Chinese Critical Care Medicine 2015;(2):138-142
ObjectiveTo observe the changes in plasma interleukin-33 (IL-33) in patients with sepsis and its regularity, the association between IL-33 and the infection, and the significance of IL-33 in predicting the prognosis of sepsis.Methods A prospective single-center single-blind clinical study was conducted. Forty patients with sepsis in intensive care unit (ICU) of Shengjing Hospital of China Medical University from May 2012 to January 2013 were enrolled. The patients were divided into general sepsis, severe sepsis and septic shock groups according to the severity of systemic infection and presence of organ dysfunction. The sepsis patients were again divided into 28-day death group and survival group. Ten healthy volunteers and 11 patients with systemic inflammatory response syndrome (SIRS) were enrolled as healthy control and SIRS groups. The levels of procalcitonin (PCT), IL-33, IL-6, IL-1β, tumor necrosis factor-α (TNF-α), and IL-33 receptor sST2 were determined with enzyme linked immunosorbent assay (ELISA) within 3 hours, and 24 hours and 5 days after enrollment to ICU. The acute physiology and chronic health evaluationⅡ (APACHEⅡ) score was calculated. The clinical outcome, length of stay in ICU, and duration of mechanical ventilation were recorded. The relationship between IL-33 and each parameter was analyzed by Spearman analysis. Receiver operating characteristic (ROC) curve was drawn to evaluate IL-33 in predicting the outcome of sepsis.Results Plasma IL-33 in sepsis patients within 3 hours after admission was significantly increased compared with that of the healthy controls and SIRS group (ng/L: 15.43±7.22 vs. 0.67±0.24, 1.25±1.09, bothP< 0.01). Compared with SIRS group, PCT in sepsis group was significantly increased [μg/L: 52.23 (19.69, 73.37) vs. 1.22 (0.69, 3.73),Z = -2.447,P< 0.001]. With exacerbation of illness, APACHEⅡ score, the values of PCT and IL-33 were gradually increased in general sepsis, severe sepsis and septic shock groups, while the length of stay in ICU and the duration of mechanical ventilation were gradually prolonged (P< 0.05 orP< 0.01). The concentration of IL-33 (ng/L) of sepsis patients admitted to ICU within 3 hours, and 24 hours and 5 days of the illness was 15.43±7.22, 11.82±6.16, 5.55±2.25, respectively (F = 4.823,P = 0.004). There was a positive correction between IL-33 within 3 hours after ICU admission and APACHEⅡ score (r = 0.351,P = 0.031), PCT (r = 0.412,P = 0.005), IL-6 (r = 0.535,P = 0.030), IL-1β (r = 0.674,P = 0.030), TNF-α (r = 0.250,P= 0.030), sST2 (r = 0.620,P< 0.001), and length of stay in ICU (r = 0.296,P = 0.013), duration of mechanical ventilation (r = 0.385,P = 0.011). Decreased plasma IL-33 level could be found in the survivors (n = 37,F = 7.798,P< 0.01), and its level in non-survivors (n = 3) was increased (F = 37.283,P> 0.05). The area under the ROC curve (AUC) of IL-33 and PCT in ROC curve were 0.821, 0.829. When the cut-off value of IL-33 was 13.79 ng/L, the sensitivity was 74.2%, the specificity was 79.6%; when the cut-off value of PCT was 4.70μg/L, the sensitivity was 87.5%, and the specificity was 81.4%.Conclusions The concentration of IL-33 3 hours after ICU admission was obviously increased in sepsis patients, and it was positively correlated with PCT, therefore it is valuable in the diagnosis of the infection. In addition plasma IL-33 is related to the severity of sepsis. Its trend of change is valuable in predicting the outcome and in distinguishing sepsis from SIRS.

China Pharmacy 2016;27(7):879-881,882
OBJECTIVE:To compare antidiuretic activity of Ootheca Mantidis before and after processing,and to explore the best medicinal part and mechanism of Ootheca Mantidis. METHODS:96 rats were randomly divided into blank group,model group,positive group,Ootheca Mantidis group,Ootheca Mantidis stir-fried with salt group,steamed Ootheca Mantidis group, crude product eggs and egg shell groups,processed product eggs and egg shell groups,with 8 rats in each group,12 groups in to-tal. Except blank group,other groups were given adenine 250 mg/kg,ig,for 4 weeks to induce kidney-yang and diuresis model. From third week,Ootheca Mantidis crude drug group and processed Ootheca Mantidis group were all given relevant medicine 0.11 g(crude drug)/ml i.g,and crude product eggs and egg shell groups and processed product eggs and egg shell groups were given rel-evant medicine,ig,once a day,by mass ratio of eggs to egg shell(cude drug 1∶2.4,salt stir-fried product 1∶1.7,steamed prod-uct 1∶2.1)for consecutive 4 weeks. The urinary volume,body weight,renal index and the serum contents of ADH and ALD were all determined. RESULTS:Compared with blank group,body weight and serum content of ADH and ALD decreased in model group,while renal index and urinary volume increased(P<0.05). After 4 weeks of treatment,compared with model group,body weight and serum content of ADH increased in Ootheca Mantidis groups,while urinary volume and renal index decreased (P<0.05);serum content of ALD increased in treatment groups;there was statistical significance in the serum content of ALD in those groups except Ootheca Mantidis group,Ootheca Mantidis stir-fried with salt group and steamed Ootheca Mantidis group (P<0.05);except for ALD,those index were in descending order of steamed Ootheca Mantidis group>Ootheca Mantidis stir-fried with salt group>Ootheca Mantidis group,and steamed Ootheca Mantidis shell group had best exchange. CONCLUSIONS:The an-tidiuretic activity of Ootheca Mantidis has been enhanced after processing. The egg shell of steamed Ootheca Mantidis is main me-dicinal part. To increase the serum content of ADH might be one of the main mechanism of arresting polyuria.

4.Pursue excellence of clinical research on chronic hepatitis B in China
Journal of Clinical Hepatology 2015;31(4):481-482
In China universal vaccination program against hepatitis B virus (HBV)in newborns has led to a dramatic decline in HBsAg prevalence from 9.75%in 1992 to 7.18%in 2006.However,it is estimated that there are still around 90 million patients with chronic HBV infection,including 20-30 million with chronic hepatitis B (CHB).As recommended therapies,interferons and nucleos(t)ide analogues can effectively suppress HBV replication and thereby halt the progression of liver disease.Unfortunately,the current standard of care could not cure CHB in most cases.Developing direct antiviral agents targeting the specific steps of HBV life cycle or immunotherapy against the key steps of immune response to HBV infection will ultimately enable us to cure CHB.Chinese hepatologists have published more and more papers on HBV prevention and management,with the aim of optimizing current modalities and exploring new therapies.Adopting the public health policy to improve the accessibility and affordability of preventive and therapeutic drugs and increase the coverage of vaccination and standardized treatment is the most effective means to reduce the enormous health and socioeconomic burden of HBV-related diseases.

Objective To investigate whether the high intensity focused ultrasound (HIFU) for treating uterine fibroids and adenomyosis leading to pelvic adhesion .Methods 1 672 patients with definitely diagnosed uterine fibroids or adenomyosis were col‐lected and divided into the non‐HIFU group(1 560 cases) and HIFU group(112 cases) according to whether performing HIFU op‐eration .The pelvic adhesion situation in each case was scored according to pelvic adhesion scoring system .Then the results were performed the statistical process .Results No statistically significant differences were observed in the pelvic adhesion situation and pelvic adhesion degree between the HIFU group and the non‐HIFU group (P>0 .05) .The single factor analysis of factors possibly causing pelvic adhesion showed that the age ,past history of endometriosis ,operation and pelvic inflammatory disease ,lesion size and dysmenorrhea history affected pelvic adhesion ,the differences were statistically significant(P<0 .05) .But in the multi‐factor corre‐lation analysis ,various factors in the HIFU group were excluded(P> 0 .05) ,while the operation history and pelvic inflammation disease history had correlation with pelvic adhesion (P<0 .05) .Conclusion HIFU dose not cause pelvic adhesion in treating uter‐ine fibroids and adenomyosis .
6.Chitosan nanoparticles enfolding antisense endothelin converting enzyme RNA expression plasmid and airway hyperresponsiveness in asthmatic mouse models
Chinese Journal of Tissue Engineering Research 2015;(43):6913-6917
BACKGROUND:Studies have reported that underin vitro experimental environment, antisense endothelin nucleic acid nanometer carrier can express target nucleic acid and produce RNA interference effect after enfolding by 12-alkylated chitosan nanoparticles, which can effectively inhibit the excessive generation of endothelin from inflammatory cytokines induced by alergen. OBJECTIVE:To investigate the effect of 12-alkylated chitosan nanoparticles enfolding antisense endothelin converting enzyme RNA expression plasmid on airway hyperresponsiveness in asthmatic mouse models. METHODS: Forty Balb/c mice were randomly divided into four groups: control, chitosan nanoparticles, normal saline and plasmid groups. Mice in the chitosan nanoparticles, normal saline and plasmid groups were subjected to sensitization by an intraperitoneal injection with ovalbumin (0, 14 days) and motivation by aerosol inhalation of ovalbumin (24, 25, 26 days) to induce asthma models. Mice in the control group were subjected to sensitization and motivation by the perfusion of normal saline. At 24hours before the first excitation, mice in the control, chitosan nanoparticles, normal saline and plasmid groups were perfused with normal salinevia airway, 12-alkylated chitosan nanoparticles, normal saline and antisense endothelin converting enzyme RNA. At 48 hours after the last excitation, the airway reactivity of mice was detected. After 28 days, bronchoalveolar lavage fluid cytology, lung histopathology, cytokines in spleen cel culture supernatant were detected. RESULTS AND CONCLUSION:Compared with the control group, the total number of plasmid cels, the percentage of eosinophils, eosinophil absolute counts, interleukin-4 levels, endothelin levels and airway hyperresponsiveness of mice in chitosan nanoparticles, normal saline and plasmid groups were increased (P < 0.05), and the lung inflammation was more severe. These indicators in the chitosan nanoparticles group were al lower than those in the normal saline and plasmid groups (P < 0.05) and the degree of inflammation was lighter than that in the saline and plasmid groups. These results demonstrate that 12-alkylated chitosan nanoparticles enfolding antisense endothelin converting enzyme RNA expression plasmid can reduce the synthetic amount of asthma endothelin and inhibit airway responsiveness.
7.Short-term prognostic implication for patients with ST-elevation myocardial infarction undergoing domestic rapamycin drug-eluting stent implantation
Chinese Journal of Tissue Engineering Research 2015;(12):1878-1883
BACKGROUND:Coronary drug-eluting stent implantation is the best treatment for acute ST-segment elevation myocardial infarction, but because of many combined risk factors in elderly patients, the mortality rate is increased with aging. OBJECTIVE:To analyze whether age differences is a significant independent predictor of in-hospital clinical outcomes in patients with acute ST-elevation myocardial infarction treated with domestic rapamycin drug-eluting stent implantation. METHODS:A retrospective analysis was done in 307 patients with first acute ST-elevation myocardial infarction treated with emergent rapamycin drug-eluting stent implantation for primary percutaneous coronary intervention. According to the age, there were three groups: non-elderly group (< 65 years old,n=175), low-elderly group (65-74 years old,n=83), and high-elderly group (≥ 75 years old,n=49). Clinical features, mortality, cardiac events during in-hospital stay were compared among three groups. RESULTS AND CONCLUSION: Compared with the non-elderly group, the proportion of female patients and the history of hypertension were higher in the low-elderly or high-elderly group (P < 0.05). The history of smoking was higher in the non-elderly group than the other groups (P < 0.05). The incidences of Kilip classification≥II, three-lesion or left main coronary artery disease were higher in the high-elderly group than the other groups (P < 0.05). Hemoglobin, total cholesterol, triglycerides, low-density lipoprotein, and cholesterol levels were higher in the non-elderly group than the other groups (P < 0.05). Serum creatinine level, incidence of malignant arrhythmia and incidence of in-hospital cardiac death were increased with aging. Successful reperfusion was higher in the high-elderly group than in the low-elderly or non-elderly group. Rate of acute heart failure and combined cardiovascular events were higher in the high-elderly group than in the low-elderly or non-elderly group (P < 0.05). Multivariate logistic regression analysis show that age is an independent risk factor for in-hospital mortality in patients with acute ST-elevation myocardial infarction treated with rapamycin drug-eluting stent implantation.
8.Telomerase reverse transcriptase genetic modification of bone marrow mesenchymal stem cells in diabetes treatment
Chinese Journal of Tissue Engineering Research 2015;(28):4549-4554
BACKGROUND:Pancreas or islet cel transplantation and stem cel transplantation bring hope to cure diabetes, but pancreas or islet transplantation appears to have a lack of donors as wel as immune rejection problems, limiting their clinical development. Therefore, stem cel transplantation therapy has become the current hotspot.
OBJECTIVE:To study the therapeutic effects of huaman telomerase reverse transcriptase (hTERT)-modified bone marrow mesenchymal stem cel s transplantation on diabetes mel itus in SD rats.
METHODS:Bone marrow mesenchymal stem cel s were transfected with PLXSN carrying hTERT. Thirty-six male SD rats were randomly divided into control group (n=6), stem cel group (n=10), hTERT transfection group (n=10), diabetes mel itus group (n=10). Except the control group, the rats were injected with stretozotocin (45 mg/kg) to make diabetes mel itus models. After modeling, rats in the stem cel group and hTERT transfection group were respectively intravenously injected with 1 mL of bone marrow mesenchymal stem cel s (1.5×1010/L) and 1 mL of hTERT-modified bone marrow mesenchymal stem cel s (1.5×1010/L).
RESULTS AND CONCLUSION:At 24 hours after modeling, the fasting blood-glucose level was significantly increased in the diabetes mel itus group, which was higher than the normal value (6.7 mmol/L). At 15 days after cel transplantation, the fasting blood-glucose levels were signficiantly decreased in the stem cel group and hTERT transfection group as compared with the diabetes mel itus group (P<0.05), but the body mass of rats was increased in these two group (P<0.05), especial y in the hTERT transfection group. At 45 days after cel transplantation, the fasting blood-glucose level and body mass in the stem cel group and hTERT transfection group were close to those in the control group (P>0.05), and moreover, the hTERT group had better outcomes than the stem cel group. Meanwhile, in the diabetes mel itus group, the fasting blood-glucose level was stil at a higher level, and the body mass decreased continously. These findings suggest that hTERT-modified bone marrow mesenchymal stem cel transplantation is effective for treatment of diabetes mel itus in rats.
