Objective To investigate the dynamic variation of subsets of myeloid derived suppressor cells (MDSC) and their ratio in septic mice, and to discuss their role in the development of sepsis. Methods Male C57BL/6 mice were randomly divided into sepsis model group and sham group according to random number table. Polymicrobial sepsis was induced by using cecal ligation and puncture (CLP), while mice in sham group only underwent laparotomy and laparorrhaphy without CLP. Thirty mice in each group were used to observe living condition, and the 20-day survival rate was compared between the two groups. In addition, subsets of MDSC in peripheral blood, spleen and bone marrow were analyzed with flow cytometry for other 60 mice (12 mice at each time point, as 0, 3, 7, 12 and 20 days). Spleens were harvested at 7 days for weighing, and single cell suspension of spleen tissue was prepared for splenocyte counting. Histopathologic changes in spleen tissue and liver tissue were observed under light microscope after hematoxylin and eosin (HE) stain. Results ① No mice died in sham group within 20 days after the operation. On the other hand, 10 mice in model group died within 20 days, and the difference in survival rate between the two groups was statistically significant (100.0% vs. 66.7%, χ2 = 11.861, P = 0.001). ② The spleens in model group showed obvious enlargement and significantly outweighed as compared with those in sham group (mg: 413.33±41.63 vs. 111.67±17.56, t = 11.564, P = 0.000), and the total count of splenocytes was significantly higher than that in sham group (×109/L: 21.20±2.43 vs. 1.87±0.06, t = 13.578, P = 0.005). ③ Pathological sections with HE staining showed that the liver tissue and spleen tissue remained normal in sham group. In model group, the hepatic tissue showed acute inflammatory reaction, including tissue disruption, capillary congestion, infiltration of neutrophils, marked edema of hepatocytes and focal hepatocellular necrosis. Abnormalities were also found in the spleen tissue: the red pulp and white pulp were disordered, splenic sinus was congested with numerous red cells, the splenic capsule thickened, immature myeloid cells with circular nuclei proliferated in the subcapsular region and perivascular region, splenic cord and splenic sinus were infiltrated with a large number of hematopoietic cells. ④ No significant changes in the monocytic MDSC (M-MDSC) and granulocytic MDSC (G-MDSC), and their ratio were found in peripheral blood, spleen and bone marrow at every time point in sham group. On the other hand, in model group, the ratio of M-MDSC and G-MDSC was continuously increased in peripheral blood, spleen and bone marrow, and M-MDSC only slightly decreased at 20 days. On the other hand, the ratio of M-MDSC/G-MDSC rose at first followed by a decrease. The ratio of M-MDSC/G-MDSC in peripheral blood was higher than 1 from 3 days after the operation, reaching the peak at 12 days (compared with 0 day: 4.16±0.53 vs. 0.79±0.11, P < 0.05), while the ratio of M-MDSC/G-MDSC in spleen and bone marrow after CLP were lower than 1 at all time points, reaching the peak on 7 days after the operation (compared with 0 day: 0.70±0.06 vs. 0.25±0.02 in spleen, 0.39±0.06 vs. 0.11±0.01 in bone marrow, both P < 0.05), and then gradually decreased afterwards. Conclusion Subgroups of MDSCs were continuously aggregated in the peripheral blood, spleen and bone marrow, and their ratio rose first and decreased afterwards along with the development of sepsis, and the changes may reflect the change of immune status at different stages of sepsis.

Objective To investigate the risk factors of in-stent restenosis (ISR) after coronary implantation of drug-eluting stent Methods One hundred and fifty-seven patients including 118 males and 39 females,who underwent successful implantation of drug-eluting stent, were recruited in the study. The patients were divided into the restenosis group (33 patients) and non-restenosis group ( 124 patients) according to the angiographic results. The associations of ISR with clinical and coronary angiographic characteristics were analyzed using univiriate analysis and logistic regression. Results In the restenosis group,there were 18 cases of diabetes mellitus ( 54. 5% ), 26 cases of frequency angina ( 78. 8% ), which were significantly higher than those of 31 cases of diabetes (25.0%) and 72 case of frequent angina (58. 1% ) in the non-restenosis group (χ2 = 10. 60, P < 0. 01, χ2 = 4. 77, P = 0. 03 for diabetes mellitus and frequent angina, respectively). Compared to non-restenosis group, the occurrence rates of chronic total occasion, bifurcatus lesions, diffuse lesions were significandy higher in the restenosis group ( 19. 3% vs 7. 6% χ2 =5.92,21.1% vs 10. 2% χ2 =4. 34,26. 3%vs 12. 1% χ2 =6. 32,Ps <0. 05). Fifty-seven stents were implanted into the restenosis group,and one hundred and fifty-seven into the non-restenosis group. Logistic regression analysis showed that diabetes, frequent angina,chronic total occlusion lesions, bifurcatus lesions, diffuse lesions, stent length and diameter were significantly associated with restenosis ( OR value were 3.52,2. 59,3.05,3. 14,3.08,0. 93,95% CI were 1.56 - 7.90,1.02 - 6. 59,1.11 - 8. 36,1.30 - 7.59,1.34 - 7.05,0. 88 - 0. 98 respectively, Ps < 0. 05 ). Conclusion After implantation of drug-eluting stent, diabetes mellitus, chronic total occasion lesions, frequent angina, diffuse lesions, bifurcatus lesions and stent length and diameter are associated with follow-up restenosis.

Objective To explore the effect of online health education by family physician using the wearable devices, and provide the basis in theory and practice to improve the level of primary health care in community. Methods A total of 132 community residents (78 for male and 36 for female, all of them are WeChat user) with hypertension in one residential area who had regularly participated in the activity of volunteer blood pressure measurement organized by community health service center in wujiaochang street from November 2015 to February were chosen as the participants. The residents who wore the wearable device given by the community hospital uniformly were set as the study group (60 people), while the remaining 72 residents were set as the control group. Both groups received the daily online health education provided by the family physicians through their smartphone. We compared the diversity of health cognition, controlling behavior and controlling results to blood pressure of both groups before and after the studyrelatively, then we comprehensively analyzed the effect of use of wearable devices in family physicians ' online health education. SPSS 18.0 was used for data analysis. The categorical data of two groups were compared with chi-square test and the comparison of continuous data was performed with t test. Results Totally 114 community residents were qualified in the study, and the initial backgrounds of study group and control group had no significant difference. After receiving the online health education information for three months, both groups achieved improvement on the cognition and related self-control behavior of hypertension except for several items, and the study group did better than control group in most items. The physical examination showed that the systolic blood pressure of the study group after the intervention [(131.46 ± 12.89) mmHg] (1 mmHg=0.133 kPa) was lower than before [(137.24 ± 12.27) mmHg] and the difference was significant (t=9.2, P<0.01); the diastolic blood pressure of the study group after the intervention [(78.29±8.91) mmHg] was lower than that of before intervention [(80.75±10.25) mmHg] and the difference was significant (t=2.3, P<0.05). Meanwhile, after intervention the systolic blood pressure of study group [(131.46 ± 12.89) mmHg] was lower than that of control group [(133.27 ± 12.7) mmHg] and the intervention was significant (t=2.1, P<0.05). Conclusion Long-term use of wearable devices help family physicians improve the effect of health education, consequently the community hospitals are responsible to enhance the input and management of the informatization of family physicians' service, and assist them to broaden the form and content of health education.

Objective To study the protein expression levels of matrix metalloproteinases (MMPs)and their inhibitors in bone tissues of rat femoral head and to explore the relationship between necrosis of femoral head and glucocorticoid.Methods Twenty healthy adult SD rats were randomly divided into glucocorticoid group and control group,with 10 rats in each.Glucocorticoid group was treated with intramuscular injection of hydrocortisone twice a week.The control group received normal saline of the same volume.Four weeks later,bone tissues of left femoral head were collected from each group of rats for HE determination of femoral head necrosis.The expressions of matrix metalloproteinase-1 (MMP-1 ), matrix metalloproteinase-2 (MMP-2 ), tissue inhibitor of matrix metalloproteinase-1 (TIMP-1 ),and tissue inhibitor of matrix metalloproteinase-2 (TIMP-2 )at mRNA and protein levels were detected by RT-PCR and Western blot techniques,respectively.Results The expressions of MMP-1 and MMP-2 at mRNA and protein levels were higher in glucocorticoid group than those in the control group. However,TIMP-1 and TIMP-2 gene and protein expression levels were lower in glucocorticoid group (all P<0.05). Conclusion The expressions of MMPs in bone tissues of rat femoral head in early necrosis were increased,but their inhibitors had decreased expressions. We can draw the conclusion that glucocorticoid-induced necrosis of femoral head may be related to its regulation of the expression levels of MMPs and their related inhibitors.
