Objective To study the pathogenic features, diagnosis and treatment of aberrant thyroid cancer.Methods A retrospective analysis of clinical and pathological data of 29 cases of aberrant thyroid cancer was made.Results All of the 29 patients underwent operative treatment and postoperative adjuvant radiation therapy and chemotherapy. On postoperative follow up, the 5-year survival rate was 52.0%. The longest survivor patient was alive 24 years after operation.Conclusions The key to increase the survival rate of patients is early detection and timely surgical treatment. Postoperative adjuvant radiation therapy and chemotherapy are conducive to increase survival rate.

0.5ug/ml in 34 patients(79.1%).Postoperative survival rate and recover of the work ability in group T were significantly higher than those in group C.Conclusions EPTT before RT for the type I diabetes patients with renal disorder can improve the results of RT.

Circadian rhythms are self-sustaining oscillations within biological systems that play key roles in a diverse multitude of physiological processes.The circadian clock mechanisms in brain and peripheral tissues can oscillate independently or be synchronized/disrupted by external stimuli.Dental enamel is a type of mineralized tissue that forms the exterior surface of the tooth crown.Incremental Retzius lines are readily observable microstructures of mature tooth enamel that indicate the regulation of amelogenesis by circadian rhythms.Teeth enamel is formed by enamel-forming cells known as ameloblasts,which are regulated and orchestrated by the circadian clock during amelogenesis.This review will first examine the key roles of the circadian clock in regulating ameloblasts and amelogenesis.Several physiological processes are involved,including gene expression,cell morphology,metabolic changes,matrix deposition,ion transportation,and mineralization.Next,the potential detrimental effects of circadian rhythm disruption on enamel formation are discussed.Circadian rhythm disruption can directly lead to Enamel Hypoplasia,which might also be a potential causative mechanism of amelogenesis imperfecta.Finally,future research trajectory in this field is extrapolated.It is hoped that this review will inspire more intensive research efforts and provide relevant cues in formulating novel therapeutic strategies for preventing tooth enamel developmental abnormalities.

OBJECTIVETo observe the clinical effects of Prunellae Oral Liquid (POL) on the size of thyroid with different states of thyroid function in patients of goiter.

METHODSFifty-six patients with hyperthyroidism, 24 with hypothyroidism and 18 with simple goiter were randomized into two groups. Group A treated by classical therapy, Group B by POL based on classical therapy. Size of thyroid of patients before and after treatment was measured by color ultrasonic Doppler and compared with the data obtained from 20 healthy subjects as control.

RESULTSSize of thyroid in all patients before treatment were obviously larger than that of normal control (P<0.01), but it reduced after treatment in both groups, especially in group B, in which it differed insignificantly to that in the normal control (P > 0.05).

CONCLUSIONCombined treatment of Chinese medicine (using POL) and Western medicine is superior to Western medicine alone in treating goiter with different states of thyroid function.

OBJECTIVETo investigate the relationship between the expression of COX-2 and liver cancer and construct a recombinant adenovirus encoding human COX-2 antisense RNA, and then to investigate its effects on liver cancer cell proliferation.

METHODSThe expression of COX-2 in 34 cases of hepatocellular carcinoma and in SMMC-7402 and SMMC-7721 cell lines was studied by using immunohistochemical techniques. The shuttle plasmid encoding anti-sense COX-2 was constructed by using cloning COX-2 cDNA fragment in the reverse direction into the pHCMVSPIA. Then the plasmid pJM17 and the shuttle plasmid were co-transferred into 293 cells with lipofectamine for homologous recombination to acquire recombinant adenovirus (Ad-AShcox-2), which was confirmed by PCR. Human hepatocellular carcinoma cell lines SMMC-7402 and SMMC-7721 were transduced in vitro. The cell apoptosis and cell cycle were analyzed by flow cytometry. The cell proliferation was determined by colony-forming efficiency.

RESULTSWe observed COX-2 expression in 82.4% of the hepatocellular carcinomas and SMMC-7402 cell line, but no COX-2 expression in the SMMC-7721 cell line. In addition, the recombinant adenovirus encoding anti-sense COX-2 fragment Ad-AShcox-2 was obtained with a titer of 1.06 x 10(12) PFU/ml. Ad-AShcox-2 reduced the expression of COX-2 and enhanced the percentage of cells into G1/G0 phase in the SMMC-7402 cell line. The difference of apoptotic index between the Ad-AShcox-2 group and the control group was statistically significant in SMMC-7402 but not in SMMC-7721. Similarly, colony-forming rates of SMMC-7402 and SMMC-7721 cell lines after Ad-AShcox-2 being transferred were (2.7+/-0.94)% and (33.6+/-4.24)%, respectively.

CONCLUSIONBy reducing the expression of COX-2 in hepatocellular carcinoma cells with the expression of COX-2, the cells could be inhibited.

AIMTo observe the effect of angiotensin-converting enzyme inhibitors (ACEI) and aldosterone receptor blockers on cardiac function to explore the mechanism of cardiac function descending and myocardial injury in calcium-overload rats.

METHODSCalcium-overload in rat was induced by administration of Vitamin D3 plus nicotine. To Estimate the extent of calcium-overload by calcium content. Angiotension II and aldosterone levels in the myocardia were measured by radioimmunoassay. Cardiac function (+/- LVdp/dt, LVESP and LVEDP) were measured by Powerlab. The malondialdehyde (MDA) content, activities of lactate dehydrogenase (LDH) and creatine kinase (CPK) were measured by biochemistry.

RESULTSCalcium content increased by 3.2-, 5.8 -fold in myocardial and artery, compared with controls. VDN-treated survivors showed lower + LVdp/dt(max) and -LVdp/dt(max) values, by 27% and 34%, respectively (both P < 0.01). Higher LVESP, and LVEDP by 42 % and 32% (P < 0.01); heart rate and mean arterial pressure were not significantly altered (P > 0.05). The lipid peroxidation products MDA and conjugated diene in myocardia were increased 22% (P < 0.01), 68% (P < 0.05) (P < 0.05), respectively. The plasma activity of CPK and LDH was greatly increased by 4.5-and 3.1-fold (P < 0.01), respectively. ACEI and spironolactone obviously relieved degree of calcium-overload and improved cardiac function and myocardial injury(P < 0.01). Calcium content in myocardia and artery was lower 44%, 39% and 57%, 34%. Lower MDA by 20%, 30%, lower conjugated diene by 44%, 35% than calcium-overload group. The plasma activity of CPK and LDH were obviously decreased 28%, 34% and 20%, 27%, compared with calcium-overload group.

CONCLUSIONCalcium-overload could lead to cardiac function descending and myocardial injury in calcium-overload rats by VDN. ACEI and spironolactone could reduce calcium-overload in myocardial and ameliorate cardiac function and decrease myocardial injury.

Objective: To explore the effect of 6 common cytogenetic abnormalities on the prognosis of multiple myeloma (MM). Methods: Myeloma cells from a cohort of 532 newly-diagnosed MM patients enrolled were enriched by CD138 immunomagnetic beads, then detected 13q-, 17p-, 1q+, t (4;14), t (11;14) and t (14;16) and other common genetic abnormalities in MM by using interphase fluorescence in situ hybridization (FISH) technique to compare the influence of different genetic abnormalities on their prognoses. Results: The rate of cytogenetic abnormalities was 78.20% (416/532) in 532 patients, of which 13q-accounted for 42.29% (225/532), 17p-16.35% (87/532), 1q+ 53.38% (284/532), t (4;14) 25.94% (138/532), t (11;14) 21.62% (115/532), t (14;16) 2.07% (11/532). Six kinds of cytogenetic abnormalities were analyzed, 13q- and 17p-, 1q+, t (4; 14), t (14;16) were all correlated (P <0.05). The univariate analysis indicated that 13q-, 1q+, t (4;14) and t (14;16) had a significant effect on progression-free survival (PFS), 13q-, 17p-, t (4;14) and t (14;16) had a marked influence on overall survival (OS). The multivariate analysis showed that 1q+, t (4;14) and t (14;16) were independent adverse factors of PFS, 17p-, t (4;14) and t (14;16) were independent unfavorable factors of OS. According to the independent prognosis factors number-based groups, the median PFS with 0, 1, 2, 3 independent prognosis factors of patients were 30.9, 28.4, 18.7 and 17.6 months (P =0.035) respectively, and the median OS were 54.4, 46.1, 38.0 and 21.2 months (P =0.004) respectively. Conclusion 1q+, 17p-, t (4;14) and t (14;16) were independent prognostic factors affecting the survival of MM patients. 13q-is often accompanied by 17p-, 1q + and (or) t (4;14) , simply 13q- was not an independent prognostic factor; the more number of independent prognostic factors, the worse the prognosis of patients.

Objective To investigate the role and mechanism of zinc finger protein 281(ZNF281)in high glucose(HG)-induced epithelial-mesenchymal transition(EMT)and extracellular matrix(ECM)synthesis in renal tubular epithelial cells(RTECs).Methods HG induced RTECs were used to construct a diabetic kidney disease cell model,and cells were divided into the control group,the HG group and the mannitol group.Cell proliferation viability was detected by CCK-8.The expression of ZNF281 was knocked down in HG-treated RTECs using small interfering RNA(siRNA).HG-induced RTECs after knockdown of ZNF281 were divided into the control group,the HG group,the HG+ZNF281 siRNA group and the HG+ZNF281 vector group.Adenosine monophosphate-activated protein kinase(AMPK)was activated using AMPK agonist,acadexin(AICAR),and then cells were divided into the control group,the HG group,the HG+AICAR group and the HG+dimethyl sulfoxide group.The expression levels of ZNF281,EMT and ECM synthesis-related indexes were detected by qPCR and Western blot assay.Results Compared with the control group,the protein and mRNA expression levels of vimentin,α-smooth muscle actin(α-SMA),fibronectin(FN)and collagen Ⅰ(Col Ⅰ)were significantly higher,and the expression of E-cadherin was significantly lower in the HG group.Compared with the HG group,the protein and mRNA expression levels of EMT and ECM synthesis-related indexes were significantly changed in the HG+ZNF281 siRNA group and the HG+AICAR group.The protein and mRNA expression levels of ZNF281 were significantly reduced in the HG+AICAR group compared with the HG group.In cells co-treated with AICAR and transfected with ZNF281 plasmid,the expression levels of vimentin,α-SMA,FN and Col Ⅰ were significantly higher in the AICAR+ZNF281 group,and E-cadherin was significantly lower compared with that of the vector group.Conclusion AMPK inhibits EMT and ECM synthesis in HG-treated RTECs by negatively regulating the expression level of ZNF281.
