OBJECTIVETo explore the effects of a novel human chemokine-like factor 1 (CKLF1) on stem cell/progenitor cells.
METHODSHuman bone marrow mononuclear cells were separated by Ficoll (1.077 g/ml), and cultured in suspension and semisolid colony culture. The effects of CKLF1 on CFU-GM and CFU-Mix were observed.
RESULTSThe number of CFU-GM was significantly increased in 10 groups by addition of CKLF1 plasmid supernatant. The mean value was 234.81 +/- 98.71/1 x 10(5) cells, 2.42 fold of control group (P < 0.05). The mean value of CFU-Mix in groups of negative control, CKLF1, PHA, GM-CSF and G-CSF were 82.00 +/- 20.25, 105.76 +/- 36.70, 146.63 +/- 27.09, 143.33 +/- 60.23 per 1 x 10(5) cells, respectively, no statistical differences were seen between control and CKLF1 groups. The CD(34)(+) cells were detected by FACS. The average percentage in the groups of normal control, CKLF1, PHA and GM-CSF were (0.75 +/- 0.62)%, (1.32 +/- 0.87)%, (0.15 +/- 0.02)%, and (0.29 +/- 0.23)%, respectively. Compared with control, no significant differences were seen between each group (P > 0.05).
CONCLUSIONNovel chemokine-like factor 1 can increase the proliferation of CFU-GM, which indicated that CKLF1 could increase the proliferation of human bone marrow hematopoietic progenitor cells and colony formation.

Objective To explore the influence of lack of parental accompaniment, physical abuse and neglect in childhood on the psychological distress of college entrant students. Methods In a comprehensive university in Sichuan Province, 8367 freshmen were surveyed using the 6-item Kessler psychological distress (K6) scale and a questionnaire for lack of parental accompany, physical abuse and neglect in childhood. The students were divided into rural group and urban group for data analysis. Results The months of lack of maternal and/or paternal accompaniment were more in rural group than that in urban group (P<0.05). In rural group, female (standardizedβ’=0.139, P<0.001), neglect (standardizedβ’=0.237, P<0.001) and physical abuse (standardized β’=0.076, P<0.001) were associated with K6 scale. In urban group, female (standardizedβ’=0.091, P<0.001), lack of paternal accompaniment (standardizedβ’=0.050, P<0.001), ne? glect (standardized β’=0.169, P<0.001) and physical abuse (standardized β’=0.095, P<0.001) related with K6 scale. Conclusions Neglect and physical abuse are independent risk factors to freshmen both from rural and urban areas. Lack of paternal accompaniment in childhood is a risk factor only in urban freshmen. Further research should select more rep?resentative samples and also include more factors which may interact with the loss of parental accompaniment such as pa?rental divorce and conditions regarding so calledleft-behindchildren in rural area.

Objective To examine the clinical characteristics and red cell distribution width (RDW) changes and to investigate the prognostic value of RDW in elderly patients undergoing peritoneal dialysis(PD). Methods We retrospectively analyzed the data of 59 elderly patients aged 60 or over who had undergone regular PD for over three months at Beijing Hospital from July 1 ,2005 to June 30 ,2017.All patients were followed up until the occurrence of a composite event or until December 31 ,2017. General characteristics ,baseline laboratory data ,RDW at baseline ,and time-average RDW during the follow-up were compared between the non-survival group and the survival group.Cox regression analysis was performed to determine whether RDW was an independent risk factor of all-cause mortality. Results Fifty-nine elderly PD patients with a mean age of (70.5 ± 6.6) years were included.The median follow-up duration was 40(25 ,56)months and the median survival duration was 57(36.6 ,74.4)months. The 1-,3-,and 5-year survival rates of all patients were 98.3%(n=58) ,72.9%(n= 43) ,and 52.5%(n= 31) ,respectively.Twenty-eight patients died during the follow-up ,of whom 15 died of infection ,8 of cardio-cerebrovascular disease and 5 of other causes.Non-survivors had higher Charlson Comorbidity Index (CCI)scores ,higher levels of RDW at baseline ,higher time-average RDW ,lower initial total KT/V ,and lower initial total CCr (all P<0.01).In univariate analysis ,high CCI ,high basic RDW ,high time-average RDW ,low serum albumin ,low serum ferrum , and low serum cholesterol were associated with all-cause mortality (all P< 0.05).In multivariate- adjusted Cox analysis ,high CCI(HR=1.679 ,95% CI :1.238-2.236 ,P=0.001)and high time-average RDW(HR = 1.889 ,95% CI :1.195-2.987 ,P = 0.007)were independent predictors for all-cause mortality in elderly PD patients. Conclusions Time-average RDW may independently predict the mortality of elderly PD patients. The prognostic value of dynamic RDW may be similar to that of CCI.

OBJECTIVE: To explore whether MRI fusion technology (combined T2-weighted imaging [T2WI] and fat-suppressed T2WI [T2WI-(FS)]) improves signal differences between anal fistulas and surrounding structures. MATERIALS AND METHODS: A total of 32 patients with confirmed diagnoses of anal fistula were retrospectively studied. All available T2WI and T2WI-(FS) images for each patient were used to generate fusion image (T2WI-(Fusion)) based on the addition of gray values obtained from each pixel via an MR post-processing work station. The discriminability of fistula, perianal sphincter, and perianal fat in T2WI, T2WI-(FS), and T2WI-(Fusion) images was quantified with Fisher's scoring algorithm. For subjective visual image assessment by researchers, five-point scale scores were determined using a modified double-stimulus continuous quality-scale test to evaluate T2WI-(FS), T2WI, enhanced axial three-dimensional-volumetric interpolated breath-hold examination (3D-VIBE), and T2WI-(Fusion) sequence images. The differences were subsequently compared. RESULTS: Mean Fisher scores for fistulas vs. sphincters obtained from T2WI-(Fusion) (F(Fusion-fistula) = 6.56) were significantly higher than those from T2WI (F(T2WI-fistula) = 3.35) (p = 0.001). Mean Fisher scores for sphincters vs. fat from T2WI-(Fusion) (F(Fusion-sphincter) = 10.84) were significantly higher than those from T2WI-(FS) (FS(FS-sphincter) = 2.57) (p = 0.001). In human assessment, T2WI-(Fusion) showed the same fistula discriminability as T2WI-(FS), and better sphincter discriminability than T2WI. Overall, T2WI-(Fusion) showed better discriminability than T2WI, T2WI-(FS), and enhanced 3D-VIBE images. CONCLUSION: T2WI and T2WI-(FS) fusion technology improves signal differences between anal fistulas and surrounding structures, and may facilitate better evaluation of anal fistulas and sphincters.
