Visfatin was recently reported as an adipokine and was found to exert insulin-mimicking effects.The results showed that the expression of visfatin parallelled with obesity and insulin resistance in long term high fat chow-fed rats.The expression of visfatin mRNA was decreased and the insulin resistance improved after rennin-angiotensin system was blocked.Visfatin may play an important role in the pathogenesis of insulin resistance.

Objective To evaluate the incidence and significance of perineural invasion (PNI) in cervical cancer. Methods Retrospective chart review of patients with cervical cancer (stages Ⅰa2-Ⅱb) who underwent radical hysterectomy and pelvic lymphadenectomy from 2007 to 2012. To evaluate the incidence and significance of PNI in cervical and uterine tissues by microscopic examination. Results A total of 238 patients were included, 9.2% (22/238) patients with PNI in the cervical stroma. Patients with PNI were more likely to have adverse histopathologic features, including lymphoma vascular space invasion, parametrical invasion, depth of invasion, tomor size and lymph nodes metastases (all P<0.05). PNI were independent of age, international federation of gynecology and obstetrics (FIGO) stage, histopathology type and grade, and positive vaginal margin (all P>0.05). Patients with PNI had shorter disease-free and overall survival (P=0.002 and P=0.008, respectively). On multivariate analysis, risk factors for recurrence and death included parametrical invasion and depth of invasion (P<0.05). Similarly, risk factors for recurrence included lymph nodes metastases (P=0.024). However, PNI was not identified as an independent risk factor for either recurrence or death (P>0.05). Conclusions PNI exists in early cervical cancer. PNI is associated with tumor size, depth of invasion, parametrical invasion, lymphoma vascular space invasion and lymph nodes metastases. PNI represente a decreasing disease-free and overall survival in patients with early-stage cervical cancer, and is independently associated with multiple high-risk factors, which be informed management decisions regarding adjuvant therapy.

Objective To study influencing factors for giving up chemotherapy during initial treatment in elderly patients with multiple myeloma.Methods A total of 156 elderly patients diagnosed as multiple myeloma from 2000-2010 were retrospectively analyzed.And 123 young patients with multiple myeloma were selected as control group.The causes for giving up the chemotherapy and its related factors were recorded and analyzed.Results The rate of giving up the initial chemotherapy was higher in the elderly than in young patients [58.3％ (91/156) vs.35.0％ (43/123),P＜0.05].51.7％ of the elderly patients did not accept chemotherapy after diagnosis.The main factors for giving up the initial chemotherapy in elderly patients were critically ill,economic difficult and the low tolerance.However,the economic difficulty was the first cause in the young group.Conclusions The rate of giving up the chemotherapy in the elderly patients is high.Old age,severe conditions,economic difficulty,and low tolerance are the independent factors.

Objective To investigate the expression and the significance of toll-like receptor 3 (TLR-3)in placenta,tumor necrosis factor-α(TNF-α)in maternal and cord blood of idiopathic fetal growth restriction(IFGR),and their correlation with the pathogenesis of symmetric and asymmetric IFGR.Methods From April 2008 to April 2009,42 primiparae of singleton pregnancy and their IFGR babies,who delivered at term through cesarean section, in the Third Affiliated Hospital of Zhengzhou University were enrolled. All subjectects were divided into symmetric IFGR group (n=20) and asymmetric IFGR group (n =22). Another 42 non-IFGR pairs were randomly selected as the control group. The polink-2 plus polymerized horseradish peroxidase (HRP) immunohistochemical method and the enzyme linked immunosorbent assay (ELISA) were applied to detect TLR-3 and TNF-α levels. Results (1) The expression of TLR-3 protein were observed in all maternal placenta of the three groups. TLR-3 essentially expressed in syncytiotrophoblasts and hofbouer cells in the symmetric IFGR and control group, but expressed mostly in hofbouer cells and less in syneytiotrophoblasts in the asymmetric IFGR group. (2) The expression of TLR-3 in the syncytiotrophoblasts of the symmetric and asymmetric IFGR group was significantly lower than in the control group (111±14 and 118±11 vs. 156 ± 9, P<0. 01). The number of TLR-3 positive in Hofbourer cell in the symmetric IFGR group was lower than the control group (8. 9±2. 8 vs 17.5±2. 8, P <0. 01 ), but the number in the asymmetric IFGR group was higher (23.8±3.7) compared with the control group (P <0. 01). (3) The TNF-α levels in the maternal and cord blood of the symmetric and the asymmetric group were higher than that of the control group [maternal : (90±10) μg/L and ( 86±11 ) μg/L vs. (73±9) μg/L;cord blood: (92±12) μg/L and (96±8) μg/L vs. (79±9) μg/L;P<0.01]. (4) Neither symmetric nor the asymmetric IFGR group showed any correlations between the maternal and cord blood levels of TNF-α (P>0. 05). (5) Significant correlation was found between the TNF-α level of the cord blood and TLR-3 expression in the placenta in both the symmetric and asymmetric IFGR group(P<0. 05),but no relationship was found between the maternal blood TNF-α level and TLR-3 expression in the placenta (P>0. 05). Conclusions The variantions of TLR-3 expression in placenta and the increased expression of TNF-α in cord blood are associated with the genesis IFGR. The reduced expression of TLR-3 may related to symmetric IFGR, while the increased TLR-3 level in hofbouer cells may lead to asymmetric IFGR.

Objective To investigate the relationship between lipid fluctuations of daily diet and insulin resistance in patients with type 2 diabetes mellitus(T2DM) with normal fasting lipid profile. Methods One hundred and ninety?eight cases patients with T2DM who were treated in the Endocrinology Department of the General Hospital of Benxi Iron and Steel Group Corporation from October 2012 to September 2014 were selected. Patients were divided into three groups according to fasting and postprandial 4 h triglyceride( TG4 h)
level,the group with normal fasting TG and normal TG4 h with 38 cases,the group with normal fasting TG and rising TG4 h with 78 cases,the group with rising fasting TG and rising TG4 h with 82 cases. The control group was composed of healthy volunteers with 20 cases. The patients followed daily diet habits to eat,blood glucose, insulin and lipid level of fasting and 2 h,4 h after lunch were monitored. Homeostasis model insulin resistance index( HOMA?IR) was used as an index to evaluate insulin resistance,and the correlation analysis was carried out with fasting and dietary intake of postprandial lipid metabolism. Results (1)HbA1c,FPG,HOMA?IR,TG and insulin level in the patients of the group with normal fasting TG and normal TG4 h,the group with normal fasting TG and rising TG4 h,the group with rising fasting TG and rising TG4 h were higher than the control group (HbA1c:(8. 4±1. 9)%,(8. 2±2. 4)%,(7. 8±1. 8)% vs. (4. 3±0. 6)%);FPG:(8. 98±1. 93) mmol/L, (8. 62±1. 33) mmol/L,(8. 28±1. 26) mmol/L vs. (4. 82±0. 63) mmol/L;,HOMA?IR:11. 07±0. 11,6. 98 ±0. 08,3. 83±0. 09 vs. 1. 24±0. 16;TG:0 h TG:(2. 35±1. 85) mmol/L,(1. 60±0. 41) mmol/L,(1. 58±0. 46) mmol/L vs. (0. 82±0. 25) mmol/L;2 h TG:(3. 97±2. 96) mmol/L,(2. 98±1. 49) mmol/L,(1. 83±0. 62) mmol/L vs. (1. 22±0. 31) mmol/L;4 h TG:(4. 24±1. 57) mmol/L,(3. 15±1. 63) mmol/L,(1. 92±0. 53) mmol/L vs. (1. 16±0. 24) mmol/L;insulin(0 h insulin:(26. 51±3. 65) mU/L,(18. 18±6. 24) mU/L,(10. 31 ±2. 38) mU/L vs. (5. 87±1. 62) mU/L;2 h insulin:(59. 15±8. 34) mU/L,(43. 75±9. 83) mU/L,(34. 27 ±1. 61) mU/L vs. (25. 24±1. 98) mU/L;4 h insulin:(51. 22±6. 79) mU/L,(40. 06±7. 51) mU/L,(31. 06 ±1.77) mU/L vs. (13.36±1.37) mU/L;P<0.05). (2)WHR(0.90±0.08 vs.0.72±0.06),HOMA?IR, insulin level of fasting and 2 h,4 h after lunch,TG of 2 h,4 h after lunch in the group with normal fasting TG and rising TG4 h were higher than the group with normal fasting TG and normal TG4 h ( P<0. 05 ) . ( 3 ) BMI ((27. 3±3. 3) kg/m2 vs. (23. 1±1. 5) kg/m2),WHR(0. 96±0. 10 vs. 0. 72±0. 06),HOMA?IR,TG and insulin level of fasting and 2 h,4 h after lunch in the group with rising fasting TG and rising TG4 h were higher than the group with normal fasting TG and normal TG4 h( P<0. 05) . HOMA?IR,TG and insulin level of fasting and 2 h, 4 h after lunch in the group with rising fasting TG and rising TG4 h were higher than the group with normal fasting TG and rising TG4 h( P<0. 05) . ( 4) HOMA?IR was positively correlated with BMI,WHR,and fasting TG levels in the groups with diabetes(r=0. 297,0. 376,0. 326,P<0. 05). HOMA?IR was significantly positively correlated with TG of 2 h,4 h after lunch in the groups with diabetes( r=0. 529,0. 693,P<0. 05) . HOMA?IR was significantly positively correlated with BMI and WHR in the control group(r=0. 617,0. 728,P <0. 05). HOMA?IR was not significantly correlated with fasting and postprandial TG in the control group. Conclusion Postprandial lipid metabolism disorder after daily diet is in some of patients with T2DM with normal fasting lipid profile. Postprandial lipid metabolism disorder after daily diet is significantly positively correlated with insulin resistance in patients with T2DM. Insulin resistance may be one of the pathogenesis of postprandial dyslipidemia in patients with type 2 diabetes.

SUMMARY To investigate the effect and feasibility of total laparoscopy to treat hepatolithiasis using gall-bladder-hepatic duct subcutaneous tunnel.Retrospective analysis was conducted of the case data of 11 pa-tients with hepatolithiasis who underwent total laparoscopic treatment using gallbladder-hepatic duct sub-cutaneous tunnel from January 2010 to October 2014.The operation time,blood loss,postoperative com-plications and recurrence of stones were recorded.All the cases completed the operation.The average hos-pital-stay was 9.2 days (range:3 -29 d).The average operation time was 298 min (range:225 -480 min).The average blood loss was 253 mL (range:50 -700 mL),and the average blood loss of liver re-section groups was 325 mL (range:200 -700 mL).The average discharge time was 3.3 days (range:3 -5 d).The rate of postoperative residual stones was 36.4% (4 /11).We extracted stones with chole-dochofiberscope via T-tube sinus six weeks after operation.One case developed biliary leakage,and healed through adequate drainage and the T-tube was pulled out after one month.There was no periopera-tive mortality.All the cases were followed up and the mean follow-up was 22 months (range:2 -51 months).The anastomotic stenosis of gallbladder-hepatic duct was found in one case.But we got a good therapeutic result with performed gallbladder chemical ablation with 95% ethanol.No recurrence of hepa-tolithiasis was found.As a choice for minimally invasive method to hepatolithiasis using gallbladder-he-patic duct subcutaneous tunnel,total laparoscopy is a safe and feasible procedure.

Objective To investigate the morphological features of normal lumbar dorsal root ganglia using a three-dimensional(3D)coronal MR imaging.Methods One hundred and fifteen volunteers were included.Ages ranged from 15 to 75 years,with a mean of 40 years.Coronal 3D fast field echo(FFE) with water selective excitation(Proset)MR examination of 1150 dorsal root gangha were underwent at nerve root levels from L1 to L5.The source coronal images were further reconstructed into a series of rotational alignment coronal images with an interval angel of 12 degree using maximum intensity projection(MIP) technique.All DRGs of bilateral spinal nerve from L1 to L5 were morphologically analyzed on the original and MIP images including qualitative evaluation of the location,signal intensity,architecture and quantitative dimensional measurement.Results There were 225,225,219,210 and 160 foraminal ganglia from L1 to L5 level,respectively.The incidence of intraspinal ganglia from L3 to L5 gradually increased with a maximum at L5 level of 29.1%(X~2=188.371,P
