OBJECTIVETo explore the effects of nano-hydroxyapatite/polyamide 66 (n-HA/PA66) cage on recovering and maintaining lumbar curvature, lumbar heights and fusion rate when used in the transforaminal lumbar interbody fusion.

METHODSFrom February to July 2012, 50 patients with degenerative lumbar disease(lumbar disc herniation in 32 cases and lumbar spondylolisthesis in 18 cases) were treated with transforaminal lumbar interbody fusion using the n-HA/PA66 cage, and their preoperative and postoperative clinical outcomes were analyzed. The patients were followed up for 2, 4, 6 and 8 months after operation, during which the CR and CT film of lumbar vertebra were checked to get relative height of vertebral space, Taillard index,index of lumbar spinal curvature,angle of segmental and full lumbar lordosis. The data were analyzed respectively with pair t-test, analysis of variance or LSD-t-test.

RESULTSAll the patients were followed up, and the duraion ranged from 8 to 13 months, with a mean of 11.32 months. There were significant differences in relative height of vertebral space, Taillard index, index of lumbar spinal curvature, angle of segmental and full lumbar lordosis after surgery, but there were no significant differences in different periods after operation. The fusion time of lumbar ranged from 4 to 8 months.

CONCLUSIONThe n-HA/PA66 cage can recover and maintain lumbar normal stability with higher rate of fusion and less complications.

Objective To establish a simple and sensitive method for the determination of serum copper by spectrophotometry.Methods Nitro-PAPS was used as a coloring agent for serum copper in the presence of surfactants Tween-80 and Triton X-100 and the formed complex was measured by spectrophotometry.Results The maximum absorption wavelength of the complex was 570 nm and the molar absorption coefficient was 7.95?10~4 L/(mol?cm).The lineafity of the method was up to 63.0 ?mol/L and the recoveries ranged from 98.6% to 103.1%.The within-run and between-run CVs were 2.1%-3.3% and 2.7%-3.8%.The method(Y)was compared with an AAS method(X)and a correlation of Y=1.01X -0.27(r=0.998 2)was obtained.A reference interval(x~-?2s)determined with this method on 68 individuals was 9.7-24.1 ?moL/L.Conclusions A simple and sensitive method for serum copper has been established.It may used for the analysis of serum copper in clinical laboratories.

The nitrite-reducing activity of aerobic denitrifying bacterial strain N6-1 was studied. It showed that the nitrite-reducing activity reached the highest at 30℃, 120 r/min, pH 8.5 and C/N ratio 12, using CH3COONa and NaNO2 as the sole carbon source and nitrogen source, respectively. When the initial NaNO2 concentration was 2 g/L, NO2--N was reduced completely after 20 hours cultivation with the reducing rate of 20.3 mg/L?h. There would be no effect on its nitrite-reducing activity in the present of 1.5% NaCl or 1% peptone. The cell concentration could reach 1.2?1011 CFU/mL after 24 hours cultivation in 10 L fermentor.

Objective To explore the changes and clinical significance of levels of serum vascular endothelial growth factor(VEGF)and endostatin in smokers. Methods In a case-control study,levels of serum VEGF and endostatin were determined in 82 smokers with lung cancer,82 pair-matched smokers without lung cancer and 20 healthy non-smokers by enzyme-linked immunoabsent assay(ELISA) or competitive enzyme immunoassay.Results The level of serum VEGF in smokers with lung anncer[(16.1±7.9)ng/ml]was markedly higher than that in the other two groups(both P＜0.01).The level of serum VEGF in smokers without lung cancer was significantly higher than that in healthy non-smokers(P＜0.05).The level of serum endostatin in smokers with lung cancer was significantly higher than that in healthy nonsmokers(P＜0.01),but was not significantly different from that in smokers without lung cancer(P＞0.05),and that in smokers without lung cancer was significantly higher than that in healthy non-smokers (P＜0.05).Notably,the ratio of endostatin to VEGF in smokers with lung cancer(1.3±0.5)was significantly lower than that in the other two groups(both P＜0.01).However.there was no significant difference in it between smokers without lung cancer and healthy non-smokers(P＞0.05).The level of serum VEGF correlated significantly to that of endostatin in smokers both with and without lung cancer(P＜0.01).Conclusions These findings suggest that smoking may result in imbalance of levels of serum endostatin and VEGF leading to tumorigenesis.The ratio of endostatin to VEGF can be used as an early diagnostic indicator for lung cancer in smokers.Periodic determination of levels of serum VEGF and endostatin as well as the ratio of endostatin to VEGF is of clinical importance.

Objective To analyse the management of splanchnic artery aneurysms by open surgery and endoluminal therapy. Methods The clinical data of 10 splanchnic artery aneurysm patients (four male, six female) hospitalised from January 2002 were analysed retrospectively. The average age was (56 ± 13) years (28 - 74). Surgical or endoluminal treatment for six cases of splenic artery aneurysms or pseudoaneurysms were applied, among which multiple splenic artery aneurysms was found in one, and aberrant aneurysms at the proximal section of the splenic artery originating from a spleno-mesenteric trunk was found in three, splenic artery pseudoaneurysm in one and single aneurysm with normal splenic artery in anatomy in one. Besides, there were two superior mesenteric artery aneurysm, one of tuberculous celiac artery pseudoaneurysm and one renal artery aneurysm. Results The tuberculous celiac artery pseudoaneurysm was successfully managed by deploying a stent-graft endoluminally. One case was converted to open surgery after the splenic artery aneurysm was only paitially covered by a stent-graft. The other 8 cases were successfully treated by open surgery. All of the operations are successful. All patients were followed up from three months to six years, during which no death or other severe complications occurs. Conclusions The splanchnic artery varies from one to another anatomically. Preoperative CT scan or digital substraction angiology are helpful for the diagnosis of the splanchnic arterial aneurysms and choosing an appropriate management. Conventional open surgery is effective and reliable, while endoluminal therapy is a minimally invasive alternative.

Objective To explore the relationship of the ratio of plasma adrenomedullin(AM)and endothelin-1(ET-1)with serum concentration of neuron-specific enolase(NSE)in full-term neonates with hypoxic-ischemic encephalopathy(HIE).Methods Plasma concentrations of AM,ET-1 and serum NSE from 32 full-term neonates with HIE were detected by radioimmunoassay(RIA)on the 1,3 and 7 d after parturition,30 neonates in the corresponding periods in our hospital were employed as controls.The infants with HIE were divided into mild,moderate or severe group in terms of diagnostic standard of HIE.Results 1.Plasma concentrations of AM and ET-1 in newborns with mild,moderate or severe HIE were significantly higher than that of control group at 1 d after life with a decline from 3-7 d(Pa

Objective To explore the surgical management for arterial diseases. Methods The clinical data of 86 cases of arterial diseases were analysed retrospectively. These cases included:3 cases of thoracic aortic aneurysm,2 cases of descending aortic dissection with rupture and aneurysm formation,2 cases of abdominal aortic dissection with false aneurysm,1 case of abdominal aortic aneurysm(AAA)with duodenojejunal fistula and GI bleeding,5 cases of ruptured AAA with shock, 3 cases of traumatic rupture of abdominal aorta,21 cases of AAA combined with unilateral or bilateral iliac aneurysms,6 cases of iliac aneurysms,9 cases of popliteal aneurysms,21 cases of false aneurysm of iliac or popliteal artery,1 case of rupture of junction of subclavian and vertebral artery with false aneurysm,3 cases of rupture of subclavian artery with false aneurysm,2 cases of aneurysm of carotid artery and 7 cases of false aneurysm of carotid artery. Prosthetic vascular graft was performed in 71(cases),autologous vein graft in 3 cases and suture(repair) of arterial rupture in 12 cases.Results Operative (mortalty) was 3.5%(3/86)in this series.Seventy-one cases were followed-up for 1 month to 5 years, the results showed that all the patients were alive and well.Conclusions In the(management) of(appropriate) aortic diseases, the use of endoluminal technique is simple, microtraumtic, safe and has few complications. It also can shorten the hospital stay of the patient. Endovascular technique should be the first choice for patients with aortic diseases.
