BACKGROUND:The production and release of a large amount of inflammatory factors caused by immune system inflammatory response mainly contributes to secondary spinal cord injury. OBJECTIVE:To investigate the effects of umbilical cord Wharton’s jely mesenchymal stem cel transplantation on repair of injured neurological function and expression of inflammatory factors monocyte chemoattractant protein 1 and interleukin 10 in rats with acute spinal cord injury. METHODS: Eighty-one healthy adult male Sprague-Dawley rats were randomly and equaly divided into sham operation, model and cel transplantation groups, with 27 rats per group. Rats in the latter two groups were subjected to hemisection of the spinal cord to establish acute spinal cord injury models. Rat models in the cel transplantation group received umbilical cord Wharton’s jely mesenchymal stem cel injection (1×106)via the tail vein. Rat neurological function was evaluated using the BBB score at different time points after spinal cord injury. The expression of monocyte chemoattractant protein 1 and interleukin 10 in injured spinal cord tissue was detected using ELISA assay at different time points after spinal cord injury. Migration and neuronal differentiation of umbilical cord Wharton’s jely mesenchymal stem cels in the injured spinal cord tissue were determined using immunohistochemical staining method. RESULTS AND CONCLUSION:Compared with the sham operation and model groups, rat neurological function was significantly recovered in the cel transplantation group (P < 0.05). Compared to the model group, monocyte chemoattractant protein 1 level in the serum and monocyte chemoattractant protein 1 mRNA and protein expression in the injured spinal cord tissue were significantly lower (P < 0.05), but interleukin 10 mRNA and protein expression in the injured spinal cord tissue was significantly higher (P < 0.05), in the cel transplantation group. In the cel transplantation group, umbilical cord Wharton’s jely mesenchymal stem cels could migrate to the injured region and express glial fibrilary acidic protein. These findings suggest that umbilical cord Wharton’s jely mesenchymal stem cels promote rat neurological function recovery by regulating the inflammatory response in the injured spinal cord tissue, which is likely to be one of mechanisms by which transplantation of umbilical cord Wharton’s jely mesenchymal stem cels treats spinal cord injury.

Objective To evaluate the effects of community-based rehabilitation therapy on activitv of daily living performance of the Chinese stroke patients. Methods In a single blinded,randomized,controlled multicenter trial,737 consecutive stroke patients were stratified by two groups of cerebral infarction and hemorrhage. All the patients were randomly divided into a rehabilitation group and a control group.The patients in the rehabilitation group received atandardized community-based rehabilitation therapy,while those in the control group did not.All the patients were followed up for 5 months for evaluation of their performance with activity of daily living by using Modified Barthel Index before intervention,after follow-up 2 and 5 months,respectively. Results Patients in the rehabilitation group performed better in ADL as reflected by the Modified Barthel Index score than those in the control group after 5 months of intervention(P＜0.05).Although both the rehabilitation group and control group improved over time,the rehabilitation group showed a greater improvement with the Modified Barthel Index scores when compared with the control group(P＜0.01).After 5 months follow-up,the total gain of Modified Barthel Index scores was 26.28 and 32.89 for those with cerebral infarction and hemorrhage,respectively,in the rehabilitation group. In comparison,the gain of Modified Barthel Index scores was 7.65 and 2 1.70 for those with cerebral infarction and those with hemorrhage,respectively in the control group.This implies a difference in improvement of 1 8.63 in cerebral infarction group and 1 1.19 in hemorrhage group,in favor of the rehabilitation group. Conclusion Standardized community-based rehabilitation therapy may help stroke patients to improve their performance in activity of daily living significantly.

OBJECTIVETo study the effect and mechanism of bevacizumab on proliferation and invasion of human lung cancer A549 cells.

METHODSA549 cells were treated with bevacizumab. Proliferation and invasion of the bevacizumab-treated A549 cells were detected using cell counting kit CCK-8 and Transwell assay, respectively. The expression of the mRNA and protein of MMP-2, MMP-9 and c-Met were detected by real-time PCR and Western blotting, respectively.

RESULTSProliferation activity was inhibited at the concentration of 10 µg/ml and promoted at the concentration of 100 µg/ml bevacizumab. Bevacizumab in the concentration of 50 µg/ml had a stronger inhibitory effect on the invasion of A549 cells (16 406.19 ± 5 674.23 penetrated cells) than that of control group (36 108.68 6 263.83, P<0.05). The real-time PCR showed that bevacizumab had a stronger inhibitory effect on the expression of MMP-2 and MMP-9 mRNA at the concentration of 50 µg/ml and on the expression c-Met mRNA at the concentration of 10 µg/ml bevacizumabin the A549 cells. However bevacizumab at the concentration of 100 µg/ml showed a promoting effect on the expression of MMP-2, MMP-9 and c-Met mRNA (1.82 ± 0.31, 1.60 ± 0.25, 2.63 ± 0.48), significantly higher than that of the control group (1.00 ± 0.19, 1.00 ± 0.23, 1.00 ± 0.22, P<0.05). The expression of MMP-2, MMP-9 and c-Met mRNA and protein was inhibited by 10 µg/ml bevacizumab in a time-dependent manner. The Western blot assay showed that bevacizumab had a bi-directional effect on the expression of MMP-2 and c-Met proteins in the A549 cells: a promoting effect at 100 µg/ml and inhibitory effect on the expression of MMP-2 at 50 µg/ml bevacizumab, and inhibitory effect on the expression of c-Met protein at 10 µg/ml bevacizumab.

CONCLUSIONSOur findings indicate that in a certain range of concentrations, bevacizumab has prominent inhibitory effect on the proliferation and invasion of A549 cells. However,over the concentration of 100 µg/ml, bevacizumab shows a weakening anti-invasion effect, even has a promoting effect on cell proliferation. This phenomenon may be related to the inhibiting effect on the expression of MMP-2 and c-Met proteins in a non-concentration-dependent manner by bevacizumab.

OBJECTIVESelecting variable-number tandem-repeat (VNTR) loci for different serogroups of Shigella spp to explore and establish multilocus variable-number tandem-repeat analysis (MLVA) method, in order to study the molecular characteristic of the isolated strains.

METHODSOf the Shigella strains found by dysentery surveillance in Beijing from 2001 to 2009, 180 strains were selected for this study, according to the number and serotypes of the surveillant strains, at the ratio of 15%; including 50 strains of Shigella sonnei and 130 strains of Shigella flexneri. After screening the polymorphism of the 18 VNTR loci, 10 VNTR loci (sh1-sh10) were retained and constructed three groups of multi-PCR methods to detect all he 180 strains and analyze MLVA molecular subtypes using capillary segments.

RESULTSA range of 2 to 11 alleles were found on the 10 VNTR loci among the 180 Shigella strains, with a diversity index value between 0.158 and 0.766. The 10 loci showed diversity in different serogroups, such as only one allele found in sh6 of Shigella flexneri, sh2 and sh3 of Shigella sonnei individually. The isolated 180 strains were divided into 84 MLVA subtypes, with a resolution ratio D value at 0.967 (95%CI: 0.956 - 0.978). The 130 strains of Shigella flexneri were divided into 63 subtypes, named as TF001-TF063; among which TF001, TF002 and TF 005 were the dominant subtypes, accounting to 17, 16 and 15 strains respectively. The 50 strains of Shigella sonnei were divided into 21 subtypes, named as TS001-TS021; among which TS002 (14 strains) and TS001 (7 strains) were the dominant subtypes.

CONCLUSIONMLVA subtyping method including 10 VNTR loci was preliminarily developed. The MLVA cluster analysis revealed that the subtypes of Shigella strains isolated in Beijing were diverse, and suggested the possibility of multiple-clone source.

Objective:To investigate clinical significance of Presepsin(soluble CD14 subtype) in the diagnosis and condition assessment of sepsis in children compared with traditional biomarkers.Methods:For the prospective study, 102 children with sepsis admitted to the PICU of the Children′s Hospital of the Capital Institute of Pediatrics from January 2017 to December 2018 were selected, including 57 cases in the sepsis group, 45 cases in the severe sepsis/septic shock group and 25 cases in the non-infectious systemic inflammatory response syndrome(SIRS group), and 35 children with healthy physical examination during the same period as the control group.The sepsis group was further divided into the survival group( n=86)and the death group( n=16)based on the 28-day mortality.The data collected included serum Presepsin, procalcitonin(PCT), C-reaction protein(CRP) and interleukin(IL)-6 levels on days 1, 3 and 7 of admission, and compared with paediatric critical case scores. Results:(1)The levels of serum Presepsin [12.43(7.21, 15.07) ng/mL], PCT [23.00(5.70, 87.00) ng/mL], CRP [160.0(105.5, 200.0) mg/L], IL-6 [1 000.0(125.0, 1, 000.0) pg/mL] were significantly higher than those in the sepsis, SIRS and control groups( P<0.001). (2) The area under the ROC curve(AUC) values for Presepsin, PCT, and IL-6 subjects on day 1 of admission were 0.856, 0.812, and 0.516, respectively.The sensitivity of Presepsin at a cut-off value of 4.40 ng/mL for the diagnosis of sepsis was 81.1% and the specificity was 72.3%, which would significantly higher diagnostic efficacy of the combination of Presepsin, PCT and IL-6.(3) There was a significant difference between the survival and death groups in Presepsin( P<0.001), and Presepsin was significantly higher in the death group on days 3 and 7 than those in the survival group(both P<0.001); IL-6 was significantly higher in the death group on day 3 than that in the survival group( P=0.04); the differences in PCT and CRP between the death and survival groups at all time points were not statistically significant(both P>0.05 ). (4) The AUCs of inflammatory factors on days 1, 3 and 7 to predict sepsis outcome were 0.597, 0.656 and 0.951 for Presepsin, 0.576, 0.613 and 0.655 for PCT and 0.726, 0.786 and 0.664 for IL-6, respectively.The diagnostic values of Presepsin on day 7 and IL-6 on days 1 and 3 were higher.The combination of Presepsin, PCT and IL-6 significantly improved the prognostic judgment of sepsis.(5) The difference between sepsis-related acute kidney injury(AKI) and non-AKI was not statistically significant when comparing Presepsin on day 1 and 3(all P>0.05). Presepsin levels on day 7 were significantly higher in children with sepsis-associated AKI than in those without AKI( P<0.001). Conclusion:Presepsin is a good biomarker for sepsis diagnosis in children, which is equivalent to PCT in the diagnosis of sepsis, superior to IL-6 and superior to PCT in the prognosis evaluation.Combined testing of Presepsin, PCT and IL-6 may improve the diagnosis of sepsis and the assessment of the condition in children.

BACKGROUNDAlthough many midterm oncologic data have been reported for extraperitoneal laparoscopic radical prostatectomy (ELRP) in western countries, few oncologic data of the extraperitoneal procedure was published in China. The aim of the study was to evaluate the oncologic outcomes of patients treated with ELRP in China.

METHODSFrom January 2005 to March 2010, a total of 152 consecutive patients diagnosed with clinically localized prostate cancer were included in this study and treated with ELRP. The patients were staged according to the TNM (tumor, nodes, metastases) system. Median and mean postoperative follow-up were 28.1 months and 27.0 months, respectively. The patients were retrospectively analyzed for progression-free survival.

RESULTSOne hundred and twelve cases (73.7%) were postoperatively diagnosed as pT2 in, and 40 cases (26.3%) as pT3. Positive lymph nodes were shown in 5 patients (3.3%). Gleason score was < 7 in 49 men (32.2%), 7 in 69 men (45.4%), and > 7 in 34 men (22.4%). Positive surgical margins (PSM) were observed in 15 patients (9.9%), which included 32.0% of all pT3a cases and 46.7% of all pT3b cases, respectively. The overall prostate-specific antigen recurrence-free survival rate was 86% in all patients. The recurrence-free survival rates were 91.8% and 62.2% in pT2N0 patients and pT3N0 patients, respectively. Preoperative prostate-specific antigen, surgical margins, tumor stage, and lymph nodal status were identified as independent predictors of biochemical recurrence-free survival using multivariate Cox proportional hazard model.

CONCLUSIONSELRP is a precise, safe and effective procedure at this particular Chinese institution. The prognostic power of prostate-specific antigen relapse after ELRP is not identical to that described previously with transperitoneal or open retropubic approaches.
