Intracranial infection is a common and serious complication of acute severe traumatic brain injury, with high mortality and disability rates, which significantly affects the prognosis. In recent years, with the widespread use of antibiotics, antibiotic-resistance rates of pathogens have risen year by year, and the choice of sensitive antibiotics is less and less, sometimes even in difficulties of no drugs available. This paper reviewed the treatment process of 1 case with intracranial infection caused by multi drug-resistant Klebsiella pneumonia after severe traumatic brain injury . The aim is to summarize the clinical experience.

Benign prostatic hyperplasia (BPH) is one of the common urinary system diseases in middle-aged and elderly men, which seriously affects the health and quality of life of patients. At present, the pathogenesis of BPH is still unclear, which critically affects the effective treatment of BPH. In recent years, more and more animal experiments and clinical trials have shown that pollen preparations have a significant inhibitory effect on BPH. In this paper, the pathogenesis of BPH and the related researches on the treatment of BPH by pollen preparations were reviewed, and the effective components of pollen preparations were analyzed, so as to discover the mechanism of BPH inhibition by pollen preparations and finally achieve the purpose of comprehensive utilization.

Objective To evaluate the effect of sustained silencing Forkhead box Ml (F0XM1) gene by short-hairpin RNA (shRNA) expression vector on cell growth of hepatocelluar carcinoma (HCC) in vitro.Methods Four shRNA expression vectors targeting different sequences of human F0XM1 mRNA were constructed.The expression vector with the best interfering effect and the negative control plasmid were used to transfect HCC cell line QGY-7703, stably transfected cell clones were selected by neomycin (G418).Cell growth was evaluated by 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay and colony formation was assessed by clonogenic assay.Cell apoptosis was detected by double staining with APC conjugated Annexin V and PI.Results F0XM1 protein was detected with different levels in all these studied human cell lines.The expression vector shRNA-1026 exhibited excellent interference effect after transient transfection, which showed 38.5% and 53.2% reduction of FOXM1 mRNA and protein level respectively.The growth of QGY-7703 cells was inhibited after stable inhibition of FOXM1 expression by shRNA-1026, which was indicated by decreased absorbance value of the test group after culture for 48, 72 and 96 h compared to control group (t = 10.830,3.578 and 5.734 respectively, P < 0.05).Stable inhibition of F0XM1 also led to reduced colony formation ( t = 5.336, P < 0.05 ) and increased apoptosis of QGY-7703 cells in comparison to control cells (t = 6.827, P < 0.05 ).Conclusions Stable silencing F0XM1 gene by shRNA suppresses the growth of HCC cells in vitro.
