The advances in the diagnostic procedures for malignant thyroid tumors and the managements by surgery, ~(131)I therapy, radiation, chemotherapy and thyroid hormone suppression in recent years are reviewed and discussed.

Object: To investigate effect of different Laboratory conditions to examination of some hemostasis: prothrombin time(PT),activated partial thromboplastin time(APTT),fibrinogen(FIB) and thrombin time(TT).Methods: After treated with different method by appropriate reagent,specimens were measured for hemostasis by Sysmex CA7000 automatic machine.In method one blood was collected by general anticoagulative glass tube without silicification..In method two blood was collected by specific anticoagulative silicification glass tube provided by different manufactory.The measured result were compared by statistics method.Results: There was significant difference between method one and two when measured value of PT,APTT and TT were concerned(P

Objective:To study the clinical value of serum enzymatic activity in the diagnosis of hepatic carcinoma. Methods: The activity of serum ALP?GGT?AFU and 5'-NT was detected in 40 patients with primary hepatic carcinoma,30 patients with secondary liver cancer,40 patients with other kinds of hepatic disease and 40 normal persons. The all results were statistically analyzed. Results:The activity of serum ALP?GGT?AFU and 5'-NT in patients with primary or secondary liver cancer was significantly higher than that of other kinds of hepatic disease and normal persons(P

Changes of TSI level in 30 cases of Graves' disease undergoing long-term antithyroid drug treatment were studied with 22 normals as control. The patients were divided into 3 groups. The serum TSI activities were 282? 230% and 113?112% in group A (including 15 symptomatic cases following the treatment for 0-2 months) and group B (including 10 cases in remission and 7 cases from group A following the treatment for 12-26 months) respectively. The TSI level in group A was significantly higher than that in group B (P

Obiective To detect the carotid-femoral pulse wave veloeity(CF-PWV) and evaluate relation in pulse pressure (PP) and pulse wave velocity ('PWV), and prove the effect of dynamic error analysis system on pulse wave velocity measure. Methods 486 cases with essential hypertension were detected with carotid-femoral pulse wave velocity. The dynamic error was controlled in three kinds of condition: 15%>error>10%, 10%>error>5% and 5%>error, which PWV values were tested repeatedly with the effect of different errors observed. At the same time the blood pressure was measured and the pulse pressure was calculated. Results The pulse wave velocity which pulse pressure ≥60mm Hg (1mm Hg=0.133 kPa) was significantly higher than pulse pressure <60turn Hg [(14.2± 2.34)m/s and (8.5±1.81)m/s, P<0.001] . Pulse wave velocity and pulse pressure and age showed a significant positive correlation (pulse pressure r=0.529, P=0.000; age r= 0.331 P=0.003).When dynamic error is more than 10% and less than 15%, the diversity of PWV values showed the significance of statistics. Conclusion The effect of dynamic error analysis system on pulse wave velocity measure, less error test pattern is advantageous to enhance accuracy. The pulse pressure is closely related to pulse wave velocity. Arterial pulse wave velocity is a new evaluation of the indicators of arterial stiffness, and it's more scientific, accurate and eonvenient.

The epidemic characteristics of differentiated thyroid cancer(DTC)are changing, thyrotropin(TSH)suppressive therapy is also improving in recent years. The risks of recurrence and the death of patients, as well as the adverse effects of levothyroxine sodium treatment should be fully considered during thyroid hormone administration for patients of DTC. Hence, the degree of TSH suppression should be individualized in patients with DTC.

Objective To monitor intra-abdominal pressure (IAP) in critically ill patients.Methods A prospective cohort study was conducted.IAP was measured through the bladder technique.Patients were screened for intra-abdominal hypertension (IAH,IAP ≥ 12 mmHg,1 mmHg=0.133 kPa) upon ICU admission.The patients with IAH/abdominal compartment syndrome (ACS) were given appropriate treatment and management for IAH and/or ACS.Mean arterial pressure (MAP),IAP,abdominal perfusion pressure (APP),filtration gradient (FG) and serum creatinine (Cr) were determined in patients with or without IAH,as well as in survivors and non-survivors.Results The entire protocol of IAP measurement was completed in 88 patients.Number of IAH and ACS patients was 25 (28.4％) and 2 (2.3％),respectively.The number of survivors was 80 (90.9％),with 8 (9.1％) non-survivors.Compared with non-IAH patients,IAP and SCr were increased in IAH patients [IAP (mmHg):14.16 ± 2.43 vs.8.13 ± 2.28,t=10.984,P=0.000; SCr (μmol/L):126.72 ± 83.02 vs.73.41 ± 37.59,t=3.087,P=0.005],with a lower FG (mmHg:59.32 ± 17.08 vs.70.24 ± 15.03,t=-2.956,P=0.004).There were no significant differences in MAP and APP between IAH group and non-IAH group [MAP (mmHg):79.18 ± 12.33 vs.88.71 ± 17.34,t=-1.368,P=0.190; APP (mmHg):73.40 ± 16.11 vs.78.37 ± 14.32,t=-1.415,P=0.161].Compared with survivors,non-survivors showed significantly lower APP and FG [APP (mmHg):60.88 ± 14.58 vs.78.56 ± 14.06,t=3.382,P=0.001 ; FG (mmHg):50.38 ± 16.18 vs.68.81 ± 15.44,t=3.208,P=0.002],and higher SCr (μmol/L:129.12 ±83.62 vs.84.36 ± 55.15,t=-2.082,P=0.040).There was no significant difference in IAP and MAP between survivors and non-survivors [MAP (mmHg):71.00 ± 25.46 vs.84.38 ± 13.53,t =1.224,P=0.238 ; IAP (mmHg):10.62 ±5.34 vs.9.76 ± 3.40,t=-0.647,P=0.519].Conclusions Earlier IAP measurements in critically ill patients are essential for the detection of IAH/ACS and renal injury.With appropriate management of IAH/ACS,significant decrease in morbidity and mortality of patients has been achieved.

Objective To investigate relationship of serum insulin like growth factors(IGFs) and catch up growth. Methods The model of rats intrauterine growth retardation (IUGR) was built by clamping bilateral uterine arteries and veins of pregnant rats. The growth parameters (body weight and length), organs weights (brain, lungs and liver) and serum concentrations of IGF Ⅰ, Ⅱ of all neonatal rats was measured at birth and postnatal day 3 and day 5, respectively. Results (1)At birth, the serum levels of IGF Ⅰ, Ⅱ and the average growth parameters, organs weights in IUGR rats were significantly lower than those in control group( P 0.05). The serum of IGF Ⅱ in high catch up group was significantly higher than that at birth( P 0.05). Conclusion Both IGF Ⅰ, Ⅱmay play an important role in the regulation of catch up growth and the decrease of IGF Ⅰ, Ⅱlevels may be the internal factors contributing to the absence of postnatal catch up growth in IUGR rats.

T),resulting in His to Leu(CAT→CTT) substituted at codon 435(H435L).No mutation was identified in the patient's parents.HT occurred in the patient during following-up.Conclusion H435L mutation in exon 10 of TR? gene leads to resistance to thyroid hormone.Meanwhile,consistent RTH might lead to HT.
