Objective:To improve the safety,rationality and efficacy of medication for ovarian cancer patients complicated with cirrhosis by the participation of clinical pharmacists in the therapy. Methods:Clinical pharmacists participated in the therapy for an ovarian cancer patient with cirrhosis,and provided a rational and individualized therapeutic regimen through the drug experience of clinical pharmacists as well as the relevant medical guides and literatures. Results:The therapeutic efficacy was increased by the participation of clinical pharmacists in the therapy,the potential risk of the chemotherapy was avoided and the security of medication was assured. Conclusion:The participation of clinical pharmacists in therapeutic practice can improve the normalization of pharmacotherapy for ovarian cancer patients with cirrhosis,which also can provide ideas and methods for treating the similar patients.

DNA repair processes play a role in the development of drug resistance which represents a huge obstacle to leukemia chemotherapy. Histone H2AX phosphorylation (ser139) (γH2AX) occurs rapidly at the onset of DNA double strand break (DSB) and is critical to the regulation of DSB repair. If DNA repair is successful, cells exposed to anti-neoplastic drugs will keep entering the cycle and develop resistance to the drugs. In this study, we investigated whether γH2AX can be used as an indicator of tumor chemosensitivity and a potential target for enhancing chemotherapy. K562 and multi-drug resistant cell line K562/A02 were exposed to adriamycin (ADR) and γH2AX formed. Flow cytometry revealed that percentage of cells expressing γH2AX was increased in a dose-dependent manner and the percentage of K562/A02 cells was lower than that of K562 cells when treated with the same concentration of ADR. In order to test the potential of γH2AX to reverse drug resistance, K562/A02 cells were treated with PI3K inhibitor LY294002. It was found that LY249002 decreased ADR-induced γH2AX expression and increased the sensitivity of K562/A02 cells to ADR. Additionally, the single-cell gel electrophoresis assay and the Western blotting showed that LY249002 enhanced DSBs and decreased the expression of repair factor BRCA1. These results illustrate chemosensitivity can partly be measured by detecting γH2AX and drug resistance can be reversed by inhibiting γH2AX.

ObjectiveTo investigate the effect of low frequency stimulation on motor function of stroke patients.Methods50 stroke patients were randomly divided into control group and treatment group with 25 cases in each group. Patients of control group received neuromedical and Bobath technical treatment; cases of treatment group received low frequency stimulation besides the above two methods. All patients were assessed respectively with the Fugl-Meyer Assessment and Clinical Nerve Function Impaired Scale at the admission and on 20 days after treatment.ResultsThe motor functions of both groups were improved (P<0.05). But the recovery of treatment group was superior to the control group (P<0.05).ConclusionLow frequency stimulation can promote the stroke patients' motor function recovery.

Objective To explore the effects of virtual reality (VR) combined with motor imagery therapy on the upper limb function of hemiplegic stroke survivors.Methods Thirty-nine hemiplegic stroke patients were divided randomly into a treatment group (n =20) and a control group (n =19).Both groups were treated with motor imagery therapy,but the treatment group also received VR training lasting 20 min/day,6 days/week for 8 weeks.All of the patients were assessed with the Fugl-Meyer (FMA) upper limb assessment,the modified Barthel index (MBI) and electromyography at the beginning and after eight weeks of treatment.Results Before the intervention there was no significant difference between the groups in any of the assessments.After eight weeks of treatment,all the assessment results in the treatment group were significantly better than those in the control group.Conclusion Virtual reality combined with motor imagery therapy can distinctly improve the upper limb motor function of hemiplegic stroke survivors and their ability in the activities of daily living.
