At present,in the opinions of the domestic and foreign scholars,the only hope of long-term survival even cure of hilar cholangiocarcinoma was obtained by radical resection(ie R0 resection).The application of preoperative assessment with appropriate and comprehensive strategies can judge the respectability and Intraoperative safety accurately to the tumor,thereby it can improve the radical resection rate and safety of patients with hilar cholangiocarcinoma.In this paper,preoperative assessment strategies are reviewed.

[Objective]To investigate the relationship between inoculation dose of staphylococcus aureus versus radiological and microbiological changes of rabbit tibial infection with bone defect.[Methods]Staphylococcus aureus(ATCC 29213) with total number of colony from 6?101 to 6?106 were prepared.The bacteria were injected in the tibia after an area of bone defect was made.The inoculated lesions were assessed for changes in radiological and bacteriological parameters at 3 weeks after infection.[Results]Development of significant histological and radiological signs of infected bone defect required an inoculum of at least 6?105 CFU/5 ?l.[Conclusion]These results suggest that strain staphylococcus aureus(ATCC 29213) induces the development of chronic rabbit tibial infection with bone defect,and that this model may be applied to identification of virulence factors in studies of posttraumatic osteomyelitis.

ObjectiveTo explore the influence of gender,age and types of peer acceptance on the ability of theory of mind among rural parent-absent children.Methods 312 rural parent-absent children participated in the study (including 162 boys,150 girls; 102 members of 8 year-old,119 members of 9 year-old,and 91 members of 10 year-old).Their ability of theory of mind and types of peer acceptance were examined by the 2nd-order False-beliefs Tasks and Peer nomination.The date were analyzed by Multivariate analysis of variance (ANOVA),LSD checkout and Simple effect analysis.ResultsThere were statistically significant effects on ages in theory of mind,types of peer acceptance ( F=4.57,P=0.011 ; F =3.82,P =0.005 ) and the interaction among gender,ages and types of peer acceptance(F=3.20,P =0.042; F =2.50,P =0.043 ).The least significant different(LSD) assay of the ability of theory of mind age and types of peer acceptance shows:there were statistically significant lies in the divergence of age 8 and age 9 group,and also in age 9 and age 10 group,(I-J =-0.51,P =0.016;I-J =- 0.90,P =0.000 ).In the same way,there were also statistically significant lies in the divergence of the ability of theory of mind performance-popular and rejected ( I-J =1.05,P =0.001 ) ; popular and neglected ( I-J =0.84,P =0.003 ) ; popular and controversial( I-J =1.03,P =0.002) ; rejected and average ( I-J =- 0.66,P =0.02 ) ; controversial and average ( I-J =- 0.64,P=0.034).Results of simple effect shows:there were statistically significant lies in the gender divergence of the 9 age group (F =4.98,P =0.026),the age divergence of girls (F =7.50,P =0.001 ),the gender divergence of controversial groups (F=5.76,P =0.017 ),the peer acceptance divergence of boys(F=4.97,P =0.001),and also the peer acceptance divergence of girls(F =2.54,P =0.04).Conclusion There is substantial connection between the ability of theory of mind of rural parent-absent children and ages and types of peer acceptance.

Objective To investigate the mRNA expression of CC Chemokines, including RANTES (regulated upon activation, normal T cell expressed and secreted), monocyte chemoattracctant protein-1 (MCP-1), monocyte chemoattracctant protein-3 (MCP-3) and macrophage inhibitory protein 1? (MIP-1?), in peripheral blood mononuclear cells (PBMCs) of patients with chronic urticaria, their mutual correlation, and the relationship between the expression level of CC chemokines and the serum level of IgE and eosinophil cationic protein (ECP) in the patients. Methods Reverse transcription-polymerase reaction (RT-PCR) was applied to semiquantitatively analyze the mRNA expression of RANTES, MCP-1, MCP-3 and MIP-1? in PBMCs from 31 patients with chronic urticaria and 22 healthy subjects. Results The mRNA expression of RANTES, MCP-1, MCP-3 and MIP-1?was significantly higher in the patients than those in the normal controls (P 0.05). In the patients, the mRNA expression of RANTES negatively correlated with the serum level of IgE and ECP (P

Objective To investigate the clinical and imaging features of cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy(CARASIL).Methods Clinical data of a Chinese Mongolian patient with CARASIL were analyzed retrospectively and pedigree investigation was carried out in the family.Results The proband's parents were cousin and her brother was a patient with CARASIL too.The patients had onset at 25 and 23 years old,respectively.Clinical manifestations included cerebral stroke,progressive motor and mental deterioration,seizures,alopecia,and ocular fundus arteriosclerosis.No common risk factors of cerebral stroke were found in the family.Brain MRI showed bilateral diffuse cerebral white matter lesion with multiple infarcts and O'Sullivan sign.Cervical vertebral MRI showed multiple protrusion of intervertebral disc and significant retrogression.Conclusions CARASIL is clinically characterized by young-age-onset cerebral stroke,cerebral arteriosclerosis,alopecia,cervical and lumbar spondylopathy.MRI shows multiple cerebral infarcts,leukoencephalopathy and retrogression of intervertebral disc.

Objective To develop an alignment technique based on the movement of body gravity center. Methods As join forces in the system of balance is zero, the position of body gravity center can be calculated by body gravity which is taken from weight sensors, by the special software. Meanwhile, the position of body gravity will be sent to control unit, which can be transformed to driving signal of motor. The sliding table with laser, linked to motor, can make pursuit movement following with body gravity. A precise alignment can be made as the movement of body gravity. The balance function test is also used to make an assistant estimate for the alignment. Results and Conclusion An alignment technique has been developed for the fit of prosthesis and orthotics.

Objective To investigate the incidence and influencing factors of healthcare-associated infection (HAI) in inpatients with nasopharyngeal carcinoma during radiotherapy period.Methods The occurrence of HAI among patients with nasopharyngeal carcinoma in a tertiary first-class cancer hospital in Jiangsu Province between July 2012 and June 2014 were analyzed retrospectively.Results A total of 1 396 patients were investigated,the incidence of HAI was 2.29%,case incidence of HAI was 2.44%.The most common infection site was oral mucosa (n =24, 70.59%),and most infection occurred 2-4 weeks after the start of the radiotherapy.A total of 38 pathogenic iso-lates were isolated,24 (63.16%)were gram-positive bacteria,12 (31 .58%)were gram-negative bacteria,and 2 (5.26%)were fungi.Incidences of HAI were high in patients >50 years old,with chemotherapy,length of hospital stay>60 days,and used at least 2 kinds of antimicrobial agents (all P <0.05).Conclusion Prevention and control of HAI in patients with nasopharyngeal carcinoma during radiotherapy period should be strengthened,especially for the elderly,patients with chemotherapy,long length of hospital stay,and extensive use of antimicrobial agents.

Objective To explore the effects of electro-acupuncture combined with surface gastric pacing on gastrointestinal dysfunction for patients with spinal cord injury (SCI).Methods Seventy-five SCI patients with gastrointestinal dysfunction were divided randomly into an electro-acupuncture group (group A),a gastric pacing treatment group (group B) and a group for which electro-acupuncture was combined with gastric pacing (group C).There were 25 cases in each group.Members of group A were given 30 minutes of electro-acupuncture per day ; those of group B had 30 minutes of gastric pacing treatment twice per day ; group C was provided with both 30 minutes of electro-acupuncture and one 30-minute gastric pacing treatment per day.All of the interventions lasted ten days.Before and after the treatment,all patients were assessed using a clinical symptoms score and with electrogastrograms,and any adverse effects were observed.Results There was a significant improvement in upper abdominal pain and epigastric discomfort,bloating and early satiety,nausea,vomiting,as well as belching and loss of appetite in each group after treatment.Before treatment there was no significant difference in the average clinical symptom scores of the three groups.After treatment the values had decreased,and those of group C were significantly lower than group A or B.The average scores of groups B and A were not significantly different.The electrogastrogram results showed than after treatment there was significant improvement in N％ and T％ in groups A and B,and also significant improvement in N％,B％ and T％ in group C compared to before treatment.Group C's improvements were all significantly greater than those observed in groups A and B.Conclusion Electro-acupuncture or gastric pacing alone can give some improvement in gastrointestinal function and its electrophysiological indicators,but their combined effects are better than when either is used alone.
