Objective：To study the clinical and pathologic features of patients with lupus nephritis (LN) whose myeloperoxidase anti-neutrophil cytoplasmic antibody (MPO-ANCA) were positive. Methods：The clinical and pathological features were analyzed in 18 patients with LN whose MPO-ANCA were positive. And the data of patients with different clinical outcomes were compared. Results：（1）The hematological abnormalities, hypertension and serositis in these patients were more common than general ones with LN. （2）Proteinuria and hematuria were common, the morbidities of gross hematuria and renal failure in these patients were higher than general ones with LN.（3）Various autoantibodies were positive in these patients.（4）Segmental necrosis crescentic nephritis accompanied by density of immunocomplex in glomeruli and vasculitis in intestitium were common.（5）The morbidity of ESRF and mortality of these patients were similar to general ones with LN. The morbidity of tubular atrophy in those with poor prognosis was significantly higher than those survived. Conclusion：The patients with LN whose MPO-ANCA are positive have some difference from those with negative MPO-ANCA, but positive MPO-ANCA is not directly related to the prognosis.

Phosphate-dissolving microorganisms are widely distributed in soil, rhizosphere and other ecological environment. Understanding the characteristics of these microorganisms in solubilizing phosphates is helpful to apply them in improving P use efficiency. The obtained results indicated that the fungi had much higher capacity to dissolve the rock than the bacteria. Existence of Fe, Al, Mg and Na in the culture media reduced the rock solubilization by the bacteria, but increased the solubilization of the fungi. The higher content of the rock in the media, the lower capacity of the rock phosphate solubilization was found. The capacity was also significantly reduced if the concentration of C material in the media was higher than 3%. It was also found that the microorganisms destroyed the rock structure. The P was more easily released from the rock at further incubation. In conclusion, there is some potential to utilize the microorganisms to activate the rock phosphate.

Objective To characterize the language development and articulation in children with different types of cerebral palsy. Methods The data from 76 children with cerebral palsy who underwent standardized tests of speech and language were analyzed. The incidence and abnormal pattern were compared between groups. ResultsLanguage delay and/or dysarthria were noted in 73.1% of these subjects. Children with diplegia developed similar levels both in comprehension and verbal expression, whereas those with tetraplegia and athetoid developed poorer verbal expression. The incidence of language delay in children with diplegia, tetraplegia and athetoid were 45.95%, 90% and 64.7%, respectively. Dysarthria was found in all the children with tetraplegia, athetoid and ataxia, but only 48.65% of those with diplegia. Conclusion Language disorders were common in children with cerebral palsy, especially those with athetoid and tetraplegia.

Objective To assess the antimicrobial actitivity of econazole nitrate in comparison with other six antibacterial drugs. Methods The minimal inhibitory concentrations (MICs) of econazole nitrate (Eco), neomycin (Neo), erythromycin (E), penicillin (P), cefotaxime sodium (Cef), ciprofloxacin (Cip) and amikacin (An) to 222 strains of Staphylococcus spp isolated from the lesions of patients with eczema and atopic dermatitis were determined by using the broth dilution method. Results MIC50 values of Eco were similar to Neo, Cip, An and Cef, and lower than those of P and E on methicillin-sensitive Staphylococcus aureus (MSSA); significantly lower than those of the other six antibacterial drugs on methicillin-resistant Staphylococcus aureus (MRSA); similar to An, Cip and P, and lower than those of Neo, Cef and E on methicillin-sensitive and coagulase-negative Staphylococcus (MSCNS); and similar to An, Cip P or Neo, and lower than Cef and E on methicillin-resistant and coagulase negative Staphylococus (MRCNS). Based on the NCCLS standards, the resistance rates of Cip, P and E were very high to either Staphylococcus areus or coagulase-negative Staphylococcus (CNS). The resistance rates of An and Cef of were lower to MSSA, but higher than 50% to MRSA. MIC90 value of Eco was similar to its MIC50, and lower than the MIC value reported in the literature. The MIC90 value of neomycin was muich higher than the MIC50 value of econazole. Conclusion Econazole nitrate has antibacterial activity to both Staphylococcus areus and CNS. MIC90 value of Eco is similar to its MIC50, and no resistance to Eco was found.

Objective To assess mucin gene expression in Barrett's esophagus.Methods Mucin core protein-MUC1,MUC2,MUC3,MUCSAC and MUC6 were detected by immunohistochemistry.The re- lationship between mucin expression and magnification-endoscopic characteristics,pathohistologic epithelial types of Barrett's esophagus was analyzed.Results Mild expression of MUC1 was predominantly found in the superficial epithelium of both gastric and specialised intestinal metaplasia.In a small number of specimens, mild expression of MUC1 was also noted in glands.Strong MUC2 expression was noted only in the goblet cells in Barrett's oesophagus.MUC3 was expressed in the superficial columnar cells of specialized intestinal metaplasia with or without globlet cells but not in gastric metaplasia of the oesophagus.In some specimens MUC3 was expressed in the vacuolus of the globlet cells and the lumen of gland.Strong staining of MUCSAC was noted in the columnar epithelium of both gastric metaplasia and specialized intestinal metaplasia in Barrett's oesophagus,as well as expressed in the cytoplasm and vacuolus of the globlet cells in some speci- mens.Expression of MUC6 protein was detected at the basement of the crypts in gastric metaplasia and spe- cialised Barrett's glands.Expression of MUC2 and MUC3 protein was found much higher in villous or irregu- lar pit pattern than that in dot or rod pit pattern(P

AIM:To assess changes of tear film function in patients after pterygium excision combined with amniotic membrane transplantation.
METHODS:Totally 126 patients with pterygium excision with amniotic membrane transplantation from January 2011 to November 2013 were entered in the study. The tear breakup time ( BUT) , the Schirmer I test ( SⅠt) and tear ferning test ( TFT ) were elevated in the patients before and after pterygium excision combined with amniotic membrane transplantation. The examnation times were 1d before surgey, 1wk, 1, 2mo after surgery. Operation eyes were studied group, while opposite healthy eyes as control group.
RESULTS: Compared with the control group, BUT and TFT were significantly different in the eyes with pterygium (P<0. 05); However, no obvious difference was detected in the results of SⅠt (P>0. 05). The results of BUT and TFT at 1mo after surgery in study group were significantly better than 1wk (P<0. 05), while no significant difference compared with 2mo (P>0. 05); The tear film stability in the study group at 1wk after surgery was still inferior to the control group (P<0. 05) and there was no significant difference at 1, 2mo after surgery (P all>0. 05). SⅠt results did not differ between the different examination times(P>0. 05).
CONCLUSION:Tear film stability was broken in the eyes with pterygium. Pterygium excision combined with amniotic membrane transplantation can obviously restore the tear film function into normal state, and the tear film function could reach steady-state 1mo after surgery.

Objective To investigate the effect of acupuncture at Zusanli, Sanyinjiao and Danzhong on mammary estrogen receptor (ER) and progesterone receptor (PR) expressions in rats with dimethylbenzanthracine (DMBA)-induced mammary cancer. Methods One hundred and twenty female SD rats aged 6-8 weeks were randomized into a model group of 60 rats and a blank group of 30 rats. The model group received an oral gavage of DMBA for model making. The blank group received an oral gavage of equal volume of sesame oil. At 15 weeks after model making, the model group of rats was randomized into treatment and control groups. The treatment group received acupuncture at Zusanli, Sanyinjiao and Danzhong, and the control and blank groups, only the same grasp and release. After the completion of acupuncture treatment (twenty-seventh week), abdominal venous blood was taken and serum tumor markers were determined by electrochemiluminescence immunoassay. Tumor masses were counted and their shapes were recorded. The mass was taken and its height, maximum diameter and vertical diameter were measured using a 1 mm precision vernier caliper. Pathological changes in tumor tissues, and ER and PR positive areas and mean optical densities were observed under an Olympus optical microscope.Results There were statistically significant post-treatment differences in the average number and volume of mammary tumors between the treatment group and the control or blank group (P<0.01,P<0.05) and between the control and blank groups (P<0.01). There were statistically significant post-treatment differences in the concentrations of various tumor markers (CA724, CA125, CA199, AEP, CA15-3, CEA and CA50) between the treatment or control group and the blank group (P<0.01,P<0.05) and between the control and blank groups (P<0.01). There was a statistically significant post-treatment difference in CA15-3 concentration between the treatment and control groups (P<0.01). There were statistically significant post-treatment differences in ER and PR positive areas and mean optical densities between the treatment group and the control or blank group (P<0.01) and between the control and blank groups (P<0.01).Conclusions Acupuncture can reduce the occurrence of rat DMBA-induced mammary tumor (including the number and volumes of the tumors). The mechanism of its action may be related to decreasing the concentrations of tumor markers CA724, CA125, CA199, CA15-3, AEP, CEA and CA50 and especially to decreasing CA15-3 concentration, and ER and PR positive areas and mean optical densities.
