BACKGROUND:It is controversial whether bone marrow mobilization can retain in cardiac injured position in congestive cardiomyopathy or differentiate into cardiomyocytes and vascular endothelial cells.
OBJECTIVE:To study the effects of granulocyte colony stimulating factor (G-GSF) on myocardium and angiogenesis in rats with congestive cardiomyopathy.
METHODS:Fifty Wistar rats with heart failure caused by adriamycin-induced cardiomyopathy were divided into heart failure group (n=20) treated with normal saline and bone marrow mobilization (n=30) treated with subcutaneous injection of recombinant human G-GSF. Ten rats from the bone marrow mobilization were kil ed at day 6 of mobilization, and myocardial tissue was taken for CD43 immunofluorescent staining. Blood samples were taken from the rat tail in each group before and 5 days after treatment to count total number of white blood cells and percentage of mononuclear cells. Meanwhile, mononuclear cells extracted from the peripheral blood were used for flow cytometry detection. At day 5 after treatment, bromodeoxyuridine (BrdU, 50 mg/kg) was successively given to al rats for 4 weeks before they were sacrificed. Myocardial tissues were taken to determine the homing of mononuclear cells and evaluate differentiation of mononuclear cells into cardiomyocytes and vascular endothelial cells using BrdU staining, BrdU/myosin heavy chain double staining, and BrdU/actin double staining. Hematoxylin-eosin staining was used for determination of blood vessel density.
RESULTS AND CONCLUSION:G-CSF mobilization increased the number of mononuclear cells that was significantly higher than before treatment (P<0.05). Flow cytometry showed that the number of CD34-positive mononuclear cells in the peripheral blood was higher in the bone marrow mobilization than in the heart failure group (P<0.05). Myocardial CD34 immunofluorescence showed that the heart failure group was negative and the bone marrow mobilization group was positive. In the bone marrow mobilization group, the myocardial tissue was positive for BrdU staining, BrdU/myosin heavy chain double staining and BrdU/actin double staining, while vascular endothelial cells in the region of myocardial injury was positive for BrdU;conversely, the heart failure group was negative. The density of blood vessels in the bone marrow mobilization group was significantly higher than that in the heart failure group (P<0.001). These findings indicate that bone marrow mobilization increases the number of mononuclear cells, and these cells are homing to myocardial injury, thereby playing a repair role in the myocardium and vascular tissue of heart failure rats with congestive cardiomyopathy.

BacKground:Helicobacter pylori ( Hp ) infection is an important etioIogicaI factor of gastric uIcer. AIthough eradicating Hp can heIp gastric uIcer heaIing,there is stiII a high recurrence rate of gastric uIcer. Therefore,other factors pIaying a roIe in the pathogenesis of gastric uIcer shouId be in concern. Aims:To investigate the non-reinfectious recurrence factors of gastric uIcer after Hp eradication. Methods:A totaI of 164 newIy diagnosed gastric uIcer patients with Hp infection from January 2011 to June 2012 at Ren Ji HospitaI,SchooI of Medicine,Shanghai Jiao Tong University were enroIIed. AII patients were given Hp eradication therapy and treatment of gastric uIcer. Patients with successfuI Hp eradication and heaIing of gastric uIcer were foIIowed up at 3,6,12 months after uIcer heaIing. Suspected risk factors of gastric uIcer recurrence were coIIected,and their reIationships with recurrence were anaIyzed. Results:A totaI of 123 patients positive for Hp infection compIeted the 12 months foIIow-up,gastric uIcer recurred in 18(14. 6%)of them. Chi-square test reveaIed that age,gender,smoking/drinking,non-steroidaI anti-infIammatory drugs( NSAIDs ),negative emotions and unheaIthy eating habits were significantIy associated with the recurrence of gastric uIcer(P<0. 05). Of the unheaIthy eating habits, irreguIar eating, and preference of indigestibIe food and fast food/carbonated drinks were significantIy associated with recurrence of gastric uIcer( P <0. 05 ). Conclusions:Patients with gastric uIcer shouId change their unheaIthy Iiving habits,foIIow rationaI use of drugs,and keep heaIthy mentaI status and eating habits for avoiding the recurrence of gastric uIcer.

Abstract: Objective To explore the relationship between peripheral blood and pleural effusion tuberculosis (TB)
infection effector T cells, and to further evaluate the value of combined pleural effusion adenosine deaminase (ADA) for rapid
diagnosis of tuberculous pleurisy. Methods The test data of 80 cases of tuberculous pleurisy and 70 cases of nontuberculous
pleurisy treated in the Sixth People's Hospital of Nantong City from January 2017 to December 2020 were analyzed. The TBinfected effector T cells were also detected simultaneously in the peripheral blood and the pleural effusion by the T-SPOT
technique, and the pleural effusion ADA was detected by the rate method. The subject operating characteristic curve (ROC) was
applied to take the optimal pleural effusion ADA threshold to compare the sensitivity and specificity of different critical values.
Person phase analysis was applied to analyze the correlation between peripheral blood and pleural effusion T-SPOT.TB. Data of
peripheral blood, pleural effusion T-SPOT.TB and ADA were integrated. Results When pleural effusion ADA>45 U/L, the
sensitivity and specificity for the diagnosis of tuberculous pleurisy were 50.0% and 94.3%, respectively; when ADA > 25.15 U/
L, the sensitivity and specificity were 80.0% and 72.9%. When ADA > 45 U / L, pleural/ blood T-SPOT.TB spot ratio (spot
forming cells, SFCs) > 2 times, the specificity for the diagnosis of tuberculous pleurisy was 100% (highest); when 25.15 U/L<
pleural effusion ADA ≤ 45 U/L, pleural/blood T-SPOT.TB spot ratio > 2 times, the specificity for the diagnosis of tuberculous
pleurisy was 92.3% (second). When pleural effusion ADA ≤ 25.15 U/L, and the pleural effusion/blood T-SPOT.TB spot number
ratio > 2 times, with 83.3% specificity (the lowest of the three groups). Conclusions The level of pleural effusion ADA is one
of the most used methods for diagnosing tuberculous pleurisy. Further combination of pleural effusion and blood T-SPOT.TB, if
the ratio of pleural effusion / blood T-SPOT. TB spots is greater than 2 times, it can further improve the diagnosis rate of
tuberculous pleurisy.
