The present new situation is calling for our advancement with the time and the development of the hospital in the spirit of the time at an unprecedented rate. To achieve this goal,the author brings forward"three musts" as follows:the spirit of the time must be entertained in following the trend of development;scientific method of adhering to self-reliance by drawing on others'strong points must be upheld;the prinlciple of making breakthroughs by proceeding from the actual situation must be maintained.

Objective:To explore and analyze detection rate of lung lesions of 16 slice spiral CT low dose of TLC technique and conventional radiography. Methods: Selected 120 lung disease patients in our hospital , they were randomly divided into 16 layers of low dose spiral CT examination examination group and conventional thin chest lung examination group, each group had 60 patients,compared two groups’ detection rate of contrast. Results:16 thin layer of low-dose spiral CT technology inspection found 8 pulmonary fibrosis patients, including 6 emphysema patients, 5 tuberculosis patients, 2 lung cancer;there were 21(35%.00) lung disease in total.While conventional chest X-ray examination revealed 2 pulmonary fibrosis, 1 man tuberculosis, 2 lung cancer.There were 5(8.33%) lung disease in total. The detection rates of 16 slice spiral CT low dose of TLC examination of lung and conventional radiography examination of lung lesion had differences (x2=12.5696, P<0.05). Conclusion:16 slice spiral CT low dose of TLC inspection has higher detection rate compared with the conventional chest X-ray examination on lung lesions ,it can exam lung disease effectively, its radiation damage on physical examination and medical staff is small, and can be widely applied, it is worth to popularize.

The present paper explores how to build a stronger contingent of scientific and technical cadres in the new situation by acting on the important thought of "Three Represents".The accomplishment of this aim requires straightening out "three outlooks"(world outlook,life outlook and value outlook),professional ethics and matter of fact attitude,and putting one's talent in a right relationship to the hospital's cultivation.

In the new situation,party leaders and cadres should take the lead in culturing communist accomplishment,and must reinforce theory study,strengthen communist belief,culture moral quality,culture noble trait,create a positive image.

BACKGROUND: A great deal of free radicals can be induced,which results in peroxidation of the whole body. The antioxidant activity and the abilities of scavenging free radicals of proanthocyanidins(GSP) have been well documented,but related researches about the protective role in radiation damage were less reported.OBJECTIVE: To investigate the protective role of GSP combined with casein in 60Co-y radiation-induced peroxidative damage.DESIGN: Observing and comparative study based on animal model.SETTING: Nutrition Department of Daping Hospital Affiliated to the Third Military Medical College of Chinese PLA.MATERIALS: This study was carried out in the Third Institution of Field Operation Surgery, the Third Military Medical College of Chinese PLA.Eighty healthy Wistar rats,clearage,were adopted,ith weight from 180 to 220 g,half male and half female were adopted.METHODS: Rats were divided into four groups: normal control group,irradiation group,GSP group and GSP + casine group with 20 rats each. Rats in GSP group were fed routinely and supplemented with 1% GSP for 10days,which was replaced by 1% GSP and 5% casein. All rats except those of control group were exposed to whole-body 60Co-g amma-radiation at a dose of 7 Gy. Seven days later,6 survival rats randomly selected from each group were killed.MAIN OUTCOME MEASURES: The level of serum malondialdehyde (MDA), activities of serum superoxide dismutase(SOD),spleen index and the number of peripheral white blood cell(WBC).RESULTS: Serum MDA was obviously increased,accompanied by obviously attenuated SOD activity after irradiation; the level of MDA in both GSP group and combined group was found lower than that in irradiation group with statistical significance between them(P<0.01), the activity of SOD was significantly higher than that of irradiation group(P<0.01 ) . Markedly atrophic pathological change in spleen could be observed in irradiated rats,and meanwhile spleen index declined with the number of WBC notably decreased. But spleen index in both GSP group and combining group was markedly higher than irradiation group(P<0.05),and the same comparing result could also be found in the number of WBC(P<0.01 ).CONCLUSION: Peroxidative impairments could be obviously attenuated,and decrement of WBC could also be improved by single GSP or alternatively GSP combined with casein,with the latter showing greater effects in respect of improving immune function following irradiation,cellular chemical imbalance,and consequently the life quality.

The present thesis analyzes and discusses the concept of medical service strategy and its relation to medical equipment researches theoretically According to the prediction of future war,the author puts forward the idea and method of present strategy as well as developing strategy for medical equipment researches.And it also showes the critical points of them.

0.05).Conclusion:HLA-DQA1*0102 and DQA1*0104 were associated with protection from chronic HBV infection and development of LC,respectively.There was no significant association between HLA-DQA1 and development of HCC in chronic HBV infection patients.

Objective To investigate the role of vascular endothelial growth factor D(VEGF-D) and vascular endothelial growth factor receptor 3(VEGFR-3) in lymphangiogenesis and lymphatic metastasis of colon carcinoma by observing the expression of VEGF-D and VEGFR-3,and calculated lymphatic vessel density(LMVD) in colon carcinoma. Methods The expressions of VEGF-D and VEGFR-3 were observed by SP immunohistochemistry in 55 colon carcinoma samples of different stages and differentiation degrees.LMVD in colon carcinoma was calculated by using Podoplanin as the specific marker of lymphatic endothelium. Results The positive expression of VEGF-D in colon carcinoma(54.5%) was higher than that in peritumoral tissues(P

Objective: To investigate the effects of grape seed proanthocyanidin(GSP) and casein peptide on the liver function and protein nutritional status in rays irradiated rats. Methods: Adult wistar rats were randomized into four groups with 20 rats in each group including normal control, radiation control, GSP and GSP+casein peptide combined groups. The GSP group was fed with basic diet containing 1% GSP, the combined group was fed with basic diet containing 1% GSP plus 5% casein peptide. Animals except normal control were irradiated by 60 Co? rays(7Gy) 10 days later. 6 survivors were randomly selected from each group and killed on the 7 th d after radiation. The levels of the total protein (TP) and the albumin (ALB), the activities of the glutamate pyruvate transaminase(GPT) and the glutamate oxaloacetale transaminase(GOT) in serum were measured. The change of the body weight of the animals was observed during the experiment time. Results: After radiation the body weight of the rats dropped sharply. The loss of the weight in combined group were significantly lower than in radiation control group and in GSP group(P

Objective: To study the protective effects of L-Carnitine(LC) against the kidney damage induced by cisplatin(DDP).Methods: 36 Female adult Wistar rats were randomly divided into Control group,DDP group and LC+DDP group.Control group and DDP group were fed a basic diet,while LC+DDP group were added 1%LC.After 7 days,DDP group and LC+DDP group received cisplatin i.p.(5 mg/kg body weight),while Control group received normal saline i.p.After 4 days,rats were killed,the change of serum Cr and BUN,and tissue MDA and GSH in kidney were measured and the kidney structure was also observed.Results: Compared with DDP group,the contents of serum Cr、BUN and kidney tissue MDA of LC+DDP group declined very significantly,while the contents of kidney tissue GSH increased significantly.The pathological slice indicated that the renal structure of LC+DDP group was significantly improved.Conclusion: Dietary supplementation with LC might protect kidney against the damage induced by cisplatin in some extent,which might be partially correlative with the antioxidative effects of LC.
