Objective To investigate the effects of methamphetamine (Meth) on the outward K+ currents and elucidate the role of outward K+ channels in Meth induced hippocampal neuron damage.Methods Hippocampal neurons were harvest from 18-day-old embryonic rats and were divided into two groups:the control group and the Meth treated group.Both of 4-AP and TEA sensitive K+ currents were recorded after the treatment of Meth by performing the whole cell patch clamp.Furthermore,the MTT and TUNEL assays were performed to evaluate the effects of K+ channel on hippocampal neuron damage mediated by Meth.For statistical comparison,One-way ANOVA and LSD multiple comparison test or t-test was used.P-value ＜ 0.05 was considered to be statistically significant.Results The density of 4-AP sensitive K+ channel currents in Meth treated group [(120.1 ± 19.6) pA/pF,n =7] were significantly increased when compared with control group [(87.4 ± 12.5) pA/pF,n =10,P ＜0.01] and the increments of the currents induced by Meth was dose dependent.The MTT data showed that the cell viability was obviously decreased in Meth treated group (48.72 ± 4.38) ％ relative to the control group (100.07 ± 3.36) ％.Moreover,application of K+ channel antagonist,4-AP (61.39 ± 3.15)％,and the high K+ solution (78.25 ± 9.42) ％ substantially enhanced the cell viability.The TUNEL assay showed there were protective effects of 4-AP and the high K+ solution against neuron damage observed during cells exposed to Meth.Conclusions The increments of 4-AP sensitive K+ channel currents induced by Meth might be involved in hippocampal neuron damage.

Objective To explore the effect of SZ-685C on rat pituitary adenoma GH3 cell line.Methods MTT method evaluated its effect of proliferation and inhibitory concentration 50 (IC5o) on GH3 cells,after treated by 0,2.5,5.0,7.5,10.0,12.5,15.0,17.5,20.0 and 30.0 μmol/L SZ-685C for 48 h,GH3 cells were changed to complete medium for 12 d,crystal violet staining was used to investigate colony formation; microscopy and Hoechst 33342 staining assay observed whether the changes of morphological as the result of apoptosis,then detected cell apoptosis by flow cytometry.Results SZ-685C had a dose-dependent inhibitory effect on GH3 cell proliferation and IC50 was (12.9 ± 0.47) μmol/L,MEF(considered as a control group) had little affect in cell proliferation on the concentration of IC50.Inhibitory effects persisted even on removal of SZ- 685C after 12 d,and SZ-685C blocked colony formation ability of pituitary tumor cells.Apoptotic morphological observation of microscope and Hoechst 33342 staining proved apoptosis during treatment of SZ-685C,flow cytometry detection showed that SZ-685C induces 36.4％ of apoptosis,while only 2.0％ in control group.Conclusion SZ-685C inhibits pituitary tumor cell proliferation and induces apoptosis.SZ-685C can be a new anti-patuitary tumor drug for a further study.

AIM: To evaluate the effect of the chosen incision on corneal astigmatism after implantable collamer lens ( ICL) surgery.
METHODS:The study included 195 eyes of 102 patients, and all eyes were randomly divided into two groups: the chosen incision group ( Group A, 97 eyes) and temporal corneal incision ( Group B, 98 eyes ) . Before the operation, and 1wk, 1mo and 3mo after the operation, each patient was examined with corneal topography to observe the changes of corneal astigmatism.
RESULTS: Preoperative corneal astigmatisms were (1-26±0. 35) D in group A and (1. 28±0. 38) D in group B, thus there was no statistically significant difference ( P>0-05). One week postoperatively, the astigmatism were (0.93±0.29)D in group A and (1.32±0.33)D in group B. One month postoperatively, the astigmatism were (0. 85±0.16)D in group A and (1.27±0.18)D in group B. Three months postoperatively, the astigmatism were ( 0. 80±0-13)D in group A and (1. 25±0. 20) D in group B. The differences between the two groups were statistically significant (P<0. 01).
CONCLUSION: The chosen incision can reduce postoperative astigmatism to a certain extent after ICL surgery.

AIM: To analyze the pathogens and drug sensitivity of chronic dacryocystitis in order to provide evidence for clinical drug use.
METHODS:Lacrimal secretion of 171 cases with chronic dacryocystitis was sampled for pathogenic bacteria culture identification and drug sensitivity test. Based on the results, the isolation rate of pathogens strains, the pathogens kind of chronic dacryoeystitis, main pathogens of chronic dacryocystitis, and sensitive drug for pathogens were analyzed.
RESULTS: The isolation rate of pathogens strains was 76. 61% ( 131 cases ). The pathogens constituting the chronic dacryocystitis were predominantly gram-positive coccus,the percentage was 72. 52% (95 cases), among which staphylococcus hominis occupied 27. 48% ( 36 cases), staphylococcus epidermidis 16. 79% (22 cases), streptococcus viridans 12. 98% (17 cases). The majority of these bacteria were sensitive to cefoperazone-sulbactam, tobramycin, gentamicin and levofloxacin. For gram -positive coccus, cefoperazone - sulbactam, gentamicin and tobramycin were the most sensitive drug. For gram-negative bacilli, cefoperazone - sulbactam, tobramycin and levofloxacin were most sensitive drug.
CONCLUSION: Staphylococcus hominis is the main pathogen of chronic dacryocystitis, tobramycin can be used as the first choice for local treatment of chronic dacryocystitis.

Objective To study the preventive strategies through analyzing the poisoning cases from the National Injury Surveillance System (NISS), from 2006 to 2008. Methods Data of poisoning cases was descriptively analyzed from Chinese NISS, from 2006 to 2008. Results The proportion of poisoning cases to all injuries cases from NISS were 2.57%, 2.48% and 2.52% from 2006 to 2008, which ranked sixth in all the injuries causes. Most people being poisoned had junior middle school education and most of them were agriculture/animal husbandry/fishery/water producers or commercial/service personnel. Most of the poisoning incidents were happened at home, always occurred in leisure time - around 8 PM, every day. The common types of poisoning were alcohol,clinical drugs, pesticide and carbon monoxide. Unintentional injuries were the main causes. Self-harm/suicidal cases in the rural areas were more than in the urban areas, with women more than men. The main type of self-harm/suicide related poisoning cases were through drugs or pesticide. ≥65, 15-29and 30-44 year-olds were most commonly seen. Conclusion Alcoholism was the primary type of poisoning injuries which is the highest in young adults ( 15-29 years and 30-44 years). It's important to promote civilized drinking habits and limit access to alcohol for youth. Self-harm/suicide had close relationship with clinical drugs and pesticide. The key points to prevent pesticide and clinical drugs poisoning were safe storage of pesticides, universal security of pesticide, and the supervision on drug producing and marketing. Children and the elderly were the high risk people for carbon monoxide poisoning. Monitoring and intervention must be strengthened.

Quantitative NMR (qNMR) is a technology based on the principle of NMR. This technology does not need the references of the determined components, which supplies a solution for the problem of reference scarcity in the quantitative analysis of traditional Chinese medicines. Moreover, this technology has the advantages of easy operation, non-destructiveness for the determined sample, high accuracy and repeatability, in comparison with HPLC, LC-MS and GC-MS. NMR technology has achieved quantum leap in sensitivity and accuracy with the development of NMR hardware. In addition, the choice of appropriate experimental parameters of the pre-treatment and measurement procedure as well as the post-acquisition processing is also important for obtaining high-quality and reproducible NMR spectra. This review summarizes the principle of qHNMR, the various experimental parameters affecting the accuracy and the precision of qHNMR, such as signal to noise ratio, relaxation delay, pulse width, acquisition time, window function, phase correction and baseline correction, and their corresponding optimized methods. Moreover, the application of qHNMR in the fields of quantitation of single or multi-components of traditional Chinese medicines, the purity detection of references, and the quality analysis of foods has been discussed. In addition, the existing questions and the future application prospects of qNMR in natural product areas are also presented.
