repairing the damaged tissues or organs caused by the extirpation.

METHODSThe procedure was to remove the focal lesion correctly, control hemorrhage, keep the stable blood volume, repair and rebuild the damaged tissues or organs reasonably.

RESULTSThe focal lesion was removed rather completely without accidental injuries or deaths. The damaged tissues or organs were repaired and rebuilt quite satisfactorily.

CONCLUSIONHuge craniofacial hemangioma of any type should be operated on as early as possible with sufficient preoperative preparations.

OBJECTIVETo study the therapeutic effect adenovirus-mediated apoptin gene transfer combined with ADM and CDDP on hepatocellular carcinoma in mice.

METHODSIn c57BL/ 6 mice bearing hepatocellular carcinoma, the changes of tumor volume, histomorphology, tumor inhibition rate and the side effects were observed after intratumoral injection of adenovirus containing apoptin gene and ADM and CDDP.

RESULTSSeven days after the treatment, the mean volume of the tumor in the mice receiving intratumoral apoptin-containing adenovirus injection combined with ADM and CDDP reduced significantly as compared with that in mice treated with adenovirus vehicle and control group. The tumor inhibition rate in the combined treatment group was 90.13%, significantly higher than that in the control group. No adverse effect of the treat was observed in the course of the experiment.

CONCLUSIONThe adenovirus vectors containing apoptin gene combined with ADM and CDDP may serve a safe treatment of hepatocellular carcinoma.

Objective To investigate the epidemiological information of patients in pre-hospital medical care for our large and medium-sized cities and probe the patients' characteristic. Method The data in 2008 were exported from the computer databases of 8 large and medium-sized cities' emergency medical centers in our country.The thorough records of data were conducted to statistical analysis. Results ( 1 ) The scheduling time, running time, rescue time, returning time, total time and service radius in the pre-hospital medical care group were 2.16± 1.10(min), 14.01 ±6.82(min), 12.12±5.96(min), 14.08± 6.85(min), 42.34± 20.21(min)and 8.50±4.18(km), and the above parameter in the non-death group were 2.19 ± 1.13(min), 14.15 ± 7.14(min),11.60±6.72(min), 14.92 ±6.89(min), 41.86± 19.53(minutes) and 8.63±4.31(Km), and the above parameter in the death group were 2.10± 1.08(min), 13.68 ± 7.14(min), 25.25 ± 12.34(min), 13.75±6.48(min), 54.74 ± 25.47(min) and 7.86± 3.91(Km), and the above parameter in the non-sudden cardiac death group were2.09± 1.03(min), 13.58±6.78(min), 25.53± 12.34(min), 13.60± 6.54(min), 53.79±23.77(min) and 7.67 ± 3.86(Km), and the above parameter in the sudden cardiac death group were 2.12 ±1.02(min), 14.10±7.05(min), 24.79± 12.08(min), 13.79±6.61(min), 54. 80 ± 25. 36( min) and 7.90±3.92(Km) respectively. The scheduling time, running time, returning time and service radius in the death group were less than those of the non-death group, but the rescue time and total time of the former were more than those of the latter respectively ( P ＜ 0.05 or P ＜ 0. 001 ). The scheduling time and returning time didn' t have significant difference between the sudden cardiac death group and the non-sudden cardiac death group respectively ( P ＞ 0.05), but the running time, total time and service radius of the sudden cardiac death group were more than those of the non-sudden cardiac death group, and the rescue time of the former was less than that of the latter respectively ( P ＜ 0.05 or P ＜ 0.001 ). (2)The patients' amount in pre-hospital medical care group, the non-death group, the death group, the non-sudden cardiac death group and the sudden cardiac death group were at most in first quarter, and the least time slice of patients' amount were 4:00～ 6:00, 4:00～6:00, 4:00～ 6:00, 22:00～ 24:00, 2:00～4:00 respectively, and the most time slice of patients' amount were 20:00～ 22:00, 20:00～22:00, 8:00～ 10:00, 2:00 ～ 4:00, 8:00 ～ 10:00 respectively. (3)In 241 876 cases of pre-hospital medical care group, the patients' amount of trauma was at most, whose age grades was by far among21 ～50, and the others in sequence were nervous system, circulatory system, other group, digestive system, respiratory system and poisoning group respectively, whose age grades in nervous system, circulatory system and respiratory system was by far above 51, especially above 70. The patients' age grades in other group and digestive system had two climax age groups, which the one was 21 ～ 30, and the other was above 70. The patients' age grades in poisoning group was by far among 21 ～ 50, which the patients' amount of acute alcoholism was at the most. (4) In 12 568 cases of death group, the death amount of circulatory system, other group, respiratory system, nervous system and digestive system ranked at the lst,2nd,4th,5th 8th respectively, whose age grades was by far above 51, especially above 70,and the patients' amount of sudden cardiac death was at the most in the death amount of circulatory system. The death amount of trauma and poisoning group ranked at the 3rd, 6th respectively, whose age grades was by far among 21 ～ 50. (5)The total amount, the death amount and the sudden cardiac death amount of male patients were more than those of female patients. (6)The percentage of the death group to the pre-hospital medical care group was 5.20%, and the percentage of the sudden cardiac death group to the pre-hospital medical care group was 1.29%,and the percentage of the sudden cardiac death group to the death group was 24.87 %, and the percentage of the sudden cardiac death group to the circulatory system group was 67.33 %. Conclusions ( 1 )The trauma and the sudden cardiac death are the overriding reason of disease and the overriding reason of death in our large and medium-sized cities respectively. (2) It is very important to cut the death rate of the middle-old age patients by strengthening prevention and cure of cardiovascular and cerebrovascular diseases, discerning the critical illness early and improving the level of pre-hospital medical care. (3)It is a strong method to decrease the total amount and the death amount of the trauma, especially in traffic accident, by strengthening safety in production, observing traffic regulation and enhancing the legal awareness.
