Cisplatin is an anti-tumor drug which is widely used for the treatment of various solid tumors. Unfortunately, seriousside-effects have affected patients, such as hearing loss. Up to now, there is no clear and effective measure to protect the cisplatin-induced ototoxicity in the clinical use of cisplatin studies indicated that autophagy may be involved in the whole process of cisplatin-induced hearing loss. In this review, the relationship between cisplatin ototoxicity and autophagy was reviewed. It is hoped that this study can provide reference for further study of cisplatin ototoxicity and intervention of autophagy with autophagy activator or inhibitor.

AIM:To analyze the killing efficiency of six kinds of contact lens solutions and solutions with arilin on free living Acanthamoeba culturedin vitroMETHODS:Six kinds of contact lens solutions were added into 96-well microtiter plates,respectively,with each care solutions used 48 holes of them.Suspension of Acanthamoeba were added into 24 of these holes.and arilin gutta and suspension of Acanthamoeba were added into the other 24 holes.After standing in room ternperature for 8 hours,the morphologic change and quantity of the remnant Acanthamoeba were observed under the jnverted microscope.The remnant Acanthamoeba were cultivanted in peptone-yeast extract-glucose (PYG)-culture medium for 5 days.Their variation of appearance,activity and reproductive activity were observed.RESULTS:In the six experimental groups using contact lens solutions only.the detection rate of Acanthamoeba of were 0%,80.3%,29.1%,41.7%,62.5% and 79.2%,respectively.After arilin was added,the detection rate of Acanthamoeba of the six groups were 0%,0%,4.2%,8.3%,16.7% and 16.7%,respectively.From group 3 to group 6,after arilin was added,the differences of the killing efficiency of contact lens solutions have statistical significance(X2=3.75,7.11,10.54 and 18.78;P＜0.05).Cultivation of the remnant Acanthamoeba showed a reduction in the activity and proliferative ability.CONCLUSION:The killing efficiency of some contact lens solutions on free-living Acanthamoeba were not satisfying.Arilin can improve the killing efficiency of contact lens solutions.

AIM: To compare the adherent ability of Acanthamoeba to three kinds of contact lens (CL) and survey the effect to remove the Acanthamoeba from the surface of contact lens after blowing with stroke-physiological saline solution (SPSS) repeatedly.METHODS: Three kinds of contact lens were chosen in this experiment, including: rigid gas permeable (RGP) contact lens, soft contact lens (SCL) and colored contact lens. They were co-cultivated with Acanthamoeba suspension for 16 hours. Then the number of Acanthamoeba adhered on CL was compared. Comparison was also made between different zones of colored CL. We also compared the number of Acanthamoeba adhered on CL in three groups after blowing with SPSS.RESULTS: The number of Acanthamoeba adhered to colored CL was more than RGP group and SCL group (P<0.05). The differences between RGP group and SCL group had no statistical significance (P>0.05). In colored CL group, the number of Acanthamoeba adhered to the colored zone was more than the Uncolored zone (P<0.01). In all the three groups, after blowing with SPSS, there was statistically significant decrease of the number of Acanthamoeba adhered to CL (P<0.01).CONCLUSION: Compared with RGP group and SCL group, the colored contact lens was more vulnerable to be adhered by Acanthamoeba. After being blown by SPSS repeatedly, the effect to eliminate Acanthamoeba has been improved greatly.

Metal sulfides are chemically attacked by Fe~ 3+ and H~+, resulting in the formation of elemental sulfur via polysulfides or thiosulfate pathway. Elemental sulfur may aggregate and even form a layer on the metal sulfide surface, which will inhibit leaching metals from the sulfides minerals. Elimination of inert elemental sulfur in a typical acidic environment can exclusively be by way of oxidation of acidophilic sulfur-oxidizing bacteria, such a way includes the attachment, transport and oxidation process of elemental sulfur by acidophilic sulfur-oxidizing bacteria. On the basis of analysis on the pertinent researches, the molecular mechanism of sulfur elimination by the acidophilic bacteria is far away from elucidated, and to attain that target, there are still much work to be done for elucidating the molecular mechanism on the attachment, transport and oxidation process of elemental sulfur by the acidophilic sulfur-oxidizing bacteria.

The key point of study on CO2 removal by microalgae cultured in a photobioreactor is to improve CO2 removal capability. In this paper, a model of air-lift photobioreactor was developed by combination of conditions including the velocity of flow, the degree of mixing, the gas-liquid mass transfer and the rate of photosynthesis, and two corresponding simplified methods, such as time discretization and lumped parameters were put forward. Using a method of lumped parameters, the model for simulation of time course of DO, pH in the column air-lift photobioreactor and prediction of CO2, O2 concentrations in the outlet gas under different CO2 concentration in the aeration gas was thoroughly discussed. Experimental data were also used to verify the model which could potentially be applied to rational design of the photobioreactor, high-density culture of microalgae and efficient removal of CO2.

Reverse transcriptase-PCR experiments suggest that the two clusters of genes potentially involved in the oxidation of reduced sulfur compounds are organized as operons in strain of the acidophilic, chemolithoautotrophic bacterium Acidithiobacillus ferrooxidans ATCC 23270, the two clusters of genes including such the ORF of putative sulfate-thiosulfate-molybdate binding proteins, the ORF of putative thiosulfate: quinone oxidoreductase and the ORF of the rhodanese-like protein (P21). Bioinformatic analyses have predicted the possible promoters sequences and the possible +1 start site of transcription for the doxDA operons.

OBJECTIVETo observe the therapeutic efficacy and safety of gonadotropin-releasing hormone agonist (GnRHa) combined Wenshen Xiaozheng Decoction (WXD) in auxiliary treating endometriosis after laparoscopy.

METHODSOne hundred and thirty-four endometriosis patients with confirmative pathological diagnosis were assigned to three groups depending on whether they would receive adjuvant therapy or Chinese medicine treatment, i.e., the control group, the observation 1 group, and the observation 2 group. The 22 patients in the control group received no adjuvant therapy after laparoscopy. The 42 patients in the observation 1 group were treated with GnRHa 3.6 mg by subcutaneous injection starting from the 1st day to the 5th day of menstruation, once per 28 days. The 70 patients in the observation 2 group were treated with GnRHa 3.6 mg by subcutaneous injection in combination with WXD starting from the 1st day to the 5th day of menstruation, once per 28 days. They also took WXD for 7 doses, one cycle per every 28 days. The treatment lasted for three to six months. Serum levels of estradiol (E2), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and cancer antigen 125 (CA125), as well as clinical efficacy, and adverse drug reactions were observed before and after treatment.

RESULTSThere was statistical difference in serum levels of E2, FSH, or LH between the control group and the observation 1 and 2 groups (P < 0.05). There was no statistical difference in serum levels of E2, FSH, or LH between the observation 1 group and the observation 2 group (P > 0.05). There was statistical difference in the clinical efficiency among the 3 groups (P < 0.05). There was statistical difference in the pre-post difference of CA125 levels among the three groups (P < 0.01). Compared with the control group, there was no statistical difference in the pre-post difference of CA125 levels between the observation 1 group and the observation 2 group (P > 0.05). No obvious adverse reaction occurred during the treatment.

CONCLUSIONSGnRHa combined WXD showed confirmative clinical efficacy in treating endometriosis after laparoscopy. It also could lower serum levels of E2, FSH, and LH levels. So it was an ideal solution for treatment of endometriosis.

Aim To study the effect of simvastatin on the production of reactive oxygen species ( ROS ) and the secretion of interleukin-1 beta ( IL-1β) in oxidized low density lipoprotein ( oxLDL )-induced macropha-ges. Methods After the murine macrophage J774A. 1 was treated with 0,50,100,200 mg·L-1 oxLDL, the contents of aggregated lipid in macrophages were ob-served and determined by oil red O staining. Then, the oxLDL-primed macrophages were treated with 0 . 5 ,1 . 0μmol·L-1 simvastatin, the production of ROS was de-termined by flow cytometry and the expressions of pro-caspase-1 , cleaved caspase-1 and mature IL-1βon pro-tein level were determined by Western blot. Results The oil red O staining results showed that oxLDL could induce obvious lipid aggregation in macrophages, and reached the saturation point with 100 mg·L-1 concen-tration. Flow cytometry results indicated that oxLDL could induce the production of ROS in macrophages, up to 167% ± 0. 47%, and ROS level decreased to 139% ± 0. 97% in a dose-dependent manner after treatment with simvastatin. Western blot indicated that simvastatin could inhibit the expression of cleaved caspase-1 and mature IL-1β in macrophages triggered by oxLDL;compared with oxLDL group, the expression of cleaved caspase-1 and mature IL-1β decreased in simvastatin treated group, and all results had statistical significance ( P<0. 05 ) . Conclusion In the lipid ag-gregation model of macrophages induced by oxLDL, simvastatin can inhibit the production of ROS, caspase-1 activation, and secretion of IL-1β in macrophages.
