Objective:To investigate the correlation between the microsatellite polymorphisms in ob gene 3′flanking region with obesity in Chinese Han ethnicity in Shanghai.Methods: The genotypes of polymorphisms in ob gene 3′flanking region were determined by PCR in 232 Chinese Han subjects(including 130 obese patients and 102 normal controls).The clinical data,including height,weight,waist circumference,hip circumference,body mass index,waist-to hip ratio(WHR),blood glucose,serum insulin,blood lipids,and uric acid,were compared between the 2 groups.Results: No significant difference of genotype frequency(Ⅰ/Ⅰ 0.115,Ⅰ/Ⅱ 0.331,Ⅱ/Ⅱ 0.554 vs Ⅰ/Ⅰ 0.059,Ⅰ/Ⅱ 0.333,Ⅱ/Ⅱ 0.608) and allele frequency(Ⅰ 0.281,Ⅱ 0.719 vs Ⅰ 0.225,Ⅱ 0.775) of ob gene 3′flanking region was observed between the 2 groups.In obese group,patients with Ⅰ+Ⅱ genotype was associated with increased WHR compared with those with Ⅱ/Ⅱ genotype(0.91?0.05 vs 0.86?0.03,P=0.047).Logistic regression analysis showed that WHR was independently correlated with ob gene polymorphisms(P=0.042).Conclusion: Polymorphisms in ob gene 3′ flanking region are correlated with central obesity in obese patients of Chinese Han ethnicity in Shanghai.

0.05). Conclusion: The IQ of children with epilepsy is lower than that of normal children .The epilepsy could impact the intelligence of children.

Statin therapy has been shown to play a fundamental role in the treatment of coronary heart disease.Some studies have identified associations between genetic variants and response or toxicity in statin treatment.This review summarizes current knowledge of the pharmacogenomics of statin therapy in order to help to select the best individually adapted statin treatment for patients.

Objective To explore the biological features of hematopoiesis reconstitution by using genetic marking.Methods NeoR gene was transduced into bone marrow(BM)cells of mouse mediated by liposome.Then these cells were transplanted into lethally irradiated recipients.The hematopoiesis reconstitution was observed and the marker gene in spleen and BM cells of recipients after hematopoiesis reconstitution was examined.Results The transplanted recipients remained alive and healthy.But the irradiated mice with no transplantation died from BM aplasia soon.Meanwhile,the cells from spleen and BM of transplanted mice could be alive in G418 system,and contained the DNA fragments of NeoR gene by PCR.Conclusion Gene-modified BM cells could be used to reconstitute hematopoiesis successfully and express the foreign gene to some extent stably.

Objective To investigate the association of Lys656Asn polymorphism in leptin receptor gene with serum triglyceride level.Methods The genotypes of Lys656Asn polymorphism in LepR gene were maped by polymerase chain reaction-single strand conformation polymorphism(PCR-SSCP) assay in 232 unrelated subjects of Shanghai Chinese population.The clinical data were also analyzed.Results No significant difference of genotype frequency of Lys656Asn polymorphism in LepR gene was observed between obese and non-obese groups.In obese group,"G" Allele was associated with increased triglyceride level(1.74?0.91 vs 0.95?0.32)(P

Objective To explore the changes of appendicular skeletal muscle (ASM) in peritoneal dialysis (PD) patients, and to analyze the relationship between ASM changes and dietary intake.Methods One hundred and fourteen PD patients were enrolled in Department of Nephrology, Peking University Third Hospital using convenience sampling.At baseline, and 6 and 12 months after PD, bioelectrical impedance analysis was used to assess the body weight, total muscle mass, and ASM of these patients, and three-day food record was used to assess the dietary intake.Demographics and clinical data were also collected at baseline.Results Compared with baseline, the patients' ASM at 12 months after PD decreased significantly [(19.27 ± 5.59) kg vs.(25.65 ±6.09) kg, P =0.000], the dietary protein intake and energy intake decreased significantly [(0.85 ± 0.21) g/(kg · d) vs.(0.90 ± 0.27) g/(kg · d), P =0.038;(128.37 ± 26.67) kJ/(kg· d)vs.(137.27 ±29.23) kJ/(kg· d), P=0.001].The patients were divided into three groups based on ASM loss, the mean dietary protein intake of the top-loss 1/3 group was statistically lower than that of the bottom-loss 1/3 group [(0.82 ± 0.18) g/(kg · d) vs.(0.91 ± 0.20) g/(kg · d), P =0.021].Conclusions With the continuation of PD, ASM of patients may decrease, which is likely to be mainly related to deficiency in protein and energy intakes.Dietary management should be strengthened in PD patients to alleviate the loss of ASM.

Objective To investigate the effects of rubella virus R16 infection on heat shock protein 70 (HSP70) and heat shock transcription factor 4 (HSF4) in the human embryonic lens epithelial cells in vitro. Methods The human embryonic lens epithelial cells were infected by rubella virus R16 for 3, 7 and 14 days respectively in vitro. Then the mRNA levels of HSP70 and HSF4 were measured by Real-time PCR assays, the HSP70 protein level was detected by Western blot assay, and the DNA sequence of HSF4 was also identified by DNA Sequencing. Results Both mRNA and protein levels of HSP70 were increased dramatically at 3 and 7 days after rubella virus R16 infection in vitro. But mRNA levels of HSF4 were decreased significantly. The DNA sequence of HSF4 had no change in the human embryonic lens epithelial cells at 14 d after rubella virus R16 infection. Conclusions Rubella virus R16 could directly induce the increased expression of HSP70 in the human embryonic lens epithelial cells infected by rubella virus R16 in vitro, which may prevent human embryonic lens epithelial cells from infecting with virus. The heat shock transcription factor may serve as a negative regulator at transcription level. However, the DNA sequence of HSF4 had no change in the human embryonic lens epithelial cells within 14 days after rubella virus R16 infection.

The identification traumatic cataract must be based on the optical dysopia after ocular injuries. 72 cases of traumatic cataract were classified into 3 groups according to the classification of WHO about optical dysopia. There were 9 cases low vision, 58 cases blind and 5 incorporated cases after injuries. After operation, there were 12 cases that stenopeic spectacles vision was 0.4～1.2, 29 cases were low vision, 26 cases blind. The results suggested that the vision of traumatic cataract could be changed after operation, and the best time for forensic identification could be 1 or 2 months after operation.

Objective To study the effect of the polymorphism of (AC) n of aldose reductase (AR) gene on the erythrocyte AR activity in type 2 diabetes mellitus (DM). Methods One hundred and sixty three cases of type 2 DM and forty two controls were included in this study. The subjects were devided into DM without diabetic microangiopathy (DMAP) (NDC) (66 cases), DMAP groups (97 cases), and normal controls (CON) (42 cases); further, according to the type of allele, the subjects were devided into DM with Z+2 (DZ+2) (54 cases), DM with Z-2 (DZ-2) (35 cases), DM with both Z+2 and Z-2 (Z+2/Z-2) (18 cases), DM with neither Z+2 nor Z-2 (X/X) (56 cases), non DM with Z+2 (NZ+2) group (21 cases) and non DM with Z-2 (NZ-2) groups (7 cases). AR activity (ARA) was measured by modified Sriratava method. The differences of ARA were compared among these groups. Results ARA in DMAP group was significantly higher than that in NDC group, ARA in NDC group was significantly higher than that in CON group. Among DZ-2, DZ+2, Z+2/Z-2 and X/X groups, ARA was the highest in DZ-2 group and the lowest in DZ+2 group. ARAs in DZ-2 and NZ-2 groups were significantly higher than those in DZ+2 and NZ+2 groups respectively. In DZ-2 and DZ+2 groups ARA was significantly higher than that in NZ-2 and NZ+2 groups respectively. Conclusion The activation of AR plays an important role in the development of DMAP. Z-2 allele may be an activator and Z+2 allele may be an inhititor of AR.
