Objective To investigate the effects on pancreas islet function in patients ubdergoing laparoscopic myomectomy during sevoflurane or propofol anesthesia.Methods Forty pa-tients,40-55 years,ASA Ⅰ or Ⅱ scheduled for elective surgery of laparoscopic myomectomy were randomly divided into two groups (n=20 each group).Propofol 2 mg/kg,sufentanil 0.5 μg/kg and rocuronium 0.9 mg/kg were used for induction,BIS was controlled between 40 and 55 during surgery.The anesthesia was maintained with sevoflurane and MAC was maintained with 0.7-1.3 in group S.The anesthesia was maintained with propofol continuous infusion and the plasma concentra-tion of target was set between 2.0 to 5.0μg/ml in group P.Blood glucose,insulin,c-peptide,gluca-gon and cortisol were measured at 3 time points:before induction of anesthesia (T0 ),start of surgery (T1 ),end of surgery(T2 ).Results Compared with T0 ,blood glucose,insulin,c-peptide,glucagon and cortisol in two groups were increased significantly at T1 and T2 (P <0.05).Compared with T1 , blood glucose,insulin,c-peptide,glucagon and cortisol in two groups were increased significantly at T2 (P <0.05).Compared with group S,blood glucose,glucagon and cortisol were increased indis-tinctively and insulin,c-peptide were increased significantly in group P at T1 and T2 (P < 0.05). Conclusion Compared with sevoflurane,propofol could promote the secretion of insulin and c-pep-tide,and inhibit cortisol and glucagon secretion,thus inhibit the rise of intraoperative blood glucose.

BACKGROUND: Previous studies found that C57BL/6 mouse was susceptible to atherosclerosis, while BALB/c mouse was resistant to atherosclerosis. The stenosis of the culprit vessel and the severity of myocardial infarction were correlated to the levels of OX40L expression. Whether OX40L has differential expression between C57BL/6 and BALB/c mouse was not identified.OBJECTIVE: To observe the differential expression of OX40L mRNA and protein in C57BL/6 and BALB/c mouse.METHODS: Total RNA and protein were extracted by Trizol and RIPA Buffer from heart, brain, kidney, skeletal muscle and spleen tissues of C57BL/6 and BALB/c mice. RT-PCR and Western Blot were used to detect OX40L mRNA and protein expression in heart, brain, kidney, spleen and skeletal muscle of two kinds of mice. The differential expression of OX40L mRNA and protein between C57BL/6 and BALB/c mice was observed.RESULTS AND CONCLUSION: RT-PCR results showed that the mRNA expression level of OX40L in heart of C57BL/6 mice mouse was significantly higher than BALB/c mice (P ＜ 0.05); the mRNA expression level of OX40L in spleen of BALB/c mice was significantly higher than C57BL/6 mice (P ＜ 0.05). There were no significant differences in the brain, kidney and skeletal muscle between these two strains. The results of Western Blot showed that the protein expression level of OX40L in heart, brain and kidney of C57BL/6 mice were significantly higher than BALB/c mice (P ＜ 0.05). There were no significant differences in skeletal muscle and spleen between these two strains. The OX40L mRNA transcription level in heart was higher in C57BL/6 mouse than BALB/c mouse, while the expression in spleen was lower than the latter. The OX40L protein levels in C57BL/6 mouse heart, brainand kidney were higher than BALB/c mouse. The differences of OX40L expression between the two strains of mice indicated that OX40L may promote to C57BL/6 mouse susceptible to atherosclerosis.

Objective To observe the efficacy of different degrees of portal vein ligation on portal pressure and liver regeneration of the unligated lobe in rats.Methods Seventy-two healthy male SpragueDawley rats were randomly divided into three groups:group A (sham,n =24);group B (n =24) undergoing 70％ portal vein ligation;group C (n =24) undergoing 90％ portal vein ligation.And then the portal pressure and liver regeneration rate (HRR) of the unligated lobe were detected immcdiately and postoperatively at each observation time point in each group.The serum alanine aminotransferase (ALT),aspartate aminotransferase (AST),hepatic proliferating cell nuclear antigen (PCNA) were compared at each observation time point,and the histological changes were observed by HE staining.Results The HRR of the unligated lobe in group B and group C increased obviously postoperatively at each time point,and the HRR in group C was significantly higher than that in group B [(220.1 ± 4.3) ％,(246.3 ± 5.6) ％,(261.4 ±2.3)％ vs (128.2 ±3.7)％,(143.4 ±8.7)％,(150.7 ±7.0)％,P＜0.05].The serum ALT and AST increased obviously on day 1 and then gradually declined,and the serum ALT and AST in group C was significantly higher than those in group B on day 1 [(821.7 ± 158.3) U/L,(1 372.0 ± 376.2) U/L vs (398.6 ± 80.4) U/L,(860.4 ± 80.0) U/L,P ＜ 0.05].The immediate portal pressure in both groups were obviously increased postoperatively and then gradually declined,and the portal pressure in group C was higher than that in group B at each observation time point [(23.5 ± 1.1)cmH2O,(18.8 ±0.9)cmH2O,(17.8±1.0)cmH2O,(16.6 ±1.0)cmH2O,(15.9±1.3)cmH2O vs (17.4 ±1.0)cmH2O,(16.5 ±1.2)cmH2O,(15.3±1.0)cmH2O,(10.2±1.2)cmH2O,(10.0±1.1)cmH2O,P＜0.05].ThePCNA index in group C was higher than that in group B on day 1 and3 [(21.5 ±1.1)％,(28.2±1.3)％ vs (12.8 ± 2.1) ％,(18.8 ± 1.9) ％,P ＜ 0.05].More foca1 necrosis of the unligated lobe were observed in group C on day 1,which were more than those in group B.Conclusion Higher degree of portal vein ligation could cause higher portal pressure,which leads to the greater regeneration of the unligated lobe.

Objective To investigate the alterations and phenotypes of dendritic cells, inflamma-tory monocytes and macrophages in immunocompetent mice during Pneumocystis murina ( P.murina) infec-tion for further analysis of the function of these cells during P.murina infection.Methods Wild type male C57BL/6 mice at age 6-8 weeks were randomly divided into two groups including the group with P.murina infection and the group receiving sham surgery.The mice without any intervention were used to set up the blank control group.The loads of P.murina strains in lung tissues of each mouse were quantified by TaqMan real-time fluorescence polymerase chain reaction after the infection.Histopathological examination was per-formed to evaluate the degree of inflammation in lung tissues.The numbers of dendritic cells, inflammatory monocytes and macrophages in lung tissues, peripheral blood and bone marrow samples, and the changes of inflammatory monocytes in spleen tissues were measured by flow cytometry analysis.The expression of major histocompatability complexⅡ(MHCⅡ), CX3C chemokine receptor 1 (CX3CR1) and CC chemokine re-ceptor 2 ( CCR2 ) by dendritic cells, inflammatory monocytes and macrophages in lung tissues during P.murina infection were analyzed by flow cytometry analysis.All of the data were collected one, two, three and four weeks after the corresponding treatments.Results The loads of P.murina strains in P.murina in-fected mice were elevated after two and three weeks infection, but decline at week 4 (P>0.05).Significant pathological changes including the alveolar destruction, inflammatory cell infiltration and thickened alveolar septum in mice with P.murina infection were observed under a microscope at week 3 and week 4.Compared to the sham surgery treatment group, the number of CD11c+CD11b+dendritic cells were increased in lung tissues, but decreased in blood samples during P.murina infection ( P<0.05) .The levels of inflammatory monocytes in blood samples fell at week 3 and then rose at week 4 during P.murina infection (P<0.05). No significant difference with the change of macrophages in mice was observed during P.murina infection ( P>0.05).The CD11c+CD11b+dendritic cells in lung tissues of mice with P.murina infection expressed high levels of MHCⅡand CX3CR1, and low levels of CCR2.The inflammatory monocytes in lung tissues of mice expressed high levels of CCR2, moderate levels of MHCⅡand low levels of CX3CR1 during P.murina in-fection.High levels of CX3CR1 and low levels of MHCⅡ and CCR2 were observed in macrophages from lung tissues of mice with P.murina infection.Conclusion Highly expressed CD11c+CD11b+dendritic cells and MHCⅡwere detected in lung tissues of mice during P.murina infection, indicating that CD11c+CD11b+dendritic cells were involved in the host defense against P.murina infection.

This study investigated the effect of puerarin on human umbilical vein endothelial cells (HUVEC) injured with hydrogen peroxide (H₂O₂). HUVEC were divided into three groups: a control group, a model group (H₂O₂ 400 μmol·L^-1) and a puerarin-treated group (3, 10, 30 and 100 μmol·L^-1). HUVEC were cultured with varied concentration of puerarin for 2 h and treated with H₂O₂ for another 24 h. Cell proliferation was detected by a CCK-8 assay. The mitochondrial membrane potential was measured by a JC-1 fluorescent probe. A transwell chamber assay was adopted to observe cell migration ability. Mitochondrial respiratory function was measured in a two-chamber titration injection respirometer (Oxygraph-2k). The expression of interleukin-1β (IL-1β), interleukin-18 (IL-18) and tumor necrosis factor-α (TNF-α) was detected by quantitative real-time PCR. The expression of pyroptosis-mediated proteins, including cleaved-cysteinyl aspartate-specific proteinase-1 (caspase-1), N-gasdermin D (N-GSDMD), NOD-like receptor protein 3 (NLRP3) and purinergic ligand-gated ion channel 7 receptor (P2X7R) was detected by Western blot. The results show that 400 μmol·L^-1 H₂O₂ treatment for 24 h causes obvious damage to HUVEC. Compared with the model group, puerarin protected against cellular injury in a dose-dependent manner, with the greatest effect at a dose of 30 and 100 μmol·L^-1. Puerarin significantly decreased the mitochondrial membrane potential and improved mitochondrial function. Puerarin inhibited cell migration induced by H₂O₂, suppressed the expression of IL-1β, IL-18 and TNF-α, and down-regulated the pyroptosis-mediated protein. These changes are statistically significant (P < 0.05). These findings demonstrate that puerarin has a protective effect against H₂O₂-induced oxidative damage of HUVEC by inhibiting the migration of HUVEC cells. The mechanism may be related to improved mitochondrial respiratory function and inhibition of pyroptosis.

An absorbable hemostatic material based on polysaccharide was prepared. The concentration of blood cells and coagulation factors was increased by reducing the water content in the blood, so as to reduce the coagulation time and achieve the purpose of rapid hemostasis. The specific surface area of starch was increased by using hydrochloric acid to hydrolyze potato starch, which made it easier to combine with α-amylase and increased the degradation rate. Starch was crosslinked into microspheres by crosslinking agent, which made the particle size uniform and greatly improved the water absorption. The surface modification of crosslinked starch microspheres with carboxymethyl group can further improve the water absorption of hemostatic materials. The results showed that the water absorption rate of our hemostatic material was more than 800%, and the average hemostatic time in the animal model was 138.7s. Compared with the imported products on the market, our hemostatic material have better hemostatic performance.
