Objective To characterize clinical features,antimicrobial susceptibility and the outcome of nosocomial Acinetobacter baumannii meningitis.Methods All patients with nosocomial meningitis due to Acinetobacter baumannii in 2nd Affiliated Hospital Medical School of Zhejiang University between January 2010 and October 2011 were retrospectively reviewed.Results During the study period,40 patients of this nosocomial infection were identified,who came from neurosurgery ward (19 cases,47.5％),neurosurgieal intensive care unit (18 cases,45.0％),emergency intensive care unit (2 cases,5.0％) or intensive care unit (1 case,2.5％).All the patients had a history of recent neurosurgical procedures. Fever and disturbance of consciousness were the major manifestations,and cerebrospinal fluid examination showed elevated white blood ceil count and protein,and reduced glucose.All isolated pathogens were resistant to the first line antibiotics.The fatality rate was high. Conclusions The most common risk factor for nosocomial Acinetobacter baumannii meningitis is neurosurgery. Resistance to the first line antibiotics is common among all pathogens isolated.The prognosis of the meningitis is poor.

Objective To determine the role of C-reactive protein(CRP) in evaluating the activity of ulcerative colitis. Methods Analysis was used to estimate the correlation of CRP with mean platelet volume in 41 patients with active ulcerative colitis and 17 patients ulcerative colitis in re-mission. The effects on disease severity were analyzed subsequently. Results Active UC patients sera CRP level(8.58 ±2.43)mg/L,which level of severe UC CRP (14.38 ±4.46)mg/L,the moderate level of CRP UC(6.68 ±2.35)mg/L,mild level of CRP UC(4.94 ±1.21)mg/L, while the remission stage UC patients CRP levels(3.05 ±0. 88)mg/L. CRP was found to be significantly higher in sera of patients with active ulcerative colitis than that in patients in remission (P ＜ 0.05). The sera level of CRP in inflammatory bowel disease at severe stage were significantly higher than those of medium stage (P ＜ 0. 05). CRP was observed to be slightly increased in sera of patients at mild stage (P ＜ 0. 05). Conclusion The increase of CRP could reflect the severity of active ulcerative colitis.

Cotton (Gossypium hirsutum) is one of the most important economic crops in the world. Its growth and productivity were affected by environment stresses such as drought, cold and high salinity. Thus, the enhanced stress tolerance in this plant is of great importance. As the dehydration responsive element (DRE) binding protein (DBP) plays an important role in the regulation of plant resistance to environmental stresses and is quite useful for generating transgenic plants tolerant to these stresses, isolation and functional analysis of DBPs in cotton are important to cotton production. In the previous work, a DBP gene from cotton, named as GhDBP1, was isolated and its expression patterns in cotton plants was demonstrated at the transcriptional level. Here, the expression,purification and DNA binding activity of GhDBP1 were reported. The entire coding region of the GhDBP1 gene was inserted into an expression vector, pET28a, and transformed into Escherichia coli BL21 (DE3). The fusion protein was successfully expressed under IPTG induction and the purified recombinant protein was obtained by Ni-NTA affinity chromatography. Non-radioactive electrophoretic mobility shift assay revealed that the purified GhDBP1 protein was able to form a specific complex with the previously characterized DRE element. In addition, the computer modeling of the DNA-binding domain of GhDBP1 were performed using SWISS-MODEL software. The main-chain structures and the folding patterns of the DNA-binding domain of GhDBP1 were similar to the known structure of the DNA-binding domain of the Arabidopsis thaliana GCC box-binding protein AtERF1. These results indicate that GhDBP1 is a DRE-binding transcription factor and might use the structure similar to that of AtERF1 to interact with DRE sequence.

AIM To investigate if scallop (Placopecta magellanicus) skirt glycosaminoglycan (SS-GAG) inhibits the proliferation of vascular smooth muscle cell (VSMC) as heparin does so and to clarify its mechanism. METHODS The inhibitory effects of SS-GAG on the proliferation of rat thoracic aorta and abdominal aorta VSMC induced by fetal bovine serum (FBS) or basic fibroblast growth factor (bFGF) were determined by cell counting, crystal violet staining and MTT colorimetry. The effects of SS-GAG on the expression of proliferating cell nuclear antigen (PCNA) and platelet-derived growth factor (PDGF) in VSMC proliferation induced by bFGF were evaluated by immunohistochemical technique (LSAB method) and computer image analysis system. RESULTSSS-GAG exerted antagonistic effects on VSMC proliferation induced by 20% FBS and 50 μg·L-1 bFGF at concentrations ranging from 50 mg·L-1 to 200 mg·L-1 and repressed the increasing expression of PCNA and PDGF. CONCLUSION SS-GAG significantly inhibits the proliferation of VSMC, which may be carried out through repression of PDGF and PCNA expression.

BACKGROUND:K-wire and steel wire tension band wiring is the most commonly method for the treatment of patel ar fracture. However, there have been many reports of complications related to the mental implants. Based on the reasons above, some scholars begin to replace the steel wire with braided polyester sutures for the treatment of patel ar fracture. OBJECTIVE:To observe the effect of patel ar ring pins and FiberWire braided polyblend sutures tension band fixation for treatment of patel ar fracture. METHODS:We performed a retrospective analysis involving 26 patients with patel ar fracture (16 males, 10 females, at the age of 36-54 years with a mean age of 44.6 years) who were treated with patel ar ring pins and FiberWire braided polyblend sutures tension band fixation. RESULTS AND CONCLUSION:Al the patients were fol owed-up for 6-18 months, average of 12 months. Al patients were primary healing and achieved bone union in 8-16 weeks, averaged in 12 weeks from surgery. There was no fracture fragment displacement, internal fixation loosening and break. No pins protruding from the subcutaneous and irritate the skin. According to the Lysholm&Gil quist scales, 18 cases were excellent, four cases were good, and four cases were fair, with the excellent and good rate of 85%. Tension band fixation using patel ar ring pins and FiberWire braided polyblend sutures resulted in good outcomes with few complications.

The co-metabolic carbon sources,dynamics and influence factors of atrazine biotransformation by genetically engineered microor- ganism(GEM)were investigated in the paper.The results showed that glucose was superior to acetate as co-metabolic carbon sources.The concentration of carbon sources affected little on atrazine transformation but much on GEM growth.The specific transformation rate(STR)of atrazine was influenced not by cell density of GEM but by atrazine concentration.Monod model was used to simulate atrazine transformation dynamics and the parameters were v_(max)=0.168/h and Ks=30.49 mg/L.When temperature reduced,STR decreased markedly.The trans- formation was efficient in weak alkaline condition and was inhibited in acidic condition.To some extent,salinity did not affect transformation activity of GEM.Co~(2+),Fe~(2+),Fe~(3+),and Zn~(2+) improved atrazine transformation,but Mn~(2+),Ni~(2+) and Cu~(2+) inhibited atrazine transforma- tion.The results also showed that there existed a direct correlation between adsorption and transformation of atrazine by GEM.

Objective To evaluate the efficacy and safety of the intrathoracic injection of polysachride nucleic acid fraction of Bacillus Calmette Guerin(BCG PSN) combined with mitomycin and cisplatin for the treatment of lung cancer with malignant pleural effusion. Methods A total of 53 lung cancer patients with malignant pleural effusion were randomly divided into two groups: BCG PSN combined with chemotherapy group (treatment group, 27 patients) and simple chemotherapy group (control group, 26 patients). Drugs were injected into thoracic cavity, which was repeated every 7 day interval. Effective rate, Karnofsky score and toxicities were evaluated. Results After treatment, the effective rate was 88.8% in treatment group and 53 9% in the control group. Significant difference was found in the two groups( P

Apoptosis inhibitors ( inhibitor of apoptosis proteins, IAPs) are a class of highly conserved apoptotic endogenous anti-cytokine family, primarily by inhibiting caspase activity and par-ticipation in regulation of nuclear factor NF-κB inhibition of ap-optosis. caspases cascade of protease activation is a central part of the apoptotic process, Bcl-2 family proteins and IAPs family proteins are the main controlling factors. In recent years, we found that abnormal expression of some IAPs members is closely associated with the tumor, a potential target for cancer therapy. Therefore, this paper reviews the major protein associated with IAPs family and anti-tumor research targeting IAPs.
