Objective:To evaluate magnetic resonance (MR) indirect lymphography for lymph node metastasis of cervical cancer diagnosis value.Methods: One hundred and eight cases of the 2009-2013 hospital admission of patients with cervical cancer, magnetic resonance indirect lymphography for sentinel lymph node imaging, pelvic lymph drainage situation of observation, the patients underwent total hysterectomy and pelvic lymphadenectomy.Results: The experimental results show that interstitial magnetic resonance lymphography judgment patients with cervical cancer lymphmetastasis accuracy was 96.30% (104/108), the sensitivity was 78.95% (15/19), no significant difference with the pathological examination results (t=0.89,P>0.05). The determination of interstitial magnetic resonance lymphography for lymph node metastasis of uterine cervix cancer prediction accuracy rate is high,play an important role in the preoperative diagnosis of uterine cervical cancer.Conclusion:MR indirect lymphography for cervical cancer patients can appear pelvic draining lymph node anatomy, regional lymphatic, and evaluation of sentinel lymph node status and diagnosis of cervical cancer with lymph node metastasis or not is feasible and effective.

Objective To investigate the infiltration of inflammatory cells and the pathogenesis of nasal polyps. Methods the nasal polyps were obtained from 42 patients undergoing nasal operations. The tissues from each patient were stained with HE and Toluidine Blue for eosiophils, lymphocyte, plasma cell and mast cell and observed under the light microscope. A mean number of the above cells were counted. All data were analyzed with the Ttest. Results Eosinophils were found predominantly in 12 polyps(28.57％). Lymphocyte infiltration was shown in the other 30 polyps (71.43％). Furthermore, many mast cells with only a few eosinophils were found in the lymphocyte infiltration polyps; the number of mast cells in these polyps were much more than those in eosinophil accumulation polyps with a very significant difference(P＜0.01). Conclusion The accumulation of eosinophils in the nasal polyps does not appear to be related to the presence of mast cells and allergy. The disorder of immunity may play an important role in the formation of nasal polyps.

Objective To investigate the change of renal 1-alpha hydroxylase and its effect on bone mineral density in the old rats with type 2 diabetic nephropathy. Methods Forty Wistar rats of 18 months old were randomly divided into normal control (N), diabetes (D), diabetes treated with vitamin D_ 3 (T1) and diabetes treated with 1-?(OH)D_ 3 (T2) groups, respectively. Ten rats in each group. Dual energy X-ray absorption (DEXA) was used to determine bone mineral density (BMD) of lumbar spines and femoral bone. 24 h urinary protein excretion, serum 25(OH)D_ 3 and 1,25(OH)_ 2 D_ 3 were measured by radioimmunoassay. Results Compared with controls, 24 h urinary protein excretion increased remarkably D, T1, T2 groups, while BMD greatly decreased, much lower in D group and T1 group than T2 group (P0.05). The level of 1,25(OH)_ 2 D_ 3 in N group was the same to T2 group, but higher than D, T1 groups (P

Objective To explore the correlation between serum brain natriuretlc peptide(BNP) and cardiac function in children with pneumonia.Methods Fifty-two children with pneumonia were seleated.Among them 20 were complicated with congestive heart failure(CHF),including 9 boys and 11 girls,their ages ranging from 4 months to 4 years old;and 32 cases non-complicated with CHF,including 17 boys and 15 girls,their ages ranging from 5 months to 6 years old.Besides,there were 30 healthy children as control group,including 16 boys and 14 girls,their ages ranging from 6 months to 5 years old.For all the children,their serum BNP was measured by using ELISA met-hod,and CK-MB was measured by automatic biochemistry analyzer.In the sametime,their cardial function was measured by echocardiography.Results In the children with pneumonina complicated with CHF,the levels of serum BNP[(182.45?57.32) ng/L] and CK-MB [(48.19?16.08) IU/L] were higher than those of healthy control group[(35.12?13.84) ng/L,(11.48?4.29) IU/L Pa0.05).The levels of left ventricular ejection fraction(LVEF),left ventricle shortening fraction(FS),peak flow velocity of arteriae arota(PFVA),peak flow velocity of pulmonary artery(PFVP) in the children with pneumonia complicated with CHF were lower than those of healthy control group(Pa0.05).There was a positive correlation between the levels of serum BNP and CK-MB(r=0.28 P0.05).Conclusion The levels of serum BNP may be an important index in diagnosis of infant pneumonia complicated with CHF.

To evaluate the influence of phacoemulsification on corneal endothelium of senile cataract with lupus nephritis (LN).
●METHODS:This clinical trial involved 40 cataract patients with lupus nephritis (40 eyes), and 50 cases (50 eyes) without lupus nephritis. All of them underwent phacoemulsification+lOL implantation. The parameters of corneal endothelial cell including central corneal endothelium cell density ( CED ), average area of endothelial cell ( AVE) and coefficient of variation ( CV) were recorded by corneal endothelial microscope pre -operation and at one month after operation. The data were analyzed by SPSS 13. 0 statistical software.
● RESULTS: Both LN group and control group, the morphology of coneal endothelial was statistical significant differences between pre - operation and 1mo postoperation. The CED was lower, AVE and CV were higher ( P < 0. 05, respectively). A significant decrease in CED was seen in the LN group than did in the control group (P < 0. 05). Compared to control group,the post -operative AVE and CV in LN group was significantly increased (P<0. 05).
● CONCLUSlON: The corneal endothelial cell in lupus nephritis patients is more fragile. Safe and reliable operation should be selected for these patients.

BACKGROUND: Interleukin-17A has been shown to play an important role in nerve regeneration following corneal injury. OBJECTIVE: To investigate the effect of interleukin-17A on mouse nerve regeneration after optic nerve injury.METHODS: The interleukin-17A-overexpressed adenovirus vector (AV-IL-17A-GFP) was constructed and purified. Adenoviruses with green fluorescent protein (AV-GFP) served as control group. PC12 cell lines were transfected with adenoviruses and the expression efficiency of IL-17A were detected by ELISA. The adenovirus was intravitreally injected into the mouse vitreous body, and the expression level of IL-17A in the optic nerve was determined by immunofluorescence. Afterwards, a mouse model of optic nerve injury was established to observe the nerve regeneration. RESULTS AND CONCLUSION: ELISA results showed that IL-17A was highly expressed in the PC12 cell lines transfected with AV-IL-17A-GFP compared with the control group.Immunofluorescence results revealed that IL-17A was expressed in vivo successfully.There was a significant increase in the number of regenerated axons in the AV-IL-17A-GFP group compared with the control group (P < 0.05). To conclude,AV-IL-17A-GFP can be expressed in the mature neurons in vivo and promote the axon regeneration after optic nerve crush injury in mice.
