The mechanism and pathophysiological progress of ischemia/reperfusion are complicated,and all the factors influence each other.This article summarized recent development on the related factors of inflammatory reaction mechanism.

OBJECTIVE:To observe clinical efficacy and safety of Shuxuening injection in the adjunctive treatment of traumat-ic subarachnoid hemorrhage. METHODS:96 patients with traumatic subarachnoid hemorrhage were randomly divided into control group and observation group with 48 patients in each group. Control group was given Tranexamic acid injection,Nimodipine injec-tion and Citicoline injection,daily lumbar punctrive and determined intracranial pressure and drained cerebrospinal fluid via lumbar puncture;observation group was additionally given Shuxuening injection 20 ml added into 5% Glucose injection 250 ml,ivgtt,qd. Both group were treated for consecutive 2 weeks. Clinical efficacy of 2 groups were observed,and GCS and MCA were also ob-served before and after treatment;ADR of 2 groups were recorded. RESULTS:Excellent rate of observation group(60.42%)was significantly higher than that of control group(31.25%),with statistical significance(P<0.05). Before treatment,3 and 5 days af-ter treatment,there was no statistical significance in GCS and MCA between 2 groups(P>0.05);7 and 14 days after treatment, GCS of 2 groups increased significantly while MCA decreased significantly,and the observation group was better than the control group,with statistical significance (P<0.05). The incidence of cerebral vasospasm,cerebral infarction and cerebral hemorrhage were 8.33%,4.17%and 4.17%in observation group,and those of control group were 16.67%,12.50%and 16.67%;the observa-tion group was significantly lower than the control group,with statistical significance(P<0.05). CONCLUSIONS:Shuxuening in-jection shows significant therapeutic efficacy in the adjunctive treatment of traumatic subarachnoid hemorrhage,with low incidence of ADR.

AlM:To investigate the efficacy of highly hydrophilic soft contact lenses for persistent corneal epithelial defects. METHODS: ln this retrospective case analysis, 28 patients ( 28 eyes ) with persistent corneal epithelial defects after anterior segment surgery from January 2011 to June 2013 in our hospital were reviewed. After regular treatment for at least 2wk, the persistent corneal epithelial defects were treated with highly hydrophilic soft contact lenses, until the corneal epithelial healing. Continued to wear the same lens no more than 3wk, or in need of replacement the new one. All cases were followed up for 6mo. Key indicators of corneal epithelial healling, corneal fluorescein staining and ocular symptoms improvement were observed.RESULTS: Twenty-one eyes were cured (75. 00%), markedly effective in 5 eyes (17. 86%) , effective in 2 eyes (7. 14%), no invalid cases, the total efficiency of 100. 00%. Ocular symptoms of 25 cases (89. 29%) relieved within 2d, the rest 3 cases (10. 71%) relieved within 1wk. The corneal epithelial of 6 cases ( 21. 43%) repaired in 3wk, 13 cases (46. 43%) in 6wk, 7 cases (25. 00%) in 9wk, 2 cases ( 7. 14%) over 12wk. There were no signs of secondary infection. And no evidence of recurrence in 6mo.CONCLUSlON: Highly hydrophilic soft contact lenses could repair persistent corneal epithelial defects after anterior segment surgery significantly, while quickly and effectively relieve a variety of ocular irritation.

Background Curcumin derives from the rhizome of curcuma longa.It has proven to have an antiproliferative effect in previous studies on vast majority of endothelial and epithelial cells,however,the study of its inhibiting effect on the proliferation of retinal pigment epithelial (RPE) cells and underlying mechanism is rare.Objective Aim of this study was to investigate the potential inhibitory effect of curcumin on the proliferation of cuhured human RPE cells in vitro and its possible mechanism.Methods Human RPE cells harvested by trpsinEDTA were suspended in DMEM/F12 medium with serial dilutions of curcumin (5,10,15,20 mg/L),and the human RPE cells cultured by DMEM/F12 without curcumin were used as control.The proliferation value of human RPE cells (A value) was measured by water-soluble tetrazole-1 (WST-1) assay,the optimized dose of antiproliferation of curcumin was determined and applied for further experimental process.Apoptosis and cell cycle of human RPE cells were detected by flow cytometric analysis at 48 hours and 72 hours after curcumin treatment.The ultrastructure profile of the cells were examined by transmission electron microscopy (TEM).Western blot analysis was performed to measure the relative expressing level of the pro-apoptotic factors p53,p21 WAF1/CIP1 and proliferating cell nuclear antigen (PCNA) in the cells,respectively.Factorial design of two factor analysis of variance of SPSS 17.0 software was used to compare the difference of A values of the cells among the various groups and time points,and independent-sample t test was used to compare the differences of apoptosis rate and cell ratio in different cycles between curcumin group and control group.Results WST-1 assay showed that the A value was gradually reduced with the increase of curcumin dose (F tion =96.55,P =0.00),and gradually increased with the lapse of time (Ftime =4634.28,P =0.00).The early apoptotic rate of the cells was (13.37±1.26) ％ in the curcumin group 48 hours after treated by 15 mg/L curcumin,and that of the control group was (7.03 ±0.37) ％,with a significant difference between them (t =8.33,P=0.00).In 72 hours after treated by 15 mg/L curcumin,the early and middle-late apoptotic rates of the cells were (15.97±0.16) ％ and (0.26±0.03) ％,which were significantly higher than those of the control group (7.29±0.37) ％ and (0.14±0.02) ％ (t=37.80,P=0.00;t=7.44,P=0.00).The cell ratio of G0/G1 phase in the curcumin group was (57.17±1.17)％ 48 hours after treated by 15 mg/L curcumin,and that in the control group was (67.73± 1.10)％,showing a significant difference (t =11.40,P =0.00).M itochondrial swelling and vacuolar degeneration were seen in the cells after treated by 15 mg/L curcumin.The relative expression levels of p53 and p21WAF1/CIP1 protein in the cells were higher in the curcumin group than those of the control group at 24,48 and 72 hours (all at P＜0.05),but the expression levels of PCNA protein were lower in the curcumin group than those of the control group in various time points (all at P ＜ 0.05).Conclusions Curcumin can effectively inhibit the proliferation of human pigment epithelial cells in a dose-and time-dependent manner.P53 pathway may participate in anti-proliferating process.

In order to enhance the survival rate of abalone larvae, antibiotic susceptibility tests were performed on the bacteria isolated from whitened postlarvae, biofilm and the pond water of abalone (Haliotis diversicolor superteta) and proven to be virulent pathogens by challenge tests. API tests indicated that the isolates were mainly comprised of Vibrio alginolyticus, vibrio cholerae, Vibrio parahaemolyticus, the total Vibrio number of which was seventeen and made up about 50% of the total population. Among vibrios, Vibrio alginolyticus was the dominant strain (11 isolates) and made up 70%. Antibiotic susceptibility tests demonstrated that while majority isolates exhibited relatively high sensitivities toward streptomycin, erythromycin and gentamycin, they nevertheless displayed resistance to tetracycline and novobiocin. Results clearly indicated that streptomycin, erythromycin and gentamycin could be potentially used to suppress vibrio growth and hence improve abalone postlarval survival rate.
