Objective To explore methods of diagnostic and treatment for renal cortical abscess to reduce its misdiagnosis.Methods Eleven cases of renal cortical abscess diagnosed and treated at Beijing International Airport Hospital during 1991 to 2003 were reviewed and analyzed.Results Among the 11 patients with renal cortical abscess,diagnosis was established in nine(82%)before treatment,seven were cured by incision and drainage,one was cured by incision and drainage only after failure in percutaneous nephropuncture,and one was cured by intravenous injection of antibiotics.Two cases(18%)were misdiagnosed as renal cancer and radical nephrectomy were performed for them.Conclusions Diagnosis for renal cortical abscess should be based on combination of patients clinical manifestation,laboratory examinations and imaging findings.Incision and drainage is the choice of treatment for renal cortical abscess.

0.05). The average and maximal heart rates of subjects in bench stepping during exercise were higher than those in home stepping (P 0.05), however, the correlation between the direct calculation and home stepping was high (r=0.46, P 0.05).③The correlation between two step experiments for male students was high (r=0.73, P 0.05), however, the difference for female students was significant (P 0.05). CONCLUSION: Two indirect test protocols need further improvements, but home step is more appropriate for a large sample of constitution assessment by comparison of measurement efficiency and precision.

AIM:To investigate retinal vascular endothelial growth factor(VEGF)level and retinal cells apoptosis in the early stage of diabetic NOD mouse retina.METHODS:Animals were divided into the control group(non-diabetes mice)(2,4,6,8,12 weeks group,n=30)and diabetes group(2,4,6,8,12 weeks group,n=30).EUSA(Enzyme-Linked Immunosorbent Assay)was performed to detect VEGF level in both serum and retina.Transmission electron microscope method was used to examine retinal cell apoptosis.RESULTS:Compared with the control group,VEGF levels in serum and retina were increased significantly in the NOD group(12 weeks:4.9±0.4μg/g versus 0.19±0.1μg/g in serum sample,P ＜ 0.01;165.0±9.0μg/g versus 18.0±4.0μg/g in retinal sample,P＜0.01).There exists a positive correlation between serum VEGF and retinal VEGF levels in the early diabetic NOD mice(γ=0.9902,P=0.001).The number of the cells apoptosis in the ganglion significantly in the NOD group(P＜0.01).CONCLUSION:The high VEGF expression may be contributed to increase retinal cells apoptosis.Many factors associated with retinal VEGF expression might involve in the early diabetes stage.

Diabetes is a complex and heterogeneous disorder presently affecting more than 100 million people worldwide and causing serious socio-economic problems. Spontaneous rodent models of diabetes mellitus have proved invaluable in understanding the pathogenesis, complications, and genetic or environmental influences that increase the risks of diabetes. We have reviewed here in the development and characterization of spontaneous rodent models that displayed most features commonly associated with diabetic retinopathy.

Objective To investigate the apoptotic effects of hypertrophic scar fibroblast (HSF) induced by HMME-PDT.Methods Fibroblasts were cultured from nontreated hypertrophic scars,and cells at passages 4-6 were used for the experiments (photosensitizer dose 4 μg/ml,λ630 nm,pow er density 10 mw/cm2,energy fluence 2.5 J/cm2).Morphological and biochemical changes in fibroblasts were assessed by Hoechst 33258 staining and fluorescence microscopy.The rate of apoptotic or necrotic cells was detected by flow cytometry (FCM) through double staining of Annexin V -FITC and popodium iodide (PI),respectively.Results Marked morphological features of cell apoptosis were viewed under the fluorescent microscope through Hoechst 33258 staining.The analysis of FCM indica ted that the apoptotic rate was significantly increased after HMME PDT [(34.82 ± I.42) ％ vs (3.12±0.28) ％,P＜0.05],and apoptotic rate was higher than necrosis rate [(14.65±1.02) ％ vs (34.82±1.42) ％,P＜0.05].Conclusions Low level exposure to 630 nm PDT mediated by HMME appears to induce fibroblast apoptosis.

Objective To explore the traditional Chinese and western medication principle of treating epilepsy based on text mining, and provide a reference for clinical use. Methods Based on the literature data of treatment of epilepsy collected in CBM database, we explored the medication principle of both traditional Chinese medicine and western medicine for treating epilepsy by frequency statistical data based on sensitive keywords hierarchical algorithm, retro-read and manually noise reduction. These laws displayed by the frequency of one-dimensional and two-dimensional network diagram. Results Commonly used drugs in western medicine treatment for epilepsy are phenobarbital, phenytoin, valproate, carbamazepine and diazepam. Traditional Chinese medicine commonly used are Angongniuhuang Pill, Qingkailing Injection, Wumei Pill, Tongxinluo Capsule, Compound Danshen Dripping Pill, Xuefuzhuyu Capsule, etc. When traditional Chinese medicine and western medicine are combined used, the most commonly used traditional Chinese medicine are Angongniuhuang Pill, Qingkailing Injection and Compound Danshen Tablet, western medicine are phenobarbital, valproate, carbamazepine and diazepam. Common syndromes are yin deficiency of liver and kidney, deficiency of kidney yin, heart tangled by sputum, deficiency of yin, heart disturbance by sputum and fire. Conclusion Text mining technology can be used for summary of medication principle of treating epilepsy and of epilepsy syndrome, thus provide useful exploration and reference for clinical diagnosis and treatment.
