Laparoscopic curative gastrectomy has been widely adopted because it is minimal invasiveness.The efficacy of laparoscopic gastrectomy is comparable to that of open gastrectomy for patients with early or advanced gastric cancer,but few studies of laparoscopic total gastrectomy combined with distal pancreatectomy and splenectomy for patients with advanced gastric cancer have been reported.Seven patients with advanced gastric cancer received laparoscopic total gastrectomy combined with distal pancreatectomy and splenectomy at the First Hospital of Jilin University from September 2010 to September 2011.The mean operation time,blood loss,postoperative hospital stay and the nunber of lymph nodes resected were (218 ± 24) minutes,(366 ± 174) ml,( 14.6 ± 2.8 ) days and 32 ± 15,respectively.Two patients were complicated by pancreatic juice leakage and were cured with drainage. No anastomotic leakage,abdominal bleeding or mortality was observed. With the development of techniques and equipments,laparoscopic total gastrectony combined with distal pancreatectomy and splenectomy is safe and feasible in selected patients.

OBJECTIVETo study Astragalus membranaceus absorption characteristic of nitrogen, phosphorus and potassium at different growth stages.

METHODThrough the field experiment and the sampling analysis, the absorbing capacity of nitrogen, phosphorus and potassium as well as the growth of plant at different growth stages in A. membranaceus were analyzed.

RESULTThe dry matter accumulation reached 88.22% of the total accumulation in 100-163 days after seedling emergence, The content of N, P, K in the stem was higher than that in the root system. Nitrogen, phosphorus and potassium absorbing capacity in the stem, the leaf and the root systems was N > K > P. In the whole growth period, nitrogen accumulation reached the highest, and followed with the accumulation of potassium, and the accumulation of phosphorus was the lowest. In the last phase of the exuberant growth period, the accumulation intensity of nitrogen, phosphorus and potassium reduced. During the harvesting time, the accumulation intensity of nitrogen and potassium increased, and the accumulation intensity of phosphorus remained stable.

CONCLUSIONThe dry matter accumulation reached the maximum in 100-163 days after seedling emergence. The absorption strength of nitrogen, phosphorus and potassium in aerial part reached the maximum in 100-132 days after seeding emergence, the maximum absorption comes earlier than that of phosphorus and potassium, at that time the needs of nutrients reach the highest. For producing of 100 kg A. membranaceus 2.32 kg N, 0.323 kg P2O5, 1.62 kg K2O are needed to be absorbed from soil and fertilizer.

The fibrous roots are the residues of production of cut crude drug of Danshen (Salvia miltiorrhiza). Enzymatic pretreatment and ultrasonic extraction are beneficial to extract effective constituents from fibrous roots more effectively. The present research was to optimize the enzymatic parameters by the central composite design and response surface method. Under the best conditions, the yields of total tanshinones and total salvianolic acids in the extracts of enzymatic pretreatment increased by 113.92% and 30.64%, comparing with the non-enzymatic extraction, respectively. TLC analysis also showed that the types of effective constituents in the two samples were not affected by enzymatic hydrolysis. Meanwhile, the complex correlation coefficients of the mathematical models were high, which provided a good prediction.

ObjectiveTo synthesize 99Tcm labeled hydrazine-nicotinamide ( HYNIC)-c (RGDfK)and evaluate its biodistribution and imaging in the severe combined immunodeficiency (SCID) nude mice bearing human lung adenocarcinoma.Methods( 1 )Tcm-HYNIC-c(RGDfK) was prepared by a two-step method using tricine and ethylenediamine diacetate (EDDA) as coligands and HYNIC as the dual functional chelator.The bioactivity of 99Tc m-HYNIC-c (RGDfK) was measured by cell binding experiments.(2) The nude mice bearing human A549 lung adenocarcinoma were randomly divided into 7 groups with 5 in each group.The 7 th group was the competitive inhibition control group and was administrated 100 μg HYNIC -c (RDGfK) 30 min earlier before the injection of 99Tcm-H Y N IC-c ( RGDfK ).The nude mice were scanned at 0.5,1,2,4,8 and 12 h respectively after intravenous injection of 7.4 MBq 99Tcm-HYNIC-c(RGDfK).The biodistribution of the agent was measured as ％ ID/g.The uptake ratio of tumor to muscle (T/NT) was also measured by placing ROI on 99Tcm-HYNIC-c(RGDfK) SPECT imaging.(3)Gamma imaging was performed in 6 mice including 3 in the competitive inhibition control group at 0.5,1,2,4,8 and 12 h post injection.ResultsThe labeling yield of 99Tcm-HYNIC-c(RGDfK) was more than 90％,and the radiochemical purity was more than 95％.99Tcm-HYNIC-c(RGDfK) can specifically bind with A549 adenocarcinoma cells with a binding rate up to 36.14％.Biodistribution study showed that the uptake in the kidney was above 20 ％ ID/g during 0.5 - 8 h post injection.The ％ ID/g in tumor was 10.52 ± 1.48 at 0.5 h,17.26 ±2.81 at 8 h,and 8.93 ±0.90 at 12 h.However,the ％ ID/g in tumor was only 2.29 ±0.85 in the competitive inhibition control group at 0.5 h.The highest T/NT was 6.87 at 8 h by the ROI analysis.Xenograffted tumors could be visualized at 1 h and delineated more clearly from 4 to 8 h post injection of 99Tcm-HYNIC-c(RGDfK).Conclusions99 Tcm-HYNIC-c (RGDfK) can be readily synthesized.Its binding with A549 lung adenocarcinoma cells is specific and the binding rate is high.

OBJECTIVETo evaluate the efficacy and adverse reaction of total glucosides of paeony (TGP) combined with sulfasalazine (SSZ) in the treatment of ankylosing spondylitis (AS).

METHODSSixty-seven AS patients were randomly assigned to 2 groups: the treatment group (34 cases) treated with TGP and SSZ, the control group (33 cases) with methotrexate (MTX) and SSZ. Changes of clinical efficacy related indexes including lumber pain index, morning stiffness time, peripheral joint pain index, thoracic expansion, Schober test, Bath AS disease active index (BASDAI), Bath AS functional index (BASFI), the levels of erythrocyte sedimentation (ESR) and C-reactive protein (CRP), and X-ray of sacroiliac joint were observed.

RESULTSThe clinical efficacy indexes were significantly improved after treatment in the two groups (P < 0.05). Except that the improvement of lumber pain index and peripheral joint pain index was better in the treatment group than that in the control group (P < 0.05), no significant difference was found in the other indexes between the two groups. The occurrence of adverse reation was less in the treatment group than in the control group (P < 0.05).

CONCLUSIONTGP treatment combined with SSZ shows favorable effect on AS with less and milder adverse reaction.

OBJECTIVETo confirm the amount of fertilizer and the ration of fertilizer.

METHODThrough the experiment of planting Salvia miltiorrhiza in pot and in field were carried out.

RESULTWhen N:P = 1:1, The production was 1.8 times more than the contrast group in plotting experiment, and in field the production of the highest fertilizer plot were 2.5 times more than the contrast and the higher and high fertilizer plot is 2.25 and 1.2 times respective were than those in the contrast group.

CONCLUSIONThe proper ration of nitrogenous fertilizer and phosphorous fertilizer is 1:1. Nitrogen shows negative effects to the accumulation of tanshinon IIA, the more the nitrogen ous fertilizer, The less the content of tanshinon IIA. In contrast, phosphor ous fertilizer shows good effects on the accumulation of tanshinon IIA. Phosphorous fertilizer could alleviate the decline of the content of tanshinon IIA by using nitrogenous fertilizer. The accumulation peak of the tanshinon IIA emerge in the period of 150 d.
