Anaplastic thyroid cancer (ATC) is the most aggressive thyroid tumor, with lower morbidity and higher mortality rates. Radical surgery could improve local control and survival rates. Conformal radiotherapy is superior to conventional radiotherapy, which could improve the patients’ quality of life. There are a few chemotherapeutic drugs against ATC, and the outcome of chemotherapy alone is modest. Concurrent chemoradiotherapy can prolong the survival. Targeted therapy brings new hope for refractory patients. Many cancer centers are exploring surgery, radiotherapy, chemotherapy, targeted therapy and other biological treatment of comprehensive application, in order to enhance the curative effect. This article reviewed the foregoing treatments for ATC.

BACKGROUND: As a kind of filling material for wedge-shaped defects, GC Fuji Ⅸ glass-ionomer cement has arose more and more attention. However, the comparison of repair results between GC Fuji Ⅸ glass-ionomer cement and reinforced glass-ionomer cement are poorly understood. OBJECTIVE: To compare the clinical effect of GC Fuji Ⅸ glass-ionomer cement and reinforced gtass-ionomer cement for repairing wedge-shaped defects of old people. METHODS: Totally 80 teeth were randomly divided into 2 groups, and filled by GC Fuji Ⅸ glass-ionomer cement (experimental group) and reinforced glass-ionomer cement (control group), respectively. The clinical effect of 2 materials were evaluated on color match, edge density heterozygosity, restoration integrity, occurrence of secondary caries and pulp symptom at immediately, 3 months, 6 months and 1 year after placement. RESULTS AND CONCLUSION: The color match of the experimental group was better than that of the control group at 3 months, 6 months and 1 year after placement (P < 0.05); and the edge density heterozygosity of the experimental group was superior to the control group at 6 months and 1 year after placement (P < 0.05); in addition, the restoration integrity of the experimental group was surpass the control group at 1 year after placement (P < 0.05). It demonstrated that GC Fuji IX glass-ionomer cement is an ideal choice for wedge-shaped defects of old people, which exhibits superior effects to reinforced glass-ionomer cement in 1-year follow-up.

The effects of Trichostatin A (TSA) on histone deacetylase 8 (HDAC8) expression, proliferation and cell cycle arrest in T-lymphoblastic leukemia cell line Molt-4 cells in vitro were investigated. The effect of TSA on the growth of Molt-4 cells was studied by MTT assay. Flow cytometry was used to examine the cell cycle. The expression of HDAC8 was detected by using immunocytochemistry and Western blot. The results showed that proliferation of Molt-4 cells was inhibited in TSA-treated group in a time- and dose-dependent manner. The IC50 of TSA exposures for 24 h and 36 h were 254.3236 and 199.257 microg/L respectively. The cell cycle analysis revealed that Molt-4 was mostly in G0/G1 phase, and after treatment with TSA from 50 to 400 microg/L for 24 h, the percents of G0/G1 cells were decreased and cells were arrested in G2/M phase. Treatment of TSA for 24 h could significantly inhibit the expression of HDAC8 protein in Molt-4 cells (P<0.01). It was concluded that TSA could decrease the expression of HDAC8 in Molt-4 cells, which contributed to the inhibition of proliferation and induction of cell cycle arrest in Molt-4 cells.

Objective To investigate the clinical features,critical laboratory parameters,and fetal monitoring methods in intrahepatic cholestasis of pregnancy(ICP).Methods A retrospective analysis of 21 cases of ICP suffered with fetal death in Women's hospital.School of Medicine.Zhejiang University from January 1999 to December 2010 were discussed.Results(1)The average age of ICP patients suffered with fetal death were(30.2±4.6)years old.Among them,4 cases were older than 35 years,six cases were multipara.oneo of them suffered stillbirth 2 year before.Twenty cases were singleton pregnancies and 1 cage was twin pregnancy.(2)All 21 cases of fetal death occurred in the third trimester,12 cases occurred before 37 weeks,9 cases after 37 weeks.Nine cases were diagnosed by ultrasound in outpatient clinics,fetal heart beat disappeared in 9 patients after admission because of ICP, two disappeared after labor, one during anesthesia before emergent surgery. Perinatal mortality rate of ICP was 0. 148% (21/14 184), and fetal death occurred from 29 to 41 weeks with an average gestational age of ( 33.8 ± 4. 2 ) weeks, ( 3 ) Puritus occurred in all 21 cases while 11 of them had pruritus all over the body. Ten pregnant women felt the fetal movement decreased or disappeared before diagnosis of fetal death. The glycocholic acid levels increased in all of the 21 cases. Among them, glycocholic acid levels in 11 cases were (21.49 -64. 48) μmol/L, while in 10 cases were ≥64. 48 μmol/L Serum bile acid levels elevated in 16 cases which had been analyzed ( the other 5 cases had not been checked ), and the highest level reached 270 μmol/L Serum alanine aminotransferase and aspartate aminotransferase were increased in 14 cases. Seven cases had their total bilirubin ＞21 μmoL/L, and 12 cases had their direct bilirubin levels significantly elevated. Among the 21 cases of ICP, 15 cases were in severe status, while the other 6 cases were mild. (4) Nine patients had no antepartum surveillance since fetal death were diagnosed before admission. The results of antepartum surveillance were as follows: 2 cases had nonreassuring nonstress test (NST), one had mild "V" type deceleration. Absence of diastolic flow in umbilical artery were found in 3 cases, and low fetal biophysical score was got in one case. ( 5 ) All 21 patients had vaginal delivery. Six of them delivered after natural contraction, and the remaining 14 cases delivered after oral intake of mifepristone and amniotic injection of ethacridine, or oxytocin induced labor within 48 hours, only one case delivered after additional dinoprostone suppositories. The appearance of fetus, placentas and membranes were normal, the lengths of umbilical cord were average. Four cases were found with cords binding the necks or the bodies. Eighteen cases had grade Ⅲ amniotic fluid with meconium-stained, and 2 cases complicated by oligohydramnios. Ten cases had their fetuses and placentas examined by pathologist. Among them, one case had multiple malformations, no more obvious pathological abnormalities were found in other fetuses. Pathologic examination showed that fibrin deposited around chorion and deciduas basalis, large vessels accompanied by calcification, degeneration,hemorrhagic infarction, and increased focal syncytial nodules could be seen in all of the ten placentas. Conclusions Fetal death in pregnant women with ICP of ten occurs after the contractions, Severe ICP may be a key factor that involved in the occurrence of fetal death. Up to now, there is no valid indicators in fetal monitoring, which can predict fetal death. Extensive assessment of the severity and careful antepartum surveillance should be achieved before timely termination of pregnancy.

Objective To investigate the effects of substance P (SP) on the expression of apoptosis-associated genes in fibroblasts derived from pathological scars. Methods Fibroblasts derived from keloid, hypertrophic scar and normal skin were cultured separately in media containing SP and SP receptor antagonist. PCNA, bcl-2 and bax protein in fibroblasts were assessed by means of immunohistochemistry. Results SP enhanced PCNA and bcl-2 expression in all three kinds of fibroblasts, whereas, bax expression was inhibited significantly. SP inhibited the expression of bax in keloid scar fibroblasts (KSFB) more remarkably than that in hypertrophic scar fibroblasts (HSFB) or normal fibroblasts (NFB), and the effect was stronger on HSFB than on NFB. SP receptor antagonist could inhibit those effects of SP totally or partially. Conclusion SP may play an important role in the formation of pathological scars by modulating the expression of apoptosis-associated genes, which is mediated by SP receptor.
