[Objective]To explore a new technique of prefabricating internal plate.[Method]Three-dimensional reconstruction of the well-liking shinbone was performed by MSCT scanning and the length and shape of the catagmatic shinbone for operation was measured on well-liking shinbone.The shinbone curve was depicted using a self-designed skeletal curve-depicting.Then shape of the material for internal fixation was determined.[Result]The length and shape of the shinbone curve was accurately measured.The physiological curve of the shinbone was depicted.Then shape of the material for internal fixation was determined.[Conclusion]Three-dimensional well-liking shinbone reconstruction with MSCT and measurement facilitates the determination of the optimal length and shape of the internal fixation material to enhance the attachment between the material and the bone surface and consequently the therapeutic effects.One case's length and shape of internal fixation was dissatisfactory for hyperplasia of bone.But the length and shape of internal fixation has basal shape.

BACKGROUND:The treatment of displaced acetabular fractures consists of formal open reduction and internal fixation.However,extensile exposure can lead to a lot of complications Percutaneous screw fixation for acetabukar fractures can decrease these complications Recently developed fluoroscopic-based computerized navigation technology not only allows the surgeon to achieve maximum accuracy of screw fixation but also significantly reduce radiation exposure time.OBJECTIVE:To evaluate the clinical application of the fluoroscopic-based computerized navigation system for percutaneous screwing for acetabular fractures.METHODS:A total of 18 adult patients with 20 non-displaced and displaced acetabular fractures were treated with percutaneous screw fixation under the guidance of a fluoroscopy-based navigation system.All acetabular fractures were acetabular anterior column fractures and posterior column fractures,which were fixed by varied hollow screws Static muscle contraction and limited active and passive motion were performed at 2 days,and weight-bearing exercise was performed at 4 weeks after operation.The time of screw implantation,screw position deviation,screw biocompatibility,as well as adverse effect after screw implantation was observed.In addition.d'Aubigne and Postel scoring was used in follow-up.RESULTS AND CONCLUSION:A total of 30 acetabular screws were inserted.The average operation time for per screw was24.1 minutes from the image acquisition to wound closure.The average fluoroscopic time for per screw was 27.6 seconds.Compared to the final position of the screw,the average wire tip error was 1.5 mm and the average trajectory difference was2.25°.One patient sustained a transient femoral nerve palsy which was attribute to reduction clamp inserting from the use of the limited open reduction method rather than screw fixation itself and resolved 2 months after the operation.No evidence was noted of secondary displacement of the fragment or screw failure Using the rating system of d'Aubigne and Postel,13 patients had excellent results,4 patients had good results,and 1 patient had a fair result.The excellent to good rate was 94%All results demonstrated that percutaneous screw fixation of acetabular fractures with fluoroscopy-based navigation can produce excellent results in selected patients with non-displaced and displaced fracture amenable to closed or limited open reduction,which becomes a safe and effective alternative to traditional open reduction and internal fixation for the treatment of certain acetabular fractures.

Objective To evaluate the acute side effects and efficacy of three dimensional conformal radiotherapy(3DCRT) combined with chemotherapy(CT) for locally advanced non small cell lung cancer(LANSCLC). Methods From Sept. 2000 to Dec.2001,24 patients with LANSCLC were treated with three dimensional conformal radiotherapy combined with chemotherapy navelbine+cisplatin NP. Results The overall response rate(CR+PR)was 91.7% for the primary tumor, and 100% for metastatic mediastinal lymph nodes.The leucopenia rate was 95.8%(54.2% grades 3,4). Acute radiation esophagitis occurred in 54.2% of patients(Grades 1,2). Acute radiation pneumonitis was observed in 12.5% of patients (Grades1,2). Conclusions 3DCRT combined with CT is well tolerated in most patients with LANSCLC. Its early responses are milder than the conventional radiotherapy combined with chemotherapy . Remote results await further follow up.

Objective To investigate the effect of time from myocardial infarction (MI) onset to percutaneous coronary intervention (PCI) on plasma matrix metalloproteinases (MMPs) level and left ventricle (LV) remodeling in patients with acute ST-segment elevation myocardial infarction of anterior wall,and the relationship between MMPs and left ventricular remodeling.Methods All patients with anterior wall STEMI undergoing PCI were divided into early PCI group (PCI within 18 h after MI onset) and delayed PCI group (PCI between 2 and 3 weeks after MI onset).Plasma MMP-2 and MMP-9 activities were assayed on admission,and at 2 days,1 week after admission.One-year follow-up was finished after PCI.Left ventricular end-diastolic volume (LVEDV),left ventricular end-systolic volume (LVESV) and left ventricle ejection fraction (LVEF) were measured by echocardiography at baseline and one year later to elucidate the effects of time from onset to PCI on LV remodeling and the relationship between MMP-2,-9 levels and LV remodeling.Results The MMP -9 activity at 2 days after myocardial infarction was lower in early PCI group than in delayed PCI group [(46±26)μg/L vs.(66±40) μg/L,P=0.000].The changes in LVEDV and LVESV (△LVEDV and △LVESV) were lower and the change in LVEF (△LVEF) was higher in early PCI group than in delayed PCI group [(10.9±6.2) ml vs.(15.0±6.0)ml,(-1.1±5.7) ml vs.(2.9±4.6) ml,(5.5 ±4.0) ％ vs.(3.8±3.4) ％,P=0.000,0.000 and 0.015].MMP-9 had positive correlations with △LVEDV and △LVESV,and a negative correlation with △LVEF at admission and after 1-year follow-up (r=0.32,0.36 and-0.29,respectively,P=0.000,0.000 and 0.001).Conclusions MMP-9 activity at admission is correlated with LV remodeling and LV function.Early PCI can reduce MMP-9 activity and improve LV remodeling after myocardial infarction.

Objectives To evaluate the performances of transcranial Doppler (TCD) and vessel-encoded arterial spin labeling MRI perfusion imaging (VE-ASL) in the evaluation of collateral circulation of cerebral arteries. Methods Thirty patients with unilateral ICA or MCA stenosis diagnosed by TCD and carotid duplex ultrasound and confirmed by MRA underwent VE-ASL. Peak systolic velocity (PSV) of bilateral MCA in the same depth, distal to the stenosis site, was recorded. Cerebral blood flow (CBF) in bilateral MCA territories was measured by VE-ASL. The detection rates of collater-al flow using TCD and VE-ASL were compared. Results TCD revealed that PSV in the ipsilateral and contralateral MCA were (31.6 ± 10.5) cm/s and (83.1 ± 9.2) cm/s, respectively. VE_ASL revealed that CBF in the ipsilateral and contralateral MCA territory were (22.5±9.8) mL·min-1·100g-1 and (31.7±8.3) mL·min-1·100g-1, respectively. The PSV ratio of the ipsi-lateral/contralateral MCA was significantly lower than the CBF ratio of the ipsilateral/contralateral MCA(0.37 ± 0.173 vs. 0.66±0.141, P=0.001). The detection rates of collateral flow using TCD were lower than those using VE-ASL. The detec-tion rate was 26.7% vs. 70% on TCD vs. VE-ASL in anterior collateral circulation (P=0.001), was 16.7% vs. 60% (P<0.001) on TCD vs. VE-ASL in posterior collateral circulation. The total display rate of collateral flow was 36.7%vs. 86.7%on TCD vs. VE-ASL (P<0.001). Conclusions TCD is inferior to VE-ASL in evaluating the collateral circulation because of the limitations including the anatomical variations of the circle of Willis and formation of leptomenigeal anastomoses.

Objective To study the differences in retinoic acid receptor γ(RARγ) mRNA expression levels in blood leukocytes between antipsychotic-free and antipsychotic-naive schizophrenic patients and healthy control,especially in different genders. Methods Forty-three acute schizophrenic patients who were antipsychotic-naive or antipsychotic-free for at least three months (male = 34, female = 9) and 39 age- and sex-matched healthy subjects (male =25 ,female = 14) were included for blood leukocytes expression of RAR γ mRNA ,using real-time PCR technique. Results Kolmogorov-Smirnov Z analysis showed a significant increase of RARγ mRNA (P =0.041) level in blood leukocytes of pooled schizophrenic patients(0. 027 ± 0. 003) than in the healthy subjects (0. 020 ± 0.002). The elevation was mainly found in the female patients (0. 030 ± 0.003). Within-sex analysis showed that the female schizophrenic patients showed a trend increase (P = 0. 166) of RAR γmRNA expression compared with the male patients (0. 026 ± 0. 001) and exhibited greater RARγ mRNA expression (P = 0. 014)when compared with the female healthy subjects(0. 018 ±0.004). Conclusions The present findings showed an abnormal expression of leukocyte RARγ mRNA level in antipsychotic-free and antipsychotic-naive schizophrenia especially in the female patients. Blood RARγ markers could add to the diagnosis and individualized pharmacotherapy of schizophrenic patients ,especially the female patients.

Objective To determine attention networks impairmnet in patients with localized brain injury and to examine the characteristics of the impairment.Methods The attention network test was used to compare patients(n=59)with controls(n=53)on the efficiency of 3 anatomically defined attention networks:alerting,orienting,and executive control.Results Firstly,patients with frontal lobe injury showed a significant deficit in the executive network(frontal lobe injury,controls:(143.7±46.6),(91.6±46.4)ms,Z=-4.714,P＜0.01)and also a significant deficit in the orienting network(frontal lobe injury,controls:(71.2±35.2),(55.1±21.8)ms,Z=-2.125,P＜0.05).There was no deficit in the alerting network(Z=-0.901,P＞0.05).Secondly,the orienting network effect was significantly lower in patients with parietal lobe injury((34.9±25.2)ms)than in normal controls((55.1±21.8)ms.Z=-2.418.P＜0.05).However,there were no significant difierences between the other two networks and between the patients and the controls(Z=-1.873,-0.186.P＞0.05).Thirdly,patients with temporal lobe injury showed no deficit in the three networks(Z=-0.037,-1.224,-0.718,all P＞0.05)as well as in overall RT and accuracy(Z=-1.385,-0.699,all P＞0.05).Conclusions These results suggest that there are selective impairments of the orienting and executive networks in patients with the frontal lobe and the parietal lobe injury,while the alerting network is spared.Furthermore,the frontallobe plays a key role in the executive control.meanwhile,the orienting network is closely related with the parietal lobe.

BACKGROUND: Infection following kidney transplantation has become one of the main reasons for graft failure and death of allograft recipients. However, there is not a standard therapeutic scheme for infection following kidney transplantation. OBJECTIVE: To investigate the clinical features and treatment measures of infection, additionally, to increase the cure rate of infection following kidney transplantation.DESIGN, TIME AND SETTING: A retrospectively analysis was performed at the Organ Transplantation Center, the First Affiliated Hospital of Kunming Medical College from February 2006 to February 2008.PARTClPANTS: Eighteen cases of infections in 84 kidney allograft recipients.METHODS: All cases were checked by chest X-ray. Patients who had no significant lung infection symptoms or obvious signs received lung CT scan. Pathogen detection was performed, including hemoculture, urine culture, sputum culture, nose swabs culture, throat swab culture, checking clinically important cytomegalovirus (CMV), EB-DNA and mycoplasma in blood, acid-fast bacilli and eumycete culture in sputum. All cases of pulmonary infection underwent a comprehensive treatment-antiviral drugs, antibiotics and antifungal. Depending on the individual condition and absolute values of lymphocytes and CD4+T cells, the immunosuppressant was adjusted individually. The occurrence time, clinical symptom, auxiliary examination and treatment strategies were analyzed.MAIN OUTCOME MEASURES: The occurrence time of infection and clinical symptoms; imaging manifestation and results of pathogenic detection; selection of antibiotics and immunosuppressant adjustment.RESULTS: Among 18 cases, 11 cases (61.2%) were deceased-donor kidney transplant recipients. Inflection following kidney transplantation occurred in 12 cases (66.7%) within 3 months, and increased to 15 cases (83.3%) within 3-6 months. Of the 18 infection cases, 14 cases (77.8%) had a main symptom of fever. There were 15 cases (83.3%) of respiratory tract infection, including 13 cases (72.2%) of pulmonary infection. Fungal cultivation, especially Monilia, was positive in 6 cases. Three out of the 18 cases (16.7%) died, two of whom had CMV infection. Mixed infection occurred in all cases.CONCLUSION: Infected patients following kidney transplantation present with diversity pathogens, which are dominated by bacteria, fungus and virus. Severe pneumonia combined with CMV infection demonstrates that poor prognosis, fungal and virus infection following kidney transplantation should be given more attention. Combined de-escalation therapy is the main method, and timely adjustment and even discontinuance of immunosupprassive agents is one of the key points in the treatment of infection following kidney transplantation

Objective To explore the effect of age on the fracture healing through bioinformatical analysis of gene ex?pression data in GEO, and to screen critical molecular targets and pathways involved in this process. Methods Through R programming language, we identified different expressed genes between 26/52 week old rats and 6 week old rats in every time points of the experiment (No fracture;3 days, 1 week, 2 weeks, 4 weeks and 6 weeks after fracture). By comparison of these different expressed genes, those genes that may contribute to fracture healing were identified. Function annotation was conducted based on DAVID database and PPI network that was constructed via STRING database. Results Compared with 6 week old rat, 52 week old rat show more different genes at 2, 4 and 6 weeks after fracture as well as more than intact rats. At the time point of 6 weeks after fracture, 26 week old rat present 4 different genes while 52 week old rat present 99 differ?ent genes compared with 6 week old rat. We totally found 99 genes that might play important roles in the process of fracture healing. These genes involved in biological process related to bone healing, immune, inflammatory and etc. Also, two screened gene enriched KEGG pathways were identified: ECM-receptor interaction and Arachidonic acid metabolism. Through the analysis of PPI network, Pcna, Fn1, Casp3 and etc, who present high density connectivity in PPI network, were screened out. Conclusion Pcna, Casp3 and Fn1 and etc might play important roles in fracture healing through affecting ECM-receptor interaction and Arachidonic acid metabolism.
