Objective:To investigate the concentration of pulmonary surfactant-associated protein D ( SP-D) and interleukin-8 (IL-8) in the bronchoalveolar lavage fluid (BALF) of ACOS patients undergoing mechanical ventilation (MV). Methods:38 patients with ACOS undergoing MV were involved in the study. According to the APACHEⅡscore, the patients were divided into the remission group (n=20) and the aggravation group (n=18). BALF was collected on the 1st and 5th days after MV. The content of IL-8 and SP-D in BALF was measured by ELISA. The levels of IL-8 and SP-D in BALF of the patients with different severity were compared. Results:The level of SP-D was significantly higher on the 5th day than on the 1st day in the remission group,and it decreased more ob-viously in the worsening group (P<0. 05). The level of IL-8 decreased gradually in the remission group but increased gradually in the worsening group. The level of SP-D was negatively correlated with IL-8 level and APACHEⅡ score. Conclusion:The findings suggest that the levels of SP-D and IL-8 in BALF are correlated with prognosis of ACOS patients undergoing MV,and it may prove to be useful as a guidance of therapy and prognosis.

Objective To investigate the infection of Xuebijing injection on inflammatory factor of large sized avulsion patients.Methods 70 patients being selected with large sized avulsion were randomly recruited into a treatment group(35 patients)and a control group(35 patients).The control group received traditional comprehensive treatment.On this basis,Xucbijing injection was injected to the treatment group on admission day,and Xuebijing injection 50 ml in 0.9%NaCl solution 100 ml was,intravenously infused for 60 min once,2 times daily,up to 7 d.TNF-α,IL-6,CRP,WBC and NEU%of the two groups were respectively detected before treatment and 7 days after the treatment.Exudation of wound surface was also observed.Results After 7 days of treatment,there was significant difierence in the treatment group compared with pretreatment(P＜0.01).There was statistical difference between two groups after 7 days of treatment(P＜0.01).Exudation of wound surface of the treatment group was less than the control group's.Conclusion Xuebijing injection has antagonistic effect on inflammatory factor of large sized avulsion patients and can lessen exudation of wound surface.

To achieve higher level expression of Interferon α2b (IFN-α2b) in methylotrophic yeast (Pichia pastoris), a cDNA fragment coding for the mature IFN-α2b was designed and synthesized based on the synonymous codon bias of P. pastoris and optimized G+C content. The synthetic IFN-α2b was inserted into the secreted expression vector pPICZαA, and then integrated into P. pastoris GS115 genome by electroporation. Multi-copy integrants in the Mut+ recombinant P. pastoris strain were screened by high concentrations of Zeocin. 120 hours culturing allowed expression of the IFN-α2b transformant up to 810 mg/L as detected by SDS-PAGE and quantitative methods. In addition, Western blot analysis showed that the recombinant proteins had immunogenicity. The significant antiviral activity of the recombinant IFN-α2b protein was verified by WISH/ VSV system, which was 3.3×105 IU/mL.

To explore the protective effects of trimetazidine on vascular endothelial cells injury induced by hydrogen peroxide (H2O2) and its pharmacological mechanisms of anti-oxidation.Methods Human umbilical vein endothelial cells (HUVECs) were injured by H2O2.Next,the cells were treated with three different concentrations of trimetazidine (1 μmol/L,10 μmol/L,100μmol/L,respectively).The viability of cells was detected by methyl thiazoeyl tetrazolium (MTT) assay.In addition,malondialdehyde (MDA)contents,superoxide dismutase (SOD) and secretion of NO were measured.Results Trimetazidine could enhance the viability of the injured HUVECs induced by oxidation,decrease the level of MDA,enhance the SOD activity,and increase the secretion of nitrogen monoxide.These effects were in a certain dose-dependent manner and the difference was significant among the three concentrations (P＜0.05).Conclusions Our results suggest that trimctazidine may protect lipid peroxidation and prevent oxidation-induced cellular dysfunction of HUVECs (J Geriatr Cardiol 2008;5:248-251)

OBJECTIVETo investigate the changes in the quantity of colonizing Streptococcus mutans(S. mutans) and Actinomyces on the root surface plaque before and after post-core crown restoration of the mandibular first molars in the elderly patients.

METHODSA total of 30 elderly patients, each with one post-core crown restoration of the mandibular first molar, were randomly chosen to participate in the studies. Patients with mandibular first molars with post-core crown restoration and those with healthy contralateral mandibular first molars were divided into the test and control groups, respectively. Root surface plaques of the two groups were collected before tooth preparation, 72 h after preparation, one week after preparation, and one month after restoration. S. mutans, Actinomyces naeslundii (A. naeslundii) and Actinomyces viscosus (A. viscosus), were identified using colony morphology, biochemical techniques, and polymerase chain reaction (PCR). Plaque count was measured using microbial colony count.

RESULTSThe number of S. mutans and A. viscosus and A. naeslundii in the test group, which was statistically significant (P<0.05), increased 72 h after preparation. The quantities of S. mutans, A. viscosus, and A. naeslundii one week after preparation were significantly different (P<0.05). The plaque count of S. mutans, A. viscosus, and A. naeslundii in the test group decreased one month after restoration (P<0.05).

CONCLUSIONThe quantities of S. mutans, A. viscosus and A. naeslundii increase one week after preparation but decrease one month after restoration. The finding suggests that dentists should educate patients about plaque control during the early period after tooth preparation.
