Objective To investigate the rehabilitation prognoses of children with traumatic brain injury (TBI).MethodsA retrospective analysis was made in 64 children who had been admitted for rehabilitation.Their clinical information,rehabilitation protocols,recovery of consciousness and ability in the activities of daily living (ADL) were analyzed. ResultsThe children's injuries were severe-42.19％ had consciousness disorders,but 80％ of them recovered consciousness after rehabilitation.Their limb motor dysfunction was dominated by hemiplegia (51.67％).For 65.63％ of the patients rehabilitation was initiated within one month after injury.The average length of stay in rehabilitation was 33.09 ± 25.96 days.Those with consciousness disorders stayed significantly longer than those without.The main treatments were hyperbaric oxygen therapy,exercise and neurotrophic drugs (the ratios were 95.31％,89.06％ and 82.81％ respectively).After the first course of inpatient rehabilitation,the conscious ness recovery rate was 81.48％ and ADL ability improved significantly.The total effectiveness rate was 90.63％.Univariate and multivariate analyses showed that the factors most strongly correlated with effective rehabilitation were age at injury and the rehabilitation intervention time.ConclusionThe results suggest that a general hospital should focus on early (acute and subacute phase) rehabilitation.So developing the rehabilitation network system is necessary and urgent.Rehabilitative therapy is very helpful in TBI cases.Being older at the time of injury and earlier rehabilitation intervention predict better short term outcomes.It is necessary to build and improve on a more standardized and systemic rehabilitation and assessment system for pediatric TBI.

Objective To compare the efficacy of endovascular interventional treatment and surgical clipping in posterior communicating artery aneurysm (PCoAA) patients with fetal-type posterior cerebral artery (fPCA).Methods The PCoAA patients with fPCA were enrolled.Their baseline clinical data were collected.The modified Rankin Scale (mRS) was used to assess the clinical outcomes at six months after procedure.The mRS score 0-2 was defined as good outcome.Results A total of 35 PCoAA patients with fPCA were enrolled into the study,23 were treated with interventional embolization therapy and 12 were treated with craniotomy clipping.There were no significant differences in age,gender,preoperative Fisher grade,Hunt-Hess grade,baseline GCS scores,and aneurysm typing between the 2 groups.The good outcome rate of the interventional embolization group at 6 months was higher than that of the surgical clipping group,but there was no significant difference (65.22％ vs.41.67％;P =0.282).Results The efficacy of PCoAA using interventional embolization therapy combined fPCA is almost the same as craniotomy clipping.

To investigate the safety and efficacy of capsular tension ring ( CTR ) insertion combined with phacoemulsification and intraocular lens ( lOL ) implantation in patient with pseudoexfoliation syndrome after anti-glaucoma surgery.
●METHODS: A retrospective study was conducted of 10 eyes from 10 cataract patients with pseudoexfoliation syndrome following trabeculectomy surgery, and who underwent CTR insertion combined with phacoemulsification and lOL implantation between January, 2012 and June, 2013. All cases had nuclear cataracts ( nuclear hardness Ⅱ 1 eye, nuclear hardnessⅢ 4 eyes, nuclear hardness Ⅳ 5 eyes). One case with Ⅳ nuclear hardness cataract had iridodonesis and lens subluxation. Postoperative visual acuity, intra- and post-operative complications, anterior capsular opening, lOL position, and postoperative intraocular pressure ( lOP) were assessed. Follow-ups ranged from 3 to 14mo. The t test was used to analyze the variables studied.
●RESULTS: All patients had a successful CTR insertion combined with phacoemulsification and lOL implantation. A modified CTR insertion was performed in one case, the others underwent a standard CTR insertion. The best corrected visual acuity ( BCVA) was≥0. 5 in 3 eyes and 0. 3-<0. 5 in 2 eyes. However, BCVA was ≤0. 1 in 5 eyes. No decentration and dislocation of lOL was found during follow - up. Optic atrophy of different level could be found in all cases. The mean lOP was 16. 78±2. 48mmHg before surgery. And the average lOP is 16. 01±2. 33mmHg at 3mo postoperative (t= 1. 9955, P>0. 05). The most common intrao- and post-operative complications were corneal edema, small pupil, residual cortex, spontaneous zonular dialysis.
● CONCLUSlON: Suitable CTR insertion in appropriate occasion may be beneficial to patients with pseudoexfoliation syndrome after trabeculectomy during cataract surgery. lt prevents the lOL decentration and decrease the surgical complication. Less complication occurs at the early stage.

ObjectiveTo investigate the loss of heterozygosity (LOH) on 6q in bladder tumor.MethodsD6S404 and D6434 microsatellite markers near 6q21 were tested by PCR-SSLP-stain method on tumor DNA from 31 cases of bladder tumor.ResultsAmong these 31 cases of bladder tumor,LOH was detected in tumor tissues on site for D6S404 (35.5%) and D6S434(22.6%).ConclusionOne or more tumor suppressor gene near 6q21 maybe relevant for the development of bladder tumor.

Eleven compounds were isolated from the culture of Streptomyces sp. CPCC 202950 by a combination of various chromatographic techniques including column chromatography over macroporous resin HP-20, MCI, and reversed-phase HPLC. Their structures were identified as 1H-pyrrole-2-carboxamide(1),5'-deoxy-5'-methylthioinosine(2), vanillamide(3), trans-3-methylthioacrylamide(4), 1,2,3,4-Tetraydro-1H-pyrido[3,4-b]indole-3-carboxylic acid(5), cyclo(L-pro-L-tyr) (6), N-[2-(4-hydroxyphenyl)]ethylacetamide(7), benzamide (8), cyclo ('L-leucyl-trans-4-hydroxy-L-proline)(9), cyclo-(Phe-Gly) (10), and tryptophan (11). Among them, compounds 1 and 2 were new natural products. In the preliminary assays, none of the compounds exhibited obvious inhibition of HIV-1 protease activity (IC50 > 10 micromol x L(-1)).

Guanylate-binding protein 1 (GBP1) is an interferon induced protein, that belongs to the guany late-binding protein family. GBP1 is widely involved in anti-infection immune responses, anti-tumor activity and various biological reactions. Recent studies have proved that IFN-alpha, IFN-beta, IFN-gamma, IL1alpha, IL1beta, TNF-alpha and LPS can induce GBP1 expression; hence, the diverse biological functions of GBP1 have been gradually deduced and exploited. Many studies have been performed over recent years to understand the exact mechanisms that underlie the anti-infection and anti-tumor properties of GBP1. This review describes the molecular structure, biological activity, anti-infective properties and other functions of GBP1, in order to provide insights into the divergent roles of GBP1 in the regulation of various biological processes.
