Conclusion Clinical pharmacist intervention has a positive effect on the application of antibacterial drugs,which can significantly reduce the use of antimicrobial drugs and reduce the hospitalization days.

Objective To study the effect of comprehensive Chinese medicine therapy,including Chinese herbal medicine fumigation,massage,and quadriceps exercise,on adipokines of visfatin and chemerin content in joint fluid of patients with knee osteoarthritis (KOA),and to explore its possible therapeutic mechanism for KOA.Methods A total of 60 cases of KOA patients were randomly divided into treatment group and control group,30 cases in each group.The treatment group was treated with comprehensive Chinese medicine therapy,and the control group was treated with Chinese medicine fumigation alone.After treatment for 2 weeks,the clinical efficacy of both groups was evaluated,and the changes in the scores of the Western Ontario and McMaster Universities Arthritis Index (WOMAC)were observed.Moreover,the contents of visfatin and chemerin in jointfluid were examined.Results (1) The total effective rate of the treatment group was 96.7％ and that of the control group was 83.3％,the difference being significant (P ＜ 0.01).(2) After treatment,WOMAC scores of both groups were obviously decreased(P ＜ 0.01 compared with those before treatment),and the decrease in the treatment group was superior to that in the control group (P ＜ 0.01).(3) The contents of visfatin and chemerint in joint synovial fluid of both groups were decreased (P ＜ 0.01 compared with those before treatment),and the decrease in the treatment group was superior to that in the control group(P ＜ 0.05).Conclusion The comprehensive Chinese medicine therapy of Chinese herbal medicine fumigation,massage and quadriceps exercise is effective for the treatment of KOA,and can decrease the contents of visfatin and chemerin in joint fluid of KOA patients,which may be one of its therapeutic mechanisms.

Objective To clarify the mechanism of immediate early response gene 5 (ler5)transcription induced by radiation. Methods Deletant construction, site-specific mutagenesis,electrophoretic mobility shift assay (EMSA) and chromatin immunoprecipitation (ChIP) were used to forecast the promoter region,binding sites and transcription factors of Ier5 gene in HeLa cells.Results The promoter region of Ier5 gene might be in the region of Ier5 -8 deletant ( -408 - -238 bp).The Ier5 gene had two transcription factors of GCF and NFI,and GCF had two binding sites located in the region of - 388 - - 382 bp and - 274 - - 270 bp of Ier5 promoter.The binding site of NFI was located in - 362 --357 bp of Ier5 promoter. GCF could inhibit the expression of Ier5 gene and this inhibition was diminished when the radiation dose increased. In contrast, NFI increased the expression of Ier5.Conclusions The most possible region of Ier5 promoter is from -408 to - 238 bp which has two binding sites for the radiosensitivity transcription factors of GCF and NFI that could negatively and positively regulate the expression of Ier5 respectively.

Objective: To investigate whether silencing UCP2 can sensitize cervical cancer cell line Siha to radiation. Methods: Siha cells were transfected with UCP2 siRNA and then irradiated by X-ray. The radiosensitivity of Siha cells was verified by colony formation, CCK-8, apoptosis and immunofluorescence assays. The mitochondrial membrane potential and the production of reactive oxygen species (ROS) were detected to further explore the related mechanism. Results: RT-PCR and Western blot assays showed that the expression of UCP2 in Siha cells was increased after irradiation and the UCP2 siRNA successfully silenced the expression of UCP in cells. According to the survival curves, the D₀, D_q, N and SF₂ were 1.54, 1.31, 2.31 Gy and 0.52 for siUCP2 group, 2.50, 3.64, 4.30 Gy and 0.83 for blank control group, and 3.34, 2.16, 1.91 Gy and 0.69, for siNC group, respectively. The radiosensitivity enhancement ratio of silent group was 0.62 and 0.46, compared with blank control group and negative control group, respectively. The proliferative activity of cells in the silent group was lower than that in the control group (t=13.2, P<0.05). Apoptosis levels in the silent group were significantly higher than those in the control group after irradiation(t=3.14, P<0.05). At 4 h after irradiation, the ROS production in the silent group was significantly higher than that in the control group (t=19.10, P<0.05). At 24 h after irradiation, the mitochondrial membrane potential of Siha cells in the silent group was significantly lower than that in the control group (t=4.18, P<0.05). Conclusions The radiosensitivity of Siha cells is enhanced after UCP2 silencing, and thus UCP2 may applicable as a new target for radiosensitization of cervical cancer cells.

Objective:To explore any effects of combining virtual reality training with aromatherapy in caring for Alzheimer′s disease patients in a nursing home.Methods:Fifty nursing home residents with Alzheimer′s were divided at random into an observation group and a control group, each of 25. Both groups received routine rehabilitation, while the observation group was additionally given 45 minutes of virtual reality training combined with aromatherapy, 3 times a week for 6 months. Both groups′ cognition was then evaluated using the MMSE and an Alzheimer′s cognition assessment scale (ADAS-cog). Psycho-behavioral symptoms were quantified using the Alzheimer′s disease pathological behavior scale (BEHAVE-AD). Motor functioning was quantified using the timed up and go test (TUGT), the 30-second sit-to-stand test (30sCST), the 30-second arm curl test (30sACT) and the sit-and-reach test (CSRT). Ability in the activities of daily living (ADL) and life quality were quantified using the activity of daily living scale and of the quality of life scale for Alzheimer′s disease (QOL-AD) before and after the intervention.Results:After the intervention the average MMSE, ADAS-cog, BEHAVE-AD and ADL scores of both groups had improved significantly, with the average improvement in the observation group significantly greater than that in the control group. The TUGT, 30sCST, 30sACT and CSRT results of both groups were also significantly better, with those of the observation group again significantly superior, on average, to the control group′s results. The average QOL-AD score in the observation was significantly improved after the intervention, and was then significantly better than the control group′s average.Conclusions:Virtual reality training combined with aromatherapy can significantly improve the cognition, psycho-behavioral symptoms, activity in daily living, motor functioning and life quality of Alzheimer′s patients in a nursing home. It is worthy of promotion and application in nursing homes.
