The zinc finger protein A20 exists in many kinds of ceils in the body and plays multiple roles in physiological and pathological processes such as regulation of immune response,inflammatory diseases and cancers by inhibiting cell apoptosis induced by tumor necrosis factor (TNF) and restricting NFKB signaling pathway.Recently,the role of A20 in generation and development of tumors draws wide attention,hence,we summarized recent research progress of the relation between A20 and cancer in this review.

Objective To explore the reason of misdiagnosis and discuss the reoperation in thyroid carcinoma.Methods The data of 77 patients that had reoperation because of misdiagnosis were analyzed.Results The daignosis of all 77 cases were only based on pre-operative physical and uhrasound examination.The post-reoperative follow up (3～41 monthes):no case was found local recurrence.Conclusions The preoperative frozen section may avoid misdaignosis and the effect of reoperation for misdaignosed cases are satisfactory.

To ascertain current situation of wild Marsdenia tenacissima resources in Honghe, Yunnan province, the distribution, habitat characteristic and resources reserves of M. tenacissima were surveyed based on interviews and investigation. The results showed that M. tenacissima was found in 7 counties such as Jinping, Mengzi etc, and distributed mainly on the mountainsides from 800 m to 1 200 m. And distribution was affected by many factors, such as light, heat, topography, soil, and vegetation. M. tenacissima grew well in distribution areas. M. tenacissima had averagely a weight of 2.8 kg per plant. Resources reserve of M. tenacissima in Honghe was estimated to 1 300 tons by now but it reduced rapidly in resent years, the wild resources reserve may not meet demand of market. Resources protection and wildlife tending would be conducted to deal with increasing medication requirements.

OBJECTIVETo evaluate whether or not administration of folic acid and resveratrol have preventive effects on cleft palate formation as well as the comparison of the two drugs' s effects.

METHODSPregnant mice were randomly divided into 9 groups, with 8 mice in each group. The TCDD group mice were dosed with TCDD 28 microg/kg body weight on gestation day 10 (GD 10) animals in folic acid group were respectively dosed with folic acid 15, 10, 5 mg/kg and TCDD 28 microg/kg; resveratrol treated mice were divided into 3 groups: resveratrol 50 mg/kg were orally administered for 6 consecutive days, from gestational day GD 8 to GD13 in resveratrol (GD8-13 ) group; resveratrol 50 mg/kg were orally administered for 6 consecutive days, from gestational day GD 8 to GD13, followed hy an oral administered with TCDD on GD10 in resveratrol (GD8-13) + TCDD group; resveratrol 50mg/kg and TCDD 28 microg/kg were used by gavage administration at GD10 in resveratrol (GD10) + TCDD group. Control mice were treated with the same volume of water for 6 consecutive days from GD8 to GD13 and were given a single dose of corn oil on GD10. The pregnant mice weight and embryos, the number of live, cleft palate, dead and resorption fetal mice were recorded on GD 17.5. The coronal sections of the fetal mice heads were prepared at GD 17.5 and observed by microscopy.

RESULTSTotal frequency of clefts was 92.86% in TCDD group, 84.00% (15 mg), 73.08% (10 mg), 84.00% (5 mg) in folic acid + TCDD groups, 0% in resveratrol (GD10) group, 74.51% (GD10), 57.78% (GD8-13) in resveratrol + TCDD groups. The frequency of cleft was 0% in the control group. Compared with the control and the TCDD groups, there were significant differences in the number of live, dead and resorption fetal mice in TCCD + resveratrol (GD8-13) group (P < 0.05). No significant differences in embryonic weight, live fetuses weight, the number of live, dead and resorption fetal mice were found in the other groups (P > 0.05).

CONCLUSIONTest dose of folic acid and resveratrol both had certain antagonistic effect on cleft palate in mice induced by TCDD, with folic acid 10 mg/kg, resveratrol 50 mg/kg GD8-13 doses having stronger antagonistic action. Effects of both the two drugs have no significant difference, but resveratrol (50 mg/kg, GD8-13) significantly affects the fetal mice's growth and development under TCDD exposure in utero.

OBJECTIVETo explore the influence of conventional metal materials in oral cavity on brain magnetic resonance imaging (MRI).

METHODSFour kinds of metal materials (metal ligature wire, forging hard and slotless denture, casting nichrome denture, casting copper alloy denture) in oral cavity were scanned through MRI. FSE sequence T1 weighted imaging (FSE T1), EPI diffusion-weighted imaging (DWI) sequence of ordinary, Propeller DWI imaging were used.

RESULTSIn FSE T1 sequence, metal ligature wire and forging hard and slotless denture produced serious false image, casting nichrome denture produced moderate false image, casting copper alloy denture produced only little false image. In EPI DWI sequence, obvious magnetic-sensitive false image were produced in the dissection tissue of the brain by metal ligature wire. While in Propeller DWI sequence, magnetic-sensitive false image were greatly reduced and satisfactory images were formed.

CONCLUSIONDifferent metal materials in oral cavity have different influence on the MRI. The false images produced by different metal materials are closely related to the type of the material. Magnetic-sensitive false images can be eliminated by Propeller DWI technique.

Cholestatic liver injury,which is mainly caused by the disruption of bile acids,is common in the clinic.The pathogenesis of cholestatic liver injury is directly related to the changes of bile acid-related transporters,synthetic and metabolic enzymes.Nuclear receptors play a crucial part in cholestatic liver injury by regulating the expression of transporters and metabolic enzymes that maintaining the homeostasis of bile acids.In this review,we focus on the role of hepatic transporters and metabolic enzymes in cholestatic liver injury and the mechanism of nuclear receptors on the regulation of transporters and metabolic enzymes.

OBJECTIVETo investigate the effect of Jinleng undershorts on the elevated scrotal temperature induced by varicocele as well as on other clinical symptoms of the disease.

METHODSFifty-one varicocele patients received the treatment of wearing Jinleng undershorts for 30 min twice a day for a course of 90 days. Comparisons were made between the scrotal temperatures and other clinical symptoms of varicocele before and after the treatment.

RESULTSAfter 90 days of treatment with Jinleng undershorts, the left scrotal temperature of the varicocele patients was significantly reduced from (32.16 +/- 0.79) degrees C to (31.53 +/- 0.77) degrees C (P < 0.01), and the right scrotal temperature decreased from (31.91 +/- 0.73) degrees C to (31.81 +/- 0.63) degrees C (P > 0.05). Compared with pretreatment, significant improvement was found in such symptoms as wetness, fever and swelling of the scrotum, backache, headache, dizziness, fatigue and anxiety (P < 0.05), as well as in testicular pain (P < 0.01) and IIEF-5 score, which was increased from 15.89 +/- 6.13 to 20.04 +/- 3.87 (P < 0.01).

CONCLUSIONJinleng undershorts can be used for the treatment of mild and moderate varicocele.

OBJECTIVETo characterize oncogenic KIT signaling mechanisms in gastrointestinal stromal tumor(GIST), and to determine which signaling pathway might be of potential relevance to imatinib acquired resistance.

METHODSThe mutations of KIT and PDGFRa gene were evaluated and KIT downstream signaling profiles were evaluated in 8 specimen from 5 GIST patients who were evaluated treated between 2003 and 2008 in our hospital. Biochemical inhibition of the expression of related proteins in Ras/Raf/MAPK and PI3-K/AKT pathways, such as KIT, mitogen-activated protein kinase(MAPK),mammalian target of rapamycin(MTOR), AKT, Proliferating cell nuclear antigen (PCNA) and BCL-2, were determined by Western blotting for protein activation.

RESULTSThree cases who showed response to imatinib carried primary mutations in KIT gene, with 2 cases possessing mutation in exon 11, 1 case in exon 13. One case with imatinib-resistance developed KIT secondary mutation, but all the cases had no PDGFRa mutation. p-KIT and p-AKT expressions were higher in the samples of imatinib-resistant GIST than those of imatinib-responsive GIST. Total KIT, MAPK, p-MAPK, p-MTOR expressions were strong and comparable in all varied GISTs, which had no significant difference between imatinib-resistant and imatinib-responsive samples. PCNA and BCL-2 expression varied in samples of different therapy cycles and different location.

CONCLUSIONSRas/Raf/MAPK and PI3-K/AKT/MTOR pathways are essential to GIST pathogenesis. The KIT secondary mutation and PI3-K/AKT/MTOR pathway are particularly relevant for therapeutic targeting in imatinib-resistant GIST.
