AIM: To investigate the clinicopathological features of orbit primary liposarcoma. METHODS: By means of histological, ultrastructural and immunohistochemical studies, the clinical and pathological features of two cases of orbit primary liposarcoma were analyzed and compared with 6 cases of primary retroperitoneum liposarcoma. RESULTS: Two cases of orbit primary liposarcoma were young persons. The majority of cases of primary retroperitoneum liposarcoma were aged over 40 years. The tumors were located at the retrobulbar region, and involved the wall of eyeball and optic nerve. The tumor cells of case 1 were round, with abundant eosinophilic granules in the cytoplasm, and there were lipoblasts in the tumor cells of two cases. Local recurrence following excision occurred in case 2.Immunohistochemical expression of S100 protein was positive in all cases, and CK (AE1/AE3), desmin, MyoD1, melanoma were negative. Ultrastructure observation showed lipid drops in the tumor cells in case 2 of orbit primary liposarcoma. CONCLUSION: Primary liposarcoma of the orbit may recur.The diagnosis was based on histological,ultrastruc-tural observation and immunohistochemical staining.

OBJECTIVE:To observe therapeutic efficacy and safety of S-1 capsules combined with recombinant human end-ostatin in the treatment of middle and advanced primary liver carcinoma. METHODS:Totally 94 patients with middle and advanced primary liver carcinoma in the First College of Clinical Medical Science of China Three Gorges university during Feb. 2012-Dec. 2014 were divided into combination group(48 cases)and control group(46 cases)according to random number table. Both groups were given S-1 capsules 40-60 mg orally within 30 min after breakfast and supper. Combination group additionally received Recom-binant human endostatin injection 150 mg added into 0.9%Sodium chloride injection 210 mL with portable micro pump for continu-ous pump of 120 h. A course involved 14 d treatment and 7 d interval. Short-term objective therapeutic efficacy,clinical benefit re-sponse (CBR) and ADR were evaluated after 2 courses. Disease progression time and average survival period were compared be-tween 2 groups. RESULTS:Objective response rate,disease control rate,disease progression time and average survival period of combination group were 14.6%,66.7%,(5.5 ± 1.3) months,(10.7 ± 3.8) months;those of control group were 8.7%,45.6%, (4.8±1.2)months,(8.9±3.3)months,with statistical significance between 2 groups(P<0.05). CBR rate of combination group (79.2%)was significantly higher than control group(52.2%),with statistical significance(P<0.05). There was no statistical sig-nificance in the incidence of ADR between 2 groups (P>0.05). CONCLUSIONS:S-1 combined with recombinant human end-ostatin show good therapeutic efficacy and tolerance for patients with middle and advanced primary liver carcinoma,and do not in-crease the incidence of ADR.

Objective To investigate the clinical pathologic significance of lymphangiogenesis in in colorectal cancer. Methods New lymphatic-specific markers D2-40 was used immunohistochemically to detect the lymphatic vessel density(LVD) in the intratumoural and peritumoral areas, and in normal tissue from 96 cases of colorectal cancer, which were analyzed with clinical pathologic parameters of those colorectal cancer. Results Significandy higher LVD was found in the intratumoural area(14.5±2.4), when compared with normal(5.9±1.1)and peritumoural areas(6.7±1.2) (P<0.01). LVD of the peritumoural area was higher than normal area (P< 0.01). However, peritumoural LVD was associated with both depth of invasion and liver metastasis (r=0.71,0.78 P<0.05), but not associated with tumour size, macroscopic type and lymph-node metastasis (P>0.05). Intratu-moural LVD was not correlated with tumour size, macroscopic type, the depth of invasion,lymph-node metastasis, and liver metastasis(P>0.05). Conclusion Lymphangiogenesis in the peritumoural area may be helpful in evalution of liver metastasis and prognosis.

Objective To estimate the impact of universal salt iodization on child intelligence quotient (IQ) development in Hainan province. Methods In this is a cross-section study from September in 2008 to April in 2009,the observation group was historical iodine deficiency ward which includes 2 counties and 6 townships,and the control group was non-historical ward which includes 6 counties and 9 townships. Comparison of child IQ distribution according to different geographical housing position(plain,mountainous area,coast),age and sex based on the result of urine iodine examination and the IQ test of children between 8 and 10 years old. Results The median of urinary iodine of children in the observation group was 196.2μg/L which was 2.13 times of the urinary iodine median in the control group(91.9μg/L). The average IQ of children in the observation group was 94.7 which was 8.5 higher than the control group(86.2) ; IQ≤69 rate in this group was 7.7%(91/1179),and it was 8.9 percentage point lower than the control group[16.6%(253/1520)]; IQ≥ 110 rate of the group was 18.3%(216/1179),and it was 10.0 percentage point higher than the control group[8.3%(126/1520)]. The average IQ of children living in mountainous area(83.1) was the lowest in the control group. It was 3.5 and 5.1 lower than that of the children living in the plain(86.6) and coastal area(88.2) respectively; the IQ≤69 rate of children living in mountainous area [20.5%(91/443)]was the highest,and it was 3.8 and 7.1 percentage point higher than that of the children living in the plain [16.7% (89/533)]and coastal areas [13.4% (73/544)]respectively. The average IQ of children aged 8 (97.4) was similar to those aged 9(95.9) in the observation group which was 6.8 and 5.3 higher than that of the children aged 10(90.6) in the same group respectively; However,the average IQ of children aged 8,9 and 10 was close in the control group(86.8,86.3 and 85.6). The average IQ of boys(96.2) was 3.1 higher than that of the girls(93.1),and their IQ≤69 rate[6.3%(37/590)]was 2.9 percentage point lower than that of the girls[9.2% (54/589)]in the observation group. On the other hand,the average IQ(87.2) of boys was 2.1 higher than that of the girls(85.1),and IQ≤69 rate[14.5%(114/787)]was 4.5 percentage point lower than that of the girls [19.0%(139/733)]in the control group. The average IQ of children with different housing geographical position,age and sex in observation group was 5.0-12.4 higher than that of the control group; their IQ≤69 rate was 7.7-13.2 percentage point lower than that of the control group; their IQ≥110 rate was 5.6-13.0 percentage point higher than that of the control group. Conclusions Supplementing salt iodization can improve child intelligence. Supplementing iodine can increase the child IQ and reduce the child mental retardation.

ObjectiveTo investigate clinical risk factors and coronary angiographic features in young men with acute myocardial infarction (AMI).MethodsWe retrospectively studied 200 young men with AMI and compared with 104 non-CHD men,89 old men with AMI.All patients were admitted to hospital from January 2009 to December 2010 and undergone coronary angiography,and the clinic and coronary angiographic features were assessed.The relation between body mass index (BMI),smoking history,familial history of early coronary artery disease,essential hypertension,type 2 diabetes mellitus,hyperlipidemia,serum uric acid ( UA),lipids,hemoglobin (Hb),fasting blood glucose (FBG) with coronary artery disease and its severity was observed.The severity of CAD was diagnosed by the number of diseased vessel.Results In young men with AMI group,the factors such as smoking history,obesity,essential hypertension,type 2 diabetes mellitus,familial history of early coronary artery disease were remarkably different ( P ＜ 0.05 ) ; body mass index,fasting blood glucose,total cholesterol,triglyceride,low density lipoprotein cholesterol were higher than the control group ( P ＜ 0.05 ),hemoglobin was lower than the control group ( P ＜ 0.05 ).Applying Logistic regression analysis,obesity ( OR =11.020),type 2 diabetes mellitus ( OR =5.805 ),essential hypertension ( OR =4.428 ),familial history of early coronary artery disease ( OR =2.883 ),smoking history ( OR =2.153 ) and lower concentration hemoglobin ( OR =1.034) are independent risk factors (P ＜ 0.05) for young men with AMI. According to coronary angiography in young men with AMI,there were 14 cases with zero-vessel disease,109 cases with singlevessel disease (54.50％,69 cases involved with left anterior descending artery) and 42 cases with twovessel disease,35 cases with three-vessel disease.The ratio of single vessel disease involved left anterior desending artery in young men was higher than that of old men with AMI ( P ＜ 0.05 ).Conclusions Obesity,type 2 diabetes mellitus,essential hypertension,familial history of early coronary artery disease,smoking history and lower concentration of hemoglobin are risk factors of young men with AMI ; Single vessel coronary disease is seen more frequently in young men with AMI.

Objective To build the theoretical system model and research assessment indicators for equalization of basic medical and health services of both urban and rural residents.This aims at providing a theoretical and empirical basis for advancing basic medical health system covering rural and urban residents.Methods Literature research and Delphi expert consultation are used to build the indicator model and structure.The extremal standard method,health resources sharing by geography method,Gini coefficient method and other statistical analysis were used for an empirical analysis and test in an eastern provincial capital city.Results The indicator system comprises three dimensions of opportunity,process and result,as well as seven second-level indicators of health financing,resource allocation,accessibility etc.and twenty-seven third-level indicators.The grand mean value of the urban and rural regional indicators for H city in 2010 was calculated as 63.53,while the mean values for urban and rural were 74.75 and 45.58 respectively.Conclusion The assessment indicators focus on three combinations:basic public health services and basic medical services,service supply and demand,as well as the number and quality of services.This approach can help with the assessment of equalization of basic medical and health service for urban and rural areas and policy making.

Objective To evaluate the cause of ischemia related to myocardial bridge (MB) by using SPECT/CT MPI and CTCA.Methods A total of 294 patients with chest pain,tightness or palpitation undergoing both CTCA and MPI were retrospectively enrolled in this study from March 2008 to March 2013.Among them,49 patients (26 males,23 females,age:32-85 (55.4± 16.6) years) had MB.Locations of MB and myocardial ischemia were recorded.Fused MPI/CTCA was analyzed.If there was no mural atherosclerotic plaque-related stenosis on CAG at the same location of coronary artery where ischemic myocardium was found,then MB was considered as the ischemic cause.Myocardial ischemia rates of different MB locations were compared by x2 test.Results Among 49 patients with MB,3 cases had MB in proximal segment of LAD,34 in mid LAD,4 in distal LAD,3 in septal branch,2 in distal LCX,1 in intermedius,and 2 in mid RCA.There were 41 cases with myocardial ischemia.Myocardial ischemia in 32 cases was caused by MB,including 23 caused by MB in mid LAD.The myocardial ischemia rates of the most common MB location (mid LAD,n =34) and other locations (n =15) were not significantly different (67.6％ (23/34) vs 60.0％ (9/15),x2 =0.27,P＞0.05).Conclusions MB is commonly found in the mid LAD.The myocardial ischemia rates caused by MB is not related the MB location.Hybrid MPI/CTCA could evaluate the sites of coronary MB and myocardial ischemia simultaneously and therefore may be useful to evaluate the relationship between MB and myocardial ischemia.
