[Objective]To analyze the clinical and biological characteristics of suspected malignant thyroid nodules associated with Hashimoto thyroiditis .To summarize different characteristics of benign and malignant nodules,diagnosis and treatment of suspected malignant nodules associated with Hashimoto's thy-roiditis. [Methods]Surgical y and pathological y confirmed, 58 cases of suspected malignant thyroid nodules associated with Hashimoto's thyroiditis were retro-spectively analyzed with clinical and pathological data. The differences of gender, age, number of nodules, calcification, and thyroid hormone and thyroid an-tibodies levels between malignant and benign nodules were compared from January 2009 to December 2011 .[Results] The average age of malignant thyroid nodules coexisting with HT group was significantly lower than that of benign nodules coexisting with HT group( P<0.05). The proportion of nodular calcifi-cation in malignant thyroid nodules coexisting with HT group was significantly higher than that in benign nodules coexisting with HT group( P<0.05). Pre-operative TSH and anti-TG levels in malignant thyroid nodules coexisting with HT group were significantly higher than that in benign nodules coexisting with HT group. Preoperative FT3, FT4, anti-TPO levels, sex ratio and number of lesions between the two groups were not statistical y significant. [Conclu-sions] The key point of preoperative diagnosis:patients of malignant thyroid nodules coexisting with HT are associated with youth, calcified nodules, elevated serum TSH and anti-TG levels.

Objective The purpose is to report the clinical result of repairing defection in hand surgery by using both the vascular tissue flap and external fixators. Methods The vascular tissue flap including bone flap and joint flap to repair the complex defection (soft tissue, bones and joints) in hand and forearm were applied in 9 cases. At the same time in surgery,injured bones and joints were fixed by A-O and mini external fixators in order to keep the non-injured joint actively and accelerate the cure of bones. Result All 9 cases were applied successfully with the all transplanted tissue survived. Pulling about the external fixator about 10- 12 weeks after surgery showed bone union and the f unction of hand recovered satisfactorily' Conclusion it is a reliable method for repairing the complex tissue defection in hand and forearm by combining external fixation of traumarology and microsugery technique. And it is also characterized by a minor injury in transplanted bones,early exercise for joints,flap circulation observed conveniently,and nursing easily.

Objective To explore the relationship between insluin resistance(IR)and plasma fibrinogen, blood lipids levels in patients with gestational diabetes mellitus (GMD).Methods Totally 127cases pregnant women in their 24 -28 gestational weeks were divided into GDM group(n =37),gestational impaired glucose tolerance test (GIGT)group(n =30)and normal glucose tolerance(NGT)group(n =60)based on the American Diabetes Associ-ation(ADA)2009 GDMdiagnostic standards.All selected cases's height,weight,fasting blood glucose (FBG),fasting insulin (FIN),blood lipids and fibrinogen(FIB)level were tested,and their body mass index(BMI)and IR index (HOMA -IR)were calculated.Results During the mid -trimester,the levels of BMI,FIB,HOMA -IR,FBG,FIN, triglyceride (TG),cholesterol(TC),low density lipoprotein -cholesterol (LDL -C)in the GDM group were signifi-cantly higher than the GIGT and NGT groups.However,high density lipoprotein -cholesterol (HDL -C)was signifi-cantly lower (F =69.29,98.15,70.32、141.43、61.92,106.06,157.06,90.59,25.25,all P <0.01).FIB was sig-nificantly positively correlated with BMI,FBG,FIN,HOMA -IR,TC,TG,LDL - C (r =0.441,0.682,0.506, 0.599,0.493,0.591,0.633,all P <0.01 ),and negatively correlated with HDL -C(r =-0.419,P <0.01 ).Multiple stepwise regression analysis indicated that BMI,LDL -C,FBG and TG were independent risk factors affect-ing FIB(t =7.683,2.678,3.184,3.844,all P <0.01);FIB,BMI,FBG,FIN and TC were independent risk factors influencing HOMA -IR(t =68.784,3.201,29.702,58.100,2.904,all P <0.01).Conclusion Pregnant women have IR and blood lipid disorders during the mid -trimester,the overexpression of FIB is closely related to it.

Objective:To evaluate the effects of periodontal treatment with scaling and root planning supplemented with chlorhexidine on plasma lipids in patients with chronic periodontitis and hyperlipidemia(CPH).Methods:6 1 patients with CPH were randomly as-signed into control-treatment group(n=30)and intensive-treatment group(n=31).Patients in the control-treatment group underwent a standard cycle of supragingival mechanical scaling and polishing.Patients in the intensive-treatment group underwent the adjunctive full-mouth intensive removal of subgingival dental plaque biofilms with the use of scaling and root planning.Periodontal parameters,to-tal cholesterol(TC),triglycerides(TRG),high-density lipoprotein(HDL)and low-density lipoprotein(LDL)were measured before treatment and 2 and 6 months after treatment.Results:2 and 6 months after treatment,TRG was significantly lower in the intensive-treatment group than that in the control-treatment group(P<0.05),the levels of HDL were significantly higher(P<0.05);however, the levels of total cholesterol and LDL,in the intensive-treatment group were not significantly different from those in the control-treat-ment group 2 and 6 months after therapy.Conclusion:Intensive periodontal treatment may improve serum lipid levels in patients with hyperlipidemia and chronic periodontitis.

The core protein (CP) of the classical swine fever virus (CSFV) is one of its structural proteins. Apart from forming the nucleocapsid to protect internal viral genomic RNA, this protein is involved in transcriptional regulation. Also, during viral infection, the CP is involved in interactions with many host proteins. In this review, we combine study of this protein with its disorders, structural/functional characteristics, as well as its interactions with the non-structural proteins NS3, NS5B and host proteins such as SUMO-1, UBC9, OS9 and IQGAP1. We also summarize the important part played by the CP in CSFV pathogenicity, virulence and replication of genomic RNA. We also provide guidelines for further studies in the CP of the CSFV.
