OBJECTIVETo observe the protection effect of Ligustrazine Hydrochloride (LH) on coagulation reaction and inflammation reaction in single valve replacement patients with rheumatic heart disease undergoing cardiopulmonary bypass (CPB).

METHODSTotally 40 patients undergoing single valve replacement were recruited in the study and randomly assigned to the two groups, the treatment group and the control group, 20 in each group. In treatment group LH (3 mg/kg) was intravenously infused from the jugular vein. LH (3 mg/kg) was also added in the CPB priming. In the control group LH was replaced by equal amount of normal saline. Endothelial micro-particles (EMP) count was detected before CPB, 30 min after CPB, 1 h and 24 h after CPB finished. The coagulation reaction time (R), coagulation time (K), clotting formation velocity (alpha angle), maximum amplitude (MA), coagulation index (CI), platelet (PLT), hypersensitive C reactive protein (hs-CRP), IL-6, and IL-10 were detected before CPB, 1 h and 24 h after CPB finished.

RESULTSThere was no statistical difference in aorta arresting time, period of CPB, post-operative drainage volume, plasma transfusion volume, post-operative respirator assistant time, and hospitalization time between the two groups (P >0.05). Compared with pre-CPB in the same group, the count of EMP was much higher at 30 min after CPB and 1 h after CPB finished (P < 0.01). R and K, hs-CRP, IL-6, and IL-10 increased at 1 h and 24 h after CPB finished (P <0.01,P < 0.05). The alpha angle,.MA, CI, and PLT decreased 1 h after CPB finished (P <0.01). The a angle increased, while CI and PLT decreased 24 h after CPB finished (P <0.05). Compared with the control group in the same period, the count of EMP was lower in the treatment group 30 min after CPB and 1 h after CPB finished (P <0. 05, P <0. 01). R and K values obviously decreased in treatment group 1 hour after CPB finished (P <0. 05), while a angle, MA, CI, and PLT increased (P <0. 05, P <0. 01). hs-CRP and IL-6 decreased in the treatment group 1 h and 24 h after CPB finished (P <0.05), while IL-10 increased (P <0.05). The count of PLT increased 24 h after CPB finished in the treatment group (P <0. 05).

CONCLUSIONLH had certain protection effect on the vascular endothelium undergoing CPB, and lower excessive activation of coagulation reaction and inflammation reaction in patients undergoing CPB.

Mesenchymal stem cells(MSCs) have functions such as immune regulation and tissue damage repair, but the specific mechanisms of their effects need to be further studied. Paracrine effect is an important mechanism for MSCs to achieve immune regulation, relieve inflammation and repair tissue damage. Tumor necrosis factor α(TNF-α) stimulated protein 6(TSG-6) is one of the paracrine factors of MSCs, which has significant inflammation inhibitory capability and tissue repair ability. It is an important cytokine of MSCs to exert their anti-inflammatory and anti-fibrotic effects. The MSCs can repair tissue damage in kidney, peritonea, skin, liver, lung, cornea, nervous system, and colon by secreting TSG-6. This powerful repair ability could be attributed to the ability of TSG-6 to inhibit the secretion of pro-inflammatory cytokines and pro-fibrogenic factors, such as TNF-α, interleukin(IL)-6, IL-1β and transforming growth factor-β1, thereby reducing the inflammatory response and fibrosis of the body.

Pulmonary fibrosis is an interstitial lung disease caused by different pathogenic factors. It has the characteristics of high morbidity and poor prognosis, which seriously affects the quality of life of patients. However, its pathogenesis has not yet been fully elucidated. Surfactant protein(SP)-A and SP-D are lipoprotein complexes distributed at the air-liquid interface of alveoli, synthesized and secreted by alveolar type Ⅱ epithelial cells and bronchiolar cells. They are important parts of the innate immune system, which participate in the host defense process through a variety of regulatory methods, and play an important role in regulating cell apoptosis and lung inflammation, promoting the process of epithelial repair and maintaining the stability of alveolar structure. The disorder and mutation of SP-A and SP-D may be the influencing factors of the pathogenesis of pulmonary fibrosis. Serum SP-A and SP-D levels are differentially expressed in patients with pulmonary fibrosis and normal healthy individuals, and are related to the severity of pulmonary fibrosis. They are considered to be a class of biomarkers that sensitively reflect lung epithelial cell damage and can be used in the diagnosis, treatment and prognostic evaluation of pulmonary fibrosis.

OBJECTIVE: To explore the mechanism of bone marrow mesenchymal stem cells(BMSCs) in alleviating silica-induced lung injury in mice. METHODS: Ten specific pathogen free healthy male C57 BL/6 mice were selected for isolating BMSCs and bone marrow macrophages(BMDMs). Transwell chamber was used, BMDMs were inoculated onto the upper chamber and BMSCs in the lower chamber. We divided them into sequencing control group and silica(SiO_2) exposure group. All cells were pre-stimulated with 50 μg/L mass concentration lipopolysaccharide for 4 hours. In the SiO_(2 ) group, 250 mg/L mass concentration SiO_2 was added to the upper chamber of transwell and cultured for 16 hours. Total RNA was extracted from the BMSCs collected from the lower chamber. HiSeq/MiSeq high-throughput sequencing technology was used to detect the BMSCs RNA paired-end sequencing. Transcriptome sequencing data was obtained and bioinformatics analysis was performed. Another 12 specific pathogen free healthy male C57 BL/6 mice were randomly divided into control group and experimental group. All mice received one intra-tracheal injection of 20.0 μL(250 g/L mass concentration) of silica dust suspension. After 6 hours, the mice in the control group was given 500.0 μL of 0.9% sodium chloride solution and mice in the experimental group was given 500.0 μL of BMSCs suspension(cell density 1×10~9/L) by tail vein infusion.Mice were sacrificed 12 hours later. The relative mRNA expression of interleukin(IL)-1 Ra, IL-10, tumor necrosis factor stimulating gene 6(TSG-6) and prostaglandin E2(PGE2) in lung tissues of mice were measured by quantitative real-time PCR(q-PCR). Meanwhile, BMDMs and BMSCs transwell co-culture models were established. The cells were divided into 5 groups: BMSCs group, BMSCs+BMDMs group, BMSCs+BMDMs+ lipopolysaccharide(LPS) group, 50 mg/L SiO_2 group, and 100 mg/L SiO_2 group. After 16 hours of corresponding SiO_2 stimulation, BMSCs of each group were collected and the relative mRNA expression levels of IL-1 Ra, IL-10, TSG-6, and PGE2 in the cells were detected by q-PCR. RESULTS: Compared with sequencing control group, BMSCs co-cultured with SiO_2 had 19 genes up-regulated and 21 genes down-regulated, including 10 genes up-regulated for more than 2.0-fold. The relative mRNA expression of IL-1 Ra, IL-10, PGE2 and TSG-6 in the lung tissue of mice increased in the experimental group than that of the control group(all P<0.05). The relative mRNA expression of TSG-6 increased by 37.5 times higher than that of the control group. Compared with the BMSCs+BMDM+LPS group, the level of TSG-6 mRNA relative expression increased in both the 50 mg/L SiO_2 group and the 100 mg/L SiO_2 group(all P<0.05). CONCLUSION: TSG-6 could be the key factor of BMSCs that can attenuate silica-induced lung injury.

OBJECTIVETo explore the mechanism of occupational medicamentosa-like dermatitis (OMDT) induced by trichloroethylene (TCE) and some immunity indexes in workers occupationally exposed to TCE.

METHODSThe blood samples from 8 cases with medicamentosa-like dermatitis in 1st, 2nd, 3rd, 4th and 5th weeks after admitting to hospital were examined for liver function, immunoglobulin and some complement indexes. Thirty nine workers occupationally exposed to TCE were investigated for urinary TCE and some immuno-complement indexes. The TCE concentrations of air in workplaces were monitored.

RESULTSC3d-CIC and C3 of patients before admission were (92.86 ± 44.80) mg/L and 0.91 ± 0.19 mg/L, respectively. C3d-CIC and C3 of patients before discharge were (52.41 ± 17.75) mg/L and (1.14 ± 0.22) mg/L, respectively. There were significant differences between admission and discharge (P < 0.05). The average TCE concentration in 4 workplaces was (351.96 ± 36.72) mg/m(3), which was higher than the occupational exposure limits (OELs). The number of workers exposed to the TCE concentration-time weighted and TCA in urine over OELs were 28.21% and 56.41% of total subjects, respectively. The serum IgG and CIC levels of patients before discharge were (10.03 ± 1.21) mg/L and 103.50 ± 29.17 mU/L, which were significantly lower than those (17.21 ± 1.85) mg/L and (227.46 ± 111.67) mU/L of patients before admission (P < 0.01).

CONCLUSIONThe type II and III hypersensitivity may be associated with OMDT and the organ injure induced by TCE.

OBJECTIVE: To explore the association of serum Apelin level, silicosis stage and lung function in patients with occupational silicosis(hereinafter referred to as silicosis). METHODS: A case-control study was conducted. A total of 85 patients with silicosis were selected as the silicosis group(44, 28 and 13 patients with stage Ⅰ, Ⅱ and Ⅲ silicosis, respectively), and 120 healthy individuals without occupational hazard exposure were selected as the control group. Serum samples were collected from the cases of the two groups and the level of Apelin was determined by enzyme-linked immunosorbent assay. The pulmonary function of the silicosis group was examined. RESULTS: The median and the 25 th and 75 th percentiles \[M(P_(25),P_(75))\] of serum Apelin levels in the control group and silicosis group were 1.29(0.92, 1.77) and 0.80(0.62, 1.04) mg/L, respectively. The level of serum Apelin M(P_(25),P_(75)) in stage Ⅰ, Ⅱ and Ⅲ silicosis patients was 1.03(0.82, 1.31), 0.66(0.60, 0.80) and 0.50(0.30, 0.65) mg/L, respectively. The results of multiple linear regression analysis showed that the level of serum Apelin in the silicosis group was higher than that in the control group after excluding the influence of age and smoking(P<0.01). The level of serum Apelin decreased with the increase of silicosis stage in the silicosis group(P<0.001). Serum Apelin level in silicosis group was positively correlated with lung vital capacity, forced vital capacity, forced expiratory volume in the first second, and forced expiratory flow between 25% and 75%(all P<0.05). CONCLUSION: The lower level of serum Apein in silicosis patients, the more serious the disease and the more serious the damage to lung function. Apelin is of significance in the diagnosis, staging, treatment appraisal and prognostic evaluation of silicosis, and it can be use as a potential therapeutic target for silicosis.

OBJECTIVETo evaluate the impact of preoperative three-dimensional visualization and virtual liver surgery planning on hepatic resection.

METHODSAll relevant structures (livers, portal vein, hepatic veins, and tumors) were extracted from multislice CT scans of 142 cases treated from May 2007 to May 2009. By the liver surgery planning system software Liv 1.0, reconstruction and image analysis of the relevant structures was performed and virtual resections of liver were carried out. Data were correlated to intraoperative findings.

RESULTS(1) Three-dimensional visualization revealed the spatial relationship of tumors to the intrahepatic vascular system, thus giving impressions how the neoplasms were situated. Virtual tumor resections corresponded to the intraoperative findings. (2) With the planning, an intended resection could be performed virtually and optimal identification of resection margins could be achieved. The ischemia and congestion territory within the remaining liver parenchyma could be calculated. Simulation resections could avoid liver parenchyma over resection and maintain a sufficient amount of liver tissue to sustain hepatic function. Virtual simulations of tumor resection were used successfully to plan of surgical procedures in the hepatic tumors. Hepatectomy was performed in 29 cases after virtual tumor resections but seemed impossible with conventional CT scan. Resection plans of 92 cases were optimized after virtual resections. (3) The mean liver volume of patients with primary hepatocellular carcinoma measured by the software and the real resected was (477 +/- 223) ml and (451 +/- 209) ml respectively. Comparison by means of linear regression analysis between volume measurement on the software and the real resected showed a nearly ideal correlation coefficient (R = 0.922, P < 0.01). The mean error was 6.1%.

CONCLUSIONSThe three-dimensional tumor visualization and virtual simulation of tumor resections of the software Liv 1.0 provide an important reference for a valuable planning of complex hepatic resections. It is not only benefit to improve the predictability and security of hepatectomy but also helpful to improve the success rate of complex hepatic resections.
