Objective To compare the short-term effect of Docetaxe and Irinotecan combined with Xeloda in treatment of end stage gastric cancer.Methods 65 patients with advanced gastric cancer were randomly divided into two groups.33 patients in group A received Docetaxe plus Xeloda and 32 patients in group B received Irinotecan plus Xeloda.At least two treatment cycles were completed.Results The overall response rate is 54.54%(A) and 53.13%(B),and the median progression-free survival was 6.1 months and 6.2 months.Patients in group A experienced more anemia,and patients in group B,diarrhoea.Conclusion The effects of Docetaxe or Irinotecan combined with Xeloda in the treatment of advanced gastric cancer are comparable and well tolerated.

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.

OBJECTIVETo evaluate the results of nephron-sparing surgery (NSS) for renal tumors.

METHODSA retrospective analysis was performed for the clinical data of 66 patients who were affected by renal tumors and treated with NSS.

RESULTSAmong 66 cases, 63 were treated with partial nephrectomy and 6 with enucleation. The renal vessel was clamped in 45 cases intraoperative. The histological subtypes included clear cell carcinoma in 40 cases, papillary renal cell carcinoma (RCC) in 2 cases, chromophobe RCC in 2 cases, angiomyolipoma in 24 cases, and adenoma in one case. Surgical margins were negative in all cases. Seven patients had postoperative complications and no perioperative acute renal failure occurred. Among 44 cases with renal cell carcinoma, 42 were followed for mean 55.4 months. The overall and disease-free 5-year survival rates were 97.3% and 90.7%, respectively.

CONCLUSIONNSS is a effective and safe operation for selected patients with renal tumors, providing functional advantage gained by the maximal preservation of unaffected renal parenchyma without sacrificing cancer control.

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 observe the effect of movement exercise combined with electroaeupuneture on the expression of Nestin in the hippocampus dentate gyrus (DG) after cerebral ischemia-repeffusion.Methods Fifty- four Wistar rats were used and randomly divided into a control group (Group A),an exercise training group (Group B),and an exercise training combined with electroacupuncture group (Group C).The middle cerebral arteries (MCA) of all the rats were occluded for 1 h,followed by reperfusion for 7,14 and 21 davs.Immunohistochemistry method was used to detect the expression of Nestin in the hippoeampus dentate gyrus.Results The number of Nes- tin-positive cells peaked in DG in all groups on the 7th day after cerebral isehemia-reperfusion.The number of Nes- tin-positive cells in DG ipsilateral to the ischemia-reperfusion lesion were significantly more than those in the opposite side at various time points (P

Aiming at the characteristics of telemedicine service,we summarized our telemedical consultation work during 2006-2008.We believed that telemedical consultation from big hospitals are very important in maintaining physical and moral health conditions and treating severe sickness of grassroots officers and soldiers,it can also play active roles in the construction of basic army unit hospitals.

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.

As a kind of commonly used traditional Chinese medicine, ginseng has a high reputation at home and abroad. The research of ginseng has been expanded to medicine, pharmacy, biology, food science and other fields, with great achievements in recent years. Ginseng contains ginsenosides, volatile oil, carbohydrates, amino acids, polypeptides, inorganic elements and othser chemical constituents. Each component has extensive physiological activity, and is the base of ginseng's effect. After processing, the complicated changes are taken place in the constituents of ginseng, and some new substances produced. This paper aims to review the studies on chemical constituents and their mechanisms during ginseng processing, and the ideas, methods and the direction of the development of traditional Chinese medicine processing in the future.
