Initiative of rehabilitation therapy was assessed between group A and group B beforeand 2 months after intervention. Results Group A had no significant increasing of initiative assessment score (P<0.05) 2 months, while theinitiative assessment score of group B increased significantly (P<0.01), even group B was better than group A (P<0.05) after the intervention.Conclusion Individual rehabilitation nursing guidance may facilitate to improve the initiative of SCI patients.

Objective To explore the changes of bone metabolic markers during early stage of preterm infants, as well as the relationship with their nutrition status. Methods Preterm infants with gestational age 30-35 weeks admitted to our Hospital were collected from November 2012 to April 2013. Venous blood samples obtained within 24 hours after birth and between 8:00-9:00 AM two weeks after birth were used to determine the Serum β-CTx, osteocalcin ( OC) and propeptide of type I procollagen (PINP) levels by Electro-Chemiluminescence. Analysis of changes of these bone metabolic markers and their relationship with early stage nutrition related indicators were also performed. Results A total of 60 premature infants were collected. There was no significant correlation among serum β-CTx, OC and PINP within 24 hours after birth ( r=0. 170, P＞0. 05 ) . The Serum β-CTx within 24 hours after birth was negatively correlated with gestational age (r= -0. 603, P＜0. 05), whereas the serum OC within 24 hours after birth was positively correlated with gestational age ( r=0. 581, P＜0. 05 ) . However, PINP wasn′t correlated with gestational age significantly (r=0. 134,P＞0. 05). Serumβ-CTx, OC and PINP at 2 weeks after birth increased significantly from the baseline level detected within 24 hours after birth ( P＜0. 05 ) .Δβ-CTx was positively correlated with ΔOC (r=0. 600,P＜0. 05). There was no significant correlation between ΔPINP and Δβ-CTx (r=0. 045,P＞0. 05), as well as ΔOC and ΔPINP (r=0. 110,P＞0. 05).ΔOC was positively correlated with average daily calorie ( P＜0. 05 ) and average daily P/E ( P＜0. 05 ) , negatively correlated with cumulative loss of caloric ( P＜0. 05 ) . There was no significant correlation between Δβ-CTx or ΔPINP with nutrition related indicators of this study. Conclusions Serum OC within 24 hours after birth of preterm infants and their gestational age are positively correlated, while β-CTx detected at the same time and gestational age are negatively correlated. Vigorous metabolism of premature bone occurs during the first two weeks after birth, as the serum β-CTx, OC and PINP levels increased significantly. We suggest that reasonable calorie intake and appropriate protein calorie ratio at early stage after birth is very important for the development of bone of preterm infants.

Objective To evaluate the effectiveness and safety of autologous granular fat graft applied for penile lengthening and augmentation.Methods After all the superficial ligment and 1/3-2/ 3 part of the deep suspensory-ligament had been cut off for penile lengthening,local pedicaled fasciaadipose flap was designed to fill the depression,the pre-centrifuged autologous granular fat was injected into the space beneath Buck's fascia for penile augmentation.Normal length,pulling penis length,diameter,circumference and complications were evaluated.Results 34 cases were performed and followed up for 3-18 months,both ideal length and diameter increase of penis were achieved.The differences of nomal length,pulling-length,the diameter and circumference were (2.8±0.1) cm,(2.1±0.2) cm,(0.9 ± 0.1) cm,(2.8 ± 0.1) cm,respectively.The common complications included poor wound healing in 4 cases,preputial edema and subcutaneous scleroma in 8 cases for 3 months.Conclusions Autologous granular fat graft for penile augmentation during the lengthening surgery is a reliable and effective method and easy procedure.Detail processing can decrease the complications.

Objective To investigate the effect of long-term proton pump inhibitor on osteoporosis in elderly patients.Methods A total of 150 patients with peptic ulcer treated in our hospital from January 2011 to January 2015 were selected as the observation group.150 healthy subjects were selected as the control group.The age,height,body weight and PPI time of the two groups were recorded.The changes of bone mineral density before and after treatment were measured by bone mineral density analyzer,ineluding lumbar L1-4,radial density and ulna density.The changes of bone mineral density were observed and recorded in the observation group before treatment,six months,1 year and 2 years after treatment.Results After treatment,the levels of gastrin were significantly increased in the observation group,and the serum calcium concentration and bone mineral density were significantly decreased (P＜0.05).The density of lumbar vertebrae,radius and ulna was significantly lower in observation group than those of control group (P＜0.05).With the prolongation of PPIs,lumbar vertebrae,radius and ulna density in observation group showed a decreasing trend.Conclusion Long-term application of proton pump inhibitors in elderly patients can cause bone loss.

Objective To explore the effect of nursing intervention on the hyponatremia after cervical spinal cord injury. Methods 60 patients with the hyponatremia after cervical spinal cord injury were divided into a control group (n=30) and a nursing intervention group (n=30). The control group was just given a general treatment on hyponatremia, while the nursing intervention group was given a systematic nursing intervention of hyponatremia by the duty nurse concerned. The serum sodium value and the course of disease of the two groups were both analyzed a month after nursing intervention. Results Compared with the control group, the value of serum sodium in the nursing intervention group got a significant rise with a shorter course and a less relapsed cases (P<0.01). Conclusion Nursing intervention may improve the hyponatremia after cervical spinal cord injury.

Objective To study the effects of integrative body-mind training with cognitive rehabilitation based on the sensory integration training theory on executive function and anxiety and depression mood in patients with traumatic brain injury.Methods 85 cases were randomly divided into the control group (42 cases) and the treatment group (43 cases).The control group took targeted cognitive rehabilitation with sensory integration training theory and the treatment group was given targeted integrative bodymind training based on this training.Before training and after 3 months,the cognitive function and executive function were detected by the Behavioral Assessment of Dysexecutive Syndrome (BADS); the cognitive dysfunction were evaluated by Loewenstein Occupation Therapy Cognitive Assessment (LOTCA); Anxiety and Depression were evaluated by Self-rating Depression Scale (SDS) and Self-Rating Anxiety Scale (SAS).Results There was no marked differences in BADS,LOTCA,SDS and SAS scores before treatment; Compared with the control group,they were much improved after training; Moreover,they were much more improved in the treatment group than those of the control group.Conclusions Integrative bodymind training with cognitive rehabilitation based on the sensory integration training theory can improve the executive function and regulate the mood on cognitive dysfunction in patients with traumatic brain injury.

Objective To evaluate the efficacy and safety of different bismuth-based quadruple therapies for Helicobacter pylori (H.pylori) eradication.Methods From December 2012 to October 2013,240 patients with H.pylori infection were collected and evenly divided into clarithromycin group,levofloxacin group,furanzolidone group and metronidazole group.Each group received bismuth potassium citrate 220 mg,esomeprazole 20 mg and amoxicillin 1 000 mg twice daily.In addition,each group received clarithromycin 500 mg,levofloxacin 200 mg,furanzolidone 100 mg,and metronidazole 400 mg,respectively.The course of treatment was 10 days.At least four weeks after the end of therapy and withdrawal the medicine,patients underwent fasting 13C-urea breath test or 14C-urea breath test.The negative result indicated as successful H.pylori eradication.The adverse effects were observed and recorded during treatment.The rate of H.pylori eradication was analyzed by the intention to treat (ITT) analysis and per protocol (PP) analysis.Chi-square test was performed for eradication rate comparison among groups.Results According to ITT analysis,the eradication rate of clarithromycin group,levofloxacin group,furanzolidone group and metronidazole group was 81.67％ (49/60),88.33％ (53/60),93.33％ (56/60) and 73.33％ (44/60),respectively,and according to PP analysis which was 85.96％ (49/57),89.83％ (53/59),94.92％ (56/59) and 75.86％ (44/58),respectively.The differences among four groups were statistically significant (x2 ＝10.13 and 9.89,both P＜0.05).The differences between furanzolidone group and metronidazole group were statistically significant (x2 =8.64 and 8.55,both P＜0.01).There were no statisticaly significant differences in adverse effects among the four groups (x2 =0.47,P＞0.05).Conclusion The H.pylori eradication rate is high in furanzolidone contained bismuth based quadruple therapy and with good safety,which could be the first line treatment for H.pylori eradication.

Objective To study the effect of the respiratory amplitude on the dose distribution of volumetric modulated arc therapy (VMAT).Methods Respiratory motion simulation phantom (QUASAR) was used to simulate the respiratory movement from head to toe,and a two-dimensional ionization chamber matrix was used to collect the dose distribution in isocenter with different respiratory amplitude.Verisoft software and absolute dose analysis were used to analyze dose distribution,percentage errors of absolute dose in isocenter,passing rates of radiation field for the data collected,and results were compared to planned dosage.Results The effect on isocenter target dose of respiratory motion was below dose tolerance 5％ (t =-22.614--10.756,P ＜ 0.05).The respiratory movement made the dose on the edge of the target area higher,with fewer hot spots and more cold spots in the target area.As the respiratory amplitude increased,the effect of respiratory movement on the overall dose distribution in the target area was greater.The difference of the whole beam γ passing rate between 6,8,10 mm and stationary state was significant (t =3.095,8.685,14.096,P ＜ 0.05).The difference of target γ passing rate between 8,10 mm and stationary state was significant (t =6.081,9.841,P ＜0.05).Conclusions The respiratory movement could cause the dose transmission errors of VMAT,the error increased with increased range of motion.The actual radiation dose for normal tissues along the direction of respiratory movement on the target edge was higher than what was planned.

Objective:To investigate the effect of resveratrol ( Res ) on endoplasmic reticulum stress induced by cerebral ischemia/reperfusion(I/R)injury in rats.Methods:The seventy-two male SD rats were divided randomly into three groups(n=20):sham operation group ( group S ) , I/R group and Res-treatment group ( group R ) .Focal cerebral I/R model was induced by electrocoagulation of left middle cerebral artery and occlusion of bilateral common carotid arteries followed by reperfusion after 30 min.The rats in Res group were treated with Res(50 mg/kg)i.p.7 d before the operation,once a day for 7 d.Neurological deficits were assessed at 24 h post-injury,followed by collecting the brain tissues.Cerebral infarct size was detected by TTC staining,and the water content of brain tissue were measured by wet-dry weight method.The expression of GRP78,p-PERK and CHOP proteins were deter-mined by immunohistochemistry and Western blot analysis.Results:Compared with sham group,the neurological deficit score and the brain water content were significantly increased(P<0.05),cerebral infarct size was enlarged(P<0.05),and the expression of GRP78, p-PERK and CHOP were up-regulated in I/R group(P<0.05).At the corresponding time,compared with I/R group,the neurological deficit score and the brain water content were markedly decreased(P<0.05),cerebral infarct size was smaller(P<0.05),the level of GRP78 was notablely increased(P<0.05),while the expression of p-PERK and CHOP were down-regulated in Res group(P<0.05). Conclusion:Resveratrol plays a protection role in ischemia-reperfusion injury, through inhibiting the endoplasmic reticulum stress in rats.
