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.

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.

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.

OBJECTIVETo evaluate the morphological characteristics of alveolar bone defects of the patients with chronic periodontitis using cone-beam CT (CBCT).

METHODSSixty patients with chronic periodontitis were included in this study. CBCT was used to scan the alveolar bone and NNT software to measure the alveolar bone defects and bone loss types in different regions.

RESULTSSeventy-five percent (45/60) of the alveolar bone defect was the generalized type, 25% (15/60) was the localized type. In incisor and canine area, the defect of the mandibular alveolar bone was more severe than in the same sites of maxilla. There was less bone loss in the premolar area of mandible than in the same site of maxilla. In the mesial and buccal sites of mandibular molars and in the lingual site of maxillary molars, the most severe alveolar bone loss was found.

CONCLUSIONSThe obvious alveolar bone defect areas in chronic periodontitis were the palatal side of maxillary molars and the lingual side of mandibular incisors. CBCT can clearly demonstrate the degree of alveolar bone defects in different regions of chronic periodontitis.

OBJECTIVETo detect the susceptible alleles in generalized aggressive periodontitis patients and healthy controls and to analyze the effect of multi-alleles on the occurrence and development of generalized aggressive periodontitis.

METHODSPolymerase chain reaction and cleavage were used for detecting the frequencies of five susceptible genetic polymorphisms in generalized aggressive periodontitis patients and healthy controls. The results were analyzed by Z-score test and mean square analysis.

RESULTSThe frequencies of homozygous for HLA-DRB1* 1501 allele, TNF-A-308 allele II, IL-1B(+3953) allele II, vitamin D receptor allele A, T, estrogen receptor allele X in generalized aggressive periodontitis patients were higher than those in healthy controls. The persons who took more than three susceptible alleles (including three susceptible alleles) had more severe periodontal conditions than the ones who took less than three susceptible alleles (not including three susceptible alleles).

CONCLUSIONSHLA-DRB1 * 1501 allele, TNFA-308 allele II, IL-1B(+3953) allele II, vitamin D receptor allele A, T, estrogen receptor allele X are susceptible alleles in generalized aggressive periodontitis. Carrying more than three susceptible alleles has a great effect on the occurrence and development of generalized aggressive periodontitis.
