Objective To study the effects of peroxisome proliferators-activated receptor (PPAR) ? on the growth of human hepatocellular carcinoma cells and explore the roles of phosphatase and tensin homologue deleted on chromosome ten (PTEN) and phospho-Akt in this process. Methods SMMC-7721 cells were treated with 15-d-PGJ2 or pioglitazone, which were two kinds of PPAR? ligands, at different concentrations. The viability of SMMC-7721 cells was evaluated by MTT assay. The cell cycle was analyzed by flow cytometry. PTEN mRNA level was determined by RT-PCR. The protein expressions of PTEN and pAkt were measured by Western blot analysis. Results It was demonstrated through MTT assay that both 15-d-PGJ2 and pioglitazone had an inhibitory effect on the growth of SMMC-7721 cells in a time- and dose- dependent manner. According to flow cytometry detection, more cells were arrested in G0/G1 phase. Increased expression of PTEN mRNA was detected in 15-d-PGJ2 or pioglitazone-treated cells through RT-PCR. Increased expression of PTEN protein and decreased expression of pAkt were confirmed by Western blot analysis. Conclusion The ligands of PPAR? could inhibit SMMC-7721 cells proliferation in a time- and dose- dependent manner. The upregulation of PTEN may be involved in the underlying mechanism.

AIM: By comparing the aspheric and multifocal Toric intraocular lens and the aspheric intraocular lens in cataract patients,to observe the patients` visual quality,to evaluate the patients` distance visual acuity,near visual acuity,Pseudo-accommodative power,residual astigmatism,the rotational stability of AcrySof IQ Toric Restor intraocular lens (IOLs),contrast the rate of off-distance glass,the rate of off-near glass and patient satisfaction after the implantation of AcrySof IQ Toric Restor IOL in the cataract patients with preexisting corneal astigmatism.METHODS:Carried out in 46 patients (48 eyes) with age-rated cataract who receiving phacoemulsification and implantation of artificial lens in our department during February 2014 to June 2016.All the cases were randomly divided into 2 groups: experimental group: 23 cases (24 eyes),AcrySof IQ ReSTOR Toric IOL was implanted after phacoemulsification;control group: 23 cases (24 eyes),AcrySof IQ was implanted.Uncorrected distance visual acuity (UCDVA) and best corrected distance visual acuity (BCDVA),uncorrected near visual acuity (UCNVA) and best-corrected near visual acuity(BCNVA),Pseudo-accommodative power,residual astigmatism,preoperative and postoperative corneal astigmatism,the rate of off-distance glass,the rate of off-near glass and patient satisfaction were measured at 6mo postoperatively follow-up.RESULTS: BCDVA and BCNVA were not statistically different between the two groups(P<0.05).At 1wk,1,3 and 6mo postoperatively of UCDVA the experimental group were statistically better than the control group (P<0.05).UCNVA were also statistically better than the control group (P<0.05).The mean residual astigmatisms 1wk,1,3 and 6mo postoperatively were statistically differences between the control group and experimental group (P<0.05).At 6mo postoperatively,patients satisfaction of experimental group were significantly better than control group (P<0.05).Spectacles independence for near vision achieved 83% and 17% in experimental group and control group,experimental group were statistically better than control group(P<0.05).Spectacles independence for distance vision achieved 92% and 67% in experimental group and control group,experimental group were statistically better than control group(P<0.05).CONCLUSION:The results indicate that AcrySof IQ ReSTOR Toric IOLs may provide a better uncorrected distance visual acuity and uncorrected near visual acuity,which can significantly reduce preexisting corneal astigmatism in cataract surgery,improve spectacles independence for distance vision and spectacles independence for near vision,have a high patient satisfaction.

Objective To evaluate the clinical effect of the enteral nutrient(Pediasure) on making improvements in nutritional status of children with anorexia.Methods Thirty children were treated with pediasure for 2 months, twice a day, and height(Ht),weight(Wt),AG,TSF,SSF,ASF,RBC,Hb were measured before and after treatment and their appetites,alimentary canal reactions were recorded.Results Compared with the effects after 2 months, the average Ht,Wt,AG,SF all increased, and there was significant difference between pretreatment and after treatment(P0.05). All of the 30 children had no adverse reactions during treatment.Twenty-two children (73.33%) had better appetites and increased the amount of eating after treatment.Conclusion The study suggests that pediasure may be safely used in the treatment of children′s anorexia and effectively improve patients′ nutrition without adverse reactions.

OBJECTIVETo study the anti-immune inflammation efficacy and toxicity of Tripterygium wilfordii decoction, in order to provide experimental basis for studies on its "efficacy-toxicity" correlation.

METHODThe delayed hypersensitivity model was established by dinitrofluorobenzene in mice. Different doses of T. wilfordii decoction was administered for 5 consecutive days. The ear swelling inhibition ratio and the toxic action were observed. After the final administration, the biochemical indexes of PGE2, TNF-α, IL-2, ALT, AST, PA, TBA, TBIL in serum were detected, and the visceral indexes of heart, liver, spleen and kidney were measured.

RESULTThe DNFB-induced ear swelling could be notably inhibited by multiple oral administration of T. wilfordii decoction, with the ED50 and its 95% confidence limit of 0.34 (0.21-0.42) g x kg(-1). The contents of PGE2, TNF-α, IL-2 in serum decreased in a dose-dependent manner. The activities of serum AST, ALT, TBA, TBIL and the PA content reduced.

CONCLUSIONT. wilfordii decoction shows a significant anti-immune inflammation efficacy within the dosage range between 0.59 and 2.34 g x kg(-1) in a dose-dependent manner. With a certain hepatotoxicity, high dose (2.34-4.68 g x kg(-1)) of T. wilfordii decoction can cause substantial liver injury, with a dose dependence in liver function index. Therefore, the efficacy and toxicity of T. wilfordii is dose dependent, which provides reference for preventing adverse drug reactions in clinic and developing early-warning schemes and ensure the clinical medication safety of T. wilfordii.
