BACKGROUND: Seed cells with good proliferation and enough amounts are need in reconstructing artificial salivary gland in vitro. However, adult stem cells are difficult to be isolated from normal submandibular gland.OBJECTIVE: To in vitro isolate submandibular gland stem/progenitor cells for cloning culture using animal models of damaged gland tissue.DESIGN, TIME AND SETTING: Cytological in vitro experiment was performed at the Gu.izhou Provincial Key Laboratory of Cell Tissue Engineering, Zunyi Medical College from March 2006 to January 2007.MATERIALS: A total of 10 male Sprague Dawley rats aged 8 weeks were supplied by the Animal Center, Third Military Medical University of Chinese PLA.METHODS: The model of tissue damaged submandibular gland in 10 rats was made by deligation. One week later, the gland tissue was obtained to harvest submandibular gland stem/progenitor cells by enzyme digestion in vitro. Following 10-14 days of primary culture, small round cells were collected, purified and subcultured for monoclonal culture.MAIN OUTCOME MEASURES: Immunocytochemical staining and immunofluorescence staining results were measured in submandibular gland stem/progenitor cells. Growth curve was drawn to analyze the proliferation of submandibular gland stem/progenitor cells in vitro.RESULTS: Cells expressing laminin showed stem cell characteristics. Positive expression of CD29 suggested high-adherent and high-proliferative stem cell properties. Positive expression of keratin-19 indicated epithelium-derived submandibular gland stem/progenitor cells. Growth curve was near to "S" shape, and in vitro culture and proliferation was active.CONCLUSION: Submandibular gland stem/progenitor cells had the characteristics of tissue stem cells. They might be as a kind of seed cells for tissue engineered artificial salivary gland in further research.

OBJECTIVETo investigate the association between serum cardiac troponin I (cTnI) and cardiac function/structure in patients with chronic heart failure.

METHODSOne hundred and twenty patients with decompensated chronic heart failure were included. The patients were divided into cTnI normal group (cTnIn; n = 80) and cTnI elevated group (cTnIe; n = 40). Systolic dimension of the left atrium (LAd), the maximal width of the left ventricle (LVd), the thickness of the interventricular septum (IVS) and posterior wall (LVPW) during diastole, left ventricle ejection fraction (LVEF), E and A wave velocities ratio (E/A) were determined. Bivariate correlation analysis was applied to show the correlation of serum cTnI level with above indices. Partial correlation analysis was performed followed by multivariate logistic regression.

RESULTSLAd and LVd dimensions were significantly higher (P < 0.05), IVS, LVPW, LVEF and E/A ratio were significantly lower (P < 0.05) in cTnIe group than in cTnIn group. Moreover, serum cTnI was positively correlated with LAd, LVd, and inversely correlated with IVS, LVPW, LVEF and E/A ratio (P < 0.05). The correlation persistent after adjusting with sex, history of heart failure, NYHA functional class and treatment. In multivariate modeling, cTnI was positively associated with LAd, LVd and the history of heart failure, and negatively related with the treatment with angiotensin-converting enzyme inhibitor.

CONCLUSIONSerum cTnI correlated with cardiac structure and function. Intensively serum cTnI monitoring and suitable therapy strategy may be helpful to attenuate the cardiac remodeling in patients with chronic heart failure.

OBJECTIVETo explore metabolite profiling changes in serum of rats with pi-qi deficiency syndrome (PQDS) and pi-yang deficiency syndrome (PYDS) based on liquid chromatograph-mass spectrometer (LC-MS) technique, and to explore the essence of Pi-deficiency syndrome (PDS) from small molecule metabolite level.

METHODSTotally 21 male SD rats of SPF grade were randomly divided into three groups, the normal control group, the PQDS group, and the PYDS group, 7 in each group. Rats in the PQDS group overate for 1 day and fasted for 2 days. They drank freely and then swam to be exhausted in water at 35 degrees C - 37 degrees C for 15 successive days. The PYDS model was established by the same method for PQDS rats plus drenching 20% Folium sennae water extract (2 mL/100 g), once in the morning and once in the evening for one successive week. After modeling, models were evaluated according to rat general state, changes in body weight and rectal temperature. Serum metabonomic profiles were detected using LC-MS technique. Difference in inter-group metabolite spectrograms was analyzed using orthogonal partial least squares discriminant analysis (OPLS-DA). Potential biomarkers related to syndrome types in rat serum were selected via the parameter of variable importance in the projection (VIP).

RESULTSThe weight of rats in the PQDS group and the PYDS group decreased more significantly after modeling. The difference in prepost weight was statistically significant from that of the normal control group (P < 0.01). It was more obviously lowered in the PYDS group than in the PQDS group (P < 0.05). Compared with the normal control group, the rectal temperature of rats in the PYDS group and the PQDS group decreased (P < 0.05, P < 0.01). It decresed more in the PYDS group than in the PQDS group (P < 0.05, P < 0.01). Compared with the normal control group, levels of PC(19:0)/PE(22:0), PC(17:0)/PE(20:0), capric acid, oleic acid, stearic acid, succinic acid, fumaric acid, malic acid, glucose increased; arachidonic acid, linolenic acid, lauric acid, androsterone, 4-heptanone, dihydroxyacetonephosphate (DHAP) (6:0), and uridine decreased in the PYDS group and the PQDS group. Compared with the PQDS group, levels of PC(22:1), PC (22:6), PE (18:0)/PC (15:0), retinol, and deoxycytidine increased significantly in the PYDS group; PC (18:1), PC(19 :3), PC (20:3), PC (17:0)/PE (20:0), PC (19:1)/PE (22:1), PC (19:0)/PE (22:0), PC (17:1)/PE (20: 1), PC (16:1)/PE (19:1), cholic acid, hippuric acid, furoic acid, undecanedicarboxylic acid, palmitoleic acid, hydroxy stearic acid, eicosatrienoic acid, phenylalanine, tyrosine, glutamic acid, serine, carbamoyl aspartic acid, palmitoyl carnitine, tetradecanoyl carnitine, acetylcarnitine, and linoleylcarnitine decreased more significantly in the PYDS group.

CONCLUSIONSComparative contents of various serum metabolites changed significantly in PQDS and PYQS model groups. Some potential small molecular biomarkers related to PDS were preliminarily identified. These results might provide some data reference for exploring scientific connotation and pathological mechanisms of PDS.

OBJECTIVETo evaluate the effect of Xuezhikang (XZK) on cardiac function and serum C-reactive protein (CRP) in patients with chronic heart failure (CHF).

METHODSSixty-eight CHF patients were randomly assigned to two groups, the control group (30 cases) treated with angiotensin converting enzyme inhibitor, beta-receptor inhibitor, digoxin and diuretic, and the treated group (38 cases) with the above treatment plus XZK for six months. The changes of cardiac function and serum CRP level were measured by echocardiography and enzyme-linked immunosorbent assay (ELISA) respectively before and after treatment.

RESULTSCompared with those before treatment, the NYHA cardiac function grade, the left ventricular dimension end diastole (LVDd), and the left ventricular dimension end systole (LVDs) decreased significantly (P < 0.05), and the ejection fraction (EF) and E/A ratio increased significantly in both groups after treatment (P < 0.05) , however, the decrement or increment was more significant in the treated group than that in the control group respectively (P < 0.05); the serum CRP level decreased significantly in the treated group after treatment and showed a level obviously lower than that in the control group (P < 0.05), which changed insignificantly after treatment.

CONCLUSIONXuezhikang could improve cardiac function and decrease serum CRP level at the same time.
