One of the most problems is the diagnosis of the borderline lesion and/or borderline tumor to pathologists. It is necessary to make the correct diagnosis of the gastrointestinal borderline lesion and/or borderline tumor and correlative lesion such as gastrointestinal stromal tumors, gastrointestinal lymphoid proliferation and MALT lymphoma, IPSID, gastrointestinal adenoma and appendix carcinoid.[

Objective To observe the effect of atmospheric pollution on workers'α1-antitrypsin concentrationb in petrochemical enterprises.Methods During health examination,the workers were indivded into 3 groups according tO the length of job experience.Ⅰ group(<10 years)included 291 cases,aged 22-35 years old,Ⅱ group(10-20 years)included 634 cases,aged 33-45 years old,and Ⅲgroup(>20 years)included 427 cases,aged 44-55 years old.The normal control were individed int different group according to the status of petrochemical workers.,all the serum samples were detected on automatic biochemical analyzer,α1-antitrypsin levels were analyzed between the different groups.Results In group Ⅰ,the α1-AT concentration was 2.58±0.38 g/L(P>0.05)without significant difference compared with control.In group Ⅱ and Ⅲ,the concentration α1-AT were 2.02±0.43 g/L and 1.72±0.41 g/L respectively with significant differences compared with control.And the significant difference existed among the three groups of petrochemical workers..But the sigficant difference did not exist between different group of control people.Conclusion During the process of oil refining,the plants exhausted the polluted gas of nitrogen dioxide,olefins,alkanes,alcohols,carbonyl and other harmful substances,it influenced theα-AT levels of body.It is a good suggestion to decreas the petrochemical pollution,and to monitor the serum concentration of α-AT content among petrochemical workers,it might to reduce the incidence of lung disease of great significance.

As China witnesses constant development of its market economy and gradual deepening of reform in its medical and health cause,the ability of domestic hospitals to adjust their operational management strategies in due course is crucially related to their survival and development amidst market competition.Hospital managers,while stressing quality and economic control,should attach special importance to the brand effect of their hospital and step up hospital brand building,the focus of which lies in patient satisfaction and loyalty and hospital popularity and reputation.Only in this way can they constantly create advantages,enhance core competitiveness and put their hospital in an invincible position amidst market competition.

The Eleventh Five-year Program period will be a very important period in the historical development of China;it will also be a key period for domestic hospitals to deepen reform and achieve steady growth.Doing a good job of the five years' work will be of great significance to promoting reform of the medical and health system,strengthening and developing the hard-won good situation,speeding up hospital construction and growth,and solving such problems facing the common citizens as "it is difficult and expensive to see a doctor".The authors offer suggestions and hope to arouse discussions as to how hospitals ought to formulate a Eleventh Five-year Program that will meet their own growth needs with the guidance of a scientific approach to development.

Objective To investigate the safety,efficacy and effects of emergent percutaneous coronary intervention (PCI) in patients from Second Affiliated Hospital,Medical College,Zhejiang University with cardiogenic shock (CS) complicating acute myocardial infarction (AMI).Method Twenty-seven patients with CS complicating with AMI were treated by PCI with intraaortic balloon counterpulsation (IABP) support.The change of hemodynamics before and after IABP and PCI,the characteristics of PCI,the mortality during hospitalization, the major adverse cardiac events (MACE) and left ventricular ejection fraction at 30-day follow-up were observed.Results The hemodynamics were significantly improved after IABP.No patients died during PCI.Two patients died after PCI and the total mortality was 7.4% in hospital.During the period of 30-day follow-up, one patient died of heart failure.The left ventricular ejection fraction greatly improved at 30 days after PCI. Conclusions The data suggested that the use of IABP during PCI in patients with CS complicating AMI was safe, decreased mortality and improved prognosis.

Objective To discuss the diagnosis and inductive chemoradiotherapy of stage Ⅲ and stage Ⅳa invasive thymoma.Methods Clinical data of 13 cases with incomplete resected invasive thymoma were analyzed retrospectively,among which 8 cases were in stage Ⅲ and 5 cases in stage Ⅳa.All the 13 cases had invasion of major vessels,pericardial and lung tissues,or had metastasis of pleura and pericardium.Each patient got pathological diagnosis by fine needle aspiration,video-assisted thoracoscopic biopsy or anterior mediastinal biopsy.After 3 cycles of NP or CAP inductive chemotherapy and synchronous radiotherapy,tumors shrank and got palliative or complete surgical resection.The Follow up ranged from 2.8 to 9 years.Results All the 13 cases were malignant thymoma,including 4 cases of type B2,6 cases of type B3 and 5 cases of type C.7 patients got radical resection and 2 got palliative resection.9 patients survived more than 3 years after operation,7 patients survived more than 5 years,one patient even lived 8 years,and the other 4 patients without getting surgery died in 4 years.Conclusion Inductive chemoradiotherapy could shrink stage Ⅲ and stage Ⅳa invasive thymoma,reduce clinical stage,improve the resection rate,and prolong survival.

Objective The changes of cytokine expression on a genomic scale in CD4 + cell of mice c hronically infected with Schistosoma japonicum and their roles in the pathog enesis of schistosomiasis were studied. Methods CD4 + cells were isolated from sp le ens of mice 13 wk infected with Schistosoma japonicum. We used the cDNA micr oarr ay technique to explore the cytokine gene expression profile of CD4 + cells f ro m normal and chronic infected mice. Three-color flow cytometry was performed to study intracellular protein levels of IFN-?、IL-4 of CD4 + cell. Results In the CD4 + cell of chronically infected mice, IL-4 was remarkably increase d at both transcription and protein expression levels (P

Objective To study the image features and clinical significance of 3-dimensional (3-D)and multiplanar reconstruction with spiral CT(SCT) in cervical spinal fractures.MethodPlain film radiography and spiral CT scanning were taken for 26 cases of cervical spinal fractures.The type of fractures, diagnositic successful rate, parameter of scanning and late stage managing methods were investigated retrospectively to find out the effective difference between the diagnosis of plain X-ray and SCT. The imagin location of fractures,sequence of cenrum, heighth of centrum, fracture line, auxillary structure and rotation/dislocation of the fractures were emphasized to evaluate the advantages of 3-D imaging.ResultIn the 26 cases, there were 4 Jefferson fractures, (in which 1 combined with articular dislocations), 17 C2 spinous process fractures, (in which 1 had failure of plain X-ray diagnostic), 1 Hangman fracture, 2 C1～2 imbalance, (in which 1 had failure of plain X-ray diagnostic).There were 2 cases of axoid longitudinal fractures without obvious dislocation. The diagnositic successful rate were 100% in SCT group, while 65% in X-ray group in which 6 cases had diagnostic failure and 3 cases had fracture mis-diagnozing as dislocation.The anatomical structure of upper cervical spine was complicated and was significantly different from other cervical spine constructions. Spiral CT could reveal high resolution images of the upper cervical spine, morphosis of vertibral canal, dislocation information of fracture mass and its relation with neighbouring tissues. Especially in C1 burst fracture,C2 dens fracture and C1～2 dislocation, SCT could provide clear 3-D information of the size of collateral mass and the dislocation degree, furthermore, images could be rotated freely to observe the fracture in any proper section. That provides important information for the decision of operation, selection of operation types and evaluation of operation dager.ConclusionThe spiral CT scan and 3D reconstruction can reveal fracture better.The advantages of SCT are suggested that this diagnostic modality may be the standard method for the initial evaluation of the upper cervical spine injury.
