The role of oxygen free radicals in multiple system organ failure (MSOF) was studied in rats produced by reticuloendothelial system blockade in addition to hemorrhagic shock. In MSOF animals blood reduced glutathione (GSH) elevated to 4.17?0.38 mg/g Hb at day 2, compared with baseline 2.67?0.09. Plasma glutathione peroxidase declined to 1.22?0.27 U/ml?min at day 1, and gradually increased at day 2 and day 3, but still lower than baseline 3.08?0.20. Blood superoxide dismutase (SOD) level was 182.6?27.1 at day 1, lower than baseline 249.5?72.4 ?g/g Hb. Plasma malondialdehyde (MDA) increased twice the normal level of 6.54?31 nmol/ml. Correlation analysis showed that lung index, plasma GPT and creatinine negatively correlated with the level of lung and liver homogenate SOD and kidney homogenate GSH, respectively.Results indicate that there are significant changes in the levels of blood and tissue antioxidants and lipid peroxides during MSOF. Organ failure appears to be correlated with the decrease in tissue antioxidation capacity.

Complement-induced polymorphonuclearcytes (PMN) aggregate in microvasculature of vital organs, produce microemboli, and block microcirculation blood flow. Activated PMN release oxygen free radicals, prostaglandins and proteases, in turn, damage endothelial and parenchyma cells. This is an important factor in pathogenesis of multiple system organ failure. We have found that Sinomeuine and Sodium Ferulate prevented PMN aggregation induced by activated complement. Adding the drugs into PMN suspension treated with cytochalasin B, the zymosan activated plasma, PMN aggregation was prevented. The changes of light transmission were smaller than those of control without drugs recorded with platelet aggregometer. The 50% of PMN aggregation inhibition with Sinomeuine was 0.76mg/ml (1.gmmol/L), and 0.82mg/ml (3.8mmol/L) with Sodium Ferulate.

Complement activation induces polymorphonucleal neutrophilic leukocyte (PMN) aggregation in circulation causing microvascular occlusion. The activated PMNs release lysosome enzymes which damage the tissue. It might take an important part in shock and multiple organ failure. We pre-treated rat PMNs with sinomeuine, which was extracted and purified from the stem of Sinomeuium acufum Rehd et Wils. It was found to inhibit the morphological changes and lysosome enzymes release in PMNs activated with zymosanactivated plasma. With administration of sinomeuine PMNs remained a spherical shape, no apparent ruffling or cytoplasmic projection and less aggregation. Elastase and Nacetyl-?-D-glucosaminidase content in PMNs supernatant increased less.

Methods A total of 80 patients with multidrug-resistant pulmonary tuberculosis were selected from March 22, 2016 to March 22, 2017, and randomized groups were randomly divided into the observation group and the control group,40 cases in each groups . The observation group and the control group Intervention and routine care. Results Observation group of patients satisfaction score (97.92±1.24), compliance score (95.42±3.14), the incidence of adverse events (5.00%), reasonable nutrition rate (100.00%), prescribed medication rate (100.00%), don't do STH without authorization (100.00%), rate of quitting cigarettes, alcohol and drug withdrawal rate (95.00%), and regularly review rate (95.00%), the psychological function (97.53±1.22) and body function (96.18 ± 1.42) points (95.31±2.41), material life, social function (94.82± 3.42mm) were better than control group (P<0.05).Conclusion Individualized intervention in multidrug-resistant tuberculosis patients can improve drug compliance.

Objective To analyze implementation outcomes of the new health reform policy at a provincial hospital for the past six months.Methods Trend analysis,factor analysis and ratio analysis approaches were used in monthly surveillance,along with comparative study of the data before and after the reform,to probe into impacts of the new policy on hospital operations.Results Medical income increased by 22.09％,mainly contributed by volume growth (22.28％) of medical services; Medical income dropped by 0.16％ due to pricing policy factors; medicine proportion deceased by 4.84％; following the reform,the income per outpatient and inpatient increased by 12.32％ and 5.35％ respectively.Conclusion Following the drug zero profit policy and rise of the charging standards for medical treatment service at the hospital,the growth of total income mainly comes from growing volume of medical services instead of pricing policy factors.The new health reform is conducive to optimizing the hospital's income structure and raising value to doctors' technical service.

Objective To explore the effect of the JAK/STAT signal pathway on the apoptosis-related gene in the synovial tissue of rat rheumatoid arthritis (RA).Methods Fifty rat models of collagen-induced arthritis,whose arthritis index was more than 2,were divided into the model group,the low dose of AG490 group,the medium dose of AG490 group and the high dose of AG490 group.In addition,6 rats were treated intraperitoneal injection.Then,the arthritis index and the change of apoptosis-related genes were compared.Multiple-sample average was analyzed by single-factor x2 test and LSD-t or Tamhane's T 2 test were used for two-two comparison.Results The arthritis index of the model group increased evidently,and the apoptosis inhibitor Bcl-2,Bcl-xl gene and protein expression was up-regulated,which was significantly different when compared with that of the control group(0.931±0.035 vs 0.351±0.024,0.920±0.037 vs 0.271±0.029,0.322±0.047 vs 0.230±0.031 ).The expression of apoptosis promoting factor Bax wasslightly up-regulated.The blockage of JAK/STAT pathway cotld down-regulate the expression levels of the gene and protein of survivins Bcl-2 and Bcl-xl,and up-regulate the gene and protein expressions of Bax.Conclusion In the process of RA development,apoptosis inhibitor Bcl-2,Bcl-xl gene and protein expression is up-regulated.JAK/STAT signal transduction pathway regulates the apoptosis process.

This study examined the effect of IL-10 on immunoglobulin-like transcript (ILT4) expression of human monocytic leukemic cell line THP-1, especially the role of the ILT4 promoter activity. ILT4 promoter area was amplified by PCR, and was cloned into the eukaryotic expressing vector pGL3-Basic. The pGL3-ILTP obtained was tested by double endonuclease digestion and sequencing. Then, the recombinant plasmid was transfected into THP-1 cells by using lipofectamine. After culture with IL-10 for 12 h, the mRNA extracted from THP-1 cells was detected by RT-PCR and the protein was detected by FACS. The dual-luciferase reporter assay system was employed to detect the activity of ILT4 promoter with or without IL-10. The results showed that the activity of pGL3-ILTP was significantly increased and was more than ten times that of pGL3-Basic cells. After culture with IL-10 for 12 h, the expression of ILT4 protein and its mean fluorescence intensity (MFI) were increased. Moreover, the mRNA was remarkably higher than that of the control group. Dual-luciferase reporter assay revealed that ILT4 promoter was much more activated after being treated with IL-10. We were led to conclude that pGL3-ILTP containing ILT4 promoter was constructed successfully. The expression of ILT4 could be up-regulated by IL-10 both at the transcriptional and translational level. Furthermore, ILT4 promoter could be much more active after addition of IL-10. This study suggests that IL-10 up-regulates ILT4 expression on monocytes via increasing ILT4 gene promoter activity, which may have implication for inducing transplantation tolerance in clinical practice.
