OBJECTIVETo summarize the experience and investigate better method on treatment of high-grade soft tissue sarcomas of crura in youth.

METHODSSix young cases suffered from high-grade soft tissue sarcomas of crura were treated by interpolatory chemotherapy using vindesine 4mg or vincristine 2 mg combined with cisplatin 40 - 60 mg and 4'-Epidoxorubicin (4'-epi-ADM) 50 - 80 mg. There were 3 males and 3 females, and their ages rang from 12 to 23. The primary tumor locations were: calf in 4, thigh in 1, popliteal fossa in 1. The pathological type of these 6 cases were: 1 small round cell tumor from soft tissue, one rabdomyosarcoma, one alveoliar soft part sarcoma, one synovial sarcoma, one primitive neuroectodermal tumor and one without classification. All cases received interpolatory chemotherapy twice. Before their receiving interpolatory chemotherapy they had no tumor metastases. The maximum diameters of tumors rang from 4 - 15 cm. One patient's tumor disappeared after interpolatory chemotherapy and she received no further therapy. The other 5 cases received operations and one of them received additional pre-operational radiotherapy using Co(60) and pre-operational systemic chemotherapy using ifosfamide and dacarbazine.

RESULTSThe tumors dwindled in size of 1 - 8 cm after interpolatory chemotherapy. All cases saved their crura and had normal functions. After interpolatory chemotherapy, all patients suffered from edema and ache of crura. One patient suffered from lymphatitis. All these patients were followed up for 6 - 20 months. All of them were alive and had pigmentations on their crura. A lung metastasis was found in 1 patient by CT 2 months after surgery, then he was in hospital and treated by chemotherapy.

CONCLUSIONSFor treatment of high-grade soft tissue sarcomas of crura which are difficult to resect in youth, interpolatory chemotherapy is a good choice.

OBJECTIVETo analyze the impact of radical surgery with different extent of lymph nodes dissection on the prognosis of colorectal carcinoma patients and to see if lymph nodes adjacent to mesenteric artery root should be excised.

METHODSData of 1409 cases with colorectal carcinoma treated in Shanghai Cancer Hospital during 1985-2000 were collected. These patients had primary colorectal carcinoma treated by radical surgery with different extent of lymph nodes excision. They were divided into two groups: in group D3 the lymph nodes adjacent to mesenteric artery root were excised (n = 857), while in group D2 (n = 552) were not. The time of follow-up was 6 approximately 289 months (median: 48 months).

RESULTSThe 1-, 3-, 5-, 10-year total survival rates (TS) in group D3 patients were 90.3%, 81.4%, 77.0% and 73.0%, respectively. The 1-, 3-, 5-, 10-year tumor-free survival rates (TFS) in group D3 patients were 89.9%, 79.4%, 74.5% and 70.3%, respectively. In group D2 patients, the 1-, 3-, 5-, 10-year TS were 91.04%, 84.12%, 79.33% and 76.17%, and those of TFS were 90.0%, 82.7%, 76.0% and 71.8%, respectively. The differences in TS and TFS in the two groups of patients were not significant according to Kaplan-Meier analysis (P > 0.05). During the follow-up period, 42 patients in group D3 had local recurrence (4.9%), while in group D2 the rate of local recurrence was 5.4% (P > 0.05). Metastases developed in 79 cases in group D3 and in 60 cases in group D2 (P > 0.05). Multivariate analysis revealed that the excision of lymph nodes adjacent to mesenteric artery pedicle did not statistically correlate with recurrence, metastasis and survival time after radical operation of colorectal cancer.

CONCLUSIONExcision of lymph nodes adjacent to the mesenteric artery root has no significant impact on prognosis and is unnecessary in the radical surgery for colorectal carcinoma.

OBJECTIVETo explore the therapeutic principles and prognostic factors of soft tissue sarcoma.

METHODSTwo hundred and fifty-one patients with soft tissue sarcoma (STS) treated at Shanghai Cancer Hospital during 1986 - 1990 were reviewed retrospectively.

RESULTSThe 1-, 3-, 5-, 10-year tumor-free survival rates were 67.74%, 57.16%, 52.41%, 38.60%, respectively. The overall survival rates for 1, 3, 5 and 10 years were 81.01%, 67.75%, 60.79%, and 49.23% respectively. Log-rank test showed that the patients with different pathological findings, histological grades, mass location and size, anatomical depth, and surgical margin showed different outcomes. Whether the sarcomas invaded the vessels or metastasized would influence the survival rates. The patients who underwent different interventions or operations also had different outcomes. The prognosis of STS was associated with age, histological type, histological grade, tumor size, surgical margin and metastasis according to the Cox regression analysis.

CONCLUSIONDuring the treatment of STS, wide-resection, especially 3-dimensional resection, comprehensive treatment and individualized treatment should be advocated.

Objective To study the differences in 24 h ambulatory blood pressure of healthy young men between the plateau and the plains.Methods A total of 100 young men were enrolled in this study.They underwent 24 h ambulatory blood pressure monitoring on the plateau and on the plains respectively.The data was analyzed by SPSS.17.Results The 24 h mean systolic blood pressure (24HMSBP) and diastolic blood pressure (24HMDBP),day (6:00-22:00) mean systolic blood pressure (DMSBP) and diastolic blood pressure (DMDBP),night (22:00-6:00) mean systolic blood pressure (NMSBP) and diastolic blood pressure (NMDBP),24 h mean heart rate (24MHR),HRmax,HRmin,24 h systolic blood pressure load (24HSBPL) and diastolic blood pressure load (24HDBPL),day (6:00-22:00) systolic blood pressure load (DSBPL) and diastolic blood pressure load (DDBPL),night (22:00-6:00) systolic blood pressure load (NSBPL) and diastolic blood pressure load (NDBPL) were significantly different between the plateau and plains (all P ＜ 0.05).However,the systolic blood pressure decrease rate (SBPDR) and the diastolic blood pressure decrease rate (DBPDR),day systolic blood pressure coefficient of variation (DSBPCV) and diastolic blood pressure coefficient of variation (DBPCV),night systolic blood pressure coefficient of variation (NSBPCV) and diastolic blood pressure coefficient of variation (NBPCV) were not significantly different (P ＞ 0.05).Conclusion The systolic blood pressure (SBP)and diastolic blood pressure (DBP) on the plateau are significantly higher than those on the plains.24HMDBP and DMDBP increase more significantly on the plateau than those of SBP.The blood pressure load (BPL) on the plateau is higher than that on the plains,with a higher degree of dispersion,so are the 24 h mean heart rate (24MHR),HRmax,and HRmin.

Chronic enteritis can produce an excess of reactive oxygen species resulting in cellular damage. Stanniocalcin-1(STC-1) reportedly possesses anti-oxidative activity, the aim of this study was to define more clearly the direct contribution of STC-1 to anti-oxidative stress in cattle. In this study, primary intestinal epithelial cells (IECs) were exposed to hydrogen peroxide (H2O2) for different time intervals to mimic chronic enteritis-induced cellular damage. Prior to treatment with 200 microM H2O2, the cells were transfected with a recombinant plasmid for 48 h to over-express STC-1. Acridine orange/ethidium bromide (AO/EB) double staining and trypan blue exclusion assays were then performed to measure cell viability and apoptosis of the cells, respectively. The expression of STC-1 and apoptosis-related proteins in the cells was monitored by real-time PCR and Western blotting. The results indicated that both STC-1 mRNA and protein expression levels positively correlated with the duration of H2O2 treatment. H2O2 damaged the bovine IECs in a time-dependent manner, and this effect was attenuated by STC-1 over-expression. Furthermore, over-expression of STC-1 up-regulated Bcl-2 protein expression and slightly down-regulated caspase-3 production in the damaged cells. Findings from this study suggested that STC-1 plays a protective role in intestinal cells through an antioxidant mechanism.

OBJECTIVETo detect the disparity of three cytokines interleukin-6 (IL-6), interferon-inducible protein 10 (IP-10) and interleukin-17 (IL-17) in peripheral blood (PB) and synovial fluid (SF) of patients with juvenile idiopathic arthritis (JIA).

METHODSerum concentrations of the three cytokines were measured in 27 patients with 13 systemic-onset JIA (sJIA), 14 polyarticular JIA (pJIA) and 28 healthy controls using enzyme-linked immunosorbent assay (ELISA). Nineteen patients with no marked arthritis symptom or only temporary arthralgia were enrolled in probable sJIA group. SF from 18 patients with 7 sJIA, 11 pJIA were examined for cytokine levels.

RESULT(1) The statistically significant difference in serum IL-6 was detected between sJIA and healthy control group [28.0(4.2-59.2) ng/L vs. 12.3 (2.1-13.8) ng/L, P < 0.05], but no significant difference between probable sJIA and healthy control group [11.8(7.7-39.2) ng/L vs. 12.3 (2.1-13.8) ng/L, P > 0.05] was found. There were statistically significant differences between sJIA group and healthy control group in serum concentrations of IL-17 [14.0(9.8-34.3) ng/L vs. 9.8 (7.9-16.2) ng/L, P < 0.05], yet compared to healthy control group, no significant difference in concentration level of IL-17 was found in pJIA Group [14.2(9.9-16.9) ng/L vs. 9.8(7.9-16.2) ng/L, P > 0.05].(2) In sJIA and pJIA SF, the median IP-10 level was significantly higher compared to respective PB levels [619.7 (160.9, 873.1) ng/L vs. 64.8 (27.4-111.9) ng/L;660.9 (401.9, 1349.8) ng/L vs. 97.4 (41.9-222.1) ng/L, P < 0.01, respectively], but there was only significant difference in IL-17 between pJIA SF and PB [22.9 (17.1, 45.8) ng/L vs. 14.2 (9.9-16.9) ng/L, P < 0.01].

CONCLUSIONIL-6 may play more important role in the pathogenesis of sJIA. Moreover, IL-6 may be the biomarker associated with arthritis in early JIA stage. Both autoinflammation and autoimmune response may be involved in the pathogenesis of sJIA. IL-17 enrichment may only occur in local joint, the levels of IL-17 in PB may not be significantly increased. The prominent expression gradient between SF and PB of IP-10 maybe the basis of performing chemotaxis and further causing joint damage.

Objective To survey the prevalence rates of adult carotid atherosclerosis in water-sourceoriginated high iodine area in Shandong province in 2008 and discuss the relationship between water-sourceoriginated high iodine and carotid atherosclerosis occurrence. Methods Yuncheng county was chosen as observation area which included Dachenlou, Weigai, Liuyi and Ershilipu villages. Juye county was chosen as control that included Zhangxi, Bihainan, Xiaguan and Qiji villages. Two hundred and ninety-nine participants aged over 40 from water-source-originated high iodine areas and 323 residents aged over 40 from normal iodine areas were investigated.Portable-type B mode color Doppler was performed to examine the carotid artery of all participants. The adult carotid atherosclerosis was diagnosed and graded through the ultrasonograms. Results The prevalence rates of adult carotid atherosclerosis in the 4 water-source-originated high iodine villages of Dachenlou, Weigai, Liuyi and Ershilipu were 47.1% (33/70) ,62.2% (51/82) ,67.5% (52/77) and 58.6% (41/70), respectively and the prevalence rates of adult carotid atherosclerosis in the 4 normal iodine villages of Zhangxi, Bihainan, Xiaguan and Qiji were 40.7%(35/86),40.8% (31/76),38.2% (34/89) and 37.5% (27/72), respectively. The prevalence rates of adult carotid atherosclerosis standardized by age in the 4 high iodine villages and the 4 normal iodine villages were 45.81% ,58.18% ,61.63%,55.34% and 34.66%,36.25%,43.01% ,41.30%, respectively. The prevalence rates were higher in high iodine villages than that in control villages(T = 26, P ＜ 0.05 ). There were 136 people scored "0", 120 people scored "1 -3",43 people scored "4 - 7", and total 299 people. There were 201 people scored "0", 87 people scored "1 - 3", 35 people scored "4 - 7", and total 323 people. The expected prevalence rates and severity of adult carotid atherosclerosis was significantly different between high iodine area and normal iodine area (x2 = 17.54,18.42, all P ＜ 0.01).Conclusion The prevalence rate and severity of adult atherosclerosis in water-source-originatod high iodine area is higher than that in normal iodine area.

OBJECTIVETo analyze the clinical and cytogenetic features of myelodysplastic syndrome(MDS) associated with del(20q).

METHODSThe cytogenetic profiles, clinical manifestations, laboratory data, and transformation in course of disease were analyzed.

RESULTS(1) Of 29 MDS patients with del(20q), eleven (37.9%) had normal karyotype in addition to del(20q) aberration. Among them, nine patients were categorized into refractory anemia(RA)/RA with ringed sideroblasts(RAS) group and two into RA with excess Hasts(RAEB)/RAEB in transformation(RAEB-T) group. The breakpoint in 20q11 was commonly seen in patients with RA/RAS(63.2%), while del(20q12) was predominant in patients with RAEB/RAEB-T(accounting for 70% in all RAEB/RAEB-T patients). It was observed that RAEB/RAEB-T patients had higher frequencies of extra chromosomal aberrations(50%) and complex karyotype(30%) than did the RA/RAS patients (26.3%, 5.3% respectively); (2) Almost all patients revealed prominent pancytopenia, dyserythropoiesis and dysgranulopoiesis and 58.6% patients showed dysmegakaryopoiesis; positive periodic acid schiff staining of nucleated erythrocytes or reduction of neutrophils were found in 62.5% of patients; 81.8% of patients expressed lymphoid antigens; (3) Two cases transformed to acute myeloid leukemia.

CONCLUSIONDel(20q) may be an early and primary cytogenetic event in the development of hematologic malignancies. Pancytopenia and dysplasia of bone marrow cells are prominent in patients with MDS associated with del(20q); lymphoid antigen expression is a common occurrence; more additional chromosomal abnormalities and complex karyotypes appear when the disease becomes worse.
