Objective To explore effect of rehabilitation training on deglutition disorders of children with cerebral palsy . Methods Twenty-seven children patients from January to June in 2013 were set as control group and thirty-one patients from July 2013 to January 2014 as experiment group. The children in the control group were treated with tube-feeding combined with spoon feeding and bottle-feeding by professional nurse. Children in the experiment group were treated with oral rehabilitation training by professional therapists and nurses apart from the same feeding as in the control group. The two groups were compared in terms of effect of deglutition within 4 weeks, time and rate of removing the stomach tube. Results The recovery of deglutition function in the experiment group was much better than that in the control group , the total effective rate and rate of removing the stomach tube within 3 months were higher and the intubation duration was significantly lower as compared with those of the control group (P < 0.01). Conclusion Rehabilitation training can improve the recovery of deglutition disorders, improve active feeding ability of children with cerebral palsy, shorten time of tube feeding and improve their life quality.

Objective To observe the effects of Suprasorb G and Suprasorb H on peripheral phlebitis above stage Ⅱ. Methods 64 patients with peripheral phlebitis above Stage Ⅱ were randomly divided into the observation group (36 patients) and the control group (28 patients). The observation group used Suprasorb G, and the control group used Suprasorb H. All cases were tested with the change of stage of peripheral phlebitis, the pain score, the red swelling of the skin and the palpable vascular cord. Results After treatment with Suprasorb H or Suprasorb G, there were significant differences in the change of stage of peripheral phlebitis, red swelling of the skin, pain score and the change of palpable vascular cord by self-contrast before and after treatment. Significant differences existed in change of stage of peripheral phlebitis, and red swelling of the skin and the change of palpable vascular cord at 48 and 72 hours, but no change was seen in pain score between 2 groups. Conclusions Suprasorb G and Suprasorb H beth show good effect in treatment of peripheral phlebitis, but Suprasorb G is better than Suprasorb H in improving the stage of peripheral phlebitis, also in reducing the area of red swelling of the skin and the palpable vascular cord with passage of time. But there is no difference in releasing of pain caused by peripheral phlebitis between them.

Objective To explore the correlation of fatigue and life quality of lung cancer patients after chemotherapy. Method A survey was conducted among 54 lung cancer patients after chemotherapy with revised piper fatigue scale ( PFS ) and medical outcomes study (SF-36). Result The total score of PFS of lung cancer patients was (6.44 ± 1.62). The score of SF-36 related area include physical dimension (58.47 ± 5.48), psychological dimension (55.04 ± 4.91) and social dimension (49.21 ± 4.77) environment dimension (52.86 ± 4.98). The total score of PFS was negatively correlated with physical, psychological and environmental dimensions (P<0.05), and not correlated with social dimension (P<0.05). Conclusions The cancer-related fatigue and life quality of lung cancer patient is at medium-severe level, and their life quality is at low level. Positive and effective psychological intervention and psychological nursing can reduce cancer-related fatigue and improve their life quality.

Objective To establish a rapid,specific and sensitive TaqMan real-time fluorescence quantitative PCR assay for detection of murine polyomavirus ( MPyV) .Methods The specific primers and TaqMan probe were designed based on genome sequence of MPyV.The primers amplified a 69 bp fragment.After optimizing the reaction system and reaction condition, the standard curve was plotted by detecting recombinant plasmid standards.The specificity, sensitivity and reproducibility of this method were evaluated.In addition, samples of lungs, spleens and feces obtained from experimentally infected mice and 86 clinical samples were used to validate the efficacy of this real-time PCR assay.Results The specificity assay showed that this assay could specifically detect MPyV and the sensitivity for MPyV was about 100 copies/well.The coefficients of variation ( CV) of both intra-assay and inter-assay were less than 1.13%.All of the samples from experimentally infected mice were positive for MPyV and 3 out of 86 clinical samples were positive by this TaqMan-PCR detection with a positive rate of 3.5%.Conclusions The real-time fluorescence quantitative TaqMan-PCR assay established in this study has high specificity, sensitivity and stability.It can be used for clinical diagnosis, routine detection and epidemiological investigation of murine polyomavirus infections.

Radiotherapy is one of the main therapeutic methods of lung cancer, whereas the lung injury induced by radiotherapy restricts the quality of life and clinical efficacy. It is a challenge to improve the clinical efficacy and reduce lung injury.Based upon clinical experience, certain measures can be taken to alleviate the lung injury after thoracic radiotherapy. The severity and complications of lung cancer and the concurrent chemoradiotherapy-induced injury should be comprehensively understood to establish individual therapeutic strategy. The diagnostic skills, biological characteristics of tumors, the diffusion, metastasis and recurrence of tumors and lymphatic drainage should be mastered and considered in the formulation of treatment target areas to minimize unnecessary radiation for every 1 mm. During the formulation and evaluation of radiotherapy plans, we should understand the biological characteristics of the lung and lung injury repair and stick to the principle of high-dose radiation for small-volume lung rather than low-dose radiation for large-volume lung. A better treatment plan should be established to reduce every 1% of lung DVH as possible even at the expanse of conformality. Simultaneous modulated accelerated radiotherapy and two-phase radiotherapy are employed to distinguish normal tissues from subclinical tumors from the dose and fractioned dose aspects, which further enhance the tumor control and alleviate lung injury. The lung ventilation function is lost at a dose of 20 Gy or higher. Extensive attention should be delivered to reduce the radiation dose to the lung, especially for the repair of non-functional lung fibrosis. Precise and individualized radiotherapy should be adopted to reduce unnecessary radiation and protect the normal lung tissues, which improve the clinical efficacy and enhance the quality of life.

Objective:To examine the correlation between serum Klotho levels and frailty in elderly people.Methods:In this cross-sectional study, 150 community-dwelling elderly people aged 65 years and over were enrolled.Subjects were divided into a frail(n=50, 33.3%), a pre-frail(n=47, 31.3%)and a non-frail(n=53, 35.3%)group based on the Fried phenotype.General participant data, routine laboratory test results, short physical performance battery(SPPB)results and human body composition data were collected.Serum Klotho protein levels were measured by an enzyme-linked immunosorbent assay.The relationship between serum Klotho protein levels and frailty was analyzed by using Spearmen's correlation analysis and Logistic regression analysis.Results:Klotho protein levels were lower in the frail group than in the non-frail group( P=0.001), whereas differences between the frail group and the pre-frail group and between the pre-frail group and the non-frail group were not statistically significant(all P>0.05).When Klotho protein levels were classified into four quartiles, i.e., Q 1, Q 2, Q 3, and Q 4, using three cut-off vales(2.28, 3.52, and 5.09 mg/L), the prevalences of frailty were 51.4%(19/37), 39.5%(15/38), 24.3%(9/37)and 18.4%(7/38), respectively.The prevalence of frailty decreased with increasing Klotho protein levels( χ2=11.204, P=0.011).Spearman correlation analysis showed that the Klotho protein level was negatively correlated with frailty( r=-0.310, P<0.001).Multivariate Logistic regression analysis results showed that age( OR=1.109, 95% CI: 1.011-1.217, P=0.028)and sarcopenia( OR=6.511, 95% CI: 1.279-33.147, P=0.024)were risk factors for frailty, while walking( OR=0.104, 95% CI: 0.033-0.326, P<0.001), a high SPPB score( OR=0.780, 95% CI: 0.627-0.970, P=0.026), and a high Klotho protein level( OR=0.752, 95% CI: 0.581-0.974, P=0.031)were protective factors against frailty. Conclusions:The serum Klotho protein level may be used as a parameter for the assessment of frailty.It is negatively correlated with frailty, suggesting that elderly people with low serum Klotho protein levels are at high risk of developing frailty.
