Objective To find out about the allocation of large size medical facilities in Tangshan City so as to make rational use of its health resources. Methods On the spot investigations were combined with surveys through questionnaires to find out about the allocation of large size facilities in second tier hospitals and above in the city. Results There are altogether 109 large size medical facilities in the city, averaging 15.60 per million people. The allocation number is pretty high, and yet the distribution is quite irrational, with the city proper owning 70.67% of the facilities while its population and land area account for only 24.06% and 8.10%. Conclusion The allocation number has been increasing rapidly and the level of grade is rather high, and yet there lacks equity in distribution.

AIM: To investigate the effect of endothelin (ET), angiotensin II (AngII) and homocysteine (Hcy) on C-type natriuretic peptide (CNP) synthesis and release. METHODS: Human endothelial cell was cultured; CNP was measured by radioimmunoassay method. RESULTS: ET and AngII could augment CNP synthesis in human endothelial cells. Compared with control group, 10-9,10-8,10-7 mol/L ET and Ang II increased CNP content of endothelial cells by 1%(P>0.05), 49%(P<0.05),117%(P<0.01) and 137% (P<0.01),165%(P<0.01),201%(P<0.01),respectively. A great dose of ET and Ang II also stimulated CNP release from cultured human endothelial cells. Hcy had no effect on CNP synthesis, but 10-9,10-8,10-7 mol/L Hcy enhanced CNP release from cultured human endothelial cells by 17%(P>0.05),84%(P<0.01) and 555%(P<0.01), respectively. CONCLUSION: ET, AngII and Hcy might be involved in the synthesis and release of human endothelial cell CNP.

In previous studies, we demonstrated 10 types of lymphocytes in lymph nodes, each exhibited a different fluorescent color by our thioflavine staining method. Among them, 4 types were able to differentiate into plasma cells of the same fluorescent colors. In the present study, different types of lymphocytes were demonstrated in human peripheral blood by their different fluorescent colors after thioflavine staining. The lymphocytes from the venous blood of 50 healthy persons were isolated with Ficoll-Conray solution and E-rosette and EAC-rosette tests and fluorescent staining with thioflavine were performed. Most of the lymphocytes in peripheral blood are small ones with nuclei and cytoplasm showing blue fluorescence and the blue fluorescence of the cytoplasm is paler than that of the nuclei. The nuclei in a part of these lymphocytes have distinct boundaries. The nuclei in another part of these lymphocytes are smaller and with indistinct boundaries and indentation on one side and show dim fluorescence. Other lymphocytes show different fluorescence. Some show blue round nuclei with distinct nuclear membrane, and no color of fluorescence in cytoplasm, but with blue white patches on one side of the nuclei. Some show dark blue nuclei and bright blue cytoplasm and others show orange yellow or orange red nuclei and yellow cytoplasm. In addition, lymphocytes of grayish blue or grayish yellow nuclei and bluish green cytoplasm or lymphocytes of yellowish fluorescence may be seen at times. Very few lymphoeytes of orange red nuclei with nearly no cytoplasm may be seen occasionally.The lymphocytes with blue fluorescence and indentation on one side of nucleus, those with blue nuclei and blue white patches in the cytoplasm as well as those with orange yellow nuclei and yellow cytoplasm can form E-rosettes with sheep erythrocytes. They are T cells. The lymphocytes with distinct boundaries of nucleus, small size and blue fluorescence those with dark blue nuclei and bright blue cytoplasm as well as those with orange red nuclei and yellow cytoplasm can form EAC-rosettes with sheep erythrocytes sensitized by specific antibody and complement. They are B cells. The lymphocytes with blue nuclei and blue white patches may transform into lymphocytes with orange yellow nuclei and yellow cytoplasm under ultra-violet light irradiation. The latter are few in number in the blood but may be progressively increased in number on prolonged observation. They belong to Group Ⅲ of lymphocytes and are mainly located in the paracortical thymus-dependent zone of lymph nodes. The sma ller lymphocytes with blue fluorescence and distinct nuclear boundary may transform into lymphocytes with orange red nuclei and yellow cytoplasm, which are also very few in number in the blood and are also progressively increased in number on prolonged observation. They belong to Group Ⅱ of lymphocytes and constitute the main component of lymph nodules in lymph nodes.
