Objective To investigate the status of diabetes and its risk factors in Karamay.Methods A sampling survey was carried out in Baijiantan district of Karamay from March,2003 to Dec.,2003,all subjects aged 20 to 75 and lived 5 years and above were selected with stratified sampling method according to the age structure of the inhabitants in Karamay.Results Diabetes prevalence was positively correlated with age(OR=1.047),male(OR=1.922),obesity(OR=1.641),hypertension(OR=1.624) and hyperlipidemia(OR=2.131)(P

Objective To explore the causes,clinical feature,diagnoses and prognosis of children with acquired immunodeficiency syndrome (AIDS) and improve our awareness of this disease.Methods The clinical and laboratory data of 12 children with AIDS were analyszed retrospectively and the clinical feature was summed up.Results Among 12 children with AIDS,9 cases were boys and 3 cases were girls,aged from 45 days to 9 years old.The parents of 11 cases were positive in serological human immunodeficiency virus (HIV) antibody or died of AIDS.The main manifestations were developmental delay and various degree cacotrophia(12 case,100%),the others included abnormity fever,discontinuity cough and hepatosplenomegaly(10 cases,83.3%),recurrent diarrhea and lymphadenopathy (8 cases,66.7%),skin lesion(6 cases,50%),cerebral hypoplasia (4 cases,33.6%),oral candidiasis(3 cases,26.7%),and tympanitis(2 cases,16.7%).Laboratory tests showed:all of 12 cases were positive in serological HIV antibody by test for 2 times.The percent of CD4+ and the ratio of CD4+ to CD8+ were decreasing.One case was dead and the others had bad effect with allopathy.Conclusions Children with AIDS have short clinical latency,diversified clinical manifestation,low cell-mediated immunity function and bad effect with allopathy.To improve our awareness of the di-sease should be helpful for diagnosing and treating it early and prolonging the patients' life.

A 19-year-old Chinese woman presented with progressive ulcers and recurrent fever for 1 year.The lesions originally began with purplish red maculopapules,then rapidly developed into ulcer with severe pain and spread to the trunk and extremities accompanied by intermittent fever.Histopathology revealed lymphoid infiltration of middle and large atypical T cells throughout the dermis and subcutaneous fat laver along with focal epidermotropism.The lymphoid infiltrates were positive for CD3,CD8,T-cell intercellular antigen(TLA)and T-cell receptor β(TCR-β).Gene analysis showed the rearrangement of T-cell receptor gene.According to the above findings,the patient was diagnosed as primary cutaneous aggressive epidermotropic CD8-positive cytotoxic T-cell lymphoma. Combined thempy with cyclophosphamide,vincristine,prednisone and bleomycin resulted in partial remission of skin lesions,but she eventually died 22 months after the onset of disease.

Objective To examine aortic dissection by using T1W/TFE sequence and to observe the imaging characteristics of aortic dissection in T1W/TFE sequence. Methods Twenty patients confirmed as aortic dissection by CT and ultrasound received MRI scanning of T1W/TFE sequence on inclined sagittal and SE sequence on transaxial at Philips Gyroscan 1.5 MR imager. The signal changes of aortic dissection in T1W/TFE sequence were observed. Results In T1W/TFE sequence, we observed not only an intimal flap, a double lumen and range of aortic dissection, but also the site of intimal tear and thrombus in the false lumen. Conclusion By using T1W/TFE sequence we obtained the high quality image of aortic dissection and high contrast of imaging. Combined with SE sequence , T1W/TFE sequence can provide reliable information for analyzing and curing aortic dissection in clinic.

Purpose:To investigate the relationship between cell apoptosis and dephosphorylated RB protein in human breast cancer. Methods:In our work,human breast cell lines (MCF-7/S,the chemosensitive cell line and MCF-7/ADR,the chemoresistent cell line)were evaluated. Chemosensitivity of two cell lines was evaluated by the MTT colorimetric assay;the expressive levels of dephosphorylated RB protein were detected with immunocytochemistry. Apoptosis rates were determined by flow cytometry(FCM). Results:ADR inhibited proliferation of chemosensitive cell line MCF-7/S ,the 50% inhibition concentration (IC 50 ) was 0.128 ?g/ml;And IC 50 of MCF-7/ADR was 10.89 ?g/ml. The chemotherapeutic sensitivity of MCF-7/S was more than that of MCF-7/ADR by 86 times . Before treatment with ADR,phosphorylated RB protein was positive in two cell lines,but dephosphorylated RB protein was negative;After treatment of different concentration ADR,when the concentration of ADR was increased,expression of dephosphorylated RB protein elevated accordingly in MCF-7/S,but no significant change in MCF-7/ADR. Apoptosis and cell cycle was detected by FCM assays shows ADR induced apoptosis of MCF-7/S more than MCF-7/ADR(P0.05).

Objective To investigate the correlations between plasma levels of carnitine(CT),free fat acid(FFA) and insulin resisitance in children with simple obesity.Methods Fifty-six children diagnosed with simple obesity were enrolled as study group(obesity group),36 healthy children as control group.The concentration of plasma level of insulin was measured by radioimmunoassay(RIA),CT was measured by high performance liquid chromatography(HPLC),FFA and triglyceride(TG) were measured by enzymatic-colorimetric assay.Body mass index(BMI) and waist to hip ratio(WHR) were caculated.Insulin sensitivity index (InSI) and insulin resistance index (InRI) were cacula-ted by homeostasis model assessment of insulin resistance (HOMA-IR).SPSS 13.0 software was used to analyze the data.Results The concentration of CT in plasma was (43.67?12.75) ?mol/L in obesity group,(58.31?21.25) ?mol/L in control group,respectively.There was a significant difference between 2 groups (t=2.566 P

OBJECTIVETo explore the expression of Ghrelin and high mobility group protein B1 (HMGB1) in the serum and the intestinal tissue of sepsis model rats, and to evaluate the effect of electro-acupuncture (EA) at Zusanli (ST36) on the expression of HMGB1 and Ghrelin.

METHODSForty-eight male Wistar rats were randomly divided into four groups, i.e., the sham-operation (sham), the cecal ligation and puncture group (CLP), the CLP + EA at Zusanli (ST36) group (EA), and the CLP + Ghrelin receptor blocking agent + EA group (GHSRA), 12 in each group. A sepsis rat model was prepared by CLP. The incision of the abdominal wall was immediately sutured along the ventral midline for rats in the Sham group. In the EA group EA at Zusanli (ST36) was performed 20 min after CLP surgery with the constant voltage (2 - 100 Hz, 2 mA) for 30 min. In the GHSRA group, Ghrelin receptor blocking agent, [D-Arg1, D-Phe5, D-Trp79, Leu11]-substance P (700 nmol/kg), was administered through intravenous injection immediately after CLP, and 20 min later, EA at Zusanli (ST36) was performed in the same way as for rats in the EA group. Blood samples were withdrawn 12 h after CLP. The serum levels of Ghrelin and HMGB1 were detected using ELISA. Ghrelin expressions and the number of Ghrelin immunopositive cell in the jejunum were determined by immunohistochemistry. HMGB1 contents of the jejunum tissue were detected by Western blotting.

RESULTSCompared with the Sham group, the number of serum immunopositive cells and the expression of HMGB1 in the jejunum tissue significantly increased and levels of Ghrelin and the expression rate of immunopositive cells significantly decreased in the CLP group (P < 0.05). Compared with the CLP group, the number of serum immunopositive cells and the expression of HMGB1 in the jejunum tissue significantly decreased, but levels of Ghrelin and the expression rate of immunopositive cells significantly increased in the EA group (P < 0.05). Compared with the EA group, the number of serum immunopositive cells and the expression of HMGB1 in the jejunum tissue significantly increased in the GHSRA group (P < 0.05), but there was no statistical difference in levels of Ghrelin between the two groups (P > 0.05). The serum level of HMGB1 was negatively correlated with Ghrelin in the Sham group, the CLP group, and the EA group (r = -0. 528, P < 0.01).

CONCLUSIONSEA at Zusanli (ST36) could inhibit the expression of HMGB1 in the jejunum of septic rats, and promote the expression of Ghrelin. The expression of HMGB1 was inhibited by Ghrelin receptor blocking agent, which suggested that the anti-inflammation of EA at Zusanli (ST36) might be associated with Ghrelin.
