1.Research progress in bone marrow-derived mesenchymal stem cells
Chinese Journal of Pathophysiology 2000;0(11):-
Bone marrow stroma provides the microenvironment for hematopoiesis and is also the source of mesenchymal stem cells. Marrow mesenchymal stem cells are capable of self-renewal and differentiation into all mesodermal cell types and neuro-ectodermal cells, such as osteoblast, chondrocyte, myoblast, T/L fibroblast, stromal cell, adipocytes, neuron, astrocytes, and so on. These abilities make the mesenchymal stem cells as an excellent target cell of tissue engineering, cell transplantation and gene therapy.

Objective:To explore the intervention effect of 321 health education guided by transtheoretical model on hemodialysis patients.Methods:A total of 107 cases of hemodialysis patients from January to December in 2019 in the Central Hospital of Panzhihua, Sichuan Province, were divided into a control group of 53 cases and a study group of 54 cases by table of random number. Patients in the control group received routine health education, and patients in the study group were intervened by 321 health education guided by transtheoretical model. The level of health literacy, symptoms, quality of life of patients in the two groups were evaluated by chronic disease patients health literacy scale, the Chinese version of Dialysis Frequency Severity and Symptom Burden Index (DFSSBI), and the Chinese version of Kidney Disease Questionnaire (KDQ) before and after the intervention.Results:After the intervention, the total score of the health literacy scale of patients with chronic diseases in the control group and the score of the three dimensions of information acquisition ability, communication and interaction ability, and willingness to be healthy were (89.16±11.04), (32.62±3.51), (31.48±3.61), (16.85±2.57), lower than those of the study group (99.86±11.46),(35.92±3.42),(35.73±3.92),(19.96±2.77), respectively, and the differences were statistically significant ( t values were -21.898--4.925, P<0.01). After the intervention, the total score, physical symptom score and psychological symptom score of the two dimensions of DFSSBI in the control group were (56.39 ± 8.21), (47.27 ± 6.85), (9.12 ± 1.31),higher than those of the control group (49.00 ± 6.31), (41.81 ± 5.35), (7.17 ± 0.95),respectively, and the differences were statistically significant ( t values were 5.226, 4.599, 8.827, P<0.01). After the intervention, the incidence of difficulty in falling asleep, fatigue, dry skin, itching, dry mouth in the study group were 38.89%(21/54), 38.89%(21/54), 27.78%(15/54), 27.78%(15/54), 25.93%(14/54), lower than those in the control group 66.04%(35/53), 62.26%(33/53), 49.06%(26/53), 49.06%(26/53), 45.28%(29/53), respectively, and the differences were statistically significant(χ 2 values were 5.124-9.224, P<0.05 or <0.01). The symptom scores of difficulty in falling asleep, fatigue, dry skin, itching, dry mouth in the control group were (7.44 ± 0.81), (7.34 ± 0.72), (7.42 ± 0.73), (8.62 ± 0.72), (7.82 ± 0.77), higher than those in the study group(6.11 ± 0.65), (6.02 ± 0.59), (6.15 ± 0.61), (7.12 ± 0.65), (5.84 ± 0.51) respectively, and the differences were statistically significant ( t values were 9.376-15.710, P<0.01). After the intervention, the total score of KDQ and the scores of physical symptoms, fatigue and depression in the control group were (106.46 ± 13.39), (23.87 ± 2.40), (22.71 ± 2.67), (22.52 ± 2.93), lower than those in the study group (116.89 ± 14.59), (27.12 ± 2.53), (25.16 ± 2.82), (27.12 ± 3.75), respectively, and the differences were statistically significant ( t values were -7.062--3.851, P<0.01). Conclusions:Intervention of 321 health education guided by transtheoretical model on hemodialysis patients can improve their health literacy and symptoms, reduce their symptom burden score and improve their quality of life.

Objective To investigate the protective effect and mechanisms of NF-?B decoy oli- godeoxynucleotides(ODNs)on rat liver graft following ischemia-reperfusion injury.Methods Ani- mals were randomly divided into 3 groups(n=8 in each group):control group,ischemia-reperfusion (IR)group,and decoy ODNs group,in which donor grafts were transfected with 120?g NF-?B decoy ODNs before graft procurement.Following 2 h of reperfusion,Kupffer cells(KCs)were isolated,and NF-?B biding activity was detected with electrophoretic mobility shift assay(EMSA),and TNF-?、IL- 6 mRNA expression was assayed by using RT-PCR method.Meanwhile,the liver and serum samples were collected,the histopathologic change of liver was examined by light microscope,and liver func- tion was analyzed.Results The NF-?B biding activity,TNF-?,IL-6 mRNA expression,and the ALT,TBIL levels in serum were significantly increased following 2 h of reperfusion in IR group as compared with those in control group(P<0.01).A large amount of degeneration and necrosis in hep- atocytes accompanied with obvious congestion in hepatic sinusoid occurred.However,these tested in- dexes were significantly ameliorated in decoy ODNs group as compared with those in IR group(P<0.01),and the architecture of hepatic lobules was remained.Conclusions KCs NF-?B activation fol- lowing reperfusion plays an important role in IRI in liver transplantation.Decoy strategy shows appar- ent effect on suppression of NF-?B activation,and thus inhibits the production of downstream cyto- kines,which protects the liver graft from IRI.

Objective To establish an HPLC fingerprint ofJinjing solid beverage,and provide experimental evidence of evaluating its quality.Methods Ten batches ofJinjing solid beverage were analyzed by HPLC under the gradient elution condition. A Kromasil C18 column(4.6 mm×250 mm, 5μm) was used, and the flow phase was acetonitrile-H2O(acidified to 0.1% with phosphoric acid) with gradient elution, and the detection wavelength was 327 nm, and the flow rate was 1.0 ml/min, and the column temperature was 35℃. The data were evaluated by the similarity evaluation software for TCM fingerprint.Results The HPLC fingerprint ofJinjing solid beverage were established. Twelve common peaks including chlorogenic acid were identified with similarity of more than 0.9.Conclusion HPLC method is a reliable, available and quick method, that provides a means for controlling and evaluating the quality ofJinjing solid beverage.
