Objective To explore whether the glomerular podocytes can be damaged by aristolochic acid. Methods Thirty-two male SD rats were equally divided into the following 2 groups:model group in which the rats received the extract of Aristolochia manshuriensis Kom (AmK) by gavage; control group only received tap water by gavage.24 h urinary protein excretion was measured at the end of the 1st and 4th week,and SDS-PAGE gel electrophoresis was performed to detect the protein in urine.At the end of the 4th week,all the rats were sacrificed and the glomeruli were isolated by laser capture microdissection technique.The mRNA expression of nephrin,podocin,CDA2P,podocalyxin and podoplanin in isolated glomeruli was determined by RT-PCR,and the average width of glomerular foot process was measured by electron microscopy and image analysis. Results At the end of the 4th week,24 h urinary protein excretion in the model group was significantly higher than that in the control group (P＜0.01) and the urinary albumin content in model group was also obviously increased.The average width of glomerular foot process in the model group was significantly larger than that in control group (P＜0.01).The mRNA expressions of nephrin,podocin,CDA2P,podocalyxin and podoplanin in glomeruli were significantly down-regulated in the model group compared with the control group,which decreased by 34％,62％,56％,50％(P＜0.01) and 27％ (P＜0.05),respectively. Conclusions Aristolochic acid can damage the glomerular podocytes,resulting in the down-regulation of nephrin,podocin,CD2AP,podoplanin and podocalyxin mRNA expression, the segmental widening of foot process, and increased urinary protein excretion.

?AlM: To investigate theprotective effect of melatonin against hydrogen peroxide ( H2 O2 )-induced oxidative damage to human lens epithelial cells.
?METHODS: Sub-culture human lens epithelial cells preprocessed with different concentrations of melatonin for 12h and then 100 μmol/L H2 O2 for 24h. The impact of melatonin on H2 O2-induced lens epithelial cell viability was detected by MTT assay, rate of apoptosis was detected by flow cytometry instrument and activity of apoptosis-related factors, Caspase-3 and Caspase-9, were detected by colorimetric method.
?RESULTS: MTT assay showed that melatonin had no effect on the activity of lens epithelial cells, and the drug can inhibit the decrease of H2 O2-induced cell activity, as well as flow cytometry showed that melatonin can inhibit H2 O2-induced apoptosis. ln addition, melatonin can also reduce H2 O2-induced Caspase-3 and Caspase-9 activity in lens epithelial cells, and their activity decreased with effect of melatonin along with extending time.
?CONCLUSlON: Melatonin can obviously inhibit H2 O2 -induced apoptosis of human lens epithelial cells, which provide reliable experimental basis for drug on treatment of cataract.

Objective To examine whether aldosterone contribute to obesity related glomerular disease. Methods C57BL/6J mice were randomly divided into three groups: a control group (low?fat?diet, n=10), a model group (high?fat?diet, n=10) and a intervention group (high?fat?diet, n=12). After 8 weeks intervention group were treated with a mineralocorticoid receptor antagonist, spirolactone (SPL).The physicochemical indexes and the renal pathology of the three groups were all detected. The mRNA and protein expressions of podocyte marker protein were determined by real?time PCR and Western blotting, respectively. Results Compared with the control group, body weight, kidney weight, Lee ’s index, fat index, blood cholesterol, blood triglyceride, creatinine clearance rate, urinary protein excretion, glomerular average diameter, glomerular foot process average width were significantly up ? regulated (P<0.05); The mRNA and protein expression of nephrin, podocin, podoplanin and podocalyxin were significantly down?regulated in model group (P<0.05). Meanwhile, these changes were attenuated by SPL. Conclusion Aldosterone can participate in the process of obesity? related renal injury, and these can be attenuated by mineralocorticoid receptor antagonist, spirolactone. This gives us preliminary clues to treat ORG.

Objective To evaluate MR diagnostic value of neurovascular compression in patients with hemifacial spasm(HFS). Methods MRI and MRA manifestations and operative results of eighteen patients with HFS were reviewed retrospectively.Results (1)The roots of the facial nerve involved sides were compressed by vessel in all cases.(2)There was statistical correlation between the vascular compression of the root exit zone(REZ)of facial nerves and the symptoms of HFS(P

Objective To study the clinical characteristics and curative effects of pancreatic cystade- nocarcinoma in order to improve its diagnostic and therapeutic accuracy.Methods A retrospective analysis was done on the clinical materials of 13 cases of pancreatic cystadenocarcinoma hospitalized in Shanxi Cancer Hospital from 1990 to 2006.Results The preoperative diagnosis were as follows:pancreatic cystadenocarci- noma 6 cases,pancreatic cystadenoma 2 cases,pancreatic cancer 1 case,pancreatic pseudocyst 4 cases.The misdiagnosis rate was 53.8 %.Surgical operation was done on the 13 cases,and 10 of them were treated by radical operation.A 5-year follow-up was done on 6 still alive cases,and 1 of them lived over 11 years.3 cases were treated by palliative operation,and all of them died within 3 years.Conclusion Since there is no specific clinical manifestations of pancreatic cystadenocarcinoma,it is very difficult to get an accurate preop- erative diagnosis.Radical operation is the most effective therapeutic methods.

The clinical characteristics of patients who presented in poor clinical grade due to ruptured middle cerebral artery aneurysms (MCAAs) associated with large sylvian hematomas (SylH) were analyzed and an ingenious designed prophylactic hinged craniectomy was introduced. Twenty-eight patients were graded into Hunt-Hess grades IV-V and emergency standard micro-neurosurgeries (aneurysm clipping, hematoma evacuation and prophylactic hinged craniectomy) were performed, and their clinical data were retrospectively analyzed. 46.43% of the patients reached encouraged favorable outcomes on discharge. The favorable outcome group and the poor outcome group significantly differed in terms of patients' anisocoria, Hunt-Hess grade before surgery, extent of the midline shift and time to the surgery after bleeding (P<0.05). There were no significant differences in age, sex, volume and location of the hematoma, size of aneurysm between the favorable and poor groups (P>0.05). However, ingenious designed prophylactic hinged craniectomy efficiently reduced the patients' intracranial pressure (ICP) after surgery. It was suggested that preoperative conditions such as Hunt-Hess grading, extent of the midline shift and the occurrence of cerebral hernia affect the prognosis of patients, but time to the surgery after bleeding and prophylactic hinged craniectomy are of significant importance for optimizing the prognosis of MCAA patients presenting with large SylH.

?AIM:To evaluate the objective visual quality of patients who underwent corneal cross-linking for the keratoconus using double-pass analysis system.? METHODS: Advanced keratoconus patients who underwent UV - riboflavin corneal cross - linking from January to July 2015 were included. The outcomes of their objective scattering index ( OSI ) , predicted visual acuity ( VA ) , the cut - off frequency of modulation transfer function ( MTF cut- off ) , the Strehl ratio ( SR ) were compared before and 6mo after corneal cross-linking.?RESULTS: A total of 13 patients ( 16 eyes ) were included. There was no statistically significant difference between pre- and 6mo postoperative data in uncorrected visual acuity, best corrected visual acuity, refractions and mean value of Sim-k (P>0. 05). Non-invasive average tear film break up time ( NIAvg-BUT ) detected by the Sirius system decreased after corneal cross-linking ( P<0. 05 ) . Using double - pass analysis system, no statistically significant change was found in MTF cut off, Strehl Ratio, OSI before and after treatment(P>0. 05). Tear Film Analysis Mean OSI increased at 6mo postoperatively (P<0. 05).? CONCLUSION: The subjective visual quality isn’t effected by corneal cross-linking. The tear stabilities of patients are influenced by these operations at 6mo postoperatively. More observations on long-term effect are needed to be taken in the future.
