Objective To evaluate the feasibility and effectiveness of combination chemotherapy with etoposide and cisplatin(EP)regimen on the patients with high-risk,chemorefractory and recurrent gestational trophoblastic neoplasia(GTN).Methods Thirty-nine patients with gestational trophoblastic tumors were analyzed retrospectively,25 of 39 patients were of high-risk,9 patients were chemorefractory and 5 patients were recurrent.All 39 patients were administrated with EP regimen,and 10 patients were assisted with surgery.All the patients were followed up.Clinical response,toxicity,the occurrence of secondary tumors of all patients,and the fertility of 30 patients whose fertility function was preserved were investigated. Results Thirty-nine GTN patients underwent a total of 221 cycles of the EP regimen.The average number of courses for each patient was 5.7.The total complete remission rate of the regimen was 74%(29/39). Twenty-five patients with high-risk GTN received a total of 139 cycles and the average number of courses was 5.6.Nineteen patients achieved complete remission and 6 patients showed drug-resistant.The complete remission rate of the high-risk group was 76%(19/25).Nine patients with chemorefractory GTN obtained a total of 55 cycles and the average number of courses was 6.1.Six patients achieved complete remission and 3 patients showed drug-resistant again.The complete remission rate of the chemorefractory group was 6/9. Five patients with recurrent GTN received 27 cycles and the average number of courses was 5.4.Four patients achieved complete remission,1 patient showed drug-resistance and died.Bone marrow toxicity, gastrointestinal reaction and alopecia were the main side effects of the EP regimen,but the bone marrow toxicity was slight and no grade Ⅳ side effect occurred.No fatal effect was found.Eight of 30 patients whose fertility faction was preserved had become pregnant after recovery,with a total of 8 pregnancies.Among them,2 were terminated by induced abortion,and 6 underwent normal term delivery and gained 6 infants who had no congenital malformation.All the 6 children had normal growth and development after childbirth. None of the women developed secondary tumors.Conclusion The EP regimen is effective and safe for the treatment of high-risk,chemorefractory and recurrent GTN.

OBJECTIVE: To observe the origin, course and diameter of the metatarsal nutrient artery. METHODS: The metatarsaL nutrient in 90 feet, ranging in age from newborn to 87 years, were studied by perfusion method. The origin, course and diameter of these arteries were observed and measured. RESULTS: The diameter of the metatarsal nutrient artery was 0.24 approximate, equals 0.30 mm. The nutrient arteries of the first metatarsal bone originated from the deep plantar branch and the first metatarsal plantar artery in 59.6% of specimens, while the nutrient arteries of the other metatarsal bones mainly originate from the plantar metatarsal arteries, the plantar arch and its perfora-ting branches. The diaphysial nutrient foramina were situated in the middle third of the shaft over 90% of specimens. CONCLUSION: The metatarsal nutrient artery showes practical significance in clinic.

OBJECTIVEThe aim of this paper was to evaluate the treatment outcome of multimodal treatment for 196 patients with locoregional recurrent esophageal cancer after curative treatment and to determine the prognostic factors of recurrence.

METHODSOne hundred and ninety six patients with locoregional recurrent esophageal cancer curatively treated in our hospital were included in this study. Kaplan-Meier method was used to analyze the survival rate. Log rank test was used to evaluate the difference between the groups. Multivariate survival analysis was conducted using a Cox proportional hazard regression model with a backward stepwise procedure.

RESULTSThe overall 1-, 2- and 3-year survival rates were 29.8%, 5.9% and 4.0%, respectively, with a median survival time of 8.0 months. The univariate analysis showed that ECOG PS, the interval between initial treatment and recurrence, the regimens of initial treatment and retreatment were independent prognostic factors. The multivariate analysis showed that the regimens of initial treatment and retreatment were independent prognostic factors. Retreatment methods significantly influenced the survival. The median survival time of chemoradiotherapy, radiation therapy alone, chemotherapy alone, EGFR-TKI and best supportive care were 13.0, 7.0, 6.0, 4.0 and 3.0 months, respectively (P = 0.000).

CONCLUSIONSThe prognosis of patients with locoregional recurrent esophageal cancer after curative treatment is poor. The main prognostic factors are the regimens of initial treatment and retreatment. Multimodal treatment including radiotherapy and chemotherapy may improve the long-term survival of the patients.

Objective To investigate epidemical situation of drinking-tea fluomsis in Qinghai province, in order to understand diet structure to provide the scientific basis for the prevention and control and the scientific research. Methods In 2007, according to "Scheme for Survey on Epidemical Drinking-tea Fluorosis", we carried out an customized investigation in 28 counties, 3 townships sampled in each county, 2 villages in each township, 50 adults and 50 school-age children in each village; at same time, 1 monk temple was sampled in each county, 50 clergy adults and 50 children in each temple. Then we investigated the resident income, the diet structure, the brick tea consumption and so on, and applied Dean method to diagnose dental fluorosis. The patient number estimated based on the survey result. Results ①Yeady per capita income of people was mostly 500 - < 1000yuan, next 1000 - < 3000 yuan; economic income in pasturing area was higher than that of agriculture, half area and half agriculture and half pastoral region and township. ②Staple food was bread flour primarily in the animal husbandry agricultural half pastoral area,next were the roasted barley and the rice;the bread flour was the principle food in the agricultural region and the cities,next were the rice and the roasted barley;among non-staple food,meat came fimt and milk foHowed,egg the last.③The frequently edible vegetables Was potato.cabbage and greenpepper,eaten by a majority of people[62.82%(6497/10 343)];as for fruits,apple,pear and orange was primarily consumed,75.95%(7856/10 343)of people ate less than 10 times every month.④Sixty-one thousand nine hundred and ninety-nine residents were registered,153 335 kg ofbrick tea was consumed in villages and towns,2.47 kg per person;in 1001 monks investigated,4120 kg of brick tea was consumed every year,4.12 kg per person.⑤Detection rate of adult dental fluorosis in the villages and towns was 24.11%(2494/10 343),that of the children was 24.38% (3012/12 355);detection rate of dental fluorosis in monks was 26.13%(203/777),that of the children was 39.73% (89/224).⑥Detection rate of adult skeletal fluorosis in villages and towns was 15.60%(17/109);that of monks was 4.88%(2/41).⑦The 95%confidence limit estimated a total number of dental fluorosis patients were 1 084 306- 1 134 170 persons.the median Was 1 109 238 persons;the 95% confidence limit estimated a total number of skeletal fluorosis patients were 309 177-758 199 persons,the median was 533 688 persons.Conclusions Qinghai province has a great quantity of brick tea consumption,having lots of people with drinking-tea fluorosis which is in severe degree.The resident food structure was monotonous and mostly transpolted from other region.

OBJECTIVETo explore the influence of ischemia/reperfusion (anoxia/reoxygenation) on immunofunction of endothelial cells (ECs) and effect of intervention with Yisheng injection (YSI, a pure natural medicine) on it.

METHODSModel of ECs induced by anoxia/reoxygenation was established to mimic ECs ischemia/reperfusion injury in vivo with human umbilical vein endothelial cell line ECV304. Then YSI was used to intervene the anoxia/reoxygenation process. Nuclear transcriptional factor-kappa B (NF-kappa B) was exhibited by fluorescent staining, HLA-ABC, HLA-DR, CD86 and CD54 were detected by flow cytometry. Mixed endothelial cell-lymphocyte reaction (MELR) was conducted to examine the proliferation of lymphocyte, production of IL-2 and percentage of apoptotic lymphocyte.

RESULTSAnoxia/reoxygenation made the ECV304 cell became round, shrunk and abscised, with increased plasma NF-kappa B, and changed from positive cytoplasm to positive nucleus. HLA-ABC, HLA-DR and CD86 on surface of cells increased but CD54 showed unchanged. MELR showed the incorporation of 3H-TdR and production of IL-2 increased significantly and the percentage of apoptotic lymphocyte decreased. After YSI intervention, the ECV304 cell shaped recovered, NF-kappa B expression didn't down-regulated, but the percentage of positive cells decreased, changed to positive dominant. Besides, reversal changes were shown in other parameters.

CONCLUSIONAnoxia/reoxygenation influences some important immune related molecules in ECV304 cells, YSI could antagonizing these influences to maintain the immune function of endothelial cells in a relative normal manner.

OBJECTIVETo investigate the protective effects of 15-methyl-lipoxin A4 (LXA4) on mesangioproliferative nephritis in rats and the possible mechanisms.

METHODSMesangioproliferative nephritis was induced by a single intravenous injection of the mouse monoclonal anti-Thy1.1 antibodies (ER4) in 20 rats. Ten nephritic rats were injected with 15-methyl-LXA4 at 10 minutes before ER4 antibody injection and then 8-hourly until the rats were sacrificed on day 4 after nephritis induction. The nephritis was evidenced by presence of proteinuria, histologic examination with light microscopy, infiltrating leukocyte assessed by immunofluorescence microscopy, and mesangial cell proliferation assessed by proliferation scoring and by immunohistochemical staining of proliferating cell nuclear antigen (PCNA). Expressions of interleukin (IL)-1beta and IL-6 protein or mRNA in glomeruli were determined by radioimmunoassay or RT-PCR, respectively. Phosphorylated phosphoinositide 3-kinase (PI3-K), Akt1 and p27(kip1) in glomeruli were analyzed by Western Blot. Activities of nuclear factor-kappaB (NF-kappaB) and signal transducer and activator of transcription 3 (STAT3) in glomeruli were assessed by electrophoretic mobility shift assay (EMSA).

RESULTSThere were increases in glomerular infiltration of leukocyte, expressions of IL-1beta and IL-6 protein and mRNA, and activities of NF-kappaB in nephritic rats between days 1 and 4 after nephritis induction. The enhanced proteinuria, score of mesangial proliferation, glomerular PCNA positive cells, activities of phosphorylated PI3-K, Akt1 and STAT3, and reduced p27(kip1) expression were found on day 4 after nephritis induction. 15-Methyl-LXA4 treatment significantly reduced the proteinuria, glomerular infiltration of leukocyte, expressions of IL-1beta and IL-6 protein and mRNA, score of mesangial proliferation, glomerular PCNA positive cells, activities of phosphorylated PI3-K, Akt1, NF-kappaB and STAT3, and increased the p27(kip1) expression.

CONCLUSIONS15-Methyl-LXA4 can markedly inhibit the proteinuria, glomerular inflammation, and mesangial cell proliferation induced by anti-Thy1.1 antibodies. The inhibition effects are related to PI3-K/Akt1/p27(kip1)/cyclin pathway, STAT3 and NF-kappaB pathway-dependent signal transduction.
