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

Objective To evaluate the effects of alendronate sodium on bone mineral density (BMD) in maintenance haemodialysis (MHD) patients with osteoporosis. Methods Twenty-eight MHD patients with osteoporosis diagnosed by dual energy X-ray absorptiometry were randomly divided into control group (n=15) and treatment group (n=13). Patients in treatment group were treated with oral 70 mg alendronate sodium once a week for 18 months. BMD of hip and lumbar spine was measured by dual energy X-ray absorptiometry at baseline and the end of the 6th, 12th and 18th month. Parathyroid hormone, calcium, phosphorous, alkaline phosphatase levels, blood routine, hepatic and renal function were assayed at baseline and the end of the 18th month, Kt/V was calculated, new bone fracture was recorded. Results The BMD, T-scores and Z-scores in the lumbar spine and specific regions of the hip were stable in the treatment group and obviously decreased in the control group (P<0.01). New bone fracture was found in 1 patient of the treatment group and 5 patients of the control group. The side-effect of alendronate sodium was epigastric discomfort in 1 cases. Conclusions Oral alendronate sodium appears to be well tolerated in MHD patients and keep the BMD stable in the lumbar spine and specific regions of the hip.

Aim To study relative bioavailablity of cefaclor effervescent tablets in healthy volunteers. Methods According to the crossover design, A volunteers were each orally given a single does of the 0.75 g cefaclor effervescent tablets and cefaclor capsules with an interval of 5 days between the two formulations.The plasma concentrations of the drug were determined by RP-HPLC.Pharmacokinetic parameters were obtained by ATPK programe,and calculated on the basis of open single compartment model.Results After a single oral dose, the peak levels in plasma averaged Cmax(31.27?5.81)?g?ml-1 and(30.56?5.25) ?g?ml-1 at (0.58?0.12)h and(0.73?0.17)h and AUC0～4(35.48?4.65) ?g?h?ml-1 and (35.89?2.90) ?g?h?ml-1 for tablet and capsule,respectively. Conclusion The result shows that two formulations are bioequivalence.
