Objective To investigate the probable risk factors for type 2 diabetic patients complicated nonalcoholic fatty liver disease (NFLD)in elderly, through comparing the body composition, serum lipid profile, incidences of abdominal obesity and metabolic syndrome (MS) between elderly type 2 diabetic patients with and without NFLD. Methods The enrolled elderly type 2 diabetic patients were divided into NFLD group (n=83) and non-NFLD group (n=85). Their clinical data including body composition, serum lipid profile, incidences of abdominal obesity and MS were analyzed retrospectively and compared. Results Compared with non-NFLD group, the BMI [(26.9±2.5) kg/m~2 vs. (24.1±2.5) kg/m~2, P=0.000], waist-hip ratios (WHR) ((0.92±0.07) vs. (0.87±0.06), P=0.000], total body fat percentage [(29.6%±6.6%) vs. (25.3%±5.5%),P=0.000], abdominal fat [(11.0±2.5) kg vs. (8.7±2.3) kg, P=0.000], visceral fat [(3.0±0.7) kg vs. (2.3±0.6)kg, P=0.000], visceral fat area [(97.6±22.2) cm~2 vs. (75.5±21.1) cm~2,P=0. 000], serum triglyceride [(1.98±0.94) mmol/L vs. (1.22±0.61) mmol/L, P=0.000]were all increased, while serum HDL [(1.23±0.32) mmol/L vs. (1.40±0.37) mmol/L, P=0.002]was decreased in NFLD group. The incidences of over-body fat (68.7% vs. 36.5%, P=0. 000),dyslipidemia (47.0% vs. 21.2%, P=0. 000), abdominal obesity (69.9% vs. 43.5%, P=0.001) and MS (49.4% vs. 9.6%, P=0.000) were obviously increased. But there were no statistical differences in serum TC [(4.93±0.94) mmol/L vs. (4. 73±1.07) mmol/L, P=0.219]and LDL [(3.23±0.80) mmol/L vs. (3. 07±0.89) mmol/L, P=0. 229]between the two groups. Logistic regression showed that high BMI (β=1.268, P=0.000, OR=3.56), over-total body fat percentage (β=0.902, P=0.023, OR=2.47)and the existence of MS (β=1. 664, P=0. 000, OR=5.28) were related to elderly type 2 diabetic patients complicated NFLD. Conclusions The high BMI, over-total body fat percentage are related to elderly type 2 diabetic patients complicated NFLD, and NFLD is probably one of components of metabolic syndrome.

Objective To investigate the value of one-stage lymphatics-venous anastomosis in radical mastectomy of breast cancer to prevent post-mastectomy upper limb lymphedema.Methods Ninety patients requiring radical mastectomy of breast cancer in Tangshan Tumor Hospital Affiliated to North China University of Science and Technology from March 2010 to May 2013 were collected as the objects.They were divided into the control group (45 cases) and the treatment group (45 cases) using block randomized grouping (concealment of allocation).Both groups underwent radical mastectomy of breast cancer, and the treatment group was treated with one-stage lymphatics-venous anastomosis on the basis of radical mastectomy.The operation times, amount of bleeding, hospitalization times, postoperative complications and the numbers of axillary lymph node dissection of the patients in the two groups were compared, and the postoperative upper limb lymphedema incidence rates of the patients in the two groups were compared.Results The operative times of the patients in the treatment group and the control group were (152.82 ± 18.76) min and (78.92 ± 10.33) min respectively, and amount of bleeding were (416.64 ± 94.65) ml and (250.84 ± 63.17) ml, with statistical significances (t =-20.39, P =0.00;t =-4.48, P =0.00).The average hospitalization times of the patients in the treatment group and the control group were (14.91 ± 5.44) d and (13.45 ± 2.36) d respectively, the numbers of axillary lymph node dissection were 14.63 ± 3.37 and 14.37 ± 3.18, the numbers of postoperative complications occurred were 9 cases (20.00％) and 5 cases (11.11％), with no statistical significances (t =-0.47, P =0.64;t =0.75, P =0.46;x2 =1.35, P =0.38).Compared with the control group, the treatment group has lower incidence of upper extremity lymphedema (13.95％ vs.40.91％) and lower swelling degree, with statistical significance (x2 =8.48, P =0.03).Conclusion One-stage lymphatics-venous anastomosis in radical masteetomy of breast cancer can effectively transfer lymph diversion to the venous circulation and reduce the incidence of limb lymphedema, which has significant preventive effect.

OBJECTIVE: To investigate the leukotriene D4 synthase gene A (LTD4S A)-444 C polymorphism in persistent allergic rhinitis (AR) of Chinese Han nationality and to evaluate its relevance to clinical responsiveness of leukotriene receptor antagonist. METHOD: There were 150 patients [87 males, 63 females, average age (38 +/- 14)] diagnosed with persistent AR in Allergy clinic in our hospital from March 2010 to March 2012; 146 healthy controls (78 males, 68 females, mean age (39 +/- 12)). We detected LT D4SA-444C polymorphism and allele frequencies with Polymerase Chain Reaction (PCR) and-Restriction Fragment Length polymorphism (RELP). The treatment group received monotherapy leukotriene receptor antagonist (montelukast) for 4 weeks. Urinary leukotriene D4 (LTD4) levels were detected by enzyme-linked immunosorbent assay (ELISA) before and after treatment, respectively. We evaluated anti-leukotriene treatment response according to the changement of symptoms, signs PTS and urinary LTD4. We tested correlation between LT D4S gene-444C allele frequency and the treatment response by multivariate analysis of variance. RESULT: (1) LTD4S gene-444 genotype AA/CC, AC/CC frequency is 70.7% (106/150) and 29.3% (44/150), allele A, C frequencies is 67.3% (101/150) and 32.7% (49/150) in AR group, and LTD4S gene-444 genotype AA/CC, AC/CC frequency is 76.7% (112/146) and 23.3% (34/ 146), allele A, C frequencies is 74.0% (108/146) and 26.0% (38/146) in healthy control group, there is not statistically significant difference between two groups. (2) Among 150 AR patients, compared to patients with AA/CC genotype, the genotype AC/CC patients are younger [average age (35 +/- 9), and (50 +/- 18) respectively, F = 5.891, P < 0.05], with earlier age of onset [(31 +/- 4), and (46 +/- 6) respectively, F = 6.985, P < 0.05], longer course of disease [(8.7 +/- 2.1), and (3.1 +/- 2.0) respectively, F = 11.43, P < 0.05], higher symptom scores (8.2 +/- 0.2; 4.8 +/- 0.3), higher signs score (7.3 +/- 3.3; 3.4 +/- 5.1), and the difference was statistically significant. (3) After 4 weeks of montelukast treatment in AR patients, treatment response of anti-leukotriene in genotype AC/ CC patients is better than those in AA/CC genotype patients (F = 11.01, P < 0.05), the differences of treatment response between two groups were correlated with LTD4 levels in vivo, clinical symptoms and signs of patients. CONCLUSION In a Chinese Han population the LTD4SA-444B polymorphism might be one of the factors in the clinical response to leukotriene receptor antagonists in persistent AR patients.

We constructed inducible and constitutive heterotrophic expression vectors of Dunaliella salina (D. salina) and identified heterotrophic transformants. A gene encoding a glucose transporter (Glut1) was cloned from human placenta tissues by RT-PCR and sequenced. Inducible heterotrophic expression vector pMDDGN-Bar of D. salina, which included a duplicated carbonic anhydrase (DCA) promotor and a Bar selectable marker that could drive expression of the Glut1 gene in D. salina, was constructed by molecular biology methods. In addition, we constructed another vector G5Glut1-Bar that contained a constitutive ubiquitin promotor, Glut1 and Bar box. The two expression vectors were introduced into D. salina by electroporation method, and then screened the transformants with phosphinothricin (PPT). Total RNA of the transformants extracted was used to analyze the integration of the target gene (Glut1) by RT-PCR. The cloned Glut1 sequence was 1479 bp and encoded 493 amino acids. The results of all enzymes digesting showed that two expression vectors were successfully constructed. After screening by PPT for several weeks, the transfomants grew well whereas wild-type cells died completely. The result of RT-PCR indicated that two transformants both had an about 250 bp specific band and the sequence homology was 100% compared with the human Glut1 sequence by Blast analysis. Taken altogether, inducible and constitutive heterotrophic expression vectors of D. salina was constructed successfully and the Glut1 gene was integrated into the genome of D. salina. Expression vectors above-mentioned may be used for the expression of the foreign Glut1 gene in D. salina.

Insufficient intracellular fat oxidation is an important contributor to aging-related insulin resistance, while the precise mechanism underlying is unclear. AMP-activated protein kinase (AMPK) is an important regulator of intracellular fat oxidation and was evidenced to play a key role in high-glucose and high-fat induced glucose intolerance. In the present study, we investigated whether altered AMPK expression or activity was also involved in aging-related insulin resistance. Insulin sensitivity of rats' skeletal muscles was evaluated using in-vitro glucose uptake assay. Activity of alpha subunit of AMPK (AMPKalpha) was evaluated by measuring the phosphorylation of both AMPKalpha (P-AMPKalpha) and acetyl-CoA carboxylase (P-ACC), while expression of AMPKalpha was assessed by determining the mRNA levels of AMPKalpha1 and AMPKalpha2, and protein contents of AMPKalpha. Compared with 4-month old rats, 24-month old rats exhibited obviously impaired insulin sensitivity. At the same time, AMPKalpha activity significantly decreased, while AMPKalpha expression did not alter during aging. Glucose transporter 4 expression also decreased in old rats. Compared with 24-month old rats, administration of the specific activator of AMPK, 5-aminoimidazole-4-carboxamide riboside (AICAR), significantly elevated AMPKalpha activity and GluT4 expression. Also, aging-related insulin resistance was significantly ameliorated by AICAR treatment. In conclusion, aging-related insulin resistance is associated with impaired AMPKalpha activity and could be ameliorated by AICAR, thus indicating a possible role of AMPK in aging-induced insulin resistance.
