OBJECTIVE To observe and compare the cytotoxicity induced by andrographolide (AD)and its water soluble derivatives:andrographolide sodium bisulfite(ASB),active pharmaceutical ingredients of Chuanhuning and Yanhuning on human renal tubular epithelial cells (HK-2),and to explore the ASB-induced endoplasmic reticulum stress(ERS)mechanism. METHODS HK-2 cells were treated with the above four drugs respectively. The survival rate was examined by methyl thiazolyltetrazolium (MTT) assay and 50% inhibitory concentration (IC50) was calculated. In ASB treated group, Hoechst33342 staining and flow cytometry analysis were used to determine cell apoptosis, intracellular superoxide dismutase(SOD)activity and malondialdehyde(MDA)content were examined, and the protein expressions of binding immunoglobulin protein (Bip),C/EBP-homologous protein (CHOP)and cysteine-containing aspartate-specific protease 4(caspase 4)were detected by Western blotting. RESULTS The four drugs inhibited HK-2 cell growth in a time-dependent and concentration-dependent manner. At 24 h,the IC50 of AD (30.6 μmol · L- 1) was lower than that of others. Active pharmaceutical ingredients of Chuanhuning and Yanhuning (16.2 and 15.6 mmol · L- 1) were very close,ASB was 29.4 mmol · L-1. ASB(0,15,30 and 60 mmol · L-1)increased the apoptotic rate and caused the decrease in SOD activity and the increase in MDA content in a dose-dependent manner. Compared with control group,the protein expression of CHOP increased (P<0.01) at 8 h with ASB (30 and 60 mmol · L-1)treatment,Bip and caspase 4 had no significant change. In addition,at 24 h, ASB(60 mmol·L-1) decreased the expression of Bip(P<0.05),ASB(30 and 60 mmol·L-1)promoted the expression of CHOP(P<0.01),and the protein expression of activated caspase 4 increased in a concentration-dependent manner(P<0.01). CONCLUSION AD and its water soluble derivatives have a toxic effect on HK-2 cells. CHOP and caspase 4 pathway related to ERS is involved in ASB-induced apoptosis.

Objective To investigate the infection situation of L-form bacteria in urinary calculi from the patients with urolithia-sis in a hospital to provide a scientific basis for postoperative anti-infection and prevention of urinary stone recurrence.Methods The calculi samples in 265 cases of urinary calculi from October to December 2015 were collected and performed the culture of com-mon bacteria and L-form bacteria respectively.Culture of common bacteria and bacterial L-forms.Results Among 265 cases of uri-nary calculi ,8 cases(3% ,8/265) were L-form Bacterial combined with common bacterial infection ,only 7 cases(2.6% ,7/265) were L-form bacterial infection ,80 cases (30.0% ,80/265) were common bacterial infection.15 strains of L-form bacteria were detected and 96 strains of common bacteria were detected.The drug resistance of L-form bacteria was significantly increased compared with common bacteria.Conclusion The positive rate of L-form bacteria culture of urinary calculi is lower than other domestic reports. Adding hypertonic medium for conducting L-form bacterial isolation and culture in the patients with urinary tract infection can re-duce the false negative.

Aim To study the effect of novel AChE inhibitors, 2-phenoxy-indan-1-one derivatives (YKY-1~7), against glutamatic acid-induced neurotoxicity in PC12 cells and on learning & memory impairment in dementia model mice induced by A?25~35 icv Methods The PC12 cells were preincubated with different concentrations of YKY-1~7 for 24 h and subsequently treated by glutamatic acid, at the high concentration of 2 mmol?L-1 for 15 min to induce cytotoxicity. The cell viability was assessed with MTT method.. Dementia model mice were made by intracerebroventricular injection (icv) of aggregated A?25~35. From the next day, the model mice were administered YKY-7 (2.5, 5, 10 mg?kg-1, ig) for 10 consecutive days and sham control mice or A? model control mice received daily ig saline. After the final treatment, the passive avoidance learning was tested, regional cerebral blood flow at cerebral cortex was assessed, and the activity of AChE in the cerebral cortex, hippocampus and blood serum were determined. Results Six out of the seven YKY compounds appeared to be effective against glutamatic acid-induced neurotoxicity in PC12 cells, with YKY-7 demonstrating the most activity. YKY-7 significantly ameliorated the learning and memory ability in dementia model mice induced by A?25-35 icv, slightly and selectively inhibited the cortical and hippocampal AChE, and gently increased the blood flow at cerebral cortex. Conclusion Some of 2-phenoxy-indan-1-one derivatives reported here have protective effects against glutamatic acid induced neurotoxicity in PC12 cells, and improve the learning and memory impairment induced by A?25-35, which may be partly attributable to its selective inhibition of AChE activity in the cerebral cortex and hippocampus.
