Objective To explore the relationship between primary hypothyroidism and hyperuricemia and to speculate their possible mechanism .Methods The levels of FT3 ,FT4 ,TSH, Anti-TG ,Anti-TPO, TRAb, UA, TC, TG, LDL-C, HDL-C,Hcy, Cys,β2 MG and 24hUA were measured in 36 patients with hypothyroidism , compared with 20 healthy sub-jects.According to the absence or presenceof Anti-TG, Anti-TPO and TRAb, the patients were divided into two sub-groups:the Hashimo to(HT) hypothyroidism group (27 cases) and the non-HT hypothyroidism group (9 cases)before they were compared with each other .Results Compared with healthy subjects , patients with hypothyroidism had higher TSH , TC,TG, LDL-C, UA, Hcy,Cys,andβ2MG,and lower FT3,FT4,HDL-C,and 24hUA.The difference was significant (P<0.05);the thyroid function, autoimmune antibodies, TC, LDL-C, UA and 24hUA were also significantly differen between the two sub-groups.Conclusion Patients with hypothyroidism are more prone to hyperuricemia , which may be related to decreased thyroid hormone , lipid metabolism disorder and hyperhomocysteine .The level of UA is higher in HT hypothyroidism than in non-HT hypothyroidism , indicating that autoimmune factors may be involved in the occurrence of hyperuricemia .

Phthalate esters (PAEs)are by far the most widely used plasticisers and are categorized as high and low,depending on their molecular weight.Because of their extensive use,humans are most likely exposed to PAEs in the workplace and home environment through direct as well as indirect sources.Injection,inhalation,intravenous injection and skin absorption are potential pathways of expo-sure.With respect to health effects,phthalates are often classified as endocrine disruptors because of their ability to interfere with the endocrine syste m in the body.Furthermore,PAEs possess reproductive toxicity because of their influence on development of the reproductive system in infancy and development and differentiation of germ cells in adults.PAEs promote pathogenesis and development of liver cancer by activating peroxisome proliferator-activated receptor (PPAR)and DNA methylation.In addition, PAEs,which inhibit the i mmune functions of macrophages and pro mote hypersensitive response,pos-sess immunotoxicity.PAEs are also carcinogens that promote pathogenesis and development of cancers including breast,ovarian and so me other cancers.

Objective To investigate the injury characteristics and prognostic risk factors of patients with craniocerebral injury so as to provide some suggestions for the improvement of medical prevention,intervention and treatment measures.Methods Trauma database system was applied to collect the medical records of 661 patients with traumatic brain injury admitted to the Department of Neurosurgery of 105th Hospital of Hefei in 2009.Their general conditions,injury characteristics and outcomes were analyzed and the risk factors affecting their outcomes were investigated by Logistic regression analysis.Results Of the patients with craniocerebral injury,the males accounted for 70％ (463/661).The patients at 45 years old or so had the highest incidence of craniocerebral injury.Patient number in the second half of one year was 1.65 times more than that in the first half of one year (412/249 ).Most patients were injured from traffic accidents (87.7％,580/661 ) and 512 patients (77.5％) suffered from multiple injuries.ISS,injury causes,age and injury incidence quarters showed close correlation with the final outcome.Conclusions The patients with craniocerebral injury demonstrates distinctive characteristics in aspects of gender,age,incidence time,injury causes,and multiple injuries,but the ultimate outcomes are related to the injury severity,injury causes,age and other factors.

Objective To study the test-retest reliability in quantitative measurement of proprioception using Tecnobody rehabilitation system.Methods Nine healthy volunteers [4 males,5 females,averaged age (22.8 ±0.68) years] participated in three consecutive measurements on both feet by using Tecnobody rehabilitation system for computerized proprioceptive assessment.Standard error of measurement(SEM),correlation coefficient and intraclass correlation coefficient(ICC) obtained from the three consecutive measurements were used to analyze the Timeused in each measuring session,and the average track error (ATE) of the measurements.ResultsSEM values of Time in left foot and right foot were 3.07 ～ 3.83 and 6.65 ～ 8.44 respectively.ATE values in left foot and right foot were 1.33 ～ 1.97 and 1.39 ～ 1.91 respectively.The Time and ATE correlation coefficients of left foot / right foot were 0.919/0.6 and 0.808/0.831,respectively.The Time ICC values were 0.893/0.639 for left foot / right foot,respectively ; and the ATE ICC values were 0.716/0.734 for left foot / right foot,respectively. Conclusion The Tecnobody rehabilitation system provided a fairly good reliability in both relative andabsolute values in quantitative evaluation of proprioception in the feet.These data in a larger amount may be useful for setting up variables and the standard values of the local population for reference in proprioceptive rehabilitation.

ObjectiveTo investigate the association of HLA-Cw and -DRB1 alleles with psoriasis vulgaris,and to provide a clue to the study into the etiology of psoriasis.MethodsVenous blood samples were obtained from 81 patients with psoriasis vulgaris collected during 2006-2011 at the Department of Dermatology,First Affiliated Hospital of Inner Mongolia Medical College,as well as 100 age- and gender-matched healthy controls.Both the patients and controls are unrelated Mongolia in Inner Mongolia.PCR with sequence-specific primers(PCR-SSP) technique was used to genotype the HLA-Cw and DRB1 loci.ResultsThe patients with psoriasis vulgaris showed a significantly higher frequency of HLA-Cw*06(0.438 vs.0.175,Pc ＜ 0.01) and DRB1*07(0.241 vs.0.110,Pc ＜ 0.012),but a lower frequency of HLA-Cw*04(0.031 vs.0.150,Pc ＜ 0.01 ) and DRB1*04 (0.093 vs.0.235,Pc ＜ 0.01 ) than the healthy controls did.Increased frequencies of HLA-Cw*06 and DRB1*07 alleles were observed in patients with an onset before 40 years of age and those without a family history,together with a decreased frequency of HLA-Cw*04 and DRB1*04 alleles,compared with the healthy controls(Pc ＜ 0.05).The frequency of HLA-Cw*06 allele was significantly higher in patients with a positive family history and patients with an onset of no younger than 40 years of age than in the healthy controls (both Pc ＜ 0.05).ConclusionsHLA-Cw*06 and -DRB1*07 alleles may be susceptibility determinants to psoriasis vulgaris,while HLA-Cw*04 and -DRB1*04 alleles may be protective factors against psoriasis vulgaris,in Mongolia from Inner Mongolia.HLA-DRB1*07 allele may be a susceptibility gene for psoriasis,while HLA-Cw*04 and -DRB1*04 alleles may be protective factors against psoriasis,in patients with an onset before 40 years of age.

Objective To observe the effect of vein anastomosis by microvascular anastomotic device in head and neck reconstruction.Methods Sixteen cases needing free flaps were randomly selected in head and neck cancer patients with locally advanced lesion.Their veins were anastomosed by microvascular anastomotic device.Other 40 cases whose veins were anastomosed by manual anastomosis were selected as control during the same year.The statistical data of the time of veins anastomosis,thrombosis and the rate of flaps salvage were compared.Results The average time of venous anastomosis was 6.31 ± 0.87 minutes,which was lower than the manual anastomosis (19.20 ±4.62 minutes) significantly.There was no thrombosis,which was not significant different with the manual anastomosis.One case's venous blood flow was not smooth for the angled vein and the flap salvage operation was successful.Conclusion The time of venous anastomosis is shorten significantly by microvascular anastomotic device.The incidence of thrombosis is the same compared with venous anastomoses performed with sutures.The microvascular anastomotic device system allowed a time-efficient and safe venous anastomosis.
