AIM: To investigate whether the bacterial DNA participates in SIRS and its possible mechanism. METHODS: Escherichia coli genomic DNA (EC DNA) was extracted and purified from Escherichia coli 25922 by alkaline lysis method. Mortality of mice challenged with EC DNA and the changes of TNF-? and IL-6 in rat serum were observed. ANA-1 cells were cultured in vitro, after the cells were stimulated by different concentrations of EC DNA and LPS, the level of TNF-? and IL-6 in supernatant were tested. Meanwhile,expression of TLR9 and TLR4 on cell surface was measured. Activation of NF-?B was also observed. RESULTS: The lethal effect of EC DNA on mice with an obvious dose-effect relationship was observed. The death happened within 24 hours. Calf thymus DNA and DNase I-treated EC DNA did not lead to mice to die. The changes of serum TNF-? and IL-6 in rats induced by EC DNA and LPS were similar, but TNF-? peak level of EC DNA group appeared 1 hour earlier than that of LPS group. In vitro, large amount of TNF-? and IL-6 were released from ANA-1 cells stimulated by EC DNA. High expression of TLR9 and TLR4 was observed on surfaces of THP-1 cells. In particularly, LPS induced strong activation of NF?B. The results suggested other pathway possibly took part in the signal transduction inducea by EC DNA. CONCLUSION: EC DNA has the abilities to lead to death of mice, and induces serum TNF-? and IL-6 level to increase in rats and ANA-1 cells to release cytokines in vitro. High expression of TLR9 and TLR4, strong activation of NF-?B may be its important molecular mechanism, but other pathway probably exists to play an important role.

Objective To learn the current culture of the hospital and identify its future development pathway. Methods The current culture types of the hospital are evenly distributed among the four quadrants. Results These types are found to be identically distributed among the tribe type, temporary system type, hierarchy type and market-oriented type of culture. Among these four type, the hierarchy type and market-oriented type score higher (27 scores both) and take the lead. Conclusions Hospitals are expected to enhance its exchange and communication with the employees, and head to its desired direction of a hospital culture type.

OBJECTIVETo explore activity laws of mitochondrial complex II in patients of deficiency-cold syndrome (DCS) and deficiency-heat syndrome (DHS) under various ambient temperatures.
METHODSSubjects were recruited by questionnaire and expert diagnosis from grade 1 - 3 undergraduates at Henan College of Traditional Chinese Medicine in November 2012, and assigned to a normal control group, the DCS group, and the DHS group, 20 in each group. Their venous blood samples were collected at two different temperature conditions. Activities of mitochondrial complex II were measured by spectrophotometry.
RESULTS(1) Comparison of mitochondrial complex It under various ambient temperatures: Compared with room temperature in the same group, activity values were all increased in the normal control group at cold temperature with significant difference (P <0.05), but there was no significant difference in the DCS group and the DHS group (P >0. 05). Compared with the normal control group, activity values of complex H were reduced in the DCS group at cold and room temperatures with significant difference (P <0.05). Compared with the DCS group, activity values of complex It were increased in the DHS group with significant difference (P <0. 05). (2) Changes of adjustment rates: Compared with room temperature, the adjustment rate all rose at cold temperature in the normal control group and the DHS group with significant difference (P <0.05), but with no significant difference found in the DCS group (P >0. 05). Compared with the normal control group at the same temperature, the adjustment rate in the DHS group and the DCS group was all reduced at cold and room temperatures with significant difference (P <0. 05). There were no significant difference in the adjustment rate between the DHS group and the DCS group (P > 0. 05).
CONCLUSIONSEnvironment temperature can affect the activity of mitochondrial complex II with different influence degrees on different syndrome types of people, but its change trend are basically identical.

Candida shehatae xyl1 gene and Pichia stipitis xyl2 gene were amplified by PCR and the xyl1 and xyl2 were both placed under the promoter GAL of vector pYES2 to produce the recombinant expression vector pYES2-P12. Subsequently the pYES2-P12 vector was transformed into S. cerevisiae YS58 by LiAc to produce the recombinant yeast YSS8-12. It was indicate that the recombinant yeast YSS8-12 could converse xylose to ethanol with the xylose consumption rate of 81. 3%.

Objective To investigate clinical value of inflame factors in child patients with sepsis at different time points before the diagnosis time.Methods A retrospective model was performed in this study.24 child patients with sepsis in Department of Paediatrics from January 2014 to October 2016 were selected.At the time 72 h(group A),48 h(group B),24 h(group C) before the diagnosis time,plasma levels of HBP and serum levels of IL-6,IL-10 were detected by ELISA,and pre calcitonin (PCT) and high sensitive C reactive protein (hs-CRP) were detected by immunofluorescence.Compared to the same period,22 healthy cases were selected as the control.Repeated measure anova and Receiver operating characteristic curve analysis were performed.Results The plasma levels of HBP were (9.69 ± 1.30) μg/L,(12.82 ±2.03) μg/L,(15.46 ± 1.02) μg/L,(18.60 ± 1.10) μg/L at group A,group B,group C before the diagnosis time respectively.The plasma levels of HBP at all time points before the diagnosis time were significantly higher than the control (t =6.27,P < 0.01;t =16.82,P < 0.01;t =25.16,P < 0.01).The serum levels of HBP at group B,group C were significantly higher than the last time point (t =5.62,P <0.01;t =10.25,P < 0.01).Receiver operating characteristic curve(ROC) revealed that the areas of HBP at group A(0.823),group B (0.898),was significantly higher than the other inflame factors(Z =2.41,P <0.01;Z=2.02,P<0.05;Z=0.38,P>0.05;Z=0.32,P>0.05)(Z=0.43,P>0.05;Z=0.46,P>0.05;Z =0.26,P > 0.05;Z =0.57,P > 0.05).It also revealed that at group C,area of PCT(0.941) was significantly higher than the other inflame factors (Z =0.12,P > 0.05;Z =0.08,P > 0.05;Z =0.03,P >0.05;Z-0.10,P > 0.05).Conclusions HBP has a wide diagnostic window period for sepsis.IL-6,IL-10,PCT and hs-CRP have diagnostic value in partial periods of sepsis.
10.Clinical pathological feature of early tongue amyloidosis.
Chinese Medical Sciences Journal 2006;21(2):104-106
OBJECTIVETo investigate the clinical pathological feature and diagnostic criteria of tongue amyloidosis (AL).
METHODSDuring 1992 to 2005, 25 patients pathologically diagnosed as tongue AL in our hospital were reviewed retrospectively, and all of them had no enlarged tongue. Haematoxylin and eosin (HE) and immunohistochemical staining were used to detect the amyloid deposition on the tongue.
RESULTSTotally 84% (21/25) patients had symptoms of xerostomia and taste-blindness, 44% (11/25) patients complained of activity limitation of tongue. Macroscopic observation showed mucosa pallescence, punctuate hemorrhage, red grain particles, and ulcers on the tongue. HE staining indicated amyloid depositions in basement membrane, muscle cell, vessel wall, and nerve fiber. Immunohistochemical study demonstrated kappa light-chain deposition in 64% (16/25) cases, and lambda light-chain deposition in 36% (9/25) cases. They presented in vessel wall, nerve fiber, and muscle cells.
CONCLUSIONThe biopsy is an important means for the diagnosis of early tongue AL, and the wide variety of amyloid light chain is helpful to differential diagnosis.
