BACKGROUND: High mobility group box 1 protein (HMGB1) is a highly conserved, ubiquitous protein in the nuclei and cytoplasm of nearly all cell types. HMGB1 is secreted into the extracellular milieu and acts as a proinflammatory cytokine. In this article we reviewed briefly the cellular immune response mediated by HMGB1 in inflammation and sepsis. METHODS: This systemic review is mainly based on our own work and other related reports. RESULTS: HMGB1 can actively affect the immune functions of many types of cells including T lymphocytes, regulatory T cells (Tregs), dendritic cells (DCs), macrophages, and natural killer cells (NK cells). Various cellular responses can be mediated by HMGB1 which binds to cell-surface receptors [e.g., the receptor for advanced glycation end products (RAGE), Toll-like receptor (TLR)2, and TLR4]. Anti-HMGB1 treatment, such as anti-HMGB1 polyclonal or monoclonal antibodies, inhibitors (e.g., ethyl pyruvate) and antagonists (e.g., A box), can protect against sepsis lethality and give a wider window for the treatment opportunity. CONCLUSION: HMGB1 is an attractive target for the development of new therapeutic strategies in the treatment of patients with septic complications.

OBJECTIVETo analyze the causes of delayed union or nonunion of the ulna after intramedullary nailing in pediatric forearm fractures.

METHODSFrom February 2005 to February 2010,5 patients with forearm fractures who were treated with titanium elastic nailing (TEN) were identified to fulfill the criteria of having developed a delayed union or nonunion of the ulna. The causes of delayed union or nonunion were investigated according to mechanism of injury, fracture location, treatments methods and postoperative management. All patients were male and the age was 3 to 14 years old with an average of 9.4 years. All fractures were located on the mid-third part of forearm. Two cases had a re-fracture. Among them, 3 cases caused by high-energy injury and 2 cases by falling down. Open reduction were performed in 4 cases while the other one was treated with closed reduction. Four patients were immobilized in an above-elbow cast, postoperatively.

RESULTSAll patients were followed up from 7 to 19 months with an average of 11.4 months. There were 4 delayed union and 1 nonunion. Three patients healed after the removal of the nail and avoidance of weight-bearing. Two patients healed by replacing another fixation. No patients had soft-tissue irritation or nail-entry-site infections.. The clinical effect was evaluated according to Daruwalla and Price scores with 3 excellent and 2 good of the results.

CONCLUSIONSUsing titanium elastic nailing for the treatment of pediatric both-bone forearm fractures is a good method. However,strict indication selection should be followed to avoid delayed union or nonunion.

OBJECTIVEThe research aimed at studying the biological characteristics of rhizobia isolated from Abrus cantoniensis.

METHODThe rhizobia strains, isolated from different environments in Guangxi, were studied for their growing characters and the generation time. They were also compared for survival capabilities under stresses caused by NaCl, pH, temperature, and different kinds and concentration of antibiotics.

RESULTThe strains obtained from A. cantoniensis in subtropical zone produced alkali in YMA medium, the average generation time was 14.8 hours, and thus they belong to slow-growing rhizobia. Rhizobia strains differed greatly in respect to tolerance of high temperature, adaptability of acidic environment and sensitivity to four antibiotics, but they had the same abilities of using different carbon and nitrogen sources. After 70 days from inoculated strains, the seedling formed nodules on the root (85.0%), and the dry matter of vine was increased by 51.1%.

CONCLUSIONThe rhizobia strains isolated from different ecological environments are good germplasm resources of tolerances to high temperature and acidic environment. The research will greatly help utilize the rhizobia resources and enhance the quality of crude drugs of medicinal leguminosae.

OBJECTIVETo compare the relative characteristics of Baihui (GV 20), Shuigou (GV 26) and Shenmen (HT 7) in treatment of vascular dementia.

METHODSFifty cases of vascular dementia (VD) were divided into 5 groups randomly. The patients in the group A were treated by acupuncture at routine acupoints. Besides the routine acupoints of the group A, Baihui (GV 20), Shuigou (GV 26) and Shenmen (HT 7) were added to treat the patients in group B, C, D, respectively, while Baihui, Shuigou and Shenmen were added to the group E. The clinical symptoms and signs were observed.

RESULTSBaihui and Shenmen can improve memory, orientation, reaction, obstinacy and trance of VD patients. Baihui is good at helping the patients to understand, calculate and adapt the society. Shuigou is good at improvement of sleeping, slow reaction, trance and memory of the patients. The combination of Baihui, Shuigou and Shenmen can generally promote intelligence level and society adaptive ability.

CONCLUSIONBaihui, Shuigou and Shenmen have own characteristics in improving clinical signs and intelligence of patients of VD, and the combination of the 3 acupoints has the best effect in treating VD.

OBJECTIVEUsing methods of clinical scale assessment and cerebral functional imaging to compare the relative specificity of needling acupoints Baihui (DU20), Shuigou (DU26) and Shenmen (HT7) in intervening vascular dementia (VD) in different areas in the brain.

METHODSFifty patients with VD were randomized into 5 groups. Needling on conventionally used acupoints of hand and foot three Yang-meridians aiming at hemiplegia was applied to the patients in Group A, and needling on DU20 to Group B, on DU26 to Group C, on HT7 to Group D and on all the three to Group E was applied additionally. Assessments of Mini Mental State Examination (MMSE), Activities of Daily Living (ADL) and Family Attitude Questionnaire (FAQ) were made. And the positron emission computerized tomography (PET) and single photon emission computerized tomography (SPECT) examinations were conducted in 5 selected patients from each group before and after treatment.

RESULTSNeedling on conventional acupoints plus DU20 could effect the inner temporal system, thalamencephalon system and prefrontal cortical system to improve memory and executive capacity of VD patients; conventional acupoints plus DU26 could effect more to the prefrontal cortical system to obviously elevate the executive capacity; that plus HT7 would reveal an effect similar to but rather weaker than plus DU20, and effect more to memory; and that plus all the three simultaneously could effect rather roundly multiple aspects of the nervous system related to intellectual activities, to elevate the recognition and enhance the executive capacity.

CONCLUSIONNeedling on various acupoints like DU20, DU26 and HT7 have effects on different brain areas.

Purpose To detect the expression of CD90 in invasive ductal breast carcinoma with different molecular subtypes and to explore its clinical significance.Methods The expression of CD90,ER,PR,Ki-67 and HER-2 were detected in 80 cases of invasive ductal breast carcinoma tissue and 20 cases of breast benign lesion with immunohistochemical method.The relationship between CD90 and clinicopathological parameters were analyzed.Results The positive expression rate of CD90 in invasive ductal breast carcinoma and breast benign lesion tissues were 62.5％ and 20.0％,respectively (P ＜0.001).The expression of CD90 in invasive ductal breast carcinoma was correlated with lymph node metastasis (P ＜ 0.05),but not with age,tumor size,TNM staging and histological grade (P ＞ 0.05).Among different molecular subtypes,CD90 expression level in Luminal A type was the lowest (40.0％),and the level in triple negative type was the highest (82.4％) (P ＜0.05).CD90 expression level was negatively correlated with ER (r=-0.342,P＜0.05) orPR (r=-0.374,P＜0.05) expression level,but not with Ki-67 (r =0.084,P ＞ 0.05).Condusion The over-expression of CD90 is related with molecular subtypes of breast carcinoma,and its high expression suggests a poor prognosis.

The highly-pathogenic EV71 strain is the primary cause of mortality in hand-foot-and-mouth disease (HFMD) associated with neurological symptoms, for which no clinically effective drugs or vaccines exist. This study aimed to construct infectious cDNA clones of the EV71 highly-pathogenic strain and the cell-culture adapted strain using a reverse genetics approach. The genomic RNAs of EV71 parent strains were used as the templates for RT-PCR amplification, and then the PCR products that overlapped the full-length genome were connected into the pBR322 vector to produce infectious clones of pEV71 (HP) and pEV71 (CCA), respectively. The results showed that the HP strain propagated much more quickly than the CCA strain. The rescued viruses derived from the infectious clones not only maintained their consistency with their parent strains in terms of genomic sequences, but also retained their respective biological phenotypes. This research will contribute to our understanding of EV71 pathogenesis and the development of novel vaccines against HFMD.
