Objective:To study the relationship between hyperviscosity syndrome(HVS) and platelet membrane glycoproteins(GP) sub group changes.Methods: CD62P,CD63,CD31 and CD41 were measured by flow cytometry(FCM). The hemorrheoloic parameters of HVS patients were compared with those of normal aged group and normal young group.Results:(1)The CD62P,CD63 and CD31 of aged and young HVS patients before therapy were obviously higher than those of the normal aged group and normal young group.(2)Combined measurement could improve the detecting positive rate of HVS patients up to 92% 100%, with the sensitivity being 95.3%.(3)Bamyl decreased CD62P,CD63 and CD31,which was obviously correlated with ?b and ?p. Conclusion:The alteration of platelet membrane GP positive expression may be a parameter for early diagnosis and clinical outcome observation.

· AIM: To study the clinical characteristics of metastatic bacterial endophthalmitis.endophthalmitis were retrospectively studied.manifestation was found in 17 cases (77%), iridal purulent nodules in 2 cases and retinal purulent embolism In 3 cases. The total number of leucocytes and neutrophilic granulocytes was elevated markedly, while lymphocyte count was reduced significantly in early stage. Positive rate of bacterial cultivation was 36%.dophthalmitis often have apparent extraocular infected situation before eye Is involved. Ocular appearance and laboratory examination have some specificity in early stage, while bacterial cultivation, as a golden standard,needs to be further improved.

The clinical prescriptions of hemoptysis that built by Menghe physician Ma Peizhi were collected, and were analyzed by the method of unsupervised data mining, such as association rules and clustering algorithm. From the prescriptions, we got the frequency of drugs, the association rules among drugs, 10 core drug combinations and 5 new prescriptions. Accordingly, after the analysis, Menghe physician Ma Peizhi had rich experience in the treatment of hemoptysis. His therapy for hemoptysis was clearing heat and moistening lung, dispel heat from blood to stop bleeding, and enriching yin and blood. And we can also make a conclusion that the TCM inheritance support system is of great practical value for minning the old doctors' clinical experiences.

Analyzed the prescriptions for phlegm retention syndrome that built by Ma Peizhi by the association rules and clustering algorithm, the frequency of drug usage and the relationship between drugs could be get. And from that we could conclude the experiences for phlegm retention syndrome of Ma Peizhi of menghe medical genre. The results of the analysis were that 18 core combinations were dig out, such as Citri Exocarpium Rubrum-Eriobotryae Folium-Citri Reticulatae Pericarpium. And there were 9 new prescriptions were found out such as Aurantii Fructus-Citri Exocarpium Rubium-Eriobotryae Folium-Citri Reticulatae Pericarpium. The results of the analysis were proved that Ma Peizhi of Menghe Medical Genre was good at curing phlegm retention syndrome by using the traditional Chinese medicine of mild and light, such as the medicines of mild tonification, and clearing damp and promoting diuresis.

Objective To analyze the result of treatment for acute-on-chronic liver failure patients with fast high efficiency Nucleoside and to explore the relations among inhibition to virus replication , liver failure development and immune rejection .Methods Sixty-two cases of acute-on-chronic liver failure pa-tients with HBV DNA(+) were divided into study group (treated with a kind of fast and nucleoside , n =30) and control group( n =32).HBV DNA,CD4 +T,CD8 +T, C3,C4 TBIL,PTA were observed at treat-ment 0w,2w and 4w.Results All of the study and control group patients , serum HBV DNA were positive before treated.And the levels of CD4+,CD8 +,C3,C 4,TBIL,PTA of study group were not significantly compared with control group .At treatment 2w , the rate of HBV DNA diverted negative in study group 90.0%(27/30), was significantly more then control group (9.4%, 3/32)(χ2=37.14 , P <0.01).But the CD4 +,CD8 +,C3,C4,TBIL,PTA levels were not significantly however between study and control group . At treatment 4w ,the rate of HBV DNA diverted negative in study group (96.7%, 29/30), was significant-ly more then control group(12.5%,4/32) (χ2 =40.74, P <0.01).CD4 +, CD8 +,C3,C4,TBIL,PTA levels of the study group were significantly more compared with the control group .The CD4 +level of study group (495.33 ±89.91)cells/ml, was higher significantly then control group (270.34 ±97.74)cells/ml( t=9.42, P <0.01),the CD8 +level (571.03 ±120.15 ) cells/ml, was higher significantly then control group(224.88 ±79.68)cells/ml( t =13.45, P <0.01).The C3 level of the study group (0.28 ±0.11) g/L, was lower significantly then control group ( 0.68 ±0.13 ) g/L ( t =13.13 , P <0.01 ) , the C4 level (0.12 ±0.06)g/L, was lower significantly then control group (0.23 ±0.10)g/L( t =4.92, P <0.01). The TBIL level of study group ( 653.93 ±131.02 )μmol/L, was higher significantly then control group (285.63 ±154.63)μmol/L( t =10.09, P <0.01),the PTA level (17.13 ±7.07)%, was lower signifi-cantly then control group(50.94 ±13.68)%( t =12.10, P <0.01).The death rate of the study group( 57.9%) was higher significantly compared with the control group (28.1%)(χ2 =6.39, P <0.05).Con-clusion Treatment of chronic severe hepatitis with fast and high efficiency nucleoside may arise the T cell subset level and make the immune rejection strength , as a result the liver failure maybe far away from cure .

BACKGROUND:The traditional two-dimensional culture system has been widely used in the in vitro culture of human tissue stem cells,but it cannot really simulate the three-dimensional physiological microenvironment in the body, which is not conducive to the study of the biological behavior of human stem cells. OBJECTIVE: To detect the effect of the bioactivity of Col-Tgel in human hematopoietic stem cells (HSCs) and mesenchymal stem cells (MSCs)in vitro and in vivo,by constructing a three-dimensional culture system stimulating the physiological microenvironment of the body. METHODS:(1)In vitro co-culture:Green fluorescent protein labeled MSCs(MSCs-GFP)and human umbilical cord blood CD34+cells were co-cultured in Col-Tgel for 3 days (three-dimensional culture group). Human umbilical cord blood CD34+cells were cultured in Col-Tgel for 3 days as single culture group. MSCs-GFP and human umbilical cord blood CD34+cells were co-cultured in Transwell chamber for 3 days as two-dimensional culture group. Human umbilical cord blood CD34+cells were cultured routinely as control group. The percentage of CD34+CD38-CD45RA-CD90+cells in each group was measured by flow cytometry. In situ immunofluorescence staining was used to detect the activity of cells that were co-cultured in Col-Tgel.(2)In vivo transplantation:NOD/SCID mice subjected to 24-hour X-ray irradiation were divided into two groups: in experimental group, MSC-GFP cells were resuspended in Col-Tgel and transplanted into the tibia of NOD/SCID mice; in control group, MSCs-GFP were resuspended in PBS and transplanted into the tibia of NOD/SCID mice. The MSC-GFP growth in the bone marrow was detected by two-photon/confocal microscopy at 3 days post transplantation. RESULTS AND CONCLUSION: (1) After co-culture in Col-Tgel for 3 days, the percentage of CD34+CD38-CD45RA-CD90+cells in the three-dimensional culture group was 2.8 times that of the two-dimensional culture group, indicating that the MSCs significantly promoted the expansion of CD34+CD38-CD45RA-CD90+cells in the Col-Tgel. The percentage of CD34+CD38-CD45RA-CD90+cells in the three-dimensional culture group was increased by 4.5 times compared with the single culture group and increased by 1.5 times compared with the control group. Immunofluorescence staining showed that the cell viability of human MSCs and human umbilical cord blood CD34+cells was not affected after co-cultured in Col-Tgel for 3 days.In the in vivo transplantation experiment,MSC-GFP cells could survive in the medullary cavity.In summary, Col-Tgel provides a new strategy for stem cell culture and in vivo growth by forming a three-dimensional system similar to the physiological environment in vivo.
