Objective To explore the effect of individual rehabilitation nursing guidance on the initiative of rehabilitation therapy of spinalcord injury patients. Methods 50 spinal cord injured patients were divided into conventional group (group A) and individualized group(group B). Group A was given conventional rehabilitation nursing guidance. Group B was given special rehabilitation nursing guidance consideringthe patients' and their families' requirement. 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 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 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 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 estimate the correlations between chronic idiopathic urticaria (CIU) development and interrelated autoantibodies,including anti-high affinity immunoglobulin E receptor (anti-FcεRI) antibody,anti-immunoglobulin E (anti-IgE) antibody,anti-Helicobacter pylori (HP) antibody and antithyroglobulin antibody (TGAb).Methods This study included 100 patients with CIU,100 patients with acute urticaria (AU) and 100 healthy controls.Autologous serum skin test (ASST) was performed and allergens were detected by fluorescence-based enzyme linked immunosorbent assay (ELISA) in each subject.Serum levels of total IgE,anti-FcεRI antibody,anti-IgE antibody,anti-HP antibody and TGAb were measured.Chi-square test,analysis of variance,and Wilcoxon rank sum test were conducted for statistical analysis.Results The positivity rate of ASST was 53％,12％ and 0 respectively in patients with CIU,patients with AU and healthy controls,respectively.Food or inhalant allergens were detected in 86％ of the patients with AU,but not detected in any of the patients with CIU or healthy controls.Patients with CIU showed significantly higher levels of anti-FcεRI antibody and anti-IgE antibody compared with patients with AU and healthy controls (all P ＜ 0.05).The serum IgE level in healthy controls was statistically lower than that in patients with AU (T =226.00,P ＜ 0.05),but higher than that in patients with CIU (T =190.00,P ＜ 0.05).ASST-positive patients with CIU had a higher level of serum anti-FcεRI antibody (T =101.73,P ＜ 0.05),but a similar level of serum anti-IgE antibody compared with ASST-negative patients with CIU (T =312.04,P ＞ 0.05).No significant differences were observed in the positivity rate of anti-HP antibody (29％,19％ and 23％,P ＞ 0.05) or TGAb (18％,15％ and 11％,P ＞ 0.05) between the patients with CIU,patients with AU and healthy controls.Both anti-HP antibody-positive patients and TGAb-positive patients with CIU showed a significantly higher positivity rate of anti-FcεRI antibody (all P ＜ 0.01),but a similar positivity rate of anti-IgE antibody compared with the patients with AU and healthy controls (all P ＞ 0.05).Conclusions Anti-FcεRI antibody and anti-IgE antibody are present in patients with CIU,and may play a certain role in the pathogenesis of CIU.

OBJECTIVE To investigate the produce of extended-spectrum ?-lactamases(ESBLs) and the presence of genotype of the ?-lactamases-encoding genes in Klebsiella pneumoniae isolated from the 98th Hospital of PLA,Huzhou,Zhejiang Province,China.METHODS Twenty-five strains of K.pneumoniae were isolated from the inpatients between Sep 2005 and Apr 2006.ESBLs were tested by phenotypic confirmatory tests recommended by CLSI.Twenty-one kinds of ?-lactamases genes of blaTEM,blaSHV,blaLEN,blaOKP,blaCTX-M-1 group,blaCTX-M-2 group,blaCTX-M-9 group,blaOXA-1 group,blaOXA-2 group,blaOXA-10 group,blCARB,blaPER,blaVEB,blaGES,blaLAP,blaDHA,blaACT/MIR,blaCMY/MOX,blaFOX,blaCMY/LAT,and blaACC were analyzed by PCR and verified by DNA sequencing.RESULTS In 25 strains of K.pneumoniae,the positive,negative,and "uncertainty" rates of ESBLs were 56.0%,20.0%,and 24.0%,respectively.The positive rate of genes of blaTEM,blaSHV,blaCTX-M-1 group,blaOXA-10 group,blaLAP,and blaDHA were 80.0%,4.0%,4.0%,80.0%,4.0% and 32.0%,respectively.The 15 kinds of rest genes were all tested negative.The total positive rate of 21 kinds of ?-lactamases gene was 92.0%.Among them,the blaLAP-2 gene sequence of the HZ12593 strain has been registered in GenBank(GenBank Accession Number: EU529981).CONCLUSIONS There are higher rate of ESBLs-producing strains in K.pneumoniae isolated from the inpatients,and at least 6 kinds of ?-lactamases gene existed.Both genes of blaTEM and blaOXA-10 group are the most common genotypes.Carring blaDHA Gene may influence the result of phenotypic confirmatory test for ESBLs in K.pneumoniae.

Pancreatic cancer is a commonly malignant gastrointestinal tumor with an significantly increasing incidence.Those patients without nonspecific symptoms at early stage had mostly lost the opportunity of surgical therapy when pancreatic cancer was detected at advanced stage,and its prognosis is poor.Therefore,it is rather important to improve the early diagnosis of pancreatic cancer.In recent years,proteomics is developing rapidly.Proteomics technologies have been widely used in clinical research.Using proteomics technology screening pancreatic cancer tumor markers becomes the research focus,thus we try to find a kind of or a group of pancreatic tumor markers,so as to improve the diagnosis of pancreatic cancer.

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.
