Objective To investigate the association of leptin receptor gene Gln223Arg polymorphism with metabolism syndrome and insulin resistance. Methods The genotypes of leptin receptor in 167 patients with metabolic syndrome and 216 healthy subjects were determined by polymerase chain reaction restriction fragment length polymorphism. The biochemical indicators were detected. Results The frequency of A alleles was significantly higher in patients with metabolic syndrome than in healthy subjects. The risk of metabolic syndrome in inviduals with allele A was 3. 302 folds of that with allele G( P<0.01 ). Compared with allele G, the patients withA allele had higher body mass index,blood pressure, blood glucose, insulin level, waist circumference, and more serious dyslipidemia. The risk of insulin resistance in patients with A allele was 3. 446 folds of that with allele G (P<0.01). Conclusions Leptin receptor gene Gln223Arg polymorphism is associated with an increased risk of metabolic syndrome and insulin resistance.

Objective To investigate the therapeutic effects of alendronate combined with Caltrate D on regional bone mineral density (BMD) in elderly type 2 diabetic women with osteoporosis. Methods Thirty-four elderly type 2 diabetic women with osteoporosis aged 60-79 years (average 68. 0±4.5 years), with body mass index (BMI) of (25.0±3.7) kg/cm2 and duration of diabetes (8.9 ±4.4) years were enrolled. At the basis of a comprehensive management, the patients were treated with alendronate combined with Caltrate D for 6 months. BMD of the lumbar spine and hip, several biochemical indexes were measured before and after treatment. Results After the 6 months treatment, the BMD of different regions at lumbar spine and hip all increased. The T value and BMD were significantly higher at lumbar spines than at hip (both P＜0.01). The differences of T value and BMD of different regions were significant (P = 0.003 and 0.005,respectively). BMD percent change at lumbar spine were L4 (44.7%) ＞ L3 (31.9%) ＞ L total (27.3 % ) ＞ L1 (20.0%) ＞ L2 (14.3 % ), and the BMD percent changes were significantly higher in L3 and L4 than in other regions at lumbar spine (P=0. 038 and 0. 008, respectively). The changes of T value and BMD were significantly higher in L3, L total, L1 and L4 than in L2 (T value: P=0. 036,0. 042, 0. 006 and 0. 004, respectively; BMD: P=0. 002, 0. 002, 0. 003 and 0. 001, respectively).Conclusions On the basis of comprehensive management, the 6 months treatment with alendronate combined with Caltrate D in elderly type 2 diabetic women with osteoporosis may achieve good therapeutic effect at lumbar spines, especially at the lower lumbar spines, while less effective at hip.

Objective: To compare the biotype and genetic similarity between groups of commensal and pathogenic strains of candida species. Methods:Random amplified polymorphic DNA (RAPD) was used to analyse the type of Candida albicans. Results: 12 pathogenic isolates of Candida albicans, 3 commensal isolates of Candida abicans and 3 isolates of pathogenic non-albicans were obtained. The similarity coefficient of albicans with non-albicans was 51.7% by RAPD. Intra-candida similarity coefficient was more than 70%. Both the commensal and pathogenic isolates showed the genetically similar to C. albicans. Intro-isolate DNA polymorphism was observed by RAPD. Conclusion: Both the commensal and pathogenic groups contain a major cluster of genetically similar C. albicans isolates.

Objective To explore the clinical significance of preserving the intercostobrachial nerve (ICBN) in the radical resection of breast cancer. Method All of 140 cases of breast cancer with Ⅰ - Ⅲ a stage operable eligible,were randomly divided into the experimental group with 79 cases (7 cases were rejected, 1 case was lost) that patients received radical resection of breast cancer with preservation of ICBN,and the control group with 61 cases (2 cases were lost) that patients received routine radical resection of breast cancer based on the time of admission. Analyzed postoperative local recurrence and compared to sensory dysfunction of the two groups. Results There was no significant difference between the two groups of patients in the rate of postoperative local recurrence [0-4.2% ( 3/71 ) vs. 0-3.4% (2/59)] ( P ＞ 0.05 ). The local sensory disturbance of the experimental group [2.8% (2/71 )-11.3% (8/71)] was significantly lower than the control group [54.2%(32/59)-71.2%(42/59)], there was significant difference between the two groups (P ＜ 0.01 ). Conclusion Radical resection of breast cancer with preservation of ICBN is an ideal operation in breast cancer.

Objective: To explore the relationship between 1eptin receptor gene Gln223Arg polymorphism and metabolism syndrome (MS) with its impact on cardiac structure and function.
Methods: Our research included 2 groups:MS group, n=167 patients with ifrst diagnosed MS without treatment in our hospital from 2005-10 to 2008-6 and Control group, n=216 healthy subjects from regular physical examination. Blood pressure, biochemical features, insulin levels and echocardiography were detected;leptin receptor Gln223Arg genotypes were measured by PCR-RFLP;the above indexes were compared between 2 groups.

Objective To investigate ATM deletion [del (ATM)] in chronic lymphocytic leukemia (CLL) and study its correlation with the clinical stage. Methods Spectrum Orange~(TM) labeled sequence specific DNA probe for ATM locus on 11q22.3 and fluorescence in Situ hybridization (FISH) was used to examine del (ATM) in 28 newly diagnose patients with CLL. FISH analysis were performed on bone marrow smears. Clinical staging was done according to Binet Method.Fisher exact propability was used to study the relations between del (ATM) and clinical feature. Results 4 out of the 28 cases were found with deletion of ATM. The incidence of del (ATM) in BinetA, BinetB and BinetC was 1/9 (11.1 %), 1/8 (12.5 %), 2/11 (18.2 %), respectively. Fisher exact propability showed that deletion of ATM was not associated with its clinical feature. Conclusion Application of FISH on archival bone marrow smears is a simple, liable method, and can be readly used to retrospective study of clonal blood system diseases. Deletion of ATM was common cytogenetic changes in CLL patients.And the significance of del (ATM) in the prognosis of CLL in China needs to be further investigated.

Objective To analyse the fusion genes derived from chromosome structural aberrations in acute myeloid leukemia(AML) and the relationship between fusion genes and the MICM classification, clinical diagnosis, chemotherapy and prognosis. Methods The expression of fusion gene in bone marrow samples was detected with multiplex RT-PCR technique and chromosome karyotypes, immunological phenotypes and clinical data were analyzed in 60 acute myeloid leukemia newly diagnosed. Results 37 cases(61.67 %) of 60 patients carried 5 kinds of fusion genes consisting of MLL-AF9, TLS-ERG, CBFβ-MYH1, AML1-ETO and PML-RARα. The activation of oncogene HOX11 was detected in 13 AML cases, three of them with other chromosome aberration simultaneously.23 cases of 31 patients carrying AML1-ETO or PML-RARα, reached complete remission(CR) after chemotherapy and without relapse. Conclusion Gene typing is the most precise classification method that can direct clinical treatment and evaluate prognosis. Multiplex RT-PCR technique, which can quickly screen 29 kinds of fusion gene derived from chromosome structural aberrations at one time, maybe helpful to improve M1CM classification and guide the choice of treatment.

Objective To explore the deletion of chromosome 13 in multiple myeloma (MM), clinical significance of FISH-defined partial deletion chromosome 13 in MM patients were investigate. Methods Fluorescence in situ hybridization (FISH ) was performed on bone marrow from 38 patients with MM to study the deletion of Rb-1 gene and locus 13q14 on chromosome 13. Fisher exact propability was used to study the relations between partial deletion of chromosome 13 and clinical features. Results 20 out of the 38 cases were found with deletion of chromosome 13; deletion of Rb-1 gene in 4 cases; deletion of locus 13q14 in 2 out of 38 cases; and 14 cases with both of deletions. Fisher exact propability showed that deletion of chromosome 13 was associated with hypso-serum lactic dehydrogenase, stage of ISS. Conclusion Deletion of Rb-1 gene and locus 13q14 were both common cytogenetic changes in MM patients with effect on the biological behavior of the disease, but the value of del (13q14) in MM needs further investigation. FISH was a rapid, accurate and sensitive technique in the analysis of del (13q14) in MM.
