Proteins extracted from two varieties of Chinese roses leaves were separated by two- dimensional polyacrylamide gel electrophoresis (2-DE) with immobilized pH gradient (IPG). Many difference proteins were isolated with molecular weights ranging 10-30 kDa and pI5-6. Three proteins of high levels observed in a gel were excised and identified using peptide mass fingerprinting and MS-MS. A summary of the identified proteins and their putative functions are presented. They are identified as eIF-5A、LEA protein and Hsp17. 5. Functions of these proteins in plant tolerance to high temperature were discussed.

BACKGROUND:The intestine is not only the main target attacked by sepsis but also the vital organ which mediated sepsis. The recovery of the damaged intestinal barrier structure and function is related to the occurrence and outcome of multiple organ dysfunction syndrome (MODS). How to protect and reduce the damage of the intestinal mucosa and how to promote the reconstruction of the intestinal mucosa have been the important topics in sepsis for many years. This study aimed to investigate the influential factors of intestinal mucosal reconstruction after intestinal epithelial injuryin vivo in a mouse model of sepsis.METHODS:Mice were subjected to cecal ligation and puncture (CLP) for induction of sepsis to assess intestinal mucosal damage, epithelial cell apoptosis, and transformed number of goblet cells, and to detect the concentration of TNF-α, IL-1 and TGF-β1 and TFF3 (trefoil factor 3) expression in the small intestinal mucosa. All above were performed by HE staining, western blot, ELISA and immunohistochemistry respectively. The experimental animals were divided into a sepsis group and a sham-operation group. The animals with sepsis were separately killed at 6 (7 animals), 24 (7 animals) and 48 hours (7 animals) after CLP.RESULTS:Injured intestinal mucosa was observed in the 3 groups under a light microscope, in which damage scores in the 24-hour and 48-hour groups were higher than in the 6-hour group and no difference was found between the two groups. Moreover, less of goblet cells or other epithelial cells adjacent to the injured surface migrated into the wound to cover the denuded area. The number of goblet cells was substantially decreased in the three CLP groups compared with the sham-operation group. Protein levels of IL-1 and TNF-α were significantly increased by 3-4 fold at all time points when compared with the sham-operation group, and cleaved caspase-3 by 4 fold. Although TFF3 expression was modestly increased for 6 hours after the onset of CLP, it appeared to decline at 24 hours and 48 hours as shown by Western blot. A similar tendency was observed upon TGF-β1, i.e. the protein level was not elevated at 24 hours and 48 hours, but increased modestly at 6 hours.CONCLUSIONS:Sepsis from CLP shows less restitution on the surface of injured intestinal mucosa. There is evidence that both constant inflammatory reaction and epithelial cell apoptosis may affect mucosal reestablishment of the intestine at the onset of sepsis. Mucosa after severe sepsis showed the state of high inflammation, and declined goblet cell function and mucosal reconstruction, which affected the repair of damaged intestinal barrier. Constant inflammatory reaction, and declined goblet cell function and mucosal reconstruction ability may affect the reestablishment of intestinal mucosa at the onset of sepsis.

OBJECTIVETo investigate the published randomized controlled trials (RCTs) concerning the treatment of liver carcinoma with TCM, and to assess their methodologic quality and quality of report.

METHODSRelated RCT reports published from Jan. 2004 to June 2006 were retrieved by computerized and manual search, and the criteria of CONSORT statement (revised edition) were applied to assess the articles searched.

RESULTSForty-six articles up to the RCTs inclusion standard were searched, among them, the method for randomized distribution sequence producing was described in 9 articles (19.57%), none mentioned randomization concealment and the estimation of the sample size. The blinded method was adopted in 3 articles (6.52%), the inclusion and exclusion criteria were reported in 18 (39.13%) and 1 (2.17%), respectively. Participant flow was reported in 3 (6.52%), but flow chart was not described in any article. Patients' compliance was reported in 5 (10.87%), and the concrete P value was reported in 6 (13.04%), but with no report involving the confidence interval. Adverse events were described in 15 (32.61%). Only 5 articles (10.87%) discussed the limitations of the present study in their section of discussion.

CONCLUSIONThe quality of RCTs reports on treatment of liver carcinoma with TCM are still in low quality, not meeting the CONSORT statement.

OBJECTIVETo explore the effects of integrative medicine (IM) rehabilitation protocolon motor function, activity of daily living, and quality of life (QOL) in hemiplegia patients after stroke.

METHODSTotally 120 patients with post-stroke hemiplegia were allocated to four groups using sealed envalope drawing, i.e., the rehabilitation group, the Chinese medical treatment group, the acupuncture group, and the comprehensive rehabilitation group, 30 cases in each group. Based on routine rehabilitative training, patients in the Chinese medical treatment group, the acupuncture group, and the compre-hensive rehabilitation group received standardized treatment based on syndrome typing, Shi's Consciousness-Restoring Resuscitation acupuncture, Chinese herbs + acupuncture comprehensive rehabilitatino protocol, respectively. The treatmet cycle consisted of 4 weeks with 24-week follow-ups. Fugl-Meyer motor assessment (FMA), Modified Barthel Index (MBI), and Stroke-Specific Quality of Life Scale(SS-QQL), and safety assessment were taken as main effect indices before treatment, at week 4 of treatment, at week 12 and 24 of follow-ups, respectively.

RESULTSThere was no statistical difference in FMA score, MBI score, SS-QOL score among the four groups before treatment (P > 0.05). These scores were significantly improved in the four groups at week 4 of treatment, week 12 and 24 of follow-ups, respectively (P < 0.05). Besides, FMA score and SS-QOL score were significantly improved in the comprehensive rehabilitation group at each corresponding time point, as compared with other treatment groups (P < 0.05).

CONCLUSIONSThe comprehensive protocol could significantly improve motor function, activity of daily living in hemiplegia patients after stroke, and further improve their QOL. Its effect was better than other single treatment.

Coronary vasospasm is a rare diagnosis resulting in sudden arrhythmic cardiac arrest. We report a case of a healthy, non-smoking elderly woman resuscitated from arrhythmic cardiac arrest. She had persistent spontaneous coronary vasospasm, leading to right ventricular myocardial injury and failure, and shock. She responded quickly to intravenous normal saline bolus infusion, but had irreversible neurological sequelae. Additionally, she had atrial fibrillation preceding ischemic ventricular fibrillation, a rare finding in coronary vasospasm-related cardiac arrest. We suggest immediate coronary angiography of patients in sudden arrhythmic cardiac arrest with acute right ventricular failure for a prompt, accurate diagnosis and appropriate management of the coronary vasospasm.

OBJECTIVETo investigate the changes of the goblet cells in the intestine during the restitution process of the gut barrier after hemorrhagic shock.

METHODSForty-nine Sprague-Dawley rats with body weight of 250-300 g were divided into control group (n=7) and experimental group (n=42). Rats in the experimental group was further divided into 6 groups (n=7 each) according to different time point at 1, 3, 6, 12, 24, and 36 hours after hemorrhagic shock resuscitation. The specimens from ileum tissue were taken to observe the morphological chan ges of the intestinal mucosa. The number of goblet cells was determined by light microscope and/or electron microscope. The contents of trefoil factor family 3 (TFF3) of goblet cells were examined using GC-9A gas chromatographic instrument.

RESULTSAfter hemorrhagic shock, mucosal epithelial injury was obvious in the small intestine. Tissue restitution was found after 3 hours, and mostly established after 12 hours. Following tissue restitution,the denuded mucosal surface was covered intensively by goblet cells. The number of goblet cells on the intestinal mucosa was reduced significantly from 243+/- 13 at 1 h to 157+/- 9 at 24 h (r=- 0.910, P< 0.01), and returned to normal level at 36 h. In the experimental group, the content of TFF3 in the intestinal mucosa increased significantly at 12 hours, decreased, but was still higher at 24 hours (t=3.24, P< 0.05).

CONCLUSIONSThe goblet cells play a key role in the restitution of intestinal mucosa. High expression of TFF3 may facilitate the intestinal mucosal restitution in the early phase.

The study was purposed to investigate the effect of bone marrow graft collection on the composition of peripheral blood stem cell grafts in healthy donors after recombinant human granulocyte colony-stimulating factor (rhG-CSF) application in vivo. Sixty-two healthy donors were treated with rhG-CSF [5 microg/(kg.d)] injected subcutaneously for five consecutive days. Donors were divided into groups A and B, and 31 donors were there in each group. Bone marrow grafts and peripheral blood stem cell grafts were harvested on the day 4 and 5 respectively in group A. In group B, only peripheral blood grafts were collected on both the day 4 and 5. The quantities of the cell components, CD3(+), CD3(+)CD4(+), CD3(+)CD8(+), CD14(+), CD34(+) cells and CD3(+)CD4(-)CD8(-) T cells were determined by multi-color flow cytometry. The results showed that median counts of nuclear cells (1.56 x 10(5)), lymphocytes (8.56 x 10(4)), CD3(+) (6.12 x 10(4)), CD3(+)CD4(+) (3.38 x 10(4)), CD3(+)CD8(+) (2.27 x 10(4)), CD14(+) (3.83 x 10(4)), CD34(+) cells (744) and CD3(+)CD4(-)CD8(-) T cells (3588) per microliter of peripheral blood stem cell grafts in group A were similar to counts of nuclear cells (1.40 x 10(4)), lymphocytes (7.34 x 10(4)), CD3(+) (5.32 x 10(4)), CD3(+)CD4(+) (3.06 x 10(+)), CD3(+)CD8(+) (1.83 x 10(4)), CD14(+) (3.21 x 10(4)), CD34(+) cells (554) and CD3(+)CD4(-)CD8(-) T cells (3120) in group B (p > 0.05). There were no difference in the ratios of CD4(+) cells/CD8(+) cells, CD14(+) cells/CD3(+) cells and CD3(+)CD4(-)CD8(-) T cells/CD3(+) cells in peripheral blood stem cell grafts between group A [1.52 (0.54 - 2.87)], [0.57 (0.15 - 1.64)], [0.064 (0.018 - 0.673)] and group B [1.68 (0.31 - 3.35)], [0.59 (0.18 - 1.25)], [0.063 (0.021 - 0.136)] (p > 0.05). It is concluded that no effect of bone marrow graft collection on the composition of peripheral blood stem cell grafts in the same donor is found after rhG-CSF application in vivo, bone marrow grafts and peripheral blood stem cell grafts can be collected respectively or simultaneously.

The study was aimed to analyze the difference of naive and memory CD4(+) and CD8(+) T-cell subsets between steady-state bone marrow (SS-BM) and recombinant human granulocyte colony-stimulating factor (rhG-CSF) mobilized peripheral blood grafts (G-PB). Four CD4(+) and CD8(+) T-cell subsets classified according to the expression of CD45RA and CD62L were determined by three-color flow cytometry. The results showed that the percentage of CD4(+), CD8(+) T-cell subsets and the ratios of CD4/CD8 in G-PB were significantly higher than those in SS-BM (p < 0.05). The percentage of CD4(+) naive T-cells in G-PB was significantly lower than that in SS-BM (p < 0.001). As compared with SS-BM, the percentage of CD4(+) effector memory T-cells was significantly high in G-PB (p < 0.001). There were no significant differences in the percentages of the four CD8(+) T-cell subsets between SS-BM and G-PB (p > 0.05). The percentage of CD4(+)CD62L(+) T-cells in G-PB was significantly lower than that in SS-BM (p = 0.001). The absolute numbers of CD4(+) and CD8(+) T-cell subsets, the eight naive and memory CD4(+) and CD8(+) T-cell subsets were significantly higher in G-PB than those in SS-BM (p < 0.001). It is concluded that the difference of naive and memory CD4(+) and CD8(+) subsets between G-PB and SS-BM may partially explain why the incidence and severity of acute graft-versus-host disease (GVHD) was similar and the incidence of chronic GVHD was different after transplantation with SS-BM or G-PB.

OBJECTIVETo investigate the optimal time for second allogeneic peripheral blood stem cell grafts (PBSC) harvest from healthy donors after in vivo recombinant human granulocyte colony-stimulating factor application (rhG-CSF).

METHODSThirty-eight healthy donors of second collection (group A) were treated with subcutaneous rhG-CSF \[5 microgxkg(-1)xd(-1)\] for five consecutive days and followed by leukapheresis on day 5 and 6. The control group (group B) was thirty-eight healthy donors who had received a first PBSC collection previously. Group A was reclassified as group C (< or = 9 months) and group D (> 9 months) according to the 75% quantile of interim time between first and second collection. The quantities of lymphocytes of CD3(+), CD3(+)CD4(+), CD3(+)CD8(+), CD14(+), CD34(+) cells and CD3(+)CD4(-)CD8(-) T cells were determined by multi-color flow cytometry.

RESULTSThe median number of CD3(+)CD8(+) (25.51 x 10(8)) and CD34(+) cells (0.51 x 10(8)) in group A were significantly lower than that (31.55 x 10(8) and 0.70 x 10(8) respectively) in group B (P < 0.05), and so did the CD3(+)CD8(+) (23.42 x 10(8)) and CD34(+) cells (0.42 x 10(8)) in group C than that in group B (P < 0.05). There was no statistical difference in median numbers of T cell subsets, monocytes, and CD34(+) cells between group B and group D (P > 0.05). The cell ratios of CD4(+)/CD8(+), CD14(+)/CD3(+) and CD3(+)CD4(-)CD8(-) T/CD3(+) in PBSC in group A, group C, and group D were similar to that in group B (P > 0.05). Sperman analysis showed a positive correlation between the total CD34(+) cells in second collection and the interval time from first to second collection (r = 0.357, P = 0.028).

CONCLUSIONNine months after the first collection maybe an optimal time for the second PBSC collection. For those who undergo second PBSC collection within 9 months, more circulation blood should be extracted to ensure enough immunological and hematopoietic compositions.
