Objective To investigate the relationship between intra-abdominal fat area(IAFA)in male with abdominal obesity and glycometabolism related indicators. Methods Ninety-four obesity males,aged from 21 to 62 years old,were selected as our subjects. They were divided into abdominal obesity group(n = 70)and non-abdominal obesity group( n = 24). The general information of all subjects was recorded. The indexes of height,weight,waist circumference,hip circumference,body mass index(BMI)were measured. The fasting oral glucose tolerance test was performed. The levels of blood glucose(0,1,2 h)and insulin(0,1,2 h)were measured,and insulin resistance index was calculated. MRI measurement was applied to calculate the IAFA. Compared the difference between the two groups in term of the level of blood glucose,insulin and insulin resistance index,and analyzed the correlation between glycometabolism related indicators and IAFA. Results BMI,waist circumference,hip circumference,insulin resistance index and IAFA in abdominal obesity group were (28. 67 ± 4. 20)kg/ m2 ,(99. 75 ± 4. 07)cm,(104. 42 ± 7. 62)cm,2. 60 ± 1. 80,(153. 06 ± 53. 23)cm2 respectively,higher than those in non-abdominal obesity group((21. 80 ± 1. 97)kg/ m2 ,(79. 50 ± 10. 05)cm, (91. 86 ± 4. 49)cm,1. 52 ± 0. 73,(71. 78 ± 25. 48)cm2 ),and the differences were statistically significant(t= - 7. 704,- 9. 583,- 7. 618,- 2. 877,- 7. 184,P < 0. 05). The level of blood glucose at 0,1,2 h of patient in abdominal obesity group were(5. 89 ± 1. 36)mmol/ L,(10. 55 ± 3. 07)mmol/ L,and(8. 41 ± 3. 63) mmol/ L,higher than that in non-abdominal obesity group((5. 29 ± 0. 53)mmol/ L,(8. 76 ± 1. 96)mmol/ L, (6. 54 ± 1. 50)mmol/ L). Meanwhile,The insulin at 0,1,2 h of man in abdominal obesity group were(9. 71 ± 5. 05)mU/ L,(83. 29 ± 64. 51)mU/ L,(63. 56 ± 21. 09)mU/ L),significantly higher than those in non-abdominal obesity group((6. 42 ± 2. 96)mU/ L,(33. 00 ± 19. 82)mU/ L,(63. 56 ± 21. 09)mU/ L),and the differences were significant( t = - 2. 098,- 2. 671;- 2. 447,- 3. 010;- 3. 784,- 3. 089;P < 0. 05). The IAFA in abdominal obesity was positively correlated with age,BMI,waist circumference,hip circumference,blood glucose(0,1,2 h)insulin(0,2 h)and insulin resistance index(r = 0. 254,0. 533,0. 521,0. 615,0. 245,0. 315, 0. 294,0273,0. 249,0. 225,P < 0. 05 ). After adjustment for confounding factors,age( x1 ),abdominal circumference(x2)and insulin resistance index(x3)were related to IAFA(y = 1. 369x1 + 4. 472x2 + 25. 072x3- 333. 626). Conclusion Compared with patients with non-abdominal obesity,the IAFA of patient with abdominal obesity with abdominal fat area size is associated with insulin resistance.

Aim To investigate the release feature of ginsenoside Rd solid lipid nanoparticles (Rd-SLN) in vitro,and to clarify the difference in absorption of Rd-SLN from varied rat intestinal segments and pharmacokinetic properties in vivo. Methods Dialysis method was used to determine ginsenoside Rd release rate from nanoparticles in vitro. Perfusion method was used to study the intestinal absorption of Rd-SLN in rat. HPLC assay was established to determine the concentration of ginsenoside Rd in plasma. After intragastric administration,the concentrations of drug in rat blood at different time points were recorded to investigate the absorption and pharmacokinetics of Rd-SLN. Results The release of ginsenoside Rd from Rd-SLN was slowed down and presented the property of sustained release. There was no significant difference between the absorption rate of Rd-SLN and control solution in duodenum and jejunum. However,it was obviously different in ileum and colon. Comparing with other intestinal segments,significantly higher percentage of Rd-SLN was absorbed in colon. In Rd-SLN group,the concentration of ginsenoside Rd in blood was maintained,and the Cmax,MRT,AUMC,and AUC were all increased. Conclusions Rd-SLN possesses sustained-release effect. The colon is the preferable absorption site for Rd-SLN in intestinal tract. Rd-SLN can enhance the oral bioavailability of ginsenoside Rd.

Objective To investigate the effects of tongue cancer resistance-associated protein 1 (TCRP1) in proliferation of chronic myeloid leukemia cells (CML),and explore the new thoughts of pathogenesis of CML.Methods The expression of TCRP1 was detected in the peripheral blood mononuclear cells (PBMC) of CML with real-time quantitative polymerase chain reaction (PCR) and Western blot.After the expression of TCRP1 was interfered in K562 cells,the proliferation of cells was detected by 3-(4,5-dimenthylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) assay and soft agar colony forming assay,and the expression of protein kinase B (AKT) and its phosphorylation were tested by Western blot.Results In PBMC of CML patients,the mRNA and protein levels of TCRP1 were significantly higher than those of normal controls.The results of MTS assay and soft agar colony forming assay showed that the proliferation of K562 cells was significantly decreased after the expression of TCRP1 was interfered.After knockdown of TCRP1 in K562 cells,the phosphorylation of AKT was significantly decreased while the expression of total AKT did not change.Conclusions The expression of TCRP1 was increased in CML cells.High expression of TCRP1 might contribute to proliferation of K562 cells via the phosphorylation of AKT.

Objective To compare the number of lymph node dissected by intraoperative lymphatic mapping guided D2 gastrectomy and that by standard D2 gastrectomy plus lymphadenectomy in patients of advanced gastric cancer. Methods In this study 20 advanced gastric cancer cases received intraoperative peritumor injection of carbon nanoparticles suspension ( group 1 ) and D2 lymphadenectomy was guided by the black-stained lymph nodes. 21 cases undergoing standard D2 lymphadenectomy served as controls (group 2). The number of lymph nodes removed and the condition of lymphatic metastasis in two groups, blackstained lymph nodes in group 1, and postoperative complications were compared. Results The average lymph nodes dissected in group 1 (35. 1 ± 13.4) were higher than in control group (26.2 ±7.8). The differences were statistically significant (t =2. 126, P =0. 034). The number of removed N2 and N3 lymph nodes in group 1 were more than that in control group. The total black-stained ration of lymph nodes was 52. 7% in group 1. The positive rate of lymph nodes was higher in black-stained lymph nodes (27.6%) than in unstained lymph nodes ( 10. 8% ) in group 1 and in control group ( 16. 9% ). The differences were also statistically significant ( x2 = 6. 034, P = 0. 016; x2 = 5. 142, P = 0. 023 ). Postoperative afferent loop obstruction developed in one case in group 1. Conclusions Lymphatic mapping guided D2 radical gastrectomy plus lymphadenectomy increases the number of lymph nodes dessected and improves the efficiency of positive lymph nodes excision for patients of advanced gastric cancer.

Objective To observe the effects of intensive insulin treatment on islet β cell apoptosis associated protein bcl-2 and bax in type 2 diabetic rats.Methods 36 Wistar rats were randomly divided into two groups : normal control group and high fat diet group.Rats in normal control group fed by basical feedstuff.Rats in high fat diet group fed by high fat and basical feedstuff.After 10 days,rats in high fat group were injected with STZ.After 3 days,rats in high fat group were randomly divided into two groups:diabetes control group and insulin treatment group.The course of treatment was 4 weeks.After 10 days by fat milk intragastfic administration, after 3 days of STZ injection and after 4 weeks treatment, each index was measured.After experiment, pancreatic tissue bel-2 and bax were detected through immunohistocbemical method.Results After 4 weeks intensive insulin treatment,the bcl-2 was significantly increased at(6.20 ± 2.05 )% in insulin treatment group than diabetes control group.The bax was significantly decreased at ( 2.68 ± 1.04 ) % in insulin treatment group than diabetes control group ( P < 0.05 ).Conclusion The method of insulin intensive treatment could increase islet βcell bcl-2 and decrease bax in type2 diabetic rots, Insulin intensive treatment could decrease islet β cell apoptosis.

Among 78 cases ,29 cases were bulbar urethral trauma and other 49 cases were membranous urethral trauma.Conclusion Retrograde urethrography is simple, practical and easy to operate for determining the injured part of urethra and the extent of damage of urethraltrauma, and was instructional for the choice of operation method and incision.

Objective To analyze the efficacy and safety of HAA induction regimen consisted of homoharringtonine (HHT),cytarabine (Ara-C) and aclacinomycin (ACM) in naive and refractory relapsed acute myeloid leukemia.Methods Data from 66 acute myeloid leukemia (AML) cases hospitalized and treated with HAA induction regimen was analyzed retrospectively.Results 45 of the 66 cases suffered from naive AML,and 21 were refractory relapsed.HAA efficacy in naive AML was evaluated in 41 cases with 36 in complete remission (CR) and 1 in partial remission (PR).The efficiency of HAA induction regimen was 90.2 ％ (37/41)in naive AML group and 42.9 ％ (9/21) in refractory relapsed group,respectively.There were no differences (P ＞ 0.05) when considering patient' s gender,age,disease subtype and white blood cell count at onset.14 patients in CR with naive AML were followed-up for a median time of 9 months (2-17 months),and 5 cases relapsed (35.7 ％) in a range of 2-8 months.The median myelosuppression period was 14 days (3-23 days).Nausea and vomiting [20 ％ (13/66)] were the major side effects of HAA regimen,and the other side effects were abdominal pain and diarrhea [9 ％ (6/66).After chemotherapy,53 ％ (35/66) of the cases experienced infection/fever due to neutropenia.Other severe non-hematological side effects did not occur.Conclusion HAA regimen may be an ideal choice for the induction chemotherapy of naive and relapsed refractory AML.

Objective To study the changes in interleukin-32 (IL-32) in rats with Klebsiella bacillus pneumonia and approach its significance. Methods Seventy-two Sprague-Dawley(SD)rats were divide into control group,model group and experimental group by the method of random digits table,then the experimental group was subdivided into 4 hours and 1,3 and 5 days experimental subgroups(each n=6). The rat model of Klebsiella bacillus pneumonia was established by injection of 0.3 mL Klebsiella bacterial suspension into the trachea. Before the establishment of the model in the experimental group,IL-32 inhibitory agent,protease activated receptor-2(PAR2) was injected into the abdominal cavity. After model establishment,at different time points,blood was collected via tail vein to observe the changes in serum levels of IL-32,tumor necrosis factor-α(TNF-α),IL-6 and IL-8 in all the groups. The lungs were removed and stained with hematoxylin-eosin(HE)method to investigate the histopathological changes of the lung tissues under the light microscope. Results Compared to the control group, with the prolongation of time the levels of IL-32,TNF-α,IL-8 and IL-6 were increased gradually in the model group,and reached their peaks at 3 days〔IL-32(ng/L):84.40±28.24 vs. 18.57±3.86,t=5.544,P=0.002;TNF-α(ng/L):79.27±14.64 vs. 17.82±3.86, t=9.994, P=0.000;IL-8(ng/L):55.85±10.90 vs. 16.66±3.76,t=8.544, P=0.000;IL-6(ng/L):56.65±2.57 vs. 28.48±2.11,t=19.693,P=0.000〕;PAR2 could inhibit above indexes significantly,there was statistical difference at 3 days compared with the model group〔IL-32(ng/L):54.13±6.68 vs. 84.40±28.24,t=2.560,P=0.046;TNF-α(ng/L):49.12±3.56 vs. 79.27±14.64,t=4.901,P=0.003;IL-8 (ng/L):22.95±2.52 vs. 55.85±10.90,t=7.204,P=0.000;IL-6(ng/L):36.49±2.63 vs. 56.65±2.57,t=13.443, P=0.000〕. Under the light microscope,the inflammatory changes in the lung tissue in experimental group were milder than those in the model group. Conclusion As a pro-inflammatory cytokine,IL-32 can induce the production of TNF-α,IL-6 and IL-8,and the inhibition of IL-32 production may play a role in suppression of the development of Klebsiella bacillus pneumonia.

[Summary] To investigate the correlation of serum alanine aminotransferase (ALT) level with impaired fasting glucose (IFG) and evaluate the modification effects of body mass index in Chinese adults.The study samples were from a community-based health examination survey in Xuzhou,Jiangsu province of China.A total of 32 433 subjects with biomarkers available were included in the present study.Serum ALT,triglyceride,total cholesterol,high density lipoprotein-cholesterol,low density lipoprotein-cholesterol,and glucose levels were measured.IFG was defined as from 6.1 mmol/L to 7.0 mmol/L.Results are expressed as x±s.The correlation between serum ALT and impaired fasting glucose was assessed using logistic correlation.The correlation of serum ALT and IFG in the group of fasting blood glucose was segnificantly (r=0.07,P＜0.01),while the correlation with the normal blood glucose group fasting blood glucose is weak (r=0.001,P＞0.05).After adjusted for age,sex,and body mass index,there was a strong correlation between the fasting blood glucose (r =0.04,P＜0.01) in ALT and IFG group.After further adjustment for serum lipids,blood pressure,this correlation still exists (r =0.03,P＜0.01).Body mass index influences correlation of ALT and IFG.The present data indicate that the serum ALT is related to the risk of IFG in Chinese adults,and body mass index level may affect the relationship.
