Objective: The aim of this study was to develop and assess the computer-assisted fabricated individual titanium mesh technique applied for reconstruction of fractured orbital walls to correct post-traumatic enophthalmus and diplopia. Methods: Twenty patients (12 males and 8 females) were inclu-ded in this study. All of patients suffered from unilateral impure orbital fractures. Group A included 8 patients who were reconstructed for the fractured orbit with computer-assisted fabricated titanium mesh technique. Group B had 12 patients treated with traditional methods (titanium meshes in 2, autogenous bone grafts in 7 and Medpor implantation in 3). CT data of group A was input into a image software to rebuild a 3-D orbit and then mirror the unaffected side onto the affected side to replace the demolished orbit. A resin model of the reshaped orbit was then produced and was used to develop custom-fabricated titanium mesh for repair of the fractured orbital wall. The fabricated mesh was used in operation to reconstruct the orbital wall. Treatment was assessed in comparison with traditional way by means of clinical examinations and CT measurements. Results: The difference between pre-operative and post-operative enophthalmos: the mean value of group A was 2.6 mm, group B was 2.0 mm;the difference between the pre-operative and post-operative enlargement volume of traumatic orbit: the mean value of group A was 4.3 mL, group B was 3.7 mL; Index of Medial orbital wall of both groups was 100% and Index of inferior wall reconstruction of group A was 84.7%, group B was 53.3%; The mean depth of implants of group A was 31.2 mm, of group B was 28.3 mm; Improvement of diplopia of group A was 1.5 quadrants, that of group B was 1 quadrant. There were no infection, gaze restriction, or graft extrusion in all patients after operation. Conclusion: Computer-assisted fabricated titanium mesh technique could provide more accurate orbital reconstruction and improve the correction of enophthalmus and diplopia.

Objective To evaluate the therapeutic effectiveness of postoperative hemorrhage of cholejejunal or pancreato - jejunal anastomotic stoma after pancreato - duodenectomy by the way of fibercholedochoscopy. Meth- ods The drainge tube was extracted out of choledochojejunal anastomotic stoma. And fibercholedochoscopy was in- serted in fistula to affirm hemorrhagic position of choledochojejunal or pancreato - jejunal anastomotic stoma. And then local coagulation and microwave solidifying was proceeded with. Local spray of Galla - chineses compound solution was performed for hemostasis. Results We succeeded in hemorrhage of four choledochojejunal and six pancreato - jejunal anastomotic stoma One failed for frequent hemorrhage in pancreato - jejunal anastomotic stoma. Conclu- sion Fibercholedochoscopy is the first selective and effective method in the diagnosis and treatment of postoperative hemorrhoge of pancreato - jejunal or choledochojejunal anastomotic stoma after whipple operation.

Objective To explore the difference of the tremor of Parkinson's disease(PD) in early stage and physiological tremor by tremor analysis.Methods 14 patients with PD(group PD) and 9 cases of physiological tremor(group physiological tremor) were studied.The surface electrode of the accelerometry(Acc) was pasted at the end of certer-metacarpal of back of hand.At the same time,surface electrodes of electromyography(EMG) were pasted on the forearm flexors and extensors.The tremor graphices and myoelectric activities were recorded in 30 s with and without 1000 g bearing respectively.Tremor frequency and related myoelectric activities were analysed.Results Acc record: The main manifestations were static tremor and tremor frequency was no significant difference when with and without loading in group PD.In group physiological tremor,the main manifestations were posture or active tremor.With loading,the tremor frequency was significant reduced(P

Twenty five serotypes of Bluetongue virus (BTV) have been identified worldwide. Rapid and reliable methods of virus universal detection are essential for fighting against bluetongue (BT). We have therefore developed and evaluated a pair of primers which can detect various serotypes of BTV by RT-PCR. Analysis of the viral protein 7 (VP7) and the non-structural protein (NS1) gene from different serotypes of BTV by DNAstar showed that the 5' end of the NS1 gene is the most conserved region. The primer pairs (P1 and P2) were designed based on the highly conserved region of NS1. The novel primers were evaluated by detecting BTV serotypes 1, 3, 5, 8, 10, 11, 21 and 22. The specificity of the primers was estimated by comparing to gene sequences of viruses published in GenBank, and further assessed by detecting BTV serotype 1-12 and Epizootic hemorrhagic disease virus (EHDV) serotype 1-4. The sensitivity and repeatability of PCR with the novel primers were evaluated by successfully detecting the recombinant plasmid pGEM-T121 containing the diagnosed nucleotide sequence. Our results suggest that these unique primers can be used in high throughout and universal detection of the NS1 gene from various BTV serotypes.

Objective To detect the activity of α1 antitrypsin(AAT) with initial velocity of enzymatic reaction in order to detect the activity of samples in the process of separating and purifying plasma protein ,chromogenic substrate assay was optimized.Methods The effect of trypsin concentration and reaction time on enzymatic reaction was acquired by the kinetic monitoring mode of the microplate reader .Initial velocity was calculated to confirm the largest concentration of trypsin which was saturated by substrate .AAT was incubated with trypsin and absorbance produced by enzymatic reaction of remaining trypsin and substrate could reflect the activity of AAT .A standard curve was established with △D fitting with the activity of AAT standard.The activity of related samples was detected and the precision and accuracy of the method were evaluated . Results Trypsin concentration was 0.0625 mg/ml.Within 20 minutes, enzymatic reaction was with initial velocity .The range of the standard curve was 200-1200 IU/ml.Correlation coefficient was more than 0.99.The activity of Cohn Ⅳ, samples of pre-processing and elution were (720.59 ±18.63), (601.84 ±19.18),and (568.09 ±24.83)IU/ml, respec-tively.The relative standard deviation was less than 10%. Sample recovery rate was 90%-110%.Conclusion The optimized chromogenic substrate assay greatly improves accuracy and precision .The method can be used for the detec-tion of AAT activity of samples in laboratories and workshops .

Objective:To review and compare the clinical features and treatment outcomes of oral and maxillofacial space infection (OMSI)between diabetic and non-diabetic patients.Methods:Clinical data of 43 diabetic patients with OMSI(simultaneoustly treated by blood sugar control)and 84 of non-diabetic patients with OMSI were reviewed,the clinical features and treatment outcomes were compared.Statistical analyses were conducted by T test,the chi square test and variance analysis.Results:Diabetic patients with OM-SI were older(P =0.000),had more spaces involved concurrently(P =0.035 )and had higher blood sugar at presentation(P =0.000).There was no significant difference between groups about the use and change of antibiotics,the incision times,hospital stay durition and the incidence of the complications.Conclusion:The prognosis of the diabetic patients with OMSI under the strict control of the blood glucose concentration has no significant difference from the non-diabetic patients with OMSI.Diabetic patients with OMSI have older age and more spaces involved,and special attention should be paid.

Plasma products are considered to be special medicinesderived from healthy human plasma .During 1980′s, events of transmission of human immunodeficiency virus through plasma products were frequently reported .Since then, ensuring the viral safety of plasma products has raised great concerns all over the world .So far, with decades of effort , most countries in the world have established rigorous systems with preventive measures to ensure the viral safety of plasma prod -ucts.These measures include control of source plasma , validated inactivation/removal of infectious agents , the adherence to current good manufacturing practices .Nevertheless , new infectious agents which may be threats to viral safety require continuous studies on appropriate countermeasures .
