[Objective]To compare the fixation effects of cannulated compression screws and dynamic hip screws.[Method]From July 2000 to December 2006,152 old patients with intertrochanteric hip fracture were fixed with cannulated compression screws(n=68) and dynamic hip screws(n=84).They were followed up and their complete clinic data were obtained.A retrospective comparison was made between the two differet fixation devices in terms of operation time,blood loss,intraoperative and postoperative complications,functional recovery one year postoperatively and treatment expenses.[Result]The differences in operation time,blood loss between 2 groups had statistical significance(P0.05) for the Evans types Ⅰ,Ⅱ patients,but had statistical significance(P

Objective To discuss the surgical method of resection of petroclival tumors used temporal base transtentorial approach.Methods Analyzed 26 cases of petroclival tumors.All of them were surgically treated under intraoperative neurophysiological monitoring by temporal base transtentorial approach.Firstly the supratentorial part of tumors were resected by pieces,and then the tentorium was cut open,in order to resect residue of the subtentorial part of tumors.This surgical maneuver was applied to reduce the retraction to surrounding vessels,nerves and brain stem,as well to protect important structures and to finally achieve radical removal of the tumors.The efficacy and complications were observed.Results Among 26 cases,19 cases (73.1％,19/26) achieved total removal,5 cases (19.2 ％,5/26) achieved subtotal removal and 2 cases (7.7％,2/26) achieved great partial removal.There was no surgery-related death.Eleven cases suffered from partial neurological deficit.All cases were followed up for 3 months to 4 years,3 cases underwent complete recovery,4 cases underwent partial recovery,and 4 cases underwent permanent deficit.Conclusions Using temporal base transtentorial approach to resect petroclival tumors is convenient,applicable,safe and with minimal injury and with high proportionality of total resection.Under intraoperative neurophysiological monitoring,this approach may be an ideal choice for surgical treatment of these tumors.

Objective To study the expression of P57kip2 and its clinical significance in hilar bile duct adenocarcinoma.Methods The expressions of P57kip2 in hilar bile duct adenocarcinoma tissues (37 cases) and normal bile duct tissues (32 cases) were determined by immunohistochemical SP methods.The relations between the expression levels of P57kip2 with clinicopathologic parameters were analyzed.Results The positive rate of P57kip2 was 43.2％ (16/37) in bile duct adenocarcinoma,while it was 87.5％ (28/32) in normal duct tissues (P ＜0.01).The expression level of P57kip2 in adenocarcinoma showed no significant association with gender,age or CA19-9 level (P ＞0.05),but they were significantly related with lymph node metastasis,invasion and degree of differentiation (P ＜ 0.05).Conclusions P57kip2 is associated with the occurrence and development of hilar bile duct adenocarcinoma.It may play an important role in invasion and metastasis of hilar bile duct adenocarcinoma.The P57 protein can be used as an index to diagnose hilar bile duct adenocarcinoma.

In this study, the effects of blood glucose and blood pressure on the compliance of large and small arteries were investigated. The results showed that arterial compliances of both large and small arteries were decreased in patients with diabetes mellitus. In non-diabetic patients with well controlled blood pressure, the compliance of small arteries was markedly improved. These results suggested that both blood glucose and blood pressure affected arterial compliance.

Aim To explore the hemodynamic change of elderly isolated hypertension(EISH). Methods Color doppler ultrasonography were applied to examine thirty EISH patients and twenty eight elderly healthy subjects. The left ventricular systolic function as well as hemodynamic parameters were measured. Results The indices of left ventricular systolic function in EISH group such as SV,CO,EF and CI were obviously higher than those of control group(P<0.05),Linear relevant analysis show that pulse pressure was remarkable related to SV,CO,EF and CI in EISH group,with r value 0.43,0.56,0.46,0.45 respectively.Conclusion EISH patients apparently had ventricular systolic dysfunction and hemodynamic abnormality. Pulse pressure may be associated with development of sysytolic dysfunction.

Objective To investigate the operational timing and manner for the digestive tract reconstruction after Hartmann procedure and the prevention for the postoperative complications in the patients with left colorectal cancer.Methods The data of twenty-four cases with digestive tract reconstruction were analysed retrospectively containing the cause of Hartmann procedure for left colorectal cancer,preoperative evaluation of the digestive tract reconstruction,operation timing,operation manner,postoperative complications and length of hospital stay and so on.Results Three of 24 patients gave up the digestive tract reconstruction due to the results of their distant metastasis detection in the preoperative evaluation.As a commonly manner of digestive tract reconstruction,rectum-sigmoid colon or sigmoid-descending colon end-end anastomosis was used for 17 patients.Meanwhile,ascending colon-sigmoid colon end-side anastomosis was used for 4 patients.The incidence of postoperative complications was 14.29 ％ (3/21),and the mean time of postoperative hospital stay was 10.5 days.Conclusions In patients undergoing Hartmann procedure for left colorectal cancer,adequate assessment of the tumor recurrence and metastasis is necessary.In addition,the optimal timing of surgery should be selected after completion of chemotherapy,and operational manner should be determined by the situation of intraoperative exploration.

OBJECTIVE: To evaluate the applicative value of multimodal navigation combined with intraoperative magnetic resonance imaging system in the treatment of complex lesions of middle skull base. METHOD: Nineteen consecutive patients undergoing complex lesions resection using multimodal microscopic navigation combined with iMRI were included. Preoperative radiological images were imported into navigation planning system, based on which approach and microsurgical window were designed. Transcranial approach and extracranial approach(include trans-oral-nasal-sphenoidal approach and transsphenoidal approach) were performed in our series. After presumptively total resection were finished, intraoperative magnetic resonance (iMRI)were performed, followed by navigation images updating, and continuing resection if necessary. RESULT: iMRI scan were performed from 1 time to 2 times. In 5 cases with residual seen on iMRI scan, continued resection were carried on in 2 of them. There was no iMRI-associated complications. CONCLUSION Microscopic-based neuronavigation, in combination with intraoperative magnetic resonance, could provide objective basis for resection, and improve the safety level of tumor resection.

Cross-talk of intracellular signaling pathways that share common components (hubs) is organized in form of a bow-tie network topology.Signaling cross-talk is functionally pleiotropic for target genes regulation, resulting in functional redundancy, synergism and antagonism, which should be precisely controlled to prevent signaling 'leaking' or 'spillover'.Thus, the biological system has evolved multiple insulating mechanisms to achieve stimulus-specific response that maintains intracellular homeostasis.The insulation mechanism of signaling cross-talk suggests: (1) the functional duality of cross-talk molecules that determine cell fate requires selectively targeting dysregulated cross-talk molecules while protecting the normal ones from off-target or unintended effects, and we propose them as the targetable cross-talk molecules;(2) cross-talk molecules are usually carried on the macromolecular complex as their functional platforms, thus the structural plasticity of conformational changes at the interaction surface of cross-talk molecules asks for intensive work on the relationship study between drug binding and biological activity, which we propose as the accessible cross-talk molecules.Therefore, signaling cross-talk and its insulation mechanism play instructive leading roles in resolving the bottlenecks of current drug R&D and improve the clinical outcome.

This study examined the effect of different b values on diffusion-weighted MR imaging (DWI) of human prostate by using single-shot spin echo echo planar imaging (SE-EPI) sequences, observed the normal appearances and measured apparent diffusion coefficient (ADC) values in anatomical regions of normal prostate. Twenty-four healthy volunteers (mean age: 32 y) were studied by using a 1.5T system with a phased array surface multicoil. Two kinds of single-shot SE-EPI sequence were used to perform DWI in the prostate in volunteers, with five b values being 0, 30, 300, 500 to 1000 s/mm(2). The image quality with different imaging parameters was analyzed and the ADC values in anatomical regions of normal prostate were measured. DWI of prostate was successfully obtained in all volunteers. The images were of good quality, without artifacts containing pixels within the prostate. The contrast was good between the different anatomical regions of the prostatic gland, i.e., the peripheral zone (PZ), which exhibited higher signal intensity, and the central gland (CG). Signal intensity contrast was related to the magnitude of b values. The ADC values in PZ and CG were (1.27+/-0.22)x10(-3) mm(2)/s and (1.01+/-0.17)x10(-3) mm(2)/s, respectively. The ADC values were found to be significantly higher in PZ than in CG (P<0.05, paired t-test). Significant differences were found between the slice-selecting component and both the read-out and phase-encoding components of the ADC values. It is concluded that SE-EPI is a suitable DWI sequence for human prostate. The contrast between PZ and CG is good when b values are low, while the diffusion and ADC values are accurate when b values are high. ADC values are higher in PZ than in CG in normal prostate. Diffusional anisotropy is present in normal prostatic tissue.
