Objective To explore the pancreatic kininogenase enteric-coated tablets in the treatment of diabetic retinopathy (DR) patients and its effect on the optic disc and macula retinal hemodynamics. Methods 86 cases (140 eyes) of DR patients were randomly divided into pancreatic kininogenase group and normal group with 43 cases in each group, two groups were treated with basic therapy, pancreatic kininogenase group were combined with pancreatic kininogenase treatment. The best corrected visual acuity and the clinical effect of optic disc and macula retinal hemodynamic changes were compared between two groups. Results After treatment, the best corrected visual acuity (BCVA) in pancreatic kininogenase group was greater than the normal group (P<0.05), the retinal neovascularization and fluorescein leakage area in pancreatic kininogenase group was less than the normal group (P<0.05). The disc vascular and macular retinal blood flow volume (VOL), blood flow velocity (FLW)values in pancreatic kininogenase group were larger than those of normal group, and the clinical curative effect of pancreatic kininogenase group was better than that of normal group (P<0.05). Conclusion Pancreatic kininogenase enteric-coated tablets in the treatment of DR patients can improve the optic disc and macular retinal hemodynamic parameters, improve visual acuity and reduce the retinal neovascularization and fluorescein leakage area, so as to improve the clinical treatment effect.

Objective To investigate the consistency in 18F-deoxyglucose positron emission tomography (18F-FDG PET-CT) examination and histopathological analyses in the diagnoses of resectable lung tumors. Methods Retrospective reviews over the clinical data of lung tumor patients by preoperative PET-CT diagnosis and postoperative histopathological diagnosis were conducted to investigate the effects of the two diagnostic methods in terms of lung tumor properties , mediastinal lymph node metastasis , and pulmonary hilar lymph node metastasis. Results The diagnoses by preoperative PET-CT was consistent in differentiation of non-malignancy and malignancy of pathologic lung tumors by 87.3%, at a medium level (κ = 0.401, P < 0.001). McNemar test showed P = 0.508, indicating the two diagnostic methods were insignificantly different in the diagnosis of pulmonary tumors. The preoperative PET-CT was consistent in the diagnosis of the metastasis of pathologic mediastinal lymph node by 85.9%, at a medium level (κ = 0.697, P < 0.001). McNemar test showed P =0.754, indicating no significant difference between the diagnostic methods. The preoperative PET-CT was consistent with postoperative pathological examinations in the differentiations of the metastasis of pulmonary and hilar lymph node by 77.4%, at a medium level (κ=0.523, P < 0.001). McNemar test showed P = 0.454, indicating the two diagnostic methods were no significantly different. Conclusion Preoperative PET-CT and histopathologic examinations may be consistent in lung tumor diagnosis , which provides a basis for a certain significance in the surgical options.

A 44-year-old male presented with a neoplasm on the buccal side of the right nasolabial fold for more than two months.Dermatological examination showed a hemispherical bulge sized 1.5 cm × 1.5 cm with central crater-like ulceration on the buccal side of the right nasolabial fold,as well as a crescent-shaped elevation measuring 1.5 cm × 2.5 cm above the hemispherical lesion.Histopathology of the hemispherical lesion revealed irregularly downward proliferation of epidermis,crater-like holes filled with eosinophilic keratinous plug in the center which were surrounded by collar-shaped epithelial cell projections.Small neutrophil abscesses were found in the clumps of epithelial cells,and massive lymphocyte infiltration with a clear bottom boundary was observed around the proliferating epithelial cells.Histopathologic examination of the crescent lesion showed multiple irregularly-shaped lobular-like structures of various sizes with sebaceous glands at different degrees of maturity in the mid dermis,which were surrounded by proliferating connective tissue.Immunohistochemical studies showed that the squamous cells stained positive for cytokeratin (CK),CK5,CK14,CK17,carcinoembryonic antigen (CEA) and epithelial membrane antigen (EMA) in the keratoacanthoma,and the sebaceous cells for CK,CK5,CK14 and EMA in the sebaceous adenoma.The pathological diagnosis was keratoacanthoma and sebaceous adenoma.The patient was diagnosed with moderately and poorly differentiated rectal adenocarcinoma in 2008.A diagnosis of Muir-Torre syndrome presenting as keratoacanthoma and sebaceous adenoma was finally made.

OBJECTIVETo explore the clinical outcomes of percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) in treating osteoporotic vertebral compression fracture (OVCF).

METHODSFrom January 2007 to February 2010, the data of 40 patients with osteoporotic vertebral compression fracture underwent treatment were retrospectively analyzed. Of them,20 patients were treated with PVP (PVP group), there were 8 males and 12 females with an average age of (66.37 +/- 2.34) years old (54 to 81); 20 patients were treated with PKP (PKP group), there were 11 males and 9 females with an average of (65.12 +/- 3.21) years old (56 to 79). Postoperative at 1 week, 12 weeks, 1 year, pain and daily life function were respectively assessed by visual analogue scale (VAS) and Barthel index (BI); and anterior height of responsibility vertebra, Cobb angle were measured by X-rays.

RESULTSIn PVP group, 1 case complicated with bone cement leakage without clinical symptoms and no operation to treat. No postoperative infection and deep vein thrombosis were found between two groups. All patients were followed up more than 1 year, pain and daily life function has obviously improved than preoperative (P < 0.01); and there was no significant difference on 1 week, 12 weeks, 1 year after operation (P > 0.05); there was no significant difference between two groups (P > 0.05). In PVP group, there was no significant difference in anterior height of responsibility vertebra, Cobb angle before and after operation;and in PKP group, postoperative data has obviously improved than preoperative (P < 0.01), but there was no significant difference postoperative at 1 week, 12 weeks, 1 year (P > 0.05); there was no significant difference between two groups at 1 week, 12 weeks, 1 year after operation.

CONCLUSIONBoth the methods can obviously relieve pain and completely or partly recover daily life function in treating OVCF. But PKP has advantages of recovery of anterior height of responsibility vertebra and correction of Cobb angle, especially for serious compression.

Objective To compare the diagnostic significance of pleural SLPI,IFN-γ and ADA for differenti-ating TPE from pleural effusions with the other etiologies. Methods Pleural effusion samples were obtained from 93 patients who were divided into the following groups: tuberculous pleural effusion,malignant pleural effusion, bacterial pleural effusion and transudative pleural effusion. The pleural effusion and/or serum levels of SLPI , IFN-γand ADA were determined. Results 1.The concentrations of SLPI, IFN-γand ADA in tuberculous pleural effusion was higher than that in malignant group, bacterial group and transudative group. 2. The diagnostic value of SLPI, IFN-γor ADA for the diagnosis of tuberculous PE is high respectively. The combinations of SLPI, IFN-γand/or ADA gained the more valuable diagnostic performance. Conclusion Pleural SLPI, IFN-γand ADA may be helpful for the differential diagnosis of tuberculous pleural effusion and the other pleural effusion. The combinations of SLPI or/and IFN-γor/and ADA further increased diagnostic value.

ObjectiveTo compare the levels of sFas in the sera among Kawasaki disease (KD),incomplete Kawasaki disease (IKD),and normal control groups,and to analyze the relationship of sFas with IKD children.MethodsA total of 32 cases of acute KD and acute IKD children,and 20 cases of the control children were selected,respectively.The levels of serum sFas among three groups were measured using ELISA kits.Each child among the three groups was examined by echocardiography.Results(1)The levels of serum sFas among the three groups were[ (0.54±0.20)ng/L in KD,(0.55±0.16)ng/L in IKD,and (0.24 ± 0.04) ng/L] in control group,respectively.The overall means of sFas in the KD and IKD groups were higher than the control group,and the differences were statistically significant( F=29.276,P＜0.05 ).(2)The levels of serum sFas among echocardiography abnormal and normal groups were[ (0.65±0.19) ng/L and (0.49±0.10)ng/L],respectively; and the difference between two groups were statistically significant ( t=3.139,P ＜ 0.05 ).ConclusionsThe expression levels of sFas in the peripheral serum of IKD children were increased,and there was a close association of overexpression of sFas with the cardiovascular damage in IKD children.

Objective To assess the clinical outcomes of glutamine supplementation in neonates.Methods The study was designed as a double-blind randomized controlled trial.Totally 100 infants were randomly divided into 5 groups with 20 infants in each group:control group:standard parenteral nutrition (PN);PNI group:PN supplemented with 0.3 g/ (kg·d) glutamine;enteral nutrition (EN) 1 group:EN supplemented with 0.3 g/ (kg·d) glutamine;PN2 group:PN supplemented with 0.3 g/ (kg·d) glutamine;and EN2 group:EN supplemented with 0.3 g/ (kg·d) glutamine,The primary endpoints were the time to establish full enteral nutrition [defined as receiving 120 ml/ (kg·d) enterally],episodes of gastric residuals,total duration of PN,and mortality.The second endpoints were weight gain and head circumference gain,liver function,renal function,days on ventilator,and length of hospitalization.Results Time to achieve full enteral nutrition,incidence of gastric residuals,duration of PN,weight gain (g/d) ,head circumference gain (cm/w),liver function,renal function,and length of hospitalization were not significantly different among all five groups.Days of mechanical ventilation were significantly decreased in PN1 group and PN2 group when compared with the control group (P ＜ 0.05).Intention-totreat analyses showed that,when compared with the control group,PN1 group:RR:1.053;95% CI:0.952-1.164;ENI group:RR:1.333,95% CI:1.035-1.717;PN2 group:RR:1.053,95% CI:0.952-1.164;EN2 group:RR:1.25,95% CI:1.004-1.556.Conclusions Glutamine supplementation may not be able to decrease the time to achieve full enteral nutrition,the incidence of gastric residuals,and the duration of PN.However,pareneral glutamine supplementation does reduce the days on ventilator in neonates.Also,parenteral glutamine supplementation has no obvious influence on mortality.

Objective To investigate the effect of phosphatidylinesitol-3 kinase/serine threonine kinase (PI3K/Akt) signaling pathway on expression of beta-site amyloid precursor protein cleaving enzyme-1 (BACE1) in the hippocampus neurons of rat brain. Methods Forty SD rats were randomly divided into 4 groups: blank control group, sham-operated group, insulin group and wortmannin group. Insulin or the specific inhibitor of PI3K, wortmannin was injected into hippocampus neurons to activate or inhibit the signaling pathway in insulin group or wortmannin group, respectively. Immunoprecipitation and Western blot were used to analyze the proteins levels of PI3K/Akt and BACE1. Results In insulin treatment group,among the proteins downstream of signaling pathway, expression of Akt increased (0. 952±0.060 vs 0.835±0.029,t=4.9150, P=0.0001), phospho-Akt set473 increased (0.800±0.075 vs 0.657± 0.025,t=4.5598, P=0.0002), phospho-GSK-3α decreased (0.604±0.062 vs 0.726±0.041, t= 3.5871, P=0.0018 ), and the expression of mature BACE1 and β-CTF significantly decreased. In wortmannin group, the expression of Akt and phospho-Akt ser473 were inhibited; phospho-GSK-3α increased ; mature BACEI (1.004±0.096) and β-CTF (1.031±0.048) increased (t=11.5980, P= 0.0000 and t =4.2194, P =0.0004, respectively). Conclusions PI3K/Akt signaling pathway might effect the expression of BACE1, in which impaired signaling pathway may cause the amyloid precursor protein to be easily processed by BACE1, and thus involves the pathology of Alzheimer' s disease.

OBJECTIVETo explore effects and action mechanism of warm moxibustion on regulation of blood lipids and anti-atherosclerosis.

METHODSForty-one male Japanese big-ear white rabbits were randomly divided into a blank group (10 rabbits), a model group (10 rabbits), a moxibustion group (10 rabbits) and a medication group (11 rabbits). Normal diet was applied in the blank group while high-cholesterol diet combined with injection of bovine serum albumin were applied in the rest groups to establish rabbit model of atherosclerosis. After establishment, the model group was not intervened and warm moxibustion was applied in the moxibustion group at "Zusan-li" (ST 36) and "Shenque" (CV 8), 10 min per acupoint per day for continuous 4 weeks. The medication group was treated with intragastric administration of lovastatin capsule (3.6 mg/kg) for continuous 4 weeks. The level of blood lipids, such as total cholesterol (TC), triglyceride (TG), and content of CD40 ligand (CD40L), soluble CD40 ligand (sCD40L) and expression of nuclear factor NF-kappaB were tested after 4 weeks.

RESULTSCompared with the model group, the moxibustion group and medication group could effectively reduce the contents of TC and low density lipoprotein (all P < 0.05), lower the level of sCD40L [(8.310 +/- 1.221) ng/mL in the model group, (7.097 +/- 0.846) ng/mL in the moxibustion group and (7.354 +/- 0.631) ng/mL in the medication group], reduce expression of CD40L [(0.235 +/- 0.179) mm2 in the model group, (0.072 +/- 0.079) mm2 in the moxibustion group and (0.039 +/- 0.015) mm2 in the medication group] and NF-kappaB [(0.145 +/- 0.052)mm2 in the model group, (0.052 +/- 0.012) mm2 in the moxibustion group and (0.036 +/- 0.013) mm2 in the medication group], indicating the significant difference (P < 0.05, P < 0.001). There was no statistical difference between the moxibustion group and medication group (all P > 0.05).

CONCLUSIONThe warm moxibustion has great effect on regulation of blood lipids and anti-atherosclerosis, in which lowering expression of CD40-CD40L could be one of possible mechanisms to take effect of anti-atherosclerosis.
