Objective To investigate the influence of internet addictive disorder(IAD) patient' s family cohesion and adaptability effect with Satir family therapy.Methods According with table of random number,the patients (n =120) with IAD were divided into two groups,test group with the 60 patients and the control group with 60.All of subjects were given Linyi mental health center conventional interventions,test group with satir family therapy and the control group without the therapy.Measurements with the addiction self-test scale and the family cohesion and adaptability scale for five months before and after the intervention.The differences of the two groups were analyzed,and then the correlation analysis were used.Results After the intervention of the test group with Satir family therapy,compared to control group,the IAD score (54.28 ± 4.69) and family ideal cohesion (74.64 ±3.22),real cohension (70.42 ± 3.66),ideal adaptability (54.08 ± 5.78),cohesion dissatisfaction degree (5.07 ±1.64) and adaptability dissatisfaction degree (2.23 ± 0.85) score were all had statistically significant (P ＜ 0.05 or 0.01).IAD score,ideal cohesion,real cohension,ideal adaptability and real adaptability score,before and after the intervention between the control group and the test group had statistically significant (P ＜ 0.05 or 0.01).Conclusion The Satir family therapy can improve family cohesion and the adaptability,and also effectively improve the parent-child relationship.

Objective A new hollow fiber liquid phase microextraction combined with high-performance liquid chromatography was developed to determine the concentration of berberine in rat plasma. Methods Parameters that affect the hollow fiber liquid phase microextraction processes were investigated and optimized. The optimized conditions were pH of donor and acceptor phases 12 and 2.0, respectively; extraction time 20 min; stirring speed 800 rpm; and addition of 10 % (w/v) salt. Under the optimized conditions, the preconcentration factor for berberine was 347. Moreover, a rapid and sensitive method was developed to determine berberine in rat plasma by HPLC. Results The calibration curve for berberine was linear in the range of 10-1000 ng/ml (r2≥0.9992). The limit of quantitation for the analyte was 10 ng/ml (S/N=10). The limit of detection for the analyte was 3.3 ng/ml (S/N=3). The intra-day and inter-day precision, and stability (RSD) were less than 6.3%. The average recovery was 96.7% ± 3.82%, and RSD was 4.82%. Conclusions The method is efficient, green, accurate and repeatable. It can be applied in determination of berberine in rat plasma.

To use Agrobacterium rhizogenes-induced hairy roots to create new germplasm of Dianthus caryophyllus, we transformed D. caryophyllus with A. rhizogenes by leaf disc for plant regeneration from hairy roots. The white hairy roots could be induced from the basal surface of leaf explants of D. caryophyllus 12 days after inoculation with A. rhizogenes ATCC15834. The percentage of the rooting leaf explants was about 90% 21 days after inoculation. The hairy roots could grow rapidly and autonomously in liquid or solid phytohormone-free MS medium. The transformation was confirmed by PCR amplification of rol gene of Ri plasmid and silica gel thin-layer chromatography of opines from D. caryophyllus hairy roots. Hairy roots could form light green callus after cultured on MS+6-BA 1.0-3.0 mg/L + NAA 0.1-0.2 mg/L for 15 days. The optimum medium for adventitious shoots formation was MS + 6-BA 2.0 mg/L + NAA 0.02 mg/L, where the rate of adventitious shoot induction was 100% after cultured for 6 weeks. The mean number of adventitious shoot per callus was 30-40. The adventitious shoots can form roots when cultured on phytohormone-free 1/2 MS or 1/2 MS +0.5 mg/L NAA for 10 days. When the rooted plantlets transplanted in the substrate mixed with perlite sand and peat (volume ratio of 1:2), the survival rate was above 95%.

Objective To study the optical imaging quality of multifocal intraocular lens (IOL) following Nd∶YAG laser damage.Methods Three hydrophobic acrylate discs used to make multifocal IOL were placed in line,and the Nd∶YAG laser was used to emit the posterior surface,mid-plane and anterior surface of the discs by gradually increasing the emitting energy to determine the damaged threshold energy of various planes.Eight multifocal IOLs were divided into 2 groups.IOL damage models were established by emitting 12 points along 12 clocks on circle of 3.0 mm in diameter in the group 1 (IOLs NO.1,2,3,4) and 6 points with 1-clock interval on circle of 1.0 mm in diameter in the group 2 (IOLs NO.5,6,7,8) with Nd∶YAG laser.The modulation transfer function (MTF),line spread function (LSF) and United States air force (USAF) test target images of the IOLs were tested under the optical aperture at 2.0,3.0 and 4.5 mm.Results The damage thresholds of laser power were not significantly different among three hydrophobic acrylate discs (Fgroup =1.100,P =0.337),and the thresholds were significantly different among different planes in the discs (Fposition =195.279,P=0.000),with the highest damage threshold in the anterior surface and the lowest damage threshold in the mid-plane of the discs(all at P＜0.01).The shifts of far focus and near focus MTF curves,LSF curves and USAF target images of the IOLs under the 2.0,3.0 and 4.5 mm optical aperture after laser damage were in coincidence with those before laser damage both in group 1 and group 2.The glare phenomenon of the USAF target image was observed at near focus under the 4.5 mm optical aperture both before and after laser damage.Conclusions Multifocal IOL is vulnerable to injury when the laser beam focuses on the midplane,and the anterior surface of IOL can tolerate certain degree of damage.In standard model eye,the MTF curves,LSF curves and USAF target images of multifocal IOL was not impacted by laser induced spots injuries under different pupil diameters.
