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.

Five genes that are closely related with leukemia were detected and identified using COREMINE Medi-cal, and the abstracts of related papers covered in PubMed were analyzed with the biomedical text mining tool, Chilibot, which showed that leukemia interacts with the 5 genes detected using COREMINE Medical.

Objective To evaluate the clinical application of the tissue Doppler imaging (TDI) in investigating the cardiac longitudinal systolic function in the patients with type 2 diabetes mellitus. Methods Forty-two patients with type 2 diabetes mellitus and 25 volunteers underwent TDI. The long axis myocardial peak systolic velocity (Sm), displacement (Dm) and strain rates (SRs) of 18 segments in different left ventricular walls were measured.Results The Dm and SRs of left ventricular wall in diabetic group dramatically decreased (P<0.01). Meanwhile, the diabetic combined hypertension group had much lower Sm of ventricular middle segments than the control group (P<0.05).Conclusion The stain rate and tissue tracking are sensitive and reliable to evaluate the early local cardiac systolic function in the patients with diabetes mellitus. TDI can be used as an noninvasive method to detect early systolic dysfunction.

BACKGROUND:The use of bio-membrane guided bone regeneration in maxilary sinus augmentation is a research hotspot in implantology at present. OBJECTIVE:To investigate the osteogenic effect of guided bone regeneration in maxilary sinus augmentation using colagen membranes. METHODS:The first maxilary molars of nine adult female beagle dogs were extracted and ful-thickness flap was reflected bilateraly, then the sinus floors were lifted with simultaneous implantation. Bio-Oss was placed into the new space under the sinus membrane. On the experimental side in each dog, the bio-membrane covered the osteotomy window. On the control side, the flap was sutured directly, and was not covered by bio-membrane. Two animals were sacrificed at 4, 12, and 24 weeks after surgery, respectively. Gross observation, biomechanical testing and histological examinations were performed. RESULTS AND CONCLUSION: In gross view, new bone formation was observed in al maxilary sinuses. The pul-out force increased with time. At week 24, a significant difference in the pul-out force was noted between the two groups (P < 0.05). Histomorphbomatrical analysis showed much more new caluses at the experimental group than the control group at weeks 12 and 24 after surgery (P < 0.05). The bio-membrane guided bone regeneration has a better effect on new bone formation in the sinus augmentation.
