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.

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.

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 effect of emodin on endoplasmic reticulum (ER) stress of pancreatic acinar AR42J cells.

METHODRat pancreatic acinar AR42J cells were cultured in 6-well plates, and divided into the normal control group, the model group (with the final concentration at 1 x 10(-7) mol · L(-1) for cerulean and lipopolysaccharide at 10 mg · L(-1)) and the emodin group (10, 20, 40 μmol · L(-1)). Cells in each group were cultured in three multiple pores for 24 h, and their supernate was removed after cell attachment. The normal control group was added with haploids, the model group was added with the modeling liquid for haploids, and the treatment groups were added with different concentrations of emodin at 15-20 min before the modeling liquid. The cells were continuously cultured for 3 h under 37 °C and 5% CO2. Their intracellular protease and lipase expressions were detected with kits. The cellular morphology was observed under optical microscope. The level of calcium in endoplasmic reticulum was measured under laser confocal microscopy. Western blot assay were used to determine the protein expression of ER-related signaling molecules.

RESULTEmodin could significantly inhibit levels of amylase, lipase and intracellular calcium and ER.

CONCLUSIONEmodin could reduce pancreatic acinar cell injury induced by the combination of cerulean and lipopolysaccharide. Its action mechanism is correlated with the inhibition of intracellular calcium overload and ER stress.

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.

The purpose of this study was to evaluate the impact of callus induction and culture conditions on secondary metabolic diversity of the callus cell lines of traditional Chinese medicinal plant Glycyrrhiza sp. (Glycyrrhiza) by combined chemical analysis and HPLC fingerprint. These callus induction conditions included two Glycyrrhiza species, two types of explants, light and dark conditions, and two combinations of hormones. The evaluation was firstly based on the contents of total flavonoids in the callus by chemical analysis and one way ANOVA. The content of total flavonoids in callus was significantly (P < 0.05) influenced by Glycyrrhiza species, light condition, and the combination of hormones. The callus was further evaluated using diversity factor based on the comparison of HPLC fingerprints of these callus cell lines. Diversity factor varies significantly for calli induced under different conditions, with the highest being at 0.45 under light condition and combination of hormones. These results provide important knowledge for the selection of suitable callus cell lines for the production of pharmacologically important secondary metabolites or bioactive fractions by in vitro culture of Glycyrrhiza sp.
