Objective To investigate the clinical effects of preoperative eye position training on femtosecond laser-assisted laser in situ keratomileusis(FL-LASIK)? Methods One hundred and sixty-eight myopia patients(328 eyes)scheduled for selective FL-LASIK were randomly divided into the experiment group of 85 cases(166 eyes)and the control group of 83 cases(162 eyes)?The patients in the control group were given the routine preoperative education and the patients in the experiment group received the preoperative intervention of eye position besides routine preoperative education? The two groups were compared in terms of intraoperative changes of eye position,corneal topography and the postoperative visual acuity? Results The frequency of eye position adjustment and machine stopping in the experiment group was significantly smaller than that of the control group(P < 0?001)? But no significant differences were found between the two groups in corneal topography and the postoperative visual acuity(P > 0?05)? Conclusion Preoperative training of eye position may maintain ideal eye position and reduce the frequency of downtime due to eye position adjustment during FL-LASIK,which may ensure the successful completion of FL-LASIK?

Objective To investigate the clinical liver function protective effect of Shuganning injection for treatment of patients with drug poisoning.Methods One hundred and forty patients with drug poisoning consistent with thecriteria of enrollment into the study were admitted into the Department of Emergency Medicine in the First Hospital of Jilin University-the Eastern Division from January 2015 to August 2016, and they were randomly divided into observation group and control group by the computer generated random numbers, 70 cases in each group. After admission, all the cases were treated with routine treatment including detoxification, removal of toxin, organ protection, symptomatic and supporting treatment, etc. Based on the routine treatment, additionally, Shuganning injection 20 mL+ 10% glucose injection 250 mL, intravenous drip slowly, once a day was given in the observation group; the therapeutic course was 14 days in both groups. The changes of serum glutamic transaminase (ALT), aspartate aminotransferase (AST) and total bilirubin (TBiL) levels were determined before and 7 and 14 days after treatment respectively to evaluate the situation of liver function in the two groups.Results Before treatment, there were no statistical significant differences in the levels of serum ALT, AST and TBil in the two groups (allP > 0.05); with the prolongation of treatment, the above-mentioned indexes of the two groups were gradually reduced, on the 14th day after treatment, they reached the lowest levels, and the degree of decrease in level on the 14th day in the observation group was more significant than that in the control group [ALT (U/L): 32.6±10.8 vs. 98.3±34.5, AST (U/L): 39.4±14.3 vs. 138.5±25.6, TBil (μmol/L): 4.8±1.7 vs. 13.2±2.3, allP < 0.05].Conclusion Shuganning injection has a protective effect on liver function in patients with drug poisoning.

Objective To determine the plasma and intracellular concentration of Ara-C by the RPHPLC method and analyse the influence factors and the relationship between the concentration and drug dose.Methods Mononuclear cells and serum of 75 patients with acute leukemia were extracted after the first intravenous infusion of different administration dosage of Ara-C (0.5, 1.0, 2.0 g/m2), and analysed with different chromatographic conditions by RP-HPLC. Results The linear range of Ara-CTP was 0.28-18.96 μg/ml (r =0.998), and the detection limit was 0.28 μg/ml. The detection limit of Ara-C and Ara-U in plasma was 0.0157 μg/ml and 1.034 μg/mnl respectively. In 27 samples preserved for more than 1.5 years, 11 (40.7 %)cases of the plasma concentration of Ara-C were below the detection limit. In 36 samples of mononuclear cell count below 1.5×106/ml, 15 cases (41.7 %) of intracellular concentration of Ara-CTP were below the detection limit. The plasma concentration of Ara-U and intracellular concentration of Ara-CTP were increased with administration dosage of Ara-C increased, and the plasma concentration of Ara-C was not increased. The intracellular concentration of Ara-CTP in old patients over 40 years was tend to in crease with age.Conclusion The RP-HPLC method is simple, rapid, stable, reproducible and applicable for the monitoring of the plasma concentration of Ara-C and intracellular concentration of Ara-CTP. In 0.5-2.0 g/m2 dose range of Ara-C, the plasma concentration of Ara-U and intracellular concentration of Ara-CTP was increased with administration dosage of Ara-C increased.
