ABSTRACT

Objective To investigate and establish thyroid function reference range during 3 pregnant stages in Chaoshan area:thyrotropin (TSH),free thyroxin (FT4).Methods 863 healthy pregnant women visited antenatal clinic in the Second Affiliated Hospital were included in this study.By detecting serum levels of TSH,FT4,thyroglobulin antibody (TgAb),and thyroid peroxi-dase antibody (TPOAb)in these women,the euthyroid reference ranges of serum TSH and FT4 in different pregnant stages were established based on the standards of the United States National Institute of Clinical Biochemical (NACB)guidelines.Results The ranges of serum TSH in the first,second and third trimester of pregnancy were 0.13-3.93 mIU/L,0.14-4.55mlU/L,and 0.42-3.85 mIU/L,respectively.The ranges of serum FT4 levels in these 3 stages were 12.00-23.34 pmol/L,6.27-12.65pmol/ L, and 9.80-18.20 pmol/L,respectively.The range of serum TSH levels in our study were similar with the reference range recom-mended by the guidelines in China,but were different compared with the American Thyroid Association (ATA)guidelines.Conclu-sion TSH,FT4 levels show dynamic changes during different stages of pregnancy.The thyroid function ranges of healthy pregnant women in Chaoshan area are quite different compared with non-pregnant population and pregnant women in distinct area.Due to the differences of diet,iodine intake,economy and culture in Chaoshan area,regional thyroid function reference ranges specific for differ-ent stages of pregnant women should be established.

ABSTRACT

Objective To ascertain the significance of qualitative and quantitative detections of urine neutrophil gelatinase-associ-ated lipocalin(NGAL)in the early diagnosis of diabetic nephropathy.Methods 74 patients with diabetes mellitus were divided into the normoalbuminuria group[(DN1 ,n =26,urinary albumin excretion rate(UAER)300 mg/24 h)according to the 24 h UAER,and at the same time the control group(n=25)was set up.Both the activity and levels of urine NGAL in the above groups were examined and compared.Results The activity band of urine NGAL in each group were more distinct than that of the control group(P =0.000).The NGAL activity in the macroalbuminuria group was higher than that in the normoalbuminuria group(P 0.05);the quantitative detection demonstrated that differences of the NGAL content existing between the macroalbuminuria group and the other three groups had statistical significance(P =0.000),the urinary NGAL excretion in the macroalbuminuria group was higher than that in the microalbuminuria group,normoalbuminuria group and the control group(P =0.000);No differences were found between the control group and the normoalbuminuria group and between the control group and the microalbuminuria group(P >0.05).Conclu-sion For the patients with diabetic nephropathy,the activity detection of urine NGAL is more sensitive than UAER and the NGAL quantitative detection and could become a new type index in the early diagnosis of diabetic nephropathy.

ABSTRACT

The immunohistochemical staining showed the connexin 43 (Cx43) was strongly expressed (average gray value, AGV=230±5), distributed at junction area and intercalated disks of cardiocytes in normal rats,and much less expressed (AGV 193±4) (P<0.01) and distribution-disorganized in STZ-induced diabetic rats. This may be associated with the pathogenesis of diabetic myocardial lesions.

ABSTRACT

BACKGROUND: Diabetic cardiomyopathy is closely related to the high incident rate of diabetic heart failure. It is extremely significant to set up the successful dietetic cardiomyopathy model for the study on improving cardiac function.OBJECTIVE: To understand the influence of high blood sugar on myocardium by setting up the model of type 2 diabetes and diabetic cardiomyopathy.DESIGN: Completely randomized design, randomized and controlled study,in which, the experimental animals were taken as the objects.SETTING: Department of endocrinology of a university.METHODS: In the experiment, 99 newly born Wistar male rats were employed, randomized into experiment group (75 rats) and the control group(24 rats). In the control group, abdominal injection was done with sodium citrate buffer and the single abdominal injection was done with strptozocin(STZ)90 mg/kg in the experiment group. Ten weeks later, the glucose tolerance was assayed to determine the set-up of diabetes model. The ultrastructure of myocardium of rats was tested under electronic microscope after being sacrificed.MAIN OUTCOME MEASURES: To observer whether the myofibrillae and mitochondria of myocardiocytes alter or not in diabetic rats.RESULTS: In the experiment group, the fasting blood sugar[(8.87± 0.76)mmol/L] was slightly higher than that[ (5.88 ± 0. 45)mmol/L] in the control group, the blood sugar 2 hours after meal was remarkably higher than that in the control group and the glucose tolerance was abnormal. Under the electronic microscope, the myofibrillae presented focal degeneration and disarranged order of myofilament; mitochondria of myocardiocytes presented swelling and focal proliferation.CONCLUSION: This model is the satisfactory carrier for the study on diabetes Ⅱ and its myocardiopathy, which lays an experimental foundation for the study on cardiac function of type 2 diabetes.

ABSTRACT

Objective To explore the relationship among the blood glucose level and cerebral infarction(CI) size, neurological deficits, clinical outcome, complications and mortality in diabetic patients with cerebral infarction. Methods 60 cases of diabetes complicated with cerebral infarction and 60 normoglycemic patients with cerebral infarction were enrolled in this study, and the clinical data were compared between the two groups of patients. Results Compared with normoglycemic patients with cerebral infarction, diabetic patients with cerebral infarction had larger infarct size,more neurological deficits, worse clinical outcome,more complications and higher mortality because cerebral infarction occurred in the main branch. Infarction size was positively related with blood glucose level. Conclusion Hyperglycemia aggravated cerebral infarction and brain damage.Proper insulin administration to control blood glucose level was beneficial to the treatment and prognosis of cerebral infarction.

ABSTRACT

Apoptosis, also known as programmed cell death,is a normal process contributing to tissue tumor during development and in the adult.During development apoptosis is involved in tissue homeostasis and eliminating nonfunctional,superfluous or harmful cells.It is an active process controlled by some gene and factors such as caspases, bcl-2, Fas/FasL and NO.Type 1 diabetes mellitus is regarded as a chronic autoimmune disease resulting from progressive destruction of insulin-producing ?-cells in the pancreas.The relationship between apoptosis with its modulation and type 1 diabetes mellitus was reviwed.

ABSTRACT

AIM: To investigate the expression and function of apoptosis-related protein, Fas, FasL, and Bcl-2 in the pathogenesis of autoimmune thyroiditis. METHODS: Immunohistochemical staining was performed on 20 Hashimoto's thyroiditis (HT), 20 Graves' disease (GD), and 20 thyroid follicular adenoma (TFA, as control). RESULTS: All the cases expressed Fas, mainly on the cell surface and cytoplasm. FasL was found in all except 3 of the TFA. Bcl-2 in 15 of HT, 19 of GD, 17 of TFA. In TFA follicular cells expressed moderate Fas and minimal or absent FasL. In HT, follicles adjacent to infiltrating lymphocytes showed a increased levels of Fas and FasL, but infiltrating lymphocytes exhibited weaker staining of Fas and FasL than thyrocytes. In GD, thyrocytes and lymphocytes showed nearly similar Fas with HT, but rather weaker for FasL than HT. Bcl-2 was nearly similar in GD and TFA, but follicular cells in vicinity of lymphocytes and lymphocytes located in germinal centers of HT tissues exhibited significantly weaker. CONCLUSION: The expression of Fas, FasL and Bcl-2 in Hashimoto's thyroiditis and Graves' disease was nearly similar. Strong FasL expression and weak Bcl-2 expression on the follicles in HT may induce apoptosis. These results provide further proof that the functions of Fas and its ligand and Bcl-2 may play an important part in the pathogenesis of autoimmune thyroid diseases. The lymphocytes do not seem to be directly engaged in the process with their own FasL, but they may provide some cytokines that, in turn, up-regulates Fas and/or FasL leading to apoptosis.
